provisional patent application is incorporated by reference herein in its entirety.
BACKGROUND
[0002] Modern toilets, such as flush toilets, generally include a bowl which is configured to
receive human waste and transport the waste from the bowl to a sewer line. Flush toilets also
10 typically include a tank used to supply fresh water to the bowl for a flushing and rinsing cycle, a
trap configured to evacuate wastc from the bowl and into the sewer line, and various toilet
attachments. Typical toilet attachments may include a seat attachment, a lid attachment, and a
bidet attachment.
100031 The water supplied to the bowl of a toilet for a flushing or rinsing cycle may enter the
15 bowl from a series of holes. The holes are generally located along various portions of a rim of
the toilet. A typical rim of a toilet may have a bottom wall, which is generally parallel with the
floor when the toilet is ~nounted in an installed state. Also, the bottom wall oftlie rim is
generally positioned above an upper and outer portion of the bowl. The various rim holes of a
typical toilet may typically be disposed within the bottom wall of the rim, and a bore of the holes
20 is generally perpendicular to the botto~nw all.

DETAILED DESCRII'TION
(00281 Toilets {nay be mounted in a variety of ways, but generally toilets eithcr mount to a
floor, or a wall. Typically, fasteners are used to mount a wall-hung toilet to a wall, and the
fasteners are visible from the front or side of the toilet. The fasteners, if visible, detract from the
aesthetics and potentially provide cleanliness issues, since they may collect contaminants (e.g.,
dirt, urine) and may be more difficult to clean.
(00291 Certain toilet attachments and other toilet accessories, such as bidets, may include an
5 electrical cord, a water line, or another type of line. When these components are used with a
typical toilet, the various lines of the components may extend outside the toilet to an electrical
outlet or a water connection along a nearby wall or the floor.
[0030] A wall-hung toilet may include a side pocket, If the side pocket for a wall-hung toilet is
small, then it difficult for a hand to be received within the pocket. If the pocket is left u~tcovered
lo (i.e., openly disposed), then thc inside of the side pocket remains visible liom the side or f'ront of
a toilet. It is advantageous to cover the pocket and to have the pocket large enough to fit a hand
inside thc pocket.
[0031] A wall-hung toilet may include an exterior surface proximate the sides and front of the
bowl that is convex in curvature. The convex curvature of a wall-hung toilet curves outward
15 toward the floor and the area surrounding a toilet, which may leave less room to clean around thc
toilet.
[0032] The exemplary e~nbodimentso f the wall-hung toilets disclosed herein address one or
more of the aforementioned issues.
[0033] FIG. I illustrates an exemplary embodiment of a toilet 10, which rnay be configured as
20 a wall-hung toilet. In othcr words, the toilet 10 may be configured to mount to a wall, as
opposed to resting on the floor. FIG. 4 illustrates the toilet 10 mo~~ntetod a vertically extending
wall 9. According to various exemplary embodiments, the toilet 10 may be formed from
vitreous china, porcelain, stainless steel, or any suitable material.
100341 According to an exemplary embodiment, the toilet 10 includes a bowl I4 (e.g., a toilet
25 bowl) configured to house water and waste, a rim channel 54 that is provided above the bowl 14,
a water supply hole 44 that is fluidly connected to the rim channel 54, and a trapway 50 that is
fluidly connected to the bowl 14. The water supply hole 44 is configured to receive a supply of
water from a source and direct the water to tlie rim channel 54. The rim channel 54 directs the
water into the bowl 14, such as through various openings in the rim channel 54. The water and
waste are transferred from the bowl 14 and out of the toilet 10 through the trapway 50 during a
flush cycle.
5 100351 The toilet 10 may include a lid, a seat, both a lid and a seat, or other attachments
pivotally coupled to the toilet 10. As shown in FIG. I, the toilet 10 includes an attachment 70,
such as a lid attachment, that is coupled to a top surface 18 (shown in FIG. 2) ofthe toilet 10. In
other exemplary embodiments, the attachment 70 ofthe toilet 10 may alternatively or
additionally include a seat attachment and/or a bidet attachment.
10 100361 The toilet I0 may include a sliroud 24 that surrounds a portion of the toilet 10. As
shown in Figure 6, the shroud 24 surrounds at least a portion of the bowl 14. The shroud 24 may
have a curved outer surface that is generally concave, and curves inwardly toward a bowl I4 of
the toilet 10. The shroud 24 may be integrally formed with the bowl 14 proximate the top
surface 18 of the toilet 10. The concavity ofthe shroud 24 may increase the amount of space in
15 which a person iuay reach underneath a toilet, mopisweep underneath a toilet, etc. I'he shroud
24 may also define the amount of clearance space between the toilet I0 and a floor when the
toilet 10 is installed on a wall. Therefore, the shroud 24 may be configured to increase tlie
amount of space available to clean underneath and around the toilet 10. The shroud 24 may have
other suitable configurations (e.g., shapes, sizes, etc.). For example, the shroud may a convex
20 curved outer surfacc. As another example, the shroud may have a generally flat outer surface.
10037) The toilet 10 may include a pocket, such as a side pocket 22 providcd in the shroud of
the toilet. For example, the toilet 10 may includc two sidc pockets 22, where one side pocket 22
may be disposed on each ofa left side and a right side of the toilet 10. FIGS. 1-4 illustrate the
left-side pocket 22, and the right-side pocket may be configured generally symmetrically
25 opposite to the left-side pocket or may he configured differently than the left-side pockct 22. As
viewed from either the left or the right side of the toilet 10, and as shown in FIG. 4, the side
pocltets 22 may be dcfincd on a rear side by a rear ~nountingw all 12, and on a front side by a
bowl 14 and/or the shroud 24. As shown in FIG. 3, the side pockets 22 may also be defined by
an interior end side, which may separate the side pockets 22 fiom the bowl 14 and a trapway 50.
It is noted that the pocket(s), such as the pocket 22, is optional on the toilet 10. Although, the
toilet not having a pockct may require external routing of the features, such as the water line
andlor electrical cord, which is not as advantageous as routing such features internally to the
5 toilet, such as for aesthetics, cleanability, functionality, and other reasons. However, routing
such features externally to the toilet may be easier for installation purposes.
[0038] As shown in FIG. 4, the toilet I0 is installed on (c.g., mounted to) the wall 9. The toilet
10 may include onc or more mounting holes 20 that are configured to facilitate mounting the
toilet 10 to the wall 9, such as, using one or more fasteners andlor threaded stud bolts. As shown
10 in FIG. 5, the toilet 10 includes two spaced-apart mounting holes 20 disposed in a mounting wall
12 ofthe toilet I0 in order to couple the mounting wall 12 (and the toilet 10) to the wall 9. The
mounting holes 20 may be defined on one side by either of the side pockets 22. The mounting
holes 20 may be disposed proximate to a top portion of tlie mounting wall 12, such as with one
~nountingh ole 20 on a left side of the mounting wall 12 and with another ~nountingh ole 20 on a
15 right side ofthe mounting wall 12.
100391 According to other embodiments, the mounting holes of the toilet may be arranged
within a mounting wall in a variety of ways that are configured to provide sufficient support for
the toilet when the toilet is installed on a wall. For example, the mounting holes may be centered
between left and right sides ofthe toilet proximate a bottom and top of a mounting wall. Also,
20 tlie mounting holes may be provided on left and right sides ofthe toilet proximate a bottom
portion ofthe mounting wall. Further, the mounting holes may be arranged as a combination of
any of the previously described arrangements.
[0040] The toilet I0 may be coupled to a wall (c.g., the wall 9) when the mounting holcs 20 are
rcceived, for cxample, by threaded stud bolts, which may extend into each side pockct 22. For
25 example, the threaded stud bolts may be coupled to the wall and extend through the mounting
holes 20 of the mounting wall 12 into the side pockets 22, whereby additional fasteners are used
within each side pocket to fasten to the bolts to secure the toilet 10 to the wall. Fasteners may
then be used on tlie threaded stud bolts within each side pocket 22 to fasten the toilet to the wall.
According to an exemplary ernbodimelit, the side pockets 22 !nay be configured to enable a user
to inore easily install the toilet I0 to the wall 9. For example, the height and width of an opening
of the side pockets 22 {nay be sufficiently large for a human hand to be received therein, in order
for a person to easily access the fastener in the pocket 22 to couple the toilet 10 to a wall using
5 the fastener. Therefore, the side pockets 22 may be configured to receive a human hand in order
to facilitate the installation of thc toilet 10 onto a wall.
[0041] The toilet 10 may include a cover that is configured to cover the side pockets 22. As
shown in FIG. 2, a relnovable cover 28 may be detachably coupled to the toilet 10, such as one
of the side pockets 22, in order to cover the respective side pocket. Each side pocket 22 ofthe
ro toilet 10 may be covered by a re~novablec over 28 in order to advantageo~~silmy prove the
aesthetics ofthe toilet when covering the pocket while providing the utility of access to the
pocket when removed from covering the pocket. For example, the outer surface of each side
pocket 22 may be recessed relative to the shroud 24, such that when the re~novablec over 28 is
coupled to the toilet 10, an exterior (e.g., outer) surface 28a of each removable cover 28 is flush
15 with the shroud 24. In turn, the exterior surface of each removable cover 28 may be configured
to complement an exterior surface of the shroud 24, such as the curvature of the shroud 24 when
each removable cover 28 is coupled to the toilet 10 covering the respective side pocket 22.
[0042] According to an exemplary embodiment, each removable cover 28 may be re~novably
coupled to a side pocket 22. For example, an inner side of each re~novablec over 28 may include
20 a plurality oftlexible clips, which may be configured to relnovably couple to a plurality ofsidcs
ofthe respective sidc pocket 22. Also, for cxample, a listener, such as hook and loop fastener
tape, may bc used on each of an inner surhce of thc removable covers 28 and the outer surface
of the side pockets 22 to detachably couple the cover 28 to the side pocket 22. It should bc
understood that the removable covers 28 may bc coupled to the side pockets 22 of the toilet 10 in
25 otlier suitable ways.
[0043] According to another exemplary embodiment, each side pocket 22 of the toilet 10 may
include a cover that is hinged on one side. The hinged side of the cover may be coupled to a side
of the toilet, and the cover may pivot bctween closed and open positions, such as to conceal or
provide access to the side pocket 22.
[0044] Advantageously, the removable covers 28 may conceal the side pockets 22, as well as
any fasteners used to install the toilet 10 to a wall, from view. Further, the removable covers 28
5 may advantageously prevent the side pockets 22 from accumulating dirt and other contaminants.
Thus, toilct 10 may be easier to clean and maintain with the covers 28 in place.
[0045] As shown in FIG. 3, the bowl 14 of the toilet I0 is positioned forward of the side
pockets 22 and the mounting wall 12 (see, e.g., FIG. 4) when the toilet 10 is installed on a wall.
The bowl 14 may define an opening 16 within the top surface 18. As shown in FIG. 3, the bowl
l o 14 and the opening 16 may be generally oval-shaped. In otlier cnibodirnents, the bowl 14 and
the opening I6 may be generally circular, elongated, or have any other suitable shape.
[0046] As shown in FIG. 4, the toilet 10 includes a side pocket hole 26 that is disposed within
the inner side ofeach side pocket 22. Each side pocket hole 26 may extend Srom the respective
side pocket 22 on a first side to a space (the space is between the bowl 14 and the mounting wall
15 12) on a second side. The side pocket hole 26 may be configured to receive either of an
electrical cord, a water supply line, both an electrical cord and a water supply line, or any other
suitable cordllinelhose for a toilet attachment or accessory. As shown in FIG. 4, the side pocket
hole 26 is a generally circular hole. According to other exemplary embodiments, the shape of
the side pocket hole 26 may be oval, rectangular, or any other suitable shape, which may, for
20 example, allow routing of another element (e.g., electrical cord, water line, etc.) through the side
pocket hole 26 of the toilet 10.
100471 As shown in FIGS. 4-6, the mounting wall 12 ofthe toilet 10 is locatcd rearward of the
side pockcts 22 and the bowl 14. Also, thc mounting wall 12 may be integrally formed with the
bowl 14 and the side pockets 22. The rnounting wall 12 may include a rear surface 12a that is
25 generally planar. The rcar surface 12a of the mounting wall I2 is configured to face a wall when
the toilet 10 is installed thereon.
[0048] The toilet may include additional holes. As shown in FIG. 5, in addition to the
mounting holes 20, a clearance hole 30 is disposcd within a portion of each ofthc lefl and right
sides of the mouliting wall 12. According to an cxe~nplaryc nibodiment, the clearance holes 30
are also disposed within the rear side of each side pocket 22. As shown in FIG. 5, each clearance
5 hole 30 is positioned below eithcr of the mounting holes 20, and each clearance hole 30 is
elongated vertically. According to other embodiments, the clearance holes may be positioned
above the mounting holes 20, or on another side relative to the mounting holcs 20. Further, the
present disclosure is not intended to limit the size, shape, or geometry of the clearance holes 30.
In addition, each clearance hole 30 is configured to receive an electrical cord, a water supply
l o line, both an electrical cord and a water supply line, or any other suitable cord/liiie/hose for a
toilet attachment or accessory.
[0049] The toilet 10 may include a trapway 50 to transfer water and waste from the bowl 14
and out ofthe toilet 10. As shown in FIGS. 5 and 6, the trapway 50 is provided on the rcar side
of the bowl 14, and includes an inlet 50a and an outlet 50b. The inlet 50a ofthe trapway 50 is
I5 fluidly connected to the bowl 14 and the outlet 50b extends through a portion of the rear
mounting wall 12. The trapway 50 may be centered horizontally between a left and right side of
the toilet 10. such as between the clearance holes 30. The trapway 50 may be positioned
vertically above a lower portion 12b of the mounting wall 12 and below a water supply hole 44.
The outlet 50b of the trapway 50 is configured to be coupled to a drain pipe (i.e., a sewer pipe
20 which is not shown) in order to evacuate water and waste from the bowl I4 into the drain pipe.
[0050] FIGS. 5 and 6 also illustrate an exeniplary elnbodiment oftlie water supply hole 44 that
is provided near a top portion. such as the top surface 18, of t11c toilet 10. The water supply hole
44 may be configured to bc coupled to a supply line (not shown) that supplies water to the toilet
10. The supply line may he provided, for cxample, within the wall that the toilet 10 rnay be
25 installed to. The toilet 10 may include a flush valve configured to regulate the arnount of water
that is provided by the supply line to the water supply Iiolc 44 for a flushing cycle. For example,
an in-wall tank may be positioned within the wall, and a flush valve may be used to control the
amount of water that is supplied by the tank to the water supply hole 44. As another example, a
flush valve may be configured to be coupled directly between a watcr supply and the water
supply hole 44. Such a flush valve rnay regulate the amount of water provided to the water
supply hole 44 during a flushing cycle. It should be understood that other devices may be used
to provide water to the water supply hole 44 of the toilet 10. For example, the tank may be
5 external to the wall to which the toilet 10 is attached. The tank may also be internal or external
to the toilet, as well as the wall to which the toilet 10 is attached.
[0051] As shown in FIG. 6, the water supply hole 44 rnay be defined at a first end by a rear
opening 46, and at a second end by an opening 47 within the rim channel 54. The rear opening
46 of the water supply hole 44 may be generally co-planar with the mounting wall 12, and the
l o second end positioned near a rearward portion of the bowl 14, within the rim channel 54. As
shown in FIG. 6, there are a plurality of steps 45 along the length ofthe water supply hole 44,
and the diameter of each step decreases from the rear opening 46 to the rim channel 54.
According to other exemplary emboditnents, the water supply hole 44 may be configured to
decrease in diameter from the rear opening 46 to the rim channel 54 (e.g., the water supply hole
15 may be tapered, etc.). The reduction in diameter of the water supply hole 44 may
advantageously increase the water pressure of water flowing therethrougli, thereby increasing the
kinetic energy of water flowing therethrough. This arrangement may improve cleaning the bowl
by increasing the pressure of the water delivered to the bowl, such as from the rim channel.
[0052] As shown in FIGS. 6-7, according to an exemplary embodiment, an angled slot 48 is
20 disposed within a rear portion of the rim channel 54. An axis "A" may be defincd by the bore of
the angled slot 48, and as shown in FIG. 6, where the axis A is generally directed toward an entry
for the trapway 50. According to an exemplary embodiment, the anglcd slot 48 is configured to
dispense water toward the inlet 50a of'the trapway 50.
[0053] The arrangement of the angled slot 48 and the rim channel 54 may advantageously be
25 configured to conserve the hydraulic power of water that is supplied to the rim channel 54 by the
water supply hole 44. For example, the angled slot 48 is configured so that watcr pressurc and
gravity co~iiplernentarily act on water dispensed therefrom (i.e., water pressure acts in a first
direction parallel to thc axis A and gravity acts in the vertical portion ofthe first direction).
When watcr pressure and gravity co~nplementarily act on water that is dispensed through a hole,
hydraulic power is conserved. In contrast, when water pressure and gravity do not
complementarily act on water dispensed through a water, energy is lost as gravity alters the
direction of the water dispensed (i.e., from an essentially horizontal direction to an essentially
5 vertical direction). When the hydraulic power of water supplied to the bowl 14 and the trapway
50 is conservcd, there is more available energy that may be used to evacuate the bowl 14 and the
trapway 50. As the amount of energy that is available to evacuate the bowl 14 and the trapway
50 increases, the effectiveness of the flushing cycle increases. Therefore, in contrast to a rim
hole for a toilet that dispenses water in a generally horizontal direction, the angled slot 48 is
10 configured to more effectively evacuate waste from the bowl 14 and the trapway 50.
[0054] According to various exemplary embodiments, an angle of the axis A, relative to a
vertically downward direction, may be between approximately 15" and 60" (i.e., fifteen to sixty
degrees) when the toilet 10 is operably mounted. More preferably, the angle of the axis A,
relative to a vertically downward direction, may be between approximately 20" and 50" (i.e.,
15 twenty to fifiy degrees) when the toilet I0 is operably mounted. Even more preferably, the angle
of the axis A, relative to a vertically downward direction, may be approximately 25" (i.c.,
twenty-five degrees) when the toilet 10 is operably mounted.
[0055] As shown in cross-section of FIG. 7, according to an exemplary embodiment, the
angled slot 48 may be generally oval-shaped that is elongated in a side-to-side direction.
20 According to other exemplary embodiments, the cross-section of'the aliglcd slot 48 may he
circular, rectangular, elongated in a fore-and-aft direction, or any other suitable shape. The
cross-section of the angled slot 48 may be smaller in surface area than the cross-section of the
rear opening 46. This arrangement may advantageously increase the water flow (e.g., velocity,
pressurc).
25 [0056] As shown in FIG. 7, the toilet I0 includes a rim channel 54, which is positioned along
an upper portion of the bowl 14, and extends along the perimeter of the bowl 14. The rim
channel 54 is fluidly coupled to the watcr supply hole 44, and as shown in FIG. 7, branches off to
the left and right from the front opening (e.g., the opening 47) of the water supply hole 44. The
rim channel may be fluidly coupled to a separate water supply from the water supply that
supplies the slot 48. The rim channel 54 is configured to channel (e.g., direct) water from the
water supply hole 44 to a plurality of rim lioles 62,64, which arc disposed around the rim
channel 54. The rim holes 62,64 may be disposed in a linear lower surface of the rim
5 channel 54.
[0057] According to an exemplary embodiment, the plurality of rim holes 62,64 includes holes
of different sizes. The different sized holes may be disposed within the rim channel 54 in, for
example, an alternating arrangement (e.g., an arrangement in which smaller diameter holes, such
as the rim holes 62, alternate with larger diameter holes, such as the rim holes 64). The
lo alternating arrangement of rim holes 62, 64 may advantageously generate a swirling effect (e.g.,
a cyclone effect, vortex effect, etc.) of water along the surhce of the bowl 14, when water flows
therethrough. As shown in FIG. 7, the plurality of rim holes may include several larger holes 64
with the remaining holes being smaller holes 62.
[0058] The rim channel 54 of the toilet 10 may include a rim slot 66. The rim slot 66 may be
i s disposed within thc bottom surface of the rim channel 54 (see FIG. 7), proximate a front-left
portion of the rim channel 54. The length of the rim slot 66 is greater along the length ofthe rim
channel 54 than the width of the rim channel 54. As shown, the rim slot 66 may be larger than
the other rim holes 62,64. According to another exemplary embodiment, the rim slot 66 {nay be
disposed on a front-right portion of the rim channel 54. Further, the rim slot 66 may
20 advantageously help generate a swirling effect of water along the surface of the bowl 14, when
water ilows through the rim slot 66. For example, the combination ofthe alternating
arrangement oi'rim holes 62, 64 and the rim slot 66 may be configured to generate a swirling
effect of water along the surface of the bowl 14, when water flows through the rim channel 54.
It should be understood that other arrangements of alternating lloles (i.e., a specific number of
25 alternating holes, the relative and specific size of alternating holes, etc.) may be used to tailor the
swirling effect of water along the surface of the bowl 14 of the toilet 10.
100591 By way of example, rim channels having a series of rim holes, such as the rim holes 62,
64 and the rim slot 66, may generate a swirling effect of the water, which may clean a greater
amount of the bowl 14 compared to toilets having ritn holes that are not configured to generate a
swirling effect of tlie water. For example, water that follows a pathway defined by a "swirling"
pattern may cover more surface area of the bowl 14 than water that follows a pathway that is
more direct from a rim hole of the rim channel. Water that covers more surface area of the bowl
5 14 may clean more waste offthe surface of the bowl 14. Therefore, an arrangement of rim holes
62,64 andlor a rim slot 66 that are configured to generate a swirling pattern of water across the
bowl 14 may clean more waste off the bowl 14 than a series of rim holes that are not configured
to generate a swirling effect of water.
[0060] The toilet 10 may include one or more lioles configured to facilitate mounting a toilet
l o attachment (e.g., a seat attachment, lid attachment, andlor bidet attachment) to the toilet 10. FlG.
8 illustrates a pair of spaced apart holes 36, which may be used to mount a toilet attachment,
such as the attachment 70. Each hole 36 may be disposed within the top surface 18 ofthe toilet
10, such that the toilet attachment may be coupled to the top surface 18 using a variety of
fasteners. The fasteners may extend into either of the side pockets 22, such as to provide a user
15 with access to the fasteners, where the removable covers 28, if provided, !nay conceal the
fasteners used to couple the toilet attachment lo the top surface 18 of the toilet 10.
[0061] FIG. 8 also illustrates an accessory hole 38 that is disposed within the top surface 18 of
the toilet 10. The accessory hole 38 extends fro~nth e top surface 18 on a first side to the space
40 within the vitreous (the space 40 is best illustrated, for example, in FIG. 6) on a second side.
20 AS shown, the space 40 is dcfined on a rear side by the mounting wall 12, on a front side by the
bowl 14, and on left and right sides by the side pockets 22. The trapway pipe 50 may also be
positioned within the space 40. As shown in FIG. 8, the shape of the accessory hole 38 is
oblong. However, it should be understood that the accessory hole 38 or other acccssory holes
may take on a variety of shapes and sizes.
25 100621 The accessory hole 38 may be configured to receivc an electrical cord andlor a supply
line. For example, a bidet attachment for the toilet 10 may typically include an electrical cord
and a supply line. 'Ihc bidct attachment may be coupled to the top surface 18 of the toilet 10,
such as using holcs 36, and the electrical cord andlor the supply line of the bidet attach~nentm ay
be ro~~tethdr ough the accessory hole 38. Thus, electric power andlor water may be routed from
a source through the toilet 10, such as the space 40 and the accessory hole 38, to the bidet
attachment. The accessory hole 38 may be positioned within the top surface 18 at a locatio~ith at
may be substantially below or adjacent to a location where the electrical cord and supply line are
5 coupled to the bidet attachment, when ihe bidet attachment is coupled to the toilet 10. This
arrangement may advantageously allow routing of the electric power and water to tlie bidet
attachment with the electrical cord and supply line hidden from view, such as from a user.
[0063] According to an exemplary embodiment, tlie toilet 10 is configured to substantially
contain (is., house, receive, hold, envelope, etc.) the electrical cord and supply line of the bidet
10 attachment, so that the electrical eord and supply line are ~ninimallyd isposed along an exterior
surface of the toilet 10. In other words, according to an exemplary embodiment, it is desired to
minimize the presence of the electrical cord and supply line of the bidet attachment outside the
toilet 10 when the bidet attachment is coupled thereto. To this end, the electrical eord and supply
line ofthe bidet attachment may be received within tlie accessory hole 38 and extend into the
15 space 40 when the bidet attachment is coupled to the toilet 10. Then, the electrical line and
supply line may each be routed within the space 40 to either of the side pocket holes 26 of the
respective side pockets 22. Tlie electrical line and supply line may each be received by either of
the side pocket holes 26, atid extend into the corresponding side pocket 22.
[0064] The electrical power supply and the water supply may be provided, for example, within
20 the wall 9 to which the toilet I0 is mounted to (e.g., installed on). The electrical power supply
and the water supply may also be configured to extend into either of tlie side pockets 22, after
having been extended throudi tlie wall and received by either of the clearance holes 30.
Accordingly, tlie electrical cord from the bidet attachment riiay be electrically coupled to an
electrical power supply within a first side pocltet 22, and the supply line may be fluidly coupled
25 to a water supply within a second side pocket 22. In this way, the electrical cord and supply line
of the bidet attachment are substantially contained withi11 an exterior surface of the toilet 10. In
other words, the electrical cord andlor the supply line may be partially or completely hidden
from view ofa user of the toilet 10.
(00651 According to another exemplary embodiment, the electrical powcr supply and the water
supply are each coupled to the bidet attachmelit on opposite sides of the toilet 10. For example,
the water supply may be introduced into the toilet 10 through one of the clearance holes 30 and
routed to the bidet attachment through the accessory hole 38; and the electrical power supply
5 may be introduced into the toilet 10 through another clearance hole 30 and routed to the bidet
attachment through a second accessory hole. The toilet 10 may include a valve to regulate the
flow of water, such as to the bowl andlor to a bidet attachment. For example, the portion ofthe
water supply line that is received within the side pocket 22 may include a valve to regulate the
flow of water that is dispensed therethrough.
10 (00661 Advautageously, an electrical cord and a water supply line used with a toilet attachment
or a toilet accessory may be self-contained so that these elements are not substantially positioned
along the exterior ofa toilet. Accordingly, the electrical cord and a water supply line are kept
out ofthe way so as not to interfere with cleaning around the toilet. Also, the toilet disclosed in
the various exemplary embodiments herein may protect pets that are prone to chew on electrical
15 cords. Also, the toilet disclosed in the various exemplary embodin~entsh erein prevents an
electrical cord and a water supply line of a bidet attachment from accumulating dust, urinc, and
other contaminants. The toilets disclosed herein may also have an improved aesthetics, since the
cords and lilies are hidden from view.
[0067] In another exemplary embodiment, a bidet attachment for a wall-hung toilet may
20 overhang at least one side of the top surface of thc toilet. According to this embodiment, an
accessory hole may be disposed near the upper side ofthe toilet, proximate where the bidet
attachment overhangs the side of the toilet. In this way, the electrical cord and supply line of the
bidet attachment may be routed through the accessory hole, a space within the vitreous, and
either of two side pocket holes to be received by either of two side pockets of the toilet.
25 Accordingly, ail electrical power supply and a water supply may be configured to extend into the
through the mounting wall, either of two clearance holes, and into either ofthe two side pockets
wherc thcy may be coupled to the electrical cord and supply line of the bidet attachment.
[0068] According to another exemplary embodiment, the electrical cord and water s~lpplyli ne
of a bidet attachment may be routed through a single rim hole, and couple to an clectrical power
s~~ppalnyd a water supply within a single sidc pocket ofthe toilct.
100691 According to yet another exetnplary embodiment, a wall-hung toilet may have a side
5 pocket on left and right sides of the toilet. According to this embodiment, each side pocket may
have an inner side that is not defined by an inner wall or an inner surface (is., the inner side of
thc side pocket is openly disposed). An exte~isionc ord or a water supply line of a bidet
attachment may be extend through an accessory hole disposed within a top surface of the toilet,
atid into a space between the mounting wall and the bowl. Then, the electrical cord may be
10 routed through the space and be received by either side pocket (the inner side of the side pocket
being openly disposed to the space). An electrical power supply and a water supply may be
provided in a wall, and extend through the wall. The electrical power supply and water supply
may extend through either of a clearance hole disposed within the mounting wall and into the
respective side pocket. Therefore, the extension cord and water supply line of the bidet
15 attachment may couple to the electrical power supply and water supply, respectively, within the
side pocket.
100701 According to various embodiments ofthis disclosurc, other electrical cords and fluid
conduits may be reccived by an accessory hole disposed within a top surface of a toilet. For
example, an electrical cord for a heated seat attachmcnt, an illuminated seat attachme~itllid
20 atlachmcnt, or an electric motor configured to raise and lower a seat attachmcntiiid attachment,
etc. may be received by an accessory hole.
