The present disclosure relates to a toilet bowl of a toilet arrangement. More particularly, the present invention relates to a toilet rim for the toilet bowl of the toilet arrangement.
BACKGROUND
This section is intended to provide information relating to the field of the invention and thus any approach or functionality described below should not be assumed to be qualified as prior art merely by its inclusion in this section.
Toilet arrangements are known in sanitation industry, to enable persons to defecate in good sanitary conditions. A typical toilet arrangement includes a toilet bowl (also referred to as a 'water closet', interchangeably hereinafter) and a flush arrangement. The toilet bowl is provided to receive faecal matter, when a user performs defecation thereon. The flush arrangement includes a flush tank and a flush valve unit. The flush tank stores water therein. The flush valve unit is fluidly connected between the flush tank and the toilet bowl, to allow/restrict a supply of water from the flush tank to the toilet bowl, upon actuation/release of at least one flush button. This results in flushing of faecal matter therefrom.
The toilet bowl includes a toilet base bowl and a toilet rim. The toilet base bowl is formed of ceramic material, including a lower portion and an upper portion. The lower portion is shaped in form of a bowl, while the upper portion is shaped in form of an oval-shaped peripheral structure, which support the person while defaecating. Further, the toilet rim is arranged within the upper portion of the toilet base bowl, such that the toilet rim receives water from the flush tank, and distribute the same in the toilet base bowl, for flushing.

Conventionally, the toilet rim includes an oval-shaped closed loop tubular structure, and a plurality of outlet conduits extending perpendicularly downwards from the oval-shaped closed loop tubular structure towards the toilet base bowl. Further, the oval-shaped closed loop tubular structure is fluidly connected to the flush arrangement, to receive water therefrom. In particular, the oval-shaped closed loop tubular structure includes a T-joint fluidly connected with a supply pipe extending from the flush arrangement. Accordingly, water as received from the flush arrangement, is divided in two streams of water in the oval-shaped closed loop tubular structure, which is released through the plurality of outlet conduits to the toilet bowl. This reduces a water pressure released from the toilet rim to the toilet base bowl, thus requiring more water to perform flushing. Further, in conventional toilet rims, the plurality of outlet conduits extend perpendicularly downwards from the oval-shaped closed loop tubular structure. This results in release of water from the toilet rim to the toilet base bowl in a relatively turbulent manner, which may further cause requirement of relatively more water to perform flushing. Also, a flow velocity of water in the oval-shaped closed loop tubular structure reduces drastically between the T-joint and the point of meeting of the two streams of water, in particular, a flow velocity of water at a position in proximity of the T-joint is more than a flow velocity of water at a position of meeting of the two streams of water. This results in loss of potential energy of water, thus requiring more water for flushing.
Accordingly, in light of the aforementioned drawbacks and several other inherent in the existing arts, there is a well felt need to provide a toilet bowl of a toilet arrangement that uses relatively less water for flushing purposes.
SUMMARY
This section is intended to introduce certain objects of the disclosed method and system in a simplified form, and is not intended to identify the key advantages or features of the present disclosure.

It is an object of the present invention to provide a toilet bowl of a toilet arrangement. The toilet bowl comprises a toilet base bowl and a toilet rim.

DETAILED DESCRIPTION
In the following description, for the purposes of explanation, various specific details are set forth in order to provide a thorough understanding of embodiments of the present invention. It will be apparent, however, that embodiments of the present invention may be practiced without these specific details. Several features described hereafter can each be used independently of one another or with any combination of other features. An individual feature may not address any of the problems discussed above or might address only one of the problems discussed above. Some of the problems discussed above might not be fully addressed by any of the features described herein. Example embodiments of the present invention are described below, as illustrated in various drawings in which like reference numerals refer to the same parts throughout the different drawings.
Figure 1 shows a perspective view of a toilet arrangement [100], in accordance with the concepts of the present disclosure. The toilet arrangement [100] facilitates a person to defecate in good sanitary conditions. The toilet arrangement [100] is generally known to include a toilet bowl [102] and a flush arrangement [104].

The toilet bowl [102] is a bowl structure, which is provided to receive faecal matter, when a user performs defecation thereon. Details of structure and arrangement of the toilet bowl [102], will be explained later in details.
The flush arrangement [104] is provided to supply water to the toilet bowl [102], for flushing faecal matter therefrom. The flush arrangement [104] includes a flush tank [106] and a flush valve unit. The flush tank [106] is adapted to store water therein. Further, the flush tank [106] of the flush arrangement [104] is fluidly connected to the toilet bowl [102] with use of a supply pipe [110]. The flush valve unit is positioned within the supply pipe [110], and is adapted to allow/restrict the supply of water from the flush tank [106] of the flush arrangement [104] to the toilet bowl [102]. In particular, the flush valve unit allows/restrict the supply of water from the flush tank [106] of the flush arrangement [104] to the toilet bowl [102], upon actuation/release of at least one flush button [112]. Flushing is enabled in the toilet bowl [102], corresponding to the supply of water from the flush tank [106] of the flush arrangement [104] to the toilet bowl [102]. Although, the present disclosure describes the toilet arrangement [100] as a tank-based toilet arrangement, it may be obvious to a person ordinarily skilled in the art that the toilet arrangement [100] can also be an in-line toilet arrangement. A structure and arrangement of the toilet bowl [102] will be explained in details hereinafter.
Figure 1 shows a perspective view of a toilet arrangement [100], in accordance with the concept of the present disclosure. Figure 2 shows a top view of the toilet bowl [102] of the toilet arrangement [100], in accordance with the concepts of the present disclosure. Figure 1 and Figure 2 should be referred to in conjunction with each other in order to clearly understand the concepts of the present disclosure related to the toilet bowl [102]. The toilet bowl [102] includes a toilet base bowl [114] and a toilet rim [116]. In a second embodiment of the toilet bowl [102], each of the toilet base bowl [114] and the toilet rim [116] are formed as separate components, and further connected

together to form the toilet bowl [102]. In a first embodiment of the toilet bowl [102], each of the toilet base bowl [114] and the toilet rim [116] are integrally formed as a singular integrated component. Both the embodiments are within a scope of the present disclosure.
Concept in respect of the first embodiment of the toilet bowl [102], will be explained hereinafter. In the first embodiment of the toilet bowl [102], the toilet base bowl [114] and the toilet rim [116] are integrally formed. In the first embodiment, each of the toilet base bowl [114] and the toilet rim [116] are formed of ceramic material. Notably, in such embodiment, the toilet base bowl [114] and the toilet rim [116] are formed by casting in a single casting machine. The toilet base bowl [114] includes a lower portion [114a] and an upper portion [114b]. The toilet rim [116] is arranged with the upper portion [114b] of the toilet base bowl [114], and is adapted to distribute water as received from the flushing arrangement [104], within the toilet base bowl [114], for enabling flushing of faecal matter therefrom.
Figure 3 is a top view of the toilet rim [116] of the toilet bowl [102], in accordance with the concepts of the first embodiment of the toilet bowl [102] disclosed in the present disclosure. Figure 4 is a side view of the toilet rim [116] of the toilet bowl [102], in accordance with the concepts of the first embodiment of the toilet bowl [102] disclosed in the present disclosure. Figure 3 and figure 4 should be referred to, in conjunction with each other, in order to clearly understand concepts of the present disclosure with respect to the first embodiment of the toilet rim [116]. Although, figure 3 and figure 4, for illustrative purposes, shows the toilet rim [116] as a separate component, it may be obvious to a person ordinarily skilled in the art that the toilet rim [116] is the integral component of the toilet bowl [102], in accordance with the first embodiment of the toilet bowl [102]. In particular, the toilet rim [116] includes a tubular structure [118] and a plurality of outlet conduits [120].

The tubular structure [118] is provided in form of a singular tubular structure, suitably bent to form an oval-structured unit, in particular an open-looped oval-structure unit, conforming to the upper portion of the toilet base bowl [114]. Although, the present disclosure is explained as the tubular structure [118] being deployed as the open-looped oval-structure unit, it may be obvious to a person ordinarily skilled in the art that the tubular structure [118] can also be deployed as an open-looped square structured unit, and/or an open-looped circular structured unit, depending on a shape of the upper portion [114b] of the toilet base bowl [114]. The tubular structure [118] defines a first end [118a], a second end [118b], and a middle section [118c] defined therebetween. The first end [118a] of the tubular structure [118] is fluidly connected to the supply pipe [110] of the flushing arrangement [104], to receive water therefrom. Further, the second end [118b] of the tubular structure [118] is closed. With such arrangement, the tubular structure [118] is capable of receiving water through the first end [118a], to be flown in a water flow direction towards the second end [118b] through the middle section [118c]. Furthermore, the tubular structure [118] is sequentially divided into four sections, namely a first section [118e], a second section [118f], a third section [118g], and a fourth section [118h], in the water flow direction. Notably, the first section [118e] includes the first end [118a], and the fourth section [118h] includes the second end [118b]. An interior of the tubular structure [118] has a cross-section area that decreases continuously from the first end [118a] to the second end [118b] in the water flow direction. Notably, the interior of at least one portion of the tubular structure [118] has an elliptical cross-section area. This allows a smooth and laminar flow of water within the tubular structure [118], while flowing from the first end [118a] to the second end [118b] in the water flow direction. In particular, the cross-sectional area of the at an end of the first section [118e] in the water flow direction, is 50% of a cross-section area at the first end [118a] defined by the first section [118e] of the tubular structure [118]. Moreover, a cross-section area at an end of the second section [118f] in the water flow direction, is 36% of the cross-section area at the first end [118a] defined by the first
section M 1 8el nf the tubular structure M 181 Moreover a rrnss-sertinn area at an end

of the third section [118g] in the water flow direction, is 25% of the cross-section area of the first end [118a] defined by the first section [118e] of the tubular structure [118]. Furthermore, a cross-section area at the second end [118b] defined by the fourth section [118h] of the tubular structure in the water flow direction, is 9.5% of the cross-section area of the first end [118a] defined by the first section [118e] of the tubular structure [118]. It may also be noted that the cross-section of the tubular structure [118] decreases continuously from the first end [118a] to the second end [118b], in particular, the cross-section of the tubular structure [118] decreases continuously between the first section [118e], the second section [118f], the third section [118g], and the fourth section [118h]. This results in positioning of the first end [118a] of the tubular structure [118] at a relatively higher height than the second end [118b] of the tubular structure [118].
The plurality of outlet conduits [120] are adapted to release water received in the tubular structure [118] to the toilet base bowl [114], forflushing. The plurality of outlet conduits [120] are relatively small conduit pipes extending from the middle section [118c] directed towards an interior of the toilet base bowl [114]. The plurality of outlet conduits [120] are angled at an acute angle relative to the water flow direction. As the plurality of outlet conduits [120] are angled at an acute angle, the plurality of outlet conduits [120] allow exit of water to an interior of the toilet base bowl [114], in a swirl-flow manner. Such exit of water to the interior of the toilet base bowl [114] in the swirl-flow manner, requires relatively less water for flushing the faecal matter from the toilet base bowl [114].
Concepts in accordance with the second embodiment of the toilet bowl [102], will be explained in detail hereinafter. Figure 5 is a top view of a schematic of the toilet bowl [102], in accordance with the concepts of the second embodiment of the toilet bowl [102] disclosed in the present disclosure. Figure 6 is a side view of a schematic of the toilet bowl [102], in accordance with the concepts of the second embodiment of the

toilet bowl [102] disclosed in the present disclosure. Figure 7 shows an isometric view of a portion of a schematic of the toilet bowl [102], in accordance with the second embodiment of the toilet bowl [102]. Figure 5, figure 6, and figure 7, should be referred to in conjunction with each other, in order to clearly understand the concepts of the second embodiment of the toilet bowl [102] disclosed in the present disclosure. In the second embodiment of the toilet bowl [102], the toilet base bowl [114'] and the toilet rim [116'] are separately formed. In the second embodiment of the toilet bowl [102], the toilet base bowl [114'] is formed of a ceramic material, while the toilet rim [116'] is at least partially formed of a elastomer material.
A structure and arrangement of the toilet base bowl [114'] in accordance with the second embodiment of the toilet bowl [102], is similar to a structure and arrangement of the toilet base bowl [114'] in accordance with the first embodiment of the toilet bowl [102]. Particularly, the toilet base bowl [114'] includes a lower portion [114a'] and an upper portion [114b']. In one embodiment, the upper portion [114a'] forms a step relative to the lower portion [114b'] of the toilet base bowl [114']. In another embodiment, the upper portion [114a'] forms a U-shaped cavity [114d'] therein. Concepts of the present disclosure hereinafter, will be explained in relation to mounting of the toilet rim [116'], in the U-shaped cavity [114d'] in the upper portion [114a'] of the toilet base bowl [114']. Similar concepts of the present disclosure may be envisioned to be applied in relation to mounting of the toilet rim [116'], on the step of the upper portion [114a'] of the toilet base bowl [114'].
The toilet rim [116'] is at least partially formed of a elastomer material, and is positioned within the U-shaped cavity [114d'] formed in the upper portion [114a'] of the toilet base bowl [114']. The toilet rim [116'] includes a tubular structure [118'], a connection adapter [119'], and a plurality of outlet conduits [120'].

The tubular structure [118'] is formed of a soft elastomer material, such as but not limited to, thermoplastic elastomer (TPE), rubber, EVA (Elastic Plastic), foam, and the like. The tubular structure [118'] is provided in form of a singular tubular structure, suitably bent to form an oval-structured unit, in particular an open-looped oval-structure unit, conforming to the upper portion of the toilet base bowl [114']. Although, the present disclosure is explained as the tubular structure [118'] being deployed as the open-looped oval-structure unit, it may be obvious to a person ordinarily skilled in the art that the tubular structure [118'] can also be deployed as an open-looped square structured unit, and/or an open-looped circular structured unit, depending on a shape of the upper portion [114b'] of the toilet base bowl [114']. The tubular structure [118'] defines a first end [118a'], a second end [118b'], and a middle section [118c'] defined therebetween. Further, the second end [118b'] of the tubular structure [118'] is closed. Furthermore, the tubular structure [118'] is sequentially divided into four sections, namely a first section [118e'], a second section [118f ], a third section [118g'], and a fourth section [118h'], in the water flow direction. Notably, the first section [118e'] includes the first end [118a'], and the fourth section [118h'] includes the second end [118b']. An interior of the tubular structure [118'] has a cross-section area that decreases continuously from the first end [118a'] to the second end [118b'] in the water flow direction. Notably, the interior of at least one portion of the tubular structure [118'] has an elliptical cross-section area. This allows a smooth and laminar flow of water within the tubular structure [118'], while flowing from the first end [118a'] to the second end [118b'] in the water flow direction. In particular, the cross-sectional area of the at an end of the first section [118e'] in the water flow direction, is 50% of a cross-section area at the first end [118a'] defined by the first section [118e'] of the tubular structure [118']. Moreover, a cross-section area at an end of the second section [118f ] in the water flow direction, is 36% of the cross-section area at the first end [118a'] defined by the first section [118e'] of the tubular structure [118']. Moreover, a cross-section area at an end of the third section [118g'] in the water flow direction, is
?,5% nf the rrnss-sertinn area nf the first end M 1 Ra'l defined hv the first section M 1 8e'l

of the tubular structure [118']. Furthermore, a cross-section area at the second end [118b'] defined by the fourth section [118h'] of the tubular structure in the water flow direction, is 9.5% of the cross-section area of the first end [118a'] defined by the first section [118e'] of the tubular structure [118']. It may also be noted that the cross-section of the tubular structure [118'] decreases continuously from the first end [118a'] to the second end [118b'], in particular, the cross-section of the tubular structure [118'] decreases continuously between the first section [118e'], the second section [118f ], the third section [118g'], and the fourth section [118h']. This results in positioning of the first end [118a'] of the tubular structure [118'] at a relatively higher height than the second end [118b'] of the tubular structure [118'].
The connection adapter [119'] is provided to fluidly couple the tubular structure [118'] to the supply pipe [110], and is made up of a relatively hard elastomer material, such as but not limited to, thermoplastic elastomer (TPE), rubber, EVA (Elastic Plastic), foam, and the like. For such purposes, the connection adapter [119'] is fluidly coupled to the first end [118a'] of the tubular structure [118']. Further, the connection adapter [119'] is also fluidly coupled to the supply pipe [110]. With such arrangement, the tubular structure [118'] is capable of receiving water through the connection adapter [119'] at the first end [118a'], to be flown in a water flow direction towards the second end [118b'] through the middle section [118c'].
The plurality of outlet conduits [120'] are adapted to release water received in the tubular structure [118'] to the toilet base bowl [114'], for flushing. The plurality of outlet conduits [120'] are relatively small conduit pipes extending from the middle section [118c'] directed towards an interior of the toilet base bowl [114']. The plurality of outlet conduits [120'] are angled at an acute angle relative to the water flow direction. As the plurality of outlet conduits [120'] are angled at an acute angle, the plurality of outlet conduits [120'] allow exit of water to an interior of the toilet base bowl [114'], in a swirl-flow manner. Such exit of water to the interior of the toilet base

bowl [114'] in the swirl-flow manner, requires relatively less water for flushing the faecal matter from the toilet base bowl [114']. For attachment of the toilet rim [116'] to the toilet base bowl [114'], the tubular structure [118'] of the toilet rim [116'] is attached within the U-shaped cavity [114d'] formed within the upper portion [114b'] of the toilet base bowl [114']. The tubular structure [118'] of the toilet rim [116'] is attached within the U-shaped cavity [114d'] formed within the upper portion [114b'] of the toilet base bowl [114'], via an attachment means. The attachment means includes, but is not limited to, an adhesive attachment, a C-clip attachment, a plastic attachment, a bolt attachment, and/or any other similar attachment means. With such arrangement, the tubular structure [118'] is capable of receiving water through the connection adapter [119'] at the first end [118a'] of the tubular structure [118'], to be flown in a water flow direction towards the second end [118b'], and further exit the water to the interior of the toilet base bowl [114'] through the plurality of outlet conduits [120'].
Various advantages of the toilet bowl [102], as disclosed in the present disclosure, exists. For example, as the plurality of outlet conduits [120, 120'] of the toilet rim [116, 116'] of the toilet bowl [102] are angled at an acute angle, the plurality of outlet conduits [120, 120'] allow exit of water to an interior of the toilet base bowl [114, 114'], in a swirl-flow manner. Such exit of water to the interior of the toilet base bowl [114, 114'] in the swirl-flow manner, requires relatively less water for flushing the faecal matter from the toilet base bowl [114, 114']. Additionally, such exit of water to the interior of the toilet base bowl [114, 114'] in the swirl-flow manner, causes a relatively more coverage of flush area within the interior of the toilet base bowl [114, 114'], and thus causing better cleaning. Another advantage of the present disclosure relates to water attachment of the tubular structure [118, 118'] at the first end [118a, 118a'], and the second end [118b, 118b'] being closed. This enables flow of water only in one direction forming only one stream of water, instead of the T-joint. This avoids any backflow or cancellation of flow of water, thus saving a kinetic energy of water,

and consequently requiring less water for flushing operations. Yet another advantage of the toilet bowl [102], as disclosed in the present disclosure, relates to the first end [118a, 118a'] of the tubular structure [118, 118'] been placed at a relatively higher height than the second end [118b, 118b'] of the tubular structure [118, 118']. This results in a relatively increased average velocity of water exiting from the tubular structure [118, 118'] of the toilet rim [116, 116'] to the toilet base bowl [114, 114'], thus requiring relatively less water, for flushing operations. Yet another advantage of the present disclosure relates to the continuously decreasing cross-section of the tubular structure [118, 118'] between the first section [118e, 118e'], the second section [118f, 118f ], the third section [118g, 118g'], and the fourth section [118h, 118h']. This facilitates in gradual decrease in average velocity of water flowing in the tubular structure [118, 118']. Thus, the kinetic energy of the water flowing in the tubular structure [118, 118'] is conserved, and adds to low requirements of water for flushing purposes. As the interior of at least one portion of the tubular structure [118, 118'] has an elliptical cross-section area, it allows a smooth and laminar flow of water within the tubular structure [118, 118'], while flowing from the first end [118a, 118a'] to the second end [118b, 118b'] in the water flow direction. Overall, the specific design, structure, and arrangement of the toilet rim [116, 116'] of the toilet bowl [102], as disclosed in the present disclosure, requires relatively less water, for flushing purposes.
Although particular embodiments have been disclosed herein in detail, this is for illustrative purposes only and is not intended in any way to limit the intended scope of the invention, variations and adaptions of the system and method as described herein that do not depart from the spirit and scope of the invention and within the expertise of a person skilled in the art.
