Specification

Description:FIELD OF THE INVENTION

The present disclosure relates to a water guide. More particularly, the present disclosure relates to the water guide for a washing machine to generate air bubbles during washing of a laundry.

BACKGROUND

In washing machines, sometimes air bubbles are generated during a wash cycle that can help to remove dirt and other particles from laundry, allowing them to be carried away more easily by water. When water is agitated by an agitator in a washing machine, air bubbles are created that collapse when they come in contact with the laundry thereby, generating tiny shock waves that can help to loosen dirt and grime from the laundry.

Additionally, the air bubbles help to emulsify oil and greasy substances on the surface of fabrics, making them easier to remove during the washing process. Further, during the rinse cycle of the washing machine, the air bubbles can help to remove detergent and dirt particles from the fabric, thereby ensuring that clothes come out of the wash feeling clean and fresh.

However, the air bubbles are not generated consistently in the washing machine during the wash cycle. There may be several reasons for the inconsistent generation of the air bubbles. One important reason is that the washing machine is not designed to generate the air bubbles effectively and consistently, which impacts the cleaning performance of the washing machine.

Typically, conventional washing machines include a specialized component for generating the air bubbles. This specialized component works by spraying a water jet onto the detergent as it is added to the washing machine. The force of the water jet causes the detergent to froth, creating the air bubbles in the process. However, this method of generating air bubbles heavily relies on the use of the detergent. If a user decides not to use detergent or ends up using too little detergent, the generation of air bubbles can be inconsistent or non-existent. Additionally, this method may not be effective in producing a sufficient amount of air bubbles for optimal cleaning performance. In some cases, the generation of the air bubbles through this method can be slow, which can prolong the wash cycle and increase energy consumption. Furthermore, the specialized unit is a complex structure that is difficult to maintain.

Therefore, there is a requirement for a washing machine capable of generating air bubbles to overcome the abovementioned problems.

SUMMARY

This summary is provided to introduce a selection of concepts, in a simplified format, that are further described in the detailed description of the invention. This summary is neither intended to identify key or essential inventive concepts of the invention nor is it intended for determining the scope of the invention.

The present disclosure is a water guide for generating air bubbles. The water guide includes a front panel and a water conduit. The front panel has an inlet disposed at a bottom end of the front panel and an outlet disposed at a top end of the front panel. The inlet is adapted to receive water from a source. The water conduit is installed in the front panel. The water conduit is having a convergent portion, a throat region, and an air conduit. The convergent portion has a first end, a second end, and a body. The first end is adapted to receive the water from the inlet. The second end adapted to dispense the water. The body has a tapered profile between the first end to the second end. The throat region is fluidically connected to the second end and the outlet, adapted to create a negative pressure therein. The air conduit is disposed at the top end of the front panel, is fluidically connected to the throat region, and adapted to introduce air into the throat region upon application of the negative pressure. The throat region is adapted to mix air received from the air conduit and the water received from the second end for generating the air bubbles and dispensing the air bubbles from the outlet.

The present disclosure also relates to a washing machine having a wash tub, a pulsator, and a water guide. The wash tub is adapted to wash laundry with water and detergent. The pulsator is disposed at a bottom of the wash tub, adapted to agitate the detergent with the water and to propel the water radially outwardly. The water guide disposed on an inner side wall of the wash tub for generating the air bubbles. The water guide includes a front panel and a water conduit. The front panel has an inlet disposed proximate to the bottom of the wash tub and an outlet disposed proximate to a top of the wash tub. The inlet is adapted to receive the water propelled radially outwardly by the pulsator. The water conduit is installed in the front panel. The water conduit is having a convergent portion, a throat region, and an air conduit. The convergent portion has a first end, a second end, and a body. The first end is adapted to receive the water from the inlet. The second end adapted to dispense the water. The body has a tapered profile between the first end to the second end. The throat region is fluidically connected to the second end and the outlet, is adapted to create a negative pressure therein. The air conduit is disposed at the top end of the front panel, is fluidically connected to the throat region, and is adapted to introduce air into the throat region upon application of the negative pressure. The throat region is adapted to mix air received from the air conduit and the water received from the second end for generating the air bubbles and dispensing the air bubbles from the outlet into the wash tub.

According to the present disclosure, the water guide provides a simple and cost-effective way to generate the air bubbles in the washing machine. The addition of the air bubbles to the wash cycle can improve the cleaning performance of the washing machine, particularly for heavily soiled or stained clothes. Therefore, one may achieve better cleaning results by generating more air bubbles using the water guide. Further, by improving the cleaning performance of the washing machine, the water guide aids in the reduction of the amount of time needed for the wash cycle. This can be particularly beneficial for busy households or for those who need to do laundry frequently. This also aids in making the washing machine energy efficient with lower energy bills and a reduced environmental impact. In addition to improving energy efficiency, the use of air bubbles can also help in reducing water usage during the wash cycle. Further, the water guide is easy to assemble and disassemble and does not require the need of a skilled technician or complex machinery. Furthermore, the water guide equips the washing machine to provide an improved washing operation.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

Figure 1 illustrates a washing machine 100 having a water guide 101, according to an embodiment of the present disclosure. The washing machine 100 is capable of generating air bubbles with the help of the water guide 101.

The washing machine 100 can be semi-automatic, automatic top-loading. The washing machine 100 includes, but is not limited to, a wash tub 103 and a pulsator 102. The washing machine 100 uses an agitator, an impeller, or the pulsator 102 to move clothes around in the wash tub 103. A drive mechanism (not shown) is mounted at the bottom of the wash tub 103 that includes a drive motor 104 to rotate the pulsator 102.

In addition, the washing machine 100 may include a valve (not shown) adapted to receive a fresh water supply from a tap (not shown). The tap water is introduced to a detergent dispenser tray (not shown) from the valve, and the water is further dispatched to the wash tub 103 during a wash cycle.

The wash tub 103 receives the water and the detergent. The wash tub 103 is adapted to wash the clothes. The pulsator 102 is disposed at a bottom of the wash tub 103. The pulsator 102 is typically mounted in a center of the wash tub 103 and can be designed in a variety of shapes, such as a disk or a cone.

When washing machine 100 is in the wash cycle, the drive motor 104 oscillates the pulsator 102. The pulsator 102 is adapted to agitate the detergent with the water and to propel the water radially outwardly due to a centrifugal force being applied by the pulsator 102 with the help of the drive mechanism. As the pulsator 102 moves, it creates waves in the water that cause the clothes to move around which ensures that all areas of the clothes’ fabric come in contact with the detergent and water mixture.

The wash tub 103 has the water guide 101 provided in a part of an inner side wall of the wash tub 103. The water in the wash tub 103 is radially expelled by the pulsator 102 to partly flow into an inlet 203a formed at a bottom end of the water guide 101. As a result, a part of the water is circulated from the wash tub 103 through the water guide 101, and back to the inside of the wash tub 103 in form of the air bubbles. An outlet 202 formed at a top end of the water guide 101 is adapted to discharge the air bubbles back into the wash tub 103.

The air bubbles generated by the water guide 101 have several benefits. First, the air bubbles help to wash the clothes by better mixing with the dirt, thereby improving the cleaning performance. The air bubbles are created and collapsed during agitation, generating tiny shock waves that can help to loosen dirt and grime from clothes fibers. Secondly, the air bubbles help to soften the fabric and reduce wrinkles. Thirdly, when air is introduced into the water, it increases the amount of surface area available for contact between the water and the fabric being cleaned. This increased surface area can help to enhance the penetration of detergent into the clothes fibers, allowing for more effective removal of dirt and strains. Fourthly, the air bubbles help in emulsifying oil and greasy substances on the surface of fabrics, making them easier to remove during the washing process. Fifthly, during the rinse cycle of the washing machine 100, the air bubbles can help to remove the detergent and dirt particles from the clothes’ fabric thereby ensuring that clothes come out of the wash feeling clean and fresh.

Therefore, the pulsator 102 and the water guide 101 are adapted to generate the air bubbles. The wash tub 103 holds a mixture of the water and the detergent. The pulsator 102 rotates back and forth, creating a washing action that agitates the clothes in the wash tub 103 and helps to remove dirt and stains. As the pulsator 102 rotates, the water is forced up through the water guide 101. The water guide 101 is designed to generate the air bubbles and create turbulence in the water by projections on front panel 201, which helps to lift dirt and debris from the clothes and improves the overall cleaning performance of the washing machine 100. This operation is repeated for a predefined time. The duration of the wash cycle can vary depending on the specific washing machine 100, but typically lasts for several minutes.

As the wash cycle continues, the water guide 101 continues to generate the air bubbles and create turbulence in the wash tub 103, helping to ensure that the clothes are thoroughly cleaned. Once the wash cycle is complete, the washing machine 100 drains the water and spins the clothes to remove excess moisture before the cycle ends.

Referring to Figures 2a to 2d illustrate various aspects of the water guide 101 shown in Figure 1. Specifically, Figure 2a illustrates a front view of the water guide, according to an embodiment of the present disclosure. Further, Figure 2b illustrates a front isometric view of the water guide, according to an embodiment of the present disclosure. Figure 2c illustrates a side view of the water guide, according to an embodiment of the present disclosure. Figure 2d illustrates a top view of the water guide, according to an embodiment of the present disclosure.

The water guide 101 includes a front panel 201 that further includes a leg region 203 extended at the bottom end of the front panel 201. The leg region 203 is adapted to house the inlet 203a (shown in figure 3a) and channels the water from the wash tub 103 inside the water guide 101. Further, the leg region 203 is inclined at an angle with respect to the front panel 201. The shape of the inclined leg region 203 is complementary to an inner curvature of the wash tub 103. Further, a filter (not shown) may also be applied at the inlet 203a to avoid the interference of any lint or impurities from the clothes to interfere with the formation of the air bubbles.

The water guide 101 has an air conduit 204 disposed on the periphery at the top end of the front panel 201. The air conduit 204 helps to introduce air into the water guide 101. The water guide 101 is adapted to mix the water and the air and generate the air bubbles.

The water guide 101 has the outlet 202 which causes the water flowing into the inlet 203a to be discharged back to the water tub 103 due to the rotation of the pulsator 102 into the wash tub 103 in form of the air bubbles. The outlet 202 is provided towards the top end of the front panel 201. The outlet 202 is adapted to dispense the air bubbles through it into the wash tub 103. The outlet 202 is provided at a lower elevation angle than the air conduit 204. Further, based on the level at which the air bubbles should fall into the water tank, the position of the outlet 202 may be fixed accordingly.

Further, the water guide 101 is placed vertically on the inner side walls of the wash tub 103. There may be multiple water guides 101 which are spaced apart circumferentially on the inner side wall of the wash tub 103 so that the air bubbles are generated and are evenly spread over the clothes. Further, to avoid excessive foaming inside the wash tub 103, the detergent quantity has to be provided carefully inside the detergent dispenser tray.

The part of the water in the wash tub 103 (shown in Figure 1) discharged through the water guide 101 back to the wash tub 103 in form of the air bubbles striking at the clothes to fully immerse them into the water of the wash tub 103 by increasing the turbulence in the water of the wash tub 103 by pulsator 102.

As shown in figure 2c, the water guide 101 is attached to the inner side walls of the washing machine 100 through a snap-fitting mechanism. A plurality of interlocks 205 is provided on a periphery of a rear part of the water guide 101. The plurality of interlocks 205 are easy to design and mould, saves on material cost and the water guide 101 turned out to be light-weight. Further, the assembling and disassembling of the water guide 101 with the washing machine 100 is easier.

Details of the rear portion of the water guide 101 are now explained in Figures 3a to 3c. Figure 3a illustrates a rear view of the water guide, according to an embodiment of the present disclosure. Figure 3b illustrates a rear isometric view of the water guide, according to an embodiment of the present disclosure. Figure 3c illustrates a cross-sectional view of the water guide taken along lines A-A’ in Figure 2c, according to an embodiment of the present disclosure.

The water guide 101 includes a front panel 201 having the inlet 203a and the outlet 202. The inlet 203a is disposed proximate to the bottom end of the wash tub 103 and the inlet 203a is adapted to receive the water propelled radially outwardly by the pulsator 102. The outlet 202 is disposed proximate to the top end of the wash tub 103. The water guide 101 further includes a water conduit 300 installed at a rear portion of the front panel 201. The water conduit includes a convergent portion 302, a throat region 301, and the air conduit 204.

The convergent portion 302 includes a first end 302a, a second end 302b, and a body 302c. The first end 302a is adapted to receive the water from the inlet 203a. The second end 302b is adapted to dispense the water to the throat region 301. The body 302c is having a tapered profile between the first end 302a to the second end 302b. The first end 302a is connected to a portion 203b of the leg extension 203 to receive the water from the inlet 203a. The inlet 203a is disposed at the lower end of the leg extension 203.

The throat region 301 is fluidically connected to the second end 302b and the outlet 202. The throat region 301 is adapted to create a negative pressure therein. The throat region 301 is having a first portion 301a, a second portion 301b, and a middle portion 301c. The first portion 301a is fluidically connected to the second end 302b of the convergent portion 302. The second portion 301b is having an opening (not shown). The opening of the second portion 301b is connected to the outlet 202 through a connecting pipe 303 to dispense the air bubbles. The middle portion 301c is fluidically connected to the air conduit 204.

The air conduit 204 includes an inlet port 204a and an outlet port 204b. The air conduit 204 is slightly curved towards the outlet port 204b. The inlet port 204a is disposed at the top end of the front panel 201 and the outlet port 204b is disposed at the middle portion 301c of the throat region 301. The inlet port 204a is disposed at a greater elevation than the outlet 202 of the front panel 201. The air conduit 204 is adapted to introduce air into the throat region 301 upon application of the negative pressure.

The operation of the water guide 101 is explained now. The inlet 203a receives the radially propelled water from the pulsator 102. The water is forced upwards towards the first end 302a of the convergent portion 302. The convergent portion 302 is almost conical in shape which means that the convergent portion 302 is broader at the first end 302a and narrower at the second end 302b.

The throat region 301 has a minimum area. As per Continuity equation of fluid dynamics, when a cross-sectional area decreases then a velocity of a fluid increases. Further, Bernoulli’s principle of fluid dynamics states that when the velocity of the moving fluid increases, the pressure within the fluid decreases. Therefore, the throat region 301 is adapted to create the negative pressure therein.

The water from the convergent portion 302 is then passed to the throat region 301 upon application of the negative pressure through the connecting pipe 303. Simultaneously, the air conduit 204 through the inlet port 204a receives the air. The inlet port 204a is at an atmospheric pressure that is higher than the pressure of the throat region 301. Because of the pressure difference between the inlet port 204a and the throat region 301, the air is sucked inside the throat region 301.

The air is introduced to the throat region 301 through the outlet port 204b. The throat region 301 is adapted to mix the air received from the air conduit 204 and the water received from the second end 302b of the convergent portion 302 for generating the air bubbles. The throat region 301 is further connected to the outlet 202, hence the air bubbles are then dispensed through the outlet 202 into the wash tub 103.

It is more effective to reduce the throat region 301 than to enlarge the inlet port 204a to have a Venturi effect for increasing an amount of the air bubbles. The venturi effect in fluid dynamics results from a reduced cross-sectional area thereby increasing the velocity of the water to rapidly reduce the pressure at the throat region 301, thus causing air dissolved in the water to be extracted in the form of a large volume of the air bubbles.

When the velocity of the water increases, the bubble generation rate also increases but it reaches a state of saturation which depends on the Reynolds number. The Reynolds number further depends on an internal diameter of the throat region 301. The bubble size increases as the internal diameter of the throat region 301 decreases and the Reynolds number increases. This is explained below with the help of equations:

Reynold number = (Inertial forces)/(Viscous forces )

Substituting the formulas, we get

Reynold number = (Fluid velocity (V)*Throat region internal diamter (D)*Fluid density)/(Fluid dynamic viscosity )

Here, the Reynolds number is directly proportional to Fluid velocity (V) and the internal diameter (D) of throat region 301. However, the effect of fluid velocity (V) is more than the internal diameter (D) of throat region 301 as per the continuity equation i.e.,

Area (A1) * Velocity (V1)= Area (A2) * Velocity (V2)
Or
Diameter (d12)* Velocity (V1)= Diameter (d22) * Velocity (V2)

As per the continuity equation, a small change in the diameter changes the velocity by a large amount as the velocity is inversely proportional to the diameter square. This makes the fluid velocity (V) change significantly as compared to the internal diameter (D) of the throat region 301.

Now, considering the Reynold number proportionality to the fluid velocity (V). As the internal diameter of throat region 301 decreases, the area decreases and the velocity increases. The increase in the velocity of the fluid increases the Reynolds's number. Hence, as the internal diameter of the throat region 301 decreases, the area of the throat region 301 decreases. As the area of the throat region 301 decreases, the velocity of the fluid increases. As the velocity of the fluid increases, the bubble size also increases.

Further, due to the tapered profile of the convergent portion 302, the water from the inlet 203a quickly reaches the throat region 301 and generate bubbles as a combined result of the Continuity equation, the Bernoulli’s principle, and the Venturi effect. The quicker the water reaches the throat region 301, the faster will the generation of the air bubbles will occur. The washing machine 100 is then provided with the air bubbles through the outlet 202 to allow effective use of the air bubbles and improve the washing performance of the washing machine 100.

Therefore, the water guide 101 provides a simple and cost-effective way to generate the air bubbles in the washing machine 100. The addition of the air bubbles to the wash cycle can improve the cleaning performance of the washing machine 100. Further, by improving the cleaning performance of the washing machine 100, the water guide 101 aids in the reduction of the amount of time and water needed for the wash cycle. This also aids in making the washing machine 100 energy efficient with lower energy bills and a reduced environmental impact. Further, the water guide 101 is easy to assemble and disassemble and does not require the need of a skilled technician or complex machinery. Furthermore, the water guide 101 is equipped inside the washing machine 100 to provide an improved washing operation.
