[0002] With the advancement of science and technology, people's living standards are getting higher and higher, and daily housework is gradually being replaced by machines instead of manual labor. As common household appliances in daily life, washing machines, shoe washers and other clothing processing equipment have brought great convenience to people's lives.

[0003] During the operation of the clothing processing equipment, if tap water is used as washing water, the temperature is low and cannot reach the optimal dissolution temperature of the laundry detergent or washing powder, resulting in insufficient dissolution of the laundry detergent and laundry liquid, causing waste of the laundry detergent and laundry liquid, and affecting the cleanliness of the laundry; and the incompletely dissolved laundry detergent and laundry liquid condense on the clothes, making it difficult to rinse, resulting in unclean rinsing and affecting the user experience.

[0004] In the prior art, bubble water is used to dissolve laundry liquid or washing powder to accelerate the dissolution rate. However, when the clothing treatment device is used for more than a certain period of time, the bubbler is easily blocked by mud and scale, causing the bubble function to fail.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome at least some of the shortcomings of the prior art and provide a water inlet component of a clothing treatment device, by obliquely inserting the inlet section of a second water inlet branch pipe for providing flushing water to an observation window and / or a sealing window gasket into the inlet section of a first water inlet branch pipe for providing dilution water to a clothing treatment agent, so that when providing dilution water to the clothing treatment agent, a negative pressure can be generated at the inlet of the second water inlet branch pipe, sucking in the gas in the outer drum to produce more bubble water while preventing the water flow from being diverted and causing the clothing treatment agent to not be fully diluted, and after the water inlet is completed, the residual water in the first water inlet branch pipe can be used to flush the observation window and / or the sealing window gasket through the second water inlet branch pipe, thereby preventing residual water in the first water inlet branch pipe and preventing this part of water from absorbing carbon dioxide and producing scale.

[0007] To solve the above technical problems, the first aspect of the present invention is to provide a water inlet assembly for a laundry treatment device, comprising a water inlet main pipe and a first water inlet branch pipe and a second water inlet branch pipe connected to a water outlet of the water inlet main pipe, wherein the first water inlet branch pipe is configured to provide dilution water for a laundry treatment agent, and the second water inlet branch pipe is configured to provide rinsing water to an observation window and / or a sealing window gasket;

[0020] The water storage tank is connected to the inlet section of the first water inlet branch pipe, and a bend pipe communicating with the water storage tank is provided in the inlet section of the first water inlet branch pipe, with the opening of the bend pipe facing the water inlet main pipe.

[0021] In some embodiments, the water storage tank is made of elastic material.

[0043] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but rather to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0045] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0046] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0047] Before introducing the clothes processing device provided by the present invention, the principle that scale deposition is easily generated in clothes processing devices in the prior art will be explained.

[0048] Washing water for laundry machines typically comes from tap water. Since tap water generally contains dissolved calcium and magnesium ions, the harder the water, the higher the calcium and magnesium ion content. Therefore, when water is no longer flowing into the laundry machine, the valve upstream of the inlet pipe closes, and the residual water in the pipe immediately stops flowing. When hard tap water remains open and static in the inlet pipe for a long time, it absorbs gases like carbon dioxide and sulfur dioxide from the air. These carbon dioxide and sulfur dioxide dissolve in water, producing carbonate and sulfate ions. These react with calcium and magnesium ions to form water-insoluble precipitates such as calcium carbonate, magnesium carbonate, and calcium sulfate. These precipitates accumulate and form scale.

[0049] Therefore, to prevent scale buildup, one approach is to reduce the amount of calcium and magnesium ions in the water, for example by using water softening. Another approach is to reduce the amount of carbon dioxide and sulfur dioxide that cause calcium and magnesium ions to precipitate, which is more difficult. Another approach is to reduce the time it takes for hard water to combine with carbon dioxide and sulfur dioxide, allowing the water to dry before they can react. Even if white powder precipitates, it is readily soluble in water, calcium chloride and magnesium chloride, and will be quickly washed away during the next flush.

[0050] Furthermore, when a bubbler is installed at the outlet of the water inlet pipe, due to the thinness of the pipe, the water will remain in the pipe for a long time due to the influence of surface tension between the filter and the water and atmospheric pressure. The bubbler outlet is located closest to the air and is most likely to absorb acidic gases, which is where scale is most likely to accumulate. Over time, this can cause the filter to become clogged, preventing the water from being sprayed out.

[0051] Figure 1A and Figure 1B Schematic diagrams of the structure of a clothes processing device 10 provided according to an exemplary embodiment of the present invention are shown respectively. The clothes processing device 10 is a washing machine, a washer-dryer, a shoe washer, etc., and the present invention does not limit this.

[0052] like Figure 1A and Figure 1B As shown, the laundry treatment device 10 includes a housing 100 and an outer tub 200 and an inner tub disposed within the housing 100. The front side of the housing 100 is provided with a laundry inlet and a door for opening and closing the laundry inlet. The door is provided with an observation window 400, and a sealing window gasket 800 is provided between the laundry inlet and the outer tub 200. The top of the outer tub 200 is connected to a dispenser box 500 via a pipeline for dispensing laundry treatment agent and wash water into the outer tub 200. The inner tub is connected to a drive unit 300 for rotating the inner tub. A drain assembly 700 is also connected to the bottom of the outer tub 200 for draining water from the outer tub 200. As an example, the drain assembly 700 includes a drain pump 720, a water diversion pipe 710, and a drain pipe 730. The water diversion pipe 710 is connected between the outer tub 200 and the inlet of the drain pump 720, and the drain pipe 730 is connected to the outlet of the drain pump 720.

[0053] The clothing treatment device 10 also includes a water inlet assembly 600, which includes a water inlet main pipe 620 and a first water inlet branch pipe 630 and a second water inlet branch pipe 650 connected to the water outlet of the water inlet main pipe 620. A water inlet valve 610 is provided on the water inlet main pipe 620. The first water inlet branch pipe 630 is configured to be connected to the dispenser box 500 for providing dilution water to the clothing treatment agent. The second water inlet branch pipe 650 is configured to provide flushing water to the observation window 400 and / or the sealing window gasket 800; the inlet section of the second water inlet branch pipe 650 is arranged at an angle and inserted parallel to the inlet section of the first water inlet branch pipe 630.

[0054] In addition, a flushing head 660 is further provided at the water outlet of the second water inlet branch pipe 650 . The flushing head 660 may adopt a structure commonly used in the art, and the present invention does not impose any limitation thereto.

[0055] In the above scheme, the inlet section of the second water inlet branch pipe 650 for providing flushing water to the observation window 400 and / or the sealing window gasket 800 is tilted and inserted into the inlet section of the first water inlet branch pipe 630 for providing dilution water to the clothing treatment agent, so that when providing dilution water to the clothing treatment agent, a negative pressure can be generated at the inlet of the second water inlet branch pipe 650 to prevent water flow diversion and the clothing treatment agent from being insufficiently diluted. Moreover, the second water inlet branch pipe 650 can introduce gas into the first water inlet branch pipe 630 at this time to increase the gas content of the water flow in the first water inlet branch pipe 630, and after the water inlet valve 610 is closed, the residual water in the first water inlet branch pipe 630 can be flushed through the second water inlet branch pipe 650 to flush the observation window 400 and / or the sealing window gasket 800, thereby preventing residual water in the first water inlet branch pipe 630 and avoiding scale deposition that affects the bubbler effect.

[0056] In some embodiments, as Figure 2 As shown, the axis of the water inlet main pipe 620 is arranged obliquely downward along the direction of water flow, and the axis of the first water inlet branch pipe 630 is arranged obliquely upward along the direction of water flow. The diameter of the first water inlet branch pipe 630 matches the diameter of the water inlet main pipe 620. The inlet section of the second water inlet branch pipe 650 is arranged obliquely from the intersection of the water inlet main pipe 620 and the first water inlet branch pipe 630 and is inserted parallel to the inlet section of the first water inlet branch pipe 630. It is understandable that the diameters of the first water inlet branch pipe 630 and the water inlet main pipe 620 are larger, while the diameter of the second water inlet branch pipe 650 is smaller.

[0057] In the above scheme, the second water inlet branch pipe 650 is inserted at the lowest point where the water inlet main pipe 620 is connected to the first water inlet branch pipe 630 and is extended along the water flow direction in the first water inlet branch pipe 630. The pipe mouth of the second water inlet branch pipe 650 is facing away from the water flow direction of the water inlet main pipe 620. When water enters the water inlet main pipe 620, negative pressure will be generated at the inner pipe mouth 651 of the second water inlet branch pipe 650, and water will not enter the second water inlet branch pipe 650. When the water inlet valve 610 is closed, the water in the pipe stops flowing. Since the first and second water inlet branches 630 and 650 have openings at both ends, one higher and one lower, water, under the influence of atmospheric pressure and gravity, without the negative pressure, will quickly flow from the first water inlet branch 630 to the second water inlet branch 650, flushing the observation window 400 and the sealing window gasket 800. This allows the first and second water inlet branches 630 and 650 to quickly drain any remaining water after use, preventing the formation of scale. During drainage, as dozens of liters of water are discharged, an equal amount of air enters the outer cylinder 200 through the first and second water inlet branches 630 and 650. This air flow further dries the pipes, further preventing the formation of scale.

[0058] In some embodiments, the inlet section of the second water inlet branch pipe 650 and the inlet section of the first water inlet branch pipe 630 are connected to the outlet section of the water inlet main pipe 620 to form a three-way connector. The three-way connector is detachably connected to the main section of the second water inlet branch pipe 650, the main section of the first water inlet branch pipe 630, and the main section of the water inlet main pipe 620. This allows the three-way connector to be modularized and used as a single, highly reliable, integrated component. During installation, the three-way connector is connected to the main section of the second water inlet branch pipe 650, the main section of the first water inlet branch pipe 630, and the main section of the water inlet main pipe 620.

[0059] In the above scheme, the inlet section of the second water inlet branch pipe 650 and the inlet section of the first water inlet branch pipe 630 are connected to the outlet section of the water inlet main pipe 620 to form a three-way connecting joint, which facilitates the detachable connection of the main section of the second water inlet branch pipe 650, the main section of the first water inlet branch pipe 630 and the main section of the water inlet main pipe 620, enables batch manufacturing and assembly, improves production efficiency, and is also convenient for later maintenance and repair.

[0060] In some embodiments, the outlet of the main section of the first water inlet branch pipe 630 is connected to a bubbler 640, which includes a jet pipe 641 and a bubbler pipe 643. Jet pipe 641 is connected to the three-way connector. Its diameter matches that of the first water inlet branch pipe 630. It is equipped with a jet nozzle 642 that gradually narrows along the water outlet direction. This nozzle 642 is used to increase the solubility of gas in water and the water flow rate. Bubble pipe 643 is connected to jet pipe 641 and is equipped with a filter 646. This filter 646 is used to separate dissolved gas in the water to form microbubble water.

[0061] It should be noted that the axial direction of the bubbler 640 is tilted downward, so a connecting elbow is provided between the outlet of the main pipe section of the first water inlet branch pipe 630 and the bubbler 640 .

[0062] Figure 4 FIG. 6 shows the internal structure of the jet tube 641 and the bubble tube 643 according to an exemplary embodiment of the present invention. Figure 4As shown, as water flows through jet nozzle 642 in jet tube 641, it compresses the water and increases its pressure. This pressure also further increases the gas solubility in the water, pressurizing the air and undissolved bubbles entering through second water inlet branch 650, along with the water itself, thus increasing the amount of air dissolved in the water. After jet tube 641 compresses the water, the outflow velocity increases. After passing through filter screen 646 in bubbler tube 643, the water is blocked at multiple points. The pressure drops dramatically after the blockage points, allowing the dissolved gases in the water to be released as bubbles, thus forming microbubble water.

[0063] In detail, after the water flows through the obstacle, the pressure behind the obstacle decreases, and the gas dissolved in the water will quickly overflow. Due to the surface tension of the water molecules, the water molecules surround the gas, forming bubbles. In other words, the lower the pressure behind the obstacle is compared to the pressure before the obstacle, the more bubbles will overflow. In addition, the more gas dissolved in water, the more precipitation will occur, and the higher the pressure, the easier it is for the gas to dissolve in water. Therefore, the present invention uses the second water inlet branch pipe 650 to introduce gas into the first water inlet branch pipe 630, and allows the gas to naturally dissolve in water in the longer pipeline, and then pressurizes it through the jet tube 641 to allow more gas to dissolve in water. The pressurized water flow rate becomes faster, and after encountering the filter screen 646 in the bubble tube 643, the pressure difference on both sides of the filter screen 646 in the flow direction of the water flow is larger, making it easier for gas to overflow and generate bubbles.

[0064] When the water inlet main pipe 620 stops accepting water, the outlet of the second water inlet branch pipe 650 is open to the atmosphere. Therefore, under the influence of atmospheric pressure, the water in the first water inlet branch pipe 630 and the water inlet main pipe 620 will quickly flow out and will not accumulate, thus preventing scale deposits and affecting the subsequent production of microbubble water. Otherwise, when the water inlet valve 610 is closed and water inlet stops, the rear end of the water inlet main pipe 620 is closed, and the water in the water inlet main pipe 620 will generate negative pressure at the rear when it flows forward, thereby restraining the forward-flowing water flow. Due to the surface tension of water molecules and the small diameter of the water inlet pipe, it is difficult for air to enter through the bubble pipe 643 at the end of the first water inlet branch pipe 630 and relieve the negative pressure. Therefore, the accumulated water cannot be discharged. Due to the small mesh size of the filter 646 in the bubble pipe 643, the surface tension of water molecules is stronger, making it more difficult for air to enter.

[0065] In the present invention, a second water inlet branch pipe 650 is inserted into the first water inlet branch pipe 630. When the valve is closed, the water that is still in the water inlet main pipe 620 and the first water inlet branch pipe 630 and has not flowed out enters the second water inlet branch pipe 650 under the action of air pressure. Moreover, after the water inlet is completed, there will be slight vibration during the operation of the clothing processing device 10. The first water inlet branch pipe 630 and the second water inlet branch pipe 650 are connected to form a transparent structure, and the water film remaining on the filter screen 646 will also accelerate evaporation, thereby preventing scale deposition.

[0066] In some embodiments, as Figure 4 As shown, the jet nozzle 642 can be manufactured integrally with the jet tube 641. The jet nozzle 642 is a nozzle with a smooth transition and gradually narrowing, which can pressurize and speed up the water flowing through it. The pressurization process can increase the solubility of gas in water. The higher the solubility of air in water, the easier it is to generate bubbles and produce more bubbly water. After the water flow is accelerated, the pressure drops sharply after encountering a mesh obstruction structure such as a filter 646, which can precipitate more air and produce more bubbles. Both ends of the jet tube 641 are provided with a second threaded section 6411 or other connection limiting structure, such as a rib or groove, which is detachably connected to the outlet of the first water inlet branch pipe 630.

[0067] In some embodiments, the filter 646 is tilted within the bubble tube 643. For example, the angle α between the filter 646 and the water flow direction of the bubble tube 643 ranges from 5° to 60°. Preferably, α ranges from 10° to 40°. Because the filter 646 is tilted, the area of the liquid sprayed onto the filter 646 is increased, thereby generating more bubbles.

[0068] In some embodiments, the inner wall of the bubble tube 643 is circumferentially provided with a step groove 644 that is elliptical when viewed from its vertical direction, and the filter screen 646 is obliquely clamped on the step groove 644; the jet tube 641 is inserted into the bubble tube 643, and a limit member 647 is embedded between the end of the jet tube 641 and the filter screen 646.

[0069] Specifically, the bubble tube 643 is a straight tube with an inclined stepped groove 644 on its inner wall for retaining the elliptical filter 646. A retaining member 647 is also located within the stepped groove 644 to secure the filter 646. For example, the retaining member 647 is a tube having a standard hollow cylinder at the top and an inclined surface cut off at the bottom to create an elliptical cross-section.

[0070] The inner diameter of the limiter 647 matches the maximum inner diameter of the jet tube 641 and the minimum inner diameter of the bubble tube 643, so that there will be no additional obstruction to the water flow. At the same time, a first threaded section 645 or other pipeline connection structure, such as a rib, a groove, a buckle and other structures, is provided on the top of the bubble tube 643 for detachable connection with the jet tube 641. The bubble tube 643 should match the connection structure of the jet tube 641. After the jet tube 641 and the bubble tube 643 are installed, the jet tube 641 presses tightly against the limiter 647, indirectly fixing the filter screen 646; the filter screen 646 is installed at a larger angle to prevent mud and sand particles from clogging and adhering to the filter screen 646, and can guide mud and sand particles to move to the lower angle.

[0071] Optionally, the filter screen 646 is provided with a sand discharge hole 6461 at a downstream position along the water flow direction, which can discharge the sediment collected there after being filtered by the filter screen 646. In addition, the filter screen 646 is tilted to increase the water flow area and generate more bubbles.

[0072] In addition, the present invention stipulates that the jet tube 641 is detachably connected to the first water inlet branch 630, and the bubble tube 643 is detachably connected to the jet tube 641. Therefore, even if larger particles of mud and sand accumulate on the jet nozzle 642 or the filter screen 646, it is convenient to disassemble the various components of the water inlet assembly 600 for cleaning or replacement.

[0073] In some embodiments, the water inlet assembly 600 further includes a water storage tank 670 connected to the inlet section of the first water inlet branch pipe 630. A curved pipe 680 is disposed within the inlet section of the first water inlet branch pipe 630, communicating with the water storage tank 670. The opening 681 of the curved pipe 680 faces the water flow within the water inlet main pipe 620. Preferably, the opening 681 of the curved pipe 680 is located within the first water inlet branch pipe 630, downstream of the inlet of the second water inlet branch pipe 650. The water storage tank 670 is made of an elastic material.

[0074] Specifically, if Figure 3 As shown, the installation point of the elastic water storage tank 670 is located above the connection between the first water inlet branch 630 and the second water inlet branch 650. The elastic water storage tank 670 is inserted into the first water inlet branch 630 through the connecting pipe 690 and the elbow 680 and is sealed therewith. And the opening 681 of the elbow 680 in the first water inlet branch 630 is opposite to the inner pipe opening 651 of the second water inlet branch 650 in the first water inlet branch 630. When the water inlet valve 610 is opened, the opening 681 of the elbow 680 faces the water flow head-on, and the bubbler 640 has a certain resistance to water. Water will enter the elastic water storage tank 670 through the elbow 680 and the connecting pipe 690 until the water pressure is balanced with the elastic force of the elastic water storage tank 670, refer to Figure 1AWhen the water inlet valve 610 is closed, the elastic force is released, and the water flows out of the elastic water storage chamber 670 and quickly enters the second water inlet branch 650. Figure 1B shown.

[0075] The above solution can increase the water flow rate of the second water inlet branch 650 and accelerate the water backflow at the bubbler 640. After the water backflows, the gas continues to flow inward through the bubbler 640, evaporating the water film on the filter 646 of the bubbler 640, thereby preventing scale deposition.

[0076] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
