[0001] The present invention relates to the technical field of washing equipment, in particular to a clothing processing equipment. Background Art

[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 existing technology and provide a clothing processing device. By connecting a ventilation branch pipe connected to the air vent of the outer drum to the water inlet main pipe, on the one hand, when water is intaken, gas is injected into the water inlet main pipe by using the ventilation branch pipe to increase the amount of air in the water. On the other hand, after the water intake is completed, the gas can form a two-way flow between the water inlet main pipe and the ventilation branch pipe, drying the water film formed at the outlet of the water inlet main pipe, thereby avoiding the formation of scale deposition at the outlet of the water inlet main pipe.

[0007] In order to solve the above technical problems, the present invention provides a clothing processing device, including a casing and an outer drum arranged in the casing, a dispenser box and a water inlet assembly, the water inlet assembly including a water inlet main pipe and a ventilation branch pipe, the water inlet main pipe is configured to provide dilution water to the dispenser box, one end of the ventilation branch pipe is connected to the water inlet main pipe, and the other end is connected to the ventilation hole set on the outer drum.

[0012] In some embodiments, the end of the water inlet main is further connected to a bubbler, wherein the bubbler comprises:

[0013] A jet pipe is connected to the water outlet of the water inlet main pipe. The diameter of the jet pipe matches the diameter of the water inlet main pipe. A jet nozzle is provided in the jet pipe and gradually narrows along the water outlet direction. The jet nozzle is used to increase the solubility of the gas in the water and the water flow rate.

[0014] The bubble tube is connected to the jet tube. A filter is provided in the bubble tube. The filter is used to separate the gas dissolved in the water to form micro-bubble water.

On the other hand, after the water inlet is completed, the gas can form a two-way flow between the water inlet main pipe and the ventilation branch pipe. In particular, when draining water, in order to maintain the air pressure balance in the outer drum, an equal amount of gas will enter the outer drum through the water inlet main pipe as much water is discharged.

[0042] 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

[0043] 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.

[0044] 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.

[0045] 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.

[0046] Before introducing the clothes treating apparatus provided by the present invention, the principle that scale deposition is easily generated in the water inlet assembly of the clothes treating apparatus is first explained.

[0047] 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.

[0048] 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.

[0049] Furthermore, when a bubbler is installed at the outlet of the water inlet pipe, this water will remain in the pipe for a long time due to the thinness of the pipe, the surface tension between the filter and the water, and the influence of atmospheric pressure. The bubbler outlet is located closest to the air, and due to surface tension, a water film easily forms on the filter, which is most likely to absorb acidic gases and deposit scale. Over time, this can cause the filter to become clogged, preventing the release of bubbling water.

[0050] Figure 1 FIG2 shows a schematic structural diagram of a clothes processing device 10 provided according to an exemplary embodiment of the present invention. The clothes processing device 10 is a washing machine, a washer-dryer, a shoe washer, etc., and the present invention is not limited thereto.

[0051] like Figure 1 As shown, the laundry processing device 10 includes a housing 100, an outer drum 200, an inner drum, and a dispenser box 300 disposed within the housing 100. The front side of the housing 100 is provided with a laundry inlet and a door 400 for opening and closing the laundry inlet. The door 400 is provided with an observation window, and a sealing window gasket is provided between the laundry inlet and the outer drum 200. The inner drum is connected to a drive unit for driving the inner drum to rotate.

[0052] The top of the outer tub 200 is connected to the dispenser box 300 via a curved water seal tube 310, which is used to dispense laundry treatment agent and washing water into the outer tub 200. It will be understood that after the laundry treatment agent and washing water are dispensed into the outer tub 200, the space in the outer tub 200 and the space in the dispenser box 300 are separated by the water remaining in the curved water seal tube 310.

[0053] The housing 100 is also provided with a drainage assembly 500 connected to the outer cylinder 200 for draining water from the outer cylinder 200. The drainage assembly 500 adopts an upper drainage structure. It is understood that after the drainage process is completed, the water remaining in the drainage assembly 500 with the upper drainage structure can isolate the outer cylinder 200 space from the outside space. As an example, the drainage assembly 500 includes a drainage pump 510, a water diversion pipe 520, and a drainage pipe 530. The water diversion pipe 520 is connected between the outer cylinder 200 and the inlet of the drainage pump 510, and the drainage pipe 530 is connected to the outlet of the drainage pump 510.

[0054] The clothing processing device 10 also includes a water inlet assembly 600, which includes a water inlet main pipe 610 and a ventilation branch pipe 620. The water inlet main pipe 610 is configured to provide dilution water to the dispenser box 300, and one end of the ventilation branch pipe 620 is connected to the water inlet main pipe 610, and the other end is connected to the ventilation hole 210 provided on the outer drum 200.

[0055] In the above embodiment, when a user uses the laundry treatment device 10 to treat clothes, and after closing the door 400 of the laundry treatment device 10 and starting to let water in, the space within the outer drum 200 is effectively a closed cavity except for the vent 210, due to the provision of the sealing window gasket, the curved water seal tube 310, and the drainage assembly 500 of the upper drainage structure. Therefore, when water is introduced into the outer drum 200, the gas space within the outer drum 200 is compressed, and the gas within the outer drum 200 enters the water inlet main 610 through the vent 210 and the ventilation branch tube 620, injecting gas into the water flow and increasing the amount of air in the water. After water intake is complete and washing begins, the clothes are thrown up and down in the inner drum, causing air disturbance in the outer drum 200. Air also continuously flows through the air holes 210 and the air branch pipe 620 between the outer drum 200 and the water inlet main pipe 610, thereby allowing air to flow in both directions between the water inlet main pipe 610 and the air branch pipe 620, drying the water film formed at the outlet of the water inlet main pipe 610 and preventing scale deposits at the outlet of the water inlet main pipe 610. After washing is complete and drainage begins, the drain pump 510 continuously drains water from the outer drum 200 through the drain pipe 530 and out of the clothing treatment apparatus 10. As the water content in the outer drum 200 decreases, an equal amount of air is discharged through the air branch pipe 620 to balance the air pressure. This air also dries the water film formed at the outlet of the water inlet main pipe 610, further preventing the residual water at the outlet of the water inlet main pipe 610 from absorbing carbon dioxide over a long period of time, forming precipitation and causing scale accumulation.

[0056] In addition, the water inlet main pipe 610 is connected to the outer cylinder 200 through the vent branch pipe 620. When water backflow occurs in the water inlet main pipe 610, the water flow can be diverted to the outer cylinder 200 to prevent water overflow.

[0057] Figure 2 The structure of a water inlet assembly 600 provided according to an exemplary embodiment of the present invention is shown; Figure 3 A schematic diagram of the internal structure of the ventilation branch pipe 620 and the joint pipe 612 provided according to an exemplary embodiment of the present invention is shown; Figure 4 Shown Figure 3 The water inlet assembly 600 can be used for water inlet of multiple steps such as main washing and rinsing of the clothes processing device 10, and the present invention does not limit this.

[0058] like Figures 2 to 4As shown, a mounting hole is opened on the pipe wall of the water inlet main pipe 610, and the ventilation branch pipe 620 is fixedly connected to the water inlet main pipe 610 through the mounting hole. The first end of the ventilation branch pipe 620 is located inside the water inlet main pipe 610, and the air outlet direction of the first end of the ventilation branch pipe 620 is consistent with the water inlet direction of the water inlet main pipe 610. The second end of the ventilation branch pipe 620 is connected to the ventilation hole 210.

[0059] In some embodiments, as Figure 2 As shown, the end of the water inlet main pipe 610 is further connected to a bubbler 630, wherein the bubbler 630 includes a jet pipe 631 and a bubble pipe 632. The jet pipe 631 is connected to the water outlet of the water inlet main pipe 610, and the diameter of the jet pipe 631 matches the diameter of the water inlet main pipe 610. The jet pipe 631 is provided with a jet nozzle 6312 that gradually narrows along the water outlet direction. Figure 5 As shown, the jet nozzle 6312 is used to increase the solubility of gas in water and the water flow rate. The bubble tube 632 is connected to the jet tube 631. The bubble tube 632 is provided with a filter 6324, which is used to precipitate the dissolved gas in the water to form microbubble water.

[0060] Through the above solution, when the valve 700 on the water inlet pipe 610 is opened, water flows from the water inlet pipe 610 to the Figure 1 As the water flows from the right side to the left and enters outer tube 200, the gas space within outer tube 200 is compressed, drawing the gas from outer tube 200 into the water inlet main 610 through the air inlet of vent branch 620. As the water flows, air is entrained and mixed with the water, generating bubbles within the water flow and increasing the air solubility in the water. This also accelerates the water flow. This is because the kinetic energy per unit length of water flow is fixed during flow. When bubbles are mixed into the water, the density of this portion of the water flow decreases, resulting in a faster flow rate and an increased spray distance.

[0061] like Figure 5 As shown, as water flows through the jet nozzle 6312 in the jet tube 631, it compresses the water and increases its pressure. This pressure also further increases the gas solubility in the water. This pressurizes the air entering through the vent branch 620 and the bubbles that remain undissolved in the water, further increasing the amount of air dissolved in the water. After the water is compressed by the jet tube 631, its outflow velocity increases. After passing through the filter 6324 in the bubbler tube 632, 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.

[0062] 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 also occur, and the higher the pressure, the easier it is for the gas to dissolve in water. Therefore, the present invention uses the air branch pipe 620 to introduce gas into the water inlet main pipe 610, and allows the gas to naturally dissolve in water in the longer pipe, and then pressurizes it through the jet pipe 631 to allow more gas to dissolve in water. The pressurized water flow rate becomes faster, and after encountering the filter 6324 in the bubble tube 632, the pressure difference on both sides of the filter 6324 in the direction of water flow is larger, making it easier for gas to overflow and form bubbles.

[0063] However, since the mesh of the filter 6324 in the bubble tube 632 is smaller and the surface tension of water molecules is stronger, a water film is more likely to form on the filter 6324 after the water supply stops. Therefore, the above-mentioned solution of the present invention connects the water inlet main pipe 610 with the air hole 210 of the outer cylinder 200 through the air branch pipe 620, which can also dry the water film formed on the filter 6324, preventing the water film from absorbing gases such as carbon dioxide and sulfur dioxide in the air to form scale and render the filter 6324 ineffective.

[0064] The present invention provides a ventilation branch pipe 620 in the water inlet main pipe 610, and the air outlet of the ventilation branch pipe 620 is located inside the water inlet main pipe 610. The air outlet direction of the air outlet is consistent with the water inlet direction of the water inlet main pipe 610. When the valve 700 is closed, the water in the water inlet main pipe 610 that has not flowed out continues to flow forward under the action of inertia. At this time, the gas will enter the water inlet main pipe 610 through the ventilation branch pipe 620. Since there is no negative pressure restraint, the water in the pipeline will continue to flow unimpeded downstream under the action of inertia and / or gravity until it flows out of the filter 6324.

[0065] As an example, Figure 3 As shown, for ease of manufacturing and installation, the ventilation branch pipe 620 is in an inverted L-shape, with its outlet section (the horizontal section in the figure) located at the axis of the water inlet main pipe 610. The air inlet section (the vertical section in the figure) passes through a mounting hole provided in the wall of the water inlet main pipe 610 and is connected to the ventilation pipe on the outer cylinder 200. Alternatively, the air inlet section may be an inclined section.

[0066] In some embodiments, as Figure 2As shown, the water inlet main pipe 610 includes a main water inlet pipe 611 and a joint pipe 612 detachably connected to the main water inlet pipe 611. The mounting hole is provided on the joint pipe 612. This allows the joint pipe 612 and the vent branch pipe 620 to be modularized and used as a single, highly reliable component. During use, the vent branch pipe 620 can be connected to the joint pipe 612 and then connected to the main water inlet pipe 611.

[0067] Furthermore, if the integral component is required in a pipeline, such as when the main water inlet pipe 611 is directly connected to a faucet valve 700 in a user's home, the main water inlet pipe 611 can be cut and the integral component inserted into the cut ends. For example, annular ribs 6121 can be provided on the outer walls of each end of the joint pipe 612. The ends of the joint pipe 612 can then be inserted into the main water inlet pipe 611 so that the end of the main water inlet pipe 611 extends beyond the annular ribs 6121. The joint pipe 612 can then be secured with a pipe clamp to prevent it from loosening.

[0068] In some embodiments, as Figure 3 and Figure 4 As shown, the connector pipe 612 has a boss 6122 formed on its wall, and the mounting hole is a stepped hole 6123 that passes through the boss 6122. The ventilation branch pipe 620 is securely connected to the boss 6122, with a sealing gasket 622 disposed between the ventilation branch pipe 620 and the stepped hole 6123. This facilitates mass production and assembly of the integral component consisting of the connector pipe 612 and ventilation branch pipe 620.

[0069] As an example, Figure 3 and Figure 4 As shown, a truncated cone boss 6122 is provided at the bottom of the connector pipe 612. A stepped hole 6123 is provided on the boss 6122, extending vertically through the boss 6122. A sealing gasket 622 is provided in the stepped hole 6123 to prevent liquid leakage at the interface. The inner diameter of the stepped hole 6123 increases radially from the inside outward. In addition to accommodating the sealing gasket 622, the stepped hole 6123 also facilitates insertion of the curved ventilation branch pipe 620 into the connector pipe 612. It should be noted that when the air inlet section of the ventilation branch pipe 620 is inclined, the stepped hole 6123 can also be adapted to be an inclined stepped hole 6123 extending obliquely through the boss 6122. Alternatively, the stepped hole 6123 can remain vertical but with a larger diameter, with the sealing gasket 622 still installed vertically, with the vertical portion of the ventilation branch pipe 620 now obliquely extending through the sealing gasket 622.

[0070] In some embodiments, to position the ventilation branch pipe 620 for installation, a flange ring 621 can be provided on the air inlet section of the ventilation branch pipe 620. The height of the flange ring 621 should ensure that the height of the air outlet section of the ventilation branch pipe 620 is aligned with the axis of the joint pipe 612. To ensure that the air outlet section of the ventilation branch pipe 620 is coaxial with the joint pipe 612, multiple through holes are provided on the flange ring 621, and corresponding blind holes are provided on the boss 6122. After assembly and alignment, the flange ring 621 can be fastened with screws 623 to ensure that the two cannot loosen. This also ensures that the two are always coaxially arranged. Since liquids have viscous resistance, the closer to the pipe wall, the greater the resistance, the slower the water flow. Conversely, the closer to the center of the pipe, the faster the water flow, thus maintaining air conduction efficiency.

[0071] In some embodiments, as Figure 5 As shown, the jet nozzle 6312 can be manufactured integrally with the jet tube 631. The jet nozzle 6312 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 more bubbles can be generated. After the accelerated water flow encounters a mesh obstruction structure such as the filter 6324, the pressure drops sharply, which can precipitate more air and generate more bubbles. Both ends of the jet tube 631 are provided with a second threaded section 6311 or other connection limiting structure, such as a rib or groove, which is detachably connected to the outlet of the main water inlet pipe 611.

[0072] In some embodiments, the filter 6324 is tilted within the bubble tube 632. For example, the angle α between the filter 6324 and the water flow direction of the bubble tube 632 ranges from 5° to 60°. Preferably, α ranges from 10° to 40°. Because the filter 6324 is tilted, the area of ​​the liquid sprayed onto the filter 6324 is increased, thereby generating more bubbles.

[0073] In some embodiments, the inner wall of the bubble tube 632 is circumferentially provided with a step groove 6321 that is elliptical when viewed from its vertical direction, and the filter 6324 is obliquely clamped on the step groove 6321; the jet tube 631 is inserted into the bubble tube 632, and a limiter 6326 is embedded between the end of the jet tube 631 and the filter 6324.

[0074] Specifically, the bubble tube 632 is a straight tube with an inclined stepped groove 6321 provided on its inner wall for retaining the elliptical filter 6324. A retaining member 6326 is also provided within the stepped groove 6321 for securing the filter 6324. For example, the retaining member 6326 may be a standard hollow cylinder at the top with the bottom portion cut away to form an elliptical retaining tube.

[0075] The inner diameter of the limiter 6326 matches the maximum inner diameter of the jet tube 631 and the minimum inner diameter of the bubble tube 632, so that there is no additional obstruction to the water flow. At the same time, a first threaded section 6322 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 632 for detachable connection with the jet tube 631. The bubble tube 632 should match the connection structure of the jet tube 631. After the jet tube 631 and the bubble tube 632 are installed, the jet tube 631 presses tightly against the limiter 6326, indirectly fixing the filter screen 6324; the filter screen 6324 is installed at a larger angle, which can prevent the mud and sand particles from clogging and adhering to the filter screen 6324, and can guide the mud and sand particles to move to the lower angle.

[0076] Optionally, the filter screen 6324 is provided with a sand discharge hole 6325 at a downstream position along the water flow direction, which can discharge the sediment collected there after being filtered by the filter screen 6324. In addition, the filter screen 6324 is tilted to increase the water flow area and generate more bubbles.
