Description

Technical Field

[0001] This invention belongs to the technical field of clothing processing equipment, specifically relating to a water inlet system and clothing processing equipment. Background Technology

[0002] With the widespread use of home appliances and people's increasing demands for quality of life, modern garment processing equipment (such as front-loading washing machines) has become an essential appliance for many families. Through automated washing and drying processes, garment processing equipment greatly reduces the burden of housework and improves living efficiency and hygiene. Among them, the water inlet system, as an important component of garment processing equipment, is responsible for applying water to the clothes, ensuring that each garment receives thorough cleaning and care.

[0003] In the prior art, a water seal structure is usually set in the water inlet system of the garment processing equipment, or a check valve or other device is installed in the water inlet pipe to prevent foam and / or water vapor generated during the washing process from overflowing back into the water box in large quantities through the water inlet pipe of the water inlet system.

[0004] However, during the use of the above solution, since the outlet of the water inlet pipe is usually located on the top of the tubular module near the door, when the door of the clothing processing equipment is opened outward with water in the water inlet pipe, a negative pressure state will be formed due to the rapid change of air pressure inside the tubular module. This will affect the stability of the water in the water inlet pipe, leading to the problem of water dripping from the outlet of the water inlet pipe, which seriously affects the user experience.

[0005] Therefore, designing a water inlet system for a garment processing device that can prevent water from dripping from the outlet of the water inlet pipe during the opening of the door has become a technical problem that urgently needs to be solved by those skilled in the art.

[0006] In view of this, the present invention is proposed. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a water inlet system for a garment processing device, which solves the problem of water dripping from the outlet end of the water inlet pipe when the door of the garment processing device is opened.

[0008] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0009] A water inlet system for a garment processing device includes: an inlet pipe having a bent pipe section with one end connected to a water inlet, and an outlet pipe section connected to a cylindrical module of the garment processing device; and a drain pipe disposed on the peripheral wall of the bent pipe section for draining water stored in the bent pipe section.

[0010] Furthermore, the bent pipe section has a first bent section forming a water seal and a second bent section for connecting the first bent section and the outlet pipe section; the bending direction of the second bent section is opposite to that of the first bent section, and the drain pipe is disposed between the bend of the second bent section and the bend of the first bent section.

[0011] Preferably, the distance between the bent portion of the second bending section and the axis of the cylindrical module is less than the distance between the bent portion of the first bending section and the axis of the cylindrical module.

[0012] Furthermore, one end of the drain pipe is located on the peripheral wall downstream of the first bend section and is positioned horizontally close to the second bend section, while the other end is connected to the interior and / or exterior of the garment processing equipment.

[0013] Preferably, the diameter of the drain pipe is smaller than the diameter of the first bend section.

[0014] Furthermore, the first bend section is an upward-opening U-shaped pipe section, located above the cylinder opening on the front side of the cylinder module; one end of the U-shaped pipe section extends from bottom to top to the water inlet, and the other end passes through the second bend section and the water outlet section in sequence to connect with the cylinder module from the top of the cylinder opening; the other end of the drain pipe extends to the cylinder opening and is located below the water outlet section.

[0015] Preferably, the U-shaped pipe section is inclined in the horizontal direction along the outer periphery of the cylinder module towards the cylinder opening.

[0016] Furthermore, the port of the drain pipe and the bend section is facing upwards and located above the lowest formation height of the water seal within the bend section;

[0017] Preferably, the end connecting the drain pipe and the bend in the pipe section extends into the interior of the bend in the pipe section.

[0018] Furthermore, a water box is provided above the cylinder module, and the water inlet is located on the side of the water box; the bent pipe section is set below the water inlet and is located above the cylinder opening; the drain pipe is located on the side of the bent pipe section near the cylinder opening.

[0019] Furthermore, the circumferential wall of the bent pipe section is provided with a vent pipe for connecting to the outside atmosphere;

[0020] Preferably, the vent pipe is located close to the water outlet section and downstream of the end where the drain pipe connects to the bend section;

[0021] Preferably, the end of the vent pipe connected to the bend section is higher than the end of the drain pipe connected to the bend section.

[0022] Furthermore, the connecting ends of the vent pipe and the bent pipe section are set vertically and vertically corresponding to the connecting ends of the drain pipe.

[0023] Another object of the present invention is to provide a garment processing device and a water inlet system for installing the garment processing device.

[0024] Furthermore, a window gasket connected to the cylinder module is provided around the cylinder opening on the front side, and one end of the water outlet pipe section and the drain pipe are inserted into the window gasket.

[0025] Preferably, the outlet pipe and the drain pipe are inserted into the window gasket at the top and bottom of the window gasket, respectively.

[0026] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0027] 1. This invention can effectively drain the water stored in the bend section of the water inlet pipe by setting a drain pipe on the peripheral wall of the bend section, preventing the water stored in the bend section from flowing to the outlet end of the water inlet pipe due to changes in air pressure or opening and closing of the door, and avoiding water dripping from the outlet end of the water inlet pipe.

[0028] 2. The present invention extends the drain pipe into the interior of the first bend section through the connection end of the drain pipe, which better limits the water seal height and ensures that excess water can be discharged in time when needed, without affecting the water seal formed normally in the first bend section and the normal water supply of the water inlet pipe.

[0029] 3. This invention, by setting a vent pipe on the peripheral wall of the bent pipe section that communicates with the outside atmosphere and placing it near the water outlet section and downstream of the connection end between the drain pipe and the bent pipe section, can effectively balance the air pressure inside and outside the pipe, ensuring that the water inlet system can effectively balance the internal air pressure during operation and preventing water seal damage caused by air pressure fluctuations. Combined with the design of the drain pipe, it further prevents water dripping at the water outlet of the water inlet pipe.

[0030] 4. By aligning the connecting ends of the vent pipe and the bent pipe section with the connecting end of the drain pipe, the present invention allows the condensate water condensed in the vent pipe to drip into the drain pipe, thus preventing the water in the inlet pipe from being contaminated and affecting the washing effect of the washing machine.

[0039] To make the objectives, 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 with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

Therefore, they should not be construed as limiting this invention.

[0041] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] like Figures 1 to 3As shown, this embodiment discloses a water inlet system for a clothing processing device. The clothing processing device can be any existing type or model of clothing processing equipment, such as a drum washing machine, a top-loading washing machine, a dryer, a clothing processing cabinet, or a washer-dryer combo. The water inlet system supplies water to the clothing processing device, and in particular, the spray system, as one part of the water inlet system, is used to evenly spray water onto the clothes, thereby increasing the efficiency of washing clothes. The following embodiment uses a drum washing machine as an example, with the water inlet system being the spray system of that drum washing machine.

[0043] like Figure 1 As shown, in this embodiment, the drum washing machine includes a cabinet and a drum module 6 installed inside the cabinet. The cabinet has an inlet for loading clothes, located on the front side of the cabinet. A window gasket 61 is provided between the inlet and the drum opening 60 of the drum module 6. The front side of the cabinet has a door that is adapted to the inlet to open or close the inlet. The door has a glass window that protrudes from the drum opening 60 into the drum module 6, occupying part of the space inside the drum module 6, for observing the washing status of the clothes inside the washing machine.

[0044] In this embodiment, the spray system of the drum washing machine is used to evenly spray water onto the clothes and the spray glass window during the washing process to ensure that the clothes are thoroughly cleaned and cared for. The water inlet pipe of the spray system of the drum washing machine is a spray pipe 1, and one end of the spray pipe 1 is connected to the water inlet 51 through a bent pipe section 10. The water inlet 51 is usually located at the top or front of the washing machine body. The spray pipe 1 is connected to the water source through the water inlet 51 to ensure that the spray system can receive sufficient water when it is started. The bent pipe section 10 is designed as a pipe section with a specific bending angle, usually U-shaped or S-shaped, so as to form a stable water seal within the bent pipe section 10 to prevent water droplets from dripping out from the outlet end. The outlet end of the spray pipe 1 is connected to the drum module 6 of the clothes handling equipment through the outlet pipe section 11. Furthermore, the water outlet pipe section 11 extends into the cylinder module 6, and the water outlet nozzle on the water outlet pipe section 11 evenly distributes the water flow onto the clothes, ensuring that each piece of clothing can fully contact the water flow and achieve the ideal cleaning effect.

[0045] In this embodiment, the drain pipe 2 is installed on the peripheral wall of the bent pipe section 10. Its main function is to drain some of the water stored in the bent pipe section 10 when the spraying is not in operation. This maintains the stability of the water seal within the bent pipe section 10 and prevents water from dripping from the spray nozzles. Specifically, the drain pipe 2, through its placement, controls the height of the water seal that can be formed within the bent pipe section 10, preventing the water seal from being broken by negative pressure caused by the door opening operation. This prevents water from leaking from the spray nozzles on the outlet pipe section 11 of the spray pipe 1, further improving the user experience of the washing machine. The other end of the drain pipe 2 extends to the inside or outside of the washing machine's cabinet, ensuring that excess water can be effectively drained without affecting the normal operation of the equipment.

[0046] In another embodiment, the spray pipe 1 is configured with a bent pipe section 10 to accommodate the surrounding components. Water can be stored at the bend of the bent pipe section 10, but not enough to form a water seal. The drain pipe 2 is located on the peripheral wall of the bent pipe section 10 and downstream of the bend where water can be stored. If there is residual water in the bent pipe section 10, and a negative pressure occurs in the cylinder module 6 due to the operation of moving the door module outward or other circumstances, the drain pipe 2 is designed to drain the residual water in the bent pipe section 10, thus preventing the water nozzle from dripping.

[0047] like Figures 2 to 3 As shown, in this embodiment, the bent pipe section 10 has a first bent section 101 forming a water seal and a second bent section 102 connecting the first bent section 101 and the outlet pipe section 11. Specifically, the bending direction of the second bent section 102 is opposite to that of the first bent section 101, so that when the water flows through the bent pipe section 10, the flow direction of the water can be effectively controlled and a stable water seal can be formed. The drain pipe 2 is disposed between the bend of the second bent section 102 and the bend of the first bent section 101. When the water stored in the bend of the first bent section 101 moves downstream of the bent pipe section 10 due to the negative pressure inside the cylinder module 6, the excess water flows out through the drain pipe 2, preventing water droplets from dripping from the outlet end of the spray pipe 1.

[0048] Specifically, in this embodiment, the bend of the first bending section 101 protrudes downwards, and a stable water seal can be formed at its bottom. When the washing machine stops spraying or the internal air pressure changes, it prevents foam and / or water vapor generated in the drum module 6 during the washing process from overflowing back into the water box 5 through the spray pipe 1, causing foam and / or condensation in the water box 5 and affecting the user experience. The bend of the second bending section 102 protrudes upwards. When the washing machine stops spraying or the internal air pressure changes, combined with the setting of the drain pipe, it can prevent water droplets from leaking out of the water nozzle of the spray pipe 1, keeping the equipment clean. Furthermore, the drain pipe 2 is set between the bend of the second bending section 102 and the bend of the first bending section 101, serving to drain the water. When the water seal moves downstream under the negative pressure generated in the cylinder module 6, the excess water is discharged through the drain pipe 2, thereby maintaining the height of the water seal and preventing water from entering the outlet pipe section 11 and causing the water nozzles of the spray pipe 1 to drip.

[0049] Preferably, in this embodiment, in the horizontal direction, the distance from the bend of the second bending section 102 to the axis of the cylindrical module 6 is less than the distance from the bend of the first bending section 101 to the axis of the cylindrical module 6. This design effectively limits the movement range of the water seal when the sprinkler system stops working, allowing the drain pipe 2 to drain excess water more quickly and maintain the stability of the water seal. Furthermore, the shorter distance design also helps to reduce the water flow path, improving the response speed and overall efficiency of the sprinkler system.

[0050] In the above embodiments, the spray system can adapt to frequent air pressure changes, especially during door opening and closing operations, ensuring the stability of the water seal and the normal operation of the system. The drain pipe 2 effectively prevents water leakage after the water seal is damaged, making the spray system not only reliable but also significantly reducing the need for equipment cleaning due to water leakage, thus improving the user experience.

[0051] In this embodiment, one end of the drain pipe 2 is disposed on the peripheral wall downstream of the first bend section 101 and is disposed horizontally close to the second bend section 102, and the other end is connected to the interior and / or exterior of the clothing processing equipment.

[0052] Specifically, in this embodiment, the drain pipe 2 is arranged horizontally close to the second bend section 102. This design ensures that the drain pipe 2 can effectively control the height of the water seal within the first bend section 101, preventing excessive water accumulation in the system due to water seal movement or air pressure changes, which could easily damage the water seal. When the water seal within the first bend section 101 moves downstream due to negative pressure, excess water is promptly discharged through the drain pipe 2 located on the periphery of the first bend section 101.

[0053] Specifically, in this embodiment, the other end of the drain pipe 2 is connected to the cylinder module 6 of the clothing processing equipment to ensure that the discharged water can be smoothly discharged from the equipment.

[0054] In another specific embodiment, the other end of the drain pipe 2 is connected to the drain outlet outside the clothing processing device to ensure that the discharged water can be smoothly discharged from the device.

[0055] Preferably, in this embodiment, the diameter of the drain pipe 2 is smaller than the diameter of the first bend section 101. Since the first bend section 101 is part of the spray pipe 1, the smaller diameter of the drain pipe 2 ensures that it will not interfere with the normal water supply and spraying operation of the spray pipe 1. In addition, it also ensures that the formation and stability of the water seal within the first bend section 101 are not affected.

[0056] like Figure 3 As shown, in this embodiment, the connecting end of the drain pipe 2 and the first bend section 101 is designed with the port facing upwards, and the port position is set above the lowest formation height of the water seal within the first bend section 101. This design helps ensure that the water seal does not easily flow into the drain pipe 2 during normal formation, thus avoiding affecting the formation of the water seal; at the same time, when the water seal is too high, excess water can be discharged through the drain pipe 2, maintaining the stability of the water seal.

[0057] When the water seal is formed at the bottom of the first bend 101, the water seal will not be easily discharged under normal circumstances because the port of the drain pipe 2 faces upwards, ensuring that the water volume in the spray pipe 1 is sufficient to maintain the normal operation of the spraying operation. Water will only flow into the drain pipe 2 for discharge when the water seal height rises due to internal air pressure changes or other factors, thereby preventing the water seal from being too high and affecting the stability of the system, which would cause the water nozzles to drip easily when the spraying operation is not in progress.

[0058] Preferably, in this embodiment, the connecting end of the drain pipe 2 and the first bend section 101 extends into the interior of the first bend section 101. Specifically, the port of the drain pipe 2 used for water inlet during drainage extends into the first bend section 101. This limits the water seal height while ensuring that excess water can be discharged in a timely manner when needed, without affecting the water seal that is normally formed within the first bend section 101. Simultaneously, it maintains a normal water supply to the spray pipe 1, ensuring that the spray system of the equipment can operate stably at all stages of operation.

[0059] In a further preferred embodiment, the port connecting the drain pipe 2 and the first bend section 101 is horizontally positioned, which helps to further maintain the stability of the water seal. This is because, during water seal formation, the horizontal port is not directly exposed within the water seal; water only enters the drain pipe 2 when the water seal height exceeds the port. This design avoids excessive leakage of the water seal. Simultaneously, the horizontally positioned port also prevents premature leakage of the water seal due to air pressure fluctuations or water flow fluctuations within the spray pipe 1, ensuring the water seal remains stable throughout the entire operation and preventing premature leakage from the drain pipe 2. Thus, the spray system can maintain stable operation under various working conditions, preventing dripping from the spray pipe 1 or poor spraying performance due to water seal disruption.

[0060] like Figures 1 to 3 As shown, in this embodiment, the first bend section 101 is designed as an upward-opening U-shaped pipe section. The U-shaped pipe section is positioned above the cylinder opening 60 on the front side of the cylinder module 6, effectively forming a stable water seal. Furthermore, one end of the U-shaped pipe section extends from bottom to top and connects to the water inlet 51 to ensure that water can smoothly enter the spray system during water intake. The other end passes sequentially through the second bend section 102 and the outlet pipe section 11, and finally connects to the cylinder module 6, realizing water circulation and spraying functions.

[0061] Specifically, in this embodiment, the U-shaped pipe section is located on the upper side of the outer cylinder of the cylinder module 6, with its opening facing upwards. That is, it extends downwards first and then bends upwards to form a U-shape; it bends downwards from the water inlet 51 and extends towards the outer cylinder until it connects with the outer cylinder. This ensures the stability of the water seal and effectively prevents water from dripping from the outlet end of the spray pipe 1.

[0062] In this embodiment, one end of the drain pipe 2 is connected to the peripheral wall of the U-shaped pipe section, and the other end extends to the cylinder opening 60, and is designed to be located below the water outlet pipe section 11. When the water seal changes due to air pressure changes or water level rises, excess water can be discharged in time through the drain pipe 2, preventing overflow problems caused by excessively high water seal. Furthermore, the drain pipe 2 is located below the water outlet pipe section 11, which not only guides excess water flow smoothly into the cylinder, but also effectively prevents dripping when the user opens and closes the door, making the design of the drain pipe 2 more effective.

[0063] In some specific embodiments, the drain pipe 2 on the U-shaped pipe section makes the liquid level in the U-shaped pipe section 3mm lower than the highest point of the U-shaped pipe section.

[0064] Specifically, in this embodiment, one end of the drain pipe 2 is connected to the peripheral wall of the U-shaped pipe section, and the other end extends to the cylinder opening 60 and is located below the water outlet pipe section 11. This way, when the water seal experiences pressure changes or a rise in water level, excess water can be discharged promptly through the drain pipe 2, preventing overflow caused by an excessively high water seal. Simultaneously, the drain pipe 2 guides water flow from the lower part of the cylinder opening 60 near the cylinder module 6 into the interior of the cylinder module 6, preventing the drain pipe 2 from malfunctioning and improving the user experience.

[0065] More specifically, in this embodiment, a window gasket 61 connected to the cylinder module 6 is provided around the cylinder opening 60 on the front side of the cylinder module 6. The window gasket 61 is mainly used to seal the cylinder opening 60 and prevent water leakage. At the same time, one end of the water outlet pipe section 11 and the drain pipe 2 are both inserted into the window gasket 61, making the connection between the spray pipe 1 and the drain pipe 2 and the cylinder module 6 more stable, increasing the sealing performance, and preventing water droplets or water flow from leaking to the outside of the equipment during operation.

[0066] In the above embodiment, the outlet pipe section 11 is used to guide the water flow from the spray pipe 1 into the cylinder module 6, while the drain pipe 2 is used to drain excess water from the spray pipe 1. One end of both is precisely embedded in the window gasket 61 through a structural design, ensuring no water leakage during equipment operation. The insertion of the outlet pipe section 11 and the drain pipe 2 not only enhances the system's sealing performance but also achieves a tight fit with the cylinder module 6 through the window gasket 61, making the water flow into the cylinder module 6 smoother.

[0067] Preferably, in this embodiment, the water outlet pipe section 11 and the drain pipe 2 are respectively inserted at the top and bottom of the window mat 61. The design of inserting the water outlet pipe section 11 at the top of the window mat 61 ensures that water enters the cylinder from a higher position. Utilizing gravity and the angle of the pipe design, the water flow can be more evenly distributed on clothing, enhancing the spraying effect. The drain pipe 2 is inserted at the bottom of the window mat 61, so that when water is discharged, excess water is drained through the lower-positioned drain pipe 2. This ensures that water flowing from the drain pipe 2 will not drip from above the inlet when the user opens and closes the door, improving the user's experience when opening and closing the door. Of course, provided that no dripping occurs when the door is opened, the water outlet of the drain pipe 2 can also be located on the side of the window mat 61 in the middle position.

[0068] In a further preferred embodiment, the bottom of the window pad 61 is provided with a drain outlet facing the inside of the cylindrical module 6, and the water flowing from the spray pipe 1 into the drain pipe 2 flows into the cylindrical module 6 through the drain outlet.

[0069] Preferably, in this embodiment, the U-shaped pipe section is inclined in the horizontal direction along the outer periphery of the cylinder module 6 towards the cylinder opening 60. The inclined U-shaped pipe section can guide the water flow smoothly along the pipe wall of the U-shaped pipe section when the sprinkler system is working, avoiding the setting of the drain pipe 2 from affecting the water flow efficiency during the sprinkler process, thereby improving the efficiency and effect of the sprinkler work.

[0070] Furthermore, the angled U-shaped tube section optimizes the space utilization inside the drum washing machine, allowing for a more compact and rational arrangement of internal components. This not only improves space utilization but also simplifies the internal structure, facilitating maintenance and manufacturing. The overall design helps reduce interference between internal components, ensuring smooth and reliable operation.

[0071] like Figures 1 to 2 As shown, in this embodiment, a water box 5 is provided above the cylindrical module 6. The water box 5 is used to add water or a mixture of water and detergent into the cylindrical module 6. A water inlet 51 is located on the side of the water box 5, through which water can flow into the spray pipe 1 and ultimately into the cylindrical module 6. Further, the water box 5 is located above the side of the cylindrical module 6, and the bent pipe section 10 is positioned below the water inlet 51 and above the cylindrical opening 60; the drain pipe 2 is located on the side of the bent pipe section 10 near the cylindrical opening 60.

[0072] Specifically, in this embodiment, the first bend 101 and the second bend 102 of the U-shaped pipe section are sequentially arranged between the water box 5 and the cylinder opening 60, and are located above the cylinder opening 60. The drain pipe 2 is located downstream of the first bend 101, and its position is lower than the height of the water inlet 51. This allows the water level accumulated in the U-shaped pipe section to be controlled within a reasonable range when needed, ensuring the stability of the water seal height, while not affecting the water pressure and flow of the spray system. This solves the problem of water dripping from the spray nozzles of the spray pipe 1 during the opening process after washing, and also ensures the overall working performance of the spray system.

[0073] In the above embodiments, the spray system effectively prevents water leakage when the spray pipe 1 stops working, ensuring the system remains stable under various operating conditions. Meanwhile, the bend in the pipe section 10 located between the water box 5 and the nozzle 60 makes efficient use of the internal space of the equipment, improving the guidance and efficiency of the water flow, and further enhancing the overall performance and user experience of the spray system.

[0074] In this embodiment, a vent pipe 3 for connecting to the outside atmosphere is provided on the peripheral wall of the bent pipe section 10. The vent pipe 3 is located near the water outlet pipe section 11 to ensure that the sprinkler system can effectively balance the internal air pressure during operation, preventing water seal damage caused by air pressure fluctuations. In conjunction with the design of the drain pipe 2, it further prevents water dripping from the sprinkler head of the sprinkler pipe 1. Furthermore, as the door moves outward, the space occupied by the glass window creates a negative pressure state within the cylindrical module 6. The vent pipe 3 is used to balance the air pressure, so that the water stored in the inlet pipe or the residual water in the water box 5 will not be drawn to the water outlet pipe section 11 due to the negative pressure state within the cylindrical module 6, thereby preventing water dripping from the water outlet nozzle.

[0075] Specifically, in this embodiment, the vent pipe 3 is located downstream of the end where the drain pipe 2 connects to the bend pipe section 10. This arrangement helps to prevent excessive leakage of the water seal within the vent pipe 3 during drainage, ensuring that the vent pipe 3 can function properly for air pressure regulation. Simultaneously, the downstream location of the vent pipe 3 allows for better adaptation to the movement of the water seal, ensuring smooth water flow without affecting the drainage process.

[0076] In some specific embodiments, the vent pipe 3 is disposed on the second bend section 102. The vent pipe 3 extends upward from the peripheral wall above the second bend section 102 and finally extends to the water box 5, communicating with the outside atmosphere through the water box 5, thereby balancing the air pressure inside the washing machine. This arrangement of the vent pipe 3 can effectively prevent the water seal from becoming unstable due to changes in internal air pressure during the operation of the washing machine. At the same time, by communicating with the outside atmosphere, it ensures the balance of air pressure inside and outside the system, avoiding the problem of water dripping from the spray head when there is water in the spray pipe 1 due to pressure imbalance and entering the water outlet pipe section 11.

[0077] Furthermore, in the above specific embodiment, the water box 5 includes a cover and a box body. The cover is used to close the opening of the water box 5 and has a venting channel. The venting channel is arranged on one side of the cover and is responsible for guiding airflow to ensure air pressure balance. The end of the vent pipe 3 that connects to the water box 5 is located on the side of the cover. The vent pipe 3 connects to the venting channel through the side of the cover, and the venting channel can smoothly guide the internal airflow to the outside atmosphere. At the same time, the cross-sectional area of ​​the vent pipe 3 along its radial direction is larger than the cross-sectional area of ​​the venting channel to prevent water from being drawn out due to changes in air pressure.

[0078] Furthermore, the ventilation channel is connected to the interior of the water box 5 through its bottom. Specifically, the bottom wall of the ventilation channel is provided with a ventilation port that communicates with the interior of the water box 5. The ventilation port communicates with the outside atmosphere through the box body of the water box 5.

[0079] Preferably, in this embodiment, the end of the vent pipe 3 connected to the bend section 10 is higher than the end of the drain pipe 2 connected to the bend section 10. This design ensures that when water flows through the bend section 10, it first exits through the drain pipe 2, while the vent pipe 3 is mainly used to balance the air pressure, preventing water from directly entering the vent pipe 3. This height difference design ensures that the vent pipe 3 can maintain its connection with the outside atmosphere while the water seal is stable, without being affected by the water flow, thereby improving the working stability and efficiency of the sprinkler system.

[0080] like Figure 3 As shown, in this embodiment, the connecting ends of the vent pipe 3 and the bent pipe section 10 are vertically aligned with the connecting end of the drain pipe 2. Specifically, some water vapor generated during the operation of the washing machine may enter the vent pipe 3 through the spray pipe 1. This water vapor will condense into water droplets inside the vent pipe 3, affecting the normal operation of the spray system. By vertically aligning the vent pipe 3 and the drain pipe 2, the condensate water condensed inside the vent pipe 3 can drip into the drain pipe 2, thereby preventing the spray water from being contaminated and ensuring that the washing effect of the washing machine is not affected. Preferably, the outlet end of the drain pipe 2 is directly connected to the drain outlet outside the washing machine.

[0081] In this embodiment, not only can the air pressure in the spray system be effectively adjusted to prevent even a single drop of water from the spray pipe, but the smooth operation of the system can also be ensured, avoiding water seal damage caused by air pressure issues, thus guaranteeing the high efficiency and stability of the spray operation.
