[0037] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0039] The embodiment of the present application provides a clothing processing device 100, including a washing tub 1, a water inlet structure, a venturi tube 3 and a piston assembly. The clothing processing device 100 may be a washing machine or a washing-drying machine, etc. The clothing processing device 100 proposed in the embodiment of the present application can solve the technical problem that the existing anti-overflow device is prone to difficulty in controlling the water level due to sensor failure. The following will be described in conjunction with the accompanying drawings.

[0040] In the embodiments of the present application, Figure 1 and Figure 2 As shown, the laundry treatment device 100 includes a washing tub 1, a water inlet structure, a venturi tube 3 and a piston member 4. The upper portion of the washing tub 1 is provided with an overflow port 11; the water inlet structure has a water inlet channel and an air cavity 91, the air cavity 91 has a first opening and a second opening, the first opening is in communication with the overflow port 11, and a cavity wall of the air cavity 91 is partially provided with or constructed as a movable part; one end of the venturi tube 3 is in communication with the water inlet channel, and the other end leads to the washing tub 1, and the narrow portion 31 of the venturi tube 3 is in communication with the second opening; the piston member 4 is provided in the water inlet channel, and the piston member 4 is movably provided to open or close the water inlet channel; the movable part is configured to drive the piston member 4 to move.

[0041] The washing tub 1 is used to hold washing water. An overflow port 11 is provided at the top of the washing tub 1. When the water level in the washing tub 1 is higher than the overflow port 11, the water will flow out from the overflow port 11. The washing tub 1 also has a water inlet, and water transported by the water inlet structure can enter the washing tub 1 through the water inlet.

[0042] The venturi tube 3 is a pipe system for conveying fluids such as liquids and gases. It is a pipe whose diameter first contracts and then gradually expands in the direction of fluid flow. The venturi tube 3 can be made of metal (such as steel, stainless steel) or plastic (such as polyvinyl chloride), and has certain strength and corrosion resistance. Herein, the narrower diameter area in the middle of the venturi tube 3 is named as the narrow part 31. When the fluid flows through the venturi tube 3, the narrow part 31 generates negative pressure, thereby sucking air through the opening at the narrow part 31.

[0043] The water inlet structure has a water inlet channel and an air cavity 91. The water inlet channel is mainly used to connect a water supply device such as a faucet and the washing tub 1. After the water flows out of the water supply device, it passes through the water inlet channel and the venturi tube 3 and finally flows into the washing tub 1. The air cavity 91 is used to accommodate air. The air cavity 91 has a first opening and a second opening. The first opening is connected to the overflow port 11, and the second opening is connected to the narrow portion 31 of the venturi tube 3. The cavity wall of the air cavity 91 is partially configured as a movable movable part. When the air pressure in the air cavity 91 changes, the movable part can move in the direction of the inside and outside of the air cavity 91 under the action of the air pressure, thereby driving the piston part 4. For example, when the air pressure in the air cavity 91 is lower than the external air pressure, the movable part moves in the direction of the inside of the air cavity 91. When the air pressure in the air cavity 91 is higher than or equal to the external air pressure, the movable part can be reset in the direction away from the inside of the air cavity 91 under the reset action of its own deformation or the action of the air pressure. Specifically, the cavity wall of the air cavity 91 can be partially constructed as a deformable structure, so that when the air pressure in the air cavity 91 changes, the deformable structure will deform along the inner and outer directions of the air cavity 91, and accordingly, the deformable structure can constitute a movable part, or a movable part can be installed on the deformable structure; a movable plate that can move toward the inner direction of the air cavity 91 can also be arranged on the cavity wall of the air cavity 91, so that when the air pressure in the air cavity 91 changes, the movable plate moves along the inner and outer directions of the air cavity 91, and accordingly, the movable plate can constitute a movable part, or a movable part can be installed on the movable plate. It can be understood that when the cavity wall is partially set as a movable plate, the movable plate slides and seals with the cavity wall to avoid air leakage from the contact point between the two.

[0044] In the clothes processing device 100 provided by the present application, in the initial state, the water inlet channel is in an open state, at this time, water is transported into the water inlet channel; when water is normally inlet, water can enter the washing tub 1 through the water inlet channel. When the water level does not submerge the overflow port 11, the air cavity 91 communicates with the outside through the overflow port 11, and when the water flows through the venturi tube 3, a negative pressure is generated to absorb the air in the air cavity 91. At the same time, the outside air can be replenished into the air cavity 91 through the overflow port 11, so that the air pressure inside and outside the air cavity 91 can maintain a pressure balance, thereby ensuring smooth water inlet and continuous water inlet; when the water level in the washing tub 1 rises to submerge the overflow port 11, the gas in the air cavity 91 cannot be replenished, so that the internal air pressure becomes smaller and smaller. Under the action of the pressure difference, the cavity wall of the air cavity 91 is pressed inward, so that the movable part moves in the direction of the air cavity 91, and then the piston part 4 is driven to move to block the water inlet channel and stop water inlet. The clothing processing device 100 mainly relies on a simple and non-destructive mechanical structure to achieve the anti-overflow function. The structure is simple, easy to implement, and not prone to failure. The water level can be automatically controlled in a relatively stable manner.

[0045] In some embodiments, the movable member is drivingly connected to the piston member 4, so that when the movable member moves, it drives the piston member 4 to move. The driving connection may refer to a connection relationship in which two parts are connected to each other and there is a contact, or it may refer to a connection relationship in which the driven part is indirectly acted on by a magnetic field force through magnetic drive or the like, and there is no direct contact.

[0046] In some embodiments, the water inlet structure includes a shell and an elastic diaphragm 6, wherein the shell defines the water inlet channel and the accommodating chamber, and the elastic diaphragm 6 is arranged in the accommodating chamber to separate the accommodating chamber into the air chamber 91 and the balancing chamber 92, wherein the balancing chamber 92 is connected to the outside and is always kept open to the atmospheric pressure. The elastic diaphragm 6 can be made of elastic materials such as silicone and rubber, and can be elastically deformed in the direction toward the inside of the air chamber 91. When the air pressure in the air chamber 91 is less than the air pressure in the balancing chamber 92, the elastic diaphragm 6 is affected by the air pressure in the balancing chamber 92, and the elastic diaphragm 6 is deformed toward the inside of the air chamber 91, and the middle area of ​​the elastic diaphragm 6 moves toward the inside of the air chamber 91, thereby driving the piston member 4 to move; when the air pressure in the air chamber 91 and the balancing chamber 92 is balanced, the elastic diaphragm 6 is deformed and restored under the action of its own elastic force, and the middle area of ​​the elastic diaphragm 6 moves and resets in the direction away from the inside of the air chamber 91, thereby driving the piston member 4 to move. The middle area of ​​the elastic diaphragm 6 constitutes a movable part.

[0047] The elastic membrane 6 can be square, round, irregular, etc., which is not limited in the present application. The elastic membrane 6 can be deformed and restored by its own elastic force, without the need for additional auxiliary components, and has a simple structure and low cost.

[0048] The specific shapes of the air cavity 91 and the balance cavity 92 can be cylindrical, square, irregular, etc., and the present application does not limit their specific structures as long as they can accommodate air. Similarly, the specific shape of the shell can be tubular, cylindrical, irregular, etc., and can be an integrated structure or a structure formed by a combination of multiple components. The present application does not limit its specific structure as long as it can form a water inlet channel and a containing cavity inside.

[0049] See also Figure 2 In some embodiments, the housing includes a first housing 24 and a second housing 25. Figure 3 and Figure 4 As shown, the first shell 24 defines the water inlet channel, and a mounting groove 26 is formed at one end of the first shell 24, and a through hole 27 is provided on the groove wall of the mounting groove 26; the elastic diaphragm 6 is sealed and installed in the notch of the mounting groove 26 to define the balance cavity 92 with the first shell 24, and the through hole 27 connects the balance cavity 92 with the outside; the second shell 25 is sealed and installed on the side of the elastic diaphragm 6 away from the first shell 24 to enclose and define the air cavity 91 with the elastic diaphragm 6. The shell is composed of the first shell 24 and the second shell 25, and the elastic diaphragm 6 is sandwiched between the first shell 24 and the second shell 25. Specifically, the periphery of the elastic diaphragm 6 is fixed between the first shell 24 and the second shell 25.

[0050] See also Figure 1 In some embodiments, the water inlet channel includes a first pipe 21 and a second pipe 22 that intersect and communicate with each other; one end of the second pipe 22 away from the first pipe 21 is communicated with the venturi tube 3; the first pipe 21 extends along the first direction 8, and the first pipe 21 includes a first section 211 and a second section 212 that are sequentially arranged in a direction close to the second pipe 22, the inner diameter of the first section 211 is larger than the inner diameter of the second section 212, the first section 211 is used to connect to a water supply device, and the second section 212 is used to connect to the second pipe 22. The piston member 4 can be reciprocated in the first pipe 21 along the first direction 8, and has an open position located in the first section 211 to open the water inlet channel and a closed position located in the second section 212 to close the water inlet channel. When the piston member 4 is in the open position, a gap is formed between the piston member 4 and the inner wall of the first section 211, and water can flow into the second section 212 from the gap. When the piston member 4 is in the closed position, the piston member 4 is sealed with the inner wall of the second section 212, so that water cannot flow through the second section 212.

[0051] See also Figure 7In some embodiments, the piston member 4 is further provided with a sealing ring 5, which is wound around the piston member 4. When the piston member 4 is in the open position, a gap is formed between the sealing ring 5 and the inner wall of the first section 211. When the piston member 4 is in the closed position, the sealing ring 5 is sealed with the inner wall of the second section 212. The piston member 4 is generally cylindrical, and its shape matches the shape of the pipe of the second section 212. The sealing ring 5 can be made of elastic materials such as silicone and rubber, and the sealing ring 5 helps to improve the sealing effect between the piston member 4 and the inner wall of the second section 212.

[0052] In order to prevent the piston member 4 from going off course when moving, a plurality of guide ribs 23 extending along the first direction 8 are provided on the inner wall of the first section 211. The plurality of guide ribs 23 are arranged at intervals along the circumference of the first section 211. The plurality of guide ribs 23 define a first guide channel for guiding the piston member 4 to move along the first direction 8. Thus, when the piston member 4 moves into the first section 211, with the assistance of the first guide channel, the piston member 4 can reciprocate along the channel direction, i.e., the first direction 8, to avoid the defect of being unable to return to the second section 212 due to the deviation path. At the same time, the plurality of guide ribs 23 are arranged at intervals, so that a gap space can still be left between the piston member 4 and the inner wall of the first section 211, thereby avoiding the influence on water inflow.

[0053] In some embodiments, the groove depth direction of the mounting groove 26 is consistent with the first direction 8, so that the central axis direction of the elastic diaphragm 6 installed on the groove will be consistent with the first direction 8, so that the middle area of ​​the elastic diaphragm 6 can move along the first direction 8. In this way, the moving direction of the movable part is consistent with the target moving direction of the piston part 4, and linear drive can be achieved. When the movable part moves, it can smoothly drive the piston part 4 to move along the first direction 8.

[0054] There are many ways to drive the piston 4, such as magnetic drive, mechanical drive, etc. Figure 1As shown, in some embodiments, the first direction 8 is the up-down direction; the laundry processing device 100 further includes a first magnetic member 71 and a second magnetic member 72 that repel each other magnetically, the first magnetic member 71 being arranged on the movable member, the second magnetic member 72 being arranged on the piston member 4, and the second magnetic member 72 being located above the first magnetic member 71. In the initial state, due to the repulsive force between the first magnetic member 71 and the second magnetic member 72, the piston member 4 and the second magnetic member 72 can enter the first section 211, so that the water inlet channel remains unobstructed; when the air pressure in the air cavity 91 changes and the movable member moves into the air cavity 91 along the first direction 8, the distance between the first magnetic member 71 and the second magnetic member 72 becomes larger, the repulsive force becomes smaller, and the second magnetic member 72 moves downward under the force of gravity and the water flow, thereby driving the piston member 4 to move to the closed position and cutting off the water flow.

[0055] See also Figure 5 and Figure 6 When the movable part is set as the middle area of ​​the elastic diaphragm 6, a mounting seat 61 is also provided on the middle area of ​​the elastic diaphragm 6, and the first magnetic member 71 can be installed on the mounting seat 61. In some embodiments, the mounting seat 61 includes a seat body for mounting on the elastic diaphragm 6 and a cylinder formed on one side of the seat body, and an installation space is formed in the cylinder body, and the first magnetic member 71 can be installed in the installation space. Furthermore, a protrusion 62 is also provided on the elastic diaphragm 6, and a mounting hole 63 or a groove is provided on the seat body corresponding to the protrusion 62. The assembly of the seat body and the cylinder body is achieved by the mutual cooperation between the protrusion 62 and the mounting hole 63, or the protrusion 62 and the groove.

[0056] In some embodiments, a guide structure extending along the first direction 8 is provided in the mounting groove 26, and the guide structure defines a limiting structure 28 extending along the first direction 8. The limiting structure 28 is located on a side of the first magnetic member 71 close to the second magnetic member 72 to position the first magnetic member 71 in the first direction 8. When the movable member is reset, the limiting structure 28 can abut the movable member to limit its continued movement toward the second magnetic member 72.

[0057] Furthermore, the guide structure can be set as a cylinder, in which a cavity for accommodating the first magnetic part 71 is formed. When the movable part is reset in the direction close to the second magnetic part 72, the first magnetic part 71 can be inserted into the cavity, which can guide the reset direction of the movable part to a certain extent and prevent the first magnetic part 71 from tilting. When the movable part moves to the initial position, the end of the cylinder away from the bottom of the installation groove 26 abuts against the movable part, which can play a role in positioning and limiting the movable part.

[0058] In some embodiments, in order to prevent the cavity from forming a closed space and affecting the movement of the movable parts, a through hole 29 can be provided on the side wall of the cylinder to connect the space inside and outside the cylinder.

[0059] In some embodiments, the bottom of the mounting groove 26 is provided with a mounting opening connected to the first pipe 21; the clothing processing device 100 further includes a connecting rod extending along the first direction 8, the connecting rod is inserted into the mounting opening, and slides and seals with the inner wall of the mounting opening, one end of the connecting rod is connected to the piston member 4, and the other end is connected to the movable member. In this way, when the movable member moves along the first direction 8, the connecting rod can synchronously drive the piston member 4 to move along the first direction 8. Among them, the outer wall of the connecting rod and the inner wall of the mounting opening can be set to a smooth surface to ensure better sealing and cooperation between the two.
