Description

Technical Field

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

[0002] Washing machines and other clothing processing equipment are cleaning appliances that use electrical energy to create mechanical action to wash clothes.

[0003] With the continuous development of social economy, people's requirements for quality of life are also constantly improving. Existing clothing processing equipment takes a long time to wash without heating and has poor cleaning effect. A washing machine is provided in the related art, which adopts internal circulation spraying technology to circulate and spray the liquid in the inner drum and outer drum of the washing machine to the inner drum, thereby improving the cleaning effect and meeting people's needs.

[0004] However, the drainage pump of the existing washing machine cannot simultaneously satisfy the external drainage function and the internal circulation spraying function of the washing machine. Utility Model Content

[0005] The purpose of this application is to at least solve the above-mentioned problems.

[0006] The purpose of the present application is also to reduce the production cost of clothing processing equipment.

[0007] The purpose of the present application is also to block the reflux channel of residual water in the drain pipe, thereby ensuring the washing effect of the clothing processing equipment.

[0008] The purpose of the present application is not limited to the above-mentioned purpose, and those skilled in the art can clearly understand other purposes not mentioned through the following description.

[0009] The clothes treating apparatus of the present application for achieving the above-mentioned object includes a housing.

[0010] The clothes processing device comprises an outer drum which is arranged in a shell.

[0011] The clothing processing device comprises an inner drum which is rotatably arranged in an outer drum and has a clothing washing cavity which is communicated with the cavity of the outer drum.

[0012] The laundry processing device comprises a drainage pump which is located in the housing and communicated with the outer tub.

[0013] The laundry processing device comprises a drain pipe, a part of which is arranged in a housing, and another part of which is arranged outside the housing.

[0014] The clothes processing device comprises a circulation pipeline which is arranged in the shell, and a water outlet end of the circulation pipeline is configured to communicate with a spray head which faces the drum opening of the inner drum.

[0015] The clothing processing device includes a connecting device. The connecting device includes a mounting seat, a moving part and a blocking member. The mounting seat has a connecting cavity and a first connecting port, a second connecting port and a third connecting port connected to the connecting cavity. Along the first direction, the first connecting port and the second connecting port are spaced apart on the circumferential side wall of the mounting seat, and the third connecting port is arranged at the end of the mounting seat. Among them, the first connecting port is connected to the water outlet end of the drainage pump, the second connecting port is connected to the water inlet end of the circulation pipeline, and the third connecting port is connected to the water inlet end of the drainage pipe. The blocking member is sleeved on the outside of the moving part and is arranged in the connecting cavity with the moving part. Along the first direction, the blocking member and the third connecting port are arranged opposite to each other. The first direction is parallel to the length direction of the mounting seat.

[0016] The clothes processing device includes a control device. The control device includes a control member connected to the moving member. The control member is used to control the moving member to move toward or away from the third connecting port, so as to drive the blocking member to move simultaneously in the connecting cavity, so as to connect the first connecting port with the second connecting port or the third connecting port.

[0017] The laundry processing device provided in the embodiment of the present application is provided with a connecting device and a control device. The connecting device includes a moving part and a blocking part. The control device includes a control part. Under the control of the control part, the moving part can drive the blocking part to move in the connecting cavity to selectively connect the first connecting port with the second connecting port or the third connecting port, thereby realizing the connection between the water outlet of the drainage pump and the water inlet of the circulation pipeline, or the water outlet of the drainage pump and the water inlet of the drainage pipe.

[0018] When the water outlet of the drain pump is connected to the water inlet of the circulation pipeline, the drain pump can pump the liquid in the inner and outer drums into the circulation pipeline, so as to realize the internal circulation spraying function of the clothing processing equipment, improve the washing effect or the rinsing effect, and then improve the cleaning effect, and it has the characteristics of saving time and water. When the water outlet of the drain pump is connected to the water inlet of the drain pipe, the drain pump can pump the liquid in the inner and outer drums into the drain pipe, so as to realize the external drainage function of the clothing processing equipment.

[0019] The clothes processing device of the embodiment of the present application is provided with a control device and a control device, so that the clothes processing device can simultaneously satisfy the external drainage function and the internal circulation spraying function of the clothes processing device on the basis of a drainage pump, thereby improving the washing effect of the clothes processing device. The embodiment of the present application does not require the drainage pump to have the function of bidirectional rotation, and does not require the introduction of a circulation pump. At the same time, due to the simple structure of the connecting device and the control device, the clothes processing device of the embodiment of the present application can simultaneously satisfy the external drainage function and the internal circulation spraying function of the clothes processing device, and can also reduce the manufacturing cost of the clothes processing device.

[0020] Furthermore, by limiting the positions of the first connecting port, the second connecting port and the third connecting port, the first connecting port can be selectively connected to the second connecting port and the third connecting port by moving the moving part along the first direction, so as to simplify the movement of the moving part and ensure the sealing effect of the blocking part.

[0021] In some embodiments, when the clothing processing device performs a clothing processing program, the blocking piece is located at the third connecting port, and the blocking piece can block the third connecting port to connect the first connecting port with the second connecting port to prevent the liquid in the inner drum and the outer drum from entering the third connecting port and affecting the internal circulation spraying effect and the washing effect of the clothing processing device.

[0022] In some embodiments, after the laundry processing program of the laundry processing device is finished, the blocking member is located at the third communication port, and the blocking member can block the third communication port to connect the first communication port with the second communication port. The blocking member can block the reflux channel of the residual water in the drain pipe to prevent the residual water from reflux into the outer drum or even the inner drum, causing odor in the laundry processing device, thereby ensuring the washing effect of the laundry processing device.

[0023] When the clothing processing device is draining water externally, the blocking member is located between the first connecting port and the second connecting port, and the blocking member abuts against the inner wall of the mounting seat to connect the first connecting port and the third connecting port, so that the liquid in the inner drum and the outer drum can only be pumped into the drain pipe by the drainage pump. At the same time, the lint in the liquid is not easy to block the first connecting port and the third connecting port, thereby enhancing the practicality of the connecting device in the clothing processing device.

[0024] In some embodiments, the moving part is constructed to be able to move relative to the control device in a first direction under the traction force of the control part, so that the blocking part can be driven by the moving part to move simultaneously in the first direction, so that the blocking part can be located at the third connecting port, or between the first connecting port and the second connecting port, so as to selectively connect the first connecting port with the second connecting port or the third connecting port.

[0025] In some embodiments, one end of the blocking member adjacent to the third communication port is a blocking end portion, and along the first direction, the blocking end portion is opposite to the third communication port;

[0026] When the moving part moves relative to the control device along the first direction under the traction of the control part, it can drive the blocking end to move simultaneously along the first direction in the connecting cavity to connect the first connecting port with the second connecting port or the third connecting port, thereby selectively connecting the first connecting port with the second connecting port or the third connecting port to realize the internal circulation spraying function or external drainage function of the clothing processing equipment.

[0027] In some embodiments, when the blocking end moves along the first direction to the third connecting port, the blocking end can block the third connecting port to connect the first connecting port with the second connecting port, so that the drainage pump can pump the liquid in the inner drum and the outer drum into the circulation pipeline, thereby realizing the internal circulation spray function of the clothing processing equipment.

[0028] In some embodiments, when the blocking end moves along the first direction to between the first connecting port and the second connecting port, the blocking end abuts against the inner wall of the mounting seat to connect the first connecting port and the third connecting port, so that the drainage pump can pump the liquid in the inner drum and the outer drum into the drain pipe, thereby realizing the external drainage function of the clothing processing equipment.

[0029] In some embodiments, the blocking end portion has a first blocking portion and a second blocking portion, the first blocking portion is located in the circumference of the blocking end portion, and the second blocking portion is located on the end surface of the blocking end portion;

[0030] When the blocking end moves along the first direction to the third connecting port, the first blocking portion and the second blocking portion are both located on the peripheral side of the third connecting port and abut against the inner wall of the mounting seat at the same time, so as to realize double blocking of the third connecting port by the blocking end through the first blocking portion and the second blocking portion, thereby enhancing the blocking effect of the blocking end on the third connecting port.

[0031] In some embodiments, when the blocking end moves along the first direction to between the first communication port and the second communication port, the first blocking portion abuts against the inner wall of the mounting seat, so that the first blocking portion can block between the first communication port and the second communication port to prevent the first communication port from communicating with the second communication port. At the same time, it can ensure that the first communication port and the third communication port are not blocked by the blocking member and are in a completely open state. In this way, when the liquid flows from the first communication port to the third communication port, the wire scraps in the liquid are not easy to block the first communication port and the third communication port, so as to ensure that the liquid of the drainage pump can be smoothly discharged to the outside of the shell through the drainage pipe.

[0032] In some embodiments, the end surface of the blocking end portion further has a third blocking portion, and the shape of the third blocking portion matches the shape of the third communication port.

[0033] When the blocking end moves to the third communicating port along the first direction, at least a portion of the third blocking portion is located in the third communicating port to block the third communicating port, thereby further enhancing the blocking effect of the blocking end on the third communicating port.

[0034] In some embodiments, the blocking end is a flexible structure with a cavity. The end of the moving part is inserted into the cavity, so that the blocking end can be inserted into the blocking end to drive the blocking end to move, and at the same time, the blocking end can be deformed to achieve the first blocking part and the second blocking part abutting against the inner wall of the mounting seat.

[0035] In some embodiments, a support portion is provided on the end of the moving part. The shape of the support portion matches the shape of the cavity. The support portion is supported on the inner wall of the cavity to ensure the stability of the structure and shape of the blocking end, so as to avoid the blocking effect of the blocking end from failing after the clothing processing device is used for a long time.

[0036] In some embodiments, along the first direction, the blocking piece has a middle section on a side of the blocking end portion facing the control device.

[0037] The outer diameter of the middle section is smaller than the outer diameter of the sealing end, so that along the first direction, the sealing part is located in the middle section with an inwardly retracted structure, so that the first connecting port is as completely open as possible, so that the wire scraps in the liquid are not likely to block the first connecting port and the second connecting port, thereby ensuring that the liquid in the drainage pump can be smoothly circulated to the inner cylinder through the circulation pipeline.

[0038] In some embodiments, the communication device further comprises an end cap, which is arranged at an end of the mounting seat away from the third communication port to seal the communication cavity.

[0039] The moving part is arranged in the end cover and connected with the control part. One end of the blocking part adjacent to the end cover is a fixed end, which is installed on the side of the end cover facing the communication cavity, so that the blocking part can be installed in the communication cavity through the end cover.

[0040] In some embodiments, the communication device further includes an elastic member, which is sleeved on the moving member and located between the moving member and the blocking member.

[0041] One end of the elastic member abuts against the moving member, and the other end abuts against a side of the end cover facing the communicating cavity, so that the moving member and the blocking end can be automatically reset under the rebound force of the elastic member.

[0042] In some embodiments, the fixed end is a telescopic structure that can be telescoped along the first direction. When the elastic member telescopes, the fixed end can also telescope synchronously to ensure that the blocking end can move along the first direction toward or away from the third communication port under the drive of the moving member.

[0043] In some embodiments, the control device is a tractor, and the control member is a traction rope, so that the control member is pulled by the wire rope to control the movement of the control member.

[0044] In some embodiments, the moving part is sleeved on the outside of the control part, and is constructed to be able to rotate around the control part and move relative to the control device in a first direction when the control part rotates, so as to drive the blocking part to rotate and move at the same time, and selectively connect the first connecting port with the second connecting port and the third connecting port, so as to realize the circulating spray function or external drainage function of the clothing processing equipment.

[0045] In some embodiments, the moving part is sleeved on the outside of the control part and is threadedly connected to the control part, so that when the control part rotates, the moving part rotates around the control part and can also make linear motion along the axial direction of the control part, thereby driving the blocking part to rotate and move at the same time. In addition, by changing the rotation direction of the control part, the moving part and the blocking part can be automatically reset without the need for an elastic part.

[0046] In some embodiments, the control device is a motor, and the control element is a rotating shaft of the motor.

[0047] In some embodiments, the blocking piece has a first blocking portion and a second blocking portion, the first blocking portion is located in the circumference of the blocking piece, and the second blocking portion is located on the end surface of the blocking piece.

[0048] When the blocking member moves along the first direction to the third communication port, at least one of the first blocking portion and the second blocking portion abuts against the inner wall of the mounting seat around the third communication port to block the third communication port and connect the first communication port and the second communication port.

[0049] When the blocking member moves along the first direction to between the first communication port and the second communication port, the first blocking portion abuts against the circumferential inner wall of the mounting seat to block between the first communication port and the second communication port, and at the same time, connects the first communication port and the third communication port.

[0050] In some embodiments, the control device is sealedly connected to an end of the mounting seat away from the third connecting port to ensure smooth operation of the internal circulation spraying and external drainage functions of the clothing processing equipment.

[0051] In some embodiments, the clothing treatment device further comprises a one-way valve. The one-way valve is arranged at the water inlet end of the drainage pump or the drainage outlet of the outer drum, and is configured to connect the drainage outlet of the outer drum with the water inlet end of the drainage pump under the pressure of the liquid in the outer drum, so as to ensure that the internal circulation spraying function or the external drainage function of the clothing treatment device is realized, and at the same time, the refluxed residual water can be further blocked outside the outer drum, thereby realizing secondary blocking of the residual water.

[0052] In some embodiments, the clothing processing device further comprises a door body. The door body is connected to the housing. The housing is provided with a clothing access opening, the outer drum is arranged in the housing, and the drum opening of the outer drum faces the clothing access opening. The door body is used to cover the clothing access opening.

[0053] In some embodiments, the clothes processing device further comprises a door seal, which is arranged between the tube opening of the outer drum and the door body.

[0054] In some embodiments, the clothes treating device further comprises a shower head, which is mounted on the door seal and located on a side of the door seal facing the top of the housing, so as to realize the installation of the shower head in the housing. BRIEF DESCRIPTION OF THE DRAWINGS

[0151] The embodiment of the present application provides a clothes processing device, which may include a washing machine, a shoe washer, or other washing device capable of washing clothes and objects. For example, the washing machine may be a drum washing machine or a pulsator washing machine.

[0152] Figure 1 The structure diagram of a clothes processing device 10 in an internal circulation state is schematically shown. Figure 1 The laundry processing device 10 is a drum washing machine. Figure 1 Taking a drum washing machine as an example, the structure of the clothes processing device 10 is further described.

[0153] See also Figure 1 As shown, the laundry processing device 10 may include a housing 20. The housing 20 is provided with a laundry taking-in and putting-out opening.

[0154] The laundry processing apparatus 10 may include an outer drum 40. The outer drum 40 is disposed in the housing 20, and the drum opening of the outer drum 40 faces the laundry taking-in and putting-out opening.

[0155] The clothing processing device 10 may include an inner drum 50. The inner drum 50 is rotatably disposed in the outer drum 40, and the tube mouth of the inner drum 50 is also facing the clothing loading and unloading port. The inner drum 50 has a clothing washing cavity. During the process of washing clothes, the inner drum 50 can rotate relative to the outer drum 40 to wash the clothes in the clothing washing cavity. The clothing washing cavity is connected to the cavity of the outer drum 40. For example, a plurality of through holes can be opened on the inner drum 50, and the plurality of through holes can be evenly distributed on the wall of the inner drum 50. The water in the clothing washing cavity can flow into the outer drum 40 through the through holes on the wall of the inner drum 50, and can be discharged from the outer drum 40 after the washing is completed.

[0156] See also Figure 1As shown, the laundry processing device 10 may further include a door body 30. The door body 30 is connected to the housing 20 to cover the laundry access opening. For example, the door body 30 may be provided at the laundry access opening and rotatably connected to the housing 20 so that the door body 30 can cover the laundry access opening, and at the same time, the door body 30 can be easily opened so that the laundry can be put into the inner drum 50 through the laundry access opening, and the laundry can be washed by the laundry processing device 10.

[0157] See also Figure 1 As shown, the clothes treating apparatus 10 may further include a door seal 60. The door seal 60 is disposed between the tube opening of the outer drum 40 and the door body 30 to seal the gap between the door body 30 and the tube opening of the outer drum 40. Specifically, the door body 30 may be a glass door body so that the user can observe the condition of the clothes in the inner drum 50 through the door body 30.

[0158] The laundry processing device 10 may further include a water inlet pipeline (not shown). A portion of the water inlet pipeline may be disposed inside the housing 20, and another portion may be disposed outside the housing 20, so that the water inlet pipeline is connected to an external water source (such as a faucet). Water is injected into the inner drum 50 through the water inlet pipeline, and at the same time, the water flowing through the water inlet pipeline may bring detergent into the inner drum 50, so that the laundry processing device 10 can wash the laundry with the cooperation of water and detergent.

[0159] See also Figure 1 As shown, the laundry treatment apparatus 10 may further include a drain pipe 80. A portion of the drain pipe 80 is disposed inside the housing 20, and another portion is disposed outside the housing 20, so as to drain liquid to the outside of the housing 20.

[0160] The clothes treating apparatus 10 may further include a drain pump 70. The drain pump 70 is disposed in the housing 20 and may be connected to the outer tub 40 so that the liquid in the outer tub 40 can enter the outer tub 40, and the drain pump 70 can pump the liquid in the outer tub 40 into the drain pipe 80. The water inlet end of the drain pump 70 may be connected to the drain port of the outer tub 40 to achieve the connection between the drain pump 70 and the outer tub 40.

[0161] The clothing treatment device 10 has a clothing treatment program. Among them, the clothing treatment program includes a washing program, a rinsing degree, etc. In the clothing treatment program, the drain pump 70 is used to pump the liquid in the inner drum 50 and the outer drum 40 into the drain pipe 80, so as to discharge the liquid to the outside of the housing 20 through the drain pipe 80, thereby realizing the external drainage function of the clothing treatment device 10. Specifically, when the clothing treatment program is a washing program, the liquid in the inner drum 50 and the outer drum 40 can be a liquid formed by a mixture of water and detergent. When the clothing treatment program is a rinsing degree, the liquid in the inner drum 50 and the outer drum 40 can be water, or a mixed liquid formed by a mixture of water and a whitening agent, etc.

[0162] It should be noted that when the clothing processing device 10 is running, the inner drum 50 can rotate, and the liquid in the inner drum 50 can enter the outer drum 40 through the through holes on the drum wall of the inner drum 50, so as to enter the drain pump 70 through the drain port of the outer drum 40, so that the drain pump 70 can pump the liquid in the inner drum 50 and the outer drum 40 into the drain pipe 80.

[0163] In some embodiments, the clothing processing device 10 may further include a heater, which can heat the water in the inner drum 50 so as to realize the function of heating and washing clothing by the clothing processing device 10 and improve the cleaning effect of the clothing processing device 10 on clothing.

[0164] However, the existing clothes processing equipment takes a long time to wash clothes without heating and has poor washing effect.

[0165] For this purpose, a circulation pipeline and a spray head are also provided in the clothes processing device in the related art. When the clothes processing device is in a clothes processing program, and the clothes processing program is a washing program, the circulation pipeline can introduce the liquid discharged from the inner drum 50 and the outer drum 40 into the spray head, and the liquid can be sprayed into the inner drum 50 through the spray head, and the liquid is sprayed onto the clothes in the inner drum 50, so that the clothes can be effectively rinsed, thereby effectively soaking the clothes, realizing the internal circulation spraying function of the clothes processing device, improving the washing effect, and then improving the cleaning effect, and at the same time, it has the characteristics of saving time and water.

[0166] Similarly, when the clothing processing equipment is in the clothing processing program, and the clothing processing program is a rinsing program, the internal circulation spray function of the clothing processing equipment can also be realized through the circulation pipeline to improve the rinsing effect, and then improve the cleaning effect, and it has the characteristics of saving time and water.

[0167] Since the drainage pumps of existing clothing processing equipment mostly use traditional unidirectional rotary drainage pumps, the drainage pumps can only rotate in one direction, and such drainage pumps cannot simultaneously satisfy the external drainage function and the internal circulation spraying function of the clothing processing equipment. If a bidirectional drainage pump is used, although the external drainage function and the internal circulation spraying function of the clothing processing equipment can be satisfied by rotating the bidirectional drainage pump in two different directions (such as forward or reverse), the manufacturing cost of such a bidirectional drainage pump is higher than that of a unidirectional rotary drainage pump, which will increase the manufacturing cost of the clothing processing equipment.

[0168] To this end, a circulation pump is added to the clothes processing device in the related art, and the liquid in the inner drum 50 and the outer drum 40 can be pumped into the circulation pipeline through the circulation pump, thereby realizing the above-mentioned function of the circulation pipeline.

[0169] However, the introduction of the circulation pump will cause the clothing processing device to have both a drainage pump 70 and a circulation pump. Although this can slightly save the manufacturing cost of the clothing processing device compared to a two-way drainage pump, the manufacturing cost is still higher than that of a clothing processing device with only a unidirectional rotating drainage pump.

[0170] Therefore, how to satisfy the external drainage function and the internal circulation spraying function of the clothing processing device 10 at a lower manufacturing cost has become a technical problem to be solved.

[0171] Figure 2 Schematically shows Figure 1 Schematic diagram of the structure of the clothes processing device 10 in the external drainage state. Figure 3 Schematically shows Figure 1 Schematic diagram of the structure of the clothes processing device 10 after the external drainage is completed.

[0172] In view of this, see Figures 1 to 3 As shown, in the clothing treatment device 10 provided in the embodiment of the present application, a connecting device 200 and a control device 300 are additionally provided, the connecting device 200 has a mounting seat 210 and a blocking member 230, and the mounting seat 210 has three connecting ports. The three connecting ports can respectively connect the water inlet end of the drain pump 70, the water inlet end of the drain pipe 80, and the water inlet end of the circulation pipeline 90. Under the control of the control device 300, the blocking member 230 can move in the mounting seat 210 to connect the water inlet end of the drain pump 70 with the water inlet end of the drain pipe 80 or the water inlet end of the circulation pipeline 90, so that the external drainage function and the internal circulation spraying function of the clothing treatment device 10 can be met through the cooperation of a drain pump 70 with the connecting device 200 and the control device 300. At the same time, compared with the clothing treatment device 10 (adding a circulation pump) in the related art mentioned above, or the method of setting a bidirectional drainage pump, the present application can also reduce the manufacturing cost of the clothing treatment device 10.

[0173] This will be further described below with reference to the accompanying drawings and specific embodiments.

[0174] Figure 4 Indicated Figure 1 Enlarged view at a1. Figure 4 As shown, in some embodiments, the laundry treating apparatus 10 may include a communication device 200 .

[0175] The communication device 200 may include a mounting seat 210. The mounting seat 210 has a communication cavity 211 and three communication ports communicating with the communication cavity 211. For ease of description, the three communication ports are defined as a first communication port 212, a second communication port 213, and a third communication port 214, respectively.

[0176] Along the first direction, the first communication port 212 and the second communication port 213 may be spaced apart on the circumferential sidewall of the mounting seat 210, and the third communication port 214 may be disposed at the end of the mounting seat 210. The first direction is parallel to the length direction of the mounting seat 210, specifically, see the X direction.

[0177] The first communication port 212 can be communicated with the water outlet of the drain pump 70. The second communication port 213 can be communicated with the water inlet of the circulation pipeline 90. The third communication port 214 can be communicated with the water inlet of the drain pipe 80. The mounting base 210 is connected with the water outlet of the drain pump 70, the water inlet of the circulation pipeline 90, and the water inlet of the drain pipe 80 through these three communication ports.

[0178] The communication device 200 may further include a blocking member 230. The communication device 200 may further include a moving member 220. The blocking member 230 may be sleeved on the outside of the moving member 220 and disposed in the communication cavity 211 together with the moving member 220 to achieve installation of the blocking member 230 and the moving member 220 in the mounting seat 210. In the first direction, the blocking member 230 is opposite to the third communication port 214.

[0179] It should be noted that, the phrase "A and B are opposite to each other in a certain direction" mentioned in the present application can be understood as A and B are arranged opposite to each other in a certain direction. The arrangement of A and B opposite to each other does not mean that the center of A and the center of B are absolutely opposite to each other. If conditions permit, the center of A and the center of B may be slightly offset in the first direction. For example, "the blocking member 230 and the third connecting port 214 are opposite to each other in the first direction" can be understood as the center of the blocking member 230 and the center of the third connecting port 214 may be opposite to each other in the first direction, or, without affecting the sealing of the third connecting port 214 and other connecting ports by the blocking member 230, the center of the blocking member 230 and the center of the third connecting port 214 may be slightly offset in the first direction. If there are similar descriptions below, they can be understood in this way.

[0180] See also Figure 4 As shown, in some embodiments, the laundry processing device 10 may further include a control device 300. The control device 300 may include a control member 310 connected to the moving member 220. The control member 310 is used to control the moving member 220 to move toward or away from the third communication port 214, so as to drive the blocking member 230 to move simultaneously in the communication cavity 211, so as to connect the first communication port 212 with the second communication port 213 or the third communication port 214.

[0181] In this way, the moving part 220 can drive the blocking part 230 to move in the connecting cavity 211 under the control of the control part 310, so as to selectively connect the first connecting port 212 with the second connecting port 213 or the third connecting port 214, thereby realizing the connection between the water outlet end of the drainage pump 70 and the water inlet end of the circulation pipeline 90, or the water outlet end of the drainage pump 70 and the water inlet end of the drainage pipe 80.

[0182] See also Figure 4 As shown, when the clothes processing device 10 is in the clothes processing program, the blocking member 230 can be controlled by the control member 310 to control the moving member 220, so that the water outlet of the drain pump 70 is connected with the water inlet of the circulation pipeline 90. At this time, the drain pump 70 can pump the liquid in the inner drum 50 and the outer drum 40 into the circulation pipeline 90, so as to realize the internal circulation spraying function of the clothes processing device 10, improve the washing effect or the rinsing effect, and then improve the cleaning effect, and have the characteristics of saving time and water.

[0183] Figure 5 Indicated Figure 1 Enlarged view at a2. Figure 5 As shown, when the laundry treatment program of the laundry treatment device 10 ends, the blocking member 230 can be controlled by the control member 310 to control the moving member 220, so that the water outlet of the drain pump 70 is connected to the water inlet of the drain pipe 80. At this time, the drain pump 70 can pump the liquid in the inner drum 50 and the outer drum 40 into the drain pipe 80, so as to realize the external drainage function of the laundry treatment device 10.

[0184] Therefore, the clothing processing device 10 of the embodiment of the present application, through the setting of the control device 300 and the control device 300, enables the clothing processing device 10 to simultaneously meet the external drainage function and the internal circulation spraying function of the clothing processing device 10 on the basis of a drainage pump 70, thereby improving the washing effect of the clothing processing device 10.

[0185] Furthermore, the embodiment of the present application does not require the drain pump 70 to have the bidirectional rotation function, and the drain pump 70 may be a traditional unidirectional rotation drain pump, which can reduce the manufacturing cost of the clothing processing device 10 compared to a bidirectional drain pump.

[0186] At the same time, since the connecting device 200 and the control device 300 have a simple structure and have a lower manufacturing cost than a circulating pump, the present application can also reduce the manufacturing cost of the clothing processing equipment 10 compared to the clothing processing equipment with a circulating pump in the related technology mentioned above.

[0187] Furthermore, by limiting the positions of the first connecting port 212, the second connecting port 213 and the third connecting port 214, the first connecting port 212 can selectively connect the second connecting port 213 and the third connecting port 214 by moving the moving part 220 along the first direction, so as to simplify the movement of the moving part 220 and ensure the blocking effect of the blocking part 230.

[0188] It should be understood that when the laundry treatment program is a washing program, the present application can improve the washing effect of the laundry treatment device 10. When the laundry treatment program is a rinsing program, the present application can improve the rinsing effect of the laundry treatment device 10.

[0189] The structure of the clothing processing device 10 is further described below by taking the clothing processing program as a washing program as an example.

[0190] See also Figure 1 As shown, in some embodiments, the clothing processing device 10 may further include a spray head 120. The spray head 120 may be connected to the water outlet end of the circulation pipeline 90, and the spray head 120 may face the inner drum 50, so that when the drainage pump 70 pumps the liquid into the circulation pipeline 90, the liquid in the circulation pipeline 90 can be sprayed to the inner drum 50 through the spray head 120, thereby spraying the liquid to the clothing in the inner drum 50, realizing the internal circulation spraying function of the clothing processing device 10, improving the washing effect, and then improving the cleaning effect, and having the characteristics of saving time and water.

[0191] At the same time, the liquid sprayed into the inner drum 50 by the spray head 120 can also rinse the inner drum 50, the door seal 60, the door body 30, etc., to prevent impurities such as foam generated by the detergent from remaining in the inner drum 50 and the door body 30, thereby ensuring the cleaning effect of the clothes and the health of the user.

[0192] In some embodiments, the spray head 120 can be installed on the door seal 60 and located on the side of the door seal 60 facing the top of the housing 20 to achieve the installation of the spray head 120 in the housing 20. When the spray head 120 is installed on the door seal 60, it can be rotated, swung, etc. relative to the door seal 60 to expand the spraying area of ​​the spray head 120. Alternatively, by optimizing the spray head 120, when the spray head 120 is fixed relative to the door seal 60 (i.e., not rotating or swinging), the spraying area of ​​the spray head 120 can also be expanded. This will be further explained later and will not be repeated here.

[0193] The drain pump 70, the connecting device 200, the control device 300 and the circulation pipeline 90 can all be arranged in the shell 20 to realize the connection between the three connecting ports of the mounting seat 210 and the water outlet end of the drain pump 70, the water inlet end of the circulation pipeline 90 and the water outlet end of the drain pipe 80 respectively. At the same time, the connection between the control component 310 and the moving component 220 can be realized so that the movement of the moving component 220 can be controlled by the control component 310.

[0194] See also Figure 4 As shown, when the communication device 200 and the control device 300 are arranged in the housing 20, the communication device 200 and the mounting seat 210 can be installed at the bottom of the housing 20. Among them, when the mounting seat 210 is installed at the bottom of the housing 20, the length direction of the mounting seat 210 can be parallel to the placement platform (such as the ground) of the clothing processing device 10, so that when the communication device 200 is installed at the bottom of the housing 20, in the height direction of the clothing processing device 10, the installation space occupied by the communication device 200 in the housing 20 can be compressed, so that when the height of the housing 20 remains unchanged, the processing capacity of the clothing processing device 10 on the clothing can be increased.

[0195] It should be noted that the height direction of the laundry processing device 10 is perpendicular to the first direction (X direction). When the laundry processing device 10 is placed on the placement platform, the height direction of the laundry processing device 10 can be understood as the direction in which the laundry processing device 10 is perpendicular to the placement platform.

[0196] See also Figure 4 As shown, when the laundry processing apparatus 10 performs a laundry processing program, the blocking member 230 may be located at the third communication port 214 , and the blocking member 230 may block the third communication port 214 to connect the first communication port 212 with the second communication port 213 .

[0197] In this way, when the clothing processing device 10 performs a clothing processing program, the first connecting port 212 is connected to the second connecting port 213. Since the third connecting port 214 is blocked by the blocking member 230, at this time, the liquid in the inner drum 50 and the outer drum 40 can only be pumped into the circulation pipeline 90 through the drainage pump 70 to prevent the liquid in the inner drum 50 and the outer drum 40 from entering the third connecting port 214 and affecting the internal circulation spraying effect and the cleaning effect of the clothing processing device 10.

[0198] See also Figure 5 As shown, when the laundry processing device 10 is draining water externally, the blocking member 230 can be located between the first communication port 212 and the second communication port 213 , and the blocking member 230 abuts against the inner wall of the mounting seat 210 to connect the first communication port 212 with the third communication port 214 .

[0199] In this way, when the clothing processing device 10 is draining water externally, the first connecting port 212 is connected to the third connecting port 214. Since the second connecting port 213 is blocked by the blocking member 230, at this time, the liquid in the inner drum 50 and the outer drum 40 can only be pumped into the drain pipe 80 through the drainage pump 70 to prevent the liquid in the inner drum 50 and the outer drum 40 from entering the second connecting port 213 and affecting the external drainage effect of the clothing processing device 10.

[0200] Furthermore, since the blocking member 230 has moved between the first communication port 212 and the second communication port 213, the third communication port 214 is in an open state. At this time, the first communication port 212 can be connected to the third communication port 214, which can ensure the external drainage function of the clothing processing device 10. At the same time, it can be ensured that the first communication port 212 and the third communication port 214 are not blocked by the blocking member 230 and are in a completely open state. In this way, when the liquid flows from the first communication port 212 to the third communication port 214, the lint in the liquid is not easy to block the first communication port 212 and the third communication port 214, so as to ensure that the liquid of the drainage pump 70 can be smoothly discharged to the outside of the housing 20 through the drainage pipe 80, thereby enhancing the practicality of the connecting device 200 in the clothing processing device 10.

[0201] At present, most of the clothes processing devices 10 (drum washing machines) adopt upper drainage, which will cause the clothes processing device 10 to be unable to drain the liquid in the drain pipe 80. The liquid will remain in the drain pipe 80, and the residual amount is large. The liquid remaining in the drain pipe 80 (referred to as residual water) will flow back to the outer drum 40 or even the inner drum 50 through the drain pipe 80. When the refluxed residual water remains in the outer drum 40 for a long time, it will cause odor in the clothes processing device 10, and will contaminate the liquid in the inner drum 50 during the next clothes processing program, affecting the washing effect of the clothes processing device 10.

[0202] It should be noted that the upper drainage of the clothes processing apparatus 10 means that the drainage end of the drainage pipe 80 is located on the side of the shell 20 facing the top, so that the drainage pipe 80 drains water from one side of the top of the shell 20.

[0203] Figure 6 Indicated Figure 3 Enlarged view at a3. For this, see Figure 6 As shown, when the laundry processing device 10 performs a laundry processing program or the laundry processing program ends, the blocking member 230 is located at the third communication port 214, and the blocking member 230 can block the third communication port 214 to connect the first communication port 212 with the second communication port 213. After the laundry processing program of the laundry processing device 10 ends, since the third communication port 214 is blocked by the blocking member 230, the reflux channel of the residual water in the drain pipe 80 can be blocked by the blocking member 230, so as to avoid the residual water from refluxing into the outer drum 40 or even the inner drum 50, resulting in odor in the laundry processing device 10, thereby ensuring the washing effect of the laundry processing device 10.

[0204] See also Figures 4 to 6As shown, in some embodiments, the laundry processing apparatus 10 may further include a one-way valve 400. The one-way valve 400 may be provided at the water inlet end of the drain pump 70 or the drain outlet of the outer tub 40, and is configured to connect the drain outlet of the outer tub 40 with the water inlet end of the drain pump 70 under the pressure of the liquid in the outer tub 40.

[0205] When the clothing processing device 10 performs the circulating spray function or external drainage, the one-way valve 400 opens under the pressure of the liquid in the outer drum 40. At this time, the drainage port of the outer drum 40 is connected to the water inlet end of the drainage pump 70, thereby ensuring that the internal circulating spray function or external drainage function of the clothing processing device 10 is realized.

[0206] See also Figure 6 As shown, if the sealing property of the sealing member 230 on the third connecting port 214 is reduced after the clothing processing device 10 has been used for a long time, causing the liquid in the drain pipe 80 to flow back toward the side of the outer drum 40 and pass through the one-way valve 400, since the one-way valve 400 can only conduct in one direction, at this time, the one-way valve 400 is in a closed state and cannot be opened, and the residual water that flows back can be further blocked outside the outer drum 40, thereby achieving secondary blocking of the residual water.

[0207] Therefore, the present application can achieve double blocking of residual water through the blocking piece 230 and the one-way valve 400, so as to further prevent the residual water from flowing back into the outer drum 40 or even the inner drum 50, causing odor in the clothing processing device 10, thereby ensuring the cleaning effect of the clothing processing device 10.

[0208] See also Figure 6 As shown, in some embodiments, the one-way valve 400 can be a rubber one-way valve, and one end of the rubber one-way valve can be a circular ring-shaped opening structure, which is in a normally open state. The other end of the rubber one-way valve can be in a flat closed state, that is, the inner walls on both sides of the one-way valve 400 are attached to each other. During installation, one end of the circular ring opening can face the direction of the outer cylinder 40, and the closed end can face one end of the drainage pump 70.

[0209] See also Figure 5 As shown, during use, the liquid in the outer tube 40 can enter the one-way valve 400 from the open end. Since the rubber material is relatively soft, the closed end of the one-way valve 400 will be opened under the pressure of the liquid and the suction of the drainage pump 70, so that the closed end is in an open state, so that the mixed liquid in the outer tube 40 can enter the drainage pump 70.

[0210] See also Figure 6 As shown, when the drainage is completed, the mixed liquid in the outer cylinder 40 is drained, and the end of the one-way valve 400 facing the drainage pump 70 will return to a closed state, thereby preventing the water outside the outer cylinder 40 from flowing back into the outer cylinder 40 through the one-way valve 400, thereby playing an effective role in blocking residual water.

[0211] The structure of the communication device 200 of the present application and its cooperation with the control device 300 are further described below in conjunction with the drawings and specific embodiments.

[0212] Figure 6 The structure of the first communication device 200 provided in the embodiment of the present application is shown in FIG. Referring to the accompanying drawings, the structure of the first communication device 200 and its cooperation with the control device 300 are further described below.

[0213] See also Figure 6 As shown, in the first connecting device 200, the moving part 220 can be constructed to be able to move relative to the control device 300 along the first direction under the traction force of the control part 310, so that the blocking part 230 can be driven by the moving part 220 to move simultaneously along the first direction, so that the blocking part 230 can be located at the third connecting port 214, or between the first connecting port 212 and the second connecting port 213, so as to selectively connect the first connecting port 212 with the second connecting port 213 or the third connecting port 214.

[0214] Figure 7 The schematic diagram shows the connection between the first communication device 200 and the control device 300 in the first state. Figure 8 The schematic diagram shows the connection between the first communication device 200 and the control device 300 in the second state.

[0215] Among them, for the connecting device 200, the first state is a state in which the first connecting port 212 and the second connecting port 213 of the connecting device 200 are connected, and the third connecting port 214 is blocked. At this time, the clothing processing device 10 can realize the internal circulation spray function.

[0216] For the connecting device 200, the second state is a state in which the first connecting port 212 and the third connecting port 214 of the connecting device 200 are connected, and the blocking member 230 blocks the first connecting port 212 and the second connecting port 213. At this time, the clothing processing device 10 can realize the external drainage function.

[0217] See also Figure 7 and Figure 8As shown, one end of the blocking member 230 adjacent to the third communication port 214 is a blocking end 231, and along the first direction, the blocking end 231 is opposite to the third communication port 214. When the moving member 220 moves relative to the control device 300 along the first direction under the traction of the control member 310, it can drive the blocking end 231 to move simultaneously along the first direction in the communication cavity 211, so as to connect the first communication port 212 with the second communication port 213 or the third communication port 214, thereby selectively connecting the first communication port 212 with the second communication port 213 or the third communication port 214, and realizing the internal circulation spraying function or the external drainage function of the clothing processing device 10.

[0218] like Figure 7 As shown, when the blocking end 231 moves along the first direction to the third connecting port 214, the blocking end 231 can block the third connecting port 214 to connect the first connecting port 212 with the second connecting port 213, so that the drainage pump 70 can pump the liquid in the inner drum 50 and the outer drum 40 into the circulation pipeline 90, thereby realizing the internal circulation spraying function of the clothing processing device 10.

[0219] like Figure 8 As shown, when the blocking end 231 moves along the first direction to between the first connecting port 212 and the second connecting port 213, the blocking end 231 abuts against the inner wall of the mounting seat 210 to connect the first connecting port 212 with the third connecting port 214, so that the drain pump 70 can pump the liquid in the inner drum 50 and the outer drum 40 into the drain pipe 80, thereby realizing the external drainage function of the clothing processing device 10.

[0220] Fig. 9 Shows Figure 7 The enlarged view at b1, Fig.10 Shows Figure 7 Enlarged view at b1.

[0221] See also Fig. 9 and Fig.10 As shown, in some embodiments, the blocking member 230 may have a first blocking portion 2311 and a second blocking portion 2312 at the blocking end 231. The first blocking portion 2311 may be located in the circumference of the blocking end 231, and the second blocking portion 2312 may be located on the end surface of the blocking end 231.

[0222] like Fig. 9As shown, when the blocking end 231 moves along the first direction to the third connecting port 214, the first blocking portion 2311 and the second blocking portion 2312 are both located on the peripheral side of the third connecting port 214 and abut against the inner wall of the mounting seat 210 at the same time, so as to realize double blocking of the third connecting port 214 by the blocking end through the first blocking portion 2311 and the second blocking portion 2312, thereby enhancing the blocking effect of the blocking end on the third connecting port 214 to prevent residual water from flowing back into the outer drum 40, and at the same time, ensure the internal circulation spraying effect of the clothing processing device 10.

[0223] For example, the first blocking portion 2311 may abut against the inner wall of the end of the mounting seat 210 at the end where the third connecting port 214 is provided, and the second blocking portion 2312 may abut against the circumferential inner wall of the mounting seat 210 and be adjacent to the third connecting port 214. The inner wall of the mounting seat 210 includes not only the inner wall of the end but also the circumferential inner wall.

[0224] like Fig.10 As shown, when the sealing end 231 moves along the first direction to between the first connecting port 212 and the second connecting port 213, the first sealing portion 2311 can abut against the circumferential inner wall of the mounting seat 210, so that the first sealing portion 2311 can block between the first connecting port 212 and the second connecting port 213 to avoid the first connecting port 212 and the second connecting port 213 from being connected. At the same time, it can ensure that the first connecting port 212 and the third connecting port 214 are not blocked by the sealing member 230 and are in a completely open state, so that the wire scraps in the liquid are not easy to block the first connecting port 212 and the third connecting port 214, so as to ensure that the liquid of the drain pump 70 can be smoothly discharged to the outside of the shell 20 through the drain pipe 80.

[0225] It should be noted that when the first blocking portion 2311 blocks the first communication port 212 and the second communication port 213, the first blocking portion 2311 may include but is not limited to abutting against a side of the circumferential inner wall of the mounting seat 210 adjacent to the first communication port 212 (such as Fig. 9 For example, the first blocking portion 2311 may also abut against a side of the circumferential inner wall of the mounting seat 210 adjacent to the second communication port 213 .

[0226] See also Fig.10 As shown, in some embodiments, the first sealing portion 2311 and the second sealing portion 2312 can both be annular structures, so that in the circumferential direction of the sealing end portion 231, the first sealing portion 2311 and the second sealing portion 2312 can abut against the inner wall of the mounting seat 210, thereby enhancing the sealing effect of the first sealing portion 2311 and the second sealing portion on the third connecting port 214, and enhancing the blocking effect of the first sealing portion 2311 between the first connecting port 212 and the second connecting port 213.

[0227] There may be at least one first blocking portion 2311. For example, in some embodiments, there may be one first blocking portion 2311, and in other embodiments, there may be more than two first blocking portions 2311. When there may be more than two first blocking portions 2311, the two or more first blocking portions 2311 may be arranged at intervals along the first direction in the circumference of the blocking end portion 231 to enhance the blocking effect of the first blocking portion 2311 on the third communication port 214 and the blocking effect of the first communication port 212 and the second communication port 213.

[0228] like Fig. 9 As shown, in some embodiments, the blocking end portion 231 may further have a third blocking portion 2313 on the end surface. The shape of the third blocking portion 2313 matches the shape of the third communication port 214. When the blocking end portion 231 moves to the third communication port 214 along the first direction, at least part of the third blocking portion 2313 is located inside the third communication port 214 to block the third communication port 214. On the basis of the first blocking portion 2311 and the second blocking portion 2312, the third blocking portion 2313 can be provided to block the inside of the third communication port 214, so as to further enhance the blocking effect of the blocking end portion 231 on the third communication port 214.

[0229] It should be noted that, the “shape of A matches the shape of B” mentioned in the present application can be understood as the shape of A being the same as or similar to the shape of B. For example, “the shape of the third blocking portion 2313 matches the shape of the third communication port 214” can be understood as the shape of the third blocking portion 2313 being the same as or similar to the shape of the third communication port 214. If there are similar descriptions below, this understanding can be made.

[0230] See also Figure 7 As shown, along the first direction (X direction), the blocking member 230 has a middle section 233 on the side of the blocking end 231 facing the control device 300. In some embodiments, the outer diameter of the middle section 233 may be smaller than the outer diameter of the blocking end 231. In this way, while ensuring the blocking effect of the blocking end 231 on the third communication port 214, the blocking member 230 may be in a retracted structure at the position of the middle section 233 along the first direction.

[0231] By setting the plugging member 230 to be retracted in the middle section 233, when ensuring the first communication port 212 and the second communication port 213 are connected, the blocking of the first communication port 212 by the plugging member 230 can be further reduced, so that the first communication port 212 is as completely open as possible. In this way, when the liquid flows from the first communication port 212 to the second communication port 213, the wire scraps in the liquid are not easy to block the first communication port 212 and the second communication port 213, so as to ensure that the liquid of the drainage pump 70 can be smoothly circulated to the inner cylinder 50 through the circulation pipeline 90.

[0232] In some embodiments, the blocking end 231 can be a flexible structure with a cavity, and the end of the moving part 220 can be inserted into the cavity of the blocking end 231, so that the blocking end 231 can be inserted into the blocking end 231 to drive the blocking end 231 to move and selectively connect the first connecting port 212 with the second connecting port 213 and the second connecting port 213.

[0233] At the same time, the blocking end 231 can be deformed by setting the flexible structure of the blocking end 231. In this way, when the blocking end 231 moves in the mounting seat 210, when the first blocking portion 2311 and the second blocking portion 2312 abut against the inner wall of the mounting seat 210, the first blocking portion 2311 and the second blocking portion 2312 can both be deformed when in contact with the inner wall of the mounting seat 210, so that the first blocking portion 2311 and the second blocking portion 2312 are interference-fitted with the inner wall of the mounting seat 210, so as to achieve the abutment of the first blocking portion 2311 and the second blocking portion 2312 against the inner wall of the mounting seat 210.

[0234] At the same time, since both the first blocking portion 2311 and the second blocking portion 2312 can be deformed, it is also possible to facilitate the blocking member 230 to move toward one side of the control device 300 driven by the moving member 220. In addition, when the third blocking portion 2313 is located in the third communication port 214, it can also be interference fit with the mounting seat 210 at the third communication port 214, so that the third blocking portion 2313 abuts against the inner wall of the mounting seat 210, thereby enhancing the blocking effect of the third blocking portion 2313 on the third communication port 214.

[0235] In some embodiments, the blocking end portion 231 may also adopt a flexible structure only at the first blocking portion 2311 , the second blocking portion 2312 , and the third blocking portion 2313 , and adopt a non-flexible structure at other locations.

[0236] The following uses the blocking end portion 231 as an example of a flexible structure to further illustrate the structure of the first communication device 200 .

[0237] See also Fig.10As shown, in some embodiments, the end of the moving part 220 may also have a supporting portion 221. The shape of the supporting portion 221 matches the shape of the cavity of the blocking end 231. The supporting portion 221 is supported on the inner side of the cavity of the blocking end 231 to ensure the stability of the structure and shape of the blocking end 231, which can prevent the blocking effect of the blocking end 231 from failing after the clothing processing device 10 has been used for a long time. At the same time, it can also prevent any one of the first blocking portion 2311, the second blocking portion 2312 and the third blocking portion 2313 from being deformed too much into the cavity when it abuts against the inner wall of the mounting seat 210, thereby affecting the blocking effect of the blocking end 231 on the third connecting port 214, and the blocking effect on the first connecting port 212 and the second connecting port 213.

[0238] See also Fig.10 As shown, in some embodiments, the communication device 200 may further include an end cap 250. The end cap 250 is disposed at one end of the mounting base 210 away from the third communication port 214 to seal the communication cavity 211, so that the liquid pumped into the communication cavity 211 by the drainage pump 70 can accurately flow to the second communication port 213 or the third communication port 214, so as to ensure the smooth operation of the internal circulation spraying and external drainage functions of the clothing processing device 10.

[0239] In some embodiments, the end cap 250 may be integrally connected to the control device 300 .

[0240] See also Fig.10 As shown, the moving member 220 can be inserted into the end cover 250 and connected to the control member 310 so that the movement of the moving member 220 can be controlled by the control member 310 .

[0241] See also Fig.10 As shown, one end of the blocking member 230 adjacent to the end cap 250 is a fixed end 232. The fixed end 232 can be installed on a side of the end cap 250 facing the communication cavity 211, so that the blocking member 230 can be installed in the communication cavity 211 through the end cap 250.

[0242] For example, in some embodiments, the side of the end cover 250 facing the connecting cavity 211 may have a support platform, the support platform may be supported in the fixed end 232, and the end of the mounting seat 210 adjacent to the control device 300 may be pressed on the fixed end 232 and installed in the end cover 250 to achieve the installation of the fixed end 232 on the end cover 250.

[0243] See also Fig.10As shown, in some embodiments, the communication device 200 may further include an elastic member 240. The elastic member 240 may be sleeved on the moving member 220 and located between the moving member 220 and the blocking member 230. One end of the elastic member 240 may abut against the moving member 220, and the other end may abut against a side of the end cap 250 facing the communication cavity 211. In other words, the elastic member 240 abuts between the moving member 220 and the end cap 250 to achieve the installation of the elastic member 240 in the communication cavity 211.

[0244] Since the elastic member 240 abuts between the moving member 220 and the end cover 250, when the moving member 220 moves toward the control member 310 under the traction force of the control member 310 and drives the blocking end 231 to move along the first direction from the third connecting port 214 to between the first connecting port 212 and the second connecting port 213, the elastic member 240 is compressed.

[0245] When the blocking end 231 moves along the first direction to between the first connecting port 212 and the second connecting port 213, and the control member 310 releases the moving member 220, the elastic member 240 releases its elastic potential energy and stretches, and is able to exert a rebound force on the moving member 220, so that the moving member 220 moves toward one side of the third connecting port 214 under the action of the rebound force, and drives the blocking end 231 to move to the third connecting port 214 at the same time, so that the moving member 220 and the blocking end 231 are automatically reset.

[0246] See also Figure 8 As shown, in some embodiments, the fixed end 232 can be a telescopic structure that can be telescoped along the first direction. For example, the fixed end 232 can be a bellows or other hollow structures that can be telescoped. In this way, when the elastic member 240 is telescoped, the fixed end 232 can also be telescoped synchronously to ensure that the blocking end 231 can move along the first direction toward or away from the third communication port 214 under the drive of the moving member 220.

[0247] See also Figure 8 As shown, when the laundry processing device 10 adopts the first communication device 200, the control device 300 can be a tractor. The control member 310 can be a traction rope. For example, the traction rope can be a steel wire rope, so as to pull the control member 310 through the steel wire rope, thereby controlling the movement of the control member 310.

[0248] When the clothes processing device 10 is draining water, the traction device can pull the traction rope to move toward the control device 300 through the pulling motion of the traction rope, thereby driving the blocking end 231 to move toward the control device 300, so that the blocking end 231 can move between the first communication port 212 and the third communication port 214 to block the first communication port 212 and the third communication port 214, and at the same time, connect the first communication port 212 and the third communication port 214. At this time, the fixed end 232 and the elastic member 240 are compressed.

[0249] After the external drainage is completed, the traction device can loosen the traction rope to make the traction rope in a relaxed state. At this time, the traction rope no longer has a traction force on the moving part 220. The moving part 220 will move toward one side of the third communication port 214 under the action of the rebound force, and drive the blocking end 231 to move to the third communication port 214 at the same time, so that the moving part 220 and the blocking end 231 are automatically reset. At this time, the blocking end 231 blocks the third communication port 214, which can prevent the residual water in the drainage pipe 80 from flowing back.

[0250] The specific structure of the tractor can be based on the tractor in the prior art, and this application does not limit it.

[0251] Fig.11 The schematic diagram shows a partial structure of another laundry processing device 10 in an internal circulation state. Fig.12 Shows Fig.11 A schematic diagram of a partial structure of the clothes processing device 10 in the external drainage state, Fig.13 Shows Fig.11 The structural diagram of the clothes processing device 10 after the external drainage is completed. It should be noted that, Figures 11 to 13 The clothing processing device 10 shown in the figure is a sample of the second communication device 200 provided in the embodiment of the present application.

[0252] See also Figures 11 to 13 As shown, in another clothing processing device 10 provided in an embodiment of the present application, the control part 310 of the control device 300 can also control the movement of the moving part 220 in the second connecting device 200 to drive the blocking part 230 to move, and selectively connect the first connecting port 212 with the second connecting port 213 and the third connecting port 214, so as to realize the circulating spray function or external drainage function of the clothing processing device 10.

[0253] The difference from the first connecting device 200 is that the moving part 220 is constructed to be able to rotate around the control part 310 and move relative to the control device 300 in a first direction when the control part 310 rotates, so as to drive the blocking part 230 to rotate and move at the same time, so that the first connecting port 212 can be selectively connected with the second connecting port 213 and the third connecting port 214 through the movement of the blocking part 230.

[0254] The structure of the second communication device 200 and its cooperation with the control device 300 are further described below in conjunction with the drawings and embodiments.

[0255] Fig.14 The diagram shows the connection between the second communication device 200 and the control device 300 in the first state. Fig.15 and Fig.16 Schematic diagrams of connection between the second communication device 200 and the control device 300 in the second state are illustrated at different viewing angles.

[0256] See also Figures 14 to 16 As shown, in some embodiments, the moving member 220 can be sleeved on the outside of the control member 310 and threadedly connected to the control member 310. In this way, when the control member 310 rotates, the moving member 220 will rotate around the control member 310, and the moving member 220 can also make a linear motion along the axial direction of the control member 310 during the rotation process, thereby driving the blocking member 230 to rotate and move at the same time, so that the first communication port 212 is selectively connected with the second communication port 213 and the third communication port 214 through the movement of the blocking member 230. In addition, by changing the rotation direction of the control member 310, the automatic reset of the moving member 220 and the blocking member 230 can be achieved, and there is no need to set the elastic member 240.

[0257] The axial direction of the control member 310 is parallel to the first direction (X direction) to ensure that the moving member 220 can move toward or away from the third communication port 214 along the first direction during the rotation process.

[0258] See also Fig.15 As shown, the end of the control member 310 facing the third communication port 214 can be called the end of the control member 310. A toothed external thread structure is provided at the end of the control member 310. An internal thread structure adapted to the control member 310 can be provided on the inner wall of the moving member 220. When the moving member 220 is sleeved on the end of the control member 310, the moving member 220 is threadedly connected to the control member 310.

[0259] The control device 300 may be a motor, and the control component 310 may be a rotating shaft of the motor.

[0260] When the clothing processing device 10 is draining water externally, when the motor is started, the shaft rotates in a first preset direction, so that the moving part 220 can move along the axis of the shaft toward the side away from the third connecting port 214 during the rotation around the shaft, and move to between the first connecting port 212 and the third connecting port 214 to block the first connecting port 212 and the third connecting port 214, and at the same time, connect the first connecting port 212 and the third connecting port 214.

[0261] After the external drainage is completed, the motor controls the shaft to rotate in the second preset direction, so that the moving part 220 can move along the axis of the shaft toward the third communication port 214 during the rotation of the shaft, and move to the third communication port 214 to block the third communication port 214, thereby preventing the drainage pipe 80 from leaking.

[0262] The first preset direction and the second preset direction are two directions opposite to each other.

[0263] Fig.17 yes Fig.14 The enlarged view at b3, Fig.18 yes Fig.15 Enlarged view at b4.

[0264] See also Fig.17 and Fig.18 As shown, the blocking member 230 may also have a first blocking portion 2311 , and the first blocking portion 2311 is located in the circumferential direction of the blocking member 230 .

[0265] The blocking member 230 may also have a first blocking portion 2311 and a second blocking portion 2312 (not shown). The second blocking portion 2312 is located at the end surface of the blocking member 230 .

[0266] When the blocking member 230 moves along the first direction to the third connecting port 214, at least one of the first blocking portion 2311 and the second blocking portion 2312 can abut against the inner wall of the mounting seat 210 on the peripheral side of the third connecting port 214 to block the third connecting port 214 and at the same time connect the first connecting port 212 and the second connecting port 213.

[0267] When the blocking member 230 moves along the first direction to between the first connecting port 212 and the second connecting port 213 , the first blocking portion 2311 can abut against the circumferential inner wall of the mounting seat 210 to block between the first connecting port 212 and the second connecting port 213 , while connecting the first connecting port 212 and the third connecting port 214 .

[0268] The control device 300 can be sealed and connected to one end of the mounting seat 210 away from the third connecting port 214 to ensure the sealing of the connecting cavity 211 on the side adjacent to the control device 300, so that the liquid pumped into the connecting cavity 211 by the drainage pump 70 can accurately flow to the second connecting port 213 or the third connecting port 214 to ensure the smooth operation of the internal circulation spraying and external drainage functions of the clothing processing device 10.

[0269] On the basis of the above, the embodiment of the present application also provides another clothing processing device. A third connecting device is provided in another clothing processing device. The third connecting device also includes a mounting seat and a blocking member. In another clothing processing device, the three connecting ports of the mounting seat are respectively connected to the drainage pump, the drainage pipe and the shower head. When the clothes need to be drained after washing, the control device can drive the blocking member in the connecting device to rotate, and connect the first connecting port with the third connecting port, so that the water outlet of the drainage pump is connected to the water inlet of the drainage pipe. The mixed liquid in the outer drum and the inner drum is pumped into the drainage pipe through the third connecting port, so that the mixed liquid is discharged from the drainage pipe to the outside of the shell. After the drainage is completed, the control device can drive the blocking member to rotate again, so that the first connecting port in the connecting device is connected to the second connecting port, so as to block the connection between the third connecting port and the first connecting port. In this way, when there is residual water in the drain pipe, the residual water can be blocked and intercepted by the connecting device to prevent the residual water in the drain pipe from flowing back into the outer drum and the inner drum, effectively reducing or preventing the residual water from flowing back into the inner drum and the outer drum and causing the outer drum and the inner drum to produce odor, which helps to improve the cleanliness of the outer drum and the inner drum, thereby effectively improving the clothing washing effect.

[0270] The structure of the clothes processing device 10 with the third communication device will be further described below in conjunction with the drawings and embodiments.

[0271] See also Fig.19 As shown, the clothing treatment apparatus 10 may further include a connecting device 200 , wherein the spray head 120 and the drain pipe 80 may be connected to the drain pump 70 via the connecting device 200 , so that water discharged from the drain pump 70 may reach the drain pipe 80 or the spray head 120 via the connecting device 200 .

[0272] For details, see Fig. 20 As shown, the connecting device 200 may include a mounting seat 210 and a blocking member 230. The mounting seat 210 may have a connecting cavity 211 and a first connecting port 212, a second connecting port 213 and a third connecting port 214 connected to the connecting cavity 211. The sprinkler head 120 and the drain pipe 80 may be connected to the drain pump 70 through the mounting seat 210.

[0273] The connecting cavity 211 may be a cylindrical structure, and the central part of the connecting cavity 211 has a rotating shaft, which can be understood as the extension direction of the rotating shaft being consistent with the central axis of the cylindrical connecting cavity 211. The blocking member 230 may be located in the connecting cavity 211, and the blocking member 230 may be rotatably connected to the rotating shaft, for example, the blocking member 230 may rotate around the rotating shaft.

[0274] The first communication port 212, the second communication port 213 and the third communication port 214 may be distributed along the circumference of the communication cavity 211, wherein the first communication port 212 may be connected to the water outlet of the drainage pump 70, and the second communication port 213 may be connected to the sprinkler head 120, for example, the second communication port 213 may be connected to the sprinkler head 120 through the circulation pipeline 90. The third communication port 214 may be connected to the water inlet end of the drainage pipe 80. For example, the first communication port 212 may be connected to the first communication pipe 215, and the first communication port 212 may be connected to the drainage pump 70 through the first communication pipe 215. The second communication port 213 may be connected to the second communication pipe 216, and the second communication port 213 may be connected to the circulation pipeline 90 through the second communication pipe 216. The third communication port 214 may be connected to the third communication pipe 217, and the third communication port 214 may be connected to the drainage pipe 80 through the third communication pipe 217.

[0275] The clothing processing device 10 may further include a control device 300 , which may be connected to the blocking member 230 , and may be used to drive the blocking member 230 to rotate around the rotating axis in the connecting cavity 211 to connect the first connecting port 212 with the second connecting port 213 or the third connecting port 214 .

[0276] See also Fig. 20 As shown, during the washing process of the clothes, the control device 300 can drive the blocking member 230 to rotate, connect the first connecting port 212 with the second connecting port 213, so that the water outlet of the drain pump 70 is connected with the water inlet of the circulation pipeline 90. At this time, the drain pump 70 is started, and the drain pump 70 can extract the mixed liquid in the outer drum 40 and the inner drum 50 from the drain port at the bottom of the outer drum 40, and pump it into the circulation pipeline 90 through the second connecting port 213, so as to be transported to the spray head 120 through the circulation pipeline 90. So that the mixed liquid is sprayed from the spray head 120 at the top of the outer drum 40 to the clothes, so that the clothes are repeatedly rinsed, which can effectively improve the washing effect of the clothes. The clothes processing device 10 can effectively wash the clothes in a short time, which helps to shorten the washing time of the clothes and improve the washing efficiency of the clothes processing device 10.

[0278] See also Fig.21 and Fig. 22As shown, when the clothes need to be drained after washing, the control device 300 can drive the blocking member 230 to rotate, connect the first communication port 212 with the third communication port 214, so that the water outlet of the drainage pump 70 is connected with the water inlet of the drainage pipe 80. At this time, the drainage pump 70 is started, and the drainage pump 70 can draw the mixed liquid in the outer drum 40 and the inner drum 50 from the drainage port at the bottom of the outer drum 40, and pump it into the drainage pipe 80 through the third communication port 214, so that the mixed liquid is discharged from the drainage pipe 80 to the outside of the housing 20.

[0279] Fig.23 A schematic diagram of the structure of a clothes processing device with a third connecting device provided in an embodiment of the present application during drainage. Fig.24 for Fig.23 Magnified view of area C in the middle.

[0280] See also Fig.23 and Fig.24 As shown, after the drainage is completed, the control device 300 can drive the blocking member 230 to rotate again, so that the first communication port 212 in the communication device 200 is connected with the second communication port 213, so as to block the communication between the third communication port 214 and the first communication port 212. In this way, when there is residual water in the drain pipe 80, the residual water can be blocked and intercepted by the communication device 200 to prevent the residual water in the drain pipe 80 from flowing back into the outer drum 40 and the inner drum 50, effectively reducing or preventing the residual water from flowing back into the inner drum 50 and the outer drum 40 and causing the outer drum 40 and the inner drum 50 to produce odor, which helps to improve the cleanliness of the outer drum 40 and the inner drum 50, thereby effectively improving the laundry washing effect.

[0281] Continue to see Fig. 22 As shown, when the blocking member 230 rotates to the second communication port 213, the blocking member 230 can block the second communication port 213, so that the first communication port 212 can communicate with the third communication port 214 through the communication cavity 211. For example, when drainage is required, the control device 300 can drive the blocking member 230 to rotate around the rotation axis, so that the blocking member 230 rotates to the second communication port 213. The blocking member 230 can block the second communication port 213, so that the second communication port 213 is blocked from the communication cavity 211. At this time, the third communication port 214 is in an open state, and the third communication port 214 can communicate with the first communication port 212 through the communication cavity 211.

[0282] The water outlet end of the drain pump 70 can be connected to the water inlet end of the drain pipe 80 through the mounting seat 210 of the connecting device 200, so that the drain pump 70 can pump the mixed liquid in the outer cylinder 40 and the inner cylinder 50 into the drain pipe 80, and discharge it to the outside of the shell 20 through the drain pipe 80.

[0283] Among them, during the drainage process, the sealing member 230 will seal the second connecting port 213 connected to the circulation pipeline 90, which can prevent the mixed liquid from entering the circulation pipeline 90 during the drainage process, and then entering the outer cylinder 40 and the inner cylinder 50 through the circulation pipeline 90 and the sprinkler head 120 to form residual water, which can make the drainage more thorough, help improve the drainage effect, and reduce the residual water retained in the cylinder.

[0284] See also Fig.24 As shown, when the blocking member 230 rotates to the third communication port 214, the blocking member 230 can block the third communication port 214, so that the first communication port 212 can communicate with the second communication port 213 through the communication cavity 211. For example, when drainage is required, the control device 300 can drive the blocking member 230 to rotate around the rotation axis, so that the blocking member 230 rotates to the second communication port 213. The blocking member 230 can block the second communication port 213, so that the second communication port 213 is blocked from the communication cavity 211. At this time, the third communication port 214 is in an open state, and the third communication port 214 can communicate with the first communication port 212 through the communication cavity 211.

[0285] The water outlet end of the drainage pump 70 can be connected to the water inlet end of the circulation pipeline 90 through the connecting device 200, so that the drainage pump 70 can pump the mixed liquid in the outer drum 40 and the inner drum 50 into the circulation pipeline 90, so that the mixed liquid can reach the spray head 120 through the circulation pipeline 90 to circulate and spray the clothes.

[0286] Among them, during the circulation spraying process, the sealing member 230 will seal the third connecting port 214 connected to the drain pipe 80, which can prevent the residual water in the drain pipe 80 from entering the circulation pipeline 90 during the clothing washing process, and then entering the outer drum 40 and the inner drum 50 through the circulation pipeline 90 and the spray head 120, which can improve the effective residual water blocking effect and prevent the residual water in the drain pipe 80 from entering the outer drum 40 and the inner drum 50 and causing pollution.

[0287] Continue to see Fig.24 As shown, the laundry processing device 10 may further include a one-way valve 400, and the water inlet end of the drain pump 70 is connected to the drain outlet of the outer tub 40. Fig.24 As shown, the one-way valve 400 can be provided at the water inlet end of the drain pump 70 or the drain outlet of the outer cylinder 40. The one-way valve 400 is configured to unidirectionally communicate the drain outlet of the outer cylinder 40 with the water inlet end of the drain pump 70. In other words, the one-way valve 400 can allow the water in the outer cylinder 40 to flow into the drain pump 70 through the one-way valve 400, and prevent the water in the drain pump 70 from flowing back into the outer cylinder 40 through the one-way valve 400.

[0288] See also Fig. 20 and Fig. 22As shown, during the process of circulating spraying and draining, the water in the outer drum 40 can flow to the drain pump 70 through the one-way valve 400, and then flow to the circulation pipeline 90 or the drain pipe 80 through the drain pump 70. Fig.24 As shown, after drainage is completed and the clothing processing device 10 stops working, the one-way valve 400 can block the water path of the drainage pump 70 toward the outer drum 40 to prevent the residual water outside from flowing back into the outer drum 40 from the drainage port at the bottom of the outer drum 40, which can effectively prevent the residual water from flowing into the outer drum 40 and generating odor or pollution, etc., and can effectively play the role of blocking the residual water.

[0289] For example, the one-way valve 400 can be a rubber one-way valve 400, one end of which is a circular ring-shaped opening structure, which is in a normally open state, and the other end is in a flat closed state, that is, the inner walls of the two sides of the one-way valve 400 are attached to each other. During installation, one end of the circular ring opening can be facing the direction of the outer cylinder 40, and the closed end can be facing one end of the drainage pump 70. During use, water in the outer cylinder 40 can enter the one-way valve 400 from the open end. Since the rubber material is relatively soft, the closed end of the one-way valve 400 will be flushed open under the gravity of the water and the suction of the drainage pump 70, so that the closed end is in an open state, so that the mixed liquid in the outer cylinder 40 can enter the drainage pump 70.

[0290] When the drainage is completed, the mixed liquid in the outer cylinder 40 is completely drained, and the end of the one-way valve 400 facing the drainage pump 70 will return to a closed state, thereby preventing the water outside the outer cylinder 40 from flowing back into the outer cylinder 40 through the one-way valve 400, thereby playing an effective role in blocking residual water.

[0291] Fig.25 A schematic diagram of the structure of a third connecting device and a control device in one state provided in an embodiment of the present application.

[0292] See also Fig.25 As shown, the laundry processing device 10 may further include a moving member 220, which may be connected to the blocking member 230, and the moving member 220 may be rotatably connected to the rotating shaft, and the moving member 220 may be connected to the control device 300. The moving member 220 is configured to rotate around the rotating shaft under the traction of the control device 300, so as to drive the blocking member 230 to rotate around the rotating shaft.

[0293] For example, the moving member 220 may be a traction rod, and the control device 300 may drive the moving member 220 to reciprocate around the rotation axis, so that the moving member 220 may drive the blocking member 230 to reciprocate around the rotation axis, so that the blocking member 230 may switch between the position of the second communication port 213 and the position of the third communication port 214. Thus, the blocking member 230 may block the second communication port 213 or the third communication port 214.

[0294] Among them, the blocking member 230 can be a structural member with a relatively soft material. For example, the blocking member 230 can be a rubber member, etc., so that when the blocking member 230 is at the second connecting port 213 or the third connecting port 214, it can effectively seal the second connecting port 213 or the third connecting port 214, and can improve the tightness of the contact between the blocking member 230 and the second connecting port 213 or the third connecting port 214, thereby effectively improving the sealing reliability of the blocking member 230.

[0295] The moving part 220 may be a structural part with certain strength and rigidity. When the control device 300 drives the moving part 220 , the moving part 220 may respond and move in time under the drive of the control device 300 , thereby improving the movement sensitivity of the moving part 220 .

[0296] Fig.26 A schematic diagram of the structure of a third connecting device and a control device in one state provided in an embodiment of the present application.

[0297] Continue to see Fig.25 As shown, the control device 300 may further include a control member 310, which may be connected to the moving member 220, and the control member 310 may be used to control the moving member 220 to rotate around the rotating shaft, so that the moving member 220 drives the blocking member 230 to move between the second communication port 213 and the third communication port 214.

[0298] For example, see Fig.25 As shown, when circulating spraying is required, the control member 310 in the control device 300 can control the moving member 220 to rotate around the rotating shaft, so that the moving member 220 can drive the blocking member 230 to rotate to the third connecting port 214 to block the third connecting port 214, so that the drainage pump 70 can pump the mixed liquid into the circulation pipeline 90 connected to the second connecting port 213. Fig.26 As shown, when drainage is required, the control member 310 in the control device 300 can control the moving member 220 to rotate around the rotating shaft, so that the moving member 220 can drive the blocking member 230 to rotate to the second connecting port 213 to block the second connecting port 213, so that the drainage pump 70 can pump the mixed liquid into the drainage pipe 80 connected to the third connecting port 214, so that the mixed liquid can be discharged from the shell 20 through the drainage pipe 80.

[0299] Continue to see Fig.25 and Fig.26As shown, the clothes processing device 10 may further include an elastic member 240, which may be located in the communication cavity 211, and one end of the elastic member 240 may be connected to the blocking member 230, and the other end may be connected to the mounting seat 210. When the control member 310 drives the blocking member 230 to rotate to the second communication port 213, the elastic member 240 may be in an elastically compressed state, and when the control member 310 releases the blocking member 230, the elastic member 240 may drive the blocking member 230 to rotate to the third communication port 214.

[0300] For example, when the control member 310 applies a driving force to the moving member 220, the control member 310 can drive the moving member 220 to rotate, so that the moving member 220 can drive the blocking member 230 to rotate to the second connecting port 213. At this time, the elastic member 240 can be in an elastically compressed state, and the elastic member 240 in the elastically compressed state can have a rebound force, and the rebound force can drive the blocking member 230 toward the third connecting port 214. When the control member 310 releases the moving member 220, the force of the control member 310 on the moving member 220 is cancelled, and the moving member 220 and the blocking member 230 no longer receive the driving force of the control device 300. At this time, the rebound force of the elastic member 240 can drive the blocking member 230 to rotate toward the position of the third connecting port 214, so that the blocking member 230 is blocked at the third connecting port 214.

[0301] The control device can control the moving part 220 through the control part 310 so that the moving part 220 can drive the blocking part 230 to rotate around the rotating shaft, so that the blocking part 230 can switch between the second connecting port 213 and the third connecting port 214, thereby realizing the switching between the first connecting port 212 and the second connecting port 213 and the third connecting port 214.

[0302] For example, when drainage is required, the control device 300 can apply a driving force to the moving member 220 through the control member 310 to drive the moving member 220 to rotate, so that the moving member 220 can drive the blocking member 230 to rotate to the second connecting port 213 to block the second connecting port 213, thereby preventing the mixed liquid from entering the circulation pipeline 90 during the drainage process. When drainage is completed, the control device 300 cancels the driving force of the control member 310 on the moving member 220. At this time, the blocking member 230 can be restored to the third connecting port 214 under the action of the elastic member 240 to block the third connecting port 214, thereby preventing the residual water in the drainage pipe 80 from flowing back into the outer cylinder 40 and the inner cylinder 50.

[0303] For example, see Fig.25 and Fig.26As shown, the elastic member 240 can be a torsion spring, which can be sleeved on the rotating shaft, and one end of the torsion spring can be connected to the blocking member 230, and the other end can be connected to the mounting seat 210. When the control member 310 drives the blocking member 230 to rotate to the second connecting port 213 through the moving member 220, the torsion spring can be in an elastically compressed state. When the control member 310 cancels the driving force on the moving member 220, the blocking member 230 can be reset to the third connecting port 214 under the action of the rebound force of the torsion spring, so that the blocking member 230 can block the third connecting port 214. The reliability and stability of the resetting of the blocking member can be effectively improved.

[0304] For the third type of connecting device, the control device 300 may be a traction device, and the control member 310 may be a traction rope, for example, the traction rope may be a steel wire rope. During the drainage process, the traction device may pull the traction rope so that the traction rope can pull the moving member 220 to rotate, so that the blocking member 230 blocks the second connecting port 213. When the drainage is finished, the traction device may loosen the traction rope so that the traction rope is in a relaxed state, so that the traction rope no longer applies tension to the moving member 220. At this time, the blocking member 230 may rotate and reset to the third connecting port 214 under the action of the rebound force of the elastic member 240, so as to block the third connecting port 214, thereby preventing the residual water in the drain pipe 80 from flowing back.

[0305] The present application also provides a variety of spray assemblies. The structure of the spray assembly of the present application is further described below in conjunction with several different embodiments.

[0306] Example 1

[0307] In the related art, the spray holes on the spray head are usually circular holes, so that after the liquid in the inner drum 50 and the outer drum 40 is sprayed into the inner drum 50 through the spray holes, the coverage area and pressure in the inner drum 50 are limited, making it difficult to wash clothes efficiently, and the washing effect of the clothing processing equipment needs to be improved.

[0308] See also Fig. 27As shown, the clothing treatment device 10 of the embodiment of the present application may be provided with a liquid inlet pipeline and a spray assembly 100. The spray assembly 100 may have a spray head 120 connected to the water outlet end of the liquid inlet pipeline, and a spray hole 121 is provided on the spray head 120. The present application improves the shape of the spray hole 121 of the spray head 120 so that the pressure of the liquid can be instantly increased when the liquid is sprayed through the spray hole 121, and has a larger spray area, so that the liquid sprayed by the spray head 120 to the inner drum 50 can cover and rinse the clothes in the inner drum 50 over a large area, and can wash the clothes efficiently and improve the washing effect. At the same time, the liquid sprayed by the spray head 120 to the inner drum 50 can also rinse the inner drum 50, the door seal 60, the door body 30, etc., to avoid the impurities such as foam generated by the detergent remaining in the inner drum 50 and the door body 30, so as to ensure the washing effect of the clothes and the health of the user.

[0309] The spraying region of the spraying assembly 100 may include the spraying region of the spraying hole 121. Accordingly, the spraying area of ​​the spraying assembly 100 may include the area occupied by the spraying region of the spraying hole 121.

[0310] The structure of the clothes processing device 10 is further described below in conjunction with the accompanying drawings and embodiments.

[0311] Figures 28 to 30 The schematic diagram shows the structure of the first spray assembly at different viewing angles. Fig.31 yes Fig.30 A schematic structural diagram of the middle shower head 120 at a first viewing angle.

[0312] See also Figures 27 to 30 As shown, the laundry treating apparatus 10 may include the liquid inlet pipeline mentioned above.

[0313] See also Figure 28 to Figure 31 As shown, the clothing treatment device 10 may further include a spray assembly 100. The spray assembly 100 may include a spray head 120. The spray head 120 may be connected to the water outlet end of the liquid inlet pipeline. The liquid in the liquid inlet pipeline is sprayed to the inner drum 50 through the spray head 120, so that the liquid in the liquid inlet pipeline can be sprayed into the inner drum 50 through the spray head 120, thereby washing the clothes in the inner drum 50.

[0314] Fig.32 Shows Fig.28 The cross-section view in the AA direction, Fig.33 Shows Fig.29 Cross-sectional view in the BB direction.

[0315] See also Fig.32 and Fig.33As shown, the spray head 120 may have a spray hole 121 for spraying liquid, so that the liquid in the liquid inlet pipeline can be sprayed into the inner drum 50 through the spray hole 121, thereby washing the clothes in the inner drum 50.

[0316] See also Fig.33 As shown, along the flow direction of the liquid in the spray hole 121:

[0317] The spray hole 121 may have a liquid inlet section 1211 and a liquid outlet section 1212 , wherein the liquid inlet section 1211 may have a contraction structure, and the liquid outlet section 1212 may have an expansion structure.

[0318] In this way, along the flow direction of the liquid in the spray hole 121, the cross-sectional area of ​​the liquid inlet section 1211 gradually decreases, and the cross-sectional area of ​​the liquid outlet section 1212 gradually increases.

[0319] The cross-sectional areas of the spray hole 121 in the liquid inlet section 1211 and the liquid outlet section 1212 can be formed by the same cross section. The cross section is perpendicular to the axial direction of the spray hole 121. The axial direction of the spray hole 121 can be referred to as the Z direction, and the Z direction is used to replace the axial direction of the spray hole 121 in the following description.

[0320] It should be understood that, generally, when a liquid flows in a pipe, the flow rate of the liquid is inversely proportional to the cross-sectional area of ​​the pipe.

[0321] Since the spray hole 121 can also be regarded as a kind of pipe, the cross-sectional area of ​​the liquid inlet section 1211 gradually decreases along the flow direction of the liquid in the spray hole 121. Therefore, when the liquid flows in the liquid inlet section 1211, the flow velocity of the liquid increases continuously in the process of flowing in the liquid inlet section 1211. When the flow velocity of the liquid increases to a critical point in the liquid inlet section 1211, the flow velocity will not increase any more. At the critical point, the velocity of the fluid is greater than the speed of sound.

[0322] When the velocity of the fluid is greater than the speed of sound, the above-mentioned inverse proportionality between the flow velocity and the cross-sectional area of ​​the liquid is no longer applicable, but just the opposite. The larger the cross-sectional area, the faster the flow velocity of the liquid. Since the cross-sectional area of ​​the liquid outlet section 1212 gradually increases along the flow direction of the liquid in the spray hole 121, when the liquid enters the liquid outlet section 1212, the liquid continues to accelerate and becomes supersonic, so that the flow velocity of the liquid can be instantly increased when the liquid is sprayed out through the spray hole 121. For the spray hole 121, the flow velocity is proportional to the pressure. Therefore, when the flow velocity of the liquid increases instantly, the pressure of the liquid also increases instantly, which can effectively rinse the clothes in the inner drum 50 and improve the cleaning effect.

[0323] At the same time, since the cross-sectional area of ​​the liquid outlet section 1212 gradually increases along the flow direction of the liquid in the spray hole 121, the liquid has a larger spraying area when it is sprayed to the inner drum 50 through the liquid outlet section 1212, so that the liquid sprayed to the inner drum 50 through the spray hole 121 can cover a large area and rinse the clothes in the inner drum 50, which can efficiently wash the clothes and improve the cleaning effect.

[0324] In addition, the liquid sprayed by the spray head 120 to the inner drum 50 has a higher pressure and a larger spraying area, and part of the door body 30 usually protrudes toward one side of the inner drum 50, and the door seal 60 is located on the peripheral side of the protruding part of the door body 30. Therefore, the liquid sprayed by the spray head 120 to the inner drum 50 can not only flush the inner drum 50 over a larger area, but also flush the door body 30, the door seal 60, etc. over a larger area, so that the inner drum 50, the door seal 60, the door body 30, etc. are effectively flushed to avoid impurities such as foam generated by detergent from remaining in the inner drum 50, the door seal 60, and the door body 30, thereby improving the cleaning effect and ensuring the health of users.

[0325] In some embodiments, when the liquid inlet pipeline is a circulation pipeline 90, the liquid (such as washing water) in the inner drum 50 and the inner and outer drums 40 can be sprayed into the inner drum 50 through the spray hole 121, effectively washing the clothes in the inner drum 50, so that the clothes can be better soaked, so that the liquid can better disperse the stains attached to the surface of the clothes, thereby improving the cleaning effect. In addition, the liquid can be sprayed on the clothes through the spray head 120, and the liquid can also be hit on the clothes, effectively reducing the entanglement between the clothes, improving the cleaning effect, and at the same time, protecting the quality of the fabric of the clothes.

[0326] It should be noted that when the liquid inlet pipeline is a circulation pipeline 90, on the basis of achieving the same cleaning effect, compared with the clothing processing equipment in the related technology, the clothing processing equipment 10 of the present application has an improved cleaning effect. Therefore, the clothing processing equipment 10 of the present application also has the characteristics of saving time, saving electricity and reducing energy consumption.

[0327] In some embodiments, when the liquid inlet pipeline is a water inlet pipeline, the liquid in the liquid inlet pipeline can be water flowing into the water inlet pipeline from an external water source. The water inlet pipeline includes a water inlet pipe, a water inlet valve and a water inlet pipe branch. The water inlet pipe is connected to an external water source, and the water inlet valve is arranged between the water inlet pipe and the water inlet pipe branch. The water in the water inlet pipe can enter the water inlet pipe branch through the water inlet valve, and the water outlet end of the water inlet pipe branch is connected to the spray assembly 100. The water flowing through the water inlet pipe branch can bring detergent into the inner drum 50, and spray into the inner drum 50 through the spray hole 121, which can also better soak the clothes, thereby improving the washing effect. At the same time, when the water in the water inlet pipeline can be sprayed into the inner drum 50 through the spray hole 121, it can also effectively reduce the entanglement between clothes, improve the washing effect, and protect the quality of the fabric of the clothes.

[0328] It should be noted that the connection between the water inlet pipe, the water inlet valve and the water inlet pipe branch can be determined according to the structure of the clothing processing device 10 in the relevant technology, and will not be repeated in this application.

[0329] The structure of the clothes processing device 10 is further described below by taking the liquid inlet pipeline as the circulation pipeline 90 as an example.

[0330] See again Fig. 27 As shown, in some embodiments, the laundry processing device 10 may further include a connecting device. The connecting device may be a three-way valve or the like. The connecting device is disposed in the housing 20. The connecting device may selectively connect the water outlet of the drain pump 70 to the water inlet of the circulation pipeline 90 and the water inlet of the drain pipe 80.

[0331] When the liquid in the inner drum 50 and the outer drum 40 needs to be circulated and sprayed, the connecting device can connect the water outlet of the drain pump 70 with the water inlet of the circulation pipeline 90 and the water inlet of the drain pipe 80. When the drain pump 70 is started, the drain pump 70 can pump the liquid in the inner drum 50 and the outer drum 40 into the circulation pipeline 90 and directly reach the spray head 120. The liquid sprayed from the spray head 120 can wash the wall of the inner drum 50, the clothes in the inner drum 50, the door body 30, and the door seal 60.

[0332] When it is necessary to drain the liquid in the inner cylinder 50 and the outer cylinder 40 to the outside of the housing 20, the connecting device can connect the water outlet of the drain pump 70 with the water inlet of the drain pipe 80. When the drain pump 70 is started, the drain pump 70 can pump the liquid in the inner cylinder 50 and the outer cylinder 40 into the drain pipe 80, and the liquid can be discharged to the outside of the housing 20 through the drain pipe 80.

[0333] It should be noted that the structure of the communication device can be determined according to the structure of the clothing processing device 10 in the related art, and will not be described in detail in this application.

[0334] During the washing, rinsing and dehydration process of the clothing processing device 10, the liquid in the liquid inlet pipeline can be sprayed out from the spray hole 121 at any time according to the program design of the clothing processing device 10 to flush the wall of the inner drum 50, the clothes in the inner drum 50, the door body 30 and the door seal 60.

[0335] The structure of the first spray assembly is further described below.

[0336] Fig.34 Shows Fig.31 Cross-sectional view along CC direction.

[0337] See also Fig.34 As shown, in some embodiments, along the flow direction of the liquid in the spray hole 121:

[0338] The inner diameter of the liquid inlet section 1211 can gradually decrease, the inner diameter of the liquid outlet section 1212 can gradually increase, and the inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212 at the opposite ends can be equal, so that along the flow direction of the liquid in the spray hole 121, the cross-sectional area of ​​the liquid inlet section 1211 gradually decreases to form a contraction structure, and the cross-sectional area of ​​the liquid outlet section 1212 gradually increases to form an expansion structure.

[0339] Furthermore, since the inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212 at the opposite ends are equal, the inner diameter of the spray hole 121 can smoothly transition between the liquid inlet section 1211 and the liquid outlet section 1212, so as to ensure that the liquid can flow to the liquid outlet section 1212 along the predetermined water flow direction. At the same time, since the inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212 at the opposite ends are equal, a narrow channel is formed between the liquid inlet section 1211 and the liquid outlet section 1212 of the spray hole 121, and when the liquid flows to the narrow channel through the liquid inlet section 1211, the flow rate of the liquid is at the critical point mentioned above.

[0340] See also Fig.34 As shown, when the inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212 at the opposite ends are equal:

[0341] The liquid inlet section 1211 may be directly connected to the liquid outlet section 1212 .

[0342] Alternatively, when the inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212 at the opposite ends are equal:

[0343] The spray hole 121 may also have a connecting section, and the liquid inlet section 1211 and the liquid outlet section 1212 are connected in the connecting section. Along the flow direction of the liquid in the spray hole 121, the inner diameters of the connecting section are equal, and the inner diameter of the connecting section is equal to the minimum inner diameter of the liquid inlet section 1211 and the liquid outlet section 1212, so that the inner diameters of the hole wall of the spray hole 121 at the liquid inlet section 1211 and the liquid outlet section 1212 can smoothly transition with the connecting section to ensure that the liquid can flow to the liquid outlet section 1212 along the established water flow direction.

[0344] Furthermore, by directly connecting the liquid inlet section 1211 and the liquid outlet section 1212 , or by providing a connecting section, the structure of the spray hole 121 can be made more diversified to meet the design requirements of different spray heads 120 for the spray hole 121 .

[0345] Compared with the setting of the connecting section, when the liquid inlet section 1211 is directly connected to the liquid outlet section 1212, the liquid pressure is instantly increased, the spraying area is increased, and the length of the spray hole 121 in the Z direction can be reduced, which is beneficial to reducing the size of the spray head 120 in the Z direction and realizing the miniaturization of the spray head 120.

[0346] Fig.35 and Fig.36 The schematic diagrams are shown respectively Fig.30 Schematic diagram of the structure of the middle shower head 120 at different viewing angles.

[0347] See also Fig.35 and Fig.36 As shown, in some embodiments, the spray head 120 may have a plurality of spray holes 121. The plurality of spray holes 121 may be provided on the side of the spray head 120 facing the inner cylinder 50, so that the liquid in the liquid inlet pipeline is sprayed into the inner cylinder 50 through the spray holes 121. At the same time, by providing the plurality of spray holes 121, the spray area can be further expanded, so as to obtain a better cleaning effect and a flushing effect on the inner cylinder 50, the door seal 60, the door body 30, etc.

[0348] For example, the number of the spray holes 121 may be two, three, four, etc.

[0349] Fig.35 and Fig.36 Four spray holes 121 are shown in FIG. The four spray holes 121 may include but are not limited to being arranged in a "Y" shape on the side of the spray head 120 facing the inner cylinder 50. For example, the four spray holes 121 may also be evenly arranged along the circumference of the spray head 120 on the side of the spray head 120 facing the inner cylinder 50.

[0350] In some embodiments, the spray head 120 may also have one spray hole 121. Compared with multiple spray holes 121, when the size of the spray head 120 is the same, the size of the spray hole 121 can be enlarged, which can also expand the spraying area, and obtain a better cleaning effect and a flushing effect on the inner cylinder 50, the door seal 60, the door body 30, etc.

[0351] See again Fig.29 As shown, in some embodiments, the spray assembly 100 may further include a spray pipe 110. The spray pipe 110 is connected to the water outlet end of the liquid inlet pipeline.

[0352] The spray assembly 100 may further include a fixing member 130. The spray pipe 110 may be connected to the fixing member 130. The spray pipe 110 may be connected to the fixing member 130 by a detachable manner such as a buckle or a thread, or the spray pipe 110 may be integrally connected to the fixing member 130 to form a structural member.

[0353] The fixing member 130 may have a connecting hole 131. The spray head 120 is mounted on the fixing member 130, and the spray head 120 is connected to the spray pipe 110 through the connecting hole 131. In this way, the spray head 120 can be mounted on the water outlet of the liquid inlet pipeline through the fixing member 130 and the spray pipe 110. At the same time, the spray head 120 can also be connected to the water outlet of the liquid inlet pipeline through the connecting hole 131 and the spray pipe 110, so that the liquid in the liquid inlet pipeline can enter the spray head 120 through the spray pipe 110 and the connecting hole 131, and finally spray the liquid to the inner cylinder 50 through the spray hole 121.

[0354] In some embodiments, the spray pipe 110 can be fixed to the outlet end of the liquid inlet pipeline by means of clamping, threading, welding, etc., and communicated with the outlet end of the liquid inlet pipeline. Similarly, the spray pipe 110 can also be connected to the fixing member 130 by means of clamping, threading, welding, etc.

[0355] In some embodiments, when the shower head 120 is mounted on the fixing member 130, the shower head 120 may not rotate relative to the fixing member 130, that is, the shower head 120 always sprays in the same direction. For example, the shower head 120 may be mounted on the fixing member 130 by welding, clamping, etc.

[0356] In some embodiments, when the spray head 120 is mounted on the fixing member 130, the spray head 120 can also rotate relative to the fixing member 130, so as to rotate the spray head 120 to change the spray direction of the spray head 120, further expand the spray area of ​​the spray head 120, so as to obtain a just cleaning effect and a flushing effect on the inner cylinder 50, the door seal 60, the door body 30, etc. For example, the spray head 120 can be mounted on the fixing member 130 by means of a clamping connection, a threaded connection, etc.

[0357] Fig.37 Shows Fig. 27 Enlarged view at D.

[0358] See also Fig.37 As shown, in some embodiments, the spray assembly 100 can be arranged on the door seal 60 and located on the side of the door seal 60 facing the top of the housing 20, so as to realize the installation of the spray assembly 100 in the housing 20. Among them, the spray head 120 can be exposed on the inner side of the door seal 60, so that the liquid can be sprayed into the inner cylinder 50 through the spray hole 121. At the same time, the user can see the spray head 120 from the side facing the door seal 60, so that the water flow sprayed by the spray head 120 has the characteristic of visualization, so that the user can directly see the water flow effect sprayed by the spray head 120.

[0359] It should be noted that the inner side of the door seal 60 can be understood as the side of the door seal 60 facing the tube opening of the outer tube 40 along the radial direction of the outer tube 40 .

[0360] In some embodiments, the spray pipe 110 can be passed through and fixed on the door seal 60, and the water outlet end of the spray pipe 110 can be bent toward the side of the inner cylinder 50 relative to the rest of the spray pipe 110, so that when the spray head 120 is installed on the water outlet end of the spray pipe 110 through the fixing member 130, the spray head 120 can be located on the side of the door seal 60 facing the inner cylinder 50.

[0361] It should be noted that the fixing method of the spray pipe 110 on the door seal 60 can be determined according to the structure of the existing clothing processing device 10, and will not be described in detail in this application.

[0362] In addition to the first type of spray assembly mentioned above, the embodiment of the present application also provides a second type of spray assembly.

[0363] The difference from the first spray assembly is that the second spray assembly has multiple hole groups on the spray head 120, and the multiple hole groups produce different water flow effects during the washing and rinsing process of the clothing processing device 10. The user can rotate the spray head 120 according to the different types of clothes to select a hole group that is suitable for the type of clothes to be connected to the spray pipe 110, thereby producing a water flow effect that is suitable for the type of clothes, and washing, rinsing, etc. the clothes.

[0364] The differences of the second spray assembly are further described below in conjunction with the accompanying drawings.

[0365] Fig.38 and Fig.39 The schematic diagrams of the structure of the second spray assembly at different viewing angles when the first hole group 122 is connected to the spray pipe 110 are respectively illustrated.

[0366] Fig.40 and Fig.41 The schematic diagrams of the structure of the second spray assembly provided in the embodiment of the present application at different viewing angles when the second hole group 123 is connected to the spray pipe 110 are respectively illustrated.

[0367] See also Figures 38 to 41 As shown, in some embodiments, the shower head 120 may have a plurality of hole groups on the side facing the inner barrel 50. The plurality of hole groups may include a first hole group 122 and a second hole group 123. The first hole group 122 and the second hole group 123 both have spray holes 121. The number of spray holes 121 in the second hole group 123 may be greater than the number of spray holes 121 in the first hole group 122.

[0368] Fig.42 yes Fig.39 Cross-sectional view in EE direction, Fig.43 yes Fig.41 Cross-sectional view in the FF direction.

[0369] See also Fig.42 and Fig.43 As shown, when the number of the spray holes 121 in the second hole group 123 can be greater than the number of the spray holes 121 in the first hole group 122, the size of the spray holes 121 in the second hole group 123 can be smaller than the size of the spray holes 121 in the first hole group 122. The size of the spray hole 121 can include but is not limited to the inner diameter of the spray hole 121. The inner diameter of the spray hole 121 can include but is not limited to the inner diameter of the spray hole 121 in the liquid inlet section 1211 and the liquid outlet section 1212.

[0370] Since the water flow effect generated by the hole group is related to the size of the spray hole 121, the larger the size of the spray hole 121, the more high-pressure liquid can be generated when the liquid in the liquid inlet pipeline is sprayed to the inner cylinder 50 through the hole group. In addition, the water flow effect generated by the hole group is also related to the size of the spray hole 121. The more the number of spray holes 121 in the hole group, the more dispersed the water flow generated when the liquid in the liquid inlet pipeline is sprayed to the inner cylinder 50 through the hole group, and the lower the pressure.

[0371] Therefore, by limiting the size and number of the spray holes 121 in the second hole group 123 and the first hole group 122, when the liquid in the liquid inlet pipeline is sprayed to the inner drum 50 through the first hole group 122 or the second hole group 123, two different water flow effects can be generated, so that the spray head 120 can generate a water flow efficiency adapted to the type of clothing, and wash, rinse, etc. the clothing.

[0372] The water flow effect generated by the first hole group 122 is more concentrated and the water flow pressure is greater, while the water flow effect generated by the second hole group 123 is more dispersed and the water flow pressure is smaller. The water flow generated by the first hole group 122 is suitable for washing clothes that require strong water flow for washing. The water flow generated by the second hole group 123 is suitable for washing clothes that require less water pressure.

[0373] For example, the first hole group 122 may have one spray hole 121, and the second hole group 123 may have two, three or four spray holes 121. Since the first hole group 122 has one spray hole 121, a single stream of water may be generated when the liquid in the liquid inlet pipeline is sprayed to the inner cylinder 50 via the first hole group 122. When the liquid in the liquid inlet pipeline is sprayed to the inner cylinder 50 via the second hole group 123, multiple streams of water with relatively low pressure may be generated.

[0374] The structure of the laundry processing device 10 is further described below by taking an example in which the first hole group 122 has one spray hole 121 and the second hole group 123 has four spray holes 121 .

[0375] In some embodiments, the spray assembly 100 may have a spray hole 126. The liquid in the liquid inlet pipeline may also be sprayed to the inner cylinder 50 through the spray hole 126 to expand the spraying area of ​​the spray assembly 100, thereby expanding the spraying area of ​​the spray assembly 100.

[0376] In addition to the spray area of ​​the spray hole 121, the spray area of ​​the spray assembly 100 may also include the spray area of ​​the spray hole 126. Accordingly, the spray area of ​​the spray assembly 100 may include the area occupied by the spray area of ​​the spray hole 121 and the spray area of ​​the spray hole 126.

[0377] Fig.44 and Fig.45 The schematic diagram shows the structure of the second spray assembly at different viewing angles when the third hole group 124 is connected to the spray pipe 110 . Fig.46 Shows Fig.45 Cross-sectional view in the GG direction.

[0378] See also Fig.44 and Fig.45 As shown, in some embodiments, the spray assembly 100 may further include an insert 125 .

[0379] See also Fig.46As shown, the shower head 120 may have an embedding hole. The embedding element 125 is embedded in the embedding hole, and the circumferential outer wall of the embedding element 125 and the hole wall of the embedding hole may together form a spray hole 126, so that the liquid in the liquid inlet pipeline can be sprayed from a circle around the circumference of the embedding element 125 into the inner drum 50, so as to form a closed waterfall-like water flow effect around the circumference of the embedding element 125. On the basis of the first hole group 122 and the second hole group 123, the diversity of the water flow effect can be further enhanced to adapt to more types of clothing.

[0380] In some embodiments, the plurality of hole groups may further include a third hole group 124. The third hole group 124 may have at least one spray hole 126. Through the arrangement of the first hole group 122, the second hole group 123 and the third hole group 124 in the plurality of hole groups, the laundry treatment device 10 can generate a plurality of different water flow effects during washing, rinsing and other procedures.

[0381] The pressure of the water flow generated by the spray holes 126 is lower than the pressure of the water flow generated by the second hole group 123 . Therefore, the water flow generated by the third hole group 124 is suitable for washing clothes that require gentle water flow.

[0382] For example, the third hole group 124 may have one, two, or the like spray holes 126. Each spray hole 126 may be provided with a corresponding insert 125. The structure of the laundry processing device 10 is further described below by taking one spray hole 126 as an example.

[0383] For example, the insert 125 may be a structural member such as a screw or a bolt that can be installed on the shower head 120 by screwing.

[0384] See also Fig.45 As shown, in the second spray assembly, the spray head 120 can be rotated relative to the fixing member 130 so that the spray pipe 110 is connected to one of the multiple hole groups, so that the user can rotate the spray head 120 according to the demand of the clothes for water flow, and select one of the hole groups to be connected to the spray pipe 110, so that when the clothing processing device 10 is in the washing, rinsing and other programs, the water flow effect adapted to the washed clothes can be generated through the selected hole group.

[0385] For example, when the washed clothes require a gentle water flow, the user can rotate the spray head 120 to connect the third hole group 124 with the spray pipe 110; when the washed clothes require multiple streams of water with lower pressure, the user can rotate the spray head 120 to connect the second hole group 123 with the spray pipe 110; when the washed clothes require a strong water flow, the user can rotate the spray head 120 to connect the first hole group 122 with the spray pipe 110.

[0386] It should be noted that, in addition to the demand for water flow by the clothes, the user can also select different hole groups to be connected to the spray pipe 110 according to different selected programs, so as to produce different water flow effects.

[0387] See also Fig.45 As shown, in some embodiments, the shower head 120 may have a buckle portion 127. The buckle portion 127 may be clamped on a side of the fixing member 130 facing the shower pipe 110, and the shower head 120 can rotate relative to the fixing member 130, so that the user can rotate the shower head 120.

[0388] See also Fig.45 and Fig.46 As shown, in some embodiments, the side of the fixing member 130 facing the shower head 120 may have a deformable protrusion 132. The protrusion 132 is located at the edge area of ​​the fixing member 130. The shower head 120 may have a positioning portion 129 on the side facing the fixing member 130 to engage the protrusion 132. The positioning portion 129 is located at the edge area of ​​the shower head 120.

[0389] See also Fig.44 As shown, the shower head 120 may be provided with a positioning portion 129 at a position corresponding to each hole group. The positioning portion 129 may be a groove on the shower head 120 or other structure capable of engaging the protrusion 132. The positioning portions 129 may be evenly distributed along the circumference of the shower head 120. When the shower head 120 is rotated relative to the fixing member 130 until the protrusion 132 is engaged in one of the positioning portions 129, the shower pipe 110 may be connected to one of the hole groups, and the hole group connected to the shower pipe 110 corresponds to the positioning portion 129 engaged with the protrusion 132.

[0390] In this way, when the shower head 120 rotates and the protrusion 132 has not rotated to the positioning portion 129, the shower head 120 will squeeze the protrusion 132 so that the protrusion 132 can be deformed toward one side of the shower pipe 110. When the protrusion 132 rotates to the positioning portion 129, the squeezing of the protrusion 132 by the shower head 120 disappears, and the protrusion 132 is clamped in the positioning portion 129, so that the hole group corresponding to the positioning portion 129 can be connected to the shower pipe 110. When the protrusion 132 rotates to the next positioning portion 129, the protrusion 132 will be deformed again under the squeezing of the shower head 120 until the protrusion 132 is clamped in the next positioning portion 129.

[0391] Therefore, by rotating the spray head 120, the protrusion 132 can be sequentially engaged with each positioning portion 129, and each hole group can be positioned, so that during the rotation process, each hole group can be sequentially connected to the spray pipe 110 to obtain a variety of different water flow effects.

[0392] See also Fig.45 As shown, in some embodiments, the fixing member 130 may be provided with a cantilever 133. The free end of the cantilever 133 faces the edge area of ​​the fixing member 130, and the side of the free end facing the spray head 120 may be provided with a protrusion 132, so that the protrusion 132 is arranged at the edge area of ​​the fixing member 130. At the same time, before the protrusion 132 rotates to the positioning portion 129, the spray head 120 will squeeze the protrusion 132, so that the cantilever 133 is deformed toward one side of the spray pipe 110, and the protrusion 132 is driven to deform toward one side of the spray pipe 110 at the same time, so as to ensure that the protrusion 132 can be deformed. When the protrusion 132 rotates to the positioning portion 129, the squeezing of the protrusion 132 by the spray head 120 disappears, and the protrusion 132 is reset toward one side of the spray head 120, and the cantilever 133 is driven to reset toward one side of the spray head 120 at the same time.

[0393] Alternatively, in some embodiments, the protrusion 132 may also be a flexible protrusion on the fixing member 130. In this case, while the protrusion 132 is deformed and snapped onto the positioning portion 129, there is no need to provide the cantilever 133 on the fixing member 130, which can simplify the structure of the fixing member 130.

[0394] The spray head 120 may be circular or square, etc. The structure of the clothes processing device 10 is further described below by taking the spray head 120 being circular as an example.

[0395] See also Fig.44 As shown, in some embodiments, along the radial direction of the shower head 120 , the protrusion 132 may be opposite to the connecting hole 131 of the fixing member 130 , and the protrusion 132 and the connecting hole 131 are located on both sides of the shower head 120 in the radial direction, so that the protrusion 132 is arranged at the edge area of ​​the fixing member 130 .

[0396] It should be noted that, along the radial direction of the shower head 120 , the protrusion 132 may be opposite to the connecting hole 131 of the fixing member 130 , which can be understood as that along the radial direction of the shower head 120 , the protrusion 132 and the connecting hole 131 are arranged opposite to each other.

[0397] When the shower head 120 rotates relative to the fixing member 130 until the protrusion 132 is engaged in one of the positioning portions 129 , the hole group connected to the shower pipe 110 can be connected to the shower pipe 110 through the connecting hole 131 .

[0398] See also Fig.44 As shown, along the radial direction of the shower head 120 , each hole group may be provided with a corresponding positioning portion 129 , and each hole group and the corresponding positioning portion 129 may be distributed on both sides of the shower head 120 in the radial direction.

[0399] The structure of the laundry processing device 10 is further described below by taking three hole groups as an example.

[0400] For ease of description, the positioning portion 129 corresponding to the first hole group 122 is defined as a first positioning portion 1291 , the positioning portion 129 corresponding to the second hole group 123 is defined as a second positioning portion 1292 , and the positioning portion 129 corresponding to the third hole group 124 is defined as a third positioning portion 1293 .

[0401] See also Fig.38 , Fig.39 and Fig.42 As shown, when the spray head 120 rotates relative to the fixing member 130 until the protrusion 132 is engaged in the first positioning portion 1291 , it means that the first hole group 122 is selected, and the first hole group 122 can be connected to the spray pipe 110 through the connecting hole 131 .

[0402] See also Fig.40 , Fig.41 and Fig.43 As shown, when the spray head 120 rotates relative to the fixing member 130 until the protrusion 132 is engaged in the second positioning portion 1292 , it means that the second hole group 123 is selected, and the second hole group 123 can be connected to the spray pipe 110 through the connecting hole 131 .

[0403] See also Figures 44 to 46 As shown, when the spray head 120 rotates relative to the fixing member 130 until the protrusion 132 is engaged in the third positioning portion 1293 , it means that the third hole group 124 is selected, and the third hole group 124 can be connected to the spray pipe 110 through the connecting hole 131 .

[0404] See also Fig.44 As shown, the centers of the first positioning portion 1291, the second positioning portion 1292 and the third positioning portion 1293 can be located on the first circumference. When the shower head 120 rotates relative to the fixing member 130, the first circumference can serve as a rotation track of the protrusion 132, so that when the shower head 120 rotates relative to the fixing member 130, the protrusion 132 can be engaged in any positioning portion 129.

[0405] Correspondingly, the centers of the first hole group 122, the second hole group 123, and the third hole group 124 may also be located on the second circumference. When the shower head 120 rotates relative to the fixing member 130, the second circumference may serve as a rotation track of the center of the connecting hole 131, so that when the shower head 120 rotates relative to the fixing member 130, the center of any hole group may coincide with the center of the connecting hole 131, so that any hole group may be connected to the shower pipe 110 through the connecting hole 131.

[0406] See also Fig.46As shown, in some embodiments, the spray assembly 100 may further include a seal 134. The seal 134 may be a sealing ring or other sealing structure. The seal 134 is disposed at the periphery of the communication hole 131 to seal the fixing member 130 and one of the hole groups. By providing the seal 134, the gap between the selected hole group and the fixing member 130 in the communication hole 131 can be sealed to prevent the liquid flowing through the communication hole 131 from entering the unselected hole group and affecting the water flow effect of the spray head 120.

[0407] In some embodiments, a portion of the seal 134 may be embedded on the side of the fixing member 130 facing the shower head 120 to achieve installation of the seal 134 on the fixing member 130. Alternatively, in other embodiments, the seal 134 may also be installed on the side of the fixing member 130 facing the shower head 120 by bonding or the like.

[0408] See also Fig.42 , Fig.43 and Fig.46 As shown, the side of the shower head 120 away from the fixing member 130 may have a plurality of protrusions 128. The number of protrusions 128 corresponds to the number of hole groups and corresponds one to one, and each protrusion 128 is provided with a hole group so that each hole group can be provided on the corresponding protrusion 128. In addition, when the user rotates the shower head 120, the protrusion 128 can be acted on, so that the user can apply force to the shower head 120, thereby rotating the shower head 120.

[0409] The projection areas of the protrusions 128 on the shower head 120 may be equal, that is, the areas of the holes in the shower head 120 may be equal. The shape of the end of the protrusion 128 facing the fixing member 130 may match the shape of the communication hole 131.

[0410] When the shape of one end of the protrusion 128 facing the fixing member 130 can match the shape of the connecting hole 131, the structure of the sealing member 134 can also match the shape of the connecting hole 131, so that the sealing member 134 can better seal the gap between the selected hole group and the fixing member 130 in the connecting hole 131.

[0411] Fig.47 The partial structural diagram of the second spray assembly in the clothes processing device 10 is schematically shown.

[0412] See also Fig.47 As shown, the second spray assembly is also arranged on the door seal 60, and the spray head 120 is arranged toward the inner cylinder 50. Specifically, the arrangement position and arrangement method of the second spray assembly 100 on the door seal 60 can refer to the relevant description of the first spray assembly above, which will not be repeated here.

[0413] Example 2

[0414] The washing water entering the shower head 120 generally contains lint. After the laundry treatment apparatus 10 is used for a long time, the lint is likely to gather in the shower head 120 and clog the shower head 120.

[0415] However, the existing spray head is fixedly connected to the water outlet end of the spray pipe, which makes it difficult to disassemble the spray head from the spray pipe and to clean the wire scraps accumulated in the spray head.

[0416] See also Fig.48 As shown, the embodiment of the present application also provides a spray assembly 100. The clothing processing device 10 of the embodiment of the present application may include a spray assembly 100. The spray assembly 100 includes a spray pipe 110, a fixing member 130 and a spray head 120, and the fixing member 130 is installed at the water outlet end of the spray pipe 110. The spray head 120 can be installed in the fixing member 130 by means of a clamping or screwing of a clamping member 140, so as to realize the detachable installation of the spray head 120 at the water outlet end of the spray pipe 11-. The user can release the clamping of the spray head 120 and the fixing member 130, or can realize the quick disassembly of the spray head 120 by screwing, so as to facilitate the user to clean and wash the impurities such as wire scraps in the spray head 120, prevent the spray head 120 from blocking or the dirt attached to its surface from contaminating the washing water, affecting the washing effect, and at the same time, can improve the user experience.

[0417] It should be noted that the spray assembly 100 can be installed at the water outlet end of the liquid inlet pipeline. For example, the spray pipe 110 can be installed at the water outlet end of the liquid inlet pipeline and can be connected to the water outlet end of the liquid inlet pipeline.

[0418] As described above, the liquid inlet pipeline may include a circulation pipeline 90 , a water inlet pipeline or other liquid inlet channels in the laundry treatment apparatus 10 .

[0419] The following further describes the structures of the spray assembly 100 and the clothing processing device 10 by taking the liquid inlet pipeline as the circulation pipeline 90 as an example.

[0420] Fig.49 The structural diagram of the first spray assembly provided in the embodiment of the present application is schematically shown.

[0421] Combine the following Fig.49 The structure of the first spray assembly and the clothes processing device 10 are further described.

[0422] See also Fig.49 As shown, the spray assembly 100 may include a spray pipe 110. The spray pipe 110 may be used to communicate with the water outlet end of the liquid inlet pipeline so that the liquid in the liquid inlet pipeline can enter the spray pipe 110.

[0423] The spray assembly 100 may include a fixing member 130 and a spray head 120. The fixing member 130 may be installed at the water outlet end of the spray pipe 110. The fixing member 130 has a cavity 1301 therein. The cavity 1301 is connected to the water outlet end of the spray pipe 110.

[0424] The spray assembly 100 may include a spray head 120. The spray head 120 may be disposed in the fixing member 130, and the spray head 120 may have a through hole and a spray hole 121. The spray hole 121 is connected to the cavity 1301 and faces the inner drum 50. In this way, the spray head 120 may be connected to the liquid inlet pipeline through the fixing member 130 and the spray pipe 110, so that the liquid in the liquid inlet pipeline may flow to the spray pipe 110, the cavity 1301 and the spray hole 121 in sequence, and finally the liquid is sprayed to the inner drum 50 through the spray hole 121, and the clothes are wetted to improve the washing effect.

[0425] In addition, part of the door body 30 usually protrudes toward one side of the inner drum 50, and the door seal 60 is located on the peripheral side of the protruding part of the door body 30. Therefore, the liquid sprayed into the inner drum 50 by the spray head 120 can not only flush the inner drum 50 over a larger area, but also flush the door body 30, the door seal 60, etc. over a larger area, so that the inner drum 50, the door seal 60, the door body 30, etc. are effectively flushed to avoid impurities such as foam generated by detergent from remaining in the inner drum 50, the door seal 60, and the door body 30, thereby improving the cleaning effect and ensuring the health of the user.

[0426] See also Fig.48 As shown, the spray pipe 110 can be passed through the door seal 60 and arranged on the side of the door seal 60 facing the top of the clothing processing device 10. For example, the spray pipe 110 can be passed through the door seal 60 and can face the side of the top of the housing 20. The spray head 120 is exposed on the inner side of the door seal 60 to facilitate the removal of the spray head 120. At the same time, the user can see the spray head 120 from the side facing the door seal 60, so that the water flow sprayed by the spray head 120 has the characteristic of visualization, so that the user can directly see the water flow effect sprayed by the spray head 120.

[0427] It should be noted that the inner side of the door seal 60 can be understood as the side of the door seal 60 facing the tube opening of the outer tube 40 along the radial direction of the outer tube 40 .

[0428] See also Fig.48 As shown, in some embodiments, the laundry processing device 10 may further include a connecting device. The connecting device may be a three-way valve or the like. The connecting device is disposed in the housing 20. The connecting device may selectively connect the water outlet of the drain pump 70 to the water inlet of the circulation pipeline 90 and the water inlet of the drain pipe 80.

[0429] When the mixture in the inner drum 50 and the outer drum 40 needs to be circulated and sprayed, the connecting device can connect the water outlet of the drain pump 70 with the water inlet of the circulation pipeline 90 and the water inlet of the drain pipe 80. The drain pump 70 is started, and the drain pump 70 pumps the mixture in the inner drum 50 and the outer drum 40 into the circulation pipeline 90, and directly reaches the spray head 120 upward. The mixture sprayed from the spray head 120 can wash the wall of the inner drum 50, the clothes in the inner drum 50, the door body 30, and the door seal 60.

[0430] When it is necessary to discharge the mixture in the inner cylinder 50 and the outer cylinder 40 to the outside of the housing 20, the connecting device can connect the water outlet of the drain pump 70 with the water inlet of the drain pipe 80. When the drain pump 70 is started, the drain pump 70 pumps the mixture in the inner cylinder 50 and the outer cylinder 40 into the drain pipe 80, and the mixture can be discharged to the outside of the housing 20 through the drain pipe 80.

[0431] It should be noted that the structure of the communication device can be determined according to the structure of the clothing processing device 10 in the related art, and will not be described in detail in this application. During the washing, rinsing and dehydration process of the clothing processing device 10, the liquid in the liquid inlet pipeline can be sprayed out from the spray hole 121 at any time according to the program design of the clothing processing device 10 to flush the wall of the inner drum 50, the clothes in the inner drum 50, the door body 30, and the door seal 60.

[0432] See also Fig.49 As shown, in some embodiments, the spray assembly 100 may further include a clamping member 140 . The clamping member 140 may be inserted into the insertion hole and clamped with the fixing member 130 to install the spray head 120 in the fixing member 130 .

[0433] The clamping member 140 can realize the clamping connection between the spray head 120 and the fixing member 130, so that the spray head 120 can be installed in the fixing member 130 through the clamping member 140, and then the spray head 120 can be detachably installed on the water outlet end of the spray pipe 110 through the fixing member 130. When the spray head 120 needs to be disassembled, the user can release the clamping connection between the spray head 120 and the fixing member 130, so as to realize the rapid disassembly of the spray head 120, so as to facilitate the user to clean and wash the impurities such as wire scraps in the spray head 120, prevent the spray head 120 from being blocked or the dirt attached to its surface from contaminating the washing water, affecting the washing effect, and at the same time, improve the user experience.

[0434] The clamping member 140 may be a flexible member or a non-flexible member. When the clamping member 140 is a flexible member, when the shower head 120 needs to be disassembled, the user can act on the flexible member to deform the flexible member so that the flexible member can be smoothly removed from the hole. After the flexible member is removed from the hole, the clamping connection between the shower head 120 and the fixing member 130 can be released, thereby realizing the rapid disassembly of the shower head 120, so as to facilitate the user to clean and wash the impurities such as wire scraps in the shower head 120, prevent the shower head 120 from being blocked or the dirt attached to its surface from contaminating the washing water, affecting the washing effect, and at the same time, can improve the user experience.

[0435] The following text takes the clamping member 140 as an example of a flexible member to further define the structure of the clamping member 140 .

[0436] The clamping member 140 may be a rubber member with a certain hardness, or a plastic member with a certain flexibility.

[0437] See also Fig.49 As shown, in some embodiments, when the clamping member 140 is a flexible member, a clamping portion 141 and a pressing portion 142 may be respectively provided at two ends of the clamping member 140 .

[0438] Fig.50 Indicated Fig.49 Top view in the aa direction.

[0439] See also Fig.49 and Fig.50 As shown, the fixing member 130 may have a clamping portion 1303, and the clamping portion 1303 is located on the side of the spray head 120 facing the spray pipe 110. The clamping portion 141 may be clamped on the side of the clamping portion 1303 facing the spray pipe 110. Through the cooperation of the clamping portion 141 and the clamping portion 1303, the clamping member 140 can be installed on the fixing member 130.

[0440] See also Fig.49 As shown, in some embodiments, the side of the spray head 120 facing the spray pipe 110 may have a mounting portion 1201. The mounting portion 1201 may be disposed in the fixing member 130. One side of the mounting portion 1201 may abut against the side of the clamping portion 1303 away from the spray pipe 110, and the pressing portion 142 abuts against the other side of the mounting portion 1201, so that the mounting portion 1201 can be installed in the fixing member 130 and fixed relatively to the fixing member 130 through the cooperation of the clamping portion 1303 and the pressing portion 142, thereby realizing the detachable installation of the spray head 120 in the fixing member 130.

[0441] By setting the pressing portion 142, the user can press the pressing portion 142 to deform the pressing portion 142 when removing the shower head 120. At this time, the pressing portion 142 cannot press against the other side of the mounting portion 1201. Without the pressing portion 142 pressing against the mounting portion 1201, the mounting portion 1201 can be directly removed from the fixing member 130, so that the shower head 120 can be quickly removed.

[0442] See also Fig.49 As shown, the spray head 120 has a spray portion 1202 on a side away from the spray pipe 110. A spray hole 121 may be provided on the spray portion 1202. The axial direction of the spray hole 121 may be arranged at an angle with the length direction of the fixing member 130, so that the axial direction of the spray hole 121 is inclined toward the side away from the clamping member 140, so as to expand the spray area of ​​the spray hole 121, thereby expanding the spray area of ​​the spray hole 121 and the spray assembly 100, and improving the cleaning effect. The length direction of the fixing member 130 is parallel to the W direction.

[0443] The spraying region of the spraying assembly 100 may include the spraying region of the spraying hole 121. Accordingly, the spraying area of ​​the spraying assembly 100 may include the area occupied by the spraying region of the spraying hole 121.

[0444] See also Fig.50 As shown, in some embodiments, the number of the spray holes 121 can be multiple. For example, the number of the spray holes 121 can be two, three, four, etc. Along the circumference of the spray head 120, the multiple spray holes 121 can be evenly distributed on the spray part 1202, so that the water flow generated by the liquid in the liquid inlet pipeline spraying through the spray holes 121 is more uniform, so as to further expand the spray area of ​​the spray assembly 100, so as to achieve a large area coverage of the clothes in the inner drum 50, improve the washing effect, and at the same time, can wash the inner drum 50, the door seal 60, and the door body 30 over a large area, improve the washing effect, and ensure the health of the clothes user.

[0445] See also Fig.49 and Fig.50 As shown, in some embodiments, the fixing member 130 may include a first fixing portion 1304, a second fixing portion 1305 and a connecting rib that are connected to each other. The first fixing portion 1304 may be installed at the water outlet end of the spray pipe 110. For example, the first fixing portion 1304 may be installed at the water outlet end of the spray pipe 110 by means of a threaded connection, a clamping connection or a welding structure. The second fixing portion 1305 may be arranged in the first fixing portion 1304 and connected to the first fixing portion 1304 by means of a connecting rib. The circumferential outer wall of the second fixing portion 1305 and the circumferential inner wall of the first fixing portion 1304 together form a cavity 1301. The first fixing portion 1304 has a connecting hole at one end facing the spray pipe 110, and the cavity 1301 may be connected to the spray pipe 110 through the connecting hole.

[0446] The mounting portion 1201 is disposed in the second fixing portion 1305, and the second fixing portion 1305 may have a clamping portion 1303 at one end facing the spray pipe 110. The clamping portion 1303 has a first opening, and the clamping portion 141 may penetrate the through hole and the first opening, and be clamped to the side of the clamping portion 1303 facing the spray pipe 110, so that the spray head 120 and the fixing member 130 can be detachably connected through the cooperation of the clamping portion 1303 and the pressing portion 142.

[0447] Fig.51 Schematically shows Fig.49 Schematic diagram of the disassembly process of the middle sprinkler head 120. Fig.49 and Fig.51 As shown, in order to facilitate the deformation of the clamping member 140, the clamping member 140 may have a cavity, and a second opening communicating with the cavity is provided in the clamping portion 141, so that when the pressing portion 142 is pressed, the pressing portion 142 can be deformed. Furthermore, when the user acts on the pressing portion 142 to pull the clamping member 140 out of the through hole, the clamping portion 141 can be deformed toward one side of the second opening, so that the clamping portion 141 contracts, so that the clamping portion 141 can pass through the through hole, and the clamping member 140 can be smoothly removed from the through hole.

[0448] Fig.52 Schematically shows Fig.49 Schematic diagram of the installation process of the middle sprinkler head 120. Fig.49 and Fig.52 As shown, when the user installs the shower head 120, the installation portion 1201 of the shower head 120 can be first installed in the second fixing portion 1305, and then the clamping member 140 can be inserted into the insertion hole so that the clamping portion 141 abuts against the clamping portion 1303, and at the same time, the pressing portion 142 presses the installation portion 1201 to achieve the installation of the shower head 120 in the fixing member 130. Alternatively, the user can also first insert the clamping member 140 into the insertion hole, and then install the clamping member 140 and the shower head 120 together in the second fixing portion 1305, and achieve the clamping connection between the shower head 120 and the second fixing portion 1305 through the clamping member 140.

[0449] See also Fig.52As shown, in some embodiments, the clamping member 140 may have a deformable connecting arm in the circumferential direction. The connecting arm may form a pressing portion 142. Alternatively, the end of the clamping member 140 away from the spray pipe 110 may form the pressing portion 142 as a whole. Compared with the end of the clamping member 140 away from the spray pipe 110 may form the pressing portion 142 as a whole, when the connecting arm forms the pressing portion 142, while ensuring that the pressing portion 142 can press against the mounting portion 1201, it is also convenient for the user to accurately press the pressing portion 142, so that the pressing portion 142 can be deformed faster, so as to further improve the disassembly efficiency of the spray head 120.

[0450] In some embodiments, the clamping member 140 may have at least two pressing portions 142. For example, the number of the pressing portions 142 may be two. At least two pressing portions 142 may be spaced and distributed around the circumference of the clamping member 140 so that the pressing portions 142 are subjected to a more uniform force, so that the pressing portions 142 can be deformed more quickly, thereby further improving the disassembly efficiency of the shower head 120. Alternatively, the number of the pressing portions 142 may be one, in which case the pressing portion 142 may be a closed structure arranged around the circumference of the clamping portion 141.

[0451] In some embodiments, the spray assembly 100 may have a spray hole. For example, the spray hole may include a first spray hole 143, a second spray hole 1203, etc. The liquid in the liquid inlet pipeline may also be sprayed to the inner cylinder 50 through the spray hole to expand the spray area of ​​the spray assembly 100, thereby expanding the spray area of ​​the spray assembly 100.

[0452] When the spray assembly 100 includes a spray hole, the spray area of ​​the spray assembly 100 also includes the spray area of ​​the spray hole in addition to the spray area of ​​the spray hole 121. Accordingly, the spray area of ​​the spray assembly 100 includes not only the area occupied by the spray area of ​​the spray hole 121, but also the area occupied by the spray area of ​​the spray hole.

[0453] Fig.53 The schematic diagram shows the water flow effect produced by the first type of spray assembly. Fig.53 As shown, in some embodiments, the clamping member 140 may have a first spray hole 143. The first spray hole 143 is connected to the cavity 1301 and faces the inner cylinder 50, so that the liquid in the liquid inlet pipeline can also be sprayed to the inner cylinder 50 through the first spray hole 143 to expand the spray area of ​​the spray assembly 100, thereby expanding the spray area of ​​the spray assembly 100 and improving the cleaning effect.

[0454] It should be noted that, in some embodiments, the first spray hole 143 may not be provided on the clamping member 140. The structure of the first spray assembly is further described below by taking the first spray hole 143 on the clamping member as an example.

[0455] See also Fig.53 As shown, in some embodiments, the end of the fixing member 130 away from the spray pipe 110 can be an open end 1302 connected to the cavity 1301. The spray part 1202 can be arranged in the open end 1302, and the circumferential outer wall of the spray part 1202 and the circumferential inner wall of the open end 1302 together form a second spray hole 1203. Among them, the second spray hole 1203 is connected to the cavity 1301 and faces the inner cylinder 50, so that the liquid in the liquid inlet pipeline can also be sprayed to the inner cylinder 50 through the second spray hole 1203, further expanding the spray area of ​​the spray assembly 100 and improving the cleaning effect. At the same time, since the second spray hole 1203 is located at the periphery of the spray hole 121, the spray hole 121 can cooperate with the second spray hole 1203 to enhance the flushing effect of the inner cylinder 50, the door seal 60, and the door body 30, further improve the cleaning effect, and ensure the health of the user.

[0456] See also Fig.53 As shown, in some embodiments, along the circumference of the spray head 120, there may be a gap between the circumferential outer wall of the spray portion 1202 and the circumferential inner wall of the open end 1302, and the circumferential outer wall of the spray portion 1202 and the circumferential inner wall of the open end 1302 may together form an annular hole. The annular hole forms the second injection hole 1203, so that the liquid in the liquid inlet pipeline can also be injected into the inner cylinder 50 through the second injection hole 1203.

[0457] The second spray hole 1203 may be a tapered hole having a small diameter end and a large diameter end, wherein the small diameter end faces the spray pipe 110 and the large diameter end faces the inner cylinder 50, so as to ensure that the liquid in the liquid inlet pipeline can also be sprayed to the inner cylinder 50 through the second spray hole 1203, and the spraying area of ​​the spray assembly 100 can be expanded.

[0458] See also Fig.53 As shown, the shape formed by the circumferential inner wall of the opening end 1302 can be a cone, which also has a small diameter end and a large diameter end, the small diameter end faces the spray pipe 110, and the large diameter end faces the inner cylinder 50. The shape formed by the circumferential outer wall of the spray part 1202 matches the shape formed by the circumferential inner wall of the opening end 1302.

[0459] When the shape formed by the circumferential outer wall of the spray portion 1202 matches the shape formed by the circumferential inner wall of the opening end 1302 , the shape formed by the circumferential outer wall of the spray portion 1202 is also conical, and similarly the small diameter end faces the spray pipe 110 and the large diameter end faces the inner cylinder 50 .

[0460] Alternatively, the shape formed by the circumferential inner wall of the opening end 1302 may be cylindrical, and in this case, the shape formed by the circumferential outer wall of the spray portion 1202 may also be cylindrical.

[0461] Compared with the cylindrical shape formed by the circumferential inner wall of the opening end 1302, when the shape formed by the circumferential inner wall of the opening end 1302 is conical, while ensuring that the liquid in the liquid inlet pipeline is sprayed into the inner cylinder 50 through the second spray hole 1203, the spraying area of ​​the second spray hole 1203 and the spray assembly 100 can be expanded, thereby expanding the spraying area of ​​the second spray hole 1203 and the spray assembly 100.

[0462] In some embodiments, along the circumference of the spray head 120 , the gap between the circumferential outer wall of the spray portion 1202 and the circumferential inner wall of the opening end 1302 can also be divided into a plurality of independent small second spray holes 1203 , which can also spray the liquid in the liquid inlet pipeline into the inner cylinder 50 .

[0463] Compared with the multiple second injection holes 1203 between the circumferential outer wall of the spray part 1202 and the circumferential inner wall of the opening end 1302, when the circumferential outer wall of the spray part 1202 and the circumferential inner wall of the opening end 1302 jointly form a second injection hole 1203, the liquid in the liquid inlet pipeline can have a larger flow space in the second injection hole 1203, and impurities such as wire scraps are not easy to clog the second injection hole 1203.

[0464] On the basis of the above, the embodiment of the present application further provides a second spray assembly. Different from the first spray assembly mentioned above, in the second spray assembly, the spray head 120 is screwed into the fixing member 130 to achieve a detachable connection between the spray head 120 and the fixing member 130, and at the same time, the spray head 120 can open or block the second spray hole 1203 during the screwing process, so that the spray assembly 100 can spray water flow of different forms and intensities, so that the user can independently select the type of water flow according to personal needs or the type of clothes to be washed.

[0465] The differences of the second spray assembly are further described below in conjunction with the accompanying drawings and embodiments.

[0466] Fig.54 The schematic diagram shows the structure of the second spray assembly when the second spray hole 1203 is opened. Fig.55 The schematic diagram shows the structure of the second spray assembly when the second spray hole 1203 is gradually blocked. Fig.56 The schematic diagram shows the structure of the second spray assembly when the second spray hole 1203 is blocked.

[0467] See also Figure 54 to Figure 56As shown, as described above, the fixing member 130 has an open end 1302 connected to the cavity 1301 at one end away from the spray pipe 110. In some embodiments, the spray head 120 can be screwed into the fixing member 130 and fixed relatively to the fixing member 130. In other words, the spray head 120 is screwed into the fixing member 130, and the positions of the spray head 120 and the fixing member 130 are relatively fixed without the action of external force. For example, the mounting portion 1201 of the spray head 120 can be arranged in the second fixing portion 1305 and threadedly connected to the second fixing portion 1305, so that the spray head 120 is screwed into the fixing member 130, and at the same time, it can be ensured that the spray head 120 is relatively fixed to the second fixing portion 1305 without the action of external force.

[0468] The mounting portion 1201 may be provided with an external thread, and the second fixing portion 1305 may be provided with an internal thread, so that when the mounting portion 1201 is disposed in the second fixing portion 1305 , a threaded connection between the mounting portion 1201 and the second fixing portion 1305 can be achieved.

[0469] The spray part 1202 is disposed in the open end 1302, and the circumferential outer wall of the spray part 1202 and the circumferential inner wall of the open end 1302 can together form a second spray hole 1203. The spray part 1202 has a spray hole 121, and the shape of the spray hole 121 can be different from the second spray hole 1203. The spray hole 121 and the second spray hole 1203 are both connected to the cavity 1301 and face the inner cylinder 50, so that the liquid in the liquid inlet pipeline can enter the inner cylinder 50 through the spray hole 121 and the second spray hole 1203.

[0470] The mounting portion 1201 is a hollow structure communicating with the spray hole 121 and the cavity 1301 of the fixing member 130 , so that the spray hole 121 is communicated with the cavity 1301 through the mounting portion 1201 .

[0471] The second spray hole 1203 can be opened or blocked during the process of the spray head 120 being screwed into the fixing member 130 .

[0472] Since the spray head 120 is screwed into the fixing part 130, when the user needs to remove the spray head 120, the user can rotate the spray part 1202 to rotate the mounting part 1201 relative to the fixing part 130 toward the end away from the fixing part 130, and unscrew it from the second fixing part 1305, so as to release the connection between the spray head 120 and the fixing part 130, thereby realizing the rapid disassembly of the spray head 120, so as to facilitate the user to clean and wash the impurities such as lint in the spray head 120, prevent the spray head 120 from being blocked or the dirt attached to its surface from contaminating the washing water and affecting the washing effect, and at the same time, can improve the user experience.

[0473] Fig.57The partial structural diagram of the second spray assembly in the clothes processing device 10 is schematically shown.

[0474] See also Fig.56 and Fig.57 As shown, in some embodiments, the spray portion 1202 may have a recessed structure 1204 that is recessed toward one side of the spray pipe 110 , so that a user can act on the recessed structure 1204 of the spray portion 1202 to achieve rapid disassembly and assembly of the spray head 120 .

[0475] See also Figure 54 to Figure 56 As shown, since the second spray hole 1203 can be opened or blocked during the process of the spray head 120 being screwed into the fixing member 130, the liquid in the liquid inlet pipeline can enter the inner drum 50 through the spray hole 121 and the second spray hole 1203 at the same time during the process of the spray head 120 being screwed into the fixing member 130, or can enter the inner drum 50 only through the spray hole 121. The spray assembly 100 can form water flows of different forms and intensities, so that the user can independently select the type of water flow according to personal needs or the type of clothes to be washed.

[0476] The structure of the spray assembly 100 is further described below by taking the example of a user autonomously selecting the type of water flow according to the type of clothes to be washed.

[0477] For example, see Fig.54 As shown, when the spray head 120 is screwed into the fixing member 130 and the second spray hole 1203 is opened, the liquid in the liquid inlet pipeline can enter the inner drum 50 through the spray hole 121 and the second spray hole 1203 at the same time. At this time, a dispersed water flow can be formed, and the pressure of the water flow is relatively small, which is suitable for washing clothes that require a gentle water flow.

[0478] For example, see Fig.56 As shown, when the spray head 120 is screwed into the fixing member 130 and the second spray hole 1203 is blocked, the liquid in the liquid inlet pipeline can only enter the inner drum 50 through the spray hole 121. At this time, the water flow is more concentrated and the water pressure is relatively large, which is suitable for washing clothes that require strong water flow.

[0479] See also Fig.54 and Fig.56 As shown, the shower head 120 is screwed into the fixing member 130 and has an open position and a blocked position.

[0480] See also Fig.54As shown, when the spray head 120 is in the open position, along the circumference of the spray head 120, there is a gap connected to the outside between the circumferential outer wall of the spray part 1202 and the circumferential inner wall of the open end 1302 to open the second injection hole 1203, so that the liquid in the liquid inlet pipeline can enter the inner cylinder 50 through the spray hole 121 and the second injection hole 1203 at the same time, forming a dispersed water flow with low pressure.

[0481] See also Fig.56 As shown, when the spray head 120 is in the blocking position, along the circumference of the spray head 120, the circumferential outer wall of the spray portion 1202 contacts the circumferential inner wall of the opening end 1302 to block the second injection hole 1203, so that the liquid in the liquid inlet pipeline can only enter the inner cylinder 50 through the spray hole 121, forming a more concentrated and high-pressure water flow.

[0482] See also Fig.56 As shown, similar to the first type of spray assembly, the shape formed by the circumferential inner wall of the opening end 1302 is also conical, wherein the small diameter end may face the spray pipe 110, and the large diameter end may face the inner cylinder 50. The shape formed by the circumferential outer wall of the spray portion 1202 may match the shape formed by the circumferential inner wall of the opening end 1302. In other words, the shape formed by the circumferential outer wall of the spray portion 1202 may also be conical, and have a small diameter end and a large diameter end.

[0483] The difference is that when the shower head 120 is in the blocking position, the circumferential outer wall of the shower part 1202 and the circumferential inner wall of the opening end 1302 are in conical contact, so as to block the second spray hole 1203 by the cooperation between the shower part 1202 and the opening end 1302. For example, the large diameter end of the circumferential outer wall of the shower part 1202 can be in conical contact with the circumferential inner wall of the opening end 1302.

[0484] It should be noted that when the spray head 120 is in the open position, the large diameter end of the circumferential outer wall of the spray portion 1202 can be located outside the opening end 1302, so that the large diameter end of the circumferential outer wall of the spray portion 1202 can protrude from the fixing part 130, so that the user can quickly find the fixing part 130 and realize the rapid disassembly of the spray head 120.

[0485] See also Figure 54 to Figure 56As shown, when the user needs concentrated and high-pressure water flow, the user can rotate the spray head 120 so that the spray head 120 is screwed toward the side close to the spray pipe 110. During the screwing process, the large-diameter end of the cone formed by the circumferential outer wall of the spray part 1202 continuously moves toward the side close to the spray pipe 110, and the second spray hole 1203 is gradually blocked. When the large-diameter end of the cone formed by the circumferential outer wall of the spray part 1202 contacts the circumferential inner wall of the opening end 1302 during the screwing process of the spray head 120, the spray head 120 is located in the blocking position, and the second spray hole 1203 is blocked.

[0486] Correspondingly, when the user needs a dispersed and low-pressure water flow, the spray head 120 can also be rotated so that the spray head 120 is rotated toward the side away from the spray pipe 110. During the process of screwing, the large-diameter end of the cone formed by the circumferential outer wall of the spray part 1202 continuously moves toward the side away from the spray pipe 110. When the large-diameter end of the cone formed by the circumferential outer wall of the spray part 1202 does not contact the circumferential inner wall of the opening end 1302, the spray head 120 is in the open position and the second spray hole 1203 is opened.

[0487] See also Fig.56 As shown, similar to Embodiment 1, in this embodiment, along the flow direction of the liquid in the spray hole 121:

[0488] The spray hole 121 has a liquid inlet section 1211 and a liquid outlet section 1212 , wherein the liquid inlet section 1211 may be in a contraction structure, and the liquid outlet section 1212 may be in an expansion structure.

[0489] Alternatively, in some other embodiments, along the flow direction of the liquid in the spray hole 121:

[0490] The inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212 may be equal.

[0491] Compared with the equal inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212, when the liquid inlet section 1211 presents a contraction structure and the liquid outlet section 1212 presents an expansion structure along the flow direction of the liquid in the spray hole 121, the pressure of the water flow generated by the spray hole 121 can be instantly increased.

[0492] It should be noted that the reason why the pressure of the water flow generated by the spray hole 121 can be instantly increased by setting a contraction structure in the liquid section 1211 and an expansion structure in the liquid outlet section 1212 can be seen in the relevant description in Example 1 and will not be repeated here.

[0493] Specifically, along the flow direction of the liquid in the spray hole 121, the liquid inlet section 1211 is in a contraction structure, and the liquid outlet section 1212 is in an expansion structure. Along the flow direction of the liquid in the spray hole 121, the cross-sectional area of ​​the liquid inlet section 1211 gradually decreases, and the cross-sectional area of ​​the liquid outlet section 1212 gradually increases. The cross-sectional areas of the spray hole 121 in the liquid inlet section 1211 and the liquid outlet section 1212 can be formed by the same cross section. The cross section is perpendicular to the length direction of the fixing member 130 (see the W direction).

[0494] Along the flow direction of the liquid in the spray hole 121, the inner diameter of the liquid inlet section 1211 gradually decreases, and the inner diameter of the liquid outlet section 1212 gradually increases, and the inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212 at the opposite ends are equal, so that along the flow direction of the liquid in the spray hole 121, the cross-sectional area of ​​the liquid inlet section 1211 gradually decreases, and the cross-sectional area of ​​the liquid outlet section 1212 gradually increases. In addition, since the inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212 at the opposite ends are equal, the inner diameter of the spray hole 121 can also smoothly transition between the liquid inlet section 1211 and the liquid outlet section 1212, so as to ensure that the liquid can flow to the liquid outlet section 1212 along the predetermined water flow direction. At the same time, since the inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212 at the opposite ends are equal, the spray hole 121 forms a narrow channel between the liquid inlet section 1211 and the liquid outlet section 1212. When the liquid flows to the narrow channel through the liquid inlet section 1211, the flow of the liquid is at the critical point mentioned above.

[0495] The liquid inlet section 1211 can be directly connected to the liquid outlet section 1212. Alternatively, the spray hole 121 can also have a connecting section, and the liquid inlet section 1211 and the liquid outlet section 1212 are connected in the connecting section. Along the flow direction of the liquid in the spray hole 121, the inner diameters of the connecting section are equal, and the inner diameter of the connecting section is equal to the minimum inner diameter of the liquid inlet section 1211 and the liquid outlet section 1212, so that the inner diameters of the hole wall of the spray hole 121 in the liquid inlet section 1211 and the liquid outlet section 1212 can be smoothly transitioned with the connecting section to ensure that the liquid can flow to the liquid outlet section 1212 along the predetermined water flow direction. In addition, by directly connecting the liquid inlet section 1211 to the liquid outlet section 1212, or by providing the connecting section, the structure of the spray hole 121 can be made more diversified to meet the design requirements of different spray heads 120 for the spray hole 121.

[0496] Compared with the setting of the connecting section, when the liquid inlet section 1211 can be directly connected to the liquid outlet section 1212, the pressure of the liquid is instantly increased, the spraying area is increased, and the length of the spray hole 121 in the W direction can be reduced, which is beneficial to reducing the size of the spray head 120 in the W direction and realizing the miniaturization of the spray head 120.

[0497] It should be noted that, in some embodiments, other openings may be provided at other positions of the spray part 1202 , and these openings may be connected to the cavity 1301 of the fixing member 130 . These openings may always be in an open state, and may be opened or closed to further expand the spraying area of ​​the spray assembly 100 .

[0498] Example 3

[0499] Based on the fact that the spray holes on the spray heads in the related art are usually round holes, the coverage area and pressure of the mixed liquid sprayed out through the spray holes are limited, making it difficult to wash clothes efficiently. The washing effect of the clothes processing equipment needs to be improved. See Fig.58 As shown, the spray assembly in the clothing processing device of the embodiment of the present application includes a spray head connected to the water outlet end of the liquid inlet pipeline, a moving part and an extruding part. The shape of the spray hole of the spray head is changed by the moving part and the extruding part, so that the pressure of the liquid can be instantly increased when the liquid is sprayed through the spray hole, and a large spraying area is provided, so that the liquid sprayed by the spray head to the inner drum can cover a large area and rinse the clothes in the inner drum, which can efficiently wash the clothes and improve the washing effect. At the same time, the liquid sprayed by the spray head to the inner drum can also rinse the inner drum, door seal, door body, etc., to avoid impurities such as foam generated by the detergent remaining in the inner drum and the door body, thereby ensuring the washing effect of the clothes and the health of the user.

[0500] The structures of the spray assembly and the clothes processing device having the moving parts and the extruding parts are further described below in conjunction with the accompanying drawings and embodiments.

[0501] See also Fig.59 As shown, the laundry processing device comprises a liquid inlet pipeline 90 and a spray assembly 100. The structure of the liquid inlet pipeline 90 is as described above.

[0502] Fig.60 This is a schematic diagram of the structure of a spray assembly when the spray head is not squeezed, provided in an embodiment of the present application. Fig.61 A schematic diagram of the structure of a spray assembly after a spray head is squeezed provided in an embodiment of the present application.

[0503] Combination Fig.60 As shown, the spray assembly 100 includes a spray head 120, a moving part 150 and an extruding part 160. The spray head 120 is connected to the water outlet end of the liquid inlet pipeline 90. The liquid in the liquid inlet pipeline 90 is sprayed to the inner drum through the spray head 120, so that the liquid in the liquid inlet pipeline 90 can be sprayed into the inner drum through the spray head 120, thereby washing the clothes in the inner drum. The spray head 120 has a spray hole 121 for spraying liquid, so that the liquid in the liquid inlet pipeline 90 can be sprayed into the inner drum through the spray hole 121, thereby washing the clothes in the inner drum.

[0504] The moving part 150 may be disposed around the outer periphery of the spray head 120, and the moving part 150 may reciprocate along the second direction, wherein the second direction (i.e., the Z direction in the figure) is the flow direction of the liquid in the spray hole 121. The extrusion part 160 may be located between the spray head 120 and the moving part 150, and the extrusion part 160 may be located between the spray head 120 and the moving part 150. Fig.61 As shown, the spray hole 121 has a liquid inlet section 1211 and a liquid outlet section 1212, and the extrusion member 160 is configured to squeeze and deform the spray head 120 during the movement of the moving member 150, so that the liquid inlet section 1211 is in a contracted state in the second direction, and the liquid outlet section 1212 is in an expanded state in the second direction.

[0505] Through the cooperation of the moving part 150 and the extruding part 160, the cross-sectional area of ​​the liquid inlet section 1211 of the spray hole 121 can be gradually reduced, and the cross-sectional area of ​​the liquid outlet section 1212 can be gradually increased along the flow direction of the liquid in the spray hole 121. The cross-sectional areas of the liquid inlet section 1211 and the liquid outlet section 1212 of the spray hole 121 can be formed by the same cross section. The cross section is perpendicular to the axial direction of the spray hole 121. The axial direction of the spray hole 121 can refer to the Z direction.

[0506] It should be understood that, generally, when a liquid flows in a pipe, the flow rate of the liquid is inversely proportional to the cross-sectional area of ​​the pipe.

[0507] The spray hole 121 can also be regarded as a kind of pipe. Since the cross-sectional area of ​​the liquid inlet section 1211 gradually decreases along the flow direction of the liquid in the spray hole 121, the flow velocity of the liquid in the liquid inlet section 1211 increases continuously during the flow of the liquid inlet section 1211. When the flow velocity of the liquid increases to a critical point in the liquid inlet section 1211, the flow velocity will not increase any more. At the critical point, the velocity of the fluid is greater than the speed of sound.

[0508] When the speed of the fluid is greater than the speed of sound, the above-mentioned inverse proportionality between the flow rate and the cross-sectional area of ​​the liquid is no longer applicable. Instead, it is just the opposite. The larger the cross-sectional area, the faster the flow rate of the liquid. Since the cross-sectional area of ​​the liquid outlet section 1212 gradually increases along the flow direction of the liquid in the spray hole 121, when the liquid enters the liquid outlet section 1212, the liquid continues to accelerate and becomes supersonic, so that the flow rate of the liquid can be instantly increased when the liquid is sprayed out through the spray hole 121. For the spray hole 121, the flow rate is proportional to the pressure. Therefore, when the flow rate of the liquid increases instantly, the pressure of the liquid also increases instantly, which can effectively rinse the clothes in the inner drum and improve the cleaning effect.

[0509] At the same time, since the cross-sectional area of ​​the liquid outlet section 1212 gradually increases along the flow direction of the liquid in the spray hole 121, the liquid has a larger spraying area when it is sprayed into the inner drum through the liquid outlet section 1212, so that the liquid sprayed into the inner drum through the spray hole 121 can cover a large area and rinse the clothes in the inner drum, which can efficiently wash the clothes and improve the cleaning effect.

[0510] In addition, the liquid sprayed into the inner drum by the spray head 120 has a higher pressure and a larger spraying area, and part of the door body usually protrudes toward one side of the inner drum, and the door seal is located on the peripheral side of the protruding part of the door body. Therefore, the liquid sprayed into the inner drum by the spray head 120 can not only flush the inner drum over a larger area, but also flush the door body, door seal, etc. over a larger area, thereby effectively flushing the inner drum, door seal, door body, etc., to avoid impurities such as foam generated by detergent from remaining in the inner drum, door seal, and door body, thereby improving the cleaning effect and ensuring the health of clothing users.

[0511] When the liquid inlet pipeline 90 is a circulation pipeline, the liquid in the liquid inlet pipeline 90 is the mixed liquid in the circulation pipeline. The mixed liquid in the circulation pipeline can be sprayed into the inner drum through the spray hole 121, which can make the mixed liquid better soak into the clothes, help the clothes to better absorb the detergent in the mixed liquid, and at the same time, help the detergent to better disperse the stains attached to the surface of the clothes, thereby improving the cleaning effect. In addition, the mixed liquid can be sprayed on the clothes through the spray head 120, and the mixed liquid can also be hit on the clothes, effectively reducing the entanglement between the clothes, improving the cleaning effect, and at the same time, protecting the quality of the fabric of the clothes.

[0512] It should be noted that when the liquid inlet pipeline 90 is a circulation pipeline, it improves the cleaning effect and also has the characteristics of saving water. On the basis of achieving the same cleaning effect, compared with the clothes processing equipment in the related art, since the cleaning effect of the clothes processing equipment of the present application is improved, the clothes processing equipment of the present application also has the characteristics of saving time, saving electricity and reducing energy consumption.

[0513] When the liquid inlet pipeline 90 is a water inlet pipeline, the liquid in the liquid inlet pipeline 90 is water flowing into the water inlet pipeline from an external water source. The water inlet pipeline includes a water inlet pipe, a water inlet valve and a water inlet pipe branch. The water inlet pipe is connected to an external water source, and the water inlet valve is arranged between the water inlet pipe and the water inlet pipe branch. The water in the water inlet pipe can enter the water inlet pipe branch through the water inlet valve, and the water outlet end of the water inlet pipe branch is connected to the spray assembly 100. The water in the water inlet pipe branch can be sprayed into the inner drum through the spray hole 121, which can also better infiltrate the clothes and help the detergent to better disperse the stains attached to the surface of the clothes, thereby improving the washing effect. At the same time, when the water in the water pipeline can be sprayed into the inner drum through the spray hole 121, it can also effectively reduce the entanglement between the clothes, improve the washing effect, and protect the quality of the clothing fabric.

[0514] The structure of the clothing processing device is further described below by taking the liquid inlet pipeline 90 as a circulation pipeline as an example.

[0515] Continue to see Fig.61 As shown, the spray assembly 100 may further include a spray pipe 110, and the spray pipe 110 may include a first end 111 and a second end 112 opposite to each other, and the first end 111 may be connected to the water outlet end of the liquid inlet pipeline 90, and the spray head 120, the extrusion member 160 and the moving member 150 may all be connected to the second end 112 of the spray pipe 110, and the moving member 150 may be movably matched with the second end 112 of the spray pipe 110. For example, during the assembly process, the spray head 120, the extrusion member 160 and the moving member 150 may all be installed on the spray pipe 110 to form an assembly, and then the assembly may be connected to the liquid inlet pipeline 90 to complete the assembly of the spray assembly 100 in the clothes processing device.

[0516] The spray pipe 110 serves as a carrier of the spray assembly 100 and can provide an installation basis for the above-mentioned components. When the spray assembly 100 needs to be repaired, the spray assembly 100 can be removed from the liquid inlet pipeline 90 to repair the spray assembly 100, which can facilitate the installation and disassembly of the spray assembly 100 in the clothing processing equipment and facilitate the repair and maintenance of the spray assembly 100.

[0517] Fig.62 A schematic diagram of the structure of the connection between a moving part, an extrusion part and a spray pipe provided in an embodiment of the present application, Fig.63 for Fig.60 Magnified view of area B in the middle.

[0518] See also Fig.62 and Fig.63 As shown, the moving member 150 may include a connecting section 151, a transition section 152 and an extrusion section 153 connected in sequence. The inner diameter of the extrusion section 153 is smaller than the inner diameter of the connecting section 151, and the inner diameter of the transition section 152 gradually decreases along the second direction (i.e., the Z direction). The connecting section 151 can be movably matched with the second end 112 of the spray pipe 110, and the transition section 152 and the extrusion section 153 can be used to apply an extrusion force to the extrusion member 160.

[0519] Specific, combined Fig.63As shown, when the moving member 150 moves in the direction opposite to the second direction, since the diameter of the transition section 152 gradually decreases and the diameter of the extrusion section 153 is also small, the transition section 152 and the extrusion section 153 will squeeze the extrusion member 160, so that the extrusion member 160 squeezes and deforms the spray head 120, and the cross-sectional area of ​​the middle part of the spray head 120 (the middle part can be understood as the junction of the liquid inlet section 1211 and the liquid outlet section 1212) is reduced. In the second direction, the cross-sectional area of ​​the spray hole 121 gradually decreases in the liquid inlet section 1211, and the cross-sectional area of ​​the liquid outlet section 1212 gradually increases. The spray head 120 can achieve the effect of increasing pressure and increasing the spray area.

[0520] Among them, since the inner diameter of the transition section 152 is gradually reduced, therefore, in the process of the moving part 150 moving in the direction opposite to the second direction, the amount of extrusion of the transition section 152 on the extrusion member 160 is also gradually increased. Correspondingly, the amount of extrusion of the extrusion member 160 on the spray head 120 is also gradually increased, so that the inner diameter of the middle part of the spray hole 121 is gradually reduced. Among them, the inner diameter size of the middle part of the spray hole 121 is different, and the adjustment effect on the pressure and spray area of ​​the water flow is also different accordingly. Therefore, the moving part 150 can be moved to different positions so that the spray head 120 can spray water with different pressures and spray areas, which can effectively improve the flexibility of the adjustment of the spray head 120, so that the user can flexibly set it according to the requirements of the spray water pressure and spray area at the spray head 120.

[0521] The connecting section 151 may have a first threaded portion (not shown in the figure) on its outer periphery, and the inner wall of the second end 112 of the spray pipe 110 may have a second threaded portion (not shown in the figure) that matches the first threaded portion. For example, the first threaded portion may be an external thread, and the second threaded portion may be an internal thread, and the connecting section 151 may be connected to the spray pipe 110 through the cooperation of the first threaded portion and the second threaded portion.

[0522] Rotating the moving part 150 in this way can make the moving part 150 rotate and move along the spray pipe 110, so that the moving part 150 applies an extrusion force to the extrusion part 160. The threaded fit can conveniently control the movement amount of the moving part 150, so as to adjust the extrusion amount of the extrusion part 160 according to the movement amount of the moving part 150, and can effectively improve the accuracy of adjusting the water flow pressure and the spray area at the spray head 120.

[0523] Continue to see Fig.63As shown, the extrusion member 160 may include a connection ring 161, a connection rod 162 and an extrusion head 163, wherein the connection rod 162 is located between the connection ring 161 and the extrusion head 163, and one end of the connection rod 162 may be connected to the connection ring 161, and the other end may be connected to the extrusion head 163. The connection ring 161 may be connected to the spray pipe 110, so that the extrusion member 160 is connected to the spray pipe 110 through the connection ring 161. When the moving member 150 moves in a direction opposite to the second direction, one end of the connection rod 162 connected to the extrusion head 163 may deviate toward the direction of the spray head 120, so as to drive the extrusion head 163 to extrude toward the spray head 120.

[0524] The connecting rod 162 is a rod-shaped structure, has low rigidity and strength, and is easy to deform. During the movement of the moving part 150, as the pressure applied by the moving part 150 to the extrusion head 163 increases, the connecting rod 162 can be offset, so that the extrusion head 163 moves toward the spray head 120, so that the extrusion head 163 can squeeze the spray head 120. The cross section of the middle part of the spray head 120 is squeezed and reduced, and the inner diameter of the liquid inlet section 1211 of the spray head 120 is gradually reduced, and the inner diameter of the liquid outlet section 1212 is gradually increased. Therefore, the spray head 120 can achieve the effect of increasing pressure and increasing the spray area.

[0525] Continue to see Fig.63 As shown, the number of the connecting rod 162 and the extrusion head 163 can be two, and the two connecting rods 162 and the extrusion head 163 can be respectively located on both sides of the spray head 120. In this way, during the movement of the moving part 150, the extrusion heads 163 located on both sides of the spray head 120 can respectively squeeze the spray head 120 from both sides, so that the spray head 120 can be simultaneously reduced inward from both sides to reduce the cross-sectional area of ​​the middle part of the spray head 120. In this way, the uniformity and symmetry of the deformation of the spray head 120 can be improved, so that the liquid can be sprayed outward more evenly after passing through the spray head 120, which helps to improve the spraying effect of the spray head 120.

[0526] Continue to see Fig.63 As shown, the spray assembly 100 may further include a support member 130a, which is connected to the spray pipe 110, and the spray head 120 may be sleeved on the support member 130a. The support member 130a may support and fix the spray head 120, thereby reducing or preventing the spray head 120 from deforming or falling.

[0527] Fig.64 A structural schematic diagram of a support member provided in an embodiment of the present application, Fig.65 A schematic diagram of the structure of a support member and a shower head provided in an embodiment of the present application.

[0528] Among them, see Fig.64 and Fig.65 As shown, the support member 130a may include a first support ring 131a and a second support ring 132a disposed at intervals, and a support bar 133a may be provided between the first support ring 131a and the second support ring 132a. The first support ring 131a may be connected to the second end 112 of the spray pipe 110, so that the support member 130a may be connected to the spray pipe 110 through the first support ring 131a. Fig.63 As shown, two ends of the shower head 120 are respectively connected to the first support ring 131 a and the second support ring 132 a to achieve installation and fixation of the shower head 120 .

[0529] The support strip 133a can play a fixing role in the axial direction (ie, the second direction) of the shower head 120, and the first support ring 131a and the second support ring 132a can play a supporting role in the circumferential direction of the shower head 120 to prop up the shower head 120 so that there is always a channel for water flow inside the shower head 120.

[0530] Continue to see Fig.64 As shown, a first boss 1311a may be provided around the outer periphery of the first support ring 131a, and a second boss 1321a may be provided around the outer periphery of the second support ring 132a. Fig.65 As shown, the two ends of the shower head 120 can be respectively sleeved on the first boss 1311a and the second boss 1321a. The first boss 1311a and the second boss 1321a can limit and fix the two ends of the shower head 120, which can effectively reduce or prevent the two ends of the shower head 120 from falling off the first support ring 131a and the second support ring 132a, and can effectively improve the reliability and firmness of the connection between the shower head 120 and the first support ring 131a and the second support ring 132a.

[0531] The number of the support bars 133a in the support member 130a may also be two, and the two support bars 133a may be respectively located on both sides of the shower head 120, and the line between the two support bars 133a is perpendicular to the line between the two extrusion heads 163. In other words, the two support bars 133a and the two extrusion heads 163 are respectively located in two mutually perpendicular radial directions of the shower head 120. In this way, interference between the support bars 133a and the extrusion heads 163 can be avoided, thereby affecting the extrusion of the shower head 120 by the extrusion heads 163, which helps to improve the reliability and stability of the extrusion of the shower head 120 by the extrusion member 160.

[0532] Example 4

[0533] The existing spray head is fixed on the clothing processing equipment. The spray area of ​​the spray head is small, and there may be places where the washing water cannot be sprayed, resulting in residual detergent foam or other impurities on the inner drum, door seal and door body. Over time, these impurities will become moldy and smelly, affecting the health of users.

[0534] In order to solve the above-mentioned problems, the clothing processing device in the embodiment of the present application is provided with a movable component in the clothing processing device. The movable component can move under the power provided by the liquid flowing in the spray pipe. The movable component can drive the spray head to swing. The spraying area can be expanded by the swinging of the spray head, so that the inner drum, door seal and door body can be effectively rinsed, so as to avoid impurities such as foam generated by detergent from remaining on the inner drum, door seal and door body, thereby improving the cleaning effect and ensuring the health of the user.

[0535] The structure of the clothing processing device is further described below by taking the liquid inlet pipeline as the circulation pipeline 90 as an example.

[0536] See also Fig.66 As shown, the laundry treatment apparatus may further include a connecting device 200. The connecting device 200 is disposed in the housing 20. The connecting device 200 may selectively connect the water outlet of the drain pump 70 with the water inlet of the circulation pipeline 90 and the water inlet of the drain pipe 80.

[0537] The spray pipe 110 can be fixed to the water outlet end of the circulation pipeline 90 by means of clamping, threading, welding, etc., and communicated with the water outlet end of the circulation pipeline 90. The spray pipe 110 can be passed through and fixed on the door seal 60, and the water outlet end of the spray pipe 110 can be directed toward the inner cylinder 50 relative to the rest of the spray pipe 110. In some examples, see Fig.67 As shown, the spray pipe 110 includes a first section 111 and a second section 112, the first section 111 and the second section 112 are intersected and connected, the first section 111 is connected to the water outlet end of the circulation pipeline 90, the first section 111 is passed through and fixed on the door seal 60, and the water outlet end of the second section 112 faces the inner tube 50.

[0538] The spray pipe 110 further includes a mounting cover 170.

Figures 68 to 70 The mounting cover 170 is indicated by a dotted line.

[0539] See also Fig.68 As shown, the spray head 120 is rotatably mounted on the water outlet end of the spray pipe 110. Specifically, the spray head 120 is rotatably mounted on the water outlet end of the second section 112 of the spray pipe 110.

[0540] The liquid in the circulation pipeline 90 is sprayed to the inner cylinder 50 through the spray pipe 110 and the spray head 120 .

[0541] The spray head 120 is provided with a rotating shaft 121a. The rotating shaft 121a is rotatably connected to the second section 112 of the spray pipe 110. The spray head 120 can swing relative to the water outlet end of the second section 112 through the rotating shaft 121a.

[0542] The shower head 120 is at least partially installed inside the second section 112. Exemplarily, the shower head 120 is mostly installed inside the second section 112 to prevent the shower head 120 from being deformed or falling off due to friction or squeezing of clothing or the like.

[0543] Since the spray pipe 110 is passed through and fixed to the door seal 60, the water outlet end of the second section 112 faces the inner cylinder 50. The spray head 120 is located at the water outlet end of the second section 112 of the spray pipe 110. The spray head 120 can be located on the side of the door seal 60 facing the inner cylinder, so that the liquid in the spray pipe 110 can be sprayed into the inner cylinder 50 through the spray head 120, and the user can also observe the spraying effect of the spray head 120 through the door body 30.

[0544] See also Fig.68 As shown, the clothes processing device further includes a movable component. The movable component is mounted on the spray pipe 110. The movable component is connected to the spray head 120. The movable component can move under the power provided by the liquid flowing in the spray pipe 110. The movable component can drive the spray head 120 to swing.

[0545] The clothing processing device provided in the embodiment of the present application acts on the movable component through the liquid flowing in the spray pipe 110, so that the movable component moves, and the movable component drives the spray head 120 to swing. The swing of the spray head 120 can expand the spraying area, so that the inner drum 50, the door seal 60 and the door body 30 are effectively rinsed, so as to avoid the foam and other impurities generated by the detergent from remaining on the inner drum 50, the door seal 60 and the door body 30, thereby improving the cleaning effect and ensuring the health of the user.

[0546] In one possible implementation, see Fig.68 As shown, the movable assembly may include a rotating member 160a. The rotating member 160a is rotatably disposed in the spray pipe 110. The movable assembly is configured to move when the liquid in the spray pipe 110 acts on the rotating member 160a.

[0547] The rotating member 160a may include a rotating body 161a and a plurality of blades 162a. The plurality of blades 162a are sequentially arranged on the rotating body 161a along the circumferential direction of the rotating member 160a.

[0548] The rotating body 161a may have a rotating shaft 1611. One end of the rotating shaft 1611 is rotatably connected to the inner wall of the first section 111 of the spray pipe 110, and the other end is rotatably connected to the inner wall of the mounting cover 170. The inner wall of the mounting cover 170 refers to the wall of the mounting cover 170 facing the inside of the spray pipe 110.

[0549] The rotating member 160a can rotate along the axis of the rotating shaft 1611. The rotating shaft 1611 can be placed horizontally. The axis of the rotating shaft 1611 can be parallel to the door body 30. The extending direction of the axis of the rotating shaft 1611 can be perpendicular to the swinging direction of the spray head 120, so that the spray head 120 can swing toward the upper side and the lower side of the clothing processing device 10. The upper side of the clothing processing device 10 refers to the side where the top of the clothing processing device 10 is located when the clothing processing device 10 is in use. The lower side of the clothing processing device 10 refers to the side where the bottom of the clothing processing device 10 is located when the clothing processing device 10 is in use.

[0550] When installing the rotating member 160a, the installation cover 170 is removed from the first section 111 of the spray pipe 110, and then the rotating member 160a is installed into the first section 111 from the installation opening of the first section 111, and finally the installation cover 170 is installed on the first section 111. The rotating member 160a is installed through the installation opening of the first section 111, so that the rotating member 160a is easy to install. In addition, the installation cover 170 can seal the installation opening to prevent the liquid in the spray pipe 110 from leaking from the installation opening.

[0551] In some examples, when the drain pump 70 pumps the mixed liquid in the inner cylinder 50 and the outer cylinder 40 into the circulation pipeline 90, the mixed liquid in the circulation pipeline 90 enters the spray pipe 110, and the liquid in the spray pipe 110 impacts the blades 162a of the rotating member 160a, causing the rotating member 160a to rotate.

[0552] See also Fig.68 As shown, the rotating member 160a can rotate in the counterclockwise direction (ie, -W direction). In other embodiments, the rotating member 160a can also rotate in the clockwise direction (ie, +W direction). The -W direction is the opposite direction of the +W direction.

[0553] See also Fig.68 As shown, the movable assembly may further include a moving rod 190 and a reset member 180 located in the spray pipe 110. The moving rod 190 is fixedly connected to the spray head 120. The reset member 180 is connected between the moving rod 190 and the spray pipe 110. The moving rod 190 drives the spray head 120 to swing under the action of the rotating member 160a and the reset member 180.

[0554] The moving rod 190 can be fixed on the sprinkler head 120 by means of snap connection, thread connection, welding, etc.

[0555] The moving rod 190 can drive the shower head 120 to swing around the axis of the rotating shaft 121a.

[0556] The moving rod 190 may have a portion located in the second section 112 of the spray pipe 110, which portion is fixedly connected to the spray head 120, and another portion extending into the first section 111. The plurality of blades 162a of the rotating member 160a sequentially contact the portion of the moving rod 190 located in the first section 111 during the rotation of the rotating member 160a.

[0557] The reset member 180 may be a tension spring, one end of which is connected to the second section 112 of the spray pipe 110 , and the other end of which is connected to the moving rod 190 .

[0558] Fig.68 The first state of the middle spray head 120 is the state in which the tension spring and the moving rod 190 are both in the initial state and the moving rod 190 is not in contact with the blade 162a during the swinging process of the movable component driving the spray head 120. In some examples, when the drainage pump 70 pumps the mixed liquid in the inner cylinder 50 and the outer cylinder 40 into the circulation pipeline 90, the mixed liquid in the circulation pipeline 90 enters the spray pipe 110. The liquid in the spray pipe 110 impacts the blade 162a of the rotating member 160a to rotate, and the blade 162a has not yet contacted the moving rod 190. The tension spring and the moving rod 190 are both in the initial state.

[0559] Fig.69 The second state of the middle spray head 120 is the state in which the blade 162a of the rotating member 160a drives the moving rod 190 to rotate along the +W direction and the tension spring is stretched during the swinging process of the movable assembly driving the spray head 120. In some examples, when the drainage pump 70 pumps the mixed liquid in the inner cylinder 50 and the outer cylinder 40 into the circulation pipeline 90, the mixed liquid in the circulation pipeline 90 enters the spray pipe 110. The liquid in the spray pipe 110 impacts the blade 162a of the rotating member 160a to rotate. The blade 162a of the rotating member 160a drives the moving rod 190 to rotate along the +W direction, and the tension spring is stretched.

[0560] Fig.70The third state of the middle spray head 120 is the state in which the moving rod 190 rotates to the limit position in the +W direction during the swinging process of the movable component driving the spray head 120. In some examples, when the drainage pump 70 pumps the mixed liquid in the inner cylinder 50 and the outer cylinder 40 into the circulation pipeline 90, the mixed liquid in the circulation pipeline 90 enters the spray pipe 110. The liquid in the spray pipe 110 impacts the blade 162a of the rotating member 160a to rotate. The moving rod 190 rotates to the limit position in the +W direction. As the rotating member 160a continues to rotate, the blade 162a is separated from the moving rod 190. After the moving rod 190 is separated from the blade 162a, the moving rod 190 rotates along the -W direction under the tension of the tension spring and returns to the initial state. It can be understood that the spray head 120 will swing from the third state to the first state. It should be noted that when the moving rod 190 is restored to the initial state, the blade 162a of the rotating member 160a does not contact the moving rod 190. When the moving rod 190 is restored to the initial state, when the next blade 162a of the rotating member 160a moves the moving rod 190 again, the moving rod 190 repeats the above process, so that the moving rod 190 repeatedly swings in the +W direction and the −W direction.

[0561] Fig.68 The position of the middle moving rod 190 is the limit position of the moving rod 190 rotating in the -W direction under the action of the tension spring. Fig.70 The position of the middle moving rod 190 is the limit position of the moving rod 190 rotating in the +W direction under the action of the tension spring and the blade 162a of the rotating member 160a. The moving rod 190 repeatedly swings between the two limit positions, and the moving rod 190 drives the spray head 120 to repeatedly swing, so that the spray head 120 can expand the spraying area, so that the inner cylinder 50, the door seal 60 and the door body 30 are effectively washed.

The other end of the rotating shaft 1611 is passed through and rotatably connected to the mounting cover 170, that is, the rotating shaft 1611 is partially exposed outside the spray pipe 110.

[0569] The rotating shaft 1611 can be placed horizontally. The axis of the rotating shaft 1611 can be parallel to the door body 30. The extending direction of the axis of the rotating shaft 1611 can be perpendicular to the swing direction of the spray head 120, so that the spray head 120 can swing toward the upper side and the lower side of the clothing processing device 10. The upper side of the clothing processing device 10 refers to the side where the top of the clothing processing device 10 is located when the clothing processing device 10 is in use. The lower side of the clothing processing device 10 refers to the side where the bottom of the clothing processing device 10 is located when the clothing processing device 10 is in use.

[0570] The movable assembly may further include a connecting member 163a located outside the spray pipe 110. The connecting member 163a is connected to a portion of the rotating shaft 1611 of the rotating member 160a located outside the spray pipe 110, so that the connecting member 163a rotates with the rotating shaft 1611.

[0571] The connecting member 163a may be a circular connecting plate and may be fixed to the rotating shaft 1611 by means of clamping, threading, welding, etc.

[0572] The connecting member 163a is provided with a connecting shaft 1631. The connecting shaft 1631 is located outside the spray pipe 110. The connecting shaft 1631 rotates around the axis of the rotating shaft 1611.

[0573] In some examples, when the drain pump 70 pumps the mixed liquid in the inner cylinder 50 and the outer cylinder 40 into the circulation pipeline 90, the mixed liquid in the circulation pipeline 90 enters the spray pipe 110. The liquid in the spray pipe 110 impacts the blades 162a of the rotating member 160a, causing the rotating member 160a to rotate in the counterclockwise direction (i.e., the -W direction), thereby causing the rotating shaft 1611 to rotate with the connecting member 163a, and the connecting member 163a rotates with the connecting shaft 1631 around the axis of the rotating shaft 1611.

[0574] See also Fig.72 and Fig.74 As shown, the movable assembly may further include a moving rod 190 located outside the spray pipe 110. One end of the moving rod 190 is fixedly connected to the spray head 120. The other end of the moving rod 190 is movably connected to the connecting member 163a. ​​The moving rod 190 drives the spray head 120 to swing under the action of the connecting member 163a.

[0575] The rotating shaft 121a of the shower head 120 is disposed through and rotatably connected to the second section 112 of the shower pipe 110. In other words, a portion of the rotating shaft 121a is located outside the shower pipe 110, and another portion is outside the shower pipe 110.

[0576] The moving rod 190 can be fixed to the portion of the rotating shaft 121a located outside the spray pipe 110 by means of clamping, threading, welding, etc. It should be noted that in other embodiments, the moving rod 190 can also be provided with a rotating shaft, and the spray head 120 does not need to be provided with a rotating shaft. The rotating shaft of the moving rod 190 is passed through and rotatably connected to the spray pipe 110 and then connected to the spray head 120.

[0577] The moving rod 190 can drive the shower head 120 to swing around the axis of the rotating shaft 121 a through the rotating shaft 121 a.

[0578] The moving rod 190 may be provided with a movable portion 1901. The connecting shaft 1631 may be movably provided in the movable portion 1901.

[0579] The movable portion 1901 may be a movable hole or a movable groove. For example, the movable portion 1901 is an oblong movable hole.

[0580] Fig.72 , Fig.75 , Fig.76 and Fig.77 The dotted line in FIG. 1 is a schematic diagram of the interior of the spray pipe 110 .

[0581] Fig.72The position of the moving rod 190 is the first position. The first position is the position where the connecting shaft 1631 of the connecting member 163a drives the moving rod 190 to start rotating in the -W direction around the axis of the rotating shaft 121a. In some examples, when the drainage pump 70 pumps the mixed liquid in the inner cylinder 50 and the outer cylinder 40 into the circulation pipeline 90, the mixed liquid in the circulation pipeline 90 enters the spray pipe 110. The liquid in the spray pipe 110 impacts the blades 162a of the rotating member 160a. The rotating shaft 1611 rotates counterclockwise around the axis of the rotating shaft 1611 with the connecting member 163a. ​​The connecting shaft 1631 provides a force to rotate in the -W direction to the moving rod 190, and under the action of this force, the moving rod 190 starts to rotate in the -W direction.

[0582] Fig.75 The position of the moving rod 190 is a certain position in the process of the moving rod 190 being driven by the connecting shaft 1631 of the connecting member 163a to rotate around the axis of the rotating shaft 121a in the -W direction. That is, a certain position in the process of the moving rod 190 swinging from the first position to the second position. In some examples, when the connecting shaft 1631 drives the moving rod 190 to rotate in the -W direction, the connecting shaft 1631 moves in the movable part 1901 and abuts against the side wall of the movable part 1901, providing a force to rotate in the -W direction to the moving rod 190. Under the action of this force, the moving rod 190 rotates in the -W direction until it rotates to the second position. At the same time, the moving rod 190 drives the sprinkler head 120 to swing along the -W direction.

[0583] Fig.76 The position of the moving rod 190 is the second position. The second position is the position where the connecting shaft 1631 of the connecting member 163a drives the moving rod 190 to start rotating in the +W direction around the axis of the rotating shaft 121a. In some examples, when the drainage pump 70 pumps the mixed liquid in the inner cylinder 50 and the outer cylinder 40 into the circulation pipeline 90, the mixed liquid in the circulation pipeline 90 enters the spray pipe 110. The liquid in the spray pipe 110 impacts the blades 162a of the rotating member 160a. The rotating shaft 1611 rotates counterclockwise around the axis of the rotating shaft 1611 with the connecting member 163a. ​​The connecting shaft 1631 provides a force to rotate in the +W direction to the moving rod 190, and under the action of this force, the moving rod 190 starts to rotate in the +W direction.

[0584] Fig.77The position of the moving rod 190 is a certain position in the process of the moving rod 190 being driven by the connecting shaft 1631 of the connecting member 163a to rotate around the axis of the rotating shaft 121a in the +W direction. That is, a certain position in the process of the moving rod 190 swinging from the second position to the first position. In some examples, when the connecting shaft 1631 drives the moving rod 190 to rotate in the +W direction, the connecting shaft 1631 moves in the movable part 1901 and abuts against the side wall of the movable part 1901, providing a force to rotate in the +W direction to the moving rod 190. Under the action of this force, the moving rod 190 rotates in the +W direction until it rotates to the first position. At the same time, the moving rod 190 drives the sprinkler head 120 to swing along the +W direction.

[0585] The moving rod 190 repeatedly swings between the first position and the second position. At the same time, the moving rod 190 drives the spray head 120 to repeatedly swing, so that the spray head 120 can expand the spraying area, so that the inner cylinder 50, the door seal 60 and the door body 30 are effectively washed.

[0586] It should be noted that when the moving rod 190 rotates from the first position to the second position and then rotates from the second position to the first position, the connecting shaft 1631 rotates one circle.
