[0092] Some embodiments of the disclosure provide a laundry treating apparatus, which can include a washing machine, a shoe washing machine, or the like, capable of washing laundry. For example, the washing machine can be a drum washing machine or a pulsator washing machine, or the like.

[0093] The laundry treating apparatus 10 in FIG. 1 is a drum washing machine. Hereinafter, the structure of the laundry treating apparatus 10 will be further described in conjunction with FIG. 1, taking the laundry treating apparatus 10 as a drum washing machine as an example.

[0094] Referring to FIG. 1, the laundry treating apparatus 10 can include a cabinet 20. The cabinet 20 is provided with a laundry loading / unloading opening.

[0095] The laundry treating apparatus 10 can include an outer tub 40. The outer tub 40 is provided in the cabinet 20, and a tub opening of the outer tub 40 faces the laundry loading / unloading opening.

[0096] The laundry treating apparatus 10 can include an inner tub 50. The inner tub 50 is disposed to rotate within the outer tub 40, and a tub opening of the inner tub 50 faces the laundry loading / unloading port. The inner tub 50 has a second cavity. During washing of laundry, the inner tub 50 can rotate relative to the outer tub 40 to wash laundry in the second cavity. The second cavity is in communication with the first cavity of the outer tub 40. For example, a plurality of through-holes can be formed in the inner tub 50, and the plurality of through-holes can be uniformly distributed on a tub wall of the inner tub 50. Water in the second cavity can flow into the outer tub 40 through the through-holes in the tub wall of the inner tub 50, and the water can be drained from the outer tub 40 after washing is completed.

[0097] Referring to FIG. 1, the laundry treating apparatus 10 can further include a door 30. The door 30 is coupled to the housing 20 to cover the laundry loading / unloading port. For example, the door 30 can be disposed at a position of the laundry loading / unloading port and coupled to the housing 20 to rotate, so that the door 30 can cover the laundry loading / unloading port. Thus, a user can conveniently open the door 30 to load laundry into the inner tub 50 through the laundry loading / unloading port and wash the laundry by the laundry treating apparatus 10.

[0098] Referring to FIG. 1, the laundry treating apparatus 10 can further include a door seal 60. The door seal 60 is disposed between the tub opening of the outer tub 40 and the door 30 to seal a gap between the door 30 and the tub opening of the outer tub 40. For example, the door 30 can be a glass door 30 so that a user can observe a state of laundry in the inner tub 50 through the door 30.

[0099] The laundry treating apparatus 10 can further include a water inlet pipe. A portion of the water inlet pipe can be disposed in the housing 20, and another portion of the water inlet pipe can be disposed outside the housing 20 so as to be connected to an external water source such as a faucet. The water inlet pipe is configured to supply water to the inner tub 50, and water flowing through the water inlet pipe can carry detergent into the inner tub 50 so that the laundry treating apparatus 10 can wash laundry in cooperation with water and the detergent.

[0100] Referring to FIG. 1, the laundry treating apparatus 10 can further include a drain pipe 80. A portion of the drain pipe 80 can be disposed in the housing 20, and another portion of the drain pipe 80 can be disposed outside the housing 20 so as to drain liquid outside the housing 20.

[0101] The laundry treating apparatus 10 can further include a drain pump 70. The drain pump 70 is disposed in the housing 20 and can be in communication with the outer tub 40 so that the drain pump 70 can pump liquid in the outer tub 40 into the drain pipe 80. For example, a water inlet end of the drain pump 70 can be in communication with a drain port of the outer tub 40 to achieve communication between the drain pump 70 and the outer tub 40.

[0102] The laundry treatment apparatus 10 has a laundry treatment program. For example, the laundry treatment program includes a washing program, a rinsing degree, etc. At the time of the laundry treatment program, the drain pump 70 is configured to pump the liquid in the inner tub 50 and the outer tub 40 into the drain pipe 80 so as to drain the liquid to the outside of the housing 20 through the drain pipe 80, thereby implementing an external drain function of the laundry treatment apparatus 10. For example, when the laundry treatment program is the washing program, the liquid in the inner tub 50 and the outer tub 40 can be a liquid formed by mixing water and a detergent. When the laundry treatment program is the rinsing degree, the liquid in the inner tub 50 and the outer tub 40 can be water or a mixed liquid formed by mixing water and a whitening agent, etc.

[0103] It should be noted that, when the laundry treatment apparatus 10 is operated, the inner tub 50 can rotate, and the liquid in the inner tub 50 can enter the outer tub 40 through the through holes on the tub wall of the inner tub 50 so as to enter the drain pump 70 through the drain port of the outer tub 40, so that the drain pump 70 can pump the liquid in the inner tub 50 and the outer tub 40 into the drain pipe 80.

[0104] In some embodiments, the laundry treatment apparatus 10 can further include a heater, by which the water in the inner tub 50 can be heated, so as to implement a heated washing function of the laundry treatment apparatus 10 on the laundry, and improve the washing effect of the laundry treatment apparatus 10 on the laundry.

[0105] However, some laundry treatment apparatuses in the related art have a long washing time and a poor washing effect in the case of not heated washing.

[0106] Since the drain pump of these laundry treatment apparatuses is a conventional one-way rotation drain pump, the drain pump can only rotate in one direction, and such a drain pump cannot simultaneously satisfy the external drain function and the internal circulation spraying function of the laundry treatment apparatus. If a two-way drain pump is used, although the external drain function and the internal circulation spraying function of the laundry treatment apparatus can be satisfied by rotating the two-way drain pump in two different directions (such as forward rotation or reverse rotation), compared with the one-way rotation drain pump, the two-way drain pump has a higher manufacturing cost, which will increase the manufacturing cost of the laundry treatment apparatus.

[0107] Therefore, another laundry treatment apparatus in the related art is further provided with a circulation pipeline and a spraying head. When the laundry treatment apparatus operates the laundry treatment program and the laundry treatment program is the washing program, the circulation pipeline can introduce the liquid drained from the inner tub 50 and the outer tub 40 into the spraying head, and the liquid can be sprayed into the inner tub 50 by the spraying head, and the laundry can be sprayed with the liquid so that the laundry can be washed, thereby implementing the internal circulation spraying function of the laundry treatment apparatus. In this way, the washing effect and the washing effect can be improved, and it is beneficial to save time and water.

[0108] Similarly, when the laundry treatment apparatus operates a laundry treatment program, and the laundry treatment program is a rinsing program, the internal circulation spraying function of the laundry treatment apparatus can also be realized through the circulation pipeline to improve the rinsing effect, thereby improving the cleaning effect, and it is beneficial to save time and water.

[0109] In this case, the other laundry treatment apparatuses in the related art are additionally provided with a circulation pump, and the circulation pump can pump the liquid in the inner tub 50 and the outer tub 40 into the circulation pipeline, thereby realizing the above-mentioned function of the circulation pipeline.

[0110] However, the introduction of the circulation pump causes the laundry treatment apparatus to have both the drain pump 70 and the circulation pump, so that although the manufacturing cost of the laundry treatment apparatus can be slightly saved compared with the bidirectional drain pump, the manufacturing cost is still higher compared with the laundry treatment apparatus provided with only the unidirectional rotation drain pump.

[0111] To solve the above technical problems, some embodiments of the present disclosure provide a laundry treatment apparatus 10, which connects the drain pump, the drain pipe, and the circulation pipeline through a communication device respectively, and controls the communication device through a control device to realize the switching of the water path between the drain pump, the drain pipe, and the circulation pipeline, so that the external drain function and the internal circulation spraying function of the laundry treatment apparatus 10 can be realized while reducing the manufacturing cost of the laundry treatment apparatus 10.

[0112] Referring to FIGS. 1 to 3, the laundry treatment apparatus 10 provided by some embodiments of the present disclosure further includes a communication device 200 and a control device 300. The communication device 200 has a mounting seat 210 and a blocking piece 230, and the mounting seat 210 has three ports. The three ports can be connected to 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, respectively. The blocking piece 230 can move in the mounting seat 210 under the control of the control device 300 to connect the water outlet 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 through the cooperation of the drain pump 70, the communication device 200, and the control device 300, the external drain function and the internal circulation spraying function of the laundry treatment apparatus 10 can be met. At the same time, compared with the laundry treatment apparatuses in the related art mentioned above which are additionally provided with a circulation pump, or the laundry treatment apparatuses provided with a bidirectional drain pump, the laundry treatment apparatus 10 provided by some embodiments of the present disclosure can also reduce the manufacturing cost of the laundry treatment apparatus 10.

[0113] This will be further described below in combination with the drawings and some embodiments.

[0114] Referring to FIG. 4, in some embodiments, the laundry treatment apparatus 10 can include the communication device 200.

[0115] The communication device 200 can include a mounting seat 210. The mounting seat 210 has a third cavity 211 and three ports communicating with the third cavity 211. For the convenience of description, the three ports are defined as a first port 212 (a first communication port), a second port 213 (a second communication port) and a third port 214 (a third communication port) respectively.

[0116] In the first direction, the first port 212 and the second port 213 can be spaced apart on the circumferential side wall of the mounting seat 210, and the third port 214 can be arranged at the end of the mounting seat 210. The first direction is parallel to the length direction of the mounting seat 210, for example, the first direction includes the X direction shown in FIG. 4, and the direction opposite to the X direction.

[0117] The first port 212 can communicate with the water outlet end of the drain pump 70. The second port 213 can communicate with the water inlet end of the circulation pipeline 90. The third port 214 can communicate with the water inlet end of the drain pipeline 80. The communication between 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 inlet end of the drain pipeline 80 is realized through the three ports.

[0118] The communication device 200 can further include a blocking member 230. The communication device 200 can further include a first moving member 220. The blocking member 230 can be arranged outside the first moving member 220, and the blocking member 230 and the first moving member 220 are arranged in the third cavity 211 to realize the installation of the blocking member 230 and the first moving member 220 in the mounting seat 210. For example, in the first direction, the blocking member 230 is opposite to the third port 214.

[0119] It should be noted that the "A is opposite to B in a certain direction" mentioned in some embodiments of the present disclosure can be understood as that A and B are arranged opposite to each other in a certain direction. For example, the arrangement of A opposite to B does not mean that the center of A and the center of B are absolutely opposite to each other, and under the condition of permission, the center of A and the center of B can also have a slight positional deviation in the first direction. For example, "the blocking member 230 is opposite to the third port 214 in the first direction" can be understood as that the center of the blocking member 230 and the center of the third port 214 can be arranged opposite to each other in the first direction, or the center of the blocking member 230 and the center of the third port 214 can also have a slight positional deviation in the first direction without affecting the sealing of the blocking member 230 to the third port 214 and other ports. In the following, similar descriptions can be understood in this way.

[0120] Referring to FIG. 4, in some embodiments, the laundry treating apparatus 10 can further include a control device 300. The control device 300 can include a control member 310 connected with the first moving member 220. The control member 310 is configured to control the first moving member 220 to move toward the third port 214 or away from the third port 214, so as to drive the blocking member 230 to move synchronously in the third cavity 211, and thus to communicate the first port 212 with the second port 213 or to communicate the first port 212 with the third port 214.

[0121] In this way, the first moving member 220 can drive the blocking member 230 to move in the third cavity 211 under the control of the control member 310, so as to selectively communicate the first port 212 with the second port 213 or the third port 214, and thus to communicate the water outlet of the drainage pump 70 with the water inlet of the circulation pipeline 90 or to communicate the water outlet of the drainage pump 70 with the water inlet of the drainage pipe 80.

[0122] Referring to FIG. 4, when the laundry treating apparatus 10 is running a laundry treating program, the control member 310 can control the first moving member 220 to control the blocking member 230 to communicate the water outlet of the drainage pump 70 with the water inlet of the circulation pipeline 90. At this time, the drainage 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 function of inner-circulation spraying of the laundry treating apparatus 10, and thus to improve the washing effect or the rinsing effect, and further to improve the washing effect.

[0123] Referring to FIG. 5, when the laundry treating program of the laundry treating apparatus 10 ends, the control member 310 can control the first moving member 220 to control the blocking member 230 to communicate the water outlet of the drainage pump 70 with the water inlet of the drainage pipe 80. At this time, the drainage pump 70 can pump the liquid in the inner drum 50 and the outer drum 40 into the drainage pipe 80, so as to realize the function of external drainage of the laundry treating apparatus 10.

[0124] Therefore, the laundry treating apparatus 10 of some embodiments of the present disclosure can realize the functions of external drainage and inner-circulation spraying of the laundry treating apparatus 10 by the communication device 200, the control device 300 and the drainage pump 70, and thus to improve the washing effect of the laundry treating apparatus 10.

[0125] In addition, the laundry treating apparatus 10 of some embodiments of the present disclosure does not need to be provided with a drainage pump 70 having a bidirectional rotation function. The drainage pump 70 in the laundry treating apparatus 10 can be a unidirectional rotation drainage pump, and thus to reduce the manufacturing cost of the laundry treating apparatus 10.

[0126] Meanwhile, the communication device 200 and the control device 300 have simple structures, and thus to reduce the manufacturing cost compared with the laundry treating apparatus having a circulation pump in the related art.

[0127] And, through the limitation of the positions of the first port 212 and the second port 213 and the third port 214, through the movement of the first moving member 220 in the first direction, the first port 212 can selectively communicate with the second port 213 or the third port 214, so that the movement of the first moving member 220 can be simplified, and the plugging effect of the plugging member 230 can be improved.

[0128] It should be understood that when the laundry treatment program is a washing program, some embodiments of the disclosure can improve the washing effect of the laundry treatment apparatus 10. When the laundry treatment program is a rinsing program, some embodiments of the disclosure can improve the rinsing effect of the laundry treatment apparatus 10.

[0129] Hereinafter, the structure of the laundry treatment apparatus 10 will be further described with the laundry treatment program being a washing program as an example.

[0130] Referring to FIG. 1, in some embodiments, the laundry treatment apparatus 10 can further include a spray head 120. The spray head 120 can communicate with the water outlet end of the circulation line 90, and the spray head 120 can face the inner tub 50, so that when the liquid pump 70 pumps the liquid into the circulation line 90, the liquid in the circulation line 90 can be sprayed to the inner tub 50 through the spray head 120, thereby spraying the liquid to the laundry in the inner tub 50, achieving the inner circulation spraying function of the laundry treatment apparatus 10, improving the washing effect and cleaning effect, and being beneficial to saving time and water.

[0131] And, the liquid sprayed by the spray head 120 to the inner tub 50 can also wash the inner tub 50, the door seal 60, the door body 30, etc., so as to avoid the impurities such as foam generated by the detergent remaining in the inner tub 50 and the door body 30, which is beneficial to improving the cleaning effect of the laundry.

[0132] 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, so as to achieve the installation of the spray head 120 in the housing 20. For example, when the spray head 120 is installed on the door seal 60, the spray head 120 can rotate, swing, etc. relative to the door seal 60, so as to expand the spraying area of the spray head 120. Alternatively, by changing the structure of the spray head 120 (which will be described in detail later), when the spray head 120 is fixed (i.e. does not rotate or swing) relative to the door seal 60, the spraying area of the spray head 120 can also be expanded.

[0133] The liquid pump 70, the communication device 200, the control device 300 and the circulation line 90 can be respectively arranged in the housing 20, so as to achieve the communication of the three ports of the mounting seat 210 with the water outlet end of the liquid pump 70, the water inlet end of the circulation line 90 and the water inlet end of the drain pipe 80, and at the same time, the connection of the control member 310 with the first moving member 220, so as to control the movement of the first moving member 220 through the control member 310.

[0134] Referring to FIG. 4, when the communication device 200 and the control device 300 are disposed in the housing 20, the communication device 200 can be installed at the bottom of the housing 20. For example, 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 (e.g., the ground) of the laundry treating apparatus 10, so that, when the communication device 200 is installed at the bottom of the housing 20, the installation space of the communication device 200 in the housing 20 in the height direction of the laundry treating apparatus 10 can be compressed, so as to increase the processing amount of the laundry treating apparatus 10 on the laundry while the height of the housing 20 is unchanged.

[0135] It is to be noted that the height direction of the laundry treating apparatus 10 is perpendicular to the first direction. When the laundry treating apparatus 10 is disposed on the placement platform, the height direction of the laundry treating apparatus 10 can be understood as the direction perpendicular to the plane on which the placement platform is located.

[0136] Referring to FIG. 4, when the laundry treating apparatus 10 is operating the laundry treating program, the blocking member 230 can be located at the third port 214, and the blocking member 230 can block the third port 214, so as to communicate the first port 212 and the second port 213.

[0137] In this way, when the laundry treating apparatus 10 is operating the laundry treating program, the first port 212 and the second port 213 are communicated, and since the third port 214 is blocked by the blocking member 230, in this case, the liquid in the inner tub 50 and the outer tub 40 can only be pumped into the circulation pipeline 90 by the drainage pump 70, and cannot enter the third port 214.

[0138] Referring to FIG. 5, when the laundry treating apparatus 10 is performing the external drainage, in the first direction, the blocking member 230 can be located between the first port 212 and the second port 213, and the blocking member 230 can abut against the inner wall of the mounting seat 210, so as to communicate the first port 212 and the third port 214.

[0139] In this way, when the laundry treating apparatus 10 is performing the external drainage, the first port 212 and the third port 214 are communicated, and since the second port 213 is blocked by the blocking member 230, at this time, the liquid in the inner tub 50 and the outer tub 40 can only be pumped into the drainage pipe 80 by the drainage pump 70, and cannot enter the second port 213, so as to affect the external drainage effect of the laundry treating apparatus 10.

[0140] And, since the blocking member 230 has moved to between the first port 212 and the second port 213, the third port 214 is in an open state, in which case the first port 212 can communicate with the third port 214, and the external water discharge function of the laundry treatment apparatus 10 can be ensured. Also, the first port 212 and the third port 214 can be ensured to be unblocked by the blocking member 230 and to be in an open state. In this way, it is possible to prevent lint in the liquid from blocking the first port 212 and the third port 214 when the liquid flows from the first port 212 to the third port 214, to ensure that the liquid of the drain pump 70 can be discharged to the outside of the housing 20 via the drain hose 80.

[0141] It can be understood that, in the case where the laundry treatment apparatus 10 (a drum-type washing machine) adopts the upper water discharge, the liquid in the drain hose 80 can not be completely discharged and can remain in the drain hose 80, and the liquid (hereinafter referred to as residual water) remaining in the drain hose 80 can flow back to the outer tub 40 or even the inner tub 50 via the drain hose 80. When the residual water that flows back remains in the outer tub 40 for a long time, it can cause odor in the laundry treatment apparatus 10 and can contaminate the liquid in the inner tub 50 in the next laundry treatment process, affecting the washing effect of the laundry treatment apparatus 10.

[0142] It should be noted that the upper water discharge of the laundry treatment apparatus 10 means that the water discharge end of the drain hose 80 is located at one side of the top of the housing 20, so that the drain hose 80 discharges water from one side of the top of the housing 20.

[0143] In some embodiments, referring to FIG. 6, after the laundry treatment apparatus 10 performs a laundry treatment process or after the laundry treatment process ends, the blocking member 230 is located at the third port 214, and the blocking member 230 can block the third port 214 to communicate the first port 212 and the second port 213. After the laundry treatment process of the laundry treatment apparatus 10 ends, since the third port 214 is blocked by the blocking member 230, the backflow passage of the residual water in the drain hose 80 can be blocked by the blocking member 230, to avoid the residual water flowing back to the outer tub 40 or even the inner tub 50, causing odor in the laundry treatment apparatus 10, and thus ensuring the washing effect of the laundry treatment apparatus 10.

[0144] Referring to FIGS. 4 to 6, in some embodiments, the laundry treatment apparatus 10 can further include a one-way valve 400. The one-way valve 400 can be provided at the water inlet end of the drain pump 70 or the water discharge port of the outer tub 40, and is configured to be able to conduct the water discharge port of the outer tub 40 and the water inlet end of the drain pump 70 under the pressure of the liquid in the outer tub 40.

[0145] When the laundry treating apparatus 10 is operating a cycle spray function or an external drainage function, the one-way valve 400 is opened under the pressure of the liquid in the outer tub 40, in which case the drainage port of the outer tub 40 is communicated with the water inlet end of the drainage pump 70, so that the internal cycle spray function or the external drainage function of the laundry treating apparatus 10 can be achieved.

[0146] Referring to FIG. 6, if the blocking effect of the blocking member 230 on the third port 214 is reduced after the laundry treating apparatus 10 is used for a long time, causing the liquid in the drain pipe 80 to flow back to the side of the outer tub 40, when the liquid reaches the one-way valve 400, the one-way valve 400 is in a closed state and cannot be opened because the one-way valve 400 can only be communicated in one direction, so that the backflow of residual water can be further blocked outside the outer tub 40, achieving secondary blocking of the residual water.

[0147] Therefore, some embodiments of the present disclosure can achieve double blocking of residual water by the blocking member 230 and the one-way valve 400, avoiding the backflow of residual water into the outer tub 40 or even the inner tub 50, causing odor in the laundry treating apparatus 10, and ensuring the washing effect of the laundry treating apparatus 10.

[0148] Referring to FIG. 6, in some embodiments, the one-way valve 400 can be a rubber one-way valve, and the first end of the rubber one-way valve can be a circular ring opening structure, which is always open. The second end of the rubber one-way valve can be a flat closed state, for example, the annular inner wall of the one-way valve 400 is contracted and adhered. When installed, one end of the circular ring opening can be directed towards the outer tub 40, and the closed end can be directed towards one end of the drainage pump 70.

[0149] Referring to FIG. 5, during use, the liquid in the outer tub 40 can enter the one-way valve 400 from one end of the opening. The closed port 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, and the mixed liquid in the outer tub 40 can enter the drainage pump 70.

[0150] Referring to FIG. 6, when the drainage is completed, the mixed liquid in the outer tub 40 is drained, and the one-way valve 400 towards one end of the drainage pump 70 will return to a closed state, thereby avoiding the backflow of water outside the outer tub 40 into the outer tub 40 through the one-way valve 400.

[0151] The structure of the various communication devices 200 and the cooperation with the control device 300 of some embodiments of the present disclosure will be further described below in conjunction with the drawings and some embodiments.

[0152] Referring to the drawings below, first, the structure of the first communication device 200 and the cooperation with the control device 300 will be further described.

[0153] Referring to FIG. 6, in the first communication device 200, the first moving member 220 can be configured to move relative to the control device 300 in the first direction under the traction of the control member 310, so as to drive the blocking member 230 to move synchronously in the first direction, so that the blocking member 230 can be located at the third port 214, or between the first port 212 and the second port 213, so as to selectively communicate the first port 212 with the second port 213 or the third port 214.

[0154] For example, for the communication device 200, the first state is that the first port 212 of the communication device 200 is communicated with the second port 213, and the third port 214 is blocked, in which case the laundry treating apparatus 10 can implement the internal circulation spraying function.

[0155] For the communication device 200, the second state is that the first port 212 of the communication device 200 is communicated with the third port 214, and the blocking member 230 blocks between the first port 212 and the second port 213, in which case the laundry treating apparatus 10 can implement the external drainage function.

[0156] Referring to FIG. 7 and FIG. 8, one end of the blocking member 230 adjacent to the third port 214 is a first end portion 231 (blocking end portion), which is opposite to the third port 214 in the first direction. When the first moving member 220 moves relative to the control device 300 in the first direction under the traction of the control member 310, the first end portion 231 can be driven to move synchronously in the first direction within the third cavity 211, so as to communicate the first port 212 with the second port 213, or communicate the first port 212 with the third port 214, thereby implementing the internal circulation spraying function or the external drainage function of the laundry treating apparatus 10.

[0157] As shown in FIG. 7, when the first end portion 231 moves to the third port 214 in the first direction, the first end portion 231 can block the third port 214, so as to communicate the first port 212 with the second 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 implementing the internal circulation spraying function of the laundry treating apparatus 10.

[0158] As shown in FIG. 8, when the first end portion 231 moves to between the first port 212 and the second port 213 in the first direction, the first end portion 231 abuts against the inner wall of the mounting seat 210, so as to communicate the first port 212 with the third port 214, so that the drainage pump 70 can pump the liquid in the inner drum 50 and the outer drum 40 into the drainage pipeline 80, thereby implementing the external drainage function of the laundry treating apparatus 10.

[0159] Referring to FIGS. 9 and 10, in some embodiments, the blocking member 230 further comprises a first blocking portion 2311 and a second blocking portion 2312. For example, the first blocking portion 2311 can be located at the circumference of the first end portion 231, and the second blocking portion 2312 can be located at the end face of the first end portion 231 close to the third port 214.

[0160] As shown in FIG. 9, when the first end portion 231 moves in the first direction to the third port 214, the first blocking portion 2311 and the second blocking portion 2312 are located at the circumferential side of the third port 214 and abut against the inner wall of the mounting seat 210, respectively. In this way, the first end portion 231 can achieve double blocking of the third port 214 through the first blocking portion 2311 and the second blocking portion 2312, thereby enhancing the blocking effect of the first end portion 231 on the third port 214, avoiding backflow of residual water to the outer cylinder 40, and ensuring the internal circulation spraying effect of the laundry treatment apparatus 10.

[0161] For example, the first blocking portion 2311 can abut against the end portion inner wall of the mounting seat 210 provided with the third port 214, and the second blocking portion 2312 can abut against the circumferential inner wall of the mounting seat 210 adjacent to the third port 214. For example, the inner wall of the mounting seat 210 includes the end portion inner wall and the circumferential inner wall.

[0162] As shown in FIG. 10, when the first end portion 231 moves in the first direction to between the first port 212 and the second port 213, the first blocking portion 2311 can abut against the circumferential inner wall of the mounting seat 210, so that the first blocking portion 2311 can block between the first port 212 and the second port 213 to avoid the first port 212 and the second port 213 being in communication, and ensure that the first port 212 and the third port 214 are not blocked by the blocking member 230 and are in an open state, thereby preventing lint in the liquid from blocking the first port 212 and the third port 214, and ensuring that the liquid of the drainage pump 70 can be discharged to the outside of the housing 20 through the drain pipe 80.

[0163] It should be noted that when the first blocking portion 2311 blocks between the first port 212 and the second port 213, the first blocking portion 2311 abuts against the circumferential inner wall of the mounting seat 210, and is not limited to being located adjacent to the first port 212 (as shown in FIGS. 8 and 10). For example, the first blocking portion 2311 can also be located adjacent to the second port 213.

[0164] Referring to FIG. 10, in some embodiments, the first sealing part 2311 and the second sealing part 2312 can have a ring shape, so that the first sealing part 2311 and the second sealing part 2312 can abut against the inner wall of the mounting seat 210 in the circumferential direction of the first end part 231, thereby enhancing the sealing effect of the first sealing part 2311 and the second sealing part 2312 on the third port 214 and the blocking effect of the first sealing part 2311 between the first port 212 and the second port 213.

[0165] The sealing member 230 includes at least one first sealing part 2311. In some embodiments, the sealing member 230 includes one first sealing part 2311. In some embodiments, the sealing member 230 includes a plurality of first sealing parts 2311. When the sealing member 230 includes a plurality of first sealing parts 2311, the plurality of first sealing parts 2311 can be spaced apart in the circumferential direction of the first end part 231 in the first direction, thereby enhancing the sealing effect of the first sealing part 2311 on the third port 214 and the blocking effect of the first sealing part 2311 between the first port 212 and the second port 213.

[0166] As shown in FIG. 9, in some embodiments, the sealing member 230 further includes a third sealing part 2313. The third sealing part 2313 is arranged on the end face of the first end part 231. The third sealing part 2313 has a shape matching that of the third port 214. When the first end part 231 moves to the third port 214 in the first direction, at least part of the third sealing part 2313 is located in the third port 214, thereby sealing the third port 214. In addition to the first sealing part 2311 and the second sealing part 2312, the third sealing part 2313 further seals the inside of the third port 214, thereby further enhancing the sealing effect of the first end part 231 on the third port 214.

[0167] It should be noted that the phrase "the shape of A matches the shape of B" mentioned in some embodiments of the present disclosure can be understood as the shape of A being the same as or similar to the shape of B. For example, the phrase "the shape of the third sealing part 2313 matches the shape of the third port 214" can be understood as the shape of the third sealing part 2313 being the same as or similar to the shape of the third port 214. The same understanding can be applied to similar descriptions below.

[0168] Referring to FIG. 7, in the first direction, the sealing member 230 further includes a seventh segment 233 (middle segment) located on the side of the first end part 231 facing the control device 300. In some embodiments, the outer diameter of the seventh segment 233 can be smaller than the outer diameter of the first end part 231. In this way, while ensuring the sealing effect of the first end part 231 on the third port 214, the sealing member 230 can have a retracted structure at the position of the seventh segment 233 in the first direction.

[0169] By the retracted structure of the blocking member 230 at the position of the seventh segment 233, the blocking member 230 can reduce the obstruction to the first port 212 when the first port 212 is in communication with the second port 213, so as to make the first port 212 in an open state. In this way, when the liquid flows from the first port 212 to the second port 213, the lint in the liquid is less likely to block the first port 212 and the second port 213, so as to ensure that the liquid of the drainage pump 70 can be circulated to the inner drum 50 through the circulation pipeline 90.

[0170] In some embodiments, the first end portion 231 can be a flexible structure having a cavity, and the end portion of the first moving member 220 can be arranged in the cavity of the first end portion 231, so that the first moving member 220 can be arranged in the first end portion 231 to drive the first end portion 231 to move, so as to selectively communicate the first port 212 with the second port 213 or the third port 214. For example, the flexible structure includes a structure made of a material such as rubber, which has ductility and elasticity.

[0171] In addition, the flexible structure of the first end portion 231 can be deformed. In this way, when the first blocking portion 2311 and the second blocking portion 2312 respectively abut against the inner wall of the mounting seat 210 during the movement of the first end portion 231 in the mounting seat 210, the first blocking portion 2311 and the second blocking portion 2312 can be deformed to respectively form an interference fit 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 with the inner wall of the mounting seat 210.

[0172] In addition, the first blocking portion 2311 and the second blocking portion 2312 can be deformed respectively, so as to facilitate the movement of the blocking member 230 in the direction close to the control device 300 under the driving of the first moving member 220.

[0173] In addition, when the third blocking portion 2313 is located in the third port 214, the third blocking portion 2313 can also form an interference fit with the third port 214 of the mounting seat 210, so as to achieve the abutment of the third blocking portion 2313 with the inner wall of the mounting seat 210, and enhance the blocking effect of the third blocking portion 2313 on the third port 214.

[0174] In some embodiments, the first blocking portion 2311, the second blocking portion 2312 and the third blocking portion 2313 are flexible structures, and the remaining positions of the first end portion 231 are non-flexible structures.

[0175] Hereinafter, the structure of the first communication device 200 will be further described by taking the flexible structure of the first end portion 231 as an example.

[0176] Referring to FIG. 10, in some embodiments, the end of the first moving member 220 can further have a fourth supporting portion 221. The fourth supporting portion 221 has a shape matching the cavity shape of the first end portion 231. The fourth supporting portion 221 is supported inside the cavity of the first end portion 231 to ensure the stability of the structure and shape of the first end portion 231, thereby avoiding the failure of the blocking effect of the first end portion 231 after the laundry treatment apparatus 10 is used for a long time. Also, it can avoid excessive deformation of any one of the first blocking portion 2311, the second blocking portion 2312, and the third blocking portion 2313 toward the inside of the cavity when the any one of the first blocking portion 2311, the second blocking portion 2312, and the third blocking portion 2313 abuts against the inner wall of the mounting seat 210, affecting the blocking effect of the first end portion 231 on the third port 214 and the blocking effect of the first end portion 231 on the first port 212 and the second port 213.

[0177] Referring to FIG. 8, in some embodiments, the communication device 200 can further include an end cover 250. The end cover 250 is provided at the end of the mounting seat 210 away from the third port 214 to seal the third cavity 211, and enable the liquid pumped into the third cavity 211 by the drainage pump 70 to accurately flow toward the second port 213 or the third port 214, thereby ensuring the realization of the inner circulation spraying and outer drainage functions of the laundry treatment apparatus 10.

[0178] In some embodiments, the end cover 250 can be integrally connected with the control device 300.

[0179] Referring to FIG. 8, the first moving member 220 can be provided through the end cover 250 and connected with the control member 310, so as to control the movement of the first moving member 220 through the control member 310.

[0180] Referring to FIG. 8, the blocking member 230 is provided with a second end portion 232 (fixed end portion) adjacent to one end of the end cover 250. The second end portion 232 can be installed on the side of the end cover 250 facing the third cavity 211, so that the blocking member 230 can be installed in the third cavity 211 through the end cover 250.

[0181] In some embodiments, the side of the end cover 250 facing the third cavity 211 can have a supporting table which can be supported in the second end portion 232, and the end of the mounting seat 210 adjacent to the control device 300 can be pressed on the second end portion 232 and installed in the end cover 250 to realize the installation of the second end portion 232 on the end cover 250.

[0182] Referring to FIG. 8, in some embodiments, the communication device 200 can further include a first reset member 240 (elastic member). The first reset member 240 can be sleeved on the outer periphery of the first moving member 220 and located between the first moving member 220 and the blocking member 230. A first end of the first reset member 240 can abut against the first moving member 220, and the other end can abut against the side of the end cover 250 facing the third cavity 211. For example, the first reset member 240 abuts between the first moving member 220 and the end cover 250 to achieve installation of the first reset member 240 in the third cavity 211.

[0183] Since the first reset member 240 abuts between the first moving member 220 and the end cover 250, when the first moving member 220 moves toward the control member 310 under the traction force of the control member 310 and drives the first end portion 231 to move from the third port 214 to between the first port 212 and the second port 213 in the first direction, the first reset member 240 is compressed.

[0184] When the first end portion 231 moves to between the first port 212 and the second port 213 in the first direction, and the control member 310 releases the first moving member 220, the first reset member 240 releases the elastic potential energy and elongates, and can exert a force on the first moving member 220 to move the first moving member 220 toward the third port 214 under the action of the force, and drive the first end portion 231 to move to the third port 214 at the same time, so that the first moving member 220 and the first end portion 231 are automatically reset.

[0185] Referring to FIG. 8, in some embodiments, the second end portion 232 is configured as a telescopic structure capable of telescoping in the first direction. For example, the second end portion 232 can be a bellows or other hollow structure capable of telescoping. In this way, when the first reset member 240 telescopes, the second end portion 232 can also telescope synchronously to ensure that the first end portion 231 can move in the first direction toward or away from the third port 214 under the driving of the first moving member 220.

[0186] Referring to FIG. 8, in the case where the first communication device 200 is used in the clothes treatment apparatus 10, 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, and the first moving member 220 is pulled by the steel wire rope to control the movement of the first moving member 220.

[0187] When the laundry treating apparatus 10 is performing the external drainage, the puller can pull the pull cord to pull the first moving member 220 toward the control device 300 through the pull cord, and then pull the first end portion 231 toward the control device 300, so that the first end portion 231 can be moved between the first port 212 and the second port 213 to block the first port 212 and the second port 213 and to connect the first port 212 and the third port 214. In this case, the second end portion 232 and the first reset member 240 are compressed.

[0188] After the external drainage is completed, the puller can release the pull cord so that the pull cord is in a released state. At this time, the pull cord no longer has a pulling force on the first moving member 220. The first moving member 220 will move toward the third port 214 under the action of the rebounding force, and the first end portion 231 will be moved to the third port 214 at the same time, so that the first moving member 220 and the first end portion 231 are reset. In this case, the first end portion 231 blocks the third port 214, which can prevent the residual water in the drain pipe 80 from flowing back.

[0189] It should be noted that the laundry treating apparatus 10 shown in FIGS. 11 to 13 adopts the second connecting device 200 provided by some embodiments of the present disclosure.

[0190] Referring to FIGS. 11 to 13, in another laundry treating apparatus 10 provided by some embodiments of the present disclosure, the control member 310 of the control device 300 can control the first moving member 220 in the second connecting device 200 to move to drive the blocking member 230 to selectively connect the first port 212 with the second port 213 or the third port 214, so as to realize the cycle spraying function or the external drainage function of the laundry treating apparatus 10.

[0191] The difference from the first connecting device 200 is that the first moving member 220 is configured to rotate around the control member 310 and move relative to the control device 300 in the first direction when the control member 310 rotates, so as to drive the blocking member 230 to rotate and move at the same time. In this way, the first port 212 can be selectively connected with the second port 213 or the third port 214 through the movement of the blocking member 230.

[0192] The structure of the second connecting device 200 and the cooperation with the control device 300 will be further described below in combination with the drawings and embodiments.

[0193] Referring to FIGS. 14 to 16, in some embodiments, the first moving member 220 can be sleeved outside the control member 310 and threadedly connected with the control member 310. When the control member 310 rotates, the first moving member 220 rotates around the control member 310, and in the process of rotation, the first moving member 220 can also move linearly along the axial direction of the control member 310, thereby driving the blocking member 230 to rotate and move simultaneously. In this way, by moving the blocking member 230, the first port 212 can be selectively communicated with the second port 213 or the third port 214. Moreover, by changing the rotating direction of the control member 310, the automatic reset of the first moving member 220 and the blocking member 230 can be realized, without the need to set the first reset member 240.

[0194] For example, the axial direction of the control member 310 is parallel to the first direction, so as to ensure that in the process of rotation of the first moving member 220, the first moving member 220 can move along the first direction towards the third port 214 or away from the third port 214.

[0195] Referring to FIG. 15, one end of the control member 310 towards the third port 214 can be referred to as the end of the control member 310. The end of the control member 310 is provided with a toothed external thread structure. The inner wall of the first moving member 220 can be provided with an internal thread structure matched with the control member 310. When the first moving member 220 is sleeved on the end of the control member 310, the first moving member 220 is threadedly connected with the control member 310.

[0196] The control device 300 can be an electric motor, and the control member 310 can be a rotating shaft of the electric motor.

[0197] When the electric motor is started during the external drainage of the laundry treatment apparatus 10, the rotating shaft rotates in a first preset direction, so that in the process of rotation of the first moving member 220 around the rotating shaft, the first moving member 220 can move along the axial line of the rotating shaft towards the third port 214 or away from the third port 214, and move to between the first port 212 and the second port 213 to block the first port 212 and the second port 213, while simultaneously communicating the first port 212 and the third port 214.

[0198] After the external drainage is completed, the electric motor controls the rotating shaft to rotate in a second preset direction, so that in the process of rotation of the first moving member 220 around the rotating shaft, the first moving member 220 can move along the axial line of the rotating shaft towards the third port 214 or away from the third port 214, and move to the third port 214 to block the third port 214, thereby preventing the backflow of residual water in the drain pipe 80.

[0199] For example, the second preset direction and the first preset direction are two directions opposite to each other.

[0200] Referring to FIGS. 17 and 18, the blocking member 230 includes a blocking member body 230A and a first blocking portion 2311 located on the outer circumferential surface of the blocking member body 230A.

[0201] The blocking member 230 can also have a first blocking portion 2311 and a second blocking portion 2312. The second blocking portion 2312 is located at the end face of the blocking member body 230A.

[0202] When the blocking member 230 moves along the first direction to the third 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 located at the circumferential side of the third port 214, to block the third port 214 and connect the first port 212 and the second port 213.

[0203] When the blocking member 230 moves along the first direction to the position between the first port 212 and the second port 213, the first blocking portion 2311 can abut against the circumferential inner wall of the mounting seat 210, to block the position between the first port 212 and the second port 213 and connect the first port 212 and the third port 214.

[0204] The control device 300 can be sealingly connected to the end of the mounting seat 210 away from the third port 214, to ensure the sealing of the third cavity 211 at the side adjacent to the control device 300, so that the liquid pumped into the third cavity 211 by the drainage pump 70 can flow to the second port 213 or the third port 214, to ensure the reliability of the operation of the inner circulation spraying and the external drainage function of the laundry treatment apparatus 10.

[0205] Based on the above, some embodiments of the present disclosure also provide another laundry treatment apparatus, which includes a third communication device. Similarly, the third communication device includes a mounting seat and a blocking member. In the another laundry treatment apparatus, the three ports of the mounting seat are respectively connected to the drainage pump, the drainage pipe and the spraying head. When drainage is needed after the end of the laundry washing, the control device can drive the blocking member in the communication device to rotate, to connect the first port and the third port, so that the water outlet end of the drainage pump is connected to the water inlet end of the drainage pipe. In this way, the mixed liquid in the outer drum and the inner drum can be pumped into the drainage pipe through the third port, and the mixed liquid can be drained from the drainage pipe to the outside of the housing.

[0206] After the drainage is completed, the control device can again drive the blocking member to rotate, to connect the first port and the second port in the communication device, to block the connection between the third port and the first port. In this way, when there is residual water in the drainage pipe, the residual water can be blocked by the communication device, to avoid the residual water in the drainage pipe from flowing back to the outer drum and the inner drum, effectively reducing or avoiding the residual water from flowing back to the outer drum and the inner drum to cause odor in the outer drum and the inner drum, and helping to improve the cleanliness of the outer drum and the inner drum and improve the laundry washing effect.

[0207] The structure of the laundry treatment apparatus 10 with the third communication device will be further described below in combination with the drawings and embodiments.

[0208] Referring to FIG. 19, the laundry treating apparatus 10 can include a communication device 200 through which the spray head 120 and the drain 80 can be connected to the drain pump 70, so that the water discharged from the drain pump 70 can reach the drain 80 or the spray head 120 through the communication device 200.

[0209] For example, referring to FIG. 20, the communication device 200 can include a mounting seat 210 and a blocking member 230, the mounting seat 210 can have a third cavity 211, and a first port 212, a second port 213, and a third port 214 communicating with the third cavity 211, and the spray head 120 and the drain 80 can be connected to the drain pump 70 through the mounting seat 210.

[0210] For example, the third cavity 211 can have a cylindrical structure, and a rotation shaft can be provided at a central portion of the third cavity 211, and an extension direction of the rotation shaft can be consistent with a central axis of the cylindrical third cavity 211. The blocking member 230 can be located in the third cavity 211, and the blocking member 230 can be rotationally connected to the rotation shaft, for example, the blocking member 230 can rotate around the rotation shaft.

[0211] The first port 212, the second port 213, and the third port 214 can be distributed along a circumference of the third cavity 211, for example, the first port 212 can communicate with a water outlet of the drain pump 70, the second port 213 can communicate with the spray head 120, for example, the second port 213 can communicate with the spray head 120 through the circulation line 90. The third port 214 can communicate with a water inlet of the drain 80. For example, the mounting seat 210 further includes a first pipe 215, the first port 212 is connected to the first pipe 215, and the first port 212 can communicate with the drain pump 70 through the first pipe 215. The mounting seat 210 further includes a second pipe 216, the second port 213 is connected to the second pipe 216, and the second port 213 can communicate with the circulation line 90 through the second pipe 216. The mounting seat 210 further includes a third pipe 217, the third port 214 is connected to the third pipe 217, and the third port 214 can communicate with the drain 80 through the third pipe 217.

[0212] The laundry treating apparatus 10 can further include a control device 300, the control device 300 can be connected to the blocking member 230, and the control device 300 can be configured to drive the blocking member 230 to rotate around the rotation shaft in the third cavity 211, so as to communicate the first port 212 with the second port 213 or the third port 214.

[0213] Referring to FIG. 20, during the washing of the laundry, the control device 300 can drive the blocking member 230 to rotate, to communicate the first port 212 with the second port 213, so as to communicate the water outlet end of the drainage pump 70 with the water inlet end of the circulation pipeline 90. In this case, the drainage pump 70 is started, and the drainage pump 70 can pump the mixed liquid in the outer drum 40 and the inner drum 50 out of the drainage port at the bottom of the outer drum 40, and into the circulation pipeline 90 through the second port 213, to be delivered to the spray head 120 through the circulation pipeline 90. The mixed liquid is sprayed from the spray head 120 at the top of the outer drum 40 to the laundry, so as to repeatedly wash the laundry, thus improving the washing effect on the laundry. In this way, the time for the laundry treatment apparatus 10 to wash the laundry is reduced, and the washing efficiency is improved.

[0214] Referring to FIGS. 21 and 22, when the laundry is washed and needs to be drained, the control device 300 can drive the blocking member 230 to rotate, to communicate the first port 212 with the third port 214, so as to communicate the water outlet end of the drainage pump 70 with the water inlet end of the drainage pipe 80. In this case, the drainage pump 70 is started, and the drainage pump 70 can pump the mixed liquid in the outer drum 40 and the inner drum 50 out of the drainage port at the bottom of the outer drum 40, and into the drainage pipe 80 through the third port 214, so as to drain the mixed liquid out of the drainage pipe 80 to the outside of the housing 20.

[0215] Referring to FIGS. 23 and 24, after the drainage is completed, the control device 300 can again drive the blocking member 230 to rotate, to communicate the first port 212 with the second port 213 in the communication device 200, so as to block the communication between the third port 214 and the first port 212. In this way, when there is residual water in the drainage pipe 80, the residual water can be blocked by the communication device 200, so as to avoid the residual water in the drainage pipe 80 from flowing back to the outer drum 40 and the inner drum 50, effectively reducing or avoiding the residual water from flowing back to the outer drum 40 and the inner drum 50 to cause the outer drum 40 and the inner drum 50 to produce an odor.

[0216] Continuing to refer to FIG. 22, when the blocking member 230 rotates to the second port 213, the blocking member 230 can block the second port 213, so that the first port 212 can communicate with the third port 214 through the third cavity 211. For example, when the laundry needs to be drained, the control device 300 can drive the blocking member 230 to rotate around the rotation shaft, so as to rotate the blocking member 230 to the second port 213. The blocking member 230 can block the second port 213, so as to block the communication between the second port 213 and the third cavity 211. In this case, the third port 214 is in an open state, and the third port 214 can communicate with the first port 212 through the third cavity 211.

[0217] 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 communication device 200, so that the drain pump 70 can pump the mixed liquid in the outer drum 40 and the inner drum 50 into the drain pipe 80 and then discharged to the outside of the housing 20 through the drain pipe 80.

[0218] For example, during the process of draining, the blocking member 230 blocks the second port 213 connected to the circulation pipeline 90, so that the mixed liquid is prevented from entering the circulation pipeline 90 during the process of draining, and then entering the outer drum 40 and the inner drum 50 through the circulation pipeline 90 and the spray head 120 to form residual water, which helps to improve the draining effect and reduce the residual water in the drum.

[0219] Referring to FIG. 24, when the blocking member 230 is rotated to the third port 214, the blocking member 230 can block the third port 214, so that the first port 212 can be connected to the second port 213 through the third cavity 211. For example, when it is necessary to drain, the control device 300 can drive the blocking member 230 to rotate around the rotation shaft, so that the blocking member 230 is rotated to the second port 213. The blocking member 230 can block the second port 213, so that the second port 213 is blocked from the third cavity 211. In this case, the third port 214 is in an open state, and the third port 214 can be connected to the first port 212 through the third cavity 211.

[0220] The water outlet end of the drain pump 70 can be connected to the water inlet end of the circulation pipeline 90 through the communication device 200, so that the drain 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 perform the circulation spray and rinse on the laundry.

[0221] For example, during the process of circulation spray, the blocking member 230 blocks the third port 214 connected to the drain pipe 80, so that the residual water in the drain pipe 80 is prevented from entering the circulation pipeline 90 during the process of washing the laundry, 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 to cause pollution.

[0222] Continuing to refer to FIG. 24, the laundry treatment apparatus 10 can further include a one-way valve 400, the water inlet end of the drain pump 70 is connected to the drain port of the outer drum 40, and the one-way valve 400 can be arranged at the water inlet end of the drain pump 70 or the drain port of the outer drum 40. The one-way valve 400 is configured to one-way conduct the drain port of the outer drum 40 to the water inlet end of the drain pump 70. In other words, the one-way valve 400 allows the water in the outer drum 40 to flow into the drain pump 70 through the one-way valve 400, and blocks the water in the drain pump 70, so that the water in the drain pump 70 cannot flow back to the outer drum 40 through the one-way valve 400.

[0223] Referring to FIGS. 20 and 22, during the process of circulating spraying and draining, the water in the outer tub 40 can flow to the drain pump 70 through the one-way valve 400 and to the circulating line 90 or the drain pipe 80 through the drain pump 70. Referring to FIG. 24, after the draining is completed and the laundry treating apparatus 10 is stopped, the one-way valve 400 can block the water path of the drain pump 70 toward the outer tub 40 to prevent the reverse flow of the external residual water from the drain port at the bottom of the outer tub 40 into the outer tub 40, which can effectively prevent the residual water from flowing into the outer tub 40 to cause odor or contamination, and can effectively function as a residual water barrier.

[0224] For example, the one-way valve 400 can be a rubber one-way valve, the first end of which is a circular ring-shaped open structure in a normally open state, and the second end of which is a flat closed state, for example, the annular inner wall of the one-way valve 400 is contracted and adhered. When installed, one end of the circular ring-shaped opening can face the outer tub 40, and the closed end can face the drain pump 70. During use, the water in the outer tub 40 can enter the one-way valve 400 from one end of the opening, and the closed port of the one-way valve 400 will be flushed open under the action of the gravity of the water and the suction of the drain pump 70, so that the closed end is in an open state, and the mixed liquid in the outer tub 40 can enter the drain pump 70.

[0225] When the draining is completed, the mixed liquid in the outer tub 40 is drained, and the end of the one-way valve 400 facing the drain pump 70 will return to the closed state, thereby preventing the water outside the outer tub 40 from flowing back into the outer tub 40 through the one-way valve 400, thereby effectively functioning as a residual water barrier.

[0226] Referring to FIG. 25, the laundry treating apparatus 10 can further include a first moving member 220, which can be connected with the blocking member 230 and rotationally connected with the rotation shaft, and the first moving member 220 can be connected with the control device 300. The first moving member 220 is configured to rotate around the rotation shaft under the action of the traction force of the control device 300 to drive the blocking member 230 to rotate around the rotation shaft.

[0227] For example, the first moving member 220 can be a traction rod, and the control device 300 can drive the first moving member 220 to reciprocate around the rotation shaft, so that the first moving member 220 can drive the blocking member 230 to reciprocate around the rotation shaft, and the blocking member 230 can switch between the position of the second port 213 and the position of the third port 214. Thus, the blocking member 230 can block the second port 213 or the third port 214.

[0228] For example, the blocking member 230 can be a structure member with ductility and elasticity, for example, the blocking member 230 can be a rubber member or the like, so that the blocking member 230 can seal the second port 213 or the third port 214 when the blocking member 230 is at the second port 213 or the third port 214, and the tightness of the contact between the blocking member 230 and the second port 213 or the third port 214 can be improved, so that the reliability of the blocking of the blocking member 230 can be effectively improved.

[0229] The first moving member 220 can be a structure member with certain strength and rigidity, and when the control device 300 drives the first moving member 220, the first moving member 220 can react and move under the driving of the control device 300, and the reliability of the movement of the first moving member 220 can be improved.

[0230] Continuing to refer to FIG. 25, the control device 300 can further include a control member 310, which can be connected with the first moving member 220, and the control member 310 can be configured to control the first moving member 220 to rotate around the rotation shaft, so that the first moving member 220 can drive the blocking member 230 to switch between the second port 213 and the third port 214.

[0231] For example, referring to FIG. 25, when it is needed to circulate the spraying, the control member 310 in the control device 300 can control the first moving member 220 to rotate around the rotation shaft, so that the first moving member 220 can drive the blocking member 230 to rotate to the third port 214, and the third port 214 is blocked, so that the drainage pump 70 can pump the mixed liquid into the circulation pipeline 90 connected with the second port 213.

[0232] Correspondingly, referring to FIG. 26, when it is needed to drain water, the control member 310 in the control device 300 can control the first moving member 220 to rotate around the rotation shaft, so that the first moving member 220 can drive the blocking member 230 to rotate to the second port 213, and the second port 213 is blocked, so that the drainage pump 70 can pump the mixed liquid into the drainage pipe 80 connected with the third port 214, and the mixed liquid can be drained out of the shell 20 through the drainage pipe 80.

[0233] Continuing to refer to FIGS. 25 and 26, the clothes treatment apparatus 10 can further include a first reset member 240, which can be located in the third cavity 211. A first end of the first reset member 240 can be connected with the blocking member 230, and a second end of the first reset member 240 can be connected with the mounting seat 210. When the control member 310 drives the blocking member 230 to rotate to the second port 213, the first reset member 240 can be in an elastically compressed state, and when the control member 310 releases the blocking member 230, the first reset member 240 can drive the blocking member 230 to rotate to the third port 214.

[0234] For example, when the control member 310 applies a driving force to the first moving member 220, the control member 310 can drive the first moving member 220 to rotate, so that the first moving member 220 can drive the blocking member 230 to rotate to the second port 213. In this case, the first reset member 240 can be in an elastic compression state, and the first reset member 240 in the elastic compression state can have a resilient force that can drive the blocking member 230 to rotate toward the third port 214. When the control member 310 releases the first moving member 220, the force of the control member 310 on the first moving member 220 is removed, and the first moving member 220 and the blocking member 230 are no longer driven by the driving force of the control device 300. In this case, the resilient force of the first reset member 240 can drive the blocking member 230 to rotate toward the position of the third port 214, so that the blocking member 230 blocks the third port 214.

[0235] The control device can control the first moving member 220 through the control member 310, so that the first moving member 220 can drive the blocking member 230 to rotate around the rotation shaft, so that the blocking member 230 can switch between the second port 213 and the third port 214, and realize switching between the first port 212 communicating with the second port 213 and the first port 212 communicating with the third port 214.

[0236] For example, when drainage is needed, the control device 300 can apply a driving force to the first moving member 220 through the control member 310 to drive the first moving member 220 to rotate, so that the first moving member 220 can drive the blocking member 230 to rotate to the second port 213 to block the second port 213, preventing the mixed liquid from entering the circulating pipeline 90 during the drainage process.

[0237] When the drainage is completed, the control device 300 removes the driving force of the control member 310 on the first moving member 220. In this case, the blocking member 230 can move to the third port 214 under the action of the first reset member 240 to block the third port 214, avoiding backflow of residual water in the drain pipe 80 into the outer cylinder 40 and the inner cylinder 50.

[0238] For example, referring to FIGS. 25 and 26, the first reset member 240 can be a torsion spring, which can be sleeved on the rotation shaft, and a first end of the torsion spring can be connected with the blocking member 230, and a second end of the torsion spring can be connected with the mounting seat 210. When the control member 310 drives the blocking member 230 to rotate to the second port 213 through the first moving member 220, the torsion spring can be in an elastic compression state. When the control member 310 removes the driving force on the first moving member 220, the blocking member 230 can reset to the third port 214 under the action of the resilient force of the torsion spring, so that the blocking member 230 can block the third port 214. In this way, the reliability and stability of the reset of the blocking member can be effectively improved.

[0239] For example, for the third communication device, the control device 300 can be a traction device, and the control member 310 can be a traction rope. For example, the traction rope can be a steel wire rope. During the process of draining, the traction device can pull the traction rope, so that the traction rope can pull the first moving member 220 to rotate, and the blocking member 230 can be blocked at the second opening 213. When the draining is completed, the traction device can release the traction rope, so that the traction rope is in a relaxed state, and the traction rope no longer exerts a pulling force on the first moving member 220. In this case, the blocking member 230 can rotate and reset to the third opening 214 under the elastic force of the first resetting member 240, so as to block the third opening 214, thereby preventing the residual water in the drain pipe 80 from flowing back.

[0240] In the related art, the spray holes on the spray head are usually circular holes, so that the liquid in the inner cylinder 50 and the outer cylinder 40 is sprayed through the spray holes to the inner cylinder 50, and the coverage area in the inner cylinder 50 is small and the pressure is low, the efficiency of washing the laundry is low, and the washing effect of the laundry treatment apparatus is poor.

[0241] Some embodiments of the present disclosure also provide a plurality of spray assemblies. The structure of the spray assembly of some embodiments of the present disclosure is further described below in combination with different embodiments.

[0242] Referring to FIG. 27, the laundry treatment apparatus 10 of some embodiments of the present disclosure can be provided with a liquid inlet pipeline and a spray assembly 100. The spray assembly 100 can have a spray head 120 connected to the water outlet end of the liquid inlet pipeline, and the spray head 120 is provided with spray holes 121 (see FIG. 30).

[0243] Some embodiments of the present disclosure improve the shape of the spray holes 121 of the spray head 120, so that when the liquid is sprayed through the spray holes 121, the pressure of the liquid can be increased, thereby increasing the spray area, and the liquid sprayed by the spray head 120 can cover a large area and wash the laundry in the inner cylinder 50. In this way, the efficiency of washing the laundry can be improved, and the washing effect can be improved.

[0244] In addition, the liquid sprayed by the spray head 120 to the inner cylinder 50 can also wash the inner cylinder 50, the door seal 60, the door body 30, etc., so as to avoid impurities such as foam generated by the detergent remaining in the inner cylinder 50 and the door body 30, thereby ensuring the washing effect of the laundry and the health of the user.

[0245] For example, the spray area of the spray assembly 100 can include the spray area of the spray holes 121. Correspondingly, the spray area of the spray assembly 100 can include the area occupied by the spray area of the spray holes 121.

[0246] The structure of the laundry treatment apparatus 10 provided with the first spray assembly 100 is further described below in combination with the drawings and embodiments.

[0247] Referring to FIGS. 27 to 30, the laundry treating apparatus 10 can include the liquid inlet conduit mentioned above.

[0248] Referring to FIGS. 28 to 31, the laundry treating apparatus 10 can further include a spraying assembly 100. The spraying assembly 100 can include a spray head 120. The spray head 120 can communicate with the water outlet end of the liquid inlet conduit. The liquid in the liquid inlet conduit is sprayed to the inner tub 50 through the spray head 120, so that the liquid in the liquid inlet conduit can be sprayed to the inner tub 50 through the spray head 120, thereby washing the laundry in the inner tub 50.

[0249] Referring to FIGS. 32 and 33, the spray head 120 can have a spray hole 121 spraying the liquid, so that the liquid in the liquid inlet conduit can be sprayed to the inner tub 50 through the spray hole 121, thereby washing the laundry in the inner tub 50.

[0250] Referring to FIGS. 32 and 33, along the flow direction of the liquid in the spray hole 121:

[0251] The spray hole 121 can have a third section 1211 (liquid inlet section) and a fourth section 1212 (liquid outlet section), for example, along the flow direction of the liquid in the spray hole 121, the inner contour of the third section 1211 can have a converging structure, and the inner contour of the fourth section 1212 can have a diverging structure.

[0252] In this way, along the flow direction of the liquid in the spray hole 121, the cross-sectional area of the third section 1211 decreases, and the cross-sectional area of the fourth section 1212 increases.

[0253] For example, the cross-sectional areas of the third section 1211 and the fourth 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 be referred to as the Z direction, and the axial direction of the spray hole 121 will be described below using the Z direction instead.

[0254] It should be understood that, in general, the flow rate of the liquid is inversely proportional to the cross-sectional area of the pipe when the liquid flows in the pipe.

[0255] The spray hole 121 can also be regarded as a kind of pipe. Since, along the flow direction of the liquid in the spray hole 121, the cross-sectional area of the third section 1211 decreases, when the liquid flows in the third section 1211, the flow rate of the liquid in the third section 1211 increases continuously during the flow of the liquid in the third section 1211. When the flow rate of the liquid increases to a critical point in the third section 1211, the flow rate will not increase any more. At the critical point of the flow rate of the liquid, the speed of the liquid is greater than the speed of sound.

[0256] When the velocity of the liquid is greater than the speed of sound, the aforementioned inverse relationship between the flow rate of the liquid and the cross-sectional area does not apply, but rather the opposite. In this case, the greater the cross-sectional area, the faster the flow rate of the liquid. Since the cross-sectional area of the fourth section 1212 increases along the flow direction of the liquid in the spray hole 121, when the liquid enters the fourth section 1212, the liquid continues to accelerate and exceeds the speed of sound, so that when the liquid is sprayed out of the spray hole 121, the flow rate instantaneously increases. For the spray hole 121, the flow rate is proportional to the pressure, so when the flow rate of the liquid instantaneously increases, the pressure of the liquid also instantaneously increases, which can effectively rinse the laundry in the inner tub 50 and improve the washing effect.

[0257] In this case, since the cross-sectional area of the fourth section 1212 gradually increases along the flow direction of the liquid in the spray hole 121, the spraying area of the liquid sprayed to the inner tub 50 via the fourth section 1212 can be increased, so that the liquid sprayed to the inner tub 50 via the spray hole 121 can cover and rinse the laundry in the inner tub 50 in a large area, thereby efficiently washing the laundry and improving the washing effect.

[0258] In addition, the liquid sprayed to the inner tub 50 by the spray head 120 has a high pressure and a large spraying area, and part of the door body 30 generally protrudes towards the inner tub 50, and the door seal 60 is located on the circumferential side of the protruding part of the door body 30, so that the liquid sprayed to the inner tub 50 by the spray head 120 can rinse the door body 30, the door seal 60, etc. in a larger area while rinsing the inner tub 50 in a large area, so as to avoid impurities such as foam generated by the detergent remaining in the inner tub 50, the door seal 60, and the door body 30, thereby improving the washing effect.

[0259] In some embodiments, when the liquid inlet pipeline is the circulation pipeline 90, the liquid (such as washing water) in the inner tub 50 and the outer tub 40 can be sprayed into the inner tub 50 via the spray hole 121, effectively rinsing the laundry in the inner tub 50, so that the laundry can be better soaked to enable the liquid to fully contact the stains attached to the surface of the laundry, thereby improving the washing effect.

[0260] In addition, by spraying the liquid to the laundry via the spray head 120, the liquid can be effectively sprayed on the laundry to reduce the entanglement between the laundry and improve the washing effect, while protecting the fabric quality of the laundry.

[0261] It should be noted that when the liquid inlet pipeline is the circulation pipeline 90, the washing effect of the laundry treatment apparatus 10 of some embodiments of the present disclosure is improved compared with the laundry treatment apparatus in the related art on the basis of achieving the same washing effect, and is beneficial to saving water and reducing energy consumption.

[0262] In some embodiments, when the liquid inlet pipe is a water inlet pipe, the liquid in the liquid inlet pipe can be water from an external water source flowing into the water inlet pipe. The water inlet pipe includes a water inlet pipe, a water inlet valve, and a water inlet pipe branch. The water inlet pipe is connected to the external water source, and the water inlet valve is arranged between the water inlet pipe and the water inlet pipe branch. The water inlet pipe branch is arranged in the housing 20. 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 in communication with the spray assembly 100. The water flowing through the water inlet pipe branch can carry the detergent into the inner drum 50 and be sprayed into the inner drum 50 through the spray holes 121, so as to soak the laundry and improve the washing effect. Moreover, when the water in the water inlet pipe is sprayed into the inner drum 50 through the spray holes 121, the entanglement between the laundry can be effectively reduced, the washing effect can be improved, and the fabric quality of the laundry can be protected.

[0263] It should be noted that the connection of the water inlet pipe, the water inlet valve, and the water inlet pipe branch can be determined according to the structure of the laundry treatment apparatus 10 in the related art.

[0264] Hereinafter, the structure of the laundry treatment apparatus 10 will be further described by taking the liquid inlet pipe as the circulation pipe 90 as an example.

[0265] Referring to FIG. 27, in some embodiments, the laundry treatment apparatus 10 can further include a communication device. The communication device can be a three-way valve or the like. The communication device is arranged in the housing 20. The communication device can selectively communicate the water outlet end of the drain pump 70 with the water inlet end of the circulation pipe 90 and the water inlet end of the drain pipe 80.

[0266] When the liquid in the inner drum 50 and the outer drum 40 needs to be circulated and sprayed, the communication device can communicate the water outlet end of the drain pump 70 with the water inlet end of the circulation pipe 90. 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 pipe 90, and then to the spray head 120 through the circulation pipe 90. The liquid sprayed out of the spray head 120 can wash the inner drum 50 wall, the laundry in the inner drum 50, the door body 30, and the door seal 60.

[0267] When the liquid in the inner drum 50 and the outer drum 40 needs to be drained to the outside of the housing 20, the communication device can communicate the water outlet end of the drain pump 70 with the water inlet end 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 drain pipe 80, and then the liquid can be drained to the outside of the housing 20 through the drain pipe 80.

[0268] During the washing, rinsing, and dehydration processes of the laundry treatment apparatus 10, the liquid in the liquid inlet pipe can be sprayed out of the spray holes 121 according to the program design of the laundry treatment apparatus 10, so as to wash the inner drum 50 wall, the laundry in the inner drum 50, the door body 30, and the door seal 60.

[0269] Hereinafter, the structure of the first spray assembly will be further described.

[0270] Referring to FIG. 34, in some embodiments, the inner diameter of the third section 1211 can decrease, the inner diameter of the fourth section 1212 can increase, and the inner diameters of the third section 1211 and the fourth section 1212 at the opposite ends can be equal along the flow direction of the liquid in the spray hole 121, so that the cross-sectional area of the third section 1211 decreases along the flow direction of the liquid in the spray hole 121, forming a converging structure, and the cross-sectional area of the fourth section 1212 increases, forming a diverging structure.

[0271] Further, since the inner diameters of the third section 1211 and the fourth section 1212 at the opposite ends are equal, the inner diameter of the spray hole 121 can smoothly transition between the third section 1211 and the fourth section 1212, so as to ensure that the liquid can flow to the fourth section 1212 along the predetermined water flow direction. Further, since the inner diameters of the third section 1211 and the fourth section 1212 at the opposite ends are equal, the spray hole 121 forms a narrow opening between the third section 1211 and the fourth section 1212, and when the liquid flows to the narrow opening through the third section 1211, the flow rate of the liquid is at the critical point mentioned above.

[0272] Referring to FIG. 34, when the inner diameters of the third section 1211 and the fourth section 1212 at the opposite ends are equal, the third section 1211 can directly connect with the fourth section 1212. Alternatively, when the inner diameters of the third section 1211 and the fourth section 1212 at the opposite ends are equal, the spray hole 121 can further have a second connecting portion, the third section 1211 and the fourth section 1212 connect at the second connecting portion, the inner diameter of the second connecting portion is constant along the flow direction of the liquid in the spray hole 121, and the inner diameter of the second connecting portion is equal to the minimum inner diameter of the third section 1211 and the fourth section 1212, so that the connection between the third section 1211 and the second connecting portion and the connection between the fourth section 1212 and the second connecting portion are smoothly transitioned, so as to ensure that the liquid can flow to the fourth section 1212 along the predetermined water flow direction.

[0273] Further, by directly connecting the third section 1211 and the fourth section 1212, or connecting the third section 1211 and the fourth section 1212 through the second connecting portion, the structure of the spray hole 121 can be diversified to meet the design requirements of different spray heads 120 for the spray hole 121.

[0274] Compared with the arrangement of the second connecting portion, when the third section 1211 and the fourth section 1212 directly connect, the pressure of the liquid is instantaneously increased, the spray area is increased, and the length of the spray hole 121 in the Z direction is 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.

[0275] Referring to FIGS. 35 and 36, in some embodiments, the spray head 120 can have a plurality of spray holes 121. The plurality of spray holes 121 can be provided on the side of the spray head 120 facing the inner tub 50, so that the liquid in the liquid inlet pipe can be sprayed into the inner tub 50 through the spray holes 121. By providing the plurality of spray holes 121, the spray area can be further enlarged, so that the washing effect and the flushing effect on the inner tub 50, the door seal 60, the door body 30, etc. can be improved.

[0276] For example, the spray head 120 can include two, three, four or more spray holes 121.

[0277] In FIGS. 35 and 36, four spray holes 121 are shown. The four spray holes 121 are provided on the side of the spray head 120 facing the inner tub 50, and three of the four spray holes 121 are provided around the remaining one spray hole 121. For example, the four spray holes 121 can also be arranged on the side of the spray head 120 facing the inner tub 50 along the circumference of the spray head 120.

[0278] In some embodiments, the spray head 120 can also have one spray hole 121. Compared with the plurality of spray holes 121, in the case of the same size of the spray head 120, the size of the spray hole 121 can be enlarged to enlarge the spray area, so that the washing effect and the flushing effect on the inner tub 50, the door seal 60, the door body 30, etc. can be improved.

[0279] Referring to FIG. 29, in some embodiments, the spray assembly 100 can further include a spray pipe 110. The spray pipe 110 is connected to the water outlet end of the liquid inlet pipe.

[0280] The spray assembly 100 can further include a fixing member 130. For example, the spray pipe 110 can be connected to the fixing member 130. For example, the spray pipe 110 can be detachably connected to the fixing member 130 by buckling, threading, etc., or the spray pipe 110 can be integrally connected to the fixing member 130 to form a structural member.

[0281] Referring to FIG. 42, the fixing member 130 can have a communication hole 131. The spray head 120 is mounted to the fixing member 130, and the spray head 120 is connected to the spray pipe 110 through the communication hole 131. In this way, the spray head 120 can be mounted to the water outlet end of the liquid inlet pipe through the fixing member 130 and the spray pipe 110, and the spray head 120 can also be connected to the water outlet end of the liquid inlet pipe through the communication hole 131 and the spray pipe 110, so that the liquid in the liquid inlet pipe can enter the spray head 120 through the spray pipe 110 and the communication hole 131, and finally be sprayed into the inner tub 50 through the spray holes 121.

[0282] In some embodiments, the spray pipe 110 can be fixed to the water outlet end of the liquid inlet pipe by clamping, screwing, welding, or the like, and is in communication with the water outlet end of the liquid inlet pipe. Similarly, the spray pipe 110 can be connected to the fixing member 130 by clamping, screwing, welding, or the like.

[0283] In some embodiments, when the spray head 120 is installed on the fixing member 130, the spray head 120 can not rotate relative to the fixing member 130, for example, the spray direction of the spray head 120 is towards the same direction. For example, the spray head 120 can be installed on the fixing member 130 by welding, clamping, or the like.

[0284] In some embodiments, when the spray head 120 is installed on the fixing member 130, the spray head 120 can rotate relative to the fixing member 130, so that the spray direction of the spray head 120 can be changed by rotating the spray head 120, thereby further expanding the spray area of the spray head 120, which is conducive to improving the cleaning effect. For example, the spray head 120 can be installed on the fixing member 130 by clamping, screwing, or the like.

[0285] Referring to FIG. 37, in some embodiments, the spray assembly 100 can be arranged on the door seal 60 and located at the side of the top of the door seal 60 facing the housing 20, so as to realize the installation of the spray assembly 100 in the housing 20. For example, 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 drum 50 through the spray holes 121, and the user can see the spray head 120 from the side of the door seal 60 away from the inner drum 40, so that the water flow sprayed by the spray head 120 is visualized, and the user can directly see the water flow sprayed by the spray head 120.

[0286] 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 drum opening of the outer drum 40 in the radial direction of the outer drum 40.

[0287] In some embodiments, the spray pipe 110 can be arranged through the door seal 60 and fixed to the door seal 60, and the water outlet end of the spray pipe 110 can be bent towards the inner drum 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 by the fixing member 130, the spray head 120 can be located at the side of the door seal 60 facing the inner drum 50.

[0288] In addition to the first spray assembly mentioned above, some embodiments of the present disclosure also provide a second spray assembly.

[0289] Different from the first spray assembly, the spray head 120 of the second spray assembly has a plurality of hole groups, which generate different water flow effects in the washing and rinsing processes of the laundry treatment apparatus 10. The user can rotate the spray head 120 to select one hole group that is in communication with the spray pipe 110 according to the type of laundry, so as to generate a water flow effect that is suitable for the type of laundry.

[0290] The differences between the second spray assembly and the first spray assembly will be further described below in conjunction with the accompanying drawings.

[0291] Referring to FIGS. 38 to 41, in some embodiments, the spray head 120 has a plurality of hole groups on the side of the spray head 120 that faces the inner tub 50. The plurality of hole groups can include a first hole group 122 and a second hole group 123. The first hole group 122 and the second hole group 123 each include spray holes 121. For example, the number of spray holes 121 in the second hole group 123 can be greater than the number of spray holes 121 in the first hole group 122.

[0292] Referring to FIGS. 42 and 43, when the number of spray holes 121 in the second hole group 123 is greater than the number of 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. For example, the size of the spray holes 121 can include, but is not limited to, the inner diameter of the spray holes 121. The inner diameter of the spray holes 121 can include, but is not limited to, the inner diameter of the third section 1211 and the inner diameter of the fourth section 1212 of the spray holes 121.

[0293] Since the water flow effect generated by the hole group is related to the size of the spray holes 121, the greater the size of the spray holes 121, the greater the pressure of the liquid in the liquid inlet pipeline when sprayed to the inner tub 50 via the hole group. In addition, the water flow effect generated by the hole group is also related to the size of the spray holes 121, the greater 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 tub 50 via the hole group, and the smaller the pressure.

[0294] Therefore, by limiting the size and number of spray holes 121 in the second hole group 123 and the first hole group 122, different water flow effects can be generated when the liquid in the liquid inlet pipeline is sprayed to the inner tub 50 via the first hole group 122 or the second hole group 123, so that the spray head 120 can generate a water flow effect that is suitable for the type of laundry, so as to perform washing, rinsing, and the like on the laundry.

[0295] For example, the first hole group 122 generates a concentrated water flow effect with large pressure, and the second hole group 123 generates a dispersed water flow effect with small flow pressure. The water flow generated by the first hole group 122 is suitable for washing clothes that need a strong water flow for washing. The water flow generated by the second hole group 123 is suitable for washing clothes that need a water flow with small water pressure for washing.

[0296] For example, the first hole group 122 can have one spray hole 121, and the second hole group 123 can have two, three, or four spray holes 121. Since the first hole group 122 has one spray hole 121, when the liquid in the liquid inlet pipeline is sprayed to the inner drum 50 via the first hole group 122, a single water flow can be generated. When the liquid in the liquid inlet pipeline is sprayed to the inner drum 50 via the second hole group 123, multiple water flows with small pressure can be generated.

[0297] Hereinafter, the structure of the clothes treatment apparatus 10 will be further described 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.

[0298] In some embodiments, the spray assembly 100 can have a jet hole 126. The liquid in the liquid inlet pipeline can also be jetted to the inner drum 50 via the jet hole 126 to expand the spray area of the spray assembly 100, thereby expanding the spray area of the spray assembly 100.

[0299] In addition to the spray area of the spray hole 121, the spray area of the spray assembly 100 can also include the jet area of the jet hole 126. Accordingly, the spray area of the spray assembly 100 can include the area occupied by the spray area of the spray hole 121 and the jet area of the jet hole 126.

[0300] Referring to FIGS. 44 and 45, in some embodiments, the spray assembly 100 can further include a booster 125 (insert).

[0301] Referring to FIGS. 44 and 46, the spray head 120 can have an embedding hole. The booster 125 is embedded in the embedding hole, and the circumferential outer wall of the booster 125 and the hole wall of the embedding hole can jointly form the jet hole 126, so that the liquid in the liquid inlet pipeline can be jetted to the inner drum 50 along the outer circumferential side of the booster 125 to form a closed waterfall water flow effect in the circumferential direction of the booster 125, thereby further enhancing the diversity of the water flow effect on the basis of the first hole group 122 and the second hole group 123 to adapt to more types of clothes.

[0302] In some embodiments, referring to FIGS. 44 and 46, the plurality of hole groups can further include a third hole group 124. The third hole group 124 can have at least one jet 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, a plurality of different water flow effects can be generated when the laundry treatment apparatus 10 is operated in a washing, rinsing or the like program.

[0303] The water flow generated by the jet hole 126 has a pressure less than that of the water flow generated by the second hole group 123, and thus the water flow generated by the third hole group 124 is suitable for washing laundry requiring a gentle water flow.

[0304] For example, the third hole group 124 can have one or two jet holes 126. Any one of the one or two jet holes 126 can correspond to one booster 125, respectively. Hereinafter, the structure of the laundry treatment apparatus 10 will be further described taking one jet hole 126 as an example.

[0305] For example, the booster 125 can be a structural member mounted on the spray head 120 in a screwing manner by a screw, a bolt or the like.

[0306] Referring to FIG. 45, in a second spray assembly, the spray head 120 can be rotatable relative to the fixing member 130 to connect the spray pipe 110 to any one of the plurality of hole groups, so that the user can rotate the spray head 120 according to the demand of the laundry for the water flow. In this way, when the laundry treatment apparatus 10 is operated in a washing, rinsing or the like program, the user can generate a water flow effect suitable for the laundry to be washed by the selected hole group.

[0307] For example, when the laundry to be washed requires a gentle water flow, the user can rotate the spray head 120 to connect the third hole group 124 to the spray pipe 110; when the laundry to be washed requires a plurality of water flows with a small pressure, the user can rotate the spray head 120 to connect the second hole group 123 to the spray pipe 110; and when the laundry to be washed requires a powerful water flow, the user can rotate the spray head 120 to connect the first hole group 122 to the spray pipe 110.

[0308] It should be noted that in addition to the demand of the laundry for the water flow, the user can also select different hole groups to be connected to the spray pipe 110 according to different selected programs, so as to generate different water flow effects.

[0309] Referring to FIG. 45, in some embodiments, the spray head 120 can have a clamping portion 127. The clamping portion 127 can be clamped to the side of the fixing member 130 facing the spray pipe 110, and the spray head 120 can be rotatable relative to the fixing member 130 so that the user can rotate the spray head 120.

[0310] Referring to FIGS. 45 and 46, in some embodiments, the side of the fixing member 130 facing the shower head 120 is provided with a deformable limiting portion 132 (a protruding portion). The limiting portion 132 is located at the edge region of the fixing member 130. The side of the shower head 120 facing the fixing member 130 is provided with a positioning portion 129 that is engaged with the limiting portion 132. The positioning portion 129 is located at the edge region of the shower head 120.

[0311] Referring to FIG. 44, the shower head 120 is provided with a positioning portion 129 at the position corresponding to each group of holes. The positioning portion 129 can be a groove or other structure on the shower head 120 that can engage the limiting portion 132. Each positioning portion 129 can be distributed circumferentially along the shower head 120. When the shower head 120 is rotated relative to the fixing member 130 until the limiting portion 132 is engaged in one positioning portion 129, the spray pipe 110 can be connected to one group of holes, and the group of holes connected to the spray pipe 110 corresponds to the positioning portion 129 that engages the limiting portion 132.

[0312] In this way, during rotation of the shower head 120, and before the limiting portion 132 is rotated into the positioning portion 129, the shower head 120 will press the limiting portion 132, so that the limiting portion 132 can be deformed towards the spray pipe 110. When the limiting portion 132 is rotated into the positioning portion 129, the pressing of the limiting portion 132 by the shower head 120 disappears, and the limiting portion 132 is engaged in the positioning portion 129, thereby connecting the group of holes corresponding to the positioning portion 129 to the spray pipe 110. During rotation of the limiting portion 132 into the next positioning portion 129, the limiting portion 132 will be deformed again under the pressing of the shower head 120, until the limiting portion 132 is engaged in the next positioning portion 129.

[0313] Therefore, by rotating the shower head 120, the limiting portion 132 can be engaged in any positioning portion 129, and any group of holes can be positioned, so that any group of holes can be connected to the spray pipe 110 in sequence during rotation, to obtain different water flow effects.

[0314] Referring to FIG. 45, in some embodiments, the fixing member 130 can be provided with a first connecting portion 133 (a cantilever). The free end of the first connecting portion 133 is an edge region of the fixing member 130, and the side of the free end of the first connecting portion 133 facing the shower head 120 is provided with a limiting portion 132, so that the limiting portion 132 is arranged at the edge region of the fixing member 130. Moreover, before the limiting portion 132 rotates to the positioning portion 129, the shower head 120 will press the limiting portion 132, so that the first connecting portion 133 deforms towards the shower pipe 110, and the limiting portion 132 deforms towards the shower pipe 110 at the same time, to ensure that the limiting portion 132 can deform. When the limiting portion 132 rotates to the positioning portion 129, the pressing of the limiting portion 132 by the shower head 120 disappears, and the limiting portion 132 resets towards the shower head 120, and the first connecting portion 133 resets towards the shower head 120 at the same time.

[0315] Alternatively, in some embodiments, the limiting portion 132 can also be a flexible protrusion on the fixing member 130. In this case, the first connecting portion 133 does not need to be provided on the fixing member 130 while the limiting portion 132 deforms and is clamped in the positioning portion 129, which can simplify the structure of the fixing member 130.

[0316] The shower head 120 can be circular or square, and the following will be further described with the structure of the clothes treatment apparatus 10 taking the circular shower head 120 as an example.

[0317] Referring to FIGS. 44 and 45, in some embodiments, along the radial direction of the shower head 120, the limiting portion 132 can be opposite to the communication hole 131 of the fixing member 130, and the limiting portion 132 and the communication hole 131 are located on both sides of the shower head 120, so that the limiting portion 132 is arranged at the edge region of the fixing member 130.

[0318] It should be noted that, along the radial direction of the shower head 120, the limiting portion 132 can be opposite to the communication hole 131 of the fixing member 130, which can be understood as that, along the radial direction of the shower head 120, the limiting portion 132 is arranged opposite to the communication hole 131.

[0319] When the shower head 120 rotates relative to the fixing member 130 to the limiting portion 132 clamped in any one of the positioning portions 129, the hole group of the shower pipe 110 can be connected in communication with the shower pipe 110 through the communication hole 131.

[0320] Referring to FIG. 44, along the radial direction of the shower head 120, any one of the hole groups can be provided with one positioning portion 129, and the hole group and the corresponding positioning portion 129 can be distributed on both sides of the radial direction of the shower head 120.

[0321] The following will be further described with the structure of the clothes treatment apparatus 10 taking three hole groups as an example.

[0322] For the convenience of description, the positioning part 129 corresponding to the first hole group 122 is defined as the first positioning part 1291, the positioning part 129 corresponding to the second hole group 123 is defined as the second positioning part 1292, and the positioning part 129 corresponding to the third hole group 124 is defined as the third positioning part 1293.

[0323] Referring to FIGS. 38, 39 and 42, when the shower head 120 is rotated relative to the fixing member 130 to the position where the limiting part 132 is clamped in the first positioning part 1291, it indicates that the first hole group 122 is selected, and the first hole group 122 can be connected to the shower pipe 110 through the communication hole 131.

[0324] Referring to FIGS. 40, 41 and 43, when the shower head 120 is rotated relative to the fixing member 130 to the position where the limiting part 132 is clamped in the second positioning part 1292, it indicates that the second hole group 123 is selected, and the second hole group 123 can be connected to the shower pipe 110 through the communication hole 131.

[0325] Referring to FIGS. 44 to 46, when the shower head 120 is rotated relative to the fixing member 130 to the position where the limiting part 132 is clamped in the third positioning part 1293, it indicates that the third hole group 124 is selected, and the third hole group 124 can be connected to the shower pipe 110 through the communication hole 131.

[0326] Referring to FIG. 44, the centers of the first positioning part 1291, the second positioning part 1292 and the third positioning part 1293 can be located on a first circle. When the shower head 120 is rotated relative to the fixing member 130, the first circle can serve as the rotation track of the limiting part 132, so that the limiting part 132 can be clamped in any positioning part 129 when the shower head 120 is rotated relative to the fixing member 130.

[0327] Correspondingly, the centers of the first hole group 122, the second hole group 123 and the third hole group 124 can be located on a second circle. When the shower head 120 is rotated relative to the fixing member 130, the second circle can serve as the rotation track of the center of the communication hole 131, so that the center of any hole group can coincide with the center of the communication hole 131 when the shower head 120 is rotated relative to the fixing member 130, and any hole group can be connected to the shower pipe 110 through the communication hole 131.

[0328] Referring to FIG. 46, in some embodiments, the shower assembly 100 can further include a sealing member 134. The sealing member 134 can be a sealing ring or other structure capable of sealing. The sealing member 134 is arranged around the communication hole 131 to seal the gap between the fixing member 130 and the shower head 120. The gap between the selected hole group and the fixing member 130 in the communication hole 131 can be sealed by the sealing member 134, so as to avoid the liquid flowing through the communication hole 131 from entering the unselected hole group, thereby affecting the water flow effect of the shower head 120.

[0329] In some embodiments, part of the sealing member 134 can be embedded on the side of the fixing member 130 facing the shower head 120 to achieve the installation of the sealing member 134 on the fixing member 130. Alternatively, in some embodiments, the sealing member 134 can also be installed on the side of the fixing member 130 facing the shower head 120 by means of adhesion or the like.

[0330] Referring to FIGS. 42, 43 and 46, the side of the shower head 120 away from the fixing member 130 is provided with a plurality of second holding portions 128 (protruding blocks). The number of the second holding portions 128 corresponds to the number of the hole groups, and each of the plurality of second holding portions 128 is provided with a hole group. In this way, when the user rotates the shower head 120, the second holding portions 128 can be acted on to facilitate the user to apply force to the shower head 120 to rotate the shower head 120.

[0331] The projection area of each of the second holding portions 128 on the shower head 120 can be equal, that is, the hole opening area of each of the hole groups on the shower head 120 can be equal. The shape of the end of the second holding portion 128 facing the fixing member 130 can match the shape of the communication hole 131.

[0332] When the shape of the end of the second holding portion 128 facing the fixing member 130 matches the shape of the communication hole 131, the structure of the sealing member 134 can also match the shape of the communication hole 131 so that the sealing member 134 can seal the gap between the selected hole group and the fixing member 130.

[0333] Referring to FIG. 47, a second shower assembly is arranged on the door seal 60, and the shower head 120 is arranged towards the inner drum 50. For example, the arrangement position and arrangement manner of the second shower assembly 100 on the door seal 60 can refer to the related description of the first shower assembly described above, and will not be described here again.

[0334] It can be understood that the washing water entering the shower head 120 usually contains lint. After the laundry treatment apparatus 10 is used for a long time, the lint is easy to accumulate in the shower head 120 and block the shower head 120.

[0335] However, the shower head in the related art is fixedly connected to the water outlet end of the shower pipe, which makes it inconvenient to disassemble the shower head from the shower pipe, resulting in difficulty in cleaning the accumulated lint in the shower head.

[0336] Referring to FIGS. 48 and 49, the first spray assembly 100 of some embodiments of the present disclosure includes a spray pipe 110, a fixing member 130, and a spray head 120. The fixing member 130 is mounted to the water outlet end of the spray pipe 110. The spray head 120 can be detachably mounted to the water outlet end of the spray pipe 110 by being clamped or screwed into the fixing member 130. The user can detach the spray head 120 by unclamping or unscrewing the spray head 120 from the fixing member 130, so as to clean or wash the lint and other impurities in the spray head 120, thereby preventing the spray head 120 from being blocked or the dirt on the surface of the spray head 120 from contaminating the washing water and affecting the washing effect.

[0337] It should be noted that the spray assembly 100 can be mounted to the water outlet end of the liquid inlet pipeline. For example, the spray pipe 110 can be mounted to the water outlet end of the liquid inlet pipeline and can be in communication with the water outlet end of the liquid inlet pipeline.

[0338] As described above, the liquid inlet pipeline can include the circulation pipeline 90, the water inlet pipeline, or other liquid inlet passages in the laundry treatment apparatus 10.

[0339] Hereinafter, the structure of the spray assembly 100 and the laundry treatment apparatus 10 will be further described with the liquid inlet pipeline being the circulation pipeline 90 as an example.

[0340] The structure of the first spray assembly and the laundry treatment apparatus 10 will be further described below with reference to FIG. 49.

[0341] Referring to FIG. 49, the spray assembly 100 can include the spray pipe 110. The spray pipe 110 can be configured to be in communication 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.

[0342] The spray assembly 100 can include the fixing member 130 and the spray head 120. The fixing member 130 can be mounted to the water outlet end of the spray pipe 110. The fixing member 130 has a first cavity 1301 therein. The first cavity 1301 is in communication with the water outlet end of the spray pipe 110.

[0343] The spray assembly 100 can include the spray head 120. The spray head 120 can be disposed in the fixing member 130, and the spray head 120 can be provided with a through hole and spray holes 121. The spray holes 121 are in communication with the first cavity 1301 and face the inner tub 50. In this way, the spray head 120 can be in communication with the liquid inlet pipeline through the fixing member 130 and the spray pipe 110, so that the liquid in the liquid inlet pipeline can flow into the spray pipe 110, the first cavity 1301, and the spray holes 121, and be sprayed into the inner tub 50 through the spray holes 121.

[0344] In addition, part of the door body 30 protrudes towards the inner drum 50, and the door seal 60 is located on the circumferential 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 in a large area, but also flush the door body 30, the door seal 60, etc. in a large area to avoid residues such as foam generated by the detergent remaining in the inner drum 50, the door seal 60, and the door body 30, thereby improving the cleaning effect.

[0345] Referring to FIG. 48, the spray pipe 110 can be provided in the door seal 60 and on the side of the door seal 60 facing the top of the laundry treatment apparatus 10. For example, when the spray pipe 110 is provided in the door seal 60, the spray pipe 110 can face the top of the housing 20. The spray head 120 is exposed to the inside of the door seal 60 so as to facilitate the disassembly of the spray head 120, and a user can see the spray head 120 from the side of the door seal 60 away from the inner drum 40, so that the water flow sprayed from the spray head 120 is visualized and the user can directly see the water flow sprayed from the spray head 120.

[0346] Referring to FIG. 48, in some embodiments, the laundry treatment apparatus 10 can further include a communication device. The communication device can be a three-way valve or the like. The communication device is provided in the housing 20. The communication device can selectively communicate the water outlet of the drain pump 70 with the water inlet of the circulation line 90 and the water inlet of the drain pipe 80.

[0347] When the liquid in the inner drum 50 and the outer drum 40 needs to be circulated and sprayed, the communication device can communicate the water outlet of the drain pump 70 with the water inlet of the circulation line 90. When the drain pump 70 is activated, the drain pump 70 can pump the liquid in the inner drum 50 and the outer drum 40 into the circulation line 90, and then to the spray head 120 via the circulation line 90. The liquid sprayed from the spray head 120 can flush the inner drum 50 wall, the laundry in the inner drum 50, the door body 30, and the door seal 60.

[0348] When the liquid in the inner drum 50 and the outer drum 40 needs to be drained to the outside of the housing 20, the communication device can communicate the water outlet of the drain pump 70 with the water inlet of the drain pipe 80. When the drain pump 70 is activated, the drain pump 70 can pump the liquid in the inner drum 50 and the outer drum 40 into the drain pipe 80, and then the liquid can be drained to the outside of the housing 20 via the drain pipe 80.

[0349] During the washing, rinsing, and dehydration processes of the laundry treatment apparatus 10, the liquid in the liquid inlet line can be sprayed from the spray hole 121 at any time according to the program design of the laundry treatment apparatus 10, to flush the inner drum 50 wall, the laundry in the inner drum 50, the door body 30, and the door seal 60.

[0350] Referring to FIG. 49, in some embodiments, the spraying assembly 100 can further include a clamping member 140. The clamping member 140 can be inserted into the insertion hole and clamped with the fixing member 130 to mount the spraying head 120 in the fixing member 130.

[0351] The clamping member 140 can be used to clamp the spraying head 120 with the fixing member 130, so that the spraying head 120 can be mounted in the fixing member 130 through the clamping member 140, and then the spraying head 120 can be detachably mounted on the water outlet end of the spraying pipe 110 through the fixing member 130. When it is necessary to detach the spraying head 120, the user can release the clamping of the spraying head 120 with the fixing member 130, so as to realize the detachment of the spraying head 120. In this way, the user can clean and wash the impurities such as hair in the spraying head 120, prevent the spraying head 120 from being blocked or the dirt attached to the surface of the spraying head 120 from polluting the washing water, and affect the washing effect.

[0352] The clamping member 140 can be a flexible member or a non-flexible member. For example, the flexible member includes a structural member made of a material such as rubber, which has ductility and elasticity, and the non-flexible member includes a structural member made of a material such as metal or plastic, which has certain strength and rigidity. When the clamping member 140 is a flexible member, when it is necessary to detach the spraying head 120, the user can apply a force to the flexible member to deform the flexible member, so that the flexible member can be pulled out of the insertion hole. After the flexible member is pulled out of the insertion hole, the clamping of the spraying head 120 with the fixing member 130 can be released, so as to realize the detachment of the spraying head 120.

[0353] Hereinafter, the structure of the clamping member 140 will be further limited by taking the clamping member 140 as a flexible member as an example.

[0354] The clamping member 140 can be a rubber member with certain hardness, or a plastic member with certain flexibility, etc.

[0355] Referring to FIG. 49, in some embodiments, when the clamping member 140 is a flexible member, the two ends of the clamping member 140 can be respectively provided with a clamping portion 141 and a pressing portion 142.

[0356] Referring to FIGS. 49 and 50, the fixing member 130 can have a clamping portion 1303 located on the side of the spraying head 120 facing the spraying pipe 110. The clamping portion 141 is located on the side of the clamping portion 1303 facing the spraying pipe 110 and clamped with the clamping portion 1303. Through the cooperation of the clamping portion 141 and the clamping portion 1303, the clamping member 140 can be mounted on the fixing member 130.

[0357] Referring to FIG. 49, in some embodiments, the side of the spray head 120 facing the spray pipe 110 can be provided with a mounting portion 1201. The mounting portion 1201 can be arranged in the fixing member 130. The mounting portion 1201 is located on the side of the clamping portion 1303 away from the spray pipe 110 and abuts against the clamping portion 1303. The pressing portion 142 presses the other side of the mounting portion 1201, so that the mounting portion 1201 can be mounted in the fixing member 130 and fixed relative to the fixing member 130 by cooperation of the clamping portion 1303 and the pressing portion 142, thereby achieving detachable mounting of the spray head 120 in the fixing member 130.

[0358] By arranging the pressing portion 142, the user can press the pressing portion 142 when disassembling the spray head 120, so that the pressing portion 142 deforms. In this case, the pressing portion 142 cannot press the other side of the mounting portion 1201. Without the pressing of the mounting portion 1201 by the pressing portion 142, the mounting portion 1201 can be directly taken out of the fixing member 130, thereby achieving quick disassembly of the spray head 120.

[0359] Referring to FIG. 49, the spray head 120 has a spraying portion 1202 on the side away from the spray pipe 110. The spraying portion 1202 can be provided with spray holes 121. The axis of the spray hole 121 can be arranged at an angle to the length direction of the fixing member 130, so that the axis of the spray hole 121 is inclined toward the direction away from the clamping member 140, thereby expanding the spraying area of the spray hole 121 and the spraying area of the spray assembly 100, and improving the washing effect. The length direction of the fixing member 130 is parallel to the W direction (as shown in FIG. 51).

[0360] The spraying area of the spray assembly 100 can include the spraying area of the spray hole 121. Correspondingly, the spraying area of the spray assembly 100 can include the area occupied by the spraying area of the spray hole 121.

[0361] Referring to FIG. 50, in some embodiments, the spraying portion 1202 can be provided with a plurality of spray holes 121. For example, the spraying portion 1202 can be provided with two, three, four or the like spray holes 121. Along the circumferential direction of the spray head 120, the plurality of spray holes 121 can be distributed on the spraying portion 1202 at intervals, so that the liquid in the liquid inlet pipeline generates uniform water flow after passing through the spray holes 121, thereby expanding the spraying area of the spray assembly 100 and improving the washing effect.

[0362] Referring to FIGS. 49 and 50, in some embodiments, the fixing member 130 can include a first fixing portion 1304. The first fixing portion 1304 can be mounted to the water outlet end of the spray pipe 110. For example, the first fixing portion 1304 can be mounted to the water outlet end of the spray pipe 110 by screwing, clamping, or welding, etc. The fixing member 130 can further include a second fixing portion 1305 and a connecting rib. The second fixing portion 1305 can be arranged inside the first fixing portion 1304 and connected to the first fixing portion 1304 by the connecting rib. The circumferential outer wall of the second fixing portion 1305 and the circumferential inner wall of the first fixing portion 1304 jointly form a first cavity 1301. The end of the first fixing portion 1304 facing the spray pipe 110 has a communication hole, and the first cavity 1301 can be in communication with the spray pipe 110 through the communication hole.

[0363] The mounting portion 1201 is arranged in the second fixing portion 1305, and the end of the second fixing portion 1305 facing the spray pipe 110 is provided with a clamping portion 1303. The clamping portion 1303 has a first opening, and the clamping portion 141 can pass through 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 cooperation of the clamping portion 1303 and the pressing portion 142 can achieve the detachable connection of the spray head 120 and the fixing member 130.

[0364] Referring to FIGS. 49 and 51, in order to facilitate the deformation of the clamping member 140, the clamping member 140 can include a cavity, and the clamping portion 141 is provided with a second opening in communication with the cavity, so that when the pressing portion 142 is pressed, the pressing portion 142 can be deformed.

[0365] In addition, when the user applies a force to the pressing portion 142 to pull the clamping member 140 out of the through hole, the clamping portion 141 can be deformed and contracted towards the direction close to the second opening, so that the clamping portion 141 can pass through the through hole, and the clamping member 140 can be pulled out of the through hole, achieving the disassembly of the spray head 120.

[0366] Referring to FIGS. 49 and 52, when the user installs the spray head 120, the mounting portion 1201 of the spray head 120 can be first installed in the second fixing portion 1305, and then the clamping member 140 is arranged in the through hole, so that the clamping portion 141 abuts against the clamping portion 1303, and the pressing portion 142 presses the mounting portion 1201, achieving the installation of the spray head 120 in the fixing member 130. Alternatively, the user can first arrange the clamping member 140 in the through hole, so that the clamping member 140 and the spray head 120 are installed in the second fixing portion 1305, and the clamping member 140 achieves the clamping of the spray head 120 and the second fixing portion 1305.

[0367] Referring to FIG. 52, in some embodiments, the clamping member 140 is provided with a deformable connecting arm in the circumferential direction. The connecting arm can form the pressing portion 142. Alternatively, the end of the clamping member 140 away from the shower pipe 110 can form the pressing portion 142. Compared to the case where the end of the clamping member 140 away from the shower pipe 110 forms the pressing portion 142, when the connecting arm forms the pressing portion 142, the pressing portion 142 can be pressed against the mounting portion 1201 while facilitating the user to accurately press the pressing portion 142, so that the pressing portion 142 can be deformed to improve the disassembly efficiency of the shower head 120.

[0368] In some embodiments, the clamping member 140 includes a plurality of pressing portions 142. For example, the clamping member 140 can have two pressing portions 142. The plurality of pressing portions 142 can be distributed in the circumferential direction of the clamping member 140 to uniformly bear the force, so that the pressing portions 142 can be quickly deformed to further improve the disassembly efficiency of the shower head 120. Alternatively, the clamping member 140 includes one pressing portion 142, in which case the pressing portion 142 can be a closed structure surrounding the circumference of the clamping portion 141.

[0369] In some embodiments, the shower assembly 100 can have a spraying hole. For example, the spraying hole can include a first spraying hole 143, a second spraying hole 1203, etc. The liquid in the liquid inlet pipeline can also be sprayed to the inner cylinder 50 through the spraying hole to expand the spraying area of the shower assembly 100, thereby expanding the spraying area of the shower assembly 100.

[0370] When the shower assembly 100 includes a spraying hole, in addition to the spraying area of the spraying hole 121, the spraying area of the shower assembly 100 also includes the spraying area of the spraying hole. Accordingly, the spraying area of the shower assembly 100 includes not only the area occupied by the spraying area of the spraying hole 121, but also the area occupied by the spraying area of the spraying hole.

[0371] Referring to FIG. 51, in some embodiments, the clamping member 140 can have a first spraying hole 143. The first spraying hole 143 is in communication with the first 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 spraying hole 143, thereby expanding the spraying area of the shower assembly 100, expanding the spraying area of the shower assembly 100, and improving the washing effect.

[0372] It should be noted that in some embodiments, the clamping member 140 can also not be provided with the first spraying hole 143. Hereinafter, the structure of the first type of shower assembly will be further described with the clamping member 140 having the first spraying hole 143 as an example.

[0373] Referring to FIGS. 52 and 53, in some embodiments, the fixing member 130 can be an open end 1302 at an end distal from the spray pipe 110. The open end 1302 is in communication with the first cavity 1301. The spray portion 1202 can be disposed in the open end 1302, and the circumferential outer wall of the spray portion 1202 and the circumferential inner wall of the open end 1302 together define a second spray hole 1203. For example, the second spray hole 1203 is in communication with the first cavity 1301 and faces the inner tub 50, so that the liquid in the liquid inlet pipeline can also be sprayed to the inner tub 50 through the second spray hole 1203, further expanding the spraying area of the spraying assembly 100 and improving the cleaning effect. Moreover, since the second spray hole 1203 is located outside the spray hole 121, the spray hole 121 can cooperate with the second spray hole 1203 to enhance the washing effect on the inner tub 50, the door seal 60, and the door body 30, thereby improving the cleaning effect.

[0374] Referring to FIG. 53, in some embodiments, along the circumference of the spray head 120, the circumferential outer wall of the spray portion 1202 and the circumferential inner wall of the open end 1302 can have a gap therebetween, and the circumferential outer wall of the spray portion 1202 and the circumferential inner wall of the open end 1302 can together define an annular hole. The annular hole forms the second spray hole 1203, so that the liquid in the liquid inlet pipeline can also be sprayed to the inner tub 50 through the second spray hole 1203.

[0375] The second spray hole 1203 can be a tapered hole. The tapered hole 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 tub 50, so that when the liquid in the liquid inlet pipeline is sprayed to the inner tub 50 through the second spray hole 1203, the spraying area of the spraying assembly 100 can be expanded.

[0376] Referring to FIG. 53, the circumferential inner wall of the open end 1302 can define a shape that is tapered, 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 tub 50. The circumferential outer wall of the spray portion 1202 defines a shape that matches the shape defined by the circumferential inner wall of the open end 1302.

[0377] When the shape defined by the circumferential outer wall of the spray portion 1202 matches the shape defined by the circumferential inner wall of the open end 1302, the shape defined by the circumferential outer wall of the spray portion 1202 is also tapered, and also has a small-diameter end facing the spray pipe 110 and a large-diameter end facing the inner tub 50.

[0378] Alternatively, the shape defined by the circumferential inner wall of the open end 1302 can be cylindrical, in which case the shape defined by the circumferential outer wall of the spray portion 1202 can also be cylindrical.

[0379] Compared with the case where the circumferential inner wall of the open end 1302 forms a cylindrical shape, when the circumferential inner wall of the open end 1302 forms a conical shape, the spraying area of the second spraying hole 1203 and the spraying assembly 100 can be enlarged while ensuring that the liquid in the liquid inlet pipeline is sprayed to the inner cylinder 50 through the second spraying hole 1203, thereby further enlarging the spraying area of the second spraying hole 1203 and the spraying assembly 100.

[0380] In some embodiments, the gap between the circumferential outer wall of the spraying part 1202 and the circumferential inner wall of the open end 1302 along the circumference of the spraying head 120 can also be divided into a plurality of second spraying holes 1203 that are independent of each other and can spray the liquid in the liquid inlet pipeline to the inner cylinder 50. Compared with the case where the gap between the circumferential outer wall of the spraying part 1202 and the circumferential inner wall of the open end 1302 is divided into a plurality of second spraying holes 1203, when the circumferential outer wall of the spraying part 1202 and the circumferential inner wall of the open end 1302 define one second spraying hole 1203, the flow space of the liquid in the liquid inlet pipeline in the second spraying hole 1203 can be enlarged, so that impurities such as wire scraps are less likely to block the second spraying hole 1203.

[0381] On the basis of the above, some embodiments of the present disclosure also provide a second spraying assembly. The difference between the second spraying assembly and the first spraying assembly mentioned above is that, in the second spraying assembly, the spraying head 120 is screwed into the fixing member 130 to achieve detachable connection of the spraying head 120 and the fixing member 130, and the spraying head 120 can open or block the second spraying hole 1203 during screwing, so that the spraying assembly 100 can spray water flow of different forms and intensities, so that the user can select the type of water flow according to personal needs or the type of clothes to be cleaned.

[0382] The difference of the second spraying assembly will be further described below in combination with the drawings and embodiments.

[0383] Referring to FIGS. 54-56, as described above, the fixing member 130 has an open end 1302 at the end away from the spraying pipe 110, and the open end 1302 is in communication with the first cavity 1301. In some embodiments, the spraying head 120 can be screwed into the fixing member 130 and fixed relative to the fixing member 130. That is, the spraying head 120 is screwed into the fixing member 130, and the position of the spraying head 120 relative to the fixing member 130 is fixed without the action of external force.

[0384] For example, the mounting part 1201 of the spraying head 120 can be arranged in the second fixing part 1305 and threadedly connected with the second fixing part 1305, so as to screw the spraying head 120 into the fixing member 130 and ensure that the spraying head 120 is fixed relative to the second fixing part 1305 without the action of external force.

[0385] For example, the mounting portion 1201 can be provided with external threads, and the second fixing portion 1305 can be provided with internal threads, so that when the mounting portion 1201 is arranged in the second fixing portion 1305, the mounting portion 1201 and the second fixing portion 1305 can be threadedly connected.

[0386] The spraying portion 1202 is arranged in the open end 1302, and the circumferential outer wall of the spraying portion 1202 and the circumferential inner wall of the open end 1302 can jointly form the second spraying hole 1203. The spraying portion 1202 is provided with spraying holes 121, and the shapes of the spraying holes 121 can be different from the second spraying hole 1203. The spraying holes 121 and the second spraying hole 1203 are respectively communicated with the first 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 spraying holes 121 and the second spraying hole 1203.

[0387] The mounting portion 1201 is a hollow structure and is respectively communicated with the spraying holes 121 and the first cavity 1301 of the fixing member 130, so that the spraying holes 121 are communicated with the first cavity 1301 through the mounting portion 1201.

[0388] For example, the spray head 120 can open or block the second spraying hole 1203 during the screwing process in the fixing member 130.

[0389] Since the spray head 120 is screwed in the fixing member 130, when the user needs to disassemble the spray head 120, the spraying portion 1202 can be rotated to move the mounting portion 1201 relative to the fixing member 130 to move away from one end of the fixing member 130 and be screwed out from the second fixing portion 1305, so that the connection between the spray head 120 and the fixing member 130 can be released, and the disassembly of the spray head 120 can be realized. In this way, it is convenient for the user to clean the impurities such as wire scraps in the spray head 120, prevent the spray head 120 from being blocked or the dirt on the surface of the spray head 120 from polluting the washing water, and affect the washing effect.

[0390] Referring to FIGS. 56 and 57, in some embodiments, the spraying portion 1202 is provided with a first holding portion 1204 recessed towards the spraying pipe 110, so that the user can disassemble the spray head 120 by applying a force to the first holding portion 1204. For example, the first holding portion 1204 is a recessed structure.

[0391] Referring to FIGS. 54 to 56, the second spray hole 1203 can be opened or blocked during the screwing of the spray head 120 into the fixing member 130. Thus, during the screwing of the spray head 120 into the fixing member 130, the liquid in the liquid supply line can enter the inner tub 50 through the spray hole 121 and the second spray hole 1203. Alternatively, the liquid in the liquid supply line can enter the inner tub 50 only through the spray hole 121. The spray assembly 100 can form water streams of different forms and intensities so that the user can select the type of water stream according to personal needs or the type of laundry to be cleaned.

[0392] The structure of the spray assembly 100 will be further described below by way of example with reference to the selection of the type of water stream according to the type of laundry to be cleaned.

[0393] For example, referring to FIG. 54, when the second spray hole 1203 is opened during the screwing of the spray head 120 into the fixing member 130, the liquid in the liquid supply line can enter the inner tub 50 through the spray hole 121 and the second spray hole 1203, in which case a dispersed water stream with a relatively small pressure can be formed, which is suitable for cleaning laundry requiring a gentle water stream.

[0394] For example, referring to FIG. 56, when the second spray hole 1203 is blocked during the screwing of the spray head 120 into the fixing member 130, the liquid in the liquid supply line can enter the inner tub 50 only through the spray hole 121, in which case a concentrated water stream with a relatively large pressure can be formed, which is suitable for cleaning laundry requiring a powerful water stream.

[0395] Referring to FIGS. 54 and 56, the spray head 120 can be screwed into the fixing member 130 to the open position or the blocked position.

[0396] Referring to FIG. 54, when the spray head 120 is in the open position, there is a gap between the circumferential outer wall of the spray portion 1202 and the circumferential inner wall of the open end 1302 along the circumference of the spray head 120 to open the second spray hole 1203, so that the liquid in the liquid supply line can enter the inner tub 50 through the spray hole 121 and the second spray hole 1203 to form a dispersed water stream with a relatively small pressure.

[0397] Referring to FIG. 56, when the spray head 120 is in the blocked position, the circumferential outer wall of the spray portion 1202 is in contact with the circumferential inner wall of the open end 1302 along the circumference of the spray head 120 to block the second spray hole 1203, so that the liquid in the liquid supply line can enter the inner tub 50 only through the spray hole 121 to form a concentrated water stream with a relatively large pressure.

[0398] Referring to FIG. 56, the circumferential inner wall of the opening end 1302 can be tapered, for example, the small-diameter end of the circumferential inner wall of the opening end 1302 can be directed toward the spray pipe 110, and the large-diameter end can be directed toward the inner barrel 50. The circumferential outer wall of the spray portion 1202 can be tapered to match the circumferential inner wall of the opening end 1302, for example, the circumferential outer wall of the spray portion 1202 can be tapered and have a small-diameter end and a large-diameter end.

[0399] Different from the spray assembly, when the spray head 120 is in the closed position, the circumferential outer wall of the spray portion 1202 can be in conical surface contact with the circumferential inner wall of the opening end 1302 to close the second spray hole 1203 by the cooperation of the spray portion 1202 and the opening end 1302. For example, the large-diameter end of the circumferential outer wall of the spray portion 1202 can be in conical surface contact with the circumferential inner wall of the opening end 1302.

[0400] 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 member 130, so that the user can disassemble the spray head 120.

[0401] Referring to FIGS. 54-56, when the user needs concentrated and high-pressure water flow, the spray head 120 can be rotated to be screwed toward the side close to the spray pipe 110, and in the process, the large-diameter end of the circumferential outer wall of the spray portion 1202 can move toward the side close to the spray pipe 110 to close the second spray hole 1203. When the large-diameter end of the circumferential outer wall of the spray portion 1202 contacts the circumferential inner wall of the opening end 1302 during the screwing of the spray head 120, the spray head 120 is in the closed position, and the second spray hole 1203 is closed.

[0402] Correspondingly, when the user needs to disperse and low-pressure water flow, the spray head 120 can also be rotated to move away from the side close to the spray pipe 110. In this process, the large-diameter end of the circumferential outer wall of the spray portion 1202 moves away from the side close to the spray pipe 110, and when the large-diameter end of the circumferential outer wall of the spray portion 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.

[0403] Referring to FIG. 56, in some embodiments, the spray hole 121 has a third segment 1211 and a fourth segment 1212 along the flow direction of the liquid in the spray hole 121, for example, the third segment 1211 can be in a converging structure, and the fourth segment 1212 can be in a diverging structure.

[0404] Alternatively, in some embodiments, the inner diameter of the third section 1211 and the fourth section 1212 can remain unchanged along the flow direction of the liquid in the spray hole 121.

[0405] When the third section 1211 is in a converging structure and the fourth section 1212 is in a diverging 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 increased compared to the case where the inner diameter of the third section 1211 and the fourth section 1212 remain unchanged.

[0406] For example, when the third section 1211 is in a converging structure and the fourth section 1212 is in a diverging structure along the flow direction of the liquid in the spray hole 121, the cross-sectional area of the third section 1211 decreases and the cross-sectional area of the fourth section 1212 increases. The cross-sectional area of the spray hole 121 at the third section 1211 and the fourth section 1212 is equal. The cross-section is perpendicular to the length direction of the fixing member 130 (see W direction).

[0407] Referring to FIG. 56, the inner diameter of the third section 1211 decreases and the inner diameter of the fourth section 1212 increases along the flow direction of the liquid in the spray hole 121, and the inner diameter of the third section 1211 and the fourth section 1212 at the opposite end is equal, so that the cross-sectional area of the third section 1211 decreases and the cross-sectional area of the fourth section 1212 increases.

[0408] In addition, since the inner diameter of the third section 1211 and the fourth section 1212 at the opposite end is equal, the inner diameter of the spray hole 121 can smoothly transition between the third section 1211 and the fourth section 1212, so as to ensure that the liquid can flow in the predetermined direction to the fourth section 1212. In addition, since the inner diameter of the third section 1211 and the fourth section 1212 at the opposite end is equal, the spray hole 121 forms a narrow opening between the third section 1211 and the fourth section 1212, and when the liquid flows to the narrow opening through the third section 1211, the flow of the liquid is at the critical point mentioned above.

[0409] Referring to FIG. 56, the third section 1211 can directly connect to the fourth section 1212. Alternatively, the spray hole 121 can further have a second connecting portion, and the third section 1211 and the fourth section 1212 are connected through the second connecting portion. The inner diameter of the second connecting portion is unchanged along the flow direction of the liquid in the spray hole 121, and the inner diameter of the second connecting portion is equal to the minimum inner diameter of the third section 1211 and the fourth section 1212, so that the connection between the third section 1211 and the second connecting portion and the connection between the fourth section 1212 and the second connecting portion are smoothly transitioned, so as to ensure that the liquid can flow in the predetermined direction to the fourth section 1212.

[0410] And, by the third segment 1211 directly connecting with the fourth segment 1212, or by the second connecting part connecting, the structure of the spray hole 121 can be diversified to meet the design requirements of the spray head 120 on the spray hole 121.

[0411] Compared with the setting of the second connecting part, when the third segment 1211 directly connects with the fourth segment 1212, the length of the spray hole 121 in the W direction can be reduced while increasing the pressure of the liquid and increasing the spray area, 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.

[0412] It should be noted that in some embodiments, other openings can also be provided at other positions of the spray part 1202, which can be in communication with the first cavity 1301 of the fixing part 130, and these openings can be always open or can be opened or closed to expand the spray area of the spray assembly 100.

[0413] Based on the fact that the spray hole on the spray head in the related art is usually a circular hole, the coverage area and the pressure of the mixed liquid sprayed out of the spray hole are limited, and it is difficult to efficiently wash the clothes, and the washing effect of the clothes treatment equipment needs to be improved, referring to FIG. 58, the spray assembly in some embodiments of the clothes treatment equipment of the present disclosure includes a spray head, a second moving part and a pressing part which are in communication with the water outlet end of the liquid inlet pipeline. The shape of the spray hole of the spray head is adjusted by the second moving part and the pressing part, so that the pressure of the liquid sprayed out of the spray hole can be increased, and the spray area is large, so that the liquid sprayed by the spray head to the inner drum can cover and wash the clothes in the inner drum, which is beneficial to improving the efficiency of washing clothes and improving the washing effect.

[0414] The structure of the spray assembly and the clothes treatment equipment with the second moving part and the pressing part will be further described below in combination with the drawings and embodiments.

[0415] Referring to FIG. 59, the clothes treatment equipment includes a liquid inlet pipeline 90A and a spray assembly 100. The structure of the liquid inlet pipeline 90A is described above.

[0416] In combination with FIG. 60, the spray assembly 100 includes a spray head 120, a second moving part 150 and a pressing part 160, the spray head 120 is in communication with the water outlet end of the liquid inlet pipeline 90A, and the liquid in the liquid inlet pipeline 90A is sprayed to the inner drum through the spray head 120, thereby washing the clothes in the inner drum. The spray head 120 is provided with a spray hole 121 for spraying liquid, so that the liquid in the liquid inlet pipeline 90A can be sprayed to the inner drum through the spray hole 121, thereby washing the clothes in the inner drum.

[0417] The second moving member 150 can surround the outer periphery of the shower head 120, and the second moving member 150 can reciprocate along a second direction, for example, the second direction (i.e., the Z direction in FIG. 60) is the flow direction of the liquid in the shower hole 121. In combination with FIG. 61, the extruding member 160 can be located between the shower head 120 and the second moving member 150, the shower hole 121 has a third section 1211 and a fourth section 1212, and the extruding member 160 is configured to extrude and deform the shower head 120 during the movement of the second moving member 150, so that the inner contour of the third section 1211 is in a contracted state along the second direction, and the inner contour of the fourth section 1212 is in an expanded state along the second direction.

[0418] Through the cooperation of the second moving member 150 and the extruding member 160, the cross-sectional area of the third section 1211 decreases along the flow direction of the liquid in the shower hole 121, and the cross-sectional area of the fourth section 1212 increases. The cross-sectional area of the shower hole 121 is equal at the third section 1211 and the fourth section 1212. The cross section is perpendicular to the axial direction of the shower hole 121. The axial direction of the shower hole 121 can be seen in the Z direction.

[0419] It should be understood that, in general, the flow rate of the liquid is inversely proportional to the cross-sectional area of the pipe when the liquid flows in the pipe.

[0420] The shower hole 121 can also be regarded as a kind of pipe. Since the cross-sectional area of the third section 1211 decreases along the flow direction of the liquid in the shower hole 121, the flow rate of the liquid in the third section 1211 increases during the flow of the liquid in the third section 1211. When the flow rate of the liquid increases to a critical point in the third section 1211, the flow rate will not increase again. When the flow rate of the liquid reaches the critical point, the speed of the liquid is greater than the speed of sound.

[0421] When the speed of the liquid is greater than the speed of sound, the above-mentioned inverse relationship between the flow rate of the liquid and the cross-sectional area does not apply, but is reversed. In this case, the greater the cross-sectional area, the faster the flow rate of the liquid. Since the cross-sectional area of the fourth section 1212 increases along the flow direction of the liquid in the shower hole 121, when the liquid enters the fourth section 1212, the liquid continues to accelerate and exceeds the speed of sound, so that the flow rate of the liquid increases instantaneously when the liquid is ejected through the shower hole 121. For the shower hole 121, the flow rate is proportional to the pressure, so when the flow rate of the liquid increases instantaneously, the pressure of the liquid also increases instantaneously, which can effectively flush the laundry in the inner tub 50 and improve the washing effect.

[0422] In this case, since the cross-sectional area of the fourth section 1212 gradually increases along the flow direction of the liquid in the spray hole 121, the spray area of the liquid sprayed to the inner tub 50 via the fourth section 1212 can be increased, so that the liquid sprayed to the inner tub 50 via the spray hole 121 can cover and wash the laundry in the inner tub 50 in a large area, thereby efficiently washing the laundry and improving the washing effect.

[0423] In addition, since the liquid sprayed to the inner tub 50 by the spray head 120 has a high pressure and a large spray area, and part of the door body 30 generally protrudes towards the inner tub 50, and the door seal 60 is located on the circumferential side of the protruding part of the door body 30, the liquid sprayed to the inner tub 50 by the spray head 120 can not only wash the inner tub 50 in a large area, but also wash the door body 30, the door seal 60, etc. in a larger area, so as to avoid the residues such as foam generated by the detergent remaining in the inner tub 50, the door seal 60 and the door body 30, and improve the washing effect.

[0424] When the liquid inlet pipeline 90A is a circulation pipeline, the liquid in the liquid inlet pipeline 90A is the mixed liquid in the circulation pipeline. The mixed liquid in the circulation pipeline can be sprayed to the inner tub via the spray hole 121, so that the mixed liquid can soak the laundry, help the laundry absorb the detergent in the mixed liquid, and help the detergent fully contact the stains attached to the surface of the laundry, thereby improving the washing effect.

[0425] In addition, the mixed liquid can be sprayed to the laundry by the spray head 120, and the mixed liquid can be effectively reduced to reduce the entanglement between the laundry, improve the washing effect, and protect the quality of the fabric of the laundry.

[0426] It should be noted that when the liquid inlet pipeline 90A is a circulation pipeline, water can be saved while improving the washing effect. On the basis of achieving the same washing effect, compared with the laundry treatment equipment in the related art, since the washing effect of the laundry treatment equipment of some embodiments of the present disclosure is improved, the laundry treatment equipment of some embodiments of the present disclosure also has the characteristics of saving time, saving power and reducing energy consumption.

[0427] When the liquid inlet pipe 90A is a water inlet pipe, the liquid in the liquid inlet pipe 90A is water flowing into the water inlet pipe from an external water source. The water inlet pipe includes a water inlet pipe, a water inlet valve and a water inlet pipe branch. The water inlet pipe is connected to the external water source, and the water inlet valve is arranged between the water inlet pipe and the water inlet pipe branch. The water inlet pipe branch is arranged in the housing. 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 spraying assembly 100. The water in the water inlet pipe branch can be sprayed into the inner drum through the spraying holes 121, so as to soak the laundry, help the detergent to fully contact with the stains attached to the surface of the laundry, and thus improve the washing effect. Moreover, when the water in the water pipe is sprayed into the inner drum through the spraying holes 121, the entanglement between the laundry can be effectively reduced, the washing effect is improved, and the fabric quality of the laundry is protected.

[0428] Hereinafter, the structure of the laundry treatment apparatus will be further described by taking the liquid inlet pipe 90A as an example.

[0429] Continuing to refer to FIG. 61, the spraying assembly 100 can further include a spraying pipe 110, which can include opposite first and second ends 111 and 112. The first end 111 can be connected to the water outlet end of the liquid inlet pipe 90A, and the spraying head 120, the pressing member 160 and the second moving member 150 can be connected to the second end 112 of the spraying pipe 110, respectively, and the second moving member 150 is movably connected to the second end 112 of the spraying pipe 110. For example, in the process of assembly, the spraying head 120, the pressing member 160 and the second moving member 150 can be installed on the spraying pipe 110, respectively, to form an assembly, and then the assembly is connected to the liquid inlet pipe 90A to complete the assembly of the spraying assembly 100 in the laundry treatment apparatus.

[0430] The spraying pipe 110, as a carrier of the spraying assembly 100, can provide a mounting basis for the above-mentioned components. When the spraying assembly 100 needs to be repaired, the spraying assembly 100 can be detached from the liquid inlet pipe 90A for repair, which can facilitate the installation and removal of the spraying assembly 100 in the laundry treatment apparatus, and facilitate the repair and maintenance of the spraying assembly 100.

[0431] Referring to FIG. 62, the second moving member 150 can include a second connecting portion 151, a fifth segment 152 (a transition segment) and a sixth segment 153 (a pressing segment) connected in sequence. For example, the inner diameter of the sixth segment 153 is smaller than that of the second connecting portion 151, and the inner diameter of the fifth segment 152 decreases along the second direction (i.e., the Z direction). The second connecting portion 151 is movably connected to the second end 112 of the spraying pipe 110, and the fifth segment 152 and the sixth segment 153 are configured to apply a pressing force to the pressing member 160.

[0432] For example, in combination with FIG. 63, when the second moving member 150 moves in the direction opposite to the second direction, due to the reduced inner diameter of the fifth section 152 and the inner diameter of the sixth section 153, the fifth section 152 and the sixth section 153 will extrude the extruding member 160, so that the extruding member 160 extrudes and deforms the shower head 120, and the cross-sectional area of the middle part of the shower head 120 (the middle part can be understood as the junction of the third section 1211 and the fourth section 1212) is reduced. In this way, in the second direction, the cross-sectional area of the third section 1211 is reduced, and the cross-sectional area of the fourth section 1212 is increased, so that the shower head 120 can realize the effects of increasing the pressure and increasing the spraying area.

[0433] For example, due to the reduced inner diameter of the fifth section 152, during the movement of the second moving member 150 in the direction opposite to the second direction, the extrusion amount of the fifth section 152 to the extruding member 160 is also increased. Correspondingly, the extrusion amount of the extruding member 160 to the shower head 120 is also increased, so that the inner diameter of the middle part of the spray hole 121 is reduced. For example, the inner diameter of the middle part of the spray hole 121 is different, and the adjustment effect of the water pressure and the spraying area is also different. Therefore, the second moving member 150 can be moved to different positions to make the shower head 120 spray water flow with different pressure and spraying area, which can effectively improve the flexibility of the adjustment of the shower head 120, so that the user can flexibly set according to the demand of the water pressure and the spraying area of the spray head 120.

[0434] The outer periphery of the second connecting part 151 can have a first threaded part, and the inner wall of the second end 112 of the shower pipe 110 can have a second threaded part matched with the first threaded part. For example, the first threaded part can be an external thread, and the second threaded part can be an internal thread. The second connecting part 151 and the second end 112 of the shower pipe 110 can be connected through the cooperation of the first threaded part and the second threaded part.

[0435] In this way, by rotating the second moving member 150, the second moving member 150 can be rotated and moved relative to the shower pipe 110, so as to apply an extrusion force to the extruding member 160. The threaded cooperation facilitates the control of the movement amount of the second moving member 150, so as to adjust the extrusion amount of the extruding member 160 according to the movement amount of the second moving member 150, which can effectively improve the accuracy of the adjustment of the water pressure and the spraying area at the shower head 120.

[0436] Continuing to refer to FIG. 63, the extruding member 160 can include a third connecting portion 161 (connecting ring), a fourth connecting portion 162 (connecting rod), and an extruding portion 163 (extruding head), the fourth connecting portion 162 is located between the third connecting portion 161 and the extruding portion 163, and the first end of the fourth connecting portion 162 can be connected with the third connecting portion 161, and the second end can be connected with the extruding portion 163. The third connecting portion 161 can be connected with the spray pipe 110, so that the extruding member 160 is connected with the spray pipe 110 through the third connecting portion 161. When the second moving member 150 moves in the direction opposite to the second direction, the end of the fourth connecting portion 162 connected with the extruding portion 163 can be offset towards the direction of the spray head 120, so as to drive the extruding portion 163 to extrude towards the spray head 120.

[0437] The fourth connecting portion 162 is a rod-shaped structure, which has low rigidity and strength and is easy to deform. During the movement of the second moving member 150, as the force applied by the second moving member 150 to the extruding portion 163 increases, the fourth connecting portion 162 can be offset, so that the extruding portion 163 can move towards the spray head 120, so that the extruding portion 163 can extrude the spray head 120, so that the cross section of the middle part of the spray head 120 is extruded and reduced, and the inner diameter of the third section 1211 of the spray head 120 is reduced, and the inner diameter of the fourth section 1212 is increased.

[0438] Continuing to refer to FIG. 63, the extruding member 160 can include two fourth connecting portions 162 and two extruding portions 163, the two fourth connecting portions 162 can be located on the two sides of the spray head 120 respectively, and the two extruding portions 163 are connected with the two fourth connecting portions 162 respectively. In this way, during the movement of the second moving member 150, the extruding portions 163 located on the two sides of the spray head 120 can extrude the spray head 120 from both sides respectively, so that the spray head 120 can be simultaneously reduced from both sides, so as 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 is more uniform after passing through the spray head 120, which helps to improve the spraying effect of the spray head 120.

[0439] Continuing to refer to FIG. 63, the spray assembly 100 can further include a supporting member 130A connected with the spray pipe 110, and the spray head 120 can be sleeved on the outer periphery of the supporting member 130A. The supporting member 130A can support and fix the spray head 120, so as to reduce or avoid the deformation or falling of the spray head 120.

[0440] For example, referring to FIGS. 64 and 65, the support 130A can include a first support portion 131A (a first support ring) and a second support portion 132A (a second support ring) arranged at intervals, and a third support portion 133A can be arranged between the first support portion 131A and the second support portion 132A. The first support portion 131A can be connected to the second end 112 of the spray pipe 110, so that the support 130A can be connected to the spray pipe 110 through the first support portion 131A. In combination with FIG. 63, the two ends of the spray head 120 are connected to the first support portion 131A and the second support portion 132A respectively, so as to realize the installation and fixation of the spray head 120.

[0441] The third support portion 133A can play a fixing role in the axial direction (i.e., the second direction) of the spray head 120, and the first support portion 131A and the second support portion 132A can play a supporting role in the circumferential direction of the spray head 120, so as to support the spray head 120 and make the spray head 120 have a passage for water flow.

[0442] Continuing to refer to FIG. 64, the outer periphery of the first support portion 131A can be surrounded by a third fixing portion 1311A (a first boss), and the outer periphery of the second support portion 132A can be surrounded by a fourth fixing portion 1321A (a second boss). In combination with FIG. 65, the two ends of the spray head 120 can be sleeved on the outer periphery of the third fixing portion 1311A and the fourth fixing portion 1321A respectively. The third fixing portion 1311A and the fourth fixing portion 1321A can limit and fix the two ends of the spray head 120, which can effectively reduce or avoid the two ends of the spray head 120 from falling off the first support portion 131A and the second support portion 132A, and improve the reliability and firmness of the connection between the spray head 120 and the first support portion 131A and the second support portion 132A.

[0443] For example, the support 130A includes two third support portions 133A, which can be close to the two sides of the spray head 120 respectively, and the connecting line between the two third support portions 133A is perpendicular to the connecting line between the two extrusion portions 163. For example, the two third support portions 133A are arranged opposite to each other along the first radial direction of the spray head 120, and the two extrusion portions 163 are arranged opposite to each other along the second radial direction of the spray head 120, and the first radial direction is perpendicular to the second radial direction. In this way, the interference between the third support portion 133A and the extrusion portion 163 can be avoided, and the extrusion of the extrusion portion 163 on the spray head 120 is not affected, which helps to improve the reliability and stability of the extrusion of the extrusion member 160 on the spray head 120.

[0444] The spray head in the related art is fixed on the laundry treating apparatus, and the spray area of the spray head is small, which can not spray to the washing water, resulting in that the detergent foam or other impurities can be left on the inner drum, the door seal and the door body. After a long time, the impurities can be mildewed and smelly.

[0445] To solve the above problems, the laundry treating apparatus of some embodiments of the present disclosure is provided with a movable assembly, which can move under the power provided by the liquid flowing in the spray pipe, so that the movable assembly can drive the spray head to swing. In this way, through the swing of the spray head, the spray area can be expanded, so that the inner drum, the door seal and the door body can be washed to avoid the detergent foam and other impurities left on the inner drum, the door seal and the door body, which is beneficial to improve the washing effect.

[0446] Hereinafter, the structure of the laundry treating apparatus will be further described taking the liquid inlet pipeline as the circulation pipeline 90 as an example.

[0447] Referring to FIG. 66, the laundry treating apparatus can further include a communication device 200. The communication device 200 is arranged in the housing 20. The communication device 200 can selectively communicate the water outlet end of the drainage pump 70 with the water inlet end of the circulation pipeline 90 and the water inlet end of the drainage pipe 80.

[0448] The spray pipe 110 can be fixedly connected with the water outlet end of the circulation pipeline 90 by clamping, threaded connection, welding or the like, and is in communication with the water outlet end of the circulation pipeline 90. The spray pipe 110 can pass through the door seal 60 and be fixed on the door seal 60, and the water outlet end of the spray pipe 110 can be bent towards the inner drum 50 relative to the rest of the spray pipe 110.

[0449] In some embodiments, referring to FIG. 67, the spray pipe 110 includes a first section 113 and a second section 114, the first section 113 and the second section 114 are connected, the first section 113 is connected with the water outlet end of the circulation pipeline 90, the first section 113 passes through the door seal 60 and is fixed on the door seal 60, and the water outlet end of the second section 114 is towards the inner drum 50.

[0450] The spray pipe 110 further includes a mounting cover 170. One side of the first section 113 close to the second section 114 is provided with a mounting port, and the mounting cover 170 is detachably mounted on the mounting port to block the mounting port. The mounting cover 170 is schematically shown by a dashed line in FIGS. 68-70.

[0451] Referring to FIG. 68, the spray head 120 is rotatably mounted on the water outlet end of the spray pipe 110. For example, the spray head 120 is rotatably mounted on the water outlet end of the second section 114 of the spray pipe 110. The liquid in the circulation pipeline 90 is sprayed to the inner drum 50 through the spray pipe 110 and the spray head 120.

[0452] The spray head 120 is provided with a first rotating shaft 121A (a rotating shaft). The first rotating shaft 121A is rotationally connected to the second section 114 of the spray pipe 110. The spray head 120 can swing relative to the water outlet end of the second section 114 through the first rotating shaft 121A.

[0453] The spray head 120 is at least partially mounted inside the second section 114. For example, most of the spray head 120 is mounted inside the second section 114, so that the spray head 120 can be prevented from being deformed or falling off due to friction or extrusion of laundry and the like.

[0454] Since the spray pipe 110 is provided through and fixed to the door seal 60, the water outlet end of the second section 114 faces the inner drum 50. By arranging the spray head 120 at the water outlet end of the second section 114 of the spray pipe 110, the spray head 120 can be located on the side of the door seal 60 facing the inner drum, and the liquid in the spray pipe 110 can be sprayed into the inner drum 50 through the spray head 120, so that the user can observe the spraying effect of the spray head 120 through the door body 30.

[0455] Referring to FIG. 68, the laundry treating apparatus further includes a moving assembly (a first moving assembly). The moving assembly is mounted on the spray pipe 110. The moving assembly is connected to the spray head 120. The moving assembly is movable under the action of the liquid flowing in the spray pipe 110, so as to swing the spray head 120.

[0456] Some embodiments of the present disclosure provide a laundry treating apparatus. The liquid flowing in the spray pipe 110 acts on the moving assembly, so that the moving assembly moves, and the moving assembly swings the spray head 120, so as to expand the spraying area of the spray head 120, so that the inner drum 50, the door seal 60, and the door body 30 are effectively washed, and residues such as foam generated by the detergent are prevented from being left on the inner drum 50, the door seal 60, and the door body 30, so as to improve the washing effect.

[0457] In some embodiments, referring to FIG. 68, the moving assembly can include a rotating piece 160A. The rotating piece 160A is rotationally arranged in the spray pipe 110. The moving assembly is configured to move when the liquid in the spray pipe 110 acts on the rotating piece 160A.

[0458] For example, the rotating piece 160A can include a rotating body 161A and a plurality of blades 162A. The plurality of blades 162A are arranged on the rotating body 161A along the circumference of the rotating piece 160A.

[0459] The rotating body 161A includes a second rotating shaft 1611. A first end of the second rotating shaft 1611 is rotationally connected to an inner wall of the first section 113 of the spray pipe 110, and a second end of the second rotating shaft 1611 is rotationally connected to an inner wall of the mounting cover 170. The inner wall of the mounting cover 170 refers to a side wall of the mounting cover 170 facing the inside of the spray pipe 110.

[0460] The rotating member 160A can rotate about an axis of the second rotating shaft 1611. The second rotating shaft 1611 can be horizontally placed. The axis of the second rotating shaft 1611 can be parallel to the door body 30. The axis of the second rotating shaft 1611 can extend in a direction perpendicular to the swinging direction of the spray head 120, so as to swing the spray head 120 towards the upper side and the lower side of the laundry treatment apparatus 10. The upper side of the laundry treatment apparatus 10 refers to a side where the top of the laundry treatment apparatus 10 is located when the laundry treatment apparatus 10 is in use. The lower side of the laundry treatment apparatus 10 refers to a side where the bottom of the laundry treatment apparatus 10 is located when the laundry treatment apparatus 10 is in use.

[0461] When the rotating member 160A is installed, the mounting cover 170 is detached from the first section 113 of the spray pipe 110, and then the rotating member 160A is installed into the first section 113 through the installation opening of the first section 113, and finally the mounting cover 170 is installed on the first section 113. The rotating member 160A is installed through the installation opening of the first section 113, so that the installation of the rotating member 160A is facilitated. Moreover, the mounting cover 170 can seal the installation opening, so as to prevent the liquid in the spray pipe 110 from leaking from the installation opening.

[0462] In some embodiments, when the drain pump 70 pumps the mixed liquid in the inner tub 50 and the outer tub 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, so that the rotating member 160A rotates.

[0463] Referring to FIG. 68, the rotating member 160A can rotate in the counterclockwise direction (i.e., the -W direction). In other embodiments, the rotating member 160A can also rotate in the clockwise direction (i.e., the +W direction). The -W direction is the opposite direction of the +W direction.

[0464] Referring to FIG. 68, the movable assembly can further include a transmission member 190 (moving rod) located in the spray pipe 110 and a second reset member 180. The transmission member 190 is fixedly connected to the spray head 120. The second reset member 180 is connected between the transmission member 190 and the spray pipe 110. The transmission member 190 drives the spray head 120 to swing under the action of the rotating member 160A and the second reset member 180.

[0465] For example, the transmission member 190 can be fixed to the spray head 120 by means of clamping, threaded connection, welding, etc.

[0466] For example, the transmission member 190 can drive the spray head 120 to oscillate around the axis of the first rotation axis 121A.

[0467] For example, a first portion of the transmission member 190 is located in the second section 114 of the spray pipe 110, and the first portion is fixedly connected with the spray head 120; a second portion of the transmission member 190 extends into the first section 113. For example, the plurality of blades 162A of the rotating member 160A sequentially contact the second portion of the transmission member 190 located in the first section 113 during rotation of the rotating member 160A.

[0468] The second reset member 180 can be a tension spring. A first end of the tension spring is connected with the second section 114 of the spray pipe 110, and a second end of the tension spring is connected with the transmission member 190.

[0469] In FIG. 68, a first state of the spray head 120 is a state of the tension spring and the transmission member 190 when the tension spring and the transmission member 190 are in initial states, and the transmission member 190 is not in contact with the blade 162A during oscillation of the spray head 120 driven by the movable assembly. In some embodiments, when the drain pump 70 pumps the mixture in the inner cylinder 50 and the outer cylinder 40 into the circulation pipeline 90, the mixture 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, and the blade 162A is not in contact with the transmission member 190. The tension spring and the transmission member 190 are in initial states.

[0470] In FIG. 69, a second state of the spray head 120 is a state of the transmission member 190 when the blade 162A of the rotating member 160A drives the transmission member 190 to rotate in the +W direction, and the tension spring is stretched during oscillation of the spray head 120 driven by the movable assembly. In some embodiments, when the drain pump 70 pumps the mixture in the inner cylinder 50 and the outer cylinder 40 into the circulation pipeline 90, the mixture 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. The blade 162A of the rotating member 160A drives the transmission member 190 to rotate in the +W direction, and the tension spring is stretched.

[0471] In FIG. 70, a third state of the spray head 120 is a state of the transmission member 190 when the transmission member 190 rotates to a limit position in the +W direction during oscillation of the spray head 120 driven by the movable assembly. In some embodiments, when the drain pump 70 pumps the mixture in the inner cylinder 50 and the outer cylinder 40 into the circulation pipeline 90, the mixture 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. The transmission member 190 rotates to a limit position in the +W direction. As the rotating member 160A continues to rotate, the blade 162A is out of contact with the transmission member 190.

[0472] When the transmission member 190 is out of contact with the vane 162A, the transmission member 190 rotates in the -W direction under the tension of the tension spring and returns to the initial state. For example, the shower head 120 swings from the third state to the first state. It should be noted that the vane 162A of the rotating member 160A is not in contact with the transmission member 190 when the transmission member 190 returns to the initial state. When the next vane 162A of the rotating member 160A again pushes the transmission member 190 after the transmission member 190 returns to the initial state, the transmission member 190 repeats the above process, and the transmission member 190 swings back and forth in the +W direction and the -W direction.

[0473] In FIG. 68, the position of the transmission member 190 is the limit position of the transmission member 190 rotating in the -W direction under the tension of the tension spring. In FIG. 70, the position of the transmission member 190 is the limit position of the transmission member 190 rotating in the +W direction under the tension of the tension spring and the vane 162A of the rotating member 160A. The transmission member 190 swings back and forth between the two limit positions, and the transmission member 190 drives the shower head 120 to swing back and forth, so that the spraying area of the shower head 120 can be expanded, and the inner drum 50, the door seal 60, and the door body 30 can be effectively washed.

[0474] Referring to FIG. 71, in some embodiments, the shell 20, the inner drum 50, the outer drum 40, the door body 30, the door seal 60, the drain pump 70, the drain pipe 80, the circulation pipeline 90, the spray pipe 110, and the shower head 120 of the laundry treating apparatus 10 are the same as those in the above embodiments, and will not be described herein.

[0475] The laundry treating apparatus 10 can include a movable assembly (second movable assembly). The movable assembly is installed on the spray pipe. The movable assembly is connected to the shower head 120. The movable assembly can move under the power provided by the liquid flowing in the spray pipe 110. The movable assembly can drive the shower head 120 to swing.

[0476] Referring to FIGS. 72 and 73, the movable assembly can include a rotating member 160A. The rotating member 160A is rotatably arranged 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.

[0477] For example, referring to FIG. 73, the rotating member 160A can include a rotating body 161A and a plurality of vanes 162A. The plurality of vanes 162A are sequentially arranged on the rotating body 161A along the circumferential direction of the rotating member 160A.

[0478] The rotating body 161A can have a second rotating shaft 1611. A first end of the second rotating shaft 1611 is rotationally connected to an inner wall of the first section 113 of the spray pipe 110. A second end of the second rotating shaft 1611 penetrates the mounting cover 170 and is rotationally connected to the mounting cover 170, for example, a portion of the second rotating shaft 1611 is exposed outside the spray pipe 110.

[0479] The second rotating shaft 1611 can be horizontally placed. An axis of the second rotating shaft 1611 can be parallel to the door body 30. An extending direction of the axis of the second rotating shaft 1611 can be perpendicular to a swinging direction of the spray head 120, so that the spray head 120 swings towards the upper side and the lower side of the laundry treatment apparatus 10. The upper side of the laundry treatment apparatus 10 refers to a side where a top of the laundry treatment apparatus 10 is located when the laundry treatment apparatus 10 is used. The lower side of the laundry treatment apparatus 10 refers to a side where a bottom of the laundry treatment apparatus 10 is located when the laundry treatment apparatus 10 is used.

[0480] The movable assembly can further include a connecting member 163A outside the spray pipe 110. The connecting member 163A is connected to a portion of the second rotating shaft 1611 of the rotating member 160A outside the spray pipe 110, so that the connecting member 163A can rotate with the rotation of the second rotating shaft 1611.

[0481] The connecting member 163A can be a circular connecting plate. The connecting member 163A can be fixed to the second rotating shaft 1611 by clamping, threaded connection, welding, or the like.

[0482] 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 second rotating shaft 1611.

[0483] In some embodiments, when the drain pump 70 pumps the mixture in the inner drum 50 and the outer drum 40 into the circulation pipeline 90, the mixture 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, so that the rotating member 160A rotates in the counterclockwise direction (i.e., the -W direction), thereby causing the second rotating shaft 1611 to rotate the connecting member 163A, and the connecting member 163A rotates the connecting shaft 1631 around the axis of the second rotating shaft 1611.

[0484] Referring to FIGS. 72 and 74, the movable assembly can further include a transmission member 190 outside the spray pipe 110. A first end of the transmission member 190 is fixedly connected to the spray head 120. A second end of the transmission member 190 is movably connected to the connecting member 163A. The transmission member 190 swings the spray head 120 under the action of the connecting member 163A.

[0485] The first rotating shaft 121A of the spray head 120 penetrates the second section 114 of the spray pipe 110 and is rotationally connected to the second section 114 of the spray pipe 110. For example, a first part of the first rotating shaft 121A is located outside the spray pipe 110, and a second part of the first rotating shaft 121A is located outside the spray pipe 110.

[0486] The transmission member 190 can be fixed on the part of the first rotating shaft 121A located outside the spray pipe 110 by clamping, threaded connection, welding, or the like. It should be noted that in some embodiments, the transmission member 190 can also be provided with the first rotating shaft, and the spray head 120 does not need to be provided with the first rotating shaft. The first rotating shaft of the transmission member 190 penetrates the spray pipe 110 and is rotationally connected to the spray pipe 110, and then is connected to the spray head 120.

[0487] For example, the transmission member 190 can drive the spray head 120 to swing around the axis of the first rotating shaft 121A.

[0488] For example, the transmission member 190 can be provided with a movable part 1901. The connecting shaft 1631 can be movably arranged in the movable part 1901.

[0489] For example, the movable part 1901 can be a movable hole or a movable slot. For example, the movable part 1901 is a long strip-shaped movable hole, and the end of the movable hole is circular.

[0490] The dashed lines in FIGS. 72, 75, 76, and 77 are schematic views of the inside of the spray pipe 110.

[0491] In FIG. 72, the transmission member 190 is located at a first position. The first position is the position of the transmission member 190 when the connecting shaft 1631 of the connecting member 163A starts to drive the transmission member 190 to rotate around the axis of the first rotating shaft 121A in the -W direction. In some embodiments, when the drain pump 70 pumps the mixed liquid in the inner cylinder 50 and the outer cylinder 40 into the circulating pipeline 90, the mixed liquid in the circulating 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 blades 162A to rotate. The second rotating shaft 1611 rotates the connecting member 163A around the axis of the second rotating shaft 1611 in the counterclockwise direction. The connecting shaft 1631 provides a force to the transmission member 190 to rotate in the -W direction, and under the action of the force, the transmission member 190 starts to rotate in the -W direction.

[0492] In FIG. 75, the position of the transmission member 190 is a position during the rotation of the transmission member 190 in the -W direction by the connecting shaft 1631 of the connecting member 163A around the axis of the first rotating shaft 121A. For example, the position of the transmission member 190 is a position during the swing of the transmission member 190 from the first position to the second position. In some embodiments, during the rotation of the transmission member 190 in the -W direction by the connecting shaft 1631, the connecting shaft 1631 moves in the movable portion 1901 and abuts against the side wall of the movable portion 1901 to provide a force for the rotation of the transmission member 190 in the -W direction, and the transmission member 190 rotates in the -W direction under the action of the force until the second position, and the transmission member 190 drives the shower head 120 to swing in the -W direction.

[0493] In FIG. 76, the position of the transmission member 190 is the second position. The second position is a position when the transmission member 190 starts to rotate in the +W direction by the connecting shaft 1631 of the connecting member 163A around the axis of the first rotating shaft 121A. In some embodiments, when the mixed liquid in the inner cylinder 50 and the outer cylinder 40 is pumped into the circulating pipeline 90 by the drain pump 70, the mixed liquid in the circulating pipeline 90 enters the spray pipe 110. The liquid in the spray pipe 110 impacts the blades 162A of the rotating member 160A, and the blades 162A rotate. The second rotating shaft 1611 rotates in the counterclockwise direction with the connecting member 163A around the axis of the second rotating shaft 1611. The connecting shaft 1631 provides a force for the rotation of the transmission member 190 in the +W direction, and the transmission member 190 starts to rotate in the +W direction under the action of the force.

[0494] In FIG. 77, the position of the transmission member 190 is a position during the rotation of the transmission member 190 in the +W direction by the connecting shaft 1631 of the connecting member 163A around the axis of the first rotating shaft 121A.
