Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clothes processing, and in particular to a clothes processing device. BACKGROUND

[0002] At present, when clothes are washed by using a washing machine, in order to mix the detergent and water sufficiently, so as to effectively clean the clothes, a liquid storage box for receiving or storing the detergent is usually arranged on the washing machine, and the liquid storage box is connected with a water inlet pipeline of the washing machine. When water is fed into the washing machine, the liquid storage box delivers the detergent to the water inlet pipeline, so that the water in the water inlet pipeline can be mixed with the detergent before entering the drum, and the water mixed with the detergent enters the drum to clean the clothes in the drum.

[0003] In a related design, a drawer type liquid storage box is arranged on the box body of the washing machine. Before washing the clothes, the user needs to pull out the liquid storage box to add the detergent, and then reset the liquid storage box after adding the detergent. Then, the clothes to be washed are put into the drum. In this way, the whole operation process is relatively complicated, and the drawer type liquid storage box will damage the integrity of the appearance of the washing machine. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a clothes processing device, which can simplify the operation process of the user when washing clothes, and can make the overall appearance of the clothes processing device more tidy.

[0010] a liquid storage box, the liquid storage box being arranged in the receiving chamber, the liquid storage box being connected to the drum, the liquid storage box being used for containing the detergent to deliver the detergent to the drum;

[0011] a door body, the door body being rotatably arranged on the front side plate;

[0012] the front side plate is provided with:

[0013] a feeding opening, the feeding opening being arranged in correspondence with the drum and being in communication with the drum, the feeding opening being configured to put or take out the clothes into or from the drum, and the door body being capable of opening or closing the feeding opening;

[0014] A feeding opening is arranged corresponding to the liquid storage box and is in communication with the liquid storage box, and the feeding opening is configured to add detergent to the liquid storage box through the feeding opening.

[0015] When the door body opens the feeding opening, the feeding opening is opened, and when the door body closes the feeding opening, the feeding opening is covered.

[0016] By rotating the door body, the feeding opening can be opened when the feeding opening is opened, so that the user can put the clothes to be washed through the feeding opening and add detergent to the inside of the liquid storage box through the feeding opening, without the need for separate operation of the liquid storage box, reducing the user's operation. After completing the clothes feeding and detergent feeding, when the user closes the feeding opening, the feeding opening can be covered by the door body, realizing the hidden design of the feeding opening, improving the appearance integration of the clothes processing device. It can be seen that the clothes processing device of the present application not only simplifies the user's operation process of washing clothes, but also makes the appearance of the clothes processing device more simple and beautiful.

[0017] In a possible implementation, the front side plate is provided with a recessed portion recessed relative to the front side plate, and when the door body covers the feeding opening and the feeding opening, the door body is at least partially embedded in the recessed portion.

[0018] By providing a recessed portion on the front side plate and embedding the door body at least partially in the recessed portion when the door body covers the feeding opening and the feeding opening, the protrusion of the door body relative to the front side plate can be reduced, which helps to realize the miniaturization design of the clothes processing device and is also conducive to improving the flatness of the overall appearance of the clothes processing device, making the appearance of the clothes processing device more beautiful.

[0019] In a possible implementation, the recessed portion includes:

[0020] a bottom wall portion;

[0021] a side wall portion arranged around the bottom wall portion;

[0022] The feeding opening is arranged on the bottom wall portion, the feeding opening is arranged on the side wall portion, and the opening direction of the feeding opening and the opening direction of the feeding opening intersect.

[0023] By arranging the feeding opening and the feeding opening on the bottom wall portion and the side wall portion of the recessed portion, respectively, it is possible to avoid occupying the setting space of the feeding opening when arranging the feeding opening, so that the feeding opening has sufficient setting space, facilitating the user to put or take out the clothes, and it is also possible to avoid increasing the area of the door body for covering the feeding opening and the feeding opening, thereby helping to realize the miniaturization design of the clothes processing device. In addition, the opening direction of the feeding opening and the opening direction of the feeding opening intersect, which can reduce the difficulty of the user adding detergent through the feeding opening.

[0024] In a possible implementation, the bottom wall portion is provided with a recessed groove corresponding to the feeding opening, the recessed groove being recessed towards the receiving chamber relative to the bottom wall portion.

[0025] The recessed groove is arranged on the bottom wall portion, so that a larger operation space is formed at the position corresponding to the feeding opening, facilitating the user to add detergent to the liquid storage box through the feeding opening.

[0026] In a possible implementation, the drum comprises:

[0027] A first sub-drum is arranged in the receiving chamber;

[0028] A second sub-drum is arranged in the receiving chamber and is arranged in a spaced manner with the first sub-drum;

[0029] The feeding opening comprises:

[0030] A first sub-feeding opening is arranged in a corresponding manner with the first sub-drum and is in communication with the first sub-drum;

[0031] A second sub-feeding opening is arranged in a corresponding manner with the second sub-drum and is in communication with the second sub-drum, and is arranged in a spaced manner with the first sub-feeding opening;

[0032] The feeding opening is arranged between the first sub-feeding opening and the second sub-feeding opening.

[0033] The feeding opening is arranged between the first sub-feeding opening and the second sub-feeding opening, so that the liquid storage box is arranged in a corresponding manner between the first sub-feeding opening and the second sub-feeding opening, which facilitates the symmetric or approximately symmetric arrangement of the pipeline between the liquid storage box and the first sub-drum and the second sub-drum, and reduces the internal layout difficulty of the clothes treatment device.

[0034] In a possible implementation, the first sub-drum and the second sub-drum are arranged in a spaced manner along the horizontal direction, the first sub-feeding opening and the second sub-feeding opening are arranged in a spaced manner along the horizontal direction, and the feeding opening is arranged between the first sub-feeding opening and the second sub-feeding opening along the horizontal direction.

[0035] The first sub-drum and the second sub-drum are arranged in a spaced manner along the horizontal direction, which can reduce the height of the center of gravity of the clothes treatment device, thereby facilitating the improvement of the stability of the clothes treatment device. The feeding opening is arranged between the first sub-feeding opening and the second sub-feeding opening, and the first sub-feeding opening and the second sub-feeding opening are symmetrically arranged about the feeding opening, so that the appearance of the clothes treatment device is more beautiful, and the pipeline inside the clothes treatment device can be arranged in a symmetric form with the position of the feeding opening as a reference, which facilitates the reduction of the arrangement difficulty of the internal pipeline.

[0036] In a possible implementation, the liquid storage box is arranged between the first sub-drum and the second sub-drum in the horizontal direction, and is arranged below the first sub-drum and the second sub-drum in the height direction of the box body.

[0037] By arranging the liquid storage box at the position between the first sub-drum and the second sub-drum, the space inside the clothes treatment device can be effectively utilized, the integration of the clothes treatment device is improved, and the miniaturization design of the clothes treatment device is facilitated.

[0038] In a possible implementation, the drum includes:

[0039] The first sub-drum is arranged in the accommodation chamber;

[0040] The second sub-drum is arranged in the accommodation chamber and is arranged in a spaced manner with the first sub-drum;

[0041] The feeding port includes:

[0042] The first sub-feeding port is arranged in a corresponding manner with the first sub-drum and is in communication;

[0043] The second sub-feeding port is arranged in a corresponding manner with the second sub-drum and is in communication, and is arranged in a spaced manner with the first sub-feeding port;

[0044] The feeding port includes:

[0045] The first sub-feeding port is arranged in a corresponding manner with the first sub-feeding port, and the first sub-feeding port is in communication with the liquid storage box;

[0046] The second sub-feeding port is arranged in a corresponding manner with the second sub-feeding port, and the second sub-feeding port is in communication with the liquid storage box.

[0047] By arranging the first sub-feeding port and the second sub-feeding port in a corresponding manner with the first sub-drum and the second sub-drum respectively, and connecting the first sub-feeding port and the second sub-feeding port with the liquid storage box, even if one of the first sub-drum or the second sub-drum is executing a washing program, and the other is on standby, when the other is needed for washing, the detergent can be directly added through the sub-feeding port corresponding to the standby sub-drum, without the need to pause the running sub-drum, and without the need to wait for the completion of the washing of the running sub-drum, the time of the user can be saved, and the flexibility of the user in washing operation is improved.

[0048] In a possible implementation, the clothes treatment device further includes:

[0049] A cover member is connected to the front plate and at least partially embedded in the feeding opening. The cover member is used to cover the feeding opening.

[0050] By arranging the cover member in the feeding opening, dust and other sundries can be prevented from entering the liquid storage box through the feeding opening when the door body is opened, so that the liquid storage box can be prevented from being contaminated or blocked. The cover member is at least partially embedded in the feeding opening, so that the protrusion of the cover member relative to the feeding opening can be reduced, and thus the interference with the closing of the door body can be reduced.

[0051] In a possible implementation, the liquid storage box comprises:

[0052] A first sub-liquid storage box is arranged in the accommodation chamber and connected to the roller. The first sub-liquid storage box is used to contain a first type of detergent and deliver the first type of detergent to the roller.

[0053] A second sub-liquid storage box is arranged in the accommodation chamber and spaced apart from the first sub-liquid storage box. The second sub-liquid storage box is used to contain a second type of detergent and deliver the second type of detergent to the roller.

[0054] By arranging two sub-liquid storage boxes and spacing apart the two sub-liquid storage boxes, different sub-liquid storage boxes can be used to store different laundry treatment agents. For example, the first sub-liquid storage box can be used to store laundry detergent, and the second sub-liquid storage box can be used to store softener. After the laundry is cleaned with the laundry detergent, the softener can be used to care for the laundry.

[0055] In a possible implementation, the laundry treatment device further comprises a feeding assembly arranged in the accommodation chamber.

[0056] The feeding assembly comprises:

[0057] A feeding pump is connected to the liquid storage box. The feeding pump is used to extract the detergent in the liquid storage box.

[0058] A liquid delivery pipe is connected to the other end of the feeding pump. The liquid delivery pipe is used to deliver the detergent.

[0059] A liquid mixing pipe is connected to the other end of the liquid delivery pipe. The other end of the liquid mixing pipe is used to connect to a water inlet pipeline of the laundry treatment device. The liquid mixing pipe is used to mix the detergent and water flow.

[0060] By the dispensing assembly, when the clothes treatment device is filled with water, the dispensing pump can draw the detergent in the liquid storage box and deliver to the mixing pipe through the liquid delivery pipe, the mixing pipe is communicated with the water inlet pipeline, the detergent is mixed with water flow in the mixing pipe and then enters the drum, which can mix the detergent with water before entering the drum, improve the dispersity of the detergent and thus improve the washing effect.

[0061] In a possible implementation, the mixing pipe comprises:

[0062] a reduced diameter section connected to the other end of the liquid delivery pipe;

[0063] a first main section, one end of the first main section is connected to the drum, and the other end of the first main section is connected to the reduced diameter section;

[0064] a second main section, one end of the second main section is connected to the reduced diameter section, and the other end of the second main section is used for connecting the water inlet pipeline, and the inner diameter of the reduced diameter section is smaller than the inner diameters of the first main section and the second main section.

[0065] The inner diameter of the middle part of the mixing pipe is set to be smaller than the inner diameters of the two ends, when the water flow of the water inlet pipeline enters the mixing pipe, due to the Venturi effect, the flow rate of the water flow in the reduced diameter section is greater than the flow rates of the water flow in the first main section and the second main section, which can improve the mixing efficiency of the detergent and the water flow. In addition, due to the greater flow rate of the water flow in the reduced diameter section, the pressure is smaller, and a pressure difference is formed with the inside of the liquid delivery pipe, which helps to suck out the detergent in the liquid delivery pipe, avoiding the detergent remaining in the liquid delivery pipe to cause blockage.

[0066] In a possible implementation, the inner diameters of the first main section and the second main section are D1, the inner diameter of the reduced diameter section is D2, and D1 and D2 satisfy the following relationship:

[0067] 0.3D1<D2<0.7D1.

[0068] When 0.3D1D2<0.7D1, the inner diameter of the reduced diameter section can be effectively reduced to significantly increase the flow velocity of the water flow in the reduced diameter section, and the reduced diameter section can have sufficient unit flow to avoid low water inlet efficiency due to the small cross-sectional area of the reduced diameter section. When 0.3D1>D2, the inner diameter of the reduced diameter section is too small, which directly leads to a significant reduction in the flow area of the reduced diameter section, resulting in low water inlet efficiency of the water inlet pipeline. In addition, according to Poiseuille's law, the flow velocity of the water flow in the reduced diameter section will significantly increase due to the reduction in the inner diameter of the reduced diameter section, which in turn increases the resistance of the water flow in the reduced diameter section. The water inlet pump needs to drive the water flow to overcome the resistance of the reduced diameter section, which also increases the load of the water inlet pump to some extent. When D2 is greater than 0.7D1, the inner diameter of the reduced diameter section is reduced by a smaller amount compared to the inner diameters of the first main section and the second main section. As a result, the flow velocity of the water flow in the reduced diameter section does not significantly increase compared to the flow velocities of the water flow in the first main section and the second main section, and the pressure difference between the infusion tube and the reduced diameter section is relatively small. The extraction efficiency of the detergent in the infusion tube is also reduced, and the mixing efficiency of the detergent and the water flow cannot be effectively improved.

[0069] In a possible implementation, the infusion tube is provided with a flow limiting portion, and the flow limiting portion is located in the mixing tube and radially contracts to form a first flow limiting opening in the infusion direction of the infusion tube.

[0070] The end portion of the mixing tube connected with the infusion tube is radially contracted to form a second flow limiting opening.

[0071] By providing the flow limiting portion in the infusion tube, the flow limiting portion is radially contracted in the infusion direction to form the first flow limiting opening, which can prevent the water in the mixing tube from flowing back to the delivery pump or even the liquid storage box. By radially contracting the end portion of the mixing tube connected with the infusion tube to form the second flow limiting opening, the anti-backflow effect of the infusion tube can be further improved.

[0072] In a possible implementation, the drum includes:

[0073] A first sub-drum is arranged in the accommodation chamber.

[0074] A second sub-drum is arranged in the accommodation chamber and spaced apart from the first sub-drum.

[0075] The delivery opening includes:

[0076] A first sub-delivery opening is arranged in correspondence with the first sub-drum and is in communication with the first sub-drum.

[0077] A second sub-delivery opening is arranged in correspondence with the second sub-drum and is in communication with the second sub-drum, and is spaced apart from the first sub-delivery opening.

[0078] The feeding port is arranged between the first sub-feeding port and the second sub-feeding port.

[0079] The mixed liquid pipe comprises:

[0080] The first sub-mixed liquid pipe is connected to the liquid conveying pipe at one end and connected to the first sub-drum at the other end.

[0081] The second sub-mixed liquid pipe is connected to the liquid conveying pipe at one end and connected to the second sub-drum at the other end.

[0082] By adding mixed liquid pipes and making the mixed liquid pipes all communicate with the liquid conveying pipe, the washing demand of the multi-drum clothes processing device can be met through a relatively simple pipeline layout without the need to increase the feeding pump and the liquid conveying pipe, and without the need to increase the liquid storage box.

[0083] In a second aspect, the present application provides a clothes processing device, which comprises:

[0084] A cabinet comprises:

[0085] A front side plate;

[0086] A main frame, the front side plate being connected to the main frame and enclosing a receiving cavity with the main frame;

[0087] A drum arranged in the receiving cavity;

[0088] A liquid storage box arranged in the receiving cavity, the liquid storage box being connected to the drum and used for containing a detergent to deliver the detergent to the drum;

[0089] A door body rotatably arranged on the front side plate;

[0090] The front side plate is provided with:

[0091] A feeding port arranged in correspondence with and in communication with the drum, the feeding port being configured to feed or take out clothes in the drum;

[0092] A feeding port arranged in correspondence with and in communication with the liquid storage box, the feeding port being configured to add a detergent to the liquid storage box through the feeding port;

[0093] A horizontal plane passing through the center of the drop opening is a first reference plane; in the height direction of the box, the drop opening is arranged below the first reference plane, when the door body opens the drop opening, the drop opening is opened, when the door body closes the drop opening, the drop opening is covered.

[0094] By rotating the door body, when the drop opening is opened, the drop opening can be opened, so that the user can put the clothes to be washed through the drop opening, and add the detergent to the inside of the liquid storage box through the drop opening, without separate operation of the liquid storage box, reducing the user's operation. After completing the clothes dropping and detergent dropping, when the user closes the drop opening, the drop opening can be covered by the door body, realizing the hidden design of the drop opening, improving the appearance integrity of the clothes processing device. In addition, by arranging the drop opening below the first reference plane, that is, arranging the drop opening below the drop opening, the height of the drop opening can be appropriately reduced, facilitating the user to add the detergent.

[0095] Compared with the prior art, the beneficial effects of the present application are:

[0096] The clothes processing device of the present application can expose the drop opening and the drop opening by rotating the door body, the user can put the clothes to be washed through the drop opening, and add the detergent to the inside of the liquid storage box through the drop opening, without separate operation of the liquid storage box, reducing the user's operation.

[0128] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In the description of the embodiments of the present application, unless otherwise specified, “ / ” represents the meaning of or, for example, A / B can represent A or B; “and / or” in this document only represents a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which means that there are three cases of A alone, A and B together, and B alone. In addition, in the description of the embodiments of the present application, “multiple” means two or more than two.

[0129] Hereinafter, the terms "first", "second", "third", etc. are used only for descriptive purpose, and cannot be understood as indicating or implying relative importance or implying the number of the technical features indicated. Thus, the features defined with "first", "second", "third", etc. can explicitly or implicitly include one or more of the features.

[0130] For the purpose of illustration and not limitation, specific details are set forth, such as particular system configurations, techniques, etc., in order to provide a thorough understanding of the embodiments disclosed herein. However, it will be apparent to those skilled in the art that the embodiments disclosed herein can be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the embodiments disclosed herein with unnecessary detail.

[0131] When a user washes laundry using a laundry treating apparatus, such as a washing machine, in order to improve the washing effect, the user usually adds a detergent, such as a laundry liquid, a softener, etc., into a drum of the laundry treating apparatus after the laundry is put in. At present, the washing machine is usually provided with a separate drawer type liquid storage box. When the detergent needs to be added, the user can pull out the liquid storage box, and after the detergent is added into the liquid storage box, the liquid storage box is pushed back to the original position. Generally, in order to improve the utilization rate of the internal space of the washing machine, the liquid storage box is arranged at a relatively high position in the washing machine, so that the detergent automatically flows downward and enters a water inlet pipeline of the washing machine under the action of gravity without being pumped out, so as to be mixed with water flow in the water inlet pipeline and then enter the drum.

[0132] In related designs, the user needs to operate the liquid storage box, such as pulling out and pushing back, every time the user performs a washing operation, which causes the washing operation to be relatively cumbersome and affects the user experience. Moreover, the surface of the laundry treating apparatus needs to be opened so that the liquid storage box can be pulled out by the user and reset through the opening, which will damage the integrity of the appearance of the laundry treating apparatus. In addition, the bottom of the drawer type liquid storage box needs to be provided with an opening, so that after the liquid storage box is reset by the user, the detergent can flow out of the liquid storage box and enter the water inlet pipeline through the opening, so that the detergent can flow out of the through hole during the process of the user adding the detergent and pushing back the liquid storage box, which causes waste.

[0133] To solve the problems in the related art, the inventors attempt to set a liquid pumping pump, and make the liquid pumping pump extend into the liquid storage box from top to bottom through a hose, so as to pump out the detergent in the liquid storage box. In this way, the opening in the bottom of the liquid storage box is not needed, and the waste caused by the leakage of the detergent can be avoided. However, the above setting still cannot solve the problem that the user needs to separately operate the liquid storage box when performing a washing operation, and cannot further simplify the operation process of the user.

[0134] Therefore, the laundry treatment device provided in the present application can expose the dropping opening and the feeding opening by rotating the door body, the user can drop the laundry to be washed through the dropping opening and add the detergent to the inside of the liquid storage box through the feeding opening, without the need for separate operation of the liquid storage box, reducing the user's operation. After completing the laundry dropping and the detergent dropping, when the user closes the door body, the dropping opening and the feeding opening can be covered by the door body, realizing the hidden design of the feeding opening, improving the appearance integrity of the laundry treatment device. In this way, the user's operation process of washing the laundry can be simplified, and the appearance of the laundry treatment device can be more simple and beautiful.

[0135] The laundry treatment device provided in the present application embodiments can have various implementation forms, for example, can be a washing machine, a drying machine, a washing-drying integrated machine, etc. When the laundry treatment device is a washing machine, can be a drum washing machine, a pulsator washing machine, etc., can be a single-drum washing machine or a multi-drum washing machine.

[0136] That is, the laundry treatment device of the present application involves multiple drums, if taking the laundry treatment device as a washing machine as an example, the multiple drums can all be used for washing laundry. Or, the laundry treatment device is a washing-drying integrated machine, among the multiple drums, part of the drums can be used for washing laundry, and the other part of the drums can be used for drying laundry; or, all the drums can be used for washing and drying laundry, and different drums can execute the same program at the same time, or can execute different programs at the same time.

[0137] It can be understood that when the laundry treatment device involves multiple drums, the multiple drums can run simultaneously, or can also run independently. For example, when at least one drum is executing a washing or rinsing program, there can be at least one drum executing a dehydration or drying program, or there can be at least one drum in a standby state without executing any program.

[0138] The technical solutions of the present application will be further described below in combination with embodiments and drawings.

[0140] The laundry treatment device 100 comprises a cabinet 110, a drum 120, a liquid storage box 130 and a door body 140. The cabinet 110 comprises a front side plate 111 and a main frame 112, wherein the front side plate 111 is connected to the main frame 112 and encloses a receiving chamber 113 with the main frame 112.

[0141] The drum 120 is arranged in the receiving chamber 113. The liquid storage box 130 is arranged in the receiving chamber 113 and is used to contain a detergent. The liquid storage box 130 is connected to the drum 120 and can deliver the detergent to the drum 120 to clean the laundry to be treated by using the detergent. The door body 140 is rotatably arranged on the front side plate 111. By rotating the door body 140 to make the door body 140 close to the front side plate 111, the door body 140 can cover the drum 120, or by rotating the door body 140 to make the door body 140 away from the front side plate 111, the drum 120 can be exposed to facilitate the user to put in the laundry to be treated or take out the treated laundry.

[0142] The front side plate 111 is provided with a putting opening 111a and a feeding opening 111b. The putting opening 111a is arranged corresponding to the drum 120 and is in communication with the drum 120. The feeding opening 111b is in communication with the liquid storage box 130. By rotating the door body 140 to make the door body 140 close to the front side plate 111, the door body 140 can cover the putting opening 111a and the feeding opening 111b, or by rotating the door body 140 to make the door body 140 away from the front side plate 111, the putting opening 111a and the feeding opening 111b can be exposed.

[0143] In this way, when the user needs to wash the laundry, by rotating the door body 140 to make the door body 140 away from the front side plate 111, the putting opening 111a and the feeding opening 111b of the laundry treatment device 100 can be exposed, and the user can put in the laundry and add the detergent. In this way, the user can see the feeding opening 111b when opening the door body 140, and does not need to pull out the liquid storage box alone to add the detergent and then open the door body to put in the laundry, which can save the user's operation of washing the laundry. In addition, after the user finishes putting in the laundry and adding the detergent, the door body 140 is rotated to make the door body 140 close to the front side plate 111, and the putting opening 111a and the feeding opening 111b can be covered by the door body 140. That is to say, the feeding opening 111b is a hidden opening and cannot be seen when the door body 140 is closed, which can reduce the number of openings on the surface of the cabinet 110 and make the appearance of the laundry treatment device 100 more neat and beautiful.

[0144] Therefore, by using the laundry treatment device 100 of the present application, when the user closes the door body 140, the door body 140 can cover the putting opening 111a and the feeding opening 111b at the same time, thereby realizing the hidden design of the feeding opening 111b. When the user opens the putting opening 111a, the feeding opening can be opened, and at this time, the user can realize the synchronous putting in and taking out of the laundry or the putting in of the detergent, which is more convenient to use.

[0145] In the present application, the detergent is a treating agent for laundry treatment, which can be a cleaning agent such as laundry liquid, and can also be a care agent for caring for laundry, such as a softener.

[0146] It can be understood that the door body 140 has two opposite ends, one end of the door body 140 can be rotatably connected to the front side plate 111 through a hinge, and the other end can be provided with a first locking structure (not shown in the figure), and the front side plate 111 is provided with a second locking structure 111c matched with the first locking structure. When the door body 140 is rotated relative to the front side plate 111 to the first locking structure and the second locking structure 111c matched and locked, the door body 140 covers the dropping port 111a and the feeding port 111b, and the user can start the laundry treatment device 100 to treat the laundry.

[0147] Optionally, the first locking structure and the second locking structure 111c can be buckle structures or other structures capable of achieving quick locking and matching, for example, the first locking structure can have a socket, and the second locking structure has a hook or a fastener. When the door body 140 covers the dropping port 111a and the feeding port 111b, the first locking structure and the second locking structure 111c are matched and locked, so that the door body 140 is fixed, and the drum 120 remains in a closed state. After the laundry is washed, the locking state between the first locking structure and the second locking structure 111c is released, the user can rotate the door body 140 to expose the dropping port 111a, and then take out the washed laundry through the dropping port 111a.

[0148] Please see Figure 5 and Figure 6 , Figure 5 is a schematic view of a front side plate of an embodiment of the present application, Figure 6 is an assembly view of a front side plate and a door body in an embodiment of the present application.

[0149] In some embodiments, the front side plate 111 is provided with a recessed portion 114 recessed relative to the front side plate 111, and when the door body 140 is rotated to cover the dropping port 111a and the feeding port 111b, the door body 140 is at least partially embedded in the recessed portion 114. In this way, the protruding degree of the door body 140 relative to the front side plate 111 can be reduced, which is helpful to realize the miniaturization design of the laundry treatment device 100, and is also conducive to improving the flatness of the overall appearance of the laundry treatment device 100, so that the appearance of the laundry treatment device 100 is more beautiful.

[0150] It can be understood that the recessed portion 114 is recessed relative to the front side plate 111 towards the accommodation chamber 113, and the recessed portion 114 can surround a groove 114a, and when the door body 140 is at least partially embedded in the recessed portion 114, it is at least partially contained in the groove 114a.

[0151] In some embodiments, the door body 140 is rotatably arranged in the recess 114, and when the door body 140 is rotated to cover the dropping port 111a and the feeding port 111b, the surface of the door body 140 away from the drum 120 is flush with the surface of the front side plate 111 away from the drum 120. In this way, the appearance of the clothes treatment apparatus 100 is more flat and regular, and thus the overall appearance of the clothes treatment apparatus 100 is more beautiful.

[0152] It should be noted that the "flush" mentioned herein is not limited to the case where two planes are strictly aligned, and in the present application, when the distance between the surface of the door body 140 away from the drum 120 and the surface of the front side plate 111 away from the drum 120 is not greater than 10 mm, it can be considered that the surface of the door body 140 away from the drum 120 is flush with the surface of the front side plate 111 away from the drum 120. Specifically, when the door body 140 is rotated to the first locking structure and the second locking structure 111c are locked, the surface of the door body 140 away from the drum 120 can protrude a distance of not greater than 10 mm relative to the surface of the front side plate 111 away from the drum 120, or the surface of the door body 140 away from the drum 120 can be recessed a distance of not greater than 10 mm relative to the surface of the front side plate 111 away from the drum 120 towards the accommodation chamber 113.

[0153] In some embodiments, a handle 141 can be arranged on the door body 140 to facilitate the user to open or close the door body 140.

[0154] Again referring to Figure 5 In some embodiments, the recess 114 includes a bottom wall portion 114b and a side wall portion 114c, and the side wall portion 114c is arranged around and connected to the bottom wall portion 114b. It can be understood that the bottom wall portion 114b and the side wall portion 114c together enclose the above-mentioned groove 114a.

[0155] In some embodiments, the dropping port 111a is arranged on the bottom wall portion 114b, and the feeding port 111b is arranged on the side wall portion 114c, and the opening direction of the dropping port 111a and the opening direction of the feeding port 111b intersect. By arranging the dropping port 111a and the feeding port 111b on the bottom wall portion 114b and the side wall portion 114c of the recess 114 respectively, it is possible to avoid occupying the setting space of the dropping port 111a when arranging the feeding port 111b, so that the dropping port 111a has sufficient setting space, which facilitates the user to put or take out clothes, and it is also possible to avoid increasing the area of the door body to cover the dropping port 111a and the feeding port 111b, which is helpful for the miniaturization design of the clothes treatment apparatus 100. In addition, the opening direction of the feeding port 111b and the opening direction of the dropping port 111a intersect, which can reduce the difficulty of the user adding detergent through the feeding port 111b.

[0156] It can be understood that the bottom wall part 114b and the side wall part 114c can be integrally arranged or separately arranged. In the present embodiment, the bottom wall part 114b and the side wall part 114c are taken as examples for illustration, but the present application is not limited thereto. In addition, the door body 140 can be rotatably connected to the side wall part 114c through a hinge arranged on the side wall part 114c, and the second locking structure 111c is arranged on the bottom wall part 114b.

[0157] In some embodiments, the bottom wall part 114b extends along the height direction H of the cabinet 110, the side wall part 114c extends along a direction intersecting the height direction H, the dropping opening 111a is an opening arranged on the bottom wall part 114b, and the feeding opening 111b is an opening arranged on the side wall part 114c, so that the opening direction of the dropping opening 111a and the opening direction of the feeding opening 111b intersect.

[0158] In some embodiments, the side wall part 114c can extend along a horizontal direction, and in this case, the opening direction of the feeding opening 111b is perpendicular to the opening direction of the dropping opening 111a.

[0159] In some embodiments, the side wall part 114c includes a first flat section 114d, a second flat section 114e, and two connecting sections 114f. The first flat section 114d and the second flat section 114e are arranged at intervals along the height direction H, and the two connecting sections 114f are arranged at intervals along the horizontal direction. The connecting section 114f on the same side of the first flat section 114d and the second flat section 114e is connected to the end on the same side of the first flat section 114d and the second flat section 114e, so that the first flat section 114d, the second flat section 114e, and the two connecting sections 114f jointly constitute the above-mentioned side wall part 114c.

[0160] In some embodiments, the two connecting sections 114f can be arranged as arc-shaped connecting sections, so that the side wall part 114c forms a waist-round shape or an elliptical shape, making the appearance of the clothes treatment device 100 more beautiful, and at the same time, reducing the occupation of the internal space of the cabinet 110 by the recessed part 114.

[0161] In some embodiments, the first flat section 114d is arranged above the dropping opening 111a along the height direction H, the second flat section 114e is arranged below the dropping opening 111a along the height direction H, and the feeding opening 111b is arranged on the second flat section 114e. That is, the feeding opening 111b is arranged below the dropping opening 111a. In this way, the height of the feeding opening 111b can be appropriately reduced, thereby reducing the difficulty for the user to add detergent to the detergent storage box 130 through the dropping opening 111b. In addition, it is also convenient to arrange the pipeline connection of the feeding opening 111b and the detergent storage box 130, so that the feeding opening 111b is directly connected to the detergent storage box 130 through the pipeline, and the internal structure of the clothes treatment device 100 is simplified.

[0162] In some embodiments, the bottom wall portion 114b is provided with a recessed groove 114g corresponding to the dosing opening 111b, the recessed groove 114g is recessed towards the accommodation chamber 113 relative to the bottom wall portion 114b. By providing the recessed groove 114g on the bottom wall portion 114b corresponding to the position of the dosing opening 111b, a larger operation space can be formed above the dosing opening 111b, which facilitates the user to add detergent to the detergent storage box 130 through the dosing opening 111b when the user pours the container to add detergent to the detergent storage box 130.

[0163] Please refer to Figure 7 , Figure 7 is Figure 5 the schematic view of the dosing opening cover assembly shown in FIG. 1.

[0164] In some embodiments, the laundry treating apparatus 100 comprises a cover assembly 150, the cover assembly 150 is connected with the front side plate 111, the cover assembly 150 is at least partially embedded in the dosing opening 111b, and is used to cover the dosing opening 111b. In many scenarios, after the user uses the laundry treating apparatus 100 to complete the washing operation and takes out the laundry, the user usually keeps the door body 140 in an open state to ventilate the drum 120. At this time, the cover assembly 150 is used to cover the dosing opening 111b, which can prevent dust, sewage or other sundries from entering the dosing opening 111b, thereby avoiding the situation that the detergent storage box 130 is contaminated, the pipeline is blocked, and the like.

[0165] The cover assembly 150 is at least partially embedded in the dosing opening 111b, which can reduce the protrusion of the cover assembly 150 relative to the front side plate 111, so that even if the user does not take out the cover assembly 150, it will not affect the normal closing of the door body 140. It can be understood that the cover assembly 150 is arranged on the second flat plate segment 114e.

[0166] In some embodiments, the cover assembly 150 is detachably connected with the front side plate 111, i.e., detachably connected with the second flat plate segment 114e. When the cover assembly 150 covers the dosing opening 111b, the surface of the cover assembly 150 away from the accommodation chamber 113 is flush with the surface of the second flat plate segment 114e away from the accommodation chamber 113. That is, the outer surface of the cover assembly 150 is flush with the outer surface of the second flat plate segment 114e, so that when the user sets the cover assembly 150 at the dosing opening 111b, the cover assembly 150 can avoid interfering with the normal closing of the door body 140.

[0167] In some embodiments, the cover assembly 150 is detachably connected with the second flat plate segment 114e in a plug-in manner, i.e., the cover assembly 150 can be arranged in a form similar to a plug, and the dosing opening 111b is covered by embedding the cover assembly 150 in the dosing opening 111b.

[0168] When the cover 150 is arranged in the form of a plug, a groove can be arranged on the outer surface of the cover 150, and a protrusion can be arranged in the groove, which divides the groove into two small grooves. A user can hold the protrusion to take out the cover 150 from the feeding opening 111b. Alternatively, an extension can be arranged on the outer surface of the cover 150, which partially covers the opening of the groove. A user can insert a finger into the groove and apply force to the extension to hook the cover 150 out of the feeding opening 111b.

[0169] In some other embodiments, the cover 150 can be arranged in the form of a flip cover. For example, one end of the cover 150 is rotatably connected to the second flat plate segment 114e by a hinge. A user can open or close the feeding opening 111b by flipping the cover 150.

[0170] In some other embodiments, the cover 150 can be arranged in the form of a sliding cover. For example, the cover 150 is slidably arranged on the second flat plate segment 114e. A user can open or close the feeding opening 111b by sliding the cover 150 relative to the second flat plate segment 114e.

[0171] It can be understood that when the cover 150 is arranged in the form of a flip cover or a sliding cover, the opening or closing of the cover 150 can also be arranged to be automatic, i.e., realized by a driving component such as a motor or an electric cylinder. For example, a sensor can be arranged on the front side plate 111 or the door body 140 to sense the action of a user opening the door body 140. A control button can be arranged on the control panel of the clothes treatment device 100. When the sensor detects the action of opening the door body 140, the driving component drives the cover 150 to automatically open the feeding opening 111b. Alternatively, a user can drive the driving component to open the feeding opening 111b by the control button on the control panel, so as to add detergent. Subsequently, the user can manually reset the cover 150, or drive the driving component to close the feeding opening 111b by the control button on the control panel.

[0172] Optionally, the material of the cover 150 can include but is not limited to plastic, rubber, or silicone, etc. It can be understood that when the cover 150 is made of a material such as rubber or silicone that has elasticity, the cover 150 can slightly protrude from the outer surface of the first flat plate segment 114e. When the door body 140 is closed, the cover 150 can be pressed by the door body 140, so as to produce conformal deformation, without affecting the normal closing of the door body 140. In addition, when the door body 140 is subjected to an unexpected force, causing the door body 140 to hit the front side plate 111, the part of the cover 150 protruding from the surface of the second flat plate segment 114e can play a buffering role.

[0173] Please refer to Figure 8 andFigure 9 , Figure 8 is Figure 3 a front view schematic diagram of the clothes treatment device, Figure 9 is Figure 7 a front view schematic diagram of the front side.

[0174] In some embodiments, the clothes treatment device 100 can be a double drum washing machine, at this time, the drum 120 includes a first sub-drum 121 and a second sub-drum 122. The first sub-drum 121 is arranged in the receiving chamber 113, and the second sub-drum 122 is arranged in the receiving chamber 113 and spaced apart from the first sub-drum 121.

[0175] Correspondingly, the feeding port 111a includes a first sub-feeding port 111d and a second sub-feeding port 111e, the first sub-feeding port 111d and the first sub-drum 121 are arranged correspondingly and communicate with each other, and the second sub-feeding port 111e and the second sub-drum 122 are arranged correspondingly and communicate with each other. At this time, the feeding opening 111b can be arranged between the first sub-feeding port 111d and the second sub-feeding port 111e. By arranging the drum 120 as two sub-drum, different clothes can be washed separately when washing clothes, for example, underwear and socks can be washed separately to meet the hygiene needs.

[0176] In some embodiments, the first sub-drum 121 and the second sub-drum 122 are arranged spaced apart in the horizontal direction, and correspondingly, the first sub-feeding port 111d and the second sub-feeding port 111e are arranged spaced apart in the horizontal direction, at this time, the feeding opening 111b is arranged between the first sub-feeding port 111d and the second sub-feeding port 111e in the horizontal direction. By arranging the first sub-drum 121 and the second sub-drum 122 spaced apart in the horizontal direction, the height of the clothes treatment device 100 can be reduced, thereby reducing the height of the center of gravity of the clothes treatment device 100, thereby improving the stability of the clothes treatment device 100. And the feeding opening 111b is arranged between the first sub-feeding port 111d and the second sub-feeding port 111e, the first sub-feeding port 111d and the second sub-feeding port 111e are symmetrically arranged about the feeding opening 111b, which makes the appearance of the clothes treatment device 100 more beautiful, and the internal pipeline of the clothes treatment device 100 can be arranged in a symmetrical form with the position of the feeding opening 111b as a reference, which is beneficial to reduce the difficulty of arranging the internal pipeline.

When the door body 140 is arranged as one, the door body 140 is used to open or close the first sub-roller 121 and the second sub-roller 122 at the same time.

[0178] Please see Figure 10 and Figure 11 , Figure 10 is a perspective view of another embodiment of the laundry processing device, Figure 11 is Figure 10 a front view of the laundry processing device shown in FIG. 1.

[0179] When the door body 140 is arranged as two, the recess 114 can be arranged as one or two, Figure 10 and Figure 11 is a schematic view when the recess 114 is arranged as two. Wherein the two door bodies 140 are arranged respectively corresponding to the two recesses 114, when the door body 140 corresponding to the first sub-feeding port 111d covers the first feeding port 111d, the door body 140 is at least partially embedded in the corresponding recess 114. Similarly, when the other door body 140 corresponding to the second sub-feeding port 111e covers the second sub-feeding port 111e, the door body 140 is at least partially embedded in the corresponding recess 114.

[0180] Of course, in other embodiments, the first sub-roller 121 and the second sub-roller 122 can also be arranged in a height direction H, and the first sub-roller 121 is below the second sub-roller 122. At this time, the feeding port 111b can be arranged between the first sub-roller 121 and the second sub-roller 122 in the height direction H, or below the first sub-roller 121.

The dispensing pump 161 can draw the detergent in the liquid storage box 130 into the liquid delivery pipe 162. The other end of the liquid delivery pipe 162 is connected to one end of the mixing pipe 163, and the other end of the mixing pipe 163 is connected to the water inlet pipe 152 of the laundry treating apparatus 100. The detergent enters the mixing pipe 163, mixes with the water flow from the water inlet pipe 152 into the mixing pipe 163, and then enters the drum 120 through the water inlet pipe 152. The detergent mixes with the water flow in the mixing pipe 163 before entering the drum 120, which can improve the dispersion of the detergent and thus improve the washing effect.

[0193] In some embodiments, the dispensing pump 161 can be arranged on the top of the liquid storage box 130 and connected to the liquid storage box 130. The dispensing pump 161 is connected to the liquid storage box 130 by a hose.

[0194] When the water inlet pump 151 and part of the water inlet pipe 152 are arranged on the bottom plate 115, the liquid delivery pipe 162 and the mixing pipe 163 can be arranged on the bottom plate 115, so that the mixing pipe 163 is connected to the part of the water inlet pipe 152 arranged on the bottom plate 115. When the water inlet pump 151 and the water inlet pipe 152 are arranged on the top plate, part of the liquid delivery pipe 162 and the mixing pipe 163 can also be arranged on the top plate, i.e., the liquid delivery pipe 162 extends upward. In this way, the dispensing pump 161 can draw the detergent in the liquid storage box 130 to flow upward and into the mixing pipe 163, and then mix with the detergent passing through the mixing pipe 163.

[0195] In some embodiments, the liquid storage box 130 can comprise a first sub-liquid storage box (not shown) and a second sub-liquid storage box (not shown). The dispensing pump 161 can be connected to both sub-liquid storage boxes, or two dispensing pumps 161 can be arranged, each corresponding to one sub-liquid storage box. The first sub-liquid storage box can be used to store a first type of detergent, such as a cleaning agent like laundry detergent, and the second sub-liquid storage box can be used to store a second type of detergent, such as a care agent like softener. It can be understood that the types of detergents can be distinguished according to different functions, or distinguished according to components, brands, etc.

[0196] During the washing process, the dispensing pump 161 can be arranged to first draw the laundry detergent in the first sub-liquid storage box to clean the clothes in the drum 120. After the clothes are cleaned, the dispensing pump 161 draws the care agent in the second sub-liquid storage box to care for the cleaned clothes.

[0197] It can be understood that when the first sub-tank and the second sub-tank are connected to different dispensing pumps 161, the dispensing pump 161 provided in the first sub-tank can first extract laundry detergent in the first sub-tank, and after the completion of the laundry cleaning, the dispensing pump 161 connected to the second sub-tank extracts the care agent in the second sub-tank.

[0198] When the tank includes the first sub-tank and the second sub-tank, the first sub-tank and the second sub-tank can be mixed with the water flow in the water inlet pipeline 152 through the same liquid conveying pipe 162 and the mixing pipe 163. Alternatively, different liquid conveying pipes 162 and mixing pipes 163 can be provided, and the first sub-tank is connected to the water inlet pipeline through the corresponding connected liquid conveying pipe 162 and mixing pipe 163. The second sub-tank is connected to the water inlet pipeline 152 through the corresponding connected, another liquid conveying pipe 162 and mixing pipe 163.

[0199] It can be understood that when the recess 114 is provided with two, each recess 114 can be provided with two feeding ports 111b, one of which is connected to the first sub-tank, and the other is connected to the second sub-tank.

[0200] It can be understood that when the drum 120 includes the first sub-drum 121 and the second sub-drum 122, the water inlet pipeline 152 can be provided as a Y-shaped pipeline. Specifically, after the water inlet pipeline 152 is mixed with the detergent at the mixing pipe 163, the water inlet pipeline 152 can be divided into two paths, and the two paths of the water inlet pipeline 152 are respectively connected to the first sub-drum 121 and the second sub-drum 122, so as to inject the water mixed with the detergent into the first sub-drum 121 and the second sub-drum 122.

[0201] In some other embodiments, the water inlet pipeline 152 can also be provided as two independent paths, and the two paths of the water inlet pipeline 152 are respectively connected to the first sub-drum 121 and the second sub-drum 122. Correspondingly, the mixing pipe 163 includes the first sub-mixing pipe 163a and the second sub-mixing pipe 163b, and the first sub-mixing pipe 163a and the second sub-mixing pipe 163b are both connected to the liquid conveying pipe 162, that is, the liquid conveying pipe 162 can be provided as a Y-shaped pipeline with two liquid conveying ports, one of which is connected to the first sub-mixing pipe 163a, and the other is connected to the second sub-mixing pipe 163b. One path of the water inlet pipeline 152 is connected to the first sub-mixing pipe 163a, and the water flow enters the first sub-mixing pipe 163a to mix with the detergent. The other path of the water inlet pipeline 152 is connected to the second sub-mixing pipe 163b, and the water flow enters the second sub-mixing pipe 163b to mix with the detergent. Then, the two paths of the water inlet pipeline 152 respectively inject the water mixed with the detergent into the corresponding drum.

[0202] It can be understood that when the water inlet pipeline 152 is provided as two independent water inlet pipelines, the water inlet pump 151 can also be provided as two, and the two water inlet pumps 151 are respectively connected to the two water inlet pipelines 152.

[0203] In some embodiments, the infusion tube 162 is provided with a flow limiting portion 162a, and the flow limiting portion 162a is located in the mixed liquid tube 163 and is radially contracted in the infusion direction of the infusion tube 162 to form a first flow limiting opening 162b. By providing the flow limiting portion 162a in the mixed liquid tube 163, the flow limiting portion 162a is radially contracted in the infusion direction to form the first flow limiting opening 162b, so that the water in the mixed liquid tube 163 can be prevented from flowing back to the injection pump 161 or even the liquid storage box 130 from the infusion tube 162.

[0204] In some embodiments, the flow limiting portion 162a is arranged around the inner wall of the mixed liquid tube 163 to form the first flow limiting opening 162b. The flow limiting portion 162a is gradually contracted in the infusion direction to form a funnel-shaped through hole, and the outer wall of the flow limiting portion 162a and the inner wall of the mixed liquid tube 163 form an annular space, and the radial dimension of the annular space gradually increases in the infusion direction. When the water flow of the water inlet pipeline 152 enters the infusion tube 162 from the mixed liquid tube 163, the size of the first flow limiting opening 162b is reduced due to the radial contraction of the flow limiting portion 162a, so that the water flow is difficult to continue to enter the inside of the infusion tube 162 through the flow limiting opening 162b.

[0205] In some embodiments, the end portion of the mixed liquid tube 163 connected with the infusion tube 162 is radially contracted to form a second flow limiting opening 162c. The end portion of the mixed liquid tube 163 connected with the infusion tube 162 is radially contracted to reduce the hole diameter at the position where the mixed liquid tube 163 is connected with the infusion tube 162, thereby forming the second flow limiting opening 162c, so that the water flow is difficult to continue to enter the inside of the infusion tube 162 through the flow limiting opening 162b.

[0206] In some embodiments, the first flow limiting opening 162b and the second flow limiting opening 162c are arranged in the infusion direction of the infusion tube 162 in a spaced manner, and the cooperation of the first flow limiting opening 162b and the second flow limiting opening 162c can improve the flow limiting effect and prevent the water in the water inlet pipeline 152 from entering the infusion tube 162 through the connection between the infusion tube 162 and the mixed liquid tube 163.

[0207] It can be understood that when the roller 120 includes the first sub-roller 121 and the second sub-roller 122, the first flow limiting opening 162b and the second flow limiting opening 162c are both two, that is, the infusion tube 162 can deliver the detergent to one water inlet pipeline 152 through one first flow limiting opening 162b and one second flow limiting opening 162c, and deliver the detergent to another water inlet pipeline 152 through another first flow limiting opening 162b and another second flow limiting opening 162c.

[0208] In some embodiments, the mixing pipe 163 comprises a first body section 163c, a reduced diameter section 163d, and a second body section 163e, the reduced diameter section 163d is connected to the other end of the liquid delivery pipe 162, one end of the first body section 163c is connected to the drum 120, the other end of the first body section 163c is connected to the reduced diameter section 163d, one end of the second body section 163e is connected to the reduced diameter section 163d, and the other end of the second body section 163e is used to connect to the water inlet pipe 152, the inner diameter of the reduced diameter section 163d is smaller than the inner diameter of the first body section 163c and the second body section 163e.

[0209] The inner diameter of the middle section of the mixing pipe 163 is set to be smaller than the inner diameter of the two ends, when the water flow from the water inlet pipe 152 enters the mixing pipe 163, due to the Venturi effect, the flow rate of the water flow at the reduced diameter section 163d is greater than the flow rate of the water flow at the first body section 163c and the second body section 163e, which can improve the mixing efficiency of the detergent and the water flow. In addition, since the flow rate of the water flow at the reduced diameter section 163d is greater, the pressure is smaller, and a pressure difference is formed with the inside of the liquid delivery pipe 162, which helps to suck out the detergent in the liquid delivery pipe 162, avoiding the detergent remaining in the liquid delivery pipe 162 to cause blockage.

[0210] Exemplarily, the mixing pipe 163 can be a three-way pipe, the first body section 163c has a first connecting port 163f for connecting and communicating with the drum 120, the reduced diameter section 163d has a second connecting port 163g for connecting and communicating with the liquid delivery pipe 162, and the second body section 163e has a third connecting port 163h for connecting and communicating with the water inlet pipe 152.

[0211] In some embodiments, the inner diameter of the first body section 163c and the second body section 163e is D1, the inner diameter of the reduced diameter section 163d is D2, and D1, D2 satisfy the relationship: 0.3D1 < D2 < 0.7D1. In this way, the inner diameter of the reduced diameter section 163d can be effectively reduced to significantly increase the flow rate of the water flow in the reduced diameter section 163d, and the reduced diameter section 163d can also have sufficient unit flow to avoid the phenomenon of low water inlet efficiency due to the small cross-sectional area of the reduced diameter section 163d. When 0.3D1 > D2, the inner diameter of the reduced diameter section 163d is too small, which directly leads to a significant reduction in the flow area of the reduced diameter section 163d, resulting in a low water inlet efficiency of the water inlet pipeline 152. In addition, according to the Poiseuille law, due to the reduction of the inner diameter of the reduced diameter section 163d, the flow rate of the water flow in the reduced diameter section 163d will significantly increase, thereby increasing the resistance of the water flow in the reduced diameter section 163d. The water inlet pump 151 needs to drive the water flow to flow against the resistance of the reduced diameter section, which also increases the load of the water inlet pump 151 to some extent. When D2 is greater than 0.7D1, the inner diameter of the reduced diameter section 163d is reduced by a smaller margin compared to the inner diameters of the first body section 163c and the second body section 163e. In this way, the flow rate of the water flow in the reduced diameter section 163d is not significantly increased compared to the flow rate of the water flow in the first body section 163c and the second body section 163e, and the pressure difference between the inside of the reduced diameter section 163d and the inside of the delivery pipe 162 is relatively small. The extraction efficiency of the detergent in the delivery pipe 162 is also reduced, and the mixing efficiency of the detergent and the water flow cannot be effectively improved.

[0212] In some other embodiments, the inner diameters of the first body section 163c and the second body section 163e can be different. For example, the inner diameter of the second body section 163e is D3, and D2 < D1, and / or D2 < D3, and / or D1 < D3.

[0213] In one example, D1, D2, and D3 satisfy the relationship: D2 < D1 < D3.

[0214] In some other embodiments, D1, D2, and D3 can also satisfy the following relationship: D2 < D1, and / or D2 < D3, and / or D3 < D1.

[0215] In one example, D1, D2, and D3 satisfy the relationship: D2 < D3 < D1.

[0216] In some embodiments, the mixing pipe 163 further comprises a first variable diameter section 163i, one end of the first variable diameter section 163i being connected to the first main body section 163c, and the other end of the first variable diameter section 163i being connected to the reduced diameter section 163d. That is, the first main body section 163c is connected to the reduced diameter section 163d through the first variable diameter section 163i, and the inner diameter of the first variable diameter section 163i gradually increases along the water flow direction of the mixing pipe 163. In this way, the change in the inner diameter between the first main body section 163c and the reduced diameter section 163d is more gradual, which reduces the resistance to water flow inside the mixing pipe 163, and helps to increase the flow rate of the water flow.

[0217] In some embodiments, the mixing pipe 163 further comprises a second variable diameter section 163j, one end of the second variable diameter section 163j being connected to the reduced diameter section 163d, and the other end of the second variable diameter section 163j being connected to the second main body section 163e. That is, the second main body section 163e is connected to the reduced diameter section 163d through the second variable diameter section 163j, and the inner diameter of the second variable diameter section 163j gradually decreases along the water flow direction of the mixing pipe 163. In this way, the change in the inner diameter between the second main body section 163e and the reduced diameter section 163d is more gradual, which reduces the resistance to water flow inside the mixing pipe 163, and helps to increase the flow rate of the water flow.

[0218] Please refer to Figure 21 , Figure 21 is a structural schematic diagram of another mixing pipe in the embodiments of the present application.

[0219] In some other embodiments, the mixing pipe 163 does not have the reduced diameter section 163d and the variable diameter section, that is, the inner diameter of the mixing pipe 163 remains substantially unchanged. At this time, as long as there is water flow inside the mixing pipe 163, the pressure inside the mixing pipe 163 will be less than the pressure inside the detergent supply pipe 162, and then the detergent inside the detergent supply pipe 162 will be sucked into the mixing pipe 163 through the pressure difference.

[0220] It can be found that when there is water flow in the mixing pipe 163, the detergent inside the detergent supply pipe 162 can be sucked through the pressure difference. Therefore, when the drum 120 comprises the first sub-drum 121 and the second sub-drum 122, if only one of the first sub-drum 121 and the second sub-drum 122 performs washing, that is, only one of them is supplied with water, then only the corresponding water supply pipeline 152 is expected to be filled with water, and only the corresponding sub-mixing pipe is expected to have water flow, so that as long as the sub-mixing pipe can extract the detergent in the detergent supply pipe 162, the other sub-mixing pipe without water flow cannot extract the detergent in the detergent supply pipe 162. If both the first sub-drum 121 and the second sub-drum 122 perform washing, the amount of detergent extracted by the two can be controlled by controlling the water supply time / water supply amount of the two.

[0221] In some embodiments, a laundry treating apparatus 100 is also provided, which includes a cabinet 110, a drum 120, a liquid storage box 130, and a door 140. The cabinet 110 includes a front side plate 111 and a main frame 112, wherein the front side plate 111 is connected to the main frame 112 and encloses a receiving chamber 113 with the main frame 112.

[0222] The drum 120 is disposed in the receiving chamber 113. The liquid storage box 130 is disposed in the receiving chamber 113 and is configured to store a detergent. The liquid storage box 130 is connected to the drum 120 and configured to deliver the detergent to the drum 120 for washing the laundry to be treated by the detergent. The door 140 is rotatably disposed on the front side plate 111. By rotating the door 140 to move the door 140 away from the front side plate 111, the drum 120 is exposed to facilitate a user to put the laundry to be treated or take out the treated laundry. Alternatively, by rotating the door 140 to move the door 140 close to the front side plate 111, the door 140 covers the drum 120.

[0223] The front side plate 111 is provided with a putting opening 111a and a feeding opening 111b. The putting opening 111a is disposed corresponding to and in communication with the drum 120. The feeding opening 111b is in communication with the liquid storage box 130 and is disposed below the putting opening 111a in the height direction H. By rotating the door 140 to move the door 140 close to the front side plate 111, the door 140 covers the putting opening 111a and the feeding opening 111b. Alternatively, by rotating the door 140 to move the door 140 away from the front side plate 111, the putting opening 111a and the feeding opening 111b are exposed.

[0224] For example, the putting opening 111a is a circular opening. A horizontal plane passing through the center of the putting opening 111a is a first reference plane. The feeding opening 111b is disposed below the first reference plane in the height direction H. When the door 140 opens the putting opening 111a, the feeding opening 111b is opened. When the door 140 closes the putting opening 111a, the feeding opening 111b is covered.

[0225] The clothes processing device 100 provided in the application can expose the dropping opening 111a and the feeding opening 111b by rotating the door body 140, the user can drop the clothes to be washed through the dropping opening 111a, and add the detergent into the inside of the liquid storage box 130 through the feeding opening 111b, without the need to separately operate the liquid storage box 130, reducing the operation of the user. After the clothes dropping and the detergent dropping are completed, when the user closes the door body 140, the dropping opening 111a and the feeding opening 111b can be covered by the door body 140, realizing the hidden design of the feeding opening 111b, and improving the appearance integrity of the clothes processing device 100. In this way, the operation process of the user in washing the clothes can be simplified, and the appearance of the clothes processing device 100 can be more simple and beautiful.

[0226] For other structures of the clothes processing device, for example, the form and arrangement of the liquid storage box 130, the dropping assembly 160 and other structures, please refer to the description in the foregoing embodiments, which will not be repeated here.

[0227] The above is only a specific embodiment of the application, but the protection scope of the application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the application, which should be covered in the protection scope of the application. Therefore, the protection scope of the application should be subject to the protection scope of the claims.
