Description

Technical Field

[0001] The present invention relates to the technical field of clothing processing, and in particular provides a drawer assembly and a clothing processing device having the drawer assembly. Background Art

[0002] Washing machines are becoming more and more popular due to their convenience, and their applications are becoming more and more common. With the advancement of science and technology and the improvement of people's needs, washing machines are equipped with more and more functional modules, such as automatic delivery modules, weighing modules, etc. The automatic delivery module can realize the automatic delivery of detergents, and the weighing module can obtain the weight of the clothes put into the washing machine, and then the washing program and the amount of detergent to be delivered can be automatically determined according to the weight of the clothes. Taking the automatic delivery module as an example, the automatic delivery module usually includes a detergent storage chamber and a delivery pump. The detergent storage chamber can store detergents, softeners and other clothing treatment agents. After determining the weight of the detergent or softener to be delivered, the corresponding type and weight of clothing treatment agents are delivered into the washing drum through the delivery pump. At present, it is usually through setting multiple accommodating chambers in the detergent box, and detergents, softeners and other clothing treatment agents are stored in different accommodating chambers respectively. In order to facilitate the addition or replacement of clothing treatment agents at any time, the detergent box is usually set in the washing machine in a pull-out manner. When the clothing treatment agent needs to be added or replaced, the detergent box can be pulled out.

[0003] During the operation of the washing machine, the detergent box is usually pushed into the washing machine and connected to the delivery pump. During the operation of the washing machine, especially during the dehydration stage, the washing drum runs at a high speed, which will cause the entire washing machine to vibrate. When the vibration is transmitted to the detergent box, it may cause the detergent box to move outward. Once the detergent box moves outward, it cannot be connected to the delivery pump, resulting in the inability to automatically deliver the clothing treatment agent.

[0004] Accordingly, the art needs a new technical solution to solve the above problems. Summary of the invention

[0005] The present invention aims to solve the above technical problem, that is, to solve the problem in the prior art that the detergent box moves outward due to the vibration of the washing machine, resulting in the inability to normally add detergent or softener.

[0006] In a first aspect, the present invention provides a drawer assembly, comprising a drawer body, a detergent box, and an adsorption device, wherein the detergent box is arranged on the drawer body in a pull-out manner, and the adsorption device is configured to generate an adsorption force between the drawer body and the detergent box so that the detergent box is continuously arranged in the drawer body, and to release the adsorption effect between the detergent box and the drawer body so that the detergent box can be opened relative to the drawer body.

[0007] In the preferred technical solution of the above-mentioned drawer assembly, the adsorption device includes an adsorption chamber, a connecting part and a pressure regulating part, the connecting part is connected to the adsorption chamber, the drawer assembly also includes a connecting hole, the connecting hole has a closed end and an open end, the connecting part is inserted into the connecting hole from the open end, the adsorption chamber is communicated with the connecting hole through the connecting part, the connecting part can move along the axial direction of the connecting hole as the detergent box is pulled relative to the drawer body, the pressure regulating part is configured to form a slight negative pressure in the adsorption chamber when the detergent box is closed relative to the drawer body, thereby generating an adsorption force between the detergent box and the drawer body, and to communicate the adsorption chamber with the external environment when the detergent box is opened relative to the drawer body, thereby releasing the adsorption effect between the detergent box and the drawer body.

[0008] In the preferred technical solution of the above-mentioned drawer assembly, the pressure regulating part includes a first adjusting member and a second adjusting member arranged in the adsorption chamber, the first adjusting member and the second adjusting member can open or close the adsorption chamber, and by opening at least one of the first adjusting member and the second adjusting member, a slight negative pressure can be formed in the adsorption chamber, or the adsorption chamber can be connected to the external environment.

[0009] In the preferred technical solution of the above-mentioned drawer assembly, the first adjusting member includes a first valve stem and a first valve bonnet arranged on the first valve stem, the second adjusting member includes a second valve stem and a second valve bonnet arranged on the second valve stem, and one of the first valve bonnet and the second valve bonnet is located inside the adsorption chamber, and the other is located outside the adsorption chamber.

[0010] In a preferred technical solution of the above drawer assembly, the first adjusting member and / or the second adjusting member are made of an elastomeric material.

[0011] In a preferred technical solution of the above drawer assembly, the side of the adsorption chamber away from the connecting portion is connected to the drawer body, and the connecting hole is provided in the detergent box.

[0012] In a preferred technical solution of the above drawer assembly, the connecting hole is formed by an inward depression of the end portion of the detergent box.

[0013] In a preferred technical solution of the above drawer assembly, the drawer assembly further comprises a sealing member, and the sealing member is clamped between the inner wall of the connecting hole and the connecting portion.

[0014] In a preferred technical solution of the above drawer assembly, a groove is provided at the end of the connecting portion close to the connecting hole, the groove is arranged along the circumference of the connecting portion, and the sealing member is clamped in the groove.

[0015] In the technical solution of the present invention, the drawer assembly includes a drawer body and a detergent box, and the detergent box is arranged on the drawer body in a pull-out manner, that is, when the laundry treatment device is operating normally, the detergent box is pushed inward to close the detergent box relative to the drawer body to ensure the normal delivery of the laundry treatment agent of the laundry treatment device. When the laundry treatment agent needs to be replaced or added, the detergent box is pulled outward to replace or add the laundry treatment agent. The drawer assembly of the present invention also includes an adsorption device, which is configured to generate an adsorption force between the drawer body and the detergent box so that the detergent box can be continuously arranged in the drawer body, and can release the adsorption effect between the detergent box and the drawer body so that the detergent box can be opened relative to the drawer body. Through such a setting, when the detergent box is closed relative to the drawer body, the adsorption force can be generated between the drawer body and the detergent box through the adsorption device. Under this adsorption force, the drawer body can firmly adsorb the detergent box so that it is continuously located in the drawer body. Even if the laundry treatment device vibrates, the detergent box will not move to the outside of the drawer body. When it is necessary to replace or add clothes treatment agent, the adsorption effect between the drawer body and the detergent box can be released through the adsorption device, and the user can pull the detergent box out with a slight force. Through such a setting, the detergent box can be kept in the drawer body when the clothes treatment device is running, avoiding the situation where the detergent box moves outward due to the vibration of the clothes treatment device and thus affecting the automatic delivery of clothes treatment agent. When it is necessary to replace or add clothes treatment agent, the detergent box can be easily pulled out to achieve the replacement or addition of clothes treatment agent, thereby effectively improving the user experience.

[0016] Furthermore, the adsorption device includes an adsorption chamber, a pressure regulating part and a connecting part, the connecting part is connected to the adsorption chamber, and the drawer assembly also includes a connecting hole, the connecting hole has a closed end and an open end, and the connecting part is inserted into the connecting hole from the open end of the connecting hole, thereby realizing the connection between the adsorption device and the connecting hole. When the detergent box is installed, the adsorption chamber is connected to the connecting hole through the connecting part. The connecting part can move relative to the connecting hole along the axial direction of the connecting hole as the detergent box is pulled relative to the drawer body, that is, when the detergent box is opened or closed relative to the drawer body, the connecting part moves back and forth relative to the connecting hole along the axial direction of the connecting hole, thereby ensuring the connection between the adsorption device and the connecting hole, and ensuring that the adsorption chamber, the connecting part and the connecting hole are always in a state of being connected to each other. The pressure regulating part is configured to form a slight negative pressure in the adsorption chamber when the detergent box is closed relative to the drawer body, thereby generating an adsorption force between the detergent box and the drawer body, and to communicate the adsorption chamber with the external environment when the detergent box is opened relative to the drawer body, thereby releasing the adsorption effect between the detergent box and the drawer body. That is, when the detergent box is closed relative to the drawer body, a slight negative pressure is formed in the adsorption chamber by the pressure regulating part, so that a slight negative pressure is formed inside the connecting part and the connecting hole, which is lower than the external atmospheric pressure. Under the action of the atmospheric pressure, an adsorption force is generated between the detergent box and the drawer body, and the detergent box can be firmly arranged on the drawer body through the adsorption force, and will not fall out of the drawer body due to the vibration of the clothing treatment device. When the detergent box is opened relative to the drawer body, the adsorption chamber can be communicated with the external environment by the pressure regulating part, and the pressure in the adsorption chamber is consistent with the atmospheric pressure, and the adsorption force disappears, so that the adsorption effect between the detergent box and the drawer body is released, and the user can pull the detergent box out of the drawer body with a slight force to replace or add clothing treatment agents. That is to say, the present invention forms a slight negative pressure in the adsorption chamber through the pressure regulating part so that the detergent box is continuously in the drawer body, or the adsorption chamber is connected to the external environment so that the user can pull out the detergent box with a slight outward force. This can not only prevent the detergent box from falling out of the drawer body during the operation of the clothing treatment device, but also make it easy to pull the detergent box out of the drawer body when the clothing treatment agent needs to be replaced or added, thereby effectively improving the user experience.

[0017] Furthermore, the drawer assembly also includes a seal, which is arranged between the inner wall of the connecting hole and the connecting part. In this way, the adsorption chamber, the connecting part, and the connecting hole are completely isolated from the external environment. When the detergent box is closed relative to the drawer body, it is easier to form a slight negative pressure in the adsorption chamber, thereby better allowing the detergent box to be continuously located in the drawer body, thereby preventing the detergent box from escaping from the drawer body due to vibration of the clothing processing equipment.

[0018] In a second aspect, the present invention provides a clothes processing device, which includes the drawer assembly described in any of the above solutions.

[0019] It should be noted that the clothes processing device has all the technical effects of the drawer assembly of the aforementioned solution, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Although this embodiment is described by taking a drum washing machine as an example, it can also be applied to other types of clothing processing equipment such as a pulsator washing machine, a washer-dryer, a commercial washing machine, and a shoe washing machine.

[0027] It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "inner", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" to "fifth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0028] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0029] At present, the detergent box is usually set in the washing machine in a pull-out manner. During the normal operation of the washing machine, the detergent box is usually pushed into the washing machine. However, vibrations usually occur during the operation of the washing machine. Under this vibration, the detergent box is easy to move to the outside of the washing machine, resulting in the inability to normally implement the automatic delivery of the laundry treatment agent. To this end, the drawer assembly of the present invention includes an adsorption device, through which an adsorption force can be formed between the drawer body and the detergent box so that the detergent box is continuously arranged in the drawer body. In this way, even if vibrations occur during the operation of the laundry treatment device, the detergent box will not fall out of the drawer body, thereby ensuring the normal operation of the automatic delivery of the laundry treatment agent and improving the user experience.

[0030] Refer to the following Figures 1 to 3 To illustrate possible implementations of the drawer assembly of the laundry processing apparatus of the present invention.

[0031] like Figures 1 to 3As shown, the drum washing machine includes a housing, an outer drum arranged in the housing, and an inner drum arranged in the outer drum, the outer drum can hold washing water, the inner drum can rotate relative to the outer drum, and is connected to the outer drum. The laundry to be washed is put into the inner drum, the drum washing machine is started, and clothing treatment agents (such as detergents, softeners, etc.) and washing water are put into the inner drum to wash the laundry. The drum washing machine of the present invention also includes a drawer assembly, which includes a drawer body 1 and a detergent box 2. The drawer body 1 is usually arranged on the housing, roughly near the top of the housing, and the detergent box 2 is arranged in the drawer body 1 in a pullable manner. The detergent box 2 is used to store detergents, softeners, etc. The detergent box 2 is connected to the delivery pump. When the type of clothing treatment agent to be delivered and the weight of the clothing treatment agent to be delivered are determined, the clothing treatment agent can be delivered into the inner drum through the delivery pump. The drawer assembly of the present invention further includes an adsorption device 3, which is configured to generate an adsorption force between the drawer body 1 and the detergent box 2 so that the detergent box 2 is continuously disposed in the drawer body 1, and to release the adsorption between the detergent box 2 and the drawer body 1 so that the detergent box 2 can be opened relative to the drawer body 1. In this way, when the detergent box 2 needs to be closed, the adsorption force can be generated between the drawer body 1 and the detergent box 2 by the adsorption device 3. Under the adsorption force, the drawer body 1 can firmly adsorb the detergent box 2 so that it is continuously located in the drawer body 1. In this way, even if the drum washing machine vibrates due to the high-speed rotation of the inner drum, the detergent box 2 will not be displaced to the outside of the drawer body 1. When it is necessary to replace or add the laundry treatment agent, the adsorption between the drawer body 1 and the detergent box 2 is released by the adsorption device 3, and the user can pull the detergent box 2 outward with a slight force. That is to say, by providing the adsorption device 3, the present invention can not only keep the detergent box 2 in the drawer body 1 when the drum washing machine is running, thereby preventing the detergent box 2 from moving outward due to the vibration of the drum washing machine and thus affecting the automatic delivery of the clothing treatment agent, but also can easily pull out the detergent box 2 to achieve the replacement or addition of the clothing treatment agent when the clothing treatment agent needs to be replaced or added, thereby effectively improving the user experience.

[0032] It should be noted that the drum washing machine may not be provided with a dispensing pump, that is, the drum washing machine may not be equipped with an automatic dispensing module. In this case, after the user puts the laundry into the inner drum, he can determine the amount of laundry treatment agents such as detergent and softener based on his own experience and the amount of laundry, and put them into the detergent box 2. When the drum washing machine is running, the laundry treatment agents put into the detergent box 2 are carried into the inner drum by the washing water entering the detergent box 2. Without departing from the basic principles of the present application, those skilled in the art can flexibly select the specific type of drum washing machine according to the specific application scenario, and the drum washing machine is within the protection scope of the present application regardless of whether it is equipped with an automatic dispensing module.

[0033] like Figures 1 to 3 As shown and in accordance with Figure 3 In the direction shown, the adsorption device 3 includes an adsorption chamber 31, a connecting portion 32 and a pressure regulating portion 33. The adsorption chamber 31 has a hollow chamber along which Figure 3 The cross section of the middle FF plane is roughly rectangular, and its left side wall is connected to the end of the drawer body 1 facing the detergent box 2 (roughly Figure 3 The connecting portion 32 is a cylindrical structure extending in the horizontal direction and having a substantially circular cross section, the left end of which is connected to the right side wall of the adsorption chamber 31 and the right end of which faces the detergent box 2. The end of the detergent box 2 facing the drawer body 1 (roughly Figure 3 inward (approximately Figure 3 The connecting hole 21 is formed in a depression with one end open (as shown in the figure from left to right), specifically, its left end is an open end 211, and the right end is a closed end 212. The cross-section of the connecting hole 21 is roughly circular and extends in the horizontal direction. When the detergent box 2 is installed, the connecting part 32 is inserted into the connecting hole 21 from left to right. When installed, the outer wall of the connecting part 32 abuts against the inner wall of the connecting hole 21, thereby realizing the mutual communication between the adsorption chamber 31, the connecting part 32 and the connecting hole 21, forming a space isolated from the external environment. When the detergent box 2 is pushed inward or pulled outward, the connecting part 32 is moved along the axial direction of the connecting hole 21 (roughly Figure 3 The horizontal direction shown in the figure moves back and forth relative to the connecting hole 21, so that the adsorption device 3 and the connecting hole 21 are connected to each other, and the adsorption chamber 31, the connecting part 32 and the connecting hole 21 are always in a state of being connected to each other, and a relatively closed space can always be formed between the adsorption chamber 31, the connecting part 32 and the connecting hole 21.

[0034] The pressure regulating part 33 includes a first regulating member 331 and a second regulating member 332, wherein the first regulating member 331 is substantially an umbrella-shaped structure, and includes a first valve stem 3311 and a first valve cap 3312, and the first valve cap 3312 is disposed at the end of the first valve stem 3311 (roughly Figure 3 The second regulating member 332 is generally an umbrella-shaped structure, which includes a second valve stem 3321 and a second valve cap 3322. The second valve cap 3322 is disposed at the end of the second valve stem 3321 (generally Figure 3 The upper end of the second valve stem 3321 shown in FIG. 3 is a diagram of a valve cap 3322 disposed on the upper side wall of the adsorption chamber 31. A first through hole (not shown) is disposed on the upper side wall of the adsorption chamber 31, and a second through hole (not shown) is disposed on the lower side wall of the adsorption chamber 31. When installed, the first valve cap 3312 is located outside the upper side wall of the adsorption chamber 31, and the first valve stem 3311 extends into the interior of the adsorption chamber 31 after passing through the first through hole. The second valve cap 3322 is located inside the adsorption chamber 31, and the second valve stem 3321 extends out of the adsorption chamber 31 after passing through the second through hole.

[0035] Based on the above arrangement, when the detergent box 2 is closed relative to the drawer body 1, the user pushes the detergent box 2 from right to left, the detergent box 2 moves to the left, and the connecting portion 32 penetrates into the connecting hole 21 to the right, squeezing the air in the connecting hole 21. After the air is compressed, the first valve cap 3312 is pushed upward and discharged from the adsorption chamber 31 through the gap between the first valve stem 3311 and the first through hole. When the left end of the connecting portion 32 is roughly flush with the left end of the connecting hole 21, the air in the connecting hole 21 has been basically squeezed out, and the first valve cap 3312 falls downward and abuts against the wall surface of the upper side wall of the adsorption chamber 31. At this time, The pressure in the adsorption chamber 31 will be slightly lower than the atmospheric pressure, forming a slight negative pressure, so that the first valve cap 3312 is tightly adsorbed on the upper side wall of the adsorption chamber 31, similar to the principle of a press-type suction cup adsorbed on a wall. At this time, the lower wall of the second valve cap 3322 is attached to the inner wall of the adsorption chamber 31, so that a slight negative pressure can be maintained in the adsorption chamber 31. Under the action of atmospheric pressure, an adsorption force is generated between the detergent box 2 and the drawer body 1, and the detergent box 2 is firmly fixed in the drawer body 1. Even if the drum washing machine vibrates during operation, the detergent box 2 will not move outside the drawer body 1 or fall out of the drawer body 1. When it is necessary to replace or add clothing treatment agent, the user pulls the detergent box 2 outward from left to right, the detergent box 2 moves to the right, and the space connecting the connecting hole 21 with the adsorption chamber 31 and the connecting part 32 becomes larger, while the amount of air in the adsorption chamber 31 remains unchanged. In this case, the pressure in the adsorption chamber 31 will be further reduced, and the difference in pressure with the external environment will become larger, so that the second valve cap 3322 moves upward, and the external air enters the adsorption chamber 31 from the gap between the second valve stem 3321 and the second through hole, so that the pressure in the adsorption chamber 31 is consistent with the pressure of the external environment, and the adsorption effect between the detergent box 2 and the drawer body 1 is released. The user can pull the detergent box 2 out of the drawer body 1 with a slight force.

[0036] Obviously, it is also possible that the first valve cap 3312 is located inside the adsorption chamber 31, the first valve stem 3311 passes through the lower side wall of the adsorption chamber 31 and extends to the outside of the adsorption chamber 31, and the second valve cap 3322 is located outside the upper side wall of the adsorption chamber 31, and the second valve stem 3321 passes through the upper side wall of the adsorption chamber 31 and extends into the interior of the adsorption chamber 31.

[0037] Although the above description is based on the example that the cross-section of the connecting portion 32 and the connecting hole 21 is circular, it is obviously only an exemplary description and is not restrictive. Without deviating from the basic principles of the present application, technicians in this field can set the cross-section of the connecting portion 32 and the connecting hole 21 to other possible shapes such as ellipse, polygon, rectangle, etc. according to the specific application scenario, as long as the connecting portion 32 can be inserted into the connecting hole 21.

[0038] Although the above description is based on the example that the first regulating member 331 includes the first valve stem 3311 and the first valve cap 3312, and the second regulating member 332 includes the second valve stem 3321 and the second valve cap 3322, it is obviously only an exemplary description and not restrictive. The first regulating member 331 and the second regulating member 332 can obviously also be arranged in other ways. For example, the first regulating member 331 and the second regulating member 332 are solenoid valves. Specifically, the adsorption chamber 31 is provided with a first branch pipe and a second branch pipe, one end of the first branch pipe and the second branch pipe are connected to the adsorption chamber 31, and the other end is connected to the external environment. The first regulating member 331 and The second regulating member 332 is respectively arranged on the first branch pipe and the second branch pipe. When the detergent box 2 is closed, one or both of the first regulating member 331 and the second regulating member 332 are first opened to discharge the air in the adsorption chamber 31 through the first branch pipe or the second branch pipe, thereby making the adsorption chamber 31 slightly negatively pressurized, and then the opened regulating member is closed. When the detergent box 2 is pulled out, one or both of the first regulating member 331 and the second regulating member 332 are opened to allow the air of the external environment to enter the adsorption chamber 31 through the first branch pipe or the second branch pipe, thereby making the pressure in the adsorption chamber 31 the same as that of the external environment, and then the opened regulating member is closed. Without departing from the basic principles of the present application, those skilled in the art can flexibly select the specific setting form of the first regulating member 331 and the second regulating member 332 according to the specific application scenario, as long as a slight negative pressure can be formed in the adsorption chamber 31 or the adsorption chamber 31 is connected to the external environment by opening one of the first regulating member 331 and the second regulating member 332.

[0039] Although the above description is based on the example that the pressure regulating part 33 includes the first regulating member 331 and the second regulating member 332, it is obvious that other settings can also be adopted. For example, the pressure regulating part 33 includes a micro vacuum pump, which is connected to the adsorption chamber 31. When the detergent box 2 needs to be fixedly set in the drawer body 1, the detergent box 2 is pushed inward, and a slight negative pressure is formed in the adsorption chamber 31 through the operation of the micro vacuum pump, and the detergent box 2 is adsorbed in the drawer body 1 through the slight negative pressure. Without departing from the basic principles of the present application, those skilled in the art can flexibly select the specific setting form of the pressure regulating part 33 according to the specific application scenario, as long as the pressure regulating part 33 can form a slight negative pressure in the adsorption chamber 31 when the detergent box 2 is closed relative to the drawer body 1, and can connect the adsorption chamber 31 with the external environment when the detergent box 2 is opened relative to the drawer body 1.

[0040] Although the above description is based on the example that the adsorption device 3 includes an adsorption chamber 31, a connecting portion 32, and a pressure regulating portion 33, it is obvious that other settings are also possible. For example, the adsorption device 3 includes an electromagnet and an iron sheet. When the electromagnet is powered on, it has magnetism and can adsorb the iron sheet. When the electromagnet is powered off, the magnetism disappears and the iron sheet is no longer adsorbed, etc. Without deviating from the basic requirements of the present application, those skilled in the art can flexibly select the specific setting form of the adsorption device 3 according to the specific application scenario, as long as it can generate an adsorption force between the drawer body 1 and the detergent box 2, or release the adsorption effect between the drawer body 1 and the detergent box 2 as needed.

[0041] It should be noted that the side of the adsorption chamber 31 away from the connection part 32 can also be connected to the detergent box 2, that is, the adsorption chamber 31 is arranged in the detergent box 2, and the connection hole 21 is arranged in the drawer body 1. Without departing from the basic principle of the present application, those skilled in the art can flexibly select the setting positions of the adsorption chamber 31 and the connection hole 21 according to specific application scenarios, as long as the connection part 32 can be matched with the connection hole 21 and a slight negative pressure can be formed in the adsorption chamber 31 when the detergent box 2 is closed relative to the drawer body 1, thereby forming an adsorption force between the detergent box 2 and the drawer body 1.

[0042] It should be noted that the connection hole 21 may also be provided in other ways. For example, the left end of the detergent box 2 extends leftwards by a connection column, and the connection hole 21 is formed by the connection column being recessed inwards.

[0043] It should be noted that, in the above embodiment, the two ends of the detergent box 2 refer to the two ends of the detergent box 2 arranged in the horizontal direction, that is, the end of the detergent box 2 close to the drawer body 1 is the left end of the detergent box 2, and the end of the detergent box 2 away from the drawer body 1 is the right end of the detergent box 2.

[0044] like Figures 1 to 3 As shown, the first valve stem 3311 is also provided with a first protrusion 3313, and the first protrusion 3313 is substantially provided on the first valve stem 3311 along its length direction (roughly Figure 3 The first protrusion 3313 is arranged in the middle of the first valve stem 3311 (in the vertical direction) and along the circumference of the first valve stem 3311. The first protrusion 3313 is generally an inverted cone structure. The second valve stem 3321 is also provided with a second protrusion 3323. The second protrusion 3323 is generally arranged at the middle of the second valve stem 3321 along its length direction (approximately Figure 3The second protrusion 3323 is arranged in the middle of the adsorption chamber 31 (in the vertical direction) and along the circumference of the second valve stem 3321, and the second protrusion 3323 is roughly an inverted cone structure. When the first adjusting member 331 and the second adjusting member 332 are installed, the first protrusion 3313 is located inside the adsorption chamber 31, and the second protrusion 3323 is located outside the adsorption chamber 31. In other words, the first protrusion 3313 and the first valve cap 3312 are respectively located on both sides of the upper side wall of the adsorption chamber 31, and the second protrusion 3323 and the second valve cap 3322 are respectively located on both sides of the lower side wall of the adsorption chamber 31. When the first adjusting member 331 and the second adjusting member 332 are upward, the upper surface of the first protrusion 3313 will abut against the inner surface of the upper side wall of the adsorption chamber 31, and the second protrusion 3323 will abut against the outer surface of the lower side wall of the adsorption chamber 31, so that it can ensure that the air can be discharged from the adsorption chamber 31 through the gap between the first valve stem 3311 and the first through hole to generate an adsorption force between the detergent box 2 and the drawer body 1, thereby making the detergent box 2 continuously in the drawer body 1, or ensure that the air can enter the adsorption chamber 31 through the gap between the second valve stem 3321 and the second through hole to release the adsorption effect between the detergent box 2 and the drawer body 1, thereby making the user more easily able to pull the detergent box 2 out of the drawer body 1, and the first adjusting member 331 and the second adjusting member 332 will not be disengaged from the first through hole and the second through hole due to the excessive upward displacement of the first adjusting member 331 and the second adjusting member 332, thereby ensuring that the adsorption device 3 works long-term and effectively, thereby improving the user experience.

[0045] It should be noted that, when viewed in the vertical direction, the first protrusion 3313 and the second protrusion 3323 may also be arranged at the bottom end of the first valve stem 3311 and the second valve stem 3321, or at a position close to the bottom end. Obviously, the first protrusion 3313 and the second protrusion 3323 may not be arranged along the circumference of the first valve stem 3311 and the second valve stem 3321, but may be arranged as a convex block, or may be composed of a plurality of convex blocks arranged along the circumference of the first valve stem 3311 and the second valve stem 3321. Of course, the first valve stem 3311 may not be provided with the first protrusion 3313, and the second valve stem 3321 may not be provided with the second protrusion 3323. In this case, the first valve stem 3311 and the second valve stem 3321 may be arranged as a structure with gradually increasing radial dimensions from top to bottom. Without departing from the basic principles of the present application, technicians in this field can flexibly select the specific setting method of the first valve stem 3311 and the second valve stem 3321 according to the specific application scenario, as long as the first adjusting member 331 and the second adjusting member 332 do not fall out of the first through hole and the second through hole when moving upward, ensuring that the first adjusting member 331 and the second adjusting member 332 are always matched with the adsorption chamber 31.

[0046] In a possible implementation, the first adjusting member 331 and the second adjusting member 332 are made of an elastomeric material, so that the first adjusting member 331 and the second adjusting member 332 prepared in this way are both elastic. When the detergent box 2 is closed relative to the drawer body 1, due to the extrusion of the connecting portion 32, the pressure in the adsorption chamber 31 is reduced, forming a slight negative pressure. In this case, the first adjusting member 331 and the second adjusting member 332 are respectively tightly fitted with the outer wall and the inner wall of the adsorption chamber 31, so that the adsorption chamber 31 is completely isolated from the outside, so that the slight negative pressure state can be better maintained in the adsorption chamber 31, and the detergent box 2 is stably adsorbed in the drawer body 1, so as to prevent the detergent box 2 from moving out of the drawer body 1 due to the vibration of the drum washing machine.

[0047] It should be noted that the elastomer material includes thermosetting elastomer materials and thermoplastic elastomer materials, such as styrene-based thermoplastic elastomer materials, styrene-isoprene-styrene (SIS) block copolymers, EPDM rubber, thermoplastic EPDM dynamic vulcanized rubber, polypropylene, block copolymers containing polyester hard segments and polyether soft segments, etc. Obviously, the first adjusting member 331 and the second adjusting member 332 may not be made of elastomer materials, but may be made of a lighter material (such as aluminum), and then a sealing member 4 made of rubber is provided on the side thereof facing the adsorption chamber 31, so that a slight negative pressure can be formed in the adsorption chamber 31 when the connecting portion 32 moves into the connecting hole 21. Without departing from the basic principles of the present application, technicians in this field can flexibly select the specific types of materials for preparing the first adjusting member 331 and the second adjusting member 332 according to the specific application scenario, as long as the movement of the first adjusting member 331 and the second adjusting member 332 can form a slight negative pressure in the adsorption chamber 31, or connect the adsorption chamber 31 to the external environment.

[0048] like Figures 1 to 3 As shown, the drawer assembly also includes a seal 4, which is roughly an annular sealing ring. A groove 321 is provided near the right end of the connecting portion 32, and the groove 321 is an annular groove provided along the circumference of the connecting portion 32. The seal 4 is clamped in the groove 321. When installed, the seal 4 is clamped between the inner wall of the connecting hole 21 and the connecting portion 32, and abuts against the inner wall of the connecting hole 21, so that the sealing between the connecting portion 32 and the connecting hole 21 is achieved. Through such a setting, it can be ensured that the adsorption chamber 31, the chamber formed by the connection between the connecting portion 32 and the connecting hole 21 are completely isolated from the external environment to form a relatively closed space, and the friction between the connecting portion 32 when the connecting portion 32 moves in the connecting hole 21 can be reduced, thereby ensuring that the connecting portion 32 can move smoothly in the connecting hole 21.

[0049] It should be noted that the seal 4 can also be a long strip of sealing strip. When installing, the sealing strip can be clamped into the groove 321 to achieve the sealing between the connecting hole 21 and the connecting part 32. Obviously, the groove 321 may not be provided on the connecting part 32, and the seal 4 can be directly sleeved on the outer wall of the connecting part 32. Obviously, the seal 4 may not be provided on the connecting part 32, but may be provided on the inner wall of the connecting hole 21 by bonding, clamping, etc. Without departing from the basic principles of the present application, those skilled in the art can flexibly select the specific setting form of the seal 4 according to the specific application scenario, as long as it can ensure the sealing between the connecting part 32 and the connecting hole 21.

[0050] Obviously, the drawer assembly may also not include the seal 4, but by making the outer diameter of the connecting part 32 roughly the same as the inner diameter of the connecting hole 21, the outer wall of the connecting part 32 abuts against the inner wall of the connecting hole 21 when installed to ensure the seal between the connecting part 32 and the connecting hole 21.

[0051] To sum up, in the preferred technical scheme of the present invention, through the arrangement of the adsorption device 3, when the detergent box 2 is closed relative to the drawer body 1, an adsorption force can be generated between the drawer body 1 and the detergent box 2, and the detergent box 2 can be adsorbed in the drawer body 1. Even if the drum washing machine vibrates, the detergent box 2 will not move to the outside of the drawer body 1. When it is necessary to replace or add clothing treatment agent, the adsorption effect between the drawer body 1 and the detergent box 2 can be released, and the user can easily pull out the detergent box 2, thereby effectively improving the user experience. By making the adsorption device 3 include an adsorption chamber 31, a connection part 32 and a pressure regulating part 33, making the connection part 32 inserted into the connection hole 21 from the opening end 211 of the connection hole 21, and making the pressure regulating part 33 include a first regulating member 331 and a second regulating member 332, when the detergent box 2 is closed relative to the drawer body 1, a slight negative pressure can be formed in the adsorption chamber 31, thereby generating an adsorption force between the detergent box 2 and the drawer body 1, and when the detergent box 2 is opened relative to the drawer body 1, the adsorption chamber 31 can be connected to the external environment, thereby releasing the adsorption effect between the detergent box 2 and the drawer body 1. By arranging a sealing member 4 between the inner wall of the connection hole 21 and the connection part 32, it is possible to ensure that the adsorption chamber 31, the chamber formed by the connection between the connection part 32 and the connection hole 21 are completely isolated from the external environment without affecting the movement of the connection part 32 relative to the connection hole 21, thereby better ensuring the formation of a slight negative pressure in the adsorption chamber 31, and better positioning the detergent box 2 in the drawer body 1.
