Description

Technical Field

[0001] The present invention belongs to the technical field of household appliances, and more specifically, relates to a laundry treatment device. Background Art

[0002] In laundry treatment devices, it is often necessary to add liquids such as detergents to improve the washing degree of clothes. In related technologies, the detergents and other liquids are replenished in a liquid adding device, and the liquid adding device is connected to the workbench of the laundry treatment device, so that the detergents in the liquid adding device flow into the interior of the laundry treatment device along the fluid channel in the workbench. Among them, the connection relationship between the liquid adding device and the workbench is determined by a switching device. The related switching device is internally provided with a flow channel for the detergent to pass through. The switching device can control the flow channel therein to be connected or disconnected from the liquid adding device and the workbench. Therefore, the efficiency of the detergent flowing is limited by the size of the internal flow channel of the switching device, resulting in a slow liquid adding speed. Summary of the Invention

[0003] In view of this, the present invention provides a laundry treatment device to solve the technical problem of how to improve the liquid adding efficiency of the liquid adding device.

[0004] The technical solution of the present invention is realized as follows:

[0006] In some embodiments, the switching assembly includes: a fixing member, arranged inside the accommodating cavity, and the fixing member is used for fixedly connecting the switching assembly to the body.

[0007] In some embodiments, the outer diameter of the fixing member is greater than the outer diameter of the liquid outlet channel.

[0008] In some embodiments, the liquid inlet channel is sleeved on the outer wall of the pipe body to realize the installation between the workbench and the liquid adding device.

[0009] In some embodiments, the switch assembly further includes: an elastic member extending along a first direction and having one end connected to the fixing member; a movable member connected to the other end of the elastic member, and the end of the movable member away from the elastic member is used to abut against the ejector pin; the movable member can move relative to the fixing member along the first direction to open and close the liquid outlet.

[0010] In some embodiments, the movable member includes: a shielding portion abutting against the other end of the elastic member, the shielding portion extending along a second direction, and the second direction is perpendicular to the first direction; a supporting portion connected to the shielding portion and extending along the first direction and used to abut against the ejector pin; wherein, the supporting portion drives the shielding portion to reciprocate along the first direction under the push of the elastic member and / or the ejector pin to open and close the liquid outlet.

[0011] In some embodiments, the switch assembly further includes: a first sealing member disposed in close fit with the side of the shielding portion close to the liquid outlet to seal the shielding portion and the liquid outlet in a state where the shielding portion shields the liquid outlet.

[0012] In some embodiments, the bottom surface of the first sealing member away from the shielding portion is a plane extending along the second direction.

[0013] In some embodiments, the bottom surface of the first sealing member away from the shielding portion is provided as a curved surface protruding in a direction close to the shielding portion.

[0014] In some embodiments, the portion of the first sealing member in close fit with the shielding portion covers the circumferential edge of the shielding portion.

[0015] In some embodiments, the supporting portion penetrates through the shielding portion, and the supporting portion includes a first supporting portion and a second supporting portion located on both sides of the shielding portion. The elastic member is sleeved on the first supporting portion, and the second supporting portion is disposed in the liquid outlet channel, and the second supporting portion is used to move in a direction close to the fixing member under the push of the ejector pin.

[0016] In some embodiments, it further includes: a guide ring disposed in the liquid outlet channel and fixedly connected to the pipe body; wherein, the second supporting portion passes through the guide ring and is movably connected to the guide ring.

[0017] In some embodiments, the ratio of the outer diameter of the second supporting portion in the second direction to the diameter of the liquid outlet is less than or equal to 0.3.

[0018] In some embodiments, the fixing member includes: a top wall extending in a second direction and connected to one end of the elastic member; a side wall disposed around the edge of the top wall and along a first direction; wherein, the liquid adding device has a connecting portion extending from the liquid outlet into the accommodating cavity, and the connecting portion is detachably connected to the side wall.

[0019] In some embodiments, a first convex portion protruding along the first direction is provided on a side of the top wall close to the elastic member, and the connecting portion of the liquid adding device is located between the first convex portion and the side wall and abuts against the first convex portion.

[0020] In some embodiments, a second convex portion protruding along the first direction is further provided on a side of the top wall close to the elastic member, the second convex portion is located inside the first convex portion, and one end of the elastic member is sleeved on the second convex portion.

[0022] In the embodiment of the present invention, by disposing the switch assembly inside the liquid adding device, when the liquid adding device is installed on the workbench, the top post can push the switch assembly to open the liquid outlet of the liquid adding device, so that the liquid in the liquid adding device flows into the liquid inlet channel of the workbench through the liquid outlet channel of the liquid adding device, and the liquid does not flow through the inside of the switch assembly during the flowing process. Therefore, the flow rate of the liquid is not limited by the size of the switch assembly, which is beneficial to improving the liquid adding efficiency of the liquid adding device.

[0023] In some scenarios, when the liquid adding device is cooperatively installed with the workbench, the inner diameter of the liquid inlet channel of the workbench needs to consider the outer diameter of the liquid outlet channel. In the prior art, a fixing member for fixing the switch assembly is provided on the outside of the liquid outlet channel, and the radial dimensions of the fixing member are relatively large, resulting in that the determination of the inner diameter of the liquid inlet channel of the workbench not only depends on the outer diameter of the liquid outlet channel, but also needs to consider the outer diameter of the fixing member, so that the inner diameter of the liquid inlet channel of the workbench is much larger than the outer diameter of the liquid outlet channel, and finally the effective cross-sectional area for liquid flow in the liquid inlet channel is significantly reduced.

[0024] In the clothing treatment device provided in the present application, the fixing member of the switch assembly is disposed in the accommodating cavity of the liquid adding device. When the liquid adding device is cooperated with the workbench, the inner diameter of the liquid inlet channel only relates to the outer diameter of the liquid outlet channel and does not need to consider the radial dimension of the fixing member. Therefore, the inner diameter of the liquid inlet channel only needs to be slightly larger than the outer diameter of the liquid outlet channel. When the liquid flows from the liquid outlet channel of the liquid adding device into the liquid inlet channel of the workbench, the liquid inlet channel is almost filled with the liquid, and the effective flow cross-sectional area of the liquid inlet channel in the workbench is effectively improved.

[0040] Such as Figure 1As shown, a laundry treatment device needs to dispense detergent to improve the cleaning degree of clothes. The liquid adding device 1 is used to contain liquids such as detergent and fabric softener. The liquid adding device 1 is installed in the laundry treatment device so that the detergent can automatically flow into the laundry treatment device. When the detergent in the liquid adding device 1 is exhausted, the liquid adding device 1 can be detached from the laundry treatment device and the detergent can be replenished into the liquid adding device 1. The related liquid adding device 1 includes a containing cavity 11 for containing liquid. A switch assembly 2 is provided at the outlet of the liquid adding device 1, that is, a part of the switch assembly 2 is located inside the liquid adding device 1 and a part is located outside the outlet of the liquid adding device 1. The switch assembly 2 has a channel inside. The liquid in the containing cavity 11 can flow out through the channel inside the switch assembly 2. The switch assembly 2 can move to connect or block the connection between its internal channel and the containing cavity. The liquid in the related liquid adding device flows out through the channel inside the switch assembly, and the flow rate of the liquid is affected by the structural dimensions of the switch assembly, resulting in a relatively low liquid outflow rate.

[0041] An embodiment of the present invention provides a laundry treatment device capable of improving the liquid adding efficiency. As Figure 2 shown, the laundry treatment device includes a liquid adding device 1, a switch assembly 2, and a workbench 6.

[0042] Combined with Figure 2 and Figure 3 shown, the liquid adding principle of the laundry treatment device will be described below:

[0043] An inlet channel 4 and a mixing cavity 8 are provided inside the workbench 6 in the laundry treatment device. The inlet channel 4 is connected to the mixing cavity 8 through a dosing pump 7. Figure 2 The arrow direction shown in Figure 2 represents the direction of liquid flow. When the liquid adding device 1 is installed on the workbench 6, the liquid adding device 1 is communicated with the inlet channel 4 inside the workbench 6. The ejector pin 5 inside the inlet channel 4 can push the switch assembly 2 so that the liquid in the liquid adding device 1 can flow into the inlet channel 4. The dosing pump 7 can control the liquid in the inlet channel 4 to enter the mixing cavity 8. For example, when receiving an instruction to add liquid, the dosing pump 7 absorbs the liquid in the inlet channel 4 and discharges it into the mixing cavity 8. The discharged liquid can be mixed with the water in the mixing cavity 8 to form a dilution liquid, and the dilution liquid flows into the washing tub (

[0044] Combined with Figures 2 - 3As shown in the figure, the liquid adding device 1 in the embodiment of the present invention is detachably connected to the workbench 6, and the switch assembly 2 is movably connected to the liquid adding device 1. When the liquid adding device 1 is connected to the workbench 6, the ejector pin 5 in the liquid inlet channel 4 can push the switch assembly 2, so that the liquid adding device 1 is communicated with the liquid inlet channel 4; when the liquid adding device 1 is separated from the workbench 6, the switch assembly 2 closes the liquid adding device 1, so that the liquid in the liquid adding device 1 will not flow out.

[0045] As Figure 4 shown in the figure, the liquid adding device 1 in the embodiment of the present invention includes a main body 10 and a tube body 16. Among them, the main body 10 and the tube body 16 are integrally connected. The connection method can be that the tube body 16 and the main body 10 are integrally formed. The cross-sectional area of the main body 10 is much larger than that of the tube body 16. It can be understood that the tube body 16 is arranged in the form of a channel with a smaller diameter to connect the main body 10 with a larger diameter.

[0046] As Figure 4 shown in the figure, a receiving cavity 11 and a liquid outlet 12 are provided inside the main body 10. The receiving cavity 11 is used to hold liquid. Among them, the receiving cavity 11 in the embodiment of the present invention can be used to hold liquids with cleaning functions such as detergents, fabric softeners, and disinfectants. The liquid outlet 12 is communicated with the receiving cavity 11. It can be understood that the liquid outlet 12 is the opening liquid outlet of the receiving cavity 11; a through liquid outlet channel 161 is provided inside the tube body 16, and the liquid outlet channel 161 is communicated with the liquid outlet 12; that is: the liquid outlet 12 is the interface between the receiving cavity 11 and the liquid outlet channel 161.

[0047] As Figure 4 shown in the figure, the switch assembly 2 is arranged inside the liquid adding device 1, and at least part of the switch assembly 2 is arranged inside the receiving cavity 11. For example, as Figure 4 shown in the embodiment, part of the switch assembly 2 can also be arranged inside the receiving cavity 11, and the other part can be arranged inside the liquid outlet channel 161; in some other embodiments, the switch assembly 2 can also be completely arranged inside the receiving cavity 11.

[0048] Among them, when Figure 4 the shown liquid adding device 1 is not installed on the workbench 6 of the laundry treatment device, the switch assembly 2 closes the liquid outlet 12, and the liquid in the receiving cavity 11 cannot flow into the liquid outlet channel 161. When Figure 3 the shown liquid adding device 1 is installed on the workbench 6 of the laundry treatment device, the ejector pin 5 in the liquid inlet channel 4 abuts against the lower part of the switch assembly 2 and pushes the switch assembly 2 to move upward, thereby opening the liquid outlet 12, so that the liquid in the receiving cavity 11 can flow into the liquid outlet channel 161 and further into the liquid inlet channel 4 of the workbench 6. Thus, the liquid adding device remains in a normally closed non-liquid discharging state when not installed on the workbench, and remains in a normally open liquid discharging state when installed on the workbench.

[0049] A laundry treatment device according to an embodiment of the present invention, the laundry treatment device includes a liquid adding device, a switch assembly and a workbench. The liquid adding device includes a main body and a pipe body. An accommodation cavity and a liquid outlet are provided in the main body. A liquid outlet channel is provided in the pipe body. The liquid outlet channel is connected to the liquid outlet. The switch assembly is arranged in the liquid adding device, and the switch assembly is movably connected to the liquid adding device to open and close the liquid outlet. An inlet channel is provided in the workbench, and a top column is provided in the inlet channel. The pipe body can extend into the inlet channel, so that the top column pushes the switch assembly to open the liquid outlet. By arranging the switch assembly in the liquid adding device in the embodiment of the present invention, when the liquid adding device is installed on the workbench, the top column can push the switch assembly to open the liquid outlet of the liquid adding device, so that the liquid in the liquid adding device flows into the inlet channel of the workbench through the liquid outlet channel of the liquid adding device. During the liquid flow process, the liquid does not pass through the inside of the switch assembly. Therefore, the flow rate of the liquid will not be limited by the size of the switch assembly, which is beneficial to improving the liquid adding efficiency of the liquid adding device.

[0050] In some embodiments, as Figure 4 shown, the main body 10 includes an end cover 101 and a side wall 102. The side wall 102 encloses an accommodation cavity 11 with an open upper end. The end cover 101 is detachably connected to the side wall 102. When the end cover 101 is separated from the side wall 102, the upper end of the accommodation cavity 11 ( Figure 4 the upper end shown) is open, and the user can supplement the liquid into the accommodation cavity 11 from the open side. When the end cover 101 is connected to the side wall 102, the end cover 101 closes the accommodation cavity 11, so that the accommodation cavity 11 is separated from the outside of the main body 10. Among them, the liquid outlet through which the liquid flows out of the accommodation cavity 11 can be arranged at the bottom of the main body 10 opposite to the end cover 101.

[0051] In the embodiment of the present invention, through the detachable connection mode of the end cover and the side wall, the liquid can be supplemented from the upper end of the main body 10, and the liquid flows out from the lower end of the main body. The functions of liquid inlet and outlet in the main body are distinguished, and the operations of liquid inlet and outlet do not interfere with each other. When the liquid in the accommodation cavity is used up, the detergent can be supplemented by opening the end cover, so that the main body can be recycled multiple times, reducing costs, saving energy and protecting the environment.

[0052] In some embodiments, as Figure 5 shown, the switch assembly 2 includes a fixing member 21. Among them, as Figure 4 shown, the fixing member 21 is arranged in the accommodation cavity 11. The fixing member 21 is fixedly connected to the main body 10. Specifically, the fixing member 21 is fixedly connected to the side of the main body 10 close to the accommodation cavity 11, so that the fixing member 21 can remain stationary relative to the accommodation cavity 11.

[0053] For the laundry treatment device provided in this application, the fixing member of the switch assembly is arranged in the accommodation cavity of the liquid adding device. When the liquid adding device cooperates with the workbench, the inner diameter of the liquid inlet channel is only related to the outer diameter of the liquid outlet channel, and the radial dimension of the fixing member does not need to be considered. Therefore, the inner diameter of the liquid inlet channel only needs to be slightly larger than the outer diameter of the liquid outlet channel. When the liquid flows from the liquid outlet channel of the liquid adding device into the liquid inlet channel of the workbench, the liquid inlet channel is almost filled with the liquid, and the effective flow cross-sectional area of the liquid inlet channel in the workbench is effectively increased.

[0054] The outer diameter of the fixing member 21 is larger than the outer diameter of the liquid outlet channel 161, which facilitates the vertical connection of the fixing member 21 and the main body 10, so as to avoid the bottom of the main body becoming an obstacle to liquid flow and improve the liquid inlet efficiency. Specifically: Refer to Figure 4 ., only when the fixing member 21 is larger than the outer diameter of the liquid outlet channel 161, it is possible to achieve the vertical connection between the fixing member and the main body. And the vertical connection between the fixing member and the main body is beneficial to the situation that when the switch assembly opens the liquid outlet, the main body will not become an obstacle to the liquid flowing from the accommodation cavity to the liquid outlet. If the fixing member 21 is smaller than the outer diameter of the liquid outlet channel 161, the bottom end of the main body needs to be inclined towards the direction close to the fixing member, and the inclined main body will surely become an obstacle to the liquid flowing from the accommodation cavity to the liquid outlet. Moreover, if the fixing member 21 is smaller than the outer diameter of the liquid outlet channel 161, then the caliber of the liquid flowing from the accommodation cavity into the liquid outlet channel will become smaller, and together with the obstacle of the inclined main body, the liquid flow efficiency will be greatly reduced finally. Therefore, in this application, the fixing member 21 is arranged in the accommodation cavity, and the outer diameter of the fixing member is larger than the outer diameter of the liquid outlet channel, which is beneficial to improving the fluid flow efficiency.

[0055] As Figure 6 shown, the liquid adding device is installed on the workbench, and the liquid inlet channel 4 is sleeved on the outer wall of the pipe body 16.

[0056] As Figure 5 shown, the switch assembly 2 further includes: an elastic member 22 and a movable member 23. Among them, the elastic member 22 extends along the first direction ( Figure 4 the up and down direction shown), and the extending direction represents the maximum dimension direction of the outer contour of the elastic member 22, that is, the length direction of the elastic member. The elastic member 22 has opposite ends in the length direction. Among them, one end of the elastic member 22 is connected to the fixing member 21, and the other end of the elastic member 22 is connected to the movable member 23. The connection method between the elastic member 22 and the fixing member 21 can be a detachable connection such as snap connection or threaded connection, or a permanent fixed connection such as welding. The other end of the elastic member 22 is connected to the movable member 23.

[0057] Combined with Figure 5 and Figure 6 shown, the working principle of the switch assembly is described as follows:

[0058] As Figure 5 shown, when the liquid adding device is not installed on the workbench, correspondingly, the pipe body 16 does not extend into the liquid inlet channel of the workbench. In this state, the elastic member 22 is in a state of generating a downward thrust on the movable member 23. Under the elastic force of the elastic member 22, the movable member 23 abuts against the liquid outlet 12 between the accommodating cavity 11 and the liquid outlet channel 161, so that the liquid outlet 12 is closed, and the liquid in the accommodating cavity 11 cannot flow out from the liquid outlet 12.

[0059] As Figure 6 shown, during the process of installing the liquid adding device on the workbench, the liquid adding device is inserted downward into the workbench. During this process, the movable member 23 moves towards the top column 5 until it abuts against the top column 5. Since the movable member 23 abuts against the top column 5, the movable member 23 is pushed upward by the upward thrust of the top column 5 and moves upward away from the liquid outlet 12. At the same time, the elastic member 22 is continuously compressed during the upward movement of the movable member 23. During the upward movement of the movable member 23, the movable member 23 changes from the state of being sealed with the liquid outlet 12 ( Figure 5 the state shown) to the state where the movable member 23 opens the liquid outlet 12 ( Figure 6 the state shown), and the gap between the movable member 23 and the liquid outlet 12 gradually increases to the maximum value. In the state where the liquid outlet 12 is open, the liquid in the accommodating chamber 11 can flow from the liquid outlet 12 to the liquid outlet channel 161, and then flow into the liquid inlet channel 4 of the workbench. The flow rate of the liquid flowing into the liquid inlet channel 4 is determined according to the diameter dimensions of the liquid outlet 12 and the liquid outlet channel 161 and is not limited by the internal dimensions of the switch assembly, thereby improving the liquid adding efficiency of the liquid adding device.

[0060] As Figure 5 shown, during the process of removing the liquid adding device from the workbench, the liquid adding device is separated from the workbench, and the movable member 23 moves in the direction away from the top column 5 ( Figure 6 the upward direction shown). When the movable member 23 is separated from the top column 5, the movable member 23 does not receive the upward thrust exerted by the top column 5, and the elastic member 22 exerts a downward force on the movable member 23, so that the movable member 23 returns to the state of closing the liquid outlet 12.

[0061] In some embodiments, as Figure 5 shown, the movable member 23 includes a shielding portion 231 and a supporting portion 232. The shielding portion 231 abuts against one end of the elastic member 22 ( Figure 5 the lower end shown). The shielding portion 231 extends along the second direction ( Figure 5extends in the left - right direction (as shown), and the second direction is perpendicular to the first direction. In the state where the liquid - adding device is separated from the workbench, the shielding portion 231 is not pushed by the ejector pin 5, and under the elastic force of the elastic member 22, the shielding portion 231 abuts against the main body 10 to close the liquid outlet 12.

[0062] As Figure 6 shown, when the liquid - adding device is installed on the workbench, the shielding portion 231 is under the thrust of the ejector pin 5. The shielding portion 231 moves upward away from the liquid outlet 12 and compresses the elastic member 22, thereby opening the liquid outlet 12. The liquid in the accommodating cavity 11 flows from the gap between the shielding portion 231 and the liquid outlet 12 to the liquid outlet 12, then flows to the liquid outlet passage 161, and flows from the liquid outlet passage 161 to the liquid inlet passage 4 inside the workbench.

[0063] As Figure 5 shown, the support portion 232 is connected to the shielding portion 231 and extends along the first direction. The support portion 232 can be a rod - shaped structure. It can be understood that the length direction of the support portion 232 is defined as the first direction ( Figure 5 shown in the up - down direction), and at least part of the support portion 232 is arranged in the liquid outlet passage 161. During the process of installing the liquid - adding device on the workbench, compared with the shielding portion 231, the ejector pin 5 can contact the support portion 232 first. By pushing the support portion 232 to move in the first direction ( Figure 5 shown in the up - down direction), the support portion 232 drives the shielding portion 231 to move away from the liquid outlet 12, thereby realizing the opening of the liquid outlet 12 by the shielding portion 231. During the process of removing the liquid - adding device from the workbench, the thrust force of the ejector pin 5 acting on the support portion 232 gradually decreases. The elastic member 22 can recover its deformation under the elastic force, and the elastic force can push the shielding portion 231 and the support portion 232 to move towards the liquid outlet 12 until the support portion 232 is completely separated from the ejector pin 5, and the shielding portion 231 returns to the position of shielding the liquid outlet 12 under the elastic force.

[0064] In the embodiment of the present invention, by providing a support portion extending along the first direction on the shielding portion, the switch assembly is arranged in a T - shaped structure. On the one hand, it can make the elastic member easily wound around the support portion. On the other hand, the cross - sectional area of the support portion can be set to match the cross - sectional area of the ejector pin in the liquid inlet passage, so that the ejector pin can easily contact the switch assembly, reducing the difficulty of switching between the two working states of the switch assembly and improving the smoothness of the operation of the liquid - adding device.

[0065] In some embodiments, as Figure 5 shown, the support portion 232 is in the second direction ( Figure 5The ratio of the outer diameter M1 in the left-right direction (as shown) to the diameter M2 of the liquid outlet 12 is less than or equal to 0.3. The area of the shielding portion 231 in the second direction is larger than the area of the liquid outlet 12. In the state where the liquid adding device is separated from the workbench, the shielding portion 231 can close the liquid outlet 12, so that the liquid in the accommodating cavity 11 cannot flow to the liquid outlet passage 161 through the liquid outlet 12.

[0066] In the embodiment of the present invention, by limiting the ratio of the radial dimension of the support portion to the liquid outlet within a certain range, the support portion can not only achieve the transmission of external force, but also not occupy too much space at the position of the liquid outlet, so as to improve the liquid guiding efficiency of the liquid outlet.

[0067] In some embodiments, such as Figure 5 shown, the support portion 232 penetrates through the shielding portion 231. The support portion 232 includes a first support portion 2321 and a second support portion 2322 located on both sides of the shielding portion 231. Among them, the first support portion 2321 is arranged on the side of the shielding portion 231 close to the accommodating cavity 11, and the second support portion 2322 is arranged on the side of the shielding portion 231 away from the accommodating cavity 11. The elastic member 22 is sleeved on the first support portion 2321. In some implementations, the elastic member 22 can be set as a spring. The spring is hollow inside, and one end of the spring can be sleeved on the first support portion 2321, so that the first support portion 2321 can not only support the elastic member 22, but also limit the elastic member 22, reducing the risk of the elastic member 22 moving in the second direction ( Figure 5 the left-right direction as shown). Adopting the connection method of the first support portion 2321 and the elastic member 22, its structure is simple and the installation is convenient, which is beneficial to improving the assembly speed. Such as Figure 6 shown, the second support portion 2322 is arranged in the liquid outlet passage 161. In the state where the liquid adding device is installed on the workbench, the second support portion 2322 can receive the thrust force of the ejector pin 5, and the second support portion 2322 can drive the shielding portion 231 and the first support portion 2321 to move.

[0068] In some embodiments, such as Figure 5 and Figure 6As shown, the switch assembly 2 further includes a first seal 24. The first seal 24 is disposed in contact with the side of the shielding portion 231 close to the liquid outlet 12. It can be understood that the first seal 24 is disposed in the accommodation cavity 11, the first seal 24 is connected to the shielding portion 231, and the first seal 24 can move following the movement of the shielding portion 231. In the state where the shielding portion 231 shields the liquid outlet 12, the first seal 24 is located between the liquid outlet 12 and the shielding portion 231, so that the shielding portion 231 and the liquid outlet 12 are sealed. It should be noted that the first seal 24 can be made of flexible materials such as silica gel and rubber. When the first seal 24 abuts against the liquid outlet 12, it will be extruded and deformed under the action of an external force, so that the first seal 24 is in close contact with the liquid outlet 12, thereby improving the sealing performance between the shielding portion 231 and the liquid outlet 12.

[0069] In some embodiments, as Figure 5 and Figure 6 shown, the bottom surface of the first seal 24 away from the shielding portion 231 ( Figure 5 the lower surface of the first seal 24 shown) is a plane extending in the second direction ( Figure 5 the left - right direction described). The plane means that all points on the bottom surface of the first seal 24 away from the shielding portion 231 are located on the same horizontal plane. In the normal use state, this horizontal plane can be used to represent the surface parallel to the horizontal direction in the absolute coordinate system.

[0070] In some embodiments, as Figure 8 shown, the bottom surface of the first seal 24 away from the shielding portion 231 ( Figure 8 the lower surface of the first seal 24 shown) is set as an arc surface, and the arc surface protrudes towards the direction close to the shielding portion 231. That is to say, the arc surface bends in the direction away from the shielding portion 231 (downward).

[0071] Among them, the arc surface means that the bottom surface of the first seal 24 does not extend along the set horizontal direction, but the points on the arc surface can extend in multiple directions. The first seal 24 in the embodiment of the present invention can be set as a flexible structure, that is to say, the first seal 24 can be deformed under the action of an external force. Combining Figure 8 shown, the radian of the arc surface of the first seal 24 in the embodiment of the present invention is not necessarily fixed at all times. For example, when the first seal 24 is not under the action of an external force, the arc surface of the first seal 24 presents a natural state, and the bending degree of the arc surface of the first seal 24 is larger; when the first seal 24 is under the action of an external force, the first seal 24 is deformed by being squeezed, so that the bending degree of the arc surface on the first seal 24 is reduced. The state of the first seal 24 will be described below in combination with the connection state between the liquid adding device 1 and the workbench 6:

[0072] AsFigure 9 As shown, when the liquid adding device is connected to the workbench, the ejector pin in the liquid inlet channel pushes the second support portion 2322 to move towards the accommodating cavity 11 ( Figure 9 as shown, moving upward), the first seal 24 moves away from the liquid outlet channel 161, so that the accommodating cavity 11 is communicated with the liquid outlet channel 161, and the liquid in the accommodating cavity 11 can flow to the liquid outlet channel 161; in the above state, the first seal 24 is separated from contact with the liquid outlet 12, and the peripheral edge of the first seal 24 is not squeezed by the wall surface around the liquid outlet 12, so that the first seal 24 presents a natural state with a large bending degree. During this process, the shielding portion 231 moves upward to squeeze the elastic member 22.

[0073] Combined with Figure 9 as shown, when the liquid adding device is disconnected from the workbench, the second support portion 2322 moves away from the accommodating cavity 11 ( Figure 8 as shown, moving downward), the shielding portion 231 moves towards the liquid outlet 12 under the action of the restoring force of the elastic member 22, and the first seal 24 follows the shielding portion 231 to move towards the liquid outlet 12 ( Figure 8 as shown, moving downward). After the first seal 24 contacts the liquid outlet 12, the restoring force of the elastic member 22 has not completely disappeared, and the restoring force continues to be transmitted to the first seal 24. The first seal 24 is squeezed and deformed under the combined action of the elastic force and the supporting force of the inner wall of the liquid adding device 1, so that the bending degree of the first seal 24 is reduced. Under the combined action of the restoring force of the elastic member 22 and the liquid in the accommodating cavity 11, the first seal 24 contacts the inner wall of the liquid adding device 1 more closely, reducing the gap between the first seal 24 and the inner wall of the liquid adding device 1, thereby improving the sealing performance of the liquid adding device when the liquid adding device is disconnected from the workbench and reducing the risk of liquid leakage in the accommodating cavity 11.

[0074] In some embodiments, as Figure 9 shown, the portion of the first seal 24 that fits with the shielding portion 231 covers the circumferential edge of the shielding portion 231. That is to say, the side of the first seal 24 close to the accommodating cavity 11 can be sleeved outside the shielding portion 231. By covering the circumferential edge of the shielding portion with the portion of the first seal that fits with the shielding portion in the embodiment of the present invention, the connection method between the first seal and the shielding portion is simplified, and the connection stability between the shielding portion and the first seal is also improved.

[0075] In some embodiments, as Figure 9As shown in the figure, the laundry treatment device further includes a guide ring 9, which is arranged in the liquid outlet channel 161 and fixedly connected to the pipe body 16. Among them, the inner wall surface of the pipe body 16 adjacent to the liquid outlet channel 161 is used to fix the guide ring 9. The embodiment of the present invention does not limit the connection manner between the guide ring 9 and the pipe body 16, as long as the guide ring 9 is fixed relative to the liquid outlet channel 161. As Figure 9 shown, the second support portion 2322 passes through the guide ring 9. The guide ring 9 can be regarded as an annular structure, and a through hole is provided inside the guide ring. The second support portion 2322 can pass through the through hole, and the second support portion 2322 is movably connected to the guide ring 9. That is to say, the outer diameter of the second support portion 2322 can be slightly smaller than the inner diameter of the guide ring 9, so that during the movement of the second support portion 2322, it can ensure free movement in the first direction ( Figure 9 shown, the up and down direction), and can also limit the sway of the second support portion 2322 in the circumferential direction ( Figure 9 shown, the left and right direction). The guide ring 9 plays a limiting role in the movement of the second support portion 2322, which is beneficial to improving the movement stability of the second support portion 2322.

[0076] In some embodiments, as Figure 5 shown, the fixing member 21 includes a top wall 211 and a side wall 212. The top wall 211 extends in the second direction ( Figure 5 shown, the left and right direction). It should be noted that the top wall 211 can be a continuous whole plane. For example, it can be a circular or quadrilateral plane; the top wall 211 can also be a smooth curved surface. However, regardless of the shape of the top wall 211, the top wall 211 is connected to one end of the elastic member 22.

[0077] The side wall 212 is arranged around the edge of the top wall 211 and extends in the first direction ( Figure 5 shown, the up and down direction). Of course, in other embodiments, the side wall 212 can also extend in other directions, as long as the extending direction of the side wall 212 faces the liquid outlet 12.

[0078] Combined with Figure 4As shown, the liquid adding device 1 has a connecting portion 15 extending from the liquid outlet 12 into the accommodating cavity 11, and the connecting portion 15 is detachably connected to the side wall 212 of the fixing member 21. It should be noted that detachable means that the connecting portion 15 can maintain the relative position relationship with the side wall 212 unchanged in the fixed connection state, and the connecting portion 15 and the side wall 212 can be separated from the fixed connection state, that is, when an external force is applied to the switch assembly 2 by the user, the switch assembly 2 can be separated from the liquid adding device 1, and correspondingly, the connecting portion 15 is also separated from the side wall 212. Among them, the connection method between the connecting portion 15 and the side wall 212 includes but is not limited to threaded connection and snap connection, etc. The embodiments of the present invention do not limit the specific connection method between the connecting portion 15 and the side wall 212, as long as the connecting portion 15 and the side wall 212 are detachable.

[0079] It should be noted that, as Figure 4 shown, one end of the connecting portion 15 is connected to the part of the liquid adding device 1 close to the liquid outlet 12, and the connecting portion 15 can be integrally formed around the circumference of the liquid outlet 12. The connecting portion 15 can also be provided in multiple numbers, and the multiple connecting portions 15 are arranged at intervals in the circumferential direction of the liquid outlet 12. Figure 4 In the embodiment shown, two connecting portions 15 are provided, and the two connecting portions 15 are symmetrically arranged on both sides of the liquid outlet 12. The setting forms of the connecting portion 15 in the embodiments of the present invention include but are not limited to the above several. By providing more connecting portions 15 in the liquid adding device 1 and directly connecting the connecting portion 15 to the fixing member 21, the connection stability between the fixing member 21 and the liquid adding device 1 can be improved.

[0080] In the embodiments of the present invention, by detachably connecting the liquid adding device and the fixing member through the side wall and the connecting portion, the fixing member can be detached relative to the liquid adding device, which reduces the manufacturing difficulty of the entire liquid adding device, reduces the production cost, and is also beneficial to the disassembly, assembly and maintenance of the switch assembly.

[0081] In some embodiments, as Figure 4 shown, a convex portion 151 is provided at one end of the connecting portion 15 away from the liquid outlet 12, and a card slot 2121 is provided on the side wall of the fixing member 21. The convex portion 151 can be snapped into the card slot 2121 to realize the connection between the connecting portion 15 and the fixing member 21; under the action of an external force, the convex portion 151 can be separated from the card slot 2121, so that the connecting portion 15 is separated from the fixing member 21.

[0082] In some embodiments, as Figure 5 shown, on the side of the top wall 211 of the fixing member 21 close to the elastic member 22, it is arranged along the first direction ( Figure 5a first convex portion 213 protruding in the up-down direction (as shown). The first convex portion 213 can be arranged along the circumferential direction of the top wall 211, and the extending direction of the first convex portion 213 can be substantially parallel to the extending direction of the side wall 212. It should be noted that substantially parallel includes the case where the included angle between the extending direction of the first convex portion 213 and the extending direction of the side wall 212 is not strictly 0 degrees. It can be considered that the included angle between the two directions is less than 10 degrees, which belongs to substantially parallel, so as to cover the cases of processing and installation errors.

[0083] As Figure 5 shown, the first convex portion 213 and the side wall 212 are spaced apart in the second direction ( Figure 5 shown left-right direction). The connecting portion 15 of the liquid adding device 1 is located between the first convex portion 213 and the side wall 212, and the connecting portion 15 can abut against the first convex portion 213. In the embodiment of the present invention, by providing the first convex portion on the top wall, during the process of connecting the connecting portion to the fixing portion, the connecting portion can be limited between the first convex portion and the side wall, which helps to reduce the assembly difficulty, and thus can improve the assembly efficiency of the fixing member and the liquid adding device.

[0084] In some embodiments, as Figure 5 shown, on the side of the top wall 211 close to the elastic member 22, a second convex portion 214 protruding in the first direction ( Figure 5 shown up-down direction) is further provided. The second convex portion 214 is located inside the first convex portion 213. The second convex portion 214 and the top wall 211 can enclose an open cavity 2141. One end of the elastic member 22 can be sleeved outside the second convex portion 214, and one end of the elastic member 22 can be arranged in the cavity 2141. In the embodiment of the present invention, the specific connection form between the second convex portion 214 and the elastic member 22 is not limited, as long as the second convex portion 214 can play a role in connecting and limiting the elastic member 22.

[0085] In some embodiments, as Figure 6 shown, the second support portion 2322 can extend into the liquid outlet channel 161. During the process of inserting the pipe body 16 into the laundry treatment device, the second support portion 2322 in the pipe body 16 can first contact the top column 5 in the liquid inlet channel 4 of the workbench. The top column 5 contacts the second support portion 2322 and applies an upward thrust, so that the liquid outlet 12 is opened, realizing automatic liquid discharge when the liquid adding device is installed on the laundry treatment device.

[0086] In some embodiments, as Figure 5 shown, the liquid adding device further includes a second seal 3. The second seal 3 is sleeved outside the pipe body 16. As Figure 6As shown, when the pipe body 16 in the liquid adding device extends into the workbench of the laundry treating device, the second seal 3 can seal the gap between the pipe body 16 and the laundry treating device, effectively reducing the risk of liquid flowing out between the pipe body 16 and the laundry treating device.

[0087] In some other embodiments, as Figure 7 shown, the structure of the switch assembly 2 is basically the same as that of the above embodiment, except that the top wall 211 of the fixing member is a member provided with a through hole, and the elastic member 22 is sleeved outside the first supporting portion 2321. Then, when the liquid adding device is not installed on the installation table, the first supporting portion 2321 is located between the top wall 211 of the fixing member 21 and the shielding portion 231, and the elastic member 22 presses against the shielding portion 231 to close the liquid outlet 12; when the liquid adding device is installed on the installation table, the top column 5 pushes the second supporting portion 2322 to move upward, and at the same time, the elastic member 22 is compressed. During this process, the first supporting portion 2321 moves upward through the fixing member 21. In this embodiment, since the elastic member 22 is sleeved outside the first supporting portion 2321 in each state, the first supporting portion 2321 plays a limiting role on the elastic member 22, improving the stability of the elastic member 22 moving in the first direction.

[0088] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
