The embodiment of the present application provides a laundry treatment device capable of improving liquid adding efficiency. As shown in FIG. 2 , the laundry treatment equipment includes a liquid filling device 1 , a switch assembly 2 and a workbench 6 .

Combining with Figure 2 and Figure 3, the principle of adding liquid to the laundry treatment equipment is explained as follows:

A liquid inlet channel 4 and a mixing chamber 8 are provided inside the workbench 6 of the laundry processing equipment, and the liquid inlet channel 4 and the mixing chamber 8 are connected through a dispensing pump 7 . The direction of the arrow shown in Fig. 2 indicates the direction of liquid flow. When the liquid feeding device 1 is installed on the workbench 6, the liquid feeding device 1 communicates with the liquid inlet channel 4 in the workbench 6, and the top column 5 in the liquid inlet channel 4 can push the switch assembly 2, so that the liquid feeding device The liquid in 1 can flow into the liquid inlet channel 4.

Wherein, the body 10 and the pipe body 16 are connected into one body, and the connection method can be that the pipe body 16 and the body 10 are integrally formed, and the cross-sectional area of the body 10 is much larger than that of the pipe body 16. It can be understood that the pipe body 16 is set as A channel form with a smaller diameter connects the body 10 with a larger diameter.

As shown in Figure 4, the body 10 is provided with a housing chamber 11 and a liquid outlet 12 inside, the housing chamber 11 is used to accommodate liquid, wherein, the housing chamber 11 in the embodiment of the present application can be used to accommodate detergent, softener, disinfectant and other liquids with a cleaning function. The liquid outlet 12 is in communication with the housing chamber 11. It can be understood that the liquid outlet 12 is the opening liquid outlet of the housing chamber 11; the inside of the tube body 16 is provided with a through liquid outlet channel 161, and the liquid outlet channel 161 communicates with the liquid outlet 12; That is: the liquid outlet 12 is the interface between the accommodation chamber 11 and the liquid outlet channel 161 .

As shown in FIG. 4 , the switch assembly 2 is disposed in the liquid filling device 1 , wherein the switch assembly 2 is at least partially disposed in the accommodating chamber 11 . For example, in the embodiment shown in Figure 4, a part of the switch assembly 2 can also be arranged in the accommodation cavity 11, and the other part can be arranged in the liquid outlet channel 161; in some other embodiments, the switch assembly 2 can also be completely arranged in the chamber 11.

Wherein, when the liquid filling device 1 shown in FIG. 4 is not loaded into the workbench 6 of the laundry processing equipment, the switch assembly 2 closes the liquid outlet 12, and the liquid in the accommodating chamber 11 cannot flow into the liquid outlet channel 161. . When the liquid filling device 1 shown in FIG. 3 is installed on the workbench 6 of the laundry processing equipment, the top column 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 The liquid outlet 12 is opened, so that the liquid in the accommodation chamber 11 can flow into the liquid outlet channel 161 , and further flow into the liquid inlet channel 4 of the workbench 6 . Therefore, the liquid adding device maintains a normally closed liquid discharge state when it is not loaded into the workbench, and a normally open liquid discharge state when the liquid feed device is loaded into the workbench.

A clothes processing device according to an embodiment of the present application. The clothes processing device includes a liquid filling device, a switch assembly and a workbench. The liquid adding device includes a body and a pipe body. The liquid outlet channel, the liquid outlet channel is connected with the liquid outlet, the switch assembly is arranged in the liquid feeding device, and the switch assembly and the liquid feeding device are movably connected to open and close the liquid outlet, and the workbench is provided with a liquid inlet channel, A top post is arranged in the liquid inlet channel, and the pipe body can extend into the liquid inlet channel, so that the top post pushes the switch assembly to open the liquid outlet. In the embodiment of the present application, the switch assembly is arranged in the liquid feeding device, so that when the liquid feeding device is installed on the workbench, the top column can push the switch assembly to open the liquid outlet of the liquid feeding device, so that the liquid in the liquid feeding device can pass through The liquid outlet channel of the liquid filling device flows into the liquid inlet channel of the workbench, and the liquid does not pass through the inside of the switch assembly during the flow process, so that the liquid flow rate will not be limited by the size of the switch assembly, which is conducive to improving the liquid feeding efficiency of the liquid filling device .

In some embodiments, as shown in FIG. 4 , the body 10 includes an end cover 101 and a side wall 102, the side wall 102 encloses an accommodating chamber 11 with an open upper end, and the end cover 101 and the side wall 102 is a detachable connection. When the end cap 101 is separated from the side wall 102, the upper end of the accommodating cavity 11 (the upper end shown in FIG. 4 ) is open, and the user can replenish liquid into the accommodating cavity 11 from the open side. When the end cover 101 is connected to the side wall 102 , the end cover 101 closes the accommodating cavity 11 , so that the accommodating cavity 11 is isolated from the outside of the main body 10 . Wherein, the liquid outlet through which the liquid flows out from the accommodating cavity 11 may be provided at the bottom of the body 10 opposite to the end cover 101 .

In the embodiment of the present application, through the detachable connection between the end cover and the side wall, the liquid can be replenished from the upper end of the body 10, and the liquid can be discharged from the lower end of the body.

When the liquid in the accommodating cavity is exhausted, the detergent can be replenished by opening the end cover, so that the body can be recycled for many times, reducing costs, saving energy and protecting the environment.

In some embodiments, as shown in FIG. 5, the switch assembly 2 includes a fixing member 21, wherein, as shown in FIG. The fixing member 21 is fixedly connected to a side of the body 10 close to the receiving chamber 11 , so that the fixing member 21 can remain stationary relative to the receiving chamber 11 .

The outer diameter of the fixing part 21 is larger than that of the liquid outlet channel 161, which facilitates the vertical connection between the fixing part 21 and the body 10, so as to prevent the bottom of the body from becoming an obstacle to liquid circulation and improve the liquid inlet efficiency. Specifically: with reference to Fig. 4, only when the fixing member 21 is larger than the outer diameter of the liquid outlet channel 161, the fixing member and the body can be connected in the vertical direction, and the connection between the fixing member and the body in the vertical direction is limited. It is beneficial that when the switch assembly opens the liquid outlet, the body will not become an obstacle for the liquid to flow from the accommodating cavity to the liquid outlet. If the fixing part 21 is smaller than the outer diameter of the liquid outlet channel 161, the bottom of the body needs to be inclined toward the fixing part, and the inclined body will inevitably become an obstacle for liquid to flow from the accommodating cavity to the liquid outlet. Furthermore, if the fixing member 21 is smaller than the outer diameter of the liquid outlet channel 161, the diameter of the liquid entering the liquid outlet channel from the accommodating cavity will become smaller, and the obstacle of the obliquely arranged body will eventually lead to liquid leakage. Circulation efficiency is greatly reduced. Therefore, in the present application, the fixing member 21 is arranged in the receiving cavity, and the outer diameter of the fixing member is larger than the outer diameter of the liquid outlet channel, which is beneficial to improve the circulation efficiency of the fluid.

As shown in FIG. 6 , the liquid feeding device is installed on the workbench, and the liquid inlet channel 4 is sleeved on the outer wall of the pipe body 16 .

As shown in FIG. 5 , the switch assembly 2 further includes: an elastic member 22 and a movable member 23 . Wherein, the elastic member 22 extends along a first direction (the up-and-down direction shown in FIG. 4 ), and the extending direction indicates the direction of the largest dimension of the outer contour of the elastic member 22, that is, the length direction of the elastic member. The elastic member 22 has two opposite ends in the length direction, wherein one end of the elastic member 22 is connected to the fixed member 21 , and the other end of the elastic member 22 is connected to the movable member 23 . The connection between the elastic member 22 and the fixing member 21 may be a detachable connection such as clamping or threaded connection, or a permanent fixed connection such as welding. The other end of the elastic member 22 is connected with the movable member 23 .

Combining with Fig. 5 and Fig. 6, the working principle of the switch assembly is explained as follows:

As shown in Figure 5, in the state where the liquid feeding device is not installed on the workbench, correspondingly, the pipe body 16 does not extend into the liquid inlet channel of the workbench, and in this state, the elastic member 22 is in a direction to the movable member 23. In the state of downward thrust, the movable member 23 is pressed against the liquid outlet 12 between the accommodation chamber 11 and the liquid outlet channel 161 under the elastic force of the elastic member 22, so that the liquid outlet 12 is closed, and the liquid in the accommodation chamber 11 Can't flow out from liquid outlet 12 places.

As shown in Figure 6, in the process of installing the liquid adding device on the workbench, the liquid adding device is inserted downward into the workbench, and in this process, the movable part 23 moves towards the direction close to the top column 5 until it is in contact with the top column. 5 butt. Since the movable part 23 abuts against the top column 5, the movable part 23 is pushed upward by the upward thrust of the top column 5 to push the movable part 23 to move upward in a direction away from the liquid outlet 12. At the same time, the movable part 23 continuously compresses the elastic during the upward movement. piece 22. 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 (the state shown in FIG. 5 ) to the state in which the movable member 23 opens the liquid outlet 12 (the state shown in FIG. 6 ). , the gap between the movable member 23 and the liquid outlet 12 gradually increases to a maximum value. In the state where the liquid outlet 12 is open, the liquid in the housing 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 speed of the liquid flowing into the liquid inlet channel 4 depends on the The diameters of the liquid outlet 12 and the liquid outlet channel 161 are determined and not limited by the internal size of the switch assembly, so that the liquid filling efficiency of the liquid filling device can be improved.

As shown in Figure 5, in the process of taking out the liquid-filling device from the workbench, the liquid-fill device breaks away from the workbench, and the movable part 23 moves away from the direction of the top column 5 (the upward direction shown in Figure 6). 23 is out of contact with the top post 5, the movable part 23 is not subjected to the upward thrust applied by the top post 5, and the elastic part 22 exerts a downward force on the movable part 23, so that the movable part 23 returns to the position of closing the liquid outlet 12. state.

In some embodiments, as shown in FIG. 5 , the movable member 23 includes a shielding portion 231 and a supporting portion 232 . The blocking portion 231 abuts against one end (the lower end shown in FIG. 5 ) of the elastic member 22 . The shielding portion 231 extends along a second direction (a left-right direction shown in FIG. 5 ), and the second direction is perpendicular to the first direction. When the liquid filling device is disengaged from the workbench, the blocking part 231 is not pushed by the push column 5 , and under the action of the elastic force of the elastic member 22 , the blocking part 231 abuts against the body 10 to close the liquid outlet 12 .

As shown in Figure 6, when the liquid filling device is installed on the workbench, the blocking part 231 is pushed by the push column 5, and the blocking part 231 moves upward away from the liquid outlet 12, and compresses the elastic member 22, thereby opening the liquid outlet. port 12; the liquid in the housing cavity 11 flows from the gap between the shielding part 231 and the liquid outlet 12 to the liquid outlet 12, then flows to the liquid outlet channel 161, and flows from the liquid outlet channel 161 to the inlet of the workbench. in liquid channel 4.

As shown in Figure 5, the support part 232 is connected with the shielding part 231 and extends along the first direction, the support part 232 can be a rod-shaped structure, it can be understood that the length direction of the support part 232 is defined as the first direction (shown in Figure 5 shows the up-down direction), and the support portion 232 is at least partially disposed in the liquid outlet channel 161 . In the process of installing the liquid filling device on the workbench, compared with the shielding part 231, the top column 5 can first contact the support part 232, and the support part 232 can be pushed by the top column 5 in the first direction (the up and down direction shown in Figure 5 ) movement, so that the supporting part 232 drives the shielding part 231 to move away from the liquid outlet 12, so that the shielding part 231 opens the liquid outlet 12; The thrust of the column 5 gradually decreases, and the elastic member 22 can recover its deformation under the elastic force, and the elastic force can push the shielding part 231 and the supporting part 232 to move towards the direction close to the liquid outlet 12 until the supporting part 232 is completely in contact with the liquid outlet. The push post 5 is out of contact, and the shielding portion 231 recovers to the position of shielding the liquid outlet 12 under the elastic force.

In the embodiment of the present application, a support portion extending along the first direction is provided on the shielding portion, so that the switch assembly is arranged in a T-shaped structure. On the one hand, the elastic member can be conveniently wound around the support portion; on the other hand, the support portion can also be provided The cross-sectional area of the cylinder matches the cross-sectional area of the top column in the liquid inlet channel, so that the top column can easily touch the switch assembly, reduce the difficulty of switching between the two working states of the switch assembly, and improve the smoothness of the liquid filling device.

In some embodiments, as shown in FIG. 5 , the ratio of the outer diameter M1 of the support portion 232 in the second direction (left-right direction shown in FIG. 5 ) to the diameter M2 of the liquid outlet 12 is less than or equal to 0.3. The area of the shielding part 231 in the second direction is larger than the area of the liquid outlet 12. When the liquid filling device is separated from the workbench, the shielding part 231 can close the liquid outlet 12, so that the liquid in the accommodation chamber 11 cannot pass through the liquid outlet. 12 flows to the outlet channel 161.

In the embodiment of the present application, by limiting the ratio of the radial dimension of the support part to the liquid outlet within a certain range, the support part can not only realize 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 export efficiency of the liquid outlet.
