[0029] like Figure 1As shown, the washing machine 100 comprises a housing 1. The housing 1 is provided with a door 2, which is connected to a tub 3 in the housing 1 after opening. Clothes are washed in the tub 3. A feeding box 10 is provided in the housing 1, and a treatment agent is fed into the tub 3 during the washing process. At least a part of the feeding box 10 can be moved relative to the housing 1, so as to allow a user to add a treatment agent thereto.

[0030] Figure 2 A portion of a feeding box 10 for a washing machine 100 is shown. The feeding box 10 comprises an outer box 4 and an inner box 5. The outer box 4 is fixed relative to the housing 1 and comprises a pipe 40 communicating with the tub 3 to deliver a treatment agent mixed with water to the tub 3. The inner box 5 is movably located in the outer box 4, for example, it can be pulled relative to the outer box 4. The inner box 5 is detached from the outer box 4, or moved to be at least partially exposed outside the housing 1, so that the user can add a treatment agent for user clothing treatment, such as detergent, softener, bleach, bactericide, etc., into the inner box 5.

[0031] The inner box 5 includes a storage chamber 51 for accommodating a fluid treatment agent for multiple washes. The washing machine 100 can automatically absorb a corresponding amount of treatment agent from the storage chamber 51 according to the needs of the washing program. The number of storage chambers 51 can be one or more. The inner box 5 can also additionally include a delivery chamber 52 for manually adding a treatment agent for a single wash.

[0032] In order to realize automatic dispensing, the washing machine 100 comprises a liquid extraction device 6 for extracting the treatment agent from the storage chamber 51. The liquid extraction device 6 can be various electric pumps, a venturi structure, or other forms of negative pressure suction devices.

[0033] In order to achieve fluid communication with the pumping device 6, disconnect the pumping device 6 when the inner box 5 moves, and prevent the treatment agent from flowing out of the connection, a connecting valve 7 is provided on the wall 510 of the storage chamber 51.

[0034] like Figures 2 to 5 As shown, the connecting valve 7 includes a first connecting portion 71, which is integrally injection molded with the wall 510 of the storage chamber 51. The outer box 4 is provided with a second connecting portion 41, which can establish a detachable connection with the first connecting portion 71. The second connecting portion 41 is fixedly connected to the outer box 4, or integrally molded. The second connecting portion 41 is also directly or indirectly connected to the liquid pumping device 6, so as to be fluidically connected.

[0035] The first connection part 71 and the second connection part 41 are sealed and connected to each other. The specific connection method can be any known method, such as mutual sleeve connection. The first connection part 71 and the second connection part 41 can be any one of them extending into the other. Figure 4 and Figure 5In the illustrated embodiment, the first connection part 71 includes a first tube 710, and the second connection part 41 includes a second tube 410 slidably inserted into the first tube 710, and the outer side of the second tube 410 is sealed with the inner side of the first tube 710. The seal is usually in the form of an elastic sealing ring.

[0036] In the moving direction of the inner box 5, the first connecting part 71 and the second connecting part 41 are positioned opposite to each other, so when the inner box 5 moves to the working position in the outer box 4, the first connecting part 71 and the second connecting part 41 are connected to each other, and when the inner box 5 is pulled out of the working position, the first connecting part 71 and the second connecting part 41 are disconnected.

[0037] The first connecting portion 71 includes a liquid outlet 711. In the embodiment shown in the drawings, the liquid outlet 711 is located on the first tube 710.

[0038] The connecting valve 7 includes a sealing portion 72, which can move between a first position and a second position, and is elastically biased to the first position, wherein in the first position, the sealing portion 72 blocks the liquid outlet 711, and in the second position, the sealing portion 72 opens the liquid outlet 711. In the embodiment shown in the accompanying drawings, the sealing portion 72 includes a moving part 721 made of a hard material and a sealing part 722 made of an elastic material, and the two are fixed to each other. In some alternative embodiments, the sealing portion 72 can also be made of an elastic material as a whole. The spring 723 is biased to the sealing portion 72, so that the sealing portion 72 tends to the first position. In the first position, the sealing part 722 is squeezed on the edge of the liquid outlet 711, and the moving part 721 closes the liquid outlet 711.

[0039] The second connecting portion 41 includes a pushing portion 411. When the inner box 5 is located at the working position in the outer box 4, the pushing portion 411 pushes the sealing portion 72 to overcome the elastic bias and move to the second position, in which the sealing portion 72 leaves the liquid outlet 711, so that the liquid outlet 711 is in fluid communication with the liquid pumping device 6, so that the liquid pumping device 6 can extract the treatment agent from the storage chamber 51.

[0040] In the embodiment shown in the drawings, the push portion 411 is integrally formed at the front end of the second tube 410. The second tube 410 includes an inlet 412 near the push portion 411, so that after the sealing portion 72 is pushed away from the liquid outlet 711 by the push portion 411, the treatment agent from the storage chamber 51 is allowed to enter the second tube 410 from the inlet 412 and then enter the liquid pumping device 6.

[0041] Therefore, when the inner box 5 moves to the working position in the outer box 4, the first connecting part 71 and the second connecting part 41 are connected to each other, especially the second tube 410 extends into the first tube 710 and moves to make the pushing part 411 push the sealing part 72 away from the liquid outlet 711, and the second tube 410 is fluidically connected with the storage chamber 51 through the inlet 412.

[0042] The connecting valve 7 also includes a straw portion 73. The straw portion 73 is independently formed by injection molding and is installed on the wall 510 from the inside of the storage chamber 51. The treatment agent passes through the straw portion 73 and then enters the liquid extraction device 6 from the first connection portion 71 and the second connection portion 41. The sealing portion 72 is installed inside the straw portion 73, and when the sealing portion 72 is located at the second position, the inside of the straw portion 73 is fluidically connected to the liquid outlet 711. It can be seen that compared with the straw portion 73 being integrally formed on the wall 510 of the storage chamber 51, the independently formed straw portion 73 not only makes the structure of the connecting valve 7 easier to realize in terms of molding process, but also makes the installation of the sealing portion 72 easier, thereby improving production efficiency and saving production costs.

[0043] The straw portion 73 includes a first extension portion 731 extending mainly in the height direction and a second extension portion 732 at an angle to the first extension portion 73. When the inner box 5 slides approximately horizontally relative to the outer box 4, the second extension portion 732 is generally approximately parallel to the sliding direction of the inner box and is therefore approximately horizontal.

[0044] The first extension part 731 includes a suction end 733 near the bottom of the storage chamber 51, so that the treatment agent can be sucked even when the liquid level in the storage chamber 51 is low. The first extension part 731 extends in the height direction to facilitate connection with the connection valve 7 body at a higher position.

[0045] The second extension portion 732 includes a connection end 734 connected to the first connection portion 71 and a support end 735 linearly opposite to the connection end 734. One end of the compressed spring 723 described above is disposed at the support end 735, and the other end is disposed at the moving member 721 of the sealing portion 72.

[0046] The connecting end 734 is disposed around the outer side of the liquid outlet 711 , so that the suction tube portion 73 places both the sealing portion 72 and the liquid outlet 711 within the flow path defined thereby.

[0047] The connection between the connection end 734 and the first connection part 71 can be implemented as follows: the first connection part 71 includes a connection wall 712 protruding toward the inside of the storage cavity 51 or recessed away from the storage cavity 51 , and the connection end 734 of the straw part 73 is sealedly connected to the connection wall 712 .

[0048] Figure 4 and Figure 5 In the illustrated embodiment, a groove 713 is formed on the periphery of the first tube 710 of the first connecting portion 71, and the connecting end 734 extends into the groove 713 and is sealedly connected to the groove 713. In this embodiment, the first tube 710 constitutes the connecting wall 712 mentioned above, or the wall on the other side of the groove 713 opposite to the first tube 710 constitutes the connecting wall 712.

[0049] The connection end 734 and the connection wall 712 may be connected by, for example, a threaded rotation connection, a sliding insertion connection, or a snap connection.

[0050] Figure 4 and Figure 5 In the illustrated embodiment, the connection end 734 is connected to the connection wall 712 by sliding and plugging, which has the advantages of convenient installation and ensuring that the extension direction of the first extension portion 731 after installation is toward the bottom of the storage cavity 51 .

[0051] In order to fix the straw portion 73 and ensure reliable sliding connection, the straw portion 73 has an elastic arm 736 on the outside, a hook 737 on the elastic arm 736, and a stopper 511 extending inwards is provided on the wall 510 of the storage cavity 51. During installation, when the connecting end 734 of the straw portion 73 is slidably connected to the connecting wall 712, the hook 737 on the elastic arm 736 is connected to the stopper 511, so that the stopper 511 prevents the straw portion 73 from being separated from the connecting wall 712.

[0052] pass Figure 4 and Figure 5 With the structural mode of the embodiment shown, the installation of the connecting valve 7 is very easy to achieve: since the first connecting portion 71 is formed on the wall 510 of the storage chamber 51, no installation is required, and it is only necessary to pre-install the spring 723 and the sealing portion 72 on the straw portion 73, and then connect the connecting end 734 of the straw portion 73 with the connecting wall 712, and push the straw portion 73 to slide toward the connecting position. During this process, the hook 737 on the elastic arm 736 is inserted into the limiting portion 511 to complete the installation.

[0053] The various specific embodiments described above and shown in the drawings are only used to illustrate the present invention, and are not the entire present invention. Within the scope of the basic technical concept of the present invention, any form of changes made by ordinary technicians in the relevant technical field to the present invention are within the protection scope of the present invention.
