The washing appliance 1000 has a washing chamber 201 that is open at the top when dishes are loaded. In the example of fig. 1, the washing appliance 1000 is a drawer type washing appliance. It is understood that in other embodiments, the washing appliance 1000 can be a sink-type washing appliance, an embedded washing appliance, a stand-alone washing appliance, or other washing appliances. The following description will be made in detail with an example in which the washing appliance 1000 is a drawer type washing appliance.

The washing appliance 1000 according to the embodiment of the present invention includes a cavity 200 and a dispenser 100, the cavity 200 is formed with a washing chamber 201, and the dispenser 100 is mounted on an inner wall 2011 of the cavity 200.

Specifically, in the present embodiment, the washing appliance 1000 may be a washing appliance 1000 such as a dishwasher (e.g., a drawer dishwasher and a sink dishwasher) and a washing machine (e.g., a drawer washing machine and a sink washing machine). In addition, referring to fig. 1, the washing appliance 1000 generally further includes a housing 300, and the cavity 200 may be located in the housing 300 and can be drawn out and received with respect to the housing 300. The housing 300 may be made of a metal material, for example, a light aluminum material, so that the housing 300 has a light weight. Meanwhile, the cavity 200 may be made of a metal material or a heat-resistant plastic material as long as the strength and heat resistance thereof can be ensured.

In the embodiment of the present invention, the washing appliance 1000 is taken as a drawer type dishwasher for illustration, in the embodiment shown in fig. 1, the washing appliance 1000 is a drawer type dishwasher, the cavity 200 can be connected with the housing 300 through a guide rail (not shown), the cavity 200 can be slidably connected with respect to the housing 300 to slide the cavity 200 out of or into the housing 300 to open or close the washing chamber 201, so that the cavity 200 can be loaded with dishes to enable the drawer type dishwasher to wash the dishes (arrow a in fig. 1 indicates the sliding direction of the cavity 200), and the top of the washing chamber is open when the drawer type dishwasher is loaded with the dishes. It is understood that in other embodiments, the washing appliance 1000 can also be a sink dishwasher, the top of the washing chamber of which is open when dishes are loaded.

In the example of fig. 1, the dispenser 100 is mounted on an inner wall 2011, e.g., a front inner wall, perpendicular to the sliding direction of the chamber 200. It is understood that in other embodiments, the dispenser 100 may be mounted on an inner wall parallel to the sliding direction of the cavity 200, such as a left inner wall or a right inner wall, and the specific arrangement is not limited herein.

Referring to fig. 2, 3 and 4, the dispenser 100 includes a main body 10, a cover 20, a first driving device 30, a second driving device 40, a linkage structure 50 and a limiting structure 60. The cover 20 is movably disposed on the body 10.

It should be noted that, the cover 20 is movably disposed on the body 10, which means that the cover 20 is slidably or rotatably disposed on the body 10, or slidably and rotatably disposed on the body 10. In this context, the cover 20 is slidably disposed on the body 10 for a detailed explanation. It is understood that in other embodiments, the cover 20 may be rotatably disposed on the body 10, for example, the cover 20 may be configured as an upward-hinged cover. Or a sliding and rotating fit.

The body 10 includes a guide portion 12, a mounting plate 14, a first receiving cavity 111, and a second receiving cavity 112.

The body 10 may be made of a plastic material, and in one example, the body 10 may be made of a PP material (polypropylene). It is understood that the body 10 may be an integrally formed structure or a separately formed structure, and is not limited herein.

The guide portion 12 is used for guiding the cover 20 to slide on the body 10. The guide portion 12 includes a first slide groove 121, a second slide groove 122, a first protrusion (not shown), and a second protrusion 123.

The first chute 121 opens on the mounting plate 14. The second sliding slot 122 is opened on the first receiving cavity 111 and the second receiving cavity 112. The first sliding groove 121 and the second sliding groove 122 are both opened along the sliding direction of the cover body 20. The vertical plane of the extending direction of the second sliding groove 121 is different from the vertical plane of the extending direction of the second sliding groove 122, so that the freedom degree of the cover body 20 in multiple directions can be limited, and the cover body 20 can slide more stably.

The cover 20 in this embodiment is L-shaped, and the cover 20 includes a lateral portion 22, a vertical portion 23, and a convex portion, and the lateral portion 22 is used to open and close the first input port of the first receiving cavity 111. The convex portion is provided on the lateral portion 22. The vertical portion 23 is bent relative to the horizontal portion 22 and located on a side of the first receiving cavity 111 away from the mounting plate 14. The first convex portion is formed on the lateral portion 22, and the second convex portion 123 is formed on the vertical portion 23. The first protrusion is slidably engaged with the first sliding groove 121, and the second protrusion 123 is slidably engaged with the second sliding groove 122, so as to guide the cover 20 to slide on the main body 10.

In the present embodiment, the first housing cavity 111, the second housing cavity 112, the first driving device 30, the second driving device 40, the linking structure 50, and the stopper structure 60 are mounted on the mounting plate 14. In this way, the components of the dispenser 100 may be assembled into a single body, so that the dispenser 100 may be quickly mounted to the washing appliance 1000, which is advantageous in improving assembly efficiency.

Specifically, the first receiving cavity 111 and the second receiving cavity 112 are disposed on the same side of the mounting plate 14, and the first driving device 30, the second driving device 40 and the linkage structure 50 are disposed on the other same side of the mounting plate 14. Thus, the space on both sides of the mounting plate 14 can be fully utilized, the occupied space of the distributor is reduced, and the appearance of the distributor 100 is also attractive.

Specifically, the first receiving cavity 111 and the second receiving cavity 112 are arranged in parallel. Further, in the illustrated embodiment, the first receiving cavity 111 and the second receiving cavity 112 are aligned in the sliding direction of the cover 20 (the arrow B in fig. 3 indicates the sliding direction of the cover).

The first receiving cavity 111 is provided with a first input port 110, a first receiving cavity 1111, a first member 1114 and a first opening (not shown).

The first input port 110 is formed at the top of the first receiving cavity 111. The first receiving cavity 111 can be used for placing washing consumables for washing dishes, and the washing consumables can be in a block shape, a powder shape, a liquid shape or a sheet shape. That is, the user can open the first input port 110 of the first receiving chamber 111 by sliding the cover 20, and then load the washing consumables into the first receiving chamber 111 through the first input port 110.

In this embodiment, the first input port 110 is located at the top of the first receiving cavity 111, which means that the first input port 110 faces upward. Of course, the first input port 110 may also be opened on the side wall of the first receiving cavity 111, and the first input port 110 may be opened on the side wall of the first receiving cavity 111 towards the outside of the side wall or the first input port 110 may be opened on the side wall of the first receiving cavity 110 in an inclined manner.

In the example shown in fig. 1 and 2, the direction of the opening of the top of the washing chamber 201 of the cavity 200 is the same as the direction of the first input port 110 of the first housing cavity 111 of the dispenser 100, both of which are directed upwards.

Referring to fig. 4, the second accommodating cavity 112 is opened with a second input opening (not shown), a second accommodating cavity 1121 and a second opening 1124, the second opening 1124 is communicated with the second accommodating cavity 1121, and a movable second member 1126 is disposed at the second opening 1124.

Reference is made to the foregoing description of first delivery port 110 for an explanation and description of the second delivery port. To avoid redundancy, it is not described herein.

In the example of fig. 3, each of the first receiving cavity 1111 and the second receiving cavity 1121 has a substantially rectangular parallelepiped shape. The first input port 110 and the second input port are both substantially rectangular. It is understood that in other embodiments, the first receiving cavity 1111 and the second receiving cavity 1121 can have other regular or irregular shapes, and the first delivery opening 110 and the second delivery opening can have other regular or irregular shapes.

In particular, the washing process of dishware by drawer dishwashers generally comprises a main wash phase and a rinse phase, wherein the dishware can be washed with washing consumables in the form of pieces or blocks in the main wash phase. In this embodiment, the first receiving chamber 1111 may be used for loading the sheet-shaped or block-shaped washing consumables for the main washing stage, such as the dish washing block. The second receiving cavity 1121 may be used for loading a dish detergent for a rinsing stage. That is, the user may load the first receiving cavity 1111 with the sheet-shaped or block-shaped washing consumables through the first input port 110, and may input the dish brightening agent into the second receiving cavity 1121 through the second input port.

Referring to fig. 5 and 6, the first opening communicates with the first receiving cavity 1111, and the first opening is connected with a movable first member 1114. In this embodiment, the first member 1114 is a bottom cover of the first receiving cavity 111.

The first driving device 30 is connected to the first member 1114 through the linkage 50, and the first driving device 30 is used for driving the linkage 50 to move so as to drive the first member 1114 to move, so that the first member 1114 opens and closes the first opening. In this way, the first opening is opened by the first driving device 30, so that the washing consumables placed in the first receiving cavity 1111 can fall through the first opening and enter the washing chamber 201 to participate in the washing of the dishes. Specifically, the first driving device 30 may be controlled by weak current. This is advantageous for improving the safety of the dispenser 100.

Referring again to FIG. 4, the second driving device 40 is used to drive the second member 1126 to move, so that the second member 1126 opens and closes the second opening 1124. In this way, the second opening 1124 is opened by the second driving device 40, so that the washing consumables placed in the second receiving cavity 1121 can fall through the second opening 1124, thereby entering the washing chamber 201 to participate in washing the dishes.

Specifically, the second part 1126 may be a sealing plug and the second opening 1124 may be an opening of a through hole. The second driving means 40 is used to drive the second part 1126 to move, thereby sliding the second part 1126 in and out of the second opening 1124, thereby achieving closing and opening of the second opening 1124. Further, the second member 1126 may be made of rubber.

Of course, in other embodiments, the second driving device 40 can also drive the linkage structure of the second driving device 40 to move the second member 1126, so that the second member 1126 opens and closes the second opening 1124.

It can be understood that the first and second driving devices 30 and 40 respectively control the opening and closing of the first and second openings 1124, so that the washing consumables in the first and second receiving cavities 1111 and 1121 can be independently dispensed, thereby ensuring the cleaning effect of the washing appliance.

In one example, a dish washing block is disposed in the first receiving cavity 1111, a dish washing block is disposed in the second receiving cavity 1121, the first opening is controlled to be opened by the first driving device 30, and the second opening 1124 is controlled to be opened by the second driving device 40, so that the dish washing block is firstly put in, and then the dish brightening agent is put in, so that the dish washing block and the dish brightening agent are put in sequentially.

In the present embodiment, the first driving device 30 and the second driving device 40 may each include a solenoid valve. The solenoid valve has the advantages of low cost, wide application and easy acquisition. The use of the solenoid valves as the power sources of the first and second driving devices 30 and 40 can reduce the cost of the dispenser 100 and improve the production efficiency.

It is understood that in other embodiments, the first driving device 30 and the second driving device 40 may also include a motor, the first driving device 30 may include a motor and the second driving device 40 may include a solenoid valve, and the first driving device 30 may include a solenoid valve and the second driving device 40 may include a motor. The specific form of the first and second driving devices 30 and 40 is not limited herein.

Referring also to fig. 5, the linkage structure 50 includes a first link 52 and a second link 54. The first connecting member 52 is connected to the first driving device 30, the second connecting member 54 is rotatably connected to the first connecting member 52 and the first member 1114, and the first driving device 30 is configured to drive the first connecting member 52 to move so as to drive the second connecting member 54 to move, thereby driving the first member 1114 to move.

Thus, the first driving device 30 can drive the first member 1114 to move simply and conveniently through the linkage structure 50. Specifically, in the present embodiment, the first driving device 30 is used for driving the first connecting element 52 to rotate, so as to drive the second connecting element 54 to move, and thus drive the first part 1114 to rotate. Thus, the first member 1114 can be rotated to open and close the first opening by the first driving device 30. Further, the rotational axis of the first link 52 is non-parallel to the rotational axis of the first member 1114. Referring also to fig. 1, in the illustrated example, the rotation axis of the first connector 52 extends along the sliding direction of the cavity 200, i.e., the direction a. The rotation axis of the first member 1114 extends in the sliding direction of the cover 20, i.e., the B direction. Thus, the rotation of the first link 52 does not cause an increase in the thickness of the dispenser 100, which is advantageous for miniaturization of the dispenser 100.

Of course, the first driving device 30 can also be used to drive the first connecting member 52 to move, so as to drive the second connecting member 54 to move, and thus drive the first member 1114 to slide. Thus, the first member 1114 can slide to open and close the first opening by the driving of the first driving device 30. The specific manner in which the first member 1114 opens and closes the first opening is not limited herein.

In this embodiment, the first member 1114 is a bottom cover of the first receiving cavity 111. First member 1114 includes a bottom cover hinge 1115 and a bottom cover plate 1116. Bottom cover hinge 1115 is fixedly connected to bottom cover plate 1116. The bottom cover hinge 1115 and the bottom cover plate 1116 may be integrated or separated. Second connector 54 is rotatably coupled to bottom cover pivot 1115.

In the present embodiment, one end of the first connecting element 52 is provided with a fitting portion 521, the first driving device 30 includes a driving element 31 and a push rod 32 connected to the driving element 31, and the driving element 31 is configured to drive the push rod 32 to move to drive the first connecting element 52 to move under the condition that at least part of the push rod 32 is fitted in the fitting portion 521.

In this way, the first link 52 and the first driving device 30 are connected by the engaging portion 521 and the push rod 32, so that the first driving device 30 drives the first link 52 to move. Specifically, the housing 312 of the driving member 31 is formed with a through hole 314, and the driving member 31 can drive the push rod 32 to be pushed out of or retracted into the through hole 314.

Further, the push rod 32 includes a connecting portion 324 and a limiting portion 326, the limiting portion 326 is disposed at an end of the push rod 32 away from the driving member 31, the engaging portion 521 surrounds the connecting portion 324, and the limiting portion 326 abuts against one side of the engaging portion 521, so that the push rod 32 is connected to the first connecting member 52. In this way, the first connecting member 52 and the first driving device 30 are prevented from being disengaged by the limiting portion 326.

The push rod 32 may further include a fitting portion 322, the fitting portion 322 is disposed at one end of the connecting portion 324 facing away from the limiting portion 326, and the fitting portion 322 abuts against the other side of the engaging portion 521. The engaging portion 322 engages with the limiting portion 326 to further limit the moving range of the first connecting element 52.

Therefore, the first connecting member 52 moves between the position limited by the matching portion 322 and the position limited portion 326, which not only prevents the linkage from being inaccurate due to the overlarge moving range of the first connecting member 52, but also provides a space for the movement of the first connecting member 52. It is understood that in other examples, the mating portion 322 may be omitted.

In the example of fig. 4 and 5, the connecting portion 324 has a size smaller than that of the stopper portion 326. Specifically, the cross-sectional area of the connecting portion 324 is smaller than the cross-sectional area of the stopper portion 326.

In addition, in the illustrated example, the fitting recess 5212 includes a fitting opening. During assembly, the push rod 32 can be snapped into the engagement portion 521 through the engagement opening, so that the first connecting member 52 and the first driving device 30 are connected.

Of course, the fitting recess 5212 may also include a fitting hole. During the assembly process, the connecting portion 324 of the push rod 32 can extend into the fitting portion 521 through the fitting hole, and after the connecting portion 324 extends into the fitting portion 521, the limiting portion 326 can be fixed to a side of the connecting portion 324 far away from the fitting portion 322, so that the first connecting member 52 and the first driving device 30 can be connected. Specifically, the limiting portion 326 may be welded, adhered or otherwise secured to a side of the connecting portion 324 away from the mating portion 322.

Further, the fitting hole may be a circular hole, an elliptical hole, a square hole, or a hole of other shape. The specific shape of the fitting hole is not limited herein.

The first connecting member 52 includes a first member 522 and a second member 524, an extending direction of the first member 522 is different from an extending direction of the second member 524, a shaft hole 526 is formed at a joint of the first member 522 and the second member 524, the dispenser 100 includes a rotating shaft (not shown) passing through the shaft hole 526, the first driving device 30 is connected to the first member 522, the second member 524 is connected to the second connecting member 54, and the first driving device 30 is configured to drive the first member 522 to move so as to drive the first connecting member 52 to rotate around the shaft, so that the second member 524 drives the first member 1114 to open and close the first opening.

In this manner, the direction of driving of the first driving device 30 is changed by the first link 52, so that the first member 1114 opens and closes the first opening. As shown in fig. 6, when the first driving device 30 is powered off, the push rod 32 is in a state of being pushed out. With the first drive means 30 energized, the push rod 32 retracts, bringing the first member 522 along the direction in which the push rod 32 retracts. Since the shaft hole 526 is provided with a rotating shaft, the movement of the first member 522 drives the second member 524 to rotate around the shaft hole 526 on a plane parallel to the retracting direction of the push rod 32. Since the second link 54 is rotatably connected to the first link 52 and the first member 1114, respectively, rotation of the second member 524 moves the second link 54, causing the first member 1114 to rotate along the axis 1117 parallel to the direction in which the push rod 32 retracts, thereby opening the first opening.

Note that the extending direction of the first member 522 is different from the extending direction of the second member 524, which means that the extending directions of the first member 522 and the second member 524 are not in the same straight line. For example, the first and second members are elongated, and the longitudinal direction of the first member is not collinear with the longitudinal direction of the second member. Specifically, the angle of the first member 522 to the second member 524 is related to the distance of movement of the pushrod 32. Further, the greater the distance of movement of the push rod 32, the greater the angle of the first member 522 to the second member 524.

The first member 522 and the second member 524 may be an integral structure or a separate structure, and are not limited herein. In the example of fig. 5 and 6, the angle of the first member 522 to the second member 524 is acute. It is understood that in other examples, the angle between the first member 522 and the second member 524 may be an obtuse angle. The specific range of angles of the first member 522 and the second member 524 is not limited herein.

The rotating shaft is convexly arranged on the mounting plate 14. The end of the shaft remote from the mounting plate 14 may be formed with a limit end having a size greater than the size of the shaft hole 526. Thus, the movement of the first connector 52 can be limited between the limiting end and the mounting plate 14, and the first connector 52 is prevented from being separated from the rotating shaft during the rotation, which is beneficial to improving the reliability of the distributor 100.

Referring again to fig. 4, the dispenser 100 includes a limiting structure 60, and in the case that the first driving device 30 drives the first member 1114 to open the first opening, the limiting structure 60 limits the movement of the linkage structure 50, so that the first member 1114 maintains a state of opening the first opening. In the present embodiment, when the first driving device 30 drives the first member 1114 to open the first opening, the limiting structure 60 limits the movement of the first connecting member 52 so that the first member 1114 maintains a state of opening the first opening.

In this way, when the first driving device 30 drives the first member 1114 to open the first opening, the movement of the linkage structure 50 is limited by the limiting structure 60, so that even if the first driving device 30 is powered off, the first member 1114 can be kept in a state of opening the first opening, and the washing consumables accommodated in the first accommodating cavity 1111 can enter the washing cavity 201 of the washing appliance 1000 for a sufficient time, thereby ensuring the cleaning effect.

It can be understood that when the washing consumables in the first receiving cavity 1111 are in a sheet, powder or block shape, the washing consumables may be attached to the inner wall of the first receiving cavity 111, and even if the first member 1114 opens the first opening, the washing consumables may not be completely dropped into the washing chamber 201 in a short time. Therefore, it is necessary to maintain the first member 1114 in a state of opening the first opening so that the washing consumables are completely dropped.

Since the first member 1114 opens the first opening in this embodiment by being driven by the first driving means 30, once the first driving means 30 is de-energized and the push rod 32 is ejected, the first member 1114 closes the first opening. The limiting structure 60 limits the movement of the first connecting part 52, so that the first member 1114 keeps the state of opening the first opening, and the first driving device 30 does not need to be powered on to keep the first member 1114 in the state of opening the first opening, which is beneficial to saving energy consumption.

In the case that the first member 1114 maintains the state of opening the first opening, the washing consumables in the first receiving chamber 1111 may be washed down by the liner circulation water of the washing appliance 1000 or sufficiently dissolved in the liner circulation water.

Of course, the washing appliance 1000 may also include a flushing device (not shown) for flushing the first receiving cavity 1111 when the first member 1114 is kept in the state of opening the first opening, so as to flush the washing consumables in the first receiving cavity 1111 into the washing chamber 201 by the water flow.

In the present embodiment, the limiting structure 60 is disposed on a side of the mounting plate 14 away from the first receiving cavity 111. In other words, the first and second receiving cavities 111 and 112 are disposed at one side of the mounting plate 14, and the first driving device 30, the linkage structure 50 and the limiting structure 60 are disposed at the other side of the mounting plate 14. In this way, the space on both sides of the mounting plate 14 can be fully utilized, so that the first receiving cavity 111 and the second receiving cavity 112 are as large as possible, thereby accommodating more washing consumables.

Referring to fig. 5, 7 and 8, the position-limiting structure 60 includes an elastic element 61, a first position-limiting element 62 and a second position-limiting element 64.

The elastic member 61 is used for applying an elastic force to the first limiting member 62 to keep the first limiting member in a state of being biased toward the first driving device 30.

Thus, the elastic member 61 can cooperate with the first limiting member 62, so that the second limiting member 64 moves relative to the first limiting member 62 under the driving of the first driving device 30. Specifically, the elastic member 61 is connected to the first limiting member 62, and an end of the elastic member 61 away from the first limiting member 62 is connected to the mounting plate 14. In the illustrated example, one end of the elastic member 61 is fixed to the mounting plate 14, and the other end is fixedly connected to the first stopper 62.

Further, the elastic member 61 includes a spring, or other elastic elements.

In addition, the elastic member 61 and the first limiting member 62 can be connected by bonding, clipping, screwing or other methods. The specific connection manner between the elastic member 61 and the first limiting member 62 is not limited herein.

Referring to fig. 7 and 8, the first limiting member 62 has a first position and a second position for limiting the movement of the linkage structure 50. The first limiting member 62 further includes a first guiding groove 626, a second guiding groove 628 and a protrusion 629.

The first and second guide grooves 626 and 628 surround the protrusion 629. One end of the first limiting member 62 is fixed to the mounting plate 14, and the first limiting member 62 is movable relative to the mounting plate 14 under the action of the second limiting member 64 and the elastic member 61. In the example of fig. 8, the first stopper 62 is offset to the left and right with respect to the mounting plate 14 by the second stopper 64 and the elastic member 61.

The first guide groove 626 and the second guide groove 628 communicate, the first guide groove 626 forming a first path, the second guide groove 628 forming a second path, the first path and the second path communicating to form a loop. Specifically, the first path refers to a path from the first position 622 to the second position 624 along the first guide groove 626. The second path refers to a path from the second position 624 to the first position 622 along the second guide groove 628.

The first guiding groove 626 is used for guiding the second limiting member 64 to move from the first position 622 to the second position 624. The second guiding slot 628 is used for guiding the second limiting member 64 to move from the second position 624 to the first position 622. In this way, the first guide groove 626 and the second guide groove 628 guide the movement locus of the second limiting member 64, so that the second limiting member 64 can move according to a predetermined locus. In addition, the first location 622 is located on a groove wall of the first guide groove 626 and/or the second guide groove 628.

The protrusion 629 includes a first portion 6291 and a second portion 6292, the first and second portions 6291 and 6292 extend in different directions, the second position 624 is located inside the junction of the first and second portions 6291 and 6292, and the first position 622 is located below the second position 624. In the illustrated example, projections 629 are substantially Y-shaped.

In this way, when the second limiting member 64 moves to the second position 624, even if the first driving device 30 is powered off, the second limiting member 64 is fixed at the second position 624 by the first portion 6291 and the second portion 6292, so that the first member 1114 maintains a state of opening the first opening.

The second limiting member 64 is engaged with the first limiting member 62, and the second limiting member 64 is disposed on the linkage structure 50. In the illustrated example, the second retaining member 64 is disposed at the intersection of the first link 52 and the second link 54. Thus, the second limiting member 64 can be quickly positioned, which is beneficial to improving the assembly efficiency and the production efficiency.

Specifically, the second position-limiting member 64 may have a cylindrical shape. The width of the second retaining member 64 is smaller than the width of the first guide groove 626 and the width of the second guide groove 628. Thus, the second limiting member can slide through the first guiding groove 626 and the second guiding groove 628.

In the present embodiment, the second stopper 64 protrudes from the first connector 52 in a direction toward the first stopper 62. Specifically, the second retaining member 64 is disposed on the second member 524 of the first connecting member 52. It is understood that in other embodiments, the second limiting member 64 can be disposed at other positions of the first member 522 of the first connecting member 52 or the linkage structure 50.

Further, referring to fig. 5, in the present embodiment, a central axis of the second position-limiting member 64 coincides with an axis of the second connecting member 54 rotating relative to the first connecting member 52. It is understood that in other embodiments, the central axis of the second retaining member 64 may be offset from the axis of rotation of the second connector 54 relative to the first connector 52.

The specific position of the second limiting member 64 is not limited herein.

The first driving device 30 is used for driving the first connecting element 52 to move, so as to drive the second limiting element 64 to move from the first position 622 of the first limiting element 62 to the second position 624 of the first limiting element 62 through a first path under the cooperation of the elastic element 61, so that the first member 1114 maintains a state of opening the first opening.

In this way, the second limiting member 64 is engaged with the first limiting member 62 to limit the movement of the first connecting member 52, so that the first member 1114 maintains a state of opening the first opening. In addition, since the elastic member 61 exerts an elastic force on the first limiting member 62, the first limiting member 62 tends to be biased toward the first driving device 30, so that the second limiting member 64 can slide from the end of the second portion 6292 away from the first portion 6291 into the second position 624.

In addition, the first driving device 30 is used for driving the first connecting element 52 to move, so as to drive the second limiting element 64 to move from the second position 624 to the first position 622 through the second path under the cooperation of the elastic element 61, so that the first member 1114 closes the first opening.

Therefore, the second limiting member 64 can be prevented from being unable to slide out from the second position 624, and the elastic member 61 assists the second limiting member 64 to move from the second position 624 to the first position 622. Specifically, in the example of fig. 8, the elastic member 61 applies an elastic force to the first limiting member 62, so that the second limiting member 64 slides out from the second position 624 to return to the first position 622 along the second guiding groove 628 when rotating clockwise around the rotation axis under the driving of the first driving device 30.

The first driving device 30 can be a solenoid valve, the second limiting member 64 moves from the first position 622 to the second position 624 when the first driving device 30 is actuated for the first time, and the second limiting member 64 moves from the second position 624 to the first position 622 when the first driving device 30 is actuated for the second time. In this way, the second limiting member 64 can be alternately located at the first position 622 and the second position 624 by the action of the solenoid valve.

That is, in the example of fig. 8, the first driving device 30 acts once, and the second limiting member 64 rotates clockwise around the rotation shaft under the driving of the first driving device 30, and slides from the first position 622 to the second position 624 along the first guiding groove 626. Even if the first driving device 30 is powered off, the first member 1114 maintains a state of opening the first opening since the second limiting member 64 is limited to the second position 624 by the first portion 6291 and the second portion 6292.

Thereafter, the first driving device 30 is actuated again, and the second limiting member 64 is driven by the first driving device 30 to rotate clockwise from the second position 624 to the first position 622 along the second guiding slot 628. The first member 1114 closes the first opening at this time.

In the above process, the elastic element 61 is driven by the first limiting element 62 to move away from the first driving device 30, and then the first limiting element 62 is driven to move toward the first driving device 30, so that the second limiting element 64 slides into the second position 624. Then, the elastic member 61 is driven by the first limiting member 62 to move in a direction away from the first driving device 30, and then the first limiting member 62 is driven to move in a direction toward the first driving device 30, so that the second limiting member 64 slides into the first position 622.

Of course, in other examples, the elastic member 61 may be omitted. In other words, the first driving device 30 is used for driving the linkage structure 50 to move, so as to drive the second limiting member 64 to move from the first position 622 to the second position 624 through the first path under the coordination of the elastic deformation of the first limiting member 61, so that the first member 1114 maintains a state of opening the first opening.

The first driving device 30 is used for driving the linkage structure 50 to move, so as to drive the second limiting member 64 to move from the second position 624 to the first position 622 through the second path under the coordination of the elastic deformation of the first limiting member 62, so that the first member 1114 closes the first opening.

In this way, the elastic force of the first limiting member 62 is utilized to limit the movement of the second limiting member 64, thereby reducing the number of components of the distributor 100, and being beneficial to reducing the cost and improving the assembly efficiency.

Specifically, the first limiting member 62 is driven by the second limiting member 64 to move away from the first driving device 30, and then the first limiting member 62 moves toward the first driving device 30 by its own elastic force, so that the second limiting member 64 slides into the second position 624. Then, the first limiting member 62 is driven by the second limiting member 64 to move in a direction away from the first driving device 30, and then moves in a direction toward the first driving device 30 by using its own elastic force, so that the second limiting member 64 slides into the first position 622.
