Description

Technical Field

[0001] This invention relates to the field of detergent dispensing technology, and more specifically, to a dispenser and a dishwasher. Background Technology

[0002] Dispensers are increasingly being used in washing equipment to distribute detergent to the washing area within a specified time to complete the subsequent washing process.

[0003] Dispensers are widely used dispensers. In related technologies, detergent in the dispenser forms a small gap at the junction of the chambers, which can easily lead to capillary action, resulting in a small amount of detergent spilling out. However, the structure of existing dispensers needs improvement. Summary of the Invention

[0004] Therefore, the present invention proposes a dispenser that can prevent capillary action during dispenser use.

[0005] The dispenser according to an embodiment of the present invention includes:

[0006] A first housing, the first housing including a first cavity and a second cavity, the first cavity being used to hold a first detergent, and the second cavity being used to allow a second detergent to flow out;

[0007] The second housing, combined with the first housing, forms a second detergent receiving cavity. The second detergent receiving cavity includes a pre-storage cavity, a transition cavity, and a dispensing cavity. The dispensing cavity is connected to the second cavity. The driving assembly controls the second detergent to sequentially pass through the pre-storage cavity, the transition cavity, and the dispensing cavity. The wall forming the pre-storage cavity includes a first wall located in the first housing and a wall located in the second housing.

[0008] The first corresponding wall is at least partially connected to the first wall and the first corresponding wall, and a first gap is formed between the first wall and the first corresponding wall. The first gap has a first part and a second part. The first part is close to the connection between the first wall and the first corresponding wall, and the second part is far away from the connection between the first wall and the first corresponding wall relative to the first part. The width of the second part is greater than that of the first part.

[0009] According to an embodiment of the present invention, a first notch is formed between the first wall and the first corresponding wall, and the width of the second part of the first notch is greater than the width of the first part, thereby reducing capillary action caused by small gaps and reducing detergent overflow when the dispenser is used.

[0010] In some embodiments, the first wall includes a first extension wall, and at least a portion of the wall surface of the first extension wall facing the direction of the corresponding wall is inclined.

[0011] In some embodiments, at least a portion of the first extended wall facing the second housing is an inclined surface, the inclined surface gradually sloping inward toward the cavity along the direction close to the pre-storage cavity.

[0012] In some embodiments, at least a portion of the first corresponding wall surface facing the first wall is an inclined surface, the inclined surface gradually sloping inward toward the cavity along a direction close to the cavity of the pre-storage cavity.

[0013] In some embodiments, the first notch is V-shaped, and the bottom of the first notch is the connection point between the first wall and the first corresponding wall.

[0014] In some embodiments, the inclined surface of the second extension wall is inclined along the direction close to the cavity of the pre-storage cavity, and the second housing further includes a second corresponding wall that cooperates with the second extension wall. At least a portion of the wall surface of the second corresponding wall is inclined, and a second notch is formed between the second extension wall and the second corresponding wall. The shape of the second notch is V-shaped, and the opening of the second notch gradually increases along the direction of extension of the cavity of the pre-storage cavity.

[0015] In some embodiments, a first channel is provided on one side of the storage cavity, the first channel being located away from the pre-storage cavity, and a float is provided in the first channel for indicating the amount of second detergent in the storage cavity.

[0016] In some embodiments, a circuit board is provided on the outer wall of the storage cavity, and a magnetic switch is provided on the circuit board. The magnetic switch responds to the float. When the second detergent dosage in the storage cavity is low, the circuit board sends a signal to indicate that a second detergent needs to be added.

Detailed Implementation

[0042] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0043] like Figure 1-20 As shown, the dispenser according to an embodiment of the present invention includes a body 1, a first cover 2 and a drive assembly 3. The body 1 has a first cavity 101 recessed in the vertical direction. The first cavity 101 is used to store a first detergent, wherein the first detergent can be a common detergent (e.g., dishwashing powder) used by a dishwasher when washing dishes.

[0044] The first cover 2 is mounted on the main body 1. The first cover 2 can slide on the main body in the front-to-back direction, and the first cover 2 can change between an open position where the first cavity 101 is opened and a closed position where the first cavity 101 is closed. The lateral direction is perpendicular to the front-to-back direction and the vertical direction. For example, the first cover 2 can slide relative to the main body 1, or the first cover 2 can be flipped relative to the main body 1. In this embodiment, the first cover 2 is slidable relative to the main body 1.

[0045] Specifically, the first cover 2 is located on the body 1. The first cover 2 includes a first holding part 21 and a switching part 22. The first holding part 21 is used to cooperate with the connecting part 31 to allow the first cover 2 to change between an open position and a closed position of the first cavity 101. The first cover 2 moves on the body 1 and has a first position and a second position. The switching part 22 can move from the first position to the second position in a front-back direction. The switching part 22 is located in the direction near the left end face of the first cover 2, and the first holding part 21 is located in the direction near the right end face of the first cover 2. The first end of the first cover 2 cooperates with the body 1, which can realize the opening and closing of the first cavity 101 by the first cover 2. In this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include at least one of that feature.

[0046] Specifically, the free end of the switch part 22 is provided with a first push part 221 and a second push part 222, and the drive assembly 3 includes a connecting part 31, which is connected to one end of the first cover 2 adjacent to the body 1. Figure 2 The rear end of the first cover 2 shown is movably fitted to the first cavity 101. The first pushing part 221 cooperates with the connecting part 31. Specifically, the first holding part 21 is used to cooperate with the connecting part 31 to allow the first cover 2 to change between the open and closed positions of the first cavity 101. It can be understood that, relative to the dispenser, the end adjacent to the interior of the dispenser is the inner end, and the end away from the interior of the dispenser is the outer end. Therefore, the end of the first cover 2 adjacent to the body 1 is the inner end of the first cover 2. It should be noted that, in this invention, the upper end refers to the direction along which the first cavity 101 of the dispenser is opened, and the direction along which the first cavity 101 of the dispenser is closed, and the lower end refers to the direction along which the first cavity 101 of the dispenser is closed. It can be understood that, relative to the dispenser, the end of the first cover 2 adjacent to the interior of the dispenser is the rear end, and the end away from the interior of the dispenser is the front end.

[0047] Specifically, the switch part 22 can move from a first position to a second position in the front-back direction. When the switch part 22 is in the first position, the first holding part 21 is engaged with the connecting part 31, the first pushing part 221 is spaced apart from the connecting part 31, and the first cover 1 closes the first cavity 101. When the switch part 22 moves from the first position to the second position, the first pushing part 221 abuts against the connecting part 31, the first holding part 21 disengages from the connecting part 31, the first cover 1 opens the first cavity 101, and the first cover 2 opens the first cavity 101 for easy operation. When the switch part 22 moves from the first position to the second position, the first cover 2 starts preparing to move from the closed position fixed to the first cavity 101. After the switch part 22 moves from the first position to the second position, the first cover 2 moves from the closed position of the first cavity 101 to the open position, thereby opening the first cavity 101. At the same time as the first cover 2 opens the first cavity 101, the switch part 22 moves from the second position to the first position. It is understood that the connecting part 31 can be part of the driving component 3, or it can be connected to the driving component 3 as a separate component. In the embodiments of the present invention, the connecting part 31 can be part of the driving component 3.

[0048] According to an embodiment of the distributor, the free end of the switch section 22 (e.g.) Figure 2 , 3The first pushing part 221 and the second pushing part 222 (shown at the upper end) are at least partially parallel. The first pushing part 221 engages and disengages with the connecting part 31 of the drive assembly 3, and the second pushing part 222 cooperates with the first cover 2 to coordinate the engagement and disengagement of the first pushing part 221 with the connecting part 31 of the drive assembly 3, thereby improving the structural stability of the switch part 22. Specifically, during the opening of the first cover 2 from front to back, the second pushing part 222 and the first pushing part 221 move from back to front. The first pushing part 221 engages with the connecting part 31, while the second pushing part 222 does not contact the connecting part 31.

[0049] The free start end of the switch section 22 (e.g.) Figure 2 , 3 The lower end (shown) is provided with a movable part 23. The movable part 23 moves along the opening direction of the first cover 2 during the process of the switch part moving from the first position to the second position. In other words, the movable part 23 is provided at the front end of the switch part 22, and the movable part 23 moves simultaneously with the first push part 221 and the second push part 222. An external force can be applied to the movable part 23 of the switch part 22 to drive the first push part 221 of the switch part 22 to operate, that is, the external force can be applied to the switch part 22 from the outside of the distributor.

[0050] In some embodiments, the first actuating portion 221 and the second actuating portion 222 of the switching portion 22 are located at one end of the switching portion 22 (e.g., ...). Figure 2 , 3 The moving part 23 of the switch part 22 is located at the other end of the switch part 22 (as shown in the rear end). Figure 2 , 3 (As shown in the front end), the first pushing part 221 and the second pushing part 222 are connected to each other through the moving part 23. In addition, the first pushing part 221 and the second pushing part 222 can also be integrally formed through the moving part 23.

[0051] Specifically, the first pushing part 221 includes a first flat part 2211 and a first bent part 2212, which are connected. The first bent part 2212 is located at one end of the first pushing part 221. When the first cover 2 is in the first position, the first holding part 21 cooperates with the connecting part 31. When the first cover 2 is in the second position, the first bent part 2212 cooperates with the connecting part 31, and the first holding part 21 disengages from the connecting part 31. The second pushing part 222 includes a second flat part 2221 and a second bent part 2222, which are connected. The second bent part 2222 is located at one end of the second pushing part 222. It can be understood that the first flat part 2211 and the first bent part 2212 can be integrally formed or assembled and fixedly connected. In this embodiment, the first flat part 2211 and the first bent part 2212 are integrally formed. The second flat portion 2221 and the second bent portion 2222 can be integrally formed or assembled and fixedly connected. In this embodiment, the second flat portion 2221 and the second bent portion 2222 are integrally formed.

[0052] The switch section 22 includes an elastic device 224 located between the first pushing section 221, the second pushing section 222, and the moving section 223. This elastic device 224 is used for moving the switch section 22 to a first position and a second position. When the switch section 22 moves from the first position to the second position, the second pushing section 222 moves simultaneously with the first pushing section 221. The first flat section 2211 and the second flat section 2221 are parallel, and the first bending section 2212 and the second bending section 2222 bend in opposite directions. It should be noted that in this embodiment, the left end refers to the direction closer to the first holding section 21, and the right end refers to the direction farther from the first holding section 21. "Parallel" means generally parallel; however, considering errors or other factors in manufacturing processes and actual operation, the degree of parallelism may vary slightly. According to an embodiment of the present invention, the connector 31 includes a planar portion 311 and a protruding portion 312, which are integrally formed. When the first cover 2 is in the first position, the first cover 2 is fixed in the closed position of the first cavity 101, and the protruding portion 312 cooperates with the first holding portion 21. When the first cover 2 is in the second position, the first bending portion 2212 of the first pushing portion 221 cooperates with the planar portion 311, and the first holding portion 21 disengages from the protruding portion 312 of the connector 31.

[0053] According to an embodiment of the present invention, the drive assembly 3 further includes a control valve 4, a rotating shaft 32, a rotating arm 33, and a connecting member 34. The rotating arm 33 is connected to the connecting portion 31 and the rotating shaft 32, and is located between the rotating shaft 32 and the connecting portion 31. The connecting member 34 includes a cylindrical body 341 and an extension portion 342 extending outward from the outer periphery of the cylindrical body 341. The cylindrical body 341 is wound around the second end of the rotating shaft 32 (e.g., ...). Figure 6 As shown at the rear end), the control valve 4 is connected to the extension 342 to drive the main body 1 to rotate via the extension 342, and the cylinder 341 can drive the rotating shaft 32 to rotate. Specifically, as Figure 12 As shown, the control valve 4 has a valve core 42, and an extension 342 at one end away from the cylinder 341 (e.g. Figure 6 The rear end shown contacts one end face of the valve core 42, energizing the control valve 4. The valve core 42 actuates, thereby driving the end of the extension 342 away from the cylinder 341 (e.g., the rear end shown) to contact one end face of the valve core 42. Figure 6 The rear end (as shown) moves, thereby causing the cylinder 341 to rotate, and the rotation of the cylinder 341 can drive the rotating shaft 32 to rotate. It should be noted that the rear end refers to the end away from the first cover 2.

[0054] Specifically, the rotating shaft 32 is rotatably connected to the body 1 to drive the protrusion 312 of the connecting part 31 to disengage from and engage with the first cover 2. It can be understood that when the first cover 2 is in the first position, the first holding part 21 engages with the connecting part 31 to lock the first cover 2 in the closed position. When unlocking is required, the first cover 2 can be unlocked manually or automatically. When unlocking manually, an external force acts on the moving part 23 of the switch part 22, causing the first holding part 21 of the switch part 22 to disengage from the connecting part 31, allowing the first cover 2 to slide from the closed position to the open position. When unlocking automatically, the rotating shaft 32 mounted on the body 1 rotates, and the rotating arm 33 moves with the connecting part 31, driving the protrusion 312 of the connecting part 31 to disengage from the first cover 2, thereby allowing the first cover 2 to slide from the closed position to the open position.

[0055] In some specific embodiments, the connector 34 includes a cylindrical body 341 and an extension 342 extending outward from the outer peripheral surface of the cylindrical body 341. The extension 342 extends from the end face of the rotating arm 33 on the side away from the rotating shaft 32 (e.g., Figure 8 , 9 The front end face of the rotating arm 32 shown is along the direction away from the rotating shaft 32. Figure 8 , 9 Extending in the direction from back to front (as shown), the first end of the rotating shaft 41 ( Figure 8 , 9 The front end of the rotating shaft 32 shown is connected to the rotating arm 33. The rotating shaft 32 is rotatably mounted on the body 1. Driven by the rotating shaft 32, the rotating arm 33 can push the first pushing part 221 of the switch part 22 to move, so that the first holding part 21 of the switch part 22 is disengaged from the body 1. It can be understood that the extension part 342 and the cylinder 341 can be directly connected or integrally formed.

[0056] More specifically, the free end of the switch portion 22 also has a second pushing portion 222, the second pushing portion 222 being directed toward the body 1. Figure 2Extending from bottom to top, and with the second pushing part 222 and the first pushing part 221 spaced apart from each other, as shown in the image. Figure 4 As shown, the first pushing part 221 is located at the left end of the second pushing part 222, and the first pushing part 221 is connected to the second pushing part 222. When the rotating shaft 32 rotates, it can drive the protrusion 312 of the connecting part 31 to push the first pushing part 221 of the switch part 22 to move, thereby causing the first holding part 21 to disengage from the body 1.

[0057] In some embodiments, the dispenser further includes an opening elastic element 5, which is disposed between the body 1 and the first cover 2, and is used to push the first cover 2 toward the open position. It is understood that when the first cover 2 is slidable relative to the body 1, after the first holding part 21 of the switch part 22 disengages from the body 1, the first cover 2 slides from the closed position of closing the first cavity 101 to the open position of opening the first cavity 101 under the action of the opening elastic element 5. Specifically, the opening elastic element 5 is a torsion spring, with a first end connected to the body 1 and a second end connected to the first cover 2. Thus, after the first holding part 21 of the switch part 22 disengages from the body 1, the torsion spring slides the first cover 2 from the closed position of closing the first cavity 101 to the open position of opening the first cavity 101.

[0058] In some embodiments, such as Figure 3 As shown, the main body 1 includes a first housing 11 and a second housing 12. A first cavity 101 is disposed within the first housing 11, and a first cover 2 is slidably mounted on the first housing 11. The second housing 12 is combined with the first housing 11. It can be understood that, in the vertical direction, the first housing 11 is located above the second housing 12. The first cavity 101 and the second cavity 102 are disposed on the upper surface of the first housing 11, and the drive assembly is mounted on the lower surface of the second housing.

[0059] In some specific embodiments, the first latching portion 21 of the switch portion 22 and the first housing 11 can engage to lock the first cover 2 in the closed position, and the first latching portion 21 of the switch portion 22 and the first housing 11 can disengage to allow the first cover 2 to move from the closed position to the open position. Specifically, one end of the first housing 11 adjacent to the first cover 1 ( Figure 2 , 3 The front end of the first housing 11 shown has a protrusion 312, and the first holding part 21 of the switch part 22 and the protrusion 312 of the first housing 11 can be engaged and disengaged.

[0060] In some embodiments, the second housing 12 is combined with the first housing 11 to form a second detergent receiving cavity. The second detergent receiving cavity includes a pre-storage cavity 103, a transition cavity 107, and a dispensing cavity 108. The pre-storage cavity 103 and the storage cavity 104 are disposed within the second housing 12 and are used to store the second detergent. The second detergent is a rinsing agent, such as a rinse aid used in a dishwasher to enhance the washing effect when cleaning dishes, also known as a rinse oil.

[0061] The second cavity 102 is provided in the first housing 11. The wall of the second cavity 102 has a connecting hole 13, which connects the storage cavity 104 and the second cavity 102. The storage cavity 104 and the pre-storage cavity 103 are connected. The second detergent can flow from the storage cavity 104 into the pre-storage cavity 103 so that the second detergent in the pre-storage cavity 103 can enter the second cavity 102 through the connecting hole 13. The second cavity 102 is used for the outflow of the second detergent.

[0062] The second cavity 102 has an addition nozzle 14 on its wall. The addition nozzle 14 extends from the second cavity 102 toward the storage cavity 104 and is funnel-shaped. The addition nozzle 14 has multiple addition holes to add the second detergent into the storage cavity 104, and also facilitates observation of the liquid level of the second detergent in the second cavity 102. To improve manufacturing efficiency, the addition nozzle 14 is an integral injection molded part. Furthermore, the addition nozzle 14 is integrally formed with the body 1, but this application is not limited to this.

[0063] The dispenser also has a second cover 6 for opening and closing the second chamber 102. Specifically, the second cover 6 is flip-mounted on the body 1. It is understood that flipping the second cover 6 allows the second chamber 102 to be opened and closed to facilitate the subsequent addition of a second detergent.

[0064] Understandably, the allocator should first be set to a position such as... Figure 1 In the horizontal position shown, flipping the second cover 6 opens the second cavity 102, and the second detergent is added to the storage cavity 104 from the adding hole of the adding nozzle 14. After the addition is complete, flipping the second cover 6 in the opposite direction closes the second cavity 102, so that the second detergent is stored in the storage cavity 104 and the pre-storage cavity 103. At the same time, when the second detergent in the pre-storage cavity 103 is low, the second detergent flows from the storage cavity 104 into the pre-storage cavity 103. Next, the dispenser is placed in the vertical position, and the second detergent in the pre-storage cavity 103 flows from the pre-storage cavity 103 to the transition cavity 107, then from the transition cavity 107 to the dispensing cavity 108, and then flows into the second cavity 102 from the connecting hole 13. The second detergent in the second cavity 102 flows into household appliances such as dishwashers to provide a second additive for the corresponding household appliances.

[0065] The drive assembly 3 has a sealing component 421, which includes a first sealing portion 4211 and a first sealing portion 4212. The sealing portion 421 has a first state and a second state. In the first state, the first sealing portion 421 seals the first through hole 1071 to disconnect the communication between the pre-storage chamber 103 and the transition chamber 107, and the second sealing portion 4212 seals the second through hole 1081 to disconnect the communication between the transition chamber 107 and the dispensing chamber 108. In the second state, the pre-storage chamber 11 and the first transition chamber 12 are connected through the first through hole 1071, and the second sealing portion 4212 seals the second through hole 1081 to disconnect the communication between the transition chamber 108 and the dispensing chamber 108. The dispensing chamber 108 is connected to the second chamber 102 to allow the second detergent to flow out.

[0066] In some embodiments, the second housing 12 has a pre-storage cavity 103 for pre-storing a second detergent, and the pre-storage cavity 103 is located on one side of the second housing 12 (e.g., Figure 10 As shown above, the wall forming the pre-storage cavity 103 includes a first wall 1031 located on the first housing 11 and a first corresponding wall 1201 located on the second housing 12. The first wall 1031 is located on one side of the pre-storage cavity 103. Figure 10 As shown on the upper side, the first wall 1031 and the first corresponding wall 1031 are at least partially connected, and a first notch 105 is formed between the first wall 1031 and the first corresponding wall 1031. The first notch 105 has a first part 1051 and a second part 1052. The first part 1051 is close to the connection between the first wall 1031 and the first corresponding wall 1031, and the second part 1051 is far away from the connection between the first wall 1031 and the first corresponding wall 1051 relative to the first part 1051. The width of the first part 1051 is smaller than the width of the second part 1052. Because capillary action occurs when the first housing 11 and the second housing 12 are joined, some detergent overflows from the dispenser. The width of the second part 1052 is greater than that of the first part 1051, thus forming a V-shaped groove structure with a smaller lower end and a larger upper end, which can reduce the occurrence of capillary action and thus reduce detergent overflow when the dispenser is used. Specifically, the second housing 12 also has a storage cavity 104, with a pre-storage cavity 103 communicating with the storage cavity 104, and the storage cavity 104 located on one side of the second housing 12 (e.g., Figure 10 (As shown on the lower side), the first wall 1031 includes a first extension wall 1032, which extends in a direction along the cavity of the pre-storage cavity 103 (e.g., the lower side). Figure 10 As shown below, at least a portion of the wall surface of the first extension wall 1032 facing the second housing 12 is inclined; in other words, one end of the first extension wall 1032 (as shown below) is inclined. Figure 10The end face of the front end (shown) is beveled, which can reduce capillary action when the first housing 11 and the second housing 12 are joined, thereby reducing detergent spillage during dispenser use. More specifically, the bevel of the first extension wall 1032 gradually slopes inward toward the cavity near the pre-storage cavity 103. It can be understood that the first extension wall 1032 and the first wall 1031 can be directly connected or integrally injection molded.

[0067] At least a portion of the wall surface of the second housing 12 facing the first housing 11 and cooperating with the first wall 1031 is inclined. A first notch 105 is formed at the point where the second housing 12 and the first wall 1031 of the first housing 11 meet. The first notch 105 is V-shaped. The bottom of the first notch 105 is the connection point between the first wall 1031 and the first corresponding wall 1201. The opening size of the first notch 105 gradually increases along the direction inside the pre-storage cavity 103, which can reduce the capillary phenomenon when the first housing 11 and the second housing 12 are joined, thereby reducing the overflow of detergent when the dispenser is used.

[0068] In some embodiments, the walls forming the pre-storage cavity 103 further include a second wall 1033 and a third wall 1035, with the first wall 1031 and the third wall 1035 connected, and the second wall 1033 and the third wall 1035 connected. The third wall 1035 is located between the first wall 1031 and the second wall 1033, and the second wall 1033 is located on one side of the pre-storage cavity 103 (e.g., Figure 10 The third wall 1035 is located on one side of the pre-storage cavity 103 (as shown above). Figure 10 (As shown on the lower side), the second wall 1033 includes a second extension wall 1034, which extends in a direction along the cavity of the pre-storage cavity 103 and in a direction away from the storage cavity 104. At least a portion of the wall surface of the second extension wall 1034 facing the second housing 12 is inclined. It is understood that the second wall 1033, the third wall 1035, and the first wall 1031 can also be integrally injection molded.

[0069] Specifically, at least a portion of the wall surface of the second extension wall 1034 facing the second housing 12 is inclined, and the inclined surface slopes in the direction close to the cavity of the pre-storage cavity 103. The second housing 12 also includes a second corresponding wall 1202 that mates with the second extension wall 1034. At least a portion of the wall surface of the second corresponding wall 1202 is inclined, and a second notch 106 is formed between the second extension wall 1034 and the second corresponding wall 1202. The second notch 106 is V-shaped, and the opening of the second notch 106 gradually increases in the direction extending into the cavity of the pre-storage cavity 103. This can reduce the capillary effect when the first housing 11 and the second housing 12 are joined, thereby reducing detergent spillage during dispenser use. It is understood that the second extension wall 1034 and the second wall 1033 can be directly connected or integrally injection molded.

[0070] In some embodiments, one side of the storage cavity 104 (e.g.) Figure 10 The lower side shown) is provided with a first channel 1041, which is located on the side away from the pre-storage cavity 103 (e.g., the lower side). Figure 10(As shown below), the first channel 1041 extends along the direction close to the pre-storage cavity 103; in other words, the first channel 1041 extends vertically. A float 1042 is provided within the first channel 1041 to indicate the amount of second detergent in the storage cavity 104. The float 1042 can move vertically but not horizontally. Reinforcing ribs are provided on the left and right sides of the first channel 1041 to prevent the float 1042 from moving horizontally. Specifically, an iron core 1044 is provided within the float 1042. A circuit board 1043 is provided on the outer wall of the storage cavity 104. The circuit board 1043 is connected to an external power supply. A magnetic switch 1045 is provided on the circuit board 1043. The magnetic switch 1045 responds to the float 1042. When the amount of second detergent in the storage cavity 104 is low, the float 1042 moves downward, and the circuit board 1043 sends a signal to indicate that second detergent needs to be added. When the dishwasher is operating, the dispenser is placed vertically. When the amount of second detergent in the storage cavity 104 is low, the float 1042 will sink. The iron core 1044 in the float 1042 can respond to the magnetic switch 1045, thereby connecting the circuit in the circuit board 1043. The circuit board 1043 then sends a signal to the user, prompting them to add second detergent, thus ensuring that the amount of second detergent is sufficient. It can be understood that the iron core 1044 is a magnet, which can generate magnetic force, and the magnetic switch 1045 is a reed switch. Under the action of magnetic force, the two iron elastic springs inside the reed switch can attract and separate. When the magnetic switch 1045 is not in operation, the two reeds inside the reed switch are not in contact. When a magnet approaches the magnetic switch 1045, the two reeds are magnetized and attracted to each other under the influence of the magnetic field, thus connecting the circuit. When the magnetic magnet moves away from the magnetic switch 1045, without the influence of external magnetic force, the two reeds will separate due to their own elasticity, breaking the circuit.

[0071] According to an embodiment of the present invention, the dispenser includes a control valve 4 for controlling the dispensing of a second detergent. The control valve 4 is provided with at least one positioning groove 401, located on one side of the control valve 4 away from the storage cavity 104 (outer side as shown in FIG. 10), and on one side of the second housing 12 (as shown in FIG. 10). Figure 10The outer side (as shown) is provided with at least one positioning platform 120, which cooperates with the positioning groove 401, thereby ensuring a tight fit between the control valve 4 and the second housing 12. The control valve 4 will not move from the second housing 12, improving the reliability of the control valve 4's structural fixation. The positioning platform 120 is an elastic structure. When the positioning platform 120 is housed in the positioning groove 401, the drive assembly 3 is fixed to the second housing 12. When the positioning platform 120 is driven by an external force to disengage from the positioning groove 401, the drive assembly 3 can be disassembled from the second housing 12. In other words, the drive assembly 3 can be released from the second housing 12. It should be noted that the outer side of the second housing 12 refers to the direction away from the pre-storage cavity 103 or the storage cavity 104, and the inner side refers to the direction close to the pre-storage cavity 103 or the storage cavity 104. In other words, the wall of the second housing 12 that surrounds the pre-storage cavity 103 or the storage cavity 104, away from the first cover 2 or the second cover 6, forms the outer wall of the second housing 12.

[0072] Specifically, the control valve 4 includes a coil assembly 41, a valve core 42, and a coil support 43, with the coil assembly 41 located at one end of the control valve 4 (e.g., ...). Figure 10 The coil assembly 41 is located at the other end of the control valve 4 (as shown on the left end). Figure 10 (As shown on the right end), the coil bracket 43 is located between the coil assembly 41 and the valve core 42. The coil assembly 41 is connected to the valve core 42, and the coil assembly 41 controls the movement of the valve core 42 to control the dispensing of the second detergent. The coil bracket 43 is located outside the coil assembly 41, and the positioning groove 401 is located on the coil bracket 43. The positioning groove 401 cooperates with the positioning platform 120. It should be noted that the left end of the control valve 4 refers to the direction closer to the second cover 6 and farther away from the first cover 2, and the right end refers to the direction farther away from the second cover 6 and closer to the first cover 2.

[0073] More specifically, one end of the coil assembly 41 (e.g. Figure 10 The right end (as shown) is provided with a terminal 44 for connecting an external power supply. The coil support 43 includes a first part 431, a second part 432, and a third part 433. The first part 431 and the third part 433 are located on both sides of the coil assembly 41 along the moving direction of the valve core 42 (e.g., Figure 10 The second part 432 is located between the first part 431 and the third part 433, and the terminal 44 and the second part 432 are located on opposite sides of the coil assembly 41 (as shown on the left and right sides). Figure 10 The positioning groove 401 is located on one side of the second part 432 (as shown on the upper and lower sides). Figure 10As shown on the right side, the positioning groove is U-shaped. The positioning groove 401 cooperates with the positioning platform 120 to effectively prevent the control valve 4 from moving, thereby improving the reliability of the control valve 4's structural fixation. It should be noted that the U-shape is generally U-shaped. Due to errors in the manufacturing process or other factors, any structure that is generally U-shaped can fall within the scope of the U-shape that needs to be protected in this invention.

[0074] Furthermore, the second housing 12 is provided with a fixing part 7, which is located on one side of the second housing 12 (e.g., Figure 10 The lower side shown), the fixing part 7 is used to fix one side of the control valve 4 (as shown below). Figure 10 The positioning platform 120 is located at one end of the fixing part 7 (as shown on the lower side). Figure 10 As shown on the right end), the positioning platform cooperates with the 120 positioning groove 401 to effectively fix the control valve 4, prevent the control valve 4 from moving left and right, and improve the reliability of the control valve 4 structure fixation.

[0075] In some embodiments, the control valve 4 further includes a valve core support 45, one side of which (e.g.) Figure 10 The right side shown has at least one claw portion 451, the first part 431 has at least one groove 402, and the second part 432 has a groove 402 at the connection point with the first part 431. The groove 402 cooperates with the claw portion 451 to fix the valve core support 45, thereby making the internal structure of the control valve 4 more stable. More specifically, the first part 431 has four grooves 402. The first part 431 is a cuboid, and the grooves 402 are located at the four corners of the cuboid, which can better fix the valve core support 45, thereby making the valve core support 45 more stable. It can be understood that the number of claw portions 451 is four, and the number of grooves 402 is the same as the number of claw portions 451.

[0076] Specifically, the second housing 12 is provided with at least one boss 121, which extends along the direction of the claw portion 451 of the valve core support 45. The boss 121 cooperates with the outer wall of the claw portion 451 to fix the control valve 4, so that the control valve 4 will not move outward of the second housing 12, thereby improving the reliability of the control valve 4. There are two bosses 121 and two claw portions 451 that cooperate with the bosses 121.

[0077] In some embodiments, the second housing 12 further includes a stop 8, which is located on one side of the second housing 12 (e.g., Figure 10As shown on the left), the side wall of the stop 8 near the control valve 4 is flat. At least a portion of the side wall of the stop 8 near the control valve 4 is in contact with the side wall of the coil assembly 41 of the control valve 4 to prevent the control valve 4 from detaching from the second housing 12. This ensures that at least a portion of the control valve 4 is located inside the second housing 12 and fixed inside the second housing 12. The control valve 4 will not move out of the second housing 12, thereby improving the stability and reliability of the control valve 4 on the second housing 12.

[0078] The control valve 4 also includes a core assembly 46 and an elastic element 47. The core assembly 46 is connected to the valve core 42. The elastic element 47 is located between the coil assembly 41 and the valve core 42 and is used to reset the core assembly 46 and the valve core 42. The valve core 42 is provided with a sealing part 421, which cooperates with the second housing 12. The coil assembly 41 is used to drive the valve core 42 and the core assembly 46 to move, thereby controlling the dispensing of the second detergent in the second chamber 102. It is understood that the elastic element 47 can be, for example, a spring or other elastic material.

[0079] Specifically, the iron core assembly 46 is connected to the valve core 42, and the coil assembly 41 is used to drive the valve core 42 and the iron core assembly 46 to move. It can be understood that one end of the iron core assembly 46 (e.g., Figure 10 The right end (shown) is located within the coil assembly 41 and can move within the coil assembly 41 under the drive of the coil assembly 41. For example, the iron core assembly 46 moves within the coil assembly 41 in the left-right direction shown in Figure 10. Since the iron core assembly 46 is connected to the valve core 42, the valve core 42 moves together with the iron core assembly 46. According to the dispenser of the present invention, the sealing part 421 on the valve core 42 controls the process of the second detergent gradually moving from the storage chamber 104 through the transition chamber (not shown) to the second chamber 102.

[0080] In some embodiments, the other end of the core assembly 43 (e.g. Figure 10 The left end shown) is connected to one end of the elastic element 47 (such as the left end). Figure 10 The right end shown), the other end of the elastic element 47 (as shown on the right end), Figure 10 The left end shown) is connected to one end of the valve core 42 (as shown). Figure 10 (As shown on the right end). Its operation is as follows: the coil assembly 41 drives the iron core assembly 43 to move to the right, the iron core assembly 46 compresses the elastic element 47 to the right, and the valve core 42 moves to the right under the action of the elastic force of the elastic element 47; after the driving force of the coil assembly 41 disappears, the iron core assembly 43 resets under the action of the reverse elastic force of the elastic element 47, thereby driving the valve core 42 to reset.

[0081] A dishwasher includes a structure for dispensing a dishwasher dispenser, which allows the user to dispense a first detergent and a second detergent during dishwasher operation.
