[0047] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0048] like Figure 1-20 As shown, the quantitative powder dispenser for a dishwasher comprises a powder feeding chamber 1 and a powder feeding chamber 2. A powder feeding port 11 is provided between the powder feeding chamber 1 and the powder feeding chamber 2. When in use, the user first puts the dishwashing powder into the powder feeding chamber 1, then the powder enters the powder feeding chamber 2 through the powder feeding port 11, and finally is discharged outward through the powder feeding port 21 of the powder feeding chamber 2.

[0049] A stirring component is provided in the powder feeding chamber 1, which can stir the dishwashing powder by moving relative to the powder feeding chamber 1. A powder feeding channel is formed between the stirring component and the powder feeding port 11, which can allow the dishwashing powder to flow to the powder feeding port 11. The stirring component can continuously stir the dishwashing powder in the powder feeding chamber 1 to prevent the dishwashing powder from forming lumps, so that the dishwashing powder in the powder feeding chamber 1 can leave the powder feeding chamber 1 more smoothly from the powder feeding port 11, thereby improving the stability of the dispenser in feeding dishwashing powder into the dishwasher and improving the cleaning effect of the dishwasher.

[0050] The powder feeding chamber 2 has a powder feeding port 21 for allowing dishwashing powder to leave, and a powder pushing component is provided at a position between the powder feeding port 11 and the powder feeding port 21 in the powder feeding chamber 2, which can push the dishwashing powder from the powder feeding port 11 to the powder feeding port 21 by moving relative to the powder feeding chamber 2. The powder pushing component can improve the stability of the dishwashing powder when it flows from the powder feeding port 11 to the powder feeding port 21, so that the dishwashing powder can be discharged from the powder feeding port 21 according to a preset amount, thereby improving the cleaning effect of the dishwasher.

[0051] A driving motor 3 is provided on the outside of the powder feeding chamber 1 and the powder feeding chamber 2, and a linkage is provided between the driving motor 3 and the stirring assembly and the powder pushing assembly. The driving motor 3 drives the stirring assembly and the powder pushing assembly to move relative to the powder feeding chamber 1 and the powder feeding chamber 2 respectively through the linkage. The driving motor 3 can drive the stirring assembly and the powder pushing assembly at the same time through the linkage, without the need for additional driving equipment, thereby reducing the cost of the distributor and relatively reducing the overall volume of the distributor.

[0052] In some embodiments of the utility model, the stirring component includes a stirring shaft 43 and a stirring blade group arranged on the stirring shaft 43. The stirring shaft 43 can drive the stirring blade group to rotate around the stirring shaft 43. The stirring blade group can stir the dishwashing powder in the powder feeding chamber 1 by rotating, thereby reducing the chance of the dishwashing powder forming lumps.

[0053] The stirring blade group includes a plurality of first stirring blades 41 and second stirring blades 42, which are respectively distributed along the length direction of the stirring shaft 43, so that the dishwashing powder at different positions corresponding to the length direction of the stirring shaft 43 in the powder feeding chamber 1 can obtain the stirring effect at the same time.

[0054] The first stirring blade 41 is in the shape of a long plate, and the vertical projection of the first stirring blade 41 is staggered from the powder feeding port 11. The first stirring blade 41 stirs the dishwashing powder relatively far away from the powder feeding port 11, and the resistance is relatively small, which can reduce the difficulty of rotating the stirring shaft 43.

[0055] The second stirring blade 42 is in a cross shape and is provided with a hollow hole 421. The vertical projection of the second stirring blade 42 coincides with the powder feeding port 11. The second stirring blade 42 stirs the dishwashing powder relatively close to the powder feeding port 11 more fully, so that the dishwashing powder can flow to the powder feeding port 11 more easily. When the second stirring blade 42 stirs, part of the dishwashing powder can pass through the hollow hole 421, so that the dishwashing powder can be more easily broken up.

[0056] In some embodiments of the utility model, the powder pushing assembly includes a powder pushing screw 51, on which is provided a powder pushing sheet 52, which is in a spiral shape, and whose radial width is greater than the diameter of the powder pushing screw 51, and on which are formed a plurality of powder pushing gaps 53 which are spaced apart from each other and distributed along the axial direction of the powder pushing screw 51. When the powder pushing screw 51 drives the powder pushing sheet 52 to rotate, the powder pushing gap 53 can make a certain amount of dishwashing powder move along the axial direction of the powder pushing screw 51, so that the dishwashing powder can be discharged from the powder feeding port 21 according to a certain amount.

[0057] In some embodiments of the utility model, the linkage includes a stirring joint 44, a screw joint 54 and a transmission belt 31. The stirring joint 44 and the screw joint 54 are respectively connected and fixed to the stirring shaft 43 and the powder pushing screw 51. The screw joint 54 is transmission connected to the drive motor 3. The transmission belt 31 is transmission connected to the stirring joint 44 and the screw joint 54 respectively. The transmission belt 31 can play the effect of synchronizing the stirring joint 44 and the screw joint 54, so that the stirring shaft 43 and the powder pushing screw 51 can rotate synchronously.

[0058] As an equivalent transformation, the driving motor 3 may also be directly connected to the stirring joint 44 , and the stirring joint 44 then drives the screw joint 54 to rotate through the transmission belt 31 .

[0059] In some embodiments of the utility model, the powder feeding port 21 is movably connected to a movable baffle 6, and the movable baffle 6 is connected to a driver 7. The driver 7 can move the movable baffle 6 relative to the powder feeding port 21 to open or close the powder feeding port 21. The movable baffle 6 is controlled by the driver 7 to open or close the powder feeding port 21, so that the user can more easily control the amount and timing of detergents such as dishwashing powder leaving the powder feeding chamber 2 from the powder feeding port 21, thereby improving the stability of detergents such as dishwashing powder leaving the powder feeding chamber 2 from the powder feeding port 21 and improving the cleaning effect of the dishwasher.

[0060] The movable baffle 6 is provided with a joint portion 61, and the joint portion 61 is provided with a hollow groove 611 extending radially from the center position of the joint portion 61. The hollow groove 611 is connected and cooperated with the driver 7. When dishwashing powder falls on the movable baffle 6, the gravity on the movable baffle 6 increases. The hollow groove 611 can allow the connection position between the driver 7 and the joint portion 61 to have a certain displacement space, thereby preventing the rotating shaft of the driver 7 from being subjected to excessive force and deforming.

[0061] In some embodiments of the utility model, the cross-sections of the powder feeding port 21 and the movable baffle 6 are circular, and the movable baffle 6 has a rotating shaft 63 passing through the center position of the powder feeding port 21, and the rotating shaft 63 extends out of the outside of the powder feeding port 21 and is connected to the driver 7 in a transmission manner. When the driver 7 drives the movable baffle 6 to rotate perpendicular to the plane where the powder feeding port 21 is located through the rotating shaft 63, it is equivalent to the powder feeding port 21 being opened. When the driver 7 drives the movable baffle 6 to rotate parallel to the plane where the powder feeding port 21 is located through the rotating shaft 63, it is equivalent to the powder feeding port 21 being closed.

[0062] In some embodiments of the utility model, the rotating shaft 63 is connected to a trigger part 62, and the trigger part 62 forms a radial spacing with the rotating shaft 63. The trigger part 62 can rotate around the rotating shaft 63, and a first trigger switch 71 and a second trigger switch 72 are provided on the rotation trajectory of the trigger part 62. The first trigger switch 71 and the second trigger switch 72 are electrically connected to the drive motor 3 respectively.

[0063] like Fig.14 As shown, the driver 7 drives the rotating shaft 63 to rotate forward until the movable baffle 6 opens the powder feeding port 21, and the trigger part 62 abuts against the first trigger switch 71 to make the first trigger switch 71 and the driving motor 3 conductive and start the driving motor 3, so that the driving motor 3 can be started synchronously when the movable baffle 6 opens the powder feeding port 21, thereby preventing the dishwashing powder from being unable to be discharged from the powder feeding port 21 in time after the powder feeding port 21 is opened.

[0064] like Fig.15As shown, the driver 7 drives the rotating shaft 63 to rotate in the opposite direction until the movable baffle 6 closes the powder feeding port 21, and the trigger part 62 abuts against the second trigger switch 72 to disconnect the second trigger switch 72 from the driving motor 3 and shut down the driving motor 3, so that the driving motor 3 can be shut down synchronously when the movable baffle 6 closes the powder feeding port 21, thereby preventing dishwashing powder from continuing to flow into the powder feeding port 21 when the powder feeding port 21 is closed, thereby reducing the chance of blockage of the powder feeding port 21.

[0065] The vertical projection of the driver 7 at least partially overlaps with the powder feeding chamber 2, the horizontal projection of the drive motor 3 at least partially overlaps with the powder feeding chamber 2 and the movable baffle 6, and the vertical projection of the powder delivery chamber 1 at least partially overlaps with the powder feeding chamber 2 and the drive motor 3, respectively. The space and the house reasonably utilize the internal space position of the distributor as a whole to make the equipment more compact.

[0066] In some embodiments of the utility model, the powder delivery chamber 1 has a powder inlet 12 for allowing dishwashing powder to enter therein, and the powder inlet 12 is provided with a movable baffle 8 movably connected thereto, and the movable baffle 8 is movably connected to the powder inlet 12 to enable the powder inlet 12 to be opened or closed. When dishwashing powder needs to be added to the powder delivery chamber 1, the movable baffle 8 can be rotated to open the powder inlet 12, and after the dishwashing powder is added, the movable baffle 8 can be rotated again to close the powder inlet 12.

[0067] In some embodiments of the utility model, a first snapping portion 121 is provided at a peripheral position of the powder inlet 12, and a second snapping portion 81 corresponding to the first snapping portion 121 is provided on the movable cover 8. The connection and cooperation between the first snapping portion 121 and the second snapping portion 81 can enable the movable cover 8 to keep the powder inlet 12 closed, thereby improving the stability of the movable cover 8 when closing the powder inlet 12 and preventing it from accidentally opening the powder inlet 12 during operation.

[0068] In some embodiments of the utility model, a connecting shaft 82 is provided on the lower side of the movable cover 8 along the horizontal direction. The movable cover 8 can rotate around the connecting shaft 82 to open the powder inlet 12 from top to bottom. When the movable cover 8 is opened to add dishwashing powder, the movable cover 8 remains connected to the periphery of the powder inlet 12 on the lower side, so the dishwashing powder is not easy to spill on other positions outside the movable cover 8.

[0069] A sealing rib 122 is provided at the peripheral position of the powder inlet 12, and a sealing ring 83 corresponding to the sealing rib 122 is provided on the movable cover 8. When the movable cover 8 closes the powder inlet 12, the sealing ring 83 can be tightly connected with the sealing rib 122, and a flushing chamber 84 is formed at the position below the sealing ring 83 and the sealing rib 122 on the side of the movable cover 8 facing the powder inlet 12. A flushing hole 85 is provided on the movable cover 8 at a position corresponding to the flushing chamber 84, and liquid water can enter the flushing chamber 84 through the flushing hole 85 to flush the residual dishwashing powder in the flushing chamber 84. The sealing ring 83 cooperates with the sealing rib 122 to prevent liquid from entering the powder feeding chamber 1.

[0070] The above is a preferred embodiment of the utility model, which shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
