[0036] 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.
[0037] like Figure 1-13 As shown, the powder discharging mechanism of the quantitative powder dispenser of the dishwasher comprises a powder feeding chamber 1, the powder feeding chamber 1 has a powder feeding port 11 for allowing dishwashing powder to leave the powder feeding chamber 1, the powder feeding port 11 is movably connected with a movable baffle 2, the movable baffle 2 is connected with a driver 3, the driver 3 can make the movable baffle 2 move relative to the powder feeding port 11 to open or close the powder feeding port 11, and the movable baffle 2 is controlled by the driver 3 to open or close the powder feeding port 11, so that the user can more easily control the amount and timing of dishwashing powder and other detergents leaving the powder feeding chamber 1 from the powder feeding port 11, thereby improving the stability of dishwashing powder and other detergents leaving the powder feeding chamber 1 from the powder feeding port 11, and improving the cleaning effect of the dishwasher.
[0038] In some embodiments of the utility model, the cross-sections of the powder feeding port 11 and the movable baffle 2 are circular, and the movable baffle 2 has a rotating shaft 21 passing through the center position of the powder feeding port 11, and the rotating shaft 21 extends out of the outside of the powder feeding port 11 and is connected to the driver 3 in transmission. When the driver 3 drives the movable baffle 2 to rotate perpendicular to the plane where the powder feeding port 11 is located through the rotating shaft 21, it is equivalent to the powder feeding port 11 being opened. When the driver 3 drives the movable baffle 2 to rotate parallel to the plane where the powder feeding port 11 is located through the rotating shaft 21, it is equivalent to the powder feeding port 11 being closed. In addition, the way in which the movable baffle 2 rotates around the rotating shaft 21 can also relatively reduce the space occupied by the movable baffle 2.
[0039] A joint portion 221 is provided on the rotating shaft 21, and a hollow groove 2211 is provided on the joint portion 221 and extends radially from the center position of the joint portion 221. The hollow groove 2211 is connected and cooperated with the driver 3. When dishwashing powder falls on the movable baffle 2, the gravity exerted on the movable baffle 2 increases. The hollow groove 2211 can allow the connection position between the driver 3 and the joint portion 221 to have a certain displacement space, thereby preventing the rotating shaft of the driver 3 from being subjected to excessive force and deforming.
[0040] In some embodiments of the utility model, a powder outlet chamber 8 is provided on the outer side of the bottom of the powder feeding port 11, the vertical projection of the rotating shaft 21 coincides with the powder outlet chamber 8, and the driver 3 is arranged on the outer side of the powder outlet chamber 8, which relatively increases the width and volume of the powder outlet chamber 8, so that the dishwashing powder can be more evenly put into the dishwasher.
[0041] In some embodiments of the utility model, the powder feeding chamber 1 also has a powder feeding port 12 for allowing dishwashing powder to enter the powder feeding chamber 1, and a powder pushing component capable of pushing the dishwashing powder from the powder feeding port 12 to the powder feeding port 11 is provided at a position corresponding to the powder feeding port 12 and the powder feeding port 11 in the powder feeding chamber 1. The powder pushing component can improve the stability of the dishwashing powder when it flows from the powder feeding port 12 to the powder feeding port 11, so that the dishwashing powder can be discharged from the powder feeding port 11 according to a preset amount, thereby improving the cleaning effect of the dishwasher.
[0042] In some embodiments of the utility model, the powder pushing assembly includes a powder pushing screw 41, on which is provided a powder pushing sheet 42, which is in a spiral shape, and whose radial width is greater than the diameter of the powder pushing screw 41, and on which are formed a plurality of powder pushing gaps 43 which are spaced apart from each other and distributed along the axial direction of the powder pushing screw 41. When the powder pushing screw 41 drives the powder pushing sheet 42 to rotate, the powder pushing gap 43 can make a certain amount of dishwashing powder move along the axial direction of the powder pushing screw 41, so that the dishwashing powder can be discharged from the powder feeding port 11 in a certain amount.
[0043] In some embodiments of the utility model, the powder pushing screw 41 is transmission-connected to a driving motor 5, and the driving motor 5 drives the powder pushing sheet 42 to rotate around the powder pushing screw 41 through the powder pushing screw 41, so that the user can more easily control the powder feeding effect of the powder feeding chamber 1, making the powder feeding device more automated.
[0044] In some embodiments of the utility model, the rotating shaft 21 is connected to a trigger part 22, and the trigger part 22 forms a radial distance with the rotating shaft 21. The trigger part 22 can rotate around the rotating shaft 21, and a first trigger switch 31 and a second trigger switch 32 are provided on the rotation trajectory of the trigger part 22. The first trigger switch 31 and the second trigger switch 32 are electrically connected to the drive motor 5 respectively.
[0045] like Figure 2 , Figure 7 As shown, the driver 3 drives the rotating shaft 21 to rotate forward until the movable baffle 2 opens the powder feeding port 11, and the trigger part 22 abuts against the first trigger switch 31 to make the first trigger switch 31 and the driving motor 5 conductive and start the driving motor 5, so that the driving motor 5 can be started synchronously when the movable baffle 2 opens the powder feeding port 11, thereby preventing the dishwashing powder from being unable to be discharged from the powder feeding port 11 in time after the powder feeding port 11 is opened.
[0046] like Figure 3 , Figure 8 As shown, the driver 3 drives the rotating shaft 21 to rotate in the opposite direction until the movable baffle 2 closes the powder feeding port 11, and the trigger part 22 abuts against the second trigger switch 32 to disconnect the second trigger switch 32 from the driving motor 5 and shut down the driving motor 5, so that the driving motor 5 can be shut down synchronously when the movable baffle 2 closes the powder feeding port 11, thereby preventing dishwashing powder from continuing to flow into the powder feeding port 11 when the powder feeding port 11 is closed, thereby reducing the chance of blockage of the powder feeding port 11.
[0047] In some embodiments of the utility model, a powder delivery chamber 6 for storing dishwashing powder is provided on the upper outer side of the powder feeding chamber 1, and a stirring component for stirring the dishwashing powder is provided in the powder delivery chamber 6. The powder delivery port 12 is arranged between the powder feeding chamber 1 and the powder delivery chamber 6. The stirring component can continuously stir the dishwashing powder in the powder delivery chamber 6 to prevent the dishwashing powder from forming lumps, so that the dishwashing powder in the powder delivery chamber 6 can more smoothly leave the powder delivery chamber 6 from the powder delivery port 12 and enter the powder feeding chamber 1, thereby improving the stability of the dispenser in feeding dishwashing powder to the dishwasher and improving the cleaning effect of the dishwasher.
[0048] In some embodiments of the utility model, the stirring assembly includes a stirring shaft 73 and a stirring blade group arranged on the stirring shaft 73. The stirring shaft 73 can drive the stirring blade group to rotate around the stirring shaft 73. The stirring blade group can stir the dishwashing powder in the powder feeding chamber 6 by rotating, thereby reducing the chance of the dishwashing powder forming lumps.
[0049] In some embodiments of the utility model, the stirring assembly includes a plurality of first stirring blades 71 and second stirring blades 72, and the first stirring blades 71 and the second stirring blades 72 are respectively distributed along the length direction of the stirring shaft 73, so that the dishwashing powder at different positions corresponding to the length direction of the stirring shaft 73 in the powder feeding chamber 6 can obtain the stirring effect at the same time.
[0050] The first stirring blade 71 is in the shape of a long plate, and the vertical projection of the first stirring blade 71 is staggered from the powder feeding port 12. The first stirring blade 71 stirs the dishwashing powder relatively far away from the powder feeding port 12, and the resistance is relatively small, which can reduce the difficulty of rotating the stirring shaft 73.
[0051] The second stirring blade 72 is in a cross shape, and the vertical projection of the second stirring blade 72 coincides with the powder feeding port 12 . The second stirring blade 72 stirs the dishwashing powder relatively close to the powder feeding port 12 more fully, so that the dishwashing powder can flow to the powder feeding port 12 more easily.
[0052] 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.
