[0032] 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.
[0033] like Figure 1-11As shown, the powder feeding mechanism of the quantitative powder dispenser of the dishwasher includes a powder feeding chamber 1, the powder feeding chamber 1 has a powder feeding port 11 that can allow dishwashing powder to leave the powder feeding chamber 1, a stirring component 2 that can stir the dishwashing powder is provided in the powder feeding chamber 1, and a powder feeding channel that can allow the dishwashing powder to flow to the powder feeding port 11 is formed between the stirring component 2 and the powder feeding port 11, the stirring component 2 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 to the dishwasher, and making the dishwasher have a better cleaning effect.
[0034] In some embodiments of the utility model, the stirring component 2 includes a stirring shaft 23 and a stirring blade group arranged on the stirring shaft 23. The stirring shaft 23 can drive the stirring blade group to rotate around the stirring shaft 23. The opening direction of the powder feeding port 11 is perpendicular to the axial direction of the stirring shaft 23. 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.
[0035] In a further scheme of the utility model, the powder feeding port 11 is arranged at the lower side of the powder feeding chamber 1, the stirring blade group is arranged at the upper position of the powder feeding chamber 1, and the stirring assembly includes a plurality of first stirring blades 21 and second stirring blades 22. The first stirring blades 21 and the second stirring blades 22 are respectively distributed along the length direction of the stirring shaft 23, so that the dishwashing powder at different positions corresponding to the length direction of the stirring shaft 23 in the powder feeding chamber 1 can obtain the stirring effect at the same time.
[0036] The first stirring blade 21 is in the shape of a long plate, and the vertical projection of the first stirring blade 21 is staggered from the powder feeding port 11. The first stirring blade 21 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 23.
[0037] The second stirring blade 22 is in a cross shape and is provided with a hollow hole 221. The vertical projection of the second stirring blade 22 coincides with the powder feeding port 11. The second stirring blade 22 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 22 stirs, part of the dishwashing powder can pass through the hollow hole 221, so that the dishwashing powder can be more easily broken up.
[0038] In a further embodiment of the present invention, the projections of the first stirring blade 21 and the second stirring blade 22 along the length direction of the stirring shaft 23 are staggered with each other, so that the forces at different positions on the stirring shaft 23 are more uniform, and the forces at different positions of the dishwashing powder along the length direction of the stirring shaft 23 are also staggered accordingly, which is more conducive to breaking up the dishwashing powder.
[0039] The projections of the first stirring blade 21 and the second stirring blade 22 along the length direction of the stirring shaft 23 are staggered at an angle a, a=45°.
[0040] In a further solution of the present invention, a guide plate 3 is provided on the lower side of the powder delivery chamber 1. The cross-section of the guide plate 3 is in a V-shape with the opening facing upward. The powder delivery port 11 is arranged at the bottom position of the guide plate 3, so that the dishwashing powder in the powder delivery chamber 1 can flow to the powder delivery port 11 more easily.
[0041] In a further solution of the present invention, a driving motor 4 is provided on the outside of the powder feeding chamber 1, and a transmission member 41 is provided between the driving motor 4 and the stirring shaft 23. The transmission member 41 is respectively connected to the stirring shaft 23 and the driving motor 4. The user can more easily control the stirring effect of the powder feeding chamber 1, so that the powder feeding device has a higher degree of automation.
[0042] In a further scheme of the utility model, the powder feeding chamber 1 has a powder feeding port 12 that can allow dishwashing powder to enter the powder feeding chamber 1, and the powder feeding port 12 is provided with a movable blocking cover 5 that can be movably connected thereto. The movable blocking cover 5 is movably connected to the powder feeding port 12 to enable the powder feeding port 12 to be opened or closed. When dishwashing powder needs to be added to the powder feeding chamber 1, the movable blocking cover 5 can be rotated to open the powder feeding port 11. After the dishwashing powder is added, the movable blocking cover 5 can be rotated again to close the powder feeding port 11.
[0043] In a further solution of the utility model, a first snap portion 121 is provided at a peripheral position of the powder feeding port 12, and a second snap portion 51 corresponding to the first snap portion 121 is provided on the movable cover 5. The first snap portion 121 is connected and cooperated with the second snap portion 51 to enable the movable cover 5 to keep the powder feeding port 12 closed, thereby improving the stability of the movable cover 5 when closing the powder feeding port 12 and preventing it from accidentally opening the powder feeding port 12 during the working process.
[0044] In a further solution of the utility model, a connecting shaft 52 is provided on the lower side of the movable cover 5 along the horizontal direction. The movable cover 5 can rotate around the connecting shaft 52 to open the powder feeding port 12 from top to bottom. When the movable cover 5 is opened to add dishwashing powder, the movable cover 5 remains connected to the periphery of the powder feeding port 12 on the lower side, so the dishwashing powder is not easy to spill on other positions outside the movable cover 5.
[0045] In a further scheme of the utility model, a sealing rib 122 is provided at the peripheral position of the powder feeding port 12, and a sealing ring 53 corresponding to the sealing rib 122 is provided on the movable cover 5. The movable cover 5 closes the powder feeding port 12 so that the sealing ring 53 is tightly connected with the sealing rib 122, and a flushing chamber 54 is formed at a position below the sealing ring 53 and the sealing rib 122 on the side of the movable cover 5 facing the powder feeding port 12. A flushing hole 55 is provided on the movable cover 5 at a position corresponding to the flushing chamber 54. Liquid water can enter the flushing chamber 54 through the flushing hole 55 to flush the residual dishwashing powder in the flushing chamber 54. The sealing ring 53 cooperates with the sealing rib 122 to prevent liquid from entering the powder feeding chamber 1.
