[0024] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Refer to Figures 1 - 7 , the motor trigger structure of this dishwasher dispenser includes a drive motor 1, a control main board 2 and a material storage tray 3. A plurality of material storage cavities 31 for storing detergent are circumferentially distributed in the material storage tray 3. The transmission end of the drive motor 1 is connected with a transmission turntable 4 that can drive the material storage tray 3 to rotate. The control main board 2 is electrically connected with a touch switch 5. A touch foot portion 41 is provided on the transmission turntable 4. The touch foot portion 41 contacts or separates from the touch switch 5 by making a revolution around the center of the transmission turntable 4. The control main board 2 can control the drive motor 1 to drive the transmission turntable 4 and the touch foot portion 41 to rotate so that the touch foot portion 41 separates from the touch switch 5 until the touch foot portion 41 makes a full revolution and contacts the touch switch 5 again while the drive motor 1 stops rotating. The touch foot portion 41 enables the control main board 2 to receive signals by physically contacting the touch switch 5, thereby controlling the drive motor 1 again, simplifying the electrical control structure between the control main board 2 and the drive motor 1, and improving the reliability of equipment operation.

[0026] As Figure 1 , Figure 5 shown, in the initial state, the touch foot portion 41 contacts the touch switch 5. When it is necessary to start the drive motor 1, the control main board 2 sends a start signal to the drive motor 1, and the drive motor 1 starts to drive the transmission turntable 4 to drive the touch foot portion 41 to rotate. When the touch foot portion 41 makes a full revolution and contacts the touch switch 5 again, the control main board sends a shutdown signal to the drive motor 1, and the transmission turntable 4 stops rotating.

[0027] The control main board 2 sets relatively complex structures such as a timing module inside, which not only simplifies the electrical control structure between the control main board 2 and the drive motor 1. Since the shutdown of the drive motor 1 is completed by the physical contact between the touch foot portion 41 and the touch switch 5, that is, the rotation angle of the material storage tray 3 is the same every time the drive motor 1 starts and shuts down, the rotation accuracy of the material storage tray 3 can be improved every time.

[0028] Furthermore, the control main board 2 is arranged adjacent to the transmission turntable 4, the touch switch 5 is fixedly connected to the control main board 2, no additional wire is required between the touch switch 5 and the control main board 2, and no additional installation position needs to be set for the touch switch 5 inside the dispenser, simplifying the electrical connection structure between the touch switch 5 and the control main board 2.

[0029] Further, the tactile switch 5 includes a switch body 51 and a switch contact portion 52. The switch contact portion 52 can be retracted inward or extended outward relative to the switch body 51. A guiding inclined surface 521 is provided on the side of the switch contact portion 52 facing the rotation direction of the driving turntable 4. The guiding inclined surface 521 is inclined in the direction of the rotation of the driving turntable 4 and in the direction of the outward extension of the switch contact portion 52, which improves the smoothness of the connection process between the contact foot portion 41 and the switch contact portion 52 and reduces the chance of jamming between the two.

[0030] Further, the contact foot portion 41 is cylindrical in shape, and the outer arc surface of the contact foot portion 41 can contact or separate from the tactile switch 5, further improving the smoothness of the connection process between the contact foot portion 41 and the switch contact portion 52.

[0031] Further, the storage tray 3 is fixedly connected with a tooth rack 6. A number of concave tooth grooves 61 are evenly distributed on the tooth rack 6. Each storage cavity 31 corresponds to each concave tooth groove 61 one by one. The contact foot portion 41 can make the tooth rack 6 and the storage tray 3 rotate by itself through linkage with the concave tooth groove 61. The contact foot portion 41 can also drive the storage tray 3 to rotate through connection and cooperation with the concave tooth groove 61, making the function of the contact foot portion 41 more abundant, and there is no need to additionally provide other structures on the driving turntable 4 for driving the tooth rack 6.

[0032] Further, a connecting convex column 62 is provided at the central position of the tooth rack 6, and a connecting slot 32 corresponding to the connecting convex column 62 is provided on the side of the storage tray 3 facing the tooth rack 6. The connecting convex column 62 and the connecting slot 32 are respectively in a polygonal shape corresponding to each other. The connecting convex column 62 and the connecting slot 32 are inserted and matched to make the tooth rack 6 and the storage tray 3 detachably separable from each other, so that the storage tray 3 can be conveniently detached from the tooth rack 6, and it is more convenient for the user to clean the storage tray 3 or add detergent.

[0033] Further, the concave tooth grooves 61 are arranged along the radial direction of the tooth rack 6. The concave tooth grooves 61 are open at the radial outer side corresponding to the tooth rack 6. The revolution trajectory of the contact foot portion 41 is partially staggered with the revolution trajectory of the concave tooth grooves 61. The contact foot portion 41 enters or leaves the concave tooth grooves 61 through the openings of the concave tooth grooves 61 at the staggered positions of their revolution trajectories. The connection structure between the contact foot portion 41 and the concave tooth grooves 61 is relatively simple and not prone to failure.

[0034] As Figure 2 、 Figure 6 shown, the contact foot portion 41 first enters the concave tooth groove 61 and starts to interact with the tooth rack 6.

[0035] Further, as Figure 3 、 Figure 7 shown, after the contact foot portion 41 is separated from the concave tooth groove 61, the driving turntable 4 and the tooth rack 6 stop interacting, and the rotation of the tooth rack 6 is only completed through the cooperation between the contact foot portion 41 and the concave tooth groove 61.

[0036] The above embodiments are only the preferred solutions of the present utility model, and the present utility model may also have other implementation solutions. Those skilled in the art can also make equivalent deformations or substitutions without departing from the spirit of the present utility model, and these equivalent deformations or substitutions are all included within the scope defined by the claims of this application.
