[0002] For the ice discharging device of a conventional ice maker, the motor adopting the screw ice pushing method needs to control the rotation direction of the screw, and usually a DC motor with a high controllable rotation direction and high cost is used. Content of the Utility Model

[0003] To solve the above problems, the present technical solution provides a driving structure for an ice discharging device of an ice maker.

[0004] To achieve the above object, the present technical solution is as follows:

[0005] A driving structure for an ice discharging device of an ice maker, comprising

[0006] a housing, inside which an ice making cavity is provided;

[0007] an ice discharging mechanism, which includes a push rod arranged in the ice making cavity and an AC motor for driving the push rod;

[0009] For a driving structure for an ice discharging device of an ice maker as described above, the directional mechanism includes a dial arranged at the output end of the AC motor and a limiting component. When the output end of the AC motor drives the dial to rotate forward, the limiting component gives way to the dial to allow the dial to continue rotating forward; when the dial rotates backward, the limiting component limits the dial to prevent the dial from continuing to rotate backward.

[0010] For a driving structure for an ice discharging device of an ice maker as described above, the limiting component includes a pin extending into the rotation path of the dial. When the dial rotates forward, it pushes the pin out of the rotation path; when the dial rotates backward, it abuts against the pin, and the pin remains in the rotation path.

[0011] For a driving structure for an ice discharging device of an ice maker as described above, the limiting component further includes a limiting groove for the pin to slide, and an elastic member for pressing the pin towards the direction close to the dial.

[0012] For a driving structure for an ice discharging device of an ice maker as described above, the limiting component includes a limiting groove for the pin to slide, and the limiting groove is arranged downward to allow the pin to enter the rotation path of the dial under the action of gravity.

[0013] A driving structure for an ice discharging device of an ice maker as described above, wherein a first inclined surface is provided on the paddle, and a second inclined surface is provided on the pin. When the first inclined surface contacts the second inclined surface, the pin is pushed towards the direction of retracting into the limiting groove.

[0014] A driving structure for an ice discharging device of an ice maker as described above, wherein a first pressing surface is provided on the paddle, and a second pressing surface is provided on the pin. When the first pressing surface contacts the second pressing surface, the pin is pressed in a direction perpendicular to the sliding direction of the pin.

[0015] A driving structure for an ice discharging device of an ice maker as described above, wherein the orientation mechanism further includes a microswitch electrically connected to the AC motor. The microswitch is triggered once when the paddle rotates one circle, so as to trigger the AC motor to stop after a preset number of circles.

[0016] A driving structure for an ice discharging device of an ice maker as described above, wherein a limiting portion is provided on the pin, and the limiting portion cooperates with the limiting groove to limit the pin from disengaging from the limiting groove.

[0017] A driving structure for an ice discharging device of an ice maker as described above, wherein the orientation mechanism further includes a microswitch, which is correspondingly arranged with the limiting portion. When the pin retracts into the limiting groove, the limiting portion is driven to move synchronously to trigger the microswitch.

[0018] The beneficial effects of this application are:

[0019] The present utility model provides a driving structure for an ice discharging device of an ice maker, which uses a low-cost AC single machine as a power source. However, since the starting rotation direction of the AC motor is random and cannot meet the requirement that the push rod needs to have a fixed rotation direction when pushing the ice, an orientation mechanism is added so that the push rod can rotate in a fixed direction to push out the ice. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 2 is a schematic structure of the present utility model Figure 2 。 DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] A driving structure for an ice discharging device of an ice maker, comprising

[0025] A housing 1, which is provided with an ice making cavity 11 therein;

[0026] An ice discharging mechanism 2, which includes a push rod 21 arranged in the ice making cavity 11 and an alternating current motor 22 for driving the push rod 21;

[0027] An orientation mechanism 3, which is used to keep the alternating current motor 22 rotating in the forward direction.

[0028] The present utility model provides a driving structure for an ice discharging device of an ice maker, which uses a low-cost alternating current single machine as a power source. However, because the starting rotation direction of the alternating current motor is random and cannot meet the requirement that the push rod needs to have a fixed rotation direction when pushing the ice, an orientation mechanism is added, so that the push rod can rotate in a fixed direction to push out the ice.

[0029] Further, as a preferred implementation manner of this solution rather than a limitation, the orientation mechanism 3 includes a dial 31 arranged on the output end of the alternating current motor 22 and a limit component 32. When the output end of the alternating current motor 22 drives the dial 31 to rotate forward, the limit component 32 gives way to the dial 31 to allow the dial 31 to continue rotating forward; when the dial 31 rotates backward, the limit component 32 limits the dial 31 to prevent the dial 31 from continuing to rotate backward. According to the characteristics of the alternating current motor, when it is subjected to a large resistance, the alternating current motor will automatically reverse. Therefore, by not hindering the forward rotation and hindering the reverse rotation, the alternating current motor is kept rotating forward. The forward rotation direction can be the clockwise direction or the counterclockwise direction, specifically determined according to the pushing direction of the push rod.

[0030] Further, as a preferred implementation manner of this solution rather than a limitation, the limit component 32 includes a pin 321 extending into the rotation path of the dial 31. When the dial 31 rotates forward, it pushes the pin 321 out of the rotation path; when the dial 31 rotates backward, it abuts against the pin 321, and the pin 321 remains in the rotation path. By using the way of the pin abutting to hinder the rotation of the dial.

[0031] Further, as a preferred implementation manner of this solution rather than a limitation, the limiting component 32 further includes a limiting groove 322 for the pin 321 to slide, and an elastic member 320 for pressing the pin 321 in the direction close to the dial 31. When the dial rotates forward, the pin is pushed, causing the pin to compress the elastic member, thereby making way.

[0032] Further, as a preferred implementation manner of this solution rather than a limitation, the limiting component 32 includes a limiting groove 322 for the pin 321 to slide, and the limiting groove 322 is arranged downward for the pin 321 to enter the rotation path of the dial 31 under the action of gravity.

[0033] Further, as a preferred implementation manner of this solution rather than a limitation, a first inclined surface 311 is provided on the dial 31, and a second inclined surface 323 is provided on the pin 321. When the first inclined surface 311 contacts the second inclined surface 323, the pin 321 is pushed in the direction of retracting into the limiting groove 322. Pushing is performed by means of the cooperation of inclined surfaces to reduce resistance.

[0034] Further, as a preferred implementation manner of this solution rather than a limitation, a first pressing surface 312 is provided on the dial 31, and a second pressing surface 324 is provided on the pin 321. When the first pressing surface 312 contacts the second pressing surface 324, the pin 321 is pressed in a direction perpendicular to the sliding direction of the pin 321. This is beneficial to preventing the pin from being pushed.

[0035] Further, as a preferred implementation manner of this solution rather than a limitation, the orientation mechanism 3 further includes a microswitch 33 electrically connected to the AC motor 22. The microswitch 33 is triggered once when the dial 31 rotates one circle, so as to trigger the AC motor 22 to stop after a preset number of circles. The number of rotation circles of the push rod can be recorded.

[0036] Further, as a preferred implementation manner of this solution rather than a limitation, a limiting portion 325 is provided on the pin 321, and the limiting portion 325 cooperates with the limiting groove 322 to limit the pin 321 from disengaging from the limiting groove 322. At the same time, the pin is restricted to avoid affecting the rotation of the AC motor.

[0037] Further, as a preferred implementation manner of this solution rather than a limitation, the orientation mechanism 3 further includes a microswitch 33. The microswitch 33 is arranged corresponding to the limiting portion 325. When the pin 321 retracts into the limiting groove 322, the limiting portion 325 is driven to move synchronously to trigger the microswitch 33.

[0038] The above are only the preferred embodiments of the present application, and are not intended to limit the scope of implementation of the present application. All other embodiments with the same or similar principles and basic structures as the present application are within the protection scope of the present application.
