[0005] The ice pushing plate includes a plate body and a suspension arm. The limiting device is a limiting rib plate arranged on the first side of the ice making tray. When the ice making tray rotates by an angle A during the de-icing stroke, the bottom end of the limiting rib plate touches the plate body of the ice pushing plate.

[0006] The limiting rib plate is arranged perpendicular to the wall of the first side of the ice making tray.

[0007] A pair of shaft sleeves are arranged on the first side, and the suspension arm extends into the shaft sleeve. The suspension arm and the inner diameter clearance of the shaft sleeve are matched, so that the ice pusher plate can hang freely by its own weight without external force.

[0008] A coupling is arranged at the first end of the ice tray along the length direction, and the coupling is connected to the motor shaft; a connecting block is arranged at the second end of the ice tray along the length direction, and a switch plate is sleeved on the connecting block, and a first switch button and a second switch button are arranged on the switch plate.

[0009] The switch plate is in a teardrop shape, and the connecting block is connected to the large end of the switch plate so that the switch plate and the ice tray rotate synchronously. The first switch button and the second switch button are respectively arranged on both sides of the small end of the switch plate, and the first switch button and the second switch button are perpendicular to the side wall of the switch plate.

[0010] A concave cavity is arranged at the large end of the switch plate, a protrusion adapted to extend into the concave cavity is arranged at the connecting block, and a positioning structure for preventing the protrusion from idling is arranged at the concave cavity.

[0011] A bevel plate is arranged near the second end of the ice tray, and micro switches are arranged on two right-angle beams of the bevel plate corresponding to the first switch button and the second switch button respectively, and the micro switches are connected to the main control board signal.

[0012] The utility model has the following beneficial effects:

[0013] When defrosting, ice cubes generally fall from the front of the ice storage drawer first. By arranging a freely suspended ice pushing plate and a limiting rib plate on the ice tray, the bottom end of the limiting rib plate touches the body of the ice pushing plate after the ice tray rotates by angle A during the defrosting stroke, thereby limiting the ice pushing plate from being blocked by the ice cubes in the drawer and rotating in the direction opposite to the defrosting flipping direction, and instead pushing the blocked ice cubes to the back of the ice storage drawer.

[0014] The ice-making device is provided with a micro switch forming an angle of about 90 degrees at one end near the ice tray, which provides an accurate control basis for the starting and ending strokes of the angular displacement of the ice tray's flipping stroke. The switch board has a large and small end structure, and two switch buttons extend vertically on both sides of the small end. When the switch board reaches the stop point, the button can safely and accurately press the micro switch, so that the main control board can accurately output the control signal, thereby stopping the operation of the flipping motor.

An ice pusher plate 4 is hung on the first side of the ice tray. A limit device is provided on the ice tray. The limit device limits the ice pusher plate from rotating in the opposite direction of the deicing flipping direction after the ice tray rotates by an angle A during the deicing process. Figure 4 As shown in the B direction, after the ice tray 2 rotates the angular displacement A, due to the blocking of the limit device, the ice pushing plate 4 and the ice tray complete the subsequent ice-removing and flipping stroke together in a fixed relative position. At this time, if there are ice cubes piled on the front side of the ice storage drawer from the previous time, the ice pushing plate can push the ice cubes that are piled too high to the back side of the drawer, thereby improving the space utilization rate of the drawer.

[0027] The rear side of the ice storage drawer 1 is deeper than the front side, and the bottom of the front side has a slope, and a water hole 11 is arranged on the slope.

[0028] like Figure 3 , 5 As shown, the ice pusher 4 includes a plate body 41 and a suspension arm 42. The limiting device is a limiting rib plate 21 arranged on the first side of the ice tray. When the ice tray rotates an angle A during the deicing stroke, the bottom end of the limiting rib plate touches the plate body 41 of the ice pusher. The limiting rib plate 21 is arranged perpendicular to the wall body of the first side 20 of the ice tray. A pair of sleeves 25 are arranged at the bottom of the outer wall of the first side 20 of the ice tray 2. The suspension arm 42 extends into the sleeve 25. The suspension arm and the inner diameter clearance of the sleeve are matched, so that the plate body 41 can be easily turned over, and the ice pusher can hang freely under its own weight without external force. In order to facilitate installation, the sleeve 25 has an opening, and the opening size is smaller than the diameter of the suspension arm. When the suspension arm is installed, the sleeve is inserted from the opening by external force. After installation, the sleeve opening is restored to its original state so that the suspension arm is installed in the sleeve. A coupling 22 is provided at the first end of the ice tray 2 along the length direction, and the coupling 22 is connected to the motor shaft of the motor 5; a connecting block is provided at the second end of the ice tray along the length direction, and a switch plate 6 is sleeved on the connecting block, and a first switch button 65 and a second switch button 66 are provided on the switch plate 6.

[0029] See also Figure 5-6The switch plate 6 is in a teardrop shape, and the connecting block is connected to the large end 61 of the switch plate, so that the switch plate and the ice tray rotate synchronously. The first switch button 65 and the second switch button 66 are perpendicular to the side wall of the switch plate and are respectively arranged on both sides of the small end 62 of the switch plate. A concave cavity 63 is arranged at the large end 61 of the switch plate, and the connecting block is provided with a protrusion 23 adapted to extend into the concave cavity, and a positioning structure 631 is arranged in the concave cavity 63 to prevent the protrusion 23 from idling.

Figure 1 When ice-removing is required, the motor drives the ice-making tray 2 to flip clockwise, and the switch plate 6 rotates synchronously therewith. When the second switch button 66 touches the microswitch on the left, the ice-making tray 2 reaches the end point of the ice-removing stroke, and the microswitch sends a signal to the main control board, and the main control board sends a command to the motor to control the ice-making tray 2 to stop flipping. After the ice cubes fall into the ice storage drawer, the main control board drives the ice-making tray 2 to reset and rotate until the first switch button 65 touches the microswitch on the upper side. The microswitch sends a signal to the main control board, and the main control board sends a command to the motor to control the ice-making tray 2 to stop flipping, and the reset is completed.
