The ice dislodging unit comprises a connecting piece fixedly connected to the driving shaft, a plurality of connecting rods arranged at intervals on the connecting piece, and a plurality of ice dislodging frames arranged at the free ends of the connecting rods, respectively. The extending directions of the ice dislodging frames and the connecting rods are perpendicular to each other. The ice dislodging frames are accommodated in the ice guide groove, so that the ice dislodging frames can drive the ice blocks in the ice guide groove to flow to the ice discharging port.

[0006] Further, the driving device further comprises a heat insulating piece arranged between the storage ice bucket inner container and the driving main body.

[0007] Further, a plurality of the connecting rods are arranged in a circumferential array with the connecting piece as the center.

[0008] Further, the outer profiles of the ice dislodging frames and the connecting rods are both in an "L" shape.

[0009] Further, the ice dislodging frame comprises an ice dislodging frame main body and an ice dislodging groove arranged on one side of the ice dislodging frame main body.

The ice-dispensing device can drive the ice cubes to slide along the chute to the ice outlet. The spacing between the chute and the opening of the ice outlet is the same as the spacing between the openings of the ice outlet. It is conceivable that the chute not only guides the ice cubes to the ice outlet but also screens the ice cubes by size to prevent large ice cubes from flowing directly into the ice outlet.

[0016] The specific embodiments of the utility model are further described in detail below. It should be understood that the description of the utility model embodiments herein does not limit the protection scope of the utility model.

[0017] As Figures 1 to 3 The ice outlet device includes an ice storage bucket 10 and an ice outlet device 20 arranged on the ice storage bucket 10. The ice outlet device further includes other functional modules such as assembly components and the like, which should be the technology known to those skilled in the art, and will not be described in detail one by one.

[0018] The ice storage bucket 10 includes an ice storage bucket inner container 11 and an ice storage bucket shell 12 arranged outside the ice storage bucket inner container 11.

[0019] The ice storage bucket inner container 11 includes an inner container main body 111, an ice outlet end face 112 arranged on the inner container main body 111, an ice guide groove 113 arranged on the ice outlet end face 112, and an ice outlet 114 arranged in the ice guide groove 113.

[0020] The inner container main body 111 is composed of a plurality of side walls and a bottom wall. The inner container main body 111 and the ice outlet end face 112 are connected to each other and form a structure with a top opening, so that the ice blocks enter the ice storage bucket inner container 11 through the top opening. The connection structure between the inner container main body 111 and the ice outlet end face 112 is a prior art.

[0021] The ice outlet end face 112 is arranged obliquely, so that the ice blocks in the ice storage bucket inner container 11 flow to the side of the ice outlet end face 112, thereby facilitating the flow of ice blocks to the ice guide groove 113.

[0022] The ice guide groove 113 is a ring structure, and is used to guide the ice blocks in the ice storage bucket inner container 11 to flow to the ice outlet 114. The groove spacing of the ice guide groove 113 is the same as the opening spacing of the ice outlet 114. It can be conceived that the ice guide groove 113 can not only guide the ice blocks to flow to the ice outlet 114, but also can realize the screening of the size of the ice blocks to prevent large ice blocks from directly flowing to the ice outlet 114.

[0023] The ice outlet 114 is arranged in the ice guide groove 113. The ice outlet 114 is a passage for the ice blocks in the ice storage bucket inner container 11 to flow out. The ice outlet 114 is a prior art, and will not be described here.

[0024] The ice storage barrel shell 12 is arranged outside the ice storage barrel inner container 11, and is spaced apart from the ice storage barrel inner container 11. The ice storage barrel shell 12 is used for protecting the ice storage barrel inner container 11. The ice storage barrel shell 12 and the ice storage barrel inner container 11 are spaced apart to ensure the temperature in the ice storage barrel inner container 11. The connection structure between the ice storage barrel shell 12 and the ice storage barrel inner container 11 is a prior art, which will not be described here.

[0025] The ice discharging device 20 comprises a driving device 21 arranged between the ice storage barrel inner container 11 and the ice storage barrel shell 12, a ice pushing unit 22 arranged on the driving device 21 and accommodated in the ice storage barrel inner container 11, and a stirring frame 23 arranged on the ice pushing unit 22. The central axis of the ice discharging device 20 coincides with the central axis of the ice guide groove 113, that is, the rotation path of the ice discharging device 20 coincides with the ice guide groove 113, so as to drive the ice blocks in the ice guide groove 113 to move.

[0026] The driving device 21 comprises a driving body 211 arranged between the ice storage barrel inner container 11 and the ice storage barrel shell 12, a driving shaft 212 arranged on the driving body 211 and inserted into the ice storage barrel inner container 11, and a heat insulation member 213 arranged between the ice storage barrel inner container 11 and the driving body 211.

[0027] The driving body 211 is used for driving the driving shaft 212 to rotate. The driving shaft 212 is connected with the ice pushing unit 22, so as to drive the ice pushing unit 22 to rotate. The connection structure between the driving body 211, the driving shaft 212 and the driving body 211 and the driving shaft 212 is a prior art. The ice guide groove 113 is an annular structure. The central axis of the driving shaft 212 coincides with the central axis of the ice guide groove 113, so as to cooperate with the ice pushing unit 22.

[0028] The heat insulation member 213 is arranged between the ice storage barrel inner container 11 and the driving body 211. The heat insulation member 213 separates the driving body 211 from the ice storage barrel inner container 11, so as to prevent the temperature on the driving body 211 from being transmitted to the ice storage barrel inner container 11. In this embodiment, the heat insulation member 213 is a flange. The flange connects the ice storage barrel inner container 11 and the driving body 211 together, so as to stabilize the position of the driving body 211 on the side of the ice storage barrel inner container 11. The flange prevents the temperature on the driving body 211 from being transmitted to the ice storage barrel inner container 11 by the thickness of the flange. The heat insulation member 213 is a prior art, which will not be described here.

[0029] The ice-pushing unit 22 comprises a connecting member 221 fixedly connected to the driving shaft 212, a plurality of connecting rods 222 arranged at intervals on the connecting member 221, and a plurality of ice-pushing frames 223 respectively arranged at free ends of the connecting rods 222.

[0030] The connecting member 221 is used to connect the driving shaft 212, i.e. to realize the connection between the ice-pushing unit 22 and the driving shaft 212. In this embodiment, the connecting member 221 is a mounting sleeve which is sleeved on the driving shaft 212, and the mounting sleeve and the driving shaft 212 can be connected by any one of welding, screwing and riveting to realize the fixed connection between the mounting sleeve and the driving shaft 212.

[0031] The connecting rods 222 are used to connect the ice-pushing frames 223 and the connecting member 221 together. The connecting rods 222 are arranged in a circular array with the connecting member 221 as the center, i.e. the gaps between the connecting rods 222 are all the same, so that the connecting member 221 uniformly drives the ice blocks in the inner container 11 of the ice storage bucket.

[0032] The outer profiles of the ice-pushing frames 223 and the connecting rods 222 are both in the shape of “L”. The “L” shape makes the ice-pushing frames 223 and the connecting rods 222 have higher stability and carrying capacity, and the “L” shape structure also facilitates the ice-pushing frames 223 and the connecting rods 222 to drive the ice blocks to move. Moreover, the extension directions of the ice-pushing frames 223 and the connecting rods 222 are perpendicular to each other, i.e. the ice-pushing frames 223 and the connecting rods 222 respectively drive the ice blocks in the ice storage bucket 10 to move in different directions.

[0033] The ice-pushing frames 223 are accommodated in the ice guide groove 113. When the driving device 21 drives the ice-pushing unit 22 to rotate, the ice-pushing frames 223 slide along the ice guide groove 113, and the ice-pushing frames 223 can drive the ice blocks in the ice guide groove 113 to flow to the ice outlet 114.

[0034] The ice-pushing frame 223 comprises an ice-pushing frame body 2231 and an ice-pushing groove 2232 arranged on one side of the ice-pushing frame body 2231. The outer profile of the ice-pushing groove 2232 is in the shape of a wedge, wherein the wide end of the ice-pushing groove 2232 faces the ice guide groove 113. It is conceivable that the narrow end of the ice-pushing groove 2232 faces away from the ice guide groove 113, so as to prevent the ice blocks in the ice guide groove 113 from flowing out of the ice guide groove 113 along the ice-pushing groove 2232.

[0035] The outer contour of the stirring frame 23 is inverted "U" type, the stirring frame 23 is fixed on the connecting rod 222, and the ice-pushing unit 22 coincides with the central axis of the stirring frame 23. When the driving device 21 drives the ice-pushing unit 22 to rotate, the stirring frame 23 also rotates synchronously, and the ice in the ice storage barrel inner container 11 is hit by the stirring frame 23 to separate the large ice blocks into small ice blocks. The connection structure between the stirring frame 23 and the connecting rod 222 is a prior art, which will not be described here.

[0036] Compared with the prior art, the automatic ice discharging device for the ice maker can screen the ice blocks in the ice storage barrel inner container 11 of the ice storage barrel 10 and transmit the ice blocks in the ice storage barrel 10 to the ice discharging port 114. The ice discharging end surface 112 in the ice storage barrel inner container 11 is provided with an ice guide groove 113, and the ice discharging port 114 is arranged in the ice guide groove 113. The ice guide groove 113 is an annular structure, the central axis of the ice discharging device 20 coincides with the central axis of the ice guide groove 113, that is, the rotation path of the ice discharging device 20 coincides with the ice guide groove 113, and the ice discharging device 20 can drive the ice blocks to slide along the ice guide groove 113 to the ice discharging port 114. The groove spacing of the ice guide groove 113 is the same as the opening spacing of the ice discharging port 114. It is conceivable that the ice guide groove 113 can not only guide the ice blocks to flow to the ice discharging port 114, but also can screen the size of the ice blocks to prevent large ice blocks from directly flowing to the ice discharging port 114. The driving device 21 in the ice discharging device 20 drives the ice pushing unit 22 and the stirring frame 23 to rotate. The connecting piece 221 in the ice pushing unit 22 is connected with the driving shaft 212 in the driving device 21, the connecting rod 222 is arranged on the connecting piece 221, the ice pushing frame 223 is arranged at the free end of the connecting rod 222, the ice pushing frame 223 is accommodated in the ice guide groove 113, and when the driving device 21 drives the ice pushing unit 22 to rotate, the ice pushing frame 223 slides along the ice guide groove 113. The ice pushing frame 223 can drive the ice blocks in the ice guide groove 113 to flow to the ice discharging port 114. The extension directions of the ice pushing frame 223 and the connecting rod 222 are perpendicular to each other, so that the ice pushing frame 223 and the connecting rod 222 respectively drive the ice blocks in the ice storage barrel 10 to move in different directions. The ice pushing frame 223 is accommodated in the ice guide groove 113, and when the driving device 21 drives the ice pushing unit 22 to rotate, the ice pushing frame 223 slides along the ice guide groove 113. The ice pushing frame 223 can drive the ice blocks in the ice guide groove 113 to flow to the ice discharging port 114. Moreover, the stirring frame 23 is arranged on the connecting rod 222, and when the driving device 21 drives the ice pushing unit 22 to rotate, the stirring frame 23 also rotates synchronously. The stirring frame 23 strikes the ice blocks in the ice storage barrel inner container 11, so that large ice blocks are separated into small ice blocks. It can be seen that the ice discharging device realizes the screening and stirring of the ice blocks, improves the ice discharging stability and efficiency.
