When ice removing is needed, the first driving assembly 40 drives the water storage box 21 to rotate to the ice removing position, and the water in the water storage box 21 is poured out and flows to the ice guide plate 54 under the action of gravity. Since the ice guide plate 54 is provided with the water leakage hole 55, the water flows into the water receiving box 52. By reversely inputting current to the semiconductor refrigeration device 30, the semiconductor refrigeration device 30 transfers heat to the ice making column 11, and the heat is conducted to the ice making column 11 to realize heating ice removing, and the ice blocks slide along the ice guide plate 54 to the ice receiving box 53.

[0056] The shape of the water storage box 21 can be set according to actual needs, such as a cuboid, a semi-cylinder or a semi-elliptical cylinder. In the embodiment, the water storage box 21 is in a semi-cylinder shape, facilitating water flow out of the water storage box 21. When the water storage box 21 is in the ice making position, the opening of the water storage cavity 211 faces upward, and when the first driving assembly 40 drives the water storage box 21 to rotate to the ice removing position, the opening of the water storage cavity 211 faces one side or is inclined downward.

Preferably, the rotation speed angle of the water storage box 21 from the ice making position to the ice removing position is between 90° and 120°.

[0057] In the embodiment, the water storage box 21 is rotationally connected with the shell 51. In other embodiments, the water storage box 21 is rotationally arranged on a support in the shell 51. Illustratively, both ends of the water storage box 21 are provided with rotation shafts 212, one rotation shaft 212 is rotationally connected with the shell 51, and the other rotation shaft 212 is connected with the first driving assembly 40. In some embodiments, the first driving assembly 40 includes a motor, the motor is connected with the rotation shaft 212 to drive the water storage box 21 to rotate.

[0059] The semiconductor refrigeration piece 30 is provided with a heat sink 60 away from one side of the ice making plate 12, the heat sink 60 takes away the heat of the semiconductor refrigeration piece 30, and realizes the ice making process. The ice making plate 12 and the heat sink 60 can be locked by a locking piece to fix the semiconductor refrigeration piece 30. Exemplarily, the locking piece uses the existing bolt. Alternatively, the semiconductor refrigeration piece 30 includes a plurality of semiconductor refrigeration pieces, the semiconductor refrigeration pieces have oppositely arranged first and second sides, the first side is attached to the heat sink 60, and the second side is attached to the ice making plate 12. Under different power-on states, one of the first and second sides is a hot end and the other is a cold end.

When deicing, the second side is a hot end to transfer heat to the ice making plate 12 and the ice column 11 to facilitate deicing, and the first side is a cold end to take away cold by the heat sink 60.

[0060] The heat sink 60 is flat and attached to the semiconductor refrigeration piece 30 to increase the contact area of the heat sink 60 and the semiconductor refrigeration piece 30 and improve the heat dissipation efficiency. The heat sink 60 is cooled by water, and has a water inlet 61 and a water outlet 62. In a conventional arrangement, a circulating pump is used to drive the water flow into the heat sink 60 from the water inlet 61 and out of the heat sink 60 from the water outlet 62, and the water flow out of the water outlet 62 is driven by the circulating pump to enter the heat sink 60 from the water inlet 61, realizing water circulation. Because the water flow is circulated, the heated water is used multiple times, and the heat dissipation effect is reduced.

[0061] In the present embodiment, the ice making device further includes a second water supply assembly 70, the inside of the heat sink 60 forms a water flow channel, and the second water supply assembly 70 can continuously guide the water flow to pass through the water flow channel and be discharged in a single pass. The water flow passes through the water flow channel in a single pass and is not recycled, that is, the water flow enters the heat sink 60 from the water inlet 61 and flows out of the heat sink 60 from the water outlet 62, and the water flow out of the water outlet 62 will not enter the heat sink 60 from the water inlet 61. The water flow is not circulated, and after flowing through the heat sink 60, it is directly discharged, and a sufficient water source is needed to continuously supply water to the water inlet 61. During the process of the water flow passing through the water flow channel, the water flow takes away heat so that the heated water is discharged, ensuring the heat dissipation effect.

[0062] Exemplarily, the second water supply assembly 70 comprises a water inlet valve and a water outlet valve, the water inlet valve is arranged upstream of the water inlet 61, and the water outlet valve is arranged downstream of the water outlet 62.

When heat dissipation is needed, the second water pump 71 is started to guide the water flow into the radiator 60 along the second water supply pipe 72.

[0063] The water flow channel in the radiator 60 is bent to extend, so as to increase the heat dissipation area. Exemplarily, the water flow channel extends in an S shape, or the water flow channel extends in a reciprocating bending manner. In the embodiment, the radiator 60 comprises a first cover plate 63 and a second cover plate 64 which are detachably connected, the first cover plate 63 and the second cover plate 64 enclose a heat dissipation cavity, a plurality of heat conduction fins 65 are arranged in the heat dissipation cavity in a spaced manner, and the plurality of heat conduction fins 65 enclose the reciprocating bending water flow channel. Through the detachable connection manner, the radiator 60 is convenient to install, disassemble and maintain.

[0064] Optionally, as shown in Figure 10 , the plurality of heat conduction fins 65 are arranged in parallel and in a spaced manner in the heat dissipation cavity, one end of the heat conduction fin 65 is sealingly connected with the inner wall of the heat dissipation cavity, the other end of the heat conduction fin 65 is arranged in a spaced manner with the inner wall of the heat dissipation cavity to form a flow guide opening 67, and a plurality of flow guide openings 67 are arranged in an alternating manner on opposite sides of the heat dissipation cavity. The water flow entering from the water inlet 61 can flow along the heat conduction fin 65 to the flow guide opening 67, so as to flow through the two sides of each heat conduction fin 65 in sequence and flow out from the water outlet 62. The more the number of heat conduction fins 65 arranged, the more tortuous the water flow channel is, so as to prolong the residence time of the water flow in the water flow channel and improve the heat exchange efficiency.

[0065] Optionally, as shown in Figure 11 , the plurality of heat conduction fins 65 are arranged in parallel and in a spaced manner in the heat dissipation cavity, one end of the heat conduction fin 65 is sealingly connected with the inner wall of the heat dissipation cavity to form a flow guide fin 651, the other end of the flow guide fin 651 is arranged in a spaced manner with the inner wall of the heat dissipation cavity to form a flow guide opening 67, a plurality of flow guide openings 67 are arranged in an alternating manner on opposite sides of the heat dissipation cavity, both ends of part of the heat conduction fins 65 are arranged in a spaced manner with the inner wall of the heat dissipation cavity to form a flow distribution fin 652, and the flow distribution fin 652 is arranged between two adjacent flow guide fins 651. By arranging the flow distribution fin 652, the water flow is divided into at least two routes when flowing between adjacent flow guide openings 67, the contact between the water flow and the flow distribution fin 652 increases the heat exchange area, and the heat exchange efficiency is improved.

[0066] The first cover plate 63 and the second cover plate 64 can be locked by a locking member. Exemplarily, the locking member is a bolt. A sealing ring 66 is arranged between the first cover plate 63 and the second cover plate 64 to ensure the sealing of the heat dissipation cavity. Exemplarily, the second cover plate 64 is provided with a mounting groove, and the sealing ring 66 is inserted into the mounting groove and abuts against the first cover plate 63.

Exemplarily, the second cover plate 64 is made of plastic to reduce the weight.

[0068] The heat sink 60 can also be assisted by a fan to dissipate heat. In other embodiments, the heat sink 60 can be a heat pipe type heat sink.
