It should be noted that the specific connection method of the heat exchange cylinder 11 is not limited here. For example, please refer to Figure 12. The heat exchange cylinder 11 is connected to the ice forming plate 50. Since the heat exchange cylinder 11 is arranged in the manufacturing In the ice cavity 20a, in order to prevent the heat exchange cylinder 11 from interfering when the ice scraping assembly 20 rotates, the heat exchange cylinder 11 is connected to the ice forming plate. Specifically, the ice forming plate 50 and the heat exchange cylinder 11 are coaxially arranged. , the top of the heat exchange cylinder 11 extends toward the ice forming plate 50 to form a ring-shaped mounting portion 111 , and is tightly connected to the ice forming plate 50 through the mounting portion 111 .

The ice sweeping rod 60 is connected to the screw rod 211, that is to say, the ice sweeping rod 60 can rotate together with the screw rod 211, so as to promptly break the ice formed and extruded through the ice forming hole 50a of the ice forming plate 50.

The ice sweeping rod 60 is spaced apart from the top surface of the ice forming plate 50, and the height of the space is the height of ice cubes.

In one embodiment, please refer to Figures 1 to 3 and 12. The ice making module includes a top cover 70, an ice baffle 80 and an ice outlet baffle 90. The top cover 70 is disposed above the ice forming plate 50 to prevent ice cubes from forming. Scattered out, the ice outlet baffle 90 and the top cover 70 define the ice outlet direction. The ice baffle 80 is 600~5mm higher than the ice sweeping rod to prevent the two from being squeezed. At the same time, the ice baffle 80 and the ice outlet baffle 90 There is a certain angle between them to prevent the ice cubes from flowing back to the ice forming plate 50 during the de-icing process.

In one embodiment, please refer to Figures 2 and 3, the ice sweeping rod 60 includes two ice sweeping columns 61 perpendicular to the ice forming plate 50, used to control the ice forming width, while sweeping and pushing or carrying other top covers 70. of ice storage.

The deicing process is as follows: the ice sweeping rod 60 is connected to the screw rod 211, so it rotates synchronously with the screw rod 211. The crushed ice carried by the screw rod 211 is continuously squeezed and formed in the ice forming plate 50. It is extruded to achieve continuous ice making, and is finally broken into ice cubes by the rotation of the ice sweeping rod 60. The height of the ice sweeping rod 60 is the height of the generated ice cubes. The broken ice blocks continue to accumulate in the top cover 70. Finally, when the accumulated ice is higher than the ice sweeping rod 60 and lower than the ice blocking plate, through the relative movement of the ice sweeping rod 60 and the ice blocking plate 80, the ice finally moves along the ice blocking plate. The wall surface of the ice baffle 80 is pushed out of the top cover 70 and falls into the ice storage box (not shown).

Referring to Figures 10 and 11, the heat exchange unit 10 includes a refrigerant inlet pipe 12 and a refrigerant outlet pipe 13. The refrigerant enters the heat exchange unit 10 through the refrigerant outlet pipe 13, and flows out of the heat exchange unit 10 through the refrigerant outlet pipe 13, thereby realizing the refrigerant circular flow.

The outlet of the refrigerant inlet pipe 12 is located at the bottom of the refrigerant accommodating cavity 10a, and the inlet of the refrigerant outlet pipe 13 is located at the top of the refrigerant accommodating cavity 10a. In this way, the interior of the heat exchange unit 10 can be filled with refrigerant. In addition, it can also be made to meet the requirements of heat separation. The layer effect, where lower temperature refrigerant is at the bottom and higher temperature is at the top, increases ice making speed.

In order to prevent the ice on the surface of the heat exchange unit 10 from being too thick to be scraped off, thus reducing the thermal conductivity, it is necessary to control the distance between the first ice scraper 21 and the heat exchange unit 10. For example, the first The distance between the ice scraper 21 and the heat exchange unit 10 is 0.2 mm to 1 mm. This prevents the first ice scraper 21 from being too thick on the surface of the heat exchange unit 10 to be scraped off the surface. Interference occurs with the heat exchange unit 10 .

In one embodiment, the distance between the second ice scraper 22 and the heat exchange unit 10 is 0.2 mm to 1 mm. This prevents ice from being too thick on the surface of the heat exchange unit 10 and preventing it from being scraped off the surface. Interference between the second ice scraper 22 and the heat exchange unit 10 is prevented.

It can be understood that the distance between the first ice scraper 21 and the second ice scraper 22 and the heat exchange unit 10 may be the same or different, and may be determined according to the actual situation.
