Description

Technical Field

[0001] The utility model relates to the technical field of ice making machines, in particular to an ice cube detachment testing device. Background Art

[0002] When preparing ice cubes, the ice maker generally freezes the water injected into the ice grid to make ice cubes, and then makes the ice cubes fall out of the ice grid. The ice grid deicing methods are mainly divided into heating method and twisting method. The heating deicing method heats the surface of the ice grid to melt the surface of the ice cubes in contact with the ice grid, so as to achieve the purpose of making the ice cubes fall out. The ice grid using this deicing method is generally a metal ice grid; the twisting deicing method drives the ice grid to twist and deform, squeezes the ice cubes to achieve the purpose of making the ice cubes fall out. The ice grid using this deicing method is generally a polymer material ice grid.

[0003] For ice trays that use a twisting de-icing method, the de-icing effect is determined by the twisting angle of the ice tray. Generally, in order to completely de-iced, the twisting angle is designed to be relatively large, but this will not only cause a large plastic deformation of the ice tray, but also reduce the service life of the ice tray. Therefore, when driving the ice tray to twist, how to determine the appropriate twisting angle is an urgent problem to be solved. Utility Model Content

[0044] The following will further describe in detail the specific implementation manners of the present utility model with reference to the drawings and embodiments. The following embodiments are used to illustrate the present utility model but are not intended to limit the scope of the present utility model.

[0045] Refer to Figure 1 - Figure 16 As shown, an ice cube tray defrosting test device provided by an embodiment of the present utility model includes a base 1, a first bracket 2, a second bracket 3, an angle scale 4, and an indicating needle 5. The first bracket 2 is installed on the base 1, and a first mounting position 21 for rotatably mounting one end of the ice cube tray 9 is provided on the first bracket 2; the second bracket 3 is installed on the base 1 and is spaced apart from the first bracket 2 relatively. A second mounting position 31 for rotatably mounting the other end of the ice cube tray 9 is provided on the second bracket 3. A stop portion 32 is further provided on the surface of the second bracket 3 facing the first bracket 2; the angle scale 4 is fixed on the first bracket 2, and angle scale lines 41 are circumferentially provided on the angle scale 4; one end of the indicating needle 5 is rotatably installed on the surface of the angle scale 4 facing away from the first bracket 2 and is used to connect with the end of the ice cube tray 9 rotatably installed on the first bracket 2, and the other end points to the angle scale line 41.
