Detailed Description

The present application is described in further detail below with reference to figures 2-8.

The embodiment of the application discloses a hidden ice machine. Referring to fig. 2, the hidden type ice maker includes a case 1, an ice making device 2, and an ice screening device 3. Wherein the case 1 is used to store purified water and ice cubes. The ice making device 2 is used for making pure water into ice blocks and gradually transferring the ice blocks to the ice screening device 3, and the ice screening device 3 is used for screening and draining the ice blocks.

In the present application, the ice making device 2 is composed of a conventional evaporator, a condenser, a compressor, and an electromagnetic valve and a pipeline, and will not be described below.

When ice making is needed, an operator can firstly add pure water into the ice making chamber 13, then turn on the ice making device 2, the ice making device 2 can convert the pure water into ice blocks and finally transfer the ice blocks to the ice block screening device 3, and the ice block screening device 3 screens the ice blocks and the pure water. Thereafter, the cover door 16 is controlled to open the ice discharge hole 15, and at this time, the ice cubes are gradually discharged through the ice discharge hole 15 by a small amount. When it is desired to clean the interior of the dispensing chamber 14, the operator may directly rotate the flip 12, thereby facilitating easier cleaning of the dispensing chamber 14.

In the first embodiment of the present application, the ice sieving device 3 is a filter ice box 31, and when the ice making device 2 transfers the ice to the filter ice box 31, the filter ice box 31 can directly separate the ice from the purified water and then discharge the ice through the ice outlet 15. However, it is easy to see that, once the diameter of the ice outlet 15 is small, a plurality of ice cubes are easily piled up at the ice outlet 15, thereby causing difficulty in smoothly dropping ice cubes from the ice outlet 15; however, when the diameter of the ice outlet 15 is large, a large amount of ice drops directly from the ice outlet 15, and it is difficult for the operator to control the range of the amount of ice.

Referring to fig. 3 and 4, therefore, in a second embodiment of the present application, ice screening device 3 includes a drive member 32 fixedly attached to the bottom of the dispensing chamber 14 and a screening disc 33 fixedly attached to the drive end of drive member 32, with the outer peripheral surface of screening disc 33 always abutting the walls of the dispensing chamber 14.
