For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0024] Refer to the following Figure 1-4 An evaporator for ice making according to some embodiments of the present application is described.

[0025] An evaporator for ice making includes an upper cover plate 1 and a lower cover plate 2. The middle part of the upper cover plate 1 and the lower cover plate 2 is an ice making area 3. A plurality of ice cube grooves 4 are arranged in the ice making area 3. The outer area of ​​the upper cover plate 1 and the lower cover plate 2 surrounding the ice making area 3 is a welding area 5 for welding the upper cover plate 1 and the lower cover plate 2. The ice making area 3 of the upper cover plate 1 and the lower cover plate 2 is provided with an air avoidance structure. When the upper cover plate 1 and the lower cover plate 2 are welded, a first cavity 6 is formed between the upper cover plate 1 and the lower cover plate 2. The first cavity 6 is provided with tapered openings 7 at both ends of the upper cover plate 1 and the lower cover plate 2 in the length direction. The tapered opening 7 connects the first cavity 6 with the refrigerant pipeline of the refrigeration device.

[0026] After water is added into the ice cube groove 4, the refrigerant of the refrigeration device enters the first cavity 6 through the pipeline via the tapered opening 7, and continuously freezes the ice cube groove 4 so that the water in the ice cube groove 4 is frozen into ice cubes.

[0027] In one embodiment, Figure 2As shown, the air avoidance structure is a boss 8 provided on the upper cover plate 1, and the ice-making area 3 of the upper cover plate 1 is located on the boss 8. Therefore, after the upper cover plate 1 and the lower cover plate 2 are welded, due to the lifting height of the boss 8, a gap is formed between the ice-making area 3 in the middle after the upper cover plate 1 and the lower cover plate 2 are welded, thereby forming a first cavity 6.

[0028] In another embodiment, the air avoidance structure is a groove provided on the lower cover plate 2, and the ice making area 3 of the lower cover plate 2 is located in the groove. Therefore, after the upper cover plate 1 and the lower cover plate 2 are welded, due to the sinking of the groove, a gap is formed between the ice making area 3 in the middle after the upper cover plate 1 and the lower cover plate 2 are welded, and the first cavity 6 can also be formed.

[0029] A through hole 9 is provided in the welding area 5 corresponding to the tapered opening 7, and a joint of the refrigerant pipeline is welded in the through hole 9.

[0030] A water guide groove 10 is provided between adjacent ice cube grooves 4 to facilitate the water level in each groove to be level when water is poured into the ice cube groove 4 .

[0031] The ice cube groove 4 is at least one of a rectangle, a semicircle, an inverted triangle or an inverted trapezoid with a top opening, so that the ice cubes can be easily removed from the ice cube groove 4 after being frozen.

[0032] The upper cover plate 1 and the lower cover plate 2 are formed by stamping and stretching of food-grade metal plates, which are easy to manufacture and process. In addition, the evaporator has a simple structure and is easy to install and use in refrigerators and wine cabinets.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
