Description

Technical Field

[0002] Currently, ice makers are used to make ice cubes. They are equipped with a refrigeration system, which includes an evaporator. For example, Chinese Utility Model Patent Publication No. CN219868632U, titled "An Ice Maker," describes an ice maker with a sleeve-shaped evaporator that surrounds the outside of an ice-making cylinder. An ice extruder (screw) is located inside the ice-making cylinder. Another example is Chinese Utility Model Patent Publication No. CN218410348U, titled "An Evaporator for an Ice Maker and an Ice Maker." In this evaporator, the inner cavity is connected to a refrigerant inlet pipe and an outlet pipe. A gas-liquid mixture of refrigerant is introduced into the evaporator's inner cavity through the inlet pipe. The refrigerant evaporates and absorbs heat within the evaporator's inner cavity, and then the gaseous refrigerant is output through the outlet pipe. However, the refrigerant flow and distribution within the inner cavity is uneven, creating a significant weak cooling zone, resulting in low ice-making efficiency. Therefore, the aforementioned sleeve-shaped evaporator needs improvement. Summary of the Invention

[0017] The working principle of the evaporator of the utility model is briefly described as follows: the refrigerant in gas-liquid mixed state is input into the spray pipe 8 through the input pipe 5, and the lower end of the spray pipe 8 is closed, so that the refrigerant in gas-liquid mixed state is sprayed onto the outer wall of the inner cylinder 2 along the radial direction of the inner cylinder 2 through each spray hole 801, as shown in the figure. Figure 3 As shown in the figure, the top ring cover 3 is provided with an input pipe 5 and an output pipe 6, the input pipe 5 and the output pipe 6 are arranged on the opposite sides, and the lower end of the output pipe 6 is inserted into the air outlet hole formed in the left end of the top ring cover 3, and the outer wall of the output pipe 6 is sealingly welded with the edge of the air outlet hole, the right end of the top ring cover 3 is formed with a liquid inlet hole, and the lower end of the input pipe 5 passes through the liquid inlet hole. Figure 3As shown, but because the cross partition 101 is arranged at the lower side of the corresponding spray hole 801, so that the downward flowing refrigerant is intercepted and guided by the cross partition 101 to maintain horizontal flow for a long time, and because the refrigerant vaporization speed is fast, so that the refrigerant can be avoided to concentrate and sink to the lower part of the evaporating cavity 10, further beneficial to the uniformity of the refrigeration effect of the evaporator. From the foregoing, the evaporator of the utility model can avoid forming an obvious weak refrigeration area, and the evaporator of the utility model is beneficial to improve the ice making efficiency. Because the spray hole 801 is directly sprayed to the outer wall of the inner cylinder 2, so that the refrigerant can directly exchange heat with the inner cylinder 2, so that the cooling effect of the ice making cylinder arranged in the inner cylinder 2 is better. The refrigerant is specifically arc flow around the outer wall of the inner cylinder 2 to the lower end of the output pipe 6 (flows through the evaporating cavity 10).

[0018] Further, as shown in the drawings, Figure 3 The two ends of the cross partition 101 are formed with an upward portion 1011 respectively, when the refrigerant is sprayed on the outer wall of the inner cylinder 2, the refrigerant flows in the left and right directions after being dispersed, and the upward portion 1011 is guided to flow obliquely upward to leave the upward portion 1011, so that the liquid refrigerant can obtain a throwing effect, which can further reduce the refrigerant sinking condition, and is beneficial to the uniformity of the refrigeration effect of the evaporator.

[0019] Further, as shown in the drawings, Figure 2 As shown in the drawings, Figure 2 Only one of the two blocking sheets 102 close to the observer is drawn, the blocking sheet 102 is vertically arranged, and the two blocking sheets 102 are arranged on the two sides of the lower end of the output pipe 6 in the circumferential direction of the inner cylinder 2, and the lower end of the output pipe 6 is higher than the blocking sheet 102, because the negative pressure of the lower end of the output pipe 6 is large, by arranging the blocking sheet 102 to locally block the refrigerant flow through the upper part of the outer wall of the inner cylinder 2, the suction strength of the refrigerant at the bottom position of the evaporating cavity 10 directly below the output pipe 6 can be relatively increased, and the refrigerant flow dead zone can be avoided, thereby improving the refrigeration effect of the evaporator.
