一种具有排水功能的制冰蒸发器及其制冰机

Abstract

本实用新型公开的一种具有排水功能的制冰蒸发器及其制冰机，包括蒸发铜管和制冰格，蒸发铜管和制冰格由铝合金压铸制成一体成型的结构；制冰格后侧凸出设置有沿蒸发铜管的延伸方向、将蒸发铜管埋设安装于每个制冰格的内腔对应侧的S形凸出部；制冰格上每个冰块成型腔的内腔底部还贯通开设有防止内腔底部冰块脱模负压吸附的负压脱模孔，沿S形凸出部形成将所有负压脱模孔流出融水汇流、用于制冰时冰块脱模时融水排出的排水流道；通过在蒸发器的背面形成与前侧面连通的排水流道，在出冰时同步排出后侧空腔融水，提高蒸发器后续循环制冰的效率，能够有效将缝隙渗入的水进行排放，提高制冰的质量，减少细菌滋生。

Claims

1. An ice-making evaporator having a drainage function, characterized by, It includes an evaporating copper tube and an ice-making grid. The front side of the ice-making grid is provided with multiple arrayed ice-forming cavities. The evaporating copper tube is connected to the ice-making refrigeration system. The evaporation copper tube and ice grid are integrally formed by die casting of aluminum alloy. The evaporation copper tubes are cyclically bent and folded relative to each ice block forming cavity in the ice grid to form a curved channel that is symmetrically distributed in an S-shape with the length direction as the center and directly exchanges cold energy with each ice block forming cavity of the ice grid. The ice tray has an S-shaped protrusion on its rear side, which extends along the extension direction of the evaporating copper tube and is integrally die-cast with the ice tray, with the evaporating copper tube embedded in the corresponding side of the inner cavity of each ice tray. The bottom of the inner cavity of each ice block forming cavity on the ice grid is also provided with a negative pressure demolding hole for quick demolding of ice blocks in the cavity and to prevent negative pressure adsorption at the bottom of the inner cavity. The S-shaped protrusion along the extension direction of the evaporation copper tube forms a drainage channel for the melt water flowing out of all the negative pressure demolding holes and for the melt water to be discharged when the ice blocks are demolded during ice making. The ice grid is symmetrical about the length of the ice grid. A converging channel is recessed on the rear end face of the ice grid to collect and gather meltwater in the drainage channel. The converging channel is provided with a plurality of drainage holes that are connected to the front end face of the ice grid and are used to drain water accumulated in the rear cavity corresponding to the rear side when the ice is dispensed.

2. The ice-making evaporator having a drainage function according to claim 1, wherein: On the other side of the ice outlet of the ice grid, the bottom surfaces of all adjacent ice forming cavities are flush and integrally die-cast, and the S-shaped protrusion and the evaporation copper tube protrude from the outer side of the bottom surface of all the ice grids.

3. The ice-making evaporator having a drainage function according to claim 1, wherein: The evaporation copper tubes are connected in an S-shaped loop, and are directly aligned with the upper and lower sides and part of the left and right sides of the rear side of each ice block forming cavity on the ice grid.

4. The ice-making evaporator having a drainage function according to claim 1, wherein: The outlet end of the confluence channel corresponding to the edge of the ice grid is also provided with a drain outlet to facilitate the discharge of water from the front end of the ice grid.

5. The ice-making evaporator having a drainage function according to claim 1, wherein: The outer surface of the ice grid is also coated with a food-grade Teflon protective layer.

6. The ice-making evaporator having a drainage function according to claim 1, wherein: The outer side of the ice tray is also fitted with a partition cover made of silicone or plastic material that is integrally molded to prevent the ice-making water from directly contacting the ice tray and being frozen into ice by the ice tray, thus preventing ice blocks from sticking together. The partition cover has an ice outlet corresponding to each ice block forming cavity on the ice tray.

7. The ice-making evaporator having a drainage function according to claim 6, wherein: The outer end faces of the ice-forming cavities arrayed on the ice grid are flush with each other, and the inner side of the partition cover corresponding to the ice outlet is flush with and fitted to the spacing surface between the ice-forming cavities.

8. The ice-making evaporator having a drainage function according to claim 6, wherein: The back of the ice tray is also sealed with a back cover made of silicone or plastic material that is integrally molded to insulate heat conduction. This back cover is connected to the partition cover on the front to form a closed cavity to enclose the entire ice tray's cooling source and prevent the cooling energy from dissipating.

9. The ice-making evaporator having a drainage function according to claim 6, wherein: The rear side of the partition cover also has a plurality of pins that are installed in the gap between adjacent ice block forming cavities on the ice grid. The gap between adjacent ice block forming cavities is provided with positioning holes that cooperate with each positioning pin and drainage holes that communicate with drainage holes in the confluence channel on the ice grid.

10. An ice maker comprising a housing, characterized in that, The ice maker evaporator with the drainage function is installed at the ice making position of the shell. The ice maker evaporator with the drainage function is installed at the ice making position of the shell.
