Description

An ice-making module with a flow guiding function Technical Field

[0001] This utility model relates to the field of ice maker technology, and specifically to an ice-making module with a flow guiding function. Background Technology

[0002] Existing water-cooled ice makers typically use an evaporator made of multiple metal sheets welded into a metal box to form square ice trays, with a water spray pipe at the top. For example, utility model patent CN221076861U discloses an ice-making device for a small ice maker. During ice making, water is sprayed from the water spray pipe, flowing sequentially from the top ice tray to the next. The refrigeration system is activated, and refrigerant flows through the evaporator pipe, lowering the evaporator temperature and gradually freezing the water flowing through the ice trays until the entire tray is filled with ice. However, this existing technology results in low ice-making efficiency. At the beginning of ice making, water only covers the lower surface of the ice trays, making it difficult for water to reach the upper back of the trays. Only after the lower half of the ice trays is covered with ice does water slowly reach the upper back until the entire tray is filled, leading to low efficiency. Sometimes, water doesn't even reach the upper back of the ice trays by the end of the process, resulting in incomplete ice and poor ice-making quality.

[0003] Therefore, there is still room for improvement and development in existing technologies. Technical solutions

[0004] To address the problems of existing technologies, this invention provides an ice-making module with a flow guiding function, which has better ice-making effect and efficiency.

[0005] To achieve the above objectives, the technical solution applied in this utility model is as follows:

[0006] An ice-making module with a flow guiding function includes an evaporator assembly with an evaporator tube and multiple ice grids; a flow guide plate fixed to the evaporator assembly, the flow guide plate having multiple through holes and multiple flow guide blocks, the through holes corresponding to the ice grids and the flow guide blocks corresponding to the through holes; and a water spray pipe fixed above the flow guide plate, the water spray pipe having multiple water spray holes corresponding to the flow guide plate. With this setup, during ice making, water is introduced from the outside into the water spray pipe and sprayed out from the spray hole. The water flows downward along the surface of the guide plate. Under the action of the guide block, the water gathers at the top of the through hole. Under the tension of the water, it flows into the ice grid and fills the entire surface of the ice grid. At this time, the refrigerant flows through the evaporator tube, the temperature of the evaporator component decreases, and the cold energy is transferred to the ice grid, causing some of the water flowing into the ice grid to freeze. The water that does not freeze flows out of the ice grid, passes through the next guide block, and flows into the next ice grid until the water flows through the bottom ice grid. This setup results in better ice making effect and efficiency.

[0007] According to the above scheme, the upper end of the guide plate is provided with multiple baffles at intervals, and a flow channel is formed between two adjacent baffles. One end of the flow channel is set corresponding to the water spray hole, and the other end of the flow channel is set corresponding to the guide block. With this configuration, when water is sprayed from the water spray hole, the water will not gather together under the action of the baffles, and the water will flow downward along the surface of the flow channel.

[0008] According to the above scheme, multiple guide blocks are spaced apart and protrude from the guide plate, with the guide blocks positioned above the through holes. With this arrangement, after water comes into contact with the guide plate, it flows downwards along the sidewalls of the guide blocks and accumulates at the top of the through holes.

[0009] According to the above scheme, a flow guide groove is formed between two adjacent flow guide blocks, and the flow guide groove is correspondingly set with the through hole. With this setting, after water comes into contact with the flow guide plate, it will flow downward along the flow guide groove and collect at the top of the through hole.

[0010] According to the above scheme, the through hole has the same shape as the inner hole of the ice tray, the through hole is tightly attached to the opening of the inner hole of the ice tray, and communicates with the inner hole of the ice tray. With this arrangement, under the surface tension of water, it flows through the inner wall of the through hole into the inner hole of the ice tray and fills the entire inner hole of the ice tray.

[0011] According to the above scheme, the lower end of the guide plate is provided with multiple drainage holes at intervals. With this arrangement, water that has not yet frozen after flowing through the bottom ice tray will flow out from the drainage holes.

[0012] According to the above scheme, multiple baffles are provided between the upper and lower ends of the guide plate, and a flow channel is formed between two adjacent baffles. One end of the flow channel is set to correspond to the water spray hole, and the other end of the flow channel is set to correspond to the guide block.

[0013] According to the above scheme, the partition is vertically arranged between two horizontally adjacent through holes, and the two horizontally adjacent through holes are spaced apart.

[0014] According to the above scheme, the upper and lower ends of the guide block are respectively provided with arc surfaces that cooperate with two vertically adjacent through holes. Beneficial effects

[0015] The beneficial effects of this utility model are:

[0016] This invention is designed such that, during ice making, water is introduced from the outside into the water spray pipe and sprayed out from the spray hole. The water flows downward along the surface of the guide plate. Under the action of the guide block, the water gathers at the top of the through hole. Under the tension of the water, it flows into the ice grid and fills the entire surface of the ice grid. At this time, the refrigerant flows through the evaporator pipe, the temperature of the evaporator assembly decreases, and the cold energy is transferred to the ice grid, causing some of the water flowing into the ice grid to freeze. The water that does not freeze flows out of the ice grid, passes through the next guide block, and flows into the next ice grid until the water flows through the bottom ice grid. This design results in better ice making effect and efficiency. Attached Figure Description

The water flows downward along the surface of the guide plate 2. Under the action of the guide block 22, the water will gather at the top of the through hole 21. Under the tension of the water, it flows into the ice grid 11 and fills the entire surface of the ice grid 11. At this time, the refrigerant flows through the evaporator pipe 12, the temperature of the evaporator assembly 1 decreases, and the cold energy is transferred to the ice grid 11, causing some of the water flowing into the ice grid 11 to freeze. The water that does not freeze flows out of the ice grid 11, passes through the next guide block 22, and flows into the next ice grid 11 until the water flows through the bottom ice grid 11.

[0026] Furthermore, the upper end of the guide plate 2 is provided with multiple baffles 23 at intervals, and a flow channel 231 is formed between two adjacent baffles 23. One end of the flow channel 231 is corresponding to the water spray hole 31, and the other end of the flow channel 231 is corresponding to the guide block 22. With this arrangement, when water is sprayed from the water spray hole 31, the water will not gather together under the action of the baffles 23, and the water will flow downward along the surface of the flow channel 231.

[0027] Furthermore, multiple guide blocks 22 are spaced apart and protrude from the guide plate 2, with the guide blocks 22 positioned above the through holes 21. With this arrangement, after water comes into contact with the guide plate 2, it flows downwards along the sidewalls of the guide blocks 22 and accumulates at the top of the through holes 21.

[0028] Furthermore, a flow channel 221 is formed between two adjacent flow guide blocks 22, and the flow channel 221 is correspondingly arranged with the through hole 21. With this arrangement, after water comes into contact with the flow guide plate 2, it will flow downward along the flow channel 221 and collect at the top of the through hole 21.

[0029] Furthermore, the through hole 21 has the same shape as the inner hole of the ice tray 11, and the through hole 21 is closely attached to the opening of the inner hole of the ice tray 11 and communicates with the inner hole of the ice tray 11. With this arrangement, under the tension of water, it flows through the inner wall of the through hole 21 into the inner hole of the ice tray 11 and fills the entire inner hole of the ice tray 11.

[0030] Furthermore, the lower end of the guide plate 2 is provided with multiple drain holes 24 at intervals. With this arrangement, water that has not yet frozen after flowing through the bottom ice tray 11 will flow out from the drain holes 24. Example

[0031] As shown in Figures 4 and 5, multiple baffles 23 are spaced apart between the upper and lower ends of the guide plate 2. A flow channel 231 is formed between two adjacent baffles 23. One end of the flow channel 231 is corresponding to the water spray hole 31, and the other end of the flow channel 231 is corresponding to the guide block 22.

[0032] Furthermore, the partition 23 is vertically disposed between two horizontally adjacent through holes 21, and the two horizontally adjacent through holes 21 are spaced apart.

[0033] Furthermore, the upper and lower ends of the flow guide block 22 are respectively provided with arc surfaces 222 that cooperate with two vertically adjacent through holes 21.

[0034] The difference between this embodiment 2 and embodiment 1 is that the structure of the flow guide block 22 and the partition 23 are slightly different. The rest of the structure and principle are the same as those in embodiment 1, and will not be repeated.
