[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-17 This invention provides a technical solution for an ice-making module and an ice maker.

[0020] An ice-making module includes an evaporator housing 4, a cavity 5 inside the evaporator housing 4, an ice-making mold 1 fixed on the evaporator housing 4 and inserted into the cavity 5, an ice-making groove 2 on the ice-making mold 1, the ice-making mold 1 separating the cavity 5 and the ice-making groove 2, and a refrigerant inlet 6 and a refrigerant outlet 7 communicating with the cavity 5 on the side wall of the evaporator housing 4.

[0021] The refrigerant enters the cavity 5 from the refrigerant inlet 6, at this time the ice making mold 1 is immersed in the refrigerant, the refrigerant is in full contact with the contact outer surface 3 of the ice making mold 1 and then is discharged from the refrigerant outlet 7, the refrigerant can cool the ice making mold 1, so that the water in the ice making inner groove 2 becomes ice. When the ice needs to be removed, the ice making mold 1 is warmed by increasing the temperature of the refrigerant, so that the ice block is separated from the ice making mold 1. Because the contact outer surface 3 of the ice making mold 1 can be in full contact with the refrigerant, the contact area between the ice making mold 1 and the refrigerant is increased, and the ice making efficiency is high. Because the cavity 5 on the evaporator shell 4 is a whole cavity, the structure is simple and the processing is convenient.

[0022] It should be noted that the ice making mold 1 can be arranged in one row (as shown in Figure 2 ), and can also be arranged in multiple rows, so that more ice blocks can be made at one time. The above figure only shows the structure when the opening of the ice making inner groove 2 is square, and the ice making inner groove 2 can also be arranged in other shapes such as square, polygon or semicircle, so as to realize more shapes of ice making. Of course, the ice making mold 1 can also be detachably connected with the evaporator shell 4, and the ice making mold 1 can be replaced.

[0023] The ice making mold 1 and the evaporator shell 4 can be arranged separately, processed separately, and then fixed together; of course, the ice making mold 1 and the evaporator shell 4 can also be integrally formed. Of course, the ice making mold 1 and the evaporator shell 4 can also be detachably connected, and the ice making mold 1 with different shapes of ice making inner grooves 2 can be replaced.

[0024] As shown in Figure 3 , it is a structure of the ice making inner groove 2, which is composed of a groove side wall 8 and a groove bottom 9, the groove side wall 8 is arranged obliquely, and the opening of the end of the groove side wall 8 away from the groove bottom 9 is larger than the opening of the end close to the groove bottom 9. Because the groove side wall 8 is arranged obliquely, the ice block can be easily removed from the ice making inner groove 2.

[0025] The following scheme adopts a water flow method to supply water to the ice making inner groove 2, as shown in Figures 5-9 , the angle between the evaporator shell 4 and the vertical plane is A, 20°≥A≥0°, that is, the opening of the ice making inner groove 2 is horizontal or inclined downward, so that the ice block can be easily discharged from the ice making inner groove 2 after the ice making is completed, and the upper part of the evaporator shell 4 is provided with a water supply device and a flow distribution component, the water flowing out of the water supply device flows through each ice making inner groove 2 through the flow distribution component.

[0026] As shown in Figure 7As shown, the water supply device comprises a first water supply pipe 10 fixed above the evaporator shell 4 by a first support 11, the first water supply pipe 10 is provided with a first water supply hole 12 corresponding to the ice making inner groove 2, the water distribution assembly is a recess 13 formed on the side of the evaporator shell 4 facing the first water supply hole 12, each recess 13 corresponds to at least one first water supply hole 12, and the recess 13 allows the water flowing out of the first water supply hole 12 to enter the corresponding ice making inner groove 2.

[0027] Of course, each recess 13 can correspond to multiple first water supply holes 12, that is, the water outlet pipe is provided with 30 small holes, and every 5 first water supply holes 12 correspond to one recess 13 and one ice making inner groove 2, and the 5 first water supply holes 12 supply water to one recess 13 and one ice making inner groove 2 at the same time.

[0028] Water is introduced into the water supply pipe, and then the water is discharged from the water supply hole. The discharged water enters the ice making inner groove 2 through the recess 13. The recess 13 allows the water flowing out of the water supply hole to enter each ice making inner groove 2, rather than flowing directly in front of the opening of the ice making inner groove 2. Part of the water forms a layer of ice in the ice making inner groove 2, and part of the water flows out of the ice making inner groove 2. The ice in the ice making inner groove 2 thickens layer by layer, and finally forms a whole ice block.

[0029] As shown in Figure 5 and Figure 7 , the recess 13 comprises an entry end 24 and an output end 25, the entry end 24 is arranged near the water supply hole, and the output end 25 is arranged near the ice making inner groove 2. The opening of the entry end 24 is smaller than that of the output end 25.

[0030] As shown in Figure 6 , the refrigerant inlet 6 is lower than the refrigerant outlet 7, and the refrigerant outlet 7 is arranged near the upper end of the cavity 5, so that the refrigerant can fill the entire cavity 5 when flowing, thereby improving the uniformity during ice making.

[0031] As shown in Figure 5 and Figure 7 , the water flowing out of the opening of the ice making inner groove 2 passes through the flow-through outer surface of the evaporator shell 4, which is a difficult-to-ice-removal area 29. The flow-through outer surface is located below the opening of the ice making inner groove 2. The inner wall of the evaporator shell 4 is provided with a heating cavity 30 arranged inside the flow-through outer surface. The heating cavity 30 is fixed with a heating pipe 31. The heating pipe 31 comprises a pipe inlet 32 and a pipe outlet 33. The pipe inlet 32 is connected to a heating medium. The temperature of the heating medium is higher than 0 degrees. The heating pipe 31 can prevent the water from freezing at the difficult-to-ice-removal area 29. When the mold is provided with multiple rows, the upper and lower adjacent ice blocks can be prevented from being adhered.

[0032] The pipe inlet 32 is communicated with the refrigerant outlet 7. It should be noted that the low-temperature refrigerant is introduced into the cavity 5 of the ice-making module, and after the refrigerant flows through the ice-making mold 1, the refrigerant will absorb heat and become a higher-temperature state. At this time, the refrigerant can be used as a condensing agent and introduced into the pipe inlet 32 of the heating pipe 31, and then returned to the compressor from the pipe outlet 33. Through the above arrangement, the heating pipe 31 can directly use the refrigeration components (evaporator and compressor structures, etc.) in the ice-making module, so that additional structures do not need to be separately arranged, thereby reducing the overall structure and cost.

[0033] Further, as shown in Figure 6 , the side of the evaporator shell 4 away from the ice-making inner groove 2 is provided with a first water flow corner 14, a second water flow corner 15, a third water flow corner 16, and a fourth water flow corner 17. The first water flow corner 14 is lower than the fourth water flow corner 17, and the second water flow corner 15 is lower than the third water flow corner 16. The refrigerant inlet 6 is arranged at the first water flow corner 14, and the refrigerant outlet 7 is arranged at the third water flow corner 16.

[0034] As shown in Figure 5 , the flow distribution assembly further includes a flow guide channel 18, and the flow guide channel 18 corresponds to the ice-making inner groove 2 one by one. The flow guide channel 18 includes a transverse channel 19 and a longitudinal channel 20. The recess 13 is located in the corresponding transverse channel 19, and the ice-making inner groove 2 is located in the corresponding longitudinal channel 20.

[0035] The flow guide channel 18 can make the water flow through the corresponding ice-making inner groove 2, rather than entering the adjacent ice-making inner groove 2, so that the size of the ice blocks in each ice-making inner groove 2 is consistent during ice making. In addition, the flow guide channel 18 can also avoid adhesion between adjacent ice blocks.

[0036] The following is another embodiment of the water supply device, as shown in Figures 10-16 , the water supply device includes a second water supply pipe 21, and the second water supply pipe 21 is fixed on the side of the evaporator shell 4 by a second support 22. The evaporator shell 4 is provided with an arc-shaped protruding portion 34 located above the opening of the ice-making inner groove 2. The second water supply pipe 21 is provided with a plurality of second water supply holes 35, and the second water supply holes 35 are arranged in sequence along the length direction of the second water supply pipe 21. Each ice-making inner groove 2 can correspond to at least one second water supply hole 35, and the corresponding ice-making inner groove 2 can be supplied with water through one or more second water supply holes 35.

[0037] By introducing water into the second water supply pipe 21, the water flows towards the arc-shaped protruding portion 34, and the water enters the ice-making inner groove 2 along the arc-shaped protruding portion 34, and then flows through the inside of the ice-making inner groove 2 and is discharged. The ice in the ice-making inner groove 2 thickens layer by layer, and finally forms a whole ice block.

[0038] As Figures 10-16 shown, the cavity 5 is fixed with a partition 36, the partition 36 separates the cavity 5 into an upper cavity 37 and a lower cavity 38, a communication groove 39 is arranged between the upper cavity 37 and the lower cavity 38, the communication groove 39 is higher than the bottom of the upper cavity 37, the refrigerant inlet 6 communicates with the upper cavity 37, and the refrigerant outlet 7 communicates with the lower cavity 38.

[0039] The refrigerant enters the upper cavity 37 through the refrigerant inlet 6, and then the refrigerant rises in the upper cavity 37, enters the lower cavity 38 through the communication groove 39 after rising to the height of the communication groove 39, so that the refrigerant can slowly sink to the bottom of the cavity 5, and the refrigeration in the upper and lower directions of the cavity 5 is more uniform.

[0040] As Figure 15 shown, the refrigerant outlet 7 is arranged at the bottom of the lower cavity 38, the refrigerant outlet 7 is fixed with a discharge pipe 41, the discharge pipe 41 is provided with a discharge inlet 42 and a discharge outlet 40, the discharge inlet 42 is arranged at the top of the upper cavity 37, and the discharge outlet 40 is arranged on the outside of the evaporator shell 4.

[0041] The refrigerant enters the upper cavity 37 through the refrigerant inlet 6, and then the refrigerant rises in the cavity 5, enters the lower cavity 38 after rising to the height of the communication groove 39, and when the refrigerant in the lower cavity 38 is full, the refrigerant in the upper cavity 37 enters the discharge pipe 41 through the discharge inlet 42, and then is discharged from the discharge outlet 40.

[0042] As Figure 15 shown, the side wall of the discharge pipe 41 is provided with a discharge side hole 23, the discharge side hole 23 communicates with the lower cavity 38, and the discharge side hole 23 is arranged close to the bottom of the lower cavity 38. The discharge side hole 23 enables the liquefied refrigerant in the lower cavity 38 to flow back to the compressor, so as not to accumulate in the refrigeration cavity and affect refrigeration. The discharge side hole 23 has a small diameter, which can reduce the refrigerant entering the discharge pipe 41 through the discharge side hole 23 in normal refrigeration.

[0043] As Figure 13 shown, the evaporator shell 4 is further fixed with a heat pipe 43, the heat pipe 43 communicates with the lower part of the cavity 5, when defrosting is needed, hot gas can be introduced into the cavity 5 through the heat pipe 43 to realize defrosting, and the heat pipe 43 is closed during the refrigeration process.
