Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to an ice maker. Background Technology

[0002] An ice maker is a refrigeration machine that cools water through an evaporator using a refrigerant in a refrigeration system to produce ice cubes. It can be placed in a kitchen, living room, or bedroom. However, in some related technologies, the dimensions between the front and back of the ice maker are too large, meaning the ice maker is quite thick. Since kitchens and bedrooms typically have limited space, this makes it difficult to place a thick ice maker, thus restricting its use. Utility Model Content

[0006] In one embodiment, the ice-making columns are arranged in two or three columns, with each column of ice-making columns extending along the second direction.

[0007] In one embodiment, the ice-making columns are arranged in two rows; The evaporation tube includes a first tube segment, a second tube segment, and a connecting tube segment. The first tube segment and the second tube segment both extend in a straight line along the second direction and are arranged at intervals along the first direction. The connecting tube segment is arc-shaped and connects to the same end of the first tube segment and the second tube segment. One row of ice-making columns is connected to the first tube segment, and another row of ice-making columns is connected to the second tube segment. Alternatively, the evaporator tube may include a first tube segment that extends in a wavy pattern along the second direction, with both rows of ice-making columns connected to the first tube segment.

[0008] In one embodiment, the ice-making column is arranged in three rows; The evaporation tube includes a first tube segment, a second tube segment, a third tube segment, and two connecting tube segments. The first tube segment, the second tube segment, and the third tube segment all extend in a straight line along the second direction and are arranged at intervals along the first direction. The connecting tube segments are arc-shaped. One connecting tube segment connects the first tube segment and the second tube segment, and the other connecting tube segment connects the second tube segment and the third tube segment. The two connecting tube segments are respectively connected to the two ends of the second tube segment. The first tube segment, the second tube segment, and the third tube segment are respectively connected to a row of ice-making columns. Alternatively, the evaporator tube includes a first tube segment, a second tube segment, and a connecting tube segment. The first tube segment and the second tube segment both extend along the second direction and are arranged at intervals along the first direction.

[0009] In one embodiment, the evaporator tube is provided with a refrigerant inlet and a refrigerant outlet. The refrigerant inlet is used to communicate with the condenser, and the refrigerant outlet is used to communicate with the compressor.

Compared to other arrangements of the three components, this arrangement can shorten the dimensions of the ice maker in the front-to-back direction, thereby reducing the overall dimensions of the ice maker and increasing the likelihood of placing the ice maker in a confined space. By arranging multiple ice columns in a staggered array in the first and second directions, compared to a direct-facing arrangement of the ice columns, a larger quantity of large ice blocks can be produced within the limited space of the ice-making tank. Furthermore, it helps to reduce the size of the evaporator in the first or second direction, saving space for the tilting of the ice-making container and thus reducing the overall height of the machine.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0018] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model. Furthermore, in this application, "above" and "below" refer to the vertical direction above and below when the bottom of the ice maker is placed on a horizontal support platform; "front" refers to the side of the ice maker facing the user when the bottom of the ice maker is placed on a horizontal support platform; and "rear" refers to the side of the ice maker facing away from the user when the bottom of the ice maker is placed on a horizontal support platform.

[0019] Example 1: like Figures 1 to 4 As shown, the ice maker 100 provided in this embodiment of the present invention includes a housing 10, an ice-making component 20, a compressor 30, and a condenser 40. The ice-making component 20, the compressor 30, and the condenser 40 are all disposed inside the housing 10 and are arranged sequentially along the first direction X.

[0020] Among the components of the ice maker 100, the ice-making assembly 20, compressor 30, and condenser 40 are relatively large. By arranging the ice-making assembly 20, compressor 30, and condenser 40 sequentially along the first direction X, the first direction X can be set to either left to right or right to left. This arrangement, compared to other arrangements of the three components, can shorten the dimensions of the ice maker 100 in the front-back direction, thereby reducing the overall dimensions of the ice maker 100 and increasing the likelihood that the ice maker 100 can be placed in a narrow space.

[0021] Please see Figures 3 to 5 The ice-making assembly 20 is provided with an ice-making tank 221. The ice maker 100 also includes an evaporator 50 communicating with the compressor 30 and the condenser 40. The evaporator 50 includes a plurality of ice-making columns 51, and at least a portion of each ice-making column 51 extends into the ice-making tank 221. The plurality of ice-making columns 51 are arranged in a staggered array in a first direction X and a second direction Y, and the first direction X and the second direction Y intersect.

[0022] It should be noted that the staggered array arrangement of multiple ice-making columns 51 means that multiple ice-making columns 51 are arranged in an array, and the ice-making columns 51 in adjacent columns or adjacent rows are staggered. For example, Figure 6 In the middle, from right to left, the ice-making columns 51a and 51b in the first column and the ice-making column 51c in the second column are arranged in an isosceles triangle or an equilateral triangle, with the ice-making column 51c in the second column located at the apex of the triangle, and the ice-making column 51c is staggered with the ice-making columns 51a and 51b.

[0023] By employing the above technical solution, with at least a portion of the ice-making column 51 extending into the ice-making tank 221, when the refrigerant flows through the ice-making column 51, the refrigerant absorbs heat from the area surrounding the ice-making column 51, causing ice to form in the water surrounding the ice-making column 51 within the ice-making tank 221. By arranging multiple ice-making columns 51 in a staggered array along the first direction X and the second direction Y, compared to a directly facing arrangement of the ice-making columns 51, a larger quantity of large ice blocks can be produced within the limited space of the ice-making tank 221. Furthermore, this reduces the size of the evaporator 50 along either the first direction X or the second direction Y, saving space for the tilting of the ice-making container 22, thereby reducing the overall height of the machine.

[0024] In one embodiment, the first direction X and the second direction Y are perpendicular. Of course, in other embodiments, the first direction X and the second direction Y may not be perpendicular. In a specific application, the first direction X is in the left-right direction of the ice maker 100, and the second direction Y is in the front-back direction of the ice maker 100. Please see Figure 2 , Figure 3 and Figure 5 The evaporator 50 also includes an evaporator tube 52, with each ice-making column 51 connected to the side of the evaporator tube 52 facing the ice-making tank 221. One end of the evaporator tube 52 is connected to the compressor 30, and the other end is connected to the condenser 40. In specific applications, the ice maker 100 also includes a capillary tube (not shown), which is connected between the condenser 40 and the evaporator tube 52, i.e., the other end of the evaporator tube 52 is connected to the capillary tube. Refrigerant flows from the capillary tube into the evaporator tube 52, flows through each ice-making column 51 in sequence, and then flows from the evaporator tube 52 into the compressor 30. The evaporator tube 52 may be positioned above the ice-making tank 221.

[0025] The evaporator tube 52 is equipped with a refrigerant inlet 525 and a refrigerant outlet 526. The refrigerant inlet 525 is used to connect with the condenser 40, and the refrigerant outlet 526 is used to connect with the compressor 30. Specifically, the refrigerant inlet 525 is connected to a capillary tube. In this way, the evaporator tube 52 is connected to the condenser 40 and the compressor 30.

[0026] In one embodiment, the refrigerant inlet 525 and the refrigerant outlet 526 are located on the same side of the evaporator tube 52, or the refrigerant inlet 525 and the refrigerant outlet 526 are located on opposite sides of the evaporator tube 52. In specific applications, the refrigerant inlet 525 and the refrigerant outlet 526 can be positioned on the same side or opposite sides of the evaporator tube 52, depending on the arrangement of the components in the ice maker 100. When the refrigerant inlet 525 and the refrigerant outlet 526 are located on the same side of the evaporator tube 52, the two pipes connected to the evaporator tube 52 for transporting refrigerant are located on the same side of the evaporator tube 52; when the refrigerant inlet 525 and the refrigerant outlet 526 are located on opposite sides of the evaporator tube 52, the two pipes connected to the evaporator tube 52 for transporting refrigerant are located on opposite sides of the evaporator tube 52.

[0027] In one embodiment, the ice-making columns 51 are arranged in two or three columns, each column extending along the second direction Y. Of course, in other embodiments, the ice-making columns 51 can also be arranged in four or five columns, etc. It should be noted that this embodiment does not limit the number of columns of the ice-making columns 51. In this embodiment, the ice-making columns 51 are arranged in two columns.

[0028] Please see Figure 5 and Figure 6 The evaporator tube 52 includes a first tube section 521, a second tube section 522, and a connecting tube section 524. Both the first tube section 521 and the second tube section 522 extend linearly along the second direction Y and are spaced apart along the first direction X. The connecting tube section 524 is arc-shaped and connects to the same end of the first tube section 521 and the second tube section 522. One row of ice-making columns 51 is connected to the first tube section 521, and another row of ice-making columns 51 is connected to the second tube section 522. With this arrangement, the evaporator tube 52 is U-shaped, and the refrigerant inlet 525 and the refrigerant outlet 526 are located on the same side of the evaporator tube 52. The evaporator tube 52 has a simple structure and is easy to manufacture.

[0029] In this embodiment, the refrigerant inlet 525 is located in the first pipe section 521, and the refrigerant outlet 526 is located in the second pipe section 522. It is understood that in other embodiments, the refrigerant inlet 525 may also be located in the second pipe section 522, and the refrigerant outlet 526 may also be located in the first pipe section 521.

[0030] In one embodiment, the number of ice-making columns 51 connected to the first pipe section 521 is greater than the number of ice-making columns 51 connected to the second pipe section 522. The refrigerant in the evaporator pipe 52 near the refrigerant inlet 525 has a better cooling effect. Setting the number of ice-making columns 51 connected to the first pipe section 521 greater than the number connected to the second pipe section 522 can improve the refrigerant utilization efficiency. It is understood that in other embodiments, the number of ice-making columns 51 connected to the first pipe section 521 may also be equal to or greater than the number of ice-making columns 51 connected to the second pipe section 522.

[0031] In one embodiment, the outer surface of the ice-making column 51 is provided with a non-stick coating. This facilitates the removal of ice from the ice-making column 51. Of course, in other embodiments, the outer surface of the ice-making column 51 may not have a non-stick coating.

[0032] Please see Figure 3 and Figure 4 The ice-making assembly 20 includes a housing 21 and an ice-making container 22. The housing 21 contains a water storage tank 211 and an ice storage tank 212. The water storage tank 211 and the ice storage tank 212 are arranged side-by-side along a first direction X and both extend along a second direction Y. The openings of the water storage tank 211 and the ice storage tank 212 are adjacent to each other in the first direction X. The ice-making container 22 has an ice-making tank 221, and the water storage tank 211 receives ice-making water from the ice-making tank 221. In specific applications, the ice-making container 22 is positioned above the water storage tank 211. Residual ice-making water in the ice-making tank 221 is transferred to the water storage tank 211, while the prepared ice is transferred to the ice storage tank 212. Residual ice-making water does not transfer to the ice storage tank 212 and therefore does not flow through the ice already stored in the ice storage tank 212, thus reducing the risk of ice sticking together in the ice storage tank 212. In addition, the water storage tank 211 and the ice storage tank 212 are arranged side by side along the first direction X and both extend along the second direction Y. The ice making container 22 is set above the water storage tank 211 and also extends along the second direction Y. This arrangement can maximize the space of the ice storage tank 212 and the ice making tank 221 within a limited space.

[0033] In one embodiment, the ice-making assembly 20 further includes an ice storage container 23, which is disposed at the opening of the water storage tank 211 and extends to the opening of the ice storage tank 212. The ice storage container 23 has an ice storage trough 231 and multiple perforations (not shown). The multiple perforations are disposed at the bottom of the ice storage container 23 to connect the ice storage trough 231 and the water storage tank 211. The ice storage container 23 is used to receive ice and ice-making water from the ice-making container 22 and to transport the ice-making water to the water storage tank 211.

[0034] In practical applications, the ice-making container 22 is located above the ice storage container 23 and corresponds to the opening of the ice storage tank 231. During use, the ice-making container 22 can be flipped relative to the ice storage container 23 so that the opening of the ice-making tank 221 faces downward, thereby transferring the ice and ice-making water in the ice-making tank 221 to the ice storage tank 231. The ice-making water can flow into the water storage tank 211 through the perforation, thus achieving the separation of ice and ice-making water.

[0035] Please see Figure 3 and Figure 4 The ice-making assembly 20 also includes a cold water tank 24, which is located below the housing 21. Both the water storage tank 211 and the ice storage tank 212 are connected to the cold water tank 24. This allows for the collection of ice-making water.

[0036] In one embodiment, the cold water tank 24 is connected to the ice-making tank 221 so that the ice-making water in the cold water tank 24 can flow back into the ice-making tank 221 and continue to be used to make ice. Since the temperature of the ice-making water in the cold water tank 24 is lower than that of room temperature water, this portion of the water flowing back into the ice-making tank 221 and continuing to be used to make ice can reduce energy consumption.

[0037] In one embodiment, the cold water tank 24 is connected to the cold water outlet of the ice maker 100, so that the ice-making water in the cold water tank 24 can be discharged from the cold water outlet to provide cold water (temperature lower than room temperature water) to the user.

[0038] In one embodiment, the ice maker 100 further includes a circuit board 60, which is disposed on one side of the ice-making assembly 20 along the second direction Y. In specific applications, the circuit board 60 may be disposed in front of the ice-making assembly 20.

[0039] Example 2: Please see Figure 5 and Figure 7 The ice maker 100 provided in this embodiment differs from that in Embodiment 1 in that the evaporator 52 is configured differently. Specifically, in Embodiment 1, the evaporator 52 includes a first pipe section 521, a second pipe section 522, and a connecting pipe section 524; while in this embodiment, the evaporator 52 includes a first pipe section 521.

[0040] In this embodiment, the evaporator tube 52 includes a first tube segment 521, which extends in a wavy shape along the second direction Y. Both rows of ice-making columns 51 are connected to the first tube segment 521. With this arrangement, the evaporator tube 52 is wavy, and the refrigerant inlet 525 and refrigerant outlet 526 are located on opposite sides of the evaporator tube 52.

[0041] Apart from the differences mentioned above, the ice maker 100 and its auxiliary components provided in this embodiment can be designed with reference to Embodiment 1, and will not be described further here.

[0042] Example 3: Please see Figure 5 and Figure 8 The ice maker 100 provided in this embodiment differs from those in embodiments one and two in that the number of columns of ice-making columns 51 is different. Specifically, in embodiment one, the ice-making columns 51 are arranged in two columns; while in this embodiment, the ice-making columns 51 are arranged in three columns.

[0043] In this embodiment, the ice-making columns 51 are arranged in three rows. The evaporator tube 52 includes a first tube segment 521, a second tube segment 522, a third tube segment 523, and two connecting tube segments 524. The first tube segment 521, the second tube segment 522, and the third tube segment 523 all extend in a straight line along the second direction Y and are arranged alternately along the first direction X. The connecting tube segments 524 are arc-shaped. One connecting tube segment 524 connects between the first tube segment 521 and the second tube segment 522, and the other connecting tube segment 524 connects between the second tube segment 522 and the third tube segment 523. The two connecting tube segments 524 are respectively connected to the two ends of the second tube segment 522. The first tube segment 521, the second tube segment 522, and the third tube segment 523 are each connected to one row of ice-making columns 51. In this embodiment, the refrigerant inlet 525 and the refrigerant outlet 526 are located on opposite sides of the evaporator tube 52.

[0044] Apart from the differences mentioned above, the ice maker 100 and its auxiliary components provided in this embodiment can be designed with reference to Embodiments 1 and 2, and will not be described further here.

[0045] Example 4: Please see Figure 5 and Figure 9 The difference between the ice maker 100 provided in this embodiment and that in embodiment three is the different arrangement of the evaporation tube 52. Specifically, in embodiment three, the evaporation tube 52 includes a first tube segment 521, a second tube segment 522, a third tube segment 523 and two connecting tube segments 524; while in this embodiment, the evaporation tube 52 includes a first tube segment 521, a second tube segment 522 and a connecting tube segment 524.

[0046] In this embodiment, the evaporator tube 52 includes a first tube segment 521, a second tube segment 522, and a connecting tube segment 524. Both the first tube segment 521 and the second tube segment 522 extend along a second direction Y and are spaced apart along a first direction X. The first tube segment 521 is wavy, and the second tube segment 522 is straight. Two adjacent rows of ice-making columns 51 are connected to the first tube segment 521, and the remaining row of ice-making columns 51 is connected to the second tube segment 522. The connecting tube segment 524 is arc-shaped and connects to the same end of the first tube segment 521 and the second tube segment 522. In this embodiment, the refrigerant inlet 525 and the refrigerant outlet 526 are located on the same side of the evaporator tube 52.

[0047] Apart from the differences mentioned above, the ice maker 100 and its auxiliary components provided in this embodiment can be designed with reference to embodiments one to three, and will not be described further here.
