Description

Technical Field

[0001] The utility model relates to the technical field of ice maker equipment, and particularly to an ice maker evaporator. Background Art

[0002] An ice maker is a refrigeration mechanical device that cools water through an evaporator by a refrigerant of a refrigeration system to generate ice. The evaporator is an important component of the ice maker, including an evaporation pipe and an ice making mold. A refrigerant is introduced into the evaporation pipe, and heat exchange is carried out between the evaporation pipe and the ice making mold, so that the ice making mold is cooled and the water on the ice making mold is frozen, achieving the purpose of quickly obtaining ice cubes.

[0003] For example, a Chinese patent with the publication number CN219433552U discloses an ice maker evaporator, including an ice template. A serpentine evaporation pipe is provided on one side surface of the ice template, and the serpentine evaporation pipe is attached to the ice template. A plurality of squares are arranged in a dot matrix on the other side surface of the ice template. A pressing component is provided between the ice template and the serpentine evaporation pipe, and two fixing components are provided on both sides of the pressing component. The fixing components are arranged between the ice template and the serpentine evaporation pipe. The serpentine evaporation pipe is fixed on the ice template through the fixing components and the pressing component, and the serpentine evaporation pipe is closely attached to the ice template. When the serpentine evaporation pipe is damaged and leaks, the fixing components and the pressing component can be removed to release the locking between the ice template and the serpentine evaporation pipe, and the replacement operation is simple and convenient. Although the structural setting of the above ice maker evaporator can make the operation of replacing the evaporation pipe simple and convenient, the contact area between the evaporation pipe and the ice template is small, resulting in poor overall refrigeration effect of the ice maker evaporator.

[0004] Therefore, the prior art still needs to be improved and developed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an ice maker evaporator aiming at the defects and deficiencies of the prior art.

[0006] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0007] The utility model provides an ice maker evaporator, including an ice making mold, an evaporation pipe and a pressing cover plate; a groove is provided on the top surface of the ice making mold, and the evaporation pipe is placed in the groove; the height of the evaporation pipe is greater than the depth of the groove, and the width of the groove is greater than the width of the evaporation pipe; the pressing cover plate is detachably fixed on the top surface of the ice making mold; the evaporation pipe matches the groove. When the pressing cover plate is arranged on the top surface of the ice making mold, the pressing cover plate extrudes the part of the evaporation pipe exposed outside the groove, so that the evaporation pipe is deformed and attached to the side wall of the groove.

[0008] By setting the width of the groove to be greater than that of the evaporation tube, a gap is left between the side wall of the groove and the evaporation tube, so that the evaporation tube can be deformed within the gap under the extrusion of the pressing cover plate; by the extrusion of the pressing cover plate, the evaporation tube is attached to the side wall of the groove, increasing the contact area between the evaporation tube and the ice-making mold, thus facilitating the improvement of the refrigeration efficiency; and when the evaporation tube needs to be replaced, only the pressing cover plate needs to be removed, and then the evaporation tube can be taken out from the groove, and the replacement operation is simple and convenient.

[0009] It can be understood that only by leaving a gap between the side wall of the groove and the evaporation tube can the evaporation tube have space for deformation.

[0010] According to the above solution, the cross-section of the groove is arc-shaped, and the cross-section of the evaporation tube before being extruded by the pressing cover plate is circular; the ratio of the width of the groove to the diameter of the evaporation tube is 1.2 - 1.6, and the ratio of the depth of the groove to the diameter of the evaporation tube is 0.6 - 0.9.

[0011] By adjusting the ratio of the width of the groove to the diameter of the evaporation tube and the ratio of the depth of the groove to the diameter of the evaporation tube, the contact area between the evaporation tube and the side wall of the groove when the evaporation tube is extruded and deformed by the pressing cover plate can be adjusted.

[0012] According to the above solution, the surface of the groove is coated with a heat-conducting layer. The heat-conducting layer can be a heat-conducting silicone grease layer, etc., and the present invention is not limited thereto. By coating with the heat-conducting layer, the heat conductivity between the evaporation tube and the ice-making mold is further improved.

[0013] According to the above solution, it further includes a heat-insulating board, which is detachably fixed on the top surface of the ice-making mold, or the heat-insulating board is fixed on the bottom surface of the pressing cover plate. The heat-insulating board can be made of materials with good heat-insulating performance such as foam, and the present invention is not limited thereto.

[0014] Through the above structural arrangement, the evaporation tube is located between the heat-insulating board and the ice-making mold, which is beneficial to reducing the loss of cold quantity of the evaporation tube.

[0015] According to the above solution, it further includes a housing, the side surface of the ice-making mold is wrapped by the housing, and a heat-insulating material is filled between the side surface of the ice-making mold and the housing.

[0016] Through the above structural arrangement, the filled heat-insulating material can greatly increase the heat-insulating effect of the ice-making mold, reduce the loss during the transfer of cold quantity from the ice-making mold to the ice-making cavity, and is beneficial to improving the ice-making effect.

[0017] According to the above solution, a positioning shoulder is provided around the outer periphery of the bottom surface of the ice-making mold, and the positioning shoulder abuts against the lower opening of the outer shell; an upper cover is detachably fixed on the outer shell, and the upper cover presses against the ice-making mold. Through the above structural arrangement, the convenience of installing the ice-making mold in the outer shell is improved; through the action of the upper cover and the positioning shoulder, the ice-making mold can be prevented from moving up and down in the outer shell.

[0018] According to the above solution, the evaporation pipes are symmetrically distributed on the top surface of the ice-making mold with the center line of the ice-making mold as the axis of symmetry, and a plurality of ice-making cavities are provided on the bottom surface of the ice-making mold. The evaporation pipes exchange heat with the ice-making mold, so that the ice-making mold is cooled and the water in the ice-making cavities freezes quickly.

[0019] According to the above solution, the evaporation pipe includes a liquid inlet straight pipe, a plurality of first straight pipes, a plurality of second straight pipes and a liquid outlet straight pipe connected in sequence, and the straight pipes are connected by arc-shaped pipes; the liquid inlet straight pipe, the first straight pipes, the second straight pipes and the liquid outlet straight pipe are arranged in parallel, and the liquid inlet straight pipe and the liquid outlet straight pipe are adjacent and symmetrically arranged with the center line of the ice-making mold as the axis of symmetry.

[0020] The refrigerant flows into the evaporation pipe from the inlet of the liquid inlet straight pipe and finally flows out from the outlet of the liquid outlet straight pipe. The liquid inlet straight pipe is the place with the lowest temperature of the whole evaporation pipe, and the liquid outlet straight pipe is the place with the highest temperature of the whole evaporation pipe; the liquid inlet straight pipe and the liquid outlet straight pipe are adjacent and symmetrically arranged with the center line of the ice-making mold as the axis of symmetry, reducing the temperature difference between the liquid inlet straight pipe and the liquid outlet straight pipe. The refrigerant first flows through the middle position of the ice-making mold and then flows to the surrounding, and finally flows back to the middle position, which is beneficial to improving the ice-making effect.

[0021] It can be understood that since the evaporation pipe is axisymmetric, the liquid inlet straight pipe and the liquid outlet straight pipe are axisymmetric, and the plurality of first straight pipes are respectively axisymmetric with the plurality of second straight pipes.

[0022] According to the above solution, the distance between the liquid inlet straight pipe and the liquid outlet straight pipe is set as X, the distance between the liquid inlet straight pipe and the adjacent first straight pipe is set as Y, and the distance between two adjacent first straight pipes is set as Z; wherein, Y>X, Z>X, and the values of X / Z and X / Y are respectively 0.4 to 0.8.

[0023] Through the above structural arrangement, the distance between the liquid inlet straight pipe and the liquid outlet straight pipe is smaller than the distance between other adjacent straight pipes, which is beneficial to reducing the temperature difference between the liquid inlet straight pipe and the liquid outlet straight pipe.

[0024] It can be understood that since the plurality of first straight pipes are respectively axisymmetric with the plurality of second straight pipes, the distance between the liquid outlet straight pipe and the adjacent second straight pipe is also Y, and the distance between two adjacent second straight pipes is also Z; the values of Y and Z can be the same or different.

[0025] According to the above solution, the ice-making mold is stepped, and its cross-section is T-shaped. By setting the cross-section of the ice-making mold to be T-shaped, the top surface area of the ice-making mold is larger than the bottom surface area of the ice-making mold. In this way, after the evaporation pipe is installed on the top surface of the ice-making mold, it can completely cover the ice-making mold in terms of area, which is beneficial to improving the ice-making effect.

[0026] The beneficial effects of the present utility model are as follows:

[0027] The present utility model is provided with a groove on the top surface of the ice-making mold. The evaporation pipe is placed in the groove. The width of the groove is greater than the width of the evaporation pipe, so that there is a gap between the side wall of the groove and the evaporation pipe, so that the evaporation pipe can be deformed in the gap under the extrusion of the pressing cover plate; the pressing cover plate is detachably fixed on the top surface of the ice-making mold, and the pressing cover plate is used to extrude the part of the evaporation pipe exposed outside the groove. Through the extrusion of the pressing cover plate, the evaporation pipe is attached to the side wall of the groove, increasing the contact area between the evaporation pipe and the ice-making mold, which is beneficial to improving the refrigeration efficiency; and when the evaporation pipe needs to be replaced, only need to remove the pressing cover plate, and then take out the evaporation pipe from the groove. The replacement operation is simple and convenient. Description of the Drawings

[0038] The technical solutions of the present invention will be described below in conjunction with the drawings and embodiments.

[0039] Embodiment 1

[0040] As Figure 1-8 shown, the present invention provides an ice maker evaporator, including an ice-making mold 1, an evaporation tube 2 and a pressure cover plate 3; a groove 11 is provided on the top surface of the ice-making mold 1, and the evaporation tube 2 is placed in the groove 11; the height of the evaporation tube 2 is greater than the depth of the groove 11, and the width of the groove 11 is greater than the width of the evaporation tube 2; the pressure cover plate 3 is detachably fixed on the top surface of the ice-making mold 1; the evaporation tube 2 matches the groove 11, and when the pressure cover plate 3 is arranged on the top surface of the ice-making mold 1, the pressure cover plate 3 squeezes the part of the evaporation tube 2 exposed outside the groove 11, so that the evaporation tube 2 is deformed and fits with the side wall of the groove 11.

[0041] By setting the width of the groove 11 to be greater than the width of the evaporation tube 2, a gap 111 is left between the side wall of the groove 11 and the evaporation tube 2, so that the evaporation tube 2 can be deformed in the gap 111 under the extrusion of the pressure cover plate 3; by the extrusion of the pressure cover plate 3, the evaporation tube 2 fits with the side wall of the groove 11, increasing the contact area between the evaporation tube 2 and the ice-making mold 1, thus being beneficial to improving the refrigeration efficiency.

[0042] It can be understood that only by setting a gap 111 between the side wall of the groove 11 and the evaporation tube 2 can the evaporation tube 2 have a space for deformation.

[0043] Furthermore, the cross-section of the groove 11 is arc-shaped, and the cross-section of the evaporation tube 2 before being squeezed by the pressure cover plate 3 is arc-shaped; the ratio of the width of the groove 11 to the diameter of the evaporation tube 2 is 1.2 - 1.6, and the ratio of the depth of the groove 11 to the diameter of the evaporation tube 2 is 0.6 - 0.9.

[0044] That is, the width of the groove 11 is greater than the diameter of the evaporation tube 2, and the depth of the groove 11 is less than the diameter of the evaporation tube 2. With such a setting, under the extrusion of the pressure cover plate 3, the deformation of the evaporation tube 2 can achieve the technical purpose of fitting with the side wall of the groove 11.

[0045] It is understandable that by adjusting the ratio of the width of the groove 11 to the diameter of the evaporation tube 2 and the ratio of the depth of the groove 11 to the diameter of the evaporation tube 2, the area of the evaporation tube 2 in contact with the side wall of the groove 11 can be made different when the evaporation tube 2 is deformed by the pressing cover plate 3.

[0046] Furthermore, the surface of the groove 11 is coated with a heat-conducting layer (not shown in the figure). The heat-conducting layer can be a heat-conducting silicone grease layer, etc., and the present utility model is not limited thereto. By coating with the heat-conducting layer, the heat conductivity between the evaporation tube 2 and the ice-making mold 1 is further improved.

[0047] Furthermore, in order to further improve the refrigeration effect, it further includes a heat-insulating plate 31, and the heat-insulating plate 31 is detachably fixed on the top surface of the ice-making mold 1. The heat-insulating plate 31 can be made of a material with good heat-insulating performance such as foam, and the present utility model is not limited thereto.

[0048] Through the above structural arrangement, after the evaporation tube 2 is squeezed by the pressing cover plate 3, the pressing cover plate 3 can be removed, and then the heat-insulating plate 31 is fixed on the top surface of the ice-making mold 1, so that the evaporation tube 2 is located between the heat-insulating plate 31 and the ice-making mold 1, which is beneficial to reducing the loss of cold energy of the evaporation tube 2.

[0049] Furthermore, it further includes a housing 4, the side surface of the ice-making mold 1 is wrapped by the housing 4, and a heat-insulating material (not shown in the figure) is filled between the side surface of the ice-making mold 1 and the housing 4.

[0050] Through the above structural arrangement, the filled heat-insulating material can greatly increase the heat-insulating effect of the ice-making mold 1, reduce the loss during the transfer of cold energy from the ice-making mold 1 to the ice-making cavity 12, and is beneficial to improving the ice-making effect.

[0051] Furthermore, a circumferential positioning shoulder 13 is provided on the outer periphery of the bottom surface of the ice-making mold 1, and the positioning shoulder 13 abuts against the lower opening of the housing 4; an upper cover 41 is detachably fixed on the housing 4, and the upper cover 41 presses against the ice-making mold 1. Through the above structural arrangement, the convenience of installing the ice-making mold 1 in the housing 4 is improved; through the action of the upper cover 41 and the positioning shoulder 13, the ice-making mold 1 can be prevented from moving up and down in the housing 4.

[0052] Furthermore, the evaporation tubes 2 are symmetrically distributed on the top surface of the ice-making mold 1 with the center line of the ice-making mold 1 as the axis of symmetry, and a plurality of ice-making cavities 12 are provided on the bottom surface of the ice-making mold 1. The evaporation tubes 2 exchange heat with the ice-making mold 1, so that the ice-making mold 1 is cooled and the water in the ice-making cavities 12 freezes quickly.

[0053] Furthermore, the evaporation tube 2 includes a liquid inlet straight tube 21, a plurality of first straight tubes 22, a plurality of second straight tubes 23, and a liquid outlet straight tube 24 that are connected in sequence. The straight tubes are connected by an arc-shaped tube 25; the liquid inlet straight tube 21, the first straight tubes 22, the second straight tubes 23, and the liquid outlet straight tube 24 are arranged in parallel. The liquid inlet straight tube 21 and the liquid outlet straight tube 24 are adjacent and symmetrically arranged with the center line of the ice-making mold 1 as the axis of symmetry.

[0054] The refrigerant flows into the evaporation tube 2 from the inlet of the liquid inlet straight tube 21 and finally flows out from the outlet of the liquid outlet straight tube 24. The liquid inlet straight tube 21 is the location with the lowest temperature in the entire evaporation tube 2, and the liquid outlet straight tube 24 is the location with the highest temperature in the entire evaporation tube 2; the liquid inlet straight tube 21 and the liquid outlet straight tube 24 are adjacent and symmetrically arranged with the center line of the ice-making mold 1 as the axis of symmetry, reducing the temperature difference between the liquid inlet straight tube 21 and the liquid outlet straight tube 24. The refrigerant first flows through the middle position of the ice-making mold 1 and then flows to the surroundings, and finally flows back to the middle position, which is beneficial to improving the ice-making effect.

[0055] It can be understood that the evaporation tube 2 is axisymmetric, so the liquid inlet straight tube 21 and the liquid outlet straight tube 24 are axisymmetric, and the plurality of first straight tubes 22 are respectively axisymmetric with the plurality of second straight tubes 23.

[0056] Furthermore, the distance between the liquid inlet straight tube 21 and the liquid outlet straight tube 24 is set as X, the distance between the liquid inlet straight tube 21 and the adjacent first straight tube 22 is set as Y, and the distance between two adjacent first straight tubes 22 is set as Z; among them, Y > X, Z > X, and the values of X / Z and X / Y are 0.4 - 0.8 respectively.

[0057] Through the above structural settings, the distance between the liquid inlet straight tube 21 and the liquid outlet straight tube 24 is smaller than the distance between other adjacent straight tubes, which is beneficial to reducing the temperature difference between the liquid inlet straight tube 21 and the liquid outlet straight tube 24.

[0058] It can be understood that since the plurality of first straight tubes 22 are respectively axisymmetric with the plurality of second straight tubes 23, the distance between the liquid outlet straight tube 24 and the adjacent second straight tube 23 is also Y, and the distance between two adjacent second straight tubes 23 is also Z; the values of Y and Z can be the same or different.

[0059] Furthermore, the ice-making mold 1 is in a stepped shape, and its cross-section is T-shaped. By setting the cross-section of the ice-making mold 1 to be T-shaped, the top surface area of the ice-making mold 1 is larger than the bottom surface area of the ice-making mold 1. In this way, after the evaporation tube 2 is installed on the top surface of the ice-making mold 1, it can completely cover the ice-making mold 1 in terms of area, which is beneficial to improving the ice-making effect.

[0060] When the ice-making machine evaporator of the present utility model is assembled, such as Figure 1-3As shown in the figure, first place the ice-making mold 1 into the outer shell 4, fill heat-insulating material between the side surface of the ice-making mold 1 and the outer shell 4, and place the evaporation tube 2 with a circular cross-section into the groove 11 with an arc-shaped cross-section; as Figure 4-5 shown in the figure, then press the cover plate 3 against the top surface of the ice-making mold 1 and fix it on the top surface of the ice-making mold 1. At this time, the cover plate 3 will squeeze the top of the evaporation tube 2 exposed outside the groove 11, causing the evaporation tube 2 to deform and fit with the side wall of the groove 11; then remove the cover plate 3 from the top surface of the ice-making mold 1, as Figure 6-7 shown in the figure, fix the heat-insulating plate 31 on the top surface of the ice-making mold 1, and fix the upper cover 41 on the outer shell 4; connect the evaporation tube 2 to an external refrigeration system so that the refrigerant flows through the evaporation tube 2, thereby completing the assembly. When the ice maker evaporator is in use, the refrigerant flows through the evaporation tube 2, and the evaporation tube 2 exchanges heat with the ice-making mold 1, causing the ice-making mold 1 to cool down, so that the water in the ice-making cavity 12 freezes quickly.

[0061] Embodiment 2

[0062] As Figure 9 shown in the figure, the present invention provides an ice maker evaporator, whose structure is basically the same as that of Embodiment 1, except that: the heat-insulating plate 31 is fixed on the bottom surface of the cover plate 3.

[0063] Through the above structural arrangement, the evaporation tube 2 is located between the heat-insulating plate 31 and the ice-making mold 1, which is beneficial to reducing the loss of cold quantity of the evaporation tube 2; after the cover plate 3 finishes squeezing the evaporation tube 2, it is not necessary to remove the cover plate 3, which is beneficial to improving the refrigeration effect.

[0064] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
