Description

Technical Field

[0001] This utility model relates to the field of ice cream machine technology, specifically to an assembled evaporation component for an ice cream machine. Background Technology

[0002] Existing home ice cream makers freeze ice cream into shape using a refrigeration system. Specifically, evaporation tubes are coiled around the outer perimeter of each ice cube tray, as disclosed in Chinese patent CN119617713A. In this evaporation assembly, the tubes surround the outer and bottom surfaces of the ice cube tray. However, the exposed tubes reduce heat exchange efficiency, and the small actual contact area between the tubes and the ice cube tray results in low heat exchange efficiency. Furthermore, the ice cream tends to freeze solid with the tray, making it difficult to unmold. The integrated nature of the ice cube tray and tube assembly also makes cleaning difficult. Utility Model Content

[0003] The purpose of this invention is to provide a low-cost, modular evaporation component for ice cream machines.

[0004] The purpose of this utility model is achieved as follows.

[0005] An assembled evaporation component for an ice cream machine includes a first aluminum profile module, a first plastic module, and a second plastic module. The first aluminum profile module has an L-shaped cross-section and includes a vertical part and a horizontal part. The outer side of the vertical part of the first aluminum profile module has several first semi-circular holes along the height direction, and the inner side of the first plastic module has several second semi-circular holes along the height direction. Two first aluminum profile modules are joined together at their horizontal parts to form an installation groove. The installation groove is open at both ends along its length direction. An ice tray is detachably installed in the installation groove. The vertical part and the first plastic module are fitted together and fastened by connectors. The corresponding first and second semi-circular holes are joined together to form an installation hole. An evaporation tube is sandwiched in the installation hole. The second plastic module has a receiving groove. After the first aluminum profile module and the first plastic module are assembled, they are limited and fixed in the receiving groove.

[0006] Furthermore, on the side of the vertical part away from the horizontal part, a first clearance groove is provided between two adjacent first semicircular holes along the height direction, and the corresponding first plastic module is provided with a first protrusion. The first protrusion is inserted into the first clearance groove, and the first semicircular hole and the second semicircular hole are aligned and closed.

[0007] The first clearance groove and the first protrusion are positioned in a concave-convex manner to facilitate the assembly of the first aluminum profile module and the first plastic module, restrict the vertical displacement of the two, and make the first semi-circular hole and the second semi-circular hole easier to fix the evaporator tube.

[0008] Furthermore, the vertical part has a first fastening countersunk hole from one side of the horizontal part to the other side, and the corresponding first plastic module has a first screw hole. The connector is a screw, which passes through the first fastening countersunk hole and the first screw hole for threaded connection, and the screw nut is recessed into the first fastening countersunk hole.

[0009] The first aluminum profile module and the first plastic module are fastened with screws to limit their horizontal displacement. The first fastening countersunk hole design prevents the screws from interfering with the assembly and disassembly of the ice grid.

[0010] Furthermore, the vertical part has a second clearance groove above the first semi-circular hole at the highest position, and a third clearance groove is provided corresponding to the first plastic module. The second clearance groove and the third clearance groove are joined together to form the first hollow hole.

[0011] The first perforation reduces the overall weight of the evaporation unit, saving materials and reducing costs.

[0012] A recessed abutment is formed at the connection between the bottom of the vertical part and the horizontal part. The second plastic module has a protruding abutment. The protruding abutment and the recessed abutment fit together. The bottom of the first plastic module sits on the protruding abutment.

[0013] The two sides abutting protrusions and abutting recesses fit together to restrict the displacement of the first aluminum profile module and the first plastic module in the horizontal direction of the second plastic module.

[0014] Furthermore, the second plastic module has a hook on the top of its side wall, which wraps around the top of the first plastic module, and the hook and the abutting protrusion limit the first plastic module vertically.

[0015] The second plastic module restricts the vertical displacement of the first aluminum profile module and the first plastic module.

[0016] Furthermore, a clearance gap is formed between the top surface of the hook and the vertical part.

[0017] The notch design allows for easy installation of the ice tray into the mounting slot.

[0018] Furthermore, the bottom of the receiving slot is provided with a groove, and the horizontal parts of the two first aluminum profile modules are embedded in the groove.

[0019] The groove facilitates the horizontal installation of the first aluminum profile module and guides the horizontal end faces to align and come together.

[0020] Furthermore, it also includes a second aluminum profile module, which includes a vertical part and a horizontal part with the same shape as the first aluminum profile module. The vertical part of the second aluminum profile module is provided with a second screw hole, and the vertical part of the first aluminum profile module is provided with a first fastening countersunk hole. The first fastening countersunk hole and the second screw hole are aligned and fixed by screw connection. The first semi-circular hole of the second aluminum profile module and the first semi-circular hole of the first aluminum profile module are aligned and closed to form the mounting hole. The three first aluminum profile modules and one second aluminum profile module are spliced ​​together to form two mounting grooves arranged side by side.

[0021] The second aluminum profile module, in conjunction with the first aluminum profile module, allows the evaporator assembly to be fitted with multiple side-by-side mounting slots, thus enabling it to be adapted to ice trays with larger capacities.

[0022] Furthermore, a second fastening countersunk hole is provided at the bottom of the horizontal part, and a hollow part is provided on the second plastic module corresponding to the second fastening countersunk hole.

[0023] The second fastening countersunk hole facilitates the connection and fixation of the evaporation assembly and the ice cream machine.

[0024] The evaporator assembly of this invention is composed of multiple modules, resulting in low overall manufacturing cost. The first aluminum profile module and the evaporator tube facilitate heat exchange with the refrigerant inside the evaporator tube. The first and second plastic modules reduce the weight and cost of the evaporator assembly, and reduce the exposed surface area of ​​the evaporator assembly, thereby improving the heat exchange efficiency with the ice tray.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] Example 1, see Figure 1-5As shown, an assembled evaporation assembly for an ice cream machine includes a first aluminum profile module 1, a second aluminum profile module 2, a first plastic module 3, a second plastic module 4, an evaporation tube 5, and an ice tray 8.

[0032] The first aluminum profile module 1 has an L-shaped cross-section and includes a vertical portion 11 and a horizontal portion 12. The outer side of the vertical portion 11 of the first aluminum profile module 1 has several first semi-circular holes 13 along the height direction. On the side of the vertical portion 11 away from the horizontal portion 12, a first clearance groove 14 is provided between two adjacent first semi-circular holes 13 along the height direction. A second clearance groove 15 is provided above the highest first semi-circular hole 13 on the vertical portion 11. An abutment recess 16 is formed at the connection between the bottom of the vertical portion 11 and the horizontal portion 12. The vertical portion 11 of the first aluminum profile module 1 has a first fastening countersunk hole 17 extending from one side of the horizontal portion 12 to the other. A second fastening countersunk hole 18 is provided at the bottom of the horizontal portion 12.

[0033] The second aluminum profile module 2 includes a vertical part 11 and a horizontal part 12 with the same shape as the first aluminum profile module 1. The only difference between the second aluminum profile module 2 and the first aluminum profile module 1 is that a second screw hole 20 is provided at the corresponding first fastening countersunk hole 17 position.

[0034] The inner side of the first plastic module 3 (i.e. the side facing the vertical part 11) is provided with a plurality of second semi-circular holes 31 along the height direction. The first plastic module 3 is provided with a first protrusion 32, a first screw hole 33 and a third clearance groove 34 facing the vertical part 11.

[0035] See Figure 3 As shown, in this embodiment, three first aluminum profile modules 1, one second aluminum profile module 2, and two first plastic modules 3 are assembled. Specifically, the two first aluminum profile modules 1 are joined together by their horizontal portions 12 to form a mounting groove 10. The mounting groove 10 is open at both ends in the length direction. The second aluminum profile and the right first aluminum profile module 1 abut against each other by their vertical portions 11. Screws pass through the second fastening countersunk hole 18 and the second screw hole 20 for threaded connection. The first semi-circular holes 13 of the first aluminum profile module 1 and the second aluminum profile module 2 are aligned and joined together to form a mounting hole 21. The first clearance grooves 14 of the first aluminum profile module 1 and the second aluminum profile module 2 are aligned and joined together to form a second hollow hole 22. The second clearance grooves 15 of the first aluminum profile module 1 and the second aluminum profile module 2 are aligned and joined together to form a first hollow hole 19. The abutment recesses 16 of the first aluminum profile module 1 and the second aluminum profile module 2 are joined together to form a positioning groove 23. This allows three first aluminum profile modules 1 and one second aluminum profile module 2 to be spliced ​​together to form two side-by-side mounting slots 10. During the splicing process, the evaporator tube 5 is clamped in the mounting hole 21. In this embodiment, one evaporator tube 5 is inserted back and forth through the mounting hole 21 in the same vertical direction along the length of the mounting slot 10.

[0036] The first aluminum profile module 1 located on both sides is assembled with the first plastic module 3. Specifically, the vertical portions 11 of the first plastic module 3 and the first aluminum profile module 1 are fitted together and fastened by connectors, that is, the first protrusion 32 is inserted into the first relief groove 14, and the first semi-circular hole 13 and the second semi-circular hole 31 are aligned and closed to form the mounting hole 21. The second relief groove 15 and the third relief groove 34 are closed to form the first hollow hole 19. The connector is a screw, which passes through the first fastening countersunk hole 17 and the first screw hole 33 for threaded connection, and the screw head is recessed into the first fastening countersunk hole 17.

[0037] The second plastic module 4 is provided with a receiving groove 41, which is open at both ends along its length. The shape of the receiving groove 41 is adapted to the shape of the first aluminum profile module 1, the second aluminum profile module 2, and the first plastic module 3 after assembly. The three first aluminum profile modules 1, one second aluminum profile module 2, and two first plastic modules 3 are assembled and confined within the receiving groove 41. Specifically, the bottom of the receiving groove 41 is provided with two grooves 42, and the horizontal portions 12 of the two first aluminum profile modules 1 and the horizontal portions 12 of the first aluminum profile modules 1 and the second aluminum profile module 2 are embedded in the grooves 42. The second plastic module 4 is provided with an abutting protrusion 43, which engages with an abutting recess 16, and the bottom of the first plastic module 3 rests on the abutting protrusion 43. The top of the side wall of the second plastic module 4 is provided with a hook 44, which wraps around the top of the first plastic module 3, and the hook 44 and the abutting protrusion 43 limit the first plastic module 3 vertically. A clearance notch 45 is formed between the top surface of the hook portion 44 and the vertical portion 11. A positioning protrusion 47 is provided between the two grooves 42. The second plastic module 4 has a hollow portion 46 corresponding to the second fastening countersunk hole 18.

[0038] Three first aluminum profile modules 1, one second aluminum profile module 2, and two first plastic modules 3 are assembled. The side end of the second plastic module 4 is inserted into the receiving groove 41. The second plastic module 4 limits and fixes the three first aluminum profile modules 1, one second aluminum profile module 2, and two first plastic modules 3. Among them, the positioning protrusion 47 is inserted into the positioning groove 23.

[0039] The inner side of the first plastic module 3 is provided with several second semi-circular holes 31 along the height direction. An ice grid 8 is detachably provided in the mounting groove 10. The vertical part 11 and the first plastic module 3 are fitted together and fastened by the connector. The corresponding first semi-circular holes 13 and second semi-circular holes 31 are joined together to form a mounting hole 21. The second plastic module 4 is provided with a receiving groove 41. After the first aluminum profile module 1 and the first plastic module 3 are spliced ​​together, they are limited and fixed in the receiving groove 41.

[0040] See Figure 5As shown, an ice cream machine has an upwardly extending fixing seat 71 on the bottom shell 7. The fixing seat 71 is inserted into the hollow part 46. The screw passes through the second fastening countersunk hole 18 and is connected and fixed to the fixing seat 71, that is, the evaporation component is fixed on the bottom shell 7, so as to prevent the evaporation component from being removed when the ice tray 8 is removed.

[0041] The ice tray 8 includes a fixed plate 81 and an ice bucket 9. The fixed plate 81 has a placement cavity 82. The bottom surface of the fixed plate 81 has several annular protrusions 83. The annular protrusions 83 are hollow and form through holes that connect to the placement cavity 82. The ice bucket 9 has a mold cavity 90. The top of the ice bucket 9 has an annular U-shaped flange 91. The top of the ice bucket 9 is aligned and inserted into the through hole. The annular protrusions 83 are inserted into the U-shaped flange 91. The U-shaped flange 91 clamps the annular protrusions 83. The mold cavity 90 and the placement cavity 82 are connected.

[0042] The ice bucket 9 is inserted into the through hole, and the fixing plate 81 is placed on top of the second plastic module 4. Specifically, the bottom of the fixing plate 81 abuts against the top of the second plastic module 4, the U-shaped flange 91 is placed in the clearance notch 45, and only one opposite side and the bottom surface of the ice bucket 9 are in contact with the vertical part 11 and the horizontal part 12 for heat conduction. The outer side of the ice bucket 9 and the side wall of the mounting groove 10 are both inclined. After the ice bucket 9 is inserted into the mounting groove 10, the opposite two sides of the ice bucket 9 are in close contact with the sides of the vertical part 11.

[0043] During operation, liquid ice cream is injected into the mold cavity 90, and a sealing cap 84 is placed in the placement cavity 82, sealing the placement cavity 82. The refrigerant in the ice cream machine's refrigeration system flows through the evaporator pipe 5, and the refrigerant carries away the heat from the liquid ice cream through the evaporator pipe 5, the first aluminum profile module 1, the second aluminum profile module 2, and the ice bucket 9, causing the liquid ice cream to cool and solidify. During this process, both the first plastic module 3 and the second plastic module 4 reduce the contact area between the first aluminum profile module 1 and the second aluminum profile module 2 and the outside environment, thereby improving the cooling effect on the ice bucket 9. Because the ice tray 8 is removable, it is easy to remove the ice tray 8 and then the ice cream. The temperature difference on the side of the ice bucket 9 prevents the ice cream and the ice bucket 9 from freezing together, making it easier for the ice cream to detach from the mold cavity 90. The ice cream is less likely to break or crumble during demolding. After the ice cream is removed, the user can easily clean the ice tray 8.

[0044] See appendix Figure 6 As shown in Embodiment 2, the difference from Embodiment 1 is that only one mounting slot 10 is provided. Specifically, it is composed of two first aluminum profile modules 1, two first plastic modules 3, and one second plastic module 4. The accommodating cavity of the second plastic module 4 is adapted to the shape of the first aluminum profile module 1 and the first plastic module 3 after assembly.
