Description

Technical Field

[0001] This utility model relates to the field of ice cream machine technology, specifically to an 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 an evaporation component for an ice cream machine that facilitates ice cream demolding.

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

[0005] An evaporation assembly for an ice cream machine includes an aluminum profile extrusion body, a plastic shell, and an evaporation tube. The aluminum profile extrusion body forms at least two vertical heat-conducting walls, and an installation groove is formed between adjacent heat-conducting walls. The installation groove is open at both ends along its length. An ice tray is detachably installed in the installation groove. Adjacent heat-conducting walls are connected by a bottom wall. Each heat-conducting wall has a plurality of vertically arranged installation holes along its length, with an even number of installation holes. The evaporation tube is U-shaped and passes through one end of an adjacent installation hole to the other end. The outer circumference of the evaporation tube and the inner circumference of the installation hole are in contact for heat conduction. A receiving groove is formed inside the plastic shell. The receiving groove is open at both ends along its length and is adapted to the shape of the aluminum profile extrusion body. The aluminum profile extrusion body is inserted into the receiving groove from one end.

[0006] Furthermore, a first perforation is provided along the length direction between adjacent mounting holes in each heat-conducting wall.

[0007] The first perforation reduces the weight of the aluminum profile extrusion body, saving costs.

[0008] Furthermore, each heat-conducting wall has a second perforation along its length above the topmost mounting hole.

[0009] The second perforation reduces the weight of the aluminum profile extrusion body, saving costs.

[0010] Furthermore, the aluminum profile extrusion body forms three vertical heat-conducting walls. The bottom of the heat-conducting wall in the middle of the aluminum profile extrusion body is provided with a first positioning groove. The first positioning groove is set along the length direction of the aluminum profile extrusion body. The corresponding receiving groove protrudes to form a first positioning protrusion, which is inserted into the first positioning groove.

[0011] The first positioning protrusion and the first positioning groove cooperate to facilitate the assembly of the aluminum profile extrusion body and the plastic shell, and the aluminum profile extrusion body is not easy to shift left or right.

[0012] Furthermore, the bottom of the heat-conducting walls on both sides of the aluminum profile extrusion body is provided with a second positioning groove. The second positioning groove is set along the length direction of the aluminum profile extrusion body, and the corresponding receiving groove protrudes to form a second positioning protrusion, which is inserted into the second positioning groove.

[0013] The second positioning protrusion and the second positioning groove cooperate to facilitate the assembly of the aluminum profile extrusion body and the plastic shell, and the aluminum profile extrusion body is not easy to shift left or right.

[0014] Furthermore, hooks are provided on the top of both sides of the plastic shell. The hooks wrap around the top of the heat-conducting wall on the outside, and the hooks and the second positioning protrusion clamp the heat-conducting wall on the outside.

[0015] The hook and the second positioning protrusion cooperate to restrict the vertical displacement of the aluminum profile extrusion body.

[0016] Furthermore, a clearance notch is formed between the hook and the top surface of the heat-conducting wall located on the outer side.

[0017] The notch makes it easier to install the ice tray.

[0018] Furthermore, the ice tray includes a fixed plate and an ice bucket. The fixed plate has a placement cavity, and the bottom surface of the fixed plate has several annular protrusions facing downwards. The annular protrusions are hollow and form through holes that connect to the placement cavity. The ice bucket has a mold cavity, and the top of the ice bucket has an annular U-shaped flange. The top of the ice bucket is aligned and inserted into the through hole. The annular protrusions are inserted into the U-shaped flange, and the U-shaped flange clamps the annular protrusions. The mold cavity and the placement cavity are connected. The ice bucket is inserted into the mounting groove, and the fixed plate is placed on top of the heat-conducting wall.

[0019] Ice trays are low in manufacturing cost. The ice tray and the aluminum profile extrusion body are plugged together for easy installation and disassembly, making it convenient for users to clean the ice tray and more hygienic to use.

[0020] Furthermore, the bottom of the fixed plate and the top of the plastic shell abut against each other, the U-shaped flange is placed in the clearance notch, and the ice bucket only has one opposite side and bottom surface in contact with the aluminum profile extrusion body for heat conduction.

[0021] The ice bucket has a temperature difference only around its perimeter, preventing the ice bucket and ice cream from freezing together and making it easier to unmold the ice cream.

[0022] Furthermore, the mounting groove has a U-shaped cross-section, with the two corresponding heat-conducting walls set at an angle, and the ice bucket is set at an angle on the outside. After the ice bucket is inserted into the mounting groove, the two opposite sides of the ice bucket are respectively attached to the adjacent heat-conducting walls.

[0023] After the ice bucket is inserted into the mounting slot, it will naturally adhere to the heat-conducting wall under the action of gravity, ensuring efficient heat exchange.

[0024] This utility model features a plastic shell that reduces the exposed surface area of ​​the aluminum profile extrusion body, thereby improving the heat exchange efficiency of the evaporation assembly. The evaporator tube and the aluminum profile extrusion body are plugged into each other, with their circumferential surfaces in contact, providing a large heat conduction area. The ice tray is removable for easy cleaning. The aluminum profile extrusion body, plastic shell, evaporator tube, and ice tray are manufactured separately and then assembled, making manufacturing and assembly easy and resulting in low overall production costs.

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] Example 1, see Figure 1-6 As shown, an evaporation assembly for an ice cream machine includes an aluminum profile extrusion body 1, a plastic shell 3, an evaporation tube 2, and an ice tray 4.

[0033] The aluminum profile extrusion body 1 forms three vertical heat-conducting walls 11. An installation groove 10 is formed between adjacent heat-conducting walls 11, open at both ends along its length. The installation groove 10 has a U-shaped cross-section, and the sides of the corresponding two heat-conducting walls 11 are inclined inwards from top to bottom. Each heat-conducting wall 11 has several vertically arranged installation holes 12 along its length, with an even number of holes; in this embodiment, there are four installation holes 12. A first perforation 13 is provided between adjacent installation holes 12 within each heat-conducting wall 11 along its length. A second perforation 14 is provided above the uppermost installation hole 12 on each heat-conducting wall 11 along its length. A first positioning groove 15 is provided at the bottom of the middle heat-conducting wall 11, and second positioning grooves 16 are provided at the bottom of the heat-conducting walls 11 on both sides of the aluminum profile extrusion body 1. The first positioning groove 15 and the second positioning groove 16 are arranged along the length of the aluminum profile extrusion body 1. Adjacent heat-conducting walls 11 are connected by a bottom wall 17. A connecting countersunk hole 18 is provided on the bottom wall 17.

[0034] The evaporator tube 2 is U-shaped and extends from one end of an adjacent mounting hole 12 to the other. The outer circumference of the evaporator tube 2 and the inner circumference of the mounting hole 12 are in contact for heat conduction. In this embodiment, two evaporator tubes 2 are installed on each heat-conducting wall 11. The input end of each evaporator tube 2 is connected to one end of the refrigeration system 8, and the output end of each evaporator tube 2 is connected to the other end of the refrigeration system 8.

[0035] The plastic shell 3 has a receiving groove 30 inside, which is open at both ends along its length. The receiving groove 30 is adapted to the shape of the aluminum profile extrusion body 1. The receiving groove 30 protrudes upward to form a first positioning protrusion 31 corresponding to the first positioning groove 15, and protrudes upward to form a second positioning protrusion 32 corresponding to the second positioning groove 16. Hooks 33 are provided on the top of both sides of the plastic shell 3. The plastic shell 3 has a hollow part 34 corresponding to the connecting countersunk hole 18, which facilitates the screw to pass through the connecting countersunk hole 18 and the hollow part 34 to connect and fix to the fixing seat 91 of the ice cream machine bottom shell 9.

[0036] The aluminum profile extrusion body 1 is inserted into the receiving groove 30 from one end. The first positioning protrusion 31 is inserted into the first positioning groove 15, and the second positioning protrusion 32 is inserted into the second positioning groove 16. The hook 33 wraps around the top of the outer heat-conducting wall 11, and the hook 33 and the second positioning protrusion 32 clamp the outer heat-conducting wall 11 tightly. A clearance notch 35 is formed between the hook 33 and the top surface of the outer heat-conducting wall 11.

[0037] The ice tray 4 includes a fixed plate 5 and an ice bucket 6. The fixed plate 5 has a placement cavity 51. The bottom surface of the fixed plate 5 has several annular protrusions 52. The annular protrusions 52 are hollow to form through holes 50, which connect to the placement cavity 51. The ice bucket 6 has a mold cavity 60. The top of the ice bucket 6 has an annular U-shaped flange 61. The top of the ice bucket 6 is aligned and inserted into the through hole 50. The annular protrusions 52 are inserted into the U-shaped flange 61, and the U-shaped flange 61 clamps the annular protrusions 52. The mold cavity 60 and the placement cavity 51 are connected.

[0038] The ice bucket 6 is inserted into the mounting slot 10, and the fixing plate 5 is placed on top of the heat-conducting wall 11. Specifically, the bottom of the fixing plate 5 abuts against the top of the plastic shell 3, the U-shaped flange 61 is placed within the clearance notch 35, and only one opposite side and the bottom surface of the ice bucket 6 are in contact with the aluminum profile extrusion body 1 for heat conduction. The outer side of the ice bucket 6 is inclined, and after the ice bucket 6 is inserted into the mounting slot 10, the opposite two sides of the ice bucket 6 are respectively in close contact with the adjacent sides of the heat-conducting wall 11.

[0039] During operation, liquid ice cream is injected into the mold cavity 60, and a sealing cap 7 is placed in the placement cavity 51 to seal the placement cavity 51. The refrigerant in the ice cream machine's refrigeration system 8 flows through the evaporator pipe 2, and the refrigerant carries away the heat from the liquid ice cream through the evaporator pipe 2, the aluminum profile extrusion body 1, and the ice bucket 6, causing the liquid ice cream to cool and solidify. During this process, the plastic shell 3 reduces the contact area between the aluminum profile extrusion body 1 and the outside environment, thereby improving the cooling effect on the ice bucket 6. Because the ice tray 4 is removable, it is easy to remove the ice tray 4 and then the ice cream. The temperature difference on the side of the ice bucket 6 prevents the ice cream and the ice bucket 6 from freezing together, making it easier for the ice cream to detach from the mold cavity 60. 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 4.
