[0003] Vending machines typically have refrigeration or freezing functions, using a refrigeration module to cool the vending machine cabinet. This module typically consists of a compressor, evaporator, and condenser. The condenser cools the high-temperature, high-pressure refrigerant gas into a low-temperature, low-pressure liquid, which then reenters the evaporator for heat absorption and cooling.

[0004] Existing refrigeration modules are typically integrated into a single, standalone unit, integrating the compressor, evaporator, and condenser. This facilitates installation and maintenance. However, due to limited maintenance space, these modules must be completely removed from the vending machine for repair. This results in lengthy disassembly and assembly times, increased labor intensity, and reduced efficiency. Furthermore, the integrated design makes the module bulky and heavy, making it difficult to move and remove, increasing maintenance complexity and costs.

[0005] In view of this, it is necessary to propose a new technical solution to solve the above technical problems. Summary of the Invention

[0037] Example 1

[0038] See Figure 1-5 As shown, the refrigeration module includes a condenser 1, a compressor 2, an evaporator 3 and an installation box 4 installed in the vending machine. The condenser 1 and the compressor 2 are respectively installed in the installation box 4, the evaporator 3 is installed on the top of the installation box 4, and a sliding mechanism 5 is provided at the bottom of the installation box 4.

[0039] When repairing the refrigeration module, the sliding mechanism 5 can be used to directly drag the refrigeration module out of the box of the vending machine. During installation, the refrigeration module can also be directly pushed into the box of the vending machine, which reduces the labor intensity of the staff, makes installation and maintenance more convenient, improves work efficiency, has a simple structure, and is highly practical.

[0040] The sliding mechanism 5 includes at least one pulley, which is installed at the bottom of the installation box 4 and slides on the box body of the vending machine.

[0041] like Figure 1-3As shown, as a preferred embodiment, the number of the pulley in this embodiment is one, and the pulley is arranged in the middle position of the rear end of the installation box 4.

[0042] In other specific embodiments, there may be two, three or four pulleys, such as Figure 4 、 Figure 5 As shown, when there are two pulleys, the two pulleys are respectively arranged at the two sides of the rear end of the installation box 4. When there are three pulleys, one pulley is arranged at the middle position of the rear end of the installation box 4, and the other two pulleys are arranged at the two sides of the installation box 4. Alternatively, two pulleys can be respectively arranged at the two sides of the rear end of the installation box 4, and one pulley can be arranged at the middle position of the installation box 4. When there are four pulleys, the four pulleys are respectively arranged at the four corners of the installation box 4.

[0043] In a further specific embodiment, the installation box 4 is provided with a handle 41 for dragging the entire refrigeration module. Figure 3 As shown, the handle 41 is provided at the front end of the installation box 4. As a preferred embodiment, the handle 41 of this embodiment is provided at the top wall on the inner side of the installation box 4, between the cover plate 42 and the dustproof net 44, so as to improve space utilization and reduce the volume of the refrigeration module. Although in other specific embodiments, the handle 41 can also be provided on the top of the installation box 4, such a provision will inevitably increase the volume of the entire refrigeration module, and also means that the position inside the vending machine needs to be adjusted. By providing the handle 41, when maintenance is required, the front end of the installation box 4 is lifted by the handle 41, and the rear end is supported by the rollers, so that the refrigeration module can be pulled out like a trailer. One person can complete the action of moving the refrigeration module, reducing the difficulty and cost of maintenance.

[0044] In a further specific embodiment, a cover plate 42 is installed at the front end of the installation box 4 , a connector 43 is provided between the cover plate 42 and the installation box 4 , and the cover plate 42 is installed at the front end of the installation box 4 through the connector 43 .

[0045] It should be noted that when the cover 42 is installed at the front end of the installation box 4, the cover 42 is actually located at the back of the vending machine. Through the setting of the connecting piece 43, the cover 42 can be more easily removed from the installation box 4, with a simple structure and convenient maintenance.

[0046] In a further specific embodiment, the connecting member 43 includes a hook 431 and a mounting seat 432, wherein the hook 431 is mounted on the cover plate 42, the mounting seat 432 is mounted on the installation box 4, and the hook 431 is suspended on the mounting seat 432. Figure 1-3As shown in the figure, as a preferred embodiment, the hook 431 of this embodiment is perpendicular to the cover plate 42 and has a mounting hole, through which it is hung on the mounting seat 432 on the installation box 4. When removing the cover plate 42, the cover plate 42 can be removed by simply lifting the cover plate 42 upward to separate the mounting hole from the mounting seat 432.

[0047] like Figure 4 、 Figure 5 As shown, in other specific embodiments, the connecting member 43 may also be a luggage buckle, that is, the hook 431 is hook-shaped, and a connecting shaft is provided on the mounting base 432. Under the influence of gravity, the hook 431 is suspended from the connecting shaft. In this way, when removing the cover 42, the hook 431 can be separated from the connecting shaft.

[0048] The inner side of the cover plate 42 is provided with a heat-insulating layer 421. The heat-insulating layer 421 is provided to keep the temperature inside the installation box 4 warm. It should be noted that the heat-insulating layer 421 of this embodiment is made of polyurethane material.

[0049] In a further embodiment, a dust screen 44 is provided between the cover plate 42 and the condenser 1. In a further embodiment, a condensing fan 11 is provided in the installation box 4, the dust screen 44 is provided on the outside of the condenser 1, and the condensing fan 11 is provided on the inside of the condenser 1.

[0050] The condenser 1 will inhale a large amount of air during operation, and the dust in the air will adhere to the surface of the condenser 1, affecting its heat dissipation effect, thereby reducing the refrigeration efficiency. In this embodiment, a dustproof net 44 is provided at the condenser 1 to prevent the entry of dust. It is only necessary to clean the dustproof net 44 regularly to ensure the heat dissipation performance of the condenser 1, ensure the stable operation of the refrigeration system, and extend the service life of the equipment. The cover plate 42 in the prior art is fixed to the mounting box 4 by means of locking screws. Although the structural stability is strong, the disassembly and assembly are cumbersome. The use of the connector 43 of this embodiment makes it simple and quick to disassemble the cover plate 42, and it is more convenient to remove dust from the dustproof net 44.

[0051] Example 2

[0052] The vending machine includes a housing, a refrigeration module disposed within the housing, and a bottom portion of the housing having a chute or reinforcement beam configured to engage with the sliding mechanism 5. The vending machine of this embodiment may include a chute at the bottom portion of the housing to guide the sliding of the sliding mechanism 5, or may include a reinforcement beam to reinforce the area engaging the sliding mechanism 5 to prevent damage to the housing caused by repeated sliding of the sliding mechanism 5 within the housing. This embodiment includes all the technical features and effects of Example 1 and will not be further elaborated.

[0053] Descriptions such as "specific examples" or "some examples" mean that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention.
