[0002] Existing vending machines and other equipment generally require built-in refrigeration components to control the internal temperature of the vending machine, so that the food inside is less likely to spoil.

[0003] Existing refrigeration components typically include compressors, evaporators, condensers, and other parts, all of which are directly fixed to the main support frame of the vending machine. This means that when problems such as damage to the refrigeration components occur, maintenance can only be performed by disassembling all related components one by one. This disassembly is cumbersome, and the limited space in the vending machine further restricts maintenance, making installation and disassembly extremely difficult and troublesome.

[0004] Moreover, since it is directly fixed to the vending machine, the compressor and other components generate a lot of heat during operation, which is also conducted into the entire device, affecting the cooling effect of the device. Utility Model Content

[0038] An upper bending support frame 52 is fixed on the bottom plate of the main housing 10 where the first water receiving tank 50 is located. Multiple connecting slots are formed on the top plate of the upper bending support frame 52. The first water receiving tank 50 is located directly below the top plate of the upper bending support frame 52. An upper connecting plate is provided in the middle of the upper bending support frame 52. The upper connecting plate is located above the first water receiving tank 50 and covers the top of the first water receiving tank 50. Multiple lower connecting slots are also formed on the upper connecting plate, which can insert the upper and lower parts of the water absorption sheet (omitted in the attached figure) into the corresponding connecting slots and lower connecting slots. Its bottom extends into the first water receiving tank 50. A drain outlet 54 extending to the left is formed in the middle of the left side plate of the first water receiving tank 50. The drain outlet 54 is located directly above the second water receiving tank 60.

[0039] Furthermore, a downwardly extending drain connector 111 is formed in the middle between the bottom end of the inclined plate portion 11 and the rear end of the front extension plate portion 12. The bottom end of the drain connector 111 is connected to a drain pipe 118, and the outlet end of the drain pipe 118 extends into the first water receiving tank 50.

[0040] The outlet end of the condenser 40 is connected to the inlet end of the dryer filter through a connecting pipe, and the outlet end of the dryer filter is connected to one end of the capillary tube 80. The dryer filter is fixed on the corresponding side plate of the upper bending support frame 52.

[0041] A fan guide housing 57 is fixed to the rear of the top plate of the upper support frame 52. At least one fan 59 is fixed to the rear wall of the fan guide housing 57, with its air inlet facing the through hole of the rear wall of the fan guide housing 57. The air inlet at the front of the fan guide housing 57 faces the rear of the evaporator 70.

[0042] Both the inclined plate portion 11 and the front extension plate portion 12 have upwardly extending bent edges formed on their left and right sides. The front end of the front extension plate portion 12 has an upwardly extending front side portion formed at its front end. The left and right ends of the front side portion are formed together with the front ends of the bent edges on both sides.

[0043] A liquid guide plate 55 is welded and fixed to the bottom plate of the fan guide housing 57. The front part of the liquid guide plate 55 is located below the bottom surface of the middle part of the evaporator 70 and close to the bottom surface of the evaporator 70. The front end of the liquid guide plate 55 is formed with a downward and forward inclined liquid guide plate portion 56, the bottom end of which faces the top surface of the front extension plate portion 12. A bending piece is fixed to the top surface of the upper inclined plate 112, and the front bending plate portion of the bending piece is fixed to the rear wall plate of the fan guide housing 57. The bending piece improves the fixing firmness of the fan guide housing 57.

[0044] The top surface of the bottom plate of the inner shell is fixed with a fixed chassis 5, and the compressor assembly 30, condenser 40, first water receiving tank 50, second water receiving tank 60 and upper bending support frame 52 are fixed on the top surface of the bottom plate of the fixed chassis 5.

[0045] A temperature sensing bulb 9 is fixed to the outer wall of the middle part of the second connecting pipe 2 by a clamp.

[0046] In this embodiment, the compressor assembly 30 operates, introducing high-temperature, high-pressure refrigerant gas into the condenser 40. Meanwhile, the suction fan at the outlet channel 15 draws external air through the central channel, allowing it to pass through the condenser 40 for heat exchange before entering the main casing 10. This causes the refrigerant in the condenser 40 to dissipate heat, transforming the high-temperature, high-pressure gas into a high-temperature, high-pressure liquid. After being dried by a dryer filter, the liquid enters the expansion valve 80, becoming a low-temperature, low-pressure liquid before entering the evaporator 70. The fan 59 operates, causing external gas to pass through the front of the evaporator 70, exchange heat, and then exit through the cooling outlet channel 16. At this time, the refrigerant in the evaporator 70 absorbs heat, cooling the incoming gas. The refrigerant in the evaporator 70, after absorbing heat, becomes a low-temperature, low-pressure liquid before entering the compressor assembly 30.

[0047] The second connecting pipe 2 is equipped with a temperature sensor 9, which can sense the temperature of the refrigerant at the second connecting pipe 2. When the temperature is too high, the opening of the expansion valve 80 is automatically reduced, thereby lowering the temperature of the refrigerant coming out of the evaporator 70. When the temperature is too low, the opening of the expansion valve 80 is automatically increased, thereby raising the temperature of the refrigerant coming out of the evaporator 70 to meet the user's needs.

[0048] Meanwhile, during operation, the condensate in the evaporator 70 enters between the bottom end of the inclined plate 11 and the rear end of the front extension plate 12, and then enters the first water receiving tank 50 through the drain connector 111 and drain pipe 118. The water is then absorbed by the absorbent plates. At this time, external air enters the main casing 10 through the condenser 40, blowing air onto the absorbent plates to rapidly evaporate the water, thus significantly reducing the condensate in the first water receiving tank 50. If the condensate in the first water receiving tank 50 continues to increase, its… The refrigerant gas flows into the second water receiving tank 60 through the drain outlet 54. The middle part of the first connecting pipe 1 is located in the second water receiving tank 60, with its bottom surface close to or near the top surface of the bottom plate of the second water receiving tank 60. The refrigerant gas flowing inside is high-temperature and high-pressure gas, which exchanges heat with the water in the second water receiving tank 60, thereby causing the water in the second water receiving tank 60 to evaporate. At the same time, it also reduces the temperature of the refrigerant in the first connecting pipe 1, resulting in better heat dissipation and efficiency when flowing in the subsequent condenser 40, thus achieving energy-saving effect.

[0049] In this embodiment, all refrigeration components are installed in the main housing 10. However, when maintenance is required, the main housing 10 can be removed from the vending machine and placed outside for maintenance, which is very convenient and effective.

[0050] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model, and the patent protection scope of the present utility model should be defined by the claims.
