Moreover, multiple freezing areas are arranged, and the freezing area is cooled by refrigeration air duct, and cold air is sent to multiple freezing areas through refrigeration air duct, multiple freezing areas are refrigerated, and independent temperature zones can be formed in freezing area, different temperatures are controlled, multiple freezing temperature zones are further provided, and more freezing preservation environment of goods is provided.

[0029] In combination with Figure 2 , Figure 3 And Figure 4 As shown in the figure, the refrigeration air duct 30 includes:

[0030] Freezing space 31, and the freezing evaporator 22 is located in the freezing space 31;

[0031] First air duct 32, and the first end of the first air duct 32 leads to the freezing space 31;

[0032] An air supply air duct 33 is in communication with the freezing space 31, and the air supply air duct 33 is in communication with the plurality of freezing zones 12 respectively;

[0033] A return air duct 34 is in communication with the first air duct 32, and the freezing zone 12 is in communication with the return air duct 34.

[0034] The freezing air duct 30 for circulating cold air is formed by the freezing space 31, the first air duct 32, the air supply air duct 33, and the return air duct 34, so that the air flow can be circulated to cool, the energy consumption is reduced, and the cooling efficiency is increased. Referring to Figure 3 The air flow enters the freezing space 31 from the first air duct 32, exchanges heat with the freezing evaporator 22 in the freezing space 31 to be cooled, the low-temperature cold air enters the air supply air duct 33 from the freezing space 31, and the cold air in the air supply air duct 33 enters the freezing zone 12 respectively to be cooled. The air flow in the freezing zone 12 flows back to the first air duct 32 from the return air duct 34, so that a circulating air flow is formed. The structure of the freezing air duct 30 is simple, and the cooling demand of the plurality of freezing zones is considered, and the cooling efficiency is high.

[0035] The vending cabinet further comprises a return air fan 40 arranged in the freezing air duct 30, and the return air fan 40 is arranged at the second end position of the first air duct 32.

[0036] In order to further increase the air flow circulation, the return air fan 40 is additionally arranged at the second end position of the first air duct 32, and the return air fan 40 can suck the air in the return air duct 34 into the first air duct 32, and blow the air flow in the first air duct 32 into the freezing space 31.

[0037] In the embodiment, the return air fan 40 is a centrifugal fan, and the return air fan 40 is located at the bottom of all the freezing zones 12, and the air flow passes through all the freezing zones 12 and then passes through the return air fan 40.

[0038] The centrifugal fan has an advantage over other fans in that the centrifugal fan can converge the air flow dispersed in the return air duct 34 and blow the air flow to the first air duct 32. Since the cold air has a large density and will move downward, the air flow passing through the plurality of freezing zones 12 from top to bottom is more energy-saving, and therefore the return air fan 40 is arranged at the bottom to reduce the output power of the fan and reduce the energy consumption.

The freezing space 31 is arranged at the top of the cabinet, so that the cold air passing through the freezing space for heat exchange and temperature reduction can enter the multiple vertically arranged freezing areas 12 from the air supply air duct 33 more efficiently, further reducing energy consumption. Moreover, the freezing space 31 is arranged at the top of the cabinet, facilitating maintenance, and does not occupy the internal space of the cabinet, so that the structural space of the freezing area is larger.

[0041] Preferably, a foamed partition plate 50 is arranged between the multiple freezing areas 12. The foamed partition plate 50 is arranged between the freezing areas to intercommunicate the cold energy, so that the temperature of each freezing area is independent, and the multiple freezing areas can be managed separately to adapt to food or goods with different temperature requirements. The foamed partition plate also has a certain structural strength and can be used as a side wall of the freezing area, achieving one thing with two purposes. In the embodiment, the number of the freezing areas 12 is two, and the number of the foamed partition plates 50 is one and arranged between the two freezing areas.

The first air duct 32 and the air supply air duct 33 are thermally insulated by a thermal insulation layer or a foamed partition plate, so that the cold air in the air supply air duct can be kept at a low temperature, increasing the refrigeration efficiency.

[0044] In order to further increase the refrigeration efficiency of the freezing area, in the embodiment, an air inlet fan 60 is arranged in the freezing space 31, the air inlet fan 60 is arranged adjacent to the air supply air duct 33, and the air inlet fan 60 is used to blow cold air towards the air supply air duct 33.

[0045] Preferably, a thermal insulation layer is arranged between the refrigeration area 11 and all the freezing areas 12.

[0046] The thermal insulation layer can use a foamed partition plate or a thermal insulation sponge. The refrigeration area and the freezing area are thermally insulated by the foamed outer plate of the refrigerator and the foamed partition plate inside, preventing the leakage and intercommunication of the cold energy in the cabinet, and achieving heat preservation and thermal insulation of the cabinet.

[0047] The refrigeration evaporator 21 is arranged at the top of the cabinet 10, and the refrigeration evaporator 21 and the freezing evaporator 22 are arranged in thermal insulation.

[0048] The refrigeration evaporator 21 and the freezing evaporator 22 are arranged together at the top of the cabinet, facilitating centralized maintenance and replacement. In the embodiment, part of the structure and control components of the refrigeration system are arranged in the mechanical room at the top of the cabinet. See Figure 2 In the mechanical room, the main control board 23 of the vending system, the compressor 24, the condenser 25, and other supporting devices are arranged.

The condenser is arranged on the cabinet mechanical room, and the refrigeration evaporator and the freezing evaporator are arranged above the cabinet. The compressor and the condenser are connected to two sets of evaporators through a shunt, and the cabinet uses a single refrigeration system with "one-to-two". The refrigeration system is cooled through the freezing air duct to divide the upper and lower freezing rooms.

[0050] In the embodiment, there are three temperature zones in the cabinet, see Figure 1 The left side is a refrigeration area of 0-10℃, and the right side is two freezing areas of -5-5℃. The three temperature zones in the cabinet can provide refrigeration and freezing preservation environments at the same time.

[0051] Of course, there can be other partitions, see Figure 5 The left side is two refrigeration areas distributed above and below, and the right side is two freezing areas distributed above and below. Since the temperature requirement of the refrigeration area is lower, the two refrigeration areas can be interconnected and maintain one temperature.
