The second cavity 12 is provided with a second evaporation cavity 113 which separates the first cavity 111 into a first evaporation cavity 111 and a first thawing cavity 112 which are arranged transversely. A first partition plate 123 is provided between the first evaporation chamber 111 and the second thawing chamber 122, a first evaporator 23 is provided in the first evaporation chamber 111, a second evaporator 33 is provided in the second evaporation chamber 121, a first air inlet 114 is provided on one side of the first partition plate 113, and a first air outlet 115 is provided on the opposite side, a first fan (the first fan is not shown in the figure) is provided in the first evaporation chamber 111 for driving the airflow to circulate between the first thawing chamber 112 and the first evaporation chamber 111 through the first air inlet 114 and the first air outlet 115, and a second fan (the second fan is not shown in the figure) is provided in the second evaporation chamber 121 for driving the airflow to circulate between the second thawing chamber 122 and the second evaporation chamber 121 through the second air inlet 124 and the second air outlet 125.

[0024] See also Figure 3 , Figure 4 and Figure 5 A first air guide frame 117 is provided in the first evaporation chamber 111, and a first air duct 118 connected to the first air outlet 115 is arranged in the first air guide frame 117. A first assembly port 119 connected to the first air duct 118 is provided on the side of the first air guide frame 117 close to the first air inlet 114, and the first fan is installed on the first assembly port 119.

[0025] See also Figure 3 , Figure 4 and Figure 5 A first mounting frame 131 is further provided in the first evaporation chamber 111 and is located adjacent to the first air guide frame 117. The first mounting frame 131 is provided with a first mounting hollow portion 132 corresponding to the first air inlet 114. The first evaporator 13 is mounted on the first mounting hollow portion 132. In a specific embodiment, an angle is provided between the projection of the first evaporator 23 and the first air inlet 114 on the horizontal plane. By setting the above-mentioned angle, the first evaporator 23 is tilted relative to the first air inlet 114. Compared with the method in which the first evaporator 23 directly covers the first air inlet 114, this tilted setting method can increase the flow rate of the fluid entering the first evaporator 23 and improve the efficiency of heat exchange.

[0026] See also Figure 3 , Figure 4 and Figure 5 A second air guide frame 127 is provided in the second evaporation chamber 121, and a second air duct 128 connected to the second air outlet 125 is arranged in the second air guide frame 127.

The second mounting frame 141 is provided with a second mounting hollow portion 142 corresponding to the second air inlet 124. The second evaporator 23 is mounted on the second mounting hollow portion 142. In a specific embodiment, an angle is provided between the projection of the second evaporator 33 and the second air inlet 124 on the horizontal plane. By setting the above-mentioned angle, the second evaporator 33 is tilted relative to the second air inlet 124. Compared with a method in which the second evaporator 33 directly covers the second air inlet 124, this tilted setting method can increase the flow rate of the fluid entering the second evaporator 33 and improve the efficiency of heat exchange.

[0028] See also Figure 7 A preset gap 17 is provided between the first cavity 11 and the second cavity 12. Setting the gap can prevent the first cavity 11 and the second cavity 12 from directly contacting each other. Separating a certain gap can reduce the heat exchange efficiency between the two cavities and avoid mutual influence between the two cavities during thawing.

[0029] See also Figure 4 and Figure 7 A water outlet pipe 151 extending longitudinally is provided at the rear side of the cabinet 1, a first drain port 152 and a second drain port 153 are provided at the bottom of the first thawing chamber 112 and the second thawing chamber 122, respectively, the water outlet pipe 151 has a first drain pipe 154 connected to the first drain port 152, and a second drain pipe 155 connected to the second drain port 153, a third drain port 156 extending from the bottom of the cabinet 1 is formed at the bottom of the water outlet pipe 151, and the first drain pipe 154 is provided in the above-mentioned preset gap 17. By providing the water outlet pipe 151, water generated by thawing food can be collected, and by providing the first drain pipe 154 in the preset gap 17, the preset gap 17 can be effectively utilized, making the structure more compact.

[0030] See also Figure 2 and Figure 3 In order to improve the heat transfer efficiency in the second thawing chamber 122 , a plurality of third fans 16 are further provided on the second partition plate 123 .

[0031] Compared with the prior art, the utility model provides two thawing chambers, so that different ingredients can be thawed separately, especially raw and cooked frozen foods can be processed separately, solving the hygiene problem that bacteria carried by raw food can easily infect cooked food during the thawing process. The two thawing chambers will not affect or interfere with each other during the thawing process, so there will be no cross-flavor phenomenon, thus ensuring the hygiene and safety of the food, and ensuring that the taste of the food after thawing will not be affected.

[0032] See also Figure 2 The first thawing chamber 112 and the second thawing chamber 122 are respectively provided with base supports 181 on opposite sides thereof, and the first thawing chamber 112 and the second thawing chamber 122 are provided with barbs 182 on the rear side surfaces between the base supports 181 on both sides, and the base supports 181 and the barbs 182 are used to support the shelves.

[0033] As an improved solution, the first thawing chamber 112 and the second thawing chamber 122 are also provided with an ultrasonic atomizer (not shown in the figure), an ultrasonic generator (not shown in the figure), and an ultraviolet sterilizer (not shown in the figure). The ultrasonic atomizer continuously adds high-humidity water mist to the air involved in heat exchange. High-humidity air has a higher specific heat capacity than dry air, and can more efficiently take away the heat of the food package, thereby further improving the thawing efficiency. The ultrasonic generator uses the mechanical effect of ultrasound to effectively destroy ice crystals on the food and accelerate the thawing rate of frozen food. While ultrasound produces mechanical effects, it also produces thermal effects. When ultrasound drives the food to vibrate, it will increase the local temperature of the food, thereby heating it and further thawing it. The ultraviolet sterilizer can prevent the growth of bacteria.

[0034] As an improved solution, a water spray gun (not shown in the figure) is provided in the first thawing chamber 112 and the second thawing chamber 122 for spraying and cleaning the food to accelerate the thawing rate.
