[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0026] See Figures 1 to 6 This embodiment provides a defrosting device, including a cabinet 1 and a heat exchange system. The cabinet 1 is constructed with at least two accommodating chambers 11. The heat exchange system includes a compressor 2 and a condenser 3 disposed outside the cabinet 1, and at least two evaporator modules 4 disposed inside the cabinet 1 corresponding to each of the accommodating chambers 11. That is, each accommodating chamber 11 is provided with one evaporator module 4. Each evaporator module 4 includes a control component 46 and an evaporator 41. The at least two evaporator modules 4 are connected in parallel between the compressor 2 and the condenser 3. The condenser 3 is connected to the compressor 2. The conduction of each evaporator 41 and the compressor 2 is responsive to the control component 46 to selectively provide heat to the corresponding accommodating chamber 11. The connection between the evaporator 41 and the condenser 3 is a conventional capillary connection.

[0027] See Figures 1 to 3 , Figure 8 In this embodiment, there are three accommodating chambers 11, each of which is equipped with a door panel assembly 10 that can be opened or closed. The three accommodating chambers 11 are arranged longitudinally. The compressor 2 and the condenser 3 are located on the top of the cabinet 1, and the evaporator module 4 is located on the side of each accommodating chamber 11.

[0028] The heat exchange system further includes a reversing device 5, which is equipped with a first port connected to the refrigerant outlet of the compressor 2 and a reversing port connected to the compressor 2.

[0029] The reversing device 5 is equipped with a second port connected to the refrigerant inlet, a third port connected to the condenser 3, and a fourth port connected to the at least two evaporator modules 4. It also has switchable heating and cooling modes.

[0030] When in the cooling state, the first port is connected to the third port, the second port is connected to the fourth port, and the control component 46 selectively connects the compressor 2, the condenser 3 and the corresponding evaporator 41. The compressed refrigerant flows sequentially to the refrigerant outlet of the compressor 2, the reversing device 5, the condenser 3 and the corresponding evaporator 41, and then returns to the reversing device 5 and flows back to the refrigerant inlet of the compressor 2, thereby achieving the cooling of the corresponding accommodating chamber 11.

[0031] When in the heating state, the first port is connected to the fourth port, the second port is connected to the third port, and the control assembly 46 selectively connects the compressor 2, the corresponding evaporator 41 and the condenser 3, the compressed refrigerant flows in turn to the refrigerant outlet of the compressor 2, the reversing device 5, the corresponding evaporator 41, the condenser 3, and then returns to the reversing device 5 and flows back to the refrigerant inlet of the compressor 2, thereby realizing heating of the corresponding accommodation room 11.

[0032] The above arrangement can switch between the heating state and the cooling state by adding the reversing device 5 in the heat exchange system. When in the cooling state, the compressor 2 is connected to the condenser 3, and the evaporator module 4 can be selectively connected to the condenser 3; when in the heating state, the compressor 2 is directly connected to the evaporator module 4, thereby increasing the function of the thawing device, so that the food can be stored after thawing to prevent deterioration. For example, the reversing device 5 can be configured as a four-way reversing valve of the prior art.

[0033] The control assembly 46 includes a solenoid valve connected to the evaporator 41, which can accurately control the heating or cooling of the corresponding accommodation room 11. For example, when thawing or cooling of a certain accommodation room 11 is needed, the solenoid valve controls the corresponding evaporator 41 to communicate with the compressor 2 or the condenser 3. As a specific application scenario, the cabinet 1 is provided with three accommodation rooms 11. When thawing of the three accommodation rooms 11 is needed, each solenoid valve communicates the compressor 2 with the corresponding evaporator 41. When cooling of the three accommodation rooms 11 is needed, each solenoid valve communicates the condenser 3 with the corresponding evaporator 41. When only one or more accommodation rooms 11 need to work, the solenoid valve can control the connection of the compressor 2 or the condenser 3 with the corresponding evaporator 41, which is simple and convenient to operate. It should be noted that the solenoid valve uses the prior art, and its working principle is not the invention point of the patent, which will not be described here.

[0034] Referring to Figure 2 , Figures 4 to 7, the evaporator module 4 further comprises an air outlet plate 42, an air guide cover 43, and an air supply device 44, the air outlet plate 42 is configured to at least partially define a side wall of the accommodating chamber 11, and is configured with an air outlet 421 and a first air return opening 422, the air guide cover 43 is configured with an air guide cavity 431 which is open towards the air outlet plate 42, the evaporator 41 is arranged between the air guide cavity 431 and the air outlet plate 42 corresponding to the air outlet 421, and the air supply device 44 is configured to guide the airflow to be delivered from the air outlet 421 to the accommodating chamber 11 after passing through the evaporator 41. The above-mentioned air guide cover 43 optimizes the airflow path, prevents energy loss, and improves energy transmission efficiency. The first air return opening 422 improves the circulation effect of the airflow in the accommodating chamber 11. In combination with the air supply device 44, the air heated or frozen after passing through the evaporator 41 is delivered to the accommodating chamber 11, thereby ensuring uniform thawing of food materials during heating and uniform freezing during refrigeration.

[0035] Referring to Figure 2 , Figures 4 to 7 , as a more preferred solution, the air outlet plate 42 is configured with a second air return opening 423 on the side of the air outlet 421 opposite the first air return opening 422, both ends of the air guide cavity 431 are respectively configured with first air guide surfaces 432 which guide the airflow towards the middle part of the air guide cavity 431, and the middle part of the air guide cavity 431 is configured with a second air guide surface 433 and a third air guide surface 434 which respectively guide the airflow from both sides of the air guide cavity 431 to the evaporator 41. The above-mentioned air guide surfaces can effectively guide the airflow from both sides of the air guide cavity 431 to the evaporator 41, thereby improving the heating effect during heating and the freezing effect during refrigeration. Through the second air return opening 423, the first air return opening 422 forms a turbulent flow in the accommodating chamber 11, so that the food materials are heated or frozen more uniformly, the contact area between the airflow and the food materials is increased, and the thawing and freezing effects are improved.

[0036] Referring to Figure 4 and Figure 5 , in order to further improve the energy recycling effect, the evaporator module 4 further comprises an air guide channel 45 arranged around the first air return opening 422 and the second air return opening 423, and the air guide channel 45 extends towards the air guide cavity 431. The above-mentioned arrangement can cause the airflow to accurately flow back to the air guide cavity 431, so that the energy can be effectively recycled and utilized, and energy loss is avoided.

[0037] Referring to Figures 4 to 7 , in order to improve the heating speed, the air outlet 421 is arranged longitudinally in two, the evaporator 41 covers the two air outlets 421, and the air supply device 44 comprises fans 441 arranged on the air outlets 421 respectively. The above-mentioned arrangement further improves the flow speed of the airflow, and further improves the thawing and refrigeration effects.

[0038] Referring to Figure 5 The first air guide surface 432, the second air guide surface 433 and the third air guide surface 434 are configured as arc-shaped air guide surfaces extending towards the air outlet plate 42, wherein the second air guide surface 433 and the third air guide surface 434 are arranged in mirror symmetry, and the structure of the arc-shaped air guide surface can reduce air flow resistance and further optimize the flow path of the air flow.

[0039] As an improved scheme, a microwave emitter (not shown in the figure) is further arranged in each accommodation chamber 11, so that the microwave emitter can emit microwaves to the food, thereby accelerating the violent vibration of the liquid molecules on the food, and generating friction to accelerate the temperature rise.

[0040] Compared with the prior art, at least two accommodation chambers 11 are arranged in the cabinet body 1, and an independent evaporator module 4 is arranged in each accommodation chamber 11, so that different food can be placed in the corresponding accommodation chamber 11 for thawing according to the requirement, and the food in each accommodation chamber 11 does not affect each other during the thawing process, thereby improving the taste of the food. At the same time, each evaporator module 4 shares a compressor 2 and a condenser 3, which not only reduces the number and cost of the compression components, but also reduces the space occupation. In addition, the introduction of the reversing device 5 further optimizes the flow direction of the refrigerant, supports the switching between the heating and cooling states, increases the function of the thawing device, so that the thawed food can be stored in the frozen state to prevent deterioration. The structural design of the evaporator module 4, such as the arrangement of the air outlet plate 42, the air guide cover 43 and the air supply device 44, optimizes the air distribution, ensures that the energy can be uniformly transmitted to the food, improves the thawing and cooling effect, and the microwave emitter arranged in the accommodation chamber 11 can further assist heating and accelerate the thawing process.
