In order to solve the above problem, referring to fig. 4, in the embodiment of the present application, the first heat dissipation device 16 is further included, the first heat dissipation device 16 is disposed in the box 11 and is used for dissipating heat of the thawing compartment 500, and the thawing compartment 500, the tuner 153 and the electrode 154 in the thawing compartment 500 are dissipated heat by the specially disposed first heat dissipation device 16, so that on the basis of ensuring a good heat dissipation effect of the thawing compartment 500, the influence on the refrigeration storage of the refrigeration compartment 100 in the refrigerator 1 is reduced.

Since a large amount of heat is also generated in the thawing accommodating compartment 500B during the thawing process, the thawing accommodating compartment 500B is also required to be cooled by an appropriate cooling method.

For example, a dedicated communication duct 700 is provided in the box body 11, and the equipment housing compartment 500A and the defrosting housing compartment 500B are communicated through the communication duct 700, as shown in fig. 9.

Referring to fig. 3, the refrigerator 1 according to the embodiment of the present application further includes a first temperature detecting device 18, the first temperature detecting device 18 is installed in the equipment accommodating compartment 500A, and the first temperature detecting device 18 is configured to detect the temperature of the equipment accommodating compartment 500A.

Taking the rf thawing assembly 15 with the rf controller 157 as an example, the rf controller 157 is electrically connected to the first temperature detecting device 18 and the first cooling fan, and the rf controller 157 is further configured to control the first cooling fan to be turned on or off, or adjust the rotation speed of the first cooling fan, or control the first cooling fan to be turned on or off, and adjust the rotation speed of the first cooling fan according to the temperature value detected by the first temperature detecting device 18.

For example, when the rf thawing function of the refrigerator 1 is turned off or the heat generated by the rf thawing component 15 during the rf thawing process is low, the temperature value detected by the first temperature detecting device 18 is low (e.g. lower than the set lowest set temperature value), the rf controller 157 may control the first cooling fan to turn off or turn down the rotation speed of the first cooling fan to reduce the power consumption; when the heat generated by the rf thawing component 15 during the rf thawing process is high, the temperature value detected by the first temperature detecting device 18 is high (e.g. higher than the set heat dissipation temperature value), and the rf controller 157 can control the first heat dissipation fan to be turned on or increase the rotation speed of the first heat dissipation fan, so as to ensure the heat dissipation effect of the tuner 153.

The equipment accommodating chamber 500A and the thawing accommodating chamber 500B are both heat-dissipated by the first heat dissipation device 16. Fig. 6 shows that the equipment housing compartment 500A in the refrigerator 1 primarily dissipates heat using the first heat dissipation device 16, and the refrigeration cycle system 200 dissipates heat from the thawing housing compartment 500B.

For example, the thawing accommodation compartment 500B is located inside the refrigeration compartment 100; or, the thawing accommodation compartment 500B is located outside the refrigeration compartment 100 and is communicated with the refrigeration compartment 100, and the refrigeration cycle system 200 of the refrigerator 1 is used to perform auxiliary heat dissipation on the thawing accommodation compartment 500B, so that the heat dissipation effect on the thawing accommodation compartment 500B is ensured on the basis that the temperature influence of the refrigeration compartment 100 where the thawing accommodation compartment 500B is located or communicated is small.

Referring to fig. 3, the refrigerator 1 according to the embodiment of the present application further includes a first casing 501 and a second casing 502, wherein the thawing compartment 500 is formed in the first casing 501, the second casing 502 is sleeved outside the first casing 501, the second casing 502 is located in the refrigerating compartment 100, a cooling port is formed in the second casing 502, and the cooling port is respectively communicated with the refrigerating compartment 100 and the thawing accommodation compartment 500B in the first casing 501, so as to achieve communication between the thawing accommodation compartment 500B and the refrigerating compartment 100.

It should be noted that the first housing 501 and the second housing 502 are made of metal materials, and the first housing 501 made of metal materials not only has a good shielding effect on electromagnetic waves, but also has good heat conduction performance, and is suitable for the scheme of disposing the first housing 501 and the second housing 502 in the refrigeration compartment 100.

Based on the above, the air door 5021 is installed at the cooling port, and the air door 5021 is used for controlling the cooling port to be opened or closed. When the air door 5021 is opened, cold air in the refrigerating compartment 100 can enter the thawing accommodation compartment 500B, and the cold air can exchange heat with the thawing accommodation compartment 500B to realize heat dissipation of the thawing accommodation compartment 500B; when the temperature in the thawing accommodation compartment 500B is low, the air door 5021 is closed without heat dissipation of the thawing accommodation compartment 500B.

In order to better control the opening or closing of the damper 5021, the refrigerator 1 according to the embodiment of the present application further includes a second temperature detecting device 19, the second temperature detecting device 19 is installed in the thawing accommodation compartment 500B of the first casing 501, and the second temperature detecting device 19 is used for detecting the temperature of the thawing accommodation compartment 500B.

Taking the rf thawing assembly 15 with the rf controller 157 as an example, the rf controller 157 is electrically connected to both the second temperature detection device 19 and the air door 5021, and the rf controller 157 can control the opening or closing of the air door 5021 according to the temperature value detected by the second temperature detection device 19.

For example, when the temperature value detected by the second temperature detecting device 19 is higher than the preset heat dissipation temperature, the air door 5021 is controlled to be opened, and the cold energy of the refrigeration compartment 100 is used for performing auxiliary heat dissipation on the thawing accommodation compartment 500B; when the temperature value detected by the temperature detection device is lower than the preset heat dissipation temperature, the air door 5021 is controlled to be closed, cold air in the refrigerating chamber 100 does not need to enter the accommodating chamber 500B, and energy consumption is reduced.

It should be noted that, the first temperature detection device 18 and the second temperature detection device 19 may both adopt temperature sensors, and have small size and sensitive detection, and different types of temperature sensors may be selected according to specific working conditions.

If the rf power amplifier 152 and the rf power source 155 are both disposed in the compressor compartment 300, as shown in fig. 12, when leakage occurs in the refrigeration cycle 200 and electromagnetic wave leakage occurs in the rf power amplifier 152, there is a risk of explosion, so that the safety of the refrigerator 1 is reduced.

Because the installation shell 600 is arranged outside the box body 11 of the refrigerator 1 and the compressor bin 300 is positioned in the box body 11, namely the installation shell 600 and the compressor bin 300 are mutually independent, the oscillator 151, the radio frequency controller 157, the radio frequency power amplifier 152 and the radio frequency power supply 155 can be completely isolated from the refrigeration cycle system 200, thereby further improving the safety of the refrigerator 1; the oscillator 151, the radio frequency controller 157, the radio frequency power amplifier 152 and the radio frequency power supply 155 are not affected by the heat dissipation of the electronic components in the box body 11, so that the oscillator 151, the radio frequency controller 157, the radio frequency power amplifier 152 and the radio frequency power supply 155 are favorably cooled, and the radio frequency power amplifier is suitable for the scheme that the radio frequency power amplifier 152 and the radio frequency power supply 155 generate more heat.

Specifically, the corresponding mounting position may be determined according to the heat generation amount of each electronic component.

The mounting case 600 is located at any position outside the cabinet 11, and the mounting case 600 is disposed on the top of the cabinet 11 in consideration of the beauty and the transportation and storage, as shown in fig. 4.

It should be noted that, the heat conducting glue is disposed on the circuit board or the housing where each electronic component is located in the installation casing 600, and the heat conducting glue is connected to the wall surface of the installation casing 600, so that heat on the circuit board where each electronic component is located can be conducted to the wall surface of the installation casing 600 for heat dissipation.
