In some embodiments of the present application, the rf generating circuit composed of the oscillator 151, the rf power amplifier 152, the tuner 153 and the electrode 154 is electrically connected to the main power source 13, i.e., the main power source 13 supplies power to the rf generating circuit.

It should be noted that each electronic component in the above-mentioned rf thawing assembly 15 can be controlled by the main control board 12 of the above-mentioned refrigerator 1, and the oscillator 151 in the above-mentioned rf thawing assembly 15 is packaged and disposed on the main control board 12, as shown in fig. 6; or, referring to fig. 4 and 5, the above-mentioned radio frequency thawing assembly 15 further includes a radio frequency controller 157, the radio frequency controller 157 is electrically connected to the radio frequency power source 155, the oscillator 151, and the radio frequency power amplifier 152, respectively, and the oscillator 151 and the radio frequency power amplifier 152 are controlled by the radio frequency controller 157, and the control of the radio frequency thawing assembly 15 is independent from the refrigeration control of the refrigerator 1, and the interference is small; the oscillator 151 of the rf thawing assembly 15 may be packaged on a circuit board on which the rf controller 157 is disposed. Of course, the oscillator 151 may be provided on a separate circuit board.

For a particular installation location of the rf thawing assembly 15, the tuner 153 and the electrode 154 are both disposed within the thawing compartment 500, as shown in fig. 4, according to the working principle of the tuner 153 and the electrode 154.

If the rf power amplifier 152 and the rf power source 155 are both disposed in the compressor compartment 300, as shown in fig. 7, 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.

In order to solve the above problems, referring to fig. 4, 5 and 8, in the refrigerator 1 according to the embodiment of the present invention, an installation housing 400 is provided outside the refrigerator body 11, the radio frequency power amplifier 152 is disposed in the installation housing 400, since the installation housing 400 is disposed outside the refrigerator body 11 of the refrigerator 1 and the compressor compartment 300 is located in the refrigerator body 11, that is, the installation housing 400 and the compressor compartment 300 are independent from each other, the radio frequency power amplifier 152 can be completely isolated from the refrigeration cycle system 200, thereby solving the problems of explosion risk and reduced safety of the refrigerator 1 caused by leakage of electromagnetic waves of the radio frequency power amplifier 152 when the refrigeration cycle system 200 leaks; and the radio frequency power amplifier 152 is not affected by the heat dissipation of the electronic components in the box body 11, which is beneficial to the heat dissipation of the radio frequency power amplifier 152 and is suitable for the scheme that the radio frequency power amplifier 152 generates more heat.

The mounting case 400 is located at any position outside the cabinet 11, and the mounting case 400 is disposed on the top of the cabinet 11 in consideration of the beauty and the transportation and storage, as shown in fig. 4.

For the solution where the compressor compartment 300 protrudes toward the rear side of the casing 11 (i.e., the rear plate side of the casing), the mounting housing 400 may also be provided on the rear plate of the casing 1, and the rear plate of the mounting housing 400 may be designed to be flush with the compressor compartment 300 or not to exceed the compressor compartment 300.

Similarly, in some embodiments of the present application, the rf power source 155 is also disposed in the mounting case 400, so as to further improve the safety of the refrigerator 1 and facilitate heat dissipation of the rf power source 155; and because the radio frequency power supply 155 is placed close to the radio frequency power amplifier 152, the length of the connecting line between the radio frequency power supply 155 and the radio frequency power amplifier 152 can be shortened, and the cost is saved.

Similarly, in some embodiments of the present application, for the rf thawing assembly 15 having the rf controller 157, the rf controller 157 may be disposed in the mounting case 400, which may further improve the safety of the refrigerator 1 and facilitate heat dissipation.

In view of the above-described safety of the refrigerator 1 and the heat dissipation of the oscillator 151 and the main control board 12, the present application also provides both the oscillator 151 and the main control board 12 within the mounting case 400.

Since the main control board 12, the rf controller 157, the oscillator 11, the rf power amplifier 152, and the rf power source 155 are collectively disposed in the mounting case 400, the lengths of the connection line between the rf controller 157 and the rf power amplifier 152, the connection line between the rf controller 157 and the rf power source 155, and the like are short; and a heat dissipation device can be adopted to simultaneously dissipate heat of the main control board 12, the radio frequency controller 157, the oscillator 11, the radio frequency power amplifier 152 and the radio frequency power supply 155, so that the cost is saved.

The connection lines between the main control board 12 or the rf controller 157 and the rf power source 155, the oscillator 151, the rf power amplifier 152, and the tuner 153 are communication lines.

It should be noted that, for the rf thawing assembly 15 having the rf controller 157, referring to fig. 4, fig. 5 and fig. 9, the oscillator 151, the rf power amplifier 152 and the rf controller 157 in the rf thawing assembly 15 may all be disposed on the same circuit board, and the integration level is high, and of course, the oscillator 151, the rf power amplifier 152 and the rf controller 157 in the rf thawing assembly 15 may also be disposed on different circuit boards respectively.

In addition, referring to fig. 4, the refrigerator 1 according to the embodiment of the present application further includes a switch device 156, and the switch device 156 is used for controlling on/off of the rf power source 155, that is, controlling the rf power source 155 to supply power or stop supplying power. When the radio frequency power supply 155 stops supplying power, the whole radio frequency thawing assembly 15 stops running, so that the interference on normal refrigeration of the refrigerator 1 is reduced, the radio frequency thawing assembly 15 can be prevented from being touched by mistake, and the safety is high. The switch device 156 may be a control switch such as a relay or a breaker, or the switch device 156 may be a switch circuit such as a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) Transistor switch circuit.

In some embodiments, referring to fig. 10, the main power supply 13 and the rf power supply 155 are disposed on the same circuit board, and different output voltages are output by using the same transformer and different numbers of turns, so that the cost is low.

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 400, and the heat conducting glue is connected to the wall surface of the installation casing 400, so that heat on the circuit board where each electronic component is located can be conducted to the wall surface of the installation casing 400 for heat dissipation. In order to increase the heat dissipation speed of the mounting case 400, the case of the mounting case 400 is made of a metal material, and has a high thermal conductivity and a high thermal conductivity.

Of course, the second heat dissipation fan may be directly disposed in the thawing compartment 500.

It should be noted that, air doors may be installed at the air inlet 111 and the air outlet 112, and the air doors control the opening or closing of the corresponding holes, and when heat dissipation is not required, the air doors close the holes to prevent dust from entering the box 11.

When the air door 5021 is opened, cold air in the refrigerating compartment 100 can enter the second shell 502 and exchange heat with the first shell 501, so that the first shell 501 is cooled; when the temperature of the first housing 501 is low, the first housing 501 does not need to be cooled, and the air door 5021 is closed.

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

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 first shell 501; when the temperature value detected by the second temperature detecting device 19 is lower than the preset heat dissipation temperature, the air door 5021 is controlled to be closed, and cold air in the refrigerating compartment 100 does not need to enter the second shell 502, so that 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.

In some embodiments, the object to be thawed 1000 is placed in the thawing compartment 500, and the object to be thawed 1000 is located in the same compartment as the tuner 153 and the electrode 154.

Accordingly, the first temperature detection device 18 described above is provided in the equipment housing compartment 500A, and the second temperature detection device 19 is provided in the defrosting housing compartment 500B.

When a user inputs a thawing command through the control panel 14, the main control panel 12 or the radio frequency controller 157 receives the thawing command, controls the air doors at the air inlet 111 and the air outlet 112 to be opened, starts the second heat dissipation device 17 at the same time, and then switches on the radio frequency power supply 155, the radio frequency power supply 155 supplies power to a radio frequency generation circuit composed of the oscillator 151, the radio frequency power amplifier 152, the tuner 153, and the electrode 154, the oscillator 151 generates a fundamental frequency signal, the radio frequency power amplifier 152 amplifies the power of the fundamental frequency signal generated by the oscillator 151 to a set power, the tuner 153 tunes the amplified radio frequency signal output by the radio frequency power amplifier 152, and the electrode 154 radiates the radio frequency signal of the tuner 153 to the object 1000 to be thawed, thereby thawing the object 1000 to be thawed.

In the thawing process, when the temperature value of the tuner 153 detected by the first temperature detecting device 18 is higher than the set heat dissipation temperature value, the second heat dissipation fan is controlled to be turned on or kept turned on, and the rotating speed of the second heat dissipation fan is adjusted according to the temperature range of the detected temperature value; when the temperature value of the tuner 153 detected by the first temperature detecting device 18 is lower than the lowest set temperature value, the second cooling fan is controlled to be turned off. Meanwhile, when the temperature value of the thawing compartment 500 detected by the second temperature detection device 19 is higher than the preset heat dissipation temperature, the air door 5021 on the second shell 502 is controlled to be opened; when the temperature value of the thawing compartment 500 detected by the second temperature detecting device 19 is lower than the preset heat dissipation temperature, the air door 5021 on the second casing 502 is controlled to be closed.
