The support bracket 14 includes a mounting portion 143 and a fixing portion 141 connected to each other, the tuning plate 15 is mounted on the fixing portion 141, and the pole plate 16 is mounted on the mounting portion 143.

When the tuning plate 15 and the pole plate 16 are both mounted on the support bracket 14, since the tuning plate 15 and the pole plate 16 have different functions in the radio frequency thawing device 10 and are disposed at different positions, the tuning plate 15 and the pole plate 16 need to be mounted and fixed through different positions on the support bracket 14, so that the support bracket 14 is provided with the mounting portion 143 and the fixing portion 141 connected to each other, the tuning plate 15 is mounted on the fixing portion 141 of the support bracket 14, and the pole plate 16 is mounted on the mounting portion 143 of the support bracket 14, thereby ensuring that the tuning plate 15 and the pole plate 16 are disposed at positions required in the radio frequency thawing device 10 to achieve respective functional effects.

The mounting portion 143 and the fixing portion 141 of the support bracket 14 are integrally formed, so that the number of assembling steps in the machining process can be reduced, the production cost can be reduced, and the production efficiency can be improved.

In addition, the support bracket 14 is a structural member for fixing and supporting the tuning plate 15 and the pole plate 16, and it is necessary that the support bracket 14 has sufficient support stability, and the support stability of the support bracket 14 using the assembled structure is lower than that of the support bracket 14 using the integrated structure.

It should be noted that, the mounting portion 143 and the fixing portion 141 of the support bracket 14 may be integrally formed, or may be formed by separately processing and assembling in other embodiments, which is not limited in this embodiment.

Because the rf thawing apparatus 10 generally needs to use higher power to achieve the functional effect, the tuning inductor 17 has higher current and voltage, which can form a greater safety risk for the tuning plate 15 and nearby components. The tuning inductor 17 is mounted on the second mounting area 153, and the first mounting area 151 is mainly used for mounting other electronic components, so that the influence of the tuning inductor 17 on other electronic components in the working process can be reduced.

Since the tuning inductor 17 is mounted to the second mounting area 153 of the tuning plate 15, specifically, the tuning inductor 17 is mounted in the mounting groove 153a of the second mounting area 153. Compared with other electronic components, the tuning inductor 17 has a larger volume, is inconvenient to be fixedly connected with the fixing portion 141 of the support bracket 14, and the fixing portion 141 is fixedly connected with the first mounting region 151, so that the connection stability of the tuning plate 15 and the support bracket 14 can be ensured under the condition that the operation of the tuning inductor 17 is not affected.

In some embodiments, the cartridge assembly 11 includes a support 112, a shielding member 111, and a partition 114, the shielding member 111 is sleeved on the support 112, and the partition 114 partitions the interior of the support 112 into the thawing chamber 11b and the tuning chamber 11a.

The shielding piece 111 is a structural component in the barrel assembly 11, and is mainly used for shielding radio frequency energy emitted by the radio frequency signal emitter, the supporting piece 112 is used as a supporting part of the barrel assembly 11, and the shielding piece 111 is sleeved on the supporting piece 112 to be used for supporting the shielding piece 111 so as to prevent the shielding piece 111 from deforming, namely, the shielding piece 111 maintains the appearance under the supporting action of the supporting piece 112, so that the deformation of the shielding piece 111 is avoided, the appearance stability of the shielding piece 111 is ensured, the shielding effect of the shielding piece 111 is improved, and the thawing effect is correspondingly improved.

The partition 114 divides the inside of the support 112 into a defrosting cavity 11b and a tuning cavity 11a to form a tuning cavity 11a and a defrosting cavity 11b in the barrel assembly 11, which are independent of each other, wherein the tuning cavity 11a is used for setting the support bracket 14, the tuning plate 15 and the polar plate 16, and the defrosting cavity 11b is used for placing food, so that the polar plate 16 and the tuning plate 15 are isolated from the food, and the polar plate 16 and the tuning plate 15 are prevented from being damaged by water vapor generated in the defrosting process of the food.

In some embodiments, the support 112 is integrally formed with the partition 114.

Since the rf thawing apparatus 10 has many structural members, the rf thawing apparatus 10 has many assembly steps during the processing, which affects the production efficiency.

Based on the same inventive concept, the embodiment of the present application also provides a refrigerator, and in conjunction with fig. 13 to 15, the refrigerator 100 provided in the embodiment of the present application includes a main body 20 and a radio frequency thawing device 10. Wherein the main body 20 is a basic component of the refrigerator 100 of the present application, the main body 20 may provide a mounting base for other at least partial components of the refrigerator 100, and may also serve the purpose of protecting the other at least partial components of the refrigerator 100. The main body 20 is provided with a mounting cavity 21, and the radio frequency thawing device 10 is arranged in the mounting cavity 21.

The radio frequency thawing device 10 and the mounting cavity 21 are provided with a gap, the tuning cavity 11a is provided with an air inlet 46 and an air outlet 47 which are communicated with the gap, so that air circulation is formed among the gap, the air inlet 46, the air outlet 47 and the thawing cavity 11b, and heat in the thawing cavity 11b can be continuously taken away by air in the flowing process, so that the temperature in the tuning cavity 11a is reduced, damage to a high Wen Duidiao tuning module is avoided to a certain extent, and the performance of the tuning module is ensured.

In some embodiments, the rf thawing device 10 has more than one sidewall 41, and the air inlet 46 and the air outlet 47 are both disposed on the sidewall 41 of the rf thawing device 10 to communicate with the gap between the rf thawing device 10 and the mounting cavity 21. Specifically, the air inlet 46 and the air outlet 47 may be disposed on the same side wall 41 of the rf thawing device 10, or may be disposed on different side walls 41, which is not limited in this embodiment.

Since the air inlet 46 and the air outlet 47 are commonly disposed on the same side wall 41 of the rf thawing device 10, that is, the air inlet 46 and the air outlet 47 are disposed in a coplanar manner, the heat discharged from the tuning cavity 11a is not completely dissipated, and then the heat is circulated into the tuning cavity 11a, resulting in lower heat dissipation efficiency.

Specifically, the rf thawing apparatus 10 has a first sidewall 41a and a second sidewall 41b, the air inlet 46 is disposed on the first sidewall 41a, and the air outlet 47 is disposed on the second sidewall 41 b. Of course, the first side wall 41a and the second side wall 41b have a gap with the installation cavity 21, and the space between the first side wall 41a and the installation cavity 21 and the space between the second side wall 41b and the installation cavity 21 are communicated, so that air circulation is formed between the air inlet 46, the air outlet 47, the gaps between the first side wall 41a and the second side wall 41b and the installation cavity 21, and heat dissipation is performed on the tuning cavity 11a.

The first sidewall 41a and the second sidewall 41b may be disposed opposite to each other or may be disposed in a connecting manner, which is not limited in this embodiment. When the first sidewall 41a and the second sidewall 41b are connected, the first sidewall 41a and the second sidewall 41b are connected at an included angle, and specifically, the first sidewall 41a and the second sidewall 41b may be connected vertically.

In some embodiments, the number of the second side walls 41b may be two, and the two second side walls 41b are provided with the air outlets 47, so that two air circulation loops are formed, and the two air circulation loops radiate the heat of the tuning cavity 11a at the same time, thereby improving the heat radiation efficiency and enhancing the heat radiation effect. Of course, on the premise of ensuring the protection effect of the tuning cavity 11a on the tuning module, more air outlets 47 can be provided, so that more air circulation loops are formed, and the heat dissipation efficiency is improved.

The two second side walls 41b may be disposed opposite to each other, that is, the two second side walls 41b are disposed opposite to each other on both sides of the first side wall 41a, so as to achieve heat dissipation on both opposite sides of the tuning cavity 11a. Specifically, the first side wall 41a may be a rear wall of the rf thawing apparatus 10, and the two second side walls 41b may be an upper wall and a lower wall of the rf thawing apparatus 10, respectively.

Namely, under the action of the heat dissipation fan 43, the hot air in the tuning cavity 11a is discharged from the air outlet 47, meanwhile, the cold air source blown by the heat dissipation fan 43 is continuously blown into the tuning cavity 11a, the temperature of the cold air is relatively low, more heat in the tuning cavity 11a can be taken away, the heat exchange efficiency is improved, and the discharge rate of the hot air in the tuning cavity 11a is greatly improved due to the fact that the flow rate of the cold air is high.

When the rf thawing device 10 works, the tuning module continuously generates heat, and the generated heat is discharged from the air outlet 47 and is dispersed into the gap between the rf thawing device 10 and the mounting cavity 21, but after the rf thawing device 10 works for a long time, the gap between the rf thawing device 10 and the mounting cavity 21 is filled with high-temperature gas, so that the tuning cavity 11a cannot be cooled, and the gap between the rf thawing device 10 and the mounting cavity 21 needs to be communicated with an external space, so that the heat discharged from the air outlet 47 can be dispersed to the outside, and the formation of high temperature around the rf thawing device 10 is avoided.

Specifically, since the air outlet 47 is provided on the second side wall 41b, the gap between the second side wall 41b and the installation cavity 21 communicates with the external space, so that the heat discharged through the air outlet 47 can be dissipated to the external space through the gap between the second side wall 41b and the installation cavity 21.

Specifically, the bracket 45 includes a resisting portion 45a and a supporting portion 45b, the rf thawing apparatus 10 is mounted on the resisting portion 45a, and the resisting portion 45a is supportingly disposed on the supporting portion 45b so that a lower wall of the rf thawing apparatus 10 maintains a gap with the mounting cavity 21.
