The present application is described below with reference to specific embodiments in conjunction with the accompanying drawings:

with reference to fig. 2-8, the embodiment of the application provides a radio frequency thawing device 100, and the radio frequency thawing device 100 provided in the embodiment of the application can strengthen the connection strength between the shielding door 123 and the panel 125, reduce the risk of mutual movement between the shielding door 123 and the panel 125, enable the shielding door 123 to be blocked at the opening of the box assembly 110, and form a closed first shielding cavity 112 with the box assembly 110, so as to reduce the occurrence of magnetic leakage when the polar plate 130 radiates radio frequency energy.

The radio frequency thawing device 100 provided in the embodiments of the present application includes a box assembly 110, a drawer assembly 120, and a polar plate 130. The housing assembly 110 has a first shielded cavity 112; the drawer assembly 120 includes a drawer body 200, a shielding door 123 and a panel 125, one side of the shielding door 123 is connected with the drawer body 200, the other side of the shielding door 123 is connected with the panel 125, and the drawer body 200 is used for accommodating food to be thawed and is disposed in the first shielding cavity 112; the pole plate 130 is disposed in the first shielding cavity 112 for radiating radio frequency energy to the drawer assembly 120 to defrost food to be defrosted in the drawer body 200.

Wherein, in shielding door 123 and panel 125 two, one of them is provided with the portion of holding 124, and the other one is provided with guide part 126 and backstop portion 127, and under the condition that the portion of holding 124 is in place for guide part 126 slip, backstop portion 127 stops that the portion of holding 124 breaks away from with guide part 126 to can avoid shielding door 123 to break away from in panel 125, strengthen the joint strength of shielding door 123 and panel 125, guaranteed the shielding effect of shielding door 123.

The box assembly 110 is a basic component of the rf thawing device 100 of the present application, and the box assembly 110 can provide a mounting base for other at least partial components of the rf thawing device 100 and can also serve the purpose of protecting the other at least partial components of the rf thawing device 100. Both the food to be thawed and the polar plate 130 are disposed in the first shielding cavity 112, and when the polar plate 130 radiates energy to the food to be thawed, the first shielding cavity 112 can shield the radiation energy to avoid energy leakage.

Food to be thawed is accommodated in the drawer assembly 120, the drawer assembly 120 is slidably disposed in the box assembly 110, specifically, an opening is formed on one side of the box assembly 110, and the drawer assembly 120 is movably connected with the box assembly 110, so that the food can be taken in or put out through the drawer assembly 120 by sliding into or out of the first shielding cavity 112 from the opening, and of course, the drawer assembly 120 can be slidably connected with the box assembly 110 through the sliding rail assembly. When the drawer assembly 120 is slid fully into the first shielding cavity 112, the drawer assembly 120 and the first shielding cavity 112 together form a closed shielding chamber to shield the plate 130 from the radiant energy.

The drawer assembly 120 includes a drawer main body 200, a shielding door 123 and a panel 125, where, under the condition that the drawer assembly 120 completely enters the first shielding cavity 112, the shielding door 123 can close the opening of the box assembly 110, so that the shielding plate and the first shielding cavity 112 form a closed shielding cavity, and the shielding plate can be obliquely arranged relative to the drawer main body 200 to increase the abutting area of the shielding plate and the opening of the box assembly 110, and of course, the projection of the opening of the box assembly 110 along the horizontal direction needs to be located in the outer contour of the shielding door 123, so as to ensure that the shielding door 123 completely covers the opening of the box assembly 110 and block the radio frequency signal from covering leakage. Since the shielding door 123 is required to shield rf energy, the shielding door 123 may be a metal member, and the panel 125 and the drawer body 200 may be plastic members to reduce weight.

One of the shielding door 123 and the panel 125 is provided with a holding portion 124, and the other is provided with a guide portion 126 and a stopper portion 127, that is, the shielding door 123 is provided with the holding portion 124, the panel 125 is provided with the guide portion 126 and the stopper portion 127, or the panel 125 is provided with the holding portion 124, and the shielding door 123 is provided with the guide portion 126 and the stopper portion 127, which is not limited thereto.

The shielding door 123 is used to form the first shielding cavity 112 by abutting against the shielding member 114, and is made of a metal material, and may be thinner in size, while the panel 125 is a mounting structure for mounting the shielding door 123, and may be made of a plastic material, and is thicker in size, so in some embodiments, the shielding door 123 may be provided with a clamping portion 124, and the panel 125 may be provided with a guiding portion 126 and a stopping portion 127. For convenience of description, the guide portion 126 and the stop portion 127 are disposed on the panel 125, and the retaining portion 124 is disposed on the shielding door 123, and the like, if the guide portion 126 and the stop portion 127 are disposed on the shielding door 123, the retaining portion 124 is disposed on the panel 125.

The clamping part 124 corresponds to the guiding part 126, the clamping part 124 slides relative to the guiding part 126 in the process of mounting the shielding door 123 on the panel 125, and after the clamping part 124 slides relative to the guiding part 126 in place, the stopping part 127 limits the clamping part 124 so as to prevent the clamping part 124 from separating from the guiding part 126, thereby preventing the shielding door 123 from separating from the panel 125, enhancing the connection effect of the shielding door 123 and the panel 125, reducing the risk of mutual movement of the shielding door 123 and the panel 125, enabling the shielding door 123 to be blocked at the opening of the box assembly 110 and forming a closed first shielding cavity 112 with the box assembly 110, and reducing the magnetic leakage when the polar plate 130 radiates radio frequency energy.

In addition, the clamping portions 124, the guiding portions 126 and the stopping portions 127 may be multiple, and the clamping portions 124, the guiding portions 126 and the stopping portions 127 may be uniformly distributed on the periphery of the shielding door 123 and the panel 125, so as to enhance the connection effect, of course, each clamping portion 124 corresponds to one guiding portion 126 and each stopping portion 127, and under the cooperation of the clamping portions 124, the guiding portions 126 and the stopping portions 127, the connection between the shielding door 123 and the panel 125 is realized.

In some embodiments, the guide portion 126 has a mounting surface 126a and an obliquely disposed guide surface 126b, and the catch 124 is slidable relative to the guide surface 126b and is disposed on the mounting surface 126a after sliding into place. That is, the guide surface 126b and the mounting surface 126a are provided in this order along the moving direction of the holding portion 124, and of course, the guide surface 126b and the mounting surface 126a are provided continuously, and the mounting surface 126a may be a flat surface.

In the sliding process of the clamping portion 124 relative to the guiding surface 126b, since the clamping portion 124 moves in the height direction of the panel 125 and the guiding surface 126b is obliquely arranged, the clamping portion 124 generates certain deformation in the moving process from the guiding surface 126b to the mounting surface 126a, when the clamping portion 124 moves to the mounting surface 126a, the shielding door 123 and the panel 125 are assembled, and at the moment, the whole clamping portion 124 after deformation is blocked by the blocking portion 127, so that the shielding door 123 cannot be separated from the panel 125, thereby improving the fixing effect between the panel 125 and the shielding door 123, reducing the risk of mutual movement of the shielding door 123 and the panel 125, enabling the shielding door 123 to be blocked at the opening of the box assembly 110, and forming a closed first shielding cavity 112 with the box assembly 110, so as to reduce the occurrence of magnetic leakage when the polar plate 130 radiates radio frequency energy.

In some embodiments, the retaining portion 124 includes a connecting section 124a and a retaining section 124b that are connected to each other, where an end of the connecting section 124a away from the retaining section 124b is connected to the shielding door 123, and the connecting section 124a deforms during sliding of the retaining section 124b relative to the guiding surface 126b, so that the retaining section 124b is disposed on the mounting surface 126a.

In the process that the clamping section 124b slides relative to the panel 125, as the clamping section 124b moves in the height direction of the panel 125, the connecting section 124a generates certain deformation, after the clamping section 124b moves to the mounting surface 126a, the connecting section 124a deforms, and the whole clamping section 124 after deformation is blocked by the blocking part 127, so that the shielding door 123 cannot be separated from the panel 125, the fixing effect between the panel 125 and the shielding door 123 is improved, the risk of mutual movement of the shielding door 123 and the panel 125 is reduced, the shielding door 123 can be blocked at the opening of the box assembly 110, and a closed first shielding cavity 112 is formed with the box assembly 110, so that the magnetic leakage condition when the polar plate 130 radiates radio frequency energy is reduced.

In this case, the connecting section 124a is made of a deformable material because the connecting section 124a is deformed. Specifically, the connection section 124a may be made of a metal material.

In some embodiments, the width of the retaining segment 124b is greater than the width of the connecting segment 124 a. In the process of sliding the clamping portion 124 relative to the guiding surface 126b, the connecting section 124a with smaller width can be more easily deformed, so that the clamping section 124b can be more smoothly disposed on the mounting surface 126a.

The clamping section 124b with a larger width is more easily limited by the stop portion 127, so that the limiting effect of the stop portion 127 can be improved, the risk of mutual movement of the shielding door 123 and the panel 125 is reduced, and the magnetic leakage caused by the radiation of radio frequency energy by the polar plate 130 is reduced.

In the condition that the shielding door 123 is provided with the catching portion 124, the catching portion 127 and the guide portion 126 are provided close to the shielding door 123, that is, the catching portion 127 and the guide portion 126 are provided in order along the moving direction of the catching portion 124. Thus, when the retaining portion 124 slides in place on the guiding portion 126, the stopping portion 127 can stop the deformed retaining portion 124, so as to prevent the retaining portion 124 from moving reversely, and prevent the retaining portion 124 from being separated from the guiding portion 126.

In some embodiments, the stop portion 127 includes two stop segments 127a, the two stop segments 127a being spaced apart, a distance between the two stop segments 127a being less than a width of the retaining segment 124 b.

Because the width of the holding section 124b is greater than the distance between the two stop sections 127a, the holding section 124b disposed on the mounting surface 126a cannot enter between the two stop sections 127a, that is, under the combined action of the two stop sections 127a, the holding section 124b can be blocked, so that the holding section 124b cannot be separated from the guide portion 126, thereby improving the fixing effect between the panel 125 and the shielding door 123, reducing the risk of mutual movement of the shielding door 123 and the panel 125, and enabling the shielding door 123 to be blocked at the opening of the box assembly 110 to form a closed first shielding cavity 112 with the box assembly 110, so as to reduce the occurrence of magnetic leakage when the polar plate 130 radiates radio frequency energy.

In some embodiments, in the moving direction of the holding portion 124 relative to the guiding portion 126, the guiding portion 126 needs to be offset from the stopping portion 127, so as to ensure that the holding portion 124 can reach the guiding portion 126 through the stopping portion 127 during the moving process.

As described above, the stop portion 127 and the guide portion 126 are sequentially disposed along the movement direction of the holding portion 124, so that when the holding portion 124 slides on the guide portion 126 in place, the stop portion 127 can stop the holding portion 124, preventing the holding portion 124 from moving reversely, so as to stop the holding portion 124 from separating from the guide portion 126. Therefore, the retaining portion 124 passes through the stop portion 127 before reaching the guide portion 126, and the guide portion 126 and the stop portion 127 are arranged in a staggered manner, so that the retaining portion 124 is not interfered by the stop portion 127 and reaches the guide portion 126 smoothly.

Specifically, the guide portion 126 and the two stop portions 127 are both disposed in a staggered manner. The guiding portion 126 may be disposed between the two stopping portions 127, so that the width of the holding section 124b only needs to be slightly larger than the distance between the two stopping portions 127, and the two stopping portions 127 can stop the holding section 124 b.

In some embodiments, the panel 125 is provided with a mounting groove 125a under the condition that the stopper 127 and the guide 126 are disposed on the panel 125, the guide 126 is disposed in the mounting groove 125a, and the stopper 127 is disposed at an opening of the mounting groove 125 a.

Since the guide portion 126 and the stop portion 127 are disposed in the mounting groove 125a, the guide portion 126 and the stop portion 127 can be prevented from occupying additional space on the panel 125, and the size of the panel 125 can be increased, so that the whole rf thawing apparatus 100 can be prevented from occupying more space in the electrical equipment 10.

The stop portion 127 is disposed at the opening of the mounting groove 125a, that is, the stop portion 127 is disposed at the edge of the mounting groove 125a, and of course, the stop portion 127 is disposed at the edge of the panel 125 near the shielding door 123, so as to reduce the size of the mounting groove 125a and avoid the larger size of the mounting groove 125a from affecting the overall strength of the panel 125.

In some embodiments, the stop portion 127 and the side wall of the mounting groove 125a form a connection channel 128, and the clamping portion 124 is disposed in the connection channel 128.

As described above, the retaining portion 124 passes through the stop portion 127 before reaching the guiding portion 126, and after the stop portion 127 and the side wall of the mounting groove 125a form the connecting channel 128, the retaining portion 124 can reach the guiding portion 126 through the connecting channel 128. It is apparent that the guide portion 126 is disposed on the bottom sidewall of the mounting groove 125a, and the stop portion 127 and the bottom sidewall of the mounting groove 125a form a connection channel 128, so that the clamping portion 124 can directly reach the guide portion 126 from the connection channel 128.

That is, during the installation process of the shielding plate and the panel 125, the clamping portion 124 is firstly clamped into the connecting channel 128 formed by the stop portion 127 and the side wall of the installation groove 125a, and then continues to move so as to reach the guiding portion 126, as the clamping portion 124b moves in the height direction of the panel 125, the connecting portion 124a can generate a certain deformation, after the clamping portion 124b moves onto the installation surface 126a, the connecting portion 124a deforms, and the whole deformed clamping portion 124 is blocked by the stop portion 127, so that the shielding door 123 cannot be separated from the panel 125, thereby improving the fixing effect between the panel 125 and the shielding door 123, reducing the risk of the mutual movement of the shielding door 123 and the panel 125, enabling the shielding door 123 to be blocked at the opening of the box assembly 110, and forming a closed first shielding cavity 112 with the box assembly 110, so as to reduce the occurrence of magnetic leakage when the polar plate 130 radiates radio frequency energy.

Of course, in other embodiments, the guide portion 126 and the stopper portion 127 may be provided for the shield door 123, and the holding portion 124 may be provided for the panel 125, which is not limited in this example.

In some embodiments, the height of the portion of the stop 127 is lower than the height of the mounting surface 126a.

When the retaining portion 124 is disposed on the mounting surface 126a, a portion of the blocking portion 127 lower than the mounting surface 126a can block the retaining portion 124, so as to block the retaining portion 124 from moving out of the connecting channel 128 and separating from the guiding portion 126. That is, the blocking portion 127 can block the blocking portion 124 in two aspects, that is, the two blocking sections 127a can prevent the blocking section 124b from moving in opposite directions into between the two blocking sections 127a, and the portion of the blocking portion 127 lower than the mounting surface 126a can prevent the blocking section 124b from moving in opposite directions into the connecting channel 128, so that the fixing effect between the panel 125 and the shielding door 123 is further improved, and the magnetic leakage when the polar plate 130 radiates radio frequency energy is reduced.

Specifically, the height of the portion of the stopper 127 on the side close to the mounting surface 126a is lower than the height of the mounting surface 126a. When the retaining portion 124 tends to be separated from the guiding portion 126, the retaining portion 127 immediately blocks the retaining portion 124 to prevent the retaining portion 124 from sliding continuously, because the height of the portion of the retaining portion 127 near the mounting surface 126a is lower than the height of the mounting surface 126a.

In some embodiments, the rf thawing apparatus 100 further comprises a power amplifier module 154, the housing assembly 110 further comprises a second shielding cavity 113, and the power amplifier module 154 is disposed in the second shielding cavity 113.

In addition, the first shielding cavity 112 and the second shielding cavity 113 are mutually independent in the box assembly 110, so that even if the drawer assembly 120, the polar plate 130 and the power amplification module 154 are all arranged in the box assembly 110, the influence of the power amplification module on the radio frequency energy of the polar plate 130 can be avoided to a certain extent, and the mutual interference of the power amplification module 154 and the polar plate 130 can not be caused.

The first shielding cavity 112 further comprises a tuning cavity 112a and a thawing cavity 113a, food to be thawed is arranged in the thawing cavity 113a, and the polar plate 130 is arranged in the tuning cavity 112a, so that the polar plate 130 is isolated from the food, and the damage to the tuning plate and the polar plate 130 caused by water vapor generated in the thawing process of the food is avoided.

Namely, the first shielding cavity 112 and the second shielding cavity 113 are separated by the shielding partition 114b, so that the influence of the power amplifier module on the radio frequency energy of the polar plate 130 can be avoided to a certain extent.

The first shielded cavity 112 also has an opening for movement of the drawer assembly 120 relative to the housing assembly 110, and the shielding partition 114b is disposed opposite the opening, i.e., the first shielded cavity 112 and the second shielded cavity 113 are disposed side-by-side. The drawer assembly 120 is movably connected with the box assembly 110, and can slide into or slide out of the thawing cavity 113a from the opening to achieve taking and placing of food, and when the drawer assembly 120 slides into the thawing cavity 113a completely, the drawer assembly 120 and the first shielding cavity 112 form a closed shielding cavity together to shield radiant energy, so that energy leakage is avoided.

Specifically, the first shielding chamber 112 and the second shielding chamber 113 are disposed in a front-to-rear direction, so that when the radio frequency thawing device 100 is disposed in the electrical equipment 10, a space occupying the width direction in the electrical equipment 10 can be reduced, so that additional space in the width direction in the electrical equipment 10 can accommodate other members, and an accommodating space of the electrical equipment 10 can be increased.

Referring to fig. 2 and 8, in some embodiments, the shielding shell includes an upper cover 114a and a shielding main body 114c, the upper cover 114a is fixedly connected with the shielding main body 114c, the shielding main body 114c is in an integral structure to ensure structural strength of the shielding main body 114c, and a shielding partition 114b is disposed at one end of the upper cover 114a and the shielding main body 114c and is fixedly connected with at least one of the upper cover 114a and the shielding main body 114c, so as to enclose a first shielding cavity 112 with the shielding main body 114c and the upper cover 114 a.

The shielding partition 114b may be connected to the upper cover 114a, or may be connected to the shielding main body 114c, or may be connected to both the upper cover 114a and the shielding main body 114c, so as to further secure structural strength, and the shielding partition 114b may be connected to the shielding main body 114 c/the upper cover 114a by welding, screwing, or the like, which is not limited.

In some embodiments, the shielding main body 114c includes a first side plate 1141, a bottom plate 1142, and a second side plate 1143, the first side plate 1141 and the second side plate 1143 are respectively connected to two sides of the bottom plate 1142, the upper cover 114a is connected to a side of the first side plate 1141 and the second side plate 1143 away from the bottom plate 1142, the shielding partition 114b is connected to one ends of the upper cover 114a, the first side plate 1141, the bottom plate 1142, and the second side plate 1143, so as to enclose the first shielding cavity 112, and the other end of the shielding main body 114c may be configured as an opening matched with the drawer assembly 120.

The first side plate 1141, the bottom plate 1142 and the second side plate 1143 may be integrally formed, that is, the shielding main body 114c is a unitary structure, so that when the shielding main body 114c is assembled with the upper cover 114a and the shielding partition 114b, the first side plate 1141, the bottom plate 1142 and the second side plate 1143 do not need to be assembled, so that the overall installation of the box assembly 110 is more convenient.

In some embodiments, the rf thawing apparatus 100 further comprises a tuning inductor 140, wherein the tuning inductor 140 is electrically connected to the power amplifier module 154 and the pole plate 130, and the tuning inductor 140 is mounted in the second shielding cavity 113.

The power amplifier module 154 is configured to output a power amplifier signal, and in a thawing process, when an oscillation frequency of an oscillating circuit formed by the tuning inductor 140 and the polar plate 130 is the same as a resonance frequency carried in the power amplifier signal, food can absorb radio frequency energy radiated by the polar plate 130 to achieve a thawing purpose.

In some embodiments, the rf thawing apparatus 100 further comprises a connector 180, wherein the shielding partition 114b is provided with a connecting hole, and the connector 180 is disposed through the connecting hole.

The tuning inductor 140 and the power amplifier module 154 are mounted in the same chamber together, so that the tuning inductor 140 and the power amplifier module 154 can be directly electrically connected. Since the tuning inductor 140 and the pole plate 130 are in different chambers, the distance between the tuning inductor 140 and the pole plate 130 is far, and the difficulty of directly and electrically connecting the tuning inductor 140 and the pole plate 130 is relatively high, so as to facilitate the connection between the tuning inductor 140 and the pole plate 130, the tuning inductor 140 and the pole plate 130 can be electrically connected through the connecting piece 180.

Specifically, the connecting member 180 is disposed through the connecting hole, and one end of the connecting member 180 may be located in the first shielding cavity 112 to connect the pole plate 130, and the other end may be located in the second shielding cavity 113 to connect the tuning inductor 140, so as to electrically connect the tuning inductor 140 with the pole plate 130.

Because the shielding shell, the shielding partition 114b and the shielding cover 117 are made of metal materials, the distance between the inner wall of the connecting hole and the connecting piece 180 needs to be set at intervals, that is, the connecting piece 180 cannot be in direct contact with the inner wall of the connecting hole, so that the electric connection between the connecting piece 180 and the shielding partition 114b is avoided, and the functions of the polar plate 130 are affected.

It should be noted that, since the distance between the inner wall of the connection hole and the connection member 180 needs to be set at intervals, that is, the size of the connection hole needs to be larger than that of the connection member 180, the size of the connection hole should not be set too large, so as to avoid the influence of the power amplifier module on the rf energy of the polar plate 130. The connector 180 may employ an antenna connection tab.

Of course, in other embodiments, the tuning inductor 140 may also be mounted in the first shielding cavity 112, and of course, the tuning inductor 140 is disposed in the tuning cavity 112a. The tuning inductor 140 may be disposed near the polar plate 130 or near the second shielding cavity 113, and the tuning inductor 140 may be directly electrically connected to the polar plate 130 and the power amplifier module 154 through the connection member 180, or may be directly electrically connected to the power amplifier module 154 and the polar plate 130 through the connection member 180, which is not limited.

In some embodiments, the power amplifier module 154 includes a power amplifier circuit board, a tuning circuit board, and a control circuit board, which are integrated. I.e. the power amplifier circuit board, the tuning circuit board and the control circuit board are integrated together, thereby facilitating the installation of the power amplifier module 154 and further improving the installation convenience of the radio frequency thawing device 100.

Specifically, the integration mode may be to integrate a separate power amplifier circuit board, tuning circuit board and control circuit board together, or may set a power amplifier circuit, tuning circuit and control circuit on a circuit board, which is not limited thereto.

Of course, in other embodiments, the power amplifier module 154 may also incorporate more circuit boards. Specifically, the power amplifier module 154 includes a power amplifier circuit board, a tuning circuit board, a control circuit board, and a power circuit board, which are integrated. Similarly, the integration mode may be to integrate a separate power amplifier circuit board, tuning circuit board, control circuit board and power circuit board together, or may set a power amplifier circuit, tuning circuit, control circuit and power circuit on a circuit board, which is not limited thereto.

In some embodiments, the housing assembly 110 further includes a boss 115 protruding from the shield 114 away from the thawing chamber 113a, and the tuning chamber 112a is disposed within the boss 115.

The protruding portion 115 protrudes towards a direction away from the thawing cavity 113a so as not to occupy the space of the thawing cavity 113a, and the tuning cavity 112a is arranged in the protruding portion 115, so that more space can be reserved in the shielding piece 114 to serve as the thawing cavity 113a, the volume of the drawer assembly 120 can be increased, more food can be contained in the drawer assembly 120, further, the radio frequency thawing device 100 can thaw more food at one time, and the thawing efficiency of the radio frequency thawing device 100 is improved.

In some embodiments, the boss 115 is disposed at the bottom of the shield 114.

The polar plate 130 may be disposed in the tuning cavity 112a through a support frame, and in order to facilitate the disposition of the support frame, the tuning cavity 112a is stacked with the thawing cavity 113a, and the tuning cavity 112a is disposed below the thawing cavity 113a, so that the protruding portion 115 is disposed at the bottom of the shielding member 114.

Specifically, the protruding portion 115 is disposed on the bottom plate 1142 of the shielding main body 114c, and protrudes in a direction away from the upper cover 114 a.

In some embodiments, the boss 115 includes a mounting plate and a connecting plate that is looped around the mounting plate and connected to the shield 114 such that the mounting plate, connecting plate, and shield 114 form a tuning cavity 112a that can mount a support bracket and pole plate 130, the support bracket being secured to the mounting plate to mount the pole plate 130. The connection plates may be disposed obliquely to enhance the structural strength of the boss 115.

Specifically, the connection plate may be disposed obliquely in a direction away from the center of the mounting plate to increase the volume of the tuning cavity 112a. The shield 114, the connection plate, and the mounting plate may be integrally formed to further secure the structural strength of the boss 115.

In some embodiments, the shield 114 is provided with a connection port 114e, and the connection plate of the boss 115 is connected to the connection port 114e, i.e., the tuning chamber 112a communicates with the thawing chamber 113a through the connection port 114e, so that the plate 130 can radiate energy to the drawer assembly 120.

The connection plate of the protruding portion 115 may be connected to the edge of the connection port 114e, that is, the protruding portion 115 and the connection port 114e completely correspond to each other, the projection of the protruding portion 115 on the shielding member 114 completely coincides with the connection port 114e, and the whole tuning cavity 112a is communicated with the thawing cavity 113a, so that the energy radiated by the polar plate 130 may be maximally introduced into the thawing cavity 113a, so as to improve thawing efficiency.

Of course, in other embodiments, the projection of the boss 115 onto the shield 114 may cover the connection port 114e, so long as the tuning chamber 112a is guaranteed to communicate with the defrosting chamber 113a, and the energy radiated by the polar plate 130 may enter the defrosting chamber 113 a.

It should be noted that, the protruding portion 115 may serve as the tuning cavity 112a to accommodate the electrode plate 130, and may also serve to strengthen the structural strength of the shielding member 114, so as to reduce the occurrence probability of the magnetic leakage caused by the damage of the shielding member 114 to some extent.

The box assembly 110 further includes a partition plate, which is disposed on the connection port 114e to separate the tuning cavity 112a from the thawing cavity 113a, so that the tuning cavity 112a and the thawing cavity 113a are mutually independent, thereby realizing isolation between the polar plate 130 and food and avoiding damage to the polar plate 130 caused by water vapor generated in the thawing process of the food.

It should be noted that, since the energy radiated from the electrode plate 130 is required to enter the thawing chamber 113a through the partition plate, the partition plate cannot be made of a material having an electromagnetic shielding effect, and in particular, the partition plate may be made of plastic.
