[0053] See also Figure 1 The radio frequency thawing device 100 and the electrical device 10 provided in the embodiment of the present application are arranged in the electrical device 10 to quickly thaw the frozen food in the electrical device 10, thereby meeting the multi-functional requirements of the electrical device 10. Figure 1 As shown, the RF thawing device 100 includes a RF generating component 150 and a tuning module. The RF generating component 150 includes a power module 152, a power amplifier module 154 and a control module 156. The power module 152, the power amplifier module 154 and the control module 156 are all electrically connected. The power module 152 is used to supply power to the power amplifier module 154 and the control module 156. The power amplifier module 154 is used to generate an initial signal of a set frequency. The control module 156 is used to control the operation of the circuits in the power module 152 and the power amplifier module 154. When it is necessary to adjust the output power of the power amplifier module 154, the control module 156 calculates a voltage regulation control instruction based on an internal algorithm and sends it to the power module 152. The power module 152 regulates the voltage to change the output voltage of the power module 152.

[0054] The power amplifier module 154 includes a signal source 154a, a power amplifier circuit 154b and a detection circuit 154c. The signal source 154a is used to generate an initial signal of a set frequency (40.68MHz); the power amplifier circuit 154b is used to amplify the power of the initial signal, enhance the power of the initial signal, and output a power amplifier signal; the detection circuit 154c is used to detect the output power of the power amplifier signal and detect the reflected power reflected back from the tuning module, and feed it back to the control module 156.

[0055] The tuning module includes a tuning inductor 140 and a plate 130, which are electrically connected to each other and to a power amplifier module 154 through the tuning inductor 140. After receiving the power amplifier signal, the tuning module radiates radio frequency energy to the food to quickly thaw the food.

[0056] In the related art, the drawer assembly 120 of the RF thawing device 100 is directly slidably connected in the shell assembly 110, and there is no locking mechanism between the drawer assembly 120 and the shell assembly 110, so that the airtightness between the drawer assembly 120 and the shell assembly 110 cannot be guaranteed when the drawer assembly 120 is completely set in the shell assembly 110, resulting in a technical problem of leakage of RF energy in the shell assembly 110.

[0057] To this end, the embodiment of the present application provides a radio frequency thawing device 100 and an electrical device 10, which can improve the above-mentioned problems. The radio frequency thawing device 100 provided in the embodiment of the present application can lock the drawer assembly 120 on the shell assembly 110 to improve the airtightness between the drawer assembly 120 and the shell assembly 110, thereby reducing the leakage of radio frequency energy, reducing harm to the human body, and reducing the impact on the thawing effect.

[0058] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0059] See also Figure 2 to Figure 8 The embodiment of the present application provides a radio frequency thawing device 100 applied to an electrical device 10. The radio frequency thawing device 100 provided in the embodiment of the present application can improve the airtightness between the drawer assembly 120 and the shell assembly 110, reduce the risk of radio frequency energy leakage during the thawing process, and improve safety and thawing effect.

[0060] like Figure 2 As shown, the radio frequency thawing device 100 includes a housing assembly 110, a drawer assembly 120, a plate 130, a first locking member 140 and a second locking member 170, wherein the housing assembly 110 has a first shielding cavity 112 and an opening 112d communicating with the first shielding cavity 112, the drawer assembly 120 includes a drawer body 121 and a door assembly 122, the drawer body 121 is movably disposed in the first shielding cavity 112, and the door assembly 122 can cover the opening The electrode plate 130 is arranged in the first shielding cavity 112, and is used to radiate radio frequency energy to the drawer assembly 120 to thaw the items to be thawed in the drawer assembly 120. The first locking member 140 is installed on the drawer assembly 120, and the second locking member 170 is installed on the shell assembly 110. Under the condition that the drawer body 121 is arranged in the first shielding cavity 112, the first locking member 140 and the second locking member 170 are locked so that the door assembly 122 closes the opening 112d.

[0061] The first shielding cavity 112 of the shell assembly 110 is used to place the items to be thawed, so the electrode plate 130 is arranged in the first shielding cavity 112 to radiate radio frequency energy to thaw the items to be thawed placed in the first shielding cavity 112. In order to facilitate the placement of the items to be thawed in the first shielding cavity 112 of the shell assembly 110, a drawer assembly 120 is arranged in the first shielding cavity 112, and in order to facilitate the placement and removal of the drawer assembly 120 in the first shielding cavity 112, an opening 112d communicating with the first shielding cavity 112 is provided on the shell assembly 110. After the items to be thawed are placed in the drawer assembly 120, the drawer assembly 120 with the items to be thawed is placed in the first shielding cavity 112 through the opening 112d on the shell assembly 110, so that the items to be thawed are placed in the first shielding cavity 112. In addition, since the objects to be thawed will generate water vapor during the thawing process, which may damage the electrode plate 130, placing the objects to be thawed in the drawer assembly 120 can reduce the impact of the water vapor generated by the objects to be thawed during the thawing process on the electrode plate 130 to a certain extent.

[0062] Since the plate 130 disposed in the first shielding cavity 112 will radiate radio frequency energy during the operation of the radio frequency thawing device 100, in order to prevent the radio frequency energy from leaking from the opening 112d of the housing assembly 110, a drawer assembly 120 is provided, including a drawer body 121 and a door assembly 122. The drawer body 121 is used to place the items to be thawed, and the drawer body 121 is movably disposed in the first shielding cavity 112 to achieve the placement and removal of the drawer body 121 in the first shielding cavity 112. The door assembly 122 is used to cover the opening 112d, so that after the drawer body 121 is placed in the first shielding cavity 112, the opening 112d is closed by the door assembly 122 to prevent the leakage of radio frequency energy.

[0063] However, if the door assembly 122 is only covered on the opening 112d of the shell assembly 110, a gap may appear between the door assembly 122 and the opening 112d, and radio frequency energy leakage may occur, which may cause harm to the human body on the one hand, and may affect the judgment of the radio frequency thawing device 100 on the thawing time on the other hand, thereby affecting the thawing effect. Therefore, a first locking member 140 is provided on the drawer assembly 120, and a second locking member 170 is provided on the shell assembly 110, so that when the drawer assembly 120 is set in the first shielding cavity 112, the first locking member 140 and the second locking member 170 are locked, so that the shell assembly 110 and the drawer assembly 120 are kept locked, so that the door assembly 122 can be kept closed on the opening 112d, and the gap between the door assembly 122 and the opening 112d is reduced, so as to improve the airtightness between the shell assembly 110 and the drawer assembly 120, reduce the risk of radio frequency energy leakage during the thawing process, and improve safety and thawing effect.

[0064] In some embodiments, Figure 3 as well as Figure 4 As shown, one of the first locking member 140 and the second locking member 170 is provided with a slot 171, and the other is provided with a protrusion 141. When the drawer body 121 is set in the first shielding cavity 112, the slot 171 and the protrusion 141 are engaged to make the door body assembly 122 close the opening 112d.

[0065] In the specific arrangement of the first locking member 140 and the second locking member 170, since the drawer body 121 needs to be frequently placed in and taken out of the housing assembly 110 to place the items to be thawed in the housing assembly 110 and to take out the items that have been thawed from the housing assembly 110, the first locking member 140 and the second locking member 170 can be locked by a snap-fitting manner, so that when the drawer body 121 is placed in the housing assembly 110, the housing assembly 110 and the drawer assembly 120 are locked, and when the drawer body 121 is taken out of the housing assembly 110, the housing assembly 110 and the drawer assembly 120 are unlocked. The first locking member 140 and the second locking member 170 are locked by snapping the protrusion 141 into the snap-fitting groove 171, so that the housing assembly 110 and the drawer assembly 120 are locked and unlocked while ensuring that the door assembly 122 seals the opening 112d of the housing assembly 110.

[0066] Among them, one of the first locking member 140 and the second locking member 170 is provided with a slot 171, and the other is provided with a convex portion 141. The slot 171 can be provided on the first locking member 140, and the convex portion 141 can be provided on the second locking member 170. Of course, the convex portion 141 can also be provided on the first locking member 140, and the slot 171 can be provided on the second locking member 170. The embodiment of the present application is not limited to this.

[0067] like Figure 4 As shown, in some embodiments, the second locking member 170 has a guide surface 172. When the drawer body 121 slides into the first shielding cavity 112, the first locking member 140 can slide relative to the guide surface 172, and after sliding into place relative to the guide surface 172, the slot 171 and the protrusion 141 engage.

[0068] The drawer body 121 of the drawer assembly 120 can be movably arranged in the first shielding cavity 112 of the shell assembly 110. Since the first locking member 140 is engaged with the second locking member 170, it is necessary to align the protrusion 141 with the slot 171 so that when the drawer body 121 is completely arranged in the first shielding cavity 112, the protrusion 141 can be accurately engaged in the slot 171.

[0069] That is, it is necessary that the guide protrusion 141 engages with the card slot 171 under the condition that the drawer body 121 moves into the first shielding cavity 112, so that the guide surface 172 is provided on the second locking member 170, so that the first locking member 140 can slide relative to the guide surface 172. When the drawer body 121 slides into the first shielding cavity 112, the first locking member 140 slides relative to the guide surface 172, so that the protrusion 141 and the card slot 171 are aligned with each other through the guidance of the guide surface 172, so that when the first locking member 140 slides into place relative to the guide surface 172, that is, when the drawer body 121 is completely disposed in the first shielding cavity 112, the protrusion 141 and the card slot 171 can be accurately engaged and connected.

[0070] In some embodiments, Figure 4 As shown, the locking groove 171 is arc-shaped, and the protrusion 141 has an arc-shaped surface 141 a , and the arc-shaped surface 141 a is engaged with the arc-shaped locking groove 171 .

[0071] The first locking member 140 and the second locking member 170 are engaged to realize locking and unlocking between the housing assembly 110 and the drawer assembly 120. In order to improve the convenience of locking and unlocking between the housing assembly 110 and the drawer assembly 120 and to be more suitable for the needs of users, the slot 171 is set to be arc-shaped, and an arc surface 141a is set on the convex portion 141, so that the arc surface 141a of the convex portion 141 is engaged with the arc-shaped slot 171. The arc structure can realize the engagement and connection between the convex portion 141 and the slot 171, and can also reduce the resistance when the convex portion 141 is connected to the slot 171 and when the convex portion 141 is pulled out of the slot 171, so that the user can realize the locking and unlocking between the housing assembly 110 and the drawer assembly 120 without using too much force.

[0072] It should be noted that, in practice, the arc structure of the protrusion 141 and the slot 171 is usually set to a micro-arc shape, so that the user can use as little force as possible to achieve locking and unlocking between the shell assembly 110 and the drawer assembly 120 while satisfying the need for locking and unlocking between the shell assembly 110 and the drawer assembly 120.

[0073] In some embodiments, Figure 5 as well as Figure 6 As shown, the first locking member 140 includes a lock hook portion 142 and a connecting portion 143 connected to each other, the connecting portion 143 is rotatably connected to the drawer assembly 120, and the locking groove 171 or the protrusion 141 is provided on the lock hook portion 142.

[0074] In order to improve the connection stability between the protrusion 141 and the slot 171, the first locking member 140 is provided to include a lock hook portion 142. The slot 171 can be provided on the lock hook portion 142, and correspondingly, the protrusion 141 is provided on the second locking member 170; or the protrusion 141 can be provided on the lock hook portion 142, and correspondingly, the slot 171 is provided on the second locking member 170. In order to enable the lock hook portion 142 to be connected to the second locking member 170, the first locking member 140 is provided to further include a connecting portion 143, the connecting portion 143 and the lock hook portion 142 are connected to each other, and the connecting portion 143 is rotatably connected to the drawer assembly 120, so that during the connection between the first locking member 140 and the second locking member 170, the protrusion 141 is extended into the slot 171 through the rotation of the connecting portion 143, and after the protrusion 141 reaches the engaging position in the slot 171, the lock hook portion 142 is hooked together with the first locking member 140 and the second locking member 170 on the basis of the engagement under the action of the rotation of the connecting portion 143.

[0075] For example, the convex portion 141 is provided on the lock hook portion 142, and the locking groove 171 is provided on the second locking member 170. In the process of inserting the lock hook portion 142 into the locking groove 171, the convex portion 141 on the lock hook portion 142 can be engaged with the locking groove 171 by rotating the connecting portion 143, and then the lock hook portion 142 is hooked on the second locking member 170 by reversely rotating the connecting portion 143.

[0076] In some embodiments, Figure 6 As shown, the first locking member 140 also includes a reset member 144, one end of which is connected to the door body assembly 122, and the other end is connected to an end of the connecting portion 143 away from the lock hook portion 142. When the lock hook portion 142 slides into place relative to the second locking member 170, the reset member 144 can provide a driving force for the protrusion 141 to engage in the slot 171.

[0077] The reset member 144 is connected between the connecting portion 143 and the door assembly 122, so that the reset member 144 provides a pressing force for the lock hook portion 142, so that during the connection process between the first locking member 140 and the second locking member 170, the connecting member rotates to stretch the reset member 144, so that the lock hook portion 142 is always pressed against the second locking member 170 until the protrusion 141 is engaged in the slot 171, and the reset member 144 provides a driving force for the protrusion 141 to be engaged in the slot 171, so as to improve the engagement stability between the protrusion 141 and the slot 171, and improve the hooking stability between the lock hook portion 142 and the second locking member 170. The reset member 144 can be a spring, rubber or other elastic structural member, which is not limited in the embodiment of the present application.

[0078] In some embodiments, Figure 3 as well as Figure 4 As shown, the RF thawing device 100 also includes an in-place detection member 180 and a controller 190. The in-place detection member 180 is installed on the housing assembly 110. The in-place detection member 180 is used to detect a locking signal of the first locking member 140 and the second locking member 170 being locked. The controller 190 is used to control the plate 130 to radiate RF energy to the drawer assembly 120 according to the locking signal and the start signal.

[0079] Through the snap connection between the first locking member 140 and the second locking member 170, the door assembly 122 can be kept closed on the opening 112d, reducing the gap between the door assembly 122 and the opening 112d to avoid leakage of radio frequency energy. In order to ensure that the plate 130 can radiate radio frequency energy only after the first locking member 140 and the second locking member 170 are snap-connected to ensure personnel safety and the normal operation of the radio frequency thawing device 100, an in-place detection member 180 and a controller 190 are provided, so that when the in-place detection member 180 detects a locking signal that the first locking member 140 and the second locking member 170 are locked, the controller 190 controls the plate 130 to radiate radio frequency energy to the drawer assembly 120 according to the locking signal and the start signal. In this way, a linkage relationship is achieved between the first locking member 140 , the second locking member 170 and the pole plate 130 , so that the pole plate 130 can radiate radio frequency energy only after the first locking member 140 and the second locking member 170 are locked.

[0080] That is, when the in-place detection member 180 detects that the first locking member 140 and the second locking member 170 are locked, the locking signal of the in-place detection member 180 is triggered, and the controller 190 receives the locking signal of the in-place detection member 180 to trigger the start signal of the controller 190. The plate 130 receives the start signal of the controller 190 and immediately starts to radiate radio frequency energy to the drawer assembly 120. In other words, the locking signal and the start signal need to be triggered at the same time to start the plate 130, thereby improving the safety and thawing effect of the radio frequency thawing device 100.

[0081] In some embodiments, Figure 4 As shown, the in-place detection member 180 includes a detector 181 and a contact piece 182 connected to the detector 181. The detector 181 is electrically connected to the controller 190. The detector 181 has a contact 181a. When the first locking member 140 and the second locking member 170 are locked, the first locking member 140 pushes the contact piece 182 to contact the contact 181a, so that the detector 181 triggers a locking signal.

[0082] In order to achieve the functional effect of the in-place detection member 180 detecting the locking signal of the first locking member 140 and the second locking member 170 being locked, the in-place detection member 180 is provided to include a detector 181 and a contact piece 182. During the locking process of the first locking member 140 and the second locking member 170, the first locking member 140 will push the contact piece 182 until the first locking member 140 and the second locking member 170 are locked, and the door body assembly 122 remains closed on the opening 112d. At this time, the first locking member 140 pushes the contact piece 182 to contact the contact 181a of the detector 181. The detector 181 detects that the first locking member 140 and the second locking member 170 are locked to trigger the locking signal of the detector 181. The controller 190 receives the locking signal to trigger the start signal. The plate 130 receives the start signal and then starts to radiate radio frequency energy to the drawer assembly 120.

[0083] That is, a mechanical structure is adopted, whereby the first locking member 140 pushes the contact piece 182 , and then the contact piece 182 contacts the contact point 181 a of the detector 181 , thereby triggering the locking signal of the in-position detection member 180 .

[0084] In some embodiments, Figure 7 As shown, the door body assembly 122 includes a panel 122a and a shielding door 122d, the panel 122a has an installation cavity 122b and a first connection port 122c connected to the installation cavity 122b, the shielding door 122d is arranged between the panel 122a and the drawer body 121, and is connected to the panel 122a and the drawer body 121, and a second connection port 122e is arranged on the shielding door 122d, which at least partially overlaps with the first connection port 122c, wherein the first locking member 140 is penetrated through the first connection port 122c and the second connection port 122e, partially arranged in the installation cavity 122b, and partially arranged outside the installation cavity 122b, for locking with the second locking member 170.

[0085] The door body assembly 122 is used to close the opening 112d of the shell assembly 110 when the drawer body 121 is completely set in the first shielding cavity 112, and the electrode plate 130 radiates radio frequency energy in the first shielding cavity 112, so that the door body assembly 122 includes a shielding door 122d, and the shielding door 122d is connected to the drawer body 121, so that when the drawer body 121 is completely set in the first shielding cavity 112, the opening 112d is closed by the shielding door 122d, so as to achieve the technical effect of shielding radio frequency energy and reducing radio frequency energy leakage, thereby improving safety and thawing effect.

[0086] In order to realize the setting of the first locking member 140 on the drawer assembly 120, the door body assembly 122 is set to also include a panel 122a. In terms of positional relationship, the shielding door 122d is set between the panel 122a and the drawer body 121. The drawer body 121, the shielding door 122d and the panel 122a are connected to each other. By setting an installation cavity 122b in the panel 122a, a part of the first locking member 140 is set in the installation cavity 122b and the remaining part is set outside the installation cavity 122b. The part of the first locking member 140 set outside the installation cavity 122b is used to connect with the second locking member 170. In order to allow the first locking member 140 to extend out of the installation cavity 122b, a first connection port 122c communicating with the installation cavity 122b is provided on the panel 122a, and a second connection port 122e is provided on the shielding door 122d, so that the first connection port 122c and the second connection port 122e at least partially overlap, so that the first locking member 140 can be simultaneously passed through the first connection port 122c and the second connection port 122e. The installation cavity 122b of the panel 122a is used to install and fix the first locking member 140, and the first locking member 140 passes through the first connection port 122c of the panel 122a and the second connection port 122e of the shielding door 122d in sequence, and is connected to the second locking member 170 provided on the housing assembly 110.

[0087] In some embodiments, Figure 7 As shown, a connection position 122f is provided in the installation cavity 122b, a rotating shaft 122g is provided at the connection position 122f, the first locking member 140 has a rotating hole 145, and the rotating shaft 122g passes through the rotating hole 145.

[0088] The first locking member 140 is rotatably connected to the drawer assembly 120, so that the first locking member 140 is conveniently connected to the second locking member 170 through the rotation of the first locking member 140. The mounting cavity 122b of the panel 122a is used for mounting and fixing the first locking member 140, so that a connecting position 122f is set in the mounting cavity 122b, and the first locking member 140 is rotatably connected to the drawer assembly 120 by inserting the rotating shaft 122g of the connecting position 122f into the rotating hole 145 of the first locking member 140. When the first locking member 140 includes a locking hook portion 142 and a connecting portion 143 connected to each other, the rotating hole 145 is set on the connecting portion 143, and the rotating shaft 122g is inserted into the rotating hole 145, so as to realize the rotatable connection between the connecting portion 143 and the drawer assembly 120.

[0089] In some embodiments, Figure 7 As shown, a sealing member 122h is disposed in the first connection port 122c, and the sealing member 122h is disposed between the first locking member 140 and the inner wall of the first connection port 122c.

[0090] Since the panel 122a is provided with a first connection port 122c and the shielding door 122d is provided with a second connection port 122e, the first connection port 122c and the second connection port 122e at least partially overlap, the RF energy in the first shielding cavity 112 may leak to the outside through the first connection port 122c and the second connection port 122e. Furthermore, since the first locking member 140 is simultaneously provided at the first connection port 122c and the second connection port 122e, the radio frequency energy may leak to the outside through the gap between the first locking member 140 and the first connection port 122c and the second connection port 122e, so it is necessary to set a sealing member 122h between the first locking member 140 and the first connection port 122c and the second connection port 122e. Considering that the first locking member 140 is rotatably connected to the drawer assembly 120, if the sealing member 122h is set between the first locking member 140 and the second connection port 122e, the rotation of the first locking member 140 may be hindered, so the sealing member 122h is set between the first locking member 140 and the inner wall of the first connection port 122c.

[0091] In some embodiments, Figure 2 As shown, the shell assembly 110 includes a fixing bracket 116 and a box assembly 117 , the first shielding cavity 112 is disposed in the box assembly 117 , the fixing bracket 116 is disposed outside the first shielding cavity 112 and fixedly connected to the box assembly 117 , and the second locking member 170 is disposed on the fixing bracket 116 .

[0092] In the specific configuration of the housing assembly 110, the housing assembly 110 includes a fixing bracket 116 and a box assembly 117, wherein a first shielding cavity 112 is provided inside the box assembly 117, and the box assembly 117 constitutes the main shielding structure of the housing assembly 110. After the box assembly 117 is connected to the shielding door 122d, a sealed first shielding cavity 112 is formed inside to isolate radio frequency energy. The fixing bracket 116 is arranged outside the first shielding cavity 112, and the fixing bracket 116 is fixedly connected to the box assembly 117, so that the second locking member 170 is installed and fixed through the fixing bracket 116, and the overall structure of the box assembly 117 is reinforced.

[0093] Of course, the second locking member 170 may also be disposed on the box assembly 117 to provide an installation base for the second locking member 170 through the box assembly 117 .

[0094] In some embodiments, Figure 8 As shown, the RF thawing device 100 further includes a slide rail assembly 160 , which is installed in the first shielding cavity 112 and slidably connected to the drawer body 121 . The slide rail assembly 160 is fixedly connected to the fixed bracket 116 and the box assembly 117 .

[0095] The drawer body 121 is movably disposed in the first shielding cavity 112, and by installing the slide rail assembly 160 in the first shielding cavity 112, the drawer body 121 is slidably connected to the slide rail assembly 160, so that the drawer body 121 can slide in the first shielding cavity 112, and the sliding direction of the drawer body 121 can be limited by the slide rail assembly 160 to ensure the alignment of the protrusion 141 and the card slot 171. In addition, in order to improve the installation stability of the slide rail assembly 160, the slide rail assembly 160 is fixedly connected to the fixed bracket 116 and the box assembly 117 to form an integral structure.

[0096] The weight of the drawer assembly 120 and the weight of the items to be thawed will be transferred to the slide rail assembly 160, and at least most of the force applied to the slide rail assembly 160 will be transferred to the fixed bracket 116. The fixed bracket 116 becomes the force-bearing body, and the connection between the box assembly 117 and the fixed bracket 116 is no longer subjected to force or is subjected to little force. Therefore, the pressure at the connection between the box assembly 117 and the fixed bracket 116 will be greatly reduced, and the probability of plastic deformation will also be greatly reduced.

[0097] After the connection between the box assembly 117 and the fixed bracket 116 is not easily deformed, the relative position of the box assembly 117 and the slide rail assembly 160 is not easily changed, the box assembly 117 and the slide rail assembly 160 can still maintain their initial shape after multiple uses, and the shielding effect of radio frequency energy is good. The drawer assembly 120 is not easy to get stuck during the sliding in or out process due to the deformation of the box assembly 117 or the slide rail assembly 160, and the user experience is good.

[0098] In some embodiments, Figure 2 as well as Figure 8 As shown, the slide rail assembly 160 and the fixing bracket 116 clamp the box assembly 117 .

[0099] The fixed bracket 116 can reinforce the overall structure of the box assembly 117, and the slide rail assembly 160 is fixedly connected to the fixed bracket 116 and the box assembly 117 at the same time. Considering that the structural strength of the box assembly 117 is lower than the structural strength of the fixed bracket 116, the box assembly 117 is clamped between the slide rail assembly 160 and the fixed bracket 116, so that the slide rail assembly 160 is mainly supported by the fixed bracket 116, thereby improving the structural strength of the shell assembly 110 as a whole.

[0100] After the box assembly 117, the fixed bracket 116 and the slide rail assembly 160 are connected, the box assembly 117 is set on the fixed bracket 116. At this time, the fixed bracket 116 has the function of supporting the box assembly 117. When the inner wall and the outer wall of the box assembly 117 are in contact with and close to the slide rail bracket 164 and the fixed bracket 116 respectively, the box assembly 117 is clamped by the fixed bracket 116 and the slide rail assembly 160, and the gravity of the box assembly 117 is transferred to the fixed bracket 116, so that the box assembly 117 is not easy to deform.

[0101] At the same time, after the inner wall and outer wall of the box assembly 117 are in contact with and tightly attached to the slide rail assembly 160 and the fixed bracket 116 respectively, the contact area between the outer wall of the box assembly 117 and the fixed bracket 116 and the contact area between the inner wall of the box assembly 117 and the slide rail assembly 160 increase, and the stress from the slide rail assembly 160 and the stress of the box assembly 117 are both dispersed, the pressure on the box assembly 117 becomes smaller, and it is not easy to deform.

[0102] In some embodiments, Figure 7 As shown, the housing assembly 110 further comprises a second shielding cavity 113 , and the radio frequency thawing device 100 further comprises a power amplifier module 154 , which is disposed in the second shielding cavity 113 .

[0103] The drawer assembly 120 and the pole plate 130 are arranged in the first shielding cavity 112 of the box assembly 110, and the power amplifier module 154 is arranged in the second shielding cavity 113 of the box assembly 110, that is, the drawer assembly 120, the pole plate 130 and the power amplifier module 154 are all arranged in the box assembly 110, so that the radio frequency thawing device 100 forms a whole, so that the radio frequency thawing device 100 is more convenient to install and the installation cost is lower.

[0104] Furthermore, the first shielding cavity 112 and the second shielding cavity 113 are independent of each other in the box assembly 110, so that even if the drawer assembly 120, the pole plate 130 and the power amplifier module 154 are all arranged in the box assembly 110, the influence of the power amplifier module on the radio frequency energy of the pole plate 130 can be avoided to a certain extent, and the power amplifier module 154 and the pole plate 130 will not interfere with each other.

[0105] Since the power amplifier module 154 includes a variety of electronic components, the water vapor generated during the thawing process of the items to be thawed may also damage the power amplifier module 154. Therefore, the power amplifier module 154 is arranged in the second shielding cavity 113 to isolate the items to be thawed and the power amplifier module 154 from each other, so as to prevent the water vapor generated during the thawing process of the items to be thawed from affecting the power amplifier module 154.

[0106] In some embodiments, Fig. 9As shown, the first shielding cavity 112 includes a thawing cavity 112b and a tuning cavity 112a, the drawer assembly 120 is arranged in the thawing cavity 112b, the pole plate 130 is arranged in the tuning cavity 112a, the shell assembly 110 includes a shielding member 114 having the thawing cavity 112b and a protrusion 115 protruding from the shielding member 114 away from the thawing cavity 112b, and the tuning cavity 112a is arranged in the protrusion 115.

[0107] In order to avoid interference between the drawer body 121 and the pole plate 130, the first shielding cavity 112 is provided to include a thawing cavity 112b and a tuning cavity 112a, the drawer assembly 120 is provided in the thawing cavity 112b, the pole plate 130 is provided in the tuning cavity 112a, and the thawing cavity 112b is located in the shielding member 114, while the tuning cavity 112a is located in a raised portion 115 which is away from the thawing cavity 112b and protrudes from the shielding member 114, the raised portion 115 provides an installation space for the pole plate 130, so that the thawing cavity 112b and the tuning cavity 112a are independent of each other, and when the drawer body 121 is completely provided in the thawing cavity 112b, the pole plate 130 is located on one side of the drawer body 121, and no interference occurs between the drawer body 121 and the pole plate 130.

[0108] The raised portion 115 protrudes in a direction away from the thawing chamber 112b so as not to occupy the space of the thawing chamber 112b. The tuning chamber 112a is arranged in the raised portion 115, so that more space can be reserved in the shielding member 114 for use as the thawing chamber 112b, thereby increasing the volume of the drawer assembly 120, so that more food can be accommodated in the drawer assembly 120, and the RF thawing device 100 can thaw more food at one time, thereby improving the thawing efficiency of the RF thawing device 100.

[0109] To summarize, the first locking member 140 is rotatably disposed on the drawer assembly 120, and the second locking member 170 is fixedly disposed on the shell assembly 110. In the process of disposing the drawer assembly 120 in the shell assembly 110, the first locking member 140 slides along the second locking member 170, and under the action of the reset member 144, the first locking member 140 always maintains a clamping force on the second locking member 170 until the drawer assembly 120 is completely disposed in the shell assembly 110. The first locking member 140 is engaged with the second locking member 170, the protrusion 141 is engaged in the slot 171, and the lock hook portion 142 is hooked on the second locking member 170, thereby realizing the locking between the shell assembly 110 and the drawer assembly 120, thereby improving the airtightness between the drawer assembly 120 and the shell assembly 110.

[0110] Based on the same inventive concept, please refer to Fig.10The embodiment of the present application provides an electrical device 10, including a main body 200 and the above-mentioned radio frequency thawing device 100, the main body 200 has a receiving cavity 210, and the radio frequency thawing device 100 is arranged in the receiving cavity 210. Among them, the main body 200 is the basic component of the refrigerator of the present application, and the main body 200 can provide an installation foundation for at least part of other components of the refrigerator, and can also serve the purpose of protecting at least part of other components of the refrigerator.

[0111] The electrical device 10 may be a refrigerator, wherein the main body 200 has a freezing chamber, a refrigerating chamber and a temperature-variable chamber, and the accommodating cavity 210 may be disposed in any one of the freezing chamber, the refrigerating chamber and the temperature-variable chamber.

[0112] The accommodating chamber 210 has an air duct 220, and the tuning chamber 112a has an air inlet and an air outlet connected to the air duct 220, so that an air circulation is formed among the air duct 220, the air inlet, the air outlet and the thawing chamber 112b. During the flow of air, the heat in the thawing chamber 112b can be continuously taken away, thereby reducing the temperature in the tuning chamber 112a, avoiding damage to the tuning module caused by high temperature to a certain extent, and ensuring the performance of the tuning module.

[0113] In some embodiments, Fig. 9 as well as Fig.10 As shown, the protrusion 115 is arranged in the air duct 220, so that when the protrusion 115 is arranged on the shielding member 114, the original installation space of the shielding member 114 in the accommodating cavity 210 will not be occupied, and the protrusion 115 is directly arranged in the air duct 220, which can also enhance the heat dissipation effect of the tuning cavity 112a.

[0114] In some embodiments, Fig. 9 as well as Fig.10 As shown, the protrusion 115 is spaced apart from the inner wall of the air duct 220 to ensure that air flows between the protrusion 115 and the inner wall of the air duct 220, thereby ensuring that the heat in the tuning cavity 112a is taken away by the air.
