[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0050] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0051] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0052] This application is described below with reference to the accompanying drawings and specific embodiments:

[0053] Figure 1 A schematic diagram of the structure of a refrigerator according to some embodiments of this application is shown. Figure 2 It shows Figure 1 A partial diagram of the refrigerator in the open position. Figure 3 It shows Figure 1 The diagram shows a refrigerator housing a radio frequency cooking device. (Combined with...) Figures 1-3 The refrigerator includes a cabinet 1, a door 5, and an RF cooking device 6 for defrosting and / or cooking food. The cabinet 1 has a refrigerator compartment 2, a defrosting compartment 3, and a freezer compartment 4 arranged vertically. The door 5 cooperates with the cabinet 1 to open and close the refrigerator compartment 2, defrosting compartment 3, and freezer compartment 4, respectively. Two defrosting compartments 3 can be arranged side-by-side, each capable of storing different types of food to prevent cross-contamination of odors during defrosting and / or cooking.

[0054] Combination Figure 3 In this embodiment of the application, the radio frequency cooking device 6 is arranged in the defrosting chamber 3 for defrosting and / or cooking food. Figure 4 A logic diagram of an RF cooking device is shown, combined with Figures 1-4The enclosure contains a receiving cavity 601, an RF transmitting component, and a control module 11. The receiving cavity 601 is used to store food. The RF transmitting component includes a power module 9, a power amplifier module 10, and a tuning module 61. Both the power module 9 and the power amplifier module 10 are connected to the control module 11. The power module 9 is connected to the power amplifier module 10, and the power amplifier module 10 is connected to the tuning module 61. The output of the tuning module 61 acts on the receiving cavity 601. The power module 9 supplies power to the power amplifier module 10. The control module 11 can control the output voltage of the power module 9 to the power amplifier module 10 to change the output power of the power amplifier module 10, thereby changing the radiated RF energy of the tuning module 61 to defrost and / or cook the food in the receiving cavity 601.

[0055] The radio frequency cooking device provided in this application embodiment has a storage cavity 601 that can store food, thus giving the radio frequency cooking device a storage function. Since the radiation radio frequency energy of the tuning module 61 of the radio frequency transmitting component can be changed, the food in the storage cavity 601 can be thawed and / or cooked, giving the radio frequency cooking device both thawing and cooking functions. This allows the radio frequency cooking device to integrate storage, thawing and cooking functions, making the functions more diversified, reducing space occupation, and facilitating operation in the kitchen.

[0056] In practical implementation, a control panel can be installed on the outer surface of the refrigerator body. This control panel can be located in a position that is visible and convenient for the user to operate. When any food is placed in the storage cavity 601 without operating the display panel, the refrigerator can have its original storage function. When frozen food is placed in, the display panel can be operated to defrost the food. When food that needs to be cooked is placed in, the display panel can be operated to heat the food to an edible temperature.

[0057] Of course, in other implementations, the above operations can be performed via a remote control or an app or mini-program set on a mobile terminal such as a mobile phone or tablet, and there are no restrictions here.

[0058] Figure 5 It shows Figure 3 A schematic diagram of the radio frequency cooking device in the diagram. Figure 6 It shows Figure 4 A cross-sectional schematic diagram. Combined with... Figures 5-6 The radio frequency cooking device 6 includes a cylinder 60, which is provided with a tuning cavity 602 for housing a tuning module 61 and a receiving cavity 601 for storing food to be thawed and / or cooked. When the tuning module 61 is working, the tuning module 61 generates radiation energy to thaw and / or cook the food stored in the receiving cavity 601.

[0059] Combination Figure 6A partition 62 may be provided inside the cylinder 60, which divides the cylinder into an independent tuning cavity 602 and a receiving cavity 601.

[0060] Furthermore, combined Figure 5 as well as Figure 6 The cylindrical body 60 includes a bottom plate 603, a top plate 604, and side plates 605. The side plates 605 connect the periphery of the top plate 604 and the periphery of the bottom plate 603 to form a roughly box-shaped structure. The partition 62 inside the cylindrical body 60 includes a first partition plate 621 and a second partition plate 622. The first partition plate 621 is arranged approximately horizontally. The width sides of the first partition plate 621 are respectively connected to the two side plates 605 in the width direction of the cylindrical body. The length sides of the first partition plate 621 are respectively spaced between the two side plates 605 in the length direction of the cylindrical body 60. The front side of the first partition plate 621 is connected to the bottom plate 603 via a connecting plate 623, and the rear side of the first partition plate 621 is connected to the top plate 604 via the second partition plate 622, thus enabling the tuning cavity 60... 2 includes a first chamber 6021 and a second chamber 6022. The first chamber 6021 is formed by a first partition plate 621, a connecting plate 623, and corresponding side plates 605, and is located at the bottom of the receiving cavity 601. The second chamber 6022 is formed by a second partition plate 622, a portion of a top plate 604, a portion of a bottom plate 603, and corresponding side plates 605, and is located on the side of the top of the first chamber 6021, making the tuning cavity 602 form an L-shape. The second chamber 6022 and the receiving cavity 601 are arranged side by side on the top of the first chamber 6021. The first partition plate 621, the second partition plate 622, and the connecting plate 623 can be integrally formed as a whole, or this whole can be integrally formed and connected to the cylinder to ensure the reliability of the connection.

[0061] In other embodiments, the second chamber 6022 and the receiving cavity 601 may also be arranged side by side at the bottom of the first chamber 6021, without limitation.

[0062] in addition, Figure 7 This diagram shows the state of the cylinder when it is open, combined with... Figures 5-7 The cylinder 60 is also equipped with a drawer 63, and the receiving cavity 601 (located on the front side plate 605) is provided with an inlet and outlet 6011. The drawer 63 can enter and exit the receiving cavity 601 through the inlet and outlet to facilitate the user to store and retrieve food.

[0063] Since the tuning cavity 602 contains a tuning module 61, the tuning module 61 generates radiation energy when it is working. In related technologies, a metal cylinder 60 is often used to shield the radiation energy. However, the metal cylinder 60 is formed by connecting multiple sheet metal parts, which makes the cylinder 60 prone to deformation and affects the defrosting effect of the refrigerator.

[0064] Based on this, the embodiments of this application improve the cylinder 60 to prevent deformation of the cylinder 60 to a certain extent and ensure the defrosting effect of the refrigerator.

[0065] Figure 8 Schematic diagrams of the cylinder structure in some embodiments are shown. Figure 9 It shows Figure 8 A schematic diagram of the explosion. Combined with... Figure 8 as well as Figure 9 The cylinder 60 includes a shielding component 7 and a support component 8, which are connected to each other. The shielding component 7 is used to shield the radio frequency energy emitted by the tuning module 6164. The support component 8 serves as the support part of the cylinder 60 and is used to support the shielding component 7 to prevent deformation of the shielding component 7. That is, the shielding component 7 maintains its shape under the support of the support component 8, avoiding deformation of the shielding component 7, so as to ensure the shape stability of the shielding component 7, improve the shielding effect of the shielding component 7, and correspondingly improve the defrosting effect of the refrigerator.

[0066] The support component 8 can be made of plastic, while the shielding component 7 can be made of metal. The materials of the support component 8 and the shielding component 7 are different. The support component 8 is made of low-cost plastic, which reduces the cost of the support component 8. At the same time, it ensures the supporting function of the support component 8 on the shielding component 7 and the shape stability of the shielding component 7. This solves the technical problems of poor shape stability and high cost caused by the all-metal structure of the cylinder 60.

[0067] In some implementations, the support member 8 may be disposed on the inner surface of the shielding member 7. In this case, the shielding member 7 is sleeved on the outside of the support member 8, and the shielding member 7 is supported by the support member 8. At this time, the shielding member 7 serves as the outer surface of the cylinder 60.

[0068] The support component 8 can be a single piece of molded plastic, or it can be formed by connecting multiple plastic sheets. Figure 7 as well as Figure 8 The support member 8 includes a support base plate 80 and at least one support side plate 81. The support side plate 81 is connected to one side of the support base plate 80. The support base plate 80 serves as the bottom of the support member 8 and is connected to the shielding member 7. The support base plate 80 supports the bottom of the shielding member 7 to reinforce the shielding member 7.

[0069] In some implementations, at least part of the support base plate 80 supports the shielding member 7. In this case, the lower surface of the support base plate 80 is not completely attached to the shielding member 7. That is, part of the lower surface of the support base plate 80 is attached to the shielding member 7. Part of the lower surface of the support base plate 80 can be set to be non-attached to the shielding member 7, which can also achieve the effect of the support base plate 80 supporting the shielding member 7.

[0070] The supporting side plate 81 can be disposed on one or both sides of the supporting base plate 80 in the width direction and connected to the shielding member 7, so that the supporting side plate 81 can support the side of the shielding member 7 to reinforce the shielding member 7. In this case, the bottom and the side of the shielding member 7 are both supported by the supporting member 8, so as to maintain the shape of the shielding member 7, ensure the shape stability of the shielding member 7, and improve the shielding effect of the shielding member 7.

[0071] In addition, combined Figure 8 as well as Figure 9 The support member 8 may also include a support top plate 82, which is disposed above the support bottom plate 80 and the two are disposed opposite each other. The two sides of the support bottom plate 80 and the support top plate 82 in the width direction can be connected by two support side plates 81. At this time, the support member 8 formed by the support top plate 82, the support side plates 81 and the support bottom plate 80 has a cylindrical structure that runs through the front and rear directions.

[0072] Since the top support plate 82, the side support plate 81, and the bottom support plate 80 all support the shielding component 7, each surface of the support component 8 can be attached to the shielding component 7 so that the shielding component 7 is supported in multiple directions, so as to maintain the shape of the shielding component 7, ensure the shape stability of the shielding component 7, and improve the shielding effect of the shielding component 7.

[0073] Combination Figures 7-9 The shielding component 7 in this embodiment includes a shielding cylinder 70, a shielding rear cover 71, and a shielding front frame 72. The shielding rear cover 71 and the shielding front frame 72 are located on the rear and front sides of the shielding cylinder 70, respectively, to form the aforementioned receiving cavity 601. In this embodiment, the shielding cylinder 70 is disposed outside the support member 8, meaning that the support member 8 only supports the shielding cylinder 70 and does not support the shielding rear cover 71 and the shielding front frame 72. In actual use, a shielding door 631 is provided at the outer end of the drawer 63. When the radio frequency cooking device is working, the shielding door 631 can cover the shielding front frame 72, thereby preventing radio frequency energy leakage from the tuning module 61.

[0074] The shielding cylinder 70 of this application embodiment may include multiple metal sheets connected end to end. The multiple metal sheets are respectively connected to the support member 8. At this time, the multiple metal sheets are distributed on the corresponding side walls of the support member 8 and are supported by the support member 8. Adjacent metal sheets may be welded, pressed, or integrally formed, and there is no limitation.

[0075] In other embodiments, the shielding cylinder 70 may be a metal coating applied to the support member 8, i.e., the metal coating covers the side wall of the support member 8 and is applied according to the shape of the support member 8; or, when the shielding cylinder 70 is a metal foil attached to the support member 8, the metal foil may be attached to the side wall of the support member 8 with adhesive and is attached according to the shape of the support member 8.

[0076] In other embodiments, the support member 8 can simultaneously support the shielding cylinder 70 and the shielding rear cover 71; or, the support member 8 can simultaneously support the shielding cylinder 70 and the shielding front frame 72; or, the support member 8 can simultaneously support the shielding cylinder 70, the shielding rear cover 71, and the shielding front frame 72. The support member 8 can support all of the shielding cylinder 70, the shielding rear cover 71, and the shielding front frame 72, or it can support only a portion of the shielding cylinder 70, the shielding rear cover 71, and the shielding front frame 72, which will not be elaborated here.

[0077] It should be noted that the support member 8 can also be disposed on the inner surface of the shielding member 7; or, the support member 8 can be disposed on both the outer and inner surfaces of the shielding member 7; or, the shielding member 7 can be at least partially embedded in the support member 8. In specific implementation, the above-mentioned corresponding adjustments can be referred to.

[0078] In addition, the support component 8 can also be a frame structure, that is, to support part of the shielding component 7, which can also prevent the cylinder 60 from deforming to a certain extent and ensure the defrosting effect of the refrigerator.

[0079] In related technologies, the tuning module 61 includes a plate, a tuning board 612, and a tuning inductor 613 that work together. The plate, tuning board 612, and tuning inductor 613 each have different functions and are located in different positions. Typically, the tuning inductor 613 is first installed on the tuning board 612, and then the tuning board 612 with the tuning inductor 613 installed and the plate are installed in turn in the tuning chamber. Finally, the plate and the tuning board 612 need to be electrically connected. This installation process is cumbersome, and the plate and the tuning board 612 have relatively complex installation techniques. In particular, when electrically connecting the plate and the tuning board 612, due to the limited operating space in the tuning chamber, it is difficult to ensure the consistency of the plate installation, which presents certain installation difficulties and results in low production efficiency.

[0080] To this end, in this embodiment of the application, a support frame 64 is provided in the tuning chamber, and the tuning plate 612 is divided into sections, so that the support frame 64 and the tuning inductor 613 are installed in different sections of the tuning plate 612, and the electrode plate is connected to the tuning plate 612 at the same time. By pre-assembling the tuning inductor 613, the tuning plate 612, the support frame 64 and the electrode plate, and then installing the pre-assembled whole into the tuning cavity 602, the consistency of the installation of the tuning module 61 with the electrode plate is ensured, thereby reducing the installation difficulty of the tuning module 61 and improving the assembly efficiency.

[0081] Figure 10 A schematic diagram showing the arrangement of the tuning module in the tuning room is provided. Figure 11 for Figure 10 An exploded view of the intermediate tuning module 61, combined with... Figure 10 as well as Figure 11The tuning chamber is equipped with a support frame 64, a tuning plate 612 and an electrode plate are mounted on the support frame 64, a tuning inductor 613 is mounted on the tuning plate 612, and the electrode plate can generate radiated radio frequency energy to defrost the food in the receiving cavity 601.

[0082] In practice, the food to be thawed and / or cooked is placed in the receiving cavity 601. The power amplifier module 10 of the radio frequency generation component outputs a signal to the tuning board 612, which then outputs a signal to the electrode plate. Finally, the electrode plate radiates radio frequency energy to thaw and / or cook the food. Since the tuning board 612 and the electrode plate are both mounted on the support frame 64, and the tuning inductor 613 is mounted on the tuning board 612, the tuning inductor 613, the tuning board 612, and the electrode plate can be pre-assembled with the support frame 64 to form an integral mounting component. This integral mounting component is then assembled into the tuning cavity 602 in one go, ensuring the consistency of the tuning module 61 installation. Compared to the method in related technologies where the tuning board 612 and the electrode plate are installed into the tuning cavity 602 sequentially, the method of pre-installing the tuning inductor 613, tuning board 612, support bracket 64 and electrode plate can reduce the installation difficulty of the tuning module 61, ensure the installation consistency of the tuning module 61, improve production efficiency, and facilitate the removal of the entire tuning module 61 from the tuning cavity 602 for maintenance in later maintenance work.

[0083] Combination Figure 10 Since the tuning plate 612 and the electrode plate have different functions and are located in different positions in the tuning chamber, it is necessary to install and fix the tuning plate 612 and the electrode plate at different positions on the support frame 64. Based on this, the support frame 64 may include an installation part 641 and a fixing part 642 connected to each other. The fixing part 642 of the support frame 64 can be fixed in the tuning cavity 602, while the installation part 641 can be arranged vertically on one side of the fixing part 642. The tuning plate 612 is assembled on the installation part 641 of the support frame 64, and the electrode plate is installed on the fixing part 642 of the support frame 64, so as to ensure that the tuning plate 612 and the electrode plate are placed in the required positions in the tuning chamber and achieve their respective functional effects.

[0084] It should be noted that the mounting part 641 may also have a certain angle with the fixing part 642. The specific angle can be adjusted according to the internal space of the tuning room, and there is no restriction here.

[0085] The mounting portion 641 and the fixing portion 642 of the support bracket 64 can be integrally formed or assembled after separate processing; there is no limitation on this. Compared with a support bracket 64 that is assembled after processing, the integrally formed support bracket 64 has better assembly efficiency, lower production cost, and better support stability.

[0086] Combination Figure 10The fixing part 642 in this application embodiment may include a support plate 6421. Support feet may be provided on both sides of the bottom of the support plate 6421. The support feet may be installed in the groove opened at the bottom of the tuning chamber by insertion. The mounting part 641 may be a support frame, which may be integrally formed on one side of the top of the support plate 6421.

[0087] Combination Figure 10 as well as Figure 11 In order to facilitate the installation of the electrode plate on the fixing part 642 of the support 64, the embodiment of this application may provide a first holding part 65 on the fixing part 642 (i.e., on the bearing plate 6421) of the support 64, and a second holding part 66 on the electrode plate. The first holding part 65 of the support 64 and the second holding part 66 of the electrode plate are engaged, so that the electrode plate is installed on the mounting part 641 of the support 64.

[0088] In this embodiment, the first holding part 65 may include a holding post and a holding cap 651. One end of the holding post is connected to the mounting part 641 of the support bracket 64, and the holding cap 651 is disposed at the other end of the holding post. The second holding part 66 is a holding hole disposed on the electrode plate, and the holding part passes through the holding hole. The holding cap 651 and the support bracket 64 hold the electrode plate. In implementation, the holding hole on the electrode plate can be aligned with the holding cap 651 on the mounting part 641 of the support bracket 64, and then the electrode plate can be pressed down so that the holding cap 651 passes through the holding hole, thereby causing the electrode plate to fall between the mounting part 641 of the support bracket 64 and the holding cap 651. Through the restriction of the holding cap 651, the electrode plate can be reliably assembled on the mounting part 641 of the support bracket 64.

[0089] Combination Figure 10 as well as Figure 11 In this embodiment of the application, the first holding part 65 can be integrally formed on the mounting part 641 of the support frame 64. Multiple first holding parts 65 can be provided. By using multiple first holding parts 65, the electrode plate can be prevented from rotating on the mounting part 641 of the support frame 64, thereby improving the reliability of the electrode plate being assembled on the mounting part 641 of the support frame 64.

[0090] It should be noted that the first holding part 65 and the second holding part 66 can also be reversed, that is, the first holding part 65 is set on the electrode plate, and the second holding part 66 is set on the mounting part 641 of the support frame 64. Pressing down on the electrode plate causes the holding cap 651 of the first holding part 65 on the electrode plate to pass through the mounting part 641 of the support frame 64, thereby completing the assembly of the electrode plate on the mounting part 641 of the support frame 64.

[0091] Furthermore, combined Figure 11A partition 67 may be provided on the fixing part 642 (i.e., the bearing plate 6421) of the support frame 64 at the position where the electrode plate 611 is installed. A heat dissipation part 68 may be provided on the partition 67. The electrode plate is installed on the partition 67, so that there is a gap between the electrode plate and the fixing part 642 (i.e., the bearing plate 6421) of the support frame 64, so as to facilitate heat dissipation when the electrode plate is working and improve the working life of the electrode plate.

[0092] Combination Figure 11 The partition 67 can be plate-shaped and integrally formed on the fixing part 642 (i.e., the bearing plate 6421) of the support frame 64. The heat dissipation part 68 on the partition 67 can be a heat dissipation hole or / and a heat dissipation groove, and the number can be more than one. When the heat dissipation part 68 is a heat dissipation groove, the opening of the heat dissipation groove faces the electrode plate 611 to ensure the heat dissipation effect.

[0093] The tuning inductor 613 in this embodiment includes a first connection terminal 6131, a second connection terminal 6132, and an inductor body 6133. In the tuning inductor 613, the inductor body 6133 is the main functional area, while the first connection terminal 6131 and the second connection terminal 6132 disposed at both ends of the inductor body 6133 serve as connectors for connecting the two ends of the inductor body 6133 to the tuning plate 612 and the electrode plate. Specifically, the inductor body 6133 is connected to the tuning plate 612 through the first connection terminal 6131 of the tuning inductor 613, and the inductor body 6133 is connected to the electrode plate through the second connection terminal 6132 of the tuning inductor 613, thereby meeting the setting requirements of the tuning inductor 613 in the radio frequency cooking device.

[0094] Tuning inductors 613 can generally be classified into round wire inductors and flat wire inductors. Flat wire inductors are suitable for high-power applications to ensure the usability of tuning inductor 613. Radio frequency cooking devices typically require high power to achieve their functions, and tuning inductors 613 have higher current and voltage. Therefore, in this embodiment, the tuning inductor 613 is selected as a flat wire inductor. Accordingly, the first connection terminal 6131, the second connection terminal 6132, and the inductor body 6133 of the tuning inductor 613 are all flat wires. In addition, compared to round wires, flat wires are more conducive to connecting the tuning inductor 613 to external components.

[0095] This application may provide a connecting protrusion on the tuning plate 612. The first connecting end 6131 of the tuning inductor 613 can be connected to the connecting protrusion by means of bolts, clips, etc., to realize the connection between the tuning inductor 613 and the tuning plate 612. The second connecting end 6132 of the tuning inductor 613 can be directly connected to the plate by means of bolts, clips, etc., to realize the connection between the tuning inductor 613 and the plate.

[0096] To facilitate the installation of the tuning inductor 613 within the tuning cavity 602, the extension direction of the inductor body 6133 of the tuning inductor 613 can be the same as the extension direction of the mounting portion 641. Alternatively, the extension direction of the inductor body 6133 can also be the same as the extension direction of the fixing portion 642. This reduces the space occupied by the tuning inductor 613 within the tuning cavity 602, thereby avoiding interference with other structural components of the tuning module 61.

[0097] In summary, the refrigerator provided in this application embodiment has an on-board radio frequency cooking device that integrates storage, defrosting, and cooking functions, making the functions more diverse and reducing space occupation, facilitating operation in the kitchen. Furthermore, the tuning module 61 of the radio frequency cooking device can be pre-installed, which can improve the consistency of the installation of the tuning module 61 and the assembly efficiency. In addition, the setting of plastic support parts can reduce production costs while ensuring the shielding effect, which has good practicality.
