Description

Technical Field

[0001] This invention belongs to the field of cooking equipment technology, and specifically relates to a cooking device. Background Technology

[0002] An interlocking assembly is a protective device that controls the power supply to the entire microwave oven based on the opening and closing of the oven door, ensuring that the microwave oven cannot operate normally when the door is open. For current microwave ovens and their combination models, the interlocking assembly is generally installed as a single component on one side of the cavity. Because it is directly mounted on the front panel or placed on the side of the cavity, it needs to be assembled during the final assembly process, and the wiring process after installing the interlocking assembly also needs to be completed during final assembly. Secondly, for products with grilling or hot air functions, the location of the interlocking assembly is in direct contact with the metal cavity, resulting in very rapid heat conduction. Since the microswitches on the interlocking assembly cannot withstand high temperatures, separate heat dissipation is required to cool it down. Summary of the Invention

[0003] The object of this invention is to at least solve the problem of the interlocking assembly being located on the side of the cavity, affecting assembly. This object is achieved by the following means:

[0004] This invention proposes a cooking apparatus, the cooking apparatus comprising:

[0007] An interlocking assembly is connected to the base plate body and is disposed between the cavity and the base plate body.

[0008] According to the cooking apparatus of the present invention, by placing the interlocking assembly between the cavity and the base plate body and connecting it to the base plate body, the interlocking assembly can be connected to the base plate body as a whole before being installed at the bottom of the cavity during assembly. This facilitates the assembly of the interlocking assembly and the wiring of the interlocking assembly. At the same time, placing the interlocking assembly at the bottom of the cavity avoids the interlocking assembly occupying the side space of the cavity, thereby further increasing the volume of the cavity and improving the heating efficiency of the cooking apparatus.

[0040] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0041] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0042] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0043] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0044] This application discloses a cooking apparatus, which can be a microwave oven, oven, steamer, or a cooking device with two or more heating functions simultaneously. For ease of description, this embodiment will only describe the cooking apparatus as a microwave oven.

[0045] Combination Figures 1 to 3 As shown, the cooking apparatus 1 of this embodiment includes a cavity 50, a base plate assembly, and an interlocking assembly 20. The cavity 50 provides space for cooking food. An opening is provided at the front end of the cavity 50, and a door 40 is provided at the opening. The cavity 50 can be opened or closed by operating the door 40. The base plate assembly includes a base plate body 10, which is located below and spaced apart from the cavity 50. The base plate body 10 includes a base 11 and a cover plate 12. The cover plate 12 covers the base 11 and forms a receiving cavity (not shown in the figure) with the base 11. A power board is located within the receiving cavity. The interlocking assembly 20 is connected to the top of the cover plate 12 and is located between the cavity 50 and the base plate body 10. The interlocking assembly 20 is also electrically connected to the power board, which supplies power to the interlocking assembly 20, thereby controlling the opening and closing of the circuit.

[0046] According to the cooking apparatus 1 of the present invention, by placing the interlocking assembly 20 between the cavity 50 and the base plate body 10 and connecting it to the base plate body 10, the interlocking assembly 20 can be connected to the base plate body 10 as a whole before being installed at the bottom of the cavity 50, thus facilitating the assembly of the interlocking assembly 20. Simultaneously, by placing the power board in the receiving cavity, it is convenient to pre-connect the interlocking assembly 20 to the power board and supply power to it via the power board, avoiding the need for wiring the interlocking assembly 20 during final assembly, reducing the complexity of the final assembly process and improving assembly efficiency. Furthermore, placing the interlocking assembly 20 at the bottom of the cavity avoids the interlocking assembly 20 occupying the side space of the cavity 50, thereby further increasing the volume of the cavity 50 and improving the heating efficiency of the cooking apparatus 1.

[0047] Furthermore, the cavity in this embodiment also includes at least one of a filter board, a frequency converter, a transformer, and a microwave generating module. It should be noted that the frequency converter and transformer in the electrical components specifically designed for microwave cooking appliances are optional; the former is suitable for variable frequency microwave cooking appliances, and the latter is suitable for fixed frequency microwave cooking appliances. Additionally, it is understood that the microwave generating module can have different structures depending on the different microwave generation principles. For example, for magnetron-type microwave cooking appliances, the microwave generating module may include a magnetron and a waveguide, while for semiconductor-type microwave cooking appliances, the microwave generating module may include a semiconductor microwave generator.

[0048] The base plate assembly 10 of this embodiment not only provides support for the entire cooking device 1, but also provides mounting positions for the electrical components of the cooking device 1, so that the electrical components and the base plate body 10 are integrated together. This changes the situation where the electrical components of the existing cooking device 1 are installed in different parts of the whole machine. This helps to reduce the number of installation modules in the cooking device 1 during the assembly process, thereby improving assembly efficiency.

[0049] Specifically, the cooking apparatus of this embodiment can be a microwave oven, a microwave oven combo, or other cooking appliance with microwave heating function. For example, in one specific example, a power board, a filter board, a frequency converter (or transformer), and a semiconductor microwave generator are arranged in the receiving cavity. In another specific example, a power board and a filter board are arranged in the receiving cavity. In yet another different example, a power board and a frequency converter (or transformer) are arranged in the receiving cavity. It is understood that in other examples, the electrical components arranged in the receiving cavity can be various combinations including a semiconductor microwave generator, which will not be listed here.

[0050] Furthermore, in other embodiments of this application, a water pump and / or a steam generator are also provided in the receiving cavity. Correspondingly, the cooking device 1 can be a cooking appliance with steam function, such as a steam oven or a steam-oven combination appliance. For example, in one specific example, a power board, a water pump, and a steam generator are provided in the receiving cavity. In another specific example, a power board and a water pump are provided in the receiving cavity. In yet another different example, a power board and a steam generator are provided in the receiving cavity.

[0051] Furthermore, in other embodiments of this application, when the cavity is simultaneously provided with at least one of a filter board, a frequency converter, a transformer, and a microwave generating module, at least one of a water pump and a steam generator, and a power board, the corresponding cooking device can be a microwave-steam combo cooker, an oven-microwave-steam combo cooker, or other cooking appliances that have both microwave and steam functions.

[0052] Furthermore, in this embodiment, the base plate body 10 is an insulating component, such as a plastic or ceramic component. Plastic components possess excellent insulation properties, meeting electrical safety requirements. Additionally, plastic components are easy to process and mold, have low cost, and are resistant to drops and impacts. Ceramic components also possess excellent insulation properties, as well as advantages such as high gloss and wear resistance. It is understood that the base plate body 10 is not limited to using plastic or ceramic components; it can also be made of insulating materials such as glass or mica. By installing the electrical components of the cooking device 1 within a cavity made of an insulating component, electrical safety requirements can be effectively met, thereby eliminating the need for a separately installed insulating box, reducing the number of parts in the entire machine, and consequently lowering production costs and improving production efficiency.

[0053] Furthermore, combined Figures 4 to 9As shown, the interlocking assembly 20 of this embodiment includes at least one interlocking lever and at least one micro switch. The interlocking lever and the micro switch are both disposed on the cover plate 12 and spaced apart from the cavity 50. The interlocking lever controls the micro switch to open or close in a manner that allows it to move relative to the micro switch. Specifically, the at least one interlocking lever in this embodiment includes a first interlocking lever 21 and a second interlocking lever 22. Both the first interlocking lever 21 and the second interlocking lever 22 are rotatably disposed directly on the cover plate 12. Specifically, the first interlocking lever 21 is connected to the cover plate 12 via a first spring 26, and the second interlocking lever 22 is connected to the cover plate 12 via a second spring 27, thereby driving the first interlocking lever 21 and the second interlocking lever 22 to rotate under the deformation force of the first spring 26 and the second spring 27. At least one microswitch includes a first microswitch 23, a second microswitch 24, and a third microswitch 25. A first interlocking lever 21, during rotation, can contact the contacts of the first microswitch 23 and the second microswitch 24, thereby turning the first microswitch 23 and the second microswitch 24 on or off. A second interlocking lever 22, during rotation, can contact the contact of the third microswitch 23, thereby turning the third microswitch 23 on or off. Specifically, when the first interlocking lever 21 contacts the contact of the second microswitch 24, the main circuit is activated. When the first interlocking lever 21 contacts the contact of the first microswitch 23, the monitoring system is activated. When the second interlocking lever 22 contacts the contact of the third microswitch 25, the main control board sends a start signal, and the heating function can be activated normally.

[0054] In this embodiment, the first interlocking lever 21, the second interlocking lever 22, the first micro switch 23, the second micro switch 24, and the third micro switch 25 are all directly mounted on the cover plate 12, thereby reducing the need for interlocking brackets and the overall thickness of the interlocking components. This allows for a further increase in the volume of the cavity 50, improving the cooking efficiency of the cooking device 1. Simultaneously, the first interlocking lever 21, the second interlocking lever 22, the first micro switch 23, the second micro switch 24, and the third micro switch 25 are spaced apart from the bottom of the cavity 50. The heat generated by the cavity during operation of the cooking device 1 is not directly conducted to the first micro switch 23, the second micro switch 24, and the third micro switch 25, effectively reducing the temperature rise of these switches. This further reduces the need for fans to dissipate heat from the first micro switch 23, the second micro switch 24, and the third micro switch 25, reducing the number of parts and improving the assembly efficiency of the cooking device 1.

[0055] Specifically, in combination Figures 3 to 9As shown, the first interlocking lever 21 and the second interlocking lever 22 in this embodiment are generally T-shaped. One end of the first interlocking lever 21 has a first insertion end 212, and one end of the second interlocking lever 22 has a second insertion end 222. Correspondingly, the front plate 30 of the cooking device 1 has a first mounting hole and a second mounting hole. The first insertion end 212 of the first interlocking lever 21 is inserted into the first mounting hole and can move along the axial direction of the first mounting hole. The second insertion end 222 of the second interlocking lever 22 is inserted into the second mounting hole and can move along the axial direction of the second mounting hole. In this embodiment, the door 40 is retractable and located at the front end of the front panel 30. When the door 40 is opened, the first insertion end 212 extends out of the first mounting hole, and the second insertion end 222 extends out of the second mounting hole. When the door 40 is closed, the first insertion end 212 and the second insertion end 222 abut against the door 40 and move along the axial direction of the first and second mounting holes in the direction of closing the door 40 under the action of the door body, thereby driving the first interlocking lever 21 and the second interlocking lever 22 to rotate. The other two ends of the first interlocking lever 21 serve as the first protruding end 213 and the second protruding end 214, respectively. The first protruding end 213 is used to press the contacts on the first micro switch 23, and the second protruding end 214 is used to press the contacts on the second micro switch 24. At the same time, the first protruding end 213 is connected to the cover plate 12 through the first spring 26. The other two ends of the second interlocking lever 22 serve as the third protruding end 223 and the fourth protruding end 224, respectively. The third protruding end 223 is used to press the contacts on the third micro switch 25, and the fourth protruding end 224 is connected to the cover plate 12 through the second spring 27.

[0056] In other embodiments of this application, the door 40 may also be disposed at the front end of the cavity 50 in a flip-open or side-opening manner, such as... Figure 12 and Figure 13 As shown, during the closing process of the door 40, the first interlocking lever 21 and the second interlocking lever 22 can be driven to rotate by abutting against the first plug-in end 212 and the second plug-in end 222, thereby controlling the opening or closing of the microwave function.

[0057] In other embodiments of this application, a first plug-in end and a second plug-in end may be provided on the door body 40. Correspondingly, the first plug-in end and the second plug-in end on the first interlocking lever 21 and the second interlocking lever 22 may be eliminated. When the door body 40 is open, the first plug-in end separates from the first interlocking lever 21, and the second plug-in end separates from the second interlocking lever 22. When the door body 40 is closed, the first plug-in end passes through the first mounting hole and abuts against the first interlocking lever 21, thereby driving the first interlocking lever 21 to rotate. At the same time, the second plug-in end passes through the second mounting hole and abuts against the second interlocking lever 22, thereby driving the second interlocking lever 22 to rotate, thereby controlling the opening or closing of the microwave function.

[0058] Since the interlocking assembly 20 in this embodiment is located on the cover plate 12, it does not require support from the front plate 30. Therefore, the support strength of the front plate 30 can be appropriately reduced, i.e., the thickness of the front plate 30 can be decreased, thereby further increasing the volume of the cavity 50. Simultaneously, since the interlocking assembly 20 in this embodiment is located at the bottom of the cavity 50, there is no need to open mounting holes on the side of the front plate 30, thus improving the appearance of the front plate 30.

[0059] Specifically, in this embodiment, the first microswitch 23 and the third microswitch 25 are normally open, and the second microswitch 24 is normally closed. When the door 40 is opened, the door 40 separates from the first plug-in end 212 and the second plug-in end 222, with the first plug-in end 212 and the second plug-in end 222 extending outside the mounting hole. The interlocking assembly 20, as shown... Figure 6 In the indicated state, the first protruding end 213 is separated from the contact of the first micro switch 23, the second protruding end 214 is separated from the contact of the second micro switch 24, and the third protruding end 223 is separated from the contact of the third micro switch 25. The microwave function of the cooking device 1 cannot be activated. When the door 40 is closed, the door 40 simultaneously abuts against the first insertion end 212 and the second insertion end 222, driving the first interlocking lever 21 to rotate and the second interlocking lever 22 to rotate. The interlocking assembly 20... Figure 8 As shown, the first protruding end 213 is in contact with the first micro switch 23, the second protruding end 214 is in contact with the contact of the second micro switch 24, and the third protruding end 223 is in contact with the contact of the third micro switch 25. The microwave function of the cooking device 1 is started normally, thereby heating the food in the cavity 50.

[0060] Specifically, in this embodiment, the diameter of the first mounting hole is larger than the diameter of the first insertion end 212. The first insertion end 212 moves along the axial direction of the first mounting hole while rotating, thus changing the angle between the axial direction of the first insertion end 212 and the axial direction of the first mounting hole. The diameter of the second mounting hole is larger than the diameter of the second insertion end 222. The second insertion end 222 moves along the axial direction of the second mounting hole while rotating, thus changing the angle between the axial direction of the second insertion end 222 and the axial direction of the second mounting hole.

[0061] Combined Figures 9 to 11 As shown, in this embodiment, the cover plate 12 is provided with a first support shaft 121 and a second support shaft 122 spaced apart. Correspondingly, the first interlocking lever 21 is provided with a first connecting hole 211, and the second interlocking lever 22 is provided with a second connecting hole 221. The first connecting hole 211 is sleeved on the outside of the first support shaft 121, thereby realizing the rotation of the first interlocking lever 21 on the cover plate 12. The second connecting hole 221 is sleeved on the outside of the second support shaft 122, thereby realizing the rotation of the second interlocking lever 22 on the cover plate 12. Furthermore, the cover plate 12 in this embodiment is also provided with a first fixed end 123 and a second fixed end 124. The two ends of the first spring 26 are respectively connected to the first fixed end 123 and the first extended end 213, and the two ends of the second spring 27 are respectively connected to the second fixed end 124 and the third extended end 223. When the door 40 is closed, pressing the first plug-in end 212 causes the first interlocking lever 21 to rotate and compress the first spring 26, causing it to deform and engage with the first micro switch 23 and the second micro switch 24. When the door 40 is opened, it separates from the first plug-in end 212, and the first interlocking lever 21 rotates under the elastic restoring force of the first spring 26, thus separating it from the first micro switch 23 and the second micro switch 24. Similarly, the working state of the second spring 27 is consistent with that of the first spring 26, and will not be described further here.

[0062] Furthermore, the cover plate 12 of this embodiment is also provided with six connecting posts 125. The six connecting posts 125 are arranged in pairs opposite each other to form a group. Two connecting posts 125 in a group are used to fix the same micro switch. The micro switch is provided with a fixing hole that matches the connecting post 125. The connecting post 125 is inserted into the fixing hole and fixes the micro switch.

[0063] Furthermore, in other embodiments of this application, the interlocking assembly 20 also includes an interlocking bracket, on which the interlocking lever and the micro switch are mounted, and the interlocking bracket is connected to the top of the cover plate 12. By providing the interlocking bracket, the interlocking lever and the micro switch can be pre-assembled with the interlocking bracket, and then the entire interlocking assembly 20 can be installed on the cover plate 12 via the interlocking bracket, thereby further improving the assembly efficiency of the cooking device 1 and facilitating the disassembly of the entire interlocking assembly 20.

[0064] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
