[0004] In related technologies, the microwave generator is located on the left or right side of the cooking cavity. Because the microwave generator occupies the space on the left or right side of the cooking cavity, the size of the opening of the cooking cavity in the left-right direction is affected, which is not conducive to putting relatively large food into the cooking cavity, thereby reducing the user experience.

[0037] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0038] 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.
[0039] 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.
[0040] 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.
[0041] like Figures 1 to 5 As shown, according to an embodiment of the present invention, a cooking appliance 100 is provided, which includes a microwave device 20 and a body 10. A cooking cavity 11 is formed on the body 10, and the cooking cavity 11 has an opening 12.
[0042] In this application, both the main body 10 and the cooking cavity 11 are rectangular structures. The outer side of the cooking cavity 11 includes a front side (c), a rear side (d), a left side (e), a right side (f), a top side (a), and a bottom side (b). When the cooking appliance 100 is placed in the use position and the user faces the main body 10, the side of the cooking cavity 11 facing the user is the front side (c), the side of the cooking cavity 11 away from the user is the rear side (d), the side of the cooking cavity 11 facing the ground is the bottom side (b), the side of the cooking cavity 11 away from the ground is the top side (a), the side of the cooking cavity 11 located on the user's left hand is the left side (e), and the side of the cooking cavity 11 located on the user's right hand is the right side (f). Here, left and right refer to the arrangement direction of the left side (e) and the right side (f).
[0043] The opening 12 of the cooking cavity 11 is located on the front side c of the cooking cavity 11 and is used to take food out and put in the cooking cavity 11 through the opening 12.
[0044] The microwave device 20 is mounted on the body 10 and located inside the body 10, while the microwave device 20 is located outside the cooking cavity 11. The microwave device 20 includes a waveguide assembly 22 and a microwave generating component 21. The microwave generating component 21 is connected to the waveguide assembly 22, and the waveguide assembly 22 is connected to the side wall of the cooking cavity 11. The microwaves generated by the microwave generating component 21 are transmitted through the waveguide assembly 22 and then fed into the cooking cavity 11 (i.e., microwaves are transmitted into the cooking cavity 11) to heat and cook the food in the cooking cavity 11.
[0045] It is important to understand that the waveguide assembly 22 forms a channel structure. One end of the channel structure is connected to the microwave emitter of the microwave generating component 21, and the other end is connected to the microwave feed point of the cooking cavity 11. When the microwave generating component 21 operates, it generates microwaves. These microwaves propagate through the channel structure of the waveguide assembly 22 and are fed into the cooking cavity 11 through the microwave feed point. As the microwaves propagate within the channel structure, they do not leak through the waveguide assembly 22, thereby improving the safety performance of the cooking appliance 100 during use.
[0046] In addition, microwaves are fed into the cooking cavity 11 via waveguide component 22. When microwaves pass through waveguide component 22, the feeding position of microwaves into the cooking cavity 11 can be adjusted by setting the structure of waveguide component 22. At the same time, by setting waveguide component 22, the microwaves can be adjusted to make the microwaves more uniform, thereby improving the uniformity of microwaves fed into the cooking cavity 11.
[0047] Specifically, the microwave generating component 21 can be disposed on the rear side d, top side a, or bottom side b of the cooking cavity 11, and the waveguide assembly 22 can be disposed only on the top side a, bottom side b, left side e, right side f, or rear side d of the cooking cavity 11. The waveguide assembly 22 can also be disposed on at least two sides of the top side a, bottom side b, left side e, right side f, and rear side d of the cooking cavity 11.
[0048] like Figures 1 to 3 As shown, in this application, the microwave generating component 21 is positioned on the rear side d, left side e, right side f, top side a, or bottom side b of the cooking cavity 11. This allows the microwave generating component 21 to avoid obstructing the space in the left and right directions of the cooking cavity 11, reducing the space occupied by the microwave generating component 21 in the left and right directions of the cooking cavity 11. This increases the size of the cooking cavity 11 and the size of the opening 12 in the left and right directions, thereby meeting the user's need to place larger food items in the cooking cavity 11 and improving the user experience.
[0049] In addition, in this application, the cooking appliance 100 may also include other heating components, such as a heat radiation component 30 (e.g., a hot air component, a heating element component, or a heating plate component, etc.). The heat radiation component 30 is disposed inside the body 10 and located outside the cooking cavity 11. The heat radiation component 30 radiates heat into the cooking cavity 11 through the side wall of the cooking cavity 11 to raise the temperature of the cooking cavity 11, thereby achieving the purpose of cooking food.
[0050] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the waveguide assembly 22 includes a waveguide housing 221 and a waveguide cover 222.
[0051] Specifically, the waveguide housing 221 is a shell-shaped structure with an internal accommodating space. One side of the shell-shaped structure has an opening 2213, making the accommodating space an open structure. The accommodating space includes a first region 2211 and a second region 2212 that are connected to each other. The opening 2213 includes a first part 22131 and a second part 22132. The first part 22131 is arranged opposite to the first region 2211 (the first region 2211 communicates with the outside through the first part 22131), and the second part 22132 is arranged opposite to the second region 2212 (the second region 2212 communicates with the outside through the second part 22132).
[0052] The waveguide cover 222 is fixed on the waveguide housing 221. The waveguide cover 222 covers the first part 22131 of the opening 2213 and closes the first part 22131. The second part 22132 of the opening 2213 has an open structure. A through hole 2221 is provided on the waveguide cover 222. The through hole 2221, the first region 2211, the second region 2212 and the second part 22132 of the opening 2213 are sequentially connected to form a channel structure for microwaves to pass through.
[0053] In this microwave generating component 21, the emitter is inserted into the first region 2211 through the through hole 2221, and the second part 22132 of the opening 2213 forms the microwave feed outlet 224. When the microwave device 20 is running, the microwave emitter emits microwaves, which are transmitted through the first region 2211 to the second region 2212, and then through the second region 2212 to the microwave feed outlet 224, and then enter the cooking cavity 11 through the microwave feed outlet 224 to heat and cook the food in the cooking cavity 11.
[0054] The waveguide assembly 22 is configured into two parts: a waveguide housing 221 and a waveguide cover 222. This facilitates manufacturing and improves processing efficiency.
[0055] It should be noted that the waveguide cover 222 and the waveguide can be metal parts, and both can be processed by stamping. The connection between the waveguide cover 222 and the waveguide housing 221 includes, but is not limited to, snap-fit or connection via connectors. In addition, the connection position between the waveguide cover 222 and the waveguide housing 221 prevents microwaves from passing through, thereby reducing microwave leakage.
[0056] In some embodiments of this utility model, the microwave generating component 21 is disposed inside the body 10 and is located outside the cooking cavity 11. Specifically, the microwave generating component 21 may be disposed on the top side a or the bottom side b of the cooking cavity 11.
[0057] For example, such as Figure 1As shown, the microwave generating component 21 is located on the bottom side b of the cooking cavity 11. The microwave generating component 21 (e.g., a magnetron) is usually quite large. By placing the microwave generating component 21 on the bottom side b of the cooking cavity 11, the space occupied by the microwave generating component 21 in the left and right directions of the cooking cavity 11 can be reduced. Under the premise that the left and right dimensions of the cooking appliance 100 are fixed, the size of the cooking cavity 11 and the size of the opening 12 of the cooking cavity 11 can be increased in the left and right directions, so that users can easily put and take out larger food items in the cooking cavity 11, thereby improving the user experience.
[0058] In addition, the microwave generating component 21 is located at the bottom of the cooking cavity 11. Other power devices (such as frequency converters and electronic controllers) can also be installed at the bottom of the cooking cavity 11. By setting up a unified heat dissipation duct, heat exchange can be achieved for the power devices of the cooking appliance 100, which improves the convenience of heat dissipation duct layout, reduces the length of the heat dissipation duct, and improves the heat dissipation effect.
[0059] In some embodiments of this utility model, the waveguide assembly 22 of the microwave device 20 includes a waveguide housing 221 and a waveguide cover 222. The waveguide housing 221 and the waveguide cover 222 are connected and form a channel structure for microwaves to pass through. The emitter of the microwave generating component 21 of the microwave device 20 is disposed in the channel structure through a through hole 2221 on the waveguide cover 222 plate.
[0060] The microwave feed outlet 224 is located on the waveguide housing 221. The waveguide is positioned on the left side e or right side f of the cooking cavity 11 so that microwaves are fed into the cooking cavity 11 via the left side e or right side f. The side feeding of microwaves into the cooking cavity 11 allows the microwaves to circulate and propagate within the cooking cavity 11, enabling the microwaves to fully contact the food, thereby improving the uniformity of food heating and thus enhancing the cooking effect.
[0061] It should be understood that the waveguide housing 221 is arranged in a flat tube structure along the left and right direction of the cooking cavity 11, which can reduce the space occupied by the waveguide housing 221 in the left and right direction of the cooking cavity 11, so as to increase the volume of the cooking cavity 11 and the size of the opening 12 of the cooking cavity 11 in the left and right direction.
[0062] It should be noted that the waveguide housing 221 is connected to the outer surface of the cooking cavity 11, and the connection method includes, but is not limited to, snap-fit or connection via a connector. At the same time, the connection point between the waveguide housing 221 and the cooking cavity 11 meets the condition that microwave leakage is prevented, thereby improving the safety performance of the cooking appliance 100 during use.
[0063] In some embodiments of this utility model, such as Figures 1 to 5As shown, the microwave device 20 includes a microwave generating component 21 and a waveguide assembly 22. The waveguide assembly 22 includes a waveguide housing 221, a waveguide cover 222, and a microwave reflector 223.
[0064] Specifically, the waveguide housing 221 is a shell-shaped structure with an internal accommodating space. One side of the shell-shaped structure has an opening 2213, making the accommodating space an open structure. The accommodating space includes a first region 2211 and a second region 2212 that are connected to each other. The opening 2213 includes a first part 22131 and a second part 22132. The first part 22131 is arranged opposite to the first region 2211 (the first region 2211 communicates with the outside through the first part 22131), and the second part 22132 is arranged opposite to the second region 2212 (the second region 2212 communicates with the outside through the second part 22132). A waveguide cover 222 is fixed to the waveguide housing 221, closing the first part 22131 of the opening 2213. The second part 22132 of the opening 2213 has an open structure. A through hole 2221 is provided on the waveguide cover 222. The through hole 2221, the first region 2211, the second region 2212, and the second part 22132 of the opening 2213 are sequentially connected to form a channel structure for microwaves to pass through. The emitter of the microwave generating component 21 is inserted into the first region 2211 through the through hole 2221. The second part 22132 of the opening 2213 constitutes the microwave feed outlet 224. When the microwave device 20 is running, the microwave emitter emits microwaves, which are transmitted through the first region 2211 to the second region 2212, and then through the second region 2212 to the microwave feed outlet 224. The microwaves then enter the cooking cavity 11 through the microwave feed outlet 224 to heat and cook the food in the cooking cavity 11.
[0065] The microwave reflector 223 is disposed within the second region 2212 of the waveguide housing 221, and is positioned opposite to the microwave feed outlet 224. By using the microwave reflector 223, when microwaves travel from the first region 2211 to the second region 2212, the reflector reflects the microwaves, thereby improving the uniformity of the microwaves. This enhances the uniformity of the microwaves entering the cooking cavity 11 through the microwave feed outlet 224, ultimately improving the uniformity of microwave heating of the food and thus enhancing the cooking quality.
[0066] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the microwave reflector 223 includes reflectors, and the number of reflectors is at least one row. Each row of reflectors includes a plate 2231, and the number of plate 2231 is at least one. The plate 2231 is a flat plate structure, which is intersected with the plane where the microwave feed outlet 224 is located.
[0067] Specifically, when microwaves are transmitted from the first region 2211 of the waveguide housing 221 to the second region 2212, the plate 2231 has the function of reflecting microwaves. At the same time, microwaves can propagate along the extension direction of the plate 2231. The reflection of microwaves by the plate 2231 can improve the uniformity of microwaves. Furthermore, by setting the plate 2231, which is a flat plate structure, to intersect with the plane where the microwave feed outlet 224 is located, the microwaves propagating along the extension direction of the plate 2231 can be directed towards the microwave feed outlet 224, thereby improving the directivity of microwave propagation and thus improving the efficiency of microwave propagation.
[0068] It is important to understand that the number of reflectors can be one, two, three, four, five, six, seven, etc.
[0069] It should be noted that when there are multiple rows of reflectors, the reflectors are arranged at intervals in the arrangement direction of the first region 2211 and the second region 2212. By setting multiple rows of reflectors, the uniformity of microwaves and the efficiency of propagation are further improved.
[0070] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the microwave reflector 223 includes multiple rows of reflectors. In two adjacent rows of reflectors, the plate 2231 of one row of reflectors is staggered from the plate 2231 of the other row of reflectors.
[0071] Specifically, by setting the plates 2231 of two adjacent rows of reflectors to be staggered, the plates 2231 can all participate in the reflection of microwaves, which further improves the uniformity of microwaves and makes the heating of food by microwaves fed into the cooking cavity 11 more uniform.
[0072] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the body 10 includes a wave-transparent plate 13, which forms at least part of the sidewall of the cooking cavity 11. The waveguide housing 221 is connected to the wave-transparent plate 13, and the microwave feed outlet 224 is closed by the wave-transparent plate 13.
[0073] For example, the wave-transparent plate 13 forms part of the sidewall of the cooking cavity 11. A communication port is provided at the position of the microwave feed outlet 224 of the waveguide assembly 22 and the cooking cavity 11. The wave-transparent plate 13 (through which microwaves can pass) is connected to the outer surface of the cooking cavity 11 and the communication port is closed. The microwaves of the waveguide assembly 22 are located on the outside of the cooking cavity 11, and the waveguide housing 221 of the waveguide assembly 22 is fastened to the outer surface of the cooking cavity 11. The microwave feed outlet 224 of the waveguide assembly 22 is arranged opposite to the wave-transparent plate 13 (the shape and area of the microwave feed outlet 224 are consistent with the shape and area of the communication port) and is closed by the wave-transparent plate 13, so that the microwaves output through the microwave feed outlet 224 pass through the wave-transparent plate 13 and enter the cooking cavity 11, thereby enabling the microwaves to effectively enter the cooking cavity 11.
[0074] It should be noted that the translucent plate 13 is made of plastic or glass, etc.
[0075] In some embodiments of this utility model, the minimum distance between the top of the wave-transparent plate 13 and the microwave feed outlet 224 is a first distance, and the minimum distance between the bottom of the wave-transparent plate 13 and the microwave feed outlet 224 is a second distance, wherein the first distance is less than the second distance.
[0076] Specifically, by setting the first distance to be less than the second distance, the microwave feed outlet 224 is positioned close to the top of the cooking cavity 11, so that microwaves are fed into the cooking cavity 11 from the top, allowing the microwaves to form a surrounding structure within the cooking cavity 11. This enables heating of thicker foods while ensuring uniform heating and improving the cooking effect.
[0077] In some embodiments of this utility model, such as Figure 5 As shown, the area of the second part 22132 is larger than the area of the first part 22131.
[0078] Specifically, the shape of the first region 2211 of the waveguide housing 221 corresponds to the shape of the first part 22131, and the shape of the second region 2212 corresponds to the shape of the second part 22132. That is, when transitioning from the first region 2211 to the second region 2212, the flow cross section increases. This arrangement enables microwaves to be mixed uniformly after transitioning from the first region 2211 to the second region 2212, further improving the uniformity of microwaves.
[0079] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model 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 this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
