Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and more particularly, to a cooking appliance. Background Art

[0002] At present, microwave ovens in related technologies generally use a standing wave field to heat food ingredients relying on hot spots. Since the cold and hot spots of the standing wave are fixed, the uniformity of food ingredient cooking is poor, affecting the cooking effect of food ingredients. Summary of the Invention

[0003] Embodiments of the present invention aim to at least solve one of the technical problems existing in the prior art.

[0004] To this end, a first aspect of embodiments of the present invention provides a cooking appliance.

[0005] In view of this, according to a first aspect of embodiments of the present invention, there is provided a cooking appliance, the cooking appliance comprising: an appliance body provided with a cooking cavity; a waveguide assembly provided on the appliance body and located outside the cooking cavity, the waveguide assembly including an installation cavity, a plurality of reflection fins and a first microwave channel, the plurality of reflection fins being located in the installation cavity and arranged at intervals, one end of the first microwave channel communicating with the installation cavity; a magnetron provided on the waveguide assembly, the other end of the first microwave channel communicating with the magnetron, and the microwave generated by the magnetron being capable of being fed into the cooking cavity in sequence through the first microwave channel and the installation cavity.

[0006] The cooking appliance provided by embodiments of the present invention includes an appliance body, a waveguide assembly and a magnetron. Specifically, the appliance body is provided with a cooking cavity. It can be understood that by placing food ingredients in the cooking cavity and starting the cooking appliance, the food ingredients in the cooking cavity can be cooked using microwaves.

[0007] The waveguide assembly is provided on the appliance body, the magnetron is provided on the waveguide assembly, one end of the first microwave channel communicates with the installation cavity, and the other end communicates with the magnetron. It can be understood that the magnetron can generate microwaves, and the microwaves are fed into the cooking cavity through the first microwave channel and the installation cavity.

[0008] The waveguide assembly includes a plurality of reflection fins, and the plurality of reflection fins are arranged at intervals in the installation cavity. It can be understood that the reflection fins can reflect microwaves. That is to say, before the microwaves are fed into the cooking cavity, the microwaves are multiply reflected by the plurality of reflection fins to excite traveling waves, realizing the periodic crawling of the thermal field of the microwaves in the cooking cavity, exciting a uniform electromagnetic field, avoiding the thermal field being fixed in a specific area in the cooking cavity, being beneficial to improving the uniformity of food ingredient cooking, and further improving the cooking effect of food ingredients.

[0009] Moreover, by arranging a plurality of reflection fins in the installation cavity, the amplitude of the microwave is increased after crawling through the plurality of reflection fins, so that the heating height of the microwave on the food materials can be increased. At the same time, it can also play a guiding role for the microwave.

[0010] In addition, since the plurality of reflection fins are arranged in the installation cavity, that is to say, the plurality of reflection fins are integrated in the waveguide assembly. Compared with integrating the plurality of reflection fins in other areas of the cooking cavity, the integration of the microwave transmission and excitation system is improved, the number of parts is reduced. At the same time, the waveguide and the reflection fin are modularized, reducing the material requirements of the cooking cavity, thereby reducing the processing cost, welding cost, transportation cost and the risk of deformation during transportation of the parts of the cooking appliance, and further reducing the production cost of the cooking appliance.

[0011] Optionally, the cooking appliance includes a microwave oven, a microwave and grill combination oven or a microwave, steam and grill combination oven.

[0012] In addition, the cooking appliance provided by the above technical solution of the present invention further has the following additional technical features:

[0013] In some technical solutions, optionally, at least two reflection fins are arranged at intervals along a first direction, and the first direction includes the direction from the first microwave channel to the installation cavity.

[0014] In this technical solution, since at least two reflection fins are arranged at intervals along the direction from the first microwave channel to the installation cavity, the microwave can crawl on at least two reflection fins, thereby increasing the amplitude of the microwave fed into the cooking cavity, and further improving the cooking effect on the food materials.

[0015] In addition, the microwave generated by the magnetron flows through the first microwave channel to the installation cavity, and before being fed into the cooking cavity, it will flow through a plurality of reflection fins, thereby performing multiple reflections on the microwave, exciting traveling waves, realizing the periodic crawling of the thermal field of the microwave in the cooking cavity, exciting a uniform electromagnetic field, avoiding the thermal field being fixed in a specific area of the cooking cavity, being beneficial to improving the uniformity of food material cooking, and further improving the cooking effect on the food materials.

[0016] In some technical solutions, optionally, at least one reflection fin extends along a second direction, and the second direction is different from the first direction.

[0017] In this technical solution, at least one reflective fin extends in the second direction, and the second direction is different from the first direction. That is to say, the extending direction of at least one reflective fin is different from the direction in which the microwave flows out of the first microwave channel, so that the microwave can be reflected multiple times to excite a uniform electromagnetic field, thereby improving the uniformity of food cooking. Moreover, compared with the problems of rotating the food to be cooked or disturbing the microwave by the antenna in the related technology to improve the uniformity of microwave cooking, there is no need to set up a stirring motor and a motor bracket, which can improve the volume ratio of the product and also reduce the stretching height of the bottom plate of the appliance body, further reducing the production cost of the cooking appliance.

[0018] Optionally, the second direction is the height direction of the appliance body.

[0019] In some technical solutions, optionally, the waveguide assembly further includes a fixing plate, and the fixing plate is connected to a plurality of reflective fins.

[0020] In this technical solution, it is defined that the waveguide assembly further includes a fixing plate. Specifically, the fixing plate is connected to a plurality of reflective fins, so as to improve the installation reliability of the plurality of reflective fins. In addition, the plurality of reflective fins are fixed in the installation cavity through the fixing plate, which is beneficial to reducing the installation difficulty of the plurality of reflective fins and improving the assembly efficiency of the cooking appliance.

[0021] In some technical solutions, optionally, the appliance body is further provided with a feeding port, and the feeding port is located between the installation cavity and the cooking cavity and is communicated with the installation cavity.

[0022] In this technical solution, it is defined that the appliance body is further provided with a feeding port. Specifically, the feeding port is located between the installation cavity and the cooking cavity. That is to say, the microwave generated by the magnetron is fed into the cooking cavity after passing through the first microwave channel, the installation cavity and the feeding port in sequence. Since a plurality of reflective fins are provided at the installation cavity, the microwave can be reflected multiple times to excite a traveling wave. And by setting the feeding port between the installation cavity and the cooking cavity, that is, setting the feeding port in the area close to the waveguide tail wing, the secondary excitation of the traveling wave can be realized, achieving the effect of changing the advancing trajectory of the traveling wave, thereby improving the uniformity of food cooking and ensuring the cooking effect of the food.

[0023] In some technical solutions, optionally, the appliance body is further provided with a reflective edge, and the reflective edge is provided at the feeding port and is located on the side of the installation cavity away from the first microwave channel.

[0024] In this technical solution, it is defined that the appliance body is further provided with a reflective edge. Specifically, the reflective edge is provided at the feeding port, and the reflective edge is located on the side of the installation cavity away from the first microwave channel. That is to say, the reflective edge is provided in the area close to the waveguide tail wing. By designing the width of the reflective edge, the size of the feeding port can be adjusted, so as to realize the secondary excitation of the traveling wave, achieve the effect of changing the advancing trajectory of the traveling wave, thereby improving the uniformity of food cooking and ensuring the cooking effect of the food.

[0025] Optionally, the appliance body further includes a U-shaped plate which forms part of the cavity wall of the cooking cavity, and both the feed port and the reflection edge are provided on the U-shaped plate. Optionally, the reflection edge and the U-shaped plate are of an integral structure. Since multiple reflection fins are integrated in the waveguide assembly, compared with integrating the reflection fins on the U-shaped plate or the top plate, the front and rear baffle parts and the associated welding costs and deformation problems can be eliminated.

[0026] In some technical solutions, optionally, the cooking appliance further includes a wave-transmitting plate which is disposed in the cooking cavity and on the side of the feed port facing away from the installation cavity, and the wave-transmitting plate seals the feed port.

[0027] In this technical solution, it is defined that the cooking appliance further includes a wave-transmitting plate. Specifically, the wave-transmitting plate is arranged in the cooking cavity. Optionally, the cooking appliance further includes a grill which is placed on the wave-transmitting plate and can support the grill. In addition, the food ingredients can also be placed on the wave-transmitting plate.

[0028] It can be understood that the wave-transmitting plate can transmit microwaves. That is to say, the microwaves generated by the magnetron can penetrate the wave-transmitting plate and be fed into the cooking cavity after passing through the first microwave channel, the installation cavity and the feed port in sequence, so as to realize cooking the food ingredients in the cooking cavity with microwaves. In addition, since the wave-transmitting plate seals the feed port, it can prevent food residues in the cooking cavity from falling into the installation cavity through the feed port.

[0029] Optionally, the wave-transmitting plate includes a plastic plate or a glass plate.

[0030] In some technical solutions, optionally, an opening is provided on the side of the installation cavity facing the cooking cavity, and the opening is disposed opposite to and communicated with the feed port.

[0031] In this technical solution, it is defined that an opening is provided on the side of the installation cavity facing the cooking cavity. Specifically, the opening is opposite to and communicated with the feed port. That is to say, the microwaves generated by the magnetron are fed into the cooking cavity after passing through the first microwave channel, the installation cavity, the opening and the feed port in sequence, so as to cook the food ingredients in the cooking cavity.

[0032] By providing the opening and the feed port in the area close to the waveguide fin, the secondary excitation of the traveling wave can be realized, achieving the effect of changing the advancing trajectory of the traveling wave, thereby improving the uniformity of food ingredient cooking and ensuring the cooking effect of the food ingredients.

[0033] In some technical solutions, optionally, the waveguide assembly includes a first waveguide part and a second waveguide part. Among them, at least a part of the first waveguide part is disposed on the side of the appliance body, the magnetron is disposed in the first waveguide part, the first waveguide part is provided with a first microwave channel, the second waveguide part is connected to the first waveguide part and is disposed at the bottom of the appliance body, and the second waveguide part is provided with an installation cavity.

[0034] In this technical solution, it is defined that the waveguide assembly includes a first waveguide part and a second waveguide part. Specifically, at least part of the first waveguide part is arranged on the side of the appliance body, and the second waveguide part is arranged at the bottom of the appliance body, and the second waveguide part is provided with an installation cavity. That is to say, the microwave is fed into from the bottom of the cooking cavity. Therefore, compared with the related technology where the microwave is fed into from the top of the cooking cavity, a heating component can be arranged at the top of the cooking cavity to realize the baking function of the cooking appliance, solving the problem that the top of the microwave oven in the related technology cannot be compatible with an external barbecue module or an air fryer hot air module.

[0035] Since the first waveguide part and the second waveguide part are connected, that is to say, the waveguide assembly is of an L-shaped structure. The magnetron is arranged on the first waveguide part, that is to say, the magnetron is located on the side of the appliance body, thereby realizing the side layout of the electric control components of the cooking appliance, which is beneficial to realizing the compatibility of the transformer and the frequency converter and improving the manufacturability of the cooking appliance.

[0036] In some technical solutions, optionally, the waveguide assembly further includes a second microwave channel. The second microwave channel is arranged in the second waveguide part and is located between the installation cavity and the first microwave channel. The first microwave channel is communicated with the installation cavity through the second microwave channel; wherein, along the direction from the first microwave channel to the installation cavity, the width of the second microwave channel gradually increases.

[0037] In this technical solution, it is defined that the waveguide assembly further includes a second microwave channel. Specifically, the second microwave channel is located between the first microwave channel and the installation cavity. That is to say, the microwave generated by the magnetron is fed into the cooking cavity through the first microwave channel, the second microwave channel and the installation cavity in sequence.

[0038] Along the direction from the first microwave channel to the installation cavity, the width of the second microwave channel gradually increases. That is to say, the second microwave channel is a horn-shaped channel, and the width of the side close to the installation cavity is wider. Thus, when the microwave enters the installation cavity from the first microwave channel through the second microwave channel, the radiation range of the microwave can be increased, and then the reflection range of the microwave in the installation cavity can be increased, avoiding the microwave focusing on the middle area in the installation cavity, which is beneficial to improving the uniformity of the microwave and further improving the uniformity of the food cooking.

[0039] In some technical solutions, optionally, the width of the second microwave channel is smaller than the width of the installation cavity.

[0040] In this technical solution, it can be understood that if the width of the installation cavity is less than or equal to the width of the second microwave channel, the installation area of the reflection fins in the installation cavity is reduced, and the adjustable range is reduced, resulting in poor adjustability of the microwave.

[0041] By increasing the width of the installation cavity, the installation area of the reflection fins in the installation cavity can be increased, so that the adjustable range of the reflection fins is increased, and thus the adjustability of the microwave can be improved.

[0042] In some technical solutions, optionally, the first waveguide part and the second waveguide part are of an integral structure.

[0043] In this technical solution, since the first waveguide part and the second waveguide part are of an integral structure, the problems of water accumulation, water leakage and rust in the welding seam of the cooking cavity can be reduced. In addition, the integral structure is also beneficial to the processing and manufacturing of the waveguide component, and is beneficial to further reducing the production cost of the cooking appliance.

[0044] In some technical solutions, optionally, the first waveguide part includes a main body and a waveguide cover. Among them, the magnetron is arranged in the main body, and the waveguide cover is arranged on the side of the main body close to the cooking cavity and encloses a first microwave channel with the main body.

[0045] In this technical solution, it is defined that the first waveguide part includes a main body and a waveguide cover. Specifically, the waveguide cover is arranged on the main body, and the waveguide cover and the main body enclose a first microwave channel. By setting the waveguide cover, the sealing performance of the first microwave channel can be improved, microwave leakage can be avoided, and the reliability of the cooking appliance can be improved.

[0046] Optionally, the first waveguide part and the outer wall of the U-shaped plate enclose a first microwave channel.

[0047] In some technical solutions, optionally, the cooking appliance further includes an electric control component, and at least a part of the electric control component is arranged at the bottom of the magnetron.

[0048] In this technical solution, it is defined that the cooking appliance further includes an electric control component. Specifically, at least part of the electric control component is arranged at the bottom of the magnetron. Since the first waveguide part of the waveguide component is located on the side of the appliance body, and the magnetron is arranged on the first waveguide part, the side layout of the electrical components of the cooking appliance is realized, providing sufficient installation space for the electric control component, and improving the manufacturability and compatibility of the cooking appliance.

[0049] Optionally, the magnetron is horizontally arranged, that is, placed horizontally, so as to increase the installation space formed between the bottom of the magnetron and the inner wall of the electrical compartment, which is beneficial to the compatibility of the transformer and the frequency converter.

[0052] In this technical solution, it is defined that the cooking appliance also includes a heat dissipation component. Specifically, since the airflow generated by the heat dissipation component can flow to the magnetron and / or the electronic control component, the magnetron and / or the electronic control component can be cooled, thereby reducing the risk of failure of the magnetron and / or the electronic control component and improving the reliability and service life of the cooking appliance.

[0053] Optionally, a plurality of air inlet holes are provided on the back of the appliance body, and the electrical compartment is connected to the outside through the plurality of air inlet holes.

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0079] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0080] Next, refer to Figures 1 to 9 to describe the cooking appliance 100 provided according to some embodiments of the present invention.

[0081] In an embodiment according to the present application, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 shown, a cooking appliance 100 is proposed. The cooking appliance 100 includes: an appliance body 110, the appliance body 110 is provided with a cooking cavity 111; a waveguide assembly 120, which is arranged on the appliance body 110 and is located outside the cooking cavity 111. The waveguide assembly 120 includes an installation cavity 121, a plurality of reflecting fins 122 and a first microwave channel 126. The plurality of reflecting fins 122 are located in the installation cavity 121 and are arranged at intervals. One end of the first microwave channel 126 is communicated with the installation cavity 121; a magnetron 130 is arranged on the waveguide assembly 120. The other end of the first microwave channel 126 is communicated with the magnetron 130. The microwave generated by the magnetron 130 can be fed into the cooking cavity 111 through the first microwave channel 126 and the installation cavity 121 in sequence.

[0082] The cooking appliance 100 provided by an embodiment of the present invention includes an appliance body 110, a waveguide assembly 120, and a magnetron 130. Specifically, a cooking cavity 111 is provided in the appliance body 110. It can be understood that by placing food ingredients in the cooking cavity 111 and starting the cooking appliance 100, the food ingredients in the cooking cavity 111 can be cooked using microwaves.

[0083] The waveguide assembly 120 is disposed on the appliance body 110, and the magnetron 130 is disposed on the waveguide assembly 120. One end of the first microwave channel 126 communicates with the installation cavity 121, and the other end communicates with the magnetron 130. It can be understood that the magnetron 130 can generate microwaves, and the microwaves are fed into the cooking cavity 111 through the first microwave channel 126 and the installation cavity 121.

[0084] The waveguide assembly 120 includes a plurality of reflection fins 122, and the plurality of reflection fins 122 are spaced apart and disposed in the installation cavity 121. It can be understood that the reflection fins 122 can reflect microwaves. That is to say, before the microwaves are fed into the cooking cavity 111, the microwaves are multiply reflected by the plurality of reflection fins 122 to excite traveling waves, realizing the periodic crawling of the thermal field of the microwaves in the cooking cavity 111, exciting a uniform electromagnetic field, avoiding the thermal field being fixed in a specific area in the cooking cavity 111, which is beneficial to improving the uniformity of food ingredient cooking, and thus can improve the cooking effect of the food ingredients.

[0085] Moreover, by providing a plurality of reflection fins 122 in the installation cavity 121, the amplitude of the microwaves is increased after crawling through the plurality of reflection fins 122, so that the heating height of the microwaves on the food ingredients can be increased. At the same time, it can also play a guiding role for the microwaves.

[0086] In addition, since the plurality of reflection fins 122 are disposed in the installation cavity 121, that is to say, the plurality of reflection fins 122 are integrated in the waveguide assembly 120. Compared with integrating the plurality of reflection fins 122 in other areas of the cooking cavity 111, the integration of the microwave transmission and excitation system is improved, the number of components is reduced. At the same time, the waveguide and the reflection fin 122 are modularized, reducing the material requirements of the cooking cavity 111, thereby reducing the processing cost, welding cost, transportation cost of the components of the cooking appliance 100 and the deformation risk during transportation, and further reducing the production cost of the cooking appliance 100.

[0087] Optionally, the cooking appliance 100 includes a microwave oven, a microwave grill combination oven, or a microwave steam grill combination oven.

[0088] As Figure 2 shown, in some embodiments, optionally, at least two reflection fins 122 are spaced apart along a first direction, and the first direction includes the direction from the first microwave channel 126 to the installation cavity 121.

[0089] In this embodiment, since at least two reflection fins 122 are spaced along the direction from the first microwave channel 126 to the installation cavity 121, microwaves can crawl on the at least two reflection fins 122, thereby increasing the amplitude of the microwaves fed into the cooking cavity 111, and further enhancing the cooking effect on the food ingredients.

[0090] In addition, the microwaves generated by the magnetron 130 flow through the first microwave channel 126 to the installation cavity 121, and before being fed into the cooking cavity 111, they will flow through multiple reflection fins 122, thereby performing multiple reflections on the microwaves, exciting traveling waves, realizing the periodic crawling of the thermal field of the microwaves in the cooking cavity 111, exciting a uniform electromagnetic field, avoiding the thermal field being fixed in a specific area in the cooking cavity 111, being beneficial to improving the uniformity of food ingredient cooking, and further improving the cooking effect on the food ingredients.

[0091] As Figure 1 、 Figure 2 and Figure 6 shown, in some embodiments, optionally, at least one reflection fin 122 extends along a second direction, and the second direction is different from the first direction.

[0092] In this embodiment, at least one reflection fin 122 extends along the second direction, and the second direction is different from the first direction. That is to say, the extending direction of at least one reflection fin 122 is different from the direction in which the microwaves flow out of the first microwave channel 126, so that multiple reflections can be performed on the microwaves, exciting a uniform electromagnetic field, and further improving the uniformity of food ingredient cooking. Moreover, compared with the problems of rotating the food to be cooked or disturbing the microwaves through an antenna to improve the uniformity of microwave cooking in the related art, there is no need to provide a stirring motor and a motor bracket, which improves the volume ratio of the product, and can also reduce the stretching height of the bottom plate of the appliance body 110, further reducing the production cost of the cooking appliance 100.

[0093] Optionally, the second direction is the height direction of the appliance body 110.

[0094] As Figure 2 shown, in some embodiments, optionally, the waveguide assembly 120 further includes a fixing plate 150, and the fixing plate 150 is connected to multiple reflection fins 122.

[0095] In this embodiment, it is defined that the waveguide assembly 120 further includes a fixing plate 150. Specifically, the fixing plate 150 is connected to multiple reflection fins 122, thereby improving the installation reliability of the multiple reflection fins 122. In addition, the multiple reflection fins 122 are fixed in the installation cavity 121 through the fixing plate 150, which is beneficial to reducing the installation difficulty of the multiple reflection fins 122 and improving the assembly efficiency of the cooking appliance 100.

[0096] AsFigure 1 and Figure 4 As shown in Figure 4 , in some embodiments, optionally, the appliance body 110 is further provided with a feed inlet 112, and the feed inlet 112 is located between the installation cavity 121 and the cooking cavity 111 and communicates with the installation cavity 121.

[0097] In this embodiment, it is defined that the appliance body 110 is further provided with a feed inlet 112. Specifically, the feed inlet 112 is located between the installation cavity 121 and the cooking cavity 111. That is to say, the microwave generated by the magnetron 130 is fed into the cooking cavity 111 after passing through the first microwave channel 126, the installation cavity 121 and the feed inlet 112 in sequence. Since a plurality of reflection fins 122 are provided at the installation cavity 121, the microwave can be multiply reflected to excite a traveling wave. And by setting the feed inlet 112 between the installation cavity 121 and the cooking cavity 111, that is, setting the feed inlet 112 in the area close to the waveguide tail fin, the secondary excitation of the traveling wave can be realized, achieving the effect of changing the advancing trajectory of the traveling wave, thereby improving the uniformity of food cooking and ensuring the cooking effect of the food.

[0098] As Figure 1 and Figure 4 As shown in Figure 4 , in some embodiments, optionally, the appliance body 110 is further provided with a reflection edge 113, and the reflection edge 113 is provided at the feed inlet 112 and is located on the side of the installation cavity 121 away from the first microwave channel 126.

[0099] In this embodiment, it is defined that the appliance body 110 is further provided with a reflection edge 113. Specifically, the reflection edge 113 is provided at the feed inlet 112, and the reflection edge 113 is located on the side of the installation cavity 121 away from the first microwave channel 126. That is to say, the reflection edge 113 is set in the area close to the waveguide tail fin. By designing the width of the reflection edge 113, the size of the feed inlet 112 can be adjusted, thereby realizing the secondary excitation of the traveling wave, achieving the effect of changing the advancing trajectory of the traveling wave, and further improving the uniformity of food cooking and ensuring the cooking effect of the food.

[0100] Optionally, the appliance body 110 further includes a U-shaped plate, and the U-shaped plate forms a part of the cavity wall of the cooking cavity 111, and both the feed inlet 112 and the reflection edge 113 are provided on the U-shaped plate. Optionally, the reflection edge 113 and the U-shaped plate are of an integral structure. Since a plurality of reflection fins 122 are integrated in the waveguide component 120, compared with integrating the reflection fins 122 on the U-shaped plate or the top plate, the front and rear baffle parts and the welding cost and deformation problems brought by them can be removed.

[0101] As Figure 1 and Figure 3As shown, in some embodiments, optionally, the cooking appliance 100 further includes a wave-transmitting plate 160. The wave-transmitting plate 160 is disposed in the cooking cavity 111 and on the side of the feed inlet 112 facing away from the installation cavity 121. The wave-transmitting plate 160 covers the feed inlet 112.

[0102] In this embodiment, it is defined that the cooking appliance 100 further includes a wave-transmitting plate 160. Specifically, the wave-transmitting plate 160 is disposed in the cooking cavity 111. Optionally, the cooking appliance 100 further includes a grill. The grill is placed on the wave-transmitting plate 160, which can play a role in supporting the grill. In addition, food ingredients can also be placed on the wave-transmitting plate 160.

[0103] It can be understood that the wave-transmitting plate 160 can transmit microwaves. That is to say, after the microwaves generated by the magnetron 130 pass through the first microwave channel 126, the installation cavity 121, and the feed inlet 112 in sequence, they can penetrate the wave-transmitting plate 160 and be fed into the cooking cavity 111, so as to realize cooking the food ingredients in the cooking cavity 111 with microwaves. In addition, since the wave-transmitting plate 160 covers the feed inlet 112, food residues and the like in the cooking cavity 111 can be prevented from falling into the installation cavity 121 through the feed inlet 112.

[0104] Optionally, the wave-transmitting plate 160 includes a plastic plate or a glass plate.

[0105] As Figure 1 and Figure 2 shown, in some embodiments, optionally, an opening 230 is provided on the side of the installation cavity 121 facing the cooking cavity 111. The opening 230 is disposed opposite to and communicated with the feed inlet 112.

[0106] In this embodiment, it is defined that an opening 230 is provided on the side of the installation cavity 121 facing the cooking cavity 111. Specifically, the opening 230 is opposite to and communicated with the feed inlet 112. That is to say, after the microwaves generated by the magnetron 130 pass through the first microwave channel 126, the installation cavity 121, the opening 230, and the feed inlet 112 in sequence, they are fed into the cooking cavity 111 to cook the food ingredients in the cooking cavity 111.

[0107] By providing the opening 230 and the feed inlet 112 in the area close to the waveguide fin, secondary excitation of the traveling wave can be realized, achieving the effect of changing the advancing trajectory of the traveling wave, thereby improving the uniformity of food ingredient cooking and ensuring the cooking effect of the food ingredients.

[0108] As Figure 1 and Figure 2As shown, in some embodiments, optionally, the waveguide assembly 120 includes a first waveguide portion 123 and a second waveguide portion 124. Among them, at least a part of the first waveguide portion 123 is provided on the side of the appliance body 110, the magnetron 130 is provided on the first waveguide portion 123, the first waveguide portion 123 is provided with a first microwave channel 126, the second waveguide portion 124 is connected to the first waveguide portion 123 and is provided at the bottom of the appliance body 110, and the second waveguide portion 124 is provided with an installation cavity 121.

[0109] In this embodiment, it is defined that the waveguide assembly 120 includes a first waveguide portion 123 and a second waveguide portion 124. Specifically, at least a part of the first waveguide portion 123 is arranged on the side of the appliance body 110, the second waveguide portion 124 is arranged at the bottom of the appliance body 110, and the second waveguide portion 124 is provided with an installation cavity 121. That is to say, the microwave is fed into from the bottom of the cooking cavity 111. Thus, compared with the related technology where the microwave is fed into from the top of the cooking cavity, a heating component 210 can be arranged at the top of the cooking cavity 111 to realize the baking function of the cooking appliance 100, and the problem that the top of the microwave oven in the related technology cannot be compatible with an external barbecue module or an air fry hot air module is solved.

[0110] Since the first waveguide portion 123 and the second waveguide portion 124 are connected, that is to say, the waveguide assembly 120 is of an L-shaped structure. The magnetron 130 is arranged on the first waveguide portion 123, that is to say, the magnetron 130 is located on the side of the appliance body 110, thereby realizing the side layout of the electric control assembly 170 of the cooking appliance 100, which is beneficial to realizing the compatibility of the transformer 171 and the frequency converter and improving the manufacturability of the cooking appliance 100.

[0111] It can be understood that the second waveguide portion 124 and the outer wall of the U-shaped plate enclose to form the installation cavity 121.

[0112] As Figure 2 As shown, in some embodiments, optionally, the waveguide assembly 120 further includes a second microwave channel 127. The second microwave channel 127 is arranged in the second waveguide portion 124 and is located between the installation cavity 121 and the first microwave channel 126. The first microwave channel 126 is communicated with the installation cavity 121 through the second microwave channel 127; among them, along the direction from the first microwave channel 126 to the installation cavity 121, the width of the second microwave channel 127 gradually increases.

[0113] In this embodiment, it is defined that the waveguide assembly 120 further includes a second microwave channel 127. Specifically, the second microwave channel 127 is located between the first microwave channel 126 and the installation cavity 121. That is to say, the microwave generated by the magnetron 130 is fed into the cooking cavity 111 in sequence through the first microwave channel 126, the second microwave channel 127 and the installation cavity 121.

[0114] In the direction along the first microwave channel 126 to the installation cavity 121, the width of the second microwave channel 127 gradually increases. That is to say, the second microwave channel 127 is a horn-shaped channel, and the width of the side close to the installation cavity 121 is wider. Thus, when the microwave enters the installation cavity 121 from the first microwave channel 126 through the second microwave channel 127, the radiation range of the microwave can be increased, and then the reflection range of the microwave in the installation cavity 121 can be increased, avoiding the microwave focusing on the middle area in the installation cavity 121, which is beneficial to improving the uniformity of the microwave and further improving the uniformity of food cooking.

[0115] Optionally, the first microwave channel 126 includes a first channel and a second channel that are connected and communicate with each other. The first channel is located on the side of the cooking cavity 111, and the second channel is located at the bottom of the cooking cavity 111. Moreover, the second channel is located between the first channel and the second microwave channel 127. Among them, in the direction along the first microwave channel 126 to the installation cavity 121, the width of the end of the second channel close to the second microwave channel 127 gradually increases. That is to say, the end of the second channel close to the second microwave channel 127 is also horn-shaped.

[0116] As Figure 2 shown, in some embodiments, optionally, the width of the second microwave channel 127 is smaller than the width of the installation cavity 121.

[0117] In this embodiment, it can be understood that if the width of the installation cavity 121 is less than or equal to the width of the second microwave channel 127, the installation area of the reflection fin 122 in the installation cavity 121 will be reduced, and the adjustable range will be reduced, resulting in poor adjustability of the microwave.

[0118] By increasing the width of the installation cavity 121, the installation area of the reflection fin 122 in the installation cavity 121 can be increased, so that the adjustable range of the reflection fin 122 is increased, and then the adjustability of the microwave can be improved.

[0119] In some embodiments, optionally, the first waveguide part 123 and the second waveguide part 124 are of an integral structure.

[0120] In this embodiment, since the first waveguide part 123 and the second waveguide part 124 are of an integral structure, the problems of water accumulation, water leakage and rusting at the welding seam of the cooking cavity 111 can be reduced. In addition, the integral structure is also beneficial to the processing and manufacturing of the waveguide component 120, and is beneficial to further reducing the production cost of the cooking appliance 100.

[0121] As Figure 1 and Figure 2As shown, in some embodiments, optionally, the first waveguide part 123 includes a body 220 and a waveguide cover 125. Among them, the magnetron 130 is disposed in the body 220, and the waveguide cover 125 is disposed on one side of the body 220 close to the cooking cavity 111 and encloses with the body 220 to form a first microwave channel 126.

[0122] In this embodiment, it is defined that the first waveguide part 123 includes a body 220 and a waveguide cover 125. Specifically, the waveguide cover 125 is disposed on the body 220, and the waveguide cover 125 and the body 220 enclose to form a first microwave channel 126. By providing the waveguide cover 125, the sealing performance of the first microwave channel 126 can be improved, microwave leakage can be avoided, and the reliability of the cooking appliance 100 can be enhanced.

[0123] Optionally, the first waveguide part 123 and the outer wall of the U-shaped plate enclose to form a first microwave channel 126.

[0124] As Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments, optionally, the cooking appliance 100 further includes an electric control component 170, and at least a part of the electric control component 170 is disposed at the bottom of the magnetron 130.

[0125] In this embodiment, it is defined that the cooking appliance 100 further includes an electric control component 170. Specifically, at least part of the electric control component 170 is disposed at the bottom of the magnetron 130. Since the first waveguide part 123 of the waveguide component 120 is located at the side of the appliance body 110 and the magnetron 130 is disposed on the first waveguide part 123, a side layout of the electrical components of the cooking appliance 100 is realized, sufficient installation space is provided for the electric control component 170, and the manufacturability and compatibility of the cooking appliance 100 are improved.

[0126] Optionally, the magnetron 130 is horizontally arranged, that is, placed horizontally, so as to increase the installation space formed between the bottom of the magnetron 130 and the inner wall of the electrical appliance compartment 114, which is beneficial to realizing the compatibility of the transformer 171 and the frequency converter.

[0127] Optionally, the electric control component 170 is a frequency converter, or the electric control component 170 includes a transformer 171 and a capacitor 172.

[0128] As Figure 3 , Figure 5 and Figure 6As shown, in some embodiments, optionally, the appliance body 110 is further provided with an electrical appliance chamber 114. The electrical appliance chamber 114 communicates with the outside. The magnetron 130 and the electronic control assembly 170 are located in the electrical appliance chamber 114. The cooking appliance 100 further includes a heat dissipation assembly 180. The heat dissipation assembly 180 is disposed in the electrical appliance chamber 114, and the airflow generated by the heat dissipation assembly 180 can flow to at least one of the magnetron 130 and the electronic control assembly 170.

[0129] In this embodiment, it is defined that the cooking appliance 100 further includes a heat dissipation assembly 180. Specifically, since the airflow generated by the heat dissipation assembly 180 can flow to the magnetron 130 and / or the electronic control assembly 170, the magnetron 130 and / or the electronic control assembly 170 can be cooled, the risk of failure of the magnetron 130 and / or the electronic control assembly 170 can be reduced, and the reliability and service life of the cooking appliance 100 can be improved.

[0130] Optionally, a plurality of air inlet holes are provided on the back of the appliance body 110, and the electrical appliance chamber 114 communicates with the outside through the plurality of air inlet holes.

[0131] Optionally, the heat dissipation assembly 180 includes a fan blade, a motor, and a bracket. The motor is disposed on the bracket, the fan blade is rotatably disposed on the bracket, and the fan blade is connected to the motor.

[0132] As Figure 3 、 Figure 5 and Figure 6 As shown, in some embodiments, optionally, the electronic control assembly 170 includes a transformer 171 and a capacitor 172. Among them, at least a part of the transformer 171 is disposed at the bottom of the magnetron 130, and at least a part of the capacitor 172 is disposed at the bottom of the heat dissipation assembly 180.

[0133] In this embodiment, it is defined that the electronic control assembly 170 includes a transformer 171 and a capacitor 172. Specifically, since the first waveguide portion 123 of the waveguide assembly 120 is located on the side of the appliance body 110 and the magnetron 130 is disposed on the first waveguide portion 123, the side layout of the electrical components of the cooking appliance 100 is realized, sufficient installation space is provided for the transformer 171 and the capacitor 172. The transformer 171 is disposed below the magnetron 130, and the capacitor 172 is disposed below the heat dissipation assembly 180. While realizing the reliable installation of the electronic control assembly 170, compared with the frequency converter, the production cost of the cooking appliance 100 can be reduced.

[0134] Optionally, the capacitor 172 includes a high-voltage capacitor.

[0135] As Figure 3 、 Figure 5 and Figure 6As shown, in some embodiments, optionally, the cooking appliance 100 further includes a filter board 190, which is disposed on the heat dissipation assembly 180 and is located on the side of the heat dissipation assembly 180 away from the variable capacitor 172.

[0136] In this embodiment, it is defined that the cooking appliance 100 further includes a filter board 190. Specifically, the filter board 190 is disposed on the heat dissipation assembly 180, and the filter board 190 is located on the side of the heat dissipation assembly 180 away from the variable capacitor 172. That is to say, the filter board 190 is located on the top of the heat dissipation assembly 180, so as to realize a reasonable layout of the electrical components of the cooking appliance 100.

[0137] As Figure 1 、 Figure 3 、 Figure 5 and Figure 7 As shown, in some embodiments, optionally, the cooking appliance 100 further includes a heating assembly 210, which is disposed on the appliance body 110. Along the second direction, the heating assembly 210 and the installation cavity 121 are respectively located on both sides of the cooking cavity 111 for heating the cooking cavity 111.

[0138] In this embodiment, it is defined that the cooking appliance 100 further includes a heating assembly 210. Specifically, the heating assembly 210 can heat the cooking cavity 111, so as to realize the baking function of the cooking appliance 100, that is, the cooking appliance 100 is a microwave and baking integrated machine or a microwave, steaming and baking integrated machine.

[0139] Along the second direction, the heating assembly 210 and the installation cavity 121 are respectively located on both sides of the cooking cavity 111. Optionally, the heating assembly 210 is located on the top of the cooking cavity 111, and the installation cavity 121 is located on the bottom of the cooking cavity 111, so as to improve the cooking efficiency and be beneficial to improving the uniformity of the heat received by the food during cooking, and further improve the cooking effect of the food.

[0140] Optionally, the heating assembly 210 includes a heating tube assembly or a hot air assembly.

[0141] Optionally, the heating tube assembly is an internal heating tube or an external heating tube.

[0142] Basically, microwave ovens in the related art all use a standing wave field to heat food relying on hot spots. The standing wave cold and hot spots are fixed, resulting in difficult cooking uniformity. Although, the problem of poor uniformity of microwave cooking can be improved to a certain extent by rotating the food to be heated or disturbing the microwave energy by an antenna. However, the improvement space is limited, the debugging period of cooking uniformity is long, and different foods lead to inconsistent microwave field distribution and inconsistent cold and hot fields inside the cavity, and it is difficult to ensure the effectiveness of uniformity on all foods.

[0143] In addition, in the traveling-wave microwave products in the related art, there are problems such as poor product compatibility and low manufacturability. The present invention aims to provide a new generation of traveling-wave microwave ovens (cooking appliance 100) with high compatibility, good manufacturability, and uniform microwave cooking.

[0144] As Figure 3 and Figure 5 shown, the top of the present invention can be compatible with an external heating tube assembly or an air fryer hot air assembly (heating assembly 210). The right side is a centralized electrical appliance compartment 114, and the rear side of the electrical appliance compartment 114 is a fan assembly (heat dissipation assembly 180). The fan assembly (heat dissipation assembly 180) integrates a motor, a fan bracket, fan blades, and a filter board 190. The axial fan sucks in cold air from the outside through the opening (air inlet hole) of the rear plate and blows it into the electrical appliance compartment 114 to dissipate heat from each electrical component (electrical control component 170 and magnetron 130). The L-shaped waveguide (waveguide component 120) is welded to the right side (side part) and the bottom outer wall of the cavity (cooking cavity 111) to achieve bottom-feed microwave feeding, and the magnetron 130 is horizontally arranged in the electrical appliance compartment 114. For the transformer board platform solution, it can be compatible with the conventional layout, that is, the transformer 171 is placed below the magnetron 130, and the high-voltage capacitor (capacitor 172) is placed below the fan assembly (heat dissipation assembly 180).

[0145] As Figure 1 shown, the bottom feed inlet 112 of the cavity (cooking cavity 111) realizes the feeding of microwaves into the cavity. The fins (reflective fins 122) inside the waveguide (waveguide component 120) convert the standing wave into a traveling wave based on the principle of multiple reflections. The left feed inlet side (reflective side 113) of the U-plate (U-shaped plate) is adjusted left and right to achieve secondary excitation of the traveling wave, changing the forward trajectory of the traveling wave in the cavity, which can further improve the uniformity of microwaves in the cavity.

[0146] Figure 2 Shows the waveguide component solution for exciting the traveling wave. The waveguide (waveguide component 120) adopts an overall L-shaped layout. A magnetron bracket is welded on the right side to fix the magnetron 130, and fins (reflective fins 122) are welded at the bottom for exciting the traveling wave. The first waveguide cover (body 220) and the second waveguide cover (waveguide cover 125) are combined to form a waveguide transmission closed channel (first microwave channel 126). Among them, the second waveguide cover (waveguide cover 125) is a non-essential component, and the first waveguide cover (first waveguide part 123) can be profiled with the cavity (cooking cavity 111) and sealed with the outer wall of the U-plate (U-shaped plate) to form a microwave transmission channel (first microwave channel 126). The combination solution of the transformer 171 and the high-voltage capacitor (capacitor 172) is replaced with an inverter (i.e., without a high-voltage capacitor, and the transformer 171 is replaced with an inverter), which solves the problem that it cannot be compatible with the transformer 171 (the transformer version has a cost advantage).
