Description
Technical Field
[0001] This invention relates to the field of household appliance technology, and more specifically, to a cooking appliance. Background Technology
[0002] In related technologies, microwave ovens use a rotating stirrer to disperse the microwaves generated by the magnetron before feeding them into the cooking cavity. However, the rotating stirrer has a complex structure, high cost, and occupies a significant amount of space within the microwave oven, thus impacting the product's market competitiveness. Summary of the Invention
[0003] The present invention aims to solve at least one of the technical problems existing in the prior art.
[0004] Therefore, the present invention provides a cooking utensil.
[0005] The present invention provides a cooking appliance, comprising: a housing having a cooking cavity inside the housing; a microwave assembly having a microwave outlet connected to the cooking cavity; and an antenna device including a plate covering the microwave outlet of the microwave assembly, the plate having multiple slits through which microwaves generated by the microwave assembly pass into the cooking cavity.
[0006] The cooking appliance provided by the present invention includes a housing with a cooking cavity for holding ingredients to be cooked. Specifically, the cooking cavity may be provided with a holding part, in which the ingredients can be placed before cooking, and then the holding part is placed in the cooking cavity for cooking.
[0007] Furthermore, the cooking appliance also includes a microwave unit, which generates microwaves and then delivers these microwaves into the cooking cavity to microwave heat the food inside. Specifically, the cooking appliance's housing may have a through-hole connected to the cooking cavity. Correspondingly, the microwave outlet of the microwave unit is connected to the through-hole on the housing, meaning the microwave outlet of the microwave unit is connected to the cooking cavity. This allows the microwaves generated by the microwave unit to be delivered into the cooking cavity through the through-hole, thereby achieving microwave heating of the food inside the cooking cavity.
[0008] Furthermore, the cooking appliance may also include an antenna device. By setting the antenna device, the microwaves generated by the microwave component can be guided during the conduction process, so that the microwaves entering the cooking cavity can generate a uniform heat field in the cooking cavity, thereby ensuring the uniformity of microwave heating of the food in the cooking cavity, that is, ensuring the heating effect of the microwave.
[0009] Specifically, the antenna device may include a plate with multiple slits. The plate is then placed over the microwave outlet of the microwave assembly, so that the microwaves emitted from the microwave outlet can be refracted through the multiple slits on the plate and thus form multiple uniformly distributed microwaves after entering the cooking cavity, thereby generating a uniform heat field within the cooking cavity.
[0010] It is understandable that the microwaves generated by the microwave component are emitted from the microwave outlet to form a large electromagnetic wave. The energy is concentrated in the central part of the electromagnetic wave. After interference from multiple gaps on the plate, the large electromagnetic wave forms smaller electromagnetic waves at each gap behind the plate. In other words, the large electromagnetic wave is dispersed into multiple smaller electromagnetic waves, thereby dispersing the microwave energy along the arrangement of multiple gaps. This can create a more uniform heat field in the cooking cavity, thereby improving the uniformity of microwave heating.
[0011] By configuring the antenna device as a plate and creating multiple slits on the plate, microwaves passing through the antenna device can form a uniform heat field within the cooking cavity, ensuring uniform heating of the food inside. Compared to related technologies where the antenna is configured as a rotating stirring blade, the antenna device of this application eliminates the need for a drive mechanism to rotate the stirring blade, reducing the space occupied by the antenna in the cooking appliance, lowering manufacturing costs, and enhancing market competitiveness.
[0012] Specifically, the through holes on the cabinet can be made on the bottom wall of the cabinet, and the microwave unit is set at the bottom of the cabinet. In this way, microwaves can be delivered from the bottom wall of the cabinet into the cooking cavity. When the microwaves come into contact with the food, they can form hot spots on the bottom of the food, ensuring the microwave heating effect of the food.
[0013] The cooking appliance provided by this invention includes a housing and a microwave assembly. The housing includes a cooking cavity, and the microwave outlet of the microwave assembly is opposite to the cooking cavity to ensure that the microwaves generated by the microwave assembly can enter the cooking cavity to microwave heat the food inside. Furthermore, the cooking appliance also includes an antenna device, which includes a plate and multiple slits formed in the plate. By covering the microwave outlet of the microwave assembly with the plate, the microwaves emitted from the microwave outlet are dispersed by the interference of the multiple slits, thereby generating hot spots at each slit after entering the cooking cavity. This results in a more uniform distribution of hot spots within the cooking cavity, ensuring uniform heating of the food inside. Compared to antennas with rotating stirring blades, this invention eliminates the need for a driving device to drive the stirring blade, simplifying the antenna structure, reducing the space occupied by the antenna, and simultaneously reducing the manufacturing cost of the cooking appliance, thus improving its market competitiveness.
[0014] In addition, the cooking utensil according to the above-described technical solution provided by the present invention may also have the following additional technical features:
[0015] In the above technical solution, the gap further includes an elongated hole opened on the plate body, the gap extends along the first direction and is opened on the plate body, and multiple gaps are arranged at intervals along the second direction on the plate body, wherein the first direction is perpendicular to the second direction.
[0016] In this technical solution, the gap may include an elongated hole formed on the plate. Further, the gap on the plate may be configured to extend along a first direction of the plate, while multiple gaps may be spaced apart along a second direction of the plate. The first direction and the second direction are perpendicular to each other. That is, multiple gaps on the plate are arranged parallel to each other, and are spaced apart along the second direction, while the extension direction of the gaps is perpendicular to the arrangement direction of the multiple gaps.
[0017] Furthermore, the distance between two adjacent gaps can be set to be equal, that is, multiple gaps are evenly distributed on the plate along the second direction. In this way, the microwaves generated by the microwave component enter the cooking cavity after passing through the interference of multiple gaps, forming hot spots at the location of each gap. This means that multiple hot spots can be evenly distributed in the cooking cavity, thereby further ensuring the uniformity of heating of the food in the cooking cavity by the cooking appliance.
[0018] In any of the above technical solutions, further, along the second direction, the width of the gap is 0.07λ to 0.08λ, where λ is the wavelength of the microwave emitted by the microwave component.
[0019] In this technical solution, along the second direction, that is, along the direction in which the multiple slits are arranged, the width of the slits can be set to 0.07λ to 0.08λ. Here, λ represents the wavelength of the microwaves emitted by the microwave component of the cooking appliance.
[0020] Specifically, taking a microwave oven as an example, the wavelength of the microwaves emitted by the microwave component of a microwave oven is typically 192 mm. Correspondingly, the width of the gap on the antenna device's plate can be set from 0.07×192 mm to 0.08×192 mm, which is 13.44 mm to 15.36 mm. In practical applications, the width of the gap can be set to 15 mm.
[0021] By adjusting the width of the gaps on the plate, it can be ensured that the microwaves generated by the microwave unit can form a uniform and sufficiently strong heat field in the cooking cavity after passing through the gaps, thus ensuring the heating effect on the food in the cooking cavity.
[0022] In any of the above technical solutions, further, along the second direction, the distance between the center lines of two adjacent gaps is 0.2λ to 0.3λ, where λ is the wavelength of the microwave emitted by the microwave component.
[0023] In this technical solution, along the second direction, that is, along the arrangement direction of the multiple slits, the distance between two adjacent slits can be set to 0.2λ to 0.3λ, where λ represents the wavelength of the microwaves emitted by the microwave component of the cooking appliance.
[0024] Specifically, taking a microwave oven as an example, the wavelength of the microwaves emitted by the microwave unit of a microwave oven is typically 192 mm. Correspondingly, the distance between two adjacent gaps can be set from 0.2 × 192 mm to 0.3 × 192 mm, or 38.4 mm to 57.6 mm. In practical applications, the width of the gap can be set to 48 mm.
[0025] By adjusting the width of the gaps on the plate, the interference between microwaves generated by the microwave unit after passing through two adjacent gaps can be avoided, thus ensuring the heating effect on the food inside the cooking cavity.
[0026] In any of the above technical solutions, the plate further includes: a frame; multiple partitions, the two ends of which are connected to the opposite sides of the frame, the multiple partitions are arranged at intervals along the second direction, and gaps are formed between adjacent partitions.
[0027] In this technical solution, the plate body may include a frame and multiple partitions located within the frame. Specifically, the two ends of the multiple partitions are connected to opposite sides of the frame, and the length direction of the partitions is a first direction. The multiple partitions can be arranged in parallel and spaced apart along a second direction. In this way, the arrangement of multiple partitions allows gaps to be formed between adjacent partitions, enabling the refraction of microwaves generated by the microwave components, thereby generating a uniform heat field within the cooking cavity.
[0028] Accordingly, the distance between the edges of two adjacent partitions can be set to 0.07λ to 0.08λ. At the same time, by setting the width of the partitions, the distance between the center lines of the gaps formed between two adjacent partitions is kept at 0.2λ to 0.3λ to ensure the uniformity of the heat field distribution in the cooking cavity.
[0029] In any of the above technical solutions, the partition plate is further provided with a plurality of recesses, which extend from both sides of the partition plate toward the center line of the partition plate, and the plurality of recesses are spaced apart along the first direction.
[0030] In this technical solution, multiple recesses can be provided on the partition. Specifically, multiple recesses are provided on both sides of the partition, and the multiple recesses are spaced apart along a first direction. That is, along the length of the gap between two adjacent partitions, hollow portions are formed at intervals along the edge of the gap, and hollow portions can be formed on both edges of each gap, so that the hollow portions are arranged in an array on the plate.
[0031] By creating recesses on both sides of the partition, an array of perforated sections is formed on the plate. This allows microwaves passing through the plate to form hot spots at the locations of the perforated sections, thereby ensuring a uniformly distributed heat field within the cooking cavity and guaranteeing the uniform heating of the food inside the cooking cavity.
[0032] In any of the above technical solutions, the depth of the recess is further 0.06λ to 0.07λ, where λ is the wavelength of the microwave emitted by the microwave component.
[0033] In this technical solution, the depth of the recess can be set to 0.06λ to 0.07λ. Specifically, the recess extends from both sides of the partition towards the centerline of the partition, while the partitions are spaced apart along a second direction. That is, in the second direction, the depth of the recess is 0.06λ to 0.07λ.
[0034] Specifically, taking a microwave oven as an example, the wavelength of the microwaves emitted by the microwave component of a microwave oven is typically 192 mm. Correspondingly, the depth of the recess is 0.06 × 192 mm to 0.07 × 192 mm, or 11.52 mm to 13.44 mm. In practical applications, the width of the recess can be set to 12.5 mm.
[0035] By adjusting the depth of the recesses, the size of the array of perforated sections on the plate can be ensured, thereby guaranteeing the intensity of the microwaves passing through the perforations and the intensity of the heat field formed by the microwaves within the cooking cavity, thus ensuring the effective microwave heating of the food. Specifically, with a recess width of 12.5mm and a gap width of 15mm, the width of the perforated sections on the plate is 40mm.
[0036] In any of the above technical solutions, further, along the first direction, the width of the recess is 0.07λ to 0.08λ, where λ is the wavelength of the microwave emitted by the microwave component.
[0037] In this technical solution, the width of the recess along the first direction, that is, along the length of the gap, can be set to 0.07λ to 0.08λ. Here, λ represents the wavelength of the microwaves emitted by the microwave component of the cooking appliance.
[0038] Specifically, taking a microwave oven as an example, the wavelength of the microwaves emitted by the microwave unit of a microwave oven is typically 192 mm. Correspondingly, the distance between two adjacent gaps can be set from 0.07×192 mm to 0.08×192 mm, which is 13.44 mm to 15.36 mm. In practical applications, the width of the gap can be set to 15 mm.
[0039] By setting the width of the recess in the first direction, the size of the array of hollowed-out parts on the plate can be guaranteed, thereby ensuring the intensity of the microwaves passing through the hollowed-out parts, and thus ensuring the intensity of the heat field formed by the microwaves in the cooking cavity, which in turn ensures the microwave heating effect on the food.
[0040] In any of the above technical solutions, further, along the first direction, the distance between two adjacent recesses is 0.15λ to 0.2λ, where λ is the wavelength of the microwave emitted by the microwave component.
[0041] In this technical solution, along the first direction, that is, along the length of the gap, the distance between two adjacent recesses can be set to 0.15λ to 0.2λ. Here, λ represents the wavelength of the microwaves emitted by the microwave component of the cooking appliance.
[0042] Specifically, taking a microwave oven as an example, the wavelength of the microwaves emitted by the microwave component of a microwave oven is typically 192 mm. Correspondingly, the distance between two adjacent recesses can be set from 0.15 × 192 mm to 0.2 × 192 mm, or 28.8 mm to 38.4 mm. In practical applications, the width of the gap can be set to 36 mm.
[0043] By setting the distance between two adjacent recesses, the microwave wavelength can be matched to ensure the rational arrangement of multiple hollow parts on the plate, thereby ensuring the uniformity and intensity of the heat field distribution in the cooking cavity and ensuring the effect of microwave heating.
[0044] In any of the above technical solutions, a microwave inlet is further provided on one side of the enclosure, and the microwave component includes: a magnetron, which is used to generate microwaves; a waveguide, the inlet of which is connected to the magnetron, the outlet of which is the microwave outlet, and the plate covers the outlet of the waveguide.
[0045] In this technical solution, the microwave component may specifically include a magnetron and a waveguide, wherein the magnetron is used to generate microwaves, and correspondingly, the waveguide is used for microwave conduction. Specifically, the inlet of the waveguide is connected to the magnetron so that the microwaves generated by the magnetron can enter the waveguide, and further, the outlet of the waveguide is the microwave outlet, through which the microwaves generated by the magnetron can be output.
[0046] Accordingly, a microwave inlet can be provided on the body of the cooking appliance. By connecting the microwave outlet of the waveguide to the microwave inlet on the body, microwaves can be input into the cooking cavity of the appliance to heat the food using microwaves.
[0047] In any of the above technical solutions, the cooking appliance further includes a microwave oven.

[0054] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0055] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.
[0056] The following reference Figure 1 and Figure 2 To describe cooking appliances provided according to some embodiments of the present invention.
[0057] This invention provides a cooking utensil 100, such as Figure 1 As shown, the appliance includes a housing 102, which has a cooking cavity 122 inside; it also includes a microwave assembly 104, whose microwave outlet 124 is connected to the cooking cavity 122; further, the cooking appliance 100 also includes an antenna device 106, which includes a plate 120 covering the microwave outlet 124 of the microwave assembly 104. The plate 120 has multiple slits 108, through which the microwaves generated by the microwave assembly 104 are input into the cooking cavity 122.
[0058] The cooking appliance 100 provided by the present invention includes a housing 102, which has a cooking cavity 122 for holding ingredients to be cooked. Specifically, the cooking cavity 122 may be provided with a holding part. Before cooking the ingredients, the ingredients can be placed in the holding part, and then the holding part is placed in the cooking cavity 122 for cooking.
[0059] Furthermore, the cooking appliance 100 also includes a microwave component 104, which generates microwaves. These microwaves are then transmitted to the cooking cavity 122 to microwave heat the food within the cavity. Specifically, the housing 102 of the cooking appliance 100 may have a through-hole connected to the cooking cavity 122. Correspondingly, the microwave outlet 124 of the microwave component 104 is connected to the through-hole on the housing 102, meaning the microwave outlet 124 of the microwave component 104 is connected to the cooking cavity 122. This allows the microwaves generated by the microwave component 104 to be transmitted to the cooking cavity 122 through the through-hole, thereby achieving microwave heating of the food within the cooking cavity 122.
[0060] Furthermore, the cooking appliance 100 may also include an antenna device 106. By setting the antenna device 106, the microwaves generated by the microwave component 104 can be guided during the conduction process, so that the microwaves entering the cooking cavity 122 can generate a uniform heat field in the cooking cavity 122, thereby ensuring the uniformity of microwave heating of the food in the cooking cavity 122, that is, ensuring the heating effect of the microwaves.
[0061] Specifically, the antenna device 106 may include a plate 120, and a plurality of slits 108 are provided on the plate 120. At the same time, the plate 120 covers the microwave outlet 124 of the microwave assembly 104, so that the microwaves emitted from the microwave outlet 124 can be refracted through the plurality of slits 108 on the plate, and then form a plurality of uniformly distributed microwaves after entering the cooking cavity 122, so as to generate a uniform heat field in the cooking cavity 122.
[0062] It is understandable that the microwaves generated by the microwave component 104 are emitted from the microwave outlet 124 to form a large electromagnetic wave. The energy is concentrated in the central part of the electromagnetic wave. After interference from multiple gaps 108 on the plate 120, the large electromagnetic wave forms smaller electromagnetic waves at each gap 108 behind the plate 120. In other words, the large electromagnetic wave is dispersed into multiple smaller electromagnetic waves, thereby dispersing the microwave energy along the arrangement direction of the multiple gaps 108. This can create a more uniform heat field in the cooking cavity 122, thereby improving the uniformity of microwave heating.
[0063] By configuring the antenna device 106 as a plate 120 and multiple slots 108 formed on the plate 120, microwaves passing through the antenna device 106 can form a uniform heat field within the cooking cavity 122, ensuring uniform heating of the food within the cooking cavity 122. Compared to related technologies where the antenna is configured as a rotating stirring blade, the antenna device 106 of this application does not require a drive mechanism to rotate the stirring blade, reducing the space occupied by the antenna in the cooking appliance 100, thereby reducing the manufacturing cost of the cooking appliance 100 and improving its market competitiveness.
[0064] Specifically, the through hole on the housing 102 can be opened on the bottom wall of the housing 102. At the same time, the microwave component 104 is located below the housing 102. In this way, microwaves can be delivered from the bottom wall of the housing 102 into the cooking cavity 122. When the microwaves come into contact with the food, they can form a hot spot on the bottom of the food, ensuring the microwave heating effect of the food.
[0065] The cooking appliance 100 provided by the present invention includes a housing 102 and a microwave assembly 104. The housing 102 includes a cooking cavity 122, and the microwave outlet 124 of the microwave assembly 104 is opposite to the cooking cavity 122 to ensure that the microwaves generated by the microwave assembly 104 can enter the cooking cavity 122 to microwave heat the food inside the cooking cavity 122. Furthermore, the cooking appliance 100 also includes an antenna device 106, which includes a plate 120 and multiple slits 108 formed on the plate 120. By covering the microwave outlet 124 of the microwave assembly 104 with the plate 120, the microwaves emitted from the microwave outlet 124 are dispersed by the interference of the multiple slits 108, thereby generating hot spots at each slit 108 after entering the cooking cavity 122. This results in a more uniform distribution of hot spots generated by the microwaves within the cooking cavity 122, thus ensuring uniform heating of the food inside the cooking cavity 122. Compared to antennas with rotating stirring blades, there is no need to set up a driving device to drive the stirring blades, which simplifies the antenna structure, reduces the space occupied by the antenna, reduces the manufacturing cost of the cooking appliance 100, and improves the market competitiveness of the cooking appliance 100.
[0066] In the above embodiments, further, as Figure 2 As shown, the slit 108 includes an elongated hole opened on the plate 120. The slit 108 extends along a first direction and is opened on the plate 120. A plurality of slits 108 are arranged at intervals along a second direction on the plate 120, wherein the first direction is perpendicular to the second direction.
[0067] In this embodiment, the slit 108 may include an elongated hole formed on the plate 120. Further, the slit 108 on the plate 120 may be configured to extend along a first direction of the plate 120, while multiple slits 108 may be spaced apart along a second direction of the plate 120. The first direction and the second direction are perpendicular to each other. That is, the multiple slits 108 on the plate 120 are arranged parallel to each other, and the multiple slits 108 are spaced apart along the second direction, while the extending direction of the slits 108 is perpendicular to the arrangement direction of the multiple slits 108.
[0068] Furthermore, the distance between two adjacent gaps 108 can be set to be equal, that is, multiple gaps 108 are evenly arranged on the plate 120 along the second direction. In this way, the microwaves generated by the microwave component 104 enter the cooking cavity 122 after passing through the interference of multiple gaps 108, forming hot spots at the location of each gap 108. That is, multiple hot spots can be evenly arranged in the cooking cavity 122, thereby further ensuring the uniformity of heating of the food in the cooking cavity 122 by the cooking appliance 100.
[0069] Furthermore, along the second direction, the width of the slit 108 is 0.07λ to 0.08λ, where λ is the wavelength of the microwave emitted by the microwave component 104.
[0070] Specifically, along the second direction, that is, along the arrangement direction of the plurality of slits 108, the width of the slits 108 can be set to 0.07λ to 0.08λ. Here, λ represents the wavelength of the microwaves emitted by the microwave component 104 of the cooking appliance 100.
[0071] Specifically, taking a microwave oven as an example, the wavelength of the microwaves emitted by the microwave component 104 of the microwave oven is typically 192 mm. Correspondingly, the width of the slot 108 on the plate 120 of the antenna device 106 can be set to 0.07 × 192 mm to 0.08 × 192 mm, that is, 13.44 mm to 15.36 mm. Specifically, in practical applications, the width of the slot 108 can be set to 15 mm.
[0072] By setting the width of the gap 108 on the plate 120, it can be ensured that the microwaves generated by the microwave component 104 can form a uniform and sufficiently strong heat field in the cooking cavity 122 after being interfered with by the gap 108, so as to ensure the heating effect on the food in the cooking cavity 122.
[0073] Furthermore, along the second direction, the distance between the center lines of two adjacent slits 108 is 0.2λ to 0.3λ, where λ is the wavelength of the microwave emitted by the microwave component 104.
[0074] Specifically, along the second direction, that is, along the arrangement direction of the plurality of slits 108, the distance between two adjacent slits 108 can be set to 0.2λ to 0.3λ, where λ represents the wavelength of the microwaves emitted by the microwave component 104 of the cooking appliance 100.
[0075] Specifically, taking a microwave oven as an example, the wavelength of the microwaves emitted by the microwave component 104 of the microwave oven is typically 192 mm. Correspondingly, the distance between two adjacent gaps 108 can be set from 0.2 × 192 mm to 0.3 × 192 mm, or 38.4 mm to 57.6 mm. Specifically, in practical applications, the width of the gap 108 can be set to 48 mm.
[0076] By setting the width of the gap 108 on the plate 120, the microwaves generated by the microwave component 104 can be prevented from interfering with each other inside the cooking cavity 122 after passing through two adjacent gaps 108, so as to ensure the heating effect of the food inside the cooking cavity 122.
[0077] In any of the above embodiments, such as Figure 2 As shown, the plate body 120 further includes a frame 110 and a plurality of partitions 112. The two ends of the partitions 112 are connected to the opposite sides of the frame 110. The plurality of partitions 112 are arranged at intervals along the second direction, and a gap 108 is formed between two adjacent partitions 112.
[0078] In this embodiment, the plate 120 may include a frame 110 and a plurality of partitions 112 located within the frame 110. Specifically, the two ends of the plurality of partitions 112 are respectively connected to the opposite sides of the frame 110. Simultaneously, the length direction of the partitions 112 is a first direction, and the plurality of partitions 112 can be arranged in parallel and spaced apart along a second direction. Thus, the arrangement of the plurality of partitions 112 allows a gap 108 for the antenna device 106 to be formed between adjacent partitions 112, thereby refracting the microwaves generated by the microwave component 104 and generating a uniform heat field within the cooking cavity 122.
[0079] Accordingly, the distance between the edges of two adjacent partitions 112 can be set to 0.07λ to 0.08λ. At the same time, by setting the width of the partitions 112, the distance between the center lines of the gaps 108 formed between two adjacent partitions 112 is kept at 0.2λ to 0.3λ to ensure the uniformity of the heat field distribution in the cooking cavity 122.
[0080] Furthermore, the partition 112 is provided with a plurality of recesses 114, which extend from both sides of the partition 112 toward the center line of the partition 112, and the plurality of recesses 114 are spaced apart along the first direction.
[0081] Specifically, the partition 112 may also have multiple recesses 114. Specifically, multiple recesses 114 are provided on both sides of the partition 112, and the multiple recesses 114 are spaced apart along the first direction. That is, along the length of the gap 108 between two adjacent partitions 112, hollow portions are formed at intervals on the edge of the gap 108, and hollow portions can be formed on both edges of each gap 108, so that the hollow portions are arranged in an array on the plate 120.
[0082] By creating recesses 114 on both sides of the partition 112, an array of perforated portions is formed on the plate 120. This allows microwaves passing through the plate 120 to form corresponding hot spots at the locations of the perforated portions, thereby ensuring a uniformly distributed heat field within the cooking cavity 122, which in turn ensures the uniform heating of the food within the cooking cavity 122.
[0083] Furthermore, the depth of the recess 114 is 0.06λ to 0.07λ, where λ is the wavelength of the microwave emitted by the microwave component 104.
[0084] Specifically, the depth of the recess 114 can be set to 0.06λ to 0.07λ. Specifically, the recess 114 extends from both sides of the partition 112 toward the centerline of the partition 112, while the partitions 112 are arranged at intervals along a second direction. That is, in the second direction, the depth of the recess 114 is 0.06λ to 0.07λ.
[0085] Specifically, taking a microwave oven as an example, the wavelength of the microwaves emitted by the microwave component 104 of the microwave oven is typically 192 mm. Correspondingly, the depth of the recess 114 is 0.06 × 192 mm to 0.07 × 192 mm, which is 11.52 mm to 13.44 mm. Specifically, in practical applications, the width of the recess 114 can be set to 12.5 mm.
[0086] By adjusting the depth of the recess 114, the size of the array of perforated portions formed on the plate 120 can be ensured, thereby guaranteeing the intensity of microwaves passing through the perforated portions and the intensity of the heat field formed by microwaves within the cooking cavity 122, thus ensuring the effective microwave heating of the food. Specifically, with the width of the recess 114 being 12.5 mm and the width of the gap 108 being 15 mm, the width of the perforated portions formed on the plate 120 is 40 mm.
[0087] Furthermore, along the first direction, the width of the recess 114 is 0.07λ to 0.08λ, where λ is the wavelength of the microwave emitted by the microwave component 104.
[0088] Specifically, along the first direction, that is, along the length of the slit 108, the width of the recess 114 can be set to 0.07λ to 0.08λ. Here, λ represents the wavelength of the microwaves emitted by the microwave component 104 of the cooking appliance 100.
[0089] Specifically, taking a microwave oven as an example, the wavelength of the microwaves emitted by the microwave component 104 of the microwave oven is typically 192 mm. Correspondingly, the distance between two adjacent gaps 108 can be set from 0.07 × 192 mm to 0.08 × 192 mm, which is 13.44 mm to 15.36 mm. Specifically, in practical applications, the width of the gap 108 can be set to 15 mm.
[0090] By setting the width of the recess 114 in the first direction, the size of the array of hollowed-out portions formed on the plate 120 can be guaranteed, thereby ensuring the intensity of microwaves passing through the hollowed-out portions, and thus ensuring the intensity of the heat field formed by microwaves in the cooking cavity 122, that is, ensuring the microwave heating effect on the food.
[0091] Furthermore, along the first direction, the distance between two adjacent recesses 114 is 0.15λ to 0.2λ, where λ is the wavelength of the microwave emitted by the microwave component 104.
[0092] Specifically, along the first direction, that is, along the length of the slit 108, the distance between two adjacent recesses 114 can be set to 0.15λ to 0.2λ. Here, λ represents the wavelength of the microwaves emitted by the microwave component 104 of the cooking appliance 100.
[0093] Specifically, taking a microwave oven as an example, the wavelength of the microwaves emitted by the microwave component 104 of the microwave oven is typically 192 mm. Correspondingly, the distance between two adjacent recesses 114 can be set from 0.15 × 192 mm to 0.2 × 192 mm, which is 28.8 mm to 38.4 mm. Specifically, in practical applications, the width of the gap 108 can be set to 36 mm.
[0094] By setting the distance between two adjacent recesses 114, the wavelength of the microwave can be matched to ensure the rational arrangement of multiple hollow parts on the plate 120, thereby ensuring the uniformity and intensity of the heat field distribution in the cooking cavity 122 and ensuring the effect of microwave heating.
[0095] In any of the above embodiments, such as Figure 1 As shown, a microwave inlet 126 is further provided on one side of the housing 102. The microwave assembly 104 includes: a magnetron 116, which is used to generate microwaves; a waveguide 118, the inlet of which is connected to the magnetron 116, the outlet of which is a microwave outlet 124, and a plate 120 covering the outlet of the waveguide 118.
[0096] In this embodiment, the microwave component 104 may specifically include a magnetron 116 and a waveguide 118, wherein the magnetron 116 is used to generate microwaves, and correspondingly, the waveguide 118 is used to conduct microwaves. Specifically, the inlet of the waveguide 118 is connected to the magnetron 116 so that the microwaves generated by the magnetron 116 can enter the waveguide 118. Further, the outlet of the waveguide 118 is the microwave outlet 124, through which the microwaves generated by the magnetron 116 can be output.
[0097] Correspondingly, a microwave inlet 126 can be provided on the housing 102 of the cooking appliance 100. By connecting the microwave outlet 124 of the waveguide 118 to the microwave inlet 126 on the housing 102, microwaves can be input into the cooking cavity 122 of the housing 102 to heat the food with microwaves.
[0098] Furthermore, the cooking appliance 100 includes a microwave oven.
