[0036] In order to better illustrate the present invention, the present invention is further described in detail below with reference to the accompanying drawings.

[0037] It should be clear that the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the embodiments of the present application.

The character " / " generally indicates that the associated objects are in an "or" relationship.

[0041] Microwaves have the characteristics of short transmission distance, large propagation loss in the air, reflection on metal, absorption and heating on water and food. Microwave cooking equipment is a device that uses a magnetron to emit high-frequency microwaves, and then transmits the high-frequency microwaves to the cooking cavity through a waveguide box to achieve microwave heating of food in the cavity, such as microwave ovens, steam ovens with microwave functions, steam ovens, integrated stoves or cooking centers, etc. Including but not limited to desktop models or embedded models.

[0042] Because excessive microwaves have certain effects on human health, people hope to avoid microwave leakage as much as possible, or control the amount of microwave leakage within a certain range. In addition, in order to improve the cooking effect, people also hope to improve the microwave conduction efficiency as much as possible.

[0043] In order to reduce microwave leakage, the applicant disclosed a waveguide box in the Chinese utility model patent CN218957998U, which effectively improved the anti-microwave leakage effect of the waveguide box by improving the waveguide box. Although the anti-microwave leakage effect of the waveguide box has been significantly improved, some microwave cooking equipment still has the problem of large microwave leakage during actual production testing.

[0044] In order to solve this technical problem, an embodiment of the present application provides a microwave cooking component to at least improve the effect of preventing microwave leakage.

[0045] like Figure 1-8 As shown, a microwave cooking assembly of an exemplary embodiment of the present application includes:

[0046] A waveguide box having a microwave outlet, wherein the periphery of the microwave outlet has a first flange;

[0047] A cooking cavity having a microwave inlet, wherein the periphery of the microwave inlet has a second flange;

[0048] When the waveguide box is connected to the cooking cavity, the first flange is inserted into the microwave inlet, and the first flange is tightly attached to the second flange;

[0049] The first flange and the second flange are connected by welding to seal the gap between the first flange and the second flange.

[0050] Compared with the prior art, the present application provides a first flange at the microwave outlet of the waveguide box and a second flange at the microwave inlet of the cooking cavity, further inserts the first flange into the microwave inlet so that it is tightly attached to the second flange, and then seals the gap between the first flange and the second flange by welding to prevent microwaves from leaking from the gap between the first flange and the second flange.

[0051] Among them, Figure 1-6 As shown, the waveguide box 100 has a microwave outlet 110, and a first flange 120 is provided at the periphery of the microwave outlet. Specifically, the first flange 120 is protrudingly arranged on the bottom surface of the waveguide box 100 to form an external connection portion. The first flange 120 includes a first external connection surface 121, a first end surface 122 connected to the first external connection surface, and a first inner side surface 123 connected to the first end surface. Microwaves are emitted from the microwave outlet 110, and part of the microwaves are reflected by the first inner side surface 123 and then emitted. The thickness of the waveguide box is 0.5-1.5mm. The thickness of the first flange is 0.5-1.5mm. Preferably, the thickness of the waveguide box body is 0.8mm, and the thickness of the first flange is 0.8mm.

[0052] Among them, Figure 1-6As shown, the cooking cavity 200 has a microwave inlet 210, and the periphery of the microwave inlet has a second flange 220. Specifically, the second flange 220 is protrudingly arranged on the inner surface of the cooking cavity 200 to form an inner connecting portion. The second flange 220 includes a second inner connecting surface 221, a second end surface 222 connected to the second inner connecting surface, and a second outer side surface 223 connected to the second end surface. The thickness of the cooking cavity is 0.3-1.0mm. The thickness of the second flange is 0.3-1.0mm. Preferably, the thickness of the cooking cavity is 0.5mm. The thickness of the second flange is 0.5mm.

[0053] When the waveguide box 100 and the cooking cavity 200 are connected together, the first flange 120 is inserted into the microwave inlet 210, and the first flange 120 and the second flange 220 are in close contact. Figure 1-6 As shown, after the first flange is inserted into the microwave inlet, the outer portion of the waveguide box is connected to the inner portion of the cooking cavity. The second inner surface 221 is tightly attached to the first outer surface 121, and a gap 300 is formed between the first flange and the second flange at the junction of the two.

[0054] In the prior art, in order to connect and fix the cooking cavity and the waveguide box, bolts or screws are generally used for connection and fixation. However, due to the existence of gaps in screw holes and the like in the connection methods such as screws or screws, microwaves can easily escape through the gaps and cause microwave leakage. To this end, in the embodiment of the present application, a first flange 120 is provided at the microwave outlet 110 of the waveguide box 100, and a second flange 220 is provided at the microwave inlet 210 of the cooking cavity 200. By inserting the first flange 120 into the microwave inlet 210, and the first flange 120 and the second flange 220 are closely attached together, on the one hand, it is possible to subsequently connect the first flange and the second flange by welding the cooking cavity and the waveguide box; on the other hand, the first flange and the second flange are closely attached together, and the thickness increases after the two overlap, which can effectively avoid welding penetration caused by insufficient thickness of the first flange or the second flange.

[0055] Since the first flange and the second flange are both located in the cooking cavity, it is still difficult to achieve welding in the limited space of the cavity. In order to achieve the first flange and the second flange in the limited space of the cooking cavity, it is preferred that the first end face 122 and the second end face 222 of the embodiment of the present application have a distance d to form a welding position 310 between the first end face and the second end face. After welding, at least the first end face and the second end face can be melted into one body to seal the gap 300 between the first flange and the second flange. Figure 2-6It should be noted that by setting the first end face and the second end face at a distance, the first end face to the second end face is stepped, and then a stepped welding position is formed between the first end face and the second end face, making welding easier.

[0056] Preferably, in the embodiment of the present application, the welding position is located in the cooking cavity and outside the microwave outlet, and is formed on the second outer side surface 223, the second end surface 222, the first external connection surface 121 and the first end surface 122. That is, after the first flange is inserted into the microwave inlet, the distance from the first end surface to the bottom surface of the waveguide box is greater than the distance from the second end surface to the bottom surface of the waveguide box. In this way, although the welding position is still located in the cooking cavity, since the welding position faces outward, it can provide a certain degree of convenience for the welding gun to be inserted into the cooking cavity to weld the welding position, making it possible to weld the welding position in the cooking cavity.

[0057] It should be noted that the sealing described in the embodiment of the present application should be understood as at least being able to prevent microwaves from leaking from the gap. Preferably, the first end face and the second end face are fused together, and microwaves can be reflected back into the cooking cavity when they contact the fused first end face and the second end face.

[0058] Of course, it is also possible to arrange the welding position to be located inside the microwave outlet, and the welding position is formed on the first inner side surface, the first end surface, the second inner connecting surface and the second end surface.

[0059] In another exemplary embodiment, Figure 1-8 As shown, the microwave cooking assembly of the present application further includes: a waveguide box mounting plate 400, which is located between the waveguide box 100 and the cooking cavity 200, and connects the waveguide box and the cooking cavity.

[0060] The waveguide box mounting plate 400 has a mounting opening 410 , and the first flange 120 is inserted into the mounting opening 410 and the microwave inlet 210 and is in close contact with the second flange 220 .

[0061] like Figure 7 As shown, there are a plurality of first welding points 430 between the waveguide box mounting plate 400 and the cooking cavity 200 to seal the gap between the waveguide box mounting plate and the cooking cavity. This further prevents microwaves from escaping and leaking from the gap between the mounting plate and the cooking cavity. Preferably, the plurality of first welding points are arranged into at least one circle, the circle is arranged around the mounting opening, and the distance between two adjacent welding points in the same circle is less than or equal to 18 mm. On the one hand, by arranging the plurality of welding points in a circle around the mounting opening, and having a certain distance between two adjacent welding points, it is possible to reduce welding points as much as possible and reduce costs while effectively preventing microwaves from escaping and leaking.

[0062] like Figure 8 As shown, there are a plurality of second welding points 420 between the waveguide box mounting plate 400 and the waveguide box 100 to seal the gap between the waveguide box mounting plate and the waveguide box. Further prevent microwaves from escaping and leaking from the gap between the waveguide box mounting plate and the waveguide box. Preferably, the plurality of second welding points are arranged into at least one circle, the circle is arranged around the mounting port, and the distance between two adjacent welding points in the same circle is less than or equal to 18 mm. On the one hand, by arranging the plurality of welding points in a circle around the mounting port, and having a certain distance between two adjacent welding points, it is possible to reduce welding points as much as possible and reduce costs while effectively preventing microwaves from escaping and leaking. The sealing described in the embodiments of the present application should be understood as at least being able to prevent microwaves from leaking from the gap.

[0063] It should be noted that the multiple first welding points between the waveguide box mounting plate and the cooking cavity and the multiple second welding points between the waveguide box mounting plate and the waveguide box do not necessarily exist at the same time. In some embodiments, multiple first welding points may be provided only between the waveguide box mounting plate and the cooking cavity, and in other embodiments, multiple second welding points may be provided only between the waveguide box mounting plate and the waveguide box; in other embodiments, multiple first welding points are provided between the waveguide box mounting plate and the cooking cavity, and multiple second welding points are provided between the waveguide box mounting plate and the waveguide box.

[0064] In another exemplary embodiment, Figure 1 As shown, the microwave inlet is opened at the top of the cooking cavity, and the top of the cooking cavity has a protrusion 230 to form a storage space 240 inside the cooking cavity. The storage space is used to accommodate components such as microwave stirring blades. Preferably, the vertical section of the protrusion 230 is trapezoidal, and the upper bottom surface of the trapezoid is smaller than the lower bottom surface. The protrusion is set in a trapezoidal shape, and after the microwave enters the storage space from the microwave inlet, it contacts and reflects with the inner wall of the cooking cavity and enters various positions of the cooking cavity, making the microwave conduction efficiency higher and more uniform. Among them, preferably, the protrusion 230 includes a top surface 232 and an inclined side surface 231, and the angle between the side surface and the top surface is 30-60 degrees. The preferred angle between the side surface and the top surface is 45 degrees. Preferably, the extension line of the side surface intersects at the middle of the side of the cooking cavity, at which time the microwave conduction efficiency is optimal and the microwave is more uniform at various positions in the bottom cooking cavity.

[0065] An embodiment of the present application also provides a microwave cooking device, comprising the microwave cooking component of the above embodiment.

Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model.
