[0002] Currently, in the market, many cooking appliances, such as the hot air function of an electric oven, adopt a rear - type hot air heating method. The principle of this heating method is as Figure 1 shown. The air in the oven cavity is inhaled from the air holes in the middle area of the air outlet cover by a fan and then blown towards the heating tube. After being heated by the heating tube, it enters the oven cavity through the side air holes of the air outlet cover, forming a hot air circulation. In this technology, the air inlet area of the air outlet cover can only be in the circular area at the center of the fan, with a limited air intake range. And at the edge of the air inlet area, since it is at the edge of the fan, air intake is not smooth, easily forming turbulent flow and unable to form an effective circulating convection.

[0003] Therefore, in the prior art, the above - mentioned technical solution cannot form an effective circulating convection, making it difficult for the temperature in each part of the oven cavity to reach uniformity, thus affecting the use effect of the cooking appliance. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is that in the prior art, the cooking appliance cannot form an effective circulating convection, making it difficult for the temperature in each part of the oven cavity to reach uniformity. Thus, a cooking appliance is provided.

[0005] To achieve the above object, an embodiment of the present invention provides a cooking appliance, which includes: a housing with a cooking space arranged inside; an air outlet cover arranged on the inner wall of the housing, an installation cavity is arranged between the air outlet cover and the inner wall, a fan and a heating component installed around the fan are arranged in the installation cavity; the air outlet cover is provided with an air inlet, and the circumferential edge of the air outlet cover is provided with air outlets; a wind - collecting cover arranged on the air outlet cover; the wind - collecting cover is adapted to cover the air inlet, and a gap is arranged between the wind - collecting cover and the air outlet cover; the wind - collecting cover is provided with air inlet holes.

Obviously, the described embodiments are some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] Currently, in the market, many cooking appliances, such as the hot air function of an electric oven, adopt a rear - type hot air heating method. The principle of this heating method is, as Figure 1 shown, the air in the oven cavity is sucked from the air holes in the middle area of the air outlet cover by a fan and then blown towards the heating tube. After being heated by the heating tube, it enters the oven cavity through the side air holes of the air outlet cover, forming a hot air circulation. In this technology, the air inlet area of the air outlet cover can only be in the circular area at the center of the fan, with a limited air intake range. And at the edge of the air inlet area, because it is at the edge of the fan, the air cannot enter smoothly, easily forming turbulence and unable to form an effective circulating convection. Therefore, in the prior art, the above - mentioned technical solution cannot form an effective circulating convection, making it difficult to achieve uniform temperature everywhere in the oven cavity, which affects the use effect of the cooking appliance.

[0030] Therefore, the technical problem to be solved by the present invention is that in the prior art, the cooking appliance cannot form an effective circulating convection, making it difficult to achieve uniform temperature everywhere in the oven cavity, and thus provides a cooking appliance.

[0031] Embodiment 1

[0032] As Figure 2 and Figure 3 shown, the embodiment of the present invention provides a cooking appliance, which includes: a housing, an air outlet cover 1, and an air collecting cover 6.

[0033] Specifically, in an embodiment of the present invention, a cooking space is provided inside the shell, and an air outlet hood 1 is provided on the inner wall of the shell, and there is a certain space between the air outlet hood 1 and the inner wall, and an installation cavity may be provided between the air outlet hood 1 and the inner wall, and a fan 3 and a heating component 2 installed around the fan 3 are also provided in the installation cavity, and the heating component 2 may be a heating tube. The air outlet hood 1 is provided with an air inlet 11, and an air outlet 4 is provided on the circumferential edge of the air outlet hood 1. An air collecting hood 6 is provided on the air outlet hood 1, and the air collecting hood 6 is suitable for covering the air inlet 11, and a certain gap 12 is provided between the entire air collecting hood 6 and the air outlet hood 1, and an air inlet hole 5 is at least partially opened on the air collecting hood 6. The air inlet 11 can be expanded and its position can be changed according to actual needs.

[0034] With such arrangement, the air in the furnace cavity is first sucked in from the air inlet 5 of the air collecting cover 6 and the gap 12 at the edge, then enters the fan 3 through the air inlet 11 of the air outlet cover 1, and then blows toward the heating component 2. After being heated by the heating component 2, the air enters the furnace cavity through the air outlet 4 at the circumferential edge of the air outlet cover 1, forming a hot air cycle. This allows the fan 3 to smoothly enter the air, thereby improving the circulation effect of the hot air.

[0035] Further, in a preferred embodiment of the present invention, a rectifier cavity 10 is formed between the air collecting hood 6 and the air outlet hood 1. Specifically, a certain recessed area can be stamped in the area of ​​the air outlet hood 1 corresponding to the air collecting hood 6, and after the air collecting hood 6 is installed on the air outlet hood 1, a certain cavity is formed between the recessed area and the air collecting hood 6, and the cavity is the rectifier cavity 10.

[0036] At the same time, at most part of the air inlet holes 5 overlap with the air inlet port 11. That is to say, only part of the air inlet holes 5 overlap with the air inlet port 11, or the air inlet holes 5 do not overlap with the air inlet port 11 at all. An air inlet area is provided on the air collecting hood 6, and a plurality of air inlet holes 5 are provided in the air inlet area. For example, part of the air inlet holes 5 in the air inlet area may be staggered with the air inlet port 11, so that only part of the air inlet holes 5 overlap with the air inlet port 11. The air inlet area may also be completely staggered with the air inlet port 11, so that the air inlet area overlaps with the recessed area of ​​the air outlet hood 1. Of course, multiple air inlet areas may also be provided, and only part of the air inlet areas may be completely staggered with the air inlet port 11. Those skilled in the art may change the setting position of the air inlet area according to actual conditions, and this embodiment does not limit this.

[0037] Specifically, Figure 2 As shown by arrow A, Figure 2 The flow path of the airflow into the cooking appliance is given in Figure 2As can be seen, the airflow flowing in through the air inlet holes 5 first collides with the peripheral baffle of the air inlet 11, then turns and enters the air inlet 11, and then further flows into the cooking utensil.

[0038] Of course, this embodiment is only an example of the formation method of the rectifying cavity 10. For example, the part of the air collecting hood 6 except the edge can also be stamped to form a certain concave area, and there is a certain cavity between the concave area and the air inlet hood, and this cavity is the rectifying cavity 10. However, this embodiment does not limit this, and those skilled in the art can change the formation method of the rectifying cavity 10 according to the actual situation as long as the same technical effect can be achieved.

[0039] In the embodiment of the present invention, by forming a rectifying cavity 10 between the air collecting hood 6 and the air outlet hood 1, the air in the furnace cavity can be first sucked in from the air inlet holes 5 and the gaps 12 at the edge of the air collecting hood 6, and then the sucked air will directly hit the air outlet hood 1 and then enter the rectifying cavity 10 to collect and store the sucked air. At the same time, the sucked air can be rectified, and then through the air inlet 11 of the air outlet hood 1, it enters the fan 3, and then blows to the heating component 2. After being heated by the heating component 2, it enters the furnace cavity through the air outlet 4 at the circumferential edge of the air outlet hood 1 to form a hot air circulation. Compared with directly passing through the air inlet holes 5 and the air inlet 11 in the prior art, this technical solution can make the air inlet of the fan 3 smooth and improve the circulation effect of the hot air.

[0040] Further, in an optional embodiment of the present invention, the air inlet 11 is arranged in the air inlet direction of the fan 3, and the air inlet 11 is located at the center of the air outlet hood 1. The air inlet 11 can be circularly arranged.

[0041] In an optional embodiment of the present invention, the air outlet hood 1 can be rectangular or circularly arranged, and a plurality of the air outlets 4 are evenly arranged on the edge of the rectangle or the circle. With such an arrangement, the hot air after being heated by the heating component 2 can enter the cooking space through the plurality of air outlets 4 evenly arranged on the edge, thereby forming a hot air circulation.

[0042] Further, in an optional embodiment of the present invention, a fixing bracket 7 is arranged on the inner wall, and the air outlet hood 1 is fixed on the fixing bracket 7 through a fixing member. The fixing member can be a screw 9.

[0043] Of course, this embodiment is only an example of the fixing method of the air outlet hood 1, but it does not limit this, and those skilled in the art can change the fixing method of the air outlet hood 1 according to the actual situation as long as the same technical effect can be achieved.

[0044] In an alternative embodiment of the present invention, the air collecting hood 6 is connected to the air outlet hood 1 through a connecting member. The connecting member can be a snap structure, and the snap structure includes a buckle ear 8 and a buckle groove. The buckle ear 8 is provided on one of the air collecting hood 6 and the air outlet hood 1, and the buckle groove is provided on the other of the air collecting hood 6 and the air outlet hood 1. When the buckle ear 8 is provided on the air collecting hood 6, the buckle groove is provided in the middle area of the air outlet hood 1, so that the buckle ear 8 is buckled in the middle of the air outlet hood 1, completely separating the middle part and the surrounding part inside the air outlet hood 1. This can make the air in the furnace cavity only be first sucked in from the air inlet holes 5 and the gaps 12 at the edge of the air collecting hood 6, then enter the rectifying cavity 10 to rectify the sucked air, and then pass through the air inlet 11 of the air outlet hood 1, enter the fan 3, and then be blown towards the heating component 2. After being heated by the heating component 2, it enters the furnace cavity through the air outlet 4 at the circumferential edge of the air outlet hood 1, forming a hot air circulation.

[0045] Furthermore, in an alternative embodiment of the present invention, the air outlet hood 1 and the air collecting hood 6 are made of a metal material and are formed by stamping. Specifically, the air outlet hood 1 and the air collecting hood 6 can be formed by stamping a metal sheet with a thickness of 0.4 to 1 mm, and the material can be made of aluminum, stainless steel, or other iron plates with coatings or layers. The air collecting hood 6 is on the side of the air outlet hood 1 away from the fan 3. The air collecting hood 6 and the air outlet hood 1 can be directly welded into one body, or can be separately installed in sequence.

[0046] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For ordinary workers in the relevant field, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
