Description

Technical Field

[0001] This utility model relates to the field of ovens, and in particular to an oven with hot air convection. Background Technology

[0002] As a common food processing device, the core function of an oven is to bake, roast, or heat food through heat transfer. Traditional ovens typically rely on heat radiation generated by heating elements (resistance wires or quartz tubes) and natural air convection within the cavity to transfer heat. However, natural convection is inefficient and results in uneven heat distribution, leading to significant differences in heating different parts of the food, such as a burnt surface while the inside remains uncooked, or requiring frequent adjustments to the baking tray to achieve even heating, resulting in a poor user experience.

[0007] In some embodiments, the middle part of the second heating tube has a wavy structure.

[0008] In some embodiments, the centrifugal fan unit includes two centrifugal fans, each centrifugal fan being disposed on the rear side of the air outlet grille. The output end of the centrifugal fan is provided with a guide vane, the guide vane including a base plate parallel to the air outlet grille, and a plurality of guide vanes perpendicular to the base plate being evenly distributed along the edge of the base plate.

[0009] In some embodiments, the convection plate is vertically disposed at the rear of the inner cavity, and the left and right sides of the inner cavity are respectively provided with storage slots for placing trays or grills.

[0010] In some embodiments, the tilt angle of the first guide vane and the second guide vane is 30° to 60°.

[0011] In some embodiments, two air inlets are provided on the left and right sides of the air outlet group along the vertical direction.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] This application utilizes the combined action of the air outlet group in the middle of the rear side of the inner cavity, the air inlet holes on both sides, and the centrifugal fan group to form a circulating air channel on both sides of the inner cavity of the oven, forming a three-dimensional circulation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] refer to Figures 1 to 7This application provides an oven with hot air convection, comprising: an oven body 1 having an inner cavity 2; a heating mechanism including a first heating tube 3 and a second heating tube 4, the first heating tube 3 surrounding the top edge of the inner cavity 2, and the second heating tube 4 being disposed in the middle of the top surface of the inner cavity 2; and a convection mechanism including a convection plate 5 and a centrifugal fan unit 6, the convection plate 5 being disposed in the rear of the inner cavity 2, the convection plate 5 having an air outlet group 7 disposed in the middle of the convection plate 5, the centrifugal fan unit 6 being disposed behind the air outlet group 7, and air inlets 8 being disposed on both sides of the convection plate 5.

[0023] The first heating tube 3 heats the entire inner cavity, while the second heating tube 4 enhances the heating effect on the circulating airflow.

[0024] In some embodiments, a first guide plate 9 is inclinedly arranged on the inner side of the air inlet 8 and faces outward, and a second guide plate 10 is inclinedly arranged on the outer side of the air inlet 8 and faces inward. The arrangement of the first guide plate 9 enables the air inlet 8 to guide and draw the gas from the outer edge of the inner cavity 2 into the centrifugal fan unit 6 when drawing air. Together with the air outlet group 7 arranged in the middle, a circulating air channel is formed between the inner cavity 2 of the oven and the centrifugal fan unit 6. The second guide plate 10 can quickly guide the gas drawn in by the air inlet 8 to the centrifugal fan unit 6.

[0025] In some embodiments, the air outlet group 7 includes two parallel air outlet grilles, each air outlet grille having multiple annular air outlet grooves 11 with gradually increasing radii. The edges of the annular air outlet grooves 11 are arc-shaped structures 12. The annular air outlet grooves 11 and their arc-shaped edges 12 cooperate to expand the angle at which the air is blown out.

[0026] In some embodiments, the middle part of the second heating tube 4 has a wavy structure, which increases the contact area with the annular circulating air duct formed by the inner cavity 2 and improves the heating efficiency.

[0027] In some embodiments, the centrifugal fan unit 6 includes two centrifugal fans 13, each centrifugal fan 13 is correspondingly arranged on the rear side of the air outlet grille, and the output end of the centrifugal fan 13 is provided with a guide fan blade. The guide fan blade includes a base plate 14 parallel to the air outlet grille, and multiple guide vanes 15 perpendicular to the base plate 14 are evenly distributed on the edge of the base plate 14, which can quickly draw in the gas from the air inlets 8 on both sides and blow it vertically toward the air outlet group 7, thereby improving the circulation efficiency.

[0028] In some embodiments, the convection plate 5 is vertically disposed at the rear of the inner cavity 2, and the left and right sides of the inner cavity 2 are respectively provided with storage slots 16 for placing trays or grills.

[0029] In some embodiments, the tilt angle of the first guide plate 9 and the second guide plate 10 is 30° to 60°.

[0030] In some embodiments, two air inlets 8 are provided on the left and right sides of the air outlet group 7 in the vertical direction to increase the longitudinal range of the circulating air duct.

[0031] During operation, the centrifugal fan unit 6 drives the gas circulation in the inner cavity 2, forming two annular circulating air channels on the left and right sides within the inner cavity 2. The wave-shaped second heating pipe 4 heats the annular circulating air channels, thereby improving heating efficiency.

[0032] This application utilizes the combined action of the air outlet group 7 at the rear center of the inner cavity 2, the air inlet 8 on both sides, and the centrifugal fan group 6 to form a circulating air duct on both sides of the inner cavity 2, creating a three-dimensional circulation. When the heating mechanism is working, it radiates heat to the circulating air duct, so that hot air covers every corner of the inner cavity 2 of the oven, eliminating the "low temperature dead corner" of traditional ovens and making the food heated more evenly.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
