Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, and particularly relates to a hot air cooking appliance. Background Art

[0002] The utility model patent with the Chinese patent number CN202321276404.4 discloses an air fryer, which includes a housing. An upper cooking cavity and a lower cooking cavity are independently arranged in the housing. There is one or more lower cooking cavities and one or more upper cooking cavities. A first pot body assembly is arranged in the lower cooking cavity, and a second pot body assembly is arranged in the upper cooking cavity.

The pot body through holes 5 and the hot air guide holes 4 are interconnected.

[0028] In this embodiment, by relying on the connection between the rear end of the pot body 1 and the front end of the hot air chamber 3, and by making the pot body through-hole 5 communicate with the hot air guide hole 4, the hot air in the hot air chamber 3 can directly and quickly enter the pot body 1. This not only effectively reduces the flow path of the hot air and avoids heat loss, but also ensures that the hot air can directly act on the food in the pot body 1, thus quickly baking and cooking the food, effectively improving the thermal efficiency, reducing energy consumption, and having strong practicability.

[0029] A wind guide plate 6 is arranged between the inner container 2 and the hot air chamber 3. The wind guide plate 6 is convexly provided with a wind collecting groove 7 towards the inner container 2. A number of hot air guide holes 4 are arranged on the wind collecting groove 7. The rear wall of the pot body 1 is convexly provided with an air inlet groove 8 towards the inner container 2. The shape of the air inlet groove 8 corresponds to the shape of the wind collecting groove 7 and they rely on each other. A number of pot body through-holes 5 are arranged on the air inlet groove 8.

[0030] In this embodiment, both the wind collecting groove 7 and the air inlet groove 8 are convexly arranged in the same direction. At the same time, they rely on each other, and after relying on each other, they are communicated with each other through the pot body through-hole 5 and the hot air guide hole 4 to reduce the path of the hot air in the hot air chamber 3 entering the pot body 1, so that the hot air in the hot air chamber 3 can directly and quickly enter the pot body 1. In addition, the setting of the wind collecting groove 7 can facilitate the collection of hot air, reduce the turbulent flow caused by the hot air swirling in the hot air chamber 3, improve the flow speed and flow volume of the hot air, and further improve the thermal efficiency of food baking and cooking.

[0031] A hot air hood 9 is arranged on the wind guide plate 6. The hot air hood 9 is fixed at the rear side of the wind guide plate 6 and a hot air chamber 3 is formed between them. A hot air device is arranged on the hot air hood 9. The hot air generated by the hot air device enters the pot body 1 directly through the hot air guide hole 4 and the pot body through-hole 5.

[0032] Specifically, the hot air device includes a heating element 10, a hot air fan 11, a driving motor 12, and a motor bracket 13. Among them, the motor bracket 13 is convexly provided with a bracket groove 14 towards the direction away from the inner container 2. The hot air hood 9 is fixedly arranged in the bracket groove 14. The driving motor 12 is fixedly arranged on the motor bracket 13 and its driving end extends towards the inner container 2 and passes through the motor bracket 13 and the hot air hood 9. The heating element 10 is fixedly arranged on the hot air hood 9. The hot air fan 11 is located at the rear side of the heating element 10. The driving motor 12 is drivingly connected to the hot air fan 11.

[0034] When the driving motor 12 is working, it drives the hot air fan 11 and the cooling fan 16 to rotate simultaneously. When the hot air fan 11 rotates, it blows the heat generated by the heating element 10 from the hot air cavity 3 through the hot air guide holes 4 and the pot body through holes 5 into the pot body 1 to bake the food in the pot body 1. When the cooling fan 16 rotates, it blows the heat transferred from the hot air cavity 3 into the cooling cavity 15 to dissipate the heat of the entire hot air device and ensure its normal operation.

[0035] Correspondingly, a plurality of support through holes are provided on the motor support 13, and the plurality of support through holes are communicated with the cooling cavity 15 to facilitate the cooling fan 16 to blow the heat in the cooling cavity 15 outside the cooling cavity 15.

[0036] An electric control support 17 is also fixedly provided on the motor support 13, and an electric control board 18 is fixedly provided on the electric control support 17. The electric control board 18 is electrically connected to the heating element 10 and the driving motor 12 respectively, thereby realizing the control of the heating element 10 and the driving motor 12.

[0037] A temperature sensor 19 is provided in the hot air cavity 3, and the temperature sensor 19 is fixedly provided on the hot air cover 9 or the motor support 13.

[0038] In this embodiment, the temperature sensor 19 is fixedly provided on the support groove 14 of the motor support 13, and its sensing end extends into the hot air cavity 3 to detect the temperature in the hot air cavity 3. The electric control board 18 is electrically connected to the temperature sensor 19 to obtain the temperature in the hot air cavity 3, ensuring that the hot air device can act at a stable temperature and avoiding product damage caused by high temperature.

[0039] The air inlet groove 8 is provided on the entire rear wall of the pot body 1, and a plurality of pot body through holes 5 are evenly distributed on the air inlet groove 8. The size of the air collecting groove 7 is equivalent to the size of the air inlet groove 8. The heating element 10 is located directly behind the air collecting groove 7 and there is a gap between the two.

[0040] In this embodiment, the entire rear wall of the pot body 1 is convexly provided with the air inlet groove 8, and at the same time, a plurality of pot body through holes 5 are evenly distributed on the air inlet groove 8. In addition, an air collecting groove 7 with a size equivalent to that of the air inlet groove 8 is provided on the air guide plate 6, thereby greatly improving the speed and air volume of the hot air entering the pot body 1 from the hot air cavity 3.

[0041] The main body of the machine includes a housing 20, a bottom shell 21 and a door lining plate 22. Among them, the front side and the bottom of the housing 20 are open. The bottom shell 21 is fixedly provided at the bottom of the housing 20. The inner liner 2 and the hot air device are respectively fixedly provided in the housing 20.

A handle 24 is provided on the front side of the pot body 1, and the pot body 1 is laterally movably disassembled and assembled on the inner liner 2 through the door opening 23.

[0042] In this embodiment, the pot body 1 is disassembled and assembled on the inner pot 2 by means of lateral pushing and pulling. In addition, the handle 24 is provided to facilitate the user's lateral pushing and pulling operation of the pot body 1, and the door liner 22 can improve the overall appearance integrity and aesthetics of the product.

[0043] For the convenience of heat dissipation, a number of housing heat dissipation holes are respectively provided on the left and right sides and the rear side of the housing 20. The heat conducted to the outside of the heat dissipation cavity 15 by the heat dissipation fan 16 is discharged out of the main body of the host through the number of housing heat dissipation holes, ensuring the heat dissipation effect of the product.

[0044] A hollow shelf 25 for receiving food is disassembled and assembled in the pot body 1. The hot air in the hot air cavity 3 enters the pot body 1 and fully cooks the food on the hollow shelf 25.

[0045] In this embodiment, the setting of the hollow shelf 25 not only facilitates the placement of food, but also divides the inside of the pot body 1 into upper and lower areas, and the upper and lower areas are interconnected by the hollow positions of the hollow shelf 25. When the hot air enters the inside of the pot body 1 from the rear side, it can act on the upper and lower surfaces of the food in the upper and lower areas at the same time, so that any position on the surface of the food can be heated simultaneously, enabling the user not to turn over the food during cooking, improving the use experience, and at the same time greatly improving the baking cooking efficiency of the food, while also ensuring the uniform heating of the food and the baking cooking effect of the food.
