Cooking electric appliance with hot air circulating channel

Abstract

The invention provides a cooking electric appliance with a hot air circulating channel. The cooking electric appliance comprises a shell, a cavity is arranged in the shell, the cavity is defined by athermal insulation wall, a food basket is arranged in the cavity, a heating element and a centrifugal fan are arranged above the food basket, the thermal insulation wall comprises an upper thermal insulation wall and a lower thermal insulation wall, an electrical cavity is formed at the inner side of the upper thermal insulation wall, and an energy collecting cavity is form between the bottom of the lower thermal insulation wall and the bottom of the food basket; the electrical cavity communicates with the energy collecting cavity, the inside of the food basket communicates with the electricalcavity and the energy collecting cavity, and thus the hot air circulating channel is formed; and the bottom of the food basket is hyperboloid-shaped, the bottom of the lower thermal insulation wall is composed of a hyperboloid, a plane and an arc face, and the distance between the center of the bottom of the energy collecting cavity and the center of the bottom of the food basket is greater thanor equal to the distance between the periphery of the bottom of the energy collecting cavity and the periphery of the bottom of the food basket. For the cooking electric appliance provided by the invention, the heating of food is uniform, meanwhile, the rapid heating of the food can be realized, in addition, the cooking electric appliance is simple in structure, the manufacturing difficulty is reduced, and thus the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to a cooking appliance, in particular to a cooking appliance with a hot air circulation channel. Background technique [0002] Barbecue food is loved by people because of its unique taste. There are many types of air fryers on the market now, their performance and taste are uneven, and oily stains are not convenient to clean. Most people prefer the ones baked with wood fire. Food taste, in view of this feature, it is urgent to invent a product with faster performance and cooking efficiency, and the baking taste is closer to the effect of firewood baking. This equipment has the characteristics of cooking food without cooking oil, which not only ensures the food Taste can make people enjoy food healthily again. However, the air fryers on the market have the following disadvantages: 1. The air fryer does not have a fluid structure, but a small rounded corner is made around it.

[0002] Barbecue food is loved by people because of its unique taste. There are many types of air fryers on the market now, their performance and taste are uneven, and oily stains are not convenient to clean. Most people prefer the ones baked with wood fire. Food taste, in view of this feature, it is urgent to invent a product with faster performance and cooking efficiency, and the baking taste is closer to the effect of firewood baking. This equipment has the characteristics of cooking food without cooking oil, which not only ensures the food The taste can make people enjoy the food healthily

However, the air fryers on the market have the following disadvantages: 1. The air fryer does not have a fluid structure, but a small rounded corner is made around it. When the hot air circulates, it is not conducive to the introduction of hot air into the middle, and the hot air is all accumulated around the lower part of the inner pot. , causing the food to be cooked differently around and in the middle, the surroundings are browned, and the center is not cooked; 2. The bottom surface of the food basket is flat, resulting in uneven food ripening; 3. The bottom surface of the food basket is flat, causing the food basket to be inconsistent with The space at the bottom of the inner pot is small, so it cannot gather energy; 4. The large bottom surface of the food basket is flat. When cooking food, it is too close to the bottom, so that the hot air cannot enter the back of the food, resulting in different degrees of cooked food from top to bottom. The phenomenon of whitish color; 5. The large bottom of the food basket is flat, so the space between the food basket and the bottom of the inner pot is small, and a lot of hot air collides with the food and refracts back. The force of the fan makes the hot air accumulate around the lower part of the inner pot, causing food The surrounding food color is darker and duller than the center food color

Although this cooking utensil can solve the problem of uneven heating of air fryers on the market, the structure of the cooking utensil is too complicated, the manufacturing cost is high, and it is very inconvenient to clean
