Problems solved by technology

Due to these two characteristics, electric ovens are inefficient
The main reason is that the electric heating wire at the bottom heats the air, and the hot air moves upwards. If the amount of food is small and the contact surface with the air is small, most of the hot air directly heats the top of the electric oven without touching the food and is discharged from the gap on the top, causing The top of the electric oven is very hot, and the food inside is not easy to cook for a long time
[0003] Even if the contact area with food is large, but the contact time is short and the energy given to food is limited, most of the energy is discharged as the hot air moves up
[0004] There is also a more serious problem: in order to reduce the impact of food on the heating resistance wire, there is generally a metal plate on the heating resistance wire, and the metal plate blocks the direct contact between the hot air and the food, resulting in most of the heat. Air moves up and out from the sides of the plate, and the side of the food that is in contact with the plate tends to burn

Embodiment 1

[0018] There are concave holes 1 under the baking frame, and the number of the concave holes is the same as the number of the heating resistance wires.

[0019] The frame body 2 of the baking rack is made of stainless steel. The two sides or four sides or three sides of the baking frame body 2 protrude to form a protruding part with two sides high or four sides high or three sides high. The inner side of the protruding part has air holes 3, and the heated air comes out from the air holes and sprays to the partition 4 on the food.

[0020] Because the heating air first acts on the dividing plate 4, the dividing plate is heated to increase the temperature of the dividing plate, and the remaining heat of the hot air can also come out from the vent holes to act on the food again, which improves the utilization efficiency of heat. At the same time, the partition also blocks the influence of food exudate on the heating wire.

Embodiment 2

[0022] There are concave holes 1 under the baking frame, and the number of the concave holes is the same as the number of the heating resistance wires.

[0023] The frame body 2 of the baking rack is made of stainless steel. Inside the baking rack, a dividing plate 4 is hung above the heating wire, and the dividing plate is a plate, which is high around, flat in the middle, and 2cm higher than the center in the surroundings, and plays the role of blocking the exudate heating wire of food.

[0024] The upper end of the baking frame frame body 2 is a plane, which is integrated with the baking frame, and is slightly higher around. The plane has air holes 3, and the heated air is sprayed to the food on the plane from the air holes.

[0025] Because the heating air first acts on the plane, the plane is heated to increase the temperature of the plane, and the remaining heat of the hot air can also come out from the vent holes to act on the food again, which improves the utilization ...

Abstract

The invention relates to a baking frame of an electric oven, and relates to the field of kitchen wares, in particular to a food utensil used for a baking oven. Air moves up after heated, thermal capacity of the air is small, and a food tray prevents food effusion from affecting a heating strip, so that efficiency of the electric oven is low. In order to improve energy utilization rate of the electric oven and prolong acting time of hot air, the invention designs the baking frame of the electric oven. The technical scheme includes that concave holes are formed in the bottom of the baking frame, the number and the positions of the concave holes are matched with those of the heating strips of the oven. A partition plate which is slightly high all around is arranged above the heating strips, and an air hole is formed in a heating frame. The baking frame of the electric oven has the advantages of preventing the hot air from moving up straightly, prolonging acting time of the hot air on food, and improving energy utilization efficiency of the baking oven.

Description

technical field [0001] The invention relates to the field of kitchen utensils, in particular to containers for placing food used in ovens. Background technique [0002] The characteristic of air is that it moves up after being heated, and the heat capacity of air is very small. Because of these two characteristics, electric ovens are inefficient. The main reason is that the electric heating wire at the bottom heats the air, and the hot air moves upwards. If the amount of food is small and the contact surface with the air is small, most of the hot air directly heats the top of the electric oven without touching the food and is discharged from the gap on the top, causing The top of the electric oven is very hot, and the inside of the food is not easy to cook for a long time. [0003] Even if the contact surface with food is large, but the contact time is short and the energy given to the food is limited, most of the energy is still discharged as the hot air moves up.
