Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen utensils, in particular to a door body and a cooking equipment. BACKGROUND

[0002] A box-type cooking equipment (for example, a steamer, an oven, a steaming oven, or a micro steaming oven) usually comprises an inner container, a box body, and a door body. The inner container is arranged in the box body, and the inner container has an opening through which food is put into or taken out of the inner container. The door body is movably connected to the box body to open and close the inner container. During cooking, a large amount of heat is generated in the inner container, and the heat is transferred to the door body to cause temperature rise of the door body. Therefore, an air inlet and an air outlet are formed in the door body. Cold air from the outside enters the door body through the air inlet, and the cold air gradually becomes hot air by being heated. The hot air leaves the door body through the air outlet, thereby taking away the heat in the door body, so as to reduce the temperature rise of the door body and prevent the user from being scalded by the high temperature of the door body.

[0003] In the prior art, in order to prevent the liquid drops (for example, water drops or oil drops) falling from top to bottom from entering the inside of the door body through the air outlet, the air outlet is usually formed on the left side and / or the right side of the door body. The natural flow direction of the hot air is upward. The higher the position of the air, the more heat the air absorbs. The hot air is discharged from the higher position, and the more heat the air takes away. Therefore, the upper part of the air outlet has a better heat dissipation effect, and the lower part of the air outlet has a poor heat dissipation effect. In order to improve the heat dissipation performance of the door body, the air outlet should be located as high as possible. However, the area of the upper part of the left side and / or the right side of the door body is limited. Therefore, the area of the upper part of the air outlet is small, which leads to poor heat dissipation performance of the door body in the prior art, and is not conducive to reducing the temperature rise of the door body.

[0004] Therefore, it is necessary to provide a door body and a cooking equipment aiming at the above problems.

In the door body, the first air outlets are all located at the upper position, and the hot air discharged from each of the first air outlets absorbs more heat, in other words, the hot air discharged from each of the first air outlets takes away more heat. Therefore, the heat dissipation effect of each of the first air outlets is good, which makes the heat dissipation performance of the door body good and can effectively reduce the temperature rise of the door body.

[0014] In one of the embodiments, the first air outlets are located directly behind the outer glass door panel.

[0016] In one of the embodiments, the height difference between the top side of the outer glass door panel and the upper edge of the first air outlet is D, and D satisfies: D≥20mm.

[0017] In this way, the outer glass door panel can block the liquid from the front of the door body and prevent the liquid from the front of the door body from entering the inside of the door body through the first air outlets.

[0030] In this way, the position of the second air outlet is also relatively high, and the hot air discharged from the second air outlet also absorbs a large amount of heat. In other words, the hot air discharged from the second air outlet also carries away a large amount of heat, and the heat dissipation effect of the second air outlet is good, which is beneficial to reduce the temperature rise of the door body.

[0031] The application also provides a cooking equipment including the door body.

[0032] The cooking equipment has at least the following beneficial effects:

[0033] The direction of the natural flow of the hot air is upward, and the higher the position of the air, the more heat the air absorbs, and the higher the position of the air from which the hot air is discharged, the more heat the hot air carries away. In the door body of the cooking device, the first air outlets are all located at the upper position, and the hot air discharged from each of the first air outlets absorbs more heat, in other words, the hot air discharged from each of the first air outlets carries away more heat. Therefore, the heat dissipation effect of each of the first air outlets is good, which makes the heat dissipation performance of the door body good, and can effectively reduce the temperature rise of the door body.
