Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a door body, a cooking device and a cooking center. Background Art

[0002] With the development of technology, the integration of various kitchen appliances has become a norm. At present, the main integration of range hoods and steam ovens is in floor-standing integrated cooktops. Due to the relatively low installation height of floor-standing integrated cooktops, the operating table space restricts the range hood, and the performance of the range hood is often lower than that of traditional range hoods. For users who like stir-frying, there are often weaknesses in performance. Therefore, wall-mounted integrated cooking centers have been developed. The range hood and the steam oven are integrated in the wall-mounted cooking center. The range hood has a large installation space, so the performance of the range hood is excellent. However, the door of the steam oven in the wall-mounted integrated cooking center is located above the cooking stove, and the ordinary door body of the steam oven cannot achieve a good heat dissipation effect.

[0003] Therefore, there is an urgent need for a door body to solve the above problems. Summary of the Utility Model

A first air inlet hole 301 is opened on the first end of the upper part of the door frame 1, and a first air outlet hole 402 is opened on the second end of the upper part of the door frame 1. Both the first air inlet hole 301 and the first air outlet hole 402 are communicated with the heat dissipation air duct 100. The first end of the upper part of the door frame 1 and the second end of the upper part of the door frame 1 are arranged opposite to each other. The panel assembly includes a front panel 21 and a rear panel 23 both installed on the door frame 1. The front panel 21 and the rear panel 23 are arranged at intervals and enclose a heat dissipation cavity 200 with the door frame 1. The heat dissipation cavity 200 is located inside the heat dissipation air duct 100. A first heat dissipation hole structure communicating the heat dissipation air duct 100 with the heat dissipation cavity 200 is opened on the side wall of the lower part of the heat dissipation cavity 200, and a second heat dissipation hole structure communicating the heat dissipation air duct 100 with the heat dissipation cavity 200 is opened on the side wall of the upper part of the heat dissipation cavity 200. The second heat dissipation hole structure is located at the second end of the door frame 1. Cold air enters the heat dissipation air duct 100 from the first air inlet hole 301, flows from the upper part to the lower part of the door body 101 along the heat dissipation air duct 100, then enters the heat dissipation cavity 200 through the first heat dissipation hole structure, and then flows out to the heat dissipation air duct 100 through the second heat dissipation hole structure, so that the hot air in the door body 101 finally flows out of the door body 101 through the first air outlet hole 402, thereby realizing heat dissipation and temperature reduction of the door body 101. By opening the first air inlet hole 301 and the first air outlet hole 402 on the upper part of the door frame 1, when the cooking device 10 is installed in the cooking center above the cooking range, the first air inlet hole 301 and the first air outlet hole 402 can avoid the smoke flowing upward during cooking, thereby preventing the smoke from entering the door body 101, causing the temperature inside the door body 101 to rise, making it difficult for the door body 101 to achieve temperature reduction, and at the same time, preventing the smoke from causing dirt inside the door body 101.
