Cooking liner structure and oven with same

Abstract

The invention relates to a cooking inner container structure and an oven with same. The structure comprises an inner container, a hot air baffle with an air inlet and an air outlet is arranged on the rear side of an inner cavity of the inner container, a hot air chamber is defined by the hot air baffle and a back plate of the inner container, an air heater is installed in the hot air chamber, heating pipes are arranged on the peripheries of fan blades of the air heater, the air inlet area of the air inlet is larger than the total air outlet area of the air outlet, the air outlet comprises a first air outlet located in the upper left portion of the hot air baffle and a second air outlet located in the lower right portion of the hot air baffle, the sum of the air outlet amount of the first air outlet and the air outlet amount of the second air outlet is larger than 50% of the total air outlet amount of the air outlet, and the air outlet amount of the first air outlet is larger than that of the second air outlet. The air inlet amount of the hot air chamber can be increased, then the air outlet amount needed by cooking is met, the cooking heat needed by the inner container is met on the basis that only one heating pipe is arranged, the uniformity of a temperature field in the inner container can be promoted, and then the cooking effect of the inner container is improved. In addition, the cooking efficiency and the cooking effect can be improved.

Description

technical field [0001] The invention relates to the field of cooking devices, in particular to a cooking liner structure and an oven with the structure. Background technique [0002] A hot air baffle is generally arranged in the inner tank of cooking devices with baking functions such as an oven. The hot air baffle has an air inlet and an air outlet, and the back plate of the inner tank and the hot air baffle form a hot air chamber. A hot air blower and a heating pipe are respectively arranged in the middle, and the shape of the heating pipe is circular and is arranged around the outer periphery of the fan blade of the hot air blower. In this way, the hot air blower rotates in the hot air chamber to generate negative pressure, and the airflow in the inner tank enters the hot air chamber under the effect of negative pressure to be heated, and the heated hot air flows from the hot air baffle under the action of the centrifugal force of the hot air blower. The air outlet retur...

AI Technical Summary

Problems solved by technology

[0003] The inner tank of the traditional oven is equipped with an upper heating tube, a middle heating tube and a lower heating tube respectively. The heating tube in the above-mentioned hot air chamber is a middle heating tube, and three heating tubes are installed at the same time, which makes the production cost of the traditional oven higher.

In addition, the area of ​​the air inlet and air outlet of the existing hot air baffle is relatively large, and the speed of the hot air blower is fixed at the same time, resulting in a small air volume of the inner tank during the baking process of the existing oven, and because the air volume is not adjustable, the baking When the food needs a large air volume, the expected cooking effect cannot be achieved
