Problems solved by technology

Therefore, it is difficult to obtain a suitable mixed state of hot air, and it is impossible to obtain uneven hot air circulation and uniform heating distribution in the box.
[0011] And in the heating cooker that has steam supply mechanism, the situation that steam adheres to the wall surface of the oven casing and becomes water drop is in the majority, especially, if produce water drop on the top surface surface of oven casing, then water drop falls from top surface, and adheres to In food, may affect cooking results
In this case, in the heating cooker of the above-mentioned Patent Document 2, although countermeasures have been considered for the recovery of the water droplets on the back panel of the oven box, it is not possible to prevent the water droplets from falling on the food from the top surface.
In addition, although the structure described in Patent Document 3 is effective in preventing fogging or dew condensation on the see-through window of the door, it cannot prevent water droplets from falling on the food from the top surface.

Abstract

The present invention provides a heating cooking device, the hot air blown from a hot air circling unit can be evenly circled in a oven body and seek to equalization heating distribution. In order toheat the food contained in the oven body (2) by the hot air oven, the heating cooking device has a hot air circling unit comprising a hot air heater (7) and a hot air fan (6), wherein a curve shape portion (S) having a depressed inner side is arranged at least one of peripheral surface of the peripheral surfaces of the oven body (2) blowing hot air from the hot air circling unit.

Description

technical field [0001] The present invention relates to a heating cooker capable of cooking food by heating in a hot air oven. Background technique [0002] Conventionally, in order to broaden the types of heating and cooking of foods, heating cookers having a plurality of heating mechanisms have been provided. For example, a heating mechanism including a hot air circulation unit for heating food in a hot air oven, a magnetron (magnetron) for microwave (high frequency) heating of food, and a flat heater for baking and cooking is widely popularized. cooker. [0003] Wherein, the above-mentioned hot air circulation unit is used as a heating mechanism, for example, is arranged on the peripheral wall side of the innermost part of the oven box, is configured to include a hot air heater and a hot air fan, and repeats the following cycle: from the hot air circulation unit to the oven box. The hot air blown out is recycled to the hot air circulation unit after heating the food pla...
