Heating cooker

Abstract

The invention relates to a heating cooker. When detecting indoor temperature and heating to cook, the temperature can be controlled more nicely in a wide temperature range from a lower temperature to a higher temperature. An indoor temperature detecting element for detecting temperature in a cooking chamber (1) is provided first and second thermistors (26, 27) having different detecting temperature characteristics. When supplying steam to the chamber by a steam feeding device (10) as in the condition of high temperature steam cooking with the given temperature not less than 100 DEG C, the steam feeding device (10) and hot-blast heaters (2, 3) are controlled by the detecting temperature of the second thermistor (27) with excellent detection precision at high temperature. In the condition of low temperature steam cooking with the given temperature less than 100 DEG C (such as 40 DEG C), the steam feeding device (10) and hot-blast heaters (2, 3) are controlled by the detecting temperature of the first thermistor (26) with excellent detection precision at low temperature.

Description

heating cooker technical field The present invention relates to a heating cooker with such a structure that an indoor heating unit and a steam supply unit are controlled based on the detected temperature of an indoor temperature detecting element for detecting the temperature inside a cooking chamber (cabinet). Background technique In heating cookers, in addition to heating cooking using heating members such as electric heaters and magnetrons, methods that allow heating cooking using steam have been proposed (for example, refer to Patent Document 1). In this case, it is installed to detect the temperature in the cooking chamber (heating chamber) with an indoor temperature detection element including a thermistor, and to control the electric heater for indoor heating and the steam supply part so that the indoor becomes the set temperature. composition of temperature. [Patent Document 1] JP-A-2005-308315 However, in this heating cooker, there are cases where the indoor t...

Problems solved by technology

If a single indoor temperature detection element is used to detect and control a relatively low temperature from 40 to 50°C to a relatively high temperature of 200°C or higher, the detection error will be large, and there is a problem that high-precision temperature control cannot be performed.
