Steam cooker and steam generator
First Claim
1. A steam generator, comprising:
- a pot to which water is supplied;
a heater placed in the pot;
a water level sensor that detects a level of the water contained in the pot;
a temperature sensor that detects a temperature inside the pot; and
a controller that controls an amount of water in the pot based on an output from the water level sensor and an output from the temperature sensor so as to maintain the heater submerged in the water,wherein the water level sensor is a self-heating thermistor, andwherein the controller judges whether the heater is submerged in the water or not by obtaining a reference value based on the output from the temperature sensor and comparing the output from the water level sensor with the reference value.

Abstract
A steam cooker includes a steam generator for generating steam, a steam temperature-raising device for raising a temperature of steam coming from the steam generator, and a heating chamber in which an object to be cooked is heated by steam supplied from the steam temperature-raising device. The steam generator has a pot (41) to which water is supplied, a heater (42) placed in the pot (41), a water level sensor (43) and a temperature sensor (48) placed in the pot (41). The water level sensor (43) and the temperature sensor (48) are placed at opposed side surfaces in the pot (41) that correspond to the short sides of an elongated roughly rectangular planar shape of the pot (41). An exposed state of the heater (42) from the water in the pot (41) is judged by the water level sensor (43) and the temperature sensor (48).
