A microwave heating apparatus includes a heating chamber,for accommodating an item,to be heated; a microwave generator,for radiating microwaves to the heating chamber,and a vapor generator,for supplying vapor to the heating chamber,. The heating chamber,includes regenerating plates,and,for generating and regenerating heat when radiated by the microwaves from the microwave generator,thereby reducing dew condensation caused by the vapor in the heating chamber

Microwave heating apparatus with a vapor generator and regenerating plates

A pressure cooker with a humidity sensor or gas sensor, wherein a micro-computer reliably detects the point at which the internal pressure of a pressure cavity reaches a prescribed value by using this sensor by detecting the point at which a pressure control valve begins to operate and begins to discharge a large quantity of excess vapor or gas etc. from the pressure cavity to the outside, with a result which is equivalent to that of a direct measurement of the internal pressure with a pressure sensor, thereby attaining an accurate measurement without bringing the humidity or gas sensor into contact with the pressure cavity.

A safety device for a heating apparatus detects the errors of the input power-supply voltage, failures of the respective heating device and control device, and displays the detected failure and safety stops the associated apparatus. The safety device quickly and safely stops only a faulty heating function if the heating apparatus further has a plurality of heating functions, and allows the other normal heating functions of the heating apparatus to be used.

Controlling device for electric apparatus

A high frequency heating apparatus includes an inverter controlling circuit for controlling a semiconductor portion for feeding a low voltage power supply switching element, a low voltage power supply to the controlling circuit, an operation switch for activating the apparatus by a user, and a system controlling portion for controlling a load switching device. The load switching device is adapted to switch on and off at least one of the low voltage power supply leading to the inverter controlling circuit and a rectification circuit.

High-frequency heating apparatus

In a key input device, the depression of any one of the keys of a keyboard applies a voltage to an analog-digital conversion input terminal and to one of a plurality of ordinary input terminals so that in accordance with the resulting analog-digital input terminal voltage and ordinary input terminal voltage, a microcomputer discriminates the depressed key.

Key input device

An improved high frequency heating apparatus of a type having a drawer-type door assembly together with a turn-table driven from the exterior of a heating chamber and also a support shelf therefor, which is so arranged that the stroke of the door assembly for closing and opening may be set irrespective of depth of the heating chamber, with the positional relation between the turn-table and bottom wall of the heating chamber being accurately maintained during driving of the turn-table.

High frequency oven with drawer type door

A cooking device with one cooking or heating chamber in which food may be heated by either one or both of high-frequency heating means and the resistance heating means. The high-frequency or microwave energy is radiated into the heating chamber from the top while the air heated to high temperatures by the resistance heating means disposed within a rear chamber defined back of the rear wall of the heating chamber is circulated therethrough by a circulation fan. Food charges are placed on a receptacle which in turn is placed on a turntable, whereby the food charges may be uniformly heated. The simultaneous use of both the high frequency heating means and the resistance heating means may enable a more wide variety of food to be cooked by a more wide variety of methods.
