摘要:
A heating and cooking apparatus has a detection sensor for sensing the state of heating so as to automatically control the heating operation. A partition is disposed so as to be opened to the inside of an auxiliary passage which has an inlet located at a position in the vicinity of the circumference of an impeller of a cooling fan for cooling a magnetron provided on the back side of a heating chamber and through which steam from the heating chamber is discharged to the outside. Air supplied by the fan is blown off into the auxiliary passage so as to generate a venturi action, thus promoting the flow of steam in the auxiliary passage. The detection sensor is disposed in the auxiliary passage at a position in the vicinity of a region where air is blown off so as to accurately sense the state of steam generated from a material to be heated.

A pyroelectric sensing apparatus is provided with an A/D convertor 29, whose digital output is examined whether continuation time period of the output from the pyroelectric element is longer than a predetermined reference time period such as 500 m sec; thereby mal-operation due to noise output from the pyroelectric element generated by mechanical shock (door close) or electric shock (pulling out a plug of other apparatus) is eliminated.
摘要:
An antenna (6) for sensing a portion of electromagnetic waves irradiated into a heating chamber by a wave irradiator (3) and a detection circuit for performing detection of electric power from the output of the antenna are provided on the same printed board (11), while operation of devices is controlled by a controller (8) on the basis of an output of the detection circuit such that an optimum finished state of cooking is obtained.
摘要:
A high frequency heating apparatus and an electromagnetic wave detector for use in the high frequency heating apparatus, are so arranged to estimate the cooking or thawing state of a food article placed in a heating chamber through detection of microwaves within the heating chamber. By devising a position of an antenna and a method of processing signals of the microwaves as detected, stably and reliable microwave detection becomes possible.
摘要:
A high frequency heating apparatus for heating an object to be heated is provided with an electromagnetic wave emission device for emitting electromagnetic waves, a local heating device capable of heating an optional portion of the object by the electromagnetic waves emitted from the emission device, and a control device for controlling the local heating device. The high frequency heating apparatus is further provided with a stage on which the object is placed, a protecting device for protecting the local heating device, a setting device and a detection device, so that the local heating device, the electromagnetic wave emission device or the stage is controlled in accordance with the setting device or the detection device.
摘要:
A high-frequency heating apparatus includes: a high-frequency oscillator for generating high-frequency electromagnetic waves using electrical power supplied from a power source circuit; a heating chamber into which the high-frequency electromagnetic waves are supplied by the high-frequency oscillator; a receiving antenna which is provided outside the heating chamber and adjacent to an opening of the heating chamber; a dielectric plate for covering the opening, which is provided between the heating chamber and the antenna; and a control circuit which receives an output from the antenna via a detector so as to output a control signal to the power source circuit.
摘要:
A cooking appliance performs cooking which is remotely controlled, based on information relating to the object to be heated, as the information is transmitted to the appliance's computer from a management's computer. The cooking appliance can also cook any part of food in the cooking chamber locally.
