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.

A compact and highly controllable impedance-varying-unit, a microwave device using the same unit, and a high-frequency-heating appliance using the same unit are provided. The impedance varying unit includes a rectangular waveguide-section as a main body made of metallic material, an open end of waveguide-section working on microwave in a microwave cavity, a terminal end of waveguide-section closed by metallic material, a rotary movable body made of non-metallic material, and a driver for the movable body. A rotating angle or a position of the movable body is controlled, so that an impedance at the open end is varied and transmission status of microwave is changed, thereby variably controlling a standing wave distribution. Controlling the standing wave distribution allows an object in the cavity to be selectively heated or uniformly heated. Further, the standing wave produced in the microwave cavity is sequentially varied, so that the object can be selectively heated or uniformly heated. The present invention solves the problem of spark production, and provides a compact as well as highly controllable impedance varying unit, a microwave device using the same unit and a high-frequency-heating appliance using the same unit.

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 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.
