A high-frequency heating apparatus of the present invention includes a heating chamber to which a heating plate for loading a subject to be heated thereon is detachably attached, a microwave generating unit, a waveguide for transmitting a microwave from the microwave generating unit, a rotation antenna for radiating the microwave into the heating chamber from the waveguide, a driving unit for turning/driving the rotation antenna, an operating portion capable of choosing the grill menu by which the subject to be heated put on the heating plate is heated and a hot-up menu by which the subject to be heated is heated without the heating plate, and a controlling unit for controlling the driving unit based on an output signal form the operating portion, wherein the controlling unit controls to vary a direction of a sharp portion of a radiation directivity of the rotation antenna in response to the output signal from the operating portion.

Microwave heating apparatus

A high frequency heating apparatus having a steam generating function including a heater main bodyembedded with heater, a transport tube heating portionfor boiling a liquid in a transport tube, and a heat conduction control portioncomprising a material having a heat conductivity smaller than a heat conductivity of a material forming an evaporating portionand capable of restraining adherence of scale in accordance with local boiling in the transport tube by reducing an amount of heat conducted to the transport tubewhile ensuring heat energy supplied to an evaporating side by setting heater to a high temperature. Further, a steam supply mechanism for excellently maintaining a balance of supply of the heat energy to a side of a transport portion and a side of an evaporating portion and continuously generating steam at a high temperature near to 100&#xb0; C. can be provided.

High frequency heating apparatus having steam generating function

An object of the present invention is to provide a high frequency heating apparatus having a steam generating function in which a time required for evaporation of dropped water can be remarkably increased when water is dropped onto an evaporation tray and the heating efficiency is high. The high frequency heating apparatus has a steam generating function that includes a high frequency generator and a steam generator that includes an evaporation tray provided on the bottom surface of a heating chamber in which a heating target is mounted and a heater device for heating the evaporation tray to generate steam in the heating chamber, wherein the heater device is constructed as a heater device () having a sheathed heater () embedded in an aluminum die cast (), and the heater device is directly attached to the back side of the evaporation tray ().
