Abstract: A high-frequency heating apparatus includes: a heating chamber for accommodating a load; a microwave source; at least one radiator; a temperature detector; and a controller. The microwave source generates a microwave and adjusts the frequency and output of the microwave. The at least one radiator radiates a microwave into the heating chamber. The temperature detector detects the temperature in the heating chamber. The controller causes the microwave source to adjust the output of the microwave based on the temperature profile that defines the temperature change in the load, and the temperature in the heating chamber. According to this aspect, food can be heated in accordance with the temperature profile appropriate for the cooking recipe, thereby ensuring the quality of cooked food.

Abstract: The heating cooker includes a first heater disposed below a tray to heat the tray, and second heater disposed over the tray to heat the tray. In addition, the heating cooker includes a controller that controls output of the first heater and switches energization of second heater in accordance with a kind of object to be heated and a quantity of object to be heated. Furthermore, second heater includes two plane-shaped insulators and a plurality of planar heat generators that are sandwiched between insulators, and the controller heats regions that are disposed over and below the tray to be opposed to each other by controlling energization of the first heater and second heater. Furthermore, second heater has a distortion suppressor between the plurality of planar heat generators, and the distortion suppressor suppresses internal distortion of insulators caused by heating of the plurality of planar heat generators of second heater.

Abstract: In order to radiate microwaves from a waveguide tube to a whole area from end to end of a radiation area within a heating chamber, and to heat uniformly an object to be heated without using a driving mechanism, a microwave heating device of the present invention includes openings for radiating the microwave from the waveguide tube to the inside of the heating chamber. The heating chamber includes a radiation area which has a length of approximate twice an in-tube wavelength in a propagation direction of the waveguide tube. Also, the openings are arranged to have an interval of approximate the in-tube wavelength in the propagation direction of the waveguide tube, and are symmetrically arranged to a center line which intersects perpendicularly to the propagation direction in the radiation area.
