A refrigerator includes a cooling/heating chamber capable of cooling and heating foods. The cooling/heating chamber is divided into a heating zone that is a space where foods to be heated are placed, and a non-heating zone that is a space continuous with the heating zone where foods not to be heated are placed. The refrigerator further includes an oscillation electrode and a counter electrode that are arranged so as to face each other with the heating zone in between, and an oscillating unit that applies an AC voltage to between the oscillation electrode and the counter electrode.

The present invention provides a highly reliable and safe heating device that can uniformly heat an object to be heated and provides a refrigerator having a storage space in which frozen products as storage products can be easily thawed to a high-quality state. A heating device of the present invention includes an oscillation electrode disposed on one hand of the heating space and having an electrode surface on which an electric field concentration region is formed, a counter electrode disposed on the other hand of the heating space and having an electrode surface that faces the electrode surface of the oscillation electrode, and a high-frequency electric field forming unit for forming a high-frequency electric field applied to between the oscillation electrode and the counter electrode.

A high-frequency heating device that includes: a first conductor; a second conductor disposed with the first conductor through a space therebetween; a high-frequency power source that is connected to the first conductor and the second conductor and that applies a high-frequency voltage between the first conductor and the second conductor; and a connection path that electrically connects the first conductor and the second conductor to each other at a first connection position and a second connection position. The first connection position is different from a first power feeding position at which the first conductor and the high-frequency power source are connected to each other on the first conductor, and the second connection position is different from a second power feeding position at which the second conductor and the high-frequency power source are connected to each other on the second conductor.

Disclosed are a dielectric substance-electrode assembly in which an electrode is coated with a dielectric and a method for manufacturing the same. The dielectric substance-electrode assembly is formed by forming a lower dielectric electrode constituting a lower portion of an assembly body, sealing a capsule filled with a treated powder and a lower dielectric in which an electrode is formed, and forming an upper dielectric constituting an upper portion of the assembly body using the treated powder which is diffused on and bonded to surfaces of the lower dielectric and the electrode due to sintering heat treatment which is performed by applying an isostatic pressure in a state in which the sealed capsule is placed in a pressure vessel of a heat treatment equipment.

A lossy dielectric heat source transducer or other transducer can be formed using a multi-layer substrate, such as can include a power layer (to receive an applied electromagnetic input signal), a polyurethane or other polymeric electromagnetic energy absorption layer, and a coupling layer therebetween. The absorption layer can be doped with carbon or another dopant material to increase electromagnetic energy absorption. The coupling layer can be doped with barium titanate or another dopant material to focus electromagnetic energy passing through the coupling layer toward the absorption layer. Frequency-selective addressing of particular transducers can include using a plurality of planar resonators, which can be configured to resonate at the same or different specified frequencies of the applied electromagnetic input. Such addressing of such frequency-sensitive structures can permit location-specific actuation of one or more transducers.
