Problems solved by technology

However, in the case of thawing frozen food with a microwave oven, it can be thawed in a short time, but sometimes the high-frequency energy is concentrated on the previously thawed part and cannot be thawed uniformly, that is, "partially cooked". Thawed state of
In this way, when thawing frozen food using a microwave oven, it is difficult to obtain the desired high-quality thawed state.

Embodiment approach 1

[0058] Hereinafter, Embodiment 1 of the refrigerator including the heating device of the present invention will be described with reference to the drawings. figure 1 It is a figure which shows the vertical cross-section of the refrigerator 10 which concerns on Embodiment 1. figure 1 Among them, the left side is the front side of refrigerator 10 , and the right side is the back side of refrigerator 10 . The refrigerator 10 is composed of an outer box 1 mainly formed of a steel plate, an inner box 2 formed of resin such as ABS, and a space between the outer box 1 and the inner box 2 filled with a foamed heat insulating material (for example, rigid polyurethane foam). 40 to form a thermal insulation box.

[0059] The heat-insulated box of refrigerator 10 includes a plurality of storage rooms, and an openable and closable door is arranged on the front side opening of each storage room. Each storage room is sealed so that cold air will not leak through the closing of the door. I...

Embodiment approach 2

[0117] Hereinafter, a refrigerator according to Embodiment 2 of the present invention will be described with reference to the drawings. The refrigerator according to Embodiment 2 has a structure incorporating a heating device. The heating device incorporated in the refrigerator according to Embodiment 2 is constituted by a high-frequency heating device having a structure in which freezing / thawing chamber 5 is constructed in refrigerator 10 according to Embodiment 1 described above. In the heating device of Embodiment 2, the same structure as the electrode structure, electrode holding mechanism, and electromagnetic wave shielding mechanism in Embodiment 1 can be used, but as the present invention, the same structure can be realized even if the structure described in Embodiment 2 is used. Effect. In addition, other configurations of the refrigerator incorporating the heating device according to Embodiment 2 are the same as those of refrigerator 10 according to Embodiment 1. As ...

Abstract

The present invention provides a highly reliable and very safe heating device which is capable of uniformly heating an object to be heated, and a refrigerator equipped with a storage space capable of easily thawing / freezing a frozen item in a high-quality state as a stored item. This heating device is equipped with: an oscillating electrode which is provided in one heating space for storing an object to be heated and has an electrode surface on which an electric field concentration region is formed; a counter electrode which is provided in another heating space and has an electrode surface which faces the electrode surface of the oscillating electrode; and a high-frequency electric field-forming section for forming a high-frequency electric field to be applied between the oscillating electrode and the counter electrode.

Description

technical field [0001] The present invention relates to a heating device having a heating chamber capable of thawing frozen products and a refrigerator provided with the heating device. Background technique [0002] A general refrigerator includes a freezer for freezing ingredients and foods and storing them as frozen products for a long period of time. It is desirable to thaw such a frozen product in a short time and use it for cooking in a thawed state as close to a fresh state as possible. [0003] In order to thaw frozen products, there are thawing treatments such as natural thawing at room temperature or running water thawing using tap water, but these thawing treatments do not meet the short-term thawing required by cooks. In general households, in order to thaw frozen products in a short period of time, microwave heating cookers, namely microwave ovens, are used. However, in the case of thawing frozen food with a microwave oven, it can be thawed in a short time, but...
