Abstract

PURPOSE:To make it possible to thaw a frozen food almost uniformly with high frequency waves, by means of a metallic member for preventing the transmission of electric waves provided on a table consisting of a netlike member for transmitting the electric waves. CONSTITUTION:A metallic member 3 for preventing the transmission of electric waves is provided on the peripheral part of a table 2, having plural legs 1, and consisting of a netlike member for transmitting the electric waves. Thus, the high frequency waves supplied from the bottom of the table 2 to the peripheral part of a material to be heated can be suppressed, and particularly the whole frozen food can be almost uniformly thawed without concentrating the high frequency waves around the peripheral part of the material to be heated.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heating cooking appliance used when thawing frozen foods using high frequency waves.

Structure of the conventional example and its problems Conventionally, as shown in FIG. 4, in this type of heating cooking appliance, the plurality of legs 1 and the rope section 2 provided at the bottom were entirely constructed on the radio wave transparent side. When frozen foods are thawed using high frequency waves, the high frequency waves reflected by the side walls 6 and bottom wall of the heating chamber are absorbed more in the periphery of the frozen foods 6 than in other areas, which causes uneven thawing. Ta.

OBJECT OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and provides a power i that can uniformly thaw frozen foods using high frequency.
The purpose is to provide heat cooking utensils.

Structure of the Invention In order to achieve the above object, the heating cooking appliance of the present invention has a structure in which a metal member for preventing transmission of radio waves is provided on the peripheral edge of a mounting table having a plurality of legs and made of a net-like radio wave transparent member. This has the effect that the entire frozen food can be thawed almost uniformly by suppressing the high frequency waves absorbed into the frozen food from the periphery and lower edge of the mounting table using the metal member.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In FIG. 1, 1 is a leg constituting a mounting table, and 2 is a rope. 3 is located on the rope section 2.

This is a metal member provided on the periphery of the rope portion 2 to prevent radio wave transmission. In the figure, the metal member 3 is provided on the lower surface of the rope portion 2, but it may also be buried within the rope portion 2.

Figure 2 shows the metal part 3 provided on the rope part 2, where a is a band-shaped metal plate, b is a band-shaped metal plate with numerous holes 4 with a diameter of 3 mm or less, and C is the spacing between the metal bars. It is a metal member with a thickness of 3 to 6 mm or less.

The functions and effects of the above configuration will be explained below based on FIG. 3.

A heating cooking utensil is housed in a heating chamber, a frozen food 5 is placed on the heating cooking utensil, and when high frequency waves from a high frequency oscillator are supplied into the heating chamber, the high frequencies are absorbed by the frozen food 6 as shown by the arrow. As is clear from FIG. 3, the high frequency waves that are reflected by the bottom wall 6 of the heating chamber and are about to be absorbed by the periphery of the frozen food 5 are reflected again by the metal member 3, and the radio waves are not absorbed by the periphery of the frozen food 6. It can prevent you from concentrating. Therefore, the entire frozen food 6 can be thawed almost uniformly without being thawed earlier than other parts or over-thawed.

Effects of the Invention As described above, according to the heating cooking appliance of the present invention, the metal part for preventing transmission of radio waves is provided on the peripheral edge of the mounting table made of a net-like structure for preventing transmission of radio waves. Since the high frequency waves supplied to the periphery of the heated object can be suppressed by the metal member, the high frequency waves will not be concentrated on the periphery of the heated object, and especially frozen foods can be thawed almost uniformly throughout. You can get the effect that you can.
