Abstract

(57) [Summary] [Problem] To make frozen gyoza etc. crisp and fragrant with only high-frequency energy without being watery. For this purpose, a receiving rod (8) made of a material having a relatively high electric resistance such as nickel chrome is provided in a heating chamber (2).
, And a food placing net 6 composed of an outer peripheral frame 7 is installed, and the net portion is supported by legs 9a, 9b, 9c formed integrally with the outer peripheral frame 7 using the wire material of the outer peripheral frame 7. I did it. At this time, each leg 9a, 9b, 9c is connected to a part of the receiving rod, for example, the leg 9a is connected to the receiving rod 8a, 8a to form a closed loop having a relatively long line length including the leg 9a. The heat generated in each loop was increased compared to the others. By causing the food placement net to generate heat by high-frequency current during high-frequency heating, food placed on a closed loop is particularly heated by high-frequency energy and heat generated from the food placement net.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-frequency heating cooker for cooking food by placing the food on a food placement net in a heating chamber.

[0002]

2. Description of the Related Art Conventionally, for example, heating using high-frequency energy has been performed to make frozen gyoza quickly edible. However, there is a problem that even if it becomes edible, the surface does not remain fragrant until it is watery.

[0003] In order to improve such a situation, heating using infrared energy or hot wind energy in addition to high frequency energy has been performed.

[0004]

If infrared or hot air energy is used in addition to high frequency energy, it takes a considerable time for the electric heater to start operating and reach the rated infrared radiation amount or the rated hot air temperature. Because of the necessity, there is a problem that the advantage of high-frequency heating cannot be fully utilized.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and in a heating cooker to which high-frequency energy is supplied into a heating chamber, the electric resistance of nickel chrome or the like is compared in the heating chamber. A food placement net made of high quality material is installed, and this food placement net is composed of receiving rods arranged in parallel with each other, an outer peripheral frame that fixedly connects them at the outer periphery, and legs that are integral with the outer peripheral frame. In addition, each leg is connected to each of the two receiving rods in the outer peripheral frame portion to form a closed loop having a relatively long line length, and the food placing net is heated by high-frequency current during high-frequency heating. A heating cooker wherein the food on the food placement net is heated by high frequency energy and heat generated from the food placement net.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The high-frequency heating cooker according to the present invention is as described above. At the time of high-frequency heating, a high-frequency current flows through the net-like food placement net and the placement net itself generates heat. The above food is heated not only by high frequency energy but also by conduction heat energy from the mounting net. Moreover, by connecting to the legs, the heat generated in the closed loop portion with a relatively long line length becomes vigorous, and the food placed in that portion will be actively heated by the receiving rod, and the conventional high frequency energy If only it was heated, it would have become watery finish,
It came to be fragrant in Paris.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1, reference numeral 1 denotes a high-frequency heating device main body, 2 denotes a heating chamber, and 3 denotes a door for opening and closing the heating chamber 2. Reference numeral 3 denotes a connection port for connecting a high-frequency oscillator (not shown) to the heating chamber 2, reference numeral 5 denotes a dielectric tray placed on the bottom of the heating chamber, and reference numeral 6 denotes a wire formed circularly on the tray 5. The set food placing net 7 is an outer peripheral frame constituting the outermost peripheral portion of the food placing net 6, and 8, 8,.
A plurality of receiving rods 9a, 9b, and 9c are attached inside each other, and a wire rod used for an outer frame is used to position the placement net 6 at a predetermined height on the receiving tray 5. Three legs formed.

The mounting net 6 has a wire diameter of the outer peripheral frame 7 and the legs 9a, 9b, 9c of 3.0 mm, receiving rods 8, 8,
8, wire diameter: 2.5mm, height of legs 9a, 9b, 9c: about 90mm, which is three quarters of the wavelength of high-frequency radio waves, and nickel chromium material with high electrical resistance for all parts Made of.

Next, FIGS. 3 and 4 are views of the food placing net 6 as viewed from the top and side, respectively. As shown in these figures, each leg has, for example, 9a a receiving rod 8a at the center. ,
8a to form a closed loop, and the leg 9b is connected to the receiving rods 8b and 8b at the right end of FIG. 3 to form a closed loop having a slightly smaller scale than the central closed loop, that is, a shorter line length. Also, at the left end of FIG.
Are connected to the receiving rods 8c, 8c to form a closed loop of the same size as the closed loop at the right end. As a result, more current flows through each of these loops of the food placing net 6 during exposure to high-frequency radio waves than in other loops not connected to the legs 9a, 9b, 9c, and vigorous heat generation occurs. Is being done. Arrows in FIG. 3 and FIG. 4 indicate high-frequency currents.

Reference numerals 10, 10, 10,... Denote frozen gyozas placed on the placement net 6 particularly along each of the loops described above.

In the above-described apparatus, when the high-frequency heating is started, the gyoza 10, 10, 10,.
..At the same time as the temperature gradually rises, the receiving rods 8, 8,
.. Also cause a rise in temperature due to the high-frequency current, and the gyoza is also heated by the heat generated. In particular, since the receiving rods 8a, 8a, 8b, 8b, 8c, 8c which are connected to the legs 9a, 9b, 9c to form a closed loop generate a great deal of heat, the gyozas 10, 10,
The lower surfaces of 10,... Are heated to such an extent that they are scorched by the heat.

[0013] As a result, what has conventionally tended to be watery only with high-frequency heating has become a crisp and fragrant finish without wateriness.

In the above description, an example in which the placing net 6 is fixedly set in the heating chamber 2 is taken up, but it may be installed on a turntable and rotated. Also, regardless of the wire,
It may be made by punching a plate material.

Further, the material of the legs may be made of a material having a small electric resistance such as simple carbon steel, instead of the material used for the receiving rod and the outer peripheral frame. In that case, an effect is obtained that wasteful heat generation at the leg portion is reduced.

[0016] Also, in the part of the receiving rod that is not actively generating heat,
If a material having a higher electric resistance value is used, or if the wire diameter is reduced even if the resistance value is the same, it is expected that the unevenness of the burn will be reduced.

[0017]

As described above, according to the present invention, the heat generated by the food placing net made of a metal material having a large electric resistance is used, although the heating is performed only by the high frequency energy from the high frequency oscillator. In particular, frozen gyoza and the like placed on a receiving rod that has formed a closed loop having a relatively long line length by connecting the legs and the receiving rod,
It never ceased to be watery, and it became crisp and fragrant.

Further, unlike the one in which the radio wave absorbing heating material is applied, the food placing net can be made of a simple solid material, so that there is no problem of performance deterioration due to peeling off of the radio wave absorbing material.
