Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating cooker having a high-frequency generator that radiates high-frequency waves in a heating chamber and a heater device that raises the ambient temperature, and a so-called rotating object to be heated in the heating chamber. The present invention relates to a heating cooker with a turntable.

2. Description of the Related Art In the conventional cooking device shown in FIGS. 5 and 6, for example, a heating chamber 2 is provided inside a main body 1, and a door 3 is provided in front of the heating chamber.
There is a turntable 4 at the bottom. The turntable 4 is rotated by a turntable motor b via a shaft 5, and a choke 7 for preventing electric wave leakage, a heat insulating plate 8 and the like are attached. In the rear part of the heating chamber 2, the combustion gas heated by the gas burner 9 is sent into the heating chamber 2 by the circulation fan 10,
The accumulated air is discharged to the outside through the exhaust guide 11. On the side of the heating chamber 2, a magnetron 13, a transformer 14, a fan motor 15 and the like that radiate a high frequency through the waveguide 12 are installed in the heating chamber 2.

The problem to be solved by the invention However, in such a heating cooker, the heating chamber is generally covered with a holo film, but the choke 7 part for preventing radio wave leakage has been a problem. It is difficult for the cleaning solution to be washed with the cleaning solution before the holo coating to come out from the chalk portion, and the remaining cleaning solution causes the holo coating to fail to form rust.
Further, there was a problem that the holo solution was difficult to enter and difficult to come out during the holo coating.

The present invention solves such conventional problems, and an object of the present invention is to provide a heating cooker having a stable quality by performing holo coating with good workability.

Means for Solving the Problems In order to achieve the above object, the heating cooker of the present invention forms a choke by welding a pan-shaped metal plate having a large number of holes in the peripheral wall to the outer bottom wall of the heating chamber. An enclosure is inserted on the outer side of a pot-shaped metal plate, and the enclosure is sandwiched between the heating chamber bottom wall and a heat insulating plate.

Effect In the heating chamber of the heating cooker of the present invention, the cleaning liquid and the holo solution are easily put in and out during the holo coating, the workability and quality are improved, and hot air does not leak from the holes provided in the peripheral wall of the choke part. It has an effect that a stable product can be provided without a temperature rise.

Embodiment Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

Differences from the conventional example will be described with reference to FIGS. 1 to 4.
The choke 7 for preventing electric wave leakage is welded to the outer bottom of the heating chamber by making a large number of holes 16 in the peripheral wall of the pan-shaped metal plate 7 as shown in FIG. When such a hole is opened, both the cleaning solution and the holo solution can easily come in and out during the holo film, and a holo film that is completely adhered can be obtained. An enclosure 17 shown in FIG. 4 is inserted on the outside of the choke 7, and the enclosure 17 is sandwiched and fixed between the bottom wall of the heating chamber 2 and the heat insulating plate 8. The enclosure 17 may be ring-shaped, square-shaped, or any heat-resistant material, but the ring-shaped metal plate is the simplest. When a metal material is used, a bent portion 18 is provided at the end as shown in FIG.

Although the above is described for the gas heating device, the same applies to the electric heating device.

Effects of the Invention As described above, according to the heating cooker of the present invention, the following effects can be obtained.

(1) During the holo-coating, the cleaning solution and holo-solution can be easily taken in and out, and a complete holo-coating can be obtained. The bottom wall of the heating chamber is a place where spills during cooking and water during cleaning are most likely to come into contact, and once spilled into the chalk part, it cannot be wiped off once water enters, which is the most rusty place. The quality is stable.

(2) In the present invention, the enclosure prevents the hot air in the heating chamber from leaking from the hole provided in the choke portion, so that the thermal efficiency is good, and therefore the adverse effects such as the temperature rise of other components are adversely affected. Hard to reach. In particular, in the case of a hot-air circulation type heating cooker using a gas as a heat source as shown in FIG. 2, the pressure inside the heating chamber is high, so that hot air leak easily occurs, but in the present invention, only a simple enclosure is used. It is possible to prevent hot air leaks, workability is good, and it is economical.
