Abstract

PROBLEM TO BE SOLVED: To enable a heater with prompt light-emitting performance to have improved durability in use and to be composed with easiness of assembling in either use as a cooking device or a high-frequency heating device. SOLUTION: In a cooking device, a heating body 3 of a heater 2 for cooking a food material consists essentially of carbon material, and the heating body 3 is inserted into a glass tube 4, and the heater 2 having the glass tube 4 with enclosed inert gas is provided on an outside of a heating chamber 1, and a reflection plate 5 surrounding the heater 2 is provided. Consequently, quick kick-off of light-emitting performance of the heater 2 is maintained, and approximate wire temperature of 900 deg.C in heating use of the heater 2 renders light non-glare. In high-frequency use of the same, leakage of high-frequency into an inside of the reflection plate 5 covering the heater 2 is eliminated by punching holes 7 on a surface of the heating chamber 1 placed oppositely to the heater 2, rendering assembling components of the heater 2 and reflection plate 5 facile.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating cooker, and more particularly, to a heater configuration and a heater mounting configuration.

[0002]

2. Description of the Related Art A conventional heater of this type of heating cooker has been disclosed in Japanese Utility Model Laid-Open Publication No. 62-140689. As shown in FIG. 6, the heater 15 of the heating cooker (the light bulb main body in the figure) has a heater 15 inserted into a glass tube, both ends of which are sealed, and a halide in the glass tube. Are commonly called halogen lamp heaters (halogen heaters for short) and the like.

As shown in FIG. 7, another conventional high-frequency heating cooker has a heater 16 as described in Japanese Patent Application Laid-Open No. 2-279923. The mounting configuration of the heater of this heating cooker is the heating chamber 1
A square hole 20 is provided in the upper surface 18 of the heating chamber wall opposite to the heater 16 provided above the heater 7 and is covered with a reflecting plate 19 for reflecting the heat of the heater 16. That is, the heater 16 in the reflection plate 19 was configured to be exposed to a high frequency.

[0004]

However, FIG.
Although the conventional heating cooker has a good performance in which the heater 15 emits light quickly (a heater lamp emits light immediately after the power is turned on and can visually appeal to the user), the line temperature when the heater 15 generates heat is low. The temperature was about 2600 ° C, and there was a problem that it was dazzling and could not be seen directly. Therefore, the surface may be used by being colored red by a chemical reaction of sulfated copper. However, if the food debris scattered during cooking adheres and is repeatedly used, the repetition of the food debris and the like that adheres to the glass tube causes holes to be formed, and the heater 15 cannot be used. Even the problem that occurred.

On the other hand, in another conventional high frequency heating cooker of FIG. 7, the heater 16 in the reflector 19 is exposed to high frequency, so that the heater 1 penetrating through the reflector 19 is used.
6 is provided with a more complicated high-frequency seal 21 so that the high-frequency does not leak from both ends of the reflector 6. Even if it is desired to improve the assemblability due to the method of stacking and assembling the components, the reflecting plate 19 fixed to the heating chamber 17 can be improved. In order to penetrate the inside of the complicated high-frequency seal 21 so as not to break the heater 16, it takes a long time to assemble, and there is a problem that the assembling workability is poor.

[0006]

A plurality of punching holes are provided on the surface of the chamber.

By filling the glass tube with an inert gas, the durability of the heater during use is improved. In addition, while maintaining the fast rising light emission performance of the heater,
Since the line temperature at the time of using the heat generated by the heater is about 900 ° C., the glare can be eliminated. Further, since the glass tube is not dazzled, it is not necessary to color the glass tube scientifically red with copper sulfate or the like, and the use durability due to the red coloring is not reduced. Use durability can be improved. In addition, since there is a punching hole on the surface of the heating chamber opposite to the heater, compared to a state without the patching hole, food scraps scattered during food heating and adhered to the heater tube become minute, and further, The durability against heat generation can be improved.

When a high-frequency heating function is added to the cooking device, the heating chamber has a punching hole on the surface of the heating chamber opposite to the heater, so that there is no high-frequency leakage inside the reflector that covers the heater. This eliminates the need for a high-frequency seal portion at the heater penetration portion of the reflector.

Further, by applying an alkali-resistant coating material to the surface of the heater tube, even if food debris scattered from the food adheres to the heater when the food is heated, the heat generation durability of the heater is increased. Needless to say.
