Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a one-port type halogen stove mainly used for a tabletop, in which a heating surface is made of heat-resistant glass and a lamp heater having a built-in heater such as a halogen lamp is used as a heat source.

[0002]

2. Description of the Related Art Conventionally, as a cooker using a lamp heater emitting infrared rays as a heat source, a smooth stop type cooker having a flat heating top portion for mounting a heating vessel has been generally used.

FIGS. 3 and 4 are an external view and an enlarged sectional view showing the configuration of a conventional heating cooker 1, respectively. As shown in the figure, the heating top section 3 is made flat by heat-resistant glass 4 such as crystallized glass that transmits infrared rays, and a heat source section 5 is provided immediately below the heating top section 3. The heat source unit 5 has a plurality of lamp heaters 6 radiating infrared rays therein, and has an upper surface opening abutted on the heat-resistant glass 4 of the heating top unit 3 by a spring 7.

[0004] The portion of the heat-resistant glass 4 directly above the heat source section 5 where the lamp heater 6 is disposed is the heating zone area 4a, which is heated by the lamp heater 6 to a high temperature. The area other than the heating zone 4a of the heat-resistant glass 4 is the non-heating zone 4b. The lamp heater 6 emits high heat through the quartz tube when the energization is started, and heats the heating vessel 2 on which the heating zone 4a of the heat-resistant glass 4 immediately above is placed.

[0005]

However, in the conventional heating cooker 1 in which the heat-resistant glass 4 is used as the heating top portion 3, a wire mesh is placed on the heat-resistant glass 4 to cook grilled foods or to directly put food on the heat-resistant glass 4. Cooking on top of the stove causes severe sticking of dirt, and if it becomes firmly deposited, the difference in thermal expansion may lead to cracking of the heat-resistant glass 4 or the transmission of infrared rays will be significantly reduced, reducing the efficiency of the stove. Such use cannot be performed because of danger of squatting, and there is a problem that the cooking range and menu are considerably restricted due to adhesion of dirt and sticking due to heat.

[0006]

According to the present invention, there is provided a heat-resistant glass having a coating layer formed on a surface of a heat-resistant glass on which a heating vessel is mounted, wherein the temperature sensor is incorporated in a stove. The temperature of the surface is detected and the temperature is controlled at the usable temperature of the coating layer.

[0007] With this configuration, cooking can be performed by placing a net or food directly on the heat-resistant glass surface, and the food and fats and dirt from the food do not firmly adhere to the heat-resistant glass. There is an effect that the cooking range and the cooking menu as the tabletop cooker are greatly expanded.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a heat-resistant glass on which a heating vessel is placed, a stove having a halogen lamp radiating infrared rays directly below the heat-resistant glass as a heat source, and a temperature sensor for detecting the temperature of the heat-resistant glass. Wherein the temperature sensor controls the temperature of the heat-resistant glass to a certain temperature or less so that heating and cooking can be performed directly on the heat-resistant glass surface, and a coating layer is formed on the surface of the heat-resistant glass. It was done.

Further, the temperature is controlled at the usable temperature of the coating layer formed on the surface of the heat resistant glass.

Further, the coating layer on the surface of the heat-resistant glass is a fluorine film. Then, fish, meat, and other various ingredients can be directly placed on the heat-resistant glass for cooking. Since the coating layer is extremely excellent in heat resistance, it can be cooked without shortage of heat even when controlled at a temperature lower than the usable temperature, and there is no sticking of various stains, fats and juices from foods.

As described above, cooking can be performed directly on the heat-resistant glass surface, and the same applies to grilled food using a wire mesh. Since the coating layer is a film having excellent heat resistance, the heating power does not become insufficient even by heating and cooking with a normal heating container placed thereon.

It is possible to provide a halogen stove that is clean and highly safe and has a greatly enhanced cooking range.

An embodiment of the present invention will be described below with reference to the drawings. (Embodiment) FIGS. 1 and 2 are an external view and an enlarged sectional view of a halogen stove according to an embodiment of the present invention. In the figure, a halogen stove 8 of the present invention is a heat-resistant glass 9 using crystallized glass.
In addition, a stove section 11 having two halogen lamps 10 as heat sources is provided immediately below the heat-resistant glass 9. The stove 11 is opened at the top and is in contact with the heat-resistant glass 9 by a spring 13.

The heat-resistant glass 9 has a heating zone area 9a and a non-heating zone area 9b, and the heating zone area 9a is located immediately above the stove section 11 where the halogen lamp 10 is disposed.
This is a portion where the temperature is increased by infrared rays emitted from the halogen lamp 10.

A temperature sensor 14 is built in the stove section 11, and the temperature sensor 14 is brought into close contact with a lower portion of a heating zone 9a where the temperature of the heat-resistant glass 9 is high by a spring 15. A fluorine coating layer 16 is formed on the surface of the heat-resistant glass 9.

Next, the operation and operation will be described. When electricity is supplied to the halogen lamp 10 of the halogen stove 8, high heat is generated through the quartz tube, and the temperature of the heat-resistant glass 9 gradually increases.
Although the temperature of the fluorine coating layer 16 on the surface of the heat-resistant glass 9 also rises, the temperature sensor 14 detects the temperature of the heating zone 9a of the heat-resistant glass 9 and controls the temperature so as not to exceed a certain temperature. Things. This makes it possible to stably prevent dirt from adhering and sticking to the heat-resistant glass 9 surface without the risk of the fluorine film being deteriorated by heat, and to secure a long and clean heating surface.

Here, the temperature of the heat-resistant glass 9 is different between when there is a load on the heat-resistant glass 9 and when there is no load. In this embodiment, the temperature of the heating zone 9a is set to 260 ° C. or more.
The temperature is detected and controlled by the temperature sensor 14 so as to be not higher than 00 ° C.

Considering the heat resistance and durability of the fluororesin, the presence or absence of a load, etc., it can be said that it is appropriate to control the upper limit of the temperature at about 300 ° C., and at such a temperature, most of the cooking becomes insufficient in heat. It can be performed without any problem, and has no thermal effect on the coating film of fluorine. The upper limit and lower limit of the control temperature, the width thereof, and the like can be arbitrarily set, and are not particularly limited. Needless to say, the heating can be carried out by placing the heating container 12 as shown in FIG.

[0019]

As is apparent from the above description, the halogen stove of the present invention has the following effects.

A temperature sensor is built in to detect the temperature of the heat-resistant glass, and the temperature is controlled at a usable temperature of the fluorine coating layer on the heat-resistant glass to stabilize the heat of the fluorine film. In addition to cooking, it has become possible to perform grilling cooking, which was not possible in the past, and cooking in which ingredients are directly placed on the heat-resistant glass 9, without causing problems caused by dirt on the heat-resistant glass 9. It has the advantageous effect that it can be greatly expanded and the heating top surface can always be kept clean and sanitary.
