Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas-electric stove. BACKGROUND OF THE INVENTION With the spread and development of kitchen appliances, household stoves are also required to meet various purposes. The present invention provides a simple and rational stove that meets this demand.

Gas is usually used as the heat source for kitchen stoves in Japan, and its calorific value is 2200Kca/H.
It is said to be 3000Kca/H, and when converted to electric power, it becomes 2.6kW and 3.5kW, respectively. This is two to three times more heat than a normal electric conditioner. It is extremely difficult to obtain the same amount of heat from an electric stove as a gas stove in Japan, where the power transmission and distribution system is poor.
It can only be considered to be about 2kW, which means that it takes a long time to boil, and there is a strong impression that electric stoves generally have weak heat. For this reason, gas stoves have become popular; however, it is difficult to adjust the firepower of gas stoves, and special consideration is required for cooking that requires delicate adjustments. On the other hand, electric stoves have the advantage of being extremely easy to adjust the heat, making it easy to perform various types of cooking. If you combine these two, you can use a high-power gas burner at the beginning of cooking.
By switching to an electric heater when the food is boiled, it becomes possible to cook with the best of both worlds, and in terms of electricity and gas costs, gas, which is cheaper per calorie, can be used when a large amount of heat is required in the initial stage. It is extremely rational to switch to electricity with a higher unit price at the stage when small thermal power is required.

The present invention has been made in view of the above, and includes a gas burner section and an electric heating section in which an electric heater is built into a heating plate, and the upper end of the gas burner section is connected to the heating surface of the electric heating section. The height of the heating surface is lower than that of the heating surface, and ventilation grooves are formed in the heating surface. Embodiments of the present invention will be described below based on the drawings. First, FIGS. 1 and 2 show an embodiment of the present invention, in which 1 is a gas burner in the center, and 2 is arranged around the outer periphery of the gas burner 1 so that its upper end is higher than the upper end of the gas burner 1. A gas mixture of city gas and air, for example, flows into the gas burner 1 from a gas inlet 3, and this mixed gas is combusted in a burner head 4. On the other hand, the electric heating section 2 has a heating plate type in which, for example, a sheathed heater 6 is built in over substantially the entire circumference of the heating platen 5.
If electric power is supplied from both ends 6a, 6a of the electric heating section 2, the temperature of the heating plate 5 of the electric heating section 2 will rise. Reference numeral 7 denotes a ventilation groove formed on the upper surface of the heating plate 5 of the electric heating section 2.

The gas-electric stove of the present invention can be implemented as described above, and the following effects can be obtained.

1. At the initial stage of ignition, by using a gas burner, the flame directly hits the object to be heated (pot, etc.), and there is less energy loss due to preheating, as with a hot plate type electric heating unit or sheathed heater, which is efficient.

2 Normally, at the initial stage of heating, the heating source needs to emit a large amount of energy, and since a gas burner is used at this point, the unit price of fuel is lower than that of electricity. After that, you can use an electric heater at any stage that requires small heat.

3 The installation position of the gas burner is lower than the electric heating part [electric heater], so the flame of the gas burner hits the heated surface of the object to be heated, and this flame does not directly hit the electric heater. , it does not damage the electric heater, but rather has a preheating effect on the electric heater, reducing power loss when energized.

4. When rapid heating is required, using a gas burner and an electric heater at the same time supplies a large amount of energy to the object to be heated, which shortens the heating time or increases the temperature reached within a certain time range. I can do it.

5. When using an electric heater, cooking that meets the cooking conditions can be easily performed by controlling the supply of electric power using various control means.

6. Since the heating surface of the electric heating section has ventilation grooves, the heating surface functions as a trivet for a gas burner, and a separate trivet is not required.

7. The electric heating section is made of a heating plate, and when using the electric heating section, the heating efficiency of the heated object is good.
