The present invention relates to a temperature control apparatus of a gas oven range, and more specifically, to a temperature control of a gas oven range which prevents the ceramic glass installed in the gas oven range from being overheated and damaged by the temperature rise and radiant heat inside the gas oven range. Relates to a device.

The gas oven range is provided with an oven unit, a grill unit, and a top burner unit all in one apparatus, so that various dishes can be cooked individually or simultaneously.

A typical form of the conventional gas oven range as described above is shown in Figure 1, briefly described, the oven portion (1) is mainly installed on the lower side of the appliance mainly for barbecue cooking using the thermal power and tropical flow. On the upper side of the oven unit 1, a grill unit 2 mainly comprising grilled fish using tropical flow is installed, and on the upper portion of the grill unit 2, a plurality of vessels for heating food containers are contained. The top burner part 4 which is provided so that the burner 3 may be exposed to the upper side is provided.

In addition, a back guard part 5 for discharging the exhaust gas generated from the oven part 1 and the grill part 2 to the outside is coupled to the rear of the apparatus, and a barbecue motor is connected to the rear part of the oven part 1. (Not shown) and a convection motor (not shown) are provided.

However, the conventional open burner type gas oven range has various inconveniences in use.

First, since the flame generated from the burner 3 of the top burner unit 4 is exposed to the outside, there is always a risk of fire. Second, when the food is heated, the broth contained in the container overflows and is easily extinguished. Fourth, the bad air is easily blocked by broth or foreign substances, and the combustion defect is generated. Fourth, harmful gas generated during combustion can be inhaled by the user. I had these bad problems.

The hidden burner type gas oven range was developed to solve various problems in the open burner type gas oven range as described above.

Hidden burner type gas oven range uses a heating coil to heat using electricity instead of a burner of the top burner, and covers the upper part with ceramic glass, and uses the radiant heat generated when heating the heating coil. It consists of heating food or containers placed on the upper surface, but this hidden burner type gas oven range does not have easy economical installation or use due to its poor economic efficiency due to the high power consumption of heating heating coils. I had a problem.

In consideration of the economical problem in the above-described hidden burner type gas oven range, the development of a hidden burner type gas oven range using radiant energy by gas fuel is being developed instead of electric energy.

However, in the hidden burner type gas oven range using the radiant energy generated by the gas fuel as described above, when the wavelength of the radiant heat is changed for a long time, the ceramic glass that transmits the radiant heat is overheated or the internal temperature rises. The ceramic glass may be overheated and broken.

The main object of the present invention devised in view of the above point is in a new concept gas oven range that solves the problems described above, the user can conveniently prevent the ceramic glass of the gas oven range is damaged by overheating It is to provide a temperature control device of the gas oven range that can be used.
