STRUCTURE FOR COUPLING MAIN PIPE IN TOP BURNER OF GAS OVEN}

The present invention relates to a gas oven range, and more particularly, to a coupling structure of a main pipe and a control valve for supplying gas to a top burner of a gas oven range.

Generally, a gas oven is a device that cooks food by combining a gas oven using a radiant heat and convection heat by putting food in a gas range and a cavity. In more detail, a top burner section for directly cooking food by the heat of combustion of gas is installed in the upper part of the gas oven range, and an oven part is provided in the lower part to make food using mainly tropical flow of gas combustion heat. And, between the top burner portion and the oven portion is provided a roasting chamber portion for cooking food mainly using radiant heat.

Here, a plurality of top burners are installed in the top burner to generate a flame by burning gas, and the gas supplied from the outside is supplied to the top burner through a main pipe and a control valve.

The conventional coupling structure of the main pipe and the control valve of the top burner of the gas oven range is shown in Figure 1 and described with reference to this.

The main pipe coupling structure for the top burner of the gas oven range includes a main pipe 1 into which external gas is introduced, a valve connecting member 3 fixed to the main pipe 1, and a valve connecting member 3. It consists of a control valve (7) and the like to be coupled.

The main pipe 1 is provided with a gas flow passage hole of a predetermined size at a predetermined interval, and the valve connecting member 3 is fixed on the main pipe 1 so as to communicate with the gas flow passage hole. And the control valve (7) is coupled to the valve connecting member (3) via a packing (5) of a predetermined form to prevent gas leakage.

In the main pipe coupling structure having such a configuration, first, the valve connecting member 3 is welded to communicate with each other on the main pipe 1, and then the control valve 7 is predetermined together with the packing 5. It is fastened to the coupling member 3 using a coupling member, that is, a screw.

Accordingly, the gas supplied from the outside is supplied to be burned to the top burner via the main pipe 1, the valve connecting member 3, and the control valve 7.

However, the following problems occur as the above-described conventional main pipe coupling structure for the top burner is applied.

First, there is a problem in that the productivity is lowered due to the increase of the work process during production and the production cost is increased.

As mentioned above, the valve connecting member 3 is welded to the main pipe, and the communication state between the gas flow hole of the main pipe 1 and the valve connecting member 3 and the leakage of the valve should be considered during the welding process. do. Therefore, such a welding process substantially increases the working process and the working time, thereby causing a decrease in productivity and an increase in production cost.

Second, due to welding fixation of the valve connecting member, it is difficult for the main pipe coupling structure to have a uniform quality.

In practice, welding fixation is not easy to maintain a constant quality. If the valve connecting member 3 is not welded in the correct position, the control valve 7 may also not be correctly positioned. Therefore, the appearance quality may be degraded by the eccentricity of the control knobs and the nozzles respectively connected to the control valve 7, and the combustion performance may be reduced. In addition, when a defect occurs in the weld, a safety problem may occur due to gas leakage.

The present invention has been made to solve the above problems, an object of the present invention to provide a simplified structure of the main pipe for the top burner of the gas oven range.

Another object of the present invention is to provide a main pipe coupling structure for gas burner top burners having a uniform quality.
