Description

Ignition mechanism for commercial gas stoves {LIGHTER DEVICE FOR GAS BURNER}

The present invention mainly relates to an ignition mechanism that can be most preferably applied to a commercial gas stove, and more particularly, by continuously operating a part of gas from the main gas pipe to the ignition part of the burner to maintain a small flame. The present invention relates to an ignition mechanism of a commercial gas stove that can ignite a burner without performing a separate ignition operation by allowing gas to be supplied.

In general, in the case of a gas stove used in a kitchen of a restaurant such as a restaurant, to prevent ignition, a separate portable igniter is used to ignite at a relatively long distance or to use a self-ignition means mounted on one side of the burner. .

The self-ignition method of such a gas stove may be classified into a shock type using a piezoelectric element and an electric type using an ignition transformer.

In the case of the piezoelectric method, by turning the cock handle of the gas machine, the piezoelectric element is shocked while the gas is leaked to generate a high voltage, and at the same time, spark is generated from the spark plug to ignite the gas ejected to the surroundings. .

In addition, in the case of the electric type using the ignition transformer, the ignition flame is discharged continuously during one operation of the cock handle, so that the ignition is made stable to the ejected gas and the gas loss can be reduced. .

However, the piezoelectric ignition as described above has the advantage that it can be used semi-permanently because there are no consumables, but there is a technical difficulty in that gas is not supplied correctly at the timing because the spark occurs instantaneously. Even though each burner is equipped with a separate ignition transformer, it is inconvenient to rely on fine sparks and have a high ignition failure rate due to poor assembly, causing the ignition operation to be repeated several times.

In relation to the ignition method of the gas stove, Korean Patent No. 00242727 discloses a ignition device of a gas burner that can improve ignition performance by preventing discharge noise without requiring a discharge distance as the gas is heated by a heater heating method. And Patent No. 0790561 discloses a safer and smoother operation of pressing the rotary lever to supply gas to the burner head and simultaneously causing the ignition device to be ignited. A gas burner having an ignition device is disclosed.

In addition, according to Korean Patent Laid-Open Publication No. 2010-0091346, as the handle member is rotated, the gas is supplied to the burner and ejected, and at the same time, the piezoelectric element is sequentially operated twice so that the ignition operation is performed so that the gas ignition is always performed accurately. A ignition device for a gas burner is described.

However, in the prior art as described above, the burner ignition by the ignition device can be safely and easily, but causes ignition failure due to the weakening of the spark.

In particular, since the rotary lever and the handle member are installed in correspondence with the burners one by one, there is an inconvenience in that each burner must be ignited or shut off one by one. It was a factor of suffering.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to guide some of the gas from the main gas pipe to the burner side and to maintain a small flame continuously, thereby providing a valve corresponding to each burner. Burner ignition or blocking can be made only by the instantaneous opening and closing operation, as well as to provide an ignition mechanism of a commercial gas stove that can prevent the occurrence of ignition failure.

The present invention for achieving the above object is a ignition mechanism of a commercial gas stove configured to perform the inflow and shut-off of the gas in conjunction with the operation of the valve or knob, the partial gas from the main gas pipe via the branch pipe. At the same time as the branch unit for receiving, an operation knob for igniting the gas supply and the micro switch is provided at one side of the branch unit, and at the end of the distribution pipe and the power line connected to the branch unit at one side of the burner. A fixed ignition unit is provided so that a small flame can be maintained while some gas is continuously supplied when the operation knob is operated. The branch unit is connected to a branch pipe connected to the main gas pipe through a pipe unit. Corresponding to the quantity of the main body and the burner to be provided with a fastening member connected to the distribution pipe The fastening member is provided with a screw for finely adjusting the supply gas amount, and the ignition unit has an outlet pipe to which a distribution pipe is connected and a spark plug to which a power line is connected, respectively, in a single bracket so that gas injection and ignition are performed. At the same time, the first and second guides are mounted on one side of the bracket to be configured to induce the flow of gas.
