Description

Gas burner for built-in

The present invention relates to a built-in gas burner, and more particularly, by installing a nozzle at the rim of the burner and allowing the burner to install a thermistor as an overheat prevention sensor, the air is still sucked in from the top of the burner, The present invention relates to a built-in gas burner capable of sensing a superheated information of a heated object heated by the burner by installing a thermistor on the burner without affecting it.

Generally, a gas burner is a device for efficiently burning gaseous fuels to utilize heat and high temperature, and there are various types, ranging from small-sized ones used for domestic winds to large-scale industrial burners used for boilers of thermal power plants, The method of mixing fuel and air is broadly classified into two types, ie, a premixed type and a diffusion type.

In recent years, a built-in gas burner for use in a kitchen sink top plate has been released.

As an example, a built-in gas burner of the prior art, as shown in FIG. 1, has a cup body 3 having a nozzle 3a installed at the center thereof, and a cup body 3 disposed above the cup body 3 and mixed at the center thereof. The tube 5a is provided and includes a burner body 5 having a flame hole 5b on the upper edge thereof and a burner head 7 mounted on an upper portion of the burner body 5.

The built-in gas burner having such a configuration opens a gas valve and ejects gas through the nozzle 3a to the upper portion of the burner body 5 so that external air is sucked from the upper part of the burner by the ejection pressure, mixed with gas, and mixed with gas. The mixed gas is continuously blown upward and hits the bottom of the burner head 7 covered on the top of the burner body 5 and then spreads radially toward the salt hole 5b and passes through the salt hole 5b. As a result, the spark is sparked by a spark of an ignition plug (not shown) as it is ejected to the outside of the burner body 5.

At this time, the required air is sucked from the burner top, so it is not affected by the internal pressure of the product in which the burner is installed.

However, such a built-in gas burner of the prior art has a problem in that it is difficult to mount the thermistor on the burner in such a manner that the gas is vertically injected directly into the burner body through the nozzle without venturi.

The present invention has been made to solve such a problem, by installing a nozzle on the burner's rim and to install a thermistor which is an overheat prevention sensor on the burner, it still inhales air from the top of the burner and affects the internal pressure. The purpose of the present invention is to provide a built-in gas burner capable of sensing the overheating information of the heated object to be heated by the burner, without installing a thermistor on the burner.

Built-in gas burner according to an embodiment of the present invention for achieving the above object is disposed in close contact with the bottom surface of the built-in top plate and provided with a space portion blocked from the gas therein, the nozzle is installed in the adjacent edge portion of the space portion Cup body; A burner body disposed on an upper portion of the cup body and having a through part communicating with the space part, a mixing tube provided at a portion directly above the nozzle, and having a salt hole at an upper edge thereof; And a burner head mounted on an upper portion of the burner body and having a through hole communicating with the through part.

In addition, in the built-in gas burner according to an embodiment of the present invention, it is preferable that at least one nozzle is installed in the space part and a mixing pipe is provided to correspond to the nozzle.

In addition, in the built-in gas burner according to an embodiment of the present invention, it is preferable that a wire passage is further provided on the closed bottom surface of the space part of the cup body.

In addition, in the built-in gas burner according to an embodiment of the present invention, a thermistor holder is disposed on the bottom surface, the lower end of which is supported by the thermistor holder, and the upper end of the through part of the burner body and the burner head. Preferably, the thermistor is further provided to the outside through the through hole.

In addition, in the built-in gas burner according to an embodiment of the present invention, the built-in gas burner, characterized in that a fastening groove for fastening and fixing the thermistor holder on one side of the bottom surface.

In addition, in the built-in gas burner according to an embodiment of the present invention, a wire guide groove for guiding the thermistor holder wires that exit from the wire passage port to one side of the cup body is embedded in the bottom surface of the cup body. It is preferable that it is further provided.

In addition, in the built-in gas burner according to an embodiment of the present invention, a spreader is provided at the upper end of the mixing tube of the burner body, but the spreader is preferably configured to protrude upwards so as to be positioned higher than the bottom surface of the burner body. .

In addition, in the built-in gas burner according to an embodiment of the present invention, when at least two or more nozzles are installed, the gas to be ejected from these mixing tubes is separated from the bottom surface between the mixing tubes of the burner body. It is preferable that a partition wall is provided.

As described above, the built-in gas burner according to the present invention allows the nozzle to be installed at the rim of the burner and the thermistor as an overheat prevention sensor to be installed at the burner, thereby still sucking air from the upper part of the burner to prevent internal pressure. Thermistors are installed in the burner without affecting them, and the superheat information of the heated object heated by the burner can be sensed evenly.
