Abstract

PROBLEM TO BE SOLVED: To enable the entire grillroom to be light in a simple structure. SOLUTION: When a burner 20 is ignited to start combustion, the cooking stuff is heated, and a flame hole for evaporation 25 catches fire, so that sodium chloride 41 is heated and evaporates. Since a throat part 23 becomes a negative pressure due to the ejection of the gas from a nozzle 31, the vapor of the sodium chloride 41 is sucked in by a vapor leading-in pipe to flow into the throat part 23, where the gas is mixed with air, the sodium chloride 41, and vapor to be fed into each cooking flame hole 21 equally. The color of the cooking flame hole 21 changes from the ordinary blue to yellow due to the flame reaction by the sodium chloride 41, and the grillroom is evenly lit up by the entire flame. Therefore, the cooking condition of the cooking stuff can be plainly confirmed through a sight glass during heating.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to further clarify the structure and operation of the present invention described above, a preferred embodiment of the gas grill of the present invention will be described below. FIG. 1 is a schematic configuration diagram of a gas grill as one embodiment of the present invention. The gas grill is provided with a tray 11 provided so as to be able to be pulled out from the inside of the grill storage 10, a grill door 12 provided on the front of the grill storage 10 and opened in conjunction with the pulling-out operation of the tray 11, and a cooking object A provided on the tray 11. And a substantially U-shaped burner 20 provided above the grill 13.
Although not shown, a hot plate, a ceiling plate, and the like are provided above the burner 20.

A viewing window is formed in the center of the grill door 12 by a transparent glass so that the state inside the grill storage 10 during cooking can be seen.

The burner 20 has a plurality of cooking flame holes 21 formed along a U-shaped inner edge portion.
A gas flow path is formed by a U-shaped hollow portion 22 and a throat portion 23 for supplying gas to the air. A gas pipe 30 for supplying gas to the burner 20 is provided at an end of the throat 23, and a nozzle 31 for injecting gas to the throat 23 is provided at a tip of the gas pipe 30. Further, as shown in FIG. 2, a damper 24 for adjusting the amount of primary air is provided in a portion of the throat portion 23 where the nozzle 31 is inserted. When gas is supplied from the gas pipe 30 and injected by the nozzle 31, primary air is sucked from the damper 24, mixed in the throat 23, and then mixed with the hollow 2.
2 and is supplied to each cooking flame hole 21.

An evaporating flame hole 25 is provided in the upper portion of the hollow portion 22 near the throttle portion of the throat portion 23, and is formed so that the flame burns and burns when burning in the cooking flame hole 21. I have. A holding device 40 for holding solid sodium chloride 41 is provided above the evaporating flame hole 25,
In the vicinity of the holding device 40, a steam introduction pipe 50 having one end connected to the throttle portion of the throat portion 23 is provided.

Next, the operation of the gas grill of this embodiment will be described. When the burner 20 is ignited and the combustion is started, the cooked product A is heated and the fire is also transferred to the evaporating flame 25, so that the sodium chloride 41 is also heated and evaporated. Since the throat portion 23 has a negative pressure due to the ejection of gas from the nozzle 31, the steam generated from the sodium chloride 41 is sucked from the steam introduction pipe 50 and the throat portion 23
The gas, air, and sodium chloride vapor are mixed in the throat section 23 and supplied to the cooking flame holes 21 evenly. The color of the flame of the cooking flame hole 21 changes from a normal blue color to a yellow color due to a flame color reaction caused by sodium chloride vapor, and the entire flame illuminates the inside of the grill storage 10 uniformly. Therefore, the cooking condition of the food A being heated can be clearly confirmed through the viewing window.

As described above, according to the gas grill of the present embodiment, the sodium chloride vapor is sucked using the structure for sucking the primary air and mixed with the gas, thereby forcing the sodium chloride. There is no need to provide a separate device for feeding, and by mixing with gas, it can be evenly supplied to each cooking flame hole 21, and a flame reaction is caused by the whole flame to lighten the whole inside of the grill storage 10. Therefore, it is possible to easily confirm the cooking condition of the food A being heated. In addition, since the inside of the grill storage 10 can be illuminated by the flame itself of the burner 20 using the flame reaction, effective illumination can be achieved at low cost. Furthermore,
By heating the sodium chloride 41 by the flame of the evaporating flame hole 25 provided in the burner 20, it is not necessary to newly provide a burner. In addition, as the amount of sodium chloride 41 decreases, the upper part of the evaporating flame hole 25 is always replenished by the holding device 40. Further, since the amount of sodium chloride 41 is slightly reduced by evaporation, the amount of sodium chloride required in the initial stage is reduced. If the sodium 41 is provided, the lighting performance can be maintained even for long-term use.

In this embodiment, the sodium chloride 41 is heated by the flame of the evaporating flame 25 provided in the burner 20, but the invention is not limited to this. For example, a separate burner for heating the sodium chloride 41 is provided. Alternatively, it may be heated by the flame of the cooking flame hole 21. Further, in the present embodiment, the vapor of sodium chloride 41 is mixed in the throat portion 23, but is not limited to the vapor, and for example, fine powder may be mixed. Further, if a chamber in which the steam generated from the sodium chloride 41 is provided and the chamber is connected to the steam introduction pipe, the generated steam can be reliably sent to the throat portion 23. Further, although the decrease due to evaporation of the sodium chloride 41 is slight, for example, the holding device 40 may be configured to be easily detachable so that it can be easily replenished when consumed. In this example, sodium chloride 4 was used to cause a flame reaction.
1 was used, but is not limited thereto, and any metal or compound thereof can be used as long as the flame color is red or yellow and a flame reaction with relatively high brightness can be obtained.

The embodiments of the present invention have been described above.
The present invention is not limited to these embodiments at all, and it goes without saying that the present invention can be implemented in various modes without departing from the gist of the present invention.
