Description

Description: TECHNICAL FIELD The present invention relates to a grill ignition device for a grill provided with an infrared burner.

(Prior Art) A conventional gas stove with a grill will be described with reference to FIGS. 5 and 6. FIG. 5 and 6 are a side sectional view and a front sectional view of a main part of a conventional gas stove with a grill.

In FIG. 5, the grill portion of the gas stove has a box-shaped grill storage 1 provided with an opening 1a in the front from the center, a rectangular burner mounting opening 2a in the upper front attached to the upper portion thereof, and A grill cover 2 having an exhaust hole 2b on the side and a spark plug mounting window 2c on the side, and an infinite number of combustions mounted on the burner mounting opening 2a via a holding frame 3 having an L-shaped cross section. A burner main body 5 having a ceramic infrared burner 4 having a hole formed therein, an exhaust pipe 6 attached to the exhaust hole 2b, and as shown in FIG. 6, inserted through the ignition plug mounting window 2c. An electrode 7a, which is mounted on the grill cover 2 and bent at a substantially right angle, is composed of an ignition plug 7 mounted on an insulator 7b of an insulator.

The spark portion 7c at the tip of the electrode 7a of the ignition plug 7
Are near the combustion surface of the infrared burner 4 and the holding frame 3
It is installed so that it has a discharge distance with the inner side of.

The operation of the gas stove with grill configured as described above will be described.

First, a cooking object 8 such as fish is placed on a grill 10 placed on a grill plate 9 and inserted into the grill storage 1. next,
The gas plug (not shown) is opened, a voltage is applied to the electrode 7a of the ignition plug 7, a spark discharge is blown between the spark portion 7c and the holding frame 3, and the infrared burner 4 is ignited. The infrared burner 4 glows red, radiates far infrared rays, and burns the food 8.

(Problems to be Solved by the Invention) However, in the above configuration, since the insulator 7b of the ignition plug 7 protrudes into the grill cover 2, when used repeatedly, oil smoke generated from the cooking object 8 such as a fish. Sticks to the insulator 7b and is carbonized, and the electrode 7a, the grill cover 2 and the insulator 7b
There is a problem in that the insulation resistance between the contact points with the electrodes is lost, erroneous discharge occurs, and durability is lacking.

Also, at the time of L-shaped bending of the holding frame 3, the bending width varies depending on the material lot and the die, and the spark portion 7c is formed.
However, there is also a problem that a stable ignition performance cannot be obtained because the discharge distance from the above-mentioned range deviates from the effective ignition distance.

Further, the surface temperature of the grill cover 2 reaches about 400 to 500 ° C. due to heat conduction from the infrared burner 4, and the insulator 7 b of the ignition plug 7 is directly attached to the grill cover 2. There is also a problem that, when the temperature rises as described above, the insulation resistance decreases, and when water or the like is rapidly cooled due to water or the like, cracking occurs and erroneous discharge occurs.

The present invention solves the above-mentioned problem, and does not cause erroneous discharge even when the grill is used repeatedly.Also, it is always stable without erroneous discharge even if water is applied to the ignition plug insulator while the grill is in use. An object of the present invention is to provide a grill igniter having excellent durability and excellent durability.

(Means for Solving the Problems) To solve the above problems, the present invention provides a grill storage,
A grill cover holding an infrared burner at an upper portion of the grill storage, a spark plug mounting window provided on the grill cover, a mounting plate installed facing the vicinity of the infrared burner from the spark plug mounting window, An ignition plug having an insulator portion fixed to a mounting plate and an electrode positioned near a combustion surface of the infrared burner; and a dirt prevention wall covering the grill intake side and lower side of the ignition plug insulator. And a spark-receiving portion facing the spark portion of the electrode is provided inside the grill housing, and a holding portion for the ignition plug is provided outside the grill housing. It is to be installed.

(Operation) With the above configuration, the insulator 7b of the ignition plug 7 inserted into the inside of the grill cover 2 is covered with a dirt prevention wall from the grill intake side to the lower side or both upper and lower sides. The generated oil smoke is less likely to stick, and erroneous discharge between the contact points between the electrode 7a and the grill cover 2 and the insulator 7b of the ignition plug 7 due to the carbonization is eliminated, and the durability is improved.

Since the ignition plug 7 is mounted on the grill cover 2 via the mounting plate, the heat transmitted from the grill cover 2 is reduced, and the surface temperature does not rise above the standard value. Erroneous discharge can be prevented.

Further, when a spark-receiving portion facing the spark portion of the ignition plug 7 is formed at the tip of the mounting plate, the discharge distance between the spark portion 7c of the ignition plug 7 and the spark-receiving portion of the mounting plate can be accurately assembled, so that stable operation can be achieved. The obtained ignition performance is obtained.

(Embodiment) A second embodiment of the present invention will be described with reference to FIGS.

1 and 2 are a front sectional view of a main part of a grill portion of a gas stove with a grill and a front sectional view of a main part, showing a first embodiment.

In both figures, the present embodiment is different from the conventional example shown in FIGS. 5 and 6 in that, as shown in FIG. This is a point that it is placed on the grill cover 2 via a mounting plate 11 having a stain prevention wall 11a formed so as to cover the side and the lower side.
The other components are the same as those of the conventional example, and thus the same components are denoted by the same reference numerals and description thereof will be omitted. Further, the operation of cooking the article to be cooked 8 is not different from the conventional example, and therefore the description thereof is omitted.

In this embodiment, as shown in FIG. 1, the exhaust of the grill flows from the grill intake side toward the exhaust pipe 6 as shown by arrows A, B and C. However, the grill exhaust of the insulator 7b of the ignition plug 7 is performed. Oil smoke generated from the cooking object 8 such as fish does not adhere because of the dirt prevention wall 11a covering the side and the lower side.
Erroneous discharge due to the carbonization is eliminated, and the durability is improved.

In this embodiment, the dirt prevention wall 11a covers only the grill intake side and the lower side of the insulator 7b, but the same effect can be obtained by covering the entire circumference of the insulator.

FIG. 3 is a side sectional view of a main part of a grill portion of a gas stove with a grill showing a second embodiment, and FIG. 4 is a perspective view of the ignition device.

In FIG. 4, the present embodiment differs from the first embodiment shown in FIG.
b, a point formed in a U-shape so as to cover the grill intake side and both upper and lower sides, and an upper part of the above-described prevention wall 12a is extended to form a sparked part 12b opposed to the spark part 7c of the ignition plug 7, Further, the point is that the holding portion 12c of the insulator 7b is formed in a trapezoid. Others are the same as those of the first embodiment, and the description of the configuration and the cooking operation will be omitted.

In this embodiment, the insulator 7b of the ignition plug 7 is covered on the grill intake side and both the upper and lower sides, so that oil smoke generated from the cooked object 8 such as fish is more difficult to adhere.

The first and second embodiments are both insulators of the ignition plug 7.
Since 7b is mounted on the grill cover 2 via the mounting plate 11 or 12, heat conduction is less than when directly mounted on the grill cover 2, and the holding portion 12c of the insulator 7b is trapezoidal. The heat conduction from the grill cover 2 to the holding portion 12c itself is reduced, the surface temperature of the insulator 7b does not rise above the standard value, and the insulator 7b does not break even when exposed to water and the like, thereby preventing erroneous discharge.

Further, the ignition plug 7 is attached to the mounting plate 1 of the sparked portion 12b.
Since it is assembled integrally with the spark plug 2, the variation in the discharge distance between the spark portion 7c and the sparked portion 12b is small, and stable ignition performance can be obtained.

(Effects of the Invention) As described above, according to the present invention, the insulator of the ignition plug inserted into the inside of the grill cover is covered with oil smoke and the like generated from fish to be cooked by being blocked by the dirt prevention wall. As a result, erroneous discharge between the electrode and the contact point between the grill cover and the insulator due to the carbonization is eliminated, and the durability is improved.

In addition, the insulator of the ignition plug is mounted on the grill cover via the mounting plate, so that the heat conduction is less than when directly mounted, and the holding portion of the mounting plate is trapezoidal. The heat conduction to the holding part itself is reduced, the surface temperature does not rise above the standard value, and the insulator is not broken even when exposed to water, so that erroneous discharge can be prevented.

In addition, since the spark plug is mounted after being assembled on the mounting plate, a variation in the discharge distance between the spark portion and the sparked portion is small, and stable ignition performance can be obtained.

Therefore, a highly reliable gas stove with grill having excellent durability can be obtained.
