Abstract

PROBLEM TO BE SOLVED: To restrain the variability in the baking of food stuff for cooking by a method wherein a gas grill for cooking is provided with a unit, flying the heat of flame, generated by a gas burner inwardly, to a distant place, and another unit, flying the same to a near place. SOLUTION: Air intake ports 13 are provided at the upper part of gas burners 4, arranged on both side walls 3a of a grill chamber 3 so as to be opposed, and flow regulating plates 14, slanted downward, are provided above the air intake ports 13. A gas burner is constituted of upper and lower plates 6, 7, which are connected, while the superposed unit 11, directed inward, is provided with a downward eaves 11a, faced inward and downward, whereby the area of air passage K is reduced and, as a result, the heat of flame is flown to a near place. On the other hand, a flame port 10 below the downward eaves, forms downwardly slanted flame and the flame is pushed down by the downward eaves unit, and further, the heat of flame is flown to a distant place by the downwardly slanted air stream, passing through the air passage K. On the other hand, a flame port below the upward eaves 11b forms flame horizontally substantially while the effect of pushing down the flame by the upward eaves is small.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking gas grill and a gas burner for cooking by heat generated by gas combustion.

[0002]

2. Description of the Related Art As a conventional cooking gas grill, gas burners extending horizontally are arranged on both side walls of a grill chamber, an air intake port for taking in combustion air is provided on the gas burner, and a rectifying plate is provided on the gas burner. Is known. The above-mentioned flow straightening plate has an effect of preventing combustion broth and the like from adhering to the flame outlet, and an effect of guiding combustion air entering from the air intake to the flame. For this reason, the air for combustion is supplied inward from the upper side of the flame by the flow straightening plate, and as a result, the action of blowing the heat of the flame inward by the flow of the air for combustion occurs.

[0003]

SUMMARY OF THE INVENTION A cooking gas grill is
There is a high demand for suppressing unevenness in cooking. Therefore, by changing the amount of combustion air flowing between the straightening vane and the burner between large and small portions to suppress burning unevenness, the change is made by changing the opening area at the air intake, etc. Since the heat was applied, the degree of change was reduced until the flame actually reached the flame outlet, and the heat of the flame could not be effectively scattered far and near to broaden the heat distribution.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to effectively disperse the heat of a flame far and near, thereby suppressing unevenness in cooking of a cooked food. In providing a cooking gas grill and a gas burner.

[0005]

The present invention employs the following technical means to achieve the above object. [Claim 1] A gas grill for cooking is arranged in a substantially cubic container-like shape and a side wall of the grill room extends in a horizontal direction, and the flame blows out the inside of the grill room. A cooking gas burner with a mouth. An air inlet is provided on the side wall of the grill chamber above the gas burner. A rectifying plate is provided in the grill chamber for guiding air that has entered the grill chamber from the air inlet to a flame outlet of the gas burner. The gas burner is provided with an eave located above the flame outlet, and the eave has a tilt angle that changes toward the inside of the grill chamber in the longitudinal direction.

[Means of Claim 2] The gas grill for cooking is
A grill chamber having a substantially cubic container shape, and a cooking gas burner having a flame outlet for blowing a flame into the inside of the grill chamber are arranged to extend horizontally on respective side walls of the grill chamber. An air inlet for taking in combustion air is provided on a side wall of the grill chamber above the gas burner. A straightening plate is provided in the grill chamber to guide combustion air entering the grill chamber from the air inlet to a combustion portion of the gas burner. The gas burner is provided by joining two upper and lower plates, and the flame outlet faces the inside of the grill chamber, and
The overlapping portion of the two plates is provided below as an eaves. The eave above the flame outlet is provided with a change in the inclination angle facing the inside of the grill chamber.

[Claim 3] In the cooking gas grill according to claim 1 or 2, the change in the inclination angle of the eaves of one gas burner and the change in the inclination angle of the eaves of the other gas burner opposed thereto. Are provided so as to be shifted so as not to face each other.

According to a fourth aspect of the present invention, in the gas grill for cooking according to any one of the first to third aspects, the eave above the flame opening is a downward eave portion inclined inward and downward, and the downward eave portion. And an upward eaves portion that is inclined inward and upward as compared to the above.

According to a fifth aspect of the present invention, in the cooking gas grill of the fourth aspect, the upward eaves provided on one gas burner and the upward eaves provided on the other gas burner opposed thereto do not face each other. It is characterized by being provided so as to be shifted.

According to a sixth aspect of the present invention, in the gas grill for cooking according to any one of the first to fifth aspects, a flame port provided below an eave having a large downward inclination angle blows inward and downward. The flame outlet provided below the eaves having a small downward inclination angle is directed upward as compared with the flame openings provided under the eaves having a large inclination angle.

According to a seventh aspect of the present invention, in the cooking gas grill according to any one of the second to sixth aspects, the upper plate constituting the gas burner is formed by crimping a piece of caulking to cover an end of the lower plate. The caulking piece is provided on the flame port side of the eaves.

In the gas burner, a gas passage is formed inside by joining two plates, and a flame outlet for blowing gas supplied into the gas passage to the outside is formed. Extending in one direction, the flame outlet,
The overlapping portion of the two plates is provided as an eave in the vicinity thereof, and the eave in the vicinity of the flame port is provided with a changed inclination angle.

[0013]

Since a straightening plate for guiding the combustion air entering from the air intake to the combustion portion is provided at the upper part of the gas burner, there is a problem that broth or the like scattered from above adheres to the gas burner. Can be suppressed. Further, since the flame outlet faces the inside of the grill chamber, a flame directed toward the center of the grill chamber is formed in the gas burner. At this time, the combustion air is sucked in from the air intake above the gas burner and supplied to the combustion portion by the flow straightening plate. As a result, the heat of the flame is dissipated inside the grill chamber.

On the other hand, in the gas burner, since the eaves are provided on the upper part of the flame forming the flame, even if the broth or the like adheres to the gas burner, the eaves on the upper part of the flame allow the broth or the like to cover the flame. Avoid blocking problems. In a gas burner formed by joining two upper and lower plates, the eaves are formed by a superposed portion of the two plates, so that the eaves can be provided without using separate parts.

[0015] The eave above the flame opening is provided with a varying inclination angle toward the inside of the grill chamber. An eave with a large inward downward inclination angle (not necessarily an inwardly downward inclination but a downward inclination as compared with a portion with a small inclination angle) is formed at the lower flame outlet. The effect of suppressing the flame is great, and the combustion air flowing along the upper surface of the eaves also acts to flow downward. As a result, the heat of the flame can be blown away.

Conversely, an eave with a small inward downward inclination angle (meaning upward as compared to a part with a large inclination angle)
Has a small effect of suppressing the flame formed in the lower flame port, and the combustion air flowing along the upper surface of the eaves also has
Since the air flows upward in comparison with the portion having a large inclination angle, the heat of the flame is consequently blown away.

As described above, the provision of the portion for dispersing the heat of the flame to the far side and the portion for dispersing the heat to the near portion suppresses uneven heating in the grill chamber, and consequently reduces unevenness in cooking of the food. . Further, by providing the change in the inclination angle of the eaves of one gas burner and the change in the inclination angle of the eaves of the other gas burner opposed thereto so as not to be opposed to each other, the uneven heating in the grill chamber can be efficiently reduced. It is possible to suppress the unevenness in cooking of the food.

Further, by changing the direction of the flame blown out from the flame opening under the eaves according to the change in the inclination angle of the eaves,
It is possible to increase the ratio of the eaves having a large inward downward inclination angle and the eaves having a small inward downward inclination angle to disperse the heat of the flame.

Even when the gas burners 4 are extinguished, the flame is ignited to keep both gas burners 4 in an ignited state.

(Explanation of Two Gas Burners 4) Inside each of the two gas burners 4 (inside of the grill chamber 3), a cooking flame is formed toward the center of the grill chamber 3 as shown in FIG. Ports 10 are arranged in rows. The flame port 10 is provided on the surface of the lower plate 7 facing the inside of the grill chamber 3, and is provided so as to direct the flame formed in the flame port 10 to the inside. The angle of inclination of the flame outlet 10 will be described later.

The upper side of the flame port 10 is covered by the overlapping portion 11 of the upper plate 6 and the lower plate 7 as an eave.
The overlapping portion 11 as the eave is provided with a change in the inclination angle facing the inside of the grill chamber 3. Specifically, as shown in FIG. 5, the overlapping portion 11 at the upper portion of the flame outlet 10 includes a downward eave portion 11a inclined inward and downward, and the downward eave portion 11a.
And an upward eaves portion 11b that is inclined inward and upward as compared with. As shown in FIG. 6, the downward eaves portion 11a of this embodiment is inclined downward with respect to the horizontal direction, and the inclination angle is set to, for example, about 30 °. Also,

It is provided. Specifically, as shown in FIGS. 2 and 3, the upward eaves 11b of one gas burner 4 and the upward eaves 11b facing the other gas burner 4 are provided so as to be shifted from each other so as not to coincide with each other. ing.

Further, in this embodiment, the downward eaves 11
As shown in FIG. 6, the flame outlet provided below the upper eaves 11a is provided so as to blow inward and downward substantially along the inclination of the downward eaves portion 11a. It is provided so as to blow out the flame almost along the slope of the upward eaves portion 11b so as to blow out the flame inward and upward as compared with the flames blown out from the flame outlet provided below the downward eaves portion 11a (see FIG. 7). .

The overlapping portion 11 includes the above-described joining margin 6a of the upper plate 6, the joining margin 7a of the lower plate 7, and the swaging piece 6b. On the side. The inside of the upper surface bulging portion 12 of the upper plate 6 (the inside of the grill chamber 3) is provided so as to be inclined downward and inward so as to be substantially straight along the downward eaves portion 11a.

(Description of Air Inlet 13 and Rectifier Plate 14) Two gas burners 4 are provided on both side walls 3a of the grill chamber 3.
An air intake 13 for guiding combustion air into the grill chamber 3 is provided at an upper portion of the grille 3. Also, on both side walls 3a,
A rectifying plate 14 is provided for guiding combustion air entering the grill chamber 3 from the air intake 13 to the flame formed in the flame port 10. The rectifying plate 14 covers the upper side of the gas burner 4 and is provided so as to be inclined downward inward so as to form an air passage K inclined downwardly inward. In this embodiment, the current plate 14 is provided so as to protrude further inward than the tip of the overlapping portion 11.

(Explanation of the operation of the two gas burners 4) When the gas burners 4 are burned, a flame is blown out from the flame openings 10 of the gas burners 4 toward the inside of the grill chamber 3 below the grill Y on which the food A is placed. At this time, the combustion air enters from the air intake 13 provided in the upper part of the gas burner 4, and the entered combustion air is supplied to the flame while inclining downward along the straightening plate 14.

Here, as shown in the left side of FIG. 1 and FIG. 6, the downward eaves 11a having a large inward downward inclination angle are
The effect of suppressing the flame formed in the lower flame port 10 is great. In addition, there is an effect that the combustion air flowing along the upper surface of the downward eaves portion 11a is inclined downward and flows. As described above, the downward eaves portion 11a has a large effect of suppressing the flame and a large effect of flowing the combustion air flow downward, so that the heat of the flame is blown away. Further, in this embodiment, since the direction of the flame opening 10 below the downward eaves portion 11a is provided downward, the flame is formed inward downward.
The heat of the flame formed by the flame outlet 10 below the downward eaves portion 11a is
Can fly farther.

On the other hand, as shown in the right side of FIG. 1 and FIG. 7, the upward eave portion 11b having a small inward downward inclination angle is
The effect of suppressing the flame formed in the lower flame port 10 is small. Further, the combustion air flowing along the upper surface of the upward eaves portion 11b flows upward as compared with the downward eaves portion 11a. Further, since the upward eaves portion 11b narrows the air passage K between the upward eaves portion 11b and the current plate 14, the downward eaves portion 11b is used.
The inflow of combustion air is smaller than the inflow of air at a. As described above, the upward eaves portion 11b has a small effect of suppressing the flame, has a small effect of flowing the combustion air flow downward, and has a weak flow of the combustion air. It is harder for the heat of the flame to fly far away than when it flies. Further, in this embodiment, since the direction of the flame port 10 below the upward eaves section 11b is directed substantially in the horizontal direction, the flame is directed upward as compared with the flame of the flame port 10 below the downward eaves section 11a. This action also makes it difficult for the heat of the flame formed by the flame port 10 below the upward eaves portion 11b to be scattered farther.

(Effect of Embodiment) As shown in the above operation, the heat of the flame formed in the flame outlet 10 below the downward eaves 11a having a large inward downward inclination angle is reduced by the inward downward inclination angle. Since the heat is blown farther than the heat of the flame formed in the flame outlet 10 below the small upward eaves portion 11b, the uneven heating in the grill chamber 3 is suppressed, and as a result, the unevenness in the cooking of the food A is suppressed.

The upward eaves 1 of one gas burner 4
1b and the upward facing eaves portion 11b facing the other gas burner 4 are provided so as to be displaced so as not to coincide with each other.
The overlap (opposition) of the short portion of the broken arrow in FIG. 3 (the portion where the heat of the flame of the upward eaves portion 11b does not fly far) is prevented.
For this reason, the uneven heating in the grill chamber 3 is efficiently suppressed, and the uneven cooking of the food A is reliably suppressed.

Further, in this embodiment, the downward eaves 11
a, and the inclination angle of the upward eaves portion 11b,
Change the direction of the flame that blows out from the flame outlet 10 under each,
The change that blows out the heat of the flame is made even bigger.

On the other hand, since the upper part of the gas burner 4 is covered by the rectifying plate 14, the air flowing between the rectifying plate 14 and the overlapping portion 11 as the eaves is effectively changed by the change of the inclination angle. In addition, it is possible to prevent the broth or the like scattered from the cooking A from adhering to the gas burner 4. Further, since the polymerization section 11 covers the top of the flame 10, even if the broth or the like adheres to the gas burner 4, the trouble that the broth or the like directly goes to the flame 10 can be suppressed, and the clogging of the flame 10 can be suppressed. Can be.

In this embodiment, the swaging piece 6b is below the overlapping portion 11. On the contrary, if the crimping piece 6b is on the upper side, a concave portion is formed at the end of the crimping piece 6b, causing a problem that oil, moisture, or the like accumulates at the end of the crimping piece 6b.
However, in this embodiment, the caulking piece 6b is
, There is no problem that oil, moisture, etc. accumulate at the end of the caulking piece 6b.

FIG. 8 shows another embodiment, in which a separate eave 110 is attached to a pipe-shaped burner 41 by welding. The eaves 110 also have a downward eaves 110a inclined inward and downward in the longitudinal direction alternately in the longitudinal direction of the grille, and an upward eaves 110b inclined inward and upward in comparison with the downward eaves 110. And And, as in the above embodiment, the flame outlet under the downward eaves 110a inclined inwardly downward is smaller than the flame outlet 100 below the upward eaves 110b inclined upwardly inside. It is formed downward. Further, the upward eaves portion 110b of one burner 41 and the other burner 4
One upward eaves portion 110b is arranged so as not to face each other.

[Modification] In the above embodiment, the overlapping portion 11 (for example, the downward eaves portion 11a) on the flame opening 10 is inclined from the root portion (outside) to the tip (inside). Although shown, as shown in FIG. 9, an inclination may be provided only on the tip side of the overlapping portion 11 above the flame port 10, and the inclination may be changed in magnitude. This may be applied to the example of FIG.

In the above embodiment, the inclination angle of the overlapping portion 11 is changed in two steps (a downward eaves portion 11a and an upward eaves portion 11a).
Although b) has been described, it may be provided so that the inclination angle of the overlapping portion 11 changes to three or more steps. In the above-described embodiment, an example in which the lowermost overlapping portion 11 is inclined downward from the horizontal direction (downward eaves portion 11a) is shown. However, the inclination of the lowermost overlapping portion 11 is set to the horizontal direction or upward from the horizontal direction. And other portions may be further inclined upward. That is, by changing the inclination angle of the overlapping portion 11, the distance over which the heat of the flame is blown off is changed. This may be applied to the example of FIG.

In the above embodiment, the change in the inclination angle of the overlapping portion 11 of one gas burner 4 and the change in the inclination angle of the overlapping portion 11 of the other gas burner 4 opposed thereto are alternately shifted. Although an example has been shown, the change in the inclination angle of the overlapping portions 11 on both sides may be provided at random. Alternatively, depending on the shape of the grill chamber 3, the supply of combustion air, or the supply of gas, etc., the polymerization section is used to adjust a location where the heat of the flame does not fly too much or a location where the heat of the flame does not fly. The inclination angle of 11 may be changed in magnitude. This may be applied to the example of FIG.

In the above-described embodiment, an example has been described in which the two gas burners 4 are provided integrally with the fire transfer burner 5, but the present invention may be applied by providing the two gas burners 4 separately. In the above embodiment, an example in which the present invention is applied to the cooking gas grill 1 incorporated in the gas stove 2 is described. However, the present invention may be applied to other cooking gas grills such as a dedicated cooking gas grill. This may be applied to the example of FIG.
