The grill storage 22 includes a grill 24 provided at a middle stage for placing the food F, and a lower stage. And a tray 26 that can be slid out and pulled out with the grill 24 placed thereon. The receiving tray 26 is coated with a fluororesin.

As shown in FIG. 3, a handle 28 fixed integrally with the tray 26 and pulling the tray 26 forward is provided at the center of the front of the grill storage 22, and an opening / closing door 32 which opens and closes in conjunction with the tray 26 when the tray 26 is pulled out. The opening / closing door 32 is provided with a viewing window 30 made of glass. When the handle 28 is pulled out to the front, the pan 26 fixed to the handle 28 slides on the bottom surface of the grill storage 22 and the grill 2 placed on the pan 26
4 is pulled out of the grill storage 22 at the same time.

As shown in FIG. 2, burners 60 for burning the mixed gas and heating the object to be cooked F are arranged on both left and right sides of the grill 24. The burner 60 is a Bunsen-type burner in which air required for combustion is supplied by primary air and secondary air. The inner nozzle has a horizontal nozzle 61 and an upper nozzle 69 arranged along the depth direction of the grill storage 22. (To be described later), a flame port array is formed. The horizontal nozzles 61 are horizontal flame ports which are inclined downward slightly from the horizontal and face each other in order to cause the flame to blow out in the horizontal direction inside the grill storage 22 below the grill 24, and the upper nozzle 69 is an upward nozzle. This is the upper flame outlet for jetting the mixed gas.

More specifically, this burner 60 is similar to that shown in FIGS.
As shown in FIG. 7, a pipe 66 serving as a burner main body and a plurality of horizontal nozzles 6 orthogonally connected to the pipe 66 at equal intervals.
1 and an upper nozzle 69. The pipe 66 is a straight pipe having a circular cross section, the distal end is closed, and a gas pipe 66a is connected to the proximal end. Horizontal nozzle 61 and upper nozzle 69
Are attached to the side and upper part of the pipe 66 slightly below, respectively, and the male screw part 62 at the base end is connected to the ring-shaped lateral connecting body 67 and the upper connecting body 68 each having a female screw part formed on the inner periphery. It can be connected to the pipe 66 by screwing. Further, in the horizontal nozzle 61, a gas passage 63 having an open end and communicating with the pipe 66 is formed. When the gas passage 63 is connected to the pipe 66, a small-diameter nozzle hole 64 is formed. On the tip side of the nozzle from the nozzle hole 64,
A pair of air holes 65 are provided to allow the gas passage 63 to communicate with the outside. The shape of the upper nozzle 69 is the same as that of the horizontal nozzle 6.
1 is the same as that of FIG. An ignition electrode (not shown) is provided facing the burner 60.

As shown in FIG. 3, an exhaust chamber 50 is provided at the back of the grill cabinet 22 through a partition wall 51, and is opened to the partition wall 51 to communicate the grill cabinet 22 with the exhaust chamber 50. An opening 53 is provided below the grill 24, and an exhaust path is configured such that after the combustion exhaust gas is once trapped in the grill storage 22, the exhaust gas is discharged from the exhaust port 52 through the communication port 53 and the exhaust chamber 50. . In particular, in this embodiment, the communication port 53 is provided below the horizontal nozzle 61,
The combustion exhaust gas is also stored in the grill storage 22.

An air supply passage 29 is formed at the bottom of the grill storage 22, as shown in FIG. Part of the air taken in from the air supply passage 29 is supplied to the burner 60 as secondary air for combustion, and the remaining air is supplied to the exhaust chamber 50 by combustion exhaust.
Due to the draft force generated when the gas is discharged upward, the gas flows through the bottom of the grill storage 22 in the depth direction, cools the receiving tray 26, and is discharged together with the combustion exhaust gas. The grill top plate 25 serving as the ceiling surface of the grill storage 22 is formed in two mountain shapes in which the widthwise central portion of the grill storage 22 is slightly lowered, and guides the rising combustion exhaust gas to the center of the grill storage 22. ing.
Further, far-infrared paint is applied to the grill top plate 25.

With the above configuration, when the operation button 58 is pressed, the on-off valve for opening and closing the gas flow path to the burner 60 is opened. At this time, in the burner 60, the fuel gas is supplied from the pipe 66 to the horizontal nozzle 61 and the upper nozzle 69. Further, in the gas passage 63 of the horizontal nozzle 61 and the upper nozzle 69, the fuel gas is ejected from the pipe 66 at a high ejection speed utilizing the supply pressure of the fuel gas, and the fuel gas flows through the narrow nozzle hole 64 at a higher speed. The primary air is sucked from the air holes 65 by the injection effect at the time of passing, is ejected as a mixed gas, and is ignited by continuous discharge of the ignition electrode.

The flame of one nozzle ignited by this ignition is sequentially ignited to the adjacent nozzle, and as shown in FIG. 2, a flame is generated from the openings of the horizontal nozzle 61 and the upper nozzle 69 to cause the entire burner 60 to burn. Ignite. The lower burner provided below the grill of the conventional double-sided grill is 1 mmH
_{Although the} flame was formed at the ejection pressure of about ₂ O, the burner 60 of the present embodiment utilizes the supply pressure of the fuel gas, so that the ejection pressure becomes about 100 to 140 mmH ₂ O and the ejection speed is high. The flame is formed long forward.

The flame of the horizontal nozzle 61 is formed on the lower surface of the grill 24 and directly heats the lower surface of the object F, while the high temperature combustion exhaust gas generated from the upper nozzle 69 is indicated by an arrow in FIG. As described above, when it rises and hits the grill top plate 25, it flows to the center, and the left and right combustion exhausts merge and convect downward toward the food F to heat the upper surface of the food F. Since the communication port 53 is provided below the grill 24, the combustion exhaust gas from the upper nozzle 69 temporarily stays above the communication port 53 in the grill storage 22 for a relatively long time.
From the exhaust port 52 through the exhaust chamber 50. In this way, the upper and lower surfaces of the object to be cooked F are simultaneously heated and cooked.

Therefore, the object to be cooked F is heated by the hot air trapped in the grill storage 22, so that the heat efficiency is improved, energy is saved, and it is economical. Burner 60 to grill storage 2
2, the height direction in the grill storage 22 is widened, and the thick cooking object F can be heated and cooked.

Further, since the central portion of the grill top plate 25 is formed slightly lower, the raised combustion exhaust gas is collected at the central portion, and is placed in the central portion which is far from the burner 60 and receives less heat. The heating of the object to be cooked F is supplemented, and the entire object to be cooked F is evenly burned. In addition, since the far-infrared paint is applied to the grill top plate 25, the grill top plate 25 heated by the combustion exhaust emits far-infrared rays, and the object to be cooked F can be baked to the inside like a charcoal grill. Yes, and it has improved thermal efficiency.

Since the burner 60 has a longer flame and can effectively heat the central portion of the grill 22, the object to be cooked F can be evenly heated together with the heating effect of the combustion exhaust gas, and the uneven grilling can be achieved. Does not occur. As a result, even if the gas consumption (input) is small, the central portion of the grill storage 22 is sufficiently heated and becomes economical.

In the burner 60 capable of heating and cooking with this small gas consumption, the radiant heat is small because the flame is basically Bunsen flame, and the upper nozzle 69 for heating the upper surface of the object to be cooked F faces upward. Therefore, the temperature rise near the lower stage of the grill storage 22 can be suppressed, and the tray 26 can be cooled by the air taken in from the air supply passage 29 formed at the bottom of the grill storage 22.
The baked fat G accumulated in 6 is hardly ignited. Also,
Even if the receiving tray 26 is coated with fluorine, there is no fear that it will be peeled off by heating, and the baked fat G can be easily wiped off and cleaning can be easily performed.

Generally, in order to uniformly heat the lower surface of the object to be cooked F to the center, it is necessary to increase the gas consumption of the lower flame. However, in this embodiment, the flame is formed from the horizontal nozzle 61 at a high ejection speed. As a result, the flame reaches the vicinity of the center of the grill 22 with a small gas consumption, and the heating of the pan 26 can be further suppressed.

As a result, the grill can be properly used as a waterless grill that does not fill the tray 26 with water. In other words, prior to cooking, it is not necessary to put water in the saucer 26 for receiving the baked fat G, or to drain the water after the cooking is completed, so that the usability is good. Moreover, it is possible to prevent the baked fat G from being ignited due to forgetting to add water, so that it can be used with confidence. Further, since water is not used for heating and cooking, the object to be cooked F can be roasted.

Second Embodiment Next, a double-sided grill 21 as a second embodiment will be described with reference to FIGS. It should be noted that parts different from the first embodiment will be described,

A combustion exhaust passage 41 through which the combustion exhaust from the upper nozzle 69 of the burner 60 passes is formed above the burner 60.

The upper portion of the guide wall 37 is cut out in a rectangular shape at the center, and the both sides abut on the grill top plate 27, so that the cut-out portion forms an upper inlet 42 (shown by hatching in the figure). ing. At the lower end of the upper inlet 42, an upper guide 43 bent obliquely upward toward the center of the grill storage 23 is formed, and the combustion exhaust gas from the upper nozzle 69 is guided to the center above the grill 24. . In addition, a lower inlet 44 which is opened in a circular shape facing the burner 60 is similarly provided at an intermediate position (a position lower than the grill 24) of the guide wall 37, and the flame of the horizontal nozzle 61 is transferred to the center of the grill storage 23. Department has been introduced.

Grill top plate 2 serving as ceiling surface of grill storage 23
7 is formed into two mountain shapes in which the central portion of the grill storage 23 is slightly lower, and
To the center of the In addition, far-infrared paint is applied. An air supply passage 29 is formed at the bottom of the grill storage 23, and opens to the guide wall 37 to communicate the combustion exhaust passage 41 with the center of the grill storage 23. A part of the air taken in from the air supply passage 29 is supplied to the burner 60, and the remaining air flows in the depth direction through the bottom of the grill storage 23, cools the tray 26, and is discharged together with the combustion exhaust gas.

With the above-described structure, the high-temperature combustion exhaust gas generated from the upper nozzle 69 of the burner 60 is
1, is guided by the guide wall 37 so as to rise to the vicinity of the grill top plate 27, flows through the upper inlet 42 to the upper portion of the grill storage 23, stays in the grill storage 23, and is directed toward the food F. Convection downward to heat the upper surface of the object to be cooked F. Moreover, the combustion exhaust gas introduced from the upper inlet 42 passes above the foods F placed on both right and left ends by the upper guide 43, and is cooled by the grill while maintaining high temperature without being cooled by them. The heat flows to the central portion of the heating device 24 and is sufficiently heated even for the object to be cooked F placed in the central portion which receives little heat because it is separated from the burner 60.

On the other hand, the flame from the horizontal nozzle 61 of the burner 60 is introduced into the lower surface of the grill 24 through the lower inlet 44 and directly heats the lower surface of the object F to be cooked. In this way, the combustion exhaust gas is positively guided to the upper central portion, and
The upper and lower surfaces can be simultaneously cooked evenly and simultaneously.

As described above, according to the double-sided grill 21 of the second embodiment, the following effects can be obtained in addition to the effects of the first embodiment. Since the guide wall 37 is erected above the grill 24 and the upper guide 43 is provided, the combustion exhaust gas flows from above to the center of the upper surface of the grill 24,
