The user opens and closes the door 30 with a handle so that the soup pan 29 and the grill 26 are moved to and out of the grill box 25.

Further, as shown in FIGS. 3 to 5, an inclined posture extending obliquely upward from the bottom side of the grill box 25 is provided at the center side portion in the lateral width direction of the exhaust side opening 25 a formed on the back side in the grill box 25. The exhaust path bottom portion forming wall portion 45 is provided.
And the front wall part 46 provided in the state which stood up from the bottom part side of the grill box 25 in the both sides of the width direction of the exhaust side opening 25a, the horizontal inward side edge part of the front wall part 46, and an exhaust path bottom part A horizontal wall portion 47 provided in an upright posture in a state of being connected to the lateral outer end portion of the forming wall portion 45, and a horizontal direction in a state of being connected to the upper end portion of the front wall portion 46 and the upper end portion of the horizontal wall portion 47. An exhaust passage lateral side wall portion 49 including an upper wall portion 48 provided in a posture extending in the direction is provided. Therefore, cooking exhaust generated in the heating chamber K can be efficiently guided from the heating chamber K to the exhaust path R.

  And the exhaust pipe 27 which forms the exhaust path R is connected to the upper end part 45a of the exhaust path bottom part forming wall part 45, the rear end part of the lateral wall part 47, and the lateral outer end part 48a of the upper wall part 48. An attachment portion 33 a provided on the lower end side of the lateral porous surface portion 33 in the flame extinguishing member 31 is attached to the upper wall portion 48. Thus, the flame extinguishing member 31 can be easily installed in the exhaust path R in a state where the side wall gap 36 is formed between the lateral side wall 27 c of the exhaust path R and the lateral porous surface portion 33 of the flame extinguishing member 31.

Next, the installation state in the inside of the exhaust path R of the flame-extinguishing member 31 and the flame-extinguishing member 31 is demonstrated.
As shown in FIG. 3, a flame extinguishing member 31 made of a porous material is provided inside the exhaust path R. The flame extinguishing member 31 is provided in the exhaust path R close to the grill box 25 side. As shown in FIG. 6, the flame-extinguishing member 31 is exhausted from the lateral end portions to the transverse porous surface portion 32 provided in a posture crossing the exhaust passage R and both lateral end portions of the transverse porous surface portion 32. And a lateral porous surface portion 33 provided in a state extending to the upstream side of the path R. Furthermore, a facing portion 41 having a facing surface 40 that is opposed to the upper side wall 27b of the exhaust passage R is provided at the upper end portions of the transverse porous surface portion 32 and the lateral porous surface portion 33 of the flame extinguishing member 31, and faces the upstream side of the exhaust passage R. It is formed in a frame having an exhaust introduction opening 34 that opens. That is, the flame extinguishing member 31 is formed as a polyhedron with the transverse porous surface portion 32 and the lateral porous surface portion 33. Thereby, the cooking exhaust gas including the flame introduced into the flame extinguishing member from the exhaust introduction opening 34 can be led out from the flame extinguishing member 31 through the transverse porous surface portion 32 and the lateral porous surface portion 33, so that the flow of cooking exhaust gas The flame contained in the cooking exhaust can be surely extinguished while reducing the resistance.

  As shown in FIGS. 4 and 5, the flame extinguishing member 31 is installed in a state in which a side wall gap 36 is formed between each lateral side wall 27 c that forms the exhaust path R facing both the lateral porous surface portions 33. ing. That is, since the width of the flame extinguishing member 31 is shorter than the length in the transverse direction of the exhaust passage R, when the flame extinguishing member 31 is installed at the center in the transverse direction of the exhaust passage R, both lateral porous surface portions 33 are disposed. And a side wall gap 36 is formed between each side wall 27c. Here, the width in the transverse direction of the exhaust passage R of each side wall gap 36 is configured to be substantially the same, for example, about 28 mm.

  As shown in FIG. 3, the flow resistance when the cooked exhaust flows through the side wall gap 36 is larger than the flow resistance when the cooked exhaust flows from the exhaust introduction opening 34 through the flame extinguishing member 31. Thus, the side wall gap length L1 which is the length along the longitudinal direction of the exhaust path R of the side wall gap 36 is set. Here, the exhaust path length L2 is set to a length that connects the vertical middle part of the exhaust side opening 25a and the middle part in the front-rear direction of the exhaust outlet 28 of the exhaust path R in a straight line, and the exhaust path R of the side wall gap 36 The side wall gap length L1 that is a length along the longitudinal direction of the exhaust gas R is such that a straight line parallel to a straight line indicating the length L2 of the exhaust path R intersects the lower end portion of the extinguishing member 31 on the exhaust side opening 25a side and the extinguishing member 31. The length connecting the porous surface portion 32 is used. In the example shown in FIG. 3, the side wall gap length L1 is about ½ of the exhaust path length L2, but the side wall gap length L1 is made shorter than this to make the side wall gap length L1. May be about 1/3 of the exhaust path length L2.

Thus, the side wall gap is such that the flow resistance when the cooked exhaust flows through the side wall gap 36 is greater than the flow resistance when the cooked exhaust flows from the exhaust introduction opening 34 through the flame extinguishing member 31. Since the length along the longitudinal direction of the exhaust path R of 36 is set, the cooked exhaust gas including the flame flowing out of the heating chamber K does not pass through the side wall gap 36, and as indicated by an imaginary line in FIG. In addition, the cooked exhaust can be introduced into the flame extinguishing member 31 through the exhaust introduction opening 34 and allowed to pass through the flame extinguishing member 31.

  Further, the width of each side wall gap 36 in the transverse direction of the exhaust passage R is about 28 mm as described above, but the resistance to flow when the cooked exhaust flows from the exhaust introduction opening 34 through the flame extinguishing member 31. Accordingly, the width of the side wall gap 36 can be increased or decreased.

Hereinafter, the flame extinguishing member 31 will be described in detail.
The flame extinguishing member 31 is formed by bending a single metal flat plate. The metal flat plate is, for example, an aluminum plated steel plate having a thickness of about 0.5 mm.
As shown in FIGS. 3 and 6, the transverse porous surface portion 32 of the flame extinguishing member 31 is an intermediate portion in the vertical direction perpendicular to the direction traversing the exhaust passage R in a state where the flame extinguishing member 31 is installed in the exhaust passage R. 39 is a bent portion, and the bent portion is formed in a bent shape positioned on the downstream side of the exhaust passage R. The transverse porous surface portion 32 has a plurality of slits 37 formed on the upper surface 32a above the intermediate portion 39 by cutting and raising, and a plurality of holes 38 are formed on the lower surface 32b below the intermediate portion 39. It is configured. A plurality of holes 38 are also formed in the lateral porous surface portion 33. The hole 38 is a circular hole having a diameter of 3 mm.

  The slit 37 is provided with a cooking exhaust guide piece 37a that guides the cooking exhaust that has passed through the slit 37 in a direction toward the upper side wall 27b of the exhaust path R. The slit 37 and the cooking exhaust guide piece 37a are formed by cutting and raising processing. That is, the slit 37 is a cut and raised hole, and is a cooking exhaust guide piece 37a cut and raised piece.

  Further, the flame extinguishing member 31 is provided with a protrusion 42. The protrusions 42 are provided so as to extend from both ends of the lower surface 32b in the transverse direction of the exhaust path R toward the lower side wall 27a in a state parallel to the lateral side wall 27c of the exhaust tube 27. The protrusion 42 can keep the flame extinguishing member 31 and the lower side wall 27a of the exhaust tube 27 apart from each other, and the formation of the gap 50 is maintained (see FIG. 3). Further, as described above, the bottom of the exhaust path R is configured by the lower wall 27a of the exhaust tube 27 and the exhaust path bottom forming wall 45, and covers the entire area from the exhaust outlet 28 to the connection to the grill box 25. The inclined posture is such that it is positioned downward as it approaches the grill box 25. Thereby, when a foreign object falls and enters from the exhaust outlet 28, it passes through the gap 50 and falls to the grill box 25, so that the exhaust path R can be prevented from being blocked by the foreign object.

  The exhaust outlet 28 in the exhaust path R is provided with a porous dustproof member 35 having a large number of vent holes 35a. In other words, the dust-proof member 35 is formed of a lath net, which is a wire net having a large number of ventilation holes 35a, and is provided in a state of covering the entire area of the opening of the exhaust outlet 28 in the exhaust path R. ing. In the lath net, the size (mesh size) of each air hole 35a is set to 12 mm × 6 mm so that the exhaust resistance is not increased and the cooked exhaust is well exhausted to the outside.

  According to the above configuration, the flame extinguishing member 31 is installed in a state where the side wall gap 36 is formed between the lateral side wall 27c of the exhaust passage R, so that the dimension of the flame extinguishing member 31 is matched to the transverse dimension of the exhaust passage R. Therefore, it is not necessary to process with high accuracy, and the manufacturing cost of the gas stove can be reduced and the manufacturing can be facilitated. Then, in the heating chamber K, when the cooking object N such as fish placed on the grill 26 is heated, the oil generated from the cooking object N is ignited and a flame is generated. May flow into the exhaust path R together with the cooking exhaust, at that time, the cooking exhaust does not pass through the side wall gap 36 but is introduced into the flame extinguishing member 31 from the exhaust introduction opening 34 and passes through the flame extinguishing member 31. Thus, the flame contained in the cooking exhaust can be extinguished by the flame extinguishing action of the flame extinguishing member 31.
