With such a configuration, the exhaust gas in the first exhaust pipe 32 and the first exhaust pipe 32 can be cooled. A suction port 333 for taking in outside air is opened at the lower part of the second exhaust pipe 33.

  The upper end of the exhaust tower 3 is preferably inclined obliquely forward, and the exhaust ports 327 and 337 of the first exhaust pipe 32 and the second exhaust pipe 33 are preferably opened obliquely forward. By adopting such a configuration, it is possible to discharge the combustion exhaust gas or air that has risen upward in the first exhaust pipe 32 and the second exhaust pipe 33 in the diagonally upper front direction of the gas stove 1. However, even when the exhaust tower 3 is installed in contact with the wall surface of the cooking area, heating of the wall surface by the combustion exhaust gas can be suppressed.

  Moreover, it is preferable to form the pan stopper 39 which protrudes in the front direction of the gas stove 1 on the front wall 30 of the exhaust tower 3. The pan stopper 39 is a stopper for forming a space Z between the rear back surface 303 of the pan 300 and the front surface portion 51 of the guard 5 when the pan 300 is installed on the gas stove 1. By setting it as such a structure, the combustion gas which flowed out of the stove main body 10 through the notch recessed part 62 from the combustion chamber 2 can heat the back rear surface 303 of the pan 300 reliably.

  Further, it is preferable to provide a rectifying plate 38 that is inclined diagonally forward of the gas stove 1 across both ends of the front wall 30 at the upper portion of the front wall 30 of the exhaust tower 3. The rectifying plate 38 flows from the combustion chamber 2 through the notch recess 62 and flows to the outside of the stove body 10, and the flow direction of the combustion exhaust gas rising upward in the space Z between the pan 300 and the guard 5 is defined as a gas stove. 1 is a plate for changing in a diagonally upper front direction. By setting it as such a structure, the heating of the front wall 30 of the exhaust pipe 3 by combustion exhaust gas can be suppressed.

  Next, the use, operation, and action of the gas stove 1 will be described. First, a pan 300 such as a small pan is placed on Gotoku 6. At this time, the pan 300 is moved to the back side until the pan stopper 39 stops its movement. In addition, the upper surface 61 of Gotoku 6 and the bottom surface 309 of the pan 300 are in contact with each other and no gap is generated. By installing in this way, the space Z can be formed between the rear back surface 303 of the pan 300 and the front surface portion 51 of the guard 5, and the rear back surface 303 of the pan 300 can be surrounded by the guard 5.

  And, if necessary, the ingredients are introduced into the pan 300. When water is introduced, the water supply cock 82 provided on the front surface of the operation box 4 is operated, and the water supply currant 81 provided on the upper surface of the operation box 4 is operated. Can give water. Next, the power switch 83 and the ignition switch 84 are pressed to ignite the gas burner 20.

  When the gas burner 20 is ignited, the air in the combustion chamber 2 is heated to become combustion gas and rises. As this rises, as shown by the arrow B in FIG. Intake into the combustion chamber 2 to supply combustion gas. The combustion gas in the combustion chamber 2 hits the bottom surface 309 of the pan 300 and heats the pan 300 and the ingredients in the pan 300. The combustion gas heats the pan 300 to become combustion exhaust gas, and a part of the combustion exhaust gas flows into the first exhaust pipe 32 through the exhaust pipe 31 as indicated by arrows C1 to C3 in FIG. C1) Ascends in the first exhaust pipe 32 (C2), and is discharged to the outside from the exhaust port 327 of the first exhaust pipe 32 (C3).

  On the other hand, the remaining portion of the combustion exhaust gas that heated the pan 300 flows into the space U between the bottom surface 309 of the pan 300 and the notch recess 62 as shown by arrows D1 to D3 in FIG. It is discharged outside from between. Specifically, the combustion exhaust gas flowing from the combustion chamber 2 to the notch recess 62 moves in the horizontal direction between the virtues 6 and the pan 300 and is guided upward by the protrusion 66 (D1). The rear surface 303 of the pan 300 is heated while ascending the space Z between 51 and the rear surface 303 of the pan 300 along the pan 300 (D2). And the combustion exhaust gas which rises just above after heating the back rear surface 303 of the pan 300 collides with the current plate 38 as shown by an arrow D3 in FIG. (D3).

  Further, the combustion exhaust gas flows into the notch recess 62 and is discharged to the outside from between the virtues 6 and the pan 300, and as shown by arrows E1 and E2 in FIG. Unheated external air is sucked into the front portion 51 of the guard 5 from the gaps between the side portion 52 and the intermediate portion 53 of the guard 5 and the pan 300 and rises together with the combustion exhaust gas. For this reason, combustion exhaust gas does not flow out to the front side through the periphery of the pan 300, and it is possible to prevent the top plate 12, the guard 5, the air, etc. in front of the pan 300 from being heated.

  Also, as shown by arrows F1 and F2 in FIGS. 1 and 7, the air flowing into the space X between the inner wall 21 and the outer wall 22 from the gap S between the suction tube 201 and the insertion hole 221 passes through the inner wall 21 and the outer wall 22. It is cooled and flows from the gap T between the exhaust pipe 31 and the exhaust hole 222 to the first exhaust pipe 32 and is mixed with the combustion exhaust gas that has flowed into the first exhaust pipe 32 through the exhaust pipe 31. Cool the gas.

  Further, as indicated by arrows G1 to G5 in FIG. 1, from the air (G1) flowing into the stove main body 10 from the air port 161 of the front plate 16 and the opening 176 in the lower separation portion of the front plate 16 and the front plate 17. The inflowing air (G2) cools the front plate 17 and the front plate 16, passes through the air inlet 171 (G3), flows into the space Y between the top plate 12 and the intermediate wall 15 (G4), and is outside the outer wall 22. The top plate 12 is mainly cooled through and flows to the exhaust tower 3, more specifically, the second exhaust pipe 33 (G5).

  Further, due to the rise of the combustion exhaust gas in the first exhaust pipe 32, the heating of the first exhaust pipe 32, and the action of the air flowing in from the space Y and rising in the second exhaust pipe 33, arrows H1 to H3 in FIG. As shown in the drawing, external air is sucked from the suction port 333 of the second exhaust pipe 33 (H1), mixed with the air flowing in from the space Y and rising in the second exhaust pipe 33, and the first exhaust pipe 32 and the first exhaust pipe 33. The combustion exhaust gas in one exhaust pipe 32 is cooled and rises (H2), and is discharged to the outside from the exhaust port 337 of the second exhaust pipe 33 (H3).

  When the combustion exhaust gas or air that has risen through the first exhaust pipe 32 and the second exhaust pipe 33 is discharged from the exhaust ports 327 and 337 to the outside, the exhaust ports 327 of the first exhaust pipe 32 and the second exhaust pipe 33 are used. Since 337 is opened obliquely forward, the gas stove 1 can be discharged obliquely upward in the forward direction.

  Thus, the combustion exhaust gas is used for heating the pan 300, the heating of the gas stove 1, especially the top plate 12 and the front of the gas stove by the combustion exhaust gas heating the pan 300, various air By cooling each part of the gas stove 1 and the combustion exhaust gas by this flow, the object of the present invention of preventing the gas stove from overheating and improving the heating efficiency of the pan can be achieved.

  While the gas is burned by the gas burner 20, the above action is continuously performed. When cooking of the ingredients in the pan 300 is completed, the gas burner 20 is extinguished by pressing the power switch 83 provided on the front surface of the operation box 4 on the front surface of the gas stove 1.

  In this way, all operations can be performed on the front surface of the gas stove 1, without placing a part of the body above the pan 300 and without bringing the face close to the pan 300, thus improving worker safety. The object of the present invention to ensure can be achieved.

  In addition, as mentioned above, although the gas stove of this invention was demonstrated by the double type which can cook two pots simultaneously, the gas stove of this invention is a series which can cook only one pot 300, as shown in FIG. It may be a gas stove 99 of the formula. In the case of such a configuration, the guard 5 is constituted by a semicircular front part 51 and a straight side part 52 in a plan view, and is substantially n-shaped. In addition, the guard 5 may be comprised only by the semicircular arc-shaped front part 51 by planar view, without providing a side part.

  As another embodiment of the gas stove, as shown in FIG. 10, the exhaust tower 3 of the gas stove 91 covers the back surface portion 93 of the second exhaust pipe 33 and opens a suction port 393 for taking outside air into the lower portion.
