The gas supply port 662 is provided with an enlarged diameter at an upstream end of the gas supply path 661. A gas supply pipe (not shown) is connected to the gas supply port 662. Thus, the gas flows from the gas supply pipe to the gas supply path 661 via the gas supply port 662, and is supplied to the grill burner 65.

  The exhaust port 67 is provided behind the gas supply unit 66. The exhaust port 67 is provided with a substantially rectangular exhaust port 671 that is long in the left-right direction in plan view. The exhaust port 671 extends vertically. An exhaust pipe (not shown) is connected to the exhaust port 67. The exhaust pipe extends obliquely upward with respect to the rear, and its open upper end is disposed immediately below an exhaust port 11 (see FIG. 1) provided on the rear end side of the top plate 3. Thus, the combustion gas generated in the grill unit 40 flows into the exhaust pipe via the exhaust port 671 and is discharged from the exhaust port 11 to the outside.

  As shown in FIGS. 3 to 6, on the left side of the lower surface of the hood main body 61 having the above structure, in the vicinity of the through hole 69 </ b> A of the wall 69, the periphery excluding the tip of the thermocouple 71 is provided. A shielding cover 80 for covering and protecting is fixed. The shielding cover 80 is formed, for example, by bending a thin metal plate into a substantially U-shape. As the thin plate forming the shielding cover 80, for example, a steel plate having a thickness of less than 3 mm can be used, but the thickness may be changed according to the material or the like. In addition, as described later, in order to increase the temperature of the shielding cover 80, it is preferable to use a steel plate of 1 mm or less.

  Here, in the grill unit 40, the combustion gas generated by the gas combustion in the grill burner 65 flows backward toward the exhaust port 67 side. Therefore, as shown in FIGS. 5 and 6, in the vicinity of the thermocouple 71, the combustion gas flows toward the front side of the thermocouple 71, but in the present embodiment, the surroundings of the thermocouple 71 except for the tip end portion are covered. Cover 80 is provided as described above. Thus, the combustion gas flowing toward the thermocouple 71 collides with the shielding cover 80 and changes its direction to the grill burner 65 side. That is, since the flow of the combustion gas changes, soot contained in the combustion gas can be prevented from adhering to the thermocouple 71.

  In addition, since the shielding cover 80 of the present embodiment is formed of a thin plate having a thickness of 1 mm or less in the vicinity of the left flame hole 652 of the grill burner 65, the temperature of the shielding cover 80 can be increased. Thereby, the soot attached to the outer surface of the shielding cover 80 can be burned off. Further, since the shielding cover 80 is provided so as to be bent in a substantially U-shaped cross section so as to surround the periphery of the portion other than the distal end portion of the thermocouple 71, for example, when cleaning, the worker attaches the shielding cover 80 to the operator. There is no risk of injury even if the hand hits.

  As described above, the stove 1 of the present embodiment includes the grill unit 40 that heats and cooks an object to be cooked. The grill unit 40 includes a unit main body 50 and a grill hood 60 fixed to an upper portion thereof. The grill hood 60 is provided with a grill burner 65. The flame hole 650 of the grill burner 65 is arranged inside the grill unit 40. In the grill hood 60, a thermocouple 71 is provided so as to protrude toward the left flame hole 652 side of the grill burner 65 at the tip. An exhaust port 671 is provided at the rear of the grill unit 40. The exhaust port 671 discharges the combustion gas generated in the grill unit 40 to the outside. In such a grill unit 40, a shielding cover 80 is provided so as to surround the periphery of the thermocouple 71 except for the distal end portion. When the combustion gas flowing toward the exhaust port 671 collides with the shielding cover 80, the flow changes, so that the soot contained in the combustion gas can be prevented from adhering to the thermocouple 71. Therefore, when the user cleans the inside of the grill unit 40, the user does not get dirty even if the hand hits the thermocouple 71, so that usability can be improved.

  In the above description, the grill unit 40 shown in FIG. 2 is an example of the “grill storage” of the present invention. The exhaust port 671 of the exhaust port 67 shown in FIG. 3 is an example of the “exhaust port” of the present invention. The shielding cover 80 shown in FIG. 6 is an example of the “shielding member” of the present invention.

  Note that the present invention is not limited to the above-described embodiment, and various modifications are possible. In the above-described embodiment, the stove 1 includes the grill unit 40 therein. However, the stove 1 is not limited to the stove as long as the stove 1 includes the grill unit 40, and may be another cooking device. For example, the present invention is also applicable to a grill device mainly including the grill unit 40.

  In addition, the stove 1 of the present embodiment includes two stove burners 4 and 5 on the top plate 3, but the number of stove burners may be one or more. Further, the right rear stove burner 4 is a standard burner, and the left front stove burner 5 is a high heat burner. For example, both may be a standard burner or a high heat burner.

  Further, the shielding cover 80 of the present embodiment is formed to be bent in a substantially U-shaped cross section so as to surround the thermocouple 71, but at least the side opposite to the exhaust port 671 side of the thermocouple 71. The shape of the shielding cover 80 is not limited as long as it can be covered. For example, it can be provided in the form of a tube, and in that case, it may be any of a cylindrical shape and a rectangular tube shape. Further, a flat shielding cover extending in the vertical direction may be provided at a position opposite to the exhaust port 671 side of the thermocouple 71. Even in such a case, the opposite side of the thermocouple 71 from the exhaust port 671 side can be covered, so that the soot can be prevented from adhering to the thermocouple 71 as in the above embodiment.

  In the above embodiment, the grill hood 60 is provided with the grill burner 65, but a grill burner may be provided on the unit body 50 side. Also in that case, the shielding cover may be provided so as to cover at least the side opposite to the exhaust port 671 side in the portion excluding the tip of the thermocouple.

  Further, although the flame hole portion 650 of the grill burner 65 of the above embodiment is formed in a substantially U-shape when viewed from the bottom, it may have another shape, for example, a substantially rectangular shape.
