As shown in FIGS. 11 and 12, the right duct portion 72 includes a front side case portion 73, a rear side case portion 74, and a right cooling fan 75. The front case portion 73 includes a main body portion 731 and a front flow path forming portion 732. The main body 731 is formed in a substantially rectangular shape when viewed from the rear, and has substantially the same shape as the opening on the rear end side of the rear tubular portion 92 of the right front panel 90. A fixing hole 736 is provided at the upper right corner of the main body 731 and adjacent to the right side surface of the front flow path forming portion 732 described later. The fixing hole 736 corresponds to the fixing hole 931 on the right side of the fixing plate 93 of the right front panel 90. An insertion tube portion 735 projecting forward is provided on the lower side of the front surface of the main body portion 731. The insertion tube portion 735 is formed in a substantially square tube shape. Therefore, the main body portion 731 is arranged so as to project outward from the rear end of the insertion cylinder portion 735 and surround the periphery of the insertion cylinder portion 735.

The front flow path forming portion 732 is inclined slightly to the right from the lower part of the back surface of the main body portion 731 and extends upward, and further protrudes upward from the upper end portion of the main body portion 731. The cross section of the front flow path forming portion 732 orthogonal to the length direction is a substantially U-shape that opens rearward. A fixing piece 737 projecting to the left is provided on the left side surface of the portion of the front flow path forming portion 732 projecting upward. The fixing piece 737 is provided with a fixing hole (not shown) penetrating in the front-rear direction. A fan fixing portion 734 is provided at the lower end portion of the front flow path forming portion 732. The fan fixing portion 734 has a substantially rectangular shape in the rear view, and is formed in a substantially box shape that opens toward the rear. An insertion hole 733 for inserting in the front-rear direction is provided on the inner surface of the main body portion 731 and inside the fan fixing portion 734. The insertion hole 733 is formed in a substantially circular shape in the rear view. The insertion hole 733 communicates with the inside of the insertion cylinder portion 735. Further, a fixing hole 738 is provided inside the fan fixing portion 734 and in the vicinity of the upper left of the insertion hole 733. The fixing hole 738 corresponds to the fixing hole 931 on the left side of the fixing plate 93 of the right front panel 90.

The rear case portion 74 includes a lid-shaped portion 741 and a rear flow path forming portion 742. The lid-shaped portion 741 is provided below the rear case portion 74. The lid-shaped portion 741 has substantially the same shape as the fan fixing portion 734 of the front side case portion 73, and is formed in a substantially box shape that opens toward the front. A notch 743 formed in a substantially rectangular shape is provided in the lower left portion of the lid-shaped portion 741. The rear flow path forming portion 742 has a shape corresponding to the front flow path forming portion 732 of the front case portion 73, and is slightly inclined to the right and extends upward from the upper portion of the lid-shaped portion 741. The cross section of the rear flow path forming portion 742 orthogonal to the length direction is a substantially U-shape that opens toward the front.

The right cooling fan 75 is fixed to the inside of the fan fixing portion 734 of the front side case portion 73 from the rear. The air suction port (not shown) of the right cooling fan 75 is arranged on the insertion hole 733 side. The air outlet (not shown) of the cooling fan is arranged upward toward the front flow path forming portion 732. The rear case portion 74 is attached from the rear to the front case portion 73 in which the right cooling fan 75 is fixed to the fan fixing portion 734, and is fixed by a plurality of screws. As a result, the right duct portion 72 is configured. Inside the front flow path forming portion 732 and the rear flow path forming portion 742, an air flow path is formed in which the air sucked by the right cooling fan 75 flows from the lower side to the upper side. A substantially rectangular outlet 721 is provided at the upper end of the right duct portion 72. The outflow port 721 opens upward and serves as an outlet for the air flow path of the right duct portion 72.

Then, as shown in FIG. 13, in the right duct portion 72, the harness 751 of the right cooling fan 75 fixed to the fan fixing portion 734 is pulled out from the rectangular opening 744 formed by the notch portion 743. Is done. The opening 744 is then closed by the outer surface of the casing 750 of the right cooling fan 75. The peripheral edge of the opening 744 and the outer surface of the casing 750 are in close contact. As a result, the stove 1 can prevent the intrusion of high-temperature air into the air flow path inside the right duct portion 72 while maintaining the electrical connection of the right cooling fan 75.

Although not described in detail, the structure of the left duct portion 71 is the same as that of the right duct portion 72. A left cooling fan (not shown) is attached to the inside of the left duct portion 71, and an air flow path through which the air sucked by the left cooling fan flows from the lower side to the upper side is formed. A substantially rectangular outlet 711 (see FIG. 6) is provided at the upper end of the left duct portion 71. The outflow port 711 opens upward and serves as an outlet for the air flow path of the left duct portion 71.

An example of a method of fixing the right duct portion 72 to the right front panel 90 will be described with reference to FIG. The main body 731 of the front case 73 of the right duct 72 is positioned so as to close the opening from the rear with respect to the opening on the rear end side of the rear tubular 92 of the right front panel 90. The rear opening end of the rear tubular portion 92 and the fixing plate 93 are in close contact with the front surface of the main body portion 731. As a result, the opening on the rear end side of the rear tubular portion 92 is closed by the main body portion 731.

Further, the insertion cylinder portion 735 of the right duct portion 72 is fitted and connected to the inside of the rear end opening 952 of the intake passage portion 95 of the right front panel 90. The rear end opening 952 is in close contact with the front surface of the main body 731. The protruding portion 953 is in close contact with the front surface of the main body portion 731 (see FIG. 9). At this time, the fixing hole 738 inside the fan fixing portion 734 of the right duct portion 72 faces the fixing hole 931 on the left side of the fixing plate 93 of the right front panel 90, and is fixed with screws. The fixing hole 736 near the upper right corner of the main body 731 of the right duct portion 72 faces the fixing hole 931 on the right side of the fixing plate 93 of the right front panel 90, and is fixed with screws. Then, at a plurality of other places, the right duct portion 72 is fixed to the right front panel 90 with a plurality of screws. As a result, the intake passage portion 95 of the right front panel 90 and the air flow path inside the right duct portion 72 communicate with each other. Therefore, an intake duct extending from the air inlet 951 of the intake passage portion 95 to the outlet 721 of the right duct portion 72 is formed.

In this way, the insertion cylinder portion 735 of the right duct portion 72 is fitted and connected to the inside of the rear end opening 952 of the intake passage portion 95 of the right front panel 90, and further surrounds the insertion cylinder portion 735. Since the front surface of the main body 731 of the right duct portion 72 and the opening on the rear end side of the rear cylinder portion 92 of the right front panel 90 are in close contact with each other, the insertion cylinder portion 735 is doubly airtight.

Further, the fixing hole of the fixing piece 737 of the right duct portion 72 is positioned with respect to the fixing hole 941 of the support pillar 94 protruding rearward from the back surface of the main body portion 91A of the right front panel 90, and the screw is fastened. As a result, the portion of the right duct portion 72 that protrudes upward is firmly supported by the support pillar 94 of the right front panel 90. Since the structure for fixing the left duct portion 71 to the left front panel 80 is the same as the structure for fixing the right duct portion 72 to the right front panel 90, the description thereof will be omitted.

An example of a method of connecting the left cylinder portion 42 and the right cylinder portion 43 of the sensor case 40 to the left duct portion 71 and the right duct portion 72 will be described with reference to FIGS. 6 and 11. The top plate 3 is placed so as to close the upper opening of the housing 2. At this time, as shown in FIG. 6, the intake 421 of the left cylinder portion 42 of the sensor case 40 fixed to the lower surface of the top plate 3 is positioned at the outlet 711 of the left duct portion 71, and is an elastic body 422 (FIG. 6). 8) to connect closely. As a result, the intake passage portion 85 of the left front panel 80, the air passage portion in the left duct portion 71, and the inside of the left cylinder portion 42 of the sensor case 40 can be communicated with each other. On the other hand, the intake 431 of the right cylinder portion 43 is positioned at the outlet 721 of the right duct portion 72, and is closely connected via the elastic body 432 (see FIG. 8). As a result, the intake passage portion 95 of the right front panel 90, the air passage portion in the right duct portion 72, and the inside of the right cylinder portion 43 of the sensor case 40 can be communicated with each other. In this state, the top plate 3 is fixed to the upper opening of the housing 2 with screws.

With reference to FIGS. 5 to 8, the flow until the air sucked from the air inlets 851 and 951 of the intake passages 85 and 95 is supplied to the sensor case 40 will be described. When the grill 10 is used on the stove 1, the temperature around the grill 10 rises. Therefore, it is preferable to cool the electrical board 100 housed in the sensor case 40 and the nine sensors 31 to 39. Therefore, the control unit of the stove 1 drives both the left cooling fan in the left duct portion 71 and the right cooling fan 75 in the right duct portion 72.

When the left cooling fan in the left duct portion 71 is driven, external air is sucked into the intake passage portion 85 from the air inlet 851 at the lower front side of the left front panel 80. Since the air inlet 851 is opened downward in the vicinity of the bottom surface of the housing 2, it is possible to effectively prevent the high temperature air around the grill chamber 10 from being sucked into the intake passage portion 85. The air sucked into the intake passage portion 85 flows rearward in the intake passage portion 85 as cooling air supplied toward the sensor case 40. The cooling air exits from the rear end opening (not shown) of the intake passage portion 85 and flows upward in the left duct portion 71. The cooling air that has flowed through the left duct portion 71 flows inward from the intake 421 of the left cylinder portion 42 of the sensor case 40.

When the right cooling fan 75 in the right duct portion 72 is driven, external air is sucked into the intake passage portion 95 from the air inlet 951 at the lower front side of the right front panel 90. Since the air inlet 951 also opens downward in the vicinity of the bottom surface of the housing 2, it is possible to effectively prevent the high temperature air around the grill chamber 10 from being sucked into the intake passage portion 95. Further, as described above, the insertion cylinder portion 735 of the right duct portion 72 is fitted and connected to the inside of the rear end opening 952 of the intake passage portion 95 of the right front panel 90, and the main body portion 731 of the right duct portion 72 is connected. Since the front surface of the right front panel 90 and the opening on the rear end side of the rear cylinder portion 92 of the right front panel 90 are in close contact with each other, the insertion cylinder portion 735 of the right duct portion 72 is doubly airtight. Thereby, for example, it is possible to effectively prevent the high temperature air in the housing 2 from flowing forward through the rear cylinder portion 92 of the right front panel 90 and being sucked into the air inlet 951. Further, it is possible to prevent the high temperature air in the housing 2 from being sucked into the right duct portion 72 through the gap of the fan fixing portion 734. This configuration is the same on the left front panel 80 side.

Then, the air sucked into the intake passage portion 95 flows backward in the intake passage portion 95 as cooling air supplied toward the sensor case 40. The cooling air exits from the rear end opening 952 of the intake passage portion 95 and flows upward in the right duct portion 72. The cooling air that has flowed through the right duct portion 72 flows inward from the intake 431 of the right cylinder portion 43 of the sensor case 40.

Here, as shown in FIG. 10, when the operation unit 9 is pulled out to the front side in the right front panel 90, the upper end side of the decorative plate 6D fixed to the front surface of the operation unit 9 is tilted forward. It becomes an inclined state and is separated forward from the air inlet 951 of the intake passage portion 95. In this case, sufficient air can be taken in from the air inlet 951. On the other hand, as shown in FIG. 9, when the operation unit 9 is housed in the frame portion 91B of the right front panel 90, the decorative plate 6D is in a vertical standing posture, so that the intake passage portion 95 The front side of the air inlet 951 is closed. However, since the pair of inclined portions 96 are arranged on the left and right sides of the air inlet 951, the air is sufficiently taken in from the lateral direction through the gap formed between the decorative plate 6D and the pair of inclined portions 96. be able to. Further, regardless of the posture of the operation unit 9, the air inlet 951 is opened downward and is not blocked by the decorative plate 6D. Therefore, the stove 1 can sufficiently take in air from the air inlet 951 into the intake passage portion 95.

The flow of cooling air in the sensor case 40 will be described with reference to FIGS. 7 and 8. The cooling air that has flowed into the left cylinder portion 42 is divided into the lower surface side and the upper surface side of the main body portion 41 at a predetermined ratio by the left inflow inlet 52 provided in the front protruding portion 611. On the other hand, the cooling air flowing into the right cylinder portion 43 is also divided into the lower surface side and the upper surface side of the main body portion 41 at a predetermined ratio by the right inflow inlet 53 provided in the front protruding portion 621. In the present embodiment, the electrical substrate 100 and the sensors 31 to 39 have different heat resistances, so that the ratio of the cooling air to the lower surface side and the upper surface side of the main body 41 is optimized so that the left inflow inlet is optimized. It is advisable to adjust the opening area of each of the 52 and the right inflow port 53.

The flow of the cooling air diverted to the lower surface side of the main body 41 will be described. As shown in FIG. 8, the cooling air flowing from the inside of the left cylinder portion 42 to the lower surface side of the main body portion 41 flows into the sensor accommodating portion 60 provided on the lower surface side of the rear side portion 45 from the left end side. The cooling air flows through the left sensor path 60A of the sensor accommodating portion 60 from the left end side toward the center side. As a result, the sensors 31 to 35 are cooled by the cooling air. The cooling air flowing to the center side through the left side sensor path 60A flows out to the outside through the connection cylinder 68 provided in the central lid portion 653. On the other hand, the cooling air flowing from the inside of the right cylinder portion 43 to the lower surface side of the main body portion 41 flows into the sensor accommodating portion 60 from the right end side. The cooling air flows through the right sensor path 60B of the sensor accommodating portion 60 from the right end side toward the center side. As a result, the sensors 36 to 39 are cooled by the cooling air. The cooling air flowing to the center side through the right sensor path 60B flows out to the outside through the connection cylinder 68 provided in the central lid portion 653. Since the elastic body 69 attached to the lower end of the connection cylinder 68 is in close contact with the peripheral edge of the through port 271 of the heat shield plate 27, the cooling air is prevented from leaking to the outside through the gap between the connection cylinder 68 and the through port 271. Can be prevented.

Then, the cooling air flowing out through the connecting cylinder 68 flows backward through the gap between the heat shield plate 27 and the upper wall 101 of the grill storage 10 (see FIG. 3). As a result, it is possible to prevent high-temperature air from staying in the gap between the heat shield plate 27 and the upper wall 101 of the grill storage 10, so that the temperature rise of the top plate 3 can be suppressed. The cooling air that has flowed backward through the gap flows into the duct portion 28, and is discharged to the outside from the grill exhaust port 281 and the exhaust port 7 together with the combustion exhaust from the grill storage 10.

The flow of the cooling air divided on the upper surface side of the main body 41 will be described. As shown in FIG. 7, the cooling air that has flowed from the inside of the left cylinder portion 42 to the upper surface side of the rear side portion 45 via the left inflow inlet 52 of the front protrusion portion 611 flows into the substrate accommodating portion 50 from the left end side. .. The cooling air flows along the left substrate path 50A of the substrate accommodating portion 50 from the left end side toward the center side. As a result, the left half of the electrical board 100 is cooled by the cooling air. The cooling air flowing to the center side through the left substrate path 50A is discharged to the outside from the front discharge port 54A. On the other hand, the cooling air that has flowed from the inside of the right cylinder portion 43 to the upper surface side of the rear side portion 45 through the right inflow inlet 53 of the front protrusion portion 621 flows into the substrate accommodating portion 50 from the right end side. The cooling air flows along the right substrate path 50B of the substrate accommodating portion 50 from the right end side toward the center side. As a result, the right half of the electrical board 100 is cooled by the cooling air. The cooling air flowing to the center side through the right substrate path 50B is discharged to the outside from the front discharge port 54B. Here, the handle 8A of the grill door 8 is located below the front discharge ports 54A and 54B. The cooling air discharged from the front discharge ports 54A and 54B flows toward the handle 8A. As a result, the handle 8A is cooled by the cooling air, so that the temperature rise can be suppressed.

As described above, the stove 1 of the above embodiment includes a housing 2, a left front panel 80, a right front panel 90, a grill storage 10, a top plate 3, and a sensor case 40.

The intake passage portion 95 allows the cooling air sucked from the front side to flow backward. The rear end opening 952 of the intake passage portion 95 is fitted and connected to the insertion cylinder portion 735 of the right duct portion 72. Further, the main body portion 731 of the right duct portion 72 is closely fixed to the rear end portion of the rear tubular portion 92 of the front wall portion 91 so as to surround the intake passage portion 95. As a result, the insertion cylinder portion 735 is doubly airtight, so that it is possible to prevent the hot air in the housing 2 from entering the right duct portion 72.
