A notch portion 743 formed in a substantially rectangular shape is provided in the lower left portion of the lid-like portion 741 . The rear flow passage forming portion 742 has a shape corresponding to that of the front flow passage forming portion 732 of the front case portion 73 and extends upward from the upper portion of the lid-shaped portion 741 while being slightly rightwardly inclined. A cross section perpendicular to the length direction of the rear flow path forming portion 742 is substantially U-shaped opening forward.

The cooling fan 75 is attached inside the fan attachment portion 734 of the front case portion 73 from behind. An air suction port (not shown) of the cooling fan 75 is arranged on the insertion hole 733 side. An air blowing port (not shown) of the cooling fan is arranged upward toward the front flow passage forming portion 732 . The rear case portion 74 is attached from the rear to the front case portion 73 having the cooling fan 75 attached to the fan attachment portion 734 and is fixed with a plurality of screws. The right duct portion 72 is thus configured. Inside the front channel forming portion 732 and the rear channel forming portion 742, an air channel is formed through which the air sucked by the cooling fan 75 flows upward. An outflow port 721 is provided at the upper end portion of the right duct portion 72 . The outflow port 721 opens upward and serves as the outlet of the air flow path of the right duct portion 72 .

In the right duct portion 72 , the harness (not shown) of the cooling fan 75 attached to the fan attachment portion 734 is pulled out from a rectangular opening (not shown) formed by the notch portion 743 . This opening is closed by the outer surface of the casing of the cooling fan 75 . The periphery of the opening and the outer surface of the casing are in close contact. As a result, the stove 1 can prevent high-temperature air from entering the air flow path inside the right duct portion 72 while maintaining the electrical connection of the cooling fan 75 .

Although not described in detail, the structure of the left duct portion 71 is also the same as the structure of the right duct portion 72 . A cooling fan (not shown) is mounted inside the left duct portion 71, and an air flow path is formed through which air sucked by the cooling fan flows upward from below. An 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 the outlet of the air flow path of the left duct portion 71 .

An example of a method for fixing the right duct portion 72 to the right front panel 90 will be described with reference to FIG. 11 . The body portion 731 of the front case portion 73 of the right duct portion 72 is positioned with respect to the rear end side opening of the rear cylindrical portion 92 of the right front panel 90 so as to close the opening from behind. The open end on the rear end side 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 tube portion 735 of the right duct portion 72 is fitted inside the rear end opening portion 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 body portion 731 . The projecting portion 953 is in close contact with the front surface of the main body portion 731 (see FIG. 9). In this state, the right duct portion 72 is fixed to the right front panel 90 with a plurality of screws. As a result, the air 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. Accordingly, 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 manner, the insertion cylinder portion 735 of the right duct portion 72 is fitted inside the rear end opening 952 of the intake passage portion 95 of the right front panel 90 , and the right duct portion 72 is mounted so as to surround the insertion cylinder portion 735 . and the opening of the rear cylindrical portion 92 of the right front panel 90 are in close contact with each other, so that the insertion cylindrical 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 column 94 projecting rearward from the back surface of the main body portion 91A of the right front panel 90, and screws are tightened. As a result, the portion of the right duct portion 72 that protrudes upward is firmly supported by the support column 94 of the right front panel 90 . 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, so description thereof will be omitted.

An example of a method of connecting the left tubular portion 42 and the right tubular portion 43 of the sensor case 40 and 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 block the upper opening of the housing 2 . At this time, as shown in FIG. 6, the intake port 421 of the left tubular portion 42 of the sensor case 40 fixed to the lower surface of the top plate 3 is positioned at the outlet port 711 of the left duct portion 71, and the elastic body 422 ( 8) to make a tight connection. As a result, the air intake passage portion 85 of the left front panel 80, the air flow path in the left duct portion 71, and the inside of the left cylindrical portion 42 of the sensor case 40 can be communicated with each other. On the other hand, the intake port 431 of the right cylindrical portion 43 is positioned at the outlet port 721 of the right duct portion 72 and closely connected via an elastic body 432 (see FIG. 8). As a result, the intake passage portion 95 of the right front panel 90, the air flow path in the right duct portion 72, and the inside of the right cylindrical 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.

5 to 8, the flow of the air sucked from the air inlets 851, 951 of the air intake passages 85, 95 to the sensor case 40 will be described. In the stove 1, the temperature around the grill 10 rises when the grill 10 is used. 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 section of the stove 1 drives both the cooling fan in the left duct section 71 and the cooling fan 75 in the right duct section 72 .

When the cooling fan in the left duct portion 71 is driven, outside air is sucked into the air intake passage portion 85 from the air inlet 851 at the front lower portion of the left front panel 80 . Since the air inlet 851 opens downward in the vicinity of the bottom surface of the housing 2 , it is possible to effectively prevent 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 through 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 inside the left duct portion 71 . The cooling air that has flowed through the left duct portion 71 flows inward from the intake port 421 of the left tubular portion 42 of the sensor case 40 .

When the cooling fan 75 in the right duct portion 72 is driven, outside air is sucked into the intake passage portion 95 from the air inlet 951 at the front lower portion of the right front panel 90 . Since the air inlet 951 is also open downward near the bottom surface of the housing 2 , it is possible to effectively prevent high-temperature air around the grill chamber 10 from being sucked into the intake passage 95 . Further, as described above, since the main body portion 731 of the right duct portion 72 and the rear opening portion of the rear tubular portion 92 of the right front panel 90 are in close contact with each other, the insertion tubular portion 735 of the right duct portion 72 is doubly sealed. This effectively prevents the high-temperature air inside the housing 2 from flowing forward through the rear tubular portion 92 of the right front panel 90 and being sucked into the air inlet 951 . This configuration is the same on the left front panel 80 side.

The air sucked into the intake passage portion 95 flows rearward through 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 through the right duct portion 72 . The cooling air that has flowed through the right duct portion 72 flows inward from the intake port 431 of the right cylindrical portion 43 of the sensor case 40 .

Here, as shown in FIG. 10, in the right front panel 90, when the operation portion 9 is pulled forward and used, the upper end side of the decorative plate 6D fixed to the front surface of the operation portion 9 falls forward. It is in 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 operating portion 9 is housed in the frame portion 91B of the right front panel 90, the decorative plate 6D is vertically upright. The front side of the air inlet 951 is closed. However, since a pair of inclined portions 96 are arranged on both left and right sides of the air inlet 951, air is sufficiently taken in from the lateral direction through a gap formed between the decorative plate 6D and the pair of inclined portions 96. be able to. Moreover, regardless of the posture of the operation unit 9, the air inlet 951 is open downward and is not blocked by the decorative plate 6D. Therefore, the stove 1 can sufficiently take air into the intake passage portion 95 from the air inlet 951 .

The flow of cooling air in the sensor case 40 will be described with reference to FIGS. 7 and 8. FIG. The cooling air that has flowed into the left tubular portion 42 is split by the left inlet 52 provided in the forward protruding portion 611 into the lower surface side and the upper surface side of the main body portion 41 at a predetermined ratio. On the other hand, the cooling air that has flowed into the right cylindrical portion 43 is also split by the right inlet 53 provided in the forward protruding portion 621 into the lower surface side and the upper surface side of the main body portion 41 at a predetermined ratio. In the present embodiment, the heat resistance of the sensors 31-39 is lower than that of the electrical substrate 100 and the sensors 31-39. Furthermore, since the sensors 31 to 39 are located on the far side of the electrical board 100 , they are easily affected by the heat from the top flame burner 25 in the grill chamber 10 . For these reasons, in the present embodiment, the opening areas of the left inlet 52 and the right inlet 53 are determined such that the amount of air flowing through the sensor housing portion 60 is greater than the amount of air flowing through the substrate housing portion 50. good.

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 that has flowed from inside the left cylindrical portion 42 to the lower surface side of the main body portion 41 flows into the sensor housing 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 toward the center. As a result, the sensors 31-35 are cooled by the cooling air. The cooling air that has flowed from the left end side to the center side through the left sensor path 60A passes through the first region 683 of the connection tube 68 provided in the center lid portion 653 and is discharged to the outside.

On the other hand, the cooling air that has flowed from inside the right cylindrical 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 36-39 are cooled by the cooling air. The cooling air that has flowed from the right end side to the center side through the right sensor path 60B passes through the second region 684 of the connection tube 68 provided in the center lid portion 653 and is discharged to the outside.

As described above, in the present embodiment, the interior of the connection tube 68 is partitioned by the partition wall 681 and is joined downstream of the partition wall 681, so that the cooling air flowing through the first region 683 is prevented from flowing into the second region 684. can be prevented. Therefore, the cooling efficiency of the sensors 31 to 39 can be maintained well. In addition, since the elastic member 69 attached to the lower end of the connecting tube 68 is in close contact with the periphery of the through hole 271 of the heat shield plate 27, the cooling air leaks to the outside through the gap between the connecting tube 68 and the through hole 271. can prevent

Then, the cooling air that has passed through the first region 683 and the second region 684 of the connecting tube 68 joins on the downstream side of the connecting tube 68, and the gap between the heat shield plate 27 and the upper wall 101 of the grill chamber 10 flows backward (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 chamber 10, so that the temperature rise of the top plate 3 can be suppressed. In addition, since the cooling air flowing through the gap does not easily enter the throats of the stove burner (left burner 4, right burner 5) and grill burner (top flame burner 25, bottom flame burner 26), it is possible to reduce the influence on combustion. . The cooling air that has flowed backward through the gap flows into the duct portion 28 and is discharged to the outside through the grill exhaust port 281 and the exhaust port 7 together with the combustion exhaust from the grill chamber 10 .

The flow of the cooling air diverted to the upper surface side of the main body 41 will be described. As shown in FIG. 7, the cooling air that has flowed from inside the left cylindrical portion 42 to the upper surface side of the rear side portion 45 via the left inlet 52 of the forward projecting portion 611 flows into the substrate accommodating portion 50 from the left end side. . The cooling air flows through the left board path 50A of the board accommodation section 50 from the left end toward the center. As a result, the left half of the electrical board 100 is cooled by the cooling air. The cooling air that has flowed toward the center through the left substrate path 50A is discharged to the outside through the front discharge port 54A. On the other hand, the cooling air that has flowed from inside the right tubular portion 43 to the upper surface side of the rear side portion 45 via the right inlet 53 of the forward projecting portion 621 flows into the substrate accommodating portion 50 from the right end side. The cooling air flows through the right substrate path 50B of the substrate housing portion 50 from the right end toward the center. As a result, the right half of the electrical board 100 is cooled by the cooling air. The cooling air that has flowed toward the center through the right board path 50B is discharged to the outside through the front discharge port 54B.

In this way, in the present embodiment, by partitioning substantially the center of the substrate accommodating portion 50 with the convex portion 51A, the cooling air that has flowed from the left end side to the center side of the left substrate path 50A is discharged from the front side discharge port 54A, The cooling air that has flowed from the right end of the right board path 50B toward the center is discharged from the front discharge port 54B and joined downstream. As a result, for example, the cooling air that has flowed toward the center through the left substrate path 50A can be prevented from flowing into the right substrate path 50B, so that a good cooling efficiency can be maintained. A handle 8A of the grill door 8 is positioned below the front discharge ports 54A and 54B. The cooling air discharged from the front side discharge ports 54A and 54B and combined flows toward the handle 8A. Thereby, since the handle 8A is cooled by the cooling air, it is possible to suppress the temperature rise.

As described above, the stove 1 of the above embodiment includes the housing 2 , the grill chamber 10 , the top plate 3 , the sensor case 40 , the left duct portion 71 and the right duct portion 72 . The sensor case 40 is provided on the lower surface of the top plate 3 so as to straddle the grill chamber 10 in the left-right direction, and supports the sensors 31 to 39 and the electrical board 100 on the lower surface of the top plate 3 .

Cooling air supplied from the intake port 421 flows toward the center through the left sensor path 60A. Cooling air supplied from the intake port 431 flows toward the center through the right sensor path 60B. A connection tube 68 is provided in the central portion of the sensor housing portion 60 . The connection tube 68 discharges the cooling air that has flowed toward the center in the left sensor path 60A and the right sensor path 60B to the outside.

On the other hand, the board accommodating portion 50 arranges the electrical board 100 inside. A left board path 50A and a right board path 50B are formed in the board housing portion 50 . Cooling air supplied from the inlet 421 through the left inlet 52 flows toward the center in the left substrate path 50A. Cooling air supplied from the inlet 431 through the right inlet 53 flows toward the center through the right substrate path 50B. Front side discharge ports 54A and 54B are provided in the central portion of the board accommodating portion 50 . The front discharge ports 54A and 54B discharge to the outside the cooling air that has flowed toward the center in the left board path 50A and the right board path 50B. With these configurations, even if the length of the sensor case 40 in the left-right direction is increased, the sensor housing portion 60 (the left sensor path 60A, the right sensor path 60B) and the substrate housing portion 50 (the left side substrate path 50A, the right side substrate) It is possible to prevent the path 50B) from becoming longer.
