The fan 17 functions to suck outside air (outside air) into the door 7 and send it out of the door 7. As a result, the substrate 15 raised in temperature by the heat from the heating chamber 5 is cooled. The fan 17 is disposed in front of the radio wave leakage prevention plate 25 (−Y direction).

The fan case 19 covers the back of the substrate 15 and the fan 17 and forms an air passage through which the cooling air generated by the fan 17 flows.

The first metal plate 21 is disposed behind the substrate 15 with the fan case 19 interposed therebetween. The first metal plate 21 functions to shield heat transmitted from the heating chamber 5 to the substrate 15.

The second metal plate 23 is disposed so as to cover the rear surface of the first metal plate 21. Similarly to the first metal plate 21, the second metal plate 23 also functions to shield heat transmitted from the heating chamber 5 to the substrate 15.

The radio wave leakage prevention plate 25 is made of a metal plate such as a hot dip galvanized steel plate or an aluminum plated steel plate, and is attached to the rear side of the outer frame 13. The radio wave leakage prevention plate 25 prevents radio waves (microwaves) from leaking outside from the heating chamber 5 through the door 7.

The inner frame 27 is attached to the rear side of the radio wave leakage prevention plate 25. At this time, the inner frame 27 is disposed so as to sandwich the radio wave leakage prevention plate 25 between the inner frame 27 and the outer frame 13.

Next, the configuration of the door 7 will be further described with reference to FIGS.

FIG. 4 is a rear perspective view of the door 7 with the inner frame 27 removed. 5 is a rear perspective view of the door 7 shown in FIG. 4 with the radio wave leakage prevention plate 25 removed. 6 is a rear perspective view of the door 7 shown in FIG. 5 with the second metal plate 23 removed.

The 2nd metal plate 23 is arrange | positioned at the other side (right side) of the longitudinal direction (X direction) of the outer frame 13, as shown in FIG. The second metal plate 23 is located behind the substrate 15 and is disposed between the heating chamber 5 and the first metal plate 21 in the front-rear direction (Y direction).

As shown in FIG. 6, the first metal plate 21 is located behind the substrate 15 and is disposed between the second metal plate 23 and the fan case 19 in the front-rear direction (Y direction).

Next, the configuration of the door 7 will be described with reference to FIGS. 7 and 8.

FIG. 7 is a rear perspective view of the state where the first metal plate 21 is removed from the door 7 shown in FIG. FIG. 8 is a rear view of the state in which the first metal plate 21 is removed from the door 7 shown in FIG. 6.

As shown in FIG. 7, the fan case 19 is located behind the substrate 15 and is disposed between the substrate 15 and the second metal plate 23 in the front-rear direction (Y direction).

The fan case 19 is provided with a hole 19a, which is a through hole, near the inside (left side) on the upper side. The hole 19a is formed as a long hole extending in the vertical direction (Z direction), for example. Two holes 19a are formed in the fan case 19 side by side in the vertical direction. At the rear of the hole 19 a, for example, an L-shaped cover 19 c that opens to the front side and the outside (right side) in the longitudinal direction of the door 7 is attached to the fan case 19. The cover 19c functions to change the direction so that the cooling air flowing backward from the substrate 15 flows outward on the rear surface of the fan case 19.

The fan case 19 has a plurality of upper holes 19b formed along the longitudinal direction of the door 7 in the vicinity of the upper portion. Thereby, the cooling air flowing from the lower end to the upper end of the substrate 15 flows into the rear surface of the fan case 19 through the upper hole 19b.

Further, on the other side (right side) in the longitudinal direction (X direction) of the door 7, a wall 19 d protruding rearward (Y direction) is disposed in the vicinity of the outer side (right side) on the lower side of the fan case 19. Thereby, the cooling air flowing toward the outer side from the cover 19c can be reflected by the wall 19d and changed in the direction toward the inner side.

Next, the configuration of the door 7 will be further described with reference to FIGS. 9 and 10.

FIG. 9 is a rear perspective view of the fan case 19 removed from the door 7 shown in FIG. FIG. 10 is a rear view of the state in which the fan case 19 is removed from the door 7 shown in FIG.

As shown in FIGS. 9 and 10, the outer frame 13 of the door 7 has an intake port 13a for taking in outside air, which is formed at the lower part on the other side (right side) in the longitudinal direction (X direction). Further, a substrate 15 is attached to the outer frame 13 together with the display unit 9. A fan 17 is disposed above the intake port 13a in the vicinity of the lower portion of the outer frame 13 on the other side in the longitudinal direction.

As shown in FIG. 11, the fan 17 has an intake port 17a and an exhaust port 17b. The opening of the air inlet 17a is provided toward the front-rear direction (Y direction) of the door 7. On the other hand, the opening of the exhaust port 17b of the fan 17 is provided in the upward direction (Z direction) of the door 7.

Thereby, the intake port 17a of the fan 17 that sucks in outside air is arranged so that the suction direction is the front-rear direction (Y direction) of the door 7 in the upright state, that is, the direction intersecting the intake port 13a of the outer frame 13. (See FIG. 13). The suction direction of the fan 17 and the direction in which the intake port 13a intersects may be a right angle. On the other hand, the exhaust port 17b of the fan 17 is arranged so that the discharge direction intersects the suction direction of the intake port 17a. Note that the direction in which the discharge direction of the intake port 17a of the fan 17 intersects the suction direction of the exhaust port 17b of the fan 17 may be a right angle. Therefore, the rotation axis of the blades of the fan 17 is arranged along the front-rear direction (Y direction). The fan 17 is exemplified by a sirocco fan, for example.

The outer frame 13 includes a first partition wall 13c and a second partition wall 13d that extend rearward (Y direction) from the rear surface of the outer frame 13. A groove 13b is formed by the first partition 13c, the second partition 13d, and the rear wall 13e that is a part of the rear surface of the outer frame 13. The groove 13 b extends upward from the exhaust port 17 b of the fan 17.

Next, the positional relationship between the radio wave leakage prevention plate 25 and the fan 17 will be described with reference to FIG.

FIG. 12 is a diagram for explaining the positional relationship between the radio wave leakage prevention plate 25 of the door 7 of the heating cooker 1 and the fan 17.

As shown in FIG. 12, at least a part of the fan 17 is disposed inside the radio wave leakage prevention plate 25 and is covered with the radio wave leakage prevention plate 25 in the rear view. Specifically, the fan 17 is disposed so that, for example, the upper part including the exhaust port 17 b and the vicinity of the center part are embedded inside the radio wave leakage prevention plate 25. And the lower part of the fan 17 is arrange | positioned so that it may protrude below from the lower edge part 25a of the electromagnetic wave leakage prevention plate 25. FIG. With this arrangement, it is not necessary to arrange the intake port and the exhaust port in the vertical direction as in the conventional fan configuration, so that the length (dimension) of the door 7 in the height direction can be shortened.

Next, the air path of the cooling air flowing from the fan 17 will be described with reference to FIGS.

FIG. 13 is a view of the door 7 as seen from the vertical cross section around the fan 17. FIG. 14 is a front perspective view of the fan 17, the fan case 19, and the substrate 15. FIG. 15 is a diagram illustrating the air path. In FIG. 15, the fan case 19 is indicated by a broken line, and the inside thereof is seen through.

As shown in FIG. 14, the fan case 19 further includes an outer wall 19e, a partition wall 19g, a hole 19h, and a front wall 19k. The outer side wall 19e extends from the inner (left side) end of the front surface of the fan case 19 to the front (−Y direction). The partition wall 19g extends forward (−Y direction) in parallel to the outer wall 19e on the outer side (right side) of the outer wall 19e. The hole 19h is opened in the partition wall 19g at a position corresponding to a branch point between the first air passage 29 and the second air passage 31 that constitutes an air passage described later. The front wall 19k is constituted by a part of the front surface of the fan case 19. A groove 19m is formed by the outer wall 19e, the partition wall 19g, and the front wall 19k. Specifically, the groove 19 m extends upward from the exhaust port 17 b of the fan 17.

Then, the groove 13b of the outer frame 13 and the groove 19m of the fan case 19 are fitted in the front-rear direction (Y direction). As a result, an air passage is formed in which the outside air exhausted from the exhaust port 17b of the fan 17 flows upward (in the Z direction) through the fan case 19. At this time, the hole 19 h formed in the partition wall 19 g of the fan case 19 described above serves as a branch point between the first air passage 29 and the second air passage 31. Thereby, a part of cooling air flows on the board | substrate 15 through the hole 19h. On the other hand, the cooling air that flows upward of the fan case 19 without passing through the hole 19 h passes through the second air passage 31.

Hereinafter, the air path formed in the door 7 will be described in detail.

First, the outside air indicated by the arrow AA taken in from the intake port 13a (see FIG. 13) of the outer frame 13 is the intake port 19f (see FIG. 11 and FIG. 11) of the fan case 19 arranged to face the intake port 13a in the front-rear direction. 13), the air is sucked from the air inlet 17a of the fan 17. At this time, the outside air taken in from below the fan 17 circulates behind the fan 17 as shown by an arrow BB, is sucked from the intake port 17a, and is discharged from the exhaust port 17b as shown by an arrow CC. .

The cooling air discharged from the exhaust port 17b at the top of the fan 17 flows upward along the groove 13b constituting the air path. At this time, as shown in FIG. 14, in the middle of the air path flowing upward along the groove 13b of the outer frame 13, the cooling air is branched to the substrate 15 side by a hole 19h formed in the partition wall 19g. One air passage 29 is formed. Therefore, the cooling air that has flowed on the substrate 15 along the first air passage 29 flows toward the upper hole 19b of the fan case 19 as indicated by an arrow DD in FIG. The cooling air passing through the upper hole 19b flows on the rear surface side of the fan case 19 along the third air passage 33 shown in FIGS. And the 3rd air path 33 is connected with the 4th air path 35 which flows between the fan case 19 and the 1st metal plate 21, as shown in FIG.

On the other hand, the cooling air that branches off from the first air passage 29 and flows further upward along the groove 13 b of the outer frame 13 passes through the hole 19 a (see FIGS. 7 and 15) of the fan case 19. Along the rear side of the fan case 19. And it connects with the 4th air path 35 (refer FIG. 8) which flows between the fan case 19 and the 1st metal plate 21. FIG.

As described above, an air path composed of, for example, the first air path 29 to the fourth air path 35 is formed inside the door 7. Then, the outside air sucked through the fan 17 flows in the fan case 19 along the air path to cool the substrate 15 and the like.

As described above, the heating cooker 1 of the present disclosure includes the heating chamber 5 having the opening 3b and the door 7 that covers the opening 3b of the heating chamber 5 so as to be openable and closable. The door 7 is provided on the outer frame 13, a radio wave leakage prevention plate 25 attached to the rear side of the outer frame 13, an inner frame 27 that sandwiches the radio wave leakage prevention plate 25 with the outer frame 13, and a lower portion of the outer frame 13. The air intake port 13a for taking in outside air is provided. Further, the door 7 includes a substrate 15 attached to the outer frame 13, a fan 17 attached to the outer frame 13, and a first air passage 29 extending from the fan 17 to the substrate 15. The fan 17 is disposed in front of the radio wave leakage prevention plate 25. At least a part of the fan 17 is disposed inside the radio wave leakage prevention plate 25 in the rear view. The intake port 17a of the fan 17 is arranged in a direction in which the suction direction intersects the intake port 13a of the outer frame 13 in the front-rear direction of the door 7 in the upright state. Further, the exhaust port 17b of the fan 17 is disposed in a direction in which the discharge direction intersects the suction direction of the fan.

The following effects can be obtained from the configuration of the heating cooker 1.

First, the heating cooker 1 according to the present disclosure is arranged such that the suction direction of the intake port 17a of the fan 17 and the discharge direction of the exhaust port 17b are different. Thereby, since the direction of the external air taken in is changed to the direction orthogonal, for example, the intake of external air can be loosened. As a result, for example, it is possible to suppress the intake of steam from other cookers or water heaters such as a rice cooker disposed below the cooker 1 into the cooker 1. A part of the fan 17 is arranged inside the radio wave leakage prevention plate 25. Thereby, the height dimension of the door 7 can be shortened. As a result, the cooking device 1 can be downsized.

Moreover, the heating cooker 1 of this indication is provided with the fan case 19 which covers the fan 17 and the board | substrate 15, and the outer frame 13 is formed in the inside by the 1st partition 13c and the 2nd partition 13d which comprise a partition. A groove 13b is provided. The first air passage 29 is formed by the groove 13 b of the outer frame 13 and the fan case 19. That is, the fan case 19 and the groove 13 b of the outer frame 13 form a first air passage 29 that forms an air passage from the fan 17 to the substrate 15. Therefore, the outside air sucked from the inlet 13 a of the outer frame 13 is appropriately blown to the substrate 15. Thereby, the board | substrate 15 can be cooled effectively with external air.

The fan case 19 of the cooking device 1 according to the present disclosure has a hole 19a that is formed behind the groove 13b of the outer frame 13 and forms a through hole. The fan case 19 passes through the hole 19a from the fan 17 and passes through the hole 19a. A second air passage 31 that reaches the rear surface of 19 is formed by the groove 13 b of the outer frame 13 and the fan case 19. That is, the fan case 19 is formed with a hole 19a that constitutes a through hole. Thereby, the 2nd air path 31 which comprises the air path from the fan 17 through the hole 19a to the rear surface of the fan case 19 is formed. As a result, the rear surface of the fan case 19 can be effectively cooled.

In addition, the fan case 19 of the cooking device 1 of the present disclosure includes an upper hole 19b formed above the substrate 15, and a third air passage 33 extending from the substrate 15 through the upper hole 19b to the rear surface of the fan case 19. . That is, a third air passage 33 is formed, which forms an air passage through which the cooling air that has cooled the substrate 15 passes through the upper hole 19 b of the fan case 19 and reaches the rear surface of the fan case 19. Thereby, the rear surface of the fan case 19 can be effectively cooled.

Further, the door 7 of the heating cooker 1 of the present disclosure includes a first metal plate 21 constituting a metal plate that covers at least a part of the rear side of the fan case 19, a rear surface of the fan case 19, and the first metal plate 21. A fourth air passage 35 between the front surface is provided. That is, the cooling air that has passed through the third air passage 33 reaching the rear surface of the fan case 19 passes through the fourth air passage 35 that forms an air passage between the rear surface of the fan case 19 and the first metal plate 21. Thereby, the 1st metal plate 21 is cooled. As a result, the heat shielding effect of the first metal plate 21 on the substrate 15 is further improved. In addition, an air curtain is formed between the fan case 19 and the first metal plate 21 by the fourth air passage 35. Thereby, the heat transferred to the first metal plate 21 can be absorbed by the cooling air. As a result, the function of the first metal plate 21 as a heat shield plate is further improved, and heat transfer to the fan case 19 can be efficiently reduced.

Further, a heating element that generates heat during operation is mounted on the substrate 15 of the cooking device 1 of the present disclosure, and the heating element is disposed on the first air path 29. Thereby, the heating element can be efficiently cooled by the cooling air flowing on the first air passage 29.

It should be noted that, by appropriately combining any of the above-described various embodiments and modifications, it is possible to achieve the respective effects.
