  • hole 19h formed in partition wall 19g of fan case 19 described above serves as a branch point between first air passage 29 and second air passage 31. Thereby, a part of the cooling air flows onto board 15 through hole 19h. On the other hand, the cooling air flowing upward of fan case 19 without passing through hole 19h passes through second air passage 31.
  • the external air indicated by arrow AA which is taken in from air intake port 13a of outer frame 13 (see FIG. 13 ), is taken in from air intake port 17a of fan 17 through air intake port 19f of fan case 19 (see FIGS. 11 and 13 ) disposed so as to face air intake port 13a in the front-rear direction.

  • Air intake port 17a of fan 17 is disposed in a direction in which the intake direction is intersects with air intake port 13a of outer frame 13 in the front-rear direction of door 7 in the upright state. Furthermore, exhaust port 17b of fan 17 is disposed in a direction in which the discharge direction intersects the intake direction of the fan.
  • heating cooker 1 of the present disclosure is arranged such that the intake direction of air intake port 17a of fan 17 and the discharge direction of exhaust port 17b are different. Thereby, the direction of the external air taken in is changed, for example, into an orthogonal direction, so that the external air can be taken in slowly. As a result, it is possible to suppress the intake of steam from another cooker such as a rice cooker and the like or a water heater disposed below heating cooker 1 into heating cooker 1.
  • a part of fan 17 is disposed inside radio wave leakage prevention plate 25. Thereby, the height dimension of door 7 can be shortened. As a result, heating cooker 1 can be reduced in size.

That is, hole 19a configuring the through-hole is formed in fan case 19. Thereby, second air passage 31 configuring an air passage from fan 17 to the rear surface of fan case 19 through hole 19a is formed. As a result, the rear surface of fan case 19 can be effectively cooled.
  • fan case 19 of heating cooker 1 of the present disclosure includes upper hole 19b formed upward of board 15, and third air passage 33 extending from board 15 to the rear surface of fan case 19 through upper hole 19b. That is, third air passage 33 configuring an air passage in which the cooling air that has cooled board 15 passes through upper hole 19b of fan case 19 and reaches the rear surface of fan case 19 is formed. Thereby, the rear surface of fan case 19 can be effectively cooled.
  • door 7 of heating cooker 1 of the present disclosure includes first metal plate 21 configuring metal plates that cover at least a part of the rear side of fan case 19, and fourth air passage 35 between the rear surface of fan case 19 and the front surface of first metal plate 21. That is, the cooling air that has passed through third air passage 33 reaching the rear surface of fan case 19 passes through fourth air passage 35 configuring an air passage between the rear surface of fan case 19 and first metal plate 21. Thereby, first metal plate 21 is cooled. As a result, the heat shielding effect of first metal plate 21 on board 15 is furthermore improved. In addition, an air curtain is formed between fan case 19 and first metal plate 21 by fourth air passage 35. Thereby, the heat transferred to first metal plate 21 can be absorbed by the cooling air. As a result, the function of first metal plate 21 as a heat shield plate is further improved, and the heat transfer to fan case 19 can be efficiently reduced.
  • a heating element that generates heat during operation is mounted on board 15 of heating cooker 1 of the present disclosure, and the heating element is disposed on first air passage 29. Thereby, the heating element can be efficiently cooled by the cooling air flowing on first air passage 29.
