It is set as a passage form.

Next, the operation of the above configuration will be described.
When one or both of the heating coils 11 and 12 for IH are used, the fan motor 21 is energized, and the fan motor 21 rotates the cooling fan 22 in the counterclockwise direction (arrow B direction) in FIG. Is done. Due to the air blowing action of the cooling fan 22, external air flows from the air inlet 29 through the rear duct 28 and the auxiliary ducts 30, 31, 32 to the electrical component housing part 38 side, and from the front air inlet 23 a to the fan casing. 23 (refer to the front intake path A1), and from the rear duct 28 through the motor housing chamber 37 to the fan casing 23 (refer to the rear intake path A2).

  In this case, the air (wind) passing through the front intake path A1 is mainly transmitted through the auxiliary ducts 30, 31, and 32 to the inverter units 19 and 20 and the control circuit 36 (in addition, the heat radiating members 34a, 34b, and 34c, and the electrical component 35a). , 35b, 35c, etc.), and the electrical component 39 is cooled in the electrical component storage section 38. On the other hand, the air passing through the rear intake path A <b> 2 cools only the fan motor 21 in the motor housing chamber 37. That is, in the present embodiment, the outer peripheral portion 26a of the main plate 26 in the cooling fan 22 described above is formed closer to the fan motor 21 side (rear side intake path A2 side) according to the number of cooling target components (or heat generation amount). Therefore, the front intake path A1 has a larger air volume than the rear intake path A2.

  The air discharged from the blower opening 24 of the fan casing 23 to the closed space S1 side of the upper case 14 is heated from the right IH heating coil 12 side to the left IH heating by the rotation of the cooling fan 22 in the arrow B direction. It flows toward the coil 11 side (see arrow C in FIGS. 1, 3 and 5). At this time, since the air blowing port 24 faces the right IH heating coil 12 and the air guide plate 25 is formed on the outer peripheral edge of the air blowing port 24, the discharged air is directly discharged to the right IH heating coil 12. And a smooth flow in a substantially horizontal direction toward the left IH heating coil 11 is formed.

  Further, a part of this flow flows along the windproof plate 40 at the outer peripheral edge of the radiant heater 13 (see arrow C1 in FIG. 1), and is guided to the heating coils 11 and 12 while avoiding the radiant heater 13. It is like that. Thus, the air that has cooled the heating coils 11 and 12 is discharged to the outside from the discharge port 41 or the rear discharge port 42 on the left side.

According to the above embodiment, the following effects can be obtained.
The cooling fan 22 is composed of a centrifugal fan whose rotating shaft 21a is directed substantially in the front-rear direction, and is disposed below the right IH heating coil 12, and from the heating coil 12 side to the left IH heating coil 11 side. A smooth air flow can be formed by rotating the fan so as to blow air. Thereby, the air blowing action required for cooling the heating coils 11 and 12 can be obtained without increasing the number of rotations of the cooling fan, and noise can be reduced. That is, in the cooling device described in Patent Document 1 described above, since the air is blown toward the top plate by the axial fan, when the wind hits the top plate and changes the flow direction, the flow of the cooling air is disturbed. There was a risk that the resulting pressure loss would increase and cooling would be insufficient. On the other hand, in the present embodiment, the cooling fan 22 made of a centrifugal fan blows air from the right IH heating coil 12 side toward the left IH heating coil 11 side, thereby eliminating the pressure loss problem. In addition, the cooling efficiency can be increased.

In addition, since the air outlet 24 of the fan casing 23 is provided so as to face the heating coil 12 for the right IH, the cooling air can be directly blown from the air outlet 24 to the heating coil 12 so as to be cooled well.
An air guide plate 25 heading toward the left IH heating coil 11 is provided at the air outlet 24 of the fan casing 23. According to this, since the air blown out from the air blowing port 24 smoothly flows to the left side (the other heating coil 11 side) along the top plate 4 (or the heating coil 12), the cooling air as described above. Can be suppressed as much as possible, and the cooling efficiency can be further increased.

  Since the cooling fan 22 is composed of a centrifugal fan that sucks both the front and rear, by sucking from both sides of the cooling fan 22, bidirectional wind from the front and rear toward the cooling fan 22 is generated inside the heating cooker body 3. Can be formed.

  A rear duct 28 and auxiliary ducts 30 and 31 serving as an intake duct that allows the outside of the heating cooker 3 and the fan casing 23 to communicate with each other and forms the front intake path A1 and the rear intake path A2 by suctioning both the front and rear of the cooling fan 22. , 32 are provided. By disposing the fan motor 21, the inverter units 19, 20 and the electrical components 35 a, 35 b, 35 c, 39 separately in both the intake paths A 1, A 2, both the front and rear suction of the cooling fan 22 can be sucked into these parts to be cooled. Good cooling can be performed. Therefore, according to the said Example, the heating coils 11 and 12 and the said cooling object component can be cooled favorably with the one cooling fan 22. FIG.

It was formed closer to the side intake path A2. According to this, in the intake duct, it is possible to secure a larger amount of air in the front intake passage A1 (amount of suction from the front side of the fan casing 23), and to adjust the amount of air according to the number of parts to be cooled, the amount of heat generation, and the like. Can be set.

  Inverter units 19, 20 and electrical components 35a, 35b, 35c, 39, etc. are arranged on the front intake path A1 around the fan casing 23. According to this, since external air flows in the space around the fan casing 23 from the rear to the front, the inverter units 19, 20 and the electrical components 35a, 35b, 35c, 39, etc. can be used effectively. It can be cooled efficiently.

  The inverter unit 20 is disposed below the fan casing 23, and the cooling fan 22 is disposed between the inverter unit 20 and the heating coil 12 for the right IH. According to this, the cooling fan 22 can be brought closer to the heating coil 12 for the right IH and the inverter unit 20 to shorten the air blowing distance, and the pressure loss described above can be suppressed as much as possible, and blown out from the cooling fan 22. Wind can be supplied directly to the heating coil 12 side.

  In the heating cooker body 3, a radial heater 13 as an electric heating means is provided at a position different from the pair of heating coils 11 and 12, and a windbreak plate 40 is provided on the outer peripheral side of the radial heater 13 to avoid blowing air to the radial heater 13. It was. According to this, the ventilation with respect to what does not require cooling, such as the radial heater 13 among heating means, can be avoided. Further, the windbreak plate 40 has an arc shape as a whole, the rear end portion 40a is inclined toward the rear end side of the air blowing port 24 of the fan casing 23, and the air blown from the air blowing port 24 is heated by the heating coil 11. , 12 so as to be guided to the side, it is possible to blow air smoothly and satisfactorily to both the heating coils 11, 12.
