no. 1 Embodiment approach
[0027] Below, refer to Figure 1 to Figure 6 A first embodiment in which the present invention is applied to a fixed type induction heating cooker (IH electric stove) will be described.
[0028]First, in figure 1 Among them, an induction heating cooker 1 includes: a rectangular box-shaped casing 2 with an open upper surface, and a top plate assembly 3 installed on the upper surface of the casing 2 . The ceiling unit 3 includes, for example, a glass ceiling 4 and a ceiling frame 5 supporting the ceiling 4 . On top of the top plate 4, a cooking container 105 (refer to Image 6 ).
[0029] On one side in the housing 2, that is, on the right side when viewed from the front, a fan device 6 and an electric circuit unit 7 (refer to Figure 3 ~ Figure 5 ), a baking unit 8 is provided on the other side, that is, on the left side. Between the fan device 6 on the right side and the electric circuit unit 7 and the baking unit 8 on the left side in the housing 2, a dividing plate 10 e...
no. 2 Embodiment approach
[0109] Figure 7 The second embodiment of the present invention is shown, and this second embodiment is different from the above-mentioned first embodiment in the following points. In addition, the same code|symbol is attached|subjected to the same part as 1st Embodiment, and description is abbreviate|omitted, and a different part is demonstrated. The fan unit 6 having the cooling fan 53 is disposed at the front inside the housing 2, and the outlet 56 of the fan cover 55 faces rearward. At the rear of the fan unit 6, an air supply duct 110 is provided. The front part of this blower pipe 110 is communicated with the ejection port 56, and the rear upper part is connected with the accommodation induction heating coils 21, 22 (in Figure 7 Only the induction heating coil 22 on the right side is shown in the figure, and the communication part 26 of the separator 16 is connected.
[0110] In the rear part of the casing 2, an air intake pipe 112 having an air intake passage 111 ha...
no. 3 Embodiment approach
[0116] Figure 8 A third embodiment of the present invention is shown, and this third embodiment is different from the above-mentioned third embodiment in the following points. The air intake passage 121 of the air intake pipe 120 provided at the rear of the housing 2 does not have a labyrinth structure, but in the air intake passage 121, there are provided extensions 122 protruding horizontally from the left and right. The vent 120 a at the lower part of the suction pipe 120 communicates with the rear part of the middle suction pipe 114 .
[0117] In the above configuration, when the cooling fan 53 of the fan unit 6 is rotationally driven, the outside air outside the casing 2 is sucked into the intake duct 120 through the first intake port 49 . The external air sucked into the suction pipe 120 flows downward in the suction pipe 120 as shown by the arrow A7, and then flows forward in the middle suction pipe 114 as shown by the arrow A6 as in the second embodiment, and flows f...
