チング素子の電気部品や、加熱コイルへ送風を行
いこれ等の冷却を図つていた。 In the circuit components of such an electromagnetic cooker, the temperature of the switching element rises significantly due to self-heating, and the heating coil causes a large temperature rise due to self-heating and heat conducted from the pot, and requires cooling. For this reason, the electromagnetic cooker is provided with a fan, which blows air to the electrical components of the switching element and the heating coil to cool them.
ところが、通常、加熱コイルを天板間は挟く、

によつて生じる旋回流のため多口電磁調理器では
各加熱コイルに供給される風の風量が不均一にな
り、各加熱コイルに冷却差を生じる。 However, usually the heating coil is sandwiched between the top plates.
During this time, it was difficult to blow air, so the heating coil was not sufficiently cooled. In addition, in a multi-burner electromagnetic cooker, the amount of air supplied to each heating coil becomes non-uniform due to the swirling flow generated by the rotation of the fan, resulting in a cooling difference between the heating coils.

In these figures, 1 and 1 represent chassis plates made of non-magnetic metal such as aluminum and bent into an L-shape, and two chassis plates 1 and 1 are arranged to form a U-shape. It is located. Reference numerals 2, 2, . . . are electrical components attached to the inner surfaces of the chassis plates 1, 1 arranged in a U-shape, which generate a high frequency current and constitute an inverter circuit. Reference numerals 3 and 3 indicate heat dissipation fins provided on the inner surface of the chassis plates 1 and 1 as described above, and switching elements 4 and 4 that generate a particularly large amount of heat among electrical components and are sensitive to heat, e.g.
GTO, transistor, SCR, etc. are installed. Reference numerals 5 and 5 represent control boards provided on the outer surfaces of the chassis plates 5, 5, and a control circuit for controlling the inverter constituted by the electrical components 2, 2, . . . is formed on these control boards 5, 5. 6, 6 are heating coils arranged and fixed on the upper parts of the chassis plates 1, 1 and the heat radiation fins 3, 3, respectively, via heating coil stands 7, 7, and in the center part there is a thermostat 8 for detecting the temperature of the pot. , 8 are provided. It should be noted that the distance between the heating coils 6, 6 and the top plate (dotted line in Figure 3) is only small in order to heat the pot.
Reference numeral 9 denotes a fan installed on one opening surface of the chassis plates 1, 1 arranged in a U-shape, and as the fan 9 rotates (in the direction of the arrow in FIG. 3), the chassis plates 1, 1 and the heating coil are heated. Wind is sent to the space surrounded by 6 and 6. 10 is a fan cover provided to cover the side surface of the opening other than the part where the fan 9 is provided, and 11 is a fan guide that protrudes outward like an eave above the fan 9 and is made of a non-magnetic material such as aluminum. These fan cover 10 and fan guide 11 serve as an air path guide plate. Further, the fan cover 10 and the fan guide 11 are fixed to the bent sides 12 of the chassis plates 1, 1 with screws 13 or the like, thereby fixing the chassis plates 1, 1 together. 14 is a heat dissipation fin 3,3
A wind panel is screwed together with the heating coils 6, 6 on the upstream side of the upper end, and includes the heating coils 6, 6.
6. Adjust the amount of air sent to the upper surface part, and fix the upper ends of both heat dissipation fins 3, 3 together. Fourth
The figure is a perspective view of the wind panel 14, where 15 is a screw hole for fixing, and 16 is an air volume adjustment surface, which guides the air sent from the fan 9 to the upper surface of the heating coils 6, 6. . Note that the air volume adjusting surfaces 16 have different heights on the left and right sides to adjust the volume of air supplied to the heating coils 6, 6.

The switching elements 4, 4, etc. are cooled. Further, the wind from the fan 9 hits the air volume adjustment surface 16 of the wind panel 14 and is sent to the upper surface of the heating coils 6, 6. At this time, as mentioned above, the fan 9 rotates to the left (third
(Fig.), the wind becomes a swirling flow, and the third
In the figure, a strong wind is blown toward the heating coils 6, 6 on the left. However, since the air volume adjustment surface 16 of the wind panel 14 is formed high on the left side and low on the right side, part of the air supplied to the left side is blocked by the air volume adjustment surface and flows to the heating coil 6 on the right side. A uniform amount of air is sent to both the left and right heating coils 6, 6. Therefore, the heating coils 6,6 and the thermostats 8,8 are equally cooled, due to the difference in the cooling state of the thermostats 8,8. No sensing temperature of the cooking pot occurs.

Since the cutting plate is provided, this air volume adjustment plate allows a large amount of air from the fan to be sent to the upper surface of the heating coil, thereby improving the cooling effect of the heating coil. In addition, this air volume adjustment plate allows the air from the fan to be sent evenly to both heating coils and the thermostat, so that the two thermostats are cooled evenly, and there is no difference in the detected temperature of the cooking pot on the top plate. The temperature of the cooking pot can be adjusted reliably.
