３等の部品を配置させていた。Conventional technology Induction heating cookers use an inverter device to convert the commercial frequency to 2.
Although it is converted to a high frequency of 0 to 30 KH2O, the inverter parts, which consist of transistors, capacitors, heating coils, etc., self-heat during solenoid operation. Furthermore, the temperature inside the refrigerator increases due to radiant heat from the pot placed on the pot holding plate. For this reason, induction heating cookers are equipped with cooling fans for cooling the components. As shown in Figure 1, the conventional induction heating cooker is
A propeller fan 11 is used as a cooling fan, and this propeller fan 11 is located at a part of the corner of the main body, and around it is a heating coil /l/12. ) Parts such as Ranjistara 3 were arranged.

していた。Problems to be Solved by the Invention However, in the conventional cooling structure described above, the cooling fan supplies an almost equal amount of air to each component, so the amount of air is sufficient to suppress the temperature rise of the component whose temperature rises most rapidly. The rotation speed of the cooling fan was determined according to the Therefore,
The problem was that the rotational speed was too high and the noise was high.

回転数を下げて騒音を低く抑えることができる。In other words, by calculating the required air volume for each component to be cooled, and by providing a guide so that the required air volume is supplied to each component, each component is provided with a cooling air volume that can suppress the temperature rise of each component. Air is blown. Therefore, since a small amount of air is required for parts with a small temperature rise, the total amount of air can be made smaller than in the past, and the number of revolutions of the cooling fan can be lowered to keep noise low.
