Description

[Detailed Description of the Invention] The present invention relates to a heating coil of an electromagnetic cooker and a cooling mechanism for a control section that controls the output of the heating coil.

In an electromagnetic cooker, the function of a control unit that controls the output of a heating coil, particularly a switching element, deteriorates due to the heat trapped inside the cooker. To prevent this, conventionally, an exhaust port and an intake port are provided at the bottom of the container, and these exhaust ports and intake ports are used to remove the inside of the container, which is heated by the heat radiated from the heating coil and switching element. Hot air was exhausted to the outside of the aircraft, and outside air was sucked into the interior of the aircraft to cool switching elements, heating coils, etc.

However, in the cooling mechanism of such an electromagnetic cooker, the hot air discharged from the exhaust port hits the surface of the cooking table, heating the surface of the cooking table, and a portion of the discharged hot air is sucked in again from the intake port. However, there was a drawback that the cooling effect was significantly reduced.

The present invention has been developed in view of the above-mentioned points, and will be described in detail below based on the drawings.

FIG. 1 is a perspective view of an electromagnetic cooker employing the cooling mechanism of the present invention, in which the upper part 1 of the cooker includes a ceramic top plate 2 on which a cooking pot is placed, and a discharge outlet for discharging hot air from inside the cooker. A hole 3 and a flange 4 are provided. Further, the lower part 5 of the container body is provided with a cover 6 and intake ports 7, 7, . . . . FIG. 2 shows a transparent perspective view of the body of an electromagnetic cooker employing the cooling mechanism of the present invention, and the same parts as in FIG. 1 are given the same numbers. A recess 10 is formed in the recess 8 at the bottom of the receptacle, and a recess 10 is continuously formed inside the recess 8 at the bottom and both sides of the receptacle between the pair of heating coils 9 and 9. A fan 11 is provided as an exhaust port for exhausting air. Further, the recess 8 is covered with a cover 6 shown in FIG.
Up to three ventilation passages 12 are formed. Figure 3 shows
It is a sectional view taken along line A-A in FIG. 2, and includes FIG.
Components that are the same as in FIG. 2 are given the same numbers. Incidentally, here, reference numerals 13 and 14 are control sections each consisting of a heating coil, a switching element, and the like.

Further, B indicates a cooking device housing portion such as a cabinet top plate that stores the electromagnetic cooking device according to the present invention.

FIG. 4 is a sectional view taken along the line CC in FIG. 2, and FIG. 5 is an exploded perspective view of the body of the electromagnetic cooker using the cooling mechanism of the present invention.

In such a cooling mechanism for an electromagnetic cooker, the fan 11 is rotated by an electric motor (not shown) or the like to cool the inside of the cooker, which is heated by the heat generated by the heating coil 13 and the control unit 14 such as a switching element. When the hot air is exhausted from the exhaust port 10, it is discharged from the discharge holes 3, 3 through the ventilation passage 12, as shown by the arrow in FIG. At the same time, outside air is taken in from the intake ports 7, 7, . . . as shown by the arrows in FIG.

As mentioned above, the cooling mechanism of the electromagnetic cooker of the present invention is
An intake port provided on the lower side of the vessel, a recess formed continuously inward of the vessel at the bottom and both sides of the vessel between the pair of heating coils, and the bottom of the vessel. It consists of an exhaust port drilled in a recess in the container, and a discharge hole opened in the upper side of the container.The recess is covered from the outside with a cover, and the cover and the recess allow the air to flow from the exhaust port in the bottom of the container. Forms a ventilation path to the discharge hole on the upper side of the vessel,
By providing a fan at the exhaust port and rotating the fan, outside air is taken in from the intake port on the lower side of the container, and hot air inside the container is transferred to the ventilation path formed by the recess and the cover. Since the hot air is discharged from the discharge hole on the upper side of the cooking device, unlike conventional methods, the hot air does not directly hit the surface of the cooking table and heat the surface of the cooking table. There is no need for air to be sucked in again and the cooling effect to be significantly reduced. Therefore, the control unit comprising switching elements and the like, the heating coil, etc. are sufficiently cooled, and the control unit can accurately control the output of the heating coil. In addition, since the exhaust port is located between the pair of heating coils, it is possible to send air evenly to both heating coils and the control section within the container, making it possible to use a single cooling device. This makes it possible to uniformly cool the paired heating coils, etc.
