Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to an improvement of an induction heating device that performs induction heating using a heating coil through which a high-frequency current flows.

[Technical background of the invention]

Generally, an induction heating device, such as an electromagnetic cooker, has a top plate disposed on the top surface of the main body, and a heating coil disposed on the bottom surface of the top plate. It is configured to induction heat the iron pot etc. placed on top. by the way,
Conventionally, the output range of the heating coil is divided into five stages, for example, and five indicator lamps that also serve as cooking lamps are provided corresponding to each output range, and when adjusting the output of the heating coil, the output range is set. In many cases, a corresponding indicator lamp was lit to display the set output range.

[Problems with background technology]

Although the output of the heating coil is continuously changed and adjusted, each indicator lamp displays the output in stages, so you can accurately know the output status of the heating coil. It was inconvenient not being able to do that. Furthermore, since a relatively large number of indicator lamps are used, the structure becomes complicated and costs increase.

[Purpose of invention]

The purpose of this invention is to provide an induction heating device that can accurately display the output state of the heating coil, is easy to use, and has an improved appearance, simplified configuration, and reduced cost.

[Summary of the idea]

An output adjustment mechanism equipped with an operation section that continuously adjusts the output of the heating coil, and an output display section in which a pointer that operates in conjunction with the operation of this operation section is mounted in the display window are provided, and the output display section The pointer is made of a translucent material, and a cooking lamp is provided at the base end of the pointer that lights up when a high-frequency current flows through the heating coil and introduces this light into the inside of the pointer. It is something.

[Example of idea]

FIGS. 1 and 2 show an embodiment of this invention. FIG. 1 shows the external appearance of an induction heating device, such as an electromagnetic cooker, where 1 is a main body and 2 is a top plate disposed on the top surface of the main body 1. FIG.
A heating coil 3 is disposed on the bottom surface of the top plate 2. In addition, an output display section 4 and a power lamp 5 are provided on the top surface of the main body 1 adjacent to the top plate 2, and a knob 6 for operating a power switch and a knob 6 for adjusting the output are provided on one side of the main body 1. A slide knob 7 is provided respectively. The output display section 4 is provided with a pointer 9 for output display within a display window 8 formed in the main body 1 so as to be movable back and forth. As shown in Fig. 2, this pointer 9 is made of a translucent material such as transparent or semi-transparent synthetic resin and is formed into a substantially L shape, and the base end of this pointer 9 constitutes an output adjustment mechanism. It is attached to an operation knob (operation section) 11 of a volume 10. Further, a cooking lamp 12 is embedded in the base end of the pointer 9. This cooking lamp 12 lights up when a high frequency current flows through the heating coil 3. The volume 10 is arranged below the display window 8 to variably control the output of the high frequency inverter and continuously adjust the output of the heating coil 3 by sliding an operation knob 11. . Further, the slide knob 7 is fixed to the tip of the operating knob 11. In addition,
A small object load detecting device (not shown) is provided in the main body 1, and if this small object load detecting device detects that the pot etc. placed on the top plate 2 is inappropriate, the heating coil 3 No high-frequency current is applied to the unit, and the cooking lamps are not turned on.

Therefore, in the case of the above configuration, when the power switch is turned ON using the knob 6, the power lamp 5
lights up. When a high frequency current flows through the heating coil 3, the cooking lamp 12 lights up. The light from the cooking lamp 12 is repeatedly reflected inside the pointer 9 as shown by the dashed-dotted line arrow in FIG. 2, and is guided to the tip side, thereby making the tip of the pointer 9 clearly visible. Therefore, the heating coil 3 displayed on the output display section 9
The output status can be easily checked. In addition, the pointer 9 continuously moves back and forth within the display window 8 in conjunction with the sliding operation of the slide knob 7, so that the output status of the heating coil 3 can be continuously displayed. The output state of the coil 3 can be displayed accurately, making it easier to use than before. Furthermore, since the light from the cooking lamp 12 is introduced into the translucent pointer 9 to make it clear, the pointer 9 can be illuminated by light from a power lamp disposed around the pointer 9, for example.
It is possible to prevent the appearance of the pointer 9 from becoming difficult to see due to the shadow of the pointer 9 itself or from changing the appearance of the pointer 9 as the pointer 9 moves, as in the case where the pointer 9 is illuminated to make it clear. You can also try to improve it. Further, since the output of the entire heating coil 3 can be clearly displayed using one cooking lamp 12, the structure can be simplified and the cost can be reduced compared to the conventional method.

Note that this invention is not limited to the above embodiments. For example, as shown in FIG.
An extension part 22 extending in the sliding direction of the operating knob 11 is provided at the base end of the operating knob 11 , and a serrated reflective part 23 is formed on the upper part of the extension part 22 . It is also possible to adopt a structure in which the light from the cooking lamp 24 is repeatedly reflected within the extension part 22 and guided to the tip side of the pointer 21 by disposing the light from the cooking lamp 24 below the extension part 22 so as to face each other. Furthermore, it goes without saying that various other modifications can be made without departing from the gist of the invention.

[Effect of idea]

According to this invention, an output adjustment mechanism equipped with an operation part that continuously adjusts the output of the heating coil and a pointer that operates in conjunction with the operation of this operation part each control the output display part installed in the display window. The pointer of the output display section is formed of a translucent material, and the pointer is equipped with a cooking lamp that lights up when a high frequency current flows through the heating coil and causes the light to be introduced into the pointer. Since it is installed on the base end side, the output status of the heating coil can be displayed continuously and accurately, making it easier to use.
Furthermore, the appearance can be improved, the configuration can be simplified, and costs can be reduced.
