Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an electromagnetic cooker equipped with a display device that indicates cooking settings.

[Conventional technology]

FIG. 3 shows a circuit diagram of a conventional electromagnetic cooker disclosed, for example, in Japanese Utility Model Application Publication No. 55-47193. In the figure, 1 is a power plug, 2 is a power conversion circuit (inverter circuit), and 3 is a A heating coil, 4 is a heating container such as a pot placed above the heating coil 3 to be heated, 5 is a set volume for output or cooking temperature, 6 is a control circuit, 7 is a lighting control circuit, and 8 is a light emitting device. This is a display device for displaying the set amount of output or cooking temperature by arranging a predetermined number (plurality) of display elements such as diodes (LEDs).

In the conventional electromagnetic cooker configured as described above, the high frequency current converted from the power conversion circuit 2 flows through the heating coil 3, so that the Pot 4
Heating is achieved by inducing eddy currents in the bottom of the pot through electromagnetic inductive coupling.

The amount of heating or the temperature to be controlled is set by the setting volume 5,
It is controlled by operating the control circuit 6.
The power value or temperature value set by the setting volume 5 is notified to the user by lighting a plurality of display elements of the display device 8 through the lighting control circuit 7 according to the set amount of power or temperature. It had been.

[Problem that the invention seeks to solve]

However, with the display using a plurality of display elements as described above, it is not possible to display the setting amount more or less in an analog manner, in other words, it can only be displayed in stages.
Furthermore, if the cooking mode is different at the same setting position, even though the meaning of the setting amount is different, this cannot be read from the display element, so it is difficult to know what the current setting amount means. I needed to tighten it up.

The present invention has been made in order to solve this problem, and aims to provide an electromagnetic cooker that allows you to simultaneously know the cooking mode and the set amount by simply looking at the guide that indicates the set amount, such as temperature.

[Means for solving problems]

The electromagnetic cooker of the present invention uses light from a single light source that passes through any one light-changing member that is linked to a cooking mode switching device and changes the color of the light to a pointer that indicates a desired power value or temperature value. A light display section made of a prism that emits light in a predetermined direction is provided, and the selected cooking mode is displayed with light in a mode corresponding to the mode.

[Effect]

According to the electromagnetic cooker of the present invention, the pointer indicating the power value or the temperature value converts light from a single light source into light in a state corresponding to the cooking mode by the light variable member interlocking with the cooking mode switching device. It can be displayed by changing color, and when a certain cooking mode is selected, the selected cooking mode is displayed by a light of a mode corresponding to that cooking mode, and furthermore, it is displayed by this light. The light indicator moves with the pointer.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In FIG. 1, 9 is a cooking mode switching device;
This is for selecting one of the cooking modes: tempura temperature control, warming, simmering temperature control, or normal heating control. Reference numeral 9a denotes an operating lever of the cooking mode switching device 9. A variable plate 10 is connected to the operating lever 9a, and a variable plate made of glass or cellophane or the like is used to change the color of the emitted light when light passes through it. Optical members 10a to 10c are arranged in series. A single lamp 11 is disposed in front of these light-changing members 10a to 10c, and the operating lever 9a
As a result of the movement of the light changing members 10a to 10c, one of the light changing members 10a, 10b, or 10c is made to face each other. Reference numeral 12 denotes a guide tube bent into a substantially L-shape, and an opening surface 12a at one bent end faces the lamp 11, and between the opening surface 12a and the lamp 11, the operation lever 9a and By moving the connected light variable plates 14, any one of the light variable members 10a to 10c is positioned. A slit 13 extending in the longitudinal direction is formed at the other end of the guide tube 12, and a prism 14a attached to the tip of a pointer 14 that moves in conjunction with the setting volume 5 passes through the slit 13. It is located within the guide tube 12. Reference numeral 15 designates a design panel placed above the pointer 14, and this design panel 14 has a display for visually recognizing the pointer formed in the longitudinal direction opposite the slit 13, where the pointer 14 located on the back side from above can be confirmed. window 15a
is provided.

According to the embodiment of the present invention configured as described above, when the electromagnetic cooker is operated, the lamp 11 emits light. Then, by the cooking mode switching device 9,
Each mode of tempura, warming, or normal heating is selected, and any one of the light-changing members 10a to 10c, for example, the light-changing member 10b of the light-changing plate 10, which changes the light in accordance with each mode by selecting the mode, is connected to the guide tube. 1
It is located in front of the opening surface 12a of No. 2. The color of the light emitted from the lamp 11 is changed to a color-changed light by passing through the light-changing member 10b, and the light is transmitted through the guide tube 12 to the pointer 14 protruding into the slit 13 of the guide tube 12, as shown in FIG. The light enters a prism 14a attached to the tip, is bent, and is emitted in a predetermined direction. Therefore, the display window 1 of the design panel 15
5a, the luminescent color of the predetermined cooking mode can be seen, and the setting amount can be confirmed by the pointer 14 that moves in conjunction with the setting volume 5, so the position of the pointer 14 can be seen through the design panel 15. At the same time, you can determine the current setting amount and cooking mode of the induction cooktop.

Note that the configuration and functions other than those described above are the same as those of the conventional example shown in FIG. 3, and will therefore be omitted.

〔Effect of the invention〕

As described above, according to the present invention, the light from a single light source is changed in color into light corresponding to a predetermined cooking mode by the light changing member that works in conjunction with the cooking mode switching device and changes the color of the light. This variable light is emitted to the light display part of the pointer that indicates the power value or temperature value, so you can check the set amount of power or temperature value and the cooking mode at a glance just by looking at the position of the pointer. In addition, since fewer display elements are required, the product can be provided at a lower cost.
