Abstract

PURPOSE:To allow a person with weak eyesight to easily judge and operate by generating sounds with different lengths in response to the operation of each output adjustment with a buzzer. CONSTITUTION:When a power supply touch switch section 6 is depressed, a current lamp is lit, a buzzer 10 generates a sound to inform that a power supply is turned on. When an output adjusting touch switch 8 is depressed, an output display lamp 9 at the depressed position is lit. The sound of the buzzer 10 generated by the depression of the switch section 6 and the touch switch 8 is converted by a sound length converting circuit 12 so as to have the different length according to each switch. Which touch switch section is depressed is understood by the change of the sound length without observing the display of LED or the like, and the output status can be grasped. A person with weak eyesight can thereby judge and operate easily.

Description

[Detailed description of the invention] Industrial applications The present invention is an induction heating cooker, open, stove.

This relates to cooking devices such as microwave ovens.

BACKGROUND OF THE INVENTION Generally speaking, it is difficult for visually impaired people to adjust the heat and output of heating appliances such as induction cooking appliances. In other words, since it is not possible to visually determine the position of the output adjustment knob, a concave-convex indentation or Braille markings have been placed around the sliding position of the knob for identification purposes.

Problems to be Solved by the Invention Incidentally, among the output adjustment mechanisms of recent heating appliances, adjustment mechanisms using electronic controls such as a set of touch keys are being adopted instead of conventional mechanical operations such as knobs.
In this case, it is difficult to notify the position of output adjustment based on the positional relationship of the knobs as in the past, making it unsuitable as an instrument for use by visually impaired people. Induction heating cookers, in particular, have been developed as safe cookers that can be used by blind people, taking advantage of their characteristics as heating appliances that do not emit flames, so there is a need for an easier-to-understand output adjustment mechanism.

The present invention aims to solve the above-mentioned problems and provide a heating cooker that allows even visually impaired people to easily perform operations such as output adjustment.

Means for Solving the Problems Technical means of the present invention for solving the above-mentioned problems: A device has a built-in buzzer circuit that generates sounds of different lengths when touched in response to each output operation. It is something.

Function In the above configuration, if the buzzer generates sounds of different lengths depending on the operation of each output adjustment, even visually impaired people can easily judge and operate. The shortcomings of can be overcome.

Example An embodiment of the present invention will be described below based on the drawings.

In FIG. 1, 1 is the cooking device main body, and the outer case 3
It is comprised of a cooking plate 2 on which a cooking pot is placed, and is equipped with a touch-type operation section 4. The operation unit 4 is composed of a panel 5 whose surface is made of a plastic sheet or a glass plate, and is an electronic control mechanism that turns the power on and off and changes the output by pressing or touching it with the user's finger. It is equipped with

FIG. 2 shows the operation section 4, and the panel 6 has a power supply touch switch section 6. Power lamp 7, output adjustment touch switch section 8. An output display lamp 9 that lights up corresponding to each touch switch is provided.

FIG. 3 shows a specific structure, in which a power supply touch switch 6 and an output adjustment touch switch 9 are arranged on the back side of the panel 6, and when these are pressed from the front surface of the panel 5, a buzzer 10 is activated. It is located inside 5. The buzzer 1o is configured to generate sounds of different lengths depending on the touch switches. Note that the buzzer 10 is held by a main body circuit board 11.

FIG. 4 shows a circuit diagram, in which A is the main circuit of a generally known electromagnetic induction cooking device, and B is a control circuit. The control circuit B includes an operation section 4, a tone length conversion circuit 12 that receives signals from each switch 6, 8, etc. in this operation section 4,
It also includes an output adjustment circuit 13 that receives signals from the operating section 4, and the output adjustment circuit 13 is connected to the input side of the main circuit A via a connector 14 such as a transformer. A buzzer 1o is connected to the tone length conversion circuit 12. 7 in the diagram,
9 is a power lamp and an output display lamp.

Now, the operation in the above configuration will be explained.

When the power touch switch section 6 is pressed, the power lamp lights up and the buzzer 1o sounds to notify that the power has been turned on. Next, when the output adjustment switch 8 is pressed, the output display lamp 9 at the pressed position lights up. Here, the sound of the buzzer 1o generated by pressing the power supply touch switch 6 or the output adjustment touch switch 8 is converted by the tone length conversion circuit 12 so that the length varies depending on each switch.

Therefore, depending on the change in the length of the sound, it is possible to know which touch switch part has been pressed without looking at a display such as an LED, and the status of the output can be grasped. This feature makes the touch switch easier to operate, especially for visually impaired people.

Effects of the Invention As is clear from the description of the above embodiments, the present invention allows the display unit to emit sounds of different lengths depending on the output operation etc. of the operation unit of a heating cooker, etc. The output position and operation position can be determined without looking, making it easier to operate touch keys, etc., which has a great effect on visually impaired people.
