BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a touch-type operation section, and more specifically, the push-button section to be touch-operated is made sufficiently larger than the area of the fingertip and the push-button section is bent and deformed behind the push-button section. With regard to the structure of the touch-type operation section in which a plurality of switches to be turned on are arranged, more specifically, in such a structure, it is intended to enhance the operability by aligning the pressing operation force no matter which part is pressed. It is related to technology.

2. Description of the Related Art Recently, kitchen appliances have various functions, and their operating parts also have many push button parts. Since each push button portion is used so that the user looks down at the line of sight from above, the push button portion naturally becomes vertically long. In this way, even though the push button part is vertically long, the switch behind it can be turned on no matter which part of the vertically long push button part is pressed. A plurality of switches to be turned on are arranged electrically in parallel, and the push button portion is sufficiently flexibly deformed at the pressing portions corresponding to the plurality of switches.

[0003]

However, in such a structure, as shown in FIG. 5, a cut groove 4 is formed in the push button portion 1 and the uncut portion 5 is flexibly deformable. In the pressing points 1a and 1b, the pressing points 1a and 1b are independently bent and deformed. A crosspiece e exists between the pressing points 1a and 1b, and when pressing the crosspiece e, it is not necessary to press either of the adjacent pressing points 1a and 1b. Since it requires a pressing force, it is difficult to accurately turn on the switch S, it is difficult for an elderly person to operate, and a large operation force is required, there is a problem that operability is significantly reduced and the commercial value is also reduced. It was In the figure, reference numeral 6 denotes an operation sheet made of a soft synthetic resin, and although not shown, the operation content is represented on the operation sheet 6 by letters or pictograms.

The present invention is intended to solve such a problem, and an object of the present invention is to provide a plurality of pressing points on the push button portion and to arrange a switch on the back of the push button portion while adjoining them. Even when pressing between the pressing points, these adjacent pressing points can easily be bent and deformed,
A touch that can be surely turned on without needing to turn on the switch, and requires no operating force, and which can improve the operability and enhance the commercial value of the touch, by making the operating force the same and the operation feeling uniform. It is to provide the structure of the expression operation unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The touch type operation unit A of the present invention is used for, for example, a gas appliance C of a kitchen equipment, and the touch type operation unit A is made sufficiently larger than the area of the fingertip.
As shown in Figure 4, boiling water, boiled food, fried food, cooked rice,
When a character such as rice porridge is displayed and any desired portion of the touch-type operation unit A is touch-operated during cooking, the switch S on the back is turned on and a solenoid valve (not shown) is operated to set a predetermined value. The gas having a flow rate of 10 is supplied to the gas appliance so that desired cooking can be performed with a predetermined heating power. The configuration of the touch operation unit A will be described in detail below.

FIG. 1 (b) shows a side view, and FIG. 1 (a) shows a substrate 2 from which an operation sheet 6 has been removed, in which a kerf 4 is formed in a substrate 2 molded of synthetic resin. The push button portions 1 connected by the uncut portion 5 can be elastically displaced by a touch operation. This push button portion 1 is formed sufficiently larger than the area of the fingertip, and in the embodiment, five push button portions 1 are arranged in parallel. The wiring board 8 has screws 9 on the board 2.
And the switch S is attached to the wiring board 8. Then, the switch push rod 7 is projected backward from the push button portion 1 and the switch S can be turned on by the switch push rod 7 by pushing the push button portion 1.

The push button portion 1 is connected to the substrate 2 so as to be flexibly deformable at the uncut portion 5 in which the cut groove 4 is formed with respect to the substrate 2. In the push button portion 1, the pushing portions 1a, 1b and 1c are formed, and the switch push rod 7 is projected to the back of these pressed portions 1a, 1b and 1c, respectively. In this case, the pressing points 1a, 1b, 1c
Has a substantially rectangular shape at the facing L-shaped kerf portions 4c, 4c.
It is surrounded by In this way, in the plurality of pressure points 1a, 1b, 1c corresponding to each switch S, the adjacent pressure points 1a, 1b; 1b, 1c are communicated with the kerf 4 and the adjacent pressure points 1a, 1b;
1b and 1c are formed so that they can be pressed and deformed together. Specifically, the substantially C-shaped cut grooves 4b are vertically spaced from each other,
A vertically elongated substantially C-shaped communicating cut groove 4b is formed so as to face the two substantially C-shaped cut grooves 4a.

An operation sheet 6 is adhered to the surface of the substrate 2, and the operation sheet 6 is attached to the operation sheet 6 as shown in FIG.
Display such as boiling water, simmering, fried food, cooked rice and porridge is provided, and the operation sheet 6 is attached to the substrate 2. The switch push rod 7 on the board 2 corresponds to the switches S ₁ ... S ₅ on the wiring board 8. As described above, the push button portion 1 is flexibly connected to the substrate 2 at the uncut portion 5 in which the cut groove 4 is formed with respect to the substrate 2, and is connected to each switch S at a plurality of pressing portions 1a in the push button portion 1. , 1b, 1c, a series of cut grooves 4 are formed over the adjacent pressing points 1a, 1b; 1b, 1c so that the adjacent pressing points 1a, 1b; 1b, 1c can be pressed and deformed together. Then, even in the pressing operation, even if the adjacent pressing points 1a, 1b; 1b, 1c are pressed, the adjacent pressing points 1a, 1b; 1b, 1c can be flexibly deformed. In this way, even if the pressing points 1a, 1b, 1c are pressed, the switch S is turned on with substantially the same operating force, and anyone can easily and surely operate without causing unevenness in the operating force. , The operability thereof is greatly improved, and it is particularly effective for kitchen equipment, for example, where the eyes are used vertically, and the commercial value thereof is increased.

The shape and form of the kerf 4 in the present invention can be modified in various ways. Further, in the present invention, the switches S ₁ , S ₁ and S ₁ are grouped into one group, and the switch S 1
₂ ... as one group, as one group of switches S ₃ ·, switches S ₄ and ... as one group, and the switch S ₁ · · in the group switch S ₅ ... as a group Are connected in parallel to activate one device such as one solenoid valve regardless of which switch S ₁ ··· in the group is pressed, but the adjacent switches S ₁ , S ₁ ··· are operated. Each switch S ₁ is electrically independent and connected to a device such as a solenoid valve, so that adjacent pressing points 1a, 1b; 1b, 1c
Between the adjacent pressing points 1a, 1b; 1
b and 1c are operated together, and the switch S facing them is operated.
_The operation mode may be such that ₁ and S ₁ are activated to perform two functions by one pressing operation.
