Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an operation switch for an electric washing machine.

[Conventional technology]

In recent years, washing machines have come to be equipped with microcomputers, and their operation is controlled according to the contents programmed in the microcomputers in advance.

A control board 3 provided with various electronic components including such a microcomputer is housed under an operation panel 2 made of synthetic resin at the top of the outer box 1 of the washing machine, as shown in FIGS. 7 and 8.

The operation panel 2 above the control board 3
The push button piece 5 is integrally formed by notching the periphery leaving the connection part 4, and this push button piece 5 corresponds to the switch parts of the control board 3 [in the illustration, the washing switch 6a and the dewatering switch 6b]. I let it happen.

The upper surface of the panel 2 is covered with a name plate 7 made of a synthetic resin sheet on which the name of the switch is written, which also serves as waterproof protection.

In this way, when the push button piece 5 is pressed with a finger from above the soft plate 7, the push button piece 5 is bent downward by the pressing force, and each switch 6a, 6b is turned on or off.

By the way, the microcomputer controls the user by sounding a buzzer at the end of the washing process and the dehydration process, for example, but this is done by the timer function of the microcomputer acting upon receiving input from the switches 6a and 6b. A program is created that outputs an output to the buzzer at the end of the process. Since such a program is set up, the buzzer always sounds when the specified process is completed, and in order to stop the buzzer from sounding at the user's request, the wire to the buzzer must be disconnected, making it useless. Alternatively, it is necessary to separately provide a switch for inputting the stop of the buzzer.

Also, instead of providing a special switch component on the control board 3 in this way, it is also possible to input a special input using a method that is not normally used, for example, pressing the washing switch 6a and the dewatering switch 6b at the same time and using this as an input to stop the buzzer. .

[Problem that the invention attempts to solve]

By the way, when a special input is made by pressing two switches at the same time as described above, with the conventional operation switch shown in Fig. 6, the two pushbutton pieces must be pressed simultaneously with two fingers. However, it sometimes becomes unbalanced and cannot be used properly, making it extremely difficult to use.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
To provide an operation switch for a washing machine which can easily and surely operate two switch parts simultaneously to make a special input.

[Means for solving problems]

In order to achieve the above object, the present invention integrally forms a push button piece with a notch around the periphery leaving a connecting part on a panel above a control board on which electronic parts are installed, and connects this push button piece with the switch parts of the control board. In a washing machine operating switch that corresponds to The gist is that the end is inserted under each push button piece.

[Effect]

According to the present invention, when operating switch parts one by one in normal operation, if the push button piece corresponding to the switch part is pressed with a finger, as in the conventional case, the push button piece is bent downward through the connection part. The end of the oblong plate is pushed down and its lower surface comes into contact with the switch component to turn it on and off. Since the shaft attachment part of the other end of the horizontally long plate is located in the center, the other end of the horizontally long plate does not try to lift upward like a seesaw and touch the switch parts below.

On the other hand, when operating two switch parts at the same time as a special input, if you press the center of the oblong plate located between the push button pieces with your finger, the elastic shaft protruding from the panel will bend and bend, allowing each push button to be pressed. This is 2 because the left and right ends of the horizontal board are lowered at the same time, leaving the button pieces as they are.
Contacts multiple switch parts at the same time. Then, when you release your hand, the horizontal plate returns to its original horizontal state due to the elasticity of the shaft.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Fig. 1 is a perspective view showing one embodiment of the operating switch for a washing machine according to the present invention, and Fig. 2 is a longitudinal sectional front view of the same. be.

It is the same as the conventional example in that the push button pieces 5 are integrally molded by leaving the connection part 4 on the operation panel 2 and cutting out the periphery, but the present invention has two push button pieces 5 arranged in parallel as shown in FIG. . It was installed protrudingly.

On the other hand, as shown in FIG. 4, a horizontally elongated synthetic resin plate 10 is prepared in which a through hole 10b for the elastic shaft 9 is formed in a boss portion 10a at the center of the longitudinal side. and,
The horizontally long plate 10 is pivoted to the panel 2 by inserting the elastic shaft 9 into the through hole 10b. At this time, the left and right ends of the horizontally long plate 10 are inserted under each push button piece 5. I made it.

The surface of the operation panel 2 is covered with plates 7 made of synthetic resin sheets, and each plate 7 has one push button piece 5 under which a washing switch 6a is placed, as shown in FIG. part, the other push button piece 5
The part below which the dehydration switch 6b is located and the central part of the horizontally long plate 10 between them are each circled, and letters indicating the switch operations such as "Wash", "Buzzer off", and "Dehydration" are added to the sides.

Next, usage and operation will be explained.

FIG. 6 is a flowchart showing the operation. For example, if you do not want the buzzer to sound, a program is set up to simultaneously press the wash switch 6a and the dehydration switch 6b to give a command to the microcomputer to turn off the buzzer.

The central part of the long side of the horizontally long board 10, that is, the name board 7
When you press the part labeled "buzzer off" with your finger, the oblong plate 10 will be pushed down horizontally while curving the shaft 9, and the left and right ends will turn off the washing switch 6a.
and the dewatering switch 6b at the same time, and both switches are turned on at the same time. In this case, both push button pieces 5
remains as is.

As a result, the buzzer flag 1 is set in the microcomputer, and as a result, even if the washing process is completed or the dehydration process is completed, the buzzer does not sound under the condition of the buzzer flag 1.

Note that when you release your finger, the horizontal plate returns to its horizontal state due to the elasticity of the shaft 9, and its left and right ends are connected to the switches 6a and 6b.
move away from

Furthermore, in the same way, press the center part of the oblong plate 10 and turn on the washing switch part 6a and the dehydration switch 6b at the same time, the buzzer flag will be set to 0.
Therefore, the command not to sound the buzzer is canceled.

If you want to turn on only the wash switch 6a, press the push button piece 5 above it (left side in the figure), that is, the part where "Wash switch" is written on the name plate 7, with your finger, and the push button piece 5 will turn on. The connecting portion 4 curves downward, and this pushes down the left end of the horizontally long plate 10, and the back side of the horizontal plate 10 is pressed down to the washing switch 6a.
This turns on when it comes into contact with.

At the same time, the other end of the horizontally long plate 10 rises upward in a seesaw manner, and does not come into contact with the dewatering switch 6b, so that only the washing switch 6a is turned on.

When the finger is released, the push button piece 5 returns to the horizontal state due to the elasticity of the connecting portion 4, and the horizontally long plate 10 also returns to the horizontal state due to the elasticity of the shaft body 9.

In the same way, if you press the other push button piece 5 (on the right side in the figure), that is, the part where "Dehydration switch" is written on the name plate 7, with your finger, the other side of the oblong plate 10 will lower and only the dehydration switch 6b will be pressed. is turned on.

When each switch 6a, 6b is turned on individually in this manner, and the buzzer flag 1 is not set as described above, the buzzer sounds after the washing step and the dehydrating step are completed to notify the end of each step.

[Effect of idea]

As mentioned above, the operating switch of the washing machine of the present invention allows special input by turning on and off two switches at the same time with one pressing operation, and normal input by turning each switch individually on and off. This allows for improved usability compared to a system in which two pushbutton pieces must be pressed at the same time for special input.
