Electrical apparatus having control part

【0001】

[Technical field to which the invention belongs]

The present invention relates to an electric device having an operation unit, such as a washing machine, a dishwasher, a microwave oven, an electromagnetic cooker, and an automatic hair washing machine.

【0002】

[Conventional technology]

In an electric device such as a washing machine, information set and input by an operation unit is transmitted to a control unit, and the control unit drives and controls a load unit such as a washing motor based on this information. In this case, the operation unit is provided in a place in front of the upper surface of the washing machine where it is easy to operate, and the control unit is arranged on the back surface of the operation unit close to the operation unit and is connected to the operation unit via wiring. That is, the control unit is provided near the operation unit due to wiring.

【0003】

[Problems to be Solved by the Invention]

Therefore, there is a restriction that the control unit must be arranged in the vicinity of the operation unit, and the degree of freedom in design is poor. Further, if the vicinity of the operation portion is relatively easily exposed to moisture, there is a problem that attention must be paid to waterproof measures.

【0004】

The present invention has been made under such a background, and an object of the present invention is to provide an electric device having an operation unit, which has a degree of freedom in design or can easily take measures against moisture.

【0005】

[Means for Solving Problems and Effects of Invention]

The present invention for achieving the above object is an operation unit for inputting information, a load unit, and a control unit for driving and controlling the load unit based on input information set and input by the operation unit. In an electric device having an operation unit provided with the above, the operation unit is in a wireless state with respect to the control unit, is not supplied with power from the outside, and has no battery function, and the control unit is the operation unit. It is characterized in that input information based on the setting input operation in is received from the operation unit to drive and control the load unit.

【0006】

Here, the operation unit has a built-in piezoelectric signal generator, and the piezoelectric signal generator converts the signal of the input information corresponding to the operation by piezoelectric conversion at the time of the press setting input operation in the operation unit, and the control unit. Make a wireless call to.

【0007】

Alternatively, the operation unit has a built-in resonance circuit device, and this resonance circuit device is a signal of input information corresponding to the operation at the time of a setting input operation in the operation unit, and is a signal transmitted from the control unit. The resonated signal is transmitted to the control unit.

【0008】

The load unit includes a motor of a washing machine, a pump motor of a dishwasher, a magnetron of a microwave oven, a heating coil of an electromagnetic cooker, a pump motor of an automatic hair washing machine, and the like, and an electric device handles moisture.

【0009】

According to the configuration of the present invention, the operation unit is in a wireless state with respect to the control unit, and the control unit can be arranged at a free position of the electric device without being affected by the position of the operation unit. For example, it can be freely placed in a place that is not easily exposed to moisture.

【0010】

Further, since the operation unit is in a wireless state with respect to the control unit, it cannot receive power from the control unit. Here, it is conceivable to incorporate a battery in the operation unit, but it is troublesome to replace the battery each time the battery is exhausted.

【0011】

Thus, in the configuration of the present invention, the operation unit can transmit the input information to the control unit in a configuration in which the battery is not built in, and the troublesomeness of battery replacement can be eliminated.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. FIG. 1 is a perspective view showing an external configuration of a fully automatic washing machine according to an embodiment of the present invention. The fully automatic washing machine has a washing tub (not shown) built in the main body 1, and an opening / closing lid 2 is provided on the upper surface of the main body 1 with respect to the washing tub. An operation unit 3 for inputting driving information is provided in an easy-to-operate place in front of the upper surface of the main body 1.

【0013】

FIG. 2 shows the circuit of a fully automatic washing machine. The operation unit 3, the washing motor 4 which is a load unit, and the control unit 5 which drives and controls the washing motor 4 based on the input information set and input by the operation unit 3 are provided.

【0014】

The operation unit 3 is in a wireless state with respect to the control unit 5, does not receive power from the outside, and does not have a battery function. The control unit 5 has input operation information based on the setting input operation in the operation unit 3. Is received from the operation unit 3 to drive and control the washing motor 4.

【0015】

Specifically, the operation unit 3 has a built-in piezoelectric signal generator 6. The piezoelectric signal generator 6 includes a piezoelectric element 7 and a frequency transmitter 8 that operates by receiving electricity generated by the piezoelectric element 7, and corresponds to the key pressing operation at the time of key pressing setting input operation on the keyboard 9. The signal of the input information is piezoelectricly converted and transmitted wirelessly to the control unit 5.

【0016】

Alternatively, as shown in FIG. 3, which shows a circuit of a fully automatic washing machine according to another embodiment of the present invention, the operation unit 3 has a built-in resonance circuit device 10. In this resonance circuit device 10, a resonance circuit is formed at the time of setting input operation in the operation unit 3, and a radio signal that resonates with a radio signal transmitted from the control unit 5 and is a signal of input information corresponding to the key operation. Is returned to the control unit 5.

【0017】

In the above embodiment, the fully automatic washing machine is illustrated as the electric device of the present invention, but an electric device (which handles moisture) such as a dishwasher, a microwave oven, an electromagnetic cooker, and an automatic hair washer may be used. In this case, the pump motor in the dishwasher, the magnetron in the microwave oven, the heating coil in the electromagnetic cooker, and the pump motor in the automatic hair washing machine are the load units.
