The receiving circuit 460 is composed of a filter, a rectifying / smoothing circuit, a comparator, and the like, and the oscillation frequency component is extracted and rectified and smoothed. After this, the transmission data signal is reproduced by comparison and shaping with a proper reference potential in the comparator.
This reproduced transmission data signal is a data output terminal 466.
Is output to the microcomputer in the main body washing control circuit 45 via. FIG. 10B shows the timing of the above communication operation and the outline of the signal waveform.

て洗浄を開始する。In this way, bidirectional communication of operation switch information and display information is performed between the operation display section 16 and the washing machine main body control section 17 at the same time when power is supplied. For example, when the user presses the operation switch for automatic operation, this information is transmitted to the microcomputer of the main body washing control circuit 45, and the microcomputer opens the water supply valve 41 according to a sequence programmed in advance by this and puts a specified amount of water. Then, the detergent is automatically added and the blades in the rotary tank are rotated by the electric motor 43 to start the cleaning.

止する。At the start of cleaning and rinsing, the lid opening sensor 44 detects the opening of the lid 7 in order to prevent water from being blown out due to the rotation of the blades in the rotary tank, and the user is warned by a display or a buzzer sound. At the start of dehydration, in order to prevent the danger of high-speed rotation of the rotary tank, the lid opening sensor 44 detects the lid opening and informs the user to close the lid 7 with a buzzer sound or the lid is closed. Stop the start of dehydration operation until. Particularly in the dehydration operation, the rotating tank rotates at a high speed, which is dangerous. Therefore, when the user opens the lid 7 by mistake, the lid opening sensor 44 detects this and stops the rotation immediately.

Power is supplied to 9 by electromagnetic induction, and the operation display unit 16 is operating. When the lid 7 is lifted and the doorway 4 is opened, the ferrite 94 and the ferrite 96 are displaced from the positions where they are opposed to each other. Therefore, the magnetic path formed when the lid 7 is closed is interrupted. As a result, power is not supplied to the power receiving circuit 39, and the operation display unit 16 stops operating. From the viewpoint of the power transmission circuit 100, this is equivalently equivalent to the load on the internal transistor 490 becoming extremely light (the alternating current flowing in the power transmission coil 97 becomes extremely small due to the switching).

A warning is given to the person to be displayed and a buzzer sounds to alert the user to close the lid. When the lid is opened during the dehydration process, the electric motor 43 is stopped in an emergency.

る。When the lid is opened, power cannot be supplied to the operation display unit 16 and bidirectional communication between the washing machine main body control unit 17 and the operation display unit 16 is possible. If the lid is closed and the automatic operation is started, the process up to dehydration is automatically completed thereafter, so this does not pose a problem in use. Further, since the lid opening detection circuit 501 detects the opening of the lid 7 by the user carelessly during the dehydration process or the like and stops the rotation of the rotary tank, the safety can be improved.
