2. Description of the Related Art Conventionally, there has been disclosed, for example, Japanese Patent Laid-Open No. Sho 59-94 as a toilet flushing device which detects a user with a sensor and, when the user leaves, drives a solenoid valve by a control signal from a controller to discharge flush water. There is one described in Japanese Patent Publication No. 126831. This toilet flushing apparatus uses a battery as a power supply so that it can be installed even in a place where it is difficult to connect a 100-volt commercial power supply directly to the controller.

[0003]

However, the above-mentioned conventional toilet flushing apparatus uses a battery as a power source, so that the battery must be replaced after the consumption period has elapsed, and there is a problem in terms of maintainability.

Accordingly, in the present invention, a power unit provided at a place where a commercial power supply is easily connected transmits microwaves to the controller as power required for controlling the controller and driving the solenoid valve. Accordingly, it is a technical problem to be solved to eliminate the need for a battery and to improve the maintainability.

[0005]

Technical means for solving the above problems include a sensor for detecting a human body and outputting a human body detection signal, and a solenoid valve driven based on the human body detection signal from the sensor. An automatic cleaning device comprising a controller for automatically discharging the cleaning water.
A controller for controlling the controller and outputting a microwave serving as power required for driving the solenoid valve, while the controller receives the microwave and performs the control and the electromagnetic control. Another object of the present invention is to provide a configuration including a power supply conversion circuit for converting the driving power required for driving the valve.

[0006]

According to the above-mentioned automatic cleaning apparatus, when microwaves are output from the power unit, the microwaves are received by the controller, and the control and the electromagnetic valve are performed in the power conversion circuit of the controller. Is converted to the drive power required for driving the
It can be installed in places where it is difficult to supply commercial power such as 0 volt.

[0007]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a layout view of an automatic cleaning device installed in a urinal room to which a commercial power supply such as 100 volt is not connected. As shown in FIG. 1, the automatic cleaning device that discharges cleaning water to the toilet bowls 1 and 2 performs cleaning when sensors 3 and 4 that output signals when a user is detected are provided on upper wall surfaces of the toilet bowls 1 and 2 respectively. Installed. A control panel (controller) 6 for supplying a drive signal to an electromagnetic flash valve 5 for discharging cleaning water is mounted on the wall surface. Then, the control panel (controller) 6 transmits to the control panel (controller) 6 a microwave which serves as a control power supply necessary for the control panel 6 and a driving power supply required for driving the electromagnetic flash valve 5. Power unit PU is AC100
It is connected to, for example, an adjacent room to which a volt commercial power supply can be connected. Note that a microwave passage WH is opened toward the end of the wall W so that the microwave transmitted from the power unit PU is not blocked by the wall W. The control panel 6 is provided with a pyroelectric sensor (not shown) for detecting that a user has entered the urinal room.

No electric wires are connected between the sensors 3 and 4 and the controller 6, and the sensors 3 and 4 have no built-in battery as a power supply. For this reason, a microwave is output from the control panel 6, and the microwave is output to a sensor.
3 and 4 receive and directly detect, so that the sensors 3 and
4 power supply. When a user is detected, the signals output from the sensors 3 and 4 are output in the form of radio waves.

FIG. 2 shows a power unit PU and a control panel 6.
FIG. 3 is a block diagram showing a control system of sensors 3, 4 and an electromagnetic flash valve 5. As shown in FIG.
When the microwaves are transmitted from the power unit PU to the control panel 6, the microwaves are received by the power conversion circuit 6 P of the control panel 6 and necessary for driving the control power supply and the electromagnetic flash valve 5. Converted to drive power.
On the other hand, the control panel 6 and the electromagnetic flash valve 5 are connected by an electric wire, and a drive signal is output from the control panel 6 to the electromagnetic flash valve 5 when a predetermined condition is satisfied. The sensors 3 and 4 receive the microwaves output from the control panel 6 as power signals, while the user detection signals output from the sensors 3 and 4 to the control panel 6 include, for example, medium-wave and short-wave signals. Radio signals are used. The sensors-3, 4 and the control panel 6 may be connected by wire.

FIG. 3 is a block diagram schematically showing an internal configuration of the control panel 6 and the sensors 3 and 4. As shown in FIG. 3, the control panel 6 has the power supply conversion circuit 6P built therein, and also has a power supply circuit 6A for outputting microwaves serving as a power supply for the sensors-3 and 4, and an antenna 6B built therein. , Sensors 3 and 4 have built-in antennas 3A and 4A and power supply circuits 3B and 4B for receiving the microwaves and directly detecting and converting the microwaves to power supply power. The sensors 3 and 4 include memories 3C and 4C for storing a detection signal when a user is detected, and modulating the signal and converting the signal into a radio signal to transmit the antenna 3 to the antenna 3.
Modulation circuits 3D and 4D output from A and 4A are built in. On the other hand, the control panel 6 has a sensor in the form of a radio wave.

FIG. 4 is a flowchart showing the control operation of the automatic cleaning device. In this automatic cleaning device, a microwave serving as a control power supply required for the control panel 6 and a drive power supply required for driving the electromagnetic flash valve 5 is transmitted from the power unit PU to the control panel 6. . As shown in FIG. 4, first, the CPU in the control panel 6
Determines the presence or absence of a user in the toilet using a pyroelectric sensor (not shown). When it is determined that there is a user in the toilet, the control panel 6 transmits a microwave serving as a power source of the sensors 3 and 4 and also transmits a drive signal, and the sensors 3 and 4 detect the user. Of infrared or ultrasonic waves. Next, when it is determined from the detection signals from the sensors -3 and 4 that there is a user in one or both of the toilets 1 and 2, the toilet with the user is stored and the user leaves the toilet. And wait until there is no user signal.

On the other hand, when there is no user of the toilets 1 and 2 according to the detection signals from the sensors 3 and 4, the electromagnetic flash valve 5 is driven with respect to the toilet from which the user has been removed. A predetermined amount of water is discharged by the above-mentioned method to perform washing. Then, the memory indicating that the user of the toilet is present is changed to a state of not present.

[0013] When all the toilet users are in a state of absence due to the control routine as described above, the CPU in the control panel 6 transmits microwaves and drive signals to the sensors 3 and 4. Stop.

As described above, according to the present invention, a sensor for detecting a human body and outputting a human body detection signal, and a solenoid valve being driven based on the human body detection signal from the sensor, automatically In an automatic cleaning device equipped with a controller that discharges cleaning water, it is necessary for the controller to control the controller and drive the solenoid valve from the power unit installed in a place where commercial power is easily connected. Since the configuration is such that microwaves with high power are transmitted, there is an effect that a battery is not required and the maintainability can be improved.
