[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention automatically controls ON / OFF of lighting equipment such as a toilet room and ventilation equipment using a human body detection sensor and a timer, eliminates complicated ON / OFF operation, and at the same time contributes to power saving. It relates to lighting and ventilation control devices for toilet rooms.

[0002]

[Prior art]

 Ventilation fans and lighting in the toilet rooms of buildings used by a large number of people are generally turned on and off with a manual switch. Normally, the manager turns around and turns on the manual switch before work hours. It is turned off or turned off after working hours. For this reason, the ON operation is often kept during work hours and daytime. As another method, there is a system in which the ventilating fan and the illumination lamp are turned on and off by remote control from a central control room. Yet another method is to use a human body detection sensor that uses infrared rays, ultrasonic waves, etc. to detect when a user enters the room and turn on the ventilation fan and lighting, etc. It is already known that the user turns off when the user leaves the room.

[0003]

[Issues that the device tries to explain]

 When the manager makes a patrol and manually turns on and off, there is a problem in that the patrol is troublesome and power is wasted because it remains on during work hours and daytime. On the other hand, when performing ON / OFF control by remote control from a central control room or the like, it is necessary to wire for remote control, which has a drawback that the whole system becomes large and complicated. Furthermore, in the conventional method for automatically turning on and off the ventilation fan and lighting by using the human body detection sensor, the human body detection sensor detects the moving object and operates. Therefore, for example, if the user is sitting on the toilet seat of a Western-style toilet for a long period of time, the output of the human body detection sensor will turn off, and even if the user is present, the ventilation fan and lighting will be turned off. There was a drawback that it caused the malfunction by turning it off.

[0004]

[Means for Solving the Problems]

 The present invention has been improved and removed in view of the above-mentioned problems in the related art, and there is a user by continuing the ON operation of the ventilation fan and the illumination lamp for a set time after the OFF output of the human body detection sensor. Despite this, it is an object of the present invention to provide a lighting and ventilation control device for a toilet room, etc., which can prevent a malfunction such as an OFF operation and contribute to a power saving effect.

Therefore, the first means adopted by the present invention to solve the above-mentioned problems is a human body detection sensor for detecting the presence or absence of a user in a room and controlling ON / OFF of a ventilation fan and lighting equipment. And a timer for continuing the ON operation of the ventilation fan and the lighting fixture for a set time after the OFF signal of the human body detection sensor is output, and a lighting and ventilation control device for a toilet room and the like. The second means is to connect a lighting device and a ventilation device installed in a room and a switch circuit for ON / OF F control of these in series, and connect a relay contact circuit in parallel to the switch circuit. A sensor / relay circuit in which a lighting / ventilation circuit is formed and a human body detection sensor and a relay that is ON / OFF controlled by the human body detection sensor are connected in series, and the relay is set for a set time after the human body detection sensor is turned OFF. A lighting and ventilation control device for a toilet room or the like, characterized in that a timer circuit for turning on a contact circuit is connected in parallel to the lighting and ventilation circuit.

[0006]

[Action]

 In the present invention, after the human body detection sensor for ON / OFF control of the illumination lamp and the ventilation fan is turned OFF, the ON operation of the illumination lamp and the ventilation fan is continued for a predetermined time set by the timer circuit. There is. The above-mentioned set time is set by, for example, empirically finding the continuation time that the user may stay indoors when the bear does not move. Therefore, the illumination lamp and the ventilation fan are not controlled to the OFF state even when the user is in the room. Also, when the user is not in the room, the illumination lamp and the ventilation fan are automatically switched to the OFF state, so it is possible to reduce wasteful power consumption.

【Example】

 Hereinafter, the structure of the present invention will be described with reference to the drawings based on an embodiment of controlling an illumination lamp and a ventilation fan in a toilet room.

1 to 3 relate to an embodiment of the present invention. FIG. 1 is a diagram showing an electric circuit of a control device, FIG. 2 is a block circuit diagram of the same, and FIG. 3 is a human body detection in a toilet room. FIG. 4 is a plan view showing the arrangement of sensors and the like. As shown in FIG. 3, in this embodiment, ceiling-mounted human body detection sensors X1 and X2 as shown in FIG. 4 are provided on the ceilings of the men's and women's toilet rooms, respectively. ing. Further, a wall-mounted type human body detection sensor X3 as shown in FIG. 5 is provided on the entrance-side wall surface of the toilet room. On the other hand, lighting lamps L1 and L2 and a ventilation fan M are attached to the ceiling of the toilet room.

As shown in the block circuit diagram of FIG. 2, the control device of this embodiment connects the lighting / ventilation circuit 1, the sensor / relay circuit 2, and the timer circuit 3 in parallel. The circuit is configured. The lighting / ventilation circuit 1 includes lighting lamps L1 and L2 and a ventilation fan M mounted on the ceiling of a toilet room, a switch circuit 4 connected in series to the lighting fan M, and a relay connected in parallel to the switch circuit 4. And a contact circuit 5.

As shown in FIG. 1, the sensor / relay circuit 2 is connected in parallel with human body detection sensors X1, X2, X3 mounted on the ceiling and the wall surface of the entrance of the toilet room. A circuit in which the make contacts 25, 26, 27 of the human body detection sensors X1, X2, X3 and the relays R1, R2, R3 are connected in series is arranged in parallel with the human body detection sensors X1, X2, X3. They are connected to form a circuit.

The timer circuit 3 includes a circuit in which break contacts 6, 7, 8 of the relays R1, R2, R3 and a timer T are connected in series, a make contact 9 of the timer T and a self-holding relay Y. And a circuit in which and are connected in series, and both circuits are connected in parallel.

The lighting / ventilation circuit 1 connects the lighting L1 and the switch 10 in series, connects the lighting L2 and the switch 11 in series, and connects the ventilation fan M and the switch 12 in series. There is. Then, each of these series circuits is connected in parallel to the power supply. Further, the switches 10, 11 and 12 are respectively provided with make contacts 13 to 21 of the relays R1, R2 and R3 in the sensor relay circuit 2 and make contacts 22 to 24 of the relay Y of the timer circuit 3 in parallel. It is connected to the.

Next, an operation mode of the embodiment control device having the circuit configuration as described above will be described. First, when the user approaches the entrance of the toilet room, the human body detection sensor X3 detects it by infrared rays or the like. By this human body detection, the make contact 27 of the human body detection sensor X3 is closed and the relay R3 is turned on. Therefore, the make contacts 19, 20 and 21 are closed, and the break contact 8 is opened. When the make contacts 19 to 21 are closed, the illumination lamps L1 and L2 and the ventilation fan M are connected to the power source, and illumination and ventilation in the toilet room are automatically started. On the other hand, when the break contact 8 is opened, the timer T is reset.

From such a state, when the user enters the toilet room, the user deviates from the detectable area of the human body detection sensor X3, and the relay R3 is turned off. Therefore, the break contact 8 of the relay R3 is closed and the make contacts 19 to 21 are opened. Here, since all the break contacts 6 to 8 of the timer circuit 3 are closed by closing the break contact 8, the timer T is turned on and the make contact 9 is closed. As a result, the self-holding relay Y is turned on, the make contacts 22 to 24 are closed, and the illumination lamps L1 and L2 and the ventilation fan M continue to be turned on. This continuation is performed for the set time of the timer T.

However, in actuality, when the user further advances to the interior of the toilet room, the human body detection sensor X1 or X2 detects the user and turns ON, and the break contact 6 or 7 is opened. The timer T will be automatically reset during the time counting. Therefore, the timer contact 9 is opened, the relay Y is turned off, and the make contacts 22 to 24 are opened. On the other hand, the make contact 25 or 26 is closed by the ON operation of the human body detection sensor X1 or X2. Therefore, the relay R1 or R2 is activated and the make contacts 13 to 15 or 16 to 18 are closed, so that the ON operation of the illumination lamps L1 and L2 and the ventilation fan M is continued.

As described above, when one of the human body detection sensors X1, X2, and X3 detects the human body, or when the human body detection sensor X1 does not detect the human body until the time set by the timer T elapses, the illumination lamp L1, Illumination and ventilation by the L2 and the ventilation fan M are automatically performed. In other words, even when the user sits down on the toilet seat in the toilet room, the behavior of the limbs is stopped for a long time, and all of the human body detection sensors X1, X2, and X3 are turned off at the same time, the timer is used. Lighting and ventilation are performed during the set time of T. The set time of the timer T is obtained by, for example, calculating the time for the user to stop the behavior in the toilet room from the rules of experiment. Therefore, according to the control device of the present embodiment, it is possible to reliably prevent a malfunction that the illumination and ventilation are stopped during use. Of course, after the user leaves the toilet room and the set time of the timer T has passed, the illumination lamps L1 and L2 and the ventilation fan M are automatically turned off, and a power saving measure is taken. In the control device of this embodiment, it is also possible to turn on the switches 10 to 12 to individually control ON / OFF of the illumination lamps L1 and L2 or the ventilation fan M.

By the way, this school plan is not limited to the above-mentioned embodiment, and for example, the types of human body detection sensors, lightings and ventilation fans, and the number of installations thereof may be appropriately changed according to the place of installation. It is possible. In addition, the control device of the present invention can be applied to those that perform lighting and ventilation of rooms other than the toilet room.
