Abstract

(57) [Summary] (with amendments) [Purpose] Automatically turn on and off indoor electrical equipment to prevent forgetting to turn it off and help save power. [Structure] For example, it determines whether a person is currently in the room based on the opening/closing movement of the door when entering or exiting a room such as a toilet, and determines whether a person has entered the room by opening/closing the door for the first time. When this is determined, the indoor lighting system is turned on or the ventilation fan is operated, and when the door is opened and closed again and it is determined that the person has left the room, the lighting system is automatically turned off and the ventilation fan is stopped. make it possible to do so.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention applies to electrical appliances such as lighting devices and ventilation fans installed in rooms such as toilets. This invention relates to a power supply control device for indoor equipment that automatically operates the equipment.

0002

[Conventional technology]

Electrical products installed in houses, such as lighting installed in toilets When turning on and off electrical appliances such as equipment or ventilation fans, enter the toilet room. A switch for operating the above-mentioned lighting device and ventilation fan should be installed near the entrance. By operating the switch, you can turn on or off the lighting system in the toilet room, or turn on the ventilation fan. It was used to drive or stop the motor.

0003

[Problem that the idea aims to solve]

In this way, indoor electrical appliances are manually placed in the appropriate positions. Because the switch is operated to blink or start/stop, for example, it may not be used indoors. Forgetting to turn off the lighting equipment or turning off the ventilation fan can lead to uneconomical power usage. This may occur. Also, every time you go in or out of a room such as a toilet, the door will open and close, and the Turning on and off electrical equipment is an inconvenient task that requires manual effort. There was a coincidence.

0004

[Means to solve the problem]

The present invention was developed by focusing on such conventional problems. Currently, people are using the door opening/closing motion when entering or exiting the toilet. It determines whether a person is inside the room, and the first door opening/closing determines that a person has entered the room. If this occurs, turn on the indoor lighting system or operate the ventilation fan, etc., and then open/close the door again. If it is determined that a person has left the room, turn off the lighting equipment and turn off the ventilation fan. To improve the economy of electricity use by automatically stopping the The object of the present invention is to provide a power supply control device for indoor equipment that can perform the following functions.

[0005]

【Example】

The present invention will be explained in detail below based on the embodiment shown in FIGS. 1 and 2.

[0006] In Figure 1, 1 is a door switch that turns on and off each time the door is opened and closed, and 2 is a door switch that will be described later. manual switch for manually operating driving equipment such as lighting equipment or ventilation fans. It is Chi. 3 inputs the signal from door switch 1 or manual switch 2, In particular, whether a person entered the room or went outside after receiving the signal from door switch 1. A control device for determining the lighting device 6 and the lighting device 6 based on a signal from this control device. It is capable of blinking, driving and stopping driving equipment 5 such as a ventilation fan. 4 indicates a timer for setting the drive time of the drive device 5.

[0007] The above is the configuration of this embodiment, and the operation is explained in the flowchart shown in FIG. This section also explains the routes.

[0008] The door is closed when no one is in the specific room where the door switch is installed. When there is no door switch signal, the lighting device 6 and drive device 5 are switched off. It is in a blank state. When the door is opened to enter the room, the control device receives a door opening signal. As a result, the control device 3 causes the lighting device 6 and the drive device 5 to operate. At the same time that the signal is supplied and the illumination is turned on, the drive device 5 operates. then indoors When a person enters and closes the door, there is no change in the drive signal and the lighting and drive equipment remains operational. Next, the door is opened and closed again for the person to exit the room. Then, the control device outputs a turn-off signal for the lighting device 6 and a stop signal for the drive device 5. The lighting device 6 is immediately turned off, but the drive device 5 is turned off at a predetermined time by the action of the timer circuit 4. It will stop after the set time has elapsed.

[0009] In this example, the opening/closing movement of the door to enter and exit the room is The system determines whether a person is in the room or not, and determines that a person is (entered) the room. When this happens, the electrical equipment in the room is activated, and there is no one in the room (they left the room). When it is determined that the This allows electrical equipment to stop operating when no one is in the room. This increases the economical use of electricity.

0010

[Effect of the idea]

As described above, the present invention has a door switch 1 that detects the open or closed state of an indoor door. , receives a signal from the door switch and determines whether the person is indoors or outdoors. A control device 3 that controls the supply of current according to the judgment of the control device 3, and This is a power supply control device for indoor equipment consisting of indoor electrical equipment 6 and 7 operated by the current. This prevents people from forgetting to turn off the electrical equipment installed in the room, and saves money. Useful for electricity. In addition, the opening and closing of the door to enter and exit the room may cause the electrical equipment in the room to be Automatic switching on and off eliminates the need for manual switching operations Therefore, the effect of convenience can be obtained.
