Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a cordless type transmitter / receiver for a toilet in-room indicator light.

[0002]

[Prior art]

 Conventionally, various types of indicator lights have been proposed and put into practical use for indicating that a toilet is in the room. Conventionally used ones are provided with a magnetic or contact switch for an indicator light that is electrically connected to a lock lock of a toilet door, and at the same time as locking the lock lock, a magnetic or contact switch of the indicator light. Switch is turned on and an electrically connected indicator light remote from the toilet is added to indicate that the operator is in the room, while the lock is unlocked at the same time. When the magnetic or contact switch is turned off, the application to the indicator light is stopped and the indicator light indicates that the toilet is empty.

Recently, a non-contact type human body detection / identification means for detecting the presence of a person connected to an external power outlet is provided in the toilet, and when the person enters the toilet, the human body detection / identification means is provided. Is detected by, and a short-wave signal directed to the indicator lamp is transmitted continuously. This short-wave signal is received by the indicator lamp that is remote from the toilet and connected to the external power supply outlet, and the indicator lamp is turned on to continuously indicate that the indicator lamp is in the room. On the other hand, at the same time when a person exits the toilet, the short-wave signal transmitted from the human body detection and identification means to the indicator light is stopped, and the indicator light indicates that the toilet is empty. There is.

As the detection means used for this purpose, a human body detection / identification means generally called a heat ray sensor for detecting a slight temperature change due to the approach of a person, or an infrared ray emitted from a light emitting diode is used. There is known a human body detection / identification means generally called an infrared sensor for detecting the presence of a person by receiving the reflected light.

[0005]

[Problems to be solved by the device]

 However, the power supply of the conventional transmitter / receiver for the toilet in-room indicator light that uses such a non-contact type heat ray sensor or infrared sensor uses the commercial electricity via the external power outlet, and therefore the equipment is not installed. Construction costs were high, and once installed, it was troublesome to change the installation location, and there was the inconvenience that the construction had to be done by a specialist.

Further, if the human body detecting and identifying means provided in the transmitter for the toilet in-room indicator light is a heat ray sensor, the heat ray sensor detects and recognizes a slight temperature change, so that a person stands still and the temperature is detected. When the change stabilizes, the short-wave signal that was continuously transmitted from the human body detection and identification means to the indicator light is stopped.Therefore, even if the toilet is in the room, the indicator light has a toilet. There was a problem that was displayed.

Further, in order to easily respond to heat other than human body temperature represented by direct sunlight or reflected light from glass, for example, a short-wave signal is transmitted in response to heat other than human body temperature. If this happens, the indicator light will turn on even when there are no people, and the indicator lamp will indicate that the toilet is in the room. It was

On the other hand, when the human body detection / identification means is an infrared sensor, the infrared sensor receives the reflected light of infrared rays emitted from the light emitting diode to detect and identify the presence of the person, so that the person is completely stationary. If you move a little without doing this, the amount of reflected infrared rays will decrease, so that the short-wave signal that was being sent from the human body detection and identification means to the indicator light will be stopped, and the toilet will be in your room. Even then, there was a problem that malfunctions such as the indication on the indicator light indicating that the toilet is empty.

In addition, if the infrared sensor alone is used to detect the entry / exit of a person, the power consumption will be enormous because it is necessary to continuously emit infrared rays. If the battery is used as a power source, the amount of stored electricity will be consumed in a very short period of time, so it will be necessary to frequently replace the battery while constantly monitoring the life (charge storage amount) of the dry battery, which is very troublesome and inconvenient. there were. Therefore, since the power source used had to be commercial power source, the facility construction cost was high, and once installed, it was troublesome to change the installation location, and the construction work had to be done by a specialist. There was also a problem.

Further, since it responds to light such as reflected light from glass or direct sunlight, there is also a problem that a short wave signal is erroneously transmitted in response to such light.

The present invention has been made in view of such circumstances, and an object of the present invention is to accurately and surely display the status of presence of a toilet in a room and to use a commercial power source as a power source. (EN) It is an object to provide a cordless type transmitter / receiver for a toilet in-room indicator light.

[0012]

[Means for Solving the Problems]

 Means for achieving the above object is as follows. The device of claim 1 is "a human body detection and identification means 11 for detecting and identifying that a person is in a toilet, and the human body detection and identification means 11". A transmitter 10 configured to include a transmitting device 12 for transmitting the identified information as a short-wave signal, a receiving device 22 that receives the short-wave signal transmitted from the transmitting device 12, and detection of the receiving device 22.

According to a second aspect of the present invention, “a human body detection and identification means 11 for detecting and identifying that a person is in a toilet and the information detected and identified by the human body detection and identification means 11 is transmitted as a short-wave signal. In a transmitter 10 configured to include a transmitting device 12 for operating the human body, the human body detection / identification means includes both a thermal sensor for detecting and identifying a person's movement and an infrared sensor for detecting and identifying a person's stationary state. And the electronic switch of the infrared sensor is operated by being applied by the detection output of the heat-sensitive sensor.

[0014]

[Embodiment of device]

 The present invention provides a transmitter / receiver device for a toilet in-room indicator light, for example, a transmitter 10 installed in a toilet located away from a place such as a party venue or a pub snack, and a receiver installed in the party venue or shop. Twenty and 20 are paired.

The transmitter / receiver for a toilet in-room indicator light of the present invention includes a human body detection and identification means 11 for detecting and identifying that a person is in the toilet, and this human body detection and identification means 11 for detection and identification. A transmitter 10 (FIG. 1) including a transmitter 12 for transmitting the generated information as a short-wave signal, a receiver 22 for receiving the short-wave signal transmitted from the transmitter 10, and the receiver 22. It is a cordless type transmitter / receiver for a toilet occupancy indicator lamp, which comprises a receiver 20 (FIG. 2) configured to include a toilet occupancy indicator lamp 21 which is operated and turned on by the detection output.

The human body detecting / identifying means 11 mounted on the transmitter 10 of the transmitter / receiver for a toilet in-room indicator light according to the present invention mainly detects a heat sensitive sensor for detecting a person's movement, and mainly detects a person's still state. It is composed of both an infrared sensor, and the electronic switch of the infrared sensor is configured to be operated by being applied by the detection output of the heat sensitive sensor. Further, the transmitting device 12 is detected by the human body detection and identification means 11. It is composed of a radio wave generation circuit 12a for converting the separated information into a short wave signal and an antenna 13 for transmitting the short wave signal.

First, the operation of the transmitter 10 will be described. When a person enters the toilet, the movement of the person at this time is detected and identified by the heat sensitive sensor, and then the electronic switch of the infrared sensor is turned on by the detection output of the heat sensitive sensor. In this state, the infrared sensor operates, and then a short wave signal is transmitted from the antenna 13 via the radio wave generation circuit 12a which is applied with the output voltage of the infrared sensor. The wavelength of the short-wave signal (electromagnetic wave) transmitted via the radio wave generation circuit 12a can be variably set so as not to be crossed with each other even if a plurality of toilet emitting / receiving device for in-room indicator light are closely arranged. It has become.

The receiver 20 of the toilet in-room indicator light emitting / receiving device of the present invention is arranged at a position separated from the toilet, and detects the information transmitted by the human body detection / identification means 11 as a shortwave signal. The receiving device 22 for receiving and the toilet in-room indicator light 21 are included. The receiving device 22 includes an antenna 23 and a radio wave receiving circuit 22 a for converting the short-wave signal received by the antenna 23 into an output voltage. The toilet in-room indicator light 21 includes a lighting inverter 26. And a fluorescent tube 21a and a light emitting plate 21b.

When the short-wave signal transmitted from the transmitter 10 is received by the antenna 23, the relay of the radio wave receiving circuit 22a is activated, and then the lighting inverter 26 is applied by the output voltage thereof so that the position is easily noticeable. The fluorescent tube 21a provided in the toilet in-room indicator light 21 attached to the lamp is turned on. Therefore, it is silently understood that many people, except those who are in the toilet, have the toilet.

Next, the operation after using the toilet will be explained. First, the movement of the person who is leaving the room is detected and identified by the heat-sensitive sensor, and the electronic switch of the infrared sensor is turned off by the output voltage of the heat-sensitive sensor. The transmission of the short-wave signal that had been transmitted stops, and the relay in the receiver operates in the opposite manner to turn off the toilet in-room indicator light 21. Therefore, for many people, the toilet I can silently understand that there is a vacancy.

A heat-sensitive sensor that consumes less power is used to constantly detect and identify the movement of people into and out of the toilet, and the infrared sensor that consumes much power is not operated when there is no person in the toilet. Therefore, it is possible to significantly reduce power consumption, dry batteries (including rechargeable bittery) can be used as a power source instead of commercial power, and the transmitter / receiver can be of a mobile type. Therefore, it can be easily installed without the need for professional work in a simple toilet that is installed in a place where commercial power cannot be used, such as in an evacuation area in an area affected by a disaster such as an earthquake or typhoon. Can and can move.

Further, since the thermal sensor is used for constant detection, for example, when the transmitter 10c is installed on the ceiling of a toilet with a height of 3 m, the effective detection range is the floor surface as shown in FIG. Is a 1 mx 3 m rectangle, and the effective detection range of the detection identification means is wide. Therefore, for example, the ceiling surface (10c) in the toilet, the left and right side wall surfaces (10a), and the front wall surface (10b) can be freely arranged at any desired position. it can.

The transmitter 10 according to the second aspect of the present invention is the same as the transmitter 10 described in the first aspect of the present invention, and operates in the same manner as the transmitter 10 described above. Therefore, the description thereof will not be repeated.

[0024]

[Effect of device]

 As described above, the human body detection / identification means mounted on the transmitter of the toilet in-room indicator light transmitter / receiver of the present invention mainly detects the motion of the person and the stationary state of the person. In addition, the electronic switch of the infrared sensor is configured to operate by the detection output of the thermal sensor. In addition to the function and effect of the device, it has the following remarkable function and effect.

(1) Even if a person stops moving when the toilet is in the room and is in a stationary state, and the operation of the thermal sensor becomes unstable, or even if the thermal sensor cannot detect and detect it, the infrared sensor operates and detects it. Since the identification is continued, there is no malfunction that the indicator light indicates that the toilet is empty while the toilet is in the room. It is possible to reliably avoid malfunctions such as those displayed when there is an error.

(2) Since the thermosensitive sensor is used for constant detection, the effective detection range of the detection and identification means is wide, and it can be attached / detached to / from any desired position, for example, on the ceiling or sidewall of the toilet. It can be arranged freely.

(3) In addition, a heat-sensitive sensor that consumes less power is used to constantly detect and identify the movement of people into and out of the toilet, so that the red line sensor, which consumes a lot of power, will not operate when there is no person in the toilet. Since it is configured to, the power consumption can be significantly reduced, and dry batteries (including rechargeable bittery) can be used as the power source instead of the commercial power source, and the transmitter / receiver can be made mobile. .

(4) Therefore, there is no need for construction by a specialized company in a simple toilet installed in a place where commercial power cannot be used, such as in an evacuation site in a disaster-stricken area such as an earthquake or typhoon. Easy to install and move.

(5) Further, since the indicator lamp is located at a remote position, a fashionable item can be used, which is also a decoration in a store, for example.
