Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention quickly detects water leakage from electric equipment, water leaks into buildings, etc., and, if necessary, reports water leakage to a distant place, shuts off power to electric equipment, The present invention relates to a water leak detection and notification system that can easily add or remove a function such as shutoff of water supply.

[0002]

2. Description of the Related Art Conventionally, a water leak detection and notification system for a computer or a precision instrument in a business office or factory requires wiring work for installation, and has functions that are troublesome and unnecessary. Were also expensive, and public awareness was low. Therefore, besides notifying the detection result with a buzzer or alarm lamp blinking, it is not possible to easily add a function to shut off the power supply and water supply of the equipment at the same time.Therefore, electric washing machines, dishwashers, tropical fish that use water Most homes equipped with various housing equipment, such as water tanks, were largely unprotected.

[0003]

The problem to be solved by the present invention is to provide a system which is easy to handle and does not require, for example, wiring work, and which eliminates all unnecessary functions on site and has only necessary functions. Make it easy to assemble. For example, when a water leak is detected, not only is the warning lamp flashing or a buzzer sound displayed, but also the power supply of the electrical equipment and the water supply electromagnetic valve are automatically shut off at the same time to stop the water leak securely,
Even if it is necessary to notify a remote location, all the functions can be easily set up.On the contrary, if the alarm lamp blinks or the buzzer alone is sufficient, all unnecessary functions are removed. , The number of units that make up the system can be reduced, and the price of equipment can be significantly reduced.
Another object of the present invention is to provide a system in which each function can be easily added individually as needed even later.

[0004]

As a means for solving the above problems, a unit system can be considered. As shown in FIG. 1, each unit is plugged in with the main controller at the center. That is, the unit including the signal determination unit 21, the control output unit 22, and the display unit 23 is defined as the main controller 2 and can be plugged in to a power outlet.
Each unit, that is, the water leak detection sensor 1, the transmitting means 3, the monitored device 5, and the water supply electromagnetic valve 6 can be plug-in connected to the main controller 2. Of course, there may be cases where an intermediate adapter is needed for the connection. The receiving means 4 is installed at a remote place, and is constituted by a receiver 41 and an alarm output means 42.
Thus, there is no need for wiring work to the main controller, just plug in the necessary units for realizing the functions and do not assemble other units, and that has no effect on the required functions Anyone can easily handle it by not giving it. If necessary, add only that unit. That has no effect on others.

Next, the relationship between the units will be described with reference to FIG. 1. As the water leak detection sensor 1, a small spot sensor that can detect a spot and a cable sensor that can cover a relatively long section are selectively used according to the situation. In each case, a change in the electric resistance caused by water entering a small gap between the two insulated electric conductors is sent to the next signal determination means 21. The control output unit 22 shuts off the power of the monitored device 5 and shuts off the water supply electromagnetic valve 6, and the display unit 23 notifies the user by a buzzer and an alarm lamp blinking. The buzzer and alarm lamp blinking functions can be turned on and off in advance as necessary. On the other hand, the transmitting means 3 which has received the signal indicating that there is a water leak sends a signal to the receiving means 4 and the alarm lamp blinks via the alarm output means 42 from the receiver 41,
A buzzer informs you.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment of the present invention will be described with reference to the block diagram of FIG. 1 based on the configuration of all units. When it is determined from the change that there is water leakage, a signal indicating that there is water leakage is sent to the control output means (22) and the transmission means (3). In the control output unit 22, the power supply of the monitored device 5 and the water supply of the water supply electromagnetic valve 6 are set in advance, and at the same time, there is a buzzer notification of the display unit 23 and a notification of the presence of water leakage by an output such as blinking of an alarm lamp. do. On the other hand, the signal sent to the transmitting means 3 is carried on a radio wave and the receiver 4 of the receiving means 4 installed at a position away from the main controller.
1 and is informed of a water leak by buzzer notification, warning lamp blinking, etc., which are selected and set in advance via the warning output means 42. The above functions are all operated, and only the necessary functions may be selected to configure the system.

FIG. 2 is a perspective view showing an example in which this system is attached to an electric washing machine 7 and used. When the water leakage detection sensor 1 detects water leakage, the main controller 2 is turned on.
Processes the signal and simultaneously shuts off the water supply electromagnetic valve 6 and the monitored device 5, that is, the electric washing machine power supply to stop the water supply, and at the same time, the receiver 41 in which the transmitter 3 is installed at a place away from the signal.
The buzzer and alarm lamp blink to notify of water leakage.

[0008]

According to the present invention, anyone can easily and inexpensively obtain a water leak detection and notification system having a desired function because of a plug-in system using a unit for constructing the system. No wiring work is required for installation, and it is easy to add functions if necessary. It can be widely used for everything from buzzer alarm to remote alarm, automatic water supply shutoff, and power shutoff, and it is easy to construct multiple systems. Therefore, it can be used from general households to large factories.

Specifically, according to this system, it is possible to quickly detect water leakage, and if water supply to the equipment itself is the cause, water supply is immediately performed, for example, by shutting off an electromagnetic valve or power supply. Emergency measures can be automatically given to stop operation, etc., and damage can be minimized. In the case of water leakage due to an external cause, the information can be known even at a remote position, so that it is possible to promptly perform a response process.
