BRIEF SUMMARY
DESCRIPTION
1. Technical Field
My invention relates to an electronic control apparatus, and, more particularly, to electrical control of water supply systems, and, still more particularly, to electrical control apparatus for water supply systems which include electrically controllable outlet valves and electronic circuit means to operate the outlet valves.
Still more particularly, my invention relates to electronic circuit means of a water supply system in which the circuit means receives an outside signal and transduces the signal to a proper signal within the system to direct the outlet valve to the proper state, either on or off.
Electronic or electrical components are incorporated within water systems for one or both of two basic purposes: for conserving water, or for the convenience of the user of the water system.
For the purpose of conserving water, a control device for a water supply apparatus usually assures the owner of the water supply apparatus, whether it is in a public area or in a residence, that water will be allowed to flow to the apparatus only when the water is necessary, and above all, that the supply will be cut off when the user has left the immediate area of the apparatus. As shown in some of the prior art cited below, there have been various controls employed for conserving water. Some of these controls involve the interruption of a light beam, some rely upon a change of inductance, or capacitance, caused by the approach of the user, to operate a main supply valve.
In those apparatus which are designed for the convenience of the user, again, the electrical or electronic control may be based upon a change in inductance, or capacitance, or upon a physical touch by the user other than a touch with his hands.
2. Background Art
Some of the typical electrical and electronic controls which might be employed for various purposes and in different types of water supply systems were found in the prior art among the following patents:
DISCLOSURE OF INVENTION
Therefore, the primary object of my invention is to provide a control device for a water supply system which is inexpensive, easy to manufacture, and easy to use.
Another object of my invention is to provide an efficient control device for a water supply system.
Still another object of my invention is to provide a control device for a water supply system which will conserve water.
Still another object of my invention is to provide an electrical control system for a water supply system such that the water supply may be turned on or off by the user without physical contact with the water supply system.
Still another object of my invention is to provide a water supply control device which will respond to an acoustic signal to control the on and off flow of water.
In summary, I have designed an electrical control device for a water supply system which will enable the user to control the flow of water as he deems necessary for his benefit, which includes for his comfort and convenience as well as for his saving of money by saving energy and water. The saving of energy is accomplished by controlling the flow of heated water.
I have also designed my control system so that the system may be easily and quickly installed in essentially any type of water system and that the system may provide an easy and simple means of controlling the flow of water by the user, whether he has a physical incapacity or whether he desires to control the water supply system because of any hygienic or sanitary consideration.
The prior art cited above illustrates some of the control systems designed to operate under various conditions and for various purposes. Some of these electrical controls operate in response to a mechanical impulse, some operate by interruption of a light beam, and others operate in response to the approach of a person, by either a change in inductance or change in capacitance.
As may be readily seen, a single type of electrical control system may be employed for different purposes. For example, an acoustic switch may be used for a burglar alarm s
