ORIGINAL
COMPLETE SPECIFICATION STANDARD PATENT Invention Title: 9a .4 .Z 46 .tt .:.C-ti5C.7i?!C.L TO ti/B1 following statement is a full description of this invention, including the best *::..method of performing it known to me:- The purpose of this invention is to minimise damage caused by water escaping from a faulty electrical hot water tank.
Damage to property caused by water escaping from the hot water tanks can be substantial. According to insurance company's statistics, claims for damage caused by leaking hot water tanks comprise a large cost to their business.
There is no previous device to automatically cut off water and electricity supply to hot water tank. Prior to this invention, water and electricity supply to damaged hot water 0 tank had to be cut off manually. Therefore, if a continuous watch on the hot water tank is not kept and a leakage occurs, property would be damaged before the hot water tank is repaired.
These problems are overcome by the present invention which cuts off water supply and electrical power to a faulty water tank.
To assist with understanding of this invention, reference will now be made to the accompanying drawings: Referring to Fig. 1- it can be seen that the push-button type ":20 water valve 1 is locked in "on" position by lever 5 and spring 4 which are assembled on one of the sides of the water valve cover 3. The said cov r is made of heat resistant plastic or metal. In the locked position of the water valve, pin 8, located on said water valve button, activates micr switch 6 allowing electricity supply to the said water tank and said automatic device itself, Under normal operating conditions of the hot water tank, push-button water valve remains locked and allows the supply of water to said hot -2water tank. In presence of leaking water from said hot water tank referring to Fig. 2- sensors S1 (located at lower point of hot water tank) detects water. The electrical current from the sensor is delivered to the gate of the thyristor TR1. Said thyristor activates solenoid SRI, mechanically coupled to lever 5 Fig. 1, and releases the said push-button water valve whereby it cuts water and electrical supply to the hot water tank. The invention will be seen to be very simple.
Nevertheless, the result is an effective safety device. It will be seen that variations can be introduced, for example, utilising any other self-releasing type water valve instead of push-button type water valve as described above. However, these and other similar variations will be seen to lie within the scope of this invention.

Claims (3)
1. An automatic device to cut water and electricity supply to hot water tanks comprising a self-release type of water valve, a water valve locking device, a solenoid mechanically coupled to said locking device, and a water sensitive device operably connected to said solenoid; an electrical switch to cut electrical supply to said hot water tank and said solenoid; constructed and arranged whereby under normal said hot water tank operating conditions, the said water sensitive device does not detect presence of leaking water and therefore does not activates the said solenoid, thereby leaves the said locking device locked and the said water valve open, therefore allowing supply of water to the said water tank, electrical switch operably connected to the said water valve remains on, thereby allowing electrical supply to the said hot water tank, S and whereby under presence of leaking water from said hot water tank, the said S water sensitive device detects leaking water and activates the said solenoid which, releases the said locking device and thereby closing the said water valve, therefore cutting the water supply to the said hot water tank, closing of the said water valve operating the said electrical switch to cut the electrical supply to the said hot water tank.
An automatic device to cut water and electricity supply to hot water o o 20 tanks as claimed in claim 1 where water valve is locked in "on" position by lever mechanically coupled to solenoid.
3. An automatic device to cut water and electricity supply to hot water tank substantially as described in the specification with reference to the drawing. Dated this 17th day of June 1994. Alex Cheklin 7 Val Bekrr n Yana Bekman c-- Michael Gammer
