Description
"Improvements relating to-Shower Water Supply"
Domestic hot water showers are well known to overheat the water if another appliance is used and this can lead to the person in the shower getting scalded. It is an object of this invention to provide a device for a shower unit which will reduce or eliminate this risk.
According to the invention there is provided a water supply control device having an inlet pipe for connection to a mains water supply, a main outlet pipe for connection to a domestic water system, and a secondary outlet pipe for connection to a shower unit, the main pipe incorporating a valve arranged to be actuated when flow occurs through the secondary pipe, to close direct supply to the domestic water system, and an adjustable flow restrictor connected between the secondary pipe and a point in the main pipe downstream of the valve.
Preferably the valve will be solenoid-operated (although any convenient electrical, mechanical or manual actuator could be employed) and controlled by a sensor, which registers flow through the secondary pipe or operation of a shower unit connected to the secondary pipe.
The valve system of the invention allows most of the water flow to be used by the shower and a lesser amount to be used by the other appliances. When the shower is turned on an electrical supply is sent to the valve operating the solenoid coil. This in turn allows most of the water flow
to the shower and causes a restricted amount of water to flow to the rest of the domestic system via the adjustable flow controller. The system could also be made to operate with standard flow regulators.
The solenoid operated valve and associated pipework can be fitted by a suitably qualified person into a domestic water system at a point before any other appliance or water user will draw off water. The main parts of the control device could be housed within the shower unit itself, when that unit is manufactured.
The connections can be of the compression type as commonly used in water systems or even could be push-fit fittings. The whole unit should be earthed as an electrical power supply is used to operate it. Ideally the valve assembly is totally enclosed with the exception of the inlet/outlet pipes and the electric cable to operate the solenoid valve.
A preferred embodiment of a water supply control device in circuit form will now be described by way of example with reference to the accompanying Figure 1 of the drawings.
As shown in Figure 1, the device comprises a solenoid coil 1, controlling a valve 2 and an adjustable flow restrictor 3. An enclosure 4 is provided for the solenoid coil and an electrical connection block/fuse holder 5.
In normal conditions (with the shower not operating) the water flows through the valve 2 from a mains supply
pipe 6 and is used in the domestic water system from the pipe 7. When the hot water shower is switched on the solenoid coil 1 is activated and causes the valve 2 to shut off the flow of water to the domestic system through the valve. The main flow of water is now directed through the pipe 8 to the hot water shower. Since hot water showers do not use all of the available water flow, excess flow is available for use in the domestic system. This excess flow can only get to the domestic supply via the adjustable flow restrictor 3 in the connection pipe 9. This flow restrictor 3 is set up and adjusted when the device shown in the drawing is installed. When the hot water shower is switched off the electrical supply to the solenoid coil 1 is switched off also, allowing normal supply of water to the domestic system to be resumed.
Claims (4)
1. A water supply control device having an inlet pipe for connection to a mains water supply, a main outlet pipe for connection to a domestic water system, and a secondary outlet pipe for connection to a shower unit, the main pipe incorporating a valve arranged to be actuated when flow occurs through the secondary pipe, to close direct supply to the domestic water system, and an adjustable flow restrictor connected between the secondary pipe and a point in the main pipe downstream of the valve.
2. A water supply control device according to claim 1, wherein the valve is solenoid-operated and controlled by a sensor, which registers flow through the secondary pipe or operation of a shower unit connected to the secondary pipe.
3. A water supply control device according to claim 1 or claim 2, wherein the valve assembly is totally enclosed with the exception of the inlet/outlet pipes and the electric cable to operate the solenoid valve.
4. A water supply control device substantially as herein described, with reference to the accompanying drawings.
