Abstract
A shower installation includes as a shower heater, an instantaneous electric water heater with water supply pipes to the heater and from the heater to the shower and a control unit for activating the heater, the control unit being mounted on a wall adjacent the shower head and the heater positioned on the opposite side of the same wall. The control unit includes a manually operated switch, which may be an on-off or multi-stage switch, to activate the heater. Preferably the switch is in the form of a variable central device that allows the temperature of water at the shower head to be selected by acting on the heating element or by controlling the flow of water through the heater. <IMAGE>
Description
SPECIFICATION
Improvements in shower installations
The present invention relates to shower installations and particularly to installations of the so-called instananteous type where water for the shower is heated only as it flows.
In accordance with the invention, a shower installation utilizes a water heater separate from, and more preferably remote from, a control unit which incorporates a manually operable control or switch for activating the heater. The control unit, which may conveniently have a neat panel, is easily accessible by a user. The control unit can be mounted on or in a wall adjacent a shower head which receives water heated by the separate or remote heater connected thereto preferably by a small bore pipe. The control unit may further have a water flow control valve operated by a lever which regulates the water flow. The flow regulation may of itself control the temperature of the water of the spray emitted by the spray head. The separate water heater would be connected to the switch control of the control unit by a cable.Operation of the switch control can open a normally-closed valve in the heater to permit water to flow to the spray head. The heater preferably incorporates one or more heating elements actuated automatically by a pressure sensor or valve in the heater whenever flow occurs thereby ensuring that water is heated only when it is flowing to the spray head.
The switch control of the control unit can be a simple on-off switch or a multi-stage or a variable control device which permits selection of the water temperature, for example, by acting on the heating element or elements or by acting on the pressure sensor or valve in the heater.
The invention may be understood more readily, and various other features of the invention may become apparent, from consideration of the following description.
An embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawings in which:
Figure 1 is a schematic representation of an installation in accordance with the invention;
Figure 2 is a block schematic diagram showing controls associated with the installation.
As shown in Fig. 1, a typical bathroom 10 has a WC unit 11, a wash hand basin 12 and a shower 1 3. The shower 1 3 can be freestanding or incorporated with a bath and hence the reference numeral 50 denotes a shower base and the dotted line 51 denotes a bath. Cold water is supplied to the basin 1 2 and to the WC unit 11 via a pipe 14 and hot water is supplied to the basin 1 2 via a pipe 1 5 leading to a hot water storage vessel or cylinder 1 6. The cylinder 1 6 is located in an airing cupboard 1 7 and cold water is supplied to the cylinder 1 6 by way of a pipe 1 8 leading to a cold water storage tank 19.A water mains supply pipe 24 feeds the storage tank 19.
The shower 1 3 is composed of a control unit 20 which incorporates a flow regulation control valve 51 operated by a lever 53 or likewise and a control 52 in the form of an on-off switch. An adjustable spray head 25 is connected to a pipe 23 which receives heated water from a heater 24. The spray head 25 may be connected by means of a flexible pipe 26 via the valve 51 to the pipe 23. Alternatively a pipe mounted in a wall 22 on which the unit 20 is mounted can connect the spray head 25 to the valve 51. The unit 20 has a control panel 28 with the control switch 52 and lever 53 accessible to a user. The unit 20 can be flush or suface mounted to the wall 22. The heater 24 is remote from the bathroom 10 and in mounted in this example on the other side of the wall 22 to the control unit 20.The heater 24 is provided with one or more electrical heating elements for heating water, a pressure sensitive valve for controlling the heating element or elements and a flow control valve operated by means of the switch 52 on the control panel 28. Water is supplied to the heater 24 by means of a pipe 38 leading to the main feed pipe 24.
The electrical power for energising the heating element(s) is supplied by a cable 35 which is connected via a simple pull switch 36 in the bathroom 10 to a fuse box 27.
Providing the switch 36 is actuated, a user can operate the switch 52 on the control panel to actuate the flow control valve of the heater 24 to cause water to flow from the pipe 38 through the heater 24 and the pipe 23 to the shower head 25. This flow of water is detected by the pressure sensitive valve in the heater 24 and this flow operates the heating element or elements.
The flow control valve 51 of the control unit 20 can be set to vary the flow rate of the water thereby to control the temperature of the water emitted by the spray head 25.
Instead of a simple on-off switch 52 on the control panel, it is possible to have a pre-set or variable control which controls the temperature of the water supplied to the pipe 23 independently of the flow control provided by the valve 51.
The heater 25 can be sited in positions other than that shown so long as it is unobtrusive and preferably outside the bathroom 10 or at least the shower area. For example, the heater 24 can be located in the loft space 30 as depicted in dotted lines.
Fig. 2 shows one possible arrangement for the controls wherein the pressure-sensor of the heater 24 is denoted 60, the flow control valve of the heater 24 is denoted 65 and a heating element is denoted 61. The dotted line depicts the modified system where the control 52 has a multi-stage switch 63 or a similar variable control which acts on a device 64 which varies the current flowing through the heating element 61. A temperature-sensor 66 can sense the temperature of the heated water and can interact with the switch 63 and the device 64 to maintain the temperature at a desired setting.
Claims (11)
