Abstract
Apparatus for use in removing water from a shower tray comprises an elbow joint 15 positionable above the base of a shower tray 12 to provide a clearance between the base and an end of the elbow, the apparatus further comprising means for producing suction at the end of the elbow adjacent the base of the shower. There is also provided a shower tray having a recessed portion in place of a conventional drainage hole, and a suction pipe having a first, suction end extending towards the base of the shower tray, wherein a clearance is provided between the suction end of the pipe and the base of the shower tray. <IMAGE>
Description
IMPROVEMENTS IN OR RELATING TO WATER REMOVAL
The present invention relates to an improved method of and apparatus for draining water from areas such as showers.
Conventionally, to drain water from a bath or shower, a ptrap is provided below a drainage hole formed in the base of the bath or shower. In general. only a very small clearance is available between the base of the bath or shower and the floor upon which it will rest. Accordingly, at least a portion of the p-trap or the waste pipe leading from such a p-trap has to be below floor level. When installing a bath or shower, this requires lifting of the floor boards, or where installation is above a concrete floor it requires a channel to be made in the concrete floor in to which the waste pipe and p-trap may fit. This problem arises particularly in providing a shower for an elderly or disabled person when conventionally a level access shower tray is provided.Such trays are provided without an outer rim on one edge of the tray which otherwise would present an obstacle to persons of limited movement endeavouring to enter the shower area. Such trays are provided with an inclined floor. gently sloping towards a drainage-hole and often provided with a ramD to allow easier entry to the shower particularly for a wheelchair-bouna person. Accordingly, level access shower trays present a further reduced sub-trays area for installation of drainage piDework.
Accordingly there is a need for a means of draining the water from areas such as shower trays which does not require any part of the draining means to be below floor level.
According to a first aspect of the present invention there is provided a method of removing water from a shower area comprising: a) providing i) a shower tray without a conventional drainage hole, and ii) a suction pipe; b) arranging one end of the suction pipe to extend generally downward towards the base of the shower tray; c) providing a clearance between this first end of the suction pipe and the base of the shower tray; and d) providing means at the second end of the suction pipe for sucking up water at the first end of the pipe.
According to a further aspect of the present invention there is provided an apparatus for use in removing water from a shower tray, the apparatus comprising an elbow joint positionable above the base of a shower tray to provide a clearance between the base and an end of the elbow, the apparatus further comprising means for producing suction at the end of the elbow adjacent the base of the shower.
The apparatus of the present invention may be provided in the form of a kit for use in adapting a conventional shower tray for use in the method of the present invention. For example, the kit may comprise an elbow joint and a pump.
In a further embodiment of the present invention there is provided a shower tray having a recessed portion in place of a conventional drainage hole, and a suction pipe having a first, suction end extending towards the base of the shower tray, wherein a clearance is provided between the suction end of the pipe and the base of the shower tray.
Typically the absence of a conventional drainage hole may be provided by manufacturing the shower tray without such a hole, or by plugging and sealing such a hole already provided.
Preferably a recess is provided in the base of the shower tray in place of the drainage hole to provide an area for accumulation of the water.
Preferably the clearance between the suction pipe and the base of the shower tray or recess provided therein is-not greater than 3 mm.
Preferably the suction pipe and recess where provided is provided towards one corner of the shower tray.
Preferably the means for applying suction to the suction pipe comprises an electric pump remote from the shower tray.
Optionally, the water is caused to pass through at least one filter before passing through the means for applying suction.
An annular filter may be placed around the suction end of the suction pipe. An in-line filter may be provided between the suction end of the suction pipe and the suction providing means.
The above and other aspects of the present invention will now be illustrated by way of example only with reference to the accompanying drawings in which;
Fig. 1 is a perspective view of one embodiment of the apparatus of the present invention;
Fig. 2 illustrates a typical bathroom installation of an embodiment of the apparatus of the present invention; and
Fig. 3 illustrates a filter system, suitable for use with the apparatus of the present invention.
Referring to Figure 1, in one embodiment of the apparatus of the present invention a pipe 10 extends through a wall 11 of a shower tray (a tray being shown generally at 12). Pipe 10 extends generally downwards towards the base 13 of the shower tray 12, there being provided a clearance x between the lower end 14 of the pipe and base 13 of the shower tray.
Pipe 10 as shown is provided with an elbow portion 15 in order to facilitate the downward projection towards the base 13. A seal 16 is provided in the wall 11 of the tray through which pipe 10 passes, the seal providing a watertight seal between the pipe and the wall of the shower tray.
Level access trays such as that illustrated are conventionally provided with an inclined base providing a slope to direct water towards a drainage hole provided in one corner. Accordingly, the apparatus of the present invention is, as shown, preferably provided in that corner of the shower tray towards where the water is directed.
Figure 2 illustrates further apparatus suitable for use in implementing the present invention. The apparatus comprises a pump 20, preferably of the self-priming type and preferably also having a run-dry facility allowing the pump to be left on without the motor burning out should the flow of water cease. An in-line filter 21 may be provided to prevent solid matter falling on to the shower tray from damaging the pump 20. Preferably the system is provided with an anti syphon device such as a multiple non-return valve to allow for plumbing of the system into a soil pipe without the need for a conventional p-trap. In addition to the inline filter, an annular filter comprising a wire mesh basket filter 30 may be provided around end 14 of pipe 10. A cover 31 may also be provided to further enhance the aesthetic qualities of the installation.
The shower tray may also be provided with conventional nonslip pads 32.
When the shower tray is to be used with a pump and an electric shower it is advantageous to provide much of the electrical supply apparatus for the pump integrated within the body of the electric shower unit. In particular, the transformer of the pump may be so integrated.
In a preferred embodiment the apparatus is provided with means for sensing the flow of water and operating the pump only in response thereto. Preferably, however, the pump continues to operate for a short period, for example 15 seconds, after the water flow has ceased.
Typically pipe 10 is of conventional 15mm copper, stainless steel or plastics material. By allowing for the use of conventional small diameter pipework (for example 15mm), the pipes can be easily hidden from view. Alternatively, as such size pipes are known from domestic central heating systems and are thus aesthetically acceptable in the home, it will not be essential to disguise the pipework other than by painting if appropriate. Larger pipework, in addition to beinq more unsightly may. depending upon the pump, cause the suction of too great a quantity of air when first starting the pump motor. This may result in a long delay before the motor can prime itself.
