DESCRIPTION:
BRIEF SUMMARY
This invention relates to multi-mode shower heads usually in the form of handsets and in which provision is included for effecting cleaning of fine outlet perforations which otherwise tend to become blocked or restricted with lime scale or other clogging matter.
Thus EP-A-0 284 801 (Grohe) discloses a multi mode shower head having a series of outlet cleaning pins which are cam operated for cleaning operation between each showering mode in an automatic manner so that each time there is a change of showering mode the pins are operated to effect outlet cleaning. Whereas an automatic cleaning action is obtained, excessive operation and wear of the pin mechanism may occur.
The object of the invention is to provide a multi-mode shower head or handset in which cleaning of fine outlet perforations can be readily effected as and when required. Practical advantages of the invention in this and other respects including constructional features will be apparent from the following description.
According to this invention a multi-mode shower head or handset in which a body member or cartridge is secured for relative angular movement to the head and has a valve like cooperation (at 12) with the hollow interior of the head for directing water flow from the head via passageways in the cartridge to arrangements of showering mode outlet openings including fine spray outlet openings at the front face of the cartridge, the showering modes from said outlets being selected by turning the cartridge to appropriate settings on the head, and a series of cleaning pins are rotatable with the cartridge and co-axially movable relative thereto for cleaning penetration into corresponding fine spray outlet openings and withdrawal therefrom; is characterised in this that the cleaning pins are operated for such co-axial movement by follower means to the series of cleaning pins which cooperates with a cam formation or track within the head, the cam co-action being such that the cleaning pins remain inoperative during any of the showering mode settings of the cartridge and are only independently operated by the cam formation or track by further turning movement of the cartridge beyond the showering mode settings.
Practical examples of shower handsets embodying the invention are shown in the accompanying drawings in which:
FIG. 1 is a side elevation of the handset of which the head portion is in section to reveal the internal mechanism shown in a shower mode;
FIG. 2 is a sectional view of the head portion on an enlarged scale with the mechanism shown in the cleaning condition;
FIGS. 3 to 6 are diagrammatic detail elevational views showing the inoperative and operative conditions of one of the cleaning pins;
FIG. 7 is a side elevation of a further form of the handset shown in a showering mode and in which the head portion is also shown in section to reveal the internal mechanism, and
FIGS. 8 to 12 are diagrammatic detail elevational views showing cam co-action of the mechanism of FIG. 7 in the showering modes and cleaning and intermediate positions.
Like parts are referred to by the same or similar reference numerals through the drawings.
In the example of the handset now described with reference to FIGS. 1 to 6 it provides three showering or spraying modes, namely a central pulsing emission, or an inner annular aerated or "champagne" emission, or an outer annular fine spray emission. The number, nature, arrangement and sequence of the modes may be varied according to requirements and the mechanism and its showering operation are of generally known form as follows:
Referring in particular to FIG. 2 water under pressure is admitted along the tubular neck or handle 11 of the handset 1 into the head portion 10 where it enters openings 12 in a partition 13 across the interior of the head portion 10. Accommodated between the partition 13 and a front face member or plate 3 is a body member or cartridge 2 which is angularly movable about the central axis X so as to have a valve like cooperation with the openings 12 in relation to passageways in the cart
