Description

The present invention relates to improvements in or relating to shower apparatus.
Conventional shower apparatus, usually housed in a shower enclosure or above a bath, generally include a shower head attached to one end of a conduit means. The other end of the conduit means is in communication with a mixing means which, in turn, is attached to a hot and cold water supply. The mixing means enables the hot and cold water to be mixed so that the water passing through the shower head, via the conduit means, onto the user, is of a desired temperature previously selected by the user. The major disadvantage of such conventional shower apparatus is that the user, in order to direct the flow of water onto various parts of his/her body, either has to move in relation to the shower head, or alternatively, has to remove the shower head from its associated holder and move the shower head around his/her body, whilst holding same.
US-A-5121511 discloses a shower apparatus comprising a plurality of shower heads each attached to respective conduit means, each of the conduit means also being in communication with a mixing means which is in communication with a hot and cold water supply, wherein diverter means are located between the mixing means and each of the conduit means for diverting water originating from the mixing means either to one shower head at a time, or alternatively, to more than one shower head at the same time.
It is an object of the present invention to provide a shower apparatus which at least minimises the disadvantages outlined above. In particular, the present invention provides a shower apparatus comprising a plurality of shower heads whereby water can be directed either solely through one of said shower heads onto the user, or alternatively, through more than one shower head at the same time onto the user, thereby providing a very flexible shower environment and experience, permitting the user to easily and quickly move the direction of the water hitting them, rather than having to move in relation to the shower heads or hold a flexible shower head and move it around their body.
According to the present invention there is provided a shower apparatus comprising a plurality of shower heads each attached to respective conduit means, each of the conduit means also being in communication with a mixing means which is in communication with a hot and cold water supply, in that diverter means being located between the mixing means and each of the conduit means for diverting water originating from the mixing means either to one shower head at a time, or alternatively, to more than one shower head at the same time characterised in that the diverter means comprises a valve means in the form of a ceramic disc diverter valve means comprising a valve housing, a first static disc having a plurality of apertures provided therein, a second rotating disc having a single aperture therein, the number of apertures in the first static disc corresponding to the number of shower heads utilised, the location of the apertures in such discs being so arranged and/or the shape of the discs being so designed, that, when the rotating disc is rotated it is possible to divert water either to one of the shower heads at a time, or alternatively, to more than one shower head at the same time, and operating means for operating the diverter valve means.
In a preferred embodiment, said shower apparatus is preferably in the form of a shower column, which column is preferably provided with four shower heads. In such case, the diverter means can divert water to each of said shower heads separately, or to more than one, preferably two, shower heads at the same time.
Preferably, the shower apparatus includes drainage means to reduce the risk of limescale build up in the shower heads. In a preferred embodiment, the drainage means is in the form of a linked recess on the surface of the rotating disc which connects the conduits that are not in use at the time, thereby enabling water to drain from one shower head to another and hence, clear all water through the lowest open shower head.
One embodiment of a shower apparatus of the present invention which comprises four shower heads and diverter means for diverting water originating from the mixing means to one shower head, or to two shower heads at the same time, will now be described by way of example and with reference to the accompanying drawings, in which:
  • Fig. 1A is a side view of one embodiment of a shower apparatus of the present invention;
  • Fig.1B is a front view of the shower apparatus of Fig. 1A;
  • Fig.2 illustrates a ceramic disc diverter valve;
  • Figs.3A&B illustrate the water flow when the ceramic disc diverter valve is set to direct water to the upper shower head;
  • Figs.4A&B illustrate the water flow when the ceramic disc diverter valve is set to direct water to the hand shower head;
  • Figs. 5A&B illustrates the water flow when the ceramic disc diverter valve is set to direct water to the mid-body shower head;
  • Figs. 6A&B illustrates the water flow when the ceramic disc diverter valve is set to direct water to the foot shower head; and
  • Figs. 7A&B illustrates the water flow when the ceramic disc diverter valve is set to direct water to the upper shower head as well as the mid-body shower head.
    • With reference to Figs.1A&B, a shower apparatus 10 comprises four shower heads directable to different parts of the body, namely, an upper shower head 11 directable towards the head of the user (not illustrated), a hand shower head 12 directable towards the hands of the user, a mid-body shower head 13 directable towards the mid-body regions of the user and a lower shower head 14 directable towards the user's feet.
    The upper shower head 11 is attached to first conduit means 21, the hand shower head 12 is attached to second conduit means 22, the mid-body shower head 13 is attached to third conduit means 23 and the lower shower head 14 is attached to fourth conduit means 24. Said conduit means 21, 22, 23, 24 are all in communication with the diverter means 15, as illustrated in Fig. 2.
    The diverter means are in the form of a ceramic disc diverter valve 15. Said ceramic disc diverter valve comprises a disc carrier 40, a static disc 50, a rotating disc 60, a bush 63, washers 64, a front cover 70, an indenting disc 80, an indenting ball 81 all housed within the diverter body 30. When assembled, as illustrated in Fig. 2, a locking ring 82 secures said disc carrier 40, said static disc 50, said rotating disc 60, said bush 63, said washers 64, said front cover 70 within the diverter body 30. Said indenting disc 80 and said indenting ball 81 are retained by a circlip 84.
    The ceramic disc diverter valve 15 is in communication with the mixing means 17 via a fifth conduit means 74 attachable to the front cover 70. Since the mixing means 17 is of the conventional type, and is well known in the art, it shall not be described further herein.
    The diverter body 30 comprises apertures 31, 32, 33, 34, all in communication with the conduit means 21, 22, 23, 24, and a central aperture 35 extending therethrough. The disc carrier 40 comprises apertures 41, 42, 43, 44 and a central aperture 45 extending therethrough. The static disc 50 comprises apertures 51, 52, 53, 54 and a central aperture 55 extending therethrough. The rotating disc 60 comprises a central aperture 65 and an aperture 62 extending therethrough. When assembled, a spindle 83 passes through the central apertures 35, 45, 55, 65 and the spindle 83 is secured at one end of the diverter body 30 by a screw 19. When assembled, the apertures 31, 41, 51 and 32, 42, 52 and 33, 43, 53 and 34, 44, 54 are aligned.
    With reference to Figs. 3A&B, when the control dial 90 is set to the upper shower head 11 the aperture 62 on the rotating disc 60 is aligned with the apertures 31 located in the diverter body 30, the aperture 41 located in the disc carrier 40 and the aperture 51 located on the static disc 50. Consequently, water originating from the mixing means 17 passes down through the fifth conduit means 74 into the ceramic disc diverter valve 15 through the flow path formed by the aligned apertures 62, 51, 41, 31 up to the upper shower head 11 via conduit means 21 and onto the user.
    With reference to Figs. 4A&B, when the control dial 90 is set to the hand shower head 12 the aperture 62 on the rotating disc 60 is aligned with the apertures 32 located in the diverter body 30, the aperture 42 located in the disc carrier 40 and the aperture 52 located on the static disc 50. Consequently, water originating from the mixing means 17 passes down through the fifth conduit means 74 into the ceramic disc diverter valve 15 through the flow path formed by the aligned apertures 62, 52, 42, 32 up to the hand shower head 12 via conduit means 22 and onto the user.
    With reference to Figs. 5A&B, when the control dial 90 is set to the mid-body shower head 13 the aperture 62 on the rotating disc 60 is aligned with the apertures 33 located in the diverter body 30, the aperture 43 located in the disc carrier 40 and the aperture 53 located on the static disc 50. Consequently, water originating from the mixing means 17 passes down through the fifth conduit means 74 into the ceramic disc diverter valve 15 through the flow path formed by the aligned apertures 62, 53, 43, 33 up to the mid-body shower head 13 via conduit means 23 and onto the user.
    With reference to Figs. 6A&B, when the control dial 90 is set to the lower shower head 14 the aperture 62 on the rotating disc 60 is aligned with the apertures 34 located in the diverter body 30, the aperture 44 located in the disc carrier 40 and the aperture 54 located on the static disc 50. Consequently, water originating from the mixing means 17 passes down through the fifth conduit means 74 into the ceramic disc diverter valve 15 through the flow path formed by the aligned apertures 62, 54, 44, 34 up to the lower shower head 14 via conduit means 24 and onto the user.
    So that water originating from the mixing means 17 may be diverted to more than one shower head 11, 12, 13, or 14 at the same time, the apertures 51, 52, 53 and 53 on the static disc 50 may be so arranged so that aperture 62 on the rotating disc 60 can be partially aligned with any two of the apertures 51, 52, 53 or 54 which are adjacent to one another. For example, and with reference to Figs. 7A&B, when the control dial 90 is set to the upper shower head 11 and the mid-body shower head 13 the aperture 62 on the rotating disc 60 is partially aligned with the apertures 31 and 33 located in the diverter body 30, the apertures 41 and 43 located in the disc carrier 40 and the aperture 51 and 53 located on the static disc 50. Consequently, water originating from the mixing means 17 passes down through the fifth conduit means 74 into the ceramic disc diverter valve 15 through the flow path formed by the aligned apertures 62, 51, 53, 41, 43, 31,33 up to the upper shower head 11 and the mid-body shower head 13 via conduit means 21 and 23 respectively and onto the user.
    In order to simply change the direction of the water the user simply rotates the control dial 90 in any direction to the desired position.
    Although the present invention has been described by way of example to a shower apparatus comprising four shower heads and diverter means which is capable of diverting water to one shower head, or to two shower heads at the same time, by changing the orientation, size, shape or number of both the apertures on the static disc 50 and the rotating disc 60, it is possible to divert water originating from the mixing means 17 up to any selected number of shower heads separately or at the same time.
