Definitions

  • This disclosure relates to a controller for use in a wet environment such as an ablutionary setting.
  • the disclosure also relates to a fluid delivery system, in particular a plumbing or ablutionary system comprising such a controller, and a method of manufacturing a controller.
  • Controllers for use in ablutionary settings include, for example, digital shower controllers.

  • the electronic switch forms part of a control circuit which is typically used to control one or more characteristics of the water sprayed from the shower.
  • the electronic switch may form part of a control circuit used to control actuation of an electronic valve, e.g. a solenoid valve.
  • the electronic valve in turn may control the supply of water to a showerhead in response to actuation of the electronic switch.
  • a digital shower controller with an electronic display for indicating to a user various functions being performed by the controller.
  • the display may indicate a target water temperature which the controller will deliver through control of the electronic valve.
  • Such displays typically reflect light when inactive, meaning that dirt located on the surface of the display is visible.
  • the edges of the display may be visible relative to the surrounding housing of the controller.
  • a controller for use in a wet environment such as an ablutionary setting.
  • the controller comprises a display for displaying information related to the operation of a fluid delivery system.
  • the display comprises a light source and a semi-transparent layer.
  • the light source and the semi-transparent layer are configured such that the semi-transparent layer absorbs or reflects light transmitted towards the light source and allows light transmitted from the light source to be transmitted from the display, such that the light source appears hidden when information is not displayed by the light source.
  • the display may comprise an input member of a control member to provide an input to the controller.
  • a controller for use in a wet environment such as an ablutionary setting.
  • the controller comprises a display for displaying information related to the operation of a fluid delivery system.
  • the display comprises an input member of a control member to provide an input to the controller.
  • the display may comprise a light source and a semi-transparent layer.
  • the light source and the semi-transparent layer may be configured such that the semi transparent layer absorbs or reflects light transmitted towards the light source and allows light transmitted from the light source to be transmitted from the display, such that the light source appears hidden when information is not displayed by the light source.
  • the semi-transparent layer may have an opacity selected such that ambient lighting is reflected or absorbed by the semi-transparent layer and light emitted by the light source is transmitted through the semi-transparent layer.
  • the light source may be configured to transmit light having an intensity measured at the semi-transparent layer greater than an intensity of ambient lighting measured at the semi-transparent layer.
  • Ambient lighting herein refers, for example, to light produced by a typical domestic ambient light source, such as an LED, CFL or halogen light bulb, within a typical domestic setting, such as an ablutionary setting (a bathroom for example).
  • a typical domestic ambient light source such as an LED, CFL or halogen light bulb
  • Such typical domestic light sources may emit light with an output in the range of 4-130 Watts.
  • the distance between the semi-transparent layer of the display and an ambient light source may be greater than 1 metre, greater than 2 metres, or greater than 5 metres, for example.
  • the intensity of ambient indoor lighting measured at the semi-transparent layer typically may be in the range of 0.001-15 Wm 2 (Watts per metres squared), for example.
  • a maximum distance between the light source and the semi-transparent layer may be selected such that light emitted by the light source, in use, is transmitted through the semi-transparent layer.
  • a maximum distance between the light source and the semi transparent layer may be less than 10 mm, less than 5 mm, less than 4 mm, less than 3 mm, less than 2 mm, or less than 1 mm, for example.

  • the output of light transmitted by the light source may be in the range of 4-24 W, for example.
  • the intensity of light transmitted by the light source measured at the semi transparent layer may be at least 3 kWm 2 -and/or up to 2 MWm 2 , for example. Therefore, due to the relative distances of the ambient light source and the light source of the display from the semi-transparent layer, the intensity of light from the light source of the display measured at the semi-transparent layer may be orders of magnitude greater than the intensity of light from the ambient light source measured at the semi-transparent layer.
  • the edges or outline of the light source or any part thereof will not be visible under ambient lighting conditions.
  • the light source appearing hidden when information is not displayed i.e. when the light source is not turned on

  • the semi-transparent layer may cover a major portion of the light source.
  • the semi transparent layer may cover substantially all of the light source.
  • the display may be configured to provide one or more inputs to the controller. This dual functionality of the display, i.e. displaying information and providing one or more inputs to the controller, may remove the requirement for additional components.

  • the control member may comprise an electrical switch or a mechanical control member.
  • the controller may comprise a housing.
  • the controller may further comprise a resilient biaser.
  • the input member may be moveable with respect to the housing and the input member may be biased towards a neutral position by the resilient biaser. Providing a housing enables the controller to be easily installed as a single unit. Biasing the input member towards a neutral position enables easy operation of the input to the controller.
  • the housing may comprise a diaphragm, and the resilient biaser may comprise the diaphragm.
  • the diaphragm provides a flexible housing to enable ease of installation.
  • the resilient biaser comprising the diaphragm, for example forming the diaphragm from an elastic material, removes the requirement for a separate part to resiliently bias the input member towards the neutral position.
  • the input member may comprise a rocker. This enables the input member to be used to control a plurality of functions.
  • the controller may comprise a further input member.
  • the further input member may not comprise the display.
  • the further input member may comprise a bezel or a knob rotatable with respect to the display, or a lever or handle translatable with respect to the display.

  • the bezel being removable may mean that the bezel can be easily removed by a user without the need for the use of tools.
  • the bezel not being removable may mean that tools or other intervention outside of normal use of the controller may be required to remove the bezel.
  • the further input member may advantageously provide the controller with further functionality.

  • the controller may be battery powered or may be configured to be powered by mains electricity. Where the controller is battery powered, the controller may comprise one or more batteries that are rechargeable. The batteries may be rechargeable by connecting the controller to a mains power supply, for example by means of a USB interface. Any suitable battery may be employed, e.g. one or more lithium ion batteries.
  • the semi-transparent layer of any of the above described embodiments may be black or white.
  • a black semi-transparent layer may improve the legibility of information displayed by the light source, whereas a white semi-transparent layer may be better suited to environments in which the intensity of the ambient lighting is greater.
