Description

Technical Field

[0001] The present disclosure relates to a controller for use in a wet environment such as a bathing scene. The present disclosure also relates to a fluid delivery system, in particular a pipe or bathing system, comprising such a controller. Background Art

[0002] Controllers for use in bathing scenarios include, for example, digital shower controllers. Digital shower controllers typically include a manually operated mechanical input portion and an electronic component configured to output a control signal based on the movement or position of the mechanical input portion. The electronic components can be located in a sealed environment to protect these components from water during use. In use, the controller can be used to control one or more characteristics of the water ejected from the shower according to the control signal. For example, the controller can be used to control the actuation of an electronic valve (e.g., a solenoid valve) according to the control signal. The electronic valve can in turn control the mixing of the hot water supply and the cold water supply to control the temperature of the water delivered by a fluid delivery device (e.g., a shower head). Summary of the invention

[0003] A first aspect provides a controller for use in a humid environment, the controller comprising:

[0004] A manually operable input device connected to the base housing, the manually operable input device comprising:

[0005] a first manual input means; and

[0006] a second manual input member, wherein the second manual input member is movable relative to the first manual input member; and

[0008] Wherein, the first manual input member and the second manual input member are at least partially arranged outside the sealed environment.

[0009] The first manual input member and / or the second manual input member may be disposed substantially completely outside of the sealed environment.

[0010] The second manual input member is movable relative to the first manual input member, for example, rotatable relative to the first manual input member. When the second manual input member moves (eg, rotates) relative to the first manual input member, the first manual input member cannot move (eg, rotate).

[0011] The manually operable input device may include one or more additional manual input members. For example, the manually operable input device may include a third manual input member, and optionally a fourth manual input member, and further optionally a fifth manual input member, and further optionally a sixth manual input member, etc.

Alternatively, the arc may be continuous, i.e., the manual input member may be rotatable around the axis without any restrictions. The one or more manual input members movable along an arc around the axis may include a rotary dial, a seat, a lever or a handle.

[0013] One or more of the manual input members may be slidable, for example slidable within a slot or groove. The slidable manual input member may comprise a lever or a handle.

[0014] One or more of the manual input members may include a touch screen or a keyboard. The touch screen or the keyboard may be configured so that the touch screen or the keyboard does not rotate.

[0025] In embodiments comprising a button, the diaphragm seal may be arranged to be compressed by actuation of the input portion.

[0026] In example embodiments, there may be no seal between the input portion of the button and the rotary dial or bezel.

[0027] The rotating dial or seat may be configured so that the rotating dial or seat can rotate freely. The rotating dial or seat may be configured to rotate between two predetermined limits. The rotating dial or seat may be configured to rotate incrementally. The rotating dial or seat may be configured to rotate about a single axis of rotation that passes through or is close to a center point of a manual input member disposed within the periphery of the rotating dial or seat. The manual input member disposed within the periphery of the rotating dial or seat may include a button, a touch screen, and / or a keyboard.

[0028] The controller may include a non-contact position sensing system including a first portion disposed on or in one or more of the manual input members and a second portion disposed within a sealed environment, wherein user-initiated movement of the manual input member results in movement of the first portion relative to the second portion. The first portion or the second portion may be configured to detect movement of the other of the first portion and the second portion and output a signal based on user-initiated movement of the first portion relative to the second portion. The non-contact position sensing system may be configured such that: in use, the first portion and the second portion are never located in the same plane and are never radially offset from each other relative to an axis extending vertically from the base housing and passing through the manually operable input device.

[0036] The magnet holder may be pivotable, slidable or rotatable relative to the button. The magnet holder may be continuously rotatable relative to the button. The magnet holder may be rotatable relative to the button within a fixed angle range.

[0037] In order to be suitable for use in a humid environment, it is generally necessary to protect the magnet so as to inhibit corrosion. For example, the magnet can be protected by means such as a coating of a polymer (e.g., a resin) or electroplating containing a metal (e.g., nickel). The need for such a treatment may make the magnet relatively more expensive than the sensor. In some example embodiments, the controller may include a magnetic sensing system that includes fewer magnets than the sensor. Therefore, the manufacturing cost of the controller may be relatively reduced. Another benefit may be that relatively less magnetic material may be required, which may help limit manufacturing costs and / or minimize possible supply problems.
