Description

Technical Field

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

[0002] Controllers for use in wet environments, such as bathing facilities, are known to include an input movable between positions to affect control of a fluid delivery system. For example, shower controllers are known to include an input movable between positions to control a valve to permit or prevent water flow to a fluid delivery device, such as a shower head.

[0003] After moving an input of a controller for use in a wet environment from a first position to a second position, it may be desirable for the input to automatically return to the first position. It may also be desirable for a controller for use in a wet environment to include a sealed interior volume, such as for housing parts of the controller that are not suitable for getting wet. Summary of the Invention

[0004] According to a first aspect, a controller for use in a wet environment, such as a bathing area, is provided. The controller includes a base member, an input member, a seal extending between the input member and the base member, and a sealed interior volume at least partially defined by the base member, the input member, and the seal. The input member is movable relative to the base member between a neutral position and a control position. The seal is configured to bias the input member toward the neutral position.

[0005] This first aspect provides a controller for use in wet environments, comprising a single component (a seal) that provides two functions: automatically returning the input member to a neutral position after it has been moved to a control position; and providing a sealed internal volume. This advantageously reduces the overall number of components required to provide the controller by eliminating the need for separate seals and biasing devices. This in turn reduces manufacturing complexity and cost.

[0006] The input member is movable in a linear direction relative to the base member. The seal may be configured to bias the input member in a linear direction toward a neutral position. The controller may include a button.

[0007] The controller may include a pivot joint configured to allow the input member to pivot from a neutral position to a control position relative to the base member. The pivot joint may be configured to allow the input member to pivot from a neutral position to a plurality of control positions relative to the base member. The pivot joint may be configured to allow the input member to pivot from a neutral position to two, three, or four control positions relative to the base member. Up to ten control positions may be provided. The pivot joint thus enables a single input member to be used to provide multiple control functions. The controller may therefore include a rocker switch, such as a two-way rocker switch, a three-way rocker switch, or a four-way rocker switch.

[0008] In embodiments where the controller includes multiple control positions, the control positions can be equally spaced from one another. For example, the input member can include a circular cross-section when viewed in plan, and the control positions can be equally spaced about the circumference of a nominal circle arranged concentrically with the circular cross-section. In another example, the input member can include a square cross-section when viewed in plan, and the input member can be pivotable to a control position aligned with each corner of a nominal square arranged concentrically with the square cross-section.

[0009] The pivot joint can be configured to allow the input member to pivot relative to the base member about more than one axis. For example, the input member can be pivotable about two, three, or four different axes. The pivot joint can be configured to allow the input member to pivot relative to the base member about one or more axes in a single direction, or about one or more axes in opposite directions. Thus, a single axis can be provided for one or two control positions. For example, three axes can be provided for three control positions, wherein the input member is pivotable in a single direction about each axis. Alternatively, three axes can be provided for six control positions, wherein the input member is pivotable in opposite directions about each axis. The pivot joint can be configured to allow the input member to pivot relative to the base member in any direction, such as about any axis.

[0010] In embodiments where the pivot joint is configured to allow the input member to pivot relative to the base member about more than one axis, the axes may intersect at a point aligned with the center of the input member. Because the torque required to pivot the input member to each of the control positions is substantially equal, this may allow the input member to be moved to each of the control positions using substantially equal input forces. Alternatively, the axes may intersect at a point offset from the center of the input member. This may vary the input force required to move the input member to one or more of the control positions, as may be desired.

[0011] The controller may include an actuation point or points. At least one of the actuation point or points may be located at least partially within the sealed interior volume. At least one of the actuation point or points may be configured to be actuated by moving an input member to a control position or one of the control positions.

[0012] The actuation point or at least one of the actuation points is mechanically coupled to a mechanical control portion. The mechanical control portion may include any suitable arrangement of mechanical components, such as an arrangement of levers and linkages. The controller may include all or part of the mechanical control portion, or the mechanical control portion may be completely separate from the controller.

[0013] The controller may include an electronic switch. The actuation point or at least one of the actuation points may include electrical contacts of the electronic switch. The actuation point or at least one of the actuation points may include two electrical contacts of the electrical switch. The actuation point or at least one of the actuation points may include a first electrical contact of the electrical switch, and the input member may include a second electrical contact of the electrical switch. Moving the input member to the control position may cause the electrical contacts of the electrical switch to contact each other.

[0014] Locating the or at least one of the actuation points at least partially within the sealed interior volume may protect the or each actuation point from water damage in use.

[0015] The controller may include a first guide portion. The first guide portion may include a rib. The controller may include a second guide portion. The second guide portion may include a slot. The first guide portion may be fixed relative to one of the base member and the input member. The second guide portion may be fixed relative to the other of the base member and the input member. The rib may be received in the slot to inhibit lateral and / or rotational movement of the input member relative to the base member. The guide portion may help ensure that a force applied to the input member by a user causes the input member to move to a desired control position and mitigate any undesired movement of the input member.

[0016] The base member may include a guide portion. The input member may include a guide portion. One of the guide portion of the base member and the guide portion of the input member may include a rib. The other of the guide portion of the base member and the guide portion of the input member may include a slot. The rib may be received in the slot to inhibit lateral and / or rotational movement of the input member relative to the base member. The guide portions may be formed integrally with the base member and the input member, respectively. Alternatively, one or both of the guide portions may be formed separately and attached to the corresponding base member and / or input member. The guide portions confer the same advantages as discussed in the preceding paragraphs. Forming the guide portions integrally with the base member and the input member advantageously reduces the number of parts required to construct the controller.

[0017] The seal of any of the above embodiments may extend continuously in a circumferential direction relative to the base member and the input member.The seal may comprise a single component or may be formed from a plurality of parts bonded together or otherwise suitably attached.

[0018] The seal of any of the above-described embodiments can include a C-shaped or S-shaped cross-section when the input member is in the neutral position. The force provided by the seal to bias the input member toward the neutral position can be at least partially a result of the cross-sectional shape of the seal. The C-shaped or S-shaped cross-section can help provide a strong and reliable biasing force.

[0019] The seal of any of the above embodiments may comprise an elastomeric material. The seal may comprise EPDM rubber or silicone. The force provided by the seal to bias the input member toward the neutral position may be at least partially a result of the material properties of the seal.

[0020] The material properties and / or cross-sectional shape of the seal alone may be sufficient to provide the total biasing force required to return the input member to the neutral position from the control position or any one of the plurality of control positions.

[0021] In some embodiments, the seal may comprise a first flexible, non-elastic material and a second elastic material. For example, the seal may comprise a flexible rubber with an elastic metal insert.

[0022] In some embodiments, the seal may include additional means to bias the input member toward the neutral position. For example, the seal may include a magnetic material configured to provide opposing magnetic forces.

[0023] The controller of any of the above embodiments may include a spring configured to further bias the input member toward the neutral position. The spring may help ensure that the input member returns to the neutral position from the control position or any of the multiple control positions. In embodiments including a pivot joint, the spring may include a wave spring arranged coaxially with the pivot point of the pivot joint. In some embodiments, the spring may include a compression spring. In embodiments including a pivot joint and a compression spring, the longitudinal axis of the compression spring may be offset from the pivot point of the pivot joint. In some embodiments, the controller may include more than one spring.

[0024] The controller of any of the above embodiments can include a housing. The base member can be fixed relative to the housing and the input member can be movable relative to the housing. The housing can include an opening providing access to the input member. The housing can provide a means for mounting the controller at a point of use, such as a means for attaching the controller to a mounting surface such as a wall.

[0025] According to another aspect, a fluid delivery system is provided. The fluid delivery system comprises a fluid delivery device according to the present disclosure and a controller. The controller is operable to control one or more properties of a fluid delivered by the fluid delivery device during use.

[0026] The one or more characteristics of the fluid may include fluid flow and / or temperature.

[0027] The fluid delivery system may include a valve operable to control the flow of fluid to the fluid delivery device. The controller may be operable to control the valve. In embodiments where the controller includes an actuation point or points, at least one of the actuation point or points may be operably connected to the valve.

[0028] The fluid delivery system may include a plurality of fluid delivery devices.

[0029] The controller may be configured to permit a user to select any combination of one or more of the fluid delivery devices.

[0030] The fluid delivery device(s) may include a sprayer, such as a shower head or faucet.

[0031] The fluid may be water.

[0032] The fluid delivery system may be coupled to a fluid supply, such as a plumbing system that provides cold and / or hot water.

[0033] Unless mutually exclusive, any one of the features of the first aspect may be utilized mutatis mutandis in the second and other aspects. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Figure 1a and Figure 1b A schematic cross-sectional side view of a controller 10 for use in a wet environment, such as a bathing area, according to an embodiment is shown. The controller 10 includes a base member 1, an input member 2, a seal 3 extending between the input member 2 and the base member 1, and a sealed interior volume 4 defined by the base member 1, the input member 2, and the seal 3. The input member 2 is movable relative to the base member 1 between a neutral position and a control position. The seal 3 is configured to bias the input member 2 toward the neutral position.

[0044] Figure 1aThe input member 2 is shown in a neutral position, Figure 1b The input member 2 is shown in the control position. Figure 1a and Figure 1b In the example shown in FIG, input member 2 is moved from the neutral position toward the control position by applying a force to input member 2 in a direction toward base member 1. As input member 2 moves from the neutral position to the control position, seal 3 is compressed. After the force is removed from input member 2, seal 3 provides a restoring force that returns input member 2 to the neutral position.

[0045] The controller 10 may include one or more components housed within the sealed interior volume 4. For example, the controller 10 may include one or more electronic, electrical, optical, magnetic, or mechanical components housed within the sealed interior volume 4. The controller 10 may be configured to generate a control signal when the input member 2 moves to the control position. The controller 10 may include any suitable device for generating the control signal. For example, the controller 10 may include one or more sensors configured to detect when the input member 2 has moved to the control position. In some examples, the seal 3 may be configured to function as a resistor, wherein compression of the seal 3 when the input member 2 moves to the control position causes a change in resistance in the circuit. The control signal may be generated by the controller 10 based on the change in resistance.

[0046] In some embodiments, the controller 10 may include a pressure sensor configured to detect pressure changes within the sealed interior volume 4. Movement of the input member 2 relative to the base member 1 may affect pressure changes within the sealed interior volume 4. The controller 10 may be configured to generate a control signal dependent on the pressure changes detected by the pressure sensor.

[0047] In some embodiments, the controller 10 may include a proximity sensor, such as an infrared sensor or other suitable optical sensor, configured to detect when the input member 1 is in the control position. The controller 10 may be configured to generate a control signal dependent on the proximity sensor detecting that the input member 1 is in the control position.

[0048] Figure 2a and Figure 2b FIG2 shows a schematic cross-sectional side view of a controller 20 for use in a wet environment such as a bathing place according to an embodiment. Figure 1a and Figure 1b The controllers 10 of FIG. 1 and FIG. 2 have common features. Like reference numerals will be used to refer to like features.

[0049] Apart from Figure 1a and Figure 1b Features of the controller 10, Figure 2a and Figure 2bThe controller 20 further comprises an actuation point 5 located within the sealed volume 4. The actuation point 5 is configured to be actuated by moving the input member 2 to a control position. Figure 2a The input member 2 is shown in a neutral position, Figure 2b The input member 2 is shown in a control position. The seal 3 is configured to bias the input member 2 towards a neutral position.

[0050] Figure 3a 、 Figure 3b and Figure 3c FIG2 shows a schematic cross-sectional side view of a controller 30 for use in a wet environment such as a bathing place according to an embodiment. Figure 2a and Figure 2b The controller 20 has common features. Like reference numerals will be used to refer to like features.

[0051] Apart from Figure 2a and Figure 2b Features of the controller 20, Figure 3a 、 Figure 3b and Figure 3c The controller 30 also includes a pivot joint 6 configured to allow the input member 2 to pivot relative to the base member 1 from a neutral position to a control position. Figure 3a The input member 2 is shown in a neutral position, Figure 3b The input member 2 is shown in a first control position, Figure 3c The input member 2 is shown in a second control position. The seal 3 is configured to bias the input member 2 toward the neutral position. The controller 30 further includes two actuation points 5a, 5b located within the sealed volume 4. Each of the actuation points 5a, 5b is configured to be actuated by pivoting the input member 2 to one of the two control positions.

[0052] In some embodiments, the pivot joint 6 can be configured to allow the input member 2 to pivot relative to the base member 1 about one or more axes. The axes intersect at points aligned with or offset from the center of the input member 2. The axes can be perpendicular or at obtuse angles to each other. In some embodiments, the pivot joint 6 can be configured to allow the input member 2 to pivot from a neutral position to two or more control positions, such as three or four control positions, relative to the base member 1. In such an embodiment, the controller 30 can include two or more actuation points 5 located within the sealed volume 4, such as three or four actuation points 5. Each of the two or more actuation points 5 can be configured to be actuated by pivoting the input member 2 to one of the two or more control positions.

[0053] In other embodiments, the single actuation point 5 is located within the sealed volume 4. In such embodiments, the pivot joint 6 can be configured to allow the input member 2 to pivot relative to the base member 1 from a neutral position to a single control position, and the single actuation point 5 can be configured to be actuated by moving the input member 2 to the single control position.

[0054] In some embodiments, the sealed internal volume 4 of the controller 30 can be divided into multiple sealed chambers. An actuation point can be arranged in each sealed chamber. For example, when the input member 2 is configured to pivot from a neutral position to two control positions relative to the base member 1, the sealed internal volume 4 can be divided into two sealed chambers. In another example, when the input member 2 is configured to pivot from a neutral position to four control positions relative to the base member 1, the sealed internal volume 4 can be divided into four sealed chambers. The controller 20 may include a pressure sensor or multiple pressure sensors, and the pressure sensor is configured to detect pressure changes in each of the sealed chambers. When the controller 20 includes a single pressure sensor, the pressure sensor can be configured to detect pressure changes in each of the sealed chambers. When the controller 20 includes multiple pressure sensors, each of the pressure sensors can be configured to detect pressure changes in a different one of the sealed chambers. The controller 20 can be configured to generate different control signals depending on the sealed chamber in which the pressure change is detected.

[0055] In some embodiments, the controller 20 may include one or more proximity sensors, such as infrared sensors or other suitable optical sensors, configured to detect when the input member 1 has moved to one of the control positions. For example, where the input member 2 is configured to pivot from a neutral position to two control positions relative to the base member 1, the controller 20 may include two proximity sensors. In another example, where the input member 2 is configured to pivot from a neutral position to four control positions relative to the base member 1, the controller 20 may include four proximity sensors. Each of the proximity sensors may be configured to detect when the input member 2 has moved to a different one of the control positions. The controller 20 may be configured to generate a different control signal depending on the control position to which the input member 2 has moved.

[0056] One or more of the actuation points 5 of any of the controllers 10, 20, or 30 can be coupled to a mechanical control. Actuation of one or more of the actuation points 5 can cause the mechanical control to actuate. In use, the mechanical control(s) can be operable to adjust the operation of at least one fluid delivery device, such as a faucet or shower. For example, the mechanical control(s) can be operable to control the operation of a mechanical valve.

[0057] In some embodiments, any of controllers 10, 20, or 30 may include an electrical switch, and one or more of the actuation points 5 of any of controllers 10, 20, or 30 may include electrical contacts of the electrical switch. For example, the actuation point 5 may include two electrical contacts of the electrical switch that are offset from one another. To actuate the actuation point 5, the input member 2 may be moved to a control position to overcome the biasing force between the electrical contacts, for example, by contact between the input member 2 and one or both of the electrical contacts, thereby causing the electrical contacts to contact one another. In some examples, the actuation point 5 may include a single contact of the electrical switch, and the input member 2 may include another contact of the electrical switch. To actuate the actuation point 5, the input member 2 may be moved to a control position to cause the electrical contacts to contact one another. In use, the electrical switch may be electrically connected to an electronic valve, such as a solenoid valve. Contact between the electrical contacts of the electrical switch may close an electrical circuit that actuates the electronic valve. In use, the electrical switch may be operable to adjust the operation of at least one fluid delivery device, such as a faucet or shower.

[0058] Figure 4 A schematic cross-sectional isometric view of a controller 40 for use in a wet environment such as a bathing area according to an embodiment is shown. Figure 3a 、 Figure 3b and Figure 3c The controller 30 has common features. Like reference numerals will be used to refer to like features.

[0059] The base member 1 of the controller 40 includes a circumferential groove 101 for accommodating a fixing plate. In use, the fixing plate can be used to attach the controller 40 to a surface in a bathing place, such as a wall. The base member 1 also includes a plurality of bosses 102 for accommodating fasteners such as screws, which are used to fasten the controller 40 to the surface via the fixing plate. In some embodiments, the controller 40 can be attached to the surface using a device other than a fixing plate. In such embodiments, the groove 101 and the boss 102 may not be present. The base member 1 also includes a cable boss 103 for accommodating the terminal end of an electrical cable. The cable can provide power to the controller and / or can transmit control signals from the controller to parts of the fluid delivery system in use.

[0060] The pivot joint 6 of the controller 40 may be configured to allow the input member 2 to pivot relative to the base member 1 from a neutral position to four control positions. Figure 4 The input member 2 is shown in a neutral position. The controller 40 further comprises four actuation points located within the sealed volume 4. Two of the actuation points 5a, 5b are located in Figure 4. Each of the actuation points 5 is configured to be actuated by moving the input member 2 to one of the control positions. In other embodiments, the pivot joint 6 can be configured to allow the input member 2 to pivot from the neutral position to more or less than four control positions relative to the base member 1, such as six control positions or three control positions. In such embodiments, the controller 40 can include more or less than four actuation points 5, such as six actuation points or three actuation points. Each of the actuation points 5 can be configured to be actuated by pivoting the input member 2 to one of the control positions.

[0061] The controller 40 includes a first guide portion 7. Figure 4 As shown, a gap is provided between the first guide portion 7 and the base member 1 for accommodating electronic components of the controller 40, such as a printed circuit board. The first guide portion 7 includes four ribs 71a-d. Two of the ribs 71a and 71b are located at the bottom of the first guide portion 7. Figure 4 Shown in cross section. Figure 4 In the embodiment of the present invention, the first guide portion 7 is formed separately from the input member 2 and is fixed relative to the input member 2. In other embodiments, the input member 2 and the first guide portion 7 can be formed integrally. The controller 40 further includes a second guide portion 8. The second guide portion 8 includes four slots 81a-d. Two of the slots 81a, 81b are in Figure 4 Shown in cross section. Figure 4 In the embodiment of FIG, the second guide portion 8 is formed separately from the base member 1 and is fixed relative to the base member 1. In other embodiments, the base member 1 and the second guide portion 8 can be formed integrally. Each of the ribs 71a-d can be received in one of the slots 81a-d to inhibit lateral and / or rotational movement of the input member 2 relative to the base member 1.

[0062] In some embodiments, the first guide portion 7 includes one or more slots and the second guide portion 8 includes one or more ribs. In some embodiments, the first guide portion 7 may include more or fewer than four ribs 71, and the second guide portion 8 may include more or fewer than four slots 81. At least one of the ribs may be received in one of the slots to inhibit lateral and / or rotational movement of the input member 2 relative to the base member 1.

[0063] exist Figure 4 In the embodiment of FIG. 4 , the controller 40 includes four electrical switches. Each of the actuation points 5 a - d includes two electrical contacts of one of the electrical switches. The electrical contacts of each of the electrical switches are biased away from each other. The second guide portion 8 includes four contact portions 82 a - d. Two of the contact portions 82 a, 82 b are located at Figure 4is shown in cross-section. To actuate one of the actuation points 5a-d, the input member 2 is moved to one of the control positions, causing one of the contact portions 82a-d to apply a force to one or both of the electrical contacts of one of the electrical switches. The force applied by the contact portion 82 to the electrical contacts overcomes the biasing force between the electrical contacts. This causes the electrical contacts to come into contact with each other. In other embodiments, each of the actuation points 5a-d can comprise a first electrical contact of one of the electrical switches, and each of the contact portions 82a-d can comprise a second electrical contact of one of the electrical switches. To actuate one of the actuation points 5a-d, the input member 2 is moved to one of the control positions, causing the first electrical contact of one of the electrical switches to come into contact with the second electrical contact of the electrical switch. In use, each electrical switch can be electrically connected to an electronic valve, such as a solenoid valve. Contact between the electrical contacts of one of the electrical switches can close an electrical circuit that can actuate the electronic valve. In use, the electrical switch can be operable to adjust the operation of at least one fluid delivery device, such as a faucet or shower.

[0064] Figure 5a A schematic isometric view of the first guide portion 7 of the controller 40 is shown. Figure 5b A schematic isometric view of the second guide portion 8 of the controller 40 is shown. Each of the four ribs 71a-d is Figure 5a and each of the four slots 81a-d is in Figure 5b As shown in FIG. Two of the contact portions 82a, 82d are Figure 5b The other two contact portions 82b, 82c are not visible, but their positions are shown in FIG. Figure 5b It is easy to see.

[0065] The pivot joint 6 of the controller 40 can be configured to allow the input member 2 to pivot relative to the base member 1 about two axes. The first of the two axes extends along the longitudinal axis of a first slot 82a of the four slots 82a-d, passes through the pivot point of the pivot joint 6, and extends along the longitudinal axis of a second slot 82b of the four slots 82a-d. The pivot point of the pivot joint 6 is aligned with the center of the input member 2. The second of the two axes extends along the longitudinal axis of a third slot 82c of the four slots 82a-d, passes through the pivot point of the pivot joint 6, and extends along the longitudinal axis of a fourth slot 82d of the four slots 82a-d. The two axes extend parallel to each other. Because both axes pass through the pivot point of the pivot joint 6, and the pivot point of the pivot joint 6 is aligned with the center of the input member 2, the axes intersect at a point aligned with the center of the input member 2. This provides a "north, south, east, west" configuration of control positions. In other embodiments, the axes may be at obtuse angles to each other.

[0066] The controller 40 further includes a spring 9 configured to further bias the input member 2 toward the neutral position. In addition to the seal 3, the spring 9 provides an additional restoring force to return the input member 2 toward the neutral position after the input member 2 has moved toward one of the control positions. Figure 4 In the embodiment of FIG, spring 9 comprises a wave spring arranged coaxially with the pivot point of pivot joint 6. In some embodiments, a different type of spring may be provided, such as a compression spring arranged between base member 1 and input member 2. In some embodiments, more than one spring may be provided.
