Bathing device or pipeline device

Abstract

A bathing device or piping device includes a valve assembly including a valve inlet, two or more valve outlets, and a switching element that allows fluid communication between the inlet and a first valve outlet and / or a second valve outlet. A fluid pressure acting on the switching element above or below a threshold value causes the inlet to be in fluid communication with the first valve outlet but not with the second valve outlet, or causes the inlet to be in fluid communication with the second valve outlet but not with the first valve outlet. A first set of fluid delivery outlets is in fluid communication with the first valve outlet and provides a first spray pattern. A second set of fluid delivery outlets is in fluid communication with the second valve outlet and provides a second spray mode.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority from UK patent application No. 2309434.5 filed on June 22, 2023, the entire disclosure of which is incorporated herein by reference. Technical Field

[0003] The present disclosure relates to a bathing device or a plumbing device. More specifically, the present disclosure relates to a bathing device including a shower head, which is used for plumbing fixtures or bathing installations such as showers or faucets. Background Art

[0004] As is well known, various types of shower heads are used in bathing systems. Typically, such shower heads are adapted to provide a variety of spray modes. Conventionally, switching the spray mode requires the user to manually (e.g., using a rod or button) actuate a valve mechanism. The disadvantage of this method is that the user needs to interact directly with the shower head.

[0005] As an alternative, some sprinkler heads use electronic controllers (including activated solenoids or motor shunts) to switch between spray modes. This approach also requires the user to interact directly with the sprinkler head, or use a remote electronic interface, which requires a wired connection to the controller or a wireless connection (such as Bluetooth) to the energy storage device. Wired or wireless connections increase the complexity and cost of installing and maintaining such sprinkler heads. Summary of the invention

[0038] Figure 1 A valve assembly 2 for use in a bathing device or a plumbing device is shown. The valve assembly 2 comprises a valve inlet 20, through which a fluid is supplied to a front chamber 25 when in use. As will be described in detail below, when in use, the fluid can flow from the front chamber 25 to a first valve outlet 21 and a second valve outlet 22.

[0039] The valve assembly 2 further includes an operable switching element 24 to selectively allow fluid communication between the valve inlet 20 and the second valve outlet 22. The switching element 24 can be actuated by the fluid pressure in the front chamber 25. In the present example, the switching element 24 includes a pressure relief valve 27. When the fluid pressure acting on the switching element 24 is lower than the threshold fluid pressure, the pressure relief valve 27 is closed and the switching element 24 is referred to as operating in the first mode. In the first mode, the pressure relief valve 27 prevents fluid communication between the front chamber 25 and the second valve outlet 22. In the first mode, the front chamber 25 and the valve inlet 20 are fluidically connected to the first valve outlet 21, and are not fluidically connected to the second valve outlet 22.

[0040] In contrast, when the fluid pressure acting on the switching element 24 reaches or exceeds the threshold fluid pressure, the pressure relief valve 27 opens and the switching element 24 is said to operate in the second mode. In the second mode, the front chamber 25 and the valve inlet 20 are fluidically connected to both the first valve outlet 21 and the second valve outlet 22.

[0041] In this way, the switching element 24 is actuated by fluid pressure and is configured to switch from operating in the first mode to operating in the second mode, and vice versa, due to changes in fluid pressure through a threshold fluid pressure. This pressure-induced switching can provide a compact alternative to expensive and complex digital control switching methods.

[0042] Switching between the first valve outlet 21 and the second valve outlet 22 can be actuated by both increasing and decreasing fluid pressure (via a threshold fluid pressure). This may be advantageous over conventional diverter valve assemblies, which may use fluid pressure to maintain a selected outlet but may not be operable to switch outlets when pressure increases. Such conventional valve assemblies typically require direct manual or digital actuation of the valve itself. In contrast, the reversible pressure-induced spray mode switching described in the present disclosure can provide a compact alternative to conventional switching methods that typically require a user to directly actuate the valve.

[0043] The valve assembly 2 further includes a flow regulator 26, which is located downstream of the outlet from the front chamber 25 and upstream of the first valve outlet 21. The flow regulator 26 is configured to limit the maximum flow rate output from the first valve outlet 21. The flow regulator may include a flow regulating geometry within the valve assembly 2, such as a flow restrictor having one or more orifices passing therethrough. When the flow rate from the valve inlet 20 exceeds the flow rate limit of the flow regulator 26, the fluid pressure within the front chamber 25 increases. If the increase in fluid pressure within the front chamber 25 is sufficient to cause the fluid pressure to reach or exceed the threshold fluid pressure, the pressure relief valve 27 opens, thereby switching the switching element 24 from the first mode to the second mode. In this way, the flow regulator 26 can be used to reduce the flow rate from the inlet 20, at which flow rate the switching element 24 begins to operate in the second mode.

[0044] The pressure relief valve 27 may be selected so that the pressure relief valve 27 has an opening pressure substantially equal to or greater than the fluid pressure in the front chamber 25 when the flow regulator is operating at its flow rate limit. Equivalently, the flow regulator may be selected to have a maximum flow rate limit so that the fluid pressure in the front chamber 25 is substantially equal to or greater than the opening pressure of the pressure relief valve 27 when the flow regulator is operating at its flow rate limit. By selecting the pressure relief valve 27 so that the pressure relief valve 27 has an opening pressure greater than the fluid pressure in the front chamber 25 when the flow regulator is operating at its flow rate limit, a buffer may be provided between switching from the first mode to the second mode, and vice versa. Thus, dripping from the second mode when the first mode is operating towards the upper limit of its flow rate may be prevented or at least reduced. There may be a cleaner cutoff when switching from the first mode to the second mode, and vice versa.

[0045] Figure 2 A bathing device 1 is shown, which includes a shower head 4 for showering, and includes Figure 1 Valve assembly 2 in. Figure 2 As shown, the showerhead 4 includes a device inlet 5 which is threaded so as to be coupled to a fluid supply pipe (not shown). The valve inlet 20 of the valve assembly 2 is in fluid communication with the device inlet 5 .

[0046] The shower head 4 includes a shower face 3, the shower face 3 includes a plurality of fluid delivery outlets 30, the fluid delivery outlets 30 include a first group of fluid delivery outlets 31 and a second group of fluid delivery outlets 32. In this example, the shower head 4 includes: a first chamber 41, which is configured to supply fluid to the first group of fluid delivery outlets 31; a second chamber 42, which is configured to supply fluid to the second group of fluid delivery outlets 32. In this example, the second chamber 42 is generally annular and is arranged to at least partially surround the first chamber 41. In the illustrated example, the first group of fluid delivery outlets 31 is located at the center of the shower face 3, and the second group of fluid delivery outlets 42 is arranged at the periphery of the shower face 3 so that the first group of fluid delivery outlets 31 is surrounded by the second group of fluid delivery outlets 32. In other embodiments, the first group of fluid delivery outlets and the second group of fluid delivery outlets can be configured in different ways relative to each other and / or relative to the shower face. The first group of fluid delivery outlets and the second group of fluid delivery outlets can be configured in any way relative to each other and / or relative to the shower face without departing from the scope of the present disclosure.

[0047] The device 1 is configured such that the first valve outlet 21 of the valve assembly 2 is in fluid communication with the first set of fluid delivery outlets 31 (via the first chamber 41). Likewise, the device 1 is configured such that the second valve outlet 22 is in fluid communication with the second set of fluid delivery outlets 32 (via the second chamber 42).

[0048] exist Figure 2 In the figure, the shower head is shown as a switching element 24 ( Figure 1 ) together with the first mode. In the first mode, the front chamber 25 and the valve inlet 20 are fluidically connected to the first valve outlet 21, and are not fluidically connected to the second valve outlet 22. Therefore, the fluid is only supplied to the first group of fluid delivery outlets 31, and the spray head 4 is said to be operated in the first spray mode. The fluid output from the plurality of fluid delivery outlets 30 is Figure 2 and Figure 3 The grey triangle 7 in FIG.

[0049] Figure 3 The switching element 24 of the valve assembly 2 is shown when it operates in the second mode. Figure 2 In the second mode, the action on the switching element 24 ( Figure 1) reaches or exceeds the threshold fluid pressure, the pressure relief valve 27 opens. The front chamber 25 and the valve inlet 20 are fluidically connected to the second valve outlet 22, and the second valve outlet 22 is sent to the second group of fluid delivery outlets 32, thereby generating a second spray mode. The front chamber 25 and the valve inlet 20 are also fluidically connected to the first valve outlet 21, and the first valve outlet 21 is sent to the first group of fluid delivery outlets 31, so that the spray head 4 can operate in the first spray mode and the second spray mode at the same time. This can advantageously provide greater coverage and a higher net flow rate from the fluid delivery outlet 30, which may be useful in certain cleaning applications (e.g., shampooing).

[0050] In this way, the device 1 is actuated by fluid pressure and is configured to switch from operating in the first spray mode to operating in the first spray mode to operating in the second spray mode, and vice versa, due to a change in fluid pressure through a threshold fluid pressure. This pressure-induced spray mode switching can provide a compact alternative to expensive and complex digital control switching methods.

[0051] In an alternative embodiment, the device 1 may be configured so that the first valve outlet 21 of the valve assembly 2 is in fluid communication with the second set of fluid delivery outlets 32 (through the first chamber 42). In this case, the device 1 may be configured so that the second valve outlet 22 is in fluid communication with the first set of fluid delivery outlets 31 (through the first chamber 41). Therefore, in the first spray mode, fluid may be supplied only to the second set of fluid delivery outlets 32 and the spray head 4. In this alternative embodiment, when the switching element 24 of the valve assembly 2 is operated in its second mode, the fluid pressure ( Figure 1 ) reaches or exceeds the threshold fluid pressure, the pressure relief valve 27 opens. The front chamber 25 and the valve inlet 20 are fluidly connected to the second valve outlet 22, which is sent to the first set of fluid delivery outlets 31, thereby producing a second spray mode. The front chamber 25 and the valve inlet 20 are also fluidly connected to the first valve outlet 21, which is sent to the second set of fluid delivery outlets 32, so that the spray head 4 can be operated in the first spray mode and the second spray mode at the same time. This can advantageously provide greater coverage and a higher net flow rate from the fluid delivery outlet 30, which may be useful in certain cleaning applications (e.g., shampooing).

[0052] The bathing device 1 may further include a controller (not shown) for changing the flow rate from the fluid supply to the at least one valve inlet 20. Changing the flow rate from the fluid supply can be used to change the action on the switching element 24 ( Figure 1) to switch the switching element 24 between different modes. Such a controller may be a digital controller configured to vary the flow rate from the fluid supply so that the switching element: switches from the first mode to the second mode when the user actuates the digital controller; and switches from the second mode to the first mode after a predetermined period of time (e.g., 30 seconds). Returning to the low flow rate mode after the predetermined period of time can improve water economy by providing the user with a high flow rate spray mode only for a limited period of time specific to the desired purpose (e.g., shampooing).

[0053] Alternatively, the controller may also include a non-digital manually actuated valve (eg, provided with a lever or rotatable dial for actuating the controller).

[0054] Figures 1 to 3 The bathing device 1 and valve assembly 2 shown in the should be taken as examples only. For example, it is obvious to the skilled person that the valve assembly 1 can be scaled up to include any number of additional valve outlets, each valve outlet being associated with an additional operating mode of the switching element (and an additional spray mode of the bathing device 1). Figure 4 An example of this is shown.

[0055] Figure 4 Another example of a bathing device 1a is shown. The bathing device 1a includes a shower head 4a for showering, and includes a valve assembly 2a.

[0056] like Figure 4 As shown, the showerhead 4a includes a device inlet 5a that is threaded to enable coupling to a water supply pipe (not shown). The valve assembly 2a includes a valve inlet 20a that is in fluid communication with the device inlet 5a.

[0057] In use, fluid is supplied to the front chamber 25a through the valve inlet 20a. As will be described in more detail below, in use, fluid may then flow from the front chamber 25 to the first valve outlet 21a, the second valve outlet 22a and the third valve outlet 23a.

[0058] The valve assembly 2a includes a first switching element 24a operable to allow selective fluid communication between the valve inlet 20a and the second valve outlet 22a, and a second switching element 24b operable to allow selective fluid communication between the valve inlet 20a and the third valve outlet 23a.

[0059] The first switching element 24a is actuated by the fluid pressure in the front chamber 25a. The first switching element 24a includes a first pressure relief valve 27a.

[0060] The second switching element 24b is actuated by the fluid pressure in the front chamber 25a. The second switching element 24b includes a second pressure relief valve 27b.

[0061] When the fluid pressure acting on the first switching element 24a is lower than the first threshold fluid pressure, the first pressure relief valve 27a is closed, and the first switching element 24a is said to be operated in the first mode. In the first mode, the first pressure relief valve 27a blocks the fluid communication between the front chamber 25a and the second valve outlet 22a. In the first mode, the front chamber 25a and the valve inlet 20a are fluidically connected to the first valve outlet 21a, and are not fluidically connected to the second valve outlet 22a.

[0062] In contrast, when the fluid pressure acting on the first switching element 24a reaches or exceeds the first threshold fluid pressure, the first pressure relief valve 27a opens and the first switching element 24a is said to operate in the second mode. When the first switching element 24a operates in the second mode, the front chamber 25a and the valve inlet 20a are fluidically connected to both the first valve outlet 21a and the second valve outlet 22a.

[0063] When the fluid pressure acting on the second switching element 24b is lower than the second threshold fluid pressure, the second pressure relief valve 27b is closed and the second switching element 24b is said to be operated in the first mode. In the first mode, the second pressure relief valve 27b blocks the fluid communication between the front chamber 25a and the third valve outlet 23a. In the first mode, the front chamber 25a and the valve inlet 20a are fluidically connected to the first valve outlet 21a and are not fluidically connected to the third valve outlet 22b.

[0064] In contrast, when the fluid pressure acting on the second switching element 24b reaches or exceeds the second threshold fluid pressure, the second pressure relief valve 27b is opened, and the second switching element 24b is said to be operated in the second mode. When the second switching element 24b is operated in the second mode, the front chamber 25a and the valve inlet 20a are fluidically connected to both the first valve outlet 21a and the third valve outlet 23a.

[0065] In one implementation, the second threshold fluid pressure may be higher than the first threshold fluid pressure. When the fluid pressure in the front chamber 25a acting on the first switching element 24a and the second switching element 24b is lower than the first threshold fluid pressure, the first switching element 24a operates in the first mode and the second switching element 24b operates in the first mode. When the fluid pressure in the front chamber 25a acting on the first switching element 24a and the second switching element 24b reaches or exceeds the first fluid pressure but does not reach or exceed the second fluid pressure, the first switching element 24a operates in the second mode and the second switching element 24b operates in the first mode. When the fluid pressure in the front chamber 25a acting on the first switching element 24a and the second switching element 24b reaches or exceeds the second fluid pressure, the first switching element 24a operates in the second mode and the second switching element 24b operates in the second mode.

[0066] The valve assembly 2a may include a first flow regulator (not shown) located downstream of the first outlet from the front chamber 25a and upstream of the first valve outlet 21a. The first flow regulator may be configured to limit the maximum flow rate output from the first valve outlet 21a. The first flow regulator may include a flow regulating geometry within the valve assembly 2a, such as a restrictor plate having one or more orifices therethrough.

[0067] The valve assembly 2a may include a second flow regulator (not shown) located downstream of the second outlet from the front chamber 25a and upstream of the second valve outlet 22a. The second flow regulator may be configured to limit the maximum flow rate output from the second valve outlet 22a. The second flow regulator may include a flow regulating geometry within the valve assembly 2a, such as a restrictor plate having one or more orifices therethrough.

[0068] In some implementations, a valve assembly can include any number of valve outlets.

[0069] In some implementations, there may be one less flow regulator than valve outlets. For example, in a valve assembly including four valve outlets (i.e., a first valve outlet, a second valve outlet, a third valve outlet, and a fourth valve outlet), there may be: a first flow regulator, which is located downstream of the first outlet from the front chamber and upstream of the first valve outlet, and is configured to limit the maximum flow rate output from the first valve outlet; a second flow regulator, which is located downstream of the second outlet from the front chamber and upstream of the second valve outlet, and is configured to limit the maximum flow rate output from the second valve outlet; and a third flow regulator, which is located downstream of the third outlet from the front chamber and upstream of the third valve outlet, and is configured to limit the maximum flow rate output from the third valve outlet.

[0070] The or each flow regulator may be configured to limit the maximum flow rate output from a given valve outlet downstream thereof.The or each flow regulator may comprise a flow regulating geometry within the valve assembly, such as a restrictor plate having one or more orifices therethrough.

[0071] The shower head 4a includes a shower face 3a, and the shower face 3a includes a first group of fluid delivery outlets 31a, a second group of fluid delivery outlets 32a, and a third group of fluid delivery outlets 33a. The first group of fluid delivery outlets 31a is located at the center of the shower face 3a. The second group of fluid delivery outlets 32a surrounds the first group of fluid delivery outlets 31a. The third group of fluid delivery outlets 33a surrounds the second group of fluid delivery outlets 32a.

[0072] The first set of fluid delivery outlets 31a is in fluid communication with a first chamber 41a behind the spray face 3a. The first chamber 41a is in fluid communication with the first valve outlet 21a.

[0073] The second set of fluid delivery outlets 32a are in fluid communication with a second chamber 42a located behind the spray face 3a. The second chamber 42a is annular and is in fluid communication with the second valve outlet 22a.

[0074] The third set of fluid delivery outlets 33a is in fluid communication with the third chamber 43a behind the spray face 3a. In the illustrated example, the third chamber 43a is annular and is in fluid communication with the third valve outlet 23a. It should be understood that other arrangements of the first chamber 41a, the second chamber 42a, and the third chamber 43a relative to each other may be adopted without departing from the scope of the present disclosure.

[0075] exist Figure 4 , a showerhead 4a is shown, wherein the first switching element 24a is operated in the second mode and the second switching element 24b is operated in the second mode. Therefore, the front chamber 25a and the valve inlet 20a are fluidically connected to the first valve outlet 21a, the second valve outlet 22a and the third valve outlet 23a. Therefore, the fluid is delivered through the first group of fluid delivery outlets 31a, the second group of fluid delivery outlets 32a and the third group of fluid delivery outlets 33a. The fluid output from the fluid delivery outlets is Figure 4 Indicated by the grey triangle 7a.

[0076] Bathing device 1a may further include a controller (not shown) for changing the flow rate from the fluid supply to valve port 20a. Changing the flow rate from the fluid supply can be used to change the fluid pressure acting on the first switching element 24a and the second switching element 24b to switch the first switching element 24a and the second switching element 24b between modes. Such a controller can be a digital controller, which is configured to change the flow rate from the fluid supply so that one or more of the first switching element 24a and the second switching element 24b: switches from the first mode to the second mode when the user actuates the digital controller; and switches from the second mode to the first mode after a predetermined time period (e.g., 30 seconds). Returning to a low (lower) flow rate mode after a predetermined time period can improve the economy of water use by providing a high (higher) flow rate spray mode to the user only in a limited time period specific to the desired purpose (e.g., shampooing).

[0077] Alternatively, the controller may also include a non-digital manually actuated valve (eg, provided with a lever, button, or rotatable dial for actuating the controller).

[0078] Figure 5 A valve assembly 2' for a bathing device or a plumbing device is shown. Figure 6 A cross-sectional view of a valve assembly 2' is shown.

[0079] The valve assembly 2' comprises an elongate body 9'. A first end 91 of the elongate body 9' is open and comprises a valve inlet 20' for receiving fluid from a fluid supply in use.

[0083] The switching device 24' comprises a bracket 241 received in the elongated chamber 25'. The bracket 241 is longitudinally movable in the elongated chamber 25'. The bracket 241 is tubular and has a plate 65' that blocks fluid communication from a first end 243 to a second end 244 of the bracket 241 along a central passage 242.

[0084] There are four holes 61' at locations along the length of the bracket 241 between the first end 243 and the plate 65', which are equally spaced around the circumference of the bracket 241. The holes 61' are arranged so that one of them can be aligned with one of the first valve outlet 21', the second valve outlet 22' and the third valve outlet 23', depending on the longitudinal position of the bracket 241 within the elongated chamber 25'.

[0085] The first O-ring seal 70' is received in a first annular groove 71' extending around the outer surface of the bracket 241. The first annular groove 71' is located near the first end 243 of the bracket 241. The first O-ring seal 70' provides a fluid seal between the outer surface of the bracket 241 and the inner surface of the elongated body 9'.

[0086] The second O-ring seal 70" is received in a second annular groove 71" extending around the outer surface of the bracket 241.

The third O-ring seal 70'" provides a fluid seal between the outer surface of the bracket 241 and the inner surface of the elongated body 9'.

[0088] The spring 80' is connected at a first end to the plate 65' and at a second end to an insert 81' which is fixed in a position within the elongated chamber 25' near the second end 92 of the elongated body 9'. The spring 80' is configured to orient the bracket 241 to a position such that one of the holes 61' is aligned with the first valve outlet 21' (e.g. Figure 6 shown) bias.

[0089] The inner surface of the elongated chamber 25' includes a step 251. The step 251 connects the wider portion of the elongated chamber 25' to the narrower portion of the elongated chamber 25'. The bracket 241 is disposed within the wider portion of the elongated chamber 25'. The insert 81' is located within the narrower portion of the elongated chamber 25'.

[0090] The valve inlet 20 ′, the first valve outlet 21 ′, the second valve outlet 22 ′ and the third valve outlet 23 ′ all have external threaded portions to facilitate connection to other portions of a pipeline.

[0091] Figure 6 2 shows the switching element 24' in a first mode. In the first mode, one of the holes 61' is aligned with the first valve outlet 21'. In the first mode, in use, fluid flows from the valve inlet 20' into the central channel 242 of the bracket 241 and flows through one of the holes 61' into the first valve outlet 21'. In the first mode, the bracket 241 is positioned to achieve a fluid connection between the valve inlet 20' and the first valve outlet 21', while preventing a fluid connection between the valve inlet 20' and both the second valve outlet 22' and the third valve outlet 23'.

[0092] The spring 80 ′ acts to prevent the carriage 241 from moving in its position in the first mode. Thus, the valve assembly 2 ′ is configured such that the flow from the valve inlet 20 ′ creates a reaction force in the spring 80 ′ that acts to hinder the movement of the carriage 241 .

[0093] When the fluid pressure acting on the switching element 24' reaches or exceeds the first threshold fluid pressure, the force of the fluid pressure acting on the plate 65' exceeds the first reaction force of the spring 80'. Due to this imbalance of forces, the bracket 241 translates along the length of the elongated chamber 25' until the other of the holes 61' is aligned with the second valve outlet 22', at which point the switching element 24' is said to be operating in the second mode.

[0094] In the second mode, the bracket 241 is positioned to enable fluid connection between the valve inlet 20 ′ and the second valve outlet 22 ′ while preventing fluid connection between the valve inlet 20 ′ and each of the first valve outlet 21 ′ and the third valve outlet 23 ′.

[0095] When the fluid pressure acting on the switching element 24' reaches or exceeds the second threshold fluid pressure (which is higher than the first threshold fluid pressure), the force of the fluid pressure acting on the plate 65' exceeds the second reaction force of the spring 80'. Due to this imbalance of forces, the bracket 241 translates along the length of the elongated chamber 25' until the other of the holes 61' is aligned with the third valve outlet 23', at which point the switching element 24' is said to be operating in the third mode.

[0096] In the third mode, the bracket 241 is positioned to enable fluid connection between the valve inlet 20' and the third valve outlet 23', while preventing fluid connection between the valve inlet 20' and both the first valve outlet 21' and the second valve outlet 22'. When the switching element 24' is in the third mode, the second end 244 of the bracket 241 abuts the step 251. Therefore, the step 251 prevents the bracket 241 from moving to a position other than the third mode.

[0097] Thus, the switching element 24' is actuated by fluid pressure and is configured to switch from operating in the first mode to operating in the second mode or the third mode (or vice versa) due to changes in fluid pressure. Such pressure-induced switching can provide a compact alternative to expensive and complex digitally controlled switching methods.

[0098] The valve assembly 2' may further include one or more check valves and / or pressure relief valves, each of which is arranged in an opening from the elongated chamber 25' to one of the first valve outlet 21', the second valve outlet 22', and the third valve outlet 23'. Each of the check valves and / or pressure relief valves may be configured to prevent backflow from one of the first valve outlet 21', the second valve outlet 22', and the third valve outlet 23' to the chamber elongated chamber 25'. Each of the check valves and / or pressure relief valves may also prevent leakage from one of the valve outlets 21', 22'.

[0099] The valve assembly 2' may include a first flow regulator (not shown) located downstream of the first outlet from the elongated chamber 25' and upstream of the first valve outlet 21'. The first flow regulator may be configured to limit the maximum flow rate output from the first valve outlet 21'. The first flow regulator may include a flow regulating geometry within the valve assembly 2', such as a restrictor plate having one or more orifices therethrough.

[0100] The valve assembly 2' may include a second flow regulator (not shown) located downstream of the second outlet from the elongated chamber 25' and upstream of the second valve outlet 22'. The second flow regulator may be configured to limit the maximum flow rate output from the second valve outlet 22'. The second flow regulator may include a flow regulating geometry within the valve assembly 2', such as a restrictor plate having one or more orifices therethrough.

[0101] In some embodiments, a valve assembly can include any number of valve outlets.

[0102] In some embodiments, there may be one fewer flow regulator than valve outlets.

[0103] The or each flow regulator may be configured to limit the maximum flow rate output from a given valve outlet downstream thereof.The or each flow regulator may comprise a flow regulating geometry within the valve assembly, such as a restrictor plate having one or more orifices therethrough.

[0104] Figure 7 , Figure 8 as well as Fig. 9 Another example of a bathing device 1' is shown. The bathing device 1' comprises Figure 5 to Figure 6 In this example, the device 1' comprises a shower head 4' for showering. Figure 7 As shown, the showerhead 4' comprises a device inlet 5' which is threaded to enable coupling to a fluid supply pipe (not shown). The valve assembly 2' is arranged to be fluidly coupled to the fluid supply pipe via the device inlet 5'.

[0105] The shower head 4' comprises a shower face 3', and the shower face 3' comprises a first group of fluid delivery outlets 31', a second group of fluid delivery outlets 32' and a third group of fluid delivery outlets 33'. The first group of fluid delivery outlets 31' is located at the center of the shower face 3', and the third group of fluid delivery outlets 33' is arranged at the periphery of the shower face 3'. The second group of fluid delivery outlets 32' is arranged on the shower face between the first group of fluid delivery outlets 31' and the third group of fluid delivery outlets 33', so that the first group of fluid delivery outlets 31' is surrounded by the second group of fluid delivery outlets 32', and both the first group of fluid delivery outlets 31' and the second group of fluid delivery outlets 32' are surrounded by the third group of fluid delivery outlets 33'.

[0106] The showerhead 4' further includes: a first chamber 41' configured to supply fluid to the first set of fluid delivery outlets 31'; a second chamber 42' configured to supply fluid to the second set of fluid delivery outlets 32'; and a third chamber 43' configured to supply fluid to the third set of fluid delivery outlets 33'. In this example, the second chamber 42' and the third chamber 43' are substantially annular. The second chamber 42' is arranged to surround the first chamber 41', and the third chamber 43' is arranged to surround the first chamber 41' and the second chamber 42'.

[0107] The device 1' is configured such that the first valve outlet 21' of the valve assembly 2' is in fluid communication with the first group of fluid delivery outlets 31' via the first chamber 41'. The device 1' is configured such that: the second valve outlet 22' is in fluid communication with the second group of fluid delivery outlets 32' via the second chamber 42'; the third valve outlet 23' is in fluid communication with the third group of fluid delivery outlets 33' via the third chamber 43'.

[0108] Figure 7 , a showerhead 4' is shown in which the switching element 24' of the valve assembly 2' is operated in its first mode. In this mode, the valve inlet 20' is fluidly connected to the first valve outlet 21' and is not fluidly connected to any of the second valve outlet 22' or the third valve outlet 23'. Therefore, the fluid is only supplied to the first set of fluid delivery outlets 31', and the showerhead 4' is said to be operating in the first spray mode. The fluid delivered by the first set of fluid delivery outlets 31' is represented by the gray triangle 7'.

[0109] Figure 8 24 'is shown when the fluid pressure acting on the switching element 24 'is higher than the first threshold fluid pressure but lower than the second threshold fluid pressure. At this fluid pressure, the switching element 24 'is in its second mode, wherein the bracket 241 ( Figure 6 ) is positioned so that the hole 61'( Figure 6) is aligned with the second valve outlet 22', thereby achieving fluid connection between the valve inlet 20' and the second group of fluid delivery outlets 32', while preventing fluid connection between the valve inlet 20' and each of the first valve outlet 21' and the third valve outlet 23'. Therefore, fluid is only supplied to the second group of fluid delivery outlets 32', and the spray head 4' is said to be operated in the second spray mode. The fluid delivered by the second group of fluid delivery outlets 32' is represented by the gray triangle 7".

[0110] Fig. 9 24 'is shown when the fluid pressure acting on the switching element 24 'is higher than the second threshold fluid pressure when the operation of the bathing device 1 '. At this fluid pressure, the switching element 24 'is in its third mode, wherein the bracket 241 ( Figure 6 ) is positioned so that the hole 61'( Figure 6 ) is aligned with the third valve outlet 23', thereby achieving fluid connection between the valve inlet 20' and the third group of fluid delivery outlets 33', while preventing fluid connection between the valve inlet 20' and each of the first valve outlet 21' and the second valve outlet 22'. Therefore, fluid is only supplied to the third group of fluid delivery outlets 33', and the spray head 4' is said to be operated in the third spray mode. The fluid delivered by the third group of fluid delivery outlets 33' is represented by the gray triangle 7"'.

[0111] In this way, the switching element 24' is actuated by fluid pressure and is configured to switch from operating in a first mode to operating in a second mode to operating in a third mode due to changes in fluid pressure, and vice versa. Therefore, the valve assembly 2' can be used as a diverter valve assembly, wherein the switching between the first valve outlet 21', the second valve outlet 22' and the third valve outlet 23' can be actuated by increasing and decreasing the fluid pressure (through a threshold fluid pressure). This can be more advantageous than conventional diverter valve assemblies, because conventional diverter valve assemblies can use fluid pressure to maintain a selected outlet, but cannot operate to switch the outlet when the pressure increases. Such traditional diverter valve assemblies generally require direct manual actuation or digital actuation of the valve itself. In contrast, the reversible pressure-induced spray mode switching described in the present disclosure can provide a compact alternative to traditional switching methods that generally require users to directly actuate the valve.

[0112] Although Figure 5 to Figure 6 The exemplary valve assembly 2' shown in FIG. 2 is described as having only three spray modes, but those skilled in the art will appreciate that the principles described herein may be scaled to include any number of valve outlets and corresponding spray modes.

[0113] The bathing device 1' may include a controller (not shown) for changing the flow rate from the fluid supply to at least one valve port 20'. Changing the flow rate from the fluid supply can be used to change the fluid pressure acting on the switching element 24', thereby switching the switching element 24' between modes. Such a controller can be a digital controller, which is configured to change the flow rate from the fluid supply so that the switching element: switches from a first mode to a second mode when the user actuates the digital controller; and switches from the second mode to the first mode after a predetermined time period (e.g., 30 seconds). Returning to the low flow rate mode after a predetermined time period can improve the economy of water use by providing the user with a high (higher) flow rate spray mode only for a limited time specific to the desired purpose (e.g., shampooing).

[0114] Additionally, the controller may include a non-digital, manually actuated valve (eg, provided with a lever, rotatable dial, or button for actuating the controller).

[0115] Fig.10 The system is shown installed in a bathing environment. The system 100 includes Figure 2 and Figure 3 The device 1 shown in FIG. A portion of the system 100 may be disposed behind a panel 101 of a bathing environment (eg, a shower panel wall). Fig.10 Features that may be located behind panel 101 are shown using dashed lines.

[0116] The system 100 includes a controller 110 for varying the flow rate from the fluid supply to the device 1. The system 100 further includes a mixing valve 102 operable to control the respective supply provided to the fluid supply pipe 10 by each of a hot fluid supply pipe 103a and a cold fluid supply pipe 103b (fluidly connected to a hot fluid source and a cold fluid source, respectively). The controller 110 includes a digital controller 111 electrically connected to the mixing valve 102 and operable to control the mixing valve 102. Thus, actuation of the digital controller 111 is operated to vary the flow rate within the fluid supply pipe 10. The valve inlet 20 ( Figure 2 , Figure 3 ) is configured to receive fluid from the fluid supply pipe 10 during use.

[0117] Changing the flow rate of the fluid supply can be used to change the effect on the switching element 24 ( Figure 2 , Figure 3 ) to actuate switching between spray modes of device 1.

[0118] The digital controller can be configured to vary the flow rate from the fluid supply so that the switching element ( Figure 2 , Figure 3): switching from the first mode to the second mode when the user actuates the digital controller 111; and switching from the second mode to the first mode after a predetermined period of time (e.g., 30 seconds).

[0119] Returning to a low(er) flow rate mode after a predetermined period of time may improve water economy by providing the user with a high(er) flow rate spray mode only for a limited time specific to the desired purpose (eg, shampooing hair).

[0120] Alternatively, the controller may include a manual (non-digital) controller (e.g., including a button, a rotatable dial, or a lever) configured to be manually actuated by a user to control the mixing valve 102 and to actuate the switching element 24 ( Figure 2 , Figure 3 ) is actuated to switch between the spray modes of the device 1.

[0121] exist Fig.10 In the illustrated example, system 100 is described as including Figures 2 to 3 However, those skilled in the art will appreciate that the device 1 may be replaced so that the system 100 may include any device according to the present disclosure, for example, Figure 4 The device 1a shown or Figures 7 to 9 The device 1' is shown.

[0122] Conventional shower systems can generally include a device for manually controlling the fluid pressure and / or flow rate of a shower head. The valve assembly of the present disclosure is configured so that the switching between the spray modes can be actuated by such a device for controlling the fluid pressure and / or flow rate. Therefore, the valve assembly can be easily retrofitted into a conventional shower system to increase the functionality of the shower system without installing a new controller. Compared with conventional spray mode switching devices, this single control switching can also reduce the maintenance cost and reliability of the shower system, while conventional spray mode switching devices are generally complex and may have many components that are prone to failure. For example, a digitally actuated valve in a shower head may be prone to failure because the shower head often leaks, is immersed in fluid and is in a high humidity environment. The valve assembly of the present invention does not require the shower head to be electrically connected to the controller. For the valve assembly of the present invention, the switching of the spray mode can be actuated via a remote digital controller or a manual controller (for changing the flow rate and / or fluid pressure) located upstream of the shower head. In this way, the valve assembly can have better reliability and convenience of spray mode actuation compared to traditional shower systems that rely on the shower head's digital valve control (within the shower head) or manually actuating the shower head itself to switch spray modes.

[0123] Figures 1 to 9The examples shown in show specific valve outlet positions and configurations of groups of chambers and corresponding fluid delivery outlets. However, those skilled in the art will recognize that a conduit can be used to deliver a flow from an outlet to a chamber and from a chamber to each group of fluid delivery outlets, so that the configurations of the valve outlets, chambers, and groups of fluid delivery outlets can be varied independently of one another while maintaining functionality. Therefore, the spray coverage associated with each spray mode can be tailored to suit a particular application. For example, a third group of fluid delivery nozzles can be positioned in the center / core of a spray face, and have a smaller coverage area on the spray face than the first group of fluid delivery outlets or the second group of fluid delivery outlets. The higher net flow rate associated with the third spray mode and the smaller spray face coverage of the third group of fluid delivery outlets can be used to generate high-speed flows, which may be useful in certain cleaning applications (e.g., shampooing). Those skilled in the art will appreciate that other configurations of fluid delivery outlets and chambers are also possible without departing from the scope of the present disclosure.

[0124] An object of the present invention is to at least partially ameliorate the problems of conventional multi-mode showerheads described in the preceding paragraphs.

[0125] A first aspect provides a bathing device or a plumbing device, comprising: a valve assembly, comprising: at least one valve inlet, which is configured to be connected to a fluid supply pipe; two or more valve outlets, the two or more valve outlets including a first valve outlet and a second valve outlet; a switching element, which is operable to selectively allow fluid communication between at least one inlet and the first valve outlet and / or the second valve outlet, wherein: when the fluid pressure acting on the switching element is lower than a threshold fluid pressure, the switching element operates in a first mode to allow fluid communication between at least one inlet and the first valve outlet and prevent fluid communication between at least one inlet and the second valve outlet; when the fluid pressure acting on the switching element is lower than a threshold fluid pressure, the switching element operates in a first mode to allow fluid communication between at least one inlet and the first valve outlet and prevent fluid communication between at least one inlet and the second valve outlet; When the fluid pressure on the element reaches or exceeds the threshold fluid pressure, the switching element operates in the second mode to allow fluid communication between at least one inlet and the second valve outlet; and the switching element is actuated by the fluid pressure and is configured to switch from operating in the first mode to operating in the second mode due to a change in fluid pressure through the threshold fluid pressure, and vice versa; a first group of fluid delivery outlets for providing a first spray mode, the first group of fluid delivery outlets being fluidly connected to the first valve outlet; and a second group of fluid delivery outlets, the second group of fluid delivery outlets being used to provide a second spray mode, the second group of fluid delivery outlets being fluidly connected to the second valve outlet.

[0129] The valve assembly may further comprise a front chamber connecting the at least one valve inlet to the first valve outlet.The front chamber may selectively connect the at least one valve inlet to the second valve outlet, for example via a pressure relief valve.

[0130] At least one of the two or more valve outlets may include a flow regulator configured to limit a maximum flow rate output from the valve outlet.

[0133] The or each flow regulator may include a check valve and / or a pressure relief valve.

[0134] The valve assembly may be configured such that when flow from the first valve outlet reaches a maximum flow rate output limit, fluid pressure acting on the switching element reaches or exceeds a threshold fluid pressure to open the pressure relief valve and switch the switching element to the second mode.

[0135] The valve assembly may include an elongated chamber selectively connecting the at least one inlet to the first valve outlet. The elongated chamber may selectively connect the at least one inlet to the second valve outlet.

[0136] The valve assembly may be configured such that when the switching element is operated in the second mode, the valve assembly prevents fluid communication between the at least one inlet and the first valve outlet.

[0140] The switching element may further comprise resilient means, such as a spring.The valve assembly may be configured such that flow from the at least one inlet creates a reaction force of the resilient means, which reaction force acts on the carrier.

[0141] The valve assembly may be configured such that the switching element switches from the first mode to the second mode when fluid pressure acting on the switching element overcomes a reaction force.

[0142] The two or more valve outlets may include one or more additional valve outlets, each additional valve outlet being associated with a corresponding additional mode of the switching element and an additional spray mode of the device. For example, the two or more valve outlets may include or be composed of three, four, five or more valve outlets.

[0144] The holes may include a first set of holes and a second set of holes offset from the first set of holes along the length of the movable bracket. The offset between the first set of holes and the second set of holes along the length of the movable bracket may be substantially equal to the offset between two of the valve outlets (e.g., between the first valve outlet and the second valve outlet) along the length of the elongated chamber.

[0145] When the switching element is in the first mode, at least one of the first set of apertures may be aligned with the first outlet, thereby achieving a fluid connection between the valve inlet and the first valve outlet.

[0146] When the switching element is in the second mode: at least one of the first group of holes can be aligned with the second valve outlet, thereby achieving fluid communication between the valve inlet and the second valve outlet; and at least one of the second group of holes can be aligned with the first valve outlet, thereby achieving fluid communication between the valve inlet and the first valve outlet.

Each of the grooves may have a length (measured along its long axis) greater than or equal to the offset between two of the valve outlets (e.g., between the first valve outlet and the second valve outlet) along the length of the elongated chamber.

[0148] When the switching element is in the first mode, at least one of the grooves may be at least partially aligned with the first outlet, thereby enabling fluid communication between the valve inlet and the first valve outlet. When the switching element is operated in the first mode, the valve assembly may be configured so that none of the grooves overlaps the second outlet, so that the second valve outlet is not in fluid communication with the valve inlet.

[0149] When the switching element is in the second mode: at least one of the grooves can be at least partially aligned with the second valve outlet, thereby realizing a fluid connection between the valve inlet and the second valve outlet; and at least one of the grooves can be at least partially aligned with the first valve outlet, thereby realizing a fluid connection between the valve inlet and the first valve outlet.

Returning to the low flow rate mode after the predetermined period of time can improve water economy by providing the user with a high (higher) flow rate spray mode only for a limited time specific to the desired purpose (e.g., shampooing).

[0174] A second aspect provides a system for installation in a bathing environment, comprising: an apparatus according to the first aspect; and a controller for varying the flow rate from the fluid supply to the apparatus.

[0175] The system may further include a mixing valve. The mixing valve is operable to control the respective supply provided by each of the two system fluid supply pipes to the fluid supply pipe. The two system fluid supply pipes may form part of the system and may include a hot fluid supply pipe fluidly connected to a hot fluid source and a cold fluid supply pipe fluidly connected to a cold fluid source.
