Definitions

  • Devices and methods for delivering additives to showerheads for application to the human body are known, for example from EP 2543779 A2 , or WO 2007/062536 A1 .
  • US 2019/352889 A1 discloses a washing facility with multiple outlets for dispensing water or a water admixed with a consumable. It is controlled to operate in different operating modes, which can differ in the pressure, flow rate, temperature and whether the consumable is admixed to the water or not.
  • WO 2012055272 A1 shows a liquid soap delivery device with a liquid suction chamber. Therein, delivery of the soap is driven by hydraulic pressure of water being delivered.
  • the water conditioning unit is for use in a washing device, the water conditioning unit being configured to provide, controlled by a user, water at different flow rates and with different spraying characteristics and with additives admixed to the water, the water conditioning unit comprising
  • the water conditioning unit is configured to provide at least one additive without mixing it with water.
  • one or more or all of the docking adapters are designed to receive an additive cartridge or capsule.
  • the additive cartridge or capsule can contain the additive in solid form or in a highly viscous form.
  • the additive cartridge or capsule can comprise an amount of additive required for a single treatment cycle. That is, a treatment cycle for one user in one sitting.
  • the docking adapter can be configured to guide water through the additive cartridge, thereby eroding the additive and carrying it along out of the additive cartridge.
  • the docking adapter can comprise a slot into which the additive cartridge or capsule is inserted, and then mechanically opened by the docking adapter.
  • a refillable additive container that forms part of the dispensing unit is present.
  • the total manifold is shaped to form at least one flow restrictor for restricting a flow rate through one of the internal channels of the total manifold.
  • the flow through the high-flow water channel does not pass through any elements designed to reduce or limit the flow, except for the high-flow water channel.
  • an initial spray flow path leads from the inlet fitting to a branching point, where it branches into a spray water channel and an admixing channel,
  • a pressure reducer is arranged to limit a pressure at a branching point, where it branches into a spray water channel and an admixing channel, in particular to a pressure of less than three bar, in particular to a pressure of two bar.
  • the pressure reducer is one of the hydraulic elements carried by the total manifold.
  • a flow restrictor is arranged to further limit a flow in the spray water channel, in particular to a flow between one and two litres per minute.
  • the total manifold further comprises a mixing manifold arranged on or being part of the second plate, the mixing manifold comprising an admixing channel arranged to guide a flow of water from the second end to the first end, with additive inlets, optionally comprising additive check valves, arranged along the admixing channel for admixing additives to the flow of water.
  • the additive check valves can be duckbill valves.
  • a volume of the admixing channel, from the first additive inlet, seen in the direction of flow, to the junction, is less than thirty millilitres, in particular less than twenty millilitres, in particular less than ten millilitres.
  • This relatively small volume leads to a short delay time between the moment that an additive is delivered to the admixing channel and the time that it is delivered to the junction and then to the showerhead. Conversely, it also leads to a short delay time between the moment in which delivery is stopped and the time at which the additive is flushed from the admixing channel.
  • the water conditioning unit comprises two or more peristaltic pumps arranged in a row, with their axes of rotation at least approximately at a right angle to a direction of the admixing channel, wherein two outermost peristaltic pumps of the row are arranged to turn in opposite directions.
  • all hydraulic elements guiding and controlling a flow of water between the inlet fitting and the outlet fitting are arranged inside a compact base unit
  • the base unit is configured for the, one, two or more additive containers to be inserted into and connected to corresponding docking adapters in a vertical direction, in particular in a downward direction.
  • the base unit is configured for three or more additive containers arranged in a line to be inserted into and connected to corresponding docking adapters in a vertical direction, in particular in a downward direction.
  • the base unit comprises user interface elements comprising additive selecting elements, in particular one selector button for each docking adapter or additive source, and an additive concentration controller for setting an amount of additive delivered from one or more selected docking adapters or additive sources when the water conditioning unit is in an additive dispensing mode, and optionally dispensing mode selecting elements, and optionally indicator elements, in particular indicator light rings, indicating the one or more selected docking adapter or additive source.
  • additive selecting elements in particular one selector button for each docking adapter or additive source
  • an additive concentration controller for setting an amount of additive delivered from one or more selected docking adapters or additive sources when the water conditioning unit is in an additive dispensing mode
  • optionally dispensing mode selecting elements and optionally indicator elements, in particular indicator light rings, indicating the one or more selected docking adapter or additive source.
  • mode indicating elements can be present, indicating that the one or more selected docking adapter or additive source is either in continuous admixing, pulses additive admixing mode or pulsing water admixing mode.
  • a mode can be indicated, for example, by a colour or pattern of brightness variation of an optical indicator.
  • the user interface is configured to allow for more than one docking adapter or additive source to be selected, and a controller is configured to, for a particular setting of the additive concentration controller
  • a non-claimed corresponding method for operating the water conditioning unit comprises the steps of
  • the selection of two or more docking adapters for operation in an admixing state can result in the mixing of two or more additives that undergo a chemical reaction upon being mixed.
  • the mixing of these additives can be done in the same proportion, that is, each docking delivering the same amount of product per time unit, or the same proportional part of the total amount.
  • the device can be configured to control the amount of each additive delivered for these chemical reactions.
  • the device can be configured to generate a user alert signal indicating that a given total amount of additives has been dispensed.
  • the dispensing unit not claimed, is in particular for use in combination with the water conditioning unit of the preceding claims. It comprises a showerhead with a spray outlet and a high-flow outlet,
  • the dispensing unit comprises an additive button for selecting an operation mode of the mixer valve and the plain water valve for the water conditioning unit to deliver either water through the spray water channel, or water admixed with additive through the admixing channel.
  • the dispensing unit comprises a flow selector for selecting an operation mode of the high-flow valve and the mixer valve or plain water valve, as the case may be, for the water conditioning unit
  • the flow selector is configured to operate a diverter to guide a flow of water from the hose
  • FIG. 1 schematically shows a structure of flow paths through the washing device 10.
  • Water from a water supply for example a mains water supply and via a faucet 1, enters the washing device 10 through an inlet fitting 11. It passes through a filter 12.
  • the optional path of the high-flow water channel represented by a dashed line.
  • the flow in the high-flow water channel 24 is controlled by a high-flow valve 21.
  • a pressure elevating pump for example, a gear pump 14 can be connected in parallel to or instead of the inlet one way valve 13.
  • This pressure elevating pump can be present if the washing device 10 is foreseen to be used in a setting when the mains water supply pressure is too low. In other settings, the pressure elevating pump can be omitted. In the usual case, the pump is not present.
  • the water then passes through a flow meter 16, or, alternatively, a parallel arrangement of a flow meter 16 and an internal bypass 17, represented by a dashed line. If the internal bypass 17 is present, most of the water passes through the bypass, so that the flow meter 16 has a small influence on the flow rate.
  • the flow optionally passes through a pressure reducer at location 18' and, at a branching point 223, splits up into separate branches, an admixing channel 22 and a spray water channel 23, and, as in the embodiment shown, the high-flow water channel 24.
  • the optional pressure reducer at location 18' acts as a flow limiter, so that the flow rate through the subsequent elements is independent of a mains water pressure, in settings where no pressure elevating pump is present.
  • the flow into each of these channels is controlled by an associated valve, that is, a mixer valve 19 and a plain water valve 20 and a high-flow valve 21.
  • the flow passes through a flow restrictor or pressure reducer 221 into an admixing section where it is joined by one or more additive flows.
  • the flow restrictor or pressure reducer 221 reduces the flow, or further reduces the flow if the pressure reducer at location 18' is present.
  • Each of the additive flows is delivered by an associated peristaltic pump 26 from an associated additive container 25 into the admixing channel 22 through an associated additive check valve 27.
  • the additive check valve 27 can be a duck bill valve. In embodiments, the additive check valve 27 is not present.
  • volume of the spray water channel 23 can be between thirty and sixty millilitres, in particular between forty and fifty millilitres.
  • the volume of the high-flow water channel 24 can be between ten and thirty millilitres, in particular between fifteen and twenty-five millilitres.
  • the hydraulic assembly 50 comprises a total manifold 57 which in turn comprises a base manifold 55 connected to a mixing manifold 56.
  • the base manifold 55 in turn comprises a first plate 51 and second plate 52.
  • channels 54 are formed by recesses in the plate.
  • the channels 54 run in parallel to a plane, called channel plane.
  • a gasket 53 can be arranged to ensure water tightness between the two plates in regions where the channels 54 are located.
  • the channels in the base manifold 55 implement the channels of the spray water channel 23 and leading into it, and of the high-flow water channel 24.
  • the high-flow water channel 24 branches off from the initial spray flow path 222 prior to measurement elements, as shown by the dashed line in Figure faucet 1.
  • Figure 2 shows an overview of the hydraulic assembly 50, seen from the side at which most of the hydraulic elements are attached to the base manifold 55.
  • Figure 3 shows the same side, but with the first plate 51 removed, leaving the gasket 53 on the second plate 52, showing the location of channels 54 relative to the hydraulic elements.
  • Figure 3 shows, on the left side, just the gasket 53 on the second plate 52, and on the right side, the first plate 51, flipped over to show the channels 54.
  • Figure 5 shows different views of the opposite side, illustrating the arrangement of the mixing manifold 56 comprising the admixing channel 22: a solid view, a view with a wireframe representation of the mixing manifold 56, and a sectional view.
  • FIG. 7 shows details of the dispensing unit 3, in particular of the showerhead 34.
  • the showerhead 34 comprises two distinct outlets, a spray outlet 37 and a high-flow outlet 38.
  • the spray outlet 37 is configured to create a spray of water by creating two or more colliding jets of water. Methods and devices, in particular cartridges for generating such a spray are described, for example, in
  • the spray outlet 37 thus generates a fine spray of water, optionally comprising an additive. This allows to apply the additive and perform effective wetting and rinsing operations using relatively little water.
  • the high-flow outlet 38 is arranged to dispense water at a significantly higher flow rate than the spray outlet 37.
  • the high-flow outlet 38 comprises a ring-like outlet opening surrounding an outlet opening of the spray outlet 37.
  • the washing device 10 is configured, in a spray state, to have a flow rate through the spray outlet 37, without additives, of between two and three litres per minute, in particular 2.5 litres/minute +/- 20%.
  • This flow rate can be controlled by the pressure reducer 18. This flow passes through the spray water channel 23.
  • the washing device 10 is configured, in an admixing state, to have a flow rate through the spray outlet 37, with additives, of between one and two litres per minute, in particular 1.5 litres/minute +/- 20%.
  • This flow rate can be controlled by the flow restrictor 221.
  • This flow passes through the admixing channel admixing channel 22.
  • the admixing state can be implemented as one of the following substates or admixing modes, or the washing device 10 can be configured, for at least one of the additives, to switch between two or more of the following admixing modes:
  • the washing device 10 is configured, in a high-flow state, to have a flow rate through the high-flow outlet 38 of between five and nine litres per minute, depending on the water pressure at the inlet fitting 11.
  • this flow rate can be, for an inlet pressure of
  • Operation of the showerhead 34 is controlled by means of an additive button 35 and a flow selector 36. Both are control elements for setting operation modes of the water conditioning unit 2 through electrical signal lines, and are typically are arranged on the showerhead 34. In other embodiments, one or both are arranged on a sink or treatment chair, on a base unit 75, or in a foot pedal.
  • the additive button 35 controls operation of the valves in the water conditioning unit 2 to open the mixer valve 19 and close the plain water valve 20 when the additive button 35 is activated to be in an "admixing" position.
  • the opposite valve position is set in a "plain water” position. Typically, this is the default position in which the additive button 35 is not activated.
  • the flow selector 36 controls operation of the valves in the water conditioning unit 2 to open the high-flow valve 21 and close the mixer valve 19 and plain water valve 20 when the flow selector 36 is activated to be in a "high-flow” position.
  • the high-flow valve 21 is closed in a "normal flow” or “spray” position. Typically, this is the default position in which the flow selector 36 is not activated.
  • the showerhead 34 switches between spray outlet 37 and high-flow outlet 38. This can be done by the flow selector 36 mechanically or electrically actuating a diverter 39 that diverts the flow from the hose 33 to either the spray outlet 37 or the high-flow outlet 38, depending on the state of the flow selector 36.
  • the flow selector 36 controls the valves of the water conditioning unit 2 by a dedicated signal line, e.g. carrying an electrical signal.
  • a sensor such as a Hall sensor can be arranged to detect the position of the flow selector 36.
  • the flow selector 36 indirectly controls the valves in that a change in pressure or flow caused by the flow being diverted to the high-flow outlet 38 is detected by a corresponding sensor in the water conditioning unit 2.
