Description

Technical Field

[0001] The present disclosure relates to a water supply system and a method of controlling a water supply system, and more particularly to controlling water flow and temperature in the system. Background Art

[0002] Traditionally, a water supply system includes a hot water supply pipe, a cold water supply pipe, and a circulation pipe to ensure that users do not wait too long before getting water of an acceptable temperature at each tap. Summary of the Invention

[0003] It is an object of embodiments of the present disclosure to provide an improved water supply system.

[0004] It is another object of embodiments of the present disclosure to provide an improved method of controlling a water supply system.

[0005] According to a first aspect, the present disclosure provides a water supply system, comprising:

[0006] - Central water supply,

[0007] - Multiple taps;

[0008] - at least one operating device located at a tap,

[0009] - a piping system connecting the central water supply and the plurality of taps, the piping system including a separate flow path from the central water supply to each of the taps; and

[0010] - a controller for controlling the water flow from the central water supply device to the plurality of faucets and controlling the outlet water temperature of the water flow at the water outlet of the central water supply device;

[0011] Wherein the controller is located at the central water supply device, and wherein the controller is operable via the at least one operating device at the tap.

[0012] A non-pressurized water supply system is provided by providing a controller at the central water supply and operable via an operating device at the tap. The advantage of this non-pressurized water supply system is that in the event of a leak in the pipe system, only the water contained in the pipes from the central water supply to the tap will flow out of the building.

[0013] The water supply system may be a domestic water supply system for supplying domestic water in residential buildings such as single-family homes and apartments, a water supply system for supplying water in offices, industry, agriculture, healthcare (e.g., hospitals), or other water-using locations. The water supply system may additionally supply heating water to residential buildings, offices, industry, agriculture, healthcare (e.g., hospitals), or other locations requiring heating.

[0014] A central water supply can be a tank used to store water within a building where the water supply system is located. Alternatively, it can be a manifold, a building's water inlet, a common water storage unit used to supply multiple buildings, etc. The term "central water supply" refers to a tank / manifold / water inlet that can supply water to multiple taps in a building or multiple taps in multiple buildings.

[0015] The system includes multiple faucets. At these faucets, users can turn on the faucets to release water for drinking, bathing, cooking, cleaning, etc. In the context of the present invention, the term "faucet" encompasses not only traditional faucets in kitchens, bathrooms, other rooms with one or more faucets, and outdoor faucets, but also faucets in showers, bathtubs, whirlpools, hot tubs, and the like. Furthermore, the term "faucet" also encompasses toilets, bidets, washing machines, dishwashers, and the like. Therefore, a "faucet" can be any element inside or outside a building where water can be turned on to release water for drinking, bathing, cooking, cleaning, washing, flushing, and the like.

[0016] In an alternative embodiment, the water supply system can be used to supply water for heating, wherein the tap can alternatively encompass a radiator, floor heater or similar heater. Therefore, in the following, the term "tap" also encompasses a "heater".

[0017] An operating device is located at at least one faucet to allow a user to turn on the faucet to release water. "Operation" means, for example, starting and stopping the flow of water from the central water supply. The controller located at the central water supply and the operating device located at the faucet are two independent devices. The water supply system may include multiple operating devices. These operating devices can each operate the controller to control the flow of water to each faucet. In one embodiment, the operating device is located at each faucet. However, in an alternative embodiment, two or more faucets can share an operating device. As an example, a shower and a washbasin located in the same room may each include a faucet, but both faucets can be operated by a single operating device.

[0018] The operating device may be configured to generate an electrical demand signal, and the controller may be configured to receive the electrical demand signal and to control the water flow and outlet water temperature in response to the demand signal. The electrical demand signal may be communicated from the operating device to the controller via wireless communication. In an alternative embodiment, the communication may be wired communication.

[0019] A piping system connects a central water supply and a plurality of faucets. The piping system forms a water flow path from the central water supply to the plurality of faucets, wherein the piping system includes a separate flow path from the central water supply to each faucet. The piping system may be formed by a single pipe extending from the central water supply to the faucets. In one embodiment, the piping system may include multiple pipes.

[0020] The ductwork may be formed from polypropylene, different types of polyethylene, metal, or other suitable materials.

[0021] Typically, the tube has a circular cross-section. However, it will be appreciated that other cross-sections, such as an oval cross-section, a square cross-section, a triangular cross-section, or any other cross-section, may also be suitable.

[0022] The pipe diameter of the piping system with a circular cross section can be in the range of 5-100mm, or even larger. It should be understood that the diameter of the pipe connected to one faucet can be different from the diameter of the pipe connected to another faucet. In addition, it should be understood that the diameter of the piping system can vary. In residential buildings, the inner diameter of the pipe used to supply water to the faucet (for example, the inner diameter of the pipe in the kitchen or bathroom) is generally about 8mm and the outer diameter is about 12mm. It should be understood that pipes with other diameters may also be applicable. As an example, the size of the pipe may depend on the distance to the faucet, the amount of water expected to be used, the maximum flow rate required, etc.

[0023] The water supply system also includes a controller for controlling the flow of water from the central water supply to the plurality of faucets. In a simple embodiment, the controller can be adjusted between a fully open configuration and a closed configuration, thereby providing maximum flow (100% flow) or zero flow. In an alternative embodiment, the controller can be adjusted between a plurality of configurations allowing a plurality of different flow rates between maximum flow (100% flow) and zero flow.

[0024] The controller is located at the central water supply, where the flow rate is regulated. The controller can be operated via an operating device at the faucet, so that the user can operate the controller from the faucet. Communication between the controller and the operating device can be wireless, for example, by wireless communication using WIFI. As an example, the operating device can be attached to a wall, a wash basin, a cabinet, or other elements in the faucet area. In one embodiment, the size and shape of the operating device can allow the operating device to be built into a fixture for a traditional wall socket. The operating device can therefore be in a fixed position. In an alternative embodiment, the operating device can be a portable device.

[0025] In one embodiment, the operating device can be a mobile phone or other similar portable device. In a specific embodiment, the operating device can be formed by a mobile phone and the controller can be operated through an application (App) on the mobile phone. In an alternative embodiment, the operating device can be operated via a mobile phone or similar device.

[0026] To facilitate regulating the flow of water from the central water supply, the controller may include at least one flow regulator, such as a valve, for controlling the flow of water. Thus, the controller may include at least one of a valve, a motor, a PCB, and other components for controlling the flow and for communicating with an operating device.

[0027] The controller may include a separate flow regulator for each faucet, thereby controlling the amount of water to each faucet individually.

[0028] The controller is further configured to control the outlet temperature of the water flow at the water outlet of the central water supply. In one embodiment, the outlet temperature of the water flow can be controlled by mixing hot water and cold water at the central water supply, such as by mixing hot water and cold water in a water mixing chamber arranged in communication with the central water supply.

[0029] When controlling the outlet temperature of a water flow, the distance from the associated faucet can be taken into account to provide a water flow having a desired outlet temperature at the faucet. Thus, if the desired temperature at the faucet is the same, the outlet temperature of the water leaving the central water supply may be higher if the location of a particular faucet is far from the central water supply than the temperature of the water from a faucet closer to the central water supply.

[0030] To facilitate controlling the water temperature, the controller may include or may be in communication with a control unit that may include an algorithm configured to calculate a desired outlet temperature of water leaving the central water supply, depending on the desired water temperature at the tap and the distance between the tap and the central water supply.

[0031] Thus, the controller is configured to individually control the water flow from the central water supply to each faucet, and is additionally configured to individually control the outlet temperature of the water flowing from the central water supply to each faucet. In one embodiment, the flow regulator can be configured to control both the water flow and the outlet temperature of the water flow. This can be done individually for each faucet. In an alternative embodiment, the flow regulator and temperature regulator can be implemented as two separate devices.

[0032] The water supply system may include a measuring device configured to measure the outlet temperature of water at the outlet from the central water supply system. The measurement may be used to fine-tune the temperature of the water flowing at the outlet, as the measurement may be used as an input in a regulation algorithm of a controller, thereby facilitating the delivery of water at the desired temperature at the tap.

[0033] The central water supply may further include a circulation pipe for circulating water through the central water supply. This may help ensure that the water temperature at the central water supply remains above 55 degrees Celsius to reduce the risk of Legionella and may further help control the water temperature and therefore reduce the response time for delivering water of the desired temperature at the tap.

[0034] To facilitate individual control of water flow and temperature at each faucet, the piping system includes separate flow paths from the central water supply to each faucet.

[0035] An operating device may be located at each faucet, the operating device being configured to communicate with the controller to control the flow of water to the faucet and to control the temperature of the water. By arranging the operating device at each faucet, a user can control the flow and temperature of water flowing to the particular faucet at the faucet in question. It should be understood that the operating device may alternatively be used to control the flow and temperature of water at more than one faucet. These alternatives may be combined, whereby the system may include one or more operating devices, each located at a faucet, to operate the controller to control the flow and temperature of water flowing to a single faucet, and wherein the system may also include one or more operating devices, each located at a faucet, to operate the controller to control the flow and temperature of water flowing to one or more faucets.

[0036] The operating device may be configured to receive an operating signal in the form of at least one of a touch signal, an auditory signal, and a gesture signal, and to operate the controller based on the received signal. As an example, the operating device may include a touch panel to control the flow rate and / or temperature by tapping the panel and / or by applying pressure to the panel. In one embodiment, the touch panel may include multiple areas, each area specifying a specific amount and / or a specific temperature of water flow, thereby corresponding to multiple different user modes. In an alternative embodiment, applying pressure to a certain area will increase the temperature, while applying pressure to another area will decrease the temperature. Similarly, pressure in one area may increase the flow rate, while pressure applied to another area may decrease the water flow rate.

[0037] It will be appreciated that the above described possibility of applying user patterns from a plurality of specific areas of the device may be combined with the described application of pressure in certain areas.

[0038] In another embodiment, actions can be performed using audible signals. For example, commands of the form "warmer," "colder," "more," "less," "stop," and "start" can be used. Other commands may also be applicable. Predefined commands corresponding to user patterns can also be included, such as "brush teeth," "wash hands," or "shower," each of which corresponds to water flow at a specified temperature, at a specified flow rate, and for a specified duration. In one embodiment, a predefined command can be interrupted after the start of the command, for example, if the associated behavior is regretted.

[0039] In another embodiment, the operation can be performed by a gesture signal. The same type of event as described above can be achieved through gestures. For example, if the user's hand moves to the right, the water may be warmer.

[0040] It should be understood that the above commands are examples of commands, and other commands and / or additional commands may also be applied.

[0041] By applying audible and / or hand signals, the operating device can be operated without touching it, which can reduce the risk of germ transfer due to poor hygiene.

[0042] In one embodiment, at least two different types of signals may be combined.

[0043] The controller can communicate with a database containing a plurality of predetermined control strategies, each defining a requested water flow and a requested temperature. The predetermined control strategies can thus correspond to a variety of user modes, such as "brushing teeth," "washing hands," and "showering." Some predetermined control strategies can be stored in the database upon system installation, while others can be added by the user via a user interface. In one embodiment, not only can control strategies be added, but they can also be modified via the user interface. The controller can control at least one of the water flow and the temperature via the database. The operating device can be configured to select at least one of the predetermined control strategies.

[0044] For additional safety, the piping system can include coaxially arranged inner and outer pipes, with the outer pipe being configured to protect the inner pipe. If the inner pipe forming the water flow path is damaged, leaking water can be retained in the outer pipe without damaging the building. For further safety, leak monitoring can be implemented by using a piping system including inner and outer pipes, because a monitoring element can be arranged in the cavity between the inner and outer pipes. The monitoring element can be configured to provide an alarm if water is detected in the cavity. In one embodiment, the monitoring element can generate an alarm signal that can be sent to at least one of a controller, an operating device, a mobile phone, a monitoring device, or other device that can be read by a user or can provide an alarm to the user.

[0045] The water supply system may further include a monitoring unit for monitoring water usage. The controller may be configured to send a usage signal specifying water flow from the central water supply to the monitoring unit, and the monitoring unit may be configured to store the usage signal.

[0046] In one embodiment, the monitoring unit can be configured to store usage signals for each faucet separately. For example, the usage signals can be compared with previously stored usage signals (i.e., historical values) and / or with expected values. These comparisons can detect malfunctions, such as a leaking toilet that is continuously using water.

[0047] The controller may also be configured to send a temperature signal to the monitoring unit, which specifies the temperature of the water flow from the central water supply. The monitoring unit may also be configured to store the temperature signal, whereby correlated values ​​of flow rate and temperature may be monitored and stored in the monitoring unit.

[0048] The user may be able to log into the monitoring unit to access the monitored and stored usage signals and / or temperature signals.The monitoring unit may alternatively or additionally communicate with a mobile phone, other portable device, personal computer, or other user accessible device.

[0049] When monitoring flow and temperature, the system can identify that one or more sections of the pipe system are primarily exposed to water temperatures in the range of 20-45 degrees Celsius over a period of time. Since Legionella bacteria can be dangerous, this risk can be eliminated with the help of flow and temperature monitoring if temperatures do not regularly exceed 55 degrees. If this situation is detected during monitoring, the system can generate a warning signal / message. In response, the user can request that the water be heated to a temperature above 55 degrees and provided that water flows through the section of pipe in question, thereby killing any Legionella bacteria (if any) (Legionella flush). The system can include safety measures that ensure that the water is not heated when the user operates a controller at a tap located in the relevant pipe system.

[0050] Flow rate monitoring also makes it possible to calculate water consumption at each tap individually. Additional temperature monitoring allows for even more precise calculations. This is particularly useful in apartment and office buildings with multiple tenants.

[0051] In one embodiment, the central water supply can be fluidically connected to an additional supply device including an additional medium, wherein the supply of the additional medium to at least one faucet can be controlled by a controller. The additional medium can be a fluid, such as a gas or liquid medium. For example, the additional medium can be CO2, so that soda water / carbonated water can be provided. Another example of an additional medium can be a detergent, which is particularly applicable when the faucet is a washing machine or a dishwasher. In one embodiment, the additional medium can be water heated by a cooker, for example, to provide water at a temperature higher than the traditional hot water temperature provided by tap water. In embodiments of the water supply system used in industry, the additional medium can be, for example, oil or a colorant, such as a colorant for food or fabrics. Depending on the type of faucet, other media may also be applicable.

[0052] In one embodiment, the controller can be configured to simultaneously control the supply of water and the supply of an additional medium to at least one faucet. Thus, the controller can control the supply of water and the additional medium so that both are supplied simultaneously. Alternatively, simultaneous control can be achieved by alternating the supply of water and the additional medium.

[0053] The additional medium can be supplied to the faucet via a separate flow path from the central water supply to the faucet. The additional medium can be mixed with the warm and cold water in a water mixing chamber arranged in communication with the central water supply. In an alternative embodiment, the additional medium can be mixed with the warm and cold water in an additional mixing chamber arranged after the water mixing chamber, thereby allowing the additional medium to be added after the desired water flow and temperature are achieved. In another alternative, the additional medium can be added to the flow path via an inlet in the piping system without using an additional mixing chamber.

[0054] According to a second aspect, the present disclosure provides a method for controlling a water supply system, which includes: a central water supply device; multiple faucets; an operating device located at one faucet; a pipe system connecting the central water supply device and the multiple faucets, the pipe system including a separate flow path from the central water supply device to each faucet; and a controller for separately controlling the water flow from the central water supply device to at least one faucet and separately controlling the outlet water temperature of the water flow at the water outlet of the central water supply device, wherein the controller is located at the central water supply device; the method includes the step of operating the controller through the operating device at the faucet.

[0055] It should be understood that those skilled in the art will readily recognize that any feature described in conjunction with the first aspect of the present disclosure may also be combined with the second aspect of the present disclosure, and vice versa.

[0056] The water supply system according to the first aspect of the present disclosure is very suitable for performing the method steps according to the second aspect of the present disclosure. Therefore, the above description on the water supply system is also applicable to the method.

[0057] According to a third aspect, the present disclosure provides a controller for controlling the flow of water in a water supply system, the controller comprising: an operating device for receiving user demands; a flow regulator for controlling the flow in the water supply system and a temperature regulator for controlling the outlet temperature of the water flow at the water outlet of a central water supply device; and a communication device for communicating with the operating device, wherein the controller is constructed to control the water flow and the outlet temperature of the water flow at the water outlet of the central water supply device based on the demands received from the operating device.

[0058] The flow regulator and the operating device can be two independent devices, and the flow regulator can be configured to be located at a central water supply. The operating device can be arranged at a faucet, where a user can provide user demand to control the water flow and, in one embodiment, also the temperature of the water.

[0059] The flow regulator and temperature regulator can be a single regulating unit, as shown in the example below.

[0060] It should be understood that those skilled in the art will readily recognize that any features described in conjunction with the first and second aspects of the disclosure may also be combined with the third aspect of the disclosure, and vice versa.

[0061] The controller according to the third aspect of the present disclosure is very suitable for the water supply system according to the first aspect, and is very suitable for performing the method steps according to the second aspect of the present disclosure. The above description on the water supply system and method is therefore also applicable to the controller.

[0062] In one embodiment, the flow regulator may include two independent regulating elements that are movable relative to each other. The water inlet of the flow regulator may include a hot water inlet and a cold water inlet. When at least one of the regulating elements is moved, the opening ratio can be adjusted, thereby adjusting the flow rate and temperature of the water leaving the flow regulator. The hot water inlet and the cold water inlet may be located on one side of the regulating element, while the water outlet of the flow regulator may be located on the opposite side of the regulating element.

[0063] The flow regulator may include a drive element, such as a motor, which may be configured to move at least one of the regulating elements relative to another of the regulating elements. In an embodiment, the drive element may be a stepper motor.

[0064] In one embodiment, one of the regulating elements is fixedly mounted in the flow regulator, while the other regulating element is mounted so as to be movable. Fixed mounting may be denoted as a fixed regulating element, while mounting so as to be movable may be denoted as a movable regulating element.

[0065] Each of the regulating elements may include one or more openings. By moving the regulating elements relative to each other, the overlap between the one or more openings in the fixed regulating element and the one or more openings in the movable regulating element may be varied, thereby varying the flow rate and / or temperature.

[0066] In one embodiment, the fixed regulating element may include two openings, one opening in fluid communication with the hot water inlet of the flow regulator and the other opening in fluid communication with the cold water inlet of the flow regulator. The openings may have the same size and / or shape.

[0067] The movable adjusting element can include two openings, four openings, six openings, eight openings, ten openings, or even more openings (e.g., 20 openings or 30 openings). At least some of the openings can have different sizes. In one embodiment, the openings are identical in pairs. The flow rate through the flow regulator can depend on the overlap between the openings in the fixed adjusting element and the openings in the movable adjusting element. This overlap can also determine the temperature of the water flow.

[0068] By providing a different number of openings, openings of different sizes and / or shapes, and regulating elements having different sizes and / or shapes, the flow rate and water temperature can be varied. BRIEF DESCRIPTION OF THE DRAWINGS

[0088] It should be understood that the detailed description and specific examples, while indicating embodiments of the disclosure, are given by way of illustration only, since various changes and modifications within the spirit and scope of the disclosure will become apparent to those skilled in the art from this detailed description.

[0089] Figure 1 An embodiment of a water supply system 1 is shown. The water supply system 1 comprises a central water supply 2 and at least one faucet 3. In the illustrated embodiment, the system includes five different faucets 3: BR for a bathtub, HV for a washbasin, and KV for a kitchen sink. An operating device 4 is located at each of the faucets 3.

[0090] The piping system 5 connects each of the faucets 3 and the central water supply 2. The piping system 5 forms a water flow path from the central water supply 2 to each of the faucets 3. The piping system 5 is formed of separate pipes that extend from the central water supply 2 to each of the faucets 3 to form a separate flow path to each of the faucets 3.

[0091] The water supply system 1 further comprises a controller 6 for controlling the water flow from the central water supply device 2 to the tap 3 and for controlling the water temperature. The controller 6 is located at the central water supply device 2 and can be operated by the operating device 4 at the tap 3.

[0092] In the embodiment shown, the water supply system 1 is arranged in a single-family house 7 , viewed from above.

[0093] Figure 2 1 shows part of an embodiment of a water supply system 1. Each of the boxes 100 includes six individual controller elements 6' (see Figure 3 、 4 and 5). Each controller element 6' forms part of a controller 6 for controlling water flow and controlling water temperature. The piping system 5 forming a separate water flow path from the central water supply 2 to each of the taps 3 is shown by a portion of a separate pipe extending from each of the boxes 100.

[0094] Figure 3 FIG. 1 shows a portion of an embodiment of a controller 6 for a water supply system 1. The controller 6 includes six individual flow regulators 14, each including a valve chamber (see FIG. Figure 14 ), two regulatory elements (see Figure 11A and 11B )) and a stepper motor 16. A hot water inlet 17A and a cold water inlet 17B are located above to provide hot and cold water to each flow regulator. The piping system 5, which forms a separate water flow path from the central water supply 2 to each of the faucets 3, is connected at the outlet 18. At the outlet 18, a pipe (not shown) is connected through a valve that allows manual closure of the individual pipes for repair, maintenance, or emergency situations.

[0095] Figure 4 and Figure 5 Shown Figure 3 Parts of the controller 6 are shown.

[0096] Figure 6 FIG. 1 shows a portion of a controller 6 for controlling the flow of water in one embodiment of a water supply system 1. In the embodiment shown, the controller 6 includes six separate housing elements 10, three manifolds 12, and six flow regulators in the form of valves 14 (see FIG. Figure 3), wherein a valve 14 is located in each individual housing element 10. Thus, the controller 6 shown is configured to control the flow of water to six taps 3. The piping system 5 forming the water flow path from the central water supply 2 to each of the taps 3 is shown by a portion of an individual pipe extending from each of the housing elements 10.

[0097] The hot and cold water inlets are represented by two valves 13 .

[0098] Figure 7 The flow of water through the controller 6 for the water supply system 1 is schematically shown. Hot water and cold water are supplied to each flow regulator 14 through a hot water inlet 17A and a cold water inlet 17B. A common hot water pipe 117A supplies hot water, while a common cold water supply pipe 117B supplies cold water. In the flow regulator 14, the hot water and the cold water are mixed to provide water with a requested temperature and flow rate. In the embodiment shown, the flow regulator 14 includes a regulating element (see also Figure 11A and 11B ) and a stepper motor, as described below with respect to Figures 10-14.

[0099] Figure 7 The controller 6 shown in FIG also includes an additional valve 114 to allow additional medium to be supplied to at least one faucet. In the embodiment shown, additional medium can be supplied to each faucet because the additional valve 114 is arranged to communicate with each flow regulator 14. A common additional medium pipe 117C supplies additional medium.

[0100] Water and additional media are supplied to each tap via a separate water outlet 18 .

[0101] In the embodiment shown, a separate flow meter FM and temperature sensor TS are provided at each water outlet 18, thereby providing the ability to monitor water consumption for both flow and temperature.

[0102] Figure 8 Shown in exploded view Figure 6 Parts of the controller 6 are shown. Two valves 14 can be attached to the manifold 12 and each of the valves 14 can be covered by a separate housing element 10.

[0103] Figures 9A-9C Shown during maintenance / repair Figure 6 The various parts of the controller 6 are shown.

[0104] Figure 9A The replacement and / or adjustment of components of the valve 14 is shown. The replacement / adjustment can be performed by opening the housing element 10.

[0105] Figure 9BShown is the replacement of the entire control element 6 ′ of the controller 6 . The entire control element 6 ′ can be removed by loosening four screws 11 and the tube 5 .

[0106] Figure 9C A partial replacement of a valve 14 is shown, wherein the valve 14 is first removed from the control unit 6 and then repaired.

[0107] Figures 10A-10C An embodiment of a flow regulator 14 in the form of a valve is shown. The flow regulator 14 comprises a valve chamber 14A, 14B, two regulating elements 15A, 15B (see also Figure 11A and 11B ), and a stepper motor 16. The stepper motor 16 is configured to move one of the adjustment elements 15B relative to the other adjustment element 15A. It should be understood that the stepper motor in another embodiment can be replaced by another type of motor or drive element capable of moving at least one of the adjustment elements.

[0108] The water inlet of the flow regulator 14 includes a hot water inlet 17A and a cold water inlet 17B. By moving one of the regulating elements 15B, the opening ratio is adjusted, thereby adjusting the flow rate and temperature of the water leaving the flow regulator 14. The hot water inlet 17A and the cold water inlet 17B are located on one side of the regulating elements 15A and 15B, while the water outlet 18 of the flow regulator 14 is located on the opposite side of the regulating elements. A mixing chamber 118 is formed on the opposite side of the regulating elements 15A and 15B.
