Description

Title: Water tap, building comprising the water tap and method using the water tap Description According to a first aspect, the present disclosure relates to a water tap.
According to a second aspect, the present disclosure relates to a building comprising the water tap according to the first aspect of the present disclosure.
According to a third aspect, the present disclosure relates to a method for providing hot water to a user using a water tap according to the first aspect of the present disclosure.
A known water tap for providing hot water to a user is arranged for receiving a first fluid flow comprising relatively hot water and a second fluid flow comprising relatively cold water. The hot water and the cold water is mixed in the water tap for achieving a predetermined temperature and outputting the water from the water tap at a temperature related to the predetermined temperature to a user.
A drawback of the known water tap is that via the known water tap Legionella bacteria may spread.
An objective of the present disclosure is to provide a water tap arranged for providing hot water to a user with a relative low risk of spreading the Legionella bacteria.
The objective is achieved by providing a water tap comprising: - a water inflow arranged for receiving, by said water tap, water, preferably cold water, from a water supply: - a heat exchanger arranged for receiving and discharging a heating fluid and heating, by said heating fluid, preferably via a wall of said heat exchanger, said water received, in use, by said water tap, via said water inflow; and
- a tap outflow, communicatively coupled via said heat exchanger for fluid flow to said water inflow, arranged for supplying said hot water to said user.
The present disclosure relies at least partly on the insight that hot water supplied to the known water tap, for instance via piping provided in a house, may be a source of Legionella bacteria. In particular, the Legionella bacteria may dwell in water that resides in the piping of a building after halting supply of the hot water to the water tap. It is known that the Legionella bacteria multiplies relatively rapidly in a temperature range of 32 to 42 degrees Celcius. Growth of the Legionella bacteria, when using the known water tap, may be avoided by heating the water above a temperature above 60 degrees Celcius before providing the hot water at a predetermined temperature to the user. By providing the heat exchanger, contact between the hot water supplied to the user and the heating fluid for heating the water supplied to the water tap is avoided thereby avoiding the risk of spreading Legionella bacteria via hot water that may be present in piping of the building. By supplying the water tap with water from a water supply, preferably a water supply comprising relatively cold water, the risk of spreading Legionella bacteria is relatively low since Legionella bacteria does not, or only at a relative low rate, grow in cold water.
The present disclosure further at least partly relies on the insight that a pressure difference between a hot water supply and a cold water supply may result in a relative unstable supply of water from the known water tap. In particular, in case a variation of the pressure of the hot water supply differs from a variation of the pressure of the cold water supply, the known water tap may provide a relative unstable supply of water as regards a temperature thereof.
Within the context of the present disclosure, hot water is to be understood as water having an elevated temperature relative to a temperature of the water when being supplied to a building for instance by a water company. In general the hot water may have a temperature below 55 degrees Celcius. Preferably, hot water is to be understood as water having a temperature in the range of 30 to 45 degrees Celcius.
In this regard, it is beneficial if said water inflow comprises a water inflow element arranged for attaching said water tap to a wall of a building.
Preferably, said heat exchanger comprises: - a heating fluid inlet arranged for receiving, by said heat exchanger, said heating fluid; and - a heating fluid outlet arranged for discharging, by said heat exchanger, said heating fluid.
In this regard, it is beneficial if said water tap comprises a heating fluid inlet element, communicatively coupled for fluid flow to said heating fluid inlet and a heating fluid outlet element, communicatively coupled for fluid flow to said heating fluid outlet, wherein said heating fluid inlet element and/or said heating fluid outlet element are arranged for attaching said water tap to a wall of a building.
It is advantageous if said heat exchanger is a counter-flow heat exchanger. A counter-flow heat exchanger is beneficial for realising a relative high output temperature of the water while using heating fluid having a relative low temperature.
Preferably, said heat exchanger is a double separated heat exchanger. This is beneficial for avoiding, or at least significantly reducing the risk, of the heating fluid to contact the water in case of damage of the heat exchanger..
It is beneficial if said water tap is arranged for holding a volume of said water, in use, between said water inflow and said tap outflow in the range of 0.05 to 10 dm?®, preferably in the range of 0.05 to 3 dm? more preferably in the range of
0.05 to 1 dm?. The present disclosure relies at least partly on the insight that water supplied to the water tap, preferably cold water, may be a source of Legionella bacteria when the water remains in the water tap after heating by the heating fluid. By providing a volume of said water in use, between said water inflow and said tap outflow in the range of 0.05 to 10 dm3, preferably between 0.05 to 3 dm?, more preferably in between
0.05 to 1 dm? the risk of spreading Legionella bacteria is reduced from the water remaining in the heat exchanger after halting outflow of hot water from the tap to the user.
Preferably, said water tap comprises a flow rate setting arrangement arranged for setting a flow rate of said water received from said water supply. This is beneficial for allowing the user to set a flow rate of the hot water from the tap outflow.
It is advantageous, if said water tap comprises a release valve for releasing said water, in use present in said water tap, from said water tap. Providing the release tap is beneficial for removing water in water tap, or at least in the heat exchanger thereof, after halting outflow of hot water from the tap to the user. This is beneficial for avoiding, or at least reducing the risk of, presence of Legionella bacteria in the water tap.
Preferably, said release valve is arranged for removing said heating fluid from said heat exchanger.
Preferably, said release valve is positioned at a side of the water tap that, in use, is below said water and/or said heating fluid for allowing to drain said water tap from said water and/or said heating fluid by force of gravity.
It is advantageous, if said release valve is arranged such that in a condition of said water tap wherein said flow rate is zero said release valve releases said water from said water tap. This is beneficial for releasing a relative reliable water tap as regards avoidance of Legionella presence in said water tap.
Preferably, said water tap comprises a multi-way valve, such as a three-way valve, forming part of said release valve and said flow range setting arrangement.
It is beneficial if said water tap comprises a temperature setting arrangement arranged for setting a temperature of said hot water. This is beneficial for allowing a user to set said temperature of said hot water to a preferred temperature.
In this regard, it is beneficial if said temperature setting arrangement comprises a thermostatic valve. This is beneficial for realising a relative stable temperature of said hot water exiting said water tap via said tap outflow. The thermostatic valve is arranged such that the thermostatic valve reduces a flow of the 5 heating fluid through the heat exchanger when said water is heated in said heat exchanger to a temperature above a temperature set and increases a flow of the heating fluid through the heat exchanger when said water is heated in said heat exchanger to a temperature below a temperature set.
In an embodiment of the water tap according to the present disclosure, said temperature setting arrangement comprises a valve arranged for manually setting a flow rate of said heating fluid through said heat exchanger.
Preferably, said water tap comprises a water flow detector arranged for detecting said receipt of said water via said water inflow and further arranged for outputting a signal upon receipt of said water via said water inflow. This is beneficial for allowing a heating fluid source to be activated for providing said heating fluid to the water tap.
It is beneficial, if said water tap comprises a flexible conduit communicatively coupling for fluid flow said tap outflow to said heat exchanger.
In this regard, it is advantageous if said tap outflow is moveably and/or releasably connected to said heat exchanger. This is beneficial for, in use, adjusting a position of the tap outflow for instance in relation to a ground surface of the building.
Preferably, the water tap is arranged for allowing said tap outflow to slide along the heat exchanger and removable locking of the tap outflow to the heat exchanger.
According to the second aspect, the present disclosure relates to a building comprising a water tap according to the first aspect of the present disclosure, a water supply arranged for supplying said water to said water tap and a heating fluid source, wherein said water supply is communicatively coupled for fluid flow to said water inflow of said water tap and said heating fluid source is communicatively coupled for fluid flow to said heating fluid inlet.
Embodiments of the building correspond to embodiments of the water tap according to the first aspect of the present disclosure. The advantages of the building correspond to the advantages of the water tap according to the first aspect of the present disclosure presented previously.
In this regard, it is beneficial if said heating fluid source is communicatively coupled for fluid flow to said heating fluid outlet for returning, in use, said heating fluid to said heating fluid source. This beneficial for realising a relative high energy efficiency. The heating fluid exiting the heat exchanger via the heating fluid outlet may have a relative high temperature requiring only a relative small amount of heating before feeding again to the heat exchanger of the water tap.
In an embodiment, the flow rate of the heating fluid through the water tap is higher than the flow rate of the water supplied to the water tap. This is beneficial for realising a relative small temperature drop inside the heat exchanger of the heating fluid. A relative small temperature drop of the heating fluid is beneficial for allowing a relative high energy efficiency.
In an embodiment of the building according to the second aspect, said water flow detector is communicatively coupled to said heating fluid source and said heating fluid source is arranged for providing said heating fluid to said water tap upon receipt of said signal from said water flow detector.
According to the third aspect, the present disclosure relates to a method comprising the steps of: - providing a building according to the second aspect of the present disclosure; - providing water from said water supply to said water tap; - heating, by said heating fluid source, said heating fluid to a temperature in the range of 40 to 80 degrees Celcius, preferably in the range of 40 to 50 degrees Celcius, more preferably in the range of 45 to 50 degrees Celcius;
- supplying, by said heating fluid source, said heated heating fluid to said heat exchanger of said water tap. Embodiments of the method correspond to embodiments of the building according to the second aspect of the present disclosure. The advantages of the method correspond to the advantages of the building according to the second aspect of the present disclosure presented previously. The present disclosure will now be explained by means of a description of a preferred embodiment of a water tap according to the present disclosure, a building comprising the water tap and a method for providing hot water using the water tap in which reference is made to the following schematic figures, in which: Fig. 1: a front view of a water tap according to the present disclosure is shown; Fig. 2 -3: side views of the water tap from Fig. 1 are shown; Fig. 4: a top view of the water tap from Fig. 1 is shown; Fig. 5: a cross-section of an element of the water tap from Fig. 1 is shown; Fig. 6: a building according to the present disclosure is shown; Fig. 7: a method according to the present disclosure is shown.
Water tap 1 is arranged for providing a user, such as a resident of a house 101, with hot water via a tap outflow 9. The water tap 1 may for instance be used as a tap in a shower facility or kitchen. The water tap 1 comprises a water inflow 3 for allowing water from a water supply 103 to be received by the water tap 1. The water inflow 3 is provided with a water inflow element 15. The water inflow element 15 may be provided as a tubular element and arranged for attaching the water tap 1, via the water inflow element 15, to a wall (not shown) of the building 101. The water inflow 3 is communicatively coupled for fluid flow with the tap outflow 9 for allowing water from the water source 103 to reach the user.
Water tap 1 further comprises a heat exchanger 5. The heat exchanger 5 is arranged for receiving and discharging a heating fluid such as water or oil.
To this end the heat exchanger 5 is provided with a heating fluid inlet 13 and a heating fluid outlet 11. The heating fluid inlet 13 is arranged for receiving, by the heat exchanger 5, the heating fluid.
The heating fluid outlet 11 is arranged for discharging, by the heat exchanger 5, the heating fluid.
The heating fluid inlet 13 is provided with a heating fluid inlet element 17 and the heating fluid outlet 11 is provided with a heating fluid outlet element 19. Both the heating fluid inlet element 17 and the heating fluid outlet element 19 may be provided as tubular elements and arranged for attaching the water tap 1, via the heating fluid inlet element 17 and the heating fluid outlet element 19, to the wall of the building 101. The heating fluid may enter the heat exchanger 5 via the heating fluid inlet 13 and exit the heat exchanger 5 via the heating fluid outlet 11 without getting into contact with the water that is to be supplied by the water tap 1 to the user.
In other words, the heating fluid is maintained separated in the heat exchanger 5 from the water that is to be supplied to the user and any mixing between the heating fluid and the water that is to be supplied to the user is avoided.
The heating fluid, in use present in the heat exchanger 5, may heat water that is to be supplied to the user and, in use, present in the heat exchanger 5 between the tap outflow 9 and the water inflow 3 via a wall 7 of the heat exchanger 5. Water tap 1 further comprise a flow rate setting arrangement 21 and a temperature setting arrangement 23. The flow rate setting arrangement 21 is arranged for setting a flow rate of said water received from said water supply 103. The flow rate setting arrangement 21 may comprises a three-way valve 27 for opening and closing the water inflow 3. In the open condition, the valve 27 may be set at different positions via an actuation element (not shown) for setting the flow rate.
The valve 27 is further arranged as a release valve for releasing water from the water tap 1 when the valve 27 is closed.
In other words, water that may be present in the water tap 1 between the water inflow 3 and the tap outflow 9 is allowed to drain from the tap via valve 27 if the valve 27 is in the closed position as regards the supply of water from the water source 103.
The temperature setting arrangement 23 comprises a thermostatic valve 25 for allowing to set a temperature of the hot water. The thermostatic valve 25 is arranged such that a flow rate of the heating fluid through heat exchanger 5 is controlled by the thermostatic valve 25. By controlling the flow rate of the heating fluid, heating of the water, by the heating fluid, that is to be supplied to the user may be controlled thereby controlling the temperature of the water that is to be supplied to the user. Water tap 1 further comprises a water flow detector 29 arranged for detecting receipt of water via the water inflow 3. The water flow detector 29 is further arranged for outputting a signal upon receipt of the water via the water inflow 3 and for being communicatively coupled to a heating fluid source 105 for providing the signal to the heating fluid source 105 and controlling supply of the heating fluid to the water tap 1 from the heating fluid source 105.
Building 101 comprises water tap 1, the water supply 103 and the heating fluid source 105. The water supply 103 is communicatively coupled for fluid flow to the water inflow 3 of the water tap 1 and the heating fluid source 105 is communicatively coupled for fluid flow to said heating fluid inlet 11 and the heating fluid outlet 13. The heating fluid is maintained in a closed circuit with the heating fluid source 105. The water flow detector 29 is communicatively coupled to the heating fluid source 105. The heating fluid source 105 is arranged for providing said heating fluid upon receipt of the signal from said water flow detector 29. In an alternative embodiment the water flow detector 29 is provided in piping of the building communicatively coupling for fluid flow the water supply 103 with the water tap instead of providing the water flow detector in the water tap. Method 201 is arranged for providing hot water to the user. The method 201 comprises a step 203 of providing a building 101 and a step 205 of providing water from the water supply 103 to the water tap 1. During a step 207 of method 201, the heating fluid is heated by the heating fluid source 105 to a temperature in the range of 40 to 50 degrees Celcius and supplied during a step 209 to the heat exchanger 5 of the water tap 1 for heating the water that is to be supplied to the user.
