DESCRIPTION OF THE PREFERRED EMBODIMENTS "DEVICE FOR THE PRODUCTION OF HOT WATER"

Technical Field The present application describes a device for the production of hot water.

BACKGROUND ART A device for the production of hot water with at least one continuous water heater, which is provided to heat a first flow of water during a filling procedure, and with at least one additional flow unit, which is provided for the at least temporary provision of a second flow of water by means of the continuous water heater immediately after the completion of the filling procedure.

DISCLOSURE OF THE INVENTION The present invention is based on a device for the production of hot water, with at least one continuous water heater, which is provided for heating a first flow of water during a filling procedure, and with at least one flow unit which is provided for at least temporary provision of a second flow of water by means of the continuous water heater immediately after the completion of the filling procedure. It is suggested that the additional flow unit is provided for storing at least one energy during the supply procedure and for at least partially using the energy stored after the completion of the supply procedure for the provision of the second flow of water.

By "intended" shall be understood to be particularly specifically programmed, arranged and / or equipped. Because an object is intended for a specific function, it should be understood in particular that the object fulfills and / or performs this specific function in at least one state of application and / or operation. The continuous water heater is realized as a gas operated continuous water heater. More particularly, the continuous water heater has at least one gas burner which is provided to generate a thermal energy for heating the first water stream during the filling procedure. More particularly, the gas burner is intended to be connected at the beginning of the filling procedure, to be operated during the filling procedure and to be disconnected after completion of the filling procedure. Further, the continuous water heater has at least one heat transfer element which is provided to transmit the thermal energy generated by the gas burner at least partially to the first water stream to be heated during the filling procedure. More particularly, the heat transfer element is percolated by the first stream of water to be heated during a filling procedure.

Because the additional flow unit is provided for a "temporary provision of a water flow" it is particularly to be understood that the additional flow unit is provided to generate a flow of water for at least a defined period of time, in order to maintain at least partially a stream of water and / or to at least partially reverse the flow of water. By a "second water flow" is meant a water flow which is intended to percolate at least temporarily the continuous water heater, particularly a continuous water heater heat exchanger, upon completion of a supply procedure . More particularly, the second water flow is provided to at least partially evacuate residual thermal energy existing following a continuous water heater supply procedure, particularly a continuous water heater heat exchanger. The additional flow unit features a power storage unit, which is provided for storing at least a power temporarily during a filling procedure. The energy to be stored can be at least essentially recovered from a process performed during the filling process, particularly in the form of kinetic, thermal or electrical energy. More particularly, the energy storage unit is provided to transmit the energy stored during the supply procedure immediately after the completion of the supply procedure at least partially for the provision of the second flow of water.

Due to such an embodiment, such a device with improved operational properties can be provided. More particularly, due to the availability of the second water stream, an overheating and / or a calcification of the continuous water heater, particularly of the continuous water heater heat exchanger, can be advantageously avoided. In addition, a power required for a second flow of water can be advantageously stored during a filling procedure, so no additional power supply is required, particularly from an external power source.

Further it is suggested that the additional flow unit is provided for storing a kinetic energy of at least one fluid flow during the filling procedure. More particularly, the energy storage unit of the additional flow unit may have at least one energy storage device, for example a flywheel, a flywheel storage device, a spring storage device and / or a device for the storage of kinetic energy. More particularly, the energy storage unit has at least one energy absorber, which is provided to at least partially absorb the kinetic energy of the fluid flow and to transfer it to the energy storage device. The energy absorber can be realized for example as a flywheel or as a wheel-propeller arranged at least partially in the fluid flow. Further it is suggested that the fluid flow is formed by at least the first water stream. Alternatively or additionally it is suggested that the fluid flow is formed by at least one exhaust gas flow, particularly an exhaust gas flow from the continuous water heater. Therefore, energy which is necessary for the provision of the second water flow after the completion of the filling procedure during a filling procedure can advantageously simply be stored.

Further it is suggested that the additional flow unit has at least one additional flow pump, which is provided at least partially for the provision of the second flow of water. More particularly, the energy stored during the filling procedure is intended to drive the additional flow pump, in particular the pump flywheel or the pump impeller of the additional flow pump upon completion of the filling procedure. Therefore, the second flow of water after the completion of the filling procedure can be advantageously made simple.

Further it is suggested that the additional flow pump is provided for the drive by the first flow of water during the filling procedure. More particularly, the first flow of water during the filling procedure is provided to drive a pump flywheel or a pump impeller of the additional flow pump. More particularly, the additional flow pump is performed at least partially integrally with the energy storage unit. More particularly, a pump flywheel or a pump impeller is realized integrally with an energy absorber of the energy storage unit. Therefore the energy to be stored can be advantageously absorbed by means of the additional flow pump, whereby no additional energy absorber is required.

Further it is suggested that the device has a bypass line connecting an inlet line with an outlet line of the continuous water heater. During a filling procedure the inlet line is provided to feed the first flow of water for heating in the continuous water heater. The outlet line during a filling procedure is provided to evacuate the first flow of water from the continuous water heater after heating. Upon completion of the dispensing procedure the second water flow is provided to circulate at least temporarily in an inlet line loop, continuous water heater, outlet line and bypass line. Therefore, after the completion of the filling procedure, the remaining thermal energy of the continuous water heater can advantageously be evacuated.

According to a preferred embodiment of the present invention it is suggested that the additional flow pump is arranged in the inlet line or in the outlet line. Preferably the additional flow pump is arranged in the inlet line. Accordingly, an advantageously simple arrangement of the additional flow pump can be achieved.

Further it is suggested that the device has a valve unit which is provided to at least a wide flow of water through the bypass line during the filling procedure. More particularly, the valve unit may comprise at least one three-way valve and / or a one-way valve, in particular a check valve. More particularly, the valve unit is disposed at least partially in the branch line. The valve unit is provided to allow a flow of water through the bypass line upon completion of the filling procedure.

According to another embodiment of the present invention it is suggested that the additional flow pump is arranged in the branch line. Accordingly, a valve unit can advantageously be dispensed with, which is intended to avoid at least a large amount of water flow through the bypass line during the filling procedure.

It is further suggested that the branch line has a smaller line diameter than the entry line and / or the mackerel line. Accordingly, a pressure drop in the inlet line and / or the mackerel line during a filling procedure can be advantageously minimized.

Further it is suggested a process with a device for the production of hot water, wherein a first flow of water is heated by means of a continuous water heater during a filling procedure and wherein a second flow of water is provided by means of the continuous water heater immediately after the completion of the supply procedure wherein at least one energy is stored during the supply procedure and wherein the energy stored after completion of the supply procedure is used at least partially for the provision of the second water flux. Due to the availability of the second water stream, an overheating and / or a calcification of the continuous water heater, particularly of a continuous water heater heat transfer element, can be advantageously avoided. In addition, the energy required for the provision of the second water stream may be advantageously stored during a filling procedure, so no additional power supply is required, particularly from an external power source. The device for the production of hot water according to the present invention should not be limited to the application and the embodiment described above. More particularly, the device for producing hot water according to the present invention may have a number of elements, components and units different from that referred to herein for achieving the mode of operation described herein.
