Definitions
- the invention relates to a use of a hot water tank, a method and a corresponding device for operating a service water system for vehicles.
- the invention further relates to a service water system for vehicles with a hot water tank, as well as an assembly for use in a service water system.
- Hot water systems for vehicles so for example for use in mobile homes, caravans or watercraft, often have hot water storage, which must be emptied for hygienic reasons or to protect against frost damage during longer downtime. This can be done, for example, by opening a drain valve arranged at a location as low as possible so that
- Water from the hot water tank or pipes can drain.
- the invention is characterized by a use of the existing hot water tank in the vehicle as a pressure accumulator for air, so as to blow water pipes free.
- This has the advantage that no residual liquid remains in the hot water tank and the water pipes. This can prevent germination of the hot water tank and the water pipes. Furthermore, frost damage in the hot water tank and the water pipes can be avoided. As a result, failures and maintenance of the hot water tank and the water pipes can be avoided. Overall, a cost-effective operation of the hot water tank can be achieved.
- the invention is characterized by a method and a corresponding one
- Device for operating a service water system for vehicles with a hot water tank.
- a valve located downstream of the hot water tank is closed.
- air is pumped into the hot water storage tank to build up a predetermined pressure in the hot water storage tank.
- the valve located downstream of the hot water storage tank is opened to expel water from the water heater Hot water system by means of pressurized air in the hot water tank.
- the invention is characterized by a service water system for vehicles, which has a hot water tank, and a valve arranged downstream of the hot water tank, which is designed to interrupt a fluid flow downstream of the hot water tank. Upstream of the hot water tank, a compressor is arranged, which is adapted to pump to build up a predetermined pressure in the hot water tank air in the hot water tank.
- Hot water system can be avoided. Accordingly, cost-effective operation of the service water system can be achieved.
- the maximum pressure of the compressor is less than the maximum allowable
- a check valve is arranged downstream of the compressor and upstream of the hot water storage tank, by means of which a fluid flow from the hot water storage tank into the compressor can be prevented.
- air or other gas can be introduced by means of the compressor in the hot water tank, while penetration of water or other liquids can be prevented in the compressor.
- a damage to the compressor can be avoided by a liquid.
- the invention is characterized by an assembly for use in a service water system, comprising a compressor, a check valve, an on / off switch, hoses and hose connectors.
- the single figure shows a schematic representation of the service water system.
- the figure shows a service water system 10, which can be used in particular for vehicles, for example for campers, caravans or watercraft.
- the hot water system 10 has a hot water tank 12.
- the hot water tank 12 is designed in particular as a hot water boiler.
- the hot water tank 12 has walls, which are preferably formed from a plastic.
- the Walls of the hot water tank 12 made of a metal, in particular made of stainless steel or aluminum.
- a designed as a pipe line 14 of the hot water tank 12 is coupled to a compressor 16.
- the line 14 is designed in particular as a water line.
- the compressor 16 is disposed upstream of the hot water storage 12. By means of the compressor air or other gas can be pumped into the hot water tank 12 to build in this a predetermined gas pressure, so that the
- Hot water tank 12 is designed as an accumulator.
- the compressor 16 is designed in particular as an oil-free compressing compressor, so as to avoid contamination of the service water system 10 with oil.
- a check valve 18 is hydraulically disposed between the compressor 16 and the hot water tank 12.
- the check valve 18 allows the supply of air compressed in the compressor 16 in the water water storage 12, but prevents a liquid such as water from the water water storage 12 can get into the compressor 16.
- the hot water tank 12 is connected to another line 20 coupled.
- a valve 22 is arranged in the further line 20. If the further line 20 is designed in particular as a water drain line, the valve 22 can serve to to empty the hot water tank 12 by water flows through the open valve 22 through the further line 20.
- the service water system 10 may have a plurality of further lines 20 with valves 22, for which the shown further line 20 with the valve 22 is exemplary.
- a liquid F may remain in the hot water storage 12 and in the further line 20 even after emptying the hot water storage tank 12. This is particularly the case when the further line 20 can not be installed with a slope relative to the valve 22, or if the vehicle in which the service water system 10 is arranged, can not be aligned exactly horizontal.
- air or another suitable gas is pumped into the hot water storage tank 12 via the line 14 by means of the compressor 16 until a predetermined pressure in the hot water storage tank 12 has been reached.
- the hot water tank 12 is thus used as an accumulator for air or the other gas.
- the compressor 16 is designed so that the maximum pressure capacity of the compressor 16 is smaller than the maximum allowable operating pressure of the hot water If the walls of the hot water tank 12 are formed from a plastic, an internal pressure in the hot water tank 12 is limited to 1 bar in particular. If the walls of the hot water storage tank 12 are made of a metal, then the maximum operating pressure of the hot water storage tank 12 is preferably limited to 1.9 bar.
- the valve 22 is opened, and the liquid F can be expelled by means of the compressed air or the compressed gas from the hot water tank 12 and the further line 20, and thus from the entire process water system 10.
- the expulsion of the liquid F from the further lines 20 preferably takes place in such a way that the valves 22 are opened and closed again one after the other so as to supply the liquid F together with the compressed air from the hot water storage via the further lines 20 12 and the other lines 20 drive out.
- the expulsion of the liquid F from the hot water tank 12 and the further line 20 allows to prevent bacterial contamination in the further line 20 and in the hot water tank 12. Furthermore, it can be avoided that by leaving the liquid F in the lines 20 and in the hot water tank 12 freezes water at low temperatures.
- the advantage of the invention is that the number of failures of the service water system 10 and repair can be kept low on the domestic water system 10, and can be avoided in a complaint for the manufacturer costs incurred.
