Definitions
- the invention relates to a device for hot water treatment, especially for household applications by heat recovery from wastewater, preferably from wastewater from a sink and / or a dishwasher or washing machine, by means of a heat pump, in particular a compression heat pump, with a wastewater collecting wastewater tank and a hot water tank, said the evaporator of the heat pump is in thermal contact with the waste water tank and the condenser of the heat pump is in thermal contact with the hot water tank.
- a heat pump in particular a compression heat pump
- Such devices make it possible to extract the heat energy present in the waste water of domestic applications before this wastewater is discharged into the sewage system.
- a device is known from EP 0 088 055 A1, wherein the device described therein contains a waste water collection container, which allows the temporary storage of warm water, further, a heat pump, the energy of the warm wastewater and extracts a container, the storage of hot water is used.
- the invention has for its object to improve a device of the type mentioned in that deposits of dirt particles avoided in Abwasserbehalter and thus optimal heat transfer through the wall of the wastewater container is ensured. This object is achieved according to the invention in that the waste water tank is provided with a stirrer.
- the advantage achieved by the invention consists essentially in the fact that the agitator keeps the wastewater in the waste water tank in motion, so that deposits on the wall of the waste water tank can not or at best occur to a small extent. In particular, thereby any anti-contamination coatings on the inner wall are superfluous.
- the agitator also ensures a circulation of the water in the wastewater tank, whereby a faster withdrawal of the heat energy contained in the wastewater is possible, so that a heat gradient is avoided from the middle of the waste water tank to the edge. Furthermore, the agitator can simultaneously perform a pumping or transport function for the wastewater.
- the waste water tank is designed as a cylindrical hollow body with a waste water inlet and a waste water drain, wherein the agitator is formed by a coaxial in the waste water tank output shaft arranged thereon stirring elements.
- the stirring elements can be designed in any suitable form, for example as stirring blades; it has proven to be advantageous in the context of the invention, when the stirring elements are designed as a screw, as a result, a transport function is exercised.
- the stirring elements can advantageously also be constructed so that they form a closure for the wastewater.
- a valve may also be provided as a closure for the wastewater at the wastewater outlet. This valve will stay first closed until the waste water has been cooled to an intended lower temperature value.
- the stirring elements are formed so that they rest against the wall surface of the wastewater tank or with a small gap.
- the drive shaft can be driven by a motor in a particularly simple embodiment.
- the drive shaft with the stirring elements and the motor are designed as an assembly which can easily be removed from the waste water container for cleaning purposes.
- the wastewater tank is arranged obliquely with a slope to the wastewater drain.
- the invention provides that a feed heat exchanger for the fresh water is provided on the waste water tank.
- this flow heat exchanger is formed by a helically extending around the housing of the wastewater pipe coil.
- the coil of the flow heat exchanger and the coil of the evaporator are arranged in the manner of a common bifilar winding. Further, it has proven to be advantageous if the inlet of the hot water tank is provided in the lower region and connected to the outlet of the flow heat exchanger. In this way, the warm water can accumulate in the upper area of the hot water tank without being mixed with the incoming fresh water, so that the hot water is ready for removal in the upper area. Therefore, it is also recommended that the condenser and the hot water drain are located in the upper part of the hot water tank.
- the waste water tank, the heat pump and the hot water tank are enclosed by a common heat insulation.
- the entire device thus forms a unit which can replace the usual electric boiler under the sink.
- the reproduced in the drawing device is intended in particular for household applications to extract from the wastewater of a sink and / or dishwasher or washing machine contained therein heat energy and supply a powered by fresh water hot water tank 4.
- a sewage collecting wastewater container 1 and a heat pump are first provided, which is designed here as a compression heat pump with a compressor 13.
- the evaporator 2 of the heat pump is with the waste water tank 1 and the condenser 3 of the heat pump with the hot water tank 4 in thermal contact.
- the waste water tank 1 is provided with a stirrer.
- the waste water tank 1 is formed in the embodiment as a cylindrical hollow body and formed both with a waste water inlet 5 and with a waste water drain 6.
- the agitator has a coaxial in the waste water tank 1 extending drive shaft 7, are arranged on the stirring elements 8.
- These stirring elements 8 can be formed as individual stirring blades or also - in a manner not shown - in front of a screw. Further, such designs are possible in which the stirring elements 8 form a closure for the wastewater.
- a valve 9 is provided as a closure for the wastewater, which allows emptying of the waste water tank 1, as soon as the heat energy stored in the wastewater is withdrawn to a sufficient extent.
- the stirring elements 8 are, as the drawing can be seen, formed so that they either the rest of the wall surface of the waste water tank 1, which requires a certain elasticity of the stirring elements 8 or this stand with a small gap.
- the drive shaft 7 is - as can be seen from the drawing - driven by a small electric motor 10, which - in view of the only small circulation capacity - can be designed for low energy consumption.
- a small electric motor 10 which - in view of the only small circulation capacity - can be designed for low energy consumption.
- the drive shaft 7 with the stirring elements 8 and the motor 10 may be formed as an easily removable unit, in order to facilitate in this way an occasionally necessary cleaning of the waste water tank 1.
- the waste water tank 1 is arranged obliquely within the device with a slope to the waste water drain 6, whereby the transport of dirt particles to the waste water drain 6 is facilitated.
- a feed heat exchanger 1 1 is provided for the fresh water at the waste water tank 1.
- This flow heat exchanger 1 1 is formed by a helically extending around the housing of the wastewater tank 1 tube coil. Between the individual turns of the coil of the flow heat exchanger 1 1, the coil of the evaporator 2 is arranged in the manner of a common bifilar winding.
- the output of the flow heat exchanger 1 1 is connected to the inlet of the hot water tank 4, wherein this inlet is arranged in the lower region of the hot water tank 4, so that the cooler fresh water accumulates in the lower part of the hot water tank 4.
- the condenser 3 and the hot water outlet are in the upper part of the hot water tank 4, so that a mixing of the incoming cold fresh water and the hot water to be removed at the outlet is largely avoided.
- the waste water tank 1, the heat pump and the hot water tank 4 are - as indicated in the drawing - surrounded by a common heat insulation 12 - whereby the entire device, moreover, forms a compact unit that replaces the usually arranged below a sink hot water boiler.
