Advantageous variants and refinements of the invention result from the following secondary claims.

The advantages that can be achieved with the invention are that a treatment liquid for treating laundry can be heated by saving energy using a heat pump blender. This is an advantage over electrically heated devices, in which all the heating energy is taken from the electricity grid, since the electric current is currently the most expensive kind of energy and damages the environment due to the expulsion of CO2 of power plants. The energy efficiency as a whole is in an apparatus that uses the approach described here, rather than in an apparatus that obtains all the necessary heat from an electric heater. An equipment for heating a treatment liquid for an apparatus for treating laundry, in particular an automatic washing machine or a clothes dryer, has the following characteristics:

a circulation interface of the inlet side, to provide the treatment liquid from a laundry treatment chamber of the apparatus for treating the laundry;

a vaporizer configured to vaporize a liquid cooling medium using a fluid to provide thermal energy and provide it as a gas cooling medium;

a blender, configured to heat the treatment liquid using the gas cooling medium and provide it as a heated treatment liquid and

a circulation interface on the outlet side to evacuate the heated treatment liquid into the laundry treatment chamber.

Under an apparatus for treating laundry can be understood as an apparatus in which laundry can be treated, for example textile garments. Under laundry treatment it can be understood, for example, to wash or dry. During operation of the apparatus for treating the laundry, the laundry may be located in the laundry treatment chamber and treated using the treatment liquid. The circulation interface on the inlet side is suitable for receiving the treatment liquid from the laundry treatment chamber or from another tank. Under treatment liquid it can be understood for example a detergent liquid for washing. To heat the treatment liquid a heat pump can be used, which takes the fluid, for example air or liquid, to heat the treatment liquid. The vaporizer, the blender and a cooling medium circuit that includes the cooling medium can be part of such a heat pump. By using the technology of heat pumps for a washing process and / or a drying process, little electrical energy is consumed. According to the invention, the equipment presents a process air interface on the inlet side to provide process air from the laundry treatment chamber. In this regard, the blender or other blender is configured to heat the process air using the gas cooling medium and provide it as heated process air. The equipment also has a process air interface on the outlet side to evacuate the heated process air to the laundry treatment chamber. In this way, the air can be taken from the laundry treatment chamber, heated and returned to the laundry treatment chamber, to heat the laundry treatment chamber.

According to one embodiment, it can be the apparatus for treating laundry a clothes dryer. If a clothes dryer is used for the drying process, then the energy efficiency of the clothes dryer increases. If the heat pump is also used to heat the detergent liquid when washing, it increases the efficiency even more.

environment air interface 110 or process air interface 206 with the vaporizer 112. The vaporized cooling medium in the vaporizer 112 is conducted in the first service state through a refrigerant medium circuit 116 to the blender 114 and is used by the blender 114 to heat the treatment liquid. In the second state of service, the vaporized cooling medium in the vaporizer 112 is conducted through the refrigerant medium circuit 116 to the other blender 214 and is used by the other blender 214 to heat the process air. The process air is conveyed for this purpose in the second operating state through the vaporizer 112 to the other blender 214. For this purpose, according to this embodiment, a dispensing device of the outlet side 322 is provided, which is configured for the the first operating state to drive the ambient air carried through the vaporizer 112 to the ambient air interface of the outlet side 118 and in the second service state, the process air carried through the vaporizer 112 through the other blender 214 to the process air interface of the outlet side 208.

In order to drive the cooling medium in the first service state to the liquefactor 114 and in the second service state to the other liquefactor 214, the switching medium circuit has a switching device 323. For example, the switching device 323 can be realized as a valve commutation.

In the refrigerant medium circuit 116, a compressor 324 is arranged in the direction of the flow to the blenders 114, 214 between the vaporizer 112 and the blenders 114, 214. According to the example of embodiment shown, the refrigerant medium circuit runs from the vaporizer 112 through the compressor 324 to the switching device 323 and in the first service state from the switching device 323 to the blender 114 and in the second service status from the switching device 323 to the other blender 214. In the direction of the flow to the vaporizer 112 is arranged an expansion valve 326 between the blender 114 and the vaporizer 112 and another expansion valve 327 between the other blender 214 and the vaporizer 112 in the refrigerant medium circuit 116. Here a variable throttle valve can also be used (electronic expansion valve).

A process air blower, 328 is arranged in pipes of a process air duct 330, to move the process air between the process air interface of the inlet side 206 and the process air interface of the outlet side 208. An ambient air blower 332 is arranged in the conduits of an ambient air duct 334, to move the surrounding air between the surrounding air interface of the inlet side 110 and the surrounding ambient air interface output 118. A circulation pump 336 is arranged in conduits of a circulation circuit 338, to move the treatment liquid between the circulation interface of the inlet side 106 and the circulation interface of the outlet side 108.

The said first service state of the equipment 102 can be used for a washing process and the second service state can be used for a drying process of an apparatus for treating laundry 100 in the form of a clothes dryer 100. In the dryer Clothes 100 heat is provided on the one hand for the drying process and on the other hand for the washing process. When drying, this is done in the known manner for a dryer: Heat is taken from the wet process air through the vaporizer 112 and "pumped" by the compressor 324 at a higher temperature, whereby heat can be transferred to through the blender 114 back to the process air. When washing, heat is taken from another energy source and transmitted to the washing liquid with a higher temperature. Advantageously, the described heat pump can then have the least possible complexity. This is achieved according to an exemplary embodiment using the structural components that are used where possible to wash and dry.

To control the distribution devices 320, 322, the switching device 323, as well as the transport equipment 324, 328, 332, 336, the control equipment 102 or the apparatus for treating the laundry 100 can be presented with a control equipment, which is configured to controlling the distribution devices 320, 322, the switching device 323, as well as the transport equipment 324, 328, 332, 336 depending on a service state of the apparatus for treating the laundry 100.
