Figure 4 shows a flow chart of a cleaning process 400 according to a

Exemplary embodiment of a method for carrying out a cleaning process 400 for a cleaning device. The steps of the method as described in FIG. 3 can therefore be carried out within the sub-processes described below.

According to this exemplary embodiment, the cleaning process 400 comprises a fan process 402, a heating process 404, a steam generation process 406, an air washing process 408, a pump-down process 410 and a post-heating process 412, in which the individual

Steps of the procedure are carried out. These sub-processes 402, 404, 406, 408, 410, 412 are carried out one after the other.

After a preparation 414 for the cleaning process 400 by a user, that is

Cleaning device, for example, ready to perform the cleaning process 400. Such preparation 414 includes, for example, placing the items to be cleaned in the

Cleaning device and a selection of a desired cleaning program, such as the cleaning process 400 described in FIG

Preparation 414 for example soiled laundry.

In the fan process 402, the input cleaning stock is processed using the

Process air aerated to remove solids such as dust particles, crumbs or

to remove stones. For this purpose, the process air is conveyed through the drum of the cleaning device at, for example, a maximum speed that can be achieved by the fan.

The heat pump and the feeder are in accordance with this embodiment

Fan process 402 disabled. The solids are separated by ventilation with maximum volume flow.

In the heating process 404, the items to be cleaned are heated using the heat pump and/or the additional heater. The feeder is deactivated. According to this exemplary embodiment, the fan is activated, but it no longer runs at its maximum power, as before in the fan process 402, but at a slightly reduced power, for example at 90% of its power. The heating process 404 ensures that volatile organic compounds (Volatile Organic Compounds; VOCs) from the

Dissolve the items to be cleaned. A separation of odorous substances and pollutants takes place via thermal desorption. For this purpose, the temperature of the items to be cleaned is

Heat pump and auxiliary heating increased to 50°C or more. The higher this temperature, the faster the odorous substances are released from the items to be cleaned. About an adjustment of the holding time and / or the temperature on a degree of pollution, the type of

Laundry and / or responds to energy consumption. For example, high temperatures allow a short treatment time, but high energy consumption is to be expected.

Steam is then generated in the steam generation process 406 using the

Generates additional heating, for example to bind the VOCs released from the items to be cleaned. The heat pump is deactivated and the fan is reduced to a minimum output. The feeder is activated in the steam generation process 406 and delivers the water to the auxiliary heater. In the steam generation process 406, the

Steam is generated in order to remove non-volatile substances from the items to be cleaned using the principle of steam distillation and to improve condensation in the evaporator of the heat pump. The steam is generated by water, such as condensate or distilled water, being conveyed to the additional heater and evaporating there. by means of

process air fan moves the steam onto the laundry.

In the air scrubbing process 408, the vapor is condensed using the heat pump and the VOCs are thus removed from the process air. According to this

In the exemplary embodiment, the fan in the air washing process 408 is activated at maximum power.

The additional heating and the feeding device are deactivated during this time. In other words, the gaseous substances are cleaned from the process air in the air washing process 408 . This happens in an air washer, for example the evaporator

heat pump unit. By condensation and absorption of the gaseous substances at a

The substances are separated from the process air on the fins of the evaporator or on the water droplets adhering to the evaporator. A hydrophilic coating of the evaporator, for example, enables improved wetting and thereby improves the

Absorption. By lowering the fan speed, the flow speed of the process air is reduced and the contact time of the process air to the air washer is extended. Also by a controlled throttle, such as an expansion valve, is the

Evaporation temperature of the refrigerant can also be reduced in order to improve condensation.

In the pump down process 410, the condensed vapor is pumped out and the vapor trapped therein

VOCs are removed. The heat pump, the additional heating and the feed device are deactivated. For example, the fan is activated with a power of 70%. The

Pump down process 410 thus enables removal of the contaminants from the

cleaning device. The substances are with a resulting condensate

Condensate pump transported and promoted with this from the device. This is done, for example, directly in the sewage pipe or alternatively in the as

Condensate container designated collection container, which is emptied after the cleaning process 400 and only optionally rinsed.

The pumping process 410 is only to be regarded as an optional final sub-process. Alternatively, the after-heating process 412 follows the pumping-out process 410. This means that, according to this exemplary embodiment, the user is free to decide whether an end of the

Pumping-out process 410 means a removal 416 of the items to be cleaned or whether the only optional post-heating process 412 follows, in which the items to be cleaned are heated and/or scented again before removal 416 of the items to be cleaned. The heat pump and the feed device are deactivated. However, the additional heating is activated and the fan is also active with a reduced output of, for example, 70%. In other words, the air washer unit is switched off and only the additional heating is activated in order to evaporate the fragrances from a bottle, for example.

In other words, the cleaning process 400 removes

Solids and odors without washing in a heat pump dryer with a

Auxiliary Heater (QPD) and steam production achieved.

A control of actuators that are involved in the cleaning process 400 is described below with reference to FIGS.

Embodiment compared to the other sub-processes 402, 404, 408, 410, 412 changed direction of rotation.

In other words, the motor of the fan is operated at a maximum speed at the beginning of the ventilation phase, ie the fan process 402 several times in alternation. In the

During the heating phase of the heating process 404, the fan is constantly operated with the optimum heating for the heat pump. During the steam generation in the steam generation process 406, the air volume flow of the process air is set to a minimum. This is done, for example, by turning in the opposite direction at the minimum speed. During the

Air washing in the air washing process 408 is the air with the optimum for the heat pump

speed operated. Optionally, the speed is lowered to reduce the effect of the

to improve the air washer. In the pump down phase in the pump down process 410, the

Fan operated at minimum speed. In the optional post-heating process 412, the

Air volume flow increased again to achieve good heating with the heat pump.

For example, the fan signal described with reference to FIG. 1 for controlling the motor of the fan is operated in the preferred direction during sub-processes 402, 404, 408, 410, 412 and in the opposite direction during sub-process 406.

Figure 8 shows a state diagram 800, the operating state based on the

Figures 1 and 2 described additional heating during the cleaning process 400 according to an embodiment.

According to this exemplary embodiment, it is made clear that the additional heating is only deactivated during the air washing process 408 and during the pumping-out process 410 . During the sub-processes 402, 404, 406 and during the post-heating process 412, the additional heating is activated.

In other words, the additional heating is activated as continuously as possible during the sub-processes 402, 404, 406. In order to achieve high temperatures on the additional heater, the air volume flow is minimized. The additional heater advantageously has a PTC base. This means that the power can be independently reduced at high temperatures.

Figure 9 shows a state diagram 900, the operating state based on the

Figures 1 and 2 described condensate pump during the cleaning process according to an embodiment. For example, the condensate pump is permanently controlled with a fixed cycle and thus acts during the entire cleaning process. The

In other words, the condensate pump is activated and deactivated alternately. A fixed cycle is used, which prevents a float switch from being triggered.
