Typically, in conventional laundry treatment devices, especially in conventional laundry treatment devices with a heat pump, an evaporator of a heat exchange mechanism is provided to reduce the humidity of the circulating air during the drying process. During the drying process, impurities in the laundry, such as fluff, can be contained in the circulating air and can accumulate on the evaporator, thereby reducing the efficiency of the heat exchange mechanism and the drying process of the laundry.

[0006] Thus, the second water level may define a predetermined volume of condensed water in the collection container so as to provide a predetermined volume of condensed water to the at least one fluid diffuser during the cleaning phase. Thus, an efficient flushing process with a predetermined volume may be achieved. The predetermined volume may be an optimal volume of condensed water, which enables impurities, in particular fluff, to be effectively flushed from the evaporator into the collection container.
[0007] The pump can be arranged at the bottom of the collecting container.

[0032] Therefore, the evaporator, in particular the condenser, can be effectively flushed.The second water level may be a water level into which the impeller of the pump is fully immersed during the cleaning phase to achieve a predetermined volume flow rate.
[0033] According to a second aspect, the present disclosure relates to a control method for a clothing treatment device, wherein the clothing treatment device includes a drying chamber for drying clothing and an air passage, the air passage being connected to the drying chamber via an air inlet and an air outlet, the air inlet being configured to be able to supply air from the drying chamber into the air passage, and the air outlet being configured to be able to supply air from the air passage back into the drying chamber, wherein an evaporator is arranged downstream of the air inlet in the air passage, the evaporator being configured to be able to cool the air provided by the air inlet during cooling of the air to condense water at the evaporator, and impurities in the air, in particular fluff, being deposited at the evaporator, wherein the clothing treatment device includes a collecting container arranged below the evaporator, the collecting container being configured to be able to collect condensed water of the evaporator, and the collecting container being fluidly connected to at least one fluid diffuser arranged above the evaporator via a pumping line. , wherein a pump-out line is fluidly connected to a collecting container to remove water from the collecting container, wherein the laundry treatment device comprises a controller and a pump, wherein a water level sensor connected to the controller is arranged inside the collecting container, and the method comprises: activating the pump by the controller during a cleaning phase to pump the water collected in the collecting container into the at least one fluid diffuser through the pumping line; supplying the pumped water to the evaporator through the at least one fluid diffuser during a cleaning phase to flush impurities, in particular fluff, from the evaporator into the collecting container; detecting the water level of the water in the collecting container by the water level sensor; activating the pump by the controller during a collecting phase prior to the cleaning phase to pump water out of the laundry treatment device through the pump-out line when the water level sensor detects a first water level; and deactivating the pump by the controller during the collecting phase when a second water level lower than the first water level is reached.
[0034] Thus, the second water level can define a predetermined volume of condensed water in the collection container so that a predetermined volume of condensed water is provided to the at least one fluid diffuser during the cleaning phase. Thus, an efficient flushing process with a predetermined volume can be achieved. The predetermined volume can be an optimal volume of condensed water, which enables impurities, in particular fluff, to be efficiently flushed from the evaporator into the collection container.
