If a small amount of wash liquor is to be injected through the deflector in the tub, the pump power of the pump can be reduced. If a large amount of wash liquor is to be injected into the tub, the pump power can be increased. As a result, the supply of the laundry care process actually required amount of wash liquor is achieved in the tub and the Einsprühtons the sprayed into the tub wash can be changed.
- the tub at the drain opening comprises a recess for depositing contaminants.
- the technical advantage is achieved that in the recess in the tub contaminants, such as lint, are effectively deposited and thus can be removed from the pumping system. As the contaminants settle in the tub's well, it prevents the contaminants from being pumped through the tubing. This can prevent clogging of the pumped circulation system with impurities.
