Abstract
In a method for operating a vaporizer of a domestic appliance, the vaporizer is filled at least to a predetermined filling level. The vaporizer can be emptied using an emptying arrangement. A time measurement is started, when a filling level falls below the predetermined filling level. A heating system of the vaporizer is switched on, when the filling level falls below the predetermined filling level. The time measurement is stopped, when the heating system has overheated, and a delivery output is calculated during emptying of the vaporizer, from a duration for emptying that is determined by the time measurement.
Claims14
A method for operating a vaporizer of a domestic appliance, said method comprising the steps of:
- (i) filling the vaporizer at least to a predetermined filling level;
- (ii) emptying the vaporizer using an emptying arrangement which includes a pump;
- (iii) starting a time measurement when a filling level falls below the predetermined filling level;
- (iv) switching on a heating system of the vaporizer when the filling level falls below the predetermined filling level;
- (v) stopping the time measurement when the heating system has overheated;
- and
- (vi) calculating a delivery output of the pump during emptying of the vaporizer, from a duration for emptying that is determined by the time measurement, thereby to avoid the pump from running dry.
A vapor processing appliance, comprising:
- a vaporizer including a level detector configured to detect a predetermined filling level, a heating system, and an overheating detector configured to determine when the heating system has overheated;
- a filling arrangement for filling the vaporizer at least to a predetermined filling level;
- an emptying arrangement which includes a pump for emptying the vaporizer;
- a time measuring arrangement responsive, when a filling level falls below the predetermined filling level, thereby causing switching on of the heating system, said time measuring arrangement being configured to stop a time measurement when the heating system has overheated;
- and
- a calculating arrangement configured to at least calculate a delivery output of the pump during emptying of the vaporizer, from a duration for emptying that is determined by the time measurement arrangement, thereby to avoid the pump from running dry.
