Method for regulating a flow of water during a steam generation phase of a laundry drying machine and laundry drying machine

The method involves evaluating a flow rate of water introduced in a vapor generator (12) by measuring parameters of a vapor generation phase using a regulation thermostat. The water flow rate of the vapor generation phase is adjusted based on the evaluation result using a microcontroller. The vapor generator is connected to a water supply source (19). The supply source is connected to a pump (20) for supplying water to the vapor generator. The generator has a heating unit (18) for heating and evaporating the water. An independent claim is also included for a clothes drying machine for implementing a water flow rate regulating method.
