A method for measuring the humidity of a laundry mass contained in a laundry treatment chamber of a laundry appliance. The method includes: providing a capacitor in the laundry appliance, said capacitor having, as part of the capacitor dielectric, the laundry mass; measuring a capacitance of said capacitor by means of an electronic circuitry electrically supplied by a supply voltage and a reference voltage. Providing a capacitor comprises: providing in the laundry appliance at least one conductive plate which forms a plate of said capacitor, and exploiting, as a second plate of said capacitor, routing lines distributing inside the laundry drying appliance said reference voltage.

A clothes dryer apparatus and system that reduces the buildup of electric charges within a dryer drum by introducing ions. The system monitors the voltage within the drum by taking measurements on voltage sensor assembly. The sensor assembly obtains a voltage when two areas of a fabric, or two separate items of the clothing, contact the sensor. If a threshold voltage is obtained, an ion generator introduces cations and anions into the drum of the dryer to neutralize the static charge of the clothing. The reduction of static electricity increases efficiency as the clothing items do not stick together which permits better heat flow and increases safety by reducing the amount of electrical charge within the drum.

A control method of a laundry treatment apparatus is disclosed which includes a course setting procedure receiving a control command including RPM control data of an impeller, RPM control data of a compressor or opening degree control data of an expansion valve, a hot air supply procedure for supplying heated air to a drum through control of the impeller, compressor and expansion valve, a temperature measurement procedure measuring temperature of air introduced into the drum during execution of the hot air supply procedure, a first control procedure for controlling the impeller, compressor and expansion valve based on the control command when the measured temperature is equal to or higher than a reference temperature, and a second control procedure controlling the impeller, compressor and expansion valve based on a control command different from the control command set in the course setting procedure when the measured temperature is lower than the reference temperature.
