FIELD: textile, paper.
SUBSTANCE: household washing machine for dry cleaning comprises a tank, where a perforated drum with clothes rotates, and a closed circuit, which makes it possible for a dissolvent, such as decamethylcyclopentasiloxane, to circulate in an air flow via the drum. The circuit comprises a capacitor, a heater, a fan and at least one has sensor to detect concentration of the dissolvent in air and to transfer according data to the electronic device (38) to control this machine. The gas sensor is an infrared device, which is arranged outside of a closed air circuit and is connected to it so that the gaseous dissolvent may circulate along the optical path, absorbing energy of infrared radiation.
EFFECT: safety of a household washing machine by control of the gaseous dissolvent concentration and timely informing a user, and solving the issue of the gas concentration sensor contamination.
