Abstract

The disclosure relates to the technical field of laundry apparatus manufacturing, and discloses a space textile cleaning equipment and a cleaning method, comprising a washing unit consisting of: a housing, in which a fixing plate for paving the fabric and a fixing clip for clamping and fixing the paved fabric are arranged; and a scraper corresponding to the fabric, which can move along the length direction or the width direction of the fixing plate, and is also provided with an atomizing nozzle for spraying detergent, with the outlet of the atomizing nozzle corresponds to the fabric. The disclosure overcomes the problems of large water consumption and difficult dewatering in microgravity environment in the existing washing method, solves the problem that clothes in microgravity environment can only be replaced by disposable method at present, meets the requirements of long-term long-range manned flight in the future, reduces the upward load, and is of great significance to textile cleaning in microgravity environment.
