Document Type and Number:
WIPO Patent Application WO/2019/075991
Kind Code:
A1
Abstract:
A range hood, a range hood cleaning device and a control method therefor. The cleaning device comprises: a water pump (100), the water pump (100) being used for extracting a cleaning fluid when the water pump is turned on; a heating assembly (200), the heating assembly (200) being connected to the water pump (100); a temperature sensor (300), the temperature sensor (300) being provided corresponding to the heating assembly (200) and used for detecting the temperature of the heating assembly (200); a spray pipe (400), the spray pipe (400) being connected to the heating assembly (200); and a control module (500), the control module (500) being separately connected to the water pump (100), the heating assembly (200), and the temperature sensor (300). The control module (500) controls the heating assembly (200) to heat when a range hood starts a cleaning process, and after the temperature of the heating assembly (200) reaches a first preset temperature for the first time, controls the water pump (100) to be on for a first preset duration and off for a second preset duration during each cleaning period; when the water pump (100) is turned on, the cleaning fluid is extracted into the heating assembly (200) for heating so as to generate a high-temperature and high-pressure vapor mixture, and the vapor mixture is sprayed out from the spray pipe (400) to clean the range hood. The cleaning device can improve the effect of cleaning a range hood.
