The invention relates to an extractor hood and a cleaning control method thereof. The extractor hood comprises an oil-water collecting unit, a first turbidity sensor and a controller, wherein the oil-water collecting unit comprises a first liquid storage tank and is used for collecting oil-water mixed liquid flowing down from the extractor hood; the first turbidity sensor is used for detecting the turbidity of the oil-water mixed liquid in the first liquid storage tank; the controller is in electric signal connection with the first turbidity sensor and is used for acquiring and recording turbidity information of the oil-water mixed liquid in the first liquid storage tank and accumulative operation time information of the extractor hood; and when the accumulative operation time reaches or exceeds a preset accumulative operation time threshold value and the turbidity of the oil-water mixed liquid reaches a preset turbidity threshold value, a cleaning program of the extractor hood is controlled to be started. According to the extractor hood and the cleaning control method thereof, through the combination of the accumulative operation time information and the turbidity information, the oil contamination condition on the corresponding parts in the extractor hood can be reflected more accurately, so that whether the extractor hood needs to be cleaned or not can be accurately judged, and the problem that too much oil contamination is accumulated due to the fact that the optimal cleaning time is missed is avoided.
Description
technical field [0001] The invention relates to the technical field of range hoods, in particular to a range hood and a cleaning control method for the range hood. Background technique [0002] The range hood is a kitchen appliance that purifies the kitchen environment. During long-term use, oil will accumulate inside the range hood and parts (such as impeller, volute, etc.). When a large amount of oil accumulates, it will affect the performance of the range hood. Therefore, it is necessary to clean the range hood and its Oil stains on parts. Most range hoods use automatic cleaning and degreasing methods such as steam washing and heating. The water pump pumps the liquid in the liquid storage container to heat it in the steam generator, and then sprays the liquid heated to a certain temperature directly onto the parts that need to be cleaned. However, due to the limited volume of the container containing water or cleaning liquid, the cleaning effect is limited by the volume...
