Self-cleaning control method for extractor hood wind wheel

Abstract

The invention discloses a self-cleaning control method of an extractor hood wind wheel. The self-cleaning control method includes the steps that S1, a switch key is pressed down, and an extractor hoodstarts to run; S2, a motor for controlling the wind wheel does forward rotation, and whether the time of single continuous forward rotation of the motor reaches a preset value t1 or not is determined, if the time of single continuous forward rotation of the motor reaches the preset value t1, S3 is executed, and otherwise, S6 is executed; S3, the motor stops rotating, when the time that the motorstops rotating reaches a preset value t2, S4 is executed, and otherwise, the motor remains the stopping state; S4, the motor reversely rotates, when the time that the motor reversely rotates reaches apreset value t3, S5 is executed, and otherwise, the motor continues to rotate in the reverse direction; S5, the motor stops rotating again, and when the time that the motor stops rotating again reaches a preset value t4, S6 is executed, and otherwise, the motor continues to keep the stopping state; and S6, the extractor hood stops running. By controlling the forward and reverse rotation of the wind wheel, self-cleaning can be completed, corresponding stop time is last between forward rotation and reverse rotation, and therefore damage to the motor due to direct replacement of forward and reverse rotation is avoided.

Description

technical field [0001] The invention belongs to the technical field of range hoods, and in particular relates to a self-cleaning control method for a range hood wind wheel. Background technique [0002] The range hood has become one of the indispensable kitchen appliances in modern families. During long-term use, the fan wheel of the range hood has a large amount of oil on the surface, which causes the weight of the fan wheel to increase and the dynamic balance to deteriorate, resulting in oil absorption. The noise of the hood becomes louder and the smoking effect is poor. [0003] In order to solve the above problems, range hoods with automatic cleaning functions have appeared on the market. The cleaning methods are nothing more than steam cleaning, hot water cleaning, room temperature water cleaning, and cleaning agent cleaning. Trouble, the range hood cannot be used when cleaning, and the cleaning effect is not ideal. Contents of the invention [0004] In order to sol...
