Method for preventing range hood gear from mistakenly jumping in range hood and kitchen range linkage system

Abstract

The invention provides a method for preventing a range hood gear from mistakenly jumping in a range hood and kitchen range linkage system. In the operation process of the range hood and kitchen rangelinkage system, a kitchen range controller performs AD sampling on the resistance value of a kitchen range knob at a front acquisition moment T1 and a rear acquisition moment T2 at set intervals, andresistance value sampling data is recorded as ADCold and ADCnew. The kitchen range controller sends the sampling data to a range hood controller. The range hood controller subtracts the ADCnew from the ADCold and takes an absolute value to obtain a resistance value sampling data variable quantity delta X of the kitchen range knob. The range hood controller compares the resistance value sampling data variable quantity delta X of the kitchen range knob with the normal sampling fluctuation value delta to judge the motion state of the kitchen range knob. The range hood controller controls a wind power gear according to the motion state of the kitchen range knob. By means of the method, the problem of wrong gear jumping of the range hood in the range hood and kitchen range linkage process is solved, and the user experience is better. The method can also avoid the problem of part loss caused by frequent change of the load of a fan of the range hood, so that the service life of the fan is prolonged.

Description

technical field [0001] The invention relates to the field of linkage control of range hoods and cookers, in particular to a method for preventing false tripping of range hood gears in a range hood linkage system. Background technique [0002] Range hoods occupy an important position in kitchen appliances. In the cooking process, the range hood is usually used in conjunction with the stove. The range hood is responsible for processing food, and the range hood is responsible for sucking and exhausting the oil fume, so as to keep the air in the kitchen fresh and the environment clean. In order to prevent users from forgetting to turn on the range hood while cooking, and to make the wind adjustment of the range hood more intelligent, some range hoods adopt the "stove linkage" scheme, that is, when the user starts the range hood, the range hood is automatically turned on at the same time; When the fire is adjusted by the knob, the range hood automatically adjusts the suction and...

AI Technical Summary

Problems solved by technology

The control method can identify the motion state of the cooker knob, and issue corresponding wind control commands according to the motion state of the cooker knob, so as to solve the problem of "false jumping" of the range hood due to the limitation of the motion track of the cooker knob during the linkage process of the cooker. It has the characteristics of simple judgment logic and no need to add additional control modules
