Description
Technical Field
The invention relates to the field of linked control of a range hood and a kitchen range, in particular to a method for preventing the mistaken tripping of the gear of the range hood in a linked system of a range hood.
Background
Range hoods occupy an important position in kitchen appliances. In the cooking process, the range hood is usually matched with a kitchen range for use, the kitchen range is used for processing food, and the range hood is used for sucking and exhausting oil smoke, so that fresh air and clean environment of a kitchen are kept. In order to prevent a user from forgetting to turn on the range hood during cooking and to make the wind power adjustment of the range hood more intelligent, some range hoods adopt a scheme of 'smoke and stove linkage', namely when the user starts a cooker, the range hood is also automatically turned on; when the knob of the cooker is rotated to adjust firepower, the range hood automatically adjusts the suction and exhaust wind power; when the cooker is closed, the range hood is automatically closed or enters a delayed closing state, and the effect of 'wind and fire motion' is realized.
When cooking is finished, if the pointer of the knob of the cooking stove is positioned at the position of small fire, the wind power of the range hood is kept at a low wind shielding position, as shown in fig. 1. The user rotates the pointer of the stove knob clockwise to a flameout position, and the range hood is required to be directly shut down or enter a delayed shutdown state. In the operation process, the pointer of the knob of the cooking utensil firstly passes through the middle fire position and the big fire position and finally reaches the flameout position. According to the control mode of 'smoke stove linkage' of 'wind driven along with fire', the range hood controller can mistake the shutdown process as a normal wind power adjustment. Therefore, the ventilator can be turned off only after the lampblack machine experiences low wind shielding, middle wind shielding and high wind shielding. When the range hood is shut down, a user does not need to additionally adjust the wind power of the range hood, and the control method of 'wind following fire' easily causes the phenomenon of 'mistaken trip' of the range hood, and the phenomenon is more easily caused when the knob rotates slowly. Therefore, aiming at the defects in the prior art, the invention provides a method for preventing the mistaken tripping of the range hood in a linkage system of a range hood, which is necessary to overcome the defects in the prior art.

Fig. 1 is a background art of the present invention and an example of a movement path of a knob of a cooktop in embodiment 1.
FIG. 2 is a flow chart of an implementation of the method for preventing the gear of the range hood from mistakenly jumping in the smoke stove linkage system.
Detailed Description
The invention is further illustrated by reference to the following examples.
Example 1.
As shown in figure 1, the knob type kitchen range has the pointer in the position of small fire, and the wind power of the range hood is kept at a low wind shielding position. If the user carries out flameout operation at the moment, the pointer of the knob of the cooker needs to be rotated clockwise from the small fire position to the flameout position all the time, so that the range hood is shut down or enters a delayed shutdown state. When the knob of the kitchen range sequentially passes through the positions of middle fire and big fire, the range hood can stop running only after wind changes of middle wind shielding and high wind shielding according to the smoke kitchen range linkage scheme of wind moving along with fire. In the shutdown process, the actual trip stop of the fan of the range hood is unnecessary and is not expected by the user. Similarly, the method is not limited to the shutdown process of the cooker, and in the cooking process, the problem of 'mistaken trip' of the range hood exists in any process of adjusting the fire across the gear, such as back-and-forth adjustment of 'small fire' and 'big fire'. Therefore, the invention provides a method for preventing the mistaken tripping of the gear of a range hood in a linkage system of a smoke stove, which is carried out according to the following steps:
s1, the cooker controller carries out AD sampling on the resistance value of the knob of the cooker at the front and back acquisition moments T1 and T2, and the resistance value sampling data at the front moment T1 is recorded as ADC old The resistance value sampling data at the later time T2 is recorded as ADC new . And the cooking appliance controller sends the sampling data to the range hood controller. It should be noted that, in the field of knob cookers, a cooker knob is usually configured as a slide rheostat. The interval between the front and the back acquisition time T1 and T2 is delta T, and the range of the delta T is set to be 0.5-2 seconds in consideration of the operation habit of people on the knob of the stove.
S2, the range hood controller uses the ADC new And ADC old And (5) making a difference and taking an absolute value to obtain the resistance value sampling data variable quantity delta X of the stove knob. It should be noted that, the sliding rheostat of the stove knob has different types, different variation ranges of the resistance values, and equivalently, different variation ranges of the resistance value sampling data. The range of the resistance value sampling data variable quantity delta X of the kitchen range knob is usually 0-100V.
S3, comparing the resistance value sampling data variation quantity delta X of the kitchen range knob with a normal sampling fluctuation value delta by the range hood controller, judging whether the delta X is less than or equal to the delta, and if so, entering S5; otherwise, go to S4. It should be noted that, the range of the normal sampling fluctuation value δ is different according to different models of the cooker controller. Normally the sample fluctuation value δ is in the range of 0 to 3V.
And S4, the range hood controller judges that the knob of the cooker is in a rotating state, and the range hood controller does not send an instruction for adjusting the wind gear of the range hood and maintains the current wind gear of the range hood unchanged. And the smoke ventilator controller selects the new time after the time T2 as the acquisition times T1 and T2, and returns to the step S1. The step effectively avoids the 'false trip' result of the range hood.
And S5, the range hood controller judges that the knob of the range hood is in a static state, and the range hood controller sends out an instruction for adjusting the wind power of the range hood to a corresponding gear according to the current resistance value sampling data of the knob of the range hood. The step realizes the linkage effect of the smoke stove linkage system of 'wind driven by fire'.
The basis for judging the motion state of the knob of the kitchen range by the smoke ventilator controller is as follows:
the stove knob is equivalent to a slide rheostat. Ideal cooker knob static state, constant resistance value of slide rheostat and resistance value sampling data ADC new ＝ADC old ，△X＝∣ADC new －ADC old | =0. When the knob of the stove rotates, the resistance value of the slide rheostat continuously changes, and the resistance value sampling data ADC new ≠ADC old ，△X＝∣ADC new －ADC old | > 0. At the moment, the knob of the cooker is preliminarily judged to be in a rotating state. However, considering that a normal sampling fluctuation value delta exists, when the value of 0 < [ delta ] X is less than or equal to delta, the range hood controller cannot judge whether the ADC variation value in the circuit is generated by the rotation of a knob of a cooker or generated by normal sampling fluctuation. Therefore, only when Δ X > δ, it can be confirmed that the cooker knob is in a rotated state. Otherwise, when the delta X is more than or equal to 0 and less than or equal to delta, the knob of the stove can be considered to be in a static state. Range hood gear anti-false-tripping method in smoke range linkage system of embodimentAnd comparing the magnitude relation between the delta X and the delta to judge whether the knob of the cooker is in a static state or a rotating state.
Further, the rotation state of the knob of the cooker may be classified into two kinds of the step-gear adjusting operation and the adjacent-gear adjusting operation. As shown in fig. 1, the operation of adjusting the range from the "big fire" to the "small fire" refers to the operation from the "extinguishing" to the "middle fire (small fire)", and so on. The purpose of the over-gear adjustment operation is clear, and a user usually completes the operation in a moment. In the process, the faster the knob of the stove rotates, the larger the displacement distance of the sliding sheet of the slide rheostat is, the larger the resistance value change is, and meanwhile, the larger the change of the delta X value is. The step-by-step gear adjustment operation corresponds to the case where Δ X > δ. Because the cross-gear adjusting operation process relates to the change of a plurality of firepower gears, in a smoke stove linkage system, the scheme of 'wind with fire' in the prior art is combined, and the smoke ventilator is easy to generate 'mistaken trip'. In a short time, the load of the fan frequently changes, impact current can be generated on the fan, the power consumption of the fan is increased, and a fan part generates heat, so that the service life of the fan is shortened.
As shown in fig. 1, the adjacent gear adjustment operations refer to back and forth adjustment operations from "flameout" to "big fire", "big fire" to "medium fire", "medium fire" to "small fire", and the like. In the same time, compared with the step-over gear adjustment operation, the adjustment distance of the stove knob of the adjacent gear adjustment operation is short, so the resistance value variation of the slide rheostat is small, namely the variation of the Delta X value is small. The adjacent gear adjusting operation corresponds to the condition that delta X is more than 0 and less than or equal to delta. Because the adjacent gear adjusting operation only involves the change of two firepower gears, the aim of a user is to adjust firepower to the adjacent gear, and the problem of 'mistaken gear jumping' of the range hood cannot occur. The range hood controller can distinguish the adjacent gear adjusting operation without 'error gear jumping' from the over-gear adjusting operation easy to generate 'error gear jumping' according to the judging condition that delta X is more than 0 and less than or equal to delta. The adjacent gear adjusting operation can be classified into the static state of the knob of the cooker.
Aiming at the limitation of a knob type stove control mode in the existing smoke stove linkage scheme, the invention designs a method capable of identifying the movement state of the stove knob according to the existing control module of smoke stove linkage equipment, thereby solving the problem of 'mistaken trip' of a smoke machine in the smoke stove linkage process and ensuring better user experience. The method can also avoid the problem of part loss caused by frequent change of the load of the fan of the range hood, thereby prolonging the service life of the fan.
