The invention will be further described below in conjunction with the accompanying drawings：
Embodiment one：
A kind of machine for kitchen use intelligent control method, for machine for kitchen use device, foregoing electric household appliance is provided with master controller, and the timer and counter being connected with master controller, and as shown in Figure 1, Figure 2, the control method includes：Obtain the odor detection value in the environment instantly of smell sensor collection；Obtain the particle concentration detected value in the environment instantly of concentration sensor collection；Gas concentration detected value is calculated according to odor detection value and concentration Testing value；Gas concentration detected value is compared with gas concentration reference value, regulating command is exported according to comparative result；The regulating command includes that the power output of control range hood fan rotation speed change, control heat power of gas burner size variation or control electromagnetic oven changes and conduction time.The present invention gathers the odor detection value and concentration Testing value of kitchen environment using smell sensor and concentration sensor simultaneously, and calculate gas concentration detected value by two gathered datas, gathered data without relying on some sensor merely, smell sensor respectively has its detection feature with concentration sensor, both gathered datas are carried out into reasonable computation, the accuracy of smell sensor and the sensitivity of concentration sensor can be taken into account, the gas concentration detected value deviation for calculating is smaller, closer to actual kitchen environment air quality, compared with gas concentration reference value with the data, the regulating command exported according to comparative result can more reasonably match the working method of machine for kitchen use.
The control method also includes determining whether whether the previous function of home appliance terminates, and previous function terminates, then timer resets and updates；Previous function does not terminate, then continue executing with previous function.The control method also includes determining whether to receive user's operational order, and when operational order is received, then timer resets and updates, and home appliance performs user's operational order；Operational order is not received, then during timer after the first Preset Time, gas concentration detected value is compared with gas concentration reference value, when gas concentration detected value is different from gas concentration reference value, then gas concentration reference value is updated according to gas concentration detected value.It is described to be included according to gas concentration detected value renewal gas concentration reference value, when gas concentration detected value is more than or less than gas concentration reference value, then counter records are once, set point number is reached less than gas concentration reference value when continuous record is more than or continuously records, is then updated the average value of repeated detection as gas concentration reference value.
The control method that the present invention updates including above-mentioned reference value, in the present embodiment, can first carry out that the step of whether previous function of lampblack absorber terminates judged, when previous function terminates, then timer resets and updates；If previous function does not terminate, previous function is continued executing with, until previous function is performed terminating；When judging to terminate when previous function, timer is reset after updating, and determines whether it has received user's operational order, if receiving operational order, timer resets and updates；If not receiving operational order, during timer after the first Preset Time, gas concentration detected value is compared with gas concentration reference value, when gas concentration detected value is different from gas concentration reference value, then gas concentration reference value is updated according to gas concentration detected value.I.e. reference value update be to be carried out in the case of lampblack absorber is idle, if detect lampblack absorber it is functional operation or previous function operation not yet terminate, maintain function execution.
It is that in the present invention, the first Preset Time is 2~6h, preferably 3h in order to ensure that collecting value belongs to the kitchen environment data after the first setting time that timer resets renewal.I.e. previous function is performed and terminated, and starts timing, in 3h, is such as not received by the functional command of user, then after 3h the collection value of smell sensor and concentration sensor just as the data source of renewal reference value；Lampblack absorber is stablized relatively using the kitchen environment collection value after 3h, also closer to actual kitchen environment, set the Preset Time of 3h, it is using the cooking cycle of Chinese style family breakfast, lunch and dinner as foundation, avoid time too short oil smoke concentration unstable, reference value frequent updating also avoids overlong time, it is longer than cooking cycle, causes reference value to update and be excessively passivated.
And for the renewal of reference value, the cycle updating method for repeatedly counting and averaging is used in the present embodiment, i.e., as gas concentration detected value TiMore than or less than gas concentration reference value T0, then counter records once, as continuous record TiMore than or continuous record be less than gas concentration reference value T0Set point number is reached, then by the average value T=SUM (T of repeated detectioni)/n is updated as gas concentration reference value, and reference value after renewal is stored in into memory.In the present embodiment, counts are set as 10 times, as continuous detected value TiDuring more than reference value 10 times, then the average value according to 10 detections is updated as reference value, if in detection process, continuous detected value is more than reference value not to 10 times, detected value is less than reference value next time, then the counting of foregoing detection process Counter resets, and maintains former reference value, if i.e. continuously more than 10 times or continuous less than 10 times, above detected value and counting is not recorded.The present invention can be arranged as required to set point number, such as 5 times, 10 times, 15 inferior arbitrary number of times.For under set point number, ensure that gas concentration detected value is continuously more than or is continuously less than gas concentration reference value, just carry out the set-up mode of reference value renewal, avoid the frequent updating of reference value, surrounding air uneven concentration within a certain period of time is avoided simultaneously, and the situation of reference value is updated according to unilateral environmental quality.The present invention updates to gas concentration reference value makes home appliance have stronger environments match ability, it is adaptable to more Environment spaces.
The present invention calculates gas concentration detected value according to odor detection value and concentration Testing value to be included, after energization timing, when energized between be less than the second Preset Time, then concentration Testing value sampling accounting is 100%；Conduction time is more than or equal to the second Preset Time, then concentration Testing value sampling accounting is 30%-50%.The conduction time is more than or equal to the second Preset Time, and concentration Testing value sampling accounting is preferably 40%.Second Preset Time is 2~5min.Because concentration sensor and smell sensor have different characteristics, concentration sensor detection speed is fast, it is quick on the draw, record is by the instantaneous sampling value of its air-flow, gathered data fluctuation is larger, and smell sensor by electrical conductivity due to realizing that concentration is gathered, therefore certain preheating time is needed, its gathered data just has referential after preheating, thus in conduction time less than in the second Preset Time, sample magnitude all uses concentration Testing value, avoid influenceing its gathered data due to the warm of smell sensor, and then cause not meeting the calculated value of actual environment concentration, usual second Preset Time is set as 2~5min, the present embodiment preferably uses 3min；Conduction time is more than 3min, then adjust concentration Testing value sampling accounting, and concentration Testing value sampling accounting is 40%, the gas concentration detected value T=60% × M+40% × P of calculating under the present embodiment preferably this state（M is smell sensor sampled value, and P is concentration sensor sampled value）The present invention using two data of odor detection value and concentration Testing value as calculate gas concentration detected value, and set specific sampling accounting, make calculating data that there is stronger execution referential, machine for kitchen use answers disposition using the execution state of the calculating data closer to actual kitchen environment, it is to avoid excessively sensitive and machine for kitchen use frequent switching working condition or excessively insensitiveness occur and machine for kitchen use delays to convert the situation of working condition.
The smell sensor and concentration sensor, by the frequency acquisition multi collect of setting, and calculate average value in collection period, using respective average value as the collection period in odor detection value and concentration Testing value.The collection period is 3~8s.In the present embodiment, collection period is used 5 seconds, and the frequency acquisition is 200ms, in the collection period, is gathered N=25 times altogether, calculates 25 average values of collection value as smell sensor sampled value M and concentration sensor sampled value P.Times of collection N in the present embodiment detection cycle is higher or lower than continuously that the relation of the set point number n of reference value is with detected value, the average value of the times of collection N first in detection cycle is used as the detection output valve in the detection cycle, the detection output valve is compared with reference value, higher or lower than reference value, then counter records 1 time, that is n=1, detection output valve in next detection cycle compares with reference value again, if can not be higher than continuously or continuously be less than reference value, the cumulative record n of counter all resets.Collection period of the invention is set as 3~8s, it is to avoid machine for kitchen use excessively frequent switching working condition perceives excessively insensitiveness to oil smoke, as suitable machine for kitchen use to the detecting period of oil smoke.
Embodiment two：
The present embodiment is that such as Fig. 3 in the present embodiment, can be made to determine whether to receive user's operational order first, if receiving operational order, perform user's operational order with the difference of embodiment one；If not receiving operational order, the step of whether previous function of home appliance terminates further judged, when previous function terminates, then timer resets and updates；If previous function does not terminate, previous function is continued executing with, until previous function is performed terminating；When judgement when previous function terminates, timer resets to update and starts timing, during timer after the first Preset Time, gas concentration detected value is compared with gas concentration reference value, when gas concentration detected value is different from gas concentration reference value, then gas concentration reference value is updated according to gas concentration detected value.I.e. reference value update be to be carried out in the case of machine for kitchen use is idle, if detect machine for kitchen use it is functional operation or previous function operation not yet terminate, maintain function execution.The present embodiment will determine whether that receiving user's operational order is positioned over front-end detection, enhance the priority of user's operational order, more focus on control of the user to machine for kitchen use.In the present embodiment, the preferred 2h of first Preset Time, when judgement when previous function terminates, timer is reset after updating beginning timing 2h, i.e. previous function is performed and terminated, and starts timing, in 2h, such as be not received by the functional command of user, then after 2h the collection value of smell sensor and concentration sensor just as the data source of renewal reference value；The setting of 2h makes renewal of the machine for kitchen use to reference value more frequent.
Meanwhile, in the present embodiment, the cycle updating method of average value is only carried out to the continuous detected value more than reference value, and carry out initial value renewal for the continuous detected value less than reference value.I.e. when gas concentration detected value is more than or less than gas concentration reference value, then counter records once, when continuous record reaches set point number more than gas concentration reference value, are then updated the average value of repeated detection as gas concentration reference value；When continuous record reaches set point number less than gas concentration reference value, then gas concentration reference value is updated to initially set reference value T0, i.e. gas concentration reference value replacement.In the present embodiment, the measured value to being continuously less than directly is updated to initially set the reset mode of reference value, reduces the workload of operation of equipment, and home appliance is possessed more stable reference value basis, enhances the stability of system.
Gas concentration detected value is calculated according to odor detection value and concentration Testing value in the present embodiment,Conduction time is more than or equal to after the second Preset Time,Concentration Testing value sampling accounting is 50%,Second Preset Time uses 2min,That is after 2min,Odor detection value and concentration Testing value collection half and half,The present embodiment can shorten collection period for 3s simultaneously,Such as using the frequency acquisition of 200ms,Then in the collection period,Gather 15 times altogether,15 average values of collection value are calculated as smell sensor sampled value M and concentration sensor sampled value P,The present embodiment shortens preheating time and the collection period of smell sensor,The sampling accounting of smell sensor detected value is reduced simultaneously,Improve the sampling accounting to concentration sensor detected value,Make home appliance higher for the sensitivity of kitchen environment oil smoke concentration.
Embodiment three：
The present embodiment is whether such as Fig. 4, the present embodiment terminates without the judgement previous function of home appliance with the difference of embodiment one, and only need to determine whether it has received the operational order of user, when operational order is received, then timer resets and updates, and home appliance performs user's operational order；Operational order is not received, then during timer after the first Preset Time, calculates gas concentration detected value Ti, work as Ti=To, then keep raw-gas concentration reference value To constant；As Ti ≠ To, and gas concentration reference value is updated according to Ti.In the present embodiment, first Preset Time is preferably 6h, the present embodiment by the first Preset Time set it is more long, reduce the renewal frequency of reference value, the accumulated counts to the continuous judgement of detected value are eliminated simultaneously, and directly using the average value in single detection cycle as the foundation for updating reference value, the renewal of reference value will be sensitiveer.Due to the usual custom of Chinese's breakfast, lunch and dinner, behind 6 hours that user receives user's operational order, usual lampblack absorber is in off working state, therefore need not detect whether previous function terminates, and be defaulted as now function and terminated, the scheme of the present embodiment is adapted to afternoon and night quickly updates reference value.Due in the present embodiment, first Preset Time is more long, and it is succinct to update computing, therefore reduced concentrations detected value sampling accounting to 30% is selected, and more using the detected value of smell sensor, the detected value of smell sensor is more reliable and more stable, although slightly slow, but coordinate the simplified calculation of the present embodiment, the update scheme that can be relatively optimized.
Example IV：
The present embodiment is with the difference of embodiment one, such as Fig. 5, the present embodiment calculates gas concentration detected value Ti according to odor detection value and concentration Testing value, gas concentration detected value Ti is compared with gas concentration reference value To, regulating command is exported according to comparative result, the regulating command includes control range hood fan rotation speed change, and control heat power of gas burner size variation, as Ti=To, then maintain the running status of current lampblack absorber and gas-cooker, and as Ti ＞ To, i.e. detected value is more than reference value value, judge that kitchen environment oil smoke concentration is larger, now control range hood fan improves rotating speed, accelerate smoke evacuation；And as Ti ＜ To, i.e. detected value is less than reference value value, judge that kitchen environment is excellent, can now control gas-cooker to lift firepower.Because the present embodiment is the running status of control machine for kitchen use, the utilization of the gas concentration detected value under being therefore applied to machine for kitchen use in working order, same, regulating command is also included as Ti ＞ To, reduce heat power of gas burner, during Ti ＜ To, range hood fan rotating speed etc. is reduced.Running status of the present embodiment using gas concentration detected value control machine for kitchen use equipment in use, gas concentration reference value can also be updated using gas concentration detected value in machine for kitchen use equipment non-operating state simultaneously, with more intelligent application prospect.
Above-mentioned implementation method is only optimal enforcement mode of the invention, it is not whole embodiments of the invention, principle of the invention, those skilled in the art can make various modifications, such as it is higher or lower than continuously the setting of the set point number n of reference value to the times of collection N or detected value in detection cycle, without departing from spirit of the invention, scope defined in claim of the present invention all should be belonged to.
