Further, described controller records the power of motor threshold value that described motor drives respective notch, described controller detects described motor and drives the power of motor value of current gear and compare with described power of motor threshold value, triggers described alarm when being less than described power of motor threshold value.
Further, described alarm is buzzer or LED.
Further, also comprise a power panel, described power panel is electrically connected with this motor and controller, after extraneous power supply adjusts by it, for this motor and controller are powered simultaneously.
Further, described controller is also provided with a reset key, to remove current motor driving voltage value and/or the power of motor value record of its monitoring.
Relative to prior art, the air purifier of band filter screen life-span automatic decision of the present utility model, by monitoring control devices motor driven voltage and power of motor, automatically, accurately and effectively can judge the screen pack life-span, the screen pack on timely reminding user to replace filter.
In order to the utility model can be understood more clearly, illustrate below with reference to accompanying drawing and set forth detailed description of the invention of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structure chart of the air purifier of the utility model band filter screen life-span automatic decision.
Fig. 2 is first group of experiment motor speed, power and screen pack relation data figure.
Fig. 3 is second group of experiment motor speed, power and screen pack relation data figure.
Detailed description of the invention
Refer to Fig. 1, the air purifier of band filter screen life-span automatic decision of the present utility model comprises casing 16 and the fan 11, motor 12, filter 13, power panel 14 and the controller 15 that are arranged in casing and alarm (not shown).Wherein, this filter 13 is arranged on the side of casing and just right with this fan 11, using the air inlet as air purifier; This filter 13 there is filter screen.This fan 11 is electrically connected with this motor 12, drives this fan 11 to rotate by this motor 12.This controller 15 is electrically connected with this motor 12 and alarm respectively, its monitoring and record driving voltage and the power of this motor 12, and judges that filter screen on this filter 13 is the need of replacing, as needed to change, then controls to start alarm prompting user thus.This power panel 14 is electrically connected with this motor 12 and controller 15, after extraneous power supply adjusts by it, for this motor 12 and controller 15 are powered simultaneously.
The motor 12 of this air purifier is provided with 5 fixed rotating speeds, to control this fan 11 respectively with five gear runnings.When fan 11 rotates, extraneous air is through filter 13 by the housing 16 of fan suck air clarifier, and this filter 13 completes and purifies air, is then blown out in air by the air outlet 17 above casing again.
Refer to table 1 and table 2, it is the relation data being recorded electric motor mean speed, motor mean power and screen pack windage by many experiments,
When the screen pack of this filter 13 cleans up, when start or gear shift, this controller 15 can be monitored and be recorded driving voltage V and the power P of motor 12 corresponding to the current corresponding gear of this fan 11.Because the sealing of the casing 16 of screen pack and clarifier is fine, when the screen pack blocking of this filter 13, outside air flows through the air velocity just corresponding reduction of screen pack, air-flow reduces the resistance of motor is also just corresponding, and then motor load lightens, further because motor 12 rotating speed is fixing, thus when having served as filter net jam, the driving voltage of the motor that each gear is corresponding and power of motor can decline accordingly.Along with filter screen in use blocks gradually, when start or gear shift, this controller 15 is monitored and is recorded driving voltage V ' and the power of motor P ' of motor corresponding to each gear of fan, and V ' is less than V, and P ' is less than P.By experiment, serve as filter net jam to certain degree, when affecting the normal use of air purifier, record motor driven voltage threshold value Vm and power of motor threshold value Pm, and this motor driven voltage threshold value Vm and power of motor threshold value Pm is recorded in the criterion as the screen pack life-span in this controller 15.
Along with increasing the weight of of filter net jam degree, when start or gear shift, control panel can be monitored and is recorded to motor driven voltage corresponding to each gear of fan and power of motor constantly declines, the power of motor threshold value Pm set is dropped to when control panel monitors the power of motor that motor driven voltage corresponding to each gear of fan drop to motor driven voltage threshold value Vm and/or the correspondence set, at this moment represent that the service life of filter screen terminates, controller 15 controls alarm and sends alarm signal, such as control buzzer rings, or control LED flicker, inform that user must change filter screen.Further, this controller 15 is also provided with a reset key, after user hears and changes filter screen sound, change new filter screen, press corresponding reset key, the performance number when front wheel driving and/or the magnitude of voltage record of the monitoring of this controller 15 are eliminated, and a whole set of filter screen life monitoring system is reworked.
Based on above-mentioned principle, applicant is by two groups of experiments, and have recorded the data relationship of power of motor and screen pack windage, data show, and under identical motor speed, when screen pack is dirty, windage increases, and power of motor value is corresponding to diminish.Table 1 is first group of experimental data, have recorded fan at 1 to 5 gear, motor without screen pack time, use new screen pack time and use old screen pack time power maximum and minimum of a value, in like manner, table 2 is second group of experimental data.Table 3 and table 4 are analysis of experimental data, have recorded in two groups of experiments respectively, motor without screen pack time, use new screen pack time and use old screen pack time power of motor mean value, corresponding motor speed, power of motor and screen pack relation data figure are as Fig. 2 and Fig. 3.
First group, table 1 experiment power of motor and screen pack service condition raw data table
Second group, table 2 experiment power of motor and screen pack service condition raw data table
First group, table 3 experiment power of motor and screen pack service condition data analysis table
First group, table 4 experiment power of motor and screen pack service condition data analysis table
Relative to prior art, the air purifier of band filter screen life-span automatic decision of the present utility model, by controller Real-Time Monitoring motor driven voltage and power of motor, automatically, accurately and effectively can judge the filter screen life-span, the screen pack on timely reminding user to replace filter.
The utility model is not limited to above-mentioned embodiment, if do not depart from spirit and scope of the present utility model to various change of the present utility model or distortion, if these are changed and distortion belongs within claim of the present utility model and equivalent technologies scope, then the utility model is also intended to comprise these changes and distortion.
