Abstract

The invention relates to the field of small household appliances, in particular to a direct quantitative control method for indoor air purifier filter screen replacement. According to the direct quantitative control method for indoor air purifier filter screen replacement, a mass threshold value is set, and then controlling is conducted through the following steps that after a filtering assembly is installed, the initial weight of the filtering assembly is obtained through a weight sensor, when a filter starts working, a controller obtains the current weight of the filtering assembly by reading the weight sensor in real time, the filtrate weight is obtained by subtracting the initial weight from the current weight, and when the filtrate weight exceeds the mass threshold value, the controller controls an alarming mechanism to give an alarm. According to the method, the weight of particulate matter attached to a filter screen is obtained by monitoring the weight added value of the filtering assembly in real time, when the weight of the attached particulate matter exceeds the mass threshold value, the filter screen needs to be replaced, therefore, quantitative control over filter screen replacement is achieved, the replacement cycle of the filter screen reaches the maximum value while the filtering efficiency is guaranteed, and the method is more beneficial for being used by an ordinary family.

Description

Indoor air cleaner screen replacing direct quantitative control method
Technical field
The present invention relates to small household appliances field, particularly relate to a kind of indoor air cleaner screen replacing quantitative Method processed.
Background technology
China's air pollution is increasingly severe, and at the beginning of 2015 12 months, nearly half territory of China occurs in various degree Haze weather, the average haze number of days in the whole nation has been over the 50 days serious health that have impact on human body, therefore In with serious pollution city, every household all can need indoor air cleaner.
Therefore polluting more serious, the filter screen in the most existing air purifier is the most oversize for service life, Needing often to change, the frequency of existing air purifier replacing filter screen fully relies on user experience and carries out, Not fixing quantity mode, and screen replacing itself is relevant with pollution concentration, every day, pollution concentration became Change very big, be difficult to be determined empirically the screen replacing time;Depurator can be caused to lose without timely replacing Effect, and change too early and can cause waste, it is therefore desirable to a kind of quantitative screen replacing based reminding method.
Summary of the invention
It is directly fixed that the technical problem to be solved is to provide a kind of indoor air cleaner screen replacing In amount control method by the weight gain of the assembly of monitoring filtration in real time obtain having adhered on filter screen Grain thing weight, by this weight with the quality threshold obtained by experiment compared with, when adhere to particulate matter Weight has exceeded quality threshold, illustrates that drainage screen has needed to change, it is achieved that filter screen replacement quantitative Control, while ensureing filtering efficiency, make the replacement cycle of drainage screen reach maximum, advantageously Use in average family.
The present invention is achieved in that a kind of indoor air cleaner screen replacing direct quantitative control method, First arranging quality threshold, be arranged in screen frame by drainage screen, screen frame is arranged on depurator In casing, weight sensor is set, described weight sensor defeated bottom screen frame and between casing Going out end and be connected to controller, described controller controls to connect the alarm mechanism being arranged on outside casing, then presses It is controlled according to following steps:
The filtration assembly that S1, drainage screen and screen frame thereof are constituted is obtained by weight sensor after installing Filter the initial weight of assembly, controller record initial weight;
S2, after filter is started working, controller obtains filtering assembly by reading weight sensor in real time Current weight;
S3, filtrate weight=current weight-initial weight, when filtrate weight exceedes quality threshold, control Device processed controls alarm mechanism and reports to the police.
Described drainage screen includes that coarse filtration net and finly filtration net, described coarse filtration net and finly filtration net each are equipped with Independent screen frame and weight sensor.
In described step S3, alarm mechanism is display lamp.
In described step S3, alarm mechanism is display floater.
In described step S3, alarm mechanism is buzzer.
By monitoring filtration in real time in indoor air cleaner screen replacing direct quantitative control method of the present invention The weight gain of assembly obtains the particulate matter weight adhered on filter screen, by this weight and by real Test the quality threshold obtained to compare, when the particulate matter weight of attachment has exceeded quality threshold, illustrate to filter Net has needed to change, it is achieved that the fixing quantity of filter screen replacement, while ensureing filtering efficiency, The replacement cycle making drainage screen reaches maximum, advantageously uses in average family.
Accompanying drawing explanation
Fig. 1 is to use invention indoor air cleaner screen replacing direct quantitative control method Indoor air cleaner structural representation;
In figure: 1 casing, 2 exhaust blowers, 3 gas exhaust pipings, 4 air inlets, 5 coarse filtration layers, 6 finly filtration Layer, 7 bracing rings, 8 screen frame, 9 weight sensors, 10 alarm mechanisms.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is expanded on further.Should be understood that these embodiments are only used for The present invention is described rather than limits the scope of the present invention.In addition, it is to be understood that reading statement of the present invention Content after, the present invention can be made various changes or modifications by those skilled in the art, these shapes of equal value Formula falls within the application appended claims limited range equally.
Embodiment 1
As it is shown in figure 1, a kind of indoor air cleaner, including casing 1, described casing 1 bottom is for filtering Room, casing 1 top is exhaust chamber, is provided with exhaust blower 2, the top of described casing 1 in described exhaust chamber It is provided with and exports, with exhaust blower 2, the gas exhaust piping 3 being connected;Air inlet 4 is offered bottom described filter chamber, Being provided with drainage screen in filter chamber, described drainage screen includes the coarse filtration layer 5 being sequentially arranged along airflow direction With finly filtration layer 6, described filter chamber inwall is provided with a circle bracing ring 7, described coarse filtration layer 5, thin mistake Filtering layer 6 is arranged on bracing ring 7 by respective screen frame 8, described bracing ring 7 and screen frame 8 Between be provided with weight sensor 9, the outfan of weight sensor 9 is connected to controller, described controller Controlling to connect the alarm mechanism 10 being arranged on outside casing 1, this indoor air cleaner enters in accordance with the following methods Row screen replacing controls:
A kind of indoor air cleaner screen replacing direct quantitative control method, first arranges quality threshold, Drainage screen is arranged in screen frame 8 composition filter assembly, bottom screen frame 8 with casing 1 it Between weight sensor 9 is set, in the present embodiment, described weight sensor 9 is positioned at bracing ring 7 and filter screen Between framework 8, obtain filtering the weight of assembly by weight sensor 9;Then according to following steps are entered Row controls:
