Background technique

Because the seal of dwelling house is become better and better, people's life becomes more comfortable.The effective energy-conservation etc. of the enhancing of effect of heat insulation and air conditioner makes the airtight advantage of dwelling house more obvious, but such dwelling house also brings a lot of problems simultaneously: air is completely cut off relatively, air quality worse and worse, by containing a lot of insalubrious materials in structural material, ornament material, electric equipment, daily or the muddy air that office appliance, smog, human body or pet metabolism etc. are distributed, in the environment that the muddy gas of being everlasting can't be got rid of, live, bring a lot of negative effects to human body.

Ventilation fan is that family, office and public place etc. are essential as a kind of circulation device for air that is usually used in the indoor air discharge.The tradition ventilation fan adopts the switch manual control, and automaticity is low, uses inconvenient.The employing sensor of usefulness is responded to air quality automatically at present, the work of via controller control ventilation fan, as the patent No. be 200820082311.7, disclosed self-controlled type ventilation fan such as 96229599.X, though realized the automation of ventilation work, its controller is fixed air quality information processing formula, can only be applicable to stationary applica-tions, can't satisfy different occasions or different individual requirement to air quality, the hommization degree is low, easily causes ventilation fan not work for a long time, causes air quality relatively poor; Or the long-time non-productive work of ventilation fan, wasting energy, working life is short.

Summary of the invention

In order to overcome shortcoming of the prior art, the utility model provides the air quality intelligent inductive air exchange fan of a kind of hommization, automaticity height, energy-saving and cost-reducing, long service life, this ventilation fan can under the different occasions or the individual to air under different the requirement, open and close according to IAQ control ventilation fan, improve IAQ in real time, guarantee that people live, work comfortable.

In order to reach above purpose, the technical solution adopted in the utility model is: a kind of air quality intelligent inductive air exchange fan comprises ventilation system and control system, described ventilation system comprises motor, wind wheel, the air channel cover plate that is installed in successively in the spiral case, and the anterior air port of spiral case is equipped with face shield; Described control system comprises air quality broad-spectrum inductive probe, multistage fork shift switch, microprocessor, air quality broad-spectrum inductive probe is connected with microprocessor respectively with multistage fork shift switch, described microprocessor and multistage fork shift switch are arranged at the spiral case afterbody, air quality broad-spectrum inductive probe is located on the cover plate of air channel or on the spiral case housing, multistage fork shift switch is regulated the many groups air quality setting value in the microprocessor, air quality broad-spectrum inductive probe provides the air quality induced signal to microprocessor, and microprocessor opens and closes air quality induced signal and the contrast of air quality setting value through relay control ventilation system.

The utility model adopts air quality broad-spectrum inductive probe to be connected with microprocessor controller, dirty gas in the sensing chamber in real time, smog etc., and by the contrast that microprocessor controller is made relative pollution to indoor air judge and output to the keying signal of ventilation system, realize the variable intelligent control of airtight relatively IAQ, when ventilation fan is installed by the different requirements of use occasion or human body to air quality, regulate the multistage fork shift switch of spiral case afterbody in advance and set the many group setting value of the overhead gas phase of microprocessor polluting, adapt to different occasions or satisfy the different requirements of human body air quality, avoid the traditional intelligence switch to be used in the long-time non-productive work of ventilation system under the different occasions or do not work for a long time, prolonged the working life of ventilation system, improved working efficiency, energy-saving and cost-reducing, the automaticity height.

Fig. 2 is the control principle figure of the utility model control system.

Among the figure: spiral case 1, air channel cover plate 2, air quality broad-spectrum inductive probe 3, microprocessor 4, multistage fork shift switch 5.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1, air quality intelligent inductive air exchange fan shown in 2, comprise spiral case 1, motor, wind wheel, air channel cover plate 2, motor is installed in the spiral case 1 successively, wind wheel, air channel cover plate 2, be provided with microprocessor 4 and multistage fork shift switch 5 in the Direct box of spiral case 1 afterbody, air channel cover plate 2 or spiral case 1 housing are provided with air quality broad-spectrum inductive probe 3, multistage fork shift switch 5 is connected with microprocessor 4 respectively with the general inductive probe 3 of air quality light, after the air quality broad-spectrum inductive probe 3 detecting air quality, with detected signal input microprocessor 4, microprocessor 4 compares the relative soiling value of setting on air quality induced signal and the microprocessor 4 of air, contrast is judged after the keying of relay control ventilation system realizes the intelligent control to IAQ.According to the different requirements of different use occasions or human body, regulate the environmental variance reduced values of setting in the microprocessors 4 by multistage fork shift switch 5 and be the relative soiling value of air during installation air quality.

When air quality intelligent inductive air exchange fan was installed, different use occasions of foundation or human body were regulated the processing environment variable reduced value that multistage fork shift switch 5 is set in the microprocessors 4 to the different requirements of air quality; After the installation, 3 pairs of air qualities of air quality broad-spectrum inductive probe are surveyed and with the signal input microprocessor of surveying 4, microprocessor 4 compares according to the gear setting value that multistage group of position switch 5 is allocated to, and the result after the contrast is through the keying of relay control ventilation system.Air quality intelligent inductive air exchange fan ABAP Adapter switch, power switch is realized the positive closing ventilation fan function through relay.

Embodiment: as the air quality broad-spectrum inductive probe 2 of ventilation fan for surveying CO content, before ventilation fan is installed, regulate multistage fork shift switch set microprocessor to three groups of setting values of atmospheric pollution contrast a little less than shelves 0.5PPM, middle-grade 0.1PPM, prime time 0.05PPM.When being used for good occasion of air quality or human body air quality is required when high, after multistage fork shift switch 5 is allocated to prime time 0.05PPM ventilation fan is installed, CO in air quality broad-spectrum inductive probe 2 detecting airs, with detected signal input microprocessor 4 and prime time 0.05PPM contrast, when CO content is greater than or equal to prime time 0.05PPM in the air, microprocessor 4 is opened the ventilation fan ventilation through relay, when CO content in the air is reduced to below the 0.05PPM, microprocessor 4 is through the cut-off ventilation fan, and the keying of little processing 4 control ventilation fans is provided with delay function; If when CO content was lower than prime time 0.05PPM in the air, ventilation fan was not worked.If when being used for the serious relatively occasion of atmospheric pollutions such as smoking room or work-yard, multistage fork shift switch 5 can be selected behind the middle-grade or weak shelves ventilation fan to be installed again.
