Description
Technical field
The present invention relates to a kind of air interchanger, specifically a kind of ventilation fan.
Background technique
At present, most ventilation fan structure is single, only be provided with venetian blind in air inlet, the dust in air can not be filtered, have minority ventilation fan to be provided with dust-filtering plate in air inlet, but in use for some time, because dust has got lodged on dust-filtering plate, cause ventilation fan to be ventilated not smooth, ventilation fan is generally arranged on higher position, very inconvenient to the cleaning of dust-filtering plate, therefore this ventilation fan is not popularized.
Summary of the invention
In order to overcome the shortcoming that above-mentioned prior art exists, the object of the present invention is to provide and a kind ofly can carry out again a kind of ventilation fan of automatically cleaning to dust-filtering plate by filtered air.
In order to solve the problem, the present invention is by the following technical solutions: a kind of ventilation fan, comprise housing and fan, it is characterized in that, it also comprises dust-filtering plate, shower head, solenoid valve, pressure transducer and microprocessor, described dust-filtering plate is arranged on the air inlet of ventilation fan, and described shower head is arranged on the front of dust-filtering plate, and the intake pipe of shower head is connected in series a described solenoid valve; Described pressure transducer is arranged on the surface of contact of housing and dust-filtering plate, and pressure transducer is connected with described microprocessor, and the conducting of solenoid valve described in Microprocessor S3C44B0X turns off.
The air inlet of described ventilation fan is also provided with venetian blind, described dust-filtering plate comprises the first dust-filtering plate and the second dust-filtering plate, described first dust-filtering plate is metal filter screen, described second dust-filtering plate is nylon wire, and described venetian blind, the first dust-filtering plate and the second dust-filtering plate inwardly set gradually from the intake grill of ventilation fan; Be provided with four shower heads in the front of described first dust-filtering plate and the second dust-filtering plate, the intake pipe of described shower head is connected in series a full-automatic self-priming pump, and the feed-water end of full-automatic self-priming pump connects a water tank; Be provided with drainage trap on the housing.
The exhaust outlet place of described ventilation fan is provided with electric heating wire.
The invention has the beneficial effects as follows: it arranges dust-filtering plate and filters air, and achieve the automatic cleaning to dust-filtering plate by pressure transducer, shower head and microprocessor, solve because ventilation fan is arranged on the problem that eminence is not easy to clean filter screen; It is also provided with electric heating wire at exhaust outlet, can heat air, can not reduce room temperature when using in the winter time.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is described further:
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, one embodiment of the invention comprise housing 1 and fan 2, dust-filtering plate 3, shower head 4, solenoid valve 5, pressure transducer 6 and microprocessor 7, described dust-filtering plate 3 is arranged on the air inlet of ventilation fan, dust-filtering plate 3 can be that the mode of plug is inserted in housing 1, in housing 1, correspondence is provided with draw-in groove, draw-in groove is made up of the clamp 12 that two are fixed in housing 1, the air inlet of described ventilation fan is also provided with venetian blind 8, described dust-filtering plate 3 comprises the first dust-filtering plate 301 and the second dust-filtering plate 302, described first dust-filtering plate 301 is metal filter screen, described second dust-filtering plate 302 is nylon wire, described venetian blind 8, first dust-filtering plate 301 and the second dust-filtering plate 302 inwardly set gradually from the intake grill of ventilation fan, four shower heads 4 are provided with in the front of described first dust-filtering plate 301 and the second dust-filtering plate 302, the intake pipe of described shower head 4 is connected in series a full-automatic self-priming pump 13, the feed-water end of full-automatic self-priming pump 13 connects a water tank 9, the water that shower head 4 can be made like this to spray is more strong, dust-filtering plate 3 is cleaned more thorough.Described shower head 4 is arranged on the front of dust-filtering plate 3, four shower heads 4 are fixed on four angles place of the dust-filtering plate in housing 1 respectively by metal catheter, four shower heads 4 are all obliquely installed, the angle of it and dust-filtering plate is roughly 45 °-60 °, like this, the shower head 4 being arranged on dust-filtering plate four Angle Position just can rinse dust-filtering plate fully, the intake pipe of shower head 4 is connected in series a described solenoid valve 5, the conducting that microprocessor 7 controls described solenoid valve 5 turns off, the control of microprocessor 7 pairs of solenoid valves 5 is that the ordinary person of art all can realize, it is connected one drive circuit between solenoid valve 5 with microprocessor 7, described pressure transducer 6 is arranged on housing 1 with on the surface of contact of dust-filtering plate 3, and pressure transducer 6 is connected with described microprocessor 7, about the position of microprocessor 7, can be arranged on the outer surface of housing 1, also can be arranged on the internal surface of housing 1.In order to the sewage making shower head 4 clean dust-filtering plate is drained, described housing 1 is provided with drainage trap 10, and the outlet pipe of drainage trap may extend on ground.
Blow out hot blast when using in the winter time to make ventilation fan, the exhaust outlet place of described ventilation fan is provided with electric heating wire 11, and the power on/off of electric heating wire 11 is by independent switch control rule.
During work, after the mesh on dust-filtering plate 3 is blocked by dust, fan 2 is in negative pressure state between fan 2 and dust-filtering plate 3, and now, dust-filtering plate 3 will concave, the pressure transducer 6 be arranged between dust-filtering plate 3 and housing 1 will experience pressure, after pressure reaches setting value, microprocessor 7 Controlling solenoid valve 5 is opened, and shower head 4 starts to clean filter plate 3, after reaching set time, microprocessor 7 Controlling solenoid valve 5 closes.
The above is the preferred embodiment of the present invention, and for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications are also regarded as protection scope of the present invention.
