Abstract
The utility model provides a filter device of a ventilation system, which comprises a filter unit and a control unit, and is mainly composed of a fan, a primary filter screen, a fine-mesh filter screen and a HEPA high-density filter layer device, wherein the primary filter screen is installed at the back of an air inlet fan, the fine-mesh filter screen is further arranged at the back of the primary filter screen, the HEPA high-density filter layer is arranged on a port of an indoor air inlet, a sealing baffle plate is arranged at the back of the HEPA high-density filter layer, the fan has two purposes, and can suck air positively and reversely. When in normal use, the sealing baffle plate is opened, and is closed by the control unit when needing to clean an inlet duct, and the fan is controlled to suck reversely for cleaning dust accumulated on the filter screen. The filter device can randomly be carried out with backwash after arranging the two-purpose fan in consideration that a ventilating filter system can accumulate dust after use for a long term, and can generate a certain affect to indoor environment, and a filter system is complicated for people to detach and clean.
Description
Technical field
The utility model relates to a kind of ventilation unit, especially a kind of noise reduction ventilation unit.
Background technology
In China, room ventilation is familiar with significantly, and has been put on agenda by country.Each real estate " giant " is openly claimed in calendar year 2001 " Bo'ao building forum ": should be the competition of indoor environment future, and indoor environment most important be exactly air quality! This respect Shanghai, Beijing are the forerunner, and example is too numerous to enumerate.VMC is installed by existing 90% above family at European the seventies, the Chinese of 21st century, behind diseases such as SARS, epidemic meningitis popular, more and more begin to pay close attention to health, pay close attention to environmental protection, pay close attention to air quality, France's blue house product is " nature, health idea " come true and to incorporate indoor brand---i.e. pure and fresh at indoor same enjoyment the Nature, its two combination certainly will bring up the brand-new platform of desirable concept of residence.The use of central ventilation system not only can replace the screen window of family, makes that building resident family more attractive in appearance, high-rise is safer, to prevent that the house from making moist mouldy, thereby guarantees the life-span of building.
In order constantly to have a breath of fresh air, for indoor environment and household's health, we need good family expenses ventilating system to improve indoor environment.
Because the ventilation unit major function is to promote circulation of air, so the air intake quality of ventilation unit has determined the quality of room air, the filter of ventilation unit then plays an important role.
Summary of the invention
At the problems referred to above, the utility model provides a kind of filter of ventilating system.
A kind of filter of ventilating system, comprise filter element and control module, it is characterized in that mainly by blower fan, elementary filter screen, detailed catalogue filter screen and HEPA high density filter bed device are formed, elementary filter screen is installed on the rear of air inlet blower fan, also be provided with the detailed catalogue filter screen thereafter, be provided with HEPA high density filter layer at the indoor air inlet port, also be provided with a sealing baffle thereafter, its blower fan is a Dual-purpose fan, can positive and negative exhausting, during normal the use, sealing baffle is in open mode, when needing to clean intake stack, by control module sealing baffle is closed, the control blower fan carries out back suction, the dust that accumulates on the filter screen can be cleaned out.
Remarkable result of the present utility model is to consider that the phenomenon of dirt accumulation can appear in the filtration system of ventilation after permanent the use, indoor environment is affected, to carry out disassembly, cleaning also be suitable trouble and manually carry out filtration system, after being provided with Dual-purpose fan, just can instead at any time clean, very easy to use.
Description of drawings
Figure is the filter schematic diagram of ventilating system
Wherein: 1, sealing baffle; 2, HEPA high density filter layer; 3, the detailed catalogue filter screen; 4, elementary filter screen; 5, blower fan.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further: this device is mainly by blower fan 5, elementary filter screen 4, detailed catalogue filter screen 3 and HEPA high density filter layer 2 device are formed, elementary filter screen 4 is installed on the rear of air inlet blower fan 5, also be provided with detailed catalogue filter screen 3 thereafter, be provided with HEPA high density filter layer 2 at the indoor air inlet port, also be provided with a sealing baffle 1 thereafter, its blower fan 5 is a Dual-purpose fan, can positive and negative exhausting, during normal the use, sealing baffle 1 is in open mode, when needing to clean intake stack, by control module sealing baffle 1 is closed, control blower fan 5 carries out back suction, the dust that accumulates on the filter screen can be cleaned out.
The utility model is applied in family or the industrial ventilation system, consider that the phenomenon of dirt accumulation can appear in the filtration system of ventilation after permanent the use, indoor environment is affected, to carry out disassembly, cleaning also be suitable trouble and manually carry out filtration system, after being provided with Dual-purpose fan, just can instead at any time clean, very easy to use, can save 20% filter screen cleaning cost.
