The shutter protects the ventilator and the rotating blades from foreign substances when the ventilator starts, prevents backward blowing from the outside when the ventilator is closed (lung), and prevents inflow of pests, rats, birds, foreign matter, fine dusts.

It also protects and maintains the fan from ultraviolet rays and external impacts.

If the wind pressure of the ventilator falls below the reference value due to the service life of the ventilator, defects, or the use environment, the opening angle of the shutter is reduced or not opened. As a result, the wind pressure for ventilator installation is decreased, The lungs (closed) are not allowed to enter the backwind, pests, rats, birds, foreign matter, fine dust, etc. can enter.

When the oil or harmful substance is adhered to the shutter by the ventilation fan ventilation, there is a problem that the ventilation fan may fail because the shutter is not opened even when the wind pressure of the ventilator is normal.

Fig. The shutter cleaner 220 and the electromagnet 230 according to the embodiment of the present invention.

Referring to FIGS. 1 to 3, it can be seen that the present invention includes the attachment plate 100, the frame 200, the shutter blade 10, the guide 20, and the shaft 30 formed in the ventilator shutter.

The attachment plate 100 is not limited in its shape and can be configured to correspond to the ventilator structure, but is shown in a rectangular shape in the figure for the sake of concretely explaining the structure.

The frame 200 is coupled to the attachment plate 100 and may be formed in a square pillar shape.

The shutter blade 10 may be formed by a structure of a general ventilator shutter blade 10, and may be opened or closed by air volume and wind pressure of the ventilator.

In addition, the frame 200 may be structured such that it is pivoted through the shaft 30 from below to open in a semicircle.

The guide 20 is based on the lever principle and is involved in the opening and closing of the shutter blade 10.

The guide 20 can be configured to rotate the shutter blade 10 in a structure in which it is coupled to the shutter blade 10 by the shaft 30.

The shaft 30 may be provided to correspond to the number of the shutter blades 10.

Further, the guide 20 may include a coupling hole (not shown) for passing the shaft 30 therethrough.

If the wind pressure of the ventilator falls below the reference value due to the service life of the ventilator, defects, or the use environment, the opening angle of the shutter is reduced or not opened. As a result, the wind pressure for the ventilator installation is decreased and the ventilation effect is decreased. It causes the adverse winds or the inflow of pests, rats, birds, and foreign matter.

When the oil or harmful substances are adhered to the shutter by the ventilator ventilation, the shutter is not opened even if the wind pressure of the ventilator is normal, which causes not only ineffectiveness but also causes the failure of the ventilator.

The principle of the lever is that when a load W is determined at point B of a stick supported at a point C and a force P is applied to another point A to balance the stick, X (length AC) = W x (length BC) '. The magnitude of the force acting on both ends of the lever is multiplied by the length to the fulcrum, respectively. So if the AC is longer than BC, you can support or lift the heavy thing with a small force. This law is said to have been discovered by Archimedes and is widely applied to pumps and spanners.

The guide 20 serving as a lever can control the shutter blade 10 to be opened by a certain angle according to its weight and length.

That is, when a certain amount of wind and air pressure are applied regardless of wind volume, wind pressure, and the like, a plurality of shutter blades can be opened and closed by the operation of one shutter blade.

For reference, the shutter blade 10 and the guide 20 may be made of weather resistant resin ASA (Acrylic Styrene Acrylonitrile).

Specifically, ABS (Acrylonitrile-Butadiene-styrene) resin is widely used for home appliances and office equipment because of its excellent properties such as molding processability, chemical resistance and impact resistance. However, the ABS resin is disadvantageous in that when it comes in contact with oxygen, ozone, ultraviolet rays or the like in the air, discoloration or deterioration of physical properties occurs, so that there is a limit to use in an electronic product or an outdoor use product in which weather resistance is required.

In order to solve this problem, a method of coating a paint having excellent weather resistance on the surface of a molded article or adding a light stabilizer has been adopted. However, since there is a limit of long-term weatherability and a cost increase due to secondary processing, A fundamental solution is required. As a result of these demands, ASA, ACS, AES and so on are available as weather resistant resins.

ASA (Acrylic Styrene Acrylonitrile), which is a weather resistant resin, has excellent physical properties such as general ABS and excellent weatherability. It is a resin that can be used as an exterior material because it maintains its stable physical properties over the long term.

Generally, an ABS resin composed of butadiene, styrene monomer, and acrylonitrile is excellent in impact resistance and processability and has excellent mechanical strength and is widely used for a variety of applications such as electric and electronic housings, automobile interior and exterior materials, and the like have.

However, the ABS resin is a polybutadiene rubber which is used for impact reinforcement and has an alpha-hydrogen dissociation energy of 39 ㎉ / mol of a double bond and is easily dissociated into low-energy light of wavelengths of 700 nm or less. There is a problem in that the physical properties thereof are drastically lowered and discoloration occurs as a result of the attack.

On the other hand, ASA resin uses acrylic rubber which does not have double bond instead of butadiene, and dissociation energy of hydrogen is about 90 ㎉ / mol, light of wavelength energy below 300nm (among the sun rays of the ground (Not present).

That is, since it has a molecular structure which is basically hard to cause weathering deterioration, the weatherability, which is the greatest defect of the ABS resin, is remarkably improved, and the change of the resin characteristic and the appearance of the molded article are remarkably smaller than those of the ABS resin in outdoor use over a long period of time.

Because of this, ASA resins are used extensively in applications where exposed to external climates.

According to the above description, the guide 20 uses the principle of the lever to open the shutter blade 10 at a certain angle with the wind pressure of the ventilator.

For reference, the shutter blade 10 starts to open by 30% due to wind pressure and wind pressure of 25% of the ventilation fan, and the remaining 70% is completely opened by the guide 20. As a result, The shutter blade 10 may be opened smoothly by adding the leverage principle to the constant wind pressure and the weight of the guide 20 even when falling below the reference value.

It is preferable that the fully open angle of the shutter blade 10 is maintained at 68 degrees when the blower is started.

If the shutter blade 10 is opened at an angle of 68 degrees or more, ventilation may be generated on the upper surface of the shutter blade 10 to generate noise.
