Abstract

The present invention provides an air purifier having an air purifier accommodating a filter in the rear of a fan so that wind or air generated from the fan can be cleaned, thereby enabling an air cleaner to be performed at a very low cost through a fan .

Description

[0001] The present invention relates to a fan air purifying apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifier for an electric fan, and more particularly, to an air purifier for an electric fan having a filter paper therein so that the air purifier can be operated at a very low cost through a fan will be.

Generally, an electric fan is a device that generates wind to dissipate heat generated in a person's body and is composed of a motor and a fan.

The conventional fan has a main body that is seated on a floor surface and has an operating portion for operating a power source and an air volume, a stand vertically erected on the upper surface of the main body, And a shielding net attached to the front end of the driving body for blocking contact between the fan and the rotating fan. When the fan is rotated, the outside air flows through the rear of the shielding net, It is a structure that generates wind.

However, dust or foreign matter may be contained in the air flowing into the conventional fan, so that the air passing through the fan, that is, the blowing air, is contaminated, which has a bad influence on the user's respiratory and skin.

In order to solve such a problem, a technical document such as a domestic registered patent No. 10-0669974 has been disclosed.

In the conventional air cleaning filter equipped with an electric fan, a horseshoe-like support member having front and rear faces opened behind the protective net of the fan, and an element made up of a plurality of protrusions and a film air passage are housed in the support member. And the member is adhered to the rear of the protective net of the fan.

However, there is a problem that a conventional air cleaning filter attached to an electric fan is adhered to the rear of a fan, and therefore it is very inconvenient to remove the adhesive portion when the element is replaced after a long period of use.

In addition, the conventional technique has not been able to purify the contaminated air flowing through the cut-out portion formed in the lower part of the horseshoe shape, thereby greatly reducing the air purification rate.

In addition, in the related art, if the element is partially contaminated, the whole formed element must be replaced, so that the maintenance cost is unnecessarily increased, and the element attached to the support member is peeled off with an adhesive such as a bond This is very inconvenient, so that there is a problem that the support member must be exchanged with the cylinder.

The present invention has been made in order to solve the problems of the related art as described above, and it is an object of the present invention to provide an air purifier in which a filter is housed in a rear of a fan so that wind or air generated in the fan can be cleaned, The air cleaner can be operated at a very low cost through an electric fan disposed in the air cleaner.

According to another aspect of the present invention, there is provided an air purifying apparatus for an air cleaner installed in a rear portion of a safety net provided in a fan and a motor case for purifying air introduced from the outside, A ring-shaped inner frame provided inside the outer frame and seated on the motor case with a diameter smaller than the diameter of the outer frame; and a plurality of links connecting the outer frame and the inner frame A donut-shaped main frame part comprising a frame, a filter housing part where the connection frame is divided into sections, and a mounting cut-out part which is cut out through the outer frame and the inner frame to allow the motor case to pass therethrough; A filter unit having the same shape as that of the filter housing unit so that the air contained in the filter housing unit and purified from the outside can be purified; And a donut-shaped filter fixing part formed in a mesh-like shape so as to block the deviation of the filter part and to introduce outside air into the rear of the main frame part.

Like filter seating parts extending to both sides are formed on the front part of the connection frame so that the filter part is prevented from being separated forwardly and the filter seat parts are formed with elongated hole- do.

And a plurality of frame inflow holes formed on the inner surface of the outer frame and the inner frame, the inflow holes being cut out to a predetermined width so that the air introduced into the outer frame and the inner frame may flow in the lateral direction.

The filter fixing part is formed in the same shape as the outer frame and the inner frame, and has a filter fixing frame with an opened inner surface, a filter fixing mesh network connected to the inner surface of the filter fixing frame, .

And a plurality of filter fixing protrusions protruded in one direction so as to insert the outer surface of the filter fixing portion is provided on one surface of the outer frame and the inner frame.

Wherein the filter seat has a plurality of catches to be inserted into the safety net to fix the air cleaner; The locking pawl includes a locking protrusion formed on the front side of the locking pawl, a pillar-shaped elastic pillar extending on the rear side of the locking pawl, a locking body attached to one surface of the elastic pillar, And a latching rail protrusion.

And an inner side surface of the outer frame is provided with a band stopper bent in an "L" shape so that a hooking band wound on the safety net is caught.

 And a flat elongated plate extending forward to be in close contact with the rear of the curved safety net is formed on the front surface of the outer frame.

The main frame part is provided with a curved main frame formed in a state in which the outer frame is moved forward of the inner frame so as to be in close contact with an outer surface of the safety net curved backward.

As described above, the effect of the air cleaner for an electric fan according to the present invention is as follows.

First, since the air purifier is installed in the rear of the fan so that the wind or air generated in the fan can be cleaned, the air purifier can be operated at a very low price through the fan disposed in the home in general,

Secondly, by piercing a plurality of air inflow holes in the frame portion of the air purifying device, it is possible to greatly increase the amount of air inflow by reducing the amount of air blocked by the frame,

Thirdly, by providing a plurality of hooks on the front face of the frame part, it is possible to fasten the air purifying device to the safety net very conveniently only by the action of the user pushing forward,

Fourthly, by forming a band-stopping portion bent in an "L" shape on the inner surface of the frame portion, it is possible to fasten the main frame portion and the safety net by hooking the other side portion of the rubber band, There is an effect that the air purification apparatus can be fastened to the safety net very conveniently.
