Description
The present invention relates to a pipe-type air filter. More specifically, air is introduced into a hollow tube corresponding to the inside of a pipe through which air flows (including pipes of all cylinders, Type air filter capable of maximizing the filter efficiency even in a narrow space inside the pipe by inserting the filter paper into the pipe so that the filter paper can be directly filtered in the flowing direction.
In the pipe-type air filter, generally, the air filter is installed at one side of a pipe (hereinafter referred to as a "pipe") such as various pipes, tubes, ducts and pipes The air filter is capable of filtering various dusts, germs and fine dust contained in the flowing air. As disclosed in Korean Patent Publication No. 82644 (published on Dec. 5, 1998), a polygon The upper and lower cases have a substantially hexahedron shape between the cylindrical inlet pipe and the cylindrical outlet pipe, and air having a zigzag filter paper inserted in the inside of the rectangular frame inside the upper and the lower case is provided between the cylindrical inlet pipe and the cylindrical outlet pipe by folding the filter paper zigzag from one side to the opposite side. A technique in which a filter is interposed has been developed. However, such a rectangular air filter Which is different from the shape of a cylindrical pipe through which air flows, was required to have a bulky and large-sized housing case, which had a problem of taking up a lot of space when installed in a small place such as a car.
Techniques which are constructed in a cylindrical or cylindrical shape so that the air filter can be installed even in a narrow place are disclosed in Korean Patent Application Publication No. 25040 (published on Nov. 17, 1994), published patent application No. 120019 As disclosed in commonly-published Japanese Patent Application No. 70801 (published on June 28, 2010), a plurality of such conventional cylindrical air filters have been provided in the center of the hollow space, The peripheral portion of the hollow space spaced apart from the housing or the casing is secured on the outside of the filter to allow the air flowing in the longitudinal direction of the pipe to flow into the central portion and then to the peripheral portion or to the peripheral portion and then to the central portion. Similarly, a conventional cylindrical air filter requires a casing having a diameter larger than that of a pipe through which the air flows, The air flowing in the longitudinal direction of the pipe passes over the filter paper without passing through the filter paper, and if the center portion and the peripheral portion are not spaced apart from each other, Since the conventional cylindrical air filter and the filter housing casing have a larger diameter than the air flowing pipe in order to secure the empty space in the peripheral portion, they can not be installed directly in the pipe, which is a narrow place, It was difficult to install in a narrow place, and the filter efficiency was significantly reduced as the size of the air filter was reduced.
The present invention has been made to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide an air purifier which can prevent the air from flowing into the central portion of the inner pipe after being permeated to the peripheral portion thereof, It is difficult to install a conventional cylindrical air filter inside a pipe by forming a space in a center portion and a peripheral portion. In contrast, in the present invention, a filter paper for filtering air is internally fixed inside a pipe through which air to be filtered flows, The filter paper is folded back and forth along the longitudinal direction of the pipe and the tube while the zigzag folded edge of the filter paper is formed radially from the center of the tube so that the air flowing in the longitudinal direction inside the pipe flows in front of the filter paper To backward The installation space can be minimized to the inside of the pipe. Nevertheless, since the filter paper takes a zigzag shape in the longitudinal direction of the pipe, which is the flow direction of the air, so as to maximize the filter efficiency The present invention has been completed based on the object of the present invention to provide a pipe type air filter.
According to the present invention, there is provided a pipe-type air filter, wherein the pipe-type air filter of the present invention has a shape corresponding to the inside of the pipe so that air can be housed inside the pipe to be transferred A hollow tube is constituted, and a zigzag folded edge located at the front and rear in a zigzag form folded back and forth in the lengthwise direction of the pipe is formed inside the tube with a filter paper having radially equidistant gaps from the center of the tube toward the inner surface of the tube The filter may be installed at the center of the tube and the filter paper may be attached to the outside.
And an inner tube which is located at the center of the tube and is attached to the outer side of the inner tube and which is folded back and forth in a zigzag fashion in the lengthwise direction of the pipe, The zigzag folded edges may be provided with inner filter paper having a radially equal spacing from the center of the inner tube toward the inner surface of the inner tube.
In addition, the front of the tube may be inscribed in the pipe, and the rear of the tube may be inclined to be smaller than the front.
According to a specific means for solving the above-mentioned problems, the pipe-type air filter of the present invention is characterized in that a filter paper having a staggered shape in the longitudinal direction of the pipe is inserted and installed inside the tube, The air filter can be installed inside the flowing pipe, so that the filter can be filtered in a narrow space inside the pipe.
In addition, in the air filter of the present invention, the filter paper provided inside the tube does not have a zigzag form on the opposite side only, but the front and rear edges folded back and forth are zigzagged radially toward the inner surface from the center of the tube, The air flowing through the pipe contacts the inner surface of the pipe so that the flow velocity is the highest at the pipe center portion rather than the edge portion where a large amount of friction is generated. In the present invention, the filter paper at the center portion of the tube is most densely packed, So that the air filter efficiency of the pipe can be maximized.
The pipe type air filter according to the present invention is characterized in that the filter paper has a zigzag shape in the longitudinal and longitudinal direction of the pipe inside the tube as described above, It is most suitable to filter air of pipe type and maximizes the filter efficiency. Therefore, it is most suitable for the pipe, so that the product response of the air filter And it can contribute to the expansion of the base of the product due to the increase.
