FIG. 6 is a cross-sectional view illustrating a ventilator in which a filter unit can be easily disassembled according to another embodiment of the present invention.

The basic structure of the embodiment of FIG. 6 is the same as that of the embodiment of FIGS. 2 to 6 except that the support block 30 'is structured so as to more firmly fix the filter unit 20.

6, the present embodiment is characterized in that the support block 30 includes a block 31 ', a rotary member 32', a vertically movable portion 33 'and a pressing portion 34' do.

The block portion 31 'is formed in a substantially rectangular parallelepiped shape, and an insertion groove 31 is formed upwardly at one end bottom surface.

The block portion 31 'is provided at one side of the supporting piece 13 with the supporting piece 13 inserted into the insertion groove 31'a and one side of the bottom surface of the filter unit 20 is supported on the upper surface side And serves to prevent the filter unit 20 installed inside the support frame 10 from being deviated downwardly of the support frame 10.

The block 31 'is formed with a guide groove 31'b having a length in the vertical direction and inserted into the protrusion 34'b at one side corresponding to the later-described protrusion 34'b.

The rotary member 32 'is formed in a substantially disc shape and is rotatably installed inside the block 31' in the horizontal direction. One side of the rotary member 32 'is exposed in the direction of the insertion groove 31'a, when one side of the supporting piece 13 is inserted into a side of the supporting piece 13, one side of the outer side is in contact with the side surface of the supporting piece 13. [

When the block member 31 'moves to a position corresponding to the vicinity of the vertex of the filter unit 20 in a state where the support piece 13 is inserted into the insertion groove 31'a, And serves to provide a moving force to the up-and-down moving part 33 ', which will be described later, while being rotated by the frictional force with the part 13. [

Here, it is preferable that the slip prevention member 32'a of rubber material having a high friction coefficient is coupled to the outer surface of the rotary member 32 'so that the rotary member 32' can be easily rotated by the frictional force with the support piece 13.

 The upper and lower upper and lower portions 33 'are formed in a bar shape having threads on the outer surface thereof and are arranged in the vertical direction inside the block portion 31', and are rotatably disposed in the circumferential direction. And the other side is screwed to the center of the rotary member 32 'so as to move up and down when the rotary member 32' rotates.

The pressing portion 34 'includes a pressing body 34'a provided on the upper portion of the upper and lower moving portion 33' and a pressing portion 34'a extending outwardly from both sides of the pressing body 34'a, And a protrusion 34'b inserted into the guide groove 31'b of the rotary body 32'to prevent the pressing body 34'a from rotating together with the rotary body 32'rotated, When the moving part 33 'is moved upward, it is moved upward so as to press the one side of the bottom surface of the filter unit 20 upward, thereby fixing the filter unit 20 more firmly.

In order to install the filter unit 20, one end of the support block 30 'is inserted into the inlet hole 13a of the support piece 13, At this time, one side of the support piece 13 is inserted into the insertion groove 31'a of the support block 30 '.

When one side of the support piece 13 is inserted into the insertion groove 31'a, the support block 30 'is moved to a position corresponding to the vicinity of the vertex of the filter unit 20. At this time, the slip prevention member 32'a Is brought into contact with one side of the side surface of the support piece 13.

During the movement of the support block 30 ', the rotary member 32' is rotated in the horizontal direction by the frictional force between the support piece 13 and the slip prevention member 32'a, and the rotary member 32 ' As it rotates, the upper and lower portions 33 'are moved upward by the threads formed on the outer surface.

The pressing portion 34 'provided on the upper portion of the upper and lower moving shaft 33' moves together with the upper and lower moving portions 33 'to move upward and firmly press the bottom surface of the filter unit 20.

On the other hand, the method of releasing the filter unit 20 is the reverse order of the above-described method, and the other structures are the same as those of the above-described basic embodiment, and the remaining description will be omitted.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications and variations without departing from the spirit and scope of the invention. Accordingly, the appended claims are intended to cover such modifications or changes as fall within the scope of the invention.
