Is detachably mounted to the front part of the above-mentioned decorative frame 9.

&Quot; 51 " is made of a nonwoven fabric as a filter, made of a band shape, and wound around a roller 52 made of, for example, a thick paper.

On the other hand, "53" is similarly a winding roller made of thick paper, and the winding end of the filter 51 is attached to the winding roller 53.

In addition, at the right end of the winding roller 53, as shown in FIG. 4, a fitting having a shape corresponding to that of the above-described engagement structure 38, which is one component of the above-described operation transmission mechanism 22, is engaged. A cylindrical portion 57 formed with a circumference 55 surrounding the periphery of the structure 54 and a blade portion 56 protruding further outward is fitted.

Therefore, as shown in FIG. 1, with respect to the filter 51 and the winding roller 53, the left end of the roller 52 is pushed against the elastic force of the spring 14 described above to push the support plate 13 described above. The filter 51 is rotatably supported in the recess 10 by being inserted into the hole 12 while being inserted, and by inserting the right end portion into the hole (not shown) facing the hole 12.

Meanwhile, the filter 51 is pulled out, and the left end of the winding roller 53 is inserted into the hole 15 while pushing the support plate 16 described above against the elastic force of the spring 17, as shown in FIG. As shown, the winding roller 53 is engaged by engaging the engaged structure 54 with the engaging structure 38 while fitting the circumferential portion 55 to the shaft cylindrical portion 40 of the unit 20 described above. It was connected to the unit 20 mentioned above by being rotatably supported and installed in the recessed part 11.

Accordingly, the front surface of the filter accommodating portion 49 described above is crossed from the upper edge on one side of the front portion of the decorative frame 9 (front portion of the ventilator main body “1”) to the lower edge on the other side, so that the filter The 51 is designed to cover the front part of the decorative frame 9 (front part of the ventilation apparatus main body 1).

"58" is also a filter pressing part, which is mounted on the decorative frame 9 in front of the filter 51 so as to be attached thereto.

&Quot; 59 " is an oil receiving portion detachably mounted to the decorative frame 9 located below the decorative frame 9, the filter accommodating portion 49 and the filter pressing portion 58, &Quot; 60 " is a spacer serving as a filter guide provided at both end portions (only one end portion) of the front portion of the filter accommodating portion 49 described above.

In the case of the above-described configuration, when the pull string 7 is pulled and operated by the operating mechanism 8, the shutter 6 is opened and the motor 4 is energized so that the blower blade 5 is driven to rotate. Accordingly, indoor air is sucked into the ventilator main body 1 through the filter 51 and discharged to the outside through the shutter 6 part in the open state.

Then, by being attached to and removed from the filter 51, such as oil and dust contained in the sucked air, the filter 51 is gradually dirty and finally reaches a time when the replacement is necessary.

Thus, when the filter 51 needs to be replaced in this way, in the present embodiment, the pull string 28, which is the pull operation member, is pulled downward to operate.

Then, the stopper 29 is pulled so that the rotating plate 26 is rotated, and each vertical surface 33a of the teeth 33 of the one-way clutch 31 in this rotational direction (counterclockwise rotational direction in FIG. 5) is rotated. Engaged in the hole 32, external power is transmitted to the drive gear 25, so that the drive gear 25 is rotated in the same direction.

Accordingly, the stopper 41 is pushed by the inclined surfaces 42b of the teeth 42 of the cogwheel 37, and the driven gear 36 meshed with the drive gear 25 causes the cogwheel 37 and the engaging structure to be engaged. Rotating together with (38), the rotation is also transferred from the engagement structure (38) to the engagement structure (54), so that the winding roller (53) is rotated through the cylindrical body (57) to filter (51). Is wound.

In addition, when wound in this way, the filter 51 is rotated together with the roller 52 to draw a new part.

Thus, after the pulling operation of the pulling string 28 is performed until the stop 29 of the rotating plate 26 is pulled to the end, the pulling of the pulling string 28 is released, and the rotation of the rotating plate 26 until this time is performed. The spring 34 in the state of being wound along with the accumulation of the elastic force releases the elastic force to rotate the rotating plate 26 in the clockwise direction in FIG.

At this time, the vertical surface 42a of the teeth 42 closest to the distal end of the stopper 41 is caught by the distal end of the stopper 41 so that the gear 37 stops rotation in the return direction. The structure 38 and the driven gear 36 are stopped in the return direction, respectively, and the winding roller 53 and the drive gear 25 are respectively stopped in the return direction.

At this time, the inclined surfaces 33b of the teeth 33 of the one-way clutch 31 come out of the holes 32 and are in sliding contact with the surface of the rotating plate 26 side of the drive gear 25, whereby the rotating plate 26 is Since the spring 34 is pushed out by the height of the teeth 31 of the clutch 31 to be separated from the driving gear 25, only the rotating plate 26 is rotated in the stopped state.

Therefore, the winding roller 53 is maintained at a stationary state and the pulling string 28 is pulled up, where the operation of pulling the pulling string 28 downward again again, as described above, the winding roller 53 is When the filter 51 is rotated so as to be wound, and then the pulling string 28 is released, the winding roller 53 is kept stationary and the pulling string 28 is pulled up.

Therefore, the entire dirty part of the filter 51 is wound up by repeating such an operation, and the front part of the decorative frame 9 (front part of the ventilator main body 1) is covered by the new part instead. .

Therefore, when the newly replaced part of the filter 51 becomes dirty again and needs to be replaced, as described above, the pulling operation of the pulling string 28 is performed a plurality of times, and the decorative frame is formed by another new part of the filter 51. The front part of 9) (the front part of the ventilator main body 1) is covered.

In addition, when the winding operation can no longer be performed using all of the filters 51, the oil receiving part 589 and the filter pressing part 58 are separated from the decorative frame 9, respectively, and the left end of the roller 52 is removed. To the inside of the hole " 12 " while pushing the support plate 13 against the elastic force of the spring 14, and in this state, the right end of the roller 52 facing the hole " 12 " (not shown). The filter 51 is pulled out of the recess 10 by pulling out from the hole and the other left end from the hole " 12 ".

On the other hand, the left end of the winding roller 53 is inserted into the hole " 15 " while pushing the support plate 16 against the elastic force of the spring 17, and in this state the fitting structure 54 is engaged with the fitting structure ( 38), the winding roller 53 is pulled out from the recess 11 by pulling out from the left end hole " 15 " of the other winding roller 53. As shown in FIG.

Then, the filter 51 and the winding roller 53 removed in this way are discarded. Instead, the new filter 51 and the winding roller 53 are mounted as described above, and the filter pressing part 58 and the oil receiving part are installed. Attach and use (59).

As described above, according to the present embodiment, by pulling the pull string 28, which is the pull operation member hung downward from the ventilator main body 1, the winding roller 53 is rotated through the operation transmission mechanism 22 to filter. By winding 51, it is possible to operate the winding without difficulty without using a footrest or the like even for a ventilation device normally located at a high place.

In addition, during the winding operation, even if the wall surface of the house is located behind the pull string 28 described above, since it is different from the conventional dials and handles of the pull string 28, it is possible to operate without touching the wall surface. Unlike the dial and the handle to operate one rotation of the pull just because the pull 28 to operate it can be operated without any hassle.

Therefore, since the operation is simple, the winding of the filter 51 can be reliably performed, thereby avoiding the problem that the extra winding or the winding amount is insufficient.

Further, according to the above embodiment in which the operation transfer mechanism 22 is configured such that the filter 51 winds up one side of the front part of the ventilator main body 1 by pulling the pull string 28 a plurality of times, Compared with performing the filter winding operation, the gear mechanism can be simplified and the operating force can be reduced.

However, the present invention is not limited only to the above-described matters and the embodiment shown in the drawings, so that the filter 51 winds up one side of the front part of the ventilator main body 1 by pulling the pull string 28 once. It is preferable to make it possible, and the specific structure is not limited as mentioned above.

In addition, the winding direction of the filter 51 may be made into the direction from bottom to top opposite to what was mentioned above.

Furthermore, the wound filter 51 may be formed in a folded state rather than in a rolled form that is wound around the roller 52. In addition, there is no plural batches and only one work is needed to replace the filter. It may be possible to carry out without dirtying hands.

In addition, for example, the pulling operation member may be made of a wire or a plate in addition to the pulling string 28.

As can be clearly seen from the above description, the filter-mounted ventilator of the present invention installs the filter in the ventilator body across from one side of the front part of the ventilator body to the other side, and also installs the filter on the other side. It is designed to be wound by a single winding roller, and has a pulling operation member which extends downward from the above-mentioned ventilation apparatus main body, and converts the pulling operation member pulling operation into a rotational motion and transmits it to the above-mentioned winding roller. It is characterized by having a delivery mechanism, whereby an excellent effect can be obtained in which the winding operation of the filter can be performed simply and reliably without difficulty.
