Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ventilation fan that is improved in order to deal with stains on the surface of a decorative frame due to oil dust and the like.

In ventilation fans, especially ventilation fans installed and used in kitchens, etc., the surface of the decorative frame that surrounds the ventilation blades that are rotated by a motor has traditionally been contaminated with oil stains generated during cooking and especially in the air. There was a problem of dirt being contaminated by so-called oil dust, such as dust contained in smoke, and cleaning it was a great hassle. Therefore, in recent years, it has been considered to cover the surface of the decorative frame with a removable film, for example, painted with a synthetic resin liquid. According to this method, the surface of the decorative frame becomes dirty just by staining the film. No,
The dirt can be removed all at once by peeling off the coating from the surface of the decorative frame, which saves the effort of cleaning and makes cleaning very convenient. There is no gripping part for this purpose, so there is a drawback that the coating is really difficult to peel off, and it is also very likely that your fingertips will get hurt as you try to pry the coating off with your nails.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a ventilation fan from which the coating covering the surface of a decorative frame can be easily peeled off without damaging fingertips or the like. be.

Embodiments of the present invention will be described below. First, in the first embodiment shown in FIGS. 1 to 3, 1 is an outer frame, 2 is a motor mounting leg inside the outer frame 1, a motor 3 is attached to this mounting leg 2, and a motor 3 is attached to the motor 3. ventilation blade 4
is attached by a spinner 5. Therefore, the ventilation vanes 4 are rotationally driven by the motor 3, and by the rotation thereof, forced ventilation is performed from the indoor side at the front of the outer frame 1 to the outdoor side at the rear. ing. Note that 6 is located at the opening on the outdoor side (rear side) of the outer frame 1, and rotates the ventilation blade 4,
A shutter that is opened and closed when the shutter is stopped; 7 is a switch box with a built-in switch mechanism that controls the opening and closing of the shutter 7, the rotation of the ventilation blade 4, the stop and therefore the conduction to the motor 3, and the disconnection of electricity; 8 is a pull cord for operating the shutter; It is. Therefore, 9 is the switch box 7 and the drawstring 8.
It is a decorative frame that is removably engaged with the opening on the indoor side (front side) of the outer frame 1 where the frame 1 is located, and has a bell mouth 10 that is an intake port that also serves as an oil dust receptacle. It surrounds the ventilation blade 4. Here, reference numeral 11 denotes a coating that covers the entire surface of the decorative frame 9, and is made of a vinyl chloride-based plastic material, diluted appropriately with a solvent, and applied by a coating method such as spraying or dipping, and is removable. A peeling knob 12 is provided by extending outward from the rear edge of the central portion of the lower side a string that is partially embedded between the back surface of the coating 11 and the surface of the decorative frame 9. It is set up.

In the first embodiment configured as described above, when the knob 12 is grasped and pulled toward the user, a portion of the coating 11 around the knob 12 is first peeled off from the surface of the decorative frame 9. Therefore, if you then hold a part of the peeled coating 11 and pull it, the tensile force that spreads from that part to the entire coating will of course easily pull the entire coating 11 apart. Therefore, it is more convenient to remove dirt such as oil dust that has adhered to the coating 11 instead of the surface of the decorative frame 9, and there is no need to pry the coating 11 with your nails. The work can be carried out extremely safely without causing any damage to fingertips, etc.

4 and 5 show a second embodiment of the present invention, in which reference numeral 13 is a coating that replaces the aforementioned coating 11, and 14 is a knob formed integrally with this coating 13 using so-called paint dripping. Since the coating 13 can be peeled off by holding this knob 14, the same effects as described above can be obtained.

Next, FIGS. 6 to 8 show a third embodiment of the present invention, in which reference numeral 15 denotes the coatings 11 and 13 described above.
The coating 16 in place of the coating 16 is a separate tape tab that is embedded in each corner between the back surface of the coating 15 and the front surface of the decorative frame 9 and extends outward from the corner. Then, by pulling the knob 16, the coating 15 is broken and separated from each of the corners, and in particular, as shown in FIG. 8, the surrounding area is flattened and then peeled off. Despite the differences, the same effect as described above can be obtained.

Further, FIGS. 9 and 10 show a fourth embodiment of the present invention, in which 17, 18, and 19 are three layers instead of the aforementioned coatings 11, 13, and 15. The provided coatings 20, 21, and 22 are knobs provided at different positions on the coatings 17, 18, and 19 of each layer, and the same effects as described above can be obtained for each layer. In addition, there is an advantage that the coatings 17, 18, 19 of each layer can be peeled off in an orderly manner. In this case, the knobs 20, 21, and 22 are each marked with, for example, a number indicating the order of peeling. effect can be obtained.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but may be modified as appropriate without departing from the scope of the invention, such as by providing a knob on a surface other than the edge of the coating. It can be implemented with modifications.

As described above, the present invention has a motor and a ventilation blade rotationally driven by the motor, and a decorative frame surrounding the ventilation blade, the surface of the decorative frame can be peeled off, and the surface of the decorative frame can be peeled off. It is covered with a painted film that has a knob, which allows the film to be peeled off easily and reliably without damaging fingertips, etc., and is therefore more effective in removing dirt such as oil dust. It is possible to provide a ventilation fan that is convenient and safe.
