Description

[Detailed Description of the Invention] The present invention relates to an improved ventilation fan that prevents the surface of the decorative frame from being contaminated by oil and dust.

In ventilation fans, especially those used in kitchens, etc., the surface of the decorative frame that surrounds the ventilation blades that are rotated by a motor has traditionally been used to prevent oil stains from cooking, and especially smoke in the air. There is a problem in that they are contaminated by so-called oil dust, such as dust contained in them, and cleaning them is a major hassle.

Therefore, in recent years, it has been considered to cover the surface of the decorative frame with a removable synthetic resin film, for example, and with this, the surface of the decorative frame is not soiled, only the film is stained. The coating can be removed all at once by peeling it off from the surface of the decorative frame, which saves the effort of cleaning and is very convenient. There is a problem that the coating is easily torn and torn, and this can cause all of the coating to be peeled off, leaving behind fragments of dirt and making it look unsightly, or even if it can be removed, the peeling operation is troublesome. In particular, such a problem is more likely to occur when multiple layers of coatings are laminated and are in close contact with each other, and the problem becomes even more problematic.

The present invention was devised in view of the above-mentioned circumstances, and its purpose is to be able to completely remove the film covering the surface of the decorative frame without breaking it, leaving no stain behind, and making it highly practical. Provide a ventilation fan that can be closed.

An embodiment of the present invention will be described below with reference to the drawings. First, in FIG. 1, 1 is an outer frame, 2 is a motor mounting leg installed vertically inside the outer frame 1, and A motor 3 is attached to a mounting leg 2, and a ventilation blade 5 is attached to a rotating shaft 4 of the motor 3.

Therefore, the ventilation blades 5 are rotationally driven by the motor 3, and the rotation thereof causes forced ventilation from the indoor side at the front of the outer frame 1 to the outdoor side at the rear for ventilation.

Reference numeral 6 denotes a decorative frame attached to the front part of the outer frame 1, which has a so-called bell mouth by surrounding the ventilation blades 5. It is covered with a peelable coating 7 made of, for example, synthetic resin as shown in the figure, and this coating 7 has beads 8 and 9 thicker than other parts on both the inner and outer peripheral edges, respectively, as shown in FIG. is forming.

Now, in the case of this embodiment configured as described above, both the inner and outer peripheral edges of the coating 7 are reinforced by the beads 8 and 9, and therefore, the coating 7 is peeled off in order to remove dirt caused by attached oil dust, etc. In this case, no cracks or the like are formed from the reinforced peripheral edge as described above, and the coating 7 can be peeled off smoothly without any damage.Of course, this means that the coating 7 is The same is true even when the materials are stacked and in close contact with each other, and by doing so, it is possible to remove all dirt and improve the cleanliness and appearance.

By the way, if the peripheral edge of the coating 7 were to remain thin without beads 8 and 9, it would be very difficult to hold the peripheral edge of the coating 7 when peeling it from the decorative frame 6. However, in the end, it is necessary to pry the peripheral edge of the coating 7 from the surface of the decorative frame 6 using a sharp-edged tool or nail, etc. This takes time and effort to peel off the coating 7, and it is difficult to remove the decorative frame 6. There is also a risk of injury.

In this regard, according to this embodiment, since the thick beads 8 and 9 are provided on the peripheral edge of the coating 7, the beads 8 and 9 can be easily picked, and therefore the coating 7 can be peeled off very easily. At the same time, it is possible to prevent the decorative frame 6 from being damaged.

The peeled off film 7 may be discarded together with the attached dirt, but it may also be constructed so that it is reused after removing the dirt, especially when it is reused in this way. The reinforcement of the peripheral edge of the coating 7 by the beads 8 and 9 is more effective in making the coating 7 last longer.

However, the beads 8 and 9 do not have to be present on both the inner and outer peripheral edges of the coating 7; it is sufficient if one of them exists only on at least the outer peripheral edge of the coating 7.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but can be modified in various ways without departing from the spirit of the invention.

As explained above, the present invention consists of covering the surface of a decorative frame that surrounds ventilation blades that are rotationally driven by a motor with a removable coating that has thicker beads on the periphery than other parts. By doing this, all the coating on which dirt such as oil dust has adhered to the surface of the decorative frame can be removed smoothly without breaking, and therefore no dirt remains, improving cleanliness and improving the appearance. In addition, it is possible to easily pick up the beads and peel off the film very easily, and also to ensure that the decorative frame is not damaged during the peeling, thereby providing a highly practical ventilation fan. It is something.

[Brief explanation of the drawing]

The drawings show one embodiment of the present invention; FIG. 1 is an overall longitudinal sectional side view, FIG. 2 is an enlarged perspective view of the coating alone, and FIG. 3 is an enlarged longitudinal sectional side view of the main part. In the figure, 3 is a motor, 5 is a ventilation blade, 6 is a decorative frame, 7 is a coating, and 8 and 9 are beads, respectively.
