Description

[Detailed explanation of the invention] This invention is designed to prevent stains on the surface of the decorative frame due to oil dust, etc.
A ventilation fan that takes measures to easily remove this is concerned.

Ventilation fans, especially ventilation fans for cooking rooms, have the problem that the surface of the decorative frame surrounding the ventilation blades becomes contaminated with so-called oil dust, such as oil dust and airborne dust generated during cooking, and cleaning it requires a great deal of effort. It was time consuming.

Recently, it has been considered to cover the surface of the decorative frame with a coating when spraying a removable vinyl chloride solvent, for example.According to this, only the coating would be contaminated, and the contamination would be on the surface of the decorative frame. Since the coating can be easily removed by peeling off the coating, cleaning can be simplified and convenient.

However, this spraying method has a problem with the film formation method: when the coating paint is sprayed onto the decorative frame, the paint scatters outside the decorative frame, contaminating the floor or wall on the back side of the decorative frame. There was a need for a solution to this fear.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to cleverly utilize packaging boxes that lose their useful value after being unpacked and are eventually discarded, so that floors or walls can be contaminated with coating paint. The purpose is to provide a ventilation fan that can prevent this from happening.

An embodiment of the present invention will be described below with reference to the drawings.

In Figure 1, 1 is the outer frame of the ventilation fan body, 2 is a motor mounting leg installed inside the outer frame 1, a motor 3 is attached to this mounting leg 2, and a ventilation blade 4 is attached to the motor 3. has been done.

The ventilation blades 4 are rotationally driven by the motor 3, and thereby ventilate from the indoor side at the front of the outer frame 1 to the outdoor side at the rear.

Reference numeral 5 denotes a shutter pivotally installed at the rear opening of the outer frame 1 to open and close it, 6 a connecting rod connected to the shutter 5, 1 a drawstring for opening and closing the shutter 5 via the connecting rod 6, and 8 a motor. 3 is a switch mechanism arranged at the lower part of the outer frame 1 to turn off the power.

In addition, 9 is a decorative frame made of plastic, for example, which is removably attached to the front opening of the outer frame 1. As shown in Fig. 2, this is a bell mouth which is an intake port that also serves as an oil and dust receptacle. 1
0 is integrally formed, and this bell mouth 10 surrounds the ventilation blades 4.

Now, in Fig. 3 I, 11 is a slow-closing member, which is made of a cardboard inner material that was included in the packaging box to hold down a ventilation fan, among the parts provided with the packaging device. It is designed so that it can be held suspended using a string or the like.

Reference numeral 12 denotes a cutout plate portion formed by inserting a first perforation line, for example, perforation A, in this slow closing member 11 so as to match the outer contour of the decorative frame 9; 13, this cutout plate portion 12;
Make a second cut line, for example perforation B, on the bell mouth 10
This is a separation plate portion formed by inserting a hole so as to match the inner contour shape of the tip portion of the holder.

If a portion of the perforation A of the cutting plate portion 12 is pressed slightly forcefully with a finger, that portion will break.

Then, when the user moves around along the perforation A while intermittently pressing the broken part with his/her finger as a starting point, the cutting plate part 12 is cut out from the slow closing member 11 as shown in FIG. A rectangular opening 14 into which the decorative frame 9 is fitted and held is formed in the opening.

In addition, when the perforation B of the separation plate part 13 is operated in the same manner as described above in the resection plate 12 after the excision, the separation plate part 13 is separated into separated circular shapes as shown in FIG. This becomes a separation plate part 13, which is fitted in the innermost part of the bell mouth 10 as shown in FIG. 6I.

15 is a perforation line C at the upper part of the slow closing member 11.
This is a through hole for suspension, which was formed by inserting a circular hole into the hole and cutting out the inside in the same manner as described above.

Now, in order to form a coating by spraying, the decorative frame 9 is fitted and held in the opening 14 of the slow-closing member 11, and then the separated separation plate 13 is pushed into the bell mouth 10, and the Insert.

In this state, the late-closing member 11 is connected to the through hole 15 by the string 16 or the like.
(See Figures 5 and 6).

On the other hand, numeral 17 is a spray can, and a coating paint in which a vinyl chloride-based member is diluted with an appropriate solvent is contained in this can.

When this coating paint is sprayed from the spray can 17 towards the surface of the decorative frame 9 which is in the suspended state I together with the slow closing member 11,
The coating paint adheres to the surface of the decorative frame 9 to form a coating 18.

At this time, the coating paint deviates from the decorative frame 9 and scatters around its outer periphery, but this is blocked by the slow-closing member 11, so that the room walls, furniture, etc. can be prevented from being contaminated.

Further, when the coating paint is sprayed from the spray can 17 toward the bell mouth 10, a coating 18 is formed on the inner peripheral surface of the bell mouth 10.

At this time as well, the paint film that deviates from the bell mouth 10 is blocked by the separation plate 13 fitted thereto, so that the paint film does not scatter to the outside.

Therefore, according to this embodiment, when the coating paint is sprayed from the spray can 17 onto the decorative board 9 and the bell mouth 10, it is possible to reliably prevent the coating paint from scattering behind them.

As a result, the furniture, walls, etc. are not contaminated, so they can be kept clean.

Incidentally, the slow-closing member 11 may be placed on the floor so as to be placed against a wall for application, and of course, in this case as well, adhesion of the paint to the floor or wall can be reliably prevented.

Moreover, since there is no need to apply carefully to prevent the coating paint from scattering to areas other than the decorative frame 9, the coating can be performed quickly and work efficiency can be improved.

In addition, since the slow-closing member 11 and the separating plate part 13 are made of a cardboard interior material as part of the packaging box, the cost is not increased.

In addition, the slow closing member 11 has an opening 14 and a separated separation plate 1.
Since the configuration is such that perforations are made as perforation lines to form the parts 3, each part can be formed easily and with good appearance.

In this embodiment, the slow-closing member 11 is constructed from a cardboard material used to hold down the ventilation fan inside the packaging box, but it goes without saying that the slow-closing member 11 may also be constructed using the side walls of the packaging box. .

Further, the cutting line may be not only a perforation but also a simple printed line, and in this case, it is sufficient to cut along the printed line with scissors or the like.

Other vehicle designs are not limited to the embodiments described above and shown in the drawings, and can be implemented with appropriate modifications within the scope of the invention.

As described above, the present invention has a structure in which a part of the packaging member constituting the packaging box is provided with a cutting plate part and a separation plate part surrounded by cutting lines that match the shapes of the decorative frame and the bell mouth. As a result, when spraying removable film paint onto a decorative frame, it is possible to reliably prevent the warped film paint from adhering to walls or furniture, and moreover, it is possible to effectively use packaging materials. Since it is used to achieve the intended purpose, it has practical effects such as not causing an increase in costs.
