Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ventilation fan cover, and more particularly, to an aluminum foil cover that covers the entire ventilation fan.

[0002]

[Problems to be solved by conventional techniques and devices]

 Ventilation fans used in home kitchens, etc. are installed almost directly above the range so that oil and other substances generated from the range do not scatter around, and have an opening on the front facing the rotating blades, and the whole box. It is of a type. However, as the amount of oil adheres to the blades of the ventilation fan etc. as the usage period elapses, it will drop if the amount increases, and it will take a lot of time and effort to remove it by cleaning. Exhaust fan covers are often used.

Most conventional ventilation fan covers cover only the opening formed in the front surface of the ventilation fan, as proposed in Japanese Utility Model Laid-Open No. 58-35729. The ventilating fan cover having such a shape is a frame made of synthetic resin or the like and having a trapezoidal shape as a whole, a filter is attached to the front surface, and a fastening portion is formed on the peripheral edge of the side surface of the trapezoidal portion. This fastening part can be attached to the front of the ventilation fan using a fastening tool such as a suction cup.

However, since the conventional ventilation fan cover is a type that partially covers only the front surface of the ventilation fan, neither side surface of the ventilation fan main body is covered, so that the amount of oil that is not sucked into the ventilation fan as the use period elapses. There was a drawback that it adhered to the side surface and became very dirty, and it had to be cleaned and removed.

An object of the present invention is to solve the above-mentioned drawbacks of the prior art and to provide a ventilating fan cover that prevents the entire ventilating fan from being contaminated by oil or the like.

[0006]

[Means for Solving the Problems]

 As a means for solving the above problems, the present invention provides a cover used for a ventilation fan that has an opening on the front surface and a power cord, a switch cord, etc. on the side surface. It is a box-shaped cover made of aluminum foil that covers the side surface, and a window with a filter is provided on the front side, one opening hole for taking out the switch string is provided on the lower side surface, and one on the left and right sides. The feature is that each has an opening for taking out the power cord.

The present invention will be described in more detail below.

【Example】

Since the ventilating fan cover of the present invention is a cover that entirely covers the ventilating fan main body, the ventilating fan cover is entirely box-shaped in consideration of the box-shaped ventilating fan. That is, as shown in FIG. 1, the ventilating fan cover 1 is a box-shaped body including a front surface 2, an upper side surface 5 around the front surface 2, a lower side surface 6, and left and right side surfaces 7 and 8. The body of this cover 1 is made of aluminum foil. Normally, aluminum foil is molded (normally it is an integral molding, but it can be molded separately) to form a box shape. At that time, it is preferable to form reinforcing ribs on each side surface. Further, a window portion 3 having an appropriate shape (circle, rectangle, square, etc.) is formed on the front surface of the cover in order to attach the filter 4 made of non-woven fabric or the like. The window may be opened over the entire surface, but it is preferable that the window has an appropriate pattern in order to stretch the filter by heat sealing or the like.

As a pattern of the window portion 3, for example, a pattern in which four filter exposed portions are formed by ribs in a cross shape shown in FIG. As another example of the pattern, as shown in FIG. 2, three filter exposed portions are arranged symmetrically. In this case, since a relatively wide rib is formed in the center, it is easy to bend to the left and right, and when the cover is attached on the left and right side surfaces, it has an advantage that it fits well to the shape and dimensions of the ventilation fan body. In addition, since the ventilation fan is usually installed at a high place, it is easier to install the left and right sides than the upper side of the cover.

Furthermore, the ventilation fan cover of the present invention has a shape that does not impair the functions of the power cord, switch cord, etc. attached to the ventilation fan. That is, the ventilation fan body is usually designed so that the power cord is attached to one of the left and right sides, and the switch cord is attached to the lower side. In consideration of this point, the ventilation fan cover is provided with opening holes 9 for taking out the switch string on the lower side surface 6, but one opening is provided on each side. As a result, the switch cord can be attached to either the left side or the right side. Further, for the same reason, the opening holes 10 for taking out the power cord are provided on the left and right side surfaces, respectively.

The opening hole 10 for taking out the power cord may be a hole having an appropriate shape and dimension because the power cord does not move during use of the ventilation fan. On the other hand, the opening 9 for the switch string may move left and right because the switch string moves up and down each time it is used. Also, even if the switch string installation position is slightly different depending on the specifications of the ventilation fan, It is preferable that the holes are elongated in the left and right directions.

As described above, the ventilation fan cover is a box type that covers the entire ventilation fan main body and is made of aluminum foil, so that the entire ventilation fan cover can be easily covered from above during installation. . Since aluminum foil has excellent holdability, it can be attached simply by pressing the side of the cover against the ventilation fan body. At that time, since the ventilation fan vibrates during use, in order to attach it more securely, as shown in Fig. 3, attach a suitable adhesive such as double-sided adhesive tape to the inside of the appropriate parts such as the front, top and bottom sides, left and right sides of the cover. It is preferable to bond it to the ventilation fan main body with the garment 11. In the figure, 13 is a ventilation fan main body, and 14 is a rotating blade of the ventilation fan.

Further, as shown in FIG. 4, it is desirable to form the attachment flaps 12 on the left and right side surfaces 7 and 8 because the attachment with a fastening tool such as an adhesive tape becomes easier. Since this flap is an extension part with a certain width from the peripheral edges of the left and right sides as shown in the figure, it usually protrudes from the main body of the ventilation fan, so it should be attached to the wall around the ventilation fan main body such as tile or stainless steel. Become. When attaching, use appropriate fasteners such as double-sided adhesive tape or suction cups.

[Effect of device]

 As described above, according to the ventilation fan cover of the present invention, it is possible to prevent the entire ventilation fan from being contaminated by oil or the like. In addition, it is compatible with various types of ventilation fans, and it is economical because it can be reused because it is made of aluminum foil.
