The sheet-shaped nonwoven fabric 51
After covering the surface of the metal filter main body 41 disposed at the exhaust port in the hood 40a of the range hood 40, a plurality of magnets 55 as fixing means are arranged near the periphery of the sheet-like nonwoven fabric 51. The sheet-like nonwoven fabric 51 was fixed to the filter body 41. Further, as a fixing means of the sheet-like nonwoven fabric 51, a magic tape (trade name), a double-sided tape, a glue or the like can be used instead of the magnet 55. A method of attaching the sheet-like nonwoven fabric 51 in the case of using such fixing means is, for example, attaching a double-sided tape to the vicinity of the periphery of the metal filter main body 41 at a plurality of locations, and attaching the sheet-like nonwoven fabric 51 to these double-sided tapes. It was fixed by doing.

Another example of a conventional range hood filter is shown in FIG. In the range hood filter 61, an annular insertion hole 64 is formed on the periphery of the nonwoven fabric 62, and a string 63 is passed through the annular insertion hole 64. The method for attaching the range hood filter 61 to the metal filter main body 41 and the exhaust port is described in the case of a range hood in which the string-shaped body 63 is loosened on the surface of the metal filter main body 41 removed from the exhaust port in the hood. After being covered with the filter 61, the string-shaped body 63 is pulled, so that the filter 61 on the surface side of the filter body 41 is tensioned.

However, in the range hood filter 50 as shown in FIG. 6, when the sheet-like non-woven fabric 51 is fixed to the filter main body 41 using a plurality of magnets 55, the sheet-like non-woven fabric 51 is formed. There is a problem that the filter body 41 hangs down and the appearance when attached is poor, and a gap is opened between the sheet-like nonwoven fabric 51 between the magnets 55 and the filter body 41, and the filter body 41 becomes dirty. When the magnet 55 has been used for a long time,
Oil fumes and the like are attached and become dirty, so that the hand becomes dirty when the sheet-like nonwoven fabric 51 is replaced, and the usability is poor. In addition, every time the range hood filter 50 is purchased, there is a problem in that the magnets accumulate and become obstructive or must be discarded. In addition, the filter body 4
When No. 1 was formed from a material without a magnet, the sheet-like nonwoven fabric 51 could not be attached.

When a fixing means such as a double-sided tape other than a magnet is used, when the sheet-like nonwoven fabric 51 is replaced,
The used sheet-like nonwoven fabric 51 remains attached to the fixing means, or the fixing means is
A large number remained along the peripheral edge of the surface of, and it was difficult to remove. Also, in the case of using any of the fixing means described above, when attaching the sheet-like nonwoven fabric 51 to the filter main body 41, it is necessary to arrange the fixing means on the filter main body 41 or the sheet-like nonwoven fabric 51, which is troublesome. .

In the range hood filter 61 as shown in FIG. 7, when the filter hood is attached to the filter main body 41, the back surface of the filter main body 41 is mostly covered with the filter 61. This is necessary and increases the cost. Also, this filter 61
Since the manufacturing process includes the step of forming the annular insertion hole 64 and the step of passing the string-shaped body 63 through the insertion hole 64, the number of steps is increased and the cost is increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and is easy to attach to a filter body detachably provided at an exhaust port in a hood of a range hood without using a magnet. An object is to provide a low-cost range hood filter that can be easily replaced.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a sheet-like filter for covering the surface of a rigid filter body which is detachably provided at an exhaust port in a hood of a range hood. A filter for a range hood made of a nonwoven fabric, wherein a bag-shaped locking portion is formed at least at both corners of one end in a length direction or a width direction of the sheet-shaped nonwoven fabric, and the bag-shaped locking portion is formed of the filter. The sheet-shaped nonwoven fabric has the other end in the length direction or width direction that is hooked at least at both corners of one end in the length direction or width direction of the main body. A range hood filter is characterized in that it has a length that can be wrapped around the back side of the end.

In the range hood filter according to the present invention, a bag-shaped engaging portion is formed at least at both corners of one end in the length direction or the width direction of the sheet-shaped nonwoven fabric. It is configured to be hooked on at least both corners of one end in the length direction or width direction of the filter body, and the other end in the length direction or width direction of the sheet-like nonwoven fabric is in the length direction or width direction of the filter body. The length of the filter body removed from the exhaust port in the hood in the length direction or the width direction when the filter body is attached to the filter body, because the filter body has a length that can be turned around to the back side of the other end. At least two corners of one end are covered with the bag-shaped locking portion of the range hood filter, and then the surface of the filter body is covered with the range hood filter. It can be attached by the other end of the direction or width direction Komu turn on the back side of the other end in the length direction or width direction of the filter body.

When the filter main body to which the range hood filter is mounted is attached to the exhaust port in the hood, the length of the filter main body in a state of being covered with the bag-shaped engaging portion of the range hood filter. After fitting one end in the direction or the width direction to the exhaust port, the other end in the length direction or the width direction of the filter body in a state where the other end of the range hood filter is turned toward the back side. It can be attached by fitting it into the exhaust port. When the range hood filter of the present invention becomes dirty and needs to be replaced, remove the other end in the length direction or the width direction of the filter body from the exhaust port while the range hood filter is attached, and then remove the bag. After removing one end in the length direction or width direction of the filter body covered with the hook-shaped locking portion from the exhaust port, the dirty range hood filter is removed from the filter body, and then the replacement range is removed. By installing the hood filter in the same manner as described above, the filter can be easily replaced.

According to the range hood filter of the present invention, when the filter body to which the range hood filter is attached is attached to the exhaust port in the hood, the bag-shaped engaging portion is connected to the length of the filter body as described above. The bag-shaped engaging portion is hooked on at least both corners of one end in the length direction or the width direction of the filter main body just by covering the one end in the width direction or the width direction, so that the positioning and the upper end of the range hood filter are performed. (One end in the length direction or the width direction) can be easily fixed. When the positioning and the upper end (one end in the length direction or the width direction) of the range hood filter are fixed to the filter body in this manner, the lower end (length or width direction) of the range hood filter is fixed. When the other end) is routed to the back side of the lower end (the other end in the length or width direction) of the filter body, there is no displacement of the upper end of the range hood filter, The lower end can be easily turned around the back side of the lower end of the filter body, and the lower end of the filter body with the lower end of the range hood filter turned around on the back side is connected to the exhaust port. When fitted, the lower end of the range hood filter is sandwiched between the filter body and the exhaust port (the other end of the range hood filter is pressed against the exhaust port by the filter body. ) It can be easily fixed since. When replacing the range hood filter,
Remove the filter main body from the exhaust port with the range hood filter attached, then remove the dirty range hood filter from the filter main body, and install the replacement range hood filter in the same manner as described above.

Further, since the range hood filter of the present invention can be attached to the filter body without using fixing means such as double-sided tape, the work of attaching and detaching to and from the filter body is simple, and replacement of the filter is easy. In this case, the problem that the used filter adheres and remains on the fixing means can be improved, and the fixing means does not remain on the surface of the filter body. Furthermore, the range hood filter of the present invention is such that when it is attached to the filter main body, only the both ends in the length or width direction of the filter (the upper end of the filter are bag-shaped locking portions) that wrap around to the back side. Therefore, compared to a conventional range hood filter in which a string is passed through an annular insertion hole provided in the nonwoven fabric, the material of the filter can be reduced, and the step of forming the bag-shaped locking portion is performed, for example, in a sheet-shaped nonwoven fabric. One end in the length direction or the width direction is bent to seal both ends in the width direction or the length direction by heat, or this sheet-like nonwoven fabric is placed on the back side of one end in the length direction or the width direction of the sheet-like nonwoven fabric. Can be easily manufactured by stacking the bag-shaped non-woven fabric for the locking portion separately provided and sealing the corners or both ends in the width direction and the length direction or both ends in the length direction and the width direction.

A large number of fixing means do not remain along the peripheral edge, and less fixing means remains on the surface of the filter body. Therefore, even in the range hood filter having such a configuration, without using a magnet, the range hood can be easily attached to a filter body detachably provided at an exhaust port in the hood, and can be easily replaced. A low-cost range hood filter can be provided.

In the filter for a range hood according to the present invention, the bag-shaped engaging portion is provided at one end in a length direction or a width direction of the sheet-shaped nonwoven fabric. The stopper may be configured to be hooked on one end in the length direction or the width direction of the filter body. In the range hood filter of the present invention having any one of the above structures, the other end in the length direction or the width direction of the sheet-like nonwoven fabric is the other end in the length direction or the width direction of the filter body. A fixing means such as a velcro tape or the like for stopping on the back side or the front side of the portion may be provided. When such a fixing means is provided, when attaching the range hood filter of the present invention to the filter body, the other end (lower end) in the length direction or width direction of the range hood filter is fixed. Since the filter body can be fixed to the back side or the front side of the filter body by the means, the work of attaching the filter body to which the filter for range hood is attached to the exhaust port can be performed more easily. Also, when this fixing means is provided on the back side of the filter body, it is less likely to become dirty than when it is provided on the front side,

[0037] Then, the state of the filter body 31 to the range hood filter 25 is mounted in mounting the exhaust port 30b in the hood 30a is covered with a bag-shaped locking portion 12 of the range hood filter 25 After fitting the upper end portion 31a of the filter body 31 into the exhaust port 30b,
The lower end 11b of the range hood filter 10 has a surface 31
The filter body 31 can be attached by fitting the lower end 31b of the filter body 31 attached to the c side to the exhaust port 30b. When the range hood filter 25 becomes dirty and needs to be replaced, the lower end portion 31 of the filter main body 31 remains in a state where the range hood filter 25 is attached.
b is removed from the exhaust port 30b, the upper end 31a of the filter body 31 covered with the bag-shaped engaging portion 12 is removed from the exhaust port 30b, and then the lower end 22b of the filter 25 is removed.
Is removed from the fixing means 15, and the dirty range hood filter 25 is removed from the filter body 31.
By attaching the replacement range hood filter 25 in the same manner as the attachment method described above, the replacement can be easily performed.

The range hood filter 25 of the present embodiment
In this case, the lower end 11b of the range hood filter 25 is attached to the surface of the lower end 31b of the filter main body 31 using fixing means 15 such as a Velcro tape. It is only necessary to provide at the lower end 31b of the filter main body, so that a large number of fixing means such as a double-sided tape do not remain along the peripheral edge of the filter main body at the time of replacement unlike the conventional range hood filter. The remaining fixing means can be reduced. Therefore, the range hood filter 2 of the present embodiment
5, the range hood 3 can be used without using a magnet.
The filter can be easily attached to the filter main body 31 which is detachably provided to the exhaust port 30b in the hood 30a, can be easily replaced, and can be reduced in cost.

In the above embodiment, the case where the range hood filter of the present invention is applied to the range hood filter that covers the vertically long filter body has been described. However, the range that covers the horizontally long (wide) type filter body is described. It can also be applied to hood filters. In the range hood filters of the first to third embodiments, the bag-shaped engaging portion is formed at one end (upper end) in the length direction of the sheet-shaped nonwoven fabric. The case where the stopper is hooked on at least both corners of one end (upper end) in the longitudinal direction of the filter body has been described. However, the bag-shaped engaging portion is one end in the width direction of the sheet-like nonwoven fabric. May be formed at least at both corners, and the bag-shaped locking portion may be hooked at least at both corners at one end in the width direction of the filter body. In the range hood filters of the first and second embodiments, the other end (lower end) in the length direction of the sheet-like nonwoven fabric is the other end (lower end) in the length direction of the filter body. The length of the sheet-shaped nonwoven fabric can be wrapped around the other end in the width direction of the filter main body. The length may be any suitable length.
