BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a range hood which is disposed above a cooking gas range to discharge smoke, and is a filter device attached to the range hood, particularly a filter suitable for a deep range hood. It relates to the device.

[0002]

2. Description of the Related Art Heretofore, in kitchens of restaurants as well as kitchens of general households, range hoods provided with exhaust fans have been widely adopted in order to discharge oil smoke and odors generated during cooking. A filter material is attached to the intake port of the range hood to prevent oil smoke from adhering to the exhaust fan.

In the deep range hood, the hood itself is formed in a large size in order to exhaust a wide range of smoke, and the depth and width dimensions of the hood are taken into consideration in consideration of harmony with the design of the system kitchen or the like. However, the filter material attached to such a range hood needs to have a structure that can be adapted to the range hood.

Therefore, recently, as shown in FIG. 8, a bellows-shaped attachment piece B is provided at both left and right ends of a horizontally long rectangular filter material A, and the length of the attachment piece B is set to the inner dimension of the hood. It was devised to be adapted to.

[0005]

However, according to the filter material A as described above, since the expansion and contraction width of the mounting piece B is comparatively small, the range width of the range hood which can be adapted is limited and the range of use is narrow. Not only that, even if the mounting piece B is extended and mounted, a gap is created between both ends of the filter material and the inner surfaces of the range hood facing each other, so that there is a problem that the filter action cannot be exerted.

Such a problem can be solved by stacking two filter materials on each other and connecting the filter materials so as to be able to expand and contract in the left-right direction. However, the filter material A has an inverted trapezoidal cross section around the filter portion D. Since it has a structure in which the aluminum foil frame C having the reinforcing groove portion E is integrally attached,
When they are overlapped with each other, a gap corresponding to the depth of the reinforcing groove E is formed between the edges of the frame bodies of both the filter materials A and A, and it is difficult to attach them to the overlapped portions with the clip-shaped connecting tool known from the related art. In addition to the above, there is a problem that stable connection cannot be performed.

[0007]

The present invention has been made in view of the above problems, and the reinforcing groove portion 4 is provided over the entire circumference.
And a filter material 1 formed by integrally mounting a frame body 3 made of aluminum foil on which an edge winding portion 7 is formed on an outer end edge of the groove portion 4 to a peripheral edge of a filter portion 2 made of a non-woven fabric, and a C-shaped cross section. The clip body 8 is formed by forming one free end of the main body 8a as an engaging end 8b and bending the other free end in the extension direction of the one free end to form a pressing piece 8c. In the upper and lower frame portions 3a and 3b of the frame body 3 in the overlapping portion, the two material materials 1 and 1 are overlapped with each other, and the engaging end 8b of the clip body 8 is curled around the frame body 3 in one of the filter materials 1. The inside of the part 7 is locked and the pressing piece 8c
Is elastically contacted with the inner surface of the reinforcing groove portion 4 of the other filter material 1 and the upper and lower frame portions 3 are formed by these upper and lower clip bodies 8, 8.
It is intended to provide a range hood filter device having a structure in which a and 3b are slidably sandwiched in the left-right direction .

[0008]

In the stacked filter materials 1, 1, the engaging end 8b of the clip body 8 is brought into contact with and locked to the inside of the edge winding portion 7 of the frame body 3 of one of the filter materials 1, and then the locking is performed. The pressing piece that is free from the engaging end 8b with the portion as a fulcrum
If the end side having 8c is moved over the outer peripheral edges of the frame bodies of the two filter materials 1 and 1, the pressing piece 8c elastically contacts the reinforcing groove portion 4 of the other filter material 1 and the clip body is formed. The filter body 1, 1 is horizontally slidably connected by the clip body 8 in a state where the frame body edge winding portions 7, 7 of the both filter materials 1, 1 are included in the main body portion 8a. .

The upper and lower frame portions 3a, 3b of both filter materials 1, 1 are elastically sandwiched by the clip body 8, and the engaging end 8b of the clip body 8 and the pressing piece 8c are one filter material 1.
Since they are engaged with the inner side of the winding edge and the reinforcing groove portion of the other filter material 1, the two filter materials 1, 1 accurately slide relative to each other in the horizontal direction via the clip body 8. , It is possible to easily adjust the length to fit the width of the intake port of the range hood with high accuracy.
