DETAILED DESCRIPTION OF THE INVENTION
An embodiment of a filter device for a range hood according to the present invention will be described below with reference to FIGS. First, FIG. 1 (a) is a perspective view of a mounting frame (1) of a hood filter device for a range according to the present invention. In FIG. 1 (a), (2) is a bowl-shaped connecting plate, and (3) is a corner plate. is there.
[0009]
As shown in FIG. 1 (b), the hook-shaped connecting plate (2) has a guide plate (2 b) and a slide groove portion (inward opening) on both side edges along the longitudinal direction of the long flat plate material (2 a). 2c) are opposed to each other and are integrally formed in a bowl shape. The corner plate (3) has a side plate (3b) planted and fixed along the outer edge of the L-shaped flat plate material (3a). As shown in FIGS. 1 (a) and 1 (c), the side plate (3b) ) Is slidably engaged with the guide plate (2b) of the connecting plate (2) and the inner edge (3c) of the L-shaped flat plate (3a) is slidably fitted into the slide groove (2c). Connected to the connecting plate (2).
[0010]
The operation of the present invention will now be described based on the above configuration. First, the mounting frame (1) of the filter device for the range hood according to the present invention has four corner plates (3) arranged in a square shape as shown in FIG. As shown, the side plate (3b) is slidably contacted with the guide plate (2b) and guided while the inner edge of the flat plate (3a) is slidably fitted into the slide groove (2c). Are connected by four connecting plates (2) to form a square frame.
[0011]
Then, it becomes possible to arbitrarily change the frame size by sliding the corner plate (3)... With the connecting plate (2). It can be used immediately by simply changing the frame size of the filter device, and the filter material may be attached to the mounting frame (1) as appropriate.
[0012]
Next, another embodiment of the present invention shown in FIGS. 2 (a) to 2 (d) is obtained by adding a clip member (4) to the above configuration, as shown in FIGS. 2 (a) to (c). Further, the corner plate (3) and the connecting plate (2) are fixed by sandwiching the guide plate (2b) and the side plate (3b) with the clip member (4). The clip member (4) shown in FIGS. 2 (a) to 2 (c) is mounted with a filter member presser fixing wire member (5) described later by bending the inner lower end of the clip portion (4a) upward. In addition, as shown in FIG.2 (d), the clip member (6) which consists only of a clip part may be sufficient.
[0013]
3 (a), 3 (b) and 4 (a), 4 (b), the above-described metal wire member (5) for fixing the filter material presser that can be deformed to the clip member (4). ) And wire members (5a) to (5d) having different shapes are shown for each figure.
[0014]
First, the wire member (5a) shown in FIG. 3 (a) is obtained by connecting one end of each of a pair of L-shaped wires (5ab) to both ends of the bending wire (5aa). Then, after each corner plate (3) is slid back and forth, left and right to set the rectangular frame size according to the filter material size, two clip members are provided along the L-shape at each corner of the mounting frame (1). (4).. Are sandwiched to fix the corner plate (3).
[0015]
Next, after storing the filter material (not shown) in the mounting frame (1), the bent wires (5aa) and (5aa) of the two wire members (5a) and (5a) are stretched and deformed according to the mounting frame dimensions. Each L-shaped wire (5ab) (5ab) is housed in the holding portion (4b) of the clip member (4). Then, while partially bending the bent wires (5aa) (5aa), the wire members (5a) (5a) are held by the clip members (4), and the filter material is pressed and fixed.
[0016]
Further, the wire member (5b) shown in FIG. 3 (b) deforms the above-described wire member (5a), and the central portion (5bb) of the bent wire (5ba) is wound to form an L-shaped wire (5bc). The U-shaped holding part (5bd) is bent into a U shape, and is held by the clip member (4) at the U-shaped intermediate part (M) so that the U-shaped side parts (S) and (S) are made of the filter material. Used to fix the presser foot.
[0017]
The wire member (5c) shown in FIG. 4 (a) is freely stretchable and deformable by extending the holding wires (5cc) (5cc) along the outer sides of the opposite sides (5cb) (5cb) of the Z-shaped wire (5ca). The holding wire (5cc) is accommodated in the clip member (4) to hold the wire member (5c), and the Z shape is used for fixing the filter material.
[0018]
Further, the wire member (5d) shown in FIG. 4 (b) has a holding wire at the opposite side (5db) of the Z-shaped wire (5da), and the presser fixing portion (5dc) is extended and formed along the inside thereof so as to be freely stretchable and deformable. The two wire members (5d) and (5d) are overlapped in the X shape at the intermediate portion, the holding wire (5db) is stored in the clip member (4), and the wire member (5d) is held. The shape is used for fixing the filter material presser.
[0019]
【The invention's effect】
According to the present invention, in the filter device for a range hood, the attachment frame of the filter material is formed to be extendable in the front and rear, left and right directions so that it can be changed to any size and shape. Can be freely expanded and contracted as appropriate, and can be immediately set to an appropriate dimension, so that it is not necessary to replace the mounting frame and the cost can be reduced.
