DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holding frame for a filter for a range hood to be attached to a kitchen or the like at home.

[0002]

2. Description of the Related Art A range hood with a built-in ventilation fan is used as a means for discharging air containing oil generated in a kitchen. This range hood is generally mounted on a lower surface of the range hood opening above the range so that a filter, which is a member capturing air oil, can be detachably mounted. It has been removed from the hood and cleaned. The above filter, in the holding frame,
A filter body such as a laminate of fine ultra-flame-retardant glass fibers or a fine mesh wire mesh is detachably attached.

[0003] Incidentally, since oil adheres to the filter of the range hood, cleaning the filter in a general household or the like requires a great deal of labor and labor, is complicated, and it is difficult to completely remove the oil. It is. So, in recent years,
More and more homes have contracts with professionals to periodically replace disposable filter bodies. These professionals employ standardized aluminum holding frames instead of dedicated filter holding frames previously mounted by each range hood manufacturer in order to unify the filter specifications. An operator carries this standardized holding frame to each home, removes a dirty dedicated filter, and replaces the filter with a new replacement filter using the holding frame. However, the range hood filter holding frame has different specifications depending on the manufacturer, and generally has substantially the same width dimension, but has various depth dimensions. In some cases, the shapes of the filter mounting opening edges do not match, and in this case, a gap is generated between the holding frame and the filter mounting opening edge.

Conventionally, as shown in FIGS. 11 to 14, an adjuster panel (2) is attached to one side edge of the holding frame (1) in the depth direction as shown by a dashed line, thereby making each manufacturing method. It was the same size as the filter holding frames of the various range hoods of the manufacturer. A plurality of types of adjuster panels (2) having different widths in the depth direction at a constant pitch are prepared.

Conventionally, the holding frame (1) has an L-shaped cross member (3) (3) and longitudinal members (4) (4) butted at opposite ends thereof at right angles, and the butted portion is formed. Are fixed with an L-shaped connecting member (5) to form a slightly elongated rectangular frame. A part of each connecting member (5) has a rear side of the holding frame (1). A locking piece (8) for locking a holding member (7) for holding a filter body (6) such as a laminated body of glass fibers disposed on the filter member is bent and formed to face in the depth direction. At the same time, both ends of a predetermined length of wire members (9) (9) arranged diagonally are fixed to the respective corner portions on the front surface of the butted portion.

The holding member (7) is formed by combining wire materials in a frame shape, and bridges the horizontal wire materials (12) and (12) at the end in the depth direction of the rectangular outer circumferential wire material (11). A plurality of vertical wire members (13) are bridged between the horizontal wire materials (12) and (12) on both the left and right sides and in the center, and the vicinity of a corner of the outer peripheral wire material (11) is held by a holding frame (1). The holding member (7) is detachably attached to the holding frame (1) by being locked to each of the locking pieces (8).

[0007] Projections (16) and (16) are protrudingly provided at the symmetrical portions on both front sides of one edge of the holding frame (1) in the depth direction, and the projections (16) and (16) are held. The mounting groove (19a) (19) is formed so that the edge of the holding frame (1) in the depth direction faces the depth of the filter mounting opening edge of the range hood (18).
b) Removably mount on b).

A procedure for attaching a replacement filter to a range hood of each household using the holding frame (1) having the above structure will be described.

An operator visits each home, removes a dirty filter from the range hood (18), and then installs a new replacement filter. At this time, the filter on the range hood (18) side is longer than the holding frame of the replacement filter, and the holding frame (1) and the range hood (18) are arranged in the depth direction.
If there is a gap between the filter mounting opening edge and the filter mounting opening edge of the range hood, the operator measures the depth dimension of the filter mounting opening edge of the range hood, and adjusts the depth direction of the holding frame (1) so that the measured depth dimension is obtained. An adjuster panel (2) having a width corresponding to the gap is selected from a plurality of adjuster panels and attached to one side edge of the adjuster panel. As shown in FIG. 15, the adjuster panel (2) has a U-shaped cross section (22) of the adjuster panel (2) fitted to a rising wall (21) at the edge in the depth direction of the holding frame (1). Then, the rising wall (21) and the U-shaped section (22) are caulked with a caulking tool to be connected and fixed to the holding frame (1).

When the adjuster panel (2) is attached to the holding frame (1) in this manner, as shown in FIG. 16, the holding frame (1)
Of the range hood (18) into one mounting groove (19
After fitting into a), the outer edge of the adjuster panel (2) is fitted into the other mounting groove (19b).

[0011]

Conventionally, according to the range hood filter holding frame (1), the depth dimension of the filter mounting opening edge of the range hood of each household is larger than the depth dimension of the holding frame (1). The operator measures the depth dimension of the filter mounting opening edge at the site of each home, selects a desired adjuster panel (2) so as to have the depth dimension, and selects one end of the holding frame (1). The crimping tool had to be fixed to the edge with a crimping tool, and the operation was extremely complicated.

Further, once the adjuster panel (2) is fixed to the holding frame (1), it cannot be easily removed, so that the size of the holding frame (1) with the adjuster panel (2) in each home varies. Since it becomes an exclusive product for each household, it is very troublesome to collect and clean it and reuse it for a range hood in the same household. In addition, since the holding frame (1) is made of aluminum and has inferior strength and chemical resistance, it is difficult to wash a large amount at once with a washing machine or the like. It is necessary to manually wipe off the oil and the like adhering to the surface of the holding frame.
For this reason, there has been a problem that the wiping operation of the oil requires a great deal of labor and labor, and the working efficiency is extremely poor.

Further, mounting grooves (19a) (1) of the range hood (18) of the holding frame (1) and the adjuster panel (2).
At the time of fitting to 9b), a gap (23) is generated in the mounting groove (19a), and air containing oil flows through the gap (23), so that the oil is completely removed by the filter body (6). Unable to catch, ventilation fan becomes dirty with oil, and holding frame (1)
There was a problem of rattling.

The present invention has been proposed in view of the above-mentioned problems, and is commonly and one-touch detachably mountable to range hoods having different specifications, and is suitable for large-scale batch cleaning after unitary recovery. It is still another object of the present invention to provide a range hood filter holding frame having high adhesion to a filter mounting opening edge.

[0015]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a frame formed in a square shape, and inner and outer sides along a plane of the frame at one side edge of the frame. a filter mounting opening edge of hood a slidable in a direction
An adjuster panel for closing a gap formed between the adjuster panel and one end fixed to the adjuster panel and
Press the adjuster panel against the frame to open the filter
And an elastic body relatively biased toward the edge . The frame and the adjuster panel are separable from each other, and may be made of stainless steel.

[0016]

When mounting the holding frame on the range hood of each home, the operator manually pushes one side edge of the holding frame into one of the mounting grooves of the mounting opening edge of the range hood while holding down the adjuster panel. When the adjuster panel is released from the frame due to the biasing force of the elastic body after being pushed in against the biasing force of the elastic body and released from the adjuster panel, the filter mounting opening edge of the range hood is And the holding frame is mounted on the filter mounting opening edge of the range hood.
