Description

[Technical field]

[0001] The present invention relates to a mounting fixture used when mounting a nonwoven fabric filter to a range hood with a baffle vane, and more particularly to a mounting fixture that allows a nonwoven fabric filter to be easily mounted to a range hood with a baffle vane at home. [Background technology]

[0002] There are two types of range hoods used in home kitchens: deep range hoods and range hoods with baffles, but in recent years, the latter type has become more common. The reason for this is that range hoods with baffles have baffles that are roughly parallel to the ceiling surface, giving them a flat design that gives a clean look, and the air intake is wide and allows for efficient intake of oily smoke. In order to prevent the baffles and metal filters inside the range hood from being soiled by oily smoke, a nonwoven fabric filter is attached with an adhesive to cover the baffles and the air intake (Patent Document 1). Specifically, a nonwoven fabric filter is used in which an adhesive layer is applied to one side of the nonwoven fabric filter and a release sheet is attached to the adhesive layer (Patent Document 1, paragraph 0002).

[0003] The specific procedure for mounting and attaching such an adhesive nonwoven fabric filter so as to cover the straightening plate and the air intake is as follows. First, the release sheet is removed from the adhesive nonwoven fabric filter. Then, the nonwoven fabric filter is held by fingers at both ends and stretched, lifted up to the vicinity of the ceiling surface, and the adhesive layer is pressed against the surface of the straightening plate or the range hood frame to mount it. However, the nonwoven fabric filter used in the range hood with the straightening plate is large, about 60 to 65 cm wide and about 60 to 90 cm long, and is coarse, bulky, and has low bending resistance and is flexible, making such a task difficult. That is, it is not easy to remove the release sheet, it is not easy to hold both ends of the nonwoven fabric filter by fingers and stretch it, it is not easy to lift it up to the vicinity of the ceiling surface in a stretched state, and it is not easy to press the entire nonwoven fabric filter uniformly against the ceiling surface. In addition, due to their large size, when the adhesive strength of the adhesive layer is reduced due to the effects of oily smoke, the nonwoven fabric filters tend to come off.

[0004] [Patent Document 1] JP 2023-163609 A Summary of the Invention [Problem to be solved by the invention]

[0005] An object of the present invention is to provide a mounting fixture that can easily attach and secure a nonwoven fabric filter to a range hood with a baffle plate. [Means for solving the problem]

[0006] The present invention solves the above problem by using a fixture having a permanent magnet to maintain a large-sized nonwoven fabric filter in an extended state, and by using the permanent magnet to attach the nonwoven fabric filter to a range hood frame. That is, the present invention provides a pair of fixtures 10 capable of holding the left and right ends of a nonwoven fabric filter in an extended state by sandwiching the left and right ends of the nonwoven fabric filter for covering a straightening plate provided substantially parallel to a ceiling surface, the fixtures 10 having a central portion 3, a first portion 1 overlapping above the central portion 3, and a second portion 2 overlapping below the central portion 3, the fixtures 10 having a first permanent magnet 1a provided near the upper side of the first portion 1 and a first permanent magnet 1b provided near the lower side of the first portion 1, a second permanent magnet 2c provided near the upper side of the second portion 2 and a second permanent magnet 2d provided near the lower side of the second portion 2. the central portion 3 is provided with a metal body 3a provided at a position matching with the first permanent magnet 1a and a metal body 3b provided at a position matching with the first permanent magnet 1b when the central portion 3 and the first portion 1 are superimposed, and a metal body 3c provided at a position matching with the second permanent magnet 2c and a metal body 3d provided at a position matching with the second permanent magnet 2d when the central portion 3 and the second portion 2 are superimposed.

[0007] The material of the mounting fixture 10 according to the present invention may be any material such as synthetic resin, metal, or wood, but is generally preferably synthetic resin. The shape of the mounting fixture 10 may be any, but the inner surface (the surface where the nonwoven fabric filter is sandwiched) is preferably trough-shaped. The schematic plan view of the inner surface of the mounting fixture 10 is shown in FIG. 1. The mounting fixture 10 is composed of three parts, a first part 1, a central part 3, and a second part 2. A first permanent magnet 1a is provided near the upper side of the first part 1. Specifically, the first permanent magnet 1a may be fixed to the inner surface of the trough-shaped first part 1 by any means. For example, a claw may be provided on the inner surface of the trough, and the first permanent magnet 1a may be engaged with the claw. The back surface of the first permanent magnet 1a may be fixed to the inner surface of the trough by adhesive. A first permanent magnet 1b is provided near the lower side of the first part 1. The first permanent magnet 1b is also fixed by the same means as the first permanent magnet 1a. A plurality of protrusions on which a nonwoven fabric filter can be hooked may be provided between the first permanent magnet 1a and the first permanent magnet 1b. Specifically, a plurality of protrusions may be arranged in a straight line in the longitudinal direction of the first section 1. The second section 2 has the same configuration as the first section 1, with a second permanent magnet 2c provided near the upper side and a second permanent magnet 2d provided near the lower side. Similarly to the first section 1, the second section 2 may also have a plurality of protrusions on which a nonwoven fabric filter can be hooked between the second permanent magnet 2c and the second permanent magnet 2d.

[0008] Metal bodies 3b, 3a, 3d, and 3c are provided on the inner surface of the central region 3. These metal bodies may be fixed to the inner surface of the gutter-shaped shape by the same means as the first permanent magnet 1a. As with the first region 1 and the second region 2, a plurality of protrusions may be provided between the metal bodies 3b, 3a, 3d, and 3c on which a nonwoven fabric filter can be hooked. The inner surface of the central region 3 overlaps with the inner surface of the first region 1 and the inner surface of the second region 2. When overlapped, the metal body 3b matches the first permanent magnet 1b, the metal body 3a matches the first permanent magnet 1a, the metal body 3c matches the second permanent magnet 2c, and the metal body 3d matches the second permanent magnet 2d. It is preferable that the central region 3 is connected to the first region 1 and the second region 2 by the foldable parts 4a and 4b. This is because the first region 1 and the second region 2 can be folded to overlap with the inner surface of the central region 3. It is preferable that the bendable parts 4a, 4b are integral with the first part 1, the central part 3, and the second part 2, and are molded at once using synthetic resin. It is also possible to attach the bendable parts 4a, 4b as separate parts from the first part 1, the central part 3, and the second part 2. Furthermore, the central part 3 may be divided from the first part 1 and the second part 2 without being connected by the bendable parts 4a, 4b. In this case, the three parts are separated, but the central part 3 may be overlapped with the first part 1 and the second part 2 so that the first permanent magnet 1a, etc. and the metal body 3a, etc. match. In addition, the central part 3 may also be divided at the center into a part including the metal bodies 3a and 3b and a part including the metal bodies 3d and 3c. Then, the two parts may be fitted together and connected when in use.

[0009] In the above embodiment, permanent magnets are provided in the first region 1 and the second region 2, but all four metal bodies provided in the central region 3 may be replaced with permanent magnets. In this case, the force that clamps the nonwoven fabric filter is increased, and the nonwoven fabric filter can be well maintained in an expanded state. On the other hand, it tends to be difficult to separate the central region 3 from the first region 1 and the second region 2 with fingers. In general, when the metal body in the central region 3 is a permanent magnet, it is preferable to replace the corresponding permanent magnet in the first region 1 or the second region 2 with a metal body.

[0010] The length of the central portion 3 is approximately the same as the width of the nonwoven fabric filter, about 60 to 65 cm. The left end of the nonwoven fabric filter 5 is placed on the inner surface of the central portion 3, and the first portion 1 and the second portion 2 are overlapped to hold the left end of the nonwoven fabric filter 5 in a stretched state in the width direction by the magnetic force of the permanent magnet. The right end of the nonwoven fabric filter 5 is similarly held in a stretched state in the width direction by holding the right end. This is illustrated in Figs. 2 and 3. Fig. 2 is a schematic plan view, Fig. 3 is a schematic bottom view, and Fig. 4 is a schematic left side view. The nonwoven fabric filter 5 is then maintained in such a stretched state, lifted toward the ceiling surface 8, and covered with the straightening plate 6 and the air intake 9, and attached to the metal frame of the range hood by the permanent magnets provided on the mounting fixture 10. When the permanent magnets are provided at the first portion 1 and the second portion 2, they are attached so that the surface shown in FIG. 2 faces the straightening plate (FIG. 5). When the permanent magnets are provided at the center portion 3, they are attached so that the surface shown in FIG. 3 faces the straightening plate. The former is preferable because the center portions of the left and right ends of the nonwoven fabric filter 5 are less likely to bend due to gravity and the appearance is neater. The pair of mounting fixtures 10 and the nonwoven fabric filter 5 are preferably combined and sold as a filter kit for a range hood with a straightening plate. Effect of the Invention

[0011] By using the mounting fixture according to the present invention, even a large-sized nonwoven fabric filter can be maintained in a stretched state at both ends by the action of the permanent magnets, and can be attached to the metal frame of a range hood with a baffle vane by the action of the permanent magnets, thus achieving the effect of easily attaching the nonwoven fabric filter to a range hood with a baffle vane.
