Abstract
Description
Technical Field
[0001] The present invention relates to a fixture used when attaching a non-woven fabric filter to a range hood with a baffle plate, and more particularly to a fixture that can easily attach a non-woven fabric filter to a range hood with a baffle plate in a household.
Background Art
[0002] Range hoods used in household kitchens include deep-type range hoods and range hoods with baffle plates. In recent years, the latter type of range hood has become the mainstay. The reasons are that the range hood with a baffle plate has a baffle plate that is substantially parallel to the ceiling surface, has a flat design and a clean appearance, and has a wide air intake that can efficiently suck in oil fumes. To prevent the baffle plate of this range hood and the metal filter inside the range hood from being soiled by oil fumes, a non-woven fabric filter is attached with an adhesive so as to cover the baffle plate and the air intake (Patent Document 1). Specifically, an adhesive layer is applied to one side of the non-woven fabric filter, and a release sheet is pasted on the adhesive layer (Patent Document 1, paragraph 0002).
[0003] The specific procedure for installing such an adhesive nonwoven fabric filter so as to cover the baffle plate and air intake is as follows: First, remove the release sheet from the adhesive nonwoven fabric filter. Then, grasp both ends of the nonwoven fabric filter with your fingers and lift it up to near the ceiling surface, pressing the adhesive layer against the surface of the baffle plate and the range hood frame to install it. However, the nonwoven fabric filters used in range hoods with baffle plates are large, measuring about 60-65 cm in width and 60-90 cm in length, and are also coarse, bulky, and flexible with low rigidity, making this work difficult. In other words, it is not easy to remove the release sheet, nor is it easy to grasp both ends of the nonwoven fabric filter with your fingers and stretch it, nor is it easy to lift it up to near the ceiling surface in a stretched state, nor is it easy to evenly press the entire nonwoven fabric filter towards the ceiling surface. Furthermore, due to its large size, the non-woven fabric filter could easily detach if the adhesive layer's stickiness decreased due to the effects of oil fumes.
[0004] [Patent Document 1] Japanese Patent Publication No. 2023-163609 [Overview of the project] [Problems that the invention aims to solve]
[0005] The object of the present invention is to provide a mounting device that allows a nonwoven fabric filter to be easily attached to a range hood with a baffle plate. [Means for solving the problem]
[0006] The present invention solves the above problem by maintaining a large nonwoven fabric filter in an extended state with a mounting fixture having permanent magnets, and by attaching the nonwoven fabric filter to the range hood frame with these permanent magnets. Specifically, the present invention provides a pair of mounting fixtures 10 that can maintain the left and right ends of a nonwoven fabric filter, which covers a rectifier plate provided substantially parallel to the ceiling surface, in an extended state by clamping the left and right ends of the filter. The mounting fixture 10 has a central part 3, a first part 1 that overlaps above the central part 3, and a second part 2 that overlaps below the central part 3. It comprises a first permanent magnet 1a provided near the upper edge of the first part 1 and a first permanent magnet 1b provided near the lower edge of the first part 1, and a second permanent magnet 2c provided near the upper edge of the second part 2 and the lower edge of the second part 2 The present invention relates to a filter mounting device for a range hood with a rectifier plate, characterized in that it comprises a second permanent magnet 2d provided in the vicinity of the center portion 3, and the central portion 3 is provided with a metal body 3a at a location that coincides with the first permanent magnet 1a when the central portion 3 and the first portion 1 are superimposed, and a metal body 3b at a location that coincides with the first permanent magnet 1b, and the central portion 3 is provided with a metal body 3c at a location that coincides with the second permanent magnet 2c when the central portion 3 and the second portion 2 are superimposed, and a metal body 3d at a location that coincides with the second permanent magnet 2d.
[0007] The mounting fixture 10 according to the present invention can be made of any material such as synthetic resin, metal, or wood, but is generally made of synthetic resin. Its shape is arbitrary, but it is preferable that the inner surface (the surface on which the nonwoven fabric filter is sandwiched) is trough-shaped. A schematic plan view of the inner surface of the mounting fixture 10 is shown in Figure 1. The mounting fixture 10 consists 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 edge of the first part 1. Specifically, the first permanent magnet 1a can be fixed to the trough-shaped inner surface of the first part 1 by any means. For example, a claw can be provided on the trough-shaped inner surface, and the first permanent magnet 1a can be locked to this claw. Alternatively, the back surface of the first permanent magnet 1a may be fixed to the trough-shaped inner surface with an adhesive. A first permanent magnet 1b is provided near the lower edge of the first part 1. The first permanent magnet 1b is also fixed by the same means as the first permanent magnet 1a. Multiple protrusions for attaching a nonwoven fabric filter may be provided between the first permanent magnet 1a and the first permanent magnet 1b. Specifically, multiple protrusions can be arranged in a straight line along the longitudinal direction of the first part 1. The second part 2 has the same configuration as the first part 1, with a second permanent magnet 2c near the inner edge of the upper part and a second permanent magnet 2d near the inner edge of the lower part. In addition, the second part 2 may also have multiple protrusions for attaching a nonwoven fabric filter between the second permanent magnet 2c and the second permanent magnet 2d, similar to the first part 1.
[0008] Metal bodies 3b, 3a, 3d, and 3c are provided on the inner surface of the central part 3. These metal bodies can also be fixed to the trough-shaped inner surface by the same means as the first permanent magnet 1a. In addition, as with the first part 1 and the second part 2, multiple protrusions can be provided between the metal bodies 3b, 3a, 3d, and 3c to which a nonwoven fabric filter can be hooked. The inner surface of the central part 3 overlaps with the inner surfaces of the first part 1 and the second part 2. When they overlap, metal body 3b matches the first permanent magnet 1b, metal body 3a matches the first permanent magnet 1a, metal body 3c matches the second permanent magnet 2c, and metal body 3d matches the second permanent magnet 2d. It is preferable that the central part 3 and the first part 1 and the second part 2 are connected by bendable parts 4a and 4b. This is because the first part 1 and the second part 2 can overlap with the inner surface of the central part 3 by folding them. The foldable parts 4a and 4b are preferably formed as a single unit with the first part 1, the central part 3, and the second part 2, using synthetic resin. Alternatively, the foldable parts 4a and 4b can be attached separately from the first part 1, the central part 3, and the second part 2. Furthermore, the central part 3 and the first part 1 and the second part 2 may not be connected by the foldable parts 4a and 4b, but may be separated. In this case, the three parts will be separate, but the central part 3 and the first part 1 and the second part 2 can be superimposed so that the first permanent magnet 1a and the metal body 3a match. The central part 3 may also be divided in the middle into a part containing metal bodies 3a and 3b and a part containing metal bodies 3d and 3c. The two parts can then be fitted together and joined during use.
[0009] In the above-described embodiment, permanent magnets are provided in the first part 1 and the second part 2, but all four metal bodies provided in the central part 3 may be replaced with permanent magnets. In this case, the force holding the nonwoven fabric filter will be stronger, and the tension of the nonwoven fabric filter can be maintained well. On the other hand, it will become more difficult to separate the central part 3 from the first part 1 and the second part 2 with your fingers. Generally, when the metal bodies in the central part 3 are replaced with permanent magnets, it is preferable to replace the corresponding permanent magnets in the first part 1 or the second part 2 with metal bodies.
[0010] The length of the central section 3 is approximately the same as the width of the nonwoven fabric filter, about 60-65 cm. The left end of the nonwoven fabric filter 5 is placed on the inner surface of this central section 3, and the first section 1 and the second section 2 are overlapped so that the left end of the nonwoven fabric filter 5 is held in place by the magnetic force of the permanent magnet and maintained in a taut state in the width direction. The right end of the nonwoven fabric filter 5 is similarly held in place and maintained in a taut state in the width direction. This is illustrated in Figures 2 and 3. Figure 2 is a schematic plan view, Figure 3 is a schematic bottom view, and Figure 4 is a schematic left side view. The nonwoven fabric filter 5 is then maintained in this taut state, lifted towards the ceiling surface 8 so as to cover the rectifier plate 6 and the air intake 9, and attached to the metal frame of the range hood by the permanent magnet provided on the mounting fixture 10. If permanent magnets are provided in the first section 1 and the second section 2, they should be mounted so that the surface shown in Figure 2 faces the rectifier plate (Figure 5). If permanent magnets are provided in the central section 3, they should be mounted so that the surface shown in Figure 3 faces the rectifier plate. The former is preferable because the central 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. It is preferable to sell the pair of mounting brackets 10 and the nonwoven fabric filter 5 together as a filter kit for range hoods with rectifier plates. [Effects of the Invention]
[0011] Using the mounting device according to the present invention, even large nonwoven fabric filters can be kept taut at both ends by the action of permanent magnets, and can be attached to the metal frame of a range hood with a baffle plate by the action of the permanent magnets. Therefore, it has the effect of making it easy to attach nonwoven fabric filters to range hoods with baffle plates. [Brief explanation of the drawing]
