Abstract

<P>PROBLEM TO BE SOLVED: To provide a clean roll-type range hood cover for solving a problem that as a filter contaminated by oil and smoke is fixed in a state of being exposed in the rolled shape at a range hood ventilation port side, so that it has dirty and unsanitary look. <P>SOLUTION: Core members 3 are disposed on both ends of a band-shaped filter 2 to wind the filter, and stored in a pair of right and left covers 1a, 1b, the pair of covers 1a, 1b are expanded according to a width of a range hood ventilating hole, and the filter 2 is attached. A coagulating liquid 5 for preventing loosening is applied to slit-shaped opening sections 13a, 13b of the covers 1a, 1b to prevent loosening of the filter 2, and the contaminated filter is not fixed in a state of being exposed in the roll-shape, but stored in the cover 1b, thus the problem can be solved. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

      The present invention relates to a roll filter device for retrofitting to a kitchen range hood.

      The conventional roll filter is unsanitary in appearance because it is exposed even after the contaminated filter is wound up.

      As an improvement measure, oil cover can be prevented from falling around the range by using a cover that wraps the entire contaminated roll filter.

      The problem to be solved was troublesome when the filter contaminated with oil and smoke was changed, causing the filter to hang down and dirty around the hands and the range. The work of attaching a new filter to the ventilation opening also took time.

      In the conventional method, the contaminated filter is fixed in the form of a bare roll on the side of the range hood ventilation port, which has a disadvantage that is unclean and unsanitary. Therefore, an object of the present invention is to provide a clean range hood cover to solve these drawbacks.

      In the present invention, a core member is wound around both ends of a belt-like filter with a predetermined interval, housed in a pair of left and right covers, and a pair of covers are spread out according to the width of the range hood ventilation port. Tighten up. The anti-sagging of the filter was provided by applying the anti-sagging coagulation liquid to the slit-shaped opening of the cover. By storing the dirty filter in the cover, the oil sag was prevented from falling around the range, and the dirty filter was also removed in a roll and not fixed and stored in the cover.

      The present invention is as described above, and when a filter to which oil or smoke has adhered has passed, if it is left in a roll shape, it will become oily and become unclean. By storing in the cover of the present invention, an effect of preventing oil dripping from falling around the range is provided.

      The present invention has an effect that the surroundings of the kitchen and the ventilation port can be kept beautiful if the cover surface is brightly printed or the like, without being exposed to the roll side of the range while being dirty and being exposed.

Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an overall perspective view of the present invention,
2 is a front view and the structure of the core member 3, the anti-loosening coagulating liquid 5 and the coating unit 6. FIG. 3 is an enlarged cross-sectional view of the cover. It is constituted by a core member 3 that applies a slack-preventing coagulating liquid 5 to the openings 13a and 13b and maintains the filter 2 tightly.

The core member 3 is a paper tube having a diameter of 10 mm, and the core member 3 is wound around the pair of left and right core members 3 with a predetermined distance therebetween by bonding both side portions of the band-like filter 2.

      FIG. 4 is a cutaway view of the cover 1, 5 is applied to the slit opening slack preventing coagulation liquid application portion 6, the fold line 10 is folded inward, and a thick paper adhesive is applied to the bonding margin portion 11a to the side plate portion 8a. Bond and mold the cover.

      The core member 3 is inserted into the insertion port 9a through the core member 3 and the filter 2 from the unbonded portion direction of the side plate portion 8b, and the core member 3 is projected by 2 cm. Insert into the protruding portion 9b. The core member 3 is projected by 2 cm, and the side plate portion 8b is bonded to the cover bonding margin 11b with a thick paper adhesive. One cover 1b is formed in the same manner as described above.

      By inserting and fixing the operation shooting cap 7 at four 2 cm protruding portions of the core member 3, it is possible to prevent the filter from being unwound and unwound.

      Three magnets 3 are bonded at equal intervals as fixing means to the ventilation port mounting surfaces 12 of the pair of covers 1a and 1b. An arcuate winding direction diagram 14 is shown on the side plate portions 8a and 8b of the filter winding photographing cap 7. FIG.

      As shown in Fig. 6, the cover 1a and 1b are fitted with a filter 2 stored in the width of the ventilation opening of the range hood body 15. The contamination of the range hood ventilation opening is suppressed as much as possible, and the dirty filter can be replaced. Rotate the cap 7 in the direction shown in Fig. 5 to unwind the dirty surface, expose the new surface, filter the end of filter winding, write a red line on the front of the filter about 50cm and notify the remaining amount. Can be prevented.
