Problems solved by technology

This non-woven fabric filter, because the mesh will be clogged due to the oil fume and dust collected from the exhaust gas, resulting in increased ventilation resistance and reduced collection effect, so it is necessary to replace the new filter frequently

Embodiment Construction

[0049] A filter with a reinforced frame according to an embodiment of the present invention will be described below with reference to the drawings. figure 1 It is a schematic external view of the filter 1 with a reinforcement frame concerning this embodiment. The filter 1 is a range hood filter attached to an exhaust gas suction port of the range hood, and has a flat rectangular parallelepiped shape as a whole. The filter blank is made of glass fiber, and the filter thickness is 5-30 mm, preferably 10-25 mm, most preferably 14-20 mm. The filter 1 is a non-woven fiber filter in which glass fibers are interwoven entirely, and the interweaving density between the fibers in the vertical direction and the left-right direction is different. In this stage, the above-mentioned interweaving density in the left-right direction is larger than that in the up-down direction, and the reinforcing frame 2 is attached to both side edges of the filter body along the up-down direction.

Abstract

The invention provides a filter and exhaust device using the same, wherein the filter has erect retentivity and low cost and does not easily deflect and bend during process without increasing the weight of the unit area and the thickness of the filter. In addition, the invention also provides a manufacture method and device of the filter, capable of increasing the erect retentivity of the filter at low cost. The filter (1) is a non-woven fabrics fiber filter with different interfibrous interweaving densities due to whole and mutually weaving the glass fiber along the vertical direction and the horizontal direction. At the forming step of the basis material of the main body of the filter, the interveaving density along the horizontal direction is larger than the interveaving density along the vertical direction and reinforcement frames (2) are mounted on the two sides of the main body of the filter along the vertical direction.

Description

technical field [0001] The present invention relates to a filter installed on an exhaust device installed near cooking places, kitchens, cooking utensils, etc., to suck and discharge exhaust gases including smoke, oily smoke, cooking odor, combustion gas, steam, oil droplets, etc. generated during cooking. Disclosed are an exhaust device using the same, a method for manufacturing a filter, and a device for manufacturing a filter. Background technique [0002] In a cooking place, a cooking appliance, a kitchen, etc., a range hood or a ventilating fan is installed as an exhaust device, for example. If cooking oil or oil derived from fish or meat evaporates, a large amount of oil and dust will adhere to the surface of the range hood or ventilation fan, and removal work is necessary. Therefore, a range hood filter is installed on the exhaust gas suction port of the range hood to collect oily smoke, dust, etc. Such a range hood filter is, for example, installed horizontally on ...
