JP2006090106A - Ventilation method for improving micro-filtering action by fixing opening part such as person staying space or ventilation intending raw material in window, door and other - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide an improved ventilation means for easily attaching-detaching a filter unit, by fixing micro-filtering ventilation for adopting a long-term reusable filter in a person staying space such as a detached house, a multiple dwelling house, the other building system or a vehicle. <P>SOLUTION: In this improved ventilation means, a detachable micro-porous filter is fixed in an opening part such as a window, a door and a ventilating opening. Thus, the means can be reused by periodically cleaning, and can be easily attached detachably from a window frame, the door and the other opening frame. Clean air can be directly taken in from the window, the door and the ventilating opening as a further superior practical product, and as a result, the means is useful for preventing an allergy by pollen and dust intruding from ventilation and outside air for preventing a sick building syndrome. An adjusting range of a ventilation quantity can also be maximized by increasing the ventilation surface area to the size of an opening, by applying and installing mini-pleats to and in the filter. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

Detailed Description of the Invention

  The present invention relates to a ventilation means, and by installing a filtering material in an opening portion such as a window, a door, a ventilation opening, a single wall opening frame, or a space where a person is located, whether or not an electric blower is used. Regardless, it relates to providing clean ventilation for indoor spaces.

  In order to ventilate the indoor space, there are various methods such as using an electric blower or simply opening a window or a door.

There is a large pore matte filter, a mechanical system that uses a fiberglass type that primarily serves to trap airborne particles and requires disposal or replacement. (See, for example, JP-A No. 2001-311372, No. 59-27138, Cecil Gordon Vokes, British 616,497)

Problems to be solved by the invention

  The method using an electric blower requires the use of electric power, whereas the method of simply opening a window or door does not require any power, but as a method to prevent the entry of mud, dust and pollen. Is insufficient. Large pore mat filters need to be replaced and discarded.

  As energy costs have risen dramatically since the 1970s, buildings have become more elaborate in Japan. This more elaborate construction led to the accumulation of harmful gases from indoor space products and building materials, causing problems known as chic building syndromes.

Means for solving the problem

With regard to the revision, the present invention is a long-term usable type that provides clean ventilation for indoor spaces with or without the use of an electric blower. Or a door or a single wall opening frame, or installed in a space where a person is located.

  The material of the filtration medium can be a plastic material such as polyester, polypropylene, carbon-arranged fibers, woven metal, other metallic materials, nanostructured materials, etc., or a single material or multiple Materials that are suitable for the purpose are used.

  The present invention is an improvement of a building system and ventilation system that replaces a mechanical system that uses a fiberglass type that functions as a large pore mat filter, mainly trapping particles in the air and requires disposal or replacement. is there. The present invention is a micron filtration material that consists of at least one layer of long-term use that normally repels rather than traps dust particles, and this material is a window frame, for periodic cleaning and reuse. It is intended to be easily detachable from doors and other opening frames.

  Ventilation on many windows and doors, including screens, does not help prevent particle entry in most small air. The present invention ventilates a micro screen with a pore size of 1 to 120 microns, or a hole size that does not allow most air mud, dust, or pollen with allergens such as cedar pollen to enter. Means.

  The invention works without the use of electric blast or other electrical devices, but combinations are also contemplated. The material can be flat or pleated to increase the filtration area. The invention can be used to provide continuous ventilation or can be used only during periods of high need such as the hay fever season. It can be used alone or in conjunction with other systems such as mechanical systems, opening windows and doors.

  The window unit 1 has a frame 2 on which a filter material 3 for providing ventilation is stretched, which is a part of the structure. A piece of the frame is covered with a door 4 for the purpose of adjusting the amount of ventilation and to open and close the vents and vent closure / louvers. It can be considered as an independent one shown in the figure, or simultaneous use with a blower not shown in the figure. It is configured vertically on the side of the window or horizontally on the top of the window.

  The removable micro screen 2 can be easily removed and maintained by spring clips 5, latches, snap-on clasps, or simply a fitting method, etc., and various methods can be used for windows (doors, open frames) ).

The invention's effect

  The main object of the present invention is that it can be periodically cleaned and reused and can be easily attached and detached from window frames, doors and other open frames.

  As a better practical product, the present invention can take clean air directly from windows, doors, and ventilation openings. Useful for ventilating to prevent sick building syndrome and preventing allergies caused by pollen and dust entering from outside air.

  By attaching and attaching mini-pleats to the filter, the ventilation surface area can be increased with respect to the size of the opening, and the adjustment range of the ventilation volume can be maximized.

  It is a front view of an example of the possible shape and configuration of a standard type sliding window invention.   It is an expansion detailed cross-sectional view of the section A part of a window frame.   FIG. 3 is a cross-sectional view of the substitute filter unit of FIG. 2 in which a filter material is pleated.
