Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a multi-layer filter, and more particularly to a multi-layer filter which has a certain strength and can be easily attached and used when dust filtration is required.

[0002]

[Prior art]

 Conventionally, filtration equipment equipped with a filter is widely used in places where air needs to be filtered, such as various types of air conditioning equipment and factories at home. Many of the filters installed in the filtration equipment are knitted with thin threads. When used, the mesh is made dense by stacking multiple filters, and the fine mesh is used to adsorb dust to filter. .

As shown in FIG. 4, the conventional multilayer filter (30) is formed by knitting a plurality of thin yarns and combining them, so that the overall strength is low. For example, as shown in FIG. 3, when a film is attached to an air conditioner (20) (for example, an air conditioner) in which a slit (22) for inserting a filter is installed in a ventilation hole (21), the strength of the filter is reduced. In general, the filter (30) is attached to the frame (31) in advance and then inserted into the slit (22) for each frame (31) before use.

[0004]

[Problems to be solved by the invention]

 However, as described above, since the filter (30) is soft and has low strength, it must be attached to the frame (31) before being inserted. It is very inconvenient to manufacture the filter (30) by using high-frequency bonding, tacking, or an adhesive, since the filter (30) must be strongly adhered in order to have tension. Further, in the conventional filter, since the mesh of each layer is constant, there is a problem that it takes time and effort to clean the dust stuck to the mesh.

[0005]

[Purpose of the invention]

 The present invention has been made to solve the above-described problem, and combines the upper layer with a medium mesh fineness, the wavy middle layer with a fine mesh, and the lower layer with a coarse mesh to reduce the strength of the filter. An object of the present invention is to provide a multilayer filter that can solve the problems of the conventional filter by improving the filter.

[0006]

[Means for Solving the Problems]

 According to the present invention, an upper layer (11) having a medium mesh fineness, an intermediate layer (12) having a fine mesh and a lower layer (13) having a coarse mesh are laminated, and the upper layer (11) and the intermediate layer (11) are laminated. 12) is a woven fabric in which yarns are knitted vertically and horizontally, and the lower layer (13) is made of a plurality of parallel thick yarns, and the thick yarns are combined with the wavy edges of the middle layer (12). Provide a multilayer filter.

[Embodiment of the invention]

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a multilayer filter according to the present invention, FIG. 2 is an exploded perspective view showing a multilayer filter according to the present invention, and FIG. 3 is an embodiment of the multilayer filter according to the present invention. FIG. 4 is a view showing an example, and FIG. 4 is a perspective view showing a conventional filter.

As shown in FIGS. 1 and 2, the multilayer filter (10) according to the present invention includes an upper layer (11) having a medium mesh fineness, and an intermediate layer (12) formed in a wavy shape and having a fine mesh. , And a lower layer (13) having a coarse mesh.

The upper layer (11) is a net formed by knitting thin yarns alternately vertically and horizontally to have a medium mesh of the mesh of the middle layer (12) and the mesh of the lower layer (13), The middle layer (12) is formed by forming a mesh previously knitted to have a fine mesh into a wavy shape having a certain strength by a chemical under the control of temperature and speed. Are sewn together at the time of knitting.

Also, the lower layer (13) couples several sets of thick yarns (131) to the other side of the middle layer (12), that is, the thick yarns (131) of each set of the lower layer (13) are parallel. Is knitted around the protruding edge of the middle layer (12) to form a net having coarse stitches.

Further, as shown in FIG. 3, when the filter (10) according to the present invention is attached to the air conditioning equipment (20), the ventilation holes (21) and (23) of the air conditioning equipment (20) are not provided. The filter is mounted in the slit (22) for inserting the filter formed between the filters. The filter (10) according to the present invention has a certain strength, and is inserted and mounted in the slit (22) as it is. It can be very convenient. Also, when the filter (10) of the present invention is used by being attached to a frame, the filter (10) of the present invention has a certain strength, so that it can be finished to a flat overall appearance and is fixed to the frame by bonding or other means. Even at times, there is no need to attach after sticking, so work is very easy.

When performing filtration using the filter (10) of the present invention, dust in the air is generated when the mesh passes through the middle upper layer (11) and passes through the fine wavy middle layer (12). , Filtered through a fine mesh. After a certain period of use, the dust adsorbed on the mesh of the middle layer (12) may absorb the moisture in the air and combine to form large particles, but the lower layer (13) in the filter (10) of the present invention may be used. Since it has a coarse stitch, washing with water makes it easier to wash out large granular masses, which not only makes cleaning easier, but also reduces wind pressure and reduces noise.

[0014]

[Effect of the invention]

 As is clear from the above description, the multilayer filter according to the present invention is formed by laminating an upper layer having a medium mesh fineness, a wavy middle layer having a fine mesh, and a lower layer having a coarse mesh. The middle layer is a woven fabric in which yarns are knitted vertically and horizontally, and the lower layer is composed of a plurality of parallel thick yarns.These thick yarns are combined with the wavy edges of the middle layer, so they have a certain level of strength. It is not necessary to use it after pasting it on the floor, and it is easy to clean and has the effect of increasing ventilation and reducing noise.
