Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing filter for an air conditioner.

[0002]

2. Description of the Related Art Generally, an air conditioner is provided with a deodorizing filter for removing a malodorous component in an airflow flowing through the air conditioner in a predetermined direction with respect to the airflow. This deodorizing filter is provided with a mold and a filter medium as disclosed in, for example, Japanese Utility Model Laid-Open No. 4-106624. The mold has a configuration in which one surface orthogonal to the direction of the ventilation flow and another surface opposite thereto have ventilation openings, and a ventilation path is defined between these openings. The filter medium is arranged in the air passage so as to cover the opening while being supported by the mold, and is composed of a filter paper for removing the malodorous component. In the air conditioner provided with the above deodorizing filter, the deodorizing filter is detachably provided because it needs to be replaced with a new deodorizing filter when the adsorbing power of the malodorous component by the deodorizing filter decreases.

[0003]

However, this conventional device has a problem that it is difficult to attach and detach the deodorizing filter to and from the air conditioner. Because the filter medium is made of paper, it bends and hangs down from the opening of the mold. Therefore, when the deodorizing filter is attached to or detached from the air conditioner, the hanging portion is caught by the filter mounting portion of the air conditioner and becomes an obstacle.

In order to solve such a problem, it is conceivable to reinforce the filter medium by sandwiching both sides of the filter medium with a net or the like. However, such a net or the like becomes a resistance to an air flow and causes a pressure loss. It is expected to increase. The present invention has been made in view of the above points, and an object of the present invention is to provide a deodorizing filter for an air conditioner that is easy to attach and detach and has a small pressure loss.

[0005]

According to the first aspect of the present invention,
A deodorizing filter that is removably provided in an air conditioner and is arranged in a predetermined direction with respect to an airflow, and has one surface that is orthogonal to the airflow direction and another surface that faces the airflow. A mold having openings for use and partitioning a ventilation path between these openings, and a ventilation flow disposed in the ventilation path so as to cover the opening while being supported by the molding frame and flowing into the ventilation path. In a deodorizing filter for an air conditioner provided with a filter medium made of a filter paper for removing a malodorous component, a long flat plate-shaped reinforcing material whose longitudinal direction is orthogonal to the ventilation direction is fixed to the filter medium. The reinforcing material is provided in such a manner that the area of the surface facing the airflow direction is smaller than the area of the surface extending in the airflow direction, which is a deodorizing filter for an air conditioner.

According to a second aspect of the present invention, in the deodorizing filter for an air conditioner according to the first aspect, both longitudinal ends of the reinforcing member are supported by the mold. Is. According to a third aspect of the present invention, in the deodorizing filter for an air conditioner according to the first or second aspect, a reinforcing flange portion is provided on at least one of upstream and downstream ends of the reinforcing material in the airflow direction. Are formed.

The invention according to claim 4 is the invention according to claims 1 to 3.
In the deodorizing filter for an air conditioner according to any one of the above, the filter medium is composed of a laminated body in which a corrugated plate and a flat liner plate are alternately laminated, and the reinforcing material is laminated in the laminated body. It is characterized by being present.

[0008]

According to the first aspect of the invention, the reinforcing material is fixed to the filter medium made of filter paper. As a result of the bending of the filter medium being prevented by this reinforcing material, it is possible to prevent the filter medium from hanging down from the opening of the mold. The reinforcing member is formed in a long flat plate shape, and is provided such that the area of the surface facing the airflow direction is smaller than the area of the surface extending in the airflow direction. That is, the reinforcing material is attached to the filter material so that the projected area viewed from the upstream side of the ventilation flow becomes the smallest. Therefore, the resistance given to the ventilation flow by the reinforcing material can be suppressed to the minimum, and the pressure loss can be suppressed to the minimum.

According to the second aspect of the invention,
Since both ends in the longitudinal direction are supported by the mold, the reinforcing material can be prevented from being displaced with respect to the mold, and as a result, the filter material can be reliably prevented from hanging down from the opening. According to the invention of claim 3, the rigidity of the reinforcing material itself is increased by the reinforcing flange portion, so that it is possible to reliably prevent the filter material from hanging down from the opening.

According to the fourth aspect of the present invention, the reinforcing material is laminated on the laminated body in which the corrugated plates and the liner plates are alternately laminated. Therefore, in the case of manufacturing the same, it is only necessary to stack the reinforcing material in the same manner as the corrugated board and the liner board when the laminated body is laminated. Therefore, the reinforcing material of the present invention can be attached to the laminated body in the process of manufacturing the laminated body, which facilitates the production of the deodorizing filter. On the other hand, when the filter medium is sandwiched by the conventional net, the net is attached to the laminated body in another step after the laminated body is manufactured, which requires time and effort for production.
