  However, in the invention disclosed in Patent Document 1, although the assemblability is improved, since the shape of the functional material itself is a special shape such as a stick shape, a sufficient air passage cross-sectional area is ensured. However, the problem that it is difficult to fully exhibit the effect of the functional material remains. In addition, if a large number of functional materials are arranged to ensure a sufficient cross-sectional area of the air passage, an undesired problem that pressure loss increases and a decrease in air conditioning performance may occur.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle air conditioner filter capable of realizing function selectivity capable of meeting various demands of a user while maintaining air conditioning performance at a high level similar to that of the prior art. .

  In order to solve the above-mentioned problems, a vehicle air conditioner filter according to the present invention includes a laminated filter member composed of a plurality of laminated filter materials having different characteristics or functions, and a frame body that holds the laminated filter member. A filter for a vehicle air conditioner, wherein the plurality of filter materials are laminated in a substantially non-adhered state so that a stacking order can be arbitrarily set and adjacent filter materials can be separated from each other. It consists of what is characterized by.

With such a configuration, the pressure loss of the multilayer filter material can be further reduced, and the air conditioning performance is maintained at a high level similar to that of the prior art.

  The filter material is not particularly limited, but is preferably formed in a pleated form that can be easily stacked and has a large surface area. The pleated structure increases the effective filtration area and improves the filter function. Further, by folding the filter material along the pleats, it is possible to save the space of the filter material when not attached, and it is possible to reduce storage cost and transportation cost.

  The function imparted to the filter material according to the present invention is not particularly limited. For example, in addition to the dust collecting function, the deodorizing function, the antibacterial function, the antiallergen function, the antioxidant function, the aroma function, the humidity adjusting function, and the generation of negative ions Functions and the like.

  The filter for a vehicle air conditioner according to the present invention is easy to replace the filter material as described above, and can arbitrarily set the stacking order of the filter material. In consideration of the above, it can be arranged at any optimum position with respect to the conditioned air delivery path. Therefore, even in the case of a filter material having an active ingredient release function that requires periodic replacement work, the installation position can be set to any optimum position in consideration of replacement work efficiency and the like. it can. Examples of such a filter material having an active ingredient release function include a filter material having an aroma function and a negative ion generation function. In this case, examples of the active ingredient include an aroma generator and a negative ion generator. It is done.

  As described above, according to the vehicle air conditioner filter according to the present invention, it is possible to improve the assemblability and maintainability while minimizing the pressure loss by laminating the filter materials in a non-adhered state. . Further, since desired different characteristics and functions can be easily imparted to the respective filter materials to be laminated, desirable performance according to various demands of users can be imparted to the entire filter.
