Problems solved by technology

That is, the simplified and thinned filter is generally weak in strength, and in long-term use, it is easy to be deformed due to the increase of pressure loss along with the clogging of the filter
On the other hand, in the structure disclosed in JP-A-2000-280737, in which the strength of the filter is increased, the performance of attaching and detaching the filter in a small space becomes poor, and the method for increasing the strength of the filter Reinforcement will increase the cost of manufacturing the filter

Embodiment Construction

[0019] Hereinafter, preferred embodiments of the filter according to the present invention will be described with reference to the accompanying drawings.

[0020] 1 and 2 show a filter according to an embodiment of the present invention, and show a filter suitable for situations requiring attachment and detachment in a small space, in particular, suitable for use in a vehicle air conditioning system. 1 and 2 show the state before attachment and the state at the time of attachment, respectively.

[0021] In Figures 1 and 2, the filter 1 includes: a sheet-shaped filter material 2 that can be folded in a pleated form; two filter frame parts 3 are respectively arranged on both sides of the filter material 1 in the transverse The material 2 extends and folds freely in the longitudinal direction; and a plurality of support members 4 are arranged in the longitudinal direction of the filter material 2 and respectively extend between two filter frame members 3 in the transverse directi...

Abstract

Disclosed is a filter (1) comprising a sheet-like filter material (2) capable of being folded in a pleat form, two filter frame members (3) each provided on each side of the filter material (2) and each free to be expended and folded in the longitudinal direction of filter material (2), and a plurality of support members (4) appropriately arranged in the longitudinal direction of the filter material (2) and each of which extends between two filter frame members (3) in the transverse direction of the filter material (2). By this invention, provided is a filter excellent in attachment and detachment property in a small space, and having a sufficient strength at a simple structure, and which can be manufactured at a reduced cost.

Description

technical field [0001] The present invention relates to a filter that is used in a pleated form, and in particular, to a filter that is excellent in attaching / detaching properties and is suitable for use in a vehicle air conditioning system or the like. Background technique [0002] For example, with regard to filters used in vehicle air-conditioning systems for cleaning the air inside vehicles, with the recent demand for making air-conditioning systems smaller and lighter, there has been an increased need to simplify the structure, make the filter thinner, and reduce the cost of manufacturing the filter. Because vehicle air conditioning systems are typically located within the vehicle's dashboard, it is often difficult to ensure sufficient work space to attach and remove the filter. Therefore, there is known a filter having a structure in which a part of the filter is folded for its attachment and detachment (for example, JP-A-2005-7361). In addition, there is also known a...
