DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to mounting and replacing an air-conditioning air filter element (hereinafter simply referred to as an air filter) used for controlling airborne dust in a room such as a general building or factory. It concerns the device.

[0002]

2. Description of the Related Art An air filter of this type is generally constructed such that an air filter housed in a housing can be taken out from a replacement port provided in a side wall of the housing and replaced with a new air filter. ing. The periphery of the air filter housed inside the housing is tightly attached to the inner wall surface of the housing via a gasket so that air does not pass through a gap (from the inflow side to the outflow side) other than the air filter.

[0003] In the conventional air filter, the method of closely contacting the periphery of the air filter is roughly classified into two types, one of which is an independent pressing structure, as shown in FIG. The other is an interlocking push structure, as shown in FIG.

[0004] First, an independent pressing structure has an opening frame size equal to the air filter opening area inside the housing and functions as a bone member of the housing. Two guide bars are horizontally disposed so as to support the weight of the air filter, and the bottom surface of the air filter is placed on the two guide bars. From the frame member that defines the left and right openings of this air filter, two studs each, protruding several centimeters from the air filter thickness direction,
It is arranged. In the method of fixing the filter element, two air filter mounting bars are respectively inserted into the upper side and the lower side of the above-mentioned bolts, and the air filters are tightened one by one with four nuts in total.

[0005] However, this method requires work in a narrow space (in the housing). In addition, when the air filter is inserted, the working condition is such that the tip of the stud bolt easily damages the filter medium. Furthermore, 4 times the number of air filters
Double tightening points were generated, and the labor for installation and removal was large, and it was easy to easily forget to tighten the nut.

[0006] Next, an interlocking pusher structure has an opening frame size equal to the air filter opening area inside the housing and functions as a bone member of the housing.
Two guide rails are horizontally disposed so as to support the weight of the filter element, and the filter element carries air filters from the replacement port on the filter rail with the number of openings being equal to the number of openings on the ground side. . In the method of fixing the air filter, two shafts extend in the row direction in which the air filters are arranged in one stage of the air filter, and the shafts are provided with cams four times the number of the air filters. This cam is integrated with the operation lever shaft on the exchange port side, and the lever operation (rotation angle 90 °) allows the air filter to be pressed and moved, and is locked at the top dead center of the cam. . In FIG. 4, the upper camshaft is locked by right rotation, and the lower camshaft is locked by left rotation. The operation procedure is completed by rotating the operating lever on the inlet side of the replacement port by 90 ° one by one after inserting the air filter.

However, in this method, since the amount of pressing movement is fixed, when the air filters are arranged in a plurality of rows (three or more rows), the reaction force of the gasket increases, causing a delay in the rotation angle of the shaft and the occurrence of a counter operation lever. The cam on the side transmits only an insufficient rotation angle, and as a result, the amount of pressing movement decreases, and the air filter tends to be insufficiently adhered.

[0008]
