[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a filter medium and a filter medium exchange device.

[0002]

[Prior Art]

 As shown in FIGS. 7 and 8, the automatic winding type air filter incorporated into the air conditioner that supplies and exhausts air from above has a filter medium housed in the case A of the main body. The main body case A has an opening on the upstream side of the flow of airflow, and one side wall B of the main body case A is provided with shaft fitting grooves C and D cut from the upstream side end, and the other side wall E has a bearing (not shown). Parts are provided on both sides to support the rewinding shaft F and the winding shaft G. In the drawing, H is a filter medium, I is a guide roller, J is a motor with a speed reducer, K is a sprocket wheel, L is a sprocket wheel attached to a winding shaft G, and M is a chain.

[0003]

[Problems to be solved by the device]

 The conventional device is configured as described above, and drives the motor J with a speed reducer to intermittently rotate the winding shaft G to wind the filter medium H. Then, when the filter medium H becomes unusable, open the door of the air conditioner (not shown), enter the inside, and pull out the rewinding shaft F and the winding shaft G from the shaft fitting grooves C and D to the upstream side. I had to remove it. Therefore, an inspection space for replacing the filter media was required inside the air conditioner body, but it was difficult to make such space large and the work was difficult.

Therefore, in the present invention, the rewinding shaft and the winding shaft can be removed in the axial direction so that the work can be used outside the air conditioning apparatus.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention constitutes a filter medium in which the tip of the filter medium wound on a roll is obliquely cut to form the end portion at an acute angle.

In addition, the case is fixed inside the opening having the opening door of the main body of the air conditioner, the case is provided with front and rear support plates, and both ends thereof are connected by connecting walls, respectively. Mount the movable doors that have bearing holes on the opening side so that they can be opened and closed to the left and right, and fix the suspension panel that has bearing holes and the motor with a reducer on the support plate facing the movable doors, and attach the drive shaft. The drive member panel is fixed, a rewinding shaft with a new filter medium is inserted into the suspension panel and the bearing hole of the movable door, and the filter medium is wound into the drive shaft and the bearing hole of the movable door. This is a device for converting a filter medium into which a winding shaft is fitted.

[0007]

[Action]

 The present invention is configured as described above, and after opening the opening door, open the movable doors on both sides, extract the rewinding shaft and the take-up shaft on which the used filter medium has been wound, and remove the new filter medium. Move the rewinding shaft and the winding shaft, which are wound, into the bearing hole and the drive shaft, close both movable doors, and insert the shaft ends of the rewinding shaft and the winding shaft into the bearing holes. The door is fixed, the opening door is closed, and the movable shaft is intermittently driven to wind up the filter medium. The filter medium is moved by passing it through a guide roller, etc., and the filter medium is attached to the take-up shaft.
