Title: Filter and method for manufacturing the same
Inventor: SHIGEOKA TAKEHIKO
IPC: B01D39/12
Filed: 2001-10-24
Abstract: PROBLEM TO BE SOLVED: To provide a filter provided in the indoor air intake of a room air heater so as to prevent from dust entering, having a high opening ratio and fine meshes and easy to remove dust. SOLUTION: The filter 17 is obtained by smoothing and molding the end surface edges of both or one surface of expanded steel formed by stretching and cutting a steel sheet at normal temperature to form diamond-shaped meshes by plane processing. Therefore, the opening ratio of the filter 17 can be increased and, even if the mesh is made fine, clogging is not occured and the life of the filter can be extended. The dust stucking to the filter can be simply and cleanly removed because the end surface edges of meshes are made smooth and the air passing resistance of the filter 17 after the removal of dust is lowered. The reduction of the amount of air from a blower 14 due to the mounting of the filter can be also prevented and the user's convenience of the filter 17 is sharply enhanced.
