Air exhaust structure for an upright-type vacuum cleaner

Abstract

An air exhaust structure for an upright-type vacuum cleaner capable of a convenient use by providing a filter cover which is not easily opened by a discharging pressure of the air, while the filter cover is easily opened and closed by the user. The air exhaust structure of an upright-type vacuum cleaner has a frame having a duct formed at a side of the cleaner body to communicate with the motor driving chamber, a support member protruded from an inside wall of the duct, a filter, a filter cover having a grill portion disposed at the frame; and a removable means for opening and closing the filter cover. The removable means includes a hook formed at a front end of the filter cover and a locking hole having a locking protrusion disposed at the frame placed at a corresponding position of the hook. The hook includes a fixing portion extended from the filter cover, a flexible pressing portion bent in a direction approximately 180° from the fixing portion, and a pair of protrusions disposed at both sides of the flexible pressing portion and connected with the locking protrusion of the locking hole.
