DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vacuum cleaner in which a dust collecting bag is detachably mounted in a dust collecting chamber, and more particularly to an erroneous mounting preventing mechanism for preventing a lid from being mounted when the dust collecting bag is not mounted. Regarding improvement.

[0002]

2. Description of the Related Art Conventionally, as a mechanism for preventing erroneous mounting of this kind of vacuum cleaner, for example, Japanese Utility Model Laid-Open No. 62-146456 (A47L 9/1)
4) is known. In this vacuum cleaner, an erroneous mounting prevention member which is retracted by mounting a dust collecting bag is formed in a dust collecting chamber formed in a main body, and the dust collecting chamber is closed with a lid when the dust collecting bag is not mounted. In this case, the lid comes into contact with the erroneous mounting prevention member to prevent the lid from being mounted. The lid is mounted by engaging engagement portions formed on both sides facing each other with the locking portion of the main body, and the erroneous mounting prevention member is formed near one locking portion for locking the lid. One of the engaging portions of the lid is engaged with the locking portion of the main body, and the lid is rotated around the engaging portion as a fulcrum to lock the lid to the main body. In this configuration, when the lid is to be mounted without the dust bag attached, the lid tends to retreat in the direction of the side facing the side where the erroneous mounting prevention member is formed. Since the engaging portion is formed in the cover, the cover does not retreat, so that erroneous mounting of the cover can be reliably prevented.

However, in the above conventional structure,
In upright type vacuum cleaners, a suction port for mounting a floor suction tool is formed on the side of the side where the dust collecting bag is mounted, so that when cleaning a gap in furniture or the like, it is used for the floor. Instead of the suction device, a clearance suction device must be installed, and the entire vacuum cleaner must be operated and cleaned. This makes it difficult to handle and makes the cleaning operation difficult.

Accordingly, one end of a bellows hose is detachably connected to a floor suction tool provided at the lower portion of the main body, and the other end of the bellows hose is connected to the side of the dust collection chamber, thereby providing a floor suction. When suctioning dust from the fitting into the dust collection bag of the dust collection chamber through the bellows hose and cleaning the gaps in furniture, etc., connect the gap suction tool to one end of the bellows hose removed from the floor suction tool. It is conceivable to configure so that

In this configuration, the suction port to which the bellows hose is connected and the mounting portion to which the dust collecting bag is mounted are provided on the side surfaces adjacent to the both side surfaces on which the locking portions to be engaged with the engaging portions of the lid are formed. Therefore, if the lid is to be mounted without the dust collection bag, the lid is retracted to the side opposite to the side where the erroneous mounting prevention member is formed, and the lid is closed. There was a case where it was attached by mistake.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks, and has a structure in which a mounting portion of a dust collecting bag is not formed near an engaging portion with which an engaging portion of a lid engages. An object of the present invention is to provide a vacuum cleaner capable of reliably preventing erroneous mounting of a lid.

[0007]

According to the present invention, there is provided a main body having a blower chamber for accommodating an electric blower and a dust collection chamber for detachably storing a dust bag, and an opening of the dust collection chamber to be opened and closed. A lid, an engaging means provided on one side of the dust collecting chamber, for engaging and disengaging the lid with the main body, and swinging to the other side adjacent to one side of the dust collecting chamber; And a locking member for locking the dust collection bag in a detachable manner, wherein the locking member has projections formed on both sides in the swing direction with respect to the swing center of the locking member, The lid is characterized in that a plurality of blocking portions are formed on the lid to abut against the protruding portions of the locking member when the dust bag is not mounted to prevent the lid from being mounted on the main body.

[0008]

[0009]

[0010]

When the lid is accidentally mounted without the dust bag, the blocking portion of the lid comes into contact with the plurality of protrusions of the engaging member, and the engaging portion of the lid locks the main body. Prevent engagement with the part. At this time, since the lid is positioned on both side portions adjacent to the side portion on which the locking member of the main body is disposed, the lid moves in the lateral direction, and the blocking portion of the lid is moved to the projecting portion of the engaging member. There is no erroneous attachment such that the lid is attached to the main body without contact with the main body. Further, since the plurality of protrusions of the engagement member are formed on both sides in the swinging direction with respect to the center of rotation, when the lid is to be mounted without the dust collection bag, the plurality of protrusions of the engagement member are provided. Each of the protrusions abuts the blocking portion of the lid, so that there is no erroneous mounting such that the engaging member swings and the lid is mounted.
