SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a vacuum cleaner that can prevent the lid of the dust collection chamber from being accidentally opened during transportation.

[Means to solve the problem]

In the present invention, a handle provided on a vacuum cleaner body having a dust collection chamber with an opening on the top surface at the front is formed from a grip part and a main body engaging part, and the main body engaging part is located near the rear of the dust collecting chamber. The handle is attached to a handle mounting portion provided on the vacuum cleaner body so as to be movable between a gripping position and a non-gripping position, and the dust collection chamber lid opens and closes the top opening of the dust collection chamber. Rotatably attach the edge to the vacuum cleaner body,
The dust collection chamber lid is constantly biased in the opening direction by a spring, and a closed state of the dust collection chamber lid is controlled at the front end of the vacuum cleaner body by an operating body that can be freely engaged and detached from the front edge of the lid. It is applied to a vacuum cleaner that is held by engaging with a lid clamp provided at the part.

And, in order to achieve the above purpose, this invention
A rotation prevention part is provided at the rear edge of the dust collection chamber lid, an engaging part is provided at the main body engaging part of the handle, and a wall part located near the rear of the dust collection chamber is formed on the vacuum cleaner body. A crankshaft is rotatably attached to the crankshaft by penetrating it in the front-rear direction, and a crankshaft protrudes from the outer periphery of the front part of the crankshaft and comes into contact with or comes close to the rotation prevention part when the handle is moved to the gripping position. Lid stoppers are provided at the rear of the crankshaft and protrude from the outer periphery of the crankshaft to hold the handle in place. When the handle is placed in both the grasping position and the non-gripping position, the lid stopper is brought into contact with or close to the rotation inhibiting portion and a position in which it is separated from it by moving the handle to both positions. A connecting rod is provided to move the lid stopper and the handle, and the distal end of the connecting rod is engaged with the engaging portion to connect the lid stopper and the handle via the connecting rod and the crankshaft.

[Effect]

According to the present invention, when the handle is moved to the gripping position and the main body of the vacuum cleaner is carried by gripping the handle, the tip portion is engaged with the engaging portion as the handle is moved to the gripping position. Since the crankshaft is rotated in one direction via the connecting rod, the lid stopper provided at the front of the crankshaft is also rotated in the same direction. Due to the displacement of the lid stopper due to this movement, it is caused by the rotation prevention part of the dust collection chamber lid in the closed state.
placed in abutting or proximate positions. Therefore, even if the dust collection chamber cover naturally rotates in the opening direction due to the biasing force of the spring when the clamp is released by mistake, the rotation movement is prevented from reaching the lid stopper of the rotation suppressing part. This can be prevented by contact. In addition, in the non-carrying state where the handle is moved to the non-grip position, as the handle moves to the non-grip position, the connection rod whose tip end is engaged with the engaging part is inserted. Since the crankshaft is rotated in the opposite direction, the lid stopper is also rotated at the same time as the crankshaft.
This lid stopper is arranged at a position away from the rotation suppressing portion. In this state, the lid stopper is positioned so that it does not interfere with the rotation of the dust collection chamber lid.
The dust collection chamber lid can be opened and closed at will.

There is no. That is, rotation of the dust collection chamber lid 30 in the opening direction about the shaft portion 31a is prevented by the contact between the mounting arm 31 and the lid stopper 48. For this reason,
The user can carry the vacuum cleaner main body 21 with peace of mind.

Further, when the handle 30 is pushed down, the stored state is automatically held by the knob 45, and along with this storage, the lid stopper 48 is separated from the mounting arm 31 via the interlocking mechanism 49. It is retracted to a position where rotation of the dust collection chamber cover 30 is not hindered. This condition is shown in FIGS. 2, 5 and 6. Therefore, when the dust collection chamber lid 30 is released from the lid clamp 34 when the dust collection filters 28 and 29 are attached and removed, the dust collection chamber lid 30 is automatically opened by the force of the torsion spring 32. .
