Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a vacuum cleaner having a dust collection bag inside a dust collection chamber that can be opened and closed with a lid.

Conventionally, in this type of vacuum cleaner, as shown in Fig. 3, the dust collection bag A is set horizontally and the lid B is closed from above. It was pressed from above. In other words, the intake port gasket C was pressed against the mouth core D of the dust collection bag A in a substantially perpendicular direction.

Problems to be Solved by the Invention However, in this configuration, the intake port gasket C
The pressure welding margin is set to 1 to 2 mm, and if the thickness of the intake port gasket C varies or the rotation dimension of the lid B varies, the pressure contact state of the suction port gasket C will vary, causing air leakage. I was getting used to it.

The present invention solves these conventional problems and provides a vacuum cleaner with improved airtightness at the air intake port.

Means for Solving the Problems The present invention solves the above-mentioned conventional problems.
A vacuum cleaner main body having an upwardly opening dust collection chamber at the front, a dust collection bag set in the dust collection chamber and having its opening slanted forward and downward above the dust collection chamber, and a rear dust collection bag. is pivotally supported on the vacuum cleaner body, and is equipped with a lid that opens and closes the upper opening of the dust collection chamber by rotation. A downwardly sloping part is formed, and an inlet gasket that contacts the mouth core is provided on the slanted part, and the inclination of the slanted part of the lid is set relative to the line connecting the tip of the lid and the pivot point. It is set to have a predetermined angle.

Effects According to the present invention, since the direction of the mouth core and the direction of the intake port gasket are inclined while remaining parallel to the direction of rotation of the lid, the direction of pressure contact of the intake port gasket to the mouth core is reduced. The distance traveled is small. Therefore, even if the rotational distance of the lid varies to some extent, the variation in the pressure contact of the intake port gasket to the mouth core is small, and airtight reliability can be ensured.

Embodiments The embodiments will be described below with reference to the accompanying drawings.
In FIGS. 1 and 2, reference numeral 1 denotes a vacuum cleaner main body, and an upper opening of a dust collection chamber 2 formed at the front of the main body is opened and closed by a lid 3. The lid 3 is pivotally supported on the cleaner body 1 via a rear fulcrum 4. Reference numeral 5 denotes a dust collection bag such as a paper bag, which is set in the dust collection chamber 2 by locking the opening core 8 between the insertion frame 6 and the support plate 7.

By the way, the front part of the lid 3 is sloped forward and downward, and the intake port 9 to which the intake port gasket 10 is attached is formed in this part, and also becomes parallel to the intake port gasket 10 when the lid 3 is closed. Mouth core 8
The set state is also set at an angle.

Now, when the lid 3 is rotated in the closing direction based on the fulcrum 4, if the inclination of the mouth core 8 and the intake port gasket 10 with respect to the rotation direction is set as α, then the downward movement distance a of the lid 3 is Therefore, the moving distance b of the intake port gasket 10 in the pressing direction becomes b=a sin α, which is small.

This means that even if the rotation distance of the lid 3 varies due to rattling of the fulcrum 4, etc., the variation in the pressure contact direction of the intake port gasket 10 is smaller than the variation in the downward direction. As a result, variations in the rotation distance of the lid 3 are absorbed.

This ensures air tightness and improves quality.

Effects of the Invention As described above, the present invention makes the lid for opening and closing the dust collection chamber rotatable via a fulcrum, and provides the suction port gasket obliquely with respect to the direction of rotation immediately before closing. The position of the mouth core of the dust collection bag when the lid is closed is set so that it is in parallel contact with the intake port gasket, so the intake port gasket and the mouth core are tilted at a certain angle with respect to the direction of rotation of the lid. Therefore, the moving distance of the intake port gasket in the pressure direction is smaller than the rotation distance of the lid (sin α
times). Therefore, even if the rotation distance of the lid varies for some reason, the variation in the pressure welding distance of the intake port gasket is small, and quality improvements such as ensuring air tightness are achieved.
