Abstract

PURPOSE:To facilitate the installation of an elastic body and accelerate the quietness of the passing sound by extending a dust collecting chamber up to the upper part from an outer partitioning wall inside a body outer partitioning wall and surrounding the dust collecting chamber by the dust collecting chamber wall which has a nearly square-shape and is opened in the upper part, and installing a packing made of elastic material at the upper edge of the dust collecting chamber wall and allowing a cover to have a wall contacting with the elastic body packing. CONSTITUTION:As for a dust collecting chamber 28, a nearly square-shaped wall elastic body packing 32 is installed on a rib 33 which is opened in the upper part of a nearly square- shaped wall 33 inside the body outer partitioning wall 24 of a body A24, and fixed from above by the rib 25A of a cleaner body B25 and the rib of a cleaner body A24A. A cover 26 which covers the dust collecting chamber 28 and is freely opened and closed is fitted, and elastically contacts with a nearly square-shaped elastic body lip 32, and the airtightness of the dust collecting chamber 28 is secured. As for the dust collecting chamber 28, the elastic body packing 32 can easily be installed by the nearly square-shaped wall 33 extended to the upper part of the body outer partitioning wall 24 inside the body outer partitioning wall 24, and airtightness can be secured. Because of this double wall, the quietness of the passing sound can be accelerated.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vacuum cleaner in which a substantially rectangular dust collecting chamber wall opening upward is added to the inside of the outer wall of the main body of the vacuum cleaner.

BACKGROUND OF THE INVENTION In general, the dust collection chamber wall of a vacuum cleaner consists of a vacuum cleaner main body 1, a vacuum cleaner main body left IA, a vacuum cleaner main body cloth IB, and a dust collection chamber lid IC, as shown in FIGS. 4 and 5. It has a built-in electric blower 2. A substantially rectangular elastic gasket 6 is installed in the dust collection chamber 3 of the left IA of the vacuum cleaner body at the elastic body mounting groove 4 and the elastic body mounting wall 5.
, and form an exhaust lower on the vacuum cleaner body cloth IB that fits the dust collection chamber IC into the vacuum cleaner body left IA, and also
has a handle 8 at the top and a telescopic extension tube 9 at the bottom.
are connected and fixed by a tightening ring 10, and a floor nozzle 11 is connected to the tip of the extension pipe 9.

In addition, as shown in FIGS. 6 and 7, the vacuum cleaner body 1 includes a lower vacuum cleaner body 13, an upper vacuum cleaner body 14, and a dust collection chamber lid 1.
5, it has a built-in electric blower 16, and the lower body 2
The dust collection chamber 17 has a main body bumper/elastic gasket 18 that is connected to a wall 13A outside the vacuum cleaner main body at the bottom 13 of the main body and a mounting groove 13.
The main body bumper/elastic body lip is inserted between B, and the dust collection chamber cover 15 is attached to the lower part 13 of the vacuum cleaner main body.

a vacuum cleaner main body 12; a hose 19 connected to the main body 12;
A hose connecting pipe 20 is connected to the hose 19 at one end, and a stopper 21 is connected to the hose connecting pipe 20 at one end and a floor nozzle 22 at the other end.

Problems to be Solved by the Invention In the conventional vacuum cleaner as described above, the outer wall of the main body is the same as the dust collection chamber, so the elastic gasket is attached to the outer wall of the main body in the groove below the upper part of the wall. Since it is press-fitted into the ribs, it is not easy to install, and since it only has walls outside the main body, the passing sound is very noisy, resulting in insufficient noise reduction.

The present invention solves these conventional problems by extending the dust collection chamber from a substantially rectangular wall to above the outer wall.
The approximately rectangular elastic body is easy to install, and the double walls help reduce passing noise.

Means for Solving the Problems In order to achieve the above object, the means of the present invention includes a main body having a dust collection chamber and a ventilation chamber, and a cover that can be opened and closed to cover the dust collection chamber and above, The chamber extends inside the outer wall of the main body and above the outer wall, and is surrounded by a substantially rectangular dust collection chamber wall that opens upward, and a gasket made of an elastic material is attached to the upper end of the dust collection chamber wall. The lid has a wall that comes into contact with the elastic packing.

According to the means of the present invention, by forming a substantially rectangular wall inside the outer wall of the main body, the substantially rectangular elastic packing can be properly installed, and the double walls can accurately reduce passing sound.

Example Examples thereof will be described below with reference to the accompanying drawings.

In FIGS. 1 to 3, the vacuum cleaner main body 23 is formed by a vacuum cleaner main body A24 and a vacuum cleaner main body B25, and has a dust collection chamber 2 at the front.
Air blower installation chambers are respectively formed at the rear of a cover 26 which can be opened and closed and which covers the upper part of the air blower. Further, a floor nozzle 30 is inserted into the front side of the cleaner main body 23, and a floor nozzle 30 is disposed on the other end side via the floor nozzle 31 between the cleaner main body A 24 and the vacuum cleaner main body B 25. The dust collection chamber 28 has a rib 33 that opens above a substantially rectangular wall 33 on the inside of the outer wall 24 of the main body A24.
A substantially rectangular wall elastic gasket 32 is attached to the vacuum cleaner main body B25 and fixed from above by the rib 25A of the vacuum cleaner main body B25 and the rib of the vacuum cleaner main body A24A. A lid 26 that can be opened and closed to cover the dust collection chamber 28 is inserted and comes into elastic contact with a substantially rectangular elastic lip 32, so that the airtightness of the dust collection chamber 28 is maintained.

In the vacuum cleaner having the above structure, the dust collection chamber 28 has a substantially rectangular wall 33 extending inside the outer wall 24 of the main body and above the outer wall 24 of the main body, so that the elastic gasket 32 can be attached to the main body. and maintain airtightness.

Additionally, the double walls help reduce passing noise.

Effects of the Invention As described above, according to the present invention, a substantially rectangular inner wall is provided inside the outer wall of the main body and extends above the outer wall. Walls can help reduce passing noise.
