However, in the above-mentioned conventional configuration, an intake grille 8 is provided as a separate component for holding the intake filter 10, and the air inlet of the electric blower 5 has a large number of components. The configuration around it was complicated.

Further, since the number of parts is large, the assemblability is deteriorated, and it is necessary to make the configuration inexpensive.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide an easy-to-use vacuum cleaner which holds an intake filter with a simple structure without increasing the number of parts for holding the intake filter. The purpose is.

[0008]

In order to achieve the above object, according to the present invention, a partition for partitioning a dust collecting chamber and an electric blower chamber is provided.
A substantially L-shaped rib is formed integrally with a main body case composed of a plurality of parts and protrudes toward the dust collection chamber in the vicinity of a joint portion of the plurality of main body cases on the partition wall, and provided on a dustproof filter. The substantially L-shaped rib is inserted into the cut portion, and the dustproof filter is locked.
The filter can be easily held without using a separate part.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION
A partition partitioning the dust collecting chamber and the electric blower chamber is formed integrally with the main body case composed of a plurality of parts, and substantially L protruding toward the dust collecting chamber near the joint of the plurality of main body cases with the partition. A substantially rib-shaped rib is inserted into a cutout provided in the dust-proof filter, and the dust-proof filter is locked, so that the filter can be easily formed without using a separate part. Can be held.

According to a second aspect of the present invention, in the first aspect of the present invention, the tip of the substantially L-shaped rib is protruded from the mating portion of the main body case. This makes it easy to form a substantially L-shaped rib.

According to a third aspect of the present invention, in accordance with the first or second aspect of the present invention, a guide rib for covering the outer periphery of the dust-proof filter is provided on the partition wall. And the filter can be prevented from moving with respect to the air flow to support the filter.

According to a fourth aspect of the present invention, in the first aspect of the present invention, a support rib for supporting a dust-proof filter is provided on the partition wall. The filter can be reliably held without providing a filter.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a side sectional view of an electric vacuum cleaner according to an embodiment of the present invention, and FIG. 2 is a partial perspective view of the electric vacuum cleaner. 3 is a sectional view taken along line AA of FIG. 1, and FIG. 4 is a sectional view taken along line B of FIG.
It is -B sectional drawing.

The cleaner body 15 has a built-in electric blower 16 for generating a suction force, and a front support 17 made of an elastic material is provided in front of the electric blower 16.
A rear support 18 made of an elastic material is provided behind the electric blower 16, and a front support 17 and
The rear support 18 is provided on a wall 19 provided on the cleaner body 15.
Has been pinched.

The main body case accommodating the electric blower 16 has a two-part structure of a main body case right 20 and a main body case left 21, and is formed in front of the electric blower 16 by a main body case right 20 and a main body case left 21. A partition 23 is located, and the partition 23 is provided with an air passage hole 22. The partition wall 23 defines a dust collection chamber 24 and an electric blower chamber 35, and a connection port 25 is provided in front of the dust collection chamber 24.

The dust collecting chamber 24 collects dust, and has a substantially cylindrical dust box 27 provided with an air inlet 26. The air sucked by the operation of the electric blower 16 is connected to the dust collecting chamber 24. The dust is collected in the dust box 27 from the air inlet 26 of the port 25 to the air inlet 26, and further passes through the partition 23 having the air passage hole 22.
Then, it becomes the exhaust air from the electric blower 16 and is discharged to the outside air from the exhaust port 29 provided in the cleaner main body 15.

At the mating portion 30 of the partition 23 having the air passage hole 22 at the right side of the main body case 20 and the left side of the main body case 21, that is, on the parting line of the die, the male and female dies are not forcibly pulled out. An L-shaped rib 31 is provided so as not to become uneven. Note that the L-shaped rib 31 may have a bent portion and be substantially L-shaped.

In front of a partition 23 having an air passage hole 22,
A filter 32 for preventing dust from entering the electric blower 16 is provided. Slit 32 on filter 32
a is provided, and the slit 32 a of the filter 32 enters the L-shaped rib 31 to lock the filter 32.

Therefore, the filter 32 can be supported without providing a separate component for supporting the filter 32 as in the prior art, and the filter 3 can be formed with a simple structure on a mold.
2 can be performed more reliably than a simple straight rib.

2 and 3, a guide rib 33 covering the outer periphery of the filter 32 is integrally provided on a partition wall 23 having an air passage hole 22 in front of the main body case right 20 and the main body case left 21. Have been.

Therefore, it is possible to prevent dust from entering from the end of the filter 32, to prevent the backlash of the filter 32, and to support the filter 32. Also, in FIGS. In front of the air hole 2
A support rib 34 for supporting the filter 32 is integrally provided on the partition wall 23 having the support ribs 2.
A slit 32b is provided on the side of the filter 32 opposite to the filter 32, and the slit 32b of the filter 32 enters the support rib 34 to support the filter 32.

Therefore, the filter 32 is supported by the main body case right 20 and the support rib 34 formed integrally with the main body case left 21, so that the filter 32 can be supported without increasing the number of parts. Since the support ribs 34 can also have a very simple mold configuration in resin molding, the filter 32 can be supported at low cost.

[0023]

According to the first aspect of the present invention,
A partition partitioning the dust collecting chamber and the electric blower chamber is formed integrally with the main body case composed of a plurality of parts, and substantially L protruding toward the dust collecting chamber near the joint of the plurality of main body cases with the partition. A substantially rib-shaped rib is inserted into a cutout provided in the dust-proof filter, and the dust-proof filter is locked. Can hold the filter.

According to the invention described in claim 2 of the present invention, the partition wall having an air passage hole is formed at the front part of the right side of the main body case and the front part of the left side of the main body case so as not to be forcibly removed from the mold structure.
Since the L-shaped rib is provided, and the tip of the L-shaped rib protrudes from the coupling portion of the main body case, and the L-shaped rib is used to hold the filter, without providing another component,
The filter can be locked with a simple configuration.

According to the invention of claim 3 of the present invention, since the guide ribs for covering the outer periphery of the filter are integrally provided on the partition wall having the air passage hole, dust intrusion from the filter end can be prevented, and The play of the filter can be stopped and the filter can be supported.

According to the invention of claim 4 of the present invention, since the support rib for supporting the filter is integrally provided on the partition wall having the air passage hole, the filter can be provided without providing another portion or another component. Support can be ensured with an inexpensive configuration.
