Description

[Detailed explanation of the idea] The present invention relates to a main body case for a vacuum cleaner.

In a conventional vacuum cleaner, as shown in Fig. 7, the inside of the main body case a is divided into a storage chamber C in which various electrical components such as an electric blower are installed, and a dust collection chamber d by a partition wall. Each chamber had an opening at the top.

However, in this case, the cylindrical intake port f1 formed in the front wall e
There was a problem in that the ventilation holes g in the partition wall and the exhaust holes i formed in the rear wall were undercuts, making it impossible to form by punching the top and bottom of the mold, resulting in poor productivity.

In other words, in this case, as shown in Fig. 8, in addition to the upper die j and the lower die, slide cores 1°m and n for the cylindrical intake rotary 1 ventilation groove g1 exhaust port i type guide were specially required. .

The present invention aims to eliminate such conventional drawbacks, and one embodiment thereof will be described below with reference to the drawings.

In Figures 1 to 6, 1 is the main case of the vacuum cleaner;
This interior is divided into a dust collection chamber 3 which stores a dust collection bag 2 through a partition wall 1a, and a storage chamber 6 which stores an electric blower 4, a foot power switch 5, etc.

As shown in FIG. 4, the dust collection chamber 3 and the storage chamber 6 of the main body case 1 are opened at opposing upper and lower surfaces, and each opening is closed by a separately formed upper lid 7 and a back M8. It's Nishide.

A substantially annular rib 9 is provided in the dust collecting chamber 3, and an attachment storage chamber 1 is opened at the top along with the dust collecting chamber 3.
0 is the formation.

By the way, the front wall 1b, the partition wall 1a, and the rear wall 1c of the main body case 1 are inclined, so that the dust collection chamber 3
The storage chamber 6 is set in an inclined shape so that its opening side is enlarged.

17 is a hole formed in the front wall 1b, 18 is a vent hole formed in the partition wall 1a, and 19 is an exhaust port formed in the rear wall 1c.

The back cover 8 is integrally fixed to the main body case 1, but the top cover 7 can be attached and detached by means of a hole 12 provided in the handle 11 of the main body case 1 and a buckle 15 fitted into a through hole 14 of the partition wall 1a. It is.

Reference numeral 16 designates an inlet pipe protruding into the dust collection chamber 3, which is connected to a hole 17 formed in the front wall 1b of the main body case 1.
It should be installed on.

In the above configuration, in this vacuum cleaner, the opposite sides of the dust collection chamber 3 and the storage chamber 6 of the main body case 1 are opened, and each side is sloped so that the opening sides are enlarged. can be molded by punching the top and bottom of the mold.

That is, in this case, as shown in FIGS. 5 and 6, the upper mold 2
Hole 1 is formed by opening the lower mold 21 in the vertical direction.
7. The ventilation port 18, the exhaust port 19, and the through hole 14 can be formed by cutting out the upper and lower molds 20 and 21.

Note that, as described above, the suction port cylinder 16 is formed separately from the main body case 1 and is attached later, so that it does not interfere with the upper and lower removal of the mold.

On the other hand, in this embodiment, the dust collection chamber 3 is provided with an attachment storage chamber 10;
0 has an open top surface like the dust collecting chamber 3, so it has the advantage that it can be molded at the same time as the dust collecting chamber 3 by punching the top and bottom of the mold.

Further, since the attachment storage chamber 10 is provided in the dust collection chamber 3, there is an advantage that various attachments stored inside can be easily taken out by removing the top cover 7.

As described above, according to the present invention, the main body case can be molded by punching the top and bottom of the mold, and productivity can be greatly improved, which has great practical value.
