Description

DETAILED DESCRIPTION OF THE INVENTION An object of the present invention is to provide a vacuum cleaner suitable for hospitals, clean rooms, etc.

Conventionally, vacuum cleaners used in general households have a pre-filter of 1 m and a main filter of Ti1411.
The dust was filtered out and the degree of purification of the tJl air was at a level that was acceptable. However, in reality, a considerable amount of fine dust remained in the exhaust gas, making it unsuitable for cleaning hospitals and clean rooms.

The present invention significantly increases the degree of purification of exhaust gas by improving the filter, and examples thereof will be described below with reference to the accompanying drawings.

In FIGS. 1 and 2, a fan motor 6 is attached to a partition wall 3 having a single ventilation hole 2 via a cushioning material 4, and
This is a vacuum cleaner body in which a ventilation cylinder 6 made of a porous material such as a U1 hunting plate or wire mesh is connected to the upper ill Kesen, and the JIJI air side of the fan motor 6 and the ventilation cylinder 6 are connected by a wind cylinder 7. . The ventilation cylinder 6 has a large diameter part 6a at the bottom, a small diameter part 6b at the top, and the top is an air-impermeable wall. li: Lower part of the vacuum cleaner body 1, suction of the fan motor 5 (intake port 1 which is removably connected to 1111 via a buckle 9, and into which the port 10 is inserted 1 on the 41111 side)
1, a dust case each provided with wheels 12 at the bottom;
13 is an intake side filter whose peripheral edge is sandwiched between the side opening end of the dust case 8 and the partition wall 3; 14 is the small diameter i of the ventilation cylinder 6;
τ1 (ebKIM A cylindrical exhaust side pre-filter 115 made of urethane foam, which is a high-performance cylindrical exhaust filter located outside of the exhaust side pre-filter 14. It fits in with the

In the above structure, when the dust-containing air H-11 flows in through the intake port 11 and passes through the I11 filter 13, general dust is filtered out, and this dust is collected in the dust case 8. The airflow that has passed through the intake side filter 13 flows through the fan motor 6 or 1 and the wind cylinder 7, and reaches the inside of the ventilation cylinder 6.

Next, the air is ejected from the hole in the direction of the outer periphery 7/ This air flow U 1 Exhaust side pre-filter 14, Tsue Kesen high 1/1 function filter 16 Ona, 1: Bii Gogo h 16 Mountain clothing l (1) −

The reduced air flow is exhausted (1111 high 1 (when passing through the single-function filter 15, the fine dust inside it is removed once) l/
It is guaranteed to be collected within 1 hour of recording.

Therefore, the exhaust gas purification degree V1 is extremely high. Sunda exhaust J111 pre-filter-14,1',...1
When the high 4/l filter 15 is turned on and off, the noise energy therein is also attenuated, so a noise reduction effect can be expected.

Note that it is preferable to take measures to make the distribution of air flow uniform, such as by changing the opening 11 degree ratio between the 6th and 1st lower parts of the ventilation pipes.

Next, FIG. 3 shows a part of the protection tube 16 closed with a shielding plate 19, and FIG. 4 shows the end of the protection tube 16 with no holes facing each other.
FIG. 6 shows a structure in which a non-ventilated portion 20 is formed by polymerization 1 to 1. FIG.

If 7.1 is applied to 11141111, the exhaust air will not hit the workers and they will not feel uncomfortable.

As described above, the vacuum cleaner of the present invention provides the following excellent effects.
