Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vacuum cleaner using a long hose.

Conventionally, there are vacuum cleaners that use a long hose of up to 10 rr as a suction hose to clean large rooms.
As described in Japanese Patent No. 127473, a long hose is stored in a wound state within a main body case.

Furthermore, in order to effectively utilize the entire length of this long hose, a hose outlet is cut out in the side wall of the main body case from the top to the bottom. In a vacuum cleaner using such a long hose, it is difficult to install a dust collection case inside the main body case, and the above-mentioned Japanese Patent Application Laid-Open No. 49-12747
In Publication No. 3, a cyclone system is used to removably provide a dust collection case at the bottom of the main body case.

However, when throwing away the dust, it is not easy to remove the dust collection case. The present invention has been made in view of these points, and an object of the present invention is to provide a vacuum cleaner in which the dust collection case can be easily attached and detached, and airtightness can be easily maintained.
A first embodiment of the present invention will be described with reference to FIGS. 1 to 4.

Reference numeral 1 denotes a main body case with an opening at the top, and inside the case there is a hose storage chamber 5 in which elastic suction hoses 4 are stored while being wound in a helical manner by having two large and small annular walls 2 and 3 facing each other. A connecting portion 6 for holding one end of the suction hose 4 is formed near the bottom of the hose storage chamber 5.

Next, inside the hose storage chamber 5, there are formed an electric chamber 9 having an exhaust hole 7 on the bottom surface and in which an electric blower 8 is placed, and a dust collection chamber 10 located above the electric chamber 9.

The connecting portion 6 and the dust collection chamber 10 are connected by an air passage 11, and an annular packing 13 is provided around the opening end 12 of the air passage 11 on the exhaust side. Further, the dust collection chamber 10 and the electric power chamber 9 are connected by an air passage 15 sealed by a backing 14. Next, a dust collecting case 16 is removably attached to the dust collecting chamber 10 from above, and a lid 17 covering the upper part is attached to the dust collecting chamber 10 so as to be openable and closable.

The dust collection case 16 has an inlet 18 connected to the air passage 11 and an outlet 19 connected to the air passage 15. Further, the dust collection case 16 houses a dust collection bag 20 having air permeability. A mounting plate 20 is fixed to the opening edge of the dust collection bag 20, and the suction port 1 is located at the center of this mounting plate 21.
A suction port 22 facing 8 is formed. The mounting plate 21 is removably held between the inner surface of the dust collection case 16 and a U-shaped support plate 23 with an upward opening and connected to the inner surface. Furthermore, a flange 26 is provided on the opening edge of the dust collecting case 16 to which the lid 25 is joined while being sealed by a backing 24, and a locking piece 2 formed on the lid 25.
An engagement hole 28 that engages with 7 is formed. and,
The inner surface of the dust collection chamber 10 has a shape that gently slopes inward toward the bottom to press the dust collection case 16;
A guide portion 2 made of ribs that aligns the suction port 18 with the open end 12 of the air passage 11 and presses it against the backing 13.
9 is formed. Further, a lid 30 that covers the entire upper surface of the main body case 1 is attached to the upper part of the main body case 1 so as to be openable and closable. In such a configuration, the suction hose 4 is pulled out, an extension pipe or a suction port (not shown) is connected to the end of the suction hose 4, and the electric blower 8 is driven. As a result, outside air containing dust is sucked into the dust collection bag 20 from the suction hose 4, and the air purified by the filtering action of the dust collection bag 20 passes through the air path 15 and is exhausted from the exhaust hole 7. After use, the suction hose 4 can be simply wound spirally along the annular walls 2, 3 and stored.

At this time, by driving the electric blower 8 and manually closing one end of the suction hose 4, a shrinking force is applied to the suction hose 4 due to negative pressure, which allows the suction hose 4 to be stored extremely easily. be able to. The storage arrangement is regular, and the entire suction hose 4 can be stored therein, and cracks can be prevented from occurring due to locally small bending radii. Moreover, since the dust collection chamber 10 and the electric dust 9 are arranged by effectively utilizing the dead space inside the annular hose storage chamber 5, the whole can be made extremely compact. Furthermore, dust collection chamber 1
0, the dust collecting case 16 is guided by the guide part 29 and is brought into close contact with the backing 13, the suction port 18 is also aligned with the opening end 12 of the air passage 11, and the dust collecting case 16 is guided by the guide part 29 and is brought into close contact with the backing 13, and the suction port 18 is also aligned with the opening end 12 of the air path 11.
9 is sealed by the backing 14, thus preventing leakage of the suction airflow. In particular, it is hygienic because there is no airflow that is not purified by the dust collection bag 20 and leaks.
Next, a second embodiment of the present invention will be explained based on FIGS. 5 and 6.

The same parts as in the previous embodiment are designated by the same reference numerals, and the description thereof will be omitted. A vertically elongated hose outlet opening 31 is formed on the front outer surface of the main body case 1 and extends from the upper end of the hose storage chamber 5 to a portion near the bottom. Therefore, when cleaning a large room, the suction hose 4 is pulled upward from the bottom of the hose storage chamber 5, and the suction hose 4 is pulled out from the hose storage chamber 5 without the need for it to drip onto the floor again. It can be extended onto the floor through the outlet opening 31.

Therefore, the effective length of the suction hose 4 can be increased and a wide area can be cleaned. Since the present invention is configured as described above, a long suction hose can be easily and regularly wound and stored in the annular hose storage chamber.
It is possible to store all the suction hoses and prevent the occurrence of cracks due to locally small bending radius, and by arranging the dust collection chamber and the electric chamber inside the annular hose storage chamber, The entire structure can be made extremely compact by effectively utilizing the dead space, and furthermore, a guide portion is provided in the dust collection chamber to connect the suction port of the dust collection case to the open end of the air passage from the suction hose while closely contacting the dust collection chamber. This makes it possible to prevent airflow containing dust from leaking and improve hygiene.
