Description

Vacuum cleaner {vacuum cleaner}

The present invention relates to a vacuum cleaner.

In a conventional vacuum cleaner, a suction chamber in which a blower is incorporated is disposed in a downstream portion of the main body, a dust collecting chamber for collecting and collecting solid matter such as dust is disposed in the upstream portion, and a connection pipe provided at one end of the hose is connected Is provided at the upstream end of the main body.

And the other end of the hose is provided with a distal end pipe having a grip portion at the time of cleaning. One end of the extension pipe is connected to the distal end pipe by a removable material, and the other end of the extension pipe is connected to a suction pipe Suction ducts are provided as removable materials.

When the conventional vacuum cleaner thus configured is used for a predetermined period of time, the solid material is accumulated in the dust collecting chamber, so that the vacuum is not properly formed in the dust collecting chamber and the dust collecting efficiency is lowered. In this case, the user manually pulls the solids accumulated in the dust chamber out of the main body.

Such solids extracting causes a problem that the user touches the abominable water by hand and is treated as a very inconvenient and cumbersome work.

A vacuum cleaner for solving such a problem is disclosed in Patent Registration No. 10-1372513 filed by the present inventor and patent registered.

In the vacuum cleaner described above, the dust outside the cleaner main body can be received in the cleaner main body by the negative pressure and can be discharged outside the cleaner main body by the positive pressure, so that the dust, However, the rotary valve is arranged below the dust collecting chamber and the dust collecting chamber, which causes the vacuum cleaner main body to be excessively large in the height direction of the main body.

A vacuum cleaner for solving such a problem is disclosed in the pending Patent Publication No. 10-2014-0097071.

The vacuum cleaner includes a plurality of pockets for rotating the dust collecting chamber and allowing one of the plurality of pockets to flow into the suction port and the suction chamber at the same time, A plurality of partition walls for partitioning the plurality of pockets are rotated while rubbing the filter or the perforated plate on one side thereof to remove the solid or sticking to the filter or perforated plate, One of the pockets circulates the solids discharge tube that discharges the solids out to the pockets which do not flow into the suction port and the suction chamber, and the solids accumulated in the dust collecting chamber are discharged through the vacuum cleaner Without the rotary valve being an air-tight opening / closing means interposed in the solids discharge pipe, Hayeoseo body to be accommodated in the collecting bag placed outside, the user can, while the aversion to clean water in which exclusion conditions as to touch by hand the accumulated solids on the filter exhaust collecting chamber out of the body.

However, the vacuum cleaner described above has a problem in that a manufacturing cost is increased due to a complicated structure for rubbing a filter or a perforated plate while one side of the plurality of partition walls is rotated.

A vacuum cleaner for solving such problems is disclosed in pending patent application No. 10-2014-96148.

In the above-described vacuum cleaner, a tubular dust collecting chamber defined by a partition wall portion and a suction chamber circulating in the dust collecting chamber are provided in the main body, an air blower is provided in the suction chamber, and a solids discharge A first flow port extending in a downward direction in a state in which both ends of the dust collecting chamber can communicate with the outside of the main body are provided in the main body so as to allow the outside of the main body and the main body to communicate with each other, A rotary opening and closing part for forcibly moving the inflowing solids toward the first flow port is provided in the dust collecting chamber, the dust collecting chamber and the suction chamber are communicated by the second flow port, and a plurality of pockets A bottleneck is provided in each of the air flow path from the suction port of the dust collecting chamber to the suction chamber, a filter is disposed in the bottleneck portion, In is to be provided with means for cleaning the filter.

However, the above-described vacuum cleaner is equipped with a filter such as a brush on the bottleneck, and filter cleaning means such as a scraper provided on the solids discharge side for cleaning the filter is provided, Thereby increasing the cost.

The present invention has a problem in solving the above-mentioned problems.

The present invention is characterized in that a tubular dust collecting chamber defined by a partition wall portion and a suction chamber communicating with the dust collecting chamber are provided in the main body and an air blower is provided in the suction chamber, A first flow port extending downward in a state in which both ends of the main body are communicable with the outside of the main body and the outside of the main body are provided in the main body so as to allow the outside of the main body to communicate with each other, A rotary opening / closing part for forcibly moving the solid material toward the first flow port is provided in the dust collecting chamber, and the dust collecting chamber and the suction chamber are communicated by the second flow port, and a plurality of pockets A filter is provided in an air flow path that passes through the filter at the suction inlet of the true and flows into the suction chamber, The above problem can be solved by providing the reverse air flow path passing through the rotor.

According to the present invention, there is provided a vacuum cleaner comprising: a dust collecting chamber having a structure simpler than the prior art and being miniaturized; and a vacuum cleaner, which is a hermetic opening / It is possible to provide an inexpensive vacuum cleaner that allows solids accumulated in the dust collecting chamber itself to be accommodated in a collecting bag disposed outside the apparatus body and allows the user to clean the filter without touching the hand with the hand.
