Description

Water wash vacuum cleaner

The present invention relates to a water washing vacuum cleaner that collects and removes water using a washing power of water without using a filter such as a dust bag that filters dirt and dust, and more specifically, into the cleaner by the suction power of the vacuum cleaner. The induced air, dust and dirt are sprayed in the circumferential direction with respect to the water stored in the cleaning chamber of the cleaner to generate rotational force and rotate at high speed with the water while the dust and dirt in the air are adsorbed to the water and absorbed Water and dirt are separated and removed by the clone, and only the clean air is discharged, and the water (liquid) spilled on the floor is related to a water washing vacuum cleaner.

In general, the vacuum cleaner is to suck the air and dirt by the suction power of the blower to collect the dust and dirt using a filter, a dust bag, a dust bucket, and to filter the air to be discharged.

However, in order to collect fine dust by using a compact filter, such a conventional vacuum cleaner has a large blowing resistance, so that the size of the filter eye can not be set below a certain size in order to maintain a proper suction force. Smaller dust passes through the cleaner and diffuses into the room, making the indoor air worse. In particular, a large amount of fine powdery dirt can block the filter in a short time, making it difficult to vacuum. .

In particular, the filter accumulates dust until the next exchange, which causes the indoor air to be rather polluted, causing the cleaner motor to become overloaded and cause a breakdown, and the hassle of discarding the dust bag or playing away the collected dust. And the purchase of dust bags and costs.

In addition, commercially available vacuum cleaners are available for sale, but these vacuum cleaners can be equipped with wet motors to inhale water. However, the inside of the vacuum cleaner is not different from other vacuum cleaners, so dust and dirt in the air are not washed at all. However, the filter does not have a normal water cleaning function such as wet with water.

In addition, the water filter cleaner, filed as Utility Model 1999-002420, adopts a method of simply passing air and dirt introduced into the water stored inside the cleaner, but it is sucked at a considerable wind speed (about 40-50 m / sec). Due to the large kinetic energy of the air, a large passage is formed in the water, so that dirt or dust in the air passes through most of it as it is, and water is also sucked into the impeller and the motor, and operation is not possible, and it is difficult to expect a water filter function.

The present invention was devised to solve the existing problems as described above, the technical purpose of the present invention is to collect and remove the dirt in the vacuum cleaner without the use of filters, dust bags, dust bins, and excellent cleaning power of water and It effectively collects and removes fine dust to discharge only clean air, and makes it easy to discard dirty water and dirt, providing a hygienic and convenient water cleaning vacuum cleaner that eliminates the inconvenience of filter clogging, replacement and dusting. will be.

Another object of the present invention is a natural result of having a function of separating and storing the water inside the cleaner body, to enable the cleaning of the water on the floor, and to provide a cleaner having a function of cleaning by sucking the liquid flowing on the floor, etc. will be.
