Abstract

According to the present invention, an inlet and an exhaust port are disposed on a surface to be cleaned in a conventional vacuum cleaner including a suction port, a dust collector, a filter, an electrical suction unit, and an exhaust port, and the air sucked by the electrical suction unit during operation passes through the dust collector and the filter. Exhausted through the exhaust vent, the exhaust air is fed back to the inlet, including dust and dirt particles present on the surface to be cleaned, so that the dust on the surface to be cleaned is removed from the dust collector, but almost no air is discharged outside the cleaner. The present invention relates to a vacuum cleaner that prevents contamination of indoor air by fine dust that cannot be filtered by a filter.

Description

Vacuum cleaner

A typical vacuum cleaner is composed of a suction port, a dust collector, a filter, an electrical suction unit and an exhaust port, and generates an under pressure state in the suction port and the dust collector by the electrical suction unit during operation. The dust and dirt particles present on the surface to be cleaned are removed through the intake port in the dust collector under the influence of the pressure under pressure, and through the filter, the air in which the dust and dirt particles are filtered out is discharged to the exhaust port. At this time, the discharged air contains particles smaller than the particles that can be removed by the filter to become a pollution source polluting the room, and the air discharged through the discharge port disperses the surrounding dust in the room to contaminate the indoor air. In order to solve the above problems, a technique of improving the performance of the filter to clean the air discharged through the exhaust port has been applied.However, since there is an exhaust port in the vacuum cleaner to completely remove the air pollution, It is difficult.

The present invention aims to provide a vacuum cleaner in which the disadvantages as described above are avoided. In detail, in a conventional vacuum cleaner including a suction port, a dust collector, a filter, an electrical suction unit, and an exhaust port, the suction port and the exhaust port are disposed close to each other, and the electrical suction unit is kept under pressure by the electrical suction unit during operation. And the sucked air is discharged through the exhaust port through the purifier and the filter, and the discharged air is fed back to the inlet including the dust and dirt particles present on the surface to be cleaned again, and the dust and dirt particles are removed from the dust collector, Only clean air is exhausted again through the exhaust vents. Repeating this process, the dust on the surface to be cleaned is removed from the dust collector, but since the air is hardly discharged to the outside of the cleaner, it prevents contamination of indoor air by fine dust that cannot be filtered by the filter.

In order to realize the above technical problem, the present invention includes a suction port, a dust collector, a filter, an electrical suction unit and an exhaust port, and the air suctioned to the suction port by the electrical suction unit during operation by arranging the suction port and the exhaust port in close proximity to the dust collector and the filter. Is discharged through the exhaust port, and the discharged air is configured to feed back to the inlet including dust and dirt particles present on the surface to be cleaned again. This configuration will be described in detail in the preferred embodiment.
