Exhaust air feedback robot cleaner equipped with a disinfectant anion generator

Abstract

Disclosed is an exhaust air feedback robot cleaner equipped with a disinfectant anion generator, including a suction motor to intake not only air but also dust from a to-be-cleaned surface through a suction unit installed at the bottom surface and a dust collector to trap dust so as to allow dust-free air to be discharged via the suction motor. In the robot cleaner, the disinfectant anion generator emits disinfectant anions to disinfect the air having been discharged via the suction motor, a spray nozzle installed at the front end of an intake port of the robot cleaner sprays the disinfected air toward the cleaning surface through an exhaust air feedback unit so that the dust on the to-be-cleaned surface may be scattered and disinfected, and finally the air, together with the dust, is sucked in by the suction motor and circulated again to the exhaust air feedback unit.

Description

TECHNICAL FIELD[0001]The present invention relates to an exhaust air feedback robot cleaner equipped with a disinfectant anion generator, and more particularly to an exhaust air feedback robot cleaner equipped with a disinfectant anion generator which supplies anions emitted from an anion generator to exhaust air emitted from a suction motor or an impeller installed in a robot cleaner and circulates and sprays the anion-containing exhaust air to a surface to be cleaned with a spray nozzle unit, so that it can disinfect dust in the robot cleaner as well as the surface to be cleaned.BACKGROUND ART[0002]Robot cleaners generally travel under their own propulsion all around a section to be cleaned and suck foreign matter such as dust from the floor without the intervention of a user, automatically cleaning the section to be cleaned. Moreover, when the power of the robot cleaner has almost run out, it moves to a charging position by itself so that the power can be charged. After that, whe...

Benefits of technology

[0011]Another object of the invention is to provide an exhaust air feedback robot cleaner equipped with a disinfectant anion generator which increases the anion content in the circulating air to be sprayed to a surface to be cleaned by discharging anions to the circulating air by an exhaust air circulation mechanism, thereby enhancing the effect of disinfecting the surface to be cleaned.

[0022]According to the invention, when the anion-containing circulating air is sprayed from the front end of the suction port by the spray nozzle, an air curtain may be formed. Thanks to this mechanism, the robot cleaner has many effects, for example, it is possible to prevent foreign matter from being scattered outside the robot cleaner.

Problems solved by technology

However, when the foreign matter adheres to the surface to be cleaned or to the surface of a carpet, it is usually found that the robot cleaner just travels along the traveling pattern without perfectly removing the foreign matter.

Moreover, the size and weight of the robot cleaner are limited due to the places where the robot cleaner will be used.

Accordingly, it cannot be equipped with a suction motor of a large capacity, so that it is difficult to increase the suction force.

Therefore, foreign matter is not likely to be perfectly removed by the robot cleaner.

Such a problem is especially serious in vacuum suction robot cleaners.

However, it is difficult to remove the foreign matter sticking to the other areas because the foreign matter in the other areas is removed only by the vacuum sucking system.

As described above, the suction and brush type is designed to complement for the drawback of the vacuum sucking system by using the brush but this is not a fundamental solution to the remaining foreign matter.

Moreover, due to the addition of the brush system, an additional part is necessary, which results in an increase in cost and causes maintenance problems.

Due to the flow of exhaust air, a problem arises in that the foreign matter that has accumulated near the robot cleaner is scattered around.

However, since the scattering dust remains in the air after the removal of the foreign matter, there are various problems such as having a negative impact on a user's respiration.
