It relates to a robot cleaner that can maximize the amount of filling.

In more detail, in order to perform cleaning by installing a brush that is operated (rotated) by a motor in the lower front of the housing in which the starting wheels are mounted at both sides and the auxiliary wheels are mounted at the rear of the bottom. It is installed on the upper side and water (wash water) in the bucket pumped by the pump is intermittently sprayed on the brush by the solenoid valve to clean the bottom surface while the brush is wet, but the brush is inclined forward to strengthen the brushing ability. , Sewage and contaminants generated during cleaning are sucked through the Suction Suction Cap to fill the sewage tank installed separately on the upper side of the housing, and forced air by the air fan in the sewage tank filled with sewage and contaminants. To be discharged to the outside through the air jet hole formed in the dome of the housing. Intended to provide a robot cleaner.

In recent years, as the industry develops rapidly, when cleaning floors and walls of various buildings, people do not clean, but a robot for cleaning has been developed so that the robot cleaner automatically moves and cleans itself. When it is exhausted, it will move to the charging position by itself and perform cleaning after continuing charging.

Representative examples of conventional robot cleaners for automatically cleaning as described above have been proposed in Korea Utility Model Registration No. 1988283, Publication No. 2003-7473 and Publication No. 2004-52094 .

And, it is to suck the foreign matter of the floor through the suction hole and the suction unit exposed to the bottom center of the housing.

However, since these robot vacuum cleaners or vacuum cleaner robots are designed to suck and clean foreign substances on the floor, there is a limitation that the floor cannot be cleaned while removing contamination, and the dust collecting chamber is collected and stored so that the dust collecting chamber is kept clean. If it is not cleaned, the collection chamber will be closed and the collection (dust collection) function will be reduced, so the cleaning cannot be carried out smoothly. After inhaling the foreign matter, the person must perform mopping again, so the function of the robot cleaner will be reduced. There is.

Another conventional cleaning robot is known as 'a cleaning robot capable of cleaning water' of Publication No. 2004-52094.

A suction head and a steam generating port are formed between the driving wheel and the auxiliary wheel, and a mop roller is installed. A pair of brushes are installed on the suction head to maintain a perpendicular (perpendicular) angle with the floor to suck in foreign substances and to collect dust. It is designed to collect dust in the dust collection filter, and the steam generating port is to inject steam generated by the operation of the ultrasonic vibrator installed in the bucket to the floor, and the mop roller is to wipe the floor with the steam sprayed on the floor. have.

However, since the brush installed on the suction head is installed to be perpendicular to the bottom (perpendicular), the contact area is small, and the contact time between each hair and the bottom surface is short. Since the cleaning is performed by simply discharging the water vapor generated by the operation of the ultrasonic vibrator, if the vapor (water vapor) is not injected sufficiently, the foreign matter attached to the floor cannot be completely and efficiently removed unless it is decomposed or peeled off. In addition, since the mop roller is to be wiped through the floor to which the steam is injected, the mop roller is easily contaminated in a short time, so that the cleaning ability is degraded, but rather, the floor is contaminated.

The present invention is to provide an improved robot cleaner to solve the above problems.
