The present invention relates to a robot cleaner, and more particularly, to a robot cleaner having an air cleaning function.

In general, a robot cleaner is a device that automatically cleans an area to be cleaned by inhaling foreign substances such as dust from the floor while driving the area to be cleaned by a user without an operation. However, the conventional robot cleaner does not perform the air cleaning or air purifying function, but merely cleans dust or dirt on the floor, but in recent years, the public's interest in health is increasing, especially yellow dust or Under the influence of Severe Respiratory Syndrome (SARS), consumers' desire to breathe a pleasant environment and air has increased.

Such a conventional robot cleaner which does not have a conventional air cleaning or air purifying function simply collects and cleans dust or dirt on the floor, and there is no function to purify the air in the cleaning space. There is a burden. In addition, since the robot cleaner itself is not equipped with an air purifying function, when the dust on the floor is not completely sucked into the suction port, the air in the cleaning space becomes more turbid, which may cause a user's health problem.

In order to solve the above problems, an object of the present invention is to provide a robot cleaner having an air cleaning function capable of purifying the air in the cleaning space at the same time or independently while cleaning.

In order to achieve the above object, the present invention provides a cleaner body having an upper cover for opening and closing an upper / lower body and an upper portion of the upper body; A driving unit installed at the lower body to drive the cleaner body along the surface to be cleaned; A cleaning unit installed on the lower body to suck dust of a floor; An air cleaning unit installed in the upper body to inhale and purify the air in the space where the cleaner body is present; And a control unit disposed inside the lower body and controlling the driving unit, the cleaning unit, and the air cleaner.
