Definitions

  • 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.
  • 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 charted. After that, when the power has been charged, it returns to the position where the cleaning was stopped and continues to perform cleaning.
  • Such a robot cleaner is designed to remove foreign matter from a surface to be cleaned while traveling around in a predetermined traveling pattern on the section to be cleaned by itself.
  • the robot cleaner just travels along the traveling pattern without perfectly removing the foreign matter.
  • the size and weight of the robot cleaner are limited due to the places where the robot cleaner will be used. That is, the robot cleaner should be manufactured to be small and lightweight so as to move easily. 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.
  • a suction and brush type cleaner In order to resolve the problem caused by the insufficient suction force due to the use of a small motor, a suction and brush type cleaner has been put into use that combines a vacuum sucking system and a brush system.
  • a brush In the suction and brush type, a brush first pushes up foreign matter inside a robot cleaner and then the pushed-up foreign matter is sucked up by the vacuum sucking system. Accordingly, the foreign matter on the to-be-cleaned surface, which can be brought into contact with the brush, can be removed. 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.
  • a suction port is located at the top of the brush. This is also one of the reasons for the suction force being weak. Accordingly, the foreign matter that could not be removed by the brush may still be left behind.
  • 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.
  • one object of the invention is to provide an exhaust air feedback robot cleaner equipped with an disinfectant anion generator that is installed in the exhaust air feedback robot cleaner, so that a surface to be cleaned or exhaust air which is to be sprayed onto the surface to be cleaned can both be disinfected.
  • 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.
  • Further object of the invention is to provide an exhaust air feedback robot cleaner equipped with a disinfectant anion generator, in which the disinfectant anion generator is installed between a suction motor and left and right passages so that anions can be sprayed onto the surface, which is to be cleaned, by suction force generated by a drive motor.
  • Yet another object of the invention is to provide an exhaust air feedback robot cleaner equipped with a disinfectant anion generator in which circulating exhaust air contains anion and air is uniformly sprayed onto a surface to be cleaned, so that foreign matter on the surface to be cleaned to be uniformly dispersed and the effect of disinfecting both the surface to be cleaned and the foreign matter can be enhanced.
  • Yet a further object of the invention is to provide an exhaust air feedback robot cleaner equipped with a disinfectant anion generator which makes foreign matter on a surface to be cleaned to escape from the surface by the action of circulating exhaust air and prevents the escaping foreign matter from being scattered, thereby being capable of effectively removing the foreign matter and enhancing the efficiency of disinfection.
  • Yet still further object of the invention is to provide an exhaust air feedback robot cleaner equipped with a disinfectant anion generator in which when circulation of exhaust air is applied to a robot cleaner, a circulation path of a suction air is modified so that the exhaust air can contain anions, which results in an enhanced disinfecting effect and an improved circulation path for the exhaust air.
  • the present invention relates to a robot cleaner in which foreign matter on a surface to be cleaned is sucked along with air through a suction unit provided at the bottom surface of the robot cleaner by a suction motor, the sucked foreign matter is collected by a dust collector, and the dust-free air is discharged through a drive motor, in which the air having been discharged through the suction motor is disinfected by disinfectant anions discharged from the disinfectant anion generator, the anion-containing air is sprayed, toward the surface to be cleaned by a spray nozzle installed at a front end of a suction port of the robot cleaner, through an exhaust air circulating unit so that foreign matter on the to-be-cleaned surface can escape from the to-be-cleaned surface and can be disinfected, and finally the air is sucked along with the foreign matter by the drive motor so as to be circulated into the exhaust air circulating unit.
  • the disinfectant anion generator is connected with the exhaust air circulating unit of the exhaust air circulation type robot cleaner so that the air sucked by the exhaust air circulating unit may contain anions. After that, the anion-containing air is sprayed toward the surface to be cleaned and is returned to be circulated. In this way, the anion content in the circulating air is continuously increased, and as a result the disinfection efficiency inside and outside of the robot cleaner is improved.
  • the disinfectant anions are discharged by strong air circulation force of the circulating exhaust air, the effect of disinfecting the surface to be cleaned is enhanced. Therefore, floating substances such as dust mites which have been hidden in a carpet or the like can be removed, improving the residential environment.
  • the invention can achieve both the efficient removal of foreign matter by the circulation of exhaust air and the disinfection and removal of viruses, germs, and bacteria at the same time by performing a cleaning operation once.
  • foreign matter is sucked and removed by two kinds of removal mechanism, that is, the spraying force of circulating air and the suction force of a suction motor. Accordingly, a suction motor with a small capacity can be applied to a robot cleaner, which results in a small and lightweight robot cleaner being realized.
  • the robot cleaner 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.

  • the exhaust air circulating unit 30 is installed inside the robot cleaner 100 to send the exhaust air, from which the foreign matter has been removed by the dust collector, to the spray nozzle 50.
  • the exhaust air circulating unit 30 includes a housing 33 which is connected with the dust collector 20 and encloses the suction motor 10 therein.
  • the exhaust air circulating unit 30 further includes the left and right air passages 31 and 32 having respective one ends connected with both sides of the housing 30 so that the air passages 31 and 32 can communicate with the housing, and having the respective other ends connected with the spray nozzle 50.
  • the disinfectant anion generator 40 is installed between the housing of the exhaust air circulating unit and the left and right air passages so that the disinfectant anions can be discharged into the left and right air passages 31 and 32.
  • the disinfectant anions which have been discharged from the disinfectant anion generator, disinfect the exhaust air, which has been free from the foreign matter by the action of the dust collector 20 and which has been exhausted and moved through the left and right air passages by the action of the circulation of the exhaust air, and are then discharged to the to-be-cleaned surface from the spray nozzle 50.
