The present invention relates to a robot cleaner in which washing water is scattered, and in particular, by installing a storage tank and a pump containing washing water, the cleaning water is supplied to the bottom when the cleaning operation is performed, so that foreign matters stuck to the bottom surface can be removed. The present invention relates to a robot cleaner in which washing water is scattered to prevent dust from being blown during the cleaning operation so that an effective cleaning operation can be performed.

In general, a robot cleaner is a device that automatically cleans an area to be cleaned by suctioning foreign matter such as dust from the ground while driving itself in the area to be cleaned without a user's operation.

The robot cleaner according to the related art has a cleaner body constituting a predetermined space, a drive device including a plurality of rollers protruding from the bottom of the cleaner body, and a motor for applying a driving force to the rollers, a suction port and a blowing air protrusion protruding from the bottom of the cleaner body. It includes a suction device consisting of a fan, a container, and a sensor for detecting a cliff and an obstacle in a traveling direction of the cleaner body to change the traveling direction.

As a result, the cleaner main body moved by the driving device removes the foreign matter accumulated on the bottom surface by the suction device.

However, since the robot cleaner according to the prior art collects the foreign matter only by the suction device without a separate device, it is difficult to suck the foreign matter fixed on the floor or the foreign matter larger than a certain size into the container. There is a problem that foreign matter remains on the bottom surface even after.

In order to solve this problem, a robot cleaner equipped with a brush that makes physical contact with foreign objects has emerged, but a robot cleaner equipped with a brush can easily collect foreign substances fixed on the floor or foreign substances of a predetermined size. Since it is difficult to collect the fine dust flying in the air, after a certain time after the cleaning operation is finished there is a problem that the dust scattered in the air is settled on the floor to remove foreign matters.

The present invention has been made to solve the above problems of the prior art, by applying a physical contact to the foreign matter fixed on the bottom surface or a foreign matter of a predetermined size, so that the foreign matter can be easily suctioned while moving to the inlet side It is an object of the present invention to provide a robot cleaner in which a small amount of foreign matter is collected in the wash water and falls on the bottom surface so that the washing water can be easily sucked by the suction device by scattering the washing water on the bottom surface.

The robot cleaner in which the washing water is scattered according to the present invention for solving the above problems forms a predetermined space, and has a vacuum cleaner main body having a suction port and a discharge port formed on a bottom thereof, a driving device installed on the vacuum cleaner main body, and installed inside the suction port. It is characterized in that it comprises a suction device for collecting the foreign matter, and the injection device is installed inside the discharge port so that the washing water is scattered to the bottom.

Hereinafter, an embodiment of a robot cleaner in which washing water is scattered according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a plan view illustrating a robot cleaner in which washing water is scattered according to the present invention, and FIG. 2 is a bottom view of a robot cleaner in which washing water is scattered according to the present invention, and FIG. A robot cleaner is shown in cross section.

The robot cleaner in which the washing water is scattered according to the present invention comprises a cleaner body 10 having a predetermined space, and having a suction port 12 and a discharge port 14 formed on one side of a bottom thereof, and a driving device installed in the cleaner body 10 ( 20), the suction device 30 is installed inside the cleaner body 10 to collect the foreign matter, the spraying device 50 is installed on the cleaner body 10 so that the washing water is scattered to the bottom, and the It is rotatably installed on the bottom of the cleaner body 10 is configured to include a brush 40 for applying a physical contact to the foreign matter.

When the cleaner body 10 is moved by the driving device 20, the foreign matter is introduced into the container 32 by the suction device 30, and the brush 40 is rotated so that the foreign matter adhered to the bottom surface. In addition, foreign matters of a predetermined size or more are moved to the inlet 12, so that foreign matters are easily collected.

In addition, the injector 50 may include a storage tank 52 installed inside the cleaner body 10 and containing a washing water, and a supply pipe 54 connected between the storage tank 52 and the discharge port 14 from the storage tank 52. The pump 56 is installed on one side of the supply pipe 54, so that the washing water flows along the supply pipe 54 by the pump 56 during the cleaning operation, and flows to the bottom surface through the discharge port 14. Scattered.

At this time, the washing water scattered by the injector 50 is sprayed with a small amount so as not to accumulate on the bottom surface so that only foreign matter in the air can be adsorbed to fall on the bottom surface to prevent foreign matters from flying in the air during the cleaning operation. , The foreign matter flows to the suction port 12 side to be introduced into the container 32 by the suction device 30.

Figure 4 is a side cross-sectional view showing another embodiment of a robot cleaner in which the washing water splashes according to the present invention.

Another embodiment of the present invention includes a cleaner body 10, a driving device 20, a suction device 30, an injection device 50, and a brush 40 as compared to an embodiment. The same thing, but the mop 60 is detachably installed on the bottom rear portion of the cleaner body 10 is characterized in that.

As a result, when the washing water scattered by the injection device 50 is supplied to a predetermined amount or more, the mop robot cleaner may be implemented since the washing water remaining on the bottom surface may be cleaned.

Looking at the operation of the robot cleaner in which the wash water according to the present invention configured as described above is scattered as follows.

First, when the user presses the operation unit 16, the cleaner body 10 is moved while the driving device 20 is rotated, and foreign matter is sucked from the bottom surface while the suction device 30 is driven, and the brush 40 is rotated. By the physical contact is applied to the foreign matter fixed on the floor or a foreign matter of a predetermined size or more so that the foreign matter can be easily collected while moving to the suction port (12) side.

In addition, when the injection device 50 is driven, the washing water freshly stored in the storage tank is injected by the pump 56 along the discharge port 14 to the bottom surface of the cleaner body 10, so that foreign matters blowing in the air are collected in the washing water and bottom Since it falls to the surface is introduced into the container 32 by the brush 40 and the suction device (30).

As a result, a clean cleaning operation may be performed in which foreign matters remain on the bottom surface, and according to another embodiment, since the cleaner body 10 moves in the state in which the mop 60 is in contact with the bottom surface where the washing water remains. Mop cleaning effect is generated.

The robot cleaner in which the washing water is scattered according to the present invention configured as described above is installed by the spraying device to allow the washing water to be scattered to the front of the cleaner main body, and the foreign matters blown by the air are collected by the washing water being scattered and fall to the bottom surface. Since it is introduced into the container by the brush and the suction device, it prevents foreign matters from being blown out during the cleaning operation, so it is possible to effectively collect all the foreign matters stuck on the floor and the airborne foreign matters. There is an advantage that clean cleaning work can be prevented.
