Description

Wet mop robot vacuum cleaner}

The present invention relates to a wet-mop robot cleaner, and more particularly, to remove foreign matter on the floor through a mop means mounted on the lower part of the robot body, as well as to suck dust on the floor through an externally detachable cleaning means. It is about a robot vacuum cleaner that can mop.

In general, a vacuum cleaner is a device for cleaning indoor dust and the like, and the vacuum cleaner includes a vacuum cleaner that a user directly holds and cleans, and a robot cleaner that cleans by self-driving.

Among the vacuum cleaners described above, a robot cleaner includes a cleaning module provided inside the cleaner body, a driving module provided under the cleaner body, and a power supply provided inside the cleaner body.

Further, the robot cleaner moves to a dusty cleaning area while traveling by itself by a drive module provided at the lower part of the cleaner body, and cleans by sucking in dust while sucking in surrounding air by the cleaning module.

On the other hand, the robot cleaner as described above uses a mop plate equipped with a water container at the lower part of the cleaner body so that mop can be cleaned during the cleaning process.

However, conventional robot cleaners are designed to clean by sucking foreign substances from the floor, so there is a problem in that they can clean cleanly while removing contamination from the floor, as well as contaminating the surroundings during the suction of foreign substances.

In addition, the conventional robot cleaner has a problem of not only having difficulty in sucking metal parts such as needles and pins located on the floor, but also damaging the floor when the metal parts are fixed to the mop plate.

At this time, the wet mop 350 can also remove foreign substances on the floor through the water supplied through the distributor 340 of the mop plate 330.

The cleaning means 400 is mounted on the outer surface of the robot body 200.

That is, the cleaning means 400 is equipped with a plurality of cleaning modules on the outer surface of the robot body 200, sucks foreign substances and dust from the floor surface when the wet-mop robot cleaner 100 moves, and stores them inside.

And, the cleaning module constituting the cleaning means 400 includes a body coupling case 410, a contact member 420, an outer case 430, a housing 440, and a driving unit 450.

The body coupling case 410 is disposed around the outer surface of the robot body 200 .

In addition, the body coupling case 410 has fitting holes 411 formed in the vertical direction at intervals therein, and a close contact member support groove 412 is formed on the inner circumferential surface.

That is, the body coupling case 410 is formed in a hollow shape so that the robot body 200 can be accommodated therein while being formed in a shape corresponding to the outer surface of the robot body 200, and the robot body 200 is formed on the inner surface. ) To support the close contact member 420 in close contact with the close contact member support groove 412 is formed, and a fitting coupling hole 411 for coupling the outer case 430 is formed at intervals therein.

In addition, the body coupling case 410 may be formed in various shapes according to the shape of the robot body 200, and in the present invention, the body coupling case 410 is formed in a hollow cylindrical shape. Let me explain with an example.

The close contact member 420 comes into close contact with the robot body 200 .

That is, the outer surface of the contact member 420 is supported in the contact member support groove 412 and the inner surface is in close contact with the outer surface of the robot body 200 .

Here, the reason why the contact member 420 is formed of rubber or silicon is to increase fixing force while enabling deformation according to the shape of the robot body 200 .

The outer case 430 is composed of a plurality and is detachably mounted to the body coupling case 410 .

In addition, the outer case 430 has a fan-shaped fitting protrusion 431 formed on the inner circumferential surface is fitted into the fitting hole 411 of the body coupling case 410, and the support wall is vertically along the edge end. 432 is formed, and a horizontal support 433 in which a lower through hole 434 is formed is formed.

That is, the outer case 430 is coupled or separated through the body coupling case 410 and the fitting protrusion 431, and accommodates the housing 440 through the support wall 432 and the horizontal support portion 433. be able to

The housings 440 are mounted on the outer case 430 respectively.

That is, the housing 440 is mounted in a space formed between the support wall 432 and the horizontal support part 433 constituting the outer case 430 .

In addition, the housing 440 has a suction hole 441 formed at the bottom to suck in dust or foreign substances located on the floor, and dust or foreign substances introduced through the suction hole 441 pass through the passage 443. A collection space 442 accommodated through is formed, an air circulation hole 444 is formed at the top, and a drive unit mounting space 445 mounted therein corresponding to the air circulation hole 444 is formed.

That is, the housing 440 removes dust or foreign matter through the passage 443 through the suction hole 441 when the wet mop robot cleaner 100 moves through the suction force of the driving unit 450 mounted in the driving unit mounting space 445. After passing through, it is collected in the collection space 442.

Here, it is natural that an opening and closing door is mounted on one side of the housing 440 where the collection space 442 is formed to remove foreign substances or dust accommodated in the collection space 442 .

The driving unit 450 is mounted in each driving unit mounting space 445 .
