DESCRIPTION

DRAINAGE SYSTEM FOR CLEANING APPLIANCE

TECHNICAL SECTOR

The present invention concerns a manual or self-movable household cleaning apparatus. More specifically, it relates to the field of household cleaning appliances provided with scrubbing means.

BACKGROUND OF THE INVENTION

Suction devices are widely known as manual or self-moving surface cleaning devices, made up of the movable body, means of movement, either autonomous or semi-autonomous, batteries and means to recharge them. Specifically, the devices to which we refer in this document that incorporate scrubbing means are also equipped with a liquid tank (water, soapy solutions or similar), to which a sponge or mop that will be in contact with the surface is attached. to be cleaned, being generally attached to the lower part of said tank.

Document CN109452907 belongs to the state of the art, which describes a device that can be integrated into a self-moving cleaning device that includes a surface drying fabric, driven by a driving roller, which transmits a rotational movement to it. facilitate drying. However, this invention does not propose a system for draining the fabric itself, achieving better drying of the surface to be cleaned. Therefore, the device anticipated by the aforementioned document would not be of sufficient efficiency in the task for which it has been conceived.

Document CN109222795 belongs to the state of the art, the purpose of which is to provide a robotic cleaning, scrubbing and drying device. The cleaning device includes a rectangular box body, the upper part of the body is provided with an opening and a cover, where the cover has a lid at the bottom. The cavity and the lower and upper edges of the body are articulated, these articulations allow different cavities to form within the body. When using the cleaning and drying device of the present invention, the Cleaning liquid must be incorporated into one of the cavities mentioned above, in this way the cleaning roller that includes said device comes into contact with this liquid and with the surface to be cleaned as a result of its own rotational movement. However, in this document it is not explained that it includes any system for draining or drying the clean surface immediately, so this surface cannot be walked on until the water or liquid used to clean it is dried by evaporation, this device The cleaning device also does not have a cavity in which it is capable of filtering impure water after cleaning.

Document KR101654015B1 also belongs to the state of the art, which refers to a cleaning robot that can improve the effectiveness of the contact of scrubbing accessories on a cleaning surface. Specifically, the mop of the robot and / or cleaning device described in this document is formed with a specific thickness and diameter, allowing a clear cleaning to be carried out, improving adherence to the surface to be cleaned. This robot cleaner does not include any drying or liquid deposition system, so the surface that is effectively cleaned remains damp and can easily get dirty again.

Finally, document CN109452907A that describes a mop mechanism applied to an automatic cleaning robot belongs to the state of the art. The mop mechanism comprises a mounting bracket, a rotation assembly, a first drive motor, a cleaning cloth, and a lifting mechanism. The rotating assembly is rotatably mounted on the mounting bracket, the caterpillar-type cleaning cloth covers the rotating assembly and rotates together with the rotating assembly, and the lifting mechanism is mounted on the robot body and used to drive the mounting bracket to raise and lower longitudinally. With the solution presented in this document, the problem of secondary contamination in the cleaning process can be solved, but it does not include a system for draining or deposition of liquids, by means of which the drying of the already cleaned surface is facilitated, by which could get dirty more easily if the surface is used before it has dried.

EXPLANATION OF THE INVENTION

Currently cleaning devices, such as automatic or semi-automatic surface cleaning devices that have at least one surface scrubbing system, do not have an efficient drying system that leaves the floor ready to step on after immediate use since, in addition , do not contemplate systems for draining the fabric or material to be used, so that the drying function would not be fully contemplated by the inventions existing in the state of the art.

Overcoming the drawbacks of the previous section, the invention presents an automatic drying system for wet surfaces, including a wringing system for a mop and / or absorbent fabric that comprises at least three rollers, at least one transmission system and at least one reservoir. of sewage.

This system can be used by being mounted on a cleaning device that includes scrubbing functions, configured as a subsequent stage.

The system starts its operation by activating a driving roller that will be induced to rotate thanks to a motor, which may be electric, and a transmission mechanism.

In the event that the surface drying system is implemented in an autonomous movement device, such as a robot vacuum cleaner, the drive roller will have a rotation speed equal to that of the autonomous cleaning device itself.

Likewise, the driving roller will transmit its rotational movement to at least two additional rollers and, in turn, to the absorbent fabric.

In this way, by transmitting the movement to the driving roller, the movement of the rest of the rollers is achieved, as well as the absorbent fabric, achieving a circulatory movement of this around the rollers. Following this procedure, the absorbent fabric rotates as the drying system progresses, absorbing moisture from the surfaces.

This is done at the same time that the absorbent fabric dries continuously, thanks to the wringing by means of a controlled pressure with the pressure roller.

The liquid extracted from the drain is deposited by gravity inside the wastewater tank.

The wastewater tank, the result of the draining process of the absorbent fabric, can have a filling control system to prevent the tank from overflowing; For this, it has a sensor to control the height of the liquid reached.

In its entirety, the assembly can be joined in the same structure to be able to extract the drying system in a single block.

In this way, the proposed invention incorporates a wringing system after scrubbing, leaving the surface usable immediately after scrubbing, in addition to collecting dirty water in a tank, ensuring that dirt is removed from the treated surface, in this way no dirt remains on the fabric during the scrubbing process.
