Robot for cleaning swimming pools

Abstract

The present invention relates to a robot for cleaning swimming pools, comprising driving means which can transmit movement to movement means, where the movement means comprise two wheels (2) arranged in line on each side (3, 4) of the robot, the robot having two sides (3, 4), the driving means consisting of a drive unit (5) which is operatively connected to two wheels (2) located on a first side (3) of the robot, comprising at least one drive shaft (6) which allows transmitting the movement originating from the drive unit (5) from said first side (3) to the wheels (2) located on a second side (4).

Description

[0001]This application claims priority of Spanish Patent Application No. P 201131675, filed Oct. 18, 2011, the entire contents of which are hereby incorporated by reference into this application.TECHNICAL FIELD OF THE INVENTION[0002]The present invention relates to a robot for cleaning swimming pools, which can be applied to the aquatic facility maintenance industry, and more specifically in the environment of performing automated maintenance tasks in swimming pool basins.BACKGROUND OF THE INVENTION[0003]There are robots today for automatically performing the tasks of cleaning the surfaces of swimming pool basins, both the bottom and the side walls, for which said robots have the capacity of moving autonomously along the bottom and the walls of the basin, as well as suction and storage means for sucking in and storing the dirt found in the basin, dirt being understood as any type of impurities such as leaves or solid waste which are deposited on the bottom or on the side walls of th...

AI Technical Summary

Benefits of technology

The present invention provides a robot for cleaning swimming pools that has a simple design, is cheaper to manufacture and maintain than existing robots, and has the advantage of being a four-wheel drive and bidirectional robot. This allows for easy assembly, maintenance, and repair. The robot is also more maneuverable and can overcome obstacles more easily. Additionally, the robot has a housing with at least two pins and holes that allow for easy removal of the drive shaft for maintenance or replacement without the need for tools. The shaft and brush can be removed sequentially for interchangeability.

Problems solved by technology

Even though caterpillar tracks allow having a large contact surface for the forward movement of the robot, allowing sufficient driving capacity for forward movement, precisely because of the particularities of these movement means, in addition to having a high maintenance cost, in which the caterpillar tracks sustain high wear and when any of the caterpillar tracks must be replaced due to wear or breakage, replacement is difficult.

Likewise, these devices have a high number of parts and their arrangement is complex from a mechanical point of view, implying a high manufacturing cost.

The drawbacks of these robots include the fact that given the configuration of its driving means and transmission to the movement means, its movement capacity is only in a single direction, according to one and the same direction, being able to rotate about itself to change said forward direction, which implies cleaning down times during said manoeuvres, which taking into account the size of a basin, means a lot of wasted time when cleaning the entire basin.
