Description
- 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.
- 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.
- 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 the basin.
- For autonomous movement, most of these cleaning robots have movement means consisting of caterpillar tracks, usually of rubber or another elastic material for the purpose of preventing damage to the surface of the basin. One example of this type of robots can be found in French patent application no. FR-2946378-A1. 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.
- For the purpose of overcoming the drawbacks of robots with caterpillar tracks, robots for cleaning swimming pools the movement means of which consist of wheels, have recently emerged on the market, such as for example the model described in U.S. design Pat. application No. UD-D599967-S. This robot has a front cleaning roller or brush and a rear propulsion turbine, and consists of four wheels independent from one another and two geared motors, such that the robot has two drive wheels, which in the mentioned example are the front wheels. 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.
- The present invention relates to a robot for cleaning swimming pools which allows having a four-wheel drive and bidirectional robot, all with a simple arrangement, which has a lower cost than currently existing robots. The robot of the invention allows a much simpler assembly and maintenance than the currently existing robots, precisely because of the simplicity in the number of necessary elements as well as their arrangement.
- The robot proposed by the invention comprises driving means which can transmit its movement to movement means comprising two wheels arranged in line on each side of the robot, the robot having two sides.
- Therefore, according to the invention the driving means consist of a single drive unit, which can consist of a geared motor which is operatively connected, with two wheels located on a first side of the robot, being able to transmit a driving force which is converted into movement. The robot comprises at least one drive shaft which allows transmitting the movement originating from the drive unit from said first side to the wheels located on a second side.
- The robot of the invention thus has the particularity that it can be considered a 4×4 robot, with four-wheel drive, which allows the robot to move in any direction, i.e., it can go forwards or backwards indistinctly. This represents a huge advantage with respect to the currently existing robots, given that the working environment is under water and it must have enough driving capacity so as to climb up the side walls of the basin. Precisely because of the high manoeuvrability of the robot, and more specifically because of its driving capacity in both directions, the robot does not involve any cleaning down time during its operation, in addition to the robot being able to overcome obstacles more easily as a result of the four-wheel drive with a single traction motor.
- Currently, the only robots allowing 4×4 drive are caterpillar track robots, with the aforementioned drawbacks. However, the robot of the invention allows reducing the number of necessary components, and therefore the space, which in turn facilitates its maintenance and allows reducing manufacturing, maintenance and repair costs with respect to the currently existing robots, all these determining factors being especially relevant given the robot work place conditions, requiring complete water-tightness. The invention thus allows reducing the total cost of the device by reducing the geared motors from two to one, with all this implies in terms of reducing components and risk when the device works under water.
- Based on the foregoing, solutions of another type do not provide the effects achieved with the invention. In this sense, it is not possible to achieve four-wheel drive by means of a fixed shaft joining the rear and front wheels due to the lack of available space, this being the reason current robots incorporate two geared motors.
- The possibility of the robot comprising at least one cleaning roller which is located around a drive shaft is contemplated; said drive shaft is thus used to be incorporated into a cleaning brush which, though optional, is very useful.
- Likewise, the drive shaft being arranged in its operating position by means of housing at least two pins in at least two holes is also contemplated, the pins being able to be located in the drive shaft and the holes in a casing which the robot comprises robot, or the other way round, which allows the drive shaft to be unlocked sequentially, first from one hole and then from another, and thus be easily removed by the user for changing the cleaning roller, without the need for a technical operator to intervene. Said pins being retractable is likewise contemplated.
- The fact that the drive shaft can be removed by the user him/herself for maintenance or replacement for allowing the interchangeability both of the shaft and of the roller is a huge advantage given that current robots require said change to be done by technical services, although in recent models the cleaning rollers can be removed by the user him/herself since they are attached to the casing by means of screws. Nevertheless, the robot of the invention has the advantage that it does not require screws for locking the drive shaft in its operating position, on it can be removed to change the rollers for maintenance or replacement with a simple key, or even with a pen or the like, sequentially pressing on the pins to unlock them.
- The shaft and the brush can thus be removed without the need for tools such as screwdrivers, etc.
