    The subject matter disclosed herein discloses a swimming pool cleaning robot adapted for cleaning a surface and / or water of a swimming pool, and capable of utilizing two types of filtration systems, i. an internal filtration system and an external extraction and filtration system. Each of these filter systems has its own advantage over the other and can be selected for cleaning the pool according to various circumstances, such as the type and amount of residues in the water, the type of swimming pool (for example, a normal swimming pool, a biological swimming pool). For example, if there are debris (e.g., leaves, plant parts) in the pool that can at least partially block an internal filter (which is part of the internal filtration system), then the external suction and filtration system can be selected. This can be important for biological swimming pools, for example. However, if simple pool cleaning is required, it may be preferable to use the internal filtration system. This type of filtration system may be more economical, less complicated and simpler in function.
    As shown in FIGS. 1 to 3, there is provided a swimming pool cleaning robot, generally indicated at 10. The robot 10 in Figs. 1-3 is arranged to clean the pool using an internal filtration system, as explained below. The robot 10 includes a housing 20 having a housing bottom 22 and a top surface 24 of the housing with a first cover 21 and a second cover 22 and a drive unit 40 having a pump impeller 44 connected to a pump motor (not shown) is that turns the impeller in operation. The drive unit 40 further includes two motors 42 (shown in FIG. 6) configured to move the robot in the pool by rotating right and left movement belts 12, respectively.
    As another example, the impeller motor and motors 42 may be one and the same engine utilizing a distribution system to simultaneously operate the impeller and motors 42.
    The housing 20 further includes a first filter chamber 26 and a second filter chamber 28 formed therein so that the drive unit 40 is interposed therebetween. As shown in FIG. 2, each of the filter chambers 26 and 28 receives a first filter unit 27 and a second filter unit 29, respectively. The first and second filter units 27 and 29 form part of the internal filtering system and filter the water of the swimming pool which it passes through while being pumped by the impeller 44. The filter units 27 and 29 consist of a rigid frame and can be removed from the robot 10 for cleaning, replacement and when using the external suction and filter system instead of the internal filter system.
    Furthermore, the robot 10 comprises a handle 60 containing two floats 62, which maintain a balanced position when used on the bottom of a swimming pool and a balanced position when cleaning on the waterline.
    The drive unit is sealed in the housing 20 and can be operated by being connected to a power source (not shown) via a power cable 41. The drive unit 40 further includes a main controller (not shown) that can be programmed to control the operation of the robot, and more particularly, the operation of the motor 42. For example, the main controller may be programmed to pass the pool through one of several algorithms.
    The robot 10 further includes moving belts 12 driven by the motor 42, two main brushes 14 and between them an auxiliary brush 15, all of which are connected to the moving belts 12 and can be operated by the motor 42, so that In operation, a pump motor of the drive unit 42 drives the impeller 44 to draw water via the robot 10, and simultaneously rotates the motors 42 to rotate the moving belts 12 and the main brushes 14 connected thereto.
    The housing 10 further includes a pump impeller outlet 30 formed in the top surface of the housing 24, and first and second bottom inlets 32 and 34 formed in the housing bottom 22. The first and second bottom inlets 32 and 34, as shown in FIG. 3, are in fluid communication with the first and second filter chambers 26 and 28 and with the first and second filter units 27 and 29. In the construction of the robot 10 of FIG 1 to 3, in which the internal filtering system is employed, the first and second bottom inlet 32 and 34 are in first fluid communication with the impeller outlet 30 via the first and second filter units 27 and 29, respectively Fluid path 51 (shown in FIG. 2).
    In operation of the robot 10, when the internal filtering system is used, the impeller 44, which is operated by the impeller motor, draws in water and debris from the bottom or sidewall of the pool via the first fluid path, i. via the first and the second water inlet 32 and 34 through the first and the second filter 27 and 29 in the direction of the impeller outlet 30. The clean water is discharged via the Pum-penrad-outlet 30. In addition to allowing cleaning of the pool, this process creates a thrust force that forces the robot 10 toward the surface of the pool. This push force keeps the robot close to the surface of the pool so that the bottom of the pool is cleaned and it moves up and cleans the wall of the pool. This function is generally similar to the function of known electrically powered robots with internal filtration systems, such as the robots disclosed in US 2009/0045110 and US 2010/0306931. Simultaneously with the operation of the impeller 44 by the impeller motor, the motors 42, as disclosed above, rotate the moving belts 12 which rotate the two main brushes 14 and the sub-brush 15. This gives the robot 10 the ability to move and clean the surface of the pool with the brushes.
    In addition to the ability of the robot 10 to clean the swimming pool with its internal filtering system, the robot is able to clean the swimming pool using an external suction and filtering system, as described below with reference to FIG Fig. 4 to 8 will be described.
    To clean the swimming pool with an external suction and filtration system (not shown), which may be the pool filtration system (eg, normal pool filtration systems, biological filtration systems) or any other filtration system, 4, in the first step, as shown in FIG. 4, in the first step, the first and second covers 21 and 23 are pivotally opened to remove the filter units 27 and 29 from their filter chambers 26 and 28, respectively. The connection of the robot 10 to the external exhaust and filter system and its function when connected to this system will be described in detail below.
    The first cover 21 of the upper surface 24 of the housing, as can be seen with reference to FIGS. 5 and 6, includes an additional inlet 72 and an additional outlet 74 disposed on a common opening 70 formed therein. The opening 70 can be opened and closed with a flap 76 which is shown in Figs. 1 and 2 in its closed position and in Figs. 5 and 6 in its open position.
    The additional outlet 74 serves to pump water with debris from an area below the housing bottom 22 to the external suction and filter system. When the water is taken up with debris in the external suction and filter system, it is filtered therein and clean water is returned to the pool.
    To feed the water with residues to the external suction and filter system and pump it into it, the first bottom inlet 32 for a second fluid connection with the additional outlet 74 via a second fluid path 52 (extending from the first Fluid path 51 is different) used. The second fluid path 52 forms part of an external suction and filter fluid path 54 that results when the additional outlet 74 is brought into fluid communication with the external aspirating and filtering system.
    After removing the filter units 27 and 29 from their filter chambers (shown in FIG. 4), the flap 76 is opened and an adapter unit 80 (shown in FIGS. 6 and 7) is inserted into the first filter chamber 26. The adapter unit 80 has an interior portion configured to provide fluid communication between the additional outlet 74 and the bottom inlet 32 to form part of the second fluid path 52. When the second fluid path 52 is made by the adapter unit 80, the first fluid path 51 must be completely shut down. Therefore, in addition to removing the filter units 27 and 29 from their filter chamber, the second bottom inlet 34 must be sealed to prevent ingress of water into the second filter chamber 28. This sealing is accomplished by inserting a sealing member 35 (shown in FIGS. 6 and 8) into the second bottom inlet 34.
    Referring to FIGS. 6 and 7, the adapter unit 80 has a first end 84 and a second end 86 disposed at opposite ends of the inner portion 82. When the adapter unit 80 is mounted in the first filter chamber 26, its first end 84 is in fluid communication with the first bottom inlet 32, and its second end 86 is in fluid communication with the additional outlet 74. That is, the second end 86 of the adapter unit 80 connected via the additional outlet 74 with a hose adapter 90, which establishes fluid communication between the second end 86 and a hose 92. In operation, the tube 92 is connected to the external aspirating and filtering system to draw water and debris to the external aspirating and filtering system via the adapter unit 80 and the first bottom inlet 32. The hose adapter 90 includes a rotating mechanism 91 that is configured to prevent twisting of the hose 92.
    When the external suction and filter system is used, the robot must still be close to the surface of the pool (as in the case of the internal filter system), using a thrust force to accomplish the intended cleaning operation To clean the bottom of the pool and to be able to move up the wall of the pool and clean it. To this end, when the adapter unit 80 is disposed in the first filter chamber and the flap 76 is opened, a third fluid connection is established via a third fluid path 53 formed between the additional inlet 72 and the impeller outlet 30. The third fluid path 53 serves to introduce water from the sides of the robot and expel it via the impeller outlet 30 so as to generate the thrust force by which the robot 10 is pushed toward the surface of the pool. In operation, the impeller motor is operated to rotate the impeller 44, and the motors 12 are operated to rotate the belts 12 which are responsible for the movement of the robot and the rotation of its brushes 14 and 15. By this function of the impeller 44, the water is sucked into the robot via the third fluid path 53. When the motors 42 are operated to move the robot along the surface of the swimming pool, and the impeller motor is used to rotate the impeller 44 and generate the thrust force keeping it close to the surface of the pool, the external pump Suction and Filter 8/21
    fctemidtic pitwiarot AT 13 531 U1 2014-02-15
    System water and residues over the second fluid path and filters them.
    This simultaneous operation produces two oppositely directed fluid streams in the opening 70, i. a fluid flow via the additional outlet 74 to the external aspirating and filtering system and an opposite flow through the additional inlet 72 disposed around the additional outlet 74 into the interior of the robot. It should be noted that when the internal filtration system is used, the flap 76 must be closed to prevent ingress of water through the opening 70 and, if the external extraction and filtering system is used, the flap 70 must be opened in order to allow the second and third fluid connection and thus to establish the second and the third fluid path.
    As explained above, the robot 10 is arranged to clean a swimming pool using an internal or external suction and filtering system. In order to choose which filter system to use, the robot 10 includes means for switching its operation between the internal and external aspirating and filtering systems, and thus between the first fluid path and the second and third fluid paths. To use the external suction and filtration system instead of the internal filtration system, the following steps must be performed: a) The filter units 27 and 29 must be removed from their filter chambers and the second bottom inlet 34 must be sealed, to shut down the first fluid path 51; and b) The adapter unit 80 must be received in the first filter chamber 26 to produce the second and third fluid paths 52 and 53 in place of the first fluid path 51.
    In order to use the internal filter system instead of the external suction and filter system, the following steps must be performed: a) The adapter unit 80 must be removed from the first filter chamber 26 to the second and the third Fluid path 52 and 53 shut down, and the second bottom inlet 34 must be opened; and b) the filter units 27 and 29 must be received in their filter chamber to produce the first fluid path 51.
    In both cases, i. E. When using the internal filtration system or the external exhaust and filter system, the robot's motors and / or their controller may not be aware of which filter system is being used, as in both cases the robot's motors will be responsible for its use Movement and are responsible for the rotation of the impeller, regardless of which filter system is used, continue to work in the same way.
    When the robot 10 is connected to the external suction and filtration system, its ability to pass water through residues without passing the impeller through the first fluid path provides an advantage in that large debris tends to be to get stuck in the impeller and jeopardize its function. Thus, the fact that the second fluid path is not in fluid communication with the impeller prevents this danger. A further advantageous feature of the robot of the presently disclosed subject matter is that the impeller can be operated further and independently using the third fluid path and simultaneously for passing fluid with residues via the second fluid path to the external aspirating and filtering system generates a pushing force by which the robot 10 is pressed to the surface of the swimming pool. This function of the impeller, for example, can ensure that the robot does not detach from the wall of the swimming pool when it moves upward.
    Reference is now made to FIG. 9, which schematically illustrates a receptacle 100 arranged to close the power cord 41 and the hose 92. FIG takes up each other. A plurality of receptacles (holders) 100 may be used to receive the power cable 41 and the hose 92 together. The receptacle 100 includes an opening 105 adapted to allow for imports of the power cable 41 and unimpeded rotation of the cable therein, and a gripping device 110 adapted for releasable attachment to the hose 92. Upon movement of the robot in the pool, the hose 92 does not rotate in the gripper 110 due to the rotation mechanism 91 in the gripper 110 and a firm grip of the gripper 110 about the hose 92.
    It will be readily apparent to those skilled in the art to which the present invention pertains that the above-described embodiments are merely examples of the subject matter disclosed herein and that numerous variations, variations, as well as modifications thereof, are possible. 10/21
