• Four screws 90 are provided, each adapted to be received by one of the receiving members 86.
• the vertical restraining walls 84 restrict the movement of the module 22 to prevent it from sliding.
• Internal floats 92 are provided between upper side edges 94 of the module 22 and the sidewalls 28 of the frame 16 in order to fully secure the module within the frame. They also help to impart an upright orientation to the robot 10 when submerged in water.
• Figs. 7 A and 7B illustrate the internal module 22 in more detail. It is a self-contained unit and is attached to the frame 16 by a number of screws. When closed, it is preferably sealed to prevent ingress thereto of water.
• the module 22 comprises an impeller 100 associated with a pump motor 104, a shaft 110 associated with a drive motor 106, a receptacle 102, and a clasp 114. Although a single module is shown, it should be appreciated that there may be several, for example separate modules for each motor, a transmission system, electronic controllers, etc.
• the impeller 100 projects from the top side of the module 22. When driven by the pump motor 104, it creates an upward pressure head which draws water into the robot 10 via the inlets, through the filter screen 11, and out of the robot through the outlet opening 26. Besides imparting the necessary movement of water for filtering, this action also provides suction which tends to bias the robot 10 toward the surface which is being cleaned. This is especially useful when the robot 10 is cleaning a sidewall.
• the drive motor 106 comprises a stator housing 108, in which the motion is produced, and the shaft 110.
• the shaft protrudes from a sidewall of the module 22. It may be located non-concentrically to the main shaft of the motor (i.e., that which is located within the stator housing 108), and rotated by any mechanism, a plethora of which are known per se in the art.
• the shaft 110 is of a generally circular cross-section. However, two sides 112 thereof are planar. This allows it to be received within a correspondingly shaped aperture in the timing belt pulley 48, thereby transmitting foil rotational force thereto without slippage.
• the receptacle 102 is adapted for plugging therein the power cord 24.
• the receptacle is adapted to be waterproof, at least when the power cord is plugged in.
• the clasp 114 is adapted to retain the power cord 24 in position, at least when it is plugged into the receptacle 102.
• the filter screen 11 is installed between the filter bag 13 and the internal frame 16. It is affixed by one screw in each side to a screw hole
• the filter screen 11 is disposed between the internal module 22 and the filter bag 13.
• the internal module 16 comprises several auxiliary outlets 45 provided near the bottom of the sidewalls 28.
• Each auxiliary outlet 45 comprises four openings 47 and a center hole 49 adapted to retain a diaphragm (not shown) on the outside of outer surface of the sidewall.
• the diaphragm is a disc of rubber with a central protrusion adapted to be retained by the center hole 49.
• the auxiliary outlets 45 provide an additional means for water to exit therefrom.
• the diaphragms block water from entering the robot through the auxiliary outlets 45.
• the sidewalls 28 further comprise receiving members 46 which are internally threaded and disposed so that they receive screws adapted to secure the cover 12.
• the internal components of the robot 10 are arranged in such a way so that there is a weight imbalance about an axis of symmetry 96 (seen in Fig. IB) which is parallel to the track 20. (It will be appreciated that the robot 10 moves in the direction of the track 20, and thus of the axis of symmetry 96.) Due to this imbalance, the robot 10, when moving, tends to curve away the side with the imbalance (i.e., if the left side of the robot 10 is heavier, the robot will tend to follow a trajectory which curves right). The imbalance is such that the heavier side of the robot 10 is attached to the float 19.
• the imbalance IB rob0t of the robot can be expressed as follows:
• a counter- weight is provided. This is typically done by increasing the suction of the robot 10 through the inlets.
• the robot will tend to follow a curved trajectory.
• the total weight of the robot was 0.6 kg.
• the heavier side of the robot was 3 times the weight of the lighter side, resulting in the heavier side being 0.45 kg, and the lighter side being 0.15 kg.
• a counter weight was provided by increasing the suction to 1.1 kg.
• the robot 10 may have arrangements facilitating its operation with the imbalance.
• it may have its side panel 14 which is located on the lighter side of the robot 10, modified as shown with respect to panel 14a in Fig.
• the side panel 14a comprises fins 132, constituting a fulcrum, which are made of a high-friction elastomer material, and which may be formed integrally with the side panel 14a.
• Each fin 132 is typically located at an end of the side panel 14a near one of the brushwheels 18, and projects from the side panel 14a so as to form with the side panel, an angle ⁇ which faces in the expected direction of movement of the robot and which does not exceed 90°.
• the side panel 14a may comprise auxiliary fins 133, located adjacent one of the fins 132 and projecting from the side panel at an angle different from that of the fins 132.
• the robot 10 which is designed for moving essentially parallel to its side panels, with one of the brushwheels 18a constituting its front end, may approach a sidewall of a swimming pool with its side panels oriented perpendicular to the sidewall or with its side panels oriented at an angle to the side wall, e.g. along a direction indicated by arrow 130 in Fig. 1OA.
• the first part of the robot to impact the sidewall is a corner thereof, e.g. corner 160 between brushwheel 18a and the side panel 14a and it is desirable to make sure that the robot will pivot around this corner, in a clockwise direction indicated by arrow 145, so as to bring the brushwheel 18a in a position parallel to the sidewall, as shown in Fig.
• the robot 10 Since the robot 10 according to the present invention has a weight imbalance, it only requires the side panel 14 which is on the lighter side thereof to be replaced to have the fin 132. However, it will be appreciated that both side panels 14 may have fins.
• the auxiliary fin 133 is useful for ensuring that the robot 10 pivot in the desired direction as described above when either robot 10 approaches the sidewall at an angle such that the fin 132 will not effect the desired pivoting, or if the sidewall is formed at such an angle that the fin 132 will effect the desired pivoting.
• the robot 10 may comprise another modification in its side panel 14, as illustrated in Fig. 13 with respect to a side panel 14b.
• the side panel 14b comprises a freely rotating roller 136 such as a wheel, whivhwhich may be located near the bottom of the side panel 13b, and which is adapted to rotate in a direction, indicated by arrows 137, which is generally perpendicular to the bottom of the robot 10.
• This modification is directed to improve the robot's behavior associated with its climbing a sidewall of a swimming pool, especially when the robot has an imbalance as described above.
• the roller 136 will allow the robot, which is now lying on its side with its bottom toward the wall, to roll away from the wall, as schematically illustrated in sequence in Figs. 14A through 14C, to finally bring it to the bottom of the pool in an operative position. Since the robot 10 has a weight imbalance, if it falls as described above with reference to Fig. 12, it will usually fall onto its heavier side. Therefore, it may be sufficient to provide the roller 136 only on that side panel 14 which is on the heavier side thereof to be replaced. However, it will be appreciated that, for example, a robot without a weight imbalance, or which may tip to either side, may have modified side panels 14b on both sides thereof.
