152 of the corresponding link 151, with diaphragm fifty eight pressed tightly (by seal plate 155) between ends 152 and 156b (to stop liquid leakage into the control field assembly). With reference once more to FIG. 7, cam tracks 50a have similar shapes, but the two cams 50 are assembled essentially “again-to-again” (one is rotated by 180 levels about the vertical axis in FIG. 7 relative to the opposite), which orients the cam monitor 50a of considered one of them as the mirror picture of cam observe 50a of the other (so that the angular orientation of 1 track 50a about shaft fifty two is displaced relative to the orientation of the other track 50a about shaft 52). Similarly, in the FIG. 10A embodiment, two identical cams 50′ are assembled primarily “again-to-back” on shaft 52, thus orienting cam track 50b of considered one of them as the mirror picture of cam track 50b of the opposite. As shown in FIGS. A seal plate 155 (proven in FIGS. 155a (proven in FIG. 7) of management box portion 14a. A shift link 156 matches within an opening via the center of every seal plate 155. As cam 50 pivots hyperlink 151 upward (or downward), hyperlink 156 at the opposite end of the inflexible shift meeting (comprising hyperlink 151, tube 154, and hyperlink 156) will pivot downward (or AZ Premium Pool Services upward).
Alternatively, the parts are all connected to a single circuit board sixty eight (through which case, board 70 is omitted). In a most well-liked embodiment, the microprocessor is preprogrammed to assert any of two or more sets of control signals to motor 74. For example, the microprocessor can be programmed to assert a primary set of comparatively low current indicators to the motor in the event that the batteries powering the apparatus have a low level (or if the onboard sensors point out that the apparatus is caught against an impediment), and in any other case to assert a second set of relatively excessive current signals to the motor. Stepper motor seventy four and cam gear cluster 55 are additionally mounted within assembled components 14a, 14b, and 14c. Two cams 50 and one cam gear 54 are fixedly mounted on cam shaft 52. Shaft 52 is rotatably mounted to ingredient 14a by cam bearings 51. Thus, cams 50, gear 54, and shaft 52 rotate together as a unit. Gear cluster 55, engaged between motor 74 and cam gear 54, is driven by motor 74 (which is preferably an electronically controlled electric step motor).
The inventors contemplate that the invention is also useful for other applications, e.g., to wash different surfaces submerged in water or in liquids aside from water. Four and 13) and an outlet 10. Outlet 10 is dimensioned for attachment to the lower end of a flexible hose eight (shown only in FIG. 13), and so outlet 10 is typically referred to herein as a “hose connection” 10. Typically, the higher end of hose eight will probably be related to one of many ASP – America’s Swimming Pool Company of Central Texas‘s current suction ports, which in turn is related to a conventional floor unit 8A (shown in FIG. 13) disposed above the water floor. A first embodiment of the invention will be described with reference to FIGS. 1-8 and 11-22. In this embodiment, the invention features a turbine assembly 12 having an inlet 9 (proven in FIGS. The time period “water” will probably be used in a broad sense all through the specification, together with in the claims, to indicate contemporary water, salt water, and any other liquid during which a surface (to be cleaned by the inventive apparatus) is immersed.
In any embodiment of the invention, the programming card could be coded with a pattern of notches at along its edges. Use of such a battery pack allows safer and more handy operation than can be achieved with AZ Pool Service cleaners which have employed a energy cable extending to the submerged apparatus from a energy provide disposed above the water floor. Selection of a bigger inlet size results in slower, more thorough, cleansing than is generally achievable with a smaller turbine inlet. When the notched card is placed into position adjacent the magnetic (or optical or mechanical) switches, the card will (or won’t) actuate mechanical means for controlling the dimensions of a turbine meeting fluid inlet nozzle depending on the absence (or presence) of a notch at the situation of the mechanical means. The larger inlet will also permit for passage of larger debris. In most popular embodiments, the inventive apparatus is powered by an onboard battery pack sealed in a water-tight enclosure. The smaller inlet will give increased turbine pace leading to higher unit velocity and likewise enhance torque for higher wall climbing.
The currents of the “relatively low” current indicators might be chosen to maximize the torque exerted by the motor while minimizing battery consumption, and the currents of the “relatively excessive” current signals can be chosen to maximise the torque exerted by the motor (with no battery consumption minimization constraint). Each of cams 50 defines a cam monitor Aro Pool Builders Innovations Inc 50a (best proven in FIG. 5) having a non-uniform radius relative to shaft 52. In variations on this embodiment, cams 50 are replaced by cams 50′ shown in FIG. 10A or cams such because the cam having camtrack 50A’ shown in FIGS. Thus, the motor could be controlled to eat less power in response to the “relatively low” present alerts than in response to the “comparatively excessive” current signals. 9 and 10. Each of cams 50′ defines at the very least one cam monitor 50b having a non-uniform radius relative to central portion 52a of cam 50′ (cams 50′ are mounted to shaft fifty two by inserting shaft fifty two through portion 52a of every cam 50′). A pair of cam follower hyperlinks 151 (one in all which is shown in FIG. 7A and in FIG. 7B) are offered, every having a cam follower shaft a hundred and fifty which rides in one of many cam tracks 50a or 50b. Or, a pair of cam follower hyperlinks 151′ (one shown in every of FIGS.
