The apertures 34 are located between the segments of the aperture 30 and between the segments of the aperture 32, as seen in FIG.
It extends through 4.

Openings 30 and 32 each have a filter tank 38
The bolt 36 is configured to receive a bolt 36 extending from the bolt 36.

A pair of filter tanks 38 are provided on the filter tank cover 24 as shown in the figures.

A filter 40 made of paper is installed in each filter tank 38 as shown in the drawing.

Each of the filter tanks 38 has an inlet 42 midway between its ends.

The bolts 36 extend through each aperture 34 and have deflection knobs 44 threadably provided at their rear ends for retaining the filter tank 38 on the cover 24. There is.

As shown in FIG. 8, the knob 44 has a forward deflection surface that is disposed at an angle of approximately 15° to the rear surface of the cover 24 for purposes described in detail below. Contains 46.

The rear surface of cover 24 includes a pair of flow deflection tabs 48 extending therefrom, which are adjacent to the rear side of apertures 30 and 32 as well as knob 44, as shown in the figures. It is arranged as follows.

Conduit 50 extends from opening 28 to inlet 42 on filter tank 38 .

4 and has a pair of spaced apart tabs 58 and 60 extending outwardly from the front end of the device.

66 designates a pass-through or transparent cover that is removably attached to the rear end of the debris arrester 52 by a clamp 68, as shown in FIG.

Flexible filter valve 70 connects debris arrester 52
5 and which normally closes the conduit 54, as shown in phantom in FIG.

When water is pumped through conduit 22, valve 70
is moved to the position indicated by the solid line in Figure 5 (.

A plurality of spaced communicating lowers 2 extend through the front end of the debris arrester 52 and communicate with an outlet or discharge conduit 56 .

A baffle plate 74 arranged vertically and extending rearward,
As shown in FIGS. 3 and 5, the blocking device 5
2 is provided between each row of connecting lowers 2 so that the internal debris of connecting lowers 2 does not have a sealing or surface covering effect on the connecting lowers 2.

Filter 12 is mounted on cleaner 10, as shown in FIG.

The location of the filter on top of the machine distributes the weight of the filter across the rear drive axle to improve suction of the pool cleaner.

The improved suction action allows the pool cleaner to climb steep slopes and move across pools with seaweed deposits or vinyl or plastic backings.

Also, the location of the filter is such that it prevents the cleaner from hitting or scratching the pool walls or steps while turning as it moves across the bottom of the pool.

Activation of the cleaner 10 causes a pump above the cleaner to draw debris and water from the bottom of the pool via the drain conduit 22 and into the interior of the debris arrester 52 .

Water flowing into the debris arrester deflects a filter valve 70 made of thermoplastic rubber.

When the machine is shut down, the filter valve 70 closes due to the weight of the water on top of the valve flow itself.

Closing of filter valve 70 allows debris in the arrester to be easily removed while the machine is still in the water.

When the machine is in operation, the opening in valve 70 directs leaves and other large debris to the outlet section of the arrester.

Vertical baffles 74 adjacent to the connecting lower 2 serve to prevent leaves and heavy debris from sealing or covering the connecting lower 2.

Water and small debris particles are pumped into conduit 50 via outlet conduit 56 and then into filter 4
0 is pumped into each of the filter tanks 38 which filter out debris particles.

Clean water is drained from tank 38 via drain openings 30 and 32.

Drainage is deflected upwardly by a forward deflection surface 46 and a flow deflection tab 48 on knob 44 .

It is undesirable to drain water downward from the filter.

This is because such flow agitates the dirt on the bottom of the pool into suspension, which defeats the primary purpose of the device.

The water discharged upwards also acts to increase the downward pressure, ie the thrust on the rear axle drive, thereby increasing the suction force of the machine.

As previously mentioned, the leaves and debris are held in the position shown in FIG.

This fact makes it easy to observe the debris arrester filling since the debris is visible through the transparent cover 66.

This observation can be made by simply looking down into the water and keeping an eye on the machine while it is operating.

If the debris arrester appears full, the machine is stopped and the operator must reach into the water and rotate the two cam clamps 62 and 64 to remove the debris. Simply remove the blocking device and move it to the pool side.

The clamp 68 is then loosened so that the interior of the blocking device can be flushed out and replaced on the machine without removing the entire machine from the water.

This action may have to be repeated several times in dirty pools containing large debris molecules such as leaves and pine needles.

With larger debris particles being prevented from entering the main filter, the time interval between cleaning the two cylindrical filter elements 40 is lengthened.

If the main filter 40 needs to be cleaned, the knob 44 can be unscrewed and the tank 38 can be removed so that the filter 40 can be cleaned.

Tank 38 is reinstalled via knob 44.
