Definitions

• the present invention reduces these costs considerably, through the fact that the purifier can be purchased as a "do-it-yourself-unit" that can be stalled by the pool owner himself.
• an electrode means refers to the figures 1, 2, 3, 4, 5 and 6.
• Fig. 4,5 show a detail of the electrode means
• Fig. 5 also shows a detail of the electrode means
• Fig. 6 shows a current regulating means
• Fig. 7 shows a variant of the invention
• Fig. 8 shows a further embody ent of the invention.
• the electrode means according to fig. 1-3 has been accomplished to be placed in the pool, either by submerging it into the skimmer or by being hung on to the edge of the pavement of the pool.
• the skimmer is the top outlet of the pool, which is combined with a tin containing a roughing filter consisting of a cup with a grating.
• the electrode means consists of a water-proof box 1 (Fig. 1 and 2) that in its inside has four pillars for the fastening of the lid (3) (Fig. 1, 2 and 3) by means of the screws 6- (Fig. 3).
• a rubber hose 8 is the caulking between 5 and 7.
• the tube 7 has been fastened in the box 1 by means of fitting.
• the electrodes are provided with current through the two-threaded wire 10 which has been squeezed into the wall of the contact box and through a water-proof electric plug 12 and 13, has been drawn across the pavement of the pool 11, and is protected by a rail 14, which has a slot 15 (Fig. 4) or a socket 16 (Fig. 5).
• the one part of the plug (13) has been fastened in the rail 14 by means of ' screws 17 and the other part (12) in the contact box by means of a screw 17 a.
• the rail 14 has been fixed to the pavement of the pool, for.example through screws.
• the lid 3 should be of such a size, larger than the bottom, that it covers the opening of normally existing skimmers.
• the generating mea ⁇ s can be accomplished in the ordinary way, for example according to the German patent writing 2150670.
• the principle is shown in Fig. 6.
• the generating means mentioned has been modified so that the part B, that gives the wanted times for ionization in various current directions, has been exchanged for an integrated circuit with the symbol LM 555.
• the time means 3 should be dimensioned so that the electrode 4 has a plus potential with a longer time interval than the electrode 5, for example the electrode 4 has a plus potential for 25 seconds and the electrode 5 minus for 22 seconds. Moreover, the ampere meter A has been moved to the collectors of the outlet transistors. The centre of the transformator is grounded through a connection D to the ground of the lighting network.
• an indication means for example a light diod 18 in a series with a resistance 19, sensitive to current direction
• a tension indicating means to the electrodes, which is placed next to them, or is placed elsewhere through a mire, because in this way one is able to check that there is no shortcircuit or between the conductors, joined to these.
• the indication means is sensitive to current direction and the time interval is different in the two current directions, it is also possible to check that the two conductors between the current supply and the electrodes have not been exchanged.
• a light diod, or two, indicating one current direction each, one obtains a simple indication means. Via wires the indication means can be placed at an arbitrary place.
• the plug 12 and 13 can be dispensed with if the cable loop 10 is made so long (reaches the skimmer) that it allows the electrodes to be lifted up.
• the lid 3 is to be prolonged to the right (Fig. 2) with at least 150 mm so that the rail 14 can press the lid so much that the electrodes are hanging almost vertically.
• the electrode means When the electrode means is placed on the pool edge it is suitable to protect the electrodes totally or partly, preferably its sides facing the pool. This should be done with a perforated plastic cover which can be fastened in the contact box 1 and/or in the electrodes 4.
• the electrode means should be placed where the water flows, for example by one of the inlets of the pool.
• Fig. 7 shows one way of realizing the invention, where part 12 of the electric plug is fastened on the wall of the skimmer, for example by means of a self-threaded screw and the part 13 on the lid 3.
• the electric plug can naturally be dispensed with, if the cable of the cable loop 10 is made long enough.
• the rail 14 protecting the cable 10 (Fig. 2 and 4) can be dis ⁇ claimedd with, if the cable is placed in a slot or tubes arranged in the wall of the pool of pavement.
• Fig. 8 shows how the electrode means can be placed in the engine house.
• a container 20 is then attached, in which the electrodes 4 and 5 are placed.
• the container 20 has a lid 21, which in the ordinary way is fastened with bolts and caulked with a packing 22.
• the electrodes 4 and 5 are fastened in the lid 21 in the same way as in the bottom of the contact box in the above described way of realization according to Fig. 1-6.
• the lid has a cylinder shaped part 27, which is provided with a lid 24. In this way a space is achieved, which corresponds to the contact box 1 in fig. 1-3, in which a connection of the cable 10 and the turning of the signal lamp 18 is performed.
• the container 20 has a screwed socket 28 for incoming water, for example from the pool, and a socket 29 for outgoing water.
• the container 20 can be provided with a strainer 30 (roughing fiLter) placed in its bottom part.
• the wall of the container should be provided with a window or be made of transparent material so that the electrodes and the roughing filter can be inspected without the removal of the lid 21.
• the container 20 is provided with legs 31 or similar, so that the lid will be in the correct working height above the floor.
• the container is provided with a flange 25 and an outlet 32 enabling the water piercing through when the lid 21 is removed, despite the fact that taps are off before and after the container, can be diverted and will not come on the floor or the engine house.
• the attachment of the container 20 can be in an arbitrary place in the circulation system, but as a rule it is easiest between the taps of the pipes from the pool and the tap (switch) at the sand filter, because in this way no additional taps have to be installed.
• the pipe attachment is so easily performed, by means of the connection parts for attachment of plastic pipes that are now available, that it can be carried out according to the "do-it-yourself principle".
• the power means according to Fig. 6 is connected to the circulation pump so that the electrodes are provided with power when the pump is working.
• silver is added, for example through the fact that one of the electrodes 4 or the rod is made of silver or silver-copper.
• a reed relay can be placed in the contact box opposite the plug part 13 and a perma ent magnet is attached in 13.
• the cable 10 preferably a ribbon cable, is hereby provided with an additional conductor connected to the reed contact and with the help of an operating relay the functions wanted, for example of the just mentioned kind, are performed.
• the invention is not restricted to water purification in pools but can also be utilized by all kinds of water bodies, for example water reservoirs, fish ponds etc.
