During the assembling the use of flexible bands for fixing the interconnecting tubes is also completely eliminated and consequently possible additional causes of water leaks are obviated.
- A further object of this invention is to provide a softening device as related above, by means of which the filling of one or more chambers of the vessel for the regeneration water can be selected by simply opening or closing a venting conduit.
- According to this invention a water softening device for dishwashing machines has been provided, said device comprising: an ionic resin container connected to the interior of the washing tank of the dishwashing machine, respectively to a water inlet via a feeding conduit having an arch shaped portion provided with a first lateral aperture defining an air-break for the water; a salt container connected to the resin container by a solenoid valve; and a vessel for collecting the water to regenerate the resin said vessel comprising at least a first bottom opened chamber connected to the salt container, said chamber being furtherly connected to an upper venting hole characterised in that said water regeneration collecting chamber, said water feeding conduits and the respective passages for direct communication between the vessel and the aforementioned salt and resin containers, are provided in the form of a single unit having a plane configuration in which said vessel extends upwardly from and integral with the salt and resin containers, said water feeding conduit being in communication with the regeneration water chamber means of a second side opening positioned after the arch shaped portion; and at least a second supplementary chamber in said vessel, said second chamber communicating at he bottom with the first chamber and being selectively connectable to a separate air venting duct.

- Figure 1 shows part of a
dishwashing machine 10 comprising awashing tank 11 provided with arotor having nozzles 12, said rotor being connected to apump 13 for feeding the washing water in an usual form. 14 in Fig. 1 indicates as a whole a device for softening water according to this invention, which is partially positioned below and on a side of thewashing tank 11. The softening device is shown in detail in the remaining figures. - As can be seen from Figs. 2, 3, and 4, the softening device comprises a
container 15 for the ionic resin used to soften the water, and acontainer 16 for the salt used to regenerate the ionic resin which is connected to thecontainer 15 by means of a solenoid valve, not shown, provided in aseating 17 on one side of thesalt container 16. - 18 in the figures indicates a vessel for collecting the regeneration water which must be fed to the
salt container 16 to form a certain amount of brine required to regenerate the ionic resin in thecontainer 15. - As shown in the figures, the
vessel 18 and thecontainers - In particular, the
vessel 18 is flat shaped and provided with aconduit 19 for feeding the water, in which theconduit 19 comprises a rising portion 19a connect to the inlet fitting 20, a first arched or arch shaped portion 19b and a second arch shapedportion 19c, concentric and internal to the previous one, which continues with a downwardly directedportion 19d which, via aduct 21 formed in the bottom part of the softening device, communicates with the interior of theionic resin container 15, as shown in Fig. 7. The secondarched portion 19c of the water feeding conduit, on its inner side has anaperture 22 defining, in a manner in itself known, an air-break for the water flow which runs along theconduit 19, before entering theionic resin container 15 and then the tank of the dishwasher machine. - The
flat vessel 18 comprises moreover afirst chamber 23 for the regeneration water, and at least asecond chamber 24 communicating with the first one and which, like the latter, opens at the bottom into the salt container 16 (Figs. 4 and 6) via a set ofopenings 25 in thelower part 23a common to the two chambers of the wall wich divides from the interior of the salt container. - The
first chamber 23 again opens above and is connected to thefeeding conduit 19 by a secondlateral opening 26 provided at the beginning of the downwardly orientedportion 19d, i.e. after thearched portion 19c; thisopening 26 can be properly dimensioned for example providing it in a plate, not shown, which can be inserted in a seat to enable thevessel 18 to be filled at the same time as thetank 11 of the dishwashing machine. - A
slanted baffle 27 is provided between the upper open end of thechamber 23 and the air-break opening 22 of thearched section 19c of the feeding duct to prevent any leaks of water from theopening 22, from entering thechamber 23 by varying or modifying the quantity of water collected in it. - The
chamber 23 is further connected to aside venting chamber 28 by means of anopening 29 which defines the maximum level of water which can be loaded in thechambers venting chamber 28 in turn communicates with the outside by means of anupper opening 30 and respectively communicates with the inside of thetank 11 of the dishwashing machine by means of acircular opening 31 for releasing steam. Between theupper opening 30 and thelower opening 31 of theventing chamber 28,fins 32, slanted in opposite directions are formed to define a steam condenser, integrated with the unitary structural assembly of the softening device. - Unlike the
first chamber 23, thesecond chamber 24 for the resin-regeneration water is closed and communicates by means of anopening 34 with aseparate venting duct 33, positioned behind thevessel 18; aremovable plug member 35 enables theventing duct 33 to be closed or opened respectively so as to prevent or enable respectivelychamber 24 together withchamber 23 to be filled. - As stated previously, communication between the
salt container 16 and theresin container 15 is controlled by a solenoid valve. In particular, as shown in the details of Figures 9 and 10, thesalt container 16 communicates by means ofslots 37 with anintermediate chamber 38 having on the opposite side ahole 39 defining a valve seat normally closed by the solenoid valve; in this way thechamber 38 and therefore thesalt container 16 can communicate with the bottom of theionic resin container 15 via anadditional conduit 40 and ahole 41 in the base wall of thesaid container 15. The latter, in the example given in Figure 7, is moreover provided with anupper outlet 42 which protrudes directly into thewashing chamber 11 and which is closed by aremovable cap 43 havinglateral slots 44. Since the level of the water in thetank 11 of the dishwashing machine must never exceed theoutlet 42 of theionic resin container 15, thecap 43 serves as a protection to prevent the dirty water contained in thetank 11 from entering theionic resin container 15. Unlike the example shown in Fig. 7, where there is a direct outlet for water from theresin container 15 to thetank 11 of the dishwashing machine, the inlet of the water into thetank 11 could be positioned differently and suitably connected by means of a water trap or in some other way to the outlet of theionic resin container 15. - The water softening device of the invention is finally completed with a device for indicating the density of the brine contained in the
salt container 16, in the form of a device integrated with the structure of the softening device. More particularly, as shown in Figs. 8 and 10, inside the salt container 16 asump 45 is formed which communicates with the inside of thecontainer 16 by openings orslots 46 in a separating baffle. Inside thesump 45 there is afloat 47 comprising amagnet 48 which, as a function of the position assumed by thefloat 47, in turn dependent upon the density of the brine, actuates or de-actuates amagnetic switch 49 situated outside thecontainer 16, connected to the electrical control circuit of the dishwashing machine. - The softening device operates as follows: on the assumption that only the
chamber 23 of theflat vessel 18 is to be loaded, theplug 35 is inserted to close theventing duct 33. When water is fed into the dishwashing machine, the water flows along thefeeding conduit 19 and from there, via thelower duct 21, reaches the interior of theionic resin container 15, where the water is to be softened before being fed or entering thewashing tank 11 of the dishwashing machine. At the same time as thetank 11 of the dishwashing machine is loaded, a certain quantity of water passes through the opening 26 of thefeeding conduit 19, filling thechamber 23 for the regeneration water, until it reaches the level indicated by theventing opening 29. This water cannot be released into thebrine container 16 and thus is released into theresin container 15 since the outlet opening 39 into thecontainer 15 is closed by the solenoid valve. Moreover the water in thechamber 23 cannot enter thechamber 24, unless in a minimal part, since it is prevented by the air cushion which remains in the chamber itself. Clearly, should a larger quantity of water be required for regenerating the ionic resin, theplug 35 only has to be removed to enable venting of the air and thus the filling of bothchambers - The water which may fall from the opening 22 in the arched section 19b of the
feeding conduit 19, is deviated by thebaffle 27 towards theventing chamber 28 and from there is introduced into thewashing tank 11 through theopening 31 on the base. - During the operating cycle of the dishwashing machine, when the resin in the
container 15 has to be regenerated, a control signal is given to the above mentioned solenoid valve so that it opens thevalve seat 39 enabling the water in thechamber 23 or bothchambers salt chamber 16 to cause a given quantity of brine to flow towards the resin to be regenerated. At the new washing cycle thechamber 23 or bothchambers - From what has been stated and shown in the enclosed drawings it is therefore clear that the invention deals with a water softening device for dishwashing machines comprising a salt container, an ionic resin container and a vessel for collecting the regeneration water, in the form of a structurally integrated unit in which the various component parts are interconnected by means of internal conduits or passages which avoid the use of additional connecting tubes, with consequent advantages as regards operation and assembling. The flat configuration of the vessel for the regeneration water and its configuration of a single part integral with the salt container and with the ionic resin container, provide a structural unit of extremely small dimensions which can be easily assembled by arranging the
containers vessel 18 on one side of thewashing tank 11; in this way the water softening device can be assembled extremely rapidly and with the advantage that all the operations usually required for assembling the interconnecting houses and of the relative sealing bands are totally eliminated. Furthermore the adoption of chambers open below in the vessel is advantageous in that it allows the automatic elimination of any trace of stagnant water which in time could cause the formation of algae and substances likely to rot with the result of unpleasant smells.
