Abstract
Description
- The present invention relates to a dishwashing machine with pulsed washing water spray jets, which is capable of enabling energy usage in general to be reduced drastically.
- A dishwashing machine of the above cited kind is known from US-A-5 525 161, in which the rotating spray arms are supplied by a circulation pump so as to issue, towards the dishes to be washed, respective pulsed water spray jets, ie. with an alternating sequence of periods and pauses in which the pressure of the water supplying said rotating spray arms is at its highest and its lowest value, respectively. In a preferred manner, during the above cited pauses the rotating spray arms issue low-pressure water spray jets so as to keep up an adequate operating effectiveness of the machine and lower the overall water-generated noise thereof.
- However, to the purpose of supporting the various washload items, dishwashing machines generally comprise an upper rack and a lower rack, below which there is arranged an associated rotating spray arm with main nozzles adapted to issue washing water spray jets directed upwards. In order to ensure a more thorough washing action, at least one of said rotating spray arms also comprises auxiliary nozzles adapted to issue water spray jets that are directed downwards. This is normally applied to the upper rotating spray arm, in view of ensuring a more accurate and thorough washing effect on the washload items arranged in the lower rack. However, also the lower rotating spray arm may (alternatively or additionally) be adapted to issue auxiliary water spray jets that are directed downwards, for instance in view of bringing about a washing action aimed at automatically cleaning the filtering means provided on the bottom of the washing vessel of the machine.
- Anyway, during the above cited pauses, the auxiliary water spray jets turn out to be substantially ineffective and practically constitute respective water losses, or leakages, that further reduce the pressure of the main water spray jets. As a result, even these main water spray jets lose much of their efficiency during said low-pressure operating pauses, under resulting reduction in the overall performance of the machine.
- It is a main purpose of the present invention to provide a dishwashing machine with main and auxiliary pulsed water spray jets, the effectiveness of which is really adequate and optimal under all operating conditions.
- Furthermore, it is a purpose of the present invention to provide a dishwashing machine of the above cited kind, which is simple in its construction and automatic in its operation.
- According to the present invention, these aims are reached in a dishwashing machine with pulsed water spray jets embodying the features as recited in the appended claims.
- Anyway, characteristics and advantages of the present invention will become more readily apparent from the description that is given below by way of non-limiting example with reference to the accompanying drawings, in which:
- Figures 1 and 2 are schematical, partial views of a dishwashing machine according to the present invention, in respective operating conditions thereof; and
- Figures 3 and 4 are schematical, longitudinal-section views of an enlarged detail of the dishwashing machine illustrated in Figures 1 and 2, respectively.
- With reference to the Figures, the dishwashing machine comprises mainly a
washing vessel 5, in which there are accommodated, for supporting the washload items, at least anupper rack 6 and preferably at least alower rack 7. - Said
racks spray arms 8 and 9 arranged therebelow. These rotating spray arms are provided with a plurality ofmain spray nozzles 10 adapted to eject respective washing water spray jets towards the respective racks, as this will be described in greater detail further on. - In a per sé known manner, at least one of these rotating
spray arms 8, 9 also comprises at least anauxiliary nozzle 12 adapted to eject a respective water spray jet, as this will be better explained further on. - In the example being described here, a plurality of
auxiliary nozzles 12 are provided in the upper rotatingspray arm 8 to the purpose of ejecting water spray jets that are directed against thelower rack 7 arranged therebelow. - Either alternatively or additionally thereto, one or more
auxiliary nozzles 12 may be provided also in the lower rotating spray arm 9 to the purpose of ejecting water spray jets which may for instance be directed towards the filtering means 11 of the machine, so as to clean them automatically. Such a particular alternative embodiment, which is not shown in the Figures owing to reasons of greater simplicity, is known for instance from US-A-4 972 861. - In all cases, the rotating
spray arms 8, 9 are supplied with water which is delivered under pressure by acirculation pump 13, which is adapted to be operated in the manner as substantially described in the afore cited publication US-A-5 525 161 so as to ensure that the pressure of the water supplying the rotatingspray arms 8, 9 is variable between a highest value and a lowest value during an alternating sequence of operating periods and pauses, respectively. - According to a feature of the present invention, each rotating spray arm that is so provided with
main nozzles 10 and auxiliary nozzles 12 (ie. the rotatingspray arm 8 in the example described here) comprises control means adapted to substantially shut off theauxiliary nozzles 12 during said operating pauses, ie. when the same rotating spray arm is supplied, in correspondence of aninlet port 16 thereof connected to thepump 13, with water having the afore cited lowest pressure value. - In a preferred manner, the control means are adapted to be operated hydraulically in an automatic manner and, to such a purpose, a
partition wall 17 may be provided so as to substantially divide the interior of the rotatingspray arm 8 into twodistinct chambers - The
chamber 18 communicates normally with theinlet port 16 and themain nozzles 10, whereas thechamber 19 communicates normally with theauxiliary nozzles 12 only. - Furthermore, the two
chambers spray arm 8 are adapted to communicate with each other through at least apassage 20 that is normally shut by avalve arrangement 21. The latter comprises substantially ashutter 14 that is loaded by acompression spring 15, or the like, which keeps it normally in its position in which it shuts thepassage 20, as this is shown in Figure 3. - The
spring 15 is so sized as to make it possible for the pushing force thereof to be overcome when, during the afore cited operating periods, the rotatingspray arm 8 receives, at theinlet port 16 thereof, water at its highest pressure value, which therefore is capable of acting with an adequately great pressure on saidshutter 14. As a result, thesame shutter 14 is thereby caused to switch over to a position in which it opens the passage 20 (Figure 4), through which saidchambers inlet port 16 of the rotatingspray arm 8 is then delivered to both themain nozzles 10 and theauxiliary nozzles 12, which are in this way to issue respective water spray jets at an adequate pressure (Figure 2). - On the contrary, during the afore cited operating pauses, ie. when the rotating
spray arm 8 receives water at its lowest pressure value at theinlet port 16 thereof, thevalve arrangement 21 substantially shuts off thepassage 20 and, as a result, also theauxiliary nozzles 12, as this has already been described above. As a consequence, although the water delivered to theinlet port 16 of the rotatingspray arm 8 is at its lowest pressure value, it anyway supplies themain nozzles 19 only, which are in this way able to anyway eject respective water spray jets with a pressure that is sufficient to enable them to perform a substantial mechanical cleaning action on the washload items arranged in the upper rack 6 (Figure 1). - In other words, during said operating pauses, the lower pressure of the water at the
inlet port 16 of the rotatingspray arm 8 is substantially compensated for by the smaller overall passage or flow-through cross-section area of the nozzles that are to be supplied by the same water, ie. themain nozzles 10 only. - The simplicity in the construction and operation of the
valve arrangement 21 is at this point fully apparent. - It will be appreciated that the afore described dishwashing machine may be the subject of a number of modifications without departing from the scope of the present invention.
- For instance, it may prove advantageous for the
valve arrangement 21 to be adapted so that, during said operating pauses, it actually shuts off themain nozzles 10, instead of theauxiliary nozzles 12, for example in view of ensuring a more thorough cleaning of the washload items arranged on thelower rack 7 only. Anyone skilled in the art will in this case readily appreciate that, to this purpose, all it takes is to invert the position of theinlet port 16 and thevalve arrangement 21 with respect to thechambers spray arm 8. - Furthermore, both the
main nozzles 10 and theauxiliary nozzles 12 may be provided on the same side of the rotatingspray arm 8, so as to cause them to eject respective water spray jets that are in all cases directed against theupper rack 6, for instance. In this case, anyone skilled in the art is able to readily understand that, with a simple modification of the structure of thepartition wall 17, it will be possible to arrange things so as to have the washload items arranged on therack 6 normally showered by all of thenozzles nozzles 10 only or thenozzles 12 only during said operating pauses. - It should also be noticed that the present invention may be advantageously applied also to a dishwashing machine in which the rotating
spray arms 8, 9 are supplied alternately, as described for instance in EP-B-0 237 994.
