Definitions

  • the present invention relates to a method for conveying washing agents into a tub of a washing machine according to the preamble of the first claim.
  • the present invention also relates to a washing machine equipped with a device for conveying washing agents into a tub according to the preamble of claim 5.
  • washing machines such as laundry washing or washing/drying machines or the like, which are equipped with a rotary drum housed in a tub and containing laundry to be washed.
  • Such machines are connected to a water main pipe delivering clean water which enters the machine through a supply duct; clean water is normally also used for carrying two washing agents, e.g. detergent and softener, into the tub.
  • clean water is normally also used for carrying two washing agents, e.g. detergent and softener, into the tub.
  • the machine is equipped with two separate containers adapted to be flushed by the incoming clean water flow, the latter crossing them and carrying with it the washing agent contained therein towards the tub; such containers are typically separate compartments of a filling drawer.
  • the supply duct connected to the water main is split in two delivery ducts, each afferent to a respective container or drawer compartment and fitted with a valve allowing it to be individually opened or closed, so that two washing agents can be dispensed independently.
  • a third additional compartment operating in the same manner as the other two has been added to the drawer; it has therefore been necessary to ensure that said third compartment is supplied as well by using a third delivery duct which involves an additional cost, especially because it too must be equipped with a dedicated valve.
  • supply devices having two inlets and three outlets known as "cross-jet" devices, have been conceived, like the one described in patent GB 2353540 to AWECO Appliance System GmbH & CO. KG; in these devices, the three outlets can be supplied alternately depending on how the two inlets are being supplied.
  • a known cross-jet device 1 is also shown in the annexed Fig. 1 : said device 1 receives water from the main through supply duct 7 that branches off into two delivery ducts 2, 3, ending at respective inlets consisting of delivery mouths A, B; it should be noted that each delivery duct 2,3 is provided with a dedicated valve or solenoid valve 22, 23, so that it can be opened or closed.
  • Cross-jet device 1 comprises a crossing chamber X to which the two delivery mouths A, B and three drain mouths C, D, E are afferent; the latter are connected to as many drain ducts 4, 5, 6 in fluid communication with the three drawer compartments; two drain mouths C, D are aligned with two delivery mouths A, B in a manner such that the lines connecting each delivery mouth to the respective drain mouth intersect within chamber X; the third drain mouth E is located between the other two, and all mouths A, B, C, D, E substantially lie in the same horizontal plane.
  • Crossing chamber X contains air, and the principle of operation of device 1 is based on the crossing of the water jets emitted by delivery mouths A, B: when a jet of water comes out of either inlet A or inlet B, the jet will cross crossing chamber X in a straight line and reach respective outlet C or D; this condition is shown in Fig. 1 by the solid arrows. On the contrary, when water comes out of both inlets A and B, the two corresponding water jets will cross each other within chamber X, resulting in a jet directed towards the third mouth E; this condition is shown in Fig. 1 by the dashed arrows. There is thus no need to use a third delivery duct with a respective solenoid valve, since the three outlets can be supplied alternately by supplying the first inlet A, the second inlet B or both inlets A and B.
  • a further object of the present invention is to provide a washing machine according to the appended claim 5. Further advantageous aspects or variants are also specified in the appended claims, which are intended as an integral part of the present description.
  • the present invention is based upon the idea of using the circuit for recirculating the wash liquid contained in the tub (which may be either pure water or water mixed with a washing agent, according to the case) also for supplying one of the two inlet mouths of the cross-jet supply device.
  • washing machines are often equipped with recirculation circuits, like the ones described in patents DE 43 37 943 or DE 199 02 911, both in the name of MIELE & CIE GmbH, and US 5,191,669 in the name of WHIRLPOOL CORPORATION .
  • the wash liquid contained in the tub is drawn, possibly filtered and then delivered again into the tub, e.g. by spraying it onto the laundry, without needing any additional clean water supply.
  • Fig. 1 is a schematic view of a cross-jet supply device and a respective hydraulic circuit according to the prior art;
  • Fig. 2 is a schematic view of a cross-jet supply device and a respective hydraulic circuit according to the present invention
  • Fig. 3 shows a first variant of Fig. 2
  • Fig. 4 shows a second variant of Fig. 2;
  • Fig. 5 is a schematic view of a washing machine comprising the device and circuit of Fig. 2.
  • the inherent operation of cross-jet supply device 1 shown in Fig. 1 is per se known and has already been described above, so that it needs no further explanation.
  • FIGs. 2 and 5 there is shown a cross-jet supply device 1 with the respective hydraulic circuit in accordance with the teachings of the present invention.
  • Said Figs. 2 and 5 illustrate a simple and low-cost solution of said circuit through a general diagram (Fig. 2) and a schematic view of the arrangement of said circuit in washing machine 100 (Fig. 5), i.e. a laundry washing or washing/drying machine.
  • cross-jet supply device 1 is arranged immediately on top of washing agent drawer 40, and has three outlets consisting of three drain mouths C, D and E in fluid communication (through drain ducts 4, 5, 6 ) with as many distinct compartments 43, 41, 42 of drawer 40; the first and second inlets consist of the two delivery ducts A and B.
  • Compartments 41, 42, 43 are in turn in fluid communication with tub 101 through a supply hopper 103 (per se known); the washing or washing/drying machine 100 normally also comprises a rotary drum 102 housed in the tub, in which the laundry is placed.
  • Three compartments 41, 42, 43 of drawer 40 can be filled with three distinct washing agents (e.g.
  • washing agents even all of the same type adapted to be dispensed into the tub at different times of the wash cycle (e.g. two detergents, whether the same or different, and a softener or the like).
  • Figs. 2 and 5 also show pump 10, which is in fluid communication with tub 101 through suction duct 11; the outlet of said pump 10 is connected to delivery duct 3 ending in crossing chamber X of device 1, with second mouth B aligned with drain mouth D.
  • pump 10 and suction duct 11 advantageously consist of the recirculation pump and recirculation duct, respectively, of the washing machine.
  • Supply duct 7, intercepted by valve 22, is the second delivery duct 2 ending in crossing chamber X with first mouth A aligned with drain mouth C; third drain mouth E is visible between drain mouths C and D aligned with the respective delivery mouths A and B.
  • the system operates as follows: initially, tub 101 is filled (this normally takes place during a "prewash” or "water supply” step, when the laundry is imbibed): to this end, valve 22 opens and clean water (supplied by supply duct 7 connected to the water main) flows in delivery duct 2 and reaches delivery mouth A; the water jet coming out of delivery mouth A crosses chamber X in a straight line and reaches drain mouth C, which is in fluid communication with the tub through drain duct 4, compartment 43 and hopper 103.
  • washing agents in drawer 43, they will be already swept along by the clean water flow during this initial step.
  • wash liquid which may be either pure water or water mixed with washing agents
  • pump 10 it is conceivable to use pump 10 in order to dispense a washing agent contained in compartment 42 or in compartment 41.
  • compartments 41 and 42 must necessarily be intended for washing agents to be used in operating steps of the machine to be executed after the tub filling step; for instance, compartments 41 and 42 are intended for a detergent and/or a softener, whereas compartment 43 may be used for a dye fixative or a detergent to be dispensed during the prewash step; advantageously, compartment 41 is assigned to detergent and compartment 42 is assigned to softener.
  • the wash liquid recirculation circuit to and from tub 101 also comprises device 1 and drawer 40; during the recirculation step of the machine, the wash liquid taken from the tub flows through both device 1 and drawer 40; more in detail, two types of recirculation are possible: mixed recirculation, where clean water is also used, and unmixed recirculation.
  • valve 22 is open and pump 10 is on: in this case, the flow of wash liquid taken from the tub is added to the flow of clean water supplied from the water main, and then this combined flow reaches the tub through compartment 42; this mode of operation may be used when the quantity of wash liquid in the tub is insufficient for the subsequent wash steps to be carried out by machine 100; the wash liquid recirculation circuit to/from tub 101 includes in this case suction duct 11, pump 10, delivery duct 3, delivery mouth B, chamber X, outlet mouth E, drain duct 5, compartment 42, and hopper 103.
  • valve 22 In unmixed recirculation mode, valve 22 is closed and pump 10 is on: in this case, the flow of wash liquid taken from the tub is wholly re-admitted into the tub (except for any liquid spilled or partialized by any means) through compartment 41; this mode of operation may be used when the quantity of wash liquid in the tub is sufficient for the subsequent wash steps to be carried out by machine 100; the wash liquid recirculation circuit to/from tub 101 includes in this case suction duct 11, pump 10, delivery duct 3, delivery mouth B, chamber X, outlet mouth D, drain duct 6, compartment 41, and hopper 103.
  • Pump 10 may be a normal recirculation pump, per se known, which will not be discussed any further. Incidentally, it should be pointed out that a positive displacement pump will also stop the water flow when it is off, thus acting upon duct 11 just like a closed valve.
  • any one of the three outlets C, D, E can be supplied alternately as a function of the two inlets A, B, one of which is supplied with wash liquid from the tub of the washing machine and the other is supplied with clean water from the main.
  • Pump 10' has two outlets which can be supplied as a function of the direction of rotation of the electric motor of the pump itself; pumps of this type are per se known and have been described, for example, in patent US 6,617,733 in the name of DAEWOO ELECTRONICS CO., LTD.
  • pump 10' is a dynamic impeller-type pump; depending on the direction of rotation of the electric motor that drives the impeller, the wash liquid coming in from suction duct 11 will be alternately delivered into either one of ducts 3 and 13.
  • pump 10' may be replaced with a different pump, e.g. a pump fitted with a flow diverter or a shutter adapted to partialize the output flow in order to direct a portion thereof into duct 3 and the other portion into duct 13.
  • Return duct 13 may also include a drain branch which can be opened by means of a dedicated valve (not shown).
  • washing agent contained in compartment 41 or 42 can be dispensed independently of recirculation, unlike the preceding case, where during the first recirculation step the washing agent contained in compartment 41 or 42 (depending on whether solenoid valve 21 is open or closed) is necessarily dispensed; it follows that, if on the one hand this solution implies the presence of a return duct 13 specifically intended for recirculation, on the other hand it offers more flexibility of use.
  • the different recirculation modes are similar to those discussed above, with the additional option of executing an unmixed recirculation step and a mixed recirculation step without necessarily involving drawer 40 (or any compartment thereof): in unmixed recirculation mode, it will be sufficient to activate pump 10 in a manner such that it directs the wash liquid into duct 13 while keeping valve 22 closed, whereas in mixed recirculation mode it will be sufficient to activate pump 10 in a manner such that it directs the wash liquid into duct 13 while keeping valve 22 open (in this second case, mixing takes place in tub 101).
  • pump 10 is a traditional one (with one inlet and one outlet); at the delivery side of pump 10 there is a flow di verier 14 adapted to convey the wash liquid alternately into return duct 13 or into delivery duct 3: in practice, pump 10 and flow diverter 14 carry out the same functions as pump 10', and may even be integrated into a single casing. In this case as well, the system operation is similar to that described above with reference to Fig.
  • flow diverter 14 can also partialize the wash liquid flow so that device 1 and return duct 13 receive flows which can be adjusted at will by operating diverter 14; such a solution may be advantageous when the jets simultaneously emitted by mouths A and B are not capable of generating a single jet directed towards mouth E (e.g. because the flow rates of the jets coming out of mouths A and B are different, and the resulting jet is not directed towards mouth E), in which case flow diverter 14 also acts as an element for adjusting and calibrating device 1, thus allowing to change the rate of the wash liquid flowing in one of the two inlets of device 1 for the purpose of obtaining an optimal operation of device 1.
  • pump 10 may be (in certain solutions) a pump used for both the recirculation and drain functions (to a drain duct), being provided for that purpose with a flow diverter arranged downstream of the pump itself and adapted to switch the path of the wash liquid taken from the tub towards a drain or towards a recirculation circuit; in other solutions, the pump used for the drain function may alternatively be distinct from the one used for the recirculation function.
  • flow diverter 14 may be a three-way valve.
  • the valves may advantageously consist of solenoid valves, which can be controlled automatically.
  • compartments 41, 42, 43 for the three washing agents may more generally be three separate washing agent containers associated with or incorporated into other devices of the washing machine; for example, they may be integrated into the machine frame, arranged in a fixed position and filled from above, or else they may be containers internally or externally associated with the tub, e.g. arranged on the door that allows access to the tub and drum.
  • the three containers will be supplied by means of device 1 as previously described, being additionally necessary only to ensure that the three drain ducts 4, 5, 6 are afferent to the respective containers in fluid communication with tub 101.
  • cross-jet device 1 on top of drawer 4 is optional, since device 1 may also be installed in a remote position, at a distance from the drawer or containers.
  • four or more containers may of course be used and supplied alternately depending on the water flow carried by duct 3: in the above-described cross-jet device, in fact, the two input flows generate an output flow directed towards that outlet which is not aligned with the two inlets. If the two liquid flows in ducts 2 and 3 are different, the resulting jet may not be directed in the middle, but at a variable angle dependent on the flow rate difference between the two jets, so that it may even supply a fourth outlet (not shown) afferent to a fourth container. This reasoning may be extended to any number of outlets, provided that the flow rate can be adjusted with accuracy.
  • the flow rate may be adjusted by acting upon the pump, e.g. by increasing the revolution speed thereof, if it is a dynamic impeller-type pump, or else through flow diverter 14 as previously described. By adjusting the flow rate it will thus be possible to supply any one of the available outlets.
