Definitions
- the present invention relates to a hydraulic system for a laundry washing machine detergent dispenser.
- a standard laundry washing machine comprises a detergent dispenser having a tank with a number of compartments connected at the bottom to the wash tub housing the rotating laundry drum.
- the detergent dispenser also comprises a hydraulic system for feeding a stream of water downwards into each compartment to gradually dilute and flush the detergent/softener from the compartment into the wash tub.
- the tank normally requires three separate streams of water fed selectively into three different compartments, so the hydraulic system comprises three separate feed pipes terminating inside the tank; and, to regulate water flow along the three feed pipes independently, three solenoid valves were formerly used, each located upstream from a respective feed pipe.
- Solenoid valves are fairly expensive, so, to reduce the cost of the hydraulic system, it has been proposed to use two delivery pipes, each fitted with a respective solenoid valve; and a cross mixer interposed between the two delivery pipes and the three feed pipes, and which, when fed with respective incoming streams of water from both the delivery pipes, directs an outgoing stream of water, generated by intersection of the two incoming streams, into a central feed pipe.
- the outgoing streams of water from the two delivery pipes intersect at the cross mixer, so, when both delivery pipes feed respective streams of water into the cross mixer, the two incoming streams of water intersect to form an outgoing stream of water, which is directed into a central feed pipe.
- Number 1 in Figure 1 indicates as a whole a laundry washing machine detergent dispenser.
- Detergent dispenser 1 comprises a tank 2 having three compartments 3 with holes at the bottom for connection to the wash tub housing the rotating laundry drum. More specifically, two compartments 3 for a measure of detergent or softener are arranged side by side at the front, and the third compartment 3 is located at the rear.
- Detergent dispenser 1 also comprises a hydraulic system 4 for feeding a stream of water downwards into each compartment 3.
- the two front compartments 3 are supplied with water by hydraulic system 4 to gradually dilute and flush the detergent/softener from front compartments 3 into the wash tub, while the water supplied by hydraulic system 4 to rear compartment 3 flows directly into the wash tub for rinsing.
- the hydraulic system comprises three separate feed pipes 5 terminating inside tank 2 at respective compartments 3. More specifically, one feed pipe 5 supplying water to rear compartment 3 is located centrally, and the other two feed pipes 5 supplying water to front compartments 3 are located on opposite sides of the central feed pipe 5.
- the three feed pipes 5 are supplied with water by two delivery pipes 6 via a cross mixer 7 interposed between the two delivery pipes 6 and the three feed pipes 5.
- the two delivery pipes 6 intersect at a 90° angle
- the two lateral feed pipes 5 form extensions of the two delivery pipes 6 (and therefore also form a 90° angle)
- the central feed pipe 5 is located between the two lateral feed pipes 5.
- an inlet 8 of each lateral feed pipe 5 is located facing and parallel to an outlet 9 of a respective delivery pipe 6, and an inlet 8 of the central feed pipe 5 is located opposite outlets 9 of the two delivery pipes 6, and forms a 45° angle with outlet 9 of each delivery pipe 6.
- Cross mixer 7 comprises a closed central chamber 10 (i.e. completely isolated from the outside), into which outlets 9 of the two delivery pipes 6 and inlets 8 of the three feed pipes 5 debouche.
- chamber 10 is closed, i.e. completely isolated from the outside, and is therefore bounded by lateral, top, and bottom walls 11.
- the fact that chamber 10 is closed is important, in that intersection of the two streams of water from the two delivery pipes 6 produces a centrally-directed main stream that tends to swell vertically.
- Chamber 10 being closed, however, the top and bottom walls 11 of chamber 10 retain and direct the top- and bottommost portions of the main stream towards inlet 8 of central feed pipe 5.
- Each delivery pipe 6 is regulated by a respective solenoid valve 12 located upstream from delivery pipe 6, and which can be set to a closed setting cutting off water supply to delivery pipe 6, and an open setting permitting water supply to delivery pipe 6.
- central feed pipe 5 is "bulb-shaped" : from inlet 8 facing cross mixer 7, the cross section area starts out at a first minimum value, increases gradually to a maximum value, and finally decreases gradually to a second minimum value smaller than the first.
- the ratio between the first and second minimum value of the cross section area of central feed pipe 5 normally ranges between 1.5 and 2.5, and preferably between 1.9 and 2.1; the ratio between the maximum value and the first minimum value normally ranges between 1.3 and 2.1, and preferably between 1.6 and 1.8; and the ratio between the maximum value and the second minimum value normally ranges between 2.5 and 4, and preferably between 3.1 and 3.5.
- the area of inlet 8 of central feed pipe 5 is 2 to 4 times the area of inlet 8 of each lateral feed pipe 5.
- the cross section area of each lateral feed pipe 5 has a minimum value at inlet 8 facing cross mixer 7, and increases gradually from inlet 8 to a maximum value; the ratio between the maximum and minimum value of the cross section area of each lateral feed pipe 5 normally ranges between 1.2 and 2, and preferably between 1.5 and 1.7; and the ratio between the maximum value of the cross section area of each lateral feed pipe 5 and the cross section area of outlet 9, facing cross mixer 7, of each delivery pipe 6 normally ranges between 1 and 1.6, and preferably between 1.2 and 1.4.
- each delivery pipe 6 decreases gradually to a minimum value at outlet 9 facing cross mixer 7, so that the ratio between the cross section area of outlet 9, facing cross mixer 7, of each delivery pipe 6 and the cross section area of inlet 8 of each lateral feed pipe 5 normally ranges between 1 and 1.6, and preferably between 1.2 and 1.4.
- edges separating inlet 8 of central feed pipe 5 from inlets 8 of lateral feed pipes 5 are preferably rounded.
- central feed pipe 5 at cross mixer 7 provides for maximizing inflow into central feed pipe 5 of the main stream of water produced by the two intersecting streams from the two delivery pipes 6.
- Outlets 9 of the two delivery pipes 6 have a relatively small cross section with respect to feed pipes 5, so that water flows out of outlets 9 of the two delivery pipes 6 at relatively high speed and therefore with greater direction to reduce dispersion.
- respective air break spaces 13 are located along feed pipes 5, downstream from cross mixer 7, and are each defined by a portion of the pipe having no bottom wall. Air break spaces 13 are provided to comply with international regulations governing the manufacture of laundry washing machines and requiring interruption of the continuity of mains water supply pipes, and act as hydraulic non-return valves to prevent contaminated (e.g. detergent-containing) or dirty water from flowing back from tank 2 to the mains via hydraulic system 4, in the event of a malfunction.
- contaminated e.g. detergent-containing
- the air break spaces 13 of the two lateral feed pipes 5 also provide for cutting off any dispersion accidentally flowing into the two lateral feed pipes 5 as the main stream, produced by intersection of the two streams from the two delivery pipes 6, is formed in cross mixer 7.
- the flow and speed, in fact, of any dispersion accidentally flowing into the two lateral feed pipes 5 are so low as to prevent it from getting past air break spaces 13, thus ensuring against any undesired flow from lateral feed pipes 5 to front compartments 3.
- each feed pipe 5 has a bulge, which extends both upwards and laterally, and, at the top, preferably has a semicircular cross section with its axis of symmetry parallel to feed pipe 5.
- feed pipe 5 comprises, at air break space 13, an inlet 14 (into which water flows from air break space 13) located lower down and larger vertically than an outlet 15 (from which water flows into air break space 13).
- Central feed pipe 5 terminates at air break space 13, this being located over rear compartment 3 supplied by central feed pipe 5.

Abstract
Description
- The present invention relates to a hydraulic system for a laundry washing machine detergent dispenser.
- A standard laundry washing machine comprises a detergent dispenser having a tank with a number of compartments connected at the bottom to the wash tub housing the rotating laundry drum. The detergent dispenser also comprises a hydraulic system for feeding a stream of water downwards into each compartment to gradually dilute and flush the detergent/softener from the compartment into the wash tub.
- In a modern washing machine, the tank normally requires three separate streams of water fed selectively into three different compartments, so the hydraulic system comprises three separate feed pipes terminating inside the tank; and, to regulate water flow along the three feed pipes independently, three solenoid valves were formerly used, each located upstream from a respective feed pipe.
- Solenoid valves are fairly expensive, so, to reduce the cost of the hydraulic system, it has been proposed to use two delivery pipes, each fitted with a respective solenoid valve; and a cross mixer interposed between the two delivery pipes and the three feed pipes, and which, when fed with respective incoming streams of water from both the delivery pipes, directs an outgoing stream of water, generated by intersection of the two incoming streams, into a central feed pipe. In other words, the outgoing streams of water from the two delivery pipes intersect at the cross mixer, so, when both delivery pipes feed respective streams of water into the cross mixer, the two incoming streams of water intersect to form an outgoing stream of water, which is directed into a central feed pipe.
- International regulations governing the manufacture of laundry washing machines demand an air break space to interrupt the continuity of a mains water supply pipe, and which acts as a hydraulic non-return valve to prevent contaminated (e.g. detergent-containing) or dirty water from flowing back along the pipe and mixing with drinking water in the mains in the event of a malfunction. In currently marketed laundry washing machines, the air break space is formed at the cross mixer, which is therefore open at the bottom, i.e. has no bottom boundary wall.
- Currently used hydraulic systems of the type described above work fairly well when actual performance of the two solenoid valves regulating the two delivery pipes is the same, i.e. when water flow along the two delivery pipes is substantially the same. Such an ideal condition, however, is fairly rare, on account of manufacturing tolerances, which often result in even substantial differences in performance of the two solenoid valves. As a result, in currently used hydraulic systems, actual water flow along the central feed pipe is often much less than expected; and the desired water flow along the central feed pipe is also accompanied by undesired, harmful dispersion from the lateral feed pipes. Finally, currently used hydraulic systems comprise a large number of mechanically and hydraulically connected component parts, which therefore make them expensive and complicated to assemble.
- It is an object of the present invention to provide a hydraulic system for a laundry washing machine detergent dispenser, designed to eliminate the aforementioned drawbacks, and which, in particular, is cheap and easy to implement.
- According to the present invention, there is provided a hydraulic system for a laundry washing machine detergent dispenser, as claimed in the accompanying Claims.
- A non-limiting embodiment of the present invention will be described by way of example with reference to the accompanying drawings, in which:
-
Figure 1 shows a schematic view in perspective of a detergent dispenser hydraulic system; -
Figure 2 shows a schematic plan view of theFigure 1 hydraulic system; -
Figure 3 shows a section of a cross mixer of theFigure 1 hydraulic system; -
Figure 4 shows a section along line IV-IV of theFigure 2 hydraulic system. - Number 1 in
Figure 1 indicates as a whole a laundry washing machine detergent dispenser. Detergent dispenser 1 comprises atank 2 having threecompartments 3 with holes at the bottom for connection to the wash tub housing the rotating laundry drum. More specifically, twocompartments 3 for a measure of detergent or softener are arranged side by side at the front, and thethird compartment 3 is located at the rear. - Detergent dispenser 1 also comprises a
hydraulic system 4 for feeding a stream of water downwards into eachcompartment 3. The twofront compartments 3 are supplied with water byhydraulic system 4 to gradually dilute and flush the detergent/softener fromfront compartments 3 into the wash tub, while the water supplied byhydraulic system 4 torear compartment 3 flows directly into the wash tub for rinsing. - As shown in
Figure 2 , to feed three separate streams of water into the three different compartments, the hydraulic system comprises threeseparate feed pipes 5 terminating insidetank 2 atrespective compartments 3. More specifically, onefeed pipe 5 supplying water torear compartment 3 is located centrally, and the other twofeed pipes 5 supplying water tofront compartments 3 are located on opposite sides of thecentral feed pipe 5. - The three
feed pipes 5 are supplied with water by twodelivery pipes 6 via across mixer 7 interposed between the twodelivery pipes 6 and the threefeed pipes 5. As shown more clearly inFigure 3 , incross mixer 7, the twodelivery pipes 6 intersect at a 90° angle, the twolateral feed pipes 5 form extensions of the two delivery pipes 6 (and therefore also form a 90° angle), and thecentral feed pipe 5 is located between the twolateral feed pipes 5. In other words, aninlet 8 of eachlateral feed pipe 5 is located facing and parallel to anoutlet 9 of arespective delivery pipe 6, and aninlet 8 of thecentral feed pipe 5 is located oppositeoutlets 9 of the twodelivery pipes 6, and forms a 45° angle withoutlet 9 of eachdelivery pipe 6. -
Cross mixer 7 comprises a closed central chamber 10 (i.e. completely isolated from the outside), into whichoutlets 9 of the twodelivery pipes 6 andinlets 8 of the threefeed pipes 5 debouche. As stated,chamber 10 is closed, i.e. completely isolated from the outside, and is therefore bounded by lateral, top, andbottom walls 11. The fact thatchamber 10 is closed is important, in that intersection of the two streams of water from the twodelivery pipes 6 produces a centrally-directed main stream that tends to swell vertically.Chamber 10 being closed, however, the top andbottom walls 11 ofchamber 10 retain and direct the top- and bottommost portions of the main stream towardsinlet 8 ofcentral feed pipe 5. - Each
delivery pipe 6 is regulated by arespective solenoid valve 12 located upstream fromdelivery pipe 6, and which can be set to a closed setting cutting off water supply todelivery pipe 6, and an open setting permitting water supply todelivery pipe 6. - In actual use, when only one
delivery pipe 6 is supplied with water, water flows straight throughcross mixer 7 into the correspondinglateral feed pipe 5 only; conversely, when bothdelivery pipes 6 are supplied with water, the respective streams of water intersect to form a main stream, which flows solely intocentral feed pipe 5. - As shown in
Figure 3 , atcross mixer 7,central feed pipe 5 is "bulb-shaped" : frominlet 8 facingcross mixer 7, the cross section area starts out at a first minimum value, increases gradually to a maximum value, and finally decreases gradually to a second minimum value smaller than the first. The ratio between the first and second minimum value of the cross section area ofcentral feed pipe 5 normally ranges between 1.5 and 2.5, and preferably between 1.9 and 2.1; the ratio between the maximum value and the first minimum value normally ranges between 1.3 and 2.1, and preferably between 1.6 and 1.8; and the ratio between the maximum value and the second minimum value normally ranges between 2.5 and 4, and preferably between 3.1 and 3.5. - At
cross mixer 7, the area ofinlet 8 ofcentral feed pipe 5 is 2 to 4 times the area ofinlet 8 of eachlateral feed pipe 5. - The cross section area of each
lateral feed pipe 5 has a minimum value atinlet 8 facingcross mixer 7, and increases gradually frominlet 8 to a maximum value; the ratio between the maximum and minimum value of the cross section area of eachlateral feed pipe 5 normally ranges between 1.2 and 2, and preferably between 1.5 and 1.7; and the ratio between the maximum value of the cross section area of eachlateral feed pipe 5 and the cross section area ofoutlet 9, facingcross mixer 7, of eachdelivery pipe 6 normally ranges between 1 and 1.6, and preferably between 1.2 and 1.4. - The cross section area of each
delivery pipe 6 decreases gradually to a minimum value atoutlet 9 facingcross mixer 7, so that the ratio between the cross section area ofoutlet 9, facingcross mixer 7, of eachdelivery pipe 6 and the cross section area ofinlet 8 of eachlateral feed pipe 5 normally ranges between 1 and 1.6, and preferably between 1.2 and 1.4. - The
edges separating inlet 8 ofcentral feed pipe 5 frominlets 8 oflateral feed pipes 5 are preferably rounded. - The particular shape and size of
central feed pipe 5 atcross mixer 7 provides for maximizing inflow intocentral feed pipe 5 of the main stream of water produced by the two intersecting streams from the twodelivery pipes 6. -
Outlets 9 of the twodelivery pipes 6 have a relatively small cross section with respect tofeed pipes 5, so that water flows out ofoutlets 9 of the twodelivery pipes 6 at relatively high speed and therefore with greater direction to reduce dispersion. - As shown in
Figure 2 , respectiveair break spaces 13 are located alongfeed pipes 5, downstream fromcross mixer 7, and are each defined by a portion of the pipe having no bottom wall.Air break spaces 13 are provided to comply with international regulations governing the manufacture of laundry washing machines and requiring interruption of the continuity of mains water supply pipes, and act as hydraulic non-return valves to prevent contaminated (e.g. detergent-containing) or dirty water from flowing back fromtank 2 to the mains viahydraulic system 4, in the event of a malfunction. - The
air break spaces 13 of the twolateral feed pipes 5 also provide for cutting off any dispersion accidentally flowing into the twolateral feed pipes 5 as the main stream, produced by intersection of the two streams from the twodelivery pipes 6, is formed incross mixer 7. The flow and speed, in fact, of any dispersion accidentally flowing into the twolateral feed pipes 5 are so low as to prevent it from getting pastair break spaces 13, thus ensuring against any undesired flow fromlateral feed pipes 5 tofront compartments 3. - In the preferred embodiment in
Figure 4 , atair break space 13, eachfeed pipe 5 has a bulge, which extends both upwards and laterally, and, at the top, preferably has a semicircular cross section with its axis of symmetry parallel to feedpipe 5. To allow for the effect of gravity on the water flowing throughair break space 13,feed pipe 5 comprises, atair break space 13, an inlet 14 (into which water flows from air break space 13) located lower down and larger vertically than an outlet 15 (from which water flows into air break space 13). -
Central feed pipe 5 terminates atair break space 13, this being located overrear compartment 3 supplied bycentral feed pipe 5. In other words,air break space 13 ofcentral feed pipe 5 constitutes both an interruption in the continuity of the pipe, and an outlet intorear compartment 3. - Downstream from
air break space 13, eachlateral feed pipe 5 preferably has a slopingportion 16, which slopes downwards and preferably has an S-shaped vertical section. The water flowing along eachlateral feed pipe 5 undergoes a considerable loss in pressure as it flows through respectiveair break space 13, and each slopingportion 16 provides, downstream fromair break space 13, for increasing the pressure of the water flowing alongfeed pipe 5, so as to at least partly compensate for the pressure loss caused byair break space 13. - As shown in
Figure 2 , eachlateral feed pipe 5 comprises anend portion 17 located over a respectivefront compartment 3 oftank 2 and having a number of throughoutlet holes 18 underneath. In a preferred embodiment, eachend portion 17 is curved and forms at least one "U", andoutlet holes 18 are located asymmetrically on the outer side of the curve to reduce the swirl produced insidefeed pipe 5 byoutlet holes 18, and so reduce load losses insidefeed pipe 5, and air intake intofeed pipe 5 throughoutlet holes 18. A given total outflow fromoutlet holes 18 is therefore achieved with a lower feed pressure todelivery pipes 6, and the noise level is also greatly reduced. - In a preferred embodiment,
outlet holes 18 are also shaped to reduce load losses infeed pipe 5, and air intake intofeed pipe 5 throughoutlet holes 18. More specifically, eachoutlet hole 18 is crescent-shaped with its concavity facing in the water flow direction alongfeed pipe 5. In theFigure 2 embodiment, the rear edge of eachoutlet hole 18 is circular (i.e. defined by an arc of a circle), whereas, in a different embodiment not shown, the rear edge of eachoutlet hole 18 is straight (i.e. defined by a straight segment). - In a preferred embodiment,
delivery pipes 6,cross mixer 7, andfeed pipes 5 are defined in a single one-piece body 19 (i.e. formed in one seamless, indivisible piece) injection-molded from plastic material (e.g. polypropylene or polyethylene). One-piece body 19 preferably comprises a flat reinforcingportion 20 surroundingfeed pipes 5 on the inside and outside, and which haseyelets 21 on the outside for engagingrespective teeth 22 projecting from an edge oftank 2. The function of reinforcingportion 20 is to increase the strength of one-piece body 19 and connect one-piece body 19 easily totank 2. -
Defining delivery pipes 6,cross mixer 7, andfeed pipes 5 in a single one-piece injection-moldedbody 19 makeshydraulic circuit 4 cheaper to produce and cheaper and faster to assemble. -
Hydraulic system 4 as described above has numerous advantages, by being cheap and easy to produce and assemble, by having only modest load losses as a whole, and by operating extremely well, even when actual performance of the twosolenoid valves 12 regulating the twodelivery pipes 6 differs as a result of manufacturing tolerances. In other words, actual water flow alongcentral feed pipe 5 always equals the designed rated flow, even when actual performance of the twosolenoid valves 12 regulating the twodelivery pipes 6 differs as a result of manufacturing tolerances. Moreover, in addition to achieving the desired flow alongcentral feed pipe 5,hydraulic system 4 as described above provides for totally eliminating harmful dispersion alonglateral feed pipes 5.
