Definitions

  • the present invention relates to a water dispenser for washing machine, in particular for washing machine.
  • water should be directed cold and / or hot water from a distribution network outside, to one or more tanks filled with detergents, also designated as detergents, necessary for effective washing laundry in the machine bowl.
  • detergents also designated as detergents
  • a water dispenser comprising an organ rotary, coupled to motorized actuating means, which is suitable for selectively direct the water admitted through at least one water inlet, towards outlets directed respectively to the detergent tanks. According to the angular position of the rotary member of the distributor, the water can be thus directed to one or other of the detergent tanks, depending on the cycle programmed from the washing machine, before reaching the tank.
  • European patent application No. 0361003 does not provides no description of the means which ensure the emptying of the tank of the washing machine, and the possible recycling of the water inside the washing machine.
  • the means of emptying, and the means of recycling water are independent of distributor previously invoked, and require two separate pumps, hence the multiplication and dispersion of the organs.
  • a washing machine or the dishes provided a complex hydraulic distributor, which allows, depending on the position of its movable element, to selectively direct the water towards one or the other of several compartments filled with detergents, or drain the tank by means of a pump.
  • this dispenser allows a function water recycling, also called “recirculation”, consisting of pumping the water in the tank of the washing machine, and to reinject it in this tank, by spraying water on the laundry.
  • This known device therefore combines the orientation of the water towards the tanks filled with detergents, emptying the tank and recirculating, using the same components for all these functions and, in particular, the same water channeling elements, of relatively small section.
  • This disadvantage is compounded by the causes recycled water to pass through the detergent dispensers, instead of describe a circuit avoiding these bins.
  • the detergents and the textile fibers torn from the laundry create problems fouling and possible clogging of the circuit parts covered by recycled water, if these parts are of small section.
  • the present invention aims to remedy the drawbacks above, by providing a water dispenser which greatly improves the mechanical efficiency of the water recirculation function, vis-à-vis the washing machine, as well as the reliability of this recirculation, while retaining for the distributor, a relatively simple and economical structure.
  • the subject of the invention is essentially a water dispenser for a washing machine, of the type comprising a member rotary able to selectively direct water, admitted by at least one water inlet, to outlets directed respectively to suitable tanks to receive washing products, motorized actuating means being provided for controlling movement and positioning angle of the rotary member, the distributor being characterized in that it is associated with a recirculation block comprising a water inlet in coming from the washing machine tank, a first directed outlet to this tank, and a second outlet extended by a drain, as well as a mobile shutter that can be moved mechanically by the same motorized actuation means as the distributor, or hydraulically from an outlet of the water distributor.
  • the recirculation function is now dissociated hydraulically from the distribution of water to the detergent tanks, this which makes it possible to make the conduits traversed by recycled water with a large section, and without going through the product bins.
  • the large cross-sections of the recirculation avoid the risk of clogging, and increase the reliability of the device.
  • the invention thus provides, overall, an improvement notable washing results.
  • the rotary member is a shutter disc provided with an opening offset and mounted rotating under a channel support on which are formed several outlet channels, and in which are formed openings arranged in a circle or an arc of a circle coaxial with the disc shutter, which respectively open into the different channels of outlet, the eccentric opening of the shutter disc being able to be brought in correspondence with any of the openings associated with different output channels. So by spinning disc control shutter, it is possible to supply the various product tanks with water, via the output channels, one after the other.
  • the different openings of the support of channels are each equipped with a sealing bead, on which comes rub the shutter disc.
  • the bead sealing the opening opening into one of these extreme channels is preferably extended in the shape of a "bean" so as to avoid any overpressure in the device, during the passage of the last channel of output to the first output channel (for a given direction of rotation of the shutter disc).
  • the recirculation block has, in a form of particular embodiment, a housing of which a side face comprises the first outlet, directed towards the tank, and of which another side face has the second outlet, extended by the drain pipe, while that the movable shutter of said recirculation block is a valve mounted pivoting inside the chamber delimited by the housing, so as to be able to seal either of the two outputs. So the pump drain being placed hydraulically upstream of the inlet of the recirculation, this block will allow, depending on the position of its valve, either emptying the washing machine tank, i.e. recycling the water to this tank.
  • the recirculation block housing can be integral with the distributor channel support, and in particular be produced in one piece with this support, which allows to associate constructively the recirculation block and the distributor, even if their hydraulic circuits are separated according to the very principle of present invention.
  • the means actuators are common to the distributor and the recirculation.
  • these means include a electric motor coupled to a gear reducer, whose shaft outlet is linked in rotation with the valve disc of the distributor, thus with at least one cam which cooperates with a lever, provided with a toothed sector engaging with a pinion toothing integral with the pivoting valve of the recirculation block. The operation of the recirculation is thus mechanically synchronized with that of the shutter disc distributor.
  • the output shaft of the gear reducer can be linked by rotation with a second cam, which cooperates with a switch electric for determining the instantaneous position of the assembly consisting of the distributor and the recirculation block, with a view to the realization of a position control of the entire device.
  • FIG 1 very schematically shows a machine wash the laundry whose tub is partially indicated in 1, and also suggested by the indication of the circular door seal 2.
  • the washing machine is connected to a cold water inlet 3 and / or a hot water inlet 4, coming from an external network, and it includes a drain pipe 5.
  • This washing machine also has a plurality of trays 6 provided for receive washing products (detergents).
  • the washing machine also has a water dispenser shown diagrammatically at 7 in FIG. 1, associated with a recirculation block 8, these organs being detailed below with reference to FIGS. 2 and 3.
  • the cold water inlet 3 is connected, via a solenoid valve 9 and a cold water pipe 10, to an inlet of the distributor 7.
  • the hot water supply 4 is connected, via a solenoid valve 11 and a hot water pipe 12, to another inlet distributor 7.
  • the distributor 7 has a plurality of outputs 13, directed to the various product bins 6. Alternatively, as indicated in dotted at 14, the distributor 7 can also have an outlet similar, but intended for direct filling of the tank 1 (i.e. without the water passing through any of the product containers 6).
  • the recirculation block 8 has a first outlet 15 directed towards the upper part of the tank 1, and a second extended outlet 16 through the drain 5.
  • a drain pump 20 is interposed on the conduit 17.
  • a block of electrical switches 21, attached to the distributor 7, is connected in particular to a door safety contact 22, as well as to a heating element 23.
  • An electronic management system 24 is connected, by electrical connections 25, 26, 27 and 28 indicated in dashed lines, respectively to the cold water solenoid valve 9, to the water solenoid valve 11 hot, to the water distributor 7 and to the drain pump 20.
  • the distributor 7 includes in particular a channel support 29, disc-shaped, on which are formed, for example, four outlet channels 30, 31, 32 and 33, delimited by respective partitions which materialize the outlets 13 to the product bins 6.
  • channels 29 are formed circular openings 34, arranged in a circular arc and opening, respectively, in the different output channels 30 to 33.
  • a disc shutter 35 Under the channel support 29 is mounted rotating a disc shutter 35, carried by a perforated wheel 36 and provided with an opening eccentric 37, the assembly formed by the disc 35 and the wheel 36 (possibly assembled in one piece) being housed inside a volute 38, provided with a lateral water inlet opening 39.
  • the different openings 34 of the channel support 29 are each equipped with a sealing bead, on which the obturating disc 35.
  • the bead of the opening 34 associated with the last outlet channel 33 is extended in the shape of a "bean", as indicated in 40 in FIG. 3, towards the opening associated with the first outlet channel 30.
  • the recirculation block 8 has a housing 41, integral with the channel support 29.
  • a lateral face 41A of the housing 41 comprises the first outlet 15, directed to the tank 1, for recirculation.
  • Another lateral face 41 B of the same housing 41 comprises the second outlet 16 extended by the drain pipe 5, as well as the inlet 19, at which is connected the pipe 17 coming from the drain pump 20.
  • valve 43 Inside the chamber 42, delimited by the housing 41 of the recirculation block 8, is pivotally mounted a valve 43 provided with a hub 44.
  • the valve 43 can thus pivot between a first extreme position (shown in Figure 3), closing the second outlet 16, and another extreme position (not shown) closing the first outlet 15.
  • an actuating assembly 45 comprising an electric motor synchronous 46 and a gearbox 47 with gears.
  • the output shaft 48 the reduction unit 47 is linked in rotation by a flat with the wheel 36, so with the shutter disc 35.
  • the output shaft 48 carries a first cam (located under the output gear), which cooperates with a recirculation lever 49, mounted pivoting about an axis 50 parallel to said shaft 48.
  • the lever 49 On one of its arm, the lever 49 is provided with a toothed sector 51, engaged with a pinion teeth 52 formed on the hub 44 of the valve 43 of the block of recirculation 8.
  • the output shaft 48 also carries a second cam, which cooperates with an electrical switch 53, associated with a printed circuit 54 attached to the reduction unit 47.
  • an electrical switch 53 associated with a printed circuit 54 attached to the reduction unit 47.
  • the volute inlet 38 is extended by a part 55 serving as a guide and support for printed circuit 54, as well as for electrical connectors (not represented).
  • valve 43 of the recirculation block 8 is pivotally mounted along an axis 56 laterally offset from the axis of rotation 57 of the obturator disc 35, the two axes 56 and 57 being parallel.
  • the assembly consisting of distributor 7 and recirculation block 8 provides, from the same actuation assembly 45, the functions of water distribution in the product bins 6, as well as recirculation (i.e. recycling, with closed loop circuit) of the water contained in the tank 1 of the wash.
  • recirculation i.e. recycling, with closed loop circuit
  • water from external network, to which the washing machine is connected is allowed by the cold water 9 or hot water solenoid valve 11 as the case may be, and passes through the water inlet 39 of the volute 38, then through the perforated wheel 36 and the opening 37 of the shutter disc 35, and finally in that of the channels of outlet 30 to 33 whose opening 34 is located opposite opening 37 of the disc 35.
  • the sealing bead 40 in the form of "Bean” avoids any overpressure in the distributor 7, at the time of passage from the last output channel 33 to the first output channel 30.
  • the water can be channeled by the bead 40 towards the opening 34, associated with the last output channel 33, until one again reaches the opening 34 associated with the first outlet channel 30.
  • the angular differences between the output channels 30 and 31, 31 and 32, 32 and 33 are for example equal to 60 °, while the angular difference between the outlet channels 33 and 30 is 180 °.
  • the recirculation block 8 depending on the position of its valve 43, this authorizes the passage of water, admitted by entry 19, either by first outlet 15 to tank 1, i.e. via the second outlet 16 to the drain pipe 5.
  • the water passing through the outlet 15 is reinjected at high flow rate into the tank 1 of the washing machine, by forming jets symbolized by the arrows 58 of FIG. 1, which water the laundry with some force.
  • the hydraulic power of recirculation can be adapted or adjusted, for example by providing that the drain pump 20 is a multi-speed pump, one speed more high being chosen for recirculation.
  • the water distribution and recirculation functions are controlled by the cam profiles associated with the output shaft 48 of the actuating assembly 45.
  • the first cam which cooperates with the recirculation lever 49, mechanically synchronizes the function of recirculation with the distribution function.
  • the second cooperating cam with switch 53 indicates to the electronic management system 24 of the washing machine what is the instant position of the assembly distributor 7 and recirculation block 8, and thus makes it possible to control the orientation sequences of the water in the outputs 13 at "low flow", directed to the product bins 6, and in the outlets 15 and 16 at "large flow rate ”of block 8.
  • the printed circuit 54 ensures certain electrical connections between the components, this for the position control, the supply of the synchronous motor 46 and the control of certain valves located in the vicinity. This printed circuit 54 can also receive electronic components, to realize additional functions.
  • valve 43 or other mobile shutter of the recirculation block 8 can be actuated hydraulically, this partially or totally, by providing on the water distributor 7 a specific outlet 13 connected by a link direct hydraulics with recirculation block 8, and dedicated to control of said valve or shutter.
