Definitions
- the invention relates to an automatically controlled washing machine with a detergent dispensing device arranged in the upper machine room, which contains at least one chamber for a hand-metered addition of a washing powder or washing liquid portion and for each chamber an inflow path for the supply of fresh water, with at least one Machine room arranged storage container for liquid or gel detergent auxiliary, which is associated with a device for automatically dosing the stored washing aid containing a transfer line for the supply of the dose to the tub of the washing machine.
- Such a washing machine is known from DE 34 03 622 A1.
- a reservoir for liquid detergents in the Waschstoffein argues behind the notorious chambers for keeping a hand-dose amount of detergent is arranged.
- the transfer line from the metering opens directly into the same way to the tub as the offset with hand-dosed auxiliary detergents fresh water.
- the detergent drawer housing it and the chambers requires movement from and back into the cavity of the housing of the detergent dispensing device.
- the automatically metered amount of detergent is kept in an intermediate container until it is acted upon by its own Frischwasserweg with fresh water and fed through a siphon of the transfer line.
- this metered detergent can be supplied by hand dosed detergent in a known manner from the housed in the upper engine room Waschscheinargues coupled the laundry treatment process.
- the known washing machine with a variety of additional facilities is complicated and leaves little room for the reservoir. Therefore, only relatively small quantities can be stored.
- the transfer line is integrated within a pressure transducer tube of a water level sensor. Since the pressure transducer tube must open very deep in the tub anyway, so that the water level can be safely sensed, thereby the outlet opening of the transfer line is always automatically below the liquor level, so that the always wetted opening is permanently flushed. Deposits of incrusting or gelling auxiliaries are therefore impossible. However, separate lines must be laid within the washing machine, so that the automatically metered amount of washing aid enters the tub. However, if the washing machine is not used for a long time, residues of the metered detergent can be deposited and solidified in the long pipe.
- the invention is therefore based on the object of equipping a washing machine mentioned at the beginning in such a way that the risk of harmful deposits is avoided in the case of automatic dosing of washing auxiliaries, without substantially increasing the expenditure for this. Furthermore, the shortest possible paths for an automatically metered detergent and freedom from maintenance for the storage device while avoiding the above-mentioned disadvantages should also be strived for.
- this object is achieved by the features of the characterizing part of claim 1 in that at least one of the inlet paths contains a bypass whose inlet side is fluidically connected to the inlet path and whose outlet side is connected to the transfer line.
- the bypass on the output side is coupled in close proximity to the reservoir to the transfer line. In this way, the cleaning of the entire length of the transfer line is given.
- the storage container is placed in a receiving space within the detergent dispenser. Then the space behind the drawer equipped with chambers for manual dosing can be used meaningfully. It is large enough to hold a sufficient amount of washing aid for up to twenty washes.
- the metering device, z. B. a metering pump can be arranged in the reservoir itself. The pressure side of the metering device is firmly connected to the transfer line to a chamber of the drawer or with the direct route to the tub.
- the transfer line is part of the Waschstoffein réelleein- direction and the reservoir by means of a coupling with the transfer line connectable.
- This measure decisively reduces the additional expenditure for the rinsing measures of the transfer line.
- the bypass is also part of the Waschstoffein réelleeinrich- device.
- the bypass and / or the transfer line can be formed as a cavity line in the ceiling region of a housing for the Waschstoffein Kunststoff adopted and possibly the bypass in the ceiling region of the housing to be connected directly to the transfer line.
- FIG. 1 shows a washing machine in a view from above with a detergent dispensing and storage device equipped according to the invention
- FIG. 2 shows another individual storage device for a washing machine equipped according to the invention with transfer lines and bypass lines for the delivery tion of detergent from a arranged behind the drawer reservoir.
- the housing 1 of the washing machine surrounds a tub 2, which extends in the housing 1 so far up that for the Waschstoffein réelle responded 3 is only the upper side lent remaining space within the housing 1 is available.
- the Waschstoffein réelle responded 3 has its own housing box 4, which extends from the front panel 1.1 of the housing 1 to its rear wall 1.2 and in which the drawer 5 is guided freely movable in the pulling direction 6 and in the direction of thrust 7.
- the drawer 5 has three open-top detergent chambers 8, 9 and 10 for pre-wash (8), main wash (9) and fabric softener (10).
- the fabric softening chamber 10 still has a siphon 1 1 (shown schematically).
- the rear ends of the chambers 8 and 9 and the siphon 10 open into a common downcomer 12, which leads the mixtures of washing aid and water, which can be passed from above into the chambers, in a manner not shown to the tub 2.
- One or more dosing lines 27, 28 can open into this space from storage containers 23, 24 for washing aids (not shown here), which are arranged in the upper space of the washing machine outside the detergent dispensing facility.
- this solution is advantageous because no further means for the guidance of the detergent additive cans must be provided.
- FIG. 1 Another solution is shown in FIG. 1.
- at least one fixed premixing chamber 13 for a dose of a liquid or gel detergent is integrated in the housing 4 of the detergent dispensing device 3.
- the premixing chamber or chambers 13 are adapted in their shape and size to the respective space still available behind the chambers 8 to 10 of the drawer 5 and remain fixed in the housing 4 in any case, even if the drawer 5 is moved.
- a dose of up to 500 ml of washing aid can be stored.
- premixing chamber 13 At the bottom of the premixing chamber 13 has a drain opening 14 with a siphon 15 as the chamber 10 for fabric softener.
- a corresponding number of suction lifters 15 with drainage openings 14 are provided, all of which open into the same downcomer 12.
- a solenoid valve assembly 16 may still be arranged for the loading of the chambers 8 to 10 and 13.
- the detergent dispensing device 3 are in known manner in the ceiling region of the housing 4.
- the solenoid valve assembly 16 is supplied via a central inlet 17 from a domestic water supply, not shown, with fresh water.
- the premixing chamber 13 has its own water inlet path.
- a storage device 22 On the right side of the upper space within the machine housing 1 of the available space there is filled by a storage device 22, the one or - as shown here - can accommodate two reservoirs 23 and 24.
- Each storage container is associated with a metering device 25, 26, which essentially comprises a pump.
- the suction side of each pump communicates with the interior of the associated reservoir 23, 24 and the pressure side of each pump with an associated transfer line 27 and 28.
- These lines 27 and 28 open - here together - in the premixing chamber 13, which is harmless when the second Dosing 26 is addressed only after the intermediate stored in the premixing 13 dose of the washing aid from the first reservoir 23 has already been rinsed. If, on the other hand, two fixed premix chambers are provided, then each of the transfer lines 27 and 28 can open into one of the premix chambers.
- bypass 29 and bypass 30 From the valve block 16 still lead two lines, bypass 29 and bypass 30, to the pressure sides of the metering devices 25 and 26. There they are coupled with their output sides 29.2 and 30.2 to the transfer lines 27 and 28.
- the bypasses have on the input side in the valve block 16 each connection to a supply path for the premixing chamber 13 or for one of the chambers 8 to 10, so that the bypass in question always leads fresh water when the associated chamber 8 or 9 or 10 or 13 is acted upon , The fresh water in the respective bypass 29 or 30 then flushes the associated transfer line 27 or 28 of any washing aid residues free.
- FIG. 2 shows another variant of the storage, metering and feeding of automatic doses of washing auxiliaries.
- a receiving device 31 for a storage container 32 is provided, which can be a transportable and marketable storage container and can be distributed by a detergent manufacturer.
- a metering device 33 is arranged, on the suction side of a Coupling part for the reservoir 32 used is connected (not shown here).
- the metering device 33 is connected to the transfer line 34, through which the metered detergent and the rinse liquid is fed directly through the downcomer 12 to the tub 2.
- the bypass 35 with its input side 35.1 connects the inlet 18.1 on the outlet side (35.2) with the transfer line 34, so that when the water supply in the inlet 18.1, the transfer line 34 is flushed of detergent residues.
- the supply lines 18.x and the bypass 35 are part of a cover part of the housing 4, not shown in detail, of the detergent dispensing device 3.
- the supply lines 18.1 and 18.2, which each carry water, are connected to the solenoid valves not shown in detail in the valve block 16 when the chamber 9 or 8 is to be rinsed. If the supply line 18.1 alone carries water, then the line 18.3 of this water begins according to the arrow 20 and forwards it into the chamber 9. Accordingly, the line 18.4 begins the water according to the arrow 19 from the supply line 18.2 and passes it to the chamber 8 on. If both feed lines 18.1 and 18.2 carry water, then a resulting jet forms in the free air gap corresponding to the arrow 21, which is collected by the line 18.5 and forwarded to the chamber 10.
- each flushing of the chamber 9 is thus applied via the bypass 35, the transfer line 34 with rinse water.
- This is harmless if no washing aid has been metered from the reservoir 32, but only a hand dose of detergent from the chamber 9 has been transferred to the tub 2.
- the dosing device 33 will carry a portion of liquid washing aid from the reservoir 32 into the downcomer 12. So that at the same time enough water is available for dilution of the auxiliary washing agent portion, the inflow path via the line 18.1 is also activated, feed water is supplied to the lye container 2 via the chamber 9 and the transfer line 34 is purged via the bypass 35.
- the construction of the metering devices 25, 26 and 33 is not shown in detail. It can either be formed according to the prior art from DE 34 03 622 A1 or in another way with delivery devices (solenoid valve, pump, shutter) for the washing agent supply from the reservoir 23, 24 and 32 either pressureless or pressurized.
