Definitions
- washing machine with a controllable fresh water inlet and method for operating such a washing machine
- the invention relates to a washing machine with a controllable fresh water inlet for at least two detergent chambers, which are arranged within a housing of a detergent dispenser and have an outlet for the mixture of detergent and water, which opens on a bottom surface of the housing, which leads to a Drain port for a detergent supply line to the tub of the washing machine is inclined towards, in which a laundry drum is mounted at least approximately horizontally.
- the invention also relates to a method for operating such a washing machine.
- washing machine is known from DE 27 24 426 A1.
- this washing machine contains an additional separate detergent chamber for additives, which are switched on a separate way, not on the bottom surface of the housing in the same area of the tub when you turn on a separate fresh water supply at a given time.
- DE 101 38 067 A1 discloses a method for operating a program-controlled washing machine.
- the known method is at the beginning of a washing process in a first step without moving the laundry a certain first amount of liquid without detergent via a directed to the inside of a cuff bypass on the laundry, in a second step with movement of the laundry a certain second amount of liquid via the main washing agent chamber together with detergent between the laundry drum and the tub and in a third step with movement of the laundry liquid without detergent continues to pass over the bypass directly to the laundry until the total accumulated amount of liquid is sufficient to completely wet the laundry.
- the bypass consists of a branched off from the inlet channel to Vorwaschschhunt water line, which can only lead a significantly smaller amount of water than the inlet channel itself. Therefore, the water supplied via this bypass of the cuff is in fact sufficient only to wet the cuff before the start of the drum rotation in accordance with the object on which the known method is based, so that the washing rubbing against the cuff during drum movement can not be damaged. Since only about 3.5 liters of water per minute can be added via such a Zupoundweg, the addition of water until the complete replenishment of the total amount in the known method to lengthy.
- the known Zutweg is within narrow pipes in the lid region of Waschschein Kunststoff Road and therefore remains airtight even after switching off the flow of fresh water airtight by water residues, so that a special line between the tub and the detergent must be present to the tub during the addition of water and To aerate detergent.
- the invention is based on the object to provide with simpler means and faster than the prior art in addition to the supply of the detergent required for the main wash as early as possible as much as the required total amount of liquid laundry.
- this object is achieved in a washing machine of the type mentioned above in that the bottom surface is divided into sub-areas which have differently directed to at least one of the other faces, deviating from the horizontal inclinations, and each sub-area is associated with at least one detergent chamber and in its deepest part has its own drain port.
- the feed path via a detergent chamber, which is rinsed in front of the main washing agent chamber, for the rapid supply of water.
- this detergent chamber itself was filled with a detergent, such as a prewash.
- a detergent such as a prewash.
- the dosage of the detergent is regularly considerably lower, so that unlike the initial contact with main detergent no discoloration of the laundry is to be feared during the initial rinsing of the prewash.
- the so-called pre-wash chamber is regularly unmarked, so free.
- An advantageous development of the invention has partial surfaces which are separated by raised ribs. As a result, larger amounts of water can be prevented from passing over on partial surfaces during a drop in length from which they pass into an undesired detergent feed line.
- the drain connections are coupled to the tub in different areas, so that no undesired feedback effects or mutual influences occur during the flushing in of the water and the detergent mixture.
- the first of the outflow connections should be guided to the rear region of the tub so that it is far away from the coupling of the second of the outflow connections in the front region of the tub, which is also provided according to another advantageous development.
- the first drain connection is connected via a detergent supply line in an upper region of the jacket of the tub, which brings with it the advantage that when the laundry drum is running the water-detergent mixture rushing to the drum shell swirls intensively, mixed and distributed becomes. Furthermore, it is advantageous that even small amounts of water-detergent mixture through the flood holes in the jacket of the laundry drum occur and get in small portions on the laundry.
- the second drain port is advantageously connected via a detergent supply line in an upper region of the cuff.
- a washing machine according to at least one of the above characteristics is operated according to claim 10 in an advantageous manner so that for the supply of fresh water - A -
- a first subset of fresh water through the Vorwaschschhunt is passed directly to the laundry, then while flushing the main detergent chamber, a second subset as a mixture of fresh water and main wash on one in the upper part of the Lye container coupled detergent supply line to the jacket of the laundry drum and to fill the total amount a third subset is performed as fresh water in a direct manner to the laundry.
- a mixture of fresh water and additives on the additive chamber is preferably added directly to the laundry.
- Empirically to be determined values are to be selected for the different subsets of feed water, which should preferably be between 4 and 7 liters for the first subset, between 5 and 7 liters for the second subset and at least 30 liters for the third subset.
- FIG. 1 is a front view of the relevant for the supply of water and detergent parts of a washing machine
- FIG. 2 shows a schematically illustrated arrangement for a detergent dispensing device and the supply of the respective subsets to the tub or to the laundry and
- Fig. 3 is a schematic front view of another embodiment of a Waschstoffein Whynd.
- a washing machine housing 1 By thin lines the outer boundaries of a washing machine housing 1 are indicated, which has on the front side a filling opening 2 for feeding and discharging the laundry in the laundry drum 3.
- the laundry drum 3 - not visible in detail here - is enclosed by the tub 4 and rotatably mounted therein about a horizontal axis. The orientation of this bearing axis can also deviate from the horizontal. in the Generally this is a forward tilt of less than 15 ° selected. Accordingly, then the tub 4 is inclined with its feed opening 5.
- a sleeve 6 For fluid-tight connection of the filling opening 2 in the machine housing 1 and the feed opening 5 in the tub 4 is a sleeve 6, which allows a certain mobility of the tub 4 relative to the machine housing 1.
- a detergent dispensing device 7 is arranged, which can be supplied with fresh water via supply lines from the rear side (not shown here).
- the fresh water supply can be controlled by solenoid valves not shown by a program device at selected times or depending on the level.
- the Waschstoffein faced worn 7 has its own housed in the machine housing 1 housing 8, which houses a drawer with multiple chambers for different detergents or additives (better seen in Fig. 3). Below the chambers of the inserted drawer is the bottom surface 9 of the housing 8, which in the prior art has a uniform inclination to a drain port out. In any case, the bottom surface 9 is located as a collecting surface below the outlets of the detergent chambers. In the illustrated embodiment of the invention, the bottom surface 9 is divided into two partial surfaces 10 and 1 1, each having a different slope from the other.
- the sub-area 10 is - as defined here - arranged below the pre-detergent and the additive chamber and serves as a collecting surface for their contents or supplied by them fresh water. Their inclination runs towards the discharge connection 12, so that all the liquid which is supplied through the prewash agent chamber or the additive medium chamber reaches the discharge connection 12 via the bottom with the inclined partial surface 10. This is connected by means of a detergent supply line 14 with an inlet 16 of the sleeve 6.
- the sub-area 1 1 is - as defined here - arranged below the main washing agent chamber and serves as a collecting surface for the mixture of fresh water and main wash.
- the inclination of the part surface 1 1 extends to the discharge port 13, so that all the liquid through which the main washing agent is rinsed out of this chamber, passes over the bottom with the inclined part surface 1 1 to the discharge port 13.
- This is connected by means of a detergent supply line 15 with the tub 4 so that the inlet 17 passes the detergent-water mixture between the coats of the laundry drum 3 and the tub 4.
- the not visible here outlet of the main washing agent chamber 21 is above the part surface 1 1, and passing from this chamber main detergent-water mixture flows from the inclination of the part surface 1 1 driven to the drain port 13 and from there via the detergent supply line 15 to the inlet 17 on the tub 4.
- the fresh water can from the domestic water network 22 and controlled by the solenoid valves 23 and 24 with simple water jets 25 and 26, are connected in the usual way jumps to remindsaug rejoin water, reach the Vorwaschffenschhunt 19 or the main washing agent chamber 21. If, however, both solenoid valves 23 and 24 are opened at the same time, a single (middle) resulting jet 27 is formed by the jets 25 and 26 emerging simultaneously from the magnetic valves, which impinges on the admixture chamber 20.
- the two faces 10 and 1 1 are separated at their adjacent sides by a rib 28 so that bubbly from the chambers 19 to 21 leaking water is not in the adjacent Part surface can transgress.
- a rib 28 can also be used be formed only in that the common areas near the border of the partial surfaces 10 and 1 1 are provided with a greater slope than the other areas.
- a Waschstoffein Hughes Road 7 shown in FIG. 3 may also be formed in such a way that for each washing or additive chamber 19 to 21 own partial surface 29 to 31 and a separate drain port 32 to 34 is provided. This can be used to differentiate water or a mixed with water and detergent / additive at any time within a wash program in a separate area of the tub 4 or the washing drum 3 are introduced. For this purpose, the sequence is 35 to 37 of each chamber 19 to 21 located above its own associated part surface 29 to 31.
- the washing machine according to the invention has several advantages over the prior art.
- the function of the Ein Hughes character for the detergent held safer because the rinse of detergents depending on the consistency of an adequate amount of water can be provided without having to take into account other functions.
- Due to the fast feeding of the water required for the main wash cycle the laundry moved in the laundry drum is optimally protected and brought into contact with well distributed detergent as quickly as possible. This allows the active washing process to be used earlier and the wash cycle and subsequent rinse cycles to be kept short, as otherwise impossible to achieve.
- the rinses run thereby even more intense.
- An overflow of the flushing device can be avoided because one of the drain connections is certainly free to drain excess water.
- the ventilation of the tub 4 is given without additional ventilation duct, because one of the two detergent supply lines is guaranteed to be unoccupied.
- the ventilation is considerably safer, because the cross-section of the unoccupied detergent supply line is in any case greater than an additional ventilation line between approximately the Waschstoffeinzziness worn and a high-lying part of a Abpumptechnisch, as usual in
