Definitions
- the present invention is based on a method for introducing detergents in program-controlled washing machines by means of a detergent-liquid mixture flowing onto the preferably cylindrical and apertured drum casing of a laundry drum rotatably mounted in a tub about an at least approximately horizontal axis.
- Such a method is apparent from DE 43 42 627 C2 or DE 43 42 626 C2. It can be carried out with a washing machine which has a detergent dispenser which can be controlled with regard to the dispensing of detergent stored in it and a detergent supply line and a drive motor for the laundry drum which can be controlled with respect to its direction of rotation.
- the term detergent is here and hereinafter used in a simplified manner for all types of washing, care and rinsing agents that are commonly used in washing machines.
- the aspiration of the washing machine manufacturers is to use the detergents used for the washing process as effectively as possible and to avoid losses. Losses can be caused, for example, by the fact that undissolved detergent enters the drain line on the tub, is no longer dissolved and thus remains ineffective for the washing process.
- Umpumpsysteme in use for detergent recycling in the tub (eg DE 37 04 079 A1 and DE 35 40 741 A1).
- a circulation pump By means of a circulation pump, the free liquor is pumped out of the drainage point from the lowest point of the tub and transported to the upper area of the tub. It thus takes place a cycle of the wash liquor, the detergent is dissolved by the constant movement in the fleet.
- solutions are proposed to close the drain pipe to the lye or circulating pump during the washing process.
- the locking mechanism prevents unresolved detergent from settling in the drain port and thus is lost during the washing process.
- DE 100 65 404 A1 is cited. It is proposed to close the opening to the drain line by a buoyant body which is pressed against an annular projection in the drain opening of the tub. To improve the sealing effect of the buoyancy body is coated with rubber or with an elastic plastic. The buoyancy of the closure body is generated by the standing in the supply line to the return water column.
- a return tank is arranged, in which there is a standing above the liquor level of the freshly soaked detergent-water mixture water column and thus has the necessary to produce the force acting on the buoyant pressure level. About the return tank, the spent liquor is pumped out of the tub.
- the two above-described solutions have the common disadvantage that the washing machines are to equip to avoid or reduce detergent losses with expensive additional devices. These additional devices make such washing machines not inconsiderably expensive.
- Umpumpenclar is also disadvantageous that additional energy must be expended when operating the washing machine.
- the invention has for its object to provide for the reduction of detergent losses a method that can be implemented with very little material cost and requires no additional energy expenditure when operating the washing machine.
- the detergent-liquid mixture flows during a drive of the laundry drum in the preferred direction of rotation, the detergent-liquid mixture in a jet against the moving drum shell, that the jet impinges at a shallow angle on a portion of the drum shell, which is in the upper quarter of its cylindrical shape.
- the drum is moved counter to the direction of flow of the introduced detergent-liquid mixture in a preferred direction of rotation.
- a variant is to be preferred in which the down-flowing detergent-liquid mixture is kept away from the drain opening as long as possible.
- the dissolution of the detergent can be significantly improved without additional effort.
- a particularly good effect can be achieved with the method if the surface of the laundry drum has a swirl-enhancing surface, in particular has a structured jacket surface. This allows the detergent-liquid mixture with rotating drum long in the upper area, so far away from the drain opening, are kept.
- the method can be implemented with minimal effort because it is essentially characterized by a pure software solution. For the practical implementation of the method, no additional modules or fixtures are required.
- the method is applicable to washing machines in which the detergent-liquid mixture is not centrally directed from the top of the drum shell, and can be retrofitted by reprogramming or replacement of the program block.
- the detergent-liquid mixture flows approximately over the entire depth of the drum distributed on the drum shell.
- the incoming liquid flows more evenly over the drum shell, which promotes the dissolution of the detergent.
- the uniform distribution also causes more mixture can pass through the openings in the drum shell into the interior of the drum during the feeding.
- the laundry is thereby wetted faster.
- the wetting of the laundry can be further improved in that the openings in the drum shell in the preferred direction of rotation have a higher passability.
- the amount of the liquid impinging on the laundry material through the openings in the drum casing during the feeding phase is controllable, within limits, by means of control of the drum speed.
- the method according to the invention thus offers an additional possibility of designing the washing programs.
- Fig. 1 shows a washing machine in perspective
- Fig. 2 is a detail view of the upper portion of the drum shell.
- a washing machine 1 is shown in perspective from the front.
- the representation simplistic contains only the important for the function of the method according to the invention components.
- the tub 3 and the therein about a horizontal axis 14 rotatable laundry drum 4 have a feed opening, which can be closed by means of a door removed here.
- the detergent dispenser is arranged in the upper housing area next to the control panel 1.
- her horizontally forward pull-out drawer 2 the required detergent is deposited.
- the drawer 2 is divided into a plurality of chambers, which can be flushed programmatically by means of fresh water, which is supplied from an external water supply system.
- the bottom of the dispenser opens into an outlet nozzle for the detergent supply line 7.
- the flow direction of the detergent-liquid mixture is indicated by arrows 6.
- a drain opening 10 is provided at the lowest point of the tub 3, which is connected via a connected line with the drain pump 1 1.
- the detergent-liquid mixture is distributed over the width of the drum shell 13 (FIG. 2) introduced.
- the drum shell 13 Due to manufacturing raised raised webs (not shown), which prevent the incoming detergent-liquid mixture flows through the sides.
- the movement of the drum shell 13 is due to the preferential direction of rotation 8 of the laundry drum 4 of the flow direction 12 of the incoming detergent-liquid mixture directed against the liquid jet 12 from above at a shallow angle.
- the introduction of the detergent liquid mixture takes place in a region of the tub within the upper quarter of the drum cylinder.
- the through-flow openings 9 in the drum casing 13 are formed by gill-like forms in the form of a half-cone (see Fig. 2). This shape causes on the one hand a delayed drainage of the detergent-liquid mixture from the drum shell 13. On the other hand, by the thus-shaped openings 9 in the direction of rotation 8 of the drum 4 directed to a greater extent liquid in the interior of the drum. The moistening of the laundry is accelerated.
