Definitions
- the invention relates to a washing machine with a drum and with an injection nozzle for injecting water into the drum.
- the injection nozzle of such a washing machine should distribute the water as well as possible on the laundry. This can be relatively easily achieved by a nozzle with several very small nozzle openings. However, fine-pored nozzles tend to clog.
- EP 1 386 996 there is described an injection nozzle which has a feed channel which throws water onto a baffle from which it injects in different directions into the drum. In such a solution, however, the water falls approximately along a line on the laundry, resulting in uneven wetting.
- the injection nozzle allows a more uniform distribution of water.
- the injection nozzle has at least one tray with a bottom, a first side wall and a second side wall.
- the baffle wall first follows, then the first side wall, then the floor and then the second side wall.
- the baffle and the second side wall and the first side wall are located closer to the mouth of the feed channel than the bottom.
- a line L is defined parallel to the direction X.
- the mouth, the baffle, the second sidewall and the bottom are projected perpendicular to the direction X radially on this line L.
- the description now states that the projections of the baffle and the second sidewall on the line L are closer to the projection of the mouth than the projection of the bottom.
- FIG. 1 shows the relevant in the present context parts of a washing machine 1.
- the washing machine has a housing 2, in which a cylindrical tub 3 is arranged sprung.
- a drum 4 is provided for receiving the laundry.
- the drum 4 can be rotated about a horizontal axis of rotation 5 via a drive (not shown).
- a door 6 is provided transversely to the axis of rotation 5, the frame is connected via a flexible bellows 7 with the tub 3.
- an injection nozzle 8 is arranged in the bellows 7. This is about a in Fig. 1 invisible hose connected to a pump, through which water can be conveyed through the nozzle into the drum.
- FIG. 2 to 7 An advantageous embodiment of the injection nozzle 8 is in Fig. 2 to 7 shown.
- the embodiment shown consists of a one-piece plastic part. It has a tubular supply channel 10 through which water is introduced into the injection nozzle.
- the feed channel 10 opens via an orifice 11 in a distribution space 12.
- the distribution space 12 has an opening 13 towards the drum 5.
- the lower wall region of the distribution space 12 forms opposite the mouth 11 a baffle 14, which in particular in FIGS. 2 and 3 can be seen. This is inclined to the direction X, in such a way that at least part of the water falling from the feed channel 10 to the baffle 14 receives a velocity component in the Z direction. For this is the. Deflection wall 14 designed sloping towards the direction Z out.
- the trough 15 has a first side wall 16, which connects bent to the baffle 14.
- the first side wall 16 merges into a bottom 17 of the tub 15 in a rounding.
- the bottom 17 goes in turn in a rounding in a second side wall 18 of the tub 15 over.
- the distribution space 12 is closed by a substantially flat top wall 19. This stands, as in particular in Fig. 4 Visible, transversely, but not exactly perpendicular to the direction X - it rises to the opening 13 a little way up.
- the mouth 11 is arranged in the top wall 19.
- the second side wall 18 of the trough 15 extends to the top wall 19, in such a way that top wall 19 and second side wall 18 meet at an angle of approximately 90 °.
- the distribution space 12 is bounded by a rear wall 23 (see Fig. 4 ), which runs transversely to the direction Y.
- the rear wall 23 extends between the bottom 17 of the tub 15 and the top wall 19. It goes over at an acute angle in the top wall 19.
- Both the bottom 17 of the tub 15, as well as the baffle 14 go in each case a rounding in the rear wall 23 via.
- the baffle 14 extends to the top wall 19th
- the distribution space 12 is closed on all sides except for the areas of opening 13 and mouth 11.
- a lip 26 is arranged between the baffle 14 and the opening 13.
- the baffle 14 is farther from the mouth 11 than the lip 26, ie, the lip 26 is positioned slightly higher than the baffle 14. This will deliver more water to the tub 15 and avoid too much water directly from the baffle 14 through the opening 13 exits.
- the tub 15 is open to the opening 13.
- the edge 27 of the trough 15 adjoining the opening 13 is, seen in the direction X, At least as far from the mouth 11 as the bottom 17 of the tub 15, ie the edge 27 is not higher than the bottom of the trough 15. This ensures that after switching off the water circulation, the water from the tub 15 can drain completely.
- the injection nozzle 8 is arranged so that the direction X is substantially vertical.
- Fig. 8 One possible arrangement of the injection nozzle 8 in the bellows 7 is in Fig. 8 shown.
- an opening 40 is provided in the bellows 7, which receives the supply channel 10 of the injection nozzle 8, such that the distribution space 12 between the door 6 and bellows 7 comes to rest.
- the injection nozzle is designed as a molded part (of one or more materials), as for example in Fig. 2-7 is shown.
- a second embodiment of the injection nozzle 8 is in Fig. 9 shown.
- the injection nozzle 8 is formed integrally on the bellows 7, ie injection nozzle 12 and bellows 7 are made of the same material and were produced together, for example by means of molding.
- the injection nozzle is constructed asymmetrically in the direction Z.
- symmetrical structure as in Fig. 10 is shown, in which two baffles 14 are provided, which divide the coming of the feed channel 10 water jet into two sub-beams and deflect into two trays 15.
- the exact mass of the injector must be adjusted to the desired water flow rate. For example, at a flow rate of about 8 liters / minute, a feed channel having an inner diameter of 10 mm was used and the tub had in view after Fig. 3 a radius of curvature of about 11 mm. The rest of the mass can be true to scale FIGS. 2 to 7 be removed.
- the shape of the individual parts of the injection nozzle may vary.
- the baffle in the embodiment runs after Fig. 3 bent, but it can also be stretched.
- the transition between the side wall 18 or the rear wall 23 and the top wall 19 may also be curved or locally even interrupted.
Description
Die Erfindung betrifft eine Waschmaschine mit einer Trommel und mit einer Einspritzdüse zum Einspritzen von Wasser in die Trommel.The invention relates to a washing machine with a drum and with an injection nozzle for injecting water into the drum.
Die Einspritzdüse einer solchen Waschmaschine sollte das Wasser möglichst gut auf das Waschgut verteilen. Dies kann an sich durch eine Düse mit mehreren sehr kleinen Düsenöffnungen relativ einfach erreicht werden. Feinporige Düsen tendieren jedoch zum Verstopfen.The injection nozzle of such a washing machine should distribute the water as well as possible on the laundry. This can be relatively easily achieved by a nozzle with several very small nozzle openings. However, fine-pored nozzles tend to clog.
In
Es stellt sich deshalb die Aufgabe, eine Waschmaschine dieser Art bereitzustellen, deren Einspritzdüse eine gleichmässigere Verteilung des Wassers erlaubt.It is therefore the object to provide a washing machine of this type, the injection nozzle allows a more uniform distribution of water.
Diese Aufgabe wird durch die Waschmaschine nach Anspruch 1 erfüllt.This object is achieved by the washing machine according to
Die Ansprüche sowie auch die Beschreibung verweisen auf drei Richtungen X, Y und Z, um die relative Position der Teile der Einspritzdüse zu definieren. Diese Richtungen sind wie folgt definiert:
- Richtung X verläuft entlang der Richtung,
- Richtung Y steht quer (nicht notwendigerweise senkrecht) zur Richtung X und entspricht der Richtung, in welcher der Verteilraum zur Trommel hin offen ist.
- Richtung Z steht senkrecht zu den Richtungen X und Y.
- Direction X is along the direction
- Direction Y is transverse (not necessarily perpendicular) to direction X and corresponds to the direction in which the distribution space is open to the drum.
- Direction Z is perpendicular to the directions X and Y.
Gemäss Anspruch 1 besitzt die Einspritzdüse mindestens eine Wanne mit einem Boden, einer ersten Seitenwand und einer zweiten Seitenwand. In Richtung Z gesehen folgen dabei zuerst die Ablenkwand, dann die erste Seitenwand, dann der Boden und dann die zweite Seitenwand. In Richtung X gesehen sind die Ablenkwand und die zweite Seitenwand sowie die erste Seitenwand näher an der Mündung des Zuführkanals angeordnet als der Boden.According to
Dabei ist eine Umschreibung der Art "in Richtung X gesehen sind die Ablenkwand und die zweite Seitenwand näher an der Mündung des Zuführkanals angeordnet als der Boden" wie folgt zu verstehen: Es wird eine Linie L parallel zur Richtung X definiert. Die Mündung, die Ablenkwand, die zweite Seitenwand und der Boden werden senkrecht zur Richtung X radial auf diese Linie L projiziert. Die Umschreibung besagt nun, dass die Projektionen der Ablenkwand und der zweiten Seitenwand auf der Linie L näher zur Projektion der Mündung liegen als die Projektion des Bodens.In this case, a description of the type "seen in the X direction, the baffle and the second side wall closer to the mouth of the feed channel arranged as the ground" is to be understood as follows: A line L is defined parallel to the direction X. The mouth, the baffle, the second sidewall and the bottom are projected perpendicular to the direction X radially on this line L. The description now states that the projections of the baffle and the second sidewall on the line L are closer to the projection of the mouth than the projection of the bottom.
Durch die anspruchsgemässe Ausgestaltung wird einerseits erreicht, dass das Wasser, welches auf die Ablenkwand fällt, seitlich zur Wanne hin abgelenkt wird und gleichzeitig dort eine Verwirbelung erfährt. Wie es sich gezeigt hat, führt dies zu einem verwirbelten Wasserstrahl, der durch die Öffnung aus der Düse in die Trommel austritt und in einem grossen Streubereich auf die Wäsche fällt.Due to the claimed embodiment, on the one hand, it is achieved that the water, which falls on the baffle, is deflected laterally towards the trough and, at the same time, undergoes turbulence there. As it has been shown, this leads to a swirling jet of water, which exits through the opening from the nozzle into the drum and falls in a large range of scattering on the laundry.
