Definitions

the invention relates to a washing machine with a tub for holding washing liquid for treating laundry, with a horizontally rotatably mounted in the tub drum for receiving the laundry, a motor for rotating the drum and a Umflut adopted for conveying the washing liquid from the lower region of the tub in the upper portion, based on the operational set-up position of the washing machine, wherein the Umflut shark comprises a pump, a conduit and a nozzle which is adapted to inject the washing liquid into the drum.
a washing machine with a flooding device which has a nozzle for a wide-spread jet. This allows a wide area within the drum to be sprayed. Since the nozzle has a large opening, the pump must provide a fairly large fluid delivery. Furthermore, it is not ensured that the rear drum space is reached by the jet, since due to the large opening only a so-called surge is expected.
the invention is therefore based on the object to provide a washing machine to improve the washing effect with an optimized flooding device.
the main advantage of the method according to the invention is that in a simple way, an improvement in the washing effect at about the same duration and amount of water, compared to a conventional washing machine with Umflut Road is achieved. Elaborate design measures are not necessary here, since only the control of the pump must be adapted to the special nozzle geometry.
the pump is adapted to supply the washing liquid with different delivery speeds of the nozzle, and the nozzle is adapted to form the shape of the exit jet differently depending on the conveying speed of the washing liquid. This ensures that the discharge jet is fed into several areas of the drum. Although this happens at different times, but a nearly complete admission to the laundry with flooded washing liquid is possible.
the pump is designed to provide at least a first and a second conveying speed.
the second conveying speed is higher than the first conveying speed. This can be influenced in a simple manner by means of a control device, the conveying speed and thus the discharge jet of the nozzle.
the pump is designed to provide delivery speeds in the range between 1 l / sec and 10 l / sec. With these conveying speeds or delivery rates, an optimal beam shape can be achieved in order to achieve at least almost the entire inner width and inner length of the drum.
the nozzle has a discharge opening which is widened in relation to an inlet opening, so that, as it were, an inverted funnel is formed.
the nozzle on the back, ie opposite the outlet opening, walls which are in the horizontal longitudinal section of the nozzle V-shaped at an obtuse angle to each other.
the nozzle has an approximately horizontal wall, so that a horizontally fan beam is provided. It is expedient that the angle is in the range of 100 ° to 170 °.
a flow body is arranged in the region of the outlet opening. This flow body interacts with the obtuse-angled rear walls attached to one another as required deflection or fanning of the outlet jet from the nozzle.
the flow body has the shape of a vertical cylinder. This is particularly simple and stable to install between the lower, horizontal wall and the upper, horizontal or obliquely upward wall. Furthermore, the curvature of the cladding region is particularly well suited for beam deflection.
the nozzle is arranged so that the liquid jet flows around the flow body at the first flow velocity and due to the flow characteristics behind the flow body combines into a single jet, which is directed approximately axially to the interior of the drum. This will direct a narrow jet into the rear drum area.
the nozzle is designed so that the liquid jet is deflected at the second, higher flow rate of the flow body against the back walls so that at least two separate beams can form. This causes a distribution of at least two laterally fanned rays in the front to middle region of the drum.
the separate beams are each directed obliquely in the direction of the drum shell.
a loading of the laundry in the lateral region of the drum is achieved.
Fig. 1 is a purely schematic representation of a washing machine 1, shown with a tub 2.
the position and direction information refer to the operational installation position of the washing machine 1.
a rotatably mounted and driven by an electric motor 13 drum 3 is arranged, which moves the laundry items located in the tub 2 8.
the drum 3 is made in the present embodiment of stainless steel and provided with a plurality of openings for the flooding.
the housing 4 has a loading opening 9, via which the interior of the drum 3 can be reached through the sealing sleeve 6.
the loading opening 9 can be closed by means of a door 5.
a radiator 7 is arranged, which can heat the washing liquid in the tub 2.
an inlet valve 15 is sketched, which provides the running in of the water from the supply network.
the water is passed through the connecting pipe 14 in the tub 2, wherein in the dispenser 11 entered detergent is flushed into the tub 2.
a drain device 12 which leads the spent washing liquid or the rinse water from the tub 2 to the drain line 12c, which usually opens into a sewer.
the control device 18 controls the inlet valve 15, the activity of the drain device 12, the drive motor 13, which is energized via the power unit or a frequency converter 16, and the radiator 7.
Pump 17a a circulating 17 mounted.
the pump 17a is connected to the drain pipe 12b at the inlet side and suction side, respectively, and can convey the washing liquid 19 therein to the nozzle 20 through the pipe 17b in the upper area.
the washing liquid 19 is injected or flows through the nozzle 20 onto the laundry items 8.
Fig. 2 shows the nozzle 20 in a single view from the exit side.
the connecting piece 21 can be seen, to which the circulating line 17b can be shot.
the nozzle 21 opens into the nozzle chamber 22, which is bounded by the upper wall 23, the lower wall 24 and the rear inclined walls 25, 26.
a flow body 28 is arranged approximately in the center, which is formed in connection with the rear walls 25, 26 for influencing the outlet jet 29a, 29b, 29c.
Fig. 3 shows the nozzle 20 in a side view.
the cylindrical flow body 28 is mounted in the opening region 27 at least approximately perpendicularly between the upper wall 23 and the lower wall 24.
the inlet opening 30, through which the washing liquid passes into the nozzle chamber, is located in the upper wall 23 in the rear region of the nozzle chamber 22.
Fig. 4 shows the nozzle 20 in a horizontal sectional view AA.
the washing liquid 19 introduced into the nozzle chamber 22 adjoins the rear, V-shaped walls and emerges there from the nozzle opening 27.
the second conveying speed is higher than a so-called first conveying speed at which this effect does not occur.
the flow body 28 is in this case an obstacle, which divides the washing liquid 19 into two separate outlet jets 29a, 29b. These rays 29a, 29b widen after exiting the nozzle 20 on, so that a wide distribution of the washing liquid 19 within the drum 3 takes place.
Fig. 5 shows the situation at the first, so-called low flow velocity.
the liquid 19 flows along the surface of the curved flow body 28 and unites behind the flow body into a single, substantially bundled outlet jet 29c.
This single beam 29c passes further into the rear region of the drum 3.
the direction or the beam shape can thus be varied without changing the nozzle only with different flow rates.
only the control device 17 must control the pump 17a, which is easily possible by programming.
