Definitions

  • the invention relates to a washing machine with a drum, with a drive for rotating the drum about a substantially horizontal axis of rotation and with an interior for receiving laundry. Furthermore, the washing machine has at least one rib arranged on the drum, which forms a rib chamber which is connected to the interior via at least one outlet opening. The washing machine is designed to supply water via the rib chamber and the outlet opening to the interior of the drum.
  • washing machines of this type are known.
  • the rib chambers are connected on the one hand via the aforementioned outlet openings with the interior of the drum, and on the other hand arranged on the drum shell inlet openings with the area outside the drum.
  • the rib chamber takes up water via the inlet openings on, which then emits them in the course of the further drum rotation on the outlet openings to the laundry.
  • washing machines with such scooping ribs require a relatively high level of water in the tub so that the ribs can dip into the water.
  • a high water level is undesirable in terms of water and energy consumption.
  • EP 1 693 500 also describes a device in which the ribs of the drum contain tanks that can be filled with a certain amount of water for unbalance compensation during centrifugation.
  • a filling device is provided on the front side of the drum.
  • a collecting device is arranged on the end face of the drum, which is connected to the rib chamber. Furthermore, an injection device is provided in the washing machine, with which water can be introduced into the collecting direction. In this case, the device is designed so that it is possible in this way to introduce water into the ribbed chamber and thus into the interior of the drum.
  • the drum chamber can be supplied even at low water level in the tub with water to achieve wetting of the laundry in the interior of the drum.
  • the collecting device preferably forms a collecting chamber open towards the axis of rotation of the drum. This collecting chamber is thus connected to the ribbed chamber, that trapped water in the collecting chamber flows into the ribbed chamber. In this way, the water in the collecting chamber can be safely collected even during the rotation of the drum.
  • inventive construction can be combined with an imbalance compensation of the type mentioned above.
  • substantially horizontal axis of rotation is understood to mean an axis of rotation which, in the case of a washing machine arranged horizontally on the horizontal surface as intended, occupies an angle of not more than 15 °, in particular not more than 5 °.
  • the "face” of the drum is the side of the drum opposite the user's door of the machine.
  • FIG. 1 illustrated embodiment of a washing machine has a drum 1, which is rotatable about a horizontal axis of rotation 4 of a drive 2 via a belt transmission 3.
  • a door 6 is arranged, via which the user can gain access to the interior 7 of the drum.
  • the tub 8 has a drainage area formed by the so-called sump 9 below the drum 1. From there, the water can be conveyed away via a drainage pump, not shown.
  • Fig. 1 For example, the fresh water supply, the mixing device for mixing detergent and the control of the device, which fulfill their usual functions in the illustrated washing machine, unless otherwise mentioned here.
  • a plurality of ribs 10 are arranged on the drum 1.
  • the ribs 10 are uniformly distributed around the circumference of the drum 1.
  • Each rib forms a protruding from the drum shell in the interior space 7 of the drum, which extends in its longitudinal direction parallel to the axis of rotation 4.
  • a collecting device 12 is provided, which is associated with an injection device 13. The structure and the task of these components will be explained below.
  • the collecting device 12 comprises an outer wall 14 which extends parallel to the end face 11 and which has a concentric arrangement with respect to the axis of rotation 4, preferably round, opening 15 (see. Fig. 2, 3rd ) owns.
  • the outer wall 14 has the shape of a regular triangle (or more than three ribs, the shape of a corresponding regular polygon), at the tips of the ribs 10 are located.
  • a collecting chamber 17 is formed between the outer wall 14 and the end face 11, which is radially outwardly closed, but radially inwardly towards the opening 15 and thus to the rotation axis 4 is open.
  • the collecting chamber 17 extends around the rotation axis 4, so that it is able to catch the water coming from the injection device 13 independently of the drum position.
  • a filling opening 20 is provided which connects the collecting chamber 17 with a rib chamber 21 formed by the rib.
  • the fin chamber 21 is formed in the space between the inner wall of the rib 10 and the shell of the drum 1. Radially outward, the ribbed chamber 21 is closed. Radially inwardly on the ribbed chamber one or (preferably) a plurality of outlet openings 22 are provided, via which the ribbed chamber 21 is connected to the interior 7 of the drum.
  • the injection device 13 is arranged stationarily in the device and has a nozzle 24 with which water can be injected into the opening 15, preferably as close as possible to the radially outer boundary of the opening 15.
  • the nozzle is arranged in the lowermost region of the opening 15, so that the injected water flows as directly as possible into the collecting chamber 17.
  • a pump 30 is provided to deliver water from the sump (9) to the injector 13.
  • the described arrangement serves to introduce water into the interior 7 of the drum 1.
  • the pump 30 is put into operation, so that the water passes from the sump 9 to the nozzle 24 of the injection device 13. From there, the water is injected into the collecting chamber 17.
  • the collecting chamber 17 extends radially outward in the region of the ribs than in the region between the ribs, the water injected in this way automatically collects at one of the ribs, at a low drum speed in each case at the lowermost rib, so that it reaches via the filling opening 20 in the ribbed chamber 21 can flow.
  • the rib 10 In the course of further rotation of the rib 10 from its lowermost position upwards, it takes with it the water in its ribbed chamber 21, wherein it begins to flow from the outlet openings 22 at a certain angle of rotation.
  • the filling opening 20 is arranged at a tangential end of the ribbed chamber 21, ie in the tangential direction 31 (FIG. Fig. 3 ) seen at the front or at the very back.
  • the drum 1 is rotated so that the filling opening 20 is in the direction of rotation "front" end of the ribbed chamber 21, the water collected in the ribbed chamber 21 can not or only to a small extent through the filling opening 20 into the collecting chamber 17 run back, whereby the scooping effect of the ribs is improved.
  • the water from the fin chamber 21 emptied through the outlet openings 22 into the interior 7 of the drum 1.
  • the size of the outlet openings 22 and the volume of the rib chamber 21 are dimensioned such that the Rib chamber 21 is completely emptied approximately at the end of a drum rotation.
  • a plurality of ribs 10 are provided, wherein the rib chambers 21 of the ribs 10 are connected to the collecting device 12. It is conceivable in principle but also to provide only a rib of this kind.
  • the catchment chamber 17 is common to all of the fins 10, i. all the ribs are connected to the same collecting chamber 17, and the collecting chamber 17 is not divided between the ribs 10, so that water, which could not flow into the rib chamber 21 of the respective lowest rib 10, can flow to the next rib in the course of the drum rotation, which is turned to the lowest position.
  • an unbalance compensation chamber 35 is provided at least in a part of the ribs 10, preferably in all the ribs 10 ( Fig. 1 and 3 ), which in their function one of the tanks 10 according to EP 1 693 500 equivalent.
  • the imbalance compensation chambers 35 are sealed off from the fin chambers 21.
  • Each unbalance compensation chamber 35 is connected via a connecting line (not shown) with a filler ring 36 (dashed in FIG Fig. 2 shown) connected to the end face 11 of the drum 1.
  • the filling rings 35 correspond functionally to the filling rings 13a, 13b, 13c of FIG EP 1 693 500 .
  • a second injection device 38 is provided (see. Fig. 2 ), whose nozzles those of the nozzles 21 of EP 1 693 500 correspond.
  • the filling rings 35 are arranged, for example, in the region of the opening 15 directly on the end face 11 of the drum 1, but may also be located on the outer wall 14.
