Definitions

  • the invention relates to a washing drum with drivers folded or embossed in the course of the drum jacket, which pour onto the laundry from a lower position in the tub and after further rotation of the washing drum from a higher position through openings arranged in the driver flanks or ridges onto a washing drum that can be loaded on the casing side, the loading opening of which can be closed by at least one door hinged to the drum casing.
  • a similar washing drum is known from EP-A-245 721, in which, however, the drivers cannot be folded or embossed in the course of the drum casing because the casing is continuously shaped and contains scooping devices as cut and embossed sheet metal formations.
  • the drivers are shown as special, e.g. made of plastic, molded parts inserted from the inside into the drum. This version cannot be used for drivers that are folded or embossed in the drum casing.
  • openings are formed in the drivers, such that when the driver passes through the liquor, when the washing drum rotates, the liquor flows into the trough of the driver and, when the drum rotates further, in the region of the Drivers' apex flows out holes and so sprinkles the laundry with liquor.
  • the object of the application is to develop the state of the art in a washing drum mentioned at the outset, in particular to improve and simplify the scooping device so that it functions reliably and uniformly over a long period of time in a constant manner.
  • the invention solves this problem in that the drivers are covered towards the outside of the drum by a plate which runs at least approximately in the lateral surface and contains a scoop device having at least one scoop slot.
  • This type of training of drivers with scooping devices also enables washing drums to be scooped and de-watered, the drivers of which are folded or embossed in the course of the drum jacket. This training is simple and cheap at the same time and works consistently safely and evenly over a long period of time.
  • the scooping device contains at least one hood protruding from the outer surface, which has a slot facing the scooping direction.
  • a lye deflector extending into the driver is arranged.
  • the plate has at least one wall that extends into the driver and is held in its mounting position by a tie rod that breaks through the wall. As a result, the scoop is fastened in the driver in the simplest way.
  • the wall can advantageously extend transversely to the longitudinal extent of the driver and forms at least two chambers. At least two such walls can form even more such chambers, the outer ones of which are delimited by the drum bottoms.
  • the suds deflector can serve as a support for two walls delimiting a chamber. As a result, the risk of their damage when threading onto the tie rod is greatly reduced.
  • the scoop can consist of several chambers, each chamber being assigned a slot. This makes it easier to adjust the scooping and sprinkling effect depending on the direction of drum rotation.
  • a development of the invention can also serve this purpose, in which the slots of adjacent chambers point in different scooping directions.
  • the wall extends longitudinally to the longitudinal expansion of the driver and thereby divides the interior of the driver into two elongated chambers. This is the safest and most gentle way to attach the scoop in the driver.
  • the scoop slots can be located on both sides of the plate of the scoop device.
  • the counterweight is combined with the scoop device.
  • a handle recess is introduced into the plate.
  • the plate can also be part of a housing that can be inserted into the driver from the outside. In this way, an insert part with the greatest possible inherent rigidity can be prepared for the scoop device.
  • 1 and 2 consists of a housing with a plate 2 and a scoop slot 3, side and end walls 4, 5 and stiffening or retaining walls 6.
  • a tie rod 7 is guided through the tips of the triangular walls the drum bottoms of the washing drum pulls against the cylinder jacket 16.
  • the scooping device is held in the driver trough 8. If the washing drum now rotates in the direction of arrow 9, liquor flows into the space 11 of the scooping device in the direction of arrow 10 when the driver passes through the lower part of the tub (not shown) surrounding it. After turning the washing drum further, the space 11 under the plate 2 releases the lye onto the laundry from a higher position of the driver through the openings 12 in a flank 13 of the driver or in its ridge.
  • a lye deflector 14 on the one hand gives the scooping device 1 a hold in the driver trough 8 and also prevents the lye from flowing out prematurely from the space 11 to the outside of the drum.
  • a recess 15 is made, which serves as a hand recess for moving the washing drum by hand.
  • the one for attaching the scoop device in the driving trough 8 serving tie rod 7 can also be used by a filling as a mass balance for the loading opening of the washing drum.
  • FIG. 3 shows the operation of the scoop.
  • the washing drum 27 rotates here, for example, in the direction of the arrow 9, so that when the scoop device 1 is immersed in the liquor 17 located in the bottom of the tub 28 through the slot 3, liquor flows into the space 11 of the scoop device.
  • the washing drum continues to rotate, this lye is lifted up and rained on the laundry from a higher position through the openings 12 in the driver.
  • the scooping devices shown in Fig. 3 are only effective in one direction of rotation of the washing drum. If the washing drum is to be operated in a reversing manner and scooping in both directions of rotation, the scooping devices are to be inserted into the drivers in such a way that some scooping devices are effective in one direction of rotation and the other scooping devices in the other direction of rotation.
  • the washing drum shown can be loaded on the jacket side and has a loading opening 19 with two hinged lids 18 and 18 'which can be closed by the closure 20.
  • the scoop device 1 opposite the closure can be provided with additional masses.
  • the scooping device according to FIG. 4 only consists of the plate 2 and the side wall parts 4 - and not shown here - 5. Further ribs 6 can be provided to stiffen the scooping device.
  • the slot 3 is formed here by a hood 21 projecting outwards from the plate 2.
  • the lye deflector 14 arranged on the opposite side, together with the flank surfaces 22 of the side wall parts 4 and 5 or the ribs 6, allows a good fit in the trough of the driver 8 and prevents the lye from flowing out to the outside. At the same time, it also serves to stiffen the plate 2 and the walls 4 to 6.
  • the scooping device can also be formed so that there are several chambers 23, the hood 21 in one direction of rotation of the drum and the hood 21 'in the other direction of rotation of the drum as slots 3 scooping is effective and the Fill each chamber 23 'or 23 with lye, depending on the direction of rotation of the washing drum.
  • FIG. 6 shows, side wall parts 4 and 5 according to FIG. 5 are not absolutely necessary. If the scooping device is inserted into the trough of a driver that already has lateral boundary walls through the drum bottoms, the side walls 4 and 5 are unnecessary. The walls 6 are sufficient for securely holding the plate 2 on the tie rod 7.
  • the chambers 23 can be contained in the scoop device in a freely selected number and division. Each chamber must have a slot 3, which is formed by the hood 21 and the lower edge of the drum shell to the driver.
  • the 7 shows a scoop device with counterweight 24.
  • the trough of the driver is divided in two by a wall 25 in its longitudinal direction.
  • the plate 2 also contains - on both sides - hoods 21 and 21 ', so that the scoop is effective in both directions of rotation of the washing drum.
  • the plate 2 is also provided with a handle recess 15 here.
  • the counterweight 24 can be attached to the scoop from the same material as the scoop or as a special part 26 from a specifically heavier material.
  • the part 26 is preferably surrounded by the (plastic) material of the scoop device.
