Definitions

  • the present invention is based on a washing machine with a detergent dispenser and a detergent supply line leading to the tub, which has a free connection to the surrounding atmosphere, and an additional ventilation line connected to the tub.
  • the care products required for a wash cycle are deposited in an insert or a drawer in the dispenser before the program begins.
  • the winding device is regularly arranged in the upper area of the washing machine.
  • To hold different types and / or quantities of laundry care products there are several compartments that are automatically controlled and rinsed out during the individual washing program phases by means of fresh water that is fed to the washing machine in a valve-controlled manner from an external supply network.
  • the water / care agent mixture flows into the tub through a induction hose.
  • the laundry is fed into and removed from the washing machine via the loading opening in the appliance housing, which can be closed watertight by a door.
  • the door size is adapted to the laundry drum.
  • the tub with the drum and the induction bowl as well as their connections and hose connections are a tightly sealed system when the loading door is closed. Ventilation of the system is regularly provided for trouble-free and low-noise operation of the washing machine. Such aeration means that a pressure equalization can take place during the filling of the tub with water or wash liquor and during spinning. This is particularly necessary to reduce the noise caused by compression when spinning. In addition, pressure equalization also enables greater accuracy in regulating the liquid level in the tub.
  • the loading opening adapted to the drum is so wide that children can enter the appliance unsupervised.
  • the ventilation systems described above are often not sufficient to ventilate the tub when the washing machine is stopped and the door closed so that children who have climbed in can be prevented from suffocation.
  • washing machines of this size are equipped with additional emergency ventilation.
  • Emergency ventilation in washing machines from well-known manufacturers is implemented by means of a hose which is connected to the tub in a low area and is led upwards from there.
  • the opening of the hose which has a free connection to the atmosphere, lies above the tub or at least in the area of the upper limit of the tub.
  • Such an emergency ventilation is easy to implement, its installation does not pose any fundamental problems.
  • the efficiency of such a ventilation hose depends on its inner diameter. Adequate ventilation requires the hose to be wide. This results in the disadvantage that, without additional countermeasures, the operating noises penetrate outward through the hose in an almost undamped manner and thus significantly increase the noise level.
  • Another disadvantage is that water vapor and foam can escape to the outside via the ventilation hose.
  • the invention has for its object to provide an improved ventilation system that performs the function of supplying sufficient fresh air to the tub, in an effective manner and thereby prevents the escape of water vapor and foam to the outside and largely prevents the noise from the inside of the device to the outside suppressed so that the noise level does not increase noticeably when the washing machine is in operation.
  • the object is achieved by the features mentioned in the characterizing part of patent claim 1. Further advantageous embodiments of the invention are contained in the subclaims.
  • the additional ventilation line is connected to an opening provided as far up as possible on the tub and to a nozzle arranged as far up as possible on the detergent dispenser.
  • the detergent supply line is led from the detergent dispensing device to an inlet nozzle in the upper region of the tub, which is as far away from the ventilation nozzle that no water reservoir can form in the line. Both lines have a connection to the atmosphere via the detergent dispenser.
  • the detergent dispenser has a lower part and a cover resting on the lower part, and on the other hand the cover and / or its support surface for the lower part of the dispenser device with respect to a part adjoining the cover on the side and / or the lower part with air-permeable spacing spaces.
  • its cover has raised webs on its underside, which are aligned parallel to the spacing spaces, for splash-proof sealing of the detergent dispensing device.
  • the two lines, the detergent supply line and the ventilation line can best be arranged far apart from one another in that the detergent supply line is connected to an inlet socket arranged on the base of the tub and that the base of the tub has a chimney-like shape in the area of the inlet port.
  • a major advantage of the ventilation system according to the invention is that fresh air can be supplied by circulation.
  • a chimney-like extension of the base of the tub in the area of the inlet connector is provided in an embodiment of the invention.
  • the chimney-like extension can advantageously be part of a shape that stabilizes the tub.
  • Fig. 2 shows a detergent dispenser in a sectional front view
  • Fig. 3 is a rear view of a tub designed according to the invention.
  • FIG. 1 a washing machine 1 is shown from the side in section. As in FIGS. 2 and 3, only the components that are important for the functioning of the ventilation system according to the invention were included in this illustration.
  • the tub 2 and the laundry drum 5 rotatable therein about a horizontal axis have a front loading opening which is accessible from the outside via the door 4 in the housing of the washing machine 1.
  • An elastic sleeve seals the tub 2 against the housing 1, with the door 4 the tub 2 can be closed to the outside in a water-tight manner.
  • the detergent dispenser 6, a plastic component, is arranged directly under the cover plate of the washing machine 1 and is accessible via an opening in the cover 19, which is designed here as an operating panel, for filling with laundry care products. Program-controlled, the laundry care products are rinsed out by means of fresh water which is supplied from an external water supply system via the connection 18.
  • the bottom of the detergent dispenser 6 has a slope and opens into the outlet nozzle 11 for the detergent supply line 8. This is to the inlet nozzle 7 arranged at the rear upper area of the tub container 2 so that the formation of a water bag is excluded in any case and thus Passage opening can not be narrowed.
  • the inlet connector 7 on the tub 2 is laterally offset over a bead 17 formed in the tub bottom 3.
  • the ventilation nozzle 9 for the additional ventilation hose 10 is attached at the highest point on the front jacket edge of the tub 2.
  • the corresponding nozzle 12 is also integrally formed on the detergent dispenser 6 at a point as high as possible.
  • the hoses 8 and 10 guided from the suds container 2 to the detergent dispenser 6 are designed to be vibration-elastic in order to avoid the transmission of vibrations from the spring-loaded detergent container 2 to the detergent dispenser 6 permanently installed in the housing of the washing machine 1.
  • the connecting pieces 7 and 9 on the tub 2 are as far apart as possible on the edges of the tub shell 2.
  • the ventilation of the tub 2 in the lower area can be done by this arrangement in the shortest possible way through the vertical spaces formed by the tub 2 and the drum 5.
  • the air supply is additionally conveyed by the chimney-like formation of beads 17, which are formed in a star shape as stabilization in the base 3 of the tub anyway (see FIG. 3).
  • the atmospheric connection of the ventilation system takes place via air-permeable spacing spaces 14 in the detergent dispenser 6 between the edges of the cover 13 and those of the cover 19 (see FIG. 2).
  • the spacing spaces 14 surrounding the cover are oriented obliquely so that water penetrating into these spaces can run off more easily.
  • the spacing spaces 14 are formed in that the cover 13 of the detergent flushing device 6, which is flush with the cover 19 and is pivotably articulated thereon, rests only at two points at the front corners, so that the edge is no longer tightly sealed all around the lower housing part 16 or the cover 19 rests.
  • slot-like spacing spaces 14 are formed on all four sides of the cover 13, via which the ventilation system has free access to the atmosphere.
  • webs 15 are formed on the underside of the cover and are aligned parallel to the spacing spaces 14.
  • the large condensation areas in the detergent supply line 8 and the detergent dispenser 6 and the special design of the spacing spaces 14 in the detergent dispenser 6 prevent foam and water vapor from escaping when the washing machine 1 is in operation. also has the effect that the noise level during operation of the washing machine 1 is kept within narrow limits.
  • the invention is simple to implement. In particular, no additional components are required; the special arrangements and configurations of the elements which are used and which are essentially known can be implemented using methods customary in the industry.
  • the chimney-like extension 17 of the tub base 3 proposed in accordance with the invention in the area of the inlet nozzle 7 can also be implemented without additional effort, as shown in the example, by an existing shape with shape-stabilizing beads 17.
