Definitions

  • the invention relates to a water supply and Waschschein Beingsystem for a washing machine according to the preamble of claim 1.
  • Modern washing machines have a detergent dispenser, which has a plurality of receiving chambers for detergents and care products, from which these funds are flushed program by fresh water supplied in the tub of the machine.
  • the detergent dispenser usually has always a receiving chamber for a prewash, a receiving chamber for the main detergent and an additional receiving chamber for a care or washing aid.
  • detergent dispensing systems are known in which disposable containers, for example in the form of capsule containers, which are insertable into the receiving chamber of the detergent dispenser box provided for the supply of portioned care or washing aids. (See, for example, Ex. EP 2 365 120 A1 )
  • washing machines are predominantly equipped with safety devices which, as a water protection system, ensure that water damage caused by the inflow of fresh water or by leaks within the machine is avoided.
  • a water protection system in practical use (Miele, WaterProof system), which, inter alia, in the DE 10 2010 037 720 A1 is described.
  • a double-walled safety hose is used, wherein the actual water inlet hose is surrounded by an outer tube.
  • the safety hose is preceded by a controllable valve device which has two solenoid valves which shut off the water supply directly to the stationary faucet. These two solenoid valves provide a double-fused water protection. If a solenoid valve is defective, in the event of leakage still the second inlet valve can be controlled by the water protection electronics of the device to prevent the further water supply.
  • washing machines are characterized in terms of water protection by a high safety standard and it can be used in these devices for the cleaning and post-treatment process, a variety of different detergents and care products.
  • a costly expenditure on components and also a relatively high, control-technical effort is necessary for this purpose.
  • the invention thus provides the problem of providing a water inlet and detergent dispensing system, by which the cost of components can be reduced and thus a washing machine can be offered at a lower overall cost.
  • the advantages that can be achieved with the invention are, in particular, that a price reduction for the device can take place through the changes in the water supply and detergent dispensing system, without undermining the safety with regard to water and leakage protection.
  • a simplified detergent dispenser with a likewise simplified water supply system can be used by the invention.
  • About the intended water gate only two waterways to the receiving chambers with the washing and care products to control, which also contributes to the simplification of the water supply system to the detergent dispenser and not least overall to reduce the control effort.
  • the program-like supply of fresh water in the detergent dispenser via an inlet valve of the water protection device and directly via a water switch, by means of the water supply to the receiving chambers for powdered and / or liquid laundry treatment and / or care agent is controlled.
  • the detergent dispenser includes a receiving chamber for receiving a detergent, which is provided for the cleaning process of the laundry to be treated in a main wash cycle. To this receiving chamber are followed by two additional receiving chambers, via which the washing and / or care products can be flushed according to the program.
  • This Wäsche awarenesss- and / or care agents can be filled manually or fed automatically by metering devices.
  • An advantageous application also offers the use of portioned in capsule containers laundry treatment and / or care products that can be used in the receiving chambers.
  • the program according to supply of fresh water to the receiving chambers in the detergent dispenser is via two above the receiving chambers arranged supply channels, so that depending on the position of the water switch always one of the two supply channels can be acted upon with water.
  • the supply channels to the receiving chambers are arranged and designed so that the incoming fresh water is fed into the receiving chamber for the main wash and depending on the position of the water switch simultaneously in one of the underlying receiving chambers for additional washing or care products on the arranged in the supply channels injectors ,
  • these receiving chambers are arranged in a known manner for capsule containers which can be used therein, in which the washing or care agents are contained in portions.
  • the amount of fresh water introduced in each case via the supply ducts into the receiving chambers can be set as a function of the number or by the dimensioning of the injection nozzles arranged in the supply ducts.
  • a preferred embodiment provides for the supply channels with their injection nozzles to be formed and designed in such a way that always 80 to 90% of the total amount of water intended for the particular flushing process is in the receiving chamber for the main wash cycle and 10 to 20% in each case into the two receiving chambers for additional washing - or care products can be initiated.
  • One embodiment relates to a washing machine which also has a hot water connection in addition to the cold water connection.
  • the water inlet of the already heated fresh water must not be controlled via the water switch, but can be fed directly into the bypass around the water switch directly into the feed channel, through which the intended for the main wash detergent is flushed.
  • a modified embodiment of the invention may also be used.
  • the fresh water can be passed, bypassing the receiving chamber for the main detergent via a correspondingly arranged inlet channel in the receiving chamber for the aftertreatment agent.
  • the inventive design and design of the water supply into the detergent dispenser and the delivery system for the laundry treatment detergent and / or care products of various kinds and in different combinations can be supplied to the treatment process in a washing machine.
  • FIG. 1 is a frontally loadable washing machine 1 of conventional design shown, in which in a known manner a pull-out detergent dispenser 2 is arranged in the control panel. Furthermore, the washing machine 1 is equipped with a pertinent known water protection system, which essentially a valve system 4 with two controllable inlet valves 41, 42, a safety hose 5 between the stationary water connection 3 and a connection device unspecified here at the washing machine 1 and at the bottom of the Device arranged collecting trough 10 includes.
  • the safety hose 5 has an enveloping hose 51 and a water inlet hose 52 arranged therein. Possibly.
  • Leakage water leaving the water inlet hose 52 or inside the machine passes into the collecting trough 10 and is detected there by an electronic monitoring device which, in conjunction with the control device 9, causes one of the inlet valves 41, 42 to close, so that no water can run in the event of a fault ,
  • the water inlet hose 52 is connected in this embodiment within the housing with a water diverter 6, which is designed as a water-conducting actuator and the receiving chambers 21, 23, 25 upstream in the detergent dispenser 2.
  • washing machine 1 controlling electronic control device 9 The operation of the washing machine 1 controlling electronic control device 9 is shown symbolically in the drawing. As the dashed lines illustrate, the inlet valves 41 and 42 and the water switch 6 control technology with the control device 9 in connection.
