Definitions

  • the invention relates to a method for detecting the loading of a program-controlled Dishwasher with items to be washed, which can be stored in crockery baskets and the like in the washing container of the Put down the device and the spray arms assigned to the baskets with rinsing liquid is, the vibrations or generated during dishwashing in the washing container Noise from one or more acoustic sensors to adapt the washing program recorded and fed to the program control of the device. Furthermore, the Invention a dishwasher for performing the method.
  • Program-controlled dishwashers can be operated in an energy-saving manner by the electricity and water consumption in relation to the amount of water for washing in the washing container loaded dishes or dishes. It is known from EP 0 943 287 A1, Detecting electromagnetic waves and / or sound waves in the rinsing container of the device Arrange sensors at a large distance from each other, especially on a room diagonal, whereby the sensors are assigned transmitters, the light signals or acoustic Send out signals. If the transmitter now sends signals, they will be transmitted by the invited Some of the items to be washed are reflected and / or delayed if necessary Receiver (sensor). The temporal evaluation of the signals received by the sensors then provides information about the arrangement of the dishes or the amount of dishes.
  • the each The determined amount of dishes or load of dishes is registered and the selected washing program influenced in its flow. This can be done, for example, by one of the loads Corresponding supply of rinsing liquid into the rinsing container and by means of the load quantity adapted heating of the rinsing liquid happen.
  • a disadvantage of loading detection according to EP 0 943 287 A1 is that Crockery parts lying in the transmitter beam of the signal transmitters emit electromagnetic signals from the transmitters Reflect and deflect waves or sound waves, possibly behind Positioned dishes in the crockery basket despite the diagonal alignment of the transmitter and receiver is not recognized. The load detection is therefore inaccurate. That too in the aforementioned Alternative methods described in the publication for the detection of the loading quantity through capacity measurement, there is no practical solution.
  • a dishwasher likewise equipped with acoustic sensors according to DE 40 10 066 A1 uses acoustic sensors to monitor the rotation of the spray arms, for what the vibrations or noises generated when washing dishes in the washing container Spray jets can be evaluated. An automatic load detection is through this State of the art not suggested.
  • the state of the art includes a dishwasher in which the washing water circulates amount of rinsing water flowing back into the bottom tub of the rinsing container measured and from this it is deduced from the load quantity of the device.
  • a dishwasher in which the washing water circulates amount of rinsing water flowing back into the bottom tub of the rinsing container measured and from this it is deduced from the load quantity of the device.
  • Such a method is disadvantageous because the one to be fed to the washing container for dishwashing The amount of water cannot be adjusted to the actual load, but it is to be designed for a full load.
  • the invention has for its object a method and a dishwasher Execution of the method to specify with which loaded in the dishwasher Wash ware quickly and in terms of quantity and with regard to the load on the crockery basket safely recognized and the flushing operation can be adjusted accordingly.
  • a dishwasher (1) shown in a simplified representation in FIG. 1 or its Rinse tank (2) is in its program run on the type and amount of the loaded for rinsing Dishes (3), sh. Fig. 3, customizable. This takes place in cooperation with the device's own electronic program control (4) for processing and editing the corresponding dishwashing parameters in a manner known per se with memory and arithmetic unit (not shown) is formed.
  • the construction of a dishwasher (1) is general known. Characteristic of such a household or commercial use water-carrying device is the washing container (2) equipped with crockery baskets (5, 6) in which the baskets can be moved separately between assigned rinsing levels rotating spray arms (7, 8, 9) are arranged.
  • the crockery baskets (5, 6) for the dishes (3) to be washed are in the rinsing container (2) on runners (10) or the like. And for clearing and unloading the dishes and the Cutlery can be pulled out of the washing compartment (2).
  • a separate cutlery basket in one of the crockery baskets (5 and 6) is a cutlery drawer (11) according to FIGS. 1 and 2 with your own spray arm (9) in a separate uppermost washing level of the washing container (2) intended.
  • acoustic sensors (12, 13) outside the wash cabinet on the wash tank (2) provided in different washing levels.
  • the arrangement of the acoustic sensors is advantageously made such that it strikes the washing compartment (2) in the wall area Spray jets (14) of the spray arms (7, 8, 9) assigned to the basket are located.
  • two acoustic sensors (12, 13) are separately on the outside of the washing compartment (2) arranged, each acoustic sensor (12 or 13) its associated crockery basket correspondingly covers a certain spray jet area (15 or 16). The The respective sensor position is above the spray arm at the level of the dish rack the associated crockery basket provided.
  • the acoustic sensors (12, 13) communicate with the program control (4) of the device Evaluation device (not shown) connected downstream, which of the spray arms (7 to 9) vibrations or spray jet noises generated on the rinsing tank walls converted into evaluable signals. If the crockery baskets (5, 6) are not loaded are, vibration signals (17) are sensed according to FIGS. 2a, 2b. These signals point high amplitudes and an almost stable frequency response due to the spray arm rotation. In contrast, with loaded crockery baskets (Fig. 3) vibration signals (17 ') with the 4a, 4b generated curve shape.
  • the vibrations generated by the spray arms (7 to 9) on the wash tank walls are detected by the acoustic sensors (12, 13) and the amount of items to be washed is calculated from them in the washing compartment (2) and their basket allocation by evaluating the vibration signals (17, 17 ') determined.
  • the vibration signals (17, 17 ') are preferably one for each spray arm (7, 8 or 9) Korbes recorded separately according to amplitude and frequency and it is based on the Loading of the basket closed.
  • Basket signals could possibly also be a separate acoustic sensor for the cutlery drawer be provided, which is especially in the spray jet area of the cutlery basket spray arm (9) would have to be ordered.
  • the device's own program control (4) is determined by the course of the vibration signals (17, 17 ') controlled and initiate the selection of a suitable washing program for the detected load and / or determine the supply of the spray arms (7 to 9) with rinsing liquid.
  • Spray arm (7 to 9) is currently controlled when the water switch has no information reports about their current position.
  • the load is recognized therefore also advantageous at the beginning of the washing program, so that the washing technology Parameters such as water volume, temperature, chemistry, pressure, rinsing time, water change and the like. by appropriate data exchange with the electronic program control (4) can be set at an early stage.
  • the acoustic sensors (12, 13) communicate with the Dishwasher electronics.
