Definitions

  • the invention relates to a domestic appliance with an exhaust air outlet, to which an exhaust air duct can be connected, in particular a laundry drying device and an extractor hood.
  • the domestic appliance according to the invention has an exhaust air outlet, to which an exhaust air duct can be connected. Furthermore, the domestic appliance has at least one air condition sensor for detecting a physical property, in particular flow property, of the exhaust air, in particular of a flow resistance.
  • the air condition sensor is located behind the air outlet side (downstream) of an exhaust fan.
  • the domestic appliance further has a control unit which is set up to receive at least one air condition measurement value (eg pressure or speed) of the at least one air condition sensor and to determine an exhaust air flow condition of the exhaust air guidance duct depending on the height of the measured value.
  • the domestic appliance also has an exhaust duct test function as a separate operating mode, when activated, the domestic appliance under load the at least one air condition measured value sensed and determined by means of the control unit, the exhaust air flow state of the exhaust air duct.
  • the air condition sensor is preferably arranged close to the mouth of the exhaust air outlet.
  • the physical state (eg pressure, flow velocity) of the exhaust air duct (exhaust hose, pipe, shaft, etc.) can be determined.
  • the flow resistance can at least indirectly be deduced, for example, by means of the pressure level or a flow velocity in the internal exhaust air duct, in particular at the exhaust air outlet.
  • the pressure level at the exhaust air outlet - which is approximately equal to the value at the beginning of the exhaust air duct - corresponds to the atmospheric pressure of the exhaust air duct (negligible flow resistance). The higher the pressure level, the worse the venting effect.
  • Determining when there is a significant performance penalty is typically device-dependent and is most often predetermined and discontinued at the factory. For example, a substantial decrease in performance may occur when a drying time extension from the ideal or initial state of 15-25%, especially about 20%, or more occurs.
  • the distinction between these two state ranges for example, by falling below or exceeding a threshold value by the air condition measurement or a derived state value.
  • the first state region eg "exhaust air flow in order”
  • the further state region eg "exhaust air ducting deficient ".
  • the threshold value can be determined empirically, for example, and predefined at the factory.
  • the exhaust air flow state has at least three state regions, wherein the further state region is subdivided into a second state region and a third state region, wherein in the third state region the air state measured value has a measure which only limits operation of the domestic appliance Performance degradation than in the second state range allows.
  • the user can be given a warning, for example, of the occurrence of considerable exhaust air performance losses.
  • the second state area may then correspond to a warning area (eg "exhaust air duct deteriorated"), while the third state area corresponds to an already greater exhaust air power loss (eg "exhaust air duct deficient").
  • the domestic appliance is a laundry drying device and after activation of the exhaust duct test function with motor, but is operated without heating; As a result, the state determination can be carried out particularly well reproducible.
  • the control unit is set up after a predetermined number of actuations (eg 230 drying runs in a tumble dryer or washer-dryer) and / or after a predetermined period of time has elapsed since a last activation Exhaust duct test function (eg after one year) to issue an exhaust air test request display.
  • the exhaust air test request display indicates to a user that an exhaust air test (more precisely: a test of the state of the exhaust air duct) should be carried out.
  • the exhaust test request display may include, for example, a display in a display unit or a lighting up of a lamp.
  • control unit is set up to output an exhaust air test request display before a first activation of the exhaust air duct test function after connection of the domestic appliance.
  • a structurally conditioned state of the exhaust air duct can be analyzed.
  • the air condition sensor comprises a pressure sensor.
  • the air condition reading is then a pressure reading.
  • the pressure sensor comprises a differential pressure sensor for detecting a differential pressure between a pressure at the exhaust air outlet and an atmospheric pressure.
  • the pressure reading is then a pressure differential reading. This z. B. compensates an influence of the atmospheric pressure at the installation on the pressure measurement.
  • the air condition sensor may also include a volumetric flow sensor, e.g. B. an impeller anemometer.
  • the air condition reading is then an exhaust air velocity reading.
  • the domestic appliance has a plurality of sensor passages, in particular static pressure bores, in particular annularly arranged.
  • the domestic appliance has a plurality of air condition sensors.
  • the domestic appliance has an exhaust air duct.
  • FIG. 1 shows an exhaust air dryer 1 with selected components.
  • the structure of exhaust air dryers is basically well known and typically includes a drum housing 2 for receiving a rotatably mounted laundry drum (not shown), an internal exhaust duct 3, the drum housing 2 via an exhaust fan 4 to a relative to the exhaust fan 4 downstream exhaust outlet 5 leads. At the exhaust air outlet 5, an exhaust air duct 10 can be connected.
  • the tumble dryer 1 further has a control unit 6, by means of which various drying programs or operating modes selected and activated by a user on a control panel 7 can be controlled.
  • the control panel typically has various operating and display means on, z.
  • the tumble dryer 1 in addition to a differential pressure sensor 8, which is partially introduced by means of a static pressure bore in the exhaust duct 3 of the tumble dryer 1 near the exhaust outlet 5. This position corresponds to a position shortly before a start of the exhaust air duct 10, if one is connected.
  • the differential pressure sensor 8 is connected by means of a signal line 9 to the control unit 6.
  • the control unit 6 can receive sensed measured values (static pressure with respect to atmospheric pressure) from the pressure sensor 8.
  • the drying device 1 a basically known mode selector switch (not shown), which is now extended to the mode "exhaust check" o. ⁇ . In this mode, only the motor is running, no heating.
  • the user should preferably have the exhaust duct 10 connected. It needs no laundry to be filled.
  • a lint filter should preferably be removed or should be clean. The customer receives after activating this mode, eg. After about 15 seconds, a recommendation on a display unit (not shown) of the control panel 7.
  • this recommendation may read as follows:
  • state range i) corresponds to a lowest differential pressure range, eg. For example, [0; 150 - 200] Pa
  • state range ii) corresponds to a mean differential pressure range which follows the maximum value of the lowest differential pressure range, e.g. B.] 150-200; 250] Pa
  • state area iii) corresponds to a highest differential pressure range which follows the maximum value of the mean differential pressure range, e.g. B.] 250 ... ⁇ ] Pa.
  • the user should preferably this exhaust air duct measurement before a first operation (after connection of the device) and z. B. once a year and / or perform after 230 drying.
  • This can be stored in the control unit 6.
  • the user is made aware of the occurrence of the above conditions by a corresponding exhaust air test request display appears, for example, a message in the display unit (eg, analogously "Please carry out exhaust air control check") is displayed or a corresponding light (eg an LED) lights.
  • the user is given the opportunity to operate the household appliance 1 with optimal exhaust air power and thus also the best possible total power by analyzing the exhaust air management state. For this purpose, the user is given a particular opportunity to test its exhaust air duct and to improve it structurally. This improves the performance of the domestic appliance, in particular reduces energy consumption. The user also gets the opportunity to detect creeping contamination of the exhaust air duct.
  • the home appliance can also be a cooker hood.
