Definitions

  • the invention relates to a household appliance, in particular a dishwasher, with a noise-generating, mechanical and / or hydraulic system and with a controller for controlling the system as part of a process flow.
  • noise-reduced In order to reduce the noise emissions of such devices, it has already been proposed to provide the user with "noise-reduced" programs, the selection of which causes the device to generate less noise during the course of the process.
  • noise-reduced operation is often only possible at the expense of process time or efficiency.
  • the household appliance has switching means with which the controller can be switched over during the course of the process from a first to a second operating mode and / or from the second to the first operating mode.
  • the two modes of operation differed in their noise emission, i.
  • the noise emission of the device during the process flow in the first operating mode differs from the noise emission of the device during the process flow in the second operating mode.
  • the device can therefore also during the process flow, preferably automatically, i. if it is already running, be switched between the quiet and the loud operation mode. This allows a needs-based control.
  • the controller has switching means with which the controller can be switched over during the course of the process from a first to a second operating mode and / or from the second to the first operating mode.
  • the two modes of operation differed in their noise emission, i.
  • the noise emission of the device during the process flow in the first operating mode differs from the noise emission of the device during the process flow in the second operating mode.
  • the device can therefore also during the process flow,
  • the device is operated in the noisy operating mode to then switch to the quieter operating mode when noisy operation is no longer desired.
  • the quieter mode affect only part of the process flow.
  • the said switching means may comprise sensors, advantageously a microphone, with which the noise level of the environment of the household appliance can be measured.
  • the switching means are preferably adapted to switch the control of the device between the first and second operating mode when the noise level exceeds or falls below a threshold value. In this way, the noise generation of the device can be automatically adapted to the ambient noise.
  • the switching means may be configured to change the control to the second operating mode to switch when the noise level of the environment is below the threshold, and / or to switch the controller to the first operating mode when the noise level exceeds the threshold. This will make the device louder if the noise in the environment is high anyway. However, if it gets quiet and the noise of the household appliance is more disturbing, the unit automatically switches to the quieter operating mode.
  • the switching means may include a clock and be configured to switch the controller depending on the time of day between the first and second operating modes. This allows the unit to run more quietly during rest periods (e.g., night time or midday rest).
  • the switching means may also comprise a light detector with which the light level (i.e., the brightness) of the environment of the household appliance can be measured.
  • the switching means are configured to switch the control of the device between the first and second operating modes when the level of illumination in the environment of the device exceeds or falls below a threshold.
  • the device will automatically be quieter when it gets dark, i. when it gets dark.
  • the device e.g. in an artificially lit basement room, it is quieter when it gets light, as a light up indicates that a person has entered the room.
  • the household appliance may have an input element, such as a button or a switch, with which the control can be switched by the user between the first into the second operating mode. In this way, the user himself can determine when loud operation is tolerable.
  • an input element such as a button or a switch
  • process flow refers to a period of time during which the device is actively in operation. In a dishwasher this is e.g. the amount of time that the dishes are actively cleaned and dried until the user sees the progress of the process.
  • Fig. 1 the invention is illustrated by means of a dishwasher.
  • a tub 1 for receiving items to be washed.
  • different spraying means such as a lower spray arm 2, an upper spray arm 3 and a ceiling nozzle 4 are provided to pressurize the dishes with process water.
  • a circulation pump 5 serves to convey the process water from a sump 6 of the device to the spraying means 2, 3 and 4.
  • a switching valve 7 is provided, with which the process water can be selectively guided to individual or more of the spray.
  • the device has a drain pump 8, with which no longer required process water from the Sump 6 can be pumped, and a fresh water supply comprising a valve 9 and a treatment plant 10 to supply the device fresh water.
  • the various actuators of the device in particular the pumps 5, 8, the valves 7 and 9 and the treatment plant 10 are controlled by a controller 11 of the device.
  • the noise emission can also be influenced by other means, for example by the flow rate through the fresh water valve 9 being selected to be large or small or the temperature being driven higher or lower. (At higher temperatures, the foaming tendency is increased, leading to greater noise generation in the circulation pump.) It may also be desirable for all actuators to be turned off for a limited period of time and to be continued until after a standstill delay.
  • switching means are provided. Some examples of such switching means are discussed below.
  • Fig. 2 11 shows a view of the controller 11 and the switching means 12.
  • the switching means 12 may be at least partially formed by the controller 11 itself, eg as parts of the software of the controller 11, but may also comprise components external to the controller 11.
  • the switching means 12 have a switching means control part 14, which is designed for example as part of the controller 11, and one or more control elements 15 - 18.
  • the controls 15 - 18 may be provided, or it may a plurality of controls 15-18 are used, each of which may be used to switch the operating mode.
  • Fig. 2 Examples shown are described below.
  • the switching means 12 may comprise one or more microphones 15.
  • the microphones can be part of the device or it can also be used at least one external microphone, which wired or wireless (eg by radio or infrared) of the controller 11 transmits its signals. With this, the noise level of the environment of the household appliance can be measured.
  • the switching means 12 are designed such that they switch the controller 11 and thus the device depending on the signal of the microphone 15 from the first to second and / or from the second to the first operating state.
  • the switching preferably takes place as a function of the noise level of the environment. If this noise level is high, the unit is switched to the first (noisier) operating mode. If the noise level is low, it is switched to the second (quieter) operating mode.
  • the high noise generating parts of the household appliance eg the pump 5
  • the device is thus designed to operate during the measurement of the noise level at least a portion of the noise-generating parts of the household appliance or (compared to the normal operation) only reduced to operate.
  • an external wireless microphone could permanently determine the level in the room and influence the controller 11.
  • the microphone 15 may e.g. be integrated in a panel of the device.
  • the microphone 15 detects the noise level in the environment of the dishwasher.
  • the unit operates in the first operating mode with a high level of noise emission.
  • the pumps are operated at full power, and the switching valve 7 can be switched to produce a strong spray noise.
  • the controller 11 reduces the noise level, ie the device changes to the second operating mode so that it adapts to the environment. The term is extended to maintain the cleaning performance.
  • the device or the controller 11 is converted by the switching means by a first external stimulus (decrease of the noise level) from the first to the second operating state, and in the presence of a second external stimulus (increase in the noise level), but at the latest after expiry of a certain time, again transferred from the second to the first operating state.
  • the switching means may have a clock 17 indicating the time of day.
  • the device may in this case be switched between modes of operation, e.g. to achieve the quietest possible operation at night.
  • the switching means may comprise a light detector 16. This is able to measure the light level in the environment of the household appliance. In this way, the device can switch between the first and second modes of operation, depending on how bright the environment is.
  • the light detector 16 may be e.g. be integrated in a panel of the device.
  • the switching means may further comprise an input element 18, e.g. in the form of a button or switch (“mute button”) which allows the user to manually switch between the first and second modes of operation during the process.
  • an input element e.g. in the form of a button or switch (“mute button") which allows the user to manually switch between the first and second modes of operation during the process.
  • the input element 18 may be e.g. be provided as a supplement to the sensors 15 and 16. With the input element 18, the user can intervene directly in the process. As soon as the noise from the appliance for the dishwasher becomes too loud for a selected standard program, this can be converted by operation of the input element 18, the device in the second operating mode.
  • a very low noise operating mode is used; in high ambient noise, between 08:00 and 20:00, it is the highest noise operating mode, and otherwise a medium noise operating mode ,
  • the number of operating modes can in principle be so great that a continuous adjustment of the noise emission is possible.
  • the switching means can be used so that the household appliance in the perception is always quiet, i. his business does not bother.
  • the process flow is not unnecessarily extended. Especially in the evening to advanced hour, the remaining time of the device is of minor importance.
  • the programs can also be optimally designed according to the time of day.
  • the switching means 12, i. automatic switching between modes of operation may be selectively activated or deactivated by the user, e.g. by the input element 18 is operated outside a program sequence.
  • the second operating mode has lower energy consumption (over the entire process) than the first operating mode, energy can also be saved by the present solution.
  • hysteresis or filtering is preferably incorporated in the switching means 12, or the time between two switching operations is limited downwards.
