  • the object on which the invention is based is to provide a laundry care device in which washing liquor can be effectively heated by a heating element in a pumped circulation system.
  • a laundry care device with a pumping system that has a tub for receiving washing liquor, the tub comprising an inlet opening and a drain opening, a line connecting the inlet opening and the drain opening, a pump for pumping of washing liquor through the pipe, a power sensing element for sensing an electrical power value of the pump, a heating element on the pipe for heating the washing liquor in the pipe, and a Control element for controlling the heating element, wherein the control element is designed to reduce the heating power of the heating element when the detected electrical power value of the pump falls below a predetermined electrical power threshold value in order to prevent excessive heating of the heating element.
  • the heating element is arranged outside the tub in the pumping system of the laundry care device in order to heat the washing liquor in the line of the pumping system without the heating element heating up too much.
  • the tub When using heating elements in the tub of laundry care devices, the tub comprises a recess for receiving the heating element. Part of the washing liquor in the tub, the so-called dead liquor, collects in the recess in order to be heated by the heating element. However, the dead liquor cannot come into contact with the laundry in the washing drum and is therefore not available for the laundry care process.
  • the recess in the tub can be dispensed with.
  • the geometry of the tub can be advantageously adapted in order to carry out the laundry care process with a minimal volume of washing liquor.
  • the tub can be adjusted to optimize the flow in order to improve the drainage behavior of the detergent solution from the tub.
  • the heating element in the pumping system it can be achieved that the heating process of the washing liquor can be carried out with a low filling level of washing liquor in the tub. Since a small volume of wash liquor is used, the amount of heating energy required to heat the wash liquor can be reduced.
  • the heating phase can be shortened by using the heating element in the circulation system. Since the tub and the pumping system are designed in a flow-optimized manner, wash liquor can be conducted past the heating element at a high flow rate. Due to the high flow rate of the washing liquor in the line, the heating element effectively washed around by the washing liquor, whereby an advantageous transfer of heat from the heating element to the washing liquor flowing past is ensured.
  • the electrical power of the pump can be detected by the power detection element.
  • the recorded electrical power of the pump is dependent on the amount of liquid conveyed by the pump. If the pumping system is completely filled with washing liquor, the pump has to deliver a large amount of liquid, whereby a constantly high amount of current is consumed by the pump and recorded by the power measuring element.
  • the control of the laundry care device is designed such that the heating power of the heating element is reduced if the electrical power value of the pump detected by the power detection element falls below a predetermined electrical power threshold value.
  • the power sensing element is connected to the pump by a power sensing link such as a data cable to sense the electrical power value of the pump.
  • the detected electrical power value of the pump is transmitted to the control element through an information link.
  • the control element is connected to the heating element by a control connection in order to control the heating element as a function of the detected electrical power value of the pump.
  • a laundry care device can be provided with a heating element in the circulation system which effectively heats the washing liquor in the circulation system without the heating element being excessively heated due to the presence of air in the line.
  • the power detection element comprises a current sensor for detecting a supply current to the pump.
  • the current sensor includes a switching resistor that detects the supply current of the pump during a time interval. In particular, an amplitude of the alternating current applied to the pump can be detected by the current sensor.
  • the supply flow of the pump depends on the amount of liquid conveyed by the pump. If air or suds foam from the tub is pumped through the line by the pump, then the pump's supply capacity is reduced. If the tub is completely emptied and only air is sucked in, then this leads to a considerable reduction in the supply capacity of the pump. If the supply current value of the pump detected by the power detection element falls below a predetermined supply current threshold value, then the control element reduces the heating power of the heating element in order to prevent the heating element from heating up excessively. Effective heating of the washing liquor in the pumped circulation system is thus ensured by the heating element.
  • the heating element is designed as a continuous heating element.
  • the continuous heating element ensures effective heating of the washing liquor in the pumping system during the laundry care process.
  • the continuous heating element is designed to effectively heat wash liquor in the circulation system, since the heat given off by the heating element can be quickly removed from the wash liquor due to the high flow rate of the wash liquor in the circulation system and thus quickly supplied to the tub.
  • the continuous heating element can heat the wash liquor in the circulation system with a high heating power within a short heating phase to the desired target temperature.
  • the heating element comprises a flat heater which is arranged in the line or on the outside of the line.
  • the heating element is arranged on the line after the pump in the direction of flow.
  • the flow rate of the washing liquor in the line is particularly high in a section of the line which is arranged downstream of the pump in the direction of flow, since the cross-section of the line in the pressure area of the pump is usually less than the cross-section in the suction area of the pump, which is due to the higher gas proportions of the two-phase flow to separate the gas phase requires lower flow velocities and therefore a larger cross-section. Due to the high flow rate of the washing liquor, a large amount of heat can be removed from the heating element in the section of the line within a short time interval. As a result, the heating element can heat the washing liquor with a high heating power without the heating element being excessively heated.
  • the heating element is designed as an element of the pump.
  • connection of the heating element and pump enables particularly effective heat transfer from the heating element to the wash liquor in the pumping system.
  • the washing liquor is passed through the pipe at a high flow rate by the pump. If the heating element is built directly into the pump, e.g. in the vicinity of the pump outlet, then the heat generated by the heating element can be given off to the wash liquor at the exact point at which the wash liquor has a maximum flow rate. As a result, the heating element can heat the washing liquor with a high heating intensity without the heating element being overheated.
  • the combination of heating element and pump in a common component also enables the components to be installed in the laundry care device in a space-saving manner.
  • the pumping system comprises a temperature sensor for detecting a temperature of the washing liquor in the line, the control element being designed to control the heating element as a function of the detected temperature.
  • the temperature of the washing liquor in the line can be detected by the temperature sensor, whereby the temperature of the washing liquor can advantageously be set by controlling the heating element through the control element. If the detected temperature of the washing liquor does not exceed a predetermined temperature threshold value, then the control element can increase the heating power of the heating element in order to ensure sufficient heating of the washing liquor. If the detected temperature value of the washing liquor exceeds a predetermined temperature threshold value, then the control element can reduce the heating power of the heating element or switch off the heating element completely. As a result, effective heating of the washing liquor in the line can be ensured without the heating element heating up too much.
  • the pumping system includes a level sensor, the level sensor being designed to detect a level of washing liquor in the tub, and the control element being designed to control the heating element as a function of the detected level.
  • the fill level of the washing liquor in the tub can be detected by the filling level sensor. This prevents the washing liquor from being pumped out of the tub completely, which prevents the heating element from heating up too much.
  • the level sensor can detect the pressure of the column of washing liquor on the bottom of the tub. The detected pressure correlates directly with the level of washing liquor in the tub. By using the fill level sensor, it can be ensured that there is always a sufficient amount of washing liquor in the tub in order to prevent excessive heating of the heating element in the laundry care appliance.
  • the pumping system comprises a flow sensor, the flow sensor being designed to detect a flow rate of wash liquor in a time interval in the line, the flow sensor being designed based on the flow speed of wash liquor detected in the time interval at which To determine heating element bypassed amount of wash liquor, and wherein the control element is designed to control the heating element as a function of the detected bypassed amount of wash liquor.

  • a filter unit such as a lint filter
  • the filter unit is designed to remove impurities, such as lint, either in the line from the pumping system or at the drain opening of the tub.

  • the pumping system comprises a rotatably mounted washing drum for receiving laundry, the tub being designed in such a way that the installation space between the tub and the washing drum is reduced in order to minimize the dead volume of the tub.

  • the installation space that is to say the gap between tub and tub, is reduced in such a way that the dead volume of the tub is minimized.
  • the dead volume is the volume of the washing water in the tub that cannot be used to wet the laundry in the washing drum, as it is in a depression in the washing machine
  • the tub is located where a heating element can be attached.
  • the heating element in the recess of the tub can be dispensed with, the recess of the tub is also not required, which significantly reduces the dead volume of the tub.
  • the washing process can be operated with a small amount of wash liquor, which reduces the amount of heat required to heat the wash liquor.
  • the pumping system comprises a caustic tank for storing wash liquor, the line comprising a first section of the line for supplying the wash liquor from the tub into the caustic tank, and the line having a second section of the line for supplying the wash liquor Includes from the liquor storage in the tub.
  • the pump is designed to change the flow rate or the flow direction of the washing liquor in the pumped circulation system.
  • the pump enables the flow rate and flow direction to be regulated as a function of the heating power required by the heating element. If a low or high heating output is required, the pump can pump the washing liquor through the line at a low or high flow rate. The change in the direction of flow of the washing liquor through the pump can be advantageous in order to convey the washing liquor from the line back into the tub.
