Definitions
- the present invention relates to a laundry care device with a heating element.
- laundry care appliances such as a washing machine
- wash liquor is heated during a laundry care operation to achieve sufficient laundry care success.
- a heating element is used, which is arranged in a tub of the laundry care device or outside of the tub in a pumping system. Due to the pumping system, wash liquor is pumped out of the tub, passed through a pipe and returned to the tub.
- the heating element may be disposed in the pumping system of the laundry machine to heat wash liquor in the pumping system.
- DE 40 24 559 A1 describes an electrically heatable instantaneous water heater for dishwashers and washing machines.
- a laundry care apparatus having a pumping system comprising a tub for receiving wash liquor, the tub comprising an inlet opening and a drain opening, a conduit connecting the inlet opening and the drain opening, a pump for pumping of washing liquor through the conduit, a power detecting element for detecting an electric power value of the pump, a heating element on the conduit for heating the washing liquor in the conduit, and a 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 electric power value of the pump falls below a predetermined electric power threshold value in order to prevent excessive heating of the heating element.
- the technical advantage is achieved that the heating element outside the tub in the pumping system of the laundry care device is arranged to heat the wash liquor in the line of the pumping system without the heating element is too hot.
- the tub When using heating elements in the tub of laundry care appliances, the tub comprises a recess for receiving the heating element.
- the so-called dead liquor collects to be heated by the heating element.
- the dead liquor can not come into contact with the laundry in the washing drum and is therefore not available for the laundry care process.
- the geometry of the tub can be advantageously adapted to perform the laundry care process with a minimum volume of wash liquor.
- the tub can be adjusted flow optimized to improve the flow behavior of the wash liquor from the tub.
- the heating element in the pumping system can be achieved that the heating process of the wash liquor can be performed with a low level of wash liquor in the tub. Since a small volume of wash liquor is used, the amount of heating energy needed to heat the wash liquor can be reduced.
- the heating element in the pumping system a shortening of the heating phase can be achieved. Since the tub and the pumping system are designed to optimize flow, wash liquor can be conducted past the heating element at a high flow rate. Due to the high flow rate of the wash liquor in the line, the heating element becomes effectively lapped by the wash liquor, whereby an advantageous release of heat from the heating element is ensured on the passing wash liquor.
- the electrical power of the pump can be detected.
- the detected electrical power of the pump is dependent on the amount of fluid delivered by the pump.
- the pump When the pumping system is completely filled with suds, the pump must deliver a large amount of fluid, which consumes a constant amount of power from the pump and is detected by the power sensing element. If a small amount of wash liquor is used in the pumping system, air or scrubber foam may be sucked by the pump. If air is sucked in by the pump, the flow consumed by the pump will be reduced.
- the control of the laundry-care appliance is designed such that the heating power of the heating element is reduced when the electrical power value of the pump detected by the power-detecting element falls below a predetermined electric power threshold value.
- the power sensing element is connected to the pump by a power sensing connection, such as a power sensing device. a data cable connected to detect the electrical power rating of the pump. The detected electric power value of the pump is transmitted to the control through an information connection.
- the control is connected to the heating element by a control connection to control the heating element in dependence on the detected electrical power value of the pump.
- a laundry care device may be provided with a heating element in the pumping system that effectively heats the wash liquor in the pumping system without causing excessive heating of the heating element by the presence of air in the line.
- the power detection element comprises a current sensor for detecting a supply current of the pump.
- the current sensor includes a switching resistor that senses 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 current of the pump depends on the amount of liquid pumped by the pump. If air or wash liquor from the tub is pumped by the pump through the line, then there is a reduction in the supply capacity of the pump. If the tub is completely emptied, and only air is sucked in, then this leads to a significant 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, then the control reduces the heating power of the heating element to prevent excessive heating of the heating element. Thus, effective heating of the wash liquor in the pumping system is ensured by the heating element.
- the heating element is designed as a continuous heating element.
- a continuous heating element ensures effective heating of the wash liquor in the pumping system during the laundry care process.
- the continuous heating element is designed to effectively heat the wash liquor in the pumping 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 pumping system and can thus be quickly supplied to the tub.
- the continuous heating element can heat the wash liquor in the circulating pump system to the desired target temperature with a high heat output within a short heating phase.
- the heating element comprises a flat heating which is arranged in the line or on the outside of the line.
- the technical advantage is achieved that an effective heating of the wash liquor is achieved in the line by the use of a flat heating in the line or on the outside of the line. If the flat heating is arranged in the line, then due to the direct contact between the flat heating and the wash liquor, a particularly effective heat transfer from the flat heating to the wash liquor is achieved, whereby a rapid and effective heating of the wash liquor in the line is achieved. If the flat heater is located on the outside of the line, then the flow of wash liquor in the line is not hindered by the flat heater. Due to the resulting high flow rate of the wash liquor in the pumping system, effective heating of the wash liquor is achieved.
- the heating element is arranged in the flow direction downstream of the pump on the line.
- the technical advantage is achieved that it is ensured by the arrangement of the heating element in the flow direction after the pump that the pump passes the wash liquor at a high flow rate to the heating element.
- the flow rate of the wash liquor in the line is particularly high in a section of the line which is arranged downstream of the pump, since the cross section of the line in the pressure region of the pump is usually less than the cross section in the suction region of the pump, where it is due the higher gas fractions of the two-phase flow to separate the gas phase lower flow velocities and thus requires a larger cross-section.
- the heating element Due to the high flow rate of the wash liquor, a large amount of heat can be dissipated from the heating element in the section of the line within a short time interval. As a result, the heating element can heat the wash liquor with a high heat output without the heating element heating up too much.
- the heating element is designed as an element of the pump.
- the technical advantage is achieved that a particularly effective heat transfer from the heating element to the wash liquor in the pumping system is made possible by the combination of heating element and pump.
- the wash liquor is passed through the line by the pump at a high flow rate. If the heating element is installed directly in the pump, e.g. in the vicinity of the pump outlet, the heat generated by the heating element can be delivered to the wash liquor at exactly the point at which the wash liquor has a maximum flow velocity. As a result, the heating element can heat the wash liquor with a high heating intensity, without the heating element heating up too much.
- the combination of heating element and pump in a common component also allows the space-saving installation of the components in the laundry care device.
- the pumping system comprises a temperature sensor for detecting a temperature of the wash liquor in the line, wherein the control element is designed to control the heating element as a function of the detected temperature.
- the technical advantage is achieved that the temperature of the wash liquor can be detected in the line by the temperature sensor, whereby the temperature of the wash liquor can be advantageously adjusted by the control of the heating element by the control. If the detected temperature of the wash liquor does not exceed a predetermined temperature threshold, then the control may increase the heating power of the heater to ensure sufficient heating of the wash liquor. If the detected temperature value of the wash liquor exceeds a predetermined temperature threshold, then the control may reduce the heating power of the heating element or completely shut off the heating element. As a result, effective heating of the wash liquor in the line can be ensured without the heating element being too hot.
- the pumping system comprises a level sensor, wherein the level sensor is adapted to detect a level of wash liquor in the tub, and wherein the control is configured to control the heating element in dependence on the detected level.
- the technical advantage is achieved that can be detected in the tub by the level sensor, the level of the wash liquor.
- the level sensor can detect the pressure of the column of the wash liquor on the bottom of the tub. The detected pressure correlates directly with the level of wash liquor in the tub. By using the level sensor can be ensured that there is always a sufficient amount of wash in the tub to prevent overheating of the heating element in the laundry care device.
- the pumping system comprises a flow sensor, wherein the flow sensor is adapted to detect a flow rate of wash liquor in a time interval in the conduit, wherein the flow sensor is formed on the basis of the detected flow rate of wash liquor in the time interval To determine heating elementerieiteitete amount of wash liquor, and wherein the control is configured to control the heating element in dependence on the detected strictlyigned guided amount of wash liquor.
- the technical advantage is achieved that an effective heating of the wash liquor can be ensured by the control of the heating element as a function of the detected flow rate of the wash liquor in the line, without causing excessive heating of the heating element.
- the controller may reduce the heating power of the heating element to prevent excessive heating of the heating element.
- the heating element can be operated with a high heating power, whereby a large Quantity of heat in a short time interval can be delivered to the passing wash liquor.
- the pumping system comprises a filter unit, wherein the filter unit is arranged in the line or at the discharge opening, and wherein the filter unit preferably comprises a lint filter for removing lint.
- the filter unit is designed to remove impurities, such as fluff, either in the line from the pumping system or at the discharge opening of the tub.
- the pumping system comprises a rotatably mounted washing drum for receiving laundry, wherein the tub is formed such that the installation space between the tub and the washing drum is reduced in order to minimize the dead volume of the tub.
- the technical advantage is achieved that can be dispensed with by the use of a heating element outside of the tub on a heating element in the tub.
- the tub may be geometrically advantageous in order to increase the efficiency of the laundry care process.
- the dead volume is the volume of the wash liquor in the tub that can not be used to wet the laundry in the wash tub because it is in a recess in the wash tub Lye container is located where a heating element can be attached. Since it is possible to dispense with the heating element in the recess of the tub, the recess of the tub is also not needed, which significantly reduces the dead volume of the tub. By reducing the dead volume of the tub, the washing process can be operated with a small amount of wash liquor, thereby reducing the amount of heat required to heat the wash liquor.
- the pumping system comprises a liquor storage for storing wash liquor
- the conduit comprises a first portion of the conduit for supplying the wash liquor from the tub into the liquor storage
- the conduit comprises a second portion of the conduit for supplying the wash liquor from the liquor storage in the tub includes.

- the technical advantage is achieved that the pump allows regulation of the flow velocity and flow direction as a function of the required heat output by the heating element. If low or high heat output is needed, then the pump can pump the wash liquor through the line at a low or high flow rate.
- the change in the direction of flow of the wash liquor by the pump may be advantageous to carry wash liquor from the line back into the tub.
- the inlet opening is arranged on the front side or on the upper side of the tub, wherein the outlet opening is arranged on the underside of the tub.
- the pumping system comprises a further pump which is integrated in the line.
- the technical advantage is achieved that an increased flow rate of the wash liquor is achieved in the line by the use of a further pump, whereby the heating power of the heating element can be increased.
