Definitions

  • the present invention relates to a washing machine comprising a filtering member for filtering the washing water.
  • washing machines In washing machines, the laundry is loaded into a drum disposed in a washing tub supplied with detergent-water mixture and is washed in the drum which is rotated. During the washing process, fibers separated from the laundry subjected to both mechanical and chemical effects are discharged, together with the water discharged at the end of the washing process, to the waste water line whereto the washing machine is connected. In traditional washing machines, each washing process causes approximately 1 milligram of fibers to be discharged to the waste water line. It is determined that more than half of microplastic accumulation in the nature is caused by waste waters originating from washing machines. Especially, taking into account the damage caused by synthetic fibers and particles in the nature, it is observed that waste waters originating from washing machines causes a critical environmental pollution.
  • a washing machine comprising a filter which is positioned under the detergent dispenser.
  • a washing machine comprising a filter which is disposed into the detergent compartment.
  • the aim of the present invention is the realization of a washing machine wherein the clogging of the filter is automatically detected.
  • the washing machine realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a filtering member having a receptacle which receives the circulation water, at least one filter which is disposed in the receptacle and which filters the fibers and particles carried in the circulation water and an overflow outlet which is arranged on the receptacle and which enables some of the water to be discharged out of the receptacle when the receptacle is at least partially filled with water; a compartment wherein the water coming through the overflow outlet is filled; a level sensor which detects the level of the water filling in the compartment; and a control unit which determines a filling rate by detecting the rate of change for the level of the water in the compartment and which decides on the fullness status of the filter according to the filling rate.
  • the fullness status of the filter is detected with great accuracy.
  • the control unit operates the level sensor after the circulation water starts to be supplied to the filtering member so as to calculate the time required for the level of the water in the compartment reaching a predetermined limit level and determines the calculated time as the filling rate. Since the amount of water filling in the compartment increases as the filter is being filled, the level of the water in the compartment reaches the limit level gradually in a shorter time. Upon determining that the filling rate is smaller than a first critical filling rate predetermined by the producer, the control unit decides that the filter is almost completely filled, in other words clogged. Thus, the clogging status of the filter can be quickly detected.
  • control unit controls the circulation pump according to the detected fullness status of the filter.
  • suitable amount of circulation water is enabled to be continuously delivered to the filtering member.
  • control unit stops the circulation pump upon detecting that the filter is clogged.
  • the control unit operates the circulation pump by repeatedly opening and closing the same upon detecting the filling rate is smaller than a predetermined second critical filling rate.
  • the receptacle is prevented from overflowing in case the filter is partially clogged.
  • the control unit ensures that a fullness parameter showing the fullness status related to the determined filling rate is transmitted to the user by means of a user interface which allows the user to control and monitor the operation status of the control unit.
  • a fullness parameter precalculated by the producer related to each filling rate is saved in the memory of the control unit.
  • the control unit determines the fullness parameter determined corresponding to the calculated filling rate, and transmits the same to the user by means of the user interface.
  • the fullness parameter is a filling ratio which proportionally defines the fullness status of the filter for each filling rate.
  • the fullness parameter is a number of remaining cycles showing after how many cycles the filtering member must be replaced, which is determined corresponding to each filling rate.
  • the user is enabled to replace the filter at the right time.
  • a washing machine comprising a filtering member wherein the user can easily monitor the fullness status of the filter without manually checking the same.
  • the filter since the filter does not require to be frequently checked, the filter can be positioned at an inner region of the washing machine, for example behind the detergent dispenser wherein the cleaning agents are loaded, and can be concealed so as to be accessed when required.
  • Figure 1 - is the schematic view of the washing machine related to an embodiment of the present invention.
  • Figure 2 - is the exploded view of the filtering member related to an embodiment of the present invention.
  • Figure 3 - is the cross-sectional view of the filtering member, the compartment and the level sensor related to another embodiment of the present invention.
  • the washing machine (1) comprises a body (2); a tub (3) which is disposed in the body (2) and wherein the washing process is performed; a circulation line (5) wherein the water taken from the tub (3) is circulated by means of a circulation pump (4); and a filtering member (6) having at least one filter (7) which filters the circulation water taken from the circulation line (5), a receptacle (8) wherein the filter (7) is disposed, a water inlet (9) through which the water coming from the circulation line (5) is taken, and a water outlet (8) which is arranged on the receptacle (8) and which enables the water passing through the filter (7) to be discharged out of the receptacle (8).
  • the circulation pump (4) draws water from the tub (3) into the circulation line (5) and the drawn circulation water is delivered to the filtering member (6) through the circulation line (5).
  • the filtered circulation water is delivered back to the tub (3) or out of the body (2) to be discharged by means of a delivery line (16).
  • the filtering member (6) is disposed into a housing arranged on the body (2) so as to be accessed by the user. The user replaces the filtering member (6) with a new one when the filter (7) is full.
  • the washing machine (1) of the present invention comprises an overflow outlet (12) which is arranged on the receptacle (8) so as to be positioned before the water outlet (10) in the flow direction of the water and which enables some of the water in the receptacle (8) to be discharged out of the receptacle (8); a compartment (13) wherein the water coming through the overflow outlet (12) fills; a level sensor (14) which detects the level of the water in the compartment (13); and a control unit (15) which determines the fullness status of the filter (7) by calculating a filling rate related to the change of the level of the water in the compartment (13) with respect to time by means of the data received from the level sensor (14).
  • the control unit (15) operates the level sensor (14) after the circulation water starts to be delivered onto the filtering member (6) so as to monitor the level of the water in the compartment (13) increasing with respect to time, and determines a filling rate in proportion to the rate of increase of the water level.
  • the control unit (15) compares the determined filling rate with at least one reference filling rate prerecorded in the memory thereof, and detects the fullness status of the filter (7), for examples whether the filter (7) is empty, partially full or completely full.
  • the circulation water remaining in the compartment (13) is emptied by means of a hole (17) preferably arranged at the base of the compartment (13) under the effect of gravity.
  • the control unit (15) measures the time elapsing from the starting of the circulation pump (4) until the level of the water in the compartment (13) reaches a predetermined limit level so as to calculate the filling rate, and, if the calculated filling rate is smaller than a predetermined first critical filling rate, decides that the filter (7) is full.
  • the producer precalculates the time elapsing from the supply of the circulation water to the filtering member (6) as the circulation pump (4) is operated when the filter (7) is almost completely full until the water overflowing from the receptacle (8) reaches a predetermined critical level, which is saved in the memory of the control unit (15) as the first critical filling rate, for example 5 seconds.
  • the control unit (15) decides that the filter (7) is almost completely filled and clogged. Thus, the fullness status of the filter (7) is quickly detected.
  • control unit (15) regulates the operation of the circulation pump (4) according to the calculated filling rate.
  • the control unit (15) changes at least one operational parameter of the circulation pump (4) such as the operation time and idle time, operating power, speed, etc. according to different filling rates, in other words whether the filter (7) is open, partially clogged or completely clogged.
  • the flow rate of the water delivered onto the filtering member (6) through the circulation line (5) according to the clogging status of the filter (7), and the filtering process can be securely performed without overflowing the water in the receptacle (8).
  • the control unit (15) stops the circulation pump (4) if the filter (7) is detected to be full. Upon detecting that the filter (7) is almost completely clogged, the control unit (15) stops the operation of the circulation pump (4) and transmits the user fullness information via the interface indicating that the filtering member (6) must be replaced.
  • the filtering process is interrupted when the filter (7) is full, and the problems such as the circulation water overflowing from the filtering member (6) so as to flow back to the circulation line (5), mixing with the clean water, etc. are prevented.
  • the control unit (15) intermittently operates the circulation pump (4) if the calculated filling rate is smaller than a predetermined second critical filling rate.
  • the second critical filling rate for example as 20 seconds, is determined by the producer precalculating the time elapsing from the supply of the circulation water to the filtering member (6) as the circulation pump (4) is operated when the filter (7) is partially full until the water overflowing from the receptacle (8) reaches a predetermined critical level in the compartment (13).
