Definitions

  • the present invention relates to a method for testing the operation of washing machines.
  • one or more components thereof may become damaged, either because of user faults, or due to environmental factors. Damaged components cause a malfunctioning of the respective household appliance. According to the prior art, if a household appliance malfunctions, it is brought to technical service to find out the problematic component and to solve the problem.
  • a laundry machine system Said laundry machine comprises a timer button. The user sets the time to activate the machine using this button. This button also allows to switch the machine to a test mode comprising a series of steps. In this test mode, the water valves, motor, and pump of the machine are tested.
  • the present invention discloses a valve test method for washing machines comprising at least one control element; at least one warning element providing the user with information on the operative state of the machine; at least one valve providing water inlet; at least one detergent dispenser into which a washing agent is introduced; at least one door through which items to be washed are placed, and at least one control unit regulating the operation of the machine.
  • Said method comprises the steps of initiating the test process once the use of the control element in a determined order and/or combination is detected by the control unit on a software basis; supplying water to the machine throughout a predetermined time interval through a valve to be tested; checking if the water in the machine has reached a predetermined level; detecting a failure on the valve tested if the water present in the machine has not come to the predetermined level and terminating the test process by sending a signal to the warning element to indicate the presence of failure on the respective valve; or completing the test process if the water in the machine has come to the predetermined level.
  • the object of the present invention is to develop a method for testing the valves of a washing machine.
  • Another object of the present invention is to develop a method for testing the valve of a washing machine in the place where the machine is already situated.
  • a further object of the present invention is to develop a method by which the operation of the valve is tested by an authorized person.
  • washing machine control element (1, 2) door (3) valve (4) warning element (5) detergent dispenser (6) level sensor (7) washing compartment (8) initiation (10) door locking (11) lock check (12) water inlet (13) water-level check (14) failure sending (15) lock-failure sending (16) completion (17)
  • the washing machine (M), illustrated as a laundry washer in figures 1 and 2 comprises at least one control element (1, 2), which controls the operation of the machine (M) and may be in the form of at least one button or switch; at least one warning element (5) providing the user with information on the operative state of the machine (M); at least one valve (4) providing water inlet to the machine (M); at least one detergent dispenser (6) by which a washing agent is introduced to the machine (M); and at least one door (3), through which items to be washed are placed into the machine (M).
  • Said valve (4) may be at least one valve (e.g. hot water inlet valve, cold water inlet valve, prewash valve) which supplies wash and/or rinse water to the machine (M).
  • Said warning element (5) may comprise at least one speaker alerting the respective user in an audible manner, and/or at least one indicator (e.g. display, illuminant) warning the respective user visually.
  • valve test method developed according to the present invention, first the door (3) of the machine (M) is closed in order to test the valves (4) of the machine and the test process, of which an exemplary flowchart is shown in Figure 3 , is initiated (10), using the control elements (1, 2) in a predetermined order and/or combination.
  • This order and/or combination is detected on a software basis by at least one electronic control unit (not illustrated in figures), which is provided in the machine (M) and regulates the operation of the same (M).
  • water is supplied (13) to the machine (M) by means of a valve (4) to be tested throughout a predetermined time interval (preferably 15-45 seconds and specifically 30 seconds).
  • the test process is terminated (17). And if the water level in the machine (M) has reached a predetermined level in the step of checking the water level (14), the test is completed (17).
  • the step of checking the water level (14) in the machine (M) is performed preferably by means of at least one water-level sensor (7) disposed in the machine, or it may be conducted by the test person visually.
  • a point to be paid attention to during this test is to make sure that the machine (M) is connected to a water source during this test and that water is supplied to the machine (M) from the water source.
  • a test performed in a setting without water may falsely indicate a valve (4) failure.
  • the door (3) of the machine (M) is automatically locked once the test process is initiated (10). It is then checked if the door (3) is correctly locked (12). If the door (3) is not locked, a lock-error is indicated (16) on the warning element (5) and the test is terminated (19). If no lock error is detected, the test is proceeded with the step of supplying water from the valve (4).
  • the test process can be conducted by at least one remote control method via a network.
  • the test results are transmitted to the person conducting the test via the network.
  • the test process according to the present invention can be performed at a place and time only, which are determined by authorized persons. Thus, it is both ensured to test the machine (M) in situ (e.g. at home), and to prevent the machine (M) from being switched to the test mode by unauthorized persons.
