Definitions

  • the present invention relates to a dryer wherein the malfunctions that occur during the drying process are identified.
  • sensors that control the parameters of the drying process are utilized in a laundry dryer and the pressure sensor detects the interruption of the dry air entering the drying chamber. Furthermore, the parameters detected by the pressure sensor are utilized in obtaining the optimum drying results, the amount of the dry air/circulating air is adjusted by a separating means according to the detected parameters.
  • JP2002233696 the stuffed condition of the lint filter is detected by a pressure sensor utilized in the dryer.
  • the aim of the present invention is the realization of a dryer wherein the malfunctions that occur during the drying process can be detected correctly and on time.
  • the laundry is emplaced in a drum rotated by a belt that is actuated by means of a motor and the fan that is rotated by the same motor activates the drying air in the circulation channel to be passed over the laundry.
  • the pressure variations of the drying air with respect to time in the circulation channel is monitored by a pressure sensor situated in the circulation channel and the malfunctions that might arise in the drying process such as the snapping or detaching of the belt, blockage of the filter, blockage of the air circulation channel, the motor or the fan not rotating, excess load or insufficient load are detected by means of the monitored pressure characteristics.
  • the pressure values measured by the pressure sensor for detecting malfunctions are compared to the predetermined data recorded by the producer including pressure-time curves that can be observed when probable malfunctions occur in the drying process and the pressure-time curves recorded for a normal drying process.
  • Figure 1 - is the schematic view of dryer.
  • Figures 2 to 11 - are the pressure-time graphs showing changes of the pressure in the air circulation channel with respect to time.
  • the dryer (1) comprises a drum (2) inside which the load (L) namely the laundry to be dried is emplaced, a motor (3) that actuates the drum (2) to provide its rotation, a transmission means (4) that transmits the motion of the motor (3) to the drum (2), an air outlet (5) situated in front of the drum (2) through which the drying cycle air is discharged, and an air inlet (6) situated on the rear side of the drum (2) into which the dehumidified and heated air is redelivered to the drum (2), a circulation channel (7) in which the drying cycle air circulates, a fan (8) providing the circulation of the air in the drying cycle, a filter (9) providing to remove the fibers from the drying air, a pressure sensor (10) that detects the pressure (P) of the drying air in the circulation channel (7), and a control card (11) that evaluates the data received from the pressure sensor (10).
  • control card (11) compares the curve of the drying air pressure (P) value variations with respect to time (t), measured by the pressure sensor (10), to the probable pressure (P) - time (t) curves formed when possible malfunctions occur in the drying process, as predetermined, recorded by the producer, to decide on which type of a malfunction has occurred.
  • the malfunctions that can occur in the dryer (1) during the drying process are the malfunctioning of the transmission means (4), for example the breaking, dislocation or loosening of the belt rotating the drum (2), blockage of the filter (9), blockage of the air inlet (6) or the air outlet (5) by the load (L), the motor (3) or the fan (8) not rotating, excess load (L), insufficient load (L), dry load (L) or absence of load (L) and the control card (11) determines which of these malfunctions has occurred.
  • the pressure (P) characteristic of the drying air in the circulation channel (7) is detected as regular pressure oscillations around a nominal pressure value (Pn) by the pressure sensor (10) as a result of the air with a certain pressure (P) being circulated by the fan (8) in the air circulation channel (7), the drum (2) rotating to move the load (L) and the airflow being partly hindered at certain time intervals by the load (L) moving in between the air inlet (6) and the air outlet (5) ( Figure 2).
  • the curve of the drying air pressure (P) value variations with respect to time (t) in the circulation channel (7) measured by the pressure sensor (10) is compared to the pressure (P) -time (t) curve ( Figure 2) of a prerecorded normal drying process by the control card (11) to determine whether there is a malfunction or not, then by comparing to the pressure (P) - time (t) curves of probable malfunctions, the decision is given for what type of malfunction has occurred.
  • the control card (11) decides that the transmission means (4) is not functioning, that e.g. the belt is broken or dislocated ( Figure 3).
  • the transmission means (4) is out of order, the motor (3) and the fan (8) continues to operate, carrying on the air flow in the circulation channel (7) but since the drum (2) has stopped and hence the load (L) in the drum (2) does not move, an un-oscillated pressure (P) characteristic with a nearly constant value is observed.
  • the control card (11) decides that the transmission means (4) does not rotate the drum (2) from time to time, e.g. the belt is loosened and functions partly ( Figure 4).
  • the transmission means (4) rotates the drum (2) irregularly, the air flow continues in the drum (2) since the motor (3) and the fan (8) continue functioning regularly, however since the load (L) moves irregularly, a pressure (P) characteristic composed of irregular oscillations is observed.
  • the control card (11) decides the blockage of the filter (9) ( Figure 5). In this case, the fan (8) continues to deliver air into the drum (2) but the blockage of the filter (8) by the fibers cause the pressure (P) to increase.
  • the pressure sensor (10) can be positioned before or after the filter (9) in the dryer (1) in the direction of the air flow.
