Definitions

  • the present invention relates to a fabric processing device, and in particular, to a machine having washing and drying functions, comprising a drum driven by an electric motor, a control device used for controlling execution of a spin-drying procedure and a subsequent heat-drying procedure, and a detection device for detecting a rotation speed of the drum or the electric motor.
  • the present invention further relates to a method for controlling a spin-drying procedure and a heat-drying procedure of a fabric processing device, comprising selecting and then starting to execute a spin-drying procedure and a subsequent heat-drying procedure.
  • the spin-drying procedure of the existing fabric processing devices often fails to be completely executed. For example, excessive high bubble detergent is put in the washing procedure, or serious imbalance is caused due to uneven load distribution in the spin-drying process. In these cases, an actual rotation speed in the spin-drying procedure usually fails to reach a predetermined target value, and thus a lot of water remains in the fabrics after the spin-drying procedure is ended. If the fabric processing devices enter the heat-drying procedure in this case, an established heat-drying goal may often fail to be achieved. For example, the fabrics maintain relatively high water content after the heat-drying procedure is ended.
  • An objective of the present invention is to remedy the foregoing defects of the fabric processing devices in the prior art, so that the fabric processing devices can instantly adjust the spin-drying procedure and/or the heat-drying procedure according to operation conditions of the spin-drying procedure.
  • the present invention provides solutions for a fabric processing device and a control method as defined in the attached independent claims.
  • Preferred embodiments of the invention are defined in dependent claims, the subsequent disclosure and the attached drawing.
  • Preferred embodiments of the fabric processing device imply preferred embodiments of the control method and vice versa, even if not elaborated upon in detail herein.
  • a fabric processing device includes a drum driven by an electric motor, a control device used for controlling execution of a spin-drying procedure and a subsequent heat-drying procedure, and a detection device for detecting a rotation speed of the drum or the electric motor, where when the spin-drying procedure and the heat-drying procedure are both selected, in the spin-drying procedure, if the detection device detects that the rotation speed of the drum or the electric motor fails to reach or remain stable at a first preset rotation speed S1 during a first preset time T1, the spin-drying procedure is ended, and the subsequent heat-drying procedure is cancelled.
  • the control device ends the spin-drying procedure and cancels the heat-drying procedure, to save unnecessary energy consumption. Meanwhile, users may properly adjust the fabrics, and reselect proper procedures for operation.
  • the spin-drying procedure already completed accounts for less than 60% of an entire process of the spin-drying procedure.
  • the fabrics contain much water, and thus are not suitable for heat-drying.
  • the rotation speed of the drum or the electric motor reaches the first preset rotation speed S1 and maintains the first preset rotation speed S1 during a first set time T1
  • the rotation speed is then increased; if the detection device detects that the rotation speed of the drum or the electric motor fails to reach or remain stable at a second preset rotation speed S2 during a second preset time T2, the spin-drying procedure is ended, and execution of the heat-drying procedure is directly started.
  • the spin-drying procedure has run sufficient time to enable the fabrics to be suitable for heat-drying. Ending the abnormal spin-drying procedure may save electrical energy and time.
  • the spin-drying procedure when the spin-drying procedure is ended and execution of the heat-drying procedure is started, the spin-drying procedure already completed accounts for at least 60% of the entire process of the spin-drying procedure. In such a process range, most water contained in the fabrics is removed, and thus the fabrics are suitable for heat-drying.
  • the fabric processing device includes a display device; where when the spin-drying procedure is ended, the display device displays a ratio of the spin-drying procedure already completed to the entire process of the spin-drying procedure. Users may understand operation conditions of the procedure according to displayed information.
  • the spin-drying procedure includes a plurality of incremental rotation speed steps; on these rotation speed steps, the electric motor and the drum maintain a corresponding rotation speed during set times T1 to T5; when the spin-drying procedure proceeds to start points of each of the rotation speed steps, detection of whether the rotation speed of the drum or the electric motor reaches or remains stable at the corresponding rotation speed during preset times T1 to T5 is started, and it is determined whether to end the spin-drying procedure and whether to cancel the heat-drying procedure according to a detection result.
  • Another objective of the present invention is to provide a control method, so that the fabric processing device can instantly adjust the spin-drying procedure and/or the heat-drying procedure according to the operation conditions of the spin-drying procedure.
  • a method for controlling a spin-drying procedure and a heat-drying procedure of a fabric processing device includes: selecting and then starting to execute a spin-drying procedure and a subsequent heat-drying procedure, where in the spin-drying procedure, a detection device detects a rotation speed of a drum or an electric motor; and if the rotation speed fails to reach or remain stable at a first preset rotation speed S1 during a first preset time T1, the spin-drying procedure is ended, and the subsequent heat-drying procedure is cancelled.
  • the spin-drying procedure already completed accounts for less than 60% of an entire process of the spin-drying procedure.
  • the rotation speed of the drum or the electric motor reaches the first preset rotation speed S1 and maintains the first preset rotation speed S1 during the first set time T1
  • the rotation speed is then increased; if the detection device detects that the rotation speed of the drum or the electric motor fails to reach or remain stable at a second preset rotation speed S2 during a second preset time T2, the spin-drying procedure is ended and execution of the heat-drying procedure is directly started.
  • the spin-drying procedure when the spin-drying procedure is ended and execution of the heat-drying procedure is started, the spin-drying procedure already completed accounts for at least 60% of the entire process of the spin-drying procedure.
  • the spin-drying procedure includes a plurality of incremental rotation speed steps; on these rotation speed steps, the electric motor and the drum maintain a corresponding rotation speed during set times T1 to T5; when the spin-drying procedure proceeds to start points of each of the rotation speed steps, detection of whether the rotation speed of the drum or the electric motor reaches or remains stable at the corresponding rotation speed during preset times T1 to T5 is started, and it is determined whether to end the spin-drying procedure and whether to cancel the heat-drying procedure according to a detection result.
  • the fabric processing device can judge whether the spin-drying procedure is abnormal according to the rotation speed of the drum or the electric motor in the spin-drying procedure, and control the spin-drying procedure and/or the heat-drying procedure according to a detection result of the rotation speed, thereby avoiding heat-drying on fabrics with a high water content, saving energy and time, and simultaneously avoiding a heat-drying failure due to an excessive water content of fabrics.
  • a washer-dryer 1 includes a cabinet 2; a tub 3 is installed in the cabinet 2; a drum 5 driven by an electric motor 4 is rotatably installed in the tub 3, to accommodate fabrics to be washed and dried; the tub 3 is connected to an air circulation channel 6, where the air circulation channel 6 includes a condensation device 7 for condensing hot and humid air from the tub 3 and the drum 5, a heating device 8 for heating condensed air, and a blowing device 9 for enabling air to circulate in the air circulation channel 6 and the tub 3.
  • the air circulation channel 6 includes a condensation device 7 for condensing hot and humid air from the tub 3 and the drum 5, a heating device 8 for heating condensed air, and a blowing device 9 for enabling air to circulate in the air circulation channel 6 and the tub 3.
  • the washing machine 1 further includes a control device 10, for controlling operation of procedures; a display device 11, connected to the control device 10, for displaying information of various kinds of the washing machine 1 in characters, symbols and/or patterns; and a detection device 12, for detecting a rotation speed of the drum 5 or the electric motor 4.
  • a control device 10 for controlling operation of procedures
  • a display device 11 connected to the control device 10, for displaying information of various kinds of the washing machine 1 in characters, symbols and/or patterns
  • a detection device 12 for detecting a rotation speed of the drum 5 or the electric motor 4.
  • the washer-dryer 1 has a washing procedure and a heat-drying procedure, and the washing procedure and the heat-drying procedure may be both selected. After the washing procedure is ended, the heat-drying procedure automatically starts, where a last stage of the washing procedure includes an ultimate spin-drying procedure. The drum 5 rotates at a high speed in the ultimate spin-drying procedure to remove most of water out of fabrics.
  • FIG. 2 is a flowchart illustrating the ultimate spin-drying procedure and the heat-drying procedure after a user simultaneously selects the washing procedure and the heat-drying procedure.
  • FIG. 3 is a coordinate graph of rotation speeds and times in the ultimate spin-drying procedure. As shown in the figures, the spin-drying procedure includes a plurality of incremental rotation speed steps P1 to P5. After the ultimate spin-drying procedure starts, the rotation speed of the drum is gradually increased.
  • step 1 S1 is performed, where when the procedure proceeds to a point where the rotation speed of the drum is 450 rpm, that is, around a start point ST1 of a first rotation speed step P1, the detection device 12 judges the rotation speed of the drum; if the rotation speed of the drum fails to remain stable at 450 rpm during a first preset time T1, the control device 10 determines that the spin-drying procedure already completed accounts for 10% of an entire process of the spin-drying procedure, which is not suitable for heat-drying; therefore, the control device 10 ends the ultimate spin-drying procedure, cancels the subsequent heat-drying procedure, and then displays information indicating that 10% of the spin-drying procedure is completed on the display device 11.
  • step 2 S2 is performed, where when the procedure proceeds to a point where the rotation speed of the drum is 700 rpm, that is, around a start point ST2 of a second rotation speed step P2, the detection device 12 judges the rotation speed of the drum; if the rotation speed of the drum fails to remain stable at 700 rpm during a second preset time T2, the control device 10 determines that the spin-drying procedure already completed accounts for 25% of the entire process of the spin-drying procedure, which is not suitable for heat-drying; therefore, the control device 10 ends the ultimate spin-drying procedure, cancels the subsequent heat-drying procedure, and displays information indicating that 25% of the spin-drying procedure is completed on the display device 11.
  • step 3 S3 is performed, where when the procedure proceeds to a point where the rotation speed of the drum is 1000 rpm, that is, around a start point ST3 of a third rotation speed step P3, the detection device 12 judges the rotation speed of the drum; if the rotation speed of the drum fails to remain stable at 1000 rpm during a third preset time T3, the control device 10 determines that the spin-drying procedure already completed accounts for 45% of the entire process of the spin-drying procedure, which is not suitable for heat-drying; therefore, the control device 10 ends the ultimate spin-drying procedure, cancels the subsequent heat-drying procedure, and displays information indicating that 45% of the spin-drying procedure is completed on the display device 11.
  • step 4 S4 is performed, where when the procedure proceeds to a point where the rotation speed of the drum is 1200 rpm, that is, around a start point ST4 of a fourth rotation speed step P4, the detection device 12 judges the rotation speed of the drum; if the rotation speed of the drum fails to remain stable at 1200 rpm during a fourth preset time T4, the control device 10 determines that the spin-drying procedure already completed accounts for 60% of the entire process of the spin-drying procedure, which is suitable for heat-drying; therefore, the control device 10 ends the ultimate spin-drying procedure, directly starts the subsequent heat-drying procedure, and displays information indicating that 60% of the spin-drying procedure is completed on the display device 11.
  • step 5 S5 is performed, where when the procedure proceeds to a point where the rotation speed of the drum is 1500 rpm, that is, around a start point ST5 of a fifth rotation speed step P5, the detection device 12 judges the rotation speed of the drum; if the rotation speed of the drum fails to remain stable at 1500 rpm during a fifth preset time T5, the control device 10 determines that the spin-drying procedure already completed accounts for 90% of the entire process of the spin-drying procedure, which is suitable for heat-drying; therefore, the control device 10 ends the ultimate spin-drying procedure, directly starts the subsequent heat-drying procedure, and displays information indicating that 90% of the spin-drying procedure is completed on the display device 11.
  • the device 10 determines that the entire process of the spin-drying procedure is completed, displays information indicating that 100% of the spin-drying procedure is completed on the display device 11, and starts the subsequent heat-drying procedure simultaneously.
  • the preset times T1 to T5 for determining whether the rotation speed of the drum remains stable are the same. In other embodiments, the present times T1 to T5 may be different.
