Definitions

  • the washing machine described in the following Patent Document 1 includes: a washing and dehydration tub, in which a pulsator is rotatably arranged at its inner bottom; a receiving bucket, which rotatably encloses the washing and dehydration barrel; The dewatering barrel is rotated and driven; and the control unit controls the cleaning process and rinsing process.
  • the control unit performs the stirring process and the washing tub rotation process during the cleaning process and the rinsing process.
  • the control unit drives the pulsator in reverse.
  • the control unit drives the rotation of the washing and dehydration tub to increase the washing water between the washing and dehydration tub and the water receiving tub, and sprinkle water into the washing and dehydration tub from above.
  • the laundry when the washing tub rotation process is performed with a large amount of laundry in the washing and dehydration tub, the laundry will rise along the inner circumference of the washing and dehydration tub with the high-speed rotation of the washing and dehydration tub, and partially washed I am afraid that the material will emerge from the entrance and exit at the upper end of the washing and dehydrating barrel.
  • the emerging laundry may be soiled or damaged due to friction by members around the entrance and exit during the dehydration process.
  • the rotary wing rotates to spread the laundry in the washing tub.
  • the laundry in the washing tub can be sinked away from the entrance and exit. Therefore, even in a state where the laundry in the washing tub is approaching the inlet and outlet during the tub rotation processing, the emergence of the laundry from the inlet and outlet to the outside of the washing tub can be suppressed by the emergence suppression treatment immediately after the tub rotation processing.
  • the emission suppression treatment a part of the water in the outer tub is discharged on the eve of the rotation of the washing tub in the tub rotation processing, and therefore, the water level in the washing tub decreases.
  • the laundry in the washing tub can be lowered and moved away from the inlet and outlet in the state on the eve of the start of rotation of the washing tub in the tub rotation processing. Therefore, it is possible to prevent the laundry from coming out of the washing tub from the inlet and outlet due to the subsequent rotation of the washing tub.
  • Fig. 2 is a block diagram showing the electrical structure of the vertical washing machine.
  • Fig. 6 is a flowchart showing the barrel rotation processing of the second embodiment.
  • the washing tub 4 is made of metal, for example, and is formed in a cylindrical shape with a bottom that is slightly smaller than the outer tub 3, and can store laundry Q inside.
  • the washing tub 4 is coaxially arranged in the outer tub 3.
  • the washing tub 4 in the state housed in the outer tub 3 can be rotated around an axis J that constitutes its central axis and extends in the vertical direction Z.
  • the washing tub 4 has: an approximately cylindrical circumferential wall 4A arranged in the vertical direction Z, a bottom wall 4B that blocks the hollow portion of the circumferential wall 4A from the lower side Z2, and a protruding portion along the upper edge of the circumferential wall 4A toward the axis J Annular annular wall 4C.
  • the pulsator 5 is formed in a disk shape centered on the axis J, and is arranged on the bottom wall 4B in the washing tub 4.
  • the upper surface of the pulsator 5 facing the inlet and outlet 4D of the washing tub 4 is provided with a plurality of blades 5A arranged radially.
  • the pulsator 5 is provided with a rotating shaft 18 extending from its center along the axis J to the lower side Z2.
  • the rotating shaft 18 is inserted into the hollow portion of the support shaft 17, and the lower end of the rotating shaft 18 is located on the lower side Z2 of the bottom wall 3B of the outer tub 3.
  • the rotation speed reading device 27 functions as an example of a detection unit.
  • the rotation speed reading device 27 is a device that reads the rotation speed of the motor 6, strictly speaking, the rotation speed of the output shaft 19 of the motor 6, and is constituted by, for example, a Hall IC.
  • the rotation speed read by the rotation speed reading device 27 is input to the microcomputer 21 in real time.
  • the microcomputer 21 controls the duty ratio of the voltage applied to the motor 6 based on the input rotation speed, thereby controlling the motor 6 to rotate at a desired rotation speed.
  • the respective rotation speeds of the washing tub 4 and the pulsator 5 may be the same as the rotation speed of the motor 6 or may be a value obtained by multiplying a predetermined constant such as the reduction ratio of the clutch 7 and the rotation speed of the motor 6.
  • the microcomputer 21 detects the load amount of the laundry Q containing water in the washing tub 4 by the water supply process during the stirring process.
  • the microcomputer 21 rotates the pulsator 5 carrying the laundry Q for a predetermined period of time, then stops the driving of the motor 6 and causes the motor 6 to inertially rotate, which is read by the rotation speed reading device 27 Calculate the inertial rotation amount of the motor 6 at this time using a known method.
  • the inertial rotation amount of the motor 6 is an index indicating the amount of load. The larger the load, the smaller the amount of inertia rotation of the motor 6 connected to the pulsator 5 carrying heavier laundry Q.
  • the rising water passes through between the ribs 3G arranged on the lower surface of the annular wall 3C of the outer tub 3 and falls while spirally turning, and pours into the washing tub 4 from the inlet and outlet 4D of the washing tub 4 (refer to FIG. 1 and the thick double-dot chain line in Figure 5).
  • the guide surface 3E of the annular wall 3C of the outer tub 3 guides the water passing between the ribs 3G downward toward the inlet and outlet 4D (refer to FIG. 1).
  • the tub rotation process may be performed only when the amount of laundry Q is larger than a predetermined amount of washing.
  • step S55 When the microcomputer 21 detects a bias of a predetermined magnitude or more in the barrel rotation processing ("Yes" in step S55), it confirms whether the bias measurement is the first bias measurement in the barrel rotation processing (step S55). S58). The number of detections of the bias in the barrel rotation process this time is temporarily stored in the memory 23.
  • the emission suppression processing when the load amount of the laundry Q is greater than or equal to the predetermined value, both before and after the rotation of the washing tub 4 in the tub rotation processing (step S5), the emission suppression processing is performed, but the emission The suppression process may be executed at least at any one of the timing before and after the rotation of the washing tub 4 in the tub rotation processing (step S5).
  • the emission suppression processing is performed before and after the rotation of the washing tub 4 in the tub rotation processing (step S5) of the washing process, but the emission suppression processing may also be performed during the tub rotation of the second rinsing process. At least one of before and after the rotation of the washing tub 4 in the processing (step S12) may be executed.
  • the content of the barrel rotation process (step S5) in the washing process is one of the first embodiment and the second embodiment, and the barrel rotation process (step S12) in the second rinsing process
  • the content is the other of the first embodiment and the second embodiment.
