摘要： PURPOSE:To judge the quantity of cloth precisely and to perform precise operation cycle control corresponding to the quantity of cloth even a large quantity of cloth exist by obtaining the accumulating total of voltage cycle time at every repeat of turning on/off of a motor, and detecting the quantity of cloth by adding prescribed time on the accumulating total when no voltage cycle time is detected when the motor is turned off. CONSTITUTION:In a cloth quantity detecting cycle, inversion stirring with on-time for 0.4sec and off-time for 1sec is performed, and the counter electromotive force of the motor 8 when a rotor 6 is rotated with inertia in off-time is detected with the terminal voltage of a capacitor 8a for motor 8 driving, and it is converted to a DC rectangular pulse, and the quantity of cloth is decided by measuring a time t1 between the pulses. Even when the measurement of the pulse time width t1 for even one time out of ten times is missed in the case of applying a load exceeding a certain level, it follows that a rank must be set at a large quantity load i.e., the same cloth quantity rank as that of a rated load. Therefore, a certain constant value is decided in advance when no pulse time width t1 is impossible to measure. The value is decided setting a measurable maximum cycle as reference. In such a way, it is possible to bracket the cloth quantity rank with especially capacitance in the neighborhood of rated capacitance.

摘要： PURPOSE:To obtain a rotary vane capable of sensing the volume of various kinds of clothes with high accuracy by changing the height of the main blade of the rotary vane to stir the cloth to be washed, and setting the height of an auxiliary small blade at the one relating to that of the main blade. CONSTITUTION:The rotary vane 6 is provided at a washing tub 5, and the rotary vane 6 is rotated when a washing process and a rinsing process are performed, and in a dehydrating process, it is rotated at high speed with the washing tub 5. The auxiliary small blade 51 is located between the main blades 50 and 52 of the rotary vane 6, and the height of the main blades 50 and 52 are set at H and (h), and that of the auxiliary small blade 51 at h2. The height H/h of the main blades 50 and 52 are set between 1.1 to 1.5, and sensing accuracy can be improved by setting H/h at >=1.1, and resistance received by the blade is increased and a mechanical force applied to wash is increased and the wash is impaired by setting H/h at >=1.5. When h2/h is set between 0.2-0.8 and h2/h less than 0.2, the mechanical force applied to the rotary vane is decreased since contact with the cloth is reduced, and also, when h2/h exceeds 0.8, the valley of the main blades 50 and 52 disappears, which lowers the mechanical force applied to the cloth.

摘要： PURPOSE:To reduce difference between the static torque and dynamic torque of a brake and to reduce a sliding tone as well when the brake is operated by changing the quality of a lining from synthetic resin to oil-containing colk and applying grease including molybdenum disulfide to the surface of the lining. CONSTITUTION:An attenuator is equipped with a groove part and the width of the groove is formed so as to be slightly smaller than the line diameter of a coil spring 105 and further to be matched with the shape of a hook part. A brake panel 114 is equipped with colk sheet-made linings 115 to be integral by adhesion, etc., on the both side of an outer periphery and bosses 116 are idly fitted in an idle fitting part 117. The brake panel 114 gets contact with a brake attenuator 118 and a lower case 121 with pressure by the brake attenuator 118, brake oscillator spring 119 and volt 120 for spring. Then, the surface of the lining 115 is engraved while including oil and further the grease including the molybdenum dislufide is applied further. The grease generates the stable brake torque and prevents a foreign tone such as a ringing tone, etc., when the lining 115 is slid.

摘要： PURPOSE:To transmit motive force to a brake mechanism without fail and to prevent energy from being accumulated by loosening a clutch spring by specifying difference between the outer diameter of the clutch spring and the inner diameter of a spring colar. CONSTITUTION:Since a clutch spring 128 is engaged with a hole 139 of a boss 124 to be rotated integrally with a washing and dehydrating tank 5, the clutch spring 128 is forcedly set in a direction, where the clutch spring is more loosened, and the energy is accumulated when the clutch spring tends to return. The return of the clutch spring is prevented by holding a spring color 130 with the frictional force of a manipulation band 137 provided in the outer peripheral part of the spring colar 130. However, the accumulated energy of the clutch spring 128 trues to return a clutch spring 129 to an original with the spring colar 130 against the frictional force of the manipulation band 137. Then, by suppressing the difference psid2-psid1 between an outer diameter psid1 of the clutch spring 128 and an inner diameter psid2 of the spring colar 130 less than 10% for the outer diameter psid1 of the clutch spring 128. Thus, the clutch spring 128 is prevented from spreading any more.

摘要： PURPOSE:To improve the collection efficiency of the title mechanism and the property of handling the mechanism and to prevent the adhesion of a waste thread to clothing by turnably providing a flowing out preventing wall extending from the upper edge to the lower edge of a filter cover and protruding in a direction toward the center of an inner tub for a place positioned at the middle of a front opening on the sidewall of a washing tube. CONSTITUTION:The mechanism has composition in which a waste thread flowing out preventing wall 35 is provided turnably for the place positioned at the middle of a filter case 31a of a parallel plane part 30 of a washing tube 11, and the wall 35 extends from the upper edge to the lower edge of a filter cover 36 and protrudes in the direction toward the center of the inner tube. For each of the upper edge part and the lower edge part of the backflow preventing wall 35, a fitting claw 35b inserted and fixed into a fitting hole 37b provided for the parallel plane part of the washing tube 11 is provided. Accordingly to this type of waste thread removing filter, the waste thread, waste cotton, etc., generated during washing and rinsing enter from several opening holes 32 provided for both side surfaces of the filter case 31a by the circulation of a water flow due to the rotation of a stirring blade 13 in the washing tub and are collected in a filter 33.

摘要： PURPOSE:To start a washing process, reset a main shaft automatically at the time of a cycle end so as to prepare for the next washing as well as to make fully automatic operation performable every time with simple operation by structuring a machine to have a main switch turned to ON only when a control knob is pressed and the main shaft is thrust in. CONSTITUTION:A main switch 52 is turned on by pressing a control knob 54 and a main shaft 53 is thrust in, and thus washing is started. At this time, vertical motion of the main shaft 53 is locked. Next, if a washing cycle is over, the lock of the main shaft 53 is released by an integral separate cam 56 installed in a main cam 50, and the main shaft 53 is automatically reset to the original position, while the main switch 52 is turned off. At the time of next operation, the main cam 50 is rotated up to a position starting operating action by pushing the timer main shaft 53. Doing like this, automatic operation can be done every time by only pushing the control knob 54.
