TH44400A - Drive device of the washing machine - Google Patents

Abstract

DC60 (19/07/43) Washing machine drive unit designed for ease of use compared to conventional twin-tub washing machines, resulting in a smaller washing machine size for improved transport and installation, and reducing the number of electronic components compared to conventional automatic washing machines, thus minimizing inconsistencies and manufacturing costs. The washing machine drive unit consists of a washing machine with a spin-drying tub installed inside the outer tub, a pulsating unit mounted on the surface of the spin-drying tub, and a power transmission unit for transmitting the motor's drive force to the spin-drying tub and the pulsating unit. The unit comprises: a switch for selecting the washing or draining mode; a drainage unit and a brake unit for closing the outer tub's drainage and braking the spin-drying tub when the washing mode is selected by the switch, and for opening the outer tub's drainage and releasing the brake of the spin-drying tub when the drainage mode is selected by the switch; and a motor drive unit for power acquisition. Power is supplied via switches and time controls. The first time control selects the washing mode for washing time and water flow, the second time control selects the spin-drying time, and a switch drives the motor according to the washing time and water flow selected by the first time control for the washing operation. Power is also supplied via the second switch and time control when the draining mode is selected. The washing machine's drive system is designed for ease of use compared to conventional twin-tub washing machines, resulting in a smaller size for easier transport and installation, and a reduction in the number of electronic components compared to conventional automatic washing machines. This minimizes inconsistencies and manufacturing costs. The washing machine's drive system includes a washing machine with a spin-drying drum integrated into the washing unit, a pulsating device mounted on the surface of the spin-drying drum, and a power transmission device for motor drive. To the spin dryer, combined with washing and pulsating motion, the device consists of: a switch for selecting the washing or draining mode; a drain unit and a brake unit for shutting off the outer drum drain and braking the spin dryer in conjunction with washing when the washing mode is selected by the switch, and for opening the outer drum drain and releasing the spin dryer brake in conjunction with washing when the draining mode is selected by the switch; and a motor drive unit for receiving power via the first switch and timer when the washing mode is selected by the first timer for selecting the washing time and water flow, the second timer for selecting the spin drying time, and a switch to drive the motor according to the washing time and water flow selected by the first timer for the washing operation, and for receiving power via the second switch and timer when the draining mode is selected by the switch to drive the motor during the spin drying operation selected by the second timer.

Claims (9)

1. The driving components of a washing machine, including a washing machine with a spin-dryer integrated into the washing and spin-drying drum, consist of: a mode selection switch (washing or draining mode); a drain and stop device for shutting off the outer drum drain and stopping the spin-dryer when the washing mode is selected, and for opening the outer drum drain and releasing the spin-dryer stop when the draining mode is selected; a first timer for selecting the washing time and water flow; a second timer for selecting the spin-drying time; and a motor drive unit that receives power via the switches and the first timer, and drives the motor according to the set washing time and water flow when the washing mode is selected. The first timer controls the washing operation and post-washing cycle via a switch, and the second timer, when the drain mode is selected by the switch, drives the motor during the spin-drying process, as set by the second timer. 2. The device referred to in claim 1 also includes a door switch for cutting off the power supply to the drain and braking device and a second timer control when the washing machine door is opened. 3. The device as described in claim 2, which includes the drain and braking device, consists of: a mode selection knob for user control to select a specific washing or draining mode; a cam for connection to the mode deactivation knob; a drain valve for opening and closing the drain outlet, mounted on the outer drum; and a cover latch cable, with both ends connected to the cam and drain valve to close the drain valve when the mode selection knob is turned to the washing mode side and to open the drain valve when the mode selection knob is turned to the drain mode side. 4. The device as specified in claim 3, where the cover latch cable is supported in the washing machine body and outer drum by angled supports (theta) at both ends as specified. 5. Cable of the cover latch as specified in claim 4 where the specified angle (theta) is greater than 90 degrees. 6. The drainage and braking devices as specified in claim number 3, where the cover latch cable consists of: a core cable that moves along the roller when rotated; a spring mounted around the core cable; and covers for enclosing the spring at both ends. 7. The cover latch cable, as specified in either claim 3 or 6, also includes a fixed rod installed at the door for holding the cam in place when the mode selection dial is rotated to the drain mode side while the door is closed, maintaining the mode selection dial in the selected drain mode. 8. The fixed rod, as specified in claim number 7, separates from the cam when the door is opened, causing the mode selection dial to be rotated to the washing mode side. 9. The device as specified in Claim 1, where the drain and braking device consists of: a solenoid coil for receiving power via the switch and gate switch for operation; a brake lever for being actuated by the solenoid coil to brake or release the spin dryer drum in conjunction with the washing; a connecting lever for being connected to the brake lever; and a drain valve for being actuated by the connecting lever to open and close the drain outlet at the outside drum.
