Problems solved by technology

This is because, although the braking operation is performed immediately by cutting off the power supply, the brake is released before the rotation of the washing tub stops due to the power supply being turned on again.
In this way, although it is an operation that is not normally performed, in order to prevent the rotation of the washing tub from not stopping, the braking operation is performed for a predetermined time even when the washing tub is not rotating when the power is turned on.
Therefore, there is a problem that the user cannot simply turn the washing tub until the prescribed time elapses.

[0021] figure 1 It is a side cross-sectional view of the washing machine according to the first embodiment of the present invention. Such as figure 1 As shown, the outer frame 1 of the washing machine utilizes the suspension rod 2 to suspend the sink 3 . A washing and dehydrating tank 4 (hereinafter referred to as washing tank 4 ) serving both as a washing tank and a dehydrating tank is installed inside the water tank 3 so as to be spin-drying. The pulsator 5 is rotatably arranged at the bottom of the washing tub 4 . The lower blade 6 is provided integrally with the pulsator 5 . Motor 7 is a drive unit that drives pulsator 5 or washing tub 4 via V-belt 8 and reduction mechanism 9 .

[0022] The circulating water channel 10 for lint and the circulating water channel 11 for sprinkler nozzles extend from the pump chamber 12 on the outer periphery of the lower blade 6 of the pulsator 5 to the upper part of the washing tub 4 . A detachable lint filter 13 is provided on the u...

Abstract

A washing machine includes a washing tub (4), a pulsator (5), a motor (7), a braking mechanism, and a control device (50). The washing tank (4) is capable of spinning for dehydration. The pulsator (5) is rotatably arranged on the inner bottom of the washing tank (4). The electric motor (7) drives the washing tank (4) and the pulsator (5). The braking mechanism applies a braking force to the rotation of the washing tank (4). A control device (50) executes a series of washing operations such as a washing step, a rinsing step, and a dehydration step, and has a control unit and a storage unit. The control unit controls a series of processes, and detects whether the operation based on the setting content input by the user is completed after the operation is completely executed or completed in the middle of the operation. The storage unit stores the completion state of the previous washing operation. In addition, the control unit changes the control of the braking mechanism according to the end state of the previous washing operation stored in the storage unit.

Description

technical field [0001] The present invention relates to a washing machine having a braking mechanism for applying a braking force to the rotation of a washing and dehydrating tank. Background technique [0002] With regard to the conventional washing machine, in the state where the power is not turned on or only the power is turned on, in order to ensure safety, the brake mechanism is used to always apply a braking force to the rotation of the washing and dehydrating tank, so that it is difficult to make the washing and dehydration tank be operated by human power. The status of dehydration tank rotation. Therefore, the following technology has been disclosed: after a predetermined time has elapsed since the power is turned on, the brake release device is operated to perform the brake release process so that the washing and dehydration tank can be manually rotated (for example, refer to Patent Literature 1). [0003] Figure 6 It is a side sectional view of a conventional w...
