かけるようにしていた。2. Description of the Related Art A conventional fully automatic washing machine is shown in FIGS.
As shown in, the washing / dehydrating tub 1 has a pulsator 2 rotatably arranged at the center bottom. The aquarium 3 is a washing and dehydrating tub 1.
And the substrate 4 is fixed to the outer bottom of the water tank 3,
A washing / dehydration switching mechanism 7 having a drive motor 5, a drain valve 6 and a brake installed therein is disposed, and the outer edge of the substrate 4 is provided with an anti-vibration device 8 and a suspension rod 9 at an upper corner of an outer frame 10. Supports hanging from the corner. An upper cover 11 is provided on the upper part of the outer frame 10,
A water supply valve 12, a power switch 13, a control device 14, etc. are arranged. The control device 14 includes a signal control means 15 including a microcomputer, an operation display means 17 including a key switch and a display device stored in the operation panel 16, and a motor 5 and a drain valve 6 according to signals from the signal control means 15. A signal from the safety switch 19 and a signal from the rotation detecting means 20 for detecting the number of rotations of the motor 5 are input to the power switching means 18 for controlling the water supply valve 12 and the like and the signal control means 15. .. 21 is an AC power source, 22
Is a phase advancing capacitor of the motor 5. Signal control means 15
Turns on the drain valve 6 in the first drainage state in the dehydration process
In this state, the water in the washing / dehydrating tank 1 is drained, and the motor 5 is turned on after the drainage is completed. After that, the motor 5 is turned on and off at intervals of several seconds for intermittent operation to gradually drain water from the clothes. In this case, the rotation speed of the motor 5 is detected by the rotation detection means 20 each time and input to the signal control means 15. After that, the motor 5 is kept in the ON state to continuously dehydrate the clothes, and after the clothes are dehydrated, only the motor 5 is turned OFF, and the washing / dehydrating tub 1 is inertially operated. 6 is turned off and the brake is applied to end the dehydration process. Generally, in a fully automatic washing machine, the clothes are washed, drained, and then moved to the dehydration process. At this time, the clothes are rarely evenly distributed in the washing / dehydrating tub 1, and a non-uniform distribution is formed. As a result, the clothes are dehydrated, and the unevenness of the clothes causes an unbalance of the rotating object and causes vibration. A structure supported by a vibration-proof system such as the suspension rod 9 and the vibration-damping device 8 is called a vibration system, and a natural frequency is an inevitable component of the vibration system and the vibration-proof system. If the unbalance of the cloth during dehydration is large and the frequency generated in the vibration system matches the natural frequency, the amplitude of the vibration system becomes extremely large, for example, jumps up and down, It is in a state called a normal resonance point where it collides with the outer frame 10 or causes the rotary shaft to be damaged at a critical speed. In order to prevent such a phenomenon, when the amplitude of the vibration system is abnormally large, the safety switch 19 turns off the power supply to the motor 5 and the drain valve 6 to the washing / dehydrating tub 1 as shown in the stroke diagram of FIG. The driving force is released and the brake is applied immediately to the washing and dehydration tub 1
Was stopped so that there was no danger. However, when the safety switch 19 is operated as described above to release the driving force to the washing / dehydrating tub 1 and the brake is immediately applied to stop the washing / dehydrating tub 1, safety is ensured. However, since the vibration system collides with the outer frame 10, causing collision noise and movement of the outer frame 10, as shown in the stroke diagram of FIG. Is stopped, and after the delay time t has passed, the drain valve 6 is stopped from being powered so that the driving force to the washing / dehydrating tub 1 is released, and the brake is applied after a while after inertial rotation.

After a high speed inertial rotation for a while, it slows down and stops in the brake operation range B 1 , and it is a very dangerous state until it stops, and there is a problem that there is a risk of accidentally getting your hands caught. It was In view of the above problems, the present invention eliminates the collision of the vibration system with the main body and the movement of the main body when the safety switch is activated due to the unbalance of the clothes, and the safety after the safety switch is operated. The purpose is to provide a fully automatic washing machine to secure.

いる。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of a fully automatic washing machine according to an embodiment of the present invention is the same as that of the conventional example shown in FIGS. Figure 1
Shows the relationship between the time in the dehydration process and the dehydration rotation speed in one embodiment of the present invention. The operation of this embodiment will be described with reference to FIGS. 1, 2 and 3. The same parts as those in the conventional example are indicated by the same numbers, and the description thereof will be omitted. In the present embodiment, a signal is input to the signal control means 15 when the safety switch 19 is actuated due to an imbalance of clothes during the dehydration process, and the signal from the signal control means 15 immediately turns off the motor 5. Then, the washing / dehydrating tub 1 is inertially operated. Then, after the delay time t has elapsed, the drain valve 6 is turned off and the brake is applied. This delay time t
Is set to such a time that the vibration system does not collide with the outer frame 10 due to the reaction when the rotation speed of the washing / dehydrating tub 1 is decelerated and the brake is suddenly stopped, for example, about 2 seconds. However, the delay time t is equal to the vibration resonance point of the washing / dehydrating tank 1 when the motor 5 is turned on and the rotation speed V 1 is the same.
It is set within a predetermined time T A until it reaches. Therefore, the rotation speed V is equivalent to the vibration resonance point of the washing / dehydrating tank 1 and the like.
By the time it reaches 1, the rotation speed of the washing / dehydrating tub 1 has not reached the high-speed rotation range, and even if the lid of the fully automatic washing machine is opened, the washing / dehydrating tub 1 does not exert much inertial force. Therefore, even if the delay time t is provided, the inertial rotation does not occur and the vehicle can be stopped immediately. On the contrary, at the number of rotations exceeding the vibration resonance point of the washing / dehydrating tank 1 or the like, for example, at the time of continuous dehydration operation after intermittent dehydration, since the delay time t is not provided, the safety switch is operated at point a of continuous dehydration. When 19 is activated, signal control means
Signal immediately while the OFF state of the motor 5 at from 15, the drain valve 6 is turned OFF braked by brake operation range B 1, and is adapted to stop the washing and dewatering tank 1.

And a rotation detection means for detecting the number of rotations of the motor, and a signal control means composed of a microcomputer, the signal control means driving the washing / dehydrating tub when the safety switch is activated. The motor is immediately turned off, and after the delay time t has elapsed, the brake is operated and the motor is turned on to reach the rotational speed V 1 equivalent to the vibration resonance point of the washing / dehydrating tank. By setting the delay time t within the predetermined time T A until the safety switch is activated, the washing / dehydrating tub is allowed to coast for a while. Since the brake is applied at a place where the kinetic energy becomes small, the energy consumed by the brake can be small, and therefore the washing / dehydration switching mechanism (which has the brake mechanism) provided in the vibration system can be changed to the vibration system. The reaction force of is reduced, the vibration of the vibration system due to the force is small, and collision and movement to the outer frame are eliminated. Further, the delay time t is set within a predetermined time T A until the rotation speed V 1 equivalent to the vibration resonance point of the washing / dehydrating tub or the like is reached, so that the washing / dehydrating tub rotates at high speed. Even if the lid of the fully automatic washing machine is opened immediately after the safety switch has been actuated since the rotation range has not been reached, there is not so much inertial force acting on the washing / dehydrating tub, so there is no inertial rotation and the machine immediately stops. There is no danger of accidentally getting your hands caught, and it is possible to bring about a great effect that it is safe and can be stopped without abnormality even when the unbalance of clothes is large.
