全散音を低減させる。<Means for Solving the Problems> The means for solving the problems according to the present invention, as shown in FIGS. 1 to 7, perform the washing process, rinsing process,
In a washing machine that automatically executes a washing process including a dehydration process, a normal washing means 1 for carrying out a normal washing process;
A silent washing means 2 for executing a silent washing process with less noise than a normal washing process, and a selection means 32 for selecting between the normal washing process and the silent washing process are provided.6 <Operation> In the above problem solving means When washing at a time when the surroundings are quiet, such as at night or early in the morning, if the silent washing process is selected, water is first supplied and the washing process is executed. At this time, as shown in FIG. 5, the silent washing means 2 changes the rotation time of the stirring blade 3 to 2.0 seconds and the stop time of 0.8 seconds in the normal washing process. 1
．． Shorten the time to 0 seconds to weaken the force of the water flow and set the stop time to 2.
It is set to 4 seconds, three times the normal time, and reduces the sound of water flow and all noises when reversing.
しかしながら、水流が弱くなることは洗浄性能に影響を
及ぼすため、洗い工程の時間を２０分にして通常の１０

時の振動音や水の振り切り音等を抑制する。Next, when the washing process is completed, drainage is performed and the dehydration process is started. In the normal washing process, the rotation speed of the dehydration tank 4 is 900 rpm, but the rotation speed is controlled by the silent washing means 2 to be 720 to 780 rpm. At this time, the time of the dehydration process is set to twice the length of the normal process to compensate for the decrease in dehydration ability. In this way, vibration noise during dehydration, water shaking noise, etc. are suppressed.

い。When doing laundry when the surrounding area is quiet, such as at night or early in the morning,
First, load the laundry, turn on the power switch 20,
When the silent washing process is selected with the selection switch of the key switch group 25, the washing process is started. Note that when noise is not a problem, such as during the daytime, the normal washing process may be selected.
運転が開始されると、給水が行なわれ洗い工程が実行さ

回転時間を１．０秒と短くして、水流の勢いを弱め、停
止時間を２．４秒と通常の３倍に設定されており、反転
時の水流音や全散音を低減させる。When operation is started, water is supplied and a washing process is performed. At this time, as shown in FIG. 5, the silent washing means 2, in the normal washing process, the rotation time of the stirring blade 3 is set to 2.0 seconds and the stop time is set to 0.8 seconds.
The rotation time is shortened to 1.0 seconds to weaken the force of the water flow, and the stopping time is set to 2.4 seconds, three times the normal time, reducing water flow noise and overall noise during reversal.
しかしながら、水流が弱くなることは洗浄性能に影響を
及ぼすため、洗い工程の時間を２０分にして通常の１０

ている。However, the weakening of the water flow affects the cleaning performance, so the washing process time is changed from 20 minutes to the usual 10 minutes.
setting to maintain cleaning performance as usual by increasing the cleaning performance to twice that of 10 minutes. The cleaning performance is determined by the cleaning ability of the detergent itself as well as the mechanical force generated by the stirring blade 3.Although the water flow in this example is weak, the total mechanical force of the washing process is compensated for by extending the time. I have to.

。Next, when the washing process is completed, drainage is performed and the dehydration process is started. In the normal washing process, the rotation speed of the dehydration tank 4 is 900 rpm, but the rotation speed is controlled by the silent washing means 2 to be 720 to 780 rpm. At this time, the rotation speed of the dehydration tank 4 is detected by the rotation speed sensor 24, and if it becomes 7BOrpm or more, the motor drive unit 13a
The relay 18 is turned off to reduce the torque of the motor 13 so that the rotational speed of the dehydration tank 4 does not exceed 780 rH+. If necessary, intermittent operation is performed in this state, and the rotation speed is controlled to be maintained at 720 to 780 rpm. If the number of revolutions falls below 72 rpm, the relay 18 is turned on and the capacitor 19 is connected to the motor 13 to increase the torque and provide feedback to maintain the number of revolutions at a predetermined value.
しかし、回転数を低目に保つことにより当然の結果とし

る。However, keeping the rotational speed low naturally leads to a decrease in dewatering capacity, but as a countermeasure, the dehydration process time is set to twice the normal process time to compensate for the decrease in dewatering capacity. If necessary, as shown in Figure 6, the rotation speed of the dehydration tank 4 can be increased to the normal 900 for a short period of time (about 1 minute).
Dehydration may be carried out at rpm. In this way, vibration noise during dehydration, water shaking noise, etc. are suppressed.
そして、脱水工程が終了すると、すすぎ工程が実行され
、再び排水、脱水が行なわ九、これらの工程を二回繰り
返すことによって洗濯工程が完了する。そうすると、ブ
ザー１７が洗濯終了の報知音を鳴動する。When the dewatering process is completed, a rinsing process is performed, and draining and dewatering are performed again, and these processes are repeated twice to complete the washing process. Then, the buzzer 17 sounds a tone indicating the end of washing.

することができる。Therefore, by providing the silent washing means 2, the noise value is reduced by about 2 to 4 dB during the washing and dehydration process compared to the normal washing process, so you can operate quietly at night or early in the morning without worrying about surrounding houses, etc. It can be implemented in any way. However, it will take longer to run, but if you use the reservation switch, you can set the time to finish washing, so you don't have to worry about the time. In addition, cleaning and dehydration capabilities, etc. can be maintained as usual.
