Description of the Related Art In a general automatic washing machine, rinsing after washing is usually performed a plurality of times, for example, twice, and at the beginning, so-called water rinsing is performed in which water supply is continued even after supplying a predetermined amount of water. In the second time, so-called rinsing is performed so that the water supply is stopped after supplying a predetermined amount of water. For this reason, in rinsing, the softening agent is put into the washing / dehydrating tank and the softening agent treatment of the laundry is performed.

る。Recently, as a water-saving fully automatic washing machine, in order to suppress the amount of water used during rinsing as much as possible,
The first rinse has been commercialized as a dehydrated rinse instead of a water-filled rinse. In this dehydration rinse, water is supplied to the washing / dehydrating tub so that the water soaks into the entire laundry, and if soaked, the water supply is stopped and the washing / dehydrating tub is rotated at high speed to perform dehydration. Rinsing is carried out with the water. Further, in this dehydration rinsing, the water needs to be supplied only to such an extent that the water soaks into the laundry, the amount of water used can be suppressed, and water can be saved.

5 starts the operation, and first executes the washing process. In this washing process, the control unit 15 supplies water by opening the water supply valve 9 until the water level sensor 13 detects a predetermined water level (until a predetermined amount of water is accumulated in the washing / dehydrating tank 5) ( S1 step). When a predetermined water level is detected, the water supply valve 9
Is closed. Then, when a predetermined amount of water is accumulated, the control unit 15 rotates only the rotary blades 6 at a low speed under the drive of the drive motor 7, thereby washing is performed (step S2).

In the dewatering and rinsing step, first, the drain valve 11 is opened to drain the washing water at the time of washing, and the washing and dewatering tub 5 is rotated at high speed together with the rotary vanes 6 to dewater the laundry (step S3). When this is finished, dehydration rinsing is executed (S4 step). The drain valve 11 maintains the open state.

濯兼脱水槽5はゆっくり回転する。That is, referring to FIG. 6, for a certain time t, the controller 15 opens the water supply valve 9 to supply water. During this water supply, the control unit 15 repeats driving the driving motor 7 for 1 second and stopping for 5 seconds. At this time, washing and dewatering tank 5
Repeats to enter the inertial rotation state immediately when it tries to rise to the high-speed rotation state together with the rotor blades 6. After all, the washing and dehydrating tub 5 rotates slowly.

み、洗濯物は水を十分含んだ状態となる。Therefore, water is supplied while the washing / dehydrating tub 5 slowly rotates, and the laundry in the washing / dehydrating tub 5 is almost evenly flooded with water, so that the entire laundry is impregnated with water. When the time t has elapsed, the water is sufficiently soaked in, and the laundry is in a state of containing a sufficient amount of water.

よりためすすぎが行われる(S6ステップ)。When the dehydration rinsing step is completed, the control section 15 subsequently executes a normal rinsing (reserving rinsing) step. In this process, as in the case of the washing process, the control unit 15 opens the water supply valve 9 to supply water until the water level sensor 13 detects a predetermined water level (S5 step).
The drain valve 11 is closed in advance just before the dehydration rinsing process. When the predetermined water level is detected, the water supply valve 9 is closed.
Then, when a predetermined amount of water is accumulated, the control unit 15 rotates only the rotary blades 6 under the drive of the drive motor 7, whereby the rinsing is performed (step S6).

脱水工程の終了により運転終了となる。When the normal rinsing process is completed, the control unit 15 finally executes the dehydration process. In the dehydration process, first, the drain valve 11 is opened to drain the water for rinsing (S7 step). When drainage is completed, control unit 1
In step 5, the washing / dehydrating tub 5 is rotated at high speed to perform dehydration (step S8). The drain valve 11 maintains the open state.
The operation ends when the dehydration process ends.

Kg以上である。中の場合は、2.5Kg以上3.5K
g未満である。小の場合は、2.5Kg未満である。In step S2 of the washing process, the control unit 15 also performs control along the flow of the program shown in FIG. That is, the control unit 15 inputs the drive motor current value at the time of washing detected by the load detection circuit 17 (step A1), compares this current value with a predetermined reference value, and based on the magnitude thereof. Perform load detection.
Specifically, the amount of laundry is classified into large, medium, and small to determine (A2 step). Larger amount of laundry is 3.5
It is Kg or more. In case of medium, 2.5Kg or more 3.5K
It is less than g. In the case of small, it is less than 2.5 Kg.

要時間t1を変化させるようにしても良い。Then, the control unit 15 changes the time required for one cycle consisting of water supply and dehydration, which is one of the setting conditions for the dehydration rinse, depending on whether the amount of laundry is large, medium or small. Specifically, it is changed to 5 minutes, 4 minutes, and 3 minutes (A3, A4, A5 steps). Instead of the required time for one cycle, the required time t for water supply during one cycle or the required time t1 for dehydration during one cycle may be changed depending on whether the laundry amount is large, medium or small.

なると云う特性に基づいたものである。Next, the control section 15 inputs a sampling of several drive motor current values at the time of washing detected by the load detection circuit 17 (step A6), and the degree of variation in the sampled current values (current value). The difference between the maximum value and the minimum value is obtained, and the degree of variation is compared with a predetermined reference value, and further load detection, that is, the quality of the laundry is detected based on the magnitude. Specifically, when the degree of variation is larger than the reference value, it is determined that the quality of the laundry is cotton, and when it is the other way around, it is determined that the quality of the laundry is synthetic fiber (A7 step). . This is based on the characteristic that the variation degree is large for cotton and the variation degree is small for synthetic fiber.

基づいて変化することになる。Then, the control unit 15 changes the number of repetitions of the cycle of water supply and dehydration, which is one of the set conditions for the dehydration rinse, depending on the quality of the laundry, that is, cotton or synthetic fiber. Specifically, in the case of cotton, the number of repetitions is changed to 3 times, and in the case of synthetic fiber, the number of repetitions is changed to 2 times (steps A8 and A9). Instead of the number of times the cycle is repeated, the required time for one cycle, the required time t for water supply during one cycle, and the required time t1 for dehydration during one cycle are changed according to the quality of the laundry. Is also good. In this case, each required time will change based on both the quantity and quality of the laundry.
