率良くはできないという問題点を有していた。[Problems to be Solved by the Invention] In the above-mentioned case, drainage is performed before intermediate dewatering. However, if drainage conditions are not good, for example, if the drainage hose is long, or if the water pipes in the house that the drainage hose faces are narrow or clogged, the drainage may not be completed within the specified time. The next intermediate dewatering process will begin with water remaining in the machine. In this case, the tank is rotated underwater, and the rotation speed does not increase easily due to the resistance. For this reason, in intermediate dehydration, which is set for a short time just to squeeze out the detergent from the laundry, the rotation of the tank does not reach a sufficient speed and the detergent cannot be squeezed out sufficiently. However, there was a problem that rinsing could not be performed efficiently.

The device is designed to perform water drainage, and includes a measuring means for measuring the drainage time during drainage before the intermediate dehydration, and a comparison means for comparing the measurement result with a predetermined time, and according to the comparison result, the drainage time is determined. The present invention is characterized in that it includes a control means for controlling execution of subsequent intermediate dehydration for a longer time than the standard time when it is determined that the time is longer than a predetermined time.

As the time is extended, the detergent is squeezed out for a longer time, and as a result, the detergent can be squeezed out sufficiently.

【実施例】以下、本発明の一実施例につき、図面を参照

The outer tank 2 is provided with a drive mechanism 4 mainly including a motor 3, a drain valve 5, etc. in its outer lower part, and an inner tank 7 having a large number of dewatering holes 6 is provided inside. . Furthermore, an agitator 8 is disposed at the bottom of the inner tank 7, and the agitator 8 is rotated forward and backward during washing by the drive mechanism 4, and the inner tank 7 is rotated by the same drive mechanism 4 during dewatering. It rotates at high speed in one direction.

になっている。On the other hand, a top cover 9 is provided on the upper surface of the outer box 1.
For example, a microcomputer 10 shown in FIG. 3 is disposed inside the front part of this. As will be described in detail later, this microcomputer 10 functions as a measuring means, a comparing means, and a controlling means, and receives switch signals from a switch input section 11 consisting of various switches. A detected water level signal is input from a water level sensor 12 provided to detect the water level stored in the outer tank 2 (inner tank 7). Based on these inputs and the control program stored in advance, the microcomputer 1
0 is a display section 13 consisting of various LEDs, etc., and the inner tank 7.
Each drive control signal is given to drive circuits 15 to 18 that respectively drive a water supply valve 14 provided to supply water into the (outer tank 2), a motor 3 of the drive mechanism 4, and a drain valve 5. There is.
【００１０】そこで、以下には、マイクロコンピュータ

The dehydration is progressed in the order in which the water is drained, and the water is drained just before each intermediate dehydration (
(not shown in Figure 4).

さで行なう（ステップＳ５）。FIG. 1 shows a control routine during drainage immediately before intermediate dehydration after washing, and when washing is completed (step S1), the microcomputer 10 starts the next drainage and at the same time controls the drainage time. Measurement is started (step S2). After that, the measured drainage time t
is compared with a predetermined time t1 (a time determined to be longer than normal drainage, although it is not abnormal), and it is determined whether the drainage time t is less than or equal to the predetermined time t1 (step S3). , as long as it is determined that the time is less than the predetermined time t1, it is next determined whether or not the drainage has been completed based on the water level detection signal from the water level sensor 12 (step S4), and the water level is continued until it is determined that the drainage has been completed. When it is determined that the process has been completed, intermediate dehydration is performed for a standard length of, for example, 3 minutes (step S5).
【００１３】これに対して、上記ステップＳ３で排水時

Determine whether or not (step S6),
As long as it is determined that the abnormal time has not exceeded the abnormal time T, the determination as to whether or not the drainage has been completed is made in the same manner as described above (step S7), and when it is determined that the drainage has been completed,
Next, perform intermediate dehydration for a time α (e.g. 1 minute) to the standard 3 minutes above.
(step S8).
【００１４】なお、上記ステップＳ６で排水時間ｔが異

Following the intermediate dehydration after washing, intermediate dehydration may be performed for the same length.

Since the detergent is squeezed out for a longer period of time, even if the start-up of the rotation is slow, the detergent can be squeezed out sufficiently.
Rinsing can also be performed reliably and efficiently.

する。[Effects of the Invention] As is clear from the above description, the washing machine of the present invention drains water after washing and during rinsing, and then performs intermediate dehydration to squeeze out detergent from the laundry. When water is drained before intermediate dewatering, the drain time is measured, and the measurement result is compared with the predetermined time.
Then, when it is determined that the drainage time is longer than a predetermined time based on the comparison results, the control is such that the subsequent intermediate dehydration is executed for a longer time than the standard time.
Thereby, even when drainage conditions are not good, intermediate dehydration can be performed to sufficiently squeeze out the detergent, and rinsing can be performed reliably and efficiently, which is an excellent effect.
