っていた。(Prior Art) Recently, various fully automatic washing machines have been developed that control washing or rinsing operations by optically detecting changes in the transparency of the cleaning liquid. It was a problem. In other words, if there is dirt on the detection window of a device that optically detects the transparency of the cleaning liquid, the dirt on the detection window will increase the transmittance of light, making it impossible to accurately detect the transparency of the cleaning liquid. This made it difficult to carry out normal control.

転時に行なうべく構成する。The fully automatic washing machine according to the embodiment of the present invention has the above-mentioned configuration, and, like conventional fully automatic washing machines, each operation such as water supply, washing, rinsing, and spin-drying is performed sequentially according to a predetermined program. An example of this is shown in FIG. and,
The washing and scrubbing operations are controlled by detecting changes in the clarity of the washing liquid, as described below. In addition, the intermediate dehydration and final dehydration operations are divided into the first and second stages; in the first stage, a motor (not shown) rotates the washing and dehydrating tank 2 to perform dehydration, and in the latter stage, the power to the motor is stopped and washing is performed. Dehydration is carried out by the inertial rotation of the dehydration tank 2, and the cleaning of the θ1j constant portion 14, which is a feature of the present invention, is configured to be performed during the later inertial rotation.

動作を制御する。- In the configuration described above, when the pulsator 3 rotates during washing or suctioning operations, the cleaning liquid in the water tank 1 is circulated inside and outside the washing/dehydration tank 2 through the holes in the washing/dehydration tank 2, and a part of the liquid flows through the circulation port. 17, the pipe I8, the pipe section 11 including the measuring section 14, and the water collection 1]16 are circulated in red. The light source 23 and the photosensitive element 24 detect changes in the transparency of the cleaning liquid flowing through the measuring section I4, and control operations such as washing or washing.

動作に移行する。FIG. 4 is a diagram showing changes in the transparency of the cleaning liquid during washing, with the solid line A indicating fresh water and the solid line opening indicating the transparency of the liquid. During washing, the transparency of the liquid in the water tank I gradually decreases due to dirt etc. from the laundry, and when there is no change in transparency, it is determined that the washing is complete, the washing operation is completed, and the next step is the draining operation. to move to.

できる。On the other hand, cleaning of the measuring unit 14 is performed by opening the cleaning solenoid valve 28 when transitioning to inertial dehydration in the latter half of the dehydration operation, and cleaning the water storage tank 2.
The fresh water in 7 passes through the solenoid valve 28 and the hose 29 to the measurement unit 14.
This is done by washing away dirt that has flowed into the interior of the sensor window 213.22a and adhered to the surface of the detection window 213.22a. At this time, since the washing and dehydrating tank 2 is rotating inertia, the measuring section 1
Each part including 4 vibrates finely, and the supplied clean water is also vibrated, resulting in a tapping cleaning effect, compared to when it flows quietly on the surfaces of the detection windows 21a and 22a. dirt can be removed efficiently, resulting in extremely effective cleaning. Therefore, the detection windows 21a and 22a are always kept clean and the C transmittance remains constant, making it possible to accurately detect changes in the transparency of the cleaning liquid during washing or rinsing operations.
