Conventional Example Conventionally, the washing time and number of rinses of a washing machine have been set by a timer cycle, or the user has determined the washing time and number of rinses based on experience and feeling. Therefore,
A problem has arisen in that washing time and water are wasted. Therefore, a washing machine with a sensor function that detects the turbidity of the washing liquid and the rinsing liquid to determine the washing time and the number of rinses was devised.

The sensor has a light emitting element and a light receiving element. The inner wall surface of the detection section to which the sensor consisting of the light emitting element and the light receiving element is attached becomes dirty when the washing machine is used for a long period of time. If the inner wall surface of the detection section becomes dirty, the turbidity of the washing liquid and rinsing liquid cannot be accurately detected, and the sensor may make an incorrect judgment.

Before washing, there is no water in the outer tank (2), so the float (7) is at the bottom of the detection tube. Inner tank (4)
When clothes and detergent are put into the tank and water is supplied, the inner tank (4)
The water inside flows into the detection tube (6). Then, as the water surface rises, the float (force) rises.As the float (7) rises, the underwater brush (8) also rises.At this time, the underwater brush (8) touches the inner wall of the detection tube (6). It rises while scrubbing.In other words, the water-filled brush (8) moves up the inner wall, making it easier to remove dirt.Then, the float (force) and the brush (8) are used to remove dirt from the detection tube (6) during washing.
The light emitted from the light-emitting element 03) of the detector cannot be blocked. Tube that detects changes in turbidity of washing liquid (6)
When the water level in the inner tank (4) decreases, the water level in the detection tube (6) also decreases, and the float (7)
) and the brush (8) descend within the detection tube (6) accordingly. Since the brush (8) is covered with washing liquid containing detergent, and the inner wall of the detection tube (6) is filled with washing liquid, dirt on the inner wall can be removed very easily. As described above, the inner wall of the detection tube (6) to which the detector is attached can be cleaned using the upper and lower parts of the water surface.

In the case of rinsing, a float (force) moves up and down inside the detection tube (6) to clean the inner wall.

The transmittance of light emitted from the light emitting element 03) of the detector (9) is as shown in FIG. 3, and the transmittance decreases as the amount of dirt increases. Initially, when the detector (9) was installed, the part was clean and the detector (9) had a characteristic of transmittance I, but when the detector was installed, the inner wall of the part became dirty, for example, as shown in Figure 3A. The transmittance is ▪, which is lower than that of I without dirt. If the transmittance at the initial stage of washing differs, the detection characteristics of the detector will differ. However, as in the present invention, the detection accuracy of the detector (9) can be kept constant over a long period of time by cleaning the detection section during each washing and rinsing process.
