Abstract

PURPOSE:To enable the detection and judgment of quality of washing in a short time. CONSTITUTION:Detection of the amount of washing in a tank is conducted before and after the supply of water into the tank. In this case, as the ways of floating during the supplying of water and of containing water in the discharging of the water are different between chemical fibers such as nylon and natural fibers such as cotton, the detection results differ clearly before and after the supply of the water. The difference allows the judgment of the quality of the washing simply by detecting the amount of the washing. Thus, this method does not require so long time as in the separate detection of the quantity and quality of the washing.

In order to achieve the above object, the washing machine of the present invention comprises a detection means for detecting the amount of laundry in the tub, and the detection by the detection means supplies water to the tub. It is characterized in that it is provided with a judging means for judging the quality of the laundry from each of the detection results before and after the water supply.

[0007] For example, chemical fibers such as nylon have poor water absorbency, and therefore float on water when water is supplied and do not contain much water even after draining. On the other hand, since natural fibers such as cotton absorb water well, they sink in water when they are supplied with water and contain a large amount of water even after they are drained. From these facts, the detection results when the amount of laundry in the tub is detected differ accordingly, and the quality of the laundry can be judged from the difference.

Here, the amount of load applied to the motor 7 when the agitator 6 is rotated as described above differs depending on the quality of the laundry before and after the water is supplied into the inner tub 4. For example, chemical fibers such as nylon have poor water absorbency, and thus float on water when water is supplied. Therefore, even when the agitator 6 is rotated, the laundry is agitated before the water is supplied, but the water is agitated more than the laundry after the water is supplied, and the motor 7 is lightly loaded after the water is supplied than before the water is supplied. Comes to take. Therefore, in this case, the detection result of L1> L2 is obtained, and based on this, "YES" in the above step A10.
Is determined, the next step is to set the execution content of the driving suitable for it (step A11). In this case, it is the content that the stirrer 6 is repeatedly rotated forward and backward in a pattern of driving for 1.5 seconds-pausing for 0.8 seconds, performing "washing" for 10 minutes, "rinsing" once, and "dehydration". Is performed for 5 minutes, and the operation is next performed with this set content (step A12).

On the other hand, since natural fibers such as cotton have good water absorption, they sink in water when water is supplied. For this reason,
Even when the stirrer 6 is rotated, the laundry that is naturally overlapped before water is agitated, but after water is supplied, water is agitated to agitate the laundry that is submerged in water and the motor 7 A heavy load may be applied after water supply than before water supply, or a load of the same magnitude may be applied before and after water supply.
Therefore, in this case, the detection result of L1≤L2 is obtained.
Based on this, a "NO" determination is made in step A10, so next, the contents of the execution of the operation suitable for it are set (step A13). In this case, the stirring body 6
Drive for 1.8 seconds-rotate forward and backward repeatedly in a pattern of resting for 1.0 second, "wash" for 15 minutes, "rinse" twice, and "dehydration" for 6 minutes. Then, the operation is executed with this setting content (step A12).

As described above, in this structure, the amount of laundry in the inner tub 4 is detected by the phase difference detection device 16 before and after water is supplied into the inner tub 4 containing the laundry. Then, the quality of the laundry is judged from the respective detection results. In short, the quality of the laundry can be detected by simply detecting the quantity of the laundry. The time required to judge the quality of the laundry can be shortened without requiring a long time as in the case where the detection is separately performed.

In contrast to the above, FIG. 5 and FIG. 6 show the second embodiment of the present invention, and only the difference from the above embodiment will be described, which is an alternative to the phase difference detecting device 16 described above. A rotation speed detector 21 such as a tacho generator for detecting the rotation speed of the motor 7 is provided as the physical quantity detection means, and the detection signal is input to the control device 14.

After that, water is supplied in the same manner as in step A5 (step B5), and then drainage is performed by opening the drain valve 9 (step B6).
Is rotated (step B7), and when it is determined that 5 seconds have passed (step B8), the rotation speed detector 21 detects the rotation speed R2 of the motor 7 (step B9).

It is determined whether or not the rotational speeds R2 detected in step B9 (after water supply) are approximately equal (step B11).

Here, the rotation speed when the inner tub 4 is rotated as described above differs depending on the quality of the laundry before and after water is supplied into the inner tub 4. For example, chemical fibers such as nylon have poor water absorbability as described above, and therefore do not contain much water even after water is supplied and drained. For this reason, even when the inner tank 4 is rotated, there is almost no difference in the rotation speed between before water supply and after water supply (after drainage). Therefore, in this case, the detection result that the rotation speed R2 is almost equal to the rotation speed R1 is obtained, and based on this, the determination of "YES" is made in the above step B11. The execution contents are set in the same manner as step A11 (step B12), and thereafter, the operation is executed with the setting contents similarly to step A12 (step B13).

On the other hand, since natural fibers such as cotton have good water absorption, they still contain a large amount of water even after being supplied with water and drained.
For this reason, when the inner tub 4 is rotated, the rotational speed of the inner tub 4 has a large difference between before and after water supply (after drainage). Therefore, in this case, the detection result that the rotation speed R2 is higher than the rotation speed R1 (R1 <R2) is obtained, and based on this, the judgment of "NO" is made in the above step B11. Set the execution contents of the matched operation in the same way as step A13 (step B14),
After that, the operation is executed with the set contents similarly to step A12 (step B13).

Even in this case, however, the quality of the laundry can be detected only by detecting the quantity of the laundry, which is long as in the case of separately detecting the quantity and the quality. The time required to judge the quality of laundry can be shortened without requiring time.

The detection means for detecting the amount of laundry in the inner tub 4 is not limited to the phase difference detection device 16 and the rotation speed detector 21 described above. For example, a motor for rotating the stirring body 6 can be used. Alternatively, the change may be detected by observing a change in the terminal voltage of the No. 7 capacitor 22 (in this case, the routine is performed as in the first embodiment). Alternatively, the weight of the laundry may be detected together with the inner tub 4 (in this case, the routine is performed in the same manner as in the second embodiment).
