Kaisho
It is described in Publication No. 58-141181. However, detergents are generally less soluble at lower water temperatures, and therefore, within a predetermined washing time, the cleaning rate varies depending on the dissolution rate of the detergent. (c) Problems to be solved by the invention By dissolving detergent as quickly as possible according to the water temperature, the washing machine of the invention solves the difference in cleaning efficiency caused by the difference in the dissolution rate of detergent at each water temperature. It is something that shrinks the . (d) Means for Solving the Problems The washing machine of the present invention has a method in which, at the beginning of a normal reversing cycle, the rotation time of the rotor blade is relatively long or the rest time is relatively short with respect to the reversing cycle. Furthermore, the higher the temperature detected by the temperature detection device that detects the water temperature in the washing tub, the longer the time of the initial cycle. (e) Effect: In other words, the lower the water temperature, the longer the initial cycle will run to dissolve the detergent as quickly as possible. (F) Embodiments Examples of the present invention will be described based on the drawings.
However, the same reference numerals are used for the same parts as in the conventional example, and the explanation is omitted. As shown by the dotted line in FIG. 7, 17 is a negative characteristic thermistor that is installed in the air trap 12 and serves as a temperature sensor.When the machine is submerged in water, it detects the water temperature, and when it is not, it detects the air temperature inside the machine.

[Table] The temperature rank display circuit 29 consisting of a light emitting diode corresponds to each temperature rank,
The microcomputer 18 lights up a light emitting diode according to the determined temperature rank. The operation will be explained based on the above configuration. It should be noted that this embodiment deals with washing and rinsing steps, and the other operations in the dewatering and draining steps are similar to those of the conventional method.

[Table] Here, the explanation will be continued assuming that the operator selects the washing A process and the water temperature is less than 12°C, that is, the washing A process time is 14 minutes. In the washing process, the rotary blade 6 is driven in a main reversal cycle consisting of a plurality of single periods of long rotation in one direction and short single periods of rotation in the other direction, as shown in FIG. That is,
T 1 (0.7 seconds) < T 2 (0.8 seconds) < T 3 (1.0 seconds) < T 4 (1.2 seconds)
<
T 5 (1.3 seconds), and the pause time T 0 =0.5 seconds. Here, if the main reversal cycle is continued for a long time, the laundry in the tub will stagnate, so the water flow will be a little stronger, that is, the left and right rotation times will be the same and relatively long, and the pause time will be longer than T 0 . An auxiliary reversal cycle, which is a collection of a plurality of short single cycles, is inserted into the main reversal cycle to appropriately loosen the laundry, thereby improving the cloth circulation in the tub. Specifically, as shown in Figure 3, an auxiliary reversal cycle (approximately
9.9 seconds) into the shaded area in Figure 1 in a pulse manner.
In other words, the remaining time is 13 minutes, 10 minutes, 7 minutes, 5 minutes, 2
Insert at the minute. In addition, in Table 2, the numbers in parentheses indicate the number of times the auxiliary reversal cycle is inserted.For example, even in the same washing process A, if the water temperature is 12°C or higher, the process time is reduced to 12 minutes. will be set, so it will automatically
It will be inserted four times in total: 10 minutes, 7 minutes, 5 minutes, and 2 minutes. In other words, the higher the water temperature, the shorter the process time, and at the same time, the fewer times the auxiliary reversal cycle is inserted. This is because, as is clear from the experimental results shown in Figure 6, the higher the water temperature, the easier the laundry (cloth) will rotate (better cloth rotation); therefore, the higher the water temperature, the higher the washing rate. This is because laundry is less likely to stagnate. Next, as shown in Fig. 1, immediately after the start of each of the washing steps A, B, and C, a cycle consisting of a plurality of monotonous periods in which the left and right rotation times are 1.0 seconds each and the pause time is 0.2 seconds as a detergent-dissolving water stream is performed. is running. In this way, the detergent can be dissolved quickly, which is very effective in improving the cleaning rate. Moreover, since the higher the water temperature, the easier the detergent dissolves, as shown in Table 3, by automatically changing the execution time of the detergent dissolving water flow according to the water temperature, this time can be kept to the necessary minimum.

[Table] Finally, just before the end of each of the washing steps A, B, and C, the left and right rotation time is 0.2 to 0.4 as a loosening water stream.
A cycle consisting of multiple very short single cycles with a pause time of 0.2 seconds is performed for about 10 seconds. By doing so, the entire tub is swung, the laundry is evenly distributed in the tub, and it is possible to prevent an uneven load from being applied to the tub during the next spin-drying process. Here, the above main reversal cycle is for the case where the standard water flow is set, and by the way, in the case of strong water flow, T 0
= 0.2 seconds, and in weak water flow T 1 = 0.4 seconds, T 2 = 0.4
seconds, T 3 = 0.5 seconds, T 4 = 0.6 seconds, T 5 = 0.7 seconds, T 0 = 1.6
Seconds. From the above, in this embodiment, the auxiliary reversal cycle is more effective than the main reversal cycle when the rotor blade 6 is
Since the ON time is relatively long and the OFF time is short, it generates a stronger water flow than the main reversal cycle, which is convenient for loosening laundry that tends to stagnate. Although this embodiment has been explained using a washing process as an example, it is also fully applicable to a rinsing process. (g) Effects of the invention The washing machine of the invention has an initial cycle for dissolving the detergent at the beginning of the washing process, so the detergent dissolves better, and the lower the water temperature, the longer the initial cycle is executed. Therefore, even if the water temperature is low, the detergent dissolves quickly, and as a result, the difference in cleaning efficiency caused by the detergent dissolution rate can be reduced.
