Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for rinsing a washing machine in which the rotation of a pulsator is controlled by an electronic program timer.

Conventional technology Conventionally, the water flow during rinsing in washing machines in which the rotation of the pulsator is controlled by an electronic program timer is set before the start of operation, and as shown in Figure 6, the water flow during the rinsing process does not change, and the water flow is set at the initial setting. Stirring was performed using a chisel. 6th
In the figure, t indicates time, to indicates the start of rinsing, and , and indicates the end of rinsing. Further, the waveform in the graph schematically represents the water flow, and λ2 indicates the initial setting water flow.

Problems to be Solved by the Invention Figure 4 shows the state at the end of dehydration in normal washing, where 1 is the wall of the washing tub and 2 is the clothes in the washing tub.

In the conventional method as described above, due to strong centrifugal force due to dehydration before the rinsing process, the clothes 2 in the washing tub become stuck to the washing tub wall 1 as shown in FIG. 4, and the rinsing process starts. Even if the clothes 2 in the washing tub are soaked in the rinsing liquid, there is a problem that the rinsing process ends with the clothes 2 hardly moving in the state shown in FIG. 4.

Further, FIG. 7 shows an example in which the water flow during rinsing is changed.

λ in the graph of the figure is the cloth conditioning water flow, and λ2 is the initial setting water flow. This is used as a stream of water to condition the cloth at the stage before draining at the end of the rinsing process, in order to prevent clothes from becoming unbalanced when dehydration is started after rinsing.

In addition, Figure 5 shows the pulsator's rotation speed being variable.

This shows an electronically controlled washing machine that is capable of washing delicate clothes immediately before rinsing starts, and 3 is the clothes in the washing tub. Since the washing capacity of delicate clothes such as wool knits is generally around 1.0 kg, the bulk of the load is not large. In the conventional method shown in FIG. 7 as described above, there is a problem that the rinsing process ends with the clothes 3 in the washing tub floating on the surface of the rinsing liquid without being penetrated by the rinsing liquid.

The present invention solves these problems.

The purpose of this is to quickly adapt the clothes in the washing tub to the rinsing liquid after the rinsing process starts, improve the movement of the cloth, and improve the rinsing effect.

Means for Solving the Problem In order to solve this problem, the present invention provides a method in which, in the rinsing process of a washing machine in which the rotation of a pulsator is controlled by an electronic program timer, a water flow stronger than the initially set water flow is used for a predetermined period of time after the start of rinsing. Stirring is first performed, and then stirring is performed using the initially set water flow.

Effect: With this configuration, after the rinsing process starts, the clothes in the washing tub become more easily immersed in the rinsing liquid due to the force of the water flow stronger than the initially set water flow, and the movement of the cloth is improved.

EXAMPLE Hereinafter, an example of the present invention will be described based on one drawing.

First, the case of normal washing will be explained with reference to FIG. 1, FIG. 2, and FIG. 4.

Figure 1 schematically represents the rinsing water flow of a washing machine in which the rotation of the pulsator is controlled by an electronic program timer in an embodiment of the present invention, where t is time, Lo is the start of rinsing, and □ is the end of rinsing. Show the time. In addition, the waveforms in the graph are schematic representations of water flow; λ2 indicates the initial setting water flow, λ1 indicates a water flow stronger than the initial setting water flow, and Figure 2 shows that the clothes move sufficiently in the washing tub during the rinsing process. 11 is the clothes in the washing tub.

As shown in FIG. 1 above, when the water flow for the rinsing step is set and the rinsing step is started, the clothes in the washing tub are in the state shown in FIG. 4 due to the strong centrifugal force caused by dewatering before rinsing. However, at the beginning of the rinsing process, a water flow stronger than the initial setting water flow is generated, so the clothes 2 stuck to the washing tub wall 1
The cloth loosens easily, absorbs the rinse solution quickly, and allows the cloth to move better. As a result, the rinsing effect is improved.

In the normal washing described above, the strong water flow λ1 makes the ON time of the pulsator reversal time longer than that of the initially set water flow λ2. In this case, in a washing machine that can be set to strong, standard, and weak water flow, the same thing will happen if the strong water flow λ1 is set to one level stronger than the initial setting level of the water flow λ2. however,
If the initial setting water flow λ2 is a strong water flow, the strong water flow λ1 is λ2.
is equal to

In addition, the rotation speed of the pulsator can be varied (e.g. 170 rpm) for washing delicate clothing such as wool knits.
An electronically controlled washing machine has been devised that has a speed of 8 orpm. When the rotation speed of the pulsator is low, a strong water flow λ1 cannot be handled by making only the reversal time variable. This can be countered by increasing the pulsator rotation speed of the strong water flow λ□ and varying the reversal time. In this case, the same thing can be said if 1 strong water flow λ is the level of the weak water flow mentioned above.

Next, the rinsing process for delicate clothing such as wool knits will be explained with reference to FIGS. 3 and 5. In FIG. 3, reference numeral 12 indicates the clothes in the washing tub, and the clothes 12 are shown in a state where they are sufficiently moving in the rinsing liquid. For a while after the start of rinsing, the clothes in the washing tub remain floating on the surface of the rinsing liquid without being penetrated by the rinsing liquid, as shown in FIG. Here, if you set the water flow for the rinsing process as shown in Figure 1,
At the beginning of the rinsing process, a water flow that is stronger than the initial water flow is generated, so that the clothes floating on the surface of the rinsing liquid are drawn into the rinsing liquid and are easily penetrated by the rinsing liquid. As a result, clothes move better in the washing tub.

The state shown in FIG. 3 is reached, and the same effect as in cases other than delicate clothing is produced.

Effects of the Invention As described above, according to the present invention, in normal washing, after the start of the rinsing process, a water flow stronger than the initially set water flow is generated by controlling the pulsator reversal time, so that the clothes in the washing tub are loosened and quickly absorbed into the rinsing liquid. It will blend in and the movement of the cloth will improve. As a result, rinsing performance is improved and rinsing time can be shortened. There is also a method of controlling the reversal time at the same time as the pulsator rotation speed of a strong water stream when washing delicate clothes, and the same effect can be achieved in this case as well.
