Description

Description: TECHNICAL FIELD The present invention relates to an electric washing machine that can be dipped and washed.

[Prior Art] In recent years, clothes that are difficult to wash with normal water flow are increasing due to the high quality and fashion of clothes, and delicate clothes are covered with a net or washed to reduce damage. Is being done. However, many delicate clothes, such as stockings, blouses, and underwear, are directly attached to the skin and are relatively easily soiled. Therefore, such net washing reduces damage but reduces detergency.

On the other hand, in the technique that has been selected for a long time, when selecting heavily soiled clothes, so-called dipping and washing is performed in which the clothes are soaked in a cleaning liquid.

This is the same for electric washing machines, especially since compact detergents containing proteolytic enzymes have become the mainstream these days, soaking and washing is the best way to bring out the effect of the detergent containing enzymes. It is also possible to make up for the deteriorating power that decreases with.

However, if left soaked for a long time, there is a disadvantage that the separated dirt is redeposited on the clothes and recontamination occurs.

Therefore, as disclosed in Japanese Patent Laid-Open No. 64-1159, the washing motor may be driven for a short period of time a plurality of times at intervals during the pickling and washing to stir the laundry and the detergent solution.

[Problems to be Solved by the Invention]

The washing machine that can be immersed and washed in Japanese Patent Laid-Open No. 64-1159 is intended for a single-tank fully automatic washing machine.After the immersion and washing, the washing process is started automatically. You can not choose the work of only standing and washing,
The water flow for agitating the laundry and the detergent solution during the soaking and washing was set to one, and it could not be added depending on the amount of the laundry.

Further, the automatic washing timer for setting the washing process and the soak timer for setting the submerged washing are separately provided for operation, and are only related by connecting the cam switch.

The object of the present invention is to eliminate the inconvenience of the conventional example, and to perform only the soaked and washed, and to recontaminate the soaked and washed by selecting the strength of the water flow at the soaked and washed according to the dirt. Without washing, you can effectively remove dirt by washing the net and cloth damage, and you can change the direction of rotation of the timer knob without adding a separate device to make it easy to pick and store. To provide a machine.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention is configured such that a washing timer for setting a washing process is a 360-degree rotating type, a timer for setting the first half of the washing timer for the washing process, and a timer for setting the washing process by soaking the latter half. In addition, the time limit of the soaked and washed in the soaked and washed process can be set to a desired time by picking a timer, and a course change button switch for selecting whether to continue the washing process after the soaked and washed process is completed. The gist of the present invention is to provide a water flow changeover switch capable of selecting the strength of the induced water flow for a short period of time during washing by soaking.

[Action]

According to the present invention, it is possible to set the time limit for soaking and washing for a desired time simply by rotating the timer knob of the normal washing timer in the opposite direction to the setting of the normal washing process.

Then, after the timer starts, the washing motor runs through a reversing operation to dissolve the detergent well, and then a pause, a short run, and a soaking and washing course operation by repeating the pause. The generated water stream can prevent color unevenness due to the bleaching component contained in the detergent, and also help to separate stains.

Further, when "only put on" is selected by the course change button switch, the operation is stopped at the end of the soaking and washing course. On the other hand, when "Place and wash" is selected by the course changeover button switch, after the end of the pickling and placing wash course, the course automatically shifts to the washing course and washing is started.

In addition, the water flow caused by a short-time operation can be selected according to the soiling of the laundry by pressing the water flow switching switch.
