Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an electric washing machine capable of soaking and washing.

[Conventional technology]

In recent years, as clothing has become more luxurious and fashionable, the number of clothes that are difficult to wash with regular water has increased, and to reduce damage to delicate clothes, it is necessary to wash them with a wet cloth.
Washing is being carried out. However, delicate clothing such as slumbers, blouses, underwear, etc. may not come into direct contact with the skin.
Although there is a lot of dirt and it is relatively easy to get dirty, this type of cleaning reduces damage but reduces the cleaning power.

On the other hand, in the washing technique since ancient times, when washing heavily soiled clothes, soaking the clothes in a cleaning solution with pickled soap, so-called soaking, has been carried out.

The same is true for electric washing machines, especially since Compact 1 detergent containing proteolytic enzymes has become mainstream recently, so soaking and washing is the best way to bring out the effects of the enzymes in such detergents. It can also compensate for the cleaning power that decreases with net 1 washing.

However, if the clothes are left soaked for a long time, the separated dirt will re-adhere to the clothes, causing a phenomenon known as re-contamination.

Therefore, as shown in Japanese Unexamined Patent Publication No. 1159/1983, it is also possible to stir the laundry and detergent solution by driving the washing motor for a short period of time several times at intervals during Vf washing. be exposed.

(Problems to be Solved by the Invention) The washing machine capable of soaking and washing shown in the above-mentioned Japanese Patent Application Laid-Open No. 64-1159 is intended for a single-tank fully automatic washing machine, and after soaking and washing is done automatically. The washing process started immediately, and it was not possible to choose only soaking and washing.

Further, the automatic washing timer for setting the washing process and the soak timer for setting the soaking process are provided separately for operational purposes, and are only linked by a cam switch connection.

The purpose of the present invention is to solve the above-mentioned disadvantages of the conventional example, to allow only soaking and washing to be performed, and to simplify the soaking and washing operation by simply changing the direction of rotation of the timer knob without adding any additional equipment. There is a place that provides washing machines.

[Means to solve the challenge]

In order to achieve the above-mentioned object, the present invention incorporates a timer for setting the ■ and ↑ limits of soaking washing into a normal washing timer, and simply changing the direction of rotation of the cent of the timer knob allows soaking washing to be performed. The main feature is that the time limit can be set, and a course change button switch is provided to select whether or not to continue the washing process after the soaking and washing process is completed.

[Function] According to the present invention, by simply turning the timer knob of a normal washing timer in the opposite direction of the normal washing process, it is possible to set special conditions for soaking and washing for a desired period of time.

After setting the timer, the washing motor goes through a reverse operation to dissolve the detergent well, and then repeats a pause, a short-time operation, and a pause to run the soaking LJ left-washing course. The water flow generated during operation can prevent color unevenness caused by a certain amount of bleach contained in detergent, and
Helps separate dirt.

Furthermore, if you select "Only for soaking" with the course changeover button switch, the operation will stop after the 1st cycle of soaking and washing is completed. On the other hand, if you select "Soak → Wash" with the costume change button switch, after the Sei & J Soak wash course ends, the 6-wash wash course is automatically entered and washing begins.

〔Example] Embodiments of the present invention will be described in detail below with reference to the drawings.
