Abstract

PURPOSE:To set the time limit when clothes are soaked in a detergent solution for a desired time by a knob for a usual washing timer being only turned in the opposite direction of setting of a usual washing process, by providing a stream-selecting switch whereby the strength of a stream caused for a short time when the clothes are soaked in the detergent solution can be selected in several stages as well as usual washing. CONSTITUTION:In an electric circuit for the title washing machine, a stream- selecting switch 12 is connected to one timer motor 8 through a contact point S4 for controlling a soaking time limit and branched into contact points S5, S6. They are also connected to contact points S2, S3 for stream reversal used for controlling a washing motor 11. After operation is started, the contact point S4 is closed on the side of a point (b) for three minutes and the washing motor 11 is driven and a detergent is dissolved in water by the stream reversal. For this stream reversal, when the stream-selecting switch 12 is pushed, either of the contact points S5, S6 is closed and according to that, either of the contact points S2, S3 for the stream reversal is closed, and thus the strength of the stream is selected.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an electric washing machine that can be soaked and washed.

[Conventional technology]

In recent years, as clothing has become more luxurious and fashionable, there has been an increase in the number of clothes that are difficult to wash with regular water.For delicate clothes, to reduce damage, it is necessary to cover them with Ne. is being carried out. However, many delicate clothes, such as socks, blouses, and underwear, are worn directly on the skin and are relatively easy to get dirty, so washing them on the net reduces damage but reduces cleaning power.

On the other hand, in laundry technology since ancient times, when heavily soiled clothing is washed, it has been soaked in a cleaning solution, so-called soak washing.

This is the same for electric washing machines, and especially recently, Konbaku 1 detergent containing proteolytic enzymes has become mainstream, 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 when washing online.

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 Patent Application Laid-Open No. 64-1159, the washing motor is driven for a short time several times at intervals during soak washing to stir the laundry and detergent solution.

[Problem to be solved by the invention]

Kiyoshi'J shown in the above-mentioned Japanese Patent Application Laid-open No. 11.59/1983
In the washing machine, the laundry is soaked and washed.
There is only one water flow for stirring the detergent solution.
It was not possible to adjust the amount according to the amount of washing material.

In addition, it is aimed at tank-type fully automatic washing machines, and the automatic washing timer that sets the washing process and the sorter timer that sets the fresh and J-washing are separated for operational purposes. They are only related by connections.

The purpose of the present invention is to solve the above-mentioned disadvantages of the conventional example, and to select the strength of the water flow during soaking in response to stains, thereby preventing re-contamination during washing after soaking, and making it possible to clean the cloth even when washing it in the dryer. To provide a washing machine which can effectively remove dirt with less damage, and which can easily perform soaking washing by simply changing the direction of rotation of a timer knob without adding a separate device.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention incorporates a timer that sets the time limit for soaking washing into a normal washing timer, and changes the direction of the timer knob setting.
With this feature, it is possible to set the time limit for washing after soaking for seven days, and the water flow can be selected in several steps to reduce the strength of the short-time sudden water flow during washing after soaking. Switching switch 2
The main point is that the

[Effect]

According to the present invention, the time limit for soaking and washing for a desired time can be set simply by turning the timer knob of a normal washing timer in the opposite direction of the normal washing process.

After the timer starts, the washing motor runs in reverse order to prevent the detergent from dissolving well, and then goes through a cycle of soaking and washing by repeating pauses, short-time runs, and stops, and then short-time runs. The water flow generated at the time of washing can prevent color unevenness caused by a certain amount of bleach contained in detergents, and also help separate stains.

Furthermore, the water flow generated during this short-time operation can be selected depending on the dirtiness of the laundry by pressing a water flow switching switch.
