BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric washing machine and a detergent container for washing general dirty items and laundry to clean them.

0002

2. Description of the Related Art In general, laundry treatment materials can be classified into laundry soap agents and cleaning aids (hereinafter, laundry treatment materials are referred to as detergents). When detergent is applied to dirty laundry,
Dirt adheres to the detergent and washes away, leaving the items being washed clean.

[0003] The above detergents have a penetrating action, adsorption, swelling,
Dispersion, emulsification, and foaming performance are required. Furthermore, finishing agents such as starch and fabric softeners are used to improve the texture of laundry, and cleaning aids that change water quality are used. This cleaning aid that changes the quality of water is used as washing water to suit each condition, as it is best to use soft water for main washing, hard water for rinsing, and soft water for final rinsing.

Conventionally, when washing clothes using an electric washing machine, the user puts the above-mentioned detergent and the like into the washing tub by eye.

[0005]

[Problems to be Solved by the Invention] When using conventional electric washing machines, the selection of detergent is determined based on the user's experience and the detergent manufacturer's advertisements and usage instructions.
In addition, the timing and amount of bleach and fabric softener used depended on the user's experience and taste, so the degree of cleaning and finish of stains varied, and sometimes it was necessary to wash the product twice. Something happened.

[0006] Furthermore, it is clear that the type of detergent and the amount of detergent used vary depending on the temperature of the washing water, the weight, type, and degree of soiling of the items to be washed.

[0007] In other words, conventional electric washing machines do not have the function of displaying to the user the selection of the type of detergent and the determination of the amount to use based on the above-mentioned multiple factor analysis, or the function of automatically carrying out the selection. Therefore, in the past, there was a problem in that the user of an electric washing machine had to manually supply detergent to the washing machine based on sensual experience. Furthermore, as mentioned above, when putting detergent into the washing tub by hand, there is also the problem that the detergent is scattered outside.

[0008] The present invention solves the above problem, and determines the type and amount of detergent by determining the weight and type of the items to be washed, the dirtiness of the items, and the temperature of the washing water. Another object of the present invention is to provide an electric washing machine that can be supplied with detergent, and to provide a detergent container containing detergent that is easy to use in the electric washing machine.

[0009]

[Means for Solving the Problems] In order to achieve the above object, the electric washing machine of the present invention has the following features: The washing machine is equipped with means for determining the type and amount of suitable detergent, and means for supplying the optimal type and amount of detergent to the washing tub at the optimal timing in the washing process. .

In addition, the detergent container of the present invention may be made of a material that dissolves in the washing water in order to supply an appropriate amount of detergent to the washing tub, or the detergent may be made of a material that dissolves in the washing water without being dissolved in the washing water and only the detergent may be absorbed by the osmotic pressure of the washing water. It is made of a material that dissolves in detergent water.

[0011]

[Function] According to the structure of the electric washing machine described above, the means for storing and supplying detergent prevents the detergent from scattering outside when the user manually puts the detergent into the washing tub.

Furthermore, by providing means for determining and supplying the type and amount of detergent by determining the type and weight of the fibers of the object to be washed, the dirtiness of the object and the temperature of the washing water, it is possible to washing operations can be facilitated.

[0013] Furthermore, according to the structure of the detergent container described above, since the structure is a capsule type detergent container that can supply the optimum type and amount of detergent to the washing tub at the optimum timing during the washing process, detergent can be supplied to the washing tub at the optimum timing. The feeding operation becomes easier.
