Description

Condition table of washing machine {a condition table of a washer}

The present invention relates to a washing machine, and more particularly, it is possible to set a washing condition according to an area by dividing the washing form into an appropriate area according to the condition of the wash water and the user's habit of supplying water. The condition table of the washing machine is improved and the use of energy is reduced.

In general, a washing machine is a machine that removes stains on clothing by providing a mechanical action using electricity.When it is put on clothing, it is removed from the fibers by the chemical action of detergent when put in the washing liquid, Because it takes time, if the water flow is forcibly generated and mechanical action such as friction or vibration can be removed quickly and easily.

Conventional washing machines are rotatably positioned inside an outer tub in which the wash water is freshly installed, and an inner tub for accommodating the laundry is installed therein, and a washing vane rotatably installed in the center of the inner tub, causing washing water flow to the washing tub. The inner tank or the laundry blade is selectively rotated by the motor and the clutch mounted on the lower side.

In order to perform the washing process smoothly, a conventional washing machine generally includes a quantity sensor for detecting a quantity of laundry contained in the outer tub, and a level sensor for measuring the level of fresh water in the outer tub.

Recently, a washing machine has been developed in which an electrode sensor for detecting a difference in conductivity due to a conductive material included in washing water is installed at a lower side of a washing machine so that a predetermined washing pattern is formed according to the hardness of water.

To this end, one side of the outer tank is provided with an electrode sensor and a temperature sensor connected to the controller to measure the conductivity and temperature of the wash water supplied to the outer tank, respectively.

Here, the washing water is supplied to the outer tank and the detergent value of the electrode sensor is converted to the conductivity of the washing water in the controller while the detergent is supplied together, and the temperature of the washing water is measured by the temperature sensor. The hardness of the wash water and the amount of detergent dissolved in the wash water are calculated according to the measured conductivity and temperature of the wash water, and the operation of the washing machine is controlled according to the hardness and the detergent amount of the wash water.

The microcomputer inputs a plurality of linear graphs having a variable washing performance index according to temperature to set one graph selected by the temperature sensed by the temperature sensor and a hardness of a position where the conductivity sensed by the electrode sensor is orthogonal to each other. Will be.

However, in the related art, a large number of temperature graphs are input according to the temperature conditions, and thus the speed is delayed. Thus, the temperature graph is simplified to speed up the processing time. Accordingly, proper hardness cannot be selected, so washing is not efficiently performed. There was a problem that the washing time is increased.

The present invention has been made in order to solve the above problems of the prior art, by subdividing the temperature sensor and the electrode sensor according to the washing conditions to create a table in the area corresponding to the temperature and conductivity measured by the temperature sensor and the electrode sensor The hardness is set accordingly to provide a condition table of a washing machine that can be quickly and accurately washed.
