Description

Water Supply Control Method of Washing Machine

The present invention relates to a water supply control method of a washing machine, and in particular, when a user arbitrarily sets a water supply level and determines that the water supply level arbitrarily set by the user is correctly set for the washing amount, the correct water level for the washing amount is determined. It relates to a water supply control method of the washing machine to be washed while being set.

In general, when watering and washing the laundry to be washed, the washing amount is automatically sensed by the purge course, and the level of the detected laundry amount is determined to perform a series of washing administrations while supplying water to the determined water level. In addition, there is a method in which the user arbitrarily sets the water level for the amount of washing, and performs a series of washing administrations while supplying water to the set water level, but there is no problem when washing by the fuzzy course, but the user arbitrarily washes the water level And when washing after determining a series of washing administrations, in case water supply decision is sometimes made inadvertently by the user's carelessness, the water level may be supplied less than the amount of laundry or more than unnecessary amount of water. If less, it will damage the laundry, If compared to takryang the water level it is to have a lot of problems resulting in a waste of water.

Nevertheless, in the conventional washing machine, when the user arbitrarily sets the water level for the washing amount, the washing machine supplies water to the set water level and proceeds to washing without determining whether the arbitrarily set water level is the correct water level. There is still a problem that the laundry effect is reduced due to lack of water or oversupply, and the laundry is damaged or water is wasted.

An object of the present invention is to determine whether the washing water level at the time of washing at the time of washing, when the user arbitrarily set whether the water level is set arbitrarily correctly for the washing amount to proceed to the washing while the correct water supply is made for the washing amount Thus, due to the carelessness of the user is to reduce the washing effect or the damage of the laundry or waste of water due to lack of water level or excessive water supply.

In order to realize the above object, the present invention determines whether the washing course is a manual course in the initialization state, and if not the manual course, the washing process proceeds automatically according to the amount of washing, while the manual course supplies water randomly from the user. Determining whether the water level is set, and if the water level is not arbitrarily set by the user in this step, it waits until the water level is set. On the other hand, if the water level is arbitrarily set by the user, the washing amount is detected and Determining a water supply level according to the detected washing amount; and if the water supply level is determined in the step, determining whether the water supply level determined according to the washing amount matches the set water supply level; and If the determined water level and the set water level match, On the other hand, if the water supply level determined according to the washing amount and the set water supply level does not match, characterized in that the water is supplied to the water supply level determined according to the washing amount and proceeds to the washing.

3 is a flow chart for a water supply control method of a washing machine applied to the present invention, the washing course determination step 30 of determining whether the washing course to be washed in the initial state is a manual course rather than a purge course, and In the washing course determination step 30, if the input course is not a manual course, the water supply level is automatically determined according to the washing amount, and the purge washing step 31 proceeds with washing while supplying water to the determined water level, and the washing course judgment If the input course in step 30 is a manual course, the water level setting decision step 32 for determining whether the water level is arbitrarily set by the user to be washed and the water level setting step 32 are randomly selected from the user. If the water level is not set, the standby step 33 continuously waits until the water level is set, and the water level setting decision step 32 from the user. If the water level is set to the water level, the water level is determined in step 34 of determining the water level by detecting the amount of washing put, and the water level determined in the water level is determined in the water level determination step 34, and the water level arbitrarily set by the user. When the water level is determined according to the washing amount, if the water level is determined according to the washing amount, the water level is determined according to the washing amount. A water supply level 36 for supplying and completing water, a washing step 37 for performing washing when water supply is completed in the water supply step 36, and a water level for which the determined water level is set in the set water level determination step 35 If it is matched with the washing step 37 to go to proceed with the washing.

Referring to the operation of the present invention made as described above are as follows.

First, apply power to the washing machine, put the laundry to be washed in the washing tank (2) of the washing machine, and then select the desired washing course through the operation signal input unit, purge or manual, and wash, rinse, When the operation signal is input to the microcomputer (B) for the dehydration operation, the microcomputer (B) of the washing machine goes to the washing course determination step 30 according to a predetermined program, and the fuzzy course from the driving signal input unit (A). It is determined whether or not a manual course is input, and at this time, if a fuzzy course other than the manual course is input from the driving signal input unit (a), the microcomputer (b) goes to the purge washing step 31 and the preset purge is performed. The water level is determined for the amount of washing to be washed by the washing method. That is, in the microcomputer (b), the motor 5 is connected through a motor driving part (e). The water level is determined in the state of load acting on the motor 5 with respect to the amount of washing put while the pulsator 3 is rotated forward and reverse by controlling the water level. The water level is detected by the water level detector (D). After washing the water supply while sensing the water level.

However, if a manual course other than a purge course is input in the washing course judging step 30, it is determined to go to the water level setting judging step 32 to determine whether the water level is arbitrarily set by the user through the operation signal input unit. At this time, if the water level is not set arbitrarily from the user, the microcomputer (b) does not go to the standby step 33 to supply water, and waits until the water level is set from the user.

On the other hand, if the water level is arbitrarily set by the user in the water level setting step 32, the microcomputer (b) determines the water level to determine whether the water level set by the user is correctly set according to the washing amount. Go to 34) to control the motor 5 through the motor driving part (e) and to rotate the pulsator (3) forward and reverse to determine the water supply level with respect to the amount of washing put into the load state acting on the motor (5) .

When the water supply level is determined according to the washing amount as described above, the microcomputer (b) goes to the setting level determination step 35 to determine whether the water supply level determined according to the washing amount and the setting water supply level arbitrarily set by the user coincide with each other. At this time, if the water supply level determined according to the washing amount does not match the set water supply level arbitrarily set by the user, the microcomputer (b) goes to the water supply step 36 and does not proceed with water supply to the water supply level arbitrarily set by the user. Water is supplied to the washing tank 2 through the water supply valve 7 of the water supply and drainage drive unit (C) at a water level determined according to the washing amount, and the water level is supplied through the water level sensor 6 of the water level detection unit (D). When the water supply is detected, the reason is that the water level arbitrarily set by the user is more or less than the amount of laundry to be washed. W laundry damage and or unnecessary waste of the washing water is, of course, in order to prevent that the washing effect decreases.

In this way, when the water supply is completed through the water level detector 6 of the water level detection unit D during water supply to the water level determined according to the washing amount, the microcomputer (b) goes to the washing step 37 and the motor. The motor 5 is rotated forward and reverse through the driving unit e. The forward and reverse rotational power is performed while the pulsator 3 is rotated forward and reverse through the gear unit 4.

However, when the water level is determined according to the washing amount and the water level is set arbitrarily set by the user as the determination result in the set water level determination step 35, go to the washing step 37 and the motor (5) through the motor driving unit (e). Forward and reverse rotation, this forward and reverse rotational power is to proceed to the washing immediately while rotating the pulsator 3 forward, reverse through the gear unit (4).

As described above, the present invention does not automatically determine the water supply level by washing the purge course, but when the user sets the water supply level arbitrarily, is the water level set arbitrarily accurately for the washing amount? By determining that the washing water is set while the correct water level is set for the washing amount, the washing effect is reduced due to lack of washing water or excessive water during washing, as well as preventing damage to laundry and waste of washing water. It will provide an effect that can be done.
