Description

How to rinse the washing machine

The present invention relates to a rinsing method of a washing machine. In particular, in a rinsing cycle of rinsing water while rinsing while supplying water, the rinsing water is sensed to detect contamination of the rinsing water to be rinsed. The present invention relates to a rinsing method of a washing machine by which a cleaner rinsing effect can be obtained.

In general, when you want to wash in a washing machine, the time and number of times are set by a predetermined program, which is a series of washing, washing, rinsing, and dehydrating strokes. It is meant to be built.

Therefore, when a series of laundry administrations are performed according to the predetermined time and number of times, for example, when laundering heavy laundry and non-contaminating laundry are washed separately, there is no problem in the case of washing, but the degree of contamination in the case of rinsing Heavy laundry has a problem that the desired number of rinsing effects can not be obtained by the set number of times, on the other hand, laundry that does not have a high degree of contamination can obtain the desired rinsing power without having to rinse the set number of times. Longer time, there is a problem that the resulting power consumption is increased,

Therefore, in the prior art, the user may arbitrarily vary the washing time and the number of rinsing times according to the degree of contamination, and may wash and rinse.However, when the rinse is detected, the degree of contamination is detected by resetting the number of times according to the detected degree of contamination. Although the rinsing may be performed, the washing time and the rinsing frequency may be set at random. During rinsing, the rinsing frequency may be exceeded (3 times) when the rinsing time is reset according to the detected contamination level. It has a problem that does not have a problem that can not achieve the desired rinsing effect.

An object of the present invention is to detect the contamination of the rinsing water drained during the rinsing of the main water rinsing while rinsing out of a series of washing strokes and stop the water supply rinsing if the detected contamination level is below a predetermined predetermined pollution degree, so that the dehydration It is intended to have a rinsing effect.

In order to achieve the above object, the present invention provides a step of washing in an initializing state and rinsing while water is supplied after the washing is completed and intermediate draining, and rinsing while rinsing in the step; Determining whether the detected contamination level is less than or equal to an arbitrarily set pollution level; and if the detected pollution level is not less than or equal to a randomly set pollution level, rinsing with water and drainage; If it is characterized in that the step of stopping the main rinsing and proceeds to the main dehydration.

If it is not less than the pollution degree (34) and the pollution degree detected in the contamination degree determination step 34 or less randomly set (0.3ph), continue rinsing while supplying and draining And, if the detected pollution degree is less than the randomly set pollution degree (0.3ph), stop the rinsing while stopping the water supply and draining the water supply rinsing step 35, and when the rinsing is stopped in the water rinsing stop step 35 Dehydration is to proceed to the main dehydration step 36 to complete.

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

First, the laundry is put in the washing tank while the power is supplied to the washing machine, and when a series of washing administrations to be washed in the microcomputer (B) is input through the driving signal input unit (A), the input of the microcomputer (B) is input. The water supply and drainage drive unit (C) is controlled while the operation signal is controlled according to a predetermined program, and the water is supplied to the washing tank 2 through the water supply port 8. Water supply by detecting the water level to the water level detector (6) through the).

Subsequently, when the water level reaches the predetermined level, the microcomputer (b) goes to the washing step 30 to control the motor driving part (e) to drive the motor 5 forward and reverse rotation. While the pulsator 3 rotates forward and backward by the forward and reverse rotation driving of the motor 5, water flow friction is generated and washing is performed, and the washing is performed for a predetermined washing time, and the washing is performed. During the washing completion determination step 31, it is determined whether or not the predetermined washing time has been completed by washing, and if the predetermined washing time is not completed, the washing process continues until the washing time is completed. On the other hand, if the washing time is completed, the water supply and drain driving unit (c) is controlled to drain the contaminated washing water through the drain (7), and then in the microcomputer (b) to the main water rinsing step (32) The water supply and drainage driving part (C) is controlled to supply water to the set water level through the water supply port (8), and the microcomputer (B) controls the motor driving part (E) to drive the motor 5 forward and reverse rotation. When the pulsator 3 is rotated forward and backward by the forward and reverse rotation driving of the motor 5, water flow friction is generated and rinsing is performed. At this time, the microcomputer (b) controls the water supply and drainage drive (C). By rinsing the contaminated rinsing water generated during rinsing through the drain hole 7, but the drainage of the rinsing water is not drained more than half with respect to the set water level (6). While rinsing, the rinse water is rinsed while adjusting the drainage amount of the rinse water.

As such, during the rinsing of the main water, the microcomputer (b) goes to the pollution detection step 33 and controls the pollution detection unit (bar) to rinse drained through the pollution sensor 9 mounted at one side of the drain hole 7. When the contamination level of water is detected at any time and inputted to the microcomputer (b), the microcomputer (b) goes to the pollution level determination step 34 to determine whether the pollutant level (0.3ph) or less arbitrarily set for the detected pollution level has been reached. In this case, if the detected pollution level does not reach a randomly set contamination level (0.3ph) or less, the microcomputer (b) determines that the pollutants are not rinsed cleanly in the laundry being rinsed, and thus the main water rinsing step 32 The rinse proceeds while continuing to rinse while supplying and draining water, and detecting and entering the degree of contamination of the drained rinsing water.

If it is determined that the pollution degree detected in the pollution degree determination step 34 has reached a randomly set pollution degree (0.3ph) or less as described above, the microcomputer (b) determines that the laundry is rinsed cleanly and rinses the water. Go to the stop step (35) to control the motor drive unit (e) to stop the rinsing by stopping the forward and reverse rotation of the motor (5), and to control the water supply and drain drive (c) to shut off the water supply port (8) The drain 7 is opened to drain the rinsing water to stop the main rinsing.

When the water rinsing is stopped, the microcomputer (b) goes to the main dehydration step 36 to control the motor driving part (e) to rotate the motor 5 at high speed in one direction to proceed with the main dehydration while rotating the washing tank at high speed. Will be done.

As described above, the present invention detects the degree of contamination of the wash water drained during the rinsing of the rinsing water in order to wash the laundry more cleanly and sanitarily. When the water is supplied, drained, and rinsed, and the detected pollution level reaches a predetermined pollution level or less, the main water rinsing is stopped and the main dehydration is performed, thereby providing a cleaner rinsing effect.
