Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a control device for a washing machine equipped with a soak washing course.

Conventional technology Conventionally, in the soak washing cycle of this persimmon washing machine, after water has been supplied to a preset water level, first, after a predetermined period of time has elapsed, the machine is rotated in reverse to disperse the detergent into the water and soak it into the laundry. let Thereafter, the stirring blades are rotated in reverse for a predetermined time every time a predetermined period of time elapses, and this operation is continued for about one hour in total.

The washing time in the washing process after the soaking process was set in advance, regardless of the soaking time.

Problems to be Solved by the Invention (1) In the conventional washing machine control device, in the case of a soaking wash course, the laundry is soaked for a certain period of time and washed for a certain period of time, regardless of the degree of dirtiness of the laundry. ing. Therefore, if the laundry is not sufficiently submerged or has heavy oil stains, the dirt may not be removed sufficiently, and if there is only partial dirt, there is a problem of excessive agitation and damage to the fabric. Ta.

The present invention solves the above problem, and by detecting the amount of laundry and determining the degree of soiling of the laundry in the soak washing course, it is possible to optimally set the soak washing time and washing time. The purpose of the present invention is to provide a control device for a core washer that can perform the following functions.

Means for Solving the Problems In order to achieve the above object, the present invention provides a dirt level detection means for detecting the dirt level of the water in the washing tub, and a soaking/washing system.
The apparatus is equipped with a control means for automatically operating the rinsing and dehydrating processes.

Operation With the above configuration, the degree of contamination of the water is detected after a predetermined period of time E#f has elapsed since the degree of contamination has been detected, and the control means sets the degree of contamination of the water to full open when the water is turned on based on the amount of change.

EXAMPLE Hereinafter, an embodiment 4A of the present invention will be explained with reference to FIGS. 1 to 3. As shown in the figure, the pulsator 1 is connected to the washing tub 2.
The power of the motor 3 drives the pulsator 1 through the deceleration device 4, and the electromotive force data when the motor 3 is stopped is used to detect the amount of laundry applied to the pulsator 1 at this time. The amount is input to the amount detection means 6. The water level detection means 6 detects the water level in the washing tub 2 supplied with water by the water supply means 7.
The sensor 10 detects the permeability of water, and converts the permeability of water in the V washing tub 2 into voltage using a sensor 10 provided on the upper part of the drainage means 9 and detects the voltage. The control means 11 inputs signals from the cloth amount detection means 5, the water level detection means 6, the dirt level detection means 8, etc., and outputs the signals from the motor 3, the water supply means 72, the drainage means 9, etc., and performs soaking, washing, rinsing, etc. It controls each process such as dehydration to operate automatically.

The operation of the above configuration will be described. In FIG. 2, when the pre-washing process is started, the control means 11 first determines the amount of laundry using the cloth amount detection means 5 in step 12. Next, in step 13.14, the amount of cloth is classified into three levels: less than 1.5 kg, 1.5'kCg or more, 3 to 9 or more, and 3 to 9 or more, and step 15.16,
Set 17 to low water level, medium water level, and high water level, respectively. Next, in step 18, it is determined by the water level detection means 7 whether or not the set water level 1 has been reached. If the set water level has not been reached, water is supplied at the set water level 1 in step 19.

With this water supply operation, a water level was obtained at which the cloth was sufficiently immersed in the detergent liquid according to the amount of cloth. Next, in step 2o, the control means 11 determines whether the time t1 for the detergent to be sufficiently dissolved in water has elapsed or not, and if the time has not elapsed, the detergent is stirred in step 21 to dissolve the detergent in the water.

When t1 minutes have elapsed, the process proceeds to step 22, where the initial degree of transparency (do) is input using the degree of dirt detection hand Pi8. Furthermore, in step 23, it is determined whether 12 minutes have passed, and if not, in step 24, the stirring is stopped for 3 minutes and stirring is continued for 1 minute at t2.
Repeat in minutes. This action causes the dirt on the cloth to gradually seep into the water.

When 12 minutes have elapsed, the process proceeds to step 26 and the water permeability (dl) is input again. The time chart of the permeability during this stirring operation looks like a third piece of meat, and in the case of heavy dirt such as oil stains, the permeability decreases at a constant rate, but
In the case of mud stains, the transmittance drops significantly at the beginning and then becomes almost constant. Utilizing this characteristic, the control means 11 controls the amount of change in transmittance (do) between tl and 12 in steps 26 and 27.
-dl) is divided into three levels: less than 1V, 1■ or more and less than 2V, and 2■ or more, and sets each 5FJA 1 samurai interval to 16 minutes, 10 minutes, and 5 minutes at 29.30. A6 ・\7 Ru. Next, in step 31, it is determined whether the total time for soaking and washing has elapsed, and if it has not elapsed, step 32
Then, stop for 3 minutes and repeat stirring for 1 minute.

If it has passed, proceed to the next washing process in step 33,
In step 34, the stirring wJ operation in the rinsing process is performed at 1, when the washing time set in steps 28, 29, and 30 has elapsed, and the process proceeds to the tearing process.

According to the above embodiment, the water level is set according to the amount of laundry, and the degree of dirt in one column is determined by the amount of water permeability after a certain time, and the subsequent washing time is determined according to the degree of dirt. can be set.

Effects of the Invention As is clear from the above-mentioned embodiments, according to the present invention, the dirt level detection means detects the dirt level of the washing tub during the soaking process. You can fully soak it in the detergent solution and set the optimal soaking time.
