Description

Technical Field:

[0001] The present invention relates to a control method for improving the utilization rate of detergent and thus the washing ratio of a washing machine, which belongs to the technical field of washing machines. Background Art:

[0002] With the increasing global warming and resource consumption, today's consumers have an increasingly strong demand for low power consumption and the ability to wash clothes clean. The traditional method of dealing with washing machines is to directly introduce a large amount of water, then completely immerse the clothes in the washing tub, and then heat the temperature of the clothes and water in the tub to a very high level, and achieve the purpose of cleaning through long-term washing and high temperature. The treatment method of traditional washing machines may damage the fibers in the clothes or the ornaments on the clothes, and has relatively high energy consumption and water consumption.

[0003] Therefore, it is necessary to improve the existing technology to solve the deficiencies of the existing technology. Summary of the Invention:

[0004] The present invention provides a control method for improving the utilization rate of detergent and thus the washing ratio of a washing machine to solve the problems existing in the above-mentioned prior art. It can accurately perform intelligent control for clothes of different weight segments (large, medium, and small). During the washing process, through the control of water consumption, heating time, and different rotation speeds of the drum, a relatively high washing ratio can be achieved with the minimum water consumption and energy consumption.

[0005] The technical solution adopted by the present invention is as follows: A control method for improving the utilization rate of detergent and thus the washing ratio of a washing machine, and the specific steps are as follows:

[0006] Step 1: The program starts.

[0007] Step 2: After the user selects and enters the "energy-saving" mode through the button, the mode takes effect.

[0008] Step 3: The motor rotates, and the load is intelligently determined. Different load segments are determined through different dry cloth weights, and then different washing programs are executed.

[0009] Step 4: Activate the pre-wash valve. After the pre-wash valve fills water for 60 s, the main wash valve fills water once to 2400 HZ.

[0010] Step 5: After water inlet, the clothes are soaked for 8 min, and at the same time, a water replenishment operation is performed. The motor executes an operation of 50 rpm / min, rotating for 30 s and stopping for 8 s, so that the laundry detergent water and the clothes are fully soaked.

[0011] Step 6: Perform a water replenishment determination before heating. If the water level is higher than 2410 HZ, then water replenishment is performed until the set water level value of 2400 HZ is reached. After reaching the target water level, the heater is heated.

[0012] Step 7: Enter variable-speed washing. Control the motor speed at 45 prm for 3 s. The load adjusts its state. After it meets the requirements, the motor increases the speed to 93 rpm. The computer board reads the out-of-balance (OOB) value of the washing machine. If the OOB value meets the set value of 140 or less, the motor further increases the speed to 150 rpm to quickly generate foam and soak the load. After 1 min, the motor returns to 50 rpm / min, runs for 8 s and stops for 8 s, and washes back and forth twice.

[0013] Step 8: After variable-speed washing ends, determine whether to continue water replenishment according to different load segments. When water replenishment is required, first determine the water level. If the water level is higher than 2370 HZ, then perform water replenishment until the set water level value of 2360 HZ is reached.

[0014] Step 9: After the aforementioned washing duration is completed, enter the dehydration operation. The drain pump drains water for 1 min.

[0015] Step 10: Enter the rinsing operation and execute different rinsing programs according to different load segments.

[0016] Step 11: Enter the dehydration operation and drain water for 1 min.

[0017] Step 12: Before main dehydration, the computer board reads the out-of-balance (OOB) value of the washing machine and determines whether it meets the set speed condition.

[0018] Step 13: When the number of attempts is greater than 41 times and still does not meet the preset out-of-balance (OOB) value, UB alarm is issued.

[0019] Step 14: When the set speed condition is met in Step 12, determine whether the water level is higher than the defoaming water level of 2470 HZ.

[0020] Step 15: When the water level is higher than the defoaming water level of 2470 HZ, perform the defoaming operation. If the water level is lower than the defoaming water level of 2470 HZ, enter the final dehydration to reach the set target maximum speed.

[0021] Step 16: The clothes are loosened for 1 min. The motor runs at 35 rpm / min, runs for 8 s and stops for 8 s.

[0022] Step 17: End the entire control process.

[0023] Further, in Step 5, water is replenished into the outer tub through the replenishment water level. The water level sensor monitors the water level value. If the water level is higher than 2465 HZ, then perform water replenishment until the set water level value of 2455 HZ is reached.

[0024] Further, in Step 6, heat for different times according to different load segments. Among them, no heating is performed for 1 / 4 load, the heating time for half load is controlled within 5 min, and the heating time for full load is controlled within 20 min.

[0025] Further, in step eight, when determining whether to continue water replenishment, if it is fully loaded, water replenishment is required. If it is 1 / 4 loaded or half loaded, water replenishment is not required.

[0026] Further, in step ten, in the rinsing program, it is rinsed once for 1 / 4 load for 3 minutes, rinsed twice for half load with times of 6 minutes / 3 minutes respectively, and rinsed twice for full load with times of 10 minutes / 6 minutes respectively.

[0027] The present invention has the following beneficial effects: The present invention can precisely perform intelligent control for clothes of different weight segments of large, medium and small sizes. During the washing process, through the control of water consumption, heating time, and different rotation speeds of the drum, a higher washing ratio can be achieved with the minimum water and energy consumption. Specific embodiments:

[0028] The control method for improving the detergent utilization rate and thus the washing ratio of the washing machine of the present invention is as follows:

[0029] Step one: The program starts.

[0030] Step two: After the user selects and enters the "energy-saving" mode through the button, the mode takes effect.

[0031] Step three: The motor rotates, and the load is intelligently determined. Different load segments are determined through different dry cloth weights, and then different washing programs are executed.

[0032] Step four: Activate the pre-wash valve. After the pre-wash valve fills with water for 60 seconds, the main wash valve fills with water once to 2400 HZ.

[0033] Step five: After water inlet, the clothes are soaked for 8 minutes, and at the same time, the water replenishment action is executed. The motor executes the action of 50 rpm / min, rotating for 30 seconds / stopping for 8 seconds, so that the laundry detergent water and the clothes are fully wetted, and the water absorbed by the clothes can also increase the washing time and the washing ratio. Then, water is replenished into the outer tub through the water replenishment water level. The water level sensor monitors the water level value. If the water level is higher than 2465 HZ, water replenishment is carried out until the set water level value of 2455 HZ is reached.

[0034] Step six: Before heating, water replenishment determination is carried out. If the water level is higher than 2410 HZ, water replenishment is carried out until the set water level value of 2400 HZ is reached. After reaching the target water level, the heater is heated, and different heating times are set according to different load segments to increase the temperature in the tub, increase the activity of the detergent, and thus improve the washing ratio. Among them, due to the small load of 1 / 4 load and half load, the 1 / 4 load is not heated, the heating time for half load is controlled within 5 minutes, and the heating time for full load is controlled within 20 minutes.

[0035] Step 7: Enter variable-speed washing. Control the motor speed at 45 prm for 3 s. The load adjusts its state. After it meets the requirements, the motor increases the speed to 93 rpm. The computer board reads the out-of-balance (OOB) value of the washing machine. If the OOB value meets the set value of 140 or below, the motor further increases the speed to 150 rpm to quickly generate foam and soak the load. After 1 min, the motor returns to 50 rpm / min, runs for 8 s and stops for 8 s, and washes back and forth twice.

[0036] Step 8: After variable-speed washing ends, determine whether to continue water replenishment according to different load levels. If it is a full load, water replenishment is required. If it is a 1 / 4 load or a half load, no water replenishment is needed. When water replenishment is required, first determine the water level. If the water level is higher than 2370 HZ, water replenishment is carried out until the set water level value of 2360 HZ is reached.

[0037] Step 9: After completing the aforementioned washing duration, enter the dehydration operation. The drain pump drains water for 1 min.

[0038] Step 10: Enter the rinsing operation. Execute different rinsing programs according to different load levels. For a 1 / 4 load, rinse once for 3 min. For a half load, rinse twice, with times of 6 min / 3 min respectively. For a full load, rinse twice, with times of 10 min / 6 min respectively.

[0039] Step 11: Enter the dehydration operation. Drain water for 1 min.

[0040] Step 12: Before main dehydration, the computer board reads the out-of-balance (OOB) value of the washing machine and determines whether it meets the set speed condition.

[0041] Step 13: When the number of attempts is greater than 41 times and still does not meet the preset out-of-balance (OOB) value, UB alarm is triggered.

[0042] Step 14: When the set speed condition is met in Step 12, determine whether the water level is higher than the defoaming water level of 2470 HZ.

[0043] Step 15: When the water level is higher than the defoaming water level of 2470 HZ, defoaming operation is carried out. If the water level is lower than the defoaming water level of 2470 HZ, enter final dehydration to reach the set target maximum speed.

[0044] Step 16: Shake the clothes loose for 1 min. The motor runs at 35 rpm / min, runs for 8 s and stops for 8 s.

[0045] Step 17: End the entire control process.

[0046] The present invention can precisely perform intelligent control on clothes of various weight segments, large, medium and small. During the washing process, through the control of water consumption, heating time, and different rotational speeds of the drum, a high washing ratio can be achieved with the minimum water and energy consumption.

[0047] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, several improvements can be made without departing from the principle of the present invention, and these improvements should also be regarded as the protection scope of the present invention.
