Here, the standard concentration is defined as 20 grams of washing powder/30 liters of washing water.

Step S114

In the state where the washing and drying tub 2 is stationary, the electric circulation pump 26 is operated while the rotating disk 4 is rotated forward and reverse, and the washing water (high-concentration washing liquid) at the bottom of the outer tub 5 passes through the exhaust and drain port 5b The bellows 23 and internal piping 24 absorb water, and spray it out from the sprinkling port 16 through the internal piping 28 , bellows 29 , and lint filter 31 and spray it onto the laundry on the rotary table 4 to perform prewashing for circulation. The forward and reverse time (forward rotation time, stop time, reverse rotation time) or washing time of the rotary disk 4 in this prewashing is set according to the weight of the previously detected laundry or the set washing process.

Step S115

Since a part of the washing water sprinkled on the laundry during pre-washing is absorbed by the laundry, the amount of washing water accumulated at the bottom of the outer tub 5 is reduced. The amount of water to be reduced varies depending on the amount of laundry and the quality of the fabric, but the texture of the fabric has a great influence. Since the amount of clothes has been detected, after the pre-washing is completed, the water level is detected with reference to the detection signal output by the water level detection sensor 22, and the water reduction is obtained based on the detected water level, so that the water reduction is detected (estimated) according to the water reduction. Cloth texture. Then, with reference to the detection signal output from the water level detection sensor 22, the washing water supply electromagnetic valve 44a is controlled to open and replenish water to a predetermined water level h. The replenishment volume is generally about 20 liters.

Step S116

Start the normal wash as above for the prewash. The forward and reverse time (forward rotation time, stop time, reverse time) or washing time of the rotating disk 4 of the positive washing is set according to the previously detected laundry cloth amount or the set washing process. In addition, the replenishment of water in the above-mentioned step S115 may be performed an appropriate number of times during the normal washing as needed. The detergent concentration of the washing water after replenishment is about 2 to 3 times of the standard concentration.

Step S117

After the set positive washing is finished, the washing water is drained and spin-dried. The washing water is drained by opening the drain solenoid valve 25 so that the washing water in the outer tub 5 passes through the bellows 23 from the exhaust and drain port 5b. The piping 24 and the drain solenoid valve 25 flow out to the external drain hose 27 . In addition, the washing water is spin-dried by controlling the washing-drying drive unit 7 to rotate the washing and spinning-drying tub 2 together with the rotary disk 4 at a high speed in one direction. Washing and spin-drying tub 2 and rotating disk 4 rotational speeds during this washing water spin-drying are set to be the same as the rotating speed (about 1000rpm) when final spin-drying described later, to realize high dehydration rate (about 60%) .

Step S118

Implement water supply for the first rinse. This rinsing water supply is to close the drainage solenoid valve 25, open the rinsing water supply solenoid valve 44b and tap water or operate the bathtub water suction pump 44c to discharge the leftover water from the shower from the sprinkling port 16 and sprinkle it on the washing on the rotating disk 4. The amount of water supplied for rinsing at this time is about 25 liters (the same water level).

Step S119

Carry out the first rinse water cycle rinse. This cycle rinsing is the same as the normal washing. In the state where the washing and drying tub 2 is stationary, the electric circulation pump 26 is operated while the rotating disk 4 is rotating forward and backward to suck in the rinsing water at the bottom of the outer tub 5 and discharge it from the water spout 16. Sprinkle on the laundry on the rotating disk 4 to perform circulation. The rotating disc 4 forward and reverse time (forward rotation time, stop time, reverse time) or rinse time during this cycle rinsing is set according to the amount of laundry, cloth texture or set washing process.

Step S120

Drain and spin dry the first rinse. The rinsing water is drained by opening the drain solenoid valve 25 . In addition, the rinsing water spin-drying is the same as the washing water spin-drying, by controlling the washing spin-drying driving device 7 to make the washing and spinning-drying tub 2 and the rotary disk 4 rotate at a high speed in one direction. Washing and spin-drying bucket 2 and rotating disk 4 rotational speeds when this washing water is spin-dried are set to be the same as the rotational speed when final spin-drying described later, to realize high dehydration rate (about 60%).

Step S121

Carry out the 2nd rinse water supply. This rinsing water supply is the same as carrying out the 1st time rinsing water supply, is to close the drain solenoid valve 25, open the rinsing water supply solenoid valve 44b to spray tap water from the sprinkling port 16 and sprinkle it on the laundry on the rotary disk 4. The amount of water supplied for rinsing at this time is about 25 liters (the same water level).

Step S122

Perform the second rinse water cycle rinse. This cycle rinsing is also the same as the normal washing. In the state where the washing and drying tub 2 is stationary, the electric circulation pump 26 is operated while the rotating disk 4 is rotating forward and backward to suck the rinse water at the bottom of the outer tub 5 and spray it out from the spout 16. And be sprinkled on the washing on the rotating disk 4 and carry out circulation. The rotating disc 4 forward and reverse time (forward rotation time, stop time, reverse time) or rinse time during this cycle rinsing is set according to the amount of laundry, cloth texture or set washing process.

Step S123

Implement the second rinse water drainage. This rinsing water drain is performed by opening the drain solenoid valve 25 .

Step S124

Carry out final spin-drying treatment. Finally spin dry, be under this state of opening drain electromagnetic valve 25, run washing and spin dry driving device 7 to make washing and spin-drying tub 2 carry out high-speed rotation of about 1000rpm to one direction together with rotating disk 4, to wash and spin dry simultaneously. The laundry in the drying bucket 2 is centrifugally spin-dried. The time required for this final spin-drying is the time for obtaining the desired dehydration rate.

Step S125

Drying is carried out. This drying is in the state of opening the drain electromagnetic valve 25, and the air in the outer tub 5 is sucked out from the drain and exhaust port 5b through the bellows 33 to the water cooling by running the electric blower 37 located in the middle of the water cooling dehumidification air duct 34. In the dehumidification air passage 34, when passing through the ascending air passage 34a of the water-cooling and dehumidifying air passage 34, it is in contact with the water-cooling and dehumidifying plate 35 arranged in the ascending air passage 34a and the cooling water falling onto the surface of the water-cooling and dehumidifying plate 35. After being dehumidified, it passes through the lint filter screen 36 and collects the lint. After being heated by the PTC electric heater 41 in the air heating pipe 39, it is sent to the air injection port 17 through the bellows 40 and blows from the air injection port 17. Put into washing and spin-drying bucket 2 simultaneously.

The cooling water flowing down the water-cooled dehumidification plate 35 is supplied with tap water by opening the cooling water supply electromagnetic valve 44d, and the cooling water flowing down the water-cooled dehumidification plate 35 passes through the drain and exhaust port 5b, the bellows 23, the internal piping 24, and the drain. Solenoid valve 25 flows to external drain hose 27 and out.

This drying control is performed while monitoring the detection signal output from the humidity sensor 38 that senses the humidity of the air after water cooling and dehumidification, and ends when the humidity falls below a predetermined value.

Step S126

While waiting in the power consumption state, the automatic power OFF waiting control included in the next control processing is executed. The display panel 11b of the operation display panel unit 11 is in a state of being turned off as it is.

Step S204

The presence or absence of an instruction input signal from the cover opening/closing instruction switch 13 is monitored during the automatic power OFF standby control.

Step S205

When an instruction input signal from the cover opening/closing instruction switch 13 is input, detection signals from the cover fully open detection sensor 46 and the cover fully closed detection sensor 47 are confirmed.

Step S206

The outer cover opening and closing drive control process is performed based on the detection signals from the outer cover full opening detection sensor 46 and the outer cover full closing detection sensor 47 . When the full-open detection signal is output from the cover full-open detection sensor 46, the open-close drive motor 10f is controlled to carry out the cover-closing drive to completely close the cover 10, and when the full-close detection signal is output from the cover full-close detection sensor 47, the cover 10 is fully closed. When the signal is signaled, the opening and closing drive motor 10f is controlled to drive the opening and closing of the outer cover to fully open the outer cover 10 .

Step S207

After the predetermined time of the automatic power OFF waiting control has elapsed, the power self-protection relay 45d is turned on to execute the automatic power OFF control of cutting off the power, and it is in a standby state without power consumption.
