(1st embodiment)

As shown in FIG. 1, the outer tub 14 has the washing | cleaning and dehydration tank 15 arrange | positioned so that it may rotate, and hangs down to the washing machine outer frame 17 by the hanger rod 16. As shown in FIG. The motor 18 rotationally drives the stirring blade 21 provided in the inner bottom of the washing-and-dehydrating tank 15 and the washing-and-dehydrating tank 15 via the V belt 19 and the deceleration mechanism 20.

The cover body 22 is provided in the upper part of the outer tub 14, and forms the bubble discharge part 23. As shown in FIG. The bubble discharge section 23 has an opening in the washing and dewatering tank 15 inward direction. A portion of the outer tub 14 is divided to form a long passage 24 in the longitudinal direction. The bottom of the passage 24 communicates with the inner bottom of the outer tub 14, and the upper portion of the passage 24 communicates with the foam discharge portion 23 formed in the cover body 22. At the bottom of the passage 24, a porous body 25 communicating with the pump 27 by a hose 26 is provided. The bubble generator of Embodiment 1 is comprised from the hose 26, the pump 27, and the porous body 25. As shown in FIG.

The water supply valve 28 supplies water in the washing and dewatering tank 15, and the drain valve 29 drains the washing water in the outer tank 14.

The control apparatus 30 has the same structure as the broken line portion shown in FIG. 2. The control means 31 is a microcomputer, which controls the operations of the motor 18, the pump 27, the water supply valve 28, the drain valve 29, etc. through the power switching means 32, and washes, rinses, A series of processes such as dehydration are controlled sequentially. The input setting means 33 sets a driving course and the like. The control means 31 inputs the information from the input setting means 33, and displays it on the display means 34 on the basis of the information to inform the user. The storage means 35 stores data necessary for controlling by the control means 31. It also has a commercial power supply 36 and a power switch 37.

Next, operation | movement of the washing machine of Embodiment 1 is demonstrated. After the laundry and detergent are put into the washing and dewatering tank 15 and the operation is started, the control means 31 operates the water supply valve 28 to start water supply, and at the same time, the washing and dewatering tank 15 Start the rotation. The washing / dehydrating tank 15 rotates until the water level in the washing / dehydrating tank 15 reaches the set water level. When water is supplied while the washing and dewatering tank 15 is rotated in this manner, the detergent injected is dissolved in water by the stirring force generated by the rotation of the washing and dewatering tank 15.

When the set water level is reached, the operation of the water supply valve 28 is stopped, and the control means 31 operates the pump 27 to form a porous element in the wash water provided at the bottom of the passage 24. Air is sent to the 25 through the hose 26. As a result, as shown in FIG. 1, the air sent to the porous body 25 rises as a bubble when it comes out from the porous body 25, reaches a washing water surface, and produces | generates detergent foam. Detergent foam rises through the passage 24 and is poured from the foam discharge part 23 of the cover body 22 onto the laundry in the washing-and-dehydrating tank 15.

Thus, the washing | cleaning method which utilizes foam effectively is memorize | stored in the memory | storage means 35, and the control apparatus 30 controls each process of washing according to the stored method.

Here, the detergent foam will be described in detail. As shown in FIG. 3, when the detergent molecule 200 is modeled and shown, it is composed of a hydrophilic group 202 and a lipophilic group 204. Next, the state which melt | dissolved the detergent in water is shown in FIG. Detergent molecules 200 are aligned at the interface (water surface), and unclean detergent molecules are present in water or as micelles (groups), respectively. In addition, when the detergent molecules at the interface are removed, the detergent molecules in the water immediately move to the interface to replenish.

Therefore, for example, as shown in FIG. 5, when the bubble 210 is sent to the wash water, the bubble 210 rises to reach the interface, and the detergent molecules 200 aligned at the interface are directly bubbled. Foam 220 of the shape held as is generated. In other words, since the bubbles 220 arranged on the surface of the detergent molecules 200 as much as possible, bubbles with a high detergent concentration. At this time, the detergent molecules in the liquid move to the interface as replenishment of the detergent molecules removed as bubbles. Thus, when bubbles 210 are sent continuously, bubbles 220 are created in sequence. At this time, in this bubble film, the lipophilic group 204 is lined toward inner side to outer side.

By contacting the foam 220 thus formed with the surface of the contaminated clothing or through the clothing, the oil and particle contamination adhered to the oil are combined with the lipophilic 204 to be removed by the detergent. In addition, if the foam 220 is broken while passing through the garment, the result is that the washing water having a high detergent concentration penetrates the garment, and the contamination is likely to fall. In this way, the detergent of clothing is effectively performed.

In other words, wash water is used as a foam, and the foam is passed through the surface of the contaminated laundry or in the laundry to remove oil and particles attached to the oil, or when the foam breaks through the laundry, washing the laundry with high detergent concentration. By soaking the water, the cleaning power can be increased.

Moreover, since foaming increases the volume of wash water, a detergent component can be made to act on the contamination of laundry with little wash water. In addition, since the detergent foam is poured from the upper side of the laundry, the mechanical force on the washing-and-dehydrating tank 15 can be contaminated with the contamination of the laundry which is hard to be transmitted. Thus, the washing stain on the upper and lower sides of the washing tank can be reduced.
