As shown in FIG. 7, the nozzle case 15b is formed in a horizontally long lid shape whose upper surface is closed and whose lower surface is open. A cylindrical connecting portion 15g to which the hose 16 is connected is provided on the back side. The nozzle 15a was mounted on the opening at the lower surface.

In the nozzle 15a, the whole body is formed in a horizontally long saucer shape, and a water supply passage 15h is protruded from an inner bottom portion. This water supply channel 15h is formed in a gutter shape by a peripheral wall protruding from the inner bottom portion of the main body as shown in FIG.
The opening at the rear end communicates with the cylindrical connecting portion 15g, and a flat circular water conduit 15k is formed at the tip of the substantially linear water conduit 15j at the rear portion, and the center of the water conduit 15k is used for watering. A mist supply port 15i is formed.

In this case, the center of the planar circular water conduit 15k is eccentric so as not to be located on the linear extension of the substantially straight water conduit 15j, and is positioned on the back straight extension of the substantially straight water conduit 15j. Is positioned with respect to the substantially straight water conduit 15j so that the flat water conduit 15k is aligned with the tangent on the back side of the flat circular water passage 15k. The flow of water flowing into the water channel 15k is set to be counterclockwise (in the same direction as the rotation direction of the washing and dewatering tub 5).

The mist supply port 15i has an inlet portion formed in a funnel-like portion, and a lower sprinkling port connected thereto is formed in a divergent portion 15d. The diameter of the mist supply port 15i is The diameter of the water particles is set, for example, to a mist-like shape of 1.0 mm or less, and the normal water supply amount is 3 L / min.

The diameter of the narrow portion of 5i was set to about 3 mm.

The rear end of the nozzle 15a is inclined obliquely downward with respect to the nozzle case 15b, and the mist supply port 15i is obliquely provided so as to project obliquely toward the washing and dewatering tub 5. The length of the mist supply port 15i is set to, for example, about 3 to 7 mm so that the angle can be easily controlled so that the range falls within the washing and dewatering tub 5.

The injection range from the nozzle 15a can be made variable by appropriately setting the angle of formation of the mist supply port 15i as described above. For example, the injection range can be narrowed by separately attaching a horn or the like. Can also be done.

A horizontally long band-shaped nozzle cover 17 having an L-shaped cross section is attached to the front end of the nozzle case 15b at a position above the front part of the nozzle 15a. This nozzle cover 1
7 is formed of a transparent member so as to appeal to the user about the presence of the rear mist supply port 15i, and is colored in a color different from the color of the washing and dewatering tub 5 and the water supply case 11, which are separate members around the mist supply port 15i. .

In such a washing machine, as shown in the process diagram of FIG. 8, the entire process of water supply, washing, rinsing, and dehydration is automatically advanced by the operation of the control device. When the laundry is put in the washing machine, the amount of the laundry is measured by the load amount detecting means, and as a result of the measurement, the detergent amount is displayed.

Accordingly, the user puts the detergent into the washing / dewatering tub 5 with the indicated amount of detergent, and closes the lid 10 to wash the washing water from the water supply hose connected to the water supply port 12 and directly connected to the water tap. When the water is supplied to the dewatering tank 5 and the water level sensor (not shown) detects that the water has been supplied to the set water level, the water supply is stopped, the motor 6 is energized, and the rotating blades 4 are energized.
Rotates, and the washing process in which the laundry in the washing and dewatering tub 5 is stirred is started.

When the washing operation is performed for a set time,
After the washing process is completed, the washing water is drained from the drain hose 14, and the washing and dewatering tub 5 rotates together with the rotary blade 4 to be dehydrated, and the process proceeds to the next rinsing process. In the rinsing process, tap water is supplied to the mist supply device 15 as rinsing dehydration for the laundry in which the detergent after dehydration remains.
The washing and dewatering tub 5 is rotated while mist is supplied to the laundry in the washing and dewatering tub 5 by atomizing the water with the nozzle 15a.

Thus, the detergent adhering to the laundry is discharged to the outside of the washing and dewatering tub 5 by centrifugal force together with the mist-supplied moisture, so that the detergent does not adhere to the laundry again and the rinsing efficiency is improved. Enhance.

In this case, the water supplied from the mist supply device 15 is in the form of a mist as described above.
From the substantially straight water conduit 15j to the plane circular water conduit 15k
Flows through the peripheral wall of the planar circular water conduit 15k, and reaches the mist supply port 15i while scrolling in the funnel-shaped portion and the divergent portion in the counterclockwise direction. The direction of rotation of the dewatering tub 5 is opposite to that of the dewatering tub 5, and the mist supply water is not repelled when hitting the laundry, but is efficiently absorbed by the laundry,
Since the laundry inside is rotated by the rotation of the tub, the mist supply water hits the laundry evenly.

After rinsing and dewatering for a predetermined time, for example, 2 minutes, drainage and dehydration are performed, and the process proceeds to the next pool rinsing step. This pool rinse is set for the user who uses the finishing agent, and after the water is supplied to the washing and dewatering tub 5 to a predetermined water level, the rotating blade 4 is rotated for a predetermined time, for example, 2 minutes while the water is stored. Do it.

After the completion of the rinsing, the water is drained, and finally, the washing and dewatering tub 5 and the rotating blade 4 are rotated at a high speed.

[0020]

Since the water supplied in the water supply process is not in the form of a shower or a mist, it hits only one specific location on the laundry in the washing and dewatering tub. For this reason, if the detergent put into the washing and dewatering tub prior to water supply has adhered to the laundry, the area where the water supplied during the water supply process did not reach the laundry remains undissolved with the detergent attached. Will shift to the washing process.

In the washing process, the laundry is agitated and the top and bottom are switched in the washing and dewatering tub.
It takes three minutes, during which the detergent adhering to the laundry does not come into contact with water and remains undissolved, making it difficult to obtain the desired detergency. In particular, detergents on the swollen laundry containing air are hardly dissolved.

An object of the present invention is to provide a method for controlling the operation of a washing machine which can solve the disadvantages of the prior art, can surely dissolve the detergent in the initial stage of the washing process, and can obtain the initial washing ability. To provide.

A detergent dissolution step was included.

By supplying the mist in the washing process in this manner, the water in the tub can be evenly applied to the laundry in the tub by the water sprayed in the form of mist. Therefore, even if the detergent adheres to the surface of the laundry, the detergent is dissolved by the mist water supply, and the cleaning ability is improved.

Third, in the agitating process, the mist is supplied intermittently for a predetermined period of time at a predetermined time in the initial stage, so that the upper and lower parts of the laundry are exchanged in the washing and dewatering tub for washing. In synchronization with this, the remaining detergent can be efficiently dissolved.

In the detergent dissolving step, after water is supplied to a set water level in a preceding water supply step, mist is supplied for a predetermined time by a mist supply device at an initial stage of the washing step.
Then, following the detergent dissolving step, by performing a stirring step of stirring while mist is supplied by the mist supply device, the detergent adhering to the upper surface of the laundry in the first detergent dissolving step of the washing step can be spread over a wide range. Can be melted.

Fifth, following the detergent dissolving step, by performing a stirring step of stirring while supplying mist by the mist supply device, the detergent adheres to the upper surface of the laundry in the first detergent dissolving step of the washing step. It is possible to dissolve the existing detergent in a wide range, and thereafter, while replacing the upper and lower portions of the laundry in the washing and dewatering tub, the remaining detergent can be efficiently dissolved in synchronization with the washing.

Sixth, since the rinsing step includes a dehydration rinsing step for supplying mist water, not only can the washing step be performed efficiently, but also the detergent can be efficiently removed in the rinsing step, and the entire washing step can be performed. You can wash efficiently.
