The present invention relates to a washing method for a washing machine for washing foreign matter such as black mold generated in the washing machine.

Conventionally, the washing machine was comprised as shown in FIG. The configuration will be described below.

As shown in FIG. 6, the outer tub 1 includes a washing tub 3 rotatably arranged with a stirring blade 2 at the bottom thereof, and is suspended from the washing machine outer frame 5 by the suspension rod 4. have. The motor 6 drives the stirring blade 2 and the washing tank 3 via the V belt 7 and the clutch 8 as the reduction mechanism. The water supply valve 9 supplies water in the washing tank 3, the drain valve 10 drains the washing water in the washing tank 3, and the water level detecting means 11 detects the water level in the outer tank 1. .

The pump chamber 13 is formed in the outer periphery of the inner blade 12 of the stirring blade 2, and the wash water in the washing tank 3 is passed through the circulating water path 14 from the pump chamber 13 via the circulation filter ( Water in 15). The cover body 16 is provided in the upper part of the outer tank 1, and the control apparatus 17 controls the motor 6, the water supply valve 9, the drain valve 10, etc., and wash | cleans, rinses, and dewaters each. It is to control the administration gradually.

When washing is performed by the washing machine of the above configuration, a part of the contaminant and the detergent component from the laundry are combined with metal ions in the tap water to produce metal soap, and the outer tank 1, the washing tank 3, and the stirring blade ( 2) attached to the back. When washing is repeated, the microorganisms contained in the laundry act on the attached metal soap, so that hidden parts such as the outer wall of the washing tank 3, the inner wall of the outer tank 1, the back surface of the stirring blade 2, etc. Foreign materials such as biofilm and black mold are generated, and the deposits of these foreign matters are sometimes removed by washing water streams and contaminate the laundry.

As a method of removing this foreign matter, there is a washing tank cleaner mainly composed of a bleaching component, but the method of using the water is to operate the water supply valve 9 and the water level detecting means 11 to supply water to the water level as high as possible in the washing tank 3. After that, the cleaning agent is added, the stirring blade 2 is rotated, the cleaning agent is dissolved, and the cleaning agent is soaked for several hours. The cleaning agent is applied to the foreign material to remove the foreign matter, and the drain valve 10 is operated to drain the liquid. )do. Then, in order to rinse the washing tank 3, it is common to supply water in the washing tank 3 to a predetermined water level, to rinse by rotating the stirring blade 2, and to drain after that.

However, this method is very cumbersome because the long-time immersion stroke, which is a washing stroke, is performed manually, and the rinsing stroke is then automatically performed. There was a problem that only foreign matters in the submerged portion could be removed, and foreign matters generated above the water level of the water level fluctuation generated by the rotation of the stirring blade 2 could not be removed. In addition, since the foreign matter once removed cannot be sufficiently discharged and recovered by the rinsing stroke, it remains in the washing machine, and there is a problem that it adheres to the laundry and contaminates it at the next washing.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to enable automatic washing and rinsing strokes having a long immersion stroke and to remove foreign substances generated in the washing machine.

The present invention provides a washing process for washing the washing tank and the stirring blade disposed rotatably at the bottom of the washing tank and the outer tank containing the washing tank with a washing liquid containing a cleaning agent, and the washed washing tank, outer tub and stirring blade for achieving the above object. It has a rinsing stroke to rinse, and the washing stroke performs a stroke for making the washing liquid of a predetermined concentration in the washing tank and the outer tank, and a immersion stroke with an intermittent reverse rotation of the stirring blade, and subsequently drains the washing liquid in the washing tank in this order. A washing method of a washing machine to be executed was provided.

Hereinafter, the Example of this invention is described, referring FIGS. In addition, the same thing as the conventional example shown in FIG. 6 attaches | subjects the same code | symbol, and abbreviate | omits description.

Example 1

As shown in FIG. 1, the control device 18 controls operations of the motor 6, the water supply valve 9, the drain valve 10, and the like to gradually control washing, rinsing, and dehydration strokes. Control one or more laundry laundry strokes. Moreover, the control apparatus 18 performs the washing | cleaning stroke which wash | cleans with the washing | cleaning liquid containing a washing | cleaning agent, and the rinsing | stroke process after this washing | cleaning stroke, and the stirring blade arrange | positioned rotatably at the bottom of the washing tank 3 and this washing tank 3 is carried out. (2) and the inside of the outer tank 1 containing this are cleaned.

The washing stroke performs the washing liquid preparation stroke for making the washing liquid of a predetermined concentration in the washing tank 3 and the outer tank 1, and the immersion stroke with the intermittent reverse rotation of the stirring blade 2, and then in the washing tank 3 A rinsing stroke with a drain stroke of the cleaning liquid is performed in this order.

Here, in the immersion stroke, the water level is set to the predetermined water level P1 higher than the maximum water level at the time of washing the laundry, and the reverse rotation and the rotation stop of the stirring blade 2 are alternately executed. After the immersion stroke, the stirring stroke 2 is performed to stir the washing liquid in the washing tank 3.

The operation will be described with reference to FIGS. 1 and 2 in the above configuration. When the start switch (not shown) is pressed in step 20, it enters the washing liquid preparation stroke of the washing stroke, and in step 21, the maximum at the time of washing the laundry in the washing tank 3 by the water supply valve 9 and the water level detecting means 11. Water is supplied to a predetermined water level P1 higher than the water level, and the operation of the water supply valve 9 is stopped. In step 22, the cleaning agent is added, and in step 23, the stirring blade 2 is rotated by the motor 6 for a predetermined time, dissolving the cleaning agent, and a washing liquid having a uniform concentration is prepared.

Subsequently, it enters the immersion stroke accompanying the intermittent reverse rotation of the stirring blade 2, and in step 24, the stirring blade 2 is rotated left and right by on / off control by the motor 6. The left and right reverse rotation of the stirring blade 2 increases the force for stirring the washing liquid of the washing tank 3, and when the stirring blade 2 is in an on state, the surface of the water in the washing tank 3 descends at the center, The water surface between the washing tank 3 and the outer tank 1 rises.

At this time, the water surface between the washing tub 3 and the outer tub 1 slightly rises above the predetermined water level P1, and the washing agent evenly spreads on the outer wall of the washing tub 3 and the inner wall of the outer tub 1. On the contrary, when it is in an off state, the water surface in the washing tank 3 returns, and the water surface between the washing tank 3 and the outer tank 1 falls slightly.

Thereafter, in step 25, the immersion for stopping the reverse rotation of the stirring blade 2 during the immersion stroke is performed for a predetermined time, and the cleaning liquid is sufficiently applied to the foreign material. In step 26, by repeating the operation of step 24 and the operation of step 25 a predetermined number of times, the cleaning agent is spread evenly, and foreign matter is removed by the water flow formed by the reverse rotation of the stirring blade 2.

In the subsequent stirring stroke, in step 27, the stirring blade 2 is reversely rotated, and the washing liquid in the washing / drying dehydration tank 3 is passed through the circulation water passage 14 from the pump chamber 13 to form a yarn filter filter ( 15), and the foreign matter contained in the cleaning liquid is recovered to the real filter filter 15. At this time, the foreign matter deposited on the back surface of the stirring blade 2, the circulation channel 14, etc. can be removed by the washing | cleaning liquid at the same time, and it can collect | recover by the filter filter 15.

Subsequently, it enters the drain stroke, and the drain valve 10 is operated in step 28 to drain the washing liquid in the washing tank 3, and then the flow shifts to the rinsing stroke in step 29.

In this way, water flow is generated by intermittently inverting and rotating the stirring blade 2 by the immersion stroke, and more foreign matters generated on the outer wall of the washing tank 3 and the inner wall of the outer tank 1 can be removed and automated. The cumbersome stroke can be easily performed, and foreign substances generated in the washing machine can be removed.

Further, in the immersion stroke, the water level is higher than the maximum level at the time of washing the laundry, and the reverse rotation and the rotation stop of the stirring blade 2 are alternately performed to stir the washing liquid to lower the water surface center portion of the washing tank 3. At the same time, since the water level between the washing tank 3 and the outer tank 1 rises, the washing liquid is also applied to the foreign matter generated on the outer wall of the upper washing tank 3 and the inner wall of the outer tank 1 than the maximum water level during washing. It can be removed and can be removed to a high side.

In addition, after the immersion stroke, the stirring stroke which agitates the washing | cleaning liquid in the washing tank 3 by the stirring blade 2 is carried out, and the foreign material removed by the immersion stroke is rotated by the stirring blade 2, and the filter filter 15 is carried out. Can be recovered within

In addition, in the present embodiment, the level of the washing liquid preparation stroke and the level of the immersion stroke are the same, but the level of the washing liquid preparation stroke is, for example, the maximum level at the time of washing the laundry, and when the laundry is washed. The water supply may be further supplied up to a water level higher than the maximum water level. In this case, the cleaning agent can be dissolved in a short time by the cleaning liquid preparation stroke.

Example 2

As shown in FIG. 3, the control device 29 controls operations of the motor 6, the water supply valve 9, the drain valve 10, and the like to gradually control washing, rinsing, and dehydration strokes. The washing stroke which washes with the washing | cleaning liquid containing a washing | cleaning agent, and a rinsing stroke after that is performed to wash | clean the washing tank 3 and the inside of the outer tank 1 which contained this washing tank 3, and a rinse stroke is carried out with the water supply valve 9 A bath rotation rinse stroke for simultaneously opening the drain valve 10 and rotating the washing tank 3 at low speed; a first stirring rinse stroke for closing the drain valve 10 and stirring the stirring blade 2 with a small amount of water; The second stirring rinsing stroke for stirring the stirring blade at the level of the stroke, and the drain valve 10 are opened to perform the drain stroke at least once in this order.

In addition, the water rinsing is performed before the draining stroke of the rinsing stroke. The other structure is the same as that of Example 1, the same code | symbol is attached, and description is abbreviate | omitted.

The operation will be described with reference to FIGS. 3 and 4 in the above configuration. After the end of the washing stroke, it enters the rinsing stroke, and in step 31, performs the tank rotation rinse stroke which rotates the washing tank 3 at low speed while operating the water supply valve 9 and the drain valve 10 simultaneously, and after completion of the washing stroke (2) The foreign substances remaining on the top and bottom of the outer wall of the washing tank 3 and the bottom of the inner wall of the outer tank 1 are discharged together with the drainage. At this time, the water supply valve 9 and the drain valve 10 may be operated in place of the crude rotation rinse stroke, and the water supply and drainage stroke may be performed without rotating the washing tank 3 and executing water supply and drainage at about the same time. Do.

Next, in step 32, the drain valve 10 is closed, the water supply valve 9 and the water level detecting means 11 are supplied to the small amount of water level P2, and in step 33 the stirring blade ( The 1st stirring rinse stroke which rotates 2) by reverse rotation for a predetermined time can be performed, and the foreign material which remains between the washing tank 3 and the outer tank 1 can be spread | diffused in a washing | cleaning liquid. At this time, since the stirring blade 2 is reversely rotated by a small amount of water, strong water flow is generated, and the removed foreign matter is pulverized finely.

Next, in step 34, the water level P1 of the immersion stroke of the washing stroke is higher than the first stirring rinse stroke by the water supply valve 9 and the water level detecting means 11 in a state where the drain valve 10 is closed. Water is supplied to the washing tank 3 and the washing tank 3 and the outer tank 1 above the small amount water level P2 are executed by performing the second stirring rinsing stroke in which the stirring blade 2 is reversed and rotated by the motor 6 at a predetermined time in step 35. The foreign matter remaining in between is washed away and diffused into the cleaning liquid.

Here, since the stirring blade 2 is rotated for a predetermined time, the washing liquid in the washing-and-drying dewatering tank 3 is delivered from the pump chamber 13 via the circulation water passage 14 to the room filter cartridge 15. Since the foreign matter is finely pulverized in step 33, the foreign matter is introduced into the silbomura filter 15 together with the water, and is recovered from the silbomura filter 15. In addition, since the stirring blade 2 is reversely rotated by the high water level P1 at this time, the quantity of the water which passes through the real bovine filter 15 is large, and foreign material is easy to collect | recover.

Next, while operating the water supply valve 9 and the drain valve 10 in step 36, the stirring blade 2 is rotated and water rinsing is performed. Until the previous stroke, foreign matter which could not be discharged or recovered can be discharged with drainage. In step 37, the water supply valve 9 is closed and the drain valve 10 is operated to drain the water in the outer tank 1. The operation of the water supply valve 9 and the drain valve 10 in the water rinsing may be a continuous operation or an intermittent operation, respectively.

Thus, the stirring blade 2 is performed by performing the tank rotation rinse stroke which rotates the washing tank 3 at low speed, operating the water supply valve 9 and the drain valve 10 simultaneously after a washing stroke and before a 1st stirring rinse stroke. Since foreign substances remaining on the top and bottom of the outer wall bottom of the washing tank 3 and the bottom of the inner wall of the outer tank 1 can be discharged out of the outer tank 1 by draining at the same time as water supply, subsequent rinsing strokes can be efficiently executed. .

At this time, instead of the crude rotation rinse stroke, the water supply valve 9 and the drain valve 10 are operated so that even if the water supply and drainage stroke which performs the water supply and the drainage is performed at the same time without rotating the washing tank 3, The working effect can be obtained.

In addition, in the first stirring rinsing stroke, since the stirring blade 2 is reversely rotated by a small amount of water, strong water flow is generated, and the removed foreign matter is finely pulverized, diffused in the washing liquid, and moved out of the outer tank 1. Then, water is supplied to the water level P1 of the immersion stroke, and the stirring blade 2 is inverted and rotated for a predetermined time to remain between the washing tank 3 and the outer tank 1 above the small water level P2. At the same time as the foreign matter is washed off, it is diffused into the cleaning liquid, and the amount of water passing through the silkworm filter 15 can be increased, and the foreign matter can be collected in the yarn filter filter 15.

In addition, by performing the rinse of water, the foreign matter which could not be recovered and discharged in the washing stroke and the rinsing stroke can be discharged, so that foreign matters remain in the washing machine.

In the present embodiment, the rough water rinsing stroke or the water supply and drain stroke executed in place of the rough water rinsing stroke is performed before the first stirring rinsing stroke, but it is important that the foreign matter is well discharged out of the outer tank 1. It is a target, and the same effect can be obtained even if it is performed before or after a 2nd stirring rinse stroke.

In addition, in this embodiment, although the water rinsing is performed after the 2nd stirring rinse stroke, water rinsing may be performed instead of the 2nd stirring rinse stroke, and the same effect can be acquired.

In addition, in the present embodiment, when the rinse water is rinsed, the water supply valve 9 and the drain valve 10 are operated to drain while supplying water, but only the water supply valve 9 is operated without operating the drain valve 10, Similar effects can be obtained even if the drainage is performed from an overflow outlet (not shown).

The washing step of washing with a washing liquid containing a washing agent and a rinsing step thereafter are performed to clean the washing tank 3 and the inside of the outer tank 1 containing the washing tank 3, and the rinsing step is a small amount of immersion line information. The first stirring rinse stroke for stirring the stirring blade 2 with water of water and the second stirring rinse stroke with the water level P3 above the water level P1 of the immersion stroke of the washing stroke are performed, and then the drainage stroke is performed sequentially. Do it. The other structure is the same as that of Example 2, the same code | symbol is attached, and description is abbreviate | omitted.

The operation in the above configuration will be described. In the first stirring rinsing stroke, since the stirring blade 2 is reversely rotated by a small amount of water, strong water flow is generated, and the removed foreign matter is finely pulverized, diffused in the washing liquid, and easily moved out of the outer tank 1. .

Next, water is supplied to the water level P3 higher than the water level P1 of the immersion stroke of the washing stroke, and the stirring blade 2 is inverted for a predetermined time to rotate the washing tank at a position higher than the small water level P2 ( The foreign matter remaining between 3) and the outer tank 1 is washed off and diffused into the washing liquid. Further, the amount of water passing through the real bombardment filter 15 can be made larger than that at the level P1 of the immersion stroke, and more foreign matter can be recovered in the actual keyhole filter 15.

In addition, by making the water level higher than the water level P1 of the immersion stroke, it is possible to rinse the upper part of the washing tank 3 and the outer tank 1 to which the cleaning liquid is attached by the flow of the immersion stroke.
