Description

Operating method in washing machine

The present invention relates to a method of operating a laundry apparatus, and more particularly, to a washing operation method of the laundry apparatus.

In general, the washing apparatus is largely divided into a pulsator washing machine in which the drum stands vertically, and a drum washing machine in which the drum is laid down in the horizontal direction.

Here, since the drum washing machine is laid down in the horizontal direction as described above, the drum washing machine performs washing by dropping the laundry introduced into the drum.

1 and 2 schematically show a conventional structure of the aforementioned drum washing machine.

That is, the drum washing machine includes a main body 10, a tub 20 mounted in the main body 10, a drum 30 rotatably mounted in the tub 20, and the drum 30. It comprises a drive means for driving.

Here, an inlet 11 through which laundry is introduced is formed on the front surface of the main body 10, and a door 40 that opens and closes the inlet is mounted at a peripheral portion of the inlet 11.

In addition, the tub 20 is provided with dampers 21 at both bottoms of the outer circumferential surface thereof and is supported in the main body 10.

At this time, the inner bottom of the tub 20 is provided with a washing water heater 60 is configured to enable the temperature control of the washing water used for washing.

In addition, the drum 30 is rotatably mounted in the tub 20, and a plurality of through holes 31 for inflow / outflow of wash water are formed on the circumferential surface thereof as illustrated in FIG. 2. .

In addition, the driving means includes a drive motor 71 for driving the drum 30, and a belt 72 connected to transfer the driving force of the drive motor 71 to the drum 30.

In the conventional drum washing machine configured as described above, a washing stroke, a rinsing stroke, and a dehydration stroke are performed for a predetermined time according to a control signal of a controller (not shown) in a state in which laundry and a predetermined amount of detergent are put into the drum 30. Automatic washing proceeds for the laundry.

On the other hand, in the conventional washing apparatus, regardless of the type, contaminants, detergents, softener residues, and mixtures thereof lost from clothes during washing remain on the inner and outer walls of the drum 30 and the inner wall of the tub 20. Due to contamination of the drum and tub), there is a problem that re-contamination of the laundry occurs during washing, thereby reducing the reliability of the device in hygiene.

In addition, odor is generated by bacteria such as molds parasitic in contaminants during crude contamination, and this also causes a problem in that the reliability of the device on the sanitary surface is degraded.

Accordingly, a bath cleaning course has been recently developed, and various contaminants remaining on the inner and outer walls of the drum 30 and the inner wall of the tub 20 are removed by the bath cleaning course to prevent recontamination.

Hereinafter, briefly described for the crude washing course as follows.

First, when it is time to perform a bath wash, and select a bath wash course, the washing water (tap water) together with the bath cleaning detergent into the tub 20 and the drum 30 by the controller is roughly at the time of the washing stroke. It is supplied at the same level as the water level.

At this time, the drum 30 is continuously rotated, the washing stroke proceeds.

As a result, various contaminants remaining on the inner wall surface of the tub 20 and the inner and outer wall surfaces of the drum 30 are separated, and the drainage of the washing water supplied into the tub 20 and the drum 30 continues. The separated contaminants are drained by performing.

When the draining process is completed, new washing water not including detergent is provided to the tub 20 and the drum 30, and the drum 30 is rotated to perform a rinsing stroke.

Thereafter, when the rinsing stroke is completed, the crude washing course is terminated by performing a dehydration stroke after the final drainage.

However, the conventional bath cleaning course as described above causes a problem that waste of water and power is caused because the amount of the washing water used in the rinsing stroke as well as the initial washing stroke is excessively large.

That is, the initial process of the bath washing course is required to keep the drum immersed in the wash water for a long time because the separation of the contaminants attached to the tub 20 and the drum 30 to some extent may be required will be.

In addition, since the temperature of the washing water is not high, the time to keep the drum 30 immersed in the washing water must be long, so that the contaminants can be separated more smoothly, and thus the time required for the course can be considerably longer. There was also a problem that was there.

Of course, if the conditions for washing the tub 20 and the drum 30 are optimized by sufficiently raising the internal temperature of the drum 30, the supply amount of the washing water may be reduced, in which case the temperature rise inside the drum 30 is increased. For this reason, the heating of the heater (not shown) has to be carried out for a long time, and thus, it is not effective due to excessive power consumption.

The present invention has been made in order to solve various problems of the prior art, and an object of the present invention is to provide a washing operation method of the washing apparatus to smoothly wash the tub and drum, even with a small amount of washing water and low power consumption. do.

It is configured to include a steam supply pipe 220 through which the flow of steam vaporized by the heating unit 210 is made.

In addition, the steam supply unit is configured to further include a spray nozzle 230 for discharging the steam flowing through the steam supply pipe 220 into the tub and / or the drum 130. Here, the injection nozzle 230 is configured in the shape of a nozzle (nozzle) to enable a smooth divergence of steam, the end of the injection nozzle 230 is discharged is installed so as to face the inside of the tub 120 This is preferred.

Of course, as shown in Figure 4 may be configured to be in direct communication with the interior of the drum 130 through the rim through the end of the injection nozzle 230, the discharge of the steam is made. In particular, the steam supply unit should be configured to enable the divergence of the selective steam, and for this purpose further comprises an on-off valve 221 for opening and closing of the pipeline on the pipeline of the steam supply pipe 220 embodiment Shall be.

In addition, the temperature sensor 190 is provided at any one portion of the tub 120 to sense a temperature inside the tub 120. In this case, the temperature sensed by the temperature sensor 190 is used to control the operation of the steam supply unit.

In particular, the temperature sensor 190 is preferably configured not to be directly affected by the steam provided into the tub 120 by the steam supply for sensing the correct temperature.

Here, the connecting portion of the circulation passage 310 and the tub 120 is preferably provided with a spray means 320 for spraying the circulated washing water. The injection means 320 is disposed to communicate with the inner space of the tub 120 through the gasket (112 of FIG. 4) provided between the tub 120 and the washing machine body 110, the injection means ( The washing water sprayed from 320 may be configured to be sprayed into the drum 130.

Meanwhile, reference numeral 150 denotes a detergent container in which detergent is stored, and 160 denotes a heater for heating washing water (or washing water).

Hereinafter, the washing operation method according to the first embodiment of the present invention using the above-described drum type washing machine will be described with reference to the flowchart of FIG. 6 and the state diagrams of FIGS. 7 and 8.

First, when the user selects the washing mode, a controller (not shown) for controlling the operation of the washing machine is supplied with washing water to the steam supply unit, and the tub 120 is operated by operating the heat generating unit 210 of the steam supply unit. And / or, steam is supplied to the drum 130 (S110).

At this time, the steam is generated by the heat of the heat generating unit 210, the generated steam passes through the steam supply pipe 220 and the injection nozzle 230 in order to sterilize or call the interior space of the tub 120 In order to supply the inside of the tub 120 or the drum 130.

The supplied steam is supplied such that the temperature inside the tub 120 and / or the drum 130 can be maintained within a set temperature range. The steam generator 210 is controlled to stop the operation when the temperature inside the tub 120 reaches a set temperature. Here, the set temperature is preferably about 65 ℃.

On the other hand, the drum 130 is preferably rotated during the process of supplying steam in the tub 120, the rotation of the drum 130 is the temperature inside the tub 120 reaches the set temperature is Even after the operation of the heat generating unit 210 is stopped, it is preferably maintained for a predetermined time (about 5 minutes). Through this, the supplied steam may be in uniform contact with the drum 130.

In addition, the operation of the steam supply unit, that is, may be controlled to repeatedly perform the operation (heating) and the operation of the heat generating unit 210. Here, it is preferable that the range of the said set temperature range is a range between about 60 degreeC-100 degreeC. The temperature range is a temperature range in which contaminants adhered to the inner wall surface of the tub 120 or the inner and outer wall surfaces of the drum 130 may be separated most smoothly. Confirmation of the temperature is made by the temperature sensor 190.

In particular, since the temperature range is a range in which microorganisms and the like existing on the inner wall surface of the tub 120 or the inner and outer wall surfaces of the drum 130 can be sterilized, a sterilizing effect is also obtained.

In addition, while the steam supply is in progress, a predetermined amount of washing water supply (S120) is performed into the tub 120 under the control of the controller. Here, the washing water supply (S120) may be made at the same time as the process of supplying the washing water to the steam supply unit, the steam 120 is supplied to the inside of the tub 120 or drum 130 after the sterilization process is performed the tub 120 More preferably, water is supplied to the washing water.

At this time, the washing water to be supplied will contain a detergent for washing the bath (drum (tub) and tub) accommodated in the detergent container 150 while passing through the detergent container 150.

In addition, the water level of the water to be supplied is most preferably set to a level such that the surface of the lowermost side of the drum 130 can be wetted, as shown in FIG. This is to minimize the amount of washing water and at the same time to achieve a state containing a high concentration of detergent to achieve the maximum washing effect.

In particular, even if the amount of the washing water is minimized, the washing effect may be improved. Since the inside of the tub 120 forms a high temperature and high humidity environment due to steam, contaminants present on the inner and outer walls of the drum 130 within a short period of time. This is because it is separated smoothly. Therefore, waste water and waste of time generated by operating the entire drum 130 in the wash water for a long time to separate the contaminants are solved.

On the other hand, it is preferable that the drum 130 is continuously rotated while at least one of the above-described steam supply process or water supply process in the tub is in progress. At this time, the drum 130 is preferably controlled at a slower speed than the rotational speed during the washing stroke, it is preferably controlled to rotate only in one direction. Of course, the rotational speed of the drum 130 may not only be the same as the rotational speed during the washing stroke, but may also be controlled to be reversed left and right repeatedly.

In detail, it is preferable that the drum 130 is tumbled while the water supply is in progress. The tumble is a rotation speed in which laundry is in close contact with the inner wall of the drum 130 by centrifugal force (rotation to overcome gravity acceleration). As the speed, the drum 130 is rotated at a low speed of less than 1G or more), or the drum 130 is rotated at a low speed by stirring in the forward and reverse directions.

However, considering that the stroke is for washing, the drum 130 may be rotated in one direction at a slow speed in order to provide a time for the detergent contained in the washing water to sufficiently react with the contaminants attached to the surface of the drum 130. It is most desirable to control only rotation.

Then, when the water supply of the washing water is completed, a substantial washing process is performed (S130).

At this time, the washing step is performed by controlling the drum 130 to be inverted left and right at a normal rotational speed, that is, at the same rotational speed as during a normal washing stroke, for a predetermined time.

In addition, when the water supply is completed in the tub 120, the circulation pump 300 is operated for a predetermined time to pump the washing water in the tub 120 to be sprayed toward the drum 130 again into the tub 120. Preferably, the resupply operation is performed. Here, the set time is preferably about 2 minutes after water supply to the tub 120.

The washing water supplied to the tub 120 is pumped by the circulation pump 300 provided at the lower side of the tub 120, circulated along the circulation passage 310, and then again through the upper side of the tub 120. It is injected into the drum 130.

At this time, the connecting portion of the circulation passage 310 and the tub 120 is provided with a spray means 320 made of a spray nozzle, etc., the circulated washing water is preferably sprayed toward the drum (130). Through this, the sprayed washing water more efficiently washes the drum 130 and at the same time the washing water has more momentum, so that the contaminants on the drum 130 can be washed better. This can be increased.

As a result, sterilization and washing of the inner and outer walls of the drum 130 are performed by the above-described series of processes.

In addition, after the series of washing cycles is performed for a predetermined time, the washing water in the tub 120 is drained (S140).

At this time, the washing water to be drained is a state containing the contaminants separated from the inner and outer wall surface of the drum (130). Of course, the drainage of the washing water may not be performed, and may be controlled to proceed with the stroke immediately afterwards. Of course, it is more preferable that the contaminants remaining on the inner and outer wall surfaces of the drum 130 may be smoothly discharged by first performing the draining stroke before the rinsing stroke is performed.

Here, when the drainage of the washing water is completed, the rinsing stroke is performed in a state in which the washing water for the rinsing stroke is resupplied (S160). In the rinsing stroke, the circulation pump 300 is operated for a predetermined time after the washing water is re-supplied to pump the washing water in the tub 120 and to resupply the tub 120 again.

In the rinsing stroke, it is preferable to use fresh washing water that does not contain detergent for washing the bath. In particular, in the process of supplying the washing water for the rinsing stroke, it is preferable to rotate the drum 130 at a low speed so that contaminants remaining on the inner and outer walls of the drum 130 may be smoothly washed.

In addition, the level of the washing water supplied during the rinsing stroke is higher than the level of the washing water supplied during the washing stroke, that is, the water is supplied more than the amount of the washing water supplied during the washing stroke. This is to allow the detergent remaining on the inner and outer walls of the drum 130 to be diluted as much as possible, and also to remove the contaminants adhered to the inner wall of the tub 120 smoothly.

At this time, since the contaminants attached to the inner wall surface of the tub 120 is separated from the inner wall surface of the tub 120 by high temperature steam during the washing stroke, the tub 120 may be rotated by the high speed rotation of the drum during the final dehydration stroke, which will be described later. By increasing the amount of the washing water to the inner wall surface of the) as much as possible to remove the contaminants attached to the inner wall surface of the tub 120 more smoothly.

Here, the water level of the water supplied during the rinsing stroke is at least 1/5 or more 1/3 of the overall height of the drum 130, preferably 1/4, as shown in FIG. It is desirable to keep the water level so that it can be submerged, which is the maximum water level in which the above-described water level is capable of smoothly removing the remaining detergent and removing the remaining contaminants without consuming excessive amounts of washing water. Because.

When the series of rinsing steps as described above is completed, the final washing operation is completed by performing final drainage (S180) and final dehydration (S190).

On the other hand, in the above-described series of operations, the operation of the steam supply unit is preferably controlled (S150) so as to be stopped in the water supply (or before the drainage stroke is performed after the washing stroke is completed) of the new wash water for the rinsing stroke.

This is to minimize the power consumption during the rinsing stroke, since the inside of the drum 130 in a high temperature and high humidity does not significantly affect the washing performance. Of course, the operation of the steam supply unit may be stopped after the entire washing mode is completed.

On the other hand, the driving method for washing according to the first embodiment of the present invention as described above is most effective to clean the inner and outer walls of the drum 130 and the inner wall of the tub 120 using a detergent for washing. It is a control method for washing, and if the detergent is not used, the washing mode may be set to proceed with other forms of control.

9 is a view illustrating a washing operation method of a washing apparatus according to a second exemplary embodiment of the present invention with reference to the washing washing mode when the detergent is not used.

First, when the user selects the washing mode, a controller (not shown) controlling the operation of the washing machine supplies steam to the tub 120 and / or the drum 130 by operating the steam supply unit (S210). )do.

The supply of the steam is preferably continued until the temperature inside the tub 120 reaches a set temperature, and when the temperature inside the tub 120 reaches the set temperature, the steam generator 210 generates heat. Is preferably off. Here, the set temperature is preferably about 65 ℃.

In addition, the supplied steam is supplied such that the temperature inside the tub 120 and / or the drum 130 can be maintained within a set temperature range, which means that the operation control of the steam supply unit, that is, operation and stop It may be controlled to be performed repeatedly.

At this time, the range of the set temperature range is preferably in the range of approximately 60 ℃ to 100 ℃. The temperature range is a temperature range in which contaminants adhered to the inner wall surface of the tub 120 or the inner and outer wall surfaces of the drum 130 may be separated most smoothly.

In addition, the steam supply process is preferably performed for a predetermined time. Here, the predetermined time means that contaminants adhered to the inner wall surface of the tub 120 or the inner and outer wall surfaces of the drum 130 are separated from the inner wall surface of the tub 120 and the inner and outer wall surfaces of the drum 130. It's enough time.

That is, the steam supply process described above is a series of processes that substantially perform a role of soaking and a substantially washing stroke, unlike the process of supplying steam in the first embodiment of the present invention described above.

In particular, the drum 130 during the washing stroke by the above-described steam supply is preferably made to ensure a uniform rotation of the entire area by the continuous rotation is made.

When the above steam supply is performed for a predetermined time, the controller controls the rinsing process to proceed.

That is, rinsing is performed through continuous rotation of the drum 130 for a predetermined time while the washing water for rinsing the predetermined amount into the tub 120 is controlled by the controller (S220).

At this time, the level of the washing water supplied for the progress of the rinsing stroke is approximately at least 1/5 or more 1/3 of the total height of the drum 130 (preferably about 1/4) The water level is enough to be locked.

That is, as in the first embodiment of the present invention described above, the most effective rinsing performance can be obtained by achieving the maximum water level capable of smooth removal of remaining contaminants without consuming excessive amounts of washing water.

When the washing water for the rinsing water is supplied, the circulation pump 300 is driven to move the washing water in the tub 120 along the circulation passage 310. Thereafter, the circulated washing water is resupplied into the tub 120, wherein the circulated washing water is preferably injected into the tub. Through this, the momentum of the washing water inside the tub can be increased.

In addition, as described above, the drum 130 may be tumbled while water is supplied to the washing water for the progress of the rinsing stroke. That is, the drum 130 is controlled to be continuously rotated in one direction, it is preferable to control so that the rotational speed of the drum 130 is rotated at a slower speed than in the general washing stroke.

Of course, the rotation of the drum 130 is controlled to be rotated while repeatedly inverted left and right. In addition, when the water supply of the washing water for the progress of the above-described rinsing stroke is completed, a substantial rinsing stroke is performed, wherein the drum 130 is inverted left and right at a normal rotational speed, that is, the same rotational speed as during a normal washing stroke. Controlled.

When the rinsing stroke is completed by the above-described series of processes, the final washing operation is completed by performing final drainage (S240) and final dehydration (S260).

In the above-described series of processes, the operation of the steam supply unit is preferably controlled to be stopped after the washing stroke is completed and before the draining stroke is performed. Of course, the operation of the steam supply unit may be controlled to be stopped after performing the drain stroke or before the water supply of the washing water for the rinsing stroke.

On the other hand, the washing operation method according to the first embodiment and the washing operation method according to the second embodiment of the present invention as described above is more preferably provided to be used according to the needs of the user.

Accordingly, in the third embodiment of the present invention, a series of controlling so that the washing mode using the detergent and the washing mode without the detergent may be selectively performed according to the needs of the user, that is, whether the detergent is used or not Present the process.

This will be described in more detail with reference to the accompanying flowchart of FIG. 10.

First, when the selection of the washing mode is made by the user, the controller (not shown) checks whether the corresponding mode uses a dedicated detergent for washing in step S310.

In addition, if it is confirmed that the use of the exclusive detergent is selected as the result of using the exclusive detergent, the tub 120 and / or the drum 130 are supplied with steam (S321) and the exclusive detergent is contained. The washing water is supplied into the tub 120 to control to perform the washing step (S322).

At this time, when the execution of the washing cycle is completed, after performing the same rinsing stroke as in the operation method according to the first embodiment of the present invention described above, the final drainage and final dehydration stroke (S323) to perform the washing mode. To complete.

If, as a result of checking whether the exclusive detergent is used, it is determined that the use of the exclusive detergent is not selected, the steam 120 is supplied to the tub 120 and / or the drum 130 (S331) and the drum 130. ) Is continuously rotated to perform a washing operation in which the contaminants are separated from the tub 120 and / or the drum 130 by the steam (S332), and the washing water containing no dedicated detergent is added to the tub 120. ) Into the control to control the rinsing stroke (S333) to proceed.

At this time, when the washing and rinsing stroke is completed, the washing and draining step (S334) as in the operation method according to the second embodiment of the present invention described above is performed to complete the washing washing mode.

Of course, after the water supply for the washing and rinsing stroke is made, the washing water in the tub 120 is pumped by the circulation pump 300 and sprayed into the drum 130 into the tub 120. The resupply process may proceed further for a set time.

In addition, the idea of this invention is not limited only to each Example mentioned above.

That is, the washing operation method of the washing apparatus according to the present invention is applicable to not only a drum type washing machine but also a general pulsator type washing machine.

As described above, the operating method of the washing machine according to an embodiment of the present invention, by using the steam to perform the washing mode to achieve a high temperature and high humidity environment inside the drum, contaminants from the tub and / or drum easily It is separated, thereby minimizing the amount of washing water used, and has the effect of minimizing the progress of the operation.

In addition, since the washing water is circulated by the circulation pump for a predetermined time after the water supply is completed inside the tub, the drum may be washed better by spraying the drum again.

In addition, since the discharge side of the steam supply unit is provided in a state that is in communication with the inner space of the tub can be manipulated so that the user is more conveniently supplied with steam into the tub.
