Description

Washing machine

The present invention relates to a method of operating a washing machine, and more particularly, it is possible to wash the laundry with a small amount of washing water consumption and low power consumption, and to minimize damage to the cloth regardless of the type of laundry (eg, cloth). The present invention relates to a laundry machine having a new structure that allows washing to proceed.

Generally, a washing machine is classified into a pulsator type washing machine in which a drum is set in a vertical direction, and a drum washing machine in which the drum is laid in a 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.

FIG. 1 schematically shows a conventional structure of the above-mentioned drum washing machine.

That is, the drum washing machine includes a main body 10, an out tub 20 mounted in the main body 10, a drum 30 rotatably mounted in the out tub 20, and the drum 30. It is configured to include a driving means for driving.

Here, the front of the main body 10 is formed with an inlet 11 through which laundry is introduced, and a door 40 for opening and closing the inlet 11 is mounted at a peripheral portion of the inlet 11.

In addition, a rim 50 for sealing between the door 40 and the inlet 11 is mounted on the inner circumference of the inlet 11.

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

In addition, the drum 30 is rotatably mounted in the outer tub 20 and is a portion for performing substantial washing in a state in which laundry is inserted.

At this time, a plurality of dehydration holes 31 are formed on the circumferential surface of the drum 30 so that the washing water supplied into the out tub 20 can be smoothly flowed into the drum 30 and the drum during the dehydration stroke. Washing water in 30 can be smoothly discharged to the outer tub 20.

In addition, the driving means includes a drive motor 71 for driving the drum 30, and a belt 72 connected to the belt pulley 73 to transfer the driving force of the drive motor 71 to the drum 30. It is configured by.

In particular, in recent years, a washing machine is provided with a drying device, and is configured to be able to dry laundry after washing.

At this time, the drying apparatus is provided on the hot air supply pipe 81 and the pipe of the hot air supply pipe 81 provided along the upper space of the tub 20 in the main body 10, as shown in FIG. It comprises a drying heater 82 for heating the air flowing through the hot air supply pipe 81, and a blowing fan 83 provided on the air discharge side of the hot air supply pipe 81 to perform forced circulation of the air.

The washing process of the combined drying drum washing machine having the above-described structure is generally performed while sequentially performing a washing stroke, a rinsing stroke, a final dewatering stroke, and a drying stroke.

At this time, in the washing stroke, the contaminants are separated by friction between the laundry and the drum 30 due to the separation of the contaminants by the detergent and the continuous rotation of the drum 30.

In addition, in the rinsing stroke, the process of rinsing the remaining detergent and contaminants generated during the washing stroke through the supply of new wash water and the repeated rotation of the drum 30 is rinsed.

In the final dehydration stroke, the drum 30 is rotated at a high speed (approximately 800 RPM to 1300 RPM) to remove water from the rinsed laundry.

In addition, in the drying process, a process of drying laundry with the high temperature air by continuously supplying high temperature air into the drum 30 by driving the blower fan 83 together with the heating of the drying heater 82 is performed. .

However, the conventional washing machine as described above has various problems as described below.

First, the washing machine according to the conventional structure has a problem that a large amount of washing water is consumed for washing the laundry and the overall washing time is also long.

Second, since the washing machine according to the conventional structure requires a separate drying device for a drying stroke, addition of manufacturing cost is caused, and the structure of the washing machine main body 10 is complicated by the application of the drying device. Have

In particular, it takes a considerable time to allow the user to achieve the desired amount of laundry drying through the drying stroke, during which the heating of the drying heater 82 and the driving of the blower fan 83 must be performed at the same time. Because of this, power consumption has to be considerably large.

Third, the washing machine according to the conventional structure has a problem in that the stroke changes in accordance with the degree of contamination of the laundry, but the time of each stroke increases or decreases according to the amount of laundry.

In particular, laundry that cannot be washed using laundry water and detergents, such as laundry that requires dry cleaning, has a problem that its washing is difficult.

The present invention has been made to solve the above-mentioned various problems with the prior art, an object of the present invention is to provide a laundry machine of a new structure capable of completing the washing within a short time and low power consumption.

In particular, it is an object of the present invention to provide a laundry machine of a new structure that allows washing to proceed while minimizing damage to the cloth, regardless of the type of laundry (eg, cloth).

According to an aspect of the present invention for achieving the above object while the laundry is put, a drum formed with a plurality of dehydration holes having a diameter of 1 mm or less on its circumferential surface; And, there is provided a washing apparatus comprising a drive motor: driven to rotate the drum at high speed at a rotational speed of at least 2000 RPM or more.

Hereinafter, with reference to Figures 3 and 4 showing preferred embodiments according to the laundry apparatus of the present invention described above in detail.

First, the laundry machine according to the first embodiment of the present invention has a main body 110 forming an appearance as shown in FIG. 3 attached as a drum type washing machine, and a plurality of dewatering holes 131 having a diameter D1 of 1 mm or less. It comprises a drum 130 formed along its circumferential surface, and a drive motor 171 driven to rotate the drum 130 at a high speed of at least 2000 RPM or more.

Here, the drum 130 is rotatably provided in the main body 110, it is configured so that the opened portion in which the laundry is put into the front.

In addition, it is preferable that the outer tub 120 is provided between the main body 110 and the drum 130 like a conventional drum washing machine, and the outer tub 120 supports the rotation of the drum 130. It plays a role.

In particular, the reason why the plurality of dehydration holes 131 formed on the circumferential surface of the drum 130 to have a diameter of 1 mm or less is to minimize damage to laundry.

If the dehydration hole 131 is formed to have a diameter of about 2 to 3 mm, such as the dehydration hole 31 of the conventional general drum 30, the high speed rotation of the drum 130 (eg, rotation of 2000 RPM or more) is performed. If made, the laundry is caught in the dehydration hole 31 causes damage to the cloth.

Therefore, the dehydration hole 131 is preferably formed to form a diameter of 1mm or less to prevent the pinching of the cloth.

At this time, the dehydration holes 131 forming the diameter of 1mm or less is more preferably formed than the number of the respective dehydration holes 31 of the conventional general drum (30).

This is to allow the moisture separated from the laundry in the drum 130 to be smoothly discharged.

In addition, each of the dehydration holes 131 is not limited to being all formed only with a diameter of 1 mm or less, and some of the dehydration holes 132 have a diameter D2 of 1 mm or more, that is, a conventional dehydration hole ( 31) may be formed to form a 2-3mm.

At this time, the dewatering hole 132 constituting the diameter of 1mm or more is to allow the water separated from the laundry to be discharged smoothly to the outer tub 120, in order to minimize the damage of the cloth to the diameter of 1mm or more The number of dehydration holes 132 to be formed should be smaller than the number of dehydration holes 131 to form a diameter of 1 mm or less.

In addition, the drum 130 may be configured to be inclined downward from the front side to the rear side as shown in the embodiment, but may also be configured to achieve a state lying horizontally with respect to the main body 110.

As described above, if the drum 130 is installed to be inclined downward toward the rear, laundry is biased to the rear side of the drum 130 when the washing stroke is performed.

Therefore, the dehydration holes 131 having a diameter of 1 mm or less are preferably formed on the rear side circumferential surface of the drum 130, and the dehydration holes 132 having a diameter of 1 mm or more are formed to smoothly discharge the water. It is preferably formed on the front circumferential surface of the drum 130 which is extremely insensitive to laundry.

In addition, the driving motor 171 according to the first embodiment of the present invention uses a belt 72 and a separate belt pulley 73 as a conventional motor as a motor driven to rotate the drum 130. In this case, the driving force of the driving motor 171 may be transmitted to the drum 130, but it is preferably provided to be directly coupled to the drum 130.

This is because the drive motor 171 according to the embodiment of the present invention should be able to rotate at a rotational speed of at least 2000 RPM or more is a structure in which the driving force loss can be reduced as much as possible.

In particular, the first embodiment of the present invention is characterized in that the drive motor 171 is a motor configured to rotate up to 4000RPM.

The reason why the high-speed rotation of the drive motor 171 is configured as described above is to wash by separating the water containing contaminants from the laundry in the drum 130 by centrifugal force by the high speed rotation of the drum 130. To do this.

That is, instead of washing with a large amount of washing water as in the conventional general washing stroke, the contaminants on the laundry are centrifuged from the laundry by using the high speed rotation of the drum 130 in a state in which a small amount of water is called. .

On the other hand, since the structure according to the first embodiment of the present invention is operated to centrifuge the contaminants from the laundry by the high speed rotation of the drum 130 during the washing process does not require a large amount of wash water.

In particular, it is preferable that the contaminant should be called in such a state that a smooth separation from the laundry is possible before the high speed rotation of the drum 130 is performed.

Therefore, the first embodiment of the present invention is characterized by further comprising a steam dissipation device so that the soaking of the contaminants can be made smoothly with a small amount of water.

At this time, the steam dissipation device is to generate a high temperature steam to be sprayed into the drum 130, so that the contaminants can be smoothly made by the high temperature steam.

The steam dissipation device is installed to provide steam into the drum 130 by heating the hot water into the drum 130, and is provided in the water reservoir 200 and the water reservoir 200 to receive the washing water for steam generation. It includes a heat supply unit 210 for providing a high temperature heat to vaporize the water and the steam supply pipe 220 is made of the flow of steam vaporized by the heat generating unit 210.

In addition, the steam diverging device further comprises a spray nozzle 230 for discharging steam flowing through the steam supply pipe 220 into the drum 130.

At this time, the injection nozzle 230 is configured in the shape of a nozzle (nozzle) to enable a smooth divergence of steam, the end of the discharge of steam is preferably installed to face the drum 130.

The structure of the laundry apparatus according to the first embodiment of the present invention configured as described above may wash laundry by sequentially performing the same series of processes, that is, a washing stroke, a rinsing stroke, and a dehydration stroke. Washing is possible even with the use of wash water and minimal power consumption. An example of this is described below.

First, the method of performing the washing with the minimum amount of washing water and the minimum power consumption using the structure according to the first embodiment of the present invention proceeds greatly including a steam supplying step and a contaminant separating step.

In this case, the steam supplying step is a process for soaking of contaminants from the laundry introduced into the drum.

That is, by supplying steam into the drum 130 for a predetermined time through the control of the steam dissipation device to supply moisture to the laundry in the drum 130 to be called contaminants.

In particular, since the steam is in a high temperature state, soaking of contaminants on the laundry can be made more efficiently.

At this time, the high temperature steam is generated while the water supplied to the steam dissipating device is evaporated by the heat generated by the heat dissipating unit 210 forming the steam dissipating device, and the generated steam is guided by the steam supply pipe 220. After the flow, it is provided into the drum 130 through the spray nozzle 230.

The steam supply process into the drum 130 is preferably controlled to be continuously performed for a time enough to be called for the laundry in the drum (130).

This is desirable if the steam is not enough to affect the laundry if performed only for a short time, so that the soak may not be made so that it lasts for a time until a sufficient soak is made.

Of course, providing steam for too long is not desirable because the amount of water consumed and power consumption can be large compared to the soaking effect.

In this case, the soaking of the laundry is a process of reaching a state in which contaminants can be separated from the laundry smoothly.

The washing of the laundry may be performed by the steam because the contaminants may be smoothly separated from the laundry affected by the steam, considering that the steam is formed at a high temperature and a large amount of water.

Of course, if the laundry is seriously contaminated, the above-mentioned steam due to steam may not be completely made, but if it is lightly contaminated, the steam due to the steam may be smoothly made.

In addition, while the above-described steam supply is in progress, by washing the drum 130 at a low rotational speed (for example, the rotational speed in the existing general washing stroke), the laundry is affected by the steam supplied into the drum 130 It is desirable to be provided evenly.

In addition, as described above, the steam supplied into the drum 130 may be more than a temperature at which sterilization of the laundry is possible.

That is, by performing the washing and at the same time to sterilize the laundry to improve the user's satisfaction with the washing performance.

Then, when the contaminants are separated from the laundry by the steam supply for a predetermined time as described above, the controller controls the steam dissipation device to stop the steam supply and stop the driving of the drum 130. do.

In addition, the controller rotates the drum 130 at a high speed of at least 2000 RPM through the operation control of the driving motor 171.

The drive motor 171 is preferably configured to rotate the drum 130 at a rotation speed in the range of about 3000 ~ 4000RPM.

This is to allow various contaminants attached to the laundry by the high speed rotation of the drum 130 to be smoothly separated from the laundry by receiving the centrifugal force.

At this time, the drum 130 can be rotated in the range of about 3000 ~ 4000RPM is possible because there is very little moisture in the drum (130).

That is, in the conventional washing process using a large amount of wash water, when the drum 130 is rotated at a high speed to the above-described range, considerable vibration is generated due to the influence of the wash water, which inevitably degrades reliability.

However, if washing is performed using only a small amount of steam without using a large amount of washing water as in the present invention, the drum 130 may be rotated at a high speed, and contaminants may be formed by a considerable high-speed rotation of the drum 130. It is separated from the laundry under centrifugal force.

Therefore, as described above, when the drum 130 is rotated in the range of about 3000 to 4000 RPM, the contaminants and water in the state of being called from the laundry by the steam supplying step are applied with centrifugal force due to the high speed rotation of the drum 130. Centrifuge from the laundry while receiving.

At this time, the contaminants and water separated from the laundry are discharged to the outer tub 120 while passing through the respective dehydration holes (131, 132) formed in the drum (130).

Of course, when the drum 130 is rotated at a high speed in the range of about 3000 to 4000 RPM, the laundry may try to pass through the dehydration hole 131 by the centrifugal force.

However, since the dehydration holes 131 formed at the position to be affected by the laundry are formed to have a diameter of 1 mm or less, the problem that the laundry is caught in each of the dehydration holes 131 is prevented in advance. Damage to the fabric is prevented.

In particular, since the drum 130 is mounted inclined downward toward the rear side, most of the laundry is located at the rear side of the drum 130.

Therefore, only the water and contaminants centrifuged from the laundry by each dewatering hole 132 having a diameter of 1 mm or more formed on the front circumferential surface of the drum 130 to further improve the effect of draining water and contaminants. This is smoothly discharged, the problem that the laundry is caught in the dehydration hole 132 is prevented.

As described above, when the separation of the contaminants from the laundry is completed by the high speed rotation of the drum 130, the controller stops the driving of the driving motor 171 to stop the rotation of the drum 130 to terminate the washing.

At this time, the contaminant separation step through the high-speed rotation of the drum 130 may be dried in consideration of the separation of the contaminants from the laundry as well as the moisture is also separated.

As a result, washing and drying can be performed even with minimal washing water and minimum power consumption in the structure according to the first embodiment of the present invention.

On the other hand, the drum 130 of the characteristic structure of the washing apparatus proposed in the first embodiment of the present invention, that is, a plurality of dewatering holes 131 having a diameter of 1 mm or less along its circumferential surface and the drum ( The configuration including the drive motor 171 driven to rotate 130 at a high speed of at least 2000 RPM at a rotational speed is not applicable only to the drum washing machine.

That is, as shown in the second embodiment of the present invention shown in FIG.

At this time, not only the dehydration hole 331 having a diameter of 1 mm or less is formed on the circumferential surface of the drum 330 but at least 1 mm in diameter so as to further improve the effect of discharging moisture and contaminants. It is preferable to further form one or more dehydration holes (332).

In particular, the dehydration hole 332 formed to have a diameter of 1mm or more is preferably positioned on the upper circumferential surface of the drum 330 to minimize the problem of pinching the laundry.

This, when considering that the drum 330 is erected in a vertical direction, the laundry is located only at the bottom of the drum 330 by its own gravity, the upper portion of the drum 330 is not affected by the laundry Because.

In addition, the driving motor 371 which is driven to rotate the drum 330 at a high speed at a rotation speed of 2000 RPM or more passes through the outer tub 320 at the bottom of the outer tub 320 and the drum (or pulsator). 330 is axially coupled.

Of course, the pulsate type washing machine according to the second embodiment of the present invention is further provided with a steam dissipation device including a water reservoir 200, a heat generating unit 210 and a steam supply pipe 220 as shown. desirable.

As described above, the washing apparatus according to each embodiment of the present invention is configured to enable a high speed rotation of the drum at least 2000 RPM or more (preferably 3000 to 4000 RPM) so that the washing of the laundry to the high speed rotation of the drum It is possible to proceed by the centrifugal force according to have the effect of enabling the laundry to proceed with the minimum washing water consumption and minimum power consumption.

In addition, the cloth damage caused by the laundry being caught in the dehydration hole by the centrifugal force due to the high speed rotation of the drum has an effect that can be solved by forming the diameter of the dewatering hole to 1mm or less.

In particular, when the drum is rotated at a high speed, the dehydration hole having a diameter of 1 mm or more is formed at a portion that is not provided with the influence of the laundry as much as possible, so that the pollutants and water separated from the laundry by centrifugal force can be smoothly discharged.

In addition, since the moisture contained in the laundry can be centrifuged by the high speed rotation of the drum, the laundry can be dried without having a structure for a separate drying device.
