Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a washing machine that performs washing and dehydration of laundry in a rotating drum that is rotatably disposed in a water receiving tub elastically supported in a washing machine body.
[0002]
[Prior art]
  Conventionally, this type of washing machine is configured as shown in FIG. Hereinafter, the configuration will be described.
[0003]
  As shown in the figure, the rotating drum 1 is provided with a large number of water passage holes 2 on the entire outer periphery thereof, and is rotatably disposed in the water receiving tank 3. One end of the horizontal shaft 4 is fixed to the rotation center of the rotary drum 1, and a drum pulley 5 is fixed to the other end of the horizontal shaft 4. The motor 6 is connected to the drum pulley 5 by a belt 7 and rotationally drives the rotary drum 1. A lid 8 is provided at the opening of the rotary drum 1 so as to be freely opened and closed.
[0004]
  The water receiving tub 3 is suspended from the washing machine main body 9 by a spring body 10, and is supported by anti-vibration so that vibration during dehydration is not transmitted to the washing machine main body 9 by the anti-vibration damper 11, and also reduces vibration during dehydration. A weight 12 is provided. The heater 13 heats the washing water in the water receiving tub 3. The control device 14 controls operations of the motor 6, the heater 13, and the like, and sequentially controls a series of processes such as washing, rinsing, and dehydration.
[0005]
  The operation in the above configuration will be described. When the lid 8 is opened, the laundry in the drum 1 is put in, and the operation is started, the drum 1 is rotated at a low speed by the motor 6 in the washing process, and the laundry in the drum 1 is driven. Is lifted and dropped onto the water surface. Thus, the washing process proceeds. In the rinsing process, the same operation as in the washing process is performed.
[0006]
  In this case, the water in the water receiving tub is supplied at a level that does not overflow from the inlet, and is rinsed by being stored in the water receiving tub.
[0007]
  Explaining the movement of the rotating drum 1 in this configuration, the rotating drum 1 rotates at low speed when the motor 6 is turned on. A typical motor control here is shown in FIG. This low-speed driving rotation may be continued or sometimes stopped. There is a case where the rotation direction is only one direction, and there is a case where the rotation is reversed left and right. By this low-speed drive rotation, the clothes in the rotary drum 1 are lifted upward from a baffle provided on the inner periphery of the rotary drum 1 and projecting inward of the rotary drum, and then fall downward. The reason why the rotation is slow is to suppress the action of the centrifugal force and to surely perform this dropping operation. Here, the impact of the drop and the rubbing between the clothes occur, and the bond between the dirt on the clothes and the clothes fibers weakens and is removed by the washing water. Further, the washing water contained in the clothes is pushed out by the impact at this time, and the dirt on the clothes can be efficiently removed.
[0008]
  Such an impact due to the fall of clothes and the operation of taking in and out washing water are indispensable components in a rotary drum type washing machine.
[0009]
[Problems to be solved by the invention]
  However, in such a conventional configuration, those with a dry mark display such as yarn and fashionable clothes are always subject to impact and friction due to falling, so mechanical force is applied, and shrinkage, damage, texture, etc. are impaired. Problems arise. In particular, wool yarn and the like have a drop impact, so that a felt phenomenon occurs in which the knitted yarn's eyes are clogged, causing severe shrinkage. In addition, damage due to surface rubbing is severe, and dirt is removed, but the garment body becomes unusable.
[0010]
  SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and it is an object of the present invention to realize a finish that does not impair damage, shrinkage, and texture of clothes by washing clothes on a dry cleaning display with a rotating drum.
[0011]
[Means for Solving the Problems]
  In the washing machine of the present invention, the rotary drum is driven at an angle within a range in which the clothes do not roll, and the clothes in the rotary drum are hardly moved by the swing of the rotary drum, and gradually become delicate clothes. By absorbing and soaking the washing water, the dirt can be removed with almost no mechanical force.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
  The invention according to claim 1 of the present invention comprises a rotating drum having a rotation center axis in a substantially horizontal direction and throwing in clothes, a water receiving tank containing the rotating drum,SaidRotating drumRotateA motor,SaidWater supply means for supplying water into the rotating drum;SaidControl means for controlling the drive of a motor and water supply means, etc., the control means,In the water supply process until the predetermined washing water level is reached,As long as the clothes in the rotating drum do not rollSaidRotating drumSwingsRotateBetween the repeated swinging motions of the rotating drum, the rotating drum is rotated beyond the range where the clothes in the rotating drum do not roll, and the water level is changed. ON / OFF control of the water supply means so as to rise in stagesConstitutionIt is what.
[0013]
According to this configuration, when water is supplied to the first predetermined water level until the predetermined washing water level is reached, clothes such as the sweater are floated on the surface of the water, and water is gradually absorbed by the subsequent rotation and swinging of the rotating drum. It is sinking. If the rotating drum continues to rotate and swing in this state, the contact between the baffle and the clothing due to the rotation of the rotating drum becomes excessive, and a large mechanical force acts on the clothing. Therefore, by supplying water up to the second predetermined water level and swinging the rotating drum, it is possible to promote further water absorption into the clothing in a state where the clothing is lifted again and there is no excessive contact between the baffle and the clothing. The mechanical force applied to the clothing is extremely small, and washing is possible without damaging the wound, shrinkage, or texture.
[0014]
Claims of the invention2The described invention is claimed.1'sIn addition to the invention, the control meansIn the initial stage of the water supply process, water supply is started with the rotating drum rotating at a rotation speed at which clothing does not fall. After the elapse of a predetermined time or after reaching a predetermined water level, the operation is changed from the operation in which the rotating drum rotates at a rotation speed at which clothing does not fall to the swinging operation in which the rotating drum swings and rotates.It is a configuration.
[0015]
  With this configuration, the mechanical force applied to the garment is extremely small without causing a felting phenomenon, and washing can be performed in a short time without impairing the damage, shrinkage, and texture of the garment.
[0016]
  Claims of the invention3The invention described in claim 1Or 2In addition to the described invention, the control meansIn the swinging operation of the rotating drum, the motor is driven only in one direction at the start thereof.As a result, the garment gradually moves in one direction, and its vertical and horizontal positions or the relative positions of several garments can be interchanged, and the mechanical force applied to the garment in a short period of time is extremely small. The synergistic effect makes it possible to wash clothes in a short time without impairing the damage, shrinkage or texture of clothing..
[0017]
【Example】
  A first embodiment of the present invention will be described below with reference to the drawings. In addition, the thing of the same structure as a prior art example attaches | subjects the same code | symbol, and abbreviate | omits description.
[0018]
  The mechanical configuration of the present embodiment and the conventional example is the same as that of the conventional one. However, this control has the following characteristics regarding the control in the cleaning process and the rinsing process.
[0019]
  In FIG. 17, when clothes are put into the rotating drum 1 and then a start button (not shown) is pressed, the rotating drum 1 starts rotating. The rotating drum is continuously driven to increase the rotational speed sequentially. At this time, when the clothes in the rotating drum 1 reach a certain number of rotations or more, the clothes are lifted and dropped by the baffles in the rotating drum, but the centrifugal force of the rotating drum overcomes gravity, as shown in FIG. In this state, the inner wall surface of the rotating drum 1 is evenly attached.
[0020]
  In such a state, water supply (not shown) is started from the water supply port, and when the water level reaches a predetermined water level or after a predetermined time has elapsed, the water supply is temporarily stopped. The relationship between the water supply at this time and the driving of the rotating drum is shown in FIGS. Even if the continuous drive of the rotating drum is limited by time as shown in FIG.Also figureEven if it is restricted by the water level as shown in 3, the same effect can be obtained.PlayingTo do.
[0021]
  Without going through this process, water supply is started before the rotating drum is driven and clothes are immersed in water, and then the rotating drum starts rotating. When it acts, a felting phenomenon occurs in which the fibers are entangled with each other.
[0022]
  Therefore, as described above, in a dry state immediately after putting the clothes into the rotating drum 1, the rotating drum is driven at a rotational speed (about 80 r / min or more) at which the clothes such as the setter do not fall, and water is supplied to the clothes. StickingKiWater absorption into clothing can be promoted in a short time without any mechanical force acting. Accordingly, the mechanical force applied to the garment is extremely small without causing a felting phenomenon, and washing can be performed in a short time without impairing the damage, shrinkage, and texture of the garment.
[0023]
  Next, driving of the motor 6 that drives the rotary drum 1 and control of the water level until the predetermined washing water level is reached will be described.
[0024]
  First, this rotating drum1The motor 16 to be driven is driven by the control device 14 as shown in FIG. That is, the rotary drum 1 is first driven in one direction to the extent that clothing does not roll, and then the motor 6 is turned off to swing the rotary drum 1. At this time, as shown in FIG. 4, the rotary drum 1 is moved once in the direction a and then moved in the opposite direction by a1, and further swung with a2, a3, and a4. Converges to the stop position. The rotating drum 1 of the present embodiment drives the rotating drum 1 in the direction opposite to the previous driving direction in the middle of the swing that does not reach the stop position, and repeats such driving and swinging of the rotating drum 1. .
[0025]
  Control of the motor 16 at this time is performed while detecting the rotation of the rotating drum 1 with a rotation sensor (not shown) installed behind the rotating drum. This rotation sensor generates a pulse every time the rotary drum 1 rotates 1/10, and the motor 16 is driven by detecting the two pulses and then turning off the motor 16 and stopping for 3 seconds. Repeat the drive and swing operation.
[0026]
  The drive sequences of the motor 6 and the water supply valve at this time are shown in FIGS. As shown here, after the driving / swinging process is repeated for a predetermined time, the rotating drum is driven beyond the driving rotation angle T of the rotating drum 1 in the range where the clothes are not rolled in this process, and the clothes roll. Or by promoting the movement, the clothing rises and the penetration of washing water into the clothing is promoted. At this time, the motor 16 is turned on while the pulse from the rotation sensor described above is detected ten times.
[0027]
  Furthermore, simultaneously with the drive control of the motor, as shown in FIG. 5, the water level is increased in stages in stages until the washing water level is reached. Referring to FIG. 5, when water is supplied to a first predetermined water level, clothes such as a sweater are floated on the water surface, and are gradually absorbed and submerged by subsequent drum rotation and swinging. If the drum continues to rotate and swing in this state, the contact between the baffle and the clothing due to the rotation of the drum becomes excessive, and a large mechanical force acts on the clothing. Therefore, by supplying water up to the second predetermined water level and swinging the rotating drum, it is possible to promote further water absorption into the clothing in a state where the clothing is lifted again and there is no excessive contact between the baffle and the clothing. The mechanical force applied to the clothing is extremely small, and washing is possible without damaging the wound, shrinkage, or texture.
[0028]
  In order to further promote this effect, as shown in FIG. 6, first, water is supplied to the first predetermined water level and the rotating drum is driven to swing, thereby facilitating water absorption into clothing and gradually sinking. Here, when the rotary drum is driven, the clothes can be effectively rolled, and the rotation of the rotary drum can be minimized. If the drum continues to rotate and swing in this state, the contact between the baffle and the clothing due to the rotation of the drum becomes excessive, and a large mechanical force acts on the clothing. Therefore, by supplying water to the second predetermined water level immediately after the rolling drive of the rotating drum, the clothing is brought into a floating state again, and there is no excessive contact between the clothing and the baffle due to the driving and swinging of the rotating drum. can do. By continuing the swinging motion of the rotating drum in this state, further water absorption into the garment can be promoted, the mechanical force applied to the garment is extremely small, and washing is possible without impairing damage, shrinkage, and texture.
[0029]
  Next, drive control of the rotating drum after the water level has reached the washing water level will be described.
[0030]
  In the present embodiment, it is preferable to wash the wool theta or fashionable clothes that are washed without applying a large mechanical force. Therefore, the control shown in FIG. 4 is based on the swing drive of the rotating drum performed during water supply. I do. By this rocking drive, the wool setter and fashionable clothes in the rotating drum hardly float and float on the water surface in a semi-submerged state. The clothing in this state is gently swung by the swinging drive of the rotating drum, gradually absorbed and dipped, and can be washed with very little mechanical force applied to the clothing, damaging, shrinking, and feeling the clothing. Laundry is possible without any problems.
[0031]
  Further, as shown in FIG. 7, when the swing drum is driven in one direction, this swinging gradually moves in one direction. The relative positions can be exchanged. Thereby, the water absorption of clothes, such as a wool-made setter, can be accelerated | stimulated in a short time. In particular, wool garments, etc. will be damaged significantly by keeping them wet for a long time, so the garment is damaged, shrunk, and textured by a synergistic effect of cleaning in a short time and the mechanical force applied to the garment being extremely small. Washing can be performed in a short time without impairing.
[0032]
  In this embodiment, the rotary drum 1 is swung by turning off the motor 6. However, this swinging operation may be realized by driving the motor. For example, when the amount of clothing is small, natural swinging due to the weight of the rotating drum 1 may cause the swinging to immediately converge and the rotating drum 1 to stop, or in some cases, no swinging may occur. Because. The rotation angle T of the rotary drum shown in FIG. 4 when performing the driving / swinging operation is an angle of about 120 degrees at the maximum so that the movement of the clothes is suppressed as much as possible and the clothes do not roll or fall. The rotation angle T may be varied depending on the type and amount of clothing. For example, if the garment is light and slippery and the amount is small, the rotation angle T is small, and if the garment is water-absorbent and the amount of cloth is large, setting the rotation angle T large is effective. Is.
[0033]
  Further, as shown in FIG. 8, during the repetition of the driving and swinging operation of the rotating drum 1, by rotating the rotating drum for rolling the clothes, the clothes floating in the water surface in a semi-submersible state are driven. It is possible to change the upper and lower positions or the relative positions of several pieces of clothing, and it is possible to accelerate the water absorption of clothing such as wool setters in a short time. In particular, wool clothing, etc. will be damaged significantly by keeping it wet for a long period of time. Therefore, washing, shrinking, and texture of clothing will be reduced by minimizing the mechanical force applied to the clothing in a short time. Washing can be performed in a short time without impairing.
[0034]
  In particular, a combination of a rotational drive for rolling the clothes on the rotating drum and a swing drive for the rotating drum for swinging the clothes must be combined with a swing drive in the same direction as the rotational drive immediately after the rotational drive. To do. In other words, after the rotary drive of the rotating drum on which the garment rolls, the garment is biased in the direction of rotation of the rotary drum, and then the garment is further reversed gently with a very small mechanical force by the swing drive of the drum in the same direction.・ It can roll. This makes it possible to promote water absorption into clothing in a short period of time, with a synergistic effect that reduces the mechanical force applied to the clothing in a short period of time and in a short time without impairing the damage, shrinkage, or texture of the clothing. Washing becomes possible.
[0035]
  This is because if a swing drive in the direction opposite to this drive is applied immediately after the rotation drive, there is a risk that the clothes rolled by the rotation drive will return to the original position. The clothing is immersed in a little more water and is in a floating state. Even if the rotary drum rotates, depending on the degree of rolling of the clothing, it can be easily returned to the original position by the next swinging drive. Therefore, in order to escape from this situation, the oscillating drive next to the rotational drive is set at least in the same direction as the rotational drive to ensure the rolling of the garment.
[0036]
  As long as the control satisfies this condition, even when the drive is all driven in the same direction as shown in FIG. 9, the swing drive after the rotation drive is controlled to be in the same direction until the next rotation drive as shown in FIG. However, as shown in FIG. 11, it is possible to control that the direction of the other swing operation is free as long as the rotational drive and the swing drive in the same direction are always combined immediately after the rotational drive.
[0037]
  Further, washing and rinsing are performed according to the flow shown in FIG. In other words, the washing water and the rinsing water are not dehydrated until the dehydration process, and control is performed only by drainage.
[0038]
  This is because, when a mechanical force is applied to a wool-made setter or the like in a wet state, a felting phenomenon occurs in which fibers are entangled with each other, resulting in excessive reduction in texture, damage and shrinkage. The mechanical force applied to clothing in a drum-type washing machine is due to falling after being lifted by a baffle during washing and rinsing, and from dropping when the clothing is stuck to the rotating drum at the start of dehydration or less. . The mechanical force due to the latter is a state in which no water is present in the drum, and since the clothes fall directly onto the rotating drum, it becomes very large, greatly affecting the reduction in texture, damage and shrinkage.
[0039]
  In this embodiment, the mechanical force applied to the garment is extremely reduced by performing high-speed rotation of the rotating drum only during the last dehydration process of washing without performing dehydration that has a bad influence on the garment between a plurality of rinses. Washing is possible without damaging, shrinking, or damaging the texture.
[0040]
  Next, a second embodiment having a circulation system will be described.
[0041]
  As shown in FIG. 13, the difference between the present embodiment and the conventional example is that the water in the water receiving tank is rotated in the rotating drum from the opening 17 that opens to the bottom of the water receiving tank through the circulation pump 16. It has the circulation path 15 which injects into the rotary drum from the discharge port 18 above the drum.
[0042]
  The control in the cleaning process and the rinsing process will be described with this configuration. In FIG. 14, first, when the circulation pump is stopped from the water supply port (not shown), the water level is equal to or higher than the lowest point of the rotating drum (water level A), but when the circulation pump is driven. The water is supplied to a water level that is below the lowest point (water level B). Such a water level is set so that when the circulating pump 16 is driven, the circulating water pours from above the rotating drum 1, and the poured circulating water passes through the clothes and surely falls downward. It is what. Even though the circulation pump 16 is driven, if the water level at that time is high and a part of the clothes is below the water level, the circulating water cannot be reliably passed.
[0043]
  When the washing water level reaches the specified water level (water level A), the motor 6 and the circulation pump 16 are driven to drive the rotary drum 1 and the clothes in the rotary drum from above the rotary drum 1 through the discharge port 18 of the circulation path 15. Pour the circulating water into the shower. The circulating water may fall in a circular arc shape around the discharge port 18 and may fall at a position where at least the front inner wall surface and the rear inner wall surface of the rotating drum 1 are continuous. By dropping the circulating water in this manner, the position of the circulating water that falls on the clothes moves as the rotary drum 1 is driven and rocked, and the circulating water falls evenly on the entire clothes, and washing unevenness can be prevented. The discharge port 18 can be swung at a higher speed than the rotating drum 1 so that the circulating water can be dropped evenly from above the rotating drum 1 and the washing unevenness can be further reduced.
[0044]
  Next, drive control of the motor 6 that drives the rotary drum 1 will be described.
[0045]
  The motor 16 for driving the rotary drum 1 is driven by the control device 14 as shown in FIG. That is, the rotary drum 1 is first driven in one direction to the extent that clothing does not roll, and then the motor 6 is turned off to swing the rotary drum 1. At this time, as shown in FIG. 15, the rotary drum 1 is moved once in the a direction, then moved in the opposite direction by a1, and further swung with a2, a3, and a4. Converges to the stop position. The rotating drum 1 of the present embodiment drives the rotating drum 1 in a direction opposite to the previous driving direction in the middle of the swing that does not reach the stop position, and repeats such driving and swinging of the rotating drum 1. .
[0046]
  Control of the motor 16 at this time is performed while detecting the rotation of the rotating drum 1 with a rotation sensor (not shown) installed behind the rotating drum. This rotation sensor generates a pulse every time the rotary drum 1 rotates 1/10, and the motor 16 is driven by detecting the two pulses and then turning off the motor 16 and stopping for 3 seconds. Repeat the drive and swing operation.
[0047]
  Since the water level is below the lowest point of the rotating drum 1 due to the circulation pump 16 being driven during this swinging, the swinging of the rotating drum 1 should be performed smoothly without being disturbed by water. I can do it. In this embodiment, the rotary drum 1 is swung by turning off the motor 6. However, this swinging operation may be realized by driving the motor. For example, when the amount of clothing is small, natural swinging due to the weight of the rotating drum 1 may cause the swinging to immediately converge and the rotating drum 1 to stop, or in some cases, no swinging may occur. Because.
[0048]
  During the swinging / driving operation, the circulating water pours onto the clothing from the discharge port 17 of the circulation path, and the clothing at the falling point of the circulating water moves by swinging, so that the circulating water can be uniformly distributed over the entire clothing surface. Falls down. The rotation angle T of the rotating drum shown in FIG. 3 when performing this driving / swinging operation is an angle of about 120 degrees at the maximum so that the movement of the clothes is suppressed as much as possible and the clothes do not roll or fall. The rotation angle T may be varied depending on the type and amount of clothing. For example, if the garment is light and slippery and the amount is small, the rotation angle T is small, and if the garment is water-absorbent and the amount of cloth is large, setting the rotation angle T large is effective. Is.
[0049]
  The drive sequence of the motor 6 and the circulation pump 16 at this time is shown in FIG. As shown here, after the driving / swinging process is repeated for a predetermined time, the rotating drum is driven C beyond the driving rotation angle T of the rotating drum 1 in the range where the clothes are not rolled in this process, and the clothes are rotated. By promoting movement or movement, the surface on which the circulating water pours is changed, and the surface of new clothing is exposed. At this time, the motor 16 is turned on while the pulse from the rotation sensor described above is detected ten times.
[0050]
  In the cleaning process by the rotating drum 1, the surface on which the circulating water pours is subjected to mechanical shock due to the impact of the circulating water, and the cleaning efficiency is higher than the inside of the clothing or the bottom of the clothing where the impact of the circulating water is not received at all. . Accordingly, if the surface of the garment is not changed at all, uneven cleaning will occur. Furthermore, if the operation of passing the circulating water through the garment is continued without moving the clothing, the path through which the circulating water passes is fixed inside the garment, and the interior of the garment that is off the path is connected to the circulating water. There will be no contact. Then, while changing the surface which hits the circulating water of clothing at any time, rolling the clothing destroys the passage of the circulating water formed in the clothing and forms a new passage. As a result, the circulating water can pass through the entire body including the inside of the clothes and dirt can be removed. Further, the rolling and falling of the garment pushes out the washing water or the like remaining in the garment and promotes the absorption of new circulating water.
[0051]
  Further, as shown in FIG. 16 (a), immediately after the rotary drum 1 is driven at a rotation angle exceeding the range where the clothes do not roll, the circulation pump 16 is stopped for a predetermined time, The water level is once raised above the lowest point of the rotating drum. As a result, the lower part of the garment in contact with the rotating drum 1 is immersed in washing water or the like, the center of gravity is determined below the rotating drum 1, and the drive / swing operation, particularly the swinging operation, is performed smoothly. The soaked washing water or the like falls from the clothing by swinging, thereby facilitating the removal of dirt below the clothing.
