Description

Drum-type washing machine or washing dryer

  The present invention relates to a drum-type washing machine or a washing and drying machine in which a rotating drum is disposed in an outer tub so that the rotation axis of the rotating drum is inclined downward from the front side to the back side.

  Conventionally, this type of drum-type washing machine includes a drum-type washing machine that performs washing with a rotating drum that stores clothes rotatably provided by a rotation shaft set in a horizontal direction (see, for example, Patent Document 1). In the drum type washing machine described in this publication, as shown in FIG. 8, a rotating drum 61 is arranged in a water tub 63 in a washing machine casing 67 so that the rotation axis direction thereof is horizontal. . The door 64 provided on the front side of the washing machine casing 67 is opened, the laundry is put into the rotary drum 61 from the laundry entrance 68 formed in the water tub 63 so as to face the door 64, and the drum is driven. By rotating the rotating drum 61 by the motor 65, the laundry accommodated in the rotating drum 61 is hooked and lifted by the stirring protrusion 66 provided on the inner peripheral wall of the rotating drum 61, and the lifted laundry becomes an appropriate height. The laundry is beaten and washed by falling.

  By providing the drum-type washing machine having the above-described configuration with a drying function, a drum-type washing / drying machine having a function of drying laundry, wet clothes, and the like after dehydration in addition to washing can be configured. That is, when the air is exhausted from the water tank 63, air containing moisture in the rotary drum 61 is exhausted from the through holes 62 formed on the peripheral surface, so that the air containing moisture passes through the dehumidifying means and is then heated. By forming the air circulation path for blowing air in the water tank 63 again by heating by means, the laundry and clothes accommodated in the rotating drum 61 can be dried.

However, the drum-type washing machine or drum-type washer / dryer has a rotating drum placed sideways, so the laundry must be taken in and out from the front side. It has been unsuitable for the situation. In order to solve the problem of this drum type washing and drying machine, it is possible to easily put in and out the laundry by tilting the rotation axis so that the inlet side of the rotating drum faces upward, and to arrange the laundry in a narrow space. A drum-type washing and drying machine that can be used can be configured (see, for example, Patent Document 2).

  However, in the conventional configuration, when the rotating drum is inclined from the horizontal direction, the laundry stored in the rotating drum is positioned at a low position in the rotating drum, that is, on the bottom side of the rotating drum formed in a bottomed cylindrical shape. If the rotating drum is further biased and further rotated, the laundry that is hooked on the stirring baffle provided on the inner peripheral surface of the rotating drum and lifted in the circumferential direction falls to the bottom surface side of the rotating drum when dropped from above.

  At this time, the laundry present at the bottom of the rotating drum rotates synchronously with the rotating drum due to frictional resistance with the bottom wall surface of the rotating drum. Since the laundry present on the inlet side of the rotating drum falls before reaching the uppermost point of the rotating drum, it rotates faster than the rotating drum. Accordingly, a relative speed difference occurs between the laundry on the inlet side of the rotary drum and the laundry present at the bottom, which causes twisting and entanglement between the same laundry and the laundry. Therefore, in the drum type laundry dryer having a structure in which the rotary drum is inclined, there is a problem that the washing and drying functions are not uniformly applied to all the laundry.

  In particular, in the drying process, it is necessary to apply warm air uniformly to the laundry to promote drying. However, when twisting or entanglement occurs, there is a problem that drying time is long and drying unevenness and wrinkles occur. .

  The present invention solves the above-described conventional problems, and has a structure in which the laundry is sufficiently stirred even in a structure in which the rotating drum is inclined, and improves washing performance, drying efficiency, and energy saving. An object of the present invention is to provide a drum-type washing machine or a washing / drying machine capable of shortening the drying time and achieving a good finish with less wrinkling of clothes.

In order to solve the above-described conventional problems, a drum-type washing machine or a washing and drying machine according to the present invention rotates a rotating drum with a bottomed cylindrical shape in which an input port is inclined upward in the outer tub, and the rotating drum. Drive means and a correction body rotatably provided at the bottom of the rotary drum, wherein the correction body moves the laundry positioned at the bottom of the rotary drum and the laundry on the inlet side of the rotary drum. Are provided so as to respond to the movement of the laundry in contact with the corrector .

  As a result, the laundry present at the bottom of the rotating drum accompanying the rotation of the rotating drum has the same rotational speed of the laundry present at the inlet side and the bottom of the rotating drum and the twist of the laundry, Since the entanglement is suppressed, the washing action acts on the entire laundry. In addition, the drying time can be shortened and a finish with less wrinkles can be realized.

  The drum-type washing machine or the washing / drying machine of the present invention can suppress the twist and entanglement of the laundry, improve the washing performance and the drying efficiency, and can realize a finish with less wrinkles.

A first aspect of the present invention is a bottomed cylindrical rotating drum in which an input port is inclined upward in the outer tub, a driving means for rotating the rotating drum, and a corrector provided rotatably at the bottom of the rotating drum. with the door, the straightening body, movement of the such that movement of the laundry inlet side of the rotary motion drum laundry located at the bottom of the rotary drum are the same, the laundry contacting the straightening member Since the laundry present on the bottom of the rotating drum accompanying the rotation of the rotating drum has the same rotational speed, the laundry present on the inlet side and the bottom of the rotating drum has the same rotational speed. Since the twist and entanglement of the laundry are suppressed, the washing action acts on the entire laundry. In addition, the drying time can be shortened and a good finish with less wrinkles can be realized . Further, when the centrifugal force generated by the rotation of the rotating drum and the laundry present at the bottom that is hooked by the stirring baffle provided on the inner peripheral surface of the rotating drum and lifted in the circumferential direction reach the upper side of the rotating drum. Responds to a natural fall from This movement is the same as that on the inlet side of the rotating drum, and the twist and entanglement of the laundry can be suppressed.

In the second invention, since the correction body is supported by the rotation axis of the rotary drum, the correction body can be rotatably attached to the shaft of the rotation drum via a bearing, thereby reducing the size, weight and cost of the main body. The rotation of the laundry lifted by the rotation of the rotating drum and the rotation of the straightening body are coaxial, so that the laundry can be more smoothly dropped and smooth agitation can be performed. .

At the same time, the rotation of the corrective body can be smoothly rotated by the rolling action, and the twist and entanglement of the laundry can be suppressed.

According to a fourth aspect of the present invention, the correction body is provided with a resistance reducing body that reduces the frictional resistance with the laundry, so that the frictional resistance between the laundry and the correction body is reduced, and the laundry is lifted by the rotation of the rotating drum. Since it is dominated by the centrifugal force of the rotating drum and the action of the stirring baffle, the movement of the rotating drum on the inlet side and the bottom side becomes the same, and the twist of the laundry and the entanglement between the laundry are improved.

According to a fifth aspect of the present invention, the resistance reducing body is constituted by a plurality of rotating bodies partially protruding from the surface of the correction body, thereby suppressing the movement of the laundry around the resistance reduction body, and the entire correction body has low friction.

Yes, the frictional resistance between the laundry and the straightened body can be reduced. In addition, even when the laundry reaches the top of the rotating drum, the resistance reducing bodies are arranged in a substantially vertical direction, so that the resistance to the falling of the laundry is low, and the laundry present at the bottom of the rotating drum. Moves in the same way as the inlet side, and twist and entanglement are minimized.

The above-described flow of drying air is configured as a circulation path 22a.

  In order to effectively introduce the drying air flowing through the circulation path 22 a into the rotary drum 4, a non-contact seal portion is formed by the outer side of the bottom wall surface of the rotary drum 4 and the inner side of the outer tub 1. The non-contact seal portion is provided so as to enclose the blowing port 25 and surround the rotating shaft 12 of the rotating drum 4.

  The circulating wind tunnel 22 is provided with a cooling water supply port 28 for supplying cooling water to dehumidify the drying air and a heat exchanger 29. The drying air that has become wet due to contact with the laundry 5 is cooled by the heat exchanger 29 and dehumidified. The cooling water and the dehumidified water are discharged out of the housing 2. A discharge port 30 is provided at the bottom of the outer tub 1, and a drain valve 31 and a drain port 32 are provided downstream of the discharge port 30.

  The operation and action of the drum type washing and drying machine configured as described above will be described below. First, in the washing process, the laundry 5, the detergent, and the washing water are supplied to the rotating drum 4, the driving means 10 is operated, and the rotating drum 4 is operated forward and backward to perform washing for a predetermined time. When the rotating drum 4 is rotated, the laundry 5 is lifted upward by the centrifugal force generated by the rotation of the rotating drum 4 and the action of the agitating baffle 9. It falls toward 4 below. Since the correction body 13 rotates smoothly in conjunction with the fall, the same movement as the laundry 5 present on the side of the charging port 6 of the rotary drum 4 is given.

  A correction body 13 for correcting the movement of the laundry 5 is provided so that the movement of the laundry 5 located at the bottom of the rotary drum 4 is the same as the movement of the laundry 5 on the inlet 6 side of the rotary drum 4. As a result, the laundry 5 present at the bottom of the rotary drum accompanying the rotation of the rotary drum 4 has the same rotational speed of the laundry 5 present at the inlet 6 side and the bottom of the rotary drum 4 and the same laundry 5. Further, since the twist and entanglement between the laundry items are suppressed, the washing action acts on the entire laundry item 5 and a high detergency with no unevenness is obtained.

  The correction body 13 is supported by the rotational axis of the rotary drum 4 and is rotatably mounted via a bearing 14. The rolling body is in contact with the inner bottom wall surface of the rotation drum 4 in the peripheral area of the correction body 13. 15, even if the straightening body 13 receives a load in the bottom direction of the laundry 5, the rolling body 15 can prevent and regulate the deformation in the thrust direction, and the rolling action can rotate the straightening body 13. Can be rotated smoothly. In addition, the configuration is simple and a reduction in size and weight can be realized.

  Next, a rinsing process and a dehydration process are performed. In the dehydration process, after the rinsing process is completed, the drain valve 31 is opened and the rotary drum 4 is gradually rotated at a high speed by the driving means 10. Moisture contained in the laundry 5 is separated by centrifugal force at high speed, discharged from the discharge hole 8 to the outside of the rotating drum 4, and discharged from the drain port 32 to the outside of the housing 2.

  In the dehydration process, the rotational speed of the rotating drum 4 is controlled so that the laundry 5 is uniformly attached to the peripheral wall surface of the rotating drum 4 before the rotating drum 4 is started at high speed. At this time, since the twist and entanglement of the laundry 5 are suppressed in the washing process and the rinsing process, which are the processes before the dehydration process, the laundry 5 tends to be uniform. Therefore, even if the rotary drum 4 is rotated at a high speed, vibration is suppressed and a reduction in noise can be realized.

  Next, a drying process is performed. The laundry 5 is agitated in the rotating drum 4 by the rotation of the driving means 10. At the same time, the blowing means 20 and the heating means 21 are energized, and the heated drying air is supplied from the supply port 23 to the outer tub 1 and supplied from the outlet 25 and the outlet 13a toward the rotating drum 4 and the laundry 5 Contact with.

  The rotating drum 4 is inclined so that the clothing input port 6 side becomes higher, and the rotation of the rotating drum 4 causes the movement of the laundry 5 to the corrector 13 disposed on the bottom wall surface side of the rotating drum 4. The drying air that is biased and blown out from the outlet 25 and the outlet 13a is in good contact with the laundry 5 and is then discharged from the outlet hole 8 of the rotating drum 4. The discharged drying air flows into the circulation wind tunnel 22 from the intake port 24, is heated by the heating means 21, and is supplied to the rotary drum 4 from the blowout port 25 and the blowout port 13a again.

  When the temperature of the drying air rises and reaches a predetermined temperature, cooling water is supplied to the cooling water supply port 28. The supplied cooling water cools the heat exchanger 29 and dehumidifies moisture from the humid drying air flowing through the circulating wind tunnel 22.

  Similar to the washing process, the laundry 5 is lifted upward by the centrifugal force of the rotating drum 4 and the action of the stirring baffle 9 and falls from the upper part. When the laundry 5 is biased toward the bottom wall surface of the rotating drum 4, the corrector 13 moves in the same manner as the laundry 5 when the laundry 5 is dropped. Accordingly, the laundry 5 present at the bottom of the rotating drum 4 has the same rotational speed of the laundry 5 present at the inlet 6 side and the bottom of the rotating drum 4, and the twist of the same laundry 5 and the laundry, Since the entanglement is suppressed, the drying air contacts the laundry 5 evenly, so there is no unevenness in drying, improving the drying efficiency, saving energy, shortening the drying time, and achieving a good finish with fewer wrinkles on clothes. it can.

  As described above, in the present embodiment, the outer tub 1 includes the bottomed cylindrical rotary drum 4 in which the charging port 6 is inclined forward and inclined, and the driving means 10 that rotates the rotary drum 4. The correction body 13 for correcting the movement of the laundry 5 is provided so that the movement of the laundry 5 located at the bottom of the rotary drum 4 and the movement of the laundry 5 on the loading port 6 side of the rotary drum 4 are the same. Thus, the laundry 5 present at the bottom of the rotary drum 4 accompanying the rotation of the rotary drum 4 has the same rotational speed as the laundry 5 present at the inlet 6 side and the bottom of the rotary drum 4 has the same rotational speed. Since the twist and entanglement between the laundry 5 are suppressed, the washing action acts on the entire laundry 5, so washing with less washing unevenness and high washing power can be realized. Further, since the twist and entanglement between the laundry 5 and the laundry 5 are suppressed, vibration during dehydration is minimized, and high-speed dehydration can be realized with low noise. In addition, the drying time can be shortened and a good finish with less wrinkles can be realized.

(Embodiment 2)
FIG. 5 is a cross-sectional view of a drum-type washing / drying machine according to a second embodiment of the present invention, FIG. 6 is a plan view of the main part of the drum-type washing / drying machine, and FIG. The partial sectional view is shown, and the same constituent elements as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

A correction body 13 is disposed at the bottom of the rotating drum 4 and is supported by the rotation axis of the driving means 10. The rotary shaft 12 is integrally fixed to the extension portion 12a. The correction body 13 is provided with a resistance reducing body 33 that reduces frictional resistance with the laundry 5. The resistance reducing body 33 is a cylindrical rotating body, and is supported by a shaft mounting body 35 of the correcting body 13 so as to be rotatable about a rotating shaft 34. Further, the resistance reducing body 33 is constituted by a plurality of rotating bodies partially protruding from the surface of the correction body 13. Further, the set of rotating bodies formed in the resistance reducing body 33 radially is divided into a plurality of resistance reducing members 35a, 35b, 35c, and 35d.

  As described above, by arranging the resistance reducing body 33 in which the pair of rotating bodies is divided into a plurality of parts in the correcting body 13, the laundry is naturally stirred in the rotating drum 4 in the washing process and the drying process. The laundry 5 is lifted upward by the centrifugal force generated by the rotation of the rotating drum 4 and the stirring baffle 9, and when the laundry reaches the upper part, the weight of the laundry 5 is released over the centrifugal force and falls. At this time, the laundry 5 present at the bottom of the rotating drum 4 has different moving speeds between the outer peripheral portion and the inner peripheral portion of the rotating drum 4. The outer peripheral portion falls at a faster moving speed than the inner peripheral portion. The resistance reducing member 33a on the outer peripheral portion of the divided resistance reducing body 33 is fast and the resistance reducing member 33d on the inner peripheral portion rotates slowly, so that it can naturally rotate in response to the speed difference. Drop movement is performed.

  On the other hand, the laundry 5 existing on the input side 6 of the rotary drum 4 has the rotary drum 4 inclined forward (inclination θ shown in FIG. 6). The frictional force is small. Accordingly, the rotational speeds of the rotating drum 4 on the laundry 5 side of the laundry 5 and the bottom are the same, and the laundry 5 and the laundry 5 are prevented from being twisted and entangled.

  Further, since the resistance reducing body 33 is configured to partially protrude from the surface of the correction body 13, the laundry 5 is wound around the resistance reduction body 33, and there is no biting between the surface of the correction body 13 and the resistance reduction body 33. When the entire surface of the correction body 13 becomes a low friction surface and the laundry is lifted, natural movement is given to all the movements including when the laundry is dropped.

  As described above, in the present embodiment, the correction body 13 is provided with the resistance reduction body 33 that reduces the frictional resistance with the laundry 5, so that the frictional resistance between the laundry 5 and the correction body 13 is reduced. Since the lifting of the laundry 5 by the rotation of the rotating drum 4 is governed by the centrifugal force of the rotating drum 4 and the action of the stirring baffle 9, the movement of the rotating drum 4 on the inlet 6 side and the bottom side becomes the same, Twist of the article 5 and entanglement between the laundry 5 are improved. As a result, since the washing action acts on the whole laundry 5, washing with less washing unevenness and high washing power can be realized. In addition, vibration during dehydration is minimized, and high-speed dehydration can be realized with low noise. In addition, the drying time can be shortened and a good finish with less wrinkles can be realized.

  According to the present embodiment, the correcting body 13 is fixed to the extension 12a of the rotating shaft 12 at the bottom of the rotating drum 4. However, the correcting body 13 is freely rotatable as in the first embodiment. The same effect can be obtained even if it is pivotally supported.

  Moreover, according to this Embodiment, although the resistance reduction body 33 is comprised with the rotating body which comprised the column shape, even if comprised with the rotating body of the spherical body rotated to a free direction, there can exist the same effect. it can.

  As described above, the drum-type washing machine or the washing dryer according to the present invention uniformly stirs the laundry of the rotating drum so that there is little drying unevenness, the drying time is shortened, the drying rate is high, and energy saving is possible. Therefore, the present invention can be applied to a garbage disposal machine that requires drying.
