  The present invention relates to a laundry dewatering and drying apparatus.

2. Description of the Related Art A laundry dewatering / drying apparatus that performs washing, dewatering and drying of laundry has been proposed. In such a laundry dewatering and drying apparatus, hot air for drying the laundry is blown into the inner tub from the direction of the rotation axis of the inner tub that is rotationally driven, and is discharged in the circumferential direction of the inner tub.
A clothes dryer for drying laundry is proposed in Patent Document 1 below. In the clothes dryer described in Patent Document 1, a heater and a cooler for drying clothes are provided below the rotating drum so as to be adjacent to the rotating shaft of the rotating drum. Then, on the outer peripheral surface of the rotating drum in the vicinity of the rotation axis direction center of the rotating drum, a sliding member for closing a radial gap between the rotating drum and the drying chamber incorporating the rotating drum is provided, The drying chamber is divided into two by the sliding member in the rotation axis direction of the rotating drum. Thereby, the hot air from the heater is blown into the inner tank from one of the two drying chambers and is discharged toward the cooler from the other of the two drying chambers.
Japanese Patent Laid-Open No. 3-186296

  The conventionally proposed laundry dewatering and drying apparatus needs to form an air passage for hot air in the direction of the rotation axis of the inner tub, and the case size of the laundry dewatering and drying apparatus is increased. In addition, when hot air is blown from the door side provided in the rotation axis direction, the temperature of the door becomes high, so the maximum temperature of the hot air must be set low, and in this case, the drying time is prolonged. There is a risk that deterioration of the drying efficiency due to the above will not be avoided.

In the clothes dryer described in Patent Document 1, the drying chamber is divided into two in the direction of the rotation axis of the rotary drum by the sliding member, and the hot air from the heater is below one of the two drying chambers. From the other side and discharged to the cooler. Therefore, it is not necessary to form a hot air path in the direction of the rotation axis of the rotary drum, and the increase in the size of the casing described above can be suppressed.
However, in some laundry dehydration and drying apparatuses, a water channel is disposed at the lower part of the inner tub (rotating drum), and in this case, consideration is required for the arrangement of the heater and the cooler. In addition, the laundry dewatering / drying apparatus that performs washing, dewatering, rinsing, and drying operations has a longer operation time than an clothes dryer (only drying operation), and therefore the rotation time of the inner tub is inevitably longer. Therefore, it is necessary to take measures against wear on the sliding member that is always in sliding contact with either the inner tank or the drying chamber (outer tank).

An object of the present invention made based on such a background is to provide a laundry dewatering and drying apparatus in which an increase in the size of a housing is suppressed.
Another object of the present invention is to provide a washing / dehydrating / drying apparatus capable of improving the drying efficiency.
Still another object of the present invention is to provide a laundry dewatering and drying device in which wear of a sliding member provided between an inner tub and an outer tub is reduced.

  The invention according to claim 1 is a cylindrical body having an opening on the front side of the cylindrical body, and an inflow port for allowing air to flow into the upper part on the back side of the cylindrical body, An outer tank having an outlet for allowing air to flow out at the upper part on the front side of the cylindrical body, and a cylindrical body provided in the outer tank, having an opening on the front side and penetrating the cylindrical body An inner tub in which laundry can be taken in and out from an opening on the front side, a door provided to open and close the opening of the outer tub and the opening of the inner tub, Driving means for rotating the tank, heating means for heating air, and blowing / exhaust means for blowing the heated air into the inner tank through the inlet and exhausting through the outlet The heated air flows into the inner tank from the inlet and flows out from the outlet. In the middle of the front side and the back side of the outer tub, a sealing member that closes a gap between the inner peripheral surface of the outer tub and the outer peripheral surface of the inner tub facing each other, and washing operation for washing laundry, A laundry dehydrating and drying apparatus capable of performing a dehydrating operation for dehydrating laundry and a drying operation for drying laundry.

According to a second aspect of the present invention, the inflow port is spaced apart from the rotation axis of the inner tub in the orthogonal direction so as not to be blocked by the laundry in the inner tub being rotationally driven. The laundry dewatering and drying apparatus according to claim 1, wherein
The invention according to claim 3 is characterized in that the outlet is disposed on the opposite side of the inlet with respect to the rotation axis of the inner tub in a top view. It is a drying device.

  According to a fourth aspect of the present invention, the seal member includes a member whose shape changes according to an ambient temperature and an elastic member that covers the member whose shape changes, and the ambient temperature in the washing operation and the dehydrating operation is A gap is formed between the outer tank and the inner tank in the radial direction, and the gap is closed when the ambient temperature rises in the drying operation. It is a laundry dehydration drying apparatus of description.

  The invention according to claim 5 is the laundry dewatering and drying apparatus according to claim 4, wherein the member whose shape changes is formed of a shape memory alloy.

  According to the first aspect of the present invention, the heated air generated by the heating means becomes hot air by the blower / exhaust means and flows into the inner tub from the inlet formed in the upper part on the back side of the outer tub. After exchanging heat with the object, it flows out to the outside from an outlet formed in the upper part on the front side of the outer tub. Thereby, the dimension of the casing in the direction of the rotation axis, that is, the depth, can be reduced as compared with the case where the air path for flowing hot air from the back side or the front side of the outer tank to the rotation axis direction of the inner tank is formed. Moreover, when this hot air moves from the back side to the front side, it exchanges heat with the laundry, and the temperature decreases. For this reason, the door provided on the front face is exposed to hot air having a lowered temperature, so that the temperature is not high, and the limitation on the maximum temperature of the hot air and the accompanying increase in drying time are eliminated.

Since the hot air inlet and outlet are provided in the upper part of the outer tank, the heating means and the air blowing / exhausting means can also be arranged above the outer tank, and the above-mentioned water channel is arranged in the space below the outer tank. It becomes possible.
Since the gap between the inner peripheral surface of the outer tub and the outer peripheral surface of the inner tub facing each other is closed by the seal member, all of the hot air can flow into the inner tub from the inflow port. Improvement is possible.

According to invention of Claim 2, since an inflow port is not obstruct | occluded with laundry, a hot air can flow in into an inner tank smoothly from an inflow port, and the further improvement of the drying efficiency of laundry is possible. Become.
According to the invention of claim 3, on the opposite side to the rotation axis of the inflow port arranged in the orthogonal direction from the rotation axis of the inner tub in the top view so as not to be blocked by the laundry, Since the outlet is disposed, the distance between the inlet and the outlet can be increased. Therefore, the moving distance of the hot air from the inflow port to the outflow port is increased, and the laundry can be sufficiently exposed to the hot air, so that the drying efficiency of the laundry can be further improved.

  According to the invention described in claim 4, the member whose shape changes depending on the ambient temperature forms a gap between the outer tub and the inner tub in the radial direction at the ambient temperature in the washing operation and the dehydrating operation. Therefore, the seal member does not slide with respect to the outer tank or the inner tank. On the other hand, in the drying operation, the member whose shape changes is deformed so as to close the gap described above by the ambient temperature higher than the ambient temperature in the washing operation and the dehydration operation, and the sealing member is Slide. Thus, since the seal member slides relative to the outer tank or the inner tank only in the drying operation, wear of the seal member can be reduced. Further, in this sealing member, the elastic member covering the member whose shape is changed slides following the shape with respect to the outer tank or the inner tank, so that the gap described above can be reliably closed. . Moreover, since it is an elastic member, it can contribute to the reduction of the abrasion at the time of sliding.

  According to the fifth aspect of the present invention, since the member whose shape changes is a shape memory alloy, the restoration property is high, and the shape in the washing operation and the dehydration operation and the shape in the drying operation are surely maintained. be able to.

The water accumulated in the outer tub 12 enters the rotating drum tub 13 through a large number of holes 24 formed in the peripheral surface plate 21 of the rotating drum tub 13, and the water levels in the rotating drum tub 13 and the outer tub 12 become substantially equal. .

A drain outlet 50 is formed at the lowest position in the outer tub 12, and one end of a drain pipe 51 is connected to the drain outlet 50. The other end of the drain pipe 51 extends outside the machine. A drain valve 52 is inserted in the middle of the drain pipe 51. When the drain valve 52 is opened, the water stored in the rotary drum tank 13 and the outer tank 12 is discharged outside the machine through the drain pipe 51.
In addition, an overflow is provided above the rear end face plate 29 of the outer tub 12 to overflow the predetermined amount of water to the outside of the outer tub 12 when a predetermined amount of water is supplied into the outer tub 12. One end of the tube 38 is connected. The overflow pipe 38 extends downward through the rear of the outer tub 12, and the other end is connected to the middle part of the drain pipe 51 (downstream side of the drain valve 52). The water overflowing from the outer tub 12 to the overflow pipe 38 is discharged outside the machine through the drain pipe 51.

  A drying air passage 66 is formed above the rear side of the outer tub 12. The drying air passage 66 communicates with the outside of the housing 11 through an intake port 77 formed on, for example, the back surface of the housing 11, and a heater 68 as a heating unit is disposed inside. The heater 68 is, for example, a gas heater that burns a gas supplied from a gas supply path (not shown) and heats the surrounding air with the combustion heat.

  An inlet 71 for communicating the drying air passage 66 with the inside of the outer tub 12 is formed on the inner peripheral surface of the upper part of the outer tub 12, and on the axially front side of the rotary shaft 14 from the inlet 71. An annular seal member 72 is fitted on the rotary drum tank 13. As shown in FIG. 4, the sealing member 72 is formed by coating an elastic member 83 such as rubber on a skeleton 65 as a member having a substantially U-shaped side sectional view and a shape-changing shape formed of a shape memory alloy. In a state of being externally fitted to the rotating drum tank 13, it is formed so as to form a gap in the radial direction with the outer tank 12 at room temperature. The seal member 72 will be described in detail later.

  As shown in FIG. 1, an outlet 76 is formed on the inner peripheral surface of the upper portion of the outer tub 12 on the axial front side of the rotating shaft 14 relative to the seal member 72. Via this outflow port 76, the inside of the outer tub 12 communicates with an exhaust air passage 79 for exhausting air in the outer tub 12 via an exhaust port 78 connected to a duct (not shown) communicated outdoors. Has been. The exhaust air passage 79 is formed above the front side of the outer tub 12, and a fan 67 serving as a blower / exhaust means is disposed therein.

Next, a washing operation, a rinsing operation, and a drying operation will be described for the driving method of the drum type washing machine 10 (how to wash using the drum type washing machine 10).
(1) Washing operation The user opens the lid 19, puts detergent and laundry into the rotating drum tank 13, and closes the lid 19. The detergent may be supplied into the rotating drum tank 13 at a predetermined timing by a detergent supply means (not shown). When a start button (not shown) is pressed, the drum type washing machine 10 starts the following washing operation.

  The water supply valve 37 is opened, and cleaning water is supplied to the outer tub 12 through the main water supply pipe 33 and the water supply hole 35. At this time, the drain valve 52 is closed, and cleaning water accumulates in the outer tank 12 and the rotating drum tank 13. After a predetermined amount of cleaning water is supplied, the water supply valve 37 is closed, and the rotary drum tank 13 is rotated by the motor 26. Along with this rotation, the laundry in the rotary drum tank 13 is lifted by the baffle 25, dropped, and washed.

After completion of the washing, the drain valve 52 is opened, and the washing water in the outer tub 12 is drained outside the machine through the drain pipe 51. After the washing water is drained, the rotating drum tank 13 is dehydrated and rotated (high-speed rotation) by the motor 26, and a dehydration operation is performed in which the washing water contained in the laundry is dehydrated.
(2) Rinsing operation The drain valve 52 is closed, the water supply valve 37 is opened, and a predetermined amount of rinsing water is supplied to the outer tub 12 through the main water supply pipe 33 and the water supply hole 35. Then, the rotating drum tub 13 is rotated by the motor 26, and the laundry in the rotating drum tub 13 is rinsed. After the rinsing is completed, the drain valve 52 is opened, and the rinsing water after the rinsing in the outer tub 12 is completed is drained outside the machine through the drain pipe 51.

After the rinse water in the outer tub 12 is drained, the above-described dehydration operation is performed, and the rinse water contained in the laundry is dehydrated. This water is also discharged outside the aircraft. The dirt component discharged from the drain pipe 51 to the outside of the machine may be captured by a filter or the like and processed as waste or garbage. The rinsing operation is normally performed twice, but a rinsing operation may be added if necessary.
(3) Drying operation After the dehydration operation is completed, the drying operation is performed. In the drying operation, the rotary drum tank 13 is dried and rotated by the motor 26, and the fan 67 is turned on, and the outer tank 12, the rotary drum tank 13, the drying air passage 66, and between the fan 67 and the outlet 76. The inside of the exhaust air passage 79 in the range becomes negative pressure. Therefore, air outside the machine is sucked into the dry air passage 66 from the intake port 77. When this air passes through the heater 68 turned on simultaneously with the fan 67, it is heated and becomes hot air. The hot air flows into the outer tub 12 from the inlet 71 through the drying path 66, and flows into the rotary drum tub 13 through the hole 24. The hot air exchanges heat with the laundry in the rotary drum tank 13 to vaporize moisture contained in the laundry, and then passes through the exhaust air passage 79 via the outlet 76 together with water vapor. From 78, it is discharged out of the machine. In addition, since the air containing moisture is discharged | emitted by the said duct connected to the exhaust port 78 to the outdoors, there is no possibility that moisture may accumulate in the room | chamber in which the drum type washing machine 10 is arrange | positioned.

The feature of the drum type washing machine 10 according to this embodiment is that it includes the arrangement positions of the inflow port 71 and the outflow port 76 and the seal member 72, which will be described in detail below.
As described above, the inflow port 71 is located on the back side of the seal member 72, and the inflow port 71 is the upper part of the peripheral surface of the outer tub 12, and is formed on the right side when viewed from the front. And the outflow port 76 is located in the front side rather than the sealing member 72, and the outflow port 76 is the upper part of the surrounding surface of the outer tank 12, Comprising: It forms in the left side seeing from the front.

  As a result, the inlet 71 or the outlet 76 is provided on the back surface or the front surface of the outer tub 12, and the inlet or outlet in the depth direction is formed in comparison with the case where an air passage for blowing hot air in the axial direction of the central shaft 14 is formed. Since the space for disposing the outlet is unnecessary, the depth can be reduced. Moreover, when this hot air moves from the back side to the front side, it exchanges heat with the laundry, and the temperature decreases. Therefore, the lid 19 provided on the front surface is exposed to hot air having a lowered temperature, so that the temperature is not high, and the limitation on the maximum temperature of the hot air and the accompanying increase in drying time are eliminated. Further, by disposing the fan 67, the heater 68, and the like above the outer tub 12, it is possible to dispose the drain pipe 52 and an additional water channel below the outer tub 12.

  Further, as described above, the sealing member 72 has a substantially U-shaped side sectional view, and as shown in FIG. 4A, the mounting wall 81 and the mounting wall connected to the outer peripheral surface of the rotary drum tank 13 A pair of movable walls 82 are provided so as to face each other from both end edges of 81 and toward the inner peripheral surface of the outer tub 12. The pair of movable walls 82 are arranged so that their free end portions are separated from each other at normal temperature, that is, ambient temperature in the washing operation, the rinsing operation, and the dehydrating operation. A gap is formed in the radial direction. Then, at a high ambient temperature in the drying operation, as shown in FIG. 4 (b), the pair of movable walls 82 move so that their free ends approach each other, and these free ends are located in the outer tub. 12 in contact with the inner peripheral surface. Thereby, the sealing member 72 closes the above-described gap, and the outer tub 12 is divided into two parts between the front side and the back side as shown in FIG.

Therefore, the hot air from the inlet 71 can flow into the rotary drum tank 13 from the inlet 71 without leaking from the gap and flowing directly into the outlet 76 without flowing into the rotary drum tank 13 (FIG. It is possible to improve the drying efficiency of the laundry.
Further, as described above, since the seal member 72 is formed of a shape memory alloy, it has a high resilience, and the shape in the washing operation, the rinsing operation, and the dehydration operation and the shape in the drying operation are each ambient temperature. It can be reliably maintained according to.

  Further, as described above, the rotating drum tank 13 is rotating in the washing operation, the rinsing operation, the dehydrating operation, and the drying operation. As shown in FIG. 4, the seal member 72 is not slid with respect to the outer tub 12 because it forms a gap in the radial direction with the outer tub 12 in the washing operation, the rinsing operation, and the dehydrating operation, and thus the drying operation. Only, the gap is closed and the outer tank 12 is slid. Therefore, the wear of the seal member 72 can be reduced as compared with the case where the seal member 72 is always sliding with respect to the outer tub 12. Since the seal member 72 is formed by coating the elastic member 83 such as rubber on the shape memory alloy framework 65, the seal member 72 slides on the outer tub 12 following the shape of the inner peripheral surface thereof. can do. Therefore, the gap described above can be reliably closed. Further, the elastic member 83 forming the surface of the seal member 72 contributes to reduction of wear during sliding. In the washing operation, the rinsing operation, and the dehydrating operation, the seal member 72 forms a gap with respect to the outer tub 12 as described above. Therefore, when the water used for each operation is drained from the drain port 50. All of these waters can reach the drain port 50 (see FIG. 1) through the gaps described above, and do not remain in the outer tub 12. In this embodiment, as shown in FIG. 1, the drainage port 50 is divided into a drainage port 50 a on the front side and a drainage port 50 b on the back side with respect to the seal member 72, thereby providing an outer tub during drainage. All the water in 12 is surely drained out of the machine from the drain port 50a and the drain port 50b.

In the left-right direction, as shown in FIGS. 2 and 3, the inflow port 71 is disposed on the right side and the outflow port 76 is disposed on the left side with respect to the radial center of the outer tub 12 (that is, the central axis 14). ing. Therefore, as shown in FIG. 2, the line connecting the inlet 71 and the drying air passage 66 with the outlet 76 and the exhaust air passage 79 obliquely intersects the central axis 14 in a top view.
Thereby, the space | interval of the inflow port 71 and the outflow port 76 can be lengthened compared with the case where the inflow port 71 and the outflow port 76 oppose and arrange | position so that the line mentioned above may orthogonally cross the rotating shaft 14. FIG. Therefore, the moving distance of hot air from the inflow port 71 to the outflow port 76 in the drying operation is increased, and the laundry 80 can be sufficiently exposed to hot air, so that the drying efficiency of the laundry can be improved. .

  As shown in FIG. 3, the rotating direction of the rotating drum tank 13 is the direction of the arrow shown in the figure (clockwise), so the laundry 80 is rotated in the same direction of the arrow by the baffle 25 as the rotating drum tank 13 rotates. It falls by its own weight before reaching the inflow port 71. Therefore, the laundry 80 always moves away from the inflow port 71 during the rotation of the rotary drum tank 13, so there is no possibility that the laundry 80 will block the inflow port 71. Therefore, the hot air from the heater 68 can smoothly flow into the rotary drum tank 13 from the inlet 71, and the drying efficiency of the laundry 80 can be further improved.

  The present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the claims.
