  By the way, the drum may be swung around by being rotated at a high speed during dehydration and may come into contact with surrounding members. Since noise occurs when the drum and peripheral members come into contact with each other, a predetermined space is provided between the drum and the peripheral members. Therefore, when the seal member is provided in the drum or the water tank, it is necessary to provide a predetermined space between the seal member and the water tank or the drum in consideration of the fact that the drum sways during the dehydration. However, when there is a space around the seal member in this way, there is a possibility that warm air may pass through the seal member and enter the space between the water tank and the drum.

The seal member has a lip portion that extends toward the opening and inclines toward the rotating tub, and when the rotating tub rotates at a low speed, the tip of the lip portion is on the outer peripheral surface of the opening. The lip portion is elastically deformed so that the tip of the lip portion is separated from the opening when the rotating tank is driven to rotate at a high speed.

  According to the present invention, the warm air that has flowed into the water tank during the drying operation passes through the air guide path and flows into the rotating tank through the opening and the hot air intake. At this time, the air leaking from between the opening and the hot air intake is prevented from entering the space between the water tank and the rotating tank by the sealing member. Further, since the tip of the sealing member is configured to be separated from the opening when the rotating tub rotates at a high speed, it is possible to prevent generation of noise and wear of the lip.

  A drying device 30 as hot air supply means is installed on the upper part of the water tank 3. The drying device 30 includes a ventilation duct 31, a blower fan 32 disposed in a front portion of the ventilation duct 31, and a heater 33 disposed in a central portion of the ventilation duct 31. The rotating shaft 32 a of the blower fan 32 passes through the ventilation duct 31 and protrudes above the ventilation duct 31, and is configured to be rotated by a fan motor 34 disposed on the upper surface of the ventilation duct 31.

  A hot air inlet 35 is formed at the upper rear end of the water tank 3, and a rear end portion of the ventilation duct 31 is connected to the hot air inlet 35. On the other hand, a hot air outlet 36 is formed at the lower part of the front end portion of the water tank 3, and the front end portion of the ventilation duct 31 is connected to the hot air outlet 36 via an exhaust duct 37.

  The exhaust duct 37 is curved along the opening 24 of the water tank 3, and a water injection pipe (not shown) is provided on the upper portion thereof. The water injection pipe is configured to inject the water supplied from the water supply device 27 via a water injection hose (not shown) into the exhaust duct 37 in the form of a shower.

  Next, the hot air intake structure provided between the hole 11 at the rear end of the rotating tub 4 and the hot air inlet 35 will be described with reference to FIGS. 1 to 6. A duct cover 41 is attached to the front surface of the rear end of the water tank 3. The duct cover 41 includes a straight portion 41 a extending downward from the peripheral portion of the hot air inlet 35 and an annular portion 41 b positioned in the peripheral portion of the bearing 7. A cylindrical portion 42 protruding toward the rotating tub 4 is provided at the inner peripheral edge of the annular portion 41b.

A flange 43 is provided over the entire outer peripheral edge of the duct cover 41, and the flange 43 is screwed to the front surface of the rear end of the water tank 3. At this time, the rotating shaft 8 is separated from the cylindrical portion 42, and a communication port 44 (corresponding to an opening) is formed between the rotating shaft 8 and the cylindrical portion 42. With the above configuration, the air guide path 45 extending from the hot air inlet 35 toward the communication port 44 is formed between the rear end portion of the water tank 3 and the duct cover 41.
The cylindrical portion 42 is located on the inner periphery of the seal holding portion 13 a of the reinforcing member 12. In other words, a part of the outer peripheral surface of the cylindrical part 42 and a part of the inner peripheral surface of the seal holding part 13a are configured to face each other in the radial direction with a predetermined interval.

  On the other hand, as shown in FIGS. 1 and 4 to 6, a plurality of, for example, 12 radially extending portions between the shaft mounting portion 15 and the peripheral wall portion of the base portion 13 among the base portion 13 of the reinforcing member 12. Fins 46 are provided. With the above configuration, a substantially fan-shaped space is formed between adjacent fins 46. A hot air intake 47 is formed on the rear surface of the base portion 13 corresponding to half of the 12 fan-shaped spaces. The fan-shaped space having the hot air intake 47 and the fan-shaped space having no opening are alternately arranged.

  Further, as shown in FIGS. 2 and 3, an annular seal member 50 is attached to the seal holding portion 13 a of the base portion 13. The seal member 50 is made of a flexible elastic member such as rubber, and has a cylindrical base portion 51, a locking portion 52 protruding in a substantially right angle direction from the rear end of the inner peripheral surface of the base portion 51, The lip portion 53 extends obliquely forward from the front end of the locking portion 52. With such a configuration, the seal member 50 has a substantially V-shaped cross section. The seal member 50 is formed by fitting the base portion 51 into the outer peripheral portion of the seal holding portion 13 a of the reinforcing member 12 and then press-fitting a metal annular fixing fitting 54 into the outer peripheral portion of the base portion 51. It is fixed to the seal holding part 13a. At this time, the locking portion 52 is locked to the rear end surface of the seal holding portion 13a. Further, the tip of the lip 53 is slightly separated from the cylindrical portion 42 of the duct cover 41.

  When the rotating tub 4 is driven to rotate, centrifugal force is applied to the lip portion 53. The magnitude of the centrifugal force is proportional to the mass of the lip 53, the distance from the rotation center of the rotating tub 4 to the lip 53, and the square of the rotational speed of the rotating tub 4. Therefore, when the rotational speed of the rotating tub 4 increases, the centrifugal force applied to the lip portion 53 increases accordingly. In the present embodiment, the tip of the lip 53 is close to the cylindrical portion 42 during the washing process and the drying process in which the rotating tub 4 rotates at a low speed, but during the dehydrating process in which the rotating tub 4 rotates at a high speed. The lip portion 53 is elastically deformed in the radial direction by the centrifugal force acting on the lip portion 53 and is separated from the cylindrical portion 42.

  Next, the operation of the above configuration will be described. In the washing and drying machine 1, when a standard operation course is started, first, the motor 6 is energized in a predetermined energization mode, and the laundry weight as the motor load is determined based on the rotation speed of the motor 6 at this time. Detected. In the present embodiment, the lip portion 53 of the seal member 50 is configured to be separated from the cylindrical portion 42 when the rotating tub 4 is stopped. Therefore, the lip portion 50 does not become a motor load when the weight of the laundry is detected, and the weight of the laundry can be prevented from being erroneously detected.

  Subsequently, a washing process, a dehydration process, and a drying process are sequentially performed. In the washing process, the water supply device 27 is driven to perform an operation of supplying water into the water tank 3. When a predetermined amount of water corresponding to the amount of laundry is supplied into the water tank 3, the motor 6 is driven to rotate the rotating tank 4 in the forward and reverse directions at a low speed. At this time, since the centrifugal force acting on the lip portion 53 of the seal member 50 is small, the lip portion 53 is not elastically deformed and is in a state close to the duct cover 41.

  In the dehydration process, after the water in the water tank 3 is discharged, an operation of rotating the rotating tank 4 in one direction at a high speed is performed. For this reason, the laundry in the rotating tub 4 is rotated while being attached to the inner surface of the peripheral wall portion of the rotating tub 4 and is centrifugally dehydrated. At this time, since the centrifugal force acting on the lip portion 53 is large, the lip portion 53 is elastically deformed and separated from the cylindrical portion 42 of the duct cover 41.

  In the drying process, the motor 6 rotates the rotating tub 4 in the forward and reverse directions at a low speed and starts driving the heater 33 and the fan motor 38. In addition, water is injected from the water supply device 27 into the exhaust duct 37 through the water injection pipe. As a result, the air in the water tank 3 flows from the hot air outlet 36 through the exhaust duct 37 into the ventilation duct 31 by the air blowing action of the blower fan 32 and is heated by the heater 33, and then from the hot air inlet 35 into the water tank 3. Flow into.

  At this time, since the rotation speed of the rotating tub 4 is small and the centrifugal force acting on the lip portion 53 is small, the lip portion 53 is not elastically deformed and is in a state of being close to the duct cover 41. For this reason, much of the air (warm air) that has flowed into the air guide path 45 in the water tank 3 from the hot air inlet 35 passes through the communication port 44 without going to the space between the rotary tank 4 and the water tank 3. It goes to the wind inlet 47 and flows into the rotary tank 4 from the hole 11.

  The warm air that has flowed into the rotary tub 4 deprives the laundry of moisture, and then flows into the exhaust duct 37 from the warm air outlet 36. And after cooling and condensing by the water injected from a water injection pipe | tube, it dehumidifies, and after passing through the ventilation fan 32 and the heater 34, it returns in the rotary tank 4. The laundry in the rotating tub 4 is dried by such air circulation.

  According to the above configuration, the following effects can be obtained. That is, when a flexible seal member 50 is provided on the outer periphery of the air guide path 45 provided in the water tank 3 and the rotary tank 4 is driven to rotate at a low speed during the drying process, the lip portion of the seal member 50 is provided. 53 is configured to be close to the cylindrical portion 42. Therefore, it is possible to prevent the air from the air guide passage 45 through the communication port 44 toward the hot air intake port 47 from entering the space between the rotary tank 4 and the water tank 3. For this reason, most of the warm air that has flowed into the water tank 3 from the warm air inlet 40 can be guided into the rotating tank 4, and the drying efficiency can be improved.

  In particular, in this embodiment, the cylindrical portion 42 constituting the communication port 44 and the seal holding portion 13a provided with the seal member 50 are opposed to each other in the radial direction to form a labyrinth structure, and the seal member 50 is provided at that portion. The seal member 50 can prevent warm air from entering the space between the water tank 3 and the rotating tank 4 and also the space between the water tank 3 and the rotating tank 4 by the cylindrical portion 42 and the seal holding portion 13a of the labyrinth structure. It is possible to prevent warm air from entering the space.

  Further, the lip portion 53 falls apart from the duct cover 61 by the centrifugal force when the rotating tub 4 rotates at a high speed during the dehydration process. Therefore, even if the tip of the lip 53 is close to the cylindrical portion 42 when the rotating tub 4 is stopped, the lip 53 and the cylindrical portion 42 do not come into contact with each other during the dehydration process. For this reason, generation | occurrence | production of the noise by the lip part 53 and the duct cover 61 contacting and wear of the lip | rip part 53 can be suppressed as much as possible. In addition, in this embodiment, the communication port 44 and the hot air intake port 47 are provided in the vicinity of the rotary shaft 8, and the inner periphery of the seal holding portion 13 a provided in the base portion 13 having the hot air intake port 47 is provided. A seal member 50 was provided. The distance when the rotating tub 4 rotates and swings at a high speed is smaller in the vicinity of the rotating shaft 8. Therefore, even when the rotating tub 4 that rotates at a high speed during the dehydration step is swung, it is possible to prevent the lip portion 53 from contacting the cylindrical portion 42 as much as possible.

  Further, the lip portion 53 is configured to fall away from the cylindrical portion 42 in the radial direction when the rotating tub 4 rotates at high speed. By adopting such a configuration, even when the roundness of the seal member 50 is low or when the seal member 50 and the rotation center of the rotary tank 4 do not coincide with each other, the seal member 50 The cylindrical portion 42 can be reliably separated.

  The seal member 50 is a groove-shaped member having a V-shaped cross section, and the groove-shaped member opens on the upstream side of the air flow to be leaked into the space between the rotary tank 4 and the water tank 3. Therefore, the seal member 50 has a great resistance to the air flow to be leaked, and the air can be further prevented from leaking. In addition, when the clothes in the rotating tub 4 are dried and swelled and it becomes difficult for air to enter the rotating tub 4, the seal member 50 receives the air from the rotating tub 4 and swells backward. Then, since the tip of the lip portion 53 is closer to the cylindrical portion 42, it is possible to prevent air from leaking out.

  By the way, in the assembly process of the washing / drying machine, after the bearing 7 is attached to the water tub 3 and the shaft 7 is supported by the bearing 7, the rotation is performed with the seal member 50 attached to the seal holding portion 13 a of the reinforcing member 12. The tank 4 is inserted from the front, and the center of the rear surface of the rotating tank 4 is screwed to the front end of the rotating shaft 8. At this time, since the opening of the seal member 50 faces forward, the lip portion 53 is not caught by the cylindrical portion 42 when the seal holding portion 13 a is inserted into the outer periphery of the cylindrical portion 42.

On the other hand, FIGS. 7 to 9 show second to fourth embodiments in which the shape of the seal member and the attachment method of the seal member are different.
First, a sealing member 60 according to the second embodiment of the present invention shown in FIG. 7 includes a cylindrical base portion 61, a lip portion 62 extending obliquely forward from the rear end of the inner peripheral surface of the base portion 61, The metal ring 63 is fixed to the outer peripheral surface of the base portion 61. The metal ring 63 is fixed to the outer peripheral surface of the base portion 61 by, for example, baking.
The seal member 60 is press-fitted into the inner peripheral surface of the seal holding portion 13a. At this time, the tip of the lip portion 62 is close to the outer peripheral surface of the cylindrical portion 42 of the duct cover 41.
Even in such a configuration, the same operation and effect as in the first embodiment can be obtained.

  FIG. 8 shows a third embodiment of the present invention, which differs from the second embodiment in the following points. That is, the sealing member 60 according to the present embodiment is provided with a bent portion 64 that bends forward at the tip of the lip portion 62. The bent portion 64 is in light contact with the cylindrical portion 42 of the duct cover 41 when the rotating tub 4 is stopped and rotated at a low speed. On the other hand, when the rotating tub 4 rotates at a high speed, the lip portion 62 falls due to centrifugal force, so that the bent portion 64 is separated from the cylindrical portion 42.

According to the said structure, it can prevent substantially reliably that the warm air which goes to the warm air intake port 47 from the communicating port 44 at the time of a drying process enters into the space between the rotating tank 4 and the water tank 3. FIG.
In addition, a present Example is suitable for the washing-drying machine of the structure which measures the weight of the laundry in the rotating tub 4 with a weight sensor. In the configuration in which the weight of the clothes in the rotating tub is detected by the weight sensor, the weight of the laundry can be accurately detected even if the lip portion 62 and the cylindrical portion 42 are in contact at the time of low-speed rotation. is there.

  FIG. 9 shows a fourth embodiment of the present invention, which differs from the first embodiment in the following points. That is, in the fourth embodiment, a thick portion 71 is provided at the tip of the lip portion 53 that is thicker than other portions. By providing the thick portion 71, the centrifugal force acting on the tip of the lip portion 53 is increased as compared with the configuration in which the thick portion 71 is not provided. Therefore, the timing at which the lip 53 starts to fall when the motor 6 rotates at a high speed during the dehydration process can be advanced.

Next, fifth to tenth embodiments in which a water drainage hole is provided in the sealing member so that water adhering to the sealing member does not remain in the sealing member will be described.
Specifically, in the fifth embodiment of the present invention shown in FIG. 10, a plurality of drain holes 81 are provided at the boundary portion between the base portion 51 and the lip portion 53 of the seal member 50.
On the other hand, in the sixth embodiment of the present invention shown in FIG. 11, a plurality of drain holes 81 are provided at the front end portion of the base portion 61 of the seal member 60 and a plurality of holes corresponding to the drain holes 81 are provided. 82 is provided on the metal ring 63. Further, a hole 83 is provided in a portion of the reinforcing member 12 corresponding to the drain hole 81 and the hole 82, which is a base end portion of the seal holding portion 13 a. In any of the fifth and sixth embodiments, about eight to twelve drain holes 81 are provided.

  When water adheres to the seal member 60, most of the water is scattered when the rotating tub 4 rotates at a high speed during the dehydration process. However, the water adhering between the base portion 61 and the lip portion 62 of the seal member 60 remains difficult to scatter even when the rotating tub 4 rotates at a high speed. Thus, the water remaining between the base portion 61 and the lip portion 62 may become a resistance of the lip portion 62 that tends to fall by centrifugal force. On the other hand, according to the sixth or seventh embodiment described above, even if water adheres to the sealing member 61, the water can be discharged from the drain hole 81 or the like. Therefore, since the lip portion 62 can be reliably brought down when the rotating tub 4 rotates at a high speed in the dehydration step, it is possible to further prevent the generation of noise and the wear of the lip portion 62.

In the seventh embodiment of the present invention shown in FIG. 12, a plurality of drain holes 81 are provided at the boundary portion between the base portion 61 and the lip portion 53 of the seal member 60, and the inner peripheral surface of the base portion 51 is the front side. It is set as the inclined surface which inclines toward the said drain hole 81 side (outer peripheral side) toward back.
In the eighth embodiment shown in FIG. 13, a plurality of drain holes 81 are provided at the front end portion of the base portion 61 of the seal member 60, and the inner peripheral surface of the base portion 51 extends from the rear toward the front. The inclined surface is inclined toward the hole 81 side (outer peripheral side).

  According to the above configuration, the water adhering between the base portion 61 and the lip portion 62 of the seal member 50 can be efficiently discharged toward the drain hole 81 and discharged from the drain hole 81. For this reason, in the seventh and eighth embodiments, even if the number of drain holes 81 is smaller than in the fifth and sixth embodiments, the same effect as in the fifth and sixth embodiments can be obtained. Can do.

  In the ninth embodiment of the present invention shown in FIG. 14, a drain hole 81 is provided in the seal member 50 shown in the first embodiment. Specifically, a drain hole 81 is provided at a boundary portion between the lip portion 53 and the locking portion 52 of the seal member 50. Even in such a configuration, the same operations and effects as in the fifth and sixth embodiments can be obtained.

  The tenth embodiment of the present invention shown in FIG. 15 is different from the above-described sixth embodiment in the following points. That is, in the metal ring 63, a portion corresponding to the plurality of drain holes 81 provided at the front end portion of the base portion 61 of the seal member 60 is cut and raised instead of the hole 82 (corresponding to an engagement piece portion). Is provided. The cut and raised 91 is engaged with the hole 83 when the seal member 60 is fitted to the inner periphery of the seal holding portion 13a. According to such a configuration, it is possible to prevent the seal member 60 from moving backward in the axial direction and coming out of the seal holding portion 13a.

The present invention is not limited to the above-described embodiment, and for example, the following modifications are possible.
In any of the above-described embodiments, the washing / drying machine including the heater-type drying device 30 is shown. However, the present invention can also be applied to a washing / drying machine including a heat pump-type drying device.
The present invention can also be applied to a washing and drying machine in which a laundry input port is provided on the upper surface of the outer box 3.
