Note that a claw 15c is provided on the front side of the lid portion 15 so that the lid portion 15 can be hooked (latched) by being hooked on the front side upper portion of the top plate 11 when fully closed. In a state where the claw 15c is hooked on the upper surface plate 11, the lid portion 15 does not open even when an upward force is applied.

  As shown in FIG. 2, the lid portion 15 is rotatable in the vertical direction (which can also be viewed as the front-rear direction) around the axis of the hinge portion 15 a. In the following description, the position of the lid 15 in the rotational direction is an angle with the horizontal plane as a reference (0 °) (the opening direction is positive, and may be referred to as “the angle of the lid 15” below). Represent. As shown in FIG. 2, the lid 15 is rotatable within a range from a position slightly smaller than 0 ° (fully closed position) to a position slightly smaller than 90 ° (fully opened position).

  In addition, as long as the fully open position is approximately 90 °, the position may be slightly larger or slightly smaller than 90 °, 90 °, for example, 70 to 90 °, 80 to 90 °, 90 to 100 °, 90 to 90 °. 110 °, 80-100 °, 70-110 °, and the like.

  Accordingly, the user can open the lid portion 15 by rotating the lid portion 15 upward, and close the lid portion 15 by rotating the lid portion 15 downward. In a state in which the lid portion 15 is opened (in other words, in a state in which the entrance / exit 11a is opened), the user inputs laundry into the dehydration tank 30 or takes out laundry from the dehydration tank 30. can do.

  Further, a hook 18 for hanging the hanger 2 is provided on the surface (inner surface) of the lid portion 15 facing the entrance / exit 11a. Details of the hook 18 and the hanger 2 will be described later. Accordingly, as shown in FIGS. 4 and 6, the user can hang the hanger 2 to which the clothing (the object to be dried) is attached on the hook 18 with the lid 15 opened. Therefore, workability at the time of hanging and drying is good. In FIGS. 4 and 6, the display of clothing is omitted.

  From this state, the lid 15 is closed by the user (in other words, the doorway 11a is closed), so that the clothes can be suspended in the dehydrating tank 30. As will be described later, the washing / drying machine 1 can perform hanging drying on clothes hung using the hanger 2.

  Inside the outer box 10, a dewatering tank 30 that also serves as a washing tub and a water tank 20 that houses the dewatering tub 30 are housed. The dewatering tank 30 stores water in which detergent is dissolved or water for rinsing (hereinafter collectively referred to as “washing water”). Both the water tank 20 and the dewatering tank 30 have a shape of a bottomed cylindrical cup that opens upward, and are concentrically with the water tank 20 on the outside and the dewatering tank 30 on the inside, with the axes being vertical. Placed in.

  The water tank 20 is suspended by the suspension member 21. The suspension member 21 is provided at a total of four locations in such a manner that the lower outer surface of the water tank 20 and the inner corner of the outer box 10 are connected, and supports the water tank 20 so that it can swing within a horizontal plane.

  The dewatering tank 30 has a peripheral wall extending upwardly in a tapered shape, and there is no opening for allowing liquid to pass through the peripheral wall except for a plurality of dewatering holes 31 arranged in an annular shape at the top. That is, the dewatering tank 30 is formed in a so-called “no hole” type. An annular balancer 32 is attached to the edge of the upper opening of the dewatering tub 30 to suppress vibration when the dewatering tub 30 is rotated at a high speed for dewatering the laundry. A pulsator 33 for causing the washing water to flow in the tank is disposed on the inner bottom surface of the dewatering tank 30.

  A drive unit 40 is attached to the lower surface of the water tank 20. The drive unit 40 includes a motor 41 and a clutch / brake mechanism 43. The clutch / brake mechanism 43 is connected to the motor 41 by a belt 42, and the dewatering shaft 44 and the pulsator shaft 45 protrude upward. The clutch / brake mechanism 43 operates by electromagnetic force, and alternatively connects one of the dewatering shaft 44 and the pulsator shaft 45 to the motor 41. The clutch / brake mechanism 43 brakes the rotation of the dehydrating shaft 44 by electromagnetic force and releases the brake.

  The dewatering shaft 44 and the pulsator shaft 45 have a double shaft structure. The dewatering shaft 44 is disposed outside and the pulsator shaft 45 is disposed inside. The dehydrating shaft 44 penetrates the water tank 20 and is connected to the dehydrating tank 30 and pivotally supports the dehydrating tank 30. The pulsator shaft 45 passes through the water tank 20 and the dewatering tank 30 and is connected to the pulsator 33 to pivotally support the pulsator 33. Seal members for preventing water leakage are disposed between the dehydrating shaft 44 and the water tank 20 and between the dewatering shaft 44 and the pulsator shaft 45, respectively.

  On the lower side of the upper surface plate 11, a substantially cylindrical connecting component 17 having a side surface with a bellows shape is fixed. The top plate 11 and the water tank cover 20a are connected by the connecting component 17 so that the vibration of the water tank 20 due to the rotation of the dewatering tank 30 is absorbed.

  Further, the upper surface plate 11 and the connecting component 17 constitute a shielding portion that shields between the periphery of the entrance / exit 11 a and the upper surface of the water tank 20. A sealed space is formed between the water tank 20 and the entrance / exit 11a by the shielding portion. Thereby, the inner cover which opens and closes the upper surface of the water tank 20 is not required, and the lid 15 can be closed to perform washing and drying.

  A drying unit is installed on the upper surface plate 11 at the rear of the outer box 10. The drying unit includes a blower, a heater, and the like, and has a function of blowing warm air along the inner peripheral wall of the dewatering tank 30 (supplying warm air into the dewatering layer 30) when the hanging drying operation is performed. ing.

  Further, a water supply port is provided in the rear portion of the top plate 11. The water supply port is connected to city water through a water supply valve. Thus, the water supply port and the water supply valve constitute a water supply unit that supplies water to the dehydration tank 30. The water supply port is designed so that foreign matters such as dust do not enter inside.

  A drain hose 60 for draining water in the water tank 20 and the dewatering tank 30 to the outside of the outer box 10 is attached to the bottom of the water tank 20. The dewatering tank 30 is provided with four drain holes 62 on the same circumference, and each drain hole 62 and the drain hose 60 are connected by a drain duct 61. A drain valve 63 is provided in the drain duct 61. When the drain valve 63 is opened, the water in the dewatering tank 30 is drained through the drain duct 61 and the drain hose 60. Further, the water that flows out from the upper part of the dewatering tank 30 during dehydration passes between the peripheral wall of the water tank 20 and the peripheral wall of the dewatering tank 30 and is drained from the drain hose 60.

  The washing / drying machine 1 also includes a lid opening / closing sensor that detects the open / closed state of the lid 15, a water level sensor that detects the water level of the dehydration tank 30, a temperature sensor that detects the temperature inside the dehydration tank 30, and the interior of the dehydration tank 30. Various sensors such as a humidity sensor for detecting the humidity of the water are provided.

  In addition, the washing / drying machine 1 includes a control device that controls each unit so that the washing / drying machine 1 operates appropriately in accordance with user operations, detection information of various sensors, and the like. The said control apparatus is distribute | arranged to the back upper part of the outer case 10, for example, and controls the motor 41, a drying unit, etc.

  In the washing / drying machine 1 having the above-described configuration, the laundry is put into the dehydrating tank 30 from the entrance / exit 11a, and the lid portion 15 is closed. When the washing condition is selected by the user and the start of washing is instructed, the lid opening / closing sensor detects that the lid portion 15 is closed, and the operation of the washing process is executed.

  In the washing process, the drain valve 63 is closed, the water supply valve is opened, and water is supplied to the dehydration tank 30 from the water supply port. When a predetermined amount of water accumulates in the dewatering tank 30, the water supply valve is closed by detection of the water level sensor. Next, the clutch / brake mechanism 43 connects the pulsator shaft 45 to the motor 41 to drive the motor 41. Thereby, the pulsator 33 rotates and the washing operation is performed by stirring the water in the dewatering tank 30.

  When a predetermined time has elapsed since the start of the washing process, the drain valve 63 is opened to drain the water in the dewatering tank 30, and the dewatering shaft 44 is connected to the motor 41 by the clutch / brake mechanism 43. Thereby, the dehydrating tank 30 is rotated at a high speed by the drive of the motor 41 and the dehydrating operation is performed. The water splashed from the laundry by the high-speed rotation of the dewatering tank 30 flows out from the drainage duct 61 and the dewatering hole 31.

  When a predetermined time has elapsed after starting the dehydrating operation, the motor 41 is stopped, the drain valve 63 is closed, and the water supply valve is opened. When a predetermined amount of water accumulates in the dewatering tank 30, the water supply valve is closed by detection of the water level sensor. Next, the clutch / brake mechanism 43 connects the pulsator shaft 45 to the motor 41 to drive the motor 41. As a result, the pulsator 33 rotates, and the rinsing operation is performed by stirring the water in the dewatering tank 30.

  When a predetermined time has elapsed after starting the rinsing operation, the above dehydration operation is performed again. When the dehydrating operation is performed for a predetermined time, the washing process ends. In addition, the washing and drying machine 1 starts the hanging and drying operation when an instruction to perform the hanging and drying operation is given by the user.

  The hanging and drying operation is an operation of drying the suspended clothes (suspending and drying) by supplying warm air into the dehydrating tank 30 and circulating it. That is, the washing / drying machine 1 implements hanging / drying of the clothing by performing the hanging / drying operation in a state where the clothing is suspended in advance.

[Configuration of hooks and hangers]
The hook 18 of the present embodiment includes an arcuate curved portion 18a that extends in the front-rear direction and protrudes toward the dehydrating tank 30 , and a flat side wall portion 18b that extends from the left and right sides of the curved portion 18a to the lid portion 15 respectively. 18 b and two through holes 18 c and 18 d penetrating the both side wall portions 18 b and 18 b in the horizontal direction, and fixed to the lid portion 15 with screws or the like.

  And the shape of two through-holes 18c and 18d differs, and the thickness of the circumference (part used as the frame of a through-hole) of through-holes 18c and 18d also differs. That is, the front through-hole 18c has a substantially rectangular cross-sectional shape, and the lower side is obliquely raised rearward in the state of FIG. On the other hand, the rear through-hole 18d has a substantially rectangular cross-sectional shape, and its lower side is horizontal in the state of FIG. Further, in the state shown in FIG. 3, the part that becomes the frame of the through holes 18 c and 18 d is thick in the lower part of the frame of the front through hole 18 c (the lower part of the front through hole 18 c), and the frame of the rear through hole 18 d. The lower part (the lower part of the rear through-hole 18d) is thinned.

  As shown in FIG. 6, the hanger 2 has a substantially U-shaped portion, and the substantially U-shaped portion is hung on the through holes 18 c and 18 d of the hook 18.

  Thus, in the state where the lid portion 15 is opened (the state shown in FIG. 4), the upper portion of the substantially U-shaped portion of the hanger 2 is engaged with the through holes 18c and 18d, and the lower portion is engaged with the curved portion 18a. The hangers 2 and 2 hung on the hook 18 are supported obliquely with respect to the vertical direction. More specifically, in the state of FIG. 4, the hanger 2 hung on the front through hole 18c is supported more horizontally, and the hanger 2 hung on the rear through hole 18d is supported closer to the vertical direction. The This is because the lower part of the frame of the front through hole 18c is thick and the lower part of the frame of the rear through hole 18d is thin.

  Thus, since the two hangers 2 and 2 are supported at different angles with the lid 15 opened, the clothes hung on the hangers 2 and 2 are not easily overlapped, and the clothes can be easily attached and detached. Further, since the hanger 2 hung on the rear through hole 18d is supported obliquely, the clothes do not touch the detergent inlet of the top plate 11 and become dirty.

  On the other hand, when the lid portion 15 is closed (the state shown in FIG. 3), the upper portions of the substantially U-shaped portions of the hangers 2 and 2 engage with the through holes 18c and 18d, respectively, and the lower portion is separated from the curved portion 18a. The hangers 2 and 2 hung on the hook 18 are directed downward (the direction in which clothes are naturally suspended) by the action of gravity. Thus, since the hanger 2 can be attached to and detached from the hook 18, the clothes can be hung on the hanger first and then hung on the hook 18, which is highly convenient.

  In addition, with the lid portion 15 closed, the two through holes 18c and 18d are equally disposed from the center of the water tank 20 to the front and the rear in plan view. At that time, the two through holes 18c and 18d are arranged as close to the center of the water tank 20 as possible so that the clothes do not come into contact with each other.

  A hook 18 is provided in a recess inside the lid portion 15. Thus, by providing the hook 18 in the concave portion, the position of the hook 18 at the time of hanging and drying becomes high, and it becomes difficult to support a long laundry on the bottom of the tub. Furthermore, since the hook 18 is substantially accommodated in the recess, the hook 18 does not interfere with the loading and unloading of the laundry with the lid 15 opened.

  In addition, since the lid 15 in the closed state rises rearward from the front end, the position of the hanger 2 at the time of hanging and drying becomes higher by providing the through hole 18d as close to the rear of the lid 15 as possible. This makes it difficult to support the bottom of the tub even with long laundry.

  In addition, if the lower end of the hook 18 is positioned above the upper end of the water tub 20, it can be said that the position of the hook 18 at the time of hanging and drying is high and it is difficult to support the bottom of the tub even with long laundry. Therefore, if the hook 18 is provided inside the lid portion 15 as in this embodiment, it can be said that the hook 18 is provided at a sufficiently high position.

  The number of through-holes is not limited and may be at least one. However, as in the present embodiment, the number of through-holes is measured one by one from the center of the water tank 20 to the front and the rear with the lid 15 closed. If two are provided, it is difficult for the clothes to touch the inside of the tank, and a sufficient drying space can be secured.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to this content. The embodiments of the present invention can be variously modified without departing from the gist of the present invention.
