Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments thereof. FIG. 1 is a perspective view showing a washer / dryer according to an embodiment of the present invention from a diagonally upper front point of view, and FIG. 2 is a schematic side sectional view showing the washer / dryer of FIG. In the washing and drying machine shown in FIG. 2, the left side is the front surface and the right side is the back surface.
(Example of the washing and drying machine according to the first embodiment of the present invention)
The washing / drying machine 1 is a fully automatic type and includes an outer box 10 having a substantially rectangular parallelepiped shape. The outer box 10 is open at the top and bottom. The upper open portion of the outer box 10 is covered with an upper surface plate 11. An operation unit 71 for operating the washing / drying machine is provided in front of the top plate 11. A back panel 14 is mounted on the back side of the top plate 11.

  An entrance / exit 11a for feeding laundry into the washing / drying machine 1 is opened at the center of the top plate 11. The entrance / exit 11a is opened and closed by a lid 15 pivotally supported by a hinge 15a provided at the front end of the back panel 14. The outer shape of the lid portion 15 is substantially D-shaped in a plan view, and the direct portion is pivotally supported so as to be opened and closed. Packing (not shown) is provided on the periphery of the lid portion 15 so that the space between the doorway 11a and the lid portion 15 is kept airtight. By rotating the lid portion 15 up and down to open and close the entrance / exit 11a, the laundry can be put into or taken out of the dehydration tank 30 described later.

  According to the present invention, the lid portion 15 is provided with the locking portion 4 that can hang the hanger portion 3. The locking portion 4 is rotatably provided at the substantially central portion of the lower surface of the lid portion 15. Further, a hanger drive motor 5 that is a drive mechanism of the locking portion 4 is provided inside the lid portion 15. The rotation of the hanger drive motor 5 from the rotating shaft is directly connected to the forming portion 4 or connected to the locking portion 4 which can be rotated via a transmission mechanism (not shown). Therefore, the latch 4 is rotated by the hanger drive motor 5 being driven (rotated), and the hanger 3 that is suspended is rotated. When a transmission mechanism or the like is required, a hanger drive mechanism is configured including this transmission mechanism.

  For example, as shown in FIG. 7, the hanger portion 3 is provided with a hook 3 b that is suspended from the locking portion 4 on the upper surface at the center of a circular hook portion 3 a. The hook 3b can be detached from the locking portion 4. In addition, the hanger portion 3 is provided with a plurality of clips (normal laundry scissors, pinches, etc.) 3c for sandwiching and hanging laundry, clothes, etc. on the lower surface opposite to the hook 3b. The clip 3c is not a clip that sandwiches laundry or the like, but may be a hanger-shaped one that is generally known to hang a shirt or the like.

  The hanging portion 3a has a structure shown in FIG. The hanging portion 3a has a circular edge portion 3d, and has a plurality of crosspieces 3e extending radially from the center of the edge portion 3d. The end of each crosspiece 3e is coupled to the edge 3d to form a hanging portion 3a. Therefore, a gap is formed between the crosspieces 3e to improve the air flow. A clip 3c is provided on the crosspiece 3e as shown in FIG.

  The outer diameter of the hanging portion 3a is formed to be smaller than the inner diameter of the balancer 32 provided at the upper end edge of the dewatering tub 30 that also serves as a washing tub, which will be described later, and smaller than the inner diameter of the entrance / exit 11a. As a result, the hanging portion 3a is smoothly rotated, and the laundry or the like suspended from the clip 3c is also rotated without any trouble.

  The hanging portion 3a is not limited to the shape shown in FIG. 7, but may have a crosspiece structure having a lattice shape. As in the case where the crosspieces are provided radially, the air flow is not obstructed through the gap between the lattice shapes. Further, even if there is no circular edge 3d for connecting the ends of the bars 3e, the edges of the grids or the radial bars may be formed in a circle.

  FIG. 3 is a perspective view showing a part of the washing tub with the lid 15 of the washing / drying machine 1 being opened. The lid portion 15 is provided with a locking portion 4 according to the present invention as shown in the figure.

  In FIG. 1 to FIG. 3, a dewatering tank 30 that also serves as a washing tub and a water tank 20 that houses the dewatering tub 30 are provided inside the outer box 10. 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 the shape of a bottomed cylindrical cup having an open top surface, and are arranged concentrically with the water tank 20 on the outside and the dewatering tank 30 on the inside, with the axis being vertical. The

  The water tank 20 is suspended inside the outer box 10 by a suspension member 21. Suspension members 21 are provided at a total of four locations so as to connect the lower outer surface of the water tank 20 and the inner corners of the outer box 10, and support the water tank 20 so that it can swing within the outer box 10.

  The dewatering tank 30 has a peripheral wall extending upwardly in a tapered shape, and this peripheral wall has no opening for allowing liquid to pass except for a plurality of dewatering holes 31 arranged in an annular shape at the uppermost portion. 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, which is a stirring blade for stirring and flowing the washing water 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 dewatering shaft 44 penetrates the water tank 20 and is connected to the dewatering tank 30 to support the dewatering 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 support the pulsator 33. Seal members for preventing water leakage are disposed between the dewatering shaft 44 and the water tank 20 and between the dewatering shaft 44 and the pulsator shaft 45, respectively.

  The outer box 10 is provided with an extending portion 16 that extends downward from the periphery of the doorway 11a. The extending portion 16 has a substantially vertical vertical portion 16a formed in an annular shape and a horizontal portion 16b extending substantially horizontally from the lower end of the vertical portion 16a. The end of the horizontal portion is fixed to the outer box 10. An annular bellows-like elastic body 17 is attached to the lower surface of the horizontal portion 16b. The extending portion 16 and the upper surface of the water tank 20 are connected by the elastic body 17, and the vibration of the water tank 20 due to the rotation of the dewatering tank 30 or the like is absorbed.

  Further, the extending portion 16 and the elastic body 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. With the above configuration, when drying is performed, the laundry can be dried using not only the dewatering tank 30 but also the space up to the lid 15 that can be opened and closed, that is, a large space.

  A drying unit 91 constituting a drying mechanism including an air passage is installed on the extended portion 16 at the rear portion of the outer box 10. The drying unit 91 includes a blower 50 and a heater 54 in the air passage, and a water level sensor (not shown), a drive motor (not shown) for an opening / closing member 61 described later, and the like are installed on the horizontal portion 16b.

  In the drying unit 91, the first opening 51b and the exhaust port 53a are opened in the vertical part 16a of the extending part 16, and the second opening 51c and the outlet 51d are opened in the horizontal part 16b. The first opening 51 b and the second opening 51 c form a suction port 51 a of the circulation duct 51. The air outlet 51d is arranged so as to blow out hot air along the inner peripheral wall of the dewatering tank 30 downward. The drying unit 81 is configured by including an air passage including the circulation duct 51 extending from the suction port 51a to the air outlet 51d.

  The exhaust port 53a is led out to the exhaust duct 53 that is open to the atmosphere, and opens above the suction port 51a and is arranged in the vicinity of the entrance / exit 11a. An exhaust filter 56 is provided in the exhaust duct 53. The exhaust filter 56 can prevent the fibers contained in the exhaust from being scattered in the room during the drying process.

  The suction port 51 a and the air outlet 51 d are connected by a circulation duct 51, and the blower 50 and the heater 54 are arranged in the circulation duct 51. Thus, the circulation duct 51 forms a suction duct 51e between the suction port 51a and the blower 50, and forms a blowout duct 51f between the blower 50 and the blower outlet 51d.

  The blowout duct 51f extends upward from the blowout opening 51d, and then bends in a substantially horizontal direction, and the blower 50 and the heater 54 are disposed. The suction duct 51e extends downward from the blower 50, bends forward, and then branches to communicate with the first opening 51b and the second opening 51c from the suction duct 51e. Thereby, the air blower 50 and the heater 54 are arrange | positioned in the position higher than the suction inlet 51a.

  The heater 54 is composed of a PTC (Positive Temperature Coefficient) heater, and warm air is sent out from the outlet 51 d by driving the blower 50 and the heater 54. If the hot air becomes too hot, the synthetic resin parts inside the washer / dryer 1 may be melted. For this reason, it is good to set so that the blowing temperature from the circulation duct 51 may not exceed 90 ° C.

  An intake filter 55 is provided in the suction duct 51e. The intake filter 55 is supported by a frame 55a (see FIG. 3) of a resin molded product, and is disposed downstream of the second opening 51c. The front surface of the frame body 55a (not indicated in the figure) opens to form the first opening 51b, and the lower surface of the frame body 55a opens to communicate with the second opening 51c. Accordingly, it is possible to put the finger on the second opening 51c and pull out the intake filter 55 for cleaning.

  The intake filter 55 can prevent foreign matter (mainly fibers) from being sucked into the blower 50 or attached to the heater 54 and burnt. Further, since the first opening 51b and the second opening 51c that form the suction port 51a of the circulation duct 51 are provided on the front surface and the lower surface of the extending portion 16, respectively, the airflow flowing into the circulation duct 51 is increased. Can do.

  An outside air introduction duct 57 is connected to the circulation duct 51 upstream of the blower 50. The outside air introduction duct 57 communicates with the upper portion and the lower portion of the horizontal portion 16 b through the opening portion 13 provided in the horizontal portion 16 b of the extending portion 16. An outside air introduction duct 57 below the horizontal portion 16 b is formed between the water tank 20 and the outer box 10. The drying unit 91 is provided with an opening / closing member 61 that opens and closes the opening 13.

  A PCI generator 80 for generating plasma cluster ions (hereinafter referred to as “PCI”) composed of positive ions and negative ions is provided above the circulation duct 51. The PCI generated by the PCI generator 80 is discharged into the circulation duct 51. Further, a PCI external discharge duct 82 for discharging PCI to the outside of the circulation duct 51 is formed on the downstream side of the PCI generator 80.

  A PCI discharge valve 81 that discharges PCI to the outside of the machine is provided at a branch portion between the circulation duct 51 and the PCI outside discharge duct 82. The PCI discharge valve 81 opens the circulation duct 51 and closes the PCI outside discharge duct 82 (solid line state in FIG. 1), and also opens the PCI outside discharge duct 82 and partially opens the circulation duct 51 (in FIG. 1). Take one of the postures in the broken line state).

  Further, the horizontal portion 16b of the extending portion 16 is provided with a water supply port (not shown). The water supply port is connected to city water via a water supply valve 77 (see FIG. 4). Therefore, the water supply port and the water supply valve 77 constitute a water supply unit that supplies water to the dehydration tank 30.

  A drain hose 60 for draining the water in the water tank 20 and the dehydration 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 dehydration 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 dehydration tank 30 during dehydration passes through between the peripheral wall of the water tank 20 and the peripheral wall of the dehydration tank 30 and is drained from the drain hose 60.

  FIG. 4 is a block diagram showing the configuration of the washing / drying machine 1. The washing / drying machine 1 is provided with a control unit 70 that controls each unit. The control unit 70 has a control board (not shown), and is arranged on the upper back of the outer box 10. The controller 70 includes a hanger drive motor 5, a dewatering tank 30, a motor 41 for rotating the pulsator 33, a clutch / brake mechanism 43, a blower 50, a heater 54, an opening / closing member 61, a water supply valve 77, a PCI generator 80, a PCI. A discharge valve 81, an operation unit 71, a display unit 72, a lid opening / closing sensor 73, a water level sensor 74, a temperature sensor 75, and a humidity sensor 76 are connected.

  The display unit 72 is provided in the operation unit 71 and displays an operation screen and an operation state of the washing / drying machine 1. The lid opening / closing sensor 73 detects the opening / closing state of the lid portion 15. The water level sensor 74 detects the water level in the dehydration tank 30. The temperature sensor 75 detects the temperature inside the dehydration tank 30. The humidity sensor 76 detects the humidity inside the dehydration tank 30.

  In the washing / drying machine 1 having the above-described configuration, the laundry is put into the dewatering tank 30 from the entrance / exit 11a, and the lid 15 is closed. At this time, the hanger portion 3 shown in FIG. 2 is removed from the locking portion 4. When a washing condition is selected by the operation unit 71 and the start of washing is instructed, the lid opening / closing sensor 73 detects that the lid unit 15 is closed, and the washing process and the drying process are executed.

  In the washing process, the drain valve 63 is closed and the water supply valve 77 is opened to supply water 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 77 is closed by detection of the water level sensor 74. Next, the pulsator shaft 45 is connected to the motor 41 by the clutch / brake mechanism 43 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 operation, 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. Water splashed from the laundry due to 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 elapses after starting the dehydrating operation, the motor 41 is stopped, the drain valve 63 is closed, and the water supply valve 77 is opened. When a predetermined amount of water accumulates in the dewatering tank 30, the water supply valve 77 is closed by detection of the water level sensor 74. Next, the pulsator shaft 45 is connected to the motor 41 by the clutch / brake mechanism 43 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 the washing process, the outside air introduction duct 57 is opened by the opening / closing member 61 as shown in FIG. For this reason, when the water level rises to above the water tank 20 due to a failure of the water supply section and water flows into the circulation duct 51, the open / close member 61 is opened and the water is discharged through the outside air introduction duct 57. This prevents the blower 50, the heater 54, and other electrical components disposed in the drying unit 91 from being flooded.

  Next, a drying process is performed. The drying process is provided with an inside air circulation period and an outside air introduction period. As shown in FIG. 5, the open / close member 61 is closed and the blower 50 and the heater 54 are driven during the inside air circulation period. Thereby, the air in the water tank 20 circulates through the circulation duct 51. During the outside air introduction period, as shown in FIG. 6, the opening / closing member 61 is opened to drive the blower 50 and the heater 54. Thereby, the outside air flowing in from the outside air introduction duct 57 is heated and sent into the water tank 20, and is exhausted from the exhaust duct 53.

  When the drying process is started, the air in the water tank 20 flows into the circulation duct 51 through the suction port 51a during the inside air circulation period by driving the blower 50. The air flowing into the circulation duct 51 is heated by the heater 54 and sent out into the water tank 20 from the outlet 51d. Thereby, the air in the water tank 20 is heated.

  Since warm air does not go out of the washing / drying machine 1 during the inside air circulation period, heat is confined in the water tank 20. Moreover, since the dehydration tank 30 is a holeless type, the amount of air leaking out from the dehydration tank 30 is small, and air hardly convects in the space between the dehydration tank 30 and the water tank 20. For this reason, the space in which the air circulates and circulates is almost limited to the inside of the dehydration tank 30, the convection and the circulation proceed efficiently, and the temperature in the dehydration tank 30 rises quickly.

  At this time, since the evaporation of water from the laundry becomes active at 50 ° C. or higher, the inside of the dewatering tank 30 is raised to 50 ° C. or higher during the inside air circulation period. At this time, the dewatering tank 30 is rotated at a lower rotational speed than the rotational speed at the time of dehydration so that the warm air is uniformly applied to the laundry inside the dehydrating tank 30. Since the pressure in the water tank 20 increases due to the temperature rise, a part of the air is exhausted to the outside through the exhaust duct 53.

  When the temperature inside the dewatering tank 30 rises, the water evaporates from the laundry, and the air in the inside air circulation in the water tank 20 contains a lot of water. When the temperature sensor 75 detects that the internal temperature of the dehydration tank 30 has risen to a predetermined value, the outside air introduction period is switched. When the humidity sensor 76 detects that the internal humidity of the dehydration tank 30 has risen to a predetermined value, it may be switched to the outside air introduction period.

  In the outside air introduction period, the opening / closing member 61 is opened as shown in FIG. As a result, the air is introduced into the circulation duct 51 from both the suction port 51 a and the outside air introduction duct 57 to the blower 50. Then, the air heated by the heater 54 flows through the blowout duct 51f and is sent downward from the blowout port 51d. Since the outside air is heated from the outside air introduction duct 57 and supplied into the water tank 20, the air containing a large amount of water in the water tank 20 is exhausted to the outside through the exhaust duct 53. Thereby, moisture is efficiently discharged from the water tank 20.

  At this time, warm air is sent out along the peripheral surface of the dehydration tank 30 downward from the outlet 51d, flows through the dehydration tank 30, and flows out from the front to the top of the dehydration tank 30. The air that has flowed out above the dehydration tank 30 flows rearward along the lid 15, and flows out from the exhaust port 53 a disposed in the vicinity of the lid 15. Thereby, an airflow can distribute | circulate smoothly through the sealed space enclosed by the water tank 20 and the shielding part (extension part 16, elastic body 17), and it can dry laundry efficiently.

  On the other hand, not all the air in the dehydration tank 30 is exhausted from the exhaust duct 53, but a part of the air circulates in the circulation duct 51 through the suction port 51a. Thereby, the high-temperature state inside the dehydration tank 30 can be maintained and the water evaporation rate from the laundry can be kept high.

  When the outside air introduction period is continued and the humidity detected by the humidity sensor 76 is lower than a predetermined value, the blower 50, the heater 54, and the motor 41 are stopped. Then, the completion of the washing process and the drying process is notified by display on the display unit 72, voice, or the like.

  When the laundry is set to be sterilized by PCI in the drying process, the PCI external discharge valve 81 closes the PCI external discharge duct 82 and the PCI generator 80 is driven. Thereby, PCI is discharged | emitted in the circulation duct 51, and the air containing PCI in the dehydration tank 30 is sent out from the blower outlet 51d.

  The PCI adheres to the laundry and can perform sterilization, fungicide, deodorization, etc. of the laundry. In addition, the dehydration tank 30, the circulation duct 51, the intake filter 55, the blower 50 can be sterilized, mildew-proof, deodorized, and the like, and these can be maintained in a good sanitary state.

  If the setting is such that indoor sterilization or the like is performed by PCI in the drying process, the PCI generator 80 is driven by opening the PCI external discharge duct 82 by the PCI discharge valve 81. As a result, most of the PCI is discharged from the PCI external discharge duct 82 to the outside of the apparatus. The PCI discharged from the PCI outside discharge duct 82 diffuses into the room where the washing / drying machine 1 is placed, and can perform sterilization, mold prevention, deodorization and the like in the room.

  When the power of the washing / drying machine 1 is stopped, the opening / closing member 61 is closed. Thereby, intrusion of dust into the circulation duct 51 can be prevented.

  Note that the suction duct 51e may be closed during the outside air introduction period. Alternatively, the outside air introduction period may be performed for a predetermined period with the suction duct 51e opened and then for a predetermined period with the suction duct 51e closed.

  Further, the dehydration tank 30 may be temporarily rotated at a high speed during the outside air introduction period. Thereby, the wind speed of the convection inside the dehydrating tank 30 is increased, and evaporation of moisture from the laundry and discharge of the evaporated moisture can be promoted.

  According to the present embodiment, the opening / closing member 61 is closed during the inside air circulation period of the drying process, and the air in the water tank 20 can be circulated through the circulation duct 51 to quickly raise the temperature, and the opening / closing member 61 is opened during the outside air introduction period. Since the heated outside air is supplied into the water tank 20 through the outside air introduction duct 57 and exhausted through the exhaust duct 53, the water evaporated from the laundry can be discharged and the laundry can be dried. Therefore, there is no need to provide a dehumidifying means for dehumidifying air containing moisture as in the conventional example, and the manufacturing cost and running cost of the washing / drying machine 1 can be reduced.

  Moreover, since the space | interval of the entrance / exit 11a and the upper surface of the water tank 20 are covered with the extension part 16 and the elastic body 17 (shielding part), it is not necessary to provide an inner cover in the upper surface of the water tank 20, and can reduce a number of parts. At this time, since the opening / closing member 61 is opened in the washing process, when the water level rises above the water tank 20 due to a failure of the water supply section and the water flows into the circulation duct 51, the water is drained through the outside air introduction duct 57. Accordingly, it is possible to prevent the electrical components such as the blower 50 and the heater 54 from being flooded.

  In addition, since the blower 50 and the heater 54 are disposed above the suction port 51a, the flooding of the blower 50 and the heater 54 can be more reliably prevented.

  Moreover, it has the extension part 16 extended below from the circumference | surroundings of the entrance / exit 11a, and the elastic body 17 which connects between the extension part 16 and the upper surface of the water tank 20, and has the blower outlet 51d, the suction inlet 51a, and the exhaust port 53a. Since the elastic body 17 absorbs the vibration of the water tank 20 due to the rotation of the dehydrating tank 30 or the like, a shielding part that shields between the entrance / exit 11a and the water tank 20 can be easily realized. .

  Moreover, since the opening / closing member 61 is closed when the power is stopped, it is possible to prevent dust from entering the circulation duct 51.

  In the washing / drying machine 1 having the above-described configuration, the present invention applies the drying described in the drying process described above in detail by hanging the laundry, clothes, etc. on the clip 3c of the hanger part 3 or the hanger as shown in FIG. It can be dried by controlling the operation.

  At this time, the hanger part 3 is rotated via the locking part 4 by driving the hanger drive motor 5 provided on the lid part 15. By this rotation, drying is performed in a state where the drying operation of the laundry or clothes is improved. That is, unlike the drying of the laundry staying at the bottom of the dewatering tank 30, the drying operation is executed while being hung on the hanger 3. Therefore, the warm air is sufficiently convected through the laundry or the like, and is circulated well. Moreover, since laundry, clothes, etc. are dried in a state of being hung on a hanger or the like, the generation of wrinkles and the like is suppressed and reduced as much as possible.

  Moreover, in the washing / drying machine 1 of the present invention, if the PCI generator 80 is driven together with the drying operation, the generated PCI spreads over and fills the entire area of the lower part of the lid 15 including the inside of the washing tub 30. Deodorization, sterilization, and sterilization of clothing and laundry can be performed efficiently.

  Furthermore, since the hanger part 3 is rotated, the drying efficiency can be increased, and at the same time, the efficiency of character deodorization, sterilization, sterilization, etc. can be increased.

  According to the washing / drying machine 1 of the present invention, since the hanger part 3 does not have to be stored in the washing tub 30, it can be dried even in bulky laundry, clothes and the like. For example, it can be prevented from being caught by a pulsator (stirring blade) 33 located at the bottom of the washing tub 30, such as a shirt or trousers having a long base. Accordingly, there is no limit to small laundry items.

  Next, another usage pattern of the washing / drying machine 1 according to the present invention will be described. In the above description, drying of laundry, other clothes, etc. has been described. However, it can be used for the purpose of sterilization, sterilization, deodorization and the like without aiming only at drying. That is, clothes, stuffed animals, shoes, and the like that are already dry are hung on the hanger portion 3 according to the present invention. As shown in FIG. 2, the hook portion 3 c of the hanger portion 3 is hooked (locked) on the locking portion 4 of the lid portion 15, and the PCI generator 80 and the blower 50 are driven. At this time, the heater 54 which is a heating member is set in a driven state.

  Through the above operations, clothes and the like can be sterilized, sterilized, deodorized, and the like. Moreover, since it is the state hung on the hanger part 3, wrinkles etc. do not arise. In addition, deodorization, sterilization, and sterilization of shoes that cannot be washed can be realized.

  The hanger part 3 of the present invention is configured such that the outer diameter of the hanging part 3a is smaller than the inner diameter of the balancer 32 provided in the upper part of the washing tub 30 and the inner diameter of the doorway 11a (particularly the inner diameter of the lead hanging part 16a). Yes. Therefore, the hanger part 3 can be rotated without trouble in the upper part of the washing tub 30. Further, it is possible to prevent the laundry and the like from being caught around the laundry tub 20 and other parts such as the balancer 32 as much as possible.

(Second embodiment of the present invention)
According to the first embodiment described above, as the structure for rotating the hanger portion 3, the locking portion 4, the hanger drive motor 5, and the like are provided on the lid portion 15.

  Separately from this, an implementation example that can be rotated by the existing components of the washing / drying machine 1 will be described below.

  For example, in order to prevent small items such as laundry from contacting and catching with the dehydrating tub 30, the hanger portion 3 can be stored in the washing tub 30, and the rotation of the washing tub 30 is used. You may make it perform drying etc. However, in the structure of the hanger part 3 described above, the hanger part 3 cannot be rotated using the rotation of the washing tub 30.

  In order to realize this, as shown in FIG. 8, a ring-shaped engagement portion 9 that is a friction member such as rubber is provided on the outer peripheral edge of the hanging portion 3 a (edge portion 3 d) of the hanger portion 3. The engaging portion 9 is formed with a recess 9a around the entire periphery of the engaging portion 9 in which the outer edge of the hanging portion 3a (edge portion 3d) is fitted. Therefore, by using the elastic deformation of the hook portion 3 a and the engaging portion 9, the hook portion 3 a (edge portion 3 d) is fitted into the concave portion 9 a of the engaging portion 9.

  The laundry or the like is suspended from the hanger portion 3 in which the engaging portion 9 is fitted, the lid portion 15 of the washing / drying machine 1 is opened, and the hanger portion 3 is placed on the balancer 32 of the dewatering tank 30 as shown in FIG. Put. The balancer 32 is formed so that the upper part thereof is tapered and narrows downward so that the engaging part 3e of the hanger part 3 can be easily placed. Therefore, the hanger part 3 is easily placed on the balancer 32. At this time, the engaging portion 9 made of rubber or the like serves as a weight, and the hanger portion 3 is reliably placed on the balancer 32, and the rotation of the dehydrating tank 30 is reliably transmitted and rotated without slipping.

  In this state, as described above, the drying operation, and the operation for sterilization and deodorization by PCI can be performed. In addition, the hanger part 3 is rotated by rotating the dehydration tank 30. In this case, the engaging portion 9 that comes into contact with the balancer 32 is made of a friction member, so that a good contact is made and it plays the role of a weight, and the hanger portion 3 is rotated in accordance with the rotation of the dewatering tank 30. . As a rotation speed of the dehydration tank 30, it is preferable to rotate at a slow speed that does not cause the hanger portion 3 to shift. For example, it is driven to make one rotation in 5 to 10 seconds. Thereby, the laundry can be rotated without falling from the hanger portion 3.

  According to the configuration of the engaging portion 9 described above, the state of being placed on the balancer 32 so as to play the role of a weight has been described. Therefore, the example which provided the taper part in the balancer 32 was shown. Instead of such a configuration, another mode in which the engaging portion 9 is engaged with the balancer will be described.

  For example, at least the lower periphery of the engaging portion 9 is provided with a plurality of concavities and convexities that are engaged with the uneven portions formed on the balancer 32 and a plurality of protrusions that are engaged with the concave portions, that is, claws. With such a configuration, by placing the engaging portion 9 on the balancer 32, a protrusion or a claw is locked to the uneven portion formed on the balancer 32. Thereby, the hanger part 3 will rotate because the spin-drying | dehydration tank 30 rotates.

(Third embodiment of the present invention)
According to said 2nd Embodiment, the structure which rotates the hanger part 3 using rotation of the dehydration tank 30 was demonstrated. Therefore, the hanger part 3 can be rotated with the existing structural member with which the washing / drying machine 1 is equipped, without using the rotation mechanism (hanger drive mechanism) provided in the cover part 15, ie, the hanger drive motor 5 and the latching part 4. it can.

  Another configuration example in which the hanger portion 3 can be rotated with existing components will be described below. As the rotating member, in addition to the dehydrating tank 30, the pulsator 33 exists as described above. The hanger unit 3 is rotated using the rotation of the pulsator 33.

  The hanger portion 3 according to this embodiment cannot be rotated with the structure shown in FIG. Therefore, as shown in FIG. 10, the support rod 6 is attached to the center O of the hanging portion 3a (the center of the beam 3e provided radially in FIG. 7) so as to be screwed. The opposite side of the support bar 6 is fixed by penetrating a support plate 7 having the same shape as the hanging portion 3a shown in FIG. Moreover, the lower part of the support bar 6 is provided so that it may fit in the recessed part 33b (refer FIG. 11) corresponding to the rotation center axis | shaft of the pulsator 33. FIG.

  A plurality of pins 8 are provided on the lower surface of the support plate 7 in order to support the hanger portion 3 in a stable state. The pin 8 is formed in such a size that it can be inserted into a hole 33c provided in a stirring blade (stirring fin) 33a on which the pulsator 33 is projected. That is, although the description will be mixed, the pulsator 33 is fixed to the agitating blade 33a projecting upward in a cross shape to agitate the water in the dehydrating tank 30, and to the pulsator shaft 45 described above. A recess 33b for screwing is provided. Furthermore, a large number of suction holes 33c for sucking the water in the dewatering tank 30 into the gap between the pulsator 33 and the dewatering tank and a blowout hole 33d for providing a large number of sucked water on the outer peripheral surface of the pulsator 33 are formed. . Thereby, the convection of water is favorably performed by the rotation of the pulsator 33, and the efficiency at the time of washing and rinsing can be improved. Therefore, a plurality of rotary fins for forming a pump are formed on the back side of the pulsator 33.

  The pin 8 provided on the support plate 7 described above is provided so as to be inserted into the suction hole 33 c provided in the stirring blade 33 a of the pulsator 33. For this purpose, a guide plate may be provided that facilitates insertion of the pin 8 and at the same time sandwiches the stirring blade 33a on the lower surface of the support plate 7 for positioning. The guide plate may be formed so as to sandwich at least one stirring blade 33a.

  As shown in FIG. 2, the support member including the support rod 6, the support plate 7, and the pin 8 is attached to the hanger portion 3 and the laundry or the like is hung on the hanging portion 3a. Lower. And the hanger part 3 is hold | maintained on the pulsator 33 in the spin-drying | dehydration tank 30 by inserting the lower part of the support rod 6 in the recessed part 33b of the pulsator 33, and the pin 8 in the suction hole 33c of the stirring blade 33a.

  In this state, the lid 15 is closed and the drying operation is performed, so that the drying operation is performed as in the above-described embodiment. At the same time, by rotating the pulsator 33, the hanger part 3 is rotated, and drying is promoted together with air convection. Further, by rotating the pulsator 33, an air flow, that is, convection is generated as in the case of convection of water, and drying is further promoted. That is, the air sucked from the suction hole 33c of the pulsator 33 is blown out through the blowout holes 33d provided around the pulsator 33, and air convection is performed well. Therefore, drying efficiency is promoted.

  The hanger portion 3 according to this embodiment has the support rod 6 attached, and the lower portion thereof is fitted into the recess 33 b of the pulsator 33, so that the center of rotation is secured and simultaneously held on the pulsator 33. As shown in FIG. 11, when a female screw is formed in the concave portion 33b of the rotation center portion, the pulsator 33 can form a male screw at the end of the support bar 6 in accordance with the female screw. Thereby, the hanger part 3 can be fixedly held on the pulsator 33 by mutual screwing. Therefore, the hanger part 3 can be held on the pulsator 33 without providing the support plate 7 or the pins 8.

  As described above, regarding the rotation of the pulsator 33, when the drying operation is executed in the first embodiment, that is, in the state shown in FIG. 2, the drying efficiency is improved by rotating the pulsator 33 together with the rotation of the hanger drive motor 5. Will be promoted. Moreover, further effects can be expected by reversing these rotations.

  That is, according to the third embodiment, the rotation directions of the hanger part 3 and the pulsator 33 are the same. However, by utilizing a part of the configuration of the first embodiment, it is possible to reverse the rotation of the hanger portion 3 and the rotation direction of the pulsator 33. This can be realized because the rotation driving unit is individual.

  It should be noted that the effects of sterilization and deodorization are naturally promoted by performing the sterilization and deodorization operation by using PCI alone or in combination separately from the drying operation. This is not limited to the third embodiment, and the same applies to the first and second embodiments.

  The present invention can be widely used in washing and drying machines.
