The nanoecourse will be described in detail with reference to FIGS.

  A top plate 62 that covers the housing 43 is disposed on the upper surface of the housing 43, and a control device 63 having control means (not shown) configured by a microcomputer or the like is disposed inside the top plate 62. Has been. When the start of operation is set by the input setting means 77 in the operation panel unit 60, the control means inputs data from a water level detection means (not shown) for detecting the water level in the water tank 44, etc. The operation of the drain valve 57, the water supply valve 58, etc. is controlled, and each process such as washing, rinsing, dehydration, and drying processes is controlled.

  In order to dry the clothes, the air in the water tank 44 and the rotating drum 41 is circulated by the blower unit 64. However, the air that has been deprived of moisture from the laundry in the rotating drum 41 becomes humid. The water is discharged to the heat pump unit 66 through the filter port 76 outside the rotating drum 41 through the discharge port 65 provided at the upper side of the water tank 44. The filter unit 76 prevents foreign matter from entering the heat pump unit 66 by collecting foreign matter such as lint, dust, and pollen mixed in the air passing through the rotary drum 41. In addition, the lid 80 (see FIG. 2) pivotally supported on the top plate 62 side of the upper portion of the housing 41 can be manually opened to remove foreign matter accumulated in the filter unit 76. The open / closed state of the lid 80 can be detected by a lid open / close detection means 83 (see FIG. 2) provided near the lid 80.

  The heat pump unit 66 includes a compressor 67 that compresses the refrigerant, a heating unit (heat radiator) 68 that radiates heat of the refrigerant that has been compressed to high temperature and high pressure, and a throttle unit 69 that reduces the pressure of the high-pressure refrigerant. And a dehumidifying part (heat absorber) 70 that draws heat from the surroundings by the reduced pressure and low pressure refrigerant, and a pipeline 71 that circulates the refrigerant by connecting these four members and discharged. The drying air is dehumidified by a dehumidifying section (heat absorber) 70. The drying air dehumidified by the dehumidifying part (heat absorber) 70 is heated by the heating part (heat radiator) 68. The heated drying air passes through the circulation air passage 72 from the air blowing portion 64 disposed in the middle of the circulation air passage 72 and is opened at the end of the circulation air passage 72 to the back side of the water tank 44. From 73, it blows again into the rotary drum 41, passes through the clothing, is led to the discharge port 65 again, and circulates.

  The blower unit 64 is provided downstream of the heat pump unit 66 and sends the drying air heated by the heating unit 68 to the downstream side of the circulation air passage 72. The blower unit 64 is connected to the blower fan 74 and the blower fan. And a fan motor 75.

The electrostatic atomization generating unit 81 communicates with the circulation air path 72 at the discharge port 82, and the charged fine particle water is generated from the discharge port 82 when the circulation air is flowing through the circulation air path 72. The charged fine particle water sucked into the circulating air passage 72 is discharged into the water tank 44 and the rotating drum 41 from the outlet 73 along the flow of the circulating air, and the inside of the fiber of the clothes being stirred. It penetrates deeply into the body and is sterilized and deodorized.

  The operation and action of the washing / drying machine configured as described above will be described below.

  The nano e-course for sterilization and deodorization is divided into two courses by opening and closing the lid 80, and FIG. 3 shows the first one for sterilization and deodorization inside the washing and drying machine tank according to the embodiment of the present invention. 4 is a sequence of a nano e-course (first electrostatic atomization occurrence course), and FIG. 4 shows a second nano e-course (second electrostatic atomization occurrence course) for sterilization and deodorization outside the washing dryer. ) Sequence.

  In FIG. 3, when nanoecourse is selected by the input setting means 77 of the operation panel 60 and the operation is started in a state where there is no clothing or the like in the rotary drum 41, first, the lid opening / closing that detects opening / closing of the lid 80 When the detection means 83 detects the closed state of the lid 80, the blower fan motor 75 and the electrostatic atomization generation unit 81 are operated, and the charged fine particle water generated from the electrostatic atomization generation unit 81 is circulated through the circulation air path 72. The sterilization and deodorization in the tank are started while being fed into the water tank 44 and the rotating drum 41 through the through hole.

  In the first nano e-course, the step of sterilizing and deodorizing the inside of the washing / drying machine, the rotational speed of the blower fan 74 is 5000 rpm for 5 minutes from the start of operation, and the rotational speed thereafter is 3000 rpm. . In the present embodiment, the heat pump unit 66 is attached, and the heat pump unit 66 is operated for 5 minutes from the start of operation to control the humidity in the water tank 44 to be lowered. This is because the humidity in the water tank 44 is usually 90% or higher because of the residual water and the high degree of sealing, but the humidity is 85% or less in order to stably generate electrostatic atomization. Therefore, for a predetermined time immediately after the start of operation, the heat pump unit 66 is operated to perform dehumidification for reducing the humidity in the water tank 44.

  However, when the heat pump unit 66 is in operation, the humidity in the water tank 44 may drop at a stretch, and the electrostatic atomization generation by the electrostatic atomization generation unit 81 may become unstable. The electroatomization generating unit 81 is controlled to stop.

  In the present embodiment, the first nanoecourse for sterilization and deodorization inside the washing / drying machine is controlled in 60 minutes, so that the operation time of the first nanoecourse is basically 5 minutes for the dehumidification process. The mold prevention process is 55 minutes. That is, for the first 5 minutes, the heat pump unit 66 is operated and the rotational speed of the blower fan 74 is operated at 5000 rpm, and for the subsequent 55 minutes, the heat pump unit 66 is stopped and the rotational speed of the blower fan 74 is increased. The electrostatic atomization generating unit 81 is operated at 3000 rpm. However, the driving time of the first nanoe course is not limited to this, and a shorter speedy course or a longer lengthy course may be set.

  In FIG. 4, when there is no clothes in the rotary drum 41 and the nanoecourse is selected by the input setting means 77 of the operation panel unit 60 and the operation is started, the lid opening / closing detection means for detecting the opening / closing of the lid 80. When 83 detects the open state of the lid 80, the fan motor 75 for blowing and the electrostatic atomization generating unit 81 are operated, and the charged fine particle water generated from the electrostatic atomization generating unit 81 is covered through the circulation air path 72. The product is discharged from 80 to the outside of the laundry dryer, and sterilization and deodorization in the room where the laundry dryer is installed are started.

  However, in the second nano e-course, the step of sterilizing and deodorizing the outside of the washing / drying machine is provided with a 5-minute dehumidification step of stopping the electrostatic atomization generating unit 81 as in FIG. . During this time, the rotational speed of the blower fan 74 is 3000 rpm, and the rotational speed thereafter is 5000 rpm.

  In the present embodiment, the second nanoecourse for sterilization and deodorization outside the washing / drying machine is controlled in 600 minutes, so that the operation time of the second nanoecourse is basically 5 minutes for the dehumidification process. The mold prevention process is 595 minutes. That is, for the first 5 minutes, the heat pump unit 66 is operated and the rotational speed of the blower fan 74 is operated at 3000 rpm, and for the subsequent 595 minutes, the heat pump unit 66 is stopped and the rotational speed of the blower fan 74 is increased. The electrostatic atomization generating unit 81 is operated at 5000 rpm. However, the operation time of the second nano ecourse is not limited to this, and a shorter setting or a longer setting corresponding to the size of the washing / drying machine installation space may be performed.

  3 and FIG. 4, when the detection result of the lid open / close detection means 83 and the operating conditions do not match, for example, the user can disinfect and deodorize outside the washing / drying machine. In order to do this, the lid 80 is opened, and the lid opening / closing detection means 83 detects that the lid 80 is open and the course operation is started, but the rotational speed of the blower fan 74, that is, the blower fan motor 75 rotates at 5000 rpm. When the operation is started, an abnormality display is immediately displayed on the display means 78 of the operation panel unit 60 and a notification is given to perform control for preventing unnecessary operation.

  As described above, when nanoecourse is selected by the input setting unit 77, the lid opening / closing detection unit 83 detects the opening / closing of the lid 80, and drives the electrostatic atomization generating unit 81, the air blowing unit 64, etc. By operating the first nanoecourse or the second nanoecourse, not only sterilization and deodorization inside the washing / drying machine, but also sterilization / deodorization inside the washing / drying machine installation place is easy and inexpensive. Can be done.

  In addition, by setting the operation time of the second nanoecourse that is operated by detecting the open state of the lid 80 longer than the first nanoecourse that is operated by detecting the closed state of the lid, the washing and drying machine Since a large amount of charged fine particle water is released into a wide space such as a washroom where it is installed, sufficient sterilization and deodorization can be performed.

  In addition, when the operation details of the first nanoecourse or the second nanoecourse do not match the opening / closing detection result of the lid 80, the display means 78 displays an abnormality to notify the user and improve immediately. Can be encouraged.

  As described above, the washing and drying machine according to the present invention detects and controls the opening and closing of the lid, thereby supplying charged fine particle water to a tank inside the machine or an installation place outside the machine, Since it becomes possible to deodorize, it can be applied to other household appliances such as washing machines.
