(Indicated by a dashed line in FIG. 4).

  Next, a series of operations for performing a washing operation, a rinsing operation, a dehydrating operation, a drying operation, and a charge eliminating operation in the vertical washing dryer will be described. The static elimination operation may be performed at least after the drying operation.

<Laundry operation>
First, after putting laundry and detergent into the washing tub 3, the door 4 is closed, the operation section 5 a (shown in FIG. 3) is selected to select the washing condition, and the start button is pressed. Starts washing operation.

  In this washing operation, the control device 100 opens the water supply valve 80 to supply a predetermined amount of water into the washing tub 3 and then closes the water supply valve 80.

  Next, the rotating shaft 31a of the clutch / brake mechanism 31 is connected to the stirring blade 20 by the clutch operation of the clutch / brake mechanism 31, and the drive motor 32 is driven. Thereby, the stirring blade 20 rotates and the water in the washing tub 3 is stirred.

  Then, after a predetermined time has elapsed from the start of the washing operation, the drive motor 32 is stopped to end the washing operation.

<Dehydration operation>
Next, the control device 100 starts the dehydration operation. In this dehydration operation, the controller 100 connects the rotating shaft 31a of the clutch / brake mechanism 31 to the washing tub 3 by the clutch operation of the clutch / brake mechanism 31, and drives the drive motor 32. As a result, the stirring blade 20 also rotates together with the washing tub 3.

  As the washing tub 3 rotates at a high speed, the laundry is pressed against the peripheral wall of the washing tub 3 by centrifugal force, and the washing water contained in the laundry is discharged from a dewatering hole (not shown) of the washing tub 3. Released and received by the inner surface of the water tank 2. The washing water received on the inner surface of the aquarium 2 is drained to the outside from the bottom of the aquarium 2 through the drainage hose.

  Then, after a predetermined dehydration time has elapsed from the start of the dehydration operation, the control device 100 stops the drive motor 32 and stops the rotation of the washing tub 3 by braking by the clutch / brake mechanism 31.

<Rinse operation>
Next, the control device 100 starts the rinsing operation. In this rinsing operation, the control device 100 opens the water supply valve 80 to supply a predetermined amount of water to the washing tub 3.

  Then, the rotation shaft 31a of the clutch / brake mechanism 31 is connected to the stirring blade 20 by the clutch operation of the clutch / brake mechanism 31, and the drive motor 32 is driven. Thereby, the stirring blade 20 rotates and the water in the washing tub 3 is stirred.

  In this rinsing operation, water supply, agitation, and drainage are performed once or a plurality of times.

<Dry operation>
Next, the control device 100 starts the drying operation. In the first stage of the drying operation, as shown in FIG. 4, the control device 100 opens the reflux duct 42 and closes the outside air introduction duct 41 by the switching valve 61 of the air path switching mechanism 40, and sets the drying mode to “ The inside air circulation mode is set.

  Next, the blower fan 52 is driven to energize the heater 60. As a result, hot air is blown into the washing tub 3 from the blowing duct 43 to heat the laundry in the washing tub 3, and then returns to the blower fan 52 through the reflux duct 42, and the air in the washing tub 3 circulates. To do. The circulation duct 42, the blowing duct 43, and the housing 51 of the blower unit 50 form a circulation path through which the air in the washing tub 3 circulates via the heater 60.

  In this “inside air circulation mode”, since warm air does not go out of the vertical laundry dryer, heat is trapped inside the washing tub 3 and the temperature inside the washing tub 3 rises quickly. In addition, the control device 100 rotates the washing tub 3 at a rotation speed lower than the rotation speed during the dehydration operation so that the warm air uniformly hits the laundry in the washing tub 3.

  As the temperature inside the washing tub 3 rises, moisture evaporates from the laundry, and the air in the inside air circulation contains a lot of moisture. When the temperature sensor 23 detects that the internal temperature of the washing tub 3 has risen to a predetermined value, the control device 100 switches the drying mode to the next “mixing circulation mode”.

  FIG. 5 is a schematic cross-sectional view in the “mixing circulation mode” of the vertical washing dryer. In FIG. 5, the same components as those shown in FIGS. 1 and 2 are denoted by the same reference numerals.

  In this “mixed circulation mode”, the switching valve 61 of the air path switching mechanism 40 closes the outside air introduction duct 41 and opens the reflux duct 42 (shown in FIG. 4), and closes the reflux duct 42 and closes the outside air introduction duct 41. Is in the middle of the open state (shown in FIG. 6). As a result, air flows into the blower fan 52 from both the reflux duct 42 and the outside air introduction duct 41, so that the amount of air sucked into the reflux duct 42 is reduced, and the entire amount of air blown out from the blowing duct 43 is received by the reflux duct 42. I can't do that. The air that has not been sucked in by the reflux duct 42 is discharged to the outside through the exhaust duct 45.

  Since the air discharged from the exhaust duct 45 contains a large amount of moisture, the moisture can be efficiently discharged from the washing tub 3. On the other hand, since all of the air in the washing tub 3 is not exhausted from the exhaust duct 45 and part of the air circulates through the reflux duct 42, the high temperature state in the washing tub 3 can be maintained.

  When the humidity in the washing tub 3 detected by the humidity sensor 24 falls below a predetermined value, the control device 100 stops the blower fan 52 and the drive motor 32 and stops energization of the heater 60.

  In the above description, when switching from the “inside air circulation mode” to the “mixing circulation mode”, the switching condition is that the temperature sensor 23 detects that the temperature inside the washing tub 3 has increased to a predetermined value. However, the switching condition may be that the humidity sensor 24 detects that the internal humidity of the washing tub 3 has increased to a predetermined value.

  Further, instead of finishing the drying operation in the “mixing circulation mode”, a drying operation in the “outside air introduction mode” shown in FIG. 6 may be added thereafter. In FIG. 6, the same components as those shown in FIGS. 1 and 2 are denoted by the same reference numerals.

  In FIG. 6, the switching valve 61 of the air path switching mechanism 40 closes the reflux duct 42 and opens the outside air introduction duct 41. In this “outside air introduction mode”, the air in the washing tub 3 is not sucked from the reflux duct 42, and all the air blown from the blow duct 43 is discharged to the outside through the exhaust duct 45.

  The outside air introduction duct 41, the blow-in duct 43, the exhaust duct 45, and the blower unit 50 constitute a ventilation device. The ventilator is not limited to this, and may be a ventilator having another configuration provided separately.

<Static elimination operation>
Next, the control device 100 starts the static elimination operation. In this static elimination operation, as in the “inside air circulation mode” of the drying operation, the switching duct 61 of the air path switching mechanism 40 opens the reflux duct 42 and closes the outside air introduction duct 41 to circulate the air in the washing tub 3. It circulates through the duct 42, the blowing duct 43, and the ventilation unit 50 (refer FIG. 4).

  After the drying operation is completed, in the state where the washing tub 3 and the stirring blade 20 are stopped without rotating, the deionized ions generated by the deionization ion generator 70 are blown into the washing tub 3 by the blower fan 52 through the blowing duct 43. By performing the discharging operation to be supplied, static electricity charged in the laundry can be effectively removed without generating static electricity due to the laundry being stirred and rubbed.

  In addition, as shown in FIG. 2, a part of the static elimination ions generated from the static elimination ion generator 70 is removed by the blowing duct 43 (static elimination ion guide portion) disposed above the upper opening of the laundry tub 3. From the upper side of the washing tub 3 so as to be blown obliquely downward in the direction of the arrow R 1, and a part of the static elimination ions generated from the static elimination ion generator 70 are directed toward the bottom in the laundry tub 3. Guide to blow in the direction of R2. The outlet 43a of the blowing duct 43 is configured to guide the blowing air in the directions of arrows R1 and R2 using a rectifying plate and a nozzle, respectively.

  As a result, it is possible to efficiently supply static elimination ions to the laundry accumulated at the bottom of the washing tub 3.

  Moreover, by discharging the static elimination ions generated by the static elimination ion generator 70 into the washing tub 3 from the outlet of the blowing duct 43 together with the air circulating through the circulation path (the reflux duct 42, the blowing duct 43 and the blower unit 50). In addition, the blower unit 50 (circulation fan) used in the drying operation can also be used as a blower for static elimination ions, and the configuration can be simplified.

  The static elimination operation is terminated when the user operates the power switch of the operation unit 5a to cut off the power supplied to the main body, or the door 4 is opened to take out the laundry from the washing tub 3. Next, the process is ended when the door 4 is closed.

  In the above-described static elimination operation, it is possible to set whether or not the static elimination operation is performed by a user operation on the operation unit 5a (shown in FIG. 3). Further, during the static elimination operation, the user is informed that the static elimination operation is being performed by a blinking lamp or the like on the display unit 5b (shown in FIG. 3).

  FIG. 7 is a vertical cross-sectional view of the vertical washer-dryer when the door 4 is opened from the side. In FIG. 7, the same components as those shown in FIGS. Are given the same reference numbers.

  As shown in FIG. 7, a part of the static elimination ions generated from the static elimination ion generating device 70 is directed in the direction of the arrow R <b> 1 from the outlet of the blowing duct 43 on the upper side of the washing tub 3 toward the oblique lower side in the washing tub 3. By blowing out, when a user takes out the laundry from the bottom of the washing tub 3, static electricity is supplied to the laundry passing through the upper opening of the washing tub 3 to remove static electricity, and more effective static elimination can be performed. .

  The outlet of the blowing duct 43 is configured to supply static elimination ions to the entire upper opening region of the laundry tub 3 when the laundry is taken out from the laundry tub 3. At this time, the discharge ions collide with the inner wall of the washing tub 3 from the outlet of the blowing duct 43 on the upper side of the washing tub 3 so that the discharge ions collide with the inner wall of the washing tub 3 and the outside of the washing tub 3. To prevent leakage. Further, when the laundry is taken out, since the ion is continuously supplied to the bottom of the washing tub 3 by blowing out toward the bottom of the washing tub 3 in the direction of the arrow R2, the laundry remaining at the bottom of the washing tub 3 is also supplied. The static elimination effect can be maintained for the object.

  In addition, you may make it the setting which generate | occur | produces static elimination ion by dry operation before the start of washing operation. In this case, during the drying operation, the control device 100 operates the static elimination ion generator 70 to discharge static elimination ions into the blowing duct 43. At this time, the discharge ion discharge valve 62 opens the blowing duct 43 and closes the discharge ion discharge duct 44 so that all discharged discharge ions are supplied into the washing tub 3.

  Thus, the static elimination ions blown into the washing tub 3 together with the dry hot air removes static electricity charged in the laundry. The charge removal during the drying operation is not limited to the “inside air circulation mode”, and the charge removal ion generator 70 may be operated in the “mixed circulation mode” or the “outside air introduction mode” to remove electricity.

  Further, when the static elimination ions generated by the static elimination ion generator 70 have functions of sterilization, mold prevention, and deodorization, the static elimination ion release duct 44 is opened and blown by the static elimination ion release valve 62 when washing is not performed. The duct 43 may be partially opened to operate in an “ion release mode” for the purpose of charge removal, sterilization, mold prevention, and deodorization.

<About ionization ion generator>
The neutralization ion generator 70 includes a positive ion generator that generates positive ions and a negative ion generator that generates negative ions. The positive ion generator and the negative ion generator are provided in the static elimination ion generator 70 at a predetermined interval.

In the positive ion generator of the ionization ion generator 70, for example, a 60 Hz (or 50 Hz) alternating current in which a voltage of an effective voltage of 2 kV or more and 0 V are switched is applied to the needle electrode, while a 0 V is applied to the induction electrode. A direct current is applied. When an effective voltage of 2 kV or more is applied to the needle electrode, corona discharge occurs due to the potential difference between the needle electrode and the induction electrode, and water molecules in the air are ionized near the tip of the needle electrode, causing hydrogen ions (H ⁺ ) is generated. The hydrogen ions are combined (clustered) with water molecules in the air in a group state, and positive ions composed of H ⁺ (H ₂ O) _m are generated (m is an arbitrary natural number).

On the other hand, in the negative ion generation part of the static elimination ion generator 70, for example, a 60 Hz (or 50 Hz) alternating current in which a voltage of an effective voltage of −2 kV or less and 0 V are switched is applied to the needle electrode, A direct current of 0 V is applied, and negative ions are generated. The negative ions are oxygen ions (O ₂ ⁻ ) formed by ionizing oxygen molecules or water molecules in the air. The oxygen ions are combined (clustered) with water molecules in the air to generate negative ions composed of O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number).

  In the first embodiment, the positive ion generation unit and the negative ion generation unit energize both the positive ion generation unit and the negative ion generation unit to generate positive ions and negative ions at the same time, and positive ions and negative ions are generated in the air. Mix both ions.

  In addition, the static elimination ion generator is not limited to the above configuration, and may be any device that generates ions having an effect of removing static electricity charged in the laundry.

[Second Embodiment]
Next, a vertical washer / dryer according to a second embodiment of the present invention will be described. The vertical washer / dryer according to the second embodiment has the same configuration as that of the vertical washer / dryer according to the first embodiment except for the operation during the static elimination operation, and FIGS.

  In the vertical washer / dryer of the second embodiment, the driving unit 30 rotates the washing tub 3 during the washing operation during the discharging operation for supplying the discharging ions generated by the discharging ion generator 70 into the washing tub 3. By rotating at a lower rotational speed than the speed, the static-removing ions can be supplied substantially uniformly to the laundry accumulated at the bottom in the washing tub 3, and the charge-removing effect can be enhanced. At this time, the rotation speed of the washing tub 3 is set to a low rotation speed in which the laundry in the washing tub 3 is kept stationary with respect to the washing tub 3 and the laundry does not rub against each other.

  During the static elimination operation, the washing tub 3 may be continuously rotated or the washing tub 3 may be intermittently rotated.

  The vertical laundry dryer of the second embodiment has the same effects as the vertical laundry dryer of the first embodiment.

The vertical washer / dryer of the third embodiment has the same configuration as that of the vertical washer / dryer of the first embodiment except for the operation during the static elimination operation, and FIGS.

  In the vertical washer / dryer according to the third embodiment, when the static elimination operation is performed in the “inside air circulation mode”, the outside air introduction duct 41 is periodically closed by the switching valve 61 of the air path switching mechanism 40. In the “outside air introduction mode”, the air in the washing tub 3 is exchanged with the outside air.

  As a result, even if static electricity moves from the electrostatically charged laundry to the air in the washing tub 3 and stays during static elimination operation, the ventilator (the outside air introduction duct 41, the blowing duct 43, the exhaust duct 45, and the air blowing unit 50). ) By periodically replacing the air in the washing tub 3 with the outside air, the charged air can be discharged to the outside, and the charge removal effect can be improved.

  The vertical laundry dryer of the third embodiment has the same effects as the vertical laundry dryer of the first embodiment.

  A hanger locking portion 4 a is provided on the back side of the door 4. The hanger 200 is hung on the hanger locking portion 4a.

  According to the fourth embodiment, the clothes as an example of the object to be neutralized are suspended in the washing tub 3 by the hanger 200 locked to the hanger locking portion 4a, and the clothes are suspended in the washing tub. On the other hand, by supplying the static elimination ions generated by the static elimination ion generator 70 with the blower fan 52, it is possible to remove static electricity such as clothes worn as well as the laundry after the drying operation. Here, what is hung in the washing tub 3 by the hanger 200 is not limited to clothing as an example of the object to be discharged, but may be an object to be discharged such as a towel, worn clothing, and stored clothing.

  Further, during the static elimination operation, the forward rotation operation and the reverse rotation operation of the stirring blade 20 are alternately and intermittently performed, whereby the static elimination ions in the washing tub 3 are agitated together with the air, and a substantially uniform static elimination effect is obtained. .

  The forward rotation operation and the reverse rotation operation of the stirring blade 20 may be alternately and continuously repeated.

  The vertical laundry dryer of the fourth embodiment has the same effects as the vertical laundry dryer of the first embodiment.
