  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

(Embodiment 1)
FIG. 1 is a side sectional view of a washing / drying machine according to Embodiment 1 of the present invention.

In FIG. 1, a casing 1 of a washing machine elastically supports an outer tub 3 in its interior by a suspension 2. The inner tub 5 rotatably supported by the outer tub 3 has a number of dewatering holes 6 on the side wall, a fluid balancer 7 at the upper part of the inner periphery, and a pan type with an outer periphery inclined at the center bottom. A rotating blade 8 formed in a shape is disposed. A number of drain holes 9 are provided on the surface of the rotary blade 8.

  The driving means for rotationally driving the inner tub 5 and the rotor blade 8 includes a transmission mechanism unit 10 and a motor 11. The transmission mechanism unit 10 includes therein a reduction gear (not shown) for washing and a switching clutch (not shown) for the washing / dehydrating shaft 4. The motor 11 is attached to the bottom of the outer tub 3 and transmits its power to the washing / dehydrating shaft 4 which is hollow and has a biaxial structure.

  The cloth amount detection means (not shown) detects the amount of clothes by rotating the rotating blade 8 together with the clothes put into the inner tub 5 and confirming the torque and inertial rotation level applied to the motor 11 at that time. It is.

  The blower fan 12 which is a blower means sends the air heated by the heater 13 which is a heating means to the inner tank 5 through the duct 14. The pollen collecting filter 15 is provided on the upstream side of the blower fan 12, that is, on the intake side. Above the outer tub 3, an outer tub cover 16 provided with a clothing input lid 17 is disposed.

  On the outer tank cover 16, an exhaust part 16a for discharging the air sent into the inner tank 5 by the blower fan 12 to the outside is disposed, and an exhaust filter 18 is provided there. . The intake air of the blower fan 12 is configured to suck both the outside air of the washing / drying machine and the exhaust gas from the exhaust filter 18. A drainage means 19 for discharging the water stored in the outer tub 3 is provided on the bottom surface of the outer tub 3.

  In the washing / drying machine, control means (not shown) for controlling the operation of the driving means, the air blowing means, and the heating means is disposed.

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

  As a means of finishing clothes, this washing and drying machine is equipped with an “outside drying finish” course that removes pollen from the clothes that have been air-dried, and a “pollen removal drying” course that removes the pollen remaining on the clothes as it dries. ing. First, the case where the pollen attached to the clothes which are dried outside is removed will be described.

  Pollen that scatters in the atmosphere adheres to clothes that have been dried outside. Pollen scattering is particularly high in terms of the amount of cedar and cypress from February to June, but the pollen of some plants that can be allergens is scattered almost all year round. It is well known that pollen is brought into the room when taking in clothes that have been air-dried, and the symptom of hay fever is further exacerbated by inhaling it. There is a possibility that 1000 to 2000 pollens per T-shirt may adhere to the clothes that have been dried outside at the peak of cedar pollen scattering.

  In order to remove pollen adhering to the outer clothes, the clothes input lid 17 is first opened, and the clothes that have been externally dried are put into the inner tank 5. Next, a course for performing pollen removal finishing of the outer-dried clothes is selected, and a predetermined operation is performed. This course is operated by an operation involving driving of the rotary blades 8 and blowing by the blower fan 12. Not only is the wind generated and the pollen collecting filter 15 collects the pollen, but the clothes thrown in by the movement of the rotary blade 8 are shaken to settle the pollen. This utilizes the property that pollen tends to settle in the air due to its specific gravity.

The pollen that is shaken and settled passes through the dewatering hole 6 and the drain hole 9 and is collected at the bottom of the outer tub 5. It is effective to drop the pollen by shaking it off the outside when taking clothes outside or wearing clothes indoors. However, the driving of the rotor 8 is mechanically and automatically pollen with a higher capacity. This function is extremely useful because it is something that is removed from clothing, and it is impossible for a person with hay fever to shake off pollen outside.

  Here, most of the pollen collected in the bottom of the outer tub 5 is dissolved in a large amount of water at the time of the next washing because the allergen substance is water-soluble, and is discharged from the drainage means 19 to the outside of the machine. The floating pollen rides on the air blown by the blower fan 12, passes through the exhaust filter 18, and is collected by the pollen collecting filter 15 disposed on the intake side of the blower fan 12.

  The operation is the same when finishing and drying the outer-dried clothes by applying heat.

  Next, a case where the selective dryer is operated from washing to drying will be described.

  At the time of washing operation, even if there is pollen remaining on the clothes, it will be washed away and hardly remains. Since the process proceeds directly to the drying process, most of the pollen adhering to the clothing is contained in the air sucked for drying. In this case, all of the intake air passes through the pollen collection filter 15 disposed on the intake side of the blower fan 12, and is thus collected here with a predetermined dust collection efficiency.

  When pollen enters the inner tub 5 after passing through this, when the clothing is almost in a dry state, the same mechanism as in the case of removing the pollen attached to the outer-dried clothing is used. , Collected at the bottom of the outer tub 5 or collected by the pollen collecting filter 15.

  In any case, through these operations, it becomes possible to remove the pollen attached to the clothes by the pulsator method. It is difficult to give mechanical power evenly. In the above-described drum system, the entire drum rotates, so mechanical force is applied to the garment relatively uniformly. However, in the pulsator system, mechanical force is applied only to the bottom of the inner tub 5 that is a part of the garment. End up.

  In order to eliminate this, it is necessary to prevent the mechanical force from being locally applied as much as possible by rolling the entire garment in the inner tub 5. Therefore, an optimized rotation sequence of the rotary blade 8 that can roll the entire clothing in the inner tub 5 even if the amount of clothing is large is repeated so that shaking and rolling are repeated.

  More specifically, the rolling means 8 has a drive for rotating the rotor blade 8 while changing the rotational speed at a first target rotational speed and a second target rotational speed different from the rotational speed in the same rotational direction by the driving means. The target first sequence and the second sequence for the purpose of removing pollen by shaking that repeats the same left-right inversion at the same rotation number are continuously repeated. The first sequence takes a drive time longer than normal agitation, which is sufficient to roll the entire garment greatly, and the second sequence draws the shaking effect by repeating the same left and right inversion.

  When the second target rotational speed is set to be larger than the first target rotational speed, the entire garment is first placed on the rotary blade 8 at the first target rotational speed, and then the second target rotational speed is set. By rotating at the target rotational speed, slippage and idle rotation due to a sudden application of rotational force to the garment can be prevented, and the garment rolling can be increased more reliably.

  In addition, by setting the time period driven at the second target speed higher than the time period driven at the first target speed, the clothes in the inner tub 5 rolls up and down largely. It is possible to eliminate a decrease in pollen removal performance, unevenness, variation and the like due to a large amount of clothing and mechanical force applied only below the inner tub 5.

  FIG. 2 shows an example of the movement of the rotary blade 8 that shakes the thrown-in clothes and settles pollen.

  In the present embodiment, the stirring time of the rotary blade 8 is the same for removing pollen from the clothes that have been air-dried and for washing and drying through operation.

  In addition, before performing the operation of driving the rotary blade 8 while performing blowing by the blowing means, the amount of clothes put in the inner tub 5 is detected by the cloth amount detecting means, and the first amount is determined according to the amount of clothes. If the rotation time or operation time of the rotor blades in the sequence 1 and the second sequence is changed, the rotor blades are especially useful when it is necessary to take care of clothing damage, such as when removing pollen by finishing the outer-dried clothing. The agitation strength or rotation time during left-right rotation of the garment is adjusted in accordance with the amount of clothing, so that pollen can be removed with good finish of the clothing.

  As described above, the washing / drying machine according to the present invention efficiently removes pollen adhering to clothes and pollen sucked into the washing tub by air blowing means from the clothes efficiently and uniformly. It can be removed as a sieve to remove allergens, and can be widely applied to domestic and commercial washing and drying machines.
