Japanese Patent No. 3037063 JP 2000-167299 A

  In recent years, washing and drying machines that can be operated through from washing to drying have become mainstream. This completes the entire process of washing, rinsing, dehydration and drying in the same washing tub.

  However, in the conventional drum system, a pollen collecting filter must be disposed in the washing tub, and it is difficult to remove pollen with the same configuration in the washing dryer in terms of configuration. In addition, there are two types of washing and drying machines: the pulsator method used mainly in Japan and the drum method used in Europe. In the case of the pulsator method, it is not possible to apply mechanical force by tumbling.

  The present invention solves the above-mentioned conventional problems, including pulsator-type ones, which can be washed and dried while removing pollen from clothes, and pollen adhered to clothes on the outside where pollen tends to scatter. An object of the present invention is to provide an easy-to-use washing and drying machine that can be reliably removed.

  In order to solve the above-described conventional problems, a washing and drying machine according to the present invention includes an outer tub that is elastically supported in a casing, an inner tub that is rotatably supported in the outer tub, and is loaded with clothes. A tank, a rotating blade provided rotatably at the bottom of the inner tank, a drainage means for discharging water stored in the outer tank provided at the bottom of the outer tank, and the inner tank or the rotating blade. Driving means for driving, blowing means for blowing air into the inner tub, heating means for heating air blown by the blowing means, and pollen disposed in a path through which the air blown by the blowing means passes A pollen removal drying course for drying the clothes while removing the pollen attached to the clothes by rotating the rotating blades and operating the heating means while operating the heating means while removing the pollen attached to the clothes. Without rotating the rotor. Has a pollen removing air course that removes pollen adhered to the clothing by air blown by the air blowing means, and the pollen removing air course rotates the rotor blades with the air blowing means stopped at the beginning of operation. The pollen is removed from the clothing and collected at the bottom of the outer tub, and after a predetermined time, the air blowing means is operated to blow the air. Pollen can be removed by collecting and collecting the pollen in the path that has risen without settling by filtering with a pollen collection filter. During the pollen removal drying course, pollen contained in the drying air sucked from the outside is collected by the pollen collection filter, so that new pollen can be prevented from adhering to the clothing. In addition, for clothes that have been dried outside, the pollen is also dry and is in a state of being easily scattered. The pollen is removed from the clothing and collected at the bottom of the outer tub, and after a predetermined time, the pollen in the path can be collected by filtering with a pollen collection filter by blowing air, so it is necessary with the rotational force of the initial rotating blades The pollen that has danced as described above can be collected more reliably by the pollen collection filter.

  In addition, most of the pollen collected at the bottom of the outer tub can be dissolved in a large amount of water at the time of the next washing and flowed out of the machine from the drainage means because the allergen substance is water soluble.

  The washing / drying machine of the present invention can wash and dry while removing pollen, and can also reliably remove pollen from clothes on the outside.

  According to a first aspect of the present invention, there is provided an outer tub that is elastically suspended in a housing, an inner tub that is rotatably supported in the outer tub and into which clothing is put, and a bottom portion of the inner tub that is freely rotatable. A rotating blade provided, a draining means for discharging water stored in the outer tank provided on the bottom surface of the outer tank, a driving means for driving the inner tank or the rotating blade, and an air flow into the inner tank A heating means for heating the air blown by the blowing means, and a pollen collecting filter disposed in a path through which the air blown by the blowing means passes, and operates the heating means A rotating course of the rotating blades and a pollen removing drying course for drying the clothes while removing pollen adhering to the clothes with warm air from the blowing means, and rotation of the rotating blades without operating the heating means or the Attached to the clothing by blowing air A pollen removal blowing course for removing pollen, and the pollen removal blowing course sifts off pollen from clothing by rotating the rotating blades with the blowing means stopped at the beginning of operation. It is collected at the bottom, and after a predetermined time, the air blowing means is operated so as to blow air. By rotating the rotor blades, pollen is removed from the clothing and collected at the bottom of the outer tub, and it rises without sinking. Pollen can be removed by filtering and collecting pollen in the path with a pollen collecting filter. During the pollen removal drying course, pollen contained in the drying air sucked from the outside is collected by the pollen collecting filter, so that new pollen can be prevented from adhering to the clothing. In addition, for clothes that have been dried outside, the pollen is also dry and is in a state of being easily scattered. In the atmosphere, pollen tends to settle due to its specific gravity. The pollen is removed from the clothing and collected at the bottom of the outer tub, and after a predetermined time, the pollen in the path can be collected by filtering with a pollen collection filter by blowing air, so it is necessary with the rotational force of the initial rotating blades The pollen that has danced as described above can be collected more reliably by the pollen collection filter.

  In addition, most of the pollen collected at the bottom of the outer tub can be dissolved in a large amount of water at the time of the next washing and flowed out of the machine from the drainage means because the allergen substance is water soluble.

According to a second aspect of the present invention, in the first aspect of the invention, the air volume of the air blowing means is lowered during the pollen removal air course operation compared to the pollen removal air course operation. The pollen that has been shaken off by the rotor blades is more likely to scatter than the clothes that are used, and there is a risk of pollen leaking in addition to the pollen collection filter at the same air volume as dry. By reducing the air volume of the blowing means, pollen can be reliably filtered and collected without scattering pollen more than necessary.

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

In addition, a first course setting switch 21h and a second course setting switch 21i are provided.

  The first course setting switch 21h sets a course to be driven, a course for performing a series of steps of washing, rinsing, dehydration, and drying, a course for performing steps of washing, rinsing, and dehydration, and a drying step only. The course to be performed can be switched and set in the above order each time it is turned on.

  The second course setting switch 21i is used to switch between an automatic course, a rush course, a private course, a blanket course, a one hour washing course, and the like so that it can be switched in the above order each time it is turned on. Yes.

  The display means 22 includes a washing time display unit 22a, a rinse count display unit 22b, a dehydration time display unit 22c, a drying time display unit 22d, and a course setting display unit 22e for displaying a course set by the second course setting switch 21i. have. Moreover, it has the detergent amount display part 22f, the remaining time display part 22g, and the number display part 22h.

  Here, the washing time display unit 22a, the number of times of rinsing display unit 22b, the dehydration time display unit 22c, and the drying time display unit 22d are each composed of a plurality of segments. That is, the washing time display part 22a is composed of five segments (5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes), and the rinse number display part 22b is (1 time, 2 times, 3 times, 4 times, water injection), and the dehydration time display unit 22c is composed of 4 segments (1 minute, 3 minutes, 6 minutes, 12 minutes), and the drying time display unit 22d is a red LED. (30 minutes, 60 minutes, automatic) composed of three segments (pollen removal drying course display section) of the pollen removal drying course 22d-1 and a pollen removal ventilation course 22d-2 (air blowing composed of green LEDs) 10 segments), a total of four segments of one segment (pollen removal blow course display section).

  Further, every time the drying time setting switch 21d is operated, the LEDs selected in the order of 30 minutes → 60 minutes → automatic → blowing 10 minutes → lighting off of the drying time display portion 22d arranged in a ring shape around it are turned on. To do. And when pollen removal ventilation course 22d-2 (fan 10 minutes) is selected, washing, rinsing, and dehydration cannot be selected.

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

  First, a description will be given of the case of removing pollen from the clothes that have been air-dried. 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 are put into the inner tub 5. Next, the drying time setting switch 21d is operated to select the pollen removal blow course 22d-2 (10 minutes blow) and perform a predetermined operation. This course is operated by an operation involving driving of the rotary blades 8 and blowing by the blower fan 12. At this time, the rotary wing 8 is rotated left and right, thereby shaking the garment thrown in and causing the pollen to settle. 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 3. 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 at the bottom of the outer tub 3 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. Further, in the case of clothes that have been air-dried or worn, the pollen is also dry, and in the initial stage when the rotor 8 is driven, a large amount of the pollen floats in comparison with wet clothes. When the blower fan 12 is driven at a high speed in this state, the pollen collecting filter 15 cannot reliably collect the pollen, and the pollen may leak out of the washing / drying machine. Therefore, as shown in FIG. 3, first, the rotor 8 is driven, and the blower fan 12 is rotated at 2000 r / min after two minutes after the pollen floating has settled. The pollen collecting filter 15 disposed on the intake side of the blower fan 12 is surely collected.

  Also, when this pollen removal air course 22d-2 (air blowing 10 minutes) is selected, washing, rinsing, and dehydration cannot be selected, so use this when you want to care for the outside clothes after selection. It is possible to prevent a person from accidentally washing clothes and getting wet.

  Next, the case where it drives from washing to drying is demonstrated.

First, clothes are put in, the course to be operated is operated by operating the first course setting switch 21h, and the course for performing a series of steps of rinsing, dehydration and drying is set. As for the drying time, if the drying time setting switch 21d is operated and set to (automatic) in the drying time display portion 22d, the end of drying is detected and the operation is automatically ended. In the case of this course, even if there is pollen remaining on the clothes during washing operation, it will be washed away and hardly remains. Since the process proceeds to the drying process as it is, most of the pollen adhering to the clothing is contained in the air sucked for drying. As described above, the wet clothes after dehydration have a small amount of adhering pollen, and the amount of pollen floating by driving the rotary blade 8 is small. In this case, as shown in FIG. 4, as a sequence of the pollen removal drying course, the rotary blade 8 is driven, and the blower fan 12 that is the blowing means is rotated at 4000 r / min necessary for drying the clothes, thereby the heater 13. Is driven to send warm air through the duct 14 to the inner tub 5 to dry the clothes. Further, since all of the air that is taken in passes through the pollen collection filter 15 disposed on the intake side of the blower fan 12, it is 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 pollen attached to clothing by the pulsator method.

  Further, the drying time display unit 22d has a total of 4 segments of 3 segments of the pollen removal drying course 22d-1 (30 minutes, 60 minutes, automatic) and one segment of the pollen removal blow course 22d-2 (fan 10 minutes). It is composed of two segments, and every time the drying time setting switch 21d is operated, it can be selected in the order of 30 minutes → 60 minutes → automatic → 10 minutes blowing → turn off of the drying time display section 22d arranged around it. Therefore, the pollen removal drying course 22d-1 and the pollen removal blow course 22d-2 cannot be set at the same time so that the display space can be used effectively and the operability can be improved. And the segment which displays pollen removal drying course 22d-1 (30 minutes, 60 minutes, automatic) by red LED, and the segment which displays pollen removal ventilation course 22d-2 (fan 10 minutes) are comprised by green LED. Therefore, even in the same drying time display portion 22d, it is possible to inform the user that the courses are different from each other in an easy-to-understand manner, and the visibility can be improved.

  As described above, the washing / drying machine according to the present invention can remove pollen adhering to clothes and pollen sucked into the washing tub by a blowing means regardless of clothes to be washed and clothes to be dried outside. Therefore, not only can allergens, which are the root cause of allergic symptoms, be reduced, but also new ways of removing allergens in laundry dryers can be proposed, as well as equipment for air purification in laundry spaces and removal of allergen substances other than pollen. Applicable.
