BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laundry dryer for washing and drying clothes, and more particularly, to a laundry dryer having a function of removing pollen attached to clothes.

BACKGROUND ART A clothes dryer has been conventionally proposed in which a flower pot attached to clothes is detached by a tumbling effect by drum rotation, and a flower pot filter installed in the drum removes it. For example, Japanese Patent Application No. 3037063 and Japanese Patent Application Laid-Open No. 2000-167299 are disclosed.

Nowadays, however, the mainstream is the laundry dryer which completes all the processes from washing to drying, that is, washing, rinsing, dehydrating and drying in the same washing tank. And a laundry dryer excellent in the convenience of use which has the function of removing a pot from clothing is desired.

The laundry dryer according to the present invention includes an outer tub that can be elastically suspended in a housing, an inner tub that is rotatably supported in the outer tub, and clothing is introduced, and a rotor blade rotatably installed at the bottom of the inner tub. And drive means for driving the inner tank or the rotor blade, blowing means blown in the inner tank, heating means for heating the air blown by the blower, and pollen collecting arranged in a path through which the air blown by the blower passes. It is provided with a filter.

Here, the laundry dryer has a driving course for removing the pollen attached to the clothes, at least by the rotation of the rotor blades or blowing by the blowing means.

EMBODIMENT OF THE INVENTION Hereinafter, the Example of this invention is described, referring drawings.

First embodiment

1 is a cross-sectional view of the laundry dryer of the first embodiment of the present invention. The housing 1 of the washing machine elastically suspends the outer tub 3 therein by the suspension 2. The inner tub 5 rotatably supported in the outer tub 3 has a fluid balancer 7 at the top and a plurality of dehydrators 6 at the side walls.

The rotor blade 8 formed in the pot shape as the inclined surface is arrange | positioned at the bottom part of the inner tank 5. As shown in FIG. The rotor blade 8 has a plurality of drain holes 9.

The motor 11 attached to the bottom of the outer tub 3 drives the inner tub 5 or the rotor blade 8 via the transmission mechanism 10 and the dual structural shafts 4 of the washing shaft and the dehydration shaft. The transmission mechanism 10 incorporates a reduction gear (not shown) of the washing shaft and a switching clutch (not shown) of the washing shaft and the dehydration shaft.

The clothing amount detecting means (not shown) rotates the rotor blades 8 for each of the clothes put into the inner tub 5, and detects the amount of clothes from the torque and the inertia rotation of the motor 11 at that time.

The blowing fan 12 sends the air warmed by the heater 13 to the inner tank 5 through the duct 14. The pollen collecting filter 15 is provided upstream of the blowing fan 12, that is, on the intake side. A cover 16 having a clothes loading lid 17 is disposed on the top of the outer tub 3.

The cover 16 has an exhaust 16a for discharging the air sent by the blowing fan 12 into the inner tank 5. An exhaust filter 18 is provided in the exhaust portion 16a. The blowing fan 12 sucks both the outside of the laundry dryer and the exhaust from the exhaust filter 18. The drain part 19 is provided in the bottom face of the outer tub 3.

The operation and action of the laundry dryer configured as described above will be described.

First, the case where the pot attached to the outdoor dry clothing is removed will be described. Outdoor dry clothing is attached to pots that scatter the air. Pollen scattering is particularly common in Japan from February to June when pollen caused by cedar and cypress is scattered, but pollen of plants that can become allergens almost all year round. When bringing outdoor dry clothing, pollen enters the room, and the symptoms of pollen may worsen by inhaling it. In outdoor dry clothing, there is a possibility that 1000 to 2000 flower pots are attached to each shirt at the time of cedar flowerpot scattering peaks.

In order to remove the pollen attached to the outdoor dry clothing, first, the clothing input lid 17 is opened, and the clothing is introduced into the inner tank 5. Next, a driving course for carrying out the pot removal of outdoor dry clothing is selected. In this driving course, driving of the rotor blade 8 and blowing by the blower fan 12 are performed. The driving pattern of the rotor blade 8 is left and right rotation, for example, as shown in FIG. Pollen tends to settle in the atmosphere due to its specific gravity.

The potted plant settled by shaking is passed through the dehydration port 6 or the drain port 9 and is recovered to the bottom of the outer tank 5. When bringing dry or worn clothing to the indoors, it is effective to shake off the pollen by blowing it out outdoors, but the driving of the rotor blade 8 removes the pollen from the garment mechanically and automatically at a higher capacity. This function is extremely useful because a person with hay fever is not able to shake off pollen outside. Since most of the pollen collected at the bottom of the outer tub 5 is water-soluble, the allergen is dissolved in a large amount of water at the next washing, and flows out of the machine from the drain 19. The pollen floating in the air exits the exhaust filter 18 by blowing air by the blowing fan 12 and is collected by the pollen collecting filter 15 disposed on the intake side of the blowing fan 12.

Next, the case of operating through washing to drying is demonstrated. Since the pollen attached to the garment is almost washed off at the time of washing, the pollen attached to the garment is mostly included in the air drawn in during the drying process. Since all the air to be sucked in passes through the pollen collecting filter 15 disposed on the intake side of the blowing fan 12, the pollen is collected at a predetermined efficiency here. The potted plant penetrated into the inner tank 5 through this is recovered to the bottom of the outer tub 5 in the same manner as when the potted plant attached to the outdoor dry garment is removed when the garment is near the end of drying. Or collected in the pollen collecting filter 15. Thus, the pollen attached to the garment can be removed using a pulsator.

In the driving course of removing the pollen attached to the outer dry clothes described above, the driving pattern of the rotor blade 8 is controlled as follows so as not to damage the garment at a rotational force more than necessary of the rotor blade 8,

① The amount of clothing is detected by the clothing amount detecting means.

② Adjust ON / OFF time or driving time of rotor blade 8 according to the amount of clothes.

In this embodiment, the on / off time of the rotor blade 8 is the same in the case of removing the pollen attached to the outdoor drying clothes and in the case of driving through the laundry drying.

Second embodiment

3 is a cross-sectional view of the laundry dryer of the second embodiment of the present invention. The same parts as in the previous embodiment will be denoted by the same reference numerals and the description thereof will be omitted. At the upstream side of the pot collecting filter 15, a lint filter 20 for collecting yarn, hair, etc. is disposed, and the pot collecting filter 15 and the lint filter 20 can be detached as a unit. Configure.

The pollen collecting filter 15 provided on the intake side of the blowing fan 12 passes almost all of the air intaken by the blowing fan 12. Since the air sucked by the blower fan 12 includes the air exhausted from the exhaust filter 18 in the inner tank 5, there is a possibility that the blower fan 12 may contain yarn fuzz, hair, and the like discharged when drying clothes.

The pollen collecting filter 15 is a filter capable of capturing fine particles of 20 to 40 µm, and is simply filled when large to small particles are collected at the same time. Thereby, by arranging the filter stepwise from coarse to fine and making it a plurality of filter structures, clogging of a filter can be alleviated and the fall of the air volume in a path | pass can also be prevented. As a result, the life of the filter also becomes long.

In addition, the pollen collecting filter 15 is not particularly problematic if the dust collecting efficiency around 20 to 40 μm that can collect the pollen can be ensured.

As shown to FIG. 4A and FIG. 4B, it is comprised so that the pollen collecting filter 15 and the lint filter 20 may be integrated as a filter unit. This configuration reliably protects the pollen collecting filter 15, eliminates the trouble of inserting and removing a plurality of filters, and improves convenience of use. Since the pot collecting filter 15 is detachably fixed on the lint filter 20, both filters can be cleaned individually.

Third embodiment

5 is a cross-sectional view of the laundry dryer of the third embodiment of the present invention. The same parts as in the previous embodiment will be denoted by the same reference numerals and description thereof will be omitted. The circulation path 21 which connects the bottom part of the outer tank 3 and the upstream side of the lint filter 20 is provided, and the warm air by the blowing fan 12 is circulated. The circumference of the clothing input lid 17 is sealed to prevent air leakage.

Since the warm air by the blowing fan 12 circulates through the warm air circulation path 21, there is no introduction of outside air. Therefore, the pollen contained in the outside air does not enter the circulation path 21, so that when the pot is removed by putting the outdoor dry clothing into the inner tank 5, the pollen can be efficiently removed.

The potted plants settled by shaking outdoor dry clothes are recovered at the bottom of the outer tub 3, and the potted plants sucked up through the hot air circulation path 21 are collected by the potted plant collection filter 15.

The pollen collection by the pollen collecting filter 15 is carried out continuously as long as the air in the circulation path 21 circulates, so that the pollen is collected not in one pass but in a continuous pass. Thereby, the dust collection efficiency by the pollen collecting filter 15 can be improved significantly.

In addition, when water is supplied into the warm air circulation path 21 to cool the water to have an effect as a heat exchanger, the effect of washing the pot with water occurs and the pot removal capability is improved.

As described above, the laundry dryer according to the present invention can remove the pollen attached to the clothes or the pollen sucked into the washing tank by a blowing means, thereby reducing the allergens that are the source of allergy symptoms. In addition, it is possible to propose a new method of removing allergens from laundry dryers, and also to apply them to equipment for removing allergens other than pollen air purification or pollen.
