Description

  The present invention relates to a drum type laundry dryer having a deodorizing mode in which the laundry is dried by heated air and then deodorized by mist after the laundry in a rotating drum is moistened with mist.

  Conventionally, in the drying process, the rotating drum containing the laundry such as clothes is rotated at a high speed, and the laundry is dried while sticking to the inner wall of the rotating drum. It is inevitable that wrinkles enter clothing, and it is necessary to add trouble to stretch the wrinkles when hanging such clothes on a hanger, etc. there were.

  Therefore, recently equipped with an atomizing unit that generates mist consisting of fine droplets, introducing mist into a rotating drum containing clothing, etc., and washing and drying to reduce static electricity and wrinkles that entered clothing etc. in the drying process 2. Description of the Related Art Clothing dryers that dry and deodorize clothing and the like by introducing mist into a dryer or a drying chamber that houses clothing have been developed (see, for example, Patent Documents 1 and 2).

  The washing and drying machine disclosed in Patent Document 1 is an outer tub, an inner tub that is rotatably disposed in the outer tub and accommodates laundry, and after the air in the outer tub is exhausted and dehumidified by a blower fan. Repeated heating and blowing into the outer tub, drying the clothes in the inner tub, provided in the vicinity of the hot air supply port to the inner tub through the heating means of this hot air circulation path, drying In the process, the mist is sprayed into the warm air circulation path. And it is supposed that the static electricity which generate | occur | produces when clothes are stirred in a drying process can be removed, the discomfort to the human body by static electricity can be eliminated, and the wrinkles of the clothes after drying can be reduced. Further, the hot air supply port is located at the rear of the upper surface of the outer tub that is not opened and closed, and dry air and mist are directly introduced into the inner tub from the upper end opening thereof.

  By the way, the atomized mist has different characteristics such as floatability and surface tension (wetting property) depending on the particle size. That is, an ultrafine mist having a particle size of less than 10 μm is also called a dry mist and is extremely fine, and thus has a high surface tension and high floating property, but has low wettability when attached to an object. ing. Fine mist having a particle size of 10 to 50 μm is also called wet mist, and has a relatively large particle size compared to the dry mist described above, and thus has a low surface tension and high wettability when attached to an object. have. A relatively coarse mist having a particle size of more than 50 μm has properties close to water droplets.

  Among these, wet mist with excellent wettability can reduce wrinkles such as clothes in the drying process while adhering to clothes that are laundry and moistening the laundry efficiently. Filling the rotating drum tank with mist containing a large amount of wet mist is important in obtaining the effect of reducing wrinkles such as clothing. Also, when the mist generated in the atomization unit is introduced to the place where the clothing is placed, it should not be collided with the pipe wall of the introduction pipe line as much as possible, that is, condensed and lost to the pipe wall etc. It is important to efficiently send many mists to the place where the clothes are placed.

  The laundry dryers and clothes dryers disclosed in Patent Documents 1 and 2 lack such a viewpoint, and therefore cannot be efficiently dried and deodorized.

  Moreover, in the washing / drying machine disclosed in Patent Document 1, a part of the mist sprayed from the spraying device reaches the clothes in the inner tub as it is, but most of the other collides with the inner wall surface of the hot air circulation path. Most of the water is condensed on the inner wall surface and lost as water droplets before reaching the inner tank. In this washing / drying machine, negative ions are generated due to the crushing effect when the mist collides with the inner wall surface, and the static neutralization effect can be enhanced. However, most of the mist sprayed from the spray device is in the middle. There was a problem that it disappeared and did not reach the clothes in the inner tank, and it was difficult to deodorize effectively by moistening the clothes.

  Moreover, in the clothes dryer disclosed in Patent Document 2, an electrolytic mist generator is disposed in a machine room provided below the bottom plate of the drying chamber, and the generated electrolytic mist is supplied to the downstream side of the heater, After heating the electrolytic mist to a high temperature by mixing with hot air, it is discharged upward from the duct chamber and blown out through the blowout part formed by the bottom plate of the drying chamber in which multiple slits and holes are formed and supplied to the drying chamber is doing. In such a configuration, although a plurality of slits and holes are formed in the blowout part, most of the mist collides with the lower surface of the bottom plate where no slits or holes are formed and condenses to form water droplets. Will be lost. Therefore, in such a clothes dryer, most of the mist generated from the electrolytic mist generator disappears in the middle and does not reach the clothes in the drying chamber. Since hot air was supplied to the room, hot air with high humidity was also introduced into the drying room, and even though some deodorizing effect could be expected, the clothes could not be sufficiently dried.

  In addition, when the mist generating means is an ultrasonic atomization method, the amount of mist generated per hour varies depending on the water temperature, the input voltage to the oscillation circuit, and the like.

  For example, when an ultrasonic transducer that oscillates at 1.6 MHz is used, if other conditions are fixed and only the water temperature is changed from 5 ° C. to 30 ° C., the amount of mist generated is about 1.5 times. Further, if only the voltage input to the oscillation circuit is changed from 95V to 107V, the amount of mist generated is also about 1.5 times here.

  Normally, the water temperature change and the voltage change described above are changes that normally occur at home. Therefore, when the mist generation amount is the minimum condition, the mist generation amount is adjusted by adjusting the drying rate of the clothes from 90% to 96%. However, since the amount of mist generated becomes excessive under the maximum conditions, the clothes become wet to a drying rate of nearly 70%, so that the meaning of using the mist adopted as a means for moistening is lost.

  Conversely, when the amount of mist generated is adjusted so that the drying rate of the garment is 90% to 96% under the maximum condition, there is a problem that under the minimum condition, the garment is almost not wet and the drying rate is only near 99%.

  In addition, mist refreshing by a combination of mist treatment and drying may not always satisfy the finish even if deodorizing and wrinkling can be performed depending on the material. Specifically, knits such as rayon, tencel, hemp material and woolsata may damage the texture or damage if too much mechanical force is applied, and hats with hard cores lose their shape. Sometimes.

  An object of the present invention is to provide a drum-type washing and drying machine capable of effectively deodorizing even clothing of a delicate composition / material.

In order to achieve the above object, the drum type washing and drying machine of the present invention exhausts the air in the water tank by a blower fan, dehydrates moisture by the evaporator and then heats it by a condenser. Repeatedly blowing air from the back wall of the aquarium into the aquarium, and circulating air passages for drying clothes and the like in the rotating drum accommodated in the aquarium and having many through holes, A mist supply unit, and without rotating the rotary drum, the mist supplied from the mist supply unit wets the clothing and the like in the rotary drum, and then heats and dehumidifies the air in the circulation air passage. A deodorization mode for drying the clothes and the like and draining the dewed water to deodorize. In the deodorization mode, the mist wetting treatment and the drying are alternately repeated at least twice. And, a mist processing time is set to one, characterized in that a longer second time than the first time.

  In such a configuration, the drum-type washing / drying machine has a mist supply unit that supplies wet mist to the circulation fan path, so that the mist processing using the circulation fan path can be performed without the rotation of the rotating drum. It is possible to wet dry clothes and the like in a predetermined state. This wet clothing replaces the water molecules with the odor molecules bound to the fibers, making it easier to separate the odor molecules from the fibers, but that alone is not enough to separate the odor molecules and still stays around the fibers. Deodorization is not complete. This enhances the separation of water molecules with odorous molecules by increasing the environmental temperature due to the blowing of heated air in the drying performed after the mist treatment, and at the same time increases the separation of the odorous molecules from the fibers, while separating from the fibers, Further, since the odor molecules that are easily separated are carried on the flow of the exhaust gas to the outside of the water tank, the odor molecules adhering to clothes and the like can be effectively removed. Moreover, since the exhaust that removes odorous molecules from clothes and carries them outside the water tank is dehumidified, the moisture in the exhaust is condensed while trapping the odorous molecules and drained into condensed water, and once separated from the clothes etc. It is possible to prevent odor molecules carried by exhaust from being brought into the water tank again and adhering to clothes. In particular, by repeatedly performing such mist processing and drying twice alternately, opportunities for effective separation, carrying, and removal of odor molecules by a combination of mist processing and drying increase.

  In each of the above cases, the deodorization mode may be characterized in that the initial mist treatment is performed for 2 minutes, the initial drying is 15 minutes, the second mist treatment is 3 minutes, and the second drying is performed for 15 minutes.

  With such a configuration, sufficient deodorization can be achieved even in a process in which a maximum amount of clothing of any material and form is accommodated.

  In this case, it is further characterized by comprising an amount detection means for detecting the amount of clothing or the like housed in the rotating drum, and changing the mist processing time and the drying time according to the detected amount. Can do.

  In such a configuration, it is optimal without waste by changing the mist processing time and the drying processing time according to the detected processing target amount with respect to the mist processing time and the drying time set corresponding to the maximum amount. Mist processing and drying can be performed. Thereby, useless time and running cost can be suppressed.

  In addition, the mist treatment may be performed so that a dry rate of 80% or less is not wet with respect to a material having 70% or more cotton.

  In such a configuration, problems due to excessive wetting by clothing, for example, wearing problems due to progress of shrinkage, changes in texture due to cotton weaving, and lack of color (color transfer) such as clothing with low dyeing fastness Various problems can be prevented from occurring.

  According to one aspect of the present invention, the drum-type washing / drying machine has a mist supply unit that supplies mist to the circulation air flow path, so that the rotation drum is not rotated. Put the dried clothes, etc. in the wet state to the prescribed wet state by mist treatment, and at least replace the odor molecules bound to the fibers with water molecules to facilitate separation of the odor molecules from the fibers, then dry and heat Along with vigorous replacement of water molecules with odorous molecules by blowing air, the odorous molecules separated from the fibers are easily removed along with the exhaust to the outside of the water tank, and moisture is removed during dehumidification. By condensing the odorous molecules while condensing and draining them as dew condensation water, it is possible to prevent the odorous molecules from adhering again to the clothes in the water tank, and a high deodorizing effect can be obtained. Therefore, it is effective when only deodorizing clothes and the like that do not need to be washed and is suitable for forms and materials that are easily damaged by the rotation of the rotating drum. In particular, by repeating the mist treatment and the drying twice alternately, the opportunity for effective separation, carrying and removal of odor molecules by the combination of the mist treatment and the drying is increased, and the deodorizing effect is improved. Further increase.

The technical scope of the present invention is shown not by the content disclosed in the embodiment but by the description of the scope of claims, and further includes all modifications within the meaning and scope equivalent to the scope of claims. Should be understood.

  First, the structure and operation of a drum-type washing and drying machine provided with an atomizing unit according to an embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 is a side cross-sectional view for explaining the structure of a drum-type washing / drying machine according to an embodiment of the present invention, and FIG. 2 shows the arrangement of circulation air flow paths and atomization units of the drum-type washing / drying machine. It is the perspective view seen from the housing | casing back side for demonstrating. FIG. 3 is a cross-sectional view showing a part of the circulating air flow path and the atomizing unit of the drum type washer / dryer as viewed from the rear side of the casing, for explaining the structure. FIG. It is side surface sectional drawing for demonstrating the connection structure of the atomization unit and water tank of a washing-drying machine.

  First, in the drum-type washing / drying machine 1 according to the embodiment of the present invention, a water tank 3 is arranged in a floating state in a washing / drying machine casing 2 by a suspension structure (not shown), and the bottom of the water tank 3 has a bottomed cylindrical shape. The formed rotating drum 4 is disposed with its axial center inclined downward from the front side to the back side. A clothing doorway leading to the opening end of the rotating drum 4 is formed on the front side of the water tank 3, and a door 5 that closes the opening provided on the upward inclined surface formed on the front side of the washing and drying machine housing 2 so as to be openable and closable. The laundry can be taken in and out of the rotary drum 4 through the clothing doorway. Since the door 5 is provided on the upwardly inclined surface, the work for putting in and out the laundry can be performed without bending the waist, and the workability of the drum-type washing machine for taking in and out the laundry from the side opening is generally horizontal. The badness of has been improved.

  As shown in FIGS. 1 and 4, the rotating drum 4 is provided with a plurality of peripheral wall through holes 4c and bottom wall through holes 4f communicating with the water tank 3 on the peripheral wall 4a and the bottom wall 4b. In FIG. 7, bottom surface inlets 4d are formed at a plurality of positions along the circumferential direction facing the hot air supply port 18 formed in the upper part of the rear wall of the water tank 3, As shown in FIG. 8, a plurality of radial ribs 4g are formed, and two circumferential ribs 4h are formed concentrically in the circumferential direction so as to intersect the radial ribs 4g.

  In addition, stirring protrusions 4e are provided at a plurality of positions on the inner surface of the peripheral wall 4a. The rotating drum 4 is rotationally driven in the forward and reverse directions by a motor 6 attached to the back side of the water tank 3. Further, a water supply pipe 7 and a drain pipe 8 are connected to the water tank 3, and water is supplied into the water tank 3 and drained from the water tank 3 by control of a water supply valve and a drain valve (not shown).

  When the door 5 is opened and laundry and detergent (the detergent may be automatically added in the initial stage of water injection) are introduced into the rotating drum 4 from the opening, and the operation of the drum type laundry dryer 1 is started. A predetermined amount of water is poured into the water tank 3 from the water supply pipe 7, and the rotary drum 4 is driven to rotate by the motor 6 to start the washing process. By the rotation of the rotating drum 4, the laundry accommodated in the rotating drum 4 is lifted in the rotating direction by the stirring protrusion 4e provided on the inner peripheral wall of the rotating drum 4, and the stirring is dropped from an appropriate raised height position. Since the operation is repeated, the laundry has the effect of tapping and washing.

  After the required washing time has elapsed, the dirty washing liquid is discharged from the drain pipe 8, and the washing liquid contained in the laundry is dehydrated by a dehydrating operation that rotates the rotating drum 4 at a high speed. Then, water is supplied from the water supply pipe 7 to perform the rinsing / dehydration process. Also in the rinsing / dehydrating step, the laundry accommodated in the rotating drum 4 is repeatedly agitated by being lifted and dropped by the agitating protrusion 4e by the rotation of the rotating drum 4, and rinsed. Then, after rinsing, the water contained in the laundry is dehydrated again by the dehydration operation of rotating the rotating drum 4 at a high speed, and the rinsing / dehydration step is completed.

  The drum-type washing / drying machine 1 has a function of drying laundry stored in the rotating drum 4. The air in the water tank 3 is exhausted to dehumidify, and the heated dry air is blown into the water tank 3 again. A circulating air passage 9 is provided. In the middle of the circulation air passage 9, dehumidifying means such as the evaporator 10, heating means such as the condenser 11, and air blowing means such as the air blowing fan 12 are provided at a lower position in the washing and drying machine housing 2. Yes. The circulation air passage 9 is composed of a circulation air introduction line 13 between the water tank 3 for exhausting from the water tank and the blower fan 12, and a dry air blower line 14 between the blower fan 12 and the water tank 3. The atomizing unit 30 is connected to an upper position near the hot air supply port 18 formed on the back wall of the water tank 3 in the dry air blowing duct 14.

  The dry air blowing duct 14 is configured with a lower duct 15, a flexible duct 16, and an upper duct 17 in order from the upstream side in the space behind the washing / drying machine casing 2 (the back side of the water tank 3). A communication port 17 a is opened below the downstream end of the upper pipe line 17, and the communication port 17 a is connected to a hot air supply port 18 provided on the back surface of the water tank 3. The upper pipe line 17 is inclined to rise toward the center of the housing 2 at the lower part thereof, bent about 90 ° in the middle, and directed toward the hot air supply port 18 of the water tank 3 at the upper part thereof. Inclined downward. The flexible duct 16 is configured by using a flexible pipe material, and prevents the vibration of the lower pipe line 15 accompanying the rotation of the rotary drum 4 or the start / stop from being transmitted to the blower fan 12 side. . The dry air dehumidified by the evaporator 10 and heated by the condenser 11 is sent from the hot air supply port 18 to the water tank 3 and the rotary drum 4 located in the interior thereof via the dry air blowing pipe 14. It is.

  By rotating and driving the blower fan 12 at high speed, an air flow is generated in the circulation blower passage 9, and the humid air in the rotary drum 4 containing the laundry passes through the through holes 4c provided in the peripheral wall 4a. The air is exhausted from the water tank 3 to the circulating air introduction pipe 13 to the blower fan 12 side, dehumidified by dew condensation by the evaporator 10 located upstream of the blower fan 12, and heated by heat exchange with the condenser 11. As a result, high-temperature dry air is obtained.

  The heated dry air is sent from the blower fan 12 to the dry air blower duct 14 to the water tank 3 and is sent into the water tank 3 through the hot air supply port 18 provided in the water tank 3. The high-temperature dry air sent into the water tank 3 is introduced into the rotating drum 4 through a bottom opening 4d and a through hole 4c provided in the bottom wall 4b of the rotating drum 4, and flows between laundry such as clothes. While being dried, it becomes moist air, passes through the through holes 4c provided in the peripheral wall 4a to the water tank 3, and is again introduced into the circulating air introduction conduit 13. A drying process is implemented by the circulation of the air in such a circulation ventilation path 9 (circulation air introduction pipe line 13, dry air ventilation pipe line 14).

  Here, the drum-type washing / drying machine 1 according to the present embodiment has an “wrinkle” for the purpose of spreading and reducing wrinkles of dry clothing while rotating the atomizing unit 30 and the rotating drum 4 described later. "Nobashi Course" is provided. In this “wrinkle spreading course”, the evaporator 10 and the condenser 11 are stopped, the rotational speed of the rotary drum 4 and the blower fan 12 is rotated at a lower speed than in the normal drying process, and the atomization unit 30 is activated. As a result, the mist 20 made of fine droplets is generated in the atomizing unit 30 and the mist 20 is dropped into the dry air flow flowing through the dry air blowing duct 14. In a state where a lot of fine wet mist and dry mist are present, it is fed into the water tank 3 and introduced into the rotating drum 4. In this way, a process is performed in which the mist 20 is filled to every corner in the rotating drum 4 to effectively moisten the clothing surface and to reduce the wrinkles of the clothing in a dry state. Is done. Further, after that, the atomization unit 30 is stopped, the rotational speeds of the rotary drum 4 and the blower fan 12 are increased to the same speed as the normal drying process, and the evaporator 10 and the condenser 11 are operated, A drying operation can be performed to stretch the wrinkles of the clothing while drying the clothing. In the “wrinkle spreading course” described above, the rotating drum 4 does not necessarily have to be rotated.

  Further, in the above-described “wrinkle spreading course”, it is possible to reduce wrinkles with the mist 20 as described above, and further, a deodorizing effect can be expected by the following principle. Usually, the odor is attached to the clothing surface as a odor component as a molecule. For example, the smell of tobacco and grilled meat is the same, but the water molecules in the mist replace the binding between the odorous molecules and the fibers and are detached from the clothing. Then, after such a mist treatment, a drying operation is performed to evaporate the water in which the odor component is dissolved by high-temperature and low-humidity air, and carry out the odor molecule on the flow of the exhaust gas outside the water tank. It becomes possible.

  Here, the wrinkle spreading mechanism of cellulosic fibers such as cotton and hemp will be explained. The wrinkles formed in clothing are usually stable by hydrogen bonding between the fibers and restraining each other as shown in FIG. It has become. Therefore, when the clothing fibers are uniformly moistened, the hydrogen bonds between the fibers disappear as shown in FIG. 13B, and the fibers can move freely. In this state, the rotating drum 4 is rotated, lifted, dropped and struck repeatedly to stretch the fibers as shown in FIG. As shown in FIG. 13 (d), the fibers stretched by drying after wrinkling are fixed again in the stretched state by hydrogen bonding, and the garment is stabilized in the stretched state.

  Moreover, the deodorizing mechanism by a mist process is demonstrated. The odor is attached to the clothing by binding the odor molecule to the fiber as shown in FIG. In addition, when the fiber is evenly wetted with mist, the water molecules forming the mist particles without increasing the drying load in the case of being wetted with water, as shown in FIG. Replace the bond with water molecules, break the bond of odor molecules and make it easier to leave the fiber. Therefore, when the air is blown, the odorous molecules that are easily separated from the fibers can be carried away from the clothing as shown in FIG.

  Therefore, in the drum-type washing / drying machine 1 of the present embodiment, wrinkles can be spread and deodorized by drying after the mist treatment. Moreover, the humid air carrying odorous molecules exhausted through the water tank 3 and the rotating drum 4 in the drying process is condensed by the evaporator 10 as condensed water, and this condensed water has been carried from the clothing. Since the odor molecules are captured and drained together with the dew condensation water, the odor molecules once separated from the clothing and carried by the circulating air do not circulate and adhere to the clothing.

  Next, the configuration of the atomizing unit 30 and the “wrinkle spreading course” according to the present invention will be described in detail with reference to FIGS. 5 and 6 and the above-mentioned drawings. FIG. 5 is a side sectional view for explaining the structure of the atomizing unit of the drum type washing / drying machine 1 according to the embodiment of the present invention, and FIG. 6 is a rear sectional view thereof.

  The atomization unit 30 is disposed at an upper position close to the hot air supply port 18, and includes a water storage container 31 that stores water 21 as a mist generation source, and water 21 stored in the water storage container 31. On the other hand, an ultrasonic transducer 32 for applying ultrasonic vibration, a water injection device 33 for injecting water 21 into the water storage container 31, and a water temperature sensor 35 for measuring the water temperature in the water storage container 31 are provided. Yes. And the water storage container 31 of the atomization unit 30 is arrange | positioned in the upper position adjacent to the warm air supply port 18 in the back surface of the water tank 3, and it dries directly via the connection port 31e located above the warm air supply port 18. It is connected to the upper duct 17 of the air blowing duct 14 (circulation ventilation path 9).

  The water storage container 31 is fixed adjacent to the outer rear surface of the water tank 3, and the front side wall 31 b facing the water tank 3 of the water storage container 31 is inclined with respect to the vertical direction along the rear surface of the water tank 3. The rear side wall 31b is formed in the vertical direction along the back panel of the washer-dryer casing 2, and the bottom wall 31a side of the water reservoir 31 is formed wide.

  The water storage container 31 stores water 21 as a mist generation source, and a water injection port 31c for injecting the water 21 from the water injection device 33 is provided at the upper portion thereof, on the side facing the upper pipe line 17. An opening weir 31d is provided in the side wall 31b, and thereby, a connection port 31e connected to the upper pipe line 17 is provided in an upper portion of the hot air supply port 18. By allowing the water 21 injected into the water storage container 31 from the water injection port 31c to overflow from the opening weir 31d to the upper conduit 17 above the hot air supply port 18 through the connection port 31e, the water can be stored with a simple configuration. The water 21 in the container 31 is configured to be kept at a constant water level. The water 21 overflowing from the opening weir 31d is supplied to the water tank 3 through the connection port 31e, the upper pipe line 17 and the hot air supply port 18, and is discharged to the outside through the drain pipe line 8. The

  The ultrasonic transducer 32 is disposed with the vibration surface 32a of the piezoelectric element that generates ultrasonic vibrations in close contact with the bottom wall 31a of the water storage container 31, and by operating the piezoelectric element, the ultrasonic transmission direction 32b. The ultrasonic vibration is transmitted in the direction (perpendicular to the vibration surface 32 a), and the liquid column 22 is formed in the water 21 in the water storage container 31. As shown in FIG. 6, since the ultrasonic transducer 32 is attached so that the vibration surface 32a faces the opposite side of the connection port 31e, the liquid column 22 is opposite to the connection port 31e. It is formed toward the inner surface of the side wall 32b. As the liquid column 22 is formed, the water 21 in the water storage container 31 rises along the liquid column 22 and descends and rises along the inner surface of the side wall 31b as indicated by the arrows. Occurs. At the same time, the ultrasonic vibration transmitted through the liquid column 22 finely vibrates the surface of the water 21, thereby weakening the surface tension near the tip of the liquid column 22 and responding to the fine vibration of the liquid column 22. Mist 20 (mist) which is a fine droplet is generated, and this mist 20 is pushed out by the convection motion of the water 21 described above and discharged toward the ultrasonic wave transmitting direction 32b. It descends and rises along the inner surface of the side wall 31b according to the convection, and is then discharged along the surface of the stored water 21 and the inner surface of the side wall 31b through the connection port 31e to the upper pipe line 17 above the hot air supply port 18. . The mist 20 discharged to the upper pipe line 17 is sent to the water tank 3 from the hot air supply port 18 immediately below, and further, the rotating drum 4 is connected to the rotating drum 4 through the bottom opening 4d and the bottom wall through hole 4f. Introduced in.

Further, in the present embodiment, when the mist 20 is introduced into the rotating drum 4, the blower fan 12 is rotated at a rotational speed of about 500 rpm. At this time, the amount of air flow in the circulating air flow path 9 is 0.07 m ³ / min, and during the rated operation in the normal drying process (the air blowing fan 12 is rotated at a constant speed of 5800 rpm, and the dry air air blowing line against 2.2 m ³ / min flow rate of the dry air is sent in) to 14, about 1/10 the rotational speed of the rotating fan corresponds to about 1/30 in the blast volume. By causing air to flow through the dry air blowing duct 14 with such a weak air volume, wind pressure that pushes the mist 20 into the rotating drum 4 from the hot air supply port 18 acts and appropriately introduces it into the rotating drum 4. In addition, wet mist and highly dry dry mist can be simultaneously introduced into the rotary drum 4 from the hot air supply port 18, the temperature of the clothing is close to room temperature, and the temperature of the mist 20 is When it is high, moisture is condensed on the surface of the clothes, and the clothes can be moistened more efficiently.

The blowing rate of air flow in the circulating air passage 9 to obtain such an ^effect, 0.05m ^{3 /min~1.00m} 3 / min are suitable, this air volume is 0.05 m ³ / If it is less than min, when the wet mist is introduced into the rotating drum 4, the clothes in the rotating drum 4 become an obstacle and cannot sufficiently enter the rotating drum 4. It may flow down between the rotary drum 4 and the amount of dry mist introduced into the rotary drum 4 is reduced, so that the above effect cannot be obtained sufficiently. Further, when the air flow rate in the circulating air flow path 9 exceeds 1.00 m ³ / min, the wet mist collides with the tube wall of the dry air air flow line 14 (upper line 17) and the wet mist The existence ratio is reduced, and the dry mist passes through the rotary drum 4 without adhering to the clothing.

  Further, in the present embodiment, as shown in FIGS. 3 and 6, rectifying fins 36 (rectifying means) are provided in the vicinity of the upper portion of the connection port 31e connected to the dry air blowing conduit 14 of the water storage container 31. Yes. The rectifying fins 36 are configured by a plate-like member that horizontally crosses the dry air blowing duct 14 at a position that enters the dry air blowing duct 14 side from the connection port 31e. As described above, when the blower fan 12 is rotationally driven in the “wrinkle spreading course”, an air flow is generated in the dry air blower duct 14, but in the case where the rectifying fin 36 is not provided, However, by providing the rectifying fins 36, a part of the air flows through the rectifying fins 36 as shown by the broken arrows. It branches by passing through the upper part, is introduced into the atomization unit 30 from the upper part of the connection port 31e, and then circulates in the atomization unit 30 and again passes from the connection port 31e to the dry air blowing conduit 14. A return air flow will be formed. In such a state, the mist 20 generated in the atomization unit 30 rides on the air flow described above and flows into the dry air blowing duct 14, and further, due to its own weight and air flow, the hot air supply port 18. And is introduced into the water tank 3 and further into the rotating drum 4.

  Since the liquid column 22 is formed to be inclined toward the inner surface of the side wall opposite to the connection port as described above, the water 21 is spilled into the upper pipe line directly through the connection port by the liquid column 22. Therefore, it is possible to prevent an excessive decrease in the water 21 in the water storage container 31.

  The water injection device 33 is for replenishing the water 21 consumed by the generation of the mist 20 in the water storage container 31. The water supply port 33 a provided below the water injection device 33 and the water injection port 31 c of the water storage container 31 are provided. Are connected by a water injection hose 34, and an on-off valve (not shown) is provided at an appropriate position therebetween. In the first stage when the atomizing unit 30 is activated, the water injection device 33 opens the on-off valve and supplies water from the water supply port 33a of the water injection device 33 for a predetermined time sufficient for water to accumulate in the water storage container 31. While supplying the water 21 through the hose 34, the excess water 21 is overflowed from the opening weir 31d of the side wall 31b, and the water 21 in the water storage container 31 is kept at a constant water level. The water injection operation at the initial stage of the start-up is for replenishing the water 21 in the water storage container 31 that has decreased due to evaporation or the like during the pause and always operating the atomization unit 30 under a constant water level.

  The water temperature sensor 35 is configured using a thermistor or the like, and measures the water temperature in the water storage container 31. When the water temperature measured by the water temperature sensor 35 exceeds a predetermined temperature (set to the upper limit temperature of use of the ultrasonic transducer 32 or a temperature slightly lower than that), the water 21 is supplied from the water injection device 33 and the water temperature is adjusted. The water temperature in the water storage container 31 is always kept from exceeding the predetermined temperature.

  The mist 20 generated by the atomizing unit 30 differs in characteristics such as buoyancy and surface tension (wetting) depending on the particle size. That is, an ultrafine mist having a particle size of less than 10 μm is also called a dry mist and is extremely fine, and thus has a high surface tension and high floating property, but has low wettability when attached to an object. ing. Fine mist having a particle size of 10 to 50 μm is also called wet mist, and has a relatively large particle size compared to the dry mist described above, and thus has a low surface tension and high wettability when attached to an object. have. A relatively coarse mist having a particle size of more than 50 μm has properties close to water droplets.

  The mist 20 generated in the atomization unit 30 collides with the side wall 31b of the water storage container 31 and the pipe wall of the upper pipe line 17 while moving to the warm air supply port 18, or aggregates with each other. As a result, the coarse mist gradually drops and separates, and the fine wet mist increases its abundance ratio. And it introduce | transduces in the rotating drum 4 in the state which has wet mist as a main body.

Here, the mist 20 in a state mainly composed of wet mist is a state in which the wet mist exceeds 50% of the entire volume abundance ratio, and the particle size distribution of the mist 20 is measured by a measuring apparatus using a laser diffraction scattering method. It means a state where the average particle diameter (median diameter D ₅₀ ) is in the range of 10 to ₅₀ μm.

  If the path during which the mist 20 moves to the hot air supply port 18 is long, or if there is a bent part in the path, even the fine wet mist aggregates and falls off, and the wet mist in the mist 20 is separated. Since the existence ratio decreases and the mist 20 is mainly dry mist, it is not desirable. According to the configuration described above, the mist 20 generated in the atomization unit 30 includes the atomization unit 30 (water storage container 31) located above the hot air supply port 18 and the dry air blowing duct 14 (upper duct 17). From the connection port 31e to the dry air blowing duct 14, it is dropped by its own weight, dropped from the hot air supply port 18 into the water tank 3 with wet mist as a main component, and further into the rotating drum 4 be introduced. Moreover, since the blower fan 12 is disposed at a lower position in the washing / drying machine housing 2 and the dry air is sent from the blower fan 12 to the dry air blower duct 14, the atomization unit 30 into which the mist 20 is introduced. In the connection port 31e, the mist 20 is introduced into the dry air flow without being affected by the wind pressure (dynamic pressure) from the blower fan 12.

  Thus, since the movement path from the atomization unit 30 to the hot air supply port 18 is short and is configured to fall by its own weight, it suppresses aggregation of wet mist in the middle of the movement path, and wettability. The mist 20 can be introduced and filled in the rotating drum 4 in a state mainly composed of a wet mist having a particle diameter of 10 to 50 μm, and the surface of the clothes can be effectively moistened. By drying the clothes in a state, wrinkles that have entered the clothes can be effectively reduced.

  Further, in the “wrinkle spreading course”, the effect of reducing the wrinkle of clothing can be obtained without necessarily rotating the rotating drum 4. However, as described above, the rotating drum 4 is rotated. While the clothes in the rotating drum 4 are in a dry state at room temperature, the water temperature in the water storage container 31 rises due to the oscillation of the ultrasonic vibrator 32, so that the generated mist 20 is compared with the clothes surface temperature. And it becomes a high temperature. Accordingly, since the dry mist can also be introduced into the rotating drum 4 at a high temperature, not only the wet mist but also the dry mist has a surface of clothing that is lower than the temperature of the mist and the peripheral wall of the rotating drum 4. 4a or the like is easily condensed and condensed as fine water droplets. At this time, by rotating the rotating drum 4, the clothes are stirred, and the mist 20 including the dry mist is not disturbed by the clothes, and the inside of the rotating drum 4 And the entire garment can be moistened more efficiently.

  In the present embodiment, the mist 20 is sent from the connection port 31e to the dry air blowing conduit 14, dropped by its own weight, put on the air flow, and from the hot air supply port 18 into the water tank 3 and further into the rotating drum 4. In addition to the introduction, when the mist is introduced (when the atomization unit is activated), the rotating drum 4 is gently rotated at a rotation speed of about 45 rpm at which the clothes are stirred. In this way, by rotating the rotating drum 4 gently, wet mist that tends to stay near the bottom in the rotating drum 4 can be filled to every corner in the rotating drum 4. Can be effectively moistened with wet mist having high wettability. And the wrinkles which entered clothing can be effectively reduced by drying the clothing of such a state.

  According to the detailed examination of the present inventors, when the laundry is moistened, it is uniformly moistened at a drying rate of 90 to 96% (ideally 95%), and when dried, the drying rate is 99% or more. It has been found that drying is important. Here, the drying rate is a value obtained by multiplying a value obtained by dividing the weight of the laundry in a state before washing by the weight of the laundry after being moistened by 100 and expressed in%.

  In order to fill the wet mist as described above to every corner of the rotating drum 4, the rotating speed when the rotating drum 4 is rotated gently is suitably 15 to 80 rpm, and this rotating speed is less than 15 rpm. When a part of the mist 20 introduced from the hot air supply port stays in the vicinity of the bottom of the rotating drum 4 and the rotational speed exceeds 80 rpm, a part of the mist 20 is subjected to centrifugal force and the side wall of the rotating drum 4. It is pushed toward the side and collides with the side wall or the like, thereby reducing the presence ratio of the wet mist.

  The amount of mist generated per hour of the ultrasonic vibrator 32 used in the present embodiment is the water temperature of the water 21 in the water storage container 31 and the input voltage to the oscillation circuit unit 37 that drives the ultrasonic vibrator 32. Increase or decrease due to changes.

  For example, when the ultrasonic transducer 32 that oscillates at 1.6 MHz is used, if other conditions are fixed and only the water temperature is changed from 5 ° C. to 30 ° C., the amount of mist generated is about 1.5 times. Further, if only the voltage input to the oscillation circuit is changed from 95V to 107V, the amount of mist generated is also about 1.5 times here.

  Normally, the water temperature change and voltage change described above are normal changes that occur at home, so even if the amount of mist generated is at a minimum, the drying rate of clothing that is optimal for spreading wrinkles will be 90% to 96%. When the adjustment is made, the mist generation amount becomes excessive under the maximum mist generation amount condition, and the garment gets wet up to a dry rate of nearly 70% and becomes non-uniform.

  Conversely, if the mist generation rate is adjusted so that the drying rate of the garment is 90% to 96% under the maximum mist generation rate, the garment will hardly damp and remain at around 99% under the minimum condition. The effect is not obtained.

  Therefore, in order to effectively process clothing, it is desirable to keep the water temperature constant and the input voltage constant, but water temperature measuring means, water temperature adjusting means, input power measuring means, and input voltage adjusting means are required.

  In the present embodiment, the mist processing result is stabilized from 90% to 96% without using complicated water temperature adjusting means and input voltage adjusting means.

  The output of the oscillating circuit and the atomizing ability of the ultrasonic vibrator 32 are determined so that the mist processing result is from 90% to 96% under the conditions of the low water temperature and the low input voltage with the least amount of mist generated. .

  If mist is generated under the conditions of high water temperature and high input voltage at which the amount of mist generated is the largest in this atomization capability, as described above, excessive mist is supplied to the clothing.

  This excess mist is trapped in the bottom wall through hole 4f of the rotating drum bottom wall 4b, and the excess mist is collected. At this time, from the relationship between the contact efficiency between the bottom wall through-hole 4f and the mist, the amount of mist trapped naturally is determined according to the amount of mist, and when the amount of mist is small, the contact efficiency is low, so the trap is almost trapped. However, if the amount of mist is excessive, the contact efficiency is increased, so that much mist is trapped.

  Furthermore, in order to prevent moisture generated by collecting surplus mist from entering the rotating drum 4 and coming into contact with the clothes lifted by the rotation, excessive and uneven wetting of the clothes is trapped and collected. Water flows along the radial ribs 4g installed on the back surface of the rotating drum bottom wall 4b by using gravity or centrifugal force, and further intersects with the radial ribs 4g in the previous period and has a dimension higher than that of the radial ribs 4g. Using the circumferential rib 4h installed on the back surface of the rotating drum bottom wall 4b so as to protrude into the water tank 3, the collected moisture is discharged by dropping from the edge of the circumferential rib 4h to the water tank 3 side. The water dropped to the water tank 3 is drained from the water tank 3 by controlling a drain valve (not shown).

  In this way, even if the amount of mist generated by the ultrasonic transducer 32 changes due to the change in the water temperature and the change in the input voltage, the amount of mist supplied into the rotary drum 4 is kept constant. The mist treatment result can be stabilized within the range of 90% to 96% of the drying rate and can be effectively moistened. And by drying the clothing in such a state, wrinkles that have entered the clothing can be effectively reduced and deodorized.

  In the above description, the radial ribs 4g and the circumferential ribs 4h having a dimension higher than the radial ribs 4g and projecting toward the water tank 3 are configured on the back surface of the rotating drum bottom wall 4b. As shown in a) and (b), only the vicinity of the portion where the circumferential rib intersects with the radial rib may have a size higher than that of the radial rib, and the other portion may have a size lower than that of the radial rib.

  As a result, clothing is stuck to the rotating drum bottom wall 4b facing the front of the hot air supply port 18, and the flow of wind flows from the hot air supply port 18 to the water tank 3, the bottom opening 4d, and the rotating drum bottom wall 4b in this order. Even if the circumferential rib 4h has a low dimension, the flow of the wind on the back surface of the rotating drum bottom wall 4b is made free by the portion where the circumferential rib 4h is low, thereby bypassing the portion of the bottom wall 4b covered with clothing. As a result, the flow of wind in the rotating drum is secured, and the air flow in the circulation air passage can be smoothly blown, so that the clothes can be moistened in a shorter time, and also dried in a short time. Therefore, wrinkles of clothing can be reduced in a short time.

  Further, in the above, the radial rib 4g and the circumferential rib 4h are formed on the back surface of the rotating drum bottom wall 4b. However, as shown in FIGS. 11 and 12, a part of the bottom wall 4b is made a separate part. Alternatively, the radial ribs 4g and the circumferential ribs 4h may be formed on the back surface of the bottom wall 4i formed as a separate part. The bottom wall 4i made into a separate part may be fixed to the rotating drum bottom wall 4b by using a hook 4j grown from the separate part bottom wall 4i or a fixing screw boss 4k.

  When the separate part bottom wall 4i is assembled to the rotating drum bottom wall and a gap is formed at the joint, the seal packing 4l may be provided near the outer periphery of the back surface of the separate part bottom wall 4i.

  Thereby, the complicated shape by the radial rib 4g and the circumferential rib 4h formed on the back surface of the separate component bottom wall 4i can be configured as an integrally molded product suitable for mass production.

  In addition, since the bottom wall 4i, which is a separate part, can be assembled later on the rotating drum bottom wall 4b, the assembling process of the rotating drum 4 itself can be simplified.

  In the above embodiment, the example in which the water 21 is used as the mist generation source in the atomization unit 30 has been described. However, an Ag ion electrolytic solution, a detergent solution, a deodorizing solution, and a sterilizing solution are used depending on the application. Etc. may be used, and an effect corresponding to each liquid agent (mist generation source) can be obtained.

  In the present embodiment, in particular, the relationship between the mist and the wetting of the fiber, the relationship between the wetting of the fiber and the wrinkle spreading effect and the deodorizing effect, the behavior of the odor molecule, etc. % Or cotton poly blended material (over 70% cotton) garments and delicate items including delicate clothes can be stably and effectively deodorized and washed alone in a drum-type washer / dryer A deodorizing mode or a wrinkle spreading / deodorizing mode that is effective even if it is adopted as a course menu is executed.

"Deodorization mode"
First, the deodorization mode will be described. In the drum-type washing and drying machine 1 described above, the air in the water tank 3 is exhausted by the blower fan 12 and dehumidified with drainage of condensed water by the evaporator 10, and then the condenser 11. A circulation air passage 9 for drying the clothes in the rotary drum 4 accommodated in the water tank 3 and having a plurality of peripheral wall through holes 4c, bottom wall through holes 4f, etc. The mist 20 supplied from the atomizing unit 30 is wetted with the mist 20 supplied from the atomizing unit 30 without rotating the rotating drum 4 using the atomizing unit 30 provided on the air blowing side of the circulation air passage 9. After that, a deodorization mode is provided in which clothes and the like are dried by heated air to deodorize. In the deodorization mode, mist treatment and drying are alternately performed twice.

  As described above, the drum type washing / drying machine 1 has the atomizing unit 30 for supplying the mist to the circulation air passage 9, so that the mist using the circulation air passage 9 without rotating the rotating drum 4 is used. Clothes etc. dried by the treatment can be wetted in a predetermined state. This wet clothing replaces the water molecules with the odor molecules bound to the fibers, making it easier to separate the odor molecules from the fibers, but that is not enough to separate the odor molecules and still stays around the fibers. Deodorization is not complete.

  This enhances the separation of the odorous molecules from the fibers by vigorous replacement of the odorous molecules with the increase in the environmental temperature due to the blowing of heated air in the drying performed after the mist treatment, and simultaneously molecules from the fibers, Further, since the odor molecules that are easily separated are carried on the flow of the exhaust gas to the outside of the water tank, the odor molecules adhering to clothes and the like can be effectively removed. In addition, since the exhaust gas that removes odorous molecules from clothes and carries them outside the water tank 3 is dehumidified, the moisture in the exhaust gas is condensed while capturing the odorous molecules and drained as dew condensation water, and once separated from the clothes etc., the water tank 3 It is possible to prevent the odorous molecules carried by the exhaust air from being brought back into the water tank 3 and adhering to clothes or the like.

  In particular, by repeating the mist treatment and the drying twice alternately, the opportunity for effective separation, carrying and removal of odor molecules by the combination of the mist treatment and the drying is increased, and the deodorizing effect is improved. Further increase.

  As a result, the drum-type washing / drying machine 1 has the atomizing unit 30 that supplies the mist to the circulation air passage 9, and the rotating drum 4 is in a low power consumption state without the rotation of the rotating drum 4. Dry garments and the like contained in the container in a predetermined wet state by mist treatment, and at least replace the odor molecules bound to the fibers with water molecules to facilitate separation of the odor molecules from the fibers, and then dry In addition to vigorous replacement of water molecules with odorous molecules by the blowing of heated air, the odorous molecules that are molecularly separated from the fibers and easily separated are carried away with the exhaust to the outside of the water tank 4 and removed. When dehumidifying, moisture is condensed while trapping odorous molecules and drained as condensed water, so that odorous molecules can be prevented from adhering again to clothes or the like housed in the rotating drum 4 in the water tank 3, so Odor effect Obtained. Therefore, it is effective when it is desired to remove the smell of cigarettes and grilled meat that are not contaminated and does not need to be washed, and is suitable for forms and materials that are easily damaged by the rotation of the rotating drum. Specifically, knitwear including blended products such as wool setters, embroidery, lace, clothing with hard accessories, rayon, tencel, hemp and blended products, pleats, wrinkles, embossed, etc. Examples include stuffed toys, cushions, jackets, ties, dresses, hats with hard cores, items that easily lose their shape, fabrics that use strong twisted yarn such as crimped noodles, items that cannot be washed, and cannot be dried.

"Wrinkle spreading and deodorizing mode"
Next, the wrinkle spreading / deodorizing mode will be described. In the drum type washing and drying machine 1 of the present embodiment, the air in the water tank 3 is exhausted by the blower fan 12, dehumidified by the evaporator 10 along with the drainage of condensed water, and then heated by the condenser 11. The circulation air passage 9 for repeatedly drying the air and drying clothes or the like in the rotary drum 4 accommodated in the water tank 3 and having a large number of peripheral wall through holes 4c, bottom wall through holes 4f, etc. Using the atomizing unit 30 provided on the side, the clothes in the rotating drum 34 are wetted by the mist supplied from the atomizing unit 30 without the rotation of the rotating drum 4, and then the clothes etc. by the heated air The deodorizing mode in which the odor is removed by drying and the clothes in the rotating drum 4 are wetted by the mist supplied from the atomizing unit 30 with or without the rotation of the rotating drum 4, and then the rotating drum 4 With rotation Wrinkle spreading and deodorizing mode for drying clothes and the like by drying the clothes with hot air is provided as a course menu that is individually selected and executed independently. In the deodorizing mode, the mist treatment and drying are performed. Alternately do it twice.

  Thereby, the deodorizing mode and the wrinkle spreading / deodorizing mode can be individually selected as the course menu and executed independently. Although the deodorizing mode has been described, in the wrinkle spreading / deodorizing mode, the mist and clothing, etc., are provided with appropriate rotation of the rotating drum 4 to the extent that centrifugal force is not applied to the mist supplied in the mist processing. The contact frequency increases and effective and uniform wetting on clothes and the like can be achieved. In particular, in addition to the deodorizing effect similar to that in the deodorizing mode, by rotating the rotating drum 4 during drying, the clothes and the like are repeatedly lifted and dropped by their own weight, and hydrogen bonding between fibers is caused by mist treatment. Wrinkles can be stretched by the mechanical action of lifting, dropping and hitting clothes that have been dissociated, and can prevent wrinkles from being placed, and by drying, the fibers can be hydrogen bonded to stabilize the clothes in a wrinkled state. Be made. Also, it can be supple with fiber resuscitation.

  As a result, the deodorizing mode and the wrinkle spreading / deodorizing mode can be individually selected as the course menu and executed independently, and the mist and clothing are appropriately rotated by the rotating drum 4 as necessary in the mist processing. In addition to the effective and uniform wetting on clothes, etc., in the wrinkle spreading / deodorizing mode, in particular, in addition to the deodorizing effect in the deodorizing mode, the rotating drum is rotated during drying, By repeating the mechanical action of lifting clothes that have been dissociated from the hydrogen bonds between fibers by mist treatment and then gently dropping and hitting them, it is possible to effectively spread wrinkles and to prevent the generation of wrinkles, and it has been extended by drying. The fibers can be hydrogen-bonded to stabilize the clothing in a suitable wrinkled state, and the fiber can be supple by reviving. Therefore, it is effective when you want to remove only wrinkles and odors from clothes that are wrinkled or smelled by clothes, but you do not need to wash them. It is suitable for things other than easy forms and materials. Specific examples include vests, skirts, cut-and-sews, polo shirts, baby clothes, and towel products.

  Further, in the mist process, the rotating drum 4 can be alternately rotated at the low speed of about 45 rpm, with the forward direction continuous rotation and the reverse direction continuous rotation with the rotation stopped. Thus, without applying centrifugal force to the mist, the mist that tends to stay in the lower part of the rotating drum 4 is rotated by rotating the mist and the like up and down by repeating the forward continuous rotation and the reverse continuous rotation. It is possible to smoothly introduce the mist supplied to the rotating drum 4 by stopping the rotation between the continuous rotation in the forward direction and the continuous rotation in the reverse direction while realizing the uniform filling of the drum 4. Therefore, it is preferable to start the mist process by stopping the rotating drum 4.

  In addition, the rotation of the rotating drum 4 during drying in the wrinkle spreading / deodorizing mode is continuously performed at a rotation speed that shows the behavior of clothes, etc. lifted by the rotation of the rotating drum 4 falling from the height where the weight of the rotating drum 4 is reduced. Clothing is stuck to the inner surface of the rotating drum 4 by the forward / reverse continuous rotation driving mode in which the rotation is repeated forward and reverse and the centrifugal force generated by the sudden arc rotation of the rotating drum 4 and more than 90 degrees from the lowest position of the rotating drum 4 to 180 degrees. After being lifted to a position below, the sudden movement of the rotary drum 4 causes clothes or the like to be peeled off from the inner surface of the rotary drum 4 due to its inertia and to drop to the side opposite to the lifting side of the lower range of the rotary drum 4, It is also possible to perform a forward / reverse arc rotation drive mode that is repeated alternately forward and backward.

  Thus, the continuous rotation of the rotary drum 4 at a rotational speed at which the clothes, etc., lifted from the rotary drum 4 by the rotation of the rotary drum 4 has fallen from the height where the weight of the rotary drum 4 has fallen is reversed. In addition to the forward / reverse continuous rotation drive mode performed alternately, the execution of the forward / reverse arc rotation drive mode causes clothing or the like to adhere to the inner surface of the rotary drum 4 by centrifugal force due to the sudden arc rotation of the rotary drum 4. After being lifted from the lowermost position to more than 90 degrees and less than 180 degrees, the rotary drum 4 is suddenly braked and peeled off from the inner surface of the rotating drum 4 due to its inertia and opposite to the lifting side of the lower range of the rotating drum 4 The movement of falling to the side can be repeated alternately forward and reverse, so the left and right alternately in the arc rotation drive every time the clothes and the like are switched between the lifting position and the falling position It can be replaced and the lifting action of clothes etc. can be enhanced, the mechanical force can be applied evenly, the wrinkle spreading effect can be enhanced, and it is economically burdened by alternately executing the forward and reverse continuous rotation drive mode with low power consumption. You can prevent it from increasing. The rotation of the rotating drum 4 here is preferably set to around 50 rpm.

  In addition, the mist treatment in the wrinkle spreading / deodorizing mode is performed so that the drying rate is 96% or less with respect to the material having 70% or more of cotton, so that the material fibers are evenly wetted due to the water absorption of these materials. And since it is sufficient, both the deodorizing action and the wrinkle spreading action can be applied to every corner of clothing. It is not necessary to satisfy the above-mentioned wetting conditions with a synthetic fiber material with low water absorption, etc., but since the excess can be skipped by a slight combination of rotation of the rotating drum and air blowing, the wrinkle spreading action in a moist and moist condition In particular, it is not necessary to distinguish the wetting conditions.

  In addition, the mist treatment is carried out so that the dry rate does not get wet to 80% or less with respect to a material having 70% or more of cotton, thereby causing problems due to excessive wetting by clothing, for example, wearing due to progress of shrinkage. It is possible to prevent various problems such as defects, changes in texture due to cotton weaving, etc., and lack of color (color transfer) in clothing with low dyeing fastness.

"Example"
Here, in one embodiment, as shown in FIG. 16, in the deodorization mode, the mist treatment and drying are mist treatment (a) (c) and drying (b) (c). In such a manner, it is repeated alternately at least twice. As a result, opportunities for effective separation, carrying and removal of odor molecules by a combination of mist treatment and drying are increased, and the deodorizing effect is further enhanced. Specifically, the drying of (b) after the mist processing mist in (a) increases the temperature of the mist at the time of the previous mist processing and enhances the separation action of the odorous molecules, and the separation of the odorous molecules separated. Carrying out and discharging by dehumidification is performed, and the mist supplied at the time of the mist treatment in (c) is made hot mist due to the drying effect in (b), and the action of separating odor molecules is enhanced, and the drying in (d) In some cases, the mist molecules are further heated to further increase the separation effect of the odor molecules, and at the same time, the separated odor molecules are carried and discharged by dehumidification. Also, the deodorization mode shown in FIG. 16 is (a) 2 minutes for the first mist treatment, 15 minutes for the first drying in (b), 3 minutes for the second mist treatment in (c), (d) The second drying was performed for 15 minutes, and sufficient deodorization was achieved with the maximum amount irrespective of the difference in the material to be treated, and a favorable result was obtained.
