  With such a clothing drying device, airflow can be intermittently applied to the clothing on the end side that is most difficult to dry against clothing that has been dried in large quantities in a wide range, but it cannot continue to apply airflow continuously and widely. There was a problem that the drying time was long.

  Also, if you want to dry a small amount or thick clothing such as a piece of jeans in a short time, a wide air blowing range not only wastes wasted energy, but also the drying time is long because the wind speed of the airflow against the clothing is slow. There was a problem of becoming.

By rotating the wind direction changing plate fixed in a substantially C shape 180 degrees around the rotation axis, the airflow flowing in the air passage is reduced more than the opening width of the air outlet. It has the effect | action that it can blow.

  Also, when the air flow sent from the air blowing means flows in the air passage of the main body, the wind speed of the air current near the center of the air passage is fast due to friction with the air passage wall, and the air speed of the air flow decreases as it approaches the air passage wall.

The wind direction changing plate located near the center of the outlet is used as the center plate. When the two wind direction changing plates located at the outermost end of the outlet are end plates and the wind direction changing plate located between the center and the outermost end of the outlet is an intermediate plate, the central plate is more than the intermediate plate. Is longer, and the wind direction of the airflow is diffused or concentrated in the direction of the axis of the rotation axis by rotating the rotation axis by 180 °, and the wind path is fixed by fixing the wind direction change plate in a substantially square shape. The airflow flowing inside can be blown larger than the opening width of the air outlet, and the wind direction change plate fixed in a substantially C-shape is rotated 180 ° around the rotation axis, so that the inside of the air passage is It has the effect | action that it can reduce and flow the flowing airflow from the opening width of a blower outlet.

  Also, when the air flow sent from the air blowing means flows in the air passage of the main body, the wind speed of the air current near the center of the air passage is fast due to friction with the air passage wall, and the air speed of the air flow decreases as it approaches the air passage wall. There is a tendency. Therefore, by setting the center plate longer than the intermediate plate, increasing the friction between the airflow near the center of the flap and the center plate and increasing the pressure loss near the center of the flap to some extent, the flap end side It is possible to increase the air volume of the air flow that is guided to the air flow, to make the air speed of the air flow sent from the blowing means uniform, and to blow a wide range of air.

  In the clothes drying apparatus according to claim 5 of the present invention, a constant distance is provided between the end of the flap or the guide wing and the end of the center plate and the intermediate plate. By setting the position of from the middle of the flap or the guide wing, the airflow sent by the blowing means can be guided to the flap or the guide wing while reducing the pressure loss.

  In the clothes drying apparatus according to claim 6 of the present invention, the end portion of the flap and the end portion of the end plate coincide with each other, and the portion surrounded by the surface that does not contact the airflow of the end plate and the flap is sealed. By sealing a portion that does not become a flow path for airflow, the airflow passing through the flap can be prevented from divergence and pressure loss can be reduced.

Yes, by providing the rib on the outside of the wind direction changing plate, the strength of the wind direction changing plate is improved.
It has the action.

  In the clothes drying apparatus according to claim 10 of the present invention, the flap or the guide wing serves as a lid for opening and closing the air outlet, and when the blowing means is stopped, the flap or the guide wing has an opening at the opening. It has the effect of closing the air outlet with a non-surface.

  The clothing drying apparatus according to claim 11 of the present invention has an auxiliary flap around the flap, and the auxiliary flap has an auxiliary flap rotating shaft on one side of the auxiliary flap, and the auxiliary flap is rotated in the rotational direction of the auxiliary flap rotating shaft. And an auxiliary flap holding means for holding the auxiliary flap rotatably on the rotation shaft, and the flap and the auxiliary flap perform the same operation. By providing the auxiliary flap, the airflow controllability by the Counder effect is improved, and the wind speed reaching the clothing can be improved.

  In the garment drying apparatus according to claim 12 of the present invention, the wind direction changing means includes rotation stopping means for fixing the rotation angle of the rotating shaft at a predetermined angle, and the rotation suppressing means temporarily The position where the rotation is suppressed is set as the origin, and the angle of the wind direction changing plate is adjusted with this point as a base point.

  According to a thirteenth aspect of the present invention, there is provided a clothing drying apparatus according to a thirteenth aspect of the present invention, wherein the main body has a control unit that controls the driving means, and the control section reciprocates the wind direction changing means in the rotation direction of the rotary shaft. The greater the rotation angle of the driving means with respect to the flow of the sent airflow, the slower the driving speed of the driving means. When controlling the airflow in the direction of rotation of the rotating shaft by the wind direction changing means, If the wind direction is changed at an angle, the pressure loss in the flap increases, the wind speed decreases, and the clothes present at a position shifted from the outlet become difficult to dry, resulting in drying unevenness. Therefore, when reciprocating the wind direction changing means in the rotation direction of the rotating shaft, the larger the angle with respect to the flow of the air flow sent from the blower means, the slower the driving speed of the driving means, thereby deviating from the outlet. It has the effect | action that the ventilation time with respect to the clothing which exists in a position can be lengthened.

  According to a fourteenth aspect of the present invention, there is provided the clothes drying apparatus according to the present invention, wherein the body is provided with an infrared sensor that detects an object temperature in the blowing direction, and the infrared sensor divides the detectable area of the infrared sensor into predetermined partial areas, The surface temperature of an object existing in a partial area is to be detected, the object temperature before blowing is the reference temperature, and after starting blowing, the surface temperature of the object that is exposed to the wind is measured, and the measured value is higher than the reference temperature. The driving means is controlled so that the lower area is the blowing direction, and when the wind hits the moisture-containing clothing, the temperature of the object surface is lowered by the heat of vaporization. The lowered position is determined to be undried, and the air is concentrated.

  In addition, the clothes drying apparatus according to claim 15 of the present invention, after a lapse of a predetermined time from the start of blowing, when the difference between the reference temperature and the measured value of the infrared sensor is smaller than a preset set value, When the air blower is stopped and the main body is covered with a flap, and the temperature does not decrease after the air blow is started, it can be determined that the evaporation of the water to be blown is completed, so the air blower is stopped. In addition, the main body is covered with the auxiliary wing.

  In the clothes drying apparatus according to claim 16 of the present invention, the main body has a heat source, and after the air blowing direction is determined by the infrared sensor, the heat source is operated. By intensively blowing air to the remaining position, there is an effect that the evaporation of moisture can be promoted.

  According to the seventeenth aspect of the present invention, the wind direction can be changed to the rotational direction by swinging the flap or the guide vanes about the rotational axis, and the swing angle connects the rotational axis and the upper end of the clothing. The airflow blown from the airflow direction changing means becomes a jet in the indoor free space and spreads while entraining the air around the jet, so that the swing angle is larger than the clothing end. Since the garment edge can also be blown by the spread of the jet flow on the inside, there is no waste of blowing air to the area where no garment exists, and there is an effect that the drying time can be shortened with energy saving.

  In the invention according to claim 18 of the present invention, the speed at which the wind direction changing means is swung around the rotation axis is slow when the air measured by the infrared sensor is blown to the low temperature region, and the high temperature region. When the air is blown, the air flow is controlled at a low temperature, that is, a region of clothing that contains moisture, and the air flow is applied to a region of clothing that has a high temperature, ie, does not contain moisture. By shortening the contact time, the entire garment can be efficiently dried, so that the drying time can be shortened with energy saving.

  According to the nineteenth aspect of the present invention, the wind direction changing means is provided when the temperature of the end region of the garment measured by the infrared sensor is higher than a predetermined temperature with respect to the temperature of the central region of the garment. If the temperature of the clothing end region is high and the temperature of the clothing central region is lower than that, the center contains more moisture than the clothing end. Therefore, since the center of the garment can be dried by concentrating the airflow in the center by the wind direction changing means, and the entire garment can be efficiently dried, it has the effect of saving energy and shortening the drying time. * Described in the examples, with the reason that the outside is easier to dry than the center.

  Further, the invention according to claim 20 of the present invention is such that the length of the flap or the guide blade is 1.2 to 1.7 times the length of the air outlet in the rotation axis direction. By increasing the distance, it becomes easier to expand the airflow in the direction of the rotation axis by blowing airflow to a space wider than the opening, so that the entire clothing can be efficiently dried by applying the airflow to the clothing at a uniform wind speed, It has the effect of saving energy and shortening the drying time.

  The invention according to claim 21 of the present invention is such that the length in the airflow direction of the intermediate plate is 0.3 to 0.7 times the length in the airflow direction of the center plate. However, by setting the center plate longer, increasing the friction between the airflow near the center of the flap and the centerplate, and increasing the pressure loss near the center of the flap to some extent, the airflow induced toward the end of the flap The air volume can be increased, and the airflow sent from the blowing means can be uniformly expanded.

  The invention according to claim 22 of the present invention is arranged so that the central plate and the intermediate plate do not overlap when the central plate and the intermediate plate are projected in the airflow direction, and flows between the central plate and the intermediate plate. By securing the space, the pressure loss generated when the airflow flows does not increase, so that the drying time can be shortened with energy saving.

  In the invention according to claim 23 of the present invention, the length in the rotation axis direction of the intermediate plate is 1.2 to 1.6 times the length in the rotation axis direction of the center plate. By increasing the inclination of the intermediate plate located on the end side of the plate, it is easy to diffuse the air current, and by uniforming the wind speed, the entire clothing can be dried efficiently, saving energy and shortening the drying time Has the effect of being able to.

  Further, in the invention according to claim 24 of the present invention, the wind direction changing means is made of moldable resin, and it is not necessary to assemble and manufacture a plurality of parts, and it is difficult to break because it is formed as an integral structure. Has an effect.

  Further, the invention according to claim 25 of the present invention is provided with notifying means for notifying that the clothing drying is finished in the main body, and the user can recognize the timing when the clothing drying is finished. Has an effect.

  According to a twenty-sixth aspect of the present invention, the notifying means is a display lamp that can be visually checked on the external appearance of the main body, and has an effect that the user can recognize the timing when the clothing drying is finished.

  Further, the invention according to claim 27 of the present invention is a notification sound generating means for generating a notification sound as the notification means, and has an effect that the user can recognize the timing when the clothing drying is finished. .

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
First, the configuration of the first embodiment will be described.

  In Embodiment 1, the clothes drying apparatus is a bathroom clothes dryer.

  1 is a sectional view of a main body 1 according to Embodiment 1 of the present invention, and FIG. 2 is an external view of the main body 1 according to Embodiment 1 of the present invention.

  As shown in FIGS. 1 and 2, the main body 1 is embedded in the ceiling 4 at the top of the bathtub 3 in the bathroom 2, and wet clothes are hung directly under the main body 1, and air is blown from the main body 1 to dry the clothes. .

  The main body 1 includes an air blowing means 5 (an example is a fan motor) and a control unit 6 (an example is a circuit on which a microcomputer is mounted), and an air inlet 7 for taking in indoor air upstream of the air blowing means 5 and an air blowing means. An air outlet 8 is provided on the downstream side of 5, and the air inlet 7 and the air outlet 8 are connected by an air passage. Moreover, the main body 1 is configured to include a wind direction changing means 9 in the vicinity of the air outlet 8. Here, the main body 1 has an air blowing means 5 and a wind direction changing means 9 as long as it is intended for drying clothes, and may be a dehumidifier other than a bathroom clothes dryer.

  FIG. 3 is an external view of the wind direction changing means 9 according to the first embodiment of the present invention.

  As shown in FIG. 3, the wind direction changing means 9 includes a rotating shaft 10 that rotatably supports the wind direction changing means 9, a holding portion 11 that rotatably holds the rotating shaft 10 on one of the rotating shafts 10, and a rotation On the other side of the shaft 10, a driving means 12 (stepping motor as an example) for rotating the rotating shaft 10, and an opening that is fixed to the rotating shaft 10 and has a through opening as an air passage, rotate the airflow direction of the airflow from the outlet 8 The flap 13 is configured to be controlled in the rotational direction of the shaft 10, and the wind direction changing plate 14 is disposed so as to be sandwiched between the flaps 13 and is fixed to the flap 13 in a substantially square shape. Of the wind direction changing plates 14, the central two plates located at the center are the central plate 15, the two adjacent to the central plate 15 are the intermediate plates 16, and the two most adjacent plates are the end plates 17. The wind direction changing plate 14 is an integrally molded product.

  Thereby, since it is formed in an integral structure, there is no need for assembly adjustment, and it is difficult to break, so there is an effect that the product life can be extended.

  4A is an external view of the wind direction changing means when the air flow sent from the blowing means 5 is expanded, and FIG. 5 is a wind speed distribution diagram when the length of the wind direction changing plate 14 is the same or the center plate 15 is long. It is.

  As shown in FIG. 4A, the central plate 15 is longer than the intermediate plate 16.

  FIG. 5 shows a wind speed distribution in a section of 100 mm pitch and 400 mm in the parallel direction from the center of the heel at a height 200 mm below the heel where the clothes are suspended. Comparing the wind speed distribution when the length of the intermediate plate 16 and the central plate 15 is the same as that when the central plate 15 is longer than the intermediate plate 16, the longer the central plate 15, the more the wind speed distribution on the edge side of the kite. You can see that it has improved.

Here, the drying rate (q) of clothing is generally represented by the formula (1).
q = α × [(T−T ′) / γ] × A (1)
α: Heat transfer coefficient T: Dry bulb temperature in the bathroom,
T ′: temperature of wet bulb in the bathroom γ: latent heat of vaporization A: coefficient of reduction

  In the formula (1), the heat transfer coefficient (α) is proportional to the wind speed, so the drying speed depends on the wind speed. From this, it can be seen that it is important to uniformly supply air to the clothing in order to shorten the clothing drying time and to prevent uneven clothing drying.

  Therefore, it can be predicted that the result of the wind speed distribution shown in FIG. 5 has the effect of shortening the drying time of the clothes by increasing the length of the central plate 15. Actually, when the drying test of 2 kg of the test cloth was performed according to the BL standard, when the intermediate plate 16 and the central plate 15 have the same length, the drying time is 165 minutes, and the central plate 15 is longer than the intermediate plate 16. In this case, a drying time of 135 minutes was obtained, and the drying time was actually shortened by 30 minutes.

  Thus, according to the clothing drying apparatus of Embodiment 1 of the present invention, the center plate 15 is set longer than the intermediate plate 16, and the friction between the airflow near the center of the flap 13 and the center plate 15 is increased. In addition, by increasing the pressure loss near the center of the flap 13 to some extent, it is possible to increase the amount of airflow that is guided to the end side of the flap 13 and to uniformly expand the airflow sent from the blowing means 5. And drying time of clothes can be shortened.

  At this time, as shown in FIG. 2, the length of the flap 13 is 300 mm, and as shown in FIG. 4, the length between the rotational axis direction of the outlet 8 and the upstream end point of the end plate 17 in the airflow direction. 1 and FIG. 2, the measurement conditions are as follows: the distance from the ceiling 4 to the basket for hanging clothes is 200 mm, and the position where the clothes are suspended from the basket is 200 mm lower (from the ceiling 4). 400mm position), measured at a matrix-like measuring point of ± 50mm horizontally and vertically from the central part of the ridge up to 400mm at a pitch of 100mm from the central part of the ridge, and the wind direction as shown in FIG. The average value which measured the wind speed when changing each ratio in the dimension position which prescribes | regulates the size of the change board 14 is shown to Fig.7 (a)-(c). At this time, the flap 13 or the guide vane 23 is parallel to the airflow direction.

  According to this, as shown in FIG. 6 and FIG. 7A, the overall length W2 of the flap 13 in the rotational axis direction is made 1.4 times the length W1 of the air outlet 8 in the rotational direction. The wind speed is increased. This is because the airflow blown out from the blowout port 8 adheres to the end plate 17 spreading in the direction of the rotation axis toward the downstream and the airflow spreads. The larger the magnification, the larger the angle between the airflow direction and the end plate 17. This is because the adhesion effect cannot be obtained and the airflow is not enlarged. Here, the wind speed at the time of drying the clothes is preferably 0.7 m / s or more, and it is desirable that W2 / W1 is 1.2 to 1.5 times from FIG. Moreover, although the adhesion effect is affected by the wind speed of the airflow, it has been confirmed that the result is the same if the wind speed is about 2 to 3 m / s.

  6 and 7B, the length H2 of the intermediate plate 16 in the airflow direction is 1.0 to 0.85 times the length H1 of the central plate 15 in the airflow direction. The wind speed can be increased by making it 7 times smaller. Here, if it is 0.7 times or less, the wind speed may be further increased, but if it is 0.3 times or less, the length H2 of the intermediate plate 16 becomes extremely shorter than the length H1 of the central plate 15, and the It is conceivable that the wind direction is not changed by the plate 16. Therefore, since the minimum value is 0.3 times and the wind speed is 0.7 m / s or more, the maximum value is 0.8 times or less from FIG. Is desirable.

  Moreover, as shown in FIG.6 and FIG.7 (c), a wind speed can be raised by making length L2 of the intermediate | middle board 16 into 1.3 time with respect to the length L1 of the rotation direction of the center board 15. FIG. Here, there is a possibility that the wind speed increases even when the magnification is 1.3 times or more. However, if the magnification is too high, the inclination angle of the intermediate plate 16 in the airflow direction with respect to the inclination angle θ1 of the center plate 15 with respect to the airflow direction. Since θ2 increases and airflow does not flow along the intermediate plate 16 and peeling occurs on the surface of the intermediate plate 16 to cause a pressure loss, it is desirable that the ratio be up to 1.5 times. Therefore, in order to set the wind speed to 0.7 m / s or more, it is desirable to set it to 1.1 to 1.5 times from FIG.

  Thereby, since the wind speed of the airflow applied to clothes can be raised, the drying time of clothes can be shortened and there exists an effect that it is energy saving.

  Further, as shown in FIG. 4A, the wind direction changing plate 14 has a curved surface. The curvature of the curved surface is preferably arranged to be around Φ200.

  Thus, according to the clothes drying apparatus of Embodiment 1 of this invention, the frictional force with an airflow and the wind direction change board 14 falls because the wind direction change board 14 has a curved surface, and the pressure loss of the flap 13 whole is reduced. Therefore, the amount of airflow that can be guided into the flap 13 can be increased, and the drying time of clothes can be shortened.

  Further, as shown in FIG. 4A, a certain distance is provided between the end portion of the flap 13 and the end portions of the central plate 15 and the intermediate plate 16.

  Thus, according to the clothing drying apparatus of Embodiment 1 of the present invention, by setting the position of the wind direction changing plate 14 in the middle of the flap 13, the air flow sent by the blowing means 5 is reduced in pressure loss. However, the amount of air that can be guided to the flap 13 and can be controlled by the air direction changing means 9 is increased, and the drying time of the clothes can be shortened.

  Further, when the central plate 15 and the intermediate plate 16 are projected in the airflow direction as shown in FIG. Since the flow path space of the airflow flowing through can be secured and the pressure loss is not increased, the same effect is obtained.

  As shown in FIG. 4A, the end of the flap 13 and the end of the end plate 17 are designed so that the positions thereof coincide with each other, and the end plate shown by the dotted line in FIG. The portion surrounded by the surface that does not come into contact with the airflow and the flap 13 is sealed.

  As described above, according to the clothing drying apparatus of Embodiment 1 of the present invention, the portion that does not become the flow path of the air flow is blocked, thereby preventing the divergence of the air flow passing through the flap 13 and reducing the pressure loss.

Rotating means 24 for rotating 10, driving means 12 for rotating the guide wing 23 on the other side of the guide wing 23, and a plurality of wind direction changing plates 14 that penetrate the rotating shaft 10 and are fixed in a substantially C shape. It is set as the structure which consists of. Of the wind direction changing plates 14, the central two plates located at the center are the central plate 15, the two adjacent to the central plate 15 are the intermediate plates 16, and the one located closest to the end is the end plate 17.

The air flow at the center of the air flow 8 is controlled with a gentle inclination, and the air flow at the end of the outlet 8 where the wind speed is reduced is controlled with a large inclination, so that the pressure loss in the guide vanes 23 is reduced. Balanced with the wind speed distribution, the wind speed of the airflow sent from the blowing means 5 can be made uniform.

  As shown in FIG. 12, the wind direction changing plate 14 is projected from the end of the rotating shaft 10 in the axial direction of the rotating shaft 10 so as to have a circular shape.

(Embodiment 4)
In the fourth embodiment of the present invention, the same parts as those in the first to third embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

  FIG. 14 is a cross-sectional view of the main body 1 according to the fourth embodiment of the present invention.

  First, the configuration of the fourth embodiment will be described.

  As shown in FIG. 14, the main body 1 includes a blowing unit 5 and a control unit 6, an intake port 7 for taking in indoor air on the upstream side of the blowing unit 5, and an outlet on the downstream side of the blowing unit 5. 8 is provided, and the air inlet 7 and the air outlet 8 are connected by an air passage. Moreover, the main body 1 is configured to include a wind direction changing means 9 in the vicinity of the air outlet 8.

  As shown in FIG. 14, when the wind direction changing means 9 is reciprocated in the rotation direction of the rotary shaft 10, in order to apply wind to the end of the clothing as shown by the dotted line in the figure, the rotation angle of the driving means 12 is increased. There is a need to. At this time, the control unit 6 performs control so that the drive speed of the drive unit 12 becomes slower as the rotation angle of the drive unit 12 increases.

  Thus, according to the clothes drying apparatus of Embodiment 4 of this invention, drying unevenness can be prevented by lengthening the ventilation time with respect to the clothing which exists in the position shifted from the blower outlet, and shortening drying time. And can save energy.

(Embodiment 5)
In the fifth embodiment of the present invention, the same parts as those in the first to fourth embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

  FIG. 15 is a cross-sectional view of the main body 1 according to the fifth embodiment of the present invention.

  First, the configuration of the fifth embodiment will be described.

  As shown in FIG. 15, the infrared sensor 26 is installed in the vicinity of the air outlet 8 of the main body 1 and detects the temperature of an object existing in the blowing direction. A heat source 27 is installed inside the main body 1.

  Although it does not specifically limit as the infrared sensor 26, Thermal type infrared sensors, such as a thermopile, a pyro, and a thermistor, and quantum type infrared sensors, such as a photodiode, can be used.

  The heat source 27 is not particularly limited, and various commonly used heaters such as a carbon heater, a ceramic heater, a nichrome heater, and a halogen heater, and a temperature supply from the outside using a heat exchanger can be used.

  Next, the operation of the fifth embodiment will be described.

  When normal temperature air is blown to moisture-containing clothing, the temperature of the moisture-containing portion of the clothing decreases due to the property of removing heat from the object surface when the moisture evaporates. Using this, a temperature drop is detected by the infrared sensor 26, a place containing moisture in the clothing is specified, and the wind direction changing means 9 is controlled in that direction. Moreover, after specifying the place containing a water | moisture content, the heat source 27 is actuated and a warm air is ventilated. On the other hand, if no decrease in temperature is observed even when air is blown to the clothing, it is determined that the clothing has been dried, so the air blowing means 5 is stopped and the air direction changing means 9 is used to blow the air outlet 8 of the main body 1. Put the lid on.

  Thus, according to the clothing drying apparatus of Embodiment 7 of this invention, the drying unevenness of clothing can be eliminated and the drying time of clothing can be shortened.

  Moreover, the drying time can be further shortened by blowing warm air.

  Further, by detecting the end of drying of the clothes, unnecessary air blowing is not performed, so that energy can be saved.

  FIG. 16 shows a detectable region and a partial region by the infrared sensor 26, and details of the temperature detection method will be described.

  Here, as shown in FIG. 16, when the object temperature is detected by the infrared sensor 26, the detectable area 28 is a size that can detect at least the entire clothes hung on the bag, and the detectable area 28 is 3 × 5. An area obtained by dividing the cell into 15 parts can be cut out as a partial area 29, and the object temperature for each partial area 29 can be detected.

  In the clothes drying operation by the temperature detection method described above, first, the surface temperature of the clothes for each partial region 29 is measured by the infrared sensor 26 before blowing, and the surface temperature at this time is set as the reference temperature. Next, when the room temperature air is blown, the surface temperature of the wet clothing decreases, so the measured value of the surface temperature at that time is equal to or lower than the reference temperature, and it can be determined that the clothing is wet. At this time, among the partial areas 29 of the detectable area 28, only the partial area 29 where the clothes are present is lower than the measured value of the partial area 29 where the clothes are not present. can do. Therefore, the swing angle at which the air flow is blown with the partial area 29 where the clothes are present as the blow target, that is, the angle at which the flap 13 or the guide blade 23 is rotated in the rotation direction of the rotary shaft 10 is determined by the driving means 12. It is made to operate so that air current is applied to the whole clothing by swinging repeatedly.

  Since all clothing is wet in the initial stage of drying, the partial region 29 where the clothing is present while air current is diffused throughout the clothing existing in each partial region 29 and the flap 13 or the guide blade 23 is swung by the driving means 12. Make the air flow evenly.

  While drying while applying airflow to the clothing, the surface temperature of the clothing is measured by the infrared sensor 26, and the dry state of the clothing is grasped from the difference between the measured value and the reference temperature.

  Here, for example, when a user hangs clothes, if he / she hangs thick clothing on the center part of the bag and hangs thin clothes on the edge part of the bag, the thick clothes in the center part are difficult to dry and the end part is thin. Because the clothes of this product are easy to dry, unevenness may be easily caused to dry. In such a case, in the partial area 29, the difference obtained by subtracting the measured value from the reference temperature for the end region is smaller than the difference obtained by subtracting the measured value from the reference temperature for the central region. Since it can be determined that the clothing in the central area contains more moisture, the wind direction changing means 9 is reversed, and the driving means 12 is controlled so that the airflow is diffused and concentrated in the center. As a result, drying unevenness is reduced, clothes can be dried in a short time, and energy saving is achieved. Furthermore, when the difference which subtracted the measured value from the reference temperature is different for the regions arranged in the rotation direction of the rotating shaft 10 of the partial region 29, the difference obtained by subtracting the measured value from the reference temperature is small, that is, included in the clothing. When the airflow is passed through an area where moisture is low, the rotational speed of the driving means 12 is increased to increase the swing speed, the time for applying the airflow to clothing is shortened, and conversely, the difference between the reference temperature and the measured value is subtracted. When the airflow is passed through an area where there is a large amount of moisture, that is, clothing is contained, the rotational speed of the driving means 12 is slowed down to slow down the swing so that the airflow is applied to the clothing for a long time. This reduces the unevenness of drying of the entire clothes, shortens the time for drying clothes, and saves energy.

  In the above driving operation, the angle at which the swing angle is further increased is the angle connecting the rotary shaft 10 and the partial region 29. However, even if the swing angle is narrowed so as to be within 10 to 15 degrees with respect to this angle. The airflow blown out from the wind direction changing means 9 becomes a jet and spreads at about 15 degrees, so that the airflow can be sent to the target partial region 29 even if the swing angle is set to the inner side. By doing in this way, since airflow leaks outside the partial area 29 to be blown, that is, the airflow not hitting the clothing can be reduced as much as possible, there is an effect that the drying of the clothing is shortened and energy is saved.

  Moreover, when the heat source 27 is put in and hot air is put in and dried, the drying speed can be increased. In that case, after drying with warm air for one hour, for example, the heat source 27 is turned off, air at normal temperature is blown for a certain period of time, and the clothing once warmed with warm air is cooled with normal temperature air, and then the surface temperature of the clothing is again measured by the infrared sensor 26. Repeating the measurement operation and periodically checking the dryness of the clothing will reduce the drying time of the clothing by controlling the wind direction so that the airflow is applied to the clothing containing a lot of moisture as in the above operation. There is an effect of energy saving.

  Furthermore, as shown in FIG. 15, by providing a notification means 30 for notifying the user that clothing drying has been completed inside the main body 1, it is possible to recognize that clothing drying has been completed, and to improve the usability of the clothing drying apparatus. There is an effect to improve. As an example of the notification means 30, for example, an LED lamp as a display lamp may be provided on the external appearance of the main body 1 so that it emits light when clothing drying is completed. As another example, a buzzer that emits sound is used to dry clothing. A similar effect can be obtained even if the user is made aware that the clothing drying has ended by generating a sound when the user finishes.

  As described above, the garment drying apparatus of the present invention can apply a wide and uniform air flow continuously to a wide variety of clothes that have been dried, and also to a small amount or a thick laundry. It can be applied intensively and the drying time can be shortened, and can be applied to a bathroom clothes dryer or a dehumidifier equipped with a blowing means.
