Description

  The present invention relates to a clothes drying apparatus that accelerates drying by applying an air flow directly to clothes while dehumidifying room air in order to dry clothes that have been air-dried indoors.

  Conventionally, this type of clothing drying apparatus is known to be a dehumidifier that takes in indoor air with a fan motor and blows the dehumidified air through a heat pump to the clothing for drying, further reducing the clothing drying time. For this purpose, a configuration has been proposed in which the amount of air blown to clothing and the wind speed are improved.

  For example, Patent Document 1 proposes a configuration in which room air taken in by a fan motor is dehumidified by a heat pump and then blown out by being mixed with room air newly taken in by another fan motor.

  Hereinafter, the clothes drying apparatus described in Patent Document 1 will be described with reference to FIG.

  FIG. 6 is a longitudinal sectional view showing the configuration of the clothes drying apparatus.

  Inside the cabinet 101, a dehumidifying chamber 103 that cools and dehumidifies indoor air and reheats through a partition wall 102 provided on the upper part thereof, and a mixing chamber 104 that mixes dehumidified air and indoor air are provided. . A communication port 105 for communicating both chambers is formed at the rear of the partition wall 102.

  An air suction port 106 is formed in the front wall of the dehumidifying chamber 103. A compression refrigerator 110 including a compressor 107, a cooler 108, and a radiator 109 in the dehumidifying chamber 103, and indoor air sucked into the dehumidifying chamber 103 from the air suction port 106 were passed through the cooler 108 and the radiator 109. After that, a blower 111 sent out from the communication port 105 to the mixing chamber 104 and a dehumidified water tank 112 are arranged.

  Room air inlets 113 are formed in the left and right side walls and the rear wall of the mixing chamber 104. A blowout port 114 for mixed air of dehumidified air and room air is formed in almost the entire upper wall of the cabinet 101. A mixed air blower 115 that sucks room air from the suction port 113 into the mixing chamber 104 and mixes it with dehumidified air sent from the communication port 105 and blows it out from the mixed air outlet 114 is arranged.

  With the above configuration, the air velocity is improved by mixing the room air obtained by the mixed air blower 115 with the dehumidified air obtained by the blower 111 and blowing the air from the mixed air outlet 114 when clothes are dried.

  For example, Patent Document 2 proposes a configuration in which a main air passage that performs dehumidification and a sub air passage that does not perform dehumidification are independent of each other.

  Hereinafter, the clothes drying apparatus described in Patent Document 2 will be described with reference to FIG.

  FIG. 7 is a longitudinal sectional view showing the configuration of the clothes drying apparatus.

  An evaporator 202, a condenser 203, and a compressor 204 that constitute a refrigeration cycle are housed inside the main body 201. A main air passage 205 that performs dehumidification sequentially passes through a main suction port 206 that sucks indoor air, an evaporator 202, a condenser 203, and a centrifugal fan 207 that blows air, and finally a main air outlet 208 is provided. A sub air passage 209 that does not perform dehumidification passes through a sub air inlet 210 that sucks in indoor air, a cross flow fan 211 that blows air, and finally, a sub air outlet 212 is provided.

  Operation of the centrifugal fan 207 in the main air passage 205 and the cross flow fan 211 in the sub air passage 209 can be independently controlled.

  With the above configuration, when the clothes are dried, the sub air passage 209 improves the wind speed by sending air regardless of the dehumidifying ability of the main air passage 205.

Utility Model Registration No. 2544496 Japanese Patent No. 3627091

  In such a conventional clothing drying apparatus, a configuration for improving the wind speed of the airflow applied to the clothing has been proposed in order to shorten the drying time when drying the wet clothing, but drying is performed according to the degree of drying of the clothing. However, there is a problem that the drying time is long because the air condition cannot be controlled so as to be most promoted.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object of the present invention is to provide a clothing drying apparatus that can be controlled so as to achieve an air condition in which drying is most promoted according to the degree of drying of the clothing. To do.

In order to achieve this object, the present invention includes a dehumidifying means in the main body, and communicates the dehumidified air taken in from the first suction port and passed through the dehumidifying means to the first air outlet. A dehumidifying air passage that allows the indoor air taken in from the second air inlet to communicate with the second air outlet, and applies air to the clothing from the first air outlet and the second air outlet. In the clothes drying apparatus for drying clothes, the dehumidifying air passage is provided with a first fan motor disposed on the downstream side of the dehumidifying means and air sucked from the first suction port through the dehumidifying means. 1 suction air passage, and the 1st blower air passage which makes the 1st fan motor and the 1st blower outlet communicate, and the circulation air passage is provided with the 2nd air inlet and the 2nd air outlet A second fan motor in communication with the second suction port and the second suction port A second suction air passage that communicates the fan motor; and a second blowout air passage that communicates the second fan motor and the second air outlet. A damper is provided for communicating the first suction air passage between the dehumidifying means and the first fan motor and the second suction air passage, and when the damper is opened , the damper causes the damper to remove the damper from the damper. The second suction air path to the second suction port is closed, and at the start of clothes drying, the damper is closed and the dehumidification air path and the circulation air path are made independent to flow air, A clothing drying device that switches to an opening operation and divides a part of the air in the first suction air passage into the second suction air passage so that air flows through the dehumidification air passage and the circulation air passage; This achieved the intended purpose. It is intended to.

  According to the present invention, the dehumidifying means is provided in the main body, the dehumidifying air passage is configured to take in indoor air from the first suction port, pass the dehumidifying means, and communicate the dehumidified air to the first air outlet, In a clothes drying apparatus, comprising a circulation air passage for communicating indoor air taken in from the air inlet to the second air outlet, and drying the clothes by applying air to the clothing from the first air outlet and the second air outlet The dehumidifying air path includes a first fan motor disposed on the downstream side of the dehumidifying means, a first suction air path for allowing air sucked from the first suction port to pass through the dehumidifying means, A second fan motor that includes a first blowout air passage that communicates the first fan motor and the first air outlet, and that communicates with the second air inlet and the second air outlet in the circulation air passage. And the second suction port communicates with the second fan motor. And a second blowout air passage that communicates the second fan motor and the second air outlet, and the dehumidifying means and the first air passage are opened in the second suction air passage. A damper for connecting the first suction air path between the fan motor and the second suction air path is provided, and at the start of clothing drying, the damper is closed to make the dehumidification air path and the circulation air path independent. And then switching to the opening operation so that a part of the air in the first suction air passage is diverted to the second suction air passage so that the air flows in the dehumidification air passage and the circulation air passage.

  The clothes drying apparatus of the present invention is based on the following idea of the drying process in clothes drying.

  There are two types of drying processes: constant rate drying and reduced rate drying.

  That is, the clothing surface is still wet at the start of clothing drying, and a water film is formed on the fiber surface of the clothing. At this time, the clothing dries as the water film on the fiber surface evaporates, and at the same time, the moisture inside the fiber moves to the surface and the water film is maintained. This drying process is called a constant rate drying process, and the drying rate is such that the amount of water contained in the clothes decreases at a constant rate with time.

  In the constant rate drying process, it has been found that the drying rate is improved in proportion to the wind speed, and it is important to promote the transfer (evaporation) and diffusion of moisture between the water film on the fiber surface and the surrounding air.

  Next, as the amount of water contained in the clothing decreases, the water film on the fiber surface disappears, and the water inside the fiber exists across the gap. In the drying process in this state, moisture evaporates inside the clothing fibers. The water vapor evaporated inside the fiber reaches the fiber surface while being diffused through the gap and is released to the outside. However, since the humidity of the gap inside the fiber increases, the drying rate becomes slower than the constant rate drying. This drying process is called a rate-decreasing drying process, and the drying speed is not constant, but gradually approaches gradually until it reaches an equilibrium state where there is no transfer of moisture between the clothing and the surrounding air.

  In the rate-decreasing drying process, the evaporation of moisture occurs not inside the fiber surface but inside the fiber, so that the rate-decreasing drying rate is hardly affected by the wind speed of the airflow. Therefore, in order to improve the rate of drying, it is effective to reduce the relative humidity of the ambient air near the fiber surface, promote the diffusion and release of water vapor present in the voids inside the fiber, It is important to reduce humidity to promote moisture evaporation inside the fiber.

  Therefore, the clothes drying apparatus according to claim 1 of the present invention includes a dehumidifying means in the main body, and takes in the room air from the first suction port and passes the dehumidified means to the dehumidified air to the first air outlet. A dehumidifying air passage that communicates with a circulation air passage that communicates indoor air taken in from the second air inlet to the second air outlet, and applies air to the clothing from the first air outlet and the second air outlet. In the clothes drying apparatus for drying clothes, the dehumidifying air passage passes the first fan motor disposed on the downstream side of the dehumidifying means and the air sucked from the first suction port to the dehumidifying means. A first suction air passage, a first blow air passage communicating the first fan motor and the first air outlet, the second air inlet and the second air outlet being provided in the circulation air passage; A second fan motor communicating with the outlet, the second suction port and the second A second suction air passage that communicates the fan motor and a second blowout air passage that communicates the second fan motor and the second air outlet, and opens the second suction air passage by an opening operation. A damper is provided for communicating the first suction air passage between the dehumidifying means and the first fan motor and the second suction air passage, and when the clothing drying starts, the damper is closed to operate the dehumidification air passage. And the circulation air path is made independent, and then the air is flown, and then the operation is switched to an opening operation, and a part of the air in the first suction air path is diverted to the second suction air path, and the dehumidification air path and the The air is made to flow through the circulation air passage.

  As a result, in the constant rate drying process in which the clothing at the start of clothing drying is wet and a water film is present on the fiber surface of the clothing, the damper is closed to pass through the dehumidifying air passage and the first air outlet. In addition to the airflow blown out from the airflow, the wind speed of the airflow that reaches the clothing can be improved by the airflow that passes through the circulation air passage and blows out from the second air outlet. By this action, evaporation and diffusion of the water film on the fiber surface can be promoted, and the drying rate can be improved.

  After that, when the water film on the fiber surface of the garment disappears and the process proceeds to the rate-decreasing drying process in which moisture remains in the fiber, the damper can be opened so that the amount of air passing through the dehumidifying means is reduced to the first. By adding the air volume of the second fan motor in addition to the air volume of the fan motor, it is possible to increase the dehumidifying capacity and further reduce the relative humidity of the ambient air of the clothing. By this action, evaporation and diffusion of moisture remaining inside the fiber can be promoted, and the drying rate can be improved.

  That is, in these two drying processes, there is an effect that the drying time until the clothes drying is completed can be shortened by improving the drying speed.

In addition, the clothes drying apparatus according to claim 2 of the present invention includes a detection unit that detects the degree of drying of the clothes in the main body, and the state A in which the fiber surface of the clothes is wet from the detection information from the detection unit;
When it is determined that the state B in which moisture remains only in the fiber of the garment, and a control unit that controls the operation of the damper, and after the garment drying is started, the determination unit determines that the state A is present. The damper is held in a closed state, and when it is determined that the damper is in the state B after that, the damper is held in an opened state.

  Thereby, the determination means determines the state A that is the constant rate drying process and the state B that is the decrease rate drying process from the detection information from the detection means, so that the control means can appropriately select the condition according to the dry state of the clothes. Since the damper can be switched at the timing, the same effect can be obtained by improving the drying speed in each drying process.

  In the clothes drying apparatus according to claim 3 of the present invention, when the damper is opened, the second suction air passage from the damper to the second suction port is closed by the damper. It is characterized by.

  Accordingly, when the damper is opened to partially bypass the air flowing through the first suction air passage to the second suction air passage, the second suction air passage upstream of the damper is blocked by the damper. Thus, a bypass flow can be reliably generated. Thereby, the same effect is acquired.

  In the clothes drying apparatus according to claim 4 of the present invention, the opening area of the second air outlet is smaller than the opening area of the first air outlet, and the second air outlet is that of the first air outlet. It is provided inside the opening, and the wind speed of the airflow blown out from the second air outlet is higher than the air speed blown out from the first air outlet.

  Thereby, it is possible to blow the dehumidified air blown from the first blower outlet around the second blower outlet by the high wind speed air blown from the second blower outlet, and directly apply the dehumidified air to the clothing. In addition, since the ultimate wind speed can be improved, the drying time can be shortened.

  In the clothes drying apparatus according to claim 5 of the present invention, the main body is a substantially rectangular parallelepiped, the first air outlet and the second air outlet are provided in the upper part of the main body, and the opening shape of the first air outlet is the main body. It is a rectangle having the same shape and longitudinal direction, and the second air outlets are provided at two intervals in the longitudinal direction of the opening of the first air outlet, and each of the second air outlets is provided. The airflow blown out from the fan is characterized in that it blows in the direction of expanding in the longitudinal direction toward the outside.

  When drying clothes, when airflow is applied to clothes that have been dried over a wider range than the longitudinal width of the body of the clothes drying device, the airflow reaching distance to the clothes that are dried on the edge is dried on the front side of the body The distance from the clothing is increased, and the influence of the attenuation of the wind speed is increased, so that the wind speed reaching the clothing dried at the end when the air is blown out at the same initial speed is lowered. Claim 5 of the present invention Since the high air velocity blown out from the second air outlet expands in the longitudinal direction and blows air by the configuration of the above, sufficient air velocity can be obtained even for the clothes dried on the end, so that the drying unevenness for each clothes is reduced. The effect that it can suppress and can shorten drying time is acquired.

  According to a sixth aspect of the present invention, in the clothes drying apparatus, the dehumidifying means includes a compressor that compresses the refrigerant, a radiator that radiates the refrigerant to the supply air, a decompression mechanism that expands and depressurizes the refrigerant, and the refrigerant. Is a vapor compression heat pump that pipe-connects a heat absorber that absorbs heat from the supply air, and includes a heat absorber on the upstream side in the first suction air passage and a heat radiator on the downstream side, and the damper has the first suction air It is characterized in that the heat sink and the first fan motor in the road can be communicated with and cut off from the second suction air path.

  As a result, even when the damper is opened and a part of the air in the first suction air passage is bypassed to the second suction air passage to increase the amount of air passing through the dehumidifying means, Since the air volume balance passing through the heat radiator and the radiator does not change, the heat cycle of the heat pump is less likely to become unstable, and the dehumidifying ability can be improved stably.

  Thereby, the same effect is acquired.

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

(Embodiment 1)
FIG. 1 is a cross-sectional perspective view showing the configuration of a clothing drying apparatus 1 according to Embodiment 1 of the present invention.

  Moreover, since the idea about the drying process of the clothing in this Embodiment was already demonstrated above, description is abbreviate | omitted here.

  As shown in FIG. 1, a clothes drying device 1 having a substantially rectangular parallelepiped shape installed on a floor surface in a room has a main body 2 serving as an outer shell, sucks room air into the main body 2 and dehumidifies it, and then returns to the room again. A dehumidifying air passage 3 that blows out and a circulation air passage 4 that sucks room air and blows it out is provided.

  The dehumidifying air passage 3 includes a first fan motor 5 (for example, a sirocco fan and an AC motor). The suction side of the dehumidifying air passage 3 sucks room air from a first suction port 6 provided on the side surface of the main body 2, and guides it to the first fan motor 5 via the first suction air passage 7. . A vapor compression heat pump device 9 as a dehumidifying means 8 is installed in the first suction air passage 7.

  Here, the heat pump device 9 includes a compressor 10 that compresses the refrigerant, a radiator 11 that radiates the heat of the refrigerant to the supply air, and a decompression mechanism 12 (not shown) that is a capillary tube as an example of expanding and depressurizing the refrigerant. The heat absorber 13 that absorbs heat from the supply air is connected by a refrigerant pipe.

  About the heat absorber 13 and the heat radiator 11, heat exchange with supply air (room air suck | inhaled from the 1st inlet 6) is required. The heat absorber 13 and the radiator 11 are arranged in the first suction air passage 7 in the order of the heat absorber 13 and the radiator 11 in the air flow direction. The radiator 11 is slightly larger than the heat absorber 13. This is because, in the refrigeration cycle, the amount of heat dissipated by the radiator 11 needs to dissipate the enthalpy increase of the refrigerant when the refrigerant is adiabatically compressed by the compressor 10 in addition to the amount of heat absorbed by the heat absorber 13. A part of the air sucked from the first suction port 6 is configured to pass through the radiator 11 without passing through the heat absorber 13 inside the heat pump device 9.

  When heat is absorbed from the supply air by the heat absorber 13, the supply air becomes dew point temperature or lower and condensation occurs, and condensed water is generated on the surface of the heat absorber 13. The condensed water flows under the heat absorber 13 by gravity, and is stored in a tank 15 provided at the lowermost portion of the main body through the drainage path 14.

  The blowout side of the first fan motor 5 is configured to blow dehumidified air upward from a first blowout port 17 provided in the upper part of the main body 2 via the first blowout air passage 16.

  Next, the circulation air path 4 includes a second fan motor 18 (for example, a turbo fan and an AC motor). The suction side of the circulation air path 4 sucks room air from a second suction port 19 provided on the side surface of the main body 2, and guides it to the second fan motor 18 via the second suction air path 20. . The blowout side of the circulation air passage 4 is configured to blow out the circulation air from a second air outlet 22 provided on the upper part of the main body 2 via the second blowout air passage 21.

  As shown in FIG. 2, the 1st suction air path 7 and the 2nd suction air path 20 are arrange | positioned adjacent to the upper and lower sides. The wall surface between the dehumidifying means 8 and the first fan motor 5 in the first suction air passage 7 and the wall surface of the second suction air passage 20 are partially separated by a damper 23. . The damper 23 has a drive motor 24 (stepping motor as an example) and can be opened and closed. That is, the first suction air passage 7 and the second suction air passage 20 are partitioned when the damper 23 is closed.

  Hereinafter, the flow of the air path by the opening / closing operation of the damper 23 will be described.

  FIG. 2 is a schematic diagram showing an air flow when the damper 23 is closed, and FIG. 3 is a schematic diagram showing an air flow when the damper 23 is opened.

  As shown in FIG. 2, the operation of the damper 23 is such that the first suction air passage 7 and the second suction air passage 20 are partitioned by the closing operation to become independent suction air passages, and the first suction air passage is made by the opening operation. The air passage 7 and the second suction air passage 20 communicate with each other.

  As shown in FIG. 3, when the damper 23 is opened, the sectional shape of the second suction air passage 20 and the damper 23 are closed so as to close the second suction air passage 20 upstream of the damper 23. The shape is matched almost the same. Thereby, when the damper 23 is opened, a bypass flow from the first suction air passage 7 to the second suction air passage 20 can be surely generated.

  By installing the second fan motor 18 in the vicinity of the first air outlet 17, the second air outlet 21 can be shortened, and pressure loss is reduced, which is preferable. In Embodiment 1, it arrange | positioned in the back side space of the tongue part of the scroll-shaped casing of the 1st fan motor 5. FIG.

  A method for controlling air blowing during clothes drying that can be realized by the above configuration will be described with reference to FIG.

  FIG. 4 is a graph showing the amount of moisture contained in the clothes on the time axis, the clothes drying process, the wind speed of the airflow hitting the clothes, the change in the relative humidity of the indoor air, and the surface temperature of the clothes.

  As shown in FIG. 4, during the constant rate drying process at the start of clothing drying, the damper 23 is closed and the dehumidifying air passage 3 and the circulating air passage 4 are made to flow independently, and then the reduced rate drying is performed. When the process proceeds, the operation is switched to the opening operation, and a part of the air in the first suction air passage 7 is diverted to the second suction air passage 20 to the dehumidification air passage 3 and the circulation air passage 4. It can be changed to allow air to flow.

  As a result, in the constant rate drying process in which the clothing at the start of clothing drying is wet and a water film is present on the fiber surface of the clothing, the damper 23 is closed to pass through the dehumidifying air passage 3 and the first In addition to the airflow blown out from the blowout port 17, the wind speed of the airflow reaching the clothing can be improved by the airflow that passes through the circulation air passage 4 and blows out from the second blowout port 22. By this action, evaporation and diffusion of the water film on the fiber surface can be promoted, and the drying rate can be improved.

  After that, when the water film on the fiber surface of the garment disappears and the process proceeds to the rate-decreasing drying process in which moisture remains in the fiber, the damper 23 can be opened, so the amount of air passing through the dehumidifying means 8 is increased. By adding the air volume of the second fan motor 18 in addition to the air volume of the first fan motor 5, it is possible to increase the dehumidifying capacity and further reduce the relative humidity of the ambient air of the clothing. By this action, evaporation and diffusion of moisture remaining inside the fiber can be promoted, and the drying rate can be improved.

  That is, in these two drying processes, there is an effect that the drying time until the clothes drying is completed can be shortened by improving the drying speed.

  As described above, the basic configuration of the present embodiment has been described.

  In addition, a configuration for detecting the dryness of clothes and a detection method thereof will be described below.

  That is, as shown in FIG. 1, by providing the detection means 25 suspended in the room, it is possible to grasp each drying process with higher accuracy.

  The detection method will be described below.

  The upper part of the main body 2 is provided with detection means 25 (a thermopile capable of measuring the surface temperature of the clothes as an example) for detecting the degree of dryness of the clothes hung in the room, and receives the detection information from the detection means 25 to receive the clothes. A judgment means 26 (a program in a microcomputer mounted on the control board as an example) and a control means 27 (a control board as an example) for controlling the operation of the damper 23 are provided.

  In the above configuration, when the determination means 26 determines that the fiber surface of the garment is in a wet state A, the damper 23 is held in a closed state, and the moisture B remains in the garment fiber. If it is determined, the damper 23 is controlled to be held in the opened state. Thereby, since it is a constant rate drying process in the state A, the damper 23 can be closed and the air velocity can be increased to accelerate the drying. Further, since the state B is a decreasing rate drying process, the damper 23 can be opened to further reduce the relative humidity to promote drying. The drying process can be improved by accurately grasping the transition of the drying process by the detecting unit 25 and the determining unit 26 and controlling the operation of the damper 23 by the control unit 27.

  Here, a specific method of determining the dry state of the clothing by the determination unit 26 from the detection information by the detection unit 25 will be described with reference to FIG.

  As shown in FIG. 4, at the start of clothing drying, the clothing still contains a large amount of moisture and a water film is present on the fiber surface of the clothing. At this time, when the clothing surface temperature is measured by the detection means 25 while applying airflow to the clothing, the clothing surface temperature is about 5 to 10 ° C. lower than the ambient air. This is because moisture evaporation occurs from the water film on the fiber surface of the garment to the surrounding air, and heat is taken away when the moisture changes to water vapor, so that the temperature of the garment surface decreases. The water evaporation from the water film continues to occur constantly during the constant rate drying process, and the surface temperature of the clothes is also substantially constant. The determination unit 26 can acquire the clothing surface temperature information from the detection unit 25, for example, every minute, and can determine that the state is A while the change in the clothing surface temperature with respect to the time change does not exceed a certain value.

  Next, when shifting from the constant rate drying process to the decreasing rate drying process, the water film on the fiber surface of the garment is in a state of being fragmented, so the amount of water evaporation to the surrounding air decreases, Along with this, the surface temperature of the clothing gradually rises and approaches the temperature of the surrounding air. Accordingly, the determination unit 26 acquires the clothing surface temperature information from the detection unit 25, for example, every minute, and is in the state B when the change in the clothing surface temperature with respect to the change over time exceeds a certain value. Judgment can be made. Eventually, the surface temperature of the clothing gradually approaches the ambient air temperature, and when the temperature difference approaches zero, it is possible to detect a dry state.

  Accordingly, the clothes drying process can be accurately grasped by the detection means 25 and the determination means 26, and the damper 23 can be switched at an appropriate timing according to the drying state of the clothes by the control means 27. In the process, the drying rate can be improved.

  Next, an air flow blown out from the main body 2, an example of the shape of the air outlet, and a situation when clothes are dried will be described with reference to FIG. 5.

  As shown in FIG. 5, the 1st blower outlet 17 is a square which has the same longitudinal direction as the main body 2, and the outer dimension of opening is 350 mm x 180 mm. Two second air outlets 22 are arranged in the longitudinal direction at an interval inside the outer periphery of the first air outlet 17, that is, inside the opening of the first air outlet 17. The outer size per one second air outlet 22 is 80 mm × 6 mm, which is narrower than the first air outlet 17. Moreover, the direction of the airflow which blows off from the 2nd blower outlet 22 was made to blow in the direction which expands in a longitudinal direction, respectively.

  Here, the angle of the airflow is suspended from the center of the main body 2 to the end when it is assumed that the main body 2 is placed at a distance of 1 m at a position substantially in the center of the clothes with respect to the clothes hung in the range of 2 m in width. Since the angle when the airflow is directed toward the clothing is about 45 °, the angle of the blowout airflow at the second outlet 22 is preferably set to an angle that expands by 45 ° in the longitudinal direction with respect to the front surface of the main body 2.

  The outlet wind speed of the airflow blown out from the second air outlet 22 is made faster than the outlet wind speed of the airflow blown out from the first air outlet 17. As an example, it is desirable that the outlet wind speed of the airflow blown out from the second blower outlet 22 is at least twice the outlet wind speed of the airflow blown out from the first blowout outlet 17. Is 10 m / s, and the outlet wind speed of the second outlet 22 is 20 m / s.

  With the above-described configuration, the dehumidified air can be blown while the dehumidified air blown from the first blower outlet 17 around the second blower outlet 22 is entrained by the high-speed airflow blown from the second blower outlet 22. Can be easily applied directly to clothing, and the reaching wind speed can be improved. Further, when airflow is applied to the clothes that have been dried over a wider range than the longitudinal width of the main body 2 of the clothes drying apparatus 1, the airflow reaching distance to the clothes that are dried at the end is dried to the front side of the main body 2. The wind speed that reaches the clothes that are dried at the end when blown out at the same initial speed is reduced due to the influence of the distance attenuation of the wind speed, which is far from the clothes that are worn, but the configuration of the present embodiment Because the high air velocity blown out from the second air outlet 22 expands in the longitudinal direction and blows air, sufficient air velocity can be obtained even for clothes that are dried on the edge, so that drying unevenness for each clothing is suppressed. And the drying time can be shortened.

  The garment drying apparatus according to the present invention includes a dehumidifying air passage that dehumidifies and blows out indoor air, and a circulation air passage that circulates and blows out indoor air so that the drying speed is fastest according to the degree of drying of the clothing. Since ventilation can be controlled, it is useful as a dehumidifier having a function of drying indoor clothing.
