DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for drying clothes in a bathroom for drying laundry suspended in a bathroom.

[0002]

2. Description of the Related Art A bathroom clothes drying apparatus for drying clothes placed in a bathroom is conventionally known. The conventional clothes drying device blows out hot air into the bathroom, circulates through the bathroom, draws in the air, and blows it out again into the bathroom.
Part of the air sucked into the clothes drying apparatus is ventilated by the ventilation means.

[0003] Conventionally, the warm air circulation operation and the ventilation operation by the ventilation means are performed simultaneously from the start of the operation of drying the clothes in the bathroom by the clothes drying device.

[0004] However, if the warm air circulation operation and the ventilation operation by the ventilation means are performed simultaneously from the start of the operation, the clothes in the bathroom having a high moisture content and the air around the clothes are removed. There is a problem that it takes a long time to be heated, and it takes a long time to dry the clothes. For this reason, it is necessary to increase the amount of hot air to increase the drying effect by heating quickly, and energy costs are increased. There was a problem that becomes high.

Conventionally, the drying operation time is set by a timer irrespective of the moisture content of the clothes, so that the operation is stopped before the clothes are dried or the clothes are dried. Nevertheless, a situation occurred in which the driver continued driving.

Further, in the related art, since the clothes drying operation has been completed simply by removing the moisture of the clothes and drying the clothes, the clothes cannot be made plump.

Further, in the prior art, the drying efficiency is poor because the bathroom is heated by a clothes drying device and the laundry, which is the laundry suspended in the bathroom at ambient temperature, is heated and dried. There was a problem. Also, clothes are dried by blowing warm air from obliquely above the clothes hung from the clothes drying device provided at the substantially center of the bathroom ceiling to the clothes suspended at the substantially center of the bathroom, Since the clothes, which are laundry, have a higher moisture content as below, there is a problem that drying under the clothes does not work well even when hot air is blown from obliquely above the clothes.

When the clothes drying apparatus is operated at night,
There was a problem that the fan sound was loud.

[0009] In the clothes drying device, a louver is provided at an outlet of the drying device. In the construction, after the drying device is installed on a ceiling portion, a front panel is disposed on a lower surface portion of the drying device. Is attached to the lower surface of the ceiling.In this case, if the louver is discharged downward from the drying device so as to enter the blowout opening of the front panel, the louver will be an obstacle when installing the drying device. The louver is damaged or damaged,
When the front panel is mounted later, there is a problem that the front panel and the louver are hindered by the louvers and become difficult to mount.

Further, if the rotation angle of the louver is different from the set angle due to a manufacturing error, a construction error, or the like, there is a problem that the air blown out from the outlet is short-passed to the inlet.

Further, when the louver is rotated to switch the air blowing direction, when the rotation is overrun than the set angle and the louver is rotated, for example, warm air from the louver blows directly to the wall, and the wall is synthesized. In the case of resin, for example, there is a problem that the wall is softened and deformed.

[0012]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above points, and can effectively dry clothes, which are laundry articles, placed in a bathroom and reduce energy costs. Can be stopped automatically when the clothes are in a dry state, the ventilation operation can be automatically stopped, and the clothes can be dried so as to make them feel fuller, and the clothes can be dried quietly at night. The clothes can be effectively dried in both normal operation and nighttime operation, and the drying device can be installed without being hindered by the louver. Even if the angle is different from the set angle due to an error or construction error, the air blown out from the outlet does not short-pass to the inlet, and the louver is rotated to switch the blowing direction. It is an object to provide a full cloth dryer never rotates in the overrun of the rotation is set angle when was Unishi.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a bathroom clothes drying apparatus according to the present invention is a bathroom clothes drying apparatus for drying clothes N arranged in a bathroom 1,
Ventilation means for ventilating a part of the air sucked into the drying device 3 is provided to the drying device 3 which blows out the hot air into the bathroom 1 and circulates and sucks the inside of the bathroom 1 to blow out into the bathroom 1 again. It is characterized in that at the beginning of the operation, only the warm air circulation flow is operated without ventilating, and thereafter, the control unit 11 is provided to control to perform the warm air circulation operation and the ventilation operation by the ventilation means. Is what you do. That is, in the initial stage of the operation of the clothes drying operation mode, the ventilation fan 15
, And only the warm air circulation operation by the circulation fan 10 is performed to quickly raise the temperature in the bathroom and the temperature of the laundry placed in the bathroom to increase the saturated steam pressure in a short time. The moisture in the laundry is released into the air and dried, and if only the hot air circulation operation is continued for a certain period of time, the amount of water vapor in the circulating air increases,
Moisture is less likely to be released into the air from the laundry, but after a certain period of time from the start of operation, the circulation fan 10 is operated to ventilate part of the circulating air containing moisture to the outside,
Moisture can be effectively discharged to the outside and dried.

Further, it is preferable to provide a control unit 11 for performing a strong ventilation operation for a predetermined time from the start of the ventilation operation and thereafter switching to a weak ventilation operation.
By adopting such a configuration, since the air contains a large amount of moisture at the beginning of the operation of the ventilation fan 15, the ventilation by the ventilation fan 15 is increased to increase the ventilation air volume, and the laundry becomes dry and When the humidity gradually decreases, the operation of the ventilation fan 15 is weakened after a certain period of time as described above, so that the energy cost required for the operation of the ventilation fan 15 is reduced.

Further, a humidity sensor is provided to detect and store the initial humidity, and the operation of the ventilation means is stopped so as to end the drying when the humidity during the clothes drying operation becomes equal to the initial humidity. It is preferable to provide a control unit 11 that performs control to perform the control. As described above, the drying is terminated when the humidity (absolute humidity) obtained by the humidity sensor becomes the same as the initial humidity. Therefore, it is assumed that the moisture content of the clothes N to be dried is different, and this is until the clothes N reach a predetermined dry state (that is, The drying operation is performed (until the humidity by the humidity sensor becomes the initial humidity), and the drying is surely performed.

Further, it is preferable to provide a control unit 11 for controlling the hot air circulation operation after drying is completed.
With such a configuration, the clothing can be warmed up with warm air after drying to make it feel plump.

Further, a rotatable louver 13 is provided at the outlet of the clothes drying apparatus, and the direction of the louver 13 is changed between a clothes drying operation mode in the bathroom 1 and a heating operation mode in the bathroom. It is preferable that the louver 13 is inclined so that warm air is blown from below onto the laundry suspended from above in the bathroom 1. That is, when the clothes, which are laundry, are hung, the water content increases as the clothes are hung, so that the clothes can be heated and dried from underneath to effectively dry the clothes.

The clothes drying operation mode includes a normal operation and a night operation in which the amount of hot air circulation is smaller than that of the normal operation, and warm air blown obliquely downward during the normal operation is suspended above the apron 8. The direction of the louver 13 is set so as to blow out from the vicinity of the lower end of the lowered clothing N to the vicinity of the upper end of the apron 8, and the warm air blown obliquely downward during night driving is applied from the lower end to the upper end of the apron 8. It is preferable to set the direction of the louver 13 so that the louver 13 is blown toward the portion between the louvers. With such a configuration,
When driving at night, you can reduce the sound and dry your clothes,
During normal operation with a large air volume, warm air can be supplied directly below the clothing N suspended above the apron 8 in the bathroom 1 to directly heat and dry the clothing N from below. However, when the vehicle is running at night, it is not possible to supply hot air directly below the clothing N suspended above the apron 8 in the bathroom 1, so that heat from the hot air can be effectively collected near the apron 8 in the bathroom 1. The clothes N located above the apron 8 can be heated and dried.

Further, a rotatable louver 13 is provided at the outlet 4 of the drying device 3, and the louver 13 is positioned in the drying device 13 so as not to protrude below the lower surface portion of the drying device 3. It is preferable that a front panel 50 be provided on the lower surface of the third panel 3, and that a blowout opening 51 provided in the front panel 50 communicate with the blowout port 4. By adopting such a configuration, in installation, after installing the drying device 3 on the ceiling 2 portion, the front panel is disposed on the lower surface portion of the drying device 3 and the front panel is attached to the lower surface of the ceiling. In this case, the drying device 3 can be attached without being obstructed by the louver 13. Further, since the louver 13 is located in the drying device 3, when the front panel 50 is attached later, it is obstructed by the louver 13. The front panel 50 can be attached without being performed.

Further, the inner surface of the blow-out opening 51 of the front panel 50 is connected to the louver 13 in the clothes drying operation mode.
Is preferably inclined at the same angle as the set inclination angle. With this configuration, even if the rotation angle of the louver 13 is different from the set angle due to a manufacturing error, a construction error, or the like, the air blown out from the outlet 4 may be short-passed to the inlet 5. Not something.

It is preferable to provide a stopper for preventing the louver 13 from rotating beyond a certain angle. With such a configuration, when the louver 13 is rotated to switch the blowing direction, the louver 13 does not overrun than the set angle and does not rotate.

Furthermore, it rises along the apron 8, so that the vicinity of the floor of the washing place 7 can be effectively heated. FIG. 22 shows a graph showing the temperature distribution from the floor to the ceiling 2 at 10 minutes after the start of operation in the central part of the washing place in the bathroom 1. The temperature is substantially within the comfortable temperature range A near the ceiling 2, and the temperature near the floor of the washing room 7 is the highest, and the feet can be warmed.

Incidentally, the bathroom clothes drying apparatus according to the present invention is provided with two clothes drying operation modes as a clothes drying operation mode in the drying apparatus 3, a normal operation and a night operation. In addition, this bathroom clothes drying device has not only the clothes drying function as described above, but also a heating function for heating the bathroom, a bathroom drying function for performing bathroom drying, a blowing function, and a ventilation function. Therefore, in addition to the two clothes drying modes of the clothes drying operation mode by the normal operation and the clothes drying operation mode by the night operation, there are two heating operation modes of the preliminary heating operation mode and the heating operation during bathing, and the bathroom drying operation. Mode, clothes drying operation mode, ventilation operation mode, and ventilation operation mode.

In each of these operation modes, a target operation mode is set by operating a switch provided in an operation unit described later. When the switch is operated, the control unit 11 causes the circulation fan 10, the ventilation fan 15, the open / close valve to open and close. 25 and the like are controlled to operate in the target operation mode.

As shown in FIG. 3, in the embodiment, the operation unit includes a dressing room operation unit 27 disposed in a dressing room.
There is a kitchen operation unit 28 arranged in the kitchen and a bathroom operation unit 29 installed in the bathroom.

The preheating switch 30 is used to quickly heat the bathroom 1 with a large air flow before bathing. By operating the preheating switch 30, a preheating operation mode is set. The pre-heating operation mode includes a case where the set temperature is low and a case where the set temperature is high. The previous mode is stored. For example, when the previous mode has a low set temperature, the pre-heating switch 30 is set. Pressing the switch once causes the heating lamp (LED 30a indicating "low") to emit light, operates in the pre-heating operation mode at a low set temperature, and pressing the switch again presses the heating lamp (LED 30 indicating "high").
b) emits light, and is operated in the preheating operation mode at a high set temperature.

FIG. 5 shows a time chart of the preheating operation mode. In the time chart of FIG. 5, the suction temperature is the temperature of the suction air detected by the sensor 24 for detecting the air temperature. After the start of the operation, the opening and closing control of the on-off valve 25 is controlled by the suction temperature by the sensor 24 for detecting the air temperature. It is supposed to do. FIG. 5A shows a case where the set temperature is high. After the operation is started, for example, the control unit 11 opens the on-off valve 25 when the temperature detected by the air temperature detection sensor 24 is less than 30 ° C. and closes it at 35 ° C. or more. In FIG. 5B, when the set temperature is low, for example, after the operation is started, the on-off valve 25 is opened when the temperature detected by the air temperature detection sensor 24 is less than 25 ° C., and the temperature is 30 ° C. or more. Is controlled by the control unit 11 so as to close. Here, when a temperature equal to or higher than a predetermined temperature set in the set operation mode is detected by the air temperature detection sensor 24, the on-off valve 25 is closed, so that the hot air becomes abnormally high and the bathroom wall 6 and the like are formed. This prevents the synthetic resin portion from being softened.

Further, the circulation fan 10 continuously performs a strong operation from the beginning to the end during the operation in the preheating operation mode, thereby preheating the interior of the bathroom 1 quickly. The louver 13 has an opening angle of 90 ° with respect to the horizontal (that is, the louver 1).
3 is in a vertical position), and warm air is blown out along the wall 6 from the outlet 4 arranged along the wall 6 near the wall 6 of the ceiling 2. As shown, warm air blown downward along the wall 6 from the outlet 4 flows along the washing place 7, and furthermore, the apron 8
Rises along and forms a circulating flow which is returned to the suction port 5 of the drying device 3 again. The circulating flow heats the interior of the bathroom 1, and particularly, from the outlet 4 of the ceiling 2 to the floor of the washing place 7. Until the hot air is dispersed, it reaches the floor of the washing room 7 and the floor of the washing room 7 is effectively heated.

In the heating lamp, either the LED 30a or the LED 30b during operation in the pre-heating operation mode is lit to notify that the operation is in the pre-heating operation mode.

The switch 31 for heating during bathing is used to heat the bathroom 1 during bathing. By operating the switch 31 for heating during bathing, a heating mode during bathing is set.
The bathing-time heating operation mode includes a weak operation and a medium operation. The previous mode is stored. For example, when the previous mode is the weak operation, for example, the bathing-time heating switch 31 is set to 1
Press twice to turn on the heating lamp (LED 31a indicating "weak")
Is operated in the heating operation mode during bathing due to weak operation, and when pressed again, the heating lamp (the LED 31b indicating "medium") emits light, and the vehicle is operated in the operation mode during bathing during medium operation. ing. Here, the medium operation and the weak operation have different strengths depending on the air volume of the circulation fan 10.

FIG. 7 shows a time chart of the heating operation mode during bathing. In the time chart of FIG.
The suction temperature is the temperature of the suction air detected by the sensor 24 for detecting the air temperature. After the start of operation, the on-off valve 25 is determined by the suction temperature of the sensor 24 for detecting the air temperature.
Open / close control. For example, after the start of operation, the temperature detected by the air temperature detecting sensor 24 becomes 40
The control unit 11 controls the on-off valve 25 to be closed when the temperature is equal to or higher than 25 ° C. and to be opened when the temperature is 25 ° C. or less. In the heating operation mode during bathing, the controller 11 is controlled to stop the operation of the circulation fan 10 when the temperature of the hot water, which is the heat source detected by the hot water temperature detecting sensor 23, is equal to or lower than the set temperature. Things. By the way, as shown in the time chart of FIG. 7, when the operation is started in the bathing heating operation mode, if the detection temperature of the hot water temperature detection sensor 23 detects the set temperature or less during the operation, the circulation fan 10 is stopped. Then, when the temperature of the hot water temperature detecting sensor 23 reaches a predetermined temperature (circulation fan operation start temperature), the circulation fan 10 is operated to blow warm air from the outlet 4 to heat the bathroom. Thereby, at the time of starting the operation in the heating mode during bathing, when the hot water that is the heat source during the heating during bathing is equal to or lower than the set temperature, the operation by the circulation fan 10 is stopped,
There is no danger of blowing a cold wind to the bather M. Here, when a temperature equal to or higher than a predetermined temperature set in the set operation mode is detected by the air temperature detection sensor 24, the on-off valve 25 is closed, so that the hot air becomes abnormally high temperature.
This prevents the synthetic resin portion forming the bathroom wall 6 and the like from softening.

In the heating operation mode during bathing, the louver 13 has an opening angle of 90 ° with respect to the horizontal (that is, the louver 13 is in a vertical posture). Warm air is blown out from the outlet 4 arranged along the wall 6 directly below the wall 6, and as a result, as shown in FIG.
The hot air blown downward along the wall 6 flows along the washing place 7 and further rises along the apron 8 to form a circulating flow which is returned to the suction port 5 of the drying device 3 again,
The circulating flow heats the interior of the bathroom 1, and in particular, the hot air is not dispersed from the outlet 4 of the ceiling 2 to the floor of the washing room 7, and reaches the floor of the washing room 7, and the floor of the washing room 7. The part is effectively heated.

In the heating lamp, either the operating LED 31a or the LED 31b in the bathing heating mode is lit to indicate that the vehicle is in the bathing heating mode.

The clothes drying switch 32 hangs clothes N, which are laundry, substantially at the upper center in the bathroom 1 and dries the clothes suspended in the bathroom 1. By operating, the clothes drying operation mode is set.
There are normal driving and night driving in the clothes drying driving mode,
When the previous mode is stored and, for example, the previous mode is the normal operation, for example, when the clothes drying switch 32 is pressed once, a lamp (an LED 32a indicating "normal") is displayed.
Flashes, and is operated in the clothes drying operation mode by the normal operation, and when pressed again, the lamp (LE indicating "night") is displayed.
D32b) emits light, and the operation is performed in the clothes drying operation mode by night operation.

FIG. 9 shows a time chart of the normal operation in the clothes drying operation mode. In the time chart of FIG. 9, the suction temperature is the temperature of the suction air detected by the air temperature detection sensor 24. After the operation starts, the opening / closing control of the on-off valve 25 is controlled by the suction temperature by the air temperature detection sensor 24. It is supposed to do. For example, after the start of operation, the control unit 11 is controlled to close the on-off valve 25 when the temperature detected by the air temperature detection sensor 24 becomes 45 ° C. or higher and open the on-off valve 25 when the temperature becomes 40 ° C. or lower. I have. Also, the clothes drying switch 32
Is operated to perform the normal operation in the clothes drying operation mode, the circulation fan 10 performs the strong operation, and the normal operation LED 32a in the clothes drying operation mode lights to indicate that the normal operation is being performed in the clothes drying operation mode. It has become. Then, in the clothes drying operation mode, the ventilation fan 15 is operated, but this ventilation fan 15 does not operate immediately after operating the clothes drying switch 32 but operates the clothes drying switch 32 after a certain period of time. (After 10 minutes in the time chart of FIG. 9), the ventilation fan 15 is initially operated for a predetermined time (2 in the time chart of FIG. 9).
(0 minutes), the control unit 11 controls to perform the strong operation and thereafter perform the weak operation. here,
As described above, at the beginning of the operation (in the embodiment, 10 minutes from the start of the operation), only the circulation fan 10 is operated without ventilating (exhausting) to operate only the warm air circulating flow. Is performed by the control unit 11 to perform the hot air circulation operation and the strong ventilation operation by the ventilation fan 15 and then to perform the warm air circulation operation and the weak ventilation operation by the ventilation fan 15 for the following reasons.

That is, at the beginning of the operation of the clothes drying operation mode, the ventilation fan 15 is not operated, and the circulation fan 1 is not operated.
By performing only the warm air circulation operation by 0 and quickly raising the temperature in the bathroom and the temperature of the laundry placed in the bathroom, the saturated steam pressure is increased in a short time.
Moisture in the laundry is released into the air and dried. Then, if the above operation is continued for a certain period of time, the amount of water vapor in the circulating air increases, and it becomes difficult for moisture to be released from the laundry into the air. 10 is operated strongly to ventilate a part of the circulating air containing moisture to the outside. Here, the operation of the ventilation fan 15 is initially set to a strong operation and set to a weak operation after a certain period of time. Ventilation fan 15
At the beginning of the operation, a large amount of moisture is contained in the air, so the ventilation fan 15 is strengthened and the ventilation air volume is increased to increase the ventilation air volume. However, since the laundry becomes dry and the moisture in the air gradually decreases, as described above, After a certain period of time, the operation of the ventilation fan 15 is weakened to lower the energy cost required for operating the ventilation fan 15.

FIG. 11 is a time chart of nighttime operation in the clothes drying operation mode. In the night operation of the clothes drying operation mode, the suction temperature is the temperature of the suction air detected by the sensor 24 for detecting the air temperature. Opening / closing control is performed. For example, when the temperature detected by the air temperature detection sensor 24 becomes 45 ° C. or more after the start of operation, the on-off valve 25
, And is controlled by the control unit 11 to open the on-off valve 25 when the temperature becomes 40 ° C. or less. Further, when the clothes drying switch 32 is operated to perform the night operation in the clothes drying operation mode, the LED 32b is turned on to notify that the night operation is being performed in the clothes drying operation mode.

In the night operation of the clothes drying operation mode, the circulation fan 10 is operated in the middle. Also, the ventilation fan 15 does not operate immediately after operating the clothes drying switch 32, but starts operating after a certain time (10 minutes in the time chart of FIG. 11) by operating the clothes drying switch 32. The operation is controlled by the control unit 11 so as to be a weak operation. Here, as described above, the circulation fan 10 is set to the medium operation, and at the beginning of the operation, only the circulation fan 10 is operated without the ventilation and the operation of only the hot air circulation flow is performed. The control unit 11 performs the medium operation by 10 and the weak ventilation operation by the ventilation fan 15.
Is controlled for the following reason. That is, the reason why the circulation fan 10 is set to the medium operation and the ventilation fan 15 is set to the weak operation is to reduce the generation of noise at night, and the ventilation fan is set at the beginning of the night operation in the clothes drying operation mode. 15 is not operated, only the warm air circulation operation by the circulation fan 10 is performed to quickly increase the temperature in the bathroom and the temperature of the laundry placed in the bathroom, thereby increasing the saturated steam pressure in a short time. Thereby, the moisture in the laundry is released into the air and dried. If the above operation is continued for a certain period of time, the amount of water vapor in the circulating air increases, and it becomes difficult for moisture to be released from the laundry into the air. To prevent this, the circulation fan 10 is turned off after a certain period of time from the start of operation. This is to ventilate a part of the circulating air containing moisture to the outside by weak operation.

Here, in both the normal operation and the night operation in the clothes drying operation mode described above, a humidity sensor is provided to detect the initial humidity when the clothes drying switch 32 is pressed to set the clothes drying operation mode. (That is,
When the clothes drying switch 32 is operated, the circulation fan 10 is operated.
, The humidity (absolute humidity) in the bathroom is detected at the same time as the operation starts, or when the clothes drying switch 32 is operated, the humidity (absolute humidity) in the bathroom is detected first, and then the circulation fan 10 is operated. The controller controls the ventilation fan 15 to stop at least the operation of the ventilation fan 15 so as to end the drying when the humidity during the clothes drying operation becomes equal to the initial humidity. When the humidity becomes equal to the initial humidity in this manner, the clothing is considered to be dry, and at least the ventilation fan 15 is stopped. In the time charts shown in FIGS. 9 and 11, when the humidity of the circulation flow becomes equal to the initial humidity, the ventilation fan 15 is stopped and the circulation fan 10 is also stopped. At the same time, only the ventilation fan 15 is stopped to finish drying the laundry,
Thereafter, the controller 11 may be controlled so that only the circulation fan 10 is operated for a certain period of time to warm the clothes that have been dried with the warm air to make the clothes full.

In the normal operation and the night operation in the clothes drying operation mode, the clothes are suspended above the substantially central portion of the bathroom 1 (that is, substantially above the apron 8 as shown in FIGS. 10 and 12). The direction of the louver 13 is set so that warm air is blown from below onto the clothes N, which are the laundry. This is because when the clothes N, which are laundry, are hung, the lower part of the clothes N has a high moisture content, so that the clothes can be effectively dried by blowing warm air from below the clothes N.

In normal operation, since the amount of hot air blown from the outlet 4 provided near the wall 6 of the ceiling 2 is large, the hot air is suspended almost above the apron 8 in the substantially central portion of the bathroom 1. In this case, the warm air is directly supplied to the lower part of the clothes N, which is the laundry, and the lower part of the clothes N can be effectively heated with the warm air to dry the clothes N from below. In this case, FIG. As shown, the opening angle α of the louver 13 is set to α in FIG. 10 so that the warm air blown out from the blowout port 4 is blown out from the vicinity of the upper end of the apron 8 to the lower end of the clothing N.
It is set so as to be within the range of 1 to α2.

In the nighttime operation, as shown in FIG. 12, the amount of warm air blown from the outlet 4 provided near the wall 6 of the ceiling 2 is small. When warm air is blown out just below the clothes N, which are the laundry suspended substantially above the apron 8 in the substantially central portion of the clothes N, the hot air is dispersed on the way, and only the upper part of the bathroom N is heated. Cannot be dried by heating from below. For this reason, even if it is a small air volume, it is blown out toward the range between the upper end and the lower end of the apron 8 so that the lower part in the bathroom 1 can be effectively heated without being dispersed on the way as much as possible. As shown in FIG.
It is set to be in the range of 1 to β2,
Thereby, the garment N is dried from below by heating the vicinity of the apron 8 below the garment N, which is the laundry, by reducing the dispersion of the warm air. The opening angle of the louver 13 with respect to the horizontal in the normal operation and the opening angle of the louver 13 with respect to the horizontal in the night operation are all the size of the bathroom 1,

As described above, according to the first aspect of the present invention, there is provided a bathroom clothes drying apparatus for drying clothes disposed in a bathroom, wherein hot air is blown into the bathroom. A clothes drying device that circulates through the bathroom and sucks it in and blows it back into the bathroom is provided with ventilation means that ventilates a portion of the air drawn into the drying device. Operate only the wind circulation flow, and then
Since the control unit is provided to control the hot air circulation operation and the ventilation operation by the ventilation means, the ventilation fan is not operated in the initial stage of the operation of the clothes drying operation mode, and only the hot air circulation operation by the circulation fan is performed. The temperature of the bathroom and the temperature of the laundry placed in the bathroom can be quickly raised to increase the saturated steam pressure in a short time, and the moisture in the laundry can be released to the air and dried. By circulating a part of the circulating air containing moisture by operating the circulation fan after a certain period of time from the start of operation, the moisture can be effectively discharged to the outside and dried, As a result, it is possible to effectively dry the clothes, which are the laundry disposed in the bathroom, and reduce the energy cost.

According to the second aspect of the present invention, in addition to the effect of the first aspect, the ventilation operation is performed for a predetermined time after the start of the ventilation operation, and thereafter, the weak ventilation operation is performed. At the beginning of the operation of the ventilation fan, a large amount of moisture is contained in the air at the beginning of the operation, so the ventilation with the ventilation fan is strengthened and the ventilation air volume is increased, and the laundry is dried and the moisture in the air is reduced. As it gradually decreases,
As described above, after a certain period of time, the operation of the ventilation fan is weakened to reduce the energy cost required for the operation of the ventilation fan, and the clothes as laundry can be efficiently dried in the bathroom.

According to the third aspect of the present invention, in addition to the effects of the first or second aspect of the present invention, a humidity sensor is provided to detect and store the initial humidity.
Since a control unit is provided for controlling the operation of the ventilation means so as to end the drying when the humidity during the clothes drying operation becomes equal to the initial humidity, the humidity (absolute humidity) by the humidity sensor is determined. Since the drying is terminated when the initial humidity becomes the same as the initial humidity, it is assumed that the moisture content of the clothes to be dried is different, and the drying operation is continued until the water reaches a predetermined drying state (that is, until the humidity by the humidity sensor becomes the initial humidity). This is done to ensure drying.

Further, in the invention according to the fourth aspect, in addition to the effect of the invention according to the third aspect, a control unit for controlling the hot air circulation operation to be continued after the drying is provided is provided. After drying the clothes, the clothes can be warmed with warm air to give a plump finish, and the finish after the clothes are dried can be improved.

According to the fifth aspect of the present invention, in addition to the effects of the first aspect of the present invention, a rotatable louver is provided at the outlet of the bathroom clothes drying apparatus to dry clothes in the bathroom. Since the direction of the louver is changed between the operation mode and the bathroom heating operation mode, and the louver is inclined so as to blow warm air from below on the laundry suspended at the upper part of the bathroom in the clothes drying operation mode, Clothes, which are laundry, have a higher moisture content when suspended, but can be dried effectively by heating and drying under the clothes.

According to the sixth aspect of the present invention, in addition to the effects of the fifth aspect of the present invention, the clothes drying mode includes a normal operation and a night operation in which the amount of hot air circulation is smaller than that in the normal operation. The direction of the louver is set so that the warm air blown obliquely downward during normal operation is blown out from the vicinity of the lower end of the clothes suspended almost above the apron to the vicinity of the upper end of the apron, The direction of the louver is set so that the warm air blown diagonally downward during driving is blown toward the part between the lower end and the upper end of the apron. Also, during normal operation with a large air volume, warm air can be supplied directly below the clothing hung above the apron in the bathroom to directly heat and dry the clothing from below, and the air volume can be increased. But small night When turning, it is not possible to supply hot air directly below the clothes suspended above the apron in the bathroom, so heat generated by the warm air is effectively collected near the apron in the bathroom to heat the clothes located above the apron. Thus, the clothes can be effectively dried according to the normal operation and the night operation.

According to a seventh aspect of the present invention, in the bathroom clothes drying apparatus according to the first, fifth, or sixth aspect, a rotatable louver is provided at an outlet of the drying apparatus. The louver is positioned in the drying device so as not to protrude below the lower surface of the drying device, and a front panel is provided on the lower surface of the drying device. The blowout opening provided in the front panel communicates with the blowout opening. Since the drying device is installed, the drying device can be attached without being disturbed by the louver during the installation of the drying device, and the louver is arranged in the drying device so as not to protrude downward. Therefore, when the front panel is mounted later, the front panel can be mounted without being disturbed by the louver. As a result, the front panel can be easily mounted. Moni louver, those never damage the surface panel.

According to an eighth aspect of the present invention, in addition to the effects of the first aspect or the fifth to seventh aspects of the present invention, the inner surface of the blowing opening of the front panel is provided. Is inclined at the same angle as the set inclination angle of the louver in the clothes drying operation mode, so even if the rotation angle of the louver is different from the set angle due to a manufacturing error, a construction error, etc., the air is blown out from the outlet. The air can be dried efficiently without short-passing to the suction port.

According to the ninth aspect of the present invention, in addition to the effects of the first aspect or the fifth to eighth aspects, the rotation of the louver does not rotate beyond a predetermined angle. When the louver is rotated to switch the air blowing direction, it does not overrun than the set angle and does not rotate.For example, warm air from the louver blows directly to the wall. It is possible to prevent the wall from being softened and deformed by warm air even if the wall is made of a synthetic resin.
