Note that FIG. 2(a) corresponds to the M - M cross - section in FIG. 2(b), and FIG. 3 corresponds to the N - N cross - section in FIG. 1.

[0027] FIG. 2(a) shows the drying space 30 shown in FIG. 1 as viewed from the indoor side of the outer wall 13. As shown in FIGS. 1 and 2(a), the drying space 30 includes a first space 30A provided in the wall body located in the shed 12 and a second space 30B provided in the wall body located below the first space 30A. The first space 30A and the second space 30B communicate with each other and are provided so as to form an integral space.

[0028] Both the first space 30A and the second space 30B are provided within the wall body of the outer wall 13 located on the wife's side of the house 1. The first space 30A in the attic 12 includes the area directly below the building 111 and is formed in a region spanning the entire width of the frontage on the wife's side. Also, the first space 30A includes the area directly above the second space 30B and communicates with the second space 30B. As shown in FIGS. 2(b) and 2(c), the second space 30B is arranged adjacent to the indoor spaces on the first and second floors.

[0029] As shown in FIG. 3, a plurality of living rooms 20 are provided inside the house 1. The outer wall 13 on the wife's side extends from the first floor to directly below the building 111. The outer wall 13 is a wall that partitions the outdoor space and the indoor space of the house 1 and is one aspect of the outer peripheral wall in the house 1.

[0030] The outer wall 13 is provided with a heat insulating material 14 within the wall body. The heat insulating material 14 in the outer wall 13 is provided in the portion that partitions the indoor spaces on the first and second floors and the outdoor space and is not provided in the attic 12 portion. The heat insulating material 14 is also provided in the ceiling 16 that partitions the attic 12 and the living room 20 on the second floor and under the floor on the first floor. The attic 12 has a sloped ceiling following the shape of the roof 11, and no heat insulating material is provided on the roof 11.

[0031] In this way, in the house 1, the heat insulating material 14 is arranged so as to surround the indoor space, forming a heat insulation line. The second space 30B is disposed inside the heat insulation line of the outer wall 13. Note that the material, shape, etc. of the heat insulating material 14 forming the heat insulation line are not particularly limited.

[0032] The second space 30B is preferably provided between the inner wall 15 provided on the indoor side inside the heat insulation line of the outer wall 13 with an inner dimension width W of about 200 mm to 300 mm. From the perspective of ensuring the indoor space, more preferably, the depth W of the second space 30B is 200 mm. The depth W shown in FIG. 3 indicates the inner dimension in the bay direction in the house 1.

[0033] The first space 30A includes the outside of the heat insulation line of the outer wall 13 and the part directly below the building 111, and is provided inside the outer wall 13. In the illustrated embodiment, the first space 30A is a space with an inner dimension (depth) of about 200 mm to 300 mm partitioned by the outer wall 13 and the inner wall 15 in the attic 12. Note that the first space 30A is not limited to the illustrated configuration as long as it is a space inside the outer wall 13 and includes the attic 12, and may be configured to include the entire space of the attic 12 inside the outer wall 13.

[0034] Note that, as shown in FIG. 1, the first space 30A does not necessarily have a configuration that includes the part directly below the building 111 and is formed to span the entire frontage of the gable side, and may have any space shape as long as it is a space shape that communicates with the part directly above the second space 30B.

[0035] The drying space 30 is provided with a movable member C that can be opened or closed to open or close the communication portion between the first space 30A and the second space 30B. When the movable member C is opened, the first space 30A and the second space 30B are connected to form an integrated space in which air can flow. When the movable member C is closed, the first space 30A and the second space 30B are partitioned into individual spaces, and the air in both spaces cannot flow.

[0036] The movable member C is provided so as to be rotatable about a rotation axis, for example, and can be configured such that when it rotates upward to an upright position, the first space 30A and the second space 30B communicate with each other, and when it rotates to a horizontal position, the first space 30A and the second space 30B are partitioned. It is preferable that a heat insulating material 14 is provided on the surface of the movable member C on the attic 12 side. Further, the movable member C is preferably controlled to open and close by a control unit (not shown). Note that the movable member C is not limited to a single member provided between the first space 30A and the second space 30B, and for example, a configuration in which a plurality of communication portions between the first space 30A and the second space 30B are dispersed and a plurality of movable members C for opening and closing each of them are provided may be adopted.

[0037] The drying device 10 further includes a conveying unit 50 that suspends the laundry and moves the laundry within the second space 30B. In the drying space 30, the laundry is configured to be dried while being moved within the second space 30B by the conveying unit 50. The conveying unit 50 includes at least the height direction (vertical direction) of the second space 30B as the conveying direction of the laundry. Note that FIG. 3 schematically shows the movement of the conveying unit 50, and the illustrated form is not limited thereto.

[0038] As shown in FIG. 2(b), on the second floor, the second space 30B is provided adjacent to, for example, the storage room 221. The storage room 221 can store the dried laundry. The storage room 221 is arranged adjacent to the living room 22. The second space 30B may also be provided adjacent to this living room 22. Such a living room 22 can be exemplified by the master bedroom in the house 1, and the storage room 221 can be exemplified by a walk-in closet provided in the master bedroom.

[0039] An opening 222 is provided between the storage room 221 and the second space 30B, and the laundry can be taken in and out with respect to the second space 30B. A door 223 that can be opened and closed is provided at the opening 222. The indoor side of the door 223 is the storage room 221, and a take-out part 224 is provided on the outdoor side. The laundry dried in the second space 30B can be taken out from the second space 30B through the take-out part 224 by opening the door 223. The taken-out laundry can be directly stored in the storage room 221.

[0040] Also, as shown in FIG. 2(c), on the first floor, the second space 30B is provided adjacent to, for example, the laundry room 21. The laundry room 21 is a space for doing laundry, and for example, a washing machine 211 is installed therein. An opening 212 is provided between the laundry room 21 and the second space 30B, enabling laundry to be taken in and out of the second space 30B. A door 213 that can be opened and closed is provided at the opening 212. The indoor side of the door 213 is the laundry room 21, and a drying section 214 is provided on the outdoor side. After washing in the laundry room 21, the door 213 of the laundry room 21 can be opened without moving the laundry, and the laundry can be dried from the drying section 214 to the second space 30B of the drying space 30.

[0041] The conveying unit 50 includes an endless conveyor that circulates and moves within the second space 30B. As the endless conveyor, a rotating belt 51 that is supported in an endless shape within the second space 30B and is provided so as to be movable on a circulation track can be exemplified. As shown in FIG. 2(a), the rotating belt 51 has a substantially rectangular circulation track that moves in the height direction and also in the beam row direction within the second space 30B. For example, it is preferable that a driving sprocket is provided on the rotating belt 51 and is controlled by a control unit (not shown). The endless conveyor is not limited to the rotating belt 51, and a chain that is rotationally driven via a sprocket may also be used.

[0042] FIG. 4 is an explanatory diagram showing a configuration example of the second space 30B and the laundry room 21, and FIG. 5 is an explanatory diagram schematically showing a part of the conveying unit 50.

[0043] As shown in FIG. 4, a drying section 214, which is a space for drying laundry, is provided adjacent to the laundry room 21. When the washing is completed, the door 213 provided at the opening 212 of the laundry room 21 can be opened without significantly moving from the location of the washing machine 211, and the laundry can be dried from the drying section 214 to the second space 30B of the drying space 30.

[0044] The drying section 214 is provided with an operation section 215 and a loading / unloading pole 53 extending into the second space 30B. The operation section 215 is provided with input means such as switches for operating the loading / unloading pole 53 and the rotating belt 51. The rotating belt 51 of the conveying unit 50 is provided with a plurality of locking portions 52 for suspending laundry. The loading / unloading pole 53 is provided with a telescopic arm 531 extending into the second space 30B, and a hanger 60 suspended from a hook 532 at the tip can be hooked on the locking portion 52 of the rotating belt 51.

[0045] As shown in FIG. 5, as an example, the hanger 60 includes a support portion 63 for suspending and supporting laundry, and a laundry holding portion 64 attached to the support portion 63 and made of a lattice-like body, a mesh-like body, or a basket-like body having a large number of openings. The laundry holding portion 64 can be opened and closed around a rotation axis 65, and is configured to sandwich the laundry inside and be able to dry the laundry by air drying. The laundry holding portion 64 is not limited to being formed in a rectangular box shape, and may have any shape as long as it can move within the second space 30B.

[0046] In the hanger 60, a first hook 61 and a second hook 62 are provided on a support portion 63 extending upward from the laundry holding portion 64. The first hook 61 is configured to be lockable to the tip of the telescopic arm 531 of the loading / unloading pole 53. The second hook 62 is provided above the first hook 61 and protrudes on the side opposite to the first hook 61. The second hook 62 is configured to be lockable to the locking portion 52 of the rotating belt 51.

[0047] For example, when the telescopic arm 531 extends and the hanger 60 hooked on the telescopic arm 531 is inserted from the drying section 214 into the second space 30B, the second hook 62 of the hanger 60 is locked to the locking portion 52 of the upwardly moving rotating belt 51, and starts to move upward together with the rotating belt 51. As a result, the laundry held by the hanger 60 circulates and moves in the second space 30B of the drying space 30. The laundry dries while circulating and moving in the second space 30B.

[0048] By using such a hanger 60, laundry can be dried flat, so that it can be dried while preventing deformation in the second space 30B. It is preferable that the take-out part 224 of the storage room 221 has the same configuration as the drying part 214, and the laundry on the hanger 60 can be taken in and out using the same take-in and out poles 53. Without moving around the inside of the house 1 much, it becomes possible to take in and store the laundry dried in the storage room 221.

[0049] The hanger 60 preferably has a content sensor and a humidity sensor (not shown) provided, for example, in the laundry holding part 64. The content sensor detects the presence or absence of laundry in the laundry holding part 64. The humidity sensor detects the humidity inside the laundry holding part 64. The detection results of these sensors are transmitted to the control unit, the presence or absence of laundry and the drying state of the laundry are determined, and the operation of the conveyance unit 50 is controlled.

[0050] For example, when a hanger 60 without laundry is detected by the content sensor, the movement of the rotary belt 51 can be controlled to place the hanger 60 so that it is easy to operate when taking in the laundry from the washing room 21. Also, for example, when it is detected by the humidity sensor that the humidity inside the laundry holding part 64 is equal to the indoor humidity, it is determined that the drying of the laundry is completed, and the completion of drying can be notified through appropriate transmission means.

[0051] Note that a plurality of endless conveyors such as the rotary belt 51 in the conveyance unit 50 may be provided in multiple sets in the second space 30B, and may be configured so that a plurality of rotary belts 51 can be selectively used according to the type of laundry, the drying state, etc.

[0052] In the drying device 10, a plurality of ventilation openings are provided in the drying space 30 where the laundry is taken in and out as described above, and the ventilation mode inside the drying space 30 is controlled. As shown in FIG. 3, the first space 30A and the second space 30B of the drying space 30 are each provided with a ventilation opening communicating with the outside (outdoor side ventilation opening) and a ventilation opening communicating with the inside (indoor side ventilation opening).

[0053] Specifically, the first space 30A is provided with a first ventilation opening 1A as an outdoor ventilation opening communicating with the outdoors and a second ventilation opening 2A as an indoor ventilation opening communicating with the indoors. A duct 201 is connected to the second ventilation opening 2A. The duct 201 communicates with an air supply opening 202 in the ceiling 16 of the living room 20 on the second floor.

[0054] On the second floor level, the second space 30B is provided with a third ventilation opening 3B as an outdoor ventilation opening communicating with the outdoors and a fourth ventilation opening 4B as an indoor ventilation opening communicating with the indoors. Further, on the first floor level, the second space 30B is provided with a fifth ventilation opening 5B at the bottom as an outdoor ventilation opening communicating with the outdoors and a sixth ventilation opening 6B at the bottom as an indoor ventilation opening communicating with the indoors. As shown in FIG. 3, the third ventilation opening 3B is provided above the fifth ventilation opening 5B and is the uppermost outdoor ventilation opening within the second space 30B. Also, the fourth ventilation opening 4B is provided above the sixth ventilation opening 6B and is the uppermost indoor ventilation opening within the second space 30B. The ventilation method of the drying space 30 is the first type of ventilation. As the drying device 10, ventilation devices 40 are provided for each of these plurality of ventilation openings (1A, 2A, 3B, 4B, 5B, 6B). The ventilation device 40 is controlled to mechanically ventilate the air within the drying space 30 for drying laundry. The ventilation device 40 can operate according to a continuous operation or an intermittent operation mode. Note that, in this embodiment, an example where the ventilation method of the drying space 30 is the first type of ventilation is shown, but the ventilation method of the drying space 30 is not limited to this and may be the second type of ventilation or the third type of ventilation.

[0055] Referring to FIG. 1, in the house 1, the roof 11 receives solar radiation from the external environment and becomes hot, especially in summer. When the roof 11 warms up, the air in the attic 12 also warms up and becomes hot. The drying device 10 is configured to be able to effectively utilize the air warmed in the attic 12 to dry laundry.

[0056] Referring to FIG. 3, the movable member C that opens or closes the communication portion between the first space 30A and the second space 30B is controlled to open and close, for example, based on the solar radiation conditions. When the movable member C is opened, the first space 30A and the second space 30B are connected to form an integrated space where air can flow. The warmed air in the first space 30A can also flow into the second space 30B. When the movable member C is closed, the first space 30A and the second space 30B are partitioned, and the air in the first space 30A does not flow into the second space 30B.

[0057] FIG. 6 is a table showing an example of ventilation control conditions in the drying space 30, and FIG. 7 is a table showing a configuration example of the operations of each part for each ventilation control condition shown in FIG. 6. FIG. 8 is an explanatory diagram schematically showing the ventilation modes in cases of conditions 1 to 3 in the ventilation control conditions, and FIG. 9 is an explanatory diagram schematically showing the ventilation modes in cases of conditions 4 to 7 in the ventilation control conditions.

[0058] When there is solar radiation, for example, on a sunny day, the air in the attic 12 of the house 1 is warmed, and the first space 30A in the drying space 30 located in the attic 12 can be used as a heat reservoir. As shown in FIG. 6, in the ventilation control conditions in the drying space 30, first, the solar radiation conditions are divided into "solar radiation / yes" when solar radiation is obtained and "solar radiation / no" when solar radiation is not obtained. That is, conditions 1 to 3 are when solar radiation is obtained, and conditions 4 to 7 are when solar radiation is not obtained.

[0059] As shown in FIG. 7, in conditions 1 to 3 where solar radiation is obtained, such as on a sunny day, the movable member C is opened to connect the first space 30A and the second space 30B. On the other hand, in conditions 4 to 7 where solar radiation is not obtained, such as at night, on a rainy day, or on a cloudy day, the movable member C is controlled to be closed. When solar radiation is not obtained, the air in the first space 30A is not sufficiently warmed, so the air flow between the first space 30A and the second space 30B is blocked.

[0060] Next, as the temperature condition, as shown in FIG. 6, the outdoor temperature of the house 1 is targeted. The temperature condition is divided into, for example, the case where the outdoor temperature is equal to or higher than a predetermined temperature (20°C in this embodiment) and the case where it is lower than the predetermined temperature (20°C in this embodiment).

[0061] The humidity condition targets the outdoor humidity or the indoor humidity of the house 1. For example, the outdoor humidity is divided into the case where it is 70% or more and the case where it is less than 70%, and the indoor humidity is divided into the case where it is 40% or more and the case where it is less than 40%. The outdoor temperature, the outdoor humidity, and the indoor humidity are measured by appropriate sensors or the like provided at each location.

[0062] In the drying space 30, by controlling the operation of each ventilation opening (1A, 2A, 3B, 4B, 5B, 6B) and the movable member C in the first space 30A and the second space 30B as shown in FIG. 7, it is possible to make the laundry dry more easily and improve the indoor living environment.

[0063] In the exemplary form, the air supply part in the drying space 30 is any one of the first ventilation opening 1A, the second ventilation opening 2A, the third ventilation opening 3B, or the fourth ventilation opening 4B, and the exhaust part is the fifth ventilation opening 5B or the sixth ventilation opening 6B. Depending on the temperature condition of the outdoor temperature, it is selected whether to supply air from the outdoor side ventilation opening or from the indoor side ventilation opening. Further, the air in the drying space 30 is mechanically exhausted through the fifth ventilation opening 5B provided at the lowermost part among the plurality of outdoor side ventilation openings provided in the second space 30B, or the sixth ventilation opening 6B provided at the lowermost part among the plurality of indoor side ventilation openings.

[0064] When solar radiation is obtained, the movable member C is opened, and air is mechanically supplied into the drying space 30 through the first ventilation opening 1A or the second ventilation opening 2A in the first space 30A. Further, based on the outdoor temperature condition, air is supplied from either the first ventilation opening 1A or the second ventilation opening 2A in the first space 30A. The exhaust in the drying space 30 takes different forms depending on the temperature condition of the outdoor temperature.

[0065] More specifically, in Condition 1, it is a case where solar insolation is obtained and the outdoor temperature is 20°C or higher. For example, sunny days in summer are assumed. When the temperature condition of the outdoor temperature is 20°C or higher, it is configured to exhaust from the fifth ventilation port 5B in the second space 30B.

[0066] That is, as shown in Fig. 8(a), in order to use the warmed air in the first space 30A for drying, the movable member C is opened so that the first space 30A and the second space 30B are in communication. While mechanically supplying outside air through the first ventilation port 1A in the first space 30A, the air in the drying space 30 is mechanically exhausted through the fifth ventilation port 5B to the outside of the house. Due to the pressure of the ventilation device 40, an air flow from the first space 30A to the second space 30B is formed. Warm air circulates in the second space 30B, and the laundry can be effectively dried in the second space 30B. In this case, neither air supply from the indoor side nor air exhaust to the indoor side is performed, and the air in the drying space 30 does not flow into the living space.

[0067] Since solar insolation is also obtained in Condition 2 and Condition 3, the movable member C is opened to allow the warmed air in the first space 30A to also flow into the second space 30B. In this case, since the outdoor temperature is less than 20°C, it is not preferable to take in outside air into the first space 30A, and indoor air is taken in. Therefore, in the first space 30A, warm air in the attic 12 is mechanically supplied with warm air from the indoor side through the second ventilation port 2A. Air in the living room 20 is supplied through the air supply port 202 and the duct 201 from the second ventilation port 2A.

[0068] In seasons when the outdoor temperature is less than 20°C, the humidity condition is further referred to. Based on the indoor humidity condition, exhaust is performed from either the fifth ventilation port 5B or the sixth ventilation port 6B in the second space 30B.

[0069] That is, as shown in Condition 2, when the indoor humidity is 40% or more, it is preferable to exhaust air to the outdoor side so as not to increase the indoor humidity any further. In this case, as shown in FIG. 8(b), the air in the drying space 30 is mechanically exhausted to the outdoor side from the fifth ventilation port 5B. Further, as shown in Condition 3, when the indoor humidity is less than 40%, it is preferable that the air is humidified to improve the living environment. Therefore, as shown in FIG. 8(c), the air in the drying space 30 is mechanically exhausted to the indoor side from the sixth ventilation port 6B. Thus, also in Condition 2 and Condition 3, warm air can be circulated in the second space 30B to effectively dry the laundry in the second space 30B.

[0070] On the other hand, when solar radiation cannot be obtained, the movable member C is closed. Only the second space 30B is used as the drying space 30. In the second space 30B, air is supplied from either the third ventilation port 3B or the fourth ventilation port 4B and exhausted from either the fifth ventilation port 5B or the sixth ventilation port 6B based on the temperature condition and the humidity condition.

[0071] More specifically, in Conditions 4 and 5, solar radiation cannot be obtained, but the outdoor temperature is 20°C or higher, for example, at night in summer, on cloudy days, or on rainy days. In this case, referring to the outdoor humidity for the humidity condition, when the outdoor humidity is less than 70% (Condition 4), warm outdoor air is supplied from the third ventilation port 3B, and when the outdoor humidity is 70% or more (Condition 5), indoor air is supplied from the fourth ventilation port 4B without supplying the humid outdoor air. Since it is a season when the outdoor temperature is 20°C or higher, it is preferable to exhaust the air in the second space 30B to the outdoor side, and it is configured to exhaust to the outdoor from the fifth ventilation port 5B.

[0072] That is, in Condition 4, as shown in Fig. 9(a), air is mechanically supplied from the third ventilation opening 3B to introduce outside air into the second space 30B, and the warm and relatively dry air outdoors is used for drying. The air in the second space 30B is mechanically exhausted to the outdoor side from the fifth ventilation opening 5B. Due to the pressure of the ventilation device 40, an air flow downward is formed within the second space 30B. Warm outdoor air circulates in the second space 30B, and the laundry can be effectively dried in the second space 30B. In this case, neither air supply from the indoor side nor exhaust to the indoor side is performed, and the air in the drying space 30 does not flow into the living space.

[0073] In Condition 5, as shown in Fig. 9(b), air is supplied from the fourth ventilation opening 4B to introduce indoor air into the second space 30B, and the air in the second space 30B is mechanically exhausted to the outdoor side through the fifth ventilation opening 5B. Also in this case, due to the pressure of the ventilation device 40, an air flow downward is formed within the second space 30B. Moist outdoor air does not flow into the second space 30B, and indoor air circulates, enabling the laundry to be effectively dried in the second space 30B. In this case, since the outdoor humidity is 70% or more, neither air supply from the outdoor side nor exhaust to the indoor side is performed.

[0074] When solar radiation cannot be obtained and the outdoor temperature is less than 20°C, Conditions 6 and 7 apply. It is assumed to be a day when the temperature does not rise much, such as in winter, on cloudy days, or on rainy days. Air below 20°C is considered unsuitable for drying the laundry, and indoor air is supplied from the fourth ventilation opening 4B to the second space 30B. Further, regarding the humidity condition, referring to the indoor humidity, when the indoor humidity is 40% or more (Condition 6), exhaust is performed to the outdoor side from the fifth ventilation opening 5B, and when the indoor humidity is less than 40% (Condition 7), exhaust is performed to the indoor side from the sixth ventilation opening 6B.

[0075] That is, in Condition 6, since the outdoor temperature is less than 20°C, as shown in FIG. 9(c), air is mechanically supplied from the fourth ventilation opening 4B to take in indoor air into the second space 30B. Also, air is mechanically exhausted at the fifth ventilation opening 5B to discharge the air in the second space 30B to the outdoor side. Inside the second space 30B, an air flow directed downward is formed by the pressure of the ventilation device 40. The second space 30B does not allow the inflow of low-temperature outdoor air, but circulates relatively warm indoor air, enabling the effective drying of laundry in the second space 30B. Since the indoor humidity is 40% or more, in order not to humidify further, the air in the drying space 30 is not allowed to flow into the living space, and is exhausted to the outdoor side. The ventilation mode is the same as that in the case of Condition 5 shown in FIG. 9(b).

[0076] In Condition 7, as shown in FIG. 9(d), air is supplied from the fourth ventilation opening 4B to take in indoor air into the second space 30B for use in drying. Since the indoor humidity is less than 40%, the air in the second space 30B is mechanically exhausted to the indoor side from the sixth ventilation opening 6B. An air flow directed downward is formed inside the second space 30B by the pressure of the ventilation device 40. Relatively warm indoor air circulates in the second space 30B, enabling the effective drying of laundry in the second space 30B. By exhausting to the indoor side, the air in the drying space 30 can be introduced to the indoor side, enabling the humidification of the living room 20 and improving the living environment.

[0077] Note that the operations of the first ventilation opening 1A, the second ventilation opening 2A, the third ventilation opening 3B, the fourth ventilation opening 4B, the fifth ventilation opening 5B, the sixth ventilation opening 6B, and the movable member C are collectively controlled by the control unit. However, the drying device 10 of the present disclosure is not limited to this, and a configuration in which the operation modes are individually selected by manual operation through the operation unit 215 or the like may also be possible.

[0078] With the above configuration, the drying device 10 can efficiently dry the laundry without large movements within the house 1, and it is possible to reduce the workload of the washing task. Since the drying space 30 of the drying device 10 is provided inside the wall body of the outer wall 13, it is possible to dry the laundry without squeezing the living space. Also, regardless of the weather, time zone, and season, the laundry can be dried at any time using the drying space 30. In addition, depending on the air ventilation mode of the drying space 30, it is possible to suppress the deterioration of the living environment or improve the living environment.

[0079] Note that the laundry to be dried in the drying device 10 is not particularly limited, and for example, various fabric products can be mentioned. Specific examples of the laundry include clothing such as clothes, hats, and gloves, belongings such as shoes, bags, handkerchiefs, and towels, bedding such as curtains, blankets, towel carpets, and futon covers, and anything that can be washed such as carpets and stuffed toys. Also, the house 1 is not limited to an internal heat insulation structure in which the heat insulation material 14 is arranged between the structural bodies such as the outer wall 13 or on the indoor side of the structural body, and it may have an external heat insulation structure in which the heat insulation material is arranged on the outdoor side of the structural body. Although the drying device 10 is shown as an example of a configuration provided in the house 1, it is not limited to this, and any building may be provided with a configuration having a drying space 30 inside the wall body of the outer wall 13.

[0080] In addition, although the configuration in which the laundry on the hanger 60 is taken in and out using the access pole 53 in the take-out section 224 and the drying section 214 has been illustrated, the present invention is not limited thereto. For example, the user may directly hook the hanger 60 on the locking portion 52 of the rotating belt 51 in the drying section 214 and remove the hanger 60 from the locking portion 52 in the take-out section 224 without providing the access pole 53. Further, although the house 1 is a two-story building and the second space 30B is shown as being arranged adjacent to the indoor spaces on the first and second floors, the present invention is not limited thereto. For example, the house 1 may be a single-story building and the second space 30B may be arranged adjacent to only the indoor space on the first floor. Further, for example, when the house 1 is a two-story building and there is a laundry room 21 on the second floor, the second space 30B may be arranged adjacent to only the indoor space on the second floor.
