As shown in FIGS. 1 and 2, the drying apparatus 1 has a housing 3 having a rectangular parallelepiped shape as a whole and a hose 5 protruding from the upper surface of the housing 3 . The housing 3 has a front panel (an example of a front portion of the housing) 32 arranged on the front side, and a body portion 31 provided with the hose 5 and arranged on the rear side. One end of the hose 5 is attached to a discharge port 317 (details will be described later) formed in the housing 3 so as to extend outside the housing 3 .

As shown in FIG. 3, the body portion 31 has a box shape with an opening on the front panel 32 side. The main body 31 has an accommodation space 300 that accommodates various devices (details of which will be described later) for blowing hot air onto the object to be dried. The housing space 300 is formed by being surrounded by a first side wall 31a, a bottom portion 31e, a second side wall 31b, a top portion (an example of a side wall having a discharge port) 31d, and a rear portion 31c. The first side wall 31 a is arranged on the right side of the housing 3 . second
The side wall 31b is arranged on the left side of the housing 3 so as to face the first side wall 31a. The bottom surface portion 31e is arranged on the bottom surface side of the housing 3 and sandwiched between the first and second side walls 31a and 31b. The bottom portion 31e is perpendicular to the first and second side walls 31a and 31b. The upper surface portion 31d is arranged on the plane side (upper surface side) of the housing 3 and arranged between the second side wall 31b and the first side wall 31a. The rear surface portion 31c is arranged on the rear surface side of the housing 3 and is arranged orthogonally to the first and second side walls 31a and 31b, the bottom surface portion 31e, and the top surface portion 31d. The back portion 31c is formed by extending from one long side of each of the first and second side walls 31a and 31b. The rear portion 31c is adjacent to the first and second side walls 31a, 31b and the top portion 31d and the bottom portion 31e.

The first and second sidewalls 31a, 31b and the rear portion 31c and bottom portion 31e have substantially flat outer surfaces. Corners where the first and second side walls 31a and 31b, the rear surface portion 31c and the bottom surface portion 31e are in contact with each other are rounded. A hose accommodating portion 8, which will be described later, is provided at a corner portion of the upper surface portion 31d. For this reason, the upper surface portion 31d has a stepped shape in which a part of the upper surface portion 31d is depressed toward the bottom surface portion 31e. Further, the first side wall 31a has a shape in which the upper surface portion 31d and the rear surface portion 31c are notched by the area where the hose accommodating portion 8 is provided. Similarly, the rear surface portion 31c has a shape in which the upper surface portion 31d and the first side wall 31a side are notched by the area where the hose accommodating portion 8 is provided.

Returning to FIGS. 1 and 2, the housing 3 has a lid portion 2 detachably provided on the first side wall 31a. The lid portion 2 is provided to prevent a power cord (not shown) housed in a later-described cord housing portion 314 (see FIG. 3) from jumping out of the housing 3 . The lid portion 2 has a thin rectangular shape extending from the substantially central portion of the first side wall 31a to each side adjacent to the back surface portion 31c and the bottom surface portion 31e. The lid portion 2 is formed with an intake port 21 configured by a plurality of rectangular through-holes. The intake port 21 is provided to draw air into the housing space 300 of the housing 3 for generating warm air to be blown to the object to be dried. A knob portion 22 is provided on the front panel 32 side of the lid portion 2 . The knob portion 22 is formed to be engageable with a hole portion 315 (see FIG. 3) formed in the first side wall 31a. By pulling the knob portion 22 toward the intake port 21 side, the locked state between the knob portion 22 and the hole portion 315 is released, and the lid portion 2 is detached from the housing 3 . The lid portion 2 has a notch portion 23 at the corner where the bottom portion 31e and the back portion 31c intersect. When the lid portion 2 is attached to the first side wall 31a, the notch portion 23 forms an opening together with the back portion 31c. This opening serves as a drawer for the power cord. For this reason, when using the drying apparatus 1, the power cord pulled out from the cord housing portion 314 can be passed through this opening, so that the power cord can be connected to the outside of the drying apparatus 1 even when the lid portion 2 is attached to the first side wall 31a. can be pulled out to Thereby, the drying apparatus 1 can operate with the lid portion 2 attached to the first side wall 31a.

As shown in FIG. 3, in the region of the first side wall 31a covered by the lid portion 2 (not shown in FIG. 3), an intake port (an example of the first intake port) 312 and a cord housing portion 314 are directed to the outside. An opening 314a is provided that opens to the outside. The intake port 312 is provided to draw air into the housing space 300 of the housing 3 for generating warm air to be blown to the object to be dried. The intake port 312 is composed of a plurality of rectangular through-holes. The intake port 312 is provided at a position corresponding to the intake port 21 when the lid portion 2 is attached to the housing 3 . Moreover, the plurality of through holes forming the air intake port 312 overlap the plurality of through holes forming the lid portion 2 when the lid portion 2 is attached to the housing 3 . As a result, even if the drying apparatus 1 is operated with the lid portion 2 attached to the housing 3 , the drying apparatus 1 can efficiently draw outside air into the housing space 300 .

An intake port (an example of a second intake port) 313 is provided in the bottom surface portion 31e. The intake port 313 is composed of a plurality of rectangular through-holes. The intake port 313 is provided to draw air into the housing space 300 of the housing 3 for generating warm air to be blown to the object to be dried. The bottom portion 31 e has a plurality of (four in this example) leg portions (an example of convex portions) 33 provided around the intake port 313 . The leg portion 33 is formed so as to protrude from the bottom portion 31 e toward the outside of the housing 3 . Since the leg portion 33 is formed to protrude toward the outside of the housing 3, when the drying apparatus 1 is placed on a predetermined place, the height of the leg portion 33 is between the bottom portion 31e and the predetermined place. You can create a gap just for the minute. Therefore, even when the drying apparatus 1 is used with the bottom surface portion 31 e facing a predetermined location, the drying apparatus 1 can pass through the air intake port 313 from the gap formed by the legs 33 to the storage space 300 of the housing 3 . can inhale air.

The drying apparatus 1 has an operation switch section 73 (see FIG. 5) that stops or continues the operation of the drying apparatus 1 according to the installation state of the housing 3 . The operation switch section 73 is provided, for example, on a main circuit board 350 which will be described later. The drying apparatus 1 also includes a sensor (see FIG. 5) for detecting the installation state of the drying apparatus 1 on the main circuit board 350, for example. This sensor has a tilt sensor 13 (see FIG. 5) that detects the tilt angle of the housing 3 . The operation switch unit 73 detects the installation state in which the intake port 312 or the intake port 21 faces the mounting surface, and stops the operation of the drying device 1 . In addition, the operation switch section 73 allows the operation of the drying apparatus 1 to continue even when the air inlet 313 faces the mounting surface. When the drying apparatus 1 dries a futon, the surface to be placed is, for example, the surface of a futon on which the drying apparatus 1 is placed. When the drying apparatus 1 dries shoes or the like, the mounting surface is, for example, a floor surface on which the drying apparatus 1 is mounted. The configuration of the operation switch unit 73 and the connection relationship with other configurations of the tilt sensor 13 will be described later.

Even if the drying apparatus 1 operates in an installation state in which the air intake port 313 faces the mounting surface, a gap corresponding to the height of the leg portion 33 is formed between the air intake port 313 and the mounting surface. Therefore, the drying device 1 can suck air into the housing 3 through this gap and the air inlet 313 . At this time, air is also drawn into the housing 3 through the intake ports 21 and 312 . Therefore, the motor 91 (details will be described later) will not over-operate. Therefore, even in this installed state, the operation switch section 73 is maintained in the ON state, and the operation of the drying apparatus 1 is continued.

When the lid portion 2 is attached to the housing 3, the surface of the lid portion 2 is substantially flush with the surface of the first side wall 31a. Further, no member protruding outward from the first side wall 31a like the leg portion 33 is formed around the intake port 21 . Therefore, when the drying apparatus 1 is installed with the intake port 21 facing the mounting surface, there is almost no gap between the intake port 313 and the mounting surface. In addition, when the lid portion 2 is removed from the housing 3 and the first side wall 31a and the mounting surface are placed facing each other, the distance between the intake port 312 and the mounting surface is increased by the amount of the removal of the lid portion 2. There is a gap between However, this gap is very small. Also, if the surface on which the dryer 1 is placed is a soft surface such as a mattress, the intake port 312 may slip into the soft surface and be blocked even if the lid portion 2 is removed. Therefore, the amount of air sucked into the housing 3 through the air inlet 313 and the air inlet 312 through this gap is not sufficient for the designed air intake amount of the drying apparatus 1 . As a result, when the drying apparatus 1 operates with the lid 2 removed from the housing 3 and the air inlet 312 facing the mounting surface, the drying apparatus 1 blows air in a designed amount. Since it tries to suck air into the housing 3, there is a possibility that the motor 91 will be over-operated. For this reason, the operation switch section 73 is turned off in this installation state, stops the operation of the drying apparatus 1, and prevents overoperation of the motor 91 and damage to the drying apparatus 1 caused by this overoperation. there is

The upper surface portion 31 d is formed with a discharge port 317 through which hot air generated from the air sucked into the housing 3 is discharged, and a hose accommodating portion 8 provided in parallel with the discharge port 317 . The hose accommodating portion 8 is formed by notching corners (corners of the housing 3) where the upper surface portion 31d, the rear surface portion 31c, and the first side wall 31a are adjacent to each other. The hose accommodating portion 8 is a rectangular parallelepiped space. When a hose tip member 53 (details will be described later) provided on the hose 5 (see FIG. 1) is accommodated in the hose accommodation portion 8, the side surface of the hose tip member 53 is positioned between the first side wall 31a and the back surface. It is sized so as not to protrude from a plane including the surface of the portion 31c.
Below the discharge port 317 and part of the back surface portion 31c, an opening 319 is formed through which an exposed surface 612a of a heater case 612, which will be described later, is exposed.

Returning to FIGS. 1 and 2, the front panel 32 is provided across opposing sides of the first side wall 31a and the second side wall 31b (that is, a portion of the open end of the body portion 31).

Further, when the resistance values of the thermistors 81 and 621 exceed this predetermined value and then fall below another predetermined value smaller than this predetermined value, the microcomputer 11 outputs a predetermined signal for restarting the operation of the heater 611. 71. When receiving these predetermined signals from the microcomputer 11 , the control section 71 controls the relays 732 and 733 to control power supply to the heater 611 .

As shown in FIG. 6, the resistor 17 constituting the resistance value measuring circuit has one terminal connected to a predetermined output terminal of the AC/DC converter 75 and the other terminal connected to one terminal of the microcomputer and the thermistor 81. It is One terminal of the resistor 19 constituting the resistance value measuring circuit is connected to another predetermined output terminal of the AC/DC converter 75, and the other terminal is connected to one terminal of the microcomputer and the thermistor 621. . The other terminals of thermistors 81 and 621 are grounded. The resistance value measuring circuit measures the resistance values of the thermistors 81 and 621 at, for example, predetermined time intervals after the drying apparatus 1 is powered on, and outputs to the microcomputer 11 a signal obtained by converting the measured resistance value into a voltage. It has become. For example, when a voltage of 5V is applied to one terminal of the resistor 17, if the thermistor 81 is open and an open failure occurs, the voltage of the other terminal of the resistor 17 becomes 5V. A voltage signal of 5V is input to . Further, when the thermistor 81 is short-circuited and a short-circuit failure occurs, the voltage of the other terminal of the resistor 17 becomes 0 V, so a voltage signal of 0 V is input to the microcomputer 11 . Similarly, for example, when a voltage of 5V is applied to one terminal of the resistor 19, if the thermistor 621 is in an open state and an open failure occurs, the voltage of the other terminal of the resistor 19 becomes 5V. A voltage signal of 5V is input to the microcomputer 11 . Further, when the thermistor 621 is short-circuited and a short-circuit failure occurs, the voltage of the other terminal of the resistor 19 becomes 0 V, so a voltage signal of 0 V is input to the microcomputer 11 . When a voltage signal of 0 V or 5 V is input from the resistors 17 and 19, the microcomputer 11 determines that the thermistors 81 and 621 are in a defective state, and controls the drying apparatus 1 via the control section 71 so as not to operate. . More specifically, the microcomputer 11 stops power supply to the heater 611 to stop hot air from being discharged from the hose 5 . Thereby, the drying apparatus 1 can be automatically stopped when an abnormal operation is detected. Also, the resistance value measuring circuit is configured to measure the resistance values of the thermistors 81 and 621 when the power cord is inserted, that is, when the power is turned on. Therefore, the drying apparatus 1 can detect an abnormality immediately before starting operation, and can prevent an abnormal operation.

Returning to FIG. 4, the LED circuit board 340 has a plurality of (three in this example) LEDs. The LED circuit board 340 notifies the user of the temperature of the air discharged from the hose 5 by controlling the light emission of the LED. For example, the LED circuit board 340 has an LED that emits red light, an LED that emits yellow light, and an LED that emits blue light. The LED circuit board 340 notifies that high-temperature air (warm air) is being discharged by emitting red LEDs, and indicates that low-temperature air (warm air) is being discharged by emitting yellow LEDs. It notifies that there is only air blowing by emitting light from a blue LED. On the front surface of the LED circuit board 340 (on the front panel 32 side), a protective member 326 made of a light-transmitting material containing a diffusion material and a spacer member 324 for providing a predetermined gap between the front panel 32 and the protective member 326 are provided. and are placed.

A screw hole is formed in the vicinity of the top of the protruding portion 320c in a direction parallel to the extending direction of the side wall 32b on the short side. Through holes 311b (see FIG. 3) are formed in the first and second side walls 31a and 31b at positions corresponding to the screw holes when the body portion 31 and the front panel 32 are superimposed and the claw portions 318 and the like are locked. It is

Also, when the main body portion 31 and the front panel 32 are overlapped and the claw portion 318 or the like is locked, the tip of the boss 320d contacts the rear surface of the main body portion 31 (the surface facing the front panel 32). A through hole 311a is formed at a position of the body portion 31 with which the boss 320d abuts. The tip of the boss 320d is threaded in the direction in which the boss 320d extends. Therefore, a screw (not shown) inserted into the through hole 311b is screwed into the screw hole of the projecting portion 320c, and a screw (not shown) inserted into the through hole 311a is screwed into the boss 320d. Furthermore, a screw is inserted into a through hole provided in the grip part 330 and fixed with a nut. Thereby, the front panel 32 is fixed to the body portion 31 .

Next, the positional relationship of each member in the housing 3 and the detailed configuration of each member will be described with reference to FIGS. 1 to 4 and FIGS. 7 to 16. FIG. FIG. 7 is a perspective view of the drying apparatus 1 with the front panel 32 and the hose 5 removed. FIG. 7(a) is a perspective view showing the appearance of the drying device 1 seen from the upper left front, and FIG. 7(b) is a perspective view showing the appearance of the drying device 1 seen from the lower right front.

As shown in FIGS. 7 and 8, the motor 91 is arranged on the side of the first side wall 31a of the housing 3 in which the intake port 312 is provided. A fan case 92a that houses a fan 92b (see FIG. 4) is arranged to face the intake port 312 with the motor 91 interposed therebetween. The fan 92b is arranged on an extension line connecting the air inlet 312 and the motor 91 . The cord housing portion 314 is formed from an opening 314a formed in the first side wall 31a toward the fan case 92a side, and is arranged side by side with the motor 91. As shown in FIG. The cord housing portion 314 is arranged closer to the back portion 31c of the housing 3 than the motor 91 is. As shown in FIG. 7B, the opening 314a of the cord housing portion 314 is arranged side by side with the intake port 312 on the first side wall 31a. The cord housing portion 314 is arranged on the rear portion 31c side, and the intake port 312 is arranged on the front panel 32 (not shown in FIGS. 7 and 8) side. Although the details will be described later, the drying apparatus 1 has a predetermined flow path in the accommodation space 300 of the housing 3 by arranging the second side wall 31b having no intake port and the fan case 92a with a gap therebetween. generate As a result, the drying apparatus 1 prevents the air from staying in the accommodation space 300 of the housing 3 and preventing the temperature from rising in the accommodation space 300 .

As shown in FIG. 8(a), the main circuit board 350 is arranged in the direction in which the motor 91 and the cord housing portion 314 (see FIG. 7) overlap (that is, the direction orthogonal to the plane including the open end of the main body portion 31). It is arranged so as not to overlap with the motor 91 and the fan case 92a. Also, the main circuit board 350 does not overlap the motor 91 and the fan case 92a when viewed from one longitudinal side of the first and second side walls 31a and 31b in a direction parallel to the first and second side walls 31a and 31b. are arranged as Here, one side in the longitudinal direction of the first and second side walls 31a and 31b is an edge forming the opening end of the main body 3 among the edges of the first and second side walls 31a and 31b. The main circuit board 350 is provided diagonally above and adjacent to the cord housing portion 314 . Therefore, the dryer 1 can be connected to the main circuit board 350 from the cord housing portion 314 without routing the power cord inside the housing 3 .

As shown in FIGS. 8A and 8B, the ventilation passage 62 is provided with a thermistor (an example of a second temperature sensor) 621 for controlling the heating section 61 . The thermistor 621 is arranged downstream of the heater 611 in the blowing passage 6 and immediately after the heater 611 . The thermistor 621 is provided to detect whether or not the temperature of the heater 611 reaches the set value during operation of the drying apparatus 1 .

As shown in FIG. 8B , a thermistor (an example of a first temperature sensor) 81 is provided inside the housing 3 of the hose accommodating portion 8 . The drying device 1 has two thermistors 81, 621 as temperature sensors. The thermistor 81 is arranged at a position facing the nozzle 54 across the upper surface portion 31 d when the hose 5 is arranged in the hose accommodating portion 8 . More specifically, the thermistor 81 is located in the accommodation space 300 of the housing 3 located below the hose accommodation portion 8 and on the rear surface portion 31c side of the main circuit board 350 (not shown in FIG. 8B). are placed. A thermistor 81 is provided to control the heating unit 61 . If the drying apparatus 1 is turned on by mistake while the hose tip member 53 is arranged in the hose accommodating part 8, hot air generated by the heating part 61 is discharged from the hose tip member 53 to the outside. Then, the hose accommodating portion 8 is heated by the hot air discharged from the hose tip member 53 and the temperature thereof rises. The thermistor 81 detects the temperature around the hose accommodating portion 8 and outputs a detection signal to the main circuit board 350 . When the control unit 71 provided on the main circuit board 350 determines that the temperature around the hose accommodation unit 8 exceeds a predetermined threshold based on the detection signal input from the thermistor 81 via the microcomputer 11, the heating unit 61 operates. to stop. In this way, the drying device 1 can detect an abnormal operation and automatically stop.

The fixed portion 93 has a claw portion 93b which is formed by cutting out a portion of the fixed portion 93 and bending the claw portion 93b toward the motor 91 so as to be substantially parallel to the back surface portion 31c. A through hole is formed in the claw portion 93b. The fixing portion 93 is arranged in the body portion 31 with the claw portion 93b fixed to the boss 311c by screwing a screw inserted into the through hole into a screw hole formed in the boss 311c.

Next, the blower section 9 and the blower path 6 will be described with reference to FIGS. 1 to 8 and FIGS. 9 to 12. FIG. FIG. 9 is an orthographic view of the blower 9 and the blower passage 6 with the blower 9 attached to the blower passage 6 . A plan view of the air blowing section 9 and the air blowing passage 6 is illustrated in the upper part of FIG. 9 . In the middle part of FIG. 9, a left side view, a front view, and a right side view of the blowing unit 9 and the blowing passage 6 are illustrated in this order from the left. A bottom view of the blowing unit 9 and the blowing passage 6 is shown in the lower part of FIG. 9 . In FIG. 9, illustration of a rear view of the air blowing section 9 and the air blowing passage 6 is omitted. FIG. 10 is an orthographic view of the air duct 6. FIG. A plan view of the air duct 6 is illustrated in the upper part of FIG. 10 . In the middle part of FIG. 10, a front view, a right side view and a rear view of the air duct 6 are illustrated in this order from the left. A bottom view of the air duct 6 is shown in the middle lower part of FIG. 10 . 10, illustration of a left side view of the blowing passage 6 is omitted. 11 is a perspective view of the air passage 6. FIG. FIG. 11(a) is a perspective view of the air duct 6 seen from above the right rear surface, and FIG. 11(b) is a perspective view of the air duct 6 seen from the upper right side. FIG. 12 is a cross-sectional view of the drying apparatus 1 taken along line AA shown in the front view of FIG.

As shown in FIG. 9, the blower section 9 has a motor 91 and a fan 92b. The motor 91 is fixed to one side of the fixing portion 93 . A through hole 93a is formed substantially in the center of the fixed portion 93 (see FIG. 4). The motor 91 is fixed to the fixing portion 93 with the rotary shaft 91a (see the left side view in FIG. 9 and FIG. 4) inserted into the through hole 93a. When the motor 91 is fixed to the fixed portion 93 , the rotating shaft 91 a protrudes to the other side of the fixed portion 93 . Further, the motor 91 is fixed to the fixing portion 93 and is also fixed to the partition plate 331 . As shown in the plan view and the bottom view in FIG. 9, the area defined by the partition plate 331 and to which the motor 91 is not attached serves as the cord storage section 314 .

The fan 92 b is arranged on the other surface side of the fixing portion 93 and fixed to the rotating shaft 91 a of the motor 91 . Thereby, the fan 92b can rotate according to rotation of the rotating shaft 91a. The fan 92b is rotatably housed in the fan case 92a. The fan case 92a includes a fan placement portion 911 formed in a shape that follows the outer shape of the fan 92b and in which the fan 92b is arranged, and a portion of the side wall of the fan placement portion 911 that extends from the fan case 92a and discharges air to the air passage 6. and an exhaust portion 912 . The fan case 92 a also has an opening 913 that opens the fan placement portion 911 on the side opposite to the surface facing the fixing portion 93 . The opening 913 serves as a main intake port among the intake ports for sucking air into the fan case 92a from the surroundings. The fan case 92a is arranged with an opening 913 serving as a main air intake facing the second side wall 31b (see FIG. 8) where no air intake is formed.

The rotating shaft of the fan 92b and the rotating shaft 91a of the motor 91 are arranged orthogonal to the first side wall 31a (see FIG. 8). The fan 92b is, for example, a sirocco fan. The air sucked into the fan case 92a flows perpendicularly to the rotational axis of the fan 92b, that is, in the centrifugal direction. As the fan 92b rotates, an air current is generated in the fan case 92a in the direction of rotation of the fan 92b. This airflow is generated between the fan 92 b and the fan arrangement portion 911 and is generated toward the air passage 6 via the exhaust portion 912 .

As shown in the left side view of FIG. 9, the motor is projected from the direction of the rotation axis of the fan 92b (that is, the rotation axis 91a of the motor 91) with the fan 92b and the motor 91 fixed to the fixing portion 93. 91 is arranged so as to fit within the outer shape of the fan case 92a. Similarly, the cord housing portion 314 is also substantially within the outer shape of the fan case 92a when viewed from the direction of the rotating shaft 91a of the motor 91 of the fan 92b with the fan 92b and the motor 91 fixed to the fixing portion 93. positioned to fit. In addition, the motor 91 and the cord housing portion 314 are arranged side by side in a projection view from the direction of the rotating shaft 91a with the fan 92b and the motor 91 fixed to the fixing portion 93. FIG. The fan 92b is attached to the motor 91 with the rotation axis of the fan 92b aligned with the rotation axis 91a of the motor 91 . Also, the height of the motor 91 is shorter than the diameter of the fan 92b. Therefore, when the fan 92b is attached to the motor 91, a space is created below the motor 91 in a projection view from the direction of the rotating shaft 91a. In this embodiment, this space created below the motor 91 is used as the cord housing portion 314 . As a result, the drying device 1 can utilize the storage space 300 of the housing 3 without waste, so that the size of the drying device 1 can be reduced.

As shown in FIG. 9, the air passage 6 is arranged adjacent to the exhaust portion 912 of the fan case 92a. The air passage 6 is arranged downstream of the fan case 92a. The air passage 6 has a heating portion 61 and an air passage 62 . The heating section 61 is provided adjacent to the fan case 92a. The ventilation path 62 is arranged between the heating portion 61 and the outlet 317 (see FIG. 3) formed in the housing 3 . As shown in the plan view of FIG. 9, the cord housing portion 314 is not arranged on the line where the air passage 6 is attached to the exhaust portion 912 of the fan case 92a. The drying device 1 prevents the outer shape of the housing 3 from being elongated in the direction of this line by arranging the cord storage part 314 next to this line on which the air passage 6 and the exhaust part 912 of the fan case 92a are arranged. Miniaturization is planned.

Next, the configuration of the air duct 6 will be described more specifically. As shown in FIGS. 10 and 11, the heating unit 61 has a cylindrical heater case 612 and a heater 611 arranged in an internal space 61a of the heater case 612 (see FIGS. 11B and 4). are doing. An exposed surface 612a, which is a part of the outer surface of the heater case 612, is exposed through an opening 319 (see FIG. 3) formed in the back surface 31c of the housing 3. As shown in FIG. The exposed surface 612a has a rectangular outer edge, and the opening 319 also has a rectangular outer edge. The exposed surface 612 a is formed one size smaller than the opening 319 . Therefore, the exposed surface 612a is arranged with almost no space between it and the opening 319, and can be exposed to the outside.

The heater 611 is arranged adjacent to the fan case 92a in a direction orthogonal to the rotational axis of the fan 92b. The heater 611 is arranged adjacent to the exhaust port of the fan case 92a through which the air sucked into the fan case 92a is exhausted. The heater 611 is arranged in the internal space 61 a of the heater case 612 . The heater 611 has, for example, a plurality (two in this example) of first and second heaters 611a and 611b (see FIG. 5). The first and second heaters 611a and 611b are composed of PTC (Positive Temperature Coefficient) heaters. The first and second heaters 611a, 611b can operate independently. The first and second heaters 611a and 611b are arranged side by side in close contact so as to be orthogonal to the blowing direction of the air flowing through the inner space 61a of the heater case 612 . The drying device 1 controls the temperature of the air discharged from the hose 5 by changing the number of first and second heaters 611a and 611b that supply current. For example, when setting the air temperature to a high temperature, current is supplied to both the first and second heaters 611a and 611b, and when setting the air temperature to a low temperature, the first and second heaters 611a , 611b. Furthermore, the drying apparatus 1 does not supply current to any of the first and second heaters 611a and 611b when only air is blown from the hose 5 without increasing the temperature of the taken air. The heater 611 is controlled by a controller 71 provided on the main circuit board 350 . The operation circuit board 323 (see FIG. 4) outputs to the main circuit board 350 information based on the set temperature set by the user using the operation panel 321 (see FIG. 4). The control unit 71 (see FIG. 5) provided on the main circuit board 350 determines the heater to be driven among the first and second heaters 611a and 611b based on the information input from the operation circuit board 323, and determines the heater to be driven. The heater 611 is driven so that the temperature of the air discharged from 5 becomes the set value.

The internal space 61a of the heater case 612 serves as a flow path for sending the air exhausted from the fan case 92a to the downstream ventilation path 62 . Heater 611 has a plurality of narrow gaps. The air blown from the fan case 9 enters the internal space 61a, flows through a plurality of narrow gaps provided in the heater 611, and is heated by at least one of the first and second heaters 611a and 611b to produce warm air. Then, it passes through the heater 611 and enters the internal space 62 a of the ventilation passage 62 .

Further, as shown in FIG. 11B, the heating unit 61 includes a thermal fuse 613 and a thermostat 614 provided inside the heater case 612 on one side perpendicular to the exposed surface 612a. Thermostat 614 has a bimetal and is on/off controlled mechanically. The drying apparatus 1 is temperature controlled by a thermostat 614 and a thermal fuse 613 in addition to temperature control by the thermistors 81 and 621 . The thermostat 614 is turned off when the temperature of the heating portion 61 reaches or exceeds a predetermined value on the high temperature side. Since the thermostat 614 is connected in series with the heater 611 (see FIG. 5), it cuts off the current supply from the main circuit board 350 to the heater 611 when it is turned off. As a result, the drying device 1 prevents the heating section 61 from overheating. Further, the thermostat 614 is turned on when the temperature of the heating portion 61 becomes equal to or lower than a predetermined value on the low temperature side, and restarts the supply of current from the main circuit board 350 to the heater 611 . As a result, the drying device 1 prevents the temperature of the hot air discharged from the hose 5 from dropping more than necessary.

The thermal fuse 613 is fused, for example, when the temperature of the heating portion 61 reaches or exceeds a predetermined value. Since the thermal fuse 613 is connected in series with the heater 611 (see FIG. 5), it cuts off the current supply from the main circuit board 350 to the heater 611 when blown. The thermal fuse 613 remains fused even if the temperature of the heating portion 61 becomes lower than a predetermined value after being fused. For this reason, the temperature at which the thermal fuse 613 melts is set higher than the predetermined value for temperature comparison in the thermostat 614 and the thermistors 81 and 621 . The thermal fuse 613 is the final protective means for preventing the heating section 61 from overheating.

As shown in FIGS. 10 and 11, the air passage 62 into which the hot air generated by the heating section 61 flows has a cylindrical shape. An internal space 62 a of the ventilation path 62 communicates with an internal space 61 a of the heating section 61 . As described above, the thermistor 621 is provided in the internal space 62 a of the ventilation passage 62 to detect the temperature of the hot air blown from the heating section 61 . The downstream open end of the ventilation passage 62 is formed in substantially the same shape as the ejection port 317 so that it can be inserted into the ejection port 317 .

As shown in FIG. 12 , the upstream end of the heating unit 61 is connected to the fan case 92 a , the upstream end of the ventilation passage 62 is connected to the downstream end of the heating unit 61 , and attached to the discharge port 317 . The downstream end of the ventilation passage 62 is connected to the end of the hose attachment member 52 of the hose 5 . The exhaust portion 912 of the fan case 92a, the heating portion 61, the ventilation passage 62, and the hose attachment member 52 are arranged in a straight line. By extending the bending member 51 along this straight line, the exhaust portion 912 of the fan case 92a and the outlet of the nozzle 54 (see FIG. 2) are arranged on a straight line. As a result, the air blown from the fan 92b and discharged from the discharge port 317 can flow out of the nozzle 54 without colliding with the inner wall surface of the hose 5 or the like. For this reason, the drying device 1 can prevent loss of wind pressure of the air discharged from the discharge port 317 . By connecting the fan case 92a, the heating unit 61, the ventilation passage 62, and the hose attachment member 52, the internal space 92c of the fan case 92a, the internal space 61a of the heating unit 61, and the internal space 62a of the ventilation passage 62 are defined. communicate. As a result, the air blown from the fan case 92 a becomes warm air and can be circulated inside the hose 5 .

Next, the structure of the hose 5 will be described more specifically with reference to FIGS. 1 to 12 and FIGS. 13 to 16. FIG. FIG. 13 is a perspective view of the drying apparatus 1 with the hose attachment member 52 removed, as seen from the rear side. FIG. 14 is a cross-sectional view of the drying apparatus 1 taken along lines BB and CC shown in the front view of FIG. 14(a) is a cross-sectional view of the drying apparatus 1 cut along the line BB, and FIG. 14(b) is a cross-sectional view of the drying apparatus 1 cut along the line CC. FIG. 15 is an orthographic view of the nozzle 54 with the aroma case 55 inserted. A plan view of the nozzle 54 is shown in the upper part of FIG. 15, a front view, a right side view and a rear view of the nozzle 54 are shown in this order from the left in the middle part of FIG. A bottom view of nozzle 54 is shown. 15, the illustration of the left side view of the nozzle 54 is omitted. In addition, in FIG. 15, the hot air discharge side is the front of the nozzle 54 . 16 is a perspective view of the aroma case 55 inserted into the nozzle 54. FIG. 16(a) shows a state in which the aroma case 55 is inserted into the nozzle 54, and FIG. 16(b) shows a state in which the aroma case 55 is unfolded.

As shown in FIG. 13, the filter 56 attached to the hose 5 is arranged in a cylindrical portion 512 provided at the end of the bending member 51 on the hose attachment member 52 side. The filter 56 is arranged on the upstream side of the cylindrical portion 512, that is, on the hot air inflow side. The filter 56 is provided between the air passage 6 and the other end of the hose 5 (on the hose tip member 53 side). As shown in FIGS. 13 and 14(a), the filter 56 is formed in a mesh shape in which a plurality of elongated members are crossed.

As shown in FIG. 14(a), the hose attachment member 52 and the hose tip member 53 are formed in a tubular shape. Further, the bending member 51 is also formed in a tubular shape. The internal space 52a of the hose attachment member 52, the internal space 51a of the bending member 51, and the internal space 53a of the hose tip member 53 communicate with each other. Therefore, the hot air flowing into the hose mounting member 52 from the discharge port 317 flows through the internal space 52a of the hose mounting member 52, the internal space 51a of the bending member 51, and the internal space 53a of the hose mounting member 52, and flows through the hose tip member. It is discharged from a nozzle 54 provided at the end of 53 . Further, the hose attachment member 52 has a side surface on the side of the hose accommodating portion 8 and a discharge port 521 provided on a side surface opposite to this side surface. The ejection port 521 is composed of a plurality of rectangular through holes (see FIGS. 1 and 2). The drying apparatus 1 discharges part of the hot air that has flowed into the hose mounting member 52 from the discharge port 317 through the discharge port 521, thereby blowing the hot air onto the object to be dried placed near the hose mounting member 52 to dry the object. Objects can be dried.

As shown in FIG. 14(b), the hose 5 includes a magnet 531 provided on the hose tip member 53 and an inner side of the housing 3 facing the magnet 531 when the hose tip member 53 is housed in the hose housing portion 8. and a ferromagnetic body 326 provided at the position of . The drying device 1 can maintain the state in which the hose tip member 53 is housed in the hose housing portion 8 with a simple configuration of the magnet 531 and the ferromagnetic material 326 . The drying apparatus 1 is provided at a position inside the housing 3 facing the ferromagnetic body provided in the hose tip member 53 and the ferromagnetic body when the hose tip member 53 is housed in the hose housing portion 8. and magnets. An insertion portion 543 of the nozzle 54, which will be described later, is provided at a position that bisects the cross section of the hose 5 when viewed from the discharge side. More specifically, the insertion portion 543 is provided at a position that bisects the cross section of the hose tip member 53 that is a part of the hose 5 when viewed from the discharge side.

As shown in FIG. 15, the nozzle 54 provided on the hose tip member 53 has an opening 541 into which an aroma case 55 containing either an aromatic agent or a deodorant is inserted, and an insertion opening 541. and a portion 543 . The nozzle 54 has an opening 541 and an insertion portion 543 on the hot air discharge side blown from the discharge port 317 (see FIG. 3). Since the nozzle 54 has an opening 541 and an insertion portion 543 facing the discharge side, the aroma case 55 can be attached and detached without removing the nozzle 54 from the hose tip member 53 . The nozzle 54 has a mounting portion 544 formed in a shape following the shape of the opening of the hose tip member 53 when viewed from the front (that is, viewed from the hot air discharge side). The nozzle 54 is attached to the discharge-side end of the hose tip member 53 by an attachment portion 544 .

The opening 541 opens so that the aroma case 55 can be inserted from the discharge side. The opening 541 has a shape in which the width at the center of the nozzle 54 is the narrowest and the width at both ends is wide when viewed from the front. The insertion portion 543 is provided from the opening portion 541 toward the mounting portion 544 side. The insertion portion 543 is provided in a circular region having a diameter that includes a central portion where the width of the opening 541 is the narrowest and a length that is approximately the same as the width of the aroma case 55 . The insertion portion 543 has a first clamping member 543a provided substantially in the center of the opening 541, and a pair of second clamping members 543b arranged to face each other with the first clamping member 543a interposed therebetween. The first holding member 543a has a U-shape extending toward the mounting portion 544 side. The second holding member 543b is provided substantially on the circumference of the circular region in which the insertion portion 543 is provided. The second holding member 543b is composed of a U-shaped member extending toward the mounting portion 544 and a rectangular parallelepiped member adjacent to the U-shaped member. This rectangular parallelepiped member extends toward the mounting portion 544, has a width substantially equal to the gap between the U-shaped members, and is arranged adjacent to this gap. A groove surrounded on three sides by a U-shaped member and a rectangular parallelepiped member is formed in the second holding member 543b.

The gap between the U-shaped members of the first and second holding members 543 a and 543 b is formed shorter than the thickness of the aroma case 55 . Also, the lengths of the first and second holding members 543 a and 543 b are longer than the length of the aroma case 55 . Furthermore, the first and second holding members 543a and 543b are made of resin and have elasticity. Therefore, as shown in FIG. 15, when the aroma case 55 is inserted into the insertion portion 543, the longitudinal central portion of the aroma case 55 is sandwiched between the first clamping members 543a, and both longitudinal ends of the aroma case 55 are held. is inserted into the groove of the second holding member 543b. In this manner, the aroma case 55 is held between the first and second holding members 543a and 543b, and is held within the insertion portion 543 unless a certain amount of external force is applied. Further, the insertion portion 543 can hold the aroma case 55 against the wind pressure of the air discharged from the hose 5 .

The nozzle 54 has notches 542 provided on the outer peripheral edge of the nozzle 54 facing each other at both ends of the insertion portion 543 . The notch 542 constitutes both ends of the opening 541 . The shape of the notch 542 gradually becomes larger in the direction in which the aroma case 55 is inserted, and then becomes smaller. That is, as shown in the right side view of FIG. 15, the notch 542 has an arc shape. The notch portion 542 is used when the aroma case 55 is attached and detached. For example, when attaching the aroma case 55 to the nozzle 54 , when the user pinches both ends of the aroma case 55 and inserts the aroma case 55 into the insertion portion 543 , the user's fingers are inserted into the notch portion 542 . Because of the position, the aroma case 55 can be smoothly inserted into the insertion portion 543 . As shown in the right side view of FIG. 15, part of the end of the aroma case 55 is exposed through the notch 542 . Therefore, for example, when removing the aroma case 55 from the nozzle 54, the user inserts his or her finger into the notch 542 and pulls the aroma case 55 over approximately one-third of the side surface of the aroma case 55 extending in the insertion direction. can be picked. As a result, the user can apply a stronger force to the aroma case 55 from both ends than the force applied to the aroma case 55 from the insertion portion 543 , so that the aroma case 55 can be easily removed from the nozzle 54 . can.

As shown in FIG. 16(a), the aroma case 55 has a thin plate shape. The aroma case 55 has a first box portion 551 and a second box portion 552 facing the first box portion 551 . In addition, the aroma case 55 has a bent portion 553 on one of its short sides. The first and second box portions 551 and 552 are formed to be unfoldable by a bent portion 553 . As shown in FIG. 16(b), the aroma case 55 rotates around the bent portion 553 as a rotation axis.
The first box portion 551 and the second box portion 554 can be opened. The first box portion 551 and the second box portion 554 have a box shape with opening ends on opposite sides. Therefore, when the first box portion 551 and the second box portion 554 are closed, a space is formed between the first box portion 551 and the second box portion 554 . The aroma case 55 holds a volatile component-containing member (for example, a sheet impregnated with an aromatic agent or a deodorant) in this space. A plurality of through holes 554 are formed in the surfaces of the first box portion 551 and the second box portion 554 . Therefore, the volatile component of the volatile component containing member held in the aroma case 55 is released to the outside through the through hole 554 . The drying device 1 blows the volatile components released from the aroma case 55 onto the object to be dried by placing them on warm air blown from the hose 5. - 特許庁For example, when the volatile component is a component of an aromatic agent or a deodorant, the drying apparatus 1 can add the fragrance of the aromatic agent to the object to be dried or deodorize the object to be dried.

Next, the operation and mode of use of the drying apparatus 1 will be described with reference to FIGS. 1 to 16 and FIGS. 17 and 18. FIG. FIG. 17 is a diagram for explaining the flow of air during operation of the drying apparatus 1. FIG. The drying apparatus 1 is used with the bending member 51 of the hose 5 extended during operation, but FIG. 17 shows the bending member 51 bent (the storage state of the drying apparatus 1). 18A and 18B are diagrams illustrating an example of a usage state of the drying device 1. FIG. 18(a) is a perspective view of an example of the usage of the drying device 1, and FIG. 18(b) is a view of the example of the usage of the drying device 1 from the side of the second side wall 31b of the drying device 1. It is a figure which shows.

When the user operates the operation panel 321 to turn on the drying apparatus 1 , the main circuit board 350 drives the motor 91 . As a result, the motor 91 operates and the fan 92 b rotates, so that air is drawn into the housing space 300 of the housing 3 from the outside through the air inlet 21 , the air inlet 312 and the air inlet 313 . As described above, the opening 913, which is the main air intake of the fan case 92a, is not the first side wall 31a in which the air intake 21 and the air intake 312 are formed, or the bottom surface 31e in which the air intake 313 is formed, but the second air intake. It is arranged to face the side wall 31b. The fan case 92a is arranged with a gap between it and the second side wall 31b. Therefore, a gap 310 is formed between the fan case 92a and the second side wall 31b. The second side wall 31b does not have a through hole such as an intake port, and the only through hole 311b (see FIG. 7) formed in the second side wall 31b is closed with a screw (not shown). there is Therefore, it can be considered that the second side wall 31 b does not have a through hole that communicates the outside of the housing 3 with the housing space 300 . Therefore, the air entering the accommodation space 300 of the housing 3 through the air inlet 21, the air inlet 312, and the air inlet 313 cannot enter the fan case 92a through the opening 913 unless it passes through the gap 310. . Moreover, the gap 310 is a space narrower than the space in which the main circuit board 350, the air duct 6, and the like are arranged. Therefore, the air sucked into the accommodation space 300 flows into the gap 310 with an increased flow velocity from the space in which the blower passage 6 is arranged. As a result, compared to the suction force into the fan case 92a due to only the rotation of the fan 92b, the suction force into the fan case 92a in this embodiment is due to the flow into the gap 310 in addition to the rotation of the fan 92b. , the air that has entered the housing space 300 can be more efficiently sucked into the fan case 92a.

At this time, as shown in FIG. 17, the air entering the housing space 300 of the housing 3 from the intake ports 21 and 312 flows through the main circuit board 350, the heating unit 61, and the fan 92b in this order. A flow path P1 is formed. From a different point of view, the drying apparatus 1 has a ventilation path through which the air that has entered the housing space 300 of the housing 3 from the air inlets 21 and 312 flows through the main circuit board 350, the heating unit 61, the gap 310, and the fan 92b in this order. It has The drying apparatus 1 has a gap 310 in this ventilation passage. Further, in the housing space 300 of the housing 3, there is also formed a flow path P2 in which the air entering the housing space 300 of the housing 3 from the air inlets 21 and 312 flows directly from the motor 91 side to the fan case 92a instead of the flow path P1. be done. Furthermore, in the accommodation space 300 of the housing 3, the air entering the accommodation space 300 of the housing 3 from the intake port 313 flows from the side surface of the fan case 92a toward the second side wall 31b into the gap 310 and flows to the fan 92b. A flow path P3 is also formed. Although not shown, the air entering the housing space 300 of the housing 3 from the intake port 313 flows through the main circuit board 350, the heating unit 61, and the fan 92b in this order. A path and a flow path are also formed in which the air entering the accommodation space 300 of the housing 3 from the air inlet 313 flows directly from the motor 91 side to the fan 92b. Since the drying device 1 has the gap 310 , a flow path is formed in which the air in the accommodation space 300 rotates halfway when viewed from the opening end side of the main body 31 , and the air in the accommodation space 300 is forced to flow. Stir to prevent air retention.

In this manner, the drying apparatus 1 arranges the fan case 92a close to the second side wall 31b with the opening 913, which is the main intake port, facing the second side wall 31b having no through hole. there is Thereby, the drying apparatus 1 can generate the flow path P<b>1 in the housing space 300 of the housing 3 and prevent air from staying in the housing space 300 . Although the temperature of the air near the heating portion 61 rises, the flow path P1 is formed including the space above the heating portion 61, so the air near the heating portion 61 is sucked again by the fan 92b. Therefore, the high-temperature air in the vicinity of the heating portion 61 does not flow toward the main circuit board 350, so that the temperature of the main circuit board 350 is prevented from rising. Furthermore, since the flow path P1 is formed including the space above the main circuit board 350, the main circuit board 350 is cooled by the air flowing through the flow path P1, thereby preventing the temperature from rising.

The air that has entered the fan case 92a from the flow paths P1, P2, P3, etc. enters the hose 5 through the flow path P4 that flows through the fan case 92a, the blower path 6, and the hose 5 in this order. Since the flow path P4 includes the heating portion 61, the air entering the hose 5 is warm air having a temperature according to the set value. This hot air is discharged outside the drying apparatus 1 from a nozzle 54 (not shown in FIG. 17) provided at the end of the hose tip member 53 . When the aroma case 55 is inserted into the nozzle 54 , the hot air discharged from the nozzle 54 contains the aromatic and deodorant provided in the aroma case 55 . The drying apparatus 1 automatically stops after discharging warm air to the object to be dried for the drying time set by the user by operating the operation panel 321 .

As shown in FIG. 18, when drying a futon, for example, the drying device 1 is placed on the futon 500, which is the surface on which it is placed, with the rear portion 31c facing the futon. As shown in FIG. 18(b), the hose 5 is spread over the mattress 500 while the bending member 51 is stretched. Since the outer shape of the hose tip member 53 has a prismatic shape instead of a cylindrical shape, it is difficult to move the hose 5 in a deployed state. The comforter 501 is put on the mattress while being sandwiched between the holding part 330 and the space part 4 formed between the hose 5 . The length of the gripping portion 330 in the same direction as the extension direction of the hose attachment member 52 is shorter than the length of the hose attachment member 52 in the same direction. Therefore, the drying device 1 makes it easy to insert the comforter 501 into the space 4 . Further, since the space 4 serves as a guideline for the placement position of the comforter 501, the user can set the comforter 501 on the drying device 1 with the operation panel 321 and the LED display window 322 exposed. As a result, the user can easily set the temperature using the operation panel 321 and confirm the operating state of the drying apparatus 1 using the LED display window 322 .

In the drying apparatus 1, the rotating shaft of the fan 92b, that is, the rotating shaft 91a of the motor 91, is arranged parallel to the surface on which the front panel 32 and the rear portion 31c spread, so that the air intake is located on the front panel 32 and the rear portion 31c. Instead, it can be formed on the first side wall 31a or the bottom surface portion 31e. Therefore, even if the drying apparatus 1 is placed with the rear portion 31c facing the placement surface of the futon 500 or the like, the intake ports 312 and 313 are not blocked, so air can be sucked in smoothly.

When the operation of the drying apparatus 1 is started in the state shown in FIG. Drying begins. The hot air discharged from the nozzle 54 slightly lifts the comforter 501 . As a result, a space is formed between the mattress 500 and the comforter 501 in which the warm air discharged from the nozzles 54 stays. The mattress 500 and the comforter 501 are dried by the warm air staying in this space. The drying apparatus 1 improves the air intake ratio of the fan 92b by devising the arrangement location of the fan case 92a, so that the output of hot air discharged from the nozzle 54 is improved.

An exposed surface 612a (see FIG. 1) of the heater case 612 is exposed to the back surface portion 31c. The exposed surface 612 a is in contact with the mattress 500 . The temperature of the heater case 612 rises with the operation of the heater 611, and the temperature of the exposed surface 612a forming part of the heater case 612 also rises. Therefore, the drying apparatus 1 can transfer heat from the exposed surface 612 a to the mattress 500 during operation of the drying apparatus 1 to dry a certain area of the mattress 500 located near the drying apparatus 1 .

A gap corresponding to the height of the hose attachment member 52 is generated between the mattress 500 and the comforter 501 in the vicinity of the drying device 1 . By the way, the side surface of the hose attachment member 52 is formed with a discharge port 521 that opens toward this gap. Therefore, the hot air discharged from the housing 3 is also discharged from the discharge port 521 in addition to the nozzle 54 . The warm air discharged from the discharge port 521 dries the mattress 500 and the comforter 501 in the vicinity of the hose attachment member 52 . Also, this warm air is blown out in the direction in which the short sides of the comforter 501 extend. Therefore, this hot air is discharged toward the gap formed by the height of the hose attachment member 52 between the mattress 500 and the comforter 501, and the hot air from the outside of the mattress 500 and the comforter 501 and the nozzle 54. It functions as an air shower that prevents the space formed between the mattress 500 and the comforter 501 from communicating with each other. Thereby, the drying device 1 can prevent air from flowing in and out between the mattress 500 and the comforter 501 and the outside, and can prevent the temperature between the mattress 500 and the comforter 501 from decreasing during drying. .

In this way, the drying device 1 can discharge high-output warm air from the nozzle 54 between the mattress 500 and the comforter 501, and heat a certain area of the mattress 500 located near the drying device 1 to the heat of the exposed surface 612a. The hot air discharged from the outlet 521 formed in the hose mounting member 52 dries the mattress 500 and the comforter 501 near the hose mounting member 52, and also dries between the mattress 500 and the comforter 501. It is possible to prevent the inflow and outflow of air to and from the outside. As a result, the drying device 1 can efficiently dry the mattress 500 and the comforter 501, which are objects to be dried, without using an air mat used in a conventional futon dryer.

When the object to be dried is, for example, shoes or clothes, the nozzle 54 is set toward the object to be dried with the drying device 1 standing on the legs 33, and warm air is blown directly to dry the object to be dried. Let

As described above, the drying device 1 according to the present embodiment has the cord housing portion 314 formed in the direction of the fan case 92a from the opening 314a formed in the first side wall 31a and arranged side by side with the motor 91. ing. The cord housing portion 314 is provided in an empty space created by the motor 91 pivotally supporting the fan 92b housed in the fan case 92a. Therefore, according to the present embodiment, the storage space 300 of the housing 3 is effectively used, so that the size of the drying apparatus 1 can be reduced.

The drying device 1 has a gap 310 formed between the fan case 92a and the second side wall 31b that does not have a through hole such as an air intake. Further, the fan case 92a is arranged with the opening 913 serving as the main intake port directed toward the second side wall 31b. As a result, the air entering the housing space 300 of the housing 3 from the intake ports 21 and 312 flows through the main circuit board 350, the heating unit 61, and the fan 92b in this order. is formed. Thereby, the drying apparatus 1 can prevent air from staying in the housing space 300 . Further, the heat generated by the heating unit 61 is sent to the fan case 92a by the air flowing through the flow path P1. It becomes difficult for the heat generated in to be transferred. Further, the main circuit board 350 is air-cooled by the air flowing through the flow path P1. Thereby, the drying device 1 can prevent the temperature of the main circuit board 350 from rising.

The drying apparatus 1 has a hose accommodating portion 8 on the rear side of the housing 3 and next to the discharge port 317 to which one end of the hose 5 is attached. The drying apparatus 1 utilizes the bendability of the bending member 51 of the hose 5, and accommodates the hose tip member 53 on the other end side in the hose accommodating portion 8, so that the hose attachment member 52 and the hose tip member 53 are provided at one end. can be stored side by side. As a result, the size of the drying device 1 can be reduced when it is housed. Further, the hose tip member 53 can be accommodated in the hose accommodation portion 8 simply by attaching the magnet provided in the hose tip member 53 to the ferromagnetic material provided inside the housing 3 near the hose accommodation portion 8 . In this way, with a simple configuration in which the magnet 531 and the ferromagnetic material 326 are attached by the magnetic force of the magnet 531, the drying apparatus 1 can be changed from the use state to the storage state, thereby simplifying the storage work. Moreover, the drying apparatus 1 does not have a complicated structure that deforms the housing for storage. Thus, according to this embodiment, the weight of the drying device 1 can be reduced.

The drying apparatus 1 includes a resistance value measuring circuit that measures the resistance value of the temperature sensor when the power cord is inserted, and a resistance value measuring circuit that prevents the drying apparatus 1 from operating when the resistance value measured by the resistance value measuring circuit exceeds a predetermined threshold value. and a control unit for controlling. As a result, the drying apparatus 1 can detect an abnormality (for example, a temperature sensor failure) immediately before the start of operation, thereby preventing an abnormal operation.

The drying device 1 has a configuration in which the exposed surface 612a of the heater case 612 is exposed at the rear surface portion 31c. The temperature of the exposed surface 612a rises during operation of the drying device 1 . For this reason, the drying device 1 dries the object to be dried, which is arranged near the housing 3 which is arranged relatively far from the nozzle 54 of the hose 5 through which hot air is discharged, using the temperature of the exposed surface 612a. be able to.

The drying apparatus 1 has a nozzle 54 provided in the hose tip member 53 having an opening 541 into which the aroma case 55 is inserted and an insertion portion 543 having the opening 541 . The nozzle 54 has an opening portion 541 and an insertion portion 543 facing the discharge side. Thus, according to this embodiment, the aroma case 55 can be attached and detached without removing the nozzle 54 from the hose tip member 53, so that the attachment and detachment work of the aroma case 55 is simple and easy.

The drying apparatus 1 has a grip portion 330 extending from the upper surface portion 31d in the same direction as the extension direction of the hose attachment member 52, and a space portion 4 formed between the grip portion 330 and the hose attachment member 52. ing. The space 4 serves as a place for arranging a comforter, which is an example of an object to be dried, and serves as a guideline for the arrangement position of the comforter. As a result, the drying device 1 can prevent the user from operating the drying device 1 while the comforter is erroneously hung on the housing 3 .

The drying device 1 has an inclination sensor 13 for detecting the installation state of the housing 3 and an operation switch section 73 for stopping or continuing the operation of the drying device 1 depending on the installation state of the housing 3 . Therefore, the drying apparatus 1 can stop operating when the intake port 312 faces the mounting surface, and can continue operating when the intake port 313 faces the mounting surface. As a result, the drying apparatus 1 can stop the operation when there is a possibility that the device (for example, the motor 91) housed in the housing 3 will over-operate, thereby preventing damage to the device within the housing 3. .

Next, a drying apparatus 1 according to a modified example of this embodiment will be described with reference to FIGS. 19 to 21. FIG. The drying apparatus 1 according to this modification is characterized in that the shape of the hose accommodating portion is different from that of the drying apparatus 1 according to the above-described embodiment. Hereinafter, constituent elements having the same functions and actions as those of the drying apparatus 1 according to the above-described embodiment are denoted by the same reference numerals, and descriptions thereof are omitted. FIG. 19 is a perspective view of the drying device 1 according to this modification as viewed from above the left rear surface. FIG. 20 is a rear view of the drying device 1 according to this modification. FIG. 21 is an enlarged view showing the vicinity of the hose accommodating portion 80 provided in the drying apparatus 1 according to this modified example within the frame α.

As shown in FIGS. 19 to 21, in the drying device 1 according to this modification, the tip of the hose tip member 53 (an example of the other end of the hose) of the hose 5 is formed on the upper surface 80d of the hose housing portion 80 facing the tip. It has a protrusion 801 . The protrusion 801 is formed so as to protrude from the upper surface 80d. The projecting portion 801 has a shape extending parallel to the side surface 80 a of the hose housing portion 80 from the back surface 80 d of the hose housing portion 80 . The upper surface 80d is a surface parallel to the surface of the upper surface portion 31d on which the outlet 317 is formed, the rear surface 80c is a surface parallel to the surface of the rear surface portion 31c on which the opening 612a is formed, and the side surface 80a is: It is a plane parallel to the first side wall 31a.
