[0008] <Embodiment>

[0009] 1. Overview The schematic structure of the drying device X according to the embodiment will be described with reference to FIGS. The drying device X dries items to be dried, such as bedding, shoes, etc. The drying device X includes a main body 1 that houses a hot air supply unit 20 that supplies hot air, and a discharge unit 5 that discharges the hot air generated by the main body 1. The discharge part 5 includes a nozzle 51 and a hose 57 that can be curved (bent) and stretched. By bending the hose 57, the discharge part 5 can accommodate the nozzle 51 in the accommodation part 102 of the main body part 1, as shown in Fig. 1. When in use, the nozzle 51 is removed from the accommodation part 102, as shown in Fig. 2. Each part will be explained below.

[0010] 2. Main body As shown in FIG. 3, the main body 1 includes a hot air supply unit 20, a circuit unit 30, and an operation unit 40 housed in a housing 10. The main body 1 accommodates the nozzle 51 so that the hot air supply unit 20 and the nozzle 51 in the accommodated state are aligned, and the first support member 53 of the discharge unit 5 faces (is exposed to) the outside in the alignment direction. Specifically, in the accommodated state described above, a bend occurs between both ends of the hose 57, and the hose 57 extends to one side in a direction perpendicular to the alignment direction of the hot air supply unit 20 and the nozzle 51 in the accommodated state, turns back midway, and is bent so as to extend to the other side. In other words, the hose 57 is bent in a U-shape. Furthermore, since the housing 10 is open to the outside on the other side in the direction perpendicular to the alignment direction of the hot air supply unit 20 and the nozzle 51 in the accommodated state, when the hose 57 is accommodated in the housing 10 in the bent state described above, the hose 57 faces the outside.

[0011] (1) Housing The housing 10 accommodates the hot air supply unit 20, the circuit unit 30, the discharge section 5 when accommodated, and the board 43 with the operating means 41 and display means 42 of the operating unit 40 exposed to the outside of the housing 10. The housing 10 is box-shaped. The side on which the operation unit 40 is located is the front side, the side opposite to the front side is the rear side, the side from which the power cord 35 extends on the rear side is the bottom side, the side on which the hose 57 of the discharge unit 5 in the housed state can be seen (see FIG. 1(a)) is the left side, and the side on which the air intake 13a is located is the right side. As shown in FIG. 1, the housing 10 has a front wall 11, a rear wall 12, a right wall 13, an upper wall 14, and a lower wall 15, and has an opening 16 in the part corresponding to the left wall and in the part extending from the center (center toward the left) of the rear wall 12 to the right side, and the opening 16 is used to accommodate the discharge part 5 so that it can be inserted and removed. Here, a front wall 11, a rear wall 12, a right wall 13, and a bottom wall 15 are integrally formed to form the housing body. 3 to 5, the housing 10 has a partition wall 17 that divides the interior into an accommodation section 101 that accommodates (most of) the hot air supply unit 20, the circuit unit 30, and the operation unit 40, and an accommodation section 102 that accommodates the discharge section 5. For convenience, the accommodation section for the hot air supply unit 20, etc. will be referred to as the "unit accommodation section," and the accommodation section for the discharge section 5 will be referred to as the "discharge section accommodation section," to distinguish between the two accommodation sections.

[0012] The front wall 11 has through holes 11a for the operation means 41 and display means 42 of the operation unit 40, protrusions 11b for supporting the operation unit 40, boss screws 11c for fixing the operation unit 40, and the like. The rear wall 12 has a through-hole 12a for the power cord 35 and a latched portion 12b for latching the latching portion 528 of the nozzle 51 housed in the discharge portion housing portion 102 (see FIG. 1(b)). Note that the latched portion 12b is formed by a notch, as shown in FIG. The right wall 13 has an air intake 13a on one side in the front-to-rear direction and a pair of grooves 13b for holding a filter 103 that covers the air intake 13a. The hot air supply unit 20 and the nozzle 51 in the housed state are aligned in the front-to-rear direction, and the one side in the front-to-rear direction is the side on which the hot air supply unit 20 is arranged, which is the front side in this case. The housing 10 is open to the outside on the other side in the left-right direction that is perpendicular to the front-to-rear direction, which is the left side in this case. The upper wall 14 has an upper connecting portion (boss screw) 14a for connecting to the lower wall 15 (housing body), a partition wall portion 14b that separates the unit accommodating portion 101 from the discharge portion accommodating portion 102, and support portions 14c and 14d that position and support the hot air supply unit 20. The support portions 14c and 14d are formed of plate-like portions (ribs) that extend downward, with the support portion 14c supporting the blower means 21 side (right side in the left-right direction) of the hot air supply unit 20 and the support portion 14d supporting the mounting body 26 side (left side in the left-right direction) of the hot air supply unit 20. The lower wall 15 has a lower joining portion (boss hole) 15a for joining to the upper wall 14, support portions 15b and 15c for positioning and supporting the hot air supply unit 20, and a screw hole 15d (see FIG. 3) for fixing a holder 36 that covers the power cord 35 and holds the power cord 35. The support portions 15b and 15c are formed of plate-like portions (ribs) extending upward, with the support portion 15b supporting the blower means 21 side of the hot air supply unit 20 (the right side in the left-right direction) and the support portion 15c supporting the mounting body 26 side of the hot air supply unit 20 (the left side in the left-right direction). The boss screw, boss hole, and boss hole are composed of a boss and a screw hole (hole) or hole or holes formed in the boss. The partition wall 17 and the partition wall portion 14b of the upper wall 14 are provided in the front-to-rear direction to form the unit accommodating portion 101 on the front side and the discharge portion accommodating portion 102 on the rear side. In other words, the partition wall 17 and the partition wall portion 14b are provided at an intermediate position in the front-to-rear direction so as to be perpendicular to the front-to-rear direction. As a result, the unit accommodating portion 101 and the discharge portion accommodating portion 102 are provided side by side in the front-to-rear direction. To accommodate the hose 57 of the discharge portion 5 on the left side, the partition wall 17 and the partition wall portion 14b extend in the left-to-right direction from the right end position of the lower wall 15 in the left-to-right direction to a position shifted to the right by the length of the hose 57. The partition wall 17 has an intake port 17a on the right side in the left-right direction, and a pair of grooves (not shown) for holding a filter 104 that covers the intake port 17a.

[0013] (2) Hot air supply unit This will be explained using Figure 6. The hot air supply unit 20 includes at least a blower 21 having a fan 211 and a drive unit (motor) 213 that drives the fan 211, and a heating unit 22 that heats the air sent out by the blower 21. A plurality of blades serving as the fan 211 are provided around the rotation center line of the drive unit 213. In addition, sound absorbing material or vibration damping material may be wrapped around the periphery of the blower 21. The hot air supply unit 20 here includes a casing 23 that houses the air blowing means 21 and the heating means 22, a temperature sensor 24 (see FIG. 8) attached to the casing 23, a connector 25 for connecting to the hose 57, and an attachment 26 for attaching the connector 25 rotatably or fixedly (non-rotatably) to the casing 23. Note that the connector 25 is attached to the casing 23 after being connected to the hose 57, and therefore may be configured as a part of the hose 57.

[0014] (2-1) Casing 6 and 7, the casing 23 has a cylindrical shape that is long in the direction in which the rotation axis of the blower means 21 extends (hereinafter referred to as the "rotation axis direction"), and has a semi-cylindrical first member 231A and a second member 231B that are cut along the rotation axis direction (cut along an imaginary plane including the rotation axis). The first member 231A and the second member 231B are fixed (coupled) by, for example, screws or the like. The casing 23 has an inlet opening 232 through which air flows into the interior and an outlet opening 233 through which the air inside is discharged. Here, the inlet opening 232 is located on one side in the direction of the rotation axis, and the outlet opening 233 is located on the other side in the direction of the rotation axis. 7, in the configuration of the casing 23, when the casing 23 is configured with the first member 231A, the reference numeral for that component is given an "A," and when the casing 23 is configured with the second member 231B, the reference numeral for that component is given an "B." For example, in the inlet opening 232, the portion configured with the first member 231A is given an "232A," and the portion configured with the second member 231B is given an "232B." The casing 23 integrally supports the blower 21 and the heating means 22 between the inlet opening 232 and the outlet opening 233. Here, the heating means 22 is disposed closer to the outlet opening 233 than the inlet opening 232, and the blower 21 is disposed closer to the inlet opening 232 than the outlet opening 233. Preferably, the heating means 22 is disposed closer to the outlet opening 233 than the inlet opening 232, and the blower 21 is disposed closer to the inlet opening 232 than the outlet opening 233. This makes it easier to incorporate the casing 23 into the housing 10 in this embodiment than in the conventional technology in which a casing accommodating the blower and a casing accommodating the heating means are separately incorporated into the housing. For example, it is necessary to incorporate the casing into the housing so that no gaps are formed between the casings to prevent pressure loss. However, with the configuration of this embodiment, such a necessity does not arise when incorporating the casing 23 with respect to the blower 21 and the heating means 22. The inlet-side opening 232 is provided so that a center line passing through the center of the inlet-side opening 232 and extending in the direction of the rotation axis intersects with the opening plane of the outlet-side opening 233. This allows the air that flows in from the inlet-side opening 232 to flow smoothly (linearly) toward the outlet-side opening 233 and flow out from the outlet-side opening 233. Here, the inlet opening 232 and the outlet opening 233 have a circular shape. The opening area (diameter) of the outlet opening 233 is larger than the opening area (diameter) of the inlet opening 232. This makes it easier for the air sent out from the blower means 21 to hit a wide area of ​​the surface of the heating means 22, and therefore the air is sufficiently heated. In the casing 23, the portion supporting the blowing means 21 is cylindrical, and the portion supporting the heating means 22 is rectangular tubular. The casing 23 has an outlet 234 for leading out the connection terminal 223 of the heating means 22 to the outside, and a recess 235 for the temperature sensor 24 .

[0015] (2-2) Air blowing means This will be explained using Figure 6. The air blowing means 21 sends out air sucked from the air intake 13 a of the main body 1 toward the heating means 22 . The air blowing means 21 has a fan 211 on the outer periphery of a motor 213, and is formed as a unit (integrated). The motor 213 can be a DC motor (including brushed and brushless), an AC motor, or the like. Here, a brushless motor (BLDC) is used, which can achieve high output, energy savings, and the like. The motor 213 is arranged such that its rotation axis coincides with or is close to the central axis of the casing 23. The air blowing means 21 is disposed upstream in the rotational axis direction of the heating means 22. That is, the heating means 22, the air blowing means 21, the inlet opening 232 of the casing 23, and the intake port 13a of the housing 10 are arranged in this order from the downstream side in the rotational axis direction. The blower means 21 is disposed so that its rotation axis intersects with the opening plane of the outlet opening 233. This allows the blower means 21 to suck air through the suction port 213a and let the air flow out from the outlet opening 233 smoothly (linearly). The blower means 21 is disposed with its suction port 213a facing the inlet opening 232 of the casing 23. As a result, the air flowing in from the inlet opening 232 heads toward the suction port 213a of the blower means 21 through a short flow path. The radial width (diameter) of the drive unit (motor) 213 is smaller than the opening area of ​​the outlet opening 233. More specifically, when viewed from the rotation axis direction, the outer peripheral edge of the motor 213 is contained within the opening area of ​​the outlet opening 233. This makes it easier for negative pressure to be generated at the inlet opening 232, thereby improving suction performance.

[0016] (2-3) Heating means This will be explained using Figure 6. The heating means 22 includes a heater 221 and a connection terminal 223 for supplying power to the heater 221. When viewed from the direction of the rotation axis, the heater 221 has a rectangular shape or a shape similar thereto. The heater 221 may be a ceramic heater (PTC heater) or the like. 8(a), the temperature sensor 24 that detects the temperature of the heater 221 is fitted into a recess 235 of the casing 23, and the recess 235 is recessed toward the heater 221 in order to bring the heater 221 and the temperature sensor 24 closer to each other. Note that instead of the recess 235, the temperature sensor 24 may be exposed inside the casing 23 via a through-hole, in which case the temperature sensor 24 may be in contact with or spaced apart from the heater 221. Furthermore, various types of sensors such as a bimetal, a thermal fuse, or a thermistor may be used as the temperature sensor 24. As shown in Fig. 8(a), the heating means 22 is biased toward the temperature sensor 24 by an elastic body 27. This makes it easier for the temperature sensor 24 to approach the heater 221, enabling highly accurate temperature detection. Note that the temperature sensor 24 is supported by a support 241 attached to the casing 23, as shown in Fig. 8(b). The elastic body 27 is formed, for example, by bending a plate material. The elastic body 27 has at least a base portion 271 disposed in the casing 23 and an extension portion 273 that bends at an acute angle from the base portion 271 and extends toward the heater 221, and the extension portion 273 is configured to be elastically deformable in the biasing direction. The elastic body 27 is supported in a positioned state within the recess 236 of the casing 23. Specifically, the elastic body 27 is positioned by at least one of one end and the other end in the length direction and one end and the other end in the width direction of the base portion 271 abutting against an inner wall constituting the recess 236, and the elastic body 27 is housed with the extension portion 273 in contact with the heater 221. The temperature sensor 24 and the elastic body 27 face each other with the heater 221 sandwiched therebetween. The casing 23 also functions as a casing that supports the heater 221 by abutting against it.

[0017] (2-4) Connector As shown in Figures 6 and 7, the connector 25 has a cylindrical shape with a bottom, and has a spiral ridge 253 formed on the inner circumferential surface of a tubular portion 251, and a through hole 257 formed in a bottom portion 255. The end of the hose 57 is inserted into the tubular portion 251 and supported by the ridge 253. The through hole 257 in the bottom portion 255 provides a filtering function. The hose 57 may be detachable from the connector 25. The cylindrical portion 251 of the connector 25 is inserted into the cylindrical portion 237 at the other end (the outlet opening 233 side) of the casing 23 in the rotation axis direction.

[0018] (2-5) Mounting body 6, the mounting body 26 has a recess 263 with an opening 262 in a bottom 261, and a protruding portion 264 that protrudes outward from the edge of the recess 263 opposite the bottom 261. The mounting body 26 is fixed to the casing 23 with screws 269 (see FIG. 3) in a state in which the recess 263 covers the tubular portion 251 of the connecting body 25 that protrudes in the rotation axis direction from the casing 23, and the peripheral portion of the opening 262 of the bottom 261 abuts against the end face of the tubular portion 251 of the connecting body 25. The screw 269 is inserted through the fixing portion (through hole) 265 of the protruding portion 264 of the mounting body 26 and is screwed into the fixing portion (threaded hole or threaded hole) 238 of the casing 23.

[0019] (3) Circuit unit The circuit unit 30 receives power from a commercial power source via a power cord 35 and generates drive power for driving the hot air supply unit 20, the temperature sensor 24, the operation unit 40, and the like. 3 to 5, the circuit unit 30 includes a plurality of electronic components 31 and a board 32 on which the plurality of electronic components 31 are mounted, and is housed in the unit housing portion 101 of the housing 10. The board 32 is fixed to the bottom wall 15 using screws or the like. The circuit unit 30 is arranged between the hot air supply unit 20 and the lower wall 15, and as shown in Figure 4, electronic components 31 are arranged on both ends of the board 32 in the front-to-rear direction so as not to interfere with the hot air supply unit 20. Since the circuit unit 30 is disposed outside the casing 23 that houses the heating means 22, it is less susceptible to the heat of the heating means 22. Furthermore, since the circuit unit 30 is disposed on the flow path of the air sucked in from the air intake 17a of the partition wall 17 by the air blowing means 21, it is configured to be able to be cooled by the air flowing through the flow path.

[0020] (4) Operation unit As shown in Figures 3 to 5, the operation unit 40 has an operation means 41 and a display means 42 on a substrate 43, and the substrate 43 is fixed to the front wall 11 with the operation means 41 and the display means 42 fitted into the through holes 11a in the front wall 11. The operation unit 40 has an operation control section for operating at least the blowing means 21, in this case the hot air supply unit 20. The operation control section is made up of electronic components and is mounted on the substrate 43. As shown in FIGS. 4 and 5, the substrate 43 is provided in a state in which it stands upright from the lower wall 15 or along the front wall. When the drying device X is viewed from above, the nozzles 51 housed in the discharge part housing part 102, the air blowing means 21 or the hot air supply unit 20, and the operation control part (board 43) are lined up in this order in a direction (here, the front-to-back direction) perpendicular to the rotation axis direction of the hot air supply unit 20. This allows the space within the housing 10 to be used effectively, and the discharge part 5, the hot air supply unit 20, and the operation control part to be housed compactly.

[0021] 3.Discharge part As shown in Figure 2, the discharge unit 5 has a hose 57 connected to the main body 1 so as to communicate with the blowing means 21, and a nozzle 51 connected to the hose 57, and discharges the warm air generated in the main body 1 from the discharge port 511 of the nozzle 51. One end of the hose 57 is connected to the hot air supply unit 20, and the other end of the hose 57 is connected to the nozzle 51. The opening at one end of the hose 57 is an inlet to the hose 57, and the opening at the other end is an outlet from the hose 57. The discharge part 5 is bent so that the hose 57 extends to one side in the left-right direction, turns back midway, and extends to the other side. In other words, the hose 57 is bent in a "U" shape, and the nozzle 51 is accommodated in the discharge part accommodating part 102 of the main body 1 with the nozzle 51 parallel to the rotation axis direction of the main body 1. In other words, the nozzle 51 has a cylindrical shape as a whole, and is accommodated with its cylindrical axis parallel to the rotation axis direction. In this state (accommodated state), the discharge port 511 of the nozzle 51 faces the right wall 13 that constitutes the discharge part accommodating part 102. Note that, because the nozzle 51 is inserted into the discharge part accommodating part 102 from the left side, the right wall 13 facing the discharge port 511 can also be said to be the bottom of the discharge part accommodating part 102.

[0022] (1) Hose The hose 57 is configured to be bendable and stretchable. The opening shape and opening area of ​​the inlet of the hose 57 are the same as those of the outlet, and the opening shape is circular. The inlet of the hose 57 faces the outlet opening 233 of the hot air supply unit 20, and the rotation axis of the blower means 21 intersects with the opening plane of the inlet. Here, an imaginary line of the rotation axis passes through the center of the inlet of the hose 57 or its vicinity. This allows the hot air generated by the hot air supply unit 20 to flow smoothly into the hose 57. The inlet (opening area) of the hose 57 is larger than the suction port 213a (opening area) of the hot air supply unit 20 of the blowing means 21. This allows the hot air to be blown out over a wide range.

[0023] (2) Nozzle As shown in Figure 2, the nozzle 51 has a nozzle main body 52 having one end on one side in the first direction into which warm air flows from the main body 1 and an outlet 511 at the other end on the other side in the first direction, and a support member 53 supported by a first support portion 521 of the nozzle main body 52. Here, the nozzle 51 has a support member 54 that is supported by a second support portion 523 of the nozzle body 52. ​​In order to distinguish the support members, the support member 53 will be referred to as a first support member 53, and the support member 54 will be referred to as a second support member 54 for convenience.

[0024] (2-1) Nozzle body The nozzle main body 52 is cylindrical, and one end of the hose 57 is connected to one side in the first direction. Specifically, as shown in FIG. 14, the other end of the hose 57 is fixed on the other side of the end on one side in the first direction. The extension direction of the cylindrical axis of the nozzle main body 52 (also referred to as the "cylindrical axis direction") coincides with the first direction. This allows the hose 57 to be longer overall, even if the length of the hose exposed from the main body 1 is the same, compared to when the hose 57 is connected to one side of the nozzle main body 52. As shown in the enlarged view of Figure 14, the hose 57 is fixed in the first direction by bringing both end faces of the connecting body 553 in the first direction into contact with or close to the extension portion 551a extending from the inner surface of the nozzle body 52 toward the cylindrical axis and the extension portion 555a of the attachment body 555.

[0025] 9 and 10, the nozzle body 52 has a first support portion 521 that rotatably supports the first support member 53, a first restricting portion 522 that restricts the rotation of the first support member 53, a second support portion 523 that rotatably supports the second support member 54, a second restricting portion 524 that restricts the rotation of the second support member 54, a first recess 525 that corresponds to the movable range of the first support member 53, a second recess 526 that fits the second support member 54, and a locking portion 528 that locks with the locked portion 12b of the main body 1 when the nozzle 51 is housed in the discharge portion housing portion 102 of the main body 1. Note that the first recess 525 and the second recess 526 are not essential components. Furthermore, the steps 525a, 525b, 526a, and 526b may be convex portions based on the flat portions 525c and 526c.

[0026] The rotation axis of the first support member 53 extends in the width direction perpendicular to the first direction (cylinder axis direction) and the up-down direction, based on the state in which the first support member 53 is positioned on the upper side of the nozzle body 52. ​​A state in which the first support member 53 is close to the nozzle body 52 is called a closed state (or first state), and a state in which the first support member 53 is separated from the nozzle body 52 is called an open state (or second state), and the direction of rotation from the closed state to the open state is called an opening orientation, and the direction of rotation from the open state to the closed state is called a closing orientation. In other words, when the discharge part 5 is inserted between a mattress and a comforter, which are an example of an object to be dried, the direction away from the mattress is called an opening orientation, and the direction towards the mattress is called a closing orientation. The first support portion 521 is provided on the other end side in the first direction. The first support portion 521 is configured as a fitting hole or a fitting hole into which the first supported portion (convex portion) 533 of the first support member 53 fits. The first support portion 521 is provided on flat portions 525c of first recesses 525 that face each other in the width direction and are part of the peripheral wall 527 that constitutes the nozzle body 52.

[0027] As shown in Figure 9, the first recess 525 is composed of a flat portion 525c formed in the rotation area of ​​the extension portion 532 of the first support member 53, a closing step 525a formed on the closing edge of the rotation area, and an opening step 525b formed on the opening edge of the rotation area. In other words, the first recess 525 is formed so that at least the area between the position where the closed side edge 532b on the closed side of the extension portion 532 of the first support member 53 in the closed state is located and the position where the open side edge 532a on the open side of the extension portion 532 of the first support member 53 in the open state is located is recessed.

[0028] The first restricting portion 522 is provided to protrude on the rotation trajectory of the first support member 53 (extension portion 532), protrudes outward in the width direction, and is retractable in the width direction. In this embodiment, the first restricting portion 522 is provided on a flat portion 525c of the first recess 525. As shown in FIG. 11(a), the first restricting portion 522 is formed, for example, inside a "U"-shaped through groove 522a. The first restricting portion 522 has a base end portion 522b and an abutting portion 522c on the opposite side of the base end of the base end portion 522b, and is configured to be elastically deformable inward in the width direction. The abutting portion 522c protrudes outward in the width direction more than the base end portion 522b. As a result, the abutment portion 522c abuts against the open end edge 532a of the extension portion 532 of the first support member 53 in the closed state as shown in Figure 12(a), and against the closed end edge 532b of the extension portion 532 of the first support member 53 in the open state as shown in Figure 12(b), thereby restricting the rotation of the first support member 53.

[0029] The rotation axis of the second support member 54 extends in the vertical direction based on the state in which the first support member 53 is located on the upper side of the nozzle body 52. ​​A state in which the second support member 54 is close to the nozzle body 52 is referred to as a closed state (or first state), and a state in which the second support member 54 is separated from the nozzle body 52 is referred to as an open state (or open state), and the direction of rotation from the closed state to the open state is referred to as an open orientation, and the direction of rotation from the open state to the closed state is referred to as a closed orientation. Note that when the discharge part 5 is inserted between a mattress and a comforter, which are an example of an object to be dried, the second support member 54 rotates along the mattress, and therefore the open orientation and the closed orientation are horizontal to the mattress. The second support portion 523 is provided on the other end side in the first direction. The second support portion 523 is configured as a fitting hole or a fitting hole into which the second supported portion (convex portion) 543 of the second support member 54 fits. The second support portion 523 is provided on the flat portion 526c of the second recess 526, which is on the peripheral wall 527 that configures the nozzle body 52.

[0030] As shown in Figure 10, the second recess 526 is composed of a flat portion 526c formed in the rotation area of ​​the extension portion 542 of the second support member 54, a closing side step 526a formed on the closing side edge of the rotation area, and an opening side step 526b formed on the opening side edge of the rotation area. In other words, the second recess 526 is formed so that at least the area between the position of the closed side edge 542b on the closed side of the extension portion 542 of the second support member 54 in the closed state and the position of the open side edge 542a on the open side of the extension portion 542 of the second support member 54 in the open state is recessed. The second recess 526 is formed in an area that matches the shape of the second support member 54 in the closed state, and an area that matches the shape of the extension 542 of the second support member 54 in the open state.

[0031] The second restricting portion 524 is provided to protrude on the rotation trajectory of the second support member 54 (extension portion 542), juts out downward, and is movable up and down. In this embodiment, the second restricting portion 524 is provided on the lower surface portion (flat portion 526c) of the second recess 526 that is perpendicular to the rotation axis. As shown in FIG. 11(b), the second restricting portion 524 is formed, for example, inside a "U"-shaped through groove 524a. The second restricting portion 524 has a base end portion 524b and an abutting portion 524c on the opposite side of the base end of the base end portion 524b, and is configured to be elastically deformable upward. The abutting portion 524c protrudes downward more than the base end portion 524b. As a result, the abutment portion 524c abuts (comes close to) the closing edge 542a of the extension portion 542 of the second support member 54 in the closed state as shown in Figure 13(a), and abuts (comes close to) the opening edge 542b of the extension portion 542 of the second support member 54 in the open state as shown in Figure 13(b), thereby restricting the rotation of the second support member 54.

[0032] The locking portion 528 is provided at a position closer to one end of the nozzle body 52 in the first direction than the other end. The locking portion 528 is provided on the first support member 53 side of the peripheral wall 527 of the nozzle body 52, and is arranged to avoid the rotational path of the first support member 53. In other words, as shown in Fig. 14, the locking portion 528 is provided at a position that allows (without interfering with) the rotation of the first support member 53. The locking portion 528 is provided with an engagement hole (groove) 528a (see FIG. 9) for hooking a cable tie (not shown) for maintaining the bundled state of the power cord 35 after folding it multiple times or rolling it up. This eliminates the need to provide a portion for supporting the bundled power cord 35 on the main body 1 or the like.

[0033] 9 and 10, nozzle main body 52 includes a cylindrical body 551, a connector 553 that is provided on the inlet side of cylindrical body 551 and that is for connecting to hose 57, an attachment 555 that attaches connector 553 to cylindrical body 551, and a discharge port body 557 that has an opening that forms discharge port 511. Note that connector 553 is attached to cylindrical body 551 after being connected to hose 57, and therefore may be a part of hose 57.

[0034] (2-2) First support member When the nozzle 51 is placed below the objects to be dried, the first support member 53 is in an open state as shown in FIG. 2 to support the objects to be dried and form a flow path through which hot air flows between the objects to be dried. The first support member 53 has a long plate shape and is shaped so that in the closed state it fits along the peripheral wall of the nozzle main body 52. ​​Specifically, the nozzle main body 52 has a cylindrical shape, a polygonal tube shape, a polygonal tube shape with rounded corners, or a shape similar to these, and the cross section of the first support member 53 has an arc shape or a shape similar to an arc. In the first support member 53, the ends closer to the first support portion 521 are referred to as the proximal side and the proximal end, and the ends farther from the first support portion 521 are referred to as the distal side and the distal end. As described above, the first support member 53 is rotatably supported by the first support portion 521, and in a state where the first support member 53 is supported so as to extend in a second direction intersecting the first direction as shown in FIG. 14 (the state shown in FIG. 2, which is also the open state), the distal end 53a is located on the other side of the first direction than the first support portion 521. The second direction here is a direction that intersects the rotation direction with respect to the first direction at an angle of 90° or more. The angle between the first direction and the second direction may be determined, for example, by using an imaginary line ("L1" in FIG. 10) that passes through the center of the first support member 53 in the width direction and extends in the longitudinal direction.

[0035] As shown in Figures 9 and 10, the first support member 53 has a rectangular shape when viewed from above and a main body portion 531 whose cross-sectional shape is arc-shaped or arc-like, an extension portion 532 extending from the other end of the main body portion 531 in the first direction (longitudinal direction) to the other side in the first direction, and a first supported portion 533 rotatably supported by the first support portion 521 of the nozzle main body 52. The main body 531 has an operating portion (notched portion) 531a that can be used when rotating the first support member 53, and a notched portion 531b that prevents interference with the locking portion 528 of the nozzle main body 52 when rotating. The main body 531 is provided with an engagement hole 531a for hooking a cable tie (not shown) for maintaining the bundled state of the power cord 35 after folding it multiple times or rolling it up. This eliminates the need to provide a portion for supporting the bundled power cord 35 on the main body 1, etc.

[0036] The extension portions 532 extend along an imaginary line that passes through the rotation center and extends parallel to the longitudinal direction of the main body portion 531. In other words, there are a pair of extension portions 532, and they are provided on both ends of the main body portion 531 in the width direction. The first supported portion 533 is provided on the extension portion 532 on the opposite side to the main body portion 531. As shown in FIG. 11(c), the first supported portion 533 is configured as a convex portion that protrudes inward in the width direction. The convex portion has a small diameter region 533a and a large diameter region 533b, and the large diameter region 533b is configured to be elastically deformable in the radial direction. The first supported portion 533 is made elastically deformable by a groove portion 533c that is formed in the convex portion and extends in a direction perpendicular to the direction of elastic deformation. When the first supported portion 533 is attached to the first supporting portion (through hole) 521, the large diameter region 533b elastically deforms and passes through the first supporting portion (through hole) 521 from the outside in the width direction, and the small diameter region 533a fits into the first supporting portion (through hole) 521. The cross-sectional shape of the small diameter region 533a and the opening shape of the first supporting portion (through hole) 521 are circular.

[0037] 14, when the first support member 53 is supported by the first support part 521 so as to extend in the first direction, the distal end 53a of the first support member 53 is formed to extend further to one side in the first direction than the nozzle body 52. ​​This allows the first support member 53 to be longer, and the gap between the material to be dried and the nozzle 51 can be increased during use. 1(a), the length of the first support member 53 is configured so that one end (distal end 53a) of the first support member 53 in the first direction does not protrude from the discharge portion accommodating portion 102 (housing 10) when the nozzle 51 is accommodated in the discharge portion accommodating portion 102. This allows the first support member 53 to be long while being accommodated compactly, thereby improving the design. In particular, the first support member 53 is supported on the other side in the first direction, i.e., on the discharge port 511 side, and is inserted into the discharge portion accommodating portion 102 from the discharge port 511 during storage, so the tip of the nozzle 51 can be inserted to the deepest (rear) part of the discharge portion accommodating portion 102. This allows the first support member 53 to be stored compactly while being long.

[0038] (2-3) Second support member When the nozzle 51 is placed below the material to be dried, the second support member 54 can stably support the nozzle 51 by being in an open state as shown in FIG. In the closed state, the second support member 54 has a shape that fits along the peripheral wall of the nozzle body 52. ​​Specifically, the nozzle body 52 has a cylindrical shape, a polygonal cylindrical shape, a polygonal cylindrical shape with rounded corners, or a similar shape, and in the closed state, the cross section of the second support member 54 that is perpendicular to the cylindrical axis of the nozzle body 52 has an arc shape or a similar shape. As described above, the second support member 54 is rotatably supported by the second support portion 523. When the second support member 54 is in the open state, it extends in a third direction that is different from the first and second directions. The third direction here is a direction that intersects with the first direction when viewed from above, and is a direction that intersects with the rotation direction at an angle of 70 to 110° with respect to the first direction. The angle between the first and third directions may be determined, for example, by using an imaginary line ("L2" in FIG. 10) that passes through the rotation axis of the second support member 54 in the closed state and extends in the first direction (the longitudinal direction of the nozzle body 52). The second support members 54 are located on both sides of the cylindrical axis in the width direction when the nozzle 51 is viewed from above. The two support members 54 are also provided symmetrically with respect to the cylindrical axis. This makes it possible to prevent the nozzle body 52 from rotating around the cylindrical axis.

[0039] As shown in Figures 9 and 10, the second support member 54 has a main body portion 541 having an arc-shaped or arc-like shape corresponding to 1 / 4 of the angle of the peripheral wall of the nozzle main body 52, an extension portion 542 extending from the other end of the main body portion 541 in the first direction (the longitudinal direction of the nozzle main body 52) to the other side in the first direction, and a second supported portion 543 rotatably supported by the second support portion 523 of the nozzle main body 52. The main body 541 has an operating portion (notched portion) 541a that can be used when rotating the second support member . The extension portion 542 extends along an imaginary line that passes through the rotation center and is parallel to the first direction. The second supported portion 543 is provided on the extension portion 542 on the opposite side from the main body portion 541. The second supported portion 543 is configured as a convex portion that protrudes inward in the vertical direction. The convex portion has a small diameter region 543a and a large diameter region 543b, and the large diameter region 543b is configured to be elastically deformable in the radial direction. The second supported portion 543 is made elastically deformable by a groove portion 543c formed in the convex portion and extending in a direction perpendicular to the direction of elastic deformation. When the second supported portion 543 is attached to the second supporting portion (through hole) 523, the large diameter region 543b elastically deforms and passes through the second supporting portion (through hole) 523 from below, and the small diameter region 543a fits into the second supporting portion (through hole) 523. The cross-sectional shape of the small diameter region 543a and the opening shape of the second supporting portion (through hole) 523 are circular.

[0040] (3) Rotation of the first support member (3-1) From closed state to open state In the closed state shown in Figure 12(a), the extension portion 532 of the first support member 53 is located between the first restricting portion 522 and a step (referred to as the closed side step) 525a located on the closing side of the first recess 525, and is in a position close to the first restricting portion 522 and the closed side step 525a, thereby restricting the rotation of the first support member 53. When the first support member 53 is rotated in the opening direction, the contact portion 522c of the first restricting portion 522 is recessed in the width direction, and the first support member 53 is rotated in the opening direction. When the first support member 53 is further rotated in the opening direction, the extension portion 532 passes through the abutment portion 522c, and the opening side edge 532a of the extension portion 532 moves toward the opening side step 525b located on the opening side of the first recess 525, the recessed abutment portion 522c returns to its original position. In the open state shown in Figure 12(b), the extension portion 532 after passing through is located between the first regulating portion 522 and the opening side step 525b on the opening side of the first recess 525, and is in a position close to the first regulating portion 522 and the opening side step 525b, thereby restricting the rotation of the first support member 53. In this way, when switching from the closed state to the open state, simply by operating the abutting portion 522c of the first restricting portion 522 and rotating the first support member 53, the restriction of rotation in the open state can be easily performed.

[0041] (3-2) From open to closed state In the open state shown in Figure 12 (b), the extension portion 532 of the first support member 53 is located between the first restriction portion 522 and the opening side step 525b of the first recess 525, restricting the rotation of the first support member 53. When the first support member 53 is rotated in the closing direction, the abutting portion 522c of the first restricting portion 522 is recessed in the width direction, and the first support member 53 is rotated in the closing direction. When the first support member 53 is further rotated in the closing direction, the extension portion 532 passes through the abutment portion 522c, and the closed side edge 532b of the extension portion 532 rotates toward the closed side step 525a of the first recess 525, the recessed abutment portion 522c returns to its original position. In the open state shown in FIG. 12(a), the extending portion 532 after passing through restricts the rotation of the first support member 53 at a position between the first restricting portion 522 and the closing-side step 525a of the first recess 525. In this way, when switching from the open state to the closed state, simply by operating the abutting portion 522c of the first restricting portion 522 and rotating the first support member 53, the restriction of rotation to the closed state can be easily performed.

[0042] (3-3) Nozzle body locking part The locking portion 528 of the nozzle body 52 is provided so as not to interfere with the first support member 53 which rotates. 4, first support member 53 has a notched portion 531b at the end of nozzle body 52 on the side closer to first support portion 521. Note that, of the "U"-shaped edge of first support member 53 facing notched portion 531b, the edge on the distal end 53a side is defined as proximal end 53b, and proximal end 53b is located on imaginary line L1 (see FIG. 9). During rotation, the rotation locus R1 of the proximal end 53b of the main body portion 531 of the first support member 53 forms an arc as shown in FIG. Locking portion 528 is disposed so as to avoid rotation locus R1. In other words, locking portion 528 is located inside first support portion 521 with respect to rotation locus R1. Conversely, focusing on notched portion 531b, notched portion 531b is provided so that rotation locus R1 of proximal end 53b is located outside locking portion 528. More specifically, the maximum distance between the rotation axis of first support member 53 and locking portion 528 is configured to be smaller than the distance between proximal end 53b of first support member 53 and the rotation axis. This prevents interference with the locking portion 528 of the nozzle 51 when the first support member 53 rotates.

[0043] (4) Rotation of the second support member (4-1) From closed state to open state In the closed state shown in Figure 13(a), the extension portion 542 of the second support member 54 is located between the second regulating portion 524 and a step (referred to as the closed side step) 526a located on the closing side of the second recess 526, and is in a position close to the second regulating portion 524 and the closed side step 526a, thereby restricting the rotation of the second support member 54. When the second support member 54 is rotated in the opening direction, the contact portion 524c of the second restricting portion 524 is recessed upward, and the second support member 54 is rotated in the opening direction. When the second support member 54 is further rotated in the opening direction, the extension portion 542 passes through the abutment portion 524c, and the opening edge 542a of the extension portion 542 moves toward the opening step 526b located on the opening side of the second recess 526, and the recessed abutment portion 524c returns to its original position. In the open state shown in Figure 13(b), the extension portion 542 after this passage is located between the second restricting portion 524 and the opening side step 526b on the opening side of the second recess 526, and the rotation of the second support member 54 is restricted. In this way, when switching from the closed state to the open state, simply by operating the abutting portion 524c of the second restricting portion 524 and rotating the second support member 54, it is possible to easily restrict rotation in the open state.

[0044] (4-2) From open to closed state In the open state shown in Figure 13(b), the extension portion 542 of the second support member 54 is located between the second restricting portion 524 and the opening side step 526b of the second recess 526, and is in a position close to the second restricting portion 524 and the opening side step 526b, thereby restricting the rotation of the second support member 54. When the second support member 54 is rotated in the closing direction, the contact portion 524c of the second restricting portion 524 is recessed upward, and the second support member 54 is rotated in the closing direction. When the second support member 54 is further rotated in the closing direction, the extension portion 542 passes through the abutment portion 542c, and the closing side edge 542b of the extension portion 542 moves toward the closing side step 526a of the second recess 526, the recessed abutment portion 542c returns to its original position. In the open state shown in Figure 13(a), the extension portion 542 after this passage is located between the second regulating portion 524 and the closing side step 526a of the second recess 526, and is located between the second regulating portion 524 and the closing side step 526a, thereby restricting the rotation of the second support member 54. In this way, when switching from the open state to the closed state, simply by operating the abutting portion 524c of the second restricting portion 524 and rotating the second support member 54, the restriction of rotation to the closed state can be easily performed.

[0045] <Modification> Although the embodiment has been described, the present invention is not limited to this embodiment, and may be modified as follows, for example. Furthermore, the embodiment and the modified examples, or the modified examples may be combined. Furthermore, examples not described in the embodiments and modifications, and design changes within the scope of the present invention are also included in the present invention.

[0046] 1. Main body (1) The housing 10 of the main body 1 has a vertically low box shape, but it may also have a vertically high box shape (a box shape with a small dimension in the front-to-back direction) that has the discharge section accommodating section 102 above the hot air supply unit 20, or it may have a vertically high box shape (a box shape with a small dimension in the front-to-back direction) that has the hot air supply unit 20 extending vertically and the discharge section accommodating section 102 side by side in the horizontal direction (for example, left and right). That is, the hot air supply unit 20 (blowing means 21) and the nozzle 51 may be arranged in a front-to-back manner as in the embodiment, or may be arranged vertically or horizontally. The opening for removing the discharge part 5 is preferably located on one side in the direction in which the hot air supply unit 20 and the discharge part accommodating part 102 are aligned and on one side in the direction perpendicular to the aligned direction.

[0047] (2) The operation unit 40 is provided on the front wall 11, but may be provided on the top wall 14. However, in consideration of wiring etc., it is preferable to provide it on a wall facing (adjacent to) the unit housing section 101. The operation unit 40 has an operation control section, but the operation control section may be provided in the circuit unit 30 . (3) The hot air supply unit 20 is provided with the air blowing means 21 on the upstream side and the heating means 22 on the downstream side, but the arrangement may be reversed. However, in consideration of the heat resistance of the air blowing means 21, it is preferable that the air blowing means 21 is on the upstream side. In the hot air supply unit 20, the inlet opening 232 of the casing 23 and the air intake 13a of the housing 10 are disposed close to each other in the left-right direction, but they may also be disposed apart. However, when air outside the housing 10 is directly drawn into the hot air supply unit 20, it is preferable that the distance between the inlet opening 232 and the air intake 13a be equal to or less than the maximum dimension of the intake 213a. (4) The hot air supply unit 20 has the inlet opening 232 of the casing 23, the suction port 213a of the blower 21, the heating means 22, and the outlet opening 233 on the rotation axis (straight line) of the blower 21, but these may also be arranged in this order on a gently curved line. This allows for smooth air intake and discharge. (5) The hot air supply unit 20 includes the connector 25 for connecting to the hose 57, but the connector 25 may be rotatably fixed directly to the housing 10. Considering assembly efficiency, a structure in which the hot air supply unit 20 and the discharge part 5 are connected to the hose 57 and are incorporated into the housing 10 is preferable. (6) The electronic components 31 and the like of the circuit unit 30 may be mounted on the board 43 of the operation unit 40 to form a single circuit section (single board). Although the board 32 of the circuit unit 30 has been disposed adjacent to the bottom wall 15 and parallel to the bottom wall 15, it may be disposed adjacent to the partition wall 17 and parallel to the partition wall 17, or adjacent to the top wall 114 and parallel to the top wall 14. However, in consideration of assembly efficiency, it is preferable to provide the board 32 on the housing main body side. (7) The discharge portion accommodating portion 102 accommodates the discharge portion 5 or most of the discharge portion 5, but may accommodate all or most of the nozzle 51, for example, with the hose 57 positioned outside the housing 10. In other words, it is sufficient for the discharge portion accommodating portion 102 to accommodate at least the discharge port 511 side of the nozzle 51. (8) The rear wall 12 of the housing 10 is open from a position to the right of the center to the left end position in the left-right direction, but as long as the nozzle 51 can be accommodated from the left side, it may or may not be open from a position to the left of the center to the left end position in the left-right direction.

[0048] 2.Discharge part (1) The nozzle 51 has the first support portion 521 on the other side of the center in the first direction of the nozzle body 52, but the first support portion 521 may be at the center in the first direction or on one side of the center in the first direction. Note that if it is desired to increase the longitudinal length of the first support member 53 (the length in the first direction in the closed state), it is better for the first support portion 521 to be on the other side in the first direction. (2) In the embodiment, the angle A (see Figure 14) between the first direction and the second direction, which is the rotation range of the first support member 53, was 115°. However, if the angle is 90° or more, the load of the weight of the material to be dried acts in the direction of opening the first support member 53, and the first support member 53 can be prevented from closing. Note that the angle A here is based on an imaginary line ("L1" in Figure 9) that passes through the center in the width direction and extends in the longitudinal direction on the surface of the first support member 53 (the surface opposite the nozzle body 52), but it may also be based on another position. The angle A between the first direction and the second direction is 130° or less, preferably 120° or less. By setting the angle A in this range, the load (torque) of the material to be dried acting on the first supporting part 521 and the first supported part 533 can be reduced. The angle A between the first direction and the second direction may be less than 90°, in which case this can be achieved by providing a regulating part (a first auxiliary support part that supports from the closing side in the rotation direction) that regulates rotation in the closing direction.

The second support member 54 has a rotation axis on the other side in the first direction and rotates so as to open and close on one side in the first direction, but may be configured so as to open and close on the other side in the first direction. (6) In the stored state, the first support member 53 extends further than the nozzle body 52 on one side in the first direction in the closed state (a state in which the first support member 53 is supported by the first support portion 521 so as to extend in the first direction), but may be positioned at the same position as one end of the nozzle body 52 or may be positioned on the other side of the one end of the nozzle body 52. (7) In the housed state, the nozzle 51 is arranged so as to overlap with the blower means 21 in the front-to-rear direction, but the end of the nozzle 51 on the discharge port 511 side may be located on the side of the outlet opening 233 in the rotational axis direction with respect to the inlet opening 232 of the casing 23, or on the opposite side of the outlet opening 233 in the rotational axis direction, or may be in the same position. In consideration of effective use of the housing space, it is preferable that the end of the nozzle 51 on the discharge port 511 side is located near the inlet opening 232 of the casing 23.
