[0008] <Embodiment>

[0009] 1. Overview The schematic structure of the drying apparatus X according to this embodiment will be explained with reference to Figures 1 and 2. The drying apparatus X comprises a main body 1 that generates hot air and a discharge unit 5 that discharges the hot air generated in the main body 1 from a discharge port 511. The main unit 1 includes a hot air supply unit 20 for supplying hot air, a circuit unit 30, and an operation unit 40, all housed in a casing 10. The discharge unit 5 comprises a nozzle 51 and a hose 57 that can be bent and extended, and is connected to the main body 1 via the hose 57. The discharge unit 5 is attached to the main body 1 by bending the hose 57 into a "U" shape, as shown in Figure 1(a). When in use, the nozzle 51 is removed from the main body 1, as shown in Figure 1(b). Note that the state in which the nozzle 51 is attached to the main body 1 is referred to as the attached state, and the state in which the nozzle 51 is detached from the main body 1 is referred to as the detached state. The drying device X dries items to be dried, such as bedding like futons, shoes, and laundry. For example, when drying a mattress and a comforter, the nozzle 51 is inserted between the mattress and the comforter. In this case, by spreading the support member 53 of the nozzle 51 (see Figure 1(b)), the hot air discharged from the nozzle 51 can be supplied to a wide area.

[0010] Here, in the nozzle 51, the direction connecting the part where the hose 57 is connected and the discharge port 511 is defined as the first direction, the direction in which the nozzle 51 and the main body 1 (housing 10) face each other (are adjacent) in the mounting state shown in Figure 1(a) is defined as the third direction, and the direction perpendicular to the first and third directions is defined as the second direction. In the main body 1, the surface and side to which the nozzle 51 is attached are designated as the rear (or rear surface) and rear side, and the surface and side facing the rear in a third direction are designated as the front and front side. When viewed from the front, the surface and side located on the right side are designated as the right surface and right side, the surface and side facing the right surface in a second direction are designated as the left surface and left side, the surface and side to which the hose 57 is located in the attached state are designated as the top surface and upper side, and the surface and side facing the top surface in a first direction are designated as the bottom surface and lower side. In the nozzle 51, the surface and side attached to the main body 1 are designated as the bottom surface (or lower surface) and bottom side (or lower side), the surface and side facing the bottom surface in the third direction are designated as the top surface and upper side, the surface and side on which the discharge port 511 is located are designated as the front surface and front side, the surface and side on which the hose 57 is located are designated as the rear surface and rear side, the surface and side located to the right when viewed from the opposite side of the discharge port 511 are designated as the right surface and right side, and the surface and side facing the right surface in the second direction are designated as the left surface and left side. The following will describe each part.

[0011] 2. Main body As shown in FIGS. 1 and 2, the main body 1 is detachably attached to the back side, that is, outside the housing 10, the nozzle 51. In other words, the entire nozzle 51 is attached in an exposed state. Thereby, the main body 1 does not need to have a space inside the housing 10 for accommodating a part of the discharge unit 5 (for example, the nozzle 51), and the housing (device) can be miniaturized. Further, since the longitudinal direction of the hot air supply unit 20 described later is parallel or substantially parallel to the first direction, the dimensions in the second direction and the third direction can be reduced, and it can be made slim.

[0012] (1) Housing This will be mainly described with reference to FIGS. 2 to 5. Inside the housing 10, the hot air supply unit 20, the circuit unit 30, and the substrate 43 are accommodated in a state where the operating means 41 and the display means 42 of the operation unit 40 are exposed to the outside of the housing 10. The housing 10 is box-shaped. Here, it is box-shaped and elongated in the first direction. The cross-sectional shape perpendicular to the first direction is square or nearly square. The housing 10 is composed of a plurality of members. Here, it is composed of two members, a housing main body 101 having an opening on the front side and a lid body 102 closing the opening. The lid body 102 is mainly composed of the front wall 11, and the housing main body 101 is mainly composed of the rear wall 12, the right wall 13, the left wall 14, the upper wall 15, and the lower wall 16. The rear wall 12 constitutes the back surface portion of the main body 1.

[0013] As shown in FIG. 4, the lid body 102 has through holes 11a for the operating means 41 and the display means 42 of the operation unit 40 in the front wall 11. The lid body 102 has protrusions 11b for positioning the operation unit 40, boss screws 11c for supporting and fixing the operation unit 40, engaging portions 11d engaging with the substrate of the operation unit 40, boss screws 11e for fixing to the housing main body 101, ribs 11f for restricting the position of the hot air supply unit 20 from the front side, etc. on the inner surface of the front wall 11. As shown in Figure 5, the housing body 101 has a boss 12a for screws that secure the lid 102, a rib-shaped support portion 12b that supports the hot air supply unit 20 from the rear, and a fixing portion 12c that secures the holder 36 that holds the power cord 35 on the inner surface of the rear wall 12. There are four bosses 12a, one on each side (top, bottom, left, and right). The lower bosses 12a are formed on the lower wall 16 and are connected to the retaining portion 16b that holds the filter 104 and the lower wall 16. The upper boss 12a, specifically the left boss 12a (see Figure 5(a)), is formed on the left wall 14 and is connected to the retaining portion 14b that holds the substrate 32. This allows for reinforcement of the bosses 12a and the retaining portion 14b. As shown in Figure 5, the support portion 12b is provided such that both its left and right ends extend downward and connect to the lower wall 16 (and its holding portion 16b). The fixing portion 12c has a screw hole in the U-shaped portion formed in the rear wall 12 into which a screw for fixing the holder 36 is screwed.

[0014] As shown in Figure 3, the housing body 101 has, for example, a through hole 13a for the power cord 35 and an air intake port 13b on the right wall 13, and as shown in Figure 5(b), it has, for example, a pair of retaining parts 13c having grooves for holding the upper and lower ends of the filter 103 that covers the air intake port 13b so that it can slide from the front, and a retaining part 13d having a groove into which the rear end of the filter 103 is inserted from the insertion direction (front), on the inner surface of the right wall 13. As shown in Figure 4, the housing body 101 has an air intake port 14a on the left wall 14, and as shown in Figures 3 and 5(a), it has holding parts 14b and 14c on the inner surface of the left wall 14 for holding the circuit board 32 of the circuit unit 30. The holding parts 14b and 14c have grooves into which the upper and lower ends of the circuit board 32 are inserted so as to be slidable from the front.

[0015] As shown in Figures 3 and 5, the housing body 101 has, for example, an air intake port 16a on the lower wall 16, and a pair of retaining parts 16b having grooves for holding both the left and right ends of a filter 104 that covers the air intake port 16a so that it can slide from the front, and a retaining part 16c having a groove into which the rear end of the filter 104 is inserted from the insertion direction (front), on the inner surface of the lower wall 16. As shown in Figure 3, the housing body 101 has a pair of legs 16d that protrude downward from both the left and right sides relative to the air intake port 16a of the lower wall 16. The legs 16d are composed of protruding portions that extend in the front-rear direction. This prevents the air intake port 16a from being blocked by the installation surface when the main body 1 is erected against the installation surface (with the lower wall 16 facing the installation surface). The housing body 101 has an opening 15a for the hose 57 and an air intake port 15b on the upper wall 15, and a support portion 15c on the inner surface of the upper wall 15 that supports the protruding portion 264 (see Figures 3 and 4) of the hot air supply unit 20 connected to the hose 57. The support portion 15c is formed as a rib extending downward from the upper wall 15 and has a groove into which the protruding portion 264 is inserted and removed from the front. There is a pair of support portions 15c on both the left and right sides.

[0016] This will be explained using Figure 4 and the enlarged view within Figure 4. The housing body 101 has a mounting portion for attaching the nozzle 51. The mounting section is located on the back side of the main body 1. Here, as the nozzle 51 moves (slides) from above relative to the main body 1, the engaging portion 542 of the nozzle 51 (see Figure 9) engages with the engaged portion 105. The engaged portion 105 is provided on the upper side of the rear wall 12. The engaged portion 105 has a first groove 151 that extends in a first direction, that is, in the sliding direction, and the engaged portion 542 is inserted into this first groove 151. The engaged portion 105 has a first groove 151, and a second groove 153 extending from the lower end of the first groove 151 in a direction perpendicular to the insertion direction, on the inner side in the insertion direction (first direction) of the engaging portion 542. Specifically, the housing body 101 has recesses 155 at the upper end, specifically at the corners of both the left and right ends, and protruding portions 157 that extend outward in the left-right direction from the rear end of the recess 155 and create a gap with the lower surface (the inner surface in the sliding direction) 155a of the recess 155. The first groove 151 is formed between the front surface 155b of the recess 155 and the protruding portion 157, and the second groove 153 is formed between the lower surface 155a of the recess 155 and the protruding portion 157.

[0017] The housing body 101 has a support portion 106 that supports the mounted nozzle 51 from below. The support portion 106 is composed of a protrusion 161 that projects rearward from the rear wall 12, and the supported portion 544 (see Figure 9) of the mounted nozzle 51 abuts against or is close to the upper surface 161a of the protrusion 161. The protrusion 161 extends in a direction perpendicular to the sliding direction of the nozzle 51 when mounted (this is the second direction). As a result, as shown in Figure 2, the 544 of the mounted nozzle 51 is supported from below by the protrusion 161. The protrusion 161 has two protrusions 162 in the second direction, and a groove 163 is formed between the protrusions 162. The protrusions 162 are, for example, elongated oval frames that are long in the second direction.

[0018] The housing body 101 has a guide portion 107 that guides the guided portion 543 (see Figure 9(a)) of the nozzle 51 as it slides along the back surface of the main body 1 when the nozzle 51 is attached. Here, the guided portion 543 of the nozzle 51 is composed of a protruding portion 543a extending in the sliding direction (see Figure 9(a)), and the housing body 101 has a guide groove portion 171 that extends in the sliding direction and into which the protruding portion 543a fits. The guide groove portion 171 is formed between a first protruding portion 173 and a second protruding portion 175 that project rearward from the rear wall 12 of the housing body 101. The first protruding portion 173 and the second protruding portion 175 are aligned in the second direction. The first protruding portion 173 is formed on the side away from the circuit unit 30 and protrudes in a rectangular, square, or similar frame shape. The second protruding portion 175 is formed on the side closer to the circuit unit 30 and has a second forward protruding portion 175a that protrudes in a rectangular, square, or similar shape, and a second rearward protruding portion 175b that protrudes rearward in a frame-like manner from the periphery of the second forward protruding portion 175a in a third direction. The second forward protruding portion 175a is located in front of the second rearward protruding portion 175b in the third direction, and the second rearward protruding portion 175b is located behind the second forward protruding portion 175a, and the terms "front" and "rear" are used for convenience. Furthermore, the protruding portion 543a fits into and is guided by the guide groove 171 between the first convex portion 173 and the second rear convex portion 175b shown in Figure 4.

[0019] The housing body 101 has a second mounting portion for attaching the nozzle 51. The second mounting section is located on the back side of the main body 1. Here, as the nozzle 51 moves (slides) from above relative to the main body 1, the second engaging portion 545 of the nozzle 51 (see Figure 9) engages with the second engaged portion 108. The second engaged portion 108 is provided on the lower side of the rear wall 12. The second engaged portion 108 has a third groove 181 that extends in the first direction, that is, the sliding direction, and the second engaged portion 545 is inserted into this third groove 181. The third groove 181 is formed on the left-right outer side surfaces of the first protrusion 173 and the second protrusion 175. Since the structure of the left third groove 181 and the right third groove 181 are the same, the left third groove 181 in Figure 4 will be described. The third groove 181 is formed by a protrusion 183 formed on the left side surface 175c of the second protrusion 175. Specifically, the protrusion 183 has a lower protrusion 183a that protrudes so as to straddle the left side surface 175c of the second protrusion 175 and the rear wall 12, and an upper protrusion 183b that protrudes so as to extend upward from the rear end of the lower protrusion 183a so as to create a gap with the rear wall 12, and the third groove 181 is formed between the upper protrusion 183b and the rear wall 12.

[0020] (2) Hot air supply unit This will be explained using Figure 6. The hot air supply unit 20 includes, at a minimum, a blowing means 21 having a fan 211 and a drive unit (motor) 213 for driving the fan 211 inside a case 214, and a heating means 22 for heating the air blown out by the blowing means 21 inside a casing 23. Multiple blades for the fan 211 are provided around the rotational centerline of the drive unit 213. Sound-absorbing material or vibration-damping material may be wrapped between the case 214 and the casing 23. The hot air supply unit 20 here comprises a temperature sensor 24 (see Figure 8) attached to the casing 23, a connector 25 for connecting to the hose 57, and a mounting body 26 for rotatably or fixedly (non-rotatably) attaching the connector 25 to the casing 23. Note that the connector 25 is attached to the casing 23 after being connected to the hose 57, so it may be part of the hose 57.

[0021] (2-1) Casing As shown in Figures 6 and 7, the casing 23 is a long cylindrical shape in the direction in which the rotation axis of the blowing 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 aligned with the rotation axis direction (cut by a virtual plane including the rotation axis). The first member 231A and the second member 231B are fixed (joined) by, for example, screws. 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 (down) in the direction of the rotation axis (first direction), and the outlet opening 233 is located on the other side in the direction of the rotation axis. In Figures 6 and 7, in the configuration of the casing 23, the reference numeral "A" is used for components composed of the first member 231A, and the reference numeral "B" is used for components composed of the second member 231B. For example, in the entry opening 232, the portion composed of the first member 231A is labeled "232A," and the portion composed of the second member 231B is labeled "232B." The casing 23 integrally supports the blowing means 21 and the heating means 22 inside, between the inlet opening 232 and the outlet opening 233. Here, the heating means 22 is positioned closer to the outlet opening 233 than to the inlet opening 232, and the blowing means 21 is positioned closer to the inlet opening 232 than to the outlet opening 233. Preferably, the heating means 22 is positioned closer to the outlet opening 233 than to the inlet opening 232, and the blowing means 21 is positioned closer to the inlet opening 232 than to the outlet opening 233. This makes it easier to incorporate the casing 23 into the housing 10 compared to the conventional technology in which the casing housing the blowing means and the casing housing the heating means are separately incorporated into the housing. For example, in conventional technology, it is necessary to incorporate the casings into the housing so that there are no gaps between the casings to prevent pressure loss, but with the configuration of this embodiment, such a need does not arise when incorporating the casing 23 with respect to the blowing means 21 and the heating means 22. The inlet opening 232 is positioned such that its centerline, which passes through its center and extends in the direction of the rotation axis (corresponding to the rotation axis in Figure 6(a)), intersects with the opening surface of the outlet opening 233. This allows air flowing in from the inlet opening 232 to move smoothly (linearly) towards the outlet opening 233 and out through the outlet opening 233. The inlet opening 232 and outlet opening 233 are circular in shape. The opening area (diameter) of the outlet opening 233 is larger than the opening area (diameter) of the inlet opening 232. This allows the air blown out from the blowing means 21 to come into contact with the surface of the heating means 22 more broadly, thus ensuring sufficient heating. In addition, the portion of the casing 23 that supports the blowing means 21 is cylindrical, and the portion that supports the heating means 22 is rectangular. The casing 23 has an outlet 234 for leading the connection terminals 223 of the heating means 22 to the outside, and a recess 235 for the temperature sensor 24.

[0022] (2-2) means of blowing air This will be explained using Figure 6. The blowing means 21 blows air drawn in from the intake ports 13b and 16a of the main body 1 toward the heating means 22. The blower unit 21 comprises a motor 213, a fan 211 positioned on the outer circumference of the motor 213, and a case 214 housing the motor 213 and fan 211, and is integrated into a single unit. The motor 213 can be a DC motor (including brushed and brushless types) or an AC motor. Here, a brushless motor (BLDC) is used, which allows for high output and energy saving. The motor 213 is positioned so that its rotation axis coincides with or is close to the central axis of the casing 23. The case 214 is cylindrical and has multiple protrusions 214a projecting radially outward from its outer circumference. The blower unit 21 is supported by the casing 23 by the protrusions 214a contacting the inner circumferential surface of the casing 23. This reduces the contact area between the blower unit 21 and the casing 23, suppressing vibrations of the casing 23 and improving quietness. The case 214 may be made of resin molding or of an elastic material. The blower 21 is positioned upstream of the heating 22 in the direction of its rotation axis. In other words, the heating 22, the blower 21, the inlet opening 232 of the casing 23, and the intake port 16a of the housing 10 are arranged in this order from downstream in the direction of the rotation axis. The air blower 21 is positioned so that its axis of rotation intersects with the opening surface of the outlet opening 233. This allows the air blower 21 to draw air in from the intake port 213a and expel the air smoothly (linearly) from the outlet opening 233. The blowing means 21 is positioned such that its suction port 213a faces the inlet opening 232 of the casing 23. As a result, air flowing in from the inlet opening 232 is directed to the suction port 213a of the blowing means 21 in 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 direction of the rotation axis, the outer edge of the motor 213 is contained within the opening area of ​​the outlet opening 233. As a result, negative pressure is easily generated at the inlet opening 232, which improves suction performance.

[0023] (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. The heater 221 has a rectangular or similar shape when viewed from the direction of the rotation axis. The heater 221 can be a ceramic heater (PTC heater) or the like. As shown in Figure 8(a), the temperature sensor 24 for detecting the temperature of the heater 221 is fitted into a recess 235 of the casing 23. The recess 235 is recessed towards the heater 221 in order to bring the heater 221 and the temperature sensor 24 closer together. Alternatively, the temperature sensor 24 may be exposed inside the casing 23 through a through hole instead of the recess 235. In this case, the temperature sensor 24 may be in contact with or separated from the heater 221. Furthermore, various sensors such as bimetallic strips, thermal fuses, and thermistors can be used as the temperature sensor 24. As shown in Figure 8(a), the heating means 22 is biased toward the temperature sensor 24 by the elastic body 27. This makes it easier for the temperature sensor 24 to approach the heater 221, enabling highly accurate temperature detection. The elastic body 27 is formed, for example, by curving a plate. The elastic body 27 has at least a base portion 271 disposed in the casing 23 and an extended portion 273 that bends sharply from the base portion 271 and extends toward the heater 221, with the extended portion 273 being 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 the longitudinal and widthwise ends of the base portion 271 contacting the inner wall constituting the recess 236, and the elastic body 27 is housed with the extended portion 273 in contact with the heater 221. The temperature sensor 24 and the elastic body 27 face each other with the heater 221 in between. The casing 23 also functions as a casing that supports the heater 221 by contacting it.

[0024] (2-4) Connector As shown in Figures 6 and 7, the connector 25 is cylindrical with a bottom, a spiral projection 253 formed on the inner surface of the cylindrical portion 251, and a through hole 257 formed in the bottom portion 255. The end of the hose 57 is inserted into the cylindrical portion 251 and supported by the projection 253. A filter function is formed by the through hole 257 in the bottom portion 255. The hose 57 may be detachable from the connector 25. The cylindrical portion 251 of the connecting body 25 is inserted into the cylindrical portion 237 at the other end (outlet opening 233 side) in the direction of the rotation axis of the casing 23.

[0025] (2-5) Mounting body As shown in Figure 6, the mounting body 26 has a recess 263 with an opening 262 at its bottom 261, and a protruding portion 264 extending outward from the edge of the recess 263 opposite to the bottom 261. The mounting body 26 is fixed to the casing 23 by screws 269, with the recess 263 covering the cylindrical portion 251 of the connecting body 25 that protrudes from the casing 23 in the direction of the rotation axis, and the peripheral portion of the opening 262 at the bottom 261 in contact with the end face of the cylindrical 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 screwed into the fixing portion (threaded hole or screw hole) 238 of the casing 23. The protruding portion 264 of the mounting body 26 is supported by the support portion 15c of the housing body 101.

[0026] (3) Circuit Unit The circuit unit 30 receives power from the commercial power supply via the power cord 35 and generates drive power to operate the hot air supply unit 20, temperature sensor 24, operation unit 40, etc. As shown in Figures 3 to 5, the circuit unit 30 comprises a plurality of electronic components 31a, 31b and a circuit board 32 on which the plurality of electronic components 31a, 31b are mounted, and is housed within the housing 10. As shown in Figure 5(a), the circuit board 32 is held in place by retaining parts 14b, 14c on the left wall 14. The circuit unit 30 is positioned between the hot air supply unit 20 and the left wall 14. As shown in Figure 3, the electronic components 31a and 31b are positioned on both ends of the substrate 32 in the third direction so as not to interfere with the hot air supply unit 20. Large electronic components 31b (such as electrolytic capacitors) are placed on the rear side of the substrate 32, and a portion (rear) of the electronic component 31b protrudes onto the second protrusion 175 of the rear wall 12, as shown in Figure 5. By utilizing the second protrusion 175 in this way, large electronic components 31b can be accommodated without substantially increasing the size of the housing 10. Since the circuit unit 30 is located outside the casing 23 that houses the heating means 22, it is less susceptible to the heat from the heating means 22. Furthermore, since the circuit unit 30 is positioned on the airflow path of the air drawn in from the intake ports 14a and 15b by the blowing means 21, it is configured to be cooled by the air flowing through this airflow path.

[0027] (4) Operating Unit As shown in Figures 2 to 4, the operating unit 40 has operating means 41 and display means 42 on a substrate 43, and the substrate 43 is fixed to the front wall 11 with the operating means 41 and display means 42 fitted into through holes 11a in the front wall 11. The operating unit 40 includes at least an operating control unit for operating the air blowing means 21, in this case the hot air supply unit 20. The operating control unit is made up of electronic components and is mounted on the circuit board 43 or the circuit board 32 of the circuit unit 30. The substrate 43 is provided in a state parallel to the front wall 11 or along the front wall 11.

[0028] 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 the inlet to the hose 57, and the opening at the other end is the outlet from the hose 57. The discharge section 5 has a bottom surface that faces the mattress. The bottom surface of the discharge section 5 is detachable from the back of the main body section 1. In other words, the discharge section 5 is attached to the back of the main body section 1 with a nozzle 51 that is long in the first direction parallel to the first direction of the main body section 1, while the hose 57 extends to one side (rear side) in the first direction, then bends back and extends to the other side. To put it another way, the hose 57 is curved in a "U" shape. In other words, the nozzle 51 is cylindrical as a whole, and the bottom surface of the nozzle 51 is attached to the back of the main body section 1 with the cylindrical axis of the nozzle 51 parallel to the first direction (longitudinal direction) of the main body section 1. In this state (attached state), the bottom surface of the nozzle 51 faces the back of the main body section 1 (rear wall).

[0029] (1) Hose The hose 57 is configured to be flexible and expandable. The opening shape and area of ​​the inlet of hose 57 here are the same as the opening shape and area of ​​the outlet. The opening shape is circular. The inlet of hose 57 faces the outlet opening 233 of the hot air supply unit 20, and the rotation axis of the blowing means 21 intersects with the opening surface of the inlet of hose 57. Here, an imaginary line extending from the rotation axis passes through the center of or near the inlet of hose 57. This allows the hot air generated by the hot air supply unit 20 to flow smoothly into 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 hot air to be blown over a wide area.

[0030] (2) Nozzle This will be explained primarily using Figures 9 to 11. The nozzle 51 has a nozzle body 52 having one end into which warm air from the main body 1 flows in on one side (rear side) in the first direction, and a discharge port 511 at the other end on the other side (front side) in the first direction, and a support member 53 that is rotatably supported at the support portion 521 of the nozzle body 52. Here, the state in which the support member 53 is close to the nozzle body 52 is defined as the closed state (or first state), and the state in which it is separated from the nozzle body 52 is defined as the open state (or second state).

[0031] The nozzle body 52 is cylindrical, and the other end of the hose 57 is connected to one side in the first direction. The direction of extension of the cylindrical axis of the nozzle body 52 (also called the "cylindrical axis direction") coincides with the first direction.

[0032] As shown in Figure 10, the nozzle body 52 includes a support portion 521 that rotatably supports the support member 53, a restricting portion 522 that restricts the rotation of the support member 53, a first recess 523 that fits into the movable range of the support member 53, a second recess 524 into which the support member 53 fits, and a holding portion 525 that holds (maintains) the closed state of the support member 53. Note that the first recess 523 and the second recess 524 are not essential components. The nozzle body 52 has an engaging portion 542 that engages with the engaged portion 105 (see Figure 4) of the main body 1, and a guided portion 543 that is guided by the guide portion 107 (see Figure 4) of the main body 1, on the bottom wall 527 side. The engaging portion 542 is provided using the leg portion 541. The bottom wall 527 constitutes the bottom surface. The nozzle body 52 has a supported portion 544 on the bottom wall 527 side that is supported by the support portion 106 (see Figure 4) of the main body 1. The nozzle body 52 has a second engaging portion 545 on the bottom wall 527 side that engages with the second engaged portion 108 (see Figure 4) of the main body portion 1. The nozzle body 52 has legs 528 on the bottom wall 527 that are spaced apart in the second direction. The guided portion 543, the supported portion 544, the second engaging portion 545, and the legs 528 are provided using two recesses 546 formed on the bottom wall 527 at intervals in the second direction.

[0033] The pivot axis of the support member 53 extends in a second direction (width direction) that is perpendicular to the first direction (cylindrical axis direction) and the third direction (vertical direction), with reference to the state in which the support member 53 is positioned on the upper side of the nozzle body 52 (for example, as shown in Figure 9). Here, the direction of rotation of the support member 53 from the closed state to the open state is defined as the opening direction, and the direction of rotation from the open state to the closed state is defined as the closing direction. To put it another way, if the discharge unit 5 is positioned between a mattress and a comforter, which are examples of items to be dried, the direction away from the mattress is the opening direction, and the direction towards the mattress is the closing direction. The support portion 521 is provided on the other end side (discharge port 511 side) in the first direction. The support portion 521 is composed of a fitting hole or fitting hole into which the supported portion (protruding portion) 533 of the support member 53 is fitted. The support portion 521 is provided on the flat portion 523c of the first recess 523 that is part of the peripheral wall of the nozzle body 52 and faces the second direction.

[0034] As shown in the enlarged view of Figure 10(b), the first recess 523 is composed of a flat portion 523c formed in the rotation region of the extended portion 532 of the support member 53, a closed-side step 523a formed at the closing-side edge of the rotation region, and an open-side step 523b formed at the opening-side edge of the rotation region. In other words, the first recess 523 is formed such that, in Figure 11, at least the area between the position where the closed-side edge 532b is located on the closing side of the extended portion 532 of the support member 53 in the closed state, as shown in Figure 11(a), and the position where the open-side edge 532a is located on the opening side of the extended portion 532 of the support member 53 in the open state, as shown in Figure 11(b). The depth of the first recess 523 corresponds to the thickness of the extended portion 532 of the support member 53. The first recess 523 is also provided with one or more discharge holes 523d ​​for discharging a portion of the warm air flowing in from the hose 57 to the outside through the nozzle 51.

[0035] The second recess 524 is formed in the region of the upper wall 526 from a position near the center in the first direction to one end. The second recess 524 is recessed in accordance with the main body 531 of the support member 53 in the closed state. Both ends of the second recess 524 in the second direction are connected flush with the flat portion 523c of the first recess 523. The depth of the second recess 524 corresponds to the thickness of the main body 531 of the support member 53.

[0036] The restricting portion 522 is provided so as to protrude on the rotational trajectory of the support member 53 (extension portion 532), and is configured to extend outward in the second direction and to be able to extend and retract in the second direction. In this embodiment, the restricting portion 522 is provided in the flat portion 523c of the first recess 523. As shown in the enlarged view of Figure 10, the restricting portion 522 is formed inside, for example, a "U" shaped through groove 522a. The restricting portion 522 has a base end portion 522b and a contact portion 522c formed on the opposite side of the base end of the base end portion 522b, and is configured to be elastically deformable inward in the second direction. The contact portion 522c protrudes outward in the second direction more than the base end portion 522b. As a result, the contact portion 522c contacts the open end edge 532a of the extended portion 532 of the support member 53 in the closed state, as shown in Figure 11(a), and contacts the closed end edge 532b of the extended portion 532 of the support member 53 in the open state, as shown in Figure 11(b), thereby restricting the rotation of the support member 53 and maintaining the closed or open state.

[0037] The retaining portion 525 is provided in the second recess 524. The retaining portion 525 is made up of a through hole, and the engaging portion 534 of the support member 53 engages with the through hole. As shown in Figure 9, the legs 528 are composed of protrusions including the outer side surface 546c in the second direction of the recess 546, and are located on both sides in the second direction. With respect to the bottom surface 546a of the recess 546, the legs 528 protrude to one side (downward) in the third direction and extend along the first direction. This prevents the legs 528 from contacting the mattress and causing the nozzle 51 to rotate (tip over) even when placed on a soft object to be dried, such as a mattress.

[0038] The legs 541 are formed on one end (rear end) of the bottom wall 527 in the first direction. The legs 541 are also formed on both ends (left and right ends) in the second direction, and two are provided spaced apart in the second direction. This allows each leg 541 to be provided with an engaging portion 542. The legs 541 protrude from the bottom wall 527 on one side (downward) in the third direction. This allows the nozzle 51 to be stably installed on the installation surface. As shown in Figure 12, the engaging portion 542 has an extended portion 542a that extends in the sliding direction, spaced apart in the second direction from the inner surface 541a of the leg portion 541 in the second direction, a connecting portion 542b that connects with the leg portion 541 at one end (rear end) of the extended portion 542a in the first direction, and a convex portion (claw portion) 542c that protrudes from the other end (front end) of the extended portion 542a in the first direction to the other side (upward side) in the third direction. The upper surface 542d of the extended portion 542a is an inclined surface that rises upward as it approaches the engagement side in the sliding direction (the other side in the first direction). Furthermore, since the extended portion 542a is connected to the connecting portion 542b on one side (the rear side) in the first direction, the convex portion 542c side of the extended portion 542a becomes elastically deformable in the third direction.

[0039] The guided portion 543 is formed between two recesses 546 that are spaced apart in the second direction, and is composed of a protruding portion 543a that extends in the first direction, with reference to the bottom surface 546a of the recess 546. The dimensions of the recess 546 in the second direction coincide with the dimensions of the first protrusion 173 and the second protrusion 175 of the main body 1 in the second direction. As a result, the nozzle 51 can slide in the first direction when the first protrusion 173 and the second protrusion 175 are fitted into the recess 546. The supported portion 544 is formed by the rear surface 546b of the recess 546. The bottom surface 546a of the recess 546 is higher than the protruding portion 543a. The second engaging portion 545 is formed on the other end (front end) of the bottom wall 527 in the first direction. The second engaging portion 545 is formed on both ends in the second direction. Here, the second engaging portion 545 is provided using the leg portion 528 and is provided with a gap below the bottom surface 546a of the recess 546. In other words, a groove 545b (see Figure 9) is formed between the recess 546 and the second engaging portion 545.

[0040] As shown in Figure 10, the nozzle body 52 is composed of a cylindrical body 551, a connecting body 553 provided on the inlet side of the cylindrical body 551 and connected to the hose 57, a mounting body 555 for attaching the connecting body 553 to the cylindrical body 551, and a discharge port body 557 having an opening for forming the discharge port 511. Note that the connecting body 553 is placed inside the cylindrical body 551 after being connected to the hose 57, so it may also be part of the hose 57.

[0041] 4. Attaching the dispensing unit to the main body. (1) With the connection side of the main body 1 to the hose 57 facing upwards (one side in the first direction) and the discharge port 511 of the nozzle 51 facing downwards (the other side in the first direction), the protruding portion 543a of the guided portion 543 of the nozzle 51 is fitted into the guide groove portion 171 of the guide portion 107 of the main body 1. In other words, the first convex portion 173 and the second convex portion 175 of the main body 1 are fitted into the two recesses 546 of the nozzle 51 that are aligned in the second direction. This completes the alignment of the nozzle 51 with respect to the main body 1. In this case, since the protruding portion 543a of the nozzle 51 is provided in a straight line along almost the entire length of the nozzle 51, by fitting the protruding portion 543a of the nozzle 51 into the groove portion 163 of the support portion 106 on the upper side of the main body portion 1 and moving the nozzle 51 downwards, the protruding portion 543a can easily enter the guide groove portion 171 between the first protruding portion 173 and the second protruding portion 175.

[0042] (2) With the guided portion 543 of the nozzle 51 fitted into the guide portion 107 of the main body 1, the nozzle 51 is moved further downward. In this configuration, the lower part of the nozzle 51 is supported by the first protrusion 173 and the second protrusion 175, and the upper part is supported by the two protrusions 162. This allows the downward movement of the nozzle 51 to occur substantially parallel to the rear wall 12 of the main body 1, preventing the engaging portion 542 of the nozzle 51 (described later) from entering the first groove 151 of the main body 1 at an angle, and preventing the second engaging portion 545 of the nozzle 51 from disengaging from the third groove 181 of the main body 1.

[0043] (3) When the engaging portion 542 approaches the first groove 151 and the second engaging portion 545 approaches the third groove 181 from above (as shown in Figures 13(a1) and (b1)), and the guided portion 543 of the nozzle 51 is guided (fitted) by the guide portion 107 of the main body 1, when the nozzle 51 is moved downward, as shown in Figures 13(a2) and (b2), the engaging portion 542 enters the first groove 151 and the second engaging portion 545 enters the third groove 181. In this process, the convex portion 542c at the lower end of the engaging portion 542 of the nozzle 51 elastically deforms forward, and the protruding portion 157 within the recess 155 of the main body 1 elastically deforms backward.

[0044] (4) Furthermore, when the nozzle 51 is moved further downward while the guided portion 543 of the nozzle 51 is guided (fitted) by the guide portion 107 of the main body 1, as shown in Figures 13(a3) and (b3), the moving end (lower end) of the engaging portion 542 comes into contact with the bottom surface 151a of the recess 155 of the main body 1, or the rear side surface 546b (supported portion 544) of the recess 546 of the nozzle 51 comes into contact with the convex portion 161b (support portion 106) of the main body 1. As a result, with the extended portion 542a of the engaging portion 542 of the nozzle 51 inserted into the first groove 151 of the main body 1, the convex portion 542c of the engaging portion 542 of the nozzle 51 recovers from elastic deformation and fits into the second groove 153, making it difficult for the nozzle 51 to move upward relative to the main body 1. In this way, the nozzle 51 is attached to the main body 1 in a manner that makes it difficult to detach. Furthermore, in this state, the engaging portion 542 engages with the engaged portion 105 at the upper part of the nozzle 51, and the second engaging portion 545 engages with the second engaged portion (protruding portion 183) at the lower part of the nozzle 51. As a result, the nozzle 51 is attached to the main body 1 in a stable state.

[0045] 5. Dimensions The nozzle 51 has a trapezoidal or trapezoidal shape in a cross-section perpendicular to the first direction, where the upper base is smaller than the lower base. This improves the stability of the nozzle 51 when it is placed, for example, on a mattress. The second dimension L1 of the bottom surface portion (bottom wall 527) of the nozzle 51 facing the mattress is, when viewed from the bottom side, within a range of 1.5 to 2.9 times, preferably within a range of 1.7 to 2.7 times, the diameter D1 of the hose 57, as shown in Figure 14(a). This makes it less susceptible to the effects of movement of the comforter. In this example, the dimension L1 in the second direction is 84 mm and the diameter D1 of the hose 57 is 38 mm, but it is not necessary to limit the dimensions to these. When the nozzle 51 is attached to the rear part (rear wall 12) of the main body 1, as shown in Figure 14(b), the bottom surface covers more than 80% of the rear part. In other words, the projected area of ​​the bottom surface (bottom wall 527) is more than 80% of the projected area of ​​the rear part of the main body 1. This makes the bottom surface of the nozzle 51 larger relative to the rear part of the main body 1, making it less susceptible to the effects of movement of the comforter.

[0046] <Variation> Although an embodiment has been described, the invention is not limited to this embodiment, and may be modified in the following ways, for example. Furthermore, the embodiment may be combined with its modifications, or with other modifications. Furthermore, examples not described in the embodiments or modifications, as well as design changes that do not depart from the gist of the invention, are also included in the present invention.

[0047] 1. Main body (1) The dimensions of the main body 1 in the first direction are approximately the same as the dimensions of the nozzle 51 in the first direction (within the range of 0.9 to 1.1 times), however, if aesthetic considerations when the nozzle 51 is attached are not taken into account, they do not have to be approximately the same, and the dimensions of the nozzle 51 may be longer than 1.1 times the dimensions of the main body 1. This allows the hose 57 to be made longer. Furthermore, if the stability of the nozzle 51 during use is not a concern, the bottom portion may be positioned so that it covers less than 80% of the back portion when the nozzle 51 is attached to the main body 1. The back of the main body 1 is the mounting area for attaching the nozzle 51, but in the state shown in Figure 1(a), one side in the second direction (right side or left side) may also be the mounting area for the nozzle 51. In this case, the direction in which the main body 1 and the nozzle 51 are adjacent becomes the third direction, and the operating unit 40 will be provided on the right side or left side.

[0048] (2) The operating unit 40 was provided on the front wall 11, but it may also be provided across the right wall 13, the left wall 14, the front wall 11 and the left wall 14, or the front wall 11 and the right wall 13. The operating unit 40 has an operating control unit, but the operating control unit may be provided in the circuit unit 30. (3) The hot air supply unit 20 is equipped with the air blowing means 21 on the upstream side and the heating means 22 on the downstream side, but the reverse is also acceptable. However, considering the heat resistance of the air blowing means 21, it is preferable to have the air blowing means 21 on the upstream side. In the hot air supply unit 20, the inlet opening 232 of the casing 23 and the intake port 16a of the housing 10 were arranged in close proximity in the first direction, but they may be spaced apart. However, when air from outside the housing 10 is directly drawn into the hot air supply unit 20, the distance between the inlet opening 232 and the intake port 16a is preferably less than or equal to the maximum dimension of the intake port 213a, considering smooth suction. (4) The hot air supply unit 20 had the inlet opening 232 of the casing 23, the suction port 213a of the air blowing means 21, the heating means 22, and the outlet opening 233 on the rotation axis (straight line) of the air blowing means 21, but these may also be arranged in this order on a gently curving line. In this case as well, air can be drawn in and discharged smoothly. (5) The hot air supply unit 20 was equipped with a connector 25 for connecting to the hose 57, but the connector 25 may be rotatably fixed directly to the housing 10. Considering assembly efficiency, it is preferable to have a structure in which the hot air supply unit 20 and the discharge unit 5 are connected by the hose 57 and then assembled into the housing 10. (6) The electronic components 31 of the circuit unit 30 may be mounted on the circuit board 43 of the operation unit 40 to form a single circuit section (a single circuit board). The circuit board 32 of the circuit unit 30 was positioned close to the left wall 14 and approximately parallel to the left wall 14, but it may also be positioned close to the rear wall 12 and parallel to the rear wall 12. However, considering assembly efficiency, it is preferable to provide the circuit board 32 on the housing body 101 side.

[0049] (7) The guide groove 171 of the guide portion 107 is formed between the first protrusion 173 and the second protrusion 175, and is groove-shaped based on the protruding tips of the first protrusion 173 and the second protrusion 175 (the rear wall 12 itself is not recessed). However, the guide groove may be provided with a groove recessed into the rear wall 12 on the front side in the third direction, without the first protrusion 173 and the second protrusion 175, or it may be provided with the first protrusion 173 and the second protrusion 175, and also with a groove in the rear wall 12. (8) The first protruding portion 173 may protrude in a frame-like manner (the inside of the frame may not protrude), but the entire portion may protrude (the inside of the frame may also protrude in the same way). (9) The second protruding portion 175 had a second forward protruding portion 175a and a second backward protruding portion 175b, but it may also be made up of only the second forward protruding portion 175a (which needs to protrude more by the amount of the second backward protruding portion 175b) without the second backward protruding portion 175b, or conversely, it may be made up of only the second backward protruding portion 175b which protrudes in a frame shape, like the first protruding portion 173 (which needs to protrude more by the amount of the second forward protruding portion 175a).

[0050] 2.Discharge part (1) The nozzle 51 has a support portion 521 on the side other than the center in the first direction of the nozzle body 52, but the support portion 521 may be at the center in the first direction, or on one side of the center in the first direction. If the longitudinal length of the support member 53 (length in the first direction in the closed state) is to be increased, it is better for the support portion 521 to be on the other side in the first direction. (2) The angle A between the first direction and the third direction, which is the rotation range of the support member 53 (see Figure 11), was 110° in the embodiment, but if the angle is 90° or more, the load of the weight of the item to be dried (e.g., a comforter) will act in the direction of opening the support member 53, and the closing of the support member 53 can be suppressed. The angle A between the first direction and the third direction should be 130° or less, preferably 120° or less. By keeping it within this range, the load (torque) of the object being dried acting on the support part 521 and the supported part 533 can be reduced. The angle A between the first direction and the third direction may be 90° or less, in which case it can be implemented by providing a restricting part (a first auxiliary support part that supports from the closed side in the direction of rotation) that restricts rotation in the closing direction. (3) The support member 53 is rotatably supported by the support portion 521, but it may be configured to be detachable between the open and closed states. For example, this can be done by providing a closing support groove along the first direction and an opening groove along the third direction in the nozzle body 52, and inserting and removing the support member. (4) In the closed state (the state in which the support member 53 is supported by the support portion 521 so as to extend in the first direction), the support member 53 is configured such that one end (rear end) in the first direction is located on the other side of the one end of the nozzle body 52 in the first direction. However, the support member 53 may be configured so that one end (rear end) extends further in the first direction than one end of the nozzle body 52. ​​This makes the support member 53 longer in the first direction, for example, making the space between the mattress and the comforter larger.

[0051] 3. Regarding nozzle attachment (1) In this embodiment, the main body 1 had an engaged portion 105 and the nozzle 51 had an engaging portion 542, but the engagement relationship may be reversed.
