  Next, embodiments will be described with reference to the drawings. In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals.

  In addition, the embodiments described below exemplify apparatuses and methods for embodying the technical idea, and do not specify the material, shape, structure, arrangement, etc. of the component parts as follows. . This embodiment can be modified in various ways within the scope of the claims.

[Overall configuration]
Referring to FIG. 1, a drying apparatus according to an embodiment is generally indicated by reference numeral 10. The drying apparatus 10 includes a main body 12 and a pedestal portion 14 that supports the main body 12.

  As shown in FIG. 2, the main body 12 of the drying apparatus 10 includes a housing 16, a propeller-type fan 18 housed in the housing 16 that is rotationally driven, and a drive source 20 that includes a scraping motor for rotationally driving the fan 18. And a heat source 22 supported by the housing 16.

[housing]
The housing 16 includes a wind tunnel portion 24 and a bowl-shaped guard portion 26. The wind tunnel portion 24 and the guard portion 26 are connected to each other in a state where the open end of the wind tunnel portion 24 and the open end of the guard portion 26 face each other.

[Wind tunnel and guard]
The wind tunnel portion 24 has a cylindrical surface 24 a that defines a passage of air flow generated by the rotation of the fan 18, and the guard portion 26 has a plurality of gaps 26 a (FIG. 1) that allow inflow of outside air into the guard portion 26. The fan 18 is disposed in the wind tunnel portion 24 coaxially therewith. The drive source 20 is disposed in the guard part 26 and is fixed to the guard part 26. The guard unit 26 has a function of protecting the driving source 20 inside and protecting a person who uses the drying device 10.

[Fan and drive source]
The illustrated fan 18 is a so-called double fan (see FIGS. 10 and 11) having a large-diameter fan 64 and a smaller-diameter fan 66 arranged in series on a common axis and spaced from each other. Thus, the large-diameter fan 64 and the small-diameter fan 66 are positioned at the rear and front in the moving direction of the airflow flowing through the wind tunnel portion 24, respectively. The double fan will be described later. The fan 18 may be composed only of the large-diameter fan 64 instead of the illustrated example. The fan 18 is rotatably supported around the axis L1 (FIG. 4) of the wind tunnel portion 24 in the wind tunnel portion 24 via the drive shaft 20a of the drive source 20 connected to the hub 64a of the large-diameter fan 64. ing.

  When the fan 18 is rotationally driven under the power of the drive source 20, outside air is drawn into the wind tunnel portion 24 through the guard portion 26 from the gap 26 a of the guard portion 26, and an air flow is generated in the wind tunnel portion 24. The air flow moves from one open end (inlet) 24b of the wind tunnel part 24 toward the other open end (exit) 24c, and then is discharged to the outside of the wind tunnel part 24 through the outlet 24c. In the illustrated example, the wind tunnel portion 24 has a conical surface 24d that is continuous with the cylindrical surface 24a and extends toward the inlet 24b. Therefore, the inlet 24b consists of the open end of the conical surface 24d, and the outlet 24c consists of the open end of the cylindrical surface 24a.

  The air flow released to the outside is applied to clothes, dried fish, for example, paint applied to an object such as a wall, etc., to be dried by the drying apparatus 10. In order to prevent intrusion of dust and dust into the wind tunnel portion 24 and outflow to the outside of the wind tunnel portion 24, mesh panels (not shown) that allow the passage of outside air and air flow at the inlet 24b and the outlet 24c of the wind tunnel portion 24, respectively. )). The fan 18 may be disposed inside the guard portion 26 outside the wind tunnel portion 24 instead of the illustrated example.

[Sending part]
The illustrated housing 16 further includes a delivery portion 32 (see FIGS. 7 to 9) connected to the wind tunnel portion 24 at its outlet 24 c and communicating with the wind tunnel portion 24. The delivery part 32 has a cylindrical inner peripheral surface 32a that exerts a delivery action in the direction of extension of the axis L1 of the wind tunnel part 24 on the airflow discharged from the outlet 24c of the wind tunnel part 24 (FIGS. 3 to 3). 6). As shown in FIG. 8, the delivery part 32 has four plate-like sag 32b arranged around the periphery thereof, and the wind tunnel part 24 is provided around the periphery thereof. It has four ribs 24e extending in the axial direction. Each sag 32b and each rib 24e are fixed so as to be releasable via fastening means such as screws, whereby the delivery part 32 is connected to the wind tunnel part 24.

[Heat source]
The heat source 22 is outside the wind tunnel portion 24 and is opposed to the outlet 24 c of the wind tunnel portion 24. The illustrated heat source 22 is made of a nichrome wire that generates heat when energized. The nichrome wire is spirally formed around the two heat-resistant plate pieces 34 combined so as to cross each other in a cross shape, and the diameter gradually increases from the rear to the front with respect to the moving direction of the air flow. It is rolled up.

[Cylinder]
Further, a heat-resistant cylinder 36 around which the heat source 22 and the plate piece 34 are surrounded and the plate piece 34 is fixed is disposed. The cylinder 36 extends in the extending direction of the axis L <b> 1 of the wind tunnel portion 24. The cylinder 36 receives a part of the air flow discharged from the outlet 24c of the wind tunnel part 24 and allows a part of the air flow to move. A part of the air flow contacts the heat source 22 while moving in the cylinder 36, and is released to the outside of the cylinder 36 in a heated state.

  Therefore, a part of the air flow is blown out from the cylinder 36 as hot air, and the other part is around the cylinder 36, more precisely around the cylinder 42 described later that accommodates the cylinder 36. It is blown out as cold air from the outlet 24c. Both the hot air and the cold air flow in the extending direction of the axis L1 of the wind tunnel portion 24. Since the hot air discharge position (the open end of the cylinder 36) is in front of the cold air discharge position (the outlet 24c of the wind tunnel 24) with respect to the moving direction of the airflow, They are mixed outside the wind tunnel 24 and the cylinder 36 that define the flow path. As a result, hot air and cold air are mixed relatively uniformly and efficiently, and reach the object to be dried. Mixing hot air and cold air, that is, mixed air efficiently dries the object to be dried. The temperature of the mixed air is determined in consideration of the wetness of the object to be dried and the ambient environmental temperature, and the temperature of the heat source 22 is adjusted to obtain the desired temperature of the mixed air. Further, the flow rate of the mixed air can be adjusted by changing the rotation speed of the fan 18, that is, the operation speed of the drive source 20.

  As described above, the drying apparatus 10 according to the embodiment generates a moderately warmed air flow (mixed air) and sends it out, and includes a heat pump necessary for generating a dehumidified air flow. Absent. For this reason, the drying apparatus 10 can be made relatively small in weight, and the form of the drying apparatus 10 can be made relatively compact. For this reason, the handling of the drying device 10 is relatively easy, and the cost required for manufacturing the drying device 10 is relatively low.

  The axis of the heat source 22, more specifically, the cylinder 36 is located on the extension of the axis L1 of the wind tunnel 24, that is, in front of the center of the circular outlet 24c of the wind tunnel 24 (the front in the moving direction of the air flow). . However, instead of the illustrated example, it is possible to arrange the cylinder 36 in which the heat source 22 is arranged in front of a position other than the center part of the outlet 24c. This is advantageous in increasing the degree of mixing of cold air.

  At the open ends of the cylinder 36, as in the wind tunnel portion 24, dust enters the cylinder 36, and when dust enters the cylinder 36, the debris is discharged outside the cylinder 36 due to contact with the heat source 22. Are covered with mesh panels 38 and 40 (see FIG. 2, FIG. 6 and FIG. 7) that allow the passage of air flow, respectively.

  In the illustrated example, the cylinder 36 in which the heat source 22 is arranged is held in the cylinder 42, and the cylinder 36 is seated on the mesh panel 38.

[Cylinder]
The cylindrical body 42 includes a cylindrical portion 44 and a bulging portion 46 connected to the cylindrical portion (see FIG. 5). The bulging portion 46 is tapered toward the front in the moving direction of the air flow.

  According to this, a part of the cold air blown from the outlet 24c of the wind tunnel portion 24 flows along the bulging portion 46, and the cold air is heated to the hot air blown from the cylinder 36 in the cylindrical body 42 at the foremost position. collide. According to this, mixed air of warm air and cold air having a relatively high degree of mixing can be obtained. The bulging portion 46 may be provided in the entire periphery of the cylindrical portion 44 instead of the illustrated example provided in a part of the periphery of the cylindrical portion 44. In this case, for example, the bulging portion 46 defines a truncated conical surface that surrounds the periphery of the cylindrical portion 44 and gradually decreases in diameter toward the front in the moving direction of the air flow.

  A control member 47 made of a bimetal, a thermostat, or the like for controlling overheating of the heat source 22 is disposed in a space existing between the cylindrical portion 44 and the bulging portion 46. By using the space between the cylindrical portion 44 and the bulging portion 46 as the arrangement space for the control member 47, the drying apparatus 10 itself can be made compact. Reference numeral 49 denotes a lid formed in the bulging portion 46 for closing an opening (not shown) for taking in and out of the control member 47.

[Holding cylinder]
The delivery part 32 which comprises the housing 16 has the holding cylinder 48 which penetrates the center part (refer FIGS. 7-9). The holding cylinder 48 has a cylindrical space 48 </ b> A that receives a part of the cylindrical part 44 of the cylindrical body 42, and a gap 48 </ b> B that receives a part of the bulging part 46. The holding cylinder 48 is supported at the center of the delivery unit 32 via a plurality of elongated support bones 51. The plurality of support bones 51 are arranged at a distance from each other on one virtual plane, and each of the support bones 51 is curvedly extended in an arc shape from the inner peripheral surface 32a (FIG. 1) of the delivery portion 32 to the holding cylinder 48. The holding cylinder 48 has one end 48 a extending in the wind tunnel 24 and the other end 48 b protruding to the cylinder 42 side. The supporting bone 51 can be extended linearly or with another curved form instead of the illustrated example. The cold air flows between the support bones 51.

  The cylindrical body 42 is formed with two pins 50 (FIG. 7) extending in the axial direction from the open end covered with the mesh panel 38. On the other hand, the holding tube 48 is formed with two guide grooves 52 (FIG. 9) extending in the axial direction. Each guide groove 52 has an open end 52 a that allows insertion of each pin 50, and another end 52 b that stops each inserted pin 50. When both pins 50 are respectively inserted into the guide grooves 52 from their open ends 52a and stopped at the other end 52b, a part of the cylindrical part 44 of the cylindrical body 42 and a part of the bulging part 46 are formed on the holding cylinder 48. The cylindrical space 48A and the gap 48B are received respectively. At this time, the mesh panel 38 of the cylinder 42 is located on a virtual plane including the outlet 24c of the wind tunnel portion 24 (see FIG. 2).

[Groove for holding lead wire]
Preferably, one or more (two in the illustrated example) of the plurality of support bones 51 of the holding cylinder 48 are extended to the support bone 51A (FIG. 9) in the extending direction of the support bone 51A and the wind tunnel portion. A groove 54 that opens toward 24 is provided. The groove 54 can be used as a space for arranging lead wires (not shown) for supplying power to the heat source 22. According to this, it is possible to avoid that the lead wire is disposed so as to cross between the support bones 51 and that the lead wire becomes a flow resistance against the air flow. Further, by making the supporting bone 51A bend and extend as in the illustrated example, the lead wire may be less likely to drop out of the groove 54 than when the supporting bone 51A extends linearly. it can.

[Interconnection of wind tunnel and guard]
As shown in FIG. 8, the wind tunnel portion 24 in which the fan 18 is disposed and the guard portion 26 in which the drive source 20 of the fan 18 is disposed can be connected to each other by two different connection means. According to this, even when a failure occurs in one of the connection means, the connection state between the wind tunnel portion 24 and the guard portion 26 can be maintained with the other connection means. Unexpected separation between the wind tunnel portion 24 and the guard portion 26 due to movement for changing the arrangement position, accidental contact of the user with the drying apparatus 10, collision, and the like, and the accompanying fan 18 and fan 18 Breakage of the connection structure with the drive source 20 can be prevented.

  One connection means includes a plurality of claw members 56 that are elastically deformable. These claw members 56 are arranged around the wind tunnel portion 24 at intervals, and extend from the wind tunnel portion 24 toward the guard portion 26. When each claw member 56 is placed on the guard part 26 with the wind tunnel part 24 partially fitted to the guard part 26, the claw member 56 is elastically deformed and moves in the guard part 26 toward the gap 26a. Then, when it reaches the gap 26a, it elastically recovers and locks to the guard portion 26, more specifically, to the belt-like portion 26b that defines the open end of the guard portion 26, whereby the wind tunnel portion 24 and the guard portion 26 are connected. It is put into a state (refer FIG. 1).

  The other connecting means includes a plurality of (three in the illustrated example) semi-circular holes 58 that are open toward the guard portion 26 that are provided at intervals around the wind tunnel portion 24, and a guard. The portion 26 includes a plurality of circular holes 60 having the same number as the holes 58 and a button-shaped locking member 62 having the same number as the holes 60. In this connection means, when the wind tunnel portion 24 is placed on the guard portion 26 in a state of being partially fitted to the guard portion 26, the holes 58 and the holes 60 are aligned with each other. Next, when the locking member 62 is passed from each hole 60 to each hole 58 and the locking member 62 is rotated 90 degrees in the illustrated example, the locking member 62 is locked to the inner peripheral surface of the wind tunnel portion 24. More specifically, the locking claw 62 a provided at the tip of the locking member 62 is elastically deformed and firmly contacts the inner peripheral surface of the wind tunnel portion 24. As a result, the wind tunnel portion 24 and the guard portion 26 are fixed to each other and thereby connected to each other.

  Interconnection between the wind tunnel portion 24 and the guard portion 26 by these two connecting means and release thereof can be performed relatively easily. For this reason, it is possible to relatively easily separate and reconnect the wind tunnel portion 24 and the guard portion 26 when performing the maintenance of the drying apparatus 10. Note that the claw member 56 in the one connection means and the hole 58 and the hole 60 in the other connection means are arranged at different positions with respect to the circumferential direction of the wind tunnel portion 24 and the guard portion 26.

[Fan structure]
With respect to the fan 18 disposed in the wind tunnel portion 24, preferably, as shown in FIG. 2, the hub 64a of the large-diameter fan 64 is positioned near the cylindrical portion 44 of the cylindrical body 42 in which the heat source 22 is accommodated. In addition, the outer diameter of the hub 64 a of the large-diameter fan 64 is substantially equal to the inner diameter of the cylindrical portion 44 of the cylindrical body 42 or the inner diameter of the cylinder 36 surrounding the heat source 22. According to this, the hub 64 a of the large-diameter fan 64 prevents a part of the air flow from flowing into the cylinder 36. For this reason, the inflow amount of a part of the air flow into the cylinder 36 can be limited, and thereby the velocity of the warm air flowing out to the outside through the cylinder 36 flows out through the outlet 24c of the wind tunnel portion 24. It can be set to be smaller than the speed of the cold air. For example, the outflow speed of hot air and the outflow speed of cold air can be set to, for example, about 2 m / sec and about 5 m / sec, respectively. By setting in this way, the mixing degree of warm air and cold air can be further increased, and the mixed air can be sent further away.

  Preferably, the outer diameter of the small-diameter fan 66 is substantially equal to the outer diameter of the hub 64a of the large-diameter fan 64. More preferably, a part of the small-diameter fan 66 is located in the one end 48 a of the holding cylinder 48. (See FIGS. 2 and 11). According to this, an air flow having a different flow rate and flow velocity from the air flow generated by the large-diameter fan 64 can be generated and fed into the cylinder 36. In the illustrated example, the large-diameter fan 64 and the small-diameter fan 66 have three blades 64b and three blades 66b, respectively, but the number of blades 64b and blades 64b may be set differently from the illustrated example. it can. In the illustrated example, the three blades 64b and the three blades 66b are arranged in phase around the common axis of the hub 64a and the hub 66a. Instead, as shown in FIG. 12, the three blades 64b and the three blades 66b can be arranged so that there is an arbitrary phase difference of, for example, 30 degrees around the common axis.

  As shown in FIG. 11, the large-diameter fan 64 and the small-diameter fan 66 can be connected to each other in the following manner.

  The hub 64a of the large-diameter fan 64 has two recesses 68 and 70 that open in opposite directions with respect to the common axis, and two protrusions 72 and 74 that extend in opposite directions within the recesses 68 and 70 on the common axis. With. Since both protrusions 72 and 74 extend in the two recesses 68 and 70, respectively, the protrusion amount of both protrusions 72 and 74 from the hub 64a is made relatively small, thereby the common axis of the large-diameter fan 64 itself. The length in the direction can be kept relatively small. On the other hand, the hub 66 a of the small-diameter fan 66 includes a protrusion 78 having a hole 76 that extends on the common axis toward the recess 70 of the large-diameter fan 64.

  One protrusion 72 of the large-diameter fan 64 has a hole 80 that receives the drive shaft 20 a of the drive source 20. The hole 80 of the protrusion 72 and the drive shaft 20a received in the hole 80 and the drive shaft 20a have a common D-shaped cross-sectional shape so that the protrusion 72 and the drive shaft 20a can be integrally rotated. . Further, the other projection 74 of the large-diameter fan 64 is press-fitted into the hole 76 of the projection 78 of the small-diameter fan 66, and thereby the large-diameter fan 64 and the small-diameter fan 66 are firmly connected so as to be integrated. ing. Therefore, a special connecting member for connecting the large-diameter fan 64 and the small-diameter fan 66 to each other is not required. Further, the large-diameter fan 64 and the small-diameter fan 66 can be interconnected relatively easily. Further, the cost required for manufacturing the fan 18 can be made relatively low.

[Oscillation and rotation of the body]
The drying apparatus 10 is preferably configured such that the main body 12 is swingable with respect to the pedestal portion 14 in the direction of an arrow a around an axis L2 (FIG. 4) perpendicular to the axis L1 of the wind tunnel portion 24. It can rotate around the axis L3 (FIG. 4) of the pedestal portion. According to this, it is possible to change the swing position, that is, the elevation angle and the rotation position of the main body 12, and thereby the direction of the mixed air to be discharged can be changed.

  The swinging range of the main body 12, that is, the range of the angle swinging around the axis L2, is preferably from the angle (0 degree) at which the main body 12 is in a horizontal state (not shown) (see FIG. 3). And FIG. 4) is set to a range up to an angle (90 degrees). FIG. 1 shows a state in which the main body 12 is swung by an angle of 45 degrees around the axis L2 from the horizontal state or the vertical state. The range of angles at which the main body 12 rotates around the axis L3 of the pedestal portion 14, that is, the so-called swing angle range, is preferably set to a range of 0 to 90 degrees.

[Main body and pedestal]
In order to make the main body 12 swingable about the axis L2 and to be rotatable about the axis L3, as shown in FIG. 13, the main body 12 has a pedestal portion via a pair of plate-like leg members 82. 14 is supported. Further, the pedestal portion 14 includes a disc-shaped stationary portion 14a and a movable portion 14b connected to the stationary portion so as to be rotatable in the circumferential direction (see FIGS. 2, 3, and 7). .

  The both leg members 82 extend from the movable portion 14b of the pedestal portion 14 into the guard portion 26 through two elongated openings 84 provided in the guard portion 26 and extending from the side surface of the guard portion 26 toward the bottom surface. It is fixed to the drive source 20 inside.

  Further, as shown in FIG. 4, two disk-shaped members 86 that are rotatably supported around the axis L <b> 2 in the guard portion 26, and are opposed to each other by the disk-shaped members 86 in the radial direction. A pin member 88 having a spherical head portion, which is movably attached, and a coil spring 90 to be compressed that exerts a spring force on the pin member 88 in the axial direction thereof are arranged.

  Further, the arc-shaped member 92 is disposed concentrically at a distance from the peripheral surface of each disk-shaped member 86 in the guard portion 26 and is fixed to the distal ends of the both leg members 82. The arc-shaped member 92 has a plurality of hemispherical depressions 94 that are intermittently arranged in the circumferential direction and open toward the disk-shaped member 86. Furthermore, a part 26c on the bottom surface of the guard part 26 and a part 96 on the top surface of the movable part 14b of the pedestal part 14 opposite to each other define two arc surfaces having the same curvature.

  According to this, the main body 12 can be manually swung around the axis L2 together with the disk-shaped member 86. At this time, each disk-shaped member 86 rotates relative to the arc-shaped member 92, and the head portion of the pin member 88 receiving the spring force from the coil spring 90 is one depression 94 in the arc-shaped member 92. It moves from inside into another indentation 94 adjacent to it. At this time, the moved position is maintained. When the main body 12 is swung, both the leg members 82 move relatively in the openings 84 of the guard portion 26 in the extending direction of the openings. Further, a part 26c of the bottom surface of the guard part 26 moves in the direction of arrow a along a part 96 of the top surface of the movable part 14b of the pedestal part 14 facing the guard part 26.

  The pedestal portion 26 includes a drive source 98 (see FIG. 2) composed of an electric motor that gives rotational power to the movable portion 14b. The drive source 98 is supported by the stationary part 14a, and the drive shaft 100 is connected to the movable part 14b. The main body 12 rotates around the axis L <b> 3 of the pedestal portion 26 together with the movable portion 14 b of the pedestal portion 14 by operating the drive source 98.

[cover]
The main body 12 preferably includes a cylindrical cover 102 that protects the wind tunnel portion 24 and more preferably the delivery portion 32. The cover 102 sequentially passes the delivery part 32 and the wind tunnel part 24 of the housing 16 through the inside thereof, so that the air gap H (see FIG. 4) is provided around the wind tunnel part 24 and the delivery part 32 between the wind tunnel part 24 and the delivery part 32. ) And can be arranged to surround. The cover 102 can be fixed to the guard portion 26.

  Since there is a gap H between the cover 102 and the wind tunnel 24 and the delivery part 32, the cover 102 undergoes elastic deformation or plastic deformation when it receives an external force, so Protect these against external forces. This prevents the shape of the air flow passage defined by the wind tunnel 24 or the air flow delivery path defined by the delivery portion 32 from changing.

[Operation board]
On the surface of the cover 102, an operation panel 106 provided with a plurality of operation buttons 104 for performing operations such as operation of the drying apparatus 10, switching of the air volume and wind speed, setting of a timer, and the like is attached ( FIG. 1). The operation button 104 is disposed on a flat surface 102a (FIG. 4) formed on a part of the surface. The operation panel 106 is preferably attached at a position where the operation panel 106 faces upward when the main body 12 is swung around the axis L2 between the horizontal state and the vertical state. For this reason, the operation panel 106 can be placed in a range that is visible to the user of the drying apparatus 10 and in an easily operable state.

  Further, the operation panel 106 is disposed around the wind tunnel portion 24 at a position above the guard portion 26 that exerts an outside air suction action. For this reason, when a user touches the operation panel 106, the danger that a part of a user's hair and clothing will be drawn into the guard part 26 through the clearance 26a of the guard part 26 can be reduced.

  Further, an operation member 107 (FIG. 4) connected to the operation button 104 of the operation panel 106 is accommodated in a gap H between the cover 102 and the wind tunnel portion 24. This contributes to making the drying apparatus 10 compact.

[Toride]
