  As shown in FIGS. 1 and 2, the drying device 1 includes a housing 3 having a substantially rectangular parallelepiped shape having suction ports 200 a to 200 c and a discharge unit 51.

  The housing 3 includes a housing main body 30 and a lid member 31. Although the detailed configuration is omitted, an operation panel 35 is disposed on the front side of the lid member 31. Further, a control board (not shown) is arranged on the back surface side of the lid member 31.

  In a state where the housing 3 is upright (see FIG. 1A), a handle 36 used when carrying the drying apparatus 1 is formed above the housing main body 30 and the lid member 31.

  As shown in FIG. 2, inside the housing 3, a sirocco fan 300 (see FIG. 7 described later) that discharges air sucked from the intake ports 200 a to 200 c from the discharge unit 51, and the sirocco fan 300 and the discharge unit 51 are provided. And a motor M as a driving source of the sirocco fan 300 are housed.

  Note that, inside the housing 3, there is provided an air blowing means including a sirocco fan 300 and a scroll-shaped casing C that covers the sirocco fan 300 (see FIG. 8 described later).

  Further, the discharge unit 51 is a cylindrical body connected to the upper part of the housing 3 and is configured to discharge the wind obtained by the blower to the outside.

  One end of the hose 5 is connected to the discharge unit 51. The hose 5 has a bellows-like configuration having flexibility, and is stored in a bent state as shown in FIG. 1 and the like when the drying device 1 is not used. The hose 5 is used in a state of being raised and extended in the direction D2 as shown in FIG.

  Instead of the flexible hose 5 as described above, a solid pipe-like material formed of inflexible metal or resin may be used.

  The other end of the hose 5 is provided with a nozzle body 150 that blows out the air supplied from the discharge unit 51. When the drying apparatus 1 is not used, the nozzle main body 150 is mounted on a part of the housing 3 as shown in FIG. 1 and the like, and is housed.

  The nozzle body 150 is not limited to the configuration connected to the end of the hose 5, but may be configured to be directly connected to the housing 3, or may be configured to be connected to the tip of a solid pipe as described above. Is also good.

  The discharge unit 51, the hose 5, and the nozzle body 150 constitute a discharge unit that discharges heated air while being covered with the object to be dried by being inserted between objects to be dried such as a futon. ing.

  When the futon is dried, it is sufficient that at least the nozzle body 150 is covered with an object to be dried such as a futon, and it is not always necessary to insert the discharge unit 51 and the hose 5 into the futon.

  Further, the nozzle body 150 is provided with a space expanding mechanism that lifts the object to be dried and expands a reaching space of heated air in a state where the nozzle body is covered with an object to be dried such as a futon. I have.

  The space expansion mechanism includes, for example, a movable unit 152 described later provided in the nozzle body 150.

  Here, in the drying state of the object to be dried by the drying device 1, the heated air is sequentially fed through the nozzle body 150, and gradually escapes from the gap of the object to be dried such as a futon with the passage of time. Will go. The “arrival space” in the present embodiment refers to a space in which the air thus sent through the nozzle body 150 temporarily stays until it escapes to the outside. That is, the “reachable space” can be said to be a substantially closed space formed around the nozzle body 150 by the object to be dried when the discharge unit is inserted into the object to be dried.

  As shown in FIG. 1B, FIG. 3 and FIG. 4, a first protrusion 130 formed along the outer periphery of the casing C is provided on the back side of the housing 3. Further, a second protrusion 131 extending in the left-right direction is formed at a position separated from the first protrusion 130 in the ventilation direction.

  In the housing 3, a heater H as a heating unit is disposed at a position P corresponding to between the first protrusion 130 and the second protrusion 131. In addition, the first protrusion 130 and the second protrusion 131 are configured to have the same amount of protrusion to the rear side.

  With such a configuration, when the drying device 1 is used with the rear side of the housing 3 placed on a material to be dried such as a floor or a futon, the first projection 130 and the second projection are used. A space is formed at a position P corresponding to between 131. Since the heat is radiated through the housing 3 through this space, an excessive temperature rise of the heater H can be suppressed. Note that a heat insulating material (for example, a heat insulating sheet or the like made of aluminum tape containing glass fiber) 401 is interposed between the heater case 400 that covers the heater H and the housing 3 (see FIG. 3 and later). 8), the heat transfer to the housing 3 can be suppressed.

  In addition, as shown in FIGS. 1, 3, and 4, the drying apparatus 1 according to the present embodiment has a left and right side of the housing body 30 in addition to a bottom surface air inlet 200a formed on the bottom surface of the housing body 30. It has two side intake ports 200b and 200c formed on the side surfaces.

  Thereby, the air intake efficiency can be increased, the amount of air discharged from the nozzle body 150 can be increased, and the drying efficiency can be improved.

  Further, since the air inlets 200a to 200c are provided in three directions of the drying device 1, the operation panel 35 as shown in FIG. 1A is upright and the operation panel 35 as shown in FIGS. In addition to the state (so-called futon drying state), sufficient suction can be performed in the use of the three types of states (so-called side-down state) in which the side air intake port 200c is placed so as to face upward.

  It is to be noted that a usage state in which the side intake port 200b is upward is not assumed. This is because it becomes difficult to send sufficient air around the motor M to cool it.

  In order to prevent such a use state beforehand, an inclination sensor (inclination switch) is provided on a control board (not shown) or the like, and when an inclination such that the side intake port 200b is upward is detected. And a safety mechanism for turning off the power of the heater H and the like.

(Configuration of nozzle body and space expansion mechanism)
With reference to FIGS. 5 and 6, the configuration and operation of the nozzle unit 151 and the movable unit 152 that configure the nozzle body 150 and the space expansion mechanism will be described.

  FIG. 5A is a perspective view showing a closed state of a movable unit 152 constituting a main part of a nozzle body 150 of the drying apparatus 1 according to the embodiment, and FIG. 5B is a view showing an opened state of the movable unit 152. FIG.

  FIG. 6A is a side view illustrating the closed state of the movable unit 152 of the drying device 1, and FIG. 6B is a side view illustrating the opened state of the movable unit 152.

  The nozzle main body 150 includes a nozzle unit 151 disposed on the distal end side of the hose 5 and a movable unit 152 provided in the nozzle unit 151.

  As shown in FIGS. 5 and 6, a front outlet 170 as a main outlet is provided at the front end (left end in FIGS. 6A and 6B) of the nozzle unit 151. It should be noted that the front outlet 170 can be provided with optional items such as an attachment used for drying shoes and an aroma case for emitting fragrance.

  Further, a plurality of slit-shaped auxiliary outlets 180 are provided on the left and right side surfaces of the nozzle unit 151. Thereby, in addition to the airflow from the front outlet 170, the airflow can be discharged from the auxiliary outlet 180, and the drying efficiency of a material to be dried such as a futon can be improved. The auxiliary outlet may be provided on the upper surface of the nozzle unit 151.

  At the rear end of the nozzle unit 151 (the right end in FIGS. 6A and 6B), a connection portion 160 that is rotatably connected to the hose 5 is provided. That is, the rear end of the nozzle unit 151 is parallel to the direction of air flow of the nozzle unit 151 with respect to the hose 5, that is, the direction from the hose 5 to the main outlet 170 (the Z direction in FIGS. 6A and 6B). It is connected rotatably about a suitable axis. Thereby, the nozzle main body 150 can be installed in a direction most suitable for drying with respect to an object to be dried such as a futon, and a situation in which the hose 5 is twisted by the direction of the nozzle main body 150 can be avoided.

  The movable unit 152 constituting the space expansion mechanism is provided so as to be able to change its attitude with respect to the nozzle unit 151.

  More specifically, the movable unit 152 is held along the extended state (see FIG. 5B and FIG. 6B) extended in a direction perpendicular to the ventilation direction and along the nozzle unit 151. It is configured such that it can be selectively changed to a housed state (see FIG. 5A and FIG. 6A).

  Note that the extending direction of the movable unit 152 is not limited to the direction orthogonal to the ventilation direction, and may be any direction as long as it intersects with the ventilation direction.

  In the configuration examples shown in FIGS. 5 and 6, the movable unit 152 moves the nozzle unit 151 relative to the nozzle unit 151 in the direction of arrow D1 (FIG. 5B ) And FIG. 6 (b)).

  In the housed state, the movable unit 152 includes an upper plate portion 152a that covers at least a part of the upper surface of the nozzle unit 151, and side plate portions 152b and 152c that cover both side surfaces of the nozzle unit 151.

  The side plate portions 152b and 152c are pivotally supported on the side surface of the nozzle unit 151 by a rotation shaft 155.

  More specifically, a protruding rotating shaft 155 is integrally formed inside the side plate portions 152b and 152c (see FIG. 5B), and an engagement formed on a side wall of the nozzle unit 151. The tip of the rotation shaft 155 is rotatably engaged with a hole (not shown).

  The nozzle unit 151 and the movable unit 152 hold the movable unit 152 in the housed state (the state of FIGS. 5A and 6A) and extend the movable unit 152 (FIG. 5B 6) and FIG. 6B).

  Here, a configuration example of the stopper mechanism will be described with reference to FIG.

  FIG. 10A is a partial perspective view of a nozzle unit 151 showing a configuration example of a stopper structure provided in the drying device 1, and FIG. 10B is a perspective view of the back side of the movable unit 152.

  As shown in FIG. 10A, two protrusions 901a and 901b for stopper are formed on the periphery of the bearing 157 of the rotation shaft located on the rear end side of the nozzle unit 151 in the drawing.

  On the other hand, as shown in FIG. 10B, the peripheral surface of the rotation shaft 155 of the movable unit 152 rotatably engaged with the nozzle unit 151 is locked by the projections 901a and 901b on the nozzle unit 151 side. Possible projections 902 are integrally formed.

  When the movable unit 152 is housed, the protrusion 902 on the movable unit 152 side is locked by the protrusion 901a on the nozzle unit 151 side. When the movable unit 152 is in the extended state, the projection 902 on the movable unit 152 side is locked by the projection 901b on the nozzle unit 151 side.

  In this way, the movable unit 152 is held by the stopper mechanism at each position of the accommodated state and the extended state so as not to move easily by touching.

  A protruding auxiliary stopper 161 is formed on the rear end side (the right end side in FIG. 6A) of the connection portion 160.

  Thus, as shown in FIG. 6B, the distal end of the movable unit 152 is held in the extended state while being inclined to the right end in FIG. 6B.

  Therefore, when the nozzle main body 150 is inserted between the objects to be dried such as a futon (when inserted), the extended state of the movable unit 152 can be maintained.

  In the above-described configuration example, as shown in FIG. 5 and the like, the rotation shaft 155 is disposed in the left-right direction (X direction) intersecting the up-down direction (Y direction), but is not limited thereto. With a configuration in which the shaft is provided to intersect the vertical direction (Y direction), the same effect that the object to be dried is lifted and the arrival space of the heated air can be expanded.

  With such a configuration, the nozzle body 150 can lift an object to be dried such as a futon on the distal end side of the movable unit 152 in the extended state in which the movable unit 152 is extended above the nozzle unit 151, and It is possible to expand (increase) the arrival space of the air.

  Here, an example of a use state of the drying device according to the present embodiment will be described with reference to FIG.

  In the example of use shown in FIG. 7, the hose 5 and the nozzle body 150 constituting a part of the discharging means are laid on a futon 801 as another object to be dried on a futon 800 as an object to be dried. It is inserted between the comforter 800 and the comforter 801 so as to be covered by the comforter 801. At this time, the movable unit 152 constituting the space expansion mechanism is rotated with respect to the nozzle unit 151 to be in an extended state.

  Thereby, the comforter 801 as a material to be dried can be lifted to expand the reaching space 850 of the heated air.

  When hot air is supplied through the hose 5 in such a state, hot air is blown from the front outlet 170 and the auxiliary outlet 180 of the nozzle unit 151.

  Then, as indicated by the arrow shown in FIG. 7, the warm air wraps around the upper part in the space 850 and spreads widely, and can more efficiently dry the comforter 801 and the mattress 800 as objects to be dried.

  Therefore, even a relatively large object to be dried, such as a double-size futon, can be dried more efficiently.

  As shown in FIGS. 5 (b) and 6 (b), the corners 152d, 152e above the side plates 152b, 152c of the movable unit 152 have a rounded shape. It is possible to prevent the object from being caught on the object to be dried.

  Further, since the semicircular finger hooks 156 are formed at the edges of the side plates 152b and 152c of the movable unit 152, the movable unit 152 can be easily shifted from the housed state to the extended state. .

  Furthermore, in the housed state where the movable unit 152 is held along the nozzle unit 151, the auxiliary outlets 180 formed on both side surfaces of the nozzle unit 151 are closed by the side plate portions 152b and 152c of the movable unit 152. Dust can be prevented from entering the nozzle unit 151 from the auxiliary outlet 180. In addition, when the drying apparatus 1 is not used, the hose 5 is stored in a bent state as shown in FIG. 1 and the like, so that the front outlet 170 is closed to face the upper surface of the housing 3, so that the front outlet 170 is closed. Intrusion of garbage from 3 can also be prevented. Therefore, it is possible to keep the inside of the nozzle unit 151 clean in the housed state.

  In the examples shown in FIGS. 5 and 6, the side plate portions 152 b and 152 c cover most of the side surfaces of the nozzle unit 151 in which the auxiliary outlets 180 are formed. However, the present invention is not limited thereto. What is necessary is just to be the structure which covers at least the auxiliary outlet 180.

  Also, the upper plate 152a only needs to cover at least a part thereof.

  Further, in the present embodiment, the configuration in which the movable unit 152 forming a part of the space expansion mechanism is rotated has been described. However, the present invention is not limited to this. As a configuration or the like, the position of the movable unit 152 may be changed.

  Further, the movable unit 152 itself may rotate in the left-right direction (X direction) in FIG.

  Further, a plurality of movable units 152 constituting a part of the space expansion mechanism may be provided in the nozzle unit 151.

  Instead of the space expansion mechanism as described above, the space 850 in the object to be dried may be expanded by the air pressure of the heated air blown out from the air outlet formed on the upper surface of the nozzle unit 151 or the like. That is, for example, a balloon may be provided at an air outlet formed on the upper surface or the like, and the space 850 in the object to be dried may be expanded by expanding the balloon.

  Further, the movable unit 152 may be configured to be swingable by the power of a motor or the like, and the space 850 in the object to be dried may be intermittently expanded. That is, for example, a swing mechanism that swings the movable unit 152 intermittently by a predetermined control device can be provided above the nozzle unit 151.

(Configuration of heating means)
With reference to FIG. 8 and FIG. 9, a description will be given of a heating unit included in the drying device 1 according to the present embodiment.

  Here, FIG. 8 is an AA sectional view of FIG. 4 showing an internal configuration of the drying apparatus 1 according to the embodiment, and FIG. 9 shows an internal configuration of a heater case 400 constituting a main part of the drying apparatus 1. FIG. 9 is a sectional view taken along line BB of FIG. 8.

  In the drying device 1 according to the present embodiment, the heating means includes a heater H having a substantially rectangular shape, and a heater case 400 for supporting the heater H in the housing 3.

  The heater H is composed of, for example, a PTC (Positive Temperature Coefficient) heater or the like. As shown in FIG. 9, the heater H is provided with three power supply cables 501.

  Further, the heater case 400 is formed in a tubular shape with a heat-resistant resin or the like.

  In the heater case 400, thermistors S1 and S2 as temperature detecting units are provided at a plurality of (two in the configuration examples shown in FIGS. 8 and 9) spaced apart.

  More specifically, the thermistor S1 is provided substantially above the center in the width direction of one side of the heater H in a state where the drying device 1 is upright as shown in FIG. The connection cord 402 extends from both ends of the thermistor S1 and is connected to the above-described control board or the like. Further, the thermistor S1 itself is locked by a hook 401 formed in the heater case 400.

  On the other hand, the thermistor S2 is provided above the corner of the one side of the heater H in a state where the drying device 1 is upright as shown in FIG.

  A connection cord 404 extends from both ends of the thermistor S2 and is connected to the above-described control board or the like. Further, the thermistor S2 itself is locked by a hook 403 formed in the heater case 400.

  In the thermistors S1 and S2, the position of the temperature detector (the substantially central portion of a straight tube) of the thermistor S2 is higher than the position of the temperature detector (the substantially central portion of a straight tube bent in a U shape) of the thermistor S1. Are also arranged close to the surface of the heater H. Since the thermistor S1 is arranged in a direction orthogonal to the flow of the hot air at the position where the hot air passing through the heater H is received, the temperature of the hot air can be detected efficiently.

  On the other hand, since the thermistor S2 is disposed in the direction orthogonal to the surface of the heater H near the corner of the heater H, it can receive the radiant heat generated from the heater H and efficiently detect the temperature of the heater H. .

  With such a configuration, the temperature of the heater H can be more accurately detected even when the drying device 1 is in various postures during use.

  That is, as shown in FIGS. 3 and 4, when the drying device 1 is used in a posture in which the operation panel 35 is on the upper side, when the air for drying the object to be dried such as the futon is mainly blown by the thermistor S1. Perform temperature detection.

  On the other hand, when the air supply is stopped, the temperature is mainly detected by the thermistor S2. Thus, when the air supply is stopped, more accurate temperature detection can be performed by the thermistor S2 disposed closer to the heater H, and safety can be improved.

  In addition, the stop of the air blowing here means not only the case where the operator intentionally stops the air blowing by operating the operation panel 35 (see FIG. 1), but also the control at the time of detecting the abnormality or the operation of the operator due to mechanical damage or the like. Includes unintentional shutdowns.

  Further, as shown in FIG. 8 and the like, when the drying apparatus 1 is used in an upright posture, the temperature is mainly detected by the thermistor S1 at the time of blowing air for drying an object to be dried such as shoes.

  On the other hand, when the air supply is stopped, the temperature is detected by the thermistors S1 and S2. Thereby, more accurate temperature detection can be performed when the air supply is stopped, and safety can be improved.

  Further, when the drying apparatus 1 is used in the sideways position, the temperature is mainly detected by the thermistor S1 when blowing air to dry the object to be dried such as a futon.

  On the other hand, when the air supply is stopped, the temperature is detected by the thermistor S2. Thus, when the air supply is stopped, more accurate temperature detection can be performed by the thermistor S2 located above the heater H, and safety can be improved.
