As shown in FIGS. 1 and 2, the drying apparatus 1 includes a substantially rectangular parallelepiped housing 3 having intake ports 200a to 200c, a discharge portion 51, and the like.

The housing 3 is composed of a housing body 30 and a lid member 31 . Although the detailed configuration is omitted, an operation panel 35 is arranged on the surface side of the lid member 31 . A control board (not shown) is arranged on the rear surface side of the lid member 31 .

A handle 36 used for carrying the drying apparatus 1 is formed on the top of the housing body 30 and the lid member 31 when the housing 3 is in an upright state (see FIG. 1(a)).

As shown in FIG. 2, the housing 3 contains a sirocco fan 300 (see FIG. 7 described later) that discharges the air sucked from the intake ports 200a to 200c from the discharge portion 51, the sirocco fan 300 and the discharge portion 51. A heater H constituting a heating means installed between and a motor M as a driving source of the sirocco fan 300, etc. are accommodated.

In addition, a sirocco fan 300 and an air blowing means composed of a scroll-shaped casing C covering the sirocco fan 300 are provided in the housing 3 (see FIG. 8 described later).

The discharge part 51 is a cylindrical body connected to the upper part of the housing 3, and is configured to discharge the air generated by the air blowing means to the outside.

One end of the hose 5 is connected to the discharge portion 51 . The hose 5 has a flexible bellows-like structure, and is stored in a bent state as shown in FIG. 1 and the like when the drying apparatus 1 is not used. Also, the hose 5 is used in a state of being raised and extended in the D2 direction as shown in FIG. 1(a).

Instead of the hose 5 having flexibility as described above, a solid pipe-shaped one made of metal or resin having no flexibility may be used.

The other end of the hose 5 is provided with a nozzle body 150 for blowing out the air supplied from the discharge portion 51 . The nozzle body 150 is attached and housed in a part of the housing 3 as shown in FIG. 1 and the like when the drying device 1 is not in use, and is removed from the housing 3 during use such as drying a futon.

Note that the nozzle body 150 is not limited to the configuration in which it is 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 or the like as described above. good too.

The discharge part 51, the hose 5, and the nozzle body 150 described above constitute discharge means for discharging heated air while being covered with the material to be dried by inserting it between the materials to be dried such as a blanket. ing.

When drying the bedding, it is sufficient that at least the nozzle body 150 is covered with the material to be dried such as the bedding, and it is not necessary to insert the discharge part 51 and the hose 5 into the bedding.

Further, the nozzle body 150 is provided with a space expansion mechanism that expands the reachable space of the heated air by lifting the object to be dried in a state where the nozzle body is covered with the object to be dried such as a futon. there is

The space expansion mechanism is composed of, for example, a movable unit 152 provided in the nozzle body 150, which will be described later.

Here, in the drying execution state of the material to be dried by the drying device 1, the heated air is sequentially sent through the nozzle body 150, and gradually escapes to the outside through the gaps of the material to be dried such as the futon as time elapses. I will go. The “reaching space” referred to in the present embodiment refers to a space in which the air that has been sent through the nozzle body 150 in this way temporarily stays until it escapes to the outside. That is, the "reaching space" can be said to be a substantially closed space formed around the nozzle main body 150 by the material to be dried when the discharge means is inserted into the material to be dried.

As shown in FIGS. 1(b), 3 and 4, a first protrusion 130 formed along the outer periphery of the casing C is provided on the rear side of the housing 3. As shown in FIG. 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.

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

With such a configuration, when the drying apparatus 1 is used with the back side of the housing 3 placed on a floor surface or an object to be dried such as a futon, the first protrusion 130 and the second protrusion A space is formed at the corresponding position P between 131 . Due to this space, heat is dissipated through the housing 3, so that the heater H can be prevented from overheating. Between the heater case 400 covering the heater H and the housing 3, a heat insulating material (for example, a heat insulating sheet made of aluminum tape containing glass fiber, etc.) 401 is interposed (see FIG. 3 and described later). 8), heat transfer to the housing 3 can be suppressed.

1, 3, and 4, the drying device 1 according to the present embodiment has a bottom air intake port 200a formed in the bottom surface of the housing body 30, as well as left and right air intakes of the housing body 30. It has two side inlets 200b, 200c formed on the side.

As a result, the air intake efficiency can be enhanced, the amount of air discharged from the nozzle body 150 can be increased, and the drying efficiency can be improved.

In addition, since the air inlets 200a to 200c are provided in three directions of the drying apparatus 1, the drying apparatus 1 can be placed in an upright state as shown in FIG. In addition to the state (so-called futon dry state), it is possible to perform sufficient air intake in three modes of use, namely, the state in which the side air intake port 200c is placed upward (so-called sideways state).

A use condition in which the side intake port 200b faces upward is not assumed. This is because it becomes difficult to send sufficient air around the motor M to cool it.

Further, in order to prevent such a use state, a tilt sensor (tilt switch) is provided on the control board (not shown) or the like, and when it detects a tilt such that the side intake port 200b faces upward, , a safety mechanism for turning off the heater H, etc. is incorporated.

(Configuration of Nozzle Body and Spatial Expansion Mechanism)
5 and 6, the configuration and operation of the nozzle unit 151 and the movable unit 152 that constitute the configuration of the nozzle body 150 and the space expansion mechanism will be described.

FIG. 5(a) is a perspective view showing the closed state of the movable unit 152 that constitutes the main part of the nozzle body 150 of the drying device 1 according to the embodiment, and FIG. 5(b) shows the open state of the movable unit 152. It is a perspective view showing.

6(a) is a side view showing a closed state of the movable unit 152 of the drying apparatus 1, and FIG. 6(b) is a side view showing an open state of the movable unit 152. FIG.

The nozzle body 150 is composed of a nozzle unit 151 arranged on the tip side of the hose 5 and a movable unit 152 provided in the nozzle unit 151 .

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

A plurality of slit-shaped auxiliary outlets 180 are provided on the left and right side surfaces of the nozzle unit 151 . Thus, in addition to the air flow from the front air outlet 170, the air flow can also be discharged from the auxiliary air outlet 180, thereby improving the drying efficiency of the material to be dried such as the bedding. In addition, the auxiliary outlet may be provided on the upper surface of the nozzle unit 151 .

A connection portion 160 that is rotatably connected to the hose 5 is provided at the rear end portion (the right end portion in FIGS. 6A and 6B) of the nozzle unit 151 . That is, the rear end of the nozzle unit 151 is parallel to the airflow direction 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). are rotatably connected about an axis. As a result, the nozzle body 150 can be installed in the optimum direction for drying the material to be dried, such as a blanket, and the twisting of the hose 5 due to the direction of the nozzle body 150 can be avoided.

A movable unit 152 constituting a 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 nozzle unit 151 in an extended state (see FIGS. 5(b) and 6(b)) extended in a direction orthogonal to the ventilation direction. It is constructed so as to be selectively changeable between the housed state (see FIGS. 5(a) and 6(a)).

Note that the extending direction of the movable unit 152 is not limited to the direction perpendicular to the ventilation direction, and may be any direction that intersects the ventilation direction.

In the configuration examples shown in FIGS. 5 and 6, the movable unit 152 is rotated with respect to the nozzle unit 151 in the direction of arrow D1 (FIG. ) and FIG. 6(b)).

The movable unit 152 also includes an upper plate portion 152a that covers at least a portion 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 in the accommodated state.

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

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

Further, the nozzle unit 151 and the movable unit 152 hold the movable unit 152 in the accommodated state (states shown in FIGS. 5A and 6A), and extend the movable unit 152 (FIG. 5B). ) and FIG. 6(b)) are provided.

Here, a configuration example of the stopper mechanism will be described with reference to FIG. 10 .

FIG. 10(a) 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. 10(b) is a perspective view of the rear side of the movable unit 152. FIG.

As shown in FIG. 10A, two protrusions 901a and 901b for stoppers are formed on the peripheral edge of the bearing portion 157 of the rotating shaft positioned 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 rotating shaft 155 of the movable unit 152 that is rotatably engaged with the nozzle unit 151 is locked by projections 901a and 901b on the nozzle unit 151 side. A possible protrusion 902 is integrally formed.

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

In this manner, the stopper mechanism holds the movable unit 152 between the housed state and the extended state so that it does not move easily even if it is touched.

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

As a result, as shown in FIG. 6(b), the distal end of the movable unit 152 is held in an extended state in a state inclined to the right end side in FIG. 6(b).

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

In the above configuration example, as shown in FIG. 5 and the like, the rotation shaft 155 is arranged in the horizontal direction (X direction) intersecting the vertical direction (Y direction). With a configuration in which the shaft intersects the vertical direction (Y direction), a similar effect can be obtained in that the object to be dried is lifted and the heated air reaches a larger space.

With such a configuration, the nozzle body 150 can lift an object to be dried such as a bedding at the tip side of the movable unit 152 in the extended state in which the movable unit 152 is extended above the nozzle unit 151, thereby heating the object to be dried. It is possible to extend (increase) the reachable space of the air.

Now, with reference to FIG. 7, an example of the usage state of the drying device according to the present embodiment will be described.

In the example of use shown in FIG. 7, a quilt 800 as an object to be dried is covered with a quilt 801 as another object to be dried. It is inserted between 800 and comforter 801 so that it is covered by comforter 801 . At this time, the movable unit 152 constituting the space expansion mechanism is rotated with respect to the nozzle unit 151 so as to be in an extended state.

As a result, the comforter 801 as the 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 this state, the hot air is blown out from the front outlet 170 and the auxiliary outlet 180 of the nozzle unit 151 .

7, the warm air reaches the upper part of the space 850 and spreads widely, so that the comforter 801 and the mattress 800 as the objects to be dried can be dried more efficiently.

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

5(b) and 6(b), the upper corners 152d and 152e of the side plate portions 152b and 152c of the movable unit 152 are rounded. It is possible to suppress catching on the material to be dried.

In addition, since 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 moved from the accommodated state to the extended state. .

Furthermore, in the accommodated state in which 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 plates 152b and 152c of the movable unit 152. Intrusion of dust into the nozzle unit 151 from the auxiliary outlet 180 can be prevented. In addition, when the drying apparatus 1 is not used, the hose 5 is stored in a bent state as shown in FIG. Intrusion of dust from 3 can also be prevented. Therefore, it is possible to keep the inside of the nozzle unit 151 clean in the stored state.

In the examples shown in FIGS. 5 and 6, the side plate portions 152b and 152c cover most of the side surface of the nozzle unit 151 in which the auxiliary outlet 180 is formed. It suffices if it is configured to cover at least the auxiliary outlet 180 .

At least a part of the upper plate portion 152a may also be covered.

Further, in the present embodiment, the configuration for rotating the movable unit 152 that constitutes a part of the space expansion mechanism has been described, but the present invention is not limited to this, and the movable unit 152 can extend and contract such as sliding in the vertical direction (Y direction). As a configuration or the like, the position of the movable unit 152 may be changed.

Also, the movable unit 152 itself may rotate in the horizontal direction (X direction) in FIG.

Furthermore, the nozzle unit 151 may be provided with a plurality of movable units 152 that constitute a part of the space expansion mechanism.

Instead of the space expansion mechanism as described above, the space 850 in the material to be dried may be expanded by the air pressure of heated air blown out from an 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 inside the material to be dried may be expanded by expanding the balloon.

Further, the movable unit 152 may be configured to be swingable by power such as a motor, and the space 850 inside the material to be dried may be expanded intermittently. That is, for example, above the nozzle unit 151, a swinging mechanism for intermittently swinging the movable unit 152 by means of a predetermined control device can be provided.

(Structure of heating means)
The heating means provided in the drying apparatus 1 according to the present embodiment will be described with reference to FIGS. 8 and 9. FIG.

Here, FIG. 8 is a cross-sectional view taken along line AA of FIG. 4 showing the internal configuration of the drying apparatus 1 according to the embodiment, and FIG. FIG. 9 is a cross-sectional view taken along the line BB of FIG. 8;

In the drying apparatus 1 according to the present embodiment, the heating means is composed of a substantially rectangular heater H and a heater case 400 that supports the heater H within the housing 3 .

The heater H is composed of, for example, a PTC (Positive Temperature Coefficient) heater or the like. In addition, 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 from a heat-resistant resin or the like.

In the heater case 400, thermistors S1 and S2 as temperature detection units are provided at a plurality of (two locations in the configuration examples shown in FIGS. 8 and 9) separated from each other.

More specifically, the thermistor S1 is provided substantially above the center in the width direction of one side of the heater H in the upright state of the drying apparatus 1 as shown in FIG. A 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 inside the heater case 400 .

On the other hand, the thermistor S2 is provided above the corner of the one side of the heater H when the drying apparatus 1 is erected 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 inside the heater case 400. As shown in FIG.

In the thermistors S1 and S2, the position of the temperature detection portion of the thermistor S2 (substantially central portion of the straight pipe) is closer to the position of the temperature detection portion of the thermistor S1 (substantially the central portion of the straight pipe bent into a U-shape). are arranged so as to be close to the surface of the heater H. Since the thermistor S1 is arranged in a direction perpendicular to the flow of hot air at a position where it receives the hot air that has passed through the heater H, it can efficiently detect the temperature of the hot air.

On the other hand, since the thermistor S2 is arranged in the vicinity of the corner of the heater H in a direction orthogonal to the surface of the heater H, it receives the radiant heat emitted from the heater H and can efficiently detect the temperature of the heater H. .

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

That is, as shown in FIGS. 3 and 4, when the drying apparatus 1 is used with the operation panel 35 facing upward, the thermistor S1 is mainly used when blowing air to dry an object to be dried such as a futon. Perform temperature detection.

On the other hand, when air blowing is stopped, the temperature is mainly detected by the thermistor S2. As a result, the thermistor S2, which is located closer to the heater H, can perform more accurate temperature detection when air blowing is stopped, and safety can be improved.

In addition, the blowing stop here refers to the case where the operator intentionally stops the blowing by operating the operation panel 35 (see FIG. 1), as well as the case where the operator stops the blowing due to the control at the time of abnormality detection or mechanical damage. Including unintended stops.

Further, as shown in FIG. 8 and the like, when the drying apparatus 1 is used in an upright position, the temperature is mainly detected by the thermistor S1 when blowing air to dry the articles to be dried such as shoes.

On the other hand, when air blowing is stopped, temperature detection is performed by thermistors S1 and S2. As a result, more accurate temperature detection can be performed when air blowing is stopped, and safety can be improved.

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

On the other hand, when the blowing is stopped, the temperature is detected by the thermistor S2. As a result, the thermistor S2 positioned above the heater H can detect the temperature more accurately when the blowing of air is stopped, and the safety can be improved.
