The defined surface is defined as the bottom surface.

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

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

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

As shown in FIG. 2, in the housing 3, a sirocco fan 300 (see FIG. 7, which will be described later) that discharges the air sucked from the intake ports 200a to 200c from the discharge part 51, the sirocco fan 300 and the discharge part 51. A heater H, which constitutes a heating means, and a motor M as a driving source of the sirocco fan 300 are housed between the and.

In addition, in the housing 3, there is provided an air blowing unit 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 part 51 is a cylindrical body connected to the upper part of the housing 3, and is configured to discharge the air obtained from the blowing means to the outside.

One end of the hose 5 is connected to the discharge part 51. The hose 5 has a flexible bellows-like structure, and is housed 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 D2 direction as shown in FIG.

Instead of the flexible hose 5 as described above, a solid pipe-shaped member made of inflexible metal or resin may be used.

At the other end of the hose 5, a nozzle body 150 that blows out the air sent from the discharge part 51 is provided. When the drying device 1 is not used, the nozzle body 150 is attached and stored in a part of the housing 3 as shown in FIG. 1 and the like, and is used in a state where the nozzle body 150 is removed from the housing 3 when using the futon drying or the like.

The nozzle body 150 is not limited to the structure connected to the end of the hose 5, but may be directly connected to the housing 3 or may be connected to the tip of the solid pipe as described above. Good.

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

In addition, the nozzle body 150 is provided with a space expansion mechanism that lifts the article to be dried and expands the reaching space of the heated air in a state where the nozzle body is covered with the article to be dried such as a futon. There is.

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

Here, in the drying execution state of the material to be dried by the drying device 1, the air heated through the nozzle body 150 is sequentially fed, and gradually escapes from the gap of the material to be dried such as a futon to the outside with the passage of time. I will go. The “arrival space” referred to in the present embodiment means a space in which the air thus sent through the nozzle body 150 temporarily stays until it escapes to the outside. That is, the “arrival space” can be said to be a substantially closed space formed around the nozzle body 150 by the object to be dried when the discharging means 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 surface side of the housing 3. In addition, 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.

Then, in the housing 3, a heater H as a heating means is arranged at a position P corresponding to between the first protrusion 130 and the second protrusion 131. The first protrusion 130 and the second protrusion 131 are configured so that the protrusion amounts toward the back surface are the same.

With such a configuration, when the drying device 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 are used. A space is formed at a corresponding position P between 131. Since heat is dissipated through the housing 3 by this space, it is possible to suppress the excessive temperature rise of the heater H. A heat insulating material (for example, a heat insulating sheet made of an 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)), heat transfer to the housing 3 can be suppressed.

In addition, as shown in FIGS. 1, 3 and 4, the drying device 1 according to the present embodiment includes a bottom inlet port 200 a formed on the bottom surface of the housing body 30, and the left and right sides of the housing body 30. It has two side inlets 200b, 200c formed on the side.

Thereby, the 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 intake ports 200a to 200c are provided in three directions of the drying device 1, the upright state as shown in FIG. 1A and the operation panel 35 as shown in FIGS. 3 and 4 are directed upward. In addition to the state (so-called futon dry state), sufficient inhalation can be performed when using the three modes of the state in which the side air inlet 200c is placed upward (so-called sideways state).

It should be noted that a usage state in which the side air 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 addition, in order to prevent such a use state, a tilt sensor (tilt switch) is provided on a control board (not shown) or the like, and when a tilt such that the side air intake port 200b is located above is detected, , A safety mechanism for turning off the power of the heater H and the like is incorporated.

(Structure of nozzle body and space expansion mechanism)
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 with reference to FIGS. 5 and 6.

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

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

The nozzle body 150 is composed of a nozzle unit 151 arranged on the tip 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 of the nozzle unit 151 (the left end of FIGS. 6A and 6B). It should be noted that the front outlet 170 can be attached with an attachment used for drying shoes, or an optional item such as an aroma case for giving out an aroma.

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 the material to be dried such as the futon can be improved. The auxiliary outlet may be provided on the upper surface of the nozzle unit 151.

At the rear end portion of the nozzle unit 151 (right end portion in FIGS. 6A and 6B), a connecting portion 160 rotatably connected to the hose 5 is provided. That is, the rear end of the nozzle unit 151 is parallel to the air flow 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 (Z direction in FIGS. 6A and 6B). It is connected so that it can freely rotate about its own axis. As a result, the nozzle body 150 can be installed in the most suitable direction for drying an object to be dried such as a futon, and the hose 5 can be prevented from twisting depending on the direction of the nozzle body 150.

The movable unit 152, which constitutes the space expansion mechanism, is provided so that its posture can be changed with respect to the nozzle unit 151.

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

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

In the configuration example shown in FIGS. 5 and 6, the movable unit 152 has a rotating shaft 155 arranged in a direction intersecting with the ventilation direction of the nozzle unit 151, so that the movable unit 152 is moved in the direction of the arrow D1 with respect to the nozzle unit 151 (see FIG. ) And FIG. 6( b )) are pivotally supported.

Further, 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 covers both side surface portions of the nozzle unit 151 in the housed state.

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

More specifically, a protrusion-shaped rotating shaft 155 is integrally formed inside the side plate portions 152b and 152c (see FIG. 5B), and the engagement formed on the side wall of the nozzle unit 151 is performed. A tip portion of the 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 housed state (states of FIGS. 5A and 6A) and extend the movable unit 152 (see FIG. 5B). ) And the state shown in FIG. 6B) are provided.

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

FIG. 10A is a partial perspective view of the nozzle unit 151 showing a configuration example of the stopper structure included 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 stoppers are formed on the peripheral edge of the bearing portion 157 of the rotary shaft located on the rear end side of the nozzle unit 151 in the drawing.

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

When the movable unit 152 is accommodated, the protrusion 902 on the movable unit 152 side is locked by the protrusion 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 way, the stopper mechanism holds the movable unit 152 in each of the housed state and the extended state so that the movable unit 152 does not easily move when touched.

Further, a protrusion-shaped 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. 6B, the tip of the movable unit 152 is held in the extended state while being inclined to the right end side in FIG. 6B.

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

In addition, in the above configuration example, as shown in FIG. 5 and the like, the rotation shaft 155 is arranged in the left-right direction (X direction) intersecting the up-down direction (Y direction), but the invention is not limited to this. With the configuration in which the axis intersects with the vertical direction (Y direction), the same effect of lifting the object to be dried and expanding the reaching space of the heated air can be obtained.

With such a configuration, the nozzle body 150 can lift an object to be dried such as a futon at the tip side of the movable unit 152 and heat it when the movable unit 152 is extended above the nozzle unit 151. It is possible to expand (increase) the reaching space of air.

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

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

As a result, the comforter 801 serving as the object to be dried can be lifted to expand the reaching space 850 for the heated air.

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

Then, as shown by the arrow shown in FIG. 7, the warm air circulates to 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, for example, even a relatively large object to be dried such as a double-sized futon can be more efficiently dried.

As shown in FIGS. 5(b) and 6(b), since the upper corner portions 152d and 152e of the side plate portions 152b and 152c of the movable unit 152 have a rounded shape, a futon or the like is used. It is possible to prevent the material to be dried from being caught.

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

Further, 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 plate portions 152b and 152c of the movable unit 152. It is possible to prevent dust from entering the nozzle unit 151 through the auxiliary outlet 180. In addition, when the drying device 1 is not used, the front outlet 170 is closed by facing the upper surface of the housing 3 by storing the hose 5 in a bent state as shown in FIG. It is also possible to prevent dust from entering from 3. Therefore, it is possible to keep the inside of the nozzle unit 151 clean in the housed state.

In the example shown in FIGS. 5 and 6, the side plate portions 152b, 152c cover most of the side surface of the nozzle unit 151 in which the auxiliary outlet 180 is formed, but the present invention is not limited to this. It is sufficient that at least the auxiliary outlet 180 is covered.

Further, the upper plate portion 152a may cover at least a part.

Further, in the present embodiment, the configuration in which the movable unit 152 that constitutes a part of the space expansion mechanism is rotated has been described, but the present invention is not limited to this, and it is expandable and contractible by sliding in the vertical direction (Y direction). 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, the nozzle unit 151 may be provided with a plurality of movable units 152 that form 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 the heated air blown from the air blowout port formed on the upper surface of the nozzle unit 151 or the like. That is, for example, a balloon may be provided in the air outlet formed on the upper surface or the like, and the space 850 in the object to be dried may be expanded by the expansion of 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 material 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.

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

Here, FIG. 8 is a cross-sectional view taken along the line AA of FIG. 4 showing an internal configuration of the drying device 1 according to the embodiment, and FIG. 9 shows an internal configuration of a heater case 400 that constitutes a main part of the drying device 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 that supports 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 from a heat resistant resin or the like.

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

More specifically, the thermistor S1 is provided substantially above the center of one side of the heater H in the width direction when the drying device 1 is upright as shown in FIG. A connection cord 402 extends from both ends of the thermistor S1 and is connected to the above-mentioned 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 one side of the heater H when the drying device 1 is upright as shown in FIG.

Further, the connection cords 404 are extended from both ends of the thermistor S2 and are connected to the above-mentioned control board or the like. The thermistor S2 itself is locked by a hook 403 formed in the heater case 400.

In addition, in the thermistors S1 and S2, the position of the temperature detecting portion of the thermistor S2 (the substantially central portion of the straight tube) is closer to that of the temperature detecting portion of the thermistor S1 (the substantially central portion of the straight tube bent in a U-shape). 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 warm air at the position where the hot air that has passed through the heater H is received, the temperature of the warm air can be detected efficiently.

On the other hand, since the thermistor S2 is arranged near the corner of the heater H in a direction orthogonal to the surface of the heater H, the thermistor S2 can receive the radiant heat emitted 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 detected more accurately even when the drying device 1 is in various postures during use.

That is, as shown in FIG. 3 and FIG. 4, when the drying device 1 is used with the operation panel 35 facing upwards, the thermistor S1 is mainly used when blowing air to dry an object to be dried such as a futon. Detects temperature.

On the other hand, when the air blow is stopped, the temperature is mainly detected by the thermistor S2. As a result, when the air blow is stopped, the thermistor S2 arranged closer to the heater H can detect the temperature more accurately, and the safety can be improved.

It should be noted that the term “stop blowing air” here means not only the case where the operator intentionally stops blowing air by operating the operation panel 35 (see FIG. 1 ), but also the operation of the operator due to control at the time of abnormality detection or mechanical damage. Including unintentional stoppage.

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

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

Further, when the drying device 1 is used in the laid-down posture, the temperature is mainly detected by the thermistor S1 when air is blown to dry an object to be dried such as a futon.

On the other hand, when the ventilation is stopped, the thermistor S2 detects the temperature. Accordingly, when the air blow is stopped, the thermistor S2 located above the heater H can detect the temperature more accurately, and the safety can be improved.
