Further, in the drying device 1, the surface provided with the operation panel 35 and the like described later is the front surface, the surface provided with the first protrusion 130 and the like described later is the back surface, and the intake port 200c described later (see FIG. 2). The surface on which the above is provided is the right side surface, the surface on which the intake port 200b (see FIG. 1B) and the like described later is provided is the left side surface, and the surface on which the intake port 200a and the like are provided will be provided on the left side surface, and the intake port 200a (see FIG. 1B) described later is provided. The 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 and 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, the operation panel 35 is arranged on the surface side of the lid member 31. Further, 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 for carrying the drying device 1 is formed on the upper part of the housing body 30 and the lid member 31.

As shown in FIG. 2, the sirocco fan 300 (see FIG. 7 described later) that discharges the air sucked from the intake ports 200a to 200c from the discharge unit 51, and the sirocco fan 300 and the discharge unit 51 are inside the housing 3. A heater H constituting a heating means installed between the two, a motor M as a drive source for the sirocco fan 300, and the like are housed.

A sirocco fan 300 and a blowing means composed of a scroll-shaped casing C covering the sirocco fan 300 are provided in the housing 3 (see FIG. 8 below).

Further, the discharge unit 51 is a tubular body connected to the upper part of the housing 3, and is configured to discharge the wind obtained from the blower 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 device 1 is not in use. Further, 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 flexible hose 5 as described above, a solid pipe-shaped hose formed of a metal or resin having no flexibility may be used.

At the other end of the hose 5, a nozzle body 150 for blowing out air supplied from the discharge portion 51 is provided. As shown in FIG. 1 and the like, the nozzle body 150 is worn and stored in a part of the housing 3 when the drying device 1 is not used, and is used in a state of being removed from the housing 3 when the futon dryer or the like is used.

The nozzle body 150 is not limited to the configuration 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 a solid pipe or the like as described above. May be good.

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

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

Further, the nozzle body 150 is provided with a space expansion mechanism that lifts the object to be dried and expands the reachable space of the heated air while the nozzle body is covered with an object to be dried such as a futon. There is.

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

Here, in the drying execution state of the object 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 gap of the object to be dried such as a futon with the passage of time. I will go. The "reach space" referred to in the present embodiment means a space in which the air sent through the nozzle body 150 in this way temporarily stays until it escapes to the outside. That is, the "reach 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 means is inserted into the object to be dried.

As shown in FIGS. 1B, 3 and 4, a first protrusion 130 formed along the outer circumference of the casing C is provided on the back surface 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.

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

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

Further, as shown in FIGS. 1, 3 and 4, in the drying device 1 according to the present embodiment, in addition to the bottom air intake port 200a formed on the bottom surface of the housing body 30, the left and right sides of the housing body 30 are provided. It is provided with two side intake ports 200b and 200c formed on the side surface.

As a result, 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 the 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 dry futon state), sufficient air intake can be performed in the three modes of use in the state in which the side intake port 200c is placed so as to be upward (so-called sideways state).

It should 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.

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

(Nozzle body and space expansion mechanism configuration)
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 with reference to FIGS. 5 and 6.

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

FIG. 6A is a side view showing the closed state of the movable unit 152 of the drying device 1, and FIG. 6B is a side view showing the open 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 on the nozzle unit 151.

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

Further, a plurality of slit-shaped auxiliary outlets 180 are provided on the left and right side surfaces of the nozzle unit 151. As a result, in addition to the air flow from the front outlet 170, the air flow can be discharged from the auxiliary outlet 180, and the drying efficiency of the object 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.

A connecting portion 160 that is rotatably connected to the hose 5 is provided at the rear end portion (the right end portion on FIGS. 6A and 6B) of the nozzle unit 151. That is, the rear end portion of the nozzle unit 151 is parallel to the ventilation 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 rotatably connected around a vertical axis. As a result, the nozzle body 150 can be installed in the direction optimal for drying with respect to the object to be dried such as a futon, and the situation where the hose 5 is twisted depending on the direction of the nozzle body 150 can be avoided.

The movable unit 152 constituting the space expansion mechanism is provided so that the posture of the movable unit 152 can be changed with respect to the nozzle unit 151.

More specifically, the movable unit 152 is held in an extended state (see FIGS. 5 (b) and 6 (b)) extended in a direction orthogonal to the ventilation direction and along the nozzle unit 151. It is configured to be selectively changeable to the containment state (see FIGS. 5 (a) and 6 (a)).

The extending direction of the movable unit 152 is not limited to the direction orthogonal to the ventilation direction, and may be a direction intersecting the ventilation direction.

In the configuration examples shown in FIGS. 5 and 6, the movable unit 152 has a rotation shaft 155 arranged in a direction intersecting the ventilation direction of the nozzle unit 151 in the arrow D1 direction with respect to the nozzle unit 151 (FIG. 5 (b). ) And FIG. 6B) are rotatably 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 in the accommodated state, and side plate portions 152b and 152c that cover both side surface portions 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 the rotating shaft 155.

More specifically, the protruding 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. The tip of the rotating shaft 155 is rotatably engaged with the 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 (FIG. 5 (b)). ) And the state of FIG. 6 (b)) are provided with a stopper mechanism.

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

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 surface 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 rotating 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 surfaces of the rotation shaft 155 of the movable unit 152 rotatably engaged with the nozzle unit 151 are locked by the protrusions 901a and 901b on the nozzle unit 151 side. Possible protrusions 902 are integrally formed.

Then, in the housed state of the movable unit 152, 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 movable unit 152 is held by the stopper mechanism at each position in the housed state and the extended state so as not to move easily by touching.

Further, a protrusion-shaped auxiliary stopper 161 is formed on the rear end side (right end side on FIG. 6A) of the connection portion 160.

As a result, as shown in FIG. 6 (b), the tip end portion of the movable unit 152 is held in the extended state in a state of being tilted toward the right end portion on FIG. 6 (b).

Therefore, when the nozzle body 150 is inserted (inserted) between objects to be dried such as a futon, 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 left-right direction (X direction) intersecting the vertical direction (Y direction), but the rotation is not limited to this. If the shafts are provided so as to intersect the vertical direction (Y direction), the same effect of lifting the object to be dried and expanding the reach 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 on 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, and heats the nozzle body 150. It is possible to expand (increase) the arrival space of air.

Here, an example of a usage state of the drying apparatus 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 that form a part of the discharge means are laid on the mattress 800 as the object to be dried while the comforter 801 as another object to be dried is hung. It is inserted between the 800 and the comforter 801 so that it is 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 bring it into an extended state.

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

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

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

As shown in FIGS. 5 (b) and 6 (b), the upper corners 152d and 152e of the side plates 152b and 152c of the movable unit 152 have a rounded shape, so that a futon or the like may be used. It is possible to prevent the object from being caught by the object to be dried.

Further, since the semicircular finger hooks 156 are formed on the edges of the side plates 152b and 152c of the movable unit 152, it is possible to easily shift from the housed state to the extended state of the movable unit 152. ..

Further, in the accommodation 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 from the auxiliary outlet 180. In addition, when the drying device 1 is not in use, the front outlet 170 is closed 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 the invasion of dust from 3. 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 on which the auxiliary outlet 180 is formed, but the present invention is not limited to this. It suffices if it is configured to cover at least the auxiliary outlet 180.

Further, at least a part of the upper plate portion 152a may be covered.

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, but the present invention is not limited to this, and the movable unit 152 can be expanded and contracted by sliding in the vertical direction (Y direction). The position of the movable unit 152 may be changed as a configuration or the like.

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

Further, a plurality of movable units 152 forming 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 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 object to be dried may be intermittently expanded. That is, for example, a swing mechanism for intermittently swinging the movable unit 152 by a predetermined control device can be provided above the nozzle unit 151.

(Structure of heating means)
The heating means included in the drying apparatus 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 the internal configuration of the drying device 1 according to the embodiment, and FIG. 9 shows the internal configuration of the heater case 400 constituting the main part of the drying device 1.

Further, a connection cord 404 is extended from both ends of the thermistor S2 and is connected to the above-mentioned 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 detection unit (substantially central portion of the straight tubular portion) of the thermistor S2 is from the position of the temperature detection portion (substantially central portion of the straight tubular portion bent in a U shape) of the thermistor S1. Is also arranged so as to be close to the surface of the heater H. Since the thermistor S1 is arranged in a direction orthogonal to the flow of the warm air at a position where it receives the warm air that has passed through the heater H, the temperature of the warm air can be efficiently detected.

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 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 detected more accurately even when the drying device 1 is used in various postures.

On the other hand, when the ventilation is stopped, the thermistor S2 mainly detects the temperature. As a result, when the ventilation is stopped, the thermistor S2 arranged at a position closer to the heater H can detect the temperature more accurately, and the safety can be improved.

The term "blower stop" as used herein means that the operator intentionally stops the blow by operating the operation panel 35 (see FIG. 1), as well as the operator's control at the time of abnormality detection or mechanical damage. Including unintentional stoppages.

Further, as shown in FIG. 8 and the like, when the drying device 1 is used in an upright posture, the thermistor S1 mainly detects the temperature when blowing air to dry 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 the ventilation is stopped, and safety can be improved.

Further, when the drying device 1 is used in a sideways posture, the thermistor S1 mainly detects the temperature when blowing air 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. As a result, when the ventilation is stopped, the thermistor S2 located above the heater H can detect the temperature more accurately, and the safety can be improved.
