<First Embodiment>
Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a perspective view seen from the front and a perspective view seen from the rear of the futon dryer according to the first embodiment. In the futon dryer 1, an operation panel 5 is arranged on the upper surface of a housing 2 installed on the floor or the like, and a power cord 6 is led out on the back surface.

  A suction port 4 is provided in the lower part of one side surface of the housing 2, and a handle portion 2 b that is gripped when the housing 2 is carried is recessed in the upper part. A lid 3 a that opens and closes a storage unit 3 (see FIG. 3), which will be described later, is provided at the lower part of the front surface of the housing 2. An opening 2 a through which the hose 15 is led out opens at the upper part of the front surface of the housing 2.

  The hose 15 has flexibility, and the pull-out length drawn from the opening 2a is variable. In the present embodiment, the hose 15 is formed in a bellows shape capable of maintaining a bent shape by a resin molded product, and the length of the pull-out from the opening 2a is varied by expansion and contraction. The outer diameter of the hose 15 is, for example, about φ50 mm to φ100 mm so that the user can easily grasp and pull it out.

  FIG. 3 shows a side sectional view of the futon dryer 1. A housing 3 for housing the nozzle 20 (see FIG. 5) and the drying mat 7 (see FIG. 10) is provided in front of the lower part in the housing 2. The lid 3a on the front surface of the storage unit 3 is opened and closed, and the nozzle 20 (see FIG. 4) and the drying mat 7 (see FIG. 10) are put in and out.

  The drying mat 7 is formed in a bag shape having air permeability, and is folded and stored in the storage unit 3 to be spread during use. One end of the drying mat 7 is provided with a connection port 7a (see FIG. 10) of the hose 15, and hot air is supplied from the hose 15 as will be described later.

  A blower duct 11 extending in the vertical direction is formed at the rear portion in the housing 2. A blower fan 12 is disposed below the blower duct 11. The blower fan 12 is formed of a sirocco fan, and is arranged with an intake port (not shown) facing the intake port 4 (see FIG. 2). An air flow outlet 11a is opened at the upper end of the air duct 11, and a hose 15 is connected to the outlet 11a.

  A heater 13 is disposed between the blower fan 12 of the blower duct 11 and the outlet 11a. The heater 13 heats the airflow flowing through the air duct 11, and warm air is sent out through the hose outlet 15 a at the tip of the hose 15.

  Further, an ion generator 14 that generates ions to be discharged into the air duct 11 is disposed in the housing 2. The ion generator 14 has a pair of discharge electrodes (not shown) facing the air duct 11. The discharge electrode generates a corona discharge by applying a high voltage having an AC waveform or an impulse waveform.

A positive voltage is applied to one of the discharge electrodes, and water molecules in the air are ionized by corona discharge to generate hydrogen ions. This hydrogen ion is clustered with water molecules in the air by solvation energy. Thereby, positive ions of air ions composed of H ⁺ (H ₂ O) m (m is 0 or any natural number) are released.

A negative voltage is applied to the other discharge electrode, and oxygen molecules or water molecules in the air are ionized by corona discharge to generate oxygen ions. This oxygen ion is clustered with water molecules in the air by solvation energy. Thus, negative ions of air ions composed of O ₂ ⁻ (H ₂ O) n (n is an arbitrary natural number) are released.

H ⁺ (H ₂ O) m and O ₂ ⁻ (H ₂ O) n aggregate on the surface of airborne bacteria and odorous components and surround them. Then, as shown in the formulas (1) to (3), the active species [.OH] (hydroxyl radical) and H ₂ O ₂ (hydrogen peroxide) are aggregated and formed on the surface of the microorganism or the like by collision. Destroy airborne bacteria and odorous components. Here, m ′ and n ′ are arbitrary natural numbers. Therefore, by sending positive ions and negative ions through the hose 15, sterilization and odor removal of the futon can be performed.

H ⁺ (H ₂ O) m + O ₂ ⁻ (H ₂ O) n → OH + 1 / 2O ₂ + (m + n) H ₂ O (1)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ 2 OH + O ₂ + (m + m ′ + n + n ′) H ₂ O (2)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ H ₂ O ₂ + O ₂ + (m + m ′ + n + n ′) H ₂ O (3)

  The futon dryer 1 can send hot air from the hose 15 as shown in FIG. 2 and can send hot air from the nozzle 20 connected to the tip of the hose 15 as shown in FIG.

  5, 6, 7 and 8 show a perspective view, a top view, a side sectional view and a front view of the nozzle 20, respectively. 7 is a side cross-sectional view taken along the line AA of FIG. The nozzle 20 is attachable to and detachable from the tip of the hose 15, and a fitting portion 21 that is fitted to the hose 15 and opens the connection port 20 c is provided at one end.

  The fitting portion 21 is externally fitted to the tip of the hose 15, and a locking claw 22 that can tilt in the radial direction is provided on the outer peripheral surface. The nozzle 20 is attached by locking the locking claw 22 in an annular groove 15a (see FIG. 3) formed on the outer peripheral surface of the tip of the hose 15. At this time, the nozzle 20 is connected so as to be rotatable in the circumferential direction as indicated by the broken line 20 'in FIG.

  A widened portion 23 is provided on the downstream side of the fitting portion 21 of the nozzle 20. The widened portion 23 is gradually widened in the X direction (first direction) on the downstream side in the drawing, and a nozzle outlet 20a (blower) is opened at the tip. Further, the widened portion 23 is provided with a narrowed portion 24 and a parallel portion 25. The throttle part 24 is gradually narrowed in the Z direction (second direction) orthogonal to the X direction on the downstream side, and throttles the flow path of the nozzle 20. The parallel portion 25 is formed downstream of the throttle portion 24, and the inner wall of the nozzle 20 facing the Z direction is formed in parallel.

  Thereby, the nozzle blower outlet 20a is formed in flat shape, and the opening area of the nozzle blower outlet 20a is smaller than the opening area of the connection port 20c. For this reason, since the airflow flowing through the nozzle 20 is gradually expanded in the X direction by the widening portion 23, it spreads to the side, and the opening area of the nozzle outlet 20 a is narrowed, so that the flow velocity is increased. Although the narrowed portion 24 and the parallel portion 25 are formed in the widened portion 23, the widened portion 23 having the parallel portion 25 may be formed downstream of the narrowed portion 24.

  Further, the upper surface shape at the tip of the widened portion 23 is curved with a predetermined radius of curvature, and the radius of curvature is small at both ends in the X direction. For this reason, the both ends 20b of the nozzle outlet 20a are opened toward the side.

  A rib 26 is provided in the widened portion 23 so as to stand at the center in the X direction. The rib 26 extends in the normal direction of the connection port 20 c and is bridged between inner walls facing the Z direction of the nozzle 20. Thereby, the airflow which distribute | circulates the nozzle 20 is guided by the rib 26 and both side walls, and an airflow can be smoothly spread and sent ahead from the nozzle blower outlet 20a. At this time, if a plurality of ribs 26 are provided radially, the flow path resistance is increased, and therefore, in the present embodiment, one rib 26 is provided at the center in the X direction.

  In the futon dryer 1 having the above-described configuration, when the blower fan 12, the heater 13, and the ion generator 14 are driven, outside air flows into the blower duct 11 from the suction port 4. The airflow flowing through the air duct 11 is heated by the heater 13 and includes ions generated by the ion generator 14. And the warm air containing an ion is sent out from the hose blower outlet 15a and the nozzle blower outlet 20a.

  FIG. 9 is a view showing a state when drying the futon using the nozzle 20 by the futon dryer 1. The nozzle 20 attached to the tip of the hose 15 is inserted between the mattress 31 and the comforter 32 with the longitudinal direction (X direction) of the nozzle outlet 20a being horizontally arranged. The warm air sent out from the nozzle outlet 20 a is throttled by the nozzle 20, so that the flow velocity is large and is widened in the horizontal direction by the widening portion 23. Thereby, warm air spreads over a wide range between the mattress 31 and the comforter 32, and the mattress 31 and the comforter 32 are dried and sterilized and deodorized by ions.

  Moreover, since the nozzle 20 is narrowly formed in the up-down direction (Z direction) by the throttle portion 24, the front surface of the nozzle outlet 20a may be blocked by the comforter 32 containing moisture. At this time, since a space is formed between the mattress 31 and the comforter 32 on the side of the nozzle 20, warm air is sent from the side end portion 20b of the nozzle outlet 20a toward the side space. The warm air sent out from the side end 20b spreads between the mattress 31 and the comforter 32 and advances forward. Therefore, even when the front surface of the nozzle outlet 20a is blocked, the load on the blower fan 12 can be reduced.

  In addition, since the parallel part 25 with the parallel inner wall facing the Z direction is provided downstream of the throttle part 24, the comforter 32 is arranged horizontally on the parallel part 25 and is inclined in front of the nozzle 20. Thereby, obstruction | occlusion of the front surface of the nozzle blower outlet 20a by the comforter 32 can be suppressed.

  FIG. 10 is a view showing a state when drying the futon using the drying mat 7 by the futon dryer 1. The drying mat 7 is spread and spread on the mattress 31 (see FIG. 9), and the tip of the hose 15 is connected to the connection port 7a, and the comforter 32 is laid on the mat. The warm air sent out from the hose outlet 15a passes through the surface of the breathable drying mat 7 and is blown out from the entire surface. Thereby, the mattress 31 and the comforter 32 are dried, and sterilization and deodorization by ions are performed.

  FIG. 11 is a diagram illustrating a state when clothes are dried by the futon dryer 1. The nozzle 20 is attached to the tip of the hose 15 and warm air is sent out from the nozzle outlet 20a toward the clothes 33 hung in the room or bag. Thereby, the clothing 33 can be dried and sterilized. In addition, sterilization of the inside of a basket or the like can be performed.

  At this time, when the width of the garment 33 is narrow, such as when there is only one garment 33, the nozzle 20 is rotated in the circumferential direction so that the nozzle outlet 20a extends in the vertical direction as shown in FIG. It may be arranged to extend. Thereby, it can concentrate on the clothing 33 with a narrow width | variety, and can apply the warm air containing an ion.

  In addition, warm air and ions can be sent into the room by the futon dryer 1 to perform room heating and sterilization.

Next, the drying performance of the futon drying using the drying mat 7 and the futon drying using the nozzle 20 was examined. The sample was sprayed with 100 g of water on the mattress 31, the comforter 32 was doubled and 100 g of water was sprayed on the lower comforter (200 g in total). The amount of warm air sent from the nozzle outlet 20a is about 0.8 m ³ / min, the temperature is about 52 ° C., and the drying time is 60 minutes. The drying performance was examined by the weight difference between the samples before and after drying.

  Further, the diameter D of the connecting port 20c of the nozzle 20 is 64 mm, the width W in the X direction of the nozzle outlet 20a is 125 mm, the height H in the Z direction of the nozzle outlet 20a is 15 mm, and the length L of the nozzle 20 in the Y direction. Is 110 mm.

  According to this, the average value of the weight difference between the samples before and after drying was 188 g (drying rate 94%) when the drying mat 7 was used, and 172 g (drying rate 86%) when the nozzle 20 was used. Therefore, the futon drying using the nozzle 20 was able to obtain a drying performance of 90% or more as compared with the futon drying using the drying mat 7.

  For this reason, simple futon drying can be performed by the nozzle 20 according to the user's selection, and reliable drying of the futon can be performed to every corner by the drying mat 7.

  According to the present embodiment, the nozzle 20 is gradually widened in the X direction (first direction) by the widened portion 23 and is narrowed in the Z direction (second direction) orthogonal to the X direction, so that the nozzle outlet 20a (outlet) The opening area is smaller than the opening area of the connection port 20c. For this reason, warm air with a large flow velocity spreads sideways and is sent between the mattress 31 and the comforter 32. Therefore, the futon can be dried without using the drying mat 7, and the convenience of the futon dryer 1 can be improved.

  Further, since the nozzle outlet 20a opens laterally at both end portions 20b in the X direction, the load on the blower fan 12 can be reduced even when the front surface of the nozzle outlet 20a is blocked by the comforter 32. it can.

  The widened portion 23 has a rib 26 erected at the center in the X direction, and the rib 26 extends in the normal direction of the connection port 20c and is bridged between the inner walls of the nozzle 20 facing the Z direction. Thereby, airflow can be smoothly spread from the nozzle blower outlet 20a, and it can send out ahead. Further, since the number of ribs 26 is one, an increase in channel resistance can be suppressed.

  Further, the nozzle 20 has a narrowed portion 24 whose downstream side is gradually narrowed in the Z direction, and a parallel portion 25 whose inner walls are opposed to the Z direction downstream of the narrowed portion 24 in parallel. Thereby, the nozzle 20 whose opening area of the nozzle outlet 20a is smaller than the opening area of the connection port 20c can be easily realized. Moreover, it can suppress that the front surface of the nozzle blower outlet 20a is obstruct | occluded with the comforter 32 by the parallel part 25, and can reduce the load of the ventilation fan 12 more.

  Moreover, the hose 15 is formed in a bellows shape that holds a bent shape, and the fitting portion 21 of the nozzle 20 is fitted in the hose 15 and can be rotated in the circumferential direction. For this reason, the clothes 33 and the like can be easily dried with the hose 15 facing upward. Moreover, the nozzle blower outlet 20a is arrange | positioned so that it may extend in the vertical direction, and it can concentrate on the clothing 33 with a narrow width | variety of a horizontal direction, can apply a warm air, and can reduce drying time.

  In addition, the nozzle 20 has a locking claw 22 that can be tilted in the radial direction on the outer peripheral surface, and an annular groove portion 15b that locks the locking claw 22 on the outer peripheral surface of the hose 15 is provided. It is possible to easily realize the nozzle 20 that performs the operation. The nozzle 20 may be fitted in the hose 15 so that the locking claw provided on the outer peripheral surface of the hose 15 is locked in the groove provided on the outer peripheral surface of the nozzle 20.

  Moreover, since the ion generator 14 which generate | occur | produces the ion discharge | released in the ventilation duct 11 was provided, disinfection of the futon, the clothing 33, etc. can be performed easily.

For convenience of explanation, the same reference numerals are given to the same parts as those in the first embodiment shown in FIGS. In the present embodiment, the air holes 27 are provided in the nozzle 20 as compared to the first embodiment. Other parts are the same as those in the first embodiment.

  The vent holes 27 are provided on both side walls facing the X direction (see FIG. 8) of the widened portion 23 of the nozzle 20, respectively. Therefore, when the front surface of the nozzle outlet 20a (see FIG. 7) is blocked by the comforter 32 (see FIG. 9), warm air is sent out from the vent hole 27 toward the side space of the nozzle 20. . Therefore, the load on the blower fan 12 can be further reduced.

In the present embodiment, the parallel portion 25 (see FIG. 7) is omitted from the first embodiment. Other parts are the same as those in the first embodiment.

  The widened portion 23 of the nozzle 20 is gradually widened in the X direction (see FIG. 6) on the downstream side adjacent to the fitting portion 21, and the nozzle outlet 20a is opened at the tip. Further, the narrowed portion 24 is gradually narrowed in the Z direction on the downstream side adjacent to the fitting portion 21 and opens the nozzle outlet 20a at the tip. Accordingly, the narrowed portion 24 is formed by the widened portion 23, and the opening area of the nozzle outlet 20a is smaller than the opening area of the connecting port 20c.

  Therefore, the same effect as the first embodiment can be obtained. At this time, since the wall surface facing the Z direction of the throttle portion 24 is inclined, the front surface of the nozzle outlet 20 a is easily blocked by the comforter 32 disposed on the throttle portion 24. For this reason, it is more desirable to provide the parallel part 25 downstream of the throttle part 24 as shown in the first embodiment.

  In the present embodiment, the nozzle 20 may be provided with a vent hole 27 (see FIG. 12) similar to that of the second embodiment.
