<Embodiment>
1. 1. Overview As shown in FIG. 1, the drying device X mainly consists of, for example, a device main body 1 that branches and discharges air into two flow paths, and two hose bodies 3 and 3 that blow the branched air. Become. Further, it is provided with a binding band 4 for bundling the power cord 171 and fixing it to the apparatus main body 1. It should be noted that the illustration of the state in which the power cord 171 is bundled is omitted. The hose body corresponds to an example of the "discharge part" of the present invention.
The drying device X may include one or more of the second hose body 3 and the binding band 4 in addition to the device main body 1 and one hose body 3, and here, the drying device X including all of them may be provided. explain.

As shown in FIG. 2B and FIG. 3, the apparatus main body 1 heats the air sucked from the intake port 11a and discharges warm air. The hose body 3 has a hose 31 having one end 31a connected to the apparatus main body 1 and flexible and expandable, and a nozzle body 32 connected to the other end of the hose 31, and is bent in a "U" shape. It is attached to the device main body 1 in such a state that it is stretched in a straight line, for example, when it is used.

The drying device X is, for example, in a state where the nozzle bodies 32, 32 of the two stretched hose bodies 3, 3 are inserted into two different parts of the two objects to be dried P or one object to be dried P. , The object to be dried P is dried by discharging warm air. The object to be dried P is, for example, a futon, a blanket, clothes, or the like.
Here, as shown in FIG. 1, the direction in which warm air is discharged from the device main body 1 is the upward direction. Further, the direction in which the hose bodies 3 and 3 mounted in parallel to the device main body 1 face each other (adjacent to each other) is the left-right direction or the width direction. Further, the direction orthogonal to the upward direction and the width direction is defined as the front-rear direction or the front-back direction.

The method of placing the drying device X in a state where the drying device X is not used, in other words, in a state where the two hose bodies 3 and 3 are attached to the device main body 1, is not particularly limited, but is shown in FIG. 1 for convenience. As described above, it is assumed that the hose body 3 is on the upper side and the operation unit 15 is on the front side or the front side.

2. 2. Branch duct First, the branch duct 20 and the hose body 3, which are the main configurations in the present embodiment, will be described, and then the apparatus main body 1 will be described in detail.

The branch duct 20 has a function of separating and supplying the discharged air to the two hose bodies 3, 3.
For example, in the present embodiment, the branch duct 20 is continuous with the mounting portion 21 mounted on the discharge port 132a of the heater case 132 and the mounting portion 21 as shown in FIGS. 3 (b) and 11 (c). It is provided with a tubular portion 22 that separates the heated air, and a connection receiving portion 23 that is provided at the tip of the tubular portion 22 and serves as a mounting seat for the connecting ring 14.
A partition wall 24 is provided inside the tubular portion 22. The partition wall 24 forms two passages in the tubular portion 22. One is the first passage 25 that guides the warm air discharged from the heater case 132 upward in the direction of the discharge (upward) almost straight, and the other is the left and right of the device main body 1. It is the second passage 26 that leads diagonally to the right and upward in the direction. As a result, although the discharge port 132a is arranged on the left side of the device main body 1, the hose bodies 3 and 3 can be arranged side by side in a well-balanced manner with respect to the center in the width direction of the device main body 1. The lead lines of the first passage 25 and the second passage 26 are indicated by arrows in order to distinguish them from the tubular portion 22 and the partition wall 24.

In the present embodiment, the shape of the opening cross section of the entrances of the first passage 25 and the second passage 26 is rectangular, and the exit side is circular.
The ratio of the opening areas at the entrances of the first passage 25 and the second passage 26 is, for example, a ratio of approximately 1: 2 in the present embodiment. On the other hand, the opening areas of the exits of the first passage 25 and the second passage 26 are the same. Further, the heights of the first passage 25 and the second passage 26 in the vertical direction are the same. Further, since the second passage extends diagonally, the second passage 26 is longer than the first passage 25.

Since the first passage 25 extends substantially along the discharge direction of the warm air discharged from the heater case 132, the pressure loss of the air flowing through the first passage 25 tends to be small. On the contrary, since the second passage 26 extends diagonally, the pressure loss tends to be larger than that of the first passage 25. Therefore, in the present embodiment, the opening area of the entrance of the first passage 25 is almost half that of the second passage 26. Thereby, the air volume of the warm air at the outlets of the first passage 25 and the second passage 26 can be made the same. Further, the temperature of the warm air at the outlets of the first passage 25 and the second passage 26 can be made substantially the same.

(2) Nozzle body The nozzle body 32 has a cylindrical shape as a whole and its cross-sectional shape is substantially elliptical. Then, the side with a large radius (major axis) of the ellipse is placed on the installation surface. In this installed state, the nozzle body 32 may be described below.
The nozzle body 32 is at least the nozzle body 33, the first flap 34 provided on the nozzle body 33 so as to be openable and closable in the direction opposite to the installation surface (hereinafter, also referred to as “upward direction”), and the nozzle body 32. It is provided with a second flap 36 provided on the nozzle body 33 so that it can be opened and closed in a direction orthogonal to the axial direction and the direction opposite to the installation surface (hereinafter, also referred to as "left-right direction"). Opening upward is also referred to as "starting up", and the open state is also referred to as, for example, "starting up state".
The first flap corresponds to an example of the "stretched portion" and the "first stretched portion" of the present invention, and the second flap corresponds to an example of the "second stretched portion" of the present invention. The open state or the start-up state corresponds to an example of the "stretched state" of the present invention. Further, the nozzle body corresponds to an example of the "discharge unit body" of the present invention, and the axial direction of the nozzle body 32 coincides with the ventilation direction of the present invention.
Further, the nozzle body 32 is provided with a holding portion 35 which can adjust the degree of raising the first flap 34 (starting angle) and holds the raised state.
Here, the nozzle body 32 includes a connecting pipe 37 and a nozzle port 38 in addition to the nozzle body 33, the first flap 34, and the second flap 36 described above, and the fragrance container 39 is attached to the nozzle port 38. There is.

(2-1) Nozzle body The nozzle body 33 has a cylindrical shape and a substantially elliptical cross-sectional shape. A connecting pipe 37 is connected to the base of the nozzle body 33 on the hose 31 side, and a nozzle port 38 is connected to the tip of the nozzle body 33.
The nozzle body 33 has a plurality of through holes along a row in the axial direction on the left and right side walls. It should be noted that these through holes constitute the sub-discharge port 32c of the nozzle body 32, and warm air is also discharged in the left-right direction. The through hole is configured such that the base side is large and the tip side is small. As a result, warm air can be evenly diffused in the left-right direction.
When the first flap 34 and the second flap 36 are in the closed state, the nozzle body 33 has recessed portions 33d and 33f on the peripheral wall to form a uniform appearance as a whole. Thereby, the design of the nozzle body 32 can be enhanced. The nozzle body 32 may be provided so as to be rotatable with respect to the hose 31, or may be provided so as not to be rotatable.

(2-2) First Flap The first flap 34 is provided on the nozzle body 33 so as to extend in a direction (first stretching direction) intersecting (including cases where it is orthogonal to) the axial direction of the nozzle body 33. ing.
As shown in FIG. 7, when the first flap 34 is covered with the object to be dried P such as a futon in the standing state, the first flap 34 lifts the object to be dried P and reaches the air discharged from the drying device X. It has the function of expanding the space.
The first flap 34 has, for example, a wide "U" -shaped cross-sectional shape obtained by cutting a cylindrical member having almost the same cross-sectional shape (elliptical shape) as the nozzle body 32 in half on a surface including the long axis of the ellipse. It is presented.
The first flap 34 rotates with the hose 31 side of the nozzle body 32 as the center of rotation and the tip end side (discharge port 32b side) as the free end. Reference numeral 34a indicates a rotation axis. The nozzle body 32 is placed on the installation surface so that the side on which the first flap 34 is provided faces upward. The rotation shaft 34a extends in a direction parallel to the installation surface (left-right direction).

The first flap 34 is superposed on the closed second flap 36 (detailed below) when not raised. On the left and right peripheral walls of the first flap 34, a notch portion 34b is formed on the rotation shaft 34a side and at the lower end thereof. The second flap 36 engages with the notch portion 34b. As a result, the raised state of the first flap 34 is maintained. The installation surface contains the object to be dried P.

(2-3) Second Flap The second flap 36 comes into contact with the first flap 34 and stretches in a direction different from that of the first flap 34 (second stretching direction).
The second flap 36 is extended so as to open left and right outward in a direction different from the rising direction of the first flap 34.
As a specific configuration of the second flap 36, for example, the second flap 36 has a cross section that covers the vicinity of the elliptical cross-sectional shape of the nozzle body 32 from the outer peripheral surface having a large radius to the outer peripheral surface having a small radius. It is a / 4 arc-shaped plate-shaped member.
The second flap 36 has the hose 31 side of the nozzle body 32 as the center of rotation and the tip side (discharge port side) as the free end. Reference numeral 36a is a rotation axis. As a result, the sub-discharge port 32c of the nozzle body 32 is exposed, and warm air can be sent to the side as well.
On the other hand, the second flap 36 is overlapped with the outer peripheral wall of the nozzle body 32 in a state of not rotating outward, and is particularly folded so as to be buried in the recessed portion 33f of the nozzle body 33. As a result, the joint between the two becomes smooth, and the design can be enhanced.
As will be described later, the second flap 36 also has the function of the holding portion 35.

(2-4) Nozzle port The nozzle port 38 is connected to the tip of the nozzle body 33 and constitutes a main discharge port 32b for discharging warm air from the nozzle body 32 (see (c) in FIG. 7). The nozzle port 38 fixes the fragrance accommodating body 39 that extends the nozzle body 33 inward.

(2-5) Connection pipe The connection pipe 37 has a cylindrical shape, and its cross-sectional shape is similar to the substantially elliptical shape of the nozzle body 33. The connecting pipe 37 has a bulky portion 37a on the hose 31 side of the nozzle body 33 and on the installation surface side.
The bulky portion 37a has an "L" shape that extends toward the tip side after being extended toward the installation surface side. The bulky portion 37a engages with the support portion 111d of the housing 11 of the apparatus main body 1 (see FIG. 10). As a result, the hose body 3 can be detachably attached to the device main body 1.
When the second flap 36 is closed, the protruding portion 36b is on the tip end side of the nozzle body 32. The heights of the bulky portion 37a and the protruding portion 36b from the installation surface to the nozzle body 32 are substantially the same. Therefore, when the second flap 36 is closed or slightly opened, the main discharge port 32b can be directed parallel to the installation surface, and warm air can be distributed far away. Further, it is possible to prevent the nozzle body 32 from slipping / rattling.

(2-6) Protruding portion A protruding portion 36b of a ridge is provided at a portion grounded to the installation surface of the second flap 36. The extending direction of the protrusion 36b is a direction parallel to the axial direction of the nozzle body 33 when the second flap 36 is open outward, and the axial direction of the nozzle body 33 when the second flap 36 is closed. The direction is orthogonal to. Since the protruding portion 36b is ribbed, the protruding portion 36b bites into the installation surface to prevent slipping. As a result, even if the installation surface is soft such as a futon, the nozzle body 32 can be placed (arranged) on the installation surface in a stable state.

(2-7) Fall Prevention When the second flap 36 is opened, when the nozzle body 32 is tilted, the vicinity of the tip of the second flap 36 is stretched against the installation surface and can withstand the tilting movement. In particular, when the first flap 34 is opened high and upward, the center of gravity of the nozzle body 32 moves upward and is pulled by the object to be dried P covered, and the placed state becomes unstable. Therefore, if the second flap 36 is opened outward, it is easy to withstand the tilting movement. In order to prevent the nozzle body 32 from rotating in the axial direction, it is preferable to open the second flap 36 as wide as possible to the left and right.

(2-8) A notch 36c is formed on the first flap 34 side of the holding portion second flap 36 and on the rotation shaft 36a side of the second flap 36. The notch portion 32a of the first flap 34 engages with the notch portion 36c. As a result, the first flap 34 in the raised state (open state) is held so as not to be lowered (closed). On the other hand, the second flap 36 is maintained in a laterally open state by engaging with the first flap 34. That is, by engaging with each other, the open state is mutually maintained.
The first flap 34 is raised to a desired degree, and then the second flap 36 is opened to engage the notches 32a and 36c with each other to lock the raised state of the first flap 34. Can be held in.

(2-9) Since the rib first flap 34 is covered with the object to be dried P, a load is also applied to the second flap 36. Therefore, a reinforcing rib 36d is provided on the peripheral wall of the second flap 36 on the first flap 34 side. The rib 36d extends from the rotation shaft 36a toward the tip end side in a ridge.

7. Usage pattern A drying device set that dries the object to be dried may be used by using the drying device X and a drying bag for accommodating the object to be dried.
In this case, the drying device set includes a drying device including two or more discharge units 3 and a drying bag in which the object to be dried is housed, and the drying bag has the two or more discharge units inserted into the bag. Alternatively, it is preferable to have a hot air supply port to be connected. As a result, it is possible to improve the range in which the warm air reaches in the drying bag.
That is, as a drying bag for the drying device set, for example, as in Patent 6307670, "a bag for a futon dryer having the same structure with a surface fastener arranged on the edge of the connecting surface is placed in two upper and lower stages with the surface fastener. It is configured to be able to be connected and put in close contact with each other, and each of the upper and lower two-stage futon dryer bags is equipped with a hot air connection port for sending hot air from the main body of the futon dryer on one side of the bag. A "bag for a futon dryer that kills ticks" has been proposed, which is provided with a fastener for putting in and taking out the bag on the front of the machine bag.
In this drying bag, since hot air is supplied to one bag by one temperature connection port, there is a problem that the hot air does not sufficiently reach the inside of the bag. However, this problem is caused by the above-mentioned drying device. It is solved by the set.
Hereinafter, a drying bag containing a futon, which is an example of an object to be dried, will be described.

(1) Drying bag As shown in FIG. 17, the drying bag 9 has a bag main body 91 and an opening / closing tool 93 that can open and close the bag main body 91, and is a nozzle body of two hose bodies 3 of the drying device X. The bag body 91 has a warm air supply port 95 for inserting the 32 inside. Here, there are two hot air supply ports 95, and the two nozzle bodies 32 are arranged inside the bag main body 91 by using separate hot air supply ports 95.

The bag body 91 has a bag shape having a storage space for accommodating a futon inside. The bag body 91 is made of a woven fabric material (polyester fiber, nylon fiber, chemical fiber such as acrylic fiber, natural fiber, a cloth material composed by combining these), a resin film material, a paper material, a non-woven material, and the like. There is. The bag body 91 is configured to be breathable. The bag body 91 is configured to have elasticity. Here, the bag body 91 is made of, for example, a woven fabric material using polyester fibers.
The bag body 91 has a box shape, and has a rectangular cuboid shape in which the dimension in one direction (for example, the thickness direction of the futon) is smaller than the two dimensions in the direction orthogonal to the one direction.
That is, the bag main body 91 has a rectangular lower surface portion 911 and an upper surface portion 912 facing the main surface of the futon and having a short side in the longitudinal direction of the futon, and side surface portions 913 to connect the lower surface portion 911 and the upper surface portion 912. It has 916. The side surface portion connecting the short sides of the lower surface portion 911 and the upper surface portion 912 is the short side surface portion 913, 914, and the side surface portion connecting the long sides of the lower surface portion 911 and the upper surface portion 912 is the long side surface portion 915, 916. And. Here, the short side surface portion 913 is one of the pair of short side surface portions 913 and 914, and is also referred to as the first side surface portion 913, and the short side surface portion 914 is the other of the short side surface portions 913 and 914, and the second It is also referred to as a side surface portion 914, and the long side surface portion 915 is also referred to as a third side surface portion 915.
Here, the extending direction of the short side of the rectangular lower surface portion 911 and the upper surface portion 912 is defined as the "length direction" with reference to the accommodated futon, and the long side of the lower surface portion 911 and the upper surface portion 912 is extended. The direction is defined as the "width direction", and the direction connecting the lower surface portion 911 and the upper surface portion 912 (the direction orthogonal to the lower surface portion 911 and the upper surface portion 912) is defined as the "thickness direction".
The bag body 91 is configured such that the upper surface portion 912 can be opened and closed with respect to the lower surface portion 913 in order to put in and take out the futon. That is, the upper surface portion 912 can be opened and closed with respect to the lower surface portion 911 along the longitudinal direction (the width direction in the futon) of the long side surface portion 916.
The dimension in the length direction of the bag body 91 (“L” in FIG. 17) is larger than the dimension in the length direction of the futon when the futon is folded in three, and the dimension of the futon when the futon is folded in two. It is smaller than the dimension in the length direction. As a result, the user can eliminate the need to fold the futon in half when accommodating the futon.

The opening / closing tool 93 includes point fasteners such as dot buttons, wire fasteners such as slide fasteners, zippers and chucks, and fasteners such as hook-and-loop fasteners such as Magic Tape (registered trademark), Velcro (registered trademark) and Quicklon (registered trademark). Belts and the like can be used, and wire fasteners are used here. The code of the wire fastener is also "93".
The wire fastener 93 is provided at the openings of the three side surface portions of the short side surface portions 913 and 914 and the long side surface portion 915 of the bag main body 91, and facilitates the loading and unloading of the futon. The wire fastener 93 is provided so as to be continuous over the entire length in the width direction of the short side surface portions 913 and 914 and in the length direction of the long side surface portion 915. That is, the line fastener 93 is provided in a "C" shape at the opening of the "C" shape (a concept including the "U" shape and the "U" shape). As a result, the lower surface portion 911 and the upper surface portion 912 can be deployed so as to face the installation surface (so that the projected area of the bag body is doubled). This makes it easy to put in and take out the futon.
The end portion of the wire fastener 93 is in the vicinity of the connecting portion between the short side surface portion 913, 914 and the long side surface portion 915. That is, the bag main body 91 can be opened by three continuous side surface portions 913, 914, 915 excluding the long side surface portion 916 of the bag main body 91, and the bag main body 91 has a large opening. More specifically, the upper surface portion 912 can be opened and closed with respect to the lower surface portion 911 by forming a crease in a virtual line connecting one end portion and the other side end portion of the wire fastener 93. This makes it easy to put in and take out the futon.
The wire fastener 93 is provided substantially at the center of the short side surface portions 913 and 914 and the long side surface portions 915 in the thickness direction. As a result, it can be used without worrying about the top and bottom of the bag body 91.

The hot air supply port 95 is provided on at least one of the short side surface portions 913 and 914 on the first short side surface portion (here, 913). As a result, when arranging the nozzle body 32 in the drying bag 9, the user can work on one side in the width direction of the drying bag 9, and the nozzle body 32 can be easily (short time) arranged. There is no need to move the location for the user to place it.
Two hot air supply ports 95 are provided on the first short side surface portion 913 at intervals in the length direction (“L3” in FIG. 17). The two hot air supply ports 95 are provided so as to be symmetrical with respect to the center in the length direction of the first short side surface portion 913 (so that the distance from the center is the same). As a result, the nozzle body 32 can be arranged near the center in the length direction of the accommodated futon, and the uneven drying of the futon can be reduced.
To be precise, the hot air supply port 95 shows an example provided at the connection portion between the first short side surface portion 913 and the lower surface portion 911, but if it is provided on the first short side surface portion 913 side, good.
The hot air supply port 95 may be provided with an opening / closing tool 97 for opening / closing the opening. As the opening / closing tool, similar to the above opening / closing tool 93, a point fastener such as a dot button, a slide fastener, a zipper, a wire fastener such as a chuck, a magic tape (registered trademark), a velcro (registered trademark), and a quicklon (registered trademark). Fasteners such as hook-and-loop fasteners such as), belts, etc. can be used, and wire fasteners are used here. As a result, it is possible to prevent the bag body 91 from being torn due to some member being caught in the warm air supply port 95. Further, when the wire fastener is used as the opening / closing tool 93, it is possible to prevent the hot air from coming out from the hot air supply port 95 during the drying use.
The sizes of the two hot air supply ports 95 (“L2” and “L4” in FIG. 17) are the same, and at least the passage of the nozzle body 33 is allowed. The distances (“L1” and “L5” in FIG. 17) from both ends of the bag main body 91 of the two hot air supply ports 95 in the length direction are not particularly limited, but are the same here, and the hot air supply is performed. It is almost the same size as the mouth 95. The distance between the two hot air supply ports 95 (“L3” in FIG. 17) is not particularly limited, but here it is smaller than the size of the hot air supply port 95.

(2) The futon used is housed in the drying bag 9 in a tri-folded state. As a result, the futon is divided into three in the length direction, and the first end portion 971 (upper surface) of one end in the length direction and the intermediate portion 973 (upper surface) in the length direction come into contact with each other and are in the middle. The portion 973 (lower surface) and the second end portion 975 (lower surface) come into contact with each other. As a result, the two upper and lower gaps face the first short side surface portion 913, and the two nozzle bodies 32 from one side in the width direction (first short side surface portion 913 side) are placed on the futon 2 in the drying bag 9. It can be placed in two gaps. Further, if the futon is lifted by the nozzle body 32 in the gap, warm air can be spread more. The gap between the first end portion 971 and the intermediate portion 973 is the lower gap, and the gap between the intermediate portion 973 and the second end portion 975 is the upper gap.
One first nozzle body 32A of the drying device X is inserted into the lower gap, the other second nozzle body 32B is inserted into the upper gap, and warm air is discharged from each nozzle body 32. As a result, the warm air discharged from the first nozzle body 32A spreads in the lower gap and flows out of the gap through the gap. Further, the warm air discharged from the second nozzle body 32B also spreads in the upper gap and flows out of the gap through the gap. In this way, warm air is discharged over a wide range in the drying bag 9.

The discharged warm air is transmitted from the part of the folded futon facing the upper and lower gaps to the inside of the futon, and the entire futon can be efficiently dried.
Further, it has been confirmed that the mites in the futon are killed by raising the temperature of the warm air (for example, 50 ° C.) and operating for a predetermined time (for example, 30 minutes to 3 hours).
Since the bag main body 91 is provided with the wire fastener 93 over the entire length of the three continuous side surface portions 913, 914 and 915 and the bag main body 91 is made of a bendable material, the upper surface portion 912 is a long side surface portion 916. It can be folded back along the total length in the width direction of. As a result, for example, as shown in FIG. 19, the futon is cleaned by using a vacuum cleaner while the upper surface portion 912 is in the unfolded state (open state) and the futon is placed on the lower surface portion 911 and the upper surface portion 912. It can be done and the mites can be removed from the duvet so that the carcasses such as mites do not scatter on the floor or the amount of clutter is reduced.
