<Drying unit 13>
Fig.2 (a) is the perspective view which looked at the drying unit 13 of the futon dryer 2F from diagonally upward front.
As shown in FIG. 2A, the drying unit 13 forms a ventilation space 13 </ b> P having a shape cut out from the front end side to the center at a position near the center of the front end (one end). And the rear side to which the hose 2 is connected has a box-shaped housing shape. That is, the drying unit 13 is configured by a cloth-like fiber or the like impregnated with a synthetic resin or a resin in a flat box shape (housing shape) having a bifurcated shape or a substantially U-shaped shape in a plan view. .

  When the drying unit 13 has a bifurcated shape as described above, a hose connection portion, which is a joint when supplying the airflow from the hose 2 to the drying unit 13, is provided at the central portion on the side facing the bifurcated shape. A mouth 2a (see also FIG. 4 described later) is attached. The hose connection part port 2 a plays a role of a connection attachment that connects the circular opening of the hose 2 to the rectangular opening of the drying unit 13. The hose connection port 2a is formed of, for example, a synthetic resin.

The drying unit 13 is formed with a pair of leg portions 13A extending in the longitudinal direction in the shape of an elongated box on both sides of the ventilation space 13P.
The drying unit 13 is formed with a pair of elongated leg portions 13A on both sides on the front end side, so that the warm air O is blown out to the futons (8, 9) near the center thereof. A hot air blowing space 13P is formed. Therefore, a large amount of hot air O can be applied to the futons (8, 9) near the center of the drying unit 13, and drying can be promoted.
The hot air outlet that blows out the hot air O from the drying unit 13 is formed as follows.

  A front warm air outlet 13a is formed in a rectangular hole that is long in the left-right direction at the front edge 13A1 that forms the front end surface of the pair of legs 13A of the drying unit 13. In other words, the front warm air outlet 13a is formed in a rectangular hole that is long in the direction along the mounting surface S on which the drying unit 13 is placed.

  The front warm air outlet 13a is formed in a rectangular hole that is long in the left-right direction (the direction along the mounting surface S), thereby allowing the warm air O to flow in the left-right direction in which the futons (8, 9) extend. It can be blown out from the front warm air outlet 13a. Therefore, drying of the futons (8, 9) in the left-right direction of the front warm air outlet 13a can be promoted.

Further, a concave hot air outlet 13a1 that is long on the left and right is formed at the central concave edge 13A2 that forms a ventilation space 13P between the pair of legs 13A of the drying unit 13. Since the concave hot air outlet 13a1 is a hole that is long to the left and right, the hot air O can be blown out in the left-right direction in the ventilation space 13P formed in the center of the drying unit 13.
An upper hot air outlet 13du is formed in a circular shape on the upper surface side of the drying unit 13. Since the upper hot air outlet 13du is circular, the hot air O can be evenly blown to the comforter 9.

  On the lower surface side of the drying unit 13, a lower warm air outlet 13ds is formed in a circular shape having a diameter equal to or larger than that of the upper hot air outlet 13du. Since the lower warm air outlet 13ds is a circle having a diameter equal to or larger than that of the upper hot air outlet 13du, the warm air O having a larger air volume or an air volume equivalent to that of the comforter 9 side than the mattress 8 on which moisture is likely to accumulate. Can be blown out evenly.

  On both sides of the drying unit 13, a pair of side warm air outlets 13 b are formed with long shapes in the longitudinal direction (direction along the mounting surface S). Since the pair of side warm air outlets 13b have a shape that is long in the longitudinal direction, the warm air O can be spread and blown to the comforter 9 and the mattress 8 that are located on the side of the drying unit 13.

  A rear warm air outlet 13 c is formed at the rear of the drying unit 13. By forming the rear warm air outlet 13c, the warm air O can be applied to the futons (8, 9) on the rear side of the drying unit 13.

  Here, a wind control plate is provided inside the hot air outlets (13b, 13du, 13ds) provided in the drying unit 13, and the hot air O is effectively external to the hot air outlets (13b, 13du, 13ds). It is preferable that the hot air O from the hose 2 is guided to the outside of the hot air outlets (13b, 13du, 13ds) so as to be sent. The effect of being able to spread the warm air O which blows into the comforter 9 and the mattress 8 to every corner in the comforter (8, 9) is enhanced by the wind control plate. In addition, it is good also as a structure which provides a wind-control board in at least any one of a warm air blower outlet (13a, 13a1, 13b, 13c, 13du, 13ds).

FIG.2 (b) is sectional drawing which looked at the drying mat vicinity of the futon dryer of the modification from upper direction. The drying unit according to the embodiment of the present invention may be, for example, a bag-shaped drying mat 110 instead of the above-described drying unit 13.
In this case, in the drying mat 110, for example, warm air O is supplied from the futon dryer 2 </ b> F (see FIG. 1) via the hose 102 into the outer peripheral hot air passage 111 and passes through the outer peripheral hot air passage 111. Then, the air flows through the central hot air passage 112.
A mattress 108 is placed below the drying mat 110, and a comforter 109 is hung above the drying mat 110. Then, the mattress 108 below the drying mat 110 and the comforter 109 above the drying mat 110 are dried by blowing hot air from the inside of the drying mat 110 or by the heat of the drying mat 110.

  The drying mat 110 is configured to include an outer peripheral hot air passage 111 of a hot air O passage disposed in the outer peripheral portion and a central hot air passage 112 of a hot air passage disposed in the central portion. .

  In the outer peripheral warm air passage 111, the warm air O flows (stagnates) inside to create a bulge in a cylindrical shape, and a gap is formed between the comforter 109 and the mattress 108. And the warm air which passed the outer peripheral part warm air channel | path 111 flows into the center part warm air channel | path 112, and it ventilates directly from the center part warm air channel | path 112 to the lower mattress 108 side, and drying of the mattress 108 side is performed. .

  In addition, the comforter 109 and the mattress 108 to which hot air from the central hot air passage 112 does not reach are dried by heat conduction of the outer peripheral hot air passage 111 and the central hot air passage 112.

The cover side guard part 41 (41a to 41h) is a claw-like guard part formed so as to protrude in the vertical direction at an appropriate position of the frame part W of the filter cover f. A coarse filter 61 (see FIG. 12 for details, see FIG. 12 for details) on the inner side of the cover-side guard portion 41 and the outer side (the front side of the paper surface in FIG. 9A) of the filter cover f viewed from the flat plate portion f2. (Not shown) is inserted as a prefilter. In addition, a HEPA filter 60 (details will be described later in FIG. 10B) is attached to the inner side of the filter cover f as viewed from the flat plate portion f2 via a guard column 44. Thus, by providing the cover-side guard part 41 and the guard column 44 on the filter cover f, different types of filters (specifically, for example, the HEPA filter 60 and the coarse filter 61) can be operated in the dryer main body 21. It plays a role of guarding so that it does not fall out of shape due to vibrations caused by the.
In the present embodiment, the cover-side guard portion 41 is sequentially arranged on the upper frame portion W of the filter cover f 41a and 41b, on the left frame portion W of the filter cover f 41c and 41d, and on the lower frame portion W of the filter cover f. Although 41e and 41h and eight places 41g and 41h are provided in the right frame part W of the filter cover f, it is not limited to this.
The positioning engagement protrusion 42 is a protrusion provided in the filter cover f at a position opposite to the handle portion 43 so as to protrude in the horizontal direction (left side in the drawing). The positioning engagement protrusion 42 is a protrusion for positioning the filter cover f and the dryer main body 21 in the left-right direction by engaging with a positioning engagement hole 52 (see FIG. 13 and the like described later).

FIG. 10A is a view showing a state in which the filter cover is removed from the dryer main body, and FIG. 10B is a view showing a state when the HEPA filter is mounted from the state of FIG. 10A. .
As shown in FIG. 10A, when the filter cover f is removed from the dryer main body 21, the lid engaged holes 50 (50a, 50b) are formed at positions corresponding to the lid engaging projections 40 (40a, 40b). However, a positioning engaged hole 52 is formed at a position corresponding to the positioning engaging protrusion 42.
In addition, a storage portion 53 for storing the coarse filter 61, the HEPA filter 60 (described later in detail), and the filter cover f is provided. In other words, the coarse filter 61, the filter cover f, and the HEPA filter 60 are stored in the storage unit 53. Therefore, the shape of the storage portion 53 may be formed so as to be a substantially square box-shaped concave portion in accordance with the shape of the HEPA filter 60 and the filter cover f to be stored (the rough filter 61 is a filter cover). The size fits in f). At this time, the portion in which the HEPA filter 60 is accommodated and the portion in which the filter cover f is accommodated may have a square box shape in which the portion in which the filter cover f is accommodated has a larger cross-sectional area. That is, the outer shape of the storage portion may have a substantially stepped shape in a cross-sectional view, and may have a shape in which a plurality of square boxes are stacked (see also FIG. 11A and the like described later). In the embodiment, the vertical and horizontal sizes of the storage unit 53 are set to be substantially the same as or larger than the vertical and horizontal sizes of the HEPA filter. However, regarding the thickness (depth depth) of the storage portion 53, for example, it is desirable to have a thickness of about 70 to 80% of the thickness of the stored HEPA filter 60. In this way, when the filter cover f is attached, the HEPA filter 60 is slightly compressed by the guard column 44 and the main body side guard part 51. Thereby, it can avoid that the HEPA filter 60 remove | deviates by a vibration at the time of the driving | running of the dryer main body 21, etc., or raise | generates shape loss.

FIG. 10B is a diagram showing a state when the HEPA filter is attached from the state of FIG.
As described above, the dryer main body 21 is provided with the air suction port Vc on the front surface side, and has the storage portion 53 that is recessed in a box shape so as to communicate with the air suction port Vc. The shape of the storage portion 53 is not particularly limited. Thus, by providing the air suction port Vc on the front side of the dryer main body 21, it is possible to inhale indoor air with less dust and take it into the dryer main body 21 than when provided on the rear side. ing.

  As shown in FIG. 10B, the storage unit 53 is equipped with a HEPA filter 60 (HEPA: High Efficiency Particulate Air Filter). Here, the HEPA filter 60 is defined by, for example, JIS Z 8122, “having a particle collection rate of 99.97% or more with respect to particles having a rated air volume of 0.3 μm and an initial pressure loss. Is an air filter having a performance of 245 Pa or less. Here, the size of the HEPA filter 60 used in the embodiment is, for example, 123 mm in length, 118 mm in width, and 15 mm in thickness. However, the size is not particularly limited.

FIG. 11A is a cross-sectional view taken along the line XX of FIG. 8 and illustrates a state in which the lid engaging protrusion of the filter cover and the lid engaging hole of the dryer main body according to the embodiment are engaged. . In addition, Fig.11 (a) is the figure which looked downward from the XX cross section of FIG. 9A and 9B also show positions corresponding to the XX cross section for reference. FIG. 11B is a cross-sectional view illustrating a state immediately before the lid engaging protrusion and the lid engaged hole are engaged, corresponding to FIG. FIG. 11C is a cross-sectional view illustrating a state immediately after the engagement between the lid engaging protrusion and the lid engaged hole is released, corresponding to FIG. 11A.
As shown in FIG. 11A, the lid engaging protrusion 40 (40a) of the filter cover f according to the embodiment of the present invention is substantially perpendicular to the inside of the dryer main body 21 from the flat portion f3 of the filter cover f. An engaging convex portion 40a1 is provided at a substantially distal end portion of the projecting portion 40a2 extending to the outside of the filter cover f. Correspondingly, the lid engagement hole 50 (50a) of the dryer main body 21 has an engagement recess 50a1 whose outer shape matches that of the engagement protrusion 40a1. Yes. When the filter cover f and the dryer main body 21 are engaged, specifically, a force F1 shown in FIG. 11B described later is applied to the filter cover f, and the lid engaging protrusion 40 (40a). The engagement is realized by fitting the engagement projection 40a1 into the engagement recess 50a1 of the lid engaged hole 50 (50a).
In addition, although the position where the engagement convex part 40a1 was provided was demonstrated as the substantially front-end | tip part of the projection part 40a2, it is not limited to this. For example, you may make it provide in the approximate center part of the projection part 40a2, or a substantially base end part.

  Next, a state immediately before the lid engaging protrusion and the lid engaged hole are engaged will be described with reference to FIG. When the filter cover f is attached to the dryer main body 21, the details will be described later with reference to FIG. 13. However, the user holds the handle 43 (see FIG. 9A, etc.) with his / her finger and positions the filter cover f. The engagement protrusion 42 is engaged with the positioning engagement hole 52 of the dryer main body 21 in advance. In this state, the lid engaging protrusion 40 (40a) is inserted into the storage portion 53 so as to push the filter cover f into the dryer main body 21 (direction of force F1). Then, as shown in FIG. 11 (b), the protrusion 40a2 is elastically deformed toward the inside of the filter cover f by the convex shape on the distal end side of the engagement protrusion 40a1 of the lid engaging protrusion 40 (40a). (Refer to the solid arrow), an elastic force is generated toward the outside of the filter cover f. When the insertion of the filter cover f further proceeds in this state, the engaging convex portion 40a1 of the lid engaging projection 40 (40a) is moved by the elastic force when the engaging convex portion 40a1 reaches the engaging concave portion 50a1. It fits into the engaging recess 50a1 of the lid engaged hole 50 (50a). Through the above process, the state described with reference to FIG. 11A is obtained, and the engagement between the filter cover f and the dryer main body 21 is realized.

Next, a state immediately after the engagement between the lid engaging protrusion and the lid engaged hole is released will be described with reference to FIG. From the state of FIG. 11A, the user picks the handle portion 43 (see FIG. 9A, etc.) with a finger and removes the filter cover f from the dryer main body 21 (direction of force F2). At this time, it is assumed that the positioning engagement protrusions 42 (see FIG. 13 described later for details) of the filter cover f are kept engaged with the positioning engagement holes 52 of the dryer main body 21. Then, as shown in FIG. 11 (c), the protrusion 40a2 is elastically deformed toward the inner side of the filter cover f by the convex shape on the base end side of the engagement protrusion 40a1 of the lid engaging protrusion 40 (40a). (See the solid line arrow), and an elastic force is generated toward the outside of the filter cover f. In this manner, the engagement between the engagement convex portion 40a1 of the lid engaging protrusion 40 (40a) and the engagement concave portion 50a1 of the lid engaged hole 50 (50a) is released, and the user further removes the filter cover f. The filter cover f can be removed from the dryer main body 21 by pulling up.
11A to 11C have been described by taking, for example, a cross-sectional view of the lid engaging protrusion 40a as an example. However, the other lid engaging projections 40b have the same cross-sectional configuration as FIG. 11A, which is a sectional view of the lid engaging projection 40a. Therefore, illustration and detailed description are omitted.

Arranged to do so. Further, the filter cover f is arranged so that the guard column 44 guards the HEPA filter 60 while preventing its shape from being lost. Here, in the present embodiment, the thickness (depth depth) of the storage portion 53 of the HEPA filter 60 is set to about 70 to 80% of the thickness of the HEPA filter 60 as described above. Thereby, when the filter cover f is mounted on the dryer main body 21, the HEPA filter 60 is sandwiched between the guard column 44 and the main body side guard portion 51 and slightly pressed. Further, the rough filter 61 is guarded by the claw-like cover side guard portion 41, and the rough filter 61 is prevented from being deformed. As a result, the HEPA filter 60 and the coarse filter 61 can be prevented from falling off from the storage portion 53, and can be prevented from being deformed even when vibration is applied to the dryer body 21. be able to.
Here, for example, an allele catcher (registered trademark) may be used for the coarse filter 61 serving as a prefilter. If an allele catcher is attached, it can adsorb and decompose mite and pollen allergens and decompose formaldehyde. Moreover, since it can deodorize sweat and an aging odor, and has an antibacterial deodorizing effect, it can be said to be suitable. Further, for example, a known air filter that captures coarse particles that are coarser than the HEPA filter 60 may be inserted and attached. As shown in FIG. 9A, the inner side of the coarse filter 61, that is, the filter cover f side is guarded by the flat plate portion f2 of the filter cover f, and the inner side of the coarse filter 61, that is, the dryer body 21 side.
