Thus, since the external inflow part is formed in the part which cannot be heated and dried by the warm air passing through the air passage in the exterior body, the entire placement part of the futon dryer can be effectively warmed and dried.
Alternatively, the external inflow portion includes a first external passage extending from the discharge portion toward the suction portion, and a second external passage extending so as to intersect the first external passage and opening on a side surface of the exterior body. It is preferable to have. If it does in this way, since it acts so that a warm air may circulate, the mounting part of the futon dryer in a mattress can be dried more certainly.

  In addition, the discharge ports are provided on both sides of the end surface of the discharge portion, and the discharge passages branched from the blower passage are partitioned and connected to each other, and at least a part of the external inflow portion is formed between the discharge passages. It is preferable. If it does in this way, the lower part whole surface of the discharge part in a mattress can be dried reliably.

  In the futon dryer of the present invention, since it is not necessary to use an air mat, the number of parts can be reduced and the usability can be enhanced. Moreover, since the heat of the warm air heated by the heating means is transmitted to the mattress through the bottom wall of the exterior body, the placement portion of the mattress dryer in the mattress can also be dried.

  In the exterior body configured as described above, the blades 57A and 57B, which are blowing members, and the driving member are used as blowing means for sucking outside air into the internal blowing passage 38 from the suction ports 17A and 17B and discharging them from the discharge ports 36A and 36B. A drive motor 58 is provided. Further, a heater 60 is provided as a heating means for heating the outside air sucked from the suction ports 17A and 17B.

  The blades 57 </ b> A and 57 </ b> B and the drive motor 58 constituting the air blowing means are disposed in the suction portion 15. Among them, the blades 57A and 57B are disposed in the blade cases 40A and 40B constituting the first internal passages 39A and 39B, respectively. These blades 57A and 57B are sirocco fans that are symmetrical with respect to the left and right lines, rotate in the same direction as viewed from one side, and send the outside air sucked in from both sides in the axial direction toward the second internal passage 43 in the radial direction. To do. The drive motor 58 is a capacitor motor having a single rotary shaft 59 projecting from both sides. The drive motor 58 is disposed at the center between the pair of suction ports 17A and 17B so that the rotary shaft 59 extends along the outside air suction direction Y. The blades 57A and 57B are fixed to both ends of the rotating shaft 59, respectively. In the present embodiment, the blades 57A and 57B are used as the blowing members, but any member that can blow air by taking in outside air may be used. Further, the drive motor 58 may be configured to integrally rotate and drive the two rotary shafts 59 and 59 having the same axis line.

  The heater 60 is a nichrome wire heater in which a nichrome wire is wound around the heater cover 61. The heater 60 is disposed in a heater case 44 that constitutes a second internal passage 43 in the dryer body 11. As a result, the heater 60 is disposed on the upstream side of the hinge connection portion 20 in the internal air passage 38 in a region excluding the projection surface facing the inside from the discharge ports 36A and 36B.

  In addition, the heater case 44 that constitutes a part of the second internal passage 43 is disposed on the second and third bulging portions 54 and 56 in the dryer main body 11. Further, a portion of the second internal passage 43 and the branch passage 49 excluding the region where the external inflow portion 51 is formed, that is, at least a part on the downstream side of the heater 60 is formed on the bottom wall 12a and the top wall 14b of the dryer body 11. The structure is facing. Further, the third internal passages 50 </ b> A and 50 </ b> B are configured by a discharge member 26 including a pair of cases 27 and 28. Therefore, the heat of the warm air heated by the heater 60 is transmitted to the outside through the bottom walls 12 a and 27 a and is transmitted to the outside through the top wall 14 b and the recess 33. That is, in the present invention, facing means a configuration in which the heat of the heated warm air can be transmitted through the bottom walls 12a and 27a, the top wall 14b, and the recess 33. Therefore, even if the gap is formed between the heater case 44 and the bottom wall 12a and the top wall 14b, any configuration that can transfer heat is included in the present invention.

  Thus, since the futon dryer 10 of this embodiment is provided with the suction inlets 17A and 17B on both sides of the suction part 15 and provided with the blades 57A and 57B respectively, the blades 57A and 57B having a small diameter are provided. A predetermined air volume can be obtained with certainty. As a result, it is possible not only to prevent the entire size including the suction portion 15 from being increased, but also to reduce the size. In addition, since the drive motor 58 is disposed so that the rotation shaft 59 extends along the suction direction Y located in a direction orthogonal to the blowing direction X, the drive motor 58 is positioned at the center of the suction ports 17A and 17B. Can be made. Further, a drive motor 58 having a rotating shaft 59 protruding in both directions is used. Therefore, the number of parts can be reduced, and the suction portion 15 can be downsized. Moreover, the center of gravity of the product can be positioned in the center and on the back surface 15a side without being biased with respect to the suction portion 15.

  In addition, since the pair of first internal passages 39A and 39B are joined together by the second internal passage 43 and the heater 60 is disposed in the second internal passage 43, the outside air sucked from two directions is 1 Heating can be reliably performed by the individual heaters 60. In addition, since the drive motor 58 and the heater 60 are disposed in the dryer body 11, all necessary wiring can be disposed in the dryer body 11. Therefore, the number of parts can be reduced and the entire size can be reduced, and disconnection and the like can be prevented from being caused by the rotation at the hinge connecting portion 20. Furthermore, since the branch passage 49 that constitutes a part of the internal air passage 38 is provided in the hinge connection portion 20, the internal air passage 38 can be bent without providing additional parts. Further, it is possible to form a cylindrical internal air passage 38 in which the air flow is most efficient.

  When using the futon dryer 10 equipped with this blower, as shown in FIG. 5 and FIG. 6, it is in a state in which the discharge member 26 is expanded so as to be positioned on the lateral side with respect to the dryer body 11. . In this state, for example, after arranging on the mattress so that the suction part 15 is located at the position where the pillow is placed, the comforter is set on the mattress.

  At this time, in this embodiment, the overall height of the suction portion 15 is made higher than the overall height of the discharge member 26 and the step portion 16 is provided. Therefore, by positioning the end of the comforter on the step portion 16, the suction portion 15 is placed on the comforter. Can be reliably exposed to the outside. Moreover, since the discharge member 26 is in a state of being extended so as to be positioned on the side with respect to the dryer main body 11, the discharge member 26 protrudes from the suction portion 15 with a sufficient dimension. Insertion and placement can be ensured. Furthermore, in this state, since the inclined portions 14a and 32 are provided on both sides of the overlapping portion 14 and the discharge member 26, a gap formed between the mattress and the comforter can be eliminated. In addition, since the blades 57A and 57B and the drive motor 58 are collectively disposed in the suction portion 15, the overall height of the discharge member 26 can be reduced. Also from this configuration, a gap formed between the comforter and the comforter can be eliminated.

  And if a drying process is performed by a user's operation, the drive motor 58 and the heater 60 will be operated. As a result, as shown in FIG. 4, outside air is sucked from the suction ports 17A and 17B on both sides of the suction portion 15, and the outside air flows into the first inner passages 39A and 39B from the pair of inflow ports 41a and 41b. Thereafter, the air flows into the second internal passage 43 from the pair of first internal passages 39 </ b> A and 39 </ b> B, and is heated by the heater 60 in the second internal passage 43. Then, the air is diverted again in the branch passage 49, flows into the pair of third internal passages 50A and 50B, and is discharged between the futons through the discharge ports 36A and 36B.

  At this time, in the present embodiment, the suction part 15 can be reliably exposed to the outside of the comforter by the step part 16, so that the suction ports 17A and 17B formed in the suction part 15 are not blocked by the comforter. Further, since the suction ports 17A and 17B are provided on both side surfaces of the suction portion 15, the suction ports 17A and 17B are not blocked even when used on a bed having a wall at the head. Further, in the first internal passages 39A and 39B, since the outside air can be taken in from both sides of the blades 57A and 57B, an efficient air volume can be obtained. Furthermore, since the outside air sucked from the pair of suction ports 17A and 17B is partitioned by the first internal passages 39A and 39B and is obliquely merged in the second internal passages 43, loss due to collision with each other is eliminated. Can do. In addition, the overall height of the discharge member 26 can be reduced, and the configuration provided with the inclined portions 14a and 32 can eliminate the gap between the comforter and can reliably obtain a desired air volume. Therefore, it is possible to reliably blow the warm air to the feet without escaping the warm air, which is efficient.

  Further, a sufficient air volume can be obtained by disposing the blades 57A and 57B at the suction ports 17A and 17B, and the discharge member 26 has a horizontally long flat shape, and two or more discharge ports 36A on both sides thereof. , 36B, and third internal passages 50A, 50B are provided so as to communicate with the discharge ports 36A, 36B. Therefore, the range that can be discharged from the discharge ports 36 </ b> A and 36 </ b> B can be efficiently widened, and the bias of the blown air amount can be prevented and efficient air blowing can be performed. As a result, warm air can be reliably distributed over the entire surface between both futons. Moreover, since the internal air passage 38 is provided so as to face the bottom walls 12a and 27a so that the heat of the warm air heated by the heater 60 is transmitted to the mattress, the placement of the futon dryer 10 in the mattress is placed. Parts can also be warmed and dried. Moreover, the part covered with the comforter through the top wall 14b and the recessed part 33 can also be warmed and dried.

  On the other hand, the warm air discharged between the mattress and the comforter flows into the external inflow portion 51 having a low fluid resistance when a large gap is not formed on the outer periphery of the comforter. And since the opening part 51a (entrance / exit) of this external inflow part 51 is provided in the discharge member 26 side from the suction part 15, it passes through the 2nd external path 55 from the 1st external path 52, or 2nd From the external passage 55, the first external passage 52 is circulated and discharged between the mattress and the comforter. That is, the warm air discharged from the discharge ports 36A and 36B will not escape to the outside. As a result, the placement portion of the futon dryer 10 in the mattress can also be effectively warmed and dried by the warm air discharged from the discharge ports 36A and 36B. Moreover, in the present embodiment, since the first external passage 52 is provided between the pair of third internal passages 50A and 50B, the entire lower surface of the discharge member 26 in the mattress can be reliably dried.

  Thus, in this embodiment, since the discharge member 26 is arrange | positioned between a mattress and a comforter, and the heated warm air is discharged, it is not necessary to use an air mat. Therefore, the number of parts can be reduced and usability can be improved.

Yes. Further, a pair of second external inflow portions 51B and 51B are provided in the overlapping portion 14 of the dryer main body 11 so as to be positioned on both sides of the second internal passage 43 (heater case 44). The openings 51a of the external inflow portions 51A and 51B are located closer to the discharge member 26 than the suction portion 15, and the external inflow portions 51A and 51B are located at portions other than the top surface projection surface of the internal air passage 38.

  In the futon dryer 10 of the second embodiment configured as described above, similarly to the first embodiment, the heater 60 is disposed through the bottom walls 12a and 27a in the area located below the internal air passage 38 in the mattress. Warm and dry with warm air heated in Further, the region that cannot be warmed and dried via the bottom walls 12a and 27a can be warmed and dried by the warm air that has entered the external inflow portions 51A and 51B. As a result, the entire placement portion of the futon dryer 10 in the mattress can be effectively warmed and dried.

  In addition, the futon dryer 10 of this invention is not limited to the structure of the said embodiment, A various change is possible.

  For example, in the above-described embodiment, the first external passage 52 or the first external inflow portion 51A is positioned between the pair of third internal passages 50A and 50B, but the pair of first internal passages on both sides of one third internal passage. It is good also as a structure which arrange | positions an external channel | path or an external inflow part. Moreover, although the external inflow part 51 was formed also in the superimposition part 14 of the dryer main body 11, it is good also as a structure provided only in the discharge member 26 like the 1st external inflow part 51A of 2nd Embodiment.

  Further, in the first embodiment, the superimposing portion 14 is configured such that a part of the external inflow portion 51 is positioned so as to overlap the second internal passage 43 of the internal air passage 38 in the vertical direction. The passage 55 may be branched so that the third internal passages 50A and 50B partially overlap with each other. Further, in each of the above embodiments, the external inflow portions 51, 51 </ b> A, 51 </ b> B are provided so as to be positioned closer to the discharge member 26 than the suction portion 15, but, for example, the first external passage 52 extends to the back surface 15 a of the suction portion 15. It may be provided through. Further, as shown in FIG. 9, in the external inflow portion 51, only the external passages 55A and 55B in which the openings 51a are formed so as to be located on both sides are provided so as to be located on the discharge member 26 side from the suction portion 15, The continuous portion 55C that continues the external passages 55A and 55B may be provided so as to be positioned on the suction portion 15 side.

  Furthermore, in the said embodiment, although the discharge member 26 which comprises a discharge part was rotatably arrange | positioned with respect to the dryer main body 11, it is good also as a structure which cannot be rotated by providing the discharge member 26 integrally. Furthermore, in the above-described embodiment, the suction ports 17A and 17B are provided on both sides of the suction portion 15. However, the suction ports 17A and 17B may be provided only on one side surface, and a suction port is provided on the top surface and the back surface 15a other than the side surface. May be.
