It may be formed.

  The reinforcing case 68 has a rectangular tube shape, and is disposed in the heater case 46 so that all air passing through the second passage 45 passes through the inside. The reinforcing case 68 is made of metal, and constitutes a reinforcing portion that increases the pressure resistance between the upper and lower walls 13 a and 12 a of the heating region 16 from the upstream side to the downstream side of the PTC heater 55 in the overlapping portion 14. The reinforcing case 68 is screwed to the bottom plate portion 69 disposed on the bottom wall 47a of the heater case 46, the side plate portions 70a and 70b erected from both sides of the bottom plate portion 69, and the upper ends of the side plate portions 70a and 70b. And a separate top plate portion 71. The total height of the side plate portions 70 a and 70 b is set so that the top plate portion 71 is close to the top wall 48 a of the heater case 46. The side plate portion 70a is provided with a groove-like insertion portion 72 that exposes the connection terminal 56 to the outside. In the rectangular openings 68a at both ends of the reinforcing case 68, separate support pillars 73 having a trapezoidal shape are disposed. The support column portion 73 is located on the upstream side and the downstream side of the PTC heater 55 in the heating region 16 and constitutes a reinforcing portion that further increases the pressure strength between the upper and lower walls 13a and 12a.

  Inside the reinforcing case 69, a thermistor 74 and thermal fuses 75A and 75B are disposed as a safety device for preventing overheating by the PTC heater 55. The thermistor 74 is disposed on the top wall 48 a of the third upper case 48 of the heater case 46 of the reinforcing case 69. The detection unit 74 a of the thermistor 74 passes through the top wall 48 a and the top plate part 71, is positioned in the reinforcing case 69, and detects the heating temperature by the PTC heater 55. The thermal fuses 75A and 75B are connected in series, and one thermal fuse 75A is disposed on the support column portion 73 located on the upstream side, and the other temperature fuse 75B is disposed on the support column portion 73 located on the downstream side. ing. That is, the thermistor 74 is disposed so that only the detection portion 74 a is located in the reinforcing case 67, and the thermal fuses 75 </ b> A and 75 </ b> B are disposed so as to be entirely located in the reinforcing case 67.

  When using the futon dryer 10, as shown in FIG. 1 and FIG. 2, the discharge member 27 is spread so as to be located on the lateral side with respect to the dryer body 11, and the bottom wall 12a of the dryer body 11 and The bottom wall 28a of the discharge member 27 is flush with the surface. In this state, for example, after arranging on the mattress so that the suction part 17 is located at the position where the pillow is placed, the comforter is set on the mattress. At this time, the suction portion 17 can be reliably exposed to the outside of the comforter by positioning the end of the comforter on the step portion 18. As a result, it is possible to prevent erroneous use of closing the suction port 19 formed in the suction portion 17.

  When the drying process is executed by a user operation, the drive motor 54 and the PTC heater 55 are operated. As a result, as shown in FIG. 5, outside air is sucked from the suction ports 19 on both sides of the suction portion 17, and the outside air flows into the first passage 41 from the pair of inflow ports 43 and 43. Thereafter, the air flows into the second passage 45 from the pair of first passages 41, and the air is heated by the PTC heater 55 through the heat transfer cases 57 </ b> A and 57 </ b> B in the second passage 45. At this time, since the heat transfer cases 57A and 57B are integrally provided with a large number of heat radiation fins 58A and 58B, the heat of the PTC heater 55 is surely transferred and the sucked outside air is heated (heated up). Can do. Then, the heated air is diverted again in the third passage 49 and flows into the fourth passage 52, and is discharged from both the futons from the discharge port 36.

  In this use state, since the comforter is put on the overlapping portion 14 and the discharge member 27 which are the insertion portions, there is a possibility that the user or the family steps inadvertently. However, in the present embodiment, the reinforcing case 68 is disposed in the heating region 16 extending from the upstream side to the downstream side of the PTC heater 55 to increase the vertical pressure strength. Therefore, it is possible to prevent the heating area 16 from being damaged when it is stepped on carelessly. As a result, excessive unintentional heat generation by the PTC heater 55 can be prevented, and the safety of the product can be improved. Further, since the reinforcing case 68 is made of a rectangular cylindrical member close to the bottom wall 12a and the top wall 13a of the overlapping portion 14, a sufficient strength is ensured after ensuring a sufficient cross-sectional area as the air passage 40. it can.

  Furthermore, since the detection portion 74a of the thermistor 74 and the temperature fuses 75A and 75B are disposed in the reinforcing case 68 of the present embodiment, damage when inadvertently stepped on can be prevented. Moreover, since the inside of the reinforcing case 68 is a portion that does not deform even when an external force is applied, the temperature fuses 75A and 75B, which are disposed entirely inside the reinforcing case 68, can fix the detection position accurately. Therefore, since the heating temperature can be accurately detected, the safety and reliability of the product can be improved.

  Furthermore, the PCT heater is accommodated in metal heat transfer cases 57A and 57B. A gap between the heat transfer cases 57A and 57B is sealed by a seal member 62. Therefore, oil can be reliably prevented from adhering to the PTC heater 55. In addition, since the heat-resistant members 63A and 63B for mounting are arranged at both ends of the heat transfer cases 57A and 57B, even if the oil component enters and the PTC heater 55 goes out of control, the molten element remains in the heat transfer case 57A. , 57B can be prevented from diffusing. Therefore, also from this point, the safety and reliability of the product can be improved. Further, the strength in the heating region 16 can be further improved by the mounting heat-resistant members 63A and 63B.

  In addition, in the present embodiment, the discharge member 27 that is pivotably hinged is provided, the hinge connecting portion 22 is provided in the vicinity of the heating region 16, and the reinforcing rings 26 are disposed at both ends of the hinge connecting portion 22. Therefore, the strength of the heating region 16 can be further increased. Moreover, since the discharge member 27 is configured to be rotatable with respect to the dryer main body 11 by the hinge connection portion 22, when not in use, as shown in FIGS. 3 and 4, it can be compactly folded and stored. it can.

  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, although the PTC heater 55 is used in the above embodiment, the heating means may be constituted by a mica heater wound with a nichrome wire. Further, the reinforcing case 68 is not limited to a rectangular tube shape (rectangular shape) having both ends opened, and may be an octagonal tube shape having chamfered walls at corners. In other words, the rectangular shape includes not only the rectangle itself but also a shape close to the rectangle, and includes a rectangular shape formed by arranging square reinforcing members as a whole. Moreover, it is good also as an elliptic cylinder shape or a true cylinder shape. Furthermore, although the reinforcement part 68 of the separate body was used for the reinforcement part, you may provide a reinforcement rib and the boss | hub for reinforcement in the part of the upstream of the heating area | region 16 of the heater case 46, and a downstream part.
