Therefore, the current in the blower pipe 1 is not in the length direction,
It will flow in the circumferential direction. As the conductive material, any material that generates heat when energized can be used as in the embodiment of FIG. 6, and a heat-generating conductive resin in which conductive fine particles are mixed into a resin is used. Thereby, it can function as a thermostat.

This example is an example in which the density of the blower pipes 1 is unevenly arranged. For example, the number of turns of the blower pipe 1 closer to the blower 7 is increased to increase the density of the blower pipe 1, and the number of turns of the blower pipe 1 farther from the blower 7 is reduced to lower the density of the blower pipe 1. can do.

For example, the blow holes 2 of the blow pipe 1 closer to the blow device 7 are densely provided, and the blow holes 2 of the blow pipe 1 far from the blow device 7 are coarsely provided. By providing the outlets 2 unevenly in this way, the temperature can be changed depending on the location of the bedding 6 as in the case of FIG.

And the pitch P2 of the resistance wires 8 of the blower pipe 1 farther from the blower 7 is made coarser. Thus, the resistance wire 8
By providing the pitches unevenly, the temperature can be changed depending on the location of the bedding 6 as in the case of FIG. In FIG. 10, the blowout holes 2 of the blower pipe 1 are not shown.

FIG. 11 is a schematic plan view of a blower pipe for explaining another example of the shape of the blower pipe 1 in each embodiment described above. The blower pipe 1 includes a large-diameter portion 1A and a small-diameter portion 1B that communicate with each other.
The large-diameter portion 1A connected to the left and right sides is divided into left and right side surfaces.

It is possible to heat substantially uniformly over the entire length of the pipe.

(2) On the other hand, the arrangement of the blowing pipe,
It is possible to arbitrarily set the temperature distribution according to the position of the bedding by devising the winding method of the resistance wire, the arrangement of the blowing holes or the size of the diameter.

(3) Since the heat-generating member is provided along the length of the blower pipe, humidified air can be sent into the blower pipe, and water droplets can be easily removed even if the blower pipe forms dew. The same applies to the case where the blower pipe itself is formed of a conductive material. Further, it is possible to easily prevent dew condensation by continuing to supply current to the heat generating member or the conductive blower pipe for a certain period of time after stopping humidification after getting up. Furthermore, the amount of dew condensation is small because the amount of air in the blower pipe is smaller than that of a conventional example in which a blower is connected to an air passage in an air mattress.
