JP 2002-253388 A (page 1 to page 3, FIGS. 1, 4, 7, and 12) Japanese Patent Application Laid-Open No. 61-220617 (page 3, FIG. 6) JP-A-11-299582 (first page, fourth page, fifth page, FIGS. 7 and 8)

In the prior art shown in Patent Document 1, an air blowing plate is installed under the mattress, and the mattress is dried and heated by blowing warm air from a plurality of openings provided on the air blowing plate. Therefore, the temperature on the lower surface side of the mattress is higher than that on the upper surface side, resulting in a temperature difference. In other words, for the sleeping person, there is a fear that the temperature of the upper surface of the mattress that the body directly contacts is not satisfactory. Moreover, in the prior art shown in patent document 1, since it is not what dries and heats directly from the inside of a mattress, but is dried and heated indirectly from the lower side of a mattress, it is laid on a ventilation plate. When the thickness of the mattress is large, it takes time to dry and heat the entire mattress, and there is a risk that the hot air generator and the blower may be burdened.
On the other hand, the prior art shown in Patent Document 2 has a configuration in which warm air or the like is blown into an air circulation passage embedded in a mattress-shaped body, and the mattress is dried from the interior of the mattress body. -Since it can heat, the problem of the prior art shown in the patent document 1 mentioned above can be eliminated.
However, in the prior art shown in Patent Document 2, a single circulation passage is arranged in the mattress body, and the circulation passage is configured to blow and supply only warm air if hot air and only cold air if cold air. For example, it was not possible to circulate cool air on the upper body side of the mattress and hot air on the lower body side of the mattress. This is also true for the prior art shown in Patent Document 1, that is, in the prior art shown in Patent Document 1 and Patent Document 2, the arrangement of the opening of the air blowing plate and the circulation passage is the upper half of the mattress, respectively. It is not a configuration that is divided into a side and a lower body side, and it does not have a configuration that feeds air having different temperatures to the upper body side and the lower body side of the mattress.
On the other hand, in the prior art shown in Patent Document 3, since the first air circulation unit and the second air circulation unit are arranged separately in the mattress, the first air circulation unit is disposed on the head side of the mattress. It is possible to heat the foot side with a warm air of a high temperature by the second air circulation unit.
However, in the prior art shown in Patent Document 3, the first air circulation unit and the second air circulation unit are respectively provided with a hot air / cold air supply unit via a hot air supply tube and a hot air return tube provided independently of each other. The so-called circulation system connected to the motor requires various devices such as motors, air pumps, heaters, Peltier temperature control units with Peltier temperature control elements, switching valves, etc. It has a complicated structure. For this reason, the manufacturing cost is high, and maintenance of various devices is also troublesome. The same problem is also true for the prior art shown in Patent Document 2 that employs a circulation system. In the prior art shown in Patent Document 2, a compressor or a circulation system for pumping air into the circulation passage is also available. A device such as a throttle valve for adjusting the pressure in the passage is required, and the structure has a large number of devices.
Furthermore, in the prior art employing the circulation method shown in Patent Document 2 and Patent Document 3, the air flow passage through which air such as hot air and cold air is blown is not provided with an opening through which air is blown. From the viewpoint of drying and dehumidifying, the drying and dehumidifying efficiency is poor compared to the prior art disclosed in Patent Document 1.
On the other hand, in the prior arts shown in Patent Literature 2 and Patent Literature 3, the mattress body does not have a folding structure, and therefore, it is inconvenient for folding the mattress and storing it in a closet or the like.

Since it is formed, it is difficult to hold the mattress body in a folded state, as in the prior art disclosed in Patent Document 2. For example, the conventional technique shown in FIG. 6 of Patent Document 1 discloses a foldable blower plate. In this case, air flow such as a pipe through which air such as warm air is blown is supplied to the blower plate. The road is not arranged, and is particularly limited to the one provided with an air opening for blowing warm air or the like at the upper part thereof.

  Also, rigid joint portions 38 and 40 are connected to one end side and the other end side in the longitudinal direction of the other second pipe line 28b, respectively. The joint portion 38 includes, for example, an elbow as a rigid pipe joint. One end side in the longitudinal direction of the second pipe line 28b is connected to one side of the two connection ports of the elbow. The other end side in the longitudinal direction of one second flexible tube 30 of the second conduit 28b is connected to one connection port of the elbow. The other end side in the longitudinal direction of the first pipe line 18a is connected to the other connection port of the elbow. In this case, the 1st rigid pipe | tube 20 of the 1st pipe line 18a is connected to the other connection port of this elbow.

  Further, the joint portion 40 includes, for example, T (tee) as a rigid pipe joint. The other end side in the longitudinal direction of the second conduit 28b is connected to a connection port in a direction perpendicular to the longitudinal direction of the T (tee). The other end in the longitudinal direction of the other second flexible tube 30 of the second conduit 28b is connected to a connection port in a direction perpendicular to the longitudinal direction of the T (tee). The other end side in the longitudinal direction of the first pipe line 18c is connected to one of the two connection ports of the T (tee) that are linearly opposed. In this case, the 1st rigid pipe | tube 20 of the 1st pipe line 18c is connected to one connection port which this T (tee) opposes linearly. The other connecting port of the T (tee) that is linearly opposed is arranged facing the outside of the mattress body 12 through the groove 14A, and can communicate with the outside.

The first flexible tube 22 and the second flexible tube 30 are particularly easy to bend using, for example, a bellows hose, considering the difference in expansion / contraction ratio between the inner surface side and the outer surface side of the flexible tube. Therefore, it is preferable. That is, when the first flexible tube 22 and the second flexible tube 30 have a large difference in expansion / contraction rate, for example, a rubber hose is used, the first flexible tube 22 and the second flexible tube 22 This is because the flexibility for bending displacement when the flexible tube 30 is bent is low, and it is difficult to bend compared to the bellows hose.

  As shown in FIG. 3, the other air transfer path 16 </ b> B includes the one air transfer path 16 </ b> A described above and a line indicated by a two-dot chain line extending vertically in the center in the longitudinal direction of the mattress body 12 and in the width direction thereof. When the reference line w-w is used, the line is symmetrical with respect to the reference line w-w. That is, one air transfer path 16A and the other air transfer path 16B are respectively connected to the three first pipe lines 18a, 18b, and 18c and the two joint parts 34, 36, 38, and 40, respectively. The first pipes 18a to 18c include two first rigid pipes 20 and one first flexible pipe 22, and the second pipes 28a and 28b. 28a and 28b have a piping structure including two second flexible pipes 30 and a joint part 32 having rigidity.

One piping unit is constituted by the piping line and the introduction pipe line. In the present embodiment, two air transfer paths 16A and 16B arranged at intervals in the longitudinal direction of the mattress body 12 are each formed by one piping unit. Each piping unit is arranged, for example, in a B shape in plan view when viewed in the longitudinal direction of the mattress body 12. The two piping units are spaced in the longitudinal direction of the mattress body 12 so that one air transfer path 16A is arranged on the upper body side of the user (sleeping person) and the other air transfer path 16B is arranged on the lower body side. They are spaced apart.

The air transfer paths 16A and 16B described above are positioned and supported on the mattress body 12 by the grooves 14A and 14B, respectively. In this case, the lower portions of the air transfer paths 16A and 16B are fitted and accommodated in the grooves 14A and 14B.
Further, as shown in FIG. 2, the upper surface of the mattress body 12 is covered with a pressing portion 46 having a rectangular shape in plan view so as to cover the grooves 14A and 14B. The pressing portion 46 is formed to have substantially the same size as the planar shape of the mattress body 12. The pressing portion 46 is formed of a breathable batting and is fixed to the upper surface of the mattress body 12 by fixing means (not shown) such as an adhesive. Therefore, the air transfer paths 16A and 16B fitted into the groove portions 14A and 14B of the mattress body 12 are not displaced by the cooperative action of the groove portions 14A and 14B and the pressing portion 46, and the desired position of the mattress body 12 is obtained. Can be fixed stably. The pressing portion 46 is made of synthetic fiber such as polyethylene subjected to antibacterial and deodorizing processing, for example. Further, the pressing portion 46 can be formed of compressed cotton formed by a method such as punching with a needle by mechanically pressing and compressing a synthetic resin fiber such as felt-like polyester with a pressing roller or the like.

  Furthermore, the mattress body 12, the air transfer paths 16A and 16B supported by the grooves 14A and 14B, and the pressing portion 46 are encapsulated by a cover side ground 48 having air permeability. The cover side ground 48 is formed in a bag shape with synthetic fibers such as polyethylene. In this case, the bag-like cover side ground 48 has an opening (not shown) on one side in the width direction, and a fastener portion 50 is provided to open and close the opening. The mattress body 12, the air transfer paths 16 </ b> A and 16 </ b> B, and the pressing portion 46 can be freely inserted into and removed from the cover side ground 48 by opening and closing the fastener portion 50. Thus, the mattress 10 including the air transfer paths 16A and 16B is configured.

  In the mattress 10 according to the above-described embodiment, in particular, as shown in FIG. 3, the air from the blower F is separately provided via the transfer pipe 44, the introduction pipe 42, and the joint portion 40, respectively. It is transferred and supplied to the two air transfer paths 16A and 16B. The blower F is provided with a timer or the like, and the temperature of the entire mattress 10 can be controlled by intermittently operating the blower F. Therefore, for example, it is not necessary to change the magnitude of the heat amount of the heat source generator or to accompany an automatic temperature controller such as a thermostat.

  In general, an automatic temperature control device such as a thermostat is disposed inside or in the vicinity of the heat source generator, and in particular, there are many that monitor and suppress the temperature rise (humidity rise) of the mattress 10. In this case, however, the thermostat or the like can only partially monitor the mattress in the vicinity of and around the heat source generator.
