Summary of the Invention

Problems to be Solved by the Invention

[0004] As a mattress, not only the function of simply supporting the user at bedtime but also, for example, the function of promoting the user's health is being considered.

[0005] One object of the present invention is to provide a far-infrared warm water mattress device capable of promoting the health of the user.

Means for Solving the Problems

[0006] The far-infrared warm water mattress device according to the present invention includes a mattress body, a flow path through which warm water for warming the mattress body flows, and a warm water supply unit that is disposed outside the mattress body and supplies warm water to the flow path. The mattress body has a first mattress core material having thermal conductivity and a second mattress core material that is disposed on the first mattress core material and includes a plurality of far-infrared radiators. A part of the flow path is disposed in the mattress body in contact with the first mattress core material.

[0007] In the above configuration, hot water flows through the channel by the hot water supply unit. Part of the channel is positioned in contact with a first mattress core material that has thermal conductivity within the mattress body. In this configuration, the first mattress core material is heated by the hot water, so the user of the mattress body is also heated. A second mattress core material containing multiple far-infrared radiators is placed on the first mattress core material. Therefore, when the first mattress core material is heated, far-infrared rays are emitted from the multiple far-infrared radiators of the second mattress core material. The user is also heated by these far-infrared rays. In this way, the far-infrared hot water mattress device heats the user with hot water and far-infrared rays, so for example, the user's blood circulation can be improved, and the user's health can be promoted.

[0008] A portion of the above-mentioned flow path may meander when the mattress body is viewed from the thickness direction. This makes it possible to warm a wider area of ​​the user's body.

[0009] The above far-infrared radiator is sericite It may also be a tile formed by [a specific method]. sericite It is known to have a high far-infrared radiation capacity. Therefore, it can warm the user even more effectively.

[0010] The mattress further comprises a cushion member placed on the second mattress core, the second mattress core being provided on the first mattress core and having a support sheet for supporting the plurality of far-infrared radiators, and the plurality of far-infrared radiators may be provided on the cushion member side relative to the support sheet.

[0011] In the above configuration, multiple far-infrared radiators are arranged on a support sheet. In this case, the second mattress core material has irregularities on the side opposite to the first mattress core material. Even if irregularities are formed on the second mattress core material in this way, the mattress body has the cushioning member, so the effect of the irregularities can be mitigated by the cushioning member.

[0012] The mattress body described above may have a surface fabric containing terahertz wave emitters. The terahertz waves emitted from the terahertz wave emitters enhance the thermal energy of the human body. As a result, the user becomes even warmer.

[0013] The mattress body may further have a heat-conducting sheet having higher thermal conductivity than the first mattress core material on the side opposite to the first mattress core material when viewed from the second mattress core material. In this case, heat is easily transferred to the entire mattress body when viewed from the thickness direction of the mattress body.

[0014] The mattress body described above may have at least one of the following properties: heat insulation and far-infrared reflection, on the side opposite to the second mattress core material when viewed from the first mattress core material. This makes it easier to warm the user, for example.

[0015] The mattress further comprises a mattress cover that accommodates the mattress body, and the mattress cover may contain far-infrared radiating material. Since the mattress cover can also emit far-infrared rays, the warming effect by far-infrared rays can be enhanced. [Effects of the Invention]

[0016] According to one aspect of the present invention, it is possible to provide a far-infrared hot water mattress device that can promote the health of the user. [Brief explanation of the drawing]

Best Mode for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The same or corresponding parts in the drawings are denoted by the same reference numerals, and redundant descriptions are omitted. The dimensional ratios in the drawings do not necessarily match those in the description.

[0019] FIG. 1 is a schematic diagram for explaining the configuration of a far-infrared hot water mattress device 10 according to an embodiment. As shown in FIG. 1, the far-infrared hot water mattress device 10 includes a mattress body 12, a hose 14 (flow path), and a hot water supply unit 16. In the far-infrared hot water mattress device 10, hot water 20 (see FIG. 2) is flowed through the hose 14 to warm the mattress body 12. As a result, the user of the mattress body 12 is warmed.

[0020] The mattress body 12 in the present embodiment is a mattress that a user uses, for example, when going to bed, unless otherwise stated. Therefore, the planar shape of the mattress body 12 is rectangular. The size of the mattress body 12 may be a size known in the field of mattresses. The length of the mattress body 12 in the longitudinal direction is, for example, 100 cm to 300 cm, and the length in the width direction (the direction perpendicular to the longitudinal direction) is, for example, 50 cm to 300 cm. In one example, the length of the mattress body 12 in the longitudinal direction is 200 cm, and the length in the width direction is 100 cm.

[0021] The hose 14 is a flow path through which the hot water 20 flows. The temperature of the hot water 20 is, for example, 30°C to 70°C. The hose 14 has heat resistance that allows the hot water 20 to flow through it. A part of the hose 14 is disposed inside the mattress body 12. Hereinafter, for convenience of explanation, the part of the hose 14 disposed inside the mattress body 12 is referred to as an inner hose portion 22, and the part disposed outside the mattress body 12 is referred to as an outer hose portion 24.

[0022] The inner hose section 22 is positioned to warm the entire predetermined region A (the region indicated by the dashed line) when the mattress body 12 is viewed from above (viewed from the thickness direction). For example, the inner hose section 22 meanders (or bends multiple times) within the predetermined region A. For example, the inner hose section 22 has multiple straight regions 22a and multiple U-shaped regions 22b. The multiple straight regions 22a are arranged in parallel. Each U-shaped region 22b is a region that connects the ends of adjacent straight regions 22a. The inner hose section 22 may also be arranged in a bellows-like manner within the predetermined region A. The predetermined region A is, for example, the region where the user's torso and legs are assumed to be located when the user lies on the mattress body 12. The predetermined region A may be, for example, a region of 20% or more of the area of ​​the mattress body 12 when viewed from above. The predetermined area A may be, for example, 50% or 60% or more of the area of ​​the mattress body 12 when viewed from above. The predetermined area A may be 100% or less, but may also be 90% or less, or 80% or less. If the mattress body 12 has a size of 100cm x 200cm, the predetermined area A may be, for example, 80cm x 150cm. The outer hose section 24 is connected to the hot water supply section 16.

[0023] The hot water supply unit 16 flows hot water 20 at a constant temperature into the hose 14. The hot water supply unit 16 may be a device for operating the far-infrared hot water mattress device 10. In this embodiment, the hot water supply unit 16 is a small boiler (or water heater). That is, it heats the water supplied to the hot water supply unit 16 to produce hot water 20. The hot water supply unit 16 flows the produced hot water 20 into the hose 14. The hot water supply unit 16 only needs to be configured to be able to flow hot water 20 at a constant temperature into the hose 14.

[0024] An example of a hot water supply unit 16 will be explained using Figures 1 and 2. Figure 2 is a schematic diagram illustrating the configuration of an example of a hot water supply unit 16. In Figure 2, the housing of the hot water supply unit 16 is not shown.

[0025] In one embodiment, the hot water supply unit 16 includes a housing 26, a storage unit 28, a pair of pipes 30a and 30b, a pump 32, a temperature sensor 34, a heater (temperature control unit) 36, an operating unit 38, and a control unit 40.

[0026] The housing 26 houses the storage unit 28. The housing 26 is configured to allow a hose 14 to be connected to the storage unit 28 and to supply hot water 20 or water to the storage unit 28.

[0027] The storage section 28 is the part that stores hot water 20. The hot water 20 in the storage section 28 is hot water 20 obtained by heating water after it has been supplied to the storage section 28. However, the hot water 20 may be supplied directly to the storage section 28. The storage section 28 has a supply port 28a from which water (or hot water 20) is supplied from outside the hot water supply section 16, and the supply port 28a can be opened and closed by a lid 42 (see Figure 1). The capacity of the storage section 28 is, for example, 1.2 L (liters) to 3 L. In one embodiment, the capacity of the storage section 28 is 1.5 L.

[0028] A pair of pipes 30a and 30b for connecting a hose 14 are connected to the storage section 28. One end of the hose 14 is connected to pipe 30a, and the other end of the hose 14 is connected to pipe 30b. The hose 14 can be detachably connected to pipes 30a and 30b. The method of connecting pipes 30a and 30b to the hose 14 is not limited as long as the connection can be made without leakage of hot water 20. A circulation path for hot water 20 is formed by connecting the storage section 28 and the hose 14 via pipes 30a and 30b.

[0029] Pump 32 is attached to piping 30a. Pump 32 is a machine for supplying hot water 20 to hose 14. Pump 32 may be electrically driven. Pump 32 may also be attached to piping 30b.

[0030] The heater 36 heats the water supplied to the storage unit 28 to produce hot water 20. The heater 36 also has the function of maintaining the temperature of the hot water 20 at a predetermined temperature (the temperature received by the input unit described later).

[0031] The temperature sensor 34 measures the temperature of the hot water 20. The installation location of the temperature sensor 34 is not limited as long as it can measure the temperature of the hot water 20. The temperature sensor 34 can be, for example, a sensor used in a household water heater or boiler.

[0032] The operation unit 38 has an input unit 38a and a display unit 38b. The input unit 38a is the part that receives operation information from the user for the far-infrared hot water mattress device 10. The operation information includes ON / OFF information for the far-infrared hot water mattress device 10. The operation information may also include timer information that specifies the usage time of the far-infrared hot water mattress device 10. The operation information may also include temperature information (specified temperature) of the hot water 20 in the far-infrared hot water mattress device 10. The input unit 38a may be provided on the outer surface of the housing 26. The input unit 38a may include, for example, a button, a switch, etc.

[0033] The display unit 38b is a part that displays the operating status of the far-infrared hot water mattress device 10. For example, the display unit 38b displays whether the far-infrared hot water mattress device 10 is ON or OFF. If the timer sets the reservation time (start time), usage time, etc. for the far-infrared hot water mattress device 10, the display unit 38b may display the remaining operating time of the far-infrared hot water mattress device 10, the remaining usage time, etc. If the user specifies the temperature of the hot water 20, the display unit 38b may display the temperature entered by the user, the actual temperature of the hot water 20, etc.

[0034] The control unit 38 may be, for example, a touch panel type control unit.

[0035] The control unit 40 controls the hot water supply unit 16. For example, the control unit 40 controls the heater 36 to adjust the temperature of the hot water 20 so that it reaches a preset temperature or a temperature received by the input unit 38a. In this case, the control unit 40 provides feedback control to the heater 36 based on the measurement result of the temperature sensor 34, for example. The control unit 40 may also display the measurement result of the temperature sensor 34 on the display unit 38b. When the temperature of the hot water 20 is the specified temperature, the control unit 40 drives the pump 32 to supply the hot water 20 into the hose 14.

[0036] Figure 3 is an exploded view showing an example of a mattress body 12. The mattress body 12 has a first mattress core material 48 and a second mattress core material 50. The mattress body 12 may further have at least one of a bottom fabric 44, an insulating sheet 46, a cushioning member 52, a heat conductive sheet 54, and an outer fabric 56. In the following, unless otherwise specified, a mattress body 12 having a bottom fabric 44, an insulating sheet 46, a cushioning member 52, a heat conductive sheet 54, and an outer fabric 56 will be described.

[0037] The insulation sheet 46, the first mattress core material 48, the second mattress core material 50, the cushioning member 52, the heat conductive sheet 54, and the top fabric 56 are laminated on the bottom fabric 44 in this order. The plan view shapes of the bottom fabric 44, insulation sheet 46, first mattress core material 48, second mattress core material 50, cushioning member 52, and heat conductive sheet 54 are the same as the plan view shape of the mattress body 12, and in this embodiment, they are rectangular. The top fabric 56 can be joined to the bottom fabric 44, for example, while covering the laminate formed by the insulation sheet 46, first mattress core material 48, second mattress core material 50, cushioning member 52, and heat conductive sheet 54. For example, the top fabric 56 and the bottom fabric 44 may be joined by sewing them together. Alternatively, the mattress body 12 may further include a peripheral fabric that covers the periphery of the bottom fabric 44 and the top fabric 56, and the peripheral fabric may be joined to the bottom fabric 44 and the top fabric 56. In this case as well, the perimeter fabric may be sewn to the bottom fabric 44 and the outer fabric 56.

[0038] The bottom fabric 44 is positioned on the bottom side (for example, the floor side) of the mattress body 12. The bottom fabric 44 may have an anti-slip function. Examples of materials for the bottom fabric 44 include polyvinyl chloride (PVC), polyester, and nylon. The thickness of the bottom fabric 44 is, for example, 0.5 mm to 2 mm. In one embodiment, the thickness of the bottom fabric 44 is 1 mm.

[0039] The insulation sheet 46 is placed on the bottom fabric 44. The insulation sheet 46 is a sheet that prevents the temperature of the mattress body 12 from dropping due to, for example, the floor on which the mattress body 12 is placed. The insulation sheet 46 may be flexible. Examples of materials for the insulation sheet 46 include polyurethane, PVC, and aluminum foil. The thickness of the insulation sheet 46 is, for example, 0.5 mm to 2 mm. In one embodiment, the thickness of the insulation sheet 46 is 2 mm.

[0040] The first mattress core material 48 is placed on the insulation sheet 46. The first mattress core material 48 supports the hose 14. The hose 14 is supported by the first mattress core material 48 so that hot water 20 can flow through the hose 14 even when the user is using the mattress body 12, and so that the first mattress core material 48 can be warmed by the heat of the hot water 20. For example, in order to support the hose 14, the first mattress core material may include a lower core material and an upper core material which will be the lower part (the part on the bottom fabric 44 side) and upper part of the first mattress core material 48. A groove (or recess) for arranging the hose 14 is formed in the lower core material, and the hose 14 is placed in the groove. Then, the upper core material is placed on the lower core material in which the hose 14 is arranged. This gives the first mattress core material 48 through which the hose 14 is passed. For example, the hose 14 may be housed in a groove (or recess) formed on the surface of the first mattress core material 48 (the side opposite to the bottom fabric 44). The grooves and other parts where the hose 14 is placed should extend according to the arrangement of the hose 14 (for example, a meandering arrangement).

[0041] The first mattress core material 48 is heated by the hot water 20 flowing through the hose 14. Therefore, the first mattress core material 48 has thermal conductivity that allows it to transfer heat from the hot water 20. The thermal conductivity of the first mattress core material 48 is, for example, 0.01 W / mK to 0.5 W / mK, preferably 0.04 W / mK to 0.1 W / mK. The first mattress core material 48 may also have elasticity. This elasticity is such that the mattress body 12 can be used as a mattress, and also such that the shape of the hose 14 can be maintained so that the flow of hot water 20 in the hose 14 is not obstructed when the user uses the mattress body 12. The thickness of the first mattress core material 48 is greater than the diameter of the hose 14. The thickness of the first mattress core material 48 is, for example, 5 mm to 15 mm. In one embodiment, the thickness of the first mattress core material 48 is 10 mm. The first mattress core material 48 is formed from, for example, a nonwoven fabric. Examples of nonwoven fabric materials used for the first mattress core material include polyester, polypropylene, and the like.

[0042] The second mattress core material 50 is placed on the first mattress core material 48. The second mattress core material 50 has a plurality of tiles 502. The second mattress core material 50 may have a support sheet 501 that supports the plurality of tiles 502. Unless otherwise specified, the description will focus on the second mattress core material 50 having the support sheet 501.

[0043] The support sheet 501 is placed on the first mattress core material 48. The support sheet 501 supports a plurality of tiles 502. The thickness of the support sheet 501 is, for example, 1 mm to 15 mm. The support sheet 501 has thermal conductivity. The thermal conductivity of the support sheet 501 is, for example, the same as that of the first mattress core material 48. The support sheet 501 may be flexible. The support sheet 501 can be formed from, for example, a nonwoven fabric, urethane, etc. Examples of nonwoven fabric materials used for the support sheet 501 are polypropylene and polyester. The support sheet 501 is preferably formed from, for example, a conductive nonwoven fabric. A conductive nonwoven fabric is, for example, a nonwoven fabric containing carbon fiber.

[0044] Tile 502 is a far-infrared radiator that emits far-infrared rays when heated. The material of Tile 502 is, for example, sericite It is terahertz ore and silicon. From the standpoint of the efficiency of far-infrared radiation, the material of tile 502 is sericite This is preferable. In this case, tile 502 is sericite It is a tile. The plan view shape of tile 502 is, for example, a quadrilateral (square, rectangle, etc.). If the plan view shape of tile 502 is a square, an example of the length of one side of tile 502 is 10 mm to 50 mm. In one embodiment, the length of one side of a square tile 502 is 38 mm. If tile 502 is a shape other than a square, tile 502 may be of a size that has a similar area to, for example, tile 502 if it is a square. The thickness of tile 502 is, for example, 1 mm to 5 mm. In one embodiment, the thickness of tile 502 is 4 mm. Tile 502 can be fixed to support sheet 501 by, for example, adhesive.

[0045] Multiple tiles 502 are arranged two-dimensionally in a predetermined area A (see Figure 1), for example. The number of tiles 502 can be determined, for example, depending on the size of the tiles 502 and the size of the predetermined area A. The number of tiles 502 is, for example, 80 to 1000. Multiple tiles 502 may be arranged evenly and discretely. Multiple tiles 502 may be divided into multiple groups, and the multiple tiles 502 within each group may be arranged evenly and discretely. The number of multiple tiles 502 included in each group may differ from group to group. Figure 3 shows an example in which 120 tiles 502 are divided into three groups, and the multiple tiles 502 included in each group are arranged two-dimensionally.

[0046] The cushion member 52 is placed on the second mattress core material 50. The cushion member 52 is a three-dimensional structure with resilience. The cushion member 52 has the function of mitigating the unevenness caused by the arrangement of multiple tiles 502 on the support sheet 501. The cushion member 52 may be made of, for example, polyester, polyethylene, etc. The cushion member 52 may also be made of urethane, nonwoven fabric, etc. Examples of nonwoven fabrics used for the cushion member 52 include V-Lap® nonwoven fabric and urethane nonwoven fabric. The cushion member 52 is preferably made of V-Lap® nonwoven fabric or a similar highly breathable cushioning material because it has high resilience. The thickness of the cushion member 52 is, for example, 5 mm to 15 mm. In one embodiment, the thickness of the cushion member 52 is 5 mm.

[0047] The heat-conducting sheet 54 is a sheet for conducting heat from the hot water 20. The heat-conducting sheet 54 has higher thermal conductivity than the first mattress core material 48. Therefore, it is easy to transfer heat to the entire mattress body 12. The heat-conducting sheet 54 may also have the function of emitting far-infrared rays when heated by the heat of the hot water 20 or the like. The heat-conducting sheet 54 can be formed from, for example, fibers kneaded with powdered charcoal (e.g., wood charcoal), carbon fiber, etc. In this way, when the heat-conducting sheet 54 contains charcoal (carbon), it has high thermal conductivity and can emit far-infrared rays. Furthermore, when the heat-conducting sheet 54 contains charcoal (carbon), it also has a deodorizing effect. The heat-conducting sheet 54 only needs to have a configuration that has higher thermal conductivity than the first mattress core material, and may have far-infrared radiating material (e.g., terahertz mineral) printed on it. An example of the thickness of the heat-conducting sheet 54 is 0.3 mm to 1 mm. In one embodiment, the thickness of the heat-conducting sheet 54 is 0.3 mm.

[0048] The outer fabric 56 is placed on the heat conductive sheet 54. As described above, the outer fabric 56 may be sized to cover the laminate formed by the heat insulating sheet 46, the first mattress core material 48, the second mattress core material 50, the cushioning member 52, and the heat conductive sheet 54, which are placed on the bottom fabric 44, and to be joined to the bottom fabric 44. The outer fabric 56 is formed, for example, by jacquard weaving.

[0049] The outer fabric 56 may contain terahertz wave emitters. An example of a terahertz wave emitter is terahertz ore, which is an artificial mineral. For example, fibers that have terahertz wave emitters kneaded into the fibers that make up the outer fabric 56 may be used, or a print containing terahertz wave emitters may be applied to the outer fabric 56. For example, a print may be applied to the fabric using a print material that contains powder of terahertz ore (terahertz wave emitter). For example, the above print containing powder of terahertz ore may be applied to, for example, 40% or more of the surface area in order to more effectively obtain the far-infrared radiation effect.

[0050] As shown in Figure 4, the far-infrared hot water mattress device 10 may also include covers 58 and 60.

[0051] The cover 58 is a mattress cover that accommodates the mattress body 12. The cover 58 is constructed in a bag-like or box-like shape so as to accommodate the mattress body 12. The cover 58 may be configured so that, for example, the front can be closed with a zipper or the like after the mattress body 12 has been placed inside. The cover 58 may be configured so that the outer hose portion 24 of the hose 14 can be positioned outside the cover 58. An example of the fabric for the cover 58 is a padded quilted fabric. The cover 58 is, sericite It may also contain far-infrared radiators such as the following. For example, cover 58 is sericite It may be formed by fibers into which such far-infrared radiating materials are kneaded, or, sericite The cover 58 may be printed with a print material containing far-infrared radiators (for example, powdered far-infrared radiators). sericiteThe material may be formed from fibers that have far-infrared radiators kneaded into them, or the cover may be printed with a print material that also contains far-infrared radiators.

[0052] Cover 60 is a cylindrical hose cover that covers the outer hose portion 24 of the hose 14. Cover 60 may be the same as cover 58 except for its shape.

[0053] In the far-infrared hot water mattress device 10 described above, hot water 20 flows through the hose 14 when the hot water supply unit 16 is driven. The inner hose portion 22 of the hose 14 is located on the first mattress core material 48. Therefore, the first mattress core material 48 is heated as the hot water 20 flows through the hose 14. As a result, other components (for example, the second mattress core material 50) provided on the first mattress core material 48 are heated, and the user of the mattress body 12 is also heated.

[0054] A second mattress core material 50, having multiple tiles 502, is provided on the first mattress core material 48. Each tile 502 is a far-infrared radiator. Therefore, as the temperature of the first mattress core material 48 rises and each tile 502 is heated, far-infrared rays are emitted from the tiles 502. As a result, the user of the mattress body 12 can obtain a warming effect from far-infrared rays in addition to the warming effect from the hot water 20. Therefore, by using the far-infrared hot water mattress device 10, the user's blood circulation is easily promoted, and as a result, the user's health can be improved. Metabolism is also easily promoted by the warming effects of the hot water 20 and far-infrared rays. In addition, since the human body is warmed with hot water 20, the user can be warmed gently or comfortably. Furthermore, the far-infrared effect warms the body from the inside. Therefore, the user can easily relax.

[0055] The far-infrared hot water mattress device 10 warms the user using hot water 20 and far-infrared rays, rather than electrically heating the mattress. Therefore, the user is less susceptible to the effects of radio waves. Thus, for example, users of implanted medical devices such as pacemakers can use the far-infrared hot water mattress device 10 with peace of mind.

[0056] The material for tile 502 is sericite In this case, tile 502 can emit more far-infrared rays. Therefore, it is possible to warm the user more effectively based on far-infrared radiation. sericite The far-infrared radiation tends to increase at approximately 38°C, which is slightly higher than human body temperature. When the user uses the mattress body 12, the tiles 502 are also warmed by the user's body temperature, and further, as described above, the tiles 502 are also warmed by the hot water 20. Therefore, the material of the tiles 502 sericite If that is the case, sericite The temperature tends to reach around 38°C. As a result, far-infrared rays are more easily emitted from tile 502. sericite Since it is also known to emit negative ions, it may also produce a relaxing effect based on negative ions.

[0057] In a configuration where the mattress body 12 further includes a heat-conducting sheet 54, the heat from the hot water 20 is easily transferred to the entire heat-conducting sheet 54 due to the high thermal conductivity of the heat-conducting sheet 54. As a result, the entire mattress body 12 is easily warmed in a plan view. If the heat-conducting sheet 54 contains, for example, charcoal or far-infrared radiating material, far-infrared rays can also be emitted from the heat-conducting sheet 54. Therefore, in a configuration where the mattress body 12 further includes a heat-conducting sheet 54, it is possible to warm the user even more. In a configuration where the heat-conducting sheet 54 contains charcoal, a deodorizing effect can also be obtained.

[0058] When the outer fabric 56 contains terahertz wave emitters (including cases where a print containing terahertz wave emitters is applied), terahertz waves are emitted from the outer fabric 56. This amplifies the thermal energy of the human body, making it possible to warm the user even more.

[0059] The far-infrared hot water mattress device 10 emits far-infrared radiation (for example, sericite In a configuration having a cover 58 including (including cases where a print containing terahertz wave radiators is applied), far-infrared radiation can be emitted from the far-infrared radiators, as in the case of the tile 502. As a result, the user is warmed more efficiently.

[0060] Various embodiments of the present invention have been described above. However, the present invention is not limited to the various embodiments described herein, and all modifications within the scope of the claims, the meaning and scope of equivalences to the claims, are intended to be included.

[0061] The flow path is not limited to a hose, but may be any pipe capable of carrying hot water, without departing from the spirit of the present invention.

[0062] The mattress itself may have, for example, a reflective sheet that reflects far-infrared rays instead of an insulating sheet. The reflective sheet is, for example, a sheet on which a reflective material such as aluminum foil is provided on the surface of a urethane sheet. [Explanation of Symbols]
