Summary of the Invention

Problems to be Solved by the Invention

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

[0005] One object of the present invention is to provide a far-infrared warm water mattress device capable of promoting the health of a 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 disposed outside the mattress body and supplying warm water to the flow path. The mattress body has a first mattress core material having thermal conductivity and a second mattress core material disposed on the first mattress core material and including 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, warm water flows through the flow path by the warm water supply unit. A part of the flow path is arranged in contact with a first mattress core material having thermal conductivity within the mattress body. In this configuration, since the first mattress core material is warmed by the warm water, the user using the mattress body is also warmed. A second mattress core material including a plurality of far-infrared radiators is arranged on the first mattress core material. Therefore, when the first mattress core material is warmed, far-infrared rays are radiated from the plurality of far-infrared radiators included in the second mattress core material. The user is also warmed by this far-infrared ray. Thus, in the far-infrared warm water mattress device, since the user is warmed by warm water and far-infrared rays, for example, the blood circulation of the user is improved and the health of the user can be enhanced.

[0008] A part of the above flow path may meander when the above mattress body is viewed from the thickness direction. Thereby, it is possible to warm a wider area of the user's body.

[0009] The above far-infrared radiator may be a tile formed of tourmaline. Tourmaline is known to have a high far-infrared radiation ability. Therefore, it is possible to warm the user more.

[0010] The above configuration further includes a cushion member arranged on the second mattress core material. The second mattress core material is provided on the first mattress core material and has a support sheet that supports the plurality of far-infrared radiators. The plurality of far-infrared radiators may be provided on the support sheet on the cushion member side.

[0011] In the above configuration, a plurality of far-infrared radiators are arranged on the support sheet. In this case, the second mattress core material has, for example, unevenness on the side opposite to the first mattress core material. Thus, even if the second mattress core material has unevenness, since the mattress body has the cushion member, the influence of the unevenness can be mitigated by the cushion member.

[0012] The above mattress body 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 is warmed more.

[0013] The above mattress body may further have a heat conduction 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, when viewed from the thickness direction of the mattress body, heat is easily transmitted throughout the mattress body.

[0014] The above mattress body may have at least one of heat insulation and far-infrared ray reflectivity on the side opposite to the second mattress core material when viewed from the first mattress core material. Thereby, for example, it is easier to warm the user.

[0015] It further has a mattress cover for accommodating the above mattress body, and the above mattress cover may contain far-infrared ray emitters. Since far-infrared rays can also be emitted from the mattress cover, the warming effect by far-infrared rays can be enhanced.

Advantages of the Invention

[0016] According to one aspect of the present invention, it is possible to provide a far-infrared warm water mattress device capable of promoting the health of the user.

Best Mode for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and redundant explanations 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 warm water mattress device 10 according to an embodiment. As shown in FIG. 1, the far-infrared warm water mattress device 10 includes a mattress body 12, a hose 14 (flow path), and a warm water supply unit 16. In the far-infrared warm water mattress device 10, warm water 20 (see FIG. 2) is passed through the hose 14 to warm the mattress body 12. Thereby, the user of the mattress body 12 is warmed.

[0020] The mattress body 12 in the present embodiment is a mattress that the 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 for passing warm water 20. The temperature of the warm water 20 is, for example, 30°C to 70°C. The hose 14 has heat resistance to allow warm 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 portion 22 is arranged to warm the entire predetermined region A (the region indicated by the dashed-dotted line) when the mattress body 12 is viewed in plan (when viewed from the thickness direction). For example, the inner hose portion 22 meanders (or bends multiple times) within the predetermined region A. For example, the inner hose portion 22 has a plurality of straight regions 22a and a plurality of U-shaped regions 22b. The plurality of 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 portion 22 may be arranged in a bellows shape within the above-described predetermined region A. The predetermined region A is, for example, a region where it can be assumed that the user's torso and legs are located when the user lies on the mattress body 12. The predetermined region A can be, for example, a region of 20% or more of the area of the mattress body 12 when the mattress body 12 is viewed in plan. The predetermined region A may be, for example, 50% or 60% or more of the area of the mattress body 12 when the mattress body 12 is viewed in plan. The predetermined region A may be 100% or less, but may also be 90% or less, or 80% or less. When the mattress body 12 has a size of 100 cm × 200 cm, the predetermined region A is, for example, 80 cm × 150 cm in size. The outer hose portion 24 is connected to the hot water supply portion 16.

[0023] The hot water supply portion 16 flows hot water 20 at a constant temperature into the hose 14. The hot water supply portion 16 can be a device for operating the far-infrared hot water mattress device 10. In the present embodiment, the hot water supply portion 16 is a small boiler unit (or a water heater). That is, the water supplied to the hot water supply portion 16 is boiled to generate the hot water 20. The hot water supply portion 16 flows the generated hot water 20 into the hose 14. The hot water supply portion 16 only needs to be configured to be able to flow the hot water 20 at a constant temperature into the hose 14.

[0024] An example of the hot water supply portion 16 will be described with reference to FIGS. 1 and 2. FIG. 2 is a schematic diagram for explaining the configuration of an example of the hot water supply portion 16. In FIG. 2, the illustration of the housing of the hot water supply portion 16 is omitted.

[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 adjustment unit) 36, an operation unit 38, and a control unit 40.

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

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

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

[0029] The pump 32 is attached to the pipe 30a. The pump 32 is a machine for flowing the hot water 20 into the hose 14. The pump 32 can be driven electrically. The pump 32 may be attached to the pipe 30b.

[0030] The heater 36 heats the water supplied into the storage unit 28 to generate the hot water 20. The heater 36 also has a 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 warm water 20. As long as it can measure the temperature of the warm water 20, the installation position of the temperature sensor 34 is not limited. As the temperature sensor 34, for example, a sensor used in a household water heater or a boiler device may be used.

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

[0033] The display unit 38b is a part that displays the operation state of the far-infrared warm water mattress device 10. The display unit 38b displays, for example, whether the far-infrared warm water mattress device 10 is in the ON state or the OFF state. When the reservation time (operation start time), usage time, etc. of the far-infrared warm water mattress device 10 are set by the timer, the display unit 38b may display the operation start time, remaining usage time, etc. of the far-infrared warm water mattress device 10. When the user specifies the temperature of the warm water 20, the display unit 38b may display the temperature input by the user, the actual temperature of the warm water 20, etc.

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

[0035] The control unit 40 controls the hot water supply unit 16. For example, the control unit 40 controls the heater 36 so that the temperature of the hot water 20 becomes a preset temperature or the temperature received by the input unit 38a, and adjusts the temperature of the hot water 20. At this time, the control unit 40 performs feedback control on the heater 36 based on, for example, the measurement result of the temperature sensor 34. The control unit 40 may cause the display unit 38b to display the measurement result of the temperature sensor 34. 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] FIG. 3 is an exploded view showing an example of the 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 include at least one of a bottom fabric 44, a heat insulating sheet 46, a cushion member 52, a heat conductive sheet 54, and a top fabric 56. Hereinafter, unless otherwise specified, the mattress body 12 having the bottom fabric 44, the heat insulating sheet 46, the cushion member 52, the heat conductive sheet 54, and the top fabric 56 will be described.

[0037] The heat insulating sheet 46, the first mattress core material 48, the second mattress core material 50, the cushion member 52, the heat conductive sheet 54, and the top fabric 56 are laminated on the bottom fabric 44 in this order. The planar shapes of the bottom fabric 44, the heat insulating sheet 46, the first mattress core material 48, the second mattress core material 50, the cushion member 52, and the heat conductive sheet 54 are the same as the planar shape of the mattress body 12, and are rectangular in the present embodiment. The top fabric 56 can be joined to the bottom fabric 44 in a state of covering the laminate formed by, for example, the heat insulating sheet 46, the first mattress core material 48, the second mattress core material 50, the cushion member 52, and the 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 peripheral portions 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. Also in this case, the peripheral fabric may be sewn to the bottom fabric 44 and the top fabric 56.

[0038] The bottom fabric 44 is disposed on the bottom side (e.g., the floor side) of the mattress body 12. The bottom fabric 44 may have an anti-slip function. Examples of the material of the bottom fabric 44 are polyvinyl chloride (PVC), polyester, nylon, etc. 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 heat insulation sheet 46 is disposed on the bottom fabric 44. The heat insulation sheet 46 is, for example, a sheet for preventing the temperature of the mattress body 12 from dropping due to, for example, the floor on which the mattress body 12 is disposed. The heat insulation sheet 46 may have flexibility. Examples of the material of the heat insulation sheet 46 include polyurethane, PVC, and aluminum foil. The thickness of the heat insulation sheet 46 is, for example, 0.5 mm to 2 mm. In one embodiment, the thickness of the heat insulation sheet 46 is 2 mm.

[0040] The first mattress core material 48 is disposed on the heat 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 such that warm water 20 can flow through the hose 14 even when the user uses the mattress body 12 and the first mattress core material 48 can be warmed by the heat of the warm 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 that are to be the lower part (the part on the bottom fabric 44 side) and the upper part of the first mattress core material 48. A groove (or recess) for disposing the hose 14 is formed in the lower core material, and the hose 14 is disposed in the groove. Then, the upper core material is disposed on the lower core material on which the hose 14 is disposed. Thereby, the first mattress core material 48 through which the hose 14 passes is obtained. For example, the hose 14 may be accommodated in a groove (or recess) formed on the surface (the surface opposite to the bottom fabric 44) of the first mattress core material 48. The portion where the hose 14 is disposed, such as the groove described above, may extend according to the disposition state (e.g., a meandering state) of the hose 14.

[0041] The first mattress core 48 is warmed by the warm water 20 flowing through the hose 14. Therefore, the first mattress core 48 has heat conductivity capable of transferring heat by the warm water 20. The heat conductivity of the first mattress core 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 48 may have elasticity to transfer the heat of the warm water 20. The elasticity is such that the mattress body 12 can be used as a mattress, and can maintain the shape of the hose 14 so that, for example, the flow of the warm water 20 in the hose 14 is not obstructed when a user uses the mattress body 12. The thickness of the first mattress core 48 is larger than the diameter of the hose 14. The thickness of the first mattress core 48 is, for example, 5 mm to 15 mm. In one embodiment, the thickness of the first mattress core 48 is 10 mm. The first mattress core 48 is formed of, for example, a non-woven fabric. Examples of the material of the non-woven fabric used for the first mattress core are polyester, polypropylene, etc.

[0042] The second mattress core 50 is disposed on the first mattress core 48. The second mattress core 50 has a plurality of tiles 502. The second mattress core 50 may have a support sheet 501 that supports the plurality of tiles 502. Unless otherwise noted, the second mattress core 50 having the support sheet 501 will be described.

[0043] The support sheet 501 is disposed on the first mattress core 48. The support sheet 501 supports the plurality of tiles 502. The thickness of the support sheet 501 is, for example, 1 mm to 15 mm. The support sheet 501 has heat conductivity. The heat conductivity of the support sheet 501 is, for example, the same as that of the first mattress core 48. The support sheet 501 may have flexibility. The support sheet 501 can be formed of, for example, a non-woven fabric, urethane, etc. Examples of the material of the non-woven fabric used for the support sheet 501 are polypropylene and polyester. The support sheet 501 is preferably formed of, for example, a conductive non-woven fabric. The conductive non-woven fabric is, for example, a non-woven fabric containing carbon fibers.

[0044] The tile 502 is a far-infrared radiator that emits far-infrared rays when heated. The material of the tile 502 is, for example, sericite (muscovite), terahertz ore, or silicon. From the perspective of the efficiency of far-infrared radiation, the sericite is preferred as the material of the tile 502. In this case, the tile 502 is a sericite tile. The planar shape of the tile 502 is, for example, a quadrilateral (such as a square or a rectangle). When the planar shape of the tile 502 is a square, an example of the length of one side of the tile 502 is 10 mm to 50 mm. In one embodiment, the length of one side of the square tile 502 is 38 mm. When the tile 502 has a shape other than a square, the tile 502 can be sized to have, for example, the same area as when the tile 502 is a square. The thickness of the tile 502 is, for example, 1 mm to 5 mm. In one embodiment, the thickness of the tile 502 is 4 mm. The tile 502 can be fixed to the support sheet 501 by, for example, an adhesive.

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

[0046] The cushion member 52 is disposed on the second mattress core material 50. The cushion member 52 is a three-dimensional structure having resilience. The cushion member 52 has a function of alleviating unevenness associated with a plurality of tiles 502 being disposed on the support sheet 501. The cushion member 52 can be formed of, for example, polyester, polyethylene, or the like. The cushion member 52 may be formed of urethane, non-woven fabric, or the like. Examples of the non-woven fabric used for the cushion member 52 include V-Lap (registered trademark) non-woven fabric, urethane non-woven fabric, and the like. The cushion member 52 is preferably formed of a V-Lap (registered trademark) non-woven fabric or a cushion material having good air permeability similar thereto because it has, for example, 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 conduction sheet 54 is a sheet for conducting the heat of the warm water 20. The heat conduction 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 conduction sheet 54 may have a function of emitting far-infrared rays when warmed by the heat of the warm water 20 or the like. The heat conduction sheet 54 can be formed of, for example, fibers kneaded with powdered charcoal (for example, charcoal), carbon fiber, or the like. Thus, when the heat conduction sheet 54 contains carbon, it has high thermal conductivity and can emit far-infrared rays. Further, when the heat conduction sheet 54 contains carbon, it also has a deodorizing effect. The heat conduction sheet 54 only needs to have a configuration having higher thermal conductivity than the first mattress core material, and far-infrared ray emitters (for example, terahertz ore) may be printed thereon. An example of the thickness of the heat conduction sheet 54 is 0.3 mm to 1 mm. In one embodiment, the thickness of the heat conduction sheet 54 is 0.3 mm.

[0048] The top fabric 56 is disposed on the heat conduction sheet 54. As described above, the top fabric 56 covers the laminate formed by the heat insulation sheet 46, the first mattress core material 48, the second mattress core material 50, the cushion member 52, and the heat conduction sheet 54 disposed on the bottom fabric 44, and may have a size that can be joined to the bottom fabric 44. The top fabric 56 is formed, for example, by jacquard weaving.

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

[0050] As shown in FIG. 4, the far-infrared warm water mattress device 10 may include a cover 58 and a cover 60.

[0051] Cover 58 is a mattress cover that houses the mattress body 12. The cover 58 is configured in a bag shape or a box shape so as to be able to house the mattress body 12. The cover 58 can be configured, for example, to have its surface closed with a fastener or the like after housing the mattress body 12. The cover 58 can be configured such that the outer hose portion 24 of the hose 14 can be disposed outside the cover 58. An example of the fabric of the cover 58 is a quilted fabric with batting. The cover 58 may contain a far-infrared radiation-emitting substance such as sericite. For example, the cover 58 may be formed of fibers in which a far-infrared radiation-emitting substance such as sericite is kneaded, or a print may be applied to the cover 58 with a printed material containing a far-infrared radiation-emitting substance (for example, a powdery far-infrared radiation-emitting substance). The cover 58 may be formed of fibers in which a far-infrared radiation-emitting substance such as sericite is kneaded and a print may be applied to the cover with a printed material containing a far-infrared radiation-emitting substance.

[0052] Cover 60 is a tubular hose cover that covers the outer hose portion 24 of the hose 14. The cover 60 can be the same as the cover 58 except for the different shape.

[0053] In the above-described far-infrared warm water mattress device 10, when the warm water supply unit 16 is driven, warm water 20 flows into the hose 14. The inner hose portion 22 of the hose 14 is disposed in the first mattress core material 48. Therefore, when warm water 20 flows through the hose 14, the first mattress core material 48 is warmed. As a result, other members (for example, the second mattress core material 50) provided on the first mattress core material 48 are warmed, so that the user of the mattress body 12 is also warmed.

[0054] On the first mattress core material 48, a second mattress core material 50 having a plurality of tiles 502 is provided. Each tile 502 is a far-infrared radiator. Therefore, when each tile 502 is warmed as the temperature of the first mattress core material 48 rises, far-infrared rays are radiated from the tile 502. Thereby, the user of the mattress body 12 can obtain a warming effect by far-infrared rays in addition to the warming effect by the warm water 20. Therefore, when the user uses the far-infrared warm water mattress device 10, the blood circulation of the user is likely to be promoted, and as a result, it is possible to improve the health of the user. The warming effect of the warm water 20 and far-infrared rays also easily promotes metabolism. In addition, since the human body is warmed by the warm water 20, it is possible to gently or slowly warm the user. Furthermore, due to the far-infrared ray effect, the human body is warmed from the inside. Therefore, the user is likely to relax.

[0055] In the far-infrared warm water mattress device 10, instead of electrically warming the mattress, the user is warmed using the warm water 20 and far-infrared rays. Therefore, the user is less likely to be affected by radio waves. Thus, for example, even a user of an implanted medical device such as a pacemaker can use the far-infrared warm water mattress device 10 with confidence.

[0056] When the material of the tile 502 is tourmaline, the tile 502 can emit more far-infrared rays. Therefore, based on the far-infrared rays, it is possible to warm the user more. Tourmaline has a tendency for the emission of far-infrared rays to increase at about 38°C, which is slightly higher than the human body temperature. When the user uses the mattress body 12, the tile 502 is also warmed by the body temperature of the user, and furthermore, as described above, the tile 502 is also warmed by the warm water 20. Therefore, when the material of the tile 502 is tourmaline, tourmaline is likely to reach about 38°C. As a result, far-infrared rays are more easily emitted from the tile 502. Tourmaline is also known to emit negative ions, so it can also exhibit a relaxation effect based on negative ions.

[0057] In a form where the mattress body 12 further has a heat conduction sheet 54, the heat of the warm water 20 is easily transmitted to the entire heat conduction sheet 54 by the heat conduction sheet 54 having high heat conductivity. As a result, the entire mattress body 12 is easily warmed in a plan view. When the heat conduction sheet 54 contains, for example, charcoal or a far-infrared radiation substance, far-infrared rays can also be radiated from the heat conduction sheet 54. Therefore, in a form where the mattress body 12 further has the heat conduction sheet 54, it is possible to warm the user further. In a form where the heat conduction sheet 54 contains charcoal, a deodorizing effect can also be obtained.

[0058] In a form where the surface fabric 56 contains a terahertz wave radiation substance (including the case where a print containing a terahertz wave radiation substance is applied), terahertz waves are radiated from the surface fabric 56. Thereby, the thermal energy of the human body is amplified, and it is possible to warm the user further.

[0059] In a form where the far-infrared warm water mattress device 10 has a cover 58 containing a far-infrared radiation substance (such as tourmaline) (including the case where a print containing a terahertz wave radiation substance is applied), similar to the case of the tile 502, far-infrared rays can be radiated from the above far-infrared radiation substance. As a result, the user is warmed more efficiently.

[0060] The various embodiments of the present invention have been described above. However, the present invention is not limited to the various illustrated embodiments, and it is intended that the scope indicated by the claims and all modifications within the meaning and scope equivalent to the claims be included.

[0061] The flow path is not limited to a hose, and any pipe that can flow warm water without departing from the gist of the present invention may be used.

[0062] Instead of the heat insulation sheet, the mattress body may have, for example, a reflection sheet that reflects far-infrared rays. The reflection sheet is, for example, a sheet in which a reflection member such as aluminum foil is provided on the surface of a urethane sheet.
