This application is based on Japanese Patent Application No. 2020-188753 filed on November 12, 2020 and claims the benefit of its priority, and all the contents of the patent application are Incorporated herein by reference.

This disclosure relates to a human body heating device that heats the human body.

A bathing method called "rock bath" is known, in which the human body is heated by using far infrared rays emitted from the bedrock. Equipment to enable such bedrock bathing has already been installed in some bathing facilities, etc., but it is expected that it will continue to be widely used in the future due to the growing health consciousness in recent years.

The present inventors have been enthusiastically engaged in research and development of a human body heating device in order to enable human body heating similar to that of a bedrock bath in many facilities including general residential houses. Examples of such a human body heating device include the mineral steam generating device described in Patent Document 1 below.

A mineral layer, a water supply pipe, a heater, etc. are provided on the lower side of the weight plate. In this device, water leaked from a hole in a water supply pipe is heated by a heater to generate steam. The generated water vapor heats the weight plate on the upper side and is supplied to the surroundings of the human body through the pores formed in the weight plate. Far-infrared rays and water vapor emitted from the weight plate raise the temperature inside the user's body. As a result, various effects such as recovery from fatigue, improvement of metabolism, and improvement of liver function can be obtained.

However, in the device described in Patent Document 1, it is necessary to install a water supply pipe, a heater, etc. on the lower side of the weight plate, and further, it is necessary to make adjustments for evenly generating water vapor in each part. There is. For this reason, special techniques and know-how are required for construction on buildings, and only a limited number of workers can perform construction work.

Hereinafter, this embodiment will be described with reference to the attached drawings. In order to facilitate the understanding of the description, the same components are designated by the same reference numerals as much as possible in each drawing, and duplicate description is omitted.

The first embodiment will be described. The human body heating device 10 according to the present embodiment is installed in, for example, a general residential house, and enables heating of the human body by a bedrock bath in a bathroom or the like of the residential house. FIG. 1 shows a configuration example of a room SR in which the human body heating device 10 is installed. In this example, the room SR is a space surrounded by a wall 13, and is provided as a dedicated room for installing the human body heating device 10. Reference numeral 11 in FIG. 1 is a door provided as an entrance to the room SR. In the following, the door will also be referred to as "door 11".

The room SR is provided with a pedestal surface 14 as a horizontal plane one step higher than the floor 12 in the vicinity of the door 11. A rectangular opening is formed on the pedestal surface 14 when viewed from above, and a plurality of floor members 20 which are a part of the human body heating device 10 are arranged so as to close the opening. Each floor member 20 is made by processing a rock having breathability such as a lava plate. The upper surface of the plurality of floor members 20 arranged side by side is a portion on which the user lies, that is, a portion on which the human body to be heated is placed. Each floor member 20 is identical to each other in its outer shape.

In the human body heating device 10, the floor member 20 is heated by a mechanism described later. At this time, the deep body temperature of the human body placed on the floor member 20 rises due to the far infrared rays and water vapor emitted from the floor member 20. As a result, various effects such as recovery from fatigue, improvement of metabolism, and improvement of liver function can be obtained.

An operation unit 30, which is a part of the human body heating device 10, is attached to the wall 13 of the room SR. The operation unit 30 is a remote controller operated by the user for the purpose of changing the temperature of the floor member 20, for example. The items set by the operation unit 30 will be described later.

FIG. 2 is a view of the human body heating device 10 installed in the room SR as viewed from above. The figure also shows a plurality of plate materials 60 arranged around the human body heating device 10. The upper surface of each plate 60 is the base surface 14 described above. Of the plurality of plate materials 60, the plate material 60 arranged at a position adjacent to the floor member 20 in the vicinity of the door 11 is particularly referred to as “plate material 61” below. The plate material 61 is formed with two inspection holes 62, which will be described later, so as to penetrate the plate material 61 in the vertical direction. In a normal state, the inspection hole 62 is closed by a lid (not shown).

As described above, a plurality of floor members 20 are arranged in the rectangular openings formed inside the plurality of plate materials 60. In FIG. 3, one floor member 20 is shown as a perspective view. The floor member 20 is a plate-shaped member formed so as to be square when viewed from above. In the present embodiment, as shown in FIG. 2, 10 floor members 20 are arranged so as to be arranged in 2 rows × 5 columns. The number and arrangement of the floor members 20 may be appropriately changed according to the shape and size of the room SR.

In this embodiment, two types of floor members 20 made of different materials are used. In FIGS. 1 and 2, the floor member 20 to which the reference numeral 21 is attached is formed by using a bedrock having a low rock density and a high porosity. The floor member 20 to which the reference numeral 21 is attached is also referred to as “floor member 21” below.

In FIG. 1 and the like, the floor member 20 to which the reference numeral 22 is attached is formed by using a bedrock having a high rock density and a low porosity as compared with the material of the floor member 21 described above. The floor member 20 to which the reference numeral 22 is attached is also referred to as “floor member 22” below.

The floor member 21 and the floor member 22 are arranged so as to be alternately arranged in the human body heating device 10. The reason why two types of members having relatively different rock densities and porosities are used as the floor member 20 will be described later.

FIG. 4 schematically shows the IV-IV cross section of FIG. As shown in the figure, the human body heating device 10 includes a hot water storage container 100, a stone receiving frame 200, and a gantry 300 in addition to the floor member 20.

The hot water storage container 100 is a stainless steel container whose upper side is open, and is for storing hot water on the lower side of the floor member 20. As shown in FIG. 4, the hot water storage container 100 is covered from above by a plurality of floor members 20 and plate members 61. Further, the side surface and the bottom surface of the hot water storage container 100 are covered from the outside by the heat insulating material 120.

In FIG. 5, the hot water storage container 100 is drawn in a top view. As shown in the figure, the outer shape of the portion of the hot water storage container 100 in which hot water is stored is substantially the same as the outer shape of all the floor members 20 and the plate 61 arranged as shown in FIG.

As shown in FIGS. 4 and 5, a support portion 110 is fixed to the inner surface of the hot water storage container 100 so as to extend over the entire circumference. The support portion 110 is a stainless steel plate-shaped member having an L-shaped cross section, and a part of the support portion 110 is welded to the inner surface of the hot water storage container 100. The remaining portion of the support portion 110 extends inward along the horizontal plane from the upper end of the portion welded to the inner surface of the hot water storage container 100 as described above. This portion is a portion that supports the stone receiving frame 200 described below from below at a predetermined height position.

The stone receiving frame 200 is placed on the support portion 110, and is a member for supporting a plurality of floor members 20 from below. In FIG. 6, the stone receiving frame 200 is drawn in a top view. As shown in the figure, the outer shape of the stone receiving frame 200 in the top view is substantially the same as the outer shape of all the floor members 20 and the plate members 61 arranged as shown in FIG.

The stone receiving frame 200 is formed by combining a plurality of stainless steel square pipes 210 and stainless steel support columns 211. As shown in FIG. 4, the support pillar 211 is a plate-shaped member having an L-shaped or T-shaped cross section.

The square pipe 210 is arranged so as to substantially follow the outer shapes of all the floor members 20 and the plate members 61 arranged as shown in FIG. The support pillars 211 are arranged inside the square pipe 210 along the boundary between the floor members 20 adjacent to each other and the boundary between the floor member and the plate member 61.

When the stone receiving frame 200 is viewed from above as shown in FIG. 6, a plurality of

openings

201 and 202 are formed in the stone receiving frame 200. The opening 201 is a rectangular opening formed at a position corresponding to each floor member 20. The opening 202 is a rectangular opening formed at a position corresponding to the plate member 61.

Each floor member 20 is provided so as to close the opening 201 from the upper side while its four sides are supported from below by the square pipe 210 and the support pillar 211. Therefore, each floor member 20 is in a state of directly touching the hot water stored in the hot water storage container 100 through the opening 201.

As shown in FIG. 4, the plate member 61 is supported from the lower side via the support member 220. The support member 220 is a member having a rectangular shape when viewed from above, which is formed by bending stainless steel. The support member 220 is provided so as to close the opening 202 of the stone receiving frame 200 from the upper side in a state where its four sides are supported from below by the square pipe 210 and the support pillar 211.

The plate member 61 is provided so as to further cover the support member 220 from above. The thickness of the support member 220 is substantially equal to the thickness of the floor member 20. Therefore, the height of the lower end surface of the plate member 61 arranged as described above is substantially equal to the height of the upper surface of the floor member 20. Among the support members 220, through holes 221 penetrating in the vertical direction are formed at each of the positions directly below the inspection holes 62 formed in the plate member 61.

The gantry 300 is for supporting the hot water storage container 100 from below on the floor 12 of the room SR. As shown in FIG. 4, a collar portion 103 is formed on the outer peripheral side of the hot water storage container 100, and the collar portion 103 is supported from the lower side by the gantry 300.

The gantry 300 is provided with a plurality of legs 310 so as to project downward, and the lower ends of the legs 310 are in contact with the floor 12. The length of each leg 310 can be adjusted by a screw (not shown). This makes it possible to make the upper end surface of the hot water storage container 100 along the horizontal plane.

Other configurations included in the human body heating device 10 will be described. As shown in FIG. 5, the human body heating device 10 further includes a water heater 40, a lead-in pipe 410, and a supply pipe 420.

The water heater 40 is a device for keeping the temperature of the hot water stored in the hot water storage container 100 at a predetermined temperature by drawing hot water from the hot water storage container 100, heating the water, and supplying the hot water to the hot water storage container 100. As the water heater 40, for example, a general gas water heater or the like can be used. The water heater 40 may be provided as a dedicated hot water supply device for the human body heating device 10, but may be provided as a hot water supply device that is also used as, for example, a kitchen or the like. In either case, the water heater 40 is installed outside the room SR. However, if an empty space can be secured in the space below the plate material 60, the water heater 40 may be installed in the space.

The lead-in pipe 410 is a pipe provided for drawing hot water from the hot water storage container 100 to the water heater 40. One end side of the lead-in pipe 410 is connected to the water heater 40. The other end side of the lead-in pipe 410 is connected to the bottom surface of the hot water storage container 100 at a position near the end portion on one end side along the longitudinal direction.

The end of the lead-in pipe 410 that is connected to the hot water storage container 100 as described above is also referred to as "first end 411" below. The first end portion 411 projects from the bottom surface of the hot water storage container 100 toward the inside of the hot water storage container 100, and an opening 412 serving as an inlet for hot water drawn from the hot water storage container 100 is formed at the tip thereof. In this way, the first end portion 411 of the lead-in pipe 410 is arranged inside the hot water storage container 100.

Of the hot water storage container 100, the side wall surface on one side along the longitudinal direction thereof, specifically, the side wall surface on the short side side on which the first end portion 411 is arranged nearby is described below. Then, it is also referred to as "wall surface 101". In FIG. 5, the direction in which hot water is drawn into the opening 412 of the first end portion 411 is indicated by the arrow AR1. The direction is a direction inclined by 45 degrees in the top view with respect to the normal direction of the wall surface 101, and is a direction toward the long side of the side where the first end portion 411 is arranged closer.

The supply pipe 420 is a pipe provided for supplying hot water from the water heater 40 to the hot water storage container 100. One end side of the supply pipe 420 is connected to the water heater 40. The other end side of the supply pipe 420 is a position on the bottom surface of the hot water storage container 100 that is close to the end portion on the one end side along the longitudinal direction, specifically, the one on which the first end portion 411 is arranged. It is connected to a position near the opposite end.

The end of the supply pipe 420 that is connected to the hot water storage container 100 as described above is also referred to as "second end 421" below. The second end portion 421 protrudes from the bottom surface of the hot water storage container 100 toward the inside of the hot water storage container 100, and an opening 422 serving as an outlet for hot water supplied to the hot water storage container 100 is formed at the tip thereof. .. In this way, the second end portion 421 of the supply pipe 420 is arranged inside the hot water storage container 100.

Of the hot water storage container 100, the side wall surface on one side along the longitudinal direction thereof, specifically, the side wall surface on the short side side on which the second end portion 421 is arranged nearby is described below. Then, it is also referred to as "wall surface 102". In FIG. 5, the direction in which hot water is supplied from the opening 422 of the second end portion 421 is indicated by the arrow AR2. The direction is a direction inclined by 45 degrees in the top view with respect to the normal direction of the wall surface 102, and is a direction away from the long side of the side where the second end portion 421 is arranged closer.

The human body heating device 10 further includes a drainage pipe 510 and an overflow pipe 520.

The drainage pipe 510 is a pipe for discharging the hot water stored in the hot water storage container 100 to the outside. One end of the drainage pipe 510 is connected to the drainage hole 512 formed at the bottom of the hot water storage container 100 from the lower side. The other end of the drainage pipe 510 is connected to a drainage pipe (not shown) provided in the building. A solenoid valve 513 is provided in the middle of the drainage pipe 510. The solenoid valve 513 is a valve capable of switching its opening and closing according to a signal from the outside. The solenoid valve 513 is closed during normal times when the human body heating device 10 is used. The opening / closing operation of the solenoid valve 513 is controlled by the control device 50 described later.

The overflow pipe 520 is a pipe for discharging excess hot water to the outside so that the water level of the hot water stored in the hot water storage container 100 does not exceed the predetermined water level. As shown in FIG. 4, the overflow pipe 520 is arranged so as to extend upward from the bottom of the hot water storage container 100, and an opening 521 facing upward is formed at the upper end thereof. .. The height position where the opening 521 is arranged is higher than the lower end position of the floor member 20 and lower than the upper end position of the floor member 20. Two overflow pipes 520 are provided. The opening 521 of each overflow pipe 520 is arranged at a position directly below the inspection hole 62 formed in the plate material 61. In the portion below the hot water storage container 100, each overflow pipe 520 is connected to a portion of the drainage pipe 510 on the downstream side of the solenoid valve 513.

In FIG. 4, the code "WS" is attached to indicate the water surface of the hot water stored in the hot water storage container 100. When the water level of the hot water stored in the hot water storage container 100 (that is, the height of the water surface WS) exceeds the opening 521, a part of the hot water flows into the overflow pipe 520 from the opening 521. Therefore, the water level of the hot water is always maintained at the same water level as the height position of the opening 521. The pair of overflow pipes 520 and the drainage pipes 510 connected to them correspond to a "water level maintenance unit" for maintaining the water level of the hot water stored in the hot water storage container 100 at a predetermined water level. The overflow pipe 520 can be said to be a pipe having an opening 521 formed at the above-mentioned predetermined water level.

As shown in FIG. 5, the human body heating device 10 further includes a control device 50. The control device 50 is a computer system for controlling the overall operation of the human body heating device 10, and is arranged, for example, outside the room SR. The control device 50 controls the operation of the water heater 40, the solenoid valve 513, and the like based on the user's operation performed on the operation unit 30.

The operation of the human body heating device 10 will be described. When the user performs an operation for starting the operation of the human body heating device 10 on the operation unit 30, the control device 50 operates the water heater 40 to fill the hot water storage container 100 with hot water. The water heater 40 supplies hot water from the supply pipe 420 to the hot water storage container 100 based on the signal from the control device 50.

At this time, the temperature of the hot water supplied from the water heater 40 is set to the target hot water temperature transmitted from the control device 50 to the water heater 40. The target hot water temperature is a desired temperature set by the user by operating the operation unit 30 in advance. The target hot water temperature is preferably set so that the temperature of the floor member 20 is in the range of, for example, 43 to 45 ° C.

After the hot water filling of the hot water storage container 100 is completed and the hot water storage container 100 reaches the above-mentioned predetermined water level (height of the opening 521), the human body heating device 10 can be used. The user can take a bedrock bath by lying on the upper surface of the floor member 20.

As described above, in the present embodiment, the water level (predetermined water level) of the hot water in the hot water storage container 100 is higher than the lower end position of the floor member 20 and lower than the upper end position of the floor member 20. In addition, the position of the opening 521 of the overflow pipe 520 is adjusted. Since the lower portion of each floor member 20 is immersed in hot water, the floor member 20 is directly heated by the hot water to raise the temperature. The human body placed on the floor member 20 is heated not only by heat conduction from the floor member 20, but also by far infrared rays emitted from the floor member 20. As a result, the core body temperature of the human body rises efficiently.

As described above, the human body heating device 10 is configured so that the floor member 20 is heated by the heat of the hot water stored in the hot water storage container 100. In such a human body heating device 10, the human body placed on the floor member 20 is heated by far infrared rays or the like to recover from fatigue, etc., while having a simple configuration in which the upper side of the hot water storage container 100 is covered with the floor member 20. Various effects can be obtained. Further, when constructing the human body heating device 10 having such a configuration in a building, the same know-how and technique as when constructing a general bathtub can be used as it is. That is, since no special know-how or technique is required to construct the human body heating device 10 according to the present embodiment, it can be easily constructed by, for example, a worker of a waterworks shop.

Each floor member 20 is formed of breathable lava. Therefore, water vapor is released upward through the innumerable pores formed in each floor member 20. The human body is also heated by this water vapor. In addition, since the temperature and humidity of the room SR rise, the effect of relaxing the user can also be obtained.

As described above, in the present embodiment, two types of members having relatively different rock densities and porosities are used as the floor member 20. In the portion of the floor member 21 where the rock density is low and the porosity is high, more water vapor is released upward. On the other hand, in the portion of the floor member 22 having a high rock density and a low porosity, the amount of water vapor released is suppressed, but the temperature of the floor member 22 tends to rise by that amount. As described above, in the human body heating device 10 according to the present embodiment, the floor member 21 in which the amount of water vapor released is large and the floor member 22 in which the temperature is likely to rise are alternately arranged to form the human body. The balance between the amount of heating and the amount of steam is adjusted.

After the completion of filling the hot water storage container 100 with hot water, hot water is continuously supplied from the supply pipe 420 and hot water is started to be drawn from the lead-in pipe 410. Such switching of operations is performed based on a control signal transmitted from the control device 50 to the water heater 40. The water heater 40 heats the hot water drawn from the hot water storage container 100 through the lead-in pipe 410 to the above target hot water temperature, and then supplies the hot water from the hot water storage pipe 420 to the hot water storage container 100.

That is, the control device 50 adjusts the temperature of the hot water stored in the hot water storage container 100 and keeps it at the target hot water temperature while circulating hot water between the hot water storage container 100 and the water heater 40. The water heater 40 and the control device 50 correspond to a "hot water temperature adjusting unit" for adjusting the temperature of the hot water stored in the hot water storage container 100. Since the temperature of the hot water is maintained at the target hot water temperature, the temperature of the floor member 20 does not decrease with time, and the user can enjoy the bedrock bath for a long time. In this embodiment, the pipe for supplying hot water at the time of filling with hot water and the pipe for supplying hot water after filling with hot water are used in one supply pipe 420. Instead of such an embodiment, a dedicated pipe for supplying hot water at the time of filling with hot water may be provided separately from the supply pipe 420.

As described above, the control device 50 and the water heater 40 included in the hot water temperature adjusting unit adjust the temperature of the hot water stored in the hot water storage container 100 so as to be a predetermined target hot water temperature. This target hot water temperature is set by the control device 50 based on the user's operation performed on the operation unit 30. The operation unit 30 and the control device 50 correspond to the "hot water temperature setting unit" in the present embodiment. The user can change the temperature of the hot water by changing the target hot water temperature according to his / her taste, and as a result, change the temperature of the floor member 20.

In order to enable the temperature of hot water to be adjusted by the water heater 40, for example, a temperature sensor for measuring the temperature of hot water may be provided in the middle of the lead-in pipe 410 or inside the water heater 40. In this case, the water heater 40 adjusts the heating amount for the hot water so that the temperature of the hot water flowing through the lead-in pipe 410 matches the target hot water temperature.

In the present embodiment, the first end portion 411 of the lead-in pipe 410 is arranged at a position near the wall surface 101 on one side along the longitudinal direction of the hot water storage container 100. Further, the second end portion 421 of the supply pipe 420 is arranged at a position near the wall surface 102 on the other side along the longitudinal direction of the hot water storage container 100.

Further, in the present embodiment, the direction in which the hot water is drawn into the first end portion 411 is a direction inclined with respect to the wall surface 101 as shown by the arrow AR1 in FIG. Further, the direction in which hot water is supplied from the second end portion 421 is a direction inclined with respect to the wall surface 102 as shown by the arrow AR2 in FIG.

In such a configuration, the hot water supplied to the hot water storage container 100 from the opening 422 of the second end 421 flows through substantially the entire hot water storage container 100 while swirling clockwise in a top view, and then first. It will be discharged from the opening 412 of the end 411. As a result, it is possible to prevent temperature unevenness from occurring in the hot water stored in the hot water storage container 100, so that the entire plurality of floor members 20 can be heated substantially uniformly.

When the bedrock bath is completed, the user stops the operation of the water heater 40 by operating the operation unit 30. The control device 50 opens the solenoid valve 513 and discharges hot water from the hot water storage container 100 based on a further investigation conducted on the operation unit 30.

As described above with reference to FIG. 4, the opening 521 of the overflow pipe 520 is arranged at a position directly below the inspection hole 62 formed in the plate material 61. The user can visually check the situation around the opening 521 by looking into the inspection hole 62 from above. As a result, the user can confirm whether or not hot water is present inside the hot water storage container 100, confirm whether or not the solenoid valve 513 is operating normally, and the like.

The second embodiment will be described. The present embodiment is different from the first embodiment in the configuration of some floor members 20 and the content of the processing performed by the control device 50. In the following, the points different from the first embodiment will be mainly described, and the points common to the first embodiment will be omitted as appropriate.

As shown in FIG. 7, in the present embodiment, the recess 23 is formed in one of the plurality of floor members 20, and the temperature sensor 24 is attached to the inside of the recess 23. The temperature sensor 24 is a sensor for measuring the temperature of the floor member 20, for example, a thermistor. A signal indicating the temperature measured by the temperature sensor 24 is input to the control device 50.

The recess 23 is formed at a position centered on the floor member 20 when viewed from above. Further, the depth of the recess 23 is ½ of the thickness of the floor member 20. Therefore, what is measured by the temperature sensor 24 is the temperature at the center of the floor member 20.

In the present embodiment, the user can set the target floor temperature, which is the target value for the temperature of the floor member 20, by operating the operation unit 30. The target floor temperature is preferably set in the range of, for example, 43 to 45 ° C. During the operation of the human body heating device 10, the control device 50 controls the operation of the water supply device 40 so that the temperature of the floor member 20 measured by the temperature sensor 24 becomes the target floor temperature, and is stored in the hot water storage container 100. Adjust the temperature of the hot water. For example, when the temperature of the floor member 20 measured by the temperature sensor 24 is lower than the target floor temperature, the temperature of the hot water supplied from the water heater 40 through the supply pipe 420 is made higher than before. On the contrary, when the temperature of the floor member 20 measured by the temperature sensor 24 is higher than the target floor temperature, the temperature of the hot water supplied from the water heater 40 through the supply pipe 420 is made lower than before. The supply of hot water from the water heater 40 may be temporarily stopped.

The target floor temperature is set by the control device 50 based on the user's operation performed on the operation unit 30. The operation unit 30 and the control device 50 correspond to the "floor temperature setting unit" in the present embodiment. Also in this embodiment, the user can change the temperature of the hot water by changing the target floor temperature according to his / her preference, and as a result, change the temperature of the floor member 20. In the present embodiment, since the user directly sets the target value for the temperature of the floor member 20, a more comfortable bedrock bath can be provided to the user.
