Description

TECHNICAL FIELD The present disclosure relates to a human body heating device that heats a human body.

2. Description of the Related Art A bathing method called “bedrock bath” is known, in which far infrared rays emitted from bedrock are used to heat the human body. Some bathing facilities have already installed facilities to enable such a bedrock bath, but it is believed that they will continue to spread widely in the future due to the recent rise in health consciousness.

The present inventors have devoted themselves to research and development of a human body heating apparatus in order to enable human body heating similar to bedrock bathing in many facilities including general residential houses. As such a human body heating device, for example, there is a mineral vapor 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 leaking from a hole in a water supply pipe is heated by a heater to generate steam. The generated steam heats the weight plate on the upper side and is supplied to the surroundings of the human body through pores formed in the weight plate. Far-infrared rays and water vapor emitted from the weight plate raise the user's internal temperature. 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 furthermore, it is necessary to make adjustments to generate steam evenly in each part. There is For this reason, special techniques and know-how were required for construction work on buildings, and only a limited number of workers could carry out construction work.

Hereinafter, this embodiment will be described with reference to the accompanying drawings. In order to facilitate understanding of the description, the same constituent elements in each drawing are denoted by the same reference numerals as much as possible, and overlapping descriptions are omitted.

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

The room SR is provided with a platform surface 14 as a horizontal surface that is one step higher than the floor 12 in the vicinity of the door 11 . A rectangular opening is formed in the base surface 14 when viewed from above, and a plurality of floor members 20, which are 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 permeable bedrock such as a lava plate. The upper surface of the floor members 20 arranged in a plurality is the part on which the user lies, that is, the part on which the human body to be heated is placed. Each floor member 20 is identical to each other in its external shape.

In the human body heating device 10, the floor member 20 is heated by a mechanism that will be described later. At this time, the deep body temperature of the human body placed on the floor member 20 rises due to 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 that is 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. Items set by the operation unit 30 will be described later.

FIG. 3 shows a single floor member 20 as a perspective view. The floor member 20 is a plate-like member formed to have a square shape when viewed from above. In this embodiment, as shown in FIG. 2, ten floor members 20 are arranged in two rows and five 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 denoted by reference numeral 21 is formed using a bedrock having a low rock density and a high porosity. The floor member 20 denoted by reference numeral 21 is hereinafter also referred to as "floor member 21".

In FIG. 1 and the like, the floor member 20 denoted by reference numeral 22 is formed using a bedrock having a higher rock density and a lower porosity than the material of the floor member 21 described above. The floor member 20 denoted by reference numeral 22 is hereinafter also referred to as "floor member 22".

The floor members 21 and the floor members 22 are arranged alternately 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 container 100, a stone receiving frame 200, and a pedestal 300 in addition to the floor member 20. As shown in FIG.

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 a stone support frame 200 described below from below at a predetermined height position.

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

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

The square pipes 210 are arranged so as to generally follow the contours of all the floor members 20 and plate members 61 arranged as shown in FIG. The support columns 211 are arranged inside the square pipes 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, the stone receiving frame 200 has a plurality of openings 201 and 202 formed therein. The openings 201 are rectangular openings formed at positions corresponding to the respective floor members 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 block the opening 201 from above while its four sides are supported from below by square pipes 210 and support columns 211 . Therefore, each floor member 20 is in direct contact with the hot water stored in the hot water container 100 through the opening 201 .

As shown in FIG. 4 , the plate member 61 is supported from below via a support member 220 . The support member 220 is a rectangular member formed by bending stainless steel. The support member 220 is provided so as to cover the opening 202 of the stone receiving frame 200 from above while its four sides are supported from below by the square pipe 210 and the support column 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 approximately 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 approximately equal to the height of the upper surface of the floor member 20 . Through-holes 221 are formed through the support member 220 in the vertical direction at respective positions directly below the inspection holes 62 formed in the plate member 61 .

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

The pedestal 300 is provided with a plurality of legs 310 projecting downward, and the lower end of each leg 310 is in contact with the floor 12 . The length of each leg 310 can be adjusted by screws (not shown). This allows the upper end surface of the hot water storage container 100 to be aligned with the horizontal plane.

Other configurations of 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 , lead-in piping 410 and supply piping 420 .

The water heater 40 draws in hot water from the hot water storage container 100, heats the hot water, and supplies the hot water to the hot water storage container 100 to keep the temperature of the hot water stored in the hot water storage container 100 at a predetermined temperature. 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 water heater for the human body heating device 10, but may also be provided as a water heater shared with 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 member 60, the water heater 40 may be installed in that 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 of lead-in pipe 410 is connected to water heater 40 . The other end side of lead-in pipe 410 is connected to a position in the bottom surface of hot water storage container 100 near one end along the longitudinal direction.

The end of lead-in pipe 410 that is connected to hot water storage container 100 as described above is hereinafter also referred to as "first end 411". The first end portion 411 protrudes from the bottom surface of the hot water storage container 100 toward the inside of the hot water storage container 100 , and has an opening 412 at its tip that serves as an inlet for hot water drawn from the hot water storage container 100 . Thus, the first end 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, specifically, the side wall surface on the short side near which the first end 411 is arranged, will be hereinafter referred to as In this case, it is also written 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 an arrow AR1. This direction is a direction inclined 45 degrees with respect to the normal direction of the wall surface 101 when viewed from above, and is a direction toward the longer side where the first end 411 is arranged closer.

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

The end of the supply pipe 420 connected to the hot water storage container 100 as described above is hereinafter also referred to as a "second end 421". 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 is formed at the tip of the second end 421 as an outlet for hot water supplied to the hot water storage container 100 . . Thus, the second end 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, specifically, the side wall surface on the short side near which the second end 421 is arranged, is hereinafter referred to as In this case, it is also written 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 an arrow AR2. This direction is a direction inclined 45 degrees with respect to the normal direction of the wall surface 102 in top view, and is a direction away from the longer side where the second end 421 is arranged closer.

The human body heating device 10 further comprises a drain line 510 and an overflow line 520 .

The drain 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 drain pipe 510 is connected from below to a drain hole 512 formed in the bottom of the hot water storage container 100 . The other end of the drain pipe 510 is connected to a drain pipe (not shown) provided in the building. A solenoid valve 513 is provided in the middle of the drain pipe 510 . The solenoid valve 513 is a valve that can be switched between opening and closing in response to a signal from the outside. The electromagnetic valve 513 is closed during normal use of the human body heating device 10 . The opening/closing operation of the electromagnetic valve 513 is controlled by the controller 50, which will be described later.

The overflow pipe 520 is a pipe for discharging surplus 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 a predetermined water level. As shown in FIG. 4, the overflow pipe 520 is arranged to extend upward from the bottom of the hot water storage container 100, and has an upward opening 521 at its upper end. . 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 member 61 . In the portion below the hot water storage container 100 , each overflow pipe 520 is connected to a portion of the drain pipe 510 that is downstream of the solenoid valve 513 .

Reference numeral “WS” in FIG. 4 indicates 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 container 100 (that is, the height of the water surface WS) exceeds the opening 521 , part of the hot water flows into the overflow pipe 520 through the opening 521 . Therefore, the hot water level is always maintained at the same level as the height position of the opening 521 . The pair of overflow pipes 520 and the drain pipe 510 connected thereto correspond to a "water level maintenance section" 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 in which an opening 521 is formed at the predetermined water level.

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

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

At this time, the temperature of the hot water supplied from water heater 40 is set to the target hot water temperature transmitted from control device 50 to 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 43 to 45°C, for example.

After the hot water storage container 100 is completely filled with hot water and the hot water storage container 100 reaches the predetermined water level (the height of the opening 521), the human body heating device 10 is ready for use. A user can take a bedrock bath by lying down on the upper surface of the floor member 20.例文帳に追加

As described above, in the present embodiment, the hot water level (predetermined water level) 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. Also, the position of the opening 521 of the overflow pipe 520 is adjusted. Since the bottom portion of each floor member 20 is immersed in the hot water, it is directly heated by the hot water to raise its temperature. A 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 . This effectively raises the core body temperature of the human body.

Thus, the human body heating device 10 is configured such that the floor member 20 is heated by the heat of the hot water stored in the hot water storage container 100 . Such a human body heating apparatus 10 has a simple structure in which the upper side of the hot water storage container 100 is covered with the floor member 20, while the human body placed on the floor member 20 is heated by far infrared rays or the like, thereby recovering from fatigue. 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 techniques as those used when constructing a general bathtub can be used as they are. In other words, no special know-how or technique is required to install the human body heating device 10 according to the present embodiment, so that it can be easily installed by, for example, a worker at a plumbing shop.

Each floor member 20 is made of air-permeable lava. Therefore, water vapor is released upward through the numerous 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, an effect of relaxing the user can also be obtained.

As described above, in this 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 where the rock density is high and the porosity is low, the release amount of water vapor is suppressed, but the temperature of the floor member 22 tends to rise accordingly. As described above, in the human body heating apparatus 10 according to the present embodiment, the floor member 21 that releases a large amount of water vapor and the floor member 22 that easily increases in temperature are alternately arranged, thereby increasing the temperature of the human body. The balance between the amount of heating and the amount of steam is adjusted.

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

In other words, controller 50 adjusts the temperature of the hot water stored in hot water storage container 100 and maintains it at the target hot water temperature while circulating hot water between hot water storage container 100 and water heater 40 . The water heater 40 and the control device 50 correspond to a “hot water temperature adjustment unit” for adjusting the temperature of hot water stored in the hot water storage container 100 . Since the temperature of the hot water is kept 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, one supply pipe 420 is used both as a pipe for supplying hot water when filling with hot water and as a pipe for supplying hot water after the completion of filling with hot water. Instead of such a mode, a dedicated pipe for supplying hot water at the time of hot water filling may be provided separately from the supply pipe 420 .

The controller 50 and the water heater 40 included in the hot water temperature adjustment section adjust the temperature of the hot water stored in the hot water storage container 100 to a predetermined target hot water temperature as described above. This target hot water temperature is set by the control device 50 based on the user's operation on the operation unit 30 . The operation unit 30 and the control device 50 correspond to the "hot water temperature setting unit" in this embodiment. By changing the target hot water temperature as desired, the user can change the temperature of the hot water and, as a result, change the temperature of the floor member 20 .

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

In this embodiment, the first end 411 of the lead-in pipe 410 is arranged in the vicinity of the wall surface 101 on one side along the longitudinal direction of the hot water storage container 100 . Also, the second end 421 of the supply pipe 420 is arranged in the vicinity of the wall surface 102 on the other side along the longitudinal direction of the hot water storage container 100 .

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

In such a configuration, the hot water supplied from the opening 422 of the second end portion 421 to the hot water storage container 100 flows through substantially the entire hot water storage container 100 while turning clockwise when viewed from above, and then flows through the first hot water storage container 100 . It will be discharged from the opening 412 of the end portion 411 . This prevents the hot water stored in the hot water storage container 100 from being uneven in temperature, so that the plurality of floor members 20 as a whole can be heated substantially evenly.

After finishing the bedrock bath, the user operates the operation unit 30 to stop the operation of the water heater 40 . Based on the further investigation performed on the operation unit 30 , the control device 50 opens the electromagnetic valve 513 to discharge the hot water from the hot water storage container 100 .

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

A second embodiment will be described. This embodiment differs from the first embodiment in the configuration of some of the floor members 20 and the details of the processing performed by the control device 50 . In the following, points different from the first embodiment will be mainly described, and descriptions of points common to the first embodiment will be omitted as appropriate.

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

The recessed portion 23 is formed at the center of the floor member 20 when viewed from above. Also, the depth of the recess 23 is half 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 this embodiment, the user can set a target floor temperature, which is a target value for the temperature of the floor member 20 , by operating the operation unit 30 . The target bed temperature is preferably set in the range of 43 to 45°C, for example. During the operation of the human body heating apparatus 10, the controller 50 controls the operation of the water heater 40 so that the temperature of the floor member 20 measured by the temperature sensor 24 reaches the target floor temperature. 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. Conversely, 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 lowered. 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 on the operation unit 30 . The operation unit 30 and the control device 50 correspond to the "bed temperature setting unit" in this embodiment. Also in this embodiment, the user can change the temperature of the hot water by changing the target floor temperature as desired, thereby changing the temperature of the floor member 20 . In this embodiment, the user directly sets the target value for the temperature of the floor member 20, so that the user can be provided with a more comfortable bedrock bath.

The present embodiment has been described above with reference to specific examples. However, the present disclosure is not limited to these specific examples. Design modifications to these specific examples by those skilled in the art are also included in the scope of the present disclosure as long as they have the features of the present disclosure. Each element included in each specific example described above and its arrangement, conditions, shape, etc. are not limited to those illustrated and can be changed as appropriate. As long as there is no technical contradiction, the combination of the elements included in the specific examples described above can be changed as appropriate.
