Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the prior art, although it is possible to make the cold air flow along the inclined portion to the tip of the inclined portion, the cold air may constantly hit the head of the bed user, which may rather impair the comfort of the bed user. Therefore, it is conceivable to extend the return plate (inclined portion) in the prior art so as to cover the head of the bed user, thereby preventing the cold air from continuously hitting the head of the bed user. However, simply extending the plate may cause the space below the counter to be shaded, resulting in a space with low illuminance. And if the space below the counter becomes a space with low illuminance, it will be difficult for indoor lighting and natural light from outdoors to reach, and there is a concern that it will be difficult to get up in the morning.

[0005] The present invention has been made in view of the above circumstances, and its object is to form a comfortable thermal environment in the room space by using the air whose temperature is adjusted by the radiant air conditioner, and to form a sleep environment that is easy to get up from the viewpoint of illuminance.

Means for Solving the Problems

[0006] The invention according to claim 1 is, for example, an air conditioning system for a room space 1 as shown in FIGS. 22 to 24, etc., constituting the room space 1 A plurality of a wall portion 4(5), a radiant air conditioner 12 incorporated in and supported by the wall portion 4 and radiating heat from the wall surface of the wall portion 4, In the room space 1 where the radiant heating and cooling device 12 is incorporated and supported, with the bedding 10 arranged in a state where one end where the user's head is located is placed close to one of the plurality of wall portions 4(5), the counter is located above the bedding and above the user's head. Further, counters 49, 53, 55 attached to the wall portion 4 and protruding forward from the wall surface of the wall portion 4, On the counters 49, 53, 55,

Figure 1

[0007] According to the invention described in claim 1, since the radiant heating and cooling device 12 is incorporated and supported in the wall portion 4 to which the counters 49, 53, 55 are attached, not only can the objects located in the vicinity be heated or cooled by the direct radiant heat from the radiant heating and cooling device 12, but also the air (cold air) whose temperature is adjusted by the radiant heating and cooling device 12 at a position above the counters 49, 53, 55 can be made to descend from the protruding direction side end along the upper surface of the counters 49, 53, 55, or the air (warm air) whose temperature is adjusted by the radiant heating and cooling device 12 at a position below the counters 49, 53, 55 can be retained on the lower surface of the counters 49, 53, 55 so as not to let the air escape. Thereby, a comfortable thermal environment can be formed in the room space 1 by utilizing the air whose temperature is adjusted by the radiant heating and cooling device 12. Furthermore, since the counters 49, 53, 55 are provided with illuminance increasing means 50, 51, 54, 56 for increasing the illuminance in the space below the counters 49, 53, 55, even if the space below the counters 49, 53, 55 becomes a space with low illuminance due to being in the shade of the counters 49, 53, 55, the space below the counters 49, 53, 55 can be brightened by the illuminance increasing means 50, 51, 54, 56. Thereby, a sleep environment (waking-up environment) that is easy to wake up from the viewpoint of illuminance can be formed.

[0008] The invention described in claim 2 is, for example, as shown in FIG. 22, in the air conditioning system of the room space 1 described in claim 1, The illuminance increasing means 50, 51 are characterized in that they are lighting devices 50, 51 provided on the lower surface side of the counter 49.

[0009] According to the invention described in claim 2, since the illuminance increasing means 50, 51 are lighting devices 50, 51 provided on the lower surface side of the counter 49, as a dedicated device having the function of brightening the illuminated portion, the space below the counters 49, 53, 55 can be directly brightened. Thereby, it becomes easier to form a sleep environment that is easy to wake up from the viewpoint of illuminance.

[0010] The invention according to claim 3 is, for example, as shown in FIG. 22, in the air conditioning system of the room space 1 according to claim 2, the counter 49 has a lighting storage portion 52 for storing the lighting device 51 and arranging the lighting device 51 below the lower surface of the counter 49, characterized in that a gap is formed between the lower surface of the counter 49 and the lighting storage portion 52.

[0011] According to the invention of claim 3, the counter 49 has a lighting storage portion 52 for storing the lighting device 51 and arranging the lighting device 51 below the lower surface of the counter 49, and a gap is formed between the lower surface of the counter 49 and the lighting storage portion 52. Therefore, the space below the counters 49, 53, 55 can be brightened by the light leaking from the gap. That is, the lighting device 51 stored in the lighting storage portion 52 can function as indirect lighting, so that, unlike the case of being illuminated by directly visible light, the space below the counter 49 can be illuminated with soft light reflected on the lower surface of the counter 49 or the like.

[0012] The invention according to claim 4 is, for example, as shown in FIG. 23, in the air conditioning system of the room space 1 according to claim 1, the illuminance increasing means 54 is a monitor 54 provided on the lower surface of the counter 53 for displaying an image, and is characterized by this.

[0013] According to the invention of claim 4, since the illuminance increasing means 54 is a monitor 54 provided on the lower surface of the counter 53 for displaying an image, the space below the counter 53 can be brightened while displaying an image. As a result, it becomes easier to form a sleep environment in which it is easy to wake up from the viewpoint of illuminance. Furthermore, depending on the image to be displayed, it is possible to eliminate the sense of oppression caused by the presence of the counter 53 for the user P who uses the space below the counter 53.

[0014] The invention according to claim 5 is, for example, as shown in FIG. 24, in the air conditioning system of the room space 1 according to claim 1, the illuminance increasing means 56 is a mirror 56 provided in an inclined state on the lower surface of the counter 55, the mirror 56 is characterized in that the mirror surface is arranged on the side opposite to the wall portion 4 and obliquely downward.

[0015] According to the invention described in claim 5, the mirror 56 provided in an inclined state on the lower surface of the counter 55 is arranged such that the mirror surface is on the side opposite to the wall portion 4 and obliquely downward. Therefore, for the user P using the space below the counter 55, the light taken in from the outside of the space below the counter 55 will reach. As a result, if the room space 1 is darkened at bedtime, it is difficult for light to reach the user P using the space below the counter 55. However, in the morning, the natural light shining into the room space 1 from the outside will easily reach the user P using the space below the counter 55, so it is easier to form a sleep environment that is easy to get up from the perspective of illuminance. Furthermore, the user P using the space below the counter 55 can see the outside of the space below the counter 55 through the mirror 56, so it is possible to relieve the sense of oppression caused by the presence of the counter 55 on the user P using the space below the counter 55.

Effect of the Invention

[0016] According to the present invention, it is possible to form a comfortable thermal environment in the room space by using the air whose temperature is adjusted by the radiant air conditioner, and to form a sleep environment that is easy to get up from the perspective of illuminance.

Mode for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, although various technically preferable limitations are imposed on the embodiments described below for carrying out the present invention, the technical scope of the present invention is not limited to the following embodiments and illustrated examples. In addition, the embodiments described below may be combined as much as possible.

[0019] <First Embodiment> In FIG. 1, reference numeral 1 indicates a room space. This room space 1 is the internal space of a room where bedding 10 is installed, such as a master bedroom (bedroom), a children's room, or a living room in a house. The room space 1 is surrounded and formed by a floor portion 2, a ceiling portion 3, and a plurality of wall portions 4.

[0020] The floor portion 2 is provided continuously with the floor body on the same floor in the house. In the present embodiment, it is provided integrally with the floor body on the same floor, but it may be integrally formed with the floor body on the same floor. The floor portion 2 in the present embodiment is set to have the same height over the entire surface, but there may be stepped portions such as a skip floor, a small rise, or a dug floor. Note that a covering such as a tile carpet for preventing damage to the upper surface of the floor portion 2 by the legs of the bedding 10 may be laid.

[0021] The ceiling portion 3 is located above the floor portion 2 and is provided so as to have the same ceiling height as other rooms such as living rooms in the house. However, this does not apply in the case of a void or a low-ceiling room such as a loft. In this embodiment, the ceiling portion 3 has the entire surface set at the same height, but a sloped ceiling or a folded-up ceiling may also be used.

[0022] The plurality of wall portions 4 are arranged between the floor portion 2 and the ceiling portion 3, partitioning the room space 1 from other rooms or the outdoors. Further, the plurality of wall portions 4 may be provided continuously with the wall bodies forming other rooms in the house. Furthermore, the plurality of wall portions 4 may be provided as the inner walls inside the house, or may be provided as the outer walls constituting the outer periphery of the house. Among the plurality of wall portions 4, at least one wall portion 4 is formed with an entrance / exit opening (not shown) for entering and exiting the room space 1. Further, an opening (not shown) communicating with the outdoors may be formed in the plurality of wall portions 4.

[0023] The room space 1 is provided with a bedding 10 and a radiant heating and cooling device 12.

[0024] In this embodiment, the bedding 10 is a bed that supports the user P by positioning the user P's head on one end portion 10a side and the feet on the other end portion 10b side. The bed 10 is in a state where a mattress is provided on the base body. Hereinafter, the upper surface of the bed shall refer to the upper surface of the mattress. The thickness of the mattress can be changed as appropriate. Also, a pillow, a comforter, etc. may be appropriately used in combination with the bed 10.

[0025] And the bed 10 is installed in the room space 1 with one end portion 10a where the user P's head is located close to one of the plurality of wall portions 4. In other words, the first wall portion 4a can be used instead of a headboard. Among the wall surfaces of the first wall portion 4a, the portion where the bed 10 is brought close may be finished differently (such as wallpaper) from the surrounding of the portion, so that it can be easily determined that it can be used instead of a headboard. Also, the bed 10 may be fixed to the floor portion 2 or the wall portion 4. That is, a built-in bed 10 may also be used.

[0026] Note that the plurality of wall portions 4 include a first wall portion 4a arranged in a state where one end portion 10a of the bed 10 is brought closer, a second wall portion 4b orthogonal to the first wall portion 4a in a plan view, and other wall portions (not shown).

[0027] As the bedding 10, in addition to the bed 10, a futon, a hammock, a sleeping bag, etc. may be adopted. In any case, it is assumed that one end portion 10a where the head of the user P is located is installed in a state of being brought closer to one of the plurality of wall portions 4. A small rise may be provided on the floor portion 2, and a futon may be laid on the upper surface of the small rise and used in the same manner as the bed 10.

[0028] The radiant heating and cooling device 12 is a device that circulates a high-temperature or low-temperature fluid through the internal pipe material 13a and radiates heat from the surface, and is incorporated and supported in the first wall portion 4a arranged in a state where one end portion 10a of the bed 10 is brought closer. As the fluid, for example, water or antifreeze (e.g., ethylene glycol, etc.) is used. Water is easy to heat and cool and is also a suitable fluid for maintenance of piping and the like. Note that the first wall portion 4a in which the radiant heating and cooling device 12 is incorporated functions as a support for supporting the radiant heating and cooling device 12. The radiant heating and cooling device 12 may be incorporated in the second wall portion 4b. In that case, the second wall portion 4b also functions as a support. Also, in the present embodiment, the wall portion 4 is assumed to incorporate the radiant heating and cooling device 12, but it is not limited thereto, and the radiant heating and cooling device 12 may be incorporated in the floor portion 2 or the ceiling portion 3. That is, these floor portion 2 and ceiling portion 3 may function as supports, or alternatively, after all, the wall portion 4 may be used as a support and the radiant heating and cooling device 12 may be incorporated in the floor portion 2 or the ceiling portion 3.

[0029] The radiant heating and cooling device 12 is incorporated in the first wall portion 4a as described above and is in an integrated state. Therefore, the first wall portion 4a may refer to a component including the wall body of the first wall portion 4a and this radiant heating and cooling device 12. Therefore, the bed 10 is provided along such a radiant heating and cooling device 12. Note that although the first wall portion 4a is in a state without an opening, it only refers to the state without an opening in the range where the radiant heating and cooling device 12 is provided. An opening may be formed in a portion where the radiant heating and cooling device 12 is not provided. Also, in order to easily determine that the radiant heating and cooling device 12 is incorporated in the first wall portion 4a, the finish such as wallpaper may be made different from that of the other wall portions among the plurality of wall portions 4.

[0030] The radiant heating and cooling device 12 is disposed above the upper surface of the bed 10 in the first wall portion 4a. If it is disposed below the upper surface of the bed 10, condensation may occur due to the temperature difference from the mattress. Therefore, it is desirable that the radiant heating and cooling device 12 be disposed above the upper surface of the bed 10. By changing the mattresses used for the bed 10 to those with different thicknesses, the height position of the upper surface of the bed 10 can be changed. Therefore, in order to dispose the radiant heating and cooling device 12 above the upper surface of the bed 10, it is possible to cope with it using the mattress. Alternatively, the bed main body of the bed 10 may have a height adjustment function.

[0031] Regarding the configuration of the radiant heating and cooling device 12, in more detail, it includes a plurality of heating and cooling panels 13 in which pipes 13a through which cold water or warm water flows are piped inside, and a plurality of circulation pipes for circulating cold water or warm water between the heating and cooling panels 13 and a water supply source. The circulation pipes connect the plurality of heating and cooling panels 13 and the water supply source through, for example, under the floor or in the ceiling space. Note that the water supply source is connected to a heat exchange unit, and the heat exchange unit can circulate cold water in summer and warm water in winter to the radiant heating and cooling device 12. Also, if the plurality of heating and cooling panels 13 are each supplied with fluid in a different system, different temperature adjustment for each heating and cooling panel 13 becomes possible.

[0032] When incorporating such a radiant heating and cooling device 12 into the first wall portion 4a, a plurality of heating and cooling panels 13 are incorporated into the housing that constitutes the first wall portion 4a. That is, if the housing of a house having a room space 1 is, for example, of a conventional construction method, the first wall portion 4a is constituted by columns, beams, etc. The plurality of heating and cooling panels 13 may be directly attached to and incorporated into the housing such as columns and beams, or may be attached to a frame fixed to the housing. Further, although the plurality of wall portions 4 are filled with heat insulating materials, the plurality of heating and cooling panels 13 are provided adjacent to the heat insulating materials. If the housing of a house having a room space 1 is, for example, of a framed wall construction method, it is assumed that a plurality of heating and cooling panels 13 are incorporated between woods assembled in a frame shape. And the radiant heating and cooling device 12 incorporated into the housing that constitutes the first wall portion 4a is shielded by the facing material that constitutes the wall surface on the room space 1 side in the first wall portion 4a and is not exposed to the room space 1.

[0033] The user P can be warmed or cooled by the direct radiant heat from the radiant heating and cooling device 12. Therefore, when one end portion 10a of the bed 10 is arranged in a state of being close to the first wall portion 4a, the head of the user P located on the one end portion 10a side of the bed 10 is likely to be directly affected by the radiant heat from the radiant heating and cooling device 12, and the feet located on the other end portion 10b side of the bed 10 are less likely to be directly affected by the radiant heat from the radiant heating and cooling device 12.

[0034] Furthermore, the air near the radiant heating and cooling device 12 is temperature-adjusted by the radiant heat from the radiant heating and cooling device 12. And the temperature-adjusted air can warm or cool the inside of the room space 1 by natural convection in the room space 1. That is, if the user P is near the radiant heating and cooling device 12, they can be warmed or cooled by the direct radiant heat from the radiant heating and cooling device 12. Even if they are away from the radiant heating and cooling device 12, they can be warmed or cooled by the natural convection within the room space 1. In other words, if the air flow (air current) within the room space 1 can be controlled, the radiant heat emitted from the radiant heating and cooling device 12 can be carried further away.

[0035] In addition, although the radiant heating and cooling device 12 in this embodiment is incorporated and supported in the first wall portion 4a among the plurality of wall portions 4 constituting the room space 1, as shown in FIG. 2, it may be incorporated and supported in the recessed wall 5 formed on the wall surface of the first wall portion 4a. The recessed wall 5 includes a frame body (not shown) constituting the recessed wall 5, a facing material constituting the wall surface of the recessed wall 5 on the room space 1 side, and a heating and cooling panel 13 having a pipe 13a through which a high-temperature or low-temperature fluid flows. The heating and cooling panel 13 is provided on the back side of the facing material and supported by the frame body. As a result, the radiant heating and cooling device 12 is incorporated and supported in the recessed wall 5. Since the recessed wall 5 is formed on the wall surface of the first wall portion 4a and is arranged so as to project forward of the first wall portion 4a, if one end portion 10a of the bed 10 is brought close, it will be easily recognized by the user P as a headboard.

[0036] Also, as in the example shown in FIG. 2, by providing two recessed walls 5 (radiant heating and cooling devices 12) in the room space 1, it is possible to make the set temperature of the radiant heating and cooling device 12 in contact with one bed 10 (for example, the husband's bed) different from the set temperature of the radiant heating and cooling device 12 in contact with the other bed 10 (for example, the wife's bed). When the comfortable temperatures felt by the couple are different, the room temperature in the room space 1 may cause disputes. However, by installing a plurality of radiant heating and cooling devices 12, it is possible to achieve personal air conditioning that realizes the comfortable temperature for each user P, so it is possible to avoid such disputes.

[0037] And in the room space 1 configured as described above, an air conditioning system including a radiant heating and cooling device 12 is provided.

[0038] 〔Example〕 Hereinafter, the air conditioning system of the room space 1 in the present embodiment will be described in more detail. In each of the embodiments of the air conditioning system described below, it is assumed that the room space 1 has the configuration as described above. Also, for common elements, common reference numerals are given, and the description will be omitted or simplified as appropriate.

[0039] 〔Example 1-1〕 In the room space 1 of this example, as shown in FIG. 3, a first air flow control means 14 is provided on the side of the first wall portion 4a which is a support, and controls the flow of indoor air whose temperature is adjusted by the radiant heat from the radiant heating and cooling device 12 in a plurality of patterns.

[0040] More specifically, the first air flow control means 14 in this example is an air blowing device 14 having a function of blowing air toward the room space 1. In this example, it is assumed that a plurality of air blowing devices 14 are provided on the first wall portion 4a. And these plurality of air blowing devices 14 are arranged at intervals in the vertical direction.

[0041] Each air blowing device 14 is provided with an air outlet 14a for blowing air toward the room space 1. In each air blowing device 14, the main body for blowing air is arranged inside the wall of the first wall portion 4a, and only the air outlet 14a is exposed to the room space 1. The air outlet 14a can adjust the air volume and air speed by changing the wind direction in the vertical, horizontal directions, narrowing or widening the opening range. That is, although not shown in the figure, it is assumed that a plurality of fins for changing the wind direction and shutters for narrowing or widening the opening range are appropriately provided at the air outlet 14a. Such operations of the air outlet 14a may be automatically controlled or may be manually changeable. In addition, the main body of the air blowing device 14 can perform fundamental air volume adjustment. Further, the air blowing device 14 may have functions such as an on-timer and an off-timer. Note that there may be a remote control for controlling the operation of the air blowing device 14.

[0042] In this embodiment, the air outlet 14a is set to a width dimension corresponding to two beds 10 installed at intervals. However, it may be set to a width dimension corresponding to each bed 10, and the air outlet 14a (air blowing device 14) may be provided corresponding to each bed 10. That is, if the air outlet 14a (air blowing device 14) is arranged separately on the left and right, and the bed 10 is installed in front of these left and right air outlets 14a (air blowing device 14), the personalization will be enhanced. In other words, personal air conditioning that realizes a comfortable temperature for each user P using each of the left and right beds 10 becomes possible. When the radiant heating and cooling device 12 is provided on the fukashi wall 5, the air outlet 14a shall also be provided on the fukashi wall 5.

[0043] In addition, a plurality of radiant heating and cooling devices 12 in this embodiment are provided with respect to the first wall portion 4a. And these plurality of radiant heating and cooling devices 12 are arranged at intervals in the vertical direction. That is, a plurality of radiant heating and cooling devices 12 and a plurality of first air flow control means 14 are incorporated and supported on the first wall portion 4a. And the plurality of radiant heating and cooling devices 12 and the plurality of first air flow control means 14 are alternately arranged in the vertical direction. In the example shown in FIG. 3, a radiant heating and cooling device 12 is provided at the lowermost part, and a radiant heating and cooling device 12 is also provided at the uppermost part. Between these radiant heating and cooling devices 12, two radiant heating and cooling devices 12 and three air blowing devices 14 (air outlets 14a) are alternately provided.

[0044] The plurality of radiant heating and cooling devices 12 shall have the same fluid supply system and generate radiant heat at the same temperature. However, the set temperature may be changed for each of the radiant heating and cooling devices 12 arranged vertically.

[0045] The air conditioning system configured as described above can warm or cool those located in the vicinity by the direct radiant heat from the plurality of radiant heating and cooling devices 12. Also, the air near the plurality of radiant heating and cooling devices 12 will be temperature-adjusted by the radiant heat from the plurality of radiant heating and cooling devices 12. And the temperature-adjusted air can be sent by the plurality of air blowing devices 14, which are the first airflow control means, to a position far from or near the first wall portion 4a. Furthermore, by adjusting the wind direction and air volume for each of the plurality of air blowing devices 14 (air outlets 14a), it becomes possible to control the air flow in more diverse patterns. Thereby, the temperature-adjusted air can be circulated to various places within the room space 1. In addition to this, when changing the set temperature for each of the plurality of radiant heating and cooling devices 12 arranged vertically, it is possible to perform air conditioning control in a more complex pattern.

[0046] Among the plurality of patterns for controlling the flow of air temperature-adjusted by the radiant heat from the plurality of radiant heating and cooling devices 12 by the air blowing device 14, a pattern of stopping the operation of the air blowing device 14 may be included. That is, the air blowing device 14 can control the air flow in at least two patterns: operating or stopping.

[0047] Since one end portion 10a of the bed 10 is arranged close to the first wall portion 4a side, the user P of the bed 10 has their head warmed or cooled by the direct radiant heat from the radiant heating and cooling device 12. The feet of the user P located at the other end portion 10b of the bed 10 are less affected by the direct radiant heat from the radiant heating and cooling device 12, but will be warmed or cooled by the temperature-adjusted air sent by the air blowing device 14. That is, the air conditioning system in the room space 1 can contribute not only to the air conditioning of the entire room space 1 but also to the formation of a good sleeping environment in the bed 10 with one end portion 10a arranged close to the first wall portion 4a side.

[0048] In addition, although the first air flow control means 14 in this embodiment is the air blowing device 14, it is not limited thereto. For example, it may be a part of a ventilation device provided in a building, or an air conditioner that can adjust the temperature and humidity of the air in the room space 1. Also, in this embodiment, a plurality of air blowing devices 14 are provided, but one air blowing device 14 may be used. In that case, in order to control the air flow in the room space 1 in a plurality of patterns, there are a plurality of air outlets 14a, and these plurality of air outlets 14a and one air blowing device 14 are connected by a duct. Furthermore, since the air blowing device 14 is housed in the first wall portion 4a, when the first wall portion 4a (or the fukashi wall 5) is used as the headboard of the bed 10 and the user P uses it as a backrest, the air blowing device 14 does not get in the way.

[0049] 〔Embodiment 1-2〕 As shown in FIGS. 4 to 6, in the room space 1 of this embodiment, there is provided second air flow control means 15 that is arranged on the side of the first wall portion 4a that is a support and controls the flow of indoor air whose temperature is adjusted by the radiant heat from the radiant heating and cooling device 12 in a plurality of patterns.

[0050] More specifically, the second air flow control means 15 in this embodiment is a counter 15 provided to protrude from the wall surface of the first wall portion 4a. The counter 15 is provided at a height position above the upper surface of the bed 10. Also, the bed 10 is installed such that one end portion 10a is disposed below the counter 15. That is, the counter 15 is disposed above the head of the user P.

[0051] The counter 15 is constituted by a rectangular plate material, and the dimension in the longitudinal direction of the plate material is set to be substantially equal to the width dimension of the bed 10.

[0052] The counter 15 is provided so as to be movable in the vertical direction along the wall surface of the first wall portion 4a with respect to the wall surface of the first wall portion 4a. That is, a pair of guide rails 16 are provided on the wall surface of the first wall portion 4a, and support sliders 17 that slide along the guide rails 16 are provided on each of the pair of guide rails 16. It should be noted that the guide rail 16 is attached to the wall surface of the first wall portion 4a at a position where the lower end portion can be arranged at an interval upward from the upper surface of the bed 10.

[0053] Further, the counter 15 is provided between the support sliders 17 provided on the pair of guide rails 16 and is supported by these support sliders 17. In the present embodiment, among the horizontally arranged counters 15, the end portion on the first wall portion 4a side is connected to the support slider 17.

[0054] The support slider 17 can be temporarily fixed at an arbitrary position in the length direction of the guide rail 16. That is, the support slider 17 has a stopper (not shown) that contacts the guide rail 16. When the stopper is in contact with the guide rail 16, the support slider 17 is temporarily fixed at an arbitrary position in the length direction of the guide rail 16. Therefore, the counter 15 can be temporarily fixed at an arbitrary position in the length direction of the guide rail 16.

[0055] Further, the counter 15 is supported by the pair of support sliders 17 so as to be rotatable in the vertical direction and is configured to be angle-adjustable with respect to the wall surface of the first wall portion 4a. That is, when used as the counter 15, it is arranged in a state of protruding forward from the wall surface of the first wall portion 4a. However, since it is angle-adjustable, it can also be rotated upward or downward to be in a state along the wall surface of the first wall portion 4a. In this embodiment, the support slider 17 includes a slider body that slides along the guide rail 16, a fixing portion fixed to the side end surface of the counter 15, and an angle adjusting portion provided between the slider body and the fixing portion. The angle adjusting portion is configured (mechanism) to rotate the fixing portion with respect to the slider body in a side view and temporarily fix the rotation of the fixing portion at an arbitrary position in the rotation direction. A stopper may be provided as appropriate. However, it is not limited to this. The angle adjustment of the counter 15 with respect to the wall surface of the first wall portion 4a may be only two types of angles: the angle at which the counter 15 is horizontally arranged and the angle at which the counter 15 is rotated downward to be along the wall surface of the first wall portion 4a (in short, the folded state).

[0056] Note that, as shown in FIG. 5, articles such as a smartphone SP and an alarm clock AC are placed and used on the upper surface of the counter 15. However, if the counter 15 is rotated downward along the wall surface of the first wall portion 4a without noticing that an article is placed, the article will naturally fall. Therefore, a function of attaching an article is imparted to the upper surface of the counter 15. As the function of attaching an article, an adhesive sheet for repeatedly attaching an article and a magnet sheet for attaching a metal portion of the article are appropriately adopted. Also, like a hook-and-loop fastener, etc., not only on the upper surface side of the counter 15 but also on the article side, a part of the attaching function may be borne.

[0057] The vertical movement and angle adjustment of the counter 15 are performed automatically or manually. When performed automatically, as shown in FIG. 6, the second air flow control means 15 includes a drive unit 18 for automatically moving the counter 15 vertically and adjusting its angle. That is, the drive unit 18 has a first drive unit for sliding the support slider 17 along the guide rail 16 and a second drive unit for rotating the counter 15 with respect to the support slider 17.

[0058] The drive unit 18 is connected to a control device 19 constituted by a computer, either by wire or wirelessly, and is controlled by the control device 19. The control device 19 has a storage unit 20, and various programs and various data necessary for controlling the drive unit 18 are stored in the storage unit 20. Further, the control device 19 is configured to control the drive unit 18 according to the sensing result of a state detection sensor 21 provided in the room space 1.

[0059] Examples of the state detection sensor 21 include a sensor that detects the state of the air environment in the room space 1 such as temperature, humidity, and air cleanliness, a sensor that detects the illuminance under the counter 15, and a sensor that non - contactedly detects the biological information (body temperature, blood pressure, blood flow, heart rate, facial color, sleep, respiration, sweating, etc.) of the user P (which may include a camera or a microphone). That is, it is assumed that the various programs stored in the storage unit 20 of the control device 19 include a program that is executed when the sensing result of the state detection sensor 21 is input, and that operates the drive unit 18.

[0060] When the up - and - down movement and angle adjustment of the counter 15 are performed wirelessly, a communication network constructed in the building is used, and the drive unit 18, the control device 19, and the state detection sensor 21 are appropriately equipped with necessary communication modules and the like.

[0061] According to the automatic control system of the counter 15 configured in this way, when the sensing result by the state detection sensor 21 satisfies certain conditions, a predetermined program stored in the storage unit 20 of the control device 19 is executed, and the counter 15 can be slid along the guide rail 16 or rotated with respect to the support slider 17. Thereby, the up - and - down movement and angle adjustment of the counter 15 can be automatically performed.

[0062] When manually moving the counter 15 up and down and adjusting its angle, hold the counter 15 by hand and slide it upward or downward, or rotate it upward or downward. When the position of the counter 15 is determined, manually operate the stopper to temporarily fix the counter 15.

[0063] In the above manner, the counter 15 can be moved up and down or its angle can be adjusted. Such a counter 15 is attached to the first wall portion 4a via a guide rail 16, and the radiant heating and cooling device 12 is incorporated and supported therein.

[0064] In the air conditioning system of the room space 1 of the present embodiment, the objects located in the vicinity can be heated or cooled by the direct radiant heat from the radiant heating and cooling device 12. In addition, the air near the radiant heating and cooling device 12 will be temperature-adjusted by the radiant heat from the radiant heating and cooling device 12. Among the air temperature-adjusted by the radiant heating and cooling device 12, the air temperature-adjusted at a position above the counter 15 which is the second air flow control means will be less likely to flow directly below the counter 15. Furthermore, the air temperature-adjusted at a position below the counter 15 which is the second air flow control means will be less likely to flow directly above the counter 15. Moreover, by moving the counter 15 up and down and adjusting its angle, it becomes possible to control the air flow in more diverse patterns. In addition to this, when the set temperature of the radiant heating and cooling device 12 is changed, air conditioning can be controlled in a more complex pattern.

[0065] More specifically, the cooled air has the property of descending. The air temperature-adjusted at a position above the counter 15 is less likely to flow directly below the counter 15. Therefore, for a person who dislikes cold air hitting their face, the counter 15 can block the descending cold air as much as possible. The cold air blocked by the counter 15 will descend from the protruding direction side end (and the width direction side end) of the counter 15, so it will be easier to flow to the side of the user P's feet than the head. By setting the angle of the counter 15 to be downwardly inclined, the descending speed of the cold air can be improved. Conversely, by setting the angle of the counter 15 to be upwardly inclined, after retaining the descending cold air on the counter 15, it can be slowly descended from the protruding direction side end side or the first wall portion 4a side end side of the counter 15. Also, if the height position of the counter 15 is different, such air flow control will be different according to the height position. Furthermore, the air flow control will also be different depending on the set temperature of the radiant heating and cooling device 12.

[0066] On the other hand, the heated air has the property of rising. The air whose temperature is adjusted at a position below the counter 15 is less likely to flow directly above the counter 15. Therefore, for those who want to prevent warm air from escaping, the counter 15 can greatly suppress the escape of the rising warm air. The warm air whose temperature is adjusted at a position below the counter 15 gradually rises from the protruding direction side end of the counter 15. By setting the angle of the counter 15 to be downwardly inclined, it becomes easier to retain it under the counter 15. Conversely, by setting the angle of the counter 15 to be upwardly inclined, it becomes slightly easier to let the rising warm air escape. Also, if the height position of the counter 15 is different, such air flow control will be different according to the height position. Furthermore, the air flow control will also be different depending on the set temperature of the radiant heating and cooling device 12.

[0067] The counter 15 may include a pattern in which the counter 15 is rotated upward or downward to a state along the wall surface of the first wall portion 4a, as one of a plurality of patterns for controlling the flow of air temperature-adjusted by the radiant heat from the radiant air conditioner 12. That is, the counter 15 can control the air flow in at least two patterns: a state in which it protrudes perpendicularly from the wall surface of the first wall portion 4a, or a state in which it is folded and arranged along the wall surface of the first wall portion 4a.

[0068] The air conditioning system of the room space 1 of the present embodiment as described above can contribute not only to the air conditioning of the entire room space 1 but also to the formation of a good sleeping environment in the bed 10 with one end portion 10a arranged closer to the first wall portion 4a side.

[0069] Note that only one counter 15 is provided in the present embodiment, but a plurality of counters 15 may be provided at intervals in the vertical direction. In that case, by making the protruding dimensions from the first wall portion 4a of the plurality of counters 15 different, it becomes possible to control the air flow in more diverse patterns.

[0070] Furthermore, since the counter 15 can slide in the vertical direction, when the first wall portion 4a (or the fukashi wall 5) is used as the headboard of the bed 10 and the user P uses it as a backrest, sliding the counter 15 upward will not be obstructive.

[0071] 〔Example 1-3〕 In the room space 1 of the present embodiment, as shown in FIG. 7, third air flow control means 22 is provided which is arranged on the side of the first wall portion 4a serving as a support and controls the flow of indoor air temperature-adjusted by the radiant heat from the radiant air conditioner 12 in a plurality of patterns.

[0072] More specifically, the third airflow control means 22 in this embodiment is a sheet material 22 suspended from the ceiling portion 3 by wire materials 22a and 22b. The sheet material 22 is provided at a height position above the upper surface of the bed 10. Also, the bed 10 is installed such that one end portion 10a is disposed below the sheet material 22. That is, the sheet material 22 is disposed above the head of the user P.

[0073] The material (fabric) of the sheet material 22 is not selected to be, for example, something close to a "mesh" shape with a coarse texture that allows a large amount of air to pass through, in terms of controlling the airflow. Also, in order to suppress the sense of compression, it is preferable that the transparency or translucency is high, but it is not necessarily required to be high. In addition to this, if it flutters greatly when receiving wind, it becomes difficult to control the airflow, so it is preferably a material with a certain degree of weight. The sheet material 22 used as the third airflow control means preferably satisfies such conditions. However, it is not limited to this, and it can be appropriately changed according to the preference of the user P, such as a sheet material 22 with a pattern or a sheet material 22 made of a material that is easy to wash.

[0074] Also, the sheet material 22 is formed in a rectangular shape, and wire materials 22a and 22b are connected to the four corners. Each of the wire materials 22a and 22b has an upper end portion connected to a winding device (not shown). The winding device rotates automatically or manually, and can wind up or pay out the wire materials 22a and 22b as it rotates. Among the sheet material 22, the wire material 22a connected to the two corner portions on the side of the first wall portion 4a is hereinafter referred to as the first wire material 22a, and the wire material 22b connected to the two corner portions on the side opposite to the first wall portion 4a is hereinafter referred to as the second wire material 22b. Note that the first wire material 22a and the second wire material 22b are detachably connected to the four corners of the sheet material 22.

[0075] Since the four corners of the sheet material 22 are suspended by the first wire material 22a and the second wire material 22b, the portions other than the four corners are in a state of sagging downward. In addition, a bar may be passed between each of the two corners to which the first wire 22a is connected and between the two corners to which the second wire 22b is connected in the sheet material 22, so that the edge on the first wall portion 4a side (one side edge) and the edge on the opposite side (the other side edge) of the sheet material 22 do not bend.

[0076] The sheet material 22, which is the third airflow control means configured as described above, can be moved up and down and its angle adjusted by winding and unwinding the first wire 22a and the second wire 22b by the above-described winding device. That is, by unwinding and stretching the first wire 22a and the second wire 22b to make them long, or conversely, pulling them in by hand to shrink them, the sheet material 22 can be moved up and down. Also, by unwinding and stretching either the first wire 22a or the second wire 22b, or conversely, pulling it in by hand to shrink it, the angle of the sheet material 22 can be adjusted.

[0077] Note that the up and down movement and angle adjustment of the sheet material 22 are performed automatically or manually. When performed automatically, the winding device includes a drive unit for rotating the rotating body around which the first wire 22a and the second wire 22b are wound. This drive unit can be controlled with the same configuration as the above-described automatic control system (see FIG. 6). That is, the drive unit is connected to a control device constituted by a computer by wire or wirelessly, and is controlled by the control device according to a program stored in the storage unit. Also, the control device is configured to control the drive unit according to the sensing result of the state detection sensor 21 provided in the room space 1. According to the automatic control system of the sheet material 22 configured in this way, when the sensing result by the state detection sensor 21 satisfies certain conditions, a predetermined program stored in the storage unit of the control device is executed, and the first wire 22a and the second wire 22b can be appropriately wound and unwound by the winding device. As a result, the one side edge of the sheet material 22 can be raised or lowered, and the other side edge can be raised or lowered, so that the up and down movement and angle adjustment of the sheet material 22 can be performed automatically.

[0078] When manually moving the sheet material 22 up and down and adjusting its angle, the winding device is used as a fixed pulley fixed to the ceiling portion 3, and the ends of the first wire 22a and the second wire 22b wound around the rotating body of the winding device are hung downward. Rods are provided as weights on one side edge and the other side edge of the sheet material 22. Further, if fasteners are attached to the middle portions of the first wire 22a and the second wire 22b, the sheet material 22 will be arranged at a certain height, and its position can be set to the lowest position. When raising the sheet material 22, the ends of the first wire 22a and the second wire 22b hung downward may be pulled downward. Also, when temporarily fixing the sheet material 22 at the raised position, for example, the first wire 22a and the second wire 22b are tied to the hanging portion protruding from the first wall portion 4a.

[0079] In the above manner, the sheet material 22 can be moved up and down and its angle can be adjusted. In the first wall portion 4a where such a sheet material 22 is arranged in the front, the radiant heating and cooling device 12 is incorporated and supported.

[0080] In the air conditioning system of the room space 1 of the present embodiment, the objects located in the vicinity can be heated or cooled by the direct radiant heat from the radiant heating and cooling device 12. Also, the air near the radiant heating and cooling device 12 will be temperature-adjusted by the radiant heat from the radiant heating and cooling device 12. Among the air temperature-adjusted by the radiant heating and cooling device 12, the air temperature-adjusted at a position above the sheet material 22 which is the third air flow control means is less likely to flow directly below the sheet material 22. Further, the air temperature-adjusted at a position below the sheet material 22 which is the third air flow control means is less likely to flow directly above the sheet material 22. Moreover, by moving the sheet material 22 up and down and adjusting its angle, the air flow can be controlled in a more diverse pattern. In addition to this, when changing the set temperature of the radiant heating and cooling device 12, the air conditioning can be controlled in a more complex pattern.

[0081] More specifically, the cooled air has the property of descending. The air whose temperature is adjusted above the seat member 22 is less likely to flow directly below the seat member 22. Therefore, for a person who dislikes cold air hitting the face, the seat member 22 can block the descending cold air as much as possible. Since the seat member 22 is not attached to the first wall portion 4a, the cold air blocked by the seat member 22 will descend from the peripheral edge of the seat member 22. The cold air descending from the other side edge of the seat member 22 is more likely to flow towards the foot side of the user P than towards the head side. By inclining the seat member 22 downward (the other side edge is lower than one side edge), the descending speed of the cold air towards the foot side of the user P can be improved. Conversely, by inclining the seat member 22 upward (the other side edge is higher than one side edge), the descending speed of the cold air towards the head side of the user P can be improved. Also, if the height position of the seat member 22 is different, such air flow control will be different according to the height position. Furthermore, the air flow control also varies depending on the set temperature of the radiant heating and cooling device 12.

[0082] On the other hand, the warmed air has the property of rising. The air whose temperature is adjusted below the seat member 22 is likely to rise along the deflection of the seat member 22 and is less likely to stay below the seat member 22. When it is desired to retain warm air below the seat member 22, a pulling string (not shown) is connected to the center of the seat member 22, and after pulling the string upward, for example, the string is tied to a hook portion protruding from the first wall portion 4a. Thereby, the seat member 22 can be made to bulge upward, so that warm air can be retained below the seat member 22. Also, by inclining the seat member 22 downward or upward, the warm air retained below the seat member 22 can be gradually released upward. In addition, if the height position of the sheet material 22 is different, such control of the air flow will be different according to the height position. Furthermore, the control of the air flow also differs depending on the set temperature of the radiant heating and cooling device 12.

[0083] The air conditioning system of the room space 1 in the present embodiment as described above can contribute not only to the air conditioning of the entire room space 1 but also to the formation of a good sleeping environment in the bed 10 with one end 10a placed close to the first wall portion 4a.

[0084] Note that although only one sheet material 22 is provided in the present embodiment, a plurality of sheet materials 22 may be provided. In that case, by making the areas of the plurality of sheet materials 22 different, it becomes possible to control the air flow in more diverse patterns.

[0085] Furthermore, since the sheet material 22 can move in the vertical direction, when the first wall portion 4a (or the fukashi wall 5) is used as the headboard of the bed 10 and the user P uses it as a backrest, moving the sheet material 22 upward will not be obstructive.

[0086] The sheet material 22 in the present embodiment is formed in a rectangular shape with wire materials 22a and 22b connected to the four corners, but it is not limited to this. It may be formed in other polygonal shapes such as a triangular shape or a pentagonal shape, with wire materials 22a and 22b connected to the respective corners. However, in any case, in order to ensure the function as the air flow control means, it is desirable that the side portions rather than the corners (corners) of the sheet material 22 are arranged along the wall surface of the first wall portion 4a.

[0087] 〔Example 1 - 4〕 In the room space 1 of the present embodiment, as shown in FIG. 8, a fourth air flow control means 23 is provided which is arranged on the side of the first wall portion 4a which is a support and controls the flow of indoor air whose temperature is adjusted by the radiant heat from the radiant heating and cooling device 12 in a plurality of patterns.

[0088] More specifically, the fourth air flow control means 23 in this embodiment is a curved counter 23 provided to protrude from the wall surface of the first wall portion 4a. The curved counter 23 is provided at a height position above the upper surface of the bed 10. Further, the bed 10 is installed such that one end portion 10a is disposed below the curved counter 23. That is, the curved counter 23 will be disposed above the head of the user P.

[0089] The curved counter 23 is formed to be curved so as to bulge downward in a side view, and the protruding direction side end portion on the side opposite to the first wall portion 4a is in an upward state. Also, it is set to be substantially equal to the width dimension of the bed 10.

[0090] The end portion of the curved counter 23 on the first wall portion 4a side is bridged over a plurality of support portions 24 provided at intervals from each other on the wall surface of the first wall portion 4a, and is connected via a rotating shaft portion. That is, the curved counter 23 is rotatably supported by a plurality of support portions 24, and is attached to the wall surface of the first wall portion 4a via these plurality of support portions 24. Thereby, the curved counter 23 is configured to be rotatable in the vertical direction for angle adjustment.

[0091] Note that the curved counter 23 in this embodiment is configured to be angle-adjustable, but it may be configured to be movable up and down in the same manner as the counter 15 described above.

[0092] The radiant heating / cooling device 12 is incorporated and supported in the first wall portion 4a to which the curved counter 23 as described above is attached.

[0093] In the air conditioning system of the room space 1 of this embodiment, the objects located in the vicinity can be heated or cooled by the direct radiant heat from the radiant heating / cooling device 12. In addition, the air near the radiant heating and cooling device 12 will be temperature-adjusted by the radiant heat from the radiant heating and cooling device 12. Among the air temperature-adjusted by the radiant heating and cooling device 12, the air temperature-adjusted at a position above the curved counter 23 which is the fourth air flow control means will be less likely to flow directly below the curved counter 23. Furthermore, the air temperature-adjusted at a position below the curved counter 23 which is the fourth air flow control means will be less likely to flow directly above the curved counter 23. Moreover, by adjusting the angle of the curved counter 23, it becomes possible to control the air flow in more diverse patterns. In addition to this, when the set temperature of the radiant heating and cooling device 12 is changed, air conditioning can be controlled in a more complex pattern.

[0094] To explain in more detail, the cooled air has the property of descending. The air temperature-adjusted at a position above the curved counter 23 is less likely to flow directly below the curved counter 23. Therefore, for a person who dislikes cold air hitting their face, the curved counter 23 can block the descending cold air as much as possible. The cold air blocked by the curved counter 23 will descend from the protruding direction side end (and the width direction side end) of the curved counter 23, so it will be easier to flow to the toe side rather than the head of the user P. By making the angle of the curved counter 23 downwardly inclined, the descending speed of the cold air can be improved. In particular, since the protruding direction side end is in the upward state as described above, depending on the descending speed of the cold air, the cold air can be vigorously sent far away. On the contrary, by making the angle of the curved counter 23 upwardly inclined, a large amount of the descending cold air can be retained on the curved counter 23. The cold air that has accumulated can be slowly descended from the protruding direction side end side or the first wall portion 4a side end side of the curved counter 23.

[0095] On the one hand, the heated air has the property of rising. The air whose temperature is adjusted at a position below the curved counter 23 is likely to rise along the curved shape of the curved counter 23 and is less likely to stay below the curved counter 23. In other words, the curved counter 23 has a shape that easily releases the warm air. By setting the angle of the curved counter 23 to an upward inclination, the warm air can be released upward more quickly.

[0096] The air conditioning system of the room space 1 of the present embodiment as described above can contribute not only to the air conditioning of the entire room space 1 but also to the formation of a good sleeping environment in the bed 10 with one end 10a arranged closer to the first wall portion 4a side.

[0097] Note that only one curved counter 23 is provided in the present embodiment, but a plurality of curved counters 23 may be provided. In that case, by making the protruding dimensions from the first wall portion 4a of the plurality of curved counters 23 different, it becomes possible to control the air flow in more diverse patterns.

[0098] 〔Embodiment 1-5〕 In the room space 1 of the present embodiment, as shown in FIG. 9, a fifth air flow control means 25 is provided which is arranged on the first wall portion 4a side which is a support, and controls the flow of indoor air whose temperature is adjusted by the radiant heat from the radiant heating and cooling device 12 in a plurality of patterns.

[0099] More specifically, the fifth air flow control means 25 in the present embodiment is a counter 25 provided so as to protrude from the wall surface of the second wall portion 4b to the front of the first wall portion 4a. The counter 25 is provided at a height position above the upper surface of the bed 10. Also, the bed 10 is installed such that one end 10a is arranged below the counter 25. That is, the counter 25 is arranged above the head of the user P.

[0100] The counter 25 is composed of a rectangular plate material, and the lower end portion is attached to the second wall portion 4b that is orthogonal to the first wall portion 4a in a plan view. The second wall portion 4b is formed with a storage recess 4c for storing the counter 25, and the lower end portion of the counter 25 is attached via a rotating shaft portion to the lower end portion of the side edge in the storage recess 4c. That is, the counter 25 is configured to rotate in the vertical direction about the rotating shaft portion at the lower end portion.

[0101] At the lowest position, the counter 25 abuts against the lower edge of the storage recess 4c and is in a horizontally arranged state. An auxiliary bracket (not shown) that contacts the wall surface of the second wall portion 4b like a cane may be attached to the lower surface of the counter 25. At the uppermost position, the counter 25 is in a state of being stored in the storage recess 4c. A latch lock (not shown) is provided between the lower surface of the counter 25 (a vertical surface during storage) and the wall surface of the second wall portion 4b so that the stored state can be maintained.

[0102] In the second wall portion 4b to which the counter 25 as described above is attached, the radiant heating and cooling device 12 is not incorporated, but in the first wall portion 4a that is orthogonal in plan view, the radiant heating and cooling device 12 is incorporated and supported.

[0103] In the air conditioning system of the room space 1 of the present embodiment, the objects located in the vicinity can be heated or cooled by the direct radiant heat from the radiant heating and cooling device 12. Also, the air near the radiant heating and cooling device 12 will be temperature-adjusted by the radiant heat from the radiant heating and cooling device 12. Among the air temperature-adjusted by the radiant heating and cooling device 12, the air temperature-adjusted at a position above the counter 25 which is the fifth air flow control means will be less likely to flow directly below the counter 25. Furthermore, the air temperature-adjusted at a position below the counter 25 which is the fifth air flow control means will be less likely to flow directly above the counter 25.

[0104] More specifically, the cooled air has the property of descending. The air whose temperature is adjusted at a position above the counter 25 is less likely to flow directly below the counter 25. Therefore, for a person who dislikes cold air hitting their face, the counter 25 can block the descending cold air as much as possible. The cold air blocked by the counter 25 will descend from the protruding-direction side end of the counter 25 (and the end on the toe side of the user P), so it is easier to flow to the toe side than the head of the user P.

[0105] On the other hand, the warmed air has the property of ascending. The air whose temperature is adjusted at a position below the counter 25 is less likely to flow directly above the counter 25. Therefore, for a person who wants to prevent warm air from escaping, the counter 25 can suppress the escape of the ascending warm air as much as possible.

[0106] The air-conditioning system of the room space 1 in this embodiment as described above can contribute not only to the air-conditioning of the entire room space 1 but also to the formation of a good sleeping environment in the bed 10 with one end 10a placed close to the first wall portion 4a.

[0107] The counter 25 in this embodiment can control the air flow in two patterns: either protruding vertically from the second wall portion 4b or being housed in the storage recess 4c and arranged along the wall surface of the second wall portion 4b. However, it may also be configured to be angle-adjustable. In that case, by adjusting the angle of the counter 25, it becomes possible to control the air flow in more diverse patterns.

[0108] Furthermore, since the counter 25 can be housed in the storage recess 4c of the second wall portion 4b, when the first wall portion 4a (or the curtain wall 5) is used as the headboard of the bed 10 and the user P uses it as a backrest, storing the counter 25 in the storage recess 4c will not be obstructive.

[0109] 〔Example 1-6〕 In the room space 1 of this embodiment, as shown in FIG. 10, there is provided sixth air flow control means 26 that is disposed on the side of the first wall portion 4a serving as a support and controls the flow of indoor air whose temperature is adjusted by radiant heat from the radiant heating and cooling device 12 in a plurality of patterns.

[0110] More specifically, the sixth air flow control means 26 in this embodiment is a counter 26 provided so as to protrude from the wall surface of the first wall portion 4a. The counter 26 is provided at a height position above the upper surface of the bed 10. Also, the bed 10 is installed such that one end portion 10a is disposed below the counter 26. That is, the counter 26 is disposed above the head of the user P.

[0111] The counter 26 is formed in a rectangular shape, and the dimension in the longitudinal direction is set to be substantially equal to the width dimension of the bed 10. Further, the counter 26 is formed in a hollow shape, and a heating and cooling panel 13 is provided in the hollow portion thereof. That is, the counter 26 functions as a radiant heating and cooling device.

[0112] The heating and cooling panel 13 provided in the hollow portion of the counter 26 is configured to receive fluid supply from a different system from the heating and cooling panel 13 that constitutes the radiant heating and cooling device 12 incorporated in and supported by the first wall portion 4a. Thereby, different temperature adjustments are possible between the counter 26 that functions as a radiant heating and cooling device and the radiant heating and cooling device 12 on the side of the first wall portion 4a.

[0113] Note that the heating and cooling panel 13 provided in the hollow portion of the counter 26 has a circulation pipe passing through the inside of the first wall portion 4a and connected to a water supply source. Therefore, the counter 26 in this embodiment is configured not to move up and down or adjust its angle.

[0114] In the air conditioning system of the room space 1 of this embodiment, the direct radiant heat from the radiant heating and cooling device 12 can warm or cool the objects located in the vicinity. Also, the direct radiant heat from the counter 26 functioning as a radiant heating and cooling device can warm or cool the objects located in the vicinity. Also, the air near the radiant heating and cooling device 12 and the counter 26 will be temperature-adjusted by the radiant heat from the radiant heating and cooling device 12 and the counter 26. And among the air temperature-adjusted by the radiant heating and cooling device 12 and the counter 26, the air temperature-adjusted at a position above the counter 26 becomes less likely to flow directly below the counter 26. Further, the air temperature-adjusted at a position below the counter 26 becomes less likely to flow directly above the counter 26.

[0115] In this embodiment, by appropriately changing the temperature adjustment (including on / off) by the radiant heating and cooling device 12 and the temperature adjustment (including on / off) by the counter 26 functioning as a radiant heating and cooling device, the air flow can be controlled.

[0116] More specifically, when only the radiant heating and cooling device 12 is operated in the cooling or heating mode, when only the counter 26 functioning as a radiant heating and cooling device is operated in the cooling or heating mode, when both the radiant heating and cooling device 12 and the counter 26 are operated in the cooling or heating mode, and when the temperature adjustment is performed separately and combined into an operating state, it is possible to control the air flow in various patterns without moving the counter 26 up and down or adjusting its angle.

[0117] The air conditioning system of the room space 1 of this embodiment as described above can contribute not only to the air conditioning of the entire room space 1 but also to the formation of a good sleeping environment in the bed 10 with one end portion 10a placed close to the first wall portion 4a.

[0118] 〔Embodiment 1-7〕 FIG. 11 shows an example of the arrangement of the airflow control means for a plurality of air-conditioning panels 13 in which the pipe material 13a is piped inside. The pipe material 13a is arranged in a meandering manner inside the air-conditioning panel 13. Note that at least a facing material (such as a building board like plywood or a fireproof covering material like gypsum board) that constitutes the wall surface of the first wall portion 4a is interposed between the plurality of air-conditioning panels 13 and the airflow control means.

[0119] The airflow control means shown in FIG. 11(a) is a counter 27 fixed to the wall surface of the first wall portion 4a, and is configured not to slide along the wall surface of the first wall portion 4a at least. When fixing such a counter 27 to the wall surface of the first wall portion 4a, the counter 27 itself or the bracket that supports the counter 27 is fixed to the facing material that constitutes the wall surface of the first wall portion 4a by a fixing material B such as a screw. At that time, as shown in FIG. 11(a), the fixing material B is driven in avoiding the meandering pipe material 13a.

[0120] The airflow control means shown in FIG. 11(b) is a counter provided so as to be vertically movable with respect to the wall surface of the first wall portion 4a, and the counter is slidably provided with respect to a pair of guide rails 28 arranged and fixed along the vertical direction on the wall surface of the first wall portion 4a. When fixing such a pair of guide rails 28 to the wall surface of the first wall portion 4a, the pair of guide rails 28 are fixed to the facing material that constitutes the wall surface of the first wall portion 4a by a fixing material B such as a screw. At that time, as shown in FIG. 11(b), the fixing material B is driven in avoiding the meandering pipe material 13a.

[0121] 〔Example 1-8〕 In this example, as shown in FIG. 12, a non-contact thermometer 30 for measuring the body temperature of the user P is adopted for the counter 29. In addition, a humidifying device 31 is provided on the counter 29, and it is possible to take measures against drying of the user P in winter. Note that the counter 29 in this example can be vertically moved and angle-adjusted as necessary.

[0122] A recess 29a is formed on the lower surface of the counter 29, and the non-contact thermometer 30 and the humidifying device 31 are housed and attached in the recess 29a. The non-contact thermometer 30 can be used not only for the health management of the user P but also as the above-described state detection sensor. The humidifying device 31 can be used not only for the health management of the user P and the countermeasure against dryness in winter but also as one function of the air conditioning system in the room space 1. That is, the humidity can be adjusted by operating the humidifying device 31. The humidifying device 31 is provided as a set with a tank 31a that can be removed from the recess 29a.

[0123] By thus providing the airflow control means with the health management function for the user P, as a result, it is possible to contribute not only to the air conditioning of the entire room space 1 but also to the formation of a good sleep environment in the bed 10 with one end portion 10a arranged closer to the first wall portion 4a side, which is preferable.

[0124] In the present embodiment, it is assumed that the non-contact thermometer 30 for measuring the body temperature of the user P is adopted for the counter 29. However, instead of the non-contact thermometer 30, a biosensor (which may include a camera and a microphone) that non-contact detects the biological information (body temperature, blood pressure, blood flow, heartbeat, complexion, sleep, respiration, sweating, etc.) of the user P may be adopted.

[0125] Further, in the present embodiment, it is assumed that the humidifying device 31 is provided for the counter 29. However, instead of the humidifying device 31 or together with the humidifying device 31, a dehumidifying device (not shown) may be provided. By providing the dehumidifying device, dehumidification in summer and during the rainy season can be performed, and thus it is possible to contribute to the formation of a good sleep environment.

[0126] According to the present embodiment, the following excellent effects can be obtained. That is, since the airflow control means 14, 15, 22, 23, 25, 26, 27, 29 control the airflow in the room space 1 in a plurality of patterns, it is possible to prevent the airflow from always becoming constant. As a result, the air temperature-adjusted by the radiant heat from the radiant heating and cooling device 12 can be widely circulated in the room space 1, so that a comfortable thermal environment can be formed in the room space 1.

[0127] Further, the air blowing device 14 that blows air from the air outlet 14a is incorporated in and supported by the support 4 and is arranged side by side with the radiant heating and cooling device 12. Therefore, the air temperature-adjusted by the radiant heat from the radiant heating and cooling device 12 can be easily and widely circulated in the room space 1 by the air blown out from the air outlet 14a of the air blowing device 14.

[0128] Further, the support 4 is the wall portion 4 that constitutes the room space 1, and the radiant heating and cooling device 12 and the air blowing device 14 are arranged side by side vertically. Therefore, the cold air having the property of descending or the warm air having the property of ascending can be easily and widely circulated in the room space 1 by the air blown out from the air outlet 14a of the air blowing device 14. That is, for example, if the air blowing device 14 is arranged below the radiant heating and cooling device 12, it is easy to widely circulate the cold air having the property of descending in the room space 1, and if the air blowing device 14 is arranged above the radiant heating and cooling device 12, it is easy to widely circulate the warm air having the property of ascending in the room space 1.

[0129] Further, since the airflow control means 15, 22, 23, 25, 26, 27, 29 are arranged in front of the support 4 and are configured to be position-changeable with respect to the surface of the support 4 on the room space 1 side, the air temperature-adjusted by the radiant heat from the radiant heating and cooling device 12 can be circulated in the room space 1 according to the position change of the airflow control means 15, 22, 23, 25, 26, 27, 29.

[0130] In addition, since the counters 15, 23, 25, 26, 27, 29 can be adjusted in angle with respect to the wall surface of the wall portion 4, the air whose temperature is adjusted by the radiant heat from the radiant heating and cooling device 12 can be circulated into the room space 1 according to the angles of the counters 15, 23, 25, 26, 27, 29.

[0131] In addition, since the counters 15, 23, 25, 26, 27, 29 can be moved in the vertical direction along the wall surface of the wall portion 4, the air whose temperature is adjusted by the radiant heat from the radiant heating and cooling device 12 can be circulated into the room space 1 according to the vertical positions of the counters 15, 23, 25, 26, 27, 29.

[0132] In addition, the counter 23 is formed to be curved so as to bulge downward in a side view, and the protruding direction side end portion located on the side opposite to the wall portion 4 is in an upward state. Therefore, by setting the angle of the counter 23 to a downward inclination, the cold air having a property of descending can be vigorously sent far away from the protruding direction side end portion in an upward state. Further, by setting the angle of the counter 23 to an upward inclination, the cold air having a property of descending can be easily retained more on the counter 23.

[0133] In addition, the airflow control means 15, 23, 25, 26, 27, 29 are directly or indirectly fixed to the surface of the support 4 on the room space 1 side by the fixing material B, and the fixing material B is arranged avoiding the pipe material 13a among the heating and cooling panels 13 in the radiant heating and cooling device 12 incorporated in the support 4. Therefore, the airflow control means 15, 23, 25, 26, 27, 29 can be arranged in front of the radiant heating and cooling device 12 while not damaging the pipe material 13a by the fixing material B.

[0134] In addition, the sheet material 22 suspended from the ceiling portion 3 and arranged in front of the wall portion 4 can be moved in the vertical direction along the wall surface of the wall portion 4 and can be adjusted in angle with respect to the wall surface of the wall portion 4. Therefore, the air whose temperature is adjusted by the radiant heat from the radiant heating and cooling device 12 can be circulated into the room space 1 according to the vertical position and angle of the sheet material 22.

[0135] In addition, since the control device 19 controls the operations of the airflow control means 15, 22, 23, 25, 26, 27, 29 according to the sensing results of the state detection sensor 21 provided in the room space 1, it is possible to perform optimal control according to the state of the room space 1, and a comfortable heating and cooling environment can be automatically formed in the room space 1.

[0136] <Second Embodiment> Next, the second embodiment will be described with reference to the drawings. For convenience of explanation, elements common to the above-described first embodiment are denoted by common reference numerals, and the description thereof is omitted or simplified.

[0137] The room space 1 in the present embodiment is the internal space of a room where a bedding 10 is installed, such as a master bedroom (bedroom), a children's room, or a living room in a house. The room space 1 is formed by being surrounded by a floor portion 2, a ceiling portion 3, and a plurality of wall portions 4. The room space 1 is provided with a bedding 10 and a radiant heating and cooling device 12. And an air conditioning system including the radiant heating and cooling device 12 is provided in the room space 1 configured as described above.

[0138] 〔Example〕 Hereinafter, the air conditioning system of the room space 1 in the present embodiment will be described in more detail. In each example of the air conditioning system described below, it is assumed that the room space 1 has the configuration as described above. In addition, common elements are denoted by common reference numerals, and the description thereof is appropriately omitted or simplified.

[0139] 〔Example 2-1〕 In order to form a comfortable enclosed space at the time of going to bed in the room space 1 of the present example, as shown in FIG. 13, a first covering body 32 is provided on the first wall portion 4a serving as a support and protruding from the wall surface of the first wall portion 4a.

[0140] The lower surface of the first covering body 32 is curved upward in a side cross-sectional view, and includes a first curved region 32b that gradually curves upward from the lower end portion 32d at the portion (base end portion) on the first wall portion 4a side and reaches the apex 32a as it goes toward the other end portion 10b side of the bed 10, and a second curved region 32c that gradually curves downward from the apex 32a and reaches the lower end portion 32e at the protruding direction side end portion (tip portion) as it goes toward the other end portion 10b side of the bed 10. Also, the lower end portion 32d at the base end portion of the first covering body 32 and the lower end portion 32e at the protruding direction side end portion (tip portion) of the first covering body 32 are at the same height position. In addition, when the lower surface of the first covering body 32 is formed in such a curved shape, it is preferable to set the apex 32a to be located above the head of the user P.

[0141] The portion (base end portion) on the first wall portion 4a side of the first covering body 32 is provided integrally with the first wall portion 4a. Also, the first covering body 32 is configured to be as lightweight as possible by adopting, for example, a honeycomb structure or a foam structure so as to ensure a long protruding dimension from the first wall portion 4a. Furthermore, the base end portion side may be configured to be solid so as to be firmly fixed to the first wall portion 4a, and the protruding direction side may be configured to be hollow so as to achieve weight reduction. For example, when adopting a honeycomb structure or a foam structure, it is preferable to use a hard paper material, thin wood, etc. as the material, which can contribute more to weight reduction.

[0142] The upper surface of the first covering body 32 is provided with a counter plate material 33 to form a horizontal plane, and an article can be placed on the upper surface. The counter plate material 33 is also configured to be as lightweight as possible by adopting, for example, a honeycomb structure or a foam structure.

[0143] Note that the first covering 32 in this embodiment is configured to be as lightweight as possible by adopting, for example, a honeycomb structure or a flash structure. However, it is not limited thereto, and a flexible material such as rubber or other synthetic resin may be adopted to give the first covering 32 flexibility.

[0144] By forming and providing the first covering 32 as described above, a trapped space can be secured within the room space 1. Note that side walls may be integrally provided at both ends in the width direction of the first covering 32 to enhance the isolation from the outside, or the side walls may be absent and in an open state.

[0145] The radiant heating and cooling device 12 is incorporated and supported on the first wall portion 4a to which the first covering 32 is attached. Note that the first covering 32 also functions as an air diffusion means for diffusing the indoor air temperature-adjusted by the radiant heat from the radiant heating and cooling device 12 to a farther place from the radiant heating and cooling device 12.

[0146] In the air conditioning system of the room space 1 of this embodiment, the direct radiant heat from the radiant heating and cooling device 12 can warm or cool the objects located nearby. Also, the air near the radiant heating and cooling device 12 will be temperature-adjusted by the radiant heat from the radiant heating and cooling device 12. Among the air temperature-adjusted by the radiant heating and cooling device 12, the air temperature-adjusted at a position above the first covering 32 is less likely to flow directly below the first covering 32. Further, the air temperature-adjusted at a position below the first covering 32 is less likely to flow directly above the first covering 32.

[0147] More specifically, the cooled air has the property of descending. Since the air temperature-adjusted at a position above the first covering 32 is less likely to flow directly below the first covering 32, the first covering 32 can block the descending cold air as much as possible for people who dislike cold air hitting their faces. The cold air blocked by the first covering 32 will descend from the protruding direction side end (and the width direction side end) of the first covering 32, so it will be easier to flow to the foot side than the head of the user P.

[0148] On the other hand, the warmed air has the property of rising. The air whose temperature is adjusted at a position below the first covering 32 is less likely to flow directly above the first covering 32. Therefore, for those who want to prevent warm air from escaping, the first covering 32 can extremely suppress the escape of the rising warm air. That is, since the warm air whose temperature is adjusted at a position below the first covering 32 is likely to stay on the curved lower surface of the first covering 32, the escape of the rising warm air can be extremely suppressed.

[0149] The air conditioning system of the room space 1 of the present embodiment as described above can contribute not only to the air conditioning of the entire room space 1 but also to the formation of a good sleeping environment in the bed 10 with one end portion 10a arranged close to the first wall portion 4a. In particular, since the portion from the lower end portion 32d at the base end portion to the lower end portion 32e at the tip end portion of the first covering 32 is curved upward in a side view (side cross-sectional view), for the user P with the head placed below it, the space can be widened upward. As a result, compared with the case where, for example, the portion from the lower end portion 32d at the base end portion to the lower end portion 32e at the tip end portion of the first covering 32 is a flat ceiling surface without curvature, it is less likely to feel a sense of compression. Therefore, a cage space that can appropriately cover the head of the user P can be formed.

[0150] Note that the first covering 32 in the present embodiment is configured not to move up and down or adjust the angle, but it is not limited to this. It may be provided so as to be movable in the vertical direction along the wall surface of the first wall portion 4a, or may be provided so as to be angle-adjustable with respect to the wall surface of the first wall portion 4a. Alternatively, the first covering 32 may be configured to be rotatable upward and angle-adjustable to a state along the wall surface of the first wall portion 4a (that is, a folded state).

[0151] Example 2-2 In the room space 1 of this example, as shown in FIG. 14, in order to form a comfortable enclosed space at bedtime, a second covering body 34 is provided on the first wall portion 4a serving as a support and protrudes from the wall surface of the first wall portion 4a.

[0152] The lower surface of the second covering body 34 is curved upward in a side cross-sectional view, and gradually curves upward from the lower end portion 34d at the portion (base end portion) on the first wall portion 4a side toward the other end portion 10b side of the bed 10 to reach the apex 34a, and from the apex 34a toward the other end portion 10b side of the bed 10, it gradually curves downward to reach the lower end portion 34e at the protruding direction side end portion (tip portion), and has a first curved region 34b and a second curved region 34c. Further, the lower end portion 34d at the base end portion of the second covering body 34 and the lower end portion 34e at the protruding direction side end portion (tip portion) of the second covering body 34 are at the same height position. When the lower surface of the second covering body 34 is formed in such a curved shape, it is preferable to set the apex 34a to be located above the head of the user P.

[0153] The portion (base end portion) of the second covering body 34 on the first wall portion 4a side is integrally provided with respect to the first wall portion 4a. In addition, the second covering body 34 adopts, for example, a honeycomb structure or a flush structure so as to ensure a long protruding dimension from the first wall portion 4a, and is configured to be as lightweight as possible. Furthermore, the base end portion side may be configured to be solid so as to be firmly fixed to the first wall portion 4a, and the protruding direction side may be configured to be hollow so as to achieve weight reduction. When adopting, for example, a honeycomb structure or a flush structure, it is preferable to use a hard paper material, a thin wood material, etc. as the material, which can contribute more to weight reduction.

[0154] The upper surface of the second covering 34 is formed to gradually curve downward from the first wall portion 4a side toward the tip end portion side. In other words, the upper surface of the second covering 34 gently slopes downward from the upper end portion at the portion (base end portion) on the first wall portion 4a side toward the end portion (tip end portion) on the protruding direction side.

[0155] By forming and providing the second covering 34 as described above, a trapped space can be secured within the room space 1. Note that side walls may be integrally provided at both ends in the width direction of the second covering 34 to enhance the isolation from the outside, or the second covering 34 may be in an open state without side walls.

[0156] A radiant heating and cooling device 12 is incorporated and supported on the first wall portion 4a to which the second covering 34 is attached. Note that the second covering 34 also functions as an air diffusion means for diffusing the indoor air temperature-adjusted by the radiant heat from the radiant heating and cooling device 12 to a farther place from the radiant heating and cooling device 12.

[0157] In the air conditioning system of the room space 1 of this embodiment, the objects located in the vicinity can be heated or cooled by the direct radiant heat from the radiant heating and cooling device 12. Also, the air near the radiant heating and cooling device 12 will be temperature-adjusted by the radiant heat from the radiant heating and cooling device 12. Among the air temperature-adjusted by the radiant heating and cooling device 12, the air temperature-adjusted at a position above the second covering 34 will be less likely to flow directly below the second covering 34. Further, the air temperature-adjusted at a position below the second covering 34 will be less likely to flow directly above the second covering 34.

[0158] More specifically, the cooled air has the property of descending. Since the air temperature-adjusted at a position above the second covering 34 is less likely to flow directly below the second covering 34, for those who dislike cold air hitting their faces, the second covering 34 can block the descending cold air as much as possible. The cold air blocked by the second covering 34 will descend from the protruding direction side end (and the width direction side end) of the second covering 34, so it will be easier to flow to the toe side of the user P's head. In particular, since the upper surface of the second covering 34 is gradually curved downward from the first wall portion 4a side toward the tip portion side, the cold air is more likely to flow to the toe side of the user P compared to the case where the upper surface is formed horizontally.

[0159] On the other hand, the warmed air has the property of rising. The air whose temperature is adjusted at a position below the second covering 34 is less likely to flow directly above the second covering 34. Therefore, for those who want to prevent the warm air from escaping, the second covering 34 can greatly suppress the escape of the rising warm air. That is, since the warm air whose temperature is adjusted at a position below the second covering 34 is likely to stay on the curved lower surface of the second covering 34, the escape of the rising warm air can be greatly suppressed.

[0160] The air conditioning system of the room space 1 of the present embodiment as described above can contribute not only to the air conditioning of the entire room space 1 but also to the formation of a good sleeping environment in the bed 10 with one end portion 10a placed closer to the first wall portion 4a side. In particular, since the portion from the lower end portion 34d at the base end portion to the lower end portion 34e at the tip end portion of the second covering 34 is curved upward in a side view (side cross-sectional view), for the user P with the head placed below it, the space can be expanded upward. As a result, for example, compared to the case where the portion from the lower end portion 34d at the base end portion to the lower end portion 34e at the tip end portion of the second covering 34 is a flat ceiling surface without curvature, it is less likely to feel a sense of compression. Therefore, a cage space that can appropriately cover the user P's head can be formed.

[0161] Note that although the second cover 34 in this embodiment is configured not to move up and down or adjust its angle, it is not limited to this. It may be provided so as to be movable in the vertical direction along the wall surface of the first wall portion 4a, or may be provided so as to be angle-adjustable with respect to the wall surface of the first wall portion 4a. Alternatively, the second cover 34 may be configured to be rotatable upward and angle-adjustable in a state along the wall surface of the first wall portion 4a (that is, in a folded state).

[0162] FIG. 15 shows an example in which a wall body 35 with lighting that can be used as a headboard of the bed 10 is provided in contact with the wall surface of the first wall portion 4a. This wall body 35 with lighting is erected on the floor portion 2 and fixed to the wall surface of the first wall portion 4a, but it is not limited to this. It may be integrally formed as a headboard on the base body of the bed 10.

[0163] The wall body 35 with lighting has a recess 35a formed at its upper end, and a lighting device 36 is provided in the recess 35a. The upper opening of the recess 35a is closed by a lid body 36a having translucency. Articles can be placed on the upper surface of the lid body 36a. The recess 35a is formed on the side of the first wall portion 4a of the rising portion 35b located on the bed 10 side. Thereby, the lighting device 36 provided in the recess 35a can emit light upward through the lid body 36a and illuminate the interior of the enclosed space as indirect lighting. That is, the light emitted from the lighting device 36 hits the lower surface of the second cover 34 to become soft light. As a result, the space below the second cover 34 has a reduced sense of oppression and becomes a calm space. In addition, since the lower surface of the second cover 34 is curved, the light illuminating the enclosed space is less likely to leak to the outside (foot side) from the end portion on the protruding direction side. Therefore, it is difficult for the light of the lighting device 36 to reach a person outside the second cover 34, which can also contribute to the formation of a good sleep environment for a person outside the second cover 34. Note that since the illumination device 36 enables adjustment of the illuminance in the lower space of the second covering 34, for example, by setting the illumination device 36 to emit light when waking up, the lower space of the second covering 34 can be brightened, contributing to the formation of a good waking-up environment.

[0164] Note that an acoustic device (speaker) that emits sound may be provided at the upper end of the wall body 35 with illumination, instead of or in combination with the illumination device 36. Also in the case of an acoustic device, sound is less likely to leak from the outer (toe side) of the protruding direction side end. Therefore, it is difficult for the sound from the acoustic device to reach a person outside the second covering 34, contributing to the formation of a good sleeping environment for a person outside the second covering 34. Also, by using the illumination device 36 and the acoustic device in combination, for example, by setting the illumination device 36 to emit light and the acoustic device to emit sound when waking up, it can play a role in assisting a comfortable waking-up.

[0165] 〔Example 2-3〕 In the room space 1 of this example, as shown in FIG. 16, in order to form a comfortable enclosed space at bedtime, a third covering 37 is provided on the first wall portion 4a which is a support body and protrudes from the wall surface of the first wall portion 4a.

[0166] Although not shown, the lower surface of the third covering 37 has a first curved region 37b that gradually curves upward from the lower end 37d at the portion (base end portion) on the first wall portion 4a side toward the other end 10b side of the bed 10 and reaches the apex 37a, and a second curved region that gradually curves downward from the apex 37a toward the other end 10b side of the bed 10 and reaches the lower end at the protruding direction side end (tip portion). Also, the upper surface of the third covering 37 is formed to gradually curve downward from the first wall portion 4a side toward the tip portion side.

[0167] And as shown in FIG. 16, both side end portions 37f in the width direction of the third covering 37 are in a state of being located below the above-mentioned apex 37a which is the highest portion on the lower surface of the third covering 37. More specifically, the lower surface of the third covering body 37 in this embodiment is curved upward in a vertical cross-sectional view, and gradually curves downward and slopes from the apex 37a toward both end portions 37f in the width direction. Both end portions 37f in the width direction are set at substantially the same height position as the lower end portion 37d at the base end portion of the third covering body 37 and / or the lower end portion at the tip end portion. As a result, since the lower surface of the third covering body 37 is formed in a dome shape in a side cross-sectional view and a vertical cross-sectional view, the space below the third covering body 37 is in a state where the isolation from the outside is enhanced.

[0168] Note that although the lower surface of the third covering body 37 in this embodiment is curved upward in a vertical cross-sectional view, it is not limited to this, and it may not be curved upward in a vertical cross-sectional view. That is, both end portions 37f in the width direction of the third covering body 37 may be formed in a state of being provided with side wall portions formed so as to hang vertically. In this case, the third covering body 37 will be formed in a downward U-shape (a state where the open portion of the U-shape faces downward) in a vertical cross-sectional view.

[0169] Furthermore, a plurality of slits 37g penetrating the third covering body 37 in the thickness direction are formed in the third covering body 37. The plurality of slits 37g communicate the space above and the space below the third covering body 37. Therefore, air and line of sight will pass through the plurality of slits 37g in the vertical direction.

[0170] The portion (base end portion) of the third covering body 37 on the side of the first wall portion 4a is provided integrally with the first wall portion 4a. Also, the third covering body 37 is configured to be as lightweight as possible by adopting, for example, a honeycomb structure or a flash structure so as to ensure a long protruding dimension from the first wall portion 4a.

[0171] By forming and providing the third covering body 37 as described above, a trapped space can be secured in the room space 1.

[0172] The first wall portion 4a to which the third covering 37 is attached incorporates and supports a radiant air conditioner 12. The third covering 37 also functions as air diffusion means for diffusing the indoor air whose temperature has been adjusted by the radiant heat from the radiant air conditioner 12 from the radiant air conditioner 12 to a farther place.

[0173] In the air conditioning system of the room space 1 of this embodiment, the objects located nearby can be heated or cooled by the direct radiant heat from the radiant air conditioner 12. Also, the air near the radiant air conditioner 12 will be temperature-adjusted by the radiant heat from the radiant air conditioner 12. The cooled air has the property of descending. The air (cold air) temperature-adjusted at a position above the third covering 37 flows directly below the third covering 37 through a plurality of slits 37g. Also, the cold air that did not enter the plurality of slits 37g is blocked by the third covering 37 and flows along the upper surface of the third covering 37 toward the toe side. On the other hand, the heated air has the property of rising. The air temperature-adjusted at a position below the third covering 37 temporarily stays on the curved lower surface of the third covering 37, but flows directly above the third covering 37 through a plurality of slits 37g. Thereby, the heat in the enclosed space can escape, so it is possible to suppress the heat from accumulating in the enclosed space.

[0174] The air conditioning system of the room space 1 of this embodiment as described above can contribute not only to the air conditioning of the entire room space 1 but also to the formation of a good sleeping environment in the bed 10 with one end portion 10a placed close to the first wall portion 4a side. In particular, since the both side end portions 37f in the width direction of the third covering 37 are positioned below the apex 37a which is the highest part on the lower surface of the third covering 37, for the user P with the head placed below it, the space can be widened upward. Therefore, an enclosed space that can appropriately cover the user P's head can be formed. Furthermore, in this embodiment, since a plurality of slits 37g are formed, it becomes even more difficult to feel a sense of compression. Further, in the present embodiment, the lower surface of the third covering 37 is curved upward in a vertical cross-sectional view and gradually curves downward and slopes from the apex 37a toward both end portions 37f in the width direction. Therefore, for example, compared with the case where the ceiling surface between both end portions in the width direction of the third covering 37 is flat without being curved, it becomes less likely to feel a sense of compression.

[0175] Note that the third covering 37 in the present embodiment is configured not to move up and down or adjust the angle, but it is not limited to this. It may be provided so as to be movable in the vertical direction along the wall surface of the first wall portion 4a, or may be provided so as to be angle-adjustable with respect to the wall surface of the first wall portion 4a. Alternatively, the third covering 37 may be configured to be rotatable upward and angle-adjustable in a state along the wall surface of the first wall portion 4a (in short, a folded state).

[0176] Further, the plurality of slits 37g may be formed, for example, such that the slit width becomes wider as it moves away from the wall surface of the first wall portion 4a. Also, the number of slits may increase as it moves away from the wall surface of the first wall portion 4a. Furthermore, a plurality of through holes other than the slits 37g may be formed as it moves away from the wall surface of the first wall portion 4a. Thereby, since the area of the opening formed in the third covering 37 becomes wider as it moves away from the wall surface of the first wall portion 4a, the cold air temperature-adjusted at a position above the third covering 37 can be evenly sent to the front side of the feet of the user P.

[0177] According to the present embodiment, the following excellent effects are obtained. That is, since the radiant heating and cooling device 12 is incorporated and supported in the wall portion 4 to which the covering bodies 32, 34, 37 (the first covering body 32, the second covering body 34, the third covering body 37) are attached, not only can the objects located in the vicinity be heated or cooled by the direct radiant heat from the radiant heating and cooling device 12, but also the air (cool air) whose temperature is adjusted by the radiant heating and cooling device 12 at a position above the covering bodies 32, 34, 37 can be made to descend from the protruding direction side end portion along the upper surface of the covering bodies 32, 34, 37, or the air (warm air) whose temperature is adjusted by the radiant heating and cooling device 12 at a position below the covering bodies 32, 34, 37 can be made to stay on the curved lower surface of the covering bodies 32, 34, 37 so as not to let the air escape. Thereby, a comfortable thermal environment can be formed in the room space 1 by utilizing the air whose temperature is adjusted by the radiant heating and cooling device 12. Furthermore, since the lower surfaces of the covering bodies 32, 34, 37 that protrude forward from the wall surface of the wall portion 4 are formed to curve upward in a side sectional view, for the user P who utilizes the space below the covering bodies 32, 34, 37, an effect as if the space below is widened upward is produced. Thereby, compared with the case where the lower surface of the covering bodies 32, 34, 37 is a flat ceiling surface without curvature, it becomes less likely to feel a sense of compression, so that an appropriate enclosed space with a reduced sense of compression can be secured.

[0178] Also, since the lower surfaces of the covering bodies 32, 34, 37 (the first covering body 32, the second covering body 34, the third covering body 37) are formed in a state having a first curved region 32b, 34b, 37b that gradually curves upward from the lower end portions 32d, 34d, 37d at the base end portions of the covering bodies 32, 34, 37 toward the highest apexes 32a, 34a, 37a of the lower surfaces, and a second curved region 32c, 34c that gradually curves downward from the apexes 32a, 34a, 37a toward the lower end portions 32e, 34e at the tip end portions of the covering bodies 32, 34, 37, the lower surfaces of the covering bodies 32, 34, 37 can be formed to curve upward in a side sectional view.

[0179] In addition, since both side end portions 37f in the width direction of the covering body 37 (third covering body 37) are formed in a state of being located below the apex 37a, for the user P who utilizes the lower space of the covering body 37, the sides of the lower space are covered by both side end portions 37f in the width direction of the covering body 37. As a result, the lower surface of the covering body 37 is in a state as if it is formed in a dome shape, so that an appropriate enclosed space with a reduced sense of compression can be secured.

[0180] In addition, a plurality of slits 37g penetrating the covering body 37 (third covering body 37) in the thickness direction are formed in the covering body 37, and the plurality of slits 37g communicate the upper space and the lower space of the covering body 37. Therefore, air and line of sight can pass through the plurality of slits 37g in the vertical direction, and an appropriate enclosed space where it is even more difficult to feel a sense of compression can be secured. Furthermore, the air (cool air) whose temperature is adjusted by the radiant heating and cooling device 12 at a position above the covering body 37 can be circulated directly below the covering body 37 through the plurality of slits 37g, or the air that did not enter the plurality of slits 37g can be made to descend from the protruding direction side end portion along the upper surfaces of the covering bodies 32, 34, 37. Moreover, the air (warm air) whose temperature is adjusted by the radiant heating and cooling device 12 at a position below the covering bodies 32, 34, 37 can be circulated directly above the third covering body 37 through the plurality of slits 37g while being temporarily retained on the lower surface of the covering body 37. Thereby, while warming the lower space of the covering body 37, the heat in the lower space of the covering body 37 can be gradually released, so that it is possible to suppress the heat from accumulating in the enclosed space.

[0181] In addition, an illumination device 36 that emits light upward is provided at the upper end portion of a wall body 35 (wall body 35 with illumination) that is in contact with the wall surface of the wall portion 4 and is located below the lower surface of the covering body 34 (second covering body 34). Therefore, the illumination device 36 can illuminate the lower space of the covering body 34 as indirect illumination. The light emitted from the illumination device 36 becomes soft light when it hits the lower surface of the covering body 34. Therefore, the lower space of the covering body 34 has a reduced sense of compression and becomes a calm space, and the comfort as an enclosed space can be improved.

[0182] Further, an acoustic device that emits sound upward is provided at the upper end of a wall body 35 (illuminated wall body 35) that is in contact with the wall surface of the wall portion 4 and is located below the lower surface of the covering body 34 (second covering body 34). Therefore, the sound emitted upward from the acoustic device reverberates in the space below the covering body 34, making it difficult for the sound to leak from the space below the covering body 34. On the other hand, since it is difficult for external sound to reach the user P who uses the space below the covering body 34, the comfort as an enclosed space can be improved in terms of acoustics as well.

[0183] <Third Embodiment> Next, the third embodiment will be described with reference to the drawings. For the sake of convenience of explanation, elements common to the above-described first and second embodiments are denoted by common reference numerals, and the description thereof is omitted or simplified.

[0184] The room space 1 in the present embodiment is the internal space of a room where bedding 10 is installed, such as a master bedroom (bedroom), a children's room, or a living room in a house. The room space 1 is formed by being surrounded by a floor portion 2, a ceiling portion 3, and a plurality of wall portions 4. The room space 1 is provided with bedding 10 and a radiant heating and cooling device 12. And an air conditioning system including the radiant heating and cooling device 12 is provided in the room space 1 configured as described above.

[0185] 〔Example〕 Hereinafter, the air conditioning system of the room space 1 in the present embodiment will be described in more detail. In each of the examples of the air conditioning system described below, it is assumed that the room space 1 has the configuration as described above. Also, for common elements, common reference numerals are given, and the description is omitted or simplified as appropriate.

[0186] 〔Example 3-1〕 In the room space 1 of this embodiment, as shown in FIG. 17, there is provided first air diffusion means 38 that is disposed on the side of the first wall portion 4a serving as a support and diffuses indoor air whose temperature is adjusted by radiant heat from the radiant air conditioner 12. The first air diffusion means 38 has a passage portion 38a through which line of sight and air can pass along the vertical direction.

[0187] More specifically, the first air diffusion means 38 in this embodiment is a counter 38 provided to protrude from the wall surface of the first wall portion 4a. The counter 38 is provided at a height position above the upper surface of the bed 10. Also, the bed 10 is installed such that one end portion 10a is disposed below the counter 38. That is, the counter 38 is disposed above the head of the user P.

[0188] The counter 38 is composed of a plurality of divided plate bodies 38b spaced apart in the width direction on the wall surface of the first wall portion 4a. In this embodiment, three divided plate bodies 38b are spaced apart in the width direction on the wall surface of the first wall portion 4a, and the gap 38a between these three divided plate bodies 38b serves as a passage portion 38a through which line of sight and air can pass along the vertical direction. The divided plate body 38b is formed of a rectangular plate material, and the dimension from the outer surface to the outer surface of the divided plate bodies 38b on both sides is set to be substantially equal to the width dimension of the bed 10. Also, the central divided plate body 38b is located above the central portion in the width direction of the bed 10.

[0189] The radiant air conditioner 12 is incorporated and supported on the first wall portion 4a to which the counter 38 as described above is attached.

[0190] In the air conditioning system of the room space 1 of this embodiment, it is possible to warm or cool those located in the vicinity by the direct radiant heat from the radiant air conditioner 12. In addition, the air near the radiant heating and cooling device 12 will be temperature-adjusted by the radiant heat from the radiant heating and cooling device 12. The cooled air has the property of descending. The air (cool air) temperature-adjusted at a position above the counter 38 flows directly below the partition plate body 38b (i.e., the counter 38) through a plurality of passage portions 38a between the plurality of partition plate bodies 38b. Also, the cool air that did not enter the plurality of passage portions 38a is blocked by the plurality of partition plate bodies 38b and flows along the upper surface of the plurality of partition plate bodies 38b toward the foot side. On the other hand, the warmed air has the property of ascending. The air (warm air) temperature-adjusted at a position below the counter 38 flows directly above the partition plate body 38b (i.e., the counter 38) through a plurality of passage portions 38a between the plurality of partition plate bodies 38b. Also, the warm air that did not enter the plurality of passage portions 38a is blocked by the plurality of partition plate bodies 38b and temporarily stays on the lower surface of the plurality of partition plate bodies 38b, but then flows directly above the plurality of partition plate bodies 38b through the plurality of passage portions 38a. Thereby, the heat in the space directly below the counter 38 can be released, and the accumulation of heat in the space can be suppressed.

[0191] The air conditioning system of the room space 1 of the present embodiment as described above can contribute not only to the air conditioning of the entire room space 1 but also to the formation of a good sleeping environment in the bed 10 with one end portion 10a placed closer to the first wall portion 4a. In particular, the counter 38 is composed of a plurality of partition plate bodies 38b arranged at intervals from each other, and the gaps between the plurality of partition plate bodies 38b serve as passage portions 38a through which the line of sight and air can pass along the vertical direction. Therefore, the user P with their head placed below it is less likely to feel a sense of oppression compared to the case where the line of sight and air cannot pass through. In addition to this, the plurality of partition plate bodies 38b can effectively diffuse the cool air temperature-adjusted at a position above the counter 38 and the warm air temperature-adjusted at a position below the counter 38.

[0192] Note that although the counter 38 in this embodiment is configured not to move up and down or adjust its angle, it is not limited to this. It may be provided so as to be movable in the vertical direction along the wall surface of the first wall portion 4a, or may be provided so as to be angle-adjustable with respect to the wall surface of the first wall portion 4a. Alternatively, the counter 38 may be configured to be rotatable upward and angle-adjustable in a state along the wall surface of the first wall portion 4a (that is, in a folded state). When configured to enable vertical movement and angle adjustment, the plurality of divided plate bodies 38b may be separately vertically movable and angle-adjustable, or may be vertically movable and angle-adjustable all at once.

[0193] Note that the counter 38 in this embodiment is composed of a plurality of divided plate bodies 38b, and the gap between these plurality of divided plate bodies 38b is defined as a passage portion 38a through which the line of sight and air can pass along the vertical direction. However, it is not limited to this. That is, as shown in FIG. 18, a passage portion may be formed by processing a single counter 39, 40, 41 provided to protrude from the wall surface of the first wall portion 4a.

[0194] The counter 39 shown in FIG. 18(a) forms a notch portion 39a in an arc shape, and the notch portion 39a is defined as a passage portion 39a through which the line of sight and air can pass along the vertical direction. The notch portion 39a, which is the passage portion 39a, is formed in a semi-circular shape at the center in the width direction of the counter 39, and the head of the user P located directly below is not completely covered by the counter 39.

[0195] The counter 40 shown in FIG. 18(b) has a plurality of slits 40a formed to be long along the length direction of the counter 40 and penetrating through the plate material of the counter 40 in the thickness direction, and these slits 40a are defined as passage portions 40a through which the line of sight and air can pass along the vertical direction. The plurality of slits 40a, which are the through portions 40a, are arranged at intervals in the protruding direction from the wall surface of the first wall portion 4a of the counter 40, and the head of the user P located directly below is not completely covered by the counter 40.

[0196] The counter 41 shown in FIG. 18(c) has a plurality of through holes 41a formed by penetrating the plate material of the counter 41 in the thickness direction, and serves as through portions 41a through which line of sight and air can pass along the vertical direction. The plurality of through holes 41a, which are the through portions 41a, are arranged in a staggered pattern, and the head of the user P located directly below is not completely covered by the counter 41.

[0197] The air (cool air) whose temperature has been adjusted above these counters 39, 40, 41 flows directly below the counters 39, 40, 41 through the through portions 39a, 40a, 41a. Also, the cool air that did not enter the through portions 39a, 40a, 41a is blocked by the counters 39, 40, 41 and flows along the upper surfaces of the counters 39, 40, 41 toward the foot side. On the other hand, the air (warm air) whose temperature has been adjusted below the counters 39, 40, 41 flows directly above the counters 39, 40, 41 through the through portions 39a, 40a, 41a. Also, the warm air that did not enter the through portions 39a, 40a, 41a is blocked by the counters 39, 40, 41 and temporarily stays on the lower surfaces of the counters 39, 40, 41, but then flows directly above the counters 39, 40, 41 through the through portions 39a, 40a, 41a. Thereby, the heat in the space directly below the counters 39, 40, 41 can be released, and the accumulation of heat in the space can be suppressed.

[0198] 〔Example 3-2〕 In the room space 1 of this example, as shown in FIG. 19, a second air diffusion means 42 is provided on the side of the first wall portion 4a, which is a support, and diffuses the indoor air whose temperature has been adjusted by the radiant heat from the radiant heating and cooling device 12. And the second air diffusion means 42 has a through portion 42a through which line of sight and air can pass along the vertical direction.

[0199] More specifically, the second air diffusion means 42 in this embodiment is a counter 42 provided so as to protrude from the wall surface of the first wall portion 4a. The counter 42 is provided at a height position above the upper surface of the bed 10. Further, the bed 10 is installed such that one end portion 10a is disposed below the counter 42. That is, the counter 42 is disposed above the head of the user P.

[0200] The counter 42 includes a bulging portion 43 formed to bulge downward at the central portion in the width direction of the rectangular plate material constituting the counter 42, and a notch portion 43a is formed in the lowermost portion of the bulging portion 43. The bulging portion 43 is formed to gently slope downward from the upper surface of the plate material of the counter 42. The bulging portion 43 is formed in a U shape in plan view. The bottom plate portion of the bulging portion 43 is notched in a U shape in plan view, thereby forming the notch portion 43a. And this notch portion 43a serves as a passage portion 43a through which the line of sight and air can pass along the vertical direction.

[0201] Further, the counter 42 includes side wall portions 44 integrally formed at both ends in the width direction and fixed to the wall surface of the first wall portion 4a. Such side wall portions 44 extend downward from both ends in the width direction of the counter 42 and are formed such that the vertical dimension gradually increases as they go toward the wall surface side of the first wall portion 4a. That is, these side wall portions 44 function as brackets for supporting the counter 42.

[0202] The radiant heating / cooling device 12 is incorporated and supported in the first wall portion 4a to which the counter 42 as described above is attached.

[0203] In the air conditioning system of the room space 1 of this embodiment, the objects located in the vicinity can be heated or cooled by the direct radiant heat from the radiant heating / cooling device 12. In addition, the air near the radiative air conditioner 12 will be temperature-adjusted by the radiative heat from the radiative air conditioner 12. The cooled air has the property of descending. The air (cool air) temperature-adjusted at a position above the counter 42 flows directly below the counter 42 through the passage portion 43a formed by a notch at the lower end of the bulging portion 43. The upper surface of the bulging portion 43 is formed in a gently inclined state. Therefore, the air gathering at the central portion in the width direction of the counter 42 easily flows into the lower space along the upper surface of the bulging portion 43. Also, the cool air that did not enter the passage portion 43a is blocked by the counter 42 and flows along the upper surface of the counter 42 toward the toe side. On the other hand, the warmed air has the property of ascending. The air (warm air) temperature-adjusted at a position below the counter 42 flows directly above the counter 42 through the passage portion 43a formed by a notch at the lower end of the bulging portion 43. Also, the warm air that did not enter the passage portion 43a is blocked by the counter 42 and the side wall portions 44 on both sides, and is likely to stay on the lower surface of the double counter 42. Thus, for those who want to prevent the warm air from escaping all at once from the passage portion 43a, the counter 42 can effectively suppress the escape of the ascending warm air as much as possible.

[0204] The air conditioning system of the room space 1 of the present embodiment as described above can contribute not only to the air conditioning of the entire room space 1 but also to the formation of a good sleeping environment in the bed 10 with one end portion 10a placed close to the first wall portion 4a. In particular, since the notch portion 43a formed at the lower end of the bulging portion 43 of the counter 42 is the passage portion 43a through which the line of sight and air can pass along the vertical direction, the user P with the head placed below it is less likely to feel a sense of compression compared to the case where the line of sight and air cannot pass through. In addition to this, the plate material constituting the counter 42 and the bulging portion 43 can effectively diffuse the cool air temperature-adjusted at a position above the counter 42 and the warm air temperature-adjusted at a position below the counter 42.

[0205] Note that, although the counter 42 in this embodiment is configured not to move up and down or adjust its angle, it is not limited to this. It may be provided so as to be movable in the vertical direction along the wall surface of the first wall portion 4a, or may be provided so as to be angle-adjustable with respect to the wall surface of the first wall portion 4a. Alternatively, the counter 42 may be configured to be angle-adjustable by rotating it upward to a state along the wall surface of the first wall portion 4a (i.e., a folded state).

[0206] 〔Embodiment 3-3〕 As shown in FIG. 20, in the room space 1 of this embodiment, third air diffusion means 45 is provided on the side of the first wall portion 4a which is a support, and diffuses the indoor air whose temperature is adjusted by the radiant heat from the radiant heating and cooling device 12. The third air diffusion means 45 has a passage portion 45a through which the line of sight and air can pass along the vertical direction.

[0207] More specifically, the third air diffusion means 45 in this embodiment is a counter 45 provided so as to protrude from the wall surface of the first wall portion 4a. The counter 45 is provided at a height position above the upper surface of the bed 10. Also, the bed 10 is installed such that one end portion 10a is disposed below the counter 45. That is, the counter 45 is disposed above the head of the user P.

[0208] As shown in FIGS. 20(a) and 20(b), the counter 45 is composed of a plurality of divided plate bodies 45b arranged at intervals in the width direction on the wall surface of the first wall portion 4a. In this embodiment, two divided plate bodies 45b are arranged at intervals in the width direction on the wall surface of the first wall portion 4a, and the gap 45a between these two divided plate bodies 45b serves as a passage portion 45a through which the line of sight and air can pass along the vertical direction. The divided plate body 45b is formed of a rectangular plate material, and the dimension from the outer surface of one divided plate body 45b to the outer surface of the other divided plate body 45b is set to be substantially equal to the width dimension of the bed 10.

[0209] In the example shown in Fig. 20(a), the passage portion 45a, which is the gap between the two divided plate bodies 45b, can be opened and closed by the two opening / closing bodies 46. Each opening / closing body 46 is attached to the lower surface of the respective divided plate body 45b via a movable mechanism 46a such as a slide rail. Also, these opening / closing bodies 46 are located below the lower surface of the respective divided plate body 45b. Note that the dimension between the two divided plate bodies 45b is set shorter than the dimension when the two opening / closing bodies 46 are arranged side by side horizontally, and the two opening / closing bodies 46 can surely close the passage portion 45a, which is the gap between the two divided plate bodies 45b.

[0210] Also in the example shown in Fig. 20(b), the passage portion 45a, which is the gap between the two divided plate bodies 45b, can be opened and closed by the two opening / closing bodies 46. Each opening / closing body 46 is attached to the top surface within the recess 45c formed on the lower surface of the respective divided plate body 45b via a movable mechanism 46a such as a slide rail. Also, these opening / closing bodies 46 are located above the lower surface of the respective divided plate body 45b. Note that the dimension between the two divided plate bodies 45b is set shorter than the dimension when the two opening / closing bodies 46 are arranged side by side horizontally, and the two opening / closing bodies 46 can surely close the passage portion 45a, which is the gap between the two divided plate bodies 45b.

[0211] The opening / closing body 46 in this embodiment is configured to open and close the passage portion 45a by performing an operation of opening and closing in the width direction of the counter 45 by a movable mechanism 46a such as a long slide rail along the length direction of the counter 45, but it is not limited to this. That is, the opening / closing operation of the opening / closing body 46 is not limited to that by the long slide rail 46a. The opening / closing body 46 and the divided plate body 45b may be rotatably connected via a hinge (i.e., a movable mechanism), and the opening / closing body 46 may be rotated in the vertical direction to open and close the passage portion 45a. Alternatively, one corner of the opening / closing body 46 and one corner of the partition plate body 45b may be connected via a rotating shaft (i.e., a movable mechanism) so as to be horizontally rotatable, and the opening / closing body 46 may be rotated horizontally to open and close the passage portion 45a. Furthermore, although the opening / closing body 46 in the present embodiment is in a state of being located below the partition plate body 45b, it is not limited thereto, and it may be in a state of being located above the partition plate body 45b. That is, it may be in a state where the top and bottom are reversed from the states shown in FIGS. 20(a) and (b).

[0212] The radiant heating / cooling device 12 is incorporated and supported in the first wall portion 4a to which the counter 45 as described above is attached.

[0213] In the air conditioning system of the room space 1 of the present embodiment, the objects located in the vicinity can be heated or cooled by the direct radiant heat from the radiant heating / cooling device 12. Also, the air near the radiant heating / cooling device 12 will be temperature-adjusted by the radiant heat from the radiant heating / cooling device 12. Among the air temperature-adjusted by the radiant heating / cooling device 12, the air temperature-adjusted at a position above the counter 45 which is the third air diffusion means will hardly flow directly below the counter 45 when the passage portion 45a is blocked by the opening / closing body 46. Furthermore, the air temperature-adjusted at a position below the counter 45 which is the third air diffusion means will hardly flow directly above the counter 45 when the passage portion 45a is blocked by the opening / closing body 46.

[0214] More specifically, the cooled air has the property of descending. The air (cool air) temperature-adjusted at a position above the counter 45 will hardly flow directly below the counter 45 when the passage portion 45a is blocked by the opening / closing body 46. Therefore, for a person who dislikes cold air hitting the face, by blocking the passage portion 45a with the opening / closing body 46, the descending cold air can be blocked as much as possible. The cold air blocked by the counter 45 will descend from the protruding-direction side end of the counter 45 (and the end on the toe side of the user P), so it will be easier to flow to the toe side than the head of the user P. For a person who doesn't mind the cold air hitting their face, open the opening / closing body 46 to open the passage part 45a, and let the descending cold air flow below the counter 45.

[0215] On the other hand, the warmed air has the property of rising. The air whose temperature is adjusted at a position below the counter 45 is less likely to flow directly above the counter 45. Therefore, for a person who wants to prevent the warm air from escaping, by closing the passage part 45a with the opening / closing body 46, it is possible to extremely suppress the escape of the rising warm air. For a person who wants to prevent the warm air from being trapped, open the opening / closing body 46 to open the passage part 45a, and let the rising warm air flow above the counter 45.

[0216] That is, the counter 45, which is the third air diffusion means, can control the air flow in a plurality of patterns by appropriately opening and closing the opening / closing body 46, so it also functions as an air flow control means. Therefore, the air conditioning system of the room space 1 in the present embodiment as described above can contribute not only to the air conditioning of the entire room space 1 but also to the formation of a good sleeping environment in the bed 10 with one end 10a placed close to the first wall part 4a.

[0217] Furthermore, since the opening / closing body 46 of the counter 45 is configured to be openable and closable, if the opening / closing body 46 is opened to open the passage part 45a, the first wall part 4a (or the fukashi wall 5) can be used as the headboard of the bed 10 and the user P can use it as a backrest.

[0218] 〔Embodiment 3 - 4〕 In the room space 1 of this embodiment, as shown in FIG. 21, fourth air diffusion means 47 is provided on the side of the first wall portion 4a which is a support, and diffuses indoor air whose temperature is adjusted by radiant heat from the radiant heating and cooling device 12. The fourth air diffusion means 47 has a passage portion 47a through which line of sight and air can pass along the vertical direction.

[0219] More specifically, the fourth air diffusion means 47 in this embodiment is a counter 47 provided so as to protrude from the wall surface of the first wall portion 4a. The counter 47 is provided at a height position above the upper surface of the bed 10. Also, the bed 10 is installed such that one end portion 10a is disposed below the counter 47. That is, the counter 47 is disposed above the head of the user P.

[0220] As shown in FIG. 21, the counter 47 includes a rectangular opening 47a formed by penetrating the plate material forming the counter 47 in the thickness direction at the center of the rectangular plate material constituting the counter 47, and this opening 47a serves as the passage portion 47a through which line of sight and air can pass along the vertical direction. Also, the width dimension of the counter 47 is set to be substantially equal to the width dimension of the bed 10.

[0221] A louver device 48 is provided in the passage portion 47a which is an opening formed in the center of the counter 47 as an opening / closing body for opening and closing the passage portion 47a. The louver device 48 has a frame body fixed to the peripheral edge of the passage portion 47a which is an opening, and a plurality of fins 48a formed in a long shape along the width direction of the counter 47 and held by the frame body. The plurality of fins 48a have a rotation axis passing therethrough along the longitudinal direction, and are attached to the frame body so as to be rotatable about the axis of the rotation axis. In the example shown in FIG. 21, if the plurality of fins 48a are rotated to a state where they are laid in the same direction and the fins 48a are brought into contact with each other, the passage portion 47a, which is an opening, can be blocked. Further, if the plurality of fins 48a are rotated in the same direction and the fins 48a are separated from each other, the passage portion 47a, which is an opening, can be opened.

[0222] The radiation heating and cooling device 12 is incorporated and supported in the first wall portion 4a to which the counter 47 as described above is attached.

[0223] In the air conditioning system of the room space 1 of the present embodiment, the objects located in the vicinity can be heated or cooled by the direct radiant heat from the radiation heating and cooling device 12. In addition, the air near the radiation heating and cooling device 12 is temperature-adjusted by the radiant heat from the radiation heating and cooling device 12. Among the air temperature-adjusted by the radiation heating and cooling device 12, the air temperature-adjusted at a position above the counter 47, which is the fourth air diffusion means, is less likely to flow directly below the counter 47 when the passage portion 47a is blocked by the plurality of fins 48a. Further, the air temperature-adjusted at a position below the counter 47, which is the fourth air diffusion means, is less likely to flow directly above the counter 47 when the passage portion 47a is blocked by the plurality of fins 48a.

[0224] More specifically, the cooled air has the property of descending. The air (cold air) temperature-adjusted at a position above the counter 47 is less likely to flow directly below the counter 47 when the passage portion 47a is blocked by the plurality of fins 48a. Therefore, for a person who dislikes cold air hitting the face, by blocking the passage portion 47a with the plurality of fins 48a, the descending cold air can be blocked as much as possible. The cold air blocked by the counter 47 will descend from the protruding direction side end of the counter 47 (and the end on the toe side of the user P), so it will be easier to flow to the toe side than the head of the user P. In the case of a person who doesn't mind the cold air hitting their face, rotate the plurality of fins 48a to open the passage portion 47a, and let the descending cold air flow below the counter 47.

[0225] On the other hand, the warmed air has the property of rising. The air whose temperature is adjusted at a position below the counter 47 is less likely to flow directly above the counter 47. So, for a person who wants to prevent the warm air from escaping, by closing the passage portion 47a with the plurality of fins 48a, it is possible to extremely suppress the escape of the rising warm air. In the case of a person who wants to prevent the warm air from accumulating, rotate the plurality of fins 48a to open the passage portion 47a, and let the rising warm air flow above the counter 47.

[0226] That is, the counter 47, which is the third air diffusion means, can control the air flow in a plurality of patterns by appropriately opening and closing the plurality of fins 48a of the opening and closing body 48, so it also functions as an air flow control means. Therefore, the air conditioning system of the room space 1 in the present embodiment as described above can contribute not only to the air conditioning of the entire room space 1 but also to the formation of a good sleeping environment in the bed 10 with one end portion 10a placed close to the first wall portion 4a. Note that the angle adjustment of the plurality of fins 48a is performed automatically or manually. When it is performed automatically, the louver device 48, which is an opening and closing body, includes a drive unit for rotating the plurality of fins 48a. This drive unit can be controlled with the same configuration as the above automatic control system (see Fig. 6). That is, the drive unit is connected to a control device constituted by a computer by wire or wirelessly, and is controlled by the control device according to a program stored in the storage unit. Also, the control device is configured to control the drive unit according to the sensing result of the state detection sensor 21 provided in the room space 1.

[0227] According to this embodiment, the following excellent effects can be achieved. That is, the counters 38, 39, 40, 41, 42, 45, 47 protruding forward from the wall surface of the wall portion 4 have passing portions 38a, 39a, 40a, 41a, 43a, 45a, 47a that allow at least the line of sight and air to pass through along the vertical direction of the counters 38, 39, 40, 41, 42, 45, 47. Therefore, the line of sight can pass through vertically through the passing portions 38a, 39a, 40a, 41a, 43a, 45a, 47a, and air can also pass through vertically. As a result, it becomes difficult for the user P to feel a sense of oppression, so a sleep environment with the sense of oppression suppressed as much as possible can be formed. Furthermore, since the radiant heating and cooling device 12 is incorporated and supported in the wall portion 4 to which the counters 38, 39, 40, 41, 42, 45, 47 are attached, in addition to being able to warm or cool the objects located in the vicinity by the direct radiant heat from the radiant heating and cooling device 12, the air (cold air) whose temperature is adjusted by the radiant heating and cooling device 12 above the counters 38, 39, 40, 41, 42, 45, 47 can be made to descend into the lower space through the passing portions 38a, 39a, 40a, 41a, 43a, 45a, 47a, or can be made to descend from the protruding direction side end portion along the upper surface of the counters 38, 39, 40, 41, 42, 45, 47. Also, the air (warm air) whose temperature is adjusted by the radiant heating and cooling device 12 below the counters 38, 39, 40, 41, 42, 45, 47 can be released upward from the passing portions 38a, 39a, 40a, 41a, 43a, 45a, 47a to suppress heat accumulation. Thereby, a comfortable temperature environment can be formed in the room space 1 by using the air whose temperature is adjusted by the radiant heating and cooling device 12.

[0228] Further, since the gaps between the plurality of divided plate bodies 38b and 45b arranged at intervals in the width direction on the wall surface of the wall portion 4 are the passage portions 38a and 45a, the line of sight can pass through the passage portions 38a and 45a in the vertical direction, and air can also pass through in the vertical direction. As a result, it becomes difficult for the user P to feel a sense of compression, so that a sleep environment with the sense of compression suppressed as much as possible can be formed. Furthermore, since the radiant heating / cooling device 12 is incorporated and supported in the wall portion 4 to which the counters 38 and 45 are attached, in addition to being able to warm or cool the objects located in the vicinity by the direct radiant heat from the radiant heating / cooling device 12, the cooled air whose temperature is adjusted at a position above the counters 38 and 45 and the warmed air whose temperature is adjusted at a position below the counters 38 and 45 can be effectively diffused. Thereby, a comfortable temperature environment can be formed in the room space 1 by using the air whose temperature is adjusted by the radiant heating / cooling device 12.

[0229] Moreover, since the counter 45 further includes an opening / closing body 46 that opens and closes the passage portion 45a, the line of sight can be prevented from passing through by closing the passage portion 45a with the opening / closing body 46. Furthermore, by appropriately opening and closing the passage portion 45a with the opening / closing body 46, it is possible to control the flow of the cooled air whose temperature is adjusted at a position above the counter 45 and the flow of the warmed air whose temperature is adjusted at a position below the counter 45 in a plurality of patterns.

[0230] In addition, since the passage portions 39a and 43a are notch portions 39a and 43a formed by notches at the edges of the counters 39 and 42, the user P who uses the space below the counters 39 and 42 is less likely to feel a sense of compression than when the line of sight and the passage of air are blocked. Furthermore, in forming a comfortable temperature environment in the room space 1 by using the cooled air whose temperature is adjusted at a position above the counters 39 and 42 and the warmed air whose temperature is adjusted at a position below the counters 39 and 42, for example, when the opening formed in the counter is used as the passage portion or when the gap between the plates spaced apart from each other is used as the passage portion, an air flow different from that in these cases can be formed.

[0231] Further, since the notch 43a is formed in the lowermost part of the bulging part 43 formed in the central part in the width direction of the plate material constituting the counter 42, the air (cool air) gathering in the central part in the width direction of the counter 42 can easily flow to the lower space along the upper surface of the bulging part 43, and can be easily lowered from the notch 43a.

[0232] Also, since the passing parts 40a, 41a, 47a are openings 40a, 41a, 47a penetrating the counters 40, 41, 47 in the thickness direction, a user P using the lower space of the counters 40, 41, 47 is less likely to feel a sense of oppression than when the line of sight and the passage of air are not possible. Furthermore, in forming a comfortable thermal environment in the room space 1 by using the cool air whose temperature is adjusted at a position above the counters 40, 41, 47 and the warm air whose temperature is adjusted at a position below the counters 40, 41, 47, for example, when a notch formed at the edge of the counter is used as the passing part, or when the gap between the plate bodies separated from each other is used as the passing part, an air flow different from these cases can be formed.

[0233] Also, the opening / closing body 48 for opening and closing the passing part 47a is a louver device 48 provided in the passing part 47a and having a plurality of fins 48a arranged in parallel and rotatable around the axis of the rotation axis. Therefore, by closing the passing part 45a with the plurality of fins 48a, it is possible to prevent the line of sight from passing through. Furthermore, by appropriately opening and closing the passing part 45a with the plurality of fins 48a, it is possible to control the flow of the cool air whose temperature is adjusted at a position above the counter 47 and the flow of the warm air whose temperature is adjusted at a position below the counter 47 in a plurality of patterns.

[0234] <Fourth Embodiment> Next, the fourth embodiment will be described with reference to the drawings. For the sake of convenience of explanation, elements common to the first to third embodiments described above are denoted by common reference numerals, and the description thereof is omitted or simplified.

[0235] The room space 1 in this embodiment is the internal space of a room where bedding 10 is installed, such as the master bedroom (bedroom), children's room, living room, etc. within a house. The room space 1 is formed by being surrounded by a floor portion 2, a ceiling portion 3, and a plurality of wall portions 4. The room space 1 is equipped with bedding 10 and a radiant heating and cooling device 12. And in the room space 1 configured as described above, an air conditioning system including the radiant heating and cooling device 12 is provided.

[0236] 〔Example〕 Hereinafter, the air conditioning system of the room space 1 in this embodiment will be described in more detail. Note that in each example of the air conditioning system described below, it is assumed that the room space 1 has the configuration as described above. Also, for common elements, common reference numerals are given, and the description will be omitted or simplified as appropriate.

[0237] 〔Example 4 - 1〕 In the room space 1 of this example, as shown in FIGS. 22(a) and (b), a counter 49, which is a fifth air diffusion means, is provided on the side of the first wall portion 4a serving as a support, and diffuses indoor air whose temperature is adjusted by radiant heat from the radiant heating and cooling device 12. And on the lower surface of the counter 49, illuminance increasing means 50, 51 for increasing the illuminance in the space below the counter 49 are provided.

[0238] More specifically, the counter 49, which is the fifth air diffusion means of this example, is provided protruding from the wall surface of the first wall portion 4a. The counter 49 is provided at a height position above the upper surface of the bed 10. Also, the bed 10 is installed such that one end portion 10a is disposed below the counter 49. That is, the counter 49 will be disposed above the head of the user P.

[0239] The counter 49 is composed of a rectangular plate material, and the width dimension is set to be substantially equal to the width dimension of the bed 10. On the lower surface of such a counter 49, lighting devices 50 and 51 are provided as illuminance increasing means. The lighting devices 50 and 51 are, for example, LED lighting devices, and are connected to a power supply unit (not shown) to receive power supply.

[0240] Further, the lighting devices 50 and 51 are configured to be able to adjust not only the on / off state but also the illuminance by the operation of a controller (not shown). Furthermore, the controller is provided with a timer function, and the on / off state and illuminance adjustment of the lighting device 36 can be controlled by the timer. Note that the controller can be substituted with a computer such as a smartphone in which a dedicated application has been downloaded.

[0241] In the example shown in FIG. 22(a), the lighting device 50 is of the direct lighting type and is in a state of being exposed on the lower surface of the counter 49. In the example shown in FIG. 22(b), the lighting device 51 is of the indirect lighting type and is not exposed on the lower surface of the counter 49. That is, a lighting housing portion 52 formed in a substantially J shape in a side cross-sectional view is provided at the protruding direction side end portion of the counter 49, and the lighting device 51 is housed in this lighting housing portion 52 so that the light from the lighting device 51 does not directly enter the eyes of the user P below the counter 49. Note that the lighting housing portion 52 has a first plate 52a extending downward from the protruding direction side end portion of the counter 49, a second plate 52b extending from the lower end portion of the first plate 52a toward the first wall portion 4a side and having the lighting device 51 provided on the upper surface, and a third plate 52c extending upward from the first wall portion 4a side end portion in the second plate 52b. A gap is formed between the upper end portion of the third plate 52c and the lower surface of the counter 49, and the light of the lighting device 51 leaks from this gap. The second plate 52b functions as a shielding plate for preventing the light from directly reaching the user P using the lower space.

[0242] In the first wall portion 4a to which the counter 49 as described above is attached, a radiant heating / cooling device 12 is incorporated and supported.

[0243] In the air conditioning system of the room space 1 of this embodiment, the objects located in the vicinity can be heated or cooled by the direct radiant heat from the radiant heating and cooling device 12. Also, the air near the radiant heating and cooling device 12 will be temperature-adjusted by the radiant heat from the radiant heating and cooling device 12. Among the air whose temperature is adjusted by the radiant heating and cooling device 12, the air whose temperature is adjusted at a position above the counter 49, which is the fifth air diffusion means, will be less likely to flow directly below the counter 49. Furthermore, the air whose temperature is adjusted at a position below the counter 49 will be less likely to flow directly above the counter 49.

[0244] More specifically, the cooled air has the property of descending. Since the air whose temperature is adjusted at a position above the counter 49 is less likely to flow directly below the counter 49, for those who dislike cold air hitting their faces, the counter 49 can block the descending cold air as much as possible. The cold air blocked by the counter 49 will descend from the protruding direction side end (and the width direction side end) of the counter 49, so it will be easier to flow to the toe side rather than the head of the user P.

[0245] On the other hand, the warmed air has the property of ascending. Since the air whose temperature is adjusted at a position below the counter 49 is less likely to flow directly above the counter 49, for those who want to prevent warm air from escaping, the counter 49 can suppress the escape of the ascending warm air as much as possible. In particular, if a drooping lighting storage part 52 is provided at the protruding direction side end of the counter 49, the warm air whose temperature is adjusted at a position below the counter 49 will be likely to stay on the lower surface of the counter 49, so the escape of the ascending warm air can be suppressed as much as possible.

[0246] The air conditioning system of the room space 1 of this embodiment as described above can contribute not only to the air conditioning of the entire room space 1 but also to the formation of a good sleeping environment in the bed 10 with one end 10a placed close to the first wall portion 4a side. In addition, by providing the lighting devices 50 and 51 on the lower surface of the counter 49, it is possible to adjust the illuminance in the space below the counter 49. Thus, even if the space below the counter 49 becomes a space with low illuminance due to being in the shade of the counter 49, the space below the counter 49 can be brightened, which can also contribute to the formation of a good waking-up environment.

[0247] Note that the counter 49 in this embodiment is configured not to move up and down or adjust its angle, but it is not limited to this. It may be provided so as to be movable in the vertical direction along the wall surface of the first wall portion 4a, or may be provided so as to be angle-adjustable with respect to the wall surface of the first wall portion 4a. Alternatively, the counter 49 may be configured to be rotatable upward and angle-adjustable in a state along the wall surface of the first wall portion 4a (that is, in a folded state).

[0248] 〔Embodiment 4-2〕 In the room space 1 of this embodiment, as shown in FIG. 23, there is provided a counter 53 which is a sixth air diffusion means for diffusing the indoor air adjusted in temperature by the radiant heat from the radiant heating and cooling device 12 and is arranged on the side of the first wall portion 4a which is a support. And on the lower surface of the counter 53, there is provided an illuminance increasing means 54 for increasing the illuminance in the space below the counter 53.

[0249] More specifically, the counter 53 which is the sixth air diffusion means 53 of this embodiment is provided to protrude from the wall surface of the first wall portion 4a. The counter 53 is provided at a height position above the upper surface of the bed 10. Also, the bed 10 is installed such that one end 10a is arranged below the counter 53. That is, the counter 53 will be arranged above the head of the user P.

[0250] The counter 53 is composed of a rectangular plate material, and its width dimension is set to be approximately equal to the width dimension of the bed 10. On the lower surface of such a counter 53, a monitor 54 is provided as an illuminance increasing means. The monitor 54 refers to a device on which characters, figures, graphics, videos, etc. are displayed, and is also referred to as a display or a display device. In addition, a tablet terminal or a TV having a display unit with the same function may be used instead. Such a monitor 54 is connected to a power supply unit (not shown) and receives power supply. Further, the monitor 54 is configured to be able to adjust not only the on / off but also the illuminance of the screen by operating a controller (not shown). Furthermore, the monitor 54 may be equipped with a speaker and a microphone.

[0251] And the monitor 54 may not only adjust the illuminance but also eliminate the sense of oppression caused by the presence of the counter 53 above the head by an image or the like displayed on the screen. For example, by displaying a night sky on the screen of the monitor 54 at bedtime or a blue sky on the screen of the monitor 54 at wake-up time, a sense of passing through the line of sight can be given to the user P, so that the sense of oppression can be eliminated. Also, a video of a natural environment such as a forest may be projected. Furthermore, a camera may be installed on the counter 53 so as to project the ceiling portion 3, or a camera may be actually installed on the roof so that the scenery captured by the camera is projected onto the monitor 54.

[0252] A recess 53a is formed on the lower surface of the counter 53, and the monitor 54 is housed in this recess 53a. When, for example, a tablet terminal is used as the monitor 54, the monitor 54 housed in the recess 53a may be held by a fastener such as a so-called dragonfly so that it can be easily housed in and taken out of the recess 53a.

[0253] In the first wall portion 4a to which the counter 49 as described above is attached, a radiant heating and cooling device 12 is incorporated and supported.

[0254] In the air conditioning system of the room space 1 of this embodiment, the direct radiant heat from the radiant heating and cooling device 12 can warm or cool those located in the vicinity. Also, the air near the radiant heating and cooling device 12 will be temperature-adjusted by the radiant heat from the radiant heating and cooling device 12. Among the air temperature-adjusted by the radiant heating and cooling device 12, the air temperature-adjusted at a position above the counter 53, which is the sixth air diffusion means, will be less likely to flow directly below the counter 53. Furthermore, the air temperature-adjusted at a position below the counter 53 will be less likely to flow directly above the counter 53.

[0255] More specifically, the cooled air has the property of descending. Since the air temperature-adjusted at a position above the counter 53 is less likely to flow directly below the counter 53, for those who dislike cold air hitting their faces, the counter 53 can block the descending cold air as much as possible. The cold air blocked by the counter 53 will descend from the protruding direction side end (and the width direction side end) of the counter 53, so it will be easier to flow to the toe side rather than the head of the user P.

[0256] On the other hand, the warmed air has the property of rising. Since the air temperature-adjusted at a position below the counter 53 is less likely to flow directly above the counter 53, for those who want to prevent warm air from escaping, the counter 53 can suppress the escape of the rising warm air as much as possible. Note that the warm air temperature-adjusted at a position below the counter 53 gradually rises and diffuses from the protruding direction side end of the counter 53.

[0257] The air conditioning system of the room space 1 of this embodiment as described above can contribute not only to the air conditioning of the entire room space 1 but also to the formation of a good sleeping environment in the bed 10 with one end 10a placed close to the first wall portion 4a. In addition, by providing the monitor 54 on the lower surface of the counter 53, it is possible to adjust the illuminance in the space below the counter 53. As a result, even if the space below the counter 53 becomes a space with low illuminance due to being in the shade of the counter 53, the space below the counter 53 can be brightened, contributing to the formation of a good waking-up environment.

[0258] Note that the counter 53 in the present embodiment is configured not to move up and down or adjust its angle, but it is not limited to this. It may be provided so as to be movable in the vertical direction along the wall surface of the first wall portion 4a, or may be provided so as to be angle-adjustable with respect to the wall surface of the first wall portion 4a. Alternatively, the counter 53 may be configured to be angle-adjustable by rotating it upward to a state along the wall surface of the first wall portion 4a (in short, a folded state).

[0259] 〔Embodiment 4-3〕 In the room space 1 of the present embodiment, as shown in FIG. 24, a counter 55 is provided, which is the seventh air diffusion means 55 that is arranged on the side of the first wall portion 4a serving as a support and diffuses the indoor air whose temperature is adjusted by the radiant heat from the radiant heating and cooling device 12. And on the lower surface of the counter 55, an illuminance increasing means 56 for increasing the illuminance in the space below the counter 55 is provided.

[0260] More specifically, the counter 55, which is the seventh air diffusion means 55 of the present embodiment, is provided to protrude from the wall surface of the first wall portion 4a. The counter 55 is provided at a height position above the upper surface of the bed 10. Also, the bed 10 is installed such that one end portion 10a is disposed below the counter 55. That is, the counter 55 is disposed above the head of the user P.

[0261] The counter 55 is formed of a rectangular plate material, and the width dimension is set to be substantially equal to the width dimension of the bed 10. On the lower surface of such a counter 55, a mirror 56 is provided as an illuminance increasing means with its mirror surface facing downward and inclined obliquely. Therefore, when lying on the bed 10 with the head placed below the mirror 56, the light taken in from the outside of the space below the counter 55 reaches the eyes of the user P. That is, if the room space 1 is darkened at bedtime, it is difficult for light to reach the eyes of the user P, but in the morning, the natural light shining into the room space 1 from the outside becomes easier to reach the eyes of the user P. Also, the user P can see the foot side through the mirror 56 without raising the head, which can contribute to relieving the sense of oppression caused by the counter 55 above the head.

[0262] The mirror 56 is a normal mirror and is provided spanning between the lower surface portion at the protruding direction side end of the counter 55 and the first wall portion 4a. On the lower surface portion at the protruding direction side end of the counter 55, an insertion groove 55a formed to be long along the width direction of the counter 55 is formed, and the upper end portion of the mirror 56 is inserted into this insertion groove 55a. Also, on the wall surface of the first wall portion 4a, a mirror receiving portion 57 for receiving the lower end portion of the mirror 56 is attached. The mirror receiving portion 57 has an obliquely upward facing surface as the protruding direction side end face, and an insertion groove 57a is formed in the protruding direction side end face. And the upper end portion of the mirror 56 is inserted into this insertion groove 57a.

[0263] In the first wall portion 4a to which the counter 55 as described above is attached, a radiant heating and cooling device 12 is incorporated and supported.

[0264] In the air conditioning system of the room space 1 of this embodiment, the objects located in the vicinity can be heated or cooled by the direct radiant heat from the radiant heating and cooling device 12. In addition, the air near the radiant air conditioner 12 will be temperature-adjusted by the radiant heat from the radiant air conditioner 12. Among the air temperature-adjusted by the radiant air conditioner 12, the air temperature-adjusted at a position above the counter 55 which is the seventh air diffusion means will be less likely to flow directly below the counter 55. Further, the air temperature-adjusted at a position below the counter 55 will be less likely to flow directly above the counter 55.

[0265] More specifically, the cooled air has the property of descending. The air temperature-adjusted at a position above the counter 55 is less likely to flow directly below the counter 55, so for a person who dislikes cold air hitting their face, the counter 55 can block the descending cold air as much as possible. Since the cold air blocked by the counter 55 will descend from the protruding direction side end (and width direction side end) of the counter 55, it will be easier to flow to the toe side rather than the head of the user P.

[0266] On the other hand, the warmed air has the property of ascending. The air temperature-adjusted at a position below the counter 55 and above the mirror 56 is less likely to flow directly above the counter 55, so for a person who wants to prevent warm air from escaping, the counter 55 can suppress the escape of the ascending warm air as much as possible. By closing the open portions at both width direction ends of the counter 55 and the mirror 56, the warm air will be even less likely to escape. Note that the warm air temperature-adjusted at a position below the mirror 56 will rise along the mirror 56 and gradually rise and diffuse from the protruding direction side end of the counter 55.

[0267] The air conditioning system of the room space 1 in this embodiment as described above can contribute not only to the air conditioning of the entire room space 1 but also to the formation of a good sleeping environment in the bed 10 with one end 10a placed closer to the first wall portion 4a. In addition, a mirror 56 is provided on the lower surface of the counter 55, enabling the adjustment of the illuminance in the space below the counter 55. As a result, even if the space below the counter 55 becomes a dimly lit space in the shadow of the counter 55, the space below the counter 55 can be brightened, contributing to the formation of a good waking-up environment.

[0268] According to this embodiment, the following excellent effects can be achieved. That is, since the radiant heating and cooling device 12 is incorporated and supported in the wall portion 4 to which the counters 49, 53, 55 are attached, in addition to heating or cooling the objects located nearby by the direct radiant heat from the radiant heating and cooling device 12, the air (cool air) whose temperature is adjusted by the radiant heating and cooling device 12 at a position above the counters 49, 53, 55 can be made to descend from the protruding direction side end along the upper surface of the counters 49, 53, 55, or the air (warm air) whose temperature is adjusted by the radiant heating and cooling device 12 at a position below the counters 49, 53, 55 can be made to stay on the lower surface of the counters 49, 53, 55 without allowing the air to escape. Thereby, a comfortable thermal environment can be formed in the room space 1 by utilizing the air whose temperature is adjusted by the radiant heating and cooling device 12. Furthermore, since the counters 49, 53, 55 are provided with illuminance increasing means 50, 51, 54, 56 for increasing the illuminance in the space below the counters 49, 53, 55, even if the space below the counters 49, 53, 55 becomes a dimly lit space in the shadow of the counters 49, 53, 55, the space below the counters 49, 53, 55 can be brightened by the illuminance increasing means 50, 51, 54, 56. Thereby, a sleep environment (waking-up environment) that is easy to wake up from the viewpoint of illuminance can be formed.

[0269] In addition, since the illuminance increasing means 50 and 51 are lighting devices 50 and 51 provided on the lower surface side of the counter 49, as dedicated devices having the function of brightening the illuminated portion, the space below the counters 49, 53, and 55 can be directly brightened. As a result, it becomes easier to form a sleep environment that is easy to wake up from the perspective of illuminance.

[0270] Further, the counter 49 has a lighting storage portion 52 for storing the lighting device 51 and arranging the lighting device 51 below the lower surface of the counter 49. Since a gap is formed between the lower surface of the counter 49 and the lighting storage portion 52, the space below the counters 49, 53, and 55 can be brightened by the light leaking from the gap. That is, since the lighting device 51 stored in the lighting storage portion 52 can function as indirect lighting, unlike the case of being illuminated by direct light, the space below the counter 49 can be illuminated with soft light reflected on the lower surface of the counter 49 or the like.

[0271] In addition, since the illuminance increasing means 54 is a monitor 54 provided on the lower surface of the counter 53 for displaying an image, the space below the counter 53 can be brightened while displaying the image. As a result, it becomes easier to form a sleep environment that is easy to wake up from the perspective of illuminance. Furthermore, depending on the displayed image, it is possible to eliminate the sense of oppression caused by the presence of the counter 53 for the user P who uses the space below the counter 53.

[0272] Further, the mirror 56 provided in an inclined state on the lower surface of the counter 55 is arranged such that the mirror surface faces the side opposite to the wall portion 4 and obliquely downward. Therefore, light taken in from the outside of the space below the counter 55 reaches the user P who uses the space below the counter 55. As a result, if the room space 1 is darkened at bedtime, it is difficult for light to reach the user P who uses the space below the counter 55. However, in the morning, natural light that enters the room space 1 from the outside is likely to reach the user P who uses the space below the counter 55, making it easier to form a sleep environment that is easy to wake up from from the perspective of illuminance. Furthermore, since the user P who uses the space below the counter 55 can see the outside of the space below the counter 55 through the mirror 56, it is possible to relieve the sense of oppression caused by the presence of the counter 55 on the user P who uses the space below the counter 55.
