Description

The present invention relates to radiant air conditioners.

2. Description of the Related Art Conventionally, a convection system has been generally used as an air conditioner for maintaining a comfortable indoor environment. This is a method of air conditioning by blowing out conditioned air with adjusted temperature and humidity into the room and by convection.
However, the convection system tends to make people feel dissatisfied in terms of comfort.
One of the reasons for this is that when air convections, a difference in temperature distribution occurs between the upper and lower parts of the room, warm air tends to go to the ceiling, and cold air tends to stay on the floor. It's good for health, and it's the opposite of cold feet and hot feet, which people feel comfortable, so they can't help but feel uncomfortable.
Another cause of dissatisfaction is the occurrence of a so-called draft, in which convection air currents hit the human body directly. For example, in an air-conditioned room, it is said that the sensible temperature drops by 3°C at a wind speed of 0.5m. For this reason, when entering an air-conditioned room from outdoors in the scorching sun, one feels comfortable at first, but after the body cools down, it actually feels cold.
Moreover, there are many people who feel uncomfortable with the fact that the airflow continues to hit the body directly.

A radiant air conditioner overcomes the above disadvantages of a convective air conditioner in that the air flow does not directly hit the body.
As an example of such a radiant air conditioner, Patent Document 1 discloses an air conditioner in which an air conditioner and a radiant panel are attached to the ceiling surface (Patent Document 1 calls it a "radiant air conditioning system"). .
The radiation panel has a structure in which an air passage is formed between a moisture-permeable radiation panel and a heat insulating panel facing each other, and the inlet of the air passage faces the outlet of an air conditioner (Patent Document 1. paragraphs [0025] to [0029], see FIGS. 1 to 11). Therefore, the conditioned air blown out from the outlet of the air conditioner is introduced into the air passage and circulates in the air passage. This controls the temperature of the radiant panel and provides radiant cooling and heating.

JP 2016-217630 A

Patent document 1 illustrates a thin air conditioner whose height is low in the vertical direction (see FIGS. 11 to 5 of document 1). Regarding this air conditioner, Patent Document 1 describes that "the air in the indoor space 1 is taken in and cooled or heated by the heat absorption or heat dissipation action accompanying the phase change of the heat transfer fluid, and the cooled or heated air is discharged from the air conditioning air outlet 211a. It is designed to erupt from" (see paragraph [0027] of Document 1). On the other hand, there is no explanation about the internal structure of the air conditioner, and the details are unknown.

A cross-flow fan is widely used as an air blowing source for an air conditioner. A cross-flow fan can blow conditioned air evenly from a wide blow-out port, and the operation noise is low, so it is suitable for use as a blowing source of an air conditioner.

Therefore, it is assumed that the air conditioner described in Patent Document 1 also uses a cross-flow fan.

However, in order for the cross-flow fan to perform normal air blowing operation, the air flow path in the air conditioner from the air intake to the air outlet (hereinafter also referred to as the "air flow path") must be bent. . For this reason, a relatively large space is required for arranging the in-machine flow path, and there are also restrictions on the layout of the air intake port and the air outlet port.

When a cross-flow fan is used in the thin air conditioner described in Patent Document 1, it is difficult to obtain a sufficient height dimension in the vertical direction in the housing of the air conditioner. We have to think about how to secure it and lay out the in-flight flow path. In other words, the problem is how to reduce the height of the air conditioner while using the cross-flow fan as the air blowing source.

SUMMARY OF THE INVENTION An object of the present invention is to reduce the height dimension of an air conditioner using a cross-flow fan as an air blowing source.

The air conditioner of the present invention comprises a housing in which an air intake port and a blowout port are arranged on one surface where horizontal planes intersect and one surface on the opposite side, respectively; an exchanger, a cross-flow fan disposed closer to the blowout port than the heat exchanger, and a rotation direction of a region above a rotating shaft is the direction from the heat exchanger toward the blowout port. and a drive unit for driving the drive source of the cross flow fan.

I have it.

According to the present invention, the height dimension of the air conditioner can be reduced even if the cross-flow fan is used as the air blowing source.

Radiant Air Conditioner As shown in FIG. 1, the radiant air conditioner 11 of the present embodiment comprises an air conditioner 51 and a radiant panel unit 101 both installed on the ceiling surface C. FIG. The radiant air conditioner 11 is arranged close to the wall surface W provided on one side of the room R. As shown in FIG.

In this embodiment, the directions of the air conditioner 51 and the radiation panel unit 101 are defined as follows. First, consider the horizontal plane. This horizontal plane is not a horizontal plane that can exist as a tangible object, but an abstract and conceptual virtual horizontal plane.

The one surface intersecting with such a horizontal plane and the opposite one surface are defined as the rear surface and the front surface of the air conditioner 51 . The rear surface is a surface on which an air intake port 52, which will be described later, is arranged (see FIGS. 1 and 3). The front surface is a surface on which an air outlet 55, which will be described later, is arranged (see FIGS. 1 and 4).
When the air conditioner 51 is viewed from the front side, the plane that intersects with the horizontal plane is the side surface. The right side becomes the right side and the left side becomes the left side.
Regarding the upper and lower surfaces of the air conditioner 51, the vertically upper surface is the upper surface, and the vertically lower surface is the lower surface.
When the air conditioner 51 is viewed from the front side, the direction connecting both sides is defined as the width direction (width direction), the direction connecting the front surface and the rear surface is defined as the depth direction, and the direction connecting the upper surface and the lower surface is defined as the height direction. The front side is also called the front side, and the rear side is called the back side.

As shown in FIG. 1, the radiant panel unit 101 is arranged in a position adjacent to the front of the air conditioner 51 . When maintaining such an arrangement relationship, each surface (end portion) and direction of the radiant panel unit 101 are also defined in the same manner as the above-described surface and direction of the air conditioner 51 . The face (edge) and direction of the radiant panel unit 101 defined in this manner are uniquely determined, and will not change even if the layout relationship shown in FIG. 1 in which the radiant panel unit 101 is adjacent to the air conditioner 51 is broken.
Regarding the fact that it conforms to the air conditioner 51, the housing 51a of the air conditioner 51 described later, the panel base 111 (the rear panel 112, the side wall 113) and the radiation panel 131 (the frame 132, the cloth cover 141) constituting the radiation panel unit 101 are included. is similar to that of the radiation panel unit 101. 1 in which the radiation panel unit 101 is adjacent to the front of the air conditioner 51, the planes (edges) and directions of the respective parts are defined in the same manner as the planes and directions described for the air conditioner 51. be. The surfaces (ends) and directions of the above-described portions defined in this manner are uniquely determined, and will not change even if the arrangement relationship shown in FIG.

(1) Air Conditioner The ceiling surface C is a raised ceiling and has a depression C1 (see also FIGS. 18 and 19). The air conditioner 51 is attached by, for example, hanging bolts so as to fit into the recess C1 (see FIG. 18).
As shown in FIG. 1, the air conditioner 51 takes in the air in the room R from the air intake port 52 provided on the rear surface, contacts the heat exchanger 53, and then air-conditions the air from the air outlet 55 by the cross-flow fan 54. Blow out as air. A filter 56 is detachably attached to the air intake 52 .

(a) Appearance As shown in FIGS. 2 to 6, the housing 51a of the air conditioner 51 has a thin shape whose dimensions decrease in order of width, depth, and height.

As shown in FIG. 3, the air intake port 52 arranged on the rear surface of the housing 51a has three horizontally long rectangular regions arranged in parallel in the horizontal direction. The individual air intake ports 52 are opened in their respective regions to connect the space on the room R side with the internal space of the housing 51a.
A filter 56 is attached to each of the three regions of the air intake port 52 . These filters 56 are attached to the housing 51a so that they can be inserted and removed by working from the bottom side. The housing 51a has a structure in the rear side area that allows the filter 56 to be attached by being pushed upward from below and removed by being pulled downward from above. This structure includes a structure that guides the filter 56 in the vertical direction and a structure that holds the filter 56 at a position that closes the air intake port 52 .
The three regions forming the air intake port 52 are arranged close to the right side surface of the housing 51a (see FIGS. 2 and 5). Therefore, when viewed from the back side, these three areas are shifted to the left.

As shown in FIG. 4, the outlet 55 arranged on the front surface of the housing 51a has three horizontally long rectangular regions arranged in parallel in the horizontal direction. These three areas are aligned with the three areas that form the air intake port 52 and are arranged on the right side in the width direction of the housing 51a (see FIGS. 2 and 5).

The number of three outlets 55 and the arrangement of the outlets 55 to the right are merely an embodiment. The implementation is not limited to this, and the outlet 55 may not be partitioned into a plurality of regions, or may be partitioned into two regions or four or more regions. The blowout port 55 may be arranged closer to the left side of the housing 51a, or may be arranged in the center. It is not essential that the air intake port 52 and the blowout port 55 are arranged on the same side surface of the housing 51a. can be changed.

As shown in FIGS. 2 and 4 to 6, the outlet 55 is provided at the tip of a hood 61 projecting from the front of the housing 51a. The three regions of the blowout port 55 are partitioned by partition plates 62 provided vertically within the hood 61 . If the outlet 55 is not divided into a plurality of areas, the partition plate 62 is unnecessary.
An inclined surface 63 is formed on the base side of the upper surface of the hood 61 that communicates with the front surface of the housing 51a. Such an inclined shape is applied not only to the outer surface of the hood 61 but also to the inner surface (see FIG. 9).
The air conditioner 51 fitted in the recess C1 of the ceiling surface C has a hood 61 projecting toward the panel base 111 from the edge E forming the boundary between the ceiling surface C and the recess C1. At this time, the inclined shape of the inclined surface 63 of the hood 61 contributes to smooth connection with the panel base 111, which will be described later.
The inclined shape of the inclined inner surface 64 of the hood 61 contributes to ensuring normal operation of the cross-flow fan 54, which will be described later.
Contributions of these inclined surfaces 63 and inclined inner surfaces 64 will be described later.

As shown in FIGS. 2 to 6 and 8, rails 57 are attached to both side surfaces of the housing 51a of the air conditioner 51. As shown in FIGS. The mounting position of the pair of rails 57 is on the rear side of the housing 51a and relatively lower.
As shown in FIG. 7, the rail 57 extends along the arrangement direction (depth direction) of the air conditioner 51 and the panel base 111 and has a stepped portion 57a. The step portion 57a has a lower height on the panel base 111 side and a higher height on the air conditioner 51 side.
A pair of left and right rails 57 are used to attach the radiant panel unit 101 to the radiant air conditioner 11 . Details will be described later.

As shown in FIGS. 3, 5 to 6, and 8, a pair of magnets MG are provided on both end sides of the rear surface of the housing 51a of the air conditioner 51. As shown in FIGS.
As shown in FIG. 8, the housing 51a has a magnet holder 71 protruding from its rear surface. The magnet MG is attached to the bottom surface of the magnet holder 71 .
A pair of left and right magnets MG are used to attach the radiant panel unit 101 to the radiant air conditioner 11 . Details will be described later.

(b) Internal Structure Referring to FIG. 9, the air inlet 52 provided on the rear side of the housing 51a and the air outlet 55 provided on the front side thereof are arranged on one surface where horizontal planes intersect and one surface on the opposite side. I understand.
The housing 51 a has a heat exchanger 53 arranged between the air inlet 52 and the air outlet 55 , and a cross-flow fan 54 located closer to the air outlet 55 than the heat exchanger 53 . The air intake port 52, the heat exchanger 53, the cross-flow fan 54, and the blow-out port 55 are provided on a straight line in the depth direction.
The cross-flow fan 54 rotates around the rotation axis A. Inside the housing 51a, the cross flow fan 54 rotates to take in air from the room R through the air intake port 52, bring the taken in air into contact with the heat exchanger 53, and blow out the air from the blowout port 55. A channel (hereinafter also referred to as an “in-machine channel 81”) is provided.

The cross-flow fan 54 does not perform the desired operation, that is, the operation of sucking air from the air intake port 52 and discharging it from the air outlet 55 if it is simply placed in the in-machine flow path 81 . In order to generate an airflow in such a direction (see arrows in FIG. 9),
- The in-machine passage 81 is curved. - The cross-flow fan 54 is arranged at a predetermined position in the in-machine passage 81. The condition of rotation must be met.
Therefore, in the present embodiment, a structure for rotating the cross-flow fan 54 in a predetermined direction and an airflow adjusting section 82 for generating an airflow from the air intake port 52 to the blow-out port 55 by such rotation of the cross-flow fan 54 are provided. and
explain in detail.

(Rotating direction of cross flow fan)
As shown in FIGS. 2 to 5, the housing 51a of the air conditioner 51 has the air intake port 52 and the air outlet port 55 arranged to the right. As a result, a space is created on the left side of the housing 51 a that is not affected by the flow of air connecting the air intake port 52 and the blowout port 55 . The air conditioner 51 has an electrical structure arranged in this space.
As shown in FIG. 9, the electrical structures are a drive unit DR and a control unit CR that drive the motor M that is the driving source of the cross flow fan 54 . The controller CR controls all operations of the air conditioner 51, including the operation of the drive unit DR.
The drive unit DR controlled by the control unit CR drives the cross flow fan 54 so as to rotate clockwise in FIG. The clockwise direction in FIG. 9 is the direction in which the upper half side of the cross flow fan 54 , that is, the direction of rotation of the region above the rotation axis A is directed from the heat exchanger 53 to the outlet 55 .

(Shape of internal flow path and placement of cross-flow fan)
As shown in FIG. 10, the heat exchanger 53 has refrigerant pipes 53b passing through a plurality of vertically arranged aluminum plates 53a. By passing the refrigerant through the refrigerant pipes 53b, the temperature of the refrigerant is heat-conducted to the aluminum plates 53a, and the temperature of the air passing through the slits 53c formed between the individual aluminum plates 53a is adjusted.
The heat exchanger 53 of this embodiment has three layers. That is, three single-layer heat exchangers 53 forming one unit are directly arranged.
Moreover, the three-layer heat exchanger 53 is fixed in the housing 51a in an inclined state. The direction of inclination is the direction in which the surface on the cross flow fan 54 side faces downward.

As shown in FIG. 9, the air passing through the slits 53c of the heat exchanger 53 travels in a direction orthogonal to the surface of the heat exchanger 53. As shown in FIG. As a result, an airflow is generated obliquely downward from the heat exchanger 53 .
The airflow adjustment unit 82 directs the air that is directed downward perpendicular to the surface of the heat exchanger 53 along the bottom surface of the housing 51a, and causes the cross-flow fan 54 to suck up the air that has flowed along the bottom surface. The sucked air goes toward the cross flow fan 54 from diagonally below.
In order to generate such an air flow, the air conditioner 51 is provided with two air flow adjustment plates 83 around the cross flow fan 54 so that the traveling direction of air from the heat exchanger 53 obliquely downward is obliquely upward. It is converted into an airflow directed obliquely downward to the cross-flow fan 54 . The two airflow adjustment plates 83 are arranged so as to sandwich the crossflow fan 54 from above and below with a small gap, so that the airflow from obliquely below is introduced into the crossflow fan 54. there is
The two upper and lower airflow adjustment plates 83 further form an in-machine flow passage 81 on the side of the outlet 55 with respect to the cross-flow fan 54 so as to be inclined obliquely downward. As a result, the in-machine passage 81 generates an air current from the cross-flow fan 54 obliquely downward at the outlet 55 .
More specifically, the in-machine channel 81 bends the air introduced into the cross flow fan 54 from the heat exchanger 53 side by 90° and guides it to the blowout port 55 side. As a result, the operation of the cross-flow fan 54 to suck air from the air intake port 52 and discharge it to the air outlet 55 is performed normally.
The inclined inner surface 64 of the hood 61 described above has a shape inclined obliquely downward. The inclined inner surface 64 having such a shape forms part of the in-machine flow path 81 closer to the outlet 55 than the cross-flow fan 54 and contributes to ensuring the normal operation of the cross-flow fan 54 .

(2) Radiation Panel Unit The radiation panel unit 101 is composed of the panel base 111 and the radiation panel 131 .

(a) Panel Substrate As shown in FIG. 11, the panel substrate 111 is a heat insulating member having a pair of side walls 113 raised from both sides of a flat rectangular rear panel 112 . For example, expanded polystyrene (EPS), resin, gypsum, urethane, glass wool, rock wool, or the like can be used as the material of the panel substrate 111 .
The pair of side walls 113 are raised from both end portions in the long side direction (width direction) of the rear panel 112, that is, from both side ends, and slightly wrap around in the width direction along the long side. Due to such a shape, three sides of the pair of side walls 113, ie, the area on one end side, the area on the other end side, and the area facing the back panel 112 are open.
For convenience of explanation, the region on one end side of the pair of side walls 113 is called inlet 114 , the region on the other end side is called outlet 115 , and the region facing rear panel 112 is called facing region 116 . The facing area 116 is an area within a plane including the upper end surfaces of the pair of side walls 113 .
Therefore, the panel substrate 111 has a rear panel 112 as a substrate, and has side walls 113 as wall portions rising from the rear panel 112 in the form of an enclosure. An inlet 114 and an outlet 115 are provided between the pair of side walls.

The inlet 114 of the panel base 111 has a shape inclined toward the edge communicating with the outlet 55 of the air conditioner 51 . This shape is compatible with the slanted surface 63 of the hood 61 having the outlet 55 at its tip.

The panel substrate 111 having such a structure is attached to the ceiling surface C with the position of the edge forming the introduction port 114 aligned with the position of the edge E forming the boundary between the ceiling surface C and the recess C1. As a result, the inclined surface 63 of the hood 61 of the air conditioner 51 is aligned with the introduction port 114 of the panel base 111, and the blowout port 55 and the introduction port 114 are connected (see FIG. 19).
Any type of means for attaching the panel base 111 to the ceiling surface C may be used. For example, means such as screws, hook-and-loop fasteners, adhesive tapes, and adhesion can be used.

A pair of stoppers 117 are provided on the panel base 111 so as to be positioned at the outlet 115 . As a result, the outlets 115 are distributed at three locations, one at the central side with a wide width and two locations at both sides with a narrow width. These stoppers 117 are configured by stopper fittings 119 fixed to the back panel 112 .
The stopper fitting 119 functions as a connecting tool, and is provided with a connecting groove 119a.

Such a panel substrate 111 is integrally formed of EPS, for example. The whole therefore functions as a heat insulator.

(b) Radiation Panel As shown in FIGS. 12 to 14, the radiation panel 131 is formed by covering a rectangular frame 132 with a bag-shaped fabric cover 141 .

The frame 132 is formed in a rectangular shape by connecting a plurality of rod-like members 133 and having ribs for reinforcement and rotation prevention. A part of the rod-shaped member 133 is used as an outer frame member 133a that is assembled into a rectangular shape that determines the outer shape of the frame 132, and the other part is used as a reinforcing member 133b that reinforces the outer frame. As an example, a prismatic aluminum pipe having a hollow structure is used for the rod-shaped member 133 , and the frame 132 is formed by connecting these with a resin connector or screwing them together.
As another example, the rod-shaped member 133 may be made of resin or made of carbon.
Such a frame 132 has a first frame 134 and a second frame 135 .
The first frame 134 is arranged in a region facing the air conditioner 51 . The width of the first frame 134 is set wider than that of the air conditioner 51 .
The second frame 135 is larger in both the width direction and the depth direction than the panel base 111 in the width direction and the depth direction. It is
The first frame 134 is connected to the rear end of the second frame 135 with a hinge 136 and is rotatable with respect to the second frame 135 (see FIGS. 12 to 13 and 16). The first frame 134 has a size that completely covers the air conditioner 51 together with the rear end portion of the second frame 135 in the depth direction.

As shown in FIGS. 13 and 14, the cloth cover 141 has a bag shape like a futon cover. It has a shape in which four sides are closed and three sides have open edges 142 that can be opened. A chuck 143 is attached to the open edge 142 and can be opened and closed by the chuck 143 . By opening the open edge 142, the frame 132 can be stored. The open edge 142 is positioned slightly inside the edge of the cloth cover 141 .
Such a cloth cover 141 is made of cloth, that is, fibers, and has air permeability and stretchability.
The cloth cover 141 is formed slightly smaller than the frame 132 in its width direction and depth direction, and maintains a stretched state when the frame 132 is housed.
The bag-like shape of the cloth cover 141 can also be regarded as an endless shape when viewed as a shape that wraps around the frame 132 in the width direction. This is because an endless shape with both ends closed becomes a bag shape.

The cloth cover 141 having a bag shape has a structure in which a fiber material on the surface side exposed to the room R side and a fiber material on the back side facing the flow path 151 are sewn together. For convenience of explanation, the fiber material on the front side is called surface fiber 141A (see also FIGS. 29 and 30), and the fiber material on the back side is called back fiber 141B.
The surface fibers 141A are exposed to the room R side when the radiant panel 131 is installed, and determine the external appearance of the radiant air conditioner 11 . Therefore, when selecting the material of the surface fibers 141A, the aesthetic viewpoint is emphasized.
The material of the back surface fiber 141B is selected from the viewpoint of minimizing resistance to the air flow blown from the outlet 55 of the air conditioner 51 when it is guided to the back side of the surface fiber 141A. From this point of view, in the present embodiment, mesh cloth, ie, mesh material fibers, is used as the back surface fiber 141B.
As shown in FIGS. 13 and 14, the surface fibers 141A wrap around to the back surface facing the back panel 112 and are sewn together with the back surface fibers 141B on the back surface side. The cloth cover 141 positions the seam portion SP so that it is aligned with the pair of side walls 113 when the radiation panel 131 is attached to the panel base 111 .

Radiation panel 131 in which frame 132 is covered with fabric cover 141 is covered with fabric cover 141 because first frame 134 and second frame 135 are rotatable about an axis passing through hinge 136 . It is rotatable even when it is stuck. Therefore, for convenience of explanation, of the radiation panel 131, the portion where the cloth cover 141 covers the first frame 134 is referred to as a first panel 131A, and the portion where the cloth cover 141 covers the second frame 135 is referred to as a second panel 131B. call.
The first panel 131A serves as a region facing part of the air conditioner 51 .
The second panel 131</b>B covers the remaining part of the air conditioner 51 and the entire surface of the panel base 111 .

As shown in FIG. 1, the radiation panel 131 is positioned and secured to the facing area 116 of the panel substrate 111 . This defines a space from the inlet 114 to the outlet 115, which serves as a flow path 151 for the conditioned air.
As schematically shown in FIG. 15(a), the radiating panel 131 in which the fabric cover 141 is covered by the frame 132 has one surface made of the surface fibers 141A and the opposite surface made of the back surface fibers 141B. and forming a hollow shape. At this time, the radiating panel 131 creates a state equivalent to having an opening O on the back side because the back fabric 141B of the fabric cover 141 is a mesh cloth. Therefore, the conditioned air flowing through the flow path 151 freely enters the inside of the radiation panel 131 from the rear fiber 141B and comes into contact with the inside of the front fiber 141A. Therefore, the surface fibers 141A, which are naturally air permeable, function as the radiation surface RS.

As described above, the frame 132 of the radiation panel 131 has a larger projected area than the air conditioner 51 and the panel substrate 111 . More specifically, the width of the first frame 134 is set wider than that of the air conditioner 51, and the width and depth of the second frame 135 are set larger than those of the panel substrate 111 in the width and depth directions. there is Therefore, the radiation panel 131 has a horizontal projection area larger than the combined area of the air conditioner 51 and the panel base 111 .
At this time, as schematically shown in FIG. 15(a), the radiation panel 131 is hollow due to the fabric cover 141 covering the frame 132. Therefore, from the above dimensional relationship, the radiation surface RS on the surface fiber 141A side is is wider than the width of the rear panel 112 .
On the other hand, the opening O is narrower than the width of the rear panel 112 which matches the distance between the pair of side walls 113 facing each other. In other words, the pair of side walls 113 are interposed between the rear panel 112 and the radiation panel 131 along the direction in which the conditioned air is blown out from the outlet 55 of the air conditioner 51, and are interposed without protruding the opening O. facing each other. Thus, the width of the conditioned air passage 151 is defined by the pair of side walls 113, and communicates with the internal space of the radiation panel 131 without leaking the conditioned air from the opening O to the outside.

As schematically shown in FIG. 15( b ), a rod-like member 133 of a frame 132 is positioned in the internal space of the radiation panel 131 . Out of these rod-shaped members 133, the outer frame member 133a of the first frame 134 and the outer frame member 133a of the second frame 135 are positioned directly below the heat exchanger 53 incorporated in the air conditioner 51 in the vertical direction. . The housing 51a of the air conditioner 51 has a flat bottom surface, and the frame body 132 is brought into close contact with the cloth cover 141 interposed therebetween.
Of the first frame 134 and the second frame 135 that are in close contact with the lower surface of the housing 51a, the outer frame member 133a of the second frame 135 that is connected to the first frame 134 functions as a rod-like contact member RM. . The rod-shaped contact member RM is a part of the outer frame member 133a and is brought into close contact with the housing 51a of the air conditioner 51 via the cloth cover 141. As shown in FIG. It is the lower surface of the housing 51a that comes into close contact. A structure for bringing a part of the outer frame member 133a, which is the contact member RM, into close contact with the housing 51a will be described later.
Such a close contact member RM partitions the internal space of the radiation panel 131 and prevents conditioned air from entering the rear side of the air conditioner 51 (the side of the air intake port 52 ) relative to the heat exchanger 53 .

(c) Attachment/detachment structure of radiation panel to panel base As shown in FIGS. 12 to 14 and FIGS. , a pair of sliders 137, a pair of connecting pins 138 as members to be connected, and a pair of adsorption plates 139 as members to be adsorbed are provided.

A pair of sliders 137 are parts for temporarily fixing the radiation panel 131 in cooperation with the pair of rails 57 described above.
A pair of connecting pins 138 are components for permanently fixing the radiation panel 131 in cooperation with the stopper 117 described above.
The pair of attraction plates 139 are components for holding the first panel 131A of the radiation panel 131 in cooperation with magnets MG, which will be described later.

(Temporary fixing structure of radiation panel)
As shown in FIGS. 2 to 5, 7 to 8, 12 to 14, 16(a) and 17, the temporary fixing structure of the radiation panel 131 consists of a pair of rails 57 and a pair of sliders 137. It is composed by
The pair of sliders 137 are fixed to the outer frame members 133a forming the contact members RM of the second frame 135, respectively. The fixed positions are positions near both ends of the outer frame member 133a.
The slider 137 has a round bar-shaped pin 137b fixed to a sheet metal 137a for screwing to the outer frame member 133a. The metal plate 137a positions the pin 137b at a position higher than the outer frame member 133a. The pins 137b are arranged along the width direction of the radiation panel 131, that is, along the direction of the rotation axis of the first frame 134 and the second frame 135. As shown in FIG.

The distance between the pins 137b of the pair of sliders 137 is set slightly wider than the width of the housing 51a of the air conditioner 51. As shown in FIG. Therefore, it becomes possible to guide the pair of sliders 137 from above the pair of rails 57 and place the pins 137b on the rails 57 (see FIGS. 20 and 21).
The pin 137b placed on the rail 57 is slidable on the rail 57. As shown in FIG. At this time, the pin 137b climbs over the stepped portion 57a and changes the height of the slider 137, in other words, the height of the radiation panel 131. FIG. When the slider 137 moves from the panel substrate 111 side to the air conditioner 51 side, the radiation panel 131 is positioned at a high position. When the slider 137 moves from the air conditioner 51 side to the panel base 111 side, the radiation panel 131 is positioned at a low position. The radiation panel 131 positioned at a high position brings the outer frame member 133a of the second frame 135, which is the contact member RM, into close contact with the housing 51a of the air conditioner 51 through the fabric cover 141. As shown in FIG.

As shown in FIGS. 2 to 5 and 7 to 8, each end of the rail 57 is provided with a regulating piece 57b. These restricting pieces 57b prevent the pin 137b sliding on the rail 57 from falling off.

(Main fixing structure of radiation panel)
As shown in FIGS. 11 to 14 and 16(b), the permanent fixing structure of the radiation panel 131 is composed of a pair of stoppers 117 and a pair of connecting pins 138. As shown in FIG.
A pair of connecting pins 138 are fixed to the second frame 135 . The fixed position is a pair of reinforcing members 133b connected to the outer frame member 133a on the side opposite to the side connected to the first frame 134. As shown in FIG. Among these reinforcing members 133b, the connecting pin 138 is attached at a relatively close position to the outer frame member 133a.
The pair of connecting pins 138 have the form of studs that fit into the connecting grooves 119 a of the pair of left and right stoppers 117 provided on the panel base 111 . The connecting groove 119a is located at the outlet 115 of the radiation panel unit 101 and opens toward the room R side. Therefore, the connecting pin 138 is fitted into the connecting groove 119 a of the stopper 117 by horizontally moving the radiation panel 131 from the panel base 111 toward the air conditioner 51 .
Therefore, the stopper 117 and the connecting pin 138 constitute a connecting portion CN that detachably connects the air conditioner 51 and the panel base 111 in accordance with the movement in the arrangement direction (depth direction).

(Holding structure of the first panel)
As shown in FIGS. 1, 3, 5, 8, 12 to 14, and 16(a), the holding structure for the first panel 131A includes a pair of magnets MG (panel holders) and a pair of attracting magnets MG (panel holders). It is configured by a plate 139 (member to be attracted).
The pair of suction plates 139 are fixed to two reinforcing members 133b provided on the first frame 134, respectively. The fixed position is a position slightly lower than the pin 137b of the slider 137 when the first frame 134 and the second frame 135 are arranged in the same plane. These suction plates 139 position flat plate-shaped suction surfaces 139a horizontally while the first frame 134 stands horizontally.
As described above, the pair of magnets MG are provided on both end sides of the back surface of the air conditioner 51 and attached downward.
When the radiation panel 131 is fully fixed and the first panel 131A is raised horizontally, the attraction surface 139a of the attraction plate 139 faces the magnet MG and is attracted by magnetic force. It is positioned as

(Invention of cloth cover)
By providing a structure for attaching and detaching the radiation panel 131 to the panel substrate 111, the frame body 132 of the radiation panel 131 is uneven. They are the slider 137 , the connecting pin 138 and the suction plate 139 .
If the cloth cover 141 were to cover the frame 132 together with these parts, not only would the work of attaching and detaching the cloth cover 141 to and from the frame 132 become complicated, but it would also be difficult to allow these parts to function normally. I can't.
Therefore, the cloth cover 141 has openings for exposure at the slider 137, the connecting pin 138, and the suction plate 139 so that these parts can be exposed. The illustration of the opening for exposure is omitted.

2. Installation Procedure The installation procedure of the radiant air conditioner 11 will be described.

(1) Installation of Air Conditioner First, as shown in FIG. 18, the air conditioner 51 is installed in a recess C1 provided in the ceiling surface C which is a raised ceiling.
If the recess C1 is provided in advance, it is used, and if the recess C1 is not provided, the ceiling surface C is constructed to create the recess C1.

(2) Mounting of Panel Substrate As shown in FIG. 19, the panel substrate 111 is attached to the ceiling surface C.
The panel substrate 111 is aligned and fixed to the ceiling surface C so that the inlet 114 is positioned at the edge E forming the boundary between the ceiling surface C and the recess C1.
At this time, the inlet 114 of the panel base 111 is positioned along the edge E forming the boundary between the ceiling surface C and the recess C1. As a result, the outlet 55 of the air conditioner 51 and the inlet 114 of the panel base 111 are aligned and communicated with each other (see also FIG. 1).

(3) Installation of Radiation Panel (a) Temporary Fixing First, the radiation panel 131 is temporarily fixed.
As shown in FIGS. 20 to 22, a pair of sliders 137 provided on the radiation panel 131 are brought close to the rails 57 provided on both sides of the air conditioner 51, and the sliders 137 are placed on the rails 57, so that the radiation panel 131 can be temporarily moved. be stopped. The slider 137 is placed on a low place located on the near side of the rail 57 .
In the temporarily fixed radiating panel 131, the positions of the second frame 135 and the first frame 134 are not constrained and are rotatable.

(b) Rotation of the Second Panel As shown in FIGS. 23 and 24, once the radiation panel 131 is temporarily fixed, the second panel 131B is rotated to be horizontal.
At this time, the pair of sliders 137 are mounted on a place where the height of the pair of rails 57 is low. The connecting pin 138 of the second panel 131B faces the stopper fitting 119 of the panel base 111 with a gap therebetween.

(c) Final fixation As shown in FIGS. 25 and 26, when the second panel 131B is leveled, the second panel 131B is pushed in while maintaining the posture. That is, the radiation panel 131 is moved toward the air conditioner 51 .
As a result, the connecting pin 138 is fitted into the connecting groove 119a of the stopper fitting 119, and the radiation panel 131 is permanently fixed.
At this time, the slider 137 slides on the rail 57, climbs over the stepped portion 57a, and is positioned at a high position. As a result, the tip side of the radiation panel 131 , that is, the end side of the second panel 131 B connected to the first panel 131 A is lifted and pressed against the lower surface of the housing 51 a of the air conditioner 51 . As a result, the outer frame member 133a serving as the contact member RM of the second frame body 135 comes into close contact with the lower surface of the housing 51a through the cloth cover 141. As shown in FIG.
The first panel 131A freely rotates by the hinge 136 and hangs vertically when the radiating panel 131 is fully fixed.

(d) Holding the First Panel As shown in FIGS. 27 to 30, the first panel 131A is rotated to be horizontal.
Then, the attracting surface 139a of the attracting plate 139 provided on the first panel 131A is magnetically attracted to the magnet MG provided on the back surface of the air conditioner 51, and the cloth cover 141 is attracted to the magnet MG. This holds the first panel 131A and keeps it horizontal.
By maintaining the horizontal state of the first panel 131A, the cloth cover 141 is pulled by the first frame 134 and kept in a stretched state.
Thus, the installation work of the radiation panel 131 is completed.

(4) Removal of Radiation Panel (a) Releasing Hold of First Panel As shown in FIG. 29, the first panel 131A is rotated against the attraction force of the attraction plate 139 due to the magnetic force of the magnet MG.
Then, as shown in FIGS. 25 and 26, when the hand is released, the first panel 131A rotates freely and hangs vertically.

(b) Uncoupling of Coupling Portion The second panel 131B is grasped and pulled so that the state shown in FIG. 25 changes to the state shown in FIG. That is, the radiation panel 131 is moved from the air conditioner 51 toward the panel base 111 .
As a result, the connecting pin 138 falls out of the connecting groove 119a of the stopper metal fitting 119, and the permanent fixation of the radiation panel 131 is released.
At this time, the slider 137 slides on the rail 57, climbs over the stepped portion 57a, and is positioned at a low position. As a result, the tip side of the radiating panel 131, that is, the position of the edge side of the second panel 131B connected to the first panel 131A is also lowered and separated from the lower surface of the housing 51a of the air conditioner 51. FIG. As a result, the state in which the outer frame member 133a, which serves as the contact member RM of the second frame body 135, is in close contact with the lower surface of the housing 51a via the cloth cover 141 is released, and the radiation panel 131 is temporarily fixed.

(c) Rotation of Second Panel As shown in FIGS. 21 and 22, the second panel 131B is rotated with the pin 137b of the slider 137 placed on the rail 57 as a starting point to be in an inclined state.

(d) Detachment Both ends of the second panel 131B are gripped, and the slider 137 is lifted from the rail 57 to be detached.
This completes the work of removing the radiation panel 131 .

3. Effects When the air conditioner 51 is operated, conditioned air blows out from the outlet 55 and flows from the inlet 114 to the outlet 115 through the flow path 151 . Then, the temperature of the radiation panel 131 is adjusted by the conditioned air. It is heated during heating and cooled during cooling. As a result, the room R is radiantly air-conditioned.

(1) Prevention of Dew Condensation During cooling, the radiant air conditioner 11 of the present embodiment suppresses dew condensation on the radiant panel 131 .
The reason is explained in detail.

(a) Cause of Condensation Moisture is contained in the air as gas (water vapor).
The state in which the air contains water vapor to the limit is called a saturated state, and the amount of water vapor at this time is called the saturated water vapor amount. The amount of saturated water vapor fluctuates depending on the temperature, and the higher the temperature, the lower the amount.
As the air cools down, the moisture, which was in the form of water vapor while the temperature was high, eventually saturates and changes to a liquid. In other words, as the temperature drops, the amount of saturated water vapor also decreases, so if the air continues to be cooled, at some point the water vapor will become saturated and the air will turn into a liquid.
The temperature at this time is called the dew point temperature.
The dew point temperature fluctuates according to the amount of water vapor contained in the air.
In a more concrete phenomenon, saturated water vapor condenses when the temperature falls below the dew point temperature and adheres to the surface of an object as water droplets. This is a phenomenon called dew condensation.
At this time, even if the air temperature drops from the same temperature as the starting point, the temperature at which dew condensation occurs is lower when the amount of water vapor contained is less than when the amount of water vapor contained is large. For example, when the temperature begins to drop in an environment of 25°C, dew condensation occurs at about 14°C when the water vapor content is 50% of the saturated water vapor content, whereas dew condensation occurs when the water vapor content is only 30%. is about 6.5°C.

(b) Radiant Air Conditioner of the Present Embodiment In the radiant air conditioner 11 of the present embodiment, on the back side partitioned by the radiant panel 131, that is, on the side of the flow path 151 where the air conditioner 51 is arranged, the air conditioner Drying of the air is accelerated by the cooling operation of 51, and dry air is circulated. This is because the air in the room R taken into the air conditioner 51 from the air intake port 52 is rapidly cooled when passing through the heat exchanger 53, and part of the water vapor contained in the air is liquefied and removed. be.
Therefore, even if the amount of saturated water vapor is reduced by being cooled by the cooling operation, the dew point temperature of the air passing through the flow path 151 of the conditioned air is lowered by drying, so dew condensation does not occur on the rear surface of the radiation panel 131.例文帳に追加More specifically, no dew condensation occurs on the back surface fibers 141B in the fabric cover 141, nor on the surface fibers 141A that wrap around to the back surface side.
On the other hand, the surface side of the radiant panel 131 is cooled by the cooling operation, and the air in the room R is radiatively cooled. For this reason, the cloth cover 141 located on the surface of the radiation panel 131, that is, the surface fibers 141A are maintained at a low temperature, and the air in contact with the surface fibers 141A approaches the dew point temperature.
At this time, when the air in contact with the surface fibers 141A reaches the dew point temperature, the water vapor contained in the air tends to turn into a liquid.

(c) Principle of Prevention of Dew Condensation On the other hand, in the present embodiment, the cloth cover 141 has air permeability.
Therefore, the air passing through the conditioned air flow path 151 passes through the cloth cover 141 and leaks out to the surface side of the surface fibers 141A exposed to the room R side. As a result, dry air forms a layer on the surface side of the surface fibers 141A.
Therefore, on the front side of the surface fibers 141A where the dry air forms a layer, the dew point temperature of the air is lower than the lowered temperature of the surface fibers 141A, so no dew condensation occurs.
Based on the above principle, according to the present embodiment, it is possible to prevent dew condensation from forming on the surface of the radiation panel 131 in various environments during cooling.

(2) Thinner Air Conditioner (a) Cross Flow Fan The air conditioner 51 uses a cross flow fan 54 as an air blowing source. When the cross-flow fan 54 is used, the height of the housing 51a tends to increase due to the need to bend the in-machine flow path 81 .
On the other hand, the air conditioner 51 of the present embodiment is provided with an airflow adjusting portion 82 including a three-layered heat exchanger 53 arranged in an inclined manner and a pair of airflow adjusting plates 83, so that the height within the housing 51a is limited. In the dimensions, the internal flow path 81 is bent. As a result, the air intake port 52, the heat exchanger 53, the cross-flow fan 54, and the blowout port 55 can be arranged in a straight line.
Therefore, even if the cross-flow fan 54 is used as the air blowing source, the height dimension of the air conditioner 51 can be reduced. As a result, the radiant air conditioner 11 that hides the air conditioner 51 with the radiant panel 131 along the ceiling surface C can be realized.

(b) Heat Exchanger The heat exchanger 53 has a surface on the side of the cross-flow fan 54 inclined obliquely downward so that the airflow passing through the heat exchanger 53 advances obliquely downward. After that, the airflow is guided by a pair of upper and lower airflow adjusting plates 83 and changes its traveling direction so as to go toward the cross flow fan 54 from obliquely below. Such a so-called V-shaped airflow contributes to the generation of an airflow that allows the crossflow fan 54 to function normally within a small separation distance between the heat exchanger 53 and the crossflow fan 54 .

(3) Heat Exchanger The heat exchanger 53 has three layers. As a result, the area of the aluminum plate 53a that contributes to heat exchange can be increased, and high heat exchange efficiency can be obtained.
On the other hand, the air sucked by the cross flow fan 54 passes through the slit 53c formed between the aluminum plates 53a of the heat exchanger 53. As shown in FIG. Therefore, as the number of layers of the heat exchanger 53 increases, the air resistance increases accordingly, and the amount of conditioned air blown from the air outlet 55 is reduced.
On the other hand, in this embodiment, this problem is solved by inclining the heat exchanger 53 within the housing 51a. As mentioned above, the air passes perpendicular to the plane of the heat exchanger 53 . Therefore, if the number of refrigerant pipes 53b is the same, the area of the slits 53c can be increased by slanting the heat exchanger 53 with respect to the airflow rather than arranging the heat exchanger 53 in a direction orthogonal to the airflow. As a result, air resistance can be reduced accordingly.
Such a tilted arrangement of the heat exchangers 53 brings about another advantage of improving the heat exchange efficiency. This is because the area of the aluminum plate 53a with which the air contacts can be increased by inclining it with respect to the airflow.
As described above, the tilted three-layer heat exchanger 53 produces three effects at the same time.
The first effect is that it contributes to the generation of a V-shaped airflow on the downstream side of the heat exchanger 53, thereby contributing to the generation of an airflow that causes the cross-flow fan 54 to function normally.
The second effect is to reduce the resistance given to the air passing through the slit 53c and to stop the decrease in the amount of conditioned air blown from the blower port 55. FIG.
The third is the effect of increasing the area of the aluminum plate 53a with which the air contacts and enhancing the efficiency of heat exchange.

(4) Expansion of heat radiation area (a) Expansion in width direction As shown in FIG. Formed in space. At this time, the width of the channel 151 is defined by the interval between the pair of side walls 113 provided on the panel base 111 .
At this time, the distance between the pair of side walls 113 is determined by the width of the rear panel 112 . The distance between the pair of side walls 113 facing each other does not extend beyond the width of the rear panel 112 . Therefore, the width of the conditioned air flow path 151 does not extend beyond the width of the rear panel 112 .
In contrast, in this embodiment, a hollow radiation panel 131 is used. The radiation panel 131 expands the internal space from the opening O that contacts the flow path 151 of the air conditioner, and forms a radiation surface RS on the side opposite to the opening O. As shown in FIG. Radiation surface RS has a horizontal projection surface wider than the width of rear panel 112 .
Therefore, according to the present embodiment, the heat radiation area of the radiation panel 131 can be expanded beyond the width of the conditioned air flow path defined by the pair of side walls 113 . As a result, it is possible to obtain heat radiation efficiency greater than the actual size.

(b) Expansion to the region overlapping the air conditioner As shown in FIG. It has a region in which the radiating surface RS is also arranged.
Therefore, the heat radiation area of the radiation panel 131 can be further expanded.
Moreover, the expansion range of the heat radiation area is limited to the area where the contact member RM formed by the outer frame member 133a of the second frame 135 comes into close contact with the housing 51a of the air conditioner 51 via the cloth cover 141. FIG. Since the close contact member RM is arranged directly under the heat exchanger 53 built in the air conditioner 51 in the vertical direction, the entire area up to the close contact member RM is used as a heat radiation area, and the heat radiation efficiency is improved. planned.

(5) Prevention of Shortcut Phenomenon As described above, due to the structure in which the hollow area of the radiation panel 131 is expanded to a position overlapping the air conditioner 51, the conditioned air blown out from the air outlet 55 of the air conditioner 51 It turns around to the back side of 51, that is, the side where the air intake port 52 is provided. At this time, if the conditioned air reaches the rear surface of the air conditioner 51, the conditioned air is taken in from the air intake port 52, causing a so-called shortcut phenomenon. As a result, the operating efficiency of the air conditioner 51 is lowered, so some countermeasures are required.
In this regard, in the present embodiment, the close contact member RM formed by the outer frame member 133a of the second frame 135 blocks the flow of the conditioned air and prevents the shortcut phenomenon from occurring. When the radiant panel 131 is permanently fixed (see FIGS. 27 to 30), the close contact member RM comes into close contact with the housing 51a of the air conditioner 51 via the fabric cover 141, and passes through the inside of the radiant panel 131 to the air conditioner 51. impede the flow of conditioned air toward the rear side of the
Moreover, in this embodiment, when the first panel 131A is placed in a horizontal state (see FIGS. 27 and 30), the cloth cover 141 is pulled by the first frame 134 and kept in a stretched state. As a result, the surface fibers 141A of the cloth cover 141 forming the radiation surface RS are brought into close contact with the close contact member RM, and leakage of conditioned air from between the close contact member RM and the surface fibers 141A is prevented.
Therefore, according to the present embodiment, it is possible to prevent the operation efficiency of the air conditioner 51 from decreasing due to the shortcut phenomenon.

(6) Actions and Effects Resulting from Seat Shape and Structure The cloth cover 141 has a bag shape that accommodates the frame body 132 .
This provides the following effects.
(a) Expansion of heat radiation area One effect is that the radiation panel 131 can be easily made hollow.
As a result, it becomes easy to expand the heat radiation area of the radiation surface RS in the width direction and to the area overlapping the air conditioner 51 .
(b) Facilitating Manufacture Another advantage is that the radiant panel 131 can be easily manufactured by facilitating attachment to the frame 132 .
(c) Elimination of Disadvantages On the other hand, since the conditioned air passes through the two cloth covers 141 from the flow path 151 to the room R, the conditioned air flowing toward the cloth cover 141 on the room R side On the other hand, the cloth cover 141 on the flow path 151 side acts as a resistance. If the resistance is too large at this time, the operation of generating a layer of dry conditioned air in the area of the fabric cover 141 facing the room R will be hindered.
Therefore, in the present embodiment, an opening O is provided in the surface of the cloth cover 141 facing the flow path 151 of the conditioned air, and the opening O is provided with a mesh cloth.
More specifically, a structure is adopted in which the fiber material on the front side exposed to the room R side (surface fiber 141A) and the fiber material on the back side facing the rear panel 112 (back fiber 141B) are sewn together, and the cloth cover 141 is made into a bag. I am trying to form it into a shape. By doing so, the back fiber 141B does not need to form the body of the cloth cover 141, and various materials and forms can be freely adopted. In this embodiment, by using a mesh-like material for the back fabric 141B, the resistance given by the back fabric 141B to the conditioned air flowing from the flow path 151 toward the cloth cover 141 on the R side of the room is reduced.
Moreover, the stitched portion SP between the surface fibers 141A and the back surface fibers 141B is aligned with the side wall 113 . As a result, when the radiating panel 131 is viewed from below, it is possible to prevent the stitched portion SP from being seen through the surface fibers 141A.

(7) Facilitating Attachment/Detachment of Radiation Panel According to the present embodiment, when attachment/detachment of the radiation panel 131, the radiation panel 131 can be temporarily fixed in an oblique state. After that, the radiation panel 131 is leveled and moved as it is, so that the radiation panel 131 can be permanently fixed.
Therefore, it is possible to facilitate the attaching and detaching work of the radiation panel 131 .
At this time, in this embodiment, the radiation panel 131 is divided into the first panel 131A and the second panel 131B. Focus your attention on 131A only. Therefore, the attachment and detachment work of the radiation panel 131 can be further facilitated.

(8) Flexibility in Selection of Seat Material According to the present embodiment, the conditioned air blown from the air outlet 55 of the air conditioner 51 is led into the room R from the air outlet 115 . In other words, there is no need to intentionally introduce conditioned air into the room R through the cloth cover 141 .
For this reason, the fabric cover 141 is not required to have characteristics for passing conditioned air.
Basically, the fabric cover 141 is required to have air permeability to the extent that the air passing through the conditioned air flow path 151 is leaked to the room R side and a layer of dry air is generated on the front side of the surface fibers 141A. Only.
Therefore, according to the present embodiment, it is possible to widen the selection of materials for the sheet.

(9) Suppression of Sheet Deformation According to the present embodiment, the fabric cover 141 of the radiation panel 131 is arranged along the direction in which the conditioned air blown from the blower outlet 55 flows through the flow path 151 . Since the air flowing through the flow path 151 is discharged from the discharge port 115, the internal pressure inside the flow path 151 does not increase.
Therefore, when the radiant air conditioner 11 is operated, there is no air flow or increase in pressure that would warp the cloth cover 141 of the radiation panel 131, and deformation of the cloth cover 141 can be suppressed as much as possible.

(10) Thermal Efficiency The panel substrate 111 is made of a heat insulating material, and is in a state equivalent to providing the rear panel 112 and side walls 113 with heat insulating portions.
As a result, the heat of the conditioned air flowing through the flow path 151 is not lost to the panel base 111, and the cloth cover 141 can be efficiently heated or cooled. As a result, the radiant air conditioner 11 with excellent thermal efficiency can be obtained.
Moreover, since the panel base 111 itself is formed of a heat-insulating material, there is no need to separately prepare a heat-insulating material and attach it to the panel base 111, thereby reducing the component cost and manufacturing cost of the panel base 111, and increasing the manufacturing efficiency. can be facilitated.

(11) Features of Appearance (a) Appearance The air conditioner 51 is housed in a recess C1 provided on one surface of the room R (ceiling surface C), and the panel base 111 is joined to one surface of the room R. This makes it possible to make the radiant air conditioner 11 look thin and small in the room R.
Moreover, the radiant panel 131 also covers the air conditioner 51, and the open side of the bag-shaped cloth cover 141 is closed by the zipper 143, so that the radiant air conditioner 11 is arranged near the ceiling surface C from the outside. It appears to be in the form of only one radiant panel 131 . At this time, since only the cloth cover 141 made of the fiber material is exposed, the radiation panel 131 shows a gentle expression that is familiar to people's senses and sensitivities.
Therefore, it is possible to obtain the radiant air conditioner 11 with a refined appearance that does not become an obstacle or annoyance when installed in the room R.
(b) Use and Beauty Taking a step further, the reason why the radiant air conditioner 11 looks like only one radiant panel 131 arranged near the ceiling surface C is due to the following three factors. I notice.
・The radiation panel 131 is hollow due to the structure in which the frame 132 is covered with the fabric cover 141. ・The horizontal projection area of the radiation panel 131 is larger than the width of the rear panel 112. ・The horizontal projection area of the radiation panel 131 is 51 and rear panel 112. The structure of the radiation panel 131 and the size relationship of the horizontal projection area of each part are closely related to the above-mentioned "use" of enlarging the heat radiation area. In other words, the size relationship of the horizontal projection area that the radiation panel 131 is wider than the rear panel 112 contributes to expanding the heat radiation area of the radiation surface RS in the width direction. The size relationship of the horizontal projection area that the radiation panel 131 covers the air conditioner 51 contributes to expanding the heat radiation area of the radiation surface RS to the area overlapping the air conditioner 51 . Such expansion of the heat radiation area of the radiation surface RS depends on the structure of the radiation panel 131, which is originally hollow.
From the above observations, it can be seen that the aesthetic appearance of the radiant air conditioner 11 is "beauty" associated with "use".

4. Modifications Various modifications and changes are possible in practice.

(1) Installation location of radiant air conditioner For example, in the present embodiment, the radiant air conditioner 11 is installed on the ceiling surface C. It may be configured to be installed. In this case, if a depression is provided in the wall surface W and the air conditioner 51 is accommodated in this depression, it looks as if the radiation panel 131 is only installed on the wall surface W, as in the present embodiment. A radiant air conditioner 11 in flat form can be realized.

(2) State of installation of radiant air-conditioning device Also, an example is shown in which the ceiling surface C is a raised ceiling and the air conditioner 51 is housed in the depression C1, but this is not always essential, and the flat ceiling surface C or the wall surface W can be used. An air conditioner 51 may be installed. At this time, the air outlet 55 of the air conditioner 51 tends to separate from the ceiling surface C or the wall surface W, but by installing the radiation panel unit 101 floating from the ceiling surface C or the wall surface W, it becomes the entrance of the flow path 151. The inlet 114 can face the outlet 55 .
As a means for attaching the air conditioner 51 to the ceiling surface C, it is possible to employ various means other than the hanging bolts exemplified above. For example, various modifications such as a fastening structure using screws, a fastening structure using surface tape, and a press-fitting structure are allowed.

(3) Arrangement of Air Conditioner and Rear Panel In the present embodiment, the outlet 55 of the air conditioner 51 and the rear panel 112 of the panel base 111 are arranged side by side with a gap therebetween. In practice, the rear panel 112 may be attached to the ceiling surface C so as to be adjacent to the outlet 55 of the air conditioner 51 .
What is important at this time is that the inlet 114 of the panel base 111 communicates with the outlet 55 .
The term “communication” here means that the air-conditioned air blown out from the outlet 55 is guided to the inlet 114. As long as the outlet 55 and the inlet 114 are spaced apart from each other, , may be arranged on top of each other or may be arranged on top of each other. That is, the air conditioner 51 and the rear panel 112 may be arranged apart from each other, may be arranged in contact with each other, or may be arranged so as to overlap each other.

(4) Structure of Radiation Panel The radiation panel 131 is not limited to the structure in which the frame 132 is covered with the cloth cover 141. For example, the frame 132 is covered with Japanese paper, or it is assembled with a board having air permeability. It may be something like Radiation panels 131 made of various materials and structures are acceptable as long as they are hollow with a radiation surface RS having air permeability on one side and an opening O on the opposite side.
When adopting a structure in which the frame 132 is covered with the cloth cover 141 as in the radiation panel 131 of this embodiment, various modifications and changes are allowed for the structures, shapes, materials, etc. of the frame 132 and the cloth cover 141. be done. For example, the number and arrangement positions of the rod-shaped members 133 that constitute the frame 132 are not limited to those introduced in this embodiment, and various numbers and arrangements are possible.

(5) Radiation Panel Fixing Structure (a) Slider Attachment Position In the present embodiment, a configuration example in which the slider 137 is attached to the second frame 135 is exemplified. Implementation is not limited to such a configuration, and the slider 137 may be provided in a connection region between the first frame 134 and the second frame 135 . For example, it is possible to attach the slider 137 to the first frame 134 . Alternatively, although the hinge 136 is used as a member for connecting the first frame 134 and the second frame 135, a larger connecting member is used as such connecting member, and the slider 137 is attached to such a large connecting member. You may do so.
(b) Another fixing structure In this embodiment, a pair of sliders 137, a pair of connecting pins 138, and a pair of suction plates 139 are used to fix the radiation panel 131 to the air conditioner 51 and the panel base 111. However, various structures can be adopted for fixing the radiation panel 131 .
For example, depending on the weight of the radiation panel 131, a fixing structure using only magnets may be adopted.
(c) First Panel The structure for fixing the first panel 131A is not limited to the magnet MG, and various modifications such as a fastening structure using screws or bolts, a fastening structure using hook-and-loop tape, and a press-fitting structure are allowed.

(6) Form of Radiation Panel In the above-described embodiment, the radiation panel 131 has a flat plate shape, but various forms are permitted in practice.
For example, as shown in FIG. 31(a), the radiating panel 131 may have an arched shape with both sides hanging down when viewed from the front. At this time, the planar shape of the radiating panel 131 may be a rectangular shape as shown in FIG. 31(b) or an elliptical shape as shown in FIG. 31(c).
Also, the radiation panel 131 need not be in close contact with the ceiling surface C, and may be suspended from the ceiling surface C as shown in FIG.

(7) Side Walls In the above-described embodiment, the pair of side walls 113 are exemplified as rising from both side edges of the rear panel 112 . On the other hand, in practice, the sidewall 113 does not necessarily rise from the side edges, but may have a form in which it rises from a position closer to the center.
In addition, the walls realized as the pair of side walls 113 in this embodiment may have any form as long as they rise from the rear panel 112 in the form of an enclosure leaving the inlet 114 and the outlet 115. .
Furthermore, the pair of side walls 113 need not be integrated with the rear panel 112 as long as they are interposed between the rear panel 112 and the radiation panel 131 .

(8) Discharge Port In the above-described embodiment, an example in which the discharge port 115 is provided in the region facing the introduction port 114 is shown, but various modifications and changes are allowed in practice. For example, the outlet 115 may be provided in a part of the side wall 113, and in this case, the outlet 115 may be distributed at a plurality of locations.

(9) Variation of Sheet Chuck Position The position of the chuck 143 of the cloth cover 141 is not limited to the position shown in FIG. Various embodiments are allowed, such as a position near the edge, a position surrounding three sides as shown in FIG. 33(c), or a V-shape as shown in FIG. 33(d).

(10) Another Configuration Example of Radiant Air Conditioning Device FIG. 34 is a front view showing another configuration example of the radiant air conditioning device 11 .
In the embodiment shown in FIGS. 1 to 33 and its modification, the panel base 111 is provided with the side wall 113, thereby securing the space for the flow path 151 between the rear panel 112 and the radiation panel 131. . On the other hand, the radiant panel unit 101 of the radiant air conditioner 11 shown in FIG.
Therefore, the radiation panel 131 is provided with a three-dimensional frame 132 rather than a planar one, thereby creating a space for the flow path 151 between the radiation panel 131 and the rear panel 112 . More specifically, the frame body 132 is curved in a curved shape when viewed from the front and rear sides, and both end portions thereof are connected and fixed to the rear panel 112 . The fabric cover 141 is attached to the frame 132 so as to cover the room R side. The cloth cover 141 is fixed to the frame 132 by, for example, hooking both sides of the cloth cover 141 to both sides of the frame 132 . The cloth cover 141 is fixed to the frame 132 in a stretched state.
Due to such a structure, the panel substrate 111 does not have the side walls 113 and is mainly composed of the rear panel 112 .
The radiant panel unit 101 configured in this manner has an inlet 114 formed on the rear side, an outlet 115 formed on the front side, and a light source 114 from the inlet 114 between the rear panel 112 of the panel base 111 and the radiant panel 131 . A flow path 151 for conditioned air leading to the outlet 115 is formed.
Therefore, the same effects as those of the embodiment shown in FIGS. 1 to 33 are obtained.
