Description

  The present invention relates to a ceiling-embedded air conditioner including an illumination light source.

In general, a ceiling-embedded air conditioner in which a unit body is embedded in a ceiling and a decorative panel is exposed on the ceiling surface of a ceiling board is known (see Patent Document 1). In this type, the decorative panel has a suction port substantially in the center, and has a blow-out port outside the suction port, and the blow-out ports are arranged in four or two directions. In recent years, it has been proposed that a unified illumination line is provided as an interior of a building, for example, on a ceiling surface, and an air conditioner with a ceiling embedded is arranged on the illumination line so as not to get in the way.
JP-A-5-187649

  However, in the conventional one, the shape of the decorative panel does not match the lighting line, and there may be a sense of incongruity in the interior design.

  In addition, when a ceiling-embedded air conditioner is installed in the center of the ceiling of a living room or the like, the illumination light source must be installed in a position opposite to this, and thus, If the necessary brightness cannot be obtained or if the illumination light source is placed in the center of the room, the ceiling-embedded air conditioner must be placed in a location that avoids this, thereby obtaining the required air conditioning. In addition to being restricted by interior design, such as being unable to do so, there is a risk of sacrificing brightness and air conditioning. In general lighting, it is important to ensure brightness according to the design (hereinafter referred to as necessary brightness). To that end, lighting devices of a certain size may have to be arranged. In this case, the installation space of the ceiling-embedded air conditioner may be limited.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a ceiling-embedded air conditioner that is integral with an illumination light source and that can ensure the necessary brightness.

The present invention provides a ceiling-embedded air conditioner in which a unit main body is embedded in a ceiling and a decorative panel is exposed on a ceiling surface of a ceiling board. The decorative panel has a suction port at a substantially central position. There is a blowout port on the outside, a face material facing the room outside the blowout port, and a slant that is connected to the face material and goes outward of the blowout port as it goes vertically downward. and the hollow portion formed by the side face member, the illumination light source within the hollow portion is arranged, as well as illuminating the room directly through the facing material by the illumination light source, through the side member by said illumination light source The room is indirectly illuminated by illuminating the ceiling.

In this case, before Symbol blowing opening may be arranged in four or two directions.

  According to the present invention, since the decorative panel is formed in a hollow shape and the illumination light source is arranged in the hollow, an air conditioner that is integral with the illumination light source and can secure the necessary brightness is provided. Moreover, if it is formed in a hollow shape on the outside of the outlet, and an illumination part having an illumination light source is provided in the hollow, the thickness and width of the illumination part can be appropriately designed, as required. An air conditioner integrated with an illumination light source is provided.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
1 is a sectional view of a four-way cassette type air conditioner according to the present embodiment, FIG. 2 is a perspective view, FIG. 3 is a front view, and FIG. 4 is a rear view. In each figure, 1 shows an air conditioner. The air conditioner 1 includes a unit main body 2A including a sheet metal casing 2 housed inside the ceiling, and a decorative panel 7 disposed on the lower surface of the casing 2. The decorative panel 7 is attached to the lower surface of the housing 2 in close contact with the ceiling surface 6A of the ceiling board 6 so as to close the opening 5 of the ceiling. The decorative panel 7 has a suction port 3 substantially in the center, and is provided with a makeup grill 8 at the inlet of the suction port 3, and the makeup grill 8 supports an air cleaning filter 25. ing. The decorative panel 7 has a blowout port 4 that is formed along the four sides outside the suction port 3 and blows wind in four directions. A flap for changing the wind direction is provided at the blowout port. 9 is arranged.

  A centrifugal blower 27 includes a turbo fan 12 and a motor 14 attached to the top plate 13. A drain pan 16 is disposed so as to cover the lower surface of the heat exchanger 21, and is a drain pan formed of foamed polystyrene in an angular ring shape. Reference numeral 21 denotes a plate fin type heat exchanger arranged in an annular shape on the discharge side of the turbo fan 12 so as to surround the fan. Reference numeral 23 denotes a blow-out space for guiding the air heat-exchanged by the heat exchanger 21 to the blow-out port 4, and 24 denotes a suspension bolt for suspending the casing 2 from the ceiling beam with a suspension tool.

  In this air conditioner 1, refrigerant is supplied to the heat exchanger 21 from an outdoor unit (not shown), and indoor air is circulated by the centrifugal blower 27 through the suction port 3. The air is heated or cooled by the refrigerant, the wind direction is controlled by the flap 9, and the wind is blown out in four directions from the outlet 4.

  In this structure, as shown in FIG. 1, it comprises the illumination part 11 over four sides in the outward of the blower outlet 4 of the decorative panel 7. In FIG. The illuminating unit 11 has a hollow portion 11C, and at least the indoor side surface material 11A and the four inclined side surface materials 11B are formed of a light transmissive member, for example, a milky white shade member. .

  The illumination unit 11 accommodates an illumination light source 13 such as a circle-shaped fluorescent tube. The illumination unit 11 has a thickness H necessary for housing the illumination light source 13 and is formed with a predetermined width W so that the overall brightness of the room can be sufficiently maintained. ing. In the illumination unit 11, illumination through the face material 11A is direct illumination, and illumination through the side material 11B is indirect illumination.

  This illumination part 11 is integrally formed outside the blowout port 4 of the decorative panel 7 so as to surround the blowout ports 4 on the four sides. In addition, it is completely integrated with the decorative panel 7.

  In general, if the air conditioner 1 is a room having a size of, for example, about 20 tatami mats, the air conditioner 1 is installed at an ideal position approximately in the center of the indoor ceiling. In this case, it is desirable that the lighting device is also installed at an ideal position approximately in the center of the indoor ceiling. In this configuration, by installing the air conditioner 1 at an ideal position substantially in the center of the living room ceiling in a living room or the like, the illumination light source can be simultaneously attached to the ideal position. Therefore, necessary brightness in the living room and necessary air conditioning can be obtained at the same time.

  The necessary brightness depends on the light source. For this purpose, a small and thin object such as a high-intensity LED or other slim tube is suitable other than the circular fluorescent tube. In this structure, the illumination part 11 of thickness H and width W is provided over the four sides outside the outlet 4 of the decorative panel 7, and if the size of the light source is determined, the thickness of the illumination part 11 is accordingly changed. What is necessary is just to change H and the width W suitably, and required brightness can be obtained easily with a simple structure.

  In this configuration, since the lighting function having the same brightness as that of a general lighting fixture is integrated with the decorative panel 7, the layout of the air conditioner and the ceiling lighting is simplified, and the ceiling surface can be cleaned. In addition, the ceiling layout design can be advanced at the same time, and the construction period can be shortened and the construction cost can be reduced. Further, for example, when a human sensor is installed and the air conditioner and the ceiling lighting are simultaneously controlled, the systemization is simplified.

  In this structure, since the illumination part 11 was provided in the outward of the blower outlet 4, for example, the makeup | decoration grill 8 etc. inside the illumination part 11 can be set as the structure similar to the past. The decorative grill 8 is attached and detached during cleaning maintenance of the filter 25, but the decorative grill 8 does not have an illumination function. Accordingly, the decorative grill 8 has no connection such as electric wiring and can be attached and detached very easily. In addition, by providing the illumination unit 11 outside the blowout port 4, the size of the suction port 3 in the substantially central portion can be made larger as usual. Further, since the illumination unit 11 is greatly projected over the width W to the outside of the outlet 4, even if the installation of the unit main body 2A is slightly shifted to the left and right in the drawing, Since this illumination part 11 completely closes the ceiling opening 5, the installation of the unit main body 2A may be somewhat rough and easy to install.

  Further, as shown in FIG. 1, the indoor side surface of the illumination unit 11 and the indoor side surface of the decorative grill 8 are configured to be substantially flush with each other. An aesthetic appearance similar to that of a decorative panel can be obtained.

Further, in the above-described ceiling-embedded air conditioner 1, since the casing 2 is almost square, when one commonly used simple ceiling panel (ziptone) is removed, the size fits there and is installed. Can be improved.
In this case, the main body is about 850 mm square, and the decorative panel 7 may be formed to be about 1150 mm square, for example, depending on the size of the illumination unit 11.

  As mentioned above, although this invention was demonstrated based on one Embodiment, it is clear that this invention is not limited to this. For example, although the four-way cassette type has been described in the above configuration, the present invention is not limited to this. Even in the case of two directions or one direction, the decorative panel itself may be formed in a hollow shape, and the illumination light source may be disposed in the hollow.

It is sectional drawing which shows one Embodiment of this invention. It is a perspective view similarly. It is also a front view. It is a back view similarly.
