Description

  The present invention relates to an indoor air-conditioning structure, and more particularly to an indoor air-conditioning structure in which an indoor unit of an air conditioner is attached to a joint angle portion between a side wall portion and a ceiling portion.

  As a method of cooling and heating a room, a method of air-conditioning a room using an air conditioner (air conditioner) having a function of blowing cold air or hot air is generally employed. Air conditioning by an air conditioner is usually performed with the indoor unit attached to the side wall of the room, and such an air conditioning structure with a wall-mounted type air conditioner has the indoor unit protruding from the wall surface. Because it will be exposed, it is easy to damage the beauty of the room. For this reason, an air conditioning structure in which the indoor unit is built in the ceiling or side wall is used for the purpose of improving the aesthetics of the room. However, in the type in which the indoor unit is built in the ceiling, Since it is difficult to create an upward air flow, an unpleasant air flow sensation is likely to occur, and in the type in which the indoor unit is built in the side wall part, it is difficult to generate a downward air flow during heating, and it is difficult to warm up to the feet.

  On the other hand, when air conditioning indoors using an air conditioner, air currents caused by cold air or hot air may cause discomfort to the residents. An air conditioning system with improved comfort has also been developed (see, for example, Patent Document 1). In the air conditioning system of Patent Document 1, a double ceiling composed of a lower ceiling body and an upper ceiling body is provided in a ceiling portion of the room, and cold air and hot air are blown out from the indoor unit of the air conditioner into the double ceiling. The double ceiling is cooled or warmed, and indoor air conditioning is performed by radiant heat from the lower ceiling.

  Further, in the air conditioning system of Patent Document 1, the lower ceiling body is formed of a material having moisture permeability and air permeability such as Japanese paper or polyester sheet, so that a part of the cold air and the warm air from the indoor unit is lowered to the lower ceiling body. In addition to cooling and heating by radiant heat, cooling and heating by a weak airflow that has passed through the lower ceiling body can be performed. Furthermore, in the air conditioning system of Patent Document 1, an accommodation recess is formed by recessing the upper ceiling in a concave shape at the joint angle portion between the side wall where the indoor unit is installed and the upper ceiling, and this accommodation accommodation recess. The upper part of the indoor unit is housed in the lower ceiling so that the lower ceiling can be placed as close as possible to the upper ceiling, and the space in the living room is not narrowed up and down.

It is installed in a state of projecting with a depth of, for example, about 1000 mm toward the side wall surface 11a of the other short side portion without causing a gap with the surface 11b.

  As a result, the blower plate 16 covers the indoor unit 15 and the upper housing recess 17 from below and has a height position close to the lower surface portion 15c of the indoor unit 15 such as about 50 mm from the lower surface portion 15c of the indoor unit 15. Arranged at spaced height positions. Further, the blower plate 16 functions as a folding ceiling disposed below the ceiling portion 13 and improves the design of the living room portion 11. It is preferable that the blower plate 16 is detachably attached so that the maintenance of the indoor unit 15 can be easily performed, for example. A portion of the blower plate 16 directly below the indoor unit 15 is provided with a blindfolding plate portion 19 through which warm air from the indoor unit 15 is mainly sent out directly to the living room space below the blower plate 16.

  As the blindfold plate portion 19, for example, a structure having a known gallery structure can be adopted as a structure having a large number of vent openings that can be opened and closed. The blindfolding plate portion 19 having a louver structure is configured to open and close the spaces between a large number of rotatable blades by rotating the blades, thereby blocking ventilation and the ventilation. The state to be performed can be switched as appropriate. The blindfold plate portion 19 is attached so as to be fitted into the blower plate 16 made of a panel member, and is integrally fixed to the blower plate 16. The blindfold plate portion 19 is provided so as to occupy a horizontally long rectangular region having a lateral width of, for example, about 800 mm and a depth of about 300 mm in the blower plate 16, and is directly below the blowout port of the indoor unit 15. The side edge portion on the side wall surface 11a side is preferably spaced apart from the side wall surface 11a of one short side portion of the living room portion 11 by about 200 mm, for example.

  And according to the indoor air-conditioning structure 10 of this embodiment provided with the above-mentioned structure, while maintaining the function of covering the indoor unit 15 of the air conditioner and the function of preventing the space of the living room portion 11 from being narrowed up and down, the cooling and heating are performed. It is possible to effectively prevent the rise of the effect from being delayed, it is difficult to warm up to the feet during heating, and the load on the air conditioner is increased.

  That is, according to this embodiment, the blower plate 16 can cover the air conditioner indoor unit 15 from below without exposing it, and the blower plate 16 can be installed as a folded ceiling. It becomes possible to improve the design nature of living room part 11 effectively. Moreover, although the indoor unit 15 is attached to the side wall part 12 in the wall-hanging form, it is installed in a state in which the upper part is housed in the upper accommodating recess 17, and only the lower part of the indoor unit 15 having the blowout opening is installed on the ceiling. Since it is arrange | positioned below the part 13, the ventilation board 16 is arrange | positioned under the ceiling part 13 so that the space | interval between the ceiling parts 13 may become a small space | interval about the half of the height of the indoor unit 15. This makes it possible to secure a living space of a considerable height below the blower plate 16 so that the space of the living room portion 11 does not become narrower in the vertical direction. It becomes possible for a person not to feel a feeling of pressure by the blower plate 16.

  Further, according to the present embodiment, for example, at the time of cooling, the blown cold air is blown out by the blower plate 16 by blowing the cold air from the blowout port of the indoor unit 15 in a state where the blindfolded plate portion 19 of the blower plate 16 is closed. Passing the gap between the ceiling 13 and the blower plate 16 while guiding it to flow along the ceiling 13, and further flowing along the lower surface of the ceiling 13, it is circulated in the lower living room 11. Therefore, it is possible to prevent the rise of the cooling effect from being delayed by the blowing of the cold air while avoiding the direct blowing of the cold air to the resident.

  Furthermore, since the cooling plate blown from the blower outlet passes through the space between the ceiling portion 13 and the blower plate 16, the blower plate 16 is cooled, so that the cooling effect by the radiant cooling heat from the blower plate 16 can be obtained. The cooling air sent out along the lower surface of the ceiling portion 13 by the blower plate 16 flows along the lower surface of the ceiling portion 13 at a portion ahead of the blower plate 16 to cool the ceiling portion 13. Therefore, it is possible to obtain a cooling effect by radiant cooling from the lower surface of the cooled ceiling portion 13.

  Moreover, after the cold wind that has flowed along the lower surface of the ceiling portion 13 circulates in the lower living room portion 11 and the temperature is relaxed or rises, the interval portion between the ceiling portion 13 and the blower plate 16 is again formed. Since the air passes through and is returned to the indoor unit 15, it is possible to effectively avoid an increase in the load on the air conditioner due to the temperature of the air returned to the indoor unit 15 being lowered.

  On the other hand, for example, at the time of heating, the hot air blown out from the outlet of the indoor unit 15 with the blindfold 19 of the blower plate 16 opened, the blown warm air is a side surface to which the indoor unit 15 is attached. After flowing downward along the part 15b, it is made to circulate in the living room part 11, so that the rise of the heating effect is slowed by the blowing of warm air while avoiding direct blowing of cold air to the occupant. This makes it possible to prevent the occupant from getting lost and also allows the occupant's feet to be warmed quickly and easily.

  Further, by adjusting the opening rate of the blindfold plate portion 19 as appropriate, or by closing the blindfold plate portion 19 as appropriate and sending warm air along the blower plate 16, the heating effect due to the radiant heat of the blower plate 16, and the ceiling The heating effect by the radiant heat of the part 13 can also be obtained.

  Furthermore, after the warm air blown out from the indoor unit 15 is circulated through the living room 11 and the temperature is reduced or lowered, the hot air passes through the space between the ceiling 13 and the blower plate 16 and passes through the indoor unit. Therefore, it is possible to effectively prevent the temperature of the air returned to the indoor unit 15 from becoming high and increasing the load on the air conditioner.

  Therefore, according to the indoor air-conditioning structure 10 of the present embodiment, the wall-mounted type air conditioner indoor unit 15 is folded down by the blower plate 16 without impairing the normal function due to air blowing and without damaging the aesthetic appearance. In addition to being able to be built in the ceiling, it is possible to realize an air conditioning system capable of switching between cooling and heating by radiation and cooling and heating by convection.

  Further, according to the present embodiment, for example, a lighting fixture is attached to the back side of the blower plate 16 so as to illuminate the ceiling portion 13, so that the folding ceiling by the blower plate 16 is used as a structural part for obtaining indirect illumination. Thus, it is possible to further improve the beauty of the living room 11.

  Furthermore, according to this embodiment, as shown in FIG. 4, cold air or hot air sent along the air blowing plate 13 from the outlet of the indoor unit 15 at the space between the ceiling portion 13 and the air blowing plate 16. It is also possible to provide the wind direction guide plate 21 for guiding the direction in one or a plurality of places. The wind direction guide plate 21 is preferably provided with a rotatable structure so that the guiding direction can be appropriately adjusted. By providing the wind direction guide plate 21, cold air or hot air blown from the blowout port of the indoor unit 15 is sent out toward a predetermined area of the living room portion 11 or dispersed throughout the living room portion 11. It can be sent out.
