BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0010]
FIG. 1 shows an embodiment of a built-in type air conditioner according to the present invention. Reference numeral 30 denotes a built-in type air conditioner. The built-in type air conditioner 30 is suspended from a ceiling space 34 between a ceiling 32 and a ceiling plate 33 of a building 31, and is provided with a unit body 35 and a suction unit. It has a duct 36, an outlet duct 50, and an operation control electrical box 37.
[0011]
The unit main body 35 is configured such that a top plate 39 is fixed to an upper edge portion of four side plates 38 provided in a rectangular frame shape facing each other and a bottom plate 46 is fixed to a part of a lower edge portion. . A heat insulating material is attached to the inner and outer surfaces of the side plate 38, the top plate 39, and the bottom plate 46. A hanging bracket 41 is fixed to the side plate 38 of the unit main body 35, and the hanging bracket 41 is fixed to a hanging bolt 42 hanging down from a ceiling 32 of the building 31, so that the built-in type air conditioner 30 is mounted on the building 31. The ceiling 31 can be suspended from the ceiling 32.
[0012]
As shown in FIG. 2, the indoor heat exchanger 1, the fan 2, and the fan motor 3 are housed inside the unit main body 35. 4 is a partition plate. A refrigerant pipe (liquid pipe) connected to the refrigerant pipe connection port 43 and a refrigerant pipe (gas pipe) connected to the refrigerant pipe connection port 44 are connected to the indoor heat exchanger 1. , Are connected to an outdoor unit (not shown). The indoor heat exchanger 1 cools or heats the air sucked into the unit main body 35.
[0013]
The suction duct 36 is supported by a suspension bolt 40, and usually, a plurality of the suction ducts 36 extend from the unit main body 35. One end of the suction duct 36 is fitted in a filter chamber 47 integrally provided on one side plate 38 of the unit main body 35, and a suction grill 48 is attached to the other end. The suction grill 48 is installed at an appropriate position on the ceiling plate 33. The outlet duct 50 is supported by a suspension bolt 40, similarly to the above-described suction duct 36, and has one end connected to the outlet grill 51 and the other end connected to the outlet 49 of the unit body 35. When the fan in the unit main body 35 is driven, air is sucked into the unit main body 35 through the suction grill 48 and the suction duct 36, and the air that has been heat-exchanged by the indoor heat exchanger 1 flows through the blow-out duct 50. After that, the air is blown into the room from the blowout grill 51.
[0014]
As shown in FIG. 1, the electrical box 37 is attached to a side plate 38A of the unit body 35 where the suction duct 36 and the outlet duct 50 are not provided. The electrical component box 37 has a substantially rectangular parallelepiped shape, and is provided with a control board, a terminal plate, and the like (not shown) therein. Wiring from a fan motor, a drain pump, a float switch, an electronic control valve, various sensors, and the like installed in the unit main body 35 are connected to the control board or the terminal plate.
[0015]
In this built-in type air conditioner 30, as shown in FIG. 2, a maintenance opening 5 is opened in a ceiling plate 33 near the electrical box 37, and a lid 5A (FIG. 1) is installed here. After that, the worker enters the space above the ceiling, and, for example, the electrical box 37 is maintained.
[0016]
3 and 4 are plan views of a business hotel and the like. In FIG. 3, this building is provided with symmetrical rooms A and B. In each of the rooms A and B, a toilet, a bath, a bed, and the like are arranged. In each of the rooms A and B, the space indicated by 100 indicates the space above the ceiling. The unit main body 35 is arranged in the back of the ceiling 100 of each of the rooms A and B. As shown in FIG. 3, when the wall 11 is opposed to the electrical box 37, maintenance of the electrical box 37 is impossible at this site even if the wall 11 enters the ceiling from the maintenance opening 5.
[0017]
At this site, as shown in FIG. 4, the mounting position of the electrical component box 37 is changed to a position facing the maintenance opening 5.
[0018]
In order to realize this, in the present embodiment, as shown in FIG. 2, the opening side portions 100A and 100B are provided on the adjacent side surface 38A and the rear surface 38B of the unit main body 35, respectively. The electronic component box 37 is configured to be selectively attached to any of the scheduled parts 100A and 100B.
[0019]
The distance between the electrical box 37 and the fan motor 3 is set to be substantially equal even if the electrical box 37 is attached to either of the planned openings 100A and 100B. Even if the electrical box 37 is attached to any of the opening portions 100A, 100B, the wiring to be connected to the electrical box 37, that is, the fan motor 3, the drain pump, The wiring from the float switch, the electronic control valve, various sensors, and the like is set so as to reach any one of the electrical boxes 37.
[0020]
Here, in the example of FIG. 2, the electrical box 37 is attached to the scheduled opening portion 100 </ b> A so as to correspond to the position of the maintenance opening 5, but at the site shown in FIG. Then, the mounting position of the electrical box 37 is changed, and the electrical box 37 is mounted on the scheduled opening portion 100B of the rear surface 38B.
[0021]
A filter chamber 47 is provided on the back surface 38B, but the electrical box 37 is mounted at a position avoiding the suction port, and the electrical box 37 does not become a suction resistor. In addition, when the electrical component box 37 is mounted at this position, the electrical component box 37 is disposed so as to surround the fan motor 3, so that the electromagnetic noise of the motor does not leak to the outside, and a sound insulation effect can be obtained. In addition, for opening the opening to which the electrical box 37 is not attached, that is, in the example of FIG. 2, the opening is to be closed at the opening 100B, and at the site shown in FIG. A lid (not shown) is fixed using screws or the like.
[0022]
The electrical box 37 is usually attached to the scheduled opening portion 100A at the time of shipment from the factory. At the installation site, the mounting position of the electrical box 37 is changed as necessary, and the electrical box 37 is attached to the scheduled opening portion 100B.
[0023]
In the present embodiment, the adjacent side surfaces 38A and the rear surface 38B of the unit main body 35 are provided with planned openings 100A and 100B, respectively, and the electrical box 37 can be selectively attached to any of the planned openings 100A and 100B. Therefore, the mounting position of the electrical box 37 can be changed according to the situation at the site, and a sufficient maintenance space for the electrical box can be secured.
[0024]
Regardless of the position where the electrical box 37 is attached, the distance between the electrical box 37 and the fan motor 3 is substantially equal, so that there is no difference in the heat dissipation of the fan motor 3. In addition, since the wiring to be connected to the electrical box 37 is set so as to reliably reach the electrical box 37 attached to any of the planned openings 100A and 100B, the mounting position of the electrical box 37 is set. Does not make wiring difficult. It is important that the length of the wiring not only reaches the electrical component box 37 attached to any of the planned openings 100A and 100B, but also does not survive too much.
[0025]
In the example of FIG. 2, even if the electrical box 37 is attached to any of the opening portions 100A and 100B, the distance between the electrical box 37 and the fan motor 3 becomes substantially equal, and furthermore, the electrical box 37 is connected to the electrical box 37. Although the wiring to be set is set so as to reach any of the electrical boxes 37, if this condition is not satisfied, for example, as shown in FIG. It is clear that the electrical box 37 may be attached to the metal fitting 15 so that the distance between the electrical box 37 and the fan motor 3 may be equal.
[0026]
As described above, the present invention has been described based on one embodiment, but the present invention is not limited to this.
[0027]
【The invention's effect】
ADVANTAGE OF THE INVENTION In this invention, the maintenance space of an electrical component box can be fully ensured regardless of the situation of the installation site.
