  In the conventional ceiling-suspended air conditioner, the electrical component box is disposed between the blower and the rear panel, and the electrical component box can be accessed by removing the grill and the filter. However, when maintaining the electrical components in the electrical box, there is a problem that it is necessary to remove the electrical box after removing the grille and filter because the space between the blower and the back panel is very narrow. .

  The present invention has been made to solve the above-described problems. The first object is to maintain the cover of the electrical component box without removing the entire electrical component box when maintaining the electrical component. It is possible to obtain a ceiling-suspended air conditioner that can maintain electrical components in the electrical component box by simply removing it.

  In addition, the second purpose is to move the position where the separator and the lower surface are in contact further forward, so that the electrical component box can be arranged below the blower outlet without hindering the compactness of the housing. Thus, a ceiling-suspended air conditioner capable of expanding the suction port and reducing suction pressure loss as an effect thereof is obtained.

  The third object is to arrange the electrical box in the center, not the back of the housing, so that a suction port can be set on the back of the housing, and the suction pressure loss can be reduced as an effect. A ceiling-suspended air conditioner is obtained.

  In the ceiling-suspended air conditioner according to the present invention, a rectangular parallelepiped casing that is installed to be suspended from the ceiling has an air inlet and an outlet, and a separator that separates and separates the suction side and the outlet side in the casing. An air conditioner that is installed and includes a filter, a blower, a heat exchanger, and the like in the air passage, and is disposed obliquely so that the lower part of the separator projects forward from the blower outlet, and an electrical component box Is fixed to the separator below the blower outlet.

  In the ceiling-suspended air conditioner according to the present invention, a rectangular parallelepiped casing that is installed to be suspended from the ceiling has an air inlet and an outlet, and a separator that separates and separates the suction side and the outlet side in the casing. An air conditioner that is installed and includes a filter, a blower, a heat exchanger, and the like in the air passage, and is disposed obliquely so that the lower part of the separator projects forward from the blower outlet, and an electrical component box Since it is arranged to be fixed to the separator below the blower outlet, when maintaining the electrical parts in the electrical box, it is not necessary to remove the electrical box as a whole. It has the effect that the electrical components in the box can be maintained.

Embodiment 1 FIG.
A cross-sectional view of a ceiling-suspended air conditioner according to Embodiment 1 of the present invention shown in FIG. 1 will be described below. In the figure, a ceiling-suspended air conditioner installed on a ceiling 1 has a rectangular parallelepiped casing 2 that forms an air passage 5 having an air inlet 3 on the lower surface and an air outlet 4 on the front surface. A separator 6 for separating and separating the suction side 5a and the blowing side 5b is installed in the passage 5, and a filter 7, a blower 8 and an electrical component box 9 are arranged on the suction port 3 side in the air passage 5, A heat exchanger 10 is disposed on the outlet 4 side. The separator 6 is disposed obliquely in a direction in which a lower portion projects forward in the housing 2, and a blowout port 8 a of the blower 8 is mounted through the separator 6, so that the separator 6 and the housing 2 The position in contact with the lower surface is in contact with the front side of the blower outlet, and the suction port 3 is expanded forward of the conventional ceiling-suspended air conditioner. The electrical component box 9 has an electrical component box cover 9a, and is arranged to be fixed to the separator 6 below the blower outlet 8a of the blower 8.

  Next, the operation of the first embodiment will be described. When the blower 7 is driven, the indoor air sucked from the suction port 3 and entering the inside of the housing 2 is dust-removed by the filter 7 as indicated by an arrow in the air passage 5, and then the air sent from the blower 8 is The temperature is adjusted as heat exchange air by being blown from the outlet 8a of the blower 8 to the heat exchanger 10, and is sent out as conditioned air from the outlet 4 in the housing 2.

  As described above, since the separator 6 is disposed obliquely, the area of the suction port 3 can be increased as compared with the case where the separator 6 is disposed vertically as in the prior art. This contributes to an increase in the air volume at the same rotation speed. That is, when viewed with the same air volume, there is an effect that the rotational speed is reduced and noise is reduced.

  Further, since the lower part of the space on the suction side 5a can be expanded forward, the electrical component box 9 can be placed below the outlet 8a of the blower 8 without increasing the height and depth of the casing 2, that is, without hindering compactness. Can be arranged. As an effect of arranging the electrical component box 9 in the center instead of the back surface of the housing 2, it is possible to maintain the electrical component box cover without removing the entire electrical component box 9 when maintaining the electrical components in the electrical component box 9. The electrical components in the electrical component box 9 can be maintained simply by removing 9a.

  FIG. 2 is a cross-sectional view of another embodiment of the present invention. In the figure, the casing 2 of the ceiling-suspended air conditioner forms an air passage 5 having an air inlet 3 and an outlet 4 and is separated into a suction side 5a and an outlet side 5b. A separator 6 for partitioning is installed, and the separator 6 contacts the lower surface of the casing 2 and the inclined surface 6b for mounting the vertical fixing portion 6a and the electrical component box 9 to fix the outlet 8a of the blower 8. It consists of a lower end curved portion 6c.

  Thus, in other embodiments, even if the separator 6 is formed as shown in FIG. 2 with the aim of improving the assemblability, there is no change in these effects.

  In the first embodiment described above, the suction port 3 is provided only on the lower surface of the housing 2 as in the past, but a gap is provided between the wall surface 11 and the back surface 2a of the housing 2 at another installation location. In the situation where this is permitted, an explanation will be given of a case where a suction port is provided on the back as an option.

  FIG. 3 is a cross-sectional view of another embodiment of the present invention. In FIG. 3, the casing 2 of the ceiling-suspended air conditioner is formed with an air passage 5 having an air inlet 3 and an outlet 4, and the two air passages 5 in the casing are provided with an inlet side 5 a and an outlet side 5 b. A separator 6 for separating and partitioning is installed, and a filter 7, a blower 8 and an electrical component box 9 are provided on the suction port 3 side in the air passage 5, and a heat exchanger 10 is provided on the blowout port 4 side. The separator 6 is arranged so that the lower side in the casing 2 is inclined forward in the forward direction so that the contact position between the separator 6 and the lower surface of the casing 2 is in contact with the front. It is expanding forward. Further, a rear suction port 2b and a rear filter 12 are provided on the rear surface 2a of the housing 2.

  As described above, since it is possible to suck air from the suction port on the rear surface of the housing in addition to the suction port on the lower surface of the housing as in the past, the total sum of the suction port areas should be further expanded than in the first embodiment. As an effect, the suction pressure loss can be reduced and the total air volume can be increased.
