[Structure] An L-shaped through hole is provided on the left and right side surfaces of a blower base that supports the blower, and a horizontal hole at the lower end of this through hole is engaged with a screw for fixing the blower base to the frame body. [Effect] Even if the screw is loosened during maintenance or inspection of the blower, the blower can be prevented from dropping suddenly and work safety can be obtained.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air conditioner, particularly to a ceiling-mounted air conditioner.

[0002]

[Prior Art]

 Generally, when installing a ceiling-mounted air conditioner on the ceiling or above the ceiling, safety is important because it can be easily attached and detached. FIG. 4 is a configuration diagram of this type of ceiling-mounted air conditioner, in which 1 is a frame body of the air conditioner, 2 is a heat exchanger, 3 and 4 are cold and hot water piping ports of the heat exchanger 2, 5 is an air discharge grille, 6 is a drain plate of the heat exchanger, 7 is a drain port of the drain plate 6, 8 is a filter for filtering air sucked from a suction grill (not shown), and 9 is a heat exchanger 2. A blower for blowing air.

FIG. 5 shows a mounting structure of the blower 9, 10 is a blower base of the blower 9, 10a is a long through hole provided on a side surface of the blower base 10, and 11 is attached to the frame main body 1. With the guide plate, the blower stand 10 slides up and down along the guide plate 11.

FIG. 6 shows a fixing structure of the blower base 10. The screw 12 inserted from the outside of the frame body 1 is screwed and fixed to the nut 13 through the through hole 10 a of the blower base 10.

Next, the operation will be described. The air that has passed through the filter 8 is forcibly blown to the heat exchanger 2 by the blower 9. The blown air is heat-exchanged by the heat exchanger 2 and blown out from the discharge grill 5. The blower 9 is maintained and inspected in a state where the screw 12 is loosened and the blower base 10 is slid downward (see FIG. 5).

[0006]

[Problems to be solved by the device]

 Since the conventional blower mounting structure is as described above, loosening the screw 12 from the installed state of the blower 9 causes the blower base 10 together with the blower 9 to slide on the guide plate 11 and drop suddenly, which may cause an unexpected accident. There was a problem.

The present invention has been made to eliminate the above problems, and an air conditioner that does not cause a sudden drop of the blower even if the screw is loosened during maintenance and inspection of the blower. The purpose is to get.

[0008]

[Means for Solving the Problems]

 An air conditioner according to the present invention includes a heat exchanger in a frame body of the air conditioner, a blower for blowing air to the heat exchanger, and a drain tray below the heat exchanger, and a blower supporting the blower. In an air conditioner in which a stand is screwed to the frame body so that it can be moved up and down, an L-shaped through hole is provided on the side surface of the blower, and the horizontal hole at the lower end of this through hole is located on the screw to move the blower. It is characterized by being installed and fixed.

[0009]

[Action]

 In this invention, the screw that attaches the blower to the frame body is located in the horizontal hole of the L-shaped through hole of the blower base, so even if the screw is loosened during maintenance or inspection of the blower, The horizontal hole does not get caught and the blower does not fall by its own weight. When lowering the blower, it can be done by moving the through hole with respect to the screw from the horizontal hole to the vertical hole.

[0010]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of an air conditioner according to the present invention. Reference numerals 1 to 10 are the same as those of the conventional air conditioner described with reference to FIG. .. Reference numeral 14 is a guide plate of the blower stand 10, and is fixed to the left and right side surfaces of the frame body 1 in a state where the lower part of the other guide plate 14a is inclined outward and the space between the guide plates 14 and 14a is widened. Reference numeral 15 is an L-shaped through hole formed on the side surface of the blower stand 10. The vertical hole 15a of the through hole 15 is formed long along the blower stand 10, and the horizontal hole 15b is short at the lower end of the vertical hole 15a. So formed.

When the blower 9 is housed in the frame body 1, the blower base 10 fixed by the frame body 1 to the screw 12 is such that the horizontal hole 15 b of the through hole 15 is located at the screw 12. There is.

Next, the attachment / detachment operation of the blower stand 10 will be described with reference to FIGS. 2 and 3.

When removing the blower base 10 from the frame body 1, first, from the state shown in FIG. 3, first loosen the screw 12 and move the blower base 10 laterally to the inclined guide plate 14a side. The vertical holes 15a of 15 are located, and then the blower base 10 is pulled down to move the vertical holes 15a along the screws 12 as shown in FIG. 2, so that the blower can be removed together with the blower base 10.

When the blower stand 10 is housed in the frame body 1, if the blower stand 10 is tilted and pushed up along the inner plate 14a, the vertical hole 15a moves along the screw 12 as shown in FIG. , When the lower end of the vertical hole 15a reaches the screw 12, the horizontal hole 15b is engaged with the screw 12 as shown in FIG. 3, and the screw 12 is tightened, so that the blower 9 is attached to the frame body 1 together with the blower stand 10. It is stored.

[0015]

[Effect of the device]

 As described above, according to the present invention, an L-shaped through hole is provided in the blower base, and the horizontal hole at the lower end of the through hole is positioned on the screw for fixing the blower base to the frame body. For example, even if the screw is loosened for maintenance and inspection of the blower, the horizontal hole of the through hole is engaged with the screw, so that the blower can be prevented from falling together with the blower base, thereby improving work safety. You can
