Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a blower mounting device for a ceiling-embedded air conditioner.

BACKGROUND ART Conventionally, a ceiling-embedded air conditioner whose main body is embedded in a ceiling has a structure as shown in FIGS. 5 to 8. In FIG. 5, reference numeral 1 denotes a sleeve provided facing the ceiling surface, forming a ventilation path. Reference numeral 2 denotes a blower provided in communication with this sleeve 1. This blower 2 is fixed substantially perpendicularly to a blower fixing plate 3, and has discharge ports 3a and 3b to a heat exchanger 4 provided at an angle. There is. Reference numeral 5 designates fixing parts at both ends of the blower fixing plate 3, and the fixing part 5 at one end is shown enlarged in FIG. In FIG. 6, reference numeral 6 denotes mounting brackets, including a fixing piece 9 fixed to the side plate 7 of the main body by welding 8, and a protruding piece protruding toward the center and formed in an L shape, on which the blower fixing plate 3 comes into contact. 10, and a holding piece 11 for holding the blower fixing plate 3 so that it does not fall in the direction of arrow A. The holding piece 11 is further bent rearward by the thickness of the blower fixing plate 3 with respect to the surface of the protruding piece 10. FIG. 7 is a side sectional view of the blower fixing plate 3 and the mounting bracket 6 in a fixed state;
12 is a blower fixing plate 3 below the mounting bracket 6.
This is a screw for fixing the blower 2 integrated with the blower fixing plate 3 by fastening together the bent piece 13 of the mounting bracket 6 and the bent piece 14 of the mounting bracket 6.

Conventionally, the blower 2, which is integrated with the blower fixing plate 3, is pushed up from below against the mounting bracket 6, which is fixed in advance to the side plates 7, 7 by welding 8, and the blower fixing plate 3 is pushed up from below. The blower 2 is fixed by tightening the screw 12 when the bent piece 14 of the mounting bracket 6 and the bent piece 13 of the blower fixing plate 3 match while touching the protruding piece 10. At this time, the holding piece 11 prevents the blower fixing plate 3 from falling in the direction of arrow A in FIG.

Problems to be Solved by the Invention In such a conventional configuration, when performing maintenance on the blower 2 while the main body is installed facing the ceiling, the screws 12 at both ends are loosened and the blower 2 is moved downward. After pulling it out and performing maintenance on the blower 2, reinstall it. At this time, normally the blower fixing plate 3 is pressed upward while touching the protruding piece 10, and the protruding piece 10 and the holding piece 11
When the bent piece 14 of the mounting bracket 6 and the bent piece 13 of the blower fixing plate 3 match, tighten the screw 12 to fix the blower 2.
The blower fixing plate 3 was accidentally damaged by the protruding piece 10 and the holding piece 11.
If the blower 2 is positioned outside the holding piece 11 as shown in Fig. 8 without being inserted between the two, and the screw 12 is tightened to fix the blower 2, the holding piece 11 will have no effect of preventing it from falling over, and it will be extremely unstable. This causes problems such as abnormal noises such as vibrations being generated during operation of the blower 2, and at the same time creating a dangerous mounting condition.

The present invention is intended to solve these problems, and aims to make it easier to install and remove the blower, and to stabilize the installed state of the blower.

Means for Solving the Problem In order to solve this problem, the present invention includes a fixing piece fixed to both side plates of the main body, a protruding piece on which the blower fixing plate integral with the blower abuts, and this protruding piece. A mounting bracket is fixed to both side plates of the main body, and includes a holding piece located above the blower fixing plate to prevent the blower fixing plate from falling, and a contact piece protruding from the holding piece toward the blower.

Function: With this configuration, when installing the blower fixing plate, if you accidentally try to attach the blower fixing plate diagonally, it will hit the contact piece and prevent you from accidentally attaching it, and prevent the plate from attaching accidentally. The blower fixing plate will be properly fixed with it being sandwiched between the two.

Embodiment Hereinafter, the drawings (first
This will be explained based on FIGS.

In the figure, reference numeral 18 denotes a sleeve provided at the lower part of the main body 19 to face the ceiling surface, and forms a ventilation path for air intake and blowout. A blower 20 communicates with the suction side of the sleeve 18 and is integrated with the blower fixing plate 21. This blower fixing plate 21 is provided with discharge ports 21a and 21b for a heat exchanger 22 for passing cold and hot water, which is provided at an angle. 23 is a drain pan, and 24 is a fixing part at both ends of the blower fixing plate 21. The fixing part 24 on one end side is shown enlarged in FIG. In FIG. 2, reference numeral 25 denotes a mounting bracket, and this mounting bracket 25 includes a fixing piece 28 fixed to the side plate 26 of the main body 19 by welding 27, and a fixing piece 28 bent toward the center to form an L shape to fix the blower. A protruding piece 29 that the plate 21 comes into contact with, a holding piece 30 for holding the blower fixing plate 21 so that it does not fall in the direction of arrow B, and a protruding piece 29 that protrudes from the holding piece 30 toward the blower 20. It consists of a contact piece 31 formed by cutting out the upper part of the . Further, the holding piece 30 is further bent rearward by the thickness of the blower fixing plate 21 with respect to the plane of the protruding piece 29. Third
The figure is a sectional view taken along the line X-X in Figure 2, and 32 is the mounting bracket 2.
The bent piece 33 of No. 5 and the bent piece 34 of the blower fixing plate 21
This is a screw for fixing the blower fixing plate 21 and the blower 20 integral with the blower fixing plate 21 by tightening them together. Normally, when installing the blower fixing plate 21,
1 is pressed upwards while hitting the protruding piece 29 of the mounting bracket 25 to install it. However, if the blower fixing plate 21 is pushed up diagonally by mistake as shown in FIG. , the screws 32 that attach the blower fixing plate 21 cannot be tightened.

In the above configuration, the blower 20, which is normally integrated with the blower fixing plate 21, is fixed at the lower part by screws 32, and at the upper part, the blower fixing plate 21 abuts the protruding piece 29 and is moved rearward by the holding piece 30. is prevented from falling down, and is fixed so as to be sandwiched between the protrusion piece 29 and the holding piece 30. Next, when taking out the blower 20 as necessary for maintenance etc., pull out the sleeve 18 downward and remove each screw 32 at both ends.When reinstalling, hold the blower against the protruding piece 29 and remove it. Push up the fixing plate 21, but if you accidentally push up the blower fixing plate 21 diagonally, the blower fixing plate 21
hits the contact piece 31, and the bent piece 33 of the mounting bracket 25
Since the bent pieces 34 of the blower fixing plate 21 do not come into contact with each other, the screws 32 do not bend against the bent pieces 34 and cannot be attached. When the blower fixing plate 21 is pushed up further diagonally, the blower fixing plate 21 hits the contact piece 32.
It is in a state where it is detached from the air blower 20 side. That is, the angle between the protruding piece 29 and the blower fixing plate 21 becomes large, and the bent piece 33 of the mounting bracket 25 and the bent piece 34 of the blower fixing plate 21 do not come into contact with each other, so that the screw holes are largely misaligned, and Since it is slanted, the screw 32 cannot be attached.

Effects of the invention As described above, according to the invention, since the mounting bracket includes a fixing piece, a protruding piece, a holding piece, and a contact piece, when performing maintenance such as replacing the blower,
It is now possible to correctly and safely attach the blower to the mounting bracket, and maintenance can be performed with peace of mind without worrying about abnormal noises or the blower falling.
The practical effects are great.
