Description

[Detailed explanation of the invention] (a) Industrial application field This invention relates to a ceiling-suspended air conditioning unit that is suspended from the ceiling of a room, and a ceiling-embedded air conditioning unit that is embedded in the ceiling space.

(b) Prior art A ceiling-embedded air conditioning unit was developed in 1973, in which a hanging rod is passed through a hole in the top plate of the unit body and fixed with a locking hole provided at the bottom of the unit body.
It is presented in Publication No. 37386.

(c) Problems to be solved by the invention In order to pass the suspension rod from the through hole in the top plate to the locking hole below, the suspension rod must be firmly fixed to the ceiling beam so that it does not sway, and the unit body must be firmly fixed. It was necessary to push it up while keeping it in a horizontal state, which had the problem of poor workability. Another problem is that the suspension rods come into contact with the cold air flow within the unit body and are cooled, resulting in condensation.

(d) Measures to solve the problem This proposal includes a through-hole for the suspension rod that is drilled in the top plate of the unit body, and a locking hole for fixing the suspension rod that is provided below this hole. A guide tool for introducing the suspension rod is provided to straddle the suspension rod.

(e) Function Once the unit body is pushed up and the through hole in the top plate is fitted to the lower end of the suspension rod, the unit will not be suspended even if the unit body is pushed up at a slight angle or even if the suspension rod is dangling. The lower end of the retainer is guided by the guide and reaches the locking hole, making hanging work easier. Furthermore, by covering the suspension rod with the guide, the suspension rod will not come into contact with cold air and cause dew condensation.

(F) Example To explain a ceiling-suspended air conditioning unit as an example, Fig. 1 is an exploded perspective view of the main parts of the air conditioning unit, Fig. 2 is a perspective view of the air conditioning unit, and Fig. 3 is an exploded perspective view of the main parts of the air conditioning unit.
The figure is a cross-sectional view taken at -' in FIG. The unit main body 5 is composed of side panels 3 and 4 that are detachably attached, and after drawing indoor air from the bottom surface and being cooled or heated by a heat exchanger, the front grille 6 of the housing 2 and the side panels 3 ，
The structure is such that cold air or hot air is blown out in three directions from the side grill 7 of 4.

8a, 8b, 8c, 8d are long bolt-shaped suspension rods for hanging the unit main body 5, 9a, 9b, 9
c and 9d are through-holes 1 for penetrating the suspension rods 8a, 8b, 8c, and 8d drilled in the top plate 1 of the unit body 5;
0 is a strong box body with only one side 11 open, located at the four corners of the housing 2, and through holes 9a, 9b, 9c, 9 are formed in the holder 12 forming the upper side plate of this box body.
A locking hole 13 is formed facing the holder 12, and a substantially U-shaped engagement plate 14 is welded and erected on the upper surface of the holder 12.
c, 9d and the suspension rod 8 that straddles the respective locking holes 13
A, 8b, 8c, and 8d guide tools 15 made of synthetic resin are respectively held in between. This guide tool 15 has a cylindrical shape, and its upper and lower edges 16 and 17 are in close contact with the lower surface of the top plate 1 and the upper surface of the holder 12, so that cold air is drawn into the box body 10 during cooling. The suspension rods 8a, 8b, 8c, 8d enter the upper space 18.
This prevents condensation from coming into contact with cold air. 1
A partition plate 9 is welded across the holder 12 and the top plate 1, and serves to prevent cold air from entering the upper space 18 as much as possible and to reinforce the top plate 1. Reference numeral 20 denotes a lid that closes the open side surface 11 of the box body 10, and cold air guided from the side air outlet 21 of the housing 2 to the side grille 7 enters the box body 10, and the suspension rod 8
This is to prevent dew condensation from being cooled by cold air on the parts a, 8b, 8c, and 8d.

22 is a regulating device forming the lower surface of the box body 10;
If the suspension rods 8a, 8b, 8c, 8d are too long,
This prevents the lower end 23 of the suspension rod from accidentally puncturing the drain pan 24 made of Styrofoam.

Reference numeral 25 indicates the position of the through holes 9a, 9b, 9c, and 9d, and a total of six arrow stickers are pasted on the front side and left and right side surfaces 26 of the unit body 5. The position of 9b is the display part 25
The positions of the rear through holes 9c and 9d at the intersections on the extension lines 27 and 27 of the display portions 25c and 25b are respectively visible from the side of the unit body 5 through the extension lines 28 of the display section 25c.

Reference numeral 29 denotes a suspension rod 8a that projects downward from the locking hole 13 by inserting a hand through the open side surface 11 of the box body 10;
Nuts 31 are washers that are screwed into the screw portions 30 of 8b, 8c, and 8d.

The structure is as described above, and when the hanging position of the unit body 5 is determined, the square hole 32 that is equal to the width and depth of the protruding top plate 1 is first inserted into the ceiling plate 3.
Measure the distance between the suspension rods 8a, 8b, 8c, and 8d to be equal to the distance between the through holes 9a, 9b, 9c, and 9d, and connect the upper ends of the suspension rods to the ceiling beams (not shown). Fixed to. As shown in FIG.
, and while checking the positions of the front through holes 9a and 9b on the display sections 25a and 25b, insert both the through holes 9a and 9b into the suspension rods 8a and 8b.
The through holes 9c and 9d on the rear side are also spaced at the same distance so that the suspension rod 8
c and 8d at the same time. In this case, positioning can be performed more reliably by checking the positions of the rear through holes 9c and 9d on the display section 25c.
Then, the unit main body 5 is further pushed up with the through holes 9a, 9b, 9c, and 9d fitted into the four suspension rods 8a, 8b, 8c, and 8d, respectively. At this time, even if the unit main body 5 is pushed up with some inclination, the lower ends 23 of the suspension rods 8a, 8b, 8c, and 8d, which are once fitted into the through holes 9a, 9b, 9c, and 9d, are guided by the guide tool 15. It protrudes downward from the locking hole 13, and the front upper wall 34 of the unit main body 5 comes into contact with the ceiling plate 33. In this state, insert the washers 31 into the screws 30 of the suspension rods 8a, 8b, 8c, and 8d and tighten them with the nuts 29, then cover the lid 20 and attach the side panels 3 and 4 to complete the hanging work. The unit main body 5 is suspended and fixed in a so-called semi-embedded state in which the upper half thereof is embedded above the ceiling plate 33.

In addition, when the top plate 1 is brought into contact with the ceiling plate 33 as shown by the two-dot chain line in FIG. 3, and the entire unit body 5 is exposed below the ceiling plate 33, Compared to the case, the suspension rods 8a, 8b,
Since the lower ends 23 of 8c and 8d protrude further from the square hole 32 of the ceiling plate 33, positioning using the display section 25 becomes easier, but since the entire unit body 5 is exposed to the room, a pressure sensation cannot be avoided.

(g) Effects of the invention The air conditioning unit of the present invention has a through-hole for the suspension rod that is drilled in the top plate of the unit body, and a locking hole for fixing the suspension rod that is provided below the through-hole. I installed a guide for introducing the suspension rod across the
Once the unit body is pushed up and the through hole in the top plate is fitted to the lower end of the suspension rod, it will not work even if the unit body is tilted slightly and pushed up, or even if the suspension rod hangs loosely.
Since the lower end of the hanging rod is guided by the guide and reaches the locking hole, the hanging work can be easily performed.

Furthermore, the guide can also be used as a dew condensation prevention device that prevents dew condensation due to the suspension rod being cooled by cold air.
