Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to, for example, a ceiling-mounted air conditioner, and more particularly to a vertical grill mounting device in this air conditioner.

[0002]

[Prior Art]

 As shown in FIG. 5, the conventional ceiling-mounted air conditioner has a centrifugal multi-blade fan mounted on a heat exchanger (indoor heat exchanger) 22 and a blower base 23 inside a housing (case body) 21. The blower 24 and the electric component box 25 storing the electric components are arranged and stored, and the drain tray 26 is formed below the heat exchanger 22. As shown in FIG. 6, this drain tray 26 has a box-shaped outer surface formed of a painted iron plate, the outer surface of which is covered with a heat insulating material 27, and the decorative panel 21a of the housing 21 is attached to the lower surface thereof. .. A blow-out grill 28 is formed on the front surface of the housing 21. The blow-out grill 28 has a vertical wind direction adjusting grill 29 and a vertical wind direction correcting vertical grill 29 inside thereof. A grill 30 is formed. When the vertical grill 30 is a ceiling-mounted type, the left and right air outlet directions are generally determined at the time of installation depending on whether the installation location is the central part of the room or the left and right parts. It doesn't change. For this reason, as shown in FIG. 7, the vertical grill 30 is formed by twisting a portion of an iron plate serving as a cut-off grill. The left and right ends 31, 31, 32, 32, 32 of the drain tray 26 and the vertical grill 30 are fixed to the side frame (not shown) of the housing 21 by screws.

[0003]

[Problems to be solved by the device]

 However, in the above-described ceiling-mounted air conditioner, since the drain tray 26 and the vertical grill 30 are made of an iron plate, there is an advantage that the strength of the lower part of the housing 21 can be obtained, but conversely However, there was a problem in terms of installation load, especially because the load to be hung on the ceiling increased. Therefore, in order to reduce the weight of the drain tray 26 and the vertical grill 30, it is considered to use synthetic resin. However, if it is made of resin, the overall weight can be reduced, but on the other hand, the strength of the lower part of the housing will decrease, which may cause chattering noise during operation and deformation of the housing. The problem arises.

On the other hand, in order to improve the strength of the lower portion of the air outlet of the housing, it is conceivable to change the material of the cabinet to a thick one or to add a reinforcing rib. In this case, the material is There arises a problem that the cost or manufacturing cost increases.

In order to solve the above-mentioned problem, the present invention uses a mounting member of a vertical grill to improve the strength of the blowout portion of the casing (case body) by providing a reinforcing rib at the blowout portion of the casing. It is an object of the present invention to provide an air conditioner that is configured to be used for both purposes and has sufficient strength to prevent vibrations due to noise and fins.

[0006]

[Means for Solving the Problems]

 The present invention relates to a ceiling-mounted air conditioner in which a blower and a heat exchanger are built in a housing provided with a suction grill and a blowout grill, and a pair of engagement pieces and a pair of engagement pieces are provided on both side plates of the housing near the blowout grill. Formed facing each other, mounting plates were installed on both engaging pieces, and vertical grills were rotatably erected on the mounting plates with a space therebetween, and connecting rods were connected to the vertical grills. It is a thing.

[0007]

[Action]

 According to the present invention, at the time of assembly, a pair of engaging pieces are formed on both side plates of the housing in the vicinity of the blowout grill so as to face each other, and a mounting plate is horizontally installed on each of the engaging pieces to stop each stopper. Secure with screws and vertically install each vertical grill on this mounting plate at intervals so that it can rotate freely.Connect the connecting rods to each vertical grill, and also use the reinforcing ribs at the outlet to increase strength. It was secured to prevent the generation of vibrations due to noise and fins.

【Example】

 Hereinafter, the present invention will be described with reference to illustrated embodiments.

1 to 4, reference numeral 1 denotes a housing (case body) of a ceiling-mounted air conditioner, and a lower decorative plate 2 is attached to a lower portion of the housing 1. A suction grill 3 is formed in the casing 1 beside the lower decorative plate 2. A blower base 6 in which the suction chamber 4 and the blowout chamber 5 also serve as partition plates is erected in the housing 1, and the blower base 6 located in the suction chamber 4 has a centrifugal blade. A blower 7 such as a fan is attached via a motor base 7a. That is, as shown in the exploded perspective view of FIG. 2, the blower 7 is composed of a motor 8 having a pair of upper and lower fan cases 7b and 7c and a centrifugal multi-blade fan 7d. Further, the housing 1 in the suction chamber 4 is provided with an electric component box 9 for accommodating electric components, and the electric components accommodated in the electric component box 9 are used for the blower and the heat exchange described later. It is configured to control the converter 10.

On the other hand, a heat exchanger (indoor heat exchanger) 10 is installed in an inclined manner in the blowout chamber 5, and a drain tray 11 is laid below the heat exchanger 10. The drain tray 11 is designed so that after the drain generated in the heat exchanger 10 is transferred, it is discharged to the outside by a drain pump (not shown).

On the other hand, an outlet 12 is formed on one side of the housing 1 where the heat exchanger 10 is located, and the housing 1 near the outlet 12 has a fan shape. A blow-out grill 13 is rotatably supported by a support shaft 14, and the blow-out grill 13 regulates the vertical flow of fluid. Further, as shown in FIGS. 3 and 4, a pair of engaging pieces 15 such as ear pieces formed by cutting and raising face each other on both side plates 1a of the casing 1 near the blowout grill 13. A mounting plate 16 is horizontally mounted on both of the engaging pieces 15 and fixed by respective setscrews 17. Further, on the mounting plate 16, each vertical grill 18 is rotatably erected at an interval, and a connecting rod 19 is connected to each of the three vertical grills 18 on each vertical grill 18. Has been done.

A pair of exterior side plates 20 is attached to the outside of the both side plates 1a.

Therefore, according to the present invention, at the time of assembly, the pair of engaging pieces 15 are formed on both side plates 1a of the housing 1 in the vicinity of the outlet grill 13 so as to face each other. By mounting the mounting plate 16 horizontally on 15 and fixing it with each setscrew 17, the reinforcing ribs of the outlet 12 are also used to secure the strength and to prevent vibrations due to noise and cracks. To prevent. Further, according to the present invention, the vertical grills 18 are rotatably erected on the mounting plate 16 with a space therebetween and the connecting rods 19 are connected to the vertical grills 18 to adjust the lateral flow of the fluid. is doing.

[0014]

[Effect of the device]

 As described above, according to the present invention, in an air conditioner in which a blower and a heat exchanger are built in a casing having a suction grill and a blow grill, a pair of side plates of the casing near the blow grill are provided. It is formed so as to face each other with engaging pieces, and mounting plates are installed on both of these engaging pieces, and vertical grills are rotatably erected on the mounting plates at intervals so that they can be connected to the vertical grilles. Since the rods are connected, not only can the reinforcement ribs at the outlet be used as a reinforcement rib to ensure strength, but it is also possible to prevent vibrations due to noise and cracks and to separate the vertical grills. Therefore, the subassembly can be facilitated, and the size of the housing can be determined by the total length of the mounting plate.
