Description

[Detailed Description of the Invention] Industrial Application Field of the Invention This invention is used to connect the internal and external connection wires of an outdoor unit installed under a balcony or suspended from a wall in an air conditioner that performs indoor cooling or heating. Regarding the terminal block mounting structure, the conventional technology shown in Figs. 5 and 6 (above) shows the schematic structure of a conventional outdoor unit that is hung and installed outdoors.As shown in Fig. 5, the outdoor unit On the main body (101), attach the hanging bracket A (103) to the left side panel of the outer box (1'02), and on the right side of the board (107) hanger bracket B (105) is fixed with bolts (not shown). A plurality of hanging bolt mounting holes (106
)iQ Hanging bolts (not shown) are passed through the outdoor unit main body (101), and the outdoor unit body (101) is hung (installed and fixed) in a predetermined position using nuts, etc.

It is designed to insulate and protect it from the outside.

Problems to be Solved by the Invention However, when installing a conventional outdoor unit by hanging it, the position of the terminal block (116) for connecting the internal and external connecting wires (
Top: Located at the top of the left side panel (102) of the outer box,
Tilt the tongue end (102a) toward the inside of the unit,
The terminal block (116) is fixed on its surface. Necessary for wiring work on the surface of the terminal block (116). Window hole (116a) for marking the connection terminal number and visual confirmation of the connection. L, T for hanging the outdoor unit. Because it faces toward the ceiling wall, there is a limit to the viewpoint position when performing visual confirmation.As a result,
However, there are drawbacks such as a space required for installation work between the building wall surface and the location of the outdoor unit terminal block, and the state after installation lacks a sense of unity with the building. In view of the conventional problems, the outdoor unit is configured so that it can be hung tightly on the underside of a building's balcony.In addition, electrical work can be carried out without being restricted by the building wall, and the outdoor unit and building are integrated. The purpose is to ensure a sense of experience and improve the aesthetic appearance of the building.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention (friend) arranges the terminal block fixed to the left side panel of the outer box of the outdoor unit from the top to the bottom and attaches and detaches it via the terminal block mounting box. In addition, even if the connection direction of the refrigerant piping and the internal and external connecting wires are in the same direction, the terminal number display surface of the terminal block should be directed downward, so that the terminal block can be fixed in the same direction. The location is such that you can look up from directly below.

Effects The effects of the above means are as follows.
By combining the terminal block position and the direction of the terminal number display surface, the viewpoint during visual work can be changed from the side of the product to the bottom, eliminating the need for installation work space next to the product and reducing restrictions on outdoor unit installation conditions. In addition, the gap between the building wall and the outdoor unit should be small. When multiple air conditioners are installed in an apartment complex, etc., the location can be selected with priority given to aesthetics. Since the internal and external connecting wires can be connected according to the direction, the work can be easily performed.
Terminal block mounting box power connection Since it is separated from the power supply box to which the main electrical components are installed and can be attached to and detached from the outdoor unit body, electrical connection work can be carried out safely and securely in narrow spaces. DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1, 2, and 3 of the accompanying drawings. In Figure 1, the hanging bracket A is attached to the outdoor unit main body (1).
(3) Power statement And on the right side of the board (7) (Friend hanging bracket B)
(5) is fixed with a bolt (not shown). Hanging bolts (not shown) are passed through the plurality of hanging bolt mounting holes (6) provided in the hanging fittings A (3> and B (5)), and then attached to the outdoor unit body (1) using counter nuts, etc.
) are hung and fixed in place, and the circuit board (7), left front plate (8), right front plate (9), and intake air vent (
9a), air outlet (9b), left top plate (10), right top plate (11), terminal block installation box (12) for connecting internal and external connection wires
), a three-way valve 13) for gas-side piping connection, a two-way valve (14) for liquid-side piping connection, and the like constitute the exterior of the outdoor unit main body (1).

Also, as shown in Figure 2, there is a c'! mark on the bottom of the left side panel (2) of the outer box. ．． A terminal block mounting box (12) is disposed in which a terminal block (15) for connecting the internal and external connecting wires (19) is housed and fixed. Even if this terminal block mounting box (12) i1 is removably attached with multiple screws (17) by tilting the lead-in side of the internal and external connecting wires (19) downward, it is also attached to the left side panel (2) of the outer box (toward the outside). A lead wire hole (2a) is provided on the lower side of the terminal block mounting box to draw the electric wire into the unit.Furthermore, the upper end of the lead-in opening (12b) Lt, which is the part where the internal and external connecting electric wires of the terminal block mounting box are connected, is provided. The refrigerant pipe (l8
) and the internal/external connecting wires (19) are constructed so that their connection directions are the same. Furthermore, as shown in Figure 3, the terminal block (15) has multiple connection holes (19) into which the internal/external connecting wires are inserted.
5a), terminal number (15b), wire fixing release push button (15c), core wire confirmation window (15d) for visually checking the status after connecting wire is inserted, and for connecting to the internal power supply part of the outdoor unit main body. Even if the end f (I5e) is provided, this terminal block (15) li terminal! It is fixed to the cut-and-raised part (12a) provided in <12) with a fixing screw (20) so that it can be attached and detached from the bottom surface.

A resin bushing (2
I) is removably fitted, so by removing the L fixing screw (l9) with the lead wire connected to the terminal (15e), the terminal block (l5) can be attached to the terminal block mounting box (l5).
2) The terminal block cover (16) can be removed and attached from below. The terminal block mounting structure for electrical components makes it possible to effectively utilize the wasted space below the two-way and three-way valves, making it easier to arrange the refrigeration cycle parts and electrical components inside the outdoor unit. Installation of the outdoor unit [・When wiring on the side, all work can be easily performed from below the outdoor unit by changing the viewpoint. The outdoor unit can be installed without being restricted by the gap between the ceiling and the wall, and it can emphasize its integration with the building and help improve the aesthetics. According to ``The three-way valve surface, the three-way valve, and the terminal block mounting box are on the same side, making effective use of space.''
There is no need to increase the external dimensions of the outdoor unit, and since the terminal block mounting box is tilted, it is easy to visually inspect the terminal block from below the outdoor unit. Furthermore, the terminal block can be attached and removed while the wires remain connected in the terminal block mounting box, and the visual confirmation direction and fixing screw operation direction are unified in the same direction, making assembly work in the factory and service in the market easier. Even if workability is improved
