It relates to a box coupling structure.

The configuration of a control box coupled to a conventional air conditioner is shown in FIGS.

That is, the control box 4 is coupled to the lower portion of the discharge port 3 for discharging the low-temperature air generated by the indoor heat exchanger (2).

In addition, a capacitor 9 and a temperature sensing switch 6 also have a rotary switch 7 and many wires 10 connecting them in the control box 4.

However, various components embedded in the control box 4 are very vulnerable to moisture.

That is, a discharge port 3 through which low-temperature air is discharged is formed at an upper side where the control box 4 is located, and the side plate of the discharge port 3 is formed by cold air discharged to the discharge port 3. 5) Dew can form on the outside due to contact with warm air.

Then, the dew flows down to the lower side of the side plate 5 and falls inside the control box 4.

In addition, since the control roll box 4 is coupled to the lower side of the discharge port 3, the area of the discharge port 3 is reduced, so that a large amount of air cannot be supplied to the room and the noise is accompanied. Had

In particular, since the discharge port 3 is formed in contact with one side of the indoor heat exchanger 2 that sucks air in the room, a part of the cold air discharged from the discharge port 3 is not supplied to the room, but is directly supplied to the indoor heat exchanger. Since it was supplied to (2), there was a problem such as lowering the freezing performance.

In order to connect the temperature sensor 8 of the control box 4 to the temperature sensor 8 located in the center of the indoor heat exchanger 2 to detect the temperature of the indoor heat exchanger 2, FIG. Since a long connection wire 11 is required as shown in FIG. 2, the installation of the connection wire 11 has a very troublesome and inconvenient problem.

In addition, in order to repair a plurality of parts and the like mounted on the inside of the control box 4, there was also a problem that the removal of the control box 4 is very uncomfortable.

The purpose of this article for solving and solving such a conventional problem,

It prevents leakage due to dew condensation, condensate inflow and moisture infiltration into the control box of the air conditioner.

Prevents cold air discharged from the discharge port from directly entering the indoor heat exchanger.

It can prevent the noise caused by the small area of the discharge port,

It prevents the low-temperature air discharged from the discharge port directly enters the indoor heat ventilator,

It is possible to save the material by installing a temperature sensor for sensing the temperature of the indoor heat exchanger with a short wire length

The capacitor 141, the temperature sensing switch 151, and the rotary switch 161 are attached to the opening / closing door 124 of the control box 121.

First, in order to fix the capacitor 141 to the opening and closing door 124, the terminal portion of the capacitor 141 is positioned to face downward, and then fixed to the opening and closing door 124 using the band 142.

That is, after the capacitor 141 is wrapped with the band 142, the third through hole 143 formed in the band 142 and the third screw hole 128 formed in the opening / closing door 124 coincide with each other. 144 to fasten the capacitor 141 can be firmly fixed to the opening and closing door 124 as shown in FIGS.

In order to couple the temperature sensing switch 151 to the opening / closing door 124, the control shaft 152 formed on the temperature sensing switch 151 is inserted into the first insertion hole 129 of the opening / closing door 124. The fourth vis 155 is fastened and fixed to the fourth screw hole 153 formed on the upper and lower portions of the temperature sensing switch 151 through the fifth through hole 130 formed in the opening / closing door 124. 5 and 6 can be fixed to the opening and closing door 124 as shown in FIG.

When the wiring of all the wires connected to the control box 121 is completed as described above, the opening and closing door 124 is closed to fix the wires.

At this time, the temperature sensor 156 connected to the temperature sensing switch 151 should be coupled to be located at the center of the indoor heat exchanger 109, the temperature sensor 156 before fixing the opening and closing door 124. ) Through the first hole 135 formed in the control box 121, the second hole 117 formed in the support 113 and the third hole 106 formed in the side wall 104 as shown in Figure 7 When positioned above the center of the unit 109, it is possible to install the temperature sensor 156 with a short wire length.

As described above, when the installation of the temperature sensor 156 is completed, the opening and closing door 124 should be fixed. In this case, the connection part of the opening and closing door 124 and the control box 121 is connected to the hinge 125. Since there is a smooth opening and closing door 124 can be opened and closed.

That is, after closing the opening and closing door 124 to the third through hole 126 formed on the upper and lower sides of the opening and closing door 124 and the second through hole 123 formed in the flange 122 of the control box 121 After inserting the second bis 127 and fastening to the second screw hole 115 formed in the support 113, the opening and closing door 124 can be easily closed and fixed.

In this way, since the control box 121 is coupled between the indoor heat exchanger 109 and the discharge port 110 of the air conditioner 101, it is possible to prevent the dew condensation on the control box 121. It is possible to prevent a short circuit due to inflow of condensate and moisture penetration.

In addition, the air cooled by being introduced into the indoor heat exchanger 109 is supplied to the room through the discharge port 110, and the control box 121 is not connected to the discharge hole 110 and the indoor heat exchanger 109. Since some of the air discharged is not supplied to the indoor heat exchanger 109 and thus all the air is supplied to the room, improved cooling efficiency can be obtained.

In addition, since the discharge port 110 can supply cool air to a room with a larger area, the cooling efficiency can be prevented, as well as the noise generated by the small area of the conventional discharge port can be prevented, thereby providing quiet cooling air.

In particular, since the temperature sensor 156 for detecting the temperature of the indoor heat exchanger 109 can be installed with a short wire length, it is possible to save material and to open the door at the time of repairing the control box 121 ( If only 124 is opened, all parts are exposed, so that the parts can be easily detached and can be repaired very easily and quickly.

In this way, this paper forms a coupling chamber between the indoor heat exchanger and the discharge port of the air conditioner, and combines a control box equipped with various components in the coupling chamber to condense dew and condensate into the control box of the air conditioner. Prevent leakage due to ingress and moisture penetration,

Prevents cold air discharged from the discharge port from directly entering the indoor heat exchanger.

It can prevent the noise caused by the small area of the discharge port,

It prevents the low-temperature air discharged from the discharge port directly enters the indoor heat ventilator,

The temperature detection sensor for detecting the temperature of the indoor heat exchanger can be installed with a short wire length to save the material

The maintenance of the control box has a useful effect to facilitate the removal.
