As shown in fig. 1-3, in order to solve the problem that water is easy to enter into an electric appliance box along a cable after water is fed into an existing vehicle-mounted air conditioner external unit, the threading structure 11 for the vehicle-mounted air conditioner external unit 1 of the utility model comprises a chassis 111 and an electric appliance box 112 arranged on the chassis 111, electric devices (the electric devices comprise a fan 121, a compressor 122 and the like) are arranged in the vehicle-mounted air conditioner external unit 1, the electric devices are connected with a cable 13, because the electric appliance box 112 is used for accommodating the cable 13, a wire inlet 1121 is arranged on the electric appliance box 112, preferably, in order to avoid water from entering at the wire inlet 1121, a rubber ring 1122 capable of retaining water is arranged at the wire inlet 1121, the cable 13 connected with the electric devices is stretched into the electric appliance box 112 through the wire inlet 1121, in order to facilitate the cable 13 to be fixed on the chassis 111, a cable fixing hole 1111 (as shown in fig. 1 and 3) is provided on the chassis 111, preferably, a fixing member is provided on the cable fixing hole 1111, the cable 13 is fixed on the cable fixing hole 1111 through the fixing member, and since the vehicle-mounted air conditioner external unit 1 is provided on the outside of the vehicle, water is easy to enter under some special conditions, when the vehicle-mounted air conditioner external unit 1 enters water, water flows along the cable 13, in order to avoid that water enters into the electric appliance box 112 along the cable 13, the plane of the cable fixing hole 1111 is set to be lower than the plane of the lowest point of the wire inlet 1121, at this time, water flows to the cable fixing hole 1111 along the cable 13, and at this time, the cable fixing hole 1111 is lower than the wire inlet 1121, at this time, water cannot continue to move upwards to the wire inlet 1121, and therefore cannot enter into the electric appliance box 112. As shown in fig. 1, in order to further ensure that water cannot enter the wire inlet 1121 along the cable 13, a boss 1113 is provided on the chassis 111, the electric box 112 is provided on the boss 1113, and the plane in which the boss 1113 is located is set higher than the plane in which the chassis 111 is located. As shown in fig. 2, since the terminal 1123 connected to the cable 13 is provided in the electrical box 112, the terminal 1123 cannot be in contact with water, and thus the plane of the terminal 1123 should be set higher than the plane of the highest point of the inlet 1121, and at this time, the height of the cable 13 at the inlet 1121 is lower than the height of the cable 13 connected to the terminal 1123, so that even if some water enters the electrical box 112 from the inlet 1121, it will not directly contact with the terminal 1123, thereby ensuring the safety of the circuit. As shown in fig. 1, the chassis 111 is provided with a drain hole 1112 and a drain channel 1114, the drain hole 1112 is arranged in the drain channel 1114, so that water entering the vehicle-mounted air conditioner outdoor unit 1 from the outside can be conveniently drained as soon as possible, the occurrence of water storage condition of the chassis 111 is avoided, the plane of the drain hole 1112 is set to be lower than the plane of the chassis 111, and once water stored in the chassis 111 can be immediately drained from the drain hole 1112. Of course, to facilitate drainage of water, the drain 1114 is also located in a lower plane than the chassis 111.
The above-mentioned setting the height of the inlet port 1121 to be higher than the height of the cable fixing hole 1111 can avoid that external water or water entering the vehicle-mounted air conditioner external unit 1 enters the electric appliance box 112 along the cable 13, in addition, the setting of the boss 1113 can not only further increase the height difference between the inlet port 1121 and the cable fixing hole 1111, but also delay the water entering the electric appliance box 112 in the case of the vehicle-mounted air conditioner external unit 1, after the water entering the vehicle-mounted air conditioner external unit 1, the water can fall on the chassis 111, generally, the water is discharged from the water outlet before the water can be stored on the chassis 111, when the water in the vehicle-mounted air conditioner internal unit is more, there may be a problem that the water is slow to be discharged, because the boss 1113 is at a position higher than the chassis 111, the water cannot enter the inlet port 1121, and thus the water is already discharged from the water outlet to the outside of the vehicle-mounted air conditioner external unit 1 before entering the electric appliance box 112 through the inlet port 1121.
The electric device comprises a compressor 122, a fan 121 and other devices, the fan 121 is arranged at the outermost side of the vehicle-mounted air conditioner external unit 1 so that the fan 121 can directly and rapidly exchange heat between air in the vehicle-mounted air conditioner external unit 1 and external air, the compressor 122 and the electric box 112 are arranged at the inner side of the fan 121, meanwhile, the fan 121 is arranged adjacent to a first side of the compressor 122, the electric box 112 is arranged adjacent to a second side of the compressor 122, an included angle between the first side and the second side is approximately 90 degrees, a cable fixing hole 1111 is formed between the compressor 122 and the electric box 112, and a wire inlet 1121 is formed in one side, close to the compressor 122, of the electric box 112. The above arrangement can ensure that the cable 13 of the fan 121 and the compressor 122 can enter the inlet port 1121 of the electrical box 112 without bypassing other devices after being led out from the fan 121 and the compressor 122, thereby reducing the length of the cable 13, and the cable fixing hole 1111 is arranged between the compressor 122 and the electrical box 112, and the leading-out position of the cable 13 from the fan 121 and the compressor 122 is higher than the cable fixing hole 1111, so that if water exists on the cable 13, the water flows from top to bottom to the cable fixing hole 1111, avoiding the risk of water storage of the compressor 122 and the fan 121, and the water at the cable fixing hole 1111 will not continue flowing to the inlet port 1121 because the position of the inlet port 1121 is higher than the position of the cable fixing hole 1111, thereby reducing the possibility of water entering the electrical box 112. In addition, as shown in fig. 3, in order to avoid that the fan 121 throws water to the inlet port 1121 during rotation, the inlet port 1121 is arranged at a position deviated from the air outlet of the fan 121, the air outlet direction of the fan 121 is perpendicular to the air inlet direction of the inlet port 1121, the deviation distance between the inlet port 1121 and the fan blade of the fan 121 is set to be not less than 2cm, and in order to avoid that the cable 13 is excessively long, the deviation distance between the inlet port 1121 and the fan blade of the fan 121 is set to be not more than 20cm.
It should be noted that, the rubber ring 1122 is provided at the wire inlet 1121 to prevent water or other impurities from entering the electrical box 112, and in addition, because the rubber ring 1122 is made of a soft material, when the wire 13 is reciprocally stretched at the wire inlet 1121, the rubber ring 1122 can relieve friction between the wire 13 and the electrical box 112, so as to avoid abrasion of the wire 13.
It should be further noted that the electric device of the present utility model may include the fan 121 or the compressor 122, and may include other devices, which are not limited thereto, and may be configured according to the needs of those skilled in the art, and all the above are within the scope of the present utility model. In the present utility model, the cable 13 led out from the fan 121 and the cable 13 led out from the compressor 122 are collectively referred to as a cable 13.
In addition, the fixing member is fixedly disposed on the cable fixing hole 1111 in advance in the present utility model, and of course, the fixing member may be a separate component, and after the cable 13 is installed, the cable is fixed by using the fixing member, and then the fixing member is disposed at the cable fixing hole 1111, which is not limited, and may be disposed according to the needs of those skilled in the art, which is within the scope of the present utility model.
