Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an air conditioner with a drawer-type electric control box. Background Art

[0002] The air conditioner electric control box plays many important roles in the air conditioning system, such as control, protection and monitoring. It is one of the key equipment to ensure the normal operation of the air conditioning system. The maintenance and repair of the air conditioner electric control box is very important to ensure its normal operation and extend its service life. In the existing air conditioner, since the electric control box is fixed inside the air conditioner, it is necessary to take out the air conditioner as a whole when maintaining the electric control box. However, due to the small space inside the air conditioner, it is troublesome to maintain the electric control box, which increases the difficulty of maintenance. Therefore, there is a new type of air conditioner that can take out the electric control box from the air conditioner alone. However, the electric control box of this type of air conditioner usually lacks a mechanism that can fix the posture of the electric control box after it is taken out, which makes the electric control box easy to swing during maintenance. In addition, the position of this type of electric control box in the air conditioner box is low, and it is easy to contact condensed water and cause a short circuit.

[0003] For example, a chiller and energy storage system disclosed in publication number CN216720065U includes a housing, a distribution box, a drive box, a water cooling module and a refrigerant module. The distribution box is retractable and arranged inside the housing, the drive box is detachably arranged inside the housing, the water cooling module and the refrigerant module are arranged side by side inside the housing, and the water cooling module and the refrigerant module are detachably connected. The electric control box of this type of air conditioner usually lacks a mechanism that can fix the posture of the electric control box after it is taken out, which causes the electric control box to swing easily during maintenance, and the electric control box is located at a low position in the air conditioner box, which is easy to contact with condensed water and cause a short circuit. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0027] In one embodiment of the present invention, Figures 1 to 6 As shown, an air conditioner with a pull-out electric control box is provided, comprising a main box body 1, an electric control box 2, a condenser 3, an evaporator 4 and a water supply pump 5. The main box body 1 is divided into a first cavity 11 and a second cavity 12. The front side of the first cavity 11 is connected to the rear side of the second cavity 12. The condenser 3 is installed in the first cavity 11, and the water supply pump 5 is installed at the bottom of the second cavity 12. A support platform 121 is provided in the middle of the second cavity 12, and a guide rail 122 is installed on one side of the top of the support platform 121. The electric control box 2 is slidably connected to the guide rail 122, and the evaporator 4 is installed on the other side of the top of the support platform 121. An inspection port 123 is opened on the front side of the second cavity 12, and the inspection port 123 is provided with a fixing mechanism for maintaining the posture of the electric control box 2.

[0028] Furthermore, the fixing mechanism includes a locking hole 13 and a crossbeam 14, wherein the locking hole 13 is connected to the guide rail 122, and the crossbeam 14 is engaged with the top rear side of the electric control box 2. Specifically, during maintenance, the electric control box 2 is pulled and slid on the guide rail 122, and finally inserted into the locking hole 13, and the top rear side of the electric control box 2 is engaged with the crossbeam 14, and the upper and lower sides of the electric control box 2 are fixed by the locking hole 13 and the crossbeam 14, thereby achieving a good fixing effect.

[0029] Furthermore, a sliding pin 21 is provided at the bottom of the electric control box 2, which is slidably connected to the guide rail 122, and the sliding pin 21 is engaged with the locking opening 13. Specifically, the electric control box 2 is slidably connected to the guide rail 122 through the sliding pin 21 provided at the bottom, and when the sliding pin 21 slides to one end close to the inspection opening 123, it falls downward into the locking opening 13, thereby fixing the position of the electric control box 2.

[0030] Furthermore, a hanging hook 22 is provided at the rear side of the top of the electric control box 2, and the hanging hook 22 is engaged with the cross beam 14. Specifically, when the electric control box 2 slides to the end close to the inspection port 123 through the guide rail 122, the cross beam 14 enters the hanging hook 22 and does not contact the hanging hook 22. When the sliding pin 21 falls to the locking port 13, the top of the hanging hook 22 contacts the cross beam 14, so that the hanging hook 22 is hung on the cross beam 14, thereby fixing the top of the electric control box 2.

[0031] Furthermore, the electric control box 2 is provided with a heat dissipation fin 23 on a side close to the evaporator 4 .

[0032] Furthermore, a dustproof screen plate 124 is detachably connected to the surface of the inspection opening 123 .

[0033] Furthermore, the second cavity 12 is provided with a mounting position 15 for mounting the evaporator 4, and both sides of the mounting position 15 are provided with pin grooves 151. Specifically, the pin grooves 151 are opened obliquely upward, and when the evaporator 4 is mounted, the pins on both sides of the evaporator 4 are slid into the pin grooves 151 to achieve the installation of the evaporator 4 in the mounting position 15, which is convenient for disassembly and maintenance.

[0034] Furthermore, a plurality of cooling fans 16 are provided on one side of the main box body 1 .

[0035] Working principle: During maintenance, the electric control box 2 is pulled and slid out of the inspection port 123 through the guide rail 122. The electric control box 2 is kept in a fixed position through the fixing mechanism. The maintenance personnel can inspect the components in the electric control box 2 more accurately. The electric control box 2 is installed at a relatively high height in the main box body 1, which is more suitable for the maintenance posture of the maintenance personnel. The maintenance personnel can be more relaxed during maintenance, and the electric control box 2 can be prevented from contacting the condensed water in the air conditioner to avoid short circuit.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
