Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning outdoor units, in particular to an air-conditioning unit which is easy to maintain and overhaul. Background Art

[0002] Air conditioning units generally refer to air handling units. In a full air system, the air sent to each designated area is centrally processed in the machine room. The equipment that processes the air is called an air handling unit, or air conditioning unit. The air conditioning unit is used to control the temperature and humidity of the air, and purify the air before transporting it to the designated area. The air conditioning unit includes a treatment room for treating the air and a cold air pipe for transporting the regulated air. In winter, the air temperature in the cold air pipe is higher, and in summer, the air temperature in the cold air pipe is lower. Therefore, the cold air pipe is generally installed outside the treatment room to avoid long-term high or low temperature damage to the air conditioning unit. After the air is processed in the treatment room, the air is transported to the central distribution point for distributing gas through the ventilation pipe for further transportation.

[0003] When the interior of the air-conditioning unit needs to be maintained and inspected, the outer shell of the air-conditioning outer unit needs to be disassembled. However, the exposed area of ​​the outer shell when one side is disassembled is small, which is not convenient for maintenance personnel to observe. In addition, when the outer shell is disassembled and installed, the staff needs to use tools to disassemble and install the bolts, which is time-consuming and laborious. In addition, the bolts are small in size and are easy to lose after removal, which is not convenient for quick installation. Utility Model Content

[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] Embodiment 1

[0044] See also Figure 1-5 , an air conditioning unit that is easy to maintain and overhaul, including a frame assembly 1, the frame assembly 1 includes: a base frame 11, the top of which is movably connected to a top plate 12; a vent hole 13, which is arranged on the rear side wall of the base frame 11; a disassembly assembly 2 is arranged on the base frame 11 and the top plate 12, and the disassembly assembly 2 includes: a rotating rod 21, which is rotatably connected to the top of the top plate 12, and the rotating rod 21 passes through and extends to the bottom of the top plate 12; a turning handle 22, which is arranged on the top of the rotating rod 21; a gear 23, which is fixedly connected to the bottom of the rotating rod 21; a slide groove 241, which is symmetrically opened on the top surface of the top plate 12; a slider 24, which is slidably connected to the slide groove 241; a rack 25, which is symmetrically arranged at the bottom of the slider 24, and is respectively meshed with the gear 23; a plate body 26, which is arranged at different ends of the rack 25; a locking pin 27, which is arranged on different surfaces of the plate body 26; and a socket 271, which is opened on the inner side wall of the base frame 11. The locking pin 27 corresponds to the insertion hole 271 in position, and there are multiple sets of the locking pin 27 and the insertion hole 271. The rack 25 is provided with a limit block 251 at the opposite end.

[0045] When in use, the staff uses the disassembly assembly 2 to complete the disassembly between the bottom frame 11 and the top plate 12: when the top plate 12 needs to be disassembled, the turning handle 22 is turned counterclockwise, and the turning handle 22 drives the turning rod 21 and the gear 23 to rotate. The racks 25 meshing on both sides of the gear 23 slide in the slide groove 241 by the slider 24, and bring the plate body 26 and the locking pin 27 back to the center of the top plate 12 at the same time. At this time, the locking pin 27 is disengaged from the sockets 271 on the front and rear sides of the bottom frame 11, and the top plate 12 is completed. Separation from the base frame 11, at this time the staff removes the entire top plate 12 from the base frame 11, the field of vision is relatively wide, and it is convenient to maintain and repair the air conditioning components in the base frame 11. When installation is required, turn the handle 22 to retract the locking pin 27 to the bottom of the top plate 12, cover the top plate 12 on the base frame 11, turn the handle 22 clockwise to make the locking pin 27 gradually approach the sockets 271 on both sides until it is inserted into the sockets 271, stop turning the handle 22, and complete the installation. Multiple groups of locking pins 27 and sockets 271 increase the firmness of the connection between the top plate 12 and the base frame 11. The limit block 251 limits the movement of the rack 25 to prevent the rack 25 from moving too long, thereby losing the meshing state with the gear 23, and thus losing the effect of quick disassembly between the top plate 12 and the base frame 11.

[0046] Embodiment 2

[0047] On the basis of the first embodiment, an auxiliary function is added.

[0048] See also Figure 1-5The outer wall of the turning handle 22 is provided with anti-slip grooves 221. The rear side wall of the base frame 11 is provided with a defrost assembly 3, and the defrost assembly 3 includes: a bracket 31, symmetrically arranged on the rear side wall of the base frame 11; a reciprocating screw rod 32, rotatably connected between the brackets 31; a motor 33, whose output shaft is fixedly connected to one end of the bracket 31; a threaded block 34, threadedly connected to the reciprocating screw rod 32; a brush plate 35, arranged at the bottom of the threaded block 34, and the brush plate 35 is close to the air vent 13; an optical axis 36, arranged on the rear side wall of the base frame 11 through the bracket 31, and the bottom end of the brush plate 35 is slidably connected to the outside of the optical axis 36. The reciprocating screw rod 32 is externally sleeved with a telescopic sleeve 321.

[0049] The anti-slip pattern 221 increases the friction between the staff's hand and the handle 22, preventing the hand from slipping, saving time and effort. When the air conditioner outdoor unit is in operation, frost is likely to appear at the air vent 13. If it is not removed, it may affect the staff's maintenance. Therefore, the defrosting component 3 is used for processing: the staff starts the motor 33, the motor 33 drives the reciprocating screw 32 to rotate, the threaded block 34 threadedly connected to the reciprocating screw 32 moves back and forth, and the brush plate 35 brushes back and forth on the surface of the air vent 13 to remove the frost on the surface of the air vent 13, which is convenient for the staff to inspect. The optical axis 36 guides the movement of the brush plate 35, increasing the stability of the brush plate 35 when it moves. The telescopic sleeve 321 expands and contracts when the threaded block 34 moves left and right, shielding the reciprocating screw 32 to prevent the reciprocating screw 32 from being exposed to the outside, which is prone to rust and affects the normal movement of the threaded block 34.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
