DETAILED DESCRIPTION

[0026] It is easy to understand that according to the technical scheme of the utility model, a person skilled in the art can propose a plurality of structure modes and implementation modes which can be replaced with each other without changing the essential spirit of the utility model. Therefore, the following specific embodiments and drawings are only exemplary description of the technical scheme of the utility model, and should not be regarded as the whole of the utility model or regarded as the limitation or restriction of the technical scheme of the utility model.

[0027] EMBODIMENT

[0028] As Figs. 1-2 shown, an inner and outer machine fan coaxial through-wall type air conditioner comprises:

[0029] The inner machine shell 1 is provided with an air deflector 3 at the air outlet, which can adjust the air outlet direction. The filter screen 6 and fresh air filter cotton 9 and the corresponding electric control device 2 are installed at the air inlet, which are respectively used for filtering impurities in indoor return air and fresh air, and the electric control device 2 controls the operating state of the evaporator.

[0030] The air conditioner main cylindrical pipe 16 is coaxially connected with the mounting end of the inner machine shell 1, the fresh air inlet is provided with an insect screen 13, which can prevent insects and other foreign matters from entering the inside of the air conditioner, the bottom is provided with a drainage groove 4 for collecting condensate water generated during the operation of the air conditioner, and one end is provided with a mounting flange 7, which can be stably fixed with the wall body through the annular mounting surface.

[0031] The double-shaft motor 10 is coaxially arranged in the inner machine shell 1. The first output shaft drives the evaporator fan blade 8, and the second output shaft is coaxially connected with the fresh air fan blade 11 and the condenser fan blade 15 in sequence, so that one motor drives the fan operation of the inner machine and the outer machine at the same time, reduces the number of motors, and optimizes the space layout and energy consumption.

[0032] The evaporator system comprises the evaporator 5 installed in the inner machine shell 1. The evaporator 5 is responsible for absorbing indoor heat to realize heat exchange during refrigeration or heating.

[0033] Condensing system: Located within the cylindrical tube 16 of the air conditioner main body, it includes a condenser 14 and a horizontal air conditioning compressor 17. The condenser 14 cools and liquefies the high-temperature, high-pressure refrigerant. The horizontal air conditioning compressor 17 is arranged axially along the cylindrical tube 16 of the air conditioner main body and is responsible for compressing the refrigerant, causing it to circulate within the system. The bottom of the horizontal air conditioning compressor 17 is equipped with at least three shock-absorbing pads 18 distributed at equal angles to effectively reduce vibration and noise during operation.

[0034] Fresh air control valve: The fresh air control valve 12 is located inside the cylindrical pipe 16 of the air conditioner body. It can adjust the amount of fresh air entering the room to ensure the freshness and circulation of indoor air.

[0035] Cooling mode

[0036] When the cooling mode is activated, the dual-shaft motor 10 starts working. On the indoor unit side, its first output shaft drives the evaporator fan blades 8 to rotate at high speed, causing indoor air to flow rapidly through the evaporator 5. At this time, the low-temperature refrigerant in the evaporator 5 quickly absorbs heat from the air, causing the air temperature to drop significantly. The cooled air is then directionally adjusted by the air guide plate 3 and sent back into the room, achieving indoor cooling.

[0037] On the outdoor unit side, the second output shaft of the dual-shaft motor 10 drives the fresh fan blades 11 and condenser fan blades 15. The fresh fan blades 11 introduce fresh outdoor air, which first passes through the fresh air control valve 12 (the user can adjust the intake as needed), then passes through the fresh air filter cotton 9 to filter impurities, and finally mixes with the cooled indoor air to ensure indoor air quality. The condenser fan blades 15 cause air to flow through the condenser 14, where the high-temperature, high-pressure refrigerant releases heat to the outside and cools and liquefies itself. Afterwards, the horizontal air conditioning compressor 17 takes effect, recompressing the liquefied refrigerant back into a high-temperature, high-pressure state and sending it back to the evaporator 5. This cycle repeats continuously, providing cooling.

[0038] Heating mode

[0039] After switching to heating mode, the four-way valve activates, changing the refrigerant flow direction. At this time, evaporator 5 becomes a condenser, and condenser 14 becomes an evaporator. The dual-shaft motor 10 continues to operate stably, driving the evaporator fan blades 8 and condenser fan blades 15 to rotate. Outdoor air, driven by the condenser fan blades 15, flows through the condenser 14, which has become an evaporator, absorbing the heat released by the refrigerant and heating up to become hot air. This hot air is then blown into the room through the air guide plate 3, warming the space.

[0040] Meanwhile, indoor air flows through the evaporator 5, which has become a condenser, on the indoor unit side. The refrigerant absorbs heat from the air and evaporates. Then it is compressed by the horizontal air conditioning compressor 17, becoming a high-temperature and high-pressure state, and enters the outdoor condenser 14 to release heat, completing the heating cycle and continuously heating the room.

[0041] Wall installation design: the air conditioner is installed through the wall, a 180mm circular hole is drilled on the wall with a water drill, and the cylindrical pipe 16 of the air conditioner body penetrates the wall. At the wall penetration, a special flange is provided for connecting the equipment with the wall. One side of the flange is fixed with the wall, and the other side is designed with quick-release lock buckles connected with the machine body, which is convenient for future disassembly, cleaning and maintenance. The flange is configured with a specially designed sealing and heat insulation assembly to ensure the sealing performance between the wall and the air conditioner, effectively prevent heat conduction, rainwater infiltration and dust from entering the indoor, and improve the energy efficiency ratio of the air conditioner operation and the comfort of the indoor environment.

[0042] The technical scope of the utility model is not limited to the content in the above description, and those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical thought of the utility model, and these modifications and changes should be within the protection scope of the utility model.
