The air conditioner of the present application performs a refrigerating cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and refrigerating or heating an indoor space.

The low-temperature low-pressure refrigerant enters the compressor, the compressor compresses the refrigerant gas into a high-temperature high-pressure state, and the compressed refrigerant gas is discharged. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state formed by condensation in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner may adjust the temperature of the indoor space throughout the cycle.

The section of the upper surface or the lower surface of the end of the plurality of air guide ribs 330 near the fresh air guide opening 240 is parallel to the section of the upper and lower sides of the fresh air connecting part 300 near the fresh air guide opening 240, and the section of the upper surface or the lower surface of the end of the plurality of air guide ribs 330 near the connecting air guide opening 320 is parallel to the section of the upper and lower sides of the fresh air connecting part 300 near the connecting air guide opening 320, so that fresh air smoothly enters the fresh air pipeline 400, and the air loss is reduced.

Since the drainage channel 500 is disposed below the fresh air channel 400, the drainage channel 500 is disposed above the water receiving tray 600, so that the condensation water enters the water receiving tray 600 from the drainage channel 500 through the guide channel 510 disposed on the drainage channel 500, and thus the heights of the fresh air guide port 240 and the connection air guide port 320 are different.

In some embodiments of the present application, the fresh air guide 240 is larger than the connection guide 320 in the front-rear direction of the indoor unit of the air conditioner, the front side of the fresh air connection 300 is parallel to the front side of the fresh air duct 400, and the rear side of the fresh air connection 300 is connected from the fresh air guide 240 to the connection guide 320.

The effect that new trend connecting portion 300 played is mainly under the prerequisite of reducing new trend amount of wind loss as far as, changes the wind direction of new trend, satisfies the problem that new trend wind guide 240 is not on same level with connection wind guide 320, makes the new trend the same through the new trend wind direction of new trend wind guide 240 and connection wind guide 320 through the structure of wind guide muscle 330 that sets up in the inside of new trend connecting portion 300 simultaneously to reduce the amount of wind loss.

0<sin(θ/2)<1/4

Too large an included angle between the upper surface and the lower surface of the diversion angle 450 can cause the diversion effect of the diversion angle 450 to be unobvious, too long the diversion angle 450 can cause the insufficient space of the fresh air pipeline 400, and can cause the reduction of the gap width between the fresh air pipeline 400 and the fresh air guide port 240, thereby reducing the smooth fresh air pressure and balancing the effect of fresh air volume; too short of the diversion angle 450 can not achieve the corresponding diversion effect, so that the beneficial effects of reducing wind resistance and being convenient for diversion can not be achieved, and the length of the diversion angle 450 in the length direction of the fresh air pipeline 400 can achieve the corresponding beneficial effects only in a certain range.

In some embodiments of the present application, the length of the diverter angle 450 along the length of the fresh air duct 400 is any value greater than 10mm and less than 50 mm.

In some embodiments of the present application, the ends of the plurality of diversion angles 450 near the connection air guide 320 are in the same plane, and the plane is parallel to the plane of the connection air guide 320, so that the outdoor air entering the fresh air duct 400 uniformly enters the plurality of fresh air guide cavities 440, thereby ensuring that the air output at the fresh air outlet 430 is substantially uniform.

Under the driving action of the fresh air fan 230, outdoor fresh air enters the second air cavity 225 through the fresh air inlet 280, fresh air enters the first air cavity 212 through the fresh air grille 221 after passing through the filter screen in the second air cavity 225, fresh air enters the fresh air connecting portion 300 through the fresh air guide openings 240, fresh air enters the plurality of connecting air guide cavities 311 through the diversion of the plurality of air guide ribs 330 in the fresh air connecting portion 310, fresh air enters the fresh air pipeline 400 from the fresh air connecting portion 300 through the connecting air guide openings 320, fresh air entering the fresh air pipeline 400 enters the fresh air guide cavities 440 through the diversion of the diversion angle 450, fresh air passes through the buffer portion 420 along the guiding action of the fresh air guide plates 410 and is discharged from the fresh air outlet, an opening 140 is formed in the front side of the shell 100, the area of the opening 140 covers the area of the fresh air outlet 430, and fresh air is discharged from the opening 140 through the fresh air outlet 430 from the fresh air pipeline 400, so that the outdoor-indoor process is completed.

When the weather is hot, the air conditioner needs to refrigerate the indoor air, the indoor heat exchanger 150 works to refrigerate the indoor air, at the moment, the fresh air mode is started, the outdoor air is hotter, and the hotter outdoor air enters the room and is blown onto the body of a user together with the refrigerated indoor air after heat exchange, so that discomfort of the user can be caused, and the experience of the user is reduced; when the weather is cold, the air conditioner needs to heat the indoor air, the indoor heat exchanger 150 works to heat the indoor air, at the moment, the fresh air mode is started, the outdoor air is colder, and the colder outdoor air enters the indoor and the indoor air heated after heat exchange is blown onto the body of the user at the same time, so that discomfort of the user can be caused, and the experience of the user is reduced.
