[0034] As one specific embodiment of the present application, as Figures 1 to 3As shown, the embodiment discloses an air conditioner 100, wherein the air conditioner 100 can include a machine body 200 and at least one air supply pipeline 300, wherein the machine body 200 can include a shell 210 and an evaporator 220, a condenser 230, a compressor 240 and a first fan 250 arranged in the shell 210. The shell 210 can further include a first partition plate 260, which divides the shell 210 into a first accommodating cavity 211 and a second accommodating cavity 212. The evaporator 220 divides the first accommodating cavity 211 into a first sub-cavity 213 and a second sub-cavity 214, and the first fan 250 is located at the first sub-cavity 213. The air supply pipeline 300 includes an air inlet duct 310 and an air return duct 320, the air inlet duct 310 communicates with the first sub-cavity 213, and the air return duct 320 communicates with the second sub-cavity 214. The gas heated by the evaporator 220 is blown into the air inlet duct 310 by the first fan 250 and then flows into a target space 400. The gas in the target space 400 flows into the second sub-cavity 214 through the air return duct 320, and then flows into the first sub-cavity 213 after being heated by the evaporator 220.

[0035] Specifically, the air conditioner 100 of the embodiment can include a machine body 200 and at least one air supply pipeline 300, wherein the machine body 200 can include an evaporator 220, a condenser 230, a compressor 240 and a first fan 250, that is, the machine body 200 contains the components of the indoor unit and the outdoor unit of the traditional air conditioner 100. The air conditioner 100 of the embodiment realizes the purpose of delivering the gas in the machine body 200 to the target space 400 through the air supply pipeline 300. That is, the air conditioner 100 of the embodiment places the evaporator 220, the condenser 230, the compressor 240 and the first fan 250 in the traditional indoor unit and outdoor unit in the same machine, and only delivers the gas to the target space 400 through the air supply pipeline 300, which can effectively reduce the volume of the air conditioner, simplify the structure of the air conditioning machine, and reduce the installation difficulty. At the same time, since there is only the air supply pipeline 300 in the room without the evaporator 220 and the first fan 250 and other machines, the air conditioner 100 makes less sound when blowing air in the target space 400, improving the user experience.

[0036] Specifically, the machine body 200 of the embodiment can be provided with a first partition plate 260, and the shell 210 is divided into two accommodating cavities by the first partition plate 260, and the two accommodating cavities are respectively provided with the evaporator 220 and the condenser 230. The evaporator 220 is arranged at the first accommodating cavity 211 located at the upper side, and the first accommodating cavity 211 is connected with the air supply duct 300, so that the gas is discharged into the target space 400 through the air supply duct 300 after heat exchange by the evaporator 220. The condenser 230 located in the second accommodating cavity 212 exchanges heat for the liquid in the evaporator 220, so as to ensure that the evaporator 220 obtains a suitable heat exchange temperature. The arrangement of the first partition plate 260 also avoids that the gas passes through the space where the evaporator 220 is located and the space where the condenser 230 is located, thereby affecting the heat exchange effect.

[0039] Specifically, the evaporator 220 of the embodiment is arranged in an inclined manner, and the heat exchange area of the evaporator 220 can be increased under the condition that the volume of the machine body 200 is unchanged, thereby further improving the heat exchange efficiency of the evaporator 220 for the gas.

[0042] Specifically, the air uniformizing member 201 forms a containing space with the shell 210, and a plurality of first through holes 202 are arranged on the air uniformizing member 201, so that the air passes through the air inlet 2111 and then flows into the containing space, and then flows to the second sub-cavity 214 through the first through holes 202.

[0043] The air uniformizing member 201 of the embodiment forms a certain containing space with the shell 210, so that the air entering through the air inlet 2111 is buffered and mixed in the containing space first, the uniformity of the air is increased, and then the air flows into the second sub-cavity 214 through the first through holes 202, and the uniformity of the air is further increased.

The size of the air outlet 2112 of the present embodiment is larger than that of the air inlet duct 310, and therefore the size of the first end 510 of the first channel 550 is smaller than that of the second end 520.

[0048] Correspondingly, the structure of the first end 510 of the second channel 560 is the same as that of the air return duct 320, and the structure of the second end 520 of the second channel 560 is the same as that of the air inlet 2111. The size of the air inlet 2111 of the present embodiment is larger than that of the air return duct 320, and therefore the size of the first end 510 of the second channel 560 is smaller than that of the second end 520.

[0051] More specifically, the first partition 260 of the present embodiment is provided with at least one second through hole (not shown in the figure), and the second through hole is located at a position corresponding to the position of the condenser 230.

The present embodiment provides a second through hole at the first partition 260, which can make the condensate water drip down along the second through hole. The second through hole is arranged at a position above the condenser 230, so that the condensate water directly drips on the condenser 230, thereby cooling the condenser 230 and improving the energy efficiency of the whole machine.

When the fresh air valve of the embodiment is opened, the air supply pipeline 300 of the embodiment can reach 1100m 3 / h or even higher. Specifically, the air inlet air volume is related to the pipe diameter of the air supply pipeline 300, and is also related to the power of the centrifugal fan.
