[0076] In the description of the present embodiment, it should be understood that the terms "length", "width", "height", "upper", "lower", "left", "right", "vertical", "horizontal", "bottom", "inner", "outer", "front", "back", and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0077] As one specific embodiment of the present application, as Figures 1 to 4As 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 duct 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. One end of each air supply duct 300 is connected with the machine body 200, and the other end extends to a target space 400. An air inlet air duct 310 and an air return air duct 320 are arranged in the air supply duct 300, and the air inlet air duct 310 and the air return air duct 320 are arranged side by side. The gas after heat exchange by the evaporator 220 is blown into the air inlet air duct 310 by the first fan 250 and then flows into the target space 400. The gas in the target space 400 enters the shell 210 through the air return air duct 320.

[0078] Specifically, the air conditioner 100 of the embodiment can include a machine body 200 and at least one air supply duct 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 supply duct 300 of the embodiment realizes the purpose of transporting the gas in the machine body 200 to the target space 400 through the air inlet air duct 310 and the air return air duct 320, and simultaneously returns the gas in the target space 400 to the machine body 200. That is, the air conditioner 100 of the embodiment places the evaporator 220, the condenser 230, the compressor 240 and the fan in the traditional indoor unit and outdoor unit in the same machine, and only transports the gas to the target space 400 through the air supply duct 300, which can effectively reduce the volume of the indoor machine. Since the indoor space only has the air supply duct 300 without the evaporator 220 and the fan and other machines, the air conditioner 100 makes the sound smaller when blowing air in the target space 400, thereby improving the user experience.

[0079] The air duct type air conditioner 100 of the application has a small size and air return. The core components such as the heat exchanger of the traditional air conditioner 100 are externally arranged, air is supplied through the air supply duct 300, and the air supply duct 300 can be made small in size, thereby realizing the integration of home.

[0080] As one of the embodiments, as shown in Figure 5 and Figure 6 As shown, one machine body 200 of the embodiment can be equipped with one air supply duct 300, and of course, in other embodiments, one machine body 200 can be equipped with multiple air supply ducts 300.

[0081] More specifically, as shown in Figure 6As shown, each air supply duct 300 can include a main duct 330 and at least one branch duct 340, one end of each branch duct 340 being in communication with the main duct 330 and the other end being in communication with the corresponding target space 400 respectively to supply air to the target space 400.

[0082] When one air supply duct 300 is provided for one air conditioner 100 and the target spaces 400 are relatively many, a main duct 330 and a plurality of branch ducts 340 can be used to supply air to different target spaces 400 (as shown in FIG. 4B). Figure 6 When one air supply duct 300 is provided for one air conditioner 100 and the target spaces 400 are relatively many, a main duct 330 and a plurality of branch ducts 340 can be used to supply air to different target spaces 400 (as shown in FIG. 4B). Figure 5

[0083] As another specific embodiment of the present application, the air supply duct 300 of the present embodiment can include a wall-penetrating section 350 for penetrating the cavity to extend the end of the air supply duct 300 into the target space 400, the ratio of the cross-sectional area of the wall-penetrating section 350 to the power of the air conditioner 100 being less than or equal to 57.37 cm 2 / kw, wherein the cross-sectional area of the wall-penetrating section 350 is less than or equal to 200 cm 2 .

[0084] Specifically, the ratio of the cross-sectional area of the wall-penetrating section 350 of the air supply duct 300 of the present embodiment to the power of the air conditioner 100 is less than or equal to 57.37 cm 2 / kw. For example, when the power of the air conditioner 100 of the present embodiment is 1.5 tons or more, the upper limit of the cross-sectional area of the wall-penetrating section 350 should be 200 cm 2 . When the power of the air conditioner 100 is smaller, the cross-sectional area of the wall-penetrating section 350 can be smaller. Specifically, the ratio of the cross-sectional area of the wall-penetrating section 350 of the air supply duct 300 to the power is designed in the present embodiment, on the one hand because the power has a greater limitation on the cross-sectional area, the cross-sectional area of the air supply duct 300 under a certain power is certain, and on the other hand, the cross-sectional area is also limited by the existing laws and regulations and cannot be infinite.

[0085] Specifically, the cross-sectional shape of the wall-penetrating section 350 of the present embodiment can be circular or square or other shapes. In addition, the structure of the general wall-penetrating hole is mostly circular, so the wall-penetrating section 350 of the present embodiment is preferably circular. Preferably, the shape of the wall-penetrating section 350 of the air conditioner 100 of the present embodiment is circular, and the cross-sectional area of the wall-penetrating section 350 is less than or equal to 200 cm 2 ​i.e. less than or equal to 160mm in diameter.

[0086] Specifically, each air supply duct 300 of the present embodiment needs to pass through a wall to enter the target space 400, and therefore, each air supply duct 300 of the present embodiment can include a wall-passing section 350. The wall-passing section 350 of the present embodiment can be circular, and the diameter is less than or equal to 160mm, and the diameter of the wall-passing section matches the case where the power of the air conditioner 100 is greater than 1.5. In this way, on the one hand, the demand for the power of the air conditioner 100 is met, and on the other hand, the demand that the wall hole cannot be too large is also met.

[0087] As a specific embodiment of the present application, as shown in Figures 7-10 each main duct 330 and branch duct 340 of the present embodiment can include a duct body 360 and a first partition 370, wherein the first partition 370 located in the duct body 360 extends along a direction parallel to the extension direction of the duct body 360, and divides the duct body 360 into an air inlet air duct 310 and an air return air duct 320.

[0088] More specifically, the cross-sectional areas of the air inlet air duct 310 and the air return air duct 320 of the present embodiment are the same. In this way, the air volume of the air inlet and the air return can be guaranteed to be equivalent.

[0089] When the air supply duct 300 includes a main duct 330 and a branch duct 340, the air inlet air duct 310 of the main duct 330 and the air inlet air duct 310 of the branch duct 340 are communicated, and the air return air duct 320 of the main duct 330 and the air return air duct 320 of the branch duct 340 are communicated.

[0090] Specifically, when the air supply duct 300 of the present embodiment includes a main duct 330 and a branch duct 340, the wall-passing section 350 is located at the branch duct 340.

[0091] More specifically, the cross-section of the air supply duct 300 of the present embodiment at the wall-passing section 350 can be designed to be circular, while the other located ducts can be designed to be circular (as shown in Figure 9 or other shapes. For example, the duct between the wall-passing section 350 and the fuselage 200 can be designed to be square, such as rectangular (as shown in Figure 10 or square. In this way, on the one hand, the air supply duct 300 is more beautiful and easier to install when it is outside the wall, and on the other hand, the wall-passing section 350 better matches the wall hole.

[0092] As a specific embodiment of the present application, a layer of thermal insulation (not shown in the figure) is provided on the wall of the air supply duct 300 of the present embodiment. The thermal insulation layer can insulate the gas inside the air supply duct 300 from the outside environment and reduce the influence of the outside environment on the temperature of the gas being transported during transportation.

[0093] As a specific embodiment of the present application, as shown in Figure 9 and Figure 10 The air supply duct 300 of the present embodiment is formed by one or more duct units 380, and when the air supply duct 300 is formed by connecting the duct units 380 to each other, the duct units 380 are connected to each other by interlocking to form the entire duct. Specifically, a clasp 390 (as shown in Figure 9 ) is provided at the connection position of the duct unit 380 and the duct unit 380, and the clasp 390 clamps and seals the end portions of the duct units 380 on both sides.

[0094] As a specific embodiment of the present application, as shown in Figure 11 and Figure 12 The end of each air supply duct 300 of the present embodiment is provided with an air outlet duct 500 that communicates with the air inlet duct 310, the extension direction of the air outlet duct 500 is parallel to the air outlet direction of the air inlet duct 310, and the air outlet duct 500 is provided with an air outlet 510, and the gas in the air inlet duct 310 is blown out of the air outlet 510 after flowing into the air outlet duct 500.

[0095] Specifically, the end of the air supply duct 300 of the present embodiment is provided with an air outlet duct 500. When the gas is delivered to the target space 400 by the air supply duct 300, it is blown out through the air outlet duct 500, and the position and direction of the gas flowing out can be controlled through the air outlet duct 500.

[0096] Specifically, the extension direction of the air outlet duct 500 of the present embodiment is parallel to the air outlet direction, which can minimize the loss of gas energy.

[0097] In addition, the cross-sectional area of the air outlet duct 500 of the present embodiment is larger than the cross-sectional area of the end of the air supply duct 300, so as to avoid causing gas energy loss and generating turbulence.

[0098] Specifically, the air outlet 510 of the present embodiment is located at the side wall of the air outlet duct 500 that extends in parallel. In this way, the direction of the gas blown out is perpendicular to the extension direction of the air outlet duct 500.

[0099] Of course, as other embodiments, in order to meet different air outlet requirements, the air outlet 510 and the air outlet direction can be adjusted adaptively.

[0100] Specifically, when the air supply duct 300 includes a main pipe 330 and a branch pipe 340, the end of each branch pipe 340 delivered to the target space 400 is connected with an air outlet duct 500.

[0101] As a specific embodiment of the present application, as shown in Figures 13-16As shown, at least one first baffle 520 is arranged in the air outlet duct 500, and each first baffle 520 is provided with at least one first through hole 521. At least part of the gas in the air outlet duct 500 passes through the first through hole 521 of the first baffle 520 and is blown out from the air outlet 510.

[0102] Specifically, the at least one first baffle 520 arranged in the air outlet duct 500 can block the gas in the air outlet duct 500, so that most or almost all of the gas in the air outlet duct 500 is not blown out from the air outlet 510 after reaching the end of the air outlet duct 500, thereby avoiding uneven air outlet.

[0103] Preferably, a plurality of first baffles 520 are arranged in the air outlet duct 500, and each first baffle 520 is arranged along the extension direction of the air outlet duct 500.

[0104] Specifically, arranging a plurality of first baffles 520 in the air outlet duct 500 along the extension direction of the air outlet duct 500 can further optimize the air volume blown out from the air outlet 510 and further improve the uniformity of air outlet.

[0105] As a specific embodiment of the present application, the outer periphery of at least part of the first baffles 520 is in contact with the inner side wall of the air outlet duct 500, so as to ensure that the gas flowing through the first baffle 520 flows to the rear after passing through the first through hole 521 of the first baffle 520.

[0106] Specifically, the outer periphery of each first baffle 520 is in contact with the side wall of the air outlet duct 500 other than the air outlet.
