[0083] In the description of this embodiment, it should be understood that the terms "length", "width", "height", "up", "down", "left", "right", "vertical", "horizontal", "bottom", "inside", "outside", "front", "back", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0084] As a specific embodiment of the present invention, Figures 1 to 4 As shown, the present embodiment discloses an air conditioner 100, wherein the air conditioner 100 may include a body 200 and at least one air supply duct 300, wherein the body 200 may 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 to the body 200, and the other end extends to the target space 400. An air inlet duct 310 and a return air duct 320 are arranged in the air supply duct 300, and the air inlet duct 310 and the return air duct 320 are arranged side by side. The gas after heat exchange in the evaporator 220 is blown into the air inlet duct 310 by the first fan 250 and then flows into the target space 400, and the gas in the target space 400 enters the shell 210 through the return air duct 320.

[0085] Specifically, the air conditioner 100 of this embodiment may include a body 200 and at least one air supply duct 300, wherein the body 200 may include an evaporator 220, a condenser 230, a compressor 240 and a first fan 250, that is, the body 200 includes components of an indoor unit and an outdoor unit of a conventional air conditioner 100. The air supply duct 300 of this embodiment achieves the purpose of transporting the gas in the body 200 to the target space 400 through the air inlet duct 310 and the air return duct 320, and at the same time, the gas in the target space 400 flows back into the body 200. That is, the air conditioner 100 of this embodiment places the evaporator 220, condenser 230, compressor 240 and fan in the traditional indoor and outdoor units 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. At the same time, since there is only the air supply duct 300 but no evaporator 220, fan and other machines in the room, the air conditioner 100 makes less noise when blowing air in the target space 400, thereby improving the user experience.

[0086] The present invention provides a small-sized duct-type air conditioner 100 with return air. The core components such as the heat exchanger of the traditional air conditioner 100 are externally arranged, and air is supplied through the air supply duct 300. The air supply duct 300 can be made into a small volume, thereby achieving home integration.

[0087] As one of the embodiments, Figure 5 and Figure 6 As shown, one fuselage 200 of the present embodiment may be equipped with one air supply duct 300 . Of course, in other embodiments, one fuselage 200 may be equipped with a plurality of air supply ducts 300 .

[0088] More specifically, Figure 6 As shown, each air supply duct 300 may include a main pipe 330 and at least one branch pipe 340 , one end of each branch pipe 340 is connected to the main pipe 330 , and the other end is connected to the corresponding target space 400 to supply air to the target space 400 .

[0089] When one fuselage 200 is equipped with one air supply duct 300, and there are many target spaces 400, one main pipe 330 and multiple branch pipes 340 can be used to supply air to different target spaces 400 (e.g. Figure 6 When a fuselage 200 is equipped with multiple air supply ducts 300, and there are many target spaces 400, each air supply duct 300 may include a main pipe 330, and the number of target spaces 400 and the number of air supply ducts 300 are matched, and each air supply duct 300 may supply air to one of the target spaces 400 (such as Figure 5 shown).

[0090] As another specific embodiment of the present invention, the air supply duct 300 of this embodiment may include a wall-penetrating section 350, which is used to pass through the cavity so that the end of the air supply duct 300 extends into the target space 400, and the ratio of the cross-sectional area of ​​the wall-penetrating section 350 to the power of the air conditioner 100 is less than or equal to 57.37 cm 2 / kw, wherein the cross-sectional area of ​​the through-wall section 350 is less than or equal to 200cm 2 .

[0091] 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 cross-sectional area of ​​the wall-penetrating section 350 and the power of the air conditioner 100 is less than or equal to 57.37 cm 2 For example, when the power of the air conditioner 100 of the wall-penetrating section 350 of this embodiment is 1.5 hp or above, the upper limit of the cross-sectional area of ​​the wall-penetrating section 350 is 200 cm 2 When the power of the air conditioner 100 is smaller, the cross-sectional area of ​​the through-wall section 350 can be smaller. Specifically, the ratio of the cross-sectional area of ​​the through-wall section 350 of the air supply duct 300 to the power is designed in this embodiment. On the one hand, the power has a large restriction on the cross-sectional area. The cross-sectional area of ​​the air supply duct 300 under a certain power is certain. On the other hand, it is limited by existing laws and regulations, and the cross-sectional area cannot be infinite.

[0092] Specifically, the cross-sectional shape of the wall-penetrating section 350 of the present embodiment may be circular, square or other shapes. In addition, the structure of a 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 , that is, the diameter is less than or equal to 160mm.

[0093] Specifically, each air supply duct 300 of the present embodiment needs to pass through the wall to enter the target space 400. Therefore, each air supply duct 300 of the present embodiment may include a wall-penetrating section 350. The wall-penetrating section 350 of the present embodiment may be circular, and the diameter is less than or equal to 160 mm, and the diameter of the wall-penetrating section is matched with the case where the power of the air conditioner 100 is greater than 1.5 HP. In this way, the power requirement of the air conditioner 100 is met on the one hand, and the requirement that the wall-penetrating hole cannot be too large is also met on the other hand.

[0094] As a specific embodiment of the present invention, Figure 7-10As shown, each main pipe 330 and branch pipe 340 of the present embodiment may include a tube body 360 and a first partition plate 370, wherein the first partition plate 370 is located inside the tube body 360, and the first partition plate 370 extends in a direction parallel to the extension direction of the tube body 360, thereby separating the tube body 360 to form an air inlet duct 310 and an air return duct 320.

[0095] More specifically, the cross-sectional areas of the air inlet duct 310 and the air return duct 320 of this embodiment are the same, so that the air volumes of the air inlet and the air return can be equal.

[0096] When the air supply duct 300 includes the main pipe 330 and the branch pipe 340 , the air inlet duct 310 of the main pipe 330 is communicated with the air inlet duct 310 of the branch pipe 340 , and the air return duct 320 of the main pipe 330 is communicated with the air return duct 320 of the branch pipe 340 .

[0097] Specifically, when the air supply duct 300 of this embodiment includes the main pipe 330 and the branch pipe 340 , the wall-penetrating section 350 is located at the branch pipe 340 .

[0098] More specifically, the cross section of the air supply duct 300 at the wall penetration section 350 of this embodiment can be designed to be circular, and the cross section of the ducts at other locations can be designed to be circular (such as Fig. 9 For example, the duct between the through-wall section 350 and the fuselage 200 can be designed to be square, such as a rectangular shape (such as Fig.10 Such a design can make the air supply duct 300 more beautiful and more convenient to install when it is outside the wall, and the wall penetration section 350 can better match the wall penetration hole.

[0099] As a specific embodiment of the present invention, a heat-insulating layer (not shown in the figure) is provided on the wall of the air supply duct 300 of this embodiment. The heat-insulating layer can keep the gas in the air supply duct 300 warm and isolate it from the external ambient temperature, thereby reducing the influence of the external environment on the temperature of the transported gas during the transport process.

[0100] As a specific embodiment of the present invention, Fig. 9 and Fig.10 As shown, the air supply duct 300 of this embodiment is formed by one or more duct units 380. When the air supply duct 300 is formed by connecting multiple duct units 380, the multiple duct units 380 are interlocked and spliced ​​to form the entire duct. Specifically, a clamping ring 390 (such as Fig. 9 As shown), the clamping ring 390 clamps the ends of the pipe units 380 on both sides together and seals them.

[0101] As a specific embodiment of the present invention, Fig.11and Fig.12 As shown, an air outlet duct 500 connected to the air inlet duct 310 is provided at the end of each air supply duct 300 of the present embodiment, and the extension direction of the air outlet duct 500 is parallel to the air outlet direction of the air inlet duct 310, and an air outlet 510 is provided at the air outlet duct 500, and the gas in the air inlet duct 310 flows into the air outlet duct 500 and is blown out from the air outlet 510.

[0102] Specifically, the end of the air supply duct 300 of this embodiment is provided with an air outlet duct 500. When the gas is transported 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 outflow can be controlled by the air outlet duct 500.

[0103] Specifically, the direction in which the air outlet duct 500 of this embodiment extends is parallel to the air outlet direction, which can minimize the loss of gas energy.

[0104] In addition, the cross-sectional area of ​​the air outlet duct 500 of this embodiment is larger than the cross-sectional area of ​​the end of the air supply duct 300, thereby avoiding gas energy loss and turbulence.

[0105] Specifically, the air outlet 510 of this embodiment is located at the side wall of the air outlet duct 500 which is parallel to the extension direction, so that the direction of the finally blown air is perpendicular to the extension direction of the air outlet duct 500.

[0106] Of course, as other embodiments, in order to meet different air outlet requirements, the air outlet 510 and the air outlet direction can be adaptively adjusted.

[0107] Specifically, when the air supply duct 300 includes a main pipe 330 and a branch pipe 340 , an end of each branch pipe 340 that delivers air to the target space 400 is connected to an outlet duct 500 .

[0108] As a specific embodiment of the present invention, Figure 13-16 As shown, the air outlet duct 500 of this embodiment is provided with at least one first baffle 520 which is basically perpendicular to the extension direction of 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 then is blown out from the air outlet 510.

[0109] Specifically, at least one first baffle 520 is provided in the air outlet duct 500 of this embodiment to block the gas in the air outlet duct 500, preventing most or almost all of the gas in the air outlet duct 500 from being blown to the end of the air outlet duct 500 and then blown out from the air outlet 510, thereby avoiding uneven air output.

[0110] Preferably, in this embodiment, a plurality of first baffles 520 are disposed in the air outlet duct 500 , and the plurality of first baffles 520 are arranged at intervals along the extension direction of the air outlet duct 500 .

[0111] Specifically, along the extension direction of the air outlet duct 500, a plurality of first baffles 520 are provided in the air outlet duct 500 to further optimize the air volume blown out from the air outlet 510 and further improve the uniformity of the air outlet.

[0112] As a specific embodiment of the present invention, the outer periphery of at least part of the first baffle 520 of this embodiment contacts the inner wall of the air outlet duct 500, thereby ensuring that all the gas flowing through the first baffle 520 passes through the first through hole 521 of the first baffle 520 and then flows to the rear.

[0113] Specifically, the outer periphery of each first baffle 520 contacts the side wall of the air outlet duct 500 where the air outlet is not located.

[0114] Specifically, the cross-sectional shape of the first through hole 521 of the present embodiment may be circular, elliptical, square, etc. Preferably, the shape of the first through hole 521 of the present embodiment is circular.

[0115] Preferably, all the first baffles 520 of this embodiment are arranged parallel to each other.

[0116] Preferably, all the first baffles 520 of the present embodiment are perpendicular to the extension direction of the air outlet duct 500 , and the shapes of all the first baffles 520 are consistent with the cross-sectional shape of the side wall of the air outlet duct 500 .

[0117] Specifically, the cross-sectional shape of the air outlet duct 500 of this embodiment is a triangle, and the cross-sectional shape of the first baffle 520 is also a triangle.

[0118] As a specific embodiment of the present invention, the ratio of the cross-section of the first through hole 521 of the first baffle 520 to the cross-sectional area of ​​the entire first baffle 520 gradually increases from the position of the air inlet duct 310 to the position away from the air inlet duct 310.

[0119] Specifically, since the wind speed is higher near the air inlet duct 310 and lower at a position away from the air inlet duct 310, such a design can ensure that the wind speed of the gas blown out from the air outlet duct 500 is equivalent at a position near the air inlet duct 310 and at a position of the air inlet duct 310, so that the blown gas has good uniformity and improves the user experience.

[0120] Specifically, the cross-sectional area of ​​the first through holes 521 of the first baffle 520 of the present embodiment may be changed by changing the number of the first through holes 521 or by changing the cross-sectional area of ​​each first through hole 521 .

[0121] As a specific embodiment of the present invention, the density of the first baffle 520 of this embodiment gradually decreases in a direction from a position close to the air inlet duct 310 to a position far away from the air inlet duct 310 .

[0122] Specifically, in this embodiment, the density of setting the number of first baffles 520 near the air inlet duct 310 is large, while the density of setting the number of first baffles 520 far from the air inlet duct 310 is small. In this way, the air flow speed near the air inlet duct 310 can be equivalent to the air flow speed far from the air inlet duct 310, thereby improving the uniformity of the gas blown out of the air outlet 510.

[0123] As a specific embodiment, the density of the first baffle 520 set at the air outlet duct 500 and the cross-sectional area of ​​the first through hole 521 at the first baffle 520 can be designed according to the situation, so that the gas at different positions of the air outlet 510 of the air outlet duct 500 is ultimately blown out with good uniformity.

[0124] More specifically, the aperture size of the first through hole 521 at the first baffle 520 of this embodiment is adjustable. The total cross-section of the first through hole 521 at each first baffle 520 can be changed, thereby changing the ratio of the total cross-sectional area of ​​the first through hole 521 to the cross-sectional area of ​​the first baffle 520, thereby further improving the uniformity of the exhaust gas.

[0125] As another embodiment, the first baffle 520 of this embodiment can be set with different areas at different distances from the air inlet duct 310, so as to further increase the uniformity of the air outlet.

[0126] As a specific embodiment of the present invention, Figure 13-16 As shown, a second baffle 530 is disposed at the air outlet 510 of the air outlet duct 500 of this embodiment. The second baffle 530 is provided with at least one second through hole 531, and the gas of the air outlet duct 500 passes through the second through hole 531 before being blown out.

[0127] Specifically, in this embodiment, a first through hole 521 of a first baffle 520 is provided at the air outlet duct 500 , and a second baffle 530 is provided at the air outlet 510 , and a second through hole 531 is provided at the second baffle 530 , so as to further increase the uniformity of air outlet from the air outlet duct 500 .

[0128] As a specific embodiment of the present invention, a third baffle 540 is further provided at the air outlet 510 of the air outlet duct 500 of this embodiment. The third baffle 540 is located on the outer side of the second baffle 530 so that the gas blown out from the second baffle 530 passes through the third baffle 540 and then blown out.

[0129] Specifically, in this embodiment, the gas blown out from the second baffle 530 further passes through the third baffle 540 before being blown out, thereby further improving the uniformity of the air output.

[0130] Specifically, the third baffle 540 of this embodiment can be designed as a filtering structure (such as Fig.11 and 12 As shown in FIG. 1 , a filter screen is arranged in the center of the frame structure to obtain the filtering structure of the present embodiment. As another specific embodiment, the third baffle 540 of the present embodiment can be designed as a horizontal strip-shaped grid line structure (such as Fig.13 and Fig.14 As shown in FIG. 1 , the direction of the wind can be adjusted by adjusting the number and direction of the grid line structure. As another specific embodiment, the third baffle 540 of this embodiment can also be designed as a partition with holes (such as Fig.15 and Fig.16 As shown), and the size and distribution of the holes on the partition can be designed according to actual conditions. Specifically, the aperture of the holes on the partition in this embodiment is large in the middle and small on both sides.

[0131] Specifically, in this embodiment, a first baffle 520, a second baffle 530 and a third baffle 540 are arranged at the air outlet duct 500, and three levels of uniform wind are achieved through the three components, so that the gas blown out from the air outlet duct 500 has good uniformity and almost no wind feeling, thereby improving the user experience.

[0132] As a specific embodiment of the present invention, Fig.17 and Fig.18 As shown, the air outlet duct 500 of this embodiment is further provided with a wind shield 550 and wind guide mechanisms 560 located on both sides of the wind shield 550 at the air outlet 510 , and the wind guide mechanisms 560 guide the gas blown out of the air outlet 510 toward the direction away from the wind shield 550 .

[0133] Specifically, in this embodiment, a wind shield 550 and an air guiding mechanism 560 are disposed at the air outlet 510 of the air outlet duct 500. The wind shield 550 is located in the middle of the air outlet 510, and the air guiding mechanism 560 guides the gas blown out from the air outlet 510 to a position away from the middle, thereby preventing the wind in the gas blown out from the air outlet 510 from being blown directly toward the user, thereby improving the user experience.

[0134] Specifically, the air guiding mechanism 560 of the present embodiment may be rotatably connected to the tube wall of the air outlet duct 500 , and the direction of the gas blown out from the air guiding mechanism 560 may be controlled by controlling the rotation of the air guiding mechanism 560 .

[0135] Specifically, the air guide mechanism 560 of this embodiment may include a plurality of air guide blades arranged in parallel, each of which is rotatable. The plurality of air guide blades may rotate individually or in a linked manner.

[0136] As a specific embodiment of the present invention, Fig.11 As shown, the air outlet duct 500 of this embodiment may include a plurality of air outlet modules 501 connected and communicated with each other. Two adjacent air outlet modules 501 are mutually clamped and installed. A first baffle 520 extending in a vertical direction may be provided in each air outlet module 501. A second baffle 530 and a third baffle 540 are provided at the air outlet 510 of each air outlet module 501. A windshield 550 and an air guide mechanism 560 are also provided at the air outlet 510 of each air outlet module 501.

[0137] As a specific embodiment of the present invention, Fig.19 As shown in FIG. 20 , the air outlet duct 500 of this embodiment may further include a side wall 570, which is installed at the target object 600 to be installed, so that the air outlet duct 500 is exposed when installed on the target object. The plane where the air outlet 510 is located forms a continuous surface with the side wall surface 601 of the target object 600 located at least on one side of the air outlet 510.

[0138] Specifically, the target object of this embodiment can be a specific object in the target space 400, such as a room or a cabinet. As one of the embodiments, when the air outlet duct 500 is set on the target object, the air outlet 510 of the air outlet duct 500 is exposed, and the plane where the air outlet 510 is located forms a continuous surface with the side wall surface 601 of the target object 600 located on at least one side of the air outlet 510 (such as Fig.19 , Fig.21 and Fig. 22 As shown), the air outlet duct 500 and the target object 600 do not look out of place, thereby making the air outlet duct 500 look beautiful when installed on the target object 600.

[0139] Specifically, a substantially continuous surface may be formed between the plane where the air outlet 510 of the air outlet duct 500 of the present embodiment is located and at least the exposed surface 601 of the target object 600 located on one side of the air outlet 510 .

[0140] For example, when the cross section of the air outlet duct 500 is a triangle (such as Fig.19 As shown), when the target object is a wall in a room, it can be set at a position between the top and the side wall of the room, with only the air outlet 510 exposed, and the plane where the air outlet 510 is located forms a continuous broken line surface with the surface of the ceiling and the side wall.

[0141] When the cross section of the air outlet duct 500 is a quadrilateral, Fig. 20, two of the side edges can be installed with the top and side walls of the target object 600, and the air outlet 510 can be set at one of the other two side edges or at both of them.

[0142] Preferably, when the cross section of the air outlet duct 500 is a quadrilateral, Fig.21 and Fig. 22 As shown, a substantially continuous surface is formed between the plane where the air outlet 510 is located and the side wall surface 601 of the target object 600 located around the air outlet 510 .

[0143] More preferably, if Fig. 22 As shown, the plane where the air outlet 510 of this embodiment is located is in the same plane as the side wall surface 601 of the target object 600 near the air outlet 510. At this time, it is necessary to open a mounting groove at the target object 600, and embed the air outlet duct 500 into the mounting groove, leaving only the air outlet surface 502 or the air outlet 510 exposed.

[0144] More specifically, the continuity described in this embodiment does not mean that the air outlet or the air outlet cover and the outside of the side wall must be strictly on the same plane, curved surface or folded surface. When the air outlet 510 or the air outlet surface 502 protrudes or recesses about 1-2 cm outside the side wall, it can also be regarded as a continuous surface or the same plane.

[0145] As a specific embodiment of the present invention, Fig.23 and Fig.24 As shown, a mounting structure is provided at the side wall 570 of the air outlet duct 500 of this embodiment, and the mounting structure may include a magnetic attraction structure or a clamping structure to attract or clamp with the mounting bracket 580 at the target object 600 so that the air outlet duct 500 is installed at the target object 600. Specifically, one mounting bracket 580 may be installed with one air outlet module 501, or multiple air outlet modules 501 may be installed.

[0146] Specifically, Fig.24 As shown, a clamping structure 581 is provided on a mounting bracket 580 of this embodiment, and a structure corresponding to the clamping structure 581 is provided at the side wall 570 of the air outlet duct 500. When installing the air outlet duct 500, the mounting bracket 580 and the target object 600 can be fixed first, and then the air outlet duct 500 can be clamped at the clamping structure 581 of the mounting bracket 580. The mounting bracket 580 of this embodiment can install two air outlet modules 501 at the same time.

[0147] Of course, as other embodiments, the connection between the mounting bracket 580 and the mounting structure can be other snap-on forms, and the air outlet duct 500 cooperates with the mounting bracket 580 on the target object 600, so that the air outlet duct 500 can be quickly and flexibly installed on the target object 600.

[0148] As a specific embodiment of the present invention, the cross section of the air outlet duct 500 of this embodiment is a right triangle, the hypotenuse is the air outlet surface, and the two right-angled sides are the installation surface or the fitting surface. The two right-angled sides are respectively attached to the top and side wall of the room (i.e., the target object), and only the surface where the air outlet 510 is exposed. The right-angled sides can also be provided with installation components for installation at the top and / or side wall.

[0149] More specifically, each mounting bracket 580 of this embodiment may include a connecting portion 582 and a mounting portion 583. The connecting portion 582 connects the mounting portion 583, and the mounting bracket 580 is connected to the target object 600 through the connecting portion 582. The mounting portion 583 cooperates with the mounting structure to connect the air outlet duct 500 to the mounting bracket 580.

[0150] As a specific embodiment of the present invention, Fig.25 and Fig.26 As shown, the shell 210 of this embodiment may include a second partition 260, which divides the shell 210 into a first accommodating cavity 211 located at the top and a second accommodating cavity 212 located at the bottom. The evaporator 220 and the first fan 250 are located in the first accommodating cavity 211, and the condenser 230 is located in the second accommodating cavity 212.

[0151] Specifically, the fuselage 200 of this embodiment can be provided with a second partition 260, and the housing 210 is divided into two accommodating chambers by the second partition 260, and the two accommodating chambers are respectively provided with an evaporator 220 and a condenser 230. In this embodiment, the evaporator 220 is provided in the first accommodating chamber 211 located at the top, and the first accommodating chamber 211 is connected to the air supply duct 300, so that the gas is heat exchanged through the evaporator 220 and then flows out from the air supply duct 300 into the target space 400. The condenser 230 located in the second accommodating chamber 212 exchanges heat for the liquid in the evaporator 220, ensuring that the evaporator 220 obtains a suitable heat exchange temperature. The provision of the second partition 260 also prevents the gas from passing through the space where the evaporator 220 is located, and then passing through the space where the condenser 230 is located, thereby affecting the heat exchange effect.

[0152] More specifically, at least one third through hole (not shown in the figure) is provided at the second partition 260 of this embodiment, and the third through hole is located at a position corresponding to the position of the condenser 230. Specifically, since condensed water is likely to appear when the evaporator 220 exchanges heat with the gas, the condensed water will flow down the evaporator 220 and drip below. A water receiving tray can be provided below the evaporator 220, or the second partition 260 is the water receiving tray. In this embodiment, a third through hole is provided at the second partition 260, so that the condensed water can drip downward along the third through hole. The third through hole is provided at a position above the condenser 230, so that the condensed water is directly poured on the condenser 230, thereby cooling the condenser 230 and improving the energy efficiency of the whole machine.

[0153] As another specific embodiment of the present invention, the second partition 260 of this embodiment is tilted, and the second partition 260 is tilted toward the side with the condenser 230. Specifically, the second partition 260 of this embodiment can be set at an inclination angle, so that the condensed water can flow along the second partition 260 toward one side, and finally drip on the condenser 230, so as to cool the condenser 230 and improve the energy efficiency of the whole machine.

[0154] As a specific embodiment of the present invention, the shell 210 of this embodiment may also include a third partition 270 arranged in the first accommodating chamber 211, the third partition 270 divides the first accommodating chamber 211 into a first sub-chamber 213 and a second sub-chamber 214, the evaporator 220 is arranged in the first sub-chamber 213, the first fan 250 is arranged in the second sub-chamber 214, the air inlet duct 310 is connected to the second sub-chamber 214, the return air duct 320 is connected to the first sub-chamber 213, and a fourth through hole 271 is arranged at the third partition 270 so that the wind flowing into the first sub-chamber 213 from the return air duct 320 passes through the evaporator 220 for heat exchange and then flows to the second sub-chamber 214 from the fourth through hole 271, and then the first fan 250 blows the gas into the air inlet duct 310.

[0155] Specifically, in this embodiment, the first accommodating chamber 211 is divided into a first sub-chamber 213 and a second sub-chamber 214 by a third partition plate 270, so that the inlet of the air inlet duct 310 is connected to the second sub-chamber 214, while the outlet of the return air duct 320 is connected to the first sub-chamber 213, thereby separating the outgoing gas from the return gas, preventing the gas from flowing into the air inlet duct 310 without heat exchange, thereby affecting the outlet air temperature.

[0156] In addition, in this embodiment, a fourth through hole 271 is provided at the third partition plate 270, and the first fan 250 may be a centrifugal fan. The air inlet of the centrifugal fan is provided at the fourth through hole 271, and the air outlet 510 of the centrifugal fan may be directly connected to the inlet of the air inlet duct 310, so as to directly blow the gas in the first sub-cavity 213 into the air inlet duct 310.

[0157] More specifically, a fresh air inlet (not shown in the figure) is provided at the side wall of the first accommodating cavity 211 of the present embodiment, and a fresh air valve (not shown in the figure) is provided at the fresh air inlet, so that when the fresh air valve is opened, the first fan 250 blows part of the gas flowing from the first sub-cavity 213 into the second sub-cavity 214 and part of the fresh air entering through the fresh air inlet into the air inlet duct 310 together.

[0158] Specifically, in this embodiment, a fresh air inlet is arranged on the side wall of the first accommodating cavity 211. When the centrifugal fan blows the gas in the first sub-cavity 213 into the air inlet duct 310, due to the effect of negative pressure, the outside air will enter the second sub-cavity 214 through the fresh air inlet, and then be blown into the air inlet duct 310 through the centrifugal fan.

[0159] Specifically, a fresh air valve is provided at the fresh air inlet. When the temperature difference between indoor and outdoor is not large, the fresh air valve can be opened so that the fresh air and the gas in the first sub-cavity 213 are blown into the air inlet duct 310 together and then enter the target space 400. When the temperature difference between indoor and outdoor is large, the fresh air valve can be closed, and only the gas in the first sub-cavity 213 is blown into the target space 400.

[0160] Specifically, the fresh air inlet and the fresh air valve of this embodiment can be arranged on the side wall of the first sub-cavity 213 or on the side wall of the second sub-cavity 214. Preferably, the fresh air inlet and the fresh air valve are arranged on the side wall of the first sub-cavity 213, so that the fresh air can follow the gas flowing into the return air duct 320 to pass through the evaporator 220 for heat exchange and then be blown into the air inlet duct 310 by the centrifugal fan.

[0161] As a specific embodiment of the present invention, the second accommodating chamber 212 of this embodiment may further include a fourth partition 280, which divides the second accommodating chamber 212 into a third sub-chamber 215 and a fourth sub-chamber 216. The evaporator 220 is located in the third sub-chamber 215, and the compressor 240 is located in the fourth sub-chamber 216. The third sub-chamber 215 may further include a second motor (not shown in the figure) and a second fan 290, and the second motor drives the second fan 290 to rotate to dissipate heat for the condenser 230. The second motor drives the second fan 290 to rotate, and the second fan 290 takes away the heat from the condenser 230 during the rotation process to prevent the temperature of the condenser 230 from being too high.

[0162] As a specific embodiment of the present invention, at least one side wall of the third sub-cavity 215 of this embodiment is provided with an air outlet 217, and a grille 218 is provided at the air outlet 217. The condenser 230 is provided around the side wall of the third sub-cavity 215 where no air outlet is provided. The grille 218 of this specific embodiment can prevent external dust from entering the second accommodating cavity 212 on the one hand, and can also protect the outside world from causing harm to outsiders by the fan on the other hand.

[0163] Specifically, the second fan 290 of this embodiment may be an axial flow fan.

[0164] As a specific embodiment of the present invention, the air volume of the air supply duct 300 of the hole in this embodiment is 650m 3 / h~11000m 3 / h. For example, the air volume can be 650m 3 / h、700m 3 / h、750m 3 / h、800m 3 / h、900m 3 / h、1000m 3 / h or 1100m 3 / h, etc.

[0165] Specifically, when the fresh air valve of this embodiment is not opened, the air circulation is completely internal, and the wall section 350 of the air inlet duct is limited to a diameter of 160 mm, the air volume of this embodiment can reach 650 m 3 / h~700m 3 When the fresh air valve of this embodiment is opened, the internal circulation is combined with the external fresh air, and the air volume of the air inlet duct of this embodiment can reach 1100m 3 Specifically, the air intake volume is related to the diameter of the air supply duct 300 on the one hand, and the power of the centrifugal fan on the other hand. Of course, the size of the fresh air opening will also have a certain impact on the air intake volume.

[0166] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention.
