[0038] Reference below Figure 1-Figure 10 An integrated air conditioner 100 according to an embodiment of the present invention is described.

[0039] Reference Figure 1 , Figure 2 and Figure 3The integrated air conditioner 100 according to the embodiment of the present invention comprises a housing 1 and a compressor 2, a first heat exchanger 3 and a second heat exchanger 4 arranged in the housing 1. The first heat exchanger 3 and the second heat exchanger 4 are both connected to the compressor 2, and one of them serves as a condenser and the other as an evaporator. When the integrated air conditioner 100 is working, the compressor 2 compresses the refrigerant and sends the refrigerant to the condenser, and then throttles, and then the refrigerant passes through the evaporator to absorb heat in the air, and then returns to the compressor 2 to continue compression, and continues the cycle.

[0040] The integrated air conditioner 100 also includes a supply fan 5 and an exhaust fan 6 arranged in the outer shell 1. The supply fan 5 is used to induce the airflow to exchange heat with the first heat exchanger 3 and supply air to the indoor side, and the exhaust fan 6 is used to induce the airflow to exchange heat with the second heat exchanger 4 and exhaust air to the outdoor side.

[0041] It should be noted that the integrated air conditioner 100 can have only a cooling mode, or a cooling mode and a heating mode at the same time. In the cooling mode, the first heat exchanger 3 serves as an evaporator, and the second evaporator serves as a condenser. When the air supply fan 5 is working, it causes the airflow to exchange heat with the evaporator and the heat is absorbed by the evaporator, so that the air supply fan 5 delivers cold air to the room; in the heating mode, the first heat exchanger 3 serves as a condenser, and the second heat exchanger 4 serves as an evaporator. When the air supply fan 5 is working, it causes the airflow to exchange heat with the condenser and takes away the heat on the condenser, so that the air supply fan 5 delivers hot air to the room.

[0042] In the cooling mode, the second heat exchanger 4 is a condenser, and the condenser continuously generates heat that needs to be discharged to the outside by the exhaust fan 6. Therefore, the motor of the exhaust fan 6 is affected by the heat radiation generated by the condenser to affect the heat dissipation. The housing 1 is also provided with an electric control component 7. The function of the electric control component 7 is not limited. For example, it can be used to control the operation of components such as the compressor 2, the first heat exchanger 3, the second heat exchanger 4, the air supply fan 5, and the exhaust fan 6. When the integrated air conditioner 100 is working, the components in the electric control component 7 will continue to generate heat and generate high temperature. If the heat dissipation is not timely, the components in the electric control component 7 will be damaged.

[0043] That is to say, both the motor and the electronic control component 7 of the exhaust fan 6 have the need to improve the heat dissipation efficiency. Therefore, in the embodiment of the present invention, at least one of the motor and the electronic control component 7 of the exhaust fan 6 is a component P to be cooled. The integrated air conditioner 100 also includes a heat dissipation duct component 8, which cooperates with the component P to be cooled to form a heat dissipation duct between the component P to be cooled (for example, the first heat dissipation duct 811 and the second heat dissipation duct 821 described later, etc.), the inlet of the heat dissipation duct is connected to the outside of the outer casing 1, and the outlet of the heat dissipation duct is connected to the air inlet of the exhaust fan 6.

[0044] Reference Figure 3 and Figure 6According to the integrated air conditioner 100 of the embodiment of the present invention, the negative pressure area 61 generated by the exhaust fan 6 is used, and the heat dissipation duct is connected between the negative pressure area 61 and the external environment of the housing 1, so that the low-temperature gas in the external environment (i.e., the gas with a lower temperature than the heat dissipation component P) can be sucked into the negative pressure area 61 through the heat dissipation duct. Because the heat dissipation duct is formed by the heat dissipation duct member 8 and the heat dissipation component P, the low-temperature gas can take away the heat generated by the heat dissipation component P when passing through the heat dissipation duct, so as to achieve the purpose of continuously dissipating the heat for the heat dissipation component P, and prevent the heat dissipation component P from being damaged due to the temperature exceeding the normal working value, causing the whole machine to fail. The present invention realizes the heat dissipation of the motor and / or the electronic control component 7 of the exhaust fan 6 through the negative pressure area 61 generated by the exhaust fan 6, without the need to set up an additional heat exhaust fan, simplifies the structure of the integrated air conditioner 100, reduces the volume and cost of the integrated air conditioner 100, and is conducive to the embedded installation of the integrated air conditioner 100 (of course, the integrated air conditioner 100 of the embodiment of the present invention can also be installed in a non-embedded external manner). In addition, the heat exhaust fan is prevented from occupying the internal space of the outer shell 1 , which is beneficial to the air flow inside the outer shell 1 and further beneficial to the heat dissipation of the internal structural parts of the outer shell 1 .

[0045] It should be noted that in the embodiments of the present invention, at least one of the motor of the exhaust fan 6 and the electronic control component 7 is a component P to be dissipated. That is to say, in some embodiments, the motor of the exhaust fan 6 is a component P to be dissipated so as to improve the heat dissipation efficiency of the motor of the exhaust fan 6; in other embodiments, the electronic control component 7 is a component P to be dissipated so as to improve the heat dissipation efficiency of the electronic control component 7; in still other embodiments, both the motor and the electronic control component 7 of the exhaust fan 6 are components P to be dissipated so as to improve the heat dissipation efficiency of the motor and the electronic control component 7 of the exhaust fan 6.

[0046] In some specific embodiments, the housing 1 has a first air duct and a second air duct that are isolated from each other, the first heat exchanger 3 is arranged in the first air duct, the second heat exchanger 4 is arranged in the second air duct, the air inlet of the air supply fan 5 is connected to the first air duct, and the air inlet of the exhaust fan 6 is connected to the second air duct. When the integrated air conditioner 100 is working, the air supply fan 5 transports the air in the first air duct that has been heat-exchanged with the first heat exchanger 3 to the room, and the exhaust fan 6 transports the air in the second air duct that has been heat-exchanged with the second heat exchanger 4 to the outside. At this time, the outlet of the heat dissipation air duct can be connected to the second air duct, so that under the action of the exhaust fan 6, the inlet of the heat dissipation air duct can inhale low-temperature gas from the external environment.

[0047] Reference Figure 2 , Figure 3 and Figure 4In some embodiments, the exhaust fan 6 includes a first volute 62 and a first wind wheel 63 disposed in the first volute 62. The motor of the exhaust fan 6 is a first motor 64. At least part of the first motor 64 is located outside the first volute 62 and is connected to the first wind wheel 63 through a first drive shaft 65.

[0048] At least part of the first motor 64 is located outside the first volute 62 so that the first motor 64 can contact the air outside the first volute 62 for heat dissipation. When the exhaust fan 6 is working, the first motor 64 drives the first wind wheel 63 to rotate through the first drive shaft 65 to induce airflow to exchange heat with the second heat exchanger 4.

[0049] The heat dissipation duct component 8 includes a motor cover 81, at least part of which is located outside the first volute 62. The motor cover 81 covers the first motor 64 and forms a first heat dissipation duct 811 between the motor cover 81 and the first motor 64. The inlet of the first heat dissipation duct 811 is connected to the outside of the outer shell 1, and the outlet of the first heat dissipation duct 811 is connected to the inside of the first volute 62.

[0050] Through the above technical solution, on the one hand, the motor cover 81 can protect the first motor 64 to prevent other structural parts from interfering with the first motor 64. On the other hand, the motor cover 81 can form a first heat dissipation duct 811 between the first motor 64 and the motor cover 81. When the exhaust fan 6 is working, the first motor 64 drives the first wind wheel 63 to rotate, so that a negative pressure area 61 is generated in the first volute 62, so that the air outside the outer casing 1 can enter the first volute 62 through the first heat dissipation duct 811. When the air passes through the first heat dissipation duct 811, it continuously takes away the heat from the first motor 64, thereby achieving the purpose of continuously dissipating heat for the first motor 64 and preventing the first motor 64 from being damaged due to the temperature exceeding the normal working value.

[0051] In some embodiments, the peripheral sides of the first motor 64 are spaced apart from the motor cover 81 to form a first heat dissipation duct 811 .

[0052] Through the above technical solution, the surrounding sides of the first motor 64 are spaced apart from the motor cover 81, thereby increasing the contact area between the first motor 64 and the air. When the exhaust fan 6 works so that the air outside the housing 1 passes through the first heat dissipation duct 811, the air flows around the surface of the first motor 64 under the guidance of the motor cover 81, and forms a low-temperature wind film around the first motor 64, thereby continuously and evenly cooling the first motor 64, and further improving the heat dissipation efficiency of the first motor 64.

[0053] Reference Figure 3 , Figure 4 and Figure 5In some further embodiments, the first volute 62 includes a first volute portion 621 and a second volute portion 622 arranged in sequence along the axial direction of the first wind wheel 63, and the motor cover 81 is arranged on a side of the first volute portion 621 away from the second volute portion 622, and the motor cover 81 is integrally formed with the first volute portion 621.

[0054] Through the above technical scheme, the first volute 62 includes a first volute portion 621 and a second volute portion 622 arranged in sequence along the axial direction of the first wind wheel 63, that is, the first volute 62 is assembled from the first volute portion 621 and the second volute portion 622, which is beneficial to the assembly of the exhaust fan 6 and improves the assembly efficiency of the integrated air conditioner 100; the motor cover 81 and the first volute portion 621 are integrally formed, which on the one hand reduces the production cost of the motor cover 81, and on the other hand improves the connection strength between the motor cover 81 and the first volute portion 621, thereby enhancing the stability of the motor cover 81.

[0055] Reference Figure 3 , Figure 4 and Figure 5 In some embodiments, the housing 1 is provided with a first installation opening 13 at a position corresponding to the motor cover 81, and one end of the motor cover 81 away from the first volute 62 extends to the housing 1, and one end of the motor cover 81 away from the first volute 62 is formed to be open facing the first installation opening 13 to form an entrance to the first heat dissipation duct 811. When the exhaust fan 6 is working, a negative pressure area 61 is generated in the first volute 62, so that the air outside the housing 1 can enter the first heat dissipation duct 811 through the first installation opening 13.

[0056] Through the above technical solution, the motor cover 81 directly extends to the outer casing 1, and the open opening of the motor cover 81 (that is, the entrance of the first heat dissipation duct 811) is set toward the first mounting port 13. In the embodiment of the present invention, there is no need to set other structural parts to connect the first mounting port 13 and the first heat dissipation duct 811, thereby effectively reducing the cost of the integrated air conditioner 100.

[0057] Reference Figure 3 , Figure 4 and Figure 5 In some further embodiments, the integrated air conditioner 100 includes a motor pressure plate 14 arranged at the first mounting port 13, and a ventilation channel 143 is defined between the motor pressure plate 14 and the outer casing 1 or the motor pressure plate 14 alone, and the entrance of the first heat dissipation duct 811 is connected to the outside of the outer casing 1 through the ventilation channel 143.

[0058] In the above technical solution, by arranging the motor pressing plate 14 at the first mounting opening 13, the movement of the first motor 64 is restricted, thereby enhancing the stability of the first motor 64. A ventilation channel 143 is defined between the motor pressing plate 14 and the housing 1 or by the motor pressing plate 14 alone, so as to ensure that the air outside the housing 1 can enter the first heat dissipation duct 811 through the ventilation channel 143.

[0059] Reference Figure 3 , Figure 4 and Figure 5 In some specific embodiments, the motor pressure plate 14 includes a pressure plate portion 141 and a mounting portion 142. The pressure plate portion 141 is used to stop against one end of the first motor 64 away from the first volute 62 to limit the movement of the first motor 64. The mounting portion 142 is connected to the pressure plate portion 141 and extends toward the radial outside of the first mounting opening 13. The mounting portion 142 is suitable for being fixed to the housing 1 by fasteners. There are multiple mounting portions 142, and the multiple mounting portions 142 are arranged at intervals around the pressure plate portion 141. A ventilation channel 143 is defined between two adjacent mounting portions 142, the pressure plate portion 141 and the inner wall of the first mounting opening 13. In some embodiments, there are three mounting portions 142, that is, three ventilation channels 143 are defined between the motor pressure plate 14 and the housing 1. In other embodiments, the mounting portions 142 can also be four, five or other numbers, that is, the ventilation channels 143 can be four, five or other numbers. It is understandable that other situations are also possible, as long as a ventilation channel 143 is defined between the motor pressure plate 14 and the housing 1.

[0060] In some other specific embodiments, the motor pressure plate 14 is constructed as a plate-like structure that blocks the first installation opening 13 , and a through hole penetrating the motor pressure plate 14 is provided in the thickness direction of the motor pressure plate 14 to form a ventilation channel 143 .

[0061] Reference Figure 3 , Figure 4 and Figure 5 In some embodiments, at least one air outlet 812 is formed on a side surface of the motor cover 81 facing the first volute 62 to form an outlet of the first heat dissipation duct 811. When the exhaust fan 6 is working, the air outside the housing 1 enters the first heat dissipation duct 811 and then enters the first volute 62 through the air outlet 812.

[0062] Reference Figure 3 , Figure 4 and Figure 5In some specific embodiments, a mounting groove 813 extending toward the inside of the first volute 62 is provided on the side of the motor cover 81 facing the first volute 62, and a through hole for the first drive shaft 65 to pass through is provided on the inner wall of the mounting groove 813. A plurality of air outlet holes 812 are formed on the surface of the side of the motor cover 81 facing the first volute 62, and the plurality of air outlet holes 812 are arranged at intervals around the mounting groove 813.

[0063] At least a portion of the first motor 64 is disposed in the mounting groove 813 , and a side of the first motor 64 close to the first volute 62 abuts against an inner wall of the mounting groove 813 , and a side of the first motor 64 away from the first volute 62 is limited by the motor pressure plate 14 , thereby ensuring the stability of the first motor 64 .

[0064] Reference Figure 2 , Figure 6 and Fig. 9 In some embodiments, the electric control component 7 includes an electric control box 71 and a circuit board 72 disposed in the electric control box 71, and the heat dissipation duct member 8 includes a duct cover 82, which is disposed outside the electric control box 71 and forms a second heat dissipation duct 821 with the electric control box 71, and the duct cover 82 includes an inlet 822 and an outlet 823, the inlet 822 participates in defining or independently defines the inlet of the second heat dissipation duct 821, and the outlet 823 participates in defining or independently defines the outlet of the second heat dissipation duct 821. The inlet of the second heat dissipation duct 821 is communicated with the outside of the housing 1, and the outlet of the second heat dissipation duct 821 is communicated with the air inlet of the exhaust fan 6.

[0065] It should be noted that the scheme in which the inlet portion 822 participates in defining or independently defines the inlet of the second heat dissipation air duct 821 is not limited. For example, the inlet portion 822 and the housing 1 may cooperate to jointly define the inlet of the second heat dissipation air duct 821, or the inlet portion 822 extends to the outside of the housing 1, and the inlet of the second heat dissipation air duct 821 is formed on the portion of the inlet portion 822 located on the outside of the housing 1. The scheme in which the outlet portion 823 participates in defining or independently defines the outlet of the second heat dissipation air duct 821 is not limited. For example, the outlet portion 823 and the electric control box 71 may cooperate to jointly define the outlet of the second heat dissipation air duct 821, or the outlet portion 823 may be provided with a through hole to form the outlet of the second heat dissipation air duct 821, etc.

[0066] Through the above technical solution, on the one hand, the air duct cover 82 can protect the electric control box 71 and reduce the collision between other structural parts and the electric control box 71. On the other hand, the air duct cover 82 can form a second heat dissipation duct 821 with the electric control box 71. When the exhaust fan 6 is working, the first motor 64 drives the first wind wheel 63 to rotate, so that negative pressure is generated at the air inlet of the first volute 62, so that the air outside the outer shell 1 can enter the first volute 62 through the second heat dissipation duct 821. When the air passes through the second heat dissipation duct 821, it continuously takes away the heat from the electric control box 71, so as to achieve the purpose of continuously dissipating heat for the electric control component 7 and prevent the electric control component 7 from being damaged due to the temperature exceeding the normal working value.

[0067] Reference Figure 6 , Figure 7 and Figure 8 In some embodiments, a side wall of the electric control box 71 facing the air duct cover 82 has a first protruding portion 71121 and a first avoidance opening 71122, the first protruding portion 71121 protrudes toward the air duct cover 82, the electric control component 7 includes a heat sink 721 and a heating element 722 disposed on the circuit board 72, the heating element 722 is disposed corresponding to the first protruding portion 71121, and the heat sink 721 is exposed by the first avoidance opening 71122. The type of the heating element 722 is not limited, for example, it can be a component with large heat generation, such as a capacitor or an inductor.

[0068] Through the above technical solution, the heating element 722 is arranged corresponding to the first outer protrusion 71121, and the first outer protrusion 71121 protrudes toward the direction of the air duct cover 82, thereby increasing the heating area of ​​the side wall of the electric control box 71 that is heated by the heat radiation of the heating element 722, and also increasing the contact area between the side wall of the electric control box 71 and the air, so that the heat of the heating element 722 is dissipated out of the electric control box 71 as much as possible, and is taken away by the air flowing through the second heat dissipation air duct 821, thereby improving the heat dissipation efficiency of the electric control component 7. The electric control component 7 also includes a heat sink 721 connected to the circuit board 72, and the heat sink 721 can dissipate heat from the circuit board 72, and the heat sink 721 is exposed to the second heat dissipation air duct 821 through the first avoidance opening 71122, so that the heat on the heat sink 721 can be taken away by the air flowing through the second heat dissipation air duct 821, further improving the heat dissipation efficiency of the electric control component 7.

[0069] Reference Figure 6 , Figure 7 and Figure 8 In some further embodiments, in the airflow direction from the inlet to the outlet of the second heat dissipation duct 821 , the heat sink 721 is located downstream of the heat generating element 722 .

[0070] The electric control component 7 dissipates heat through the heat sink 721 on the one hand, and dissipates heat through the heating element 722 on the other hand. The heat dissipation area and heat dissipation amount of the heat sink 721 are greater than those of the heating element 722. Therefore, through the above technical solution, when the low-temperature external air enters the second heat dissipation duct 821, the low-temperature air flow first flows through the first convex portion 71121 corresponding to the heating element 722. The heat released by the first convex portion 71121 is relatively low, and the air after passing through the first convex portion 71121 is relatively low in temperature relative to the heat sink 721 area. There is still a large temperature difference; the air then flows through the heat sink 721 to dissipate heat from the heat sink 721, which can ensure the effectiveness of heat dissipation from the heat sink 721. Finally, the air enters the exhaust fan 6 through the outlet of the second heat dissipation duct 821. Because the exhaust fan 6 works, it can continuously draw the low-temperature air outside the housing 1 into the second heat dissipation duct 821, so that it flows through the first outer protrusion 71121 according to the above process to first take away the heat in this area, and then passes through the heat sink 721 area to continuously take away the heat on the heat sink 721. This allows the airflow to continuously and fully take away the heat of the electronic control component 7, so that the electronic control component 7 can operate within a suitable temperature range, and avoid damage to the electronic control component 7 due to excessive temperature.

[0071] Reference Figure 6 , Figure 7 and Figure 8 In some specific embodiments, the inlet 822 is located at the lower part of the air duct cover 82, the outlet 823 is located at the upper part of the air duct cover 82, the heat sink 721 and the heating element 722 are both higher than the inlet 822 and lower than the outlet 823, and the heat sink 721 is higher than the heating element 722.

[0072] Through the above technical solution, the inlet 822 is located at the lower part of the air duct cover 82, and the outlet 823 is located at the upper part of the air duct cover 82, so that the air flows from bottom to top in the second heat dissipation air duct 821, and the heat sink 721 and the heating element 722 are located between the inlet 822 and the outlet 823, and the heat sink 721 is higher than the heating element 722, so that the air flow first flows through the first protrusion 71121 corresponding to the heating element 722, and then flows through the heat sink 721. It also conforms to the physical flow direction of hot air and avoids the problem of hot air backflow.

[0073] Reference Figure 6 , Figure 8 and Fig. 9In some embodiments, the electric control box 71 includes a first box portion 711 and a second box portion 712, the circuit board 72 is arranged in the installation cavity formed between the first box portion 711 and the second box portion 712, the air duct cover 82 is arranged on the side of the first box portion 711 away from the second box portion 712, the first box portion 711 includes an inner shell 7111 and an outer shell 7112, the first outer protrusion 71121 is formed on the outer shell 7112, the inner shell 7111 has a second avoidance opening 71111, at least part of the second avoidance opening 71111 is arranged corresponding to the first outer protrusion 71121, and a part of the heating element 722 extends out of the second avoidance opening 71111 and is accommodated in the first outer protrusion 71121. The inner shell 7111 and the outer shell 7112 are both provided with a first avoidance opening 71122 for the heat sink 721 to pass through.

[0074] That is to say, the heating element 722 is installed in the installation cavity between the inner shell 7111 and the second box part 712, and the heating element 722 partially extends out of the second avoidance opening 71111 and is located in the first outer protrusion 71121, which reduces the distance between the heating element 722 and the first outer protrusion 71121 and facilitates the heat dissipation of the heating element 722.

[0075] In some specific embodiments, the inner shell 7111 and the second box part 712 are both made of plastic materials, which reduces the cost of the electric control box 71. The outer shell 7112 is made of metal materials, which, on the one hand, enhances the overall structural strength of the electric control box 71, and on the other hand, because metal has a high heat dissipation efficiency, improves the heat dissipation efficiency of the heating element 722. The entire outer shell 7112 can be used for heat dissipation of the heating element 722. The heating element 722 transfers heat to the outer shell 7112 through air, and then the air flowing in the second heat dissipation duct 821 takes away the heat on the outer shell 7112.

[0076] In some embodiments, the distance between the heating element 722 and the inner wall of the first outer protrusion 71121 is greater than 10 mm, so that the distance between the heating element 722 and the outer shell 7112 meets the designed electrical safety distance.

[0077] In some specific embodiments, the distance between the heating element 722 and the inner wall of the first outer protrusion 71121 is within the range of 10 mm to 20 mm, so that the distance between the heating element 722 and the outer shell 7112 is achieved at the minimum distance under the premise of ensuring the designed electrical safety distance, so that the heat radiated from the heating element 722 to the outer shell 7112 can be as much as possible.

[0078] The second heat dissipation duct 821 of the present invention is designed with a gradient heat dissipation layout. The air in the environment outside the outer shell 1 first flows through the first outer protrusion 71121 corresponding to the heating element 722. At the same time, there is a maximum heat radiation surface between the heating element 722 and the outer shell 7112, so that the airflow can take away more heat. The air flowing through the first outer protrusion 71121 then passes through the heat sink 721 to take away the concentrated heat dissipation heat with a higher temperature, and fully utilizes the air flowing through the electrical control box 71 to ensure that all heat-releasing components can reach a state where the temperature difference is high enough, thereby achieving the optimal air-cooling heat dissipation effect.

[0079] Reference Figure 6 , Figure 7 and Figure 8 In some embodiments, the air duct cover 82 is provided with a second outer protrusion 824 , at least a portion of the second outer protrusion 824 is arranged corresponding to the first outer protrusion 71121 , and the second outer protrusion 824 protrudes in a direction away from the electric control box 71 .

[0080] In the above technical solution, a second outer protrusion 824 corresponding to the first outer protrusion 71121 is provided on the air duct cover 82 to ensure the cross-sectional area of ​​the second heat dissipation duct 821 at the first outer protrusion 71121, thereby reducing the obstruction of the first outer protrusion 71121 to the air flow and ensuring the stability of the air flow in the second heat dissipation duct 821.

[0081] Reference Figure 6 , Fig. 9 and Fig.10 In some embodiments, the outer shell 1 has a second mounting opening 15 , and the second outer protrusion 824 extends out of the second mounting opening 15 . The integrated air conditioner 100 also includes a shell cover plate 9 , which is located outside the outer shell 1 and covers the second mounting opening 15 .

[0082] In the above technical solution, the second mounting opening 15 is provided on the housing 1, so that the second outer protrusion 824 can pass through the housing 1 through the second mounting opening 15, thereby preventing the second outer protrusion 824 from interfering with the housing 1. The housing 1 is also provided with a shell cover plate 9 covering the second mounting opening 15. On the one hand, the shell cover plate 9 can protect the second outer protrusion 824, thereby preventing the second outer protrusion 824 from colliding with external objects, thereby ensuring the stability of the second heat dissipation duct 821; on the other hand, the second mounting opening 15 can be shielded, thereby improving the appearance of the integrated air conditioner 100.

[0083] Reference Figure 6 , Fig. 9 and Fig.10 In some specific embodiments, the shell cover plate 9 has a third avoidance opening 91 , and the inlet portion 822 extends to the third avoidance opening 91 , so that the inlet of the second heat dissipation duct 821 is connected to the outside of the shell 1 when the third avoidance opening 91 is located.

[0084] In some embodiments, the integrated air conditioner 100 is suitable for embedded installation, for example, in a relatively closed space such as in a suspended ceiling, under an operating table, or embedded in a cabinet. By adopting the heat dissipation solution proposed in the invention, it is helpful to solve the problem that the integrated air conditioner 100 is difficult to dissipate heat in a relatively closed space, thereby affecting the working reliability.

The second heat exchanger 4 and the electric control box 71 are located on both sides of the compressor 2 in the width direction of the housing 1. As a result, the structure of the integrated air conditioner 100 is relatively compact, occupies less space, is conducive to embedded installation, and is conducive to isolating the cold and hot air ducts from each other, reducing the heat radiation effect of the condenser on the electric control component 7.

The exhaust fan 6 may include a first wind wheel 63 and a first motor 64 for driving the first wind wheel 63 to rotate, and the first motor 64 is arranged on the top of the first wind wheel 63, which is convenient for installation, wiring, and space saving.

The water receiving groove is arranged below the first heat exchanger 3 and the second heat exchanger 4 to collect condensed water dripping from the first heat exchanger 3 or the second heat exchanger 4.

[0089] In some specific embodiments, the bottom of the water receiving tank has an inclined angle for guiding the condensed water to flow under the second heat exchanger 4. When the integrated air conditioner 100 is in cooling mode, the second heat exchanger 4 is a condenser. The bottom of the water receiving tank in the embodiment of the present invention is provided with an inclined angle, so that the condensed water in the water receiving tank can be gathered under the second heat exchanger 4, which is beneficial to the heat dissipation of the condenser.
