Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an integrated air conditioner. Background Technology

[0002] In related technologies, integrated air conditioners consist of two parts: an indoor module and an outdoor module. Both the indoor and outdoor modules include multiple components, such as heat exchange components and fan components. The integrated air conditioner also has an electrical control box component to control the operation of the fan components, etc. During the operation of the air conditioner, the electrical control module of the control box component generates a large amount of heat, requiring heat dissipation. However, due to the unsatisfactory heat dissipation effect of the control box component, it operates at high temperatures, affecting the normal operation of the integrated air conditioner. Therefore, improvements are needed. Utility Model Content

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide an integrated air conditioner that, by setting a heat dissipation duct upstream of the indoor fan and positioning the duct on the side of the circuit board near the first receiving cavity, allows airflow from the external space to continuously enter the heat dissipation duct under the drive of the indoor fan, thus achieving heat dissipation for the electrical control box. Furthermore, the airflow temperature in the external space of the integrated air conditioner is lower than the airflow temperature inside, which is beneficial for improving the heat dissipation efficiency of the electrical control box components and achieving continuous heat dissipation. In addition, this also helps to shorten the overall flow path of the airflow from the external space towards the first receiving cavity via the heat dissipation duct, thereby further improving the heat dissipation effect on the electrical control box.

[0004] An integrated air conditioner according to an embodiment of the present invention includes: a chassis component; an indoor module and an outdoor module, both disposed on the chassis component and arranged along a first direction; the indoor module includes a first housing and an indoor air supply assembly, a first receiving cavity is defined between the first housing and the chassis component, the indoor air supply assembly is disposed in the first receiving cavity and includes an indoor fan; the outdoor module includes a second housing and an outdoor exhaust assembly, a second receiving cavity is defined between the second housing and the chassis component, the outdoor exhaust assembly is disposed in the second receiving cavity; an electrical control box, installed on the outside of the indoor module, the electrical control box including a box body and a circuit board disposed within the box body; a heat dissipation duct, located on the side of the circuit board near the first receiving cavity, the heat dissipation duct connecting the external space of the integrated air conditioner and the first receiving cavity, the heat dissipation duct being located upstream of the indoor fan, and the airflow in the external space of the integrated air conditioner being adapted to flow through the heat dissipation duct under the drive of the indoor fan to dissipate heat from the electrical control box.

[0005] According to the embodiment of the present invention, the integrated air conditioner has a heat dissipation duct located upstream of the indoor fan. During the operation of the integrated air conditioner, the operation of the indoor fan located in the first accommodating cavity will create a pressure difference between the first accommodating cavity and the external space of the integrated air conditioner. This allows the airflow from the external space to continuously enter the heat dissipation duct under the drive of the indoor fan, thereby dissipating heat from the electrical control box. Furthermore, the airflow temperature in the external space of the integrated air conditioner is lower than the airflow temperature inside, which is beneficial for improving the heat dissipation efficiency of the electrical control box components and achieving a continuous heat dissipation effect.

[0006] Furthermore, by positioning the heat dissipation duct on the side of the circuit board closer to the first receiving cavity, the overall airflow path of the integrated air conditioner's external space towards the first receiving cavity is shortened, reducing flow resistance and thus further improving the heat dissipation effect on the control box.

[0047] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0048] The following is for reference. Figures 1-7 Description of an integrated air conditioner 100100 according to an embodiment of the present utility model.

[0049] refer to Figures 1-7 According to an embodiment of the present utility model, the integrated air conditioner 100 includes: a chassis component 20, an indoor module 10, an outdoor module, an electrical control box 4, and a heat dissipation duct 5. The indoor module 10 and the outdoor module are both disposed on the chassis component 20, and the indoor module 10 and the outdoor module are arranged along a first direction (refer to the direction e1 in the figure). The electrical control box 4 is disposed on the outside of the indoor module 10, and the heat dissipation duct 5 is located between the electrical control box 4 and the indoor module 10.

[0050] Optionally, the electrical control box 4 is located at one end of the indoor module 10 along the first direction; alternatively, the electrical control box 4 is located at one end of the indoor module 10 along the second direction.

[0051] The indoor module 10 includes a first housing 1 and an indoor air supply assembly 2. A first receiving cavity 3 is defined between the first housing 1 and the chassis component 20. The indoor air supply assembly 2 is disposed in the first receiving cavity 3 and includes an indoor fan 21. The outdoor module includes a second housing and an outdoor exhaust assembly. A second receiving cavity is defined between the second housing and the chassis component 20. The outdoor exhaust assembly is disposed in the second receiving cavity. By placing the indoor air supply assembly 2 in the first receiving cavity 3 and the outdoor exhaust assembly in the second receiving cavity, the spaces of the first receiving cavity 3 and the second receiving cavity can be fully utilized, making the internal structure of the integrated air conditioner 100 compact. Furthermore, by spaced the indoor air supply assembly 2 and the outdoor exhaust assembly in different cavities, the mutual interference between the indoor air supply assembly 2 and the outdoor exhaust assembly can be reduced.

[0052] Optionally, both the first housing 1 and the second housing are detachably connected to the chassis assembly.

[0053] Optionally, the indoor air supply assembly 2 includes an indoor fan 21 and an indoor heat exchanger 22, with the indoor heat exchanger 22 located upstream of the indoor fan 21. For example, the indoor heat exchanger 22 is an evaporator. Optionally, the indoor air supply assembly 2 also includes a condensate tray located on the bottom surface of the indoor heat exchanger 22, which is used to collect condensate generated on the indoor heat exchanger 22.

[0054] Optionally, the outdoor exhaust assembly includes an outdoor fan, an outdoor heat exchanger, and a compressor, with the outdoor heat exchanger located upstream of the outdoor fan; for example, the outdoor heat exchanger is a condenser.

[0055] The electrical control box 4 includes a box body 41 and a circuit board 42 disposed in the box body 41, and also includes components 43 disposed on the circuit board 42. The circuit board 42 is electrically connected to other components of the integrated air conditioner 100 for controlling the operation of these components.

[0056] The heat dissipation duct 5 is located on the side of the circuit board 42 near the first receiving cavity 3. The heat dissipation duct 5 connects the external space of the integrated air conditioner 100 and the first receiving cavity 3. The heat dissipation duct 5 is located upstream of the indoor fan 21. The airflow in the external space of the integrated air conditioner 100 is suitable to flow through the heat dissipation duct 5 under the drive of the indoor fan 21 to dissipate heat from the electrical control box 4.

[0057] Optionally, the heat dissipation duct 5 is directly connected to the external space of the integrated air conditioner 100 or indirectly connected to the external space of the integrated air conditioner 100.

[0058] During the operation of the integrated air conditioner 100, the operation of the indoor fan 21 creates a pressure difference between the external space of the integrated air conditioner 100 and the first receiving cavity 3. For example, the operation of the indoor fan 21 creates a negative pressure zone in the area upstream of the indoor fan 21 within the first receiving cavity 3, resulting in a pressure difference between the external space of the integrated air conditioner 100 and the negative pressure zone. This pressure difference causes the airflow from the external space to flow towards the heat dissipation duct 5 under the drive of the outdoor fan, dissipating heat from the electrical control box 4 as it flows through the heat dissipation duct 5. This airflow then flows towards the first receiving cavity 3 and is discharged from the indoor module 10 under the action of the fan. Since the heat dissipation duct 5 is located on the side of the circuit board 42 closest to the first receiving cavity 3, it shortens the airflow path from the external space to the first receiving cavity 3, further improving the heat dissipation effect on the electrical control box 4.

[0059] Optionally, the electrical control box 4 assembly includes an electrical control module and a heat sink 44. The heat sink 44 is disposed on the electrical control module. The electrical control module includes a circuit board 42 and components 43 disposed on the circuit board 42. During the operation of the integrated air conditioner 100, some of the heat generated by the electrical control module can be conducted to the heat sink 44, and the heat sink 44 is used to dissipate heat from the electrical control module.

[0060] Optionally, the electronic control box 4 assembly includes a radiator 44, at least a portion of which is located within the cooling duct 5. For example, a portion of the radiator 44 is located within the cooling duct 5; or the entire radiator 44 is located within the cooling duct 5. By positioning at least a portion of the radiator 44 within the cooling duct 5, heat is dissipated from the electronic control module. The heat generated by the electronic control module is conducted to the radiator 44. As the external airflow of the integrated air conditioner 100 flows through the cooling duct 5, it exchanges heat with the radiator 44, carrying away the heat from the radiator 44 and thus dissipating the heat generated by the electronic control module, thereby achieving heat dissipation for the electronic control module.

[0061] According to the embodiment of the present utility model, the integrated air conditioner 100 has a heat dissipation duct 5 located upstream of the indoor fan 21. During the operation of the integrated air conditioner 100, the operation of the indoor fan 21 located in the first receiving cavity 3 will create a pressure difference between the first receiving cavity 3 and the external space of the integrated air conditioner 100. This allows the airflow from the external space to continuously enter the heat dissipation duct 5 under the driving action of the indoor fan 21 to dissipate heat from the electrical control box 4. Furthermore, the airflow temperature in the external space of the integrated air conditioner 100 is lower than the airflow temperature inside, which is beneficial to improving the heat dissipation efficiency of the electrical control box 4 components and achieving a continuous heat dissipation effect.

[0062] Furthermore, by positioning the heat dissipation duct 5 on the side of the circuit board 42 closer to the first receiving cavity 3, the overall flow path of the airflow in the external space of the integrated air conditioner 100 towards the first receiving cavity 3 via the heat dissipation duct 5 is shortened, which helps reduce flow resistance and further improves the heat dissipation effect on the control box 4. These factors all help reduce or avoid situations where the components of the control box 4 operate at high temperatures, thereby preventing them from affecting the normal operation of the integrated air conditioner 100 and extending its service life.

[0063] refer to Figure 4 According to some embodiments of the present invention, the electrical control box 4 includes a heat sink 44, which is thermally connected to the components 43 on the circuit board 42, and at least a portion of the heat sink 44 is located within the heat dissipation duct 5.

[0064] Optionally, the circuit board 42 includes a first region and a second region, with different components 43 in the first and second regions. During the operation of the electronic control box 4, the heat generated by the components 43 in the first region is greater than that of the components 43 in the second region. The heat sink 44 is located in the first region and is thermally connected to the components 43 in the first region, so as to effectively dissipate heat from the first region where the electronic control module generates more heat, thereby effectively preventing the electronic control module from overheating locally.

[0065] For example, the components 43 located in the first area of ​​the circuit board 42 include rectifier bridges, IGBTs, etc.; for example, the components 43 located in the second area of ​​the circuit board 42 include common mode inductors, PFC inductors, capacitors, power supplies, etc.

[0066] At least a portion of the radiator 44 is located within the heat dissipation duct 5, which may include the following situations: for example, a portion of the radiator 44 is located within the heat dissipation duct 5; or, for another example, the entire radiator 44 is located within the heat dissipation duct 5.

[0067] Optionally, the radiator 44 is made of aluminum.

[0068] By setting up a radiator 44, during the operation of the electrical control box 4, the components 43 on the circuit board 42 will generate a large amount of heat. The radiator 44 exchanges heat with the components 43 on the circuit board 42 to dissipate heat. By placing at least a portion of the radiator 44 inside the heat dissipation duct 5, the airflow entering the external space of the integrated air conditioner 100 under the action of pressure difference can also exchange heat with the radiator 44 to dissipate heat from the radiator 44.

[0069] refer to Figures 1-4 According to some embodiments of this utility model, the control box 4 is located at one end of the indoor module 10 along the second direction (refer to direction e2 in the figure), the thickness direction of the circuit board 42 is consistent with the second direction, and the heat dissipation duct 5 is located on the side of the circuit board 42 along the second direction near the first receiving cavity 3. By placing the control box 4 at one end of the indoor module 10 along the second direction, the control box 4 makes full use of the space at one end of the indoor module 10 along the second direction, making the layout of the integrated air conditioner 100 reasonable and the structure compact.

[0070] refer to Figures 3-7 According to some optional embodiments of the present invention, the electrical control box 4 includes a heat sink 44, which is thermally connected to the components 43 on the circuit board 42. At least a portion of the heat sink 44 is located within the heat dissipation duct 5. The heat sink 44 includes a plurality of heat sink fins 441 arranged at intervals along a third direction (refer to direction e3 in the figure). The third direction, the second direction, and the first direction intersect each other in pairs, and a heat dissipation gap 442 is defined between two adjacent heat sink fins 441 for airflow.

[0071] For example, a portion of the radiator 44 is located within the heat dissipation duct 5; or the entire radiator 44 is located within the heat dissipation duct 5.

[0072] By defining a heat dissipation gap 442 between two adjacent heat sinks 441 arranged along a third direction of the radiator 44 for airflow passage, and extending the heat dissipation gap 442 along a first direction, the airflow direction in the first heat dissipation duct 5 is consistent with the extension direction of the heat dissipation gap 442, so that the airflow can flow smoothly through the radiator 44 and fully exchange heat with the multiple heat sinks 441.

[0073] Optionally, the radiator 44 is located near the airflow inlet of the heat dissipation duct 5 along the first direction, so that the airflow in the first heat dissipation duct 5 can flow through the radiator 44 to the maximum extent and fully exchange heat with the radiator 44, thereby improving the heat exchange efficiency and heat exchange effect.

[0074] refer to Figure 4 According to some embodiments of this utility model, at least a portion of the heat dissipation duct 5 is located within the housing 41. The housing 41 has an airflow inlet 411, which connects the heat dissipation duct 5 to the external space of the integrated air conditioner 100. The fact that at least a portion of the heat dissipation duct 5 is located within the housing 41 can include several scenarios: for example, a portion of the heat dissipation duct 5 is located within the housing 41; or, for example, the entire heat dissipation duct 5 is located within the housing 41. By ensuring that at least a portion of the heat dissipation duct 5 is located within the housing 41, and by providing the airflow inlet 411 connecting the heat dissipation duct 5 to the external space, the airflow inlet 411 facilitates the smooth flow of air from the external space into the heat dissipation duct 5 through the housing 41. This also improves the heat dissipation effect of the airflow within the heat dissipation duct 5 on the components within the housing 41.

[0075] Optionally, part of the heat dissipation duct 5 is located inside the housing 41, and another part of the heat dissipation duct 5 is located outside the housing 41 and between the housing 41 and the indoor module 10.

[0076] refer to Figures 1-4 According to some optional embodiments of the present invention, the indoor air supply assembly 2 includes an indoor heat exchanger 22, which is located on the outer periphery of the indoor fan 21. During the operation of the integrated air conditioner 100, the indoor fan 21 drives the external airflow of the indoor module 10 to enter the first receiving cavity 3 through the air inlet structure. When this airflow flows through the indoor heat exchanger 22, it exchanges heat with the indoor heat exchanger 22 to achieve cooling or heating of the airflow.

[0077] Part of the indoor heat exchanger 22 is located between the electrical control box 4 and the indoor fan 21, with the electrical control box 4 and the indoor heat exchanger 22 separated. Part of the heat dissipation duct 5 is located inside the housing 41, with another part of the heat dissipation duct 5 located between the electrical control box 4 and the indoor heat exchanger 22. For example, under the drive of the indoor fan 21, the airflow from the external space of the integrated air conditioner 100 first flows through part of the heat dissipation duct 5 inside the housing 41, then through part of the heat dissipation duct 5 between the electrical control box 4 and the indoor heat exchanger 22, and finally flows from the heat dissipation duct 5 through the indoor heat exchanger 22 to the first receiving cavity 3. By separating the electrical control box 4 from the indoor heat exchanger 22, the space of the heat dissipation duct 5 is increased, allowing more external airflow to enter the heat dissipation duct 5 to dissipate heat from the electrical control box 4. This also facilitates the smooth flow of airflow within the heat dissipation duct 5 towards the first receiving cavity 3, further enhancing the heat dissipation effect on the electrical control box 4.

[0078] refer to Figures 6-7 According to some optional embodiments of the present invention, the housing 41 includes a first housing 412 and a second housing 413 that are detachably connected. The first housing 412 is made of plastic, and the second housing 413 is made of metal. The circuit board 42 is located inside the first housing 412. A clearance opening 4121 is formed on the first housing 412 to avoid the heat sink 44. The clearance opening 4121 facilitates the exposure of the heat sink 44 so that the airflow can fully exchange heat with the heat sink 44, thereby improving the heat dissipation effect of the heat sink 44. The second housing 413 covers the outside of the first housing 412, and at least a portion of the heat sink 44 is exposed to the outside of the housing 41. An airflow inlet 411 is formed on the first housing 412.

[0079] At least a portion of the radiator 44 is exposed to the outside of the housing 41, which may include the following situations: for example, a portion of the radiator 44 is exposed to the outside of the housing 41; or, for example, the entire radiator 44 is exposed to the outside of the housing 41. For example, the portion of the radiator 44 exposed to the outside of the housing 41 is located within the heat dissipation duct 5 between the housing 41 and the indoor heat exchanger 22.

[0080] Optionally, the housing 41 also includes a third housing 414 and a fourth housing 415 that are detachably connected. The third housing 414 is made of plastic, and the fourth housing 415 is made of metal. The circuit board 42 is located inside the third housing 414, and the fourth housing 415 covers the outside of the third housing 414. The third housing 414 and the fourth housing 415 are connected to the side of the first housing 412 away from the indoor module 10.

[0081] For example, the third box 414 and the fourth box 415 are snapped together, and the circuit board 42 is snapped and fixed inside the third box 414.

[0082] refer to Figures 6-7According to some optional embodiments of this utility model, a grille structure is provided at the airflow inlet 411. By providing a grille structure at the airflow inlet 411, the grille structure helps to enhance the structural strength of the first box 412, and the grille structure will not obstruct the airflow into the heat dissipation duct 5; in addition, the grille structure can also separate the space inside the box 41 from the external space. For example, the indoor module 10 and the circuit board 42 are connected by a wire harness, and the grille structure separates the wire harness from the heat sink 44, and the grille structure provides protection for the wire harness to prevent the heat sink 441 of the heat sink 44 from scratching the wire harness, etc.

[0083] refer to Figures 6-7 According to some optional embodiments of this utility model, the grille structure is integrally formed with the first box 412. By making the grille structure integrally formed with the box 412, the connection and installation operations between the grille structure and the first box 412 can be eliminated, which is beneficial to improving the installation and production efficiency of the integrated air conditioner 100.

[0084] refer to Figure 7 According to some embodiments of the present invention, at least some of the components 43 on the circuit board 42 are located on the side of the circuit board 42 near the first receiving cavity 3.

[0085] For example, some components 43 on the circuit board 42 are located on the side of the circuit board 42 closer to the first receiving cavity 3; or, for another example, all components 43 on the circuit board 42 are located on the side of the circuit board 42 closer to the first receiving cavity 3.

[0086] By placing at least some of the components 43 of the circuit board 42 on the side of the circuit board 42 closer to the first receiving cavity 3, these components 43 can make full use of the space between the circuit board 42 and the indoor module 10. In this way, these components 43 are close to the heat dissipation duct 5, which is conducive to the airflow flowing through the heat dissipation duct 5 to better remove the heat generated by these components 43 during operation, thereby improving the heat dissipation effect on the electrical control box 4.

[0087] refer to Figures 2-5 According to some optional embodiments of the present invention, the indoor module 10 and the circuit board 42 are connected by a wire harness. At least a portion of the wire harness bypasses the outside of the control box 4 and is connected to the side of the circuit board 42 away from the first receiving cavity 3. The integrated air conditioner 100 also includes a protective cover assembly 6, which covers the outside of the control box 4. The protective cover assembly 6 and the control box 4 define a wiring space 7, or the protective cover assembly 6, the control box 4, and the indoor module 10 together define a wiring space 7. The portion of the wire harness exposed outside the control box 4 is located within the wiring space 7.

[0088] For example, the side of the circuit board 42 away from the first receiving cavity 3 has pins, and the wire harness is electrically connected to the pins.

[0089] Wherein, at least a portion of the wiring harness bypasses the outside of the control box 4 and connects to the side of the circuit board 42 away from the first receiving cavity 3, which may include the following situations: for example, a portion of the wiring harness bypasses the outside of the control box 4 and connects to the side of the circuit board 42 away from the first receiving cavity 3; another example is that all the wiring harness bypasses the outside of the control box 4 and connects to the side of the circuit board 42 away from the first receiving cavity 3.

[0090] Since at least a portion of the wiring harness needs to bypass the exterior of the control box 4 to connect to the circuit board 42, these wiring harnesses are exposed on the outside of the box 41, which does not meet safety regulations. By providing a protective cover assembly 6, the protective cover assembly 6 can prevent users from directly contacting these wiring harnesses from the outside, so that the integrated air conditioner 100 can meet safety regulations. In addition, by defining a wiring space 7 between the protective cover assembly 6 and the control box 4, or by the protective cover assembly 6, the control box 4, and the indoor module 10 jointly defining a wiring space 7, the wiring space 7 also facilitates the connection operation of the wiring harness between the indoor module 10 and the circuit board 42.

[0091] refer to Figures 3-5 According to some optional embodiments of the present invention, at least a portion of the heat dissipation duct 5 is located inside the housing 41, and the housing 41 has an airflow inlet 411 that connects the heat dissipation duct 5 to the external space of the integrated air conditioner 100. An air intake structure 611 communicating with the external space of the integrated air conditioner 100 is formed on the protective cover assembly 6, and a wiring space 7 connects the air intake structure 611 to the airflow inlet 411.

[0092] At least a portion of the heat dissipation duct 5 is located inside the housing 41, which may include the following situations: for example, a portion of the heat dissipation duct 5 is located inside the housing 41; or for example, the entire heat dissipation duct 5 is located inside the housing 41.

[0093] For example, under the drive of the indoor fan 21, the airflow in the external space of the integrated air conditioner 100 first enters the wiring space 7 through the air intake structure 611, and then enters the heat dissipation duct 5 through the airflow inlet 411. The airflow entering the heat dissipation duct 5 first flows through part of the heat dissipation duct 5 inside the box 41, then flows through part of the heat dissipation duct 5 between the electrical control box 4 and the indoor heat exchanger 22, and finally flows from the heat dissipation duct 5 through the indoor heat exchanger 22 to the first receiving cavity 3.

[0094] By providing an air intake structure 611 on the protective cover assembly 6, the protective cover assembly 6 can be prevented from obstructing the airflow of the external space into the heat dissipation duct 5 to dissipate heat from the electrical control box 4.

[0095] refer to Figures 2-5According to some optional embodiments of the present invention, the protective cover assembly 6 includes a first protective cover 61 and a second protective cover 62. The first protective cover 61 and the second protective cover 62 are spaced apart along the circumference of the electrical control box 4 and respectively define a first wiring space 71 and a second wiring space 72 that are spaced apart from each other. The circumference of the electrical control box 4 is consistent with the circumference of the circuit board 42. By setting the first protective cover 61 and the second protective cover 62 spaced apart along the circumference of the electrical control box 4 and defining the first wiring space 71 and the second wiring space 72 respectively, the arrangement of the wire harness and the connection between the wire harness and the circuit board 42 are facilitated.

[0096] Optionally, the first protective cover 61 is located on the side closer to the airflow inlet 411 along the first direction, and a near-terminal structure is formed on the first protective cover. The second protective cover 62 is located on the side away from the airflow inlet 411 along the first direction. The second protective cover 62 includes a first cover body and a second cover body that are angled together and connected to each other. A portion of the first cover body is formed into a first contoured structure that adapts to the shape of one end of the electrical control box 4 along a third direction, and a portion of the second cover body is formed into a second contoured structure that adapts to the other side of the electrical control box 4 along the first direction. The first direction, the second direction, and the third direction intersect each other. By forming a contoured structure on the second protective cover 62 that adapts to the outer structure of the electrical control box 4, it is beneficial to improve the sealing degree of the second wiring space 72 defined between the second protective cover 62 and the electrical control box 4, preventing the airflow in the heat dissipation duct 5 from flowing out from the gap between the electrical control box 4 and the second protective cover 62, which is beneficial to improving the heat dissipation effect of the airflow on the electrical control box 4.

[0097] Optionally, the second protective cover 62 has a first surface at one end near the indoor module 10 along the second direction. The first surface fits against the indoor module 10 along the second direction, which helps to further improve the airtightness of the second wiring space 72.

[0098] Optionally, the protective cover assembly 6 and the electrical control box 4 are detachably connected, which facilitates the inspection, maintenance and replacement of the protective cover assembly 6 and the electrical control box 4 respectively.

[0099] Optionally, the first housing 1 is provided with a wiring groove, or the box 41 is provided with a wiring groove, or a wiring groove is defined between the box 41 and the first housing 1, and the wiring groove is located within the wiring space 7. By providing a wiring groove, the arrangement of the wire harness is facilitated, and the wiring groove can limit the structure of the wire harness, which is also conducive to improving the neatness of the wire harness arrangement, and thus improving safety performance.

[0100] refer to Figure 2According to some optional embodiments of the present invention, at least a portion of the heat dissipation duct 5 is located inside the housing 41, and the housing 41 has an airflow inlet 411 that connects the heat dissipation duct 5 to the external space of the integrated air conditioner 100. An air intake structure 611 communicating with the external space of the integrated air conditioner 100 is formed on the first protective cover 61, and a first wiring space 71 connects the air intake structure 611 and the airflow inlet 411.

[0101] At least a portion of the heat dissipation duct 5 is located within the housing 41, which may include the following situations: for example, a portion of the heat dissipation duct 5 is located within the housing 41; or, for example, the entire heat dissipation duct 5 is located within the housing 41. By providing an air intake structure 611 on the protective cover assembly 6, the protective cover assembly 6 can be prevented from obstructing the airflow from the external space into the heat dissipation duct 5 to dissipate heat from the electrical control box 4.

[0102] For example, under the drive of the indoor fan 21, part of the airflow in the external space of the integrated air conditioner 100 first enters the first wiring space 71 through the air intake structure 611, and then enters the heat dissipation duct 5 through the air inlet 411. The airflow entering the heat dissipation duct 5 first flows through part of the heat dissipation duct 5 inside the box 41, then flows through part of the heat dissipation duct 5 between the electrical control box 4 and the indoor heat exchanger 22, and then flows to the second heat dissipation space through the heat dissipation duct 5. Finally, these airflows flow to the first receiving cavity 3.

[0103] refer to Figure 2 According to some optional embodiments of this utility model, the air intake structure 611 includes multiple through holes, which are distributed on the surface of the first protective cover 61 in multiple different directions. By distributing the multiple through holes of the air intake structure 611 on the surface of the first protective cover 61 in multiple different directions, it is beneficial for more airflow to enter the first wiring space 71 through the air intake structure 611, thereby allowing more airflow to enter the heat dissipation duct 5 to dissipate heat from the electrical control box 4, further improving the heat dissipation effect on the electrical control box 4.

[0104] Optionally, the first protective cover 61 has three surfaces located in the first direction, the second direction and the third direction respectively, and through holes are distributed on each of the three surfaces.

[0105] refer to Figures 1-4 According to some optional embodiments of this utility model, the wiring harness includes a first wiring harness and a second wiring harness. The first wiring harness includes a power wire and a ground wire. The second wiring harness is connected to the components 43 on the circuit board 42. The portion of the first wiring harness located outside the control box 4 is located within the first wiring space 71, and the portion of the second wiring harness located outside the control box 4 is located within the second wiring space 72. By placing different wiring harnesses in the first wiring space 71 and the second wiring space 72 respectively, mutual interference between different wiring harnesses is avoided, thus preventing safety hazards. This also facilitates the arrangement and connection of the wiring harnesses.

[0106] refer to Figure 2 According to some optional embodiments of this utility model, the protective cover assembly 6 is detachable. By making the protective cover assembly 6 detachable, it is convenient to inspect and maintain the wire harness within the cable routing space 7.

[0107] According to some embodiments of this utility model, the electrical control box 4 is located at one end of the indoor module 10 along the second direction, and the outdoor module includes a compressor. The compressor is disposed in the second receiving cavity and located at one end of the outdoor module along the second direction. The electrical control box 10 and the compressor are arranged opposite to each other along the first direction. The electrical control box 10 and the compressor are electrically connected, and the electrical control box 10 can be used to control the operation of the compressor. The electrical control box 10 and the compressor are adjacent to each other along the second direction and opposite to each other along the first direction. This arrangement facilitates the connection of the wiring harness between the electrical control box 10 and the compressor.

[0108] refer to Figures 1-4 According to some optional embodiments of the present invention, the indoor module 10 and the outdoor module are spaced apart along a first direction and define a spacer slot 30. By defining the spacer slot 30 between the indoor module 10 and the outdoor module and placing part of the electrical control box 4 assembly within the spacer slot 30, the electrical control box 4 assembly can make full use of the space within the spacer slot 30, thereby optimizing the spatial layout of the integrated air conditioner 100, making the structure of the integrated air conditioner 100 compact, and facilitating the miniaturization of the integrated air conditioner 100.

The second housing has a second air inlet structure that communicates with the second receiving cavity. The second housing has an exhaust vent that communicates with the outdoor environment. The partition groove 30 is used to avoid the ceiling joists of the indoor ceiling. The electrical control box 4 is located above the ceiling joists.

[0110] The air outlet is connected to the first receiving cavity 3, so that the indoor module 10 can send the airflow after cooling or heating regulation to the room through the air outlet. By setting a first air inlet structure on the first housing 1 that is connected to the first receiving cavity 3 and a second air inlet structure on the second housing that is connected to the second receiving cavity, the normal operation of the indoor air supply assembly 2 and the outdoor air supply assembly can be ensured.

[0111] For example, an interior ceiling includes ceiling panels and ceiling joists. The ceiling joists are installed on top of the ceiling panels and connected to them, serving to reinforce the interior ceiling. The ceiling joists can be long strips, and multiple joists can be arranged at intervals on the top of the ceiling panels, saving materials while still reinforcing the interior ceiling. The ceiling panels can be gypsum board, or they can include multiple interlocking panels, which can be aluminum panels.

[0112] By allowing the partition groove 30 to avoid the ceiling joists of the indoor ceiling, the ceiling joists of the indoor ceiling can be accommodated in the partition groove 30 during the installation of the air conditioner, without the need to cut the ceiling joists, simplifying the installation process and improving the installation efficiency of the air conditioner; it can also avoid cutting the joists during the installation process and damaging the structure of the indoor ceiling, ensuring the safety of the indoor ceiling.

[0113] Optionally, a return air vent is formed on the indoor ceiling. The return air vent can be equipped with a return air grille and can be set near the integrated air conditioner 100. Indoor air can flow into the upper space of the indoor ceiling through the return air vent. The air entering the upper space of the indoor ceiling enters the casing, and after the temperature is regulated by the air conditioning components, it is delivered to the room through the air outlet, thereby regulating the indoor ambient temperature and realizing cooling / heating.
