In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0043] The air conditioner 1000 of this utility model is described below with reference to the accompanying drawings.

[0044] According to an embodiment of the present utility model, the air conditioner 1000, such as Figure 1 and Figure 2 As shown, the air conditioner 1000 includes: an air conditioner housing 101 and an electrical control box 200. The electrical control box 200 includes a box body 1 and a circuit board 2. The box body 1 includes a box base 11, a first box cover 12 and a second box cover 13. The box base 11 is disposed on the air conditioner housing 101. The second box cover 13 is disposed on the side of the box base 11 away from the interior of the air conditioner housing 101. The first box cover 12 is disposed between the box base 11 and the second box cover 13. A first receiving cavity 1a is formed between the first box cover 12 and the box base 11. A second receiving cavity 1b is formed between the first box cover 12 and the second box cover 13. The circuit board 2 is disposed in the first receiving cavity 1a. The wiring harness connected to the circuit board 2 is a connector wiring harness 3. At least a portion of the connector wiring harness 3 extends into the second receiving cavity 1b.

[0045] The air conditioner 1000 includes an air conditioner housing 101, and an electrical control box 200 is disposed on the air conditioner housing 101 and located on the outer side of the interior of the air conditioner housing 101, facilitating the installation and maintenance of the electrical control box 200. The box base 11 of the electrical control box 200 is open towards the side facing away from the interior of the air conditioner housing 101, and a second cover 13 is disposed on the side of the box base 11 facing away from the interior of the air conditioner housing 101. The electrical control box 200 has a relatively large space away from the interior of the air conditioner housing 101, which facilitates the arrangement and opening / closing of the electrical control box 200, and also facilitates its installation and maintenance.

[0046] The box body 1 includes a box base 11, a first box cover 12 and a second box cover 13. The second box cover 13 covers the box base 11. The first box cover 12 is located between the box base 11 and the second box cover 13. A first receiving cavity 1a is formed between the first box cover 12 and the box base 11. A second receiving cavity 1b is formed between the first box cover 12 and the second box cover 13. A circuit board 2 is located in the first receiving cavity 1a. At least a portion of the board wiring harness 3 connected to the circuit board 2 extends out of the circuit board 2 and into the second receiving cavity 1b.

[0047] The formation of a second receiving cavity 1b between the first lid 12 and the second lid 13 means that the second receiving cavity 1b is defined by at least the first lid 12 and the second lid 13; alternatively, the second receiving cavity 1b may be defined by both the first lid 12 and the second lid 13; or, the second receiving cavity 1b may be defined by the box base 11, the first lid 12 and the second lid 13 together; or, the second receiving cavity 1b may be defined by the first lid 12, the second lid 13 and more parts together.

[0048] By providing the first cover 12, the circuit board 2 located in the first receiving cavity 1a and the wiring harness 3 extending to the second receiving cavity 1b are separated. The first cover 12 isolates the wiring harness from the circuit board 2 and the onboard electrical components 23 on the circuit board 2, thereby achieving better safety isolation of the electrical components and reducing interference and contact between the wiring harness and the onboard electrical components 23.

[0049] It is understandable that when the air conditioner 1000 is installed at the point of use, the functional modules need to be electrically connected to the circuit board 2, such as lighting components or purification components, and are jointly controlled by the electrical control box 200.

[0050] This invention, by providing a first cover 12 to extend the connector wire harness 3 into the second receiving cavity 1b, allows for quick and easy connection of the connector wire harness 3 by simply opening the second cover 13 when connecting external wire harnesses to the control box 200. This improves the situation where wire harnesses become tangled and difficult to connect within the control box 200, making the connection of external wire harnesses 6 to the connector wire harness 3 convenient and quick. The first cover 12 separates the first receiving cavity 1a and the second receiving cavity 1b, and also reduces accidental contact with the circuit board 2 when connecting external wire harnesses to the connector wire harness 3, thus better achieving safe isolation of electrical components and improving the operational reliability of the control box 200.

[0051] According to the embodiment of the present invention, the air conditioner 1000, by providing a first cover 12, separates the circuit board 2 disposed in the first receiving cavity 1a from the wiring harness 3 extending to the second receiving cavity 1b, reducing interference and contact between the wiring harness and the circuit board 2 and the electrical components 23 on the board, thus achieving better safety isolation of the electrical components. Furthermore, by providing the first cover 12 to partially isolate the wiring harness 3 in the second receiving cavity 1b, it facilitates the untangling of the wiring harness, improves the situation of the wiring harness becoming entangled within the electrical control box 200, and is beneficial for subsequent wiring and reliable operation of the wiring harness.

[0052] In some embodiments of this utility model, such as Figure 3 As shown, the box base 11 includes a partition structure 111 located in the first receiving cavity 1a. The partition structure 111 divides the space inside the box base 11 into multiple sub-regions 11c. The electrical control box 200 also includes an external electrical component 4 disposed in the first receiving cavity 1a. The circuit board 2 and the external electrical component 4 are respectively disposed in different sub-regions 11c, so as to separate the external electrical component 4 and the circuit board 2 by the partition structure 111.

[0053] By placing the external electrical components 4, which are located outside the control box 200 in the related technology, inside the control box 200, the external space occupied by the external electrical components 4 when they are placed on the air conditioner housing 101 can be reduced, which is conducive to reducing the volume of the air conditioner 1000. On the other hand, the box body 1 of the control box 200 can protect the external electrical components 4 and improve the working reliability of the external electrical components 4.

[0054] Because a partition structure 111 is provided within the first receiving cavity 1a, the space within the box base 11 is divided into multiple sub-regions 11c. The circuit board 2 and the external electrical components 4 are respectively located in different sub-regions 11c. The compact arrangement of the circuit board 2 and the external electrical components 4 helps to reduce the volume of the electrical control box 200. Furthermore, the partition structure 111 separates the external electrical components 4 from the circuit board 2, which can better achieve safe isolation between the onboard electrical components 23 on the circuit board 2 and the external electrical components 4, reduce interference and contact between electrical components, and increase fire resistance.

[0055] In some embodiments of this utility model, such as Figure 3 As shown, there are multiple external electrical components 4, which are respectively located in multiple sub-regions 11c, with adjacent external electrical components 4 separated by a partition structure 111.

[0056] There are multiple external electrical components 4, and multiple sub-regions 11c are correspondingly set. The multiple external electrical components 4 are respectively set in multiple sub-regions 11c. The separation structure 111 also separates the multiple external electrical components 4, thereby achieving better safety isolation between the external electrical components 4 and reducing interference and contact between the external electrical components 4. Furthermore, the separation structure 111 divides into multiple independent sub-regions 11c, and the external electrical components 4 are respectively set in the sub-regions 11c, which can improve the arrangement stability of the external electrical components 4.

[0057] In other embodiments of this utility model, there are multiple external electrical components 4, and the multiple external electrical components 4 are disposed in the same sub-region 11c.

[0058] The partition structure 111 separates the external electrical components 4 from the circuit board 2, and the multiple external electrical components 4 are located in the same sub-region 11c, which can reduce the space occupied by the external electrical components 4, which is beneficial to reduce the volume of the electrical control box 200 and save the manufacturing cost of the electrical control box 200.

[0059] In some embodiments of this utility model, such as Figure 3 As shown, the external electrical component 4 is electrically connected to the circuit board 2 and includes at least one of the functional module driver 41 and the magnetic ring 42.

[0060] The functional module driver 41 is a driver for the functional modules controlled by the control box 200. For example, the functional module driver 41 can be a lighting module driver or a negative ion module driver. The lighting module driver or negative ion module driver is electrically connected to the circuit board 2, and the circuit board 2 can control the operation of the lighting module or negative ion module. Placing the functional module driver 41 within the first receiving cavity 1a, and keeping it close to the circuit board 2, facilitates the electrical connection between the functional module driver 41 and the circuit board 2, shortens the wire harness length, and improves the situation where the long wire harness inside the control box 200 causes tangling.

[0061] The magnetic ring 42 is used to suppress electromagnetic interference and protect electrical circuits. Placing the magnetic ring 42 in the first receiving cavity 1a can protect the magnetic ring 42 and improve working stability. Furthermore, the magnetic ring 42 is close to the circuit board 2, which is conducive to the electrical connection between the magnetic ring 42 and the circuit board 2, shortens the wire harness length, and can improve the situation where the wire harness in the electrical control box 200 is too long and tangled together.

[0062] In some embodiments of this utility model, such as Figure 1 , Figure 3 and Figure 4 As shown, the partition structure 111 includes a first partition 1111, and the box base 11 is disposed on the vertical side wall of the air conditioner housing 101. The first partition 1111 extends vertically, and a first region 112 and a second region 113 are respectively provided on the horizontal sides of the first partition 1111. The first region 112 is a sub-region 11c and is provided with a circuit board 2. The second region 113 includes at least one sub-region 11c and is provided with an external electrical component 4.

[0063] The box base 11 is located on the vertical side wall of the air conditioner housing 101. This means that the air conditioner 1000 is in the normal working position. The box base 11 is located on the side wall of the air conditioner housing 101 that extends in the vertical direction. The box base 11 extends in the direction of gravity. The second box cover 13 is located on one side of the box base 11 in the horizontal direction.

[0064] The first partition 1111 extends vertically and divides the space inside the box 11 into a first region 112 and a second region 113 that are horizontally spaced. The first region 112 and the second region 113 have the same size in the vertical direction. The first region 112 and the second region 113 have larger sizes, which can accommodate the external electrical components 4 of the circuit board 2.

[0065] In some embodiments of this utility model, such as Figure 3 As shown, the partition structure 111 includes a second partition 1112, which is disposed in the second region 113 and divides the second region 113 into a plurality of sub-regions 11c that are arranged vertically at intervals.

[0066] The first partition 1111 divides the space inside the box base 11 into a first region 112 and a second region 113 arranged horizontally. The second partition 1112 further divides the second region 113 into multiple sub-regions 11c arranged vertically. The space inside the box base 11 is rationally divided, and the multiple sub-regions 11c are isolated from each other and closely arranged, which makes the structure of the electrical control box 200 compact and helps to reduce the volume of the electrical control box 200. Furthermore, the rational planning of the internal space allows the electrical control box 200 to accommodate more external electrical components 4, thereby achieving the goal of reducing structural parts and helping to reduce the overall size of the air conditioner 1000.

[0067] In some embodiments of this utility model, such as Figure 3 As shown, there are multiple external electrical components 4, including a magnetic ring 42 and a functional module driver 41. Both the magnetic ring 42 and the functional module driver 41 are disposed in the second region 113 and arranged vertically.

[0068] The functional module driver 41 and the magnetic ring 42 are both located in the second region 113. The distance between the functional module driver 41 and the magnetic ring 42 and the circuit board 2 in the first region 112 is reduced, which is beneficial to the electrical connection between the functional module driver 41 and the magnetic ring 42 and the circuit board 2, shortens the wire harness length, and can improve the situation where the wire harness in the electrical control box 200 is too long and tangled together.

[0069] The magnetic ring 42 and the functional module driver 41 are both located in the second region 113 and arranged vertically, which is compact and helps to reduce the size of the electrical control box 200.

[0070] In some embodiments of this utility model, such as Figure 3 As shown, the magnetic ring 42 and the functional module driver 41 are both disposed in the second region 113 and arranged vertically, and the second partition 1112 separates the magnetic ring 42 and the functional module driver 41.

[0071] By setting the first partition 1111 and the second partition 1112, the space inside the box 11 is divided into a 'two-room, one-hall' structure. The magnetic ring 42 and the functional module driver 41 are arranged compactly, occupying less space inside the electrical control box 200, which helps to reduce the volume of the electrical control box 200. Furthermore, the second partition 1112 separates the magnetic ring 42 and the functional module driver 41, reducing interference and contact between the magnetic ring 42 and the functional module driver 41, and increasing fire safety.

[0072] In some embodiments of this utility model, the functional module driver 41 includes a lighting module driver.

[0073] In some embodiments of this utility model, such as Figure 2 and Figure 5 As shown, a heat sink 7 is provided on the circuit board 2. The heat sink 7 is located on the side of the circuit board 2 away from the second region 113. The first cover 12 has a clearance hole 121 corresponding to the heat sink 7. The heat sink 7 extends out of the first cover 12 through the clearance hole 121; or the first cover 12 has a heat dissipation hole corresponding to the heat sink 7.

[0074] The first partition 1111 extends vertically, dividing the space within the housing 11 into a first region 112 and a second region 113, which are horizontally spaced. The first region 112 and the second region 113 have the same vertical dimensions. The heat sink 7 is positioned on the side of the circuit board 2 away from the second region 113, providing ample space for its placement and improving its heat dissipation effect on the circuit board 2. The heat sink 7 and the external electrical components 4 are placed on opposite sides of the circuit board 2 in the horizontal direction. The rational planning of the internal space of the housing 11 results in a compact structure for the electrical control box 200, which helps reduce its volume and thus achieves the goal of reducing structural components.

[0075] The first cover 12 has a clearance hole 121 or heat dissipation hole corresponding to the heat sink 7. The heat sink 7 can exchange heat with the airflow in the direction away from the first mounting cavity 1011. This direction has a large space and good airflow, which can improve the heat dissipation effect.

[0076] In some embodiments of this utility model, such as Figure 2 and Figure 5 As shown, the first cover 12 has a clearance hole 121 corresponding to the radiator 7. The clearance hole 121 is arranged around the radiator 7 to form an airflow passage communicating with the radiator 7. The radiator 7 extends out of the first cover 12 through the clearance hole 121 to improve the stability of the airflow.

[0077] In some embodiments of this utility model, such as Figure 1 and Figure 6 As shown, the second cover 13 has a flow hole 132 corresponding to the heat sink 7. The second cover 13 connects the space on the side of the base 11 away from the first mounting cavity 1011 with the heat sink 7. The heat sink 7 can exchange heat with the airflow away from the first mounting cavity 1011, which is beneficial to improving the heat exchange effect.

[0078] In related technologies, the electrical control box includes a main cover that defines the space for accommodating the circuit board, a base cover for dissipating heat from the heat sink, and a right cover for limiting the wiring harness.

[0079] This utility model separates the first receiving cavity 1a and the second receiving cavity 1b within the electrical control box 200 by setting a first cover 12, forming a double-layer structure. The second receiving cavity 1b can limit the wire harness, and the first cover 12 and the second cover 13 can dissipate heat from the heat sink 7. The box base 11 accommodates the circuit board 2, thereby simplifying the structural components, reducing production costs, reducing the number of parts and steps for maintenance, and making production, installation and maintenance more convenient and efficient.

[0080] In some embodiments of this utility model, such as Figure 1 and Figure 6 As shown, the radiator 7 includes multiple heat sinks, forming an airflow gap between two adjacent heat sinks. The second cover 13 has multiple flow holes 132 that correspond to and are connected to the airflow gaps one by one.

[0081] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the circuit board 2 is disposed on the housing 11, and the side of the circuit board 2 facing the first housing cover 12 is provided with a wire harness connection terminal 22 and an onboard electrical component 23.

[0082] Since the circuit board 2 has a wire harness connection terminal 22 and an onboard power supply 23 on the side facing the first cover 12, that is, the circuit board 2 has a wire harness connection terminal 22 and an onboard power supply 23 on the side facing away from the first mounting cavity 1011, and the electrical control box 200 has a large space on the side facing away from the first mounting cavity 1011, the circuit board 2 is set in the above position, which facilitates the maintenance and wiring of the circuit board 2 and reduces the difficulty of operation.

[0083] In some embodiments of this utility model, such as Figure 2 and Figure 5 As shown, the first box cover 12 has a first opening 122, which connects the first receiving cavity 1a and the second receiving cavity 1b. The board wiring harness 3 includes a first wiring harness 31, and the end of the first wiring harness away from the circuit board 2 has a first plug terminal 311. The first plug terminal 311 extends from the first receiving cavity 1a into the second receiving cavity 1b through the first opening 122.

[0084] The first cover 12 separates the circuit board 2 located in the first receiving cavity 1a from the first wire harness 31 extending to the second receiving cavity 1b, thereby better achieving safe isolation of electrical components and reducing interference and contact between the wire harness and the electrical components 23 on the board.
