The terminal block 4 is connected to the ground wire connection part 11 through the ground wire 6, and the ground wire 6 is fixed to the grounding plate 5.

[0045] Specifically, the evaporator 1 is used to realize the cooling function of the air-conditioning wall unit 100. A ground wire connection part 11 is provided on the evaporator 1. The ground wire 6 can be connected to the evaporator 1 through the ground wire connection part 11, so that when the evaporator 1 leaks electricity, the leakage can be directed to the ground to protect personal safety and equipment safety.

It is mainly responsible for various functions of the air-conditioning system and ensures that the air-conditioning system operates according to the set mode and parameters. The electric control box 2 and the evaporator 1 are distributed along the length direction of the air-conditioning wall unit 100, so that the electric control box 2 and the evaporator 1 can be separated and distributed to avoid interference between the two, which causes the air-conditioning wall unit 100 to be unable to be used normally, and can reduce the space occupied by the air-conditioning wall unit 100 in the width and height directions, which is conducive to the setting of the air-conditioning wall unit 100.

[0046] At the same time, the air-conditioning motor is connected to the air-conditioning fan so that the air-conditioning motor can provide driving force to the air-conditioning fan, driving the air-conditioning fan to rotate to promote air flow, and the air-conditioning motor has a motor cover 31, which is used to cover the air-conditioning motor and protect the internal components of the air-conditioning motor from the invasion of external impurities, dust, moisture and other pollutants, thereby improving the reliability of the air-conditioning motor.

The ground wire 6 is connected between the ground wire connection part 11 and the terminal block 4 through the grounding plate 5, so that the leakage current of the evaporator 1 can be guided along the ground wire 6 to the grounding plate 5 first, and then from the grounding plate 5 along the ground wire 6 to the terminal block 4, and is conducted to the ground at the terminal block 4.

[0049] Among them, it should be noted that installing the grounding plate 5 on the motor cover 31 can meet the installation requirements of the ground wire 6, and does not require additional components, which can reduce the installation cost. At the same time, it is not restricted by the structure of the electrical control box 2, and can avoid the grounding plate 5 occupying the internal and external space of the electrical control box 2, thereby reducing the impact of the grounding plate 5 on the body length of the air-conditioning wall-mounted unit 100, which is beneficial to the installation of the air-conditioning wall-mounted unit 100.

[0050] Thus, the evaporator 1 is used to realize the cooling function of the air-conditioning hanging unit 100, and a terminal block 4 is installed in the electrical control box 2 so that the wires and cables can be connected to the circuit board in the electrical control box 2 here to realize various functions of the air-conditioning system. At the same time, a ground wire connecting part 11 is provided on the evaporator 1 to connect the ground wire 6, and the ground wire connecting part 11 is connected to the terminal block 4 through the ground wire 6, and the ground wire 6 is fixed to the grounding plate 5, so that the ground wire 6 can connect the ground wire connecting part 11 with the terminal block 4 through the grounding plate 5, and then the ground wire 6 can guide the leakage of the evaporator 1 to the ground at the terminal block 4, and the grounding plate 5 is installed on the motor cover 31, which can meet the installation requirements of the ground wire 6 and avoid the grounding plate 5 occupying the internal and external space of the electrical control box 2.

In addition, the grounding plate 5 is installed on the motor cover 31, which can meet the installation requirements of the ground wire 6, and is not restricted by the structure of the electric control box 2, and can avoid the grounding plate 5 occupying the internal and external space of the electric control box 2, which can reduce the influence of the grounding plate 5 on the body length of the air-conditioning wall unit 100, and is beneficial to the setting of the air-conditioning wall unit 100.

The detachable connection between the terminal block 4 and the electric control box 2 can be achieved by connecting parts such as bolts, and the connection method is simple, reliable and easy to operate.

[0054] In addition, the grounding plate 5 is installed on the motor cover 31, which can prevent the grounding plate 5 from occupying the internal and external space of the electric control box 2. The grounding plate 5 can be detachably installed on the motor cover 31, which can facilitate the connection of the grounding plate 5 to the motor cover 31, or the separation of the two. When the grounding plate 5 is connected to the motor cover 31, the connection to the ground wire 6 can be achieved. When the grounding plate 5 is separated from the motor cover 31, the grounding plate 5 can be replaced, which can reduce the subsequent maintenance cost. The detachable connection between the grounding plate 5 and the motor cover 31 can be achieved by connecting parts such as bolts, and the connection method is simple, reliable and easy to operate.

[0055] In some embodiments, the terminal block 4 is provided with a first plug-in positioning portion 41 and a first connecting portion 42, and the electrical control box 2 is provided with a second plug-in positioning portion 21 and a second connecting portion 22; wherein, the first plug-in positioning portion 41 is plugged and positioned with the second plug-in positioning portion 21, and the first connecting portion 42 is detachably connected with the second connecting portion 22 through a first connecting member 421.

[0056] Specifically, the terminal block 4 is detachably mounted on the electrical control box 2, and a first plug-in positioning portion 41 and a first connecting portion 42 are provided on the terminal block 4. The first plug-in positioning portion 41 is used to realize the positioning of the terminal block 4, and the first connecting portion 42 is used to realize the fixation of the terminal block 4. A second plug-in positioning portion 21 and a second connecting portion 22 are provided on the electrical control box 2. The second plug-in positioning portion 21 is used to plug and position with the first plug-in positioning portion 41 to ensure the accuracy of the installation position of the terminal block 4, and the second connecting portion 22 is used to be connected to the first connecting portion 42 through the first connecting member 421 to connect the terminal block 4 to the electrical control box 2, and the first connecting portion 42 and the second connecting portion 22 are detachably connected through the first connecting member 421, which can facilitate the connection of the terminal block 4 to the electrical control box 2 to realize the installation of the terminal block 4, or the separation of the terminal block 4 from the electrical control box 2 to realize the disassembly of the terminal block 4, thereby facilitating the replacement of the terminal block 4 and reducing the later maintenance cost.

[0057] Among them, the first plug-in positioning portion 41 and the second plug-in positioning portion 21 can be arranged opposite to each other, so that the first plug-in positioning portion 41 and the second plug-in positioning portion 21 can be plugged together to achieve the positioning of the docking terminal 4, and the first connecting portion 42 and the second connecting portion 22 can be arranged opposite to each other, so that the first connecting part 421 can pass through the first connecting portion 42 and the second connecting portion 22 in sequence to achieve the fixation of the docking terminal 4, so that the terminal holder 4 can be installed by first positioning and then connecting, which can effectively improve the reliability of the installation of the docking terminal 4.

[0058] In some embodiments, the first plug-in positioning portion 41 and the first connecting portion 42 are respectively located at two opposite edges of the terminal block 4 , and the first plug-in positioning portion 41 is suitable for being plugged into the second plug-in positioning portion 21 in a direction away from the second connecting portion 22 .

[0059] Specifically, the first plug-in positioning portion 41 is used for positioning the terminal block 4, and the first connecting portion 42 is used for installing the terminal block 4. The first plug-in positioning portion 41 and the first connecting portion 42 are respectively arranged at the two side edges that are relatively distributed on the terminal block 4, so that the first plug-in positioning portion 41 and the first connecting portion 42 can be spaced apart and arranged to achieve the cooperation between the terminal block 4 and the electrical control box 2 from two relative positions at the same time, which can improve the connection reliability between the two, balance the force, and improve the connection stability between the two. In addition, the first plug-in positioning portion 41 can be plugged into the second plug-in positioning portion 21 in a direction away from the second connecting portion 22, that is, the first plug-in positioning portion 41 can be plugged into the second plug-in positioning portion 21 from the second connecting portion 22 toward the second plug-in positioning portion 21, so as to achieve positioning cooperation between the terminal block 4 and the electrical control box 2.

Moreover, the first connecting member 421 can be a self-tapping screw.

[0061] In some embodiments, the grounding plate 5 is detachably connected to the motor cover 31 via at least one second connecting member 51 .

[0062] Specifically, the grounding plate 5 can be detachably mounted on the motor cover 31, and the grounding plate 5 can be detachably connected to the motor cover 31 through the second connecting member 51, so that the grounding plate 5 can be easily connected to the motor cover 31, or the two can be separated, and there is at least one second connecting member 51, that is, the number of second connecting members 51 can be one, two or three, etc., and the grounding plate 5 can be connected to the motor cover 31 through at least one second connecting member 51, and the second connecting member 51 can be a bolt.

[0063] In such Figure 1 、 Figure 3-Figure 5 In the embodiment shown, there is only one second connecting member 51, that is, the grounding plate 5 can be connected to the motor cover 31 through one second connecting member 51, and the number of second connecting members 51 is not limited to that described in this embodiment, and can be flexibly set according to specific needs and space size.

[0064] In some embodiments, the motor cover 31 and the electric control box 2 are located at the same end of the evaporator 1 , and the grounding plate 5 is located between the evaporator 1 and the electric control box 2 in the length direction of the air conditioner 100 .

[0065] Specifically, the air-conditioning motor is connected to the evaporator 1 for realizing the cooling function, and the electrical control box 2 is connected to the evaporator 1 for realizing functions such as temperature control and mode control. The motor cover 31 and the electrical control box 2 are both arranged at the same end of the evaporator 1, so that the air-conditioning motor and the electrical control box 2 can be conveniently connected to the evaporator 1 at the same time, and the structure can be made compact, reducing the occupied space of the air-conditioning hanging unit 100, and facilitating the setting of the air-conditioning hanging unit 100. In addition, the grounding plate 5 is arranged between the evaporator 1 and the electrical control box 2, so that the grounding plate 5 is close to the evaporator 1 and the electrical control box 2, so that the ground wire 6 can be connected between the ground wire connection part 11 and the terminal block 4 through the grounding plate 5.

[0066] In some embodiments, the two ends of the ground wire 6 are respectively connected to the terminal block 4 and the ground wire connecting part 11, and the motor cover 31 is provided with a winding part 311; the middle part of the ground wire 6 is wound around the winding part 311, and both ends of the ground wire 6 are higher than the middle part of the ground wire 6.

[0067] Specifically, the ground wire 6 can be connected between the ground wire connection part 11 and the terminal block 4 through the grounding plate 5, that is, the two ends of the ground wire 6 are respectively connected to the terminal block 4 and the ground wire connection part 11, and the motor cover 31 is provided with a winding part 311, which is used for winding. The middle part of the ground wire 6 is wound around the winding part 311, so that the winding part 311 can limit the ground wire 6 and allow the ground wire 6 to extend along the set direction to avoid the ground wire 6 from being entangled in the air-conditioning hanging unit 100, and the middle part of the ground wire 6 can be bent at a certain arc at the winding part 311, so that both ends of the ground wire 6 are higher than the middle part of the ground wire 6, that is, the middle part of the ground wire 6 is the lowest point of the ground wire 6, which is lower than the connection between the ground wire 6 and the ground wire connection part 11 and the terminal block 4, so that water droplets dripping from the evaporator 1 will not be introduced into the electrical control box 2 along the ground wire 6, causing a short circuit or fire.

[0068] For example, Figure 7 As shown, a wire outlet 43 can be provided on the side of the terminal block 4 facing the grounding plate 5 so that the ground wire 6 can extend from here to be connected to the grounding plate 5, and the edge of the wire outlet 43 can be made smooth to avoid scratching the ground wire 6. Moreover, the size of the wire outlet 43 should not be too large to reduce the possibility of water droplets entering the electrical control box 2.

[0069] In some embodiments, the winding portion 311 is located below the grounding plate 5 , and a winding opening 3111 is formed in the winding portion 311 . The winding opening 3111 is configured to be open downward and pass through both sides in the horizontal direction, and the ground wire 6 is wound around the winding opening 3111 .

[0070] Specifically, the winding portion 311 is arranged below the grounding plate 5, so that the winding portion 311 can be arranged between the evaporator 1 and the electric control box 2, and the water droplets dripping from the evaporator 1 will not be guided to the grounding plate 5 along the grounding wire 6. The winding portion 311 is formed with a winding opening 3111. The grounding wire 6 is wound around the winding opening 3111, so that the grounding wire 6 and the winding portion 311 can be matched, so that the winding portion 311 can limit the extension direction of the grounding wire 6. In addition, the winding opening 3111 is constructed to be open downward to facilitate the grounding wire 6 to be wound from the grounding plate 5. The lower end of the winding mouth 3111 extends into the winding mouth 3111, and the winding part 311 can be constructed into an arc shape to limit the extension direction of the ground wire 6. At the same time, the winding mouth 3111 is penetrated on both sides in the horizontal direction, and the winding part 311 can be connected to the side of the evaporator 1 and the side of the electrical control box 2 through the winding mouth 3111, so that the ground wire 6 can pass through the winding mouth 3111 and be connected to the ground wire connecting part 11 and the terminal block 4 respectively, so as to guide the leakage of the evaporator 1 to the ground at the terminal block 4, thereby protecting personal safety and equipment safety.

[0071] In some embodiments, the motor cover 31 is provided with a first water retaining portion 32 . The first water retaining portion 32 is located above the grounding plate 5 and protrudes and extends away from the motor cover 31 to shield the grounding plate 5 .

[0072] Specifically, the first water retaining portion 32 is used to shield the grounding plate 5. The first water retaining portion 32 is arranged above the grounding plate 5 so that the first water retaining portion 32 can be used to prevent water droplets dripping from the evaporator 1 from dripping onto the grounding plate 5, thereby improving the reliability of the grounding plate 5. The first water retaining portion 32 is arranged on the motor cover 31 and protrudes and extends in a direction away from the motor cover 31, so that the first water retaining portion 32 has a certain length to increase the area that the first water retaining portion 32 can shield the grounding plate 5, thereby effectively improving the reliability of the first water retaining portion 32 in shielding the grounding plate 5.

[0073] It should be noted that the first water retaining portion 32 may be constructed in a flat plate shape and extended upwardly in an inclined manner to further enhance the reliability of the first water retaining portion 32 in shielding the grounding sheet 5 .

[0074] In some embodiments, the motor cover 31 is provided with a second water retaining portion 33, the second water retaining portion 33 is located above the grounding plate 5 and close to one side of the electrical control box 2, at least part of the ground wire 6 is configured to lead to the grounding plate 5 along the second water retaining portion 33, and the second water retaining portion 33 blocks at least part of the ground wire 6 on the side facing the evaporator 1.

[0075] Specifically, the second water retaining portion 33 is used to shield at least part of the ground wire 6. The second water retaining portion 33 is arranged above the grounding plate 5 and close to the side of the electrical control box 2, and at least part of the ground wire 6 is arranged to be led to the grounding plate 5 along the second water retaining portion 33, so that at least part of the ground wire 6 can be made to have the same extension direction as the second water retaining portion 33, which can increase the reliability of the second water retaining portion 33 in shielding at least part of the ground wire 6. In addition, the second water retaining portion 33 is shielded on the side of at least part of the ground wire 6 facing the evaporator 1, so that the second water retaining portion 33 can be arranged between the evaporator 1 and at least part of the ground wire 6 to effectively prevent water droplets dripping from the evaporator 1 from splashing onto the ground wire 6 and being introduced into the electrical control box 2, causing a short circuit or fire.

[0076] It should be noted that the second water retaining portion 33 can be extended outward from the motor cover 31 to increase the area of ​​the second water retaining portion 33 and improve the reliability of the operation of the second water retaining portion 33, and the first water retaining portion 32 can be connected to the second water retaining portion 33 to further improve the reliability of the first water retaining portion 32 and the second water retaining portion 33 in blocking water droplets dripping from the evaporator 1.

[0077] In some embodiments, the air conditioner wall unit 100 also includes an air conditioner surface frame 7, and the evaporator 1, the electrical control box 2 and the air conditioner motor are all installed on the inner side of the air conditioner surface frame 7. The air conditioner surface frame 7 is formed with a first operating port 71 and a second operating port 72. The first operating port 71 is directly opposite to the terminal block 4, and the second operating port 72 is directly opposite to the grounding plate 5.

[0078] Specifically, the air conditioning surface frame 7 is used to shield the components inside the air conditioning hanging unit 100. The evaporator 1, the electrical control box 2 and the air conditioning motor are all installed on the inner side of the air conditioning surface frame 7. The air conditioning surface frame 7 can protect the evaporator 1, the electrical control box 2 and the air conditioning motor from the invasion of external impurities, dust, moisture and other pollutants, thereby improving the reliability of the operation of the evaporator 1, the electrical control box 2 and the air conditioning motor. The air conditioning surface frame 7 is formed with a first operating port 71 and a second operating port 72. The first operating port 71 and the second operating port 72 can both provide maintenance personnel with positions for operation, ensuring sufficient vision and convenient operation. The first operating port 71 is distributed opposite to the terminal block 4, so that the maintenance personnel can extend the fixing tool from the first operating port 71 to the terminal block 4 to connect the wires or cables. At the same time, the second operating port 72 is distributed opposite to the grounding plate 5, so that the maintenance personnel can extend the fixing tool from the second operating port 72 to the grounding plate 5 to fix the ground wire 6.

[0079] Among them, it should be noted that the edge of the second operating port 72 can be flanged to avoid the position of the second connecting member 51, and the grounding plate 5 can be installed on the motor cover 31, which can increase the distance between the grounding plate 5 and the terminal block 4, increase the routing distance of the ground wire 6, and fully consume the excess wire, so that the ground wire 6 does not need to be sharply bent to be plugged into the inside of the terminal block 4, which can better organize the wires and improve the convenience of assembly.

[0080] In some embodiments, the first operation port 71 is in communication with the second operation port 72 .

[0081] Specifically, the first operating port 71 is opposite to the terminal block 4, the second operating port 72 is opposite to the grounding plate 5, and the ground wire 6 connects the ground wire connecting portion 11 to the terminal block 4 through the grounding plate 5, that is, the ground wire 6 can connect the grounding plate 5 to the terminal block 4, and the first operating port 71 is connected to the second operating port 72, so that the ground wire 6 can extend from the terminal block 4 to the grounding plate 5 to be connected to the grounding plate 5, thereby realizing the connection of the ground wire 6 between the evaporator 1 and the terminal block 4.

[0082] In some embodiments, the terminal block 4 is connected to a connecting wire 9 and / or a power wire 10 .

[0083] That is to say, the terminal block 4 is connected to the connecting wire 9 or the power wire 10, or the terminal block 4 is connected to the connecting wire 9 and the power wire 10 at the same time, so that when the ground wire 6 is connected to the terminal block 4, the ground wire 6 can be connected to the connecting wire 9 and / or the power wire 10, and then the ground wire 6 can be connected to the ground, so that when the evaporator 1 leaks electricity, the leakage of the evaporator 1 can be directed to the ground, thereby protecting personal safety and equipment safety.

[0084] In some embodiments, the air conditioner hanging unit 100 further includes a wire clamp 8 , which is detachably connected to the electric control box 2 , and is used to fix the connecting wire 9 and / or the power cord 10 .

[0085] Specifically, the wire clamp 8 is used to fix the connecting wire 9 or the power cord 10, or to fix the connecting wire 9 and the power cord 10 at the same time, so as to avoid the connecting wire 9 and / or the power cord 10 from shaking, which may reduce the connection reliability with the terminal block 4. The wire clamp 8 can be detachably connected to the electrical control box 2 by connecting parts such as bolts, so that the wire clamp 8 can be easily connected to the electrical control box 2 or the two can be separated. When the wire clamp 8 is connected to the electrical control box 2, the wire clamp 8 can be fixed, thereby improving the working reliability of the wire clamp 8. When the wire clamp 8 is separated from the electrical control box 2, the connecting wire 9 and / or the power cord 10 can be easily fixed.

[0086] In such Figure 4 In the embodiment shown, the terminal block 4 is connected to the connecting wire 9 and the power wire 10 at the same time. When the ground wire 6 is connected to the terminal block 4, the ground wire 6 can be connected to the connecting wire 9 and the power wire 10 at the same time, which can effectively conduct the ground wire 6 to the ground, thereby improving the reliability of conducting the leakage of the evaporator 1 to the ground, and the connecting wire 9 and the power wire 10 can be fixed at the same time by the wire clamp 8, which can reduce the number of wire clamps 8 and reduce the installation cost.

[0087] Furthermore, a threading hole can be provided in the wire clamp 8 , and the connecting wire 9 and the power cord 10 can be passed through the threading hole to prevent the wire clamp 8 from squeezing the connecting wire 9 and the power cord 10 and causing damage to the connecting wire 9 and the power cord 10 .

[0088] In some embodiments, the ground wire 6 is detachably fixed to the ground plate 5 via a third connecting member 52 .

[0089] Specifically, the ground wire 6 is fixed to the grounding plate 5, and the ground wire 6 can be detachably fixed to the grounding plate 5 through the third connecting member 52, that is, the ground wire 6 can be connected to the grounding plate 5 or separated from the grounding plate 5 through the third connecting member 52. When the ground wire 6 is connected to the grounding plate 5, the connection of the ground wire 6 between the evaporator 1 and the terminal block 4 can be realized. When the ground wire 6 is separated from the grounding plate 5, the evaporator 1 can be disconnected from the terminal block 4 to facilitate the replacement of the grounding plate 5, wherein the third connecting member 52 can be a grounding screw.

[0090] For example, Figure 2 and Figure 6As shown, a grounding hole 53 can be provided on the grounding plate 5, and the third connecting member 52 can be passed through the grounding hole 53 to fix the ground wire 6. An avoidance groove 312 can be provided on the motor cover 31 at a position opposite to the grounding hole 53 to avoid the third connecting member 52 and ensure the reliable connection of the third connecting member 52. The avoidance groove 312 can be constructed as a cylindrical groove to meet the assembly requirements of the grounding plate 5.

[0091] Therefore, when maintenance personnel are wiring, they can first fix the connecting wire 9 and the power cord 10 on the electrical control box 2 through the wire clamp 8 at the first operating port 71, and then connect the connecting wire 9 and the power cord 10 to the terminal block 4. The ground wire 6 can pass through the outlet 43 and extend along the second water retaining portion 33, and be fixed to the grounding plate 5 through the grounding screw. The fixing tool can be extended into the interior of the fuselage through the first operating port 71 to fix this grounding screw.
