[0037] The embodiments of this utility model are described in detail below. Examples of these 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.

[0038] refer to Figures 1-2 An air conditioner according to an embodiment of the present invention includes: a housing assembly 10, a heat exchange and air supply assembly, and a radar device 20.

[0039] The housing assembly 10 has an air inlet 110 and an air outlet 111. Airflow enters the housing through the air inlet 110 and exits through the air outlet 111. The housing assembly 10 serves to prevent dust and protect the internal components. The air inlet 110 is used to introduce indoor or outdoor air into the housing assembly 10, and the air outlet 111 is used to exhaust the treated air into the room.

[0040] For example, the air conditioner can be a split-type wall-mounted air conditioner, which includes an indoor unit 100 and an outdoor unit. The indoor unit 100 includes the aforementioned casing assembly 10, heat exchange and air supply assembly, and radar device 20. The air inlet 110 can be located at the top of the casing assembly 10, and the air outlet 111 can be located at the lower front part of the casing assembly 10.

[0041] The heat exchange and air supply assembly is located inside the housing assembly 10. This assembly heats or cools the air supplied through the air inlet 110 and discharges it through the air outlet 111. For example, air enters the housing assembly 10 through the air inlet 110, exchanges heat with the heat exchange and air supply assembly, and is then discharged into the room through the air outlet 111, thus regulating the indoor temperature. The heat exchange and air supply assembly may include a heat exchanger component and a fan component. The heat exchanger component may be located between the fan component and the air inlet 110. When the fan component is working, it drives air to enter the housing assembly 10 through the air inlet 110, exchanges heat with the heat exchanger component, flows through the fan component, and is then discharged into the room through the air outlet 111.

[0042] The radar device 20 is mounted on the housing assembly 10 and located at the bottom of the housing assembly 10.

[0043] The radar signal emitted and received by radar device 20 can be electromagnetic waves. When the radar signal emitted by radar device 20 encounters a human body, it will be reflected back and received by radar device 20. By identifying the reflected radar signal, the distance and direction of the human body relative to the air conditioner can be determined. For example, when radar device 20 detects that a human body is in front of air outlet 111, the air conditioner automatically reduces the fan speed or changes the airflow direction to avoid discomfort caused by direct airflow from the air conditioner. When radar device 20 detects that a human body is at a distance from the air conditioner, the air conditioner automatically increases the fan speed to increase the airflow velocity and make the indoor airflow circulate quickly, achieving the purpose of rapid cooling or heating.

[0044] Mounting the radar device 20 at the bottom of the housing assembly 10 reduces the obstruction of radar signals by the air conditioner, particularly reducing obstruction of signal detection in the space below the air conditioner. Because the radar device 20 is mounted at the bottom of the housing assembly 10, its emitted radar signal can cover the space below, in front of, and below the air conditioner, as well as the space to its left and / or right. This increases the coverage area where the radar signal can identify people, thus increasing the effective detection range of the radar device 20. This improves the accuracy and precision of the air conditioner's intelligent adjustment based on radar detection, ultimately enhancing the overall performance of the air conditioner.

[0045] For example, the air conditioner can be a wall-mounted air conditioner, installed on the wall of the room at a height higher than the average height of a person. By placing the radar device 20 at the bottom of the housing assembly 10, a person can be detected by the signal emitted by the radar device 20 when they are close to the air conditioner or in a corner of the room, reducing the blind spot of the radar device 20 and thus increasing the effective detection range of the radar device 20.

[0046] According to the embodiment of the present invention, by installing the radar device 20 at the bottom of the housing assembly 10, the air conditioner can reduce the obstruction of radar signals by the air conditioner, especially the obstruction of spatial signal detection located below the air conditioner, which can increase the coverage area of ​​the radar signal that can identify the human body, that is, increase the effective detection range of the radar device 20, which is beneficial to improving the overall performance of the air conditioner.

[0047] refer to Figure 2According to some embodiments of this utility model, the radar emitting surface 211 faces downwards and tilts upwards in the direction from back to front. For example, if the radar emitting surface 211 is parallel to the horizontal direction, it is difficult to detect people far from the air conditioner; if the emitting surface of the radar device 20 is parallel to the vertical direction, it is difficult to detect people close to the air conditioner, easily creating a detection blind zone. By making the radar emitting surface 211 face downwards and tilt upwards in the direction from back to front, the radar device 20 can easily detect people close to the air conditioner and also detect people far from the air conditioner, reducing the detection blind zone of the radar device 20 and further increasing the effective detection range of the radar device 20.

[0048] refer to Figure 7 According to some embodiments of the present invention, the angle between the radar emitting surface 211 and the horizontal plane is in the range of 10° to 60°.

[0049] For example, the angle between the radar emitting surface 211 and the horizontal plane can be α, which can be 10°, 20°, 30°, 40°, 50°, 60°, etc. By making the angle between the radar emitting surface 211 and the horizontal plane range from 10° to 60°, the radar signal of the radar device 20 can cover a larger area to identify the human body.

[0050] refer to Figure 4 According to some embodiments of the present invention, the housing assembly 10 includes a mounting portion 13 for mounting a radar device 20. The radar device 20 can be detachably connected to the mounting portion 13, thereby facilitating the assembly and disassembly of the radar device 20, and thus simplifying its maintenance and replacement. For example, the radar device 20 is snap-fitted to the mounting portion 13. By providing a mounting portion 13 on the housing assembly 10 and snap-fitting it to the radar device 20, it is easy to install the radar device 20 onto the housing assembly 10 and also easy to remove the radar device 20 from the housing assembly 10 without the need for additional screws. This simplifies the assembly between the radar device 20 and the housing assembly 10 and reduces the difficulty of disassembly when repairing or replacing the radar device 20.

[0051] According to some embodiments of this utility model, the radar device 20 is installed onto the mounting portion 13 from front to back. This facilitates the installation and removal of the radar device 20. For example, when the air conditioner is a wall-mounted air conditioner, if the radar device 20 is installed onto the mounting portion 13 from back to front, the radar device 20 will be installed from the side closest to the wall, which may easily cause interference between the radar device 20 and the wall, increasing the difficulty of installing the radar device 20. By installing the radar device 20 from front to back onto the mounting portion 13, it is easier to install the radar device 20 onto or remove it from the mounting portion 13.

[0052] refer to Figure 4 According to some embodiments of this utility model, a buckle 201 is provided on the rear side of the radar device 20, and buckles 202 are provided on both the left and right sides of the radar device 20, with the buckles 202 located at the front end of the radar device 20. The mounting part 13 is provided with a slot 131 and a locking hole 132. The buckle 201 is inserted rearward into the slot 131, and the buckle 202 is engaged in the locking hole 132. During the process of installing the radar device 20 from front to back onto the mounting part 13, the buckle 201 on the radar device 20 is inserted rearward into the slot 131 on the mounting part 13, and the buckle 202 on the radar device 20 can be engaged upward into the locking hole 132 on the mounting part 13. By simultaneously providing a buckle 201 and a snap fastener 202 on the radar device 20, inserting the buckle 201 of the radar device 20 into the slot 131 of the mounting part 13, and snapping the snap fastener 202 of the radar device 20 into the snap hole 132 of the mounting part 13, the firmness of the radar device 20 installed on the mounting part 13 can be increased. By placing the buckle 201 on the rear side of the radar device 20 and the snap fastener 202 on the front side of the radar device 20, when the radar device 20 is installed on the mounting part 13 from front to back, the buckle 201 of the radar device 20 is more easily inserted into the slot 131 of the mounting part 13, which facilitates the installation of the radar device 20.

[0053] refer to Figure 1 According to some embodiments of this utility model, the radar device 20 is located in the middle of the housing assembly 10 in the left-right direction. For example, if the radar device 20 is located off-center from one side of the housing assembly 10 in the left-right direction, it is easy to waste the detection range of the radar device 20 on that side and also to increase the blind spot of the radar device 20 on the other side. By installing the radar device 20 in the middle of the housing assembly 10, the radar signal of the radar device 20 can effectively cover the space on both sides of the air conditioner, thereby increasing the effective detection range of the radar device 20.

[0054] refer to Figures 5-7According to some embodiments of the present invention, the radar device 20 includes a radar module 21 and a radar dome 24. The radar module 21 is mounted on the radar dome 24 and has a radar emitting surface 211. The radar dome 24 protects the radar module 21, for example, preventing indoor insects from entering and damaging it. The housing assembly 10 includes a mounting portion 13 for mounting the radar device 20. The radar dome 24 is mounted on the outside of the mounting portion 13, and the radar dome 24 and the mounting portion 13 together define a receiving cavity 25. At least a portion of the radar module 21 is received within the receiving cavity 25. For example, at least a portion of the radar module 21 may be received within the receiving cavity 25; all parts of the radar module 21 may be received within the receiving cavity 25, or only a portion of the radar module 21 may be received within the receiving cavity 25. By accommodating at least a portion of the radar module 21 within the housing cavity 25, the space occupied by the radar module 21 inside the radar dome 24 can be saved, thereby reducing the design size of the radar dome 24, making the overall structure of the air conditioner more compact, and also saving the manufacturing cost of the radar dome 24.

[0055] Alternatively, the radome 24 can be made of plastic.

[0056] refer to Figures 5-7 According to some embodiments of the present invention, the radar dome 24 includes a first dome 241, a radar module 21 is mounted on the first dome 241, a radar emitting surface 211 is disposed opposite to the first dome 241, the surface of the first dome 241 facing the radar emitting surface 211 is a first surface 242, the first surface 242 is a plane and the angle between the first surface 242 and the radar emitting surface 211 is in the range of 0° to 5°.

[0057] For example, the angle between the first surface 242 and the radar emitting surface 211 can be 0°, 0.5°, 1°, 1.5°, 2°, 2.5°, 3°, 3.5°, 4°, 4.5°, 5°, etc. By making the first surface 242 planar and the angle between the first surface 242 and the radar emitting surface 211 in the range of 0° to 5°, the side of the first cover 241 facing the radar emitting surface 211 can be arranged substantially parallel to the radar emitting surface 211. This makes it easier for the radar signals transmitted and received by the radar device 20 to penetrate the first cover 241, reducing the reflection and scattering of the radar signals transmitted and received by the radar emitting surface 211 when passing through the first cover 241. This makes the radar signal less prone to attenuation and helps to increase the effective detection range of the radar device 20.

[0058] refer to Figure 7According to some embodiments of this utility model, the wall thickness of the first cover 241 is uniform. If the wall thickness of the first cover 241 is not uniform, the radar signals transmitted and received by the radar transmitting surface 211 are easily reflected and scattered when passing through the first cover 241, which aggravates the attenuation of the radar signal. By making the wall thickness of the first cover 241 uniform, the radar signals transmitted and received by the radar device 20 can more easily penetrate the first cover 241, and the radar signal is less prone to attenuation, which is beneficial to increasing the effective detection range of the radar device 20.

[0059] refer to Figures 7-8 According to some embodiments of this utility model, the radome 24 includes a first cover portion 241, a radar module 21 mounted on the first cover portion 241, a radar emitting surface 211 disposed opposite to the first cover portion 241, and a second surface 243 of the first cover portion 241 facing away from the radar emitting surface 211. The second surface 243 is provided with a decorative plate 26, and both the decorative plate 26 and the radome 24 are independently molded parts. For example, the decorative plate 26 and the radome 24 can be separately injection molded and then assembled, facilitating the processing of the decorative plate 26 and the radome 24 and saving manufacturing costs. By making the decorative plate 26 and the radome 24 independently molded parts, the materials and / or colors of the decorative plate 26 and the radome 24 can be different, making the selection of the decorative plate 26 more flexible. By providing a decorative plate 26 on the second surface 243, an installation error prevention effect can be achieved, preventing incorrect installation direction of the radome 24 from causing incorrect orientation of the radar emitting surface 211. Furthermore, it can make the transmitting surface of the radar device 20 more conspicuous.

[0060] Optionally, the decorative panel 26 can be attached to the second surface 243 of the radome 24 with double-sided adhesive, making it easy to install and fix the decorative panel 26 on the radome 24.

[0061] refer to Figure 7In some embodiments of this utility model, the radar dome 24 includes a first dome 241 and a second dome 244. The radar module 21 is mounted on the first dome 241, and the radar emitting surface 211 is disposed opposite to the first dome 241. The first dome 241 extends upward at an angle from back to front. The second dome 244 is connected to the lower side of the first dome 241 and extends backward. For example, the second dome 244 can extend horizontally. The second dome 244 is connected to the rear side of the first dome 241 and is disposed at an angle to the first dome 241. The angle between the second dome 244 and the horizontal plane is smaller than the angle between the first dome 241 and the horizontal plane. By making the first cover 241 extend upward at an angle from back to front, and the second cover 244 is connected to the lower side of the first cover 241 and extends backward, if condensate from the air conditioner drips into the radar cover 24, the condensate in the radar cover 24 is more likely to flow to the second cover 244 of the radar cover 24 under the action of gravity because the second cover 244 is lower in height than the first cover 241. This can reduce the risk of condensate accumulating in the first cover 241 and causing the radar module 21 to malfunction.

[0062] For example, both the first cover 241 and the second cover 244 can be flat, which simplifies the structure of the first cover 241 and the second cover 244 and facilitates their manufacturing. Furthermore, by making the first cover 241 flat, the radar signals transmitted and received by the radar device 20 can more easily penetrate the first cover 241, and the radar signals are less prone to attenuation, which helps to increase the effective detection range of the radar device 20.

[0063] refer to Figure 4 According to some embodiments of this utility model, a clearance opening 134 is formed on the mounting part 13, and a portion of the radar module 21 is accommodated in the clearance opening 134 or a portion of the radar module 21 extends into the housing assembly 10 through the clearance opening 134. By accommodating a portion of the radar module 21 in the clearance opening 134 or extending a portion of the radar module 21 into the housing assembly 10 through the clearance opening 134, the internal space of the housing assembly 10 can be effectively utilized, saving the internal space of the radar cover 24 occupied by the radar module 21, thereby reducing the design size of the radar cover 24 and making the overall structure of the air conditioner more compact.

[0064] refer to Figure 4 According to some embodiments of the present invention, a screw seat 133 is provided on the inner side of the mounting part 13, and the clearance opening 134 is at least partially offset from the screw seat 133.

[0065] The screw seat 133 provided on the inner side of the mounting part 13 is used for connecting or installing other components of the air conditioner. For example, the screw seat 133 can be used for connecting the components of the housing assembly 10. When the components of the housing assembly 10 are connected by screws at this position, the screws can be inserted into the screw seat 133.

[0066] The clearance opening 134 and the screw seat 133 are at least partially offset. This offset can be complete, or a portion of the clearance opening 134 can be offset from a portion of the screw seat 133. By offsetting the clearance opening 134 from the screw seat 133, interference between the radar module 21 and the screw seat 133 can be reduced, facilitating the insertion of a portion of the radar module 21 into the housing assembly 10 through the clearance opening 134, thereby saving installation space for the radar module 21.

[0067] According to some embodiments of this utility model, the radar module 21 is located in the center or off-center of the radar dome 24. For example, in the left-right direction, the radar module 21 can be located in the center or off-center of the radar dome 24. This allows for flexible placement of the radar module 21 within the radar dome 24, allowing it to be positioned in the center or off-center depending on the actual installation situation. For example, placing the radar module 21 off-center avoids some structures on the housing assembly 10, such as the screw seat 133, thus preventing interference and facilitating wiring. Furthermore, this also allows the entire radar device 20 to be centered within the housing assembly 10 visually.

[0068] For example, when at least a portion of the radar module 21 is housed in the receiving cavity 25, and the radar module 21 does not interfere with the components inside the housing assembly 10, the radar module 21 can be positioned in the middle of the radar dome 24 to save space inside the radar dome 24; when the radar module 21 interferes with the components inside the housing assembly 10, the radar module 21 can also be positioned off to one side of the radar dome 24, so that the radar module 21 is staggered from the components inside the housing assembly 10, thereby improving the space utilization rate inside the housing assembly 10.

[0069] refer to Figure 5According to some embodiments of the present invention, the radar dome 24 is provided with a mounting position 245 and a first limiting structure 27. The radar device 20 is located at the mounting position 245. The first limiting structure 27 includes a plurality of first limiting buckles 271 arranged at intervals along the circumference of the mounting position 245. Each first limiting buckle 271 includes a first limiting part 272 and a first pressing part 273 connected together. One end of the first limiting part 272 is fixed to the radar dome 24, and the first pressing part 273 is connected to the other end of the first limiting part 272. The first limiting part 272 is located on the outer periphery of the radar module 21, and the first pressing part 273 abuts against the side of the radar module 21 opposite to the mounting position 245. By providing mounting positions 245 on the radome 24, the radar module 21 can be accurately installed in the corresponding position when it is installed on the radome 24, and the mounting positions 245 can also fix the radar module 21. Furthermore, by providing multiple first limiting buckles 271 at circumferential intervals along the mounting positions 245, the stability of the installation between the radar module 21 and the radome 24 can be further increased. Among them, the first limiting part 272 can limit the radar module 21 in a direction parallel to the radar emitting surface 211 to prevent the radar module 21 from falling off the mounting position 245, and the first pressing part 273 can press and fix the radar module 21 in a direction perpendicular to the radar emitting surface 211. The first pressing part 273 and the first limiting part 272 cooperate to increase the stability of the installation between the radar module 21 and the radome 24.

[0070] refer to Figure 5 According to some embodiments of this utility model, the first limiting structure 27 further includes a limiting rib 274, which extends circumferentially along the mounting position 245 and is located on the outer periphery of the radar module 21. For example, the limiting rib 274 can extend continuously along the outer periphery of the radar module 21 to limit its movement, or it can extend discontinuously along the outer periphery of the radar module 21 to limit its movement. By providing a limiting rib 274 on the outer periphery of the radar module 21, the radar module 21 can be prevented from shaking, thus enhancing the stability of the radar module 21 mounted on the radar cover 24.

[0071] refer to Figures 6-9According to some embodiments of the present invention, the radar dome 24 includes a first dome 241, and the radar module 21 includes a radar mount 22 and a radar circuit board 23. The radar mount 22 is mounted on the first dome 241, and a mounting groove 221 is formed on the side of the radar mount 22 facing the first dome 241. The radar circuit board 23 is accommodated in the mounting groove 221, and the radar circuit board 23 has a radar emitting surface 211, which is disposed opposite to the first dome 241. By forming a mounting groove 221 on the side of the radar mount 22 facing the first dome 241, the radar circuit board 23 can be accurately installed in the corresponding position when it is installed on the radar mount 22. The mounting groove 221 can also limit the position of the radar circuit board 23. Furthermore, accommodating the radar circuit board 23 in the radar mount 22 can also protect the radar circuit board 23. In addition, by forming a mounting groove 221 on the side of the radar mount 22 facing the first cover 241, the attenuation of the radar signal emitted by the radar emitting surface 211 of the radar circuit board 23 to the outside of the air conditioner can be reduced.

[0072] For example, both the radome 24 and the radar mount 22 are made of plastic.

[0073] Both the radar mount 22 and the radar cover 24 are independently molded parts. For example, the radar mount 22 and the radar cover 24 can be injection molded as a single piece. By making the radar mount 22 and the radar cover 24 independently molded parts, it is convenient to install the radar circuit board 23 onto the radar mount 22, and then install the radar mount 22 with the radar circuit board 23 onto the radar cover 24.

[0074] For example, in some embodiments, the first cover 241 extends upward at an angle from back to front, and a mounting groove 221 is formed on the side of the radar mount 22 facing the first cover 241, that is, the side of the radar mount 22 facing the first cover 241 faces the lower front of the air conditioner. When condensation is generated inside the air conditioner, the condensation drips onto the side of the radar mount 22 away from the first cover 241. Under the action of gravity, the condensation slides off the side of the radar mount 22 away from the first cover 241, which can prevent condensation from entering the radar circuit board 23 and reduce the risk of the radar circuit board 23 malfunctioning due to condensation.

[0075] refer to Figure 9According to some embodiments of this utility model, the radar base 22 is provided with a second limiting structure 28. The second limiting structure 28 includes a plurality of second limiting buckles 281 spaced apart along the circumference of the radar circuit board 23. Each second limiting buckle 281 includes a second pressing part 282, which abuts against the side of the radar circuit board 23 facing the first cover 241. The second pressing part 282 can press and fix the radar circuit board 23 in a direction perpendicular to the radar circuit board 23. By providing a plurality of second limiting buckles 281 around the circumference of the radar circuit board 23, the radar circuit board 23 can be prevented from detaching from the radar base 22, increasing the stability of the installation between the radar circuit board 23 and the radar base 22.

[0076] refer to Figure 9 According to some embodiments of this utility model, the radar base 22 is provided with a positioning post 222, and the radar circuit board 23 is provided with a positioning hole 231, into which the positioning post 222 is inserted. For example, the radar base 22 may have one or more positioning posts 222; the radar circuit board 23 may have one or more positioning holes 231 that cooperate with the positioning post 222. When the radar circuit board 23 is installed onto the radar base 22, the positioning post 222 can serve as a guide. By inserting the positioning post 222 into the positioning hole 231, it is easy to install the radar circuit board 23 onto the radar base 22. The positioning post 222 can also serve as a foolproof mechanism, preventing the radar emitting surface 211 from being incorrectly oriented due to incorrect installation direction of the radar circuit board 23. After the radar circuit board 23 is installed, the positioning post 222 can also increase the stability of the radar circuit board 23 installation.

[0077] refer to Figure 9 According to some embodiments of this utility model, the radar circuit board 23 is connected to a radar wiring harness, and the radar base 22 is provided with a wiring outlet 223 for the radar wiring harness to exit. The radar wiring harness is used to connect the radar circuit board 23 to a device outside the radar device 20. By providing a wiring outlet 223 on the radar base 22, the radar wiring harness can exit from the outlet 223, facilitating unified exit of the radar wiring harness, preventing interference between the radar wiring harness and the radar base 22, and facilitating the assembly of the radar circuit board 23 and the radar base 22.

[0078] refer to Figures 4-6According to some embodiments of this utility model, a first wiring structure 29 is provided on the side of the radar mount 22 opposite to the first cover portion 241. The first wiring structure 29 defines a wiring path for the radar harness wiring. For example, the first wiring structure 29 may include multiple first wiring clips 291 and / or multiple limiting posts 292, which define the wiring path for the radar harness wiring. The first wiring structure 29 may include multiple first wiring clips 291, multiple limiting posts 292, or both. By providing the first wiring structure 29 for the radar harness wiring, the radar harness can be routed along the defined wiring path, reducing interference between the radar harness and components inside the air conditioner.

[0079] refer to Figure 4 According to some embodiments of the present invention, a clearance opening 134 is formed on the mounting portion 13, and the first wiring structure 29 is accommodated in the clearance opening 134 or extends into the housing assembly 10 through the clearance opening 134. By forming a clearance opening 134 on the mounting portion 13, the first wiring structure 29 can be accommodated in the clearance opening 134 or extend into the housing assembly 10 through the clearance opening 134. This effectively utilizes the internal space of the housing assembly 10, saves the internal space of the radar dome 24 occupied by the radar module 21, thereby reducing the design size of the radar dome 24, making the overall structure of the air conditioner more compact, and also facilitating the continued routing of the radar harness within the housing assembly 10, reducing interference between the radar harness and the housing assembly 10.

[0080] refer to Figure 3 According to some embodiments of this utility model, the housing assembly 10 includes a face frame 11, on which an air inlet 110 and an air outlet 111 are formed. Airflow enters the housing through the air inlet 110, is processed by the heat exchange and air supply assembly, and is then discharged through the air outlet 111. The radar device 20 is mounted on the bottom of the face frame 11. For example, the face frame 11 may include the aforementioned mounting portion 13. By mounting the radar device 20 on the face frame 11, the obstruction of the radar signal of the radar device 20 by the volute plate 12 and housing assembly 10 can be reduced. When the angle range for receiving and transmitting signals by the radar device 20 is fixed, the effect of receiving and transmitting signals by the radar device 20 is improved, thereby increasing the effective detection range of the radar device 20.

[0081] According to some embodiments of this utility model, the air conditioner includes an electrical control box, which is disposed within the housing assembly 10 and is used to control the operation of the air conditioner. The radar device 20 is connected to the electrical control box via a radar harness, and a second wiring structure 14 for routing the radar harness is provided on the faceplate 11.

[0082] refer to Figure 10 The faceplate 11 is provided with a second routing structure 14 for radar wire harness routing. The second routing structure 14 may include multiple second routing clips 141 and / or multiple limiting posts 292, which define the routing path for the radar wire harness. The second routing structure 14 may include multiple second routing clips 141, multiple limiting posts 292, or both. By providing the second routing structure 14 for radar wire harness routing, the radar wire harness can be routed along the defined routing path, reducing interference between the radar wire harness and components inside the air conditioner.

[0083] refer to Figure 10 According to some embodiments of the present invention, the radar device 20 is installed on the base plate 112 of the face frame 11, the base plate 112 is located at the bottom of the face frame 11, the second wiring structure 14 includes a second wiring buckle 141, the second wiring buckle 141 is disposed on the base plate 112 and the second wiring buckle 141 is located on the inner side of the face frame 11, the housing assembly 10 includes a volute plate 12, the volute plate 12 is connected to the upper side of the base plate 112, and the second wiring buckle 141 is located between the bottom surface of the volute plate 12 and the base plate 112.

[0084] For example, the radar harness is led out from the outlet 223 of the radar mount 22, and routed through the routing path defined by the first routing buckle 291 and the limiting post 292 to the inner side of the air conditioner base plate 112. Then, it is routed along the left-right direction of the air conditioner through the second routing buckle 141 to the bottom of the air conditioner side plate 113 and continues to route. By providing the second routing buckle 141 on the inner side of the face frame 11 and on the base plate 112, and by positioning the second routing buckle 141 between the bottom surface of the volute plate 12 and the base plate 112, the radar harness can be routed on the inner side of the face frame 11 when it is routed along the base plate 112 of the face frame 11. This makes full use of the space between the bottom surface of the volute plate 12 and the base plate 112 of the face frame 11, and also helps the radar harness to stay close to the base plate 112 of the face frame 11 during the routing process, reducing interference between the radar harness and other structures inside the housing assembly 10.

[0085] refer to Figure 10 According to some embodiments of the present invention, the electrical control box is located above the radar device 20, and the second wiring structure 14 includes a third wiring buckle 142, which is disposed on the side plate 113 of the face frame 11.

[0086] For example, the radar harness is led out from the outlet 223 of the radar mount 22, and routed through the routing path defined by the first wiring clip 291 and the limiting post 292 to the inner side of the air conditioner base plate 112. Then, it is routed along the left-right direction of the air conditioner through the second wiring clip 141 to the bottom of the air conditioner side plate 113. After that, it is routed upward along the side plate 113 of the air conditioner through the third wiring clip 142, and finally connected to the electrical control box. By providing the third wiring clip 142 on the side plate 113 of the face frame 11, it is beneficial for the radar harness to stay close to the side plate 113 of the face frame 11 during the routing process. The radar beam runs along the bottom plate 112 of the face frame 11 and then continues along the side plate 113 of the face frame 11 to the top of the face frame 11, and extends to the location of the electronic control box and connects with the electronic control box. This allows the radar beam to run along the face frame 11, which can reduce the space occupied by other parts and reduce interference with other structures in the housing assembly 10.

[0087] refer to Figure 10 According to some embodiments of the present invention, the third wiring buckle 142 is located on the inner side of the side plate 113.

[0088] For example, the radar harness is led out from the outlet 223 of the radar mount 22, and routed through the wiring path defined by the first wiring clip 291 and the limiting post 292 to the inside of the air conditioner base plate 112. Then, it is routed through the second wiring clip 141 along the left-right direction of the air conditioner to the bottom of the air conditioner side plate 113. After that, it is routed upward along the inner surface of the air conditioner side plate 113 through the third wiring clip 142, and finally connected to the electrical control box. By placing the third wiring clip 142 inside the side plate 113, the radar harness is routed through the third wiring clip 142, which helps the radar harness to stay close to the inner surface of the face frame 11 during the wiring process, thus avoiding exposure of the radar harness.

[0089] refer to Figure 10 According to some embodiments of the present invention, the third wiring buckle 142 protrudes outward toward the side plate 113. The side plate 113 is provided with a first wiring hole 143 and a second wiring hole 144. The first wiring hole 143 is located below the third wiring buckle 142 for routing radar wire harnesses to the outside of the side plate 113, and the second wiring hole 144 is located above the third wiring buckle 142 for routing radar wire harnesses to the inside of the side plate 113.

[0090] For example, the radar harness is led out from the outlet 223 of the radar mount 22, and is routed to the inside of the air conditioner base plate 112 through the routing path defined by the first routing buckle 291 and the limiting post 292. Then, it is routed along the left and right direction of the air conditioner through the second routing buckle 141 to the bottom of the air conditioner side plate 113. At this time, the radar harness first runs from the inside of the side plate 113 to the outside of the side plate 113 through the first wiring hole 143, then runs upward along the side plate 113 of the air conditioner through the third routing buckle 142, and then runs from the outside of the side plate 113 to the inside of the side plate 113 through the second wiring hole 144, and finally connects to the electrical control box. By protruding the third wiring clip 142 toward the outside of the side plate 113, the radar wire harness can be routed on the outside of the air conditioner side plate 113 through the first wiring hole 143 and the second wiring hole 144. This can save space inside the face frame 11, which is beneficial to reduce the size of the face frame 11 in the left and right direction, thereby reducing the size of the air conditioner in the left and right direction. It can also better avoid interference between the radar wire harness and other components inside the face frame 11.
