Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically providing a chassis assembly and a portable air conditioner. Background Technology

[0002] Currently, both wall-mounted and floor-standing air conditioners require fixed installation in a limited location and cannot be moved. Therefore, portable air conditioners have emerged. A portable air conditioner mainly consists of a casing, an indoor airflow assembly, and an outdoor airflow assembly. Both the indoor and outdoor airflow assemblies are housed within the casing. The casing has indoor air inlets and outlets corresponding to the indoor airflow assembly, and similarly, outdoor air inlets and outlets corresponding to the outdoor airflow assembly. Due to their small size, portable air conditioners can be moved to different locations or rooms to regulate the air temperature in those locations or rooms.

[0003] In portable air conditioners using related technologies, the chassis typically has a power cord outlet, usually horizontally positioned so that the power cord exits horizontally. This necessitates a corresponding cutout in the back panel of the air conditioner's casing to accommodate the power cord. However, the higher the power cord outlet, the larger the cutout in the back panel needs to be from bottom to top, affecting the panel's strength. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem of high wire slot opening.

[0005] In a first aspect, the present invention provides a chassis assembly, comprising: a chassis body arranged horizontally; a peripheral portion extending upward around the chassis body and enclosing an installation space; and a cable guide portion formed in the peripheral portion and extending toward the installation space, wherein the cable guide portion is provided with a cable guide groove extending along the thickness direction of the peripheral portion, the bottom wall of the cable guide groove is inclined downward from the inside to the outside, and the cable guide groove is configured to allow a power cable to extend along the cable guide groove to the outside of the installation space.

[0006] By adopting the above technical solution, and by arranging the bottom wall of the cable tray to extend downwards from the inside out, the power cable can extend downwards along the cable tray outside the installation space. This lowers the position of the cable tray opening outside the installation space, allowing for the creation of a low-height clearance groove on the housing corresponding to the bottom of the cable tray. This reduces the size of the clearance groove opening on the housing, maintaining the continuity of the housing and improving its overall structural strength.

[0007] In an optional embodiment of the chassis assembly described above, the angle between the bottom groove wall and the upper surface of the chassis body is greater than or equal to 20° and less than or equal to 60°.

[0008] By limiting the angle between the bottom groove wall and the upper surface of the chassis body to a range of greater than or equal to 20° and less than or equal to 60°, it is possible to avoid the bottom groove wall being too flat, which would affect the strength of the corresponding cover, and to avoid the bottom groove wall being too steep, which would affect the fixation of the power cord.

[0009] In an optional embodiment of the chassis assembly described above, the bottom wall of the cable tray and the side wall are connected by an arc transition.

[0010] By using the arc-shaped connection between the bottom and side walls of the cable tray, the shape of the cable tray can be matched with the shape of the power cable as much as possible, ensuring the installation effect of the power cable.

[0011] In an optional embodiment of the chassis assembly described above, the assembly further includes: a mounting platform connected to the cable tray and disposed in the mounting space, the mounting platform having an inclined platform extending in the same direction as the bottom wall of the cable tray; two fixing posts disposed on both sides of the inclined platform, the fixing posts extending in a direction perpendicular to the inclined platform; and a pressure plate, the two ends of the pressure plate being fixedly connected to the two fixing posts respectively by connectors, so that the power cord can be clamped between the pressure plate and the inclined platform.

[0012] By using the mounting platform, fixing posts, and pressure plates, the power cord can be further secured within the installation space, preventing it from shifting.

[0013] In an optional embodiment of the chassis assembly described above, the pressure plate is bent into a groove that matches the shape of the power cord.

[0014] By bending the pressure plate to form a groove that matches the shape of the power cord, wear on the power cord can be reduced, the power cord can be effectively fixed, and the power cord can be prevented from shaking.

[0015] In an optional embodiment of the chassis assembly described above, the fixing post has screw holes extending along its own length, and the two ends of the pressure plate have through holes that match the two screw holes; the connector is a screw.

[0016] The screw holes, through holes, and screws work together to secure the power cord while facilitating disassembly and replacement.

[0017] In an optional embodiment of the chassis assembly described above, a first reinforcing rib is further included, connected between the fixed column and the mounting platform.

[0018] By setting the first reinforcing rib, the structural strength and stability of the mounting platform can be effectively improved.

[0019] In an optional embodiment of the chassis assembly described above, a enclosure frame is further included, which is arranged around the outer periphery of the mounting platform and the fixed column in the mounting space and connected to the end face of the wire passage portion. The enclosure frame includes a positioning plate arranged opposite to the wire passage portion, and the positioning plate is provided with a positioning groove that matches the wire passage groove.

[0020] The enclosure frame can protect the fixed posts. At the same time, the positioning plate is equipped with a positioning groove that matches the cable tray, which facilitates the routing of power cables.

[0021] In an optional embodiment of the chassis assembly described above, the assembly further includes: a second reinforcing rib connected between the fixed post and the guide wire portion; and a third reinforcing rib connected between the fixed post and the positioning plate; wherein the second reinforcing rib and the third reinforcing rib are located on the same diameter line of the fixed post.

[0022] The addition of second and third reinforcing ribs helps improve the stability of the fixing column, thereby enhancing the stability of the power cord fixing.

[0023] Secondly, this utility model provides a portable air conditioner, including: a chassis assembly as described above; and a cover, the cover covering the upper part of the chassis body and abutting against the outer wall surface of the peripheral portion, wherein the bottom edge of the cover is provided with a relief groove with an opening facing downward and matching the cable groove.

[0024] With the above technical solution, the cover covers the top of the chassis body and abuts against the outer wall of the periphery. By arranging the bottom wall of the cable tray downwards from the inside out, the power cable can extend downwards along the cable tray outside the installation space. In this way, a clearance groove can be opened on the cover corresponding to the bottom end of the cable tray as much as possible, thereby reducing the opening size of the clearance groove on the cover, maintaining the continuity of the cover, and improving the overall structural strength of the cover.

[0039] Firstly, combining Figures 1 to 5 As shown, this utility model provides a chassis assembly 10, including a chassis body 100, a peripheral portion 200, and a line-passing portion 300.

[0040] The chassis body 100 is arranged horizontally. The peripheral portion 200 extends upward around the chassis body 100 and encloses an installation space. A cable guide portion 300 is formed in the peripheral portion 200 and extends toward the installation space. The cable guide portion 300 has a cable guide groove 310 extending along the thickness direction of the peripheral portion 200. The bottom wall 311 of the cable guide groove 310 is arranged downward from the inside to the outside, and the cable guide groove 310 is configured to allow the power cable to extend along the cable guide groove 310 to the outside of the installation space.

[0041] Optionally, the chassis assembly 10 is used in portable air conditioners or other household appliances. When the portable air conditioner or other household appliance is in use, it is usually placed on a level surface or a level shelf. Therefore, the chassis body 100 is arranged horizontally to ensure the stability of the portable air conditioner or other household appliance.

[0042] Optionally, a peripheral portion 200 is provided around the chassis body 100 in the circumferential direction, and the peripheral portion 200 extends upward. The peripheral portion 200 defines an installation space within its inner perimeter. The peripheral portion 200 facilitates connection with the housing of the portable air conditioner, increasing the contact area.

[0043] Optionally, a cross-line portion 300 is formed on a portion of the peripheral portion 200.

[0044] Optionally, the peripheral portion 200 and the guide portion 300 are integrally formed, and also integrally formed with the chassis body. This helps to improve the overall stability and structural strength of the chassis assembly 10.

[0045] Optionally, by providing a cable tray 310 extending along the thickness direction of the peripheral portion 200 in the cable tray 300, it is beneficial to guide the power cable to extend out of the installation space along the extension direction of the cable tray 310, that is, it is beneficial to the cable management and wiring of the power cable.

[0046] Optionally, the bottom wall 311 of the cable tray 310 is arranged to slope downwards from the inside out. In this way, the opening on the side of the cable tray 310 away from the installation space can be located as low as possible, thereby allowing the bottom end of the cover that abuts against the peripheral portion 200 to be provided with a lower clearance groove, which in turn makes the opening of the clearance groove smaller, so as to maintain the continuity of the cover and improve the overall structural strength of the cover.

[0047] In this design, the bottom wall 311 of the cable tray 310 is arranged downwards from the inside to the outside. Here, "from the inside to the outside" refers to the direction from inside the installation space to outside the installation space.

[0048] Specifically, the top of the cable tray 310 is open, and the clearance groove is located at the bottom of the housing, also open at the bottom. Thus, after the housing is installed, the opening of the cable tray 310 aligns with the opening of the clearance groove, facilitating the passage of the power cable.

[0049] In addition, by arranging the bottom wall 311 of the cable tray 310 at an angle, it is beneficial for condensation generated in the installation space or on the outer surface of the power cord to flow outward, preventing condensation from entering the installation space, thereby preventing other metal components from rusting and extending their service life.

[0050] When the above technical solution is adopted, by setting the bottom wall 311 of the cable tray 310 to extend downward from the inside out, the power cable can extend downward along the cable tray outside the installation space. In this way, the slot position of the cable tray 310 outside the installation space is relatively low, and a low clearance groove can be opened at the bottom end of the cover corresponding to the cable tray 310 on the cover that matches the chassis assembly 10. This reduces the size of the clearance groove opening on the cover, thereby maintaining the continuity of the cover and improving the overall structural strength of the cover.

[0051] In an optional embodiment of the chassis assembly 10 described above, the angle between the bottom groove wall 311 and the upper surface of the chassis body is greater than or equal to 20° and less than or equal to 60°.

[0052] By limiting the angle between the bottom groove wall 311 and the upper surface of the chassis body to a range of greater than or equal to 20° and less than or equal to 60°, it is possible to avoid the bottom groove wall 311 being too gentle and affecting the strength of the corresponding cover 20, and to avoid the bottom groove wall 311 being too steep and affecting the fixation of the power cord.

[0053] Preferably, the angle between the bottom groove wall 311 and the upper surface of the chassis body is 40°.

[0054] In an optional embodiment of the chassis assembly 10 described above, the bottom wall 311 of the through groove 310 is connected to the side wall 312 in an arc transition.

[0055] By connecting the bottom wall 311 and the side wall 312 of the cable tray 310 in an arc shape, the shape of the cable tray 310 can be matched with the shape of the power cable as much as possible, ensuring the installation effect of the power cable.

[0056] Alternatively, the bottom wall 311 of the cable tray 310 is connected to the side wall 312 at a right angle.

[0057] Optionally, the cable tray 310 includes two opposing side walls 312, the distance between the ends of the two side walls 312 away from the bottom wall 311 being less than the distance between the ends of the two side walls connected to the bottom wall 311. This allows the power cable to be clamped to prevent it from coming loose.

[0058] In an optional embodiment of the chassis assembly 10 described above, a mounting platform 400, fixing posts 500, and a clamping plate 600 are also included. The mounting platform 400 is connected to the cable tray 310 and arranged in the installation space. The mounting platform 400 has an inclined platform 401 extending in the same direction as the bottom wall 311 of the cable tray 310. Two fixing posts 500 are disposed on both sides of the inclined platform 401, and the fixing posts 500 extend in a direction perpendicular to the inclined platform. The two ends of the clamping plate 600 are respectively fixedly connected to the two fixing posts 500 by connectors 900, so that the power cord can be clamped between the clamping plate 600 and the inclined platform.

[0059] With the cooperation of the mounting platform 400, the fixing column 500 and the pressure plate 600, the power cord can be further fixed in the installation space to prevent the power cord from moving around.

[0060] Specifically, the fixing post 500 extends in a direction perpendicular to the inclined platform 401 to cooperate with the pressure plate 600. The inclined fixing post 500, compared to a direction perpendicular to the chassis body 100, has a longer extension length and better stability. Furthermore, the length of the fixing post 500 can be reduced within a reasonable range, ensuring sufficient space for installing the pressure plate 600 and improving the ease of installing the pressure plate 600 to secure the power cord.

[0061] Optionally, the mounting platform 400 is designed to extend the surface for power cord installation and facilitate cooperation with the fixing post 500 and the pressure plate 600 to secure the power cord. The mounting platform 400 has an inclined surface 401 extending in the same direction as the bottom wall 311 of the cable tray 310. This ensures consistency in the extension direction when the power cord is secured.

[0062] In an optional embodiment of the chassis assembly 10 described above, the pressure plate 600 is bent to form a slot 610 that matches the shape of the power cord.

[0063] By bending the pressure plate 600 into a slot 610 that matches the shape of the power cord, wear on the power cord can be reduced, the power cord can be effectively fixed, and the power cord can be prevented from shaking.

[0064] Alternatively, the slot 610 is not provided, so that the pressure plate 600 has a certain degree of elasticity, so that the shape of the pressure plate 600 can be directly changed when installing the power cord to fix the power cord between the pressure plate 600 and the mounting table 400.

[0065] In an optional embodiment of the chassis assembly 10 described above, the fixing post 500 is provided with screw holes 510 extending along its own length direction, and the pressure plate 600 is provided with through holes at both ends that match the two screw holes; the connector 900 is a screw.

[0066] The screw holes, through holes, and screws work together to secure the power cord while facilitating disassembly and replacement.

[0067] In an optional embodiment of the chassis assembly 10 described above, a first reinforcing rib 710 is also included. The first reinforcing rib 710 is connected between the fixed post 500 and the mounting platform 400.

[0068] By setting the first reinforcing rib 710, the structural strength and stability of the mounting platform 400 can be effectively improved.

[0069] Optionally, the first reinforcing rib is integrally formed with the chassis body 100. Alternatively, the first reinforcing rib is fixedly connected to the chassis body 100.

[0070] Optionally, the first reinforcing rib 710, the fixing column 500, and the mounting platform 400 are integrally formed.

[0071] Alternatively, the first reinforcing rib 710 may not be provided.

[0072] In an optional embodiment of the chassis assembly 10 described above, a enclosure frame 800 is also included. The enclosure frame 800 is arranged around the outer periphery of the mounting platform 400 and the fixing post 500 in the installation space and is connected to the end face of the wire passage portion. The enclosure frame 800 includes a positioning plate 810 arranged opposite to the wire passage portion, and the positioning plate 810 is provided with a positioning groove 811 that matches the wire passage groove 310.

[0073] The enclosure frame can protect the fixed post 500. At the same time, the positioning plate is provided with a positioning groove 811, which matches the wire channel 310 to facilitate the routing of power lines.

[0074] Optionally, the mounting platform 400 also includes a connecting platform 402 parallel to the chassis body 100, the connecting platform 402 being connected between the positioning plate 810 and the inclined platform 401.

[0075] Alternatively, no fencing frame 800 may be set.

[0076] In an optional embodiment of the chassis assembly 10 described above, a second reinforcing rib 720 and a third reinforcing rib 730 are further included. The second reinforcing rib 720 is connected between the fixing post 500 and the wiring section. The third reinforcing rib 730 is connected between the fixing post 500 and the positioning plate.

[0077] The second reinforcing rib 720 and the third reinforcing rib 730 are located on the same diameter line of the fixed column 500.

[0078] The installation of the second reinforcing rib 720 and the third reinforcing rib 730 helps to improve the stability of the fixing post 500, thereby enhancing the stability of the power cord fixing.

[0079] Alternatively, the second reinforcing rib 720 may not be provided, and / or the third reinforcing rib 730 may not be provided.

[0080] Secondly, combining Figures 1 to 7 As shown, this utility model provides a portable air conditioner, including a chassis assembly 10 and a cover 20 as described above. The cover 20 covers the upper part of the chassis body 100 and abuts against the outer wall surface of the peripheral portion 200. The bottom edge of the cover 20 is provided with a relief groove 21 with an opening facing downward and matching the cable channel 310.

[0081] With the above technical solution adopted, the cover 20 covers the top of the chassis body 100 and abuts against the outer wall surface of the peripheral portion 200. By providing the bottom groove wall 311 of the cable guide 310 to extend downward from the inside to the outside, the power cable can extend downward along the cable guide 310 to the outside of the installation space. In this way, a clearance groove 21 can be opened on the cover 20 corresponding to the bottom end of the cable guide 310 as much as possible, thereby reducing the opening size of the clearance groove 21 on the cover 20, thus maintaining the continuity of the cover 20 and improving the overall structural strength of the cover 20.

[0082] Optionally, an indoor heat exchanger, an outdoor heat exchanger, and a compressor are installed inside the casing 20. The indoor heat exchanger, outdoor heat exchanger, and compressor are connected by refrigerant pipes to facilitate refrigerant circulation.

[0083] The chassis assembly 10 includes at least a compressor, an outdoor heat exchanger, and an electrical control box within its installation space. The power cable connecting the electrical control box extends from the cable tray 310.

[0084] The clearance groove 21 opens downwards, and the wire passage groove 311 opens upwards. The two cooperate with each other to confine the power line within the wire passage groove 311.

[0085] Optionally, a clamping claw can be provided on the outer surface of the housing 20 above the clearance groove 21. The power cord can be clamped in the clamping claw to prevent the power cord from moving back and forth outside the housing 20, so as to facilitate the upward routing of the power cord.

[0086] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
