Description

Technical Field

[0001] This application relates to the field of air conditioning technology, specifically to an electrical control box assembly and an air conditioner. Background Technology

[0002] In traditional air conditioners, the assembly of the control box cover and the box body is a crucial step. However, the existing control box design has a significant problem: the cover is easily installed backwards when it is attached to the box body.

[0003] Specifically, the lid and the side walls of the box body are usually designed symmetrically, which means that the lid can be installed onto the box body in two directions during installation.

[0004] Therefore, how to improve the structure of the electrical control box to prevent the cover from being installed backwards during installation is an urgent problem to be solved.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides an electrical control box assembly and an air conditioner to solve the problem that the box cover is easily installed backwards during installation.

[0008] According to a first aspect of the present invention, an electrical control box assembly is provided, comprising: an electrical control box including a box body and a box cover disposed at the opening of the box body, the box body including a first box side wall and a second box side wall disposed opposite to the first box side wall, the box cover having a first cover side wall for cooperating with the first box side wall and a second cover side wall for cooperating with the second box side wall; and a terminal block box disposed outside the first box side wall; wherein the distance between the terminal block box and the opening of the box body is less than the height of the second cover side wall and greater than or equal to the height of the first cover side wall.

[0009] Optionally, the sidewall of the second cover may protrude partially toward the box body to form an interference edge, the height of which is greater than the distance between the terminal block box and the opening of the box body.

[0010] Optionally, the sidewall of the first cover abuts against the terminal block box.

[0011] Optionally, one of the side walls of the box body and the side wall of the lid is provided with a groove, and the other of the side walls of the box body and the side wall of the lid is provided with a protrusion. The protrusion is inserted into the groove to restrict the movement of the lid in the direction of separation from the box body.

[0012] Optionally, one of the side walls of the box body and the side wall of the lid is provided with a flange, and the side wall of the box body and the side wall of the lid together define a groove with the free end of the flange.

[0013] Optionally, one of the box body and the box lid is provided with a connecting part, and the other is provided with a connecting mating part. The connecting part and the connecting mating part are connected and are detachable.

[0014] Optionally, the box body includes a first sub-box body and a second sub-box body, which are joined together to form the box body. The first sub-box body and the second sub-box body are connected by TOX riveting technology.

[0015] Optionally, the electrical control box and / or terminal block box are provided with a wire outlet hole, and a sealing element is provided at the wire outlet hole, with a gap for the wire harness to pass through.

[0017] According to a second aspect of the present invention, an air conditioner is provided, comprising: an electronic control box assembly as described in any of the above embodiments.

[0018] The electrical control box assembly and air conditioner provided in this disclosure can achieve the following technical effects:

[0019] The height of the first cover sidewall is less than the height of the second cover sidewall to prevent interference between the first cover sidewall and the terminal block box. Specifically, when the first cover sidewall corresponds to the first box sidewall (i.e., the cover is correctly installed on the box), the first cover sidewall does not interfere with the terminal block box. However, when the second cover sidewall corresponds to the first box sidewall (i.e., the cover is installed backwards on the box), the second cover sidewall interferes with the terminal block box, preventing the cover from being installed backwards.

[0058] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0059] Combination Figure 1 and Figure 2 As shown, this disclosure provides a chassis 100 for an air conditioner.

[0060] An air conditioner consists of an indoor unit and an outdoor unit. The indoor unit includes a chassis 100, or the outdoor unit includes a chassis 100.

[0061] The following description uses the indoor unit, including the chassis 100, as an example to illustrate the chassis 100.

[0062] The chassis 100 defines the installation space, and the evaporator and fan of the indoor unit are located within the installation space.

[0063] The chassis 100 includes side plates 10 and a first reinforcing rib 107.

[0064] The side plate 10 is provided with an installation notch 103 for installing the air conditioner control box 60; the first reinforcing rib 107 is provided on the side plate 10 and surrounds the installation notch 103.

[0065] A first reinforcing rib 107 is provided on the side plate 10 to surround the mounting notch 103. The first reinforcing rib 107 can enhance the structural strength of the mounting notch 103, reduce the deformation of the mounting notch 103 during the stamping process of the chassis 100, and make the electrical control box 60 more stable during installation. This reduces problems such as the electrical control box 60 not being installed firmly or loose due to the deformation of the chassis 100 or the insufficient strength of the mounting notch 103, thereby improving the overall stability and reliability of the air conditioner.

[0066] like Figure 2 As shown, the first reinforcing rib 107 is arranged around the mounting notch 103. The first reinforcing rib 107 can be arranged to surround the entire mounting notch 103 (adapting to the shape of the mounting notch 103), or it can only surround a portion of the mounting notch 103. For example, if the mounting notch 103 is L-shaped, when the first reinforcing rib 107 surrounds the entire mounting notch 103, the first reinforcing rib 107 is an L-shape adapted to the mounting notch 103. When the first reinforcing rib 107 only surrounds a portion of the mounting notch 103, for example, if the first reinforcing rib 107 is in a straight line, it only corresponds to a portion of the L-shape.

[0067] Optionally, such as Figure 2 As shown, the sidewall of the mounting notch 103 includes a first sidewall 104 and a second sidewall 105. The first sidewall 104 and the second sidewall 105 are connected and the connection forms a first angle 106. The first reinforcing rib 107 includes a first rib segment 108 and a second rib segment 109. The first rib segment 108 is provided corresponding to the first sidewall 104, and the second rib segment 109 is provided corresponding to the second sidewall 105. The first rib segment 108 and the second rib segment 109 are connected and the connection forms a second angle 110 corresponding to the first angle 106.

[0068] The first rib segment 108 and the second rib segment 109 are respectively provided for the first sidewall 104 and the second sidewall 105 of the mounting notch 103, and form a second angle 110 at the connection point corresponding to the first angle 106. This structure allows the first reinforcing rib 107 to better fit the shape of the mounting notch 103, effectively reinforcing the two sidewalls of the mounting notch 103, further improving the load-bearing capacity and deformation resistance of the mounting notch 103, and ensuring the installation accuracy and stability of the air conditioning control box 60.

[0069] Optionally, such as Figure 2 As shown, the chassis 100 also includes a second reinforcing rib 111 and a third reinforcing rib 116.

[0070] The second reinforcing rib 111 is located in the middle of the side plate 10; the third reinforcing rib 116 is located between the first reinforcing rib 107 and the second reinforcing rib 111.

[0071] The second reinforcing rib 111 strengthens the middle part of the side plate 10 to prevent deformation of the middle part of the side plate 10. The third reinforcing rib 116 strengthens the area between the first reinforcing rib 107 and the second reinforcing rib 111, effectively dispersing the various forces subjected to the side plate 10 during use, improving the overall rigidity and deformation resistance of the side plate 10, thereby better supporting other components of the air conditioner and ensuring the normal operation of the air conditioner.

[0072] Reasonably arrange the positions and quantities of the reinforcing ribs (the first to third reinforcing ribs 116) so that the reinforcing ribs can fully exert their reinforcing effects, while avoiding problems such as material waste and complex structure caused by excessive or unreasonable distribution of the reinforcing ribs, and improving the design rationality and economy of the chassis 100.

[0073] Optionally, as Figure 2 shown, the second reinforcing rib 111 is in a closed figure.

[0074] The second reinforcing rib 111 being in a closed figure can form a relatively stable reinforcing structure. Compared with the reinforcing rib in a non-closed figure, it can disperse stress more evenly when bearing various loads, further improving the structural strength and stability of the middle part of the side plate 10 and enhancing the overall bearing capacity of the chassis 100.

[0075] The second reinforcing rib 111 in a closed figure can better form an organic whole with other reinforcing ribs and the side plate 10 itself, improving the coordination and consistency of the structure of the entire chassis 100 and helping to enhance the comprehensive performance of the chassis 100.

[0076] The second reinforcing rib 111 can be in a square shape, or an oval shape, or any other shape of a closed figure.

[0077] As Figure 2 shown, the second reinforcing rib 111 is in a square shape. The second reinforcing rib 111 includes the third to sixth rib segments 115. The third rib segment 112 and the sixth rib segment 115 are oppositely arranged and both extend along the length direction of the side plate 10. The fourth rib segment 113 is connected between one ends of the third rib segment 112 and the sixth rib segment 115. The fourth rib segment 113 is connected between one ends of the third rib segment 112 and the sixth rib segment 115. The fifth rib segment 114 is connected between the other ends of the third rib segment 112 and the sixth rib segment 115. The fourth rib segment 113 and the fifth rib segment 114 are oppositely arranged and both extend along the width direction of the side plate 10.

[0078] Optionally, as Figure 2 shown, the side plate 10 includes a third side wall 101. The third reinforcing rib 116 is oppositely arranged with the third side wall 101 and is provided between the second reinforcing rib 111 and the third side wall 101. The distance between the third reinforcing rib 116 and the middle part of the side plate 10 is greater than the distance between the third reinforcing rib 116 and the third side wall 101.

[0079] Setting the third reinforcing rib 116 between the second reinforcing rib 111 and the third side wall 101 and making the distance between it (the third reinforcing rib 116) and the middle part of the side plate 10 greater than the distance from the third side wall 101 can enable the third reinforcing rib 116 to play a better reinforcing role in the area of the third side wall 101, prevent the corners at the end of the side plate 10 from deforming, and further improve the anti-deformation ability of the side plate 10.

[0080] The third sidewall 101, the first reinforcing rib 107, the third reinforcing rib 116, and the second reinforcing rib 111 are arranged sequentially.

[0081] Optionally, such as Figure 2 As shown, the third reinforcing rib 116 extends along the width direction of the side plate 10.

[0082] The third reinforcing rib 116 extends along the width direction of the side plate 10 and is located close to the third side wall 101, so that the third reinforcing rib 116 can enhance the strength at both ends of the third side wall 101 of the side plate 10, and work with the second side wall 105 to enhance the strength of the middle part of the side plate 10, so that the ends and the middle part of the side plate 10 will not deform during the stamping process.

[0083] Optionally, such as Figure 2 As shown, the side plate 10 also includes a fourth side wall 102 disposed opposite to the third side wall 101, and the chassis 100 also includes a fourth reinforcing rib 117. The fourth reinforcing rib 117 is disposed between the second reinforcing rib 111 and the fourth side wall 102, and is disposed opposite to the second reinforcing rib 111. The distance between the fourth reinforcing rib 117 and the middle part of the side plate 10 is greater than the distance between the fourth reinforcing rib 117 and the fourth side wall 102.

[0084] The fourth reinforcing rib 117 is located on the side of the second reinforcing rib 111 away from the third reinforcing rib 116. The fourth reinforcing rib 117 is located between the second reinforcing rib 111 and the fourth side wall 102, and is arranged opposite to the second reinforcing rib 111. At the same time, the distance between the fourth reinforcing rib 117 and the middle of the side plate 10 is greater than the distance between the fourth reinforcing rib 117 and the fourth side wall 102. This design can effectively strengthen the area of ​​the side plate 10 close to the fourth side wall 102. The arrangement opposite to the third reinforcing rib 116 further improves the structural strength and stability of both sides of the side plate 10, ensuring that the side plate 10 can maintain good shape and performance when subjected to various loads.

[0085] The symmetrical arrangement of the fourth reinforcing rib 117 and the third reinforcing rib 116 makes the structure of the chassis 100 more symmetrical and balanced, which helps to improve the overall performance and quality of the chassis 100.

[0086] Optionally, the chassis 100 also includes a fifth reinforcing rib 118, which is located inside the second reinforcing rib 111.

[0087] The fifth reinforcing rib 118 is located inside the second reinforcing rib 111, which is equivalent to adding an additional supporting structure on the basis of the second reinforcing rib 111. This double reinforcing rib design (second reinforcing rib 111 and fifth reinforcing rib) can significantly improve the deformation resistance and load-bearing capacity of the chassis 100 in the middle of the side plate 10, and can effectively resist deformation caused by external forces or its own weight.

[0088] The fifth reinforcing rib extends along the length of the side plate 10 to prevent deformation in the middle of the side plate 10.

[0089] The number of fifth reinforcing ribs is one or more. When there are multiple fifth reinforcing ribs, they are arranged sequentially along the width direction of the side plate 10.

[0090] Optionally, such as Figure 1 As shown, the chassis 100 also includes a base plate 20 and a sixth reinforcing rib 201. The base plate 20 is connected to the side plate 10 and the connection forms a third angle. The sixth reinforcing rib 201 is provided on the base plate 20 and extends along the length of the base plate 20.

[0091] The sixth reinforcing rib 201 extending along the length of the base plate 20 is provided on the base plate 20, which can enhance the longitudinal rigidity and deformation resistance of the base plate 20. It plays an important role in resisting the longitudinal load that the base plate 20 may be subjected to during use, further improving the overall structural stability of the chassis 100, and ensuring that the base plate 20 will not be excessively deformed or damaged during the stamping process.

[0092] The bottom plate 20 is connected to the side plate 10 and forms a third angle. This structural design makes the overall structure of the chassis 100 more complete and compact. At the same time, the setting of the sixth reinforcing rib 201 can better coordinate with other reinforcing ribs and structures such as the side plate 10 and the bottom plate 20, thereby improving the overall performance and reliability of the chassis 100.

[0093] Optionally, such as Figure 1 As shown, the chassis 100 also includes a seventh reinforcing rib 202, which is located at the end of the sixth reinforcing rib 201 and extends along the width direction of the base plate 20.

[0094] A seventh reinforcing rib 202 extending along the width direction of the base plate 20 is provided at the end of the sixth reinforcing rib 201, which can strengthen the end area of ​​the base plate 20, improve the rigidity and deformation resistance of the base plate 20 in the width direction, prevent deformation at the four corners of the base plate 20, further enhance the overall structural strength of the base plate 20, and ensure that the base plate 20 can maintain good shape and performance when subjected to various loads.

[0095] By rationally arranging the sixth reinforcing rib 201 and the seventh reinforcing rib 202 on the base plate 20, the various forces subjected to the base plate 20 during use can be effectively dispersed, the load-bearing capacity of the base plate 20 can be improved, thereby better supporting other components of the air conditioner and ensuring the normal operation and service life of the air conditioner.

[0096] There are multiple sixth reinforcing ribs 201, which are arranged sequentially along the width direction of the base plate 20. One or more sixth reinforcing ribs 201 are provided with a seventh reinforcing rib 202 at their ends. The seventh reinforcing rib 202 and the sixth reinforcing ribs 201 where the seventh reinforcing rib 202 is located together form an I-shape or a similar I-shape.

[0097] A second aspect of this utility model provides an air conditioner, including a chassis 100 for an air conditioner as described in any of the above embodiments.

[0098] The air conditioner provided in the second aspect of this utility model includes the chassis 100 for air conditioning as described in any of the above embodiments, and therefore has all the beneficial effects of the chassis 100 as described in any of the above embodiments, which will not be repeated here.

[0099] A third aspect of this utility model provides an indoor unit, wherein the air conditioner includes an indoor unit and an outdoor unit connected to the indoor unit.

[0100] like Figures 3 to 9 As shown, the indoor unit includes a housing 300, electrical components, an indoor heat exchanger 50, and a fresh air duct 40.

[0101] The housing 300 includes a chassis 100 and a panel 303. There are two side panels 10, which are arranged opposite each other. The two side panels 10 and the bottom plate 20 together enclose a U-shaped space. The panel 303 covers the opening end of the U-shape and is connected between the two side panels 10.

[0102] like Figure 7 As shown, the housing 300 defines an installation area 503 and an air duct 504, meaning the U-shaped space includes the installation area 503 and the air duct 504. The installation area 503 and the air duct 504 are arranged sequentially along the length of the indoor unit.

[0103] like Figure 4 As shown, the housing 300 also includes a first assembly plate 301 and a second assembly plate 302, which are disposed opposite to each other. The first assembly plate 301 is connected between one end of the base plate 20 and the panel 303, and the other end of the base plate 20 is connected between the first assembly plate 301 and the panel 303. The mounting area 503 and the air duct 504 are arranged sequentially from the first assembly plate 301 to the second assembly plate 302.

[0104] The housing 300 also includes a fresh air inlet 304, for example, the fresh air inlet 304 is located on the first assembly plate 301. The first assembly plate 301 has a perforated structure. Specifically, the first assembly plate 301 has a detachable plate 305, which is located at the fresh air inlet 304. There are multiple connections between the perimeter of the detachable plate 305 and the inner wall of the fresh air inlet 304. These connections are perforated to facilitate the removal of the connections, thereby removing the detachable plate 305 to allow for the installation of the fresh air duct 40 at the fresh air inlet 304. The panel 303 has an air inlet 501 and an air outlet 502, both of which are connected to the air duct 504. Electrical components are installed in the installation area 503; indoor heat exchanger 50 is installed in the air duct 504; fresh air duct 40 is installed in the installation area 503, with the first end 405 of the fresh air duct 40 connected to the fresh air inlet 304 and the second end 406 of the fresh air duct 40 connected to the air duct 504.

[0105] like Figure 7 As shown, by setting a fresh air duct 40 inside the housing 300, and connecting the first end 405 of the fresh air duct 40 to the fresh air inlet 304 and the second end 406 to the air duct 504, outdoor air enters the fresh air duct 40 through the fresh air inlet 304 and flows to the air duct 504, so that the air conditioner has a fresh air function and can introduce fresh outdoor air.

[0106] The design of the fresh air duct 40 provides a clear and fixed channel for fresh air, preventing fresh air from wandering around after entering the indoor unit, reducing the loss of fresh air volume, and improving the utilization efficiency of fresh air.

[0107] Electrical components are located within the installation area 503, and the fresh air duct 40 is also located within the installation area 503. Since the fresh air flows in the fresh air duct 40 rather than directly within the installation area 503, the fresh air will not directly contact the electrical components. Moreover, the arrangement of the fresh air duct 40 allows the fresh air to flow through the duct 40 in an orderly and efficient manner to the air duct 504, preventing the fresh air from wandering around within the installation area 503. This reduces the residence time of the fresh air within the installation area 503 and reduces the phenomenon of condensation on the surface of electrical components caused by the introduction of cold air (when the outdoor air is cold), thereby reducing the possibility of condensation posing a risk to the electrical components.

[0108] Optionally, such as Figure 7 As shown, the indoor unit also includes fan blades, which are located in the air duct 504; electrical components include a motor 509, which is connected to the fan blades and is located in the installation area 503, and a fresh air duct 40 is located on the side of the motor 509.

[0109] The motor 509 drives the fan blades to rotate, which on the one hand drives indoor air to enter the air duct 504 through the air inlet 501, exchange heat with the indoor heat exchanger 50 and then flow out from the air outlet 502. On the other hand, it drives outdoor air to enter the fresh air duct 40 through the fresh air inlet 304 and flow into the air duct 504, so that there is no need to install a fresh air fan to drive the flow of fresh air.

[0110] The motor 509 is located in the installation area 503, and the fresh air duct 40 is located on the side of the motor 509. The fresh air flows in the fresh air duct 40 and will not come into direct contact with the motor 509. This avoids the waste heat of the motor 509 coming into direct contact with the fresh air, which would cause condensation to form on the surface of the motor 509, thus protecting the motor 509.

[0111] Optionally, there is a gap between the fresh air duct 40 and the motor 509, that is, the two do not come into direct contact, further preventing condensation from forming on the surface of the motor 509 due to the introduction of fresh air.

[0112] Optionally, such as Figure 6 As shown, the surface of the fresh air duct 40 facing the motor 509 is provided with a first clearance groove 403 for avoiding the motor 509.

[0113] The surface of the fresh air duct 40 facing the motor 509 is provided with a first clearance groove 403, which can effectively avoid interference between the fresh air duct 40 and the motor 509 and ensure the normal operation of the motor 509.

[0114] The fresh air duct 40 includes a first pipe section 401 and a second pipe section 402 arranged sequentially along its length; the connection between the first pipe section 401 and the second pipe section 402 forms a first bend on the surface facing the motor 509, and the motor 509 is located at the first bend, that is, the first bend forms a first clearance groove 403.

[0115] Optionally, such as Figure 7 As shown, the indoor unit also includes an electrical control box 60, which is located in the housing 300 and is installed in the corresponding installation area 503. The fresh air duct 40 is located between the electrical control box 60 and the housing 300.

[0116] The electrical control box 60 houses a computer board 90, and electrical components are included within the computer board 90. The electrical control box 60 is located within the housing 300 and corresponds to the installation area 503. The fresh air duct 40 is located between the electrical control box 60 and the housing 300. This layout separates the electrical components from the fresh air duct 40. Fresh air flows within the fresh air duct 40 and does not directly contact the electrical control box 60, further reducing the possibility of condensation on the surface of the electrical control box 60 during fresh air introduction posing a risk to the electrical components, thus improving the safety and reliability of the air conditioner.

[0117] Optionally, such as Figure 5As shown, the surface of the fresh air duct 40 facing the electrical control box 60 is provided with a second clearance groove 404 for avoiding the electrical control box 60.

[0118] The surface of the fresh air duct 40 facing the electrical control box 60 is provided with a second clearance groove 404, which can effectively avoid interference between the fresh air duct 40 and the electrical control box 60, and ensure the normal installation and use of the electrical control box 60.

[0119] The connection between the first pipe section 401 and the second pipe section 402 forms a second bend on the surface of the electrical control box 60. The electrical control box 60 is located at the second bend, that is, the second bend forms a second clearance groove 404.

[0120] Optionally, such as Figure 7 As shown, the housing 300 is provided with an air inlet 501 and an air outlet 502, both of which are connected to the air duct 504; the second end 406 of the fresh air duct 40 is located between the indoor heat exchanger 50 and the air inlet 501.

[0121] The second end 406 of the fresh air duct 40 is located between the indoor heat exchanger 50 and the air inlet 501, so that fresh air can be directly introduced to the air inlet 501 side of the evaporator, mixed with the indoor air, and then exchanged heat through the evaporator, thereby improving the heat exchange efficiency.

[0122] Optionally, the indoor heat exchanger 50 includes a first end 5011 and a second end 5012 arranged sequentially along the direction from the installation area 503 to the air duct 504, and the second end 406 of the fresh air duct 40 is located between the first end 5011 of the indoor heat exchanger 50 and the air inlet 501.

[0123] The two ends of the indoor heat exchanger 50 along its length are a first end 5011 and a second end 5012, wherein the first end 5011 is located closer to the installation area 503 than the second end 5012.

[0124] The second end 406 of the fresh air duct 40 is located between the first end 5011 of the indoor heat exchanger 50 and the air inlet 501, which reduces the length of the fresh air duct 40, lowers the cost, and avoids excessive air resistance caused by an excessively long fresh air duct 40, which would affect the flow of air from the air inlet 501 toward the indoor heat exchanger 50.

[0125] Optionally, such as Figure 6 As shown, the flow area of ​​the second end 406 of the fresh air duct 40 is smaller than that of the first end 405.

[0126] The flow area of ​​the second end 406 of the fresh air duct 40 is smaller than that of the first end 405. This design can effectively control the flow rate and volume of the fresh air, so that the fresh air can be better mixed with the indoor air after entering the air duct 504. This avoids the problem of uneven heat exchange caused by excessive fresh air, improves the heat exchange efficiency and comfort of the air conditioner, and makes the size of the second end 406 of the fresh air duct 40 smaller than the size of the first end 405 of the fresh air duct 40. This avoids the problem of excessive wind resistance between the indoor heat exchanger 50 and the air inlet 501 due to the size of the second end 406, which would affect the air intake of the indoor heat exchanger 50.

[0127] Optionally, such as Figure 3 As shown, the fresh air duct 40 includes a duct body 407 and an insulation component 408. The insulation component 408 is located on the outside of the duct body 407.

[0128] Fresh air flows inside the duct body 407, and the insulation component 408 is wrapped around the outside of the duct body 407 to reduce the heat exchange between the fresh air inside the duct body 407 and the outside.

[0129] The main body of the pipeline 407 can be a one-piece structure or a split structure, for example, it includes a first main body 409 and a second main body 410, such as... Figure 8 and Figure 9 As shown, the first body 409 and the second body 410 are arranged sequentially along the width direction of the pipe body 407, and the two are joined together to form the pipe body 407. The first body 409 and the second body 410 can be detachable connected by snap-fit, screw connection or other detachable connection methods, or they can be non-detachable connected methods.

[0130] The insulation component 408 is located on the outside of the duct body 407, which can effectively reduce the heat loss of fresh air in the duct, maintain the temperature of fresh air relatively stable, improve heat exchange efficiency, and at the same time isolate the cold fresh air and electrical components inside the duct body 407, further preventing condensation from forming on the surface of electrical components.

[0131] A fourth aspect of this utility model provides an air conditioner, including an indoor unit as described in any one of the third aspect embodiments.

[0132] The air conditioner provided in the fourth aspect of this utility model includes an indoor unit as described in any one of the embodiments of the third aspect, and therefore has all the beneficial effects of an indoor unit as described in any one of the embodiments of the third aspect, which will not be repeated here.

[0133] A fifth aspect of this utility model provides an electrical control box assembly, including an electrical control box 60 and a terminal block box 510.

[0134] like Figures 10 to 15As shown, the electrical control box 60 includes a box body 601 and a box cover 630 covering the opening of the box body 601. The box body 601 includes a first box side wall 602 and a second box side wall 603 disposed opposite to the first box side wall 602. The box cover 630 is provided with a first cover side wall 631 for cooperating with the first box side wall 602 and a second cover side wall 632 for cooperating with the second box side wall 603.

[0135] Terminal block box 510 is located on the outside of the side wall 602 of the first box.

[0136] The distance between the terminal block box 510 and the opening of the box body 601 is less than the height of the second cover side wall 632 and greater than or equal to the height of the first cover side wall 631.

[0137] Thus, the height L1 of the first cover sidewall 631 is less than the height L2 of the second cover sidewall 632 to prevent interference between the first cover sidewall 631 and the terminal block box 510. Specifically, as follows... Figure 11 and Figure 12 As shown, when the first cover sidewall 631 corresponds to the first box sidewall 602, that is, when the cover 630 is correctly installed on the box body 601, the first cover sidewall 631 does not interfere with the terminal block box 510. When the second cover sidewall 632 corresponds to the first box sidewall 602, that is, when the cover 630 is installed backwards on the box body 601, the second cover sidewall 632 interferes with the terminal block box 510, making it impossible for the cover 630 to be installed on the box body 601, thereby achieving the anti-reverse installation of the cover 630.

[0138] Optionally, such as Figure 11 As shown, the second cover sidewall 632 partially protrudes towards the box body 601 to form an interference edge 635, and the height of the interference edge 635 is greater than the distance between the terminal block box 510 and the opening of the box body 601.

[0139] Along the length of the first box sidewall 602, the size of the terminal block box 510 is smaller than that of the electrical control box 60. Therefore, a portion of the first box sidewall 602 corresponds to the terminal block box 510, meaning the terminal block box 510 only covers the corresponding portion of the first box sidewall 602. The interference edge 635 is positioned opposite to this corresponding portion. This way, if the box cover 630 is installed backwards, the interference edge 635 will interfere with the terminal block box 510, preventing the box cover 630 from being installed backwards. If the interference edge 635 is offset from the corresponding portion, even if the box cover 630 is installed backwards, the interference edge 635 may be offset from the terminal block box 510, causing the terminal block box 510 to not contact the interference edge 635, thus failing to achieve the effect of installing the box cover 630 backwards.

[0140] The second cover sidewall 632 partially protrudes towards the box body 601 to form an interference edge 635, and the height of the interference edge 635 is greater than the distance between the terminal block box 510 and the opening of the box body 601. This design ensures that when the cover 630 is installed backwards, the interference edge 635 will interfere with the terminal block box 510, thus preventing incorrect installation of the cover 630 and further enhancing the anti-reverse installation function, ensuring that the cover 630 can only be installed in the correct orientation.

[0141] The second cover sidewall 632 has a partial protrusion forming an interference edge 635. While preventing the cover 630 from being installed backwards, it can reduce the area of ​​the interference edge 635, reduce the material used in the cover 630, and lower the cost of the cover 630.

[0142] Optionally, the cover 630 is correctly installed on the box body 601, and when installed in place, the first cover sidewall 631 abuts against the terminal block box 510.

[0143] The contact relationship between the first cover sidewall 631 and the terminal block box 510 can form a good sealing fit when the cover 630 is correctly installed, which further improves the sealing performance of the electrical control box 60, prevents external impurities from entering, and protects the normal operation of internal components.

[0144] Optionally, such as Figures 13 to 15 As shown, one of the side walls of the box body 601 and the side wall of the lid 630 is provided with a groove 607, and the other of the side walls of the box body 601 and the lid 630 is provided with a protrusion 636. The protrusion 636 is inserted into the groove 607 to restrict the lid 630 from moving in the direction of separation from the box body 601.

[0145] The side walls of the box body 601 include a first box side wall 602, a second box side wall 603, a third box side wall 604, and a fourth box side wall 605; the side walls of the lid 630 include a first lid side wall 631, a second lid side wall 632, a third lid side wall 633, and a fourth lid side wall 634. The third box side wall 604 is connected between one end of the first box side wall 602 and one end of the second box side wall 603, and the fourth box side wall 605 is connected between the other end of the first box side wall 602 and the other end of the second box side wall 603, and is disposed opposite to the third box side wall 604. The third lid side wall 633 corresponds to the third box side wall 604, and the fourth lid side wall 634 corresponds to the fourth box side wall 605.

[0146] One of the side walls of the box body 601 and the side wall of the box cover 630 is provided with a groove 607, and the other is provided with a protrusion 636. The protrusion 636 is inserted into the groove 607. The cooperation between the protrusion 636 and the groove 607 not only restricts the movement of the box cover 630 in the direction of separation from the box body 601, but also effectively prevents the box cover 630 from accidentally falling off due to vibration or other external forces during use, thereby improving the structural stability and reliability of the electrical control box 60.

[0147] Optionally, such as Figure 15 As shown, one of the side walls of the box body 601 and the box cover 630 is provided with a flange 606, and the side wall of the box body 601 and the side wall of the box cover 630 together with the free end of the flange 606 define a groove 607.

[0148] The side wall of the box body 601 is bent outward at the opening to form a flange 606. The free end of the flange 606 and the side wall of the box body 601 together form a groove 607. The side wall of the box lid 630 has a protrusion 636, which is inserted into the groove 607. Alternatively, the side wall of the box lid 630 is bent outward or inward to form a flange 606. The free end of the flange 606 and the side wall of the box lid 630 together form a groove 607. The side wall of the box body 601 has a protrusion 636, which is inserted into the groove 607.

[0149] By setting the flange 606 to form the groove 607, the strength of the side wall of the box body 601 or the box cover 630 where the flange 606 is located can also be enhanced.

[0150] The number of protrusions 636 can be one or more, such as Figure 15 As shown, the third box side wall 604 is provided with a flange 606, and the third cover side wall 633 is provided with a protrusion 636. There are multiple protrusions 636, and the multiple protrusions 636 are arranged sequentially along the length direction of the third cover side wall 633.

[0151] Optionally, one of the box body 601 and the box cover 630 is provided with a connecting part, and the other is provided with a connecting mating part. The connecting part and the connecting mating part are connected and are detachably connected.

[0152] The detachable connection method allows for easy disassembly and installation between the cover 630 and the body 601, facilitating the maintenance, repair, and replacement of components inside the electrical control box 60, and greatly improving the maintainability and repairability of the product.

[0153] The lid has a connecting part, which is a first screw hole 637 and a connecting mating part is a second screw hole. The screw passes through the first screw hole and the second screw hole to realize the screw connection between the connecting part and the connecting mating part; or, the connecting part and the connecting mating part can also be a snap-fit ​​or other detachable connection method.

[0154] Optionally, the air conditioner is a recessed air conditioner. When the air conditioner is installed, the cover 630 is located below the box body 601. When it is necessary to repair the components inside the control box 60, first disengage the connection part and the connecting mating part. At this time, due to the fit between the protrusion 636 and the groove 607, the cover 630 will not fall off, eliminating the need to hold the cover 630 by hand, thus improving the convenience of disassembling the cover 630. The protrusion 636 and the groove 607 are interference-fitted, so when the cover 630 is assembled onto the box body 601, the protrusion 636 will snap into the groove 607, producing a tactile feedback and a clicking sound, indicating to the operator that the cover 630 is properly assembled.

[0155] Optionally, the box body 601 includes a first sub-box body 601 and a second sub-box body 601, which are joined together to form the box body 601. The first sub-box body 601 and the second sub-box body 601 are connected by TOX riveting technology.

[0156] Compared to traditional welding or riveting methods, TOX riveting technology offers higher connection precision and strength, effectively preventing deformation and loosening at the joints of box 601, improving the structural stability and reliability of the entire box 601, and also enhancing the aesthetics of box 601.

[0157] Optionally, the electrical control box 60 and / or terminal block box 510 are provided with a wire outlet hole, and a sealing element 511 is provided at the wire outlet hole. The sealing element 511 is provided with a gap 512 for the wire harness to pass through.

[0158] This feature ensures that the wiring harness (high-voltage wires and / or low-voltage wires) can pass through smoothly, while sealing the outlet hole with the sealing element 511, effectively preventing external dust, moisture and other impurities from entering the electrical control box 60, and further improving the sealing performance of the product.

[0159] The seals can be made of rubber, providing a good seal and an aesthetically pleasing appearance.

[0160] Optionally, the electrical control box 60 and the terminal block box 510 are connected using TOX riveting technology.

[0161] The electrical control box 60 and the terminal block box 510 are connected by TOX riveting technology. This advanced riveting technology can achieve a more secure and tighter connection between the two. Compared with the traditional connection method, it has higher connection strength and stability, effectively preventing the terminal block box 510 from loosening or falling off due to external force during use, and also improving the aesthetics.

[0162] A sixth aspect of the present invention provides an air conditioner, including an electrical control box assembly as described in any one of the fifth aspects of the embodiments.

[0163] The air conditioner provided in the sixth aspect of this utility model includes the electronic control box assembly as described in any one of the embodiments of the fifth aspect, and therefore has all the beneficial effects of the electronic control box assembly as described in any one of the embodiments of the fifth aspect, which will not be repeated here.

[0164] like Figures 16 to 18 As shown, an embodiment of the seventh aspect of this utility model provides a wiring structure for an air conditioner, including a computer board 90, a mounting plate 70, and a terminal block 80.

[0165] The air conditioner also includes an electrical control box 60 and a terminal block box 510. The computer board 90 is located inside the electrical control box 60; the terminal block box 510 is located outside the electrical control box 60, and the mounting plate 70 is located inside the terminal block box 510.

[0166] like Figure 16 and Figure 17 As shown, the mounting plate 70 includes a first plate surface 709 and a second plate surface 710 disposed opposite to the first plate surface 709; a terminal block 80 is disposed on the first plate surface 709; one of the first high-voltage wire 901 and the first low-voltage wire led out from the computer board 90 is connected to the terminal block 80 via the first plate surface 709, and the other of the first high-voltage wire 901 and the first low-voltage wire is connected to the terminal block 80 via the second plate surface 710.

[0167] The first high-voltage wire 901 is connected to the terminal block 80 via the first board surface 709, and the first low-voltage wire is connected to the terminal block 80 via the second board surface 710. Alternatively, the first high-voltage wire 901 is connected to the terminal block 80 via the second board surface 710, and the first low-voltage wire is connected to the terminal block 80 via the first board surface 709, thus realizing the layered routing of the first high-voltage wire 901 and the first low-voltage wire.

[0168] By connecting the first strong wire 901 and the first weak wire to the terminal block 80 through different boards (first board 709 and second board 710), the strong and weak wires are effectively separated, avoiding direct contact and electromagnetic interference between the strong and weak wire bundles.

[0169] By utilizing the first panel 709 and the second panel 710 to route the first high-voltage wire 901 and the first low-voltage wire in layers, the vertical space of the mounting plate 70 is fully utilized. Compared with the traditional planar layout, this reduces the area occupied by the wire harness in a single plane and optimizes space utilization efficiency. Moreover, this layered routing method simplifies the wiring structure, making the wire harness layout clearer and more orderly, which is convenient for production assembly and after-sales maintenance.

[0170] Optionally, such as Figure 16 As shown, the plane containing the first plate surface 709 and the second plate surface 710 is parallel to or coincides with the computer board 90.

[0171] The first board surface 709 and the second board surface 710 are parallel to or overlap with the computer board 90, making the entire wiring structure more compact and further optimizing space utilization.

[0172] The parallel layout makes the connection between the mounting plate 70 and the computer board 90 more stable and reduces structural deformation caused by wire harness pulling.

[0173] Optionally, such as Figure 17 As shown, the first high-voltage wire 901 is connected to the terminal block 80 after passing through the second plate 710. The wiring structure also includes a magnetic ring 711, which is located on the second plate 710.

[0174] The first high-voltage wire 901 is connected to the terminal block 80 after passing through the second plate 710. The magnetic ring 711 is set on the second plate 710 to facilitate the use of the magnetic ring 711 and the high-voltage wire.

[0175] Optionally, such as Figure 18 As shown, the first panel 709 includes a first region 701 and a second region 702, and a terminal block 80 is disposed between the first region 701 and the second region 702; the terminal block 80 has its connection port for connecting the wires from the outdoor unit facing the first region 701, and the connection port for connecting the first strong wire 901 and the first weak wire facing the second region 702.

[0176] The first panel 709 is divided into a first area 701 and a second area 702 by the terminal block 80. The terminal block 80's connection port facing the first area 701 connects to the wires from the outdoor unit, and the terminal block 80's connection port facing the second area 702 connects to the first high-voltage wire 901 and the first low-voltage wire. In other words, the terminal block 80's connection port includes a first connection port 801 and a second connection port 802. The first connection port 801 connects to the wires from the outdoor unit, and the second connection port 802 connects to the first high-voltage wire 901 and the first low-voltage wire. This achieves zoned management of different functional wire harnesses, making the wire harness access more orderly, reducing the crossing between different functional wire harnesses, further reducing the risk of electromagnetic interference, and further optimizing the wire harness layout.

[0177] Optionally, such as Figure 18 As shown, the wiring structure also includes a first separating rib 703, which is located in the first area 701 and is used to separate the high-voltage wires and low-voltage wires that run through the first area 701.

[0178] The first separating rib 703 is set in the first area 701, which effectively separates the strong wires and weak wires that run through the first area 701, further enhancing the isolation effect between strong and weak wires, reducing electromagnetic interference from strong wires to weak wires, and improving the stability of signal transmission of weak wires.

[0179] For example, the second high-voltage wire 906 and the second low-voltage wire 907 from the outdoor unit both pass through the first area 701 and are connected to the first terminal 801. The first low-voltage wire includes the first sub-low-voltage wire 903, which also passes through the first area 701 and is connected to the outdoor unit. The first sub-low-voltage wire 903 and the second low-voltage wire 907 are located on one side of the first partition rib 703, and the second high-voltage wire 906 is located on the other side of the first partition rib 703.

[0180] The extension direction of the first dividing rib 703 is approximately consistent with the extension direction of at least one of the first weak wire 903, the second weak wire 907, and the second strong wire 906.

[0181] Optionally, the wiring structure further includes a first limiting rib 704, which is disposed in the first region 701 and defines a first wiring space 705 for the wire harness to pass through.

[0182] The first limiting rib 704 defines the first wiring space 705, which limits the first sub-low voltage wire 903 and provides a fixed wiring path for the first sub-low voltage wire 903, avoiding messiness and tangling of the wire harness. Moreover, by defining the first wiring space 705, the space utilization of the wire harness in the first area 701 is further optimized, making the internal layout of the entire electrical control box 60 more compact.

[0183] Optionally, the wiring structure also includes a second partition 706, which is located in the second region 702 and is used for the first high-voltage wire 901 and the first low-voltage wire of the wiring passing through the second region 702.

[0184] The second partition rib 706 is disposed in the second area 702. The wires of the first strong wire 901 and the first weak wire that run through the second area 702 are separated by the second partition rib 706. For example, the first weak wire includes a second sub-weak wire 904. The second sub-weak wire 904 runs through the second area 702. The second partition rib 706 separates the first strong wire 901 and the second sub-weak wire 904. The second sub-weak wire 904 is connected to the second terminal 802 of the terminal block 80, which enhances the isolation effect between strong and weak wires, further reduces the electromagnetic interference of the strong wire to the weak wire, and improves the stability of the signal transmission of the weak wire.

[0185] Optionally, such as Figure 18 As shown, the wiring structure also includes a second limiting rib 707, which is located in the second region 702 and defines a second wiring space 708 for the wire harness to pass through.

[0186] The second limiting rib 707 defines the second wiring space 708. The first low-voltage wire also includes a third sub-low-voltage wire 905. The third sub-low-voltage wire 905 is not connected to the terminal block 80, but is routed through the second wiring space 708, thereby providing a fixed wiring path for the third sub-low-voltage wire 905 and avoiding messiness and tangling of the wire harness.

[0187] The second separator 706 can also be used to separate the first strong wire 901 and the third weak wire 905.

[0188] The first limiting rib 704 and the second limiting rib 707 are both located on the side of the mounting plate 70 facing the computer board 90 to facilitate wiring and prevent the wire harness from being too long when passing through the first wiring space 705 and the second wiring space 708.
