Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and in particular to an electric control box installation structure and an air conditioner. Background Art

[0002] As people's living standards improve, the use of air conditioners is becoming more and more common. The electric control box, as the "brain" of the air conditioner, contains a variety of electric control components and circuits. Therefore, it is very easy to have problems and needs to be opened frequently for maintenance. However, for existing air conditioners, the electric control box is generally fixedly installed in the middle frame. When repairing the electric control box, it is usually necessary to first remove the panel and the middle frame, and then take out and open the electric control box for maintenance. The maintenance process is very cumbersome and difficult.

[0003] In order to solve the problem of difficulty in repairing the electric control box, the prior art discloses an air conditioner with a pull-out electric control box. When repairing the electric control box with this structure, the electric control box can be taken out by removing the cover plate and pulling the electric control box outward. Although the electric control box with this structure reduces the difficulty of repairing the electric control box to a certain extent, it still has the following defects:

[0004] First, after the electric control box is pulled out, the maintenance personnel still need to stand at a high place and hold the electric control box to perform maintenance, or completely remove the electric control box and place it on a convenient maintenance operating table for maintenance, which makes the maintenance of the electric control box still very inconvenient;

[0005] Second, the installation structure of the pull-out electric control box is complex, and the changes to the internal structure of the air conditioner are large and difficult to implement. Summary of the invention

[0006] The present invention designs an electric control box installation structure and an air conditioner, so as to realize the purpose that the electric control box can be opened simply and quickly, and the installation structure of the electric control box is simple and easy to realize.

[0007] In order to solve the above problems, the present invention discloses an electric control box installation structure, including an electric control box and a middle frame, an end cover is arranged at the end of the middle frame, a partial area of ​​the end cover is hollowed out to form an installation port of the electric control box, one side of the electric control box is rotatably installed on the installation port, and the other side is detachably connected to the middle frame through a fixed connection structure.

[0008] The electric control box installation structure described in the present application makes the installation structure of the electric control box simple, easy to open and close, and simple to maintain by setting the electric control box to be rotated to open. In addition, the setting of the fixed connection structure makes the installation of the electric control box stable, and it will not be opened at will during the use of the air conditioner without human operation.

[0009] Furthermore, a rotating shaft and the fixed connection structure are respectively provided on two opposite sides of the electric control box, one side of the electric control box is rotatably mounted on the mounting opening via the rotating shaft, and the opposite side is detachably connected to the middle frame via the fixed connection structure.

[0010] The rotating shaft and the fixed connection structure are respectively arranged on two opposite sides of the electric control box, so that the installation of the electric control box can be more stable and the force is evenly distributed.

[0011] Furthermore, when the air conditioner is in use, the electric control box is in a closed state, the rotating shaft is horizontally arranged on the middle frame, the fixed connection structure is located on the upper side of the electric control box, and the rotating shaft is located on the lower side of the electric control box.

[0012] The fixed connection structure is arranged on the upper side of the electric control box, and the rotating shaft is arranged on the lower side of the electric control box, so that after the fixed connection structure on the upper side of the electric control box is opened, the electric control box can be rotated downward to open, and the operation is convenient. The maintenance personnel can easily observe the situation inside the electric control box, which is convenient for the later maintenance of the electric control box.

[0013] Furthermore, when the electric control box is in an open state, the electric control box can be horizontally fixed on one end of the middle frame.

[0014] The state of the electric control box when in the open state is set to be horizontally fixed at the end of the middle frame, so that during the later maintenance process of the electric control box, there is no need to apply additional supporting force to the electric control box, and the components inside the electric control box will not roll randomly, which makes it easy for maintenance personnel to observe the inside of the electric control box and perform maintenance.

[0015] Furthermore, the electric control box includes a box body and a cover plate, wherein the cover plate is located on one side of the box body. When the electric control box is in a closed state, the box body is located in the middle frame, and the cover plate covers the mounting opening. The cover plate and the end cover together constitute the end surface of the middle frame.

[0016] The arrangement of the cover plate can ensure that the electric control box has good sealing performance, is not easily damaged, and is not easily entered by insects and mice, etc.; and the installation structure of the electric control box has a high aesthetic level.

[0017] Furthermore, the shape of the cover plate is set to correspond to the shape of the end cover before being hollowed out, so that after the cover plate is covered on the installation opening, the end surface of the middle frame has the same shape as before being hollowed out.

[0018] The structural optimization of the cover plate ensures that when the electric control box is in a closed state, the end surface of the middle frame is consistent with the appearance of the end cover before being hollowed out, further improving the aesthetics of the electric control box installation structure.

[0019] Furthermore, the fixed connection structure is respectively arranged on the electric control box, the end cover and the base, and the electric control box is respectively connected to the end cover and the base through the fixed connection structure.

[0020] The electric control box, the end cover and the base can be mutually connected, supported and fixed through the fixed connection structure, so that the electric control box, the end cover and the base can form a whole with strong connection stability.

[0021] Furthermore, the fixed connection structure includes a first fixed connection hole arranged on the base, a second fixed connection hole arranged on the end cover, and a third fixed connection hole and a fourth fixed connection hole arranged on the cover plate. When the electric control box is in a closed state, the first fixed connection hole can overlap and connect with the third fixed connection hole; the second fixed connection hole can overlap and connect with the fourth fixed connection hole.

[0022] By providing the first fixed connection hole, the second fixed connection hole, the third fixed connection hole and the fourth fixed connection hole, fixed connection between the base, the end cover and the cover plate is achieved.

[0023] Furthermore, a partial area of ​​the end cover is recessed into the interior of the middle frame to form a sunken platform, and the first fixed connection hole is formed on the sunken platform. When the cover plate is closed on the installation opening, part of the cover plate can be accommodated in the sunken platform.

[0024] Through the cooperation of the sink and the cover, the cover and the end cover are installed together in a staggered and overlapping manner through the sink, further improving the sealing of the electric control box, the aesthetics of the electric control box installation structure and the connection stability between the cover and the end cover.

[0025] Furthermore, one end of the rotating shaft is connected to the middle frame, and the other end is connected to the base.

[0026] The electric control box, the end cover and the base can be further connected, supported and fixed to each other through the rotating shaft, so that the electric control box, the end cover and the base can form a whole with stronger connection stability.

[0027] Furthermore, a limit platform is provided on the base, and the limit platform is a protrusion arranged at the end of the base. When the electric control box is rotated and opened to a horizontal position, the cover plate can be tightly attached to the limit platform, so that the electric control box cannot continue to rotate.

[0028] The setting of the limiting platform enables the electric control box to be fixed in a horizontal position after being opened, so that the electric control box can be easily repaired.

[0029] Furthermore, the installation structure of the electric control box also includes a winding structure, which includes a winding shaft and an electric wire wound on the winding shaft. By rotating the winding shaft, the length of the electric wire can be increased or shortened.

[0030] The winding structure enables the timely retraction and release of the wires, thereby preventing the wires from being broken due to pulling when the electric control box is opened or the excess wires from being unable to be retracted in time and being tangled in a disorderly manner inside the electric control box when the electric control box is closed.

[0031] Furthermore, the winding structure also includes a support, which is formed on the inner side of the end cover. A bayonet is provided on the support, and both ends of the winding shaft can be rotatably inserted into the bayonet.

[0032] By setting the support, the winding shaft can be rotatably fixed on the inner side of the end cover, so that the length of the electric wire can be adjusted by rotation.

[0033] Furthermore, a spring is sleeved on the winding shaft, one end of the spring is fixed on the winding shaft, and the other end is fixed on the support. When the electric control box is opened or closed, the winding shaft can rotate synchronously, so that the length of the electric wire can increase or shorten synchronously with the opening and closing degree of the electric control box.

[0034] When the electric control box is opened, the electric wire drives the winding shaft to rotate under the action of the rotational force of the electric control box, so that the length of the electric wire can increase synchronously with the opening and closing degree of the electric control box. In this process, the spring will be twisted and compressed due to the inability to rotate synchronously; when the electric control box is closed, the spring will drive the winding shaft to rotate in the opposite direction in order to restore the deformation, so that the length of the electric wire can be shortened synchronously with the opening and closing degree of the electric control box, thereby realizing the automatic retraction and release of the electric wire.

[0035] An air conditioner comprises the above-mentioned electric control box installation structure.

[0036] In summary, the electric control box installation structure and the air conditioner described in the present application have the advantages of simple structure, stable installation of the electric control box, convenient opening and closing, easy maintenance, and high aesthetics.

[0056] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0057] Example 1

[0058] like Figures 1 to 17 As shown, an electric control box installation structure includes an electric control box 1 and a middle frame 2, an end cover 21 is provided at the end of the middle frame 2, a partial area of ​​the end cover 21 is hollowed out to form a mounting opening 22 of the electric control box 1, one side of the electric control box 1 is rotatably mounted on the mounting opening 22, and the other side is detachably connected to the middle frame 2 through a fixed connection structure.

[0059] Furthermore, a rotating shaft 13 and the fixed connection structure are respectively provided on two opposite sides of the electric control box 1, one side of the electric control box 1 is rotatably mounted on the mounting opening 22 via the rotating shaft 13, and the opposite side is detachably connected to the middle frame 2 via the fixed connection structure.

[0060] To clearly describe this application, Figure 1 As shown, in this application Figure 1 The positive direction of the X-axis is called "down" and the negative direction is called "up". Figure 1 The positive direction of the Y axis is called "front" and the negative direction is called "back". Figure 1 The positive direction of the Z axis is called "right" and the negative direction is called "left".

[0061] Preferably, when the air conditioner is installed, in the use state of the air conditioner, the rotating shaft 13 is arranged on the middle frame 2 in the horizontal direction, and the fixed connection structure is located on the upper side of the electric control box 1, and the rotating shaft 13 is located on the lower side of the electric control box 1. In this way, the process of rotating and opening the electric control box 1 is: first open the fixed connection structure located on the upper side of the electric control box 1, and then rotate the electric control box 1 downward so that the electric control box 1 can move around the rotating shaft 13 in a vertical plane, and finally rotate to the set position and then fully open.

[0062] More preferably, Figure 1 As shown, the electric control box 1 can rotate around the rotation axis 13 in a vertical plane to a horizontal position and then stop. This allows the electric control box 1 to be horizontally fixed at one end of the middle frame 2 when the electric control box 1 is in an open state. The maintenance personnel do not need to open the front panel, middle frame 2 or base 3 of the air conditioner, nor do they need to completely remove the electric control box 1 or hold the electric control box 1. They only need to rotate and open the electric control box 1 to repair the electric control box 1. The whole process is simple, convenient and fast.

[0063] The electric control box installation structure described in the present application makes the opening and closing of the electric control box 1 convenient and the maintenance process simple by setting the electric control box 1 to be rotated to open; in addition, the setting of the fixed connection structure makes the installation of the electric control box 1 stable, and it will not be opened at will during the use of the air conditioner without human operation.

[0064] Furthermore, the electric control box 1 comprises a box body 11 and a cover plate 12, wherein the cover plate 12 covers one side of the box body 11. Figure 1 and 2 As shown, when the electric control box 1 is in a closed state, the cover plate 12 covers the installation opening 22, and the cover plate 12 and the end cover 21 together form the end surface of the middle frame 2, and the box body 11 is located inside the middle frame 2, so that the electric control box 1 has good sealing performance, is not easily damaged, and is not easily entered by dust, insects, and mice; and the installation structure of the electric control box has a high aesthetic level.

[0065] Preferably, the shape of the cover plate 12 is set to correspond to the shape of the end cover 21 before being hollowed out, so that the cover plate 12 can cooperate with the outer surface of the end cover 21 to jointly form a smoothly transitioned end face of the middle frame 2. Ultimately, when the electric control box 1 is in a closed state, the end face of the middle frame 2 is consistent with the appearance of the end cover 21 before being hollowed out, further improving the aesthetics of the electric control box installation structure.

[0066] Furthermore, the fixed connection structure is respectively arranged on the electric control box 1, the end cover 21 and the base 3, and the electric control box 1 is respectively connected to the end cover 21 and the base 3 through the fixed connection structure, so that the electric control box 1, the end cover 21 and the base 3 can be mutually connected, supported and fixed through the fixed connection structure, so that the electric control box 1, the end cover 21 and the base 3 can form a whole with strong connection stability.

[0067] As some embodiments of the present application, Figures 2 to 9As shown, the fixed connection structure includes a first fixed connection hole 24, a second fixed connection hole 31, a third fixed connection hole 14 and a fourth fixed connection hole 15, wherein the first fixed connection hole 24 is arranged on the base 3, the second fixed connection hole 31 is arranged on the end cover 21, and the third fixed connection hole 14 and the fourth fixed connection hole 15 are arranged on the cover plate 12. When the electric control box 1 is in a closed state, the first fixed connection hole 24 can overlap with the third fixed connection hole 14 and be detachably connected by screws and other components; the second fixed connection hole 31 can overlap with the fourth fixed connection hole 15 and be detachably connected by screws and other components.

[0068] Preferably, Figures 3-4 As shown, part of the end cover 21 is recessed toward the interior of the middle frame 2 to form a sink 23, and the first fixed connection hole 24 is formed on the sink 23; correspondingly, as shown Figure 2 As shown, the third fixed connection hole 14 is located on the cover plate 12, and when the cover plate 12 is covered on the installation opening 22, part of the cover plate 12 can be accommodated in the sink 23, so that the cover plate 12 and the end cover 21 are installed together in an alternating and overlapping manner through the sink 23, further improving the sealing performance of the electric control box 1, the aesthetics of the electric control box installation structure and the connection stability between the cover plate 12 and the end cover 21.

[0069] Preferably, Figures 7-8 As shown, the second fixed connection hole 31 is formed by a screw column arranged on one side of the base 3, and the inner side of the cover plate 12 can be supported by the screw column, so that the connection stability between the cover plate 12 and the base 3 is stronger.

[0070] Furthermore, one end of the rotating shaft 13 is connected to the middle frame 2, and the other end is connected to the base 3, so that the electric control box 1, the end cover 21 and the base 3 can be further interconnected, supported and fixed through the rotating shaft 13, so that the electric control box 1, the end cover 21 and the base 3 can form a whole and the connection stability is stronger.

[0071] As some embodiments of the present application, Figures 5-6 As shown, a first rotating connection hole 26 is provided on the inner side of the end cover 21, and one end of the rotating shaft 13 is inserted into the first rotating connection hole 26 to realize the rotatable connection between the electric control box 1 and the middle frame 2. Preferably, the first rotating connection hole 26 is formed on a mounting seat 25 on the inner side of the end cover 21, and the mounting seat 25 is a boss provided on the inner side of the end cover 21, and the mechanical strength of the first rotating connection hole 26 can be improved by the mounting seat 25.

[0072] As some embodiments of the present application, Figures 9-10 As shown, a second rotation connection hole 32 is provided on one side of the base 3 , and the other end of the rotation shaft 13 can be inserted into the second rotation connection hole 32 , so as to realize a rotatable connection between the electric control box 1 and the base 3 .

[0073] Further, such as Figures 9 to 12 As shown, a limit platform 33 is also provided on the base 3, and the limit platform 33 is a protrusion provided at the end of the base 3. When the electric control box 1 is rotated and opened to a horizontal position, the cover plate 12 can be tightly attached to one side surface of the limit platform 33, so that the electric control box 1 cannot continue to rotate.

[0074] Further, such as Figures 13 to 17 As shown, the installation structure of the electric control box also includes a winding structure 4, which includes a winding shaft 42 and an electric wire 44 wound on the winding shaft 42. By rotating the winding shaft 42, the length of the electric wire 44 can be increased or shortened.

[0075] Specifically, when the electric control box 1 is opened, the length of the electric wire 44 can be increased by rotating the winding shaft 42 in a clockwise or counterclockwise direction; when the electric control box 1 is closed, the length of the electric wire 44 can be shortened by rotating the winding shaft 42 in the opposite direction. In this way, the electric wire 44 can be timely retracted and released, avoiding the electric wire 44 from being broken due to pulling when the electric control box 1 is opened or the excess electric wire 44 from being unable to be retracted in time and being tangled in a mess inside the electric control box 1 when the electric control box 1 is closed.

[0076] Furthermore, if Figures 13 to 17 As shown, the winding structure 4 also includes a support 41, and the support 41 is formed on the inner side of the end cover 21. A bayonet is provided on the support 41, and the two ends of the winding shaft 42 are respectively inserted into the bayonet on the two supports 41, and the winding shaft 42 can rotate in the bayonet. When the winding shaft 42 is rotated, the length of the wire 44 can be increased or shortened. As some embodiments of the present application, the bayonet can be a C-shaped or U-shaped structure.

[0077] Furthermore, a spring 43 is sleeved on the winding shaft 42, one end of the spring 43 is fixed to the winding shaft 42 by a first spring fixing portion 45, and the other end is fixed to the support 41 by a second spring fixing portion 46. When the electric control box 1 is opened, the electric wire 44 drives the winding shaft 42 to rotate under the action of the rotational force of the electric control box 1, so that the length of the electric wire 44 can increase synchronously with the opening and closing degree of the electric control box 1. In this process, the spring 43 will be twisted and compressed due to the inability to rotate synchronously; when the electric control box 1 is closed, the spring 43 will drive the winding shaft 42 to rotate in the opposite direction due to the need to restore the deformation, so that the length of the electric wire 44 can be shortened synchronously with the opening and closing degree of the electric control box 1.

[0078] Preferably, limiting rings 47 are provided at both ends of the winding shaft 42. The limiting rings 47 are annular protrusions arranged at both ends of the winding shaft 42. When the winding shaft 42 is installed in the support 41, the two limiting rings 47 are respectively located on one side of the two supports 41, and the limiting rings 47 can be used to limit the axial direction of the winding shaft 42.

[0079] As some embodiments of the present application, the first spring fixing portion 45 is a fixing hole formed on the winding shaft 42 ; the second spring fixing portion 46 is a U-shaped snap-fit ​​structure arranged on one side of the support 41 .

[0080] Furthermore, the elastic coefficient of the spring 43 is selected according to the gravity of the electric control box 1, so that the gravity of the electric control box 1 after opening is greater than the elastic force of the spring 43, so that the electric control box 1 does not rebound and the wire 44 is not damaged when it is pulled.

[0081] In addition, the present application also provides an air conditioner having the above-mentioned electric control box installation structure.

[0082] In summary, the electric control box installation structure and the air conditioner described in the present application have the advantages of simple structure, stable installation of the electric control box, convenient opening and closing, easy maintenance, and high aesthetics.
