Description

Technical Field

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

[0002] In existing air conditioners, an electrical control box is usually required to accommodate and install various electrical components. Since a large number of electrical components are installed in the electrical control box, which is directly related to whether the air conditioner can operate normally, the installation stability of the electrical control box is required to be high to prevent the electrical control box from being installed unstable, causing jitter or deviation during use, affecting the stable connection and normal operation of the various electrical components in the electrical control box.

[0003] In addition, since a large number of electrical components are integrated inside the electric control box, the failure rate of the electric control box is extremely high. Therefore, the requirements for the convenience of disassembly and assembly of the electric control box are also high. The electric control box must be easy to disassemble and assemble to facilitate maintenance.

[0004] Therefore, providing an electric control box and an air conditioner that are stable to install and easy to assemble and disassemble is one of the technical problems that need to be solved urgently by those skilled in the art. Summary of the Invention

[0005] The present invention designs an electric control box and an air conditioner to achieve the purpose of stable installation and convenient assembly and disassembly of the electric control box and the air conditioner.

[0006] To solve the above problems, the present invention discloses an electric control box, comprising a box body and a box cover, wherein the box cover is covered on the box body, and the box body is mounted on a back plate, a cut tongue is provided on the back plate, and a snap-in hole is provided on the box body, wherein the cut tongue can be inserted into the snap-in hole to mount the box body on the back plate.

[0007] The electric control box described in the present application realizes rapid assembly of the electric control box and the back plate through the cut-out tongue located on the back plate and the snap-in hole located on the box body. It not only has a simple structure and a stable connection, but also has a quick assembly process, which is conducive to the stable installation and repeated rapid disassembly of the electric control box.

[0008] Furthermore, a portion of the back plate protrudes toward a side close to the box body to form a limiting seat, and the cut tongue is formed by bending and tilting a portion of the limiting seat.

[0009] The limit seat is formed by protruding a partial area of the back plate, so that the limit seat can be prepared with the back plate through integral molding. Compared with manufacturing the limit seat separately and then assembling it to the back plate, the limit seat of the present application is more convenient to prepare, and the connection between the limit seat and the back plate is more stable and firm, which is conducive to improving the installation stability of the electric control box.

[0010] Furthermore, a guide surface is provided on the limiting seat, and the guide surface is tilted along the direction in which the box body slides and inserts into the cutting tongue.

[0011] The provision of the guide surface enables the cut tongue on the back plate to be smoothly inserted into the clamping hole on the box body, making the assembly between the box body and the back plate more convenient.

[0012] Furthermore, the cut tongue portion is raised to form a reinforcing rib.

[0013] The reinforcing ribs can be integrally formed with the tongue, facilitating fabrication. They also effectively reinforce the tongue, improving its mechanical strength and thereby enhancing the connection between the box body and the back panel. Furthermore, they ensure a stable connection between the engaging hole and the tongue.

[0014] Furthermore, the box body includes a bottom surface and a plurality of side surfaces arranged around the bottom surface, and the engaging hole is located at the connection between the bottom surface and one of the side surfaces.

[0015] Providing the snap-fit hole at the connection between the bottom surface and one of the side surfaces not only makes it easier for the cut tongue to be inserted into the snap-fit hole, but also reduces the adverse effects of the cut tongue on the internal space of the electric control box.

[0016] Furthermore, the back plate is provided with two limiting seats, and correspondingly, the box body is provided with two clamping holes, and the two clamping holes are respectively located at two ends of the box body.

[0017] The clamping holes are respectively provided at both ends of the box body, which can reduce the number of the clamping holes and the limiting seats while ensuring the installation stability of the box body.

[0018] Furthermore, a support bar is provided on the back plate, and the support bar is formed by protruding from a part of the back plate toward a side close to the box body.

[0019] The setting of the support strip can improve the strength of the back plate on the one hand, and can support the box body on the other hand, so that the bottom surface of the box body and the root of the tongue of the cut tongue are on the same plane, making the installation of the electric control box more stable.

[0020] Furthermore, one side surface of the box body is folded outward and extended to form a first connecting surface. Correspondingly, a third connecting surface is provided on the back panel. When the cut tongue is inserted into the snap-in hole, the third connecting surface can be attached to and connected with the first connecting surface.

[0021] The connection between the third connection surface and the first connection surface further enhances the installation stability of the electric control box. Furthermore, the arrangement of the third connection surface and the first connection surface allows the connection structure between the box body and the back plate to protrude from the outside of the electric control box, better exposed to the workers' line of sight, and facilitate installation between the box body and the back plate.

[0022] An air conditioner, the back plate is fixed on the air conditioner, and the air conditioner has the above-mentioned electric control box.

[0023] In summary, the electric control box and the air conditioner described in the present application have the advantages of stable installation and convenient assembly and disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0048] 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.

[0049] Example 1

[0050] like Figures 1 to 22 As shown, an electric control box includes a box body 1 and a box cover 2, the box cover 2 is covered on the box body 1, the box body 1 is installed on the back plate 3, the back plate 3 is fixed on the air conditioner, and a plurality of limit seats 31 are provided on the back plate 3, and part of the limit seats 31 are bent and raised to form a cut tongue 312. The box body 1 is provided with a snap-in hole 162, and the cut tongue 312 can be inserted into the snap-in hole 162 to realize the connection between the box body 1 and the back plate 3.

[0051] The electric control box of the present application realizes the rapid assembly of the electric control box and the back panel 3 through the cut-out tongue 312 located on the back panel 3 and the snap-in hole 162 located on the box body 1. It not only has a simple structure and a stable connection, but also has a quick assembly process, which is conducive to the stable installation and repeated rapid disassembly of the electric control box.

[0052] Further, such as Figures 17-18 As shown, a portion of the back plate 3 protrudes toward the side close to the box body 1 to form the limiting seat 31 .

[0053] The limit seat 31 is formed by protruding a partial area of the back plate 3, so that the limit seat 31 can be prepared with the back plate 3 through integral molding. Compared with manufacturing the limit seat 31 separately and then assembling it to the back plate 3, the limit seat 31 described in the present application is more convenient to prepare, and the connection between it and the back plate 3 is more stable and firm, which is conducive to improving the installation stability of the electric control box.

[0054] Furthermore, a guide surface 311 is provided on the limiting seat 31 , and the guide surface 311 is tilted along the direction in which the box body 1 slides and inserts into the cutting tongue 312 .

[0055] The provision of the guide surface 311 enables the cut tongue 312 on the back plate 3 to be smoothly inserted into the engaging hole 162 on the box body 1 , making the assembly between the box body 1 and the back plate 3 more convenient.

[0056] Preferably, a portion of the cut tongue 312 is raised to form a reinforcing rib 313 .

[0057] More preferably, the reinforcing rib 313 extends from the root of the cut tongue 312 to the tip of the tongue.

[0058] The reinforcing rib 313 can not only be prepared by integral molding with the cutting tongue 312, which has the advantage of convenient preparation; it can also play a good reinforcing role on the cutting tongue 312, improve the mechanical strength of the cutting tongue 312, and thereby improve the connection strength between the box body 1 and the back panel 3.

[0059] Further, such as Figures 1 to 7 As shown, the box body 1 includes a bottom surface 16 and a plurality of side surfaces arranged around the bottom surface 16, and the engaging hole 162 is located at the connection between the bottom surface 16 and one of the side surfaces. Figure 6 As shown, the engaging hole 162 is partially formed on the bottom surface 16 and partially formed on one side surface of the box body 1 .

[0060] Providing the snap-fit hole 162 at the connection between the bottom surface 16 and one of the side surfaces not only makes it easier for the cut tongue 312 to be inserted into the snap-fit hole 162 , but also reduces the adverse effects of the cut tongue 312 on the internal space of the electric control box.

[0061] Furthermore, the shape and size of the engaging hole 162 should be set to correspond to the shape and size of the cutting tongue 312 so that the cutting tongue 312 can be stably connected to the engaging hole 162 .

[0062] Preferably, the engaging hole 162 is a through hole in a rectangular hole, a trapezoidal hole or the like, and correspondingly, the cutting tongue 312 is in a sheet-shaped curved shape.

[0063] Setting the engaging hole 162 as a rectangular hole or a trapezoidal hole can improve the connection stability between the engaging hole 162 and the cut tongue 312 , making it difficult for the electric control box to shake.

[0064] As some embodiments of the present application, two limiting seats 31 are provided on the back plate 3 , and correspondingly, two snap-fit holes 162 are provided on the box body 1 , and the two snap-fit holes 162 are respectively located at both ends of the box body 1 .

[0065] During assembly, first align the snap-fit hole 162 on the box body 1 with the cut tongue 312 on the limit seat 31, and then push the box body 1 toward the cut tongue 312 until the cut tongue 312 is inserted into the snap-fit hole 162, thereby completing the connection between the box body 1 and the back panel 3.

[0066] The clamping holes 162 are respectively provided at both ends of the box body 1 , which can reduce the number of the clamping holes 162 and the limiting seats 31 while ensuring the installation stability of the box body 1 .

[0067] Further, such as Figures 17-22 As shown, a support bar 33 is further provided on the back panel 3, and the support bar 33 is formed by a partial area of the back panel 3 protruding toward the side close to the box body 1. The setting of the support bar 33 can, on the one hand, improve the strength of the back panel 3, and on the other hand, support the box body 1, so that the bottom surface 16 of the box body 1 and the root of the tongue 312 are on the same plane, making the installation of the electric control box more stable.

[0068] Furthermore, the back panel 3 also includes a connecting plate 4 vertically connected thereto, and the connecting plate 4 is used to connect to other components in the air conditioner, and can also support the back panel 3, so that the connection between the back panel 3 and the air conditioner is more stable.

[0069] Example 2

[0070] In order to further achieve the purpose of stable installation and convenient assembly and disassembly of the electric control box of the present application, the structure of the electric control box of Example 1 is further optimized on the basis of Example 1. Specifically:

[0071] like Figures 1 to 7 As shown, the box body 1 includes a bottom surface 16 and a plurality of side surfaces arranged around the bottom surface 16. One side surface of the box body 1 is folded and extended outward to form a first connecting surface 15. The first connecting surface 15 is used to connect with the back plate 3.

[0072] like Figures 17-22 As shown, a third connecting surface 32 is provided on the back panel 3. When the snap-in hole 162 on the box body 1 is snapped onto the cut tongue 312, the third connecting surface 32 is fitted together with the first connecting surface 15, so that the box body 1 and the back panel 3 can be connected together through the connection between the third connecting surface 32 and the first connecting surface 15.

[0073] Preferably, the first connecting surface 15 and the engaging hole 162 are arranged on two sides of the box body 1 opposite to each other, and the third connecting surface 32 and the limiting seat 31 are arranged corresponding to the first connecting surface 15 and the engaging hole 162 respectively.

[0074] Furthermore, a fourth connection hole 321 is provided on the third connection surface 32, and the fourth connection hole 321 is a through hole. A third connection hole 152 is provided on the first connection surface 15, and the third connection hole 152 is a through hole. The fourth connection hole 321 and the third connection hole 152 can be connected by screws, bolts, rivets, etc.

[0075] The connection between the third connection surface 32 and the first connection surface 15 further enhances the installation stability of the electric control box. Furthermore, the arrangement of the third connection surface 32 and the first connection surface 15 allows the connection structure between the box body 1 and the back plate 3 to protrude from the outside of the electric control box, making it more visible to workers and facilitating installation of the box body 1 and the back plate 3.

[0076] Example 3

[0077] like Figures 1 to 22 As shown, an electric control box includes:

[0078] The box body 1 includes a bottom surface 16 and a plurality of side surfaces surrounding the bottom surface 16. One side surface of the box body 1 is folded and extended outward to form a first connecting surface 15. The first connecting surface 15 is used to connect with the box cover 2.

[0079] The box cover 2 includes a top surface 21 and a second connecting surface 23. The top surface 21 can be covered on the box body 1. When the box cover 2 is covered on the box body 1, the second connecting surface 23 and the first connecting surface 15 can at least partially overlap with each other, so that the box cover 2 and the box body 1 can be connected together through the connection between the second connecting surface 23 and the first connecting surface 15.

[0080] Preferably, the second connecting surface 23 and the first connecting surface 15 can completely overlap with each other.

[0081] Furthermore, the first connection surface 15 and the second connection surface 23 can be fixedly connected together by a detachable connection method such as screw connection, clamping, riveting, bolting, etc.

[0082] Preferably, the first connection surface 15 and the second connection surface 23 are fixedly connected by screws. The screw connection can make the first connection surface 15 and the second connection surface 23 fit tightly together, ensuring the sealing between the box body 1 and the box cover 2.

[0083] Specifically, a first connection hole 151 is provided on the first connection surface 15 , and a second connection hole 231 is provided on the second connection surface 23 . Screws pass through the first connection hole 151 and the second connection hole 231 to fix the first connection surface 15 and the second connection surface 23 together.

[0084] Furthermore, an avoidance groove 232 is further provided on the second connection surface 23 . The avoidance groove 232 is provided corresponding to the third connection hole 152 , so that the third connection hole 152 can be exposed.

[0085] First, the electric control box described in the present application extends the fixed connection structure between the box body 1 and the box cover 2 from the side wall of the electric control box through the setting of the second connection surface 23 and the first connection surface 15. Compared with the fixed connection structure that fits the side of the box body 1 or the box cover 2, or is directly set on the side of the box body 1 or the box cover 2, the operator has a larger operating space and a better field of view when installing the electric control box described in the present application, so that the operator can assemble the box body 1 and the box cover 2 together more quickly and accurately.

[0086] Furthermore, the arrangement of the second connecting surface 23 and the first connecting surface 15 extends the fixed connection structure between the box body 1 and the box cover 2 from the side wall of the electric control box. Compared with the structure of the traditional electric control box, this avoids the reduction in the sealing of the electric control box caused by directly opening connection holes and other structures on the side wall of the electric control box, thereby reducing the waterproof, dustproof and fireproof performance of the electric control box; at the same time, it also avoids the arrangement of connecting clips on the inner wall of the electric control box, which reduces the internal space of the electric control box and affects the distribution and installation of electrical components inside the electric control box.

[0087] In addition, the arrangement of the second connection surface 23 and the first connection surface 15 can reinforce the side of the electric control box, preventing the electric control box from shaking or deforming, and making the installation of the electric control box itself and the internal electrical components more stable.

[0088] Example 4

[0089] In order to further achieve the purpose of the electric control box of the present application having a stable structure, good sealing, and convenient assembly and disassembly, the structure of the electric control box of Example 3 is further optimized on the basis of Example 3. Specifically:

[0090] The box body 1 includes a first side surface 11 and a third side surface 13 arranged on both sides of the bottom surface 16, and a second side surface 12 and a fourth side surface 14 arranged on the other two sides of the bottom surface 16. The first side surface 11, the second side surface 12, the third side surface 13 and the fourth side surface 14 are connected in sequence to form a storage space for electrical components in the box body 1.

[0091] Furthermore, the first side surface 11, the second side surface 12, the third side surface 13, or the fourth side surface 14 extends obliquely from the bottom surface 16 toward the outside of the electric control box and is connected to the first connecting surface 15. In this way, the interior space of the electric control box can be increased while the first connecting surface 15 is arranged within the field of view that can be easily seen by the operator.

[0092] As some embodiments of this application, Figures 1 to 7 As shown, the box body 1 has a structure similar to a cube or a cuboid as a whole, the bottom surface 16 is rectangular, the first side surface 11 and the third side surface 13 are a group of side surfaces arranged perpendicular to the bottom surface 16, the second side surface 12 and the fourth side surface 14 are another group of side surfaces arranged on both sides of the bottom surface 16, the second side surface 12 is vertically connected to the bottom surface 16, the fourth side surface 14 extends obliquely from the bottom surface 16 toward the outside of the electric control box, and the first connecting surface 15 is provided on the side of the fourth side surface 14 away from the bottom surface 16, and the first connecting surface 15 extends obliquely from the fourth side surface 14 toward the outside of the electric control box.

[0093] More preferably, the included angle between the fourth side surface 14 and the bottom surface 16 is greater than 90 degrees, and the included angle between the fourth side surface 14 and the first connecting surface 15 is less than 90 degrees.

[0094] Furthermore, the side surface of the box body 1 is partially hollowed out to form through holes and / or grooves, and the through holes and / or grooves are used for wiring to achieve electrical connection between the electrical components in the electric control box and the external structure.

[0095] As some embodiments of this application, Figures 1 to 7 As shown, a wire hole 111 is provided on the first side surface 11 , and the wire hole 111 is a circular through hole formed on the first side surface 11 .

[0096] As some embodiments of this application, Figures 1 to 7 As shown, a wiring groove 131 is provided on the third side surface 13 , and the wiring groove 131 is a U-shaped groove formed on the third side surface 13 .

[0097] Further, such as Figures 1 to 7 As shown, the box body 1 is further provided with a snap-fitting groove 121 , and the snap-fitting groove 121 is used to snap-fit with the box cover 2 .

[0098] Preferably, the engaging groove 121 and the first connecting surface 15 are arranged on two sides of the box body 1 opposite to each other.

[0099] Furthermore, the engaging groove 121 is formed by bending the side surface of the box body 1 .

[0100] Preferably, the engaging groove 121 is formed by bending one side surface of the box body 1 multiple times to different degrees.

[0101] As some embodiments of the present application, a snap-in groove 121 is provided on the second side surface 12, and a first connecting surface 15 is provided on the fourth side surface 14. One side of the box cover 2 is snap-connected to the box body 1 through the snap-in groove 121, and the opposite side is connected to the box body 1 through the first connecting surface 15.

[0102] Furthermore, the engaging groove 121 is formed by bending the second side surface 12 .

[0103] Preferably, the engaging groove 121 is formed by bending the second side surface 12 multiple times to different degrees.

[0104] As some embodiments of the present application, the engaging groove 121 is formed by bending the second side surface 12 twice to different degrees.

[0105] Specifically, such as Figures 4-5 As shown, the snap-fit groove 121 has a first groove wall 121a and a second groove wall 121b that are oppositely arranged. The first groove wall 121a is formed by bending a portion of the second side surface 12, and the second groove wall 121b is formed by bending another portion of the second side surface 12. The bending degrees of the first groove wall 121a and the second groove wall 121b are different. Thus, the snap-fit groove 121 is formed between the first groove wall 121a and the second groove wall 121b. One side of the box cover 2 can be inserted into the snap-fit groove 121 to achieve the snap connection between the box cover 2 and one side of the box body 1.

[0106] The snap-fitting groove 121 has a simple structure and is easy to prepare. It can be snap-fitted with the box cover 2 quickly and is easy to assemble.

[0107] In addition, if Figures 1 to 7 As shown, a portion of the bottom surface 16 protrudes into the interior of the electrical control box to form a reactor mounting seat 161. The provision of reactor mounting seat 161 creates a clear reactor installation area, making reactor installation more accurate and rapid. Furthermore, the convex structure of reactor mounting seat 161 prevents water from accumulating, making the reactor components located thereon more waterproof.

[0108] Example 5

[0109] On the basis of Example 4, the structure of the electric control box described in Example 4 is further optimized. Specifically:

[0110] like Figures 1 to 7As shown, the first side surface 11, the second side surface 12, the third side surface 13, or the fourth side surface 14 extends obliquely from the bottom surface 16 toward the outside of the electrical control box to the middle of the box body 1 and connects to the first connecting surface 15. Because one side surface of the box body 1 only extends to the middle of the electrical control box, a notch is formed on the side surface of the electrical control box. The formation of the notch facilitates the installation of electrical components within the electrical control box. Furthermore, the formation of the first connecting surface 15 in the middle of one side of the electrical control box allows the first connecting surface 15 to reinforce the middle of the electrical control box, further enhancing the reinforcement effect of the first connecting surface 15.

[0111] Correspondingly, such as Figures 8 to 16 As shown, an inclined cover plate 22 is provided on one side of the top surface 21 of the box cover 2, one side of the inclined cover plate 22 is connected to the top surface 21, and the opposite side is connected to the second connecting surface 23, the inclined cover plate 22 is provided corresponding to the notch on the side of the electric control box, and the second connecting surface 23 is provided corresponding to the first connecting surface 15. When the box cover 2 is covered on the box body 1, the top surface 21 can cover the upper opening of the box body 1, the inclined cover plate 22 can cover the notch on the side of the box body 1, and the second connecting surface 23 can overlap with the first connecting surface 15. The connection between the box body 1 and one side of the box cover 2 is realized by the connection between the second connecting surface 23 and the first connecting surface 15.

[0112] As some embodiments of this application, Figures 1 to 16 As shown, the fourth side surface 14 extends obliquely from the bottom surface 16 toward the outside of the electrical control box to the middle of the electrical control box and is connected to the first connecting surface 15. A notch is formed on one side of the box body 1 by the fourth side surface 14, and the engaging groove 121 is provided on the second side surface 12. Correspondingly, an oblique cover plate 22 is provided on one side of the top surface 21. One side of the oblique cover plate 22 is connected to the top surface 21, and the opposite side is connected to the second connecting surface 23. The oblique cover plate 22 is positioned to correspond to the notch on the side of the electrical control box. When the box cover 2 is covered on the box body 1, the top surface 21 can cover the upper opening of the box body 1, the inclined cover plate 22 can cover the notch on the side of the box body 1, and the second connecting surface 23 can overlap and connect with the first connecting surface 15. Through the connection between the second connecting surface 23 and the first connecting surface 15, the connection between the box body 1 and one side of the box cover 2 is realized; the top surface 21 can also be inserted into the snap-fit groove 121 to realize the connection between the box body 1 and the opposite side of the box cover 2.

[0113] Further, such as Figures 8 to 16As shown, the edge of the box cover 2 is bent toward the side close to the box body 1 to form a bent wall. When the box cover 2 is placed on the box body 1, the bent wall can cover the connection between the box cover 2 and the box body 1, thereby improving the sealing performance of the electric control box. At the same time, when the box cover 2 is placed on the box body 1, it plays a guiding role, making assembly smoother.

[0114] Specifically, such as Figures 8-11 As shown, the bending wall includes a first bending wall 211 arranged on the top surface 21 and a second bending wall 221 arranged on the inclined cover plate 22, the first bending wall 211 is formed by bending the edge of the top surface 21 toward the side close to the box body 1, and the second bending wall 221 is formed by bending the edge of the inclined cover plate 22 toward the side close to the box body 1.

[0115] Furthermore, the edge of the bent wall is bent toward a side away from the box body 1 to form a flange. The flange can, on the one hand, make the assembly of the box cover 2 and the box body 1 faster, more accurate, and more secure. On the other hand, it can allow condensed water on the box cover 2 to be directly drained away through the water guide channel formed by the flange, thereby preventing the electrical components in the electric control box from getting wet.

[0116] Specifically, such as Figures 8-11 As shown, the flanges include a first flange 212 located on the first bending wall 211 and a second flange 222 located on the second bending wall 221. The first flange 212 bends from the edge of the first bending wall 211 in a direction away from the box body 1, and the second flange 222 bends from the edge of the second bending wall 221 in a direction away from the box body 1.

[0117] Furthermore, Figures 8 to 16 As shown, the flange further includes a third flange 213 located at the edge of the top surface 21, and the third flange 213 is bent from the edge of the top surface 21 in a direction away from the box body 1. The third flange 213 is used to engage with the engaging groove 121 to improve the stability of the engaging.

[0118] As some embodiments of this application, Figures 12-16 As shown, the inclined cover plate 22 and the third flange 213 are arranged on both sides of the top surface 21, and the first bent wall 211 is arranged on the other two sides of the top surface 21; the top surface 21 and the second connecting surface 23 are arranged on both sides of the inclined cover plate 22, and the second bent wall 221 is arranged on the other two sides of the inclined cover plate 22. When the box cover 2 is assembled with the box body 1, it is only necessary to Figure 10As shown, the side where the second connecting surface 23 of the box cover 2 is located faces upward and is placed correspondingly on the upper side of the box body 1, and the first bent wall 211 is aligned with the two sides of the box body 1. Then, the box cover 2 is pushed downward so that the box cover 2 slides along the box body 1 under the guidance of the first bent wall 211 until the third flange 213 is snapped into the snap-in groove 121, and then the pushing of the box cover 2 is stopped. At this time, the second bent wall 221 will naturally wrap around the side notch of the electric control box, and the second connecting surface 23 will be overlapped on the first connecting surface 15. The second connecting surface 23 and the first connecting surface 15 can be fixed together by screws through the second connecting hole 231 and the first connecting hole 151, thereby realizing the assembly of the box body 1 and the box cover 2. When the electric control box needs to be repaired, it is only necessary to remove the screws fixing the second connecting surface 23 and the first connecting surface 15 in the reverse order, and pull the box cover 2 upward until the box cover 2 is completely separated from the box body 1. The operation process is convenient and simple, and the electric control box can be disassembled and assembled repeatedly and is not easily deformed.

[0119] In addition, the top surface 21 of the box cover 2 partially protrudes toward the outside of the electric control box to form a capacitor accommodating portion 214. The capacitor accommodating portion 214 is arranged corresponding to the capacitor in the electric control box, so that the electric control box can accommodate a capacitor component with a higher height.

[0120] The present application also provides an air conditioner, which includes the above-mentioned electric control box.

[0121] Preferably, the air conditioner is a floor-mounted air conditioner, that is, an air conditioner that can be installed in a floor-mounted or ceiling-mounted manner.

[0122] In summary, it can be concluded that the electric control box and the air conditioner described in the present application have the advantages of stable installation and convenient assembly and disassembly.
