Alternatively, the electronic control component is disposed on an electronic control board and is assembled in the master unit. In related technologies, when facing a circuit layout with a relatively complex power consumption structure and a large number of the electronic control components, the size or number of the corresponding electronic control boards will be increased. Multiple brackets are required to install and fix the electronic control boards in the master unit. However, the current way of assembling the electronic control boards takes up a large space, leading to a difficult layout.

[0003] EP2481994B1 discloses outdoor unit of an air conditioner for facilitating setting of an electrical component box into the outdoor unit.SUMMARY

[0004] The main purpose of the invention is to provide an electronic control component, an air-conditioning outdoor unit and an air conditioner, aiming to solve the technical problem that assembling the electronic control boards takes up a large space, resulting in difficult layout. The invention is set out in the appended set of claims.

[0005] In order to achieve the above purpose, the invention provides an electronic control component. The electronic control component includes a mounting bracket and a plurality of electronic control circuit boards. The mounting bracket includes a first mounting plate, a second mounting plate and a support member. The plurality of electric control circuit boards are respectively provided on the first mounting plate and the second mounting plate. The first mounting plate is connected to the second mounting plate, and an included angle is formed between the first mounting plate and the second mounting plate. The support member is connected between the first mounting plate and the second mounting plate.

[0006] The beneficial effects of the invention are: the plurality of electronic control circuit boards are fixed through the first and second mounting plates that are connected to each other and their structures are strengthened using the support member, thereby ensuring a mounting reliability of the electronic control circuit boards, reducing an overall space occupied by the electronic control component.

[0007] On the basis of the above technical solution, the invention may be further improved as follows.

[0008] Further, one side edge of the first mounting plate is connected to one side edge of the second mounting plate. A first end of the support member is connected to the other side edge of the first mounting plate that is farther away from the second mounting plate than the one side edge of the first mounting plate. A second end of the support member is connected to the other side edge of the second mounting plate that is farther away from the first mounting plate than the one side edge of the second mounting plate. Such a configuration may improve the reliability of the support structure.

[0009] Further, a surface of the first mounting plate is perpendicular to a surface of the second mounting plate, and the support member forms a triangular support structure with the first mounting plate and the second mounting plate. Such a configuration may improve the overall structural strength of the mounting bracket.

[0010] Further, one of the one side edge of the first mounting plate and the one side edge of the second mounting plate is provided with at least one slot, and the other one of the one side edge of the first mounting plate and the one side edge of the second mounting plate is provided with at least one buckle, and the buckle is engaged in the slot. Such a configuration may improve the convenience for assembling the first mounting plate and the second mounting plate.

[0011] Further, a plurality of buckles and slots may be disposed, and the plurality of buckles correspond to the plurality of slots one by one, and the plurality of buckles and the plurality of slots are respectively arranged at intervals along extending directions of the one side edge of the first mounting plate and of the one side edge of the second mounting plate. Such a configuration may ensure that all positions of the one side edges of the first mounting plate and of the second mounting plate that are connected to each other can maintain an effective and reliable connection.

[0012] Further, the support member may include a support section and two connection sections. The two connection sections are respectively connected to two ends of the support section. The other side edge of the first mounting plate and the other side edge of the second mounting plate are each provided with a flange. The two connection sections are respectively connected to the flange of the first mounting plate and the flange of the second mounting plate. Such a configuration may facilitate the assembling of the support member with the first mounting plate and the second mounting plate.

[0013] Further, the connection section is provided with a plug-in portion, the flange is provided with a socket, and the plug-in portion may pass through the socket and is folded toward a direction away from an inner wall of the socket. With such a configuration, the support member may be positioned upon assembling the support member with the first mounting plate or the second mounting plate.

[0014] Further, the connection section has a first bending portion extending in a horizontal direction, and a side edge of the flange has a second bending portion extending in the horizontal direction. The first bending portion may be located above the second bending portion and abut with the second bending portion. As a result, the flange plays a load-bearing role on the support member.

[0015] Further, the plurality of electric control circuit boards may include a first electric control board, a second electric control board, a third electric control board and a radiator. The first electric control board may be located on a side of the first mounting plate facing the second mounting plate, the radiator may be located on a side of the first mounting plate away from the second mounting plate, and the second electronic control board and the third electronic control board may be located on opposite sides of the second mounting plate. With such a configuration, the assembly space on the first mounting plate and the second mounting plate may be fully utilized.

[0016] The invention further provides an air-conditioning outdoor unit. The air-conditioning outdoor unit includes a casing, a middle partition, a fan component, a compressor component and the electronic control component in the above technical solutions.

The fan component is disposed in the first accommodation chamber, and the compressor component is disposed in the second accommodation chamber. The electronic control component may be installed on a side of the middle partition facing the second accommodation chamber. Such a configuration may make full use of the space inside the casing and improve space utilization.

[0017] Further, the electronic control component may include a first mounting plate and a second mounting plate that are connected to each other. A gap is disposed at a top of the middle partition and extends along a height direction of the middle partition. The first mounting plate is plugged into the gap from top to bottom. The second mounting plate extends in a direction away from the middle partition. With such a configuration, an installation guidance of the first mounting plate may be improved, thereby improving the convenience of assembling the electronic control component and the middle partition.

[0018] Further, opposite sides of the gap may be each provided with a first folded edge, which extends along an edge of the gap. A side of the first mounting plate facing the middle partition has a protruding portion, and a shape of the protruding portion matches with a shape of the gap, and a side edge of the protruding portion abuts with the first folded edge. With such a configuration, it is possible to delimit left and right positions of the first mounting plate, thereby preventing the first mounting plate from shaking significantly relative to the gap.

[0019] Further, the electronic control component may include a radiator disposed on the protruding portion, and at least part of the radiator extends into the first accommodation chamber. With such a configuration, a heat dissipation speed of the radiator may be accelerated through the fan component in the first accommodation chamber, thereby improving heat dissipation effect.

[0020] Further, a top side of the middle partition may be provided with a second folded edge, and a top side of the first mounting plate may be provided with a hooking portion abutted with the second folded edge. With such a configuration, the middle partition may support the first mounting plate.

[0021] Further, a third folded edge may be disposed at a bottom of the gap and a limiting portion may be disposed at a bottom of the first mounting plate and abuts with the third folded edge. With such a configuration, the bottom of the first mounting plate may be supported and fixed.

[0025] In related technologies, the interior of a master unit casing of electrical devices such as an air conditioner and a warm air blower is provided with an electronic control component for controlling startup and operation of the devices. The electronic control component may be disposed in an electric control box, which is installed as a whole inside the master unit. Alternatively, the electronic control component is disposed on an electronic control board and is assembled in the master unit. The electric control box occupies a large space, so the electric control board will be assembled directly into the casing of the master unit for many small-sized master units. Facing a circuit layout with a relatively complex electricity consumption structure and a large number of the electronic control components, the size or number of the corresponding electronic control boards will be increased. Multiple brackets are required to install and fix the electronic control boards in the master unit. For example, in a three-phase electric control (380V) layout, a circuit mechanism of the three-phase circuit is more complex, which needs more electric control circuit boards to be fixed. However, the current way of assembling the electronic control boards takes up a large space. Setting up multiple electric control circuit boards separately will occupy the layout space of the fan and compressor pipelines in the master unit, resulting in low space utilization and difficulty in overall layout.

[0026] In view of this, in the electronic control component of an example of the invention, a plurality of electronic control boards may be fixed simultaneously through a structural design of a mounting bracket, and the edge space inside the master unit may be fully utilized. While ensuring permanent convenience and reliability, the space occupied is reduced in the master unit and the space utilization is improved, thereby facilitating the arrangement of other components, and improving a layout convenience.

[0027] The technical solutions of the invention will be clearly and completely described below with reference to the accompanying drawings of the invention. Obviously, the described examples are only some of the examples, rather than all of the examples in the invention. Based on the examples in the invention, all other examples obtained by those skilled in the art without creative efforts fall within the protection scope of the invention.

[0028] FIG. 1 is a schematic structural diagram of an electronic control component provided by an example of this application. FIG. 2 is a schematic structural diagram of an electronic control component provided by an example of this application viewed from another perspective.

[0029] As shown in FIG. 1 and FIG. 2, this example provides an electronic control component 100. The electronic control component 100 includes a mounting bracket 110 and a plurality of electronic control circuit boards 120. The electronic control component 100 may be applied in an air-conditioning outdoor unit. When the electronic control component 100 is assembled, the mounting bracket 110 may be connected to the air-conditioning outdoor unit. The plurality of electronic control circuit boards 120 may be installed on the mounting bracket 110. Circuit elements may be provided on the electronic control circuit board 120 to control the operation of the air-conditioning outdoor unit.

[0030] The mounting bracket 110 includes a first mounting plate 111, a second mounting plate 112 and a support member 113. The plurality of electronic control circuit boards 120 are respectively installed on the first mounting plate 111 and the second mounting plate 112. The first mounting plate 111 and the second mounting plate 112 are connected to each other, and an included angle is formed between the first mounting plate 111 and the second mounting plate 112. The support member 113 is connected between the first mounting plate 111 and the second mounting plate 112 to support and stabilize a connection between the first mounting plate 111 and the second mounting plate 112.

[0031] It may be understood that in the example of this application, the plurality of electronic control circuit boards 120 are fixed through the first mounting plate 111 and the second mounting plate 112 that are connected to each other, and the support member 113 is configured to strengthen the structure, thereby ensuring the installation reliability of the electronic control circuit boards 120. Meanwhile, the included angle is formed between the first mounting plate 111 and the second mounting plate 112. When laying out components in the air-conditioning outdoor unit, it is possible to avoid other components in the air-conditioning outdoor unit, thereby making full use of edge gaps in the air-conditioning outdoor unit, reducing the overall space occupied by the electronic control component 100 and improving the layout convenience.

[0032] It should be noted that the first mounting plate 111 may contain materials including but not limited to metals, such as iron and aluminum, or their alloys, or plastics, etc. Correspondingly, the first mounting plate 111 may be formed by plate process molding or injection molding. The second mounting plate 112 and the support member 113 may contain similar materials or use similar molding modes as the first mounting plate 111, which are not specifically limited in the example of this application.

[0033] One side edge of the first mounting plate 111 is connected to one side edge of the second mounting plate 112, and a first end of the support member 113 may be connected to the other side edge of the first mounting plate 111. The other side edge of the first mounting plate 111 is farther away from the second mounting plate 112 than the one side edge of the first mounting plate 111. A second end of the support member 113 may be connected to the other side edge of the second mounting plate 112. The other side edge of the second mounting plate 112 is farther away from the first mounting plate 111 than the one side edge of the second mounting plate 112. Therefore, the reliability of the support structure is improved.

[0034] It may be understood that the first mounting plate 111 may have a same or similar size as the second mounting plate 112; or, when there is a difference in size between the first mounting plate 111 and the second mounting plate 112, a top side of the first mounting plate 111 is approximately aligned with a top side of the second mounting plate 112. When the first mounting plate 111 and the second mounting plate 112 are disposed in the air-conditioning outdoor unit, plate surfaces of the two have different orientations to utilize the gaps at different positions in the internal space of the air-conditioning outdoor unit. When the support member 113 is connected with the first mounting plate 111 and the second mounting plate 112, the support member 113 may be disposed on a top of the first mounting plate 111 and a top of the second mounting plate 112. In this way, the main space located between the first mounting plate 111 and the second mounting plate 112 is left empty to facilitate the arrangement of other components.

[0035] Exemplarily, the surface of the first mounting plate 111 and the surface of the second mounting plate 112 may be perpendicular to each other, that is, the first mounting plate 111 and the second mounting plate 112 form a cantilever structure relative to each other. Two ends of the support member 113 are connected to two side edges, which are away from each other, of the first mounting plate 111 and of the second mounting plate 112, respectively. The support member 113 may form a triangular support structure together with the first mounting plate 111 and the second mounting plate 112, thereby improving the overall structural strength of the mounting bracket 110.

[0036] It should be noted that the included angle between the first mounting plate 111 and the second mounting plate 112 may be adapted to the layout scenario of the air-conditioning outdoor unit, and may have different angles according to different application scenarios. For example, the angles used may include 30°, 60°, 90°, etc., which is not specifically limited in the examples of this application.

[0037] In addition, a bending technology for sheet metal may be configured for molding the first mounting plate 111 and the second mounting plate 112. Alternatively, the two mounting plates may be formed independently and assembled through welding connection or detachable connection. Taking the detachable connection as an example, a specific connection between the first mounting plate 111 and the second mounting plate 112 is described.

[0038] FIG. 3 is a schematic structural diagram of position A in FIG. 1. Continuing referring to FIG. 1 to FIG. 3, in a possible implementation, one of the one side edge of the first mounting plate 111 and the one side edge of the second mounting plate 112 is provided with a slot 1111, and the other one of the one side edge of the first mounting plate 111 and the one side edge of the second mounting plate 112 is provided with a buckle 1121, and the buckle 1121 is engaged in the slot 1111, thereby improving the convenience for assembling the first mounting plate 111 and the second mounting plate 112.

[0039] It may be understood that the first mounting plate 111 may be provided with the slot 1111 and the second mounting plate 112 may be provided with the buckle 1121; or, the first mounting plate 111 may be provided with the buckle 1121 and the second mounting plate 112 may be provided with the slot 1111; or, each of the first mounting plate 111 and the second mounting plate 112 is provided with the slot 1111 and the buckle 1121, provided that the slot 1111 corresponds to the buckle 1121.

[0040] Exemplarily, when the first mounting plate 111 is provided with the slot 1111 and the second mounting plate 112 is provided with the buckle 1121, the first mounting plate 111 may function to suspend and support the second mounting plate 112. For the sake of the buckle 1121 being inserted into the slot 1111, the slot 1111 may have a length greater than the buckle 1121. Further, in order to prevent the first mounting plate 111 and the second mounting plate 112 from shaking relative to each other, the one side edge of the first mounting plate 111 and the one side edge of the second mounting plate 112 may be each provided with a folded edge for butting. The folded edges of the two may be provided with mounting holes, and the first mounting plate 111 and the second mounting plate 112 may be fixed reliably by a threaded connector passing through the mounting holes of the folded edges of the first mounting plate 111 and the second mounting plate 112.

[0041] In some examples, there may be a plurality of buckles 1121 and a plurality of slots 1111. The plurality of buckles 1121 and the plurality of slots 1111 correspond one-to-one, and are arranged at intervals respectively along extending directions of the side edges of the first mounting plate 111 and the second mounting plate 112, thereby ensuring that an effective and reliable connection may be maintained at each position of the side edges of the first mounting plate 111 and the second mounting plate 112 that are connected to each other.

[0042] It may be understood that the number of the buckles 1121 and the slots 1111 may be two, three or more. During the assembly process, the first mounting plate 111 and the second mounting plate 112 may be connected and fixed, and then either the first mounting plate 111 or the second mounting plate 112 may be installed with an inner wall or an internal structural member of the air-conditioning outdoor unit.

[0043] A specific connection mode between the support member 113 and the first mounting plate 111 and the second mounting plate 112 will be described in detail below.

[0044] FIG. 4 is a schematic structural diagram of position B in FIG. 2. Referring to FIG. 1, FIG. 2 and FIG. 4, the support member 113 includes a support section 1131 and two connection sections 1132. The two connection sections 1132 are respectively connected to both ends of the support section 1131. Each of the other side edge of the first mounting plate 111 and the other side edge of the second mounting plate 112 is provided with a flange 114. The two connection sections 1132 are connected respectively to the flanges 114 of the first mounting plate 111 and of the second mounting plate 112, thereby facilitating the assembling of the support 113 with the first mounting plate 111 and the second mounting plate 112.

[0045] It may be understood that the two connection sections 1132 may be connected to the first mounting plate 111 and the second mounting plate 112 in a similar manner, one of which is illustrated below by way of example.

[0046] In some examples, the connection section 1132 has a plug-in portion 1133, and the flange 114 may be provided with a socket 1141. The plug-in portion 1133 may pass through the socket 1141 and be folded toward a direction away from an inner wall of the socket 1141, so that when the support member 113 is assembled with the first mounting plate 111 or the second mounting plate 112, the support member 113 is positioned.

[0047] It may be understood that the socket 1141 may be connected to opposite sides of the flange 114, and the plug-in portion 1133 may penetrate from one side of the socket 1141 to the other side of the socket 1141. During assembly, the plug-in portion 1133 may be inserted into the socket 1141 from top to bottom, and its connecting end may be overlapped on the flange 114. For the sake of plugging, the size of socket 1141 may be larger than that of the plug-in portion 1133.

[0048] In addition, the connection section 1132 may be provided with a first bending portion 1134 extending in a horizontal direction, and a side edge of the flange 114 may be provided with a second bending portion 1142 extending in a horizontal direction. The first bending portion 1134 may be located above the second bending portion 1142 and abut with the second bending portion 1142, so that the flange 114 plays a load bearing role for the support member 113. Opposite mounting holes may be respectively disposed in the first bending portion 1134 and the second bending portion 1142, and the first bending portion 1134 and the second bending portion 1142 may be fixed with a threaded connector passing through the mounting holes of the first bending portion 1134 and the second bending portion 1142, so that the support member 113 is fixed to the first mounting plate 111 and the second mounting plate 112.

[0049] It should be noted that, during assembly, the first mounting plate 111 and the second mounting plate 112 may be connected to each other firstly, and then the plug-in portion 1133 is inserted into the socket 1141 to complete a positioning of the support member 113 between the first mounting plate 111 and the second mounting plate 112, followed by connecting the first bending portion 1134 and the second bending portion 1142.

[0050] In some examples, the plurality of electric control circuit boards 120 may include a first electric control board 121, a second electric control board 122, and a third electric control board 123. The electronic control component 100 may further include a radiator 124. The first electric control board 121 may be located on a side of the first mounting plate 111 facing the second mounting plate 112. The radiator 124 may be located on a side of the first mounting plate 111 away from the second mounting plate 112. The second electric control board 122 and the third electric control board 123 may be respectively located on two opposite sides of the second mounting plate 112, which may fully utilize the assembly spaces on the first mounting plate 111 and the second mounting plate 112.

[0051] It may be understood that the radiator 124 may dissipate heat for the plurality of electronic control circuit boards 120 when the electronic control component 100 works. The first electronic control board 121 and the radiator 124 are provided on opposite sides of the first mounting plate 111, and the radiator 124 has a better heat dissipation effect for the first electric control board 121. Therefore, the first electric control board 121 may be provided with electronic components that generate high heat.

[0052] It should be noted that the electronic components on the electronic control circuit board 120 may include capacitors, resistors, processors, memory and other components, fuse, filter, etc. Different electronic components may be connected by cables according to the design of circuit. The specific circuit layout and functions of the electronic control circuit board 120 are not limited in the example of this application.

FIG. 6 is a schematic diagram of the internal structure of the air-conditioning outdoor unit provided by an example of this application viewed from another perspective. FIG. 7 is a schematic assembly diagram of the electronic control component and the middle partition of the air-conditioning outdoor unit provided by an example of this application. FIG. 8 is a schematic structural diagram of position C in FIG. 7.

[0054] Referring to FIG. 5 to FIG. 8, the application further provides an air-conditioning outdoor unit. The air-conditioning outdoor unit includes a casing 200, a middle partition 300, a fan component 400, a compressor component 500 and the electronic control component 100 in the above technical solutions. The middle partition 300 may be disposed inside the casing 200 and divide the interior of the casing 200 into a first accommodation chamber 210 and a second accommodation chamber 220. The fan component 400 is disposed in the first accommodation chamber 210. The compressor component 500 is disposed in the second accommodation chamber 220. The electronic control component 100 may be disposed on a side of the middle partition 300 facing the second accommodation chamber 220, thereby fully utilizing the space inside the casing 200 and improving space utilization.

[0055] It may be understood that a fan of the fan component 100 in the first accommodation chamber 210 has a large rotation space. Comparatively speaking, pipes of the compressor component 500 are mainly disposed in the second accommodation chamber 220, where the usable gap space is larger. Exemplarily, a compressor may be arranged in a lower portion of the second accommodation chamber 220, and the electronic control component 100 may be arranged in an upper portion of the second accommodation chamber 220. Other electronic control components may also be provided in the air-conditioning outdoor unit.

[0056] The electronic control component may include a reactance component, which includes a three-phase reactor 600 and a holder 700. The three-phase reactor 600 is disposed on the first mounting plate 111 or the second mounting plate 112 through the holder 700.

[0057] Exemplarily, in a solution of three-phase electric control, there may also be a three-phase reactor 600. The three-phase reactor 600 may be separately provided at an upper end of the middle partition 300 at its side facing the first accommodation chamber 210 by means of the holder 700.

[0058] In some examples, the electronic control component 100 may include the mounting bracket 110 and an electric control circuit board 120 disposed on the mounting bracket 110. The electric control circuit board 120 may control the operation of the fan component 400 and the compressor component 500. The mounting bracket 110 includes the first mounting plate 111 and the second mounting plate 112 that are connected to each other. A gap 301 may be disposed at a top of the middle partition 300. The gap 301 extends along a height direction of the middle partition 300. The first mounting plate 111 is inserted into the gap 301 from top to bottom, that is, along the X direction in FIG. 7. The second mounting plate 112 extends in a direction away from the middle partition 300, which may improve the installation guidance for the first mounting plate 111, thereby improving the assembling convenience between the electronic control component 100 and the middle partition 300.

[0059] It may be understood that the first mounting plate 111 corresponds to a plate surface of the middle partition 300 facing the second accommodation chamber 220, and the second mounting plate 112 corresponds to an inner wall of the second accommodation chamber 220 at its side. The support member 113 may be located on a top of the second accommodation chamber 220 and connect with the first mounting plate 111 and the second mounting plate 112, so that the entire electronic control component 100 may kept away from pipelines of the compressor component 500 in the second accommodation chamber 220.

[0060] The butting mode of the first mounting plate 111 and the middle partition 300 will be described in detail below.

[0061] Referring to FIG. 5 to FIG. 8, in a possible implementation, two opposite sides of the gap 301 are provided with first folded edges 310, which may extend along the edge of the gap 301 so as to define a moving track from top to bottom in the gap 301. A protruding portion 1112 is disposed at a side of the first mounting plate 111 facing the middle partition 300. A shape of the protruding portion 1112 matches with a shape of the gap 301, and side edges of the protruding portion 1112 abuts with the first folded edges 310. When the first mounting plate 111 is installed on the middle partition 300, the protruding portion 1112 may move along the first folded edges 310. In this way, the left and right positions of the first mounting plate 111 are delimited to prevent the first mounting plate 111 from shaking sharply relative to the gap 301.

[0062] It may be understood that the radiator 124 of the electronic control component 100 may be disposed on the protruding portion 1112, and at least part of the radiator 124 extends into the first accommodation chamber 210, so that the heat dissipation speed of the radiator 124 may be accelerated by the fan component 400 in the first accommodation chamber 210, thereby improving the heat dissipation effect.

[0063] Exemplarily, the protruding portion 1112 may be square, and each corner of the protruding portion 1112 may be chamfered to facilitate processing and shaping. The protruding portion 1112 may also have a shape including but not limited to circle, ellipse, or other regular shapes, which is not specifically limited in the examples of this application.
