  • The technical schemes of the present disclosure will be described below with reference to the accompanying drawings and specific embodiments.
  • According to some embodiments of the present disclosure, an electronic control device and an air conditioner are provided to solve, at least to a certain extent, the technical problem that the main board 12-202 and the fan drive board 12-203 are integrated together and occupy a large space.
  • FIG. 1 is a schematic structural diagram of an electronic control device according to some embodiments of the present disclosure. FIG. 2 is an exploded view of the electronic control device shown in FIG. 1. FIG. 3 is a schematic structural diagram of an electronic control assembly in the electronic control device shown in FIG. 1. FIG. 4 is an exploded view of the electronic control assembly shown in FIG. 3. Referring to FIG. 1, FIG. 2, FIG. 3, and FIG. 4, an electronic control device according to some embodiments of the present disclosure includes an electronic control box 12-10 and an electronic control assembly 12-20. The electronic control assembly 12-20 includes an electronic control mounting member 12-218, a main board 12-202, and a fan drive board 12-203. The electronic control mounting member 12-218 is in the electronic control box 12-10. The main board 12-202 and the fan drive board 12-203 are at two opposing sides of the electronic control mounting member 12-218, respectively, and both connected to the electronic control mounting member 12-218. The main board 12-202 is electrically connected to the fan drive board 12-203.
  • The main board 12-202 may be individually arranged on a front side of the electronic control mounting member 12-218, and the fan drive board 12-203 may be individually arranged on a rear surface of the electronic control mounting member 12-218.
  • The electronic control box 12-10 includes a mounting plate 1-101 for mounting the electronic control mounting member 12-218.
  • The main board 12-202 and the fan drive board 12-203 are arranged on two opposing sides of the electronic control mounting member 12-218 along a thickness direction of the electronic control mounting member 12-218.
  • A thickness direction of the electronic control box 12-10 is the same as the thickness direction of the electronic control mounting member 12-218.
  • In the related art, the main board and the fan drive board 12-203 have to be placed in the electronic control box, i.e., the main board and the fan drive board 12-203 are accommodated in and protected by the electronic control box. However, because the main board and the fan drive board 12-203 are integrated together, i.e., the main board and the fan drive board 12-203 form an integral control component which has a large size and occupies a large space, the height of the electronic control box is limited due to the size requirement of the air conditioner, i.e., the size of the electronic control box may not meet the mounting requirement of the control component, resulting in assembly difficulties.
  • In technical schemes according to some embodiments of the present disclosure, because the electronic control assembly 12-20 includes the electronic control mounting member 12-218 arranged in the electronic control box 12-10, the main board 12-202, and the fan drive board 12-203, the electronic control box 12-10 is configured to accommodate and support the electronic control mounting member 12-218. Because the main board 12-202 and the fan drive board 12-203 are connected to the electronic control mounting member 12-218, both the main board 12-202 and the fan drive board 12-203 are supported by the electronic control mounting member 12-218 to ensure the stability of mounting of the main board 12-202 and the fan drive board 12-203 in the electronic control box 12-10. Because the main board 12-202 and the fan drive board 12-203 are on two opposing sides of the electronic control mounting member 12-218, respectively, the main board 12-202 and the fan drive board 12-203 are separate components. As compared with a configuration in which the main board 12-202 and the fan drive board 12-203 form an integral control component, the configuration in which the main board 12-202 and the fan drive board 12-203 are separate components has a small size and occupies a small space, thereby saving assembly space and facilitating assembly. Such reasonable arrangement of the main board 12-202 and the fan drive board 12-203 on the electronic control mounting member 12-218 allows the size of the electronic control box 12-10 to meet a mounting requirement of the main control board 12-202 and the fan drive board 12-203, thereby further facilitating assembly. Because the main board 12-202 is electrically connected to the fan drive board 12-203, the main board 12-202 can supply power and transmit a signal to the fan drive board 12-203.
  • Referring to FIG. 3 and FIG. 4, in some embodiments, the electronic control mounting member 12-218 has a first surface with a first groove 1-2011, and a second surface with a second groove 1-2012 opposite to the first surface to arrange the main board 12-202 and the fan drive board 12-203 on the two opposing sides of the electronic control mounting member 12-218, such that the main board 12-202 is embedded in the first groove 1-2011, and the fan drive board 12-203 is embedded in the second groove 1-2012. As such, the main board 12-202 is accommodated in the first groove 1-2011, and the fan drive board 12-203 is accommodated in the second groove 1-2012.
  • In some embodiments, the first groove 1-2011 is opposite to the second groove 1-2012, and when the main board 12-202 is embedded in the first groove 1-2011 and the fan drive board 12-203 is embedded in the second groove 1-2012, the main board 12-202 and the fan drive board 12-203 are inevitably on two opposing sides of the electronic control mounting member 12-218. The configuration in which the main board 12-202 and the fan drive board 12-203 are separate components has a small size and occupies a small space, thereby saving assembly space and facilitating assembly. The arrangement in which the first groove 1-2011 accommodates the main board 12-202 can reduce the space occupied by the main board 12-202 and the fan drive board 12-203 in the electronic control box 12-10, and the arrangement in which the second groove 1-2012 accommodates the fan drive board 12-203 can reduce the space occupied by the fan drive board 12-203 in the electronic control box 12-10.
  • In some embodiments, the electronic control mounting member 12-218 has a first surface and a second surface opposite to the first surface in the thickness direction of the electronic control mounting member 12-218 to realize a reasonable arrangement of the main board 12-202 and the fan drive board 12-203 on the electronic control mounting member 12-218.
  • In some embodiments, an area of the first groove 1-2011 matches that of the main board 12-202 to facilitate the embedding of the main board 12-202 in the first groove 1-2011 and the mounting of the main board 12-202. A position of the main board 12-202 may be limited by a wall of the first groove 1-2011, thereby ensuring the stability of the main board 12-202 embedded in the first groove 1-2011.
  • In some embodiments, an area of the second groove 1-2012 matches an area of the fan drive board 12-203 to facilitate the embedding of the fan drive board 12-203 in the second groove 1-2012 and the mounting of the fan drive board 12-203. A position of the fan drive board 12-203 may be limited by a wall of the second groove 1-2012, thereby ensuring the stability of the fan drive board 12-203 embedded in the second groove 1-2012.
  • FIG. 6 is a schematic diagram showing arrangement of an inductor in the electronic control assembly shown in FIG. 3. Referring to FIG. 3, FIG. 4, FIG. 5, and FIG. 6, in some embodiments, the electronic control assembly 12-20 may further include an inductor 12-213 electrically connected to the fan drive board 12-203 to protect the fan drive board 12-203, and the electronic control assembly 12-20 is connected in series with the fan drive board 12-203 through the inductor 12-213 to limit the short-circuit current and ensure the safety of the fan drive board 12-203.
  • Referring to FIG. 4 and FIG. 6, in some embodiments, the inductor 12-213 is connected to the electronic control mounting member 12-218 to facilitate an electrical connection between the inductor 12-213 and the fan drive board 12-203. The inductor 12-213 is supported by the electronic control mounting member 12-218, and the inductor 12-213 and the fan drive board 12-203 are located on the same side of the electronic control mounting member 12-218. As such, the inductor 12-213 can directly electrically connect to the fan drive board 12-203, thereby facilitating production and wiring.
  • Referring to FIG. 4 and FIG. 6, in some embodiments, the inductor 12-213 and the fan drive board 12-203 are located on the same side of the electronic control mounting member 12-218, thereby improving assembly efficiency and the reliability of wiring. It can be understood that the inductor 12-213 and the main board 12-202 are also on two opposing sides of the electronic control mounting member 12-218 to prevent the inductor 12-213 from occupying the mounting space of the main board 12-202, i.e., a clearance space is reserved for the main board 12-202 on the electronic control mounting member 12-218 to facilitate the mounting of the main board 12-202 and the wiring of the main board 12-202.
  • In some embodiments, one of the inductor 12-213 and the electronic control mounting member 12-218 has a first snap-fit, and the other one has a first slot in which the first snap-fit is configured to be engaged to facilitate a connection between the inductor 12-213 and the electronic control mounting member 12-218. In some embodiments, the first snap-fit may be a latch.
  • In some embodiments, the first snap-fit is engaged in the first slot to mount the inductor 12-213 on the electronic control mounting member 12-218, such that the inductor 12-213 is positioned on the electronic control mounting member 12-218. This ensures that the position of the inductor 12-213 can be determined, and facilitates the connection between the inductor 12-213 and the electronic control mounting member 12-218.
  • In some embodiments, the inductor 12-213 may has a first snap-fit, and the electronic control mounting member 12-218 may has a first slot in which the first snap-fit is configured to be engaged. In some other embodiments, the electronic control mounting member 12-218 may has the first snap-fit, the inductor 12-213 may has the first slot in which the first snap-fit is configured to be engaged. However, considering that the electronic control mounting member 12-218 serves as a carrier, the inductor 12-213 may has the first snap-fit, and the electronic control mounting member 12-218 may has the first slot in which the first snap-fit is configured to be engaged to prevent the slot in the inductor 12-213 from affecting the safety of the inductor 12-213.
  • Referring to FIG. 6, in some embodiments, the inductor 12-213 has a first connection member 1-2041 configured to connect to the electronic control mounting member 12-218 to ensure the stability of the connection between the inductor 12-213 and the electronic control mounting member 12-218. The connection between the inductor 12-213 and the electronic control mounting member 12-2182042 is realized through the connection of the first connection member 1-2041 and the electronic control mounting member 12-218. In some embodiments, the first connection member 1-2041 may be a lug.
  • In some embodiments, the first connection member 1-2041 has a first threaded hole, and the electronic control mounting member 12-218 has a second threaded hole corresponding to the first threaded hole. A locking member is connected to the second threaded hole through the first threaded hole, such that the inductor 12-213 is connected to the electronic control mounting member 12-218. In some embodiments, the locking member may be one of a bolt, a screw, or a pin.
  • In some embodiments, the inductor 12-213 may be integrally formed with the first connection member 1-2041 to ensure the stability of the connection between the inductor 12-213 and the first connection member 1-2041 and reduce the manufacturing costs.
  • In some embodiments, a position of the first snap-fit on the inductor 12-213 is staggered from a position of the first connection member 1-2041 on the inductor 12-213, such that the first snap-fit is firstly engaged in the first slot to realize positioning, and then the first connection member 1-2041 is connected to the electronic control mounting member 12-218 to facilitate the connection between the inductor 12-213 and the electronic control mounting member 12-218. As such, the mounting efficiency is improved. In some embodiments, the first snap-fit and the first connection member 1-2041 are located on two opposing sides of the inductor 12-213.
