[0041] The present application provides an electric control box, an air conditioner indoor unit and a heating and ventilation device.

[0042] It should be noted that HVAC equipment includes but is not limited to air conditioners, multi-split units, heat pumps, water heaters, swimming pool machines and other equipment. Taking HVAC equipment with refrigerant as the heating medium and water as the heating object as an example, the HVAC equipment may include an air conditioner indoor unit installed indoors for heating water and an air conditioner outdoor unit that may be installed outdoors and perform heat exchange with the external environment. The air conditioner indoor unit may include a water circulation flow path and a refrigerant pipe, in which refrigerant flows. The refrigerant is preferably a new type of flammable refrigerant such as R32 and R290, which has the advantages of high thermal conductivity, large latent heat of evaporation, good fluidity, and low delivery pressure. The air conditioner indoor unit heats the water by exchanging heat between the refrigerant in the refrigerant pipe and the water in the water circulation flow path to output water at a set temperature.

[0043] See also Figures 1 to 7 The electric control box 100 of one embodiment of the present application can be applied to an air conditioner indoor unit 1000, which includes a main board bracket 2, a main control board 3, a circuit component 4 and a separation bracket 5.

[0044] Specifically, the mainboard bracket 2 has an installation space 20, the main control board 3 is fixedly arranged in the installation space 20, the main control board 3 is such as a circuit board, the circuit component 4 is fixedly arranged on the main control board 3, and the circuit component 4 is such as an integrated circuit chip, an electronic component, etc. In the first direction Z, the circuit component 4 has a height, and different circuit components 4 can have different heights. The separation bracket 5 is mounted on the mainboard bracket 2, and in the first direction Z, the separation bracket 5 and the circuit component 4 have a height difference and are arranged at a certain distance from each other, so that the separation bracket 5 can avoid each circuit component 4. The separation bracket 5 includes at least one first card line body 51 and at least one second card line body 52, the first card line body 51 can limit the routing direction of the strong wire 6, the strong wire 6 can connect the main control board 3 and the strong current component 300, the second card line body 52 can limit the routing direction of the weak wire 7, the weak wire 7 can connect the main control board 3 and the weak current component 400, and the first card line body 51 and the second card line body 52 are arranged separately from each other.

[0045] The separation bracket 5 is mounted on the mainboard bracket 2. The separation bracket 5 and the mainboard bracket 2 can be integrally formed. The separation bracket 5 and the mainboard bracket 2 can also be independently set and fixedly connected. They can be detachably fixedly connected by means of threaded connection, bundling connection or snap connection, or can be non-detachably fixedly connected by means of bonding or welding. The first direction Z can be the direction of gravity. The separation bracket 5 can be horizontally set or inclined at an angle to the horizontal plane. The separation bracket 5 can be located above the mainboard bracket 2, the main control board 3 and the circuit component 4. The separation bracket 5 can also be located below the mainboard bracket 2, the main control board 3 and the circuit component 4. The first direction Z can also be the horizontal direction. The separation bracket 5 can be vertically set or inclined at an angle to the direction of gravity. The separation bracket 5 can be located on the left or right side of the mainboard bracket 2.

[0046] There may be only one first wire clamping body 51, which forms a wire clamping groove with a certain length. The extension direction of the wire clamping groove is the routing direction of the strong wire 6, and the strong wire 6 can be embedded in the wire clamping groove. There may also be multiple first wire clamping bodies 51 arranged at intervals, and all first wire clamping bodies 51 jointly define the routing direction of the strong wire 6. There may be only one second wire clamping body 52, which forms a wire clamping groove with a certain length. The extension direction of the wire clamping groove is the routing direction of the weak wire 7, and the weak wire 7 can be embedded in the wire clamping groove. There may also be multiple second wire clamping bodies 52 arranged at intervals, and all second wire clamping bodies 52 jointly define the routing direction of the weak wire 7. The first wire clamping body 51 and the second wire clamping body 52 are arranged to be separated from each other, so that the routing direction of the strong wire 6 and the routing direction of the weak wire 7 will not intersect with each other, thereby avoiding cross contact between the strong wire 6 and the weak wire 7.

[0047] In the illustrated embodiment, by setting up a separation bracket 5 on the mainboard bracket 2, the separation bracket 5 is spaced apart from the circuit component 4 so as to avoid the circuit component 4; by setting a first card line body 51 and a second card line body 52 separated from each other, separate wiring of the strong wire 6 and the weak wire 7 is achieved.

[0048] See also Figures 4 to 11 In some embodiments, the separation bracket 5 and the mainboard bracket 2 are butted and fixed in the first direction Z. The side of the separation bracket 5 facing the mainboard bracket 2 is provided with at least one first fastener 53 arranged along the first direction Z, and the side of the mainboard bracket 2 facing the separation bracket 5 is provided with at least one second fastener 21 arranged along the first direction Z, and the first fastener 53 and the second fastener 21 correspond to each other. During assembly, the separation bracket 5 is placed above the mainboard bracket 2 and aligned with the mainboard bracket 2, and then the separation bracket 5 is pressed downward along the first direction Z, so that the first fastener 53 is fastened and fixed with the corresponding second fastener 21, so as to realize the fixed connection between the separation bracket 5 and the mainboard bracket 2.

[0049] In the illustrated embodiment, the separation bracket 5 may include a separation bracket body 50, and two first side edges 57 of the separation bracket body 50 that are relatively arranged in the second direction Y both extend downwardly in a cantilevered manner to form a plate-shaped first clip 53, and the free end of the first clip 53 has a clip protrusion 531. The second direction Y may be perpendicular to the first direction Z. The mainboard bracket 2 is located below the separation bracket 5, and includes a mainboard bracket body 22, and two second side edges 23 of the mainboard bracket body 22 that are relatively arranged in the second direction Y both extend upwardly in a cantilevered manner to form a plate-shaped second clip 21, and the free end of the second clip 21 has a through-going clip groove 211. During assembly, the clip protrusion 531 passes through the corresponding clip groove 211 and then clips the groove edge of the clip groove 211, so as to realize the clip fixation of the separation bracket 5 and the mainboard bracket 2.

[0050] Since the separation bracket 5 and the mainboard bracket 2 are docked in the first direction Z, and the first clamp 53 and the second clamp 21 are arranged in the first direction Z, the docking and fixation of the two can be achieved simultaneously by applying force to the separation bracket 5 in the first direction Z, thereby simplifying the assembly process of the separation bracket 5 and the mainboard bracket 2.

[0051] See also Figure 6 , Fig.10 and Fig.11In some embodiments, the first wire clamping body 51 includes a first elastic arm 511 extending in a cantilever shape, and the first elastic arm 511 can be elastically pressed on the strong wire 6. The second wire clamping body 52 includes two second elastic arms 521 extending in a cantilever shape, and the two second elastic arms 521 are arranged opposite to each other, and a wire clamping opening 522 that can elastically clamp the weak wire 7 is formed between the free ends of the two second elastic arms 521. When routing, the strong wire 6 is arranged under the first elastic arm 511 and is pressed and fixed by the first elastic arm 511; the weak wire 7 squeezes into the space between the two second elastic arms 521 from the wire clamping opening 522 or is directly passed through the space between the two second elastic arms 521.

[0052] The first elastic arm 511 extends upward in a cantilevered manner along the first direction Z from the upper surface of the separation bracket body 50. The free end of the first elastic arm 511 has an arch 512 formed by bending toward the upper surface of the separation bracket body 20. The distance between the arch 512 and the upper surface of the separation bracket body 50 can be slightly smaller than the diameter of the strong wire 6, so that the arch 512 can elastically press the strong wire 6. The second elastic arm 521 extends upward in a cantilevered manner along the first direction Z from the upper surface of the separation bracket body 50. A wire clamping opening 522 is formed between the free ends of the two second elastic arms 521. In normal state, the wire clamping opening 522 can be closed, that is, the free ends of the two second elastic arms 521 are close together; or, there is a certain distance between the free ends of the two second elastic arms 521. During assembly, the weak wire 7 can be squeezed into the wire clamping opening 522 to make the two second elastic arms 521 open relatively outward until the weak wire 7 enters between the two second elastic arms 521. The width of the wire-holding opening 522 may be smaller than the diameter of the weak wire 7 , thereby preventing the weak wire 7 from being separated from the second wire-holding body 52 .

[0053] In this embodiment, the first clamping wire body 51 with a single elastic arm is provided to restrict the strong wire 6, and the second clamping wire body 52 with double elastic arms is provided to restrict the weak wire 7. In some alternative structures, the first clamping wire body 51 can also be a single elastic arm structure, and the second clamping wire body 52 can be a double elastic arm structure.

[0055] In the illustrated embodiment, the first plate 54 and the second plate 55 can be arranged horizontally, and the connecting plate 56 can be perpendicular to the first plate 54 and the second plate 55. The first plate 54 can be provided with a plurality of first card line bodies 51, and the strong wire 6 is connected to the main control board 3 after passing through each first card line body 51.
