The wall-mounted panel 100 is detachably connected to the rear shell, for example, by magnetic attraction. When the electrical control box structure 200 needs to be inspected, only the wall-mounted panel 100 needs to be removed, and then the electrical control box structure 200 can be removed from the wall-mounted panel 100. The operation is simple and does not affect the sealing performance of the front and rear shells.

[0029] In one embodiment of the present invention, the electrical control box structure 200 includes: a box body 210, which is connected to the wall panel 100; a cover plate, which covers the box body 210; and a main control board 220, which is installed inside the box body 210.

[0030] For example, such as Figure 2 and Figure 3 As shown, the enclosure 210 has a rectangular parallelepiped structure with an opening on the side opposite to the wall panel 100. A cover plate is fitted to this opening and is positioned to cover the opening. A main control board 220 is installed within the cavity formed by the enclosure 210 and the cover plate.

[0031] In one embodiment of this utility model, the electrical control box structure 200 further includes: a hanging hole 310, which is disposed on one of the wall-mounting plate 100 and the box body 210; a hook 320, which is disposed on the other of the wall-mounting plate 100 and the box body 210, and the hook 320 can be hooked onto the hanging hole 310; a connecting plate 330, which is disposed on the box body 210; and a box body fastener 340, which is connected between the connecting plate 330 and the wall-mounting plate 100.

[0032] For example, such as Figures 1 to 3 As shown, the wall panel 100 has square hanging holes 310. A square hook 320 is provided on the side of the housing 210 near the wall panel 100. The square hook 320 corresponds to the square hanging hole 310. The housing 210 can be hooked onto the square hanging hole 310 of the wall panel 100 via the square hook 320. To improve the reliability of the connection between the housing 210 and the wall panel 100, a connecting plate 330 can be provided on the housing 210, and a fastener 340 can be inserted between the connecting plate 330 and the wall panel 100. For example, the fastener 340 includes, but is not limited to, fastening screws. Furthermore, multiple sets of hanging holes 310 and hooks 320 can be provided between the housing 210 and the wall panel 100.

[0033] In one embodiment of the present invention, the electrical control box structure 200 further includes a motherboard fixing buckle 400, which is connected to the side wall of the box body 210 and is used to fasten the main control board 220.

[0034] For example, such as Figure 3 As shown, multiple fixing clips can be spaced apart on each side wall of the housing 210, and these clips can deform to a certain extent. During installation, simply press down on the main control board 220 to move it past the fixing clips and fix it to the inside of the clips. During disassembly, simply pull on the main control board 220 to separate it from the fixing clips.

[0035] In one embodiment of the present invention, the electrical control box structure 200 further includes a main board fastener, which is connected between the cover plate, the main control board 220 and the box body 210.

[0036] To improve the connection strength of the main control board 220, a motherboard fastener can be connected between the main control board 220 and the enclosure 210. For example, the motherboard fastener includes, but is not limited to, screws. To reduce costs, the motherboard fastener can be threaded through the cover plate, the main control board 220, and the enclosure 210, thus eliminating the need for separate fasteners to connect the cover plate and the enclosure 210.

[0037] In one embodiment of the present invention, the electrical control box structure 200 further includes: a mounting groove 500, which is disposed at the corner of the box body 210; and a three-in-one sensor 600, which is installed in the mounting groove 500.

[0038] For example, such as Figure 2 and Figure 3 As shown, a partition is installed at the lower left corner inside the housing 210. The partition and the side wall of the housing 210 together form a mounting groove 500 that is compatible with the three-in-one sensor 600. The three-in-one sensor 600 is fixedly installed in the mounting groove 500.

[0039] In one embodiment of the present invention, the electrical control box structure 200 further includes: a low-voltage wiring trough 710, which is disposed on the box body 210 and communicates with the inner cavity of the box body 210; and a low-voltage cable fastener 720, which is disposed upstream of the low-voltage wiring trough 710.

[0040] Furthermore, in one embodiment of this utility model, the electrical control box structure 200 further includes: a high-voltage wiring trough 810, which is disposed on the box body 210 and communicates with the inner cavity of the box body 210; and a high-voltage wire fastener 820, which is disposed inside the high-voltage wiring trough 810.

[0041] Specifically, such as Figure 2 and Figure 3 As shown, low-voltage wiring channels 710 and high-voltage wiring channels 810 are arranged sequentially from left to right on the upper side of the rectangular enclosure 210. A low-voltage cable retainer 720 is installed on the left side of the low-voltage wiring channel 710. Low-voltage wires are first secured by the low-voltage cable retainer 720 before passing through the low-voltage cable retainer 720 and entering the enclosure 210. The low-voltage cable retainer 720 has a water trap to prevent water accumulation. A high-voltage cable retainer 820 is installed inside the high-voltage wiring channel 810. High-voltage wires enter the enclosure 210 from outside the enclosure 210 after being secured and guided by the high-voltage wiring channel 810 and its internal high-voltage retainer. This limits the distance between high-voltage and low-voltage wires, preventing high-voltage interference with low-voltage wires.

[0042] In one embodiment of this utility model, the electrical control box structure 200 further includes an emergency button 900, which is disposed on the box body 210 and used for powering on, powering off, or resetting the alarm.

[0043] like Figure 2 and Figure 3 As shown, the emergency button 900 can be located on the bottom surface of the enclosure 210. The emergency button can be used to power on, power off, or reset the alarm. For example, a short press can be set to power on or off, and a long press to reset the alarm.

[0044] A second aspect of this utility model provides a fresh air unit, including the electrical control box assembly for the fresh air indoor unit as described above.

[0045] In addition, the fresh air unit also includes a front casing and a rear casing. The front casing and the rear casing are connected end-to-end. A magnetic connector is provided between the wall-mounted panel 100 and the rear casing. The magnetic connector can attract the wall-mounted panel 100 to the rear casing. The electrical control box structure 200 is detachably connected to the inside of the wall-mounted panel 100, that is, the electrical control box structure 200 is located between the rear casing and the wall-mounted panel 100. When the electrical control box structure 200 needs to be inspected, the wall-mounted panel 100 is forcefully separated from the rear casing, and then the electrical control box structure 200 is separated from the wall-mounted panel 100.

[0046] Furthermore, the fresh air unit provided by this utility model includes the electrical control box assembly for the fresh air indoor unit as described above, and therefore also possesses the advantages described above.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
