[0001] The utility model relates to air conditioner technical field, specifically, relate to a kind of electric control box and air conditioner. BACKGROUND

[0002] In the wall-mounted air conditioner indoor unit, it needs to be hung on the wall in the room, so the internal space of the wall-mounted air conditioner indoor unit is relatively tight. The side edge of the circuit board in the electric control box is provided with a plurality of plug-in terminals. Considering the circuit layout, the plug-in terminals need to be set on one side in the horizontal direction, such as the left side or the right side. By setting such plug-in terminals, the wiring needs to occupy a large horizontal space after being plugged into the plug-in terminals. The electric control box cover is easy to interfere with the wiring, or the electric control box cover causes the wiring to bend to a large extent, so that the wiring bears a large pressure, which easily leads to loose connection of the wiring or reduces the service life of the wiring. SUMMARY

[0003] The first aspect of the utility model aims to provide an electric control box to solve the technical problem of excessive bending of the lead in the existing electric control box.

[0004] The electric control box provided in the first aspect of the utility model includes an electric control box body and a circuit board installed in the electric control box body. The circuit board is provided with plug-in terminals. The electric control box body is provided with a first side wall and a second side wall adjacent to each other. The first side wall is provided with an outward protruding part, and the second side wall is provided with a lead outlet. The outward protruding part is arranged corresponding to the plug-in terminals, and the protruding space formed by the outward protruding part is connected to the lead outlet.

[0005] The electric control box of the utility model has the following beneficial effects:

[0006] By setting the outward protruding part corresponding to the plug-in terminals on the first side wall of the electric control box body and connecting it with the lead outlet arranged on the second side wall, the local part of the lead inserted into the plug-in terminals can be accommodated. This can reduce the bending degree of the lead between the position of the plug-in terminals and the position of the lead outlet, thereby reducing the possibility of loose connection of the lead and improving the service life of the lead.

[0007] In an optional technical solution, the electric control box body includes an electric control box seat and an electric control box cover. The circuit board is installed in the electric control box seat, and the electric control box cover is covered on the electric control box seat from the left side or the right side of the electric control box seat. The outward protruding part is arranged on the electric control box cover, and the lead outlet is arranged on the electric control box seat.

[0008] The electric control box body is divided into an electric control box base and an electric control box cover, and the electric control box base and the electric control box cover are arranged along the left-right direction, so that the front and rear surfaces of the electric control box base and the electric control box cover are respectively provided with structures protruding or recessing along the left-right direction, thereby facilitating the layout of various mounting structures and sealing structures on the electric control box body.

[0009] In an optional technical solution, the outward protruding part comprises a longitudinal outward protruding part and a transverse outward protruding part, the extension direction of the longitudinal outward protruding part is parallel to the arrangement direction of the plurality of plug-in terminals on the circuit board, the transverse outward protruding part is in communication with the longitudinal outward protruding part, and the rear end of the transverse outward protruding part further protrudes from the partial rear wall of the electric control box base.

[0010] By arranging the longitudinal outward protruding part and making the extension direction thereof parallel to the arrangement direction of the plurality of plug-in terminals, sufficient space is provided for the lead wires of the plurality of plug-in terminals to bend and lead to the lead wire outlet. By arranging the transverse outward protruding part, the lead wires of the plurality of plug-in terminals can be gathered and guided to the lead wire outlet in the transverse outward protruding part. By making the rear end of the transverse outward protruding part protrude from the partial rear part of the electric control box, the lead wires can be further bent by the guidance of the transverse outward protruding part, so as to keep the same direction as the plug-in terminals and be led out of the lead wire outlet.

[0011] In an optional technical solution, the electric control box base is provided with a rear protruding part and a rear lower side wall, the bottom of the rear protruding part is provided with the lead wire outlet, the rear lower side wall is connected with the rear protruding part, and the upper edge of the rear lower side wall is higher than the lead wire outlet.

[0012] By making the upper edge of the rear lower side wall higher than the lead wire outlet at the bottom of the rear protruding part, the height of the lead wire when passing the upper edge of the rear lower side wall is higher than the height when passing the lead wire outlet. Therefore, when a fire occurs in the electric control box and spreads along the lead wire, the speed of the fire spreading along the lead wire can be significantly reduced or even stopped, and the fireproof performance of the wall-mounted air conditioner indoor unit is improved.

[0013] In an optional technical solution, the height of the upper edge of the inclined angle part gradually decreases in the direction towards the electric control box cover.

[0014] By arranging the inclined angle part on the upper edge of the rear lower side wall, the lead wire can be guided by the inclined angle part during the process of being placed into the lead wire outlet. After the lead wire slides through the inclined angle part on the upper edge of the rear lower side wall, the lead wire falls into the range of the lead wire outlet, and the installation efficiency is improved.

[0015] In an optional technical solution, the front wall of the electric control box cover is provided with a horizontal extension part extending in a closing direction, the closing direction being the direction in which the electric control box cover is closed on the electric control box seat; the circuit board is fixedly provided with a display assembly, and a plug-in structure is arranged between the display assembly and the electric control box seat, the plug-in structure comprising a plug-in groove and a plug-in rib, one of the plug-in groove and the plug-in rib being arranged on the electric control box seat, and the other being arranged on the display assembly; and the plug-in rib is inserted into the plug-in groove in the closing direction.

[0016] Generally, during assembly, the display assembly is first mounted on the circuit board, then the circuit board is mounted on the electric control box seat, and then the electric control box cover is closed on the electric control box seat. By arranging the horizontal extension part on the front wall of the electric control box cover in the closing direction, the size of the front wall of the electric control box seat in the closing direction can be reduced, and thus the size of at least one of the plug-in groove and the plug-in rib can be reduced, so that the circuit board does not need to be aligned with the plug-in groove and the plug-in rib at the beginning of the mounting process, thereby reducing the difficulty of installation.

[0017] In an optional technical solution, the front surface and the upper surface of the electric control box seat are provided with a limiting rib, and the edge of the electric control box seat facing the electric control box cover is arranged in a spaced manner with the limiting rib.

[0018] By arranging the limiting rib, the maximum distance of the electric control box cover being closed on the electric control box seat can be limited, so as to avoid the electric control box cover pressing the display assembly. Meanwhile, the front surface of the limiting rib can also abut against the face shell, so that when the face shell is stepped on or pressed, the rear side of the face shell is in contact with the front surface of the limiting rib, thereby transferring part of the load to the electric control box seat, reducing the load transmitted to the circuit board through the display assembly, reducing the load bearing of the circuit board, and thus prolonging the service life of the circuit board.

[0019] In an optional technical solution, the electric control box cover is provided with a front protruding part, the front protruding part being located in the region of the front wall of the electric control box cover facing the electric control box seat, and the region between the limiting rib and the edge of the electric control box seat facing the electric control box cover being shielded by the front protruding part.

[0020] By arranging the front protruding part to shield the above-mentioned region of the front wall of the electric control box seat, a multi-layer structure can be formed at the junction of the electric control box seat and the electric control box cover, thereby improving the sealing performance at the junction of the two, so as to reduce the speed of water vapor and dust in the air entering the inside of the electric control box body.

[0021] In an optional technical solution, the front protruding part is further provided with a first front protruding rib protruding from the front protruding part, the front surface of the electric control box cover is further provided with a second front protruding rib, and the first front protruding rib intersects with the second front protruding rib.

[0022] By setting the intersecting first front convex ridge and the second front convex ridge, a larger area of the face shell can be supported by the first front convex ridge and the second front convex ridge, on the one hand, the support burden of the face shell when being stepped on is shared, the stress of the display assembly and the circuit board is reduced, and the possibility of damage of the circuit board is reduced, on the other hand, the stress concentration degree of the face shell when being stepped on is weakened, and therefore the possibility of white top phenomenon is reduced.

[0023] The second aspect of the utility model discloses a kind of air conditioners, to solve the technical problem of the degree of bending of lead in electric control box.

[0050] The electric control box body is divided into the electric control box seat 100 and the electric control box cover 200, and the electric control box seat 100 and the electric control box cover 200 are arranged along the left-right direction, so that the structure protruding or recessing along the left-right direction can be arranged on the front and rear surfaces of the electric control box seat 100 and the electric control box cover 200, thereby facilitating the layout of various mounting structures and sealing structures on the electric control box body.

[0051] In the embodiment, the electric control box cover 200 is covered on the electric control box seat 100 from the right side of the electric control box seat 100, so the covering direction is from right to left, and the outer protruding part 210 is also arranged on the right wall of the electric control box cover 200 and protrudes rightward. Of course, in another implementation, the electric control box cover 200 can also be covered on the electric control box seat 200 from the left side of the electric control box seat 100, so in this implementation, the covering direction is from left to right.

[0052] Figure 6 A right view of the electric control box provided in the embodiment one of the utility model, wherein the electric control box cover is omitted; as Figures 1-6As shown, the outer protrusion 210 includes a longitudinal outer protrusion 211 and a transverse outer protrusion 212, the extending direction of the longitudinal outer protrusion 211 is parallel to the arrangement direction of the plurality of plug-in terminals 410 on the circuit board 420, the transverse outer protrusion 212 is communicated with the longitudinal outer protrusion 211, and the rear end of the transverse outer protrusion 212 also protrudes from the partial rear wall of the electric control box seat 100.

[0053] By setting the longitudinal outer protrusion 211 and the extending direction being parallel to the arrangement direction of the plurality of plug-in terminals 410, sufficient space is provided for the lead wires 440 of the plurality of plug-in terminals 410 to bend and lead to the lead wire outlet 110. By setting the transverse outer protrusion 212, the lead wires 440 of the plurality of plug-in terminals 410 can be converged and guided to the lead wire outlet 110 in the transverse outer protrusion 212. By setting the rear end of the transverse outer protrusion 212 to protrude from the partial rear of the electric control box, the lead wires 440 can continue to bend and keep the direction of insertion into the plug-in terminals by the guidance of the transverse outer protrusion 212, and then lead out from the lead wire outlet 110.

[0054] Specifically, in the embodiment, the circuit board 420 is provided with a first plug-in terminal 411, a second plug-in terminal 412 and a plurality of third plug-in terminals 413, which are arranged from top to bottom on the right edge of the circuit board 420, wherein the first plug-in terminal 411 is connected with the cross-flow fan motor through the cross-flow fan motor wire 441; the second plug-in terminal 412 is connected with the temperature sensing bag through the temperature sensing bag wire 442; and the third plug-in terminal 413 is connected with the stepping motor through the stepping motor wire 443.

[0055] Figure 7 A perspective view of the electric control box without the electric control box cover provided in the embodiment one of the utility model is shown; Figure 8 A perspective view of the electric control box without the electric control box cover provided in the embodiment one of the utility model is shown from another direction; Figure 1 And Figures 6-8 As shown, the electric control box seat 100 is provided with a rear protruding portion 120 and a rear lower side wall 130, the bottom of the rear protruding portion 120 is provided with the lead wire outlet 110, the rear lower side wall 130 is connected with the rear protruding portion 120, and the upper edge of the rear lower side wall 130 is higher than the lead wire outlet 110.

[0056] By making the upper edge of the rear lower sidewall 130 higher than the lead outlet 110 at the bottom of the rear protrusion 120, the lead 440 is higher than the height passing through the lead outlet 110 when passing around the upper edge of the rear lower sidewall 130, so that if a fire occurs in the electric control box, the spread of the fire along the lead 440 can be significantly reduced or even stopped, thereby improving the fireproof performance of the wall-mounted air conditioner indoor unit.

[0057] Specifically, the lead outlet 110 can include a through hole, and the rear protrusion 120 of the electric control box seat 100 is connected to the edge of the electric control box cover 200 through a gap part. By providing the gap part, the lead 440 can be placed in the through hole in the horizontal direction without passing through the through hole from one side to the other side. In other words, in this embodiment, the side of the lead outlet 110 facing the electric control box cover 200 is provided with a protruding part 111, which can function as a hook to limit the lead 440 within the range of the through hole.

[0058] As shown in Figure 1 and Figures 6-8 , optionally, the upper edge of the rear lower sidewall 130 is provided with an inclined angle part 131, and the height of the upper edge of the inclined angle part 131 gradually decreases in the direction towards the electric control box cover 200.

[0059] By providing such an inclined angle part 131 on the upper edge of the rear lower sidewall 130, the lead 440 can be guided by the inclined angle part 131 during the process of placing the lead 440 into the lead outlet 110, and after the lead 440 slides over the inclined angle part 131 on the upper edge of the rear lower sidewall 130, the lead 440 falls into the range of the lead outlet 110, thereby improving the installation efficiency.

[0060] Specifically, in this embodiment, the inclined angle part 131 is located on the right half of the upper edge of the rear lower sidewall 130, that is, the corner part between the upper edge of the rear lower sidewall 130 and the edge facing the electric control box cover 200, and the upper edge of the inclined angle part 131 is inclined downward to the right. That is, the right half of the upper edge of the rear lower sidewall 130 presents a lower height to the right. However, even if the right half of the upper edge of the rear lower sidewall 130 presents the above appearance, the inclined angle part 131 is still higher than the upper edge of the through hole part of the lead outlet 110.

[0061] Figure 9 A perspective view of the electric control box from another direction according to Embodiment One of the present application is shown in Figure 1 , Figure 3 and Figure 9As shown, the front wall of the electric control box cover 200 is provided with a horizontal extension 220 extending in the closing direction, which is the direction in which the electric control box cover 200 is closed on the electric control box seat 100. The circuit board 420 is fixedly installed with a display assembly 430, and the display assembly 430 and the electric control box seat 100 are provided with a plug-in structure, which includes a plug-in groove 431 and a plug-in rib 140, one of which is arranged on the electric control box seat 100 and the other of which is arranged on the display assembly 430. The plug-in rib 140 is inserted into the plug-in groove 431 in the closing direction.

[0062] Generally, during assembly, the display assembly 430 is first installed on the circuit board 420, then the circuit board 420 is installed on the electric control box seat 100, and then the electric control box cover 200 is closed on the electric control box seat 100. By providing the horizontal extension 220 on the front wall of the electric control box cover 200 in the closing direction, the size of the front wall of the electric control box seat 100 in the closing direction can be reduced, and thus the size of at least one of the plug-in groove 431 and the plug-in rib 140 can be reduced. Therefore, the circuit board 420 does not need to be aligned with the plug-in groove 431 and the plug-in rib 140 at the beginning of the installation process, thereby reducing the difficulty of installation.

[0063] Specifically, the top wall of the electric control box seat 100 is provided with an upper positioning groove 161, and the upper edge of the circuit board 420 is inserted into the upper positioning groove 161, thereby defining the position of the upper part of the circuit board 420. The bottom wall of the electric control box seat 100 is provided with a lower positioning groove 162, and the lower edge of the circuit board 420 is inserted into the lower positioning groove 162, thereby defining the position of the lower part of the circuit board 420. During the installation of the circuit board 420, the upper edge and the lower edge of the circuit board 420 are first inserted into the upper positioning groove 161 and the lower positioning groove 162, respectively. By shortening at least one of the plug-in rib 140 and the plug-in groove 431, the upper and lower edges of the circuit board 420 only need to be inserted at the beginning of the installation process of the circuit board 420, without the need to align the plug-in rib 140 and the plug-in groove 431 at the same time, thereby reducing the number of alignments required at the beginning of the installation process of the circuit board 420, improving the installation efficiency, and reducing the difficulty of installation. At the moment when the plug-in rib 140 and the plug-in groove 431 need to be aligned, the upper edge and the lower edge of the circuit board 420 have already slid a certain distance in the upper positioning groove 161 and the lower positioning groove 162, and the position of the circuit board 420 has actually been defined. Therefore, the plug-in rib 140 and the plug-in groove 431 can be smoothly aligned.

[0064] Specifically, the plug-in convex ridge 140 in the embodiment can be arranged on the front wall of the electric control box seat 100, and the plug-in groove 431 is a groove arranged on the rear surface of the display assembly 430, and the plug-in groove 431 is a groove with notches at the left and right ends. The extension directions of the plug-in groove 431 and the plug-in convex ridge 140 are both left and right directions.

[0065] Of course, the horizontal extension part 220 is arranged not only to reduce the length of at least one of the plug-in convex ridge 140 and the plug-in groove 431, but also to block the area of the front surface of the electric control box, and to increase the distance between the display assembly 430 and the left end or the right end of the wall-mounted air conditioner indoor unit where the electric control box is arranged, so that the wall-mounted air conditioner indoor unit is more beautiful.

[0066] As shown in Figure 1 , Figure 3 , Figure 8 and Figure 9 , optionally, the front surface and the upper surface of the electric control box seat 100 are provided with a limiting convex ridge 150, and the edge of the electric control box seat 100 facing the electric control box cover 200 is arranged in a spaced manner with the limiting convex ridge 150.

[0067] By arranging the limiting convex ridge 150, the maximum distance of the electric control box cover 200 covering the electric control box seat 100 can be limited, so as to avoid the electric control box cover 200 pressing the display assembly 430. At the same time, the front surface of the limiting convex ridge 150 can also abut the face shell, so that when the face shell is stepped on or pressed, the rear side of the face shell is in contact with the front surface of the limiting convex ridge 150, thereby transferring part of the load to the electric control box seat 100, reducing the load transmitted to the circuit board 420 through the display assembly 430, reducing the load bearing of the circuit board 420, thereby improving the service life of the circuit board 420.

[0068] In the embodiment, the right edge of the electric control box seat 100 is the edge of the electric control box seat 100 facing the electric control box cover 200, and the limiting convex ridge 150 can be arranged at equal intervals with the right edge of the electric control box seat 100. The limiting convex ridge 150 protrudes forward from the front wall of the electric control box seat 100.

[0069] As shown in Figure 1 , Figure 3 , Figure 8 and Figure 9 , optionally, the electric control box cover 200 is provided with a front protruding part 230, the front protruding part 230 is located in the region of the front wall of the electric control box cover 200 facing the electric control box seat 100, and the region between the limiting convex ridge 150 and the edge of the electric control box seat 100 facing the electric control box cover 200 is blocked by the front protruding part 230.

[0070] By setting the front protruding portion 230 to shield the above-mentioned area of the front wall of the electric control box seat 100, a multi-layer structure can be formed at the junction of the electric control box seat 100 and the electric control box cover 200, thereby improving the sealing performance at the junction of the two to reduce the speed of water vapor and dust in the air entering the inside of the electric control box body.

[0071] In addition, the setting of the front protruding portion 230 can also make this part of the front wall of the electric control box cover 200 more forward, and if the thickness and size of the front protruding portion 230 are reasonably set, at least part of the front protruding portion 230 can be flush with the front surface of the limiting protruding rib 150 to jointly bear the force transmitted to the electric control box body by the face shell, thereby increasing the force bearing area and preventing the face shell from being stepped on or pressed and then causing the white top phenomenon due to local pressure concentration.

[0072] As shown in Figure 1 , Figure 3 and Figure 9 , optionally, the front protruding portion 230 is further provided with a first front protruding rib 241 protruding from the front protruding portion 230, and the front surface of the electric control box cover 200 is further provided with a second front protruding rib 242, and the first front protruding rib 241 intersects with the second front protruding rib 242.

[0073] By setting the intersecting first front protruding rib 241 and second front protruding rib 242, a larger area of the face shell can be supported by the first front protruding rib 241 and the second front protruding rib 242, which on the one hand shares the support burden of the face shell when stepped on, reduces the stress of the display assembly 430 and the circuit board 420, and reduces the possibility of damage to the circuit board 420, and on the other hand also weakens the stress concentration degree of the face shell when stepped on, thereby reducing the possibility of the white top phenomenon.

[0074] Specifically, the first front protruding rib 241 extends in the vertical direction, while the second front protruding rib 242 extends in the horizontal direction, and one first front protruding rib 241 and two parallel second front protruding ribs 242 intersect to form a shape of a π letter rotated counterclockwise by 90°. In the height direction, the first front protruding rib 241 is approximately equivalent to the display assembly 430 to share the stress of the display assembly 430 when the face shell is stepped on.
