[0002] In the wall-mounted air conditioner indoor unit, the air conditioner electric control box is usually arranged at the end of the internal space of the wall-mounted air conditioner indoor unit, such as the left end or the right end. However, with such an arrangement, the overall length of the wall-mounted air conditioner indoor unit is increased, which on the one hand leads to an increase in the use of materials for the base, the middle frame and the panel of the air conditioner, thereby increasing the cost of the air conditioner, and on the other hand, also leads to a large length of the air conditioner, which is not easy to install in the indoor space.

[0003] Generally, a display area is arranged on the panel of the wall-mounted air conditioner indoor unit, and a display assembly is arranged behind the display area to display information such as the set temperature and the operating mode of the air conditioner. The display assembly is mounted on the inner surface of the panel and faces the display area. Usually, the display assembly is arranged in a separate display box, but the display box is arranged on the front surface of the wall-mounted air conditioner indoor unit, which may interfere with the arrangement of the air conditioner electric control box on the front of the wall-mounted air conditioner indoor unit. SUMMARY

[0004] The first aspect of the utility model aims to provide an air conditioner electric control box to solve the technical problem of interference of the existing display box body with the electric control box body.

[0006] The air conditioner electric control box provided by the utility model has the following beneficial effects:

[0007] By arranging the display assembly on the circuit board, the display assembly can be integrated in the air conditioner electric control box to control the display lamp to display information, without the need to separately arrange a box body for the display driving circuit, and without the need to separately connect the display assembly and the air conditioner electric control box, thereby shortening the assembly time. Moreover, by arranging the main body part of the first pin element, which has a height three times higher than the height of the lamp bead part of the display lamp, on the back surface of the circuit board, the spacing between the front surface of the circuit board and the front wall of the air conditioner electric control box can be reduced, which is conducive to the contact between the display assembly and the front panel of the air conditioner and the clear display of relevant information.

[0008] In an optional technical solution, the display component comprises a display driving circuit electrically connected to the display lamp, and the display driving circuit is located on the back of the circuit board and opposite to the display lamp.

[0009] By arranging the display driving circuit on the back of the circuit board and opposite to the display lamp, the area of the circuit board occupied by the display driving circuit and the display lamp can be significantly reduced, thereby facilitating control of the overall area of the circuit board in the air conditioner control box, and arranging the display driving circuit opposite to the display lamp can shorten the wiring distance between the display lamp and the display driving circuit, reduce the conductor length between the display lamp and the display driving circuit, and facilitate cost reduction of the air conditioner control box.

[0010] In an optional technical solution, the display lamp is an LED lamp or a lamp bead.

[0011] The LED lamp or the lamp bead is used as the display lamp, which can emit light with large luminous flux in a small space to ensure that the pattern displayed through the lampshade is clear on the front panel of the air conditioner.

[0012] In an optional technical solution, the display component is located at the lower part of the circuit board.

[0013] Since the air conditioner control box is applied to the air conditioner indoor unit and located in front of the fan motor, the motor gland, and the refrigerant pipe of the indoor heat exchanger, the lower space of the air conditioner control box is relatively cramped. Such an arrangement means that the display driving circuit is also located at the lower part of the air conditioner control box, and the electronic elements of the display driving circuit are relatively thin. Arranging the display component at the lower part of the circuit board facilitates full use of the lower space in the air conditioner control box. In addition, such an arrangement can also reduce the position of the display component relative to the air conditioner control box, and further reduce the position of the display component relative to the air conditioner indoor unit. When a user needs to observe the information of the display component, he or she does not need to tilt his or her head at a large angle, thereby improving the user experience.

[0014] In an optional technical solution, the display component comprises a lampshade configured to be attached to the front panel of the air conditioner indoor unit, and the lampshade is provided with light transmission holes, and each display lamp is arranged opposite to a light transmission hole.

[0015] By arranging the light transmission holes of the lampshade opposite to the display lamps, the brightness of each light transmission hole can be controlled by each display lamp, and by attaching the lampshade and the circuit board to the front panel, the lampshade can be attached to the inner side of the front panel to clearly present the pattern of the light transmission holes on the front panel.

[0016] In an optional technical solution, the box body comprises a box base and a box cover, the circuit board is mounted on the box base, the box base is provided with a first notch part and a second notch part, the first notch part is used for accommodating the lampshade to pass through, and the lampshade is configured to protrude from the box base; the second notch part is connected with the first notch part and the edge of the box base facing the box cover, and the box cover is provided with an extending part which shields the second notch part.

[0017] By arranging the first notch part to accommodate the lampshade to pass through, the lampshade can protrude from the box base, so that in the air conditioner electric control box, the lampshade can be attached to the front panel of the air conditioner indoor unit before the front wall of the air conditioner electric control box, so as to more clearly display information, on the other hand, part of the thickness of the display assembly can coincide with the thickness of the front wall of the box base, thereby reducing the overall thickness of the air conditioner electric control box. By arranging the second notch part to connect the first notch part and the front wall side edge of the box base, the process of mounting the circuit board body on the box body can be realized, and the light emitting part is inserted into the first notch part at the same time, thereby improving the assembly efficiency.

[0018] In an optional technical solution, the circuit board is provided with a strong current rectifier filter circuit, a communication circuit and a BUCK circuit, the strong current rectifier filter circuit, the communication circuit and the BUCK circuit are all located on the upper part of the circuit board, and the main body part of the first pin element in the strong current rectifier filter circuit, the communication circuit and the BUCK circuit is arranged on the back of the circuit board.

[0019] The above-mentioned circuits all include high first pin elements, and the air conditioner electric control box is arranged at the front of the air conditioner indoor unit, the air conditioner electric control box is provided with a wind wheel motor, a motor gland and a refrigerant pipe of an indoor heat exchanger at the lower rear part, and the space at the lower part of the air conditioner electric control box is relatively cramped. Arranging the above-mentioned circuits on the upper part of the circuit board makes the main body part of the first pin element in these circuits all located on the back of the circuit board, which is beneficial to fully utilize the space inside the air conditioner electric control box and reduce the overall volume of the air conditioner electric control box. Moreover, the upper part of the air conditioner electric control box is not directly opposite to the refrigerant pipe, so the temperature on the outside of the upper part of the rear wall of the air conditioner electric control box is higher than that of the lower part of the rear wall. The first pin elements in the above-mentioned circuits have strong heat effects and can generate more heat, thereby causing the temperature of the upper area of the space inside the air conditioner electric control box to be relatively high. Even so, since the temperature on the outside of the upper part of the rear wall is relatively high, there will not be a large temperature difference between the inside and outside of the upper part of the rear wall, which is beneficial to control the risk of condensation on the rear wall of the air conditioner electric control box.

[0020] In an optional technical solution, the circuit board is provided with a fan drive circuit, and the fan drive circuit comprises three intelligent power modules which are arranged in a triangular shape.

[0021] The three intelligent power modules are arranged in a triangle mode, which is beneficial to increasing the distance of the three intelligent power modules, so that the three intelligent power modules can better exchange heat with air, so as to reduce the operation temperature of the intelligent power module and improve the reliability of the air conditioner electric control box.

[0022] In the optional technical solution, the circuit board is further provided with a buzzer circuit, an infrared receiving circuit and a WiFi control circuit, and the buzzer circuit, the infrared receiving circuit and the WiFi control circuit are located at the lower part of the circuit board.

[0023] The lower part of the air conditioner electric control box is located before a wind wheel motor, a motor gland and a heat exchanger refrigerant pipe, so the thickness of the lower part of the internal space of the air conditioner electric control box is small, the elements of the circuits are low in height, and the circuits are arranged at the lower part of the circuit board, so that the space of the lower part of the air conditioner electric control box can be fully utilized.

[0041] Embodiment one:

[0042] Figure 1 A three-dimensional disassembly view of the air conditioner electric control box provided by the embodiment one of the present application; Figure 2 A structure schematic view of the circuit board in the air conditioner electric control box provided by the embodiment one of the present application, omitting the lampshade and the fixing member; Figure 3 A structure schematic view of the circuit board in the air conditioner electric control box provided by the embodiment one of the present application, omitting the lampshade and the fixing member, viewed from another direction; Figure 4 A sectional view of the air conditioner electric control box provided by the embodiment one of the present application. As shown in Figures 1-4 The air conditioner electric control box provided by the embodiment one of the present application comprises a box body 100 and a circuit board 200 installed inside the box body 100, the circuit board 200 is provided with a display assembly 210 and a first pin element 221, the display assembly 210 comprises a display lamp 211, the lamp bead part of the display lamp 211 is located on the front surface of the circuit board 200 and protrudes outward relative to the front surface of the circuit board 200; the first pin element 221 comprises a main body part and a pin part; the height of the main body part is greater than three times the height of the lamp bead part; the main body part is connected to the circuit board 200 through the pin part; the main body part is located on the back surface of the circuit board 200 and protrudes outward relative to the back surface of the circuit board 200.

[0043] By arranging the display assembly 210 on the circuit board 200, the display assembly 210 can be integrated in the air conditioner electric control box to control the display lamp 211 to display information, without separately arranging a box body for the display driving circuit 213, and without separately connecting the display assembly 210 and the air conditioner electric control box, thereby shortening the assembly time. Moreover, by arranging the main body part of the first pin element 221 with a height greater than three times the height of the lamp bead part of the display lamp 211 on the back surface of the circuit board 200, the interval between the front surface of the circuit board 200 and the front wall of the air conditioner electric control box can be reduced, which is conducive to the contact between the display assembly 210 and the front panel of the air conditioner (not shown in the figure) and the clear display of relevant information.

[0044] It should be noted that the height of the lamp bead part of the display lamp 211 refers to the farthest distance between the side of the circuit board 200 on which the lamp bead part of the display lamp 211 is located and the lamp bead part of the display lamp 211 after the display lamp 211 is normally installed on the circuit board 200. The height of the main body part refers to the farthest distance between the side of the circuit board 200 on which the main body part of the pin element is located and the main body part of the pin element after the pin element is normally installed on the circuit board 200. In this application, the location of the certain element on the back and front of the circuit board 200 refers to the location of the main body part of the element on the back and front of the circuit board 200.

[0045] The first pin element 221 can include electrolytic capacitors, resistors, rectifiers and other electronic elements. In this embodiment, although the main body parts of the first pin element 221 are located on the back of the circuit board 200, it is not limited that the main body parts of all pin elements are located on the back of the circuit board 200. For example, the second pin element 222 with a height of the main body part less than or equal to three times the height of the lamp bead part can also be arranged on the front of the circuit board 200. In this application, the main body parts of the first pin element 221 with a height of the main body part greater than three times the height of the display lamp 211 are located on the back of the circuit board 200. Arranging the main body parts of the first pin element 221 on the back of the circuit board 200 can make the space on the back of the circuit board 200 relatively sufficient to arrange the main body parts of the first pin element 221 with a relatively large height in at least part of the area of the air conditioner control box.

[0046] In this embodiment, the front of the circuit board 200 is the side of the circuit board 200 facing the front wall of the air conditioner control box, and the back of the circuit board 200 is the side of the circuit board 200 facing the back wall of the air conditioner control box. The display lamp 211 is located on the front of the circuit board 200, and the display lamp 211 emits light, which is projected on the front panel of the wall-mounted air conditioner indoor unit (not shown in the figure) through the lampshade 212 described below to display relevant information.

[0047] As shown in FIGS. 1 and 2, the display assembly 210 can include a display lamp 211 and a first pin element 221 electrically connected to the display lamp 211. Figure 2 As shown in FIGS. 1 and 2, the display assembly 210 can include a display lamp 211 and a first pin element 221 electrically connected to the display lamp 211. Figure 3 As shown in FIGS. 1 and 2, the display assembly 210 can include a display lamp 211 and a first pin element 221 electrically connected to the display lamp 211.

[0048] By arranging the display driving circuit 213 on the back of the circuit board 200 and opposite to the display lamp 211, the area of the circuit board 200 occupied by the display driving circuit 213 and the display lamp 211 can be significantly reduced, thereby being beneficial to controlling the overall area of the circuit board 200 in the air conditioner control box, and the display driving circuit 213 is arranged opposite to the display lamp 211, the wiring distance between the display lamp 211 and the display driving circuit 213 can be shortened, the conductor length between the display lamp 211 and the display driving circuit 213 is reduced, and the cost of the air conditioner control box is reduced.

[0049] It should be noted that in the present application, the circuit is located on the front or back of the circuit board 200, which means that the main body of the electronic component constituting the circuit is located on the front or back of the circuit board 200.

[0050] Optionally, the display lamp 211 is an LED lamp or a lamp bead.

[0051] The LED lamp or the lamp bead is used as the display lamp 211, which can emit light with large light flux in a small space, so as to ensure that the pattern displayed through the lampshade 212 is clear on the front panel of the air conditioner.

[0052] Figure 5 The front view of the circuit board in the air conditioner control box is provided for the embodiment one of the present application, as shown in Figures 1-5 Optionally, the display assembly 210 is located at the lower part of the circuit board 200.

[0053] Since the air conditioner control box is applied to the wall-mounted air conditioner indoor unit and is located in front of the wind wheel motor, the motor gland 320 and the refrigerant pipe 331 of the indoor heat exchanger 330, the lower space of the air conditioner control box is relatively cramped. Such an arrangement means that the display driving circuit 213 is also located at the lower part of the air conditioner control box, and the electronic components of the display driving circuit 213 are relatively thin. By arranging the display assembly 210 at the lower part of the circuit board 200, the lower space in the air conditioner control box can be fully utilized. In addition, such an arrangement can also reduce the position of the display assembly 210 relative to the air conditioner control box, and further reduce the position of the display assembly 210 relative to the wall-mounted air conditioner indoor unit. When the user needs to observe the information of the display assembly 210, the user does not need to tilt the head at a large angle, thereby improving the user experience.

[0054] As shown in Figure 5 Optionally, the display assembly 210 comprises a lampshade 212, the lampshade 212 is configured to be attached to the front panel of the wall-mounted air conditioner indoor unit, the lampshade 212 is provided with a light-transmitting hole, and each display lamp 211 is arranged opposite to the light-transmitting hole.

[0055] By using the light-transmitting holes on the lampshade 212 and the corresponding display lights 211, the brightness of each light-transmitting hole can be controlled by each display light 211. By attaching the lampshade 212 and the circuit board 200 to the front panel, the lampshade 212 can be tightly attached to the inner side of the front panel, so that the pattern of the light-transmitting hole can be clearly presented on the front panel.

[0056] Specifically, in this embodiment, the lampshade 212 and the circuit board 200 are floating relative to each other. More specifically, a fixing member 214 for the display component 210 is fixedly connected to the circuit board 200. The fixing member 214 for the display component 210 can be fixed by passing a buckle 215 through a through hole on the circuit board 200. An elastic component (not shown in the figure) is installed on the fixing member 214 for the display component 210. The elastic component is a cylindrical helical compression spring. One end of the cylindrical helical compression spring abuts against the rear side of the lampshade 212, and the other end abuts against the front side of the fixing member 214. The cylindrical helical compression spring can push the lampshade 212 to fit against the front panel.

[0057] The light-transmitting holes on the lampshade 212 can be arranged in a double figure-eight pattern. The light-transmitting holes used to form each figure-eight can be arranged for a seven-segment digital display to display information such as the air conditioner temperature.

[0058] Of course, in another implementation, the lampshade 212 can be fixedly connected to and adhered to the front panel. For example, a groove can be provided on the back of the front panel, into which the lampshade 212 is embedded and fixed. The lampshade 212 can still be slidably connected to the fixing member 214 fixed to the circuit board 200. Thus, the light displayed by each indicator lamp 211 can still be largely confined to the area enclosed by the lampshade 212 and the fixing member 214 corresponding to that indicator lamp 211, thereby reducing light leakage.

[0059] like Figure 1 As shown, optionally, the box body 100 includes a box base 110 and a box cover 120. The circuit board 200 is mounted on the box base 110. The box base 110 is provided with a first notch 111 and a second notch 112. The first notch 111 is used to accommodate the lampshade 212 through which it passes. The lampshade 212 is configured to protrude from the box base 110. The second notch 112 connects the first notch 111 and the edge of the box base 110 facing the box cover 120. The box cover 120 is provided with a protrusion that covers the second notch 112.

[0060] By setting the first notch part 111 to accommodate the lampshade 212 to pass through, the lampshade 212 can protrude from the box seat 110, so in the air conditioner control box, the lampshade 212 can be prior to the front wall of the air conditioner control box to fit the front panel of the wall-mounted air conditioner indoor unit, so as to more clearly display information, on the other hand, the part of the display assembly 210 can coincide with the front wall thickness of the box seat 110, thereby reducing the overall thickness of the air conditioner control box. The second notch part 112 is arranged to communicate the first notch part 111 and the front wall side edge of the box seat 110, which can realize the process of mounting the circuit board 200 to the box body 100, and at the same time, the light emitting part is inserted into the first notch part 111, thereby improving the assembly efficiency.

[0061] Specifically, in the embodiment, the opening of the box seat 110 is to the right, and the box cover 120 is closed on the box seat 110 from right to left. The first notch part 111 is located at the lower part of the front wall of the box seat 110, so the second notch part 112 and the first notch part 111 jointly form a notch part opening to the right, so that the display assembly 210 can be inserted into the first notch part 111.

[0062] Figure 6 The rear view of the circuit board in the air conditioner control box provided by the embodiment of the utility model; as shown in Figure 6 Optionally, the circuit board 200 is provided with a strong current rectifier filter circuit 231, a communication circuit 232 and a BUCK circuit 233, the strong current rectifier filter circuit 231, the communication circuit 232 and the BUCK circuit 233 are all located at the upper part of the circuit board 200, and the main body part of the first pin element 221 in the strong current rectifier filter circuit 231, the communication circuit 232 and the BUCK circuit 233 is arranged on the back of the circuit board 200.

[0063] The above-mentioned circuits all include the first pin element 221 with high height, and the air conditioner control box is arranged at the front part of the wall-mounted air conditioner indoor unit, the air conditioner control box is provided with a wind wheel motor, a motor gland 320 and a refrigerant pipe 331 of an indoor heat exchanger 330 at the lower rear part, the space of the lower part of the air conditioner control box is relatively cramped, the above-mentioned circuits are arranged at the upper part of the circuit board 200, so that the main body part of the first pin element in these circuits is located on the back of the circuit board, which is beneficial to fully utilize the space inside the air conditioner control box and reduce the overall volume of the air conditioner control box. Moreover, the upper part of the air conditioner control box is not directly opposite to the refrigerant pipe 331, so the temperature of the outer side of the upper part of the rear wall of the air conditioner control box is relatively higher than that of the lower part of the rear wall. The first pin element 221 in the above-mentioned circuit has strong heat effect and can generate more heat, so as to cause the temperature of the upper area of the space inside the air conditioner control box to be relatively high. Even so, since the temperature of the outer side of the upper part of the rear wall is relatively high, there will not be a large temperature difference between the inside and outside of the upper part of the rear wall, which is beneficial to control the risk of condensation on the rear wall of the air conditioner control box.

[0064] In addition, the circuit including the first pin elements 221 is arranged on the upper portion of the circuit board 200, which facilitates the distance between the first pin elements 221 and the display driving circuit 213, and can improve the heat dissipation of the display driving circuit 213, thereby avoiding the problem that the air after absorbing heat from the elements of the display driving circuit 213 is blocked by the first pin elements 221 and is difficult to flow upward smoothly, the ambient air temperature of the display driving elements rises, and the risk of burning out of the display driving elements increases.

[0065] As shown in FIG. 2 and Figure 6 Optionally, the circuit board 200 is provided with a fan driving circuit 234, and the fan driving circuit 234 includes three intelligent power modules 2341 arranged in a triangular shape.

[0066] The three intelligent power modules 2341 are arranged in a triangular shape, which facilitates increasing the distance between the three intelligent power modules 2341, so that the three intelligent power modules 2341 can better exchange heat with the air, thereby reducing the operating temperature of the intelligent power modules 2341 and improving the reliability of the air conditioner electric control box.

[0067] Specifically, in the embodiment, the fan driving circuit 234 is located in the middle region of the circuit board 200 in the height direction, and the three intelligent power modules 2341 are arranged in a left-two-right-one triangular shape. The fan motor terminal 241 is arranged adjacent to the fan driving circuit 234. On the right edge of the circuit board 200, a temperature sensor terminal 242, an up-down air sweeping terminal 243, and a guide air driving motor terminal 244 are arranged in sequence. The temperature sensor terminal 242 is electrically connected with a temperature sensor, and the temperature sensor can include an indoor temperature sensor arranged at the air inlet of the wall-mounted air conditioner indoor unit, and an indoor coil temperature sensor arranged in the indoor coil of the indoor heat exchanger 330. The up-down air sweeping terminal 243 is electrically connected with an up-down air sweeping motor, and the guide air driving motor terminal 244 is electrically connected with a left-right air sweeping motor.

[0068] As shown in FIG. 2 and Figure 6 Optionally, the circuit board 200 is further provided with a buzzer circuit 235, an infrared receiving circuit 236, and a WiFi control circuit 237, and the buzzer circuit 235, the infrared receiving circuit 236, and the WiFi control circuit 237 are all located on the lower portion of the circuit board 200.
