[0051] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0052] Reference below Figure 1-Figure 18 A face frame 10 according to an embodiment of a first aspect of the present invention is described.

[0053] like Figure 1 As shown, the face frame 10 according to the first embodiment of the utility model includes: a face frame body 11 and an electrical appliance cover 12.

[0054] Specifically, the face frame body 11 is formed with an installation opening 111 that passes through the face frame body 11 in the front-to-back direction; the electrical cover 12 is rotatably connected to the face frame body 11 for opening and closing the installation opening 111, and the electrical cover 12 is configured to cover the open opening 211 of the electric control box 20 when the installation opening 111 is closed.

[0055] For example, the electrical appliance cover 12 can be rotatably connected to the face frame body 11 through the rotating shaft 1201, or can be rotatably connected to the face frame body 11 through a hinge, the electrical appliance cover 12 can rotate relative to the face frame body 11 around a vertical axis, or can rotate relative to the face frame body 11 around a horizontal axis. The electrical appliance cover 12 can rotate between an open position and a closed position relative to the face frame body 11. When the electrical appliance cover 12 is in the closed position, the electrical appliance cover 12 not only closes the installation opening 111 but also covers the open opening 211 of the electric control box 20. When the electrical appliance cover 12 is in the open position, the electrical appliance cover 12 not only opens the installation opening 111 but also opens the open opening 211.

[0056] In this way, the opening 211 of the electric control box 20 can be opened and closed by using the electric cover 12 on the face frame 10, and there is no need to set up an additional cover of the electric control box 20, thereby reducing the number of parts. In addition, since the electric cover 12 can be rotatably connected to the face frame body 11, when the electric cover 12 is opened to the opening 211, the electric cover 12 can also maintain the connection with the face frame body 11, so that there is no need to hold the electric cover 12 by hand, and there is no risk of the electric cover 12 falling.

[0057] In addition, since the electrical cover 12 can open and close the opening 211 of the electrical control box 20, when repairing the electrical control box 20, the electrical cover 12 can be directly opened to repair the components on the electrical control board 22 in the electrical control box 20, which is simple to operate and convenient to repair.

[0058] Furthermore, the open opening 211 of the electric control box 20 is directly opposite to the mounting opening 111 of the face frame body 11 in the front-to-back direction. Furthermore, in a projection plane perpendicular to the front-to-back direction, the head projection of the open opening 211 is completely located within the projection range of the mounting opening 111. In this way, when the electrical cover 12 is opened, the components in the electric control box 20 can be completely exposed from the mounting opening 111, which is convenient for maintenance.

[0059] According to the face frame 10 of the embodiment of the utility model, the electrical cover 12 is rotatably connected to the face frame body 11, and the installation port 111 is opened and closed by rotating the electrical cover 12, and the opening 211 of the electric control box 20 is opened and closed at the same time. Therefore, when the opening 211 is opened, the electrical cover 12 can remain connected to the face frame body 11, and there is no risk of falling, which improves maintenance efficiency, reduces the number of parts, and improves assembly efficiency.

[0060] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the maximum angle at which the electrical cover 12 opens the mounting opening 111 is greater than or equal to 95°. That is, the rotation angle of the electrical cover 12 when it rotates from the closed position to the maximum angle position of the mounting opening 111 is greater than or equal to 95°. In other words, when the electrical cover 12 is rotatable between the open position and the closed position, the angle between the electrical cover 12 in the open position and the electrical cover 12 in the closed position is greater than or equal to 95°. In this way, the opening angle of the electrical cover 12 can be increased, providing a larger and wider space for maintenance, facilitating the repair and replacement of electrical components in the electrical control box 20, and facilitating the removal of the electrical control board 22. For example, the maximum opening angle of the electrical cover 12 can be 95°, 110°, 120°, 140°, 160° or 180°.

[0061] In some embodiments of the present invention, Fig.17 and Fig.18 As shown, a rotating shaft 1201 is formed on the electrical cover 12, and a mounting portion 112 is provided on the peripheral wall of the mounting opening 111. The mounting portion 112 includes a first convex rib 1121 and a second convex rib 1122 arranged front to back. The first convex rib 1121 and the second convex rib 1122 cooperate to define an axial hole and a notch connected to the axial hole, and the rotating shaft 1201 can be rotatably engaged in the axial hole.

[0062] For example Fig.17 As shown, a mounting portion 112 is provided on the right side wall of the mounting hole, and the mounting portion 112 includes a first rib 1121 and a second rib 1122 arranged front to back, the first rib 1121 and the second rib 1122 are arranged alternately in the up and down directions, a first groove is formed on the front side surface of the first rib 1121, the first groove penetrates the first rib 1121 along the up and down directions, and the cross-section of the first groove may be semicircular, a second groove is formed on the rear side surface of the second rib 1122, the second groove penetrates the second rib 1122 along the front and back directions, and the cross-section of the second groove may be semicircular, wherein the first groove and the second groove cooperate to define an axial hole, and a rotating shaft 1201 is formed on the electrical cover 12, and the rotating shaft 1201 cooperates in the axial hole.

[0063] Furthermore, the mounting portion 112 may include two second convex ribs 1122, and the two second convex ribs 1122 may be respectively arranged on the upper and lower sides of the first convex rib 1121. Thus, the stability of the mounting portion 112 and the rotating shaft 1201 can be further improved.

[0064] Furthermore, the number of mounting parts 112 can be multiple, and the multiple mounting parts 112 are arranged at intervals along the axial direction of the rotating shaft 1201. For example, the number of mounting parts 112 can be two, three, four, five or more, etc. The number of rotating shafts 1201 can also be multiple, and the multiple rotating shafts 1201 correspond to the multiple mounting parts 112 one by one and are rotatably connected.

[0065] When installing the electrical cover 12 on the face frame body 11, the rotating shaft 1201 on the electrical cover 12 can be aligned with the notch position defined by the cooperation of the first convex rib 1121 and the second convex rib 1122, and then the rotating shaft 1201 can be pressed into the shaft hole between the first convex rib 1121 and the second convex rib 1122. During the assembly process, the first convex rib 1121 and the second convex rib 1122 can undergo elastic deformation, making it easier for the rotating shaft 1201 to be pressed into the shaft hole.

[0066] In this embodiment, a mounting portion 112 having a first convex rib 1121 and a second convex rib 1122 is provided, and the first convex rib 1121 and the second convex rib 1122 cooperate to define an axial hole and a notch connected to the axial hole. The notch can facilitate the insertion of the rotating shaft 1201 into the axial hole, thereby improving the assembly efficiency between the electrical cover 12 and the face frame body 11 and realizing a detachable connection between the electrical cover 12 and the face frame body 11.

[0067] It should be noted that when the mounting portion 112 is formed on the side wall of the mounting opening 111, the opening angle of the electrical cover 12 is affected by the degree of interference between the electrical cover 12 and the step on the right side of the mounting portion 112. When the interference is smaller, the opening angle of the electrical cover 12 is larger, which can provide more space for maintenance.

[0068] In some embodiments of the present invention, Figure 11-13 As shown, the electrical cover 12 includes a cover plate 121 , a fireproof plate 122 and an insulating plate 123 which are sequentially stacked and connected along the thickness direction, and the cover plate 121 is arranged on a side of the fireproof plate 122 away from the electrical control box 20 .

[0069] That is, the electrical cover 12 includes a cover plate 121, a fireproof plate 122 and an insulating plate 123, which are sequentially arranged and connected in a front-to-back direction, wherein the insulating plate 123 is arranged on a side of the fireproof plate 122 facing the electrical control box 20 (e.g., the rear side of the fireproof plate 122), and the cover plate 121 is arranged on a side of the fireproof plate 122 facing away from the electrical control box 20 (e.g., the front side of the fireproof plate 122). By making the electrical cover 12 comprise three layers of plates, the structural strength of the electrical cover 12 can be improved.

[0070] Among them, the insulating plate 123 is an insulating plate body, for example, the insulating plate 123 can be a plastic plate, and the insulating plate 123 is arranged on the side of the electrical cover 12 facing the electrical control box 20. When the electrical cover 12 covers the open opening 211 of the electrical control box 20, the open opening 211 is covered by the insulating plate 123. In this way, the insulating plate 123 can isolate the electrical control board 22 in the electrical control box 20 from external components, thereby improving the insulation performance of the electrical control box 20.

[0071] The fireproof plate 122 may be a fireproof sheet metal part. By arranging the fireproof sheet metal part in the electrical appliance cover 12, the fireproof performance of the electrical appliance cover 12 may be improved, the safety performance of the electrical appliance cover 12 may be improved, and the structural strength of the electrical appliance cover 12 may be further improved.

[0072] The cover plate 121 may be a plastic part, which can facilitate the processing of the cover plate 121 and reduce costs, and can also improve the insulation performance of the electrical cover 12 .

[0073] In this embodiment, the electrical appliance cover 12 includes a stacked cover plate 121, a fireproof plate 122 and an insulating plate 123, so as to improve the structural strength, fireproof performance and insulation performance of the electrical appliance cover 12, reduce the number of parts and components, and improve assembly efficiency.

[0074] In one embodiment of the present invention, Figure 11-13 As shown, the fireproof board 122 is snap-connected with at least one of the cover plate 121 and the insulating plate 123. That is, the fireproof board 122 can be snap-connected only with the insulating plate 123, the fireproof board 122 can also be snap-connected only with the cover plate 121, or the fireproof board 122 can be snap-connected with both the cover plate 121 and the insulating plate 123. In this way, the snap-connection between the fireproof board 122, the cover plate 121 and the insulating plate 123 can improve the assembly efficiency, and can also facilitate maintenance and replacement. Among them, the snap-connection structure between the fireproof board 122, the cover plate 121 and the insulating plate 123 includes but is not limited to a hook, a slot, a hole, a buckle, etc.

[0075] In one example of the present invention, the fireproof board 122 has a flange 1222 bent toward the insulating board 123, a first buckle 1223 is formed on the flange 1222, and a second buckle 1223 is formed on the cover plate 121 extending toward the fireproof board 122, and the first buckle 1223 is engaged with the second buckle.

[0076] In this embodiment, a flange 1222 is formed on the edge of the fireproof plate 122, and the flange 1222 can further strengthen the structural strength of the fireproof plate 122 and the structural strength of the electrical appliance cover 12. In addition, a first buckle 1223 is formed on the flange 1222 and a second buckle is provided on the cover plate 121, so that the cover plate 121 and the fireproof plate 122 can be snapped together at the peripheral position, and the snap-fitting structure is simple and convenient.

[0077] Furthermore, there can be multiple first buckles 1223, which are arranged at intervals along the circumference of the fireproof board 122, and there can be multiple second buckles, which correspond to and engage with the multiple first buckles 1223. In this way, the connection reliability between the fireproof board 122 and the cover plate 121 can be further improved.

[0078] Furthermore, the first buckle 1223 protrudes along the thickness direction of the flange 1222 in a direction away from the insulating plate 123. The first buckle 1223 can be directly stamped on the flange 1222, so that the processing is convenient and the molding difficulty of the first buckle 1223 is reduced.

[0079] In one example of the present invention, the fireproof board 122 includes a main board 1221 and a flange 1222, the flange 1222 is connected to the periphery of the main board 1221 and extends toward the side where the insulating board 123 is located, the flange 1222 is formed with a clamping protrusion 1224, and the periphery of the insulating board 123 is clamped between the clamping protrusion 1224 and the main board 1221. Thus, the structure is simple, and the fireproof board 122 and the insulating board 123 can be connected by clamping.

[0080] For example Fig.12 and Fig.13 As shown, the fireproof board 122 includes a main board 1221 and a flange 1222. The main board 1221 is in the shape of a flat plate which is arranged vertically and extends left and right. The flange 1222 extends along the circumference of the main board 1221. The flange 1222 is connected to the circumference of the main board 1221 and extends backward. The insulating board 123 is arranged on the inner side of the flange 1222. A clamping protrusion 1224 extending toward the inner side of the flange 1222 is formed on the flange 1222. In the direction from the insulating board 123 toward the main board 1221, the side surface of the clamping protrusion 1224 facing away from the flange 1222 is an inclined surface extending obliquely away from the flange 1222. In this way, the insulating board 123 can be easily inserted into the inner side of the flange 1222 and clamped between the clamping protrusion 1224 and the main board 1221.

[0081] In a specific example of the present invention, the flange 1222 forms an opening that passes through the flange 1222 in the thickness direction, one end of the clamping protrusion 1224 is connected to the edge of the opening that is away from the main board 1221, and the other end extends obliquely toward the main board 1221. In this way, the clamping protrusion 1224 is formed into a cantilever structure, thereby simplifying the structure of the clamping protrusion 1224 and facilitating the molding and processing of the clamping protrusion 1224.

[0082] like Fig.12 and Fig.13 As shown, the main board 1221 is generally a rectangular plate, and flanges 1222 are formed on the upper peripheral edge, the lower peripheral edge and the left peripheral edge of the main board 1221, wherein the flange 1222 located on the upper peripheral edge of the main board 1221 is formed with an opening, which is a rectangular hole, and a clamping protrusion 1224 is provided on the rear side of the clamping hole, and the rear end of the clamping protrusion 1224 is connected to the rear side wall of the opening, and the front end of the clamping protrusion 1224 is away from the flange 1222 and extends obliquely toward the insulating board 123. Further, there are multiple clamping protrusions 1224, and the multiple clamping protrusions 1224 are arranged at intervals along the circumference of the main board 1221, thereby further improving the reliability of the clamping connection between the fireproof board 122 and the insulating board 123.

[0083] The air conditioner indoor unit 100 according to the second embodiment of the utility model comprises an electric control box 20 and a face frame 10 according to the first embodiment of the utility model. The electric control box 20 comprises a box body 21 and an electric control board 22, the front side of the box body 21 is open to form an open opening 211, and the electric control board 22 is arranged in the box body 21; the face frame 10 is arranged at the front side of the electric control box 20, and the electric cover 12 covers the open opening 211 when closing the installation opening 111, and opens the open opening 211 when opening the installation opening 111.

[0089] Furthermore, a fixing column extending toward the installation opening 111 may be formed in the box body 21 , and a second fixing hole is formed on the fixing column, so that the box body 21 and the electrical appliance cover 12 can be conveniently fastened and connected.

[0090] Furthermore, a raised boss is formed on the side surface of the electrical cover 12 facing away from the box body 21, and the boss extends in a ring shape along the circumference of the first fixing hole. The fastener is inserted into the first fixing hole and the second fixing hole, and the end face of the fastener facing away from the box body 21 does not exceed the end face of the boss.

[0091] In some embodiments of the present invention, the electric control board 22 is detachably connected to the box body 21 , and the electric control board 22 is configured to be taken out from the installation opening 111 .

[0092] It should be noted that in the prior art, when the electric control board needs to be repaired, the electrical cover needs to be disassembled, because the electric control box is relatively large, and the opening of the face frame cannot refer to the design opening of the electric control box. Therefore, during the maintenance process, after opening the electrical cover, it is still impossible to open the electric control box from the face frame to repair the electric control board, and the face frame must be disassembled for maintenance, which is particularly troublesome. In addition, during the disassembly process, it is easy to damage the appearance of the air conditioner indoor unit, and it may also affect the stability of the air conditioner; in addition, since many parts need to be disassembled, the maintenance time is too long and the efficiency is relatively low.

[0093] In this embodiment, the electric control board 22 is detachably connected to the box body 21, and the electric control board 22 can be removed. In this way, when maintenance is needed, the electrical cover 12 can be opened by rotating to open the opening 211 of the electric control box 20. Since there are no other parts blocking the electric control board 22, the electric control board 22 can be taken out of the box body 21 for maintenance. This can reduce the disassembly and assembly time, improve the maintenance efficiency, avoid affecting the appearance of the air-conditioning outdoor unit, and ensure the stability of the air conditioner.

[0094] Furthermore, in the projection plane perpendicular to the front-rear direction, the projection of the electric control board 22 is located within the projection of the opening 211, and the projection of the opening 211 is located within the projection of the installation opening 111. This makes it easy to remove the electric control board 22 from the installation opening 111 of the face frame 10.

[0095] In some embodiments of the utility model, the electric control board 22 is connected with a power line 23, a stopper 24 is sleeved on the power line 23, a fixing groove 212 is formed in the box body 21, and the stopper 24 is arranged in the fixing groove 212. Thus, the power line 23 can be fixed to the box body 21 by the stopper 24, so as to prevent the power line 23 from being pulled out and disconnected from the electric control board 22 due to force. In this way, compared with the technical solution of pressing the power line 23 by the wire pressing plate in the prior art, the present embodiment can reduce the wire pressing plate, reduce the cost, and reduce the management cost of parts.

[0096] The power line 23 can be electrically connected to the electric control board 22 through a terminal block, and the power line 23 can include a first power line 23 and a second power line 23, the first power line 23 is the power line 23 of the air conditioner outdoor unit, and the second power line 23 is the power line 23 of the air conditioner indoor unit 100. The number of the blocks 24 can correspond to the number of the power lines 23.

[0097] In addition, since a separate box cover is not provided for the open opening of the box body, when the electrical cover opens the open opening and the installation opening, the electric control board and the wiring connected to the electric control board can be directly seen. Therefore, when the air-conditioning indoor unit 100 of this embodiment is assembled, the temperature sensing probe of the indoor heat exchanger and the wiring terminals for connecting to the display box provided on the panel 50 do not need to be pre-positioned on the fixing clip in advance, but can be directly installed on the face frame 10 of this embodiment to arrange the temperature sensing wires and then connect the wiring terminals on the panel.

[0098] The following will refer to Figure 1-Figure 3 An air conditioner indoor unit 100 according to a specific embodiment of the present invention is described.

[0099] Reference Figure 1 The air conditioner indoor unit 100 includes a chassis 40, a face frame 10, a panel 50, a heat exchanger 30, an air guide plate 60 and an electric control box 20. The face frame 10 is arranged at the front side of the chassis 40, the panel 50 can be at the front side of the face frame 10 and is rotatably connected to the panel 50, the heat exchanger 30 is arranged between the chassis 40 and the face frame 10, and is used for heat exchange of air entering the air conditioner indoor unit 100, and the air guide plate 60 is arranged at the air outlet position, and is used for opening and closing the air outlet and adjusting the air outlet direction. The electric control box 20 is arranged on the chassis 40, and the electric control box 20 includes a box body 21 and an electric control board 22, the front side of the box body 21 is open and forms an open port 211, and the electric control board 22 is arranged in the box body 21.

[0100] The face frame 10 is arranged on the front side of the chassis 40 and the electric control box 20 . The face frame 10 includes a face frame body 11 and an electrical cover 12 . A mounting opening 111 is formed on the face frame body 11 . The mounting opening 111 is generally rectangular. The electrical cover 12 can be rotatably disposed at the mounting opening 111 .

[0101] The electrical cover 12 includes a cover plate 121, a fireproof plate 122 and an insulating plate 123 arranged in layers, the fireproof plate 122 is a fireproof sheet metal part, the insulating plate 123 is an insulating plastic part, and the cover plate 121 can be a material part. The fireproof plate 122 is connected to the cover plate 121 by snapping, and the fireproof plate 122 is connected to the insulating plate 123 by snapping. When the electrical cover 12 closes the installation opening 111 and the opening 211, the electrical cover 12 is fastened to the box body 21 by fastening screws.

[0102] When the electrical appliance cover 12 closes the installation opening 111 , the opening opening 211 of the electrical control box 20 can be closed synchronously. When the electrical appliance cover 12 opens the installation opening 111 , the opening opening 211 of the electrical control box 20 can be opened synchronously.

[0103] Among them, the size of the electric control box 20 of this embodiment can be 148.5mm×55.8mm, compared with the size of the electric control box 20 in the prior art of 193.5mm×67.3mm. This embodiment can facilitate the removal of the electric control board 22 from the open opening 211 and the installation opening 111 without disassembling the face frame 10, making maintenance more convenient.

[0104] According to the air conditioner indoor unit 100 of the utility model embodiment, when the electric control board 22 needs to be inspected, the fastening screws on the electric cover 12 can be removed. Due to the step on the right side of the mounting opening 111, the electric cover 12 can be opened by a hinge to an angle of at least 95°. The larger the angle, the wider the space can be for inspection. At the same time, since the electric cover 12 is directly mounted on the hinge (mounting portion 112) of the face frame 10, there is no possibility of scratches due to falling. At the same time, after the electric cover 12 is opened, there is no other parts blocking the electric control board 22, so the electric control board 22 can be smoothly taken out of the electric control box 20 for inspection.
