[0028] In this embodiment, the first side edge 210 is provided towards the air inlet of the housing. The air entering the housing via the air inlet flows towards the back plate 200. When the flowing air passes through the guide plate 230 at the back plate 200, the air guide hole 231 at the guide plate 230 will guide the air flow, so that the air flow can smoothly enter the accommodation cavity 201. The air guide hole 231 communicates with the inner cavity of the box 300, so that the air can enter the inner cavity of the box 300, and the sensor 400 detects a humidity and / or a temperature and / or gas concentration of the air entering the inner cavity of the box 300. In this way, the air data detected by the sensor 400 can be accurate. The box 300 can be installed at the panel 100 or the back plate 200. The sensor 400 is installed inside the box 300. A control plate can be provided in the box 300. The control plate can be electrically connected to the sensor.

The sensor 400 is provided in the inner cavity of the box 300. The back plate 200 is provided with a first side edge extending along the length direction of the back plate 200. A side of the back plate 200 away from the panel 100 is provided with a guide plate 230 facing the first side edge 210, and the guide plate 230 is provided with an air guide hole 231 communicating with the accommodation cavity 201. The inner cavity of the box 300 communicates with the air guide hole 231, so that the air entering from the air guide hole 231 can enter the inner cavity of the box 300. In addition, the air guide hole 231 can guide the air flow, so that the air can enter the inner cavity of the box 300 smoothly. The sensor 400 is provided in the inner cavity, and the sensor 400 is configured to detect a humidity and / or a temperature and / or gas concentration of the air entering the inner cavity. In this way, the sensor 400 can accurately detect a humidity and / or a temperature and / or gas concentration of the air, and the problem that the airflow cannot pass through the inner cavity smoothly and causes inaccurate detection data of the sensor 400 can be avoided, thereby improving the reliability of the panel assembly 10.

[0030] As shown in FIG. 2 to FIG. 4, in an embodiment, the guide plate 230 is provided with a air guide surface 232, and the air guide surface 232 extends obliquely away from the first side edge 210. In an embodiment, the air guide surface 232 is provided with a first end and a second end opposite to the first end. The back plate 200 comprises a plate body and a boss provided at the plate body. The boss is provided at a side of the plate body away from the panel 100. The side plate 320 of the boss facing the first side edge 210 is the guide plate 230. The guide plate 230 is connected to the first end and the plate body. The second end is spaced apart from the plate body. The first end extends towards the second end to form the guide plate 230. The distance between the projection of the first end on the plate body and the first side edge 210 is smaller than the distance between the projection of the second end on the plate body and the first side edge 210. That is, the angle formed by the first side edge 210, the first end, and the second end is an obtuse angle. The first end is located between the first side edge 210 and the second end, so that the air guide surface 232 extends obliquely away from the first side edge 210.

[0031] It can be understood that when the air flows from the side close to the first side edge 210 to the side facing the air guide surface 232, the air guide surface 232 extends obliquely away from the first side edge 210, so that the air can pass through the air guide surface 232 of the guide plate 230 smoothly, and the air can enter the accommodation cavity 201 via the air guide hole 231 at the guide plate 230 smoothly. In this way, the air can enter the accommodation cavity 201 smoothly, so that the sensor 400 in the accommodation cavity 201 can accurately detect a humidity and / or a temperature and / or gas concentration of the air, and the problem that the airflow cannot pass through the inner cavity smoothly and causes inaccurate detection data of the sensor 400 can be avoided, thereby improving the reliability of the panel assembly 10.

[0032] As shown in FIG. 2 to FIG. 4, in an embodiment, the air guide hole 231 is a strip-shaped hole. The strip-shaped hole extends along a width direction of the back plate 200. The guide plate 230 is provided with a plurality of strip-shaped holes, and the plurality of strip-shaped holes are distributed at intervals on the guide plate 230 along the length direction of the back plate 200.

[0033] In an embodiment, the strip-shaped hole are provided at the guide plate 230. The strip-shaped hole can increase the air intake volume, and the strip-shaped hole extends along the width direction of the back plate 200. The first side edge 210 extends along the length direction of the back plate 200. That is, the extending direction of the strip-shaped hole is perpendicular to the first side edge 210. When the air flows from the side close to the first side edge 210 to the side facing the guide plate 230, the extending direction of the strip-shaped hole is parallel to the flow direction of the air, so that the air can enter the strip-shaped hole smoothly, that is, the air can enter the air guide hole 231 smoothly.

[0034] Furthermore, there are a plurality of strip-shaped holes, and the plurality of strip-shaped hole are distributed at intervals on the guide plate 230 along the length direction of the back plate 200, so that the air flowing from the side close to the first side edge 210 to the side facing the guide plate 230 can smoothly enter the accommodation cavity 201 along the plurality of strip-shaped holes. The plurality of strip-shaped holes increase the air intake volume, thereby making the air data detected by the sensor 400 more accurate.

[0035] As shown in FIG. 3 to FIG. 5, in an embodiment, the side of the box 300 facing the panel 100 is provided with an opening, a bottom plate 310 and / or a side plate 320 of the box 300 are provided with a through hole 330 communicating with the air guide hole 231.

[0036] It can be understood that the side of the box 300 facing the panel 100 is provided with an opening, and the panel 100 is provided with a window corresponding to the opening. The box 300 is detachably connected to the panel 100, and the detachable connection can be a bolt connection, or can be a clamping connection, which is not limited here. The bottom plate 310 may be provided with a through hole 330 communicating with the air guide hole 231, and the side plate 320 may also be provided with a through hole 330 communicating with the air guide hole 231, which can be set according to the actual needs. In this embodiment, both the bottom plate 310 and the side plates 320 are provided with the through holes 330. There may be a plurality of through holes 330 on the bottom plate 310, and there may also be a plurality of through holes 330 on the side plates 320. For convenience of description, the through hole 330 on the bottom plate 310 of the box 300 is the first through hole 331, and the through hole 330 on the side plate 320 of the box 300 is the second through hole 332. The first through hole 331 and the second through hole 332 communicate the accommodating cavity 201 with the inner cavity of the box 300. The accommodating cavity 201 communicates with the air guide hole 231, so that the air guide hole 231 communicates with both the first through hole 331 and the second through hole 332, and the air entering from the air guide hole 231 can enter the inner cavity of the box 300 through the first through hole 331 and the second through hole 332. In this way, the sensor 400 can detect a humidity and / or a temperature and / or gas concentration of the air entering the inner cavity of the box 300. By arranging the plurality of first through holes 331 and second through holes 332, the air intake amount entering the inner cavity of the box 300 can be increased, making the air data detected by the sensor 400 more accurate.

[0037] As shown in FIG. 2 to FIG. 4, in an embodiment, the backplane 200 is provided with a plurality of through holes 240 communicating with the through holes 330, and the through holes 330 are provided between the through holes 240 and the sensors 400. It can be understood that the through hole 240 is provided on the back plate 200, and the through hole 240 is located at the side of the air guide hole 231 and is provided at the boss, that is, the through hole 240 is provided at the side of the air guide hole 231 away from the first side edge 210. The air guided by the guide plate 230 can flow along the side away from the first side edge 210. When the air passes through the through hole 240 on the boss, the air can pass through the through hole 240, the accommodation cavity 201 and the through hole 330 in sequence, and then can enter the inner cavity of the box 300. In addition, the through hole 330 is provided between the through hole 240 and the sensor 400, and the through hole 240 is provided on the boss. The projections of the sensor 400 and the through hole 330 on the back plate 200 fall on the boss, and fall into the area where the plurality of the through holes 240 are located. In this way, the air can be prevented from bending around after the air enters the accommodation cavity 201, so that the air can smoothly enter the inner cavity of the box 300 from the through hole 330, thereby improving the smoothness of the air flow.

[0038] As shown in FIG. 2 to FIG. 4, in an embodiment, a rib 250 is provided at a side of the back plate 200 facing the panel 100, and the through hole 240 is located between the guide plate 230 and the rib 250. The rib 250, the guide plate 230, the box 300, the panel 100 and the back plate 200 are enclosed to form an air guide channel 260, and the air guide channel 260 is configured to guide air entering the air guide channel 260 into the through hole 330.

[0039] In an embodiment, the rib 250 can be arranged in a linear shape or in an arc shape. There may be a plurality of ribs 250. A frame is formed by an enclosure of the plurality of ribs 250 provided on the back plate 200 and the guide plate 230. The through hole 240 is provided in the area enclosed by the frame. The rib 250, the guide plate 230, the box 300, the panel 100 and the back plate 200 are enclosed to form an air guide channel 260. The air guide channel 260 can guide the air entering the air guide channel 260, so that the air in the accommodation cavity 201 can only flow towards the through hole 330 in the air guide channel 260. The air guide channel 260 is a part of the accommodation cavity 201. The air guide channel 260 can be adopted to avoid the situation that the air flows to other positions in the accommodation cavity 201 and causes the air to not smoothly enter the through hole 330, and the air guide channel 260 can make the air enter the inner cavity of the box 300 smoothly.

[0040] Furthermore, in order to improve the sealing performance of the air guide channel 260 and prevent air from flowing into the accommodation cavity 201 from the gap between the box 300 and the back plate 200, in an embodiment, a convex portion is provided at the bottom plate 310 of the box 300. The convex portion is provided in the area of the frame enclosed by the rib 250 and the guide plate 230 and is abutted against the rib 250. In this way, the gap between the box 300 and the back plate 200 can be reduced, and airtightness of the air guide channel 260 can be improved, thereby enabling the air entering the air guide channel 260 to flow into the inner cavity of the box 300.

[0041] As shown in FIG. 6 to FIG. 9, in an embodiment, the sensor 400 comprises a base plate 410 and a detection module 420 provided at the base plate 410. The box 300 is provided with a support platform 340 for supporting the base plate 410 and a fastening platform 350 for fastening the base plate 410.

[0042] In an embodiment, there can be a plurality of support platforms 340, and there can be a plurality of fastening platforms 350, which will not be limited here. In this embodiment, the base plate 410 is shaped in a square, and there are four support platforms 340. The four support platforms 340 are distributed on the bottom plate 310 of the box 300 in a rectangular shape, to support the four corners of the base plate 410. The fastening platform 350 is provided above the support platform 340 and is spaced apart from the support platform 340. The fastening platforms 350 are clamped on both sides of the base plate 410, so that the base plate 410 can be limited and fixed on the support platform 340. In this way, the installation stability of the base plate 410 can be ensured, that is, the installation stability of the sensor 400 can be ensured.

[0043] As shown in FIG. 10 to FIG. 12, in an embodiment, the back plate 200 is provided with a second side 220 extending along the length direction, and the second side 220 is opposite to the first side edge 210. The detection module 420 is provided at a side of the base plate 410 facing a bottom wall of the box 300, and a distance between the base plate 410 and the bottom wall of the box 300 gradually increases along a direction from the first side edge 210 to the second side 220.

[0044] In an embodiment, the direction from the first side edge 210 to the second side 220 is the width extension direction of the back plate 200. The air blown from the air conditioner indoor unit also flows along the width extension direction of the back plate 200.

The support platform 340 comprises a first support platform 341 and a second support platform 342. The distance between the projection of the first support platform 341 on the back plate 200 and the first side edge 210 is less than the distance between the projection of the second support platform 342 on the back plate 200 and the first side edge 210. The height between the first support platform 341 and the bottom wall of the box 300 is less than the height between the second support platform 342 and the bottom wall of the box 300. In this way, the base plate 410 is tilted on the first support platform 341 and the second support platform 342, and the flow space of the air flow gradually increases when the air flows from the first side edge 210 to the second side 220, that is, the flow space after the air enters the inner cavity of the box 300 gradually increases, thereby making the air flow smoother. In addition, the detection module 420 is located at the side of the base plate 410 facing the bottom wall of the box 300, and the detection module 420 can detect the flowing air, and the smooth flowing air ensures that the data detected by the detection module 420 is accurate.
