Problems solved by technology

However, since the photosensitive element and the LED light are located on the same side, the light emitted by the LED light will be transmitted laterally to the photosensitive element, resulting in horizontal light guide, which will cause the photosensitive element to be interfered by the light of the LED light, and the true intensity of the external light cannot be correctly judged. , so it is impossible to accurately feed back the light intensity signal to the display control circuit
However, in related technologies, there may be gaps between the top surface of the lamp holder of the LED lamp and the front panel of the air conditioner, and between the bottom surface of the lamp holder and the circuit board, resulting in the leakage of LED light.

Embodiment 1

[0086] For clarity of description, in this embodiment, the shade 32 is marked with 32a. The shading member 32a is an at least part elastic element, that is to say, at least a part of the shading member 32a is elastic, wherein the elastic part abuts against the panel 1 so that the shading member 32a, the circuit board 3 and the panel 1 are formed to form a The above-mentioned sealed cavity 33 is used to prevent light interference and pollution such as dust in the air. In the present invention Figure 1-Figure 8 And in the description of the corresponding embodiments, the shading member 32a according to the present embodiment is taken as an example for specific description, that is, it elastically stops against the panel 1 . Of course, those skilled in the art can understand that the various light-shielding elements 32 to be described in the following embodiments can replace Figure 1-Figure 8 The shading member 32a in is assembled with other components of the air conditioner ...

Embodiment 2

[0094] For clarity of description, in this embodiment, the shade 32 is marked with 32b. The shading member 32b is a hollow non-elastic pipe, such as a rigid pipe, and the two ends of the pipe 32b are sealed and connected to the panel 1 and the circuit board 3 respectively. Such as Figure 12 As shown, one end of the shading member 32 adjacent to the panel 1 is abutted against the panel 1 through the first sealing member 34b, and the other end is connected to the circuit board 3 by glue, snap connection or screw thread. Optionally, the first sealing member 34b is a sealing ring, wherein the inner diameter of the first sealing member 34b is smaller than the inner diameter of the pipe 32b, and the outer diameter is greater than or equal to the outer diameter of the pipe 32b, so that the pipe 32b and the panel 1 can be well sealed between to prevent light leakage.

[0095] In a specific example, such as Figure 12 As shown, the shade 32b may be a cylindrical tube. Certainly, i...

Embodiment 3

[0100] For clarity of description, in this embodiment, the shade 32 is marked with 32c. Such as Figure 13 As shown, the air-conditioning indoor unit further includes: an elastic member 34c, which is arranged between the circuit board 3 and the shading member 32c to constantly push the shading member 32 against the panel 1, that is to say, the elastic member 34c is always opposite to the shading member 32c. An elastic force tending to the panel 1 is provided, whereby the sealing between the light-shielding member 32c and the panel 1 can be realized, thereby forming the above-mentioned sealed chamber.

[0101] Specifically, such as Figure 13 As shown, the shading member 32 may include: a first shading cylinder 321c and a second shading cylinder 322c, the first shading cylinder 321c covers the outside of the photosensitive element 31 and passes through the circuit board 3 in a sealed manner, that is to say, the first shading cylinder 321c The end of 321c away from the panel 1...

Abstract

The invention discloses an indoor unit of an air conditioner. The indoor unit comprises a face frame, a panel, a display assembly and a circuit board. A mounting space is defined between the panel and the face frame; the display assembly is arranged in the mounting space; the circuit board is arranged in the mounting space and is adjacent to the panel, a light-sensitive element is arranged on the circuit board, a light-proof shading component is arranged between the circuit board and the panel, a sealed cavity is jointly defined by the shading component, the circuit board and the panel, the light-sensitive element is positioned in the sealed cavity, and light rays transmitted from the panel can be received and detected by the light-sensitive element. The indoor unit of the air conditioner in an embodiment of the invention has the advantages that the indoor unit is provided with the sealed cavity, so that only the light rays transmitted from the panel can be received by the light-sensitive element, the light-sensitive element can be prevented from being disturbed by light rays from other positions such as LED lamps, the intensity of the external light rays can be accurately judged, and light intensity signals can be accurately fed to a display control circuit on the circuit board.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner indoor unit. Background technique [0002] The existing air-conditioning indoor unit includes a display assembly, a circuit board, an LED lamp arranged on the circuit board, and a photosensitive element located on the same side of the LED lamp. The photosensitive element collects the external light intensity signal entering from the panel, and transmits the light intensity signal to the display control circuit. However, since the photosensitive element and the LED light are located on the same side, the light emitted by the LED light will be transmitted to the photosensitive element horizontally, resulting in horizontal light guide, which will cause the photosensitive element to be interfered by the light of the LED light, and the true intensity of the external light cannot be correctly judged. , so it is impossible to accurately feed back the light intensity s...
