air conditioner indoor unit

Abstract

The invention discloses an indoor unit of an air conditioner. The indoor unit comprises a face frame, a panel and a circuit board. A side of the face frame is open; the open side of the face frame is closed by the panel, and a mounting space is defined between the panel and the face frame; the circuit board is arranged in the mounting space and is adjacent to the panel, a light-proof shading component and a light-sensitive element are arranged on the circuit board, the light-sensitive element is arranged in the shading component, light rays transmitted from the panel can be received and detected by the light-sensitive element, and the shading component is an element with at least one elastic portion. The indoor unit of the air conditioner in an embodiment of the invention has the advantages that the shading component is provided with elastic portions, the elastic portions are butted onto the panel, accordingly, spaces between the shading component and the panel can be sealed, the light-sensitive element can be prevented from being disturbed by light rays and can be prevented from being contaminated by dust and the like in air, the intensity of the external light rays can be accurately judged by the light-sensitive element, 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...

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
