Problems solved by technology

[0002] Household appliances such as refrigerators and air conditioners use background lights to display certain working states, functions, and numbers. At present, the general background light bar includes a printed circuit board, and the front of the printed circuit board is connected to at least one LED light and at least one resistor. The background light bar is not waterproof and moisture-proof
In actual use or in an environment with a lot of water vapor, such as in a refrigerator, water vapor will enter the interior of the backlight, causing the circuit of the backlight to malfunction.

Abstract

The invention relates to a backlight bar and relates to structures of backlights of household electric appliances. The backlight bar comprises a printed circuit board. At least one LED light and at least one resistor are connected to the front of the printed circuit board, and waterproof adhesives are respectively arranged on the front of the printed circuit board, outer surfaces of the LED lights and outer surfaces of the resistors. By the aid of the waterproof adhesives respectively arranged on the front of the printed circuit board, outer surfaces of the LED lights and outer surfaces of the resistors, damages of circuits of the backlight due to water vapor are avoided effectively, and normal use of the backlight is guaranteed. The backlight bar can be used in a refrigerator.

Description

technical field [0001] The invention relates to the structure of a background light of a household appliance. Background technique [0002] Household appliances such as refrigerators and air conditioners use background lights to display certain working conditions, functions, and numbers. At present, the general background light bar includes a printed circuit board, and the front of the printed circuit board is connected to at least one LED light and at least one resistor. The background light bar is not waterproof and moisture-proof. However, in actual use or in an environment with a lot of water vapor, such as in a refrigerator, water vapor will enter the interior of the backlight, causing the circuit of the backlight to malfunction. Contents of the invention [0003] The object of the present invention is to provide a waterproof and moisture-proof background light bar in order to overcome the deficiencies of the prior art. [0004] The object of the present invention i...
