Problems solved by technology

[0016] That is, when the paint is applied to the top surface of the printed circuit board assembly 520, the paint cannot be evenly applied to the LED substrate 620 provided between the bottom surface of the lamp tube box 610 and the top surface of the printed circuit board assembly 520.
In this case, water or the like may permeate into the light emitting diode substrate 620, causing malfunction of the display control panel 500.

Abstract

The display part of washing machine includes printed circuit board assembly with various circuit elements, LED base board with LED's, and lamp tube box around the LED base board. The display part of washing machine features the lamp tube box with several inflow ports for paint to flow into. The improved washing machine display part has improved lamp tube box to make moisture-proof and waterproof paint coated to the top of the printed circuit board assembly including the LED base board to prevent the penetration of water and moisture effectively.

Description

technical field [0001] The invention relates to a washing machine, in particular to a display part of the washing machine. More specifically, the present invention improves the lamp box of the display part, so that the coating is evenly coated on the top surface of the printed circuit board assembly including the LED substrate in order to prevent moisture and water. Background technique [0002] Generally, the washing machine washes the laundry by vigorously agitating the washing water, utilizing the frictional force between the laundry and the water flow, the dissolution of the detergent, and the impact of the washing tub 200 on the laundry. [0003] figure 1 It is a cross-sectional view of the internal structure of a common washing machine. As shown, the washing tub 200 is located inside the housing 100 . The top surface of the housing 100 is provided with a top cover 300 . [0004] A lower portion of the top cover 300 is provided with a front panel 400 having a certai...
