Abstract

The invention discloses a waterproof PCB (Printed Circuit Board) box, which comprises a box cover, wherein a front panel and / or a bottom panel of the box cover are / is provided with a plurality of heat dissipation holes. The characteristics lie in that water retaining structures are arranged at the heat dissipation holes, wherein the water retaining structure at the bottom panel comprises a plurality of first water retaining pieces which are obliquely arranged in a shutter manner, and adjacent two first water retaining pieces define a first heat dissipation hole; and the water retaining structure at the front panel comprises a plurality of second water retaining pieces which are uniformly set and obliquely arranged, and adjacent two second water retaining pieces define a second heat dissipation hole. The beneficial effects are that the waterproof performance of a driving board box or a driving board box cover is improved to the maximum extent while the heat dissipation performance of a driving board is ensured through additionally arranging the water retaining structures in the heat dissipation holes, and the safety performance of a product is enhanced.

Description

technical field [0001] The present invention relates to a PCB (Printed Circuit Board, printed circuit board, abbreviated as PCB in Chinese) board box, specifically, to a waterproof PCB board box and a washing machine with the board box. Background technique [0002] Due to the impact of the working environment, when electrical components such as computer boards, power boards, and driver boards are installed on household appliances such as washing machines and dishwashers, it is inevitable that they will come into contact with water or be soaked by water. As we all know, once the electrical components are soaked in water, a short circuit may occur, causing equipment and even houses to catch fire, causing safety accidents. In order to eliminate potential safety hazards, such electrical devices are usually installed on the equipment with the help of computer board boxes, power board boxes, drive board boxes and corresponding box covers, etc., which can waterproof the electrical...
