Washing machine

Abstract

The present invention realizes a washing machine in which even if a fire occurs in a portion of a control printed circuit board through which a large current flows, the fire does not spread to an upper frame or a panel member. In this washing machine, a power supply control printed circuit board (control printed circuit board) that is accommodated in an upper casing mounted on the main body of the washing machine and controls the operation of the washing machine is housed in a first boat. In the state of the board, the power supply control printed circuit board unit (control printed circuit board unit) that is waterproofed is formed by filling the potting material in the state of the board, and the relay (electrical component) that flows through the large current mounted on the power supply control printed circuit board ), the triac (electrical component), the female connector (connector part), and the male connector (connector part) are covered with a cover (metal member).

Description

technical field [0001] The present invention relates to a washing machine having a control printed circuit board unit in which the control printed circuit board is waterproofed. Background technique [0002] Conventionally, such a washing machine generally has the structure shown in FIG. 4 (for example, refer to Japanese Patent Application Laid-Open No. 5-123492). [0003] Hereinafter, its structure will be described using FIG. 4 . An upper frame 3 is installed on the upper part of the washing machine main body 2 containing the washing tub 1, and a clothes inlet 4 is formed in the approximate center of the upper frame 3, and the clothes inlet 4 is covered by a cover 5 so that it can be opened and closed freely. In addition, an electromagnetic water supply valve 6 for controlling water supply and a water inlet member 7 communicating with the electromagnetic water supply valve 6 to supply water into the washing tub 1 are built in the rear part of the upper frame body 3, and t...

AI Technical Summary

Problems solved by technology

[0005] However, in the above-mentioned conventional structure, due to reasons such as defective parts of the electrical parts 15, looseness of the connector part 14 or connection / poor contact, entry of water or steam, etc., in case of a fire from the electrical part 15 and the connector part 14 At this time, since the front panel member 11 is formed of thermoplastic resin such as PP (polypropylene) or ABS (acrylonitrile-butadiene-styrene), there is a possibility that the fire from the electrical parts 15 and the connector part 14 will spread to the upper frame. Problems with body 3, front panel member 11, etc.
