Problems solved by technology

Since the first door part and the second door part are only combined through the welding force between the butt surfaces, that is, the combination of the welding force between the surfaces, and the degree of tightness of this combination has a certain degree of chance, the weld is easy to Problems with cracking and separation
In addition, since the welding surfaces of the first door part and the second door part are at the same level, impurities and air are prone to appear in the welding seam, thus affecting the sealing effect of the welding seam

Abstract

The invention discloses a welding structure of a washer door frame. The welding structure comprises a first frame body and a second frame body which are connected by welding, a first group of welding ribs are arranged on the first frame body, a second group of welding ribs in one-to-one correspondence to all the welding ribs in the first group in position are arranged on the second frame body, one pair of position-corresponding welding ribs in the first and second groups of welding ribs are a broad welding rib and a narrow welding rib respectively, and the first frame body is connected with the second frame body by welding by means of inserting the narrow welding ribs into the board welding ribs. Due to the arrangement of the narrow welding ribs and the broad welding ribs, the first frame body and the second frame body are welded into a whole by insertion matching of the narrow welding ribs and the board welding ribs, binding force of the narrow welding ribs and the board welding ribs can be increased by the welding manner, and reliability and leakproofness of welding joints are improved.

Description

technical field [0001] The invention relates to the field of drum washing machine accessories, in particular to a welding structure of a door frame of a washing machine and a welding method adopted for the welding structure. Background technique [0002] The door frame of the washing machine is a common accessory of a drum washing machine. Its function is to prevent the water in the drum from overflowing and to facilitate the user to keep the running state of the washing machine at any time.
