Description

Technical Field

[0001] The utility model relates to the technical field of washing machine hatches, in particular to a drum washing machine hatch. Background Art

[0002] Washing machines are divided into two types: drum type and pulsator type. Pulsator washing machines remove stains through the mutual friction of the clothing fabrics themselves, while drum washing machines use the rotation of the drum to drive the clothing in parabolic motion, and achieve the purpose of removing stains by beating the clothing. Friction washing causes more serious wear and tear on the surface of clothing, while beating washing has an advantage in fabric protection. Therefore, drum washing machines have been very popular in recent years.

[0003] The drum washing machine drives the clothes to rotate at high speed during operation, which will cause the clothes to impact the door, which is easy to cause the door to open. Therefore, a self-locking mechanism needs to be set for the door. At present, spring locks are commonly used, which are easy to open when subjected to large impact forces and have low safety. Therefore, those skilled in the art provide a drum washing machine door to solve the problems raised in the above background technology. Utility Model Content

A spring groove 37 is opened in the middle of the bottom of the fixed groove 34. A reset spring 39 is fixedly installed in the spring groove 37. The reset spring 39 is fixedly connected to the bottom surface of the magnetic block 38. The adsorption magnetic force of the electromagnet 36 and the magnetic block 38 is greater than the deformation force of the reset spring 39 The magnetic block 38 is larger than the gravity generated by itself, so that the elastic deformation of the reset spring 39 is used to push the magnetic block 38 to slide on the positioning rod 35 in a directional manner. A limit rotating rod 33 is arranged in the middle of the positioning seat 32. The limit rotating rod 33 can rotate freely in the positioning seat 32.
