Embodiment Construction

[0012] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The embodiments described below can be changed into various other forms, and the scope of the present invention is not limited to the embodiments described below. The embodiments of the present invention are presented in order to fully explain the present invention to those skilled in the art.

[0013] The embodiment of the present invention proposes a door hinge for a washing machine. The door hinge uses a steel wire to adjust the elastic force of the spring. The action principle of adjusting the door closing speed through the spring is simple, the manufacturing unit price is relatively low, and it can be easily assembled. To this end, the structure of the door hinge using steel wire is carefully studied, and the principle of the door hinge operation through the steel wire is explained in detail. The door hinge of this embodiment connects the m...

Abstract

The invention relates to a door hinge for a washing machine. The speed for closing a door is adjusted via a spring, the door hinge is simple in action principles, lower in manufacturing unit price and easier to assemble. The door hinge comprises a rotation cam, a support, a reciprocating component, a steel wire, a first fixing pin and a second fixing pin. The rotation cam is rotatively arranged in a door framework. Via the combination of a driving shaft and a rotary framework fixed on a door, the driving shaft rotates along the rotation of the rotary framework. The support is arranged in the door framework and is separated from the rotation cam to fix a spring storing device storing a spring. The reciprocating component is arranged on the outer diameter of the spring storing device and reciprocates along with the spring storing device. The steel wire extends along a hollow part of the spring storing device. Two ends of the steel wire are respectively fixed on the reciprocating component and the rotation cam.

Description

technical field [0001] The invention relates to a door hinge, in particular to a door hinge used in a washing machine which can safely complete the door closing action. Background technique [0002] The washing machine is a device that automatically cleans, rinses, and dries the laundry by relying on the mechanical impact of the washing water after putting the laundry, washing water and an appropriate amount of detergent into the washing tank. The washing machine is composed of a main body of the washing machine including a washing tank and a door for switching the main body. The main body of the washing machine and the door are connected through a door hinge, and one side of the door hinge is combined with the main body of the washing machine and the other side is combined with the door. Door hinges usually use the elasticity of the spring so that the speed of closing the door can be artificially adjusted. If the speed of closing the door is adjusted, it is possible to pr...
