[0006] Furthermore, a third axis is formed on the outer hinge at a position between the first axis and the second axis, which is aligned with the extension direction of the second axis.

[0007] Furthermore, a fourth axis and a fifth axis are formed at the two ends of the inner hinge along its length, the extension direction of the fourth axis being consistent with the extension direction of the first axis, and the extension direction of the fifth axis being consistent with the extension direction of the second axis.

[0008] Furthermore, a first hole is formed on the inner hinge at a position opposite to the third shaft for the third shaft to be installed therein. Through the cooperation of the third shaft and the first hole, a first rotating pair is formed.

[0009] Furthermore, a second hole is formed at one end of the movable hinge seat to cooperate with the fourth shaft, and the movable hinge seat and the inner hinge form a second rotating pair through the cooperation of the fourth shaft and the second hole.

[0010] Furthermore, a first waist-shaped groove is formed on the movable hinge seat at one side of the second hole, and a first sliding pair is formed by the cooperation of the first shaft and the first waist-shaped groove.

[0011] Furthermore, a third hole is formed on the fixed hinge seat at a position opposite to the second shaft, thereby forming a third rotating pair through the cooperation of the second shaft and the third hole.

[0012] Furthermore, a second waist-shaped groove is formed on the fixed hinge seat at one side of the third hole, and a second sliding pair is formed by the cooperation between the fifth shaft and the second waist-shaped groove.

[0013] The present invention has the following beneficial effects: The washing machine of the present invention, through the door hinge assembly of three axes and two sliders, can make the rotation center located outside the door when the door is opened, so that the side of the door does not need to make an avoidance structure, and can be connected to the side of the front door panel at a distance of O.

[0019] The invention will now be further described with reference to the accompanying drawings.

[0020] The present invention relates to a washing machine equipped with a three-axis, two-slider door hinge assembly, comprising a door body 5 and a front door panel 6. The three-axis, two-slider door hinge assembly includes an outer hinge 2, an inner hinge 3, a movable hinge seat 1 mounted on the door body 5, and a fixed hinge seat 4 mounted on the front door panel 6. A first axis 20 and a second axis 21 are respectively formed at both ends along the length direction of the outer hinge 2, wherein the first axis 20 and the second axis 21 extend in opposite directions. A third axis 22 is formed on the outer hinge 2 at a position between the first axis 20 and the second axis 21, consistent with the extending direction of the second axis 21.

[0021] The inner hinge 3 has a fourth shaft 30 and a fifth shaft 31 formed at its two ends along its length. The fourth shaft 30 extends in the same direction as the first shaft 20, and the fifth shaft 31 extends in the same direction as the second shaft 21. A first hole 32 is formed on the inner hinge 3 at a position opposite to the third shaft 22, for the third shaft 22 to be installed therein. The first rotating pair is formed by the cooperation between the third shaft 22 and the first hole 32.

[0022] One end of the movable hinge seat 1 is formed with a second hole 10 that mates with the fourth shaft 30. The movable hinge seat 1 and the inner hinge 3 form a second rotating pair through the engagement of the fourth shaft 30 with the second hole 10.

[0023] A first waist-shaped groove 11 is formed on the movable hinge seat 1 at one side of the second hole 10. The first sliding pair is formed by the cooperation between the first shaft 20 and the first waist-shaped groove 11.

[0024] A third hole 40 is formed on the fixed hinge seat 4 at a position opposite to the second shaft 21. The third rotating pair is formed by the cooperation between the second shaft 21 and the third hole 40.

[0025] A second waist-shaped groove 41 is formed on the fixed hinge seat 4 at one side of the third hole 40. The second sliding pair is formed by the cooperation between the fifth shaft 31 and the second waist-shaped groove 41.

[0026] In the washing machine of this invention, equipped with a three-axis, two-slider door hinge assembly, the movement trajectory of the movable hinge seat 1 driving the door 5 to open does not interfere with the front door panel 6, and the center of rotation is not inside the door 5. Therefore, the front door panel does not need to make any clearance. The washing machine of this invention, through its three-axis, two-slider door hinge assembly, allows the center of rotation to be located outside the door when the door is opened, eliminating the need for clearance structures on the side of the door, thus enabling it to connect with the side of the front door panel at a distance O.

[0027] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be considered within the scope of protection of the present invention.
