When the door 202 is lifted, the lower clip 40 fixed at the bottom of the door 202 is lifted, and the lower clip 40 drives the shaft sleeve 30 to lift upwards. At this time, the first guide portion 31 moves upward to cooperate with the first rotation portion 21, lift the first rotation portion 21, and drive the first rotation portion 21 to rotate. Since the shaft sleeve 30 is circumferentially fixed to the hinge shaft 10, when the first guide 31 and the first rotation part 21 are relatively rotated, it means that the height adjusting member 20 is rotated relative to the hinge shaft 10.
Referring to fig. 7 and 8, the first guide portion 31 has a first guide inclined surface 31a facing the first rotating portion 21 in the height direction, and the first rotating portion 21 has a first rotating inclined surface 21a disposed opposite to the first guide inclined surface 31 a. When the first guide portion 31 moves upward, the first guide inclined surface 31a abuts the first rotation inclined surface 21a and drives the first rotation portion 21 to slide along the inclined surface extending direction.

The second driving mechanism D2 drives the height adjuster 20 to rotate as follows:
referring to fig. 5 and 6, the hinge shaft 10 has a center hole 10b, and a second guide portion 13 is disposed on a hole wall of the center hole 10 b. Referring to fig. 7, the height adjuster 20 has a rod body 22, the rod body 22 is adapted to be inserted into the central hole 10b, and a second rotation portion 23 is provided on an outer circumferential wall of the rod body 22. The second guide portion 13 and the second rotating portion 23 are provided to face each other in the height direction, and form the second drive mechanism D2.
When the door 202 is lifted and lowered, the height adjusting member 20 is lowered to follow the lower edge card 40 of the door. At this time, the second rotating portion 23 moves downward to cooperate with the second guiding portion 13, so that the second guiding portion 13 drives the second rotating portion 23 to rotate. When the second guiding part 13 and the second rotating part 23 rotate relatively, it means that the height adjusting member 20 rotates relative to the hinge shaft 10.
In this embodiment, the second guide portion 13 has a second guide inclined surface 13a facing the second rotation portion 23 in the height direction, and the second rotation portion 23 has a second rotation inclined surface 23a disposed opposite to the second guide inclined surface 13 a. When the second rotation portion 23 moves downward, the second guiding inclined surface 13a abuts against the second rotation inclined surface 23a and drives the second rotation portion 23 to slide along the inclined surface extending direction.
With continued reference to fig. 6, a slot 14 is formed between two adjacent second guiding portions 13, and the second guiding portions 13 are adapted to guide the second rotating portion 23 to rotatably fall into the slot 14. The groove 14 enables circumferential limitation of the height adjustment member 20. That is, when the door 202 is not lifted, the second rotary part 23 is restricted in the slot 14, thereby preventing the relative rotation between the hinge shaft 10 and the height adjuster 20 during the normal use of the electric home appliance.
When the door 202 is lifted and the height adjusting member 20 is lifted a predetermined distance along with the door 202 in the height direction, the second rotation portion 23 is disengaged from the slot 14. At this time, the first guide 31 provided in the bushing 30 can drive the first rotation part 21 provided in the height adjuster 20 to rotate, so that the height adjuster 20 and the hinge shaft 10 rotate relative to each other, thereby changing the height of the height adjuster 20.
As described above, in the hinge unit 100 of the present embodiment, the height adjuster 20 can be automatically rotated during the process of lifting the door 202; the height adjuster 20 can also automatically rotate during the fall of the door 202. The height at which the door 202 is located is automatically changed by the rotation of the height adjusting member 20, thereby achieving the adjustment of the relative position between the height adjusting member 20 and the hinge shaft 10.
In the process, the height adjusting mechanism does not need to be screwed by using a tool, so that the height adjusting mode of the door 202 is relatively simple, and the height of the door of the household appliance can be adjusted quickly and conveniently.
In addition, the present embodiment uses slopes oppositely disposed in the height direction to achieve relative rotation of the height adjusting member 20 and the hinge shaft 10. The inclined planes are arranged on the height adjusting piece 20, the hinge shaft 10 and the shaft sleeve 30, the structure is relatively simple, and the improvement can be carried out on the basis of the prior art; meanwhile, the height adjusting member 20 has good reliability and is not easy to be damaged.
In this embodiment, the first driving mechanism D1 and the second driving mechanism D2 drive the height adjusting member 20 to rotate in the same direction. During the process that the door 202 is lifted and falls, the first driving mechanism D1 and the second driving mechanism D2 drive the height adjusting member 20 to rotate by 60 ° together.
Specifically, the first driving mechanism D1 drives the height adjusting member 20 to rotate through the first guiding inclined surface 31a and the first rotating inclined surface 21a, and the second driving mechanism D2 drives the height adjusting member 20 to rotate through the second guiding inclined surface 13a and the second rotating inclined surface 23 a.
In another modification, the first driving mechanism D1 can drive the height adjuster 20 to rotate only by providing a slope on one of the first guide portion 31 and the first rotating portion 21. Similarly, the second driving mechanism D2 can drive the height adjuster 20 to rotate only by providing a slope on one of the second guide portion 13 and the second rotating portion 23. The implementation of the technical scheme is not influenced.
Further, the above-described slope may not be provided to achieve the rotation of the height adjuster 20. For example, a torsion spring is provided on the height adjusting member 20, and when the lower clip 40 lifts the height adjusting member 20 to a predetermined distance during the process of lifting the door 202, the torsion spring drives the height adjusting member 20 to rotate, so as to adjust the height of the door 202.
In this case, the driving mechanism D does not need to be divided into the first driving mechanism D1 and the second driving mechanism D2. During the lifting of the door 202, the rotation of the height adjuster 20 is completed, for example, 60 °, so that the first and second adapter surfaces 10a, 20a are engaged.
With reference to fig. 4, the lower clip 40 is sleeved outside the shaft sleeve 30, and a first limiting portion 41 is disposed on an inner circumferential surface of the lower clip, and the first limiting portion 41 is located above the height adjusting member 20. Therefore, the height adjuster 20 is retained between the first retaining portion 41 and the first guide portion 31 of the boss.
When the position of the height adjusting member 20 is raised or lowered with respect to the hinge shaft 10, the position of the first position-limiting portion 41 is also raised or lowered, that is, the position of the lower side clip 40 is raised or lowered, thereby achieving the raising or lowering of the door 202.
Referring to fig. 3, 4 and 9, the hinge unit 100 further includes a central shaft 50, and the central shaft 50 is inserted through the height adjuster 20 in a height direction and fixed to the hinge shaft 10 in the height direction. The top of the central shaft 50 is provided with a second limiting part 51, and the second limiting part 51 can limit the lifting height of the height adjusting part 20.
Specifically, one axial end of the central shaft 50 is inserted into the central hole 10b, and is limited in the central hole 10b along the height direction. The second limiting portion 51 is disposed at the other axial end of the central shaft 50, and a distance between the second limiting portion 51 and the top surface of the height adjusting member 20 is a maximum distance that the height adjusting member 20 can rise. By limiting the lifting height of the height-adjusting member 20, it is possible to prevent the door 202 from being damaged by being lifted too much.
In this embodiment, a coil spring 52 is further sleeved outside the central shaft 50, one end of the coil spring 52 abuts against the second limiting portion 51, and the other end abuts against the height adjusting member 20. That is, the coil spring 52 is compressed in the height direction between the second stopper portion 51 and the height adjusting member 20.
When the door 202 is lifted, the height adjusting member 20 moves upward and the coil spring 52 is compressed, thereby enabling the operator to have a better feel during the lifting of the door 202.
Referring to fig. 1, the present technical solution further provides a household appliance 200, including a main body 201 and a door 202 connected to the main body 201, wherein the household appliance 200 further includes the hinge unit 100 described above.
