Problems solved by technology

This kind of hinge not only has a single structure, but also during the opening process of the door body, the water chestnut part formed between the horizontal side of the door body front panel where the door body is close to the hinge and the side perpendicular to the horizontal side will move out to the outside. The edge exceeds the vertical plane where the side wall of the box is located. This situation is not suitable for installation on a built-in refrigerator or a refrigerator with a small gap between the box and the wall. This hinge design makes the door of the refrigerator limited opening angle

Embodiment 1

[0031] Such as figure 1 As shown, the present invention provides a hinge assembly, which is installed between the body 1 and the door body 2. In this embodiment, taking a double-door refrigerator as an example, the hinge assembly 3 is described in detail, wherein the body 1 refers to the refrigerator The refrigerator is placed close to the obstacle 4, and the obstacle 4 can be a cabinet when it is embedded and installed or a wall when it is set against the wall.

[0032] Such as figure 2 As shown, the hinge assembly 3 includes a hinge seat 5 fixed on the body 1 , and the hinge seat 5 is used to support the entire hinge assembly 3 . The hinge base 5 is composed of a vertical plate 5a and a horizontal plate 5b. The vertical plate 5a and the horizontal plate 5b are integrally bent and formed by metal plates, and can also be fixedly connected by welding. The vertical plate 5a is fixed on the body 1 by fasteners such as screws, and the horizontal plate 5b is parallel to the bott...

Embodiment 2

[0052] The difference from Embodiment 1 is that in this embodiment, the first hinge arm 8 is preferably arranged above the horizontal plate 5b, and the second hinge arm 9 is arranged below the horizontal plate 5b. The top of the third hinge shaft 11 is fixedly connected with the door body 2 , the middle is rotatably connected with the first hinge arm 6 , and the bottom is fixedly connected with the slider 12 , and the slider 12 slides in the driving groove 10 .

[0053] The third hinge shaft 11 is divided into upper, middle and lower sections, the cross section of the upper section 11a is preferably square, and a square shaft hole is correspondingly arranged on the bottom surface of the door body 2, and the top of the upper section 11a of the third hinge shaft 11 is inserted into the shaft Fixed connection in the hole. The cross-section of the middle section 11c is circular, and is rotatably connected with the first hinge shaft 6. The cross-section of the lower section 11b is ...

Embodiment 3

[0055] The present invention also provides an appliance, such as figure 1 As shown, the appliance can be a household appliance including a washing machine, a dishwasher, a refrigerator, and a freezer. The household appliance includes a body 1 and a door 2, and a hinge assembly 3 is installed between the body 1 and the door 2. The door Two groups of hinge assemblies 3 are installed on one side of 2, and the centers of gravity of the two groups of hinge assemblies 3 coincide to ensure that the door body 2 is opened and closed smoothly. The appliance can also be furniture with a door body, such as various cabinets, bookcases, wardrobes, writing desks, office desks and the like.

Abstract

The invention relates to a hinge assembly and an instrument with the hinge assembly. The hinge assembly comprises a hinge seat fixed on a body, a first hinge shaft and a second hinge shaft are fixed on the hinge seat, the first hinge shaft and the second hinge shaft are rotationally connected with a first hinge arm and a second hinge arm respectively, and a driving groove is formed in the second hinge arm; the hinge assembly further comprises a third hinge shaft, the third hinge shaft is fixedly connected with a door body, the third hinge shaft is in sliding connection with the driving grooveto form a sliding pair, the third hinge shaft is rotationally connected with a first hinge arm to form a rotating pair, and the third hinge shaft slides in the driving groove and rotates around the first hinge shaft and the second hinge shaft to the driving force of the door body to enable the door body to generate displacement in the horizontal plane. The hinge assembly is simple in structure; and the door body does not interfere with an obstacle on one side in the opening process, so that the door body is opened and closed more conveniently, the function that appliances such as household appliances and furniture can be freely embedded can be achieved, and convenience is brought to a user to install and use.

Description

technical field [0001] The invention relates to a hinge assembly and an appliance equipped with the hinge assembly. Background technique [0002] With the gradual improvement of living standards, users have higher and higher requirements for household appliances such as washing machines, dishwashers, refrigerators, and freezers. Like the most commonly used refrigerators in daily life, the traditional refrigerator doors are all arranged in a single-axis structure that rotates around a fixed rotating shaft. This kind of hinge not only has a single structure, but also during the opening process of the door body, the water chestnut part formed between the horizontal side of the plane where the door body front panel of the door body is close to the hinge and the side perpendicular to the horizontal side will move out to the outside. The edge exceeds the vertical plane where the side wall of the box is located. This situation is not suitable for installation on a built-in refrige...
