HOME APPLIANCE

BACKGROUND
1. Field

The disclosure relates to a home appliance. More particularly, the disclosure relates to a home appliance including a damping assembly with an improved structure for reducing abrasion, impacts, and noise that are caused by repetitive use of a door.

2. Description of the Related Art

In general, a damping assembly is applied to all kinds of home appliances having a door for opening and closing operations.

There are a left/right hinged door that is opened and closed in a left or right direction with respect to the left or right side of the door, and an up/down hinged door that is opened and closed in an up or down direction with respect to the upper side of the door.

Since the up/down hinged door wears down, receives impacts, or generates noise when it is repetitively closed, the up/down hinged door generally includes a damper for causing the door to be slowly closed from at a predetermined angle.

However, the damper is configured to perform a rotatory motion or a horizontal or vertical translation motion, and accordingly the damper has difficulties in operation conversion and also has a complicated configuration.

The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

When the first lever 120H moves to the second position P2, the damper 130H connected to the first lever 120H and located above the first lever 120H may generate resistance in a direction that is vertical to the movement direction of the first lever 120H.

Details about the structure and operations of the damping assembly 100H with the above-described configuration will be able to be understood sufficiently from the above description, and therefore, overlapping descriptions thereof will be omitted.

FIGS. 26 and 27 show a damping assembly and an operation of the damping assembly, according to a tenth embodiment of the disclosure. Reference numerals not shown in FIGS. 26 and 27 will be able to be understood by referring to FIGS. 1 to 8.

Referring to FIGS. 26 and 27, a damping assembly 100I may be installed in the main body 10.

The damping assembly 100I may include a damping bracket 110I, a first lever 120I disposed in the damping bracket 110I, and a damper 130I connected to the rear end of the first lever 120I and located above the first lever 120I.

The damping bracket 110I may include an accommodating space 112I in which the first lever 120I and the damper 130I are installed.

In the front lower portion of the damping bracket 110I, a first lever installing space 111I in which the first lever 120I is installed to be movable in the front-back direction may open.

The damper 130I connected to the first lever 120I may be disposed behind and above the first lever 120I to move linearly in a direction that is vertical to a movement path of the first lever 120I.

The damper 130I may include a second lever 131I connected to the first lever 120I to be movable vertically, a cylinder 132I connected to the second lever 131I, and a cylinder housing 133I for accommodating the cylinder 132I and installing the cylinder 132I in the damping bracket 110I.

The first lever 120I may be accommodated in the accommodating space 112I of the damping bracket 110I in such a way to be movable in the front-back direction. The first lever 120I may include a contact portion 121I at the front end to be pressed by the pressing portion 38 of the door 11.

The first lever 120I may be connected to a first link 126I and a second link 125I installed on the damping bracket 110I. At the upper ends of the first link 126I and the second link 125I, a first link rotating shaft 126Ia and a second link rotating shaft 125Ia may be disposed. One end of the first link 126I may be fixed at the first link rotating shaft 126Ia, and the other end of the first link 126I may be rotatably installed. One end of the second link 125I may be fixed at the second link rotating shaft 125Ia, and the other end of the second link 125I may be rotatably installed.

The first link 126I may be longer than the second link 125I.

The first lever 120I may include a first first-lever rotation shaft 1311I and a second first-lever rotation shaft 1322I. The first first-lever rotation shaft 1311I of the first lever 120I may be connected to the first link 126I. The second first-lever rotation shaft 1322I of the first lever 120I may be connected to the second link 125I.

Accordingly, when the contact portion 121I is pressed by the door 11, the first lever 120I may move backward, while the first first-lever rotation shaft 1311I and the second first-lever rotation shaft 1322I are rotatably supported by the first link 126I and the second link 125I.

Meanwhile, in the rear portion of the first lever 120I, a first-lever guide surface 127I may be formed to guide the second lever 131I to move vertically simultaneously with a movement of the first lever 120I.

The first-lever guide surface 127I may be connected to the second lever 131I, and guide the second lever 131I to linearly move vertically simultaneously with a movement of the first lever 120I.

The second lever 131I may be accommodated in the cylinder housing 133I to move vertically by the cylinder 132I.

Meanwhile, when the door 11 is not pressed, the first lever 120I may be located at the first position P1, and when the door 11 is pressed, the pressing portion 38 of the door 11 may press the contact portion 121I of the first lever 120I, and then the first lever 120I may move to the second position P2.

When the first lever 120I moves to the second position P2, the second lever 131I of the damper 130I connected to the rear portion of the first lever 120I and located above the first lever 120I may generate resistance in a direction that is vertical to the movement direction of the first lever 120I.

Details about the structure and operations of the damping assembly 100I with the above-described configuration will be able to be understood sufficiently from the above description, and therefore, overlapping descriptions thereof will be omitted.

According to the embodiments of the disclosure, it may be possible to reduce abrasion, impacts, and noise that are caused by repetitive use of the door.

Also, through direct driving of the door apparatus, it may be possible to reduce manufacturing cost with a small number of parts.

Also, by buffering the door when it is closed, it may be possible to reduce impacts and noise, thereby improving a user's convenience and durability.

While the disclosure has been shown and described with reference to various embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure as defined by the appended claims and their equivalents.
