Description

refrigerator

Technical field

The invention relates to a refrigerator, in particular to a refrigerator with a power-assisted slide.

Background technique

The track on which the existing slide slides is a horizontal track, and the storage box runs horizontally and smoothly during the push-pull process, but the front and rear ends of the storage box are respectively fixed by the limit buckle or the interference, so that the storage box is in the box When the middle reaches the innermost and outermost positions, there is no tendency to stop after automatically moving to the maximum position. If the ground is not flat, the movement trend of the storage box will be affected by the ground, and the position of closing or opening the object cannot be stopped.

The refrigerator usually has a certain rear elevation angle when it is installed. If the slide itself is horizontal, the slide will still tilt backwards because the front end of the refrigerator has a low rear end. When the drawer is pulled out, it is decomposed by gravity to break back the force along the direction of the slide. This will cause the drawer to stop at the maximum position when the drawer is pulled out of the pick-and-place item. The drawer will automatically close backward when the hand is released. It is not convenient to pick and place items.

In view of this, it is necessary to improve the existing refrigerator slide to solve the above problems.

The direction in which the segment extends. In the prior art, the slide bar 21 and the slide 30 generally extend in a single horizontal front-rear direction, and in the present invention, the slide guide 21 and the support guide section of the slide 30 have at least one oblique extension 40, thereby Make The support guide section has at least two slopes and at least one bend inflection point.

In the embodiment of the present invention, the oblique extending portion 40 can have two embodiments, and the two embodiments will be described in detail in the following description.

Embodiment 1: As shown in FIG. 4 and in conjunction with FIG. 2 and FIG. 3, at least one oblique extension 40 is disposed on the lower sidewall of the slide bar 21. Specifically, the lower side wall of the slide bar 21 is provided with a smooth portion 24 (which extends in the horizontal direction with a slope of 0) and two obliquely extending portions 40 which are disposed on both sides of the smooth portion 24, and the two oblique portions The extending portions 40 extend from the both ends of the smoothing portion 24 toward the left obliquely upward and the right obliquely upward, respectively. Those skilled in the art will appreciate that the terms "left" and "right", which are used herein to refer to a relative positional relationship, are based on the viewing direction of FIG. The above description for the slide bar 21 can be replaced by "the two oblique extensions 40 respectively from the front end and the rear end of the smooth portion 24, respectively, based on the state when the slide bar 21 is mounted in the case 10 for use. It extends toward the upper front and the upper rear obliquely."

An obliquely extending portion extending from the front end of the smoothing portion 24 toward the front obliquely upward is defined as a first oblique extending portion 41, and a joint of the smoothing portion 24 and the first oblique extending portion 41 is defined as a first inflection point 411; an obliquely extending portion extending from the rear end of the smoothing portion 24 toward the obliquely rearward upper portion is defined as a second obliquely extending portion 42, and a joint of the smoothing portion 24 and the second obliquely extending portion 42 is defined as Two inflection points 421.

Thus, as the storage box 20 is pulled forward, the first roller 22 moves forward along the slide 30 while the second roller 31 moves rearward relative to the inner side wall of the slider 21. When the second roller 31 moves from the smoothing portion 24 past the second inflection point 421, the front end of the storage box 20 will be inclined downward by its own weight, while the second roller 31 starts to move backward along the second oblique extending portion 42. Finally, the storage box 20 automatically reaches the maximum opening and closing position under the action of its own weight, so as to facilitate the picking and placing of articles. When the storage box 20 is pushed backward, the first roller 22 moves rearward along the slide 30 while the second roller 31 moves forward relative to the inner side wall of the slide bar 21. When the second roller 31 moves from the smoothing portion 24 past the first inflection point 411, the front end of the storage box 20 is inclined downward by its own weight, while the second roller 31 starts to be opposite along the lower surface of the first obliquely extending portion 41. Moving forward in the first oblique extension 41, the final storage box 20 will automatically move backwards under self-weight until it is completely closed.
