Suspended refrigerator with bottom door

Abstract

The invention discloses a hopper door hanging refrigerator, on the insulation can, there is a suspended and fixed device; the door of the refrigerator is set at the bottom of the insulation can; the door of the refrigerator connects with automatically lifting hydraulic device upper and lower which consists of speed-adjusting motor, oil cylinder connecting with variable displacement hydraulic pump, oil piston-rod, oil cylinder is fixed up on the insulation can, oil piston-rod connects with the door of the refrigerator; Shelve of the goods is fixed up above the door of the refrigerator; the door of the refrigerator drives the shelve move upper and lower along oil piston-rod under the control of the lifting device. The suspended and fixed device includes mounting card and hanging parts; mounting hole is set on the wall of the insulation can; hanging parts includes hook fixed up on the mounting card and the hooker connects with insulation can through mounting hole, compression spring on the hook is set between mounting card and wall of the insulation can. When it is used, it can move upper and lower automatically, calmly, credible and non-noiseful along with opening the opper door and closing the shelve of the goods.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a hanging refrigerator. Background technique [0002] There are various types of refrigerators sold on the market, such as upright refrigerators, cabinet refrigerators with left and right doors, and freezers with top doors, etc. Although there are many types of these refrigerators, when in use, according to their type The differences in size, capacity and layout all require a large area of ​​indoor space, especially for residents or businesses with tight living or business areas. For another example, during the traditional festivals, every household's refrigerators are full of food, even so, there is still a lot of food left over to store, therefore, some families have multiple refrigerators or freezers, which need to occupy more Large interior area. [0003] In order to solve the problem that refrigerators or freezers occupy a large amount of ground, the patent announcement number is CN249178...

AI Technical Summary

Problems solved by technology

Because what the lifting structure in this refrigerator adopts is the combined structure of worm gear pair and cable wheel, its weak point is: (1) the lifting mechanism in this refrigerator passes through the casing, destroys the sealing performance of refrigerator; (2) ) During the lifting process of the refrigerator, there will inevitably be friction between the relevant parts of the lifting mechanism, so the refrigerator will vibrate during the lifting process, which cannot guarantee a reliable and stable completion of the lifting process. At the same time, some noise

Its disadvantages are: the overall geometric size of the refrigerator and its suspension height will be restricted by ergonomics. Therefore, the capacity of the refrigerator cannot meet the needs of the market, or it cannot be compatible with existing buildings due to the limitation of the suspension height. The facade walls are reasonably matched, which limits the use of the site

[0004] In summary, at present, in addition to solving the problem that a refrigerator or an electric freezer occupies a large area, it is imperative to develop a refrigerator that is easy to use, does not vibrate, is stable, reliable, and has no noise during the lifting process. A hanging refrigerator or freezer with a new structure that is conveniently hung on the facade wall of any place
