refrigerator

Abstract

The invention provides a refrigerator comprising a refrigerator body and a storage box installed in the refrigerator body. Sliding ways, sliding rods, first rotating shafts arranged on the same side with the sliding rods and first sliding wheels on the outer side wall of the storage box are arranged between the inner side walls of the refrigerator body and the outer side walls of the storage box, wherein the sliding ways and the sliding rods are mutually matched. The sliding rods and the first sliding wheels are matched with the sliding ways so that the storage box can be driven to be pulled frontwards and backwards in the refrigerator body. The outline of each first sliding wheel is arranged to be in a circular truncated cone shape. According to the refrigerator, in the process that the storage box is pushed and pulled along the refrigerator body, under the action of the gravity, the gravity center of the storage box is automatically aligned with the middle position of the sliding ways, the manually exerted action force can be counteracted by reactive force generated by the sliding wheels and the sliding ways and the sliding rods matched with the sliding wheels during push and pull, and the situation that when the storage box is pushed and pulled, the storage box shakes left and right, so that sliding is not smooth is avoided.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a refrigerator. Background technique [0002] As a container that can keep food or other items in a constant low temperature and cold state, a refrigerator has become one of the indispensable household appliances in modern families. Wherein the refrigerator usually includes a refrigerating compartment and a freezing compartment which are arranged separately from each other, and a drawable storage box can be arranged in the refrigerating compartment or the freezing compartment for separately storing food which needs to be preserved at different temperatures. thing. [0003] Usually, a slideway and a slide bar that cooperate with each other are set between the storage box and the box body, and rollers that cooperate with the slideway and / or the slide bar are arranged to facilitate the storage box to be pulled back and forth from the compartment of the refrigerator The track...

AI Technical Summary

Problems solved by technology

However, since the liner that constitutes the refrigerator box needs to be foamed during the manufacturing process, it is difficult to accurately control the size of the side wall of the box after foaming, which deviates from the theoretical size. In this way, the storage box and the side wall of the refrigerator In this case, once the storage box receives force in the left and right directions during the pulling process, it will not run smoothly, and the storage box will be biased in the left and right directions to its adjacent refrigerator. One side wall, so that the storage box is stuck during the pulling process, and the pushing and pulling is not smooth.
