Quantitative dispensing device and refrigerator with same

Abstract

The present invention provides a rationing device. The rationing device comprises a material storage portion, a material discharging portion and a sleeved covering portion; a material storage cavity for accommodating materials is defined in the material storage portion; a material discharging cavity is defined in the material discharging portion; the material discharging portion is provided with at least one feeding opening and a discharging opening which is located at the bottom of the material discharging portion; the materials in the material storage cavity can be allowed to flow into the material discharging cavity through the at least one feeding opening and flow out through the discharging opening; at least a part of the inner wall of the sleeved covering portion is sleeved with the inner side of the material discharging portion so that the material discharging cavity and the material storage cavity can be separated from each other selectively, wherein the inner wall of the sleeved covering portion is located along the material discharging portion; and the sleeved covering portion is configured to move upwards or move downwards relative to the material discharging portion along at least a part of the inner wall of the material discharging portion in a controlled manner, so that the sleeved covering portion can be switched between an opened position where the at least one feeding opening is opened and a closed position where the at least feeding opening is closed, and is selectively maintained at the opened position or the closed position. With the rationing device adopted, the rationing of the materials can be realized, and outward scatter of remaining materials which occurs after a user takes the materials can be prevented.

Description

technical field [0001] The invention relates to quantitative distribution and taking of materials, in particular to a quantitative distribution device and a refrigerator with the quantitative distribution device. Background technique [0002] In daily life, people often need to store food for a long time, especially the storage of granular solid food has environmental requirements such as temperature and humidity. For example, grains, flour, etc. can be stored in a dry, low-temperature environment for a long time without insects and deterioration, and refrigeration and freezing devices (such as refrigerators, freezers, etc.) can meet the low temperature conditions for grain storage. [0003] With the improvement of people's living standards, the refrigerating and freezing device in the prior art can be equipped with a grain distribution device for storing grain. However, these grain dispensing devices are either relatively complex in structure and cumbersome in operation, o...
