Description

Refrigerator

Technical field

The utility model relates to a kind of refrigerator, relates in particular to a kind of refrigerator fruits and vegetables chamber indirect refrigeration structure.

Background technology

The refrigeration modes of wind cooling refrigerator normally by the evaporimeter refrigeration, is assigned to chamber between each difference through ducting system with cold air again, and the air conditioning quantity that control arrives each chamber satisfies the temperature setting of chamber between difference.Cold air arrives each chamber via ducting system generally has dual mode: first kind of mode is directly to leave the air port in ducting system, and cold air directly blows in the chamber; The second way is that ducting system arrives the not direct opening in a chamber, and cold air blows on the coldplate or other cooling structures around the chamber, through this coldplate or the indirect chilling room of cooling structure chamber, makes it reach required design temperature.Wherein, first kind of mode is that direct air-out mode cooling velocity is fast, provides cold big, but in the cooling procedure, an indoor convection current is big, and the food moisture that is stored in a chamber runs off big; The second way is that the indirect type of cooling does not directly blow on the food owing to cold air, and it is few to be kept at indoor food moisture loss, and temperature fluctuation is little, good refreshing effect.

To leafy vegetable, foods such as fruit, the water loss meeting influences fresh-keeping effect, shortens the food holding time.The fruits and vegetables chamber of therefore, placing this group food in the general refrigerator uses the indirect type of cooling can obtain fresh-keeping effect preferably.But relatively directly the air-out type of cooling is slower for type of cooling cooling velocity indirectly, and inhomogeneous cooling is even, and fluctuations in indoor temperature is big; Owing to increased extra cooling structure, dischargeable capacity reduces in the refrigerator simultaneously, and volumetric efficiency reduces; In addition, when indoor because food thermal source or subscriber switch door picked and placeed food, hot outside got into and causes the dewfall phenomenon; The icing phenomenon that local overcooling causes perhaps appears in the refrigerator running.

Therefore, to above-mentioned technical problem, be necessary to provide a kind of structure improved refrigerator that has, to overcome above-mentioned defective.
