Background technology
Minimum possible loss when guaranteeing that air flows to described import from the air duct of described door, the outlet of described air duct traditionally are set to when described door is closed and formation relative with described import with respect to described import closely and the closure that roughly seals.
The problem that such refrigeration plant produces is, the door of closing can be owing to manufacturing tolerance changes with respect to the position of body, and also can be owing to for example change for the load of doors such as fluctuating temperature changes in the course of work of refrigeration plant.If described outlet is not set to accurately relative with described import, so because the decline of such skew and air throughput exists pressure to descend at transition point.If air stream is promoted by ventilation blower, keep the required required fan power of air throughput to increase so, and the energy efficiency of described refrigeration plant is had a negative impact.In addition, the decline of pressure impels air to escape from the transition point between air duct and the import at the small opening place, perhaps impels extraneous air to flow into.For the refrigeration plant that has a plurality of storages chamber, this can have a negative impact to each storage chamber thermal release.
Summary of the invention
The objective of the invention is to propose the refrigeration plant of the given type in a kind of front, it utilizes simple means to guarantee that air circulates from the low loss that first air duct enters first import, and any possible motion between door and the body is allowed in described low loss circulation.
Described purpose is realized by a kind of refrigeration plant of body and door that comprises, described body comprises at least one storage chamber and independent evaporator chamber, wherein first import in the face of described door is formed in the wall of described evaporator chamber, and first air duct extends in having the door of outlet, described outlet is positioned at the opposite of first import that is spaced from by the gap, the guide of flow surface extends on the described door from the edge of described first import, and described air duct is shaped as inclined orientation ground and discharges air and flow to described guiding surface.This in fact forms such air stream, and described air stream can and make the still air in described gap mobile without any the described guiding surface in situation lower edge of the vortex of significance degree in basic free of losses just because of wall attachment effect.Because the air throughput of described import can not be less than the air throughput of described air duct when the closed path cocycle of air in described refrigeration plant, therefore the air of discharging from described air duct flows and will be absorbed by described import fully basically.
No matter how flowing of described air duct all still joined with described first import safely in order to ensure the tolerance of the position of described door, described import advantageously has the size bigger than described outlet.If fully utilized the reception capacity of described first input port from the air of described air duct, so in fact do not have air flow through described evaporator chamber first import be not subjected to the described zone of flowing and influencing.
In order further to improve described effect, the guided plate that in first import, has been parallel to described guide of flow surface arrangement.
