Description
Technical field
The present invention relates to MOD technical field, be specifically related to the electronic of a kind of band drainage mechanism
Air door.
Background technology
In wind cooling refrigerator, MOD is used to control the opening and closing in air channel, to regulate ice
The temperature of each room of case.MOD generally comprises pedestal, door-plate and leeboard.But, ice
There is the bigger temperature difference in each room of case, causes usually being formed on MOD condensation water, work as temperature
During less than 0 DEG C, condensation water can build-up ice again.The normal work of MOD is brought by icing phenomenon
Interference: during unlatching, if MOD door-plate is frozen in, MOD will be unable to open；Close
Time, freeze if MOD mouth exists, door-plate will be caused cannot to close tightly, cause a room (cold
Hide room, temperature-changing chamber) supercooling.In prior art, for preventing condensation water from build-uping ice, typically meeting exists
Heater strip is increased, to reduce condensation water and icing phenomenon on the door-plate of MOD.But when adding
During heated filament work, the ice formed can be melted into water, but owing to leeboard is positioned at lower air port
Being formed around doorframe, thawing water cannot be discharged in time, can only remain in formation ponding in storage tank,
When the temperature decreases, ponding can congeal into ice again again.
