A kind of air-cooled compressor refrigeration refrigerating box, control method include the following steps:
Step 1, when case inner sensor perceives temperature in refrigerating chamber higher than setting value, press is started to work, evaporator
Start to freeze, blower runs at high speed.
Step 2, when case inner sensor perception temperature in refrigerating chamber reaches setting value, press is shut down, and evaporator stops system
Cold, natural defrost starts: blower continuous running, and unboiled water flows into water receiving ware on evaporator, and the water in water receiving ware persistently steams
Hair.
Step 3, when evaporator sensor detects that evaporator surface temperature reaches 3-5 DEG C, blower stops operating at this time.
Compared with prior art, the beneficial effects of the present invention are: at low cost, only need to increase water receiving ware in air duct bottom is
Can, without being redesigned to product other component；Highly-safe, defrost uses nature defrost, is different from conventional electricity and adds
Thermal cream reduces the danger of kindling and electric shock in case；Feasibility is high, easy to accomplish on product, and operability is very high, simple easy
Row.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
In figure: 1- cabinet, 2- refrigerating chamber, 3- case inner sensor, 4- return air inlet, 5- press, 6- press storehouse, the air duct 7-, 8-
Evaporator, 9- evaporator sensor, 10- blower, 11- air outlet, 12- water receiving ware.
Specific embodiment
Technical solution of the present invention is described in more detail With reference to embodiment.
The refrigerating box referring to Fig. 1, a kind of air-cooled compressor freezes, including cabinet 1 and refrigerating chamber 2, the refrigerating chamber 2 are placed in
The inside of cabinet 1, the bottom at 1 back side of cabinet are equipped with press storehouse 6, fixed press 5 in press storehouse 6；The back side of cabinet 1 and refrigerating chamber
Air duct 7, fixed evaporator 8 in air duct 7 are equipped between 2, evaporator 8 is equipped with evaporator sensor 9, and evaporator sensor 9 is used
In monitoring 8 surface temperature of evaporator；The upper and lower part of the refrigerating chamber 2 is respectively equipped with air outlet 11 and return air inlet 4, air outlet
11 and return air inlet 4 be connected to air duct 7, case inner sensor 3 is equipped with inside refrigerating chamber 2, case inner sensor 3 is for monitoring refrigerating chamber
Temperature in 2；The bottom in the air duct 7 is equipped with water receiving ware 12, and water receiving ware 12 is arranged on 6 top of press storehouse but does not communicate therewith, institute
The top for stating air duct 7 is equipped with blower 10, and 10 position of blower is corresponding with air outlet 11.
The water receiving ware 12 is made of aluminum material, and good heat conductivity facilitates the evaporation of moisture in water receiving ware 12, to cold
