Detailed description of the invention
Present embodiments provide the defrosting control method of a kind of wind cooling refrigerator and wind cooling refrigerator.Fig. 1 is the schematic diagram of wind cooling refrigerator according to an embodiment of the invention.This wind cooling refrigerator 10 can comprise casing 100, is limited with room and air channel 30 between multiple storing in casing 100.Between multiple storing, room can have different temperature ranges, for providing different storage ambient.Such as can comprise refrigerator room 110 and freezing compartment 120 in room between multiple storing, in addition, between storing, room can also increase flexibly and arranges quick-frozen room and/or ice-making compartment.
Air channel 200, for generation of the air-flow of indoor circulation between storing, is provided with blower fan 210210 and the cooling chamber 230 for arranging cooler 220 in inside, air channel 200.Upon actuation, can freeze to the air-flow through it, the moisture in air-flow can frosting on cooler 220 for cooler 220.Cooler 220, as the low-temperature receiver of refrigerator 10, can use the evaporimeter of coolant circulating system.Air-flow after carrying out heat exchange with cooler 40 enters refrigerator room 110 and freezing compartment 120, to complete refrigeration by air-supply passage respectively through the air outlet of refrigerator room 110 and freezing compartment 120.Air-flow puts back to the upstream of cooling chamber 230 by return air channel from the return air inlet of refrigerator room 110 and freezing compartment 120, realize kind of refrigeration cycle.
In order to realize carrying out defrost to cooler 220, adjacent cooler 220 can also be provided with defrosting device.This defrosting device can be use the various realization such as electrical heating wire, infrared heating device to heat cooler 220 surface, to melt the frosting on cooler 220 surface.The wind cooling refrigerator 10 of the present embodiment, in order to carry out accurately defrosting control to above cooler 220, is also provided with the parts such as image capturing device, frosting indicating card 310, background board 320.
Fig. 2 is the schematic elevational view of cooler 220 in wind cooling refrigerator 10 according to an embodiment of the invention, and Fig. 3 is the left side schematic elevational view of cooler 220 in wind cooling refrigerator 10 according to an embodiment of the invention; Fig. 4 is the schematic right-side view of cooler 220 in wind cooling refrigerator 10 according to an embodiment of the invention.Can find out that cooler 220 can use finned evaporator by Fig. 2 to Fig. 4, comprise coiled pipe and be set in the fin on coiled pipe.This cooler 220 can be fixed by the gripper shoe 240 of both sides.In further embodiments, cooler 220 also can adopt other forms of heat-exchanger rig.
Image capturing device (not shown) can be arranged in cooling chamber 230, is configured to take cooler 220.Figure filming apparatus can be configured with light source, to provide shooting illumination in the cooling chamber 230 closed.
One or more frosting indicating card 310, be arranged at be positioned at image capturing device coverage in cooler 220 part on, and its color configuration becomes and shows a sharp contrast with the color of cooler 220 and white.Each frosting indicating card 310 comprises the colour code post that multiple parallel interval is arranged, and the colour code post color of each frosting indicating card 310 is set to difference.Show the situation that each frosting indicating card 310 is provided with two colour code posts in the drawings, in actual use can the number of flexible configuration colour code post.The color that colour code post can select redness, green, yellow etc. and color and the white of cooler 220 to show a sharp contrast.The color of adjacent colour code post arranges and is preferably set to difference, and frosting indicating card 310 can adopt the material identical with cooler 220 to make, and directly abuts on cooler 220, to ensure and cooler 220 frosting simultaneously and defrost.
In order to improve the identity of image further, wind cooling refrigerator 10 also comprises: one or more background board 320, correspondingly with frosting indicating card 310 to arrange, as the background of frosting indicating card 310 in the shooting image of image capturing device, the color configuration one-tenth of background board 320 all shows a sharp contrast with the color of frosting indicating card 310, the color of cooler 220, white.When frosting indicating card 310 is set to redness, green, background board 320 can be set to yellow.
Defrosting device, the cooler 220 that reclines is arranged, and a kind of optional position is the bottom being arranged at cooler 220.Defrosting device can be determined at the image of the shooting according to image capturing device and start after frosting indicating card 310 is covered by frost, to carry out defrost to cooler 220, and determine at the image of the shooting according to image capturing device and close after frosting indicating card 310 all appears, stop carrying out defrost to cooler 220.Image due to the shooting of image capturing device directly reflects cooler 220 surface condition, can carry out defrosting control targetedly, avoids the heat exchange efficiency that frosting affects cooler 220 on the one hand, reduces the electric energy that defrost consumes on the other hand as far as possible.
