Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The control method of a kind of wind cooling refrigerator that the embodiment of the present invention provides is applied to wind cooling refrigerator.Wind cooling refrigerator comprises: refrigerating chamber and refrigerating chamber, be arranged on the evaporimeter in refrigerating chamber, and connect the air channel of refrigerating chamber and refrigerating chamber, be arranged on the air door on air channel.The air inlet of air door is communicated with refrigerating chamber, and the air outlet of air door is communicated with air channel.
Wherein, the temperature of refrigerating chamber generally will lower than subzero 18 DEG C (degree Celsius); The temperature of refrigerating chamber is 5 DEG C of left and right.Certainly, the temperature of refrigerating chamber and refrigerating chamber also can arrange according to actual requirement or experience, and the present embodiment does not limit this.
Evaporimeter operated by rotary motion, in refrigerating chamber, is the main refrigeration plant of wind cooling refrigerator, plays the effect of refrigeration.

It should be noted that, in wind cooling refrigerator, also comprise miscellaneous part, for example, compressor, blower fan etc., the present invention does not limit the parts that comprise in wind cooling refrigerator.
The control method of a kind of wind cooling refrigerator that the embodiment of the present invention provides, as shown in Figure 1, comprises following several step:
S101, by described evaporimeter is heated, to realize defrost processing.
Concrete, the control device of wind cooling refrigerator is determined and need to be carried out, after defrost processing, described evaporimeter being heated to remove the frost on evaporimeter to evaporimeter.Be, evaporimeter is carried out to heat treated, utilize thermal evaporation to remove the frost on evaporimeter.
Further, the control device of wind cooling refrigerator can be according to the running time of wind cooling refrigerator, judges whether evaporimeter to carry out defrost processing.Be and determine whether reach default running time running time of wind cooling refrigerator, if reach default running time the running time of wind cooling refrigerator, determine evaporimeter is carried out to defrost processing.If do not reach default running time the running time of wind cooling refrigerator, determine that wind cooling refrigerator continues normal operation work.
Or the control device of wind cooling refrigerator also can be according to the Current Temperatures of wind cooling refrigerator refrigerating chamber, judges whether evaporimeter to carry out defrost processing.This is that although its temperature can constantly change, its maximum temperature can not exceed certain temperature value because the temperature of refrigerating chamber generally will be lower than subzero 18 DEG C.In the time that the temperature of refrigerating chamber exceedes certain temperature value, the refrigeration that refrigerating chamber is described is poor, make the excess Temperature of refrigerating chamber, namely the refrigeration of evaporimeter is poor, now can think that the refrigerator on evaporimeter is more, the thermal resistance that can increase evaporimeter and air, hinders the heat exchange between evaporimeter and air, thereby affects refrigeration.So whether the control device of wind cooling refrigerator can reach temperature threshold values by the Current Temperatures of determining wind cooling refrigerator refrigerating chamber, if the Current Temperatures of wind cooling refrigerator refrigerating chamber reaches temperature threshold values, determines evaporimeter is carried out to defrost processing.If the Current Temperatures of wind cooling refrigerator refrigerating chamber does not reach temperature threshold values, determine that wind cooling refrigerator continues normal operation work.
It should be noted that, in the embodiment of the present invention, the control device of wind cooling refrigerator also can determine whether evaporimeter needs defrost according to the temperature of other chambers of wind cooling refrigerator, for example, determine whether to need defrost according to the temperature of refrigerating chamber, now, its corresponding temperature threshold values can specifically be set as required.The present invention is to determining whether evaporimeter needs the method for defrost not limit.

Concrete, the control device control door opening of wind cooling refrigerator, the heat producing while making evaporimeter heat diffuses to refrigerating chamber by air door from refrigerating chamber, so that refrigerating chamber is shared the part heat producing when evaporimeter is heated.
It should be noted that, during due to wind cooling refrigerator defrost, can suspend refrigeration, and the blower fan in wind cooling refrigerator quits work, the heat producing when like this evaporimeter heating is to be slowly diffused into refrigerating chamber, and the space of refrigerating chamber is large, temperature relative evaporation actuator temperature is higher, so when the heat producing when evaporimeter is heated is delivered to refrigerating chamber from evaporimeter, very little on the temperature impact of refrigerating chamber.
Further, by on same typhoon cold refrigerator, respectively refrigerating chamber and refrigerating chamber are chosen to three points for measuring temperature, its temperature is tested, contrast the impact that utilizes the control method of the wind cooling refrigerator that the present invention proposes to realize the temperature on refrigerating chamber and refrigerating chamber after evaporimeter defrost, and utilize traditional control method to realize the impact of the temperature that (is control method of the prior art) to refrigerating chamber and refrigerating chamber after evaporimeter defrost, experimental data is as shown in table one, table two.Wherein, table one is for utilizing traditional control method to realize the experimental data of the impact of the temperature on refrigerating chamber and refrigerating chamber after evaporimeter defrost.Table two is for utilizing the control method of the wind cooling refrigerator that the present invention proposes to realize the experimental data of the impact of the temperature on refrigerating chamber and refrigerating chamber after evaporimeter defrost.
Table one
Table two
Find by above-mentioned experimental data contrast, the control method of utilizing the wind cooling refrigerator that the present invention proposes to evaporimeter defrost after, the temperature-averaging of refrigerating chamber has gone up 28.2 DEG C, and after utilizing traditional control method to evaporimeter defrost, the temperature-averaging of refrigerating chamber has gone up 32.1 DEG C.Can find out, the control method of utilizing the wind cooling refrigerator that the present invention proposes to evaporimeter defrost after refrigerating chamber temperature-averaging rise Billy with traditional control method to evaporimeter defrost after the temperature-averaging of refrigerating chamber go up to have declined 3.9 DEG C.The control method of utilizing the wind cooling refrigerator that the present invention proposes to evaporimeter defrost after, temperature of refrigerating chamber has on average gone up 4.1 DEG C, and after utilizing traditional control method to evaporimeter defrost, temperature of refrigerating chamber on average gos up 4.0 DEG C.Can find out, the control method of utilizing the wind cooling refrigerator that the present invention proposes to evaporimeter defrost after the temperature-averaging of refrigerating chamber go up and utilize traditional control method to evaporimeter defrost after the temperature-averaging of refrigerating chamber go up to differ very little, negligible.
Hence one can see that, flows to refrigerating chamber by opening the heat producing when air door makes evaporimeter heat by air channel, reduced the temperature recovery of refrigerating chamber, simultaneously very little on the temperature impact of refrigerating chamber.So, just shorten the time that wind cooling refrigerator refrigerating chamber freezes again, reduced the energy consumption of wind cooling refrigerator.

Optionally, in the time that unlatching parameter is heating-up temperature, opening the pre-conditioned of air door is that heating-up temperature is greater than preset temperature, describedly meet while opening air door pre-conditioned in described unlatching parameter, opening described air door comprises: in the time that definite described heating-up temperature is greater than preset temperature, open described air door, as shown in Figure 4.
That is to say, using heating-up temperature as the parameter of opening air door.In the time that the control device of wind cooling refrigerator starts evaporimeter to heat, start the heating-up temperature of record to evaporimeter heating.Like this, the control device of wind cooling refrigerator can be according to the heating-up temperature to evaporimeter heating, determines whether that the heat diffusion that heating process can be produced is to refrigerating chamber.In the time that heating-up temperature is greater than preset temperature, the heat diffusion that explanation can produce heating process is to refrigerating chamber, in the time that heating-up temperature is not more than preset temperature, the frost on evaporimeter has not been dissolved in explanation, and the heat diffusion that heating process can not be produced is to refrigerating chamber.So the control device of wind cooling refrigerator determines whether to open air door, the heat diffusion that heating process is produced during to refrigerating chamber, need to first determine whether heating-up temperature is greater than preset temperature.
The control method of a kind of wind cooling refrigerator that the embodiment of the present invention provides, by described evaporimeter is heated, to realize defrost processing; Open air door, to make the heat producing when described evaporimeter is heated flow to refrigerating chamber by air channel.Like this, make the temperature of refrigerating chamber compared with Gao Eryan with respect to only eliminating by refrigerating chamber the heat producing when evaporimeter is heated in prior art, the present invention connects the air door on the air channel of refrigerating chamber and refrigerating chamber by unlatching, the space of refrigerating chamber and refrigerating chamber is communicated, allow a part of heat producing when evaporimeter is heated be delivered to refrigerating chamber from refrigerating chamber, be that refrigerating chamber can be shared a part of heat producing when evaporimeter is heated, thereby reduce the temperature recovery of refrigerating chamber, and the temperature recovery of refrigerating chamber is lower, the time that refrigerating chamber freezes is again shorter, and then shorten the time that wind cooling refrigerator refrigerating chamber freezes again, reduce the energy consumption of wind cooling refrigerator.Said method has overcome in prior art in the process because of wind cooling refrigerator defrost, the problem that time is long, wind cooling refrigerator energy consumption increases that the heat producing when evaporimeter is heated makes the temperature rising of refrigerating chamber cause refrigerating chamber again to freeze, realize and shortened the time that wind cooling refrigerator refrigerating chamber freezes again, reduced the object of the energy consumption of wind cooling refrigerator.Further, by obtaining the unlatching parameter relevant to opening described air door, and meet while opening air door pre-conditioned in described unlatching parameter, open described air door, like this can be in the time of the frost of eliminating on evaporimeter, close air door, concentrate evaporimeter is added to thermogenetic heat, eliminate the frost on evaporimeter; In the time that needs are eliminated the heat that evaporimeter heat to time generation, open air door, in ensureing to eliminate the frost efficiency on evaporimeter, realize by refrigerating chamber and share a part of heat that evaporimeter heat to time generation, reduce the temperature recovery of refrigerating chamber, and the temperature recovery of refrigerating chamber is lower, the time that refrigerating chamber freezes is again shorter, and then shorten the time that wind cooling refrigerator refrigerating chamber freezes again, reduce the object of the energy consumption of wind cooling refrigerator.
