Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
With reference to the schematic flow sheet that Fig. 1, Fig. 1 are refrigerator temperature-controlled process one embodiment of the present invention; As shown in Figure 1, the present embodiment refrigerator temperature-controlled process comprises the following steps:
Step S10, under refrigerator conventional freezing pattern, obtain the temperature value of refrigerator inside at interval of preset time period.
Refrigerator, owing to wanting permanent chilled food, prevents food spoilage, generally can run with conventional freezing mode constant.And after opening refrigerator or being placed into more food, the temperature of refrigerator inside just has rise, by detecting refrigerator internal temperature in the present embodiment, judging the whether opened refrigerator of refrigerator or being placed into more food.Wherein, preset time period can be interval 1S, 2s, also can be many seconds or 1 minute, can sets itself according to actual needs.
Step S20, judge current detection temperature value T1 with whether be greater than variations in temperature threshold value apart from the temperature profile value detected in current preset time period; If so, then step S21 is performed; If not, then step S22 is performed.
Be understandable that, when refrigerator do not have opened or do not put food into time, during with the mode operation that routine is cold, temperature can be more constant, the temperature value T1 of current detection with when being greater than variations in temperature threshold value apart from the temperature profile value detected in current preset time period, then representing that refrigerator temperature has and raises change, now, may be opened refrigerator or be placed into more food, cause the rise of refrigerator internal temperature.
Wherein, temperature profile value can be the upper limit or the lower limit of the normal temperature value of refrigerator under normal freeze and undulating value thereof in certain hour section.
In one embodiment, described temperature profile value comprises the difference apart from the lowest temperature angle value detected in current preset time period.Basically identical apart from the temperature run under the lowest temperature angle value detected in current preset time period and refrigerator conventional freezing pattern, and then the difference calculated between Current Temperatures and this lowest temperature angle value, can judge whether refrigerator has according to the size of this difference to rise again more greatly, if rise again within the scope of temperature normal variation, then continue to keep conventional freezing mode operation, exceed normal variation scope if risen again, then control refrigerator admission velocity module.
Or in another embodiment, described temperature profile value comprises the mean value apart from each temperature value detected in current preset time period.Refrigerator is under conventional freezing pattern, temperature has fluctuation unavoidably, in regular hour section, this temperature fluctuation is that some medium temperature points change up and down within this time period, this medium temperature point is exactly the mean value of each temperature value, show that refrigerator may put into food in limited time when refrigerator internal temperature exceedes the upper of mean value like this, need to open frozen mode.
Step S21, control compressor operate with the first preset speed, enter quick-frozen pattern to make described refrigerator;
This first preset speed is the maximum operational speed of compressor, can certainly be the speed close with compressor maximum (top) speed.The maximum operational speed of such as compressor is 3000 revs/min, then can time compressor with 3000 revs/min of constant operations, also can be run with the speed between 2800-3000 rev/min.
Step S22, described refrigerator is kept to run conventional freezing pattern;
When the temperature value T1 of current detection is with when being less than or equal to variations in temperature threshold value apart from the temperature profile value detected in current preset time period, show that present mode of operation meets the temperature requirements of refrigerator inside, without the need to opening quick-frozen pattern.
Step S30, under quick-frozen pattern, when the running status of described refrigerator reaches the prerequisite exiting described quick-frozen pattern, control described compressor to operate with the second preset speed, make described refrigerator recover conventional freezing pattern, described second preset speed is less than described first preset speed.
This second preset speed can be zero velocity, and namely compressor shuts down, and this second preset speed also can be compressor with a relatively low operate at constant speed, such as 1000 revs/min.Wherein, refrigerator exits the prerequisite of quick-frozen pattern can be according to the quick-frozen time or according to refrigerator temperature.

Or in another embodiment, described step S30 comprises:
Step S3b1, under quick-frozen pattern, judge whether the duration tc that refrigerator enters quick-frozen pattern is greater than preset time t 1; If so, then step S3b11 is performed; If not, then step S3b12 is performed.
Described step S3b11, control described compressor with described second preset speed running, make described refrigerator recover conventional freezing pattern.
Described step S3b12, described refrigerator is kept to run conventional freezing pattern.
The present embodiment is under quick-frozen pattern, and time refrigerator being entered to quick-frozen pattern carries out timing.When described refrigerator enter quick-frozen pattern duration, tc was greater than preset time t 1 time, then can ensure after showing elapsed time t1 that the temperature of refrigerator inside has dropped to the temperature of demand under conventional freezing pattern, without the need to lowering the temperature again.Now, described compressor can be controlled with described second preset speed running, make described refrigerator recover conventional freezing pattern.Preset time t 1 can artificially be arranged as required, such as, can be set to 48 hours, can certainly be set to other times.
The inventive method, by under refrigerator conventional freezing pattern, obtains the temperature value of refrigerator inside at interval of preset time period; When the temperature value T1 of current detection is with when being greater than variations in temperature threshold value apart from the temperature profile value detected in current preset time period, then controls compressor and operate with the first preset speed, enter quick-frozen pattern to make described refrigerator; Under quick-frozen pattern, when the running status of described refrigerator reaches the prerequisite exiting described quick-frozen pattern, control described compressor to operate with the second preset speed, make described refrigerator recover conventional freezing pattern, described second preset speed is less than described first preset speed, thus, present invention achieves refrigerator and automatically can enter or exit quick-frozen pattern according to the change of temperature, without the need to manual operation, very convenient, and electric energy can be saved and extend compressor service life.
