Below in conjunction with accompanying drawing, describe according to the control method of the refrigerator of the embodiment of the present invention, control system and refrigerator.
Before describing according to the control method of the refrigerator of the embodiment of the present invention, first the refrigerator in connection with 2 pairs of embodiment of the present invention of accompanying drawing is described.
As shown in Figure 2, refrigerator 300 according to an embodiment of the invention, comprising: casing, door body, control system and refrigeration system 320 etc.Wherein, be limited with a chamber in casing, a chamber includes but not limited to refrigerating chamber 311 and refrigerating chamber 312, certainly also can comprise temperature-changing chamber etc.Door body is arranged on casing with chamber between opening and closing.Control system further comprises at least one refrigerated storage temperature sensor 313, at least one cryogenic temperature sensor 314 and controller 315, wherein, at least one refrigerated storage temperature sensor 313 is arranged in refrigerating chamber 311, at least one cryogenic temperature sensor 312 is arranged in refrigerating chamber 312, and controller 315 is connected with refrigeration system 320, at least one refrigerated storage temperature sensor 311 and at least one cryogenic temperature sensor 312 respectively.
After the structure of refrigerator of understanding the embodiment of the present invention, the control method of the refrigerator of the embodiment of the present invention is described in detail.As shown in Figure 1, shown in Fig. 2, the control method of refrigerator according to an embodiment of the invention, comprises the following steps:
Step S101: obtain the Current Temperatures of refrigerating chamber 311 and/or the Current Temperatures of the refrigerating chamber 312 that at least one cryogenic temperature sensor 314 detects that at least one refrigerated storage temperature sensor 313 detects.
That is to say, in the refrigerating chamber 311 of refrigerator, be provided with at least one refrigerated storage temperature sensor 313, to detect in real time the temperature in refrigerating chamber 311.In the refrigerating chamber 312 of refrigerator, be provided with at least one cryogenic temperature sensor 314, to detect in real time the temperature in refrigerating chamber 312.Thereby just can get the Current Temperatures of refrigerating chamber 311, the Current Temperatures of refrigerating chamber 312.
Step S102: whether the difference whether difference that judges the Current Temperatures of refrigerating chamber 311 and the preset temperature of refrigerating chamber 311 is more than or equal to the Current Temperatures of the first predetermined threshold value and/or refrigerating chamber 312 and the preset temperature of refrigerating chamber 312 is more than or equal to the second predetermined threshold value.
Wherein, the preset temperature of the preset temperature of refrigerating chamber 311, refrigerating chamber 312 can write refrigerator by technical staff when refrigerator appears on the scene, or the setting of the preset temperature of the preset temperature of refrigerating chamber 311, refrigerating chamber 312 exists one to set interface, it is not open to user that this sets interface, such as set the preset temperature of refrigerating chamber 311, the button of the preset temperature of refrigerating chamber 312 etc. for user on the display and control panel of refrigerator, user can not change the preset temperature of refrigerating chamber 311, the preset temperature of refrigerating chamber 312.Technical staff can access this setting interface to carry out the preset temperature of refrigerating chamber 311, setting and the modification of the preset temperature of refrigerating chamber 312 by the mode of certain agreement, and the mode of for example, several Macintosh on the aobvious control face of the refrigerator of arranging by technical staff is accessed setting interface.
The preset temperature of refrigerating chamber 311 refers to: the opening of refrigerating chamber 311, break point temperature or with the temperature of the opening of refrigerating chamber 311, break point temperature correlation; for example; when the Current Temperatures of refrigerating chamber 311 is during higher than the preset temperature of refrigerating chamber 311; controlling refrigeration system freezes to refrigerating chamber 311; when the Current Temperatures of refrigerating chamber 311 is during lower than the preset temperature of refrigerating chamber 311, control refrigeration system and stop the refrigeration to refrigerating chamber 311.Or, when the Current Temperatures of refrigerating chamber 311 is higher than the preset temperature of refrigerating chamber 311 and while spending higher than this preset temperature 1 to 2, controlling refrigeration system freezes to refrigerating chamber 311, when the Current Temperatures of refrigerating chamber 311 is lower than the preset temperature of refrigerating chamber 311 and while spending lower than preset temperature 1 to 2, control refrigeration system and stop the refrigeration to refrigerating chamber 311.
Similarly; the preset temperature of refrigerating chamber 312 refers to: the opening of refrigerating chamber 312, break point temperature or with the temperature of the opening of refrigerating chamber 312, break point temperature correlation; for example; when the Current Temperatures of refrigerating chamber 312 is higher than the preset temperature of refrigerating chamber 312 and while spending higher than this preset temperature 1 to 2; controlling refrigeration system freezes to refrigerating chamber 312; when the Current Temperatures of refrigerating chamber 312 is lower than the preset temperature of refrigerating chamber 312 and while spending lower than preset temperature 1 to 2, control refrigeration system and stop the refrigeration to refrigerating chamber 312.
As a concrete example, the preset temperature of refrigerating chamber 311 is but is not limited to: a certain temperature in 2 to 10 degree, the preset temperature of refrigerating chamber 312 is but is not limited to: a certain temperature in-16 to-24 degree.
Step S103: if the difference of the preset temperature of the Current Temperatures of refrigerating chamber 311 and refrigerating chamber 311 is more than or equal to the first predetermined threshold value, automatically control refrigerating chamber 311 and enter fast cold mode of operation, if and/or the difference of the preset temperature of the Current Temperatures of refrigerating chamber 312 and refrigerating chamber 312 is more than or equal to the second predetermined threshold value, automatically controls refrigerating chamber 312 and enter quick-frozen mode of operation.
For example: the difference of the preset temperature of the Current Temperatures of refrigerating chamber 311 and refrigerating chamber 311 is designated as to △ t1, the first predetermined threshold value for but be not limited to 4 degree, therefore, when △ t1 >=4 ℃, automatically control refrigerating chamber 311 and enter fast cold pattern.The cold pattern of speed can be accelerated the cooling rate of refrigerating chamber 311, otherwise, as 4 ℃ of △ t1 <, exit fast cold function.It should be noted that, the mode of operation that fast cold pattern is a kind of routine, all possesses this function in existing a lot of refrigerators, in order to reduce redundancy, how the cold pattern of speed is not moved and is described herein.
That is to say, suppose the interior much awfully hot food of putting into suddenly of refrigerating chamber 311, according to hot transfer principle, temperature in refrigerating chamber 311 will raise rapidly, likely cause more than temperature in refrigerating chamber 311 is increased to rapidly 4 degree higher than the preset temperature of refrigerating chamber 311, therefore,, in order to accelerate to reduce the temperature in refrigerating chamber 311, automatically enter fast cold pattern.
In like manner, for example: the difference of the preset temperature of the Current Temperatures of refrigerating chamber 312 and refrigerating chamber 312 is designated as to △ t2, the second predetermined threshold value for but be not limited to 4 degree, therefore, when △ t2 >=4 ℃, automatically control refrigerating chamber 312 and enter quick-frozen pattern.The cold pattern of speed can be accelerated the cooling rate of refrigerating chamber 312, otherwise, as 4 ℃ of △ t2 <, exit quick-frozen function.It should be noted that, the mode of operation that quick-frozen pattern is a kind of routine, all possesses this function in existing a lot of refrigerators, in order to reduce redundancy, how quick-frozen pattern is not moved and is described herein.
That is to say, suppose the interior much awfully hot food of putting into suddenly of refrigerating chamber 312, according to hot transfer principle, temperature in refrigerating chamber 312 will raise rapidly, likely cause more than temperature in refrigerating chamber 312 is increased to rapidly 4 degree higher than the preset temperature of refrigerating chamber 312, therefore,, in order to accelerate to reduce the temperature in refrigerating chamber 312, automatically enter quick-frozen pattern.
Be understandable that, in the whole space of refrigerating chamber, refrigerating chamber, may there is temperature contrast in zones of different.For example: while putting awfully hot food into refrigerating chamber, the temperature in the region of the periphery of close food may be a lot of higher than the temperature in other region in refrigerating chamber.For example: if the refrigerated storage temperature sensor 313 being arranged in refrigerating chamber 311 is far away apart from food, the temperature that now refrigerated storage temperature sensor 313 detects may be lower, do not reach the condition to refrigerating chamber 311 refrigeration, can not reflect truly the temperature in refrigerating chamber 311.If the duration is longer, owing to refrigerating chamber not being freezed for a long time, and food temperature is higher, causes food spoilage.
Therefore, in one embodiment of the invention, refrigerated storage temperature sensor 313 is a plurality of, and cryogenic temperature sensor 314 is a plurality of, a plurality of refrigerated storage temperature sensors 313 can be arranged in the interior zones of different of refrigerating chamber 311, thereby can all detect the temperature of refrigerating chamber 311 interior zoness of different.In like manner known, a plurality of cryogenic temperature sensors 314 can be arranged in the interior zones of different of refrigerating chamber 312, thereby can all detect the temperature of refrigerating chamber 312 interior zoness of different.
As from the foregoing, if the difference of the maximum temperature in the Current Temperatures of the refrigerating chamber that a plurality of refrigerated storage temperature sensors 313 detect and the preset temperature of refrigerating chamber 311 is more than or equal to the first predetermined threshold value, automatically control refrigerating chamber 311 and enter fast cold mode of operation, if and/or the difference of the preset temperature of the maximum temperature in the Current Temperatures of the refrigerating chamber 312 that detects of a plurality of cryogenic temperature sensor 314 and refrigerating chamber 312 is more than or equal to the second predetermined threshold value, automatically controls refrigerating chamber 312 and enter quick-frozen mode of operation.Maximum temperature in refrigerating chamber 311 can reflect the temperature in refrigerating chamber 311 truly.Maximum temperature in refrigerating chamber 312 can reflect the temperature in refrigerating chamber 312 truly, thereby can guarantee refrigerating chamber 311, the interior temperature of refrigerating chamber 312 can be not too high, prevents food spoilage or thaws, and guarantees the refrigeration of refrigerator.
Further, if judge that the difference of the preset temperature of maximum temperature in the Current Temperatures of the refrigerating chamber 311 that a plurality of refrigerated storage temperature sensors 313 detect and refrigerating chamber 311 is less than the first predetermined threshold value, automatically control refrigerating chamber 311 and exit fast cold mode of operation, if and/or the difference of the preset temperature of the maximum temperature in the Current Temperatures of the refrigerating chamber 312 that detects of a plurality of cryogenic temperature sensor 314 and refrigerating chamber 312 is less than the second predetermined threshold value, automatically controls refrigerating chamber and exit quick-frozen mode of operation.
That is to say, if the highest temperature in the whole region of refrigerating chamber 311 is not very high, there is no need that refrigerating chamber 311 is carried out to speed cold, save energy consumption.Similarly, if the highest temperature in the whole region of refrigerating chamber 312 is not very high, there is no need refrigerating chamber 312 to be carried out to quick-frozen, energy-conservation energy consumption.
Shown in Fig. 2, in one embodiment of the invention, refrigerator 300 also comprises: environment temperature sensor 316 and compensating heater 317, environment temperature sensor 316 is for detection of the temperature of refrigerator 300 environment of living in, compensating heater 317 is for heating refrigerating chamber 311, therefore, the control method of this refrigerator also can comprise:
1, obtain the temperature of refrigerator 300 environment of living in of environment temperature sensor 316 detections;
Temperature and the default environment temperature of refrigerator 300 environment of living in that 2, detect according to environment temperature sensor 316 judge whether that 317 pairs of refrigerating chambers 311 of control and compensation heater heat.For example: if the temperature of refrigerator 300 environment of living in that environment temperature sensor 316 detects lower than the lasting shutdown cooling time of default environment temperature and refrigerating chamber 311 higher than Preset Time, 317 pairs of refrigerating chambers 311 of control and compensation heater heat until refrigerating chamber 311 meets refrigerating chamber refrigeration condition.
Imagine, the winter in the north is colder, as northeast, the temperature in winter is usually less than 0 degree, therefore, if refrigerator for a long time under very low environment temperature (as 0 degree), the temperature in refrigerating chamber 311 is not easy to rise to the preset temperature of above-mentioned refrigerating chamber.Cause like this problem, for example, for the refrigerator of single refrigeration system, may for example, because refrigerating chamber 311 does not reach refrigeration condition (: the temperature in refrigerating chamber 311 is for a long time lower than the starting point temperature of refrigerating chamber) for a long time, therefore, refrigeration system is not worked for a long time, thereby causes the temperature of refrigerating chamber 312 to rise, and loses freezing object, even cause food thawing, the temperature in refrigerating chamber 311 in refrigerating chamber 312 too low all the time, lose the object of refrigeration.
Therefore, for example, when the interior temperature of refrigerating chamber 311 does not reach starting point temperature for a long time, can heat refrigerating chamber 311, thereby can make refrigeration system operation, guarantee the function of refrigerating chamber 312 and the function of refrigerating chamber 311.In above-mentioned example, single refrigeration system refers to: during refrigeration system operation, can, simultaneously to refrigerating chamber 311 and refrigerating chamber 312 refrigeration, can not to refrigerating chamber 312, freeze individually.Certainly, applicable equally for many refrigeration systems.Wherein, many refrigeration systems refer to: can freeze independently to refrigerating chamber 311 and refrigerating chamber 312.
According to the control method of the refrigerator of the embodiment of the present invention, without manual operation, just can automatically make refrigerating chamber, refrigerating chamber enter suitable mode of operation according to the load condition of refrigerator, thus promote refrigerator refrigeration, make consumer more save worry, use the market competitiveness more convenient, lifting refrigerator.
Further embodiment of the present invention provides a kind of refrigerator, as shown in Figure 2, goes back the refrigerator 300 of an embodiment according to the present invention, comprising: casing, door body, control system and refrigeration system 320 etc.Wherein, be limited with a chamber in casing, a chamber includes but not limited to refrigerating chamber 311 and refrigerating chamber 312, certainly also can comprise temperature-changing chamber etc.Door body is arranged on casing with chamber between opening and closing.Control system further comprises at least one refrigerated storage temperature sensor 313, at least one cryogenic temperature sensor 314 and controller 315 (for example single-chip microcomputer), wherein, at least one refrigerated storage temperature sensor 313 is arranged in refrigerating chamber 311, at least one cryogenic temperature sensor 312 is arranged in refrigerating chamber 312, and controller 315 is connected with refrigeration system 320, at least one refrigerated storage temperature sensor 311 and at least one cryogenic temperature sensor 312 respectively.
Below control system is described in detail.Controller is used for: obtain the Current Temperatures of refrigerating chamber 311 and/or the Current Temperatures of the refrigerating chamber 312 that at least one cryogenic temperature sensor 314 detects that at least one refrigerated storage temperature sensor 313 detects, and whether the difference whether difference that judges the Current Temperatures of refrigerating chamber 311 and the preset temperature of refrigerating chamber 311 is more than or equal to the Current Temperatures of the first predetermined threshold value and/or refrigerating chamber 312 and the preset temperature of refrigerating chamber 312 is more than or equal to the second predetermined threshold value, if and the difference of the preset temperature of the Current Temperatures of refrigerating chamber 311 and refrigerating chamber 311 is more than or equal to the first predetermined threshold value, automatically control refrigerating chamber 311 and enter fast cold mode of operation, if and/or the difference of the preset temperature of the Current Temperatures of refrigerating chamber 312 and refrigerating chamber 312 is more than or equal to the second predetermined threshold value, automatically control refrigerating chamber 312 and enter quick-frozen mode of operation.
Specifically, in the refrigerating chamber 311 of refrigerator, be provided with at least one refrigerated storage temperature sensor 313, to detect in real time the temperature in refrigerating chamber 311.In the refrigerating chamber 312 of refrigerator, be provided with at least one cryogenic temperature sensor 314, to detect in real time the temperature in refrigerating chamber 312.Thereby just can get the Current Temperatures of refrigerating chamber 311, the Current Temperatures of refrigerating chamber 312.
The preset temperature of the preset temperature of refrigerating chamber 311, refrigerating chamber 312 can write refrigerator by technical staff when refrigerator appears on the scene, or the setting of the preset temperature of the preset temperature of refrigerating chamber 311, refrigerating chamber 312 exists one to set interface, it is not open to user that this sets interface, such as set the preset temperature of refrigerating chamber 311, the button of the preset temperature of refrigerating chamber 312 etc. for user on the display and control panel of refrigerator, user can not change the preset temperature of refrigerating chamber 311, the preset temperature of refrigerating chamber 312.Technical staff can access this setting interface to carry out the preset temperature of refrigerating chamber 311, setting and the modification of the preset temperature of refrigerating chamber 312 by the mode of certain agreement, and the mode of for example, several Macintosh on the aobvious control face of the refrigerator of arranging by technical staff is accessed setting interface.
The preset temperature of refrigerating chamber 311 refers to: the opening of refrigerating chamber 311, break point temperature or with the temperature of the opening of refrigerating chamber 311, break point temperature correlation; for example; when the Current Temperatures of refrigerating chamber 311 is during higher than the preset temperature of refrigerating chamber 311; controlling refrigeration system freezes to refrigerating chamber 311; when the Current Temperatures of refrigerating chamber 311 is during lower than the preset temperature of refrigerating chamber 311, control refrigeration system and stop the refrigeration to refrigerating chamber 311.Or, when the Current Temperatures of refrigerating chamber 311 is higher than the preset temperature of refrigerating chamber 311 and while spending higher than this preset temperature 1 to 2, controlling refrigeration system freezes to refrigerating chamber 311, when the Current Temperatures of refrigerating chamber 311 is lower than the preset temperature of refrigerating chamber 311 and while spending lower than preset temperature 1 to 2, control refrigeration system and stop the refrigeration to refrigerating chamber 311.
Similarly; the preset temperature of refrigerating chamber 312 refers to: the opening of refrigerating chamber 312, break point temperature or with the temperature of the opening of refrigerating chamber 312, break point temperature correlation; for example; when the Current Temperatures of refrigerating chamber 312 is higher than the preset temperature of refrigerating chamber 312 and while spending higher than this preset temperature 1 to 2; controlling refrigeration system freezes to refrigerating chamber 312; when the Current Temperatures of refrigerating chamber 312 is lower than the preset temperature of refrigerating chamber 312 and while spending lower than preset temperature 1 to 2, control refrigeration system and stop the refrigeration to refrigerating chamber 312.
As a concrete example, the preset temperature of refrigerating chamber 311 is but is not limited to: a certain temperature in 2 to 10 degree, the preset temperature of refrigerating chamber 312 is but is not limited to: a certain temperature in-16 to-24 degree.
For example: the difference of the preset temperature of the Current Temperatures of refrigerating chamber 311 and refrigerating chamber 311 is designated as to △ t1, the first predetermined threshold value for but be not limited to 4 degree, therefore, when △ t1 >=4 ℃, automatically control refrigerating chamber 311 and enter fast cold pattern.The cold pattern of speed can be accelerated the cooling rate of refrigerating chamber 311, otherwise, as 4 ℃ of △ t1 <, exit fast cold function.It should be noted that, the mode of operation that fast cold pattern is a kind of routine, all possesses this function in existing a lot of refrigerators, in order to reduce redundancy, how the cold pattern of speed is not moved and is described herein.
That is to say, suppose the interior much awfully hot food of putting into suddenly of refrigerating chamber 311, according to hot transfer principle, temperature in refrigerating chamber 311 will raise rapidly, likely cause more than temperature in refrigerating chamber 311 is increased to rapidly 4 degree higher than the preset temperature of refrigerating chamber 311, therefore,, in order to accelerate to reduce the temperature in refrigerating chamber 311, automatically enter fast cold pattern.
In like manner, for example: the difference of the preset temperature of the Current Temperatures of refrigerating chamber 312 and refrigerating chamber 312 is designated as to △ t2, the second predetermined threshold value for but be not limited to 4 degree, therefore, when △ t2 >=4 ℃, automatically control refrigerating chamber 312 and enter quick-frozen pattern.The cold pattern of speed can be accelerated the cooling rate of refrigerating chamber 312, otherwise, as 4 ℃ of △ t2 <, exit quick-frozen function.It should be noted that, the mode of operation that quick-frozen pattern is a kind of routine, all possesses this function in existing a lot of refrigerators, in order to reduce redundancy, how quick-frozen pattern is not moved and is described herein.
That is to say, suppose the interior much awfully hot food of putting into suddenly of refrigerating chamber 312, according to hot transfer principle, temperature in refrigerating chamber 312 will raise rapidly, likely cause more than temperature in refrigerating chamber 312 is increased to rapidly 4 degree higher than the preset temperature of refrigerating chamber 312, therefore,, in order to accelerate to reduce the temperature in refrigerating chamber 312, automatically enter quick-frozen pattern.
Be understandable that, in the whole space of refrigerating chamber, refrigerating chamber, may there is temperature contrast in zones of different.For example: while putting awfully hot food into refrigerating chamber, the temperature in the region of the periphery of close food may be a lot of higher than the temperature in other region in refrigerating chamber.For example: if the refrigerated storage temperature sensor 313 being arranged in refrigerating chamber 311 is far away apart from food, the temperature that now refrigerated storage temperature sensor 313 detects may be lower, do not reach the condition to refrigerating chamber 311 refrigeration, can not reflect truly the temperature in refrigerating chamber 311.If the duration is longer, owing to refrigerating chamber not being freezed for a long time, and food temperature is higher, causes food spoilage.
Therefore, in one embodiment of the invention, refrigerated storage temperature sensor 313 is a plurality of, cryogenic temperature sensor 314 is a plurality of, a plurality of refrigerated storage temperature sensors 313 are arranged on a plurality of regions in refrigerating chamber 311, be that a plurality of refrigerated storage temperature sensors 313 can be arranged in the interior zones of different of refrigerating chamber 311, thereby can all detect the temperature of refrigerating chamber 311 interior zoness of different.In like manner known, a plurality of cryogenic temperature sensors 314 are arranged on a plurality of regions in refrigerating chamber 312, and a plurality of cryogenic temperature sensors 314 can be arranged in the interior zones of different of refrigerating chamber 312, thereby can all detect the temperature of refrigerating chamber 312 interior zoness of different.
Advantageously, a plurality of refrigerated storage temperature sensors 313 at least comprise the refrigerated storage temperature sensor 313 that is arranged on refrigerating chamber 311 interior plates and right inside side plate, and a plurality of cryogenic temperature sensors 314 at least comprise the cryogenic temperature sensor that is arranged on refrigerating chamber 312 interior plates and right inside side plate.This be due to, refrigerating chamber 311 interior plates and Right Inboard panel area are acted upon by temperature changes comparatively obvious.In like manner, refrigerating chamber 312 interior plates and Right Inboard panel area are acted upon by temperature changes comparatively obvious.Thereby, be beneficial to the temperature detecting in more accurate refrigerating chamber 311 and refrigerating chamber 312.
As from the foregoing, if the difference of the maximum temperature in the Current Temperatures of the refrigerating chamber that a plurality of refrigerated storage temperature sensors 313 detect and the preset temperature of refrigerating chamber 311 is more than or equal to the first predetermined threshold value, automatically control refrigerating chamber 311 and enter fast cold mode of operation, if and/or the difference of the preset temperature of the maximum temperature in the Current Temperatures of the refrigerating chamber 312 that detects of a plurality of cryogenic temperature sensor 314 and refrigerating chamber 312 is more than or equal to the second predetermined threshold value, automatically controls refrigerating chamber 312 and enter quick-frozen mode of operation.Maximum temperature in refrigerating chamber 311 can reflect the temperature in refrigerating chamber 311 truly.Maximum temperature in refrigerating chamber 312 can reflect the temperature in refrigerating chamber 312 truly, thereby can guarantee refrigerating chamber 311, the interior temperature of refrigerating chamber 312 can be not too high, prevents food spoilage or thaws, and guarantees the refrigeration of refrigerator.
Further, if judge that the difference of the preset temperature of maximum temperature in the Current Temperatures of the refrigerating chamber 311 that a plurality of refrigerated storage temperature sensors 313 detect and refrigerating chamber 311 is less than the first predetermined threshold value, automatically control refrigerating chamber 311 and exit fast cold mode of operation, if and/or the difference of the preset temperature of the maximum temperature in the Current Temperatures of the refrigerating chamber 312 that detects of a plurality of cryogenic temperature sensor 314 and refrigerating chamber 312 is less than the second predetermined threshold value, automatically controls refrigerating chamber and exit quick-frozen mode of operation.
That is to say, if the highest temperature in the whole region of refrigerating chamber 311 is not very high, there is no need that refrigerating chamber 311 is carried out to speed cold, save energy consumption.Similarly, if the highest temperature in the whole region of refrigerating chamber 312 is not very high, there is no need refrigerating chamber 312 to be carried out to quick-frozen, energy-conservation energy consumption.
Shown in Fig. 2, in one embodiment of the invention, control system also comprises: environment temperature sensor 316 and compensating heater 317, environment temperature sensor 316 is for detection of the temperature of refrigerator 300 environment of living in, compensating heater 317 is for heating refrigerating chamber 311, therefore, controller 315 is also for the temperature of obtaining refrigerator 300 environment of living in that environment temperature sensor 316 detects, and temperature and the default environment temperature of refrigerator 300 environment of living in that detect according to environment temperature sensor 316 judge whether that 317 pairs of refrigerating chambers 311 of control and compensation heater heat.For example: if the temperature of refrigerator 300 environment of living in that environment temperature sensor 316 detects lower than the lasting shutdown cooling time of default environment temperature and refrigerating chamber 311 higher than Preset Time, 317 pairs of refrigerating chambers 311 of control and compensation heater heat until refrigerating chamber 311 meets refrigerating chamber refrigeration condition.
Imagine, the winter in the north is colder, as northeast, the temperature in winter is usually less than 0 degree, therefore, if refrigerator for a long time under very low environment temperature (as 0 degree), the temperature in refrigerating chamber 311 is not easy to rise to the preset temperature of above-mentioned refrigerating chamber.Cause like this problem, for example, for the refrigerator of single refrigeration system, may for example, because refrigerating chamber 311 does not reach refrigeration condition (: the temperature in refrigerating chamber 311 is for a long time lower than the starting point temperature of refrigerating chamber) for a long time, therefore, refrigeration system is not worked for a long time, thereby causes the temperature of refrigerating chamber 312 to rise, and loses freezing object, even cause food thawing, the temperature in refrigerating chamber 311 in refrigerating chamber 312 too low all the time, lose the object of refrigeration.
Therefore, for example, when the interior temperature of refrigerating chamber 311 does not reach starting point temperature for a long time, can heat refrigerating chamber 311, thereby can make refrigeration system operation, guarantee the function of refrigerating chamber 312 and the function of refrigerating chamber 311.In above-mentioned example, single refrigeration system refers to: during refrigeration system operation, can, simultaneously to refrigerating chamber 311 and refrigerating chamber 312 refrigeration, can not to refrigerating chamber 312, freeze individually.Certainly, applicable equally for many refrigeration systems.Wherein, many refrigeration systems refer to: can freeze independently to refrigerating chamber 311 and refrigerating chamber 312.
According to the control system of the refrigerator of the embodiment of the present invention, without manual operation, just can automatically make refrigerating chamber, refrigerating chamber enter suitable mode of operation according to the load condition of refrigerator, thus promote refrigerator refrigeration, make consumer more save worry, use the market competitiveness more convenient, lifting refrigerator.
