Further, for accelerating the circulating cold air speed between refrigeration air channel and temperature-changing chamber, refrigeration air channel and refrigerating chamber, when opening the first air door and the 3rd air door when temperature-changing chamber being freezed by refrigeration air channel, can open and be located in refrigeration air channel and the contiguous refrigeration blower fan that refrigerates the air outlet place in air channel, so that acceleration circulating cold air, reach the object of the rapid cooling of temperature of temperature-changing chamber, improve the refrigerating efficiency of temperature-changing chamber.
Further, in above-mentioned example, in temperature-changing chamber process of refrigerastion, also comprise:
Step S504; when the Current Temperatures of temperature-changing chamber is during lower than the shutdown temperature of temperature-changing chamber; close the first air door, the 3rd air door and refrigeration fan so that refrigeration air channel stops, to temperature-changing chamber refrigeration, it should be noted that, shutdown temperature should be not higher than the design temperature of temperature-changing chamber.
In conjunction with Fig. 5, further, the temperature-controlled process of the refrigerator of the embodiment of the present invention also comprises the steps:
Step S505, if the design temperature of temperature-changing chamber lower than the design temperature of refrigerating chamber, is closed the first air door and the 3rd air door, and detects the Current Temperatures of temperature-changing chamber.The design temperature of temperature-changing chamber and the design temperature of refrigerating chamber are the pre-set temperature of user, as user expects the temperature of temperature-changing chamber, maintain-10 ℃ up and down, design temperature can be adjusted to-10 ℃.When the design temperature of temperature-changing chamber is during lower than the design temperature of refrigerating chamber, known, freeze to temperature-changing chamber in the refrigeration air channel of passing through by above-described embodiment mode, because the temperature of the temperature-changing chamber temperature by refrigerating chamber determines, can not be lower than the temperature of refrigerating chamber, therefore, now need by freezing air channel, temperature-changing chamber to be freezed, close all the time the first air door and the 3rd air door.
Step S506, when the Current Temperatures of temperature-changing chamber is during higher than the turn-on temperature of temperature-changing chamber, opens the second air door and the 4th air door temperature-changing chamber is freezed by freezing air channel.In other words, the design temperature of temperature-changing chamber is lower than the design temperature of refrigerating chamber, and the turn-on temperature (starting point temperature) at the Current Temperatures of temperature-changing chamber higher than temperature-changing chamber, by opening the second air door and the 4th air door makes freezing air channel be communicated with temperature-changing chamber, cold air in refrigerating chamber can enter temperature-changing chamber temperature-changing chamber is freezed, because the common temperature of refrigerating chamber is lower, that the temperature that therefore can guarantee refrigerating chamber is down to is temperature required (lower than the temperature of user's expectation of refrigerating chamber design temperature).Particularly, freezing air channel is communicated with temperature-changing chamber, by freezing air channel, by the cold air in refrigerating chamber, the second air inlet by temperature-changing chamber is blown into temperature-changing chamber, cold air turns back in cold air channel in alternating temperature indoor circulation the second return air inlet by temperature-changing chamber, cold air constantly circulates thus, shown in Figure 4, freezing air channel and temperature-changing chamber, circulating cold air direction between freezing air channel and refrigerating chamber is as the direction of arrow in Fig. 4, the temperature of temperature-changing chamber changes with the temperature of refrigerating chamber, the Current Temperatures of temperature-changing chamber can maintain between temperature with cold chamber identical or design temperature and the design temperature of refrigerating chamber in refrigerating chamber.
Thus, temperature-changing chamber can be used as temperature-changing chamber or refrigerating chamber is used, particularly, circulating cold air can be carried out to realize the refrigeration to refrigerating chamber with refrigerating chamber in freezing air channel, and can be at temperature-changing chamber design temperature during lower than the design temperature of refrigerating chamber, by controlling the second air door and the 4th door opening, make temperature-changing chamber and freezing air channel be communicated with to realize the circulating cold air of freezing air channel and temperature-changing chamber, reach the object of freezing air channel to temperature-changing chamber refrigeration.Can to refrigerating chamber and temperature-changing chamber, freeze by freezing air channel simultaneously, also can be individually to refrigerating chamber or refrigerating chamber refrigeration.The Current Temperatures of temperature-changing chamber can be controlled at thus to the identical or temperature of Current Temperatures with refrigerating chamber between the Current Temperatures of refrigerating chamber and the Current Temperatures of refrigerating chamber, especially when refrigerating chamber insufficient space, temperature-changing chamber can be used as refrigerating chamber, further improve the practicality of refrigerator.And the temperature control precision of this control method is high, the range of temperature of temperature-changing chamber is wide.
Further, for accelerating the circulating cold air speed between freezing air channel and temperature-changing chamber, freezing air channel and refrigerating chamber, when opening the second air door and the 4th air door when temperature-changing chamber being freezed by described freezing air channel, can open and be located in freezing air channel and the freezing blower fan at the air outlet place in contiguous freezing air channel, so that acceleration circulating cold air, reach the object of the rapid cooling of temperature of temperature-changing chamber, improve the refrigerating efficiency of temperature-changing chamber.
Further, in this example, in temperature-changing chamber process of refrigerastion, also comprise:
Step S507, when the Current Temperatures of temperature-changing chamber is during lower than the shutdown temperature of described temperature-changing chamber, closes the second air door and the 4th air door to stop the refrigeration to temperature-changing chamber.
It should be noted that, Current Temperatures is the temperature that sensor detects, for example, in temperature-changing chamber, be provided with temperature sensor, for detection of the Current Temperatures of temperature-changing chamber.Turn-on temperature is starting point temperature; shutdown temperature is break point temperature; take temperature-changing chamber as example, and generally, user is that under ideal state, user expects the temperature that temperature-changing chamber maintains to the design temperature of temperature-changing chamber; but; the temperature of temperature-changing chamber will fluctuate at design temperature, and its unsteady upper limit maximum of points is starting point temperature, reaches refrigeration requirement; its unsteady lower limit maximum point is break point temperature, does not need refrigeration.
According to embodiments of the invention, the alternating temperature amplitude of temperature-changing chamber wide (can alternating temperature to minimum be that the temperature of refrigerating chamber is identical, also temperature-changeable is between the temperature of refrigerating chamber and the temperature of refrigerating chamber, also temperature-changeable is extremely higher than temperature of refrigerating chamber), can be according to the actual requirements, using temperature-changing chamber as refrigerating chamber, refrigerating chamber or temperature-changing chamber use, and improves the serviceability of refrigerator, be user-friendly to.And the temperature control precision of the method is high, temperature regulates efficiency high.
Referring to Fig. 6, in another embodiment of the present invention, the temperature-controlled process of refrigerator comprises the steps:
Step S601, the Current Temperatures Tm of detection institute temperature-changing chamber.
Step S602, judges that whether the shutdown temperature Tmt of temperature-changing chamber and the difference of Current Temperatures Tm are greater than or equal to the first difference temperature △ T1.
Step S603, if it is detects the environment temperature Th of refrigerator environment of living in, and judges that whether environment temperature Th is less than or equal to default environment temperature T1.
Step S604, if it is controls temperature compensation heater and with the first preassigned pattern (Mode-1), temperature-changing chamber is heated.
Step S605, moves with the second preassigned pattern (Mode-2) otherwise control temperature compensation heater.
In this example, the first difference temperature and default environment temperature all have experience value to determine.Default environment temperature is relevant to environment temperature, can specifically set as the case may be, for example for winter indoor temperature generally below 20 ℃, therefore predetermined temperature can be made as 20 ℃, and summer the north indoor temperature conventionally between 28 ℃ to 32 ℃, therefore, preset temperature can be made as between 28 ℃ to 32 ℃.And the first difference temperature can be set to 2 ℃.Certainly embodiments of the invention are not limited to this, for the first difference temperature, to the temperature detecting precision of refrigerator, the refrigerating efficiencies of the refrigeration plant of refrigerator etc. are relevant.
According to the temperature-controlled process of the refrigerator of the embodiment of the present invention, the shutdown temperature of temperature-changing chamber is set when higher, as using temperature-changing chamber when refrigerating chamber is used, the design temperature of temperature-changing chamber will be higher, conventionally on 0 ℃, thereby the shutdown temperature of temperature-changing chamber also uprises (shutdown temperature is the temperature of descending temperature value point most that temperature-changing chamber fluctuates in process at design temperature) accordingly, now, the temperature of temperature-changing chamber is not easy to reach the design temperature of temperature-changing chamber, or temperature is accurate not, and between the Current Temperatures of temperature-changing chamber and design temperature, there is larger difference, by temperature compensation heater, temperature-changing chamber is carried out the heating of corresponding modes, can make the temperature of temperature-changing chamber reach rapidly the temperature of relative ideal, close to the design temperature of temperature-changing chamber, thus, make temperature-changing chamber when design temperature is higher, temperature is controlled more accurate, reach rapidly ideal temperature, temperature fluctuation range is little, promote the practicality of refrigerator.And by control module to comparison and correlation between the design temperature of the Current Temperatures of temperature-changing chamber, temperature-changing chamber, the first difference temperature, environment temperature and default environment temperature, through determining the time that temperature compensation heater reply temperature-changing chamber carries out temperature-compensating that determines, thereby effectively and exactly control the temperature of temperature-changing chamber, make the temperature fluctuation range of temperature-changing chamber little, be suitable for the preservation of food, and then promote the practicality of refrigerator.
In above-mentioned example, the heat time that temperature compensation heater moved with the first preassigned pattern higher than temperature compensation heater with the heat time of the first preassigned pattern operation.When the design temperature Tmt of temperature-changing chamber is higher, and when between the Current Temperatures Tm of temperature-changing chamber and the design temperature Tmt of temperature-changing chamber, the temperature difference is larger, when environment temperature Th is less than default environment temperature T1 simultaneously, temperature compensation heater need to be opened the longer time, so that the temperature of temperature-changing chamber reaches design temperature.Otherwise the temperature compensation heater volume heating short period just can be controlled temperature-changing chamber and reach design temperature.
In conjunction with Fig. 6, the temperature-controlled process of the refrigerator of the embodiment of the present invention, further comprising the steps of:
Step S606, if the difference of the shutdown temperature Tmt of temperature-changing chamber and Current Temperatures Tm lower than the first difference temperature △ T1, judges that whether the design temperature Tms of temperature-changing chamber is higher than the first predetermined temperature.In one embodiment of the invention, this first predetermined temperature is for example 0 ℃, easily understand, if the design temperature Tms of temperature-changing chamber is less than 0 ℃, temperature-changing chamber is generally used for refrigerating chamber and uses, and like this, does not just need temperature compensation heater to carry out temperature-compensating, because just needing the temperature of temperature-changing chamber lower (approaching with freezer temperature).
Step S607, if it is judges whether the difference of the design temperature Tms of temperature-changing chamber and the design temperature Tds of refrigerating chamber is less than the second difference temperature △ T2.In one embodiment of the invention, this first predetermined temperature is for example 0 ℃, easily understand, if the design temperature Tms of temperature-changing chamber is higher than 0 ℃, temperature-changing chamber is generally used for refrigerating chamber and uses, and the temperature of refrigerating chamber is too low, the temperature of temperature-changing chamber will be affected, the temperature that hinders temperature-changing chamber raises, and therefore, now needs temperature compensation heater to heat temperature-changing chamber.
Step S608, if it is controls temperature compensation heater and moves with the second preassigned pattern.Be heat time of temperature compensation heater can not be too short can not be long.
Step S609, otherwise judge whether the difference of the design temperature Tms of temperature-changing chamber and the design temperature Tds of refrigerating chamber is less than the 3rd difference temperature △ T3.
Step S610, if it is controls temperature compensation heater and moves with the 3rd preassigned pattern (Mode-3).
Step S611, moves with the first preassigned pattern otherwise control temperature compensation heater.
In this example, the heat time that the heat time that temperature compensation heater moves with the 3rd preassigned pattern is moved with the first preassigned pattern at temperature compensation heater and temperature compensation heater are between the heat time with the second preassigned pattern operation.
It should be noted that, the first difference temperature is less than the second difference temperature, the second difference temperature and is less than the 3rd difference temperature and the first difference temperature to the three difference temperature all higher than zero degree, and the first difference temperature to the three difference temperature and default environment temperature all have experience value to determine.Default environment temperature is relevant to environment temperature, can specifically set as the case may be, for example for winter indoor temperature generally below 20 ℃, therefore predetermined temperature can be made as 20 ℃, and summer the north indoor temperature conventionally between 28 ℃ to 32 ℃, therefore, preset temperature can be made as between 28 ℃ to 32 ℃.And the first to the 3rd difference temperature can must be set to respectively 2 ℃, 3 ℃ and 4 ℃.Certainly embodiments of the invention are not limited to this, for the first to the 3rd difference temperature, to the temperature detecting precision of refrigerator, the refrigerating efficiencies of the refrigeration plant of refrigerator etc. are relevant.
According to the temperature-controlled process of the refrigerator of the embodiment of the present invention, when the design temperature of temperature-changing chamber is higher while using (be generally used for refrigerating chamber), by control module, can accurately controlling temperature compensation heater, with different patterns, temperature-changing chamber to be carried out to fine tune temperature whole, make the temperature of temperature-changing chamber can promptly reach ideal temperature upper and lower (design temperature), have advantages of that control accuracy is high, thereby be beneficial to the preservation of food in temperature-changing chamber, improve the practicality of refrigerator.
