Example 1
In the use of current refrigerator, when the fridge load that the ring temperature is great or the gear is lower brings is great, can lead to the long-time air-out of cold-stored air outlet, because the air-out temperature that current refrigerator was cold-stored is less than the zero degree, can lead to air outlet department temperature to be less than the zero degree, lower air-out temperature and longer air-out time can lead to the air outlet phenomenon of freezing to appear. In the temperature control mode of the related technology, the temperature of the refrigerating box is controlled by a refrigerating sensor, and the refrigerating outlet air temperature is not required, so the icing condition can occur.
To solve the above problem, according to an aspect of an embodiment of the present application, there is provided an embodiment of a method for controlling a temperature, as shown in fig. 1, the method including the steps of:

And S2, heating in the refrigerating air duct according to the first air outlet temperature so as to control the temperature of the air outlet within a preset temperature interval, wherein the preset temperature interval is used for preventing icing.
In step S2, there are two cooling modes:
one is as follows: and under the condition that the first air outlet temperature t is lower than a first preset threshold value t0, refrigerating in a heating and refrigerating mode to control the temperature of the air outlet within a preset temperature interval. The method specifically comprises the following steps of S21-S25:
and step S21, controlling the heater to heat according to the initial power P0 (namely the initial power of the refrigerating outlet air heater).
And S22, detecting the second outlet air temperature of the refrigerating outlet again.
Then, the power of the heater is controlled according to the relationship between the second outlet air temperature and the preset temperature interval (such as the interval [0,3 ]) as follows:
and step S23, under the condition that the second outlet air temperature is lower than the lower limit value of the preset temperature interval, improving the power of the heater on the basis of the current power according to a first preset proportion (such as 5%).
And step S24, reducing the power of the heater according to a second preset proportion (for example, 5%) on the basis of the current power under the condition that the second outlet air temperature is higher than the upper limit value of the preset temperature interval.
And S25, keeping the power of the heater unchanged under the condition that the second outlet air temperature is within the preset temperature interval.
The second is that: and under the condition that the first air outlet temperature is not lower than a first preset threshold value t0, refrigerating by adopting a cold-warm alternating refrigerating mode to control the temperature of the air outlet within a preset temperature interval, wherein the cold-warm alternating refrigerating mode is used for indicating that a heater in the refrigerating air duct is intermittently in an on state. The method specifically comprises the following steps S21-S24:
and S21, refrigerating by adopting a cold refrigerating mode, stopping the refrigerator after the refrigerating time reaches a first time length t1 (namely the time of a cold refrigerating period), and detecting the third air outlet temperature of the cold storage air outlet again under the condition that the stopping time reaches a third time length t3 (namely the time for balancing the temperature in the refrigerator in an alternate refrigerating period, if the cold refrigerating period is finished, cold food can transfer cold to the air outlet, and the air outlet temperature sensor indicates the temperature of nearby food at the moment), wherein the cold refrigerating mode is used for indicating that a heater in a cold storage air channel is always in a closed state, namely a normal refrigerating mode, the air outlet temperature is lower, and the refrigerating efficiency is higher.
And S22, refrigerating in a warm refrigerating mode, stopping after the refrigerating time reaches a second time t2 (namely the warm refrigerating cycle time), and detecting the fourth outlet air temperature of the refrigerating air outlet again under the condition that the stopping time reaches a third time t 3.
And then, controlling the power of the heater according to the third outlet air temperature and the fourth outlet air temperature in the following mode:
and step S23, increasing the refrigerating time of the heating and refrigerating mode according to a third preset proportion under the condition that the third air outlet temperature is less than a second preset threshold Ta (the upper limit of the air outlet temperature in the heating and refrigerating cycle is used for preventing the refrigerating efficiency of the refrigerating and refrigerating from being reduced for one thing), and the temperature difference between the fourth air outlet temperature and the third air outlet temperature is less than a third preset threshold Tb (a critical value parameter for judging whether the icing is changed or not).

In the use of refrigerator, if the gear is crossed low or the load is great, can make cold-stored long-time cold wind that blows, lead to near the air outlet temperature lower, lead to cold-stored air outlet department food to freeze. Through the steps, the first outlet air temperature of the refrigerating outlet of the refrigerating equipment is detected; heating is carried out in cold-stored wind channel according to first air-out temperature to with the temperature control of air outlet in predetermineeing the temperature interval, predetermine the temperature interval and be the temperature interval that is used for preventing to freeze, can solve the technical problem that freezing appears in the cold-stored air outlet among the correlation technique.
Example 2
In the technical scheme of the application, a heater is added at the initial place of a refrigerating air channel (such as the middle of a pipeline and the edge of the pipeline, namely a refrigerating air door) to control the refrigerating air outlet temperature, a temperature sensor is added at the refrigerating air outlet and is combined with the heater to control the air outlet temperature and the air outlet time, so that the refrigerating air outlet is prevented from being frozen, and the freshness of food is increased; in consideration of the problem that the refrigerating time is too long when the scheme is used, the scheme for keeping the refrigerating efficiency under the condition of no freezing is provided for ensuring the refrigerating efficiency of the refrigerating box. As an alternative example, the following detailed description is provided to further describe the technical solution of the present application in conjunction with the following specific embodiments:
in the operation of the air-cooled frostless refrigerator, most of the air-cooled frostless refrigerator belongs to a single evaporator, a refrigerating system and a refrigerating chamber are directly refrigerated by cold energy provided by the evaporator, although the temperature is raised to a certain extent after passing through a far air duct path, the temperature is far lower than 0 ℃, under certain working conditions, if the refrigerating gear is adjusted to 2 ℃, under the condition of high load environment temperature, the single operation time of refrigerating and refrigerating is long, and the food near a refrigerating air outlet is frozen due to the temperature of a cold air outlet. The application provides a prevent frozen scheme in cold-stored air outlet department can guarantee the fresh-keeping effect of food.
The freezing of the refrigerating chamber is caused by the fact that the air outlet temperature of the refrigerating air outlet is too low and the air is blown directly for a long time, when air is dispersed into the refrigerator body, the temperature is heated through heat exchange with air in the refrigerator body, the freezing condition occurs at the air outlet, the temperature of the air outlet is lower and does not rise, the temperature of the air outlet is generally below-10 ℃, and the freezing condition can occur after long-time air outlet.
Therefore, the improved place of the air conditioner is determined based on two characteristics of low temperature and long time, and the heater is added at the initial air outlet, namely the refrigeration air door, so that the air outlet temperature is higher than zero; considering that the low outlet air temperature can cause the reduction of the refrigeration efficiency and the overlong refrigeration time, a section of original refrigeration (namely, a heater is not switched on) and a section of warm refrigeration (a heater is switched on) are used for refrigeration, the temperature t0 can be used for judgment, the efficiency is enough when the temperature is low, the refrigeration cannot be performed when the temperature is high, and the refrigeration and heating are alternately performed. Referring to fig. 2:
and S21, when the refrigerating chamber has a refrigerating requirement, refrigerating the refrigerating chamber in a warm refrigerating mode. And judging whether the current temperature t is lower than the temperature t0, if so, executing a step S22, otherwise, executing a step S23.
And S22, achieving the refrigerating and cooling requirements in a heating and cooling mode.
The condition that food freezes appears at the refrigerated air outlet is that the food at the air outlet freezes because the local temperature is lower than 0 ℃ for a long time when the air at the super-cooled air outlet is blown to a place for a long time. In this application scheme, cold-stored refrigeration preferentially adopts the warm refrigeration mode to give the walk-in refrigeration, even make the air outlet temperature be higher than 0 ℃ at the heater of using in cold-stored wind channel installation, as shown in fig. 3:
in step S221, the heater initial power is set to P0.
Step S222, the heater power is controlled in a feedback mode through a refrigerated air outlet sensor T0 (the real-time temperature of a refrigerated air outlet), namely the heater power is increased by one gear when the temperature of the air outlet sensor T0 is lower than 0 ℃, the heater power is reduced by one gear when the temperature of the air outlet sensor T0 is higher than Tc (the upper limit of the air outlet temperature when the temperature of the air outlet sensor T0 is used for controlling the heating and refrigerating mode), the power difference of each gear is 0.05 times, the first gear is 1.05P0, the second gear is 1.10P0, the air outlet temperature is kept between 0 ℃ and T0 < Tc, the air outlet temperature is kept between 0 ℃ and is not lower than 0 ℃, and the maximum refrigerating efficiency can be guaranteed under the condition that ice does not freeze.
And step S23, achieving the refrigerating and cooling requirements in a cooling and heating alternating refrigerating mode.
If the refrigerating time in the heating and refrigerating mode is longer, which represents that the heating and refrigerating efficiency is insufficient under the high-load working condition, the two refrigerating modes of the refrigerating and heating refrigerating mode are alternately and circularly refrigerated. Judging the time of the cold and the warm: the air outlet is provided with a sensor, a balance time period is provided after each cooling and heating time period in the cooling and heating alternation is finished, and the finished time is regarded as the temperature at the air outlet. This is used to adjust the time ratio of cold cooling and warm cooling. As shown in fig. 4:
step S231, firstly, performing the cold cooling mode, performing a certain shutdown period T3 after the cooling period T1 is finished, and recording the temperature of the refrigerated air outlet after the period T3 is finished as T1 (the temperature of the refrigerated air outlet sensor after the shutdown period T3 is finished, which is used to represent the temperature level of the air outlet after the cooling is finished), and may also be used to represent the temperature of the food near the air outlet after the cooling period is finished. And then, performing a heating and cooling cycle, performing a shutdown cycle T3 after the heating and cooling cycle T2 is finished, and recording the temperature of the refrigerating air outlet after the cycle T3 is finished as T2 (the temperature of the refrigerating air outlet sensor after the shutdown time T3 of the heating and cooling cycle is finished is used for representing the temperature level of the air outlet after the heating and cooling are finished), and also can be used for representing the temperature of food near the air outlet after the heating and cooling cycle is finished.
In step S232, the temperature T1 < Ta is lower to represent the icing condition, T2-T1= [ delta ] T < Tb represents that the temperature difference is poor before and after the cold-making cold-warm refrigeration, the temperature difference represents that the ice is not removed in the warm-cold cycle, the warm-cold cycle duration T3 is prolonged until the condition T1 < Ta is met, T2-T1= [ delta ] T > Tb, T1 < Ta represents the ice, and T2-T1= [ delta ] T > Tb is removed after the warm-cold cycle is finished. If T1 > Ta indicates that no icing occurs after the end of the cooling cycle, the heating and cooling cycle can be reduced or eliminated.
