[0036] Example 1

[0037] During the use of existing refrigerators, when the ambient temperature is high or the gear is low, the refrigerator load is high, which will cause the refrigerated air outlet to discharge air for a long time. Since the air outlet temperature of the existing refrigerator is lower than zero degrees, the temperature at the air outlet will be lower than zero degrees. The low air outlet temperature and long air outlet time will cause ice to form at the air outlet. The temperature control method of the related art uses the refrigeration sensor to control the temperature of the refrigerator, and does not have any requirements for the refrigerated air outlet temperature, so ice will appear.

[0038] To solve the above problems, according to one aspect of the embodiments of the present application, an embodiment of a temperature control method is provided, such as Figure 1 As shown, the method comprises the following steps:

[0039] Step S1, detecting a first air outlet temperature of a refrigeration air outlet of a refrigeration device.

[0040] Optionally, the warm cooling mode can be used for cooling first. When the cooling time using the warm cooling mode reaches a preset time (equivalent to reaching a certain stable state), the first air outlet temperature of the refrigerated air outlet is collected. The warm cooling mode is used to indicate that the heater in the refrigerated air duct is always in the on state, thereby making the air outlet temperature greater than 0°C in the refrigerated cooling mode.

[0041] Step S2, heating is performed in the refrigeration air duct according to the first air outlet temperature to control the temperature of the air outlet within a preset temperature range, and the preset temperature range is a temperature range for preventing freezing.

[0042] There are two cooling modes in step S2:

[0043] One is: when the first air outlet temperature t is lower than the first preset threshold value t0, the warm cooling mode is used for cooling to control the temperature of the air outlet within the preset temperature range. Specifically, steps S21 to S25 are included:

[0044] Step S21, controlling the heater to heat according to the initial power P0 (ie, the initial power of the refrigerated air outlet heater).

[0045] Step S22, re-detecting the second air outlet temperature of the refrigerated air outlet.

[0046] Afterwards, the power of the heater is controlled according to the relationship between the second air outlet temperature and the preset temperature range (such as the range [0, 3]) in the following manner:

[0047] Step S23, when the second air outlet temperature is lower than the lower limit of the preset temperature range, the power of the heater is increased according to a first preset ratio (such as 5%) based on the current power.

[0048] Step S24, when the second air outlet temperature is higher than the upper limit of the preset temperature range, the power of the heater is reduced according to a second preset ratio (such as 5%) based on the current power.

[0049] Step S25, when the second air outlet temperature is within the preset temperature range, the power of the heater is kept unchanged.

[0050] The second is: when the first air outlet temperature is not lower than the first preset threshold value t0, the alternating cooling and heating refrigeration mode is used for refrigeration to control the temperature of the air outlet within the preset temperature range, wherein the alternating cooling and heating refrigeration mode is used to indicate that the heater in the refrigeration air duct is intermittently turned on. Specifically, it includes steps S21-S24:

[0051] Step S21, adopt the cold refrigeration mode for refrigeration, shut down after the refrigeration time reaches the first time t1 (i.e. the cold refrigeration cycle time), re-detect the third air outlet temperature of the refrigerated air outlet when the shutdown time reaches the third time t3 (i.e. the time used to balance the temperature in the box during the alternating refrigeration cycle. After the cold refrigeration cycle ends, the colder food will transfer cold air to the air outlet. At this time, the air outlet temperature sensor indicates the temperature of nearby food). The cold refrigeration mode is used to indicate that the heater in the refrigeration air duct is always in the off state, that is, the normal refrigeration mode, the air outlet temperature is lower, and the refrigeration efficiency is higher.

[0052] Step S22, adopt the warm cooling mode for cooling, shut down after the cooling time reaches the second time t2 (i.e., the warm cooling cycle time), and re-detect the fourth air outlet temperature of the refrigerated air outlet when the shutdown time reaches the third time t3.

[0053] Afterwards, the power of the heater is controlled according to the third air outlet temperature and the fourth air outlet temperature in the following manner:

[0054] Step S23, when the third air outlet temperature is less than the second preset threshold value Ta (the upper limit of the air outlet temperature in the warm cooling cycle, used to prevent the refrigeration efficiency of the cold storage refrigeration from being reduced blindly), and the temperature difference between the fourth air outlet temperature and the third air outlet temperature is less than the third preset threshold value Tb (the critical value parameter for determining whether the ice has melted), the refrigeration time of the warm cooling mode is increased according to the third preset ratio.

[0055] Step S24, when the third air outlet temperature is not less than the second preset threshold value Ta, or when the third air outlet temperature is less than the second preset threshold value Ta and the temperature difference is not less than the third preset threshold value Tb, keep the cooling time of the cold cooling mode and the cooling time of the warm cooling mode unchanged.

[0056] During the use of the refrigerator, if the gear is too low or the load is large, the refrigerator will blow cold air for a long time, resulting in a low temperature near the air outlet, causing food to freeze at the refrigerator outlet. Through the above steps, the first air outlet temperature of the refrigerator outlet of the refrigeration equipment is detected; heating is performed in the refrigerator air duct according to the first air outlet temperature to control the temperature of the air outlet within a preset temperature range. The preset temperature range is a temperature range used to prevent freezing, which can solve the technical problem of freezing at the refrigerator outlet in the related art.

[0057] Example 2

[0058] In the technical solution of the present application, a heater is added at the initial location of the refrigerated air duct (such as the middle of the duct, the edge of the duct, i.e., the refrigerated air door) to control the refrigerated air outlet temperature, and a temperature sensor is added at the refrigerated air outlet to control the air outlet temperature and air outlet time in combination with the heater to prevent the refrigerated air outlet from freezing and increase the freshness of food; considering that the use of this solution will result in the problem of too long refrigeration time, in order to ensure the refrigeration efficiency of the refrigerator, a solution is also provided to maintain the refrigeration efficiency without freezing. As an optional embodiment, the technical solution of the present application is further described in detail below in combination with the specific implementation method:

[0059] In the operation of air-cooled frost-free refrigerators, most of them are single evaporators. The refrigerant system and the refrigeration of the refrigerator compartment are directly cooled by the cold energy provided by the evaporator to the refrigerator compartment. Although there will be a certain temperature rise after passing through the longer air duct path, the temperature is still far below 0°C. Under certain working conditions, such as the refrigeration gear is adjusted to 2°C, the high-load ambient temperature will cause the refrigeration to run for a long time at a time, and the colder air outlet temperature will cause the food near the refrigeration outlet to freeze. The present application provides a solution to prevent ice from forming at the refrigeration outlet, which can ensure the preservation of food.

[0060] Considering that the reason for ice in the refrigerator compartment is that the air outlet temperature of the refrigerator is too low and is blown directly for a long time, when the wind is dispersed into the interior of the box, the temperature will exchange heat with the air in the box and rise, so ice occurs at the air outlet. The temperature of the air outlet is relatively low and has not risen yet. Usually the temperature at the air duct outlet is below -10℃, and when the air is out for a long time, ice will occur.

[0061] Therefore, the improvements of this application are determined based on the two characteristics of low temperature and long time. First, a heater is added at the initial air outlet, that is, the refrigeration damper, to make the air outlet temperature higher than zero degrees; considering that low air outlet temperature will lead to reduced refrigeration efficiency and too long refrigeration time, a period of original refrigeration refrigeration (that is, without turning on the heater) and a period of warm refrigeration (turning on the heater) are used. The temperature t0 can be used for judgment. If it is low, the efficiency is sufficient, and if it is high, it is not. Use alternating cold and warm. Figure 2 :

[0062] Step S21, when there is a cooling demand in the refrigerating chamber, the refrigerating chamber is cooled in the warm cooling mode. It is determined whether the current temperature t is lower than the temperature t0, if so, step S22 is executed, otherwise step S23 is executed.

[0063] Step S22, achieving the refrigeration demand in the warm cooling mode.

[0064] The situation where food freezes at the refrigeration outlet is because the overcooled air from the outlet blows to one place for a long time, causing the local temperature to be below 0°C for a long time, resulting in the food freezing at the outlet. In this application scheme, the refrigeration refrigeration preferably uses the warm cooling mode to cool the refrigeration room, that is, the heater installed in the refrigeration air duct is used to make the outlet temperature higher than 0°C, such as Figure 3 As shown:

[0065] Step S221, the initial power of the heater is set to P0.

[0066] Step S222, the heater power is controlled by feedback from the refrigerated air outlet sensor T0 (real-time temperature of the refrigerated air outlet), that is, when the outlet sensor T0 temperature is lower than 0°C, the heater power is increased by one level, and when the outlet sensor T0 temperature is higher than Tc (used to control the upper limit of the air outlet temperature in the heating and cooling mode), the heater power is reduced by one level. The power difference between each level is 0.05 times, one level higher is 1.05P0, and two levels higher is 1.10P0, so that the outlet temperature is maintained at 0°C<T0<Tc, and the outlet temperature is kept close to 0°C but not lower than 0°C, which can ensure the maximum cooling efficiency without freezing.

[0067] Step S23, the refrigeration demand is met by the alternating cooling and heating refrigeration mode.

[0068] If the refrigeration time is long in the warm cooling mode, it means that the warm cooling efficiency is insufficient under high load conditions, so the two cooling modes of cold cooling and warm cooling are used alternately. Determine the time of cold and warm: a sensor will be installed at the air outlet. After each cold cooling and warm cooling time period in the cold and warm alternation, there will be a balance time period. The end time is considered to be the temperature at the air outlet. Use this to adjust the time ratio of cold cooling and warm cooling. Figure 4 As shown:

[0069] Step S231, firstly, the cold refrigeration mode is performed, and a certain downtime period t3 is performed after the end of the refrigeration cycle t1. After the end of period t3, the temperature of the refrigerated air outlet is recorded and recorded as T1 (the temperature of the refrigerated air outlet sensor after the end of the cold refrigeration cycle t3, which is used to represent the temperature level of the air outlet after the end of the cold refrigeration cycle), which can also be used to represent the temperature of food near the air outlet after the end of the cold refrigeration cycle. Then, the warm refrigeration cycle is performed, and a downtime period t3 is performed after the end of the warm refrigeration cycle t2. After the end of period t3, the temperature of the refrigerated air outlet is recorded and recorded as T2 (the temperature of the refrigerated air outlet sensor after the end of the warm refrigeration cycle t3, which is used to represent the temperature level of the air outlet after the end of the warm refrigeration cycle), which can also be used to represent the temperature of food near the air outlet after the end of the warm refrigeration cycle.

[0070] Step S232, T1<Ta, the lower temperature indicates the presence of ice, T2-T1=△T<Tb indicates the temperature difference between cold cooling and warm cooling is poor, indicating that the ice is not melted during the warm cooling cycle, then the warm cooling cycle duration t3 is increased until the conditions T1<Ta, T2-T1=△T>Tb are met, T1<Ta indicates ice, T2-T1=△T>Tb, the ice is melted after the warm cooling cycle. If T1>Ta, it means that there is no ice after the cold cooling cycle, then the warm cooling cycle can be reduced or no warm cooling cycle is required.

[0071] It should be noted that, for the aforementioned method embodiments, for the sake of simplicity, they are all expressed as a series of action combinations, but those skilled in the art should be aware that the present application is not limited by the described order of actions, because according to the present application, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by the present application.

[0072] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in each embodiment of the present application.
