Technical Field

[0001] The present disclosure relates to the technical field of intelligent refrigerators, and particularly to a temperature equalization control method and a refrigerator for a refrigerator. Background Art

[0002] With the continuous change of the needs of refrigerator users, the functions of refrigerators have become increasingly rich. The temperature control inside the refrigerator usually forces the cold air around the evaporator to circulate between the freezer and the refrigerator compartment through the air damper and the blower, so as to lower the temperature of the refrigerator compartment. The refrigerator air damper controls the temperature mainly through the blower. The blower can adjust the cold air flow rate, thereby realizing the control of the temperature in the refrigerator compartment.

[0003] The temperature sensor in the refrigerator compartment of a traditional refrigerator is placed at a certain position in the refrigerator. During the process of cold air flowing from the freezer to the refrigerator compartment, the cold air sinks, resulting in a large difference in the actual temperatures of each compartment in the refrigerator compartment. There is an uneven situation where the temperature is lower in some positions and higher in some positions. The value measured by the temperature sensor is only a reflection of the local temperature in the refrigerator compartment of the refrigerator, and cannot represent the temperature of the entire compartment, resulting in a poor temperature equalization effect of the refrigerator and reducing the user experience.

[0051] Figure 5 is a flowchart of the operation of a refrigerator shown according to an exemplary embodiment. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0052] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0053] With the progress of technology and the improvement of people's living standards, the requirements for intelligent control of refrigerators are getting higher and higher. Currently, the temperature control of the refrigerating compartment in the refrigerator industry is relatively simple, and there are significant differences in the actual temperatures of the refrigerators. To meet the different storage purposes of users, multiple compartments are usually provided in the refrigerator, and each compartment can be refrigerated or not according to the user's needs. When the temperature requirements of each compartment are different, the temperature of each compartment is controlled through the refrigerator air damper. The refrigerator air damper controls the temperature mainly through the fan. The fan can adjust the cold air flow, thus achieving the temperature control of each compartment.

[0054] In the related art, the measured value of a temperature sensor set in the refrigerating compartment and the freezing compartment of the refrigerator cannot represent the actual temperature of the entire compartment, but only the local temperature of the temperature sensor. Moreover, during the process of the user opening the refrigerator door, the opening speed and opening angle are in an uncertain state, and it is difficult to reflect the real state only by the opening coefficient; in addition, in different seasons, the ambient temperature is different, the atmospheric pressure outside is different, and during the process of opening the door, the heat exchange speed between the cold air and the outside air is different. Due to natural convection, the cold air sinks, resulting in large actual temperature differences and poor temperature uniformity among the compartments in the refrigerating compartment. The temperature differences are relatively large. The relatively low temperature at some positions may cause icing, resulting in freezing of food; the relatively high temperature at some positions is not conducive to storing food, making the temperature control of each compartment of the refrigerator inaccurate, thereby reducing the user experience.

[0055] To solve the above technical problems, the present disclosure provides an average temperature control method for a refrigerator. As Figure 1 shown. An average temperature control method for a refrigerator, the method includes:

[0056] S10. Detect the real-time pressure of each refrigerating compartment in the refrigerating compartment of the refrigerator, and obtain the average pressure of the refrigerating compartment;

[0057] S20. Compare the obtained average pressure of the refrigerating compartment with the pressure corresponding to the preset temperature, and adjust the temperature in the refrigerating compartment according to the comparison result.

[0058] It should be noted that the value of the pressure is closer to the real temperature of the refrigerating compartment, and each pressure corresponds to a temperature.

[0059] The preset temperature is the temperature of the refrigerating chamber selected by the user when using the refrigerator, and the corresponding pressure of the preset temperature. As shown in Table 1, for example, the pressures corresponding to different preset temperatures in the refrigerating compartment.

[0060] Table 1 Pressures corresponding to different preset temperatures in the refrigerating compartment

[0061]

[0062] Among them, the real-time pressure of the refrigerating compartment is the pressure detected in the refrigerator's refrigerating chamber every unit time.

[0063] The unit time can be 3 seconds, 5 seconds, 8 seconds, etc., and the present disclosure does not make specific limitations thereto.

[0064] Exemplarily, when the number of refrigerating compartments is 3, that is, the pressure of the first refrigerating compartment is P1, the pressure of the second refrigerating compartment is P2, and the pressure of the third refrigerating compartment is P3, then the average pressure Pave of the refrigerating chamber is (P1 + P2 + P3) / 3. Compare the obtained average pressure Pave of the refrigerating chamber with the pressure corresponding to the preset temperature, and adjust the temperature in the refrigerating chamber according to the comparison result.

[0065] Exemplarily, when the number of refrigerating compartments is 4, that is, the pressure of the first refrigerating compartment is P1, the pressure of the second refrigerating compartment is P2, the pressure of the third refrigerating compartment is P3, and the pressure of the fourth refrigerating compartment is P4, then the average pressure Pave of the refrigerating chamber is (P1 + P2 + P3 + P4) / 4. Compare the obtained average pressure Pave of the refrigerating chamber with the pressure corresponding to the preset temperature, and adjust the temperature in the refrigerating chamber according to the comparison result.

[0066] Exemplarily, when the number of refrigerating compartments is 5, that is, the pressure of the first refrigerating compartment is P1, the pressure of the second refrigerating compartment is P2, the pressure of the third refrigerating compartment is P3, the pressure of the fourth refrigerating compartment is P4, and the pressure of the fifth refrigerating compartment is P5, then the average pressure Pave of the refrigerating chamber is (P1 + P2 + P3 + P4 + P5) / 5. Compare the obtained average pressure Pave of the refrigerating chamber with the pressure corresponding to the preset temperature, and adjust the temperature in the refrigerating chamber according to the comparison result.

[0067] Adopting the above technical solution, the present disclosure provides an even-temperature control method for a refrigerator, which detects the real-time pressure of each refrigerating compartment in the refrigerator's refrigerating chamber and obtains the average pressure of the refrigerating chamber; compares the obtained average pressure of the refrigerating chamber with the pressure corresponding to the preset temperature, and adjusts the temperature in the refrigerating chamber according to the comparison result. Characterizing the temperature through the collected pressure data can more truly reflect the temperature of each compartment in the refrigerating chamber, the control effect is more uniform, the temperature difference is smaller, the temperature difference between compartments is reduced, the even-temperature effect of each compartment in the refrigerator's refrigerating chamber is improved, and further the temperature control of the refrigerator's refrigerating chamber is more accurate, enhancing the user experience.

[0068] In some possible implementation manners, as Figure 2 shown, S20. Comparing the obtained average pressure of the refrigerating chamber with the pressure corresponding to the preset temperature, and adjusting the temperature in the refrigerating chamber according to the comparison result includes:

[0069] S201. When the average pressure is greater than or equal to the first pressure corresponding to the preset temperature, enter the coarse adjustment mode until the average pressure is equal to the second pressure corresponding to the preset temperature.

[0070] It can be understood that whether to enter the coarse adjustment mode is selected according to the comparison between the average pressure and the first pressure. For example, when the average pressure is greater than the first pressure, that is, when the average temperature in the refrigerating chamber is higher than the first reference temperature, the first reference temperature is the temperature corresponding to the first pressure, and the first reference temperature is greater than the preset temperature, enter the coarse adjustment mode; whether to exit the coarse adjustment mode is selected according to the comparison between the average pressure and the second pressure. For example, when the average pressure is equal to the second pressure, that is, when the average temperature in the refrigerating chamber is equal to the second reference temperature, the second reference temperature is the temperature corresponding to the second pressure, and the second reference temperature is greater than the preset temperature, exit the coarse adjustment mode.

[0071] Among them, the value of the first pressure is greater than the value of the second pressure.

[0072] Specifically, the relationship between the first pressure and the pressure corresponding to the preset temperature is:

[0073] P ref0 = η0·Psec

[0074] where, P ref0 is the first pressure, η0 is the coefficient factor, and Psec is the pressure corresponding to the preset temperature of the refrigerating chamber selected by the user when using the refrigerator.

[0075] The relationship between the second pressure and the pressure corresponding to the preset temperature is:

[0076] P ref1 = η1·Psec

[0077] where, P ref1is the second pressure, η1 is the coefficient factor, and Psec is the pressure corresponding to the preset temperature of the refrigerating chamber selected by the user when using the refrigerator.

[0078] It includes the following two situations:

[0079] In one situation, when the average pressure is greater than the first pressure corresponding to the preset temperature, enter the coarse adjustment mode until the average pressure is equal to the second pressure corresponding to the preset temperature.

[0080] In the other situation, when the average pressure is equal to the first pressure corresponding to the preset temperature, enter the coarse adjustment mode until the average pressure is equal to the second pressure corresponding to the preset temperature.

[0081] In the embodiments of the present disclosure, the temperature is characterized by the collected pressure data, which can more truly reflect the temperature of each compartment in the refrigerating chamber. According to the comparison between the average pressure and the first pressure and the second pressure, it is selected whether to enter the coarse adjustment mode and whether to exit the coarse adjustment mode, thereby controlling the temperature of the refrigerating chamber of the refrigerator more accurately and improving the user experience.

[0082] In some possible implementation manners, as Figure 2 shown, S20. Comparing the obtained average pressure of the refrigerating chamber with the pressure corresponding to the preset temperature and adjusting the temperature in the refrigerating chamber according to the comparison result further includes:

[0083] S202. When the average pressure is equal to the second pressure corresponding to the preset temperature, exit the coarse adjustment mode and determine whether to enable the fine adjustment mode.

[0084] It can be understood that according to the comparison between the average pressure and the second pressure, it is selected whether to exit the coarse adjustment mode and whether to enable the fine adjustment mode.

[0085] For example, when the average pressure is equal to the second pressure, that is, when the average temperature in the refrigerating chamber is equal to the second reference temperature, the second reference temperature is the temperature corresponding to the second pressure, and the second reference temperature is greater than the preset temperature, exit the coarse adjustment mode and determine whether to enable the fine adjustment mode.

[0086] In the embodiments of the present disclosure, the temperature is characterized by the collected pressure data, which can more truly reflect the temperature of each compartment in the refrigerating chamber. According to the comparison between the average pressure and the second pressure, it is selected whether to exit the coarse adjustment mode and whether to enable the fine adjustment mode, thereby controlling the temperature of the refrigerating chamber of the refrigerator more accurately and improving the user experience.

[0087] In some possible implementation manners, as Figure 2 shown, S20. Comparing the obtained average pressure of the refrigerating chamber with the pressure corresponding to the preset temperature and adjusting the temperature in the refrigerating chamber according to the comparison result further includes:

[0088] S203. When the average pressure is less than the first pressure, directly determine whether to enable the fine-tuning mode.

[0089] It can be understood that whether to enable the fine-tuning mode is directly determined based on the comparison between the average pressure and the first pressure.

[0090] Exemplarily, when the number of refrigerated compartments is 3, that is, the pressure of the first refrigerated compartment is P1, the pressure of the second refrigerated compartment is P2, and the pressure of the third refrigerated compartment is P3, then the average pressure Pave of the refrigerated chamber is (P1 + P2 + P3) / 3. Compare the obtained average pressure Pave of the refrigerated chamber with the first pressure corresponding to the preset temperature. When the average pressure Pave is less than the first pressure, directly determine whether to enable the fine-tuning mode to adjust the temperature in the refrigerated chamber.

[0091] Exemplarily, when the number of refrigerated compartments is 4, that is, the pressure of the first refrigerated compartment is P1, the pressure of the second refrigerated compartment is P2, the pressure of the third refrigerated compartment is P3, and the pressure of the fourth refrigerated compartment is P4, then the average pressure Pave of the refrigerated chamber is (P1 + P2 + P3 + P4) / 4. Compare the obtained average pressure Pave of the refrigerated chamber with the first pressure corresponding to the preset temperature. When the average pressure Pave is less than the first pressure, directly determine whether to enable the fine-tuning mode to adjust the temperature in the refrigerated chamber.

[0092] Exemplarily, when the number of refrigerated compartments is 5, that is, the pressure of the first refrigerated compartment is P1, the pressure of the second refrigerated compartment is P2, the pressure of the third refrigerated compartment is P3, the pressure of the fourth refrigerated compartment is P4, and the pressure of the fifth refrigerated compartment is P5, then the average pressure Pave of the refrigerated chamber is (P1 + P2 + P3 + P4 + P5) / 5. Compare the obtained average pressure Pave of the refrigerated chamber with the first pressure corresponding to the preset temperature. When the average pressure Pave is less than the first pressure, directly determine whether to enable the fine-tuning mode to adjust the temperature in the refrigerated chamber.

[0093] In some possible implementation manners, as Figure 3 shown, the method for determining whether to enable the fine-tuning mode includes:

[0094] S301. Compare the pressure corresponding to the preset temperature with the pressure value for starting the fine-tuning mode respectively, and obtain a first comparison value;

[0095] S302. Compare the pressure corresponding to the preset temperature with the pressure value for exiting the fine-tuning mode respectively, and obtain a second comparison value, where the second comparison value is less than the first comparison value;

[0096] S303. Compare the real-time pressure of each cold storage compartment in the refrigerating chamber with the first comparison value and the second comparison value to determine whether the real-time pressure of each cold storage compartment meets the conditions for starting and / or exiting the fine-tuning mode.

[0097] Among them, both the first comparison value and the second comparison value are set values. For example, the first comparison value can be the pressure corresponding to 1.05 times the preset temperature; the second comparison value can be the pressure corresponding to 0.95 times the preset temperature. Both the first comparison value and the second comparison value are pressures close to the pressure corresponding to the preset temperature and fluctuate within the range of (1 ± 0.05) times the pressure corresponding to the preset temperature.

[0098] Exemplarily, when the number of cold storage compartments is 3, that is, the pressure of the first cold storage compartment is P1, the pressure of the second cold storage compartment is P2, and the pressure of the third cold storage compartment is P3, respectively compare the obtained pressure P1 of the first cold storage compartment, pressure P2 of the second cold storage compartment, and pressure P3 of the third cold storage compartment with the first comparison value, that is, the pressure corresponding to 1.05 times the preset temperature, and the second comparison value, that is, the pressure corresponding to 0.95 times the preset temperature, to determine whether the pressure P1 of the first cold storage compartment, pressure P2 of the second cold storage compartment, and pressure P3 of the third cold storage compartment meet the conditions for starting and / or exiting the fine-tuning mode.

[0099] Exemplarily, when the number of cold storage compartments is 4, that is, the pressure of the first cold storage compartment is P1, the pressure of the second cold storage compartment is P2, the pressure of the third cold storage compartment is P3, and the pressure of the fourth cold storage compartment is P4, respectively compare the obtained pressure P1 of the first cold storage compartment, pressure P2 of the second cold storage compartment, pressure P3 of the third cold storage compartment, and pressure P4 of the fourth cold storage compartment with the first comparison value, that is, the pressure corresponding to 1.05 times the preset temperature, and the second comparison value, that is, the pressure corresponding to 0.95 times the preset temperature, to determine whether the pressure P of the first cold storage compartment, pressure P2 of the second cold storage compartment, pressure P3 of the third cold storage compartment, and pressure P4 of the fourth cold storage compartment meet the conditions for starting and / or exiting the fine-tuning mode.

[0100] Exemplarily, when the number of refrigerated compartments is 5, that is, the pressure of the first refrigerated compartment is P1, the pressure of the second refrigerated compartment is P2, the pressure of the third refrigerated compartment is P3, the pressure of the fourth refrigerated compartment is P4, and the pressure of the fifth refrigerated compartment is P5. The obtained pressures P1, P2, P3, P4, and P5 of the first, second, third, fourth, and fifth refrigerated compartments are respectively compared with the pressure corresponding to the preset temperature of 1.05 times the first comparison value and the pressure corresponding to the preset temperature of 0.95 times the second comparison value, to determine whether the pressures P1, P2, P3, P4, and P5 of the first, second, third, fourth, and fifth refrigerated compartments meet the conditions for starting and / or exiting the fine-tuning mode.

[0101] In some possible implementation manners, as Figure 3 shown, the conditions for meeting the start of the fine-tuning mode and / or exiting the fine-tuning mode include:

[0102] S3031. When the real-time pressure is greater than or equal to the first comparison value, start the fine-tuning mode until the real-time pressure is less than or equal to the second comparison value, and then exit the fine-tuning mode;

[0103] S3032. When the real-time pressure is less than the second comparison value, directly exit the fine-tuning mode.

[0104] It includes the following two situations:

[0105] One situation is that when the real-time pressure is greater than the first comparison value, start the fine-tuning mode until the real-time pressure is less than or equal to the second comparison value, and then exit the fine-tuning mode;

[0106] When the real-time pressure is less than the second comparison value, directly exit the fine-tuning mode.

[0107] Another situation is that when the real-time pressure is equal to the first comparison value, start the fine-tuning mode until the real-time pressure is less than or equal to the second comparison value, and then exit the fine-tuning mode;

[0108] When the real-time pressure is less than the second comparison value, directly exit the fine-tuning mode.

[0109] In the embodiments of the present disclosure, the temperature of each refrigerated compartment in the refrigerator freezer is adjusted through the fine-tuning mode, thereby making the temperature control of the refrigerator freezer more accurate and improving the user experience.

[0110] Based on the same inventive concept, the present disclosure provides a refrigerator applying the average temperature control method of any of the above embodiments of the refrigerator. As Figure 4 shown, the refrigerator includes: a freezer compartment 1, a refrigerator compartment 2, a partition 3, an air duct 4, and a pressure sensor 7.

[0111] The partition plate 3 is arranged between the freezer compartment 1 and the refrigerator compartment 2 for separating the freezer compartment 1 and the refrigerator compartment 2;

[0112] The air duct 4 is used to connect the freezer compartment 1 and the refrigerator compartment 2. An air door 5 is installed in the air duct 4, and an air outlet hole 6 communicating with the refrigerator compartment 2 is arranged on the air duct 4;

[0113] The pressure sensor 7 is arranged in the refrigerator compartment 2 and installed on the partition plate 3,

[0114] wherein, the pressure sensor 7 detects the pressure in the refrigerator compartment 2 in real time to adjust the temperature of the refrigerator compartment 2 and perform temperature equalization control.

[0115] The pressure sensor 7 converts the pressure in each refrigerated compartment in the refrigerator compartment 2 into an electrical signal, which is characterized by a digital value.

[0116] Adopting the above technical solution, the present disclosure characterizes the temperature through the pressure data collected by the pressure sensor 7, which can more truly reflect the temperature of each compartment in the refrigerator compartment 2. The control effect is more uniform, the temperature difference is smaller, the temperature difference between compartments is reduced, the temperature equalization effect of each compartment in the refrigerator compartment 2 of the refrigerator is improved, and thus the temperature control of the refrigerator compartment 2 of the refrigerator is more accurate, improving the user experience.

[0117] In some possible implementation manners, as Figure 4 shown, the air outlet hole 6 is configured as a micro-cooling unit.

[0118] There may be multiple air outlet holes 6, and the micro-cooling unit can adjust the temperature of the refrigerator compartment 2 in a small range.

[0119] Exemplarily, the air outlet hole 6 may be three, that is, the micro-cooling unit is three. Each micro-cooling unit can adjust the temperature of the corresponding refrigerated compartment in the refrigerator compartment 2 in a small range. For the temperature of each compartment in the refrigerator compartment 2, the control effect is more uniform, the temperature difference is smaller, the temperature difference between compartments is reduced, the temperature equalization effect of each compartment in the refrigerator compartment 2 of the refrigerator is improved, and thus the temperature control of the refrigerator compartment 2 of the refrigerator is more accurate, improving the user experience.

[0120] Exemplarily, the air outlet hole 6 may be four, that is, the micro-cooling unit is four. Each micro-cooling unit can adjust the temperature of the corresponding refrigerated compartment in the refrigerator compartment 2 in a small range. For the temperature of each compartment in the refrigerator compartment 2, the control effect is more uniform, the temperature difference is smaller, the temperature difference between compartments is reduced, the temperature equalization effect of each compartment in the refrigerator compartment 2 of the refrigerator is improved, and thus the temperature control of the refrigerator compartment 2 of the refrigerator is more accurate, improving the user experience.

[0121] Exemplarily, there may be five air outlets 6, that is, five micro-cooling units. Each micro-cooling unit can adjust the temperature of the corresponding cold storage compartment in the refrigerating chamber 2 within a small range. For the temperatures of each compartment in the refrigerating chamber 2, the control effect is more uniform, the temperature difference is smaller, the temperature difference between compartments is reduced, the temperature equalization effect of each compartment in the refrigerator's refrigerating chamber 2 is improved, and thus the temperature control of the refrigerator's refrigerating chamber 2 is more accurate, enhancing the user experience.

[0122] In some possible implementation manners, such as Figure 4 shown, the refrigerator further includes: an evaporator (not shown in the figure) and a blower 8.

[0123] The evaporator is installed at the lower part of the freezer compartment 1;

[0124] The blower 8 is installed in the refrigerator and is far from the evaporator,

[0125] wherein, the blower 8 forces the cold air around the evaporator to circulate between the freezer compartment 1 and the refrigerating chamber 2, adjusts the temperature of the refrigerating chamber 2 and performs temperature equalization control.

[0126] The blower 8 rotates the fan to force the cold air around the evaporator to circulate between the freezer compartment 1 and the refrigerating chamber 2, adjusts the temperature of the refrigerating chamber 2 and performs temperature equalization control.

[0127] In the embodiment of the present disclosure, when the average pressure of each pressure sensor 7 in the refrigerating chamber 2 is greater than or equal to the first pressure corresponding to the preset temperature, the air duct 4 is activated, the blower 8 is turned on, and the rough adjustment mode is entered until the average pressure is equal to the second pressure corresponding to the preset temperature, the rough adjustment mode is exited, and it is determined whether to start the fine adjustment mode to adjust the temperature of the corresponding cold storage compartment in the refrigerating chamber 2. For the temperatures of each compartment in the refrigerating chamber 2, the control effect is more uniform, the temperature difference is smaller, the temperature difference between compartments is reduced, the temperature equalization effect of each compartment in the refrigerator's refrigerating chamber 2 is improved, and thus the temperature control of the refrigerator's refrigerating chamber 2 is more accurate, enhancing the user experience.

[0128] In some possible implementation manners, such as Figure 4 shown, the refrigerator further includes: a controller 9.

[0129] The controller 9 is used to control any one or more of the blower 8, the evaporator, the air damper 5, and the pressure sensor 7.

[0130] Among them, the controller 9 uses a microcontroller unit (MCU), also known as a single-chip microcomputer or a single-chip MCU, as the logical control unit of the refrigerator to control the operation of the refrigerator, such as a single-chip microcomputer.

[0131] Specifically, Psec is the pressure corresponding to the temperature of the refrigerating chamber 2 selected by the user when using the refrigerator, that is, the pressure corresponding to the preset temperature.

[0132] The relationship between the first pressure and the pressure corresponding to the preset temperature is:

[0133] P ref0 = η0·Psec

[0134] where P ref0 is the first pressure, η0 is the coefficient factor, and Psec is the pressure corresponding to the preset temperature of the refrigerating chamber selected by the user when using the refrigerator.

[0135] When the average pressure is greater than or equal to the first pressure corresponding to the preset temperature, enter the coarse adjustment mode.

[0136] The relationship between the second pressure and the pressure corresponding to the preset temperature is:

[0137] P ref1 = η1·Psec

[0138] where P ref1 is the second pressure, η1 is the coefficient factor, and Psec is the pressure corresponding to the preset temperature of the refrigerating chamber selected by the user when using the refrigerator.

[0139] In the coarse adjustment mode, until the average pressure is equal to the second pressure corresponding to the preset temperature, exit the coarse adjustment mode, and determine whether to enable the fine adjustment mode.

[0140] In the embodiment of the present disclosure, the controller 9 is used as the logical control unit of the refrigerator to control the operation of the refrigerator. The pressure data collected by the pressure sensor 7 represents the temperature, which can more truly reflect the temperature of each compartment in the refrigerating chamber 2. The temperature control of the refrigerating chamber of the refrigerator is more accurate through the coarse adjustment mode and the fine adjustment mode, improving the user experience.

[0141] In some possible implementation manners, as Figure 4 shown, the refrigerating chamber 2 includes:

[0142] a plurality of refrigerating compartments 21, and each refrigerating compartment 21 includes at least one pressure sensor 7 and at least one air outlet 6.

[0143] It should be noted that the number of the refrigerating compartments 21 is n, and P1, P2... Pn are the pressures of the 1-n refrigerating compartments 21 in each refrigerating compartment 21.

[0144] The average pressure Pave of the refrigerating chamber = (P1 + P2 + P3 +... + Pn) / n;

[0145] The preset temperature is the temperature of the refrigerating chamber 2 selected by the user when using the refrigerator, and the pressure corresponding to this preset temperature is Psec.

[0146] The relationship between the first pressure and the pressure corresponding to the preset temperature is as follows:

[0147] P ref0 = η0·Psec

[0148] Wherein, P ref0 is the first pressure, η0 is the coefficient factor, and Psec is the pressure corresponding to the preset temperature of the refrigerating chamber selected by the user when using the refrigerator.

[0149] The relationship between the second pressure and the pressure corresponding to the preset temperature is as follows:

[0150] P ref1 = η1·Psec

[0151] Wherein, P ref1 is the second pressure, η1 is the coefficient factor, and Psec is the pressure corresponding to the preset temperature of the refrigerating chamber selected by the user when using the refrigerator.

[0152] As Figure 5 shown, the working process of the refrigerator is as follows:

[0153] When the user uses the refrigerator, the temperature of the refrigerating chamber 2 selected is the set preset temperature, and the pressure corresponding to this preset temperature is Psec. When the refrigerator is powered on and starts to work, each pressure sensor 7 in the refrigerating chamber 2 is initialized, and the controller 9 controls the pressure sensor 7 to detect the pressure in the refrigerating chamber 2 of the refrigerator every unit time to obtain the corresponding pressures P1, P2... Pn in each refrigerating compartment 21;

[0154] According to the obtained corresponding pressures P1, P2... Pn in each refrigerating compartment 21, the average pressure Pave of the refrigerating chamber is obtained; according to Psec, the first pressure P ref0 , the second pressure P ref1 , and the value of the first pressure P ref0 is greater than the value of the second pressure P ref1 .

[0155] If the average pressure Pave is greater than or equal to the first pressure P ref0 , enter the coarse adjustment mode, the controller 9 starts the air duct 4 and turns on the fan 8, so that the cold air in the freezer 1 enters the refrigerating chamber 2 until the average pressure Pave is equal to the second pressure P ref1 , exit the coarse adjustment mode, the controller 9 closes the air duct 4, and determines whether to start the fine adjustment mode.

[0156] If the average pressure Pave is less than the first pressure P ref0 , directly determine whether to start the fine adjustment mode.

[0157] In the fine-tuning mode, the pressures corresponding to the preset temperatures are respectively compared with the pressure value for starting the fine-tuning mode to obtain a first comparison value; the pressures corresponding to the preset temperatures are respectively compared with the pressure value for exiting the fine-tuning mode to obtain a second comparison value; both the first comparison value and the second comparison value are set values. For example, the first comparison value can be 1.05Psec; the second comparison value can be 0.95Psec.

[0158] For temperature adjustment of each refrigerated compartment 21, taking the first refrigerated compartment as an example: If P1 is greater than or equal to 1.05Psec, the controller 9 opens the air outlet hole 6 in the first refrigerated compartment and starts the fine-tuning mode until P1 is less than 0.95Psec, then the controller 9 closes the air outlet hole 6 in the first refrigerated compartment and closes the air duct 4 to exit the fine-tuning mode;

[0159] If P1 is less than 0.95Psec, the controller 9 closes the air outlet hole 6 in the first refrigerated compartment and closes the air duct 4 to exit the fine-tuning mode.

[0160] Taking the second refrigerated compartment as an example: If P2 is greater than or equal to 1.05Psec, the controller 9 opens the air outlet hole 6 in the second refrigerated compartment and starts the fine-tuning mode until P2 is less than 0.95Psec, then the controller 9 closes the air outlet hole 6 in the second refrigerated compartment and closes the air duct 4 to exit the fine-tuning mode;

[0161] If P2 is less than 0.95Psec, the controller 9 closes the air outlet hole 6 in the second refrigerated compartment and closes the air duct 4 to exit the fine-tuning mode.

[0162] Taking the nth refrigerated compartment as an example: If P n is greater than or equal to 1.05Psec, the controller 9 opens the air outlet hole 6 in the nth refrigerated compartment and starts the fine-tuning mode until P n is less than 0.95Psec, the controller 9 closes the air outlet hole 6 in the nth refrigerated compartment and closes the air duct 4 to exit the fine-tuning mode;

[0163] If P n is less than 0.95Psec, the controller 9 closes the air outlet hole 6 in the nth refrigerated compartment and closes the air duct 4 to exit the fine-tuning mode.

[0164] The pressure sensor 7 detects the pressures of each refrigerated compartment in the refrigerator compartment 2 at each unit time, and adjusts the temperature of the refrigerator in such a cycle.

[0165] For the refrigerator provided by the present disclosure, the temperature control effect on each refrigerated compartment is more uniform, the temperature difference is smaller, the temperature difference between compartments is reduced, the temperature equalization effect of each compartment in the refrigerator compartment 2 is improved, and further the temperature control of the refrigerator compartment 2 is more accurate, improving the user experience.
