[0043] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the embodiments of the present disclosure described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0045] Unless otherwise stated, the term "plurality" means two or more.

[0046] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0047] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0048] At the same speed, the greater the load of the refrigerator, the higher the heat generated by the compressor, and the higher the temperature rise of the components of the frequency conversion device. Under the same load, the higher the speed of the compressor, the higher the heat generated by the compressor, and the higher the temperature rise of the components of the frequency conversion device. Therefore, in the embodiment of the present disclosure, when the refrigerator is powered on for the first time and the temperature of the freezer compartment is greater than the first set value, during the startup process of the refrigerator corresponding to different compressor startup speeds in stages, the compressor startup speed corresponding to one or more startup stages of the refrigerator compressor can be reduced according to the freezer compartment temperature and the ambient temperature, and the corresponding compressor operating speed can be obtained, and the corresponding compressor speed control can be performed, that is, under the same load, the compressor speed is reduced, the heat generated by the compressor is reduced, and the components of the frequency conversion device in the compressor compartment are prevented from overheating, thereby improving the operating stability and safety of the compressor and the refrigerator.

[0049] Figure 1 FIG. 1 is a flow chart of a refrigerator startup control method provided by an embodiment of the present disclosure. Figure 1 As shown, the refrigerator startup control process includes:

[0050] Step 101: When it is determined that the refrigerator is powered on for the first time, the current temperature of the freezing compartment is obtained.

[0051] In some embodiments, determining that the conditions for the refrigerator to be powered on for the first time are met includes: when the refrigerator is powered on for the first time, determining that the conditions for the refrigerator to be powered on for the first time are met; when the refrigerator is in a power-off state for a power-off time exceeding a set time, if the refrigerator is powered on, determining that the conditions for the refrigerator to be powered on for the first time are met.

[0052] After the refrigerator is placed in the designated location, for example, embedded in a cabinet, the refrigerator is powered on for the first time, and it can be determined that the refrigerator meets the initial power-on requirements. Alternatively, the refrigerator has been powered off for a long time, for example, the set duration can be 8, 10 or 12 hours, etc. In this way, the power-off duration of the refrigerator is 20 hours, and the refrigerator is powered on again. If 20>12, it can be determined that the refrigerator meets the initial power-on requirements.

[0053] When it is determined that the refrigerator is powered on for the first time, the refrigerator can obtain the temperature of the freezer compartment of the refrigerator through a temperature acquisition device, such as a temperature sensor. The current power-on time corresponds to the current freezer compartment temperature.

[0054] Step 102: When the current freezing compartment temperature is greater than a first set value, the current ambient temperature is obtained.

[0055] The first set value can be -5°C, -2°C, or -6°C, etc. Thus, when the current freezer compartment temperature is greater than the first set value, it indicates that the freezer compartment temperature is relatively high, and the refrigerator compressor needs to be operated in stages. In the disclosed embodiment, it is necessary to reduce the frequency increase amplitude of one, two or more startup stages, thereby reducing the heat generated by the compressor and preventing the components of the frequency conversion device in the compressor compartment from overheating. The amplitude of the reduction can be determined according to the freezer compartment temperature and the ambient temperature of the environment in which the refrigerator is located. Therefore, when the current freezer compartment temperature is greater than the first set value, the current ambient temperature is obtained.

[0056] Step 103: according to the current freezing compartment temperature and the current ambient temperature, the compressor startup speed corresponding to one or more startup stages of the refrigerator compressor is reduced to obtain the corresponding compressor operating speed, and the corresponding compressor speed control is performed.

[0057] When the refrigerator is powered on for the first time, the refrigerator compressor needs to be operated at a frequency-upgraded stage in stages, where each startup stage can be divided according to the set time interval. For example, according to the performance of the refrigerator, the application season, the region, etc., a corresponding relationship between a startup operation time range, a startup stage, and the compressor operating frequency can be determined. In this way, the compressor operating frequency corresponding to each startup stage can be determined, and then the compressor startup speed corresponding to each startup stage can be obtained according to the conversion relationship between frequency and speed.

[0058] Table 1 is a corresponding relationship between a startup operation time range, a startup phase, and a compressor operating frequency provided in an embodiment of the present disclosure.

[0059] Startup runtime range Start-up phase Compressor operating frequency 0-30min Startup Phase 1 58hz 30-60min Startup Phase 2 70hz 60-90min Startup Phase 3 82hz …… …… …… 270-300min Startup Phase 10 Preset maximum frequency …… …… Preset maximum frequency 390min-420min Startup Phase 14 Preset maximum frequency

[0060] Table 1

[0061] Among them, the startup running time range corresponding to startup phase 1 is [0,30), that is, including 0min but excluding 30min, and the startup running time range corresponding to startup phase 2 is [30,60), that is, including 30min but excluding 60min, and so on. For example: after the refrigerator is powered on, the current startup running time reaches 30min. According to Table 1, it can be determined that the current startup phase is startup phase 2, and the corresponding current compressor operating frequency is 70hz. Therefore, according to the relationship between the speed n and the frequency f f=n / 60, it can be obtained that the current compressor startup speed of the compressor corresponding to the current startup phase can be 70*60=4200rpm.

[0062] Therefore, in the embodiment of the present disclosure, the compressor starting speed of the compressor corresponding to each starting stage can be obtained, wherein each starting stage of the refrigerator compressor is divided according to a set time interval.

[0063] After obtaining the compressor starting speed, the compressor starting speed in some starting stages needs to be reduced, thereby reducing the heat generated by the compressor, that is, in some embodiments, reducing the compressor starting speed corresponding to one or more starting stages of the refrigerator compressor to obtain the corresponding compressor operating speed includes: obtaining the current compressor starting speed of the compressor corresponding to the current starting stage, wherein each starting stage of the refrigerator compressor is divided according to a set time interval; when the current starting stage is the set starting stage, determining the current compressor decreasing speed that matches the current freezer compartment temperature and the current ambient temperature, and determining the difference between the current compressor starting speed and the current compressor decreasing speed as the current compressor operating speed.

[0064] Among them, the set startup stage can be one startup stage or two or more startup stages. For example, the set startup stage includes: startup stage 2 corresponding to 30-60min, or the set startup stage includes: startup stage 2 corresponding to 30-60min, startup stage 3 of 60-90min, startup stage 4 of 90-120min and startup stage 5 of 120-150min.

[0065] The refrigerator also stores the corresponding relationship between the freezing compartment temperature, the ambient temperature, the set startup phase, and the compressor down speed. Thus, when the current startup phase is the set startup phase, the current compressor down speed matching the current freezing compartment temperature and the current ambient temperature can be determined based on the stored corresponding relationship.

[0066] Table 2 shows the corresponding relationship between the freezing compartment temperature, the ambient temperature, the set startup phase and the compressor reduction speed provided by an embodiment of the present disclosure.

[0067] If the current startup operation time reaches 60 minutes after the refrigerator is powered on, the current startup stage can be determined as startup stage 3 according to Table 1, and the current startup stage can be determined as the set startup stage according to Table 2. At this time, if the current freezing compartment temperature is 10°C and the current ambient temperature is 25°C, according to Table 2, the current compressor down speed can be determined to be 270rpm. According to Table 1, the current compressor operating frequency can be determined to be 82hz, and the corresponding current compressor startup speed can be 82*60=4920rpm, so the current compressor operating speed is 4920-270=4650rpm.

[0068] Of course, in some embodiments, when the current startup phase is not the set startup phase, the current compressor startup speed can be determined as the current compressor operating speed. For example: if the current startup operation time reaches 270 minutes after the refrigerator is powered on, it can be determined that the current startup phase is startup phase 10 according to Table 1, and it can be determined that the current startup phase is not the set startup phase according to Table 2. Thus, according to Table 1, it can be determined that the current compressor operating frequency is the preset maximum frequency, for example, the preset maximum frequency is 200hz, and the corresponding current compressor startup speed can be 200*60=12000rpm, so that the current compressor operating speed is also 12000rpm.

[0069] By determining the compressor speed corresponding to each startup stage, the corresponding compressor speed control can be performed. For example, the compressor speed corresponding to startup stage 3 is 4920-270=4650rpm, which means that within 60-90 minutes after the refrigerator is powered on, the compressor can be controlled to run at a speed of 4650rpm.

[0070] It can be seen that in the disclosed embodiment, when the refrigerator is powered on for the first time and the temperature of the freezer compartment is greater than the first set value, during the startup process of the refrigerator in stages corresponding to different compressor starting speeds, the compressor starting speed corresponding to one or more startup stages of the refrigerator compressor can be reduced according to the freezer compartment temperature and the ambient temperature, the corresponding compressor operating speed is obtained, and the corresponding compressor speed control is performed, that is, under the same load condition, the compressor speed is reduced, the heat generated by the compressor is reduced, and the components of the frequency conversion device in the compressor compartment are prevented from overheating, thereby improving the operating stability and safety of the compressor and the refrigerator.

[0071]

[0072] Table 2

[0073] Reducing the heat generated by the compressor can reduce the heat in the compressor compartment of the refrigerator. Not only that, in some embodiments, the heat dissipation of the compressor compartment can also be accelerated, that is, when the current freezer compartment temperature is greater than the first set value, after obtaining the current ambient temperature, it can also include: obtaining the current fan speed of the cooling fan corresponding to the current startup stage, wherein each startup stage of the refrigerator compressor is divided according to a set time interval; determining a current boost ratio that matches the current freezer compartment temperature and the current ambient temperature, and according to the current boost ratio, boosting the current fan speed to obtain the current fan operating speed, and performing corresponding cooling fan speed control.

[0074] When the refrigerator is powered on for the first time, the refrigerator compressor will be operated in stages with increased frequency. The corresponding cooling fan also needs to run to dissipate heat from the compressor compartment. Each startup stage has a corresponding fan speed of the cooling fan. Of course, each startup stage can also be divided according to the set time interval.

[0075] Thus, based on the corresponding relationship between the saved startup stage and the fan speed of the cooling fan, the current fan speed of the cooling fan corresponding to the current startup stage can be obtained. In the embodiment of the present disclosure, in order to increase heat dissipation, the fan speed of one, two or more startup stages can be increased, and the corresponding increase ratio can be determined according to the freezer compartment temperature and the ambient temperature.

[0076] Table 3 is a corresponding relationship between the freezing compartment temperature, the ambient temperature and the boost ratio provided by an embodiment of the present disclosure.

[0077]

[0078] Table 3

[0079] If the current freezing compartment temperature is 8° C. and the current ambient temperature is 28° C., according to Table 3, it can be determined that the current increase ratio is 15%, that is, the current fan operating speed can be the current fan speed*(1+15%).

[0080] Of course, in some embodiments, the operating speed of the cooling fan corresponding to the startup phase may need to be increased. For example, the starting speed of the compressor corresponding to the above-mentioned startup phase needs to be reduced, and the operating speed of the fan corresponding to the device needs to be increased. The details will not be elaborated.

[0081] It can be seen that it can not only reduce the heat generated by the compressor, but also increase the speed of the cooling fan, accelerate the heat dissipation of the compressor compartment, further prevent the components of the frequency conversion device in the compressor compartment from overheating, and further improve the operating stability and safety of the compressor and refrigerator.

[0082] In the related art, when the refrigerator is powered on, not only the compressor needs to start and run, but also the refrigeration fan corresponding to the freezer compartment needs to start and run. This may cause a maximum load. In some embodiments of the present disclosure, the start-up and operation of the refrigeration fan can also be delayed. That is, when the current freezer compartment temperature is greater than the first set value, after obtaining the current ambient temperature, it can also include: determining a current delay time that matches the current freezer compartment temperature and the current ambient temperature; when the current start-up and operation time of the refrigerator reaches the current delay time, controlling the refrigeration fan to start and run.

[0083] Table 4 is a correspondence between a freezing compartment temperature, an ambient temperature and a delay time provided by an embodiment of the present disclosure.

[0084]

[0085] Table 4

[0086] If the current freezer compartment temperature is 35°C and the current ambient temperature is 39°C, according to Table 4, it can be determined that the current delay time can be 12 minutes, that is, the refrigeration fan is controlled to start running only when the current startup running time of the refrigerator reaches 12 minutes.

[0087] It can be seen that by delaying the start-up of the refrigeration fan, the maximum load point when the refrigerator is started can be missed, thereby further preventing the components of the frequency conversion device in the compressor compartment from overheating, and further improving the operating stability and safety of the compressor and refrigerator.

[0088] The refrigerator starts running after being powered on, which may be the first time it is powered on, including: the first time the refrigerator is powered on, or the refrigerator is powered on after being in a power-off state for a power-off period exceeding a set period. In addition, the refrigerator may also be powered on and started after defrosting. In some embodiments, when the refrigerator is powered on after defrosting, the starting frequency of a starting stage may be reduced, that is, when it is determined that the refrigerator is powered on after defrosting, the first compressor starting speed corresponding to the first starting stage is obtained, wherein the first starting stage is the starting stage corresponding to the first time interval after power-on; the first compressor starting speed is reduced to obtain the first compressor operating speed, and within the first time interval, the compressor is controlled to operate at the first compressor operating speed. Among them, the first compressor starting speed can be reduced according to a fixed value or a set proportional value.

[0089] In this way, the compressor speed can also be reduced, the heat generated by the compressor can be reduced, and the components of the frequency conversion device in the compressor compartment can be prevented from overheating, thereby improving the operating stability and safety of the compressor and the refrigerator.

[0090] The operation flow is collected into a specific embodiment below to illustrate the refrigerator startup control process provided by the embodiment of the present invention.

[0091] In one embodiment of the present disclosure, the refrigerator stores the corresponding relationships shown in Table 1 and Table 2, and the first set value is -5 degrees Celsius.

[0092] Figure 2 FIG. 1 is a flow chart of a refrigerator startup control method provided by an embodiment of the present disclosure. Figure 2 As shown, the refrigerator startup control process includes:

[0093] Step 201: When the refrigerator is powered on, determine whether it meets the first power-on condition. If so, execute step 202; otherwise, the current speed reduction start ends.

[0094] Among them, if the refrigerator is powered on for the first time, it can be determined that the initial power-on is met, and step 202 is executed; or, if the power outage time recorded by the refrigerator in the power-off state exceeds 8 hours, it can also be determined that the initial power-on is met, and step 202 is executed.

[0095] Step 202: The refrigerator obtains the current freezing compartment temperature F_SNR.

[0096] Step 203: Determine whether F_SNR>-5°C is established. If so, execute step 204; otherwise, this speed reduction start ends.

[0097] Step 204: The refrigerator obtains the current ambient temperature RT.

[0098] Step 205: According to Table 1, the refrigerator determines the current startup phase and the current compressor operating frequency corresponding to the current startup operation duration, and obtains the corresponding current compressor startup speed.

[0099] Step 206: According to Table 2, determine whether the current startup phase is the set startup phase. If yes, execute step 207; otherwise, execute step 209.

[0100] Step 207: According to Table 2, the refrigerator determines the current compressor down speed corresponding to the current freezing compartment temperature F_SNR and the current ambient temperature RT.

[0101] Step 208: The refrigerator determines the difference between the current compressor startup speed and the current compressor reduction speed as the current compressor operation speed. Then the process proceeds to step 210.

[0102] Step 209: The refrigerator determines the current compressor startup speed as the current compressor operation speed. Then the process proceeds to step 210.

[0103] Step 210: In the current startup phase, the refrigerator controls the compressor to run at the current compressor operating speed.

[0104] Step 211: Determine whether the current startup phase is the last startup phase. If yes, the current speed reduction startup ends. Otherwise, return to step 205.

[0105] It can be seen that in this embodiment, when the refrigerator is powered on for the first time and the temperature of the freezer compartment is greater than the first set value, during the startup process of the refrigerator corresponding to different compressor startup speeds in stages, the compressor startup speed corresponding to one or more startup stages of the refrigerator compressor can be reduced according to the freezer compartment temperature and the ambient temperature to obtain the corresponding compressor operating speed, and the corresponding compressor speed control is performed, that is, under the same load, the compressor speed is reduced, the heat generated by the compressor is reduced, and the components of the frequency conversion device in the compressor compartment are prevented from overheating, thereby improving the operating stability and safety of the compressor and the refrigerator.

[0106] In one embodiment of the present disclosure, the first set value is -5 degrees Celsius, and the refrigerator saves the corresponding relationships shown in Table 1, Table 2, Table 3 and Table 4.

[0107] Figure 3FIG. 1 is a flow chart of a refrigerator startup control method provided by an embodiment of the present disclosure. Figure 3 As shown, the refrigerator startup control process includes:

[0108] Step 301: When the refrigerator is powered on, determine whether it is the first power-on condition. If yes, execute step 302; otherwise, execute step 311.

[0109] Step 302: The refrigerator obtains the current freezing compartment temperature F_SNR.

[0110] Step 303: Determine whether F_SNR>-5°C is established. If yes, execute step 304; otherwise, this speed reduction start ends.

[0111] Step 304: The refrigerator obtains the current ambient temperature RT.

[0112] Step 305: According to Tables 2, 3, and 4, the refrigerator determines the set startup phase corresponding to the current freezing compartment temperature and the current ambient temperature and the current compressor reduction speed, determines the corresponding current boost ratio, and determines the corresponding current delay time.

[0113] Step 306: When the current startup operation time reaches the current delay time, the refrigerator controls the refrigeration fan to start running.

[0114] Step 307: According to Table 1, the refrigerator determines the current startup phase and the current compressor operating frequency corresponding to the current startup operation duration, and obtains the corresponding current compressor startup speed, and determines the current fan speed of the cooling fan corresponding to the current startup phase.

[0115] Step 308: When the current startup stage is the set startup stage, the refrigerator determines the difference between the current compressor startup speed and the current compressor decrease speed as the current compressor operating speed, and when the current startup stage is not the set startup stage, the refrigerator determines the current compressor startup speed as the current compressor operating speed, and the refrigerator increases the current fan speed according to the current increase ratio to obtain the current fan operating speed.

[0116] Step 309: In the current startup phase, the refrigerator controls the compressor to operate at the current compressor operating speed, and controls the cooling fan to operate at the current fan operating speed.

[0117] Step 310: Determine whether the current startup phase is the last startup phase. If so, the current speed reduction startup ends. Otherwise, return to step 307.

[0118] Step 306 and steps 307-310 can be executed in parallel.

[0119] Step 311: When the refrigerator is powered on, determine whether the refrigerator meets the requirement of defrosting before powering on. If so, execute step 312; otherwise, this speed reduction start ends.

[0120] Step 312: According to Table 1, the refrigerator obtains the first compressor starting speed corresponding to the starting stage 1, and reduces the first compressor starting speed to obtain the first compressor operating speed.

[0121] For example, according to Table 1, the starting speed of the first compressor is 3480 rpm, and 3480-100=3380 rpm can be determined as the operating speed of the first compressor.

[0122] Step 313: In the startup phase 1, the refrigerator controls the compressor to run at the first compressor operating speed, and continues to start the compressor in stages.

[0123] That is, when the refrigerator is powered on after defrosting, only the compressor starting speed corresponding to the startup stage 1 will be reduced, while the compressor starting speeds in other stages will not change. Moreover, in the process of staged frequency increase of the compressor, the speed of the cooling fan does not need to be increased, and there is no need to delay the operation of the refrigeration fan.

[0124] It can be seen that in this embodiment, not only can the compressor speed be reduced under the same load condition to reduce the heat generated by the compressor and prevent the components of the frequency converter in the compressor compartment from overheating, but also the heat dissipation of the compressor compartment can be accelerated by increasing the speed of the cooling fan, and the maximum load point when the refrigerator is started can be staggered by delaying the start of the refrigeration fan, thereby further preventing the components of the frequency converter in the compressor compartment from overheating and further improving the operating stability and safety of the compressor and the refrigerator.

[0125] According to the above process for refrigerator startup control, a device for refrigerator startup control can be constructed.

[0126] Figure 4 Schematic diagram of a refrigerator startup control device provided by an embodiment of the present disclosure. The refrigerator is equipped with a water-washing fresh air module, such as Figure 4 As shown, the refrigerator startup control device 400 includes: a first acquisition module 410, a second module 420 and a first control module 420.

[0127] The first acquisition module 410 is configured to acquire the current freezing compartment temperature when it is determined that the refrigerator is powered on for the first time.

[0128] The second acquisition module 420 is configured to acquire the current ambient temperature when the current freezing compartment temperature is greater than the first set value.

[0129] The first control module 430 is configured to reduce the compressor starting speed corresponding to one or more starting stages of the refrigerator compressor according to the current freezer compartment temperature and the current ambient temperature, obtain the corresponding compressor operating speed, and perform corresponding compressor speed control.

[0130] In some embodiments, it also includes: a first determination module, which is configured to determine that the conditions for the initial power-on of the refrigerator are met when the refrigerator is powered on for the first time; and when the power-off time of the refrigerator exceeds the set time, if the refrigerator is powered on, determine that the conditions for the initial power-on of the refrigerator are met.

[0131] In some embodiments, the first control module is specifically configured to obtain the current compressor starting speed of the compressor corresponding to the current starting stage, wherein each starting stage of the refrigerator compressor is divided according to a set time interval, and, when the current starting stage is the set starting stage, determine the current compressor decreasing speed that matches the current freezer compartment temperature and the current ambient temperature, and determine the difference between the current compressor starting speed and the current compressor decreasing speed as the current compressor operating speed.

[0132] In some embodiments, it also includes: a second control module, configured to obtain the current fan speed of the cooling fan corresponding to the current startup stage, wherein each startup stage of the refrigerator compressor is divided according to a set time interval; and determine a current boost ratio that matches the current freezer compartment temperature and the current ambient temperature, and boost the current fan speed according to the current boost ratio to obtain the current fan operating speed, and perform corresponding cooling fan speed control.

[0133] In some embodiments, it also includes: a third control module, which is configured to determine a current delay time that matches the current freezer compartment temperature and the current ambient temperature; when the current startup operation time of the refrigerator reaches the current delay time, control the refrigeration fan to start running.

[0134] In some embodiments, it also includes: a fourth control module, which is configured to obtain a first compressor starting speed corresponding to a first starting stage when it is determined that the refrigerator is powered on after defrosting, wherein the first starting stage is a starting stage corresponding to the first time interval after power-on; reduce the first compressor starting speed to obtain a first compressor operating speed, and control the compressor to operate at the first compressor operating speed within the first time interval.

[0135] The refrigerator startup control process used in the refrigerator startup control device is further described below in conjunction with the embodiments.

[0136] In this embodiment, the first set value is -5 degrees Celsius, and the refrigerator saves the corresponding relationships shown in Table 1, Table 2, Table 3 and Table 4.

[0137] Figure 5 Schematic diagram of a refrigerator startup control device provided by an embodiment of the present disclosure. Figure 5 As shown, the refrigerator startup control device 400 includes: a first acquisition module 410, a second acquisition module 420, a first control module 430, a first determination module 440, a second control module 450, a third control module 460 and a fourth control module 470.

[0138] In this embodiment, if the refrigerator is in a power-off state for a power-off time of >8 hours and the refrigerator is powered on, the first determination module 440 may determine that the first power-on condition is met, and the first acquisition module 410 acquires the current freezer compartment temperature F_SNR.

[0139] When F_SNR>-5°C, the second acquisition module 420 obtains the current ambient temperature RT of the refrigerator. Therefore, the first control module 430 can determine the current startup phase and the current compressor operation frequency corresponding to the current startup operation duration according to Table 1, and obtain the corresponding current compressor startup speed, and can determine the set startup phase and the current compressor drop speed corresponding to the current freezing compartment temperature and the current ambient temperature according to Table 2, and then, when the current startup phase is the set startup phase, the first control module 430 can determine the difference between the current compressor startup speed and the current compressor drop speed as the current compressor operation speed, and when the current startup phase is not the set startup phase, the first control module 430 can determine the current compressor startup speed as the current compressor operation speed; thus, the first control module 430 controls the compressor to operate at the corresponding compressor operation speed in each startup phase.

[0140] Moreover, when F_SNR>-5°C, after the second acquisition module 420 refrigerator obtains the current ambient temperature RT, the second control module 450 can obtain the fan speed of the cooling fan corresponding to each startup stage, and can determine the current increase ratio that matches the current freezer compartment temperature and the current ambient temperature according to Table 3, and increase the speed of each fan according to the current increase ratio to obtain the corresponding fan operating speed, and perform corresponding cooling fan speed control.

[0141] Similarly, when F_SNR>-5°C, after the second acquisition module 420 refrigerator obtains the current ambient temperature RT, the third control module 460 can determine the current delay time that matches the current freezer compartment temperature and the current ambient temperature according to Table 4, and control the refrigeration fan to start running when the current startup running time of the refrigerator reaches the current delay time.

[0142] If the refrigerator is powered on after defrosting, that is, the first determination module 440 determines that the refrigerator is powered on after defrosting, the fourth control module 470 obtains the first compressor starting speed corresponding to the starting stage 1 according to Table 1, reduces the first compressor starting speed, obtains the first compressor operating speed, and starts stage 1, controls the compressor to run at the first compressor operating speed, and continues to start the compressor in stages.

[0143] It can be seen that in this embodiment, the device for refrigerator startup control can reduce the compressor speed and the heat generated by the compressor under the same load condition to prevent the components of the frequency conversion device in the compressor compartment from overheating, and can also speed up the heat dissipation of the compressor compartment by increasing the speed of the cooling fan, and stagger the maximum load point when the refrigerator is started by delaying the start of the refrigeration fan, thereby further preventing the components of the frequency conversion device in the compressor compartment from overheating and further improving the operating stability and safety of the compressor and the refrigerator.
