At present, the noise of refrigerators on the market generally meets the standard specifications. However, for users, during the use of the refrigerator, they generally require the noise of the refrigerator to be lower than the standard specifications.

[0003] At present, most noise reduction measures for refrigerators are achieved through hardware technology, such as adding shock-absorbing blocks or sound insulation cotton, etc. However, the noise reduction effect of the above methods is not good, and it is difficult to meet the user's requirements for refrigerator noise.

[0013] In this embodiment, the refrigeration system of the refrigerator includes a compressor compartment and an evaporator, and a compressor, an air-cooled condenser, a fan, a direct-cooled condenser and a sound pressure sensor are arranged in the compressor compartment. The compressor is used to provide power for the refrigeration cycle of the refrigerator, the evaporator is used to provide cold capacity for the refrigerator, the air-cooled condenser and the direct-cooled condenser are used to dissipate heat from the refrigerant of the compressor, the fan is used to dissipate heat for the air-cooled condenser when the air-cooled condenser is working, so as to improve the condensation effect of the condenser, and the sound pressure sensor is used to detect the environmental noise of the environment where the refrigerator is located or the noise of the compressor compartment. The control component is configured to obtain a first noise value in the compressor compartment through the sound pressure sensor in the current refrigeration cycle when the refrigeration system starts to run for a first preset time, determine the target condenser according to the first noise value and the second noise value, the second noise value is the environmental noise value of the environment where the refrigerator is located when the refrigeration system stops running, and control the target condenser to continue to run in the current refrigeration cycle, and if the target condenser includes an air-cooled condenser, turn on the fan. This application is based on the fact that the noise generated by the operation of a direct-cooling condenser and an air-cooling condenser is different. According to the ambient noise when the refrigeration system stops running and the noise of the compressor compartment, the running condenser is determined to achieve the effect of reducing noise.

[0014] In some embodiments of the present application, the control component is configured as follows:

[0015] Determine a first condenser according to the first noise value and the second noise value;

[0016] If the first condenser is the direct cooling condenser, after controlling the first condenser to operate for a second preset time, obtaining a first energy consumption of the refrigerator within the second preset time;

[0017] If the first energy consumption is less than a preset energy consumption, determining that the target condenser is the direct cooling condenser;

[0018] If the first energy consumption is greater than the preset energy consumption, the target condenser is determined to be the direct cooling condenser and the air cooling condenser.

[0019] In this embodiment, when the condenser is preliminarily determined to be a direct cooling condenser, the energy consumption of the refrigerator can be considered, and then the final target condenser is determined based on the energy consumption, so as to achieve the purpose of energy saving.

[0020] In some embodiments of the present application, the control component is configured as follows:

[0021] determining whether the first noise value is less than a third noise value, wherein the third noise value is determined based on the second noise value;

[0022] If yes, it is determined that the first condenser is the direct-cooling condenser and the air-cooling condenser;

[0023] If not, it is determined that the first condenser is the direct cooling condenser.

[0024] In this embodiment, it can be determined whether the first noise value meets the preset conditions. If so, it means that the noise is relatively small, and a direct cooling condenser and an air cooling condenser can be used to cool the refrigerant. If not, it means that the noise is relatively large, and a direct cooling condenser can be used to achieve noise reduction.

[0025] In some embodiments of the present application, the third noise value is the sum of the fourth noise value and the fifth noise value;

[0026] Among them, the fourth noise value is the difference between the preset standard noise value of the refrigerator and the envelope area of ​​the refrigerator, and the fifth noise value is the difference between the ambient noise value of the experimental environment of the refrigerator before leaving the factory and the second noise value.

[0027] In this embodiment, the third noise value is determined based on the second noise value, the preset standard noise value of the refrigerator, the envelope area of ​​the refrigerator, and the ambient noise value of the experimental environment of the refrigerator before leaving the factory, which can improve the accuracy of noise judgment.

[0028] In some embodiments of the present application, the compressor compartment further includes a temperature sensor, and the temperature sensor is used to detect the temperature in the compressor compartment;

[0032] If not, the air-cooled condenser and the fan are controlled to be turned off;

[0033] If so, the direct cooling condenser and the air cooling condenser are controlled to continue to operate in the current refrigeration cycle.

[0034] In this embodiment, if the target condenser is a direct-cooled condenser and an air-cooled condenser, it can be considered whether the temperature of the compressor compartment is high. If so, it is necessary to keep the air-cooled condenser running to achieve cooling. If not, the air-cooled condenser and the fan can be turned off to reduce noise.

[0035] In some embodiments of the present application, the control component is further configured to:

[0036] After controlling the air-cooled condenser and the fan to be turned off, obtaining a second energy consumption of the direct-cooled condenser and the air-cooled condenser for a third preset time period;

[0037] When the direct cooling condenser operates for a fourth preset time, obtaining a third energy consumption of the refrigerator within the fourth preset time, the fourth preset time being equal to the third preset time;

[0039] If yes, turning on the air-cooled condenser and the fan;

[0040] If not, the direct cooling condenser is controlled to continue to operate until the refrigeration of the current refrigeration cycle is completed.

[0041] In this embodiment, if the temperature of the compressor compartment is high, after turning off the air-cooled condenser, it can be determined whether the energy consumption of the direct-cooled condenser has increased compared with the energy consumption of the direct-cooled condenser and the air-cooled condenser. If it has increased, the air-cooled condenser and the fan can be turned on to reduce the energy consumption of the refrigerator. If it has not increased, the direct cooling can be kept running to reduce noise while ensuring that the energy consumption is not too high.

[0042] In some embodiments of the present application, the air-cooled condenser and the direct-cooled condenser are connected in series via a pipeline;

[0043] The compressor compartment further comprises a solenoid valve, an inlet of the solenoid valve is connected to the compressor via a pipeline, a first outlet of the solenoid valve is connected to the air-cooled condenser via a pipeline, and a second outlet of the solenoid valve is connected to the direct-cooled condenser via a pipeline;

[0044] The control component is configured to:

[0045] When the air-cooled condenser is controlled to be turned on, the inlet of the solenoid valve and the first outlet are controlled to be connected so that the refrigerant flows to the air-cooled condenser and the direct-cooled condenser;

[0046] When the air-cooled condenser is controlled to be closed, the inlet of the solenoid valve and the second outlet are controlled to be connected so that the refrigerant flows to the direct-cooled condenser.

[0047] In this embodiment, the control component can open or close the air-cooled condenser by controlling the outlet of the solenoid valve.

[0048] In some embodiments of the present application, the control component is configured as follows:

[0049] When the refrigeration system stops refrigeration, obtaining the second noise value of the environment where the refrigerator is located through the sound pressure sensor;

[0050] The second noise value is stored.

[0051] In this embodiment, before the current refrigeration cycle, when the refrigeration system stops refrigeration, a second noise value of the environment where the refrigerator is located can be obtained through a sound pressure sensor, and the noise value can be stored for determining the target condenser in a subsequent refrigeration cycle.

[0052] In a second aspect, the present application provides a noise reduction method for a refrigerator, the refrigerator comprising:

[0053] A box body, wherein a storage room is arranged in the box body;

[0054] The refrigeration system arranged in the box body includes a compressor compartment and an evaporator, and a compressor, an air-cooled condenser, a fan, a direct-cooled condenser and a sound pressure sensor are arranged in the compressor compartment; the compressor is used to provide power for the refrigeration cycle of the refrigerator; the evaporator is used to provide cold capacity for the refrigerator; the air-cooled condenser and the direct-cooled condenser are used to dissipate heat for the refrigerant from the compressor; the fan is used to dissipate heat for the air-cooled condenser when the air-cooled condenser is working, so as to improve the condensation effect of the air-cooled condenser; the sound pressure sensor is used to detect the ambient noise of the environment where the refrigerator is located or the noise of the compressor compartment;

[0055] The method comprises:

[0056] In the current refrigeration cycle, when the refrigeration system starts to run for a first preset time, a first noise value in the compressor compartment is obtained by the sound pressure sensor;

[0057] Determine a target condenser according to the first noise value and the second noise value, wherein the second noise value is an environmental noise value of an environment in which the refrigerator is located when the refrigeration system stops operating;

[0060] In this embodiment, in the current refrigeration cycle, when the refrigeration system starts to run for the first preset time, the first noise value in the compressor compartment is obtained through the sound pressure sensor, and the target condenser is determined according to the first noise value and the second noise value. The second noise value is the environmental noise value of the environment where the refrigerator is located when the refrigeration system stops running, and the target condenser is controlled to continue running in the current refrigeration cycle. If the target condenser includes an air-cooled condenser, the fan is turned on. This application is based on the fact that the noise generated by the operation of the direct-cooling condenser and the air-cooling condenser is different. According to the environmental noise when the refrigeration system stops running and the noise of the compressor compartment, the running condenser is determined, and the effect of reducing noise can be achieved.

[0077] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0078] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0079] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0080] At present, most noise reduction measures for refrigerators are achieved through hardware technology, such as adding shock-absorbing blocks or sound insulation cotton, etc. However, the noise reduction effect of the above methods is not good, and it is difficult to meet the user's requirements for refrigerator noise. Therefore, how to further achieve noise reduction to improve user experience is an urgent problem to be solved.

[0081] Generally, with the improvement of refrigerator noise standards, users have lower requirements for refrigerator noise than the standard. For example, users require refrigerator noise to be below 29dB (decibels). In this case, the human ear can basically not hear the noise generated by the refrigerator. Therefore, in a home environment, the noise of the refrigerator should be lower than the ambient noise (it can be higher than the ambient noise when the refrigerator is defrosting). However, most of the current refrigerators are difficult to meet the above requirements.

[0082] Therefore, the present application provides a refrigerator. Based on the different noises generated by the operation of a direct cooling condenser and an air cooling condenser, the operating condenser is determined according to the ambient noise when the refrigeration system stops running and the noise of the compressor compartment, thereby achieving the effect of reducing noise.

[0083] The technical solution of the present application is described in detail below in conjunction with specific embodiments. The following specific embodiments can be combined with each other or exist independently. The same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0084] Figure 1 A schematic diagram of the structure of a refrigerator provided in this application, such as Figure 1 As shown, the refrigerator includes a box body 101, a storage room (not shown) arranged in the box body 101, a refrigeration system 102 arranged in the box body 101, and a control component 103 arranged in the box body 101. The storage room may include a refrigerating room, a freezing room, a temperature-changing room, and the like.

[0085] The refrigeration system 102 includes a compressor compartment 104 and an evaporator 105 , and a compressor 41 , an air-cooled condenser 42 , a fan 43 , a direct-cooled condenser 44 and a sound pressure sensor 45 are arranged in the compressor compartment 104 .

[0086] The compressor 41 is used to provide power for the refrigeration cycle of the refrigerator 10, and the evaporator 105 is used to provide cooling capacity for the refrigerator 101. The air-cooled condenser 42 and the direct-cooled condenser 44 are used to dissipate heat for the refrigerant from the compressor 41. It can be understood that the refrigerant from the compressor 41 is a high-temperature and high-pressure refrigerant. The fan 43 is used to dissipate heat for the air-cooled condenser 42 when the air-cooled condenser 42 is working, so as to improve the condensation effect of the air-cooled condenser 42. The sound pressure sensor 45 is used to detect the ambient noise of the environment where the refrigerator is located or the noise of the compressor compartment 104.

[0087] The control component 103 is configured to:

[0088] In the current refrigeration cycle, when the refrigeration system 102 starts to run for the first preset time, the first noise value in the compressor compartment 104 is obtained through the sound pressure sensor 45, and the target condenser is determined based on the first noise value and the second noise value. The second noise value is the ambient noise value of the environment where the refrigerator is located when the refrigeration system 102 stops running. The target condenser is controlled to continue running in the current refrigeration cycle. If the target condenser includes an air-cooled condenser 42, the fan 43 is turned on.

[0089] In one possible implementation, Figure 2 This is a structural schematic diagram of another refrigerator provided in an embodiment of the present application, wherein the compressor compartment 104 also includes a temperature sensor 46 , and the temperature sensor 46 is used to detect the temperature inside the compressor compartment 104 .

[0090] For example, the compressor 41, the air-cooled condenser 42, the fan 43, and the direct-cooled condenser 44 may be connected by pipelines. Figure 3 A structural schematic diagram of a compressor compartment 104 is provided in an embodiment of the present application, wherein the compressor compartment 104 also includes a solenoid valve 47, an inlet of the solenoid valve 47 is connected to the compressor 41 through a pipeline, a first outlet of the solenoid valve 47 is connected to the air-cooled condenser 42 through a pipeline, and a second outlet of the solenoid valve 47 is connected to the direct-cooled condenser 44 through a pipeline.

[0091] When the first outlet is connected and the second outlet is not connected, the high-temperature and high-pressure refrigerant output by the compressor 41 can be discharged into the air-cooled condenser 42 and the direct-cooled condenser 44, that is, it is first preliminarily cooled in the air-cooled condenser 42 and then discharged into the direct-cooled condenser 44 for further cooling, thereby discharging normal temperature and high-pressure refrigerant.

[0092] When the second outlet is connected and the first outlet is not connected, the high-temperature and high-pressure refrigerant output by the compressor 41 can be discharged into the direct-cooling condenser 44, and the high-temperature and high-pressure refrigerant is cooled only by the direct-cooling condenser 44. It can be understood that the fan 43 is also in a stopped state at this time.

[0093] After cooling, the high-temperature and high-pressure refrigerant becomes a liquid at room temperature and pressure. The liquid at room temperature and pressure is further throttled and depressurized to become steam at room temperature and pressure. The steam at room temperature and pressure begins to absorb heat and vaporize in the evaporator 105, which not only reduces the temperature of the evaporator 105 and its surroundings, but also turns the refrigerant into a low-temperature and low-pressure gas. The refrigerant coming out of the evaporator 105 can return to the compressor 41 again, thereby achieving refrigeration. It should be understood that Figure 3 The pipeline connection between the central direct cooling condenser 44 and the evaporator 105, and the pipeline connection between the evaporator 105 and the compressor 41 also include other structural elements, such as a drying filter, an electric switching valve and capillaries, etc., which are not shown in the figure.

[0094] It should be understood that the control component 103 can be electrically connected to the solenoid valve 47, the temperature sensor 46, the sound pressure sensor 45 and the fan 43 to achieve control of the solenoid valve 47, the temperature sensor 46 and the sound pressure sensor 45. Specifically, the control component 103 can control the opening or closing of the inlet and outlet of the solenoid valve 47, the control component 103 can control the temperature sensor 46 to detect the temperature of the compressor compartment 104 and control the sound pressure sensor 45 to detect the noise of the compressor compartment 104 or the environment where the refrigerator is located, and the control component 103 can control the fan 43 to be turned on or off.

[0095] In one possible implementation, Figure 4 A schematic diagram of a compressor compartment 104 provided in an embodiment of the present application, the sound pressure sensor 45 can be arranged on the top of the compressor compartment 104, and the temperature sensor 46 can be arranged on the side wall of the compressor compartment 104. The sound pressure sensor 45 and the temperature sensor 46 can also be arranged at other positions of the compressor compartment 104, and the present application does not limit this.

[0096] In a possible implementation, the control component 103 may be a microcontroller unit (MCU).

[0097] Based on the above refrigerator, Figure 5 A flowchart of a noise reduction method for a refrigerator provided in an embodiment of the present application is provided. The method can be executed by a control component of the refrigerator, such as Figure 5 As shown, the method comprises the following steps:

[0098] S501. In a current refrigeration cycle, when the refrigeration system starts to run for a first preset time, a first noise value in the compressor compartment is obtained through a sound pressure sensor.

[0099] In the current refrigeration cycle, when it is detected that the refrigeration system starts to start, the control component can start timing. When the running time after the refrigeration system starts reaches a first preset time, the first noise value in the compressor compartment can be obtained through the sound pressure sensor.

[0100] It can be understood that the current refrigeration cycle refers to the cycle from when the refrigeration system starts to when the refrigeration system stops refrigeration.

[0101] Exemplarily, when the running time of the refrigeration system after startup reaches a first preset time, it may be the moment when the speed of the compressor increases from 0 to a stable speed, that is, the speed of the compressor runs at the stable speed for the subsequent time in the current refrigeration cycle.

[0102] S502: Determine a target condenser according to a first noise value and a second noise value, wherein the second noise value is an environmental noise value of an environment where the refrigerator is located when the refrigeration system stops operating.

[0103] The control component may obtain a second noise value, and then determine a target condenser according to the first noise value and the second noise value.

[0104] Exemplarily, the control component may obtain the second noise value in the following manner:

[0105] When the refrigeration system stops refrigeration, the control component can obtain the second noise value of the environment where the refrigerator is located through the sound pressure sensor. For example, the control component can send a refrigeration detection command to the sound pressure sensor, so that the sound pressure sensor detects the noise value of the environment where the refrigerator is located when receiving the detection command, and then the control component can receive the output signal sent by the sound pressure sensor, and determine the second noise value based on the output signal.

[0106] In one possible implementation, the control component can send a detection instruction to the sound pressure sensor at preset time intervals when the refrigeration system stops refrigeration. For example, the preset time period can be one week, one month or half a year, so that the refrigerator can update the noise value of the environment where the refrigerator is located in a timely manner, thereby avoiding large changes in the noise value of the environment where the refrigerator is located due to the user adding new home appliances.

[0107] In another possible implementation, since the noise value of the environment where the refrigerator is located will change at night and during the day, the control component can send detection instructions to the sound pressure sensor at a certain time at night and a certain time during the day, so that the sound pressure sensor can detect the noise value of the environment where the refrigerator is located at night and during the day. That is to say, the refrigerator can update the noise value of the environment where the refrigerator is located at a certain time at night and a certain time during the day every day.

[0108] S503: Control the target condenser to continue operating in the current refrigeration cycle.

[0109] After determining the target condenser, the control component can control the target condenser to continue operating in the current refrigeration cycle. Specifically, the control component can control the state of the first outlet or the second outlet of the solenoid valve so that the target condenser can continue to cool the high-temperature and high-pressure refrigerant in the current refrigeration cycle.

[0110] S504: If the target condenser includes an air-cooled condenser, turn on the fan.

[0111] If the target condenser includes an air-cooled condenser, the control component can turn on the air fan so that the fan cools the air-cooled condenser, further improving the condensation effect of the air-cooled condenser.

[0112] In this embodiment, in the current refrigeration cycle, when the refrigeration system starts to run for the first preset time, the first noise value in the compressor compartment is obtained by the sound pressure sensor, and the target condenser is determined according to the first noise value and the second noise value. The second noise value is the environmental noise value of the environment where the refrigerator is located when the refrigeration system stops running, and the target condenser is controlled to continue running in the current refrigeration cycle. If the target condenser includes an air-cooled condenser, the fan is turned on. This application is based on the difference in noise generated by the operation of a direct-cooled condenser and an air-cooled condenser. According to the environmental noise when the refrigeration system stops running and the noise of the compressor compartment, the running condenser is determined, and the effect of reducing noise can be achieved.

[0113] Next, how the control component determines the target condenser according to the first noise value and the second noise value is described in detail.

[0114] In a possible implementation, the control component may directly determine the target condenser according to the first noise value and the second noise value, thereby controlling the target condenser to continue operating in the current refrigeration cycle.

[0115] In another possible implementation, the control component may consider the energy consumption of the refrigerator when determining the target condenser according to the first noise value and the second noise value, so that the energy consumption of the refrigerator will not be too high when reducing noise. Specifically, this may be implemented in the following manner:

[0116] Figure 6 A flowchart of another refrigerator noise reduction method provided in an embodiment of the present application is provided. The method can be executed by a control component of the refrigerator, such as Figure 6 As shown, the method comprises the following steps:

[0117] S601. Determine a first condenser according to a first noise value and a second noise value.

[0118] Before determining the target condenser, the control component can determine a preliminary condenser, i.e., the first condenser, based on the first noise value and the second noise value, so as to consider the energy consumption of the refrigerator based on the first condenser, thereby achieving the purpose of energy saving when the refrigerator reduces noise.

[0119] S602: If the first condenser is a direct cooling condenser, after controlling the first condenser to operate for a second preset time, obtain a first energy consumption of the refrigerator within the second preset time.

[0120] S603: Determine whether the first energy consumption is less than the preset energy consumption.

[0121] If the first energy consumption is less than the preset energy consumption, it means that the energy consumption of the direct cooling condenser during the second preset time does not exceed the preset energy consumption, that is, the energy consumption is not high. Then it can be determined that the target condenser is a direct cooling condenser, that is, the high-temperature and high-pressure refrigerant continues to be cooled by the direct cooling condenser.

[0122] If the first energy consumption is above the preset energy consumption, it means that the energy consumption of the direct cooling condenser running for the second preset time exceeds the preset energy consumption, that is, the energy consumption is high. Then it can be determined that the target condenser is a direct cooling condenser and an air-cooled condenser. The start-up of the air-cooled condenser and the fan can reduce the temperature of the compressor compartment, thereby reducing energy consumption.

[0123] The second preset time period may be the time period required for the high-temperature and high-pressure refrigerant to be completely switched to the direct-cooling condenser.

[0124] If yes, execute S604, if no, execute S605.

[0125] S604: Determine that the target condenser is a direct cooling condenser.

[0126] S605. Determine whether the target condenser is a direct cooling condenser or an air cooling condenser.

[0127] In this embodiment, when the condenser is preliminarily determined to be a direct cooling condenser, the energy consumption of the refrigerator can be considered, and then the final target condenser is determined based on the energy consumption, so as to achieve the purpose of energy saving.

[0128] Next, how to determine the first condenser according to the first noise value and the second noise value is described in detail:

[0129] Figure 7 A flowchart of another refrigerator noise reduction method provided in an embodiment of the present application is provided. The method can be executed by a control component of the refrigerator, such as Figure 7 As shown, the method comprises the following steps:

[0130] S701. In the current refrigeration cycle, when the refrigeration system starts to run for a first preset time, a first noise value in the compressor compartment is obtained through a sound pressure sensor.

[0131] S702: Determine whether the first noise value is less than the third noise value.

[0132] If so, it means that the noise value is small, and the high-temperature and high-pressure refrigerant can continue to be cooled by the direct-cooling condenser and the air-cooling condenser, and execute S703. If not, it means that the noise value is large, and the air-cooling condenser can be turned off, that is, the high-temperature and high-pressure refrigerant can be cooled by the direct-cooling condenser, and execute S704.

[0133] The third noise value is determined based on the second noise value. Exemplarily, the third noise value may be determined in the following manner:

[0134] The fifth noise value is determined according to the second noise value. Specifically, the fifth noise value can be the difference between the ambient noise value and the second noise value of the experimental environment of the refrigerator before leaving the factory. It can be understood that the experimental environment can be a semi-silent environment, that is, the ambient noise value is less than the second noise value. Then, the third noise value is determined according to the fourth noise value and the fifth noise value, that is, the third noise value is the sum of the fourth noise value and the fifth noise value, wherein the fourth noise value can be the difference between the preset standard noise value of the refrigerator and the envelope area of ​​the refrigerator. The preset standard noise value is the standard noise value of the noise generated by the refrigerator when it is refrigerated during production. That is to say, the noise generated by the refrigerator needs to be below the standard noise value, and the envelope area can be determined according to the length, width and height of the refrigerator.

[0135] The third noise value is determined based on the second noise value, the preset standard noise value of the refrigerator, the envelope area of ​​the refrigerator, and the environmental noise value of the experimental environment of the refrigerator before leaving the factory, which can improve the accuracy of noise judgment.

[0136] S703: Determine whether the first condenser is a direct cooling condenser or an air cooling condenser.

[0137] S704: Determine that the first condenser is a direct cooling condenser.

[0138] In this embodiment, it can be determined whether the first noise value meets the preset conditions. If so, it means that the noise is relatively small, and a direct cooling condenser and an air cooling condenser can be used to cool the high-temperature and high-pressure refrigerant. If not, it means that the noise is relatively large, and a direct cooling condenser can be used to achieve noise reduction.

[0139] After controlling the target condenser to continue running, the condenser can be controlled again based on the temperature of the compressor compartment, thereby ensuring that the temperature of the compressor compartment does not increase due to noise reduction, thereby ensuring normal refrigeration of the refrigerator.

[0140] Figure 8 A flowchart of another refrigerator noise reduction method provided in an embodiment of the present application is provided. The method can be executed by a control component of the refrigerator, such as Figure 8 As shown, the method comprises the following steps:

[0141] S801. If the target condenser is a direct-cooling condenser or an air-cooling condenser, a first temperature value of the compressor compartment is obtained through a temperature sensor.

[0142] Specifically, after determining that the target condenser is a direct-cooling condenser and an air-cooling condenser, the direct-cooling condenser and the air-cooling condenser may be controlled to execute a third preset time period, and then the first temperature value of the compressor compartment may be obtained.

[0143] S802: Determine whether the first temperature value is greater than a preset temperature value.

[0144] If the first temperature value is greater than the preset temperature value, it means that the temperature of the compressor compartment is relatively high at this time, and the air-cooled condenser and the fan can be kept running to achieve cooling, then S804 is executed.

[0145] If the first temperature value is not greater than the preset temperature value, it means that the temperature of the compressor compartment is normal at this time, and the air-cooled condenser and the fan can be turned off to reduce noise, and S803 can be executed.

[0146] S803, control the air-cooled condenser and fan to shut down.

[0147] S804: Control the direct cooling condenser and the air cooling condenser to continue to operate in the current refrigeration cycle.

[0148] In this embodiment, if the target condenser is a direct-cooled condenser and an air-cooled condenser, it can be considered whether the temperature of the compressor compartment is high. If so, it is necessary to keep the air-cooled condenser running to achieve cooling. If not, the air-cooled condenser and the fan can be turned off to reduce noise.

[0149] In the above embodiment, after determining the condenser that continues to operate in the current refrigeration cycle based on the temperature of the compressor compartment, if the condenser that continues to operate is a direct cooling condenser, that is, after turning off the air-cooled condenser and the fan, the following method can be used to achieve the goal of not excessively high energy consumption of the refrigerator while reducing noise.

[0150] Fig. 9 A flowchart of another refrigerator noise reduction method provided in an embodiment of the present application is provided. The method can be executed by a control component of the refrigerator, such as Fig. 9 As shown, the method comprises the following steps:

[0151] S901. After controlling the air-cooled condenser and the fan to be turned off, obtaining a second energy consumption of the direct-cooled condenser and the air-cooled condenser for a third preset operation time.

[0152] S902: When the direct cooling condenser operates for a fourth preset time period, obtaining a third energy consumption of the refrigerator within the fourth preset time period.

[0153] The third energy consumption is the energy consumption within a fourth preset time period after the air-cooled condenser and the fan are turned off.

[0154] Among them, the fourth preset time length is equal to the third preset time length. It should be understood that the first preset time length, the second preset time length, the third preset time length and the fourth preset time length are all shorter than the time length corresponding to the current refrigeration cycle. In order to clearly show the position of each preset time length in the current refrigeration cycle, Fig.10 Schematic diagram of the current refrigeration cycle of the present application example, Δt1 is the first preset time length, Δt2 is the second preset time length, Δt3 is the third preset time length, Δt4 is the fourth preset time length, it can be understood that, Fig.10The sizes of the first preset time length, the second preset time length, the third preset time length and the fourth preset time length are all examples, the third preset time length and the fourth preset time length are equal, and this application does not limit the size of each time length.

[0155] S903: According to the second energy consumption and the third energy consumption, determine whether the energy consumption of the refrigerator increases after the air-cooled condenser and the fan are turned off.

[0156] If so, the air-cooled condenser and the fan can be turned on to reduce the energy consumption of the refrigerator, and then S904 is executed. If not, the direct cooling condenser can be kept running, that is, the air-cooled condenser and the fan are not turned on to reduce noise while ensuring that the energy consumption is not too high, and then S905 is executed.

[0157] Specifically, when the third energy consumption is greater than the second energy consumption, it can be determined that there is an increase, and when the third energy consumption is less than or equal to the second energy consumption, it can be determined that there is no increase.

[0158] S904. Turn on the air-cooled condenser and fan.

[0159] If the energy consumption of the refrigerator increases, the air-cooled condenser and the fan can be turned on, and the air-cooled condenser and the direct-cooled condenser can be controlled to continue running until the current refrigeration cycle is completed.

[0160] S905. Control the direct cooling condenser to continue to operate until the current refrigeration cycle is completed.

[0161] In this embodiment, if the temperature of the compressor compartment is high, after turning off the air-cooled condenser, it can be determined whether the energy consumption of the direct-cooled condenser has increased compared with the energy consumption of the direct-cooled condenser and the air-cooled condenser. If it has increased, the air-cooled condenser and the fan can be turned on to reduce the energy consumption of the refrigerator. If it has not increased, the direct cooling can be kept running to reduce noise while ensuring that the energy consumption is not too high.
