[0002] To ensure proper cold air circulation inside the refrigerator, an axial fan needs to be installed in the evaporator of the freezer compartment to ensure efficient delivery of cold air to the refrigerator or variable temperature compartment.

[0050] Figure 1 An embodiment of this application provides a refrigerator, comprising:

[0051] A refrigeration fan unit, used for supplying cold energy to a first compartment, includes one or more refrigeration fans; a refrigeration fan unit, used for supplying cold energy to a second compartment, includes one or more refrigeration fans; a refrigeration unit, used for providing and supplying cold energy; the refrigeration unit includes an evaporator and a compressor; a controller, connected to the refrigeration fan unit, the refrigeration fan unit, and the refrigeration unit respectively, is used to control the duty cycle of the refrigeration fan unit and the refrigeration fan unit and the operating speed of the compressor in several operating modes.

[0052] In one possible implementation, the controller is also configured to, in response to a first mode operation command, control the refrigeration fan unit, the cold storage fan unit, and the compressor to operate intermittently according to a preset mode.

[0053] In this mode, the controller will independently control the refrigeration fan unit and compressor, causing them to operate intermittently according to a predetermined periodic pattern. This periodic operation strategy helps optimize the refrigerator's energy consumption while ensuring that the temperatures of the refrigerator and freezer compartments remain at the user-set levels. Intermittent operation helps maintain stable compartment temperatures, avoiding overcooling or temperature fluctuations caused by continuous operation.

[0054] In one possible implementation, the system further includes: a first temperature sensor disposed in the first compartment for collecting the temperature of the first compartment; and a second temperature sensor disposed in the second compartment for collecting the temperature of the second compartment; the controller is further configured to respond to a second mode operation command, control the refrigeration fan unit to operate in a manner matching the second mode according to the temperature of the first compartment, control the refrigerator fan unit to operate in a manner matching the second mode according to the temperature of the second compartment, and control the compressor to operate in a manner matching the second mode.

[0055] In one possible implementation, the controller is further configured to, in response to a second mode operation command, control the refrigeration fan unit to operate in a manner matching the second mode according to the first compartment temperature, control the refrigerator fan unit to operate in a manner matching the second mode according to the second compartment temperature, and control the compressor to operate in a manner matching the second mode, including:

[0056] Based on the fact that the temperature of the first compartment is within the set freezing range and the temperature of the second compartment is within the set refrigeration range, the operation of the refrigeration fan unit is controlled according to the first freezing duty cycle, and the operation of the refrigeration fan unit is controlled according to the first refrigeration duty cycle, so that the operating speed of the compressor is controlled to the first speed.

[0057] Based on the condition that the temperature of the first compartment is higher than a set first freezing threshold, and / or the temperature of the second compartment is higher than a set first refrigeration threshold, the operation of the refrigeration fan unit is controlled according to a second freezing duty cycle, which is obtained by adjusting the first freezing duty cycle; the operating frequency corresponding to the second freezing duty cycle is higher than the operating frequency of the first freezing duty cycle; the operation of the refrigeration fan unit is controlled according to a second refrigeration duty cycle, which is obtained by adjusting the first refrigeration duty cycle; the operating frequency corresponding to the second refrigeration duty cycle is higher than the operating frequency of the first refrigeration duty cycle; the operating speed of the compressor is controlled to a second speed, which is obtained by adjusting the first speed; the second speed is higher than the first speed.

[0058] By installing temperature sensors and controllers in the first compartment (freezer) and the second compartment (refrigerator), flexible control of the refrigerator's operating modes is achieved. The controller can respond to different operating commands, including a silent energy-saving mode (second mode). In this mode, the refrigerator adjusts the duty cycle of the refrigeration fan unit and the refrigerator fan unit, as well as the operating speed of the compressor, based on real-time monitored temperature data.

[0059] Specifically, when the temperatures of the first and second compartments are within the set freezing and refrigeration ranges, respectively, the controller will control the operation of the fan unit according to the preset first freezing duty cycle and first refrigeration duty cycle, and set the compressor operating speed to the first speed. If the temperature of either compartment exceeds the set threshold, the controller will automatically adjust the duty cycle and speed to accelerate the cooling speed and ensure that the temperature quickly returns to the set range. This adjustment is achieved by increasing the second freezing duty cycle and the second refrigeration duty cycle, and by increasing the compressor operating speed to the second speed. Preferably, the adjustment ratios of the three parameters can be consistent.

[0060] In the second mode, noise is reduced by lowering the operating frequency, while energy consumption is also reduced, providing users with a quieter and more energy-efficient operating environment.

[0061] Through the first and second modes described above, users can select different operating modes according to their individual needs. The two fans can be controlled independently, precisely adjusting the temperature for different compartments, thus avoiding the over-cooling or under-cooling problems that may occur with a single fan system. In the second mode, the two fan units can reduce their speed as needed, reducing noise generated by airflow. The two fan units can more effectively distribute cooling capacity, optimize airflow distribution inside the refrigerator, reduce temperature fluctuations, and improve cooling efficiency.

[0062] In one possible implementation, the evaporator is located in the first compartment; the refrigeration fan unit and the freezing fan unit are connected in parallel in the first compartment; the cooling capacity generated by the evaporator is transferred from the first compartment to the second compartment.

[0063] In one possible implementation, the controller is further configured to, in response to a dual-temperature control mode operation command, control the refrigeration fan unit and the refrigeration fan unit to operate in a dual-temperature control mode, such that the first compartment is a freezer compartment and the second compartment is a refrigeration compartment; the controller is further configured to, in response to a dual-freezing mode operation command, control the refrigeration fan unit and the refrigeration fan unit to operate in a dual-freezing mode, such that both the first compartment and the second compartment are freezer compartments; the controller is further configured to, in response to a dual-refrigeration mode operation command, control the refrigeration fan unit and the refrigeration fan unit to operate in a dual-refrigeration mode, such that both the first compartment and the second compartment are refrigeration compartments.

[0064] In a refrigerator provided in this application embodiment, the evaporator is disposed in the first compartment (freezer compartment), while the refrigeration fan unit and the refrigeration fan unit are disposed in parallel in the same compartment. This layout allows the cooling capacity generated by the evaporator to be effectively transferred from the first compartment to the second compartment (refrigerator compartment), achieving efficient cooling capacity distribution. Based on the refrigerator layout of this application embodiment, the refrigerator can be configured in the following mode:

[0065] Dual Temperature Control Mode: The controller can respond to dual temperature control mode operation commands, intelligently adjusting the refrigeration fan unit and the freezer fan unit to keep the first compartment in a frozen state while the second compartment remains in a refrigerated state. This mode is suitable for daily use, allowing users to flexibly adjust the temperature of different compartments as needed.

[0066] Dual Freezing Mode: In dual freezing mode, the controller adjusts the operation of the fan unit so that both the first and second compartments are used as freezing compartments. This mode is suitable for use when additional freezing space is needed, such as during holidays or when purchasing frozen food in bulk.

[0067] Dual Refrigeration Mode: In dual refrigeration mode, the controller adjusts the operation of the fan unit so that both the first and second compartments are used as refrigeration compartments. This mode is suitable for use when additional refrigeration space is needed, such as when storing large quantities of beverages or vegetables.

[0068] Figure 2 This illustration shows another refrigerator structure provided in an embodiment of this application. The refrigeration unit includes an evaporator and a compressor. The location of the evaporator determines the distribution of cooling capacity; the area closer to the evaporator is colder. By separating the refrigeration and cooling fan units, more flexible temperature control and more efficient space utilization are achieved. The number of fans in the refrigeration and cooling fan units can be one or more. By controlling the cooling source of the evaporator and the cooling capacity delivered by the compressor, the switching between upper and lower freezing and refrigeration can be achieved.

[0069] Refrigeration and cooling fan units can be connected in parallel. By operating two fans in parallel, the maximum airflow can be increased by 20%-30% without increasing the air pressure. This helps to reach the set temperature faster and improves cooling efficiency. Placing two fans side by side saves space because they can share some structural components, reducing the additional space required when placed individually.

[0070] Based on the same technical concept, embodiments of this application also provide a refrigerator control method, such as... Figure 3 As shown, the method includes:

[0071] Step 301: Control the refrigeration unit to generate cooling capacity;

[0072] Step 302: Control the refrigeration fan unit to deliver cooling capacity to the first compartment according to the duty cycle corresponding to the refrigeration fan unit;

[0073] Step 303: Control the refrigeration fan unit to deliver cooling capacity to the second compartment according to the duty cycle corresponding to the refrigeration fan unit.

[0074] In one possible implementation, the control method further includes: in response to a first mode operation command, controlling the refrigeration fan unit, the cold storage fan unit, and the compressor to operate intermittently according to a preset mode.

[0075] In one possible implementation, the control method further includes: in response to a second mode operation command, controlling the refrigeration fan unit to operate in a manner matching the second mode according to the first compartment temperature, controlling the refrigerator fan unit to operate in a manner matching the second mode according to the second compartment temperature, and controlling the compressor to operate in a manner matching the second mode.

[0076] Specifically, based on the first compartment temperature being within a set freezing range and the second compartment temperature being within a set refrigeration range, the operation of the refrigeration fan unit is controlled according to the first freezing duty cycle, and the operation of the refrigeration fan unit is controlled according to the first refrigeration duty cycle, thereby controlling the operating speed of the compressor to the first speed.

[0077] Specifically, based on the first compartment temperature being higher than a set first freezing threshold and / or the second compartment temperature being higher than a set first refrigeration threshold, the operation of the refrigeration fan unit is controlled according to a second freezing duty cycle, which is obtained by adjusting the first freezing duty cycle; the operating frequency corresponding to the second freezing duty cycle is higher than the operating frequency of the first freezing duty cycle; the operation of the refrigeration fan unit is controlled according to a second refrigeration duty cycle, which is obtained by adjusting the first refrigeration duty cycle; the operating frequency corresponding to the second refrigeration duty cycle is higher than the operating frequency of the first refrigeration duty cycle; the operating speed of the compressor is controlled to a second speed, which is obtained by adjusting the first speed; the second speed is higher than the first speed.

[0078] Figure 4 The present application provides a logic control flowchart, which includes:

[0079] Step 1: The user turns on the refrigerator and selects either normal mode (the first mode mentioned above) or silent mode (the second mode mentioned above);

[0080] Step 2: In normal mode, the compressor and duct fan start and automatically switch speeds to the appropriate level according to the ambient temperature.

[0081] Step 3: In silent mode, the compressor and duct fan will operate at the lowest speed set and maintain the lowest speed for a set time, such as 5 minutes, to meet the room temperature rise requirements.

[0082] Step 4: After the set time, the temperature sensor starts monitoring the temperature of the refrigerator and freezer compartments and checks whether the temperature has reached the preset threshold.

[0083] Step 5: If the temperature does not reach the threshold, increase the speed of the compressor and the duct fan proportionally, and continue to run at the increased speed for the set time. The set time can be 5 minutes, and the ratio can be 10%.

[0084] Step 6: After the set time, monitor the temperature again. If the temperature reaches the threshold: maintain the compressor and duct fan at their lowest speeds. If the temperature still does not reach the threshold: increase the compressor and duct fan speeds proportionally again, and continue running at the increased speeds for the set time. Repeat the steps until the temperature reaches the preset threshold. Once the temperature meets the requirements, the refrigerator will maintain operation at the lowest speed.

[0085] In silent mode, both the compressor and the fan operate at their lowest speeds to reduce noise. Once the temperature sensor detects that the compartment temperature exceeds a preset threshold, the system automatically increases the speeds of both the compressor and the fan by the same percentage. This adjustment continues for a certain period to ensure effective temperature control. After the set time, the system checks the compartment temperature again. If the temperature is still above the threshold, the system continues to adjust the speed; if the temperature has fallen back to a safe range, the speed is reduced to maintain energy efficiency and quiet operation. This process cycles continuously, ensuring the refrigerator effectively prevents food spoilage while maintaining low noise levels.

[0086] This intelligent temperature control strategy not only enhances the user experience but also improves the refrigerator's energy efficiency and food preservation.

[0087] Table 1

[0088]

[0089] Table 1 shows the duty cycle adjustments of the compressor and duct fan at different speeds under different modes. It is divided into two main sections: "Normal Mode" and "Silent Mode," each further divided into "Refrigeration Request" and "Freezing Request." The values ​​in the table represent the compressor and duct fan speeds under different requests.

[0090] In normal mode, if a refrigeration request is received, the compressor speed starts at 1500 RPM and gradually increases to 2500 RPM as the request increases. The duct fan speed starts at 640 RPM and gradually increases to 1700 RPM. If a freezing request is received, the compressor speed starts at 1600 RPM and gradually increases to 2600 RPM. The duct fan speed starts at 740 RPM and gradually increases to 1900 RPM.

[0091] In silent mode, if a refrigeration request is received, the compressor and duct fan speeds are increased by 10%, 20%, and 30% respectively, based on 1500 RPM and 640 RPM. For example, if 10% is increased from 1500 RPM, the speed becomes 1650 RPM. If a freezing request is received, the compressor and duct fan speeds are increased by 10%, 20%, and 30% respectively, based on 1600 RPM and 740 RPM.

[0092] Tables 2a and 2b list the noise and vibration data of the fan at different speeds (640 rpm, 800 rpm, 1000 rpm, 1300 rpm, and 1700 rpm). The noise data are divided into four different sound pressure level standards (A, B, SL, SR), each with a corresponding noise value (unit: decibels, dB). These data demonstrate the noise levels at different speeds and with SPL increases (5%, 10%, and 20%).

[0093] Table 2a

[0094]

[0095] Table 2b

[0096]

[0097] Tables 3a and 3b list the noise and vibration data of the compressor at different speeds (1500 rpm, 1650 rpm, 2400 rpm, 1800 rpm, and 21000 rpm).

[0098] Noise data is also presented in four different sound pressure level (SPL) standards (A, B, 8L, BR), each with corresponding noise values. These data demonstrate noise levels at different speeds and SPL increases (5%, 10%, 20%). Vibration data provides vibration values ​​at different locations, including COMP Top, COMP Front, COMP Static, Upper Connector, Middle Connector, Lower Connector, Upper Drawer, and Lower Connector. Vibration values ​​are expressed as acceleration (in meters per second², m / s²). 2 The values ​​are expressed as displacement (in millimeters per second, mm / s). The last row of the table provides the operating power (in watts, W) at different speeds. The "Result Judgment" at the bottom of the table shows whether the equipment passes the test under different speeds and SPL increases.

[0101] Table 3b

[0102]

[0103]

[0104] Through the fan duty cycle tests conducted in this application embodiment, the noise and airflow performance of the fan at different duty cycles were observed. It was found that when the fan duty cycle was increased by 10%, the noise increase was not significant, but the airflow increased. Further testing at 20% duty cycles per level revealed an excessive noise increase, affecting the effectiveness of the silent mode. The vibration and noise performance of the compressor at different duty cycle increases were also tested. At a 5% duty cycle increase, vibration was significant at lower speeds. At a 10% duty cycle increase, vibration decreased. When the compressor duty cycle was increased to 20%, intake and exhaust noise became the main factor. The noise level increased significantly, affecting the effectiveness of the silent mode. The test results for both the fan and compressor were considered comprehensively.

[0105] Therefore, a 10% duty cycle is used as the standard amplitude for increasing the fan and compressor speeds in silent mode, because it increases airflow and reduces vibration while avoiding a significant increase in noise, ensuring that the refrigerator can provide sufficient cooling while maintaining a low noise level in silent mode.

[0106] In summary, this application provides a refrigerator system and a control method for the refrigerator system. The refrigerator includes: a refrigeration fan unit for supplying cold air to a first compartment, comprising one or more refrigeration fans; a refrigeration fan unit for supplying cold air to a second compartment, comprising one or more refrigeration fans; a refrigeration unit for providing and supplying cold air; and a controller connected to the refrigeration fan unit, the refrigeration fan unit, and the refrigeration unit, respectively, controlling the duty cycle of the refrigeration fan unit and the refrigeration fan unit and the operating speed of the compressor in several operating modes. By using dual fans instead of the traditional single fan, the overall operating speed of the fans is reduced, thus reducing refrigerator noise. Through the independent setting of the refrigeration fan unit and the refrigeration fan unit, the operating mode and temperature of the compartments are independently controlled, improving the accuracy of temperature regulation, increasing the flexibility of operating modes, and enabling the system to achieve a higher energy efficiency ratio and reduce energy consumption.
