Description

Technical Field

[0001] This disclosure relates to the field of refrigerators, and in particular to a refrigerator control method and device, a refrigerator, and a computer storage medium. Background Technology

[0002] Frost-free refrigerators defrost the evaporator at regular intervals during operation. During defrosting, the defrosting heating element inside the refrigerator generates heat to melt the frost. Therefore, the temperature inside the refrigerator increases significantly during the defrosting process.

[0003] In related technologies, during the temperature-raising phase after defrosting, the compressor is typically started to quickly lower the temperature inside the refrigerator compartment, generating cooling capacity through its operation. However, if the compressor runs at high speed continuously, it will produce significant noise, causing inconvenience to the user. If the compressor runs at low speed, although the noise level is lower, the cooling effect is slower, and the temperature inside the refrigerator compartment cannot drop in time, thus affecting the refrigerator's preservation effect.

[0004] The information disclosed in the background section is only intended to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] One objective of this disclosure is to reduce the noise generated by the compressor during the temperature-raising phase after the defrosting process in a refrigerator, and to minimize the impact on the refrigerator's cooling demand.

[0006] To solve the above-mentioned technical problems, the present disclosure adopts the following technical solution:

[0007] According to one aspect of this disclosure, a refrigerator control method is provided, the refrigerator having a compressor, the method comprising:

[0008] After the defrosting process is complete, start the compressor;

[0009] Monitor the degree of temperature drop in each compartment of the refrigerator;

[0010] The amount of reduction in compressor speed is adjusted according to the degree of decrease in the compartment temperature.

[0011] According to one aspect of this disclosure, a refrigerator control device is provided, comprising:

[0012] The compressor control module is used to start the compressor after defrosting to lower the temperature inside the refrigerator compartment.

[0013] A temperature monitoring module is used to monitor the compartment temperature inside the refrigerator compartment;

[0014] The compressor speed adjustment module is used to adjust the amount of reduction in compressor speed according to the degree of decrease in the temperature of the compartment.

[0015] According to another aspect of this disclosure, a refrigerator is provided, comprising:

[0016] The storage unit stores the refrigerator control program;

[0017] The processing unit is used to execute the steps of the refrigerator control method when the refrigerator control program is running.

[0018] The technical solution disclosed herein adjusts the compressor speed adaptively during the temperature-reducing phase after defrosting, based on the degree of temperature decrease in the refrigerator compartment. This optimizes the compressor speed while meeting cooling requirements, thereby reducing compressor noise and improving the user experience. Furthermore, compared to related technologies, the reduced compressor speed in this solution lowers compressor energy consumption, contributing to energy conservation.

[0033] The preferred embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings.

[0034] This disclosure proposes a refrigerator control method. The structure of the refrigerator will be described first. Please refer to [link / reference needed]. Figure 1 , Figure 1 This is a schematic diagram of the structure of a refrigerator according to an example. The refrigerator of this embodiment has an approximately cuboid shape. The appearance of the refrigerator is defined by a storage compartment that defines the storage space and a plurality of doors disposed in the storage compartment. The door 200 includes a door shell 210 located outside the storage compartment 100, a door inner liner 220 located inside the storage compartment 100, an upper end cover 230, a lower end cover 240, and an insulation layer located between the door shell 210, the door inner liner 220, the upper end cover 230, and the lower end cover 240; typically, the insulation layer is filled with foam material.

[0035] Storage compartment 100 has an open body and is vertically divided into a lower freezer compartment 110 and an upper refrigerator compartment 120. Each of the separated spaces can have independent storage space. Specifically, the freezer compartment 110 is located on the lower side of storage compartment 100 and can be selectively covered by a drawer-type freezer door. The space above the freezer compartment 110 is divided into left and right sides to form refrigerator compartments 120 respectively, which can be selectively opened or closed by refrigerator doors pivotally mounted on them.

[0036] A refrigerator's refrigeration system includes a condenser, evaporator, and compressor. Refrigerators achieve cooling by utilizing evaporation for cooling or vaporization for heat absorption. The refrigerator's refrigeration piping contains refrigerant. In its gaseous state, the refrigerant is pressurized by the compressor and then enters the condenser through the discharge pipe, where it dissipates heat and condenses into a liquid refrigerant.

[0037] After the liquid refrigerant enters the evaporator, it evaporates and absorbs heat to become a gaseous refrigerant. The air and food inside the container absorb this heat, thus achieving cooling. The vaporized refrigerant is then compressed again by the compressor, continuously circulating to maintain cooling inside the container.

[0038] The evaporator is installed in the refrigerator's air circulation system. When the evaporator is continuously exchanging heat and is at a low temperature, frost will form on it. When the frost accumulates, it will affect the heat exchange efficiency of the evaporator. Therefore, refrigerators usually have a defrost heater inside to generate heat to melt the frost on the evaporator fins, thus achieving the purpose of defrosting.

[0039] In some embodiments, a temperature sensor is provided on the refrigerator evaporator to detect the temperature on the evaporator. Here, the refrigerator may defrost at predetermined intervals, or the refrigerator may activate the defrosting heater to defrost the evaporator when the temperature on the evaporator drops to a certain value based on the temperature value detected by the temperature sensor.

[0040] The following embodiments will describe examples of the refrigerator control method of this disclosure. The refrigerator control method of this disclosure can reduce the noise generated by the compressor after defrosting and minimize the impact on the refrigerator's preservation effect by controlling the compressor speed during the temperature-raising phase after defrosting.

[0041] Please see Figure 2 , Figure 2 This is a flowchart illustrating a refrigerator control method according to an example. In some embodiments, the refrigerator control method includes:

[0042] Step S40: After the defrosting process is completed, start the compressor.

[0043] Here, the refrigerator compartment can be understood as the freezer compartment. During the defrosting process, the defrost heater operates to generate heat, thus raising the temperature inside the refrigerator compartment. Therefore, in order not to affect the preservation of food inside the refrigerator, the compressor needs to be started immediately after the defrosting process ends to cool the compartment.

[0044] It should be understood that the refrigerator contains a control unit that controls the operation of the compressor and defrost heater. Therefore, the control unit can determine that defrosting is complete after the defrost heater stops heating, and then control the compressor to start. Alternatively, the control unit can obtain the temperature detected by the temperature sensor on the evaporator, and thus determine whether defrosting is complete based on the evaporator temperature. For example, when the evaporator temperature reaches 0°C, the controller determines that defrosting is complete, and at this time, the compressor is started.

[0045] Step S41: Monitor the compartment temperature of the refrigerator.

[0046] In some embodiments, at least one temperature sensor is installed in the refrigerator compartment to detect the temperature inside the compartment. When multiple temperature sensors are installed, the compartment temperature can be the average of the temperature values ​​detected by the multiple temperature sensors.

[0047] In some embodiments, the refrigerator control unit can read the temperature value detected by the temperature sensor at predetermined intervals. The predetermined interval can be 0.5 seconds to 10 seconds. It can be specifically set according to the refrigerator capacity and evaporator size.

[0048] Step S42: Adjust the amount of reduction in compressor speed according to the degree of decrease in the compartment temperature.

[0049] In this embodiment, after defrosting, the compressor does not operate at a fixed speed, but rather adjusts its speed according to the compartment temperature. Generally, the greater the decrease in compartment temperature, the greater the reduction in compressor speed. For example, the compressor speed corresponding to a compartment temperature of 5°C is greater than the compressor speed corresponding to a compartment temperature of 2°C.

[0050] However, this does not mean that every change in compartment temperature must correspond to a change in compressor speed. It is possible to divide the temperature change process into several consecutive temperature ranges, within which the compressor speed varies accordingly.

[0051] The operating load of a refrigerator varies depending on the ambient temperature. In the high temperatures of summer, the refrigerator dissipates heat slowly, resulting in a higher load on the refrigeration system. The inverter compressor needs to operate at a higher speed to overcome the load resistance and lower the compartment temperature. In the low temperatures of winter, the refrigerator dissipates heat quickly, resulting in a lower load on the refrigeration system. The inverter compressor can then meet the compartment temperature requirements at a lower operating speed.

[0052] Therefore, in order to achieve more precise control of the compressor speed, so as to meet the requirements of food preservation while minimizing unnecessary energy waste, please refer to... Figure 3 , Figure 3 This is based on an example. Figure 2 The flowchart of step S42. In one embodiment, step S42, adjusting the amount of reduction in the compressor speed according to the degree of decrease in the compartment temperature, includes:

[0053] Step S421: Obtain the ambient temperature of the environment where the refrigerator is located;

[0054] The ambient temperature of the refrigerator can be measured by a temperature sensor installed on the outside of the refrigerator, or by the refrigerator control unit acquiring the ambient temperature detected by other temperature detection devices through the Internet of Things.

[0055] Step S422: Based on the preset correspondence between ambient temperature and compressor normal operating speed, determine the normal operating speed of the compressor corresponding to the ambient temperature.

[0056] Here, the compressor's normal operating speed can be understood as the compressor's operating speed under normal refrigerator operating conditions (the defrosting process is not considered normal refrigerator operating conditions). Under normal refrigerator operating conditions, the compressor's normal operating speed corresponds to the ambient temperature. This correspondence can be expressed in the form of tables, curves, functions, etc.

[0057] As can be seen, after obtaining the ambient temperature of the refrigerator's environment, the normal operating speed of the compressor under normal refrigerator conditions can be found based on the preset correspondence between the ambient temperature and the normal operating speed of the compressor.

[0058] Step S423: Based on the degree of decrease in the compartment temperature and the normal operating speed of the compressor, reduce the compressor speed.

[0059] In this step, after determining the degree of temperature reduction in the compartment, the compressor speed is controlled based on the compressor's normal operating speed. This allows the adjusted compressor speed to better take into account the influence of ambient temperature, thus achieving a balance between satisfying food preservation and compressor energy consumption.

[0060] Furthermore, in some embodiments, the preset relationship between ambient temperature and the compressor's normal operating speed includes the preset relationship between ambient temperature and the compressor's normal operating speed setting.

[0061] Step S422, determining the normal operating speed of the compressor corresponding to the ambient temperature based on the preset correspondence between ambient temperature and the normal operating speed of the compressor, includes:

[0062] Based on the preset correspondence between ambient temperature and the compressor's normal operating speed setting, the normal operating speed setting of the compressor corresponding to the ambient temperature is determined.

[0063] Step S423, which involves reducing the compressor speed based on the degree of decrease in the compartment temperature and the compressor's normal operating speed, includes:

[0064] The compressor speed setting is adjusted based on the degree of temperature reduction in the compartment and the compressor's normal operating speed setting.

[0065] In one example, the relationship between the compressor's normal operating speed and ambient temperature is shown in a table. Table 1 is a table showing the correspondence between the compressor's normal operating speed and ambient temperature, based on an example.

[0066] Table 1

[0067] Ambient temperature compressor normal operating speed T < T1 1st gear T1 < T < T2 2nd gear T2 < T < T3 3rd gear T3>T 4 gears

[0068] As shown in the table, the compressor has four speed settings, numbered 1, 2, 3, and 4 from lowest to highest speed. It also has three temperature nodes: T1, T2, and T3. T2 is greater than T1. When the ambient temperature is lower than T1, indicating a low ambient temperature, the compressor operates at speed 1 to meet the cooling requirements. When the ambient temperature is higher than T1 but lower than T2, the compressor operates at speed 2; when the ambient temperature is higher than T2 but lower than T3, the compressor operates at speed 3; and when the ambient temperature is higher than T3, the compressor operates at speed 4.

[0069] It should be understood that, depending on the type of compressor, the compressor may not have speed settings, meaning the compressor can achieve stepless speed regulation. Furthermore, the number of temperature nodes is not limited to three; it can be less than three or more.

[0070] As can be seen, after obtaining the ambient temperature of the refrigerator's environment, the normal operating speed of the compressor under normal refrigerator conditions can be found by referring to the preset table of correspondence between ambient temperature and the normal operating speed of the compressor.

[0071] Furthermore, in some embodiments, the compressor has a start-up temperature, and the compressor starts when the compartment temperature is greater than or equal to the start-up temperature;

[0072] The step of adjusting the compressor speed setting based on the degree of temperature reduction in the compartment and the compressor's normal operating speed setting includes:

[0073] Step S4231: Determine the difference between the compartment temperature and the compressor start-up temperature.

[0074] Here, the start-up temperature refers to the temperature at which the compressor starts to cool the compartment when the compartment temperature reaches the start-up temperature under normal refrigerator operating conditions (defrosting is not part of normal refrigerator operating conditions). When the refrigerator is operating in defrost mode, the compressor will not start even if the start-up temperature is reached because a higher compartment temperature is required.

[0075] It should be noted that the start-up temperature can be set by the manufacturer before the refrigerator leaves the factory. Alternatively, the start-up temperature can be adjustable, allowing the user to adjust it according to the refrigerator's operating environment and intended use. The control unit can calculate the difference between the compartment temperature and the compressor start-up temperature. As mentioned earlier, compartment temperature detection is continuous; therefore, each time the compartment temperature is detected, the compressor speed is readjusted based on the difference between the measured temperature and the compressor start-up temperature.

[0076] Step S4232: When the difference between the chamber temperature and the compressor start-up temperature is greater than the first temperature difference Δt1 and less than the second temperature difference Δt2, the compressor's operating speed is controlled to be lowered to one or two levels higher than the normal operating speed; wherein, the first temperature difference Δt1 is less than the second temperature difference Δt2.

[0077] Here, the first temperature difference Δt1 and the second temperature difference Δt2 can be fixed and unadjustable values, or they can be changed by the user. In one example, the first temperature difference Δt1 is 0℃.

[0078] After defrosting, if the temperature difference Δt between the room temperature and the compressor start-up temperature reaches a temperature range greater than the first temperature difference Δt1 and less than the second temperature difference Δt2, the control unit will first determine the corresponding normal operating speed setting based on the current ambient temperature. For example, if it is at speed 2, the control unit will then control the compressor to run at speed 3.

[0079] Furthermore, in some embodiments, after step S4231, the step of determining the difference between the compartment temperature and the compressor start-up temperature, the method further includes:

[0080] Step S4233: When the difference between the chamber temperature and the compressor start-up temperature is greater than or equal to the second temperature difference Δt2, control the compressor speed to be adjusted to three speeds higher than the normal operating speed, or to operate at the highest speed.

[0081] In this embodiment, if the temperature difference Δt between the room temperature and the compressor start temperature reaches a value greater than or equal to the second temperature difference Δt2 after defrosting, the control unit directly controls the compressor to run at level 4 (assuming level 4 is the highest level of compressor operation).

[0082] This embodiment enables the refrigerator to maintain its cooling requirements by rapidly reducing the compartment temperature during the warm-up phase after defrosting, when the compartment temperature is high.

[0083] In some embodiments, after step S4231, which involves determining the difference between the compartment temperature and the compressor start-up temperature, the method further includes:

[0084] Step S4234: When the difference between the chamber temperature and the compressor start-up temperature is less than the first temperature difference Δt1, control the compressor to run at the normal operating speed setting.

[0085] In this embodiment, if the temperature difference Δt between the compartment and the compressor start-up temperature is less than the first temperature difference Δt1 after defrosting, the control unit will first determine the corresponding normal operating speed setting based on the current ambient temperature. For example, if it is at speed 2, the control unit will then control the compressor to continue operating at speed 2.

[0086] This embodiment enables the compressor to reduce energy consumption during the warm-up phase after defrosting if the compartment temperature is not too high, by not increasing the compressor speed.

[0087] As mentioned earlier, during the warm-up phase after defrosting, the compressor speed is not constant, but is adjusted according to the degree of temperature drop in the compartment.

[0088] Table 2 shows the correspondence between compressor speed settings, compressor normal operating settings, and ambient temperature, based on an example.

[0089] Table 2

[0090]

[0091] Assuming the ambient temperature is lower than the first temperature node T1, the corresponding normal operating speed setting is level 1. Also, assuming that during the warm-up phase after defrosting, the temperature difference between the compartment and the compressor start-up temperature is greater than the second temperature difference Δt2, the control unit controls the compressor to operate at the highest setting, level 4. As the compressor operates, the temperature inside the compartment continuously decreases. When the temperature difference Δt between the compartment and the compressor start-up temperature is greater than the first temperature difference Δt1 and less than the second temperature difference Δt2, the control unit controls the compressor to operate at a speed one level higher than the normal operating speed setting, i.e., level 2. As the compressor continues to operate, the temperature inside the compartment is further reduced. When the temperature difference Δt between the compartment and the compressor start-up temperature is less than the first temperature difference Δt1, the control unit controls the compressor to operate at the normal operating speed setting, i.e., level 1. This continues until the compartment temperature reaches the compressor's shutdown temperature, at which point the control unit shuts down the compressor.

[0092] This embodiment combines ambient temperature, the compressor's normal operating speed setting, and compartment temperature to control the compressor speed. This allows the refrigerator to automatically adjust the compressor speed according to cooling needs, achieving a reasonable reduction in compressor speed while meeting cooling requirements. This reduces compressor noise and improves the user experience. Furthermore, compared to related technologies, the reduced compressor speed in this disclosure reduces compressor energy consumption, thus contributing to energy conservation.

[0093] Furthermore, it should be noted that the above figures are merely illustrative representations of the processes included in the methods according to exemplary embodiments of this disclosure, and are not intended to be limiting. It is readily understood that the processes shown in the above figures do not indicate or limit the temporal order of these processes. Additionally, it is readily understood that these processes may be executed synchronously or asynchronously, for example, in multiple modules.

[0094] As mentioned earlier, the compressor needs to be started during the warm-up phase after defrosting. Here, the compressor can be directly controlled to run at its highest speed. In some embodiments, starting the compressor after defrosting includes:

[0095] After the defrosting process is completed, the compartment temperature inside the refrigerator is obtained;

[0096] Control the compressor to start, and set the compressor's operating speed according to the chamber temperature.

[0097] In one example, the control of starting the compressor and setting the compressor's operating speed according to the compartment temperature includes:

[0098] Obtain the ambient temperature of the environment where the refrigerator is located;

[0099] Based on the preset correspondence between ambient temperature and the compressor's normal operating speed setting, the normal operating speed setting of the compressor corresponding to the ambient temperature is determined.

[0100] Determine the difference between the compartment temperature and the compressor start-up temperature;

[0101] When the difference between the compartment temperature and the compressor start-up temperature is greater than the first temperature difference and less than the second temperature difference, the compressor's operating speed is controlled to be one or two levels higher than the normal operating speed.

[0102] When the difference between the chamber temperature and the compressor start-up temperature is greater than or equal to the second temperature difference, the compressor speed is controlled to be three speeds higher than the normal operating speed, or it is operated at the highest speed.

[0103] When the difference between the chamber temperature and the compressor start-up temperature is less than the first temperature difference, the compressor is controlled to operate at the normal operating speed setting.

[0104] The relationship between the preset ambient temperature and the compressor's normal operating speed setting is the same as above.
