Description

Technical Field

[0001] This disclosure relates to the field of refrigerator control technology, specifically to a refrigerator control method, device, refrigerator, and storage medium. Background Technology

[0002] The basic refrigeration process of a refrigerator includes: the compressor compresses the refrigerant from a low-temperature, low-pressure gas into a high-temperature, high-pressure gas, then condenses it into a medium-temperature, high-pressure liquid in the condenser, and then passes it through a filter and capillary tube to become a low-temperature, low-pressure liquid. The low-temperature, low-pressure liquid refrigerant enters the evaporator, where it absorbs heat and evaporates to become a low-temperature, low-pressure vapor. It is then sent back into the compressor to be compressed into a high-temperature, high-pressure gas, thus completing the refrigeration cycle.

[0003] It is evident that when the low-temperature, low-pressure steam output from the evaporator enters the compressor through the suction pipe, the low-temperature, low-pressure gas easily causes condensation in the suction pipe. This condensation can damage compressor components, such as causing metal parts to rust, which in turn leads to a decrease in the refrigerator's cooling performance. Summary of the Invention

[0004] This disclosure provides a refrigerator control method, apparatus, refrigerator, and storage medium, aiming to solve the condensation problem in the compressor suction pipe and thereby improve the refrigerator's cooling performance.

[0005] In a first aspect, embodiments of this disclosure provide a refrigerator control method, including:

[0006] Obtain the ambient temperature and humidity of the environment where the refrigerator is located;

[0007] If the ambient temperature is greater than a preset ambient temperature threshold and the ambient humidity is greater than a preset ambient humidity threshold, then the target temperature of the suction pipe of the compressor inside the refrigerator is obtained.

[0008] If the target temperature is lower than the preset dew point temperature, adjust the compressor speed and condenser fan speed in the refrigerator until the target temperature is higher than the preset dew point temperature.

[0009] Secondly, embodiments of this disclosure provide a refrigerator control device, the refrigerator control device comprising:

[0010] The first acquisition module is used to acquire the ambient temperature and humidity of the environment where the refrigerator is located;

[0011] The second acquisition module is used to acquire the target temperature of the suction pipe of the compressor inside the refrigerator if the ambient temperature is greater than a preset ambient temperature threshold and the ambient humidity is greater than a preset ambient humidity threshold.

[0012] The adjustment module is used to adjust the compressor speed and condenser fan speed in the refrigerator if the target temperature is lower than the preset dew point temperature, until the target temperature is higher than the preset dew point temperature.

[0013] Thirdly, embodiments of this disclosure also provide a refrigerator, including a memory storing multiple instructions; a processor loads instructions from the memory to execute the steps of any of the refrigerator control methods provided in embodiments of this disclosure.

[0014] Fourthly, embodiments of this disclosure also provide a computer-readable storage medium storing a plurality of instructions adapted for loading by a processor to perform the steps of any of the refrigerator control methods provided in embodiments of this disclosure.

[0015] Compared to existing refrigerator anti-condensation strategies, this disclosure can obtain the temperature of the suction pipe connected to the compressor when both the ambient temperature and humidity of the refrigerator's environment exceed corresponding thresholds. If this temperature exceeds a preset dew point temperature, the compressor speed and condenser fan speed are adjusted to raise the suction pipe temperature above the preset dew point temperature, effectively alleviating condensation on the suction pipe surface. Based on this, this disclosure can effectively eliminate the damage to the compressor caused by suction pipe condensation and improve the refrigerator's cooling performance.

[0023] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. Furthermore, in the description of the embodiments of this disclosure, the terms "first," "second," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. Therefore, features defined with "first" or "second" may explicitly or implicitly include one or more features. In the description of the embodiments of this disclosure, "multiple" means two or more, unless otherwise explicitly specified.

[0024] This disclosure provides a refrigerator control method, apparatus, refrigerator, and computer-readable storage medium.

[0025] Specifically, this embodiment will be described from the perspective of a refrigerator control device, which can be integrated into the refrigerator. That is, the refrigerator control method of this embodiment can be executed by the refrigerator, or optionally, by other devices with integrated compressors.

[0026] The following detailed description is provided in conjunction with the accompanying drawings. In this embodiment, a refrigerator is used as an example of the executing entity. It should be noted that the order of description in the following embodiments is not intended to limit the preferred order of the embodiments. Although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in a different order than that shown in the accompanying drawings.

[0027] According to the above background technology description, when the low-temperature and low-pressure steam output from the evaporator enters the compressor through the suction pipe, the low-temperature and low-pressure gas is prone to condensation in the suction pipe.

[0028] In addition, condensation occurs on the refrigerator's suction pipe or door seal under operating conditions of 25℃ and 90% relative humidity and 32℃ and 85% relative humidity. The existing common solutions to this problem are to lengthen the return air heat exchange section, add insulation cotton to the suction pipe, modify the air duct, and modify the door seal.

[0029] To address the aforementioned condensation problem in refrigerators, this disclosure proposes a refrigerator control method, apparatus, refrigerator, and computer-readable storage medium, aiming to effectively solve the condensation problem in refrigerators.

[0030] Please refer to Figure 1 The specific process of this refrigerator control method can be summarized in steps S10 to S30:

[0031] Step S10: Obtain the ambient temperature and humidity of the environment where the refrigerator is located;

[0032] It should be noted that in this embodiment, the risk of condensation in the refrigerator is low under low ambient temperature and humidity. In order to reduce refrigerator energy consumption, the refrigerator does not need to turn on the anti-condensation function and can operate normally.

[0033] Therefore, the refrigerator can obtain the ambient temperature and humidity of its surroundings through its built-in temperature and humidity sensors.

[0034] Step S20: If the ambient temperature is greater than a preset ambient temperature threshold and the ambient humidity is greater than a preset ambient humidity threshold, then obtain the target temperature of the suction pipe of the compressor inside the refrigerator.

[0035] After obtaining the ambient temperature and humidity of its surroundings, the refrigerator can determine whether the ambient temperature exceeds a preset ambient temperature threshold and whether the ambient humidity exceeds a preset ambient humidity threshold. Furthermore, if both the ambient temperature and humidity exceed the preset ambient temperature and humidity thresholds, the refrigerator can obtain the target temperature of the compressor's suction pipe.

[0036] Specifically, for example, the preset ambient temperature threshold Hd can be set to 20℃ (at lower ambient temperatures, the absolute humidity of the air is lower, and there is basically no risk of condensation), and the ambient humidity threshold Hs can be set to 75% (the humidity collected by the temperature and humidity sensors is relative humidity; at lower relative humidity, the refrigerator also has basically no risk of condensation). Based on this, the refrigerator can collect the target temperature of the air intake pipe through the temperature sensor on the surface of the air intake pipe.

[0037] It is understood that in this embodiment, the compressor's suction pipe is connected to the evaporator, drawing in the low-temperature, low-pressure gas discharged from the evaporator to the compressor, while the compressor, suction pipe, and condenser are all located inside the compressor compartment.

[0038] Step S30: If the target temperature is lower than the preset dew point temperature, adjust the compressor speed and condenser fan speed in the refrigerator until the target temperature is higher than the preset dew point temperature.

[0039] It should be noted that, in this embodiment, the dew point temperature can be understood as the temperature at which water vapor in the air begins to condense into liquid under a certain pressure. When the actual temperature is lower than the dew point temperature, water vapor will begin to condense into droplets.

[0040] Therefore, when the refrigerator detects that the target temperature of the suction pipe is lower than the preset dew point temperature, it can adjust the compressor speed and the condenser fan speed until the target temperature is higher than the preset dew point temperature.

[0041] Specifically, for example, a refrigerator can increase the compressor speed, causing it to run at high speed and generate more heat. This results in a higher temperature inside the compressor compartment, which in turn raises the temperature of the suction pipe, reducing condensation there. Consequently, the exhaust temperature of the refrigeration cycle also increases, improving the condensation prevention on the door seal. Simultaneously, the refrigerator can reduce the condenser fan speed, temporarily decreasing the refrigerator's cooling performance.

[0042] As can be seen, in this embodiment, the refrigerator can obtain the ambient temperature and humidity of its surroundings through its built-in temperature and humidity sensors. After obtaining the ambient temperature and humidity, the refrigerator can determine whether the ambient temperature is greater than a preset ambient temperature threshold and whether the ambient humidity is greater than a preset ambient humidity threshold. Furthermore, if it is determined that both the ambient temperature and humidity are greater than the preset ambient temperature and humidity thresholds, the refrigerator can obtain the target temperature of the compressor's suction pipe. When the refrigerator detects that the target temperature of the suction pipe is lower than the preset dew point temperature, it can adjust the compressor speed and the condenser fan speed until the target temperature is higher than the preset dew point temperature.

[0043] Compared to existing refrigerator anti-condensation strategies, this disclosure can obtain the temperature of the suction pipe connected to the compressor when both the ambient temperature and humidity of the refrigerator's environment exceed corresponding thresholds. If this temperature exceeds a preset dew point temperature, the compressor speed and condenser fan speed are adjusted to raise the suction pipe temperature above the preset dew point temperature, effectively alleviating condensation on the suction pipe surface. Based on this, this disclosure can effectively eliminate the damage to the compressor caused by suction pipe condensation and improve the refrigerator's cooling performance.

[0044] In one embodiment, step S30 above, "if the target temperature is lower than the preset dew point temperature, then adjust the compressor speed and condenser fan speed in the refrigerator," may include:

[0045] Step S301: If the target temperature is lower than the preset dew point temperature, increase the compressor speed in the refrigerator to the preset speed threshold and obtain the compressor's running time.

[0046] Step S302: If the running time does not exceed a preset time threshold, then the condenser fan in the refrigerator is turned off;

[0047] Step S303: If the running time exceeds a preset time threshold, control the condenser fan to run at the lowest speed.

[0048] It should be noted that in this embodiment, when the refrigerator obtains that the target temperature of the suction pipe surface is lower than the preset dew point temperature, the compressor speed can be increased to the preset speed threshold.

[0049] As explained above, the compressor's suction pipe connects to the evaporator, drawing in the low-temperature, low-pressure gas discharged from the evaporator. The compressor, suction pipe, and condenser are all located within the compressor compartment. Therefore, the refrigerator can increase the compressor speed to a preset speed threshold, such as 3800 rpm or higher. At high speeds, the compressor generates significantly more heat, rapidly raising the temperature within the compressor compartment. This also rapidly increases the temperature of the suction pipe within the compressor compartment, effectively reducing condensation on the suction pipe. Consequently, the exhaust temperature of the refrigerator's refrigeration cycle also increases, allowing the anti-condensation pipe to effectively solve the condensation problem on the refrigerator door seal.

[0050] Furthermore, the refrigerator can track the compressor's runtime.

[0051] If the compressor runs for longer than the preset time threshold, the refrigerator's condenser fan can be turned on and controlled to run at the lowest speed.

[0052] For example, in this embodiment, the preset duration threshold can be 2 minutes, that is, the condenser fan can be turned on after the compressor has been running for two minutes.

[0053] It should be noted that in this embodiment, when the compressor is running, the return gas heat exchange between the capillary tube and the suction pipe has not been effectively established. At this time, the temperature of the suction pipe is the lowest, and condensation is easily generated on the surface of the suction pipe. The condensation effect is not conducive to the rapid establishment of return gas heat exchange. Therefore, the refrigerator can delay the start of the condenser fan. For example, the condenser fan can be started when the compressor has been running for a longer than a preset time threshold, and the condenser fan can be controlled to run at the lowest speed.

[0054] Specifically, for example, a refrigerator can control the condenser fan to operate at the lowest controllable speed. For instance, for a condenser fan that is adjustable from 7 to 12V, the speed corresponding to a voltage of L=7V can be selected.

[0055] In this embodiment, controlling the condenser fan to operate at a low speed can both promote air circulation within the compressor compartment and prevent the removal of excessive heat from the compressor compartment, which could weaken the refrigerator's cooling performance. Figure 2-1 and Figure 2-2 The test curves shown indicate that the temperature of the intake pipe can be increased by 1.3℃, and the temperature at the end of the exhaust pipe can be increased by 5℃, effectively improving the condensation problem in the intake pipe and the freezer door seal.

[0056] Furthermore, in step S30 above, after "if the target temperature is lower than the preset dew point temperature, adjust the compressor speed and condenser fan speed in the refrigerator", it may also include:

[0057] Step S40: Obtain the compartment temperature of the refrigerator;

[0058] Step S50: If the room temperature is lower than a preset temperature threshold, then turn on the heater at the suction pipe of the compressor in the refrigerator.

[0059] Step S60: Control the heater to heat the intake pipe until the target temperature is higher than the preset dew point temperature.

[0060] It should be noted that, in this embodiment, in addition to alleviating the condensation problem in the suction pipe by increasing the compressor speed and delaying the start of the condenser fan, a heater can also be installed in the suction pipe, and the heater can be in close contact with the suction pipe.

[0061] Based on this, if the refrigerator detects that the temperature inside the refrigerator is lower than the preset temperature threshold, it can turn on the heater at the suction pipe and control the heater to heat the suction pipe until the target temperature is higher than the preset dew point temperature.

[0062] It should be noted that in this embodiment, heating the suction pipe with a heater and adjusting the speed of the compressor and condenser fan can be implemented as two parallel solutions, or they can be implemented after adjusting the speed of the compressor and condenser fan. However, in order to avoid the high energy consumption caused by the compressor running at high speed for a long time, the heater can be turned on to heat the suction pipe when the room temperature is lower than the preset temperature threshold.

[0063] Therefore, in this embodiment, the compressor and condenser fan speeds can be adjusted individually, the heater can be turned on, or both can be used in combination to effectively alleviate the condensation problem on the surface of the suction pipe, and prevent the liquid condensed in the suction pipe for a long time from flowing to the compressor, causing damage to the compressor components and affecting the normal operation of the compressor.

[0064] In one embodiment, after step S30 above, "if the target temperature is lower than the preset dew point temperature, then adjust the compressor speed and condenser fan speed in the refrigerator", the following may also be included:

[0065] Step S70: Obtain the door seal temperature at the refrigerator door seal;

[0066] Step S80: If the door seal temperature is lower than the preset door seal dew point temperature, control the refrigerant in the compressor of the refrigerator to flow into the anti-condensation pipe in the refrigerator door seal;

[0067] In step S90, after the refrigerant flows into the anti-condensation pipe inside the refrigerator door seal, the condenser fan speed is reduced until the door seal temperature is higher than the preset door seal dew point temperature.

[0068] It should be noted that in this embodiment, after the refrigerator controls the operation of the compressor and the condenser fan sequentially, the door seal temperature can be collected. If the door seal temperature is lower than the preset door seal dew point temperature, then some of the refrigerant in the compressor can be controlled to flow into the anti-condensation pipe inside the refrigerator door seal.

[0069] Specifically, for example, a refrigerator can control a valve to direct some of the high-temperature, high-pressure gas (i.e., gaseous refrigerant) from the compressor into the anti-condensation pipe at the door seal.

[0070] Furthermore, after the refrigerant is introduced into the anti-condensation pipe, the speed of the condenser fan can be reduced, so that the refrigerant in the anti-condensation pipe is at a higher temperature, thereby increasing the temperature of the anti-condensation pipe and raising it to exceed the preset door seal dew point temperature, thus alleviating the condensation phenomenon at the door seal.

[0071] After step S90 above, "after the refrigerant flows into the anti-condensation pipe inside the refrigerator door seal, reduce the condenser fan speed", the following may also be included:

[0072] Step S100: If the door seal temperature is lower than the preset door seal dew point temperature after a preset time, control the refrigerator's refrigeration fan to run and obtain the compartment temperature of the freezer compartment in the refrigerator.

[0073] Step S110: If the temperature of the compartment is less than the preset freezing temperature threshold, then reduce the speed of the refrigeration fan.

[0074] It should be noted that in this embodiment, in order to alleviate the condensation phenomenon at the door seal, if the door seal temperature is still lower than the preset door seal dew point temperature after a preset time, the refrigerator can also use a refrigeration fan to alleviate the condensation phenomenon.

[0075] Specifically, for example, a refrigerator can collect the temperature of the freezer compartment while controlling the operation of the freezer fan. If the temperature of that compartment is lower than a preset freezing temperature threshold, the speed of the freezer fan can be reduced.

[0076] Understandably, refrigeration fans can operate at lower speeds while maintaining the temperature of the refrigeration compartment (i.e., the compartment temperature is below the preset refrigeration temperature threshold). For example, for a 7-12V adjustable fan, the speed corresponding to 8.5V voltage can be selected. This reduces the amount of airflow directly blowing from the refrigeration fan onto the compartment door seal, increases the temperature at the door seal, and significantly reduces the probability of condensation on the door seal.

[0077] In another embodiment, the flow of refrigerant into the anti-condensation pipe inside the refrigerator door seal can be controlled simultaneously, and the speed of the refrigeration fan can be reduced to further improve the condensation problem of the door seal, prevent the rubber at the door seal from becoming moldy due to condensation, and also avoid affecting the sealing performance of the door seal.

[0078] In one embodiment, after step S30, "if the target temperature is lower than the preset dew point temperature, adjust the compressor speed and condenser fan speed in the refrigerator until the target temperature is higher than the preset dew point temperature," the following may be included:

[0079] Step S120: Obtain the adjusted rotational speed of the compressor in the refrigerator;

[0080] Step S130: If the adjusted rotation speed is greater than the preset rotation speed threshold and the target temperature is lower than the preset dew point temperature, then increase the starting frequency of the compressor.

[0081] In this embodiment, the refrigerator can also obtain the adjusted rotational speed of the compressor. Furthermore, if the rotational speed is greater than a preset rotational speed threshold and the target temperature of the compressor's suction pipe is lower than the aforementioned preset dew point temperature, the compressor's starting frequency can be increased.

[0082] It should be noted that in this embodiment, when the compressor speed after adjustment is greater than the preset speed threshold, the compressor is in a high-speed operation state. However, if the target temperature of the suction pipe is still lower than the preset dew point temperature (i.e., there is still condensation in the suction pipe), the compressor starting frequency can be increased so that the compressor can run continuously, thereby causing the temperature in the compressor chamber to rise significantly until the target temperature of the suction pipe can exceed the preset dew point temperature.

[0083] It is understandable that in this embodiment, the temperature inside the compressor chamber can be increased by increasing the compressor speed. Since the compressor speed is relatively high, the compressor starting frequency is actually low under the low ambient temperature condition of 25 degrees Celsius. Therefore, when the target temperature of the suction pipe is still lower than the preset dew point temperature, the compressor starting frequency can be increased to further increase the temperature inside the compressor chamber until the target temperature of the suction pipe is still higher than the preset dew point temperature, effectively alleviating the condensation problem on the surface of the suction pipe.

[0084] In one embodiment, after step S10, "obtaining the ambient temperature and humidity of the environment where the refrigerator is located", the method may further include:

[0085] Step S140: Obtain the preset dew point temperature based on the ambient temperature and the ambient humidity;

[0086] Furthermore, after step S20 above, "obtaining the target temperature of the suction pipe of the compressor inside the refrigerator", the following may be included:

[0087] Step S150: If the target temperature is higher than the preset dew point temperature, then control the compressor in the refrigerator to run according to the preset cooling mode;

[0088] Step S160: Adjust the compressor speed and condenser fan speed until the target temperature is lower than the preset dew point temperature.

[0089] In this embodiment, the refrigerator can calculate the preset dew point temperature under the current environment based on the ambient temperature and humidity of its surroundings.

[0090] Based on this, if the refrigerator determines that the target temperature is lower than the preset dew point temperature, according to the above embodiments, a corresponding condensation elimination strategy can be adopted, which will not be elaborated here.

[0091] Additionally, if the refrigerator determines that the target temperature is higher than the preset dew point temperature, it means that there is no risk of condensation in the suction pipe. In this case, the refrigerator can control the compressor to operate normally and perform cooling. However, if the refrigerator detects that the target temperature in the suction pipe exceeds the preset condensation temperature during operation, it can employ anti-condensation strategies.

[0092] In general, such as Figure 3 As shown, the refrigerator can obtain the ambient temperature and humidity of its surroundings through its built-in temperature and humidity sensors. When there is a risk of condensation in the suction pipe, the compressor speed is increased to a preset speed threshold, and the refrigeration fan is controlled to run at a lower speed. Then, after the compressor has been running for a preset time, the condenser fan is turned on and controlled to run at a preset speed.

[0093] This embodiment also provides a refrigerator control device, which can be integrated into the refrigerator. For example, such as... Figure 4 As shown, the refrigerator control device may include:

[0094] The first acquisition module 1001 is used to acquire the ambient temperature and humidity of the environment where the refrigerator is located.

[0098] If the target temperature is lower than the preset dew point temperature, the compressor speed in the refrigerator is increased to the preset speed threshold, and the compressor's running time is obtained.

[0150] Optional, such as Figure 5 As shown, the refrigerator 1100 also includes: a touch screen display 1103, an radio frequency circuit 1104, an audio circuit 1105, an input unit 1106, and a power supply 1107. The processor 1101 is electrically connected to the touch screen display 1103, the radio frequency circuit 1104, the audio circuit 1105, the input unit 1106, and the power supply 1107. Those skilled in the art will understand that... Figure 5 The refrigerator structure shown does not constitute a limitation on the refrigerator and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0151] The touch display screen 1103 can be used to display a graphical user interface (GUI) and receive operation commands generated by the user interacting with the GUI. The touch display screen 1103 may include a display panel and a touch panel. The display panel can be used to display information input by the user or information provided to the user, as well as various GUIs of the refrigerator. These GUIs can be composed of graphics, text, icons, video, and any combination thereof. Optionally, the display panel can be configured using a liquid crystal display (LCD), organic light-emitting diode (OLED), or other similar technologies. The touch panel can be used to collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near the touch panel), and generate corresponding operation commands, which then execute the corresponding program. Optionally, the touch panel may include a touch detection device and a touch controller. The touch detection device detects the user's touch location and the signal generated by the touch operation, transmitting the signal to the touch controller. The touch controller receives touch information from the touch detection device, converts it into touch point coordinates, and sends it to the processor 1101. It can also receive and execute commands from the processor 1101. The touch panel can cover the display panel. When the touch panel detects a touch operation on or near it, it transmits the information to the processor 1101 to determine the type of touch event. Subsequently, the processor 1101 provides corresponding visual output on the display panel based on the type of touch event. In this embodiment, the touch panel and the display panel can be integrated into the touch display screen 1103 to achieve input and output functions. However, in some embodiments, the touch panel and the touch display screen 1103 can be implemented as two independent components to achieve input and output functions. That is, the touch display screen 1103 can also be used as part of the input unit 1106 to achieve input functions.

[0152] The radio frequency circuit 1104 can be used to transmit and receive radio frequency signals to establish wireless communication with network devices or other refrigerators, and to transmit and receive signals with network devices or other refrigerators.

[0153] Audio circuit 1105 can be used to provide an audio interface between the user and the refrigerator via a speaker and a microphone. Audio circuit 1105 can convert received audio data into electrical signals and transmit them to the speaker, where the speaker converts them into sound signals for output. Conversely, the microphone converts collected sound signals into electrical signals, which are then received by audio circuit 1105, converted back into audio data, and then processed by processor 1101 before being transmitted via radio frequency circuit 1104 to, for example, another refrigerator, or output to memory 1102 for further processing. Audio circuit 1105 may also include an earphone jack to provide communication between external headphones and the refrigerator.

[0154] The input unit 1106 can be used to receive input numbers, characters, or user characteristic information (such as fingerprints, iris, facial information, etc.), and to generate keyboard, mouse, joystick, optical, or trackball signal inputs related to user settings and function control.

[0155] Power supply 1107 is used to supply power to the various components of refrigerator 1100. Optionally, power supply 1107 can be logically connected to processor 1101 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system. Power supply 1107 may also include one or more DC or AC power supplies, recharging systems, power fault detection circuits, power converters or inverters, power status indicators, and other arbitrary components.
