Description

Technical Field

[0001] This disclosure relates to the field of refrigerator equipment technology, and in particular to a method, device, equipment and storage medium for temperature control of a refrigerator tilting beam. Background Technology

[0002] Currently, double-door refrigerators feature a column structure, with each door sealing against the column when closed. This column structure can be a flip-up beam. However, during refrigerator operation, the significant temperature difference between the refrigerator compartment and the outside environment causes condensation to easily form on the surface of the column structure (i.e., the flip-up beam). Related technologies use heaters to raise the surface temperature of the flip-up beam above the dew point temperature, thus preventing condensation. However, these heaters typically have high power, resulting in higher interference voltage and power, which reduces the refrigerator's EMC (Electromagnetic Compatibility) test compliance rate.

[0035] Figure 4 This is a block diagram illustrating an electronic device according to some embodiments of the present disclosure. Detailed Implementation

[0036] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0037] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0038] Currently, double-door refrigerators have a column structure, with each door sealing against the column when closed. This column structure can be a flip-up beam. However, during refrigerator operation, the significant temperature difference between the refrigerator compartment and the outside environment causes condensation to easily form on the surface of the column structure (i.e., the flip-up beam). Related technologies can use a heater to raise the surface temperature of the flip-up beam above its dew point temperature, thereby preventing condensation.

[0039] However, in related technologies, the temperature of the tilting beam can be controlled by controlling the operating time of the tilting beam heater. In this case, the tilting beam heater operates with a fixed heating power and a relatively high heating voltage (e.g., 12V). When the heater is started via a transistor switch, if the heating voltage is too high, high-frequency voltage fluctuations may occur between the drain and source of the transistor, increasing the interference voltage and power generated by the refrigerator, thereby reducing the compliance rate of the refrigerator's electromagnetic compatibility test.

[0040] Therefore, it is evident that how to reduce the interference voltage and power generated by the refrigerator while meeting the anti-condensation function, so as to improve the compliance rate of the refrigerator's electromagnetic compatibility test, is a key technical problem that urgently needs to be solved.

[0041] To address the aforementioned technical problems, the inventors proposed the following technical concept: First, the initial heating voltage of the heater is determined by calculating the dew point temperature. Then, an optimization logic that gradually increases the initial voltage is used to find the minimum heating voltage that can meet the anti-condensation conditions. The heater is then controlled to operate at the minimum heating voltage, which reduces the interference voltage and interference power generated by the refrigerator. This overcomes the limitations of the traditional method of controlling the heater by adjusting the duty cycle (i.e., the heating time within a heating cycle) with a fixed voltage.

[0042] The specific steps may include: First, acquiring the external ambient temperature, external ambient humidity, and a first internal temperature of the refrigerator compartment; determining the dew point temperature corresponding to the refrigerator's flip-up beam based on the external ambient temperature and humidity, and determining a first heating voltage corresponding to the flip-up beam based on the dew point temperature. The first heating voltage is the minimum heating voltage of the flip-up beam at the dew point temperature. Then, controlling the heater of the flip-up beam to operate at the first heating voltage for a first preset time to acquire a second internal temperature of the refrigerator compartment. Finally, based on the first and second internal temperatures, determining whether the first heating voltage meets preset anti-condensation conditions. If not, gradually increasing the first heating voltage to obtain a second heating voltage that meets the preset anti-condensation conditions, and controlling the heater to operate at the second heating voltage.

[0043] In this embodiment, the dew point temperature corresponding to the refrigerator's flip beam is first determined based on the external ambient temperature and humidity. Then, the minimum first heating voltage of the flip beam at that dew point temperature is determined. Subsequently, the second heating voltage that meets the preset anti-condensation conditions is obtained by gradually increasing the first heating voltage. The second heating voltage is obtained by gradually increasing the minimum first heating voltage. Under the condition of meeting the preset anti-condensation conditions, the voltage value of the second heating voltage can be reduced to the maximum extent, thereby reducing the interference voltage and interference power generated by the refrigerator. Therefore, it helps to improve the compliance rate of the refrigerator's electromagnetic compatibility test.

[0044] To enable those skilled in the art to better understand the present disclosure, the present disclosure will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] Figure 1 This is a flowchart illustrating a method for controlling the temperature of a refrigerator tilting beam according to some embodiments of this disclosure, such as... Figure 1 As shown, the method includes:

[0046] S101. Obtain the external ambient temperature, external ambient humidity, and first internal temperature of the refrigerator compartment.

[0047] In this embodiment, the external ambient temperature and humidity of the refrigerator can be obtained using a temperature sensor and a humidity sensor disposed on the outside of the refrigerator; a first internal temperature of the refrigerator compartment can be obtained using a temperature sensor disposed inside the refrigerator compartment. Optionally, the measurement error of the temperature sensor is less than a preset error threshold. The value of the preset error threshold is not specifically limited in this embodiment. For example, the preset error threshold may be 0.05℃, 0.1℃, or 0.2℃.

[0048] For example, such as Figure 2 As shown, the external ambient temperature of the refrigerator can be represented as Ta, and the first internal temperature of the refrigerator compartment can be represented as Tc.

[0049] S102. Determine the dew point temperature corresponding to the refrigerator's flip beam based on the external ambient temperature and humidity, and determine the first heating voltage corresponding to the flip beam based on the dew point temperature. The first heating voltage is the minimum heating voltage of the flip beam at the dew point temperature.

[0050] In some embodiments, the dew point temperature corresponding to the refrigerator's flip beam can be determined according to the external ambient temperature and humidity using the following formula 1.

[0051] Formula 1: ;

[0052] Where Tx represents the dew point temperature, t represents the ambient temperature, and R... H This represents the ambient humidity, 1n represents the natural logarithm, and a and b are preset constants. For example, a is 17.27 and b is 237.7.

[0053] In some embodiments, determining the first heating voltage corresponding to the flip beam based on the dew point temperature includes: determining the first heating voltage corresponding to the flip beam from a pre-stored correspondence between dew point temperature and heating voltage based on the dew point temperature.

[0054] Optionally, the above correspondence can be a table showing the relationship between dew point temperature and heating voltage. The table can be consulted based on the dew point temperature to determine the first heating voltage corresponding to the tilting beam. The heating voltage in the table can be the minimum heating voltage required to prevent condensation on the tilting beam at the dew point temperature, and can be obtained experimentally.

[0055] In other embodiments, determining the first heating voltage corresponding to the flip beam based on the dew point temperature includes: determining the target temperature corresponding to the flip beam based on the dew point temperature, determining the minimum heating power of the flip beam to maintain the target temperature, and determining the first heating voltage corresponding to the flip beam based on the minimum heating power.

[0056] Optionally, the target temperature corresponding to the tilting beam can be equal to the dew point temperature. The minimum heating power required to maintain the target temperature can be equal to the heat dissipation power of the tilting beam. The heat dissipation power of the tilting beam can be determined based on the heat dissipation coefficient of the tilting beam and the temperature difference between the target temperature and the internal temperature of the refrigerator compartment.

[0057] In this embodiment of the disclosure, by obtaining the minimum heating voltage of the flip beam at the dew point temperature, the limitation of controlling the heater by adjusting the duty cycle (i.e., the heating time within a heating cycle) with a fixed voltage in the traditional method is overcome. This provides an initial heating voltage for finding the second heating voltage that meets the preset anti-condensation conditions, thus helping to minimize the interference voltage and interference power generated by the refrigerator.

[0058] S103. Control the heater of the tilting beam to operate at a first heating voltage for a first preset time to obtain the second internal temperature of the cold storage compartment.

[0059] In this embodiment of the disclosure, the value of the first preset duration is not specifically limited. For example, the first preset duration may be 30 seconds, 60 seconds, or 90 seconds.

[0060] In some embodiments, the value of the first preset duration can be adjusted according to the refrigerator's operating status. Optionally, the refrigerator's door opening frequency and / or door opening duration can be obtained, and the value of the first preset duration can be adjusted according to the door opening frequency and / or door opening duration. For example, when the refrigerator's door opening frequency is greater than the preset door opening frequency, the value of the first preset duration can be reduced to reduce the impact of excessively high door opening frequency on the internal temperature of the refrigerator compartment and improve the accuracy of the second internal temperature. In the embodiments of this disclosure, the value of the preset door opening frequency is not specifically limited.

[0061] S104. Based on the first internal temperature and the second internal temperature, determine whether the first heating voltage meets the preset anti-condensation condition. If not, gradually increase the first heating voltage to obtain a second heating voltage that meets the preset anti-condensation condition, and control the heater to operate at the second heating voltage.

[0062] In this embodiment, a preset anti-condensation condition is used to limit the minimum heating voltage to prevent condensation from occurring on the tilting beam. At this time, the heating power of the heater is greater than or equal to the heat dissipation power of the tilting beam.

[0063] Optionally, the preset anti-condensation condition may be: the internal temperature of the refrigerator compartment (second internal temperature) is not less than the internal temperature of the refrigerator compartment before the tilting beam heater is operated (first internal temperature). Accordingly, based on the first internal temperature and the second internal temperature, determining whether the first heating voltage meets the preset anti-condensation condition includes: if the first internal temperature is less than or equal to the second internal temperature, then determining that the first heating voltage meets the preset anti-condensation condition; if the first internal temperature is greater than the second internal temperature, then determining that the first heating voltage does not meet the preset anti-condensation condition.

[0064] In some embodiments, the method further includes: if the first heating voltage meets the preset anti-condensation condition, then the first heating voltage is determined as the second heating voltage.

[0065] In this embodiment of the disclosure, the lowest voltage that meets the preset anti-condensation conditions is found by using the condition that the internal temperature of the refrigerator compartment (second internal temperature) is not less than the internal temperature of the refrigerator compartment before the operation of the flip beam heater (first internal temperature). This helps to minimize the interference voltage and interference power generated by the refrigerator.

[0066] In some embodiments, the first heating voltage can be gradually adjusted based on the comparison of internal temperatures before and after heating. Optionally, gradually increasing the first heating voltage to obtain a second heating voltage that meets the preset anti-condensation conditions includes: increasing the first heating voltage by a first preset voltage value to obtain an intermediate heating voltage; controlling the heater of the tilting beam to operate at the intermediate heating voltage for a first preset time to obtain a third internal temperature of the cold storage compartment; determining whether the intermediate heating voltage meets the preset anti-condensation conditions based on the first internal temperature and the third internal temperature; if it does, determining the intermediate heating voltage as the second heating voltage; if it does not, continuing to increase the first heating voltage until the intermediate heating voltage meets the preset anti-condensation conditions, and then determining the intermediate heating voltage as the second heating voltage.

[0067] For example, such as Figure 2As shown, after the heater of the control tilting beam has been running for a first preset time, it is determined whether the internal temperature of the refrigerator compartment before heating (i.e., the first internal temperature Tc) is less than the current internal temperature of the refrigerator compartment (i.e., the second internal temperature Tc1). If it is less, it is determined that the preset anti-condensation condition is met, and the intermediate heating voltage is determined as the second heating voltage; if it is not less, it is determined that the preset anti-condensation condition is not met, and the first heating voltage is increased. The first preset voltage value increased each time can be 0.2V. At this time, the intermediate heating voltage can be expressed as Vf = N + 0.2(M - 1); where N represents the first heating voltage and M represents the number of adjustments.

[0068] In this embodiment of the present disclosure, a second heating voltage that meets the preset anti-condensation conditions is obtained by gradually increasing the first heating voltage. This allows the voltage value of the second heating voltage to be reduced to the maximum extent while meeting the preset anti-condensation conditions. Therefore, it helps to reduce the interference voltage and interference power generated by the refrigerator, thereby improving the compliance rate of the refrigerator's electromagnetic compatibility test.

[0069] In some embodiments, the first preset voltage value is used to represent the adjustment step size of the first voltage value, which can be determined according to the external ambient humidity. Optionally, before increasing the first heating voltage by the first preset voltage value to obtain an intermediate heating voltage, the method further includes: determining a first preset voltage value that matches the external ambient humidity from a correspondence between humidity and preset voltage values; wherein the humidity in the correspondence is negatively correlated with the first preset voltage value.

[0070] For example, when the external humidity is high (such as during the rainy season), a smaller voltage adjustment step size (such as 0.1V) can be used to improve tuning accuracy; when the external humidity is low (such as during the dry season), a larger voltage adjustment step size (such as 0.3V) can be used to improve tuning efficiency.

[0071] In this embodiment of the disclosure, since humidity is negatively correlated with the first preset voltage value, when the external ambient humidity is high, a smaller voltage adjustment step size can be used to improve the tuning efficiency; when the external ambient humidity is low, a larger voltage adjustment step size can be used to improve the tuning efficiency, thus achieving a balance between adjustment accuracy and adjustment efficiency, ensuring both the accuracy and efficiency of voltage regulation.

[0072] In some embodiments, during the voltage optimization process, key indicators of electromagnetic compatibility testing (such as disturbance voltage and disturbance power) can be monitored. When an increase in electromagnetic compatibility testing interference is detected, the voltage adjustment step size can be reduced to suppress harmonic interference; when a low level of electromagnetic compatibility testing interference is detected, the voltage adjustment step size can be increased to improve regulation efficiency.

[0073] Optionally, the method further includes: during the process of gradually increasing the first heating voltage based on the first internal temperature and the second internal temperature to obtain a second heating voltage that meets the preset anti-condensation conditions, monitoring the disturbance voltage and disturbance power of the refrigerator; if the disturbance voltage is greater than the first preset voltage threshold and / or the disturbance power is greater than the first preset power threshold, then adjusting the first preset voltage value to the second preset voltage value, wherein the second preset voltage value is lower than the first preset voltage value; if the disturbance voltage is less than the second preset voltage threshold and the disturbance power is less than the second preset power threshold, then adjusting the first preset voltage value to the third preset voltage value, wherein the first preset voltage value is lower than the third preset voltage value.

[0074] In this embodiment of the disclosure, the values ​​of the first preset voltage threshold, the second preset voltage threshold, the first preset power threshold, the second preset power threshold, the second preset voltage value, and the third preset voltage value are not specifically limited.

[0075] This disclosure provides a method for temperature control of a refrigerator's flip beam: acquiring the external ambient temperature, external ambient humidity, and a first internal temperature of the refrigerator compartment; determining the dew point temperature corresponding to the flip beam based on the external ambient temperature and external ambient humidity, and determining a first heating voltage corresponding to the flip beam based on the dew point temperature, wherein the first heating voltage is the minimum heating voltage of the flip beam at the dew point temperature; controlling the heater of the flip beam to operate at the first heating voltage for a first preset time to acquire a second internal temperature of the refrigerator compartment; determining whether the first heating voltage meets a preset anti-condensation condition based on the first and second internal temperatures, and if not, gradually increasing the first heating voltage to obtain a second heating voltage that meets the preset anti-condensation condition, and controlling the heater to operate at the second heating voltage. In this embodiment, the dew point temperature corresponding to the refrigerator's flip beam is first determined based on the external ambient temperature and humidity. Then, the minimum first heating voltage of the flip beam at that dew point temperature is determined. Subsequently, the second heating voltage that meets the preset anti-condensation conditions is obtained by gradually increasing the first heating voltage. The second heating voltage is obtained by gradually increasing the minimum first heating voltage. Under the condition of meeting the preset anti-condensation conditions, the voltage value of the second heating voltage can be reduced to the maximum extent, thereby reducing the interference voltage and interference power generated by the refrigerator. Therefore, it helps to improve the compliance rate of the refrigerator's electromagnetic compatibility test.
