[0002] Currently, refrigerators with low-temperature functions on the market generally suffer from problems such as excessively high operating rates, thick frost layers, and poor heat exchange capacity due to their low temperature requirements, large heat loss from the cabinet, and high cooling capacity. When the compressor runs at high frequency for extended periods and cannot reach a shutdown state, the control technology in related fields only calculates the cumulative operating time of the compressor to force it to stop.

[0033] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0034] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.

[0035] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0036] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0037] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0038] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0039] Figure 1 This is a flowchart illustrating a control method for a refrigeration device according to some embodiments of the present disclosure. For example... Figure 1 As shown, the control method includes steps S102 to S108.

[0040] In step S102, the temperature of the compartment of the refrigeration equipment is detected. For example, the temperature of the compartment can be obtained using a temperature sensor of the compartment.

[0041] In step S104, if the temperature of the compartment is greater than the first temperature threshold, it is determined whether the temperature of the compartment is less than or equal to the second temperature threshold, wherein the second temperature threshold is greater than the first temperature threshold.

[0042] Here, the first and second temperature thresholds can be set according to actual needs. For example, they can be adjusted based on the actual operating rate and defrosting status of different refrigerator products under the superfreezing function.

[0043] In some embodiments, the first temperature threshold is less than or equal to the difference between the set temperature and a predetermined value (e.g., 0.5°C).

[0044] In some embodiments, the second temperature threshold is the sum of the first temperature threshold and the first temperature setpoint, wherein the first temperature setpoint is a positive value.

[0045] Here, the first temperature setting value can be set according to actual needs. For example, it can be adjusted based on the actual operating rate and defrosting status of different refrigerator products under the superfreeze function. For example, the range of the first temperature setting value X is 0 < X ​​≤ 2℃. Of course, those skilled in the art will understand that the range of the first temperature setting value is merely exemplary, and the scope of this disclosure is not limited thereto.

[0046] The above step S104 can minimize the problem of the compressor running continuously for a long time without stopping due to reasons such as cold leakage from the casing, compressor aging, or temperature sensor failure, which can lead to a decrease in cooling effect and failure to reach the shutdown point. This reduces the shutdown temperature limit for the compressor.

[0047] In step S106, if the temperature of the compartment is less than or equal to the second temperature threshold, it is determined whether the first cumulative running time of the compressor of the refrigeration equipment is greater than or equal to the first time threshold, starting from the time when the temperature of the compartment meets the condition of being less than or equal to the second temperature threshold.

[0048] In other words, timing begins from when the temperature of the compartment is less than or equal to the second temperature threshold to obtain the first cumulative running time of the compressor, and it is determined whether the first cumulative running time of the compressor is greater than or equal to the first time threshold.

[0049] Here, the first time threshold can be set according to actual needs. For example, it can be adjusted based on the actual operating rate and defrosting status of different refrigerator products under the superfreeze function. For example, the range of the first time threshold Y is 0 < Y ≤ 200 minutes. Of course, those skilled in the art will understand that the range of this first time threshold is merely exemplary, and the scope of this disclosure is not limited thereto.

[0050] In embodiments of this disclosure, statistical timing can be performed based on the timer of the controller of the refrigeration equipment.

[0051] In step S108, if the first cumulative running time of the compressor is greater than or equal to the first time threshold, the compressor is controlled to stop.

[0052] Therefore, a control method for a refrigeration device according to some embodiments of the present disclosure is provided. The control method includes: detecting the temperature of a compartment in the refrigeration device; if the temperature of the compartment is greater than a first temperature threshold, determining whether the temperature of the compartment is less than or equal to a second temperature threshold, wherein the second temperature threshold is greater than the first temperature threshold; if the temperature of the compartment is less than or equal to the second temperature threshold, determining whether a first cumulative running time of the compressor, starting from the point where the temperature of the compartment begins to be less than or equal to the second temperature threshold, is greater than or equal to a first time threshold; and if the first cumulative running time of the compressor is greater than or equal to the first time threshold, controlling the compressor of the refrigeration device to shut down. This method can reduce the problem of long-term high-frequency low-temperature operation of the refrigeration device, thereby reducing the operating rate of the refrigeration device.

[0053] In some embodiments, the control method further includes controlling the compressor to operate when the first cumulative operating time of the compressor is less than a first time threshold. In this embodiment, the first cumulative operating time of the compressor being less than the first time threshold indicates that the first cumulative operating time of the compressor is not yet too long and can continue to operate, thereby not affecting the refrigeration operation of the refrigeration equipment.

[0054] In some embodiments, the control method further includes controlling the compressor to operate when the temperature of the compartment is greater than a second temperature threshold. In this embodiment, the temperature of the compartment being greater than the second temperature threshold indicates that the current temperature of the compartment is still relatively high, requiring the refrigeration equipment to continue operating. Therefore, the compressor is controlled to continue operating so as not to affect the refrigeration operation of the refrigeration equipment.

[0055] In some embodiments, the control method further includes: controlling the compressor to stop when the temperature of the compartment is less than or equal to a first temperature threshold (also referred to as a shutdown temperature threshold). In this embodiment, the temperature of the compartment being less than or equal to the first temperature threshold indicates that the current temperature of the compartment has met the requirement of being less than or equal to the shutdown temperature threshold, thus controlling the compressor to stop and preventing the compressor from operating at high frequency and low temperature for a long period of time.

[0056] Figure 2 This is a flowchart illustrating a control method for a refrigeration device according to other embodiments of this disclosure. For example... Figure 2 As shown, the control method includes steps S202 to S210. For example, the control method can be implemented under the superfreezing function of a refrigeration device (e.g., a refrigerator).

[0057] In step S202, it is determined whether the temperature of the compartment is less than or equal to a first temperature threshold. If so, the process proceeds to step S210; otherwise, the process proceeds to step S204.

[0058] In step S204, it is determined whether the temperature of the compartment is less than or equal to the second temperature threshold. If so, the process proceeds to step S206; otherwise, the process proceeds to step S208.

[0059] In step S206, it is determined whether the first cumulative running time of the compressor is greater than or equal to a first time threshold. If so, the process proceeds to step S210; otherwise, the process proceeds to step S208. Here, the first cumulative running time of the compressor is obtained from the time the temperature of the compartment begins to meet the condition of being less than or equal to a second temperature threshold.

[0060] In step S208, the compressor is controlled to operate.

[0061] In step S210, the compressor is stopped.

[0062] Thus, a control method for a refrigeration device according to other embodiments of the present disclosure is provided. In this method, the required temperature of the compartment of the refrigeration device is determined, and the operating time within its temperature range is recorded to control whether the device needs to be shut down. This control method can improve the reliability of the refrigeration device under high-frequency low-temperature operation with superfreezing function.

[0063] The inventors of this disclosure have discovered that in related technologies, refrigeration equipment (e.g., refrigerators) suffers from severe frost buildup on the evaporator due to prolonged low-temperature operation, resulting in poor heat exchange and further exacerbating the problem of high operating rates, thus affecting the reliability of refrigerator operation.

[0064] In view of this, embodiments of the present disclosure also provide a control method for refrigeration equipment to optimize defrosting control and improve the reliability of refrigeration equipment operation.

[0065] Figure 3 This is a flowchart illustrating a control method for a refrigeration device according to other embodiments of this disclosure. For example... Figure 3 As shown, the control method includes steps S302 to S304.

[0066] In step S302, it is determined whether the cumulative defrosting interval time of the refrigeration equipment is greater than or equal to the second time threshold. Here, the cumulative defrosting interval time of the refrigeration equipment refers to the cumulative interval time from the end of the last defrosting of the refrigeration equipment to the current moment.

[0067] Here, the second time threshold can be set according to actual needs. For example, it can be adjusted based on the actual operating rate and defrosting status of different refrigerator products under the superfreezing function. For example, the range of the second time threshold S is 720 minutes ≤ S ≤ 5760 minutes. Of course, those skilled in the art will understand that the range of this second time threshold is merely exemplary, and the scope of this disclosure is not limited thereto.

[0068] In step S304, if the cumulative defrosting interval time of the refrigeration equipment is less than the second time threshold, it is determined whether the refrigeration equipment needs to be controlled to enter the defrosting mode based on the temperature of the compartment and the second cumulative running time of the compressor.

[0069] In some embodiments, step S304 includes: if the cumulative defrosting interval time of the refrigeration equipment is less than a second time threshold, determining whether the temperature of the compartment is less than or equal to a third temperature threshold, wherein the third temperature threshold is greater than a first temperature threshold; if the temperature of the compartment is less than or equal to the third temperature threshold, determining whether the second cumulative running time of the compressor is greater than or equal to the third time threshold starting from the point where the temperature of the compartment meets the condition of being less than or equal to the third temperature threshold; if the second cumulative running time of the compressor is greater than or equal to the third time threshold, determining whether the temperature of the compartment is greater than or equal to a fourth temperature threshold, wherein the fourth temperature threshold is less than the third temperature threshold and greater than the first temperature threshold; and if the temperature of the compartment is greater than or equal to the fourth temperature threshold, controlling the refrigeration equipment to enter defrosting mode.

[0070] In the above embodiments, if the temperature of the compartment is greater than or equal to the fourth temperature threshold, it indicates that after the compressor has accumulated a running time exceeding (greater than or equal to) the third time threshold, the temperature of the compartment of the refrigeration equipment has not reached the expected low temperature. This is likely because the refrigeration equipment has been running at a low temperature for a long time, resulting in severe frost buildup on the evaporator and thus poor heat exchange performance. Therefore, the refrigeration equipment is controlled to enter defrost mode for defrosting at this time.

[0071] Here, the defrosting mode is a known defrosting mode. After entering the defrosting mode, the refrigeration equipment will perform defrosting operations, such as stopping the compressor and turning on the electric heater.

[0072] In this step, the required room temperature for the refrigeration equipment is determined, and the operating time within that temperature range is recorded to control whether defrosting is necessary. This control method allows the refrigeration equipment to determine defrosting conditions more accurately based on actual needs.

[0073] Thus, a control method for a refrigeration device according to other embodiments of this disclosure is provided. The control method further includes: determining whether the cumulative defrost interval time of the refrigeration device is greater than or equal to a second time threshold; and, if the cumulative defrost interval time of the refrigeration device is less than the second time threshold, determining whether it is necessary to control the refrigeration device to enter a defrost mode based on the compartment temperature and the second cumulative operating time of the compressor. This control method enables the refrigeration device to determine the defrost entry conditions more closely according to actual needs, optimizes defrost control, and improves the reliability of the refrigeration device operation.

[0074] In some embodiments, the control method further includes: controlling the refrigeration equipment to enter a defrost mode when the cumulative defrost interval time of the refrigeration equipment is greater than or equal to a second time threshold. In this embodiment, the fact that the cumulative defrost interval time of the refrigeration equipment is greater than or equal to the second time threshold indicates that the refrigeration equipment has not defrosted for a relatively long time. Therefore, controlling the refrigeration equipment to enter a defrost mode does not affect the operation of the refrigeration equipment.

[0075] In some embodiments, step S304 further includes: controlling the refrigeration equipment to maintain refrigeration operation when the temperature of the compartment is greater than a third temperature threshold. In this embodiment, the temperature of the compartment being greater than the third temperature threshold indicates that the current temperature of the compartment is still relatively high; therefore, controlling the refrigeration equipment to maintain refrigeration operation does not affect the operation of the refrigeration equipment.

[0076] In some embodiments, step S304 further includes: controlling the refrigeration equipment to maintain refrigeration operation when the second cumulative operating time of the compressor is less than a third time threshold. In this embodiment, the second cumulative operating time of the compressor being less than the third time threshold indicates that the cumulative operating time of the compressor at low temperatures is not yet very long, therefore the refrigeration equipment is controlled to maintain refrigeration operation, thereby not affecting the operation of the refrigeration equipment.

[0077] In some embodiments, step S304 further includes: controlling the refrigeration equipment to maintain refrigeration operation when the temperature of the compartment is less than a fourth temperature threshold. In this embodiment, the temperature of the compartment being less than the fourth temperature threshold indicates that after the compressor has accumulated an operating time exceeding (greater than or equal to) a third time threshold, the temperature of the compartment of the refrigeration equipment can reach the expected low temperature. At this point, it is considered that the evaporator frost is not severe, so defrosting is not required, and therefore the refrigeration equipment is controlled to maintain refrigeration operation.

[0078] Figure 4 This is a flowchart illustrating a control method for a refrigeration device according to other embodiments of this disclosure. For example... Figure 4 As shown, the control method includes steps S402 to S412.

[0079] In step S402, it is determined whether the cumulative defrosting interval time of the refrigeration equipment is greater than or equal to the second time threshold. If so, the process proceeds to step S412; otherwise, the process proceeds to step S404.

[0080] In step S404, it is determined whether the temperature of the compartment is less than or equal to the third temperature threshold. If so, the process proceeds to step S406; otherwise, the process proceeds to step S410.

[0081] In some embodiments, the third temperature threshold is the sum of the first temperature threshold and the second temperature setting value, wherein the second temperature setting value is a positive value.

[0082] Here, the second temperature setting can be set according to actual needs. For example, it can be adjusted based on the actual operating rate and defrosting status of different refrigerator products under the superfreezing function. For example, the range of the second temperature setting V is Q < V ≤ 4℃, where Q is the third temperature setting value. Of course, those skilled in the art will understand that the range of this second temperature setting value is merely exemplary, and the scope of this disclosure is not limited thereto.

[0083] The above step S404 can minimize the problem of excessive frost on the evaporator during low-temperature operation of refrigeration equipment, which leads to poor heat exchange, prevents the refrigeration equipment from reaching the shutdown point, and causes the compressor to run continuously for a long time.

[0084] In step S406, it is determined whether the compressor's second cumulative running time is greater than or equal to the third time threshold. If so, the process proceeds to step S408; otherwise, the process proceeds to step S410. Here, the compressor's second cumulative running time is obtained from the time the temperature of the compartment begins to meet the condition of being less than or equal to the third temperature threshold.

[0085] Here, the third time threshold can be set according to actual needs. For example, it can be adjusted based on the actual operating rate and defrosting status of different refrigerator products under the superfreeze function. For example, the range of the third time threshold K is 0 < K ≤ 200 minutes. Of course, those skilled in the art will understand that the range of this third time threshold is merely exemplary, and the scope of this disclosure is not limited thereto.

[0086] In step S408, it is determined whether the temperature of the compartment is greater than or equal to the fourth temperature threshold. If so, the process proceeds to step S412; otherwise, the process proceeds to step S410.

[0087] In some embodiments, the fourth temperature threshold is the sum of the first temperature threshold and the third temperature setting value, wherein the third temperature setting value is a positive value.

[0088] Here, the third temperature setting can be set according to actual needs. For example, it can be adjusted based on the actual operating rate and defrosting status of different refrigerator products under the superfreeze function. For example, the range of the third temperature setting Q is 0 < Q ≤ 2℃. Of course, those skilled in the art will understand that this range of the third temperature setting is merely exemplary, and the scope of this disclosure is not limited thereto.

[0089] In step S410, the refrigeration equipment is controlled to maintain refrigeration operation.

[0090] In step S412, the refrigeration equipment is controlled to enter defrost mode.

[0091] Thus, a control method for a refrigeration device according to other embodiments of the present disclosure is provided. In this control method, the required room temperature of the refrigeration device is determined, and the operating time within its temperature range is recorded to control whether defrosting is required. This control method allows the refrigeration device to determine defrosting conditions more accurately based on actual needs, optimizes defrosting control, and improves the reliability of the refrigeration device's operation.

[0092] In some embodiments, in defrosting mode, the compressor can be stopped during the defrosting process (e.g., when the electric heater is turned on). At this time, the operating status of the compressor can be re-determined, and the defrosting status control can also be re-determined after defrosting is completed.

[0093] In the embodiments of this disclosure, under the high-frequency and low-temperature operation of the refrigerator's superfreezing function, by increasing the determination of the compartment temperature operating range and the compressor's cumulative operating time, the compressor's start / stop and defrost requests are controlled, thereby realizing scenario-based refrigerator start / stop and defrost control and improving the long-term operational reliability of the refrigerator under high-frequency and low-temperature conditions.

[0094] Figure 5 This is a structural block diagram illustrating a control device for a refrigeration equipment according to some embodiments of the present disclosure. Figure 5 As shown, the control device includes a detection unit 510 and a control processing unit 520.

[0095] The detection unit 510 is used to detect the temperature of the compartment of the refrigeration equipment.

[0096] The control processing unit 520 is used to determine whether the temperature of the compartment is less than or equal to a second temperature threshold when the temperature of the compartment is greater than a first temperature threshold, wherein the second temperature threshold is greater than the first temperature threshold. When the temperature of the compartment is less than or equal to the second temperature threshold, it determines whether the first cumulative running time of the compressor of the refrigeration equipment is greater than or equal to a first time threshold from the time the temperature of the compartment begins to meet the condition of being less than or equal to the second temperature threshold. When the first cumulative running time of the compressor is greater than or equal to the first time threshold, it controls the compressor to stop.

[0097] Thus, a control device for a refrigeration equipment according to some embodiments of the present disclosure is provided. This control device can reduce the problem of long-term high-frequency, low-temperature operation of the refrigeration equipment, thereby reducing the operating rate of the refrigeration equipment.

[0102] In some embodiments, the control processing unit 520 is further configured to: determine whether the cumulative defrosting interval time of the refrigeration equipment is greater than or equal to a second time threshold; and if the cumulative defrosting interval time of the refrigeration equipment is less than the second time threshold, determine whether it is necessary to control the refrigeration equipment to enter the defrosting mode based on the temperature of the compartment and the second cumulative running time of the compressor.

[0104] In some embodiments, the control processing unit 520 is further configured to control the refrigeration equipment to enter the defrosting mode when the cumulative defrosting interval time of the refrigeration equipment is greater than or equal to a second time threshold.
