Description

Technical Field

[0001] The present disclosure relates to the field of equipment control in the refrigerator industry, and particularly to an equipment control method, an equipment control device, and a storage medium. Background Art

[0002] The refrigerator detects the internal temperature through a temperature sensor arranged on the side wall of its inner liner, and controls the operation of the refrigerator compressor according to the temperature detected by the temperature sensor, so as to control the temperature inside the refrigerator within a certain range, and realize the refrigeration of various foods inside the refrigerator.

[0003] In the related art, the refrigerator is provided with a startup point parameter and a shutdown point parameter. When the sensed temperature of the space temperature sensor inside the refrigerator reaches the startup point parameter, the compressor and the blower are started for cooling; when the sensed temperature of the space temperature sensor inside the refrigerator reaches the shutdown point parameter, the compressor and the blower are turned off for heating, and the temperature inside the refrigerator is controlled within a certain range in the above manner. However, when a large amount of food is stored in the refrigerator compartment, the space temperature sensor inside the refrigerator can only sense the local temperature, resulting in misjudgment of the overall temperature in the compartment, causing the low-temperature time in the compartment to be too long and frozen vegetables to be produced. Summary of the Invention

The first duration and the second duration are determined in the following manner: determine the current ambient temperature, determine the first duration according to the corresponding relationship between the current ambient temperature and the first duration, and determine the second duration according to the corresponding relationship between the current ambient temperature and the second duration.

[0010] In one implementation, the method further includes: in response to the completion of cooling the inside of the warehouse, turning off the first temperature control mode and enabling the second temperature control mode to maintain the temperature inside the warehouse. In the second temperature control mode, the temperature inside the warehouse is maintained in the following manner:

[0011] In response to the currently detected temperature being greater than the first temperature threshold, start cooling; in response to the currently detected temperature being less than the second temperature threshold, stop cooling.

[0012] According to a second aspect of the embodiments of the present disclosure, there is provided a device control device, including: a determination unit configured to determine the currently detected temperature detected by a temperature sensor inside the warehouse of a refrigeration device and determine a first temperature threshold corresponding to the current gear of the refrigeration device. The first temperature threshold is the upper limit of the detected temperature range corresponding to the refrigeration device at the current gear, and different gears of the refrigeration device correspond to different detected temperature ranges; a processing unit configured to, in response to the difference between the currently detected temperature and the first temperature threshold being greater than a difference threshold, control the refrigeration device to cool the inside of the warehouse using a first temperature control mode. In the first temperature control mode, the processing unit cyclically and alternately executes the start and stop of cooling according to different maintenance durations, and the start and stop of cooling correspond to different maintenance durations respectively.

[0013] In one implementation, the processing unit controls the refrigeration device to cool the interior of the storage compartment in the first temperature control mode as follows: determining a second temperature threshold corresponding to the current gear of the refrigeration device, and determining the current detected temperature of the refrigeration device in real time, where the second temperature threshold is the lower limit of the detected temperature range corresponding to the refrigeration device in the current gear; and controlling the execution of the first temperature control mode according to the second temperature threshold and the current detected temperature.

[0014] In one implementation, the processing unit controls the execution of the first temperature control mode according to the second temperature threshold and the current detected temperature as follows: in response to the current detected temperature being greater than the second temperature threshold, maintaining the first temperature control mode to cool the interior of the storage compartment; and in response to the current detected temperature being less than the second temperature threshold, turning off the first temperature control mode.

[0015] In one implementation, the processing unit alternately executes cooling on and cooling off in cycles according to different maintenance durations: after cooling on is maintained for a first duration, cooling off is maintained for a second duration; and cooling on and cooling off are alternately executed in cycles.

[0016] In one implementation, the first duration and the second duration have a corresponding relationship with the ambient temperature. The first duration is positively correlated with the ambient temperature, and the second duration is negatively correlated with the ambient temperature. The first duration and the second duration are determined by the processing unit as follows: determining the current ambient temperature, determining the first duration according to the corresponding relationship between the current ambient temperature and the first duration, and determining the second duration according to the corresponding relationship between the current ambient temperature and the second duration.

[0017] In one implementation, the processing unit is further configured to: in response to the completion of cooling the interior of the storage compartment, turn off the first temperature control mode and enable the second temperature control mode to maintain the temperature inside the storage compartment. In the second temperature control mode, the temperature inside the storage compartment is maintained as follows: in response to the current detected temperature being greater than the first temperature threshold, cooling on is enabled; and in response to the current detected temperature being less than the second temperature threshold, cooling off is enabled.

[0018] According to a third aspect of the embodiments of the present disclosure, there is provided a device control device, including: a processor; and a memory for storing processor-executable instructions; wherein the processor is configured to: execute the device control method described in the first aspect or any one of the implementations of the first aspect.

[0020] The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects: determining the detected temperature detected by the temperature sensor of the refrigeration device, and determining the upper limit of the detected temperature range of the refrigeration device at the current gear. When the difference between the detected temperature and the first temperature threshold is greater than the difference threshold, a temperature control mode of alternately executing cooling on and off is used to cool the inside of the warehouse. Through the present disclosure, after placing the items to be refrigerated in the refrigeration device, according to different maintenance durations, the detected temperature of the refrigeration device is reduced to the refrigeration temperature by alternately executing cooling on and off in a cycle. By turning off the cooling after cooling for a period of time, the overall temperature inside the warehouse is synchronously reduced, avoiding the adverse effect on the items to be refrigerated caused by the local temperature where the temperature sensor is located being higher than that of other parts and continuously cooling, resulting in too low temperature of other parts inside the warehouse, and ensuring the refrigeration effect of the refrigeration device.

[0035] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure.

[0036] The device control method provided by the embodiments of the present disclosure is applied to the scenario of controlling the temperature in the cold storage device compartment after placing the items to be refrigerated in the cold storage device.

[0037] When the cold storage device performs temperature control, the temperature inside the cold storage device compartment is detected by a temperature sensor provided inside the cold storage device compartment, and the refrigeration device (compressor and blower) provided inside the cold storage device compartment cools down or maintains the temperature according to the temperature detected by the temperature sensor, so as to realize the refrigeration of the items inside the compartment.

[0038] In the related art, the cold storage device is provided with a start-up point parameter and a shutdown point parameter. When the sensed temperature of the space temperature sensor in the cold storage device (refrigerator) reaches the start-up point parameter, the compressor and the blower are started to cool down; when the sensed temperature of the space temperature sensor in the cold storage device reaches the shutdown point parameter, the compressor and the blower are turned off to heat up, and the temperature inside the cold storage device is controlled within a certain range in the above manner.

[0039] In one example, a temperature control method in the related art is proposed. The temperature is controlled according to the gear of the refrigeration device, the current ambient temperature, and the temperature detected by the temperature sensor, so that the temperature inside the compartment is maintained within a certain range. The partial control logic of this method is shown in the following table:

[0040]

[0041] As shown in the above table, on the premise that the range of the refrigeration equipment is at the first gear, the expected temperature (corresponding temperature) in the refrigeration equipment compartment is 2°C. When the ambient temperature is between 11 - 17°C (i.e., 11°C ≤ ambient temperature < 17°C), the ON parameter of the refrigeration device in the refrigeration equipment is 6°C, and the OFF parameter is 5°C. When the ambient temperature is between 17 - 23°C (i.e., 17°C ≤ ambient temperature ≤ 23°C), the ON parameter of the refrigeration device in the refrigeration equipment is 6.5°C, and the OFF parameter is 5.5°C. On the premise that the range of the refrigeration equipment is at the second gear, the expected temperature (corresponding temperature) in the refrigeration equipment compartment is 3°C. When the ambient temperature is between 11 - 17°C (i.e., 11°C ≤ ambient temperature < 17°C), the ON parameter of the refrigeration device in the refrigeration equipment is 7°C, and the OFF parameter is 6°C. When the ambient temperature is between 17 - 23°C (i.e., 17°C ≤ ambient temperature ≤ 23°C), the ON parameter of the refrigeration device in the refrigeration equipment is 7.5°C, and the OFF parameter is 6.5°C. Among them, both the ON parameter and the OFF parameter are the temperatures detected by the temperature sensor. It can be understood that the temperature detected by the temperature sensor in the refrigeration equipment does not correspond to the actual temperature in the compartment, and there is a difference between the two. Therefore, there is a difference between the ON and OFF parameters and the corresponding temperature under the same gear.

[0042] However, as Figure 1 shown in the schematic diagram of the temperature sensor setting position in the refrigeration equipment, the temperature sensor in the refrigeration equipment is generally set on the side wall inside the refrigeration equipment compartment (i.e., Figure 1 the position marked by the black frame in Figure 2 ). As shown in the schematic diagram of the refrigeration device outlet setting position in the refrigeration equipment, the refrigeration device outlet in the refrigeration equipment is generally set in a certain layer inside the refrigeration equipment compartment (i.e., Figure 2 the position marked by the black frame in ). In summary, the setting positions of the temperature sensor and the refrigeration device outlet inside the refrigeration equipment compartment are independent of each other, and the temperature sensor mainly detects the local temperature and cannot detect the overall temperature inside the compartment. Moreover, the refrigeration device also starts to cool from the local area and cannot achieve synchronous cooling inside the compartment. Based on the above setting positions of the temperature sensor and the cooler opening in the refrigeration device, when a large amount of food is stored in the refrigeration equipment compartment, the space temperature sensor in the refrigeration equipment compartment can only sense the local temperature, and the refrigeration device starts to cool from the opening part, resulting in a temperature difference between different spatial positions inside the compartment. When the temperature at the position of the temperature sensor inside the refrigeration equipment compartment is relatively high and higher than the ON parameter of the refrigeration device, the refrigeration device will keep running, causing the temperature at other lower-temperature positions inside the compartment (such as near the refrigeration device outlet) to be too low and remain in a state of too low temperature continuously, resulting in the freezing of the refrigerated items at the corresponding positions and affecting the user experience.

[0043] In one example, the temperature in the refrigeration equipment compartment is adjusted by using the refrigeration method based on the startup parameters and shutdown parameters in the above related technology. As Figure 3 shown in the schematic diagram of the temperature change curve in the refrigeration equipment compartment during temperature control, Curve 1 is the temperature detected by the temperature sensor, and Curve 2 is the actual temperature in the compartment. Among them, before stage A, temperature control is performed based on the startup parameters and shutdown parameters to maintain the temperature in the compartment within a certain range. The process from stage A to B represents the process of the temperature in the compartment rising after putting the items to be refrigerated (such as dishes) into the compartment. From stage B to C, the refrigeration device of the refrigeration equipment is enabled to cool down, so that the temperature detected by the temperature sensor is reduced to the preset temperature node. After stage C, the temperature in the compartment reaches a certain temperature range, and temperature control is performed based on the startup parameters and shutdown parameters to maintain the temperature in the compartment. As Figure 3 shown, in the process from stage B to C, the temperature detected by the temperature sensor is always higher than the startup parameter, resulting in the continuous operation of the refrigeration device, and the actual temperature in the compartment continues to drop. As a result, during the cooling process, the temperature of some positions in the actual compartment will be lower than 0°C for a long time, which will have an adverse impact on the items to be refrigerated in the corresponding area of the compartment (such as being frozen).

[0044] In view of this, the present disclosure proposes a device control method. After putting the items to be refrigerated into the refrigeration equipment, when reducing the temperature in the refrigeration equipment compartment, a cooling means of alternately executing cooling on and off is adopted to make the temperature in the refrigeration equipment compartment reach the normal refrigeration temperature level. By turning off the cooling after cooling for a period of time, the overall temperature in the compartment is synchronously reduced, avoiding the situation that the local temperature where the temperature sensor in the compartment is located is higher than that of other parts and continuously cooling, resulting in the temperature of some parts in the compartment being at a relatively low level for a long time, and preventing adverse effects on the items to be refrigerated. While ensuring the refrigeration effect of the refrigeration equipment, the items to be refrigerated will not be frozen.

[0045] Figure 4 is a flowchart of a device control method shown according to an exemplary embodiment. As Figure 4 shown, the method includes steps S101 to S102.

[0046] In step S101, determine the currently detected temperature detected by the temperature sensor in the refrigeration equipment compartment, and determine the first temperature threshold corresponding to the current gear of the refrigeration equipment.

[0047] Among them, the first temperature threshold is the upper limit of the detected temperature range corresponding to the current gear of the refrigeration equipment, and different gears of the refrigeration equipment correspond to different detected temperature ranges.

[0048] In step S102, in response to the difference between the currently detected temperature and the first temperature threshold being greater than the difference threshold, the refrigeration device is controlled to cool the inside of the warehouse in the first temperature control mode.

[0049] Wherein, in the first temperature control mode, the refrigeration device alternately executes cooling on and cooling off according to different maintenance durations, and cooling on and cooling off respectively correspond to different maintenance durations.

[0050] In the embodiments of the present disclosure, the refrigeration device is pre-configured with multiple gears, and each gear corresponds to a preset temperature range detected by a temperature sensor. For example, gear 1 corresponds to 5-6 degrees Celsius, gear 2 corresponds to 6-7 degrees Celsius, gear 3 corresponds to 7-8 degrees Celsius... The first temperature threshold in the present disclosure is the upper limit of the temperature range detected by the temperature sensor corresponding to the current gear. For example, the first temperature threshold in gear 1 is 6 degrees Celsius.

[0051] In the embodiments of the present disclosure, a temperature control strategy for maintaining the refrigeration temperature is preset in the refrigeration device. When the items in the refrigeration device remain unchanged, the temperature inside the warehouse of the refrigeration device will not exceed the detected temperature range corresponding to the current gear. When the difference between the temperature inside the warehouse and the first temperature threshold is greater than the difference threshold, it indicates that new items to be refrigerated have been placed in the warehouse of the refrigeration device. In this case, it is necessary to cool down through a preset temperature control method to reduce the temperature detected by the temperature sensor to the preset temperature range.

[0052] In the embodiments of the present disclosure, when adjusting the temperature inside the warehouse of the refrigeration device, the temperature control method of alternately executing cooling on and cooling off according to different maintenance durations is used to achieve temperature adjustment, that is, the cooling function is turned on for a period of time and then turned off for a period of time, and this is repeated, so that the temperature inside the warehouse of the refrigeration device shows a downward trend as a whole. It can be understood that the opening of the refrigeration device in the refrigeration equipment is generally set at a certain position inside the warehouse. Due to the characteristic that the cooling temperature requires medium transfer, the temperature at the opening of the refrigeration device drops faster during temperature adjustment, and will be lower than the temperature of other positions inside the warehouse for a long time. The present disclosure makes the temperature inside the warehouse of the refrigeration device conduct through the period of turning on the cooling for a period of time and then turning off the cooling, and avoids the temperature at the opening of the refrigeration device being in a low temperature state for a long time, resulting in the items to be refrigerated near the opening of the refrigeration device being frozen.

[0053] In the embodiments of the present disclosure, after placing items to be refrigerated in the refrigeration device, the temperature control method of alternately executing cooling on and cooling off is used to reduce the temperature inside the warehouse of the refrigeration device to the refrigeration temperature. By turning off the cooling after cooling for a period of time, the overall temperature inside the warehouse is synchronously reduced, making the temperature inside the warehouse of the refrigeration device conduct, and avoiding the temperature at the opening of the refrigeration device being in a low temperature state for a long time, resulting in the items to be refrigerated near the opening of the refrigeration device being frozen, and avoiding user complaints.

[0054] It can be understood that the current gear of the refrigeration device of the present disclosure corresponds to a preset detection temperature range. Therefore, when cooling is performed by alternately executing the temperature control means of turning on and off the cooling in the above cycle, and the refrigerated temperature in the chamber reaches the preset refrigerated temperature, that is, when the temperature detected by the temperature sensor is within the preset detection temperature range, the temperature control strategy needs to be adaptively adjusted. An embodiment of the present disclosure describes a method for cooling the chamber using the first temperature control mode.

[0055] Figure 5 It is a flowchart of a method for controlling a refrigeration device to cool the chamber using the first temperature control mode shown according to an exemplary embodiment. As Figure 5 shown, the method includes steps S201 to S202.

[0056] In step S201, determine the second temperature threshold corresponding to the current gear of the refrigeration device, and determine the current detected temperature of the refrigeration device in real time.

[0057] Wherein, the second temperature threshold is the lower limit of the detection temperature range corresponding to the refrigeration device in the current gear.

[0058] In step S202, control the execution of the first temperature control mode according to the second temperature threshold and the current detected temperature.

[0059] In the embodiment of the present disclosure, the refrigeration device will be pre-configured with multiple gears, and each gear corresponds to a preset detection temperature range of the temperature sensor. For example: gear 1 corresponds to 5-6 degrees Celsius, gear 2 corresponds to 6-7 degrees Celsius, gear 3 corresponds to 7-8 degrees Celsius... The second temperature threshold in the present disclosure is the lower limit of the detection temperature range corresponding to the current gear. For example, the first temperature threshold in gear 1 is 5 degrees Celsius.

[0060] In the embodiment of the present disclosure, the purpose of cooling through the above first temperature control mode is to make the refrigerated temperature in the chamber reach the preset refrigerated temperature, that is, the temperature detected by the temperature sensor is within the preset detection temperature range. Therefore, while using the first temperature control mode for cooling, the present disclosure determines the lower limit of the detection temperature corresponding to the current gear of the refrigeration device, that is, the second temperature threshold, and obtains the current detected temperature detected by the temperature sensor in the chamber of the refrigeration device in real time. When the current detected temperature is the same as the second temperature threshold, it indicates that the cooling adjustment in the chamber has been completed, and the temperature control strategy can be further adjusted to keep the refrigerated temperature in the chamber of the refrigeration device within a certain range, that is, to keep the detected temperature detected by the temperature sensor within the preset detection temperature range.

[0061] In the embodiments of the present disclosure, the purpose of using the first temperature control mode for cooling is to make the temperature in the chamber reach the normal refrigeration temperature. Therefore, when using the first temperature control mode to adjust the temperature in the refrigeration equipment chamber and the detected temperature detected by the temperature sensor reaches the lower limit of the preset detection temperature range corresponding to the current gear, the cooling needs to be stopped and the refrigeration temperature needs to be maintained. The following embodiments of the present disclosure further illustrate the method of using the first temperature control mode for cooling.

[0062] Figure 6 It is a flowchart of a method for controlling the execution of the first temperature control mode according to a second temperature threshold and a current detected temperature shown in an exemplary embodiment. As Figure 6 shown, the method includes step S301, step S302A, and step S302B.

[0063] In step S301, control the refrigeration equipment to use the first temperature control mode to cool the chamber.

[0064] In step S302A, in response to the current detected temperature being greater than the second temperature threshold, maintain the first temperature control mode to cool the chamber.

[0065] In step S302B, in response to the current detected temperature being less than the second temperature threshold, turn off the first temperature control mode.

[0066] In the embodiments of the present disclosure, when the current detected temperature obtained by the temperature sensor reaches the lower limit of the preset detection temperature range, that is, the second temperature threshold, it indicates that the cooling of the newly added items to be refrigerated in the chamber is completed, the refrigeration temperature in the chamber tends to be stable, and there is no longer a need for continuous cooling. Therefore, turn off the first temperature control mode, stop cooling, and use other temperature control strategies to maintain the temperature in the chamber, ensuring that the refrigerated items are not frozen during the refrigeration process while ensuring normal refrigeration effects.

[0067] In the embodiments of the present disclosure, the opening and closing of the cooling are alternately executed in a cycle, and each corresponds to a different maintenance duration. The following embodiments of the present disclosure further illustrate the method of alternately executing the opening and closing of the cooling in the above cycle.

[0068] Figure 7 It is a flowchart of a method for alternately executing the opening and closing of the cooling in a cycle according to different maintenance durations shown in an exemplary embodiment. As Figure 7 shown, the method includes steps S401 to S402.

[0069] In step S401, after the cooling is turned on and maintained for the first duration, turn off the cooling and maintain it for the second duration.

[0070] In step S402, alternately execute the opening and closing of the cooling in a cycle.

[0071] In the embodiments of the present disclosure, the cooling duration and the off-cooling duration are respectively set, that is, the on-duration and the off-duration of the refrigeration device are respectively set. It can be understood that the settings of the on-duration and the off-duration of the refrigeration device will affect the cooling rate during the cooling process. The longer the on-duration of the refrigeration device, the faster the cooling rate, and vice versa. When setting the on-duration of the refrigeration device, it is necessary to consider the low-temperature maintenance duration near the opening of the refrigeration device during the cooling process to prevent the problem of freezing the refrigerated items. The off-duration of the refrigeration device needs to consider the temperature diffusion in the warehouse so that the overall temperature in the warehouse tends to be synchronized during the off-duration. In summary, the present disclosure needs to obtain the optimal on-duration and off-duration (i.e., the first duration and the second duration) of the refrigeration device based on experiments, so as to achieve the fastest cooling on the premise of ensuring that the overall temperature in the warehouse tends to be synchronized during the off-duration and preventing the problem of freezing the refrigerated items.

[0072] It can be understood that there are differences in the device parameters of different refrigeration devices, and there are also differences in the settings of the openings of the refrigeration devices and the temperature sensors. Therefore, when the device control method in the present disclosure is applied to different refrigeration devices, different first durations and second durations will be set.

[0073] It can be understood that the in-warehouse cooling process of the refrigeration device will be affected by the ambient temperature of its location. Therefore, when setting the first duration and the second duration in the present disclosure, the external ambient temperature needs to be considered. The following embodiments of the present disclosure will illustrate the method for determining the first duration and the second duration.

[0074] Figure 8 is a flowchart of a method for determining the first duration and the second duration shown according to an exemplary embodiment. As Figure 8 shown, the method includes steps S501 to step S502.

[0075] In step S501, the current ambient temperature is determined.

[0076] In step S502, the first duration is determined according to the correspondence between the current ambient temperature and the first duration, and the second duration is determined according to the correspondence between the current ambient temperature and the second duration.

[0077] In the embodiments of the present disclosure, the in - chamber temperature - reduction process of the refrigeration device is affected by the ambient temperature. The higher the external temperature, the lower the refrigeration rate. And when the refrigeration device of the refrigeration equipment is turned off, the higher the external temperature, the higher the rate of increase of the in - chamber temperature. Therefore, in the present disclosure, there is a corresponding relationship between the first duration and the second duration and the ambient temperature. The first duration is positively correlated with the ambient temperature, and the second duration is negatively correlated with the ambient temperature. The present disclosure can respectively set the corresponding first duration and second duration for different ambient temperature ranges, that is, determine the corresponding relationship between the ambient temperature and the first duration, and determine the corresponding relationship between the ambient temperature and the second duration. The present disclosure sets the first duration and the second duration according to the ambient temperature, that is, sets the on - time and off - time of the refrigeration device in the refrigeration equipment according to the ambient temperature, so as to achieve the fastest temperature reduction on the premise of ensuring that the overall temperature in the chamber tends to be synchronized during the off - time and preventing the problem of freezing the refrigerated items during the in - chamber temperature - reduction process of the refrigeration equipment.

[0078] In the embodiments of the present disclosure, after the in - chamber temperature reduction is completed through the first temperature - control mode, general temperature - control means can be used for temperature control to maintain the refrigerated temperature in the chamber, that is, temperature control is performed according to the start - up parameter (the first temperature threshold) and the shutdown parameter (the second temperature threshold) of the refrigeration device in the refrigeration equipment in combination with the currently detected temperature. It can be understood that when the newly added items to be refrigerated in the chamber have been cooled down and the refrigerated temperature in the chamber tends to be stable, the phenomenon that the temperature near the opening of the refrigeration device is too low for a long time will not occur, so the items to be refrigerated will not be frozen. In summary, the present disclosure stops the temperature reduction when the currently detected temperature obtained by the temperature sensor reaches the lower limit of the preset detection temperature range, and enables the second temperature - control mode to maintain the temperature, ensuring normal refrigeration effects while preventing the refrigerated items from being frozen during the refrigeration process. The following embodiments of the present disclosure illustrate the method for maintaining the in - chamber temperature of the refrigeration equipment based on the second temperature - control mode.

[0079] Figure 9 It is a flowchart of a device control method shown according to another exemplary embodiment. As Figure 9 shown, the method includes step S601, step S602A, and step S602B.

[0080] In step S601, in response to the completion of the in - chamber temperature reduction, the first temperature - control mode is turned off, and the second temperature - control mode is enabled to maintain the in - chamber temperature.

[0081] In step S602A, in response to the currently detected temperature being greater than the first temperature threshold, the temperature reduction is started.

[0082] In step S602B, in response to the currently detected temperature being less than the second temperature threshold, the temperature reduction is turned off.

[0083] In the embodiments of the present disclosure, when the items to be refrigerated newly added to the warehouse have completed temperature reduction and the refrigeration temperature in the warehouse tends to be stable, temperature control is performed according to the startup parameter (the first temperature threshold) and the shutdown parameter (the second temperature threshold) of the refrigeration device in the refrigeration equipment in combination with the currently detected temperature. When the currently detected temperature is greater than the first temperature threshold, that is, the currently detected temperature is greater than the upper limit of the preset detection temperature range, it indicates that the actual refrigeration temperature in the current warehouse is higher than the expected refrigeration temperature. Therefore, cooling is started to reduce the actual refrigeration temperature in the current warehouse to the expected refrigeration temperature. When the currently detected temperature is lower than the second temperature threshold, that is, the currently detected temperature is less than the lower limit of the preset detection temperature range, it indicates that the actual refrigeration temperature in the current warehouse is lower than the expected refrigeration temperature. Therefore, cooling is turned off to raise the actual refrigeration temperature in the current warehouse to the expected refrigeration temperature. Through the above temperature control method, the present disclosure makes the actual temperature in the refrigeration equipment warehouse approximately equal to the expected refrigeration temperature, ensuring the refrigeration effect of the refrigeration equipment.

[0084] In an exemplary embodiment of the present disclosure, the equipment control method in the present disclosure is used to adjust the temperature in the refrigeration equipment warehouse. As Figure 10 shown in the schematic diagram of the temperature change curve in the refrigeration equipment warehouse during temperature control, curve 1 is the temperature detected by the temperature sensor, and curve 2 is the actual temperature in the warehouse. Among them, before stage A, temperature control is performed based on the startup parameter and the shutdown parameter to maintain the temperature in the warehouse within a certain range. The process from stage A to B represents the process of the temperature in the warehouse rising after placing the items to be refrigerated (such as dishes) in the warehouse. The process from stage B to C is to use the equipment control method in the present disclosure to repeatedly execute starting the refrigeration device of the refrigeration equipment and closing the refrigeration device of the refrigeration equipment that has been started to cool the warehouse, so that the temperature detected by the temperature sensor is reduced to the preset temperature node, that is, the process of making the refrigeration temperature in the warehouse reach the expected refrigeration temperature. After stage C, when the temperature in the warehouse reaches a certain temperature range, temperature control is performed based on the startup parameter and the shutdown parameter to maintain the temperature in the warehouse. By comparing Figure 10 and Figure 3 it can be seen that in the process from stage B to C, the present disclosure reduces the duration of the low-temperature area in the warehouse (the area with a relatively lower temperature than other areas, such as near the opening of the refrigeration device) being lower than 0°C by repeatedly executing starting cooling and turning off cooling, which is less than Figure 3 the duration of being lower than 0°C in

[0085] In the embodiments of the present disclosure, the detected temperature detected by the temperature sensor of the refrigeration equipment is determined, and the upper limit of the detected temperature range at the current gear of the refrigeration equipment is determined. When the difference between the detected temperature and the first temperature threshold is greater than the difference threshold, a temperature control mode of alternately executing cooling start and cooling stop is used to cool the inside of the chamber. When alternately executing cooling start and cooling stop in a cycle, the first duration of cooling start is determined based on the ambient temperature, and the first duration of cooling stop is determined, and then cooling start and cooling stop are alternately executed in a cycle to reduce the refrigeration temperature inside the chamber. When the refrigeration temperature inside the chamber reaches the desired refrigeration temperature, that is, when the current temperature detected by the temperature sensor reaches the lower limit of the detected temperature range corresponding to the current gear, the cooling process ends, and the temperature inside the chamber is adjusted according to the detected temperature range corresponding to the current gear and the temperature detected by the temperature sensor, so that the temperature detected by the sensor is maintained within the detected temperature range corresponding to the current gear. Through the present disclosure, after placing the items to be refrigerated in the refrigeration equipment, a temperature control method of alternately executing cooling start and cooling stop in a cycle is adopted to reduce the detected temperature of the refrigeration equipment to the refrigeration temperature. By closing the cooling after cooling for a period of time, the overall temperature inside the chamber is synchronously reduced, avoiding the temperature at the opening of the refrigeration device being in a low temperature state for a long time, resulting in the items to be refrigerated near the opening of the refrigeration device being frozen, and avoiding user complaints.

[0086] Based on the same concept, the embodiments of the present disclosure further provide a device control device 100.

The second temperature threshold is the lower limit of the detected temperature range corresponding to the current gear of the refrigeration device. Control the execution of the first temperature control mode according to the second temperature threshold and the current detected temperature.

[0094] In one implementation, the processing unit 102 controls the execution of the first temperature control mode according to the second temperature threshold and the current detected temperature in the following manner: in response to the current detected temperature being greater than the second temperature threshold, maintain the first temperature control mode for in - chamber cooling.

[0095] In one implementation, the processing unit 102 alternately executes on - cooling and off - cooling in a cycle according to different maintenance durations in the following manner: after on - cooling is maintained for the first duration, off - cooling is maintained for the second duration.

[0096] In one implementation, the first duration and the second duration have a corresponding relationship with the ambient temperature. The first duration is positively correlated with the ambient temperature, and the second duration is negatively correlated with the ambient temperature. The first duration and the second duration are determined by the processing unit 102 in the following manner: determine the current ambient temperature, determine the first duration according to the corresponding relationship between the current ambient temperature and the first duration, and determine the second duration according to the corresponding relationship between the current ambient temperature and the second duration.

[0097] In one implementation, the processing unit 102 is further configured to: in response to the completion of in - chamber cooling, turn off the first temperature control mode and enable the second temperature control mode to maintain the in - chamber temperature. In the second temperature control mode, maintain the in - chamber temperature in the following manner: in response to the current detected temperature being greater than the first temperature threshold, turn on the cooling. In response to the current detected temperature being less than the second temperature threshold, turn off the cooling.
