Description

Technical Field

[0001] This application belongs to the field of refrigeration equipment technology, and particularly relates to a control method, device, and refrigeration equipment for refrigeration equipment. Background Technology

[0002] During the operation of refrigeration equipment, prolonged maintenance of low temperatures can cause frost or even ice to form on internal components such as the evaporator. Frost or ice buildup reduces the heat exchange efficiency of the refrigeration equipment, leading to a decrease in overall energy efficiency. Failure to remove frost or ice promptly can also damage the internal structure of the equipment. Therefore, it is essential to perform defrosting checks on refrigeration equipment and take timely defrosting measures.

[0003] Currently, refrigeration equipment typically uses timed defrosting, which may result in untimely or excessive defrosting. Summary of the Invention

[0048] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0049] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0050] It should be noted that the refrigeration equipment 200 in this embodiment can be understood as a refrigeration storage device in a broad sense, including but not limited to refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines. The refrigeration equipment 200 has various structural forms and a wide range of applications.

[0051] In this embodiment, the refrigeration device 200 can be a vending machine. The temperature of the storage compartment 210 of the vending machine can be below 0 degrees Celsius. In some embodiments, the temperature of the storage compartment 210 of the vending machine can be from -5°C to -30°C, such as -25°C. The vending machine is used to sell frozen goods, such as ice cream and ice cubes.

[0052] The control method, control device, refrigeration equipment 200, electronic equipment, and readable storage medium of the refrigeration equipment 200 provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0053] The control method for the refrigeration equipment 200 can be applied to the terminal, and can be executed by the hardware or software in the terminal.

[0054] The terminal includes, but is not limited to, a desktop computer. The following embodiments describe a terminal including a display and a touch-sensitive surface. However, it should be understood that the terminal may include one or more other physical user interface devices such as a physical keyboard, mouse, and joystick.

[0055] The control method for the refrigeration device 200 provided in this application embodiment can be executed by an electronic device or a functional module or functional entity in an electronic device that can implement the control method for the refrigeration device 200. The electronic devices mentioned in this application embodiment include, but are not limited to, mobile phones, tablet computers, computers, cameras and wearable devices. The control method for the refrigeration device 200 provided in this application embodiment will be described below using an electronic device as the execution subject.

[0056] like Figure 2 As shown, the refrigeration device 200 of this application embodiment includes a compressor (not shown in the figure), an evaporator 220, etc., wherein the compressor drives the refrigeration cycle by compressing the refrigerant, and the evaporator 220 achieves refrigeration by absorbing heat through the evaporation of the refrigerant.

[0057] like Figure 2 As shown, the refrigeration device 200 of this application embodiment has a storage compartment 210, which is a space for storing food and other items that can be refrigerated or frozen.

[0058] like Figure 3 As shown, the storage room 210 may have an opening, which is used by users to access items stored in the storage room 210. The opening of the storage room 210 may be equipped with a door 310, which can be used to open or close the opening of the storage room 210.

[0059] It is understandable that when the door 310 is closed, the storage room 210 is a sealed space that can isolate the refrigeration equipment 200 from the external environment.

[0060] like Figure 4 As shown, the cold air generated by the evaporator 220 is driven by the fan 230 to flow to the storage compartment 210, providing cooling capacity to the storage compartment 210. After passing through the storage compartment 210, the cold air blows towards the evaporator 220, forming an air circulation. When the humid air comes into contact with the cool surface of the evaporator 220, the water vapor in the air may condense into water droplets or even freeze to form frost.

[0061] The control method of the refrigeration equipment 200 in this application embodiment is used to determine whether the equipment such as the evaporator 220 in the refrigeration equipment 200 is to defrost, and to perform the defrosting action when it is determined to defrost.

[0062] like Figure 1 As shown, the control method of the refrigeration equipment 200 includes steps 110 and 120.

[0063] Step 110: Obtain at least two of the following: first temperature data, second temperature data, compressor running time, and cumulative number of times the storage compartment 210 is opened when the refrigeration equipment 200 is in an undefrosted state.

[0064] The first temperature data is the temperature data of the location of the evaporator 220 of the refrigeration equipment 200, and the second temperature data is the temperature data of the storage room 210.

[0065] In this embodiment, the refrigeration device 200 being in an undefrosted state means that the refrigeration device 200 has not performed a defrosting action and is in a normal refrigeration state.

[0066] In this embodiment, after each defrosting action of the refrigeration equipment 200, the first temperature data, the second temperature data, the compressor running time, and the cumulative number of times the storage compartment 210 is opened can be obtained in real time to perform defrosting judgment. That is, after each defrosting action of the refrigeration equipment 200, there is a defrosting judgment period. The defrosting judgment period can be the time period between the end time of the most recent defrosting action of the refrigeration equipment 200 and the current time.

[0067] In this step, a first temperature sensor can be installed at the location of the evaporator 220. The first temperature sensor is used to acquire first temperature data in real time. The first temperature sensor can be installed at the input end of the evaporator 220.

[0068] A second temperature sensor can be installed in the storage room 210 to acquire second temperature data in real time.

[0069] It is understandable that the compressor can start and stop multiple times during the defrosting judgment period, meaning that the compressor can be in operation for multiple discontinuous periods.

[0070] In this embodiment, the compressor running time is the duration during which the compressor is in operation during the defrosting judgment period, that is, the sum of the durations corresponding to multiple periods during which the compressor is in operation during the defrosting judgment period.

[0071] For example, if the compressor is in operation for three discontinuous periods during the defrosting period, with durations of 0.5h, 0.4h, and 0.5h respectively, then the compressor's operating time is 0.5h + 0.4h + 0.5h = 1.4h.

[0072] In this step, the compressor can be connected to a timer, which is used to keep track of the compressor's running time while it is in operation.

[0073] In this embodiment, the storage room 210 can be in an open or closed state. When the door 310 of the storage room 210 is open, the storage room 210 is in an open state; when the door 310 of the storage room 210 is closed, the storage room 210 is in a closed state.

[0074] It is understandable that the door 310 of the storage room 210 can be opened and closed multiple times during the defrosting judgment period. The cumulative number of times the door of the storage room 210 is opened is the number of times the door 310 of the storage room 210 is opened during the defrosting judgment period.

[0075] In this step, a Hall switch can be installed on the door 310 of the storage room 210, and a magnetic material can be installed on the door frame corresponding to the door 310 of the storage room 210. When the door 310 is opened, the magnetic material moves away from the Hall switch, and the corresponding magnetic field sensor detects the change in magnetic field between the Hall switch and the magnetic material and outputs the corresponding electrical signal.

[0076] The cumulative number of times the storage room 210 has been opened can be obtained by monitoring the electrical signals corresponding to changes in the magnetic field.

[0077] In this step, two, three, or all of the following data can be obtained: first temperature data, second temperature data, compressor running time, and cumulative number of times the storage compartment 210 is opened, for use in defrosting determination.

[0078] Step 120: If, based on at least two of the first temperature data, the second temperature data, the compressor running time, and the cumulative number of door openings, the triggering conditions are met, control the refrigeration equipment 200 to perform a defrosting action.

[0079] The triggering condition is the condition that triggers the refrigeration equipment 200 to perform the defrosting action.

[0080] In this embodiment, the trigger condition can be determined to be met when at least two of the following conditions are met: the first temperature data meets the corresponding first temperature condition, the second temperature data meets the corresponding second temperature condition, the compressor running time meets the corresponding running time condition, and the cumulative number of door openings meets the corresponding number of door openings condition.

[0081] In this step, if the triggering conditions are met, the refrigeration equipment 200 is controlled to perform a defrosting action.

[0082] In this embodiment, such as Figure 4 As shown, the evaporator 220 of the refrigeration equipment 200 can be equipped with heating devices such as heating tubes 240, and the heating tubes 240 can be controlled to heat the evaporator 220, thereby realizing defrosting. The heating tubes 240 can be defrosting heating steel tubes or defrosting heating aluminum tubes.

[0083] In this embodiment, an electric valve can also be installed at the discharge end of the compressor. When the refrigeration equipment 200 performs the defrosting action, the electric valve is controlled to open, and the hot gas discharged from the compressor passes through the evaporator 220 to defrost the evaporator 220.

[0084] In related technologies, refrigeration equipment 200 is usually defrosted on a timed basis. Timed defrosting may result in untimely or excessive defrosting.

[0085] According to the control method of the refrigeration equipment 200 provided in the embodiments of this application, when the refrigeration equipment 200 is in an undefrosted state, it is determined whether the defrosting trigger condition is met based on the temperature data of the location of the evaporator 220, the temperature data of the storage compartment 210, the compressor running time, and the cumulative number of times the storage compartment 210 is opened. If the trigger condition is met, the refrigeration equipment 200 is controlled to perform the defrosting action, which can ensure that the refrigeration equipment 200 defrosts in a timely manner when there is a defrosting need, thereby improving the refrigeration efficiency.

[0086] In some embodiments, if at least two of the following are determined to be met based on first temperature data, second temperature data, compressor runtime, and cumulative door opening counts, the refrigeration equipment 200 is controlled to perform a defrosting action, including:

[0087] Based on the first temperature data, the second temperature data, and the compressor operating time, if the first triggering condition is met, the refrigeration equipment 200 is controlled to perform a defrosting action.

[0088] In this embodiment, defrosting is determined based on the first temperature data, the second temperature data, and the compressor running time. When the first temperature data meets the corresponding first temperature condition, the second temperature data meets the corresponding second temperature condition, and the compressor running time meets the corresponding running time condition, it can be determined that the first trigger condition is met.

[0089] The first triggering condition is the condition that triggers the refrigeration equipment 200 to perform the defrosting action. When the first triggering condition is met, the refrigeration equipment 200 is controlled to perform the defrosting action.

[0090] In some embodiments, determining whether a first triggering condition is met based on first temperature data, second temperature data, and compressor runtime includes:

[0091] The first triggering condition is determined to be met when the compressor running time exceeds the first target duration, the first temperature data is less than the first temperature threshold and the duration exceeds the second target duration, the second temperature data is greater than the second temperature threshold and the duration exceeds the third target duration, and the second temperature data shows an increasing trend.

[0092] It is understandable that the compressor running time is greater than the first target time, which means the compressor running time meets the corresponding running time condition; the first temperature data is less than the first temperature threshold and its duration is greater than the second target time, which means the first temperature data meets the corresponding first temperature condition; the second temperature data is greater than the second temperature threshold and its duration is greater than the third target time, and the second temperature data shows an increasing trend, which means the second temperature data meets the corresponding second temperature condition.

[0093] Among them, the first target duration, the second target duration, and the third target duration are preset durations. The first target duration, the second target duration, and the third target duration can be the same or different. The first temperature threshold and the second temperature threshold are preset temperature values.

[0094] In this embodiment, a frosting test can be performed on the refrigeration equipment 200. In the frosting test, a first target duration is determined based on the relationship between the compressor's running time and the degree of frosting on the refrigeration equipment 200.

[0095] In the frosting test, the first temperature threshold and the second target duration are determined based on the relationship between the temperature data of the evaporator 220 location over a certain period of time and the degree of frosting of the refrigeration equipment 200.

[0096] In the frosting test, the second temperature threshold and the third target duration are determined based on the relationship between the temperature data of the storage room 210 over a certain period of time and the degree of frosting of the refrigeration equipment 200.

[0097] In this embodiment, when the compressor running time exceeds the first target time, the first temperature data is less than the first temperature threshold and the duration exceeds the second target time, the second temperature data is greater than the second temperature threshold and the duration exceeds the third target time, and the second temperature data shows an increasing trend, it indicates that the compressor has accumulated a long running time. The evaporator 220 is located at a low temperature due to excessive frost, and the temperature in the storage compartment 210 continues to rise and has reached a high temperature. At this time, the refrigeration equipment 200 has a defrosting requirement, and the refrigeration equipment 200 is controlled to perform a defrosting action.

[0098] In some embodiments, if at least two of the following are determined to be met based on first temperature data, second temperature data, compressor runtime, and cumulative door opening counts, the refrigeration equipment 200 is controlled to perform a defrosting action, including:

[0099] Based on the first temperature data and the cumulative number of door openings, if the second triggering condition is met, the refrigeration equipment 200 is controlled to perform a defrosting action.

[0100] In this embodiment, defrosting is determined based on the first temperature data and the cumulative number of door openings. When the first temperature data meets the corresponding third temperature condition and the cumulative number of door openings meets the corresponding number of door openings condition, it can be determined that the second trigger condition is met.

[0101] The second triggering condition is the condition that triggers the refrigeration equipment 200 to perform the defrosting action. When the second triggering condition is met, the refrigeration equipment 200 is controlled to perform the defrosting action.

[0102] In some embodiments, determining whether a second triggering condition is met based on first temperature data and cumulative door opening counts includes:

[0103] If the first temperature data is less than the third temperature threshold, the duration of the first temperature data is greater than the fourth target duration, and the cumulative number of door openings is greater than the threshold for the number of door openings, then the second triggering condition is determined to be met.

[0104] It is understandable that if the first temperature data is less than the third temperature threshold and the duration is greater than the fourth target duration, the first temperature data meets the corresponding third temperature condition, and the cumulative number of door openings is greater than the door opening count threshold, the cumulative number of door openings meets the corresponding door opening count condition.

[0105] Among them, the fourth target duration is a preset duration, the third temperature threshold is a preset temperature value, and the door opening number threshold is a preset value.

[0106] In this embodiment, a frosting test can be performed on the refrigeration equipment 200. In the frosting test, a third temperature threshold and a fourth target duration are determined based on the relationship between the temperature data of the location of the evaporator 220 over a certain period of time and the degree of frosting of the refrigeration equipment 200.

[0107] In the frosting test, the threshold number of times the door of storage room 210 is determined based on the relationship between the number of times the door is opened and the degree of frosting on the refrigeration equipment 200.

[0108] In this embodiment, when the first temperature data is less than the third temperature threshold and the duration is greater than the fourth target duration, and the cumulative number of door openings is greater than the door opening threshold, it indicates that the temperature at the location of the evaporator 220 is low due to excessive frost, and the door 310 of the storage compartment 210 is opened multiple times, resulting in high humidity in the refrigeration cycle system. The evaporator 220 is more prone to frost formation, and the refrigeration equipment 200 has a defrosting requirement. The refrigeration equipment 200 is then controlled to perform a defrosting action.

[0109] In some embodiments, such as Figure 5 As shown, after the refrigeration equipment 200 performs the defrosting action, the method further includes steps 510 and 520.

[0110] Step 510: Obtain at least one of the third temperature data corresponding to the defrosting state of the refrigeration equipment 200 and the defrosting time of the refrigeration equipment 200.

[0111] The third temperature data is the temperature data of the location of the evaporator 220 of the refrigeration equipment 200.

[0112] It is understandable that the first temperature data is the temperature data of the evaporator 220 when the refrigeration equipment 200 is in the undefrosted state; the third temperature data is the temperature data of the evaporator 220 when the refrigeration equipment 200 is in the defrosting state.

[0113] In this embodiment, the state of the refrigeration device 200 in defrost mode is the state corresponding to when the refrigeration device 200 performs the defrost action.

[0114] In this embodiment, after the refrigeration device 200 enters the defrosting state, the third temperature data and the defrosting duration of the refrigeration device 200 can be obtained in real time to determine whether to stop defrosting. That is, each time the refrigeration device 200 performs a defrosting action, there is a corresponding defrosting stop determination period. The defrosting stop determination period can be the time period between the start time of the defrosting action of the refrigeration device 200 and the current time.

[0115] In this step, the third temperature data can be obtained in real time by a first temperature sensor set at the location of the evaporator 220. That is, the first temperature sensor can obtain the third temperature data when the refrigeration equipment 200 is in the defrosting state, and obtain the first temperature data when the refrigeration equipment 200 is in the undefrosting state.

[0116] In this step, a timer can be set to calculate the defrosting time of the refrigeration equipment 200, that is, the duration for which the refrigeration equipment 200 performs the defrosting action.

[0117] In this embodiment, one of the third temperature data and the defrosting time of the refrigeration device 200 can be obtained, or both the third temperature data and the defrosting time of the refrigeration device 200 can be obtained simultaneously, for use in determining whether to stop defrosting.

[0118] Step 520: If, based on at least one of the third temperature data and the defrosting time, the stopping condition is met, control the refrigeration equipment 200 to stop the defrosting operation.

[0119] The stopping condition is the condition under which the refrigeration equipment 200 stops defrosting.

[0120] In this embodiment, if at least one of the third temperature data satisfies the corresponding fourth temperature condition and the defrosting time satisfies the corresponding defrosting time condition, it can be determined that the stop condition is met. If the stop condition is met, the refrigeration equipment 200 is controlled to stop the defrosting operation.

[0121] In this embodiment, when the evaporator 220 of the refrigeration equipment 200 is defrosting by heating devices such as heating tubes 240, the heating tubes 240 can be controlled to stop heating the evaporator 220, thereby stopping defrosting.

[0122] In this embodiment, when the refrigeration equipment 200 defrosts using the hot gas discharged from the compressor, the electric valve at the discharge end of the compressor is closed to stop defrosting the evaporator 220.

[0123] In some embodiments, determining whether a stopping condition is met based on at least one of third temperature data and defrosting time includes:

[0124] If the third temperature data is greater than the fourth temperature threshold, the stopping condition is determined to be met.

[0125] The fourth temperature threshold is a preset temperature value that can be used to conduct a defrosting test on the refrigeration equipment 200. In the defrosting test, the fourth temperature threshold is determined based on the relationship between the temperature data at the location of the evaporator 220 and the degree of defrosting of the refrigeration equipment 200.

[0126] In this embodiment, when the third temperature data is greater than the fourth temperature threshold, it indicates that the temperature at the location of the evaporator 220 is high, causing the frost to melt. The refrigeration equipment 200 can then stop the defrosting process and continue normal refrigeration.

[0127] In some embodiments, determining whether a stopping condition is met based on at least one of third temperature data and defrosting time includes:

[0128] If the defrosting time exceeds the duration of the fifth target, the stopping condition is determined to be met.

[0129] The fifth target duration is a preset duration that can be used to conduct defrosting tests on the refrigeration equipment 200. In the defrosting test, the fifth target duration is determined based on the relationship between the test defrosting duration corresponding to the defrosting action performed by the refrigeration equipment 200 and the degree of defrosting of the refrigeration equipment 200.

[0130] In this embodiment, when the defrosting time is longer than the fifth target time, it indicates that the evaporator 220 has been defrosted for a relatively long time, the frost on the evaporator 220 has melted, and the refrigeration equipment 200 can stop the defrosting operation and continue normal refrigeration.

[0131] The following is a specific embodiment of a control method for a refrigeration device 200.

[0132] like Figure 6 As shown, in step one, the refrigeration equipment 200 is in normal temperature control, that is, when the refrigeration equipment 200 is in a defrost state, the first temperature data, the second temperature data, the compressor running time, and the cumulative number of times the storage compartment 210 is opened are acquired in real time.

[0133] Step 2: Determine if the cumulative number of door openings is greater than 20. If the cumulative number of door openings is greater than 20, determine if the first temperature data is less than -25℃ and lasts for more than 30 minutes. If the first temperature data is less than -25℃ and lasts for more than 30 minutes, the refrigeration equipment 200 will perform a defrosting action. Otherwise, continue to determine in real time whether the triggering conditions are met.

[0134] At the same time, it is determined whether the following conditions are met simultaneously: the compressor running time is greater than 2 hours, the second temperature data minus the set temperature is greater than 3°C and the duration is greater than 30 minutes, the second temperature data shows an increasing trend, and the first temperature data is less than -25°C and the duration is greater than 30 minutes. If all conditions are met simultaneously, the refrigeration equipment 200 performs the defrosting action; otherwise, it continues to determine in real time whether the triggering conditions are met.

[0135] The set temperature is a preset temperature value, which can be determined based on the temperature of the storage compartment 210 when the refrigeration equipment 200 is turned on.

[0136] Step 3: When the refrigeration equipment 200 is in defrosting mode, acquire the defrosting time and third temperature data in real time.

[0137] Step 4: Determine if the third temperature data is greater than 20℃. If the third temperature data is greater than 20℃, the refrigeration equipment 200 stops defrosting; otherwise, the refrigeration equipment 200 continues to perform defrosting.

[0138] At the same time, it is determined whether the defrosting time is greater than 20 minutes. If the defrosting time is greater than 20 minutes, the refrigeration equipment 200 stops the defrosting action; otherwise, the refrigeration equipment 200 continues to perform the defrosting action.

[0139] It should be noted that the cumulative number of door openings is used as a trigger condition. When the refrigeration equipment 200 performs the defrosting action, the cumulative number of door openings is reset to zero after the refrigeration equipment 200 stops defrosting.

[0140] The following describes a specific embodiment of a control method for another refrigeration device 200.

[0141] Step 1: Refrigeration equipment 200 is in normal temperature control mode. That is, when refrigeration equipment 200 is in a defrost state, the first temperature data, the second temperature data, the compressor running time, and the cumulative number of times the storage compartment 210 is opened are acquired in real time.

[0142] Step 2: Determine whether the cumulative number of door openings is greater than or equal to 20 times and the first temperature data is less than or equal to -25℃ and lasts for more than 30 minutes. If both conditions are met, the refrigeration equipment 200 will perform the defrosting action. Otherwise, continue to determine in real time whether the triggering conditions are met.

[0143] Meanwhile, the following conditions apply: Case 1 is that the compressor runs for 2 hours or more; Case 2 is that the second temperature data minus the set temperature is greater than 3°C; Case 3 is that the second temperature data shows a continuous or spirally increasing trend; Case 4 is that the first temperature data is less than or equal to -25°C; and Case 5 is that Cases 2, 3, and 4 are all met simultaneously and their duration is greater than or equal to 30 minutes. It is then determined whether Case 1 and Case 5 are met simultaneously. If they are met simultaneously, the refrigeration equipment 200 performs the defrosting action; otherwise, it continues to determine in real time whether the triggering conditions are met.

[0144] Step 3: When the refrigeration equipment 200 is in defrosting mode, acquire the defrosting time and third temperature data in real time.

[0145] Step 4: Determine if the third temperature data is greater than 20℃. If the third temperature data is greater than 20℃, the refrigeration equipment 200 stops defrosting; otherwise, the refrigeration equipment 200 continues to perform defrosting.

[0146] At the same time, it is determined whether the defrosting time is greater than 20 minutes. If the defrosting time is greater than 20 minutes, the refrigeration equipment 200 stops the defrosting action; otherwise, the refrigeration equipment 200 continues to perform the defrosting action.

[0147] It should be noted that the cumulative number of door openings is used as a trigger condition. When the refrigeration equipment 200 performs the defrosting action, the cumulative number of door openings is reset to zero after the refrigeration equipment 200 stops defrosting.
