Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment control, and in particular to a refrigerator start-stop parameter control method and a refrigerator. Background Art

[0002] With the development of technology and the improvement of people's living standards, refrigerators have become a necessity for every family. At present, most refrigerators are air-cooled refrigerators, which use fans to circulate air for cooling. In air-cooled refrigerators, the cooler lowers the temperature inside the refrigerator by blowing cold air from the fan. This cold air is evenly distributed to various parts of the refrigerator, thereby achieving overall cooling.

[0003] The compressor is the core component of refrigerator refrigeration. The important parameter for controlling the start and stop of the compressor is the start and stop temperature point, which is usually calculated by the refrigerator set temperature and the start and stop parameters through a fixed formula. The start and stop parameters are obtained in the laboratory through performance matching tests. The start and stop parameters of refrigerators of the same model, or even refrigerators of the same series with the same structural type, are generally the same. However, due to deviations in assembly of the production line and differences in the working conditions of users using the refrigerators, the refrigerator refrigeration effect of the same model or series of refrigerators varies greatly even under the same start and stop parameters. As a result, there will be phenomena such as poor refrigerator refrigeration effect, refrigerator failure to refrigerate, and too low refrigerated room temperature.

[0004] In response to the above abnormal problems, the common practice is for the manufacturer to arrange after-sales personnel to visit the refrigerator to adjust the start and stop parameters to solve them. However, the after-sales personnel visiting the refrigerator to adjust the start and stop parameters will increase the after-sales service costs on the one hand; on the other hand, since there are corresponding start and stop parameters for different compartments and different ambient temperatures, there are a large number of start and stop parameters, and the start and stop parameters are generally represented by special symbols composed of letters and numbers. When adjusting the start and stop parameters, the after-sales personnel will have the risk of adjusting the start and stop parameters incorrectly, and will not be able to adjust the start and stop parameters of the refrigerator compartment in time.

BRIEF DESCRIPTION OF THE DRAWINGS

[0045] In order to more clearly illustrate the technical solution of the present application, the drawings required for use in the embodiments are briefly introduced below. Obviously, for ordinary technicians in this field, other drawings can be obtained based on these drawings without any creative work.

[0046] Figure 1 A flow chart of a refrigerator start-stop parameter control method provided in an embodiment of the present application. DETAILED DESCRIPTION

[0047] The following embodiments are described in detail, and examples thereof are shown in the accompanying 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 implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.

[0048] The refrigerator provided in the embodiment of the present application is a refrigeration device, which at least includes a refrigeration system, a cooling system, a control system and a cabinet to achieve refrigeration and operation. Among them, the refrigeration system is used to produce a refrigeration effect, the cooling system is used to maintain a low temperature environment, the control system is used to control the temperature and humidity in the refrigerator, etc., and the cabinet is used to provide storage space. It can be understood that the refrigeration system, the cooling system, and the control system include specific components that can achieve the above functions.

[0049] In some embodiments, the refrigeration system includes a compressor, a condenser, an evaporator, and a throttling device. Among them, the compressor is used to compress the refrigerant gas, increase the pressure and temperature, and thus promote the flow of the refrigerant in the system. During the compression process, the refrigerant changes from a low-pressure and low-temperature gas to a high-pressure and high-temperature gas, thereby producing a refrigeration effect. The condenser is used to cool the high-temperature and high-pressure gas discharged from the compressor into a liquid state. The heat is released through the heat sink, and the refrigerant gas is converted into a liquid state, ready to enter the next step of the refrigeration cycle. The evaporator is used to absorb heat in the refrigeration system. The refrigerant evaporates from a liquid state to a gas state in the evaporator, absorbing heat from the surrounding environment, thereby achieving the purpose of lowering the temperature inside the refrigerator. The throttling device may include an expansion valve and a capillary tube, which are used to adjust the flow rate of the refrigerant, reduce its pressure, and make it become a low-temperature and low-pressure gas-liquid mixed state, ready to enter the evaporator.

[0050] In some embodiments, the cooling system includes a fan connected to the evaporator. The fan circulates air in the compartments, such as the freezer and refrigerator, to transfer heat to the evaporator, helping to maintain a low temperature environment inside the refrigerator.

[0051] It should be noted that the above example is merely a simple division of the functions of the refrigerator and does not constitute a limitation on the specific structure of the refrigerator in the embodiment of the present application.

[0052] Among them, the compressor is the core component of refrigerator refrigeration. The important parameter for controlling the start and stop of the compressor is the start and stop temperature point, which is usually calculated by the refrigerator set temperature and the start and stop parameters through a fixed formula. The start and stop parameters are obtained in the laboratory through performance matching tests. The start and stop parameters of refrigerators of the same model, or even refrigerators of the same series with the same structural type, are generally the same. However, due to deviations in assembly of the production line and differences in the working conditions of users using the refrigerators, the refrigerator refrigeration effect of the same model or series of refrigerators varies greatly even under the same start and stop parameters. Therefore, there will be phenomena such as poor refrigerator refrigeration effect, refrigerator failure to refrigerate, and too low refrigerated room temperature.

[0053] In response to the above abnormal problems, the common practice is for the manufacturer to arrange after-sales personnel to visit the refrigerator to adjust the start and stop parameters to solve them. However, the after-sales personnel visiting the refrigerator to adjust the start and stop parameters will increase the after-sales service costs on the one hand; on the other hand, since there are corresponding start and stop parameters for different compartments and different ambient temperatures, there are a large number of start and stop parameters, and the start and stop parameters are generally represented by special symbols composed of letters and numbers. When adjusting the start and stop parameters, the after-sales personnel will have the risk of adjusting the start and stop parameters incorrectly, and will not be able to adjust the start and stop parameters of the refrigerator compartment in time.

[0054] To solve the problem of low efficiency and even wrong adjustment caused by manual adjustment of the start and stop parameters of the refrigerator compartment, see Figure 1Some embodiments of the present application provide a method for controlling the start-stop parameters of a refrigerator, including:

[0055] S100: Obtain the start and stop parameters of each refrigerator compartment at preset intervals and send them to the server.

[0056] The start and stop parameters at least include the temperature of each compartment, the set temperature of each compartment, the damper status, the fan status, the electric valve status, the compressor status and the evaporator temperature of each compartment.

[0057] For example, the temperature of each compartment may include the temperature of the refrigerating room, the temperature of the freezing room, and the temperature of the variable temperature room; wherein the temperature of the refrigerating room may be obtained by a temperature sensor provided in the refrigerating room, the temperature of the freezing room may be obtained by a temperature sensor provided in the refrigerating room, and the temperature of the variable temperature room may be obtained by a temperature sensor provided in the variable temperature room; the damper state and the fan state both include an open state and a closed state; the electric valve state includes the direction in which the electric valve is connected to the refrigeration system, for example, when the refrigerating room is refrigerated, the direction in which the electric valve is connected to the refrigerating system is toward the refrigerating evaporator, and when the freezing room is refrigerated, the direction in which the electric valve is connected to the refrigerating system is toward the freezing evaporator. The temperature of the evaporator of each compartment may be obtained by an evaporation temperature sensor, for example, the refrigerating room is provided with a refrigerating evaporator corresponding to the refrigerating room, the freezing room is provided with a freezing evaporator corresponding to the freezing room, the refrigerating evaporator is provided with a temperature sensor, and the freezing evaporator is provided with a temperature sensor, and the temperatures of the refrigerating evaporator and the freezing evaporator may be obtained respectively.

[0058] Sending the start and stop parameters of each refrigerator compartment to the server specifically includes:

[0059] The controller obtains the start and stop parameters of each compartment of the refrigerator at preset intervals;

[0060] The control wireless device combines and packages the start and stop parameters according to the communication protocol format to form a data packet; and sends the data packet to the server.

[0061] The control server parses the data packet to obtain the startup and shutdown parameters.

[0062] For example, the controller reads and records the start and stop parameters of each refrigerator compartment every five minutes; then the controller transmits the collected start and stop parameters to the wireless device. The wireless device packages the start and stop parameters into a data packet according to a predetermined communication protocol, such as Wi-Fi, Bluetooth, Zigbee, etc. The data packet contains all the information that needs to be transmitted, and the format meets the requirements of the communication protocol to ensure that the data packet can be correctly parsed and processed.

[0063] The wireless device sends the packaged data packet to the server via a wireless network, such as a home Wi-Fi network. After receiving the data packet from the refrigerator wireless device, the server uses a corresponding communication protocol parsing tool to parse the received data packet.

[0064] During the parsing process, the server extracts the start-stop parameters in the data packet and performs further processing and analysis. For example, the start-stop parameters are classified and stored according to type. As shown in Table 1, Table 1 is a start-stop parameter storage table.

[0065] Table 1 Start-stop parameter storage table

[0066]

[0067] Among them, the start and stop parameters after parsing can be stored separately according to data types, and when needed, the required information can be directly extracted from the table.

[0068] S200: Compare the temperature of each compartment with the set temperature of each compartment to obtain a first comparison result;

[0069] Calculate the difference between the temperature of each compartment and the set temperature of each compartment in chronological order;

[0070] If the differences are all greater than the first preset threshold or the differences are all less than the second preset threshold, the preset condition is met.

[0071] It can be understood that when obtaining the start-stop parameters, each set of start-stop corresponds to a start-stop parameter collection time point. The difference between the temperature of each compartment and the set temperature of each compartment is calculated in chronological order. Taking Table 1 as an example, the difference between the temperature of each compartment and the set temperature of each compartment at 12:05 is first calculated, and then the difference between the temperature of each compartment and the set temperature of each compartment at 12:10 is calculated. For example, the first preset threshold is 4°C, the set temperature of the cold storage room is 5°C, the temperature of the cold storage room detected by the cold storage room temperature sensor at 12:10 is 10°C, and the difference is 5°C. The temperature of the cold storage room detected by the cold storage room temperature sensor at 12:15 is 11°C, and the difference is 6°C. The temperature of the cold storage room detected by the cold storage room temperature sensor at 12:20 is 10°C, and the difference is 5°C. After the calculation is completed in sequence, when all the differences are greater than the first preset threshold, the preset condition is met.

[0072] In addition, similarly, when the differences between the temperatures of each compartment and the set temperatures of each compartment calculated in chronological order are all less than the second preset threshold, the preset condition can also be met.

[0073] S300: If the first comparison result meets the preset condition, the number of times the compressor is started and stopped is obtained according to the compressor state;

[0074] Obtain the compressor status in chronological order; the compressor status includes the compressor on status and the compressor off status;

[0075] The number of times the compressor state changes from the compressor on state to the compressor off state is obtained; the number of times the compressor on state changes to the compressor off state is the compressor on-off number.

[0076] The compressor start and stop times are the number of times the compressor changes from the on state to the off state. As shown in Table 1, the compressor state is on at 12:15 and off at 12:20. The compressor is started and stopped once from 12:15 to 12:20, and the compressor start and stop times are increased by 1. In the embodiment of the present application, when it is necessary to obtain the compressor start and stop times within 48 hours, the compressor state data can be traversed in chronological order, and the number of times the compressor state changes from the on state to the off state can be obtained, so as to obtain the compressor start and stop times.

[0077] S400: If the number of compressor start and stop times is greater than a third preset threshold, a start and stop parameter adjustment instruction is generated according to the first comparison result, the damper state, the fan state, the electric valve state and the evaporator temperature of each compartment; the start and stop parameter adjustment instruction is used to control the start and stop parameters of the refrigerator compartment to increase or decrease.

[0078] Specifically, generating a start / stop parameter adjustment instruction according to the first comparison result, the damper state, the fan state, the electric valve state, and the evaporator temperature of each compartment includes:

[0079] If the first comparison result is that the difference is greater than the first preset threshold, and the electric valve state is that the damper state and the fan state of the compartment corresponding to the direction in which the electric valve connects to the refrigeration system are open, and the evaporator temperature value is on a downward trend, then the start-stop parameters are controlled to decrease.

[0080] The refrigerator controller uploads all the start and stop parameters of different ambient temperatures and different compartments to the wireless module at fixed intervals; the start and stop parameters include the temperature of each compartment detected by the temperature sensor of each compartment, the evaporator temperature detected by the evaporator temperature sensor of each compartment, the set temperature of each compartment, the damper status, the fan status, the electric valve status, and the compressor status.

[0081] After receiving the start and stop parameters transmitted by the controller, the wireless module packages the start and stop parameters into data packets in a fixed format according to the communication protocol with the server and transmits them to the server.

[0082] The server parses the start and stop parameters from the received data packets, and stores the collected temperature sensor values ​​of each compartment, the evaporator sensor temperature values ​​of each compartment, the set temperature of each compartment, the damper status, the fan status, the electric valve status, and the compressor status in the corresponding database. Among them, when the start and stop parameters are stored, they are stored separately according to the time sequence and type. For example, the damper status is set with a time tag and a type tag. When obtaining the damper status, it is necessary to obtain the damper status at a certain time point according to the time tag and the type tag.

[0083] The server queries the data set collected from the refrigerator in the last 48 hours from its database, and calculates the difference between the temperature of each compartment in the database and the set temperature of each compartment in chronological order. If all the differences are greater than the first preset threshold, take one time point as an example, such as: the set temperature of the refrigerator compartment is 5°C, the sensor temperature of the refrigerator compartment is 10°C, the difference is 10°C-5°C=5°C, and the first preset threshold is 4°C, then the difference is greater than the first preset threshold.

[0084] When the calculation is completed, the difference is greater than the second preset threshold. Then the compressor start and stop times are counted from the collected start and stop parameters to determine whether the compressor start and stop times are greater than or equal to the third preset threshold; the compressor switches from the start state to the stop state, which is recorded as one start and stop; if within 48 hours, the compressor start and stop times are 30 times, and the third preset threshold is 20, then the compressor start and stop times are greater than the third preset threshold; and then it is necessary to determine that in each compressor start state, when the direction of the electric valve connecting the refrigeration system is the refrigeration of the refrigerator, and the refrigeration damper and the refrigeration fan are in the open state, and the refrigeration evaporator temperature sensor value is in a downward trend, it indicates that the refrigerator refrigeration system is fault-free and the start and stop parameters need to be adjusted. When the difference is greater than the first preset threshold, the refrigerator is sent to the refrigerator to adjust the start and stop parameters. After receiving the start and stop parameter adjustment instruction, the refrigerator adjusts the start parameters of the refrigerator, such as: the original refrigeration start parameter is 2, and the adjusted refrigeration start parameter is 1; after the start parameter of the refrigerator is adjusted, it will directly lead to the start point of the refrigerator being adjusted downward.

[0085] In addition, according to the first comparison result, the damper state, the fan state, the electric valve state and the evaporator temperature of each compartment, generating the start-stop parameter adjustment instruction also includes:

[0086] If the first comparison result is that the difference is less than the second preset threshold, and the electric valve state is that the damper state and the fan state of the compartment corresponding to the direction in which the electric valve connects to the refrigeration system are open, and the evaporator temperature value is on a downward trend, the start and stop parameters are controlled to be adjusted upward.

[0087] Specifically, the controller of the refrigerator uploads all the start and stop parameters of different ambient temperatures and different compartments to the wireless module at fixed intervals; the start and stop parameters include the temperature of each compartment detected by the temperature sensor of each compartment, the evaporator temperature detected by the evaporator sensor of each compartment, the set temperature of each compartment, the damper status, the fan status, the electric valve status, and the compressor status.

[0088] After receiving the start and stop parameters transmitted by the controller, the wireless module packages the start and stop parameters into data packets in a fixed format according to the communication protocol with the server and transmits them to the server.

[0089] The server parses the start and stop parameters from the received data packets, and stores the collected temperature sensor values ​​of each compartment, the evaporator sensor temperature values ​​of each compartment, the set temperature of each compartment, the damper status, the fan status, the electric valve status, and the compressor status in the corresponding database. Among them, when the start and stop parameters are stored, they are stored separately according to the time sequence and type. For example, the damper status is set with a time tag and a type tag. When obtaining the damper status, it is necessary to obtain the damper status at a certain time point according to the time tag and the type tag.

[0090] The server queries the data set collected from the refrigerator in the last 48 hours from its database, and calculates the difference between the temperature of each compartment in the database and the set temperature of each compartment in chronological order. If all the differences are less than the second preset threshold, take one time point as an example, such as: the set temperature of the refrigerator compartment is 5°C, the sensor temperature of the refrigerator compartment is 2°C, the difference is 2°C-5°C=-3°C, and the second preset threshold is -2°C, then the difference is less than the second preset threshold.

[0091] When the calculation is completed, the difference is less than the second preset threshold. Then the compressor start and stop times are counted from the collected start and stop parameters to determine whether the compressor start and stop times are greater than or equal to the third preset threshold; the compressor switches from the start state to the stop state, which is recorded as one start and stop; if within 48 hours, the compressor start and stop times are 30 times, and the third preset threshold is 20, then the compressor start and stop times are greater than the third preset threshold; and then it is necessary to determine that, in each compressor start state, when the direction of the electric valve connecting the refrigeration system is the refrigeration of the refrigerator, and the refrigeration damper and the refrigeration fan are in the open state, and the refrigeration evaporator temperature sensor value is in a downward trend, it indicates that the refrigerator refrigeration system is fault-free and the start and stop parameters need to be adjusted. When the difference is less than the second preset threshold, the refrigerator is sent to the refrigerator to adjust the start and stop parameter. After receiving the start and stop parameter adjustment instruction, the refrigerator adjusts the start parameter of the refrigerator upward, such as: the original refrigeration start parameter is 2, and the adjusted refrigeration start parameter is 3; after the start parameter of the refrigerator is lowered, it will directly lead to an increase in the start point of the refrigerator.

[0092] In some embodiments, the present application provides a refrigerator, which is applied to the refrigerator startup and shutdown parameter control method provided in the above embodiment. The refrigerator provided in the present application includes:

[0100] Comparing the temperature of each compartment with the set temperature of each compartment to obtain a first comparison result;

[0101] If the first comparison result meets the preset condition, the number of times the compressor is started and stopped is obtained according to the compressor state;

[0102] If the number of compressor start and stop times is greater than the third preset threshold, a start and stop parameter adjustment instruction is generated based on the first comparison result, the damper state, the fan state, the electric valve state and the evaporator temperature of each compartment; the start and stop parameter adjustment instruction is used to control the start and stop parameters of the refrigerator compartment to increase or decrease.

[0103] In some embodiments, the controller is further configured to:

[0104] Calculate the difference between the temperature of each compartment and the set temperature of each compartment in chronological order;

[0105] If the differences are all greater than the first preset threshold or the differences are all less than the second preset threshold, the preset condition is met.

[0108] If the first comparison result is that the difference is less than the second preset threshold, and the electric valve state is that the damper state and the fan state of the compartment corresponding to the direction in which the electric valve connects to the refrigeration system are open, and the evaporator temperature value is on a downward trend, the start and stop parameters are controlled to be adjusted upward.
