Description

TECHNICAL FIELD

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

[0002] With the development of technology and the improvement of people's living standards, the refrigerator has become a necessity for every family. At present, the refrigerator is mostly air-cooled refrigerator, which is a refrigerator that uses a fan to circulate air to achieve cooling. In the air-cooled refrigerator, the cooler reduces the temperature inside the refrigerator by blowing cold air out of the fan. This cold air is evenly distributed to all parts of the refrigerator, thereby achieving overall refrigeration.

[0003] The compressor is the core component of the refrigerator refrigeration. An important parameter for controlling the start and stop of the compressor is the start-stop temperature point, which is usually calculated by a fixed formula from the refrigerator set temperature and the start-stop parameter. The start-stop parameter is obtained through performance matching test in the laboratory. The start-stop parameters of the same model refrigerator, or even the same series of refrigerators with the same structure, are generally the same. However, due to the assembly deviation of the production line and the difference in the working conditions of the user using the refrigerator, the refrigeration effect of the refrigerator is greatly different even under the same start-stop parameter. Therefore, there may be phenomena such as poor refrigeration effect of the refrigerator, no refrigeration of the refrigerator, and too low temperature in the refrigerator.

[0004] In view of the above abnormal problems, the common method is to arrange after-sales personnel to adjust the start-stop parameters of the refrigerator to solve the problem. However, the adjustment of the start-stop parameters of the refrigerator by the after-sales personnel will increase the cost of after-sales service on the one hand. On the other hand, since there are corresponding start-stop parameters under different compartments and different ambient temperatures, the number of start-stop parameters is large, and the start-stop parameters are generally represented by special symbols composed of letters and numbers. When adjusting the start-stop parameters, the after-sales personnel may make mistakes in adjusting the start-stop parameters, and cannot timely adjust the start-stop parameters of the compartments of the refrigerator.

BRIEF DESCRIPTION OF DRAWINGS

[0045] In order to more clearly illustrate the technical scheme of the present application, the following will briefly introduce the drawings needed to be used in the embodiments. Obviously, for those skilled in the art, other drawings can also be obtained without creative labor based on these drawings.

[0046] Figure 1 The refrigerator start-stop parameter control method flowchart provided by the embodiments of the present application. DETAILED DESCRIPTION

[0047] The embodiments will be described in detail below, and examples are shown in the drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following embodiments do not represent all embodiments consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as described in detail in the claims.

[0048] The refrigerator provided by the embodiments of the present application is a refrigeration device, in order to realize refrigeration and operation, at least comprising a refrigeration system, a cooling system, a control system and a cabinet. Among them, the refrigeration system is used to generate refrigeration effect, the cooling system is used to maintain low temperature environment, the control system is used to control 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 comprise specific components that can realize the above functions.

[0049] In some embodiments, the refrigeration system includes a compressor, a condenser, an evaporator, and a throttling device. The compressor is used to compress the refrigerant gas, increase the pressure and temperature, and thus drive the refrigerant to flow in the system. During the compression process, the refrigerant changes from a low-pressure low-temperature gas to a high-pressure high-temperature gas, thereby generating a refrigeration effect. The condenser is used to cool the high-temperature high-pressure gas discharged by the compressor into a liquid state. The refrigerant gas is converted into a liquid state by releasing heat through the heat sink, and is ready for 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 gaseous state in the evaporator, absorbs heat from the surrounding environment, and thus achieves the purpose of reducing the temperature inside the refrigerator. The throttling device can include an expansion valve and a capillary tube, which is used to regulate the flow of refrigerant, reduce its pressure, and change it into a low-temperature low-pressure gas-liquid mixed state, ready for 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 compartment and the refrigerator compartment, transfers heat to the evaporator, and helps maintain a low-temperature environment inside the refrigerator.

[0051] It should be noted that the above examples are only a simple division of the functions of the refrigerator, and do not limit the specific structure of the refrigerator in the embodiments of the present application.

[0052] The compressor is the core component of the refrigerator, and the important parameter for controlling the start and stop of the compressor is the start and stop temperature point, which is usually calculated by a fixed formula from the refrigerator set temperature and the start and stop parameters. The start and stop parameters are obtained through performance matching tests in the laboratory. The start and stop parameters of the same model refrigerator, or even the same series of refrigerators with the same structure, are generally the same. However, due to the deviation of the production line assembly and the difference in the working conditions of the refrigerator used by the user, even under the same start and stop parameters, the refrigeration effect of the refrigerator differs greatly. Therefore, there may be problems such as poor refrigeration effect of the refrigerator, no refrigeration of the refrigerator, and too low temperature in the refrigerator compartment.

[0053] To solve the above-mentioned abnormal problems, the common practice is to arrange after-sales personnel to adjust the start and stop parameters of the refrigerator on site. However, the adjustment of the start and stop parameters of the refrigerator by the after-sales personnel on site will increase the cost of after-sales service on one hand, and on the other hand, due to the existence of corresponding start and stop parameters under different compartments and different ambient temperatures, the number of start and stop parameters is large, and the start and stop parameters are generally represented by special symbols composed of letters and numbers. When adjusting the start and stop parameters, there is a risk of adjusting the start and stop parameters incorrectly, and the start and stop parameters of the compartments of the refrigerator cannot be adjusted in time.

[0054] To solve the problem of low efficiency and even incorrect adjustment caused by manual adjustment of the start and stop parameters of the compartments of the refrigerator, see Figure 1The refrigerator start-stop parameter control method provided in some embodiments of the present application comprises:

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

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

[0057] For example, the temperature of each compartment can include the temperature of the refrigeration compartment, the temperature of the refrigeration compartment, and the temperature of the variable temperature compartment. The temperature of the refrigeration compartment can be obtained by a temperature sensor arranged in the refrigeration compartment, the temperature of the refrigeration compartment can be obtained by a temperature sensor arranged in the refrigeration compartment, and the temperature of the variable temperature compartment can be obtained by a temperature sensor arranged in the variable temperature compartment. The state of the air door and the state of the fan both include the open state and the closed state. The state of the electric valve includes the direction of the electric valve connected to the refrigeration system, for example, when the refrigeration compartment is refrigerated, the direction of the electric valve connected to the refrigeration system is towards the refrigeration evaporator, and when the freezer compartment is refrigerated, the direction of the electric valve connected to the refrigeration system is towards the freezer evaporator. The temperature of the evaporator of each compartment can be obtained by an evaporator temperature sensor, for example, the refrigeration compartment is provided with a refrigeration evaporator corresponding to the refrigeration compartment, the freezer compartment is provided with a freezer evaporator corresponding to the freezer compartment, the refrigeration evaporator is provided with a temperature sensor, and the freezer evaporator is provided with a temperature sensor, so that the temperature of the refrigeration evaporator and the temperature of the freezer evaporator can be obtained respectively.

[0058] The start-stop parameters of each compartment of the refrigerator are sent to the server, which specifically comprises:

[0059] The controller obtains the start-stop parameters of each compartment of the refrigerator at a preset interval;

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

[0061] The server parses the data packet to obtain the start-stop parameters.

[0062] For example, the controller reads and records the start-stop parameters of each compartment of the refrigerator every five minutes, and then the controller transmits the collected start-stop parameters to the wireless device. The wireless device combines and packages the start-stop parameters into a data packet according to a predetermined communication protocol, such as any one of 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, so as to ensure that the data packet can be correctly parsed and processed.

[0063] The wireless device sends the packaged data packet to the server through a wireless network, such as a home Wi-Fi network. After the server receives the data packet from the wireless device of the refrigerator, the server parses the received data packet using a corresponding communication protocol analysis tool.

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

[0065] Table 1: On-off parameter storage table

[0066]

[0067] Among them, the on-off parameters after parsing can be stored according to the data type, and when needed, the required information can be directly extracted from the table.

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

[0069] According to the time sequence, the difference between the temperature of each compartment and the set temperature of each compartment is calculated in turn;

[0070] If the difference is greater than a first preset threshold or the difference is less than a second preset threshold, the preset condition is met.

[0071] It can be understood that when obtaining the on-off parameters, each group of on-off corresponds to an on-off parameter collection time point. According to the time sequence, the difference between the temperature of each compartment and the set temperature of each compartment is calculated in turn. Taking Table 1 as an example, first calculate the difference between the temperature of each compartment and the set temperature of each compartment at 12:05, and then calculate the difference between the temperature of each compartment and the set temperature of each compartment at 12:10. For example, the first preset threshold is 4℃, the set temperature of the refrigeration compartment is 5℃, the temperature of the refrigeration compartment detected by the temperature sensor at 12:10 is 10℃, and the difference is 5℃. The temperature of the refrigeration compartment detected by the temperature sensor at 12:15 is 11℃, and the difference is 6℃. The temperature of the refrigeration compartment detected by the temperature sensor at 12:20 is 10℃, and the difference is 5℃. After calculating in turn, when all the differences are greater than the first preset threshold, the preset condition is met.

[0072] In addition, similarly, when the difference between the temperature of each compartment and the set temperature of each compartment is calculated in turn according to the time sequence, the preset condition can also be met when the difference is less than the second preset threshold.

[0073] S300: If the first comparison result meets the preset condition; then according to the state of the compressor, the number of on-off times of the compressor is obtained;

[0074] According to the time sequence, the compressor state is acquired; the compressor state comprises a compressor start state and a compressor stop state;

[0075] The number of times that the compressor state changes from the compressor start state to the compressor stop state is acquired; the number of times that the compressor start state changes to the compressor stop state is the compressor start-stop number.

[0076] The compressor start-stop number is the number of times that the compressor changes from the start state to the stop state, as shown in Table 1, at 12:15, the compressor state is start, at 12:20, the compressor state is stop, and therefore, the compressor is in the start-stop state from 12:15 to 12:20, and the compressor start-stop number is increased by one. In the embodiment of the application, when the compressor start-stop number in 48 hours is required to be acquired, the data of the compressor state can be traversed according to the time sequence, and the number of times that the compressor state changes from the start state to the stop state is acquired, and the compressor start-stop number is acquired.

[0077] S400: If the compressor start-stop number is greater than the third preset threshold value, a start-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-stop parameter adjustment instruction is used to control the start-stop parameter of the refrigerator compartment to be adjusted upward or downward.

[0078] Specifically, the start-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, and comprises:

[0079] If the first comparison result is that all the differences are greater than the first preset threshold value, the electric valve state is that the electric valve is connected to the direction of the damper state and the fan state of the corresponding compartment, the damper state and the fan state are in the start state, and the evaporator temperature value is in a downward trend, the start-stop parameter is controlled to be adjusted downward.

[0080] The controller of the refrigerator uploads all the start-stop parameters of different ring temperatures and different compartments to the wireless module every fixed time interval; the start-stop parameters comprise 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 state, the fan state, the electric valve state, and the compressor state.

[0081] After the wireless module receives the start-stop parameters transmitted by the controller, the start-stop parameters are packaged into a data packet in a fixed format according to the communication protocol with the server, and then transmitted to the server.

[0082] The server parses the start-stop parameters from the received data packet; and stores the collected temperature sensor values of each compartment, the temperature sensor values of each compartment evaporator, the set temperature of each compartment, the damper state, the fan state, the electric valve state, and the compressor state into the database. Among them, when storing the start-stop parameters, they are stored in time sequence and type respectively. For example, the damper state is provided with a time label and a type label, and when obtaining the damper state, the damper state at a certain time point needs to be obtained according to the time label and the type label.

[0083] The server queries the data set collected from the refrigerator within the last 48 hours from the database in time sequence, and calculates the difference between the temperature of each compartment and the set temperature of each compartment in the database. If all the differences are greater than the first preset threshold value, 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 value is 4°C, then the difference is greater than the first preset threshold value.

[0084] When the calculation is completed, if all the differences are greater than the second preset threshold value, the number of compressor start-stop times is counted from the collected start-stop parameters, and it is judged whether the number of compressor start-stop times is greater than or equal to the third preset threshold value; the compressor switches from the start state to the stop state, which is recorded as one start-stop; if the number of compressor start-stop times is 30 within 48 hours, and the third preset threshold value is 20, then the number of compressor start-stop times is greater than the third preset threshold value; and then it needs to be judged that when the compressor is in the start state, the direction of the electric valve connecting the refrigeration system is the refrigeration compartment refrigeration, and the refrigerator damper and the refrigerator fan are in the open state, and the temperature sensor value of the refrigerator evaporator is in a downward trend, which indicates that the refrigerator refrigeration system is not faulty, and the start-stop parameters need to be adjusted. When all the differences are greater than the first preset threshold value, a command of lowering the refrigerator start parameters is sent to the refrigerator, and after receiving the start-stop parameter adjustment command, the refrigerator lowers the refrigerator start parameters, such as the original refrigerator start parameters are 2, and the adjusted refrigerator start parameters are 1; after the refrigerator start parameters are lowered, the refrigerator start point will be directly lowered.

[0085] In addition, generating the 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 further includes:

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

[0087] Specifically, the controller of the refrigerator uploads all the opening and stopping parameters of different ring temperatures and different compartments to the wireless module every fixed time interval; wherein, the opening and stopping parameters include the temperatures of each compartment detected by the temperature sensors of each compartment, the evaporator temperature detected by the evaporator sensor of each compartment, the set temperature of each compartment, the damper state, the fan state, the electric valve state, and the compressor state.

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

[0089] The server parses the opening and stopping parameters from the received data packets; and stores the collected values of the temperature sensors of each compartment, the temperature values of the evaporator sensors of each compartment, the set temperature of each compartment, the damper state, the fan state, the electric valve state, and the compressor state into the corresponding database. When storing the opening and stopping parameters, they are stored in time sequence and by type respectively. For example, the damper state is provided with a time label and a type label, and when obtaining the damper state, the damper state at a certain time point needs to be obtained according to the time label and the type label.

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

[0091] After the calculation is completed, if all the differences are less than the second preset threshold value, the number of compressor start-stop times is counted from the collected opening and stopping parameters, and it is determined whether the number of compressor start-stop times is greater than or equal to the third preset threshold value; the compressor switches from the start state to the stop state, which is counted as one start-stop; if the number of compressor start-stop times is 30 within 48 hours, and the third preset threshold value is 20, then the number of compressor start-stop times is greater than the third preset threshold value; further, it is determined that when the electric valve is connected to the refrigeration system in the start state of the compressor, 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, then it indicates that the refrigerator refrigeration system is not malfunctioning, and the opening and stopping parameters need to be adjusted; when all the differences are less than the second preset threshold value, an instruction to increase the refrigeration compartment start parameter is sent to the refrigerator, and after receiving the opening and stopping parameter adjustment instruction, the refrigerator increases the refrigeration compartment start parameter, such as: the original refrigeration start parameter is 2, and the adjusted refrigeration start parameter is 3; after the refrigeration compartment start parameter is decreased, the refrigeration compartment start point will be directly increased.

[0101] if the first comparison result meets a preset condition, then the start-stop times of the compressor are obtained according to the state of the compressor;

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

[0104] calculate the differences between the temperatures of the compartments and the set temperatures of the compartments in time sequence;

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