[0002] As people's quality of life improves, larger cross-door refrigerators and French-style four-door refrigerators are gradually becoming the mainstream in the market. At present, the temperature sensors responsible for collecting ambient temperature in most cross-door refrigerators and French-style four-door refrigerators are placed inside the hinge cover of the refrigerator door. Figure 1 The figure shows the location of the temperature sensor on the refrigerator. Figure 1 As shown, the temperature sensor is connected to the environment through the hole opened on the side of the hinged cover to sense the ambient temperature.

[0003] However, since the refrigerator condenser is attached to the side panels on both sides of the refrigerator, when the compressor starts cooling, the heat generated by the condenser will affect the inside of the hinged cover, causing the temperature inside the hinged cover to rise, resulting in a difference between the temperature at the location of the temperature sensor and the actual ambient temperature. At this time, the temperature collected by the temperature sensor will deviate, that is, the detected temperature > ambient temperature.

[0067] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0068] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0069] In order to solve the problem in the prior art that the heat generated by the condenser when dissipating heat will affect the temperature sensor inside the hinged cover, resulting in inaccurate ambient temperature collected by the temperature sensor, and further, causing the operating speed of the compressor to not match the current ambient temperature, resulting in extra power consumption due to excessive speed of the refrigerator compressor, the present application provides a compressor control method, which can correct the initial ambient temperature data collected by the temperature sensor through the real-time speed of the refrigerator compressor, so as to ensure the accuracy of the ambient temperature data, and then control the refrigerator compressor to run at a corresponding speed according to the accurate ambient temperature data, so as to ensure that the operating speed of the refrigerator compressor matches the current ambient temperature, thereby avoiding the problem of extra power consumption due to excessive speed of the refrigerator compressor.

[0070] Figure 2 The flowchart of an embodiment of a compressor control method provided in the present application is shown in FIG. In one embodiment, the method is applied to a refrigeration device, such as a refrigerator. Figure 2 As shown, the method comprises the following steps:

[0071] Step 201: obtain the real-time rotation speed of the refrigerator compressor, and obtain the initial ambient temperature data collected by the temperature sensor disposed outside the refrigerator.

[0072] Step 202: Correct the initial ambient temperature data according to the real-time rotation speed to obtain target ambient temperature data.

[0073] For ease of understanding, step 201 and step 202 are described in a unified manner as follows:

[0074] The embodiment of the present application provides a compressor control method, the execution subject of which may be a control system on a refrigerator, and is applied to Figure 1 The ambient temperature collected by the temperature sensor shown in the figure will be affected by the heat dissipation of the refrigerator condenser, such as Figure 1 As shown, the temperature sensor of the refrigerator is located in the hinge cover above the refrigerator door, and the ambient temperature is collected through the opening on the side of the hinge cover.

[0075] The above real-time rotation speed is used to represent the rotation speed of the refrigerator compressor at the time of collection.

[0076] The above initial ambient temperature data is used to represent the ambient temperature value directly collected by the temperature sensor.

[0077] In an embodiment of the present application, the real-time rotation speed of the refrigerator compressor and the initial ambient temperature data collected by the temperature sensor can be periodically collected, and the real-time rotation speed of the refrigerator compressor and the initial ambient temperature data can be fed back to the control system. The control system corrects the initial ambient temperature data according to the real-time rotation speed of the refrigerator compressor to obtain the target ambient temperature data, that is, the correct ambient temperature data.

[0078] In another embodiment of the present application, before obtaining the real-time rotation speed of the refrigerator compressor, the method further includes:

[0079] Step A1: when the refrigerator compressor is in a stopped state, determining the initial ambient temperature data as the target ambient temperature data;

[0080] Step A2, when the refrigerator compressor is in operation, execute the step of obtaining the real-time rotation speed of the refrigerator compressor, and obtaining the initial ambient temperature data collected by the temperature sensor arranged outside the refrigerator, and correcting the initial ambient temperature data according to the real-time rotation speed to obtain the target ambient temperature data.

[0081] In this embodiment, when the refrigerator compressor is in a shutdown state, that is, the refrigerator compression molding machine is not currently running and the condenser is not dissipating heat, the control system obtains a signal that the compressor speed is 0, and it is assumed that the initial ambient temperature data collected by the temperature sensor at this time is the same as the actual ambient temperature. Therefore, the initial ambient temperature data is directly determined as the target ambient temperature data.

[0082] When the refrigerator compressor is in operation, the heat generated by the condenser when dissipating heat gradually affects the inside of the hinged cover. At this time, the real-time speed of the compressor is fed back to the control system, and the control system corrects the initial ambient temperature data according to the real-time speed of the refrigerator compressor to obtain the target ambient temperature data, thereby correcting the deviation in the ambient temperature data collected by the temperature sensor caused by the influence of the heat generated by the condenser when dissipating heat on the inside of the hinged cover.

[0083] Through this solution, when the compressor is not running and the condenser is not dissipating heat, the initial ambient temperature data collected by the temperature sensor can be directly used as the target ambient temperature data. Only when the compressor is running and the condenser is dissipating heat, the compressor speed is obtained, and the initial ambient temperature data collected by the temperature sensor is corrected according to the compressor speed. In this way, the calculation amount of the control system can be reduced and the calculation efficiency can be improved.

[0084] Step 203: Determine a target rotation speed according to the target ambient temperature data.

[0085] Step 204: Control the refrigerator compressor to operate according to the target speed.

[0086] For ease of understanding, step 203 and step 204 are described in a unified manner as follows:

[0087] In an embodiment of the present application, after obtaining the target ambient temperature data that matches the actual ambient temperature, the target speed corresponding to the target ambient temperature data can be determined based on the correspondence between the preset ambient temperature and the speed, and the refrigerator compressor can be controlled to operate at the target speed, thereby ensuring that the speed of the compressor matches the current actual ambient temperature, thereby avoiding the problem of extra power consumption in the refrigerator due to excessively high compressor speed.

[0088] The technical solution provided by the embodiment of the present application first obtains the real-time rotation speed of the refrigerator compressor, and obtains the initial ambient temperature data collected by the temperature sensor disposed outside the refrigerator, then corrects the initial ambient temperature data according to the real-time rotation speed to obtain the target ambient temperature data, and determines the target rotation speed according to the target ambient temperature data, and finally controls the operation of the refrigerator compressor according to the target rotation speed. In the present application, the initial ambient temperature data collected by the temperature sensor is corrected by the real-time rotation speed of the refrigerator compressor to ensure the accuracy of the ambient temperature data, and then the refrigerator compressor is controlled to operate at a corresponding rotation speed according to the accurate ambient temperature data, so as to ensure that the rotation speed of the refrigerator compressor matches the current ambient temperature, thereby avoiding the problem of extra power consumption due to excessively high rotation speed of the refrigerator compressor.

[0089] Figure 3 A flowchart of an embodiment of the present application is provided for correcting the initial ambient temperature data according to the real-time rotation speed to obtain the target ambient temperature data. Figure 3 The process shown in Figure 2 Based on the process shown, the following steps are included:

[0090] Step 301: Determine a correction parameter according to the real-time rotation speed, wherein the larger the real-time rotation speed is, the larger the corresponding correction parameter is.

[0091] Step 302: Subtract the correction parameter from the initial ambient temperature data to obtain a value as the target ambient temperature data.

[0092] For ease of understanding, step 301 and step 302 are described in a unified manner as follows:

[0093] In the embodiment of the present application, the specific implementation of determining the correction parameter according to the real-time rotation speed may include the following steps:

[0094] Step A1, obtaining a target correspondence table, wherein the target correspondence table contains correspondences between multiple sets of rotation speeds and parameter values;

[0095] Step A2: searching the target correspondence table for a parameter value corresponding to the real-time rotation speed, and determining the parameter value as the correction parameter.

[0096] In this implementation, a correspondence table including a plurality of sets of correspondences between rotation speeds and parameter values ​​as shown in Table 1 may be preset.

[0097] Table 1

[0098] Compressor speed S0 S1 S2 S3 S4 Correction parameter corresponding value 0 0.3 0.5 0.8 1.0

[0099] After the real-time rotation speed of the refrigerator compressor is obtained, the parameter value corresponding to the real-time rotation speed can be found by looking up the table, and then the parameter value is determined as the correction parameter.

[0100] Furthermore, the obtaining of the target correspondence table may specifically include the following steps: determining the distance between the temperature sensor and the refrigerator condenser, and in a preset correspondence table set, determining the correspondence table corresponding to the distance as the target correspondence table.

[0101] Specifically, the distance between the temperature sensor and the refrigerator condenser may be determined according to the refrigerator model, or the distance input by the user may be determined as the distance between the temperature sensor and the refrigerator condenser.

[0102] In practical applications, different corresponding relationship tables may be pre-set for different distances, wherein the closer the distance between the temperature sensor and the refrigerator condenser is, the greater the correction parameter value corresponding to the compressor speed is.

[0103] Based on this, in this embodiment, the target correspondence table can be determined in the preset correspondence table set according to the distance between the temperature sensor and the refrigerator condenser. In this way, the obtained correction parameters can be made more accurate.

[0104] After the correction parameter is obtained, the target ambient temperature data is obtained by subtracting the correction parameter from the initial ambient temperature data, that is, the target ambient temperature data=initial ambient temperature data-correction parameter.

[0105] In a specific example, the initial ambient temperature data is 27 degrees, and the compressor speed is S3. According to Table 1, it can be obtained that the correction parameter corresponding to the compressor speed is 0.8, and the target ambient temperature data = 27-0.8 = 26.2 degrees.

[0106] Figure 3 In the process shown, first, the correction parameter is determined according to the real-time rotation speed, and then the target ambient temperature data is obtained by subtracting the correction parameter from the initial ambient temperature data, thereby correcting the initial ambient temperature data and ensuring the accuracy of the ambient temperature data.

[0107] Figure 4 A flow chart of an embodiment of the present application for obtaining the real-time rotation speed of a refrigerator compressor. Figure 4 The process shown in Figure 2 Based on the process shown, the following steps are included:

[0108] Step 401: collecting the current rotation speed of the refrigerator compressor at a first preset time interval;

[0109] Step 402: determine whether the current rotation speed is the same as the rotation speed collected in the previous cycle;

[0110] Step 403: if the current rotation speed is different from the rotation speed collected in the previous cycle, start timing from the moment when the current rotation speed is collected;

[0111] Step 404: When the timing reaches a second preset time length and the current speed does not change within the second preset time length, the current speed is used as the real-time speed.

[0112] For ease of understanding, steps 401 to 404 are described in a unified manner as follows:

[0113] In the embodiment of the present application, each time the current speed of the refrigerator compressor is collected, if the current speed is the same as the speed collected in the previous cycle, the correction parameters of the current cycle are the same as those of the previous week. If the current speed is different from the speed collected in the previous cycle, in order to make the correction parameter setting more reasonable, it is not directly used as the real-time speed for the ambient temperature correction adjustment process, but the ambient temperature correction adjustment process is performed after the influence of the evaporator heat dissipation is stabilized, that is, after the current speed has not changed for a second preset time (such as 1 minute), the current speed is determined as the real-time speed, and the correction parameters are determined using the real-time speed. In this way, the accuracy of the ambient temperature correction adjustment can be improved.

[0114] In addition, in another embodiment of the present application, the method may further include the following steps:

[0115] Step B1, when the current speed changes before the timing reaches the second preset time, start timing from the time when the speed changes;

[0116] Step B2: When the timing reaches a second preset time length and the changed rotational speed does not change again within the second preset time length, the changed rotational speed is used as the real-time rotational speed.

[0117] From the above description, it can be seen that if the collected current speed changes during the timing process, the timing will be restarted from the time the speed changes until the changed speed remains unchanged for a second preset time period. The speed at this time will be used as the real-time speed, and the ambient temperature correction adjustment will be performed to improve the accuracy of the ambient temperature correction adjustment.

[0118] Figure 4 The process shown in the figure allows the influence of the evaporator heat dissipation to stabilize before the ambient temperature correction adjustment process is performed, that is, after the current speed remains unchanged for a second preset time, the current speed is determined as the real-time speed, and the correction parameter is determined using the real-time speed, thereby improving the accuracy of the ambient temperature correction adjustment.

[0137] When the current speed is different from the speed collected in the previous cycle, timing starts from the time when the current speed is collected;

[0138] When the timing reaches a second preset time length and the current rotation speed does not change within the second preset time length, the current rotation speed is used as the real-time rotation speed.

[0139] In a possible implementation manner, the acquisition module is further used to:

[0140] If the current speed changes before the timing reaches the second preset time, the timing starts from the time when the speed changes;

[0142] In a possible implementation manner, the device further includes an execution module, configured to:

[0145] The technical solution provided by the embodiment of the present application first obtains the real-time rotation speed of the refrigerator compressor, and obtains the initial ambient temperature data collected by the temperature sensor disposed outside the refrigerator, then corrects the initial ambient temperature data according to the real-time rotation speed to obtain the target ambient temperature data, and determines the target rotation speed according to the target ambient temperature data, and finally controls the operation of the refrigerator compressor according to the target rotation speed.
