[0002] In today's society, the home appliance industry is developing rapidly, and people's lives are becoming more and more intelligent. When the traditional refrigerator reaches the set shutdown point temperature, the refrigerator compressor will be turned off and shut down. After the compartment temperature rises to the set start-up point temperature, the compressor will start again. In this way, the temperature of the refrigerator compartment fluctuates greatly, and the compressor is repeatedly started and stopped at a high speed, which will damage the compressor and reduce its life. In addition, the start and stop of the compressor will generate a large current, which is not conducive to energy saving.

[0068] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0069] To facilitate understanding of the embodiments of the present invention, specific embodiments will be further explained below in conjunction with the accompanying drawings. The embodiments do not constitute a limitation on the embodiments of the present invention.

[0070] Figure 1 A schematic diagram of a flow chart of a first refrigeration equipment control method provided by an embodiment of the present invention, such as Figure 1 As shown, the method specifically includes:

[0071] S11. When the refrigeration device is turned on and the compressor of the refrigeration device is running at an initial speed, obtaining a real-time temperature of a freezer compartment of the refrigeration device within a first time period, and obtaining a first preset temperature of the freezer compartment.

[0072] A refrigeration equipment control method provided in an embodiment of the present invention is applied to a refrigeration equipment, and the refrigeration equipment can realize refrigeration of a freezer compartment by starting compressor refrigeration. The refrigeration equipment may include but is not limited to: a refrigeration equipment, a freezing equipment, a vertical refrigerator, a horizontal refrigerator, etc. Specifically, a control strategy of the compressor is determined by obtaining the real-time temperature and a preset temperature of the freezer compartment of the refrigeration equipment, and the compressor is controlled by the control strategy to realize precise control of the refrigeration temperature of the refrigeration equipment.

[0073] In this embodiment, the compressor of the refrigeration equipment is pre-set with different speed gears (for example, the compressor speed gears are S0-S8 from low to high), and the higher the gear, the greater the cooling capacity. The refrigeration equipment is turned on and operated, including two operating conditions: the first is the first power-on after power failure, and the second is turned on from a normal closed state. In both cases, when the refrigeration equipment is turned on, the refrigeration equipment is controlled to run at a preset initial speed (usually the minimum speed. For example, the gear is S0 in S0-S8), and the real-time temperature of the freezer compartment that needs to be refrigerated in the refrigeration equipment within a preset first time period is obtained during operation. The real-time temperature is used to record the temperature change and obtain the first preset temperature corresponding to the current freezer compartment. The first preset temperature represents the temperature that the freezer compartment needs to reach in the end.

[0074] S12. Determine a control strategy for the refrigeration equipment according to the real-time temperature and the first preset temperature.

[0075] In this embodiment, the real-time temperature can represent the current temperature of the freezing compartment and the temperature change in the first time period. The current real-time temperature and the first preset temperature are preset in different operating conditions, and the corresponding control strategy can include: controlling the compressor speed of the refrigeration equipment to increase, decrease or maintain the current speed, and also including adjusting the compressor speed according to the change of the real-time temperature in the first time period during the compressor speed control process. When determining the control strategy, the current operating conditions are first determined, and then the current real-time temperature and the first preset temperature are judged, and then the corresponding control strategy is determined.

[0076] In a possible implementation manner, determining the control strategy of the refrigeration equipment according to the real-time temperature and the first preset temperature includes:

[0077] When the refrigeration device is powered on for the first time and the real-time temperature is greater than the first preset temperature, the control strategy is determined to be the first strategy, which is used to control the speed of the compressor to increase or maintain the current speed.

[0078] S13. Control the compressor of the refrigeration equipment according to the control strategy.

[0079] In this embodiment, a control instruction is generated according to the control strategy, and the speed of the compressor of the refrigeration equipment is controlled to increase, decrease or maintain the current speed according to the control instruction. Furthermore, in the process of controlling the speed, since the temperature of the refrigeration compartment changes, it is determined whether the change in real-time temperature within the first time period is decreasing, unchanged or increasing, and the current compressor speed is adjusted to increase, decrease or maintain the current speed according to the determination result.

[0080] In a possible implementation manner, controlling the compressor of the refrigeration equipment according to the control strategy includes:

[0081] The first current real-time temperature of the freezer compartment is obtained; at each second time period, the speed of the compressor is controlled to increase by one gear, and the second current real-time temperature of the freezer compartment is obtained; when the first real-time temperature is greater than the second real-time temperature, the compressor is controlled to maintain the current speed; or, when the first real-time temperature is less than or equal to the second real-time temperature, the speed of the compressor is controlled to increase by one gear.

[0082] The refrigeration equipment control method provided by the embodiment of the present invention, when the refrigeration equipment is turned on and the compressor of the refrigeration equipment is running at the initial speed, the real-time temperature of the freezer compartment of the refrigeration equipment in the first time period and the first preset temperature of the freezer compartment are obtained; the control strategy of the refrigeration equipment is determined according to the real-time temperature and the first preset temperature; the compressor of the refrigeration equipment is controlled according to the control strategy. In this way, the refrigeration capacity of the refrigerator compartment can be controlled by controlling the speed of the compressor by the real-time temperature and the preset temperature, thereby reducing the temperature fluctuation of the compartment, and the temperature control of the refrigeration equipment can be more accurately performed, avoiding the sudden shutdown of the compressor at a high speed, and reducing the energy loss of the refrigeration equipment.

[0083] Figure 2 A flow chart of a second refrigeration equipment control method provided by an embodiment of the present invention is shown as follows: Figure 2 As shown, the method specifically includes:

[0084] S21. When the refrigeration device is turned on and the compressor of the refrigeration device is running at an initial speed, obtaining a real-time temperature of a freezer compartment of the refrigeration device within a first time period, and obtaining a first preset temperature of the freezer compartment.

[0085] In this embodiment, the refrigeration device is in the operating state of being powered on for the first time after a power outage. When the refrigeration device is turned on, the refrigeration device is controlled to run at a preset initial speed. During the operation, the real-time temperature of the freezer compartment that needs to be refrigerated in the refrigeration device within a preset first time period is obtained, and the first preset temperature corresponding to the current freezer compartment is obtained. The first preset temperature represents the temperature that the freezer compartment needs to eventually reach.

[0086] Further, the magnitude of the real-time temperature and the first preset temperature is determined, and steps S22-S23 are executed when the real-time temperature is greater than the first preset temperature, and steps S24-S25 are executed when the real-time temperature is less than or equal to the first preset temperature.

[0087] S22, when the refrigeration device is powered on for the first time and the real-time temperature is greater than the first preset temperature, determining that the control strategy is the first strategy, the first strategy is used to control the speed of the compressor to increase or maintain the current speed;

[0088] S23, obtaining a first current real-time temperature of the freezer compartment; controlling the speed of the compressor to increase by one gear every second time period, and obtaining a second current real-time temperature of the freezer compartment; when the first real-time temperature is greater than the second real-time temperature, controlling the compressor to maintain the current speed; or, when the first real-time temperature is less than or equal to the second real-time temperature, controlling the speed of the compressor to increase by one gear.

[0089] In this embodiment, step S22 and step S23 are described uniformly. When the refrigeration device is powered on for the first time, the compressor is first controlled to run at the initial speed. When the current real-time temperature is greater than the first preset temperature, the control strategy is determined to be the first strategy. The current first real-time temperature is obtained and recorded according to the first strategy. After a second time period (e.g., 5 minutes), the compressor speed is controlled to increase by one gear on the basis of the current gear. Then the current second real-time temperature is obtained.

[0090] Furthermore, the magnitude of the first real-time temperature and the second real-time temperature is determined. When the first real-time temperature is greater than the second real-time temperature, it indicates that the current compressor has an obvious cooling effect and the temperature can be quickly reduced to the first preset temperature. At this time, the compressor can be controlled to maintain the current speed, and the steps of obtaining the first real-time temperature, controlling the compressor speed to increase by one gear, and obtaining the second real-time temperature are continued to be executed again at each second time period, until the real-time temperature is less than or equal to the first preset temperature, steps S24-S25 are executed, or when the first real-time temperature is less than or equal to the second real-time temperature, the compressor speed is controlled to increase by one gear.

[0091] S24, when the refrigeration device is powered on for the first time and the real-time temperature is less than or equal to the first preset temperature, determining that the control strategy is the second strategy, the second strategy is used to control the speed of the compressor to reduce or maintain the current speed;

[0092] S25, obtaining a first current real-time temperature of the freezer compartment; obtaining a second current real-time temperature of the freezer compartment at intervals of a second time period; when the first real-time temperature is greater than the second real-time temperature, controlling the speed of the compressor to reduce one gear; or, when the first real-time temperature is less than or equal to the second real-time temperature, controlling the compressor to maintain the current speed.

[0093] In this embodiment, step S24 and step S25 are described uniformly. When the refrigeration device is powered on for the first time, the compressor is first controlled to run at the initial speed. When the current real-time temperature is less than or equal to the first preset temperature, the control strategy is determined to be the second strategy. The first real-time temperature of the current freezing compartment is obtained and recorded according to the second strategy. After a second time period (for example, 5 minutes), the current second real-time temperature is obtained.

[0094] Furthermore, the magnitude of the first real-time temperature and the second real-time temperature is determined. When the first real-time temperature is greater than the second real-time temperature, it indicates that the current compressor is overcooling. The speed of the compressor can be controlled to be reduced by one gear on the current basis. When the first real-time temperature is less than or equal to the second real-time temperature, the speed of the compressor is controlled to maintain the current speed.

[0095] As an example, Figure 6 FIG. 4 is a flow chart of a fourth refrigeration equipment control method provided by an embodiment of the present invention. Figure 8 The figure shows a flow chart of a method for obtaining the temperature of a freezer compartment of a refrigeration device provided by an embodiment of the present invention. The first preset temperature of the freezer compartment is t1. The real-time temperature tx of the freezer compartment is detected and recorded by the temperature sensor a1 of the freezer compartment. When the refrigerator is powered on for the first time after power failure, if tx>t1, the refrigerator compressor is controlled to start, and the speed is the initial speed S0, and the compressor refrigerates the freezer compartment. The compressor speed is increased by one gear every 5 minutes (second time period), which can achieve the purpose of rapid refrigeration while avoiding damage to the compressor due to excessive changes in the compressor speed. If tx≤t1, the compressor is first controlled to run at the initial speed. At this time, the current first real-time temperature is recorded as tx1, and the second real-time temperature of the freezer compartment after 5 minutes is tx2. If tx1>tx2, the compressor speed is reduced by one gear and continues to run until it stops; if tx1≤tx2, the compressor speed remains unchanged and maintains the current speed. At this time, the refrigeration capacity of the compressor is lower than the natural temperature rise of the compartment. Until tx>t1, if tx1≤tx2, the compressor speed will be increased by one gear and continue to run until the maximum speed; if tx1>tx2, the compressor speed will remain unchanged and maintain the current speed. Until tx≤t1, the compressor works in a regular cycle.

[0096] The refrigeration equipment control method provided by the embodiment of the present invention obtains the real-time temperature of the freezer compartment of the refrigeration equipment in the first time period and obtains the first preset temperature of the freezer compartment when the refrigeration equipment is turned on and the compressor of the refrigeration equipment is running at the initial speed. When the refrigeration equipment is powered on for the first time and the real-time temperature is greater than the first preset temperature, the control strategy is determined to be the first strategy; the current first real-time temperature of the freezer compartment is obtained; the speed of the compressor is controlled to increase by one gear every second time period, and the current second real-time temperature of the freezer compartment is obtained; when the first real-time temperature is greater than the second real-time temperature, the compressor is controlled to maintain the current speed; or, when the first real-time temperature is less than or equal to the second real-time temperature, the speed of the compressor is controlled to increase by one gear. When the refrigeration equipment is powered on for the first time and the real-time temperature is less than or equal to the first preset temperature, the control strategy is determined to be the second strategy; the current first real-time temperature of the freezer compartment is obtained; every second time period, the current second real-time temperature of the freezer compartment is obtained; when the first real-time temperature is greater than the second real-time temperature, the speed of the compressor is controlled to decrease by one gear; or, when the first real-time temperature is less than or equal to the second real-time temperature, the compressor is controlled to maintain the current speed. As a result, the compressor speed of the refrigeration equipment can be controlled by real-time temperature changes and preset temperature when the refrigeration equipment is powered on for the first time, and the temperature can be accurately adjusted according to the temperature changes in the freezer compartment of the refrigeration equipment, thereby improving the refrigeration effect and reducing energy consumption.

[0097] Figure 3 A flow chart of a third refrigeration equipment control method provided by an embodiment of the present invention is shown as follows: Figure 3 As shown, the method specifically includes:

[0098] S31. When the refrigeration device is turned on and the compressor of the refrigeration device is running at an initial speed, obtaining a real-time temperature of a freezer compartment of the refrigeration device within a first time period, and obtaining a first preset temperature of the freezer compartment.

[0099] In this embodiment, the refrigeration device is turned on from a normal off state. When the refrigeration device is turned on, the refrigeration device is controlled to run at a preset initial speed. During the operation, the real-time temperature of the freezer compartment that needs to be refrigerated in the refrigeration device within a preset first time period is obtained, and the first preset temperature corresponding to the current freezer compartment is obtained. The first preset temperature represents the temperature that the freezer compartment needs to reach in the end.

[0100] Further, the size between the real-time temperature and the first preset temperature, the second preset temperature and the third preset temperature is determined. When the real-time temperature is greater than the first preset temperature and less than or equal to the second preset temperature, steps S32-S34 are executed. When the real-time temperature is less than or equal to the first preset temperature and greater than the third preset temperature, steps S35-S37 are executed. When the real-time temperature is less than or equal to the third preset temperature, steps S38-S40 are executed.

[0101] S32. During the operation of the refrigeration equipment, when the real-time temperature is greater than the first preset temperature and less than or equal to the second preset temperature, determining that the control strategy is the third strategy, and the difference between the second preset temperature and the first preset temperature is the first preset value;

[0102] S33, controlling the compressor to maintain the current speed; obtaining the third current real-time temperature of the compressor, and obtaining the fourth real-time temperature of the compressor after the compressor runs for the second time period; when the third real-time temperature is less than or equal to the fourth real-time temperature, controlling the speed of the compressor to increase by one gear;

[0103] S34. When the third real-time temperature is greater than the fourth real-time temperature, the compressor is controlled to maintain the current speed until the real-time temperature is less than or equal to the first preset temperature, and then the control strategy is switched to the second strategy.

[0104] In this embodiment, steps S32-S34 are described uniformly, and a second preset temperature is preset. The difference between the second preset temperature and the first preset temperature is the first preset value, that is, the second preset temperature is greater than the first preset temperature, and the second preset temperature is the first preset temperature plus the preset value (for example, the first preset temperature is t1, and the second preset temperature is t1+3). When the refrigeration device enters normal startup and operation from the shutdown state, when the real-time temperature is greater than the first preset temperature and less than or equal to the second preset temperature, the control strategy is determined to be the third strategy, and the compressor is controlled to maintain the current speed according to the third strategy to obtain the current third real-time temperature and the fourth real-time temperature after running at the current speed for a second period of time. When the third real-time temperature is less than or equal to the fourth real-time temperature, it means that the current refrigeration capacity is low and the compressor speed is slow. The speed of the compressor is controlled to increase by one gear on the current basis. When the third real-time temperature is greater than the fourth real-time temperature, it means that the current temperature of the freezing compartment is in a cooling state. The compressor is controlled to maintain the current speed until the real-time temperature is less than or equal to the first preset temperature, which means that the current temperature has dropped to the first preset temperature, and the control strategy is switched to Figure 2 The second strategy is adopted and the compressor is controlled according to the second strategy.

[0105] In one possible implementation, when the refrigeration device enters normal startup and operation from the shutdown state, when the real-time temperature is greater than the second preset temperature, the compressor is controlled to increase one gear on the basis of the current one, and then the compressor is controlled to increase one gear on the basis of the current one every second time period (for example, five minutes) until the current real-time temperature is less than or equal to the first preset temperature. Figure 2 The second strategy in controls the compressor.

[0106] S35. During the operation of the refrigeration equipment, when the real-time temperature is less than or equal to the first preset temperature and greater than the third preset temperature, determining that the control strategy is the fourth strategy, and the difference between the third preset temperature and the first preset temperature is the second preset value;

[0107] S36, controlling the compressor to maintain the current speed; obtaining the third current real-time temperature of the compressor, and obtaining the fourth real-time temperature of the compressor after the compressor runs for the second time period; when the third real-time temperature is greater than the fourth real-time temperature, controlling the speed of the compressor to decrease by one gear;

[0108] S37. When the third real-time temperature is less than or equal to the fourth real-time temperature, control the compressor to maintain the current speed until the real-time temperature is greater than the first preset temperature, and then switch the control strategy to the first strategy.

[0109] In this embodiment, steps S35-S37 are described uniformly, a third preset temperature is preset, and the difference between the third preset temperature and the first preset temperature is the second preset value, that is, the third preset temperature is less than the first preset temperature, and the third preset temperature is the first preset temperature minus the preset value (for example, the first preset temperature is t1, and the third preset temperature is t1-3). When the refrigeration device enters normal startup and operation from the shutdown state, when the real-time temperature is less than or equal to the first preset temperature and greater than the third preset temperature, the control strategy is determined to be the fourth strategy, and the compressor is controlled to maintain the current speed according to the fourth strategy to obtain the current third preset temperature. real-time temperature, and the fourth real-time temperature after running for the second time period at the current speed. When the third real-time temperature is greater than the fourth real-time temperature, it means that the current refrigeration is over-refrigerated and the temperature of the freezing chamber is low. The speed of the compressor is controlled to be reduced by one gear on the current basis. When the third real-time temperature is less than or equal to the fourth real-time temperature, it means that the temperature is currently recovering. Since the current real-time temperature is lower than the first preset temperature to be reached, the compressor can be controlled to maintain the current speed to make the real-time temperature gradually approach the first preset temperature. Until the real-time temperature is greater than the first preset temperature, it means that the temperature has recovered and recovered too high. At this time, the control strategy is switched to Figure 2 The first strategy is adopted and the compressor is controlled according to the first strategy.

[0110] S38. During the operation of the refrigeration equipment, when the real-time temperature is less than or equal to the third preset temperature, determining that the control strategy is the fifth strategy;

[0111] S39, controlling the speed of the compressor to reduce one gear; obtaining the third current real-time temperature of the compressor, and obtaining the fourth real-time temperature of the compressor after the compressor runs for the second time period; when the third real-time temperature is greater than the fourth real-time temperature, controlling the speed of the compressor to reduce one gear;

[0112] S40: When the third real-time temperature is less than or equal to the fourth real-time temperature, the compressor is controlled to maintain the current speed until the real-time temperature is greater than the first preset temperature, and then the control strategy is switched to the first strategy.

[0113] In this embodiment, steps S38-S40 are described uniformly. When the refrigeration device enters normal startup and operation from the shutdown state, when the real-time temperature is less than or equal to the third preset temperature, it means that the current temperature is too low, and the control strategy is determined to be the fifth strategy. According to the fifth strategy, the speed of the compressor is controlled to be reduced by one gear to make the temperature rise, and the current third real-time temperature and the fourth real-time temperature after running at the current speed for the second time period are obtained. When the third real-time temperature is greater than the fourth real-time temperature, it means that the current refrigeration is excessive and the temperature of the freezer compartment is low. The speed of the compressor is controlled to be reduced by one gear on the current basis. When the third real-time temperature is less than or equal to the fourth real-time temperature, it means that the temperature is currently recovering. Since the current real-time temperature is lower than the first preset temperature that needs to be reached, the compressor can be controlled to maintain the current speed to make the real-time temperature gradually approach the first preset temperature. Until the real-time temperature is greater than the first preset temperature, it means that the temperature has recovered and the recovery is too high. At this time, the control strategy is switched to Figure 2 The first strategy is adopted and the compressor is controlled according to the first strategy.

[0114] As an example, Figure 7 The flowchart of the fifth refrigeration equipment control method provided by the embodiment of the present invention is shown. The refrigeration equipment is normally turned on and the compressor is controlled to run at the initial speed. The real-time temperature of the freezing compartment is tx, the first preset temperature is t1, the second preset temperature is t1+3, the third preset temperature is t1-3, the third real-time temperature is tx1, and the fourth real-time temperature is tx2. If tx>t1+3, the compressor is immediately increased by one gear, and then the compressor speed is increased by one gear every 5 minutes (second time period) until tx≤t1, and then according to control rule 1 ( Figure 2 The second strategy in ( ) is used for control.

[0115] If \(t1 + 3\geq tx>t1\), keep the compressor speed unchanged. At this time, record the third real-time temperature of the freezing compartment as \(tx1\), and the fourth real-time temperature of the freezing compartment after 5 minutes as \(tx2\). If \(tx1\leq tx2\), increase the compressor speed by one gear and continue to run; if \(tx1>tx2\), keep the compressor speed unchanged and maintain the current speed. Until \(tx\leq t1\), then follow Control Rule 1 ( Figure 2 the second strategy in

[0116] to control). If \(t1 - 3<tx\leq t1\), keep the compressor speed unchanged. At this time, record the third real-time temperature \(tx1\), and the fourth real-time temperature after 5 minutes as \(tx2\). If \(tx1>tx2\), decrease the compressor speed by one gear and continue to run; if \(tx1\leq tx2\), keep the compressor speed unchanged and maintain the current speed. At this time, the refrigeration capacity of the compressor is already lower than the natural temperature rise of the freezing compartment. Until \(tx>t1\), then follow Control Rule 1 ( Figure 2 the first strategy in

[0117] to control). If \(tx\leq t1 - 3\), immediately decrease the compressor speed by one gear. At this time, record the third real-time temperature as \(tx1\), and the fourth real-time temperature after 5 minutes as \(tx2\). If \(tx1>tx2\), decrease the compressor speed by one gear and continue to run; if \(tx1\leq tx2\), keep the compressor speed unchanged and maintain the current speed. At this time, the refrigeration capacity of the compressor is already lower than the natural temperature rise of the freezing compartment. Until \(tx>t1\), then follow Control Rule 1 ( Figure 2 the first strategy in

[0118] In a possible implementation, when the refrigeration device enters the defrost cycle, control the compressor to stop; control the defrost heater of the refrigeration device to defrost; when the evaporator temperature of the refrigeration device is greater than the preset temperature, stop defrosting, and perform the step of determining the control strategy of the refrigeration device according to the real-time temperature and the first preset temperature.

[0119] In this embodiment, when it is detected that the refrigeration device enters the defrost cycle, control the compressor to stop and control the defrost heater to work for defrosting. Judge whether the defrost cycle is over according to the temperature sensor a2 on the evaporator. When the temperature of the temperature sensor a2 is greater than the preset temperature (for example, eight degrees), control the refrigeration device to exit the defrost cycle. At this time, the refrigeration device executes the control according to Figure 3 S31 - S40 in

[0120] The refrigeration equipment control method provided by the embodiment of the present invention controls the compressor speed of the refrigeration equipment by comparing the real-time temperature with multiple preset temperatures and judging the real-time temperature change during the operation of the refrigeration equipment after it is turned on from a normal shutdown state. The temperature can be accurately adjusted according to the temperature change of the freezer compartment of the refrigeration equipment. By adjusting the compressor speed, it is avoided to suddenly shut down or start the compressor to prevent damage to the compressor. At the same time, there is no need to repeatedly start and stop the compressor, which can reduce the time required for refrigeration, improve the refrigeration efficiency and effect, and reduce energy consumption.
