The existing air-cooled refrigerator with a single system and multiple chambers and only a refrigeration sensor for controlling a compressor and a fan to synchronously start and stop has the following problems that when the ambient temperature is close to the temperature of the refrigeration chamber, the cold quantity requirement of the refrigeration chamber is very small, so the starting rate of the compressor is very low, the temperature of a refrigerating chamber for passive refrigeration cannot reach the target temperature requirement of minus 18 ℃, and when the ambient temperature is lower, the problems that the compressor cannot be started and the refrigerator fails to operate can even occur.

At present, the main solution in the industry is to add a compensation heater in the refrigeration, when the ambient temperature is lower than a certain value, the heater is started to perform compensation heating on the refrigeration chamber so as to increase the cold quantity demand of the refrigeration chamber, and further increase the on-time rate of the compressor, so that the refrigeration is pulled to a lower temperature. In addition, in some schemes, a shifting air door capable of being manually adjusted is arranged in the refrigerating air duct, and the size of an air supply outlet of the refrigerating chamber is adjusted, so that the refrigerating capacity obtained in unit time of the refrigerating chamber is less, and the starting rate is increased.

However, the above solution requires a heater or a damper, so that the number of components of the refrigerator increases and the cost increases.

Therefore, in order to solve the above problems, the present application proposes a control method of a refrigerator and a refrigerator. The present application will be further described with reference to the accompanying drawings and embodiments.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present application, and fig. 2 is a schematic flow chart of a control method of the refrigerator according to the embodiment of the present application. The embodiment of the application provides a refrigerator 100, the refrigerator 100 includes a box body 10 and a processor 40, wherein a storage space 120 and a freezing space 110 arranged below the storage space 120 are defined in the box body 10, a compressor 30 and a fan 20 are arranged in the freezing space 110, the compressor 30 is used for refrigerating, and the fan 20 is used for cooperating with the compressor 30 to refrigerate the storage space 120.

The storage space 120 may be configured as one or more as needed. When the storage space 120 is one, the storage space 120 may be a temperature-changing space or a refrigerating space. When the storage spaces 120 are two or more, the plurality of storage spaces 120 include at least one or more of a temperature changing space and a refrigerating space. In the implementation of the technical solution, a person skilled in the art may configure the number of the storage spaces 120 and the functions thereof as required. The storage space 120 is taken as a refrigerating space in the embodiment of the present application for illustration, and should not be construed as a limitation thereof.

The processor 40 is connected to the compressor 30 and the fan 20, and the processor 40 is configured to execute a control method of the refrigerator 100, where a specific flow of the control method of the refrigerator 100 can refer to fig. 2, and fig. 2 is a schematic flow chart of the control method of the refrigerator provided in the embodiment of the present application. The specific flow of the control method of the refrigerator 100 is as follows:

101. ambient temperature and compressor down time are obtained.

In some embodiments, the refrigerator 100 includes a temperature sensor coupled to the processor 40 for collecting an ambient temperature at which the refrigerator 100 is located and transmitting the collected ambient temperature to the processor 40.

It should be noted that the embodiment of the present application mainly addresses the problem that the refrigerator 100 fails to operate when the ambient temperature is low, and therefore, the operation rule of the embodiment of the present application is applied to the case that the ambient temperature is low, and it should be understood that the embodiment of the present application is described by taking the low temperature as an example of being less than or equal to 13 ℃, and should not be construed as a limitation thereto.

In some embodiments, the refrigerator 100 includes a first timer connected to the processor 40 for counting the shutdown time of the compressor 30 and transmitting the shutdown time of the compressor 30 to the processor 40.

102. And acquiring a corresponding time length threshold according to the interval of the environment temperature.

Based on the captured ambient temperature, a time threshold for shutdown is determined that the compressor 30 should meet.

Wherein the time duration threshold of the compressor 30 is inversely proportional to the ambient temperature.

For example, if the ambient temperature reaches a first preset temperature, the shutdown time needs to reach the first preset time. If the ambient temperature reaches a second preset temperature, stopping the machine for a second preset time; the first preset temperature is higher than the second preset temperature, and the first preset time is shorter than the second preset time.

Illustratively, the time threshold for shutdown of the compressor 30 is 25 minutes when the ambient temperature is in the range of 8 ℃ to 13 ℃. The time threshold for shutdown of the compressor 30 is 50 minutes when the ambient temperature is in the range of 3 ℃ to 8 ℃. The time threshold for shutdown of the compressor 30 is 90 minutes when the ambient temperature is less than 3 ℃.

It should be noted that in some embodiments, the refrigerating space of the refrigerator 100 is provided with a shift button for adjusting the control range of the temperature in the refrigerator 100. The time threshold for the shutdown of the compressor 30 will vary when the shift button is in a different gear, for example, if the ambient temperature is 10 ℃, the time threshold for the shutdown of the compressor 30 is 18 minutes when the shift button is in a strong gear. When the shift button is in the middle or weak range, the time threshold for shutdown of the compressor 30 is 25 minutes.

It is understood that the specific distribution of the ambient temperature and the time threshold for the shutdown are set according to actual conditions, and are not particularly limited herein.

103. If the compressor is off for a period of time greater than the time threshold, the compressor 30 and fan 20 are turned on.

When the shutdown time of the compressor 30 is longer than the time threshold, the compressor 30 and the fan 20 are forcibly started, and refrigeration is performed through the compressor 30 and the fan 20.

Compared with the prior art, when ambient temperature is lower, need set up the refrigeration demand of heater in order to increase the walk-in at the walk-in to improve the condition of compressor 30's turn-on rate, whether this application embodiment satisfies the condition of predetermineeing through judging that whether the shut down of ambient temperature and compressor 30 is long, forces to open compressor 30 after satisfying the condition of predetermineeing, makes refrigerator 100 when lower ambient temperature, also can refrigerate, and then can make the freezer satisfy cold volume demand. In addition, the control method of the embodiment of the application does not need to arrange a heater in the refrigerating chamber, so that devices are reduced, and the cost is reduced.

It should be noted that, the compressor 30 and the fan 20 need to be opened simultaneously, because the demand cold volume of the storage compartment is less than the demand cold volume of the freezer, when the freezer is short of cold volume, if the fan 20 still opens after the compressor 30 stops, the uneven condition of cold volume distribution can be aggravated, and when the compressor 30 is opened again after a period of time, the fan 20 is difficult to be opened again, so that the temperature gradient of the freezer is pulled to be very large, and further the freezer can not reach the target temperature. Therefore, the embodiment of the present application can avoid the situation that the target temperature of the freezing chamber cannot be reached by controlling the compressor 30 and the fan 20 to be simultaneously turned on.

In addition, in some embodiments, the fan 20 needs to operate for at least 30 seconds after being started, because when the ambient temperature is 0 ℃ or even below 0 ℃, the refrigeration sensor arranged in the refrigeration space may be always lower than the set shutdown point temperature T1, at this time, the fan 20 may not be effectively turned on, the refrigeration chamber does not need any more refrigeration at this time, and the fan 20 is not turned on, which meets the refrigeration requirement. However, the problem of large temperature gradient of the freezing chamber also occurs in the verification process, so that through further verification of a large number of experiments, the temperature gradient of the freezing chamber can be obviously improved after the fan 20 is turned on for 30 seconds. And the starting time is short, the wind pressure formed by the fan 20 is not enough to send excessive cold energy to the refrigerating chamber, so the temperature of the refrigerating chamber is basically unchanged. It should be noted that, the operation of the fan 20 for at least 30 seconds after being started is an example, and should not be construed as a limitation thereto, and how much time the fan 20 operates after being started needs to be set according to an actual situation, which is not specifically limited herein.

In some embodiments, the compressor 30 is an inverter compressor, and when the compressor 30 is turned on, the compressor 30 may be controlled to operate at a preset rotation speed according to the ambient temperature; the environment temperature range is divided into a plurality of temperature grades in advance, each temperature grade has a corresponding rotating speed, and the rotating speed is in direct proportion to the environment temperature. I.e., the higher the ambient temperature, the greater the speed at which the compressor 30 is turned on. When the ambient temperature is high, the compressor 30 operates at a high rotational speed, so that the refrigerator 100 can be rapidly cooled to prevent the stored goods from being damaged. When the ambient temperature is low, the compressor 30 operates at a low rotational speed, so that the temperature can be accurately controlled, and refrigeration waste is avoided.

In other embodiments, the rotation speed of the compressor 30 is gradually decreased after the compressor 30 is controlled to operate at the preset rotation speed for the first preset time. That is, the compressor 30 is controlled to operate at the highest speed for a period of time, so that the refrigerator 100 can be rapidly cooled, the temperatures of the storage space 120 and the freezing space 110 are both decreased, and then the rotational speed of the compressor 30 is controlled to decrease gradually, so that the temperatures of the storage space 120 and the freezing space 110 are stabilized, and thus, the power consumption can be reduced.

In some embodiments, the fan 20 is a variable frequency fan 20, and the rotation speed of the fan 20 is gradually reduced after the fan 20 is controlled to operate at the first rotation speed for a fifth preset time. Controlling the fan 20 to operate at the maximum speed for a period of time may rapidly cool the storage space 120, so that the temperature of the storage space 120 is decreased. And then the rotating speed of the fan 20 is controlled to be gradually reduced, so that the energy consumption can be reduced.

104. And if the current temperature of the storage space is less than the temperature threshold, controlling the fan to stop.

The current temperature of the storage space 120 is obtained, and whether the current temperature is less than the temperature threshold value is judged, so as to judge whether the storage space 120 meets the cold requirement.

For example, if the current temperature of the storage space 120 is less than the temperature threshold, which indicates that the storage space 120 has satisfied the cooling requirement, the fan 20 is controlled to stop. If the current temperature of the storage space 120 is greater than or equal to the temperature threshold, it indicates that the storage space 120 does not meet the cooling requirement, and the fan 20 is controlled to continue to operate.

In some embodiments, the temperature threshold is set to 0 ℃, so that the freezing condition caused by zero crossing of the refrigerating temperature when the ambient temperature is close to 0 ℃ can be prevented, because the refrigerating space in the control method of the embodiment of the present application no longer has the starting point temperature, but the ambient temperature is close to 0 ℃ in the steady stage as the compressor 30 starts refrigerating, the temperature of the refrigerating space is substantially the same as the ambient temperature, and finally the integrated average temperature of the refrigerating space may zero crossing to cause freezing in the refrigerating space if the stopping point temperature is lower than 0 ℃. For example, it is experimentally verified that in the test verification of 5 ℃ ambient temperature, the stop point of the fan 20 is initially set to-1.5 ℃, and as a result, the average refrigerating temperature reaches about-1 ℃, and after the stop point of the fan 20 is adjusted to 0 ℃, the average temperature of all three refrigerators 100 is above 0.2 ℃. It should be noted that the specific setting of the temperature threshold needs to be set according to different refrigerators 100 and different environments and practical situations, and is not limited in particular here.

105. And controlling the compressor to stop after the preset time.

When the fan 20 is stopped, the compressor 30 is operated for a predetermined time and then stopped.

In some embodiments, the refrigerator 100 includes a second timer connected to the processor 40, the second timer being used to time the operation time of the compressor 30 and transmit the operation time of the compressor 30 to the processor 40.

For example, the processor 40 obtains the operation time of the compressor 30 through a second timer, and controls the compressor 30 to stop if the operation time of the compressor 30 reaches a second preset time. Wherein, in some embodiments, the second predetermined time is less than a shutdown time of the compressor 30. The specific requirements are set according to actual conditions.

It will be appreciated that when the refrigerator 100 is first turned on or first energized after defrosting, the operating time of the compressor 30 may be extended, and in some embodiments, the operating time of the compressor 30 is at least 40 minutes. It should be noted that the specific second preset time may be described according to actual situations, and is not specifically limited herein.

It should be noted that, it is necessary to determine whether the compressor 30 meets the shutdown condition after the blower 20 is shut down, because if the compressor 30 meets the shutdown condition, the compressor is immediately shut down, and the blower 20 continues to be turned on, which may result in a problem of insufficient cooling capacity of the freezing chamber. If the blower 20 and the compressor 30 are shut down together, if a large amount of stored goods are put into the refrigerating space, the refrigerating space cannot be rapidly warmed. If the compressor 30 continues to operate after the blower 20 is stopped, the change of the load can be better adapted, if the temperature of the air circulating to the refrigeration sensor is changed when the storage of the refrigerated space or the freezing space 110 is increased, the cooling time of the refrigerated space is prolonged, the on-time rate of the compressor 30 is increased, and even if the load of the refrigerated space is increased, the freezing space 110 is pulled to a lower temperature in a short period of time without negative effects.

The refrigerator 100 further includes a door disposed at a front side of the refrigerator body 10, so that a user can open or close the storage space 120 and the freezing space 110, and the stop of the compressor 30 can be determined according to other conditions after a preset time, please refer to fig. 3, where fig. 3 is a schematic diagram of a first flow for controlling the stop of the compressor in the control method shown in fig. 2. Controlling the compressor 30 to stop after the preset time further includes the following processes:

201. the opening times of the door of the freezing space is obtained.

The number of times the door of the freezing space 110 is opened within a preset time is acquired.

202. And when the opening times are larger than a preset time threshold value, acquiring the running time of the compressor.

203. And if the running time of the compressor reaches a third preset time, controlling the compressor to stop, wherein the third preset time is greater than the second preset time.

When the door of the freezing space 110 is opened a greater number of times within a preset time, the temperature of the freezing space 110 can be ensured by extending the operation time of the compressor 30.

Referring to fig. 4, fig. 4 is a schematic diagram illustrating a second flow of controlling the compressor to stop in the control method shown in fig. 2. Controlling the compressor 30 to stop after the preset time further includes the steps of:

301. the remaining storage space of the refrigerated space is accessed.

In some embodiments, the items already stored in the refrigerated space 110 are acquired by a weight sensor and the remaining storage space 120 of the refrigerated space 110 is calculated by the processor 40.

In other embodiments, the remaining storage space 120 of the refrigerated space 110 is tested directly by an infrared scanner.

It is understood that the specific manner of acquiring the remaining storage space 120 of the freezing space 110 is not particularly limited herein and may be set according to practical circumstances.

302. And when the residual storage space is smaller than the preset storage space value, acquiring the running time of the compressor.

When the remaining storage space 120 is less than the predetermined storage space 120 value, indicating that there is too much storage in the freezer space 110, it is desirable to provide increased cooling to the freezer space 110.

303. And if the running time of the compressor reaches a fourth preset time, controlling the compressor to stop, wherein the fourth preset time is greater than the second preset time.

By controlling the operation time of the compressor 30 to be extended when the remaining storage space 120 is smaller than the preset storage space 120 value, that is, by controlling the fourth preset time to be longer than the second preset time, it is possible to ensure that the temperature of the freezing chamber reaches the target temperature.

The refrigerator 100 further includes an evaporator, and the freezing space 110 includes a side wall opposite to the door, and the evaporator is disposed on the side wall of the freezing space 110. By arranging the evaporator on the side wall, the refrigerator 100 of the embodiment of the present application may not be provided with an air door, that is, after the fan 20 is stopped, when the compressor 30 continues to refrigerate, the cold energy of the freezing space 110 is not delivered to the refrigerating space due to the sinking of the cold air, thereby ensuring the temperature required by the freezing space 110.

According to the embodiment of the application, the compressor 30 and the fan 20 are controlled to start refrigeration according to the ambient temperature and the shutdown time of the compressor 30, the fan 20 is closed after the storage space 120 reaches the shutdown point, the compressor 30 is controlled to operate for the preset time after the fan 20 is closed, the compressor 30 is enabled to refrigerate the freezing space 110 independently, and then the temperature of the freezing space 110 can be reduced, so that the target temperature of the freezing space 110 can be reached when the ambient temperature is lower, an auxiliary heater and an air door are not needed to be used in the embodiment of the application, devices are reduced, and the cost is saved.

Referring to fig. 5 to 7, fig. 5 is a diagram illustrating the experimental verification that the freezing space reaches the target temperature when the ambient temperature is 10 ℃ and the freezing space is not loaded in the control method shown in fig. 2. Fig. 6 is a diagram illustrating experimental verification that the freezing space reaches the target temperature when the ambient temperature is 10 ℃ and the freezing space is unloaded in the control method illustrated in fig. 2. Fig. 7 is a diagram illustrating experimental verification that the freezing space reaches the target temperature when the ambient temperature is 5 ℃ and the load is not placed on the freezing space in the control method illustrated in fig. 2. It can be seen that when the ambient temperature is 10 c and the refrigerated space 110 is unloaded, the average temperature of the refrigerated space 110 is-22.3 c over a period of time. When the environment temperature is 10 ℃ and the freezing space 110 is loaded, even if the freezing space 110 is placed in the hottest load bag, the maximum temperature of the freezing space is below 18 ℃ below zero, and the test requirement of the freezing space is met. When the ambient temperature is 5 ℃ and no load is placed in the freezing space 110, the three-point integral mean value of the freezing no-load can be pulled down to about-18 ℃, and the refrigerating temperature can be ensured not to exceed 0. Therefore, experiments verify that the control method of the refrigerator provided by the embodiment of the application can ensure that the temperature of the refrigerating space and the temperature of the freezing space both meet the target temperature when the ambient temperature is low, and the refrigerator does not need to be provided with an air door and a heater, so that devices are further reduced, and the cost is saved.
