Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 schematically shows a system architecture to which an embodiment of the present invention is applicable, where the system architecture may be a refrigerator 100, and the refrigerator 100 may include an environment sensor 110, a controller 120, a temperature sensor 130, a compressor 140, and a fan 150.
The environment sensor 110 is used to collect the ambient temperature and humidity of the refrigerator 100 and transmit the collected data to the controller 120.
The temperature sensor 130 is used to collect an actual temperature in each compartment of the refrigerator 100 and transmit the actual temperature to the controller 120.
The controller 120 may control the rotational speeds of the compressor 140 and the fan 150 of the refrigerator 100 according to the ambient temperature and humidity and the actual temperature in each compartment.
Based on the above description, fig. 2 shows in detail a flow of a method for controlling intelligent operation of a refrigerator according to an embodiment of the present invention, where the flow may be executed by an apparatus for controlling intelligent operation of a refrigerator, and the apparatus may be located in the controller 120 shown in fig. 1, or may be the controller 120.
As shown in fig. 2, the process specifically includes:
The environment temperature and humidity of the refrigerator, namely the environment temperature and the environment humidity can be collected through the environment temperature sensor and the environment humidity sensor.
The corresponding relation between the environment temperature and humidity and the rotating speed of the compressor and the rotating speed of the fan can be preset, and different environment temperatures and humidities can correspond to different rotating speeds of the compressor and the fan. It may thus be preliminarily determined that the compressor may be operated at a first initial rotational speed and the fan may be operated at a second initial rotational speed. For example: the compressor speed is determined to be r1 and the fan speed is determined to be r 1'.
When the compressor and the fan of the refrigerator are controlled according to the temperature difference between the actual temperature and the set temperature in each compartment, the specific method may be as follows:
and determining whether the temperature difference value between the actual temperature and the set temperature in each chamber is smaller than a preset threshold value, if so, controlling the rotating speeds of a compressor and a fan of the refrigerator to be unchanged and continuing for a second preset time, and then, determining whether the actual temperature and the set temperature in each chamber of the refrigerator are consistent, if not, continuing to determine whether the temperature difference value between the actual temperature and the set temperature in each chamber is smaller than the preset threshold value until the actual temperature and the set temperature in each chamber of the refrigerator are consistent.
Further, if the temperature difference between the actual temperature and the set temperature in each compartment is not less than the preset threshold, controlling the compressor to operate at the first compressor rotation speed and controlling the fan to operate at the first fan rotation speed, and after operating for a second preset time, judging whether the actual temperature in each compartment of the refrigerator is consistent with the set temperature, if not, continuously determining whether the temperature difference between the actual temperature and the set temperature in each compartment is less than the preset threshold until the actual temperature in each compartment of the refrigerator is determined to be consistent with the set temperature.
The first preset time, the set temperature, the first low rotation speed, the second low rotation speed, the preset threshold, the second preset time, the first compressor rotation speed and the first fan rotation speed may be set according to a test or experience.
For example, when the compressor rotation speed r1 and the fan rotation speed r1 'are operated for a specified time t1, the box body automatically detects and judges the actual temperature and the set temperature of each compartment, if the actual temperature and the set temperature are consistent, the fact that a user does not perform other operations and the box body operates stably is indicated, the rotation speeds of the compressor and the fan are automatically reduced to the preset minimum rotation speeds r2 and r2' at the ambient temperature; if the difference is not satisfied, the operation is carried out again after the compressor rotating speed r1 and the fan rotating speed r1' continue to operate for the specified time T1, namely the compressor and the fan rotating speeds automatically drop to the preset minimum rotating speed r2/r2' under the environment temperature, if the difference is not satisfied, the judgment is carried out according to the difference delta T between the actual temperature in the box and the set temperature, if the difference is less than the specified value T1, the operation is carried out continuously with the compressor rotating speed r1 and the fan rotating speed r1', if the difference is more than or equal to the specified value T1, the operation is carried out according to the rules of the compressor rotating speed r0 and the fan rotating speed r0', the detection is carried out again after the specified time T2, if the corresponding compressor and fan rotating speeds automatically drop to the preset minimum rotating speed r2/r2' under the environment temperature, if the corresponding compressor and the operation is not satisfied, the operation is carried out continuously until the corresponding rotation is satisfied.
Further, after the compressor is controlled to operate at the first low rotation speed and the fan is controlled to operate at the second low rotation speed, the operation rate of the refrigerator after the refrigerator continues to operate for a third preset time can be obtained, whether the operation rate of the refrigerator is greater than the operation rate threshold value or not is determined, if yes, the compressor is controlled to increase the first preset rotation speed to operate and the fan is controlled to increase the second preset rotation speed to operate until the operation rate of the refrigerator is smaller than or equal to the operation rate threshold value. The third preset time, the threshold of the turn-on rate, the first preset rotation speed and the second preset rotation speed may be set according to tests or experience.
That is, after the minimum compressor rotation speed r2 and the minimum fan rotation speed r2' are operated for the time t2, the start-up rate is detected again, if the minimum compressor rotation speed r2 and the minimum fan rotation speed r2' are greater than the specified start-up rate, the compressor rotation speed and the fan rotation speed are increased by the specified rotation speeds n and n ' until the start-up rate requirements are met, and the operation is performed normally according to the final debugging rotation speed.
In the above process, when it is determined that the rotation speed of the compressor of the refrigerator is less than the first initial rotation speed, the defrosting interval time of the refrigerator may be set to the maximum preset interval time. That is, when the compressor rotation speed is less than the initial compressor rotation speed r1, the defrosting interval time is performed for the maximum interval time N value.
The embodiment shows that the environment temperature and the environment humidity of the refrigerator are obtained, the compressor of the refrigerator is determined to operate at a first initial rotating speed and the fan is determined to operate at a second initial rotating speed according to the environment temperature and the environment humidity, whether the actual temperature in each chamber of the refrigerator is consistent with the set temperature or not is judged after the refrigerator is operated for the first preset time, if not, whether the actual temperature in each chamber of the refrigerator is consistent with the set temperature or not is judged after the refrigerator is continuously operated for the first preset time, if not, the compressor and the fan of the refrigerator are controlled according to the temperature difference value between the actual temperature in each chamber and the set temperature, and the compressor is controlled to operate at the first low rotating speed and the fan is controlled to operate at the second low rotating speed until the actual temperature in each chamber of the refrigerator is consistent with the set temperature. The compressor and the fan of the refrigerator are gradually adjusted by comparing the actual temperature and the set temperature in each chamber of the refrigerator after the refrigerator runs for a period of time, so that the noise of the refrigerator under a user use mode without a newly added load can be reduced, the power consumption of the refrigerator is reduced, and the user experience is improved.
