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 is a partial structure of a system architecture to which the embodiment of the present invention is applied. Referring to fig. 1, the system architecture may be a refrigerator 10, including a compensation heating wire 100, a compressor 200, a refrigerating temperature sensor 300, a first pick 400, a second pick 500 and a defrosting sensor 600.
The refrigerator has no quick-freezing function, the gear is controlled by a cold-storage potentiometer, the operation of the compressor 200 is controlled by the temperature of the cold-storage chamber, the operation of the compressor 200 is controlled by the cold-storage temperature-sensing sensor 300 to sense the cold-storage temperature, the temperature of the variable-temperature chamber is controlled by the first shifting sheet 400, and the temperature of the freezing chamber is controlled by the second shifting sheet 500. As the freezing chamber has no temperature-sensing sensor, the temperature rise of the freezing chamber can not be sensed effectively, namely, the hot articles put into the refrigerator when the user uses the refrigerator can not be sensed, at the moment, the defrosting sensor 600 fixed on the fin evaporator of the refrigerator can be used, the general function of the defrosting sensor 600 is sensing the temperature when defrosting, and when a certain temperature is reached, the defrosting function is quitted. In which the compensating heating wire 100 may be located in a refrigerator liner diagram as shown in fig. 2, the refrigerating temperature sensing sensor 300, the first paddle 400 and the second paddle 500 may be located in a refrigerator assembly diagram as shown in fig. 3, and the frost sensor 600 may be located in a freezer evaporator diagram as shown in fig. 4.
Based on the above description, fig. 5 exemplarily shows a flow of a refrigerator temperature control method according to an embodiment of the present invention, where the flow may be executed by a refrigerator temperature control device, and the device may be located in the refrigerator 10 or the refrigerator 10.
As shown in fig. 5, the process specifically includes:
step 501, periodically acquiring the temperature acquired by a defrosting sensor of the refrigerator.
The temperature collected by the defrosting sensor of the refrigerator can be periodically acquired according to a preset period, and the preset period can be set according to experience, for example, the preset period can be set as the period collected by the defrosting sensor.
Step 502, when it is determined that the temperature collected by the defrosting sensor is greater than a first threshold and less than a second threshold, controlling a refrigeration compensation heating wire to operate according to a preset heating proportion, and controlling the refrigerator to work according to the rotating speed of a compressor of the refrigerator and the temperature collected by the defrosting sensor.
In the embodiment of the present invention, the preset heating ratio of the first threshold and the second threshold may be set empirically, for example, the first threshold and the second threshold may be set based on the temperature collected by the defrosting sensor during normal operation, and if the temperature collected by the defrosting sensor during normal operation is T1C, the first threshold value can be T2DEG C, the second threshold value can be T3C, etc., T1Less than T2Less than T3The setting here is mainly done empirically. Corresponding to a few degrees increase in the temperature picked up by the defrost sensor after a preset period of time of insertion of the hot article.
When the temperature acquired by the defrosting sensor is determined to be greater than the second threshold value, the temperature is indicated to be that the freezing evaporator is blocked, the temperature is remarkably increased, and the defrosting treatment of the machine core is required, so that the refrigerator needs to be protected by defrosting.
When the refrigerator is controlled to work according to the rotating speed of the compressor of the refrigerator and the temperature collected by the defrosting sensor, the running rotating speed of the compressor of the refrigerator can be specifically adjusted according to the preset adjusting times, and the refrigerator works normally when the temperature collected by the defrosting sensor is determined to be smaller than the first temperature threshold value. The preset adjusting times and the first temperature threshold value can be set according to experience. For example, the first temperature threshold may be a temperature collected by a defrost sensor during normal operation.
As an implementation manner, each adjustment may correspond to a preset defrosting temperature threshold, where the preset defrosting temperature threshold is any one of the temperature collected by the defrosting sensor between the first threshold and the second threshold and the temperature before the first temperature threshold. Adjusting the running rotating speed of a compressor of the refrigerator according to the preset adjusting times, judging whether the temperature acquired by the defrosting sensor is smaller than a preset defrosting threshold corresponding to the current adjustment after the running rotating speed of the compressor of the refrigerator is adjusted each time, if so, performing next adjustment until the temperature acquired by the defrosting sensor is smaller than a first temperature threshold, and controlling the normal operation of the ice making box, otherwise, continuously controlling the compressor of the refrigerator to continue running according to the running rotating speed of the current adjustment. The operation speed of the compressor of the refrigerator adjusted every day and the preset defrosting threshold adjusted every day may be as shown in table 1.
TABLE 1
Number of times of adjustment Running speed of compressor Presetting defrosting threshold
1 Compressor running speed 1 Presetting defrosting threshold value 1
2 Compressor running speed 2 Presetting defrosting threshold 2
3 Compressor running speed 3 Presetting defrosting threshold value 3
… … …
That is to say, during each adjustment, whether the temperature acquired by the defrosting sensor is smaller than the preset defrosting threshold corresponding to the adjustment is compared after the adjustment, and the adjustment in the next step is performed only after the condition is met. It should be noted that if the preset adjustment frequency is 1, it indicates that only one adjustment is performed, and at this time, the preset defrosting threshold corresponding to the adjustment is the first temperature threshold, and when the condition is met, the refrigerator can be controlled to normally operate. If the adjustment is carried out for a plurality of times, the running rotating speed of each adjustment can be reduced in an equal proportion or can be a fixed value set according to experience. The corresponding preset defrosting threshold value can be reduced in equal proportion or can be a fixed value set according to experience. When the adjustment is carried out for a plurality of times, the preset defrosting threshold value corresponding to the last adjustment is the first temperature threshold value.
It should be noted that before the next adjustment, it is also necessary to determine whether the operation time of the compressor of the refrigerator is greater than a time threshold, if so, the refrigerator is controlled to normally operate, and if not, the next adjustment is performed.
In order to better explain the embodiment of the present invention, the flow of temperature control of the refrigerator will be described below in a specific implementation scenario. In the embodiment of the present invention, the preset adjustment is 4 at this time. The rotation speed of the compressor is decreased in an equal proportion, and the preset defrosting threshold value is adjusted to be decreased in an equal proportion every time.
As shown in fig. 6, the process specifically includes:
step 601, the refrigerator works normally.

In step 607, whether the continuous operation time of the compressor is greater than the time threshold value is determined, if yes, the step 601 is executed, otherwise, the step 608 is executed.
And 608, adjusting for the second time to adjust the running rotating speed of the compressor to the second rotating speed.
In step 609, whether the temperature collected by the defrosting sensor is smaller than a second preset defrosting threshold value is judged, if yes, the step 610 is executed, and if not, the step 608 is executed.
In step 610, if the continuous operation time of the compressor is greater than the time threshold, the process proceeds to step 601, otherwise, the process proceeds to step 611.
And 611, adjusting for the third time to adjust the running rotating speed of the compressor to the third rotating speed.
In step 612, whether the temperature collected by the defrosting sensor is less than a third preset defrosting threshold value is judged, if yes, the step 613 is executed, and otherwise, the step 611 is executed.
Step 613, judging whether the continuous running time of the compressor is greater than a time threshold, if so, turning to step 601, otherwise, turning to step 614.
And 614, adjusting the running rotating speed of the compressor to a fourth rotating speed for the fourth time.
And step 615, judging whether the temperature collected by the defrosting sensor is smaller than a first temperature threshold, if so, turning to the step 601, and otherwise, turning to the step 616.
In step 616, if the continuous operation time of the compressor is greater than the time threshold, the process proceeds to step 601, otherwise, the process proceeds to step 614.
The specific implementation of the above process has been described in the above embodiments, and is not described herein again.
