In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.
The existing side-by-side combination refrigerator is only provided with one evaporator and one fan, and the evaporator and the fan are both arranged in a freezing chamber. The temperature control of the refrigerating chamber depends on the air door to control the air supply. The refrigerating return air inlet is generally positioned at the bottommost part of the refrigerating chamber and communicated with the freezing chamber. When the refrigerating chamber and the freezing chamber are not refrigerated, the compressor is stopped, the fan is stopped, and the air door is closed. At the moment, no forced air circulation exists in the refrigerator chamber, and natural convection heat exchange is realized by wind. However, because the refrigerating chamber is communicated with the freezing chamber through the air return opening, cold air in the freezing chamber can flow backwards into the refrigerating chamber, so that the refrigerating chamber freezes.
Therefore, in order to solve the above problems, the present application proposes a metal oxide thin film transistor, a display panel and a method for manufacturing the same. The present application will be further described with reference to the accompanying drawings and embodiments.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a control method of a refrigerator according to an embodiment of the present application. The embodiment of the application provides a control method of a refrigerator, the control method is applied to the refrigerator, the refrigerator comprises a freezing chamber and a refrigerating chamber, a refrigerating return air inlet is arranged between the refrigerating chamber and the freezing chamber, the freezing chamber is provided with a freezing fan and an evaporator, and the control method comprises the following processes:
101. the refrigerating state of the freezing chamber and the refrigerating state of the refrigerating chamber are obtained.
The refrigerating state of the freezing chamber and the refrigerating state of the refrigerating chamber are detected. The refrigerating state of the refrigerating chamber comprises a refrigerating state, a non-refrigerating state, a refrigeration demand sending state and the like, and the refrigerating state of the refrigerating chamber comprises a refrigerating state, a non-refrigerating state, a refrigeration demand sending state and the like.
It is understood that the cooling state can be judged according to the states of the damper, the freezing fan and the compressor. For example, when the damper, the freezing fan and the compressor are all in the off state, the freezing chamber and the refrigerating chamber are all in the uncooled state. When the air door, the freezing fan and the compressor are all in operation states, the freezing chamber and the refrigerating chamber are all in a refrigerating state. When the compressor is stopped, the freezing fan is in operation, and the air door is opened, the freezing chamber is in a non-refrigeration state, and the refrigerating chamber is in a refrigeration state. When the compressor is in operation, the freezing fan is in operation, the air door is closed, the freezing chamber is in a refrigerating state, and the refrigerating chamber is in a non-refrigerating state.
102. And if the freezing chamber and the refrigerating chamber are in a non-refrigeration state and the freezing fan is in a stop state, obtaining the stop time of the freezing fan.
And when the freezing chamber and the refrigerating chamber are determined to be in a refrigerating state, the current air door, the freezing fan and the compressor are in a stop state, and the stop time of the freezing fan is obtained.
Wherein, the stop time of the freezing fan can be obtained by applying a timer.
It should be noted that, the refrigerator further includes a defrosting heater, and before the stop time of the freezing fan is acquired, the control method further includes: judging whether the refrigerator meets defrosting conditions or not; if so, controlling the refrigerating fan not to operate and controlling the defrosting heater to be in a working state; and if not, acquiring the stop time of the refrigerating fan. Namely, whether the refrigerator is in defrosting or not is judged in advance, the situation that the freezing fan is forcibly started in defrosting can be avoided, and therefore control of the freezing fan can be more reasonable.
103. And if the stop time is determined to exceed the threshold value, controlling the refrigerating fan to be started.
And if the stop time is determined to exceed the threshold value, controlling the freezing fan to be started and operating at the first rotating speed. Wherein, in some embodiments, if the stop time is within 10 minutes, the freezing fan is controlled to operate at 1200 r.
It should be noted that the threshold may be set according to actual application conditions or historical data, may be updated according to the ambient temperature, or may be modified by the client.
Fig. 2 is a schematic diagram illustrating a first flowchart of determining a threshold in the control method shown in fig. 1, as shown in fig. 2 to 4. Fig. 3 is a second flowchart illustrating the determination of the threshold in the control method shown in fig. 1. Fig. 4 is a third flowchart illustrating the determination of the threshold in the control method shown in fig. 1.
In some embodiments, as shown in fig. 2, after acquiring the stop time of the freezing fan, the control method further includes the steps of:
201. and acquiring the current ambient temperature.
202. And if the ambient temperature is in a first preset range, determining the threshold value as a first threshold value.
203. And if the ambient temperature is in a second preset range, determining that the threshold is a second threshold, wherein the maximum value of the first preset range is smaller than the minimum value of the second preset range, and the first threshold is larger than the second threshold.
The stop time of the freezing fan is determined by determining the threshold value according to the current environment temperature, namely the stop time of the freezing fan is shorter when the environment temperature is lower, so that the icing condition at low temperature is avoided to be more serious, and the icing condition at the refrigerating return air inlet can be more accurately prevented.
In some embodiments, as shown in fig. 3, after the stop time of the freezing fan is acquired, the control method further includes the steps of:
301. a temperature difference between the current temperature of the freezer compartment and the temperature of the refrigerator compartment is obtained.
302. And if the temperature difference is within the first preset temperature difference range, determining the threshold value as a third threshold value.
303. And if the temperature difference is within a second preset temperature difference range, determining that the threshold is a fourth threshold, wherein the maximum value of the first preset temperature difference range is smaller than the minimum value of the second preset temperature difference range, and the third threshold is larger than the fourth threshold.
The stop time of the freezing fan is determined through the temperature difference between the current temperature of the freezing chamber and the temperature of the refrigerating chamber, namely, when the temperature difference is larger, the stop time of the freezing fan is shorter, so that the situation that the freezing condition is more serious due to the fact that cold air of the freezing chamber enters the freezing chamber more and more when the temperature difference is too large is avoided, and the freezing condition at the refrigerating return air inlet can be more accurately prevented.
In some embodiments, as shown in fig. 4, after the stop time of the freezing fan is acquired, the control method further includes the steps of:
401. the temperature difference between the current temperature of the freezing chamber and the current temperature of the refrigerating chamber is acquired, and the current ambient temperature is acquired.
402. And if the environment temperature is in a first preset range and the temperature difference is in the first preset temperature difference range, determining that the threshold is a fifth threshold.
403. And if the ambient temperature is in the first preset range and the temperature difference is in the second preset temperature difference range, determining that the threshold is a sixth threshold.
404. And if the environment temperature is in a second preset range and the temperature difference is in a first preset temperature difference range, determining that the threshold is a seventh threshold.
405. If the environment temperature is in a second preset range and the temperature difference is in the second preset temperature difference range, determining the threshold value as an eighth threshold value; the maximum value of the first preset range is smaller than the minimum value of the second preset range, the maximum value of the first preset temperature difference range is smaller than the minimum value of the second preset temperature difference range, and the fifth threshold, the sixth threshold, the seventh threshold and the eighth threshold are all unequal.
The stop time of the freezing fan is determined by combining the temperature difference between the current freezing chamber and the refrigerating chamber and the current environment temperature, so that the stop time of the freezing fan is more accurate, the freezing-free air return port can be ensured, and the energy consumption can be reduced.
In other embodiments, the threshold may be adaptively adjusted according to different temperature changes in the year and different temperature changes in the day, so that the threshold may be more suitable for the current application.
It can be understood that the rotating speed of the freezing fan can be specifically set and adjusted according to the model and the ambient temperature of the actual fan and the stop time of the freezing fan, and the freezing fan is not described herein any more, and only needs to meet the condition of preventing the freezing of the cold storage air return inlet.
In other embodiments, if the stop time is determined to exceed the second threshold, controlling the refrigeration fan to operate at the first speed for a first period of time; controlling the freezing fan to operate at the first rotating speed for a second time period after the freezing fan operates for the first time period; wherein the second duration is greater than the first duration. That is, when the residence time of both the freezing fan and the compressor is too long, in order to make the cold air in the freezing chamber form negative pressure more quickly, the freezing fan can be started to operate at a higher rotating speed in the second time range, so as to prevent the cold air from flowing into the refrigerating chamber from the freezing chamber. And after the freezing fan operates for the first time, the freezing fan is switched to operate at a lower speed, so that cold air can be prevented from flowing into the refrigerating chamber, and energy conservation and consumption reduction can be realized.
According to the control method of the refrigerator, the running state of the freezing fan is controlled according to the refrigerating state of the freezing chamber, the refrigerating state of the refrigerating chamber and the stopping time of the freezing fan, when the freezing chamber and the refrigerating chamber are in a non-refrigerating state, the stopping time of the freezing fan is obtained, and when the stopping time reaches a threshold value, the freezing fan is controlled to be started.

501. and if the stop time is determined to exceed the threshold value, acquiring the current ambient temperature.
And if the stop time is determined to exceed the threshold value, acquiring the ambient temperature of the refrigerator through the temperature sensor.
502. And if the ambient temperature is lower than the preset temperature, controlling the freezing fan to be started at a third rotating speed.
It can be understood that the preset temperature can be set according to practical application conditions or historical data, which is exemplary, in some embodiments, the temperature range set by the refrigerating chamber is 2 ℃ to 8 ℃, and further the preset temperature is set to be less than 8 ℃, because when the ambient temperature is higher, the refrigerating chamber or the freezing chamber can be started for refrigeration, and further the freezing fan can be started, therefore, when the preset temperature is set to be less than the maximum temperature range set by the refrigerating chamber, better temperature control can be connected, the condition that the ambient temperature is too low is avoided, and the freezing chamber are not refrigerated, the refrigerating return air inlet is frozen, namely, under the condition that the refrigerating chamber and the freezing chamber are not refrigerated, as long as the ambient temperature is less than the maximum temperature range set by the refrigerating chamber, the fan is started forcibly, so as to prevent the freezing condition from occurring at the refrigerating return air inlet.
503. If the environmental temperature is higher than the preset temperature, controlling the refrigerating fan to be started at a fourth rotating speed; the fourth rotational speed is greater than the third rotational speed.
When the freezing fan is started, if the temperature is higher than the preset temperature, the freezing fan needs to operate at a higher rotating speed.

and if the freezing chamber and the refrigerating chamber are both in the state of sending refrigeration demands, determining that the freezing fan is in a stop state, and acquiring the current environment temperature.
