Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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.
It can be understood that, after the compressor is started, according to the existing control rule, the fan will start to rotate, but at this time, the temperature in the refrigerator compartment is the same as the ambient temperature, the whole refrigeration system is still in an unbalanced state, the pressure at the two sides of the compressor suction and exhaust can reach 15kg, the refrigerant in the evaporator is in a high-temperature gas state, and the circulation action of the fan accelerates the rapid evaporation of the refrigerant in the evaporator, resulting in the increase of the system pressure.
To solve the problem, an embodiment of the present invention provides a refrigerator control method, which is used for controlling an air-cooled refrigerator, the air-cooled refrigerator includes a refrigerating chamber and a freezing chamber, a compressor and a fan are installed in the freezing chamber, and referring to fig. 2, the method includes the following steps:
step 101: after the refrigerator is powered on, the current environment temperature is detected, and if the current environment temperature is larger than or equal to a first temperature threshold value, the freezing temperature of the freezing chamber is detected.
Step 102: and if the freezing temperature of the freezing chamber is greater than or equal to the second temperature threshold, controlling the compressor to start, and controlling the fan to start after delaying a first time period relative to the compressor.
It is understood that the freezing temperature of the freezing chamber may be acquired by a temperature sensor provided at the freezing chamber.
It can be understood that, because the refrigerator control method provided in this embodiment is a control strategy at a high ambient temperature, the first temperature threshold should be a higher temperature value, and preferably, the value range of the first temperature threshold is 30-38 ℃.
It will be understood that the compressor is only required to be controlled to start when the freezer compartment temperature is greater than or equal to the freezer compartment starting temperature, and therefore the second temperature threshold is actually the freezer compartment starting temperature, and preferably the second temperature threshold ranges from-2 ℃ to 1 ℃.
It can be understood that, in order to reduce the system pressure when the compressor is started in a high-temperature environment, the startup delay time of the fan relative to the compressor is not too short, otherwise, the effect of relieving the pressure cannot be achieved, and meanwhile, since the fan is required to perform cold air circulation after the compressor is cooled, the startup delay time of the fan relative to the compressor is not too long, and preferably, the value range of the first time period is 4min to 8 min.
As can be seen from the above description, in the refrigerator control method provided in this embodiment, after the refrigerator is powered on, the current ambient temperature is detected, and if the current ambient temperature is greater than or equal to the first temperature threshold, the freezing temperature of the freezing chamber is detected; and if the freezing temperature of the freezing chamber is greater than or equal to the second temperature threshold, controlling the compressor to start, and controlling the fan to start after delaying a first time period relative to the compressor. It can be seen that, in the embodiment, the fan is controlled to start up after the compressor is started up for a period of time, so that the system pressure during the start-up of the compressor can be effectively reduced (for a specific reason, see the description in the second paragraph of the specific embodiment), and the refrigerator compressor can be normally started up at a high ambient temperature. In addition, the processing mode of the embodiment can also ensure that the compressor can be normally started in the area with low power grid voltage under the condition of high-load use.

step 103: and detecting the refrigerating temperature of the refrigerating chamber, and if the refrigerating temperature of the refrigerating chamber is greater than or equal to a third temperature threshold value, controlling the air door to start after delaying a second time period relative to the fan.
It can be understood that a refrigerating temperature sensor is installed in the refrigerating chamber, an air door is arranged in an air channel between the refrigerating chamber and the freezing chamber, and after the fan is started, the air door is opened as soon as possible in order to cool the refrigerating chamber as soon as possible, so that the second time period is not too long. Preferably, the value of the second time period ranges from 10s to 30 s.
In the embodiment, the air door is controlled to be started after the fan is started for a period of time, so that the system pressure during the starting of the compressor can be further effectively reduced, and the refrigerator compressor can be normally started at high ambient temperature.
It can be seen that this embodiment adopts the compressor start earlier, and later the fan starts again a period of time, and later the control strategy that the air door started again a period of time, can effectively reduce the load of compressor initial start under the high load condition, reduce compressor operating power, prevent because the compressor thermal protector that the electric current value is too big leads to the overload protection condition to appear.
In a preferred implementation of this embodiment, referring to fig. 4, the method further comprises:
step 104: recording a first working time length of the air door after the air door is started up from the last time and a second working time length of the fan after the fan is started up from the last time; closing the damper when the first length of operation equals a first length of operation threshold; turning off the fan when the second working time is equal to a second working time threshold; for example, the first operating time threshold is 2min, and the second operating time threshold is 4 min.
Correspondingly, recording a first shutdown time length of the air door after the air door is shutdown for the last time and a second shutdown time length of the fan after the fan is shutdown for the last time; opening the damper when the first shutdown duration is equal to a first shutdown duration threshold; when the second shutdown time length is equal to a second shutdown time length threshold value, the fan is turned on; for example, the first shutdown duration threshold is 8min, and the second shutdown duration threshold is 6 min.
The first working duration threshold is smaller than the second working duration threshold, the first shutdown duration threshold is larger than the second shutdown duration threshold, and the sum of the first working duration threshold and the first shutdown duration threshold is equal to the sum of the second working duration threshold and the second shutdown duration threshold.
On the premise of reducing the load pressure of the system, in order to enable the fan and the damper to form a good fit and a good refrigeration effect, preferably, the first operating time length threshold is equal to the second operating time length threshold/2.
From the above description, this embodiment makes fan and air door timesharing control, alternative work when high ambient temperature circular telegram to reduce the system pressure of compressor, prevent that overload protection from appearing in the compressor, guarantee that the compressor can normally start under the high load condition.

d. The air door is closed after being opened for 2min, and the fan is closed after being opened for 4min (T air door is T fan/2).
e. The fan is turned off for 6min and then turned on again, and the air door is turned off for 8min and then turned on again. The on-off period of the air door and the fan is 10 min.
f. The difference between the freezing temperature and T1 is determined to be greater than 20, and the fan and damper are switched to normal control.
g. The refrigerating temperature is lower than the shutdown temperature of the refrigerating chamber, and the air door is closed.
h. The freezing temperature is lower than the shutdown temperature of the freezing chamber, the compressor is shut down, and the fan is shut down.
Therefore, according to the refrigerator control method provided by the embodiment, under a high ambient temperature, the compressor is started firstly, then the fan is started after a period of time, and then the air door is started after a period of time, so that the load of the initial start of the compressor under a high-load condition can be reduced, the running power of the compressor is reduced, and the overload protection condition of the compressor thermal protector caused by an overlarge current value is prevented. In addition, according to the refrigerator control method provided by the embodiment, the fan and the air door are controlled in a time-sharing mode and work alternately, refrigeration is not delayed, and the operation load of the compressor can be reduced, so that the compressor can be started normally under a high-load condition.
