The defrosting method of the existing refrigerator generally triggers the defrosting mode by setting a fixed time interval or according to the temperature of the evaporator. However, this method has some drawbacks, such as that a fixed time interval may not be the optimal defrosting timing, resulting in waste of energy consumption or freezing of condensed water of food in the refrigerator, and misjudgment may occur by triggering the defrosting mode by the evaporator temperature, resulting in a defrosting operation being performed too early or too late, thereby affecting the performance and efficiency of the refrigerator.
Referring to fig. 1, an embodiment of the present invention provides a defrosting dual-mode control method for a refrigerator, the refrigerator including a defrosting sensor, an evaporator, a compressor and a compartment, the defrosting sensor being used for detecting a temperature of the evaporator, the method specifically including:
s101: entering a natural defrosting mode according to the instruction of stopping refrigeration;
and exiting the natural defrosting mode according to the set temperature of the compartment, the detection temperature of the defrosting sensor and the first set defrosting time, or exiting the natural defrosting mode when the defrosting sensor is in a fault state and the duration of the natural defrosting mode reaches the second set defrosting time.
In some embodiments, the exiting the natural defrosting mode according to the set temperature of the compartment, the detected temperature of the defrosting sensor, and the first set defrosting time specifically includes:
when the set temperature of the compartment is greater than the first set temperature and the detection temperature of the defrosting sensor is greater than or equal to the first detection temperature, the natural defrosting mode is exited;
or when the set temperature of the compartment is smaller than or equal to the first set temperature and the detection temperature of the defrosting sensor is larger than or equal to the second detection temperature, the natural defrosting mode is exited;
or when the duration of the natural defrosting mode reaches the first set defrosting time, exiting the natural defrosting mode.
In some embodiments, the first set temperature is 3 ℃, the first detected temperature is 5 ℃, the second detected temperature is 4 ℃, and the first set defrosting time is 60 minutes.
In some embodiments, after the exiting the natural defrosting mode, further comprises: and restarting refrigeration after exiting the natural defrosting mode for one minute.
In some embodiments, the second set defrosting time is 30 minutes.
In this embodiment, when the cooling is finished, a natural defrosting mode is performed, and when the cooling is performed, the fan of the evaporator runs, and the natural defrosting mode is exited according to any one of the following conditions:
condition one: when the set temperature T1 of the compartment is more than 3 ℃, the defrosting sensor temperature T2 is more than or equal to 5 ℃ and exits from naturally defrosting, the fan of the evaporator is stopped, and under the set temperature condition, the maximum time of naturally defrosting is 60 minutes;
condition II: when the set temperature T1 of the compartment is less than or equal to 3 ℃, the defrosting sensor temperature T2 is more than or equal to 4 ℃ and exits from naturally defrosting, the fan of the evaporator is stopped, and under the set temperature condition, the maximum time of naturally defrosting is 60 minutes;
and (3) a third condition: when the defrosting sensor fails, the natural defrosting time is executed according to 30 minutes.
After the natural defrosting is completed (whether the exit temperature is reached or not), the cooling is allowed to start after waiting for 1 minute.
The set temperature T1 of the compartment refers to the set temperature of the probe on/off of the compartment in the refrigerator (the same applies below), the defrosting sensor temperature T2 refers to the evaporator temperature, and whether defrosting is clean or not is detected by the defrosting sensor arranged on the evaporator (the same applies below). The setting temperature T1 of the room in the natural defrosting mode takes 3 ℃ as the intercept point of the interval, because the temperature in the room is lower when the setting temperature of the room is less than or equal to 3 ℃, and the second detection temperature is higher when the setting is higher, the fan starting time of the evaporator is prolonged for a while, so that the energy consumption is increased, and the second temperature in the room is increased. When the set temperature of the compartment is more than 3 ℃, the temperature in the box is higher, and the first detection temperature can be set higher without causing great adverse effects on energy consumption and the temperature in the box. Different defrosting exit temperatures are set in separate temperature control intervals, so that an energy-saving effect is achieved, defrosting is guaranteed to be complete, the working time of a fan of the evaporator can be shortened, and energy consumption is reduced. The higher the defrosting temperature of the defrosting sensor is, the longer the fan of the evaporator needs to be operated, and the higher the energy consumption is.
S102: and entering a shutdown defrosting mode according to the set temperature of the compartment, the actual temperature of the compartment, the detection temperature of the defrosting sensor and the accumulated running time of the compressor.
In some embodiments, the entering the shutdown defrosting mode according to the set temperature of the compartment, the actual temperature of the compartment, the detected temperature of the defrosting sensor and the accumulated running time of the compressor specifically includes:
setting a first condition, wherein the first condition is that the set temperature of the compartment is less than or equal to a second set temperature, the accumulated running time of the compressor reaches a first running time, the second set temperature is 2 ℃, and the first running time is 2 hours;
setting a second condition, wherein the second condition is that the set temperature of the compartment is greater than or equal to a first set temperature, the accumulated running time of the compressor reaches a second running time, the first set temperature is 3 ℃, and the second running time is 4 hours;
setting a third condition, wherein the third condition is that the actual temperature of the compartment is less than or equal to a third detection temperature, and the detection temperature of the defrosting sensor is less than or equal to a fourth detection temperature, the third detection temperature is 10 ℃, and the fourth detection temperature is 8 ℃;
entering a shutdown defrosting mode when only the first condition or the second condition is met;
and when the first condition and the third condition are simultaneously met or the second condition and the third condition are simultaneously met, not entering a shutdown defrosting mode.
In this embodiment, the following is a condition for entering the shutdown defrosting mode, and the determination is performed in order.
Condition one: when the set temperature T1 of the compartment is less than or equal to 2 ℃, the compressor is operated for 2 hours in an accumulated way, and a shutdown defrosting mode is entered.
Condition II: when the set temperature T1 of the compartment is more than or equal to 3 ℃, the compressor is operated for 4 hours in a cumulative way, and a shutdown defrosting mode is entered.
And (3) a third condition: under the premise of the first condition or the second condition, if the actual temperature t1 of the inner chamber of the box is more than 10 ℃ and the defrosting sensor temperature t2 is more than 8 ℃, the shutdown defrosting mode is not started until one of the conditions is not met, namely, the actual temperature t1 of the inner chamber of the box is less than or equal to 10 ℃ or the temperature t2 of all the defrosting sensors is less than or equal to 8 ℃, and the shutdown defrosting mode is started.
This is because when the actual temperature t1 of the compartment in the refrigerator is >10 c and the defrosting sensor temperature t2 is >8 c, the temperatures of the refrigerator compartment and the evaporator are too high, and even if the condition one or the condition two is satisfied, it is not suitable to enter the shutdown defrosting mode.
S103: and exiting the shutdown defrosting mode according to the detection temperature of the defrosting sensor and the third set defrosting time, or exiting the shutdown defrosting mode when the defrosting sensor is in a fault state and the duration of the shutdown defrosting mode reaches the second set defrosting time.
In some embodiments, the exiting the shutdown defrosting mode according to the detected temperature of the defrosting sensor and the third set defrosting time specifically includes:
when the detection temperature of the defrosting sensor is larger than a fifth detection temperature, exiting the shutdown defrosting mode, wherein the fifth detection temperature is 8 ℃;
and when the duration of the shutdown defrosting mode reaches a third set defrosting time, exiting the shutdown defrosting mode, wherein the third set defrosting time is 90 minutes.
In some embodiments, after the exiting the shutdown defrosting mode, further comprises: and restarting refrigerating after exiting the shutdown defrosting mode for one minute, and resetting the accumulated running time of the compressor and restarting timing.
In the embodiment, the fan of the evaporator runs at full speed during the defrosting process, the defrosting sensor temperature t2 is higher than 8 ℃ and exits from the defrosting mode, so that the phenomenon that the fan runs when the temperature of the evaporator is too high to cause waste of excessive energy consumption is avoided; or stopping defrosting time reaches 90 minutes, and outputting a stopping defrosting mode. After stopping defrosting is completed, waiting for 1 minute, and then allowing refrigeration to start, resetting the accumulated starting time of the compressor and restarting timing. When the defrosting sensor fails, the shutdown defrosting time is executed according to 30 minutes.
In sum, the longest time of setting the natural defrosting mode and the shutdown defrosting mode is to prevent the temperature in the box from rising too high due to the fact that defrosting is carried out all the time, the defrosting mode is also directly exited only under the condition that the longest time is met, and the natural defrosting mode or the shutdown defrosting mode can be set more flexibly through double control of time and temperature.
Meanwhile, the defrosting dual-mode control method for the refrigerator disclosed by the embodiment of the invention is more suitable for compartments with the actual temperature in the refrigerator being greater than or equal to 0 ℃ and is not suitable for compartments with the actual temperature in the refrigerator being less than 0 ℃, because the actual temperature in the refrigerator is greater than 0 ℃ due to the defrosting mode for the compartments with the actual temperature in the refrigerator being less than 0 ℃, so that originally frozen objects are not allowed to melt.
