fig. 1 is a schematic structural diagram of a defrosting control device of a refrigerator according to an embodiment of the present application. As shown in fig. 1, the defrosting control apparatus 100 of the refrigerator includes: an evaporation probe 101 of the refrigerator, a box temperature probe 102 and a temperature data processing controller 103.
The temperature data processing controller is respectively connected with the box temperature probe and the evaporation probe; the box temperature probe is used for detecting the box body inventory temperature of the refrigerator and transmitting the box body inventory temperature to the temperature data processing controller; the evaporation probe is used for detecting the evaporation temperature and transmitting the evaporation temperature to the temperature data processing controller; the temperature data processing controller is used for controlling the refrigerator to exit the refrigeration working stage and enter the defrosting working stage when the condition that the temperature difference value obtained by subtracting the evaporation temperature from the storage temperature of the refrigerator body is greater than the preset SET value lasts for a first preset duration in the process that the refrigerator is in the refrigeration working stage.
As shown in fig. 2, the temperature data processing controller collects a temperature value T1 fed back by the evaporation probe and a temperature value T2 fed back by the box temperature probe, and the temperature data processing controller calculates in real time whether a condition that T1-T2 > a SET value is satisfied, wherein the SET value is a defrosting start SET value SET. When the condition is established, the phase of time comparison is entered, namely when the defrosting condition T1-T2 is more than the SET value, the condition must be established within the preset time value of duration, and the condition proves that the frosting amount of the evaporator is excessive, the heat conduction of the refrigerant is influenced, and the system must enter the defrosting phase.
Through two probe refrigerator intelligence defrosting control, replace conventional time interval defrosting control mode, in the embodiment of this application, adopt two temperature sensor probes to gather real-time temperature, through the real-time data that two probes were gathered, calculate statistics and judge whether get into the defrosting process, through reasonable intelligent control logic, control defrosting equipment work, no matter be steam defrosting mode or electric heat defrosting mode, all can realize intelligent defrosting control. Corresponding strain can be made for various environments used by customers: the evaporator can defrost in time when frosting is fast, so that the product faults caused by frost blockage of the product in the using process are avoided; when the evaporator frosts slowly, the defrosting is not controlled to be started any more, and the energy waste is avoided.
In some embodiments, the temperature data processing controller is further configured to: and in the process that the refrigerator is in the refrigeration working phase, when the temperature difference is less than or equal to the preset SET value, or when the temperature difference is greater than the preset SET value and does not last for a first preset duration, controlling the refrigerator to be in the refrigeration working phase continuously.
As shown in FIG. 2, the temperature data processing controller collects whether the condition of calculating the value T1-T2 > SET is satisfied in real time, if the condition is not satisfied, the frosting amount of the evaporator is small, and the continuous cooling state is not influenced. And judging whether the condition that the T1-T2 is more than the SET value lasts for the time specified by the time, entering a defrosting stage if the continuous condition is met, and continuing the cooling state if the continuous condition is not met.
In the embodiment of the application, the condition that T1-T2 is larger than SET value when the product is electrified for the first time is ignored during the logic operation and judgment of the temperature data processing controller, and further the defrosting function is prevented from being started mistakenly when the product is electrified for the first time.
In some embodiments, the temperature data processing controller is further configured to: and in the process that the refrigerator is in the defrosting working stage, acquiring the current evaporation temperature detected by the evaporation probe, and when the current evaporation temperature reaches the preset defrosting ending temperature, controlling the ice making box to exit the defrosting working stage and enter the dripping working stage.

In some embodiments, the defrosting mode of the refrigerator in the defrosting operation stage comprises any one or more of the following modes: defrosting by an electric heating pipe, defrosting by hot gas of a compressor and naturally defrosting by air. And the defrosting control is more flexible through various defrosting modes.
Example two:
fig. 3 is a schematic structural diagram of a defrosting control system of a refrigerator according to an embodiment of the present application. As shown in fig. 3, the defrost control system 300 of the refrigerator includes: a defrosting device 301, a cooling device 302, a dripping device 303 and a defrosting control device of the refrigerator provided as the first embodiment; a temperature data processing controller in the defrosting control device of the refrigerator is respectively connected with the defrosting device, the refrigerating device and the water dripping device.
In some embodiments, the temperature data processing controller is configured to: and when the refrigerator exits the refrigeration working stage and enters the defrosting working stage, closing the refrigeration device and opening the defrosting device. Namely, the temperature data processing controller comprises the functions of controlling the refrigeration and defrosting components, and after the defrosting condition is met, the refrigeration device is closed and the defrosting device is opened.
In some embodiments, the temperature data processing controller is further configured to: and when the refrigerator exits the defrosting working stage and enters the water dropping working stage, closing the defrosting device and opening the water dropping device. Namely, the temperature data processing controller comprises the functions of controlling the water dripping, refrigerating and defrosting components, and after defrosting is finished, the defrosting device is closed, the water dripping device is opened, and the refrigerating device is subsequently opened.
For example, as shown in fig. 4, the defrosting control system of the refrigerator includes components: a box temperature probe 1; an evaporation probe 2; a controller 3; a compressor 4; a first tee 5; a condenser 6; a drying filter 7; a normally open solenoid valve 8; a capillary 9; a second tee 10; an evaporator 11; the solenoid valve 12 is normally closed. As shown in fig. 2 and 4, the specific operation process and specific implementation of the defrosting control system of the refrigerator are as follows:
firstly, the product is initially electrified, the temperature data processing controller 3 processes the temperatures of the box temperature probe 1 and the evaporation probe 2, the operation and judgment of the defrosting operation in the initial electrification are ignored, and the compressor 4 is directly controlled to be started to enter the refrigeration state. The normally closed solenoid valve 12 is closed, and the normally open solenoid valve 8 is open, and the refrigerant cycle compressor 4 → the first three-way 5 (three-way 1) → the condenser 6 → the filter drier 7 → the normally open solenoid valve 8 → the capillary tube 9 → the second three-way 10 → the evaporator 11 → the compressor 4 continues to complete the refrigeration cycle.
The temperature data processing controller 3 collects temperature values fed back by the box temperature probe 1 and the evaporation probe 2, when the box temperature probe 1 reaches a product specified shutdown temperature value, the temperature data processing controller 3 controls the compressor 4 to stop working, when the box temperature probe 1 is raised back to the product specified startup temperature value, the temperature data processing controller 3 controls the compressor 4 to start working, and the product enters a normal startup and shutdown running state.
The temperature data processing controller 3 collects and calculates whether the condition that the temperature difference between the box temperature probe 1 and the evaporation probe 2 is greater than the SET value is satisfied or not in real time, wherein the T1-T2 is calculated. When the condition is not satisfied, the frosting amount of the evaporator is small, and the continuous refrigeration state is not influenced; when the conditions are established, the time comparison stage is entered.
When the defrosting condition T1-T2 > SET, the condition must be maintained for a preset time, which proves that the frosting amount of the evaporator is too much, the heat conduction of the refrigerant is affected, and the system must enter a defrosting stage.
The temperature data processing controller 3 controls the components to enter the defrosting state, the normally closed electromagnetic valve 12 is conducted, the electromagnetic valve 8 is closed, and the refrigerant flows to the compressor 4 → the first three-way 5 (three-way 1) → the normally closed electromagnetic valve 12 → the second three-way 10 (three-way 2) → the evaporator 11 → 4 defrosting cycle. Because the electromagnetic valve 8 is closed, the refrigerant can not be cooled by the component condenser 6, and the high-temperature refrigerant directly enters the evaporator 11 through the component normally closed electromagnetic valve 12 and the second tee joint 10, so that the defrosting effect is achieved.
The temperature data processing controller 3 collects and calculates the temperature of the evaporation probe 2 in real time, and closes the defrosting device after reaching a preset defrosting ending temperature value or defrosting time reaches a preset maximum defrosting operation time value, and then enters a water dripping stage. After the dripping time is over, the refrigerating cycle is started again to finish the intelligent defrosting once.
