The frozen food in the refrigerator is generally subjected to thawing treatment before being prepared. The current thawing method is to soak the food to be thawed in cold water or warm water which is temporarily prepared, and exchange heat through the cold water or warm water, thereby accelerating thawing. And after thawing is completed, the water used for soaking is usually directly poured out. Thus, after each thawing of the food to be thawed, some water is wasted. When the refrigerator is operated, the temperature of the evaporator is low, so that water vapor in the refrigerator is condensed at the evaporator, typically as frost. In addition, every time the refrigerator door is opened, water vapor outside the refrigerator can enter the refrigerator. Because the temperature in the refrigerator is very low, the water vapor entering the refrigerator is condensed, so that the frost layer attached on the evaporator of the refrigerator is continuously thickened. And when the frost layer attached on the evaporator is too much, the refrigerating effect of the refrigerator is affected. Therefore, when the refrigerator is used normally, the evaporator needs to be defrosted regularly, so that the refrigerating effect of the refrigerator is ensured. The defrosting water generated after defrosting by the evaporator of the refrigerator is difficult to reuse, and the waste of water resources is also caused. Therefore, the food to be defrosted is defrosted by using the defrosting water generated by the refrigerator evaporator, the food to be defrosted does not need to be soaked by tap water, and the recycling rate of the defrosting water is improved. Therefore, when the food to be defrosted is defrosted, the waste of water resources is reduced.

So that the defrost water reaching the first preset temperature flows through the coil assembly. In this way, the defrosting water reaching a specific temperature flows through the coil assembly, so that the coil assembly transfers heat to the food to be defrosted, thereby accelerating the defrosting speed of the food to be defrosted.

Further, the coil assembly 5 includes a carrier tray 6 and a heat transfer tube 7. The object carrying disc 6 is arranged above the heat conducting pipe 7, and the object carrying disc 6 is connected with the outer wall of the heat conducting pipe 7. The tray 6 is used for placing food to be thawed. The water inlet end of the heat conduction pipe 7 is connected with a second water pump 10, and the second water pump 10 conveys defrosting water in the water storage kettle 4 to the heat conduction pipe 7. The defrosting water is controlled to flow through the heat conducting pipe, so that the heat conducting pipe transmits heat to food to be defrosted on the carrying tray, and the food to be defrosted is defrosted. Therefore, the food to be thawed is thawed by utilizing the defrosting water generated by the evaporator of the refrigerator, and the waste of water resources can be reduced in the process of thawing the food to be thawed. In some embodiments, the tray is an aluminum tray and the heat pipe is an aluminum pipe.

Therefore, the flow rate of the defrosting water conveyed by the water storage kettle is regulated by the water valve, and the flow rate of the defrosting water in the coil pipe assembly can be controlled, so that the defrosting speed is controlled.

Further, the thawing apparatus further comprises a thawing chamber 12. The coil pipe assembly 5 is installed in the thawing chamber 12, and a fan 13 is arranged in the thawing chamber 12. The air outlet of the fan 13 faces to the area outside the carrying disc 6. Thus, the food to be thawed can be prevented from being directly blown by the wind blown by the fan. Because of the high heat content of the defrost chamber near the coil assembly. Therefore, the air flow speed in the defrosting room is increased by the fan, so that the heat emitted by the coil assembly is distributed more uniformly in the defrosting room. Therefore, the heat distribution in the defrosting chamber is more uniform through the fan, the contact area between the food to be defrosted and the heat can be increased, the defrosting speed of the food to be defrosted can be increased, and the food to be defrosted can be uniformly defrosted. In addition, the fan does not directly blow the food to be defrosted, so that the rate of water vapor evaporation on the outer surface of the food to be defrosted can be reduced, and the humidity of the food to be defrosted is ensured. Scorching of the outer surface of the food to be thawed can be avoided.

Further, the thawing apparatus further comprises an atomizer, and the atomizer is installed in the thawing chamber. The atomizing nozzle is connected with the evaporating dish through the water storage kettle and is used for spraying water mist to food to be thawed. Specifically, as shown in fig. 1, the atomizing nozzle 14 is connected to the water storage kettle 4 through the water valve 11 and the second water pump 10. The atomizing nozzle 14 is connected with the second water outlet end of the water valve 11. Because the water valve is provided with a water inlet end and two water outlet ends, the speed of the water storage kettle for respectively conveying defrosting water to the coil pipe component and the atomizing nozzle can be controlled. Therefore, the atomizing nozzle atomizes and sprays the defrosting water to the food to be defrosted, so that the humidity of the food to be defrosted can be increased, and the phenomenon that the outer surface of the food to be defrosted is coked due to water shortage is avoided. In addition, the atomizing nozzle can also adjust the speed of spraying water mist through a water valve, so that the humidity of food to be thawed is controlled.

Therefore, impurities of the defrosting water conveyed into the atomizing nozzle can be removed through the water electrolysis mechanism, and the defrosting water sprayed by the atomizing nozzle is prevented from polluting food to be defrosted. And the atomization nozzle can be prevented from being blocked due to impurities in the defrosting water.

Further, the defrosting device further comprises a return pipe 16. One end of the return pipe 16 is connected with the water outlet end of the heat conducting pipe 7 of the coil pipe assembly 5, and the other end is connected with the water storage kettle 4. The return pipe 16 is used to convey the defrost water within the coil assembly 5 back to the kettle 4. Therefore, the defrosting water in the heat conducting pipe is conveyed back to the water storage kettle through the water return pipe, and the defrosting water conveyed back to the water storage kettle can be enabled to participate in defrosting of food to be defrosted again. Therefore, part of defrosting water can be recycled, and water resources are further saved. Optionally, a fourth water pump is provided on the line of the return pipe 16.

Optionally, the thawing device further comprises a second temperature sensor and a humidity sensor, both of which are installed in the thawing chamber. The second temperature sensor is used for detecting the indoor temperature of the thawing chamber, and the humidity sensor is used for detecting the indoor humidity of the thawing chamber. The food to be thawed is thawed by absorbing the heat emitted by the defrosting water. Thus, when the food to be thawed is gradually thawed, the amount of heat absorbed by the food is gradually reduced, resulting in an increase in the temperature in the thawing chamber. As the food to be thawed is gradually thawed, the water to be thawed is gradually precipitated, and the water to be thawed evaporates after absorbing the heat emitted from the defrosting water, thereby increasing the humidity in the thawing chamber. Therefore, by detecting the indoor humidity and the indoor temperature in the defrosting chamber, the defrosting condition of the food to be defrosted can be determined.

Triggering the water electrolysis mechanism to remove impurities from the defrosting water output by the second water outlet end of the water valve, and conveying the defrosting water after removing impurities to the atomizing nozzle. Therefore, the impurities in the defrosting water conveyed to the atomizing nozzle are removed, so that the defrosting water sprayed by the atomizing nozzle is more sanitary, and the defrosting water is prevented from polluting food to be defrosted. And the atomization nozzle can be prevented from being blocked by impurities in the defrosting water.

Further, the refrigerator further comprises a water return pipe, and the water return pipe is arranged in the thawing device. One end of the return pipe is connected with the water outlet end of the coil pipe assembly, and the other end is connected with the water storage kettle. The return pipe is used for conveying the defrosting water in the coil pipe assembly back to the water storage kettle. After the electronic device conveys the defrosting water in the water storage kettle to the coil pipe assembly, the electronic device further comprises: the electronic equipment utilizes the return pipe to convey the defrosting water in the coil pipe assembly back to the water storage kettle. Therefore, the circulating utilization of the defrosting water can be realized by conveying the defrosting water in the water storage kettle to the coil pipe assembly and conveying the defrosting water in the coil pipe assembly back to the water storage kettle. Thereby further saving water resources. Optionally, a fourth water pump is arranged on the pipeline of the water return pipe. The fourth water pump is used for controlling the speed of the return pipe for conveying the return defrosting water to the water storage kettle.

Further, after the electronic device conveys the defrosting water in the coil pipe assembly back to the water storage kettle by utilizing the water return pipe, the electronic device further comprises: the electronic device obtains a thawing state of food to be thawed.

And the electronic equipment conveys the defrosting water in the water storage kettle to the coil pipe assembly under the condition that the second temperature is greater than or equal to a second preset temperature. Wherein the second preset temperature is less than the first preset temperature. And the electronic equipment conveys the defrosting water in the evaporation pan to the water storage kettle under the condition that the second temperature is smaller than a second preset temperature, and conveys the defrosting water in the water storage kettle to the coil pipe assembly under the condition that the second temperature reaches the second preset temperature. Because the defrosting water in the coil pipe assembly can transfer heat to food to be defrosted, when the defrosting water in the coil pipe assembly is conveyed back to the water storage kettle by the water return pipe, the temperature of the defrosting water in the water storage kettle can be reduced. In addition, since the food to be thawed generally takes some time when thawed. When thawing is started, the defrosting water at the first temperature can enable food to be thawed to obtain more heat, so that the food can be thawed quickly. However, the food to be thawed is always at a higher temperature, which is liable to deteriorate its quality, thereby affecting the taste. Therefore, with the continuous increase of the thawing time, when the thawing state of the food to be thawed reaches the first preset state, the temperature of the defrosting water in the water storage kettle is reduced so as to reduce the heat absorbed by the food to be thawed. In this way, thawing is performed in stages, and the quality of the food to be thawed can be better ensured. In some embodiments, the thawing state characterizes the degree of thawing of the food to be thawed. The first preset state characterizes the thawing state of the food to be thawed as a thawing degree of 50%.

Under the conditions that T is less than or equal to-2 ℃ and less than or equal to 0 ℃, and RH is 20 percent and RH is less than or equal to 30 percent, the thawing state of the food to be thawed is 50 percent of the thawing degree. Under the conditions that T is more than 0 ℃ and less than or equal to 5 ℃ and RH is more than 40% and less than or equal to 60% RH, the thawing state of the food to be thawed is 100%.

		T is more than 4 minutes and less than or equal to 6 minutes	Thawing degree 50%
T is more than 8 minutes and less than or equal to 12 minutes	Thawing degree 100%

Further, under the condition that the defrosting state of the electronic equipment reaches a first preset state, detecting the temperature of defrosting water in the water storage kettle through the first temperature sensor to obtain a second temperature, wherein the method comprises the following steps of: under the condition that the defrosting state of the electronic equipment reaches a first preset state, detecting the temperature of defrosting water in the water storage kettle through a first temperature sensor every preset detection duration to obtain a second temperature. Because, after the defrosting water in the coil pipe assembly is conveyed back to the water storage kettle by the water return pipe, the temperature of the defrosting water in the water storage kettle can be reduced. Therefore, the temperature of the defrosting water in the water storage kettle is detected through the preset detection time, and the current temperature of the defrosting water in the water storage kettle can be timely obtained, so that the temperature of the defrosting water in the water storage kettle is adjusted according to the detected temperature. In addition, the temperature detection is carried out at preset detection time intervals, and the power supply can be saved. For example, the preset detection period is 2 minutes.

Further, the method for controlling a refrigerator further includes: the electronic device obtains a thawing state of food to be thawed. And under the condition that the defrosting state reaches a second preset state, stopping conveying the defrosting water in the water storage kettle to the coil pipe assembly. The food to be thawed is thawed by absorbing the heat emitted by the defrosting water. Thus, when the food to be thawed is gradually thawed, the amount of heat absorbed by the food is gradually reduced, resulting in an increase in the temperature in the thawing chamber. As the food to be thawed is gradually thawed, the water to be thawed is gradually precipitated, and the water to be thawed evaporates after absorbing the heat emitted from the defrosting water, thereby increasing the humidity in the thawing chamber. Wherein the second preset state characterizes the thawing state of the food to be thawed as 100% of the thawing degree. Thus, by detecting the indoor humidity and the indoor temperature of the thawing chamber, it is possible to determine whether or not the food to be thawed is completely thawed. So that after the food to be thawed is thawed, the delivery of defrost water in the kettle to the coil assembly is stopped. In this way, after the food to be defrosted is defrosted, defrosting with defrosting water can be stopped in time. Thereby avoiding damaging the quality of the food.

As shown in connection with fig. 4, an embodiment of the present disclosure provides a method for controlling a refrigerator, including:

in step S301, the electronic device detects a temperature of the defrosting water in the water storage kettle in response to a defrosting instruction of a user, and obtains a first temperature.

Step S303, the electronic equipment conveys the defrosting water in the evaporation pan to the water storage kettle, conveys the defrosting water in the water storage kettle to the coil pipe assembly under the condition that the first temperature reaches the first preset temperature, and controls the fan to operate according to the preset rotating speed.

Step S304, the electronic equipment conveys defrosting water in the water storage kettle to the coil pipe assembly, and controls the fan to operate according to a preset rotating speed.

In step S305, the electronic device acquires a thawing state of the food to be thawed.

Step S306, the electronic equipment stops conveying the defrosting water in the water storage kettle to the coil pipe assembly under the condition that the defrosting state reaches a second preset state.

Further, under the condition that the defrosting state of the electronic equipment reaches a second preset state, the fan is controlled to stop running. Thus, after the food to be thawed is thawed, the air flow speed in the thawing chamber is reduced by controlling the fan to stop running, so that the evaporation speed of water on the surface of the food to be thawed is reduced. Thereby ensuring the humidity of the food so that the quality of the food is not damaged. But also can save power.

Further, under the condition that the defrosting state of the electronic equipment reaches a second preset state, triggering the atomizing nozzle to stop running. Therefore, after the food to be thawed is thawed, the atomizing nozzle can be timely controlled to stop spraying water mist. Thereby saving the defrosting water and saving the power supply.

Further, under the condition that the unfreezing state reaches a second preset state, the electronic equipment triggers the water electrolysis mechanism to stop running. Therefore, after the food to be thawed is thawed, the water electrolysis mechanism can be controlled to stop removing impurities from the defrosting water in time, so that a power supply is saved.

Further, the electronic device establishes communication connection with a preset user terminal.
