Embodiment approach 1

[0026] Embodiment 1 : Below in conjunction with accompanying drawing, specific embodiment of the present invention is described in further detail. Such as figure 1 As shown in the structural diagram of the heat pipe intelligent thawing refrigerator, it is divided into six freezing chambers 101-106 and one cold room 107. There is an insulation layer between the freezing room and the cold room. Each freezing room has a private airtight door 111- 116, all freezers have a common hermetic door 117. Deposit frozen food to freezer 101, open common airtight door 117 earlier, open private airtight door 111 again, the private airtight door 112-116 of other freezers is not opened, reduces cold leakage. The freezing chamber, the refrigerating chamber and the outer shell of the refrigerator are respectively provided with temperature sensors connected with the single chip microcomputer to measure the temperature of the freezing chamber, the refrigerating chamber and the outer shell of t...

Embodiment approach 2

[0034] Embodiment 2 : Heat pipe intelligent thawing refrigerator experimental system and its experimental results.

[0035] Refrigerator controller hardware includes thermistor sensor, amplifying circuit, multiplexer, single-chip microcomputer, multiplexer, solenoid valve, keys, LCD screen, voice module, light-emitting diode and buzzer. The schematic diagram of the heat pipe intelligent defrosting refrigerator controller is as follows: Figure 5 As shown, the temperature sensors 1-6 measure the temperature of the freezer compartments 101-106, the temperature sensor 7 measures the temperature of the refrigerator compartment 107, and the temperature sensor 8 measures the temperature of the outer shell of the refrigerator. Solenoid valves A1-A6 control the flow of refrigerant in the freezing chamber 101-106, solenoid valve A7 controls the flow of refrigerant in the refrigerating chamber 107, and solenoid valves B1-B6 control the solenoid valves of the controlled heat pipe to co...

Abstract

The invention discloses a refrigerator achieving intelligent heat pipe unfreezing and relates to the field of household appliances. According to an existing household refrigerator, the taste is affected and nutrition is lost due to rapid unfreezing of food, and manual operation is needed when food is unfrozen in refrigerating chambers. The refrigerator achieving intelligent heat pipe unfreezing achieves unfreezing in a preset mode by the utilization of a single-chip microcomputer control technology and a controlled heat pipe technology. The refrigerator achieving intelligent heat pipe unfreezing comprises a plurality of heat insulating freezing chambers the refrigerating chambers, the temperature of the freezing chambers and the temperature of the refrigerating chambers are controlled independently, the refrigerating chambers and the freezing chambers are connected through heat pipes, the heat pipes are provided with solenoid valves, and a single-chip microcomputer system controls the solenoid valves to operate or stop. When the heat pipes operate, heat transfer media in the heat pipes flow to the freezing chambers slowly by carrying heat of the refrigerating chambers, frozen food is unfrozen slowly within the time preset by a user, the amount of lost juice is reduced when the frozen food is unfrozen, and the nutrition and taste of food are reserved. Meanwhile, as the multiple independent heat insulating freezing chambers are provided and cold of the freezing chambers flows to the refrigerating chambers slowly, compared with the existing refrigerator, the refrigerator achieving intelligent heat pipe unfreezing can save more electric energy.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a household refrigerator. Background technique [0002] The temperature change curve of frozen food in existing mainstream refrigerators is as follows: figure 2 As shown, stage 1, the food is cooled and frozen; stage 2, the food is in frozen storage; stage 3, the food is taken out of the refrigerator and placed on the thawing plate to thaw naturally; Thaw in warm water or in the microwave. At the dinner table, quickly thawed meat products taste like wood, and some are left on the table and finally discarded. [0003] For experienced users, if the frozen food is transferred from the freezer to the refrigerator in advance, its temperature changes as follows: image 3 As shown, in stage 1, the food is cooled and frozen; in stage 2, the food is in frozen storage; in stage 3, the food is slowly thawed in the refrigerator; in stage 4, the food is taken out of the refrigerator,...
