Embodiment approach 1

[0026] Embodiment 1: The specific embodiment of the present invention will be further described in detail below in conjunction with the accompanying drawings. 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 ...

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 contr...

Abstract

The invention discloses a heat pipe intelligent thawing refrigerator, which relates to the field of household appliances. In existing household refrigerators, rapid thawing of food affects taste and causes nutrient loss, and manual operations are required to thaw food in the refrigerator. The heat pipe intelligent thawing refrigerator utilizes single-chip microcomputer control technology and controlled heat pipe technology to realize scheduled thawing. It includes a plurality of heat-insulated independent temperature-controlled freezers and refrigerators. The refrigerators and freezers are connected by heat pipes. The heat pipes are equipped with solenoid valves. The single-chip microcomputer system controls the operation and stop of the solenoid valves. The heat medium carries the heat from the refrigerator and slowly flows into the freezer, and the frozen food is slowly thawed at the user's appointment time, reducing the loss of juice when the frozen food is thawed, and retaining the nutrition and taste of the food. At the same time, due to the design of multiple independently insulated freezers and the slow flow of cold from the freezer into the freezer, the heat pipe smart defrosting refrigerator saves electricity compared to existing refrigerators.

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,...
