Problems solved by technology

In the end, there was only quick thawing, because the taste was too bad, some of the food was still thrown away
Thawing is inconvenient, users are either unwilling to use the freezer, or the freezer is full and there is no time to defrost and cook

Embodiment approach 1

[0022] Implementation Mode 1: The structure of the air circulation intelligent thawing refrigerator is as follows figure 1 As shown, it is divided into a plurality of freezing chambers 101-106 and refrigerating chambers 107, and the single-chip microcomputer system independently controls the temperature of each freezing chamber 101-106 and refrigerating chamber 107. In the hot layer, each freezer has a private airtight door 111-116, and all freezers have a common airtight door 117. When storing frozen food in the freezer 101, the common airtight door 117 is opened first, and then the freezer 101 is opened. Private airtight door 111, the airtight door 112-116 privately owned by other freezing chambers 102-106 is not opened, reducing cold leakage. Freezing chamber 101-106 and refrigerating chamber 107 and refrigerator housing are respectively provided with temperature sensors, and they are connected with single-chip microcomputer to measure the temperature of freezing chamber 1...

Embodiment approach 2

[0030] Embodiment 2: Air circulation intelligent thawing refrigerator experimental system and its experimental results.

[0031] Refrigerator controllers are designed such as Figure 5 The structure diagram of the temperature control system of the refrigerator is shown in the figure. The hardware of the controller system includes a thermistor sensor, an amplifier circuit, a multiplexer, a single-chip microcomputer, a multiplexer, a solenoid valve, an air pump, buttons, a liquid crystal screen, a voice module or a light-emitting diode, and a buzzer. 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 C1-C6 (not shown in the figure) control the flow of the refrigerant in the freezing chamber 101-106, and solenoid valve C7 (not shown in the figure) ...

Abstract

The invention discloses an air circulation intelligent thawing refrigerator, which relates to the field of household appliances. In existing household refrigerators, rapid thawing of food affects the taste and causes loss of nutrients, and manual operations are required to thaw food in the refrigerator. The air circulation intelligent thawing refrigerator uses single-chip microcomputer control technology and air circulation technology to realize scheduled thawing. It includes multiple insulated and independently temperature-controlled freezers and refrigerators. The refrigerators and freezers are connected by air inlet pipes and return air pipes. The solenoid valve and air pump are installed on the air inlet pipe and the air return pipe. The single-chip microcomputer system controls the solenoid valve and air pump. The circulating air carries the heat of the refrigerator room and slowly flows into the freezer room. The frozen food is slowly and automatically thawed at the user's appointment time. The nutrition and taste of the food are preserved to the greatest extent. At the same time, due to the design of multiple independently insulated freezer compartments and the slow flow of cold capacity from the freezer compartments into the freezer compartment, it 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 the frozen food in the existing refrigerator is as follows: figure 2 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 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, the fast-thawed meat tastes like wood, and some of the food is left over and thrown away. [0003] For experienced users, when the frozen food is transferred from the freezer to the refrigerator, the temperature of the food changes as follows: image 3 As shown in the temperature change diagram of thawing frozen food in the refrigerator, stage 1, the food is cooled and frozen; stage 2, the food is in the freezer; stage 3, the food is slowly thawed in the refri...
