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

[0023] The structure of air circulation smart 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. The freezing chamber, the refrigerating chamber and the refrigerator shell are provided with temperature sensors respectively, and they are connected with the single-chip microcomputer to measure the temperatures of the freezing chamber, the refrigerating chamber an...

Embodiment approach 2

[0031] Implementation mode 2: Air circulation intelligent thawing refrigerator experimental system and its experimental results.

[0032] 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 t...

Abstract

The invention discloses a wind circulation intelligent thawing-in refrigerator and relates to the field of a household appliance. For a conventional household refrigerator, rapid thawing of foods influences taste and causes nutrition loss and manual operation needs to be carried out to thaw in foods in a refrigerating chamber. The wind circulation intelligent thawing-in refrigerator utilizes a singlechip control technology and a wind circulation technology to implement reservation thawing and comprises a plurality of insulated freezing chambers and refrigerating chambers which are independent in temperature control; the refrigerating chambers and the freezing chambers are connected by air inlet pipelines and air return pipelines; electromagnetic valves and air pumps are mounted on the air inlet pipelines and the air return pipelines; a singlechip system controls the electromagnetic valves and the air pumps; circulating air carries heat of the refrigerating chambers to slowly flow into the freezing chambers; slow and automatic thawing of frozen foods is completed in appointment time set by a user; nutrition and taste of foods are kept to the greatest extent. Meanwhile, the design of a plurality of independent insulated freezing chambers is adopted and cold of the freezing chambers slowly flows into the refrigerating chambers, therefore, compared with the existing refrigerator, the wind circulation intelligent thawing-in refrigerator saves 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 the frozen food in the existing refrigerator is as follows: figure 2 As shown, stage 1, the food is cooled and frozen; stage 2, the food is stored in the freezer; stage 3, the food is taken out of the refrigerator and placed on the thawing plate to thaw naturally; stage 4 is heated and thawed, and the user has no time to wait for the natural thawing. 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; s...
