Problems solved by technology

[0003] Generally, the frost-free air-cooled refrigerator adopts forced cooling, and the cooling speed is fast. At the same time, due to forced air convection, it is easy to cause air-drying of the food stored in the refrigerator room and other rooms above 0°C, resulting in a sharp decline in freshness preservation.

Embodiment 1

[0018] like figure 1 , 2 , the air-cooled refrigerator of the present invention comprises a refrigerating chamber and a freezing chamber, an air duct, a compressor 4, an evaporator 3, and a CPU are arranged in the casing, and the compressor 4 and the evaporator 3 are all connected to the CPU, and the refrigerant in the evaporator 3 is formed by The compressor 4 is used for cooling, the evaporator 3 is arranged in the air duct, and the cold air is blown by the cooling fan 2 to circulate in the air duct. The air duct is equipped with a cold air outlet corresponding to each compartment, and the refrigerating room and the freezing room share an evaporator. Electric dampers are installed on the outlets, and the electric dampers are connected to the CPU, and the CPU performs centralized program control. The evaporator 3 is arranged at the back of the freezer, and each compartment is provided with a temperature sensor, which is connected to the CPU. The cold air blower 2 is arrange...

Embodiment 2

[0021] The difference between this embodiment and Embodiment 1 is that this embodiment is provided with a refrigerator with three compartments.

[0022] Under normal circumstances, the compressor 4 works, the cooling fan 2 works, and the refrigerating room, the variable room and the freezing room control the opening and closing of the dampers of the respective rooms according to the temperature needs of the respective rooms, so that the temperature in the rooms meets the requirements. When the temperature of each compartment reaches the set requirements, the compressor stops working, at this time the freezer damper 6 is closed, the cooling fan 2 continues to work according to the control requirements, the freezer damper 1 and the variable room (at this time the set temperature is ≥ 0°C) ) The air door 7 is opened, and the cooling fan 2 will bring the water 5 and part of the cooling capacity attached to the evaporator into the refrigerator room and variable temperature room to h...

Embodiment 3

[0025] The difference between the present embodiment and embodiment 1 is that the present embodiment is provided with four compartments, a freezer compartment, a refrigerator compartment, a temperature-changing compartment, and a fruit and vegetable compartment.

[0026] Under normal circumstances, the compressor works, the cooling fan works, and the refrigerating room, variable room and freezing room control the opening and closing of the dampers of each room according to the temperature requirements of their respective rooms, so that the temperature in the rooms meets the requirements. When the temperature of each room reaches the set requirements, the compressor stops working. At this time, the damper of the freezing room is closed, and the cooling fan continues to work according to the control requirements. ℃) The damper is opened, and the cooling fan will bring the moisture attached to the evaporator and part of the cold energy into the refrigerator room and the temp...

Abstract

The invention relates to an air-cooling refrigerator and a control method thereof. The invention provides a refrigerator, which is characterized in that a cooling fan is arranged on the periphery of an evaporator, and condensate water of the evaporator is fully utilized to humidify a compartment of the refrigerator. The refrigerator comprises a refrigerating chamber and a freezing chamber, wherein an air channel, a compressor, the evaporator and a CPU (Central Processing Unit) are arranged in a refrigerator body; the compressor and the evaporator are connected with the CPU; refrigerants in the evaporator is cooled by the compressor; the evaporator is arranged in the air channel; cool air is blown to be cycled in the air channel through the cooling fan; the air channel is provided with a cool air outlet corresponding to each compartment; one evaporator or more than one evaporator is shared by the refrigerating chamber and the freezing chamber; each cool air outlet is provided with a motorized operated damper; and the motorized operated dampers are connected with the CPU and are subjected to concentrate process control by the CPU. The refrigerator has a better moisture effect and a better energy-saving effect, and can be widely applied in the field of refrigerators.

Description

[0001] technical field [0002] The invention relates to an air-cooled refrigerator and a control method thereof. Background technique [0003] Generally, frost-free air-cooled refrigerators use forced cooling, and the cooling speed is fast. At the same time, due to forced air convection, it is easy to cause air-drying of food stored in rooms above 0°C such as refrigerators, resulting in a rapid decline in fresh-keeping function. Contents of the invention [0004] The object of the present invention is to overcome the above defects, and provide a refrigerator in which a cooling fan is arranged around the evaporator and the condensed water of the evaporator is fully used to humidify the refrigerator compartment. [0005] The technical scheme of the air-cooled refrigerator of the present invention is as follows: it includes a refrigerating room and a freezing room, and an air duct, a compressor, an evaporator, and a CPU are arranged in the box, and the compressor and the ev...
