Embodiment 1

[0033] Such as figure 1 , combined with figure 2 Shown is the structure of the freezer evaporator part of the air-cooled refrigerator defrosting system proposed in this embodiment, including the freezer evaporator 1, and the freezer evaporator 1 is provided with a freezer defrosting assembly. The freezer defrosting assembly is used to heat and defrost the evaporator 1 in the freezer of the air-cooled refrigerator when the air-cooled refrigerator is defrosting. As a further embodiment, the defrosting assembly for the freezing chamber includes a first defrosting component 3 arranged below the bottom of the freezing chamber evaporator 1 and a second defrosting component 3 arranged on the side wall of the freezing chamber evaporator 1 . Frost part2. In this embodiment, the freezer defrosting assembly only includes the first defrosting part 3 and the second defrosting part 2, but in the actual implementation process, it is not limited to only including the above two defrosting p...

Embodiment 2

[0043] This embodiment discloses a method for controlling the defrosting system of an air-cooled refrigerator, which is used for controlling the defrosting system of an air-cooled refrigerator as described in Embodiment 1. The specific control method is: when the air-cooled refrigerator enters the defrosting stage, the circuit control board controls the controller to turn on the first defrosting part and the second defrosting part in sequence.

[0044] As a further control scheme, the program is pre-written in the circuit control board, so that the temperature rise rate of the second defrosting part from the start to greater than or equal to the first predetermined temperature is V1, and the first defrosting part is from The speed of temperature rise during the process of turning on to be greater than or equal to the second predetermined temperature is V2, and it is ensured that the speed V1 is less than the speed V2 during the temperature rise process.

[0045] When the tempe...

Embodiment 3

[0051] Such as figure 2 Shown is an air-cooled refrigerator proposed in this embodiment, and the air-cooled refrigerator is provided with the defrosting system of the air-cooled refrigerator as described in Embodiment 1. In addition to being provided with the defrosting system of the air-cooled refrigerator in Embodiment 1, the air-cooled refrigerator is also provided with a freezer fan 6 for delivering cold air from the freezer to the freezer, and a refrigerating room that delivers cold air from the refrigerator to the refrigerating room. Fan 8, condenser 7, solenoid valve 10 and compressor 11.

[0052] When the temperatures in both the refrigerator compartment and the freezer compartment are greater than the set temperature value, the compressor 11 starts, and the freezer compartment evaporator 1 and the refrigerator compartment evaporator 9 start to refrigerate. After the refrigeration started, the freezer fan 6 and the refrigerating room fan 8 started to run, and at this...

Abstract

The invention relates to the field of refrigerators and discloses a defrosting system of an air-cooled refrigerator, a control method for the defrosting system and the air-cooled refrigerator. The defrosting system of the air-cooled refrigerator comprises a freezing chamber evaporator; the freezing chamber evaporator is provided with a freezing chamber defrosting assembly; the freezing chamber defrosting assembly comprises a first defrosting component and a second defrosting component which are respectively arranged below the bottom part of the freezing chamber evaporator and on the side wall of the freezing chamber evaporator; the first defrosting component and the second defrosting component are connected with a circuit control board through a controller. According to the defrosting system of the air-cooled refrigerator, disclosed by the invention, the freezing chamber defrosting assembly comprises the first defrosting component and the second defrosting component which are respectively arranged below the bottom part of the freezing chamber evaporator and on the side wall of the freezing chamber evaporator, and the freezing chamber defrosting assembly is capable of respectively heating the bottom part and the side wall of the freezing chamber evaporator, so that the whole freezing chamber evaporator is heated more evenly, and the phenomenon that local frost cannot be melted during the defrosting process is avoided.

Description

technical field [0001] The invention relates to the field of air-cooled refrigerators, and more particularly to an air-cooled refrigerator defrosting system and a control method thereof, and an air-cooled refrigerator. Background technique [0002] In the refrigerator industry, air-cooled refrigerators are the mainstream products that major refrigerator manufacturers are vigorously researching and developing. The research and development of air-cooled refrigerators mainly focuses on the research on air duct systems and defrosting systems. [0003] Air-cooled refrigerators are also called frost-free refrigerators. They are named because there will be no frost inside the refrigerator during use. At the same time, it is also because of the above reasons that air-cooled refrigerators are loved by consumers. The working principle of the air-cooled refrigerator is to use air for cooling. When the high-temperature air from the outside flows through the evaporator installed inside t...
