Problems solved by technology

[0003] The technical problems in the above process are: 1. The temperature detected by the defrosting temperature sensor installed in the refrigerator is the temperature of its location, and the temperature value cannot fully represent the ambient temperature inside the refrigerator, so the defrosting temperature sensor detects the temperature Inaccurate, it will cause the defrosting inside the refrigerator to be unclean, or cause the defrosting heater to still work when the defrosting inside the refrigerator is completed; However, the defrosting heater is generally arranged at the bottom of the refrigerator, and the radiant heat from the defrosting heater alone cannot discharge the residual ice from the air duct and damper in time. There is no cooling

Embodiment 1

[0044] Such as Figure 1-2 As shown, this embodiment provides a refrigerator, which includes: an evaporator 1 , a defrosting heater 2 , a freezing fan 3 , a fan defrosting heating wire 4 , a freezing and refrigerating damper 5 , and a fan defrosting heating wire 6 . Compared with the existing refrigerator, heating wires for the freezing air duct are added, and the heating wires for the freezing air duct include fan defrosting heating wires 4 and damper defrosting heating wires 6 . The fan defrosting heating wire 4 is half surrounded on the outside of the freezing fan 3 , and the heating part of the damper defrosting heating wire 6 is arranged in the freezing and refrigerating damper 5 .

[0045] When the refrigerator is in the cooling mode, the compressor starts, the heating wire of the freezing air duct and the defrosting heater 2 are closed, the freezing and refrigerating damper 5 is opened, and the freezing fan 3 is started; Shut down, the freezing air duct heating wire an...

Embodiment 2

[0047] This embodiment provides a defrosting control method for a refrigerator. The internal volume of the refrigerator described in this embodiment is 500 L. The internal structure of the refrigerator is consistent with that of the refrigerator provided in Example 1. The defrosting control method Process such as figure 2 shown, including:

[0048] S1, set and record the refrigerating compartment gear t of the refrigerator lc , set and record the freezer stall t of the refrigerator ld , the refrigerator is in cooling mode at this time;

[0049] S2, detect and record the ambient temperature t outside the refrigerator hj , set five consecutive temperature zones from high temperature to low temperature, set the temperature zone less than or equal to 10°C as the first temperature zone, set the temperature zone greater than 10°C and less than or equal to 20°C as the second temperature zone, set The temperature range greater than 20°C and less than or equal to 30°C is defined a...

Embodiment 3

[0054] This embodiment provides a defrosting control method for a refrigerator. The internal volume of the refrigerator described in this embodiment is 400 L. The internal structure of the refrigerator is consistent with that of the refrigerator provided in Embodiment 1. The defrosting control method includes :

[0055] S1, set and record the refrigerating compartment gear t of the refrigerator lc , set and record the freezer stall t of the refrigerator ld , the refrigerator is in cooling mode at this time;

[0056] S2, detect and record the ambient temperature t outside the refrigerator hj , set five consecutive temperature zones from high temperature to low temperature, set the temperature zone less than or equal to 10°C as the first temperature zone, set the temperature zone greater than 10°C and less than or equal to 20°C as the second temperature zone, set The temperature range greater than 20°C and less than or equal to 30°C is defined as the third temperature range, ...

Abstract

The invention relates to a refrigerator, which is provided with a heating wire of a freezing air duct inside the refrigerator. The present invention also relates to a defrosting control method for a refrigerator, comprising: setting and recording the refrigerating chamber gear tlc of the refrigerator, setting and recording the freezing chamber gear tld of the refrigerator; detecting and recording the ambient temperature thj outside the refrigerator; recording The compressor of the refrigerator accumulates the start-up time Ti and the number of times Ni of the refrigerator door to be opened and closed, and judges whether to switch from the cooling mode to the defrosting mode according to the temperature zone where the ambient temperature thj is located, the value of Ti and the value of Ni; the refrigerator switches to the defrosting mode Finally, turn on the defrosting heater and the cooling air duct heating wire at the same time, record the working time Ths of the defrosting heater, and record the working time T6 of the freezing air duct heating wire; The heating wire is turned off; judge whether to turn off the defrosting heater according to the value of Ths and Thsi.

Description

technical field [0001] The invention relates to a refrigerator control technology, in particular to a refrigerator and a method for controlling defrosting of the refrigerator. Background technique [0002] At present, the refrigerator usually determines whether to enter the defrost mode according to the running time of the compressor and the power-on time. After the refrigerator enters the defrost mode, the defrost heater will be activated. The refrigerator will exit the defrost mode when it detects that the ambient temperature inside the refrigerator is higher than the preset temperature. [0003] The technical problems in the above process are: 1. The temperature detected by the defrosting temperature sensor installed in the refrigerator is the temperature of its location, and the temperature value cannot fully represent the ambient temperature inside the refrigerator, so the defrosting temperature sensor detects the temperature Inaccurate, it will cause the defrosting in...
