Embodiment Construction
[0024] This embodiment first provides a refrigerator, which can prevent the heat during the defrosting process from entering the freezing space and affect its internal temperature, and effectively prevent condensation or even freezing into ice on the shunt air supply device, thereby improving the shunt air supply. The working reliability of the wind device. figure 1 It is a schematic structural diagram of a refrigerator 100 according to an embodiment of the present invention. The refrigerator 100 may generally include: a box body 10, a door body, a refrigeration system, a shunt air supply device 20, a heating device, a temperature sensor and a defrost control device.
[0025] Wherein, a plurality of storage spaces may be defined inside the box body 10 . The number and structure of storage spaces can be configured according to needs, figure 1 The first space, the second space and the third space are shown in order up and down; the above storage spaces can be respectively conf...

Disclosed are a defrosting control method for a refrigerator (100) and the refrigerator (100). The defrosting control method for a refrigerator (100) comprises: acquiring a defrosting start signal from the refrigerator (100) (S302); according to the defrosting start signal, enabling a compressor (30), a fan (23), a heating device (40) and a branching air supply device (20) to operate according to an operating state corresponding to the defrosting start signal (S304); acquiring a defrosting end signal from the refrigerator (100), and a temperature at the branching air supply device (20) (S306); and when the temperature at the branching air supply device (20) is less than a first pre-set temperature, enabling the branching air supply device (20) to continuously operate, and when the temperature at the branching air supply device (20) is less than a second pre-set temperature, enabling the branching air supply device (20) to stop continuously operating (S308). By means of the temperature at the branching air supply device (20), whether there is a requirement for preventing condensation or preventing icing at this place is determined, thereby being capable of effectively preventing the branching air supply device (20) from generating condensate and even preventing the condensate from being frozen into ice and improving the operational reliability of the branching air supply device (20), and thus also improving the overall refrigeration effect of the refrigerator (100).
Description
technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a defrosting control method for a refrigerator and the refrigerator. Background technique [0002] With the increasing development of society and the continuous improvement of people's living standards, people's life rhythm is getting faster and faster, so they are more and more willing to buy a lot of food and put them in the refrigerator. The refrigerator has become one of the indispensable household appliances in people's daily life. . [0003] However, the current air-cooled refrigerators have the following disadvantages: during the defrosting process, the heat generated by the heating device often enters the freezing space, causing the temperature of the freezing space to rise, which is not conducive to the storage of food; in addition, after defrosting the evaporator, it may It will cause condensation on the components around the evaporator. More seriously, it may fr...
