Embodiment 1

[0058] The refrigerator provided in this embodiment is a single-system air-cooled frost-free refrigerator that includes a compartment with an independent wide temperature range. The orientation is -23°C~-15°C, and the setting range of the variable room 4 is -23°C~8°C. The temperature of the evaporator 2 is 8°C at the end of the defrosting of this air-cooled refrigerator, that is, the second preset temperature is 8°C, and the longest running time of the electric heater 3 during the defrosting process is 80 minutes, that is, the setting of the electric heater 3 The heating time is set to 80min.

[0059] In this embodiment, the specific instant temperature setting of the refrigerating chamber 6 is 6°C, the specific instant setting temperature of the freezing chamber 5 is -15°C, and the initial setting temperature of the variable room 4, that is, the temperature before the temperature rise, is -12°C, namely The first preset temperature is -12°C, and the temperature of the variabl...

Abstract

The invention relates to a method for raising the temperature of the temperature-changing room of an air-cooled refrigerator, which comprises the following steps: setting the temperature-raising setting temperature of the variable room; normal cooling, making the temperature of the freezing room and the refrigerating room reach the instant setting temperature, and the temperature of the evaporator is lower than The first preset temperature; turn off the compressor, turn on the electric heater and the variable temperature door; when the temperature of the evaporator rises to the first preset temperature, turn on the fan; judge whether the temperature reaches the set temperature for heating; judge the temperature of the evaporator Whether the temperature rises to the second preset temperature and / or the heating time of the electric heater reaches the set heating time; turn off the electric heater, the fan and the air door of the variable room to realize the temperature rise of the variable room. The invention uses the heater connected to the evaporator to heat, and the heat is sent to the variable room through the air path, and the forced convection heat exchange is realized in the variable room, which improves the heating efficiency, ensures the uniformity of temperature rise in the variable room, and reduces the temperature of the refrigerator. production cost.

Description

technical field [0001] The invention belongs to the technical field of temperature regulation of a variable temperature chamber of an air-cooled refrigerator, and in particular relates to a method for raising the temperature of a variable temperature chamber of an air-cooled refrigerator. Background technique [0002] With the development of the social economy and the improvement of people's living standards, refrigerators have become an indispensable household appliance in people's daily life. In the cooling method of the variable room, it is only necessary to add an evaporator in the variable room or send cold air from other rooms to the variable room to meet the cooling effect of the variable room. However, in the current method of heating the variable greenhouse, most manufacturers use the method of pasting aluminum foil heating wires on the inner tank to heat the variable greenhouse, which not only increases the complexity of the internal structure of the refrigerator, ...
