Problems solved by technology

[0003] With this control method, since the thermostat in the freezer does not control the start of the compressor, when a large number of warm items are placed in the freezer at one time, the temperature of the freezer rises, while the freezer remains within the specified temperature range. The machine will not start, and the freezer will not cool down, which is not conducive to the freezing of food.
In order to overcome this defect, a manual quick-freezing gear is set on the refrigerator, and its opening and closing are all manually operated by the user. Due to the series relationship between freezing and refrigeration, if the adjustment is improper, frostbite of vegetables and fruits in the refrigerator will inevitably occur.
[0004] This kind of refrigerator also has a weakness: the freezing capacity is low, usually only 3.5Kg of food can be frozen to a temperature below -18 degrees Celsius in 24 hours

Embodiment 1

[0029] The structural technical scheme of the present embodiment is such: it comprises freezing room 5 and cold storage room 2 and its refrigeration system and control circuit, wherein temperature sensor is respectively arranged in freezing room 5 and cold storage room 2, and control circuit comprises main control board, display etc., the temperature sensors in the freezing chamber 5 and the refrigerating chamber 2 are all connected with the main control board in the control circuit; The heating wire is arranged around the evaporator in the refrigerating room. There are two heating wires, one is set on the upper part of the evaporator, and the other is set on the bottom surface of the refrigerating room below the evaporator. The temperature sensor in the refrigerating room includes the evaporator temperature sensor 1, which is set On the evaporator of the refrigerating room, the temperature sensor in the refrigerating room also includes a space temperature sensor 3, which is ar...

Embodiment 2

[0041] The difference between this implementation and Example 1 is that the temperature compensation device is a PTC device, which is located around the evaporator; there is one temperature sensor in the refrigerating room, which is located on the evaporator of the refrigerating room, and the operation of the refrigerator is controlled according to the temperature around the evaporator , its control mode is the same as embodiment 1.

Embodiment 3

[0043] The difference between this embodiment and Embodiment 1 is that the temperature compensation device is set as a combination of lighting lamp, heating wire and PTC device, the heating wire is arranged on the evaporator, and the PTC device is arranged on the bottom surface of the refrigerating room below the evaporator. There are two temperature sensors in the room, that is, the evaporator sensor in the refrigerating room and the space temperature sensor, which work together to control the operation of the refrigerator, and the control method is the same as in Embodiment 1.

Abstract

The invention relates to a refrigerator that the temperatures in the chill chamber and the freezing chamber can maintain within the fixed range and the control method, at the same time, it guarantees the lost cost, simple process, and high efficiency. The refrigerator is made up of freezing chamber and chill chamber, refrigerating system and control circuit, a temperature sensors are arranged in the freezing chamber and the chill chamber, the control circuit includes a primary control board, monitor and so on, the temperature sensors in the two chambers are connected to the primary control board in the control circuit; a temperature compensation device is arranged in the chill chamber, the device is connected to the primary control board, because of the temperature compensation device in the chill chamber, the control method is also changed, thus it realizes the automatic freezing and automatic frost eliminating functions in the two chambers with fixed temperature range, and the freezing speed and the ability are upgraded greatly.

Description

technical field [0001] The present invention relates to a refrigerator and a control method thereof, in particular to a direct cooling refrigerator and a control method thereof. Background technique [0002] Common mechanical temperature control in the prior art, direct-cooling household electric refrigerator generally is made up of two compartments of refrigerating chamber, freezing chamber. Most of the refrigeration circuits adopt single-cycle mode, that is, the two compartments are respectively equipped with evaporators, which are connected in series with compressors, condensers, etc. to form a refrigeration circuit. The start and stop of the compressor is controlled by the temperature sensor placed in the refrigerating evaporator. When the temperature of the refrigerating evaporator is higher than the set start-up temperature, the compressor will run, and the temperature of the two compartments will drop at the same time. When it is lower tha...
