The synchronous opposite adjustment of the opening degrees of the two air supply outlets is realized.

The user can adaptively switch the opening degrees of the two air supply openings of the air supply assembly according to the change of the storage demand, make full use of the space of the two storage compartments, and meet the storage demand.

[0055] See Figure 6 , as an embodiment, the upper air duct assembly of the present invention includes an upper cover plate 3 and an upper air duct plate 4; combined with Figure 7 , an upper ventilation duct 42 is arranged in the upper air duct plate 4, and an upper air inlet 41 for communicating with the air supply opening of the air supply assembly is arranged at one end of the upper ventilation duct 42; cold air flow is introduced into the upper ventilation duct 42 from the upper air inlet 41.

[0056] Furthermore, a damper for adjusting the air inflow is arranged at the upper air inlet 41.

[0057] An installation cavity 31 is formed on one side of the upper air duct plate 4, and a feedback temperature sensor 35 fixedly arranged on the upper cover plate 3 is arranged in the installation cavity 31;

[0058] The refrigerator of the present invention further has a control unit, and the control unit has a comparison module;

[0059] A direct display temperature sensor is arranged in the upper storage compartment 11 for detecting the actual temperature in the upper storage compartment 11.

[0060] The feedback temperature sensor 35 is used to detect the temperature and send a corresponding feedback signal to the control unit;

[0061] The comparison module is configured to: receive the preset temperature value T input by the control unit 设 and the temperature feedback value T input by the feedback temperature sensor 35 反 ; compare the magnitude relationship between T 设 and T 反 and send a corresponding control signal to the refrigeration system of the refrigerator according to the comparison result; specifically:

[0062] T 设 ≥T 反 , send a shutdown signal to the refrigeration system; no longer send cold air flow to the upper ventilation duct 42.

[0063] T 设 <T 反 , the refrigeration system keeps running or sends a start signal to the refrigeration system; make the upper ventilation duct 42 admit cold air flow to maintain or restore the refrigeration function.

[0064] Optionally, the control unit of the present invention can send control signals to the compressor, the centrifugal fan 2 or the air damper. Regulate the on / off of the cold air flow in the upper ventilation duct 42.

[0065] As an embodiment, refer to Figure 7 and Figure 8 , a wind dam 43 is convexly provided in the upper ventilation duct 42, an air guiding cavity is opened in the wind dam 43, and a wind regulating seat 6 is rotatably arranged in the air guiding cavity; an air guiding duct 44 communicating the upper ventilation duct 42 and the air guiding cavity is also opened on the wind dam 43; part of the cold air flow in the upper ventilation duct 42 can be introduced into the air guiding cavity through the air guiding duct 44.

[0066] Combined with Figure 9 , a side ring plate 62 is fixedly provided around the wind regulating seat 6, and the area surrounded by the side ring plate 62 forms a wind storage cavity 63; a plurality of ventilation holes 61 communicating the wind storage cavity 63 are opened on the end face of the wind regulating seat 6; a ventilation notch 64 is opened on the side ring plate 62;

[0067] A bypass air duct 32 capable of communicating the wind storage cavity 63 and the installation cavity 31 is clamped between the upper cover plate 3 and the upper air duct plate 4;

[0068] The wind regulating seat 6 is configured to: rotate in the air guiding cavity to adjust the opening degree of the ventilation notch 64 relative to the bypass air duct 32, and further adjust the flow rate of the cold air flow in the bypass air duct 32;

[0069] The present invention adjusts the running time of the refrigeration system by adjusting the opening degree of the ventilation notch 64 relative to the bypass air duct 32; specifically:

[0070] If the opening degree of the ventilation gap 64 relative to the bypass air duct 32 is large, the flow rate of the cold air flow in the bypass air duct 32 is large, and the temperature value T detected by the feedback temperature sensor 35 反 , can quickly reach or be lower than the preset value T 设 ; thereby shortening the operating time of the refrigeration system;

[0071] If the opening degree of the ventilation gap 64 relative to the bypass air duct 32 is small, the flow rate of the cold air flow in the bypass air duct 32 is small, and the temperature value T detected by the feedback temperature sensor 35 反 , can reach or be lower than the preset value T 设 for a longer time, thereby increasing the operating time of the refrigeration system.

[0072] As an implementation manner, the present invention can set a target refrigeration temperature, that is, the temperature preset value T 设 ; for example, T 设 =-20°C;

[0073] When the bypass air duct 32 of the upper air duct assembly is closed and no cold air flow is blown to the feedback temperature sensor 35, when the actual temperature in the storage room reaches or is lower than -20°C, the refrigeration system stops.

[0074] The present invention sets a bypass air duct 32 in the upper air duct assembly to blow cold air flow to the feedback temperature sensor 35, so that the temperature feedback value T 反 quickly reaches T 设 ≥T 反 state, so that the refrigeration system stops; at this time, the actual temperature in the upper storage room 11 can be measured by the direct display temperature sensor.

[0075] After the refrigeration system stops, after a period of time, the temperature feedback value T detected by the feedback temperature sensor 35 反 >T 设 ; at this time, the refrigeration system starts, and the upper air duct assembly blows cold air flow to the feedback temperature sensor 35 again until the refrigeration system stops, completing a refrigeration cycle.

[0076] By adjusting the flow rate of the cold air flow through the upper air duct assembly, the actual temperature in the upper storage room 11 can be adjusted. For example, the actual temperature in the upper storage room 11 can be controlled to be between -5°C and -10°C; or between 0°C and 10°C; without changing the structure of the refrigeration system, the temperature control range of the upper storage room 11 is greatly increased, realizing the cross-temperature zone temperature adjustment of the storage room, improving the storage function, and meeting diverse storage requirements.

[0077] As an embodiment, an installation seat 33 for fixing the feedback temperature sensor 35 is provided in the installation cavity 31;

[0078] Furthermore, a plurality of air guiding holes 34 are formed in the mounting base 33, so that the cold air flow blows uniformly towards the feedback temperature sensor 35, improving the control accuracy.

[0079] As an embodiment, a knob 5 for connecting the air regulating base 6 is provided on the upper cover plate 3; by rotating the knob 5, the opening degree of the ventilation notch 64 relative to the bypass air duct 32 can be conveniently adjusted;
