The surface of the second side wall section 52 facing the hollow structure 53 is provided with a fourth inclined surface 16 adapted to the third inclined surface 15.

In the direction from the hollow structure 53 to the second side wall section 52, the third inclined surface 15 is inclined outwards, and the fourth inclined surface 16 is inclined outwards, on the one hand, when the second door body 8 is opened, sundries falling from the refrigerating space 2 can roll downwards along the fourth inclined surface 16 in time, so that the sundries are prevented from accumulating on the fourth inclined surface 16 to influence the opening and closing of the second door body 8; on the other hand, the contact area of the second side wall section 52 and the hollow structure 53 can be increased, thereby enhancing the sealing effect of the second door 8 against the refrigerating space 2.

Optionally, the hollow structure 53 has a smaller flow area than the first air duct 7 and/or smaller flow area than the second air duct 9.

In this way, the loss of cold energy when passing through the hollow structure 53 can be reduced, and the flow rate of cold air in the hollow structure is greater because the flow area of the hollow structure is smaller. In the case that the cool air enters the second air duct from the first air duct through the hollow structure, the speed of the cool air entering the second air duct from the hollow structure can be increased; in the case where cool air enters the first air duct from the second air duct through the hollow structure, the speed at which cool air enters the first air duct from the hollow structure can be increased.

Alternatively, the first through hole 17 is disposed opposite to the second through hole 18. For example, when the first sidewall section 51 is located above the hollow structure 53, the first through hole 17 is located directly above the second through hole 18; for another example, when the first sidewall section 51 is located to the left of the hollow structure 53, the first through hole 17 is located to the left of the second through hole 18.

Optionally, the refrigerator further includes a first baffle, where the first baffle is openably and closably provided in the second through hole 18 to open or close the second through hole 18.

Thus, when the first door 6 is opened, the first shutter closes the second through hole 18, prevents dirt from entering the hollow structure 53 through the second through hole 18, and prevents cool air in the hollow structure 53 from leaking. When the first door 6 is closed, the first shutter opens the second through hole 18 to communicate the hollow structure 53 with the first air duct 7.

Optionally, the refrigerator further comprises a driving device, wherein the driving device is connected with the main control unit and is in driving connection with the first baffle.

The third through holes 19 are arranged on the surface of the hollow structure 53 facing the second side wall section 52, the fourth through holes 20 are arranged on the surface of the second side wall section 52 facing the hollow structure 53, and the distance between the third through holes 19 and the fourth through holes 20 is reduced, so that the distance between the second air duct 9 and the hollow structure 53 is shortened, the loss of cold energy when air flows between the second air duct 9 and the hollow structure 53 is reduced, and the energy consumption of the refrigerator is reduced.

Optionally, the third through hole 19 is disposed opposite the fourth through hole 20. For example, when the hollow structure 53 is located above the second sidewall section 52, the third through hole 19 is located directly above the fourth through hole 20; for another example, when the hollow structure 53 is located to the left of the first sidewall section 51, the third through hole 19 is located to the left of the fourth through hole 20.

The refrigerator further comprises a second baffle plate, and the second baffle plate is openably and closably arranged at the fourth through hole 20 to open or close the fourth through hole 20.

Thus, when the second door 8 is opened, the second shutter closes the fourth through hole 20, prevents dirt from entering the second air duct 9 through the fourth through hole 20, and prevents cool air in the second air duct 9 from leaking. When the second door 8 is closed, the second shutter opens the fourth through-hole 20 to communicate the second air duct 9 with the hollow structure 53.

Optionally, the refrigerator further comprises a driving device, wherein the driving device is connected with the main control unit and is in driving connection with the second baffle.

When the second door body 8 is opened, the main control unit receives the door opening signal of the second door body 8 to control the driving device to drive the second baffle to close the fourth through hole 20, so that dirt is prevented from entering the second air duct 9 through the fourth through hole 20, and cold air in the second air duct 9 is prevented from leaking. When the second door 8 is closed, the main control unit receives a door closing signal of the second door 8 to control the driving device to drive the second baffle to open the fourth through hole 20, so that the second air duct 9 is communicated with the hollow structure 53.

The second shutter is rotatably or slidably connected to the cabinet 1 such that the second shutter opens or covers the second through hole 18.

The cover shell 21 is covered on the upper surface of the bottom wall 4, the evaporator 22 is positioned in the cover shell 21, so that the distance between the evaporator 22 and the second air duct 9 can be shortened, the transmission efficiency of cold energy between the evaporator 22 and the second air duct 9 is improved, and the loss in the cold energy transmission process is reduced.

Alternatively, the evaporator 22 is a fin evaporator, or, a roll-to-roll evaporator.

Alternatively, the cover 21 is not in contact with the switch door 11, i.e. there is a distance between the cover 21 and the switch door 11. The first tuyere 23 is provided at a surface of the casing 21 facing the opening and closing door 11. It will be appreciated that the first tuyere 23 may also be provided on the surface of the casing 21 facing the top wall 3.

Alternatively, the number of the first tuyeres 23 is one or more, and when a plurality of the first tuyeres 23 are provided, the plurality of the first tuyeres 23 are provided in order in the up-down direction or in order in the left-right direction.

Optionally, the refrigerator further includes a first fan 25, where the first fan 25 is obliquely disposed in the casing 21 and located between the evaporator 22 and the second air duct 9, and the fifth through hole 24 is at least partially higher than the first fan 25, and the first fan 25 is used to drive air in the refrigerating space 2 into the casing 21 from the first air opening 23, or drive air in the casing 21 into the refrigerating space 2 from the first air opening 23.

The first fan 25 is configured to drive air in the refrigeration space 2 to enter the casing 21 from the first air inlet 23, and an air outlet direction of the first fan 25 faces the fifth through hole 24; the first fan 25 is used for driving air in the housing 21 to enter the refrigerating space 2 from the first air port 23, and the air suction direction of the first fan 25 faces the fifth through hole 24.

Optionally, the refrigerator further includes a first fan control system for controlling the air suction and air outlet directions of the first fan 25.

The first fan control system includes a first mode and a second mode, wherein the first mode is to control the first fan 25 to suck air from the first air port 23 and the fifth through hole 24 to discharge air, and the second mode is to control the first fan 25 to suck air from the fifth through hole 24 and the first air port 23 to discharge air.

Alternatively, the first fan 25 is a centrifugal fan, an axial fan, or a rotary fan.

Thus, when the first fan control system is in the mode, in combination with the air flowing direction shown by the arrow in fig. 1, the first fan 25 drives the hot air in the refrigerating space 2 to flow into the housing 21 from the first air inlet 23, the hot air in the housing 21 exchanges heat with the evaporator 22 to form cold air, the cold air flows out of the housing 21 under the driving of the first fan 25 and flows into the second air duct 9 communicated with the housing 21 through the fifth through hole 24, and the cold air in the second air duct 9 can refrigerate the position, corresponding to the second door 8, on the refrigerating space 2, so that the temperature of the refrigerating space 2 is more uniform.

When the first fan control system is in the second mode, the first fan 25 drives hot air in the refrigerating space 2 to flow into the second air duct 9, flows into the housing 21 communicated with the second air duct 9 through the fifth through hole 24, exchanges heat with the evaporator 22 in the housing 21 to form cold air, and the cold air flows out of the housing 21 and enters the refrigerating space 2 under the driving of the first fan 25.

Optionally, the surface of the casing 21 facing the second side wall section 52 and/or the surface of the second side wall section 52 facing the casing 21 is a vertical surface.

By setting the surface of the housing 21 facing the second side wall section 52 and/or the surface of the second side wall section 52 facing the housing 21 as a vertical surface, it is possible to prevent foreign matters falling from the refrigerating space 2 from accumulating on the vertical surface when the door is opened, and to affect the opening and closing of the second door 8.

Optionally, a fifth through hole 24 is provided on a surface of the casing 21 facing the second side wall section 52, and a sixth through hole 26 is provided on a surface of the second side wall section 52 facing the casing 21, and the fifth through hole 24 communicates with the sixth through hole 26 to communicate the casing 21 with the second air duct 9.

Providing the fifth through hole 24 on the surface of the casing 21 facing the second side wall section 52 and providing the sixth through hole 26 on the surface of the second side wall section 52 facing the casing 21 reduces the distance between the fifth through hole 24 and the sixth through hole 26, thereby shortening the distance between the casing 21 and the second air duct 9. This reduces the loss of cold when air flows between the housing 21 and the second duct 9, reduces the energy consumption of the refrigerator, or increases the speed of air flowing between the housing 21 and the second duct 9.

As shown in connection with fig. 1 and 2, the first air duct 7 is optionally provided with a second air opening 27 communicating with the refrigerated space 2, and the second air duct 9 is provided with a third air opening 28 communicating with the refrigerated space 2.

The refrigerator further comprises a second air duct cover plate 30, wherein the second air duct cover plate 30 is used for covering the second air duct 9, and the third air opening 28 is arranged on the second air duct cover plate 30.

In summary, when the first door body 6 and the second door body 8 are closed at the same time, the door body sensor identifies the door closing state of the first door body 6 and the second door body 8, the main control unit receives the door closing signal to cut off the control of the compressor, and the state of the compressor is controlled by the temperature control system.

When the temperature in the refrigerating space 2 collected by the temperature sensor is greater than a set temperature (for example, a starting point), controlling the operation of the compressor to refrigerate in the refrigerating space 2:

when the control system of the first fan 25 is in the mode, the first fan 25 drives hot air in the refrigerating space 2 to flow into the housing 21 from the first air port 23, the hot air in the housing 21 exchanges heat with the evaporator 22 to form cold air, and the cold air flows into the second air duct 9 communicated with the housing 21 under the driving of the first fan 25. Because the first door 6 and the second door 8 are both in the closed state at this time, the door closing signal control driving device of the main control unit connected to the first door 6 and the second door 8 drives the first baffle and the second baffle to open the second through hole 18 and the fourth through hole 20 respectively, so that the cool air can diffuse along the second air duct 9, the hollow structure 53 and the first air duct 7 which are communicated, and flow out to the refrigerating space 2 through the second air port 27 and the third air port 28, so that the temperature of the refrigerating space 2 is more uniform.

When the control system of the first fan 25 is in the second mode, the first fan 25 drives hot air in the refrigerating space 2 to flow into the first air duct 7 and the second air duct 9 from the second air port 27 and the third air port 28 respectively. Because the first door 6 and the second door 8 are in the closed state at this time, the door closing signal control driving device of the main control unit connected to the first door 6 and the second door 8 controls the driving device to drive the first baffle and the second baffle to open the second through hole 18 and the fourth through hole 20 respectively, so that hot air can diffuse along the first air duct 7, the hollow structure 53 and the second air duct 9 which are communicated with each other, then flow into the housing 21 which is communicated with the second air duct 9, cool air is formed after exchanging heat with the evaporator 22 in the housing 21, and flows out from the first air port 23 to the refrigerating space 2 under the driving of the first fan 25, and the cool air can quickly descend to the bottom end of the refrigerating space 2 due to high density of the cool air, so that the refrigerating rate is improved.

When the temperature in the refrigerating space 2 acquired by the temperature sensor is smaller than the set temperature (for example, a shutdown point), the compressor is controlled to stop running, and the energy consumption is reduced.

When the first door body 6 and/or the second door body 8 are/is opened, the door body sensor identifies the door opening state, and the main control unit receives the door opening signal to control the compressor to stop running, so that the energy consumption is reduced, and the leakage of cold energy is avoided.
