It will be appreciated that the first side wall 41 and the second side wall 42 may also be arranged adjacently, e.g. the first side wall 41 is located at the rear side of the refrigerated space 11 and the second side wall 42 is located at the left or right side of the refrigerated space.

The refrigerator further comprises a shelf 13, wherein the shelf 13 is arranged in the refrigerating space 11 and is used for placing articles needing refrigeration or freezing.

With the refrigerator provided by the embodiment of the present disclosure, there are two opposite doors (a door body 5 and a switch door 12) on the refrigerator, the switch door 12 is regarded as a front door, and the door body 5 is regarded as a rear door. Thus, when the rear door is opened during replenishment, the commodities at the rear side of the shelf 13 are moved forward to the front side of the shelf 13, and then the residual positions at the rear side of the shelf 13 are replenished, so that the problem of long-term backlog of the commodities at the rear side is solved, and the problem of first-in first-out of the commodities during replenishment is solved.

As shown in connection with fig. 1, the refrigerator optionally further comprises a first fan 14, wherein the first fan 14 is arranged in the housing 7 and is used for driving air in the refrigerating space 11 from the first air opening 9 into the housing 7 or driving air in the housing 7 from the first air opening 9 into the refrigerating space 11.

Alternatively, the casing 7 is not in contact with the opening and closing door 12, i.e. there is a distance between the casing 7 and the opening and closing door 12. The first tuyere 9 is provided at a surface of the casing 7 facing the opening and closing door 12. It will be appreciated that the first tuyere 9 may also be provided at the surface of the casing 7 facing the top wall 2.

Optionally, the refrigerator further includes a first fan control system for controlling the direction of air suction and air discharge of the first fan 14.

The first fan control system comprises a first mode and a second mode, wherein the first mode is used for controlling the first fan 14 to suck air from the first air port 9 and the first through hole 10 to discharge air, and the second mode is used for controlling the first fan 14 to suck air from the first through hole 10 and the first air port 9 to discharge air.

Alternatively, the first fan 14 is a centrifugal fan, an axial fan, or a rotary fan.

Alternatively, the evaporator 8 is a fin evaporator, or, a roll-to-roll evaporator.

Optionally, the first fan 14 is obliquely disposed in the housing 7 and located between the evaporator 8 and the air duct 6, and the first through hole 10 is at least partially higher than the first fan 14.

The first fan 14 is used for driving air in the refrigerating space 11 to enter the housing 7 from the first air port 9, and the air outlet direction of the first fan 14 faces the first through hole 10; the first fan 14 is used for driving air in the housing 7 to enter the refrigerating space 11 from the first air port 9, and the air suction direction of the first fan 14 faces the first through hole 10.

Thus, when the first fan control system is in the mode, the first fan 14 drives the hot air in the refrigerating space 11 to flow into the housing 7 from the first air port 9, the hot air in the housing 7 exchanges heat with the evaporator 8 to form cold air, the cold air flows out of the housing 7 under the driving of the first fan 14 and flows into the air duct 6 communicated with the housing 7 through the first through hole 10, and the cold air in the air duct 6 can refrigerate the position, corresponding to the door body 5, on the refrigerating space 11, so that the temperature of the refrigerating space 11 is more uniform.

When the first fan control system is in the second mode, the first fan 14 drives hot air in the refrigerating space 11 to flow into the air duct 6, flows into the housing 7 communicated with the air duct 6 through the first through hole 10, exchanges heat with the evaporator 8 in the housing 7 to form cold air, and the cold air flows out of the housing 7 and enters the refrigerating space 11 under the driving of the first fan 14.

Optionally, a first through hole 10 is provided on a surface of the housing 7 facing the side wall 4, and a second through hole 15 is provided on a surface of the side wall 4 facing the housing 7, and the first through hole 10 communicates with the second through hole 15, so that the housing 7 communicates with the air duct 6.

The first through hole 10 is formed in the surface of the housing 7 facing the side wall 4, and the second through hole 15 is formed in the surface of the side wall 4 facing the housing 7, so that the distance between the first through hole 10 and the second through hole 15 is reduced, and the distance between the housing 7 and the air duct 6 is shortened. This reduces the loss of cooling energy when air flows between the casing 7 and the duct 6, reduces the energy consumption of the refrigerator, or increases the speed of air when air flows between the casing 7 and the duct 6.

Optionally, the surface of the casing 7 facing the side wall 4 and/or the surface of the side wall 4 facing the casing 7 is a vertical face.

By setting the surface of the cover 7 facing the side wall 4 and/or the surface of the side wall 4 facing the cover 7 as a vertical surface, it is possible to prevent foreign matters falling in the refrigerating space 11 from accumulating on the vertical surface during door opening and to affect the opening and closing of the door body 5.

Optionally, the air duct 6 is provided with a second air opening 16 communicating with the refrigerated space 11.

In summary, when the door body 5 is closed, the door body sensor recognizes the door closing state of the door body 5, 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 11 collected by the temperature sensor is greater than a set temperature (for example, a starting point), the compressor is controlled to operate to refrigerate in the refrigerating space 11. When the first fan control system is in a mode, the first fan 14 drives hot air in the refrigerating space 11 to flow into the housing 7 from the first air opening 9, the hot air in the housing 7 exchanges heat with the evaporator 8 to form cold air, the cold air flows into the air duct 6 communicated with the housing 7 under the driving of the first fan 14, and the cold air in the air duct 6 flows into the refrigerating space 11 from the second air opening 16, so that the corresponding part of the refrigerating space 11 and the door body 5 can be refrigerated, and the temperature of the refrigerating space 11 is more uniform. When the first fan control system is in the second mode, the first fan 14 drives hot air in the refrigerating space to flow into the air duct 6 from the second air opening 16, then flows into the housing 7 communicated with the air duct 6, exchanges heat with the evaporator 8 in the housing 7 to form cold air, and the cold air flows into the refrigerating space 11 from the first air opening 9 under the driving of the first fan 14.

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

When the door body 5 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 is avoided.

Embodiment two:

Wherein, the door body 5 is openably and closably arranged on the first side wall section 19, and the installation space 21 is communicated between the air duct 6 and the housing 7.

Optionally, the refrigerator further comprises a second fan 22, wherein the second fan 22 is arranged in the installation space 21 and is used for driving air in the refrigerating space 27 to enter the housing 7 from the first air opening 9 or driving air in the housing 7 to enter the refrigerating space 11 from the first air opening 9.

The second fan 22 is used for driving air in the refrigerating space 11 to enter the housing 7 from the first air port 9, and the air outlet direction of the second fan 22 faces the air duct 6; the second fan 22 is used for driving air in the housing 7 to enter the refrigerating space 11 from the first air port 9, and the air suction direction of the second fan 22 faces the air duct 6.

Optionally, the refrigerator further comprises a second fan control system for controlling the air suction and air outlet directions of the second fan 22.

The second fan control system comprises a third mode and a fourth mode, wherein the third mode is used for controlling the second fan 22 to suck air from the first air port 9 and the air duct 6 to discharge air, and the fourth mode is used for controlling the second fan 22 to suck air from the air duct 6 and the air from the first air port 9.

Thus, when the second fan control system is in the third mode, the second fan 22 drives the hot air in the refrigerating space 11 to flow into the housing 7 from the first air port 9, the hot air in the housing 7 exchanges heat with the evaporator 8 to form cold air, the cold air firstly flows into the installation space 27 and then flows into the air duct 6 under the driving of the second fan 22, and the cold air in the air duct 6 can refrigerate the position, corresponding to the door body 5, on the refrigerating space 11, so that the temperature of the refrigerating space 11 is more uniform.

When the second fan control system is in the fourth mode, the second fan 22 drives hot air in the refrigerating space to flow into the air duct 6 and then into the installation space 21 and finally flow into the housing 7, heat exchange is carried out between the hot air and the evaporator 8 in the housing 7 to form cold air, the cold air flows out of the housing 7 and enters the refrigerating space 11 under the driving of the second fan 22, and the cold air has high density and high descending speed, so that the cold air can quickly descend to the bottom end of the refrigerating space 11, and the refrigerating speed is improved.

Alternatively, the second side wall section 20 is directly connected to the bottom wall 3, and the mounting space 21 is located at the bottom end of the second side wall section 20.

In this way, the installation space 21 is provided at the bottom end of the second side wall section 20 for better stability.

Optionally, a third through hole 23 is provided on the surface of the first side wall section 19 facing the second side wall section 20, a fourth through hole 24 is provided on the surface of the second side wall section 20 facing the first side wall section 19, and the third through hole 23 communicates with the fourth through hole 24, so that the air duct 6 communicates with the installation space 21.

The third through hole 23 is formed in the surface of the first side wall section 19 facing the second side wall section 20, and the fourth through hole 24 is formed in the surface of the second side wall section 20 facing the first side wall section 19, so that the distance between the third through hole 23 and the fourth through hole 24 is reduced, and the distance between the air duct 6 and the installation space 21 is shortened. The loss of cold energy when air flows between the air duct 6 and the installation space 21 is reduced, the energy consumption of the refrigerator is reduced, or the speed of air flowing between the air duct 6 and the installation space 21 is increased.

Optionally, the refrigerator further includes a baffle plate, where the baffle plate is openably and closably provided in the fourth through hole 24 to open or close the fourth through hole 24.

Thus, when the door 5 is opened, the shutter closes the fourth through hole 24, prevents dirt from entering the installation space 21 through the fourth through hole 24, and prevents cool air in the installation space 21 from leaking. When the door 5 is closed, the shutter opens the fourth through hole 24 to communicate the installation space 21 with the duct 6.

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 baffle plate.

When the door body 5 is opened, the main control unit receives the door opening signal of the door body 5 to control the driving device to drive the baffle to close the fourth through hole 24, so that dirt is prevented from entering the installation space 21 through the fourth through hole 24, and cold air in the installation space 21 is prevented from leaking. When the door body 5 is closed, the main control unit receives a door closing signal of the door body 5 to control the driving device to drive the baffle to open the fourth through hole 24, so that the installation space 21 is communicated with the air duct 6.

Optionally, the baffle is rotatably or slidably coupled to the cabinet such that the baffle opens or covers the fourth through-hole 24.

Optionally, the surface of the first side wall section 19 facing the second side wall section 20 is provided with a first inclined surface 25, the first inclined surface 25 being inclined inwardly in the direction from the second side wall section 20 to the first side wall section 19; the surface of the second side wall section 20 facing the first side wall section 19 is provided with a second inclined surface 26 adapted to the first inclined surface 25.

In the direction from the second side wall section 20 to the first side wall section 19, the first inclined surface 25 is inclined inwards, and the second inclined surface 26 is inclined inwards, so that on the one hand, when the door body 5 is opened, sundries falling from the refrigerating space 11 can roll downwards along the second inclined surface 26 in time, and the sundries are prevented from accumulating on the second inclined surface 26 to influence the opening and closing of the door body 5; on the other hand, the contact area of the first side wall section 19 and the second side wall section 20 can be increased, thereby enhancing the sealing effect of the door body 5 to the refrigerating space 11.

In summary, when the door body 5 is closed, the door body sensor recognizes the door closing state of the door body 5, 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. And, the main control unit receives the door closing signal of the door body 5 to control the driving device to drive the baffle plate to open the fourth through hole 24, so that the air duct 6 is communicated with the installation space 21, and air can flow into the installation space 21 from the air duct 6 or flow into the air duct 6 from the installation space 21.

When the temperature in the refrigerating space 11 collected by the temperature sensor is greater than a set temperature (for example, a starting point), the compressor is controlled to operate to refrigerate in the refrigerating space 11. When the second fan control system is in the third mode, the second fan 22 drives hot air in the refrigerating space 11 to flow into the housing 7 from the first air opening 9, the hot air in the housing 7 exchanges heat with the evaporator 8 to form cold air, the cold air firstly flows into the installation space 21 and then flows into the air duct 6 under the driving of the second fan 22, and the cold air in the air duct 6 flows into the refrigerating space 11 from the second air opening 16, so that the corresponding part of the door body 5 on the refrigerating space 11 can be refrigerated, and the temperature of the refrigerating space 11 is more uniform. When the second fan control system is in the fourth mode, the second fan 22 drives hot air in the refrigerating space 11 to flow into the air duct 6 from the second air opening 16, then flow into the installation space 21 and finally flow into the housing 7, heat exchange is carried out between the hot air and the evaporator 8 in the housing 7, so that cold air is formed, the cold air flows into the refrigerating space 11 from the first air opening 9 under the driving of the second fan 22, and the descending speed is high due to the high density of the cold air, so that the cold air can be quickly reduced to the bottom end of the refrigerating space 11, and the refrigerating speed is improved.

When the temperature in the refrigerating space 11 collected 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 door body 5 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 is avoided. Moreover, when the door body 5 is opened, the main control unit receives the door opening signal of the door body 5 to control the driving device to drive the baffle to close the fourth through hole 24, so that dirt is prevented from entering the installation space 21 through the fourth through hole 24, and the installation space 21 is kept clean.
