Referring to fig. 1 to 5, a preferred embodiment of the present invention provides a refrigerator, which may also be other refrigeration equipment adopting an air cooling method.

Specifically, as shown in fig. 1, the refrigerator includes a refrigerator body 10 and a door 20 pivotally connected to the refrigerator body 10. In this embodiment, the refrigerator further includes a refrigeration air duct disposed in the refrigerator body 10, and a compressor, a condenser, and an evaporator connected by a pipeline to cool the refrigerator body 10 and the storage compartments in the door body. The cold energy generated by the evaporator in the evaporation chamber can be continuously transmitted to each storage chamber from the refrigeration air channel through the evaporation fan. The door body 20 is a refrigerating chamber door body positioned at the upper side of the refrigerator, so that a user can conveniently take and use the refrigerator. When the door 20 is closed, the cooling air duct communicates with the internal chambers of the door 20 to convey the cooling energy generated by the evaporator to the chambers in the door 20.

Referring to fig. 2, in particular, the door body 20 includes a door shell 21, and a first compartment 23 and a second compartment 25 formed in the door shell 21. In this embodiment, the first compartment 23 and the second compartment 25 are disposed adjacent to each other and isolated from each other, and the respective temperature settings can be performed according to the needs of the user.

Referring to fig. 3, further, the door 20 further includes a heat exchange air duct 27 disposed in the door shell 21 and communicating the first compartment 23 and the second compartment 25. In this embodiment, the heat exchange air duct 27 is connected to the first compartment 23 and the second compartment 25, i.e. a single air duct is connected to both compartments, so as to reduce the use of air ducts.

Specifically, a first air port 21a communicated with the first compartment 23, a second air port 21b communicated with the second compartment 25, and a heat exchange air port 21c communicated with the heat exchange air duct 27 are formed on the door shell 21. In this embodiment, the first air port 21a, the second air port 21b, and the heat exchange air port 21c are used for being in butt joint with the air inlet and the air outlet of the refrigeration air duct, so that the cold energy in the evaporation chamber is conveyed into the two chambers to exchange heat and refrigerate.

Specifically, the heat exchange air duct 27 has a first heat exchange port 27a opened to the first compartment 23 and a second heat exchange port 27b opened to the second compartment 25. In this embodiment, the first heat exchanging port 27a and the second heat exchanging port 27b are selectively communicated with the heat exchanging tuyere 21c, that is, the first heat exchanging port 27a and the second heat exchanging port 27b are separately communicated with the heat exchanging tuyere 21c, or the first heat exchanging port 27a and the second heat exchanging port 27b are jointly communicated with the heat exchanging tuyere 21 c. Thus, the first compartment 23 and the second compartment 25 can share one heat exchange air port 21c to communicate with the evaporation chamber, thereby reducing the number of air ports formed in the door casing 21.

Specifically, the first tuyere 21a, the first heat exchange port 27a and the heat exchange tuyere 21c form a cold air circulation of the first compartment 23, and the second tuyere 21b, the second heat exchange port 27b and the heat exchange tuyere 21c form a cold air circulation of the second compartment 25. In this embodiment, the first compartment 23 is communicated with the cooling air duct of the refrigerator through the first air opening 21a and the heat exchange air opening 21c, and the second compartment 25 is communicated with the cooling air duct of the refrigerator through the second air opening 21b and the heat exchange air opening 21c, so that the first compartment 23 and the second compartment 25 can independently enter and exit air, and the requirements of setting different temperatures of the first compartment 23 and the second compartment 25 are met.

Further, the first tuyere 21a and the first heat exchange port 27a are respectively disposed on different inner walls of the first compartment 23, and the second tuyere 21b and the second heat exchange port 27b are respectively disposed on different inner walls of the second compartment 25.

In this embodiment, because the first air port 21a and the first heat exchange port 27a are located on different inner walls of the first compartment 23, the first air port 21a and the first heat exchange port 27a are located on different planes, so that the air inlet entering the first compartment 23 and the air outlet discharging the first compartment 23 are located on different planes, and then a larger-range gas flow is formed in the first compartment 23, thereby increasing the heat exchange time of the refrigerant gas flow in the first compartment 23, and improving the refrigeration effect of the first compartment 23. On the other hand, the time from the refrigerant gas entering into the first compartment 23 to the refrigerant gas exiting from the first compartment 23 is increased relative to the case where the first tuyere 21a and the first heat exchange port 27a are on the same plane, thereby improving the refrigeration efficiency of the first compartment 23.

Similarly, the second air port 21b and the second heat exchange port 27b are respectively disposed on different inner walls of the second compartment 25, so that the second air port 21b and the second heat exchange port 27b are located on different planes, and the air inlet into the second compartment 25 and the air outlet out of the second compartment 25 are located on different planes, thereby improving the refrigeration effect of the second compartment 25 and improving the refrigeration efficiency of the second compartment 25.

In the present embodiment, the first compartment 23 and the second compartment 25 are provided at an interval in the vertical direction, and the size of the door 20 in the horizontal direction can be reduced under the condition that the area of the door 20 is equal. Of course, in some embodiments, the first compartment 23 and the second compartment 25 may be disposed at an interval in the left-right direction.

Further, the heat exchange air duct 27 is disposed between the first inner container 21d and the second inner container 21 e. In this embodiment, the heat exchange air duct 27 extends along the left-right direction and is located between the first inner container 21d and the second inner container 21e, so that the internal space of the door casing 21 is reasonably utilized, the occupied space of the heat exchange air duct 27 is reduced, and the space utilization rate of two compartments in the door casing 21 is improved.

Further, the first heat exchanging port 27a and the second heat exchanging port 27b are disposed at two opposite sides of the heat exchanging air duct 27 along the vertical direction of the box 10. In this embodiment, the first heat exchanging port 27a and the second heat exchanging port 27b are respectively disposed at the upper end and the lower end of the heat exchanging air duct 27, so that the heat exchanging air duct 27 can be conveniently communicated and butted with the first compartment 23 and the second compartment 25 while the occupied space of the heat exchanging air duct 27 is further saved.

In this embodiment, the top wall 27d of the heat exchange air duct 27 is attached to the lower wall of the first inner container 21d, so as to save the length of the connecting pipeline between the heat exchange air duct 27 and the first inner container 21 d. The bottom wall 27e of the heat exchange air duct 27 is attached to the upper wall of the second inner container 21e, so that the length of the connecting pipeline between the heat exchange air duct 27 and the second inner container 21e is saved.

Further, the first heat exchanging port 27a is disposed on the top wall 27d and extends through the first inner container 21d along the vertical direction of the box 10, and the second heat exchanging port 27b is disposed on the bottom wall 27e and extends through the second inner container 21e along the vertical direction of the box 10. In this embodiment, the extending direction of the first heat exchanging port 27a is perpendicular to the extending direction of the heat exchanging port 21c, and the extending direction of the second heat exchanging port 27b is perpendicular to the extending direction of the heat exchanging port 21c, so that the flowing time of the air flow between the heat exchanging port 21c and the first heat exchanging port 27a and between the heat exchanging port 21c and the second heat exchanging port 27b is increased, the refrigerating time of the refrigerating air flow in the two chambers is then increased, and the refrigerating efficiency is further improved.

Further, the heat exchange air duct 27 further includes a partition plate 27f disposed in the heat exchange air duct 27 and located at the same level with the heat exchange air opening 21c, and the partition plate 27f is located between the first heat exchange opening 27a and the second heat exchange opening 27 b.

In this embodiment, when the heat exchange air port 21c is used as the air outlet, the arrangement of the partition plate 27f can avoid the impact generated when the first heat exchange port 27a and the second heat exchange port 27b directly convect; when the heat exchange air port 21c is used as an air inlet, the arrangement of the partition plate 27f can prevent the air flow in the heat exchange air duct 27 from entering the first heat exchange port 27a and the second heat exchange port 27b disorderly, so that the temperatures of the first compartment 23 and the second compartment 25 can be accurately controlled, and the odor tainting between the first compartment 23 and the second compartment 25 can be avoided. The partition plate 27f and the heat exchange air port 21c are at the same horizontal height, and can exactly divide the heat exchange air duct 27 into an upper air duct cavity and a lower air duct cavity with equal volumes, and when the heat exchange air port 21c is used as an air inlet, the first heat exchange port 27a and the second heat exchange port 27b can uniformly discharge the refrigerating air flow in the heat exchange air duct 27; when the heat exchanging air port 21c is used as an air outlet, the air volume entering the heat exchanging air duct 27 through the first heat exchanging port 27a and the second heat exchanging port 27b is the same, and the condition of uneven air pressure in the two air duct cavities can not be generated when the air volume is exhausted from the heat exchanging air port 21 c.

Similarly, the second tuyere 21b, the second heat exchange port 27b, and the second communication port 29b are respectively disposed on different inner walls of the second compartment 25, and can also function to increase the heat exchange time of the refrigerant airflow in the second compartment 25, thereby improving the refrigeration effect of the second compartment 25 and improving the refrigeration efficiency of the second compartment 25.

As shown in fig. 5, when the heat exchange air port 21c is used as an air inlet to convey cold air into the heat exchange air duct 27, the first damper 27g is in a closed state, and the second damper 27h is in an open state, air in the heat exchange air duct 27 enters the second compartment 25 through the second heat exchange port 27b and directly blows the ice tray of the ice maker 30, so that the temperature of the second compartment 25 is accelerated to be lowered and ice is made, a part of air in the second compartment 25 enters the communicating air duct 29 through the second communicating port 29b and enters the first compartment 23 through the second communicating port 29a, and the air in the first compartment 23 is finally discharged out of the first compartment 23 through the first air port 21 a. Thus, the second compartment 25 having the ice maker 30 performs cooling preferentially, thereby improving ice making efficiency, and after ice making is completed, the first damper 27g can be opened again, thereby performing cooling under the same conditions in both compartments.

In some embodiments, the second tuyere 21b may be closed, so that all the gas in the second compartment 25 enters the communicating air duct 29 through the second communicating port 29b and finally enters the first compartment 23.

Of course, the first damper 27g can be opened and the second damper 27h can be closed according to the circumstances, so that the refrigeration of the first compartment 23 is accelerated, and different requirements of users can be met.

Further, the first communication port 29a and the second communication port 29b are provided on the same side of the first compartment 23 and the second compartment 25, respectively. In this embodiment, the communicating air duct 29, the first communicating port 29a and the second communicating port 29b are all located on the same side of the two chambers, so that the design of corners of the communicating air duct 29 is reduced, and the first communicating port 29a and the second communicating port 29b are convenient to communicate with each other.

Specifically, the communication air duct 29 is disposed on a side of the first inner container 21d and the second inner container 21e away from the door 20 and connected to the cabinet 10. In this embodiment, the communicating air duct 29 is disposed on one side of the door 20 away from the connecting box 10, and the first communicating opening 29a and the second communicating opening 29b are disposed on the same side of the two chambers, so that the occupied space of the communicating air duct 29 can be saved, and the space utilization rate of the two chambers in the door shell 21 can be improved.

In some embodiments, the communicating air duct 29 may also be disposed on one side of the door 20 near the connecting box 10 or other positions, and the first communicating port 29a and the second communicating port 29b may also be disposed on different sides of the two compartments.

Specifically, the heat exchange air port 21c is set as an air inlet, the first air port 21a is set as an air outlet, the horizontal height of the second communication port 29b is smaller than the horizontal height of the heat exchange air port 21c, and the horizontal height of the heat exchange air port 21c is smaller than the horizontal height of the first communication port 29 a.

In this embodiment, since the second compartment 25 is located below the first compartment 23, the cold air introduced into the second compartment 25 through the heat-exchange tuyere 21c sinks down to smoothly enter the second communication port 29b below the heat-exchange tuyere 21 c. After the second compartment 25 is completely filled with the cold air, the cold air in the communicating air duct 29 is gradually blown to the first communicating port 29a above the heat exchanging air inlet 21c, and finally enters the first compartment 23, so that the preferential cooling of the second compartment 25 can be ensured.

As shown in fig. 5, the cold energy generated in the evaporation chamber enters the second compartment 25 through the heat exchange air inlet 21c, the air flow after heat exchange in the second compartment 25 enters the communicating air duct 29 through the second communicating opening 29b, the air flow in the communicating air duct 29 is discharged through the first communicating opening 29a and enters the first compartment 23, and then the air flow after heat exchange in the first compartment 23 is finally discharged through the first air inlet 21a and returns to the evaporation chamber, and the process is repeated.

Therefore, the second compartment 25 cools before the first compartment 23, that is, the temperature decrease rate of the second compartment 25 is faster than that of the first compartment 23 under the same condition, and thus the second compartment 25 may preferably be a freezing compartment.

In other embodiments, the heat exchange air port 21c is configured as an air outlet, the first air port 21a is configured as an air inlet, and the ice maker 30 is disposed in the first compartment 23 and below the first air port 21 a. In this embodiment, the first compartment 23 cools before the second compartment 25, that is, the temperature decrease speed of the first compartment 23 is faster than that of the first compartment 23 under the same condition. Moreover, the first air opening 21a is located above the ice maker 30, and at this time, the first air opening 21a serves as an air inlet of the first compartment 23, and after cold air is input into the first compartment 23, the cold air directly flows to the ice tray due to sinking of the cold air, so that the ice making process of the ice maker 30 is accelerated, and the refrigeration efficiency of the ice maker 30 is improved.

Specifically, the communication duct 29 includes a first wall 29c facing the first inner container 21d and a second wall 29d facing the second inner container 25. In this embodiment, the communication duct 29 extends in the vertical direction of the casing 10. The first wall 29c of the communication air duct 29 is attached to the left side wall of the first inner container 21d, so that the length of a connecting pipeline between the communication air duct 29 and the first inner container 21d is saved. The second wall 29d of the communication duct 29 is attached to the left side wall of the second inner container 21e, so that the length of the connecting pipeline between the second wall 29d and the second inner container 21e is saved.

Further, the first communication port 29a is provided in the first wall 29c and extends through the first inner container 21d in the horizontal direction of the box 10, and the second communication port 29b is provided in the second wall 29d and extends through the second inner container 21e in the horizontal direction of the box 10.

In this embodiment, in the second compartment 25, the second communication port 29b extends in the horizontal direction, and the second heat exchange port 27b extends in the vertical direction, so that the extending directions of the second communication port 29b and the second heat exchange port 27b are perpendicular to each other, and thus the air intake path into the second compartment 25 and the air discharge path from the second compartment 25 are perpendicular to each other, so that the air flow in the second compartment 25 is smoother, and the air cooling efficiency is higher.

Moreover, the extending directions of the first communicating port 29a and the second communicating port 29b are perpendicular to the extending direction of the communicating air duct 29, so the extending directions of the first communicating port 29a and the second communicating port 29b are parallel to each other, and thus, the air flows entering and discharging the communicating air duct 29 are parallel to each other and perpendicular to the air flow direction in the communicating air duct 29, so that the air flow entering the first compartment 23 is enhanced, and the air cooling effect of the first compartment 23 is improved.
