As in the present invention, for convenience of description, when the refrigerator is normally used, the direction toward the ground is downward, and the direction away from the ground is upward; the direction parallel to the ground is the horizontal direction, and the direction perpendicular to the ground is the vertical direction; the side close to the user is the front side, and the side far away from the user is the rear side.

Referring to fig. 1 to 5, a refrigerator according to a preferred embodiment of the present invention may be another refrigeration apparatus using an air-cooling method.

Specifically, as shown in fig. 1, a refrigerator includes a cabinet 10 and a door 20 pivotally connected to the cabinet 10. In this embodiment, the refrigerator further includes a refrigerating air duct disposed in the case 10, and a compressor, a condenser, and an evaporator connected by pipelines, so as to cool the case 10 and the storage compartment in the door. The cold energy generated in the evaporating chamber by the evaporator can be continuously conveyed to each storage compartment from the refrigerating air duct through the evaporating fan. The door 20 is a refrigerating chamber door at an upper side of the refrigerator, thereby being convenient for a user to take. When the door 20 is closed, the cooling air duct is communicated with the internal compartments of the door 20, so as to convey the cooling energy generated by the evaporator to each compartment in the door 20.

Referring to fig. 2, in detail, the door body 20 includes a door case 21, and a first compartment 23 and a second compartment 25 formed in the door case 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.

As shown in fig. 3, the door body 20 further includes a heat exchange air duct 27 disposed in the door shell 21 and communicating with 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 also connected to the second compartment 25, i.e. a single air duct is connected to both compartments at the same time, thereby reducing the use of air ducts.

Specifically, the door shell 21 is formed with a first air port 21a communicating with the first compartment 23, a second air port 21b communicating with the second compartment 25, and a heat exchanging air port 21c communicating with the heat exchanging air duct 27. In this embodiment, the first air port 21a, the second air port 21b, and the heat exchange air port 21c are used for butt-jointing with the air inlet and the air outlet of the cooling air duct, so as to convey the cold in the evaporating chamber into the two chambers for heat exchange and cooling.

Specifically, the heat exchanging duct 27 has a first heat exchanging port 27a opened to the first compartment 23 and a second heat exchanging port 27b opened to the second compartment 25. In this embodiment, the first heat exchange port 27a and the second heat exchange port 27b may be selectively communicated with the heat exchange tuyere 21c, that is, the first heat exchange port 27a and the second heat exchange port 27b may be separately communicated with the heat exchange tuyere 21c, or the first heat exchange port 27a and the second heat exchange port 27b may be jointly communicated with the heat exchange tuyere 21c. Thus, the first compartment 23 and the second compartment 25 can communicate with the evaporation chamber by sharing one heat exchange tuyere 21c, thereby reducing the number of tuyeres provided in the door case 21.

Specifically, the first air port 21a, the first heat exchange port 27a and the heat exchange port 21c form a cold air cycle of the first compartment 23, and the second air port 21b, the second heat exchange port 27b and the heat exchange port 21c form a cold air cycle of the second compartment 25. In this embodiment, the first compartment 23 is communicated with the refrigerating air duct of the refrigerator by using the first air port 21a and the heat exchange air port 21c, and the second compartment 25 is communicated with the refrigerating air duct of the refrigerator by using the second air port 21b and the heat exchange air port 21c, so that the air inlet and outlet of the first compartment 23 and the second compartment 25 are respectively independent, and the requirement of setting different temperatures of the first compartment 23 and the second compartment 25 is met.

Further, the first air port 21a and the first heat exchanging port 27a are respectively provided on different inner walls of the first compartment 23, and the second air port 21b and the second heat exchanging port 27b are respectively provided on different inner walls of the second compartment 25.

In this embodiment, since 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 into the first compartment 23 and the air outlet out of the first compartment 23 are located on different planes, and then a larger range of air flow is formed in the first compartment 23, thereby increasing the heat exchange time of the refrigerating air flow in the first compartment 23 and improving the refrigerating effect of the first compartment 23. On the other hand, the time from the entry of the refrigerant gas into the first compartment 23 to the exit of the first compartment 23 increases in this embodiment with respect to the first tuyere 21a and the first heat exchanging port 27a being on the same plane, thereby improving the refrigerating efficiency of the first compartment 23.

Similarly, the second air port 21b and the second heat exchange port 27b are respectively arranged on different inner walls of the second chamber 25, so that the second air port 21b and the second heat exchange port 27b are positioned on different planes, and the air inlet entering the second chamber 25 and the air outlet exiting the second chamber 25 are positioned on different planes, thereby improving the refrigerating effect of the second chamber 25 and improving the refrigerating efficiency of the second chamber 25.

Specifically, the door case 21 includes a first liner 21d forming a first compartment 23 and a second liner 21e forming a second compartment 25, and the first liner 21d and the second liner 21e are disposed at intervals along the up-down direction of the case 10. In the present embodiment, the first and second compartments 23 and 25 are provided at intervals 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 the same. Of course, in some embodiments, the first compartment 23 and the second compartment 25 may be disposed at intervals along the left-right direction.

Further, the heat exchanging 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 inner space of the door shell 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 shell 21 is improved.

Further, the first heat exchanging port 27a and the second heat exchanging port 27b are disposed on opposite sides of the heat exchanging air duct 27 along the up-down direction of the case 10. In this embodiment, the first heat exchange port 27a and the second heat exchange port 27b are respectively disposed at the upper and lower ends of the heat exchange air duct 27, so that the heat exchange air duct 27 is convenient to communicate and butt with the first compartment 23 and the second compartment 25 while the space occupied by the heat exchange air duct 27 is further saved.

As shown in fig. 4, specifically, the heat exchange air duct 27 is located at the same level as the heat exchange air port 21c, and includes a side wall 27c opposite to the heat exchange air port 21c, where the heat exchange air port 21c extends in the horizontal direction of the box 10 and penetrates through the side wall 27 c.

In this embodiment, the heat exchange air duct 27 and the heat exchange air opening 21c are at the same horizontal height, and the heat exchange air opening 21c extends through the side wall 27c along the horizontal direction, so that the air flow is smoother when entering or exiting the heat exchange air duct 27 through the heat exchange air opening 21c, and the air cooling efficiency is improved.

Further, the heat exchanging air duct 27 further includes a top wall 27d opposite to the first inner container 21d, and a bottom wall 27e opposite to the second inner container 21e, and the top wall 27d and the bottom wall 27e are connected to two ends of the side wall 27c along the up-down direction of the box 10. In this embodiment, the top wall 27d of the heat exchange air duct 27 is attached to the lower wall of the first liner 21d, so as to save the length of the connecting pipeline between the heat exchange air duct 27 and the first liner 21 d. The bottom wall 27e of the heat exchange air duct 27 is attached to the upper wall of the second liner 21e, so that the length of a connecting pipeline between the heat exchange air duct 27 and the second liner 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 case 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 case 10. In this embodiment, the extending direction of the first heat exchange port 27a is perpendicular to the extending direction of the heat exchange port 21c, and the extending direction of the second heat exchange port 27b is perpendicular to the extending direction of the heat exchange port 21c, so that the flowing time of the air flow between the heat exchange port 21c and the first heat exchange port 27a and between the heat exchange port 21c and the second heat exchange port 27b is increased, the refrigerating time of the refrigerating air flow in the two chambers is further 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 at the same level as the heat exchange air port 21c, and the partition plate 27f is located between the first heat exchange port 27a and the second heat exchange port 27b.

In this embodiment, when the heat exchange air port 21c is used as the air outlet, the partition plate 27f is arranged, so that impact generated when the first heat exchange port 27a and the second heat exchange port 27b are directly convected can be avoided; when the heat exchange air port 21c is used as an air inlet, the partition plate 27f can prevent air flow in the heat exchange air duct 27 from randomly entering the first heat exchange port 27a and the second heat exchange port 27b, so that the temperature of the first compartment 23 and the second compartment 25 can be accurately controlled, and 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 positioned at the same horizontal height, so that the heat exchange air channel 27 can be just equally divided into an upper air channel cavity and a lower air channel cavity with the same volume, 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 channel 27; when the heat exchange air port 21c is used as an air outlet, the air quantity entering the heat exchange air duct 27 through the first heat exchange port 27a and the second heat exchange port 27b is the same, and the air pressures in the two air duct cavities are not uniform when the air is jointly discharged from the heat exchange air port 21c.

Further, the heat exchange air duct 27 further includes a first air door 27g disposed between the partition plate 27f and the top wall 27d, and a second air door 27h disposed between the partition plate 27f and the bottom wall 27e, the partition plate 27f has a free end close to the heat exchange air port 21c and a fixed end facing away from the heat exchange air port 21c, and the first air door 27g and the second air door 27h are both disposed at the free end of the partition plate 27 f.

In this embodiment, as shown in fig. 4, except for one free end of the partition plate 27f opposite to the side wall 27c, the other three ends are sealed and fixed with the inner wall of the heat exchange air duct 27, so that a first cavity is formed between the partition plate 27f and the top wall 27d, and a second cavity is formed between the partition plate 27f and the bottom wall 27 e. The first cavity is respectively communicated with the first heat exchange port 27a and the heat exchange port 21c, and the first air door 27g is disposed in the first cavity and located between the first heat exchange port 27a and the heat exchange port 21c, so that the air volume passing through the first heat exchange port 27a can be adjusted, and the air volume entering or exiting the first compartment 23 can be adjusted. The second cavity is respectively communicated with the second heat exchange port 27b and the heat exchange air port 21c, and the second air door 27h is arranged in the second cavity and is positioned between the second heat exchange port 27b and the heat exchange air port 21c, so that the air quantity passing through the second heat exchange port 27b can be adjusted, and the air quantity entering or exiting the second compartment 25 can be adjusted.

Further, as shown in fig. 5, the door shell 21 further includes an inner shell 21f that accommodates the first inner container 21d and the second inner container 21 e. In this embodiment, when the door 20 of the refrigerator is closed, the inner case 21f is disposed in the storage compartment of the refrigerator 10 and abuts against the inner wall of the storage compartment, so that the two compartments of the door 20 are communicated with the cooling air duct.

Specifically, the first air port 21a, the heat exchange air port 21c and the second air port 21b are all located at one side of the door 20 connected to the box 10, and are arranged on the inner shell 21f along the up-down direction of the box 10. In this embodiment, the first air port 21a, the heat exchange air port 21c and the second air port 21b are disposed on the same side of the door 20 along the vertical direction, so that when the door 20 is closed, the inner shell 21f is abutted with the inner wall of the storage compartment of the box 10, and meanwhile, the door 20 is also convenient to manufacture.

Further, the first air port 21a extends along the horizontal direction of the case 10 and penetrates the first inner container 21d, and the second air port 21b extends along the horizontal direction of the case 10 and penetrates the second inner container 21 e. In this embodiment, in the first compartment 23, the first air port 21a extends along the horizontal direction, and the first heat exchange port 27a extends along the vertical direction, so that the extending directions of the first air port 21a and the first heat exchange port 27a are perpendicular to each other, and thus, the air inlet path into the first compartment 23 and the air outlet path out of the first compartment 23 are perpendicular to each other, so that the air in the first compartment 23 flows more smoothly and the air cooling efficiency is higher. Similarly, in the second compartment 25, the second air port 21b extends in the horizontal direction, and the second heat exchanging port 27b extends in the vertical direction, so that the extending directions of the second air port 21b and the second heat exchanging port 27b are perpendicular to each other, and thus, the air inlet path into the second compartment 25 and the air outlet path out of the second compartment 25 are perpendicular to each other, so that the air in the second compartment 25 flows more smoothly and the air cooling efficiency is higher.

Further, the refrigerator further includes an ice maker 30 disposed in the first compartment 23 and/or the second compartment 25. In the present embodiment, the ice maker 30 is disposed in the door body 20, thereby facilitating the user to take ice.

In this embodiment, as shown in fig. 3, the cold energy formed in the evaporation chamber enters the heat exchange air duct 27 through the heat exchange air opening 21c, and because the first air door 27g and the second air door 27h are both in an open state, the air flow in the heat exchange air duct 27 can enter the first chamber 23 through the first heat exchange opening 27a and enter the second chamber 25 through the second heat exchange opening 27b, the air flow in the first chamber 23 after heat exchange is discharged through the first air opening 21a and returned to the evaporation chamber, and the air flow in the second chamber 25 after heat exchange is also discharged through the second air opening 21b and returned to the evaporation chamber, so that the air flow is reciprocated. The second heat exchange port 27b is located right above the ice maker 30, thereby blowing cool air directly to the ice tray, accelerating the ice making process of the ice maker 30, and improving the refrigerating efficiency of the ice maker 30.

Specifically, the heat exchange air duct 27 is disposed in the heat preservation chamber 21 h. In this embodiment, the heat exchange air duct 27 is fixed in the heat preservation chamber 21h by a preset method, and the heat preservation chamber 21h is filled with heat preservation material in the later stage.

Further, a heat insulating member 22 is provided in the heat insulating chamber 21h at the front side of the heat exchanging duct 27. In this embodiment, the heat exchange air duct 27 is located between the first door 21i and the second door 21j, so that the heat insulation material on the front side of the heat exchange air duct 27 is less, condensed water is formed on the housing 21g when cold air passes through the heat exchange air duct 27, and the heat insulation member 22 is disposed between the first door 21i and the second door 21j, so that the condensed water is prevented from forming on the housing 21g on the front side of the heat exchange air duct 27.

Specifically, the communication duct 29 has a first communication port 29a that is opened toward the first compartment 23, and a second communication port 29b that is opened toward the second compartment 25, the first heat exchange port 27a and the first communication port 29a are respectively provided on different inner walls of the first compartment 23, and the second heat exchange port 27b and the second communication port 29b are respectively provided on different inner walls of the second compartment 25.

In this embodiment, since the first air port 21a, the first heat exchange port 27a and the first communication port 29a are all located on different inner walls of the first compartment 23, the first air port 21a, the first heat exchange port 27a and the first communication port 29a are located on different planes, so that the air inlet into the first compartment 23 and the air outlet out of the first compartment 23 are located on different planes, and then a large range of air flow is formed in the first compartment 23, i.e. each corner of the first compartment 23 can cover the refrigerant air flow, thereby increasing the heat exchange time of the refrigerant air flow in the first compartment 23, improving the refrigeration effect of the first compartment 23, and simultaneously improving the refrigeration efficiency of the first compartment 23. Similarly, the second air port 21b, the second heat exchange port 27b and the second communication port 29b are respectively arranged on different inner walls of the second compartment 25, and can also play a role in increasing the heat exchange time of the refrigerating air flow in the second compartment 25, so that the refrigerating effect of the second compartment 25 is improved, and meanwhile, the refrigerating efficiency of the second compartment 25 is also improved.

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 air door 27g is in a closed state, and the second air door 27h is in an open state, air flow 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, ice is made, a part of air in the second compartment 25 enters the communication air duct 29 through the second communication port 29b, and enters the first compartment 23 through the second communication 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. In this way, the second compartment 25 having the ice maker 30 is preferentially cooled, thereby improving ice making efficiency, and after ice making is completed, the first damper 27g can be opened again, thereby realizing the cooling of the two compartments under the same condition.

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

Of course, the first air door 27g may be opened and the second air door 27h may be closed according to circumstances, so as to accelerate the cooling of the first compartment 23, and thus meet different demands of users.

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 communication duct 29, the first communication port 29a and the second communication port 29b are all located on the same side of the two compartments, so that the corner design of the communication sealing duct 29 is reduced, and mutual communication between the first communication port 29a and the second communication port 29b is facilitated.

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

In some embodiments, the communication duct 29 may be disposed on one side of the door 20 adjacent to the connecting box 10 or other positions, and the first communication port 29a and the second communication port 29b may be disposed on different sides of the connecting 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 the present embodiment, since the second compartment 25 is located below the first compartment 23, the cool air entering the second compartment 25 through the heat exchange tuyere 21c is sunk, thereby smoothly entering the second communication port 29b below the heat exchange tuyere 21c. After the second compartment 25 is completely filled with the cold air, the cold air in the communication duct 29 is gradually blown to the first communication port 29a above the heat exchange air port 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 formed in the evaporating chamber enters the second chamber 25 through the heat exchanging air port 21c, the air flow in the second chamber 25 after heat exchanging enters the communicating air duct 29 through the second communicating port 29b, the air flow in the communicating air duct 29 is discharged through the first communicating port 29a and enters the first chamber 23, and then the air flow in the first chamber 23 after heat exchanging is finally discharged through the first air port 21a and returns to the evaporating chamber, and the process is repeated.

Therefore, the second compartment 25 will cool before the first compartment 23, i.e. the cooling rate of the second compartment 25 is faster than that of the first compartment 23 under the same conditions, so that the second compartment 25 may be preferably 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 chamber 23 is cooled before the second chamber 25, i.e. the cooling speed of the first chamber 23 is faster than that of the first chamber 23 under the same condition. In addition, the first air port 21a is located above the ice maker 30, and at this time, the first air port 21a is used 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 has a first wall 29c opposite to the first liner 21d and a second wall 29d opposite to the second liner 25. In the present embodiment, the communication duct 29 extends in the up-down direction of the case 10. The first wall 29c of the communication duct 29 is attached to the left side wall of the first liner 21d, thereby saving the length of the connecting line between the communication duct 29 and the first liner 21 d. The second wall 29d of the communication air duct 29 is attached to the left side wall of the second liner 21e, so that the length of the connecting pipeline between the second wall 29d and the second liner 21e is saved.

Further, the first communication port 29a is disposed on the first wall 29c and extends through the first inner container 21d along the horizontal direction of the case 10, and the second communication port 29b is disposed on the second wall 29d and extends through the second inner container 21e along the horizontal direction of the case 10.

In this embodiment, in the second compartment 25, the second communication port 29b extends along the horizontal direction, and the second heat exchange port 27b extends along 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 inlet path into the second compartment 25 and the air outlet path out of 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 communication port 29a and the second communication port 29b are perpendicular to the extending direction of the communication duct 29, so that the extending directions of the first communication port 29a and the second communication port 29b are parallel to each other, and thus the air flows into and out of the communication duct 29 are parallel to each other and perpendicular to the air flow direction in the communication duct 29, so that the air flow into the first compartment 23 is enhanced, and the air cooling effect of the first compartment 23 is improved.
