In the related art, the refrigeration chamber and freezer are simultaneously refrigerated by the same refrigeration system, which can cause insufficient cooling capacity of the refrigeration chamber or freezer, resulting in poor refrigeration effect. The refrigerator provided by the embodiments of the present application can improve the above problems, the refrigerator provided by the embodiments of the present application can refrigerate the freezer and refrigeration chamber by two different refrigeration devices, so that the refrigeration chamber and freezer can be independently refrigerated, thereby improving the refrigeration effect of the refrigeration chamber and freezer.

[0037] The present application will be described below in conjunction with the drawings and specific embodiments:

[0038] Figure 1 The structure schematic diagram of the refrigerator 100 provided by the embodiments of the present application is shown, as shown in the figure, Figure 1 The refrigerator 100 provided by the embodiments of the present application is provided, the refrigerator 100 provided by the embodiments of the present application can independently refrigerate the refrigeration chamber 112 and the freezer 114, thereby improving the refrigeration effect of the refrigeration chamber 112 and the freezer 114.

[0039] Figure 2 The structure schematic diagram of the refrigerator 100 removing the door body 120 is shown, Figure 3 The cross-sectional view of A-A in Figure 2 The cross-sectional view of B-B in Figure 4 The cross-sectional view of B-B in Figure 2 The cross-sectional view of B-B in Figure 2 , Figure 3 and Figure 4As shown, in the embodiment of the present application, the refrigerator 100 comprises a cabinet 110, a door body 120, a first air duct module 130 and a second air duct module 140. The cabinet 110 has a refrigeration chamber 112 and a freezing chamber 114, and the door body 120 is rotationally connected with the cabinet 110. The first air duct module 130 is installed in the refrigeration chamber 112, and comprises a first shell 132, a first evaporator 134 and a first fan 136. The first shell 132 is connected with the cabinet 110, and has a first accommodating cavity 132a and a refrigeration air outlet 132b and a refrigeration air return port 132c in communication with the first accommodating cavity 132a. The first evaporator 134 and the first fan 136 are both installed in the first accommodating cavity 132a, and the refrigeration air outlet 132b and the refrigeration air return port 132c are both in communication with the refrigeration chamber 112.

[0040] The second air duct module 140 is installed in the freezing chamber 114, and comprises a second shell 142, a second evaporator 144 and a second fan 146. The second shell 142 is connected with the cabinet 110, and has a second accommodating cavity 142a and a freezing air outlet 142b and a freezing air return port 142c in communication with the second accommodating cavity 142a. The second evaporator 144 and the second fan 146 are both installed in the second accommodating cavity 142a, and the freezing air outlet 142b and the freezing air return port 142c are both in communication with the refrigeration chamber 112.

[0041] The cabinet 110 is the basic component of the entire refrigerator 100, is the main structure of the refrigerator 100, can provide a basis for installation of the first air duct module 130, the second air duct module 140 and other structures, so that the refrigerator 100 can become a whole, and the transportation of the refrigerator 100 can be facilitated. The cabinet 110 can comprise an outer shell 116 and an inner container, the inner container is arranged inside the outer shell 116, and the inner container and the outer shell 116 can be connected by foaming. The refrigeration chamber 112 and the freezing chamber 114 are both arranged in the inner container. In some embodiments, the inner container can comprise a refrigeration inner container 117 and a freezing inner container 118. The refrigeration chamber 112 is arranged in the refrigeration inner container 117, and the freezing chamber 114 is arranged in the freezing inner container 118.

[0042] The cabinet 110 is substantially a cuboid, and has a height direction Z, a width direction X and a depth direction Y. For the convenience of description, it is defined that, in the use state, the vertical direction is the height direction Z, the direction in which the door body 120 faces the inside of the cabinet 110 is the depth direction Y, and the width direction X, the height direction Z and the depth direction Y are all arranged perpendicularly.

[0043] The refrigerating chamber 112 and the freezing chamber 114 are two independent chambers, the first air duct module 130 is installed in the refrigerating chamber 112 for supplying air to the refrigerating chamber 112 so that the refrigerating chamber 112 can be refrigerated, and the second air duct module 140 is arranged in the freezing chamber 114 for supplying air to the freezing chamber 114 so that the freezing chamber 114 can be refrigerated.

[0044] It is easy to understand that the refrigerator 100 further comprises a compressor, a condenser and a throttle valve, the compressor, the condenser, the throttle valve, the first evaporator 134 can form one refrigeration circuit, the compressor, the condenser, the throttle valve, the second evaporator 144 can form another refrigeration circuit, that is, the first evaporator 134 and the second evaporator 144 can be connected in parallel, or the compressor, the condenser, the throttle valve, the first evaporator 134 and the second evaporator 144 can jointly form one refrigeration circuit, that is, the first evaporator 134 and the second evaporator 144 can be connected in series. In other words, the first evaporator 134 and the second evaporator 144 can be connected in series or in parallel, and the specific mode can not be limited.

[0045] The first air duct module 130 comprises the first evaporator 134 and the first fan 136, the first evaporator 134 can be connected with the condenser, so that the air in the refrigerating chamber 112 can enter the first containing cavity 132a through the refrigerating air return port 132c, and after being refrigerated by the first evaporator 134, the cold air is blown out from the refrigerating air outlet port 132b, so that the cold air can circulate in the refrigerating chamber 112.

[0046] Since the cold air can move downward under the action of gravity, the refrigerating air outlet port 132b can be arranged above the refrigerating air return port 132c, so that the cold air can flow from top to bottom and can fill the entire refrigerating chamber 112 as much as possible.

[0047] Similarly, the second air duct module 140 comprises the second evaporator 144 and the second fan 146, the second evaporator 144 can be connected with the condenser, so that the air in the freezing chamber 114 can enter the second containing cavity 142a through the freezing air return port 142c, and after being refrigerated by the second evaporator 144, the cold air is blown out from the freezing air outlet port 142b, so that the cold air can circulate in the freezing chamber 114.

[0048] Among them, the first air duct module 130 and the second air duct module 140 both have independent evaporators, so that the refrigerating chamber 112 and the freezing chamber 114 can have independent refrigeration systems, and the cold energy between the refrigerating chamber 112 and the freezing chamber 114 can not affect each other as much as possible, so that the refrigerating chamber 112 and the freezing chamber 114 can be independently refrigerated, thereby improving the refrigeration effect of the refrigerating chamber 112 and the freezing chamber 114.

[0049] In some embodiments, the refrigeration air outlet 132b and the refrigeration air return 132c are arranged on the side wall of the first shell 132. The first air duct module 130 can be arranged on one side wall of the refrigeration chamber 112 or in the middle of the refrigeration chamber 112. Whether arranged on the side wall or in the middle of the refrigeration chamber 112, the first air duct module 130 does not occupy the space behind the cabinet 110, i.e., does not occupy the size of the cabinet 110 in the depth direction Y, thereby reducing the thickness of the entire cabinet 110 and miniaturizing the entire refrigerator 100.

[0050] The side wall of the first shell 132 refers to one side of the first shell 132 along the width direction X of the cabinet 110. Arranging the refrigeration air outlet 132b and the refrigeration air return 132c on one side of the first shell 132 allows the cold air blown out of the refrigeration air outlet 132b to circulate in the refrigeration chamber 112 and then be blown out of the refrigeration air return 132c.

[0051] In some embodiments, the first air duct module 130 is arranged in the refrigeration chamber 112, which divides the refrigeration chamber 112 into a first refrigeration cavity 112a and a second refrigeration cavity 112b. The two sides of the first shell 132 are both provided with the refrigeration air outlet 132b and the refrigeration air return 132c.

[0052] Specifically, the first air duct module 130 can be arranged in the middle of the refrigeration chamber 112, so that the volumes of the first refrigeration cavity 112a and the second refrigeration cavity 112b are substantially the same, or the first air duct module 130 is arranged close to one side wall of the cabinet 110, so that the volumes of the first refrigeration cavity 112a and the second refrigeration cavity 112b can be different.

[0053] The two sides of the first shell 132 are both provided with the refrigeration air outlet 132b and the refrigeration air return 132c, i.e., the first refrigeration cavity 112a and the second refrigeration cavity 112b both have separate refrigeration air outlets 132b and refrigeration air returns 132c, so that the first refrigeration cavity 112a and the second refrigeration cavity 112b can both independently intake and return air, and the air intake and return of the first refrigeration cavity 112a and the second refrigeration cavity 112b are not affected by each other, thereby allowing the first refrigeration cavity 112a and the second refrigeration cavity 112b to work independently and improve the refrigeration effect.

[0054] In other words, for the convenience of description, the left one of the two chambers of the refrigeration chamber 112 is defined as the first refrigeration chamber 112a, and the right one is defined as the second refrigeration chamber 112b. Since the first air duct module 130 is arranged in the middle of the refrigeration chamber 112, the left side wall of the first air duct module 130 is configured as one wall surface of the first refrigeration chamber 112a, and the right side wall of the first air duct module 130 is configured as one wall surface of the second refrigeration chamber 112b. The first refrigeration chamber 112a and the second refrigeration chamber 112b are both provided with a refrigeration return air outlet 132c and a refrigeration air outlet 132b, that is, the left side wall of the first shell 132 is provided with the refrigeration return air outlet 132c and the refrigeration air outlet 132b, and the right side wall of the first shell 132 is also provided with the refrigeration return air outlet 132c and the refrigeration air outlet 132b.

[0055] For the convenience of describing the specific positions of the refrigeration air outlet 132b and the refrigeration return air outlet 132c, the following will be specifically described in one specific arrangement of the refrigeration air outlet 132b and the refrigeration return air outlet 132c in the first refrigeration chamber 112a and the second refrigeration chamber 112b, which can be similarly applied when the refrigeration air outlet 132b and the refrigeration return air outlet 132c are arranged in the other chamber. Specifically, the arrangement of the refrigeration air outlet 132b and the refrigeration return air outlet 132c in the first refrigeration chamber 112a will be specifically described, which can be similarly applied when the refrigeration air outlet 132b and the refrigeration return air outlet 132c are located in the second refrigeration chamber 112b. The following arrangements refer to the arrangement of the refrigeration air outlet 132b and the refrigeration return air outlet 132c in the first refrigeration chamber 112a.

[0056] In some embodiments, the refrigeration air outlet 132b has a plurality of refrigeration air outlets 132b arranged along the height direction Z of the first shell 132. The plurality of refrigeration air outlets 132b are arranged at different heights in the first refrigeration chamber 112a, so that the cold air can be blown to different heights of the first chamber, thereby making the cold air as evenly cooled as possible, thereby improving the refrigeration effect.

[0057] In some embodiments, the refrigeration air outlet 132b includes a first air outlet 132d and a second air outlet 132e, the first air outlet 132d is located above the second air outlet 132e, the first air outlet 132d is arranged along the depth direction Y of the cabinet 110, and the second air outlet 132e is arranged along the height direction Z of the cabinet 110.

[0058] The first air outlet 132d and the second air outlet 132e are both in a strip shape. The first air outlet 132d is arranged along the depth direction Y of the cabinet 110, that is, the length direction of the first air outlet 132d is arranged along the depth direction Y of the cabinet 110, that is, the first air outlet 132d is arranged in front of and behind the first air outlet 132d. The first air outlet 132d can cover a larger area in the depth direction Y of the cabinet 110. Since the first air outlet 132d is arranged above the second air outlet 132e, the first air outlet 132d can be arranged close to the top wall of the first refrigeration cavity 112a. The air blown out of the first air outlet 132d can be blown from the top wall of the first refrigeration cavity 112a to the bottom wall of the first refrigeration cavity 112a, so that the cold air can circulate in the entire first refrigeration cavity 112a, and the refrigeration effect in the first refrigeration cavity 112a is improved.

[0059] Similarly, since the first air outlet 132d is arranged along the depth direction Y, the first air outlet 132d has a larger coverage area in the depth direction Y of the cabinet 110, so that the cold air blown out of the first air outlet 132d can be blown to a farther place (as far as possible to the other side wall of the first refrigeration cavity 112a), so that the cold air can circulate in the entire first refrigeration cavity 112a, and the refrigeration effect in the first refrigeration cavity 112a is improved.

[0060] The second air outlet 132e is arranged along the height direction Z of the cabinet 110, that is, the length direction of the second air outlet 132e is arranged along the height direction Z of the cabinet 110, so that the second air outlet 132e can cover more areas in the height direction Z of the first refrigeration cavity 112a, and the cold air can be blown to different heights, so that the cold air can be blown to different heights as much as possible, thereby improving the refrigeration effect.

[0061] That is, the first refrigeration cavity 112a can be cooled as evenly as possible through the cooperation of the first air outlet 132d and the second air outlet 132e.

[0062] In some embodiments, the second air outlet 132e is arranged close to the rear wall of the refrigeration chamber 112. The rear wall refers to the wall surface opposite to the door body 120. Arranging the air outlet close to the rear wall of the refrigeration chamber 112 (arranging close to the rear wall of the first refrigeration cavity 112a) can reduce the loss of cold quantity during the opening of the door body 120, and can reduce the possibility of directly blowing cold air to the user, thereby improving the user experience.

[0063] Figure 5 A partial enlarged view of I in FIG. 8 is shown. Figure 4 A partial enlarged view of I in FIG. 8 is shown. Figure 5As shown, as for the air outlet of the first fan 136, the first fan 136 can be arranged above the first evaporator 134, the first fan 136 can include a first volute 136a and a first fan wheel 136b installed in the first volute 136a, a first air inlet 136c, a first refrigeration air outlet 136d and a second refrigeration air outlet 136e can be arranged on the first volute 136a, the first refrigeration air outlet 136d is in communication with the first air outlet 132d, the second refrigeration air outlet 136e is in communication with the second air outlet 132e, and the first air inlet 136c is in communication with the refrigeration air return 132c.

[0064] The above describes the arrangement position and arrangement mode of the refrigeration air outlet 132b and the refrigeration air return 132c in the first refrigeration cavity 112a, the arrangement position and arrangement mode of the refrigeration air outlet 132b and the refrigeration air return 132c in the second refrigeration cavity 112b are the same as those of the refrigeration air outlet 132b and the refrigeration air return 132c in the first refrigeration cavity 112a, and the arrangement position of the refrigeration air outlet 132b and the refrigeration air return 132c in the second refrigeration cavity 112b can refer to the arrangement position and arrangement mode of the refrigeration air outlet 132b and the refrigeration air return 132c in the first refrigeration cavity 112a, which will not be described here.

[0065] In some embodiments, the first shell 132 is foamed connected with the box body 110. In the installation process, the first fan 136 and the first evaporator 134 can be pre-installed in the first shell 132, and then the first shell 132 is pre-installed in the refrigeration liner 117, and finally the foaming liquid is filled between the outer shell 116 and the refrigeration liner 117, so that the first shell 132 is foamed connected with the refrigeration liner 117.

[0066] Specifically, as for the pre-installation mode of the first shell 132 to the refrigeration liner 117, a groove 117a can be arranged on the refrigeration liner 117, and a protrusion 137 can be arranged on the first shell 132. During pre-installation, since the refrigeration liner 117 has a certain plasticity, the first shell 132 can be pushed into the refrigeration liner 117, so that the protrusion 137 is clamped into the groove 117a, and then the pre-installation of the first shell 132 to the refrigeration liner 117 is completed.

[0067] Please refer to Figure 1 In some embodiments, the second air duct module 140 is arranged in the freezing chamber 114, and the freezing chamber 114 is divided into a first freezing cavity 114a and a second freezing cavity 114b, and the two sides of the second shell 142 are provided with a freezing air outlet 142b and a freezing air return 142c. For convenience of description, the freezing air outlet 1421b and the freezing air return 1421c in communication with the first freezing cavity 114a are defined as the first freezing air outlet 1421b and the first freezing air return 1421c, and the second freezing air outlet 1423b and the second freezing air return 1423c in communication with the second freezing cavity are defined as the second freezing air outlet 1423b and the second freezing air return 1423c.

[0068] In some embodiments, the second air duct module 140 may be disposed in the middle of the freezer compartment 114, and the freezer compartment 114 may be divided into a first freezer cavity 114a and a second freezer cavity 114b by the second air duct module 140. Alternatively, the second air duct module 140 may also be disposed on one side of the freezer compartment 114 along the width direction X of the cabinet 110. For ease of description, the example of the second air duct module 140 being disposed in the middle of the freezer compartment 114 will be used for illustration.

[0069] In some embodiments, a first refrigeration air outlet 1421b and a second refrigeration air outlet 1423b are respectively disposed on opposite sides of the second housing 142 along the width direction X of the housing 110. The first refrigeration air outlet 1421b extends to the rear wall of the first refrigeration chamber 114a, and the second refrigeration air outlet 1423b extends to the rear wall of the second refrigeration chamber 114b. The rear wall of the first refrigeration chamber refers to the wall opposite to the door, and the rear wall of the second refrigeration chamber also refers to the wall opposite to the door.

[0070] The first refrigeration air outlet 1421b is located on the side wall of the second housing 142 and extends to the rear wall of the first refrigeration cavity 114a. This allows the first refrigeration air outlet 1421b to be positioned approximately at the corner between the second housing 142 and the first refrigeration cavity 114a. The position of the first refrigeration air outlet 1421b is positioned as far behind the first refrigeration cavity 114a as possible, so that the cold air blows from back to front and from left to right, roughly diagonally, which can improve the cooling effect.

[0071] The second refrigeration air outlet 1423b is disposed on the side wall of the second housing 142 and extends to the rear wall of the second refrigeration cavity 114b, so that the second refrigeration air outlet 1423b is roughly located at the corner of the second housing 142 and the second refrigeration cavity 114b, and the position of the second refrigeration air outlet 1423b is positioned as far behind the second refrigeration cavity 114b as possible, so that the cold air blows from back to front and from right to left, roughly diagonally, which can improve the cooling effect. Figure 6 It shows Figure 2 A magnified view of a section at point II, as shown below. Figure 6 As shown, in some embodiments, the second air duct module 140 further includes a first air outlet 147, which connects the first refrigeration air outlet 1421b and the first refrigeration chamber 114a. The first air outlet 147 is installed on the rear wall of the first refrigeration chamber 114a. The first air outlet 147 can be integrally formed with the first housing 132, which facilitates the assembly of the entire first air duct. The first air outlet 147 is disposed on the rear wall of the first refrigeration chamber 114a, which facilitates the arrangement of the first air outlet 147.

[0072] In some embodiments, the first air outlet portion 147 has a first air outlet 147a extending along the width direction X of the cabinet 110. The first air outlet portion 147 can be integrally formed with the second shell 142, which can reduce the process of assembling the first air outlet portion 147 separately and facilitate installation. The first air outlet 147a is arranged along the width direction X of the cabinet 110, so that the air blown out of the first air outlet 147a can blow to the other side wall of the first freezing cavity 114a, and the cold air can flow uniformly in the first freezing cavity 114a as much as possible, thereby improving the refrigeration effect.

[0073] In some embodiments, the first air outlet 147a can extend to the second shell 142, that is, the first air outlet 147a can be directly communicated with the first freezing air outlet 1421b. The cold air blown out of the first freezing air outlet 1421b can directly flow to the first air outlet 147a and be directly blown into the first freezing cavity 114a from the first air outlet 147a, thereby reducing the air outlet path. The first air outlet 147a is arranged obliquely toward the door body 120, so that the air outlet path of the first air outlet 147a is approximately diagonal, which can increase the path in the first freezing cavity 114a, so that the cold air can blow to a farther place, thereby improving the refrigeration effect of the first freezing cavity 114a.

[0074] In some embodiments, the rear wall of the first freezing cavity 114a is provided with a first air guide surface 147b, and the first air outlet 147a extends to the first air guide surface 147b. The first air guide surface 147b can be arranged obliquely, so that the first air outlet 147a can be arranged at the corner of the second shell 142 and the rear wall of the first freezing cavity 114a, so that the cold air blown out of the first air outlet 147a can blow to a farther place, thereby improving the refrigeration effect of the first freezing cavity 114a.

[0075] Specifically, a first positioning portion 147c can be arranged in the first freezing cavity 114a, the first positioning portion 147c can abut against the second air outlet portion for fixing the second air outlet portion, and the first air guide surface 147b can be arranged on the first positioning portion 147c. Arranging the first air guide surface 147b by using the first positioning portion 147c can make the structure in the first freezing cavity 114a more compact.

[0076] As for the number of the first air outlets 147a, a plurality of first air outlets 147a can be arranged along the height direction of the cabinet 110, so that the cold air can blow to different heights of the first cavity, thereby improving the refrigeration effect.

[0077] Figure 7 A partial enlarged view of III in FIG. 10 is shown in FIG. 11. Figure 2 A partial enlarged view of III in FIG. 10 is shown in FIG. 11. Figure 7As shown, in some embodiments, the second air duct further comprises a second air outlet portion 148, the second air outlet portion 148 being in communication with the second refrigeration air outlet 1423b and the second refrigeration cavity 114b, and the second air outlet portion 148 being mounted to the rear wall of the second refrigeration cavity 114b.

[0078] In some embodiments, the second air outlet portion 148 is provided with a second air outlet opening 148a, and the second air outlet opening 148a is arranged along the width direction X of the cabinet 110.

[0079] The second air outlet portion 148 can be integrally formed with the second shell 142, which can reduce the process of assembling the second air outlet portion 148 separately and facilitate installation. The second air outlet opening 148a is arranged along the width direction X of the cabinet 110, so that the air blown out of the second air outlet opening 148a can blow towards the other side wall of the first refrigeration cavity 114a, and the cold air can flow as uniformly as possible in the second refrigeration cavity 114b, thereby improving the refrigeration effect.

[0080] In some embodiments, the second air outlet opening 148a can extend to the second shell 142, i.e., the second air outlet opening 148a can be directly in communication with the second refrigeration air outlet 1423b, and the cold air blown out of the second refrigeration air outlet 1423b can directly flow to the second air outlet opening 148a and be directly blown into the second refrigeration cavity 114b from the second air outlet opening 148a, thereby reducing the air outlet path.

[0081] The second air outlet opening 147b is arranged obliquely towards the direction of the door body 120, so that the air outlet path of the second air outlet opening 147b is approximately diagonal, which can increase the path in the second refrigeration cavity 114b, so that the cold air can be blown to a farther place, thereby improving the refrigeration effect of the first refrigeration cavity 114a.

[0082] In some embodiments, the rear wall of the second refrigeration cavity 114b is provided with a second air guide surface 148b, and the second air outlet opening 148a extends to the second air guide surface 148b. The second air guide surface 148b can be arranged obliquely, and the second air outlet opening 148a can be arranged at the corner of the second shell 142 and the rear wall of the second refrigeration cavity 114b. This can make the cold air blown out of the second air outlet opening 148a blow to a farther place, thereby improving the refrigeration effect of the second refrigeration cavity 114b.

[0083] Specifically, a second positioning portion 148c can be arranged in the second refrigeration cavity 114b, the second positioning portion 148c can abut against the second air outlet portion, for fixing the second air outlet portion, and the second air guide surface 148b can be arranged on the second positioning portion 148c. Arranging the second air guide surface 148b by using the second positioning portion 148c can make the structure in the second refrigeration cavity 114b more compact.

[0084] As for the number of second air outlets 148a, multiple outlets can be set. Multiple second air outlets 148a are set along the height of the cabinet 110 so that cold air can be blown to different heights of the second chamber, thereby improving the cooling effect.

[0085] Figure 8 It shows Figure 4 A magnified view of a section at point IV, as shown below. Figure 8 As shown, regarding the air outlet configuration of the second fan 146, the second fan 146 can be positioned above the second evaporator 144. The second fan 146 may include a second volute 146a and a second impeller 146b. The second impeller 146b is installed inside the second volute 146a. A second air inlet 146c and a first refrigeration air outlet 146d may be provided on the second volute 146a. The first refrigeration air outlet 146d may be connected to both the first air outlet 147a and the second air outlet 148a.

[0086] In some embodiments, the thickness of the door 120 is 25mm-40mm, specifically, the thickness of the door 120 can be 26mm, 28mm, 30mm, 35mm, 38mm, etc. The total thickness of the cabinet 110 and the door 120 is 450mm-600mm. The total thickness of the cabinet 110 and the door 120 can be 460mm, 480mm, 500mm, 550mm, 580mm, etc. Here, the thickness refers to the thickness in the depth direction Y of the cabinet 110, making the entire refrigerator 100 an ultra-thin refrigerator 100, capable of being embedded in narrow spaces such as sideboards and cabinets.
