[0002] At present, air-cooled refrigerators generally install the evaporator at the back of the box, and the installation space of the evaporator occupies part of the space of the refrigeration compartment. In order to increase the depth of the refrigeration compartment, the relevant technology proposes an air-cooled refrigerator in which the evaporator is installed below the refrigeration compartment, that is, the evaporator is installed at the bottom of the box. For this type of air-cooled refrigerator, the air duct connects the refrigeration compartment and the heat exchange chamber where the evaporator is located, and the heat exchange chamber is provided with a return air port connected to the refrigeration compartment. The air duct is provided with a fan, and the fan drives the air to flow to realize the air circulation in the circulation system formed by the refrigeration compartment, the heat exchange chamber and the air duct. However, moving the evaporator from the back of the box to the bottom of the box will cause the air supply path to become longer and the resistance along the way to increase. In particular, when the refrigerator has multiple refrigeration compartments, the air volume entering the top refrigeration compartment is relatively small. Utility Model Content

[0039] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0040] The refrigeration device provided in the embodiment of the present utility model may be a product such as a refrigerator, a freezer or a wine cabinet. The following description will be made taking the refrigeration device as a refrigerator as an example.

[0041] At present, air-cooled refrigerators are chosen by more and more users due to their advantages such as fast cooling speed and uniform cooling. Traditional air-cooled refrigerators generally set the evaporator at the back of the box, and the installation space of the evaporator occupies part of the space of the refrigeration compartment. In order to increase the depth of the refrigeration compartment, the prior art proposes an air-cooled refrigerator, in which the evaporator is set at the bottom of the refrigeration compartment, and the space for installing the evaporator is a heat exchange chamber. The heat exchange chamber is provided with a return air port connected to the refrigeration compartment, and the air-cooled refrigerator is also provided with an air duct to connect the heat exchange chamber and the refrigeration compartment. A fan is provided in the air duct, and the fan is used to drive the air flow to form a circulation system of the refrigeration compartment, the heat exchange chamber and the air duct. The refrigeration compartment is used to store items that need to be cooled, and generally multiple refrigeration compartments are provided. The refrigeration compartment can be divided into a freezing compartment, a variable temperature compartment and a refrigeration compartment according to the refrigeration temperature.

[0042] The inventors found that the above-mentioned air-cooled refrigerators are generally in the form of a single fan duct or a single fan with multiple ducts. When there are multiple refrigeration compartments, the length of the duct increases, and the air resistance along the duct increases, resulting in a decrease in the circulating air volume in the system and insufficient air volume in the refrigeration compartments far from the evaporator. In addition, the cold air needs to be transported to multiple refrigeration compartments through the duct, resulting in insufficient fine control of the air volume and poor temperature control effect. In view of the above problems, the utility model proposes a refrigerator that effectively increases the circulating air volume of the duct and the air volume of the refrigeration compartment by optimizing the layout of the duct assembly and the evaporator, and has a better temperature control effect.

[0043] Reference Figures 1 to 8 As shown, the refrigerator provided by the embodiment of the utility model includes a box body 100 , in which a storage cavity 110 and a heat exchange cavity 120 are formed. The heat exchange cavity 120 is located below the storage cavity 110 .

[0044] It should be noted that the space for storing things in the refrigerator body 100 is collectively referred to as the storage cavity 110, and the storage cavity 110 may refer to a single cavity or the sum of multiple cavities. For example, when the refrigerator has only a refrigerating compartment, the storage cavity refers to the refrigerating compartment; when the refrigerator has only a freezing compartment, the storage cavity refers to the freezing compartment; when the refrigerator has only a variable temperature compartment, the storage cavity refers to the variable temperature compartment; when the refrigerator has a refrigerating compartment and a freezing compartment, the storage cavity refers to the refrigerating compartment and the freezing compartment; when the refrigerator has a refrigerating compartment and a variable temperature compartment, the storage cavity refers to the refrigerating compartment and the variable temperature compartment; when the refrigerator has a freezing compartment and a variable temperature compartment, the storage cavity refers to the freezing compartment and the variable temperature compartment; when the refrigerator has a refrigerating compartment, a freezing compartment and a variable temperature compartment, the storage cavity refers to the refrigerating compartment, the freezing compartment and the variable temperature compartment. The space in the refrigerator body 100 for installing the evaporator 400 is called the heat exchange cavity 120.

[0045] Reference Figures 1 to 8 As shown, the refrigerator provided by the embodiment of the utility model further includes an air duct assembly 200, a first fan 500 and a second fan 510. The air duct assembly 200 is located at the rear side of the storage cavity 110. The air duct assembly 200 is provided with a first air duct 210 and a second air duct 220. The first air duct 210 and the second air duct 220 are both used to connect the heat exchange cavity 120 and the storage cavity 110. The first fan 500 is provided in the first air duct 210, and the second fan 510 is provided in the second air duct 220.

[0046] It should be noted that the air supply directions of the first air duct 210 and the second air duct 220 are independent of each other, avoiding interference resistance between the first fan 500 and the second fan 510, and the setting of the independent air duct makes the air volume of the first air duct 210 and the second air duct 220 in the same compartment close, and the temperature uniformity is better. After the cold air heat exchanged by the heat exchange cavity 120 enters the first air duct 210 and the second air duct 220, the first fan 500 drives the cold air flow in the first air duct 210, and the second fan 510 drives the cold air flow in the second air duct 220. The cold air entering the first air duct 210 is not affected by the second fan 510 in the second air duct 220, and the cold air entering the second air duct 220 is not affected by the first fan 500 in the first air duct 210. The cold air in the first air duct 210 is independent of the external environment, and the cold air in the second air duct 220 is also independent of the external environment.

[0047] It should be noted that the heat exchange chamber 120 is disposed below the storage chamber 110, and the heat exchange chamber 120 is provided with a return air port 261, which is connected to the storage chamber 110. In some embodiments, the compressor compartment is disposed below the storage chamber 110 and in front of the heat exchange chamber 120, which is a compressor compartment front arrangement. For this installation arrangement, the compressor compartment and the heat exchange chamber 120 are located at the same level, and the space of the storage chamber 110 can extend to the back of the box body 100, thereby increasing the drawer depth of the storage chamber 110. In other embodiments, the compressor compartment is arranged at the rear of the storage cavity 110. This is a rear-placed compressor compartment solution. For this installation solution, the compressor compartment and the storage cavity 110 are located at the same horizontal height. Since the compressor compartment is located at the back of the cabinet 100, part of the space at the same height as the storage cavity 110 and the compressor compartment can only extend to the front of the compressor compartment. The drawer depth of the storage cavity 110 is reduced to a certain extent, but the space at the bottom of the cabinet 100 originally used to install the compressor compartment is saved, thereby reducing the volume of the cabinet 100 of the refrigerator.

[0048] Reference Figures 1 to 8As shown, it can be understood that the first fan 500 and the second fan 510 can be centrifugal fans or axial fans. When the types of the first fan 500 and the second fan 510 are different, the structure of the air duct assembly 200 can also be changed accordingly. The following description takes the first fan 500 and the second fan 510 as centrifugal fans. The air duct assembly 200 also includes a first cover plate 230, a second cover plate 240, a third cover plate 250 and a fourth cover plate 260. The air duct assembly 200 is arranged at the rear of the box body 100, and the fourth cover plate 260, the second cover plate 240, the third cover plate 250 and the first cover plate 230 are arranged in sequence along the front and rear directions. Among them, the fourth cover plate 260 is located below the second cover plate 240; the first cover plate 230, the second cover plate 240 and the third cover plate 250 are all arranged vertically along the up and down directions; the fourth cover plate 260 is arranged obliquely and connected to the second cover plate 240. The refrigerator provided by the embodiment of the utility model further includes an evaporator 400 , and the evaporator 400 is located below the fourth cover plate 260 .

The first cover plate 230 is provided with a first groove 231 and a second groove 232, and the third cover plate 250 is covered on the first cover plate 230, so that the first groove 231 forms part of the first air duct 210 and the second groove 232 forms part of the second air duct 220, and the third cover plate 250 is provided with a first through hole and a second through hole, the first through hole is connected to the first groove 231, and the second through hole is connected to the second groove 232, and the first fan 500 is arranged in the first groove 231, and the first fan 500 corresponds to the position of the first through hole, and the second fan 510 is arranged in the second groove 232, and the second fan 510 corresponds to the position of the second through hole. The second cover plate 240 is provided with a third groove 241, and the second cover plate 240 is covered on the third cover plate 250, so that the third groove 241 forms a first air supply channel, and the first air supply channel is connected to the first through hole and the second through hole, and the first air supply channel of the second cover plate 240 guides the cold air to the first fan 500 and the second fan 510. The air in the storage cavity 110 enters the heat exchange cavity 120 through the return air port 261, and the air becomes cold air with a lower temperature after heat exchange in the evaporator 400. The cold air enters the first air supply channel, and then passes through the first through hole and the second through hole respectively, and enters the first air duct 210 and the second air duct 220.

[0050] It is understandable that if Figures 6 to 8As shown, in the refrigerator of the embodiment, at least part of the first air duct 210 is defined by the first cover plate 230 and the second cover plate 240, at least part of the second air duct 220 is defined by the second cover plate 240, the first air duct 210 and the second air duct 220 are partially stacked in the front-to-back direction, and the second air duct 220 continues to extend from the end of the first air duct 210 to the upper storage cavity 110. The first cover plate 230 is provided with a first groove 231 and a second groove 232, the third cover plate 250 is covered on the first cover plate 230, so that the second groove 232 forms part of the second air duct 220, the third cover plate 250 is provided with a first through hole and a second through hole, the first through hole is connected to the first groove 231, and the second through hole is connected to the second groove 232, the first fan 500 is arranged in the first groove, and the first fan 500 corresponds to the position of the first through hole, and the second fan 510 is arranged in the second groove 232, and the second fan 510 corresponds to the position of the second through hole. The second cover plate is provided with a third groove 241 and a fourth groove 242. The second cover plate 240 is covered on the third cover plate 250, so that the third groove 241 forms a first air supply channel, and the fourth groove 242 forms a second air supply channel. The first air supply channel is connected to the first through hole, and the second air supply channel is connected to the second through hole. The first air supply channel of the second cover plate 240 guides the cold air to the first fan 500, and the second air supply channel of the second cover plate 240 guides the cold air to the second fan 510. The air in the storage cavity 110 enters the heat exchange cavity 120 through the return air port 261. After the air is heat exchanged by the evaporator 400, it becomes cold air with a lower temperature. The cold air enters the first air supply channel and the second air supply channel respectively. The cold air enters the first air duct 210 through the first through hole in the first air supply channel, and the cold air enters the second air duct 220 through the second through hole in the second air supply channel. The second air duct 220 is located above the first air duct 210, which can be directly above or above the left and right staggered.

[0051] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 8 In the refrigerator of the embodiment, the return air outlet 261 of the heat exchange chamber 120 is located on the fourth cover plate 260, and the return air outlet 261 is provided with multiple return air outlets 261 and the return air outlets 261 are small through holes. The multiple return air outlets 261 are evenly arranged. Such a design can make the air entering the heat exchange chamber 120 more uniform and improve the uniformity of air flow.

[0052] Reference Figure 1 and Figure 2As shown, in the refrigerator of the embodiment, the storage cavity 110 includes a first chamber and a second chamber, the first chamber and the second chamber are arranged in the up-down direction, the first air duct 210 connects the first chamber and the second chamber, and the second air duct 220 connects the first chamber and the second chamber. The second chamber is provided with a first air outlet 300, a second air outlet 310, a third air outlet 320 and a fourth air outlet 330, the first air outlet 300 and the third air outlet 320 connect the first air duct 210, and the second air outlet 310 and the fourth air outlet 330 connect the second air duct 220. Two layers of drawers are arranged in the second chamber, the first air outlet 300 and the third air outlet 320 are located in the upper drawer, and the second air outlet 310 and the fourth air outlet 330 are located in the lower drawer. The first air outlet 300 is higher than the third air outlet 320, so that the air outlet area of ​​the first air outlet 300 is larger than the air outlet area of ​​the third air outlet 320.

[0053] It should be noted that the first room and the second room may also be provided with multiple layers of drawers and multiple air outlets, all of which are connected to the first air duct 210 and the second air duct 220 respectively, and all of the air outlets are arranged in multiple layers, each layer of air outlets faces a layer of drawers, the number of air outlets in each layer of drawers is more than two, and all of the air outlets in each layer of drawers are arranged at the same height. Among them, all of the air outlets are connected to the first air duct 210 and the second air duct 220 respectively, which can be understood as each air outlet is connected to the first air duct 210 or the second air duct 220 separately, and can also be understood as each air outlet is connected to the first air duct 210 and the second air duct 220.

[0054] It should be noted that, in other embodiments, multiple drawers can be arranged horizontally.

[0055] It is understandable that the first air outlet 300 and the second air outlet 310 are arranged at the same height, and the third air outlet 320 and the fourth air outlet 330 are arranged at the same height, so that the air supply distances of the air outlets of the same layer of drawers can be equal, and the air output of each air outlet can be closer, that is, the air flow in the upper drawer and the lower drawer can be more uniform, and the occurrence of air turbulence can be reduced. The first chamber can be any one of a freezing chamber, a refrigerating chamber and a variable temperature chamber, and the second chamber can also be any one of a freezing chamber, a refrigerating chamber and a variable temperature chamber.

[0056] It is understandable that the air in the second room is sucked into the heat exchange chamber 120 by the first fan 500 from the return air port 261, and the air enters the first air duct 210 and the second air duct 220 after heat exchange through the evaporator 400 in the heat exchange chamber 120. After the cold air is pressurized by the first fan 500 in the first air duct 210, a part of it is sent to the second room, and the other part is sent to the first room. After the cold air is pressurized by the second fan 510 in the second air duct 220, a part of it is sent to the second room, and the other part is sent to the first room.

[0057] It should be noted that, in other embodiments, when the storage cavity 110 includes more than three compartments, the first air duct 210 is connected to the heat exchange cavity 120 and all the compartments, and the second air duct 220 is also connected to the heat exchange cavity 120 and all the compartments, and both the first air duct 210 and the second air duct 220 supply air to all the compartments.

[0058] It should be noted that, in other embodiments, the first chamber and the second chamber can be arranged in a left-right arrangement. In this arrangement, the first air duct 210 needs to pass through the first chamber and the second chamber at the same time, and the second air duct 220 needs to pass through the first chamber and the second chamber at the same time. For example, the first air duct 210 and the second air duct 220 can be designed on the side where the first chamber is located, and extend to the side where the second chamber is located.

[0059] Reference Figure 5 and Figure 6 As shown, in the refrigerator of the embodiment, the storage cavity 110 includes a first chamber and a second chamber, the first chamber and the second chamber are arranged in the up-down direction, the first air duct 210 is only connected to the first chamber, and the second air duct 220 is only connected to the second chamber. The second chamber is provided with a first air outlet 300, a second air outlet 310, a third air outlet 320 and a fourth air outlet 330, and the first air outlet 300, the second air outlet 310, the third air outlet 320 and the fourth air outlet 330 are all connected to the first air duct 210.

The first chamber can be any one of a freezing chamber, a refrigerating chamber and a temperature-changing chamber, and the second chamber can also be any one of a freezing chamber, a refrigerating chamber and a temperature-changing chamber.

[0060] It is understandable that the air in the second room is sucked into the heat exchange chamber 120 by the first fan 500 from the return air port 261, and the air enters the first air duct 210 and the second air duct 220 after heat exchange through the evaporator 400 in the heat exchange chamber 120. The cold air is pressurized by the first fan 500 in the first air duct 210, and then sent to the second room from the first air outlet 300, the second air outlet 310, the third air outlet 320 and the fourth air outlet 330. The cold air is pressurized by the second fan 510 in the second air duct 220 and then sent to the first room above.

[0061] It should be noted that, in other embodiments, when the storage cavity 110 includes more than three compartments, all the compartments can be divided into a first part of the compartments and a second part of the compartments, the first air duct 210 is connected to the heat exchange cavity 120 and the first part of the compartments, the second air duct 220 is connected to the heat exchange cavity 120 and the second part of the compartments, the first air duct 210 independently supplies air to the first part of the compartments, and the second air duct 220 independently supplies air to the second part of the compartments.

[0062] It should be noted that, in other embodiments, the first chamber and the second chamber may be arranged side by side. In this arrangement, the first air duct 210 only needs to pass through the first chamber, and the second air duct 220 only needs to pass through the second chamber.

[0063] Reference Figure 1 and Figure 2 As shown, in the refrigerator of the embodiment, the first chamber and the second chamber are arranged in the up-down direction, the first air duct 210 and the second air duct 220 are arranged side by side in the left-right direction and symmetrically, and the first fan 500 and the second fan 510 are arranged at the same height, which can effectively improve the uniformity of air flow. Due to the existence of installation errors, the installation height of the first fan 500 and the installation height of the second fan 510 are allowed to have an error, and this situation is also regarded as the first fan 500 and the second fan 510 are arranged at the same height.

[0064] It should be noted that, in some other embodiments, the first fan 500 and the second fan 510 may be staggered, that is, the installation height of the first fan 500 and the installation height of the second fan 510 are not equal.

[0065] It should be noted that, in other embodiments, the first chamber and the second chamber may be arranged in a left-right arrangement. In this arrangement, the first air duct 210 and the second air duct 220 may be arranged side by side in the up-down direction and symmetrically to each other. The first air duct 210 supplies air to the first chamber and the second chamber at the same time, and the second air duct 220 also supplies air to the first chamber and the second chamber at the same time. The projection of the first fan 500 on the horizontal plane overlaps the projection of the second fan 510 on the horizontal plane.

[0066] Reference Figure 5 and Figure 6 As shown, in the refrigerator of the embodiment, the first chamber and the second chamber are arranged in the up-down direction, and the second fan 510 is arranged directly above the first fan 500. Such an arrangement can effectively improve the uniformity of air flow.

[0067] It should be noted that, in other embodiments, the first chamber and the second chamber are arranged in the up-down direction, the second fan 510 is located above the first fan 500, and the second fan 510 and the first fan 500 are staggered.

[0068] It should be noted that, in other embodiments, the first chamber and the second chamber may be arranged in a left-right arrangement. In this arrangement, the first air duct 210 and the second air duct 220 may be arranged side by side in the left-right direction and symmetrical to each other. The first air duct 210 is located behind the first chamber and supplies air to the first chamber alone. The second air duct 220 is located behind the second chamber and supplies air to the second chamber alone. The first fan 500 and the second fan 510 are on the same horizontal plane.

[0069] Reference Figure 2 and Figure 5 As shown, in the refrigerator of the embodiment, as the air supply distance increases, the wind speed decreases, resulting in the air volume of the second chamber being smaller than that of the first chamber. In order to improve this situation and make the air volume of the first chamber equal to that of the second chamber, the air outlet area of ​​the first air outlet 300 is designed to be larger than the air outlet area of ​​the third air outlet 320, and the air outlet area of ​​the second air outlet 310 is designed to be larger than the air outlet area of ​​the fourth air outlet 330.

[0070] It is understandable that the first air outlet 300, the second air outlet 310, the third air outlet 320 and the fourth air outlet 330 are all provided with an air guide cover. The air guide cover is tilted downward, and can guide the cold air to flow to the bottom of the storage cavity 110 to achieve rapid cooling of the items. The provision of the air guide cover reduces the situation where the cold air slowly flows downward from the top of the storage cavity 110 to the bottom, thereby reducing the energy loss of the cold air in this process, thereby improving the cooling efficiency.

[0071] It can be understood that the air in the storage cavity 110 enters the heat exchange cavity 120 from the return air port 261, and then is sent out from the first air outlet 300, the second air outlet 310, the third air outlet 320 and the fourth air outlet 330 driven by the first fan 500 and the second fan 510. The cold air hits the air guide cover and then quickly flows to the bottom of the storage cavity 110.

[0072] Reference Figures 1 to 8 As shown, the refrigerator of the embodiment, the refrigerator with dual fans and dual air ducts can effectively increase the air supply volume of the storage cavity 110, thereby improving the cooling efficiency and reducing the influence of the air supply distance on the cooling efficiency. At the same time, the dual air ducts independently supply air, and the control of the air volume is more precise, thereby improving the temperature control effect.

[0073] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
