The inner liner can be divided into one or more, and the inner liner can be divided into refrigerating inner liner, temperature-changing inner liner, and freezing inner liner according to the function. The specific number of inner liner and function can be configured according to the use requirements of the refrigerator. In this embodiment, the inner container at least includes a bottom inner container 110, and the bottom inner container 110 can generally be a frozen inner container.

The bottom liner 110 is the inner liner at the bottom of the box body 10 and defines a storage space. The bottom inner container 110 can generally be a freezing inner container, and the bottom inner container 110 defines a storage space and a cooling chamber 100 located below the storage space. The evaporator 60 may be arranged at the center front of the cooling chamber 100 . The bottom of the box body 10 defines a press chamber 400 , and the press chamber 400 is located behind the cooling chamber 100 , that is, the press chamber 400 is located behind the lower part of the bottom inner bladder 110 . The bottom wall of the bottom inner container 110 has an inner container inclined portion 111 inclined upward from front to back at the rear of the cooling chamber 100, and the inclination angle range is set to 30° to 40°, for example, it can be set to 33°, 35°, 38°, preferably 36.7°, to provide sufficient space for the press room 400 .

There is a compressor room 400 behind the bottom of the box body 10 , the compressor 20 and the condenser 40 are arranged in the compressor room 400 at intervals along the lateral direction of the box body 10 , and the compressor room 400 is opened in front of the condenser 40 and communicates with the outside of the box body. Airflow suction port 2121. The box body 10 further includes a bottom plate 210 , side plates 250 located on both sides of the bottom plate 210 , a back plate 240 located on the rear side of the bottom plate 210 , and a press room cover plate 230 . The press compartment cover 230 together with the bottom plate 210 , the side plates 250 and the back plate 240 define the press compartment 400 . The condenser 40 is provided with a space between the rear portion and the back plate 240 , and the air flowing through the condenser 40 communicates with the area where the compressor 20 is located through the space. The airflow suction port 2121 is opened on the area of the bottom plate 210 at the front of the condenser 40 , and the airflow discharge port 2122 is opened on the area of the bottom plate 210 at the front of the compressor 20 .

The air guide assembly 320 is used to restrict the airflow direction of the cooling airflow entering the compressor chamber 400 to ensure that the airflow flows through the entire condenser 40 . The air guide assembly 320 may be a special-shaped structure, which may be determined according to the shapes of the condenser 40 and the compressor 20 , for example, may be provided as a wind baffle 220 .

The cooling fan 50 can be an axial flow fan, whose axial direction is along the left and right lateral directions of the compressor chamber 400 , so that the airflow from the condenser 40 side flows to the compressor 20 side, forming an airflow channel from the condenser 40 to the compressor 20 .

In some embodiments, the cooling fan 30 in the refrigerator is arranged on the inclined portion 111 of the inner container in the cooling chamber 100, and is configured to draw the return air into the cooling chamber 100, cool it by the evaporator 60, and promote the cooled Air flows towards the storage space.

The front side of the cooling chamber 100 is formed with at least one front return air inlet that communicates with the storage space, so that the return air flow of the storage space enters the cooling chamber 100 through the at least one front return air inlet and is cooled by the evaporator 60, so as to be cooled during cooling. Air circulation is formed between the chamber 100 and the storage space.

The evaporating dish 214 is disposed below the condenser 40 and is configured to receive the defrosting water of the refrigerator. In some embodiments, the evaporating dish 214 of the refrigerator is a substantially rectangular parallelepiped structure with an opening at the top, and has a bottom wall and four side walls extending upward from the bottom wall.

As can be appreciated by those skilled in the art, the refrigeration system of the refrigerator in this embodiment includes a throttling element (not shown in the figure), an evaporator 60 , a cooling fan 30 , a compressor 20 and a condenser connected to the compressor 20 . 40. The evaporator 60 is disposed in the cooling chamber 100 and is configured to directly or indirectly provide cooling capacity into the storage space. The refrigerator realizes the circulation of cooling air in the evaporator 60 and the storage space through the air duct system. Since the circulation structure and working principle of the refrigeration system itself are well known to those skilled in the art and are easy to implement, in order not to obscure and obscure the invention point of the present application, the refrigeration system itself will not be described in detail below.

Combined with Figure 3-Figure 9. The compressor cabin 400 is provided with a compressor 20 , a cooling fan 50 , a condenser 40 and a wind deflector 220 for installing the condenser 40 . The press cabin 400 further includes a press cabin cover plate 230 , a bottom plate 210 , a back plate 240 and side plates 250 on both sides. The compressor 20 and the condenser 40 are arranged at intervals along the lateral direction of the casing 10 in the compressor cabin 400 , and the compressor cabin 400 is provided with an airflow suction port 2121 in front of the condenser 40 that communicates with the outside of the casing 10 . When the cooling fan 50 is activated, the ambient airflow enters the compressor chamber 400 from the airflow suction port 2121 and passes through the condenser 40 to dissipate heat from the condenser 40 .

The condenser 40 is inclined upward from front to back along the depth direction of the box body 10, which can effectively utilize the air sucked in the airflow suction port 2121, so that the air can fully contact the condenser 40 and enhance the heat dissipation effect.

The wind deflector 220 is inclined upward from the rear side of the airflow suction port 2121 along the depth direction of the box body 10 from front to rear. The inclination angle of the wind deflector 220 is consistent with the inclination angle of the inclined front cover 231 , and is set so that the top of the condenser 40 is spaced from the inclined front cover 231 by a set distance. The inclined front cover 231 and the wind deflector 220 are arranged in parallel and spaced apart, and the inclination angle is the same. The condenser 40 is fixed on the air baffle 220 , so that the air entering from the airflow suction port 2121 flows through the condenser 40 along the air baffle 220 to dissipate heat from the condenser 40 . The evaporating dish 214 is disposed below the wind baffle 220 for receiving the condensed water generated by the evaporator 60 . The wind deflector 220 is inclined relative to the evaporating dish 214, so that the condenser 40 fixed on the wind deflector 220 and the condensed water in the evaporating dish 214 can ensure a certain distance, so as to avoid long-term contact with the condensed water and cause the condenser 40 to be corroded and shortened. service life. The evaporating dish 214 is disposed under the condenser 40 , and the heat generated by the condenser 40 can be used to evaporate the condensed water in the evaporating dish 214 , and at the same time, the condenser 40 can be cooled and dissipated.

The box 10 has a bottom plate 210 , and the bottom plate 210 includes a first plate portion 211 and a second plate portion 212 . The first plate portion 211 serves as the bottom wall of the compressor cabin 400 ; the second plate portion 212 extends forward from the front end of the first plate portion 211 . The first plate portion 211 is provided with an evaporating dish 214 for receiving the defrosted water from the cooling chamber 100 and a press support seat. The condenser 40 is disposed above the evaporating dish 214, and the compressor 20 is installed on the compressor support base. The second plate portion 212 is provided with an airflow intake port 2121 at the front portion of the evaporating dish 214, and the second plate portion 212 is provided with an airflow outlet port 2122 at the front portion of the press support base. The airflow suction port 2121 and the airflow exhaust port 2122 can both be set in the shape of a grille, that is, communicate with the outside of the box 10 through the ventilation holes between the grilles, so as to prevent foreign objects (such as small animals, etc.) from passing through the airflow suction port 2121 or the airflow exhaustion. The outlet 2122 enters the inside of the box 10 .

The condenser 40 is inclined upward from front to back along the depth direction of the box body 10, which can effectively utilize the air sucked in the airflow suction port 2121, so that the contact area between the air and the condenser 40 is increased, and the heat dissipation effect is enhanced. Specifically, the condenser 40 is in the shape of a flat cuboid as a whole, and is fixed on the windshield plate 220 , so that the air entering from the airflow suction port 2121 flows through the condenser 40 along the windshield plate 220 . The thickness of the condenser 40 perpendicular to the direction of the wind deflector 220 is smaller than its length from front to back and its width along the lateral direction of the box 10 , that is, the condenser 40 is thinner in the thickness direction relative to the wind deflector 220 and expands in the length direction. , making full use of the plate surface space of the wind shield 220, so that the condenser 40 can be in contact with the air in a large area, and the heat dissipation effect is enhanced. The low point of the front end of the condenser 40 can be set to be flush with the airflow suction port 2121 in the vertical direction, and the air entering from the airflow suction port 2121 can directly contact the condenser 40 to make the heat exchange more sufficient.

The condenser 40 may be a finned condenser, the fins of which are arranged in parallel along the depth direction of the box body 10, and the condenser tube of the finned condenser 40 includes a straight tube section that runs through the fins and is arranged on both sides of the fins for connecting the straight tube sections. the connecting pipe segment. The fins are arranged in parallel along the depth direction and the condenser 40 is inclined along the depth direction of the box 10 as a whole. When the air enters from the airflow suction port 2121, it can smoothly pass through the gap between the fins and fully contact and exchange heat with each fin. , greatly enhance the cooling effect. In some embodiments, the condenser 40 may also use a microchannel heat exchanger.

A plurality of fixing posts 221 are provided on the windward side of the windshield plate 220 . The top of the fixing columns 221 forms a clamping slot 2211 , and the connecting pipe section is clamped in the clamping slot 2211 to fix the finned condenser 40 to the windshield plate 220 . superior. The condenser 40 is stably installed on the wind deflector 220 through the card slot 2211, the structure is simple, and due to the special design of the card slot 2211, the installation process is simple and convenient.

The air guide assembly 320 may also include first sealing strips (not shown in the figure), the first sealing strips are arranged on both sides of the condenser 40 and are in contact with the compressor compartment cover plate 230, so as to prevent the air entering from the airflow suction port 2121 from entering from the air inlet 2121. Both sides of the condenser 40 are diffused. That is to say, the air baffle 220 is provided with first sealing strips on both sides of the condenser 40 to prevent the air entering from the airflow suction port 2121 from escaping from both sides of the condenser 40 . The first sealing strips can be arranged on both sides and the upper part of the condenser 40, so that the incoming air needs to pass through the condenser 40 completely before entering the space between the rear part of the condenser 40 and the back plate 240, so that the condenser 40 Heat dissipation is sufficient.

The refrigerator further includes a cooling fan 50 . The cooling fan 50 is disposed between the condenser 40 and the compressor 20 , and is configured to promote the formation of a cooling airflow that flows from the airflow suction port 2121 through the condenser 40 and the compressor 20 in sequence and then is discharged to the airflow outlet 2122 . In some embodiments, the refrigerator further includes a fan holder (not shown in the figures). The fan fixing frame is fixed in the compressor compartment 400 along the front and rear directions, and is located between the compressor 20 and the condenser 40 for fixing the cooling fan 50 .

When the cooling fan 50 is started, the air enters the compressor chamber 400 from the airflow suction port 2121, is guided by the air baffle 220 and evenly contacts the condenser 40 to dissipate heat from the condenser 40, and then blows through the compressor 20 through the cooling fan 50, Part of the heat generated during the operation of the compressor 20 is taken away to increase the service life of the compressor 20 , and then it is blown out from the airflow outlet 2122 in front of the compressor 20 .

A partition 213 is provided on the bottom surface of the bottom plate 210 , and is arranged to isolate the airflow suction port 2121 and the airflow discharge port 2122 . Under the action of the cooling fan 50, the external air enters the compressor chamber 400 through the airflow suction port 2121 located on one side of the partition member 213, flows through the condenser 40, the compressor 20, and finally exits from the airflow outlet located on the other side of the partition member 213. 2122 flows out to prevent the exhausted gas from directly entering the airflow suction port 2121, and does not fully exchange heat with the ambient gas, causing the gas to circulate in a small area near the box 10, reducing the heat dissipation efficiency. Specifically, the partitions 213 may be elongated, and the width may be the distance between the bottom surface of the bottom plate 210 and the ground. There are intervals between the rear end of the condenser 40 and the back plate of the compressor compartment 400, and between the side of the condenser 40 close to the compressor 20 and the cooling fan 50, which can reduce the wind resistance of the cooling airflow.

In a preferred embodiment, the section of the back plate 240 facing the condenser 40 is a continuous plate surface, that is, the plate section of the back plate 240 facing the condenser 40 has no heat dissipation holes. The applicant creatively realized that even without increasing the heat exchange area of the condenser 40, reducing the ventilation area of the compressor cabin 400 abnormally can form a better heat dissipation airflow path, and still achieve a better heat dissipation effect. . In the preferred solution of the present invention, the applicant breaks through the conventional design idea, designs the plate section corresponding to the back plate 240 and the condenser 40 as a continuous plate surface, and seals the cooling airflow entering the compressor chamber 400 at the condenser 40, so that the The ambient air entering from the airflow suction port 2121 is more concentrated at the condenser 40, which ensures the heat exchange uniformity of each condensing section of the condenser 40, and is conducive to the formation of a better heat dissipation airflow path, which can also achieve better heat dissipation. heat radiation. In addition, since the plate section of the back plate 240 facing the condenser 40 is a continuous plate surface and does not have air inlet holes, it is avoided that both the outlet air and the inlet air are concentrated at the rear of the compressor chamber 400 in the conventional design and blow out from the compressor chamber 400 The generated hot air is not cooled by the ambient air in time and enters the compressor chamber 400 again, which adversely affects the heat exchange of the condenser 40 , thereby ensuring the heat exchange efficiency of the condenser 40 .

The compressor compartment 400 of the refrigerator in this embodiment is disposed behind the bottom of the box body 10 . The compressor cabin 400 is provided with a compressor 20 , a cooling fan 50 , a wind baffle 220 and a condenser 40 . The wind deflector 220 is inclined along the depth direction of the box body 10 , and the condenser 40 is fixed on the wind deflector 220 . An air intake port 2121 is opened in front of the wind deflector 220 . When the cooling fan 50 is started, the air enters the compressor chamber 400 from the air intake, fully contacts the condenser 40 and enters the rear space of the condenser 40, and is then introduced into the compressor 20 through the cooling fan 50, thereby taking the compressor 20 away. The heat generated by the operation is exhausted from the compressor chamber 400 via the airflow outlet 2122 . The inclined arrangement of the air baffle 220 and the condenser 40 increases the contact area between the airflow and the condenser 40, so that the condenser 40 can fully dissipate heat, thereby optimizing the heat dissipation performance of the refrigerator and improving the heat dissipation structure.

In another embodiment as shown in Figures 10-17. In this embodiment, the shape and fixing structure of the condenser 40 and the structure of the corresponding air guide assembly 320 are different from those in the previous embodiment.

The condenser 40 in this embodiment is in the shape of a flat cuboid as a whole, is installed horizontally in the compressor chamber 400 , and is horizontally spaced from the compressor 20 along the lateral direction of the casing 10 . The cooling fins 216 of the condenser 40 may extend along the depth direction of the casing 10 . The compressor chamber 400 is provided with an air intake 2121 in front of the condenser 40 and communicated with the outside of the casing 10 , so that the air sucked from the air intake flows along the gaps between the cooling fins 216 .
