[0067] As described in the background technology, the air film assembly and the vacuum pump only discharge the oxygen in the fresh-keeping drawer, and a nitrogen-rich and oxygen-poor gas atmosphere is formed in the fresh-keeping drawer to facilitate food preservation. The air in the refrigeration room outside the fresh-keeping drawer is still at a normal oxygen concentration. The food storage capacity is small. Moreover, the vacuum pump is arranged in the compressor compartment of the box body. When working, the operating noise of the vacuum pump can be directly transmitted to the room, which is quite noisy.

[0068] In order to solve the above technical problems, the refrigerator provided by the present application is provided with a fresh-keeping module, and the fresh-keeping module is installed in the refrigeration chamber, thereby reducing the oxygen concentration in the entire refrigeration chamber. Moreover, the fresh-keeping module includes a shell, an atmosphere-controlled membrane assembly and a vacuum pump located in the shell, so that the noise of the vacuum pump when working can be partially isolated after being blocked by the shell and the door body, and the noise is relatively small.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0076] This embodiment provides a refrigerator, which may be a direct cooling refrigerator or an air cooling refrigerator.

[0077] Figure 1 This is a front view of the refrigerator provided in the embodiment of the present application. Figure 2 This is a schematic structural diagram of a refrigerator provided in an embodiment of the present application from another angle. Figure 3 This is a schematic diagram of the structure of the refrigerator provided in an embodiment of the present application, with the door body and part of the cabinet removed.

[0078] See also Figures 1 to 3 As shown, in some embodiments, the refrigerator includes a cabinet 100, a door 200 and a refrigeration system (not shown in the figure).

[0079] In some embodiments, the box 100 includes an outer shell 110, a box liner 120, and a press chamber 130. The outer shell 110 is configured with a first accommodating cavity having a first access opening and a second access opening, and the first access opening and the second access opening are respectively arranged on two opposite sides of the outer shell 110 in the depth direction (the direction shown by the Y axis) of the box 100. The first access opening can be arranged on the front side of the outer shell 110, and the second access opening can be arranged on the rear side of the outer shell 110. The press chamber 130 is located in the outer shell 110, and the opening of the press chamber 130 is opposite to the second access opening, and the compressor and the condenser can be placed in the press chamber 130 through the second access opening and the opening.

[0080] In some embodiments, the box 120 is located inside the outer shell 110, and the box 120 forms at least one refrigeration compartment, and the box 120 has a third access opening, which is opposite to the first access opening, and items can be placed in the refrigeration compartment through the third access opening and the first access opening. A foam layer is filled between the box 120, the outer shell 110, and the press chamber 130, and the foam layer is used to insulate the refrigeration compartment, thereby ensuring the refrigeration effect in the refrigeration compartment.

[0081] There may be at least one refrigeration compartment. When the number of refrigeration compartments is one, the refrigeration compartment may be any one of a refrigeration compartment, a freezer compartment, or a temperature-changing room. When the number of refrigeration compartments is two or more, the plurality of refrigeration compartments may include at least one or more of a refrigeration compartment, a freezer compartment, or a temperature-changing room.

[0082] The door body 200 is an openable cover disposed on the front side of the box body 100 to close and open the refrigeration compartment and to take and put items in the refrigeration compartment. It should be noted that the number of the door bodies 200 can be one, two or more.

[0083] The refrigeration system may include a compressor, a condenser, a throttling device and an evaporator, wherein the compressor, the condenser, the throttling device and the evaporator are connected in series in sequence through a pipeline, and a refrigerant flows in the pipeline. The compressor and the condenser may be arranged in the compressor compartment 130, and the evaporator is arranged in the cold source chamber.

[0084] When the compressor is working, low-temperature, low-pressure refrigerant is sucked into the compressor, compressed into high-temperature, high-pressure superheated gas in the cylinder of the compressor, and then discharged into the condenser. The high-temperature, high-pressure refrigerant gas dissipates heat through the condenser, and the temperature continues to drop. It is gradually cooled to a saturated steam at normal temperature and high pressure, and further cooled to a saturated liquid. The pressure of the refrigerant remains almost unchanged during the entire condensation process. The throttling device may include a pressure reducing tube or an electronic expansion valve. In this application, the throttling device includes a pressure reducing tube as an example for description. The pressure reducing tube has low cost and is not prone to abnormal failures. The condensed refrigerant saturated liquid is throttled and depressurized through the pressure reducing tube, and the refrigerant becomes wet steam at normal temperature and low pressure. Afterwards, the wet steam at normal temperature and low pressure absorbs heat and vaporizes through the evaporator, which not only reduces the temperature of the evaporator and its surroundings, but also turns the refrigerant into a low-temperature, low-pressure gas. The evaporator cools the air in the refrigeration room to reduce the temperature of the air in the refrigeration room. The refrigerant coming out of the evaporator returns to the compressor again, and the above process is repeated so that the evaporator can continue to cool the air in the refrigeration room, thereby maintaining the refrigeration room at the set temperature.

[0085] In some embodiments, a water receiving tray is provided in the compressor chamber 130, and the water receiving tray is used to hold the defrost water of the evaporator. The defrost water can be evaporated by using the heat of the compressor.

[0086] In some embodiments, the outer shell 110 may include a first bottom plate, a first top plate, a first side plate and a first back plate, and the first bottom plate and the first top plate are arranged opposite to each other in the length direction (the direction shown by the Z axis) of the box body 100. There are two first side plates, and the two first side plates are located on both sides of the first bottom plate and the first top plate, and are connected to the first bottom plate and the first top plate. The two first side plates, the first bottom plate and the first top plate are arranged to form a first access opening. The first back plate is opposite to the first access opening, and is connected to the first top plate and the two first side plates. The first back plate, the two first side plates and the first bottom plate are arranged to form a second access opening.

[0087] In some embodiments, the first top plate and the two first side plates may be an integral structure, which can simplify the structure of the outer shell 110, improve the production efficiency of the outer shell 110, and facilitate the assembly of the box 100. Exemplarily, the first top plate and the two first side plates may be formed by bending the same plate-like material.

[0088] In some embodiments, the press chamber 130 may include a second bottom plate, a second top plate, a second back plate, and two second side plates. The second bottom plate is butted against the first bottom plate of the outer shell 110 to form the bottom surface of the box body 100. The second top plate is opposite to the second bottom plate in the length direction of the box body 100 (the direction shown by the Z axis). The two second side plates are located on both sides of the second bottom plate and the second top plate, and the second side plates are connected to the second bottom plate and the second top plate. The two second side plates and the second bottom plate and the second top plate are arranged to form an opening.

[0089] In some embodiments, the second top plate and the first bottom plate of the housing may be an integral structure, which may simplify the structure of the press chamber 130, facilitate the assembly of the refrigerator, and improve the production efficiency of the refrigerator. For example, the second top plate and the first bottom plate may be bent from the same plate-like material.

[0090] Figure 4 This is a schematic diagram of the structure of the refrigerator box and the fresh-keeping module provided in the embodiment of the present application. Figure 5 This is a schematic diagram of the structure of the fresh-keeping module in the refrigerator provided in the embodiment of the present application. Figure 6 An exploded diagram of the fresh-keeping module in the refrigerator provided in an embodiment of the present application.

[0091] See also Figures 4 to 6 As shown, in some embodiments, the refrigerator further includes a fresh-keeping module 300, which is disposed in the refrigeration room. The fresh-keeping module 300 is configured to reduce the concentration of oxygen in the refrigeration room.

[0092] The fresh-keeping module 300 includes a housing 310 , a modified atmosphere membrane assembly 320 , and a vacuum pump 330 .

[0093] The shell 310 is connected to the inner wall of the box 100, the gas-controlled membrane assembly 320 is located in the shell 310, the vacuum pump 330 is located in the shell 310, the vacuum pump 330 is connected to the gas-controlled membrane assembly 320 through a first pipe 340, and the vacuum pump 330 is connected to the outside of the refrigeration chamber through a second pipe 350.

[0094] When working, the vacuum pump 330 transports the air in the refrigeration room to the modified atmosphere membrane assembly 320, and the modified atmosphere membrane assembly 320 separates part of the oxygen, which is transported to the outside of the refrigeration room through the vacuum pump 330, and the remaining air flows into the refrigeration room. Due to the characteristics of the modified atmosphere membrane, oxygen is easier to pass through the modified atmosphere membrane than nitrogen, so after the vacuum pump 330 runs for a period of time, the oxygen content of the air inside the refrigeration room is lower than that of normal air, that is, a nitrogen-rich and oxygen-poor gas atmosphere is formed in the refrigeration room to facilitate food preservation.

[0095] The refrigerator of the present application can form a nitrogen-rich and oxygen-poor gas atmosphere in the refrigeration room to facilitate food preservation. The gas atmosphere reduces the oxygen content in the fruit and vegetable storage space, reduces the intensity of aerobic respiration of fruits and vegetables, and ensures basic respiration, preventing fruits and vegetables from performing anaerobic respiration, thereby achieving the purpose of long-term preservation of fruits and vegetables. Moreover, the gas atmosphere also contains a large amount of nitrogen and other gases, and will not reduce the cooling efficiency of items in the atmosphere-controlled fresh-keeping space, so that fruits and vegetables can be effectively stored.

[0096] It should be noted that, in order to reduce energy consumption, when the door 200 is opened, the vacuum pump 330 stops working. In some embodiments, a sensor may be provided, and the sensor and the vacuum pump 330 are both electrically connected to the controller of the refrigerator. The sensor is used to detect the opening and closing of the door 200. When the sensor detects that the door 200 is opened, the controller air vacuum pump 330 stops working.

[0097] It is understandable that in the related art, the vacuum pump 330 is arranged in the press chamber 130. Thus, during the assembly process of the cabinet 100, one person is required to perform the pipe docking, wire harness docking and wire harness arrangement of the vacuum pump 330 at the installation station of the second top plate of the press chamber 130, and one person is required to perform the pipe docking of the vacuum pump 330 at the assembly station of the box 120. However, in the assembly process provided by the present application, only one station is required to complete the pipe and wire harness docking of the vacuum pump 330. Therefore, the assembly efficiency of the refrigerator provided by the present application is relatively high.

[0098] See also Figure 3 As shown, in some embodiments of the present application, the refrigeration compartment includes a cold storage compartment, and the fresh-keeping module 300 is located in the cold storage compartment.

[0099] It is understandable that the temperature in the freezer is relatively low, the fresh-keeping module 300 is located in the freezer, and the vacuum pump 330 is easily damaged. The fresh-keeping module 300 is located in the refrigerator and has a relatively long service life.

[0100] In some embodiments of the present application, in order to reduce the impact on the accommodating space inside the refrigerating compartment, the housing 310 is connected to the inner top wall of the refrigerating compartment.

[0101] Figure 7 This is a schematic diagram of the structure of the refrigerator fresh-keeping module without the embedded box provided in the embodiment of the present application. Figure 8 This is a schematic diagram of the structure of the refrigerator fresh-keeping module without the decorative cover provided in the embodiment of the present application. Fig. 9 for Figure 7 A top view of Fig.10 A cross-sectional view of a fresh-keeping module in a refrigerator provided in an embodiment of the present application.

[0102] See also Figures 7 to 10 As shown, in some embodiments, in order to speed up the circulation of air and improve the efficiency of oxygen exhaust, the fresh-keeping module 300 also includes a fan 360 , and the fan 360 is located in the housing 310 .

[0103] In some embodiments, in order to reduce the size of the fresh-keeping module 300 along the length direction of the box body 100 , the atmosphere-controlled membrane assembly 320 is located between the fan 360 and the vacuum pump 330 along the width direction of the box body 100 .

[0104] The length direction of the box body 100 is the direction indicated by the Z axis, and the width direction of the box body 100 is the direction indicated by the X axis.

[0105] In some embodiments, along the width direction of the box body 100 , the distance d between the air outlet of the fan 360 and the side wall of the modified atmosphere membrane assembly 320 is 10-30 mm.

[0106] When the distance d between the air outlet of the fan 360 and the side wall of the atmosphere-controlled membrane assembly 320 is less than 10 mm, the air outlet of the fan 360 is closer to the side wall of the atmosphere-controlled membrane assembly 320, the wind speed is higher, and the wind collides with the side wall, generating more eddies and more noise.

[0107] When the distance d between the air outlet of the fan 360 and the side wall of the atmosphere-controlled membrane assembly 320 is greater than 30 mm, the air outlet of the fan 360 is far away from the atmosphere-controlled membrane assembly 320, and when the wind flows to the atmosphere-controlled membrane assembly 320, the flow rate is small, so the efficiency of removing oxygen is low.

[0108] It should be noted that the air inlet of the modified atmosphere membrane assembly 320 is located at the bottom and top of the modified atmosphere membrane assembly 320 along the length direction of the box 100. Air enters the modified atmosphere membrane assembly 320, and oxygen passes through the modified atmosphere membrane and flows to the outside of the refrigeration chamber through the vacuum pump 330.

[0109] See also Figures 5 to 10As shown, in some embodiments of the present application, the shell 310 includes an embedded box 311 and a mounting bracket 312, the embedded box 311 is connected to the inner wall of the box body 100, the fan 360, the atmosphere-controlled membrane assembly 320 and the vacuum pump 330 are connected to the mounting bracket 312, the mounting bracket 312 is connected to the embedded box 311, and the mounting bracket 312 forms an installation cavity with the embedded box 311 on one side facing the embedded box 311, and the fan 360, the atmosphere-controlled membrane assembly 320 and the vacuum pump 330 are located in the installation cavity.

[0110] It can be understood that the fan 360, the gas-controlled membrane assembly 320 and the vacuum pump 330 are connected to the mounting bracket 312, and then the mounting bracket 312 is connected to the embedded box 311, which makes the installation more convenient.

[0111] In some embodiments, in order to prevent the foaming material from overflowing, a sealing cotton is provided between the embedded box 311 and the box 120. A sealing sleeve is provided in the first access hole for the wire harness and the second access hole for the second pipe 350.

[0112] In some embodiments, the modified atmosphere membrane assembly 320 is detachably connected to the mounting bracket 312, so as to facilitate replacement and maintenance of the modified atmosphere membrane assembly 320. Exemplarily, the modified atmosphere membrane assembly 320 and the mounting bracket 312 can be connected by snap fastening.

[0113] In some embodiments, in order to effectively reduce the vibration noise of the fan 360 and the vacuum pump 330, the fan 360 and the vacuum pump 330 are fixed to the mounting bracket 312 by screws.

[0114] In some embodiments, in order to facilitate installation and removal of the mounting bracket 312, the mounting bracket 312 and the embedded box 311 are detachably connected. Exemplarily, the mounting bracket 312 and the embedded box 311 can be connected by a snap.

[0115] In some embodiments of the present application, in order to effectively avoid short circuit of the air path, the mounting bracket 312 is constructed with an air inlet 3121 and an air outlet 3122, the air inlet 3121 is opposite to the fan 360, and the air outlet 3122 is opposite to the vacuum pump 330, the air inlet 3121 and the air outlet 3122 are both connected to the mounting cavity and to the refrigeration room, and under the action of the fan 360 and the vacuum pump 330, the air in the refrigeration room enters the mounting cavity through the air inlet 3121, and after part of the oxygen is separated by the gas-conditioning membrane assembly 320, it flows into the refrigeration room through the air outlet 3122.

[0116] In some embodiments of the present application, in order to improve the aesthetics, the fresh-keeping module 300 further includes a decorative cover 370, which is configured with a plurality of openings, the openings being connected to the air outlet 3122, and the air inlet 3121, and the openings being connected to the refrigeration compartment. It is understandable that the decorative cover 370 can play a certain role in sound insulation.

[0117] In some embodiments of the present application, the second pipe 350 is connected to the water receiving pan in the press chamber 130 of the box body 100. In this way, the high-concentration oxygen extracted by the vacuum pump 330 through the gas-controlled membrane assembly 320 is discharged to the position of the press chamber 130 through the second pipe, and the condensed water generated during the operation of the vacuum pump 330 also drips into the water receiving pan through the second pipe.
