Description

Technical Field

[0001] The present application relates to the field of refrigeration equipment, and in particular to a refrigerator. Background Art

[0002] Catalyst blocks are commonly used in refrigeration equipment such as refrigerators, freezers or wine cabinets. They are generally installed in the air duct formed by the air duct plate and the inner wall of the box through an installation structure. After the air flow in the refrigeration chamber enters the air duct through the return air port, it can be filtered and sterilized under the catalytic action of the catalyst block, and dissipate heat and cool down under the action of the evaporator. The treated airflow flows into the refrigeration chamber again to preserve the food placed in the refrigeration chamber.

[0003] In the related art, since the wall surface of the air duct plate made by the blister process is relatively thin, the stability of the traditional installation structure after being fixed on the blister air duct plate is poor. After the catalyst block falls off the blister air duct plate, it will slide along the air duct and fall to the bottom of the refrigeration chamber after passing through the return air port, so that the airflow circulating through the air duct cannot react with the catalyst block, affecting the filtration and sterilization of the airflow and the preservation of food. Some solutions try to integrate the installation box and the installation cover directly into the blister air duct plate during the blister process to improve the stability of the catalyst block installation.

[0004] However, in the actual process flow, due to the poor control accuracy of the structural surface by the blister forming process, there are large processing errors in the tiny structures on the parts (such as the clamping ribs on the mounting box body and the mounting cover body), which makes it impossible for the mounting box body and the mounting cover body manufactured by the mold to be tightly connected to form a stable space for installing the catalyst block. This will also cause the catalyst block and the blister forming air duct plate to have poor stability after installation. Utility Model Content

[0005] The utility model aims to provide a refrigerator, aiming to solve the problem that the catalyst block is installed on the blister air duct plate with poor stability.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] In the first aspect of the present application, a refrigerator is provided, which may include a box body, a first blister air duct plate and a mounting assembly. The box body may include a box liner, the interior of which forms a refrigeration chamber; the first blister air duct plate is spaced apart from the inner wall surface of the box liner to form a first air duct, and the first air duct is connected to the refrigeration chamber; the mounting assembly includes a first mounting member and a second mounting member, the first mounting member is arranged on a side of the first blister air duct plate close to the first air duct, and the first mounting member and the first blister air duct plate enclose a first accommodating cavity connected to the first air duct, the first accommodating cavity is used to install a first catalyst block, and the second mounting member is arranged on a side of the first blister air duct plate away from the first air duct. Among them, one of the first mounting member and the second mounting member is provided with a connecting portion, the connecting portion passes through the first blister air duct plate, and is connected to the other of the first mounting member and the second mounting member, so that the first mounting member and the second mounting member are clamped on opposite sides of the first blister air duct plate.

[0008] In this way, since the mounting assembly in the present application is not directly connected to the first blister air duct plate, the force fulcrum is no longer located on the first blister air duct plate, but on the first mounting member and the second mounting member. After the first mounting member and the second mounting member are clamped on opposite sides of the first blister air duct plate, both surfaces of the first blister air duct plate will be subjected to positive pressure and friction, wherein the positive pressures are equal in magnitude and opposite in direction, so the first blister air duct plate is only subjected to the vertical downward friction force exerted by the first mounting member and the second mounting member.

[0009] In the traditional technical solution, since the force fulcrum is located on the first blister air duct plate, after the installation component is connected to the first blister air duct plate, the local surface of the first blister air duct plate will be subjected to a pulling force along the downward direction. For a thin-walled structure, this pulling force can separate the part of the first blister air duct plate near the force fulcrum from the whole, thereby damaging the first blister air duct plate.

[0010] It can be understood that the present application improves the position and force form of the force fulcrum when the installation component and the first blister air duct plate are connected, reduces the damage of the installation component to the first blister air duct plate, and allows the installation component to be stably clamped on the surfaces of the first blister air duct plate on opposite sides, one side of the first catalyst block located in the first mounting piece abuts against the first mounting piece, and the other side abuts against the first blister air duct plate, so that it can be stably connected to the first blister air duct plate, so that the airflow can be filtered and sterilized under the catalytic action of the first catalyst block when flowing through the first air duct, thereby ensuring the preservation effect of food in the refrigeration chamber.

[0011] In addition, after the first mounting member and the second mounting member are clamped on opposite sides of the first blister air duct plate, the structural strength of the first blister air duct plate at the connection position is also improved, thereby further ensuring the connection stability between the first catalyst block and the first blister air duct plate.

[0012] In some embodiments of the present application, the connecting portion may include a plurality of hooks, which are arranged on the first mounting member, and the second mounting member is provided with a plurality of hook holes. Each hook passes through the corresponding hook holes on the first blister air duct plate and the second mounting member in turn, and abuts against the side of the second mounting member facing away from the first blister air duct plate.

[0013] In some embodiments of the present application, the first mounting member and the second mounting member are integrally formed, the first mounting member and the second mounting member have a common edge, and the first mounting member rotates relative to the second mounting member with the common edge as a rotation axis.

[0015] In some embodiments of the present application, the refrigeration chamber is located on a side of the second clamping surface away from the first accommodating cavity, and a plurality of second vents are provided on the second clamping surface, and the second vents connect the first accommodating cavity and the refrigeration chamber.

[0016] In some embodiments of the present application, the second mounting member and the first blister air duct plate enclose a second accommodating cavity connected to the first accommodating cavity, and the second accommodating cavity is used to install the second catalyst block. The second mounting member may include a third clamping surface, and when the first mounting member is connected to the second mounting member, the second clamping surface is used to abut one side of the second catalyst block, and the third clamping surface is used to abut the other side of the second catalyst block.

[0017] In some embodiments of the present application, the second mounting member is located in the refrigeration chamber, and a plurality of third ventilation holes are provided on the third clamping surface, and the third ventilation holes communicate with the second accommodating cavity and the refrigeration chamber.

[0018] In some embodiments of the present application, the refrigerator may also include a second blister air duct plate and a heat exchanger, the second blister air duct plate is connected to one end of the first blister air duct plate away from the catalyst block, and the second blister air duct plate and the box body form a second air duct, the second air duct is connected to the first air duct, the heat exchanger is arranged in the second air duct, and the mounting assembly is located below the heat exchanger.

[0019] In a second aspect of the present application, a refrigerator is provided, comprising a housing, a first blister air duct plate and a mounting assembly, the housing being used to form a refrigeration chamber, the first blister air duct plate being used to form a first air duct, the first air duct being connected to the refrigeration chamber, the mounting assembly comprising a first mounting member and a second mounting member, the first mounting member being used to form a first accommodating cavity connected to the first air duct, the first accommodating cavity being used to install a first catalyst block, the second mounting member being arranged on a side of the first blister air duct plate facing away from the first air duct, and the first mounting member and the second mounting member being capable of being clamped on the first blister air duct plate.

[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

If the specific posture changes, the directional indication will also change accordingly.

[0050] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0051] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection.

[0055] Catalyst blocks are commonly used in refrigeration equipment such as refrigerators, freezers or wine cabinets. They are generally installed in the air duct formed by the air duct plate and the inner wall of the box through an installation structure. After the air flow in the refrigeration chamber enters the air duct through the return air port, it can be filtered and sterilized under the catalytic action of the catalyst block, and dissipate heat and cool down under the action of the evaporator. The treated airflow flows into the refrigeration chamber again to preserve the food placed in the refrigeration chamber.

[0056] In the related art, since the wall surface of the air duct plate made by the blister process is relatively thin (1mm-3mm), the traditional mounting structure connected to the thin-walled structure is prone to loosening. After the catalyst block falls off the blister air duct plate, it will slide along the air duct and fall to the bottom of the refrigeration chamber after passing through the return air port, making it impossible for the airflow circulating through the air duct to catalyze the reaction with the catalyst block, affecting the filtration and sterilization of the airflow and the preservation of food.

[0057] Based on this, the present application provides a refrigerator that can improve the connection strength between the catalyst block and the blister air duct plate, thereby ensuring the preservation effect of food in the refrigerator. The structure and effect of the refrigerator provided by the present application will be described in detail below in conjunction with the drawings of the specification.

[0058] Figure 1 FIG. 1 shows one of the overall structural diagrams of the refrigerator provided in the embodiment of the present application, referring to FIG. Figure 1 The refrigerator 1 may include a box body 10 , which may include an outer shell 11 and a box liner 12 disposed in the outer shell 11 , and a refrigeration chamber 13 is formed inside the box liner 12 .

[0059] It should be noted that the refrigeration chamber 13 can be a refrigerating chamber, a variable temperature chamber or a freezing chamber. The temperature of the refrigerating chamber is generally between 2°C and 8°C, which can keep the food in a refrigerated state; the temperature of the freezing chamber is generally between -14°C and -26°C, which can keep the food in a frozen state; the temperature of the variable temperature chamber is generally adjustable between 5°C and -7°C, or can be directly adjusted to -18°C for use as a freezing chamber.

[0060] Continue reading Figure 1 In some embodiments of the present application, the box body 10 is further provided with an opening 14 communicating with the refrigeration chamber 13 , and the refrigeration chamber 13 is provided with a plurality of storage drawers 15 arranged along the height direction of the box body 10 .

[0061] In this way, the user can place different articles in different storage drawers 15 through the openings 14 according to his / her own use requirements, or take articles out of the storage drawer 15 through the openings 14 .

[0062] Figure 2 The second schematic diagram of the overall structure of the refrigerator provided in the embodiment of the present application is shown. Figure 3 Shows Figure 2 Schematic diagram of the cross-section structure at position AA, Figure 4 A schematic diagram showing the position of the installation assembly provided in an embodiment of the present application in a box body is shown. Figure 5 Shows Figure 4 The enlarged structural diagram at position B, the following part will explain the structure of the air duct assembly 20, the position of the mounting assembly 30 and the flow direction of the airflow in the present application.

[0063] In some embodiments of the present application, Figure 3 As shown, the refrigerator 1 may include an air duct assembly 20, which is spaced apart from the inner wall surface of the box 12 to form an air flow channel 21, and the upper and lower ends of the air flow channel 21 can be connected to the refrigeration chamber 13, so that the air flow can circulate between the refrigeration chamber 13 and the air flow channel 21.

[0064] Specifically, in some embodiments of the present application, Figure 3 and Figure 4 As shown, the air duct assembly 20 may include a first blister air duct plate 22 , which is spaced apart from the box 12 to form a first air duct 211 , and the first air duct 211 has a return air port 212 , which can connect the first air duct 211 and the refrigeration chamber 13 .

[0065] Among them, Figure 5As shown, the installation component 30 is disposed in the first air duct 211, so that the airflow in the refrigeration chamber 13 can first enter the first air duct 211 through the return air port 212, and react with the catalyst block in the installation component 30 to complete the filtering and sterilization stage of the airflow.

[0066] In some embodiments of the present application, Figure 3 and Figure 4 As shown, the air duct assembly 20 may further include a second blister air duct plate 23 , which is spaced apart from the box 12 to form a second air duct 213 , and the second air duct 213 and the first air duct 211 together constitute the air flow channel 21 .

[0067] Combined with reference Figure 3 and Figure 5 The heat exchanger 40 of the present application is arranged in the second air duct 213. In this way, the airflow that completes the filtering and sterilization stage in the first air duct 211 will continue to flow along the second air duct 213. During this process, since the refrigerant in the heat exchange tube 41 needs to absorb heat in the process of changing from liquid to gas, the airflow can exchange heat with the heat exchange tube 41 through heat convection, heat conduction and heat radiation when flowing through the heat exchange tube 41, and transfer the heat to the heat exchange tube 41 and the refrigerant in the heat exchange tube 41, so that the temperature of the airflow after the heat exchange is reduced, completing the cooling stage of the airflow.

[0068] It is understandable that the catalyst block may be partially crushed and fall off when exposed to humid air for a long time. In the structure of a traditional refrigerator, the catalyst block is usually arranged at the air inlet above the refrigeration chamber 13, that is, above the heat exchanger 40, resulting in the damp catalyst block debris falling on the heat exchanger 40, causing corrosion damage to the heat exchanger 40. However, the present application arranges the mounting assembly 30 and the catalyst block in the first air duct 211 below, and the heat exchanger 40 in the second air duct 213 above, that is, the mounting assembly 30 and the catalyst block are arranged below the heat exchanger 40, thereby effectively preventing the damp catalyst block debris from falling on the heat exchanger 40, causing corrosion damage to the heat exchanger 40.

[0069] The following section will provide a detailed description of the specific structure of the installation assembly 30 provided in the present application.

[0070] Figure 6 One of the structural schematic diagrams of the installation assembly provided in the embodiment of the present application is shown, Figure 7 A schematic diagram showing the connection between the mounting assembly and the air duct assembly provided in an embodiment of the present application is shown. Figure 8 for Figure 7 The enlarged structural diagram at position C, combined with reference Figure 6 , Figure 7 and Figure 8In some embodiments of the present application, the mounting assembly 30 may include a first mounting member 31, which is disposed on a side of the first blister air duct plate 22 close to the first air duct 211, and the first mounting member 31 and the first blister air duct plate 22 enclose a first accommodating cavity 311 connected to the first air duct 211, and the first accommodating cavity 311 can be used to place the first catalyst block.

[0071] In some embodiments of the present application, the mounting assembly 30 may further include a second mounting member 32 , and the second mounting member 32 is disposed on a side of the first blister air duct plate 22 away from the first air duct 211 .

[0072] In some embodiments of the present application, a plurality of connecting portions 312 are provided on the first mounting member 31, each connecting portion 312 passes through the first blister air duct plate 22 and is connected to the second mounting member 32, so that the first mounting member 31 and the second mounting member 32 are clamped on opposite sides of the first blister air duct plate 22.

[0073] It should be noted that the second mounting member 32 may be Figure 6 The single plate structure shown can also be Fig. 9 The multiple separated flat plate structures shown only need to be clamped on the other side of the first blister air duct plate 22 and provide force fulcrums for the multiple connecting parts 312 .

[0074] It should also be noted that the connecting portion 312 may be Figure 6 The arrangement shown is on the first mounting member 31, and may also be as follows Fig.10 As shown, the second mounting member 32 is arranged. As long as the connecting portion 312 can pass through the first blister air duct plate 22, the first mounting member 31 and the second mounting member 32 are connected together, and the first blister air duct plate 22 is sandwiched in the middle.

[0075] In this way, since the mounting assembly 30 in the present application is not directly connected to the first blister air duct plate 22, the force fulcrum is no longer located on the first blister air duct plate 22, but is located on the first mounting member 31 and the second mounting member 32. After the first mounting member 31 and the second mounting member 32 are clamped on the opposite sides of the first blister air duct plate 22, both surfaces of the first blister air duct plate 22 will be subjected to positive pressure and friction, wherein the positive pressures are equal in magnitude and opposite in direction, so the first blister air duct plate 22 is only subjected to the vertical downward friction force exerted by the first mounting member 31 and the second mounting member 32.

[0076] In the conventional technical solution, since the force fulcrum is located on the first blister air duct plate 22, after the mounting assembly 30 is connected to the first blister air duct plate 22, the local surface of the first blister air duct plate 22 will be subjected to a pulling force along the downward diagonal direction. For a thin-walled structure, the pulling force can separate the portion of the first blister air duct plate 22 near the force fulcrum from the whole, thereby damaging the first blister air duct plate 22.

[0077] It can be understood that the present application improves the position and force form of the force fulcrum when the installation component 30 and the first blister air duct plate 22 are connected, reduces the damage of the installation component 30 to the first blister air duct plate 22, and allows the installation component 30 to be stably clamped on the first blister air duct plate 22, and one side of the first catalyst block located in the first mounting member 31 abuts against the first mounting member 31, and the other side abuts against the first blister air duct plate 22, so that it can be stably connected to the first blister air duct plate 22.

[0078] In addition, after the first mounting member 31 and the second mounting member 32 are clamped on opposite sides of the first blister air duct plate 22, the structural strength of the first blister air duct plate 22 at the connection position is also improved, thereby further ensuring the connection stability between the first catalyst block and the first blister air duct plate 22.

[0079] Fig.11 FIG. 4 shows a fourth structural diagram of the installation assembly provided in an embodiment of the present application, referring to FIG. Fig.11 In some embodiments of the present application, the connecting portion 312 may include a hook 3120, and the two hooks 3120 are respectively arranged on opposite sides of the first mounting member 31 along the first direction F1. Correspondingly, two holes 321 are arranged on the second mounting member 32 along the first direction F1, and each hook 3120 passes through the first blister air duct plate 22 (such as Figure 8 As shown), the corresponding card hole 321 on the second mounting member 32, and then abuts against the side of the second mounting member 32 away from the first blister air duct plate 22.

[0080] In this way, the hook 3120 can be hooked on the back side of the second mounting member 32 after passing through the hole 321. The second mounting member 32 provides a stable force fulcrum for the hook 3120, so that the second mounting member 32 can be tightly pressed against the first blister air duct plate 22, so that the first mounting member 31 and the second mounting member 32 can form a stable clamp on the first blister air duct plate 22.

[0081] Fig.12 The fifth structural diagram of the installation assembly provided in the embodiment of the present application is shown. Fig.12 In some embodiments of the present application, the first mounting member 31 and the second mounting member 32 can be configured to be integrally formed, and the first mounting member 31 can be rotatably disposed on the second mounting member 32 .

[0082] It should be noted that the integral molding of the first mounting member 31 and the second mounting member 32 can be carried out by injection molding. Compared with the vacuum forming process, the injection molding process can better control the processing accuracy of the tiny structures on the components (such as the hook 3120, the hole 321, etc.), so that the first mounting member 31 and the second mounting member 32 have better clamping strength.

[0083] It should also be noted that a hook 3120 can be set on the first mounting member 31 and a hole 321 can be set on the second mounting member 32, or a hole 321 can be set on the first mounting member 31 and a hook 3120 can be set on the second mounting member 32, as long as the hook 3120 and the hole 321 can correspond one to one.

[0084] In this way, in the actual assembly process, the operator only needs to put the first catalyst block into the first accommodating cavity 311 of the first mounting member 31, and then move the first mounting member 31 closer to one side of the first blister air duct plate 22, and finally flip the second mounting member 32 until the hook 3120 passes through the first blister air duct plate 22 and cooperates with the hook hole 321, so that the first mounting member 31 and the second mounting member 32 can be stably clamped on the first blister air duct plate 22, thereby realizing a stable connection between the first catalyst block and the first blister air duct plate 22.

[0085] In this way, the assembly process can be simplified and the assembly efficiency can be improved, and the connection strength between the first mounting member 31 and the second mounting member 32 and between the mounting assembly 30 and the air duct assembly 20 can be enhanced.

[0086] Continue reading Fig.12 In some embodiments of the present application, the first mounting member 31 and the second mounting member 32 have a common edge 313, the first mounting member 31 rotates relative to the second mounting member 32 with the common edge 313 as the rotation axis, and the hook 3120 is arranged at one end of the second mounting member 32 away from the common edge 313.

[0087] It is understandable that if the hook 3120 is arranged near the common edge 313, then although the first mounting member 31 and the second mounting member 32 near the hook 3120 can fit tightly, there will be a large gap between the first mounting member 31 and the second mounting member 32 at the end away from the common edge 313, so that the first mounting member 31 and the second mounting member 32 cannot form a stable clamping of the first blister air duct plate 22. However, setting the hook 3120 at the end away from the common edge 313 is conducive to promoting the close fit of the two ends and the middle part of the first mounting member 31 and the second mounting member 32, thereby forming a stable clamping of the first blister air duct plate 22.

[0088] Fig.13FIG. 1 shows one of the connection diagrams of the mounting assembly and the first blister air duct plate provided in the embodiment of the present application, and FIG. Figure 5 and Fig.13 In some embodiments of the present application, the first mounting member 31 may include a first clamping surface 314 , on which a plurality of first vent holes 315 are formed, and the first vent holes 315 connect the first accommodating cavity 311 and the first air duct 211 .

[0089] In some embodiments of the present application, the first blister air duct plate 22 has a second clamping surface 220. When the first mounting member 31 is connected to the second mounting member 32, the first clamping surface 314 abuts against one side of the first catalyst block, and the second clamping surface 220 abuts against the other side of the first catalyst block.

[0090] It should be noted that the positions of the plurality of first vent holes 315 can be arranged at equal intervals along the second direction F2 on the first clamping surface 314, or can be arranged at unequal intervals, and the first vent holes 315 can be rectangular or circular. When the plurality of first vent holes 315 are arranged at equal intervals on the first clamping surface 314, the airflow in the first air duct 211 can enter the first accommodating cavity 311 relatively evenly along the plurality of first vent holes 315, and fully interact with different positions of the first catalyst block located in the first accommodating cavity 311, which is conducive to improving the filtering and sterilization effect of the first catalyst block.

[0091] Fig.14 The structure diagram of the first blister air duct plate provided in the embodiment of the present application is shown. Fig.15 for Fig.14 A schematic diagram of the enlarged structure at position D, Fig.16 The schematic diagram of the airflow direction in the refrigerator 1 provided in the embodiment of the present application is shown in FIG. Fig.14 , Fig.15 and Fig.16 In some embodiments of the present application, a plurality of second vent holes 221 may be provided on the second clamping surface 220, which are used to connect the first accommodating cavity 311 and the refrigeration chamber 13 respectively located on both sides of the first blister air duct plate 22. The specific position and structure of the second vent holes 221 on the second clamping surface 220 are similar to those of the first vent holes 315, and are not described again here.

[0092] The second clamping surface 220 is further provided with a connecting hole 222 through which the hook 3120 can pass. The specific position of the connecting hole 222 can be set according to the position of the hook 3120 on the first mounting member 31 or the second mounting member 32 .

[0093] In this way, the refrigerator 1 provided in the present application can form two airflow cycles, specifically:

[0094] In the first air flow cycle, the air flow direction is refrigeration chamber 13 → air return port 212 → first air duct 211 → first vent hole 315 → first catalyst block → first vent hole 315 → second air duct 213 → refrigeration chamber 13 .

[0095] In the second air flow cycle, the air flow direction is refrigeration chamber 13 → air return port 212 → first air duct 211 → first vent hole 315 → first catalyst block → second vent hole 221 → refrigeration chamber 13 in sequence.

[0096] It can be understood that since the traditional structure only has the above-mentioned first airflow circulation mode, and the present application constitutes an airflow dual circulation mode, and compared with the first airflow circulation, the flow length of the second airflow circulation is shorter, therefore, the number of cycles in the same time period is more, and the airflow can more fully catalytically react with the first catalyst block during the circulation process, thereby further enhancing the antibacterial, purification and deodorization effects of the refrigerator 1.

[0097] Fig.17 The second schematic diagram of the connection between the installation assembly provided in the embodiment of the present application and the first blister air duct plate is shown, see Fig.17 In some embodiments of the present application, the second mounting member 32 and the first blister air duct plate 22 enclose a second accommodating cavity 322 that is connected to the first accommodating cavity 311, so that the second accommodating cavity 322 can be used to install a second catalyst block, one side of the second catalyst block abuts against the second clamping surface 220 on the first blister air duct plate 22, and the other side abuts against the third clamping surface 323 of the second mounting member 32.

[0098] It can be understood that the installation component 30 forms two accommodating cavities on both sides of the first blister air duct plate 22. On the one hand, the installation component 30 can carry more catalyst blocks in a limited space to improve the filtering and sterilization effect of the airflow. On the other hand, after the catalyst blocks are installed on both sides of the first blister air duct plate 22, the forces on the two surfaces of the first blister air duct plate 22 can be relatively balanced, which is beneficial to reduce the damage to the first blister air duct plate 22 and maintain the structural stability of the first blister air duct plate 22.

[0099] Fig.18 The third schematic diagram of the connection between the installation assembly provided by the present application and the first blister air duct plate is shown. Fig.19 for Fig.18 Schematic diagram of the cross-section structure at position BB, Fig. 20 for Fig.19 The enlarged structural diagram at position E, combined with reference Fig.16 , Figure 18-Figure 20In some embodiments of the present application, a plurality of third vent holes 324 are provided on the third clamping surface 323, and the third vent holes 324 connect the second accommodating cavity 322 and the refrigeration chamber 13. The specific position and structure of the third vent holes 324 on the third clamping surface 323 are similar to those of the first vent holes 315, and are not described again here.

[0100] In this way, along the arrangement direction of the first mounting member 31, the second mounting member 32 and the first blister air duct plate 22, the first air duct 211, the first accommodating chamber 311, the second accommodating chamber 322 and the refrigeration chamber 13 can be directly connected, so that in the above-mentioned second air flow circulation, the flow direction of the airflow can be changed to: refrigeration chamber 13—return air outlet 212—first air duct 211—first air vent 315—first catalyst block—second air vent 221—second catalyst block—third air vent 324—refrigeration chamber 13.

[0101] In this way, the airflow in the refrigerator 1 can pass through two layers of filtering in the second airflow circulation, thereby effectively improving the sterilization effect of the airflow, which is beneficial to prolonging the preservation time of the food placed in the refrigeration chamber 13.
