[0002] A refrigerator is a refrigeration device that maintains a constant low temperature and is widely used in the fields of life and industry. A refrigerator can extend the preservation period of food. However, if food is stored for too long, it will also produce bacteria and odors due to spoilage, which affects the hygiene of other foods stored in the refrigerator.

[0003] In the related art, a duct is formed by arranging a liner of a refrigerator and a plastic suction duct board at intervals, and a catalyst block is installed at the air return opening of the plastic suction duct board. When the air flow in the liner passes through the air return opening for circulating flow, the bacteria and odors generated by spoiled food in the liner can be removed through the catalytic action of the catalyst block, so as to maintain the hygiene of the food in the liner.

[0004] However, when a user replaces the catalyst block, it is necessary to disassemble part of the plastic suction duct board, and the connection stability of the catalyst block on the plastic suction duct board is poor, which is not convenient for the user to perform daily maintenance on the refrigerator.

[0050] A refrigerator is a refrigeration device that maintains a constant low temperature and is widely used in the fields of life and industry. A refrigerator can extend the storage period of food. However, if the food is stored for too long, it will also produce bacteria and odors due to spoilage, which affects the hygiene of other foods stored in the refrigerator.

[0051] In the related art, a wind duct is formed by arranging a liner of a refrigerator and a plastic suction duct board at intervals, and a catalyst block is installed at the air return opening of the plastic suction duct board. When the air flow in the liner passes through the air return opening for circular flow, the bacteria and odors generated by the spoiled food in the liner can be removed through the catalytic action of the catalyst block, so as to maintain the hygiene of the food in the liner.

[0052] However, when the user replaces the catalyst block, it is necessary to disassemble part of the plastic suction duct board, and the connection stability of the catalyst block on the plastic suction duct board is poor, which is not convenient for the user to perform daily maintenance on the refrigerator.

[0053] To solve the above technical problems, the present application provides a refrigerator that can conveniently replace the catalyst block in the refrigerator, which is convenient for the user to perform daily maintenance on the refrigerator. The structure of the refrigerator will be described in detail below with reference to the accompanying drawings of the specification.

[0054] Figure 1 FIG. 1 shows one of the overall structural schematic diagrams of the refrigerator provided by the embodiments of the present application. Referring to Figure 1 , in some embodiments of the present application, the refrigerator 1 may include a box body 10, and the box body 10 may include an outer shell 11 and a liner 12 disposed inside the outer shell 11. A refrigeration chamber 121 is formed inside the liner 12.

[0055] It should be noted that the refrigeration chamber 121 may 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 food in a refrigerated state; the temperature of the freezing chamber is generally between -14°C and -26°C, which can keep food in a frozen state; the adjustable temperature range of the variable temperature chamber is generally between 5°C and -7°C, or can be directly adjusted to -18°C for use as a freezing chamber.

[0056] Continuing to refer to Figure 1 , in some embodiments of the present application, the box body 10 is also provided with an opening 122 communicating with the refrigeration chamber 121, and a plurality of storage drawers arranged along the height direction of the box body 10 are provided in the refrigeration chamber 121.

[0057] Exemplarily, there are four storage drawers, which are the first drawer 20, the second drawer, the third drawer and the fourth drawer in sequence from bottom to top. In this way, users can place different categories of food in different storage drawers through the above-mentioned opening 122 according to their own usage needs, or take out the food from the storage drawers through the opening 122.

[0058] Figure 2 Fig. 2 shows the second schematic diagram of the overall structure of the refrigerator provided by the embodiment of the present application. Figure 3 It shows Figure 2 the schematic cross-sectional structure at position A-A. With reference to Figure 2 and Figure 3 , in some embodiments of the present application, the refrigerator 1 may further include a plastic suction air duct plate 30. The plastic suction air duct plate 30 is spaced from the inner wall surface of the box liner 12, so as to form a first air flow channel 31. One end of the first air flow channel 31 facing the first drawer 20 downward is an air return port 32.

[0059] Figure 4 It shows Figure 3 the enlarged schematic structure at position B. With reference to Figure 3 and Figure 4 , in some embodiments of the present application, the first drawer 20 is arranged at the bottom of the refrigeration chamber 121, and the first drawer 20 is spaced from the inner wall surface of the box liner 12 to form a second air flow channel 21. The second air flow channel 21 is connected to the first air flow channel 31 through the air return port 32.

[0060] Continue to refer to Figure 4 , in some embodiments of the present application, the refrigerator 1 may further include a connecting piece 40. The connecting piece 40 is arranged in the second air flow channel 21, and the connecting piece 40 is connected to the first drawer 20, so as to form an installation cavity 41 for installing the catalyst block 2.

[0061] There can be various specific connection positions of the above-mentioned connecting piece 40 on the first drawer 20. Exemplarily, the connecting piece 40 can be arranged on the wall surface of the first drawer 20 facing the plastic suction air duct plate 30; Exemplarily, the connecting piece 40 can also be arranged on the wall surface of the first drawer 20 facing the bottom wall surface 123 of the box liner 12. Both connection positions can ensure that the catalyst block 2 installed in the connecting piece 40 is located in the second air flow channel 21.

[0062] Continue to refer to Figure 1 , in some embodiments of the present application, the box liner 12 may further include an air outlet 33. The air outlet 33 is arranged above the refrigeration chamber 121, and the air outlet 33 communicates the first air flow channel 31 and the refrigeration chamber 121.

[0063] According to the above structural arrangement, the second air flow channel 21 is located within the refrigeration chamber 121. The air flow within the refrigeration chamber 121 can first enter the second air flow channel 21 and, when flowing through the second air flow channel 21, undergo a catalytic reaction with the catalyst block 2 within the installation cavity 41 to remove bacteria and odors in the air flow. The treated clean air flow then enters the first air flow channel 31 through the air return opening 32 and flows upward along the first air flow channel 31 until it re-enters the refrigeration chamber 121 through the air outlet 33, completing the circulating flow of the air flow within the inner container 12.

[0064] It can be understood that in the present application, the first drawer 20 is spaced apart from the inner container 12 to form the second air flow channel 21. The connecting member 40 and the catalyst block 2 are disposed within the second air flow channel 21 and are connected to the first drawer 20. In this way, on the basis of ensuring the air cleaning effect, it is convenient for the user to replace the catalyst block 2. When replacing, the user only needs to pull out the first drawer 20 from the inner container 12 to replace the catalyst block 2, without the need to disassemble the plastic suction air duct plate 30, making the replacement process of the catalyst block 2 quick and efficient and facilitating the user's daily maintenance of the refrigerator 1.

[0065] In addition, generally, the structural strength of the first drawer 20 is higher than that of the plastic suction air duct plate 30 (the structural strength of the plastic suction molding is relatively low), which is beneficial to the stable connection between the connecting member 40 and the first drawer 20, thereby making the position of the catalyst block 2 within the second air flow channel 21 more stable.

[0066] It should be noted that when the first drawer 20 is disposed at the bottom of the refrigeration chamber 121, the second air flow channel 21 can be formed. When the catalyst block 2 is disposed within the second air flow channel 21 and near the air return opening 32, it is beneficial for all the air flow circulating within the inner container 12 to pass through the catalyst block 2 for filtration, thereby enhancing the air cleaning effect.

[0067] In some other possible structural designs, the first drawer 20 may not be disposed at the bottom of the refrigeration chamber 121. For example, the first drawer 20 is disposed in the middle of the refrigeration chamber 121, that is, the catalyst block 2 is disposed within the refrigeration chamber 121 but not within the second air flow channel 21. In this way, it is also convenient for the user to replace the catalyst block 2, and at this time, the catalyst block 2 can filter and sterilize the air flow flowing near it.

[0068] Figure 5 Fig. shows one of the structural schematic diagrams of the connecting member provided by the embodiment of the present application. In some embodiments of the present application, the connecting member 40 may include an installation portion 42. One end of the installation portion 42 is connected to the outer wall surface of the first drawer 20 and encloses the installation cavity 41, and the other end of the installation portion 42 is provided with an installation opening communicating with the installation cavity 41.

[0069] Continue to refer to Figure 5In some embodiments of the present application, the connector 40 may further include a stopper 43, which is connected to an end of the mounting portion 42 away from the first drawer 20. When the catalyst block 2 is placed in the mounting cavity 41, one side of the catalyst block 2 abuts against the outer wall surface of the first drawer 20 along the first direction F1, and the other side of the catalyst block 2 abuts against the stopper 43 along the first direction F1, and the first direction F1 is parallel to the arrangement direction of the first drawer 20 and the connector 40.

[0070] In the above-mentioned connecting member 40, the structure of the mounting portion 42 is basically the same, and a plurality of connecting plates can be provided according to the specific shape of the catalyst block 2. The plurality of connecting plates can be interconnected or separated from each other, as long as the plurality of connecting plates and the outer wall surface of the first drawer 20 are combined to form a mounting cavity 41 of a similar size to the catalyst block 2. The specific structure of the limiting portion 43 can be various, which are described below.

[0071] Continue reading Figure 5 In some structural designs, the limiting portion 43 includes a first limiting portion 431 and a second limiting portion 432 , the first limiting portion 431 abuts against the catalyst block 2 along the first direction F1 , and the second limiting portion 432 is arranged opposite to the first limiting portion 431 and extends toward each other.

[0072] Exemplarily, the first limit portion 431 and the second limit portion 432 can be relatively arranged along the first direction F1, and extend along the first direction F1 to form a hook; exemplary, the first limit portion 431 and the second limit portion 432 can also be relatively arranged along the third direction F3, and extend along the third direction F3 to form a hook.

[0073] It should be noted that the hook has a certain elasticity. When the catalyst block 2 is squeezed toward the inside of the hook through the installation opening along the first direction F1, the hook pops open to both sides, allowing the catalyst block 2 to enter the installation cavity 41. After entering, the hook returns to its original position, so that the side wall of the catalyst block 2 abuts against the hook, forming a limit for the catalyst block 2, thereby preventing the catalyst block 2 from escaping from the installation cavity 41.

[0074] Figure 6 The second structural schematic diagram of the connecting member provided in the embodiment of the present application is shown. In another structural design, the first limiting portion 431 and the second limiting portion 432 can also be set in the form of a baffle, and the position of the baffle is set at a lower or upper position of the mounting portion 42.

[0075] In this way, when replacing the catalyst block 2, one end of the catalyst block 2 can be first inserted into the baffle, and then the other end of the catalyst block 2 can be pushed into the installation cavity 41. The replacement process is convenient, and the position of the catalyst block 2 after replacement is stable and not easy to fall out of the installation cavity 41.

[0076] Figure 7FIG. 3 shows a schematic structural diagram of a connector provided by an embodiment of the present application. Referring in combination to Figure 4 and Figure 7 , in yet another structural design, the limiting portion 43 may also be provided as a cover body, and the cover body and the mounting portion 42 may be rotatably connected along the first direction F1 or the third direction F3, so as to open or close the mounting opening.

[0077] It should be noted that a communication hole 430 communicating the installation cavity 41 and the second air flow channel 21 is provided on the cover body, so as to ensure that when the air flow passes through the second air flow channel 21, it can enter the installation cavity 41, and then flow into the second air flow channel 21 after being catalytically treated by the catalyst block 2.

[0078] Figure 8 FIG. 3 shows a schematic overall structural diagram of a refrigerator provided by an embodiment of the present application. Figure 9 FIG. shows Figure 8 an enlarged structural diagram at position C. Referring in combination to Figure 4 , Figure 8 and Figure 9 , in some embodiments of the present application, the inner liner 12 includes a bottom wall surface 123 and a sliding support portion 124. The sliding support portion 124 is provided between the bottom wall surface 123 and the first drawer 20, so as to space apart the bottom wall surface 123 and the first drawer 20 and form a first return channel 211, and the first return channel 211 is at least part of the second air flow channel 21.

[0079] It should be noted that there may be multiple such sliding support portions 124, for example, two. The two sliding support portions 124 may be provided on opposite sides of the bottom wall surface 123 along the first direction F1, or may be provided at the middle position of the bottom wall surface 123, as long as the bottom wall surface 123 and the first drawer 20 can be separated. In addition, the sliding support portion 124 may be directly formed by stamping the bottom wall surface 123 of the inner liner 12, or may be welded to the bottom wall surface 123 of the inner liner 12 as an independent component.

[0080] It can be understood that, on the one hand, the sliding support portion 124 can separate the bottom wall surface 123 and the first drawer 20, facilitating the air flow in the refrigeration chamber 121 to bypass the first drawer 20 through the first return channel 211 and enter the first air flow channel 31; on the other hand, the sliding support portion 124 can provide guidance and support for the sliding of the first drawer 20 along the first direction F1, thus facilitating the user to pull the first drawer 20 for sliding.

[0081] Figure 10 FIG. shows Figure 8 an enlarged structural diagram at position D. Referring in combination to Figure 4 , Figure 8 and Figure 10, in some embodiments of the present application, an abutting portion 22 is provided on one side of the first drawer 20 away from the bottom wall surface 123. The specific structural form of the abutting portion 22 can be various. For example, it can be set as a trapezoidal bump, a rectangular bump or a triangular bump.

[0082] Continue to refer to Figure 4 , Figure 8 and Figure 10 , the box liner 12 may further include a first side wall surface 125, and the first side wall surface 125 is connected to the bottom wall surface 123.

[0083] Continue to refer to Figure 4 , Figure 8 and Figure 10 , the box liner 12 may further include a second side wall surface 126. The second side wall surface 126 is connected to both the bottom wall surface 123 and the first side wall surface 125, and a first stopping portion 1261 is provided at one end of the second side wall surface 126 facing the thermoformed air duct plate 30.

[0084] It should be noted that the specific structure of the first stopping portion 1261 needs to be set according to the specific structure of the above-mentioned abutting portion 22. For example, when the structure of the abutting portion 22 is set as a trapezoidal bump, the structure of the first stopping portion 1261 is correspondingly set as a trapezoidal groove, so as to ensure that the abutting portion 22 and the first stopping portion 1261 can be stably abutted, so that the spatial structure of the second return channel 212 is kept stable.

[0085] It can be understood that, in the process of the user pushing the first drawer 20 into the refrigeration chamber 121 along the first direction F1, when the first drawer 20 advances to a certain position, the abutting portion 22 provided above the first drawer 20 can abut against the first stopping portion 1261 of the box liner 12 along the first direction F1, preventing the first drawer 20 from continuing to advance and fitting with the first side wall surface 125 of the box liner 12. In this way, the first drawer 20 can form a second return channel 212 with the first side wall surface 125, so that the air flow bypassing the first drawer 20 through the first return channel 211 can continue to flow along the second return channel 212 towards the first air channel 31, thereby ensuring the smoothness of the air flow circulation in the box liner 12 and being beneficial to the continuous cleaning of the air flow by the catalyst block 2.

[0086] Figure 11 Figure 4 shows the overall structural schematic diagram of the refrigerator provided by the embodiment of the present application. Figure 12 Shows Figure 11 The enlarged structural schematic diagram at position E. Referring in combination to Figure 4 , Figure 11 and Figure 12, in some embodiments of the present application, the second side wall surface 126 is further provided with a second stopping portion 1262. The second stopping portion 1262 is provided at one end of the second side wall surface 126 away from the plastic suction duct plate 30, and the second stopping portion 1262 is disposed opposite to the first stopping portion 1261 along the first direction F1.

[0087] It should be noted that the specific structure of the second stopping portion 1262 is the same as that of the first stopping portion 1261, and it needs to be set according to the structure of the abutting portion 22. When the structure of the abutting portion 22 is set as a trapezoidal protrusion, the structure of the second stopping portion 1262 is also set as a corresponding trapezoidal groove.

[0088] In this way, during the process of the user pulling out the first drawer 20, when the first drawer 20 is pulled out a certain length, the second stopping portion 1262 can abut against the abutting portion 22, avoiding the first drawer 20 completely coming out of the refrigeration chamber 121 due to excessive force, and there is no need to assemble the first drawer 20 and the box liner 12 again, thus facilitating the normal use of the user. And when it is necessary to completely take out the first drawer 20 and replace the catalyst block 2, the first drawer 20 can be tilted slightly during the process of pulling the first drawer 20, so that the abutting portion 22 avoids the blocking of the second stopping portion 1262, and thus the first drawer 20 can be conveniently taken out to complete the replacement of the catalyst block 2.

[0089] Figure 13 The structural schematic diagram of the first drawer provided by the embodiment of the present application is shown. With reference to Figure 4 , Figure 12 and Figure 13 , in some embodiments of the present application, a plugging portion 23 is provided on one side of the first drawer 20 facing the plastic suction duct plate 30. The plugging portion 23 can extend along the first direction F1 to form a plate-like structure.

[0090] Continuing to refer to Figure 4 , Figure 12 and Figure 13 , in some embodiments of the present application, the second side wall surface 126 of the box liner 12 is further provided with a connecting groove 1263. The specific structure of the connecting groove 1263 needs to be set according to the structure of the plugging portion 23. Along the first direction F1, the connecting groove 1263 is provided on one side of the first stopping portion 1261 away from the second stopping portion 1262. Wherein, when the abutting portion 22 abuts against the first stopping portion 1261, the plugging portion 23 is connected to the connecting groove 1263.

[0091] Understandably, on the one hand, during the process of the user pushing the first drawer 20 into the refrigeration chamber 121, when the first stop portion 1261 abuts against the abutting portion 22, the connection between the plugging portion 23 and the connection groove 1263 can improve the installation stability of the first drawer 20; on the other hand, since the first drawer 20 needs to be spaced apart from the second side wall surface 126 of the inner container 12 to form a second return channel 212, there is also a certain gap between the first drawer 20 and the plastic suction duct board 30. When the air flow flows through the second return channel 212 to the first air flow channel 31, a small part of the air flow flows through the above-mentioned gap into the refrigeration chamber 121. When the plugging portion 23 is connected to the connection groove 1263, a blocking and sealing effect can be formed, so that the air flow in the second return channel 212 can all enter the first air flow channel 31, thereby ensuring the stable and orderly circulation of the air flow in the inner container 12.

[0092] Figure 14 FIG. 5 shows a schematic diagram of the overall structure of the refrigerator provided by the embodiment of the present application. Referring in combination to Figure 4 and Figure 14 , in some embodiments of the present application, the heat exchanger 3 is arranged in the first air flow channel 31. Since the catalyst block 2 is arranged on the first drawer 20 through the connecting member 40 and is located in the second return channel 212 formed by the first drawer 20 and the second side wall surface 126, and the second return channel 212 is located below the first air flow channel 31, therefore, the heat exchanger 3 is located above the catalyst block 2.

[0093] Understandably, due to the circulating flow of the air flow in the refrigerator 1, the catalyst block 2 is long-term exposed to humid air, resulting in the phenomenon that the catalyst block 2 is prone to crushing and falling off. In the traditional structural design, the catalyst block 2 is usually arranged at the upper position of the heat exchanger 3. The debris after the catalyst block 2 falls off will cause corrosion of the heat exchanger 3 when it falls on the heat exchanger 3. In the structural solution of the present application, the heat exchanger 3 is arranged above the catalyst block 2. In this way, even if the debris of the catalyst block 2 falls off, it will not fall on the heat exchanger 3, thereby effectively avoiding the phenomenon of corrosion of the heat exchanger 3.
