Detailed Description

[0031] The following will provide a detailed description of the specific embodiments of the present disclosure in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0032] As used herein, the term "including" and its variants are open-ended, that is, "including but not limited to". The term "based on" means "at least partially based on". The term "an embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment". The relevant definitions of other terms will be given in the following description.

[0033] It should be noted that the concepts such as "first" and "second" mentioned in this disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or mutual dependency relationship of the functions performed by these devices, modules or units.

[0034] It should be noted that the modifications of "one" and "multiple" mentioned in this disclosure are illustrative rather than restrictive. Those skilled in the art should understand that unless otherwise clearly specified in the context, it should be understood as "one or more".

[0035] In this disclosure, it should be understood that the orientation words such as "up, down, left, right" are usually defined according to the drawing direction of the drawings, and are only for the convenience of describing this disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, as well as a specific orientation structure and operation. Therefore, it cannot be understood as a limitation to this disclosure.

[0036] In the description of this disclosure, it should also be noted that unless otherwise clearly specified and limited, the terms "arrange", "connect", "couple", "install" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in this disclosure can be understood according to specific circumstances.

[0037] As mentioned above, users' requirements for the quality of travel are constantly increasing, and in-vehicle refrigerators have gradually become an important part of vehicles. However, traditional in-vehicle refrigerators usually adopt a scheme of indirect cooling of the inner liner. The cold generated by the evaporator is not directly transferred to the items placed in the in-vehicle refrigerator, but first transferred to the inner liner of the in-vehicle refrigerator, and then transferred to the items through the air. The cold transfer efficiency of the scheme of indirectly cooling the items through the inner liner is relatively low, and it takes a long time to cool the items, resulting in users not being able to obtain a good user experience.

[0038] In view of this, as Figures 1 to 5 shown, according to the first aspect of this disclosure, a refrigerator 100 is provided, which includes an article placement member 20 and a convection device 30. The article placement member 20 is provided with a receiving cavity 21 for receiving items. An air inlet 221 communicating with the receiving cavity 21 is formed on the side wall of the article placement member 20. The air outlet 31 of the convection device 30 is arranged facing the air inlet 221. The air flow blown out from the air outlet 31 of the convection device 30 enters the receiving cavity 21 through the air inlet 221 and flows towards the first side wall 251 of the receiving cavity 21. The air outlet direction A of the air outlet 31 of the convection device 30 is inclined with respect to the first side wall 251.

[0039] The refrigerator 100 provided by the present disclosure can be used in any suitable scenario. For example, the above-mentioned refrigerator 100 can be used as an in-vehicle refrigerator for a vehicle, so as to meet the user's requirements for travel quality. The above-mentioned refrigerator 100 can also be used as a household refrigerator (such as a kitchen refrigerator, a baby care refrigerator, a wine cabinet refrigerator, etc.), a medical refrigerator, a commercial freezer, a laboratory refrigerator, etc. The present disclosure does not limit this.

[0040] In addition, the present disclosure does not limit the specific working mode of the above-mentioned refrigerator 100. The above-mentioned refrigerator 100 can be a refrigerating refrigerator for refrigeration, which can quickly cool items. Or, the above-mentioned refrigerator 100 can also be a heating refrigerator for heating, so as to meet the preservation requirements of specific items. Or, the above-mentioned refrigerator 100 can also have both refrigeration and heating modes at the same time, and can be adjusted according to user needs, so as to meet different usage scenarios of users.

[0041] In the above-mentioned refrigerator 100, the accommodating cavity 21 of the placing member 20 can be used to accommodate items such as food, beverages, and medicines.

[0042] Through the above technical solution, since a convection device 30 is provided in the refrigerator 100, an air inlet 221 communicating with the accommodating cavity 21 is provided on the placing member 20 for accommodating items, and the air outlet 31 of the convection device 30 is arranged facing the air inlet 221. In this way, through the cooperation of the convection device 30 and the air inlet 221 provided on the placing member 20, air can enter the accommodating cavity 21. In this way, through the convection device 30, it is beneficial to make the cold or heat generated by the refrigeration or heating structure enter the accommodating cavity 21 along with the gas through the air inlet 221 on the placing member 20 under the action of the convection device 30, and contact the items placed in the accommodating cavity 21 to achieve heat exchange. After heat exchange, the heat or cold follows the gas (for example, through the placing member air outlet 27 provided on the placing member 20) and flows back outside the accommodating cavity 21 and circulates continuously. This circulation can improve the heat exchange efficiency and can quickly cool or heat the items.

[0043] Moreover, since the air outlet direction of the air outlet 31 of the convection device 30 is inclined with respect to the first side wall 251 of the accommodating cavity 21, in this way, it is beneficial to make the airflow blown out by the convection device 30 collide with the first side wall 251, and the first side wall 251 can change the flow direction of the airflow, which is beneficial to form a circulation, that is, it is beneficial to realize the circulating flow of the heat exchange airflow in the accommodating cavity 21, and the airflow reaches different positions in the accommodating cavity 21, so that local overheating or overcooling phenomena are not likely to occur at different positions in the accommodating cavity 21, and it has a good heat exchange effect and heat exchange efficiency, and the fresh-keeping effect of the refrigerator 100 is good, which can effectively avoid the occurrence of situations such as local temperature differences in the refrigerator 100 leading to easy growth of bacteria and easy damage of items.

[0044] For example, asFigures 2 to 5 As shown in the figure, the accommodation cavity 21 is provided with a first side wall 251, a second side wall 252, a third side wall 255 and a fourth side wall 256. The air flow blown out by the convection device 30 can first flow into the accommodation cavity 21 through the air inlet 221, collide with the first side wall 251, and flow towards the fourth side wall 256 under the blocking action of the first side wall 251, and then flow towards the third side wall 255 and the second side wall 252 in sequence, and finally flow back to the first side wall 251 again. The air flow can form a circulating flow, flow through different positions in the accommodation cavity 21, and exchange heat with the articles at different positions.

[0045] In addition, since the air outlet 31 of the convection device 30 is arranged towards the air inlet 221, the distance between the convection device with the air outlet 31 arranged towards the air inlet 221 and the air inlet 221 is relatively short, or the air outlet 31 of the convection device 30 is attached to the side wall (such as the second side wall 252 mentioned below) where the air inlet 221 is located on the object placement member 20. At this time, the second side wall 252 can be inclined relative to the first side wall 251 so that the air outlet direction A of the air outlet 31 of the convection device 30 can be inclined relative to the first side wall 251. When the air flow of the convection device 30 flows out from the air outlet 31, the air flow can directly flow into the accommodation cavity 21 through the air inlet part 22 and exchange heat with the articles in the accommodation cavity 21. Other components in the refrigerator 100 will not block the air flow, effectively avoiding the situation that other components in the refrigerator 100 affect the normal flow of the air flow and further affect the heat exchange efficiency of the articles; moreover, the air flow flowing out from the air outlet 31 is not likely to flow to other positions in the refrigerator 100, effectively avoiding the situation that the random flow of the air flow in the refrigerator 100 will also affect the heat exchange efficiency of the articles. In addition, the convection device 30 being attached to the air inlet part 22 is also beneficial to improving the structural compactness in the refrigerator 100.

[0046] In order to make the direction of the air flow flowing into the accommodation cavity 21 through the air inlet 221 inclined to the first side wall 251, as an implementation manner of the present disclosure, as Figures 2 to 5 shown, the above-mentioned air inlet 221 is located on the second side wall 252 of the accommodation cavity 21. The second side wall 252 is arranged at an angle with the first side wall 251. The end face of the air outlet 31 close to the second side wall 252 is inclined relative to the second side wall 252 so that the air outlet direction of the air outlet 31 can be inclined relative to the first side wall 251. That is, along the extending direction of the second side wall 252, the side of the air outlet 31 far from the first side wall 251 is closer to the second side wall 252 than the side close to the first side wall 251.

[0047] Since the end face of the air outlet 31 of the convection device 30 close to the second side wall 252 is inclined relative to the second side wall 252, by reasonably designing the included angle between the end face of the air outlet 31 of the convection device 30 close to the second side wall 252 and the second side wall 252, and the included angle between the first side wall 251 and the second side wall 252, the air flow blown out from the air outlet 31 of the convection device 30 can be blown obliquely onto the second side wall 252 of the accommodation cavity 21 and flow into the accommodation cavity 21 through the air inlet 221 provided on the second side wall 252, forming the above-mentioned circulating flow.

[0048] When the thickness of the second side wall 252 is relatively small, the air inlet 221 hardly changes the direction of the air flow, and the air flow can directly pass through the air inlet 221 and blow onto the first side wall 251 having an included angle with the second side wall 252, so that the circulating flow of the air flow in the accommodation cavity 21 can be realized.

[0049] As other embodiments of the present disclosure, the second side wall 252 may have a certain thickness. At this time, the axis of the air inlet 221 may be inclined relative to the first side wall 251. In this way, the air inlet 221 does not change the air outlet direction of the air outlet 31 of the convection device 30 either, and the direction of the air flow flowing into the accommodation cavity 21 through the air inlet 221 can also be inclined to the first side wall 251, enabling the air flow to blow onto the second side wall 252 at a preset angle, effectively avoiding the situation that due to the relatively large thickness of the second side wall 252 and the relatively long channel of the air inlet 221, the flow direction of the air flow changes, affecting the circulation of the air flow in the accommodation cavity 21.

[0050] In the present disclosure, any appropriate included angle may be provided between the first side wall 251 and the second side wall 252. Optionally, as Figures 2 to 5 shown, the above-mentioned second side wall 252 and the first side wall 251 are arranged perpendicular to each other. The mutually perpendicular first side wall 251 and second side wall 252 can simplify the overall design difficulty of the refrigerator 100 on the one hand. The first side wall 251 and the second side wall 252 are not likely to interfere with the arrangement of other components in the refrigerator 100, facilitating the arrangement of other components in the refrigerator 100. On the other hand, the mutually perpendicular first side wall 251 and second side wall 252 can also avoid the overall shape of the refrigerator 100 changing due to overly irregular shapes, which is not conducive to the situation where the user arranges it in a usage scenario, such as in a vehicle.

[0051] In addition, the vertically arranged first side wall 251 and second side wall 252 are also beneficial to making the overall structure of the accommodation cavity 21 square. The processing of the square accommodation cavity 21 is relatively simple, effectively avoiding the situation where a special-shaped accommodation cavity 21 needs to be manufactured by multiple processes and the processing is complex.

[0052] Moreover, since the first side wall 251 and the second side wall 252 are perpendicularly arranged, it is convenient to design the inclination angle of the air outlet 31 relative to the second side wall 252 according to the angle of the air outlet direction of the preset air outlet 31 relative to the first side wall 251.

[0053] The present disclosure does not limit the specific structure of the opposed object 20. Optionally, as Figures 2 to 5 shown, the above-mentioned accommodation cavity 21 further includes a third side wall 255 and a fourth side wall 256. The third side wall 255 is arranged opposite to the first side wall 251, the fourth side wall 256 is arranged opposite to the second side wall 252, the first side wall 251 is connected between the second side wall 252 and the fourth side wall 256, and the third side wall 255 is connected between the second side wall 252 and the fourth side wall 256. Among them, after the air flow blown out from the air outlet 31 enters the accommodation cavity 21 through the air inlet 221, it can have a circulating air path that sequentially flows through the first side wall 251, the fourth side wall 256, the third side wall 255, the second side wall 252 and returns to the first side wall 251. The first side wall 251, the second side wall 252, the third side wall 255 and the fourth side wall 256 cooperate with each other to jointly enclose an accommodation cavity 21 for accommodating articles.

[0054] In addition, the first side wall 251, the second side wall 252, the third side wall 255 and the fourth side wall 256 cooperate with each other to also be able to form a circulating flow of air in the accommodation cavity 21, thereby exchanging heat with the articles at different positions in the accommodation cavity 21, and being able to improve the uniformity of the temperature at different positions in the accommodation cavity 21 and enhance the heat exchange effect.

[0055] In order to further improve the circulating effect of the air flow in the accommodation cavity 21, optionally, as Figure 4 shown, one or more of the above-mentioned first side wall 251, second side wall 252, third side wall 255 and fourth side wall 256 are not provided with through holes communicating with the accommodation cavity 21.

[0056] Since at least one or more side walls of the accommodation cavity 21 (i.e., the first side wall 251, the second side wall 252, the third side wall 255 and the fourth side wall 256 mentioned above) are not provided with through holes communicating with the accommodation cavity 21, in this way, when the air flow collides with the first side wall 251, the second side wall 252, the third side wall 255 and the fourth side wall 256, the air flow will not directly flow out of the outside of the accommodation cavity 21 through the first side wall 251, the second side wall 252, the third side wall 255 and the fourth side wall 256. This is beneficial to increasing the amount of circulating gas in the accommodation cavity 21, thereby being able to further improve the circulating effect of the air flow in the accommodation cavity 21 and enabling the refrigerator 100 to have better heat exchange capacity and heat exchange efficiency.

[0057] In order to realize the internal and external circulation of the air flow in the accommodation cavity 21, optionally, as Figures 2 to 5As shown, an object placing outlet 27 communicating with the accommodation cavity 21 is provided on the top side of the above-mentioned object placing member 20. In this way, after the air flow exchanges heat with the articles sufficiently, the air flow can flow out of the accommodation cavity 21 through the object placing outlet 27 provided on the top side of the object placing member 20, and after exchanging heat with the refrigerating or heating structure in the refrigerator 100, under the action of the convection device 30, it flows back into the accommodation cavity 21, so that the internal and external circulation of the air flow in the accommodation cavity 21 can be realized.

[0058] Optionally, the object placing outlet 27 can also be provided on the bottom wall of the accommodation cavity 21.

[0059] As other embodiments of the present disclosure, such as Figures 1 to 3 and Figure 5 As shown, ventilation holes 23 communicating with the accommodation cavity 21 can also be provided on the first side wall 251 and the third side wall 255. In this way, after the air flow exchanges heat with the articles sufficiently, the air flow can also flow out of the accommodation cavity 21 through the ventilation holes 23 provided on the first side wall 251 and the third side wall 255, and after exchanging heat with the refrigerating or heating structure in the refrigerator 100, under the action of the convection device 30, it flows back into the accommodation cavity 21, so that the internal and external circulation of the air flow in the accommodation cavity 21 can be realized.

[0060] In addition, the relatively arranged ventilation holes 23 can all allow the gas to flow through, which can further make the gas flow to different parts in the accommodation cavity 21, so that different positions in the accommodation cavity 21 have the same heat exchange capacity, and the temperature uniformity of the accommodation cavity 21 is relatively high, which is beneficial to further improving the fresh-keeping effect of the refrigerator 100.

[0061] Optionally, as Figures 1 to 3 shown, the ventilation holes 23 on the first side wall 251 and the third side wall 255 are symmetrically arranged about the midpoint of the connection line between the first side wall 251 and the third side wall 255. The symmetrically arranged ventilation holes 23 can further make the gas flow to different parts in the accommodation cavity 21, so as to further improve the temperature uniformity of the accommodation cavity 21.

[0062] Here, it should be noted that the object placing member 20 provided in the present disclosure can have any appropriate exhaust mode. For example, the object placing member 20 can exhaust through the above-mentioned object placing outlet 27 or ventilation holes 23, so as to realize the internal and external circulation of the air flow in the accommodation cavity 21. Or, the object placing member 20 can also be provided with the above-mentioned object placing outlet 27 and ventilation holes 23 at the same time, and the gas can be discharged through the object placing outlet 27 and the ventilation holes at the same time. In this way, the circulation of the air flow inside and outside the accommodation cavity 21 can also be realized.

[0063] For the embodiment in which ventilation holes 23 communicating with the accommodation cavity 21 are provided on both the first side wall 251 and the third side wall 255, the present disclosure does not limit the specific type of the ventilation holes 23 either. For example, the ventilation holes 23 can also be configured as ventilation holes 23 with a smaller diameter, as long as the ventilation holes 23 can meet the gas flow requirements. As an embodiment of the present disclosure, as Figures 1 to 3 and Figure 5 shown, the above-mentioned ventilation holes 23 are ventilation holes 23 with a smaller diameter.

[0064] In addition, multiple ventilation holes 23 with a smaller diameter can also disperse the stress on the positions where the ventilation holes 23 are provided on the first side wall 251 and the third side wall 255, reduce stress concentration, have less influence on the strength of the first side wall 251 and the third side wall 255 themselves, and are beneficial to improving the durability and service life of the first side wall 251 and the third side wall 255.

[0065] It should be noted that for the embodiment in which the ventilation holes 23 are configured as multiple ventilation holes 23, the present disclosure does not limit the arrangement manner of the multiple ventilation holes 23 on the first side wall 251 and the third side wall 255 either. The arrangement areas of the multiple ventilation holes 23 on the first side wall 251 and the third side wall 255 can be in any suitable shape. As an embodiment of the present disclosure, as Figures 1 to 3 and Figure 5 shown, the multiple ventilation holes 23 at least form a rhombus hole area on the first side wall 251 and the third side wall 255, that is, the arrangement areas of the above-mentioned multiple ventilation holes 23 on the first side wall 251 and the third side wall 255 at least include a rhombus hole area. The multiple ventilation holes 23 arranged in a rhombus have better aesthetics and can meet the aesthetic requirements of users.

[0066] The present disclosure does not limit the specific arrangement manner of the air inlet 221 on the object placement member 20 either. As an embodiment of the present disclosure, as Figures 1 to 5 shown, an air inlet part 22 is provided on the side wall of the above-mentioned object placement member 20, at least one air inlet 221 is provided on the air inlet part 22, and the shape of the air outlet 31 of the convection device 30 is adapted to the shape of the air inlet part 22. In this way, on the one hand, by adapting the shape of the air inlet part 22 to the shape of the air outlet 31, it is convenient to design the shape of the air inlet part 22 according to the shape of the air outlet 31 of the convection device 30, which is convenient for the design of the air inlet part 22; on the other hand, the air inlet part 22 adapted to the shape of the air outlet 31 can also guide the airflow flowing into or out of the accommodation cavity 21 through the air outlet 31, facilitating the passage of the airflow.

[0067] Optionally, as Figures 2 to 4As shown, the size of the air outlet 31 of the above-mentioned convection device 30 is adapted to the size of the air inlet portion 22. The air inlet portion 22 with adapted size can fully introduce the air flow of the air outlet 31 into the accommodation cavity 21, or suck the air flow out of the accommodation cavity 21, thereby ensuring the heat exchange efficiency of the article.

[0068] In addition, the size of the air inlet portion 22 adapted to the size of the air outlet 31 is not too large, which is convenient for production and manufacturing.

[0069] In the present disclosure, the air inlet portion 22 can have any suitable type. For example, a relatively large-diameter air inlet 221 can be provided on the air inlet portion 22 for gas to flow through, or multiple relatively small-diameter air inlets 221 can be provided on the air inlet portion 22. The present disclosure does not limit this. As an implementation manner of the present disclosure, as Figure 5 shown, the above-mentioned air inlet portion 22 includes a plurality of air inlets 221 communicating with the accommodation cavity 21. The multiple relatively small-diameter air inlets 221 cooperate with each other to also meet the requirement for gas to flow through.

[0070] In addition, the multiple relatively small-diameter air inlets 221 can also disperse the stress received by the air inlet portion 22, reduce stress concentration, have less influence on the strength of the air inlet portion 22 itself, and are beneficial to improving the durability and service life of the air inlet portion 22.

[0071] It should be noted that for the implementation manner in which the air inlet portion 22 includes a plurality of air inlets 221, the present disclosure does not limit the specific arrangement manner of the plurality of air inlets 221 on the air inlet portion 22 either. The arrangement area of the plurality of air inlets 221 on the air inlet portion 22 can be in any suitable shape. As an implementation manner of the present disclosure, as Figure 5 shown, the plurality of air inlets 221 include multiple groups of air inlets 221. The multiple air inlets 221 in each group of air inlets 221 are arranged at intervals along the same circumference, and the larger-diameter one of the circumferences where adjacent two groups of air inlets 221 are located is sleeved outside the other. In other words, the arrangement area of the plurality of air inlets 221 on the air inlet portion 22 is in the shape of a multi-ring disk. The plurality of air inlets 221 in the shape of a multi-ring disk can not only be adapted to the shape and size of the convection device 30, but also take into account higher aesthetics, which is beneficial to improving the aesthetics of the entire air inlet portion 22.

[0072] As other implementation manners of the present disclosure, the arrangement area of the above-mentioned plurality of air inlets 221 on the air inlet portion 22 can also be in the shape of a square, a rhombus or other shapes. The present disclosure does not limit this.

[0073] Here, it should be noted that the present disclosure does not limit the size of the plurality of air inlets 221 either. Optionally, as Figure 5As shown, along the direction from the outer peripheral surface of the circumference to the center of the circle, the diameters of multiple groups of air inlets 221 gradually decrease. The multiple groups of air inlets 221 with gradually decreasing diameters can not only meet the flow of gas but also take into account higher aesthetics.

[0074] The present disclosure does not limit the specific type of the opposing object 20. For the convenience of putting an item into the refrigerator 100 or taking an item out of the refrigerator 100. As an implementation manner of the present disclosure, as Figure 1 shown, an opening 11 is formed in the housing 10 of the refrigerator 100 described above. The opposing object 20 includes at least one drawer 24 movably disposed in the housing 10. The drawer 24 includes a main body 25 and a door body 26 connected to the main body 25. That is, the main body 25 and the door body 26 can jointly define a receiving cavity 21. The door body 26 is used to open or close the opening 11. The receiving cavity 21 has a first side wall 251 and a second side wall 252 opposite to the door body 26. The first side wall 251 is located between the second side wall 252 and the door body 26. An air inlet 221 is provided on the second side wall 252. In this way, by simply pulling out the drawer 24 from the housing 10, the taking and placing of items can be realized. The taking and placing of items in the refrigerator 100 is relatively convenient, which is beneficial to further improving the user experience.

[0075] Moreover, since the drawer 24 includes the main body 25 and the door body 26, and the door body 26 can open or close the opening 11 of the housing 10, in this way, the opening 11 of the refrigerator 100 can be sealed through the drawer 24, and there is no need to separately provide a box door for the refrigerator 100. This is beneficial to simplifying the overall structure of the refrigerator 100, improving the compactness of the refrigerator 100, and facilitating the arrangement of the refrigerator 100 in a vehicle.

[0076] In addition, by providing the air inlet 221 on the second side wall 252 opposite to the door body 26, the loss of cold air or hot air from the side of the door body 26 when the refrigerator 100 is opened can also be reduced. At the same time, by providing the air inlet 221 on the second side wall 252 far from the door body 26 and reasonably designing the position of the refrigeration structure or the heating structure in the refrigerator 100, the gas can start to circulate from the area close to the refrigeration structure or the heating structure (such as the low-temperature area where the evaporator is located), and return after exchanging heat with the item. This is beneficial to realizing the full circulation of the gas in the receiving cavity 21 and the full heat exchange between the gas and the item, thereby being beneficial to improving the heat exchange efficiency of the item.

[0077] Here, it can be understood that for the implementation manner in which the opposing object 20 is configured as the drawer 24, the open side located above the drawer 24 can be configured as the above-mentioned opposing object air outlet 27. In this way, without processing a dedicated opposing object air outlet 27 on the drawer 24, the outflow of the gas in the receiving cavity 21 can be realized, which is beneficial to reducing the production and manufacturing difficulty of the drawer 24.

[0078] To further facilitate the user in retrieving items, optionally, an access opening may also be provided at the top of the outer shell 10 of the refrigerator 100. In this way, the storage and retrieval of items in the refrigerator 100 can also be achieved through the access opening, further facilitating the user in retrieving items.

[0079] As other embodiments of the present disclosure, the placement member 20 may also be an inner liner type placement member fixed within the outer shell 10, and the present disclosure does not limit this.

[0080] Optionally, as Figures 2 to 4 shown, the accommodating cavity 21 further includes a third side wall 255 located between the second side wall 252 and the door body 26. The third side wall 255 is arranged corresponding to the first side wall 251. The lower part of the door body 26 is configured as a fourth side wall 256 opposite to the second side wall 252. The top side of the main body 25 is open to form an air outlet 27 of the placement member communicating with the accommodating cavity 21. The first side wall 251, the second side wall 252, the third side wall 255, and the door body 26 cooperate with each other to jointly enclose the accommodating cavity 21 for accommodating items.

[0081] In addition, through the air outlet 31 of the placement member 20 on the top side of the main body 25, the internal and external circulation of air flow in the accommodating cavity 21 can also be realized.

[0082] To avoid the situation where items fall during the opening or closing of the door, optionally, as Figure 5 shown, the main body 25 includes a blocking portion 253 provided at the upper end of the second side wall 252. The blocking portion 253 is used to block the items in the accommodating cavity 21 from falling out of the accommodating cavity 21. The relatively high blocking portion 253 can play a role in blocking the items, effectively avoiding the situation where when pulling the drawer 24 during the opening or closing of the door, the items placed in the drawer 24 shake due to inertia and are likely to fall out of the drawer 24, or even get stuck between the second side wall 252 of the drawer 24 and the inner wall 12 of the outer shell 10 on the side far away from the opening 11, affecting the normal opening and closing of the refrigerator 100, and improving the user experience.

[0083] In addition, the relatively high blocking portion 253 can also play a role in shielding other structures inside the refrigerator 100, such as the slide rails of the drawer 24 and the convection device 30, which is beneficial to improving the aesthetics of the refrigerator 100.

[0084] To facilitate manufacturing, optionally, the blocking portion 253 and the second side wall 252 are integrally formed. In this way, only one processing is required to manufacture the blocking portion 253 and the second side wall 252, and the production and manufacturing efficiency of the blocking portion 253 and the second side wall 252 is relatively high, which is beneficial to improving the overall production and manufacturing efficiency of the refrigerator 100.

[0085] As other embodiments of the present disclosure, the above-mentioned blocking portion 253 and the second side wall 252 can also be processed separately and then assembled with each other. The present disclosure does not limit this.

[0086] Here, it should be noted that the present disclosure does not limit the specific shape of the above-mentioned blocking portion 253, and the above-mentioned blocking portion 253 can be of any suitable shape. As one embodiment of the present disclosure, as Figure 5 shown, the above-mentioned blocking portion 253 includes an arc-shaped plate 254, and the arc-shaped plate 254 and a part of the second side wall 252 together constitute an air inlet portion 22, and at least one air inlet 221 is provided on the air inlet portion 22. By making the arc-shaped plate 254 provided on the upper part of the second side wall 252 and the second side wall 252 together constitute the air inlet portion 22, the height of the bottom wall of the convection device 30 relative to the inner bottom wall of the outer shell 10 can also be adaptively increased, so that the convection device 30 is not easily interfered with other components in the refrigerator 100 (such as the slide rails of the drawer 24, etc.). In this way, on the premise of adding the convection device 30 in the refrigerator 100 to improve the heat exchange efficiency of items, it is convenient to arrange other components in the refrigerator 100.

[0087] In the refrigerator 100 provided by the present disclosure, the convection device 30 can be installed at any suitable position in the refrigerator 100. The present disclosure does not limit this, as long as the convection device 30 can meet the heat exchange requirements of the items. As one embodiment of the present disclosure, as Figure 1 shown, the refrigerator 100 further includes an outer shell 10, the object placing member 20 is arranged in the outer shell 10, and the above-mentioned convection device 30 can be installed on the inner wall 12 of the outer shell 10. The convection device 30 installed on the inner wall 12 of the outer shell 10 has a good fixing effect in the refrigerator 100 and is not easily shaken.

[0088] Optionally, the above-mentioned refrigerator 100 further includes a mounting bracket, one end of the mounting bracket is installed on the inner wall 12 of the outer shell 10, and the other end of the mounting bracket is connected to the convection device 30. The mounting bracket can realize the fixation of the convection device 30 on the inner wall 12 of the outer shell 10. The installation of the convection device 30 on the inner wall 12 is simple, and the fixing effect is good and it is not easily shaken.

[0089] It should be noted that for the embodiment in which the convection device 30 is installed on the inner wall 12 of the outer shell 10, the convection device 30 can be installed on any inner wall 12 of the outer shell 10. The present disclosure does not limit this. For example, the above-mentioned convection device 30 can be installed on the inner wall 12 on the side of the outer shell 10 far away from the opening 11, or the convection device 30 can also be installed on the top wall, left wall or right wall of the outer shell 10.

[0090] As other embodiments of the present disclosure, the above-mentioned convection device 30 may also be installed on the object placement member 20 (such as the drawer 24). In this way, even when the refrigerator 100 is opened or closed, during the movement of the object placement member 20, the convection device 30 can blow air into the accommodation cavity 21 or suck air out of the accommodation cavity 21, so that the items accommodated in the accommodation cavity 21 can always be at an appropriate temperature, thereby avoiding the influence of the opening and closing of the refrigerator 100, and the loss of cold air or hot air, resulting in the temperature of the items fluctuating back and forth, affecting the normal preservation of the items.

[0091] It should be noted that in the refrigerator 100 provided by the present disclosure, the installation method of the convection device 30 in the refrigerator 100 is not limited to being fixed on a certain component of the refrigerator 100 (such as the inner wall 12 of the outer shell 10 mentioned above, or on the drawer 24). The convection device 30 can also be movably installed in the refrigerator 100. The present disclosure does not limit this. As an embodiment of the present disclosure, the above-mentioned refrigerator 100 further includes a driving mechanism for driving the convection device 30 to rotate to adjust the air outlet or air intake direction of the convection device 30. In this way, when a certain area in the refrigerator 100 needs to be quickly heat-exchanged (i.e., cooled or heated), by means of the driving mechanism, driving the convection device 30 to rotate can change the air outlet or air intake direction of the convection device 30, so that cold air or hot air is blown to different positions in the refrigerator 100, and rapid heat exchange in this area can be achieved, thereby improving the heat exchange efficiency of the items.

[0092] Optionally, the above-mentioned driving mechanism is installed on the inner wall 12 of the outer shell 10, and the convection device 30 is connected to the driving mechanism. In this way, without setting other installation structures, the driving mechanism can not only install the convection device 30 in the outer shell 10, but also drive the convection device 30 to rotate, which is beneficial to simplifying the structure of the refrigerator 100, improving the compactness of the refrigerator 100, and facilitating the layout of the refrigerator 100 in the vehicle.

[0093] It should be noted that the present disclosure does not limit the specific type of the convection device 30 either. The convection device 30 can have any appropriate type as long as it can meet the usage requirements of the refrigerator 100 and is suitable for being arranged in the refrigerator 100. As an embodiment of the present disclosure, as Figures 1 to 4 shown, the above-mentioned convection device 30 includes a fan 32. The fan 32 can blow out gas or suck in gas, so as to realize the internal and external circulation of gas in the accommodation cavity 21, and further realize the heat exchange of the items.

[0094] The present disclosure does not limit the specific type of the above-mentioned fan 32 either. As an embodiment of the present disclosure, the above-mentioned fan 32 can be a centrifugal fan. The centrifugal fan has a higher air pressure and a lower wind noise, and can meet the usage requirements of the refrigerator 100.

[0095] As other embodiments of the present disclosure, the above-mentioned fan 32 may also be a centrifugal fan, an axial flow fan, etc., and the present disclosure does not limit this.

[0096] The convection device 30 provided by the present disclosure is not limited to the above-mentioned fan 32. The convection device 30 may also be any convection device 30 suitable for being arranged in the refrigerator 100. As other embodiments of the present disclosure, the above-mentioned convection device 30 may also include a pump, such as a turbojet pump, etc. The pump can also realize the internal and external circulation of gas in the accommodation cavity 21, thereby realizing the heat exchange of articles.

[0097] Here, it should be noted that in the refrigerator provided by the present disclosure, the refrigerator may have one object placement member or multiple object placement members. For the embodiment in which the refrigerator includes multiple object placement members, optionally, the multiple object placement members are arranged at intervals in the height direction of the refrigerator, and each object placement member is correspondingly provided with a convection device. Since each object placement member is correspondingly provided with a convection device, in this way, the multiple convection devices can respectively realize the internal and external circulation of the gas in the accommodation cavity 21 of the multiple object placement members. Thus, the articles in the multiple object placement members can all have a high heat exchange efficiency, and the user experience is high.

[0098] According to the second aspect of the present disclosure, a vehicle is provided, including the refrigerator 100 as described above.

[0099] This vehicle has all the beneficial effects of the above-mentioned refrigerator 100, which will not be elaborated here.

[0100] It should be noted that the present disclosure does not limit the type of the vehicle either. It can be any vehicle suitable for adopting this refrigerator 100. For example, the vehicle can be a car, a truck, a freight vehicle, etc., and can be a pure electric vehicle, a hybrid vehicle (range-extended vehicle), etc. The present disclosure does not limit this.
