Abstract
Description
Technical Field
[0001] This application relates to the technical field of household appliances, and particularly to an inner liner of a box body and a refrigeration device. Background Art
[0002] As a common household appliance, a refrigerator generally includes an inner liner of a box body and a drawer. To ensure the smooth operation of the drawer, a fixed seat with rollers needs to be installed on the inner liner of the box body to facilitate the smooth pulling out and storage of the drawer.
[0003] During the manufacturing process of a refrigerator, after the fixed seat is assembled with the inner liner of the box body, it is necessary to ensure that there is no leakage problem during the foaming process. However, the existing fixed seat and the inner liner of the box body are connected by a snap connection method, and the sealing performance of this connection method is insufficient, resulting in easy leakage of materials during the foaming process of the refrigerator box body. Therefore, it is usually necessary for workers to stick tape at the assembly position for sealing to avoid material leakage during the foaming process.
[0004] However, this operation of sticking tape not only increases the complexity of the assembly process but also reduces the assembly efficiency. Summary of the Utility Model

[0006] On the one hand, an inner liner of a box body is provided, including:
[0007] An inner liner main body, a fixed seat, and a locking member;
[0008] The inner liner main body has a receiving space, as well as a first opening and a first through hole communicating with the receiving space. The inner wall of the receiving space has a guide rail;
[0009] The fixed seat is connected to the inner liner main body within the receiving space, and the fixed seats are distributed at positions of the guide rail close to the end of the first opening. The fixed seat has a guide wheel cooperating with the guide rail;

[0038] To make the purpose, technical solutions and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the drawings.
[0039] Please refer to Figure 1 、Figure 2 and Figure 3 , Figure 1 is a schematic diagram of an inner liner structure of a box body provided by an embodiment of the present application, Figure 2 is Figure 1 a partial enlarged view of an inner liner of a box body at A shown, Figure 3 is a schematic diagram of a structure of a fixing seat and a locking member provided by an embodiment of the present application. The inner liner 000 of the box body may include: an inner liner main body 100, a fixing seat 200, and a locking member 300.
[0040] The inner liner main body 100 in the inner liner 000 of the box body may have a receiving space C, as well as a first opening K1 and a first through hole M1 communicating with the receiving space C. Among them, the inner wall of the receiving space C may have a guide rail 101.
[0041] The fixing seat 200 in the inner liner 000 of the box body is connected to the inner liner main body 100 in the receiving space C, and the fixing seats 200 are distributed at the position where the end of the guide rail 101 close to the first opening K1 is located. The fixing seat 200 has a guide wheel 201 that cooperates with the guide rail. That is to say, the guide wheel 201 may be located at the position where the end of the guide rail 101 close to the first opening K1 is located. In this way, the drawer can be pulled out of the receiving space C of the inner liner 000 of the box body or received into the receiving space C of the inner liner 000 of the box body through the cooperation of the guide wheel 201 and the guide rail 101.
[0042] The locking member 300 in the inner liner 000 of the box body is located outside the receiving space C, and the locking member 300 is connected to the fixing seat 200 through the first through hole M1. In this way, the fixing seat 200 can be firmly fixed on the inner liner 000 of the box body through the locking member 300.
[0043] In the present application, one side of the locking member 300 in the inner liner 000 of the box body facing the inner liner main body 100 may have a sealing portion 301 that abuts against the outer wall of the inner liner main body 100.
[0044] Generally, during the manufacturing process of a refrigeration device, it is necessary to inject a foaming agent between the inner liner of the box body and the outer shell. Through the expansion and curing of the foaming agent, a layer of foamed plastic is formed, so as to achieve effects such as heat insulation, sound insulation, and moisture protection. The foam formed by foaming can effectively block the transfer of external heat and cold, and improve the heat preservation performance of the refrigeration device. However, since there will be a certain gap between the fixing seat 200 and the inner liner 000 of the box body after assembly, during the process of injecting the foaming agent, the foaming agent will leak from the gap between the fixing seat 200 and the inner liner 000 of the box body into the receiving space C of the inner liner 000 of the box body, resulting in uneven thickness of the heat preservation layer, affecting the overall heat preservation performance of the refrigeration device, and increasing energy consumption.
[0045] Therefore, after the fixed seat 200 and the inner container liner 000 of the box are assembled, the operator needs to tape-seal the assembly position of the fixed seat 200 and the inner container liner 000 to prevent the foaming agent from leaking into the accommodation space C of the inner container liner 000 from the connection position between the fixed seat 200 and the inner container liner 000 during the process of injecting the foaming agent between the inner container liner 000 and the outer shell.
[0046] In the embodiment of the present application, the locking member 300 is connected to the fixed seat 200 through the first through hole M1, and the sealing portion 301 in the locking member 300 abuts against the inner container main body 100. In this way, after the sealing portion 301 abuts against the inner container main body 100, an extrusion force is formed between the sealing portion 301 and the inner container main body 100, so that elastic deformation occurs at the contact position between the sealing portion 301 and the inner container main body 100, and thus a better seal can be formed between the fixed seat 200 and the inner container main body 100. Therefore, during the process of injecting the foaming agent into the refrigeration device, the foaming agent will not enter the accommodation space C of the inner container main body 100 from the gap between the fixed seat 200 and the inner container main body 100. In this way, there is no need to tape-seal the gap between the fixed seat 200 and the inner container main body 100, which makes the assembly of the inner container liner 000 of the box simpler, and the process of taping is reduced, which can improve the assembly efficiency of the inner container liner 000 of the box.
[0047] In summary, the embodiment of the present application provides an inner container liner of a box and a refrigeration device, including: an inner container main body, a fixed seat, and a locking member. The locking member is connected to the fixed seat through the first through hole, and the sealing portion in the locking member abuts against the inner container main body. In this way, after the sealing portion abuts against the inner container main body, an extrusion force is formed between the sealing portion and the inner container main body, so that elastic deformation occurs at the contact position between the sealing portion and the inner container main body, and thus a better seal can be formed between the fixed seat and the inner container main body. Therefore, during the process of injecting the foaming agent into the refrigeration device, the foaming agent will not enter the accommodation space of the inner container main body from the gap between the fixed seat and the inner container main body. In this way, there is no need to tape-seal the gap between the fixed seat and the inner container main body, which makes the assembly of the inner container liner of the box simpler, and the process of taping is reduced, which can improve the assembly efficiency of the inner container liner of the box.
[0048] Exemplarily, the sealing portion 301 in the locking member 300 can be annular, and the sealing portion 301 is distributed around the first through hole M1.
[0049] In this way, since the sealing portion 301 is annular and distributed around the first through hole M1, the annular sealing portion 301 can seal the gap between the fixed seat 200 and the inner container main body 100 in all directions, further enhancing the sealing effect and ensuring that the foaming agent will not leak from the gap between the fixed seat 200 and the inner container main body 100.
[0050] Optionally, please refer toFigure 4 , Figure 4 It is a schematic structural diagram of another fixing seat and locking member provided by an embodiment of the present application. The fixing seat 200 in the inner liner 000 of the box body may have a connecting rod 202 that matches the first through hole M1, and the connecting rod 202 extends outside the accommodation space C through the first through hole M1.
[0051] Among them, the locking member 300 in the inner liner 000 of the box body is connected to the part of the connecting rod 202 that extends outside the accommodation space C.
[0052] In this case, through the precise cooperation between the connecting rod 202 and the locking member 300, the assembly accuracy between the fixing seat 200 and the inner liner main body 100 is improved, ensuring the stability of the entire structure.
[0053] In the embodiment of the present application, the locking member 300 in the inner liner 000 of the box body is threadedly connected to the part of the connecting rod 202 that extends outside the accommodation space C.
[0054] For example, the locking member 300 has an internal thread hole, the connecting rod 201 is provided with a matching external thread, and the connecting rod 201 is connected to the internal thread hole of the locking member 300 through its external thread.
[0055] In this way, through the threaded connection, the connection between the locking member 300 and the connecting rod 202 can be made more stable and reliable, ensuring the structural stability between the fixing seat 200 and the inner liner main body 100.
[0056] It should be noted that in other possible implementation manners, the side of the locking member 300 facing the inner liner main body 100 may also have a screw rod with an external thread, and the fixing seat 200 may have a thread hole that is threadedly connected to the screw rod. In this way, through the threaded connection between the screw rod on the locking member 300 and the thread hole on the fixing seat 200, the stable connection between the locking member 300 and the fixing seat 200 can also be achieved.
[0057] Optionally, as Figure 4 shown, the locking member 300 in the inner liner 000 of the box body may include: a sealing portion 301, a locking member body 302, and a plurality of handle portions 303.
[0058] Among them, the sealing portion 301 in the locking member 300 is fixedly connected to the side of the locking member body 302 facing the inner tank body 100, and a plurality of handle portions 303 are circumferentially distributed on the outer periphery of the locking member body 302. By way of example, the number of the plurality of handle portions 303 is four, and the four handle portions 303 are evenly distributed on the outer periphery of the locking member body 302. In this way, by arranging a plurality of handle portions 303 to be circumferentially distributed on the outer periphery of the locking member body 302, an operator can more conveniently apply a rotational force to the locking member 300, so that the locking member 300 can be more conveniently assembled on the portion of the connecting rod 202 extending out of the accommodating space C or removed from the connecting rod 202.
[0059] In the embodiments of the present application, please refer to Figure 4 、 Figure 5 and Figure 6 , Figure 5 which is a schematic structural diagram of a fixing seat provided by the embodiments of the present application, Figure 6 is Figure 1 Another partial enlarged view of the inner tank of the box at A shown. The fixing seat 200 in the inner tank 000 of the box may include: a fixing seat body 203, and a guide wheel 201 connected to the fixing seat body 203.
[0060] The fixing seat body 203 in the fixing seat 200 may further have a first limiting groove P1, and the end of the guide rail 101 close to the first opening K1 has a protruding portion Q1 matching the first limiting groove P1.
[0061] Among them, at least a part of the protruding portion Q1 in the guide rail 101 is located in the first limiting groove P1.
[0062] In this case, by setting the first limiting groove P1 to match the protruding portion Q1 of the guide rail 101, at least a part of the protruding portion Q1 in the guide rail 101 is located in the first limiting groove P1, thereby improving the connection stability between the fixing seat 200 and the guide rail 101 and preventing the fixing seat 200 from being displaced or loosened during use.
[0063] Optionally, as Figure 6 shown, the inner wall of the accommodating space C in the inner tank 000 of the box further has a second limiting groove P2 matching the outer shape of the fixing seat body 203.
[0064] Among them, a part of the fixing seat body 203 in the fixing seat 200 is located in the second limiting groove P2. In this way, by setting the second limiting groove P2 to match the outer shape of the fixing seat body 203, a part of the fixing seat body 203 is located in the second limiting groove P2, thereby improving the positioning accuracy and stability of the fixing seat 200 in the accommodating space C and further preventing it from being offset or shaken during use.
[0065] In the embodiments of the present application, please refer to Figure 4 In this case, the fixing base body 203 in the fixing base 200 may further have a connection hole M2. The guide wheel 201 in the fixing base 200 may include: a guide wheel body 2011 and a connection rotating shaft 2012 connected to the guide wheel body 2011.
[0066] Among them, at least a part of the connection rotating shaft 2012 in the guide wheel 201 that is not connected to the guide wheel body 2011 is located in the connection hole M2.
[0067] In this way, by having at least a part of the connection rotating shaft 2012 in the guide wheel 201 that is not connected to the guide wheel body 2011 located in the connection hole M2, the installation of the guide wheel 201 on the fixing base body 203 can be made more stable, and at the same time, it is ensured that the guide wheel 201 can rotate smoothly, thereby improving the reliability of the guide wheel 201.
[0068] Optionally, please refer to Figure 6 In this case, the inner wall of the accommodation space C in the inner box liner 000 further has a blind hole A communicating with the connection hole M2.
[0069] Among them, the end of the connection rotating shaft 2012 in the guide wheel 201 passes through the connection hole M2 and is located in the blind hole A.
[0070] In this case, by having the end of the connection rotating shaft 2012 in the guide wheel 201 pass through the connection hole M2 and be located in the blind hole A, the installation of the guide wheel 201 can be made more stable, and at the same time, the connection rotating shaft 2012 can be prevented from falling off during use, thereby further improving the reliability of the guide wheel 201.
[0071] In summary, the embodiments of the present application provide an inner box liner and a refrigeration device, including: an inner liner main body, a fixing base, and a locking member. The locking member is connected to the fixing base through a first through hole, and the sealing portion in the locking member abuts against the inner liner main body. In this way, after the sealing portion abuts against the inner liner main body, an extrusion force is formed between the sealing portion and the inner liner main body, so that elastic deformation occurs at the contact position between the sealing portion and the inner liner main body, and further a better seal can be formed between the fixing base and the inner liner main body. Therefore, during the process of filling the refrigeration device with foaming agent, the foaming agent will not enter the accommodation space of the inner liner main body from the gap between the fixing base and the inner liner main body. In this way, it is not necessary to use adhesive tape to block the gap between the fixing base and the inner liner main body, thereby making the assembly of the inner box liner simpler, and reducing the process of applying adhesive tape can improve the assembly efficiency of the inner box liner.
