Description

Technical Field

[0001] The utility model belongs to the technical field related to the opening of a refrigerator door, and particularly relates to a door body assembly and a refrigerator. Background Art

[0002] After the refrigerator is refrigerated, the internal temperature of the refrigerator body decreases. In this case, with the space remaining unchanged, according to the formula: PV = nRT (P: pressure; V: volume; n: amount of substance; T: temperature), when the internal air temperature of the box body decreases, the internal air pressure inside the box body will decrease and be lower than the external atmospheric pressure. In addition, when the refrigerator door is opened, due to the existence of the door seal (with a certain elastic deformation amount), a small displacement of the door body assembly at the initial stage cannot break the sealing of the internal space. At this time, the internal temperature of the box body remains unchanged and the volume increases. Among them, the formula is: △V = Sd (S is the inner surface area of the door body assembly, and d is the displacement amount for the door seal to maintain the seal). The internal air pressure of the box body further decreases, and the larger the door body assembly, the more obvious the decrease in air pressure.

[0003] As can be seen from the above, due to the existence of the pressure difference inside and outside the door body assembly, a certain force needs to be overcome when the door body assembly is opened. According to F = △PS (the pressure against the opening force at this time is the internal and external air pressure difference), the greater the pressure difference, the more difficult it is to open the door. In addition, the door guide rail usually has a certain self-locking force to achieve automatic door closing within a certain distance. The larger the door body (the greater the weight), the greater the required self-locking force of the guide rail, which becomes another resistance when the door body assembly is opened. In this way, for a refrigerator with a low refrigeration temperature (especially the freezer) and a large door body assembly, the opening force is usually very large, which is not convenient for users to open the door. Moreover, for the elderly, children, and women, it will be particularly strenuous to open the refrigerator door. Summary of the Utility Model

[0004] In view of this, it is necessary to provide a door body assembly and a refrigerator for solving the above technical problems.

[0005] A door body assembly, the door body assembly includes:

[0006] A door body, which is movably installed on the inner liner. A door seal is installed on the door body, and the door body can be assembled and sealed with the outer edge of the inner liner through the door seal;

[0007] A dial, which is rotatably installed on the door body. The dial partially protrudes outward relative to the door body and can be pressed by a human hand;

[0008] A push rod, which is slidably installed inside the door body and rotatably connected to the dial. Along the thickness direction of the door body, the push rod can protrude from the door body towards the inner liner under the drive of the dial and push the inner edge of the inner liner to release the seal between the door seal and the outer edge of the door body.

[0009] It can be understood that through the above structural arrangement, when the door body assembly is applied to a refrigerator and needs to be opened from the inner liner, a person's hand can press the paddle to drive the ejector rod to push against the inner edge of the inner liner. By using the action and reaction forces, the part of the door seal close to the ejector rod can be pried open, so as to eliminate the internal and external pressure difference of the door body assembly, thereby realizing labor-saving opening of the door body assembly and improving the user experience.

[0010] In one embodiment, a first arc surface is formed on the paddle, and a second arc surface is formed on the ejector rod. The second arc surface abuts against the first arc surface, and the paddle can push the second arc surface through the first arc surface to drive the ejector rod to extend out of the door body.

[0011] It can be understood that since the force is transmitted between the paddle and the ejector rod through the abutment between the first arc surface and the second arc surface, this can avoid stress concentration when the paddle pushes the ejector rod, thereby ensuring the smoothness of the force transmission between the paddle and the ejector rod and preventing the structure of the paddle and / or the ejector rod from being damaged during the force transmission process.

[0012] In one embodiment, an extension convex plate is formed on the ejector rod. The extension convex plate can be inserted and matched with the paddle and is rotatably connected to the paddle by a first pin;

[0013] Wherein, the second arc surface is arranged on the extension convex plate.

[0014] It can be understood that through the above structural arrangement, it is convenient for the assembly connection between the ejector rod and the paddle, and it is ensured that the ejector rod uses the second arc surface to transmit force with the paddle.

[0015] In one embodiment, a buffer is installed on the ejector rod, and the ejector rod can push against the inner edge through the buffer.

[0016] It can be understood that the buffer is used to buffer when the ejector rod pushes against the inner edge, so as to prevent the inner edge of the inner liner from being scratched during the process of the ejector rod pushing.

[0017] In one embodiment, the paddle is rotatably connected to the door body by a second pin;

[0018] Wherein, the paddle has a first part and a second part. The first part is arranged above the second pin and partially extends out of the door body. The second part is arranged below the second pin, and the length of the first part is less than the length of the second part.

[0019] It can be understood that through the above structural arrangement, a person's hand can drive the rotation of the paddle on the door body through the lever principle, thus achieving the purpose of saving effort.

[0020] In one embodiment, the door body assembly further includes an elastic member, which is abutted between the paddle and the door body in a pre-deformed manner for driving the paddle to elastically reset.

[0021] It can be understood that by using the elastic pushing of the elastic member on the paddle, the automatic reset of the paddle after losing external force can be realized, thus meeting the user's usage requirement of repeatedly driving the paddle.

[0022] In one embodiment, the number of the ejector rods is configured to be two, and the number of the paddles is configured to be one;

[0023] Along the length direction of the paddle, the two ejector rods are arranged on both sides of the paddle.

[0024] It can be understood that through the above structural arrangement, when a person's hand presses the paddle, the two ejector rods can be driven to push against the inner edge of the inner container at the same time, thus ensuring that the part of the door seal close to the ejector rod can be pried open.

[0025] In one embodiment, a handle is formed on the door body, and the handle can be grasped by a person's hand;

[0026] Wherein, the paddle is arranged at the position where the handle is located.

[0027] It can be understood that by arranging the paddle at the position where the handle is located, when the user opens the door body assembly with the handle, the paddle can be pressed incidentally, thus facilitating the user's operation of opening the door body assembly.

[0028] In one embodiment, a concave cavity is formed between the handle and the door body, and the concave cavity can allow a person's hand to extend into it;

[0029] Wherein, the paddle extends outwards relative to the door body in part, and the part of the paddle extending out from the door body is arranged in the concave cavity.

[0030] It can be understood that through the above structural arrangement, on the one hand, the handle can hide the paddle, so that the setting of the paddle does not affect the appearance of the door body assembly, and on the other hand, the handle can protect the paddle to prevent the paddle from being accidentally triggered.

[0031] In addition, the present application also provides a refrigerator, including an inner container and the above-mentioned door body assembly, and the door body assembly is movably installed on the inner container.

[0032] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0046] As Figure 6 shown, the door body assembly 100 claimed in the present application is applied to a refrigerator and is used to selectively cover the inner liner 200 of the refrigerator.

[0047] As Figures 1 to 3 、 Figure 7 shown, the door body assembly 100 provided by the present application includes a door body 10, a dial 20 and a push rod 30. The door body 10 is movably installed on the inner liner 200. A door seal 11 is installed on the door body 10, and the door body 10 can be assembled and sealed with the outer edge 210 of the inner liner 200 through the door seal 11. The dial 20 is rotatably installed on the door body 10, and the dial 20 partially protrudes outward relative to the door body 10 and can be pressed by hand. The push rod 30 is slidably installed in the door body 10 and is rotatably connected to the dial 20. Along the thickness direction of the door body 10, the push rod 30 can protrude from the door body 10 towards the inner liner 200 under the drive of the dial 20 and push against the inner edge 220 of the inner liner 200 to release the seal between the door seal 11 and the outer edge 210 of the door body 10. Here, the inner liner 200 is a conventional structure in an existing refrigerator, and the distance between the outer edge 210 and the inner edge 220 of the inner liner 200 is very close. And the push rod 30 can be specifically arranged adjacent to one side corner of the door seal 11.

[0048] As described above, when the door body assembly 100 is applied to a refrigerator and the ice needs to be opened from the inner liner 200, a person's hand can press the paddle 20 to drive the ejector rod 30 to push against the inner edge 220 of the inner liner 200. Using the action and reaction forces, the part of the door seal 11 close to the ejector rod 30 can be pried open, so as to eliminate the internal and external pressure difference of the door body assembly 100, thereby realizing labor-saving opening of the door body assembly 100 and improving the user experience.

[0049] As Figure 2 , Figure 3 shown, a handle 12 is formed on the door body 10, and the handle 12 can be grasped by a person's hand. That is to say, the handle 12 on the door body 10 is the acting part when the user opens the door body assembly 100 from the inner liner 200. Here, the paddle 20 is arranged at the position where the handle 12 is located, so that when the user opens the door body assembly 100 with the handle 12, the paddle 20 can be pressed incidentally. That is, the user can complete pressing the paddle 20 and pulling the handle 12 with a person's hand together, which is convenient for the user to perform the door opening operation on the door body assembly 100.

[0050] Preferably, as Figure 3 shown, a concave cavity 101 is formed by enclosing between the handle 12 and the door body 10, and the concave cavity 101 can accommodate a person's hand to reach in; wherein, the paddle 20 extends outward relative to a part of the door body 10, and the part of the paddle 20 extending out from inside the door body 10 is arranged in the concave cavity 101. That is to say, the handle 12 can block the part of the paddle 20 extending out of the door body 10, so that on the one hand, the handle 12 can hide the paddle 20, so that the setting of the paddle 20 will not affect the appearance of the door body assembly 100, and on the other hand, the handle 12 can also protect the paddle 20 to prevent the paddle 20 from being accidentally triggered.

[0051] As Figure 4 shown, the number of the paddles 20 in this application is configured as one, and the number of the ejector rods 30 is configured as two. The two ejector rods 30 are arranged on both sides of the paddle 20 along the length direction of the paddle 20, so that when a person's hand presses the paddle 20, the two ejector rods 30 can be driven to push against the inner edge 220 of the inner liner 200 at the same time, so as to ensure that the part of the door seal 11 close to the ejector rod 30 can be pried open. Here, the paddle 20 extends along the handle 12.

[0052] As Figure 3 , Figure 5As shown, the paddle 20 is rotatably connected to the door body 10 through a second pin 104. Among them, the paddle 20 has a first part 201 and a second part 202. The first part 201 is disposed above the second pin 104 and partially extends out of the door body 10. The second part 202 is disposed below the second pin 104. Moreover, the length of the first part 201 is less than the length of the second part 202. That is to say, a person can drive the rotation of the paddle 20 on the door body 10 by pressing the first part 201 on the paddle 20. During this process, by using the fact that the length of the first part 201 is less than the length of the second part 202, a person can drive the rotation of the paddle 20 on the door body 10 through the lever principle. During this process, the ejector rod 30 extends out of the door body 10 under the drive of the paddle 20 and pushes against the inner edge 220 of the inner tank 200, so as to achieve the purpose of saving effort.

[0053] As Figure 3 , Figure 5 shown, a first arc surface 211 is formed on the paddle 20, and a second arc surface 311 is formed on the ejector rod 30. The second arc surface 311 abuts against the first arc surface 211. Moreover, the paddle 20 can push against the second arc surface 311 through the first arc surface 211 to drive the ejector rod 30 to extend out of the door body 10. That is to say, the paddle 20 can contact the ejector rod 30 in the form of an arc surface and conduct force transmission, so as to avoid stress concentration when the paddle 20 pushes against the ejector rod 30, thereby ensuring the smoothness of force transmission between the paddle 20 and the ejector rod 30 and preventing the paddle 20 and / or the ejector rod 30 from being damaged in structure during the process of force transmission. Here, the first arc surface 211 is concave, and the second arc surface 311 is convex.

[0054] As Figure 5 shown, an extension convex plate 31 is formed on the ejector rod 30. The second arc surface 311 is disposed on the extension convex plate 31. The extension convex plate 31 can be inserted and matched with the paddle 20 and is rotatably connected to the paddle 20 by a first pin 102. That is to say, the ejector rod 30 can first be inserted and matched with the paddle 20 by the extension convex plate 31, and then be inserted and limited by the first pin 102, so as to facilitate the assembly connection between the ejector rod 30 and the paddle 20 and ensure that the ejector rod 30 conducts force transmission with the paddle 20 through the second arc surface 311.

[0055] As Figure 5As shown, a connecting seat 21 is formed on the paddle 20. The connecting seat 21 can be inserted by the extending convex plate 31 and limited by inserting the first pin 102. Here, a limit pin 103 is inserted on the part of the first pin 102 passing through the connecting seat 21 to limit the first pin 102 to the connecting seat 21 and prevent the first pin 102 from falling off the connecting seat 21. In this way, the assembly limit of the first pin 102 between the connecting seat 21 and the extending convex plate 31 can be realized to meet the use requirement of the rotational connection between the ejector rod 30 and the paddle 20. Here, the limit pin 103 is connected to the first pin 102 in an interference fit manner.

[0056] As Figure 3 , Figure 5 shown, a buffer member 32 is installed on the ejector rod 30, and the ejector rod 30 can push against the inner edge 220 through the buffer member 32. That is to say, the door body assembly 100 can utilize the structural characteristics of the buffer member 32 to play a buffering role when the ejector rod 30 pushes against the inner edge 220, so as to avoid scratching the inner edge 220 of the inner container 200 during the pushing process of the ejector rod 30. Here, the buffer member 32 is configured as a rubber sleeve, and the rubber sleeve is assembled to the ejector rod 30 in a sleeved manner. It can be understood that in other embodiments, the material of the buffer member 32 can also be configured as silica gel, nitrile rubber, polyurethane, polypropylene rubber or neoprene.

[0057] As Figures 3 to 5 shown, the door body assembly 100 further includes an elastic member 40. The elastic member 40 abuts against the paddle 20 and the door body 10 in a pre-deformed manner to drive the paddle 20 to elastically reset. That is to say, when the paddle 20 loses the pressing drive of the human hand, the paddle 20 can automatically reset under the pushing of the elastic member 40, which creates conditions for the next pressing drive of the paddle 20 and meets the user's use requirement of repeatedly driving the paddle 20. Here, the elastic member 40 is configured as a torsion spring. The torsion spring is assembled into the door body 10, and one elastic arm of the torsion spring is inserted into the paddle 20. It can be understood that in other embodiments, the elastic member 40 can also be configured as a compression spring, etc.

[0058] As Figure 6 shown, the present application also provides a refrigerator, including an inner container 200, and the above-mentioned door body assembly 100. The door body assembly 100 is movably installed on the inner container 200.

[0059] In summary, when the user opens the door body assembly 100 of the refrigerator, the user can first press the first part 201 of the paddle 20 with the human hand. Using the principle of the lever, drive the ejector rod 30 to push against the inner edge 220 of the inner container 200, and then use the action and reaction forces to break the seal between the door body 10 and the outer edge 210 of the inner container 200, so as to reduce the opening force required when opening the door body assembly 100 and facilitate the user to open the door.

[0060] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0061] Those of ordinary skill in the art in this technical field should recognize that the above embodiments are only used to illustrate the present utility model, rather than to limit the present utility model. As long as it is within the scope of the essential spirit of the present utility model, the appropriate changes and variations made to the above embodiments fall within the scope of protection required by the present utility model.
