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 refrigerator door body 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 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 refrigerator door body at the initial stage cannot destroy 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 refrigerator door body, 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 refrigerator door body, the more obvious the decrease in air pressure.

[0003] As can be seen from the above, due to the existence of the pressure difference between the inside and outside of the refrigerator door body, a certain force needs to be overcome when the refrigerator door 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 refrigerator door is opened. In this way, for a refrigerator with a low refrigeration temperature (especially the freezer) and a large refrigerator door body, 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

[0019] Wherein, the power arm between the button and the connecting rod pin is smaller than the power arm between the connecting rod pin and the wedge block.

[0020] It can be understood that through the above structural settings, the driving component can, by the lever principle, drive the button to finally drive the wedge block to slide on the door body when the button is pressed, achieving the purpose of saving effort.

[0021] In one embodiment, the driving component further includes an elastic member, which is abutted between the connecting rod and the door body in a pre-deformed manner to drive the connecting rod to elastically reset.

[0022] In one embodiment, a handle is formed on the door body, and the handle can be grasped by a human hand;

[0023] Among them, the button is arranged at the position where the handle is located.

[0024] It can be understood that arranging the button at the position where the handle is located enables the user to drive the button when opening the refrigerator door with the handle, which is convenient for the user to operate the button.

[0025] In one embodiment, the handle is formed with a concave cavity inward, and the concave cavity can allow a human hand to extend in;

[0026] Among them, the button protrudes outward relative to a part of the door body, and the part of the button protruding from the door body is arranged in the concave cavity.

[0027] It can be understood that through the above structural settings, on the one hand, the handle can hide the button, so that the setting of the button will not affect the appearance of the refrigerator door body, and on the other hand, the handle can also protect the button to prevent the button from being accidentally triggered.

[0028] In addition, the present application also claims protection for a refrigerator, including a box body and the refrigerator door body described above, and the refrigerator door body is movably installed on the box body.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0042] like Figure 1 , Figure 3 As shown, the refrigerator door body 100 provided in the present application includes a door body 10, a door seal 20 and a door opening assist mechanism 30, wherein the door body 10 is used to be movably mounted on the housing 200; the door seal 20 is arranged on the inner side of the door body 10 and is connected to the door body 10, and the door body 10 can be assembled and sealed with the housing 200 through the door seal 20; the door opening assist mechanism 30 is movably mounted on the door body 10, and the door opening assist mechanism 30 includes a driving assembly 31 and a wedge block 32, the wedge block 32 is slidably mounted on the door body 10 and is transmission-connected to the driving assembly 31, and the wedge block 32 can squeeze the door seal 20 under the drive of the driving assembly 31, so as to release the seal between the door body 10 and the housing 200 by the door seal 20.

[0043] From the above, it can be seen that the refrigerator door body 100 of the present application is applied to the refrigerator, and the wedge block 32 can be used to squeeze the door seal 20 to destroy the seal between the door body 10 and the box body 200. This can eliminate the internal and external pressure difference of the refrigerator door body 100, thereby realizing the labor-saving door opening of the refrigerator using the refrigerator door body 100 and improving the user experience.

[0044] like Figure 4 , Figure 5 As shown, the driving assembly 31 includes a button 311 and a connecting rod 312, the connecting rod 312 is rotatably connected to the door body 10, one end of the connecting rod 312 is rotatably connected to the wedge block 32, and the other end of the connecting rod 312 is rotatably connected to the button 311, so that the button 311 can drive the wedge block 32 to slide on the door body 10 through the connecting rod 312, so as to control whether the wedge block 32 squeezes the door seal 20, so as to achieve the purpose of whether to destroy the seal between the door body 10 and the box body 200. In other words, the user can control the sliding of the wedge block 32 on the door body 10 by pressing the button 311, and finally achieve the purpose of destroying the seal between the door body 10 and the box body 200. Here, the connecting rod 312 and the button 311 and the wedge block 32 can also be assembled with a pin shaft 301 respectively, and finally realize the rotation connection between the connecting rod 312 and the button 311 and the wedge block 32.

[0045] As preferably, Figure 4 , Figure 5As shown in the figure, the connecting rod 312 is rotatably connected to the door body 10 through a connecting rod pin 3121; among them, the power arm between the button 311 and the connecting rod pin 3121 is smaller than the power arm between the connecting rod pin 3121 and the wedge block 32. So that the driving assembly 31 can, through the lever principle, drive the wedge block 32 to slide on the door body 10 when the button 311 is pressed, and achieve the purpose of saving effort, which can further facilitate the user to drive the driving assembly 31.

[0046] As Figures 1 to 4 shown in the figure, a handle 11 is formed on the door body 10, and the handle 11 can be grasped by a human hand; among them, the button 311 is arranged at the position where the handle 11 is located, so that when the user opens the refrigerator door body 100 with the handle 11, the button 311 can be driven, which can facilitate the user to operate the button 311.

[0047] Preferably, as Figure 2 、 Figure 4 shown in the figure, the handle 11 is formed with a concave cavity 111 inwardly, and the concave cavity 111 can be penetrated by a human hand; among them, the button 311 protrudes outward relative to the door body 10, and the part of the button 311 protruding from the door body 10 is arranged in the concave cavity 111. That is to say, the handle 11 can block the button 311, so that on the one hand, the handle 11 can hide the button 311, so that the setting of the button 311 will not affect the appearance of the refrigerator door body 100, and on the other hand, the handle 11 can also protect the button 311 to prevent the button 311 from being accidentally triggered.

[0048] As Figures 3 to 5 shown in the figure, the driving assembly 31 further includes an elastic member 313, and the elastic member 313 abuts between the connecting rod 312 and the door body 10 in a pre-deformed manner, and is used to drive the connecting rod 312 to elastically reset. That is to say, when the human hand releases the driving of the button 311, the elastic member 313 can be used to automatically drive the connecting rod 312 to reset to meet the user's use requirement of repeatedly driving the wedge block 32 with the driving assembly 31. Here, the elastic member 313 is configured as a compression spring, a torsion spring, a high-elasticity fitting, etc. It can be understood that how the elastic member 313 is assembled on the connecting rod 312 can be specifically set according to the use requirements, and will not be elaborated here.

[0049] As Figure 3 、 Figure 4As shown, the wedge block 32 can be inserted between the door seal 20 and the cabinet 200 to squeeze the door seal 20 to undergo elastic deformation. That is to say, the wedge block 32 of the present application can squeeze the door seal 20 to undergo elastic deformation by being inserted between the door seal 20 and the cabinet 200, which can avoid the influence of the existence of the wedge block 32 on the assembly of the door seal 20 on the door body 10 and ensure the stability of the assembly of the door seal 20 on the door body 10.

[0050] Preferably, as Figure 4 shown, when the door body 10 is assembled and sealed with the cabinet 200 through the door seal 20, part of the wedge block 32 abuts against the door seal 20. That is to say, when the wedge block 32 does not release the seal between the door body 10 and the cabinet 200 by the door seal 20, the wedge block 32 abuts against the door seal 20, which can improve the smoothness of the extrusion of the door seal 20 when the wedge block 32 slides on the door body 10 and ensure that the wedge block 32 can compress the door seal 20 to undergo elastic deformation.

[0051] As Figure 5 shown, a chute 321 is formed on the wedge block 32. The chute 321 can be inserted and matched with the door body 10 and guide the wedge block 32 to slide on the door body 10. This can ensure the consistency of the direction when the wedge block 32 slides on the door body 10 to meet the use requirement that the wedge block 32 can realize the extrusion of the door seal 20 during the sliding process.

[0052] As Figure 6 shown, the present application further provides a refrigerator, including a cabinet 200 and the refrigerator door body 100 described above. The refrigerator door body 100 is movably installed on the cabinet 200.

[0053] In summary, when the user opens the refrigerator door body 100 of the refrigerator, the user can press the button 311. Using the lever principle, under the transmission of the connecting rod 312, the driving of the wedge block 32 to slide on the door body 10 can be realized, so as to squeeze the door seal 20 to undergo elastic deformation by the wedge block 32 and release the seal between the door body 10 and the cabinet 200, which can reduce the opening force of the refrigerator door body 100 and play a role in facilitating the user to open the door.
