Description

Technical Field

[0001] The utility model belongs to the technical field related to household appliances, and particularly relates to a refrigerator. Background Art

[0002] With the fast-paced life, people have gradually developed the shopping habit of regularly purchasing items and storing them. Warehouse-style large supermarkets are especially popular among young people. To keep large quantities of bread, desserts, fruits, and meats fresh for a certain period of time, freshness preservation and large capacity have become the trend of refrigerators. The convenience of taking large-boxed foods in and out of the refrigerator has gradually become an important factor to be considered in refrigerator design. Generally, an opening angle of more than 90° is required to ensure that the drawer can be fully pulled out without interference. However, considering that too large an opening angle may cause the embedded refrigerator to collide with the wall when the door is opened. The contradiction between the two user requirements of a large opening angle and embedded cabinet installation has increased the difficulty of refrigerator design.

[0003] Currently, the opening of existing refrigerators is mainly achieved by hinges. The opening and closing angle of the hinges directly determines the maximum opening and closing angle of the door body. Although the opening angle of the refrigerator door is greater than 90° to ensure that the drawer can be fully pulled out without interference, and the function of normally taking and placing items can be realized by pulling and closing the refrigerator drawer. However, when accessing items in a refrigerator with a 90° opening, the user's activity space is limited. Especially for large or irregularly shaped items, it is often necessary to repeatedly search for a suitable storage position and flipping angle in a limited space to complete the storage of the items. Moreover, for the internal space of the refrigerator, the user's visibility is low, resulting in a decrease in the utilization rate of the internal space and often forgetting the items stored on the refrigerator shelf and inside the bottle holder. Summary of the Utility Model

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

[0005] A refrigerator includes a box body, a door body, and a connecting mechanism. The door body is connected to the box body through the connecting mechanism. The connecting mechanism includes:

[0006] A guide rail assembly, including a guide rail seat and a telescopic rod. The guide rail seat is fixedly installed on the box body and is slidably connected to the telescopic rod.

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

[0036] The refrigerator 100 claimed in this application specifically refers to a double-door refrigerator.

[0037] As Figures 1 to 3As shown in the figure, the refrigerator 100 provided by the present application includes a box body 10, a door body 20, and a connecting mechanism 30. The door body 20 is connected to the box body 10 through the connecting mechanism 30. The connecting mechanism 30 includes a guide rail assembly 31 and a door hinge 32. The guide rail assembly 31 includes a guide rail seat 311 and a telescopic rod 312. The guide rail seat 311 is fixedly installed on the box body 10 and is slidably connected to the telescopic rod 312. Among them, the telescopic rod 312 has a free end 3121, and the free end 3121 can extend out of the box body 10 along the width direction of the refrigerator 100 under the drive of the telescopic rod 312. The door hinge 32 includes a first hinge piece 321 and a second hinge piece 322 that are rotatably connected. The first hinge piece 321 is fixedly connected to the free end 3121, and the second hinge piece 322 is fixedly connected to the door body 20. It should be noted that the conventional method of the existing guide rail can be adopted for the sliding connection between the telescopic rod 312 and the guide rail seat 311, and no further elaboration will be made here.

[0038] As can be seen from the above, the door body 20 on the refrigerator 100 of the present application realizes door opening through the linkage of the guide rail assembly 31 and the door hinge 32, so that the door body 20 can move in two directions of sliding and rotation during the door opening process, and the door body 20 can be turned outside the box body 10, which can increase the maximum door opening angle of the door body 20 on the refrigerator 100 and maximize the visibility of the internal space of the box body 10, so that users have a larger operating space and a broader view when storing and retrieving items. Here, when the door body 20 is opened outside the box body 10, the user can directly see the completely open storage space inside the box body 10, avoiding the deterioration of items stored in the corner of the refrigerator for a long time due to being forgotten. For items smaller than the width, depth, and height of the box body 10, users have a larger operating space when storing and taking them.

[0039] It should be noted that within the maximum sliding distance when the refrigerator 100 of the present application slides on the guide rail seat 311 and within the maximum rotation angle range between the first hinge piece 321 and the second hinge piece 322 in the door hinge 32, the opening degree of the door body 20 can be controlled personalized, which can solve the limitation of the door opening angle on the user's operating space.

[0040] In the present application, the box body 10 is configured as a refrigerating box body. That is to say, the refrigerator 100 has a larger operating space and a broader view during the door opening process of the refrigerating chamber. It can be understood that in other embodiments, the box body 10 can also be configured as a freezing box body, a fresh-keeping box body, etc., and no further elaboration will be made here.

[0041] In this application, the number of door bodies 20 is configured to be two, and each door body 20 is connected to the box body 10 through a connecting mechanism 30. That is to say, the refrigerator 100 is configured as a double-door refrigerator. It should be noted that a door body bottle holder 21 is assembled on the door body 20, and the door body bottle holder 21 can be used to store fragile and toppling items such as eggs, beverages, and seasonings, so as to maximize the storage space of the box body 10. The door body 20 of this application can be flipped on the box body 10 through a door hinge 32, so that the door body bottle holder 21 directly faces the user, making access more convenient and safer and more worry-free.

[0042] As Figure 1 , Figure 2 shown, the number of connecting mechanisms 30 is configured to be two sets, and the two sets of connecting mechanisms 30 are arranged symmetrically on the upper and lower sides of the box body 10 along the height direction of the refrigerator 100. That is to say, the box body 10 can use two sets of connecting mechanisms 30 to carry the door body 20, so as to improve the stability of the door body 20 during the opening and closing process. It can be understood that in other embodiments, the number of connecting mechanisms 30 can also be configured to be one set, three sets, four sets, or even more sets, which will not be elaborated here.

[0043] As Figure 1 , Figure 2 shown, the length of the guide rail seat 311 is less than half of the width of the box body 10, which creates conditions for seamless cooperation between the two door bodies 20 and the box body 10 after closing. Here, the length of the guide rail seat 311 can be slightly less than half of the width of the box body 10, and the telescopic rod 312 can retract into the guide rail seat 311, and the free end 3121 is received within the area where the guide rail seat 311 is located.

[0044] In this application, a door seal (not shown in the figure) is provided on the door body 20, and a concave cavity is formed on the door seal, and the concave cavity is matched with the guide rail assembly 31; when the door body 20 closes the box body 10, the concave cavity can receive the guide rail assembly 31, and the box body 10 and the door body 20 can be sealed by the door seal. That is to say, the door body 20 is assembled and sealed with the box body 10 through the door seal, and the sealing between the door body 20 and the box body 10 by the door seal will not be affected by the existence of the guide rail assembly 31. It should be noted that the specific structure of the door seal and how to achieve the sealing between the door body 20 and the box body 10 in the closed state can adopt existing conventional methods, which will not be elaborated here.

[0045] As Figure 3As shown, the first hinge piece 321 is abutted against the free end 3121, and the first hinge piece 321 and the free end 3121 are fixedly connected by a bolt-nut assembly (not shown in the figure). This facilitates the assembly connection between the first hinge piece 321 and the free end 3121 on the telescopic rod 312. Since the first hinge piece 321 is abutted against the free end 3121, the contact area between the two is large, ensuring the stability of the connection between the first hinge piece 321 and the free end 3121. It can be understood that in other embodiments, the first hinge piece 321 and the free end 3121 can also be fixedly connected by welding.

[0046] As Figure 3 shown, the second hinge piece 322 is abutted against the door body 20, and the second hinge piece 322 and the door body 20 are fixedly connected by a fixing member (not shown in the figure). Here, the fixing member can pass through the second hinge piece 322 and then be threadedly connected to the door body 20, facilitating the assembly connection between the second hinge piece 322 and the door body 20. Moreover, since the second hinge piece 322 is abutted against the door body 20, the contact area between the two is large, ensuring the stability of the connection between the second hinge piece 322 and the door body 20. Here, the fixing member can specifically be a bolt, a screw, etc.

[0047] In this application, the rotation angle between the first hinge piece 321 and the second hinge piece 322 is set to P, and 180° ≥ P ≥ 0°; wherein, when the rotation angle between the first hinge piece 321 and the second hinge piece 322 is 0°, the door body 20 can close the box body 10. That is to say, the maximum opening angle of the door body 20 is 180°, ensuring the operation space and vision for users when accessing items. It should be noted that the conventional existing method can be used to realize the rotational connection between the first hinge piece 321 and the second hinge piece 322, and no further elaboration will be made here.

[0048] In summary, when the user opens the door body 20, by applying force to the door body 20 with the hand and utilizing the structural characteristics of the guide rail assembly 31 and the door hinge 32, the door body 20 can be simultaneously driven to slide and rotate to fully open the door body 20 outside the box body 10.

[0049] 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.

[0050] Those of ordinary skill in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. As long as appropriate changes and variations made to the above embodiments fall within the scope of the spirit of the present utility model, they are within the scope of protection required by the present utility model.
