[0030] This application provides a refrigerator door to solve the problem of cold air leakage from refrigerator doors. The following description will be provided in conjunction with the accompanying drawings.
[0031] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, this type of cabinet door includes:
[0032] Door 1, used to be movably connected to the refrigerator body;
[0033] Handle 2, located on the outside of door body 1 and movably connected to door body 1; and,
[0034] The door lock 3 includes a base 31 movably connected to the inside of the door body 1, and a plurality of locking parts 32 connected to the base 31;
[0035] The base 31 is movably connected to the handle 2. The handle 2 drives the door lock 3 to move so that the locking part 32 is locked with the box or unlocked from the box.
[0036] It should be noted that "movable connection" and "movable connection" refer to connection methods that allow for positional changes, such as sliding and rotating. The movable connection methods used by the door body 1, handle 2, and door lock 3 can be the same or different. The locking part 32 refers to the structure that uses a detachable connection method to fix the door body 1 to the refrigerator body, such as a buckle or magnetic attraction.
[0037] Understandably, by providing multiple locking parts 32 on the door 1 to connect with the cabinet, the locking force can be more evenly distributed on the cabinet when the locking parts 32 are locked with it, reducing the gap between the door seal on the door and the cabinet, thus solving the problem of refrigerator leakage caused by poor sealing. Simultaneously, utilizing the movable connection between the base 31 and the door lock 3, pulling the handle 2 can drive multiple locking parts 32 to move synchronously, simultaneously locking or unlocking them with the cabinet. This quick and efficient process facilitates easy opening and closing of the cabinet door for the user.
[0038] The aforementioned door seal refers to a structure made of a material that combines flexibility and magnetism. When the distance between the door and the cabinet is reduced, the door seal can automatically attract the cabinet under the magnetic attraction of the cabinet.
[0039] In some embodiments, such as Figure 1 and Figure 2 As shown, one end of the handle 2 is rotatably connected to the door body 1, and the seat 31 is slidably connected to the door body 1. The seat 31 is provided with a connecting part 311 that is movably connected to the handle 2. The handle 2 rotates to drive the door lock 3 to slide so that the locking part 32 is locked with the box or unlocked from the box.
[0040] It should be noted that one end of the handle 2 is rotatably connected to the door body 1, while the other end of the handle 2 is used for the user to hold and drive the handle 2 to rotate.
[0041] It is understood that, through the connecting part 311 movably connected to the handle 2, the rotational driving force of the handle 2 can be converted into a force that drives the door lock 3 to slide, so that multiple locking parts 32 slide synchronously with the seat 31. For example, the handle 2 and the connecting part 311 can be connected by a rotational connection, a sliding connection, or other methods.
[0042] In some embodiments, such as Figure 2 As shown, the handle 2 includes a handle part 21 and a handle seat 22 connected to each other. The handle part 21 is located on the outside of the door body 1. One end of the handle seat 22 is rotatably connected to the door body 1. The handle seat 22 is provided with a slide groove 221. The connecting part 311 is slidably connected in the slide groove 221. The extension direction of the slide groove 221 is inclined to the sliding direction of the door lock 3.
[0043] It should be noted that the outer side of door 1 refers to the side of door 1 that faces away from the housing, and the corresponding inner side of door 1 is the outer side of door 1. The handle 21 located on the outer side of door 1 is for the user to grip. The extension direction of the slide groove 221 is inclined to the sliding direction of the door lock 3, meaning that the angle between the extension direction of the slide groove 221 and the sliding direction of the door lock 3 is neither equal to 0 degrees nor equal to 180 degrees.
[0044] It is understood that the sliding connection between the door lock 3 and the handle 2 is achieved by using the slide groove 221 and the connecting part 311. The inclined direction of the slide groove 221 can convert the rotation of the handle 2 into the sliding of the door lock 3. For example, the extension direction of the slide groove 221 can be a straight line or a curve, and correspondingly the sliding path of the door lock 3 can be a straight line or a curve, as long as it can achieve the locking or unlocking of the locking part 32 and the housing.
[0045] In some embodiments, such as Figure 2 As shown, the sliding direction of the door lock 3 is perpendicular to the rotation axis of the handle seat 22, and the connecting part 311 is embedded in the slide groove 221 along the rotation axis direction of the handle seat 22.
[0046] Understandably, the connecting part 311 connects the handle seat 22 to the seat body 31. The connecting part 311 is embedded in the slide groove 221 along the rotation axis of the handle seat 22, which can prevent the connecting part 311 from coming out of the slide groove 221 during the movement of the handle 2. The sliding direction of the door lock 3 is perpendicular to the rotation axis of the handle seat 22, which can achieve efficient transmission.
[0047] In some embodiments, such as Figure 3 and Figure 4 As shown, the groove 221 extends in a direction away from the handle portion 21.
[0048] It is understandable that when the handle 21 is pulled outward, the displacement of the groove wall of the slide 221 can cause the door lock 3 to slide in the direction close to the handle seat 22, or in the direction away from the handle seat 22.
[0049] For example, the slide 221 extends in a direction away from the pivot of the handle 21 and the handle seat 22. It can be imagined that such a slide 221 is inclined upwards. When the door is closed, if the connecting part 311 is located at the lower end of the slide 221, when the handle 21 is pulled outwards, the wall of the slide 221 drives the door lock 3 to slide upwards to release the locking part 32 from the door's lock. After the ice is removed, the handle 21 is released, and the door lock 3, under gravity, drives the handle seat 22 to rotate inwards until the locking part 32 locks with the door, thus automatically closing the door.
[0050] In some embodiments, such as Figure 2 As shown, the locking part 32 protrudes from the seat 31, and the end of the locking part 32 away from the seat 31 is bent along the direction in which the locking part 32 engages with the housing.
[0051] It should be noted that the bending of the end of the locking part 32 away from the base 31 along the direction in which the locking part 32 engages with the box body means that the locking part 32 has a hook-like structure, and the locking part 32 and the box body are locked by a snap-fit connection. Correspondingly, the box body is provided with a slot for the locking part 32 to engage. When the box door is opened, the locking part 32 deforms and disengages from the slot, thereby releasing the locking state between the box door and the box body.
[0052] Specifically, two locking parts 32 are provided at intervals along the sliding direction of the door lock 3.
[0053] In some embodiments, such as Figure 3 and Figure 4 As shown, the seat 31 and the locking part 32 are both located above the slide groove 221. The slide groove 221 is located above the pivot of the handle seat 22. The end of the slide groove 221 away from the handle part 21 extends in a direction away from the pivot of the handle seat 22.
[0054] It should be noted that the slide 221 in this embodiment can be imagined to extend upward at an angle.
[0055] Understandably, when the door is closed, if the connecting part 311 is located at the lower end of the slide groove 221, when the handle part 21 is pulled outward, the groove wall of the slide groove 221 drives the door lock 3 to slide upward to release the locking part 32 from the door. After the ice is removed, the handle part 21 is released, and the door lock 3 drives the handle seat 22 to rotate inward under the action of gravity until the locking part 32 locks with the box body, thus realizing the automatic closing of the door.
[0056] In some other embodiments, the connecting portion 311 and the handle seat 22 are both located among a plurality of locking portions 32, and the distance between the locking portion 32 near the handle seat 22 and the handle seat 22 is greater than the maximum sliding distance of the locking portion 32. In this way, the handle seat 22 can be prevented from interfering with the sliding of the door lock 3.
[0057] In some embodiments, such as Figure 2 and Figure 3 As shown, the inner side of the door body 1 is provided with a slide rail 11 extending in the vertical direction, and the seat body 31 is slidably connected to the slide rail 11.
[0058] It is understandable that the slide rail 11 is used to restrict the door lock 3 from sliding in a straight line, so as to constrain the movement of the door lock 3 and ensure that the locking part 32 can be smoothly engaged in the slot of the box.
[0059] In some embodiments, such as Figure 3 and Figure 4 As shown, the two ends of the slide 11 are respectively set as an open end and a sealed end, and the direction of the sealed end pointing to the open end is the same as the direction of the locking part 32 locking with the box.
[0060] Understandably, the open end can prevent interference with the sliding of the seat 31, which would cause the locking part 32 to lock with the housing.
[0061] This application also provides a refrigerator, including a cabinet and a door as described above. The specific structure of the door is as described in the above embodiments. Since this refrigerator adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The door 1 is movably connected to the cabinet.
[0062] In some embodiments, the housing is provided with multiple slots, and each slot corresponds to a locking part 32.
[0063] In the above embodiments, the descriptions of each embodiment have different focuses. Parts not described in detail in a particular embodiment can be referred to in the relevant descriptions of other embodiments. In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more features.
