[0037] During the refrigerator production process, refrigerators are prone to tipping over when the production line shakes or is started / stopped. If employees are not careful while operating the production line, the refrigerator may tip over and injure them, causing work-related injuries. Damage to parts after a refrigerator tipps over can also cause property damage.
[0038] The main purpose of this utility model is to propose a refrigerator that, during the online transfer process in the production process, aims to at least solve the problem in related technologies where refrigerators are prone to tipping over during the online transfer process.
[0039] Please see Figure 1 , Figure 2 and Figure 3In one embodiment of this utility model, the refrigerator 100 includes a cabinet 1, a rear anti-tipping member 2, at least one cabinet door 3, and a front anti-tipping member 4. The cabinet 1 has a receiving cavity with a front opening, and the receiving cavity includes at least one compartment. At least one rear anti-tipping member 2 is provided and is disposed adjacent to the rear side of the cabinet 1. The rear anti-tipping member 2 includes a rear support portion 21 that protrudes at least partially from the bottom of the cabinet 1. The at least one cabinet door 3 is provided to cover the opening end of the receiving cavity. One side end of the cabinet door 3 is rotatably mounted to the cabinet 1 so that the compartment can be opened and closed during the rotation stroke. The cabinet door 3 is at least able to cover the lower edge of the opening. At least one front anti-tipping member 4 is provided and is disposed adjacent to the front side of the cabinet 1. The front anti-tipping member 4 includes a front support portion 41 that protrudes at least partially from the bottom of the cabinet door 3.
[0040] In the technical solution of this utility model, the refrigerator 100 includes a cabinet 1, a rear anti-tipping member 2, at least one door 3, and a front anti-tipping member 4. The rear anti-tipping member 2 is disposed adjacent to the rear side of the cabinet 1, and includes a rear support portion 21 that protrudes at least partially from the bottom of the cabinet 1. The front anti-tipping member 4 is disposed adjacent to the front side of the cabinet 1, and includes a front support portion 41 that protrudes at least partially from the bottom of the door 3. With this configuration, during the production process, if the refrigerator 100... When the refrigerator 100 tilts on the production line, the cabinet 1 rotates, and the front support 41 and the rear support 21 rotate with the cabinet 1. Since the front support 41 protrudes at least partially from the bottom of the door 3 and the rear support 21 protrudes at least partially from the bottom of the cabinet 1, when the cabinet 1 tilts forward or backward, the front support 41 or the rear support 21 can quickly come into contact with the production line to support the cabinet 1 and prevent the refrigerator 100 from continuing to tilt.
[0041] During the start-up and shutdown of the production line, the refrigerator 100 tends to maintain its original state, that is, the refrigerator 100 may tip over due to inertia. Therefore, when transporting the refrigerator 100 through the production line, the front-back direction of the refrigerator 100 should be kept consistent with the transport direction of the production line.
[0042] The rear anti-tipping component 2 can be located at the bottom of the box 1 near the rear side, or it can be located on the side of the box 1 near the rear side, or it can be directly located on the rear side of the box 1.
[0043] The rear support portion 21 may partially protrude from the bottom of the housing 1. For example, when the rear support portion 21 is located on the side of the housing 1, the rear support portion 21 may protrude entirely from the bottom of the housing 1.
[0044] In a further embodiment, the rear end of the rear support 21 protrudes beyond the rear side of the cabinet 1. It is understood that when the refrigerator 100 tilts backward, it typically rotates forward around the rear end of its bottom. When the rear end of the rear support 21 protrudes beyond the rear side of the cabinet 1, the rear end of the rear support 21 is further away from the center of rotation. While the angular velocity of the rear support 21 is the same at all points as the cabinet 1 rotates, the linear velocity at the rear end of the rear support 21 is faster. This means the rear end of the rear support 21 can quickly support itself on the production line, preventing the center of gravity from becoming too low and exceeding the limit of the rear support 21 after the cabinet 1 rotates too much. It also provides a larger support area, improving the stability of the support.
[0045] As can be seen from the above, the greater the protrusion of the rear support portion 21, the faster the rear support portion 21 supports the cabinet 1, the larger the support area, and thus the stronger the anti-tipping ability. However, a greater protrusion of the rear support portion 21 also results in a larger overall footprint of the refrigerator 100, which may lead to incompatibility issues on different production lines. Therefore, in this embodiment of the present invention, the rear support portion 21 is movably configured relative to the cabinet 1 to adjust its protrusion size; thus, the protrusion size can be adjusted according to the actual production situation.
[0046] In addition, when the user actually installs the refrigerator 100, the distance between the rear side of the cabinet 1 and the wall or cabinet is reduced. If the protruding size of the rear support 21 is too large, it may affect the user's installation. By making the protruding size of the rear support 21 adjustable, the protruding size can be increased during production to obtain better anti-tipping capability; during actual installation, the protruding size can be set to be smaller, or even zero, to facilitate user installation.
[0047] The rear anti-tipping component 2 can be provided as one, two, or more. When one is provided, the rear anti-tipping component 2 should be positioned as close to the center as possible to ensure the force balance when the rear support part 21 supports the box body 1. (See attached...) Figure 1 As shown, when two rear anti-tipping components 2 are provided, they should be placed as close as possible to the left and right ends for more stable and reliable support.
[0048] In the embodiments of this utility model, please refer to Figure 2 The rear anti-tipping component 2 further includes a fixing part 22 and a locking structure 23. The fixing part 22 is disposed at the bottom of the housing 1 and has a sliding groove 221 extending in the front-rear direction. The locking structure 23 includes a locking part 231 and a locking engagement part 232 respectively disposed on the fixing part 22 and the rear support part 21. The locking part 231 and the locking engagement part 232 can cooperate to lock the rear support part 21 and the fixing part 22. At least one of the locking part 231 and the locking engagement part 232 is provided in multiple ways in the front-rear direction. The rear support part 21 is slidably disposed in the sliding groove 221 in the front-rear direction.
[0049] In this embodiment, the rear support 21 is slidably disposed in the slide groove 221. The locking part 231 and the locking engagement part 232 keep the rear support 21 fixed to the box body 1, so as to prevent the rear support 21 from sliding relative to the box body 1 after contacting the ground when the box body 1 is tilted, thus preventing it from failing to provide normal support. Since at least one of the locking part 231 and the locking engagement part 232 is arranged in multiples along the front-back direction, when it is necessary to adjust the protrusion size of the rear support 21, the rear support 21 can be slid in the slide groove 221. After adjustment, the rear support 21 can be fixed by the cooperation of the locking part 231 and the locking engagement part 232 at the corresponding positions.
[0050] The adjustment method for the protruding size of the rear support portion 21 is not limited to sliding. In some embodiments, the rear support portion 21 can be rotatably disposed at the bottom of the housing 1 along an axis extending vertically, so that the size of the protruding front end of the rear support portion 21 is adjustable during its rotational stroke. In some embodiments, the rear support portion 21 itself can be folded.
[0051] The locking part 231 and the locking engagement part 232 can take various forms. In some embodiments, the locking part 231 and the locking engagement part 232 can be configured as a slot and a block. One of the slots and blocks is provided with multiple slots and blocks along the front-back direction. Thus, the rear support part 21 can be fixed in different positions in the slide groove 221 by engaging at different positions, thereby completing the adjustment of the protrusion size.
[0052] In this embodiment, the rear support portion 21 is provided with a plurality of locking holes arranged in the front-to-back direction. A fastening knob is threaded onto the fixing portion 22. One end of the fastening knob near the rear support portion 21 can extend into the locking hole located in the slide groove 221. One of the locking hole and the fastening knob constitutes the locking portion 231, and the other constitutes the locking engagement portion 232. When adjustment is required, the fastening knob is rotated so that its end disengages from the locking hole, allowing the rear support portion 21 to slide freely back and forth along the slide groove 221. After sliding to a suitable position, the fastening knob is rotated again so that its end extends into the corresponding locking hole, thus fixing the rear support portion 21 and completing the adjustment of the protrusion size.
[0053] As can be seen from the above, during actual installation, the rear side of the cabinet 1 is basically set against the wall, meaning that the refrigerator 100 will not tip backward. Therefore, in this utility model, the rear support part 21 is detachably connected to the cabinet 1. The refrigerator 100 can be removed from the cabinet 1 after leaving the factory or before user installation. During production, the rear support part 21 can be reused, saving production costs.
[0054] As mentioned above, there are multiple ways to adjust the protrusion size of the rear support 21. Corresponding to the detachable connection between the rear support 21 and the housing 1, in some embodiments, the bottom of the housing 1 has multiple mounting positions arranged in the front-to-back direction. The rear support 21 can be installed in multiple mounting positions to adjust its protrusion size. That is, during the production process, the rear support 21 can be installed in the mounting position with a larger protrusion size by installation and disassembly. During the user installation process, the rear support 21 can be installed in the mounting position with a smaller or zero protrusion size.
[0055] In this embodiment, corresponding to the sliding arrangement of the rear support 21, in order to disassemble the rear support 21, the slide groove 221 is at least open at its rear end, and the rear support 21 can slide out from the opening of the slide groove 221. That is, after the refrigerator 100 leaves the factory or before the user installs it, the rear support 21 can be taken out from the slide groove 221 for recycling. During production, the rear support 21 can be reused, saving production costs.
[0056] Of course, it's possible that some users, when installing the refrigerator 100, consider their home's spatial layout, resulting in a greater distance between the refrigerator 100 and the wall. In such cases, the rear support 21 can be retained. Similarly, the connecting part can be detachably connected to the cabinet 1, and can be removed or retained by the user before installation, depending on the actual situation.
[0057] For the fixing part 22, the groove 221 can be formed in various ways. In some embodiments, the groove 221 can be opened on a solid object; in some embodiments, the connecting part is arranged in a square cylindrical shape, and the groove 221 is formed inside it. In this way, it is more convenient to connect the fixing part 22 to the bottom of the box 1, and when the rear support part 21 needs to slide out from the opening of the groove 221, no additional opening is required, as the rear end of the groove 221 itself is already open.
[0058] As can be seen from the above, when the production line suddenly stops due to equipment failure or power outage during the production process, the refrigerator 100 is more likely to tip over in the transport direction. In order to ensure the good anti-tipping function of the rear support 21, the refrigerator 100 is placed on the production line with its rear side facing the transport direction of the production line. However, it is also possible that the refrigerator 100 will tip over in the opposite direction to the transport direction during the startup process.
[0059] Regarding the front anti-tipping component 4, during user operation, the refrigerator 100 typically tilts forward when the door 3 is opened. In this embodiment, by having the front support 41 protrude from the bottom of the door 3, if the refrigerator body 1 tilts when the door 3 is opened, it will rotate forward with the front end of the bottom of the refrigerator body 1 as the fulcrum. The rotation when the door 3 is opened will cause the front support 41 to be positioned in front of the front end of the bottom of the refrigerator body 1. When tilting, the front anti-tipping component 4 will support the refrigerator body 1 at a certain distance in front of the front end of the bottom of the refrigerator body 1, thereby supporting the refrigerator body 1. The support area is relatively large, thus preventing the refrigerator body 1 from continuing to tilt forward and improving the safety performance.
[0060] The number of the box doors 3 can be one or two. In this embodiment, the number of box doors 3 is set to two, and the two box doors 3 rotate in opposite directions. When there are two box doors 3, there are also two front anti-tipping components 4.
[0061] For the refrigerator 100, the bottom of the cabinet 1 is provided with a support leg 5 so that the bottom of the cabinet 1 is suspended to ensure heat dissipation. The bottom of the front support part 41 cannot be lower than the bottom of the support leg 5, otherwise the cabinet door 3 will not be able to be opened. Therefore, the bottom of the front support part 41 is higher than or level with the bottom of the support leg 5.
[0062] The ground is not completely flat. If the bottom of the front support 41 and the bottom of the support leg 5 are flush, in some installation environments, the front support 41 may be in too tight contact with the ground, making it difficult to open the door 3. Therefore, in a preferred embodiment, the refrigerator 100 further includes a support leg 5 disposed at the bottom of the body 1, and the bottom of the front support 41 is higher than the bottom of the support leg 5.
[0063] Please refer to Figure 4 The height difference between the bottom of the front support 41 and the bottom of the support leg 5 is L. It is understood that L should not be too small. If L is too small, in installation environments with uneven ground, the front anti-tipping component 4 may still directly contact the ground. Of course, L should also not be too large. If it is too large, the time required for the front anti-tipping component 4 to support the ground during the forward tilting of the box 11 will be longer, resulting in a larger overall tilt angle of the box 11, which may cause the front support 41 to be insufficient to support the entire box 11. Therefore, in this embodiment of the invention, the height difference between the bottom of the front support 41 and the bottom of the support leg 5 is L, where 7 ≤ L ≤ 10 mm. L can be 7 mm, 9 mm, 10 mm, etc. When L is within this range, during normal use, the front anti-tipping component 4 will not contact the ground, preventing the box door 3 from being difficult to open, and it can also provide timely support for the box 1 when it tilts forward.
[0064] It is understandable that the farther the front support part 41 is located from the rotation axis of the door 3, the farther the front support part 41 will be from the front end of the bottom of the box body 1 when the door 3 is opened. Therefore, in this embodiment, the front support part 41 is located on the side of the door 3 away from its rotational connection with the box body 1, so that the position of the front support part 41 is as far away as possible from the rotation axis when the box body 1 tilts forward. When the door 3 is opened and the box body 1 tilts forward, the front support part 41 and the front end of the bottom of the box body 1 provide a larger support area for the entire box body 1, resulting in more stable support. At the same time, the forward tilting of the box body 1 will also cause the entire door 3 to rotate downward. The farther the position of the front support part 41 is from the front end of the bottom of the box body 1, the faster the front support part 41 will contact the ground to support the box body 1.
[0065] In this embodiment, the refrigerator 100 has a depth range of 435–550 mm; a width range of 830–990 mm; and a height range of 1700–2100 mm. It should be noted that the refrigerator 100 may have only one of these dimensions, or two or all three dimensions together.
[0066] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
