[0002] In modern life, with the diversification of home decoration styles and the continuous changes in house layouts, the placement of household appliances has become more flexible and diverse. Take refrigerators as an example: due to limitations in house size and layout, sometimes one side of the refrigerator needs to be placed against a wall. When the refrigerator door opens at too large an angle, the door is very likely to collide directly with the wall. This not only generates noise but also greatly increases the risk of the door breaking due to impact, affecting the normal use and lifespan of the refrigerator. Although some users choose to install simple cushioning parts such as anti-collision stickers on the door or wall, this solution lacks professionalism and stability, has limited cushioning effect, and may affect the overall aesthetics and ease of use of the refrigerator, failing to fundamentally solve the problem of the door colliding with the wall due to an excessive opening angle. Utility Model Content

[0009] Wherein, the first direction, the second direction, and the third direction are arranged in pairs that intersect each other;

[0010] The stop is located on the sliding stroke of the slider.

[0011] Preferably, the limiting component further includes a slide rail, the slide rail including two side plates protruding from the door body, the two side plates being arranged side by side at intervals in the second direction, and forming a slide groove with open ends between them, the slide groove extending along the third direction;

[0012] The slider is slidably mounted on the groove.

[0013] Preferably, the slide rail further includes a limiting plate, the limiting plate and the stop member are disposed opposite each other in the third direction and are respectively disposed at both ends of the slide rail, the limiting plate is fixedly disposed and seals one end opening of the slide rail;

[0014] In the third direction, the position of the stop member on the slide groove is adjustable to adjust the sliding stroke of the slider within the slide groove.

[0015] Preferably, the stop member is provided with two clearance grooves, each clearance groove corresponding to one of the side plates, so that when the stop member slides along the groove, it avoids the corresponding side plate.

[0016] Preferably, the limiting component further includes an adjustment part disposed on the door body, the adjustment part comprising:

[0017] Adjusting nuts are fixed to the door body; and,

[0018] An adjusting rod is provided along the third direction and passes through the adjusting nut. The outer periphery of the adjusting rod is provided with a threaded section and engages with the internal thread of the adjusting nut so that when the adjusting rod rotates along its central axis, it can move linearly along the third direction.

[0019] One end of the adjusting rod is movably connected to the stop.

[0020] Preferably, the adjusting part further includes two locking nuts sleeved on the outer periphery of the adjusting rod, the internal thread of each locking nut engaging with the threaded section, the two locking nuts being respectively disposed on both sides of the adjusting nut in the third direction, and each locking nut being movable and abutting against the adjusting nut.

[0021] Preferably, the limiting component further includes a limiting member disposed on the door body, the limiting member being disposed corresponding to the other end of the adjusting rod, and being disposed opposite to the stop member in the third direction.

[0028] This utility model provides a limiting component disposed between the main body and the door of a household appliance. The limiting component includes a connecting rod and a stop. The first and second ends of the connecting rod are respectively connected to the main body and the door, with the first end rotatably mounted on the main body and its rotation axis parallel to the pivot axis of the door. When the door rotates relative to the main body, the first end of the connecting rod rotates relative to the main body, and the second end of the connecting rod moves relative to the door. Simultaneously, a stop is provided on the door, positioned along the travel of the second end. When the second end engages with the stop, it cannot continue moving along a predetermined trajectory, preventing the door from rotating further relative to the main body. Furthermore, since the position of the stop on the door is adjustable, it can be positioned at different points to stop and limit the second end, thus adjusting the rotation angle of the door relative to the main body. When the household appliance is placed against a wall, adjusting the door's rotation angle can prevent the door from colliding with the wall when opened. This not only prevents damage to the door due to impact but also improves the user experience. Attached Figure Description

[0045] Household appliances refer to various electrical devices used in homes and similar places. Taking a refrigerator as an example, due to limitations in house size and layout, sometimes it is necessary to place one side of the refrigerator against a wall. To avoid direct collision between the refrigerator door and the wall when it is opened, this utility model improves the structure of the household appliance. The following description of the household appliance will be based on the accompanying drawings.

[0046] Please see Figures 1 to 7 This utility model provides a limiting component 100. The limiting component 100 is used between the main body 200 and the door 300 of the household appliance 1000. The door 300 is pivotally connected to the main body 200, and the pivot axis of the door 300 is set along the first direction F1.

[0047] The limiting assembly 100 includes a connecting rod 1 and a stop 2. The connecting rod 1 has a first end 11 and a second end 12. The first end 11 is rotatably mounted on the main body 200 and its rotation axis is parallel to the pivot axis of the door body 300. The second end 12 is connected to the door body 300 and can move relative to the door body 300 when the door body 300 pivots relative to the main body 200. The stop 2 is disposed on the door body 300 and is disposed corresponding to the second end 12. The stop 2 is located on the active stroke of the second end 12. The position of the stop 2 on the door body 300 is adjustable so as to stop and limit the second end 12 at different positions.

[0048] The limiting component 100 provided by this utility model is disposed between the main body 200 and the door 300 of a household appliance 1000. The limiting component 100 includes a connecting rod 1 and a stop 2. The first end 11 and the second end 12 of the connecting rod 1 are respectively connected to the main body 200 and the door 300, wherein the first end 11 is rotatably mounted on the main body 200, and its rotation axis is parallel to the pivot axis of the door 300. When the door 300 rotates relative to the main body 200, the first end 11 of the connecting rod 1 rotates relative to the main body 200, and the second end 12 of the connecting rod 1 moves relative to the door 300.

[0049] Meanwhile, a stop 2 is provided on the door body 300, and the stop 2 is positioned on the travel of the second end 12. When the second end 12 is engaged with the stop 2, the second end 12 cannot continue to move along the predetermined travel trajectory, and at this time the door body 300 cannot continue to rotate relative to the main body 200.

[0050] Furthermore, since the position of the stop 2 on the door 300 is adjustable, the stop 2 can be positioned at different locations relative to the second end 12 stops, thus making the rotation angle of the door 300 relative to the main body 200 adjustable. When the household appliance 1000 is placed against a wall, the rotation angle of the door 300 can be adjusted to prevent the door 300 from colliding with the wall when it is opened. This not only prevents damage to the door 300 due to impact but also improves the user experience.

[0051] Understandably, the main body 200 typically forms a cavity 201 with an opening 202 on one side in its second direction F2. The door 300 is located on the side of the opening 202 of the main body 200, so that the opening 202 can be opened or closed when the door 300 rotates relative to the main body 200. Taking a refrigerator as an example, the direction in which the height of the refrigerator is located is the first direction F1, the direction in which the thickness of the refrigerator is located is the second direction F2, and the direction in which the width of the refrigerator is located is the third direction F3. The refrigerator main body 200 has a receiving cavity, and in the second direction F2, the receiving cavity has a rear wall and an opening 202 disposed opposite to each other. The refrigerator door is located on the side of the opening 202 of the refrigerator main body 200 and pivots to the refrigerator main body 200, and the refrigerator door can rotate to open or close relative to the refrigerator main body 200.

[0052] In one embodiment, please refer to Figures 1 to 3 The limiting component 100 also includes a slider 3, which is slidably mounted on the door body 300 along a third direction F3. The second end 12 is rotatably mounted on the slider 3, and its rotation axis is parallel to the pivot axis of the door body 300. The stop 2 is located on the sliding stroke of the slider 3.

[0053] In this embodiment, the door 300 is pivotally connected to the main body 200, the slider 3 is slidably mounted on the door 300 along a third direction F3, and the first end 11 of the connecting rod 1 is rotatably mounted on the main body 200, while the second end 12 is connected to the slider 3. That is, the main body 200, door 300, connecting rod 1, and slider 3 form a crank-slider mechanism. The main body 200 corresponds to the frame of the crank-slider mechanism; the door 300 corresponds to the crank of the crank-slider mechanism; and the connecting rod 1 corresponds to the intermediate component connecting the frame and the slider 3.

[0054] When the door 300 pivots relative to the main body 200, the slider 3 can slide along the third direction F3 via the connecting rod 1. The stop 2 is set on the sliding stroke of the slider 3. When the slider 3 and the stop 2 are in a limiting engagement, the door 300 cannot continue to rotate relative to the main body 200.

[0055] Furthermore, since the position of the stop 2 on the door 300 is adjustable, the stop 2 can be stopped and limited by the slider 3 at different positions, thereby making the rotation angle of the door 300 relative to the main body 200 adjustable. When the household appliance 1000 is placed against a wall, the rotation angle of the door 300 can be adjusted to prevent the door 300 from colliding with the wall when it is opened. In this way, not only can the door 300 be prevented from being damaged by impact, but the user experience can also be improved.

[0056] It is understood that in a crank-slider mechanism, slider 3 is a component that can only perform reciprocating linear motion along a fixed guide rail. To ensure the stability of slider 3's motion, in one embodiment, please refer to... Figures 1 to 3 The limiting component 100 also includes a slide rail 4, which includes two side plates 41 protruding from the door body 300. The two side plates 41 are arranged side by side and spaced apart in the second direction F2, forming a groove 42 with open ends between them. The groove 42 extends in the third direction F3. The slider 3 is slidably mounted in the groove 42. By setting the slide rail 4, the slider 3 can make reciprocating linear motion according to a predetermined trajectory, thereby ensuring the stable operation of the crank-slider mechanism.

[0057] Specifically, the slide 4 also includes a limiting plate 43, which is disposed opposite to the stop 2 in the third direction F3 and is located at both ends of the slide groove 42. The limiting plate 43 is fixedly disposed and seals one end opening of the slide groove 42. In the third direction F3, the position of the stop 2 in the slide groove 42 is adjustable to adjust the sliding stroke of the slider 3 in the slide groove 42.

[0058] In other words, by setting a limiting plate 43, one end opening 202 of the slide groove 42 is sealed, thereby preventing the slider 3 from sliding out of the slide groove 42 from the opening. The stop 2 is set corresponding to the other end opening of the slide groove 42. By adjusting the position of the stop 2 on the slide groove 42, the sliding stroke of the slider 3 in the slide groove 42 can be adjusted, thereby making the rotation angle of the door body 300 relative to the main body 200 adjustable.

[0059] The following is combined Figures 4 to 7 Please refer to the explanation. Figure 4 and Figure 5 This is the case where the door 300 rotates 120° relative to the main body 200. The door 300 rotates to a relatively large opening angle relative to the main body 200, and at this time, the sliding stroke of the slider 3 in the slide groove 42 is relatively long. By adjusting the stop 2, the stop 2 is moved towards the opening and disengaged from the opening from the slide groove 42, thereby increasing the sliding stroke of the slider 3 in the slide groove 42.

[0060] Please see Figure 6 and Figure 7 This is the case where the door 300 rotates 100° relative to the main body 200. The opening angle of the door 300 relative to the main body 200 is small, and the sliding stroke of the slider 3 in the slide groove 42 is short. By adjusting the stop 2, moving the stop 2 from the opening towards the middle of the slide groove 42, the sliding stroke of the slider 3 in the slide groove 42 is shortened.

[0061] Thus, by adjusting the position of the stop 2 on the slide groove 42, the slider 3 can be stopped and limited by the stop 2 at different positions, thereby making the rotation angle of the door 300 relative to the main body 200 adjustable.

[0062] Following the previous statement that "when the rotation angle of the door body 300 relative to the main body 200 is small, the sliding stroke of the slider 3 in the slide groove 42 is short," to shorten the sliding stroke of the slider 3 in the slide groove 42, the position of the stop 2 needs to be adjusted towards the middle of the slide groove 42. To make the position adjustment of the stop 2 smoother, in one embodiment, the stop 2 is provided with two clearance grooves 21, each clearance groove 21 corresponding to a side plate 41, so that when the stop 2 slides along the slide groove 42, it avoids the corresponding side plate 41.

[0063] In one embodiment, please refer to Figure 5 , Figure 7 , Figure 8 and Figure 9Two side plates 41 protrude from the door body 300 to form a sliding groove 42. When shortening the sliding stroke of the slider 3 within the sliding groove 42, the stop 2 needs to be moved towards the center of the sliding groove 42. To facilitate the adjustment of the stop 2's position, a clearance groove 21 is provided on the stop 2 to avoid the corresponding side plate 41 when the stop 2 slides along the sliding groove 42. At this time, a portion of the stop 2 is accommodated within the sliding groove 42, and the stop 2 is essentially slidably installed within the sliding groove 42.

[0064] This application does not impose specific limitations on the method of adjusting the position of the stop member 2. In one embodiment, the position of the stop member 2 can be adjusted by means of a locking structure using an elongated hole and a bolt. In another embodiment, the position of the stop member 2 can be adjusted by providing a movable adjusting part 5, which drives the stop member 2.

[0065] Specifically, please refer to Figure 8 and Figure 9 The limiting assembly 100 also includes an adjusting part 5 disposed on the door body 300. The adjusting part 5 includes an adjusting nut 51 and an adjusting rod 52. The adjusting nut 51 is fixed to the door body 300; the adjusting rod 52 is disposed along a third direction F3 and passes through the adjusting nut 51. The outer periphery of the adjusting rod 52 is provided with a threaded section and engages with the internal thread of the adjusting nut 51 so that when the adjusting rod 52 rotates along its central axis, it can move linearly along the third direction F3; wherein, one end of the adjusting rod 52 is movably connected to the stop member 2.

[0066] In other words, during the adjustment process, rotating the adjusting rod 52 allows it to move linearly along the third direction F3 because the outer circumference of the adjusting rod 52 has a threaded section that engages with the internal thread of the adjusting nut 51. One end of the adjusting rod 52 is movably connected to the stop 2, so when the adjusting rod 52 rotates, it can drive the stop 2 to move linearly along the third direction F3. Thus, the stop 2 can move towards the center of the slide groove 42, or towards the opening of the slide groove 42, thereby adjusting the sliding stroke of the slider 3 within the slide groove 42.

[0067] After the stop 2 is adjusted, in order to prevent the stop 2 from shifting, in one embodiment, the adjusting part 5 further includes two locking nuts 53 sleeved on the outer periphery of the adjusting rod 52. The internal thread of each locking nut 53 engages with the threaded section, and the two locking nuts 53 are respectively located on both sides of the adjusting nut 51 in the third direction F3. Each locking nut 53 can be moved to abut against the adjusting nut 51.

[0068] In this embodiment, when the position of the stop 2 needs to be adjusted, the two locking nuts 53 are first loosened so that both locking nuts 53 are separated from the adjusting nut 51. At this time, there is sufficient adjustment space between the adjusting nut 51 and the two locking nuts 53. By rotating the adjusting rod 52, the adjusting rod 52 moves in the third direction F3. When the adjusting rod 52 drives the stop 2 to the target position, the two locking nuts 53 are tightened respectively. Each locking nut 53 moves to abut against the adjusting nut 51, thereby achieving the positioning of the adjusting rod 52.

[0069] It is understandable that even without limiting the door 300, the door 300 of the household appliance 1000 has a maximum rotation angle relative to the main body 200. Taking a maximum rotation angle of 120° relative to the main body 200 as an example, the sliding stroke of the slider 3 within the slide groove 42 reaches its maximum. Therefore, the stop 2 needs to be moved towards the opening of the slide groove 42 and disengaged from the opening. To prevent the stop 2 from malfunctioning due to over-adjustment, the maximum adjustment position of the stop 2 needs to be limited.

[0070] In one embodiment, please refer to Figure 5 The limiting component 100 also includes a limiting member 6 disposed on the door body 300. The limiting member 6 is disposed at the other end of the adjusting rod 52 and is disposed opposite to the stop member 2 on the third direction F3. For example, when the maximum rotation angle of the door body 300 relative to the main body 200 is set to 120°, the sliding stroke of the slider 3 in the slide groove 42 reaches its maximum. At this time, it is necessary to move the stop member 2 toward the opening of the slide groove 42 and make the stop member 2 disengage from the opening of the slide groove 42.

[0071] To ensure that the slider 3 can engage with the stop 2 when the door 300 rotates 120° relative to the main body 200, a limiting member 6 is required to limit the maximum adjustment position of the stop 2. That is, by adjusting the adjusting rod 52 so that its other end abuts against the limiting member 6, the adjusting rod 52 causes the stop 2 to disengage from the opening into the slide groove 42. When the door 300 rotates relative to the main body 200 and the slider 3 engages with the stop 2, the door 300 rotates to its maximum rotation angle of 120° relative to the main body 200.

[0072] As described above, when the door 300 rotates open, the slider 3 and the stop 2 limit the rotation angle of the door 300. In actual use, when the user opens the door, when the door 300 rotates to the limited angle, the slider 3 will contact the stop 2, thus preventing the door 300 from continuing to rotate open. To avoid vibration caused by the collision between the slider 3 and the stop 2, in one embodiment, the stop 2 is at least flexibly configured on its side facing the second end 12. Thus, when the slider 3 collides with the stop 2, the locally flexible position of the stop 2 can absorb and buffer the impact force, thereby reducing vibration.

[0073] This utility model also provides a household appliance 1000. Please refer to [link / reference]. Figure 1 and Figure 2 The household appliance 1000 includes a main body 200, a door 300, and a limiting component 100. The main body 200 forms a cavity 201 with an opening 202 on one side in the second direction F2. The door 300 is pivotally connected to the main body 200 and located on the side of the opening 202 of the main body 200. The door 300 can rotate relative to the main body 200 to open or close the opening 202. The limiting component 100 is disposed between the main body 200 and the door 300 to limit the opening angle of the door 300 relative to the main body 200.

[0074] It should be noted that the limiting component 100 is configured as the aforementioned limiting component 100, which includes all the technical features of the aforementioned limiting component 100. Therefore, the household appliance 1000 also includes all the technical features of the aforementioned limiting component 100, and thus has the technical effects brought about by all the aforementioned technical features.
