Description

Technical Field

[0001] This disclosure relates to the field of household appliance technology, and more specifically to a household appliance. Background Technology

[0002] Household appliances typically have door stops to limit the maximum opening angle and prevent the door from opening too wide and colliding with other furniture or walls, causing damage. However, the vast majority of existing household appliances can only control the opening angle to a single maximum.

[0003] Taking refrigerators as an example, the maximum opening angle of most mainstream products on the market is over 100°. However, different families have different preferences for the placement of refrigerators. Some families choose to place the refrigerator against one side of a wall or cabinet, some families place it against both sides of a wall or cabinet, and some families have the refrigerator against neither side of a wall.

[0004] If the refrigerator is placed against a wall or in a cabinet, a large maximum opening angle can cause the door to hit the wall or cabinet wall when fully opened, resulting in damage to the door and its appearance. Therefore, users who choose to place their refrigerator against a wall or in a cabinet generally prefer a maximum opening angle of around 90 degrees without hitting the wall or cabinet. For refrigerators placed without either side against a wall, users would ideally prefer a maximum opening angle that is as large as possible for easier access to food.

[0005] The existing refrigerator design, which limits the maximum opening angle of the door, obviously cannot meet the diverse needs of different users. Utility Model Content

[0006] One object of the present disclosure is to provide an improved household appliance.

[0007] Therefore, this disclosure provides a household appliance including a housing and a door, the housing defining at least one chamber, the door being movably connected to the front of the housing via a hinge to open or close at least a portion of the chamber, and further comprising: a stop member including opposing first and second sides; a first stop edge located on the first side, the first stop edge being used to limit the maximum opening angle of the door to a first angle; and a second stop edge located on the second side, the second stop edge being used to limit the maximum opening angle of the door to a second angle, the second angle being not equal to the first angle; wherein the stop member is rotatably mounted to the door such that one of the first stop edge and the second stop edge together provides a stopping action, while simultaneously disabling the stopping action of the other of the first stop edge and the second stop edge.

[0008] This implementation scheme integrates two stop edges onto a single stop component, allowing the door to be selectively stopped at two maximum opening angles, better meeting users' personalized needs. Based on the specific placement of household appliances within the home, the required maximum opening angle of the door is determined, thus determining the installation direction of the stop component on the door, ensuring that the stop edge corresponding to the required maximum opening angle effectively functions as a stop. This satisfies the personalized needs of different users.

[0009] Furthermore, different maximum door opening angles can be switched simply by flipping the stop. The operation is simple, facilitating installation by workers in the user's home and shortening installation time. Even users can easily switch the maximum door opening angle themselves.

[0010] Optionally, in response to the stop member being installed on the door with its first side facing the door, the second stop edge functions as a stop; in response to the stop member being installed on the door with its second side facing the door, the first stop edge functions as a stop. By activating the corresponding stop edge through the installation method, stoppage at different angles can be achieved.

[0011] Optionally, the hinge includes a hinge axis, and the stop has an arc-shaped edge, the center of which falls on the axis of the hinge axis. One end of the projection of the first stop and the second stop along the direction from the second side to the first side is located on the arc-shaped edge. The end of the arc-shaped edge where the projection of the first stop along the direction from the second side to the first side is located is denoted as the first end, and the end of the arc-shaped edge where the projection of the second stop along the direction from the second side to the first side is located is denoted as the second end. During door opening, the first end and the second end rotate with equal radii. Furthermore, the first end and the second end are located at opposite ends of the arc-shaped edge along its extension direction. The arc length of the first end rotating about its axis during the door opening from the closed position to a first angle is different from the arc length of the second end rotating about its axis during the door opening from the closed position to a second angle, thereby achieving limiting of different maximum opening angles.

[0012] Optionally, the first stop and the second stop have a height difference along the height direction of the household appliance. The first stop and the second stop are staggered in height to ensure that when one stop is in a stopping function, it will not be interfered with by the other stop.

[0013] Optionally, in the first and second stop edges, the first or second stop edge that acts as a stop protrudes from the door, while the first or second stop edge that fails to stop protrudes from the door. The stop edge that does not stop is flush with or recessed into the door to avoid interference with the hinges when the door is opened, thus preventing it from affecting the actual maximum opening angle of the door.

[0014] Optionally, during the opening of the door from the closed position to the corresponding maximum opening angle, the area covered by the first stop edge during its movement at least partially overlaps with the area covered by the second stop edge during its movement. The difference in the areas covered by the two stop edges during their movement achieves a stopping effect at different maximum opening angles.

[0015] Optionally, the first angle is greater than the second angle, and the area covered by the first stop during movement is greater than the area covered by the second stop during movement. The larger the area covered by the stop during movement, the greater the angle at which the door can open, that is, the greater the maximum opening angle.

[0016] Optionally, the hinge includes a stop portion for cooperating with the stop member. The first angle is greater than the second angle. During the opening of the door from the closed position to the first angle, along the direction from the second side to the first side, the projection of the second stop edge reaches the stop portion before the projection of the first stop edge. When the second stop edge acts as a stop, since the second stop edge reaches the stop portion before the first stop edge, the door is restricted from further opening when it is opened to the second angle due to the cooperation between the second stop edge and the stop portion. At this time, the door cannot continue to open to allow the first stop edge to reach the stop portion. When the first stop edge acts as a stop, the projection of the second stop edge reaches the stop portion first, but since the stopping function of the second stop edge is ineffective, the door can continue to open at the second angle until the first stop edge and the stop portion cooperate to restrict the door at the first angle.

[0017] Optionally, the door includes a lower edge clip defining the lower boundary of the door, the lower edge clip being provided with a mounting groove recessed toward the inside of the door, the mounting groove being for receiving the stop member.

[0018] Optionally, the stop member has an axisymmetric structure. For household appliances with multiple doors, such as French door refrigerators, the stop member can be interchangeable on both the left and right doors. Making the stop member a universal, standard part improves compatibility.

[0019] Optionally, the first angle is greater than the second angle, wherein, in response to the stop member being installed in the mounting groove with its second side facing the door, the stop member fills the mounting groove; in response to the stop member being installed in the mounting groove with its first side facing the door, there is a non-zero gap between the stop member and the mounting groove. Thus, regardless of whether the stop member's actual stopping edge is the first or second stopping edge, the mounting groove can reliably receive the stop member, ensuring reliable door limiting.

[0020] Optionally, the stop member includes: a mounting portion; a first protrusion extending from the mounting portion toward a first side, wherein the first stop edge is formed on the first protrusion; a second protrusion extending from the mounting portion toward a second side; and a protruding edge extending from the second protrusion toward a direction away from the mounting portion, wherein the second stop edge is formed on the protruding edge. Thus, the first stop edge and the second stop edge are offset from each other in the direction from the first side to the second side, ensuring that when the stop member is installed on the door, only one of the two stop edges always provides effective stopping.

[0021] Optionally, the surface of the protruding edge facing the first side is provided with a first mark, which indicates the first angle; and / or, the surface of the protruding edge facing the second side is provided with a second mark, which indicates the second angle. Thus, the mark of the maximum opening angle and the corresponding stop are indicated on the same side, facilitating the identification of the correct assembly posture during installation.

Detailed Implementation

[0034] To make the above-mentioned objects, features and advantages of this disclosure more apparent and understandable, specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings.

[0035] Figure 1 This is a schematic diagram of a household appliance 1 according to an embodiment of the present disclosure.

[0036] Household appliances 1 can include refrigeration appliances, dishwashers, steam ovens, ovens, etc. Refrigeration appliances can be, for example, refrigerators, freezers, wine cabinets, car refrigerators, etc. Figure 1 The French door refrigerator is used as an example for demonstration. In practical applications, the design of the stop 2 in this implementation scheme can also be applied to various types of refrigerators such as cross door refrigerators, side door refrigerators, multi-door refrigerators, and single door refrigerators.

[0037] For ease of description, in this embodiment, the width direction of the household appliance 1 is denoted as the x-direction, the depth direction as the y-direction, and the height direction as the z-direction. In this embodiment, the front and back directions refer to the y-direction and its opposite. Specifically, "front" or "front side" refers to the direction in which the household appliance 1 faces the user when in use, "rear" or "rear side" refers to the direction in which the household appliance 1 is away from the user when in use, "above" or "upper side" refers to the z-direction as shown in the diagram, and "below" or "lower side" refers to the opposite direction of the z-direction as shown in the diagram. When the door 11 is in the closed position, the thickness direction of the door 11 is in the same direction as the y-direction, and the width direction of the door 11 is in the same direction as the x-direction.

[0038] Specifically, refer to Figure 1The household appliance 1 includes a housing 10 and a door 11. The housing 10 defines at least one chamber. In the example where the household appliance 1 is a refrigerator, the chamber may specifically be a storage compartment. The storage compartment may be, for example, a freezer compartment, a refrigerator compartment, a variable temperature compartment, or a zero-degree compartment. The door 11 is movably connected to the front of the housing 10 to open or close at least a portion of the chamber. Figure 1 The exemplary French door refrigerator shown includes three storage compartments. Figure 1 The two doors 11 at the top are used to jointly close and open the storage room, which is a cold storage room with a temperature range of, for example, 2°C to 8°C. Figure 1 The door 11 located in the middle along the z-direction is a storage room that can be closed and opened and is a variable temperature room. Figure 1 The lower center door 11 is used to close or open the storage compartment, which is a freezer compartment with a temperature, for example, between minus ten and minus twenty degrees Celsius.

[0039] Door 11 is rotatably connected to housing 10 via hinge 13. For example, hinge 13 is fixed to housing 10. Figure 1 The two doors 11 at the top are connected to the housing 10 via hinges 13. Doors 11 can also be drawer-type doors, which can move relative to the housing 10 in the y-direction or its opposite direction to be pulled out or pushed back into the housing 10. For example, Figure 1 The middle and lower doors 11 shown are both drawer doors. The stop 2 described in this embodiment is applicable to the door 11 connected by hinges 13.

[0040] Door 11 may include a front panel 111, a rear wall 112 facing the cabinet 10 when door 11 is closed, and a frame 113 disposed around the perimeter of door 11. For example, frame 113 may include a lower edge clip 1131 for defining the lower boundary of door 11 in the z-direction. In an example where door 11 is a refrigerator door, door 11 may include an insulated space filled with insulating material. When door 11 is closed, the insulating layer formed by the insulating space insulates against heat, ensuring optimal refrigeration / freezing performance of the storage compartment. The insulating space is located between the front panel 111 and the rear wall 112. In some embodiments, the front panel 111 forms at least a portion of the front boundary of the insulating space such that the insulating material contacts the rear side of the front panel 111. In other embodiments, another door panel may be provided on the rear side of the front panel 111. Front panel 111 may be a glass panel or a ceramic panel.

[0041] refer to Figure 1 and Figure 2The household appliance 1 includes a stop 2. The stop 2 is used to limit the maximum opening angle of the door 11. For example, the stop 2 can be located at the bottom edge 1131 of the door 11 and move with the opening and closing of the door 11. The stop 2 is adapted to cooperate with a hinge 13 to prevent the door 11 from continuing to open after reaching its maximum opening angle. For example, the hinge 13 includes a stop portion 132. During the opening process of the door 11, the door rotates about the axis O of the hinge axis of the hinge 13, and the stop 2 rotates synchronously about the axis O with the opening action of the door 11 until it contacts the stop portion 132. As the stop 2 interferes with the stop portion 132, even if the user applies force to the door 11 thereafter, the door 11 cannot continue to open due to the resisting action of the stop 2 and the stop portion 132. Thus, the maximum opening angle of the door 11 is limited by providing the stop 2.

[0042] Specifically, the stop member 2 includes a first side 2a and a second side 2b opposite to each other. The stop member 2 is positioned as follows: Figure 5 and Figure 6 When installed on door 11 as shown, the direction from the first side 2a to the second side 2b is parallel to the z-direction.

[0043] Furthermore, the stop member 2 includes a first stop edge 21 located on the first side 2a, used to limit the maximum opening angle of the door 11 to a first angle. The stop member 2 also includes a second stop edge 22 located on the second side 2b, used to limit the maximum opening angle of the door 11 to a second angle. The second angle is not equal to the first angle. That is, a single stop member 2 can achieve two different maximum opening angles. For example, the first angle can be taken from [115°, 130°]. As another example, the second angle can be taken from [85°, 95°].

[0044] Furthermore, the stop member 2 is rotatably installed on the door 11 so that one of the first stop edge 21 and the second stop edge 22 together provides a stopping function, while the stopping function of the other one is disabled. In other words, by changing the installation method of the stop member 2 on the door 1, it is possible to selectively enable one of the first stop edge 21 and the second stop edge 22, while preventing the other one from providing a stopping function.

[0045] For example, Figures 2 to 6 In the first embodiment shown, the first stop 21 is active, and the second stop 22 is inactive. As the door 11 opens, the first stop 21 can cooperate with the stop 132 to limit the maximum opening angle of the door 11 to a first angle. The first embodiment is illustrated by taking a first angle of 118° as an example. Accordingly, when the door 11 opens to such an angle... Figure 5 It cannot be opened any further after 118° as shown.

[0046] For example, Figures 8 to 10In the second embodiment shown, the stop 2 is installed by flipping it from the mounting direction of the second side 2b toward the door 11 shown in the first embodiment to the mounting direction of the first side 2a toward the door 11. In this example, the first stop 21 is disabled, and the second stop 22 is active. As the door 11 is opened, the second stop 22 can cooperate with the stop 132 to limit the maximum opening angle of the door 11 to a second angle. The second embodiment is exemplarily shown with the second angle being 90° as an example. Accordingly, when the door 11 is opened to such an angle... Figure 9 It cannot be opened any further after the 90° angle shown.

[0047] Therefore, by adopting this implementation scheme, two stop edges are integrated on the same stop member 2, allowing the door 11 to be optionally stopped at two maximum opening angles, better meeting the personalized needs of users. Based on the specific placement of the household appliance 1 in the home, the required maximum opening angle of the door 11 is determined, and thus the installation direction of the stop member 2 on the door 11 is determined, so that the stop edge corresponding to the required maximum opening angle can actually play a stopping role. This satisfies the personalized needs of different users.

[0048] Furthermore, simply flipping the stop piece 2 allows switching between different maximum door opening angles. This low complexity facilitates installation by workers in the user's home, shortening installation time. Even users can easily switch the maximum door opening angle themselves.

[0049] In some embodiments, reference Figures 2 to 6 In response to the stop member 2 being installed on the door 11 with its second side 2b facing the door 11, the first stop edge 21 acts as a stop. With this installation direction, the first side 2a of the stop member 2 is located on the side opposite to the door 11, so as to reliably engage with the stop part 132. If it is necessary to switch the maximum opening angle, the stop member 2 can be moved from... Figures 2 to 6 The posture shown is flipped to be as follows Figures 8 to 10 Install in the posture shown. (Reference) Figures 8 to 10 In response to the stop member 2 being installed on the door 11 with its first side 2a facing the door 11, the second stop edge 22 acts as a stop. With this installation direction, the second side 2b of the stop member 2 is located on the side opposite to the door 11, so as to reliably cooperate with the stop part 132. Thus, by activating the corresponding stop edge through the installation method, stopping at different angles can be achieved.

[0050] In a specific implementation, refer to Figure 3 , Figure 4 and Figure 9 The stop 2 may have an arc edge 2c, the center of which falls on the axis O of the hinge shaft. The edge of the hinge 13 may be configured to match the curvature of the arc edge 2c, and the arc edge 2c slides along the edge of the hinge 13 while the door 11 is opened from the closed position.

[0051] Furthermore, one end of the projection of the first stop edge 21 along the direction from the second side 2b to the first side 2a is located at the arc edge 2c. For ease of description, this end is referred to as the first end 211. That is, the first stop edge 21 terminates at the arc edge 2c. The first end 211 can be the end of the first stop edge 21 closer to the axis O. The first stop edge 21 may include a plane extending outward from the arc edge 2c to reliably achieve the stopping function by engaging with the surface of the stop portion 132.

[0052] Furthermore, one end of the projection of the second stop edge 22 along the direction from the second side 2b to the first side 2a is located at the arc edge 2c. For ease of description, this end is referred to as the second end 221. That is, the second stop edge 22 terminates at the arc edge 2c. The second end 221 can be the end of the second stop edge 22 closer to the axis O. The second stop edge 22 may include a plane extending outward from the arc edge 2c to reliably achieve the stopping function by engaging with the surface of the stop portion 132.

[0053] During the opening of door 11, the first end 211 and the second end 221 rotate with equal radius.

[0054] Furthermore, the first end 211 and the second end 221 are located at the two ends of the arc edge 2c along the extending direction, respectively. In other words, the first end 211 and the second end 221 form the end point of the arc edge 2c.

[0055] refer to Figure 3 The arc length of the first end 211 rotating around the axis O during the opening of the door 11 from the closed position to the first angle (equivalent to the first region 212) is different from the arc length of the second end 221 rotating around the axis O during the opening of the door 11 from the closed position to the second angle (equivalent to the second region 222). Thus, different maximum opening angles are limited.

[0056] In one specific implementation, of the first stop 21 and the second stop 22, the first stop 21 or the second stop 22 that acts as a stop protrudes from the door 11, while the first stop 21 or the second stop 22 that fails to stop does not protrude from the door 11. The stop that does not stop is flush with or recessed into the door 11 to prevent interference with the hinge 13 when the door 11 is opened, thus avoiding affecting the actual maximum opening angle of the door 11.

[0057] For example, Figure 5 and Figure 6 In the first embodiment shown, the first stop 21 protrudes downward along the z-direction from the lower edge latch 1131 of the door 11. At this time, the first stop 21 is in an active state and can cooperate with the stop part 132 to achieve a first angle limit. Furthermore, the second stop 22 does not protrude from the door 11 along the z-direction. As the door 11 is opened, the second stop 22 is located entirely above the hinge 13 and therefore cannot cooperate with the stop part 132.

[0058] For example, Figure 10 In the second embodiment shown, the second stop 22 protrudes downward along the z-direction from the lower latch 1131. As the door 11 opens, the second stop 22 can cooperate with the stop portion 132 of the hinge 13 located below the door 11 to achieve a second angle limit. Furthermore, the first stop 21 does not protrude from the door 11 along the z-direction. As the door 11 opens, the first stop 21 is entirely located above the hinge 13 and cannot cooperate with the stop portion 132.

[0059] In some embodiments, the first stop edge 21 and the second stop edge 22 that do not have a stopping effect can be hidden in the mounting groove 114 opened in the lower card 1131.

[0060] In a specific implementation, continue to refer to Figure 3 During the period from the closed position to the corresponding maximum opening angle, the area covered by the first stop 21 during its movement (denoted as the first region 212) and the area covered by the second stop 22 during its movement (denoted as the second region 222) at least partially overlap. The difference in the areas covered by the two stops during their movement achieves the stopping effect at different maximum opening angles.

[0061] Assuming the first angle is greater than the second angle, then the first region 212 is greater than the second region 222. The larger the area covered by the stop during movement, the larger the angle at which the door 11 can open, that is, the larger the maximum opening angle.

[0062] refer to Figure 6 Along the direction from the second side 2b to the first side 2a, the projection of the second stop 22 reaches the stop portion 132 before the projection of the first stop 21. The first end 211 and the second end 221 are both located on the arc edge 2c, and along the direction of movement of the first end 211 and the second end 221 when the door 11 is opened, the second end 221 is always located in front of the first end 211.

[0063] When the second stop 22 acts as a stop, since the second stop 22 reaches the stop part 132 before the first stop 21, the door 11 is restricted from further opening when it is opened to the second angle due to the cooperation between the second stop 22 and the stop part 132. Figure 10 As shown. At this point, the door 11 can no longer be opened to allow the first stop 21 to reach the stop 132.

[0064] When the first stop 21 acts as a stop, the projection of the second stop 22 reaches the stop portion 132 first, such as Figure 6 As shown. However, since the stopping function of the second stop 22 fails, the door 11 can continue to open at the second angle until the first stop 21 and the stop part 132 cooperate to restrict the door 11 at the first angle, as shown. Figure 5 As shown.

[0065] In one embodiment, the lower clip 1131 may be provided with a recessed mounting groove 114 facing inwards towards the door 11, the mounting groove 114 for receiving the stop 2. The mounting groove 114 may be a recessed groove. The blind hole design of the mounting groove 114 helps to prevent the insulation material filled inside the door 11 from overflowing.

[0066] Specifically, refer to Figure 2 and Figure 8 The lower clip 1131 may be provided with a groove 1133 recessed towards the inside of the door 11. The groove 1133 has a receiving hole 115 for receiving the hinge shaft of the hinge 13. The mounting groove 114 may be provided in parallel with the receiving hole 115 in the groove 1133. The groove 1133 may also be used to install the door closer 14.

[0067] The stop 2 and the door closer 14 can be installed together on the lower clip 1131. For example, the door closer 14 has multiple first mounting holes 141, the stop 2 has multiple second mounting holes 231, and the groove 1133 has multiple third mounting holes 1132. During assembly, multiple fasteners 29 are passed through the corresponding first mounting holes 141, second mounting holes 231, and third mounting holes 1132 in sequence to fix the door closer 14 and the stop 2 to the lower clip 1131.

[0068] In one specific implementation, the stop 2 can be an axisymmetric structure. In the direction from the first side 2a to the second side 2b, the outer contour of the projection of the stop 2 is close to a fan shape, and a stop edge is provided on both sides of the arc edge of the fan shape near the straight edge.

[0069] For household appliances 1 with multiple doors 11, such as a cross-door refrigerator, the stop 2 can be used on both the left and right doors 11. For example, Figure 3 Exemplary display stop 2 in Figure 1 The image shows the installation effect on the left and right hinged doors of a French double-door refrigerator. Therefore, making the stop part 2 a universal, standard part improves compatibility.

[0070] In some embodiments, the first angle is greater than the second angle, and the second stop 22 is closer to the side frame and the front panel 111 than the first stop 21. The side frame specifically refers to the frame 113 whose boundary along the x-direction is close to the hinge 13 side. The opening position of the mounting slot 114 in the slot 1133 is determined according to the relative position of the second stop 22 and the lower clip 1131.

[0071] In response to the stop 2 being installed in the mounting groove 114 with its second side 2b facing the door 11, the stop 2 fills the mounting groove 114, as... Figure 6 As shown. The mounting slot 114 is at least fully capable of accommodating the second side 2b to ensure that the second retaining edge 22 can be reliably held in the failure state.

[0072] In response to the stop 2 being installed in the mounting groove 114 with its first side 2a facing the door 11, a non-zero gap exists between the stop 2 and the mounting groove 114, such as... Figure 10 As shown. In order to fully accommodate the second side 2b, the outer contour of the mounting groove 114 projected along the z-direction completely covers and extends beyond the outer contour of the first side 2a projected along the z-direction. Therefore, when the second side 2b protrudes from the door 11 and is installed while the first side 2a is located within the mounting groove 114, there is a non-zero gap between the first stop 21 and the sidewall of the mounting groove 114. Furthermore, the second stop 22 protrudes from the door 11, so the gap between the first stop 21 and the sidewall of the mounting groove 114 is directly connected to the outside and is visible to the outside.

[0073] Therefore, regardless of whether the stop 2 actually acts as the first stop 21 or the second stop 22, the mounting groove 114 can reliably receive the stop 2, ensuring the reliability of the door 11's limit.

[0074] In one specific implementation, the first stop 21 and the second stop 22 have a height difference in the z-direction. Along the direction from the first side 2a to the second side 2b, the first stop 21 and the second stop 22 are formed at different heights of the stop member 2.

[0075] refer to Figure 7 The stop member 2 may include a mounting portion 23. The mounting portion 23 serves a fixing function. For example, a second mounting hole 231 may be formed in the mounting portion 23. The mounting portion 23 may be generally fan-shaped.

[0076] Furthermore, the stop member 2 may also include a first protrusion 24 extending from the mounting portion 23 toward the first side 2a. The first protrusion 24 may extend from the arcuate segment of the fan shape toward the first side 2a. A first stop edge 21 is formed on the first protrusion 24. For example, the first stop edge 21 is formed on the wall of the first protrusion 24 away from the center of the fan shape, the wall being parallel to the direction from the first side 2a toward the second side 2b.

[0077] Furthermore, the stop member 2 may also include a second protrusion 25 extending from the mounting portion 23 toward the second side 2b, and a protruding edge 26 extending from the second protrusion 25 toward a direction away from the mounting portion 23. The second protrusion 25 may extend from the arcuate segment of the fan shape toward the second side 2b. In a plane perpendicular to the direction from the first side 2a to the second side 2b, the protruding edge 26 extends from the second protrusion 25 toward a direction away from the center of the fan shape. A second stop edge 22 is formed on the protruding edge 26. For example, the second stop edge 22 is formed on the wall of the protruding edge 26 away from the center of the fan shape, the wall being parallel to the direction from the first side 2a to the second side 2b.

[0078] Therefore, the first stop 21 and the second stop 22 are offset from each other in the direction from the first side 2a to the second side 2b, ensuring that when the stop member 2 is installed on the door 11, only one of the two stops can always stop effectively.

[0079] Furthermore, the sidewalls of the corresponding fan-shaped straight segments of the protruding edge 26 are recessed inward to form an arc edge 2c.

[0080] In a plane perpendicular to the direction from the first side 2a to the second side 2b, the protruding edge 26 protrudes outward from the first protrusion 24 and the second protrusion 25.

[0081] It should be noted that the outer contour of the stop member 2 projected in the direction from the first side 2a to the second side 2b can be a fan shape or a polygonal structure that is close to a fan shape. For example, the wall of the first protrusion 24 forming the first stop edge 21 can be a plane. As another example, the wall of the protrusion 26 forming the second stop edge 22 can be a plane.

[0082] In a specific implementation, refer to Figure 6 The surface of the protruding edge 26 facing the first side 2a may be provided with a first mark 27, which is used to indicate a first angle. (See reference) Figure 7 The protruding edge 26 facing the second side 2b is provided with a second mark 28, which is used to indicate the second angle. Thus, the mark of the maximum opening angle and the corresponding stop are indicated on the same side, which makes it easy to identify the correct assembly posture during installation.

[0083] Although specific embodiments have been described above, these embodiments are not intended to limit the scope of this disclosure, even when only a single embodiment is described with respect to a particular feature. The feature examples provided in this disclosure are intended to be illustrative and not limiting, unless otherwise stated. In practice, one or more technical features of the dependent claims may be combined with technical features of the independent claims, and technical features from the respective independent claims may be combined in any suitable manner, not only by the specific combinations listed in the claims.

[0084] While the above disclosure is provided, it is not limited thereto. Any person skilled in the art may make various alterations and modifications without departing from the spirit and scope of this disclosure; therefore, the scope of protection of this disclosure shall be determined by the scope defined in the claims.
