Description

Technical Field

[0001] The present invention relates to an integrated stove component, in particular to an opening and closing mechanism of a decorative door under an integrated stove, belonging to the technical field of integrated stoves. Background Art

[0002] In order to improve the utilization rate of the internal space of the integrated stove, many integrated stove products currently have a water box or a storage box at the bottom of the body. Accordingly, the shell wall at the bottom of the body is designed with a lower door frame mechanism that can be opened and closed to facilitate the placement and removal of the water box or the storage box.

[0003] The conventional opening and closing mechanism of an integrated under-stove decorative door includes a door frame, a door panel, and a locking member. The locking member locks and unlocks the door frame and door panel to achieve opening and closing. Therefore, researching and developing an integrated under-stove decorative door opening and closing mechanism that facilitates user-friendly door panel opening and closing is of great significance to the field. Summary of the Invention

[0004] Based on the above background, the purpose of the present invention is to provide an integrated under-stove decorative door opening and closing mechanism, which allows users to open and close the door panel conveniently and quickly.

[0005] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0006] An integrated under-stove decorative door opening and closing mechanism includes a door frame assembly and a door panel assembly. The door frame assembly is provided with one of a lock catch and a lock box assembly. The door panel assembly is provided with the other of a lock catch and a lock box assembly. The lock box assembly is used to lock the lock catch. The lock box assembly includes:

[0007] A box body, the box body having an inner cavity, the box body being provided with a lock hole communicating with the inner cavity of the box body and the outside of the box body, the lock hole being capable of allowing at least a portion of the locking member to pass through;

[0008] A top block is disposed inside the box body and opposite to the lock hole, and the top block can move between a first position away from the lock hole and a second position adjacent to the lock hole;

[0009] a first elastic member, the first elastic member being used to provide a rebound force to the top block so that the top block has a movement tendency from the first position to the second position;

[0010] a locking member disposed inside the box body, the locking member being provided with a blocking portion for fixing at least a portion of the lock member inside the box body, the locking member being movable between a third position and a fourth position relative to the box body; when the locking member is in the third position, at least a portion of the blocking portion abuts against the lock member, thereby preventing the lock member from moving inside the box body; when the locking member is in the fourth position, the blocking portion is located away from a movement path of the lock member inside the box body, and the top block is in the second position, a side portion of the top block abuts against the blocking portion, thereby preventing the locking member from moving from the fourth position to the third position;

[0011] a second elastic member disposed inside the box body, for providing a rebound force to the locking member so that the locking member has a movement tendency from the fourth position to the third position;

[0012] A limit member is provided inside the box body, and the limit member can move between a fifth position and a sixth position relative to the box body; when the limit member is in the fifth position, the limit member abuts against a side of the locking member that is away from the blocking portion, thereby preventing the locking member from moving from the third position to the fourth position; when the limit member is in the sixth position, the limit member disengages from the side of the locking member that is away from the blocking portion, and the locking member is in the fourth position.

[0013] When the door is closed, the first resilient member is engaged with the latch and the latch box assembly so that the door panel assembly and the door frame assembly can be opened or closed. When the door is closed, the latch is inserted into the lock hole, and the latch pushes the top block from the second position into the first position. The position change of the top block also causes the first elastic member to deform and cause the side of the top block to disengage the blocking portion of the lock member from the abutment relationship. At this time, the lock member moves from the fourth position to the third position under the action of the second elastic member, and the blocking portion of the lock member cooperates with the latch to lock it. At the same time, the limit member moves to the fifth position, abuts against the lock member, thereby limiting the position of the lock member to keep the blocking portion locked to the latch member; in the closed state, the deformation of the first elastic member generates a rebound force to the top block, so that the top block has a movement tendency from the first position to the second position, thereby causing the latch to have a movement tendency to be pushed out of the lock hole by the top block, but this movement tendency is due to the locking of the limit member on the lock Thus, the user only needs to perform a shifting operation on the limiting member to move the limiting member from the fifth position to the sixth position, at which time the limiting member releases the abutment against the locking member, stopping the movement tendency of the lock catch member being pushed out of the lock hole by the push block, and the push block is moved from the first position to the second position under the action of the rebound force of the first elastic member, and the lock catch member is pushed out of the lock hole. In the process of the lock catch being pushed out, the displacement of the lock catch member causes the lock member to move from the third position to the fourth position until the side of the top block abuts the blocking portion. At this time, the deformation of the second elastic member generates a rebound force to the lock member so that it has a movement tendency from the fourth position to the third position, but this movement tendency is stopped due to the abutment of the side of the top block against the blocking portion. Thus, the user can conveniently and quickly open the door panel assembly locked to the door frame assembly by only performing a shifting operation on the limiting member.

[0014] Preferably, the limiting member includes a rod and a limiting portion, the rod is slidably connected to the box body, the limiting portion is connected to one end of the rod, and the limiting portion protrudes from the side wall of the rod. When the limiting member is in the fifth position, the limiting portion abuts against the side of the locking member that is away from the blocking portion.

[0015] Preferably, a portion of the limiting portion that contacts the locking member when the limiting member is in the fifth position is provided with an arc-shaped chamfer.

[0016] Preferably, the inner wall of the box body is provided with a first slide groove, the first slide groove extending from the fifth position of the limiter toward the sixth position, the limiter further comprising a slider portion protruding from the side wall of the limiter, the limiter being slidably connected to the first slide groove via the slider portion. With this technical solution, the first slide groove defines the sliding trajectory of the slider portion, allowing the limiter to move along a predetermined sliding path while preventing the limiter from making unpredictable displacement relative to the box body.

[0017] Preferably, the box body is provided with a button and a third elastic member, the button being embedded in the box body and being able to move between a seventh position and an eighth position relative to the box body; when the button is in the seventh position, one end of the button abuts against the end of the rod away from the limiting portion, thereby causing the limiting member to have a movement tendency from the fifth position to the sixth position; when the button is in the eighth position, the button is away from the limiting member; the third elastic member is used to provide a rebound force to the button so that the button has a movement tendency from the seventh position to the eighth position, one end of the third elastic member abuts against the box body, and the other end of the third elastic member abuts against the button. Through the above technical solution, it is convenient for the user to shift the limiting member through the button, and the third elastic member enables the button to be quickly reset after being pressed.

[0018] Preferably, a pressure plate is provided within the box body, the pressure plate being connected to the inner wall of the box body, and a retaining groove is provided on the surface of the pressure plate adjacent to the inner wall of the box body, and the retaining member is at least partially disposed within the retaining groove. Through the above technical solution, the pressure plate further restricts the movement of the retaining member along the set sliding path, thereby preventing the retaining member from making unset displacement relative to the box body.

[0019] Preferably, the inner wall of the box body is provided with a second slide groove, the second slide groove extending from the second position of the top block to the first position, the second slide groove being connected to the lock hole, the top block being disposed in the second slide groove and being able to slide along the second slide groove, and a notch being provided on the side wall of the second slide groove on the movement path of the locking member from the fourth position to the third position, the notch being able to allow the blocking portion to pass through. Through the above technical solution, the second slide groove defines the sliding trajectory of the top block, allowing the top block to move according to the set sliding path, while preventing the top block from making unset displacement relative to the box body.

[0020] Preferably, the surface of the top block adjacent to the side wall of the second chute has at least one inclined surface, and the distance between the end of the inclined surface away from the lock hole and the side wall of the second chute is smaller than the distance between the end of the inclined surface adjacent to the lock hole and the side wall of the second chute. This technical solution reduces the frictional resistance between the side wall of the top block and the second chute during movement, allowing the top block to slide more smoothly within the second chute.

[0021] Preferably, the locking member is provided with a rotating shaft at the end opposite the blocking portion, and the locking member is hingedly connected to the box body via the rotating shaft, with the central axis of the hinged connection between the locking member and the box body being perpendicular to the movement path of the locking member within the box body. The rotating shaft can be a separate component and pass through the locking member, or it can be integrally formed with the locking member and protrude from the side of the locking member.

[0022] Preferably, the blocking portion protrudes from the side surface of the locking member, has a flat surface on one side and an arcuate surface on the other side, and when the locking member is in the third position, the flat surface of the blocking portion abuts against the latch. This technical solution improves the smoothness of the blocking portion as it moves with the locking member, and reduces the area where the blocking portion interferes with other components.

[0023] Preferably, the first elastic member comprises a compression spring, one end of the compression spring abuts against the inner wall of the box body, and the other end of the compression spring abuts against the top block.

[0024] Preferably, the second elastic member includes a torsion spring, which is sleeved on the surface of the rotating shaft, with one end of the torsion spring abutting against the inner wall of the box body, and the other end of the torsion spring being located on the movement path of the locking member from the third position to the fourth position.

[0025] Preferably, a rotary hinge is provided between the door frame assembly and the door panel assembly, and the door frame assembly is hinged to the door panel assembly via the rotary hinge.

[0026] Preferably, the rotary hinge includes a hinge support, a swing arm, and a damping shaft.

The hinge support is provided with a first hinge hole, and the swing arm is provided with a second hinge hole. One end of the damping shaft is mounted in the first hinge hole, and the other end of the damping shaft is mounted in the second hinge hole. Through the above technical solution, the damping shaft provides resistance to the relative rotational movement of the door frame assembly and the door panel assembly, making the opening and closing movement of the door panel assembly smoother.

DETAILED DESCRIPTION

[0048] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of the present invention is not limited to the following embodiments, and any form of modification and / or change made to the present invention will fall within the scope of protection of the present invention.

[0049] In the present invention, unless otherwise specified, all parts and percentages are by weight. The equipment and raw materials used are commercially available or commonly used in the art. The methods in the following embodiments, unless otherwise specified, are conventional methods in the art. The components or equipment in the following embodiments, unless otherwise specified, are all universal standard parts or components known to those skilled in the art. Their structures and principles are known to those skilled in the art through technical manuals or routine experimental methods.

[0050] An embodiment of the present invention discloses an opening and closing mechanism for an integrated under-stove decorative door, comprising a door frame assembly 1 and a door panel assembly 2. The door frame assembly 1 is provided with one of a latch 3 and a latch box assembly 4. The door panel assembly 2 is provided with the other of the latch 3 and latch box assembly 4. The latch box assembly 4 is used to lock the latch 3. The latch box assembly 4 includes a housing, a top block 43, a first elastic member, a locking member 45, a second elastic member, and a stopper 47. The housing has an interior cavity and a lock hole 40 connecting the interior cavity with the exterior of the housing. The lock hole 40 allows at least a portion of the latch 3 to pass through. The top block 43 is disposed within the housing and opposite the lock hole 40. The top block 43 is movable between a first position away from the lock hole 40 and a second position adjacent to the lock hole 40. The first elastic member is used to provide a rebound force to the top block 43, thereby causing the top block 43 to tend to move from the first position to the second position. The locking member 45 is disposed within the housing and includes a blocking portion 451 for securing at least a portion of the latch 3 within the housing. The locking member 45 is movable between a third position and a fourth position relative to the housing. When the locking member 45 is in the third position, at least a portion of the blocking portion 451 abuts against the latch 3, thereby preventing the latch 3 from moving within the housing. When the locking member 45 is in the fourth position, the blocking portion 451 is located away from the movement path of the latch 3 within the housing, and the top block 43 is in the second position. The side of the top block 43 abuts against the blocking portion 451, preventing the locking member 45 from moving from the fourth position to the third position. A second elastic member is disposed within the housing to provide a rebound force to the locking member 45, thereby ensuring that the locking member 45 has a tendency to move from the fourth position to the third position. A stopper 47 is disposed within the housing and is movable relative to the housing between a fifth position and a sixth position. When in the fifth position, the stopper 47 abuts against the side of the locking member 45 facing away from the blocking portion 451, thereby preventing the locking member 45 from moving from the third position to the fourth position. When in the sixth position, the stopper 47 disengages from the side of the locking member 45 facing away from the blocking portion 451, and the locking member 45 is in the fourth position. Through the interaction of the various components within the striker housing assembly 4, the user can quickly and easily open the door panel assembly 2 locked to the door frame assembly 1 by simply shifting the stopper 47.

[0051] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following detailed description, for the convenience of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present invention.

[0052] refer to Figure 1-2 The invention discloses an opening and closing mechanism for an integrated under-stove decorative door, comprising a door frame assembly 1 and a door panel assembly 2. The door panel assembly 2 is provided with a lock 3, and the door frame assembly 1 is provided with a lock box assembly 4 for locking the lock 3. Of course, the positions of the lock 3 and the lock box assembly 4 can be interchanged.

[0053] The locking member 3 is provided with a through-hole 31 for insertion into and locking with the locking box assembly 4. Alternatively, the locking member 3 may be provided with a protrusion protruding from its surface, which can also be inserted into and locked with the locking box assembly 4. Alternatively, the locking member 3 may employ other structures that can cooperate with the internal components of the locking box assembly 4 to achieve locking.

[0054] refer to Figure 3-6 The lock box assembly 4 includes a box body, a top block 43, a first elastic member, a locking member 45, a second elastic member, and a limiting member 47. The top block 43 is movable relative to the box body between a first position and a second position. In the first position, the top block 43 is away from the locking hole 40 described below. In the second position, the top block 43 is adjacent to the locking hole 40. The locking member 45 is movable relative to the box body between a third position and a fourth position. In the third position, the locking member 45 engages with the locking hole 31 of the locking member 3, thereby locking the locking member 3. In the fourth position, the locking member 45 disengages from the locking hole 31 of the locking member 3, thereby releasing the locking member 3. The limiting member 47 is movable relative to the box body between a fifth position and a sixth position. In the fifth position, the limiting member 47 abuts the locking member 45 to maintain the locking member 45 in the third position. In the sixth position, the limiting member 47 releases the abutment against the locking member 45, allowing the locking member 45 to move freely to the fourth position. Figure 3 and Figure 4 The structure and component positions of the lock box assembly 4 and the lock member 3 in the locked state are shown. At this time, the top block 43 is in the first position, the locking member 45 is in the third position, and the limiting member 47 is in the fifth position. Figure 5 and Figure 6 The structure and component positions of the lock box assembly 4 and the lock member 3 in the unlocked state are shown. At this time, the top block 43 is in the second position, the locking member 45 is in the fourth position, and the limiting member 47 is in the sixth position.

[0055] refer to Figure 7 The box body has an inner cavity, and a lock hole 40 is provided connecting the inner cavity with the outer cavity. The lock hole 40 allows at least a portion of the locking member 3 to pass through. Specifically, the box body includes a base 41 and a lid 42. The inner cavity is formed on the base 41. The base 41 and the lid 42 are detachably connected by fasteners to seal the inner cavity within the box body. The lock hole 40 is a rectangular through hole and is provided on the base 41.

[0056] The top block 43 is disposed inside the box body and opposite to the locking hole 40 . The top block 43 can move between a first position away from the locking hole 40 and a second position adjacent to the locking hole 40 . Specifically, the top block 43 is slidably connected to the base 41 .

[0057] refer to Figure 8To prevent the top block 43 from performing unintended displacement relative to the box body, a second chute 411 is provided within the inner cavity of the base 41. The second chute 411 extends from the second position of the top block 43 toward the first position and is connected to the lock hole 40. The top block 43 is disposed within the second chute 411 and is capable of sliding along the second chute 411. The second chute 411 defines the sliding trajectory of the top block 43, allowing the top block 43 to move along the predetermined sliding path. To facilitate the movement of the locking member 45, a notch 412 is provided on the sidewall of the second chute 411, which is located along the path of movement of the locking member 45 from the fourth position to the third position. The notch 412 allows the blocking portion 451 of the locking member 45, described below, to pass through. To facilitate the connection of the locking member 45, a hinge seat 413 protruding from the sidewall of the second chute 411, where the notch 412 is located, is provided. The hinge seat 413 is provided with a mounting hole to accommodate the hinged locking member 45.

[0058] refer to Figure 9-10 The surface of the top block 43 for contacting the locking member 3 is a plane, and the other surface of the top block 43 opposite to the plane is provided with three grooves, each of which is provided with a first elastic member. Of course, the number of grooves and first elastic members can be adjusted as needed. Figure 10 To reduce frictional resistance between the sidewalls of the top block 43 and the second chute 411 during movement, thereby ensuring smoother sliding of the top block 43 within the second chute 411, the surface of the top block 43 adjacent to the sidewalls of the second chute 411 has two inclined surfaces. These two inclined surfaces are arranged opposite each other, forming a trapezoidal cross-sectional projection of the top block 43. The distance between the end of the inclined surface facing away from the keyhole 40 and the sidewall of the second chute 411 is smaller than the distance between the end of the inclined surface adjacent to the keyhole 40 and the sidewall of the second chute 411. Of course, the number of inclined surfaces can be adjusted as needed, as long as at least one is provided.

[0059] The first elastic member is provided between the top block 43 and the inner wall of the box body, and the first elastic member is used to provide a rebound force to the top block 43 so that the top block 43 has a movement tendency from the first position to the second position. Figure 8 The first elastic member includes a compression spring 44 , one end of the compression spring 44 abuts against the box cover 42 , and the other end of the compression spring 44 abuts against the bottom surface of the groove of the top block 43 .

[0060] refer to Figure 11The locking member 45 is disposed within the housing. It includes a blocking portion 451 that engages with the buttonhole 31 to secure a portion of the locking member 3 within the housing. When the locking member 45 is in the third position, at least a portion of the blocking portion 451 abuts the locking member 3, thereby preventing the locking member 3 from moving within the housing. When the locking member 45 is in the fourth position, the blocking portion 451 is located away from the movement path of the locking member 3 within the housing, and the top block 43 is in the second position. The side of the top block 43 abuts the blocking portion 451, preventing the locking member 45 from moving from the fourth position to the third position. Specifically, the blocking portion 451 protrudes from the side surface of the locking member 45. One side of the blocking portion 451 is flat, and the other side is curved, giving the entire locking member 45 a hook-like shape. This improves the smoothness of the blocking portion 451 as it moves with the locking member 45 and reduces the area where the blocking portion 451 interferes with other components. When the locking member 45 is at the third position, the blocking portion 451 has a flat side that abuts against the locking member 3 .

[0061] Reference again Figure 4 、 Figure 6 and Figure 7 The locking member 45 has a rotating shaft 452 at the end opposite the blocking portion 451. The locking member 45 is hinged to the housing via the rotating shaft 452. The central axis of the hinged connection between the locking member 45 and the housing is perpendicular to the movement path of the latch 3 within the housing. In this embodiment, the rotating shaft 452 is a separate component and extends through the locking member 45. Of course, the rotating shaft 452 can also be integrally formed with the locking member 45 and protrude from the side of the locking member 45.

[0062] The second elastic member is provided inside the box body, and is used to provide a rebound force to the locking member 45 so that the locking member 45 has a movement tendency from the fourth position to the third position. Figure 8 The second elastic member includes a torsion spring 46, which is sleeved on the surface of the rotating shaft 452. One end of the torsion spring 46 abuts against the box cover 42, and the other end of the torsion spring 46 is in the movement path of the locking member 45 from the third position to the fourth position. Therefore, when the locking member 45 moves from the third position to the fourth position, the locking member 45 applies force to the other end of the torsion spring 46 to cause the torsion spring 46 to produce elastic deformation.

[0063] refer to Figure 12 , and combined with reference Figure 3 and Figure 5The limiting member 47 is disposed inside the box body. When the limiting member 47 is in the fifth position, the limiting member 47 abuts against the side of the locking member 45 that is away from the blocking portion 451, thereby preventing the locking member 45 from moving from the third position to the fourth position. When the limiting member 47 is in the sixth position, the limiting member 47 disengages from the side of the locking member 45 that is away from the blocking portion 451, and the locking member 45 is in the fourth position. Specifically, the limiting member 47 includes a rod 471 and a limiting portion 472. The rod 471 is slidably connected to the box body, and the limiting portion 472 is connected to one end of the rod 471. The limiting portion 472 protrudes from the side wall of the rod 471. When the limiting member 47 is in the fifth position, the limiting portion 472 abuts against the side of the locking member 45 that is away from the blocking portion 451.

[0064] It should be noted that the lock box assembly 4 of this embodiment is arranged on the door frame assembly 1 in a direction roughly perpendicular to the ground, and the movement direction of the limit member 47 from the sixth position to the fifth position is also roughly perpendicular to the ground. Therefore, the movement of the limit member 47 from the sixth position to the fifth position is caused by its own gravity. Of course, when the setting method of the lock box assembly 4 or the setting method of the limit member 47 cannot make the limit member 47 move from the sixth position to the fifth position by its own gravity, those skilled in the art can add an elastic reset member to provide a driving force for the limit member 47 from the sixth position to the fifth position. The elastic reset member can be a spring or other elastic component. Its structure and setting method belong to the existing technology in this field and will not be repeated here.

[0065] In order to improve the smoothness of movement of the limiting member 47 from the sixth position to the fifth position, the limiting portion 472 is provided with an arc-shaped chamfer at the position where the limiting member 47 abuts against the locking member 45 when the limiting member 47 is in the fifth position.

[0066] Reference again Figure 8 , and combined with reference Figure 12 To prevent the limiter 47 from unintended displacement relative to the housing, a first slide groove 414 is provided on the inner wall of the housing. The first slide groove 414 extends from the fifth position of the limiter 47 toward the sixth position. The limiter 47 also includes a slider 473 that protrudes from the sidewall of the limiter 47 and is slidably connected to the first slide groove 414 via the slider 473. The first slide groove 414 defines the sliding path of the slider 473, allowing the limiter 47 to move along the predetermined sliding path.

[0067] refer to Figure 13 , and combined with reference Figure 8In order to further limit the movement of the limiting member 47 according to the set sliding path, a pressure plate 415 is provided inside the box body, and the pressure plate 415 is connected to the inner wall of the box body. The surface of the pressure plate 415 adjacent to the inner wall of the box body is provided with a limiting groove 4151 recessed in the surface of the pressure plate 415, and the limiting member 47 is at least partially arranged in the limiting groove 4151.

[0068] Reference again Figure 8 , and combined with reference Figure 3 and Figure 5 In order to facilitate the user to perform the shift operation of the limit member 47 through the button 48, the box body is provided with a button 48 and a third elastic member. The button 48 is embedded in the box body, and the button 48 can move between the seventh position and the eighth position relative to the box body. When the button 48 is in the seventh position, one end of the button 48 abuts against the end of the rod 471 away from the limit portion 472, so that the limit member 47 has a movement trend from the fifth position to the sixth position. When the button 48 is in the eighth position, the button 48 is away from the limit member 47. The third elastic member is used to provide a rebound force to the button 48 so that the button 48 has a movement trend from the seventh position to the eighth position. One end of the third elastic member abuts against the box body, and the other end of the third elastic member abuts against the button 48. The third elastic member enables the button 48 to be quickly reset after being pressed. In this embodiment, a cylindrical member 416 protruding from the outer wall of the box body is provided at the bottom of the box body, and the cylindrical member 416 is connected to the inside of the box body. Figure 14 The key 48 includes a key cap 481 and a top post 482 connected to the key cap 481. The outer diameter of the key cap 481 is larger than the outer diameter of the top post 482. The key cap 481 is embedded in the cylindrical member 416. The top post 482 extends into the interior of the box body. The cylindrical member 416 is used to limit the key 48. Figure 15 The third elastic member includes a key spring 49 sleeved outside the top column 482, and the key spring 49 is located between the key cap 481 and the bottom surface of the cylindrical member 416.

[0069] Of course, the button 48 and the third elastic member may not be provided, and the rod 471 of the limiting member 47 may be provided to extend outside the box body, and the displacement operation of the limiting member 47 may also be achieved by pressing the end of the rod 471.

[0070] Reference again Figure 1 and Figure 2 The integrated under-stove decorative door opening and closing mechanism of this embodiment includes a rotary hinge 5 between the door frame assembly 1 and the door panel assembly 2. The door frame assembly 1 is hingedly connected to the door panel assembly 2 via the rotary hinge 5 to enhance the convenience of opening and closing the door frame assembly 1 and the door panel assembly 2. Of course, depending on actual needs, the door frame assembly 1 and the door panel assembly 2 may be connected without the rotary hinge 5, and other connection methods such as snap-fit ​​or buckle connection may be employed.

[0071] refer to Figure 16-17The rotary hinge 5 includes a hinge support 51, a swing arm 52, and a damping shaft 53. The hinge support 51 is fixedly connected to the door frame assembly 1, and the swing arm 52 is fixedly connected to the door panel assembly 2. Alternatively, the hinge support 51 is fixedly connected to the door panel assembly 2, while the swing arm 52 is fixedly connected to the door frame assembly 1. The hinge support 51 has a first hinge hole 54, and the swing arm 52 has a second hinge hole 55. One end of the damping shaft 53 is mounted in the first hinge hole 54, and the other end of the damping shaft 53 is mounted in the second hinge hole 55. The damping shaft 53 provides resistance to the relative rotational motion of the door frame assembly 1 and the door panel assembly 2, making the opening and closing motion of the door panel assembly 2 smoother.

[0072] The door panel assembly 2 and the door frame assembly 1 are opened or closed by cooperating with the lock catch 3 and the lock box assembly 4. When closing, the lock catch 3 is inserted into the lock hole 40, and the lock catch 3 pushes the top block 43 from the second position to the first position. The position change of the top block 43 also causes the first elastic member to deform, and the side of the top block 43 is disengaged from the abutment relationship with the blocking portion 451 of the lock member 45. At this time, the lock member 45 moves from the fourth position to the third position under the action of the second elastic member, and the blocking portion 451 of the lock member 45 cooperates with the lock catch 3 to lock it. At the same time, the limit member 47 moves to the fifth position, abutting the lock member 45 so that the position of the lock member 45 is limited, so as to keep the blocking portion 451 locking the lock member 3.

[0073] In the closed state, the deformation of the first elastic member generates a rebound force to the top block 43, so that the top block 43 has a movement tendency from the first position to the second position, thereby causing the locking member 3 to have a movement tendency to be pushed out of the lock hole 40 by the top block 43, but this movement tendency is curbed due to the abutment of the limit member 47 on the locking member 45.

[0074] When opening, the user only needs to press the button 48 to shift the limit member 47 to move the limit member 47 from the fifth position to the sixth position. At this time, the limit member 47 releases the abutment against the locking member 45, and stops curbing the movement trend of the lock member 3 being pushed out of the lock hole 40 by the top block 43. The top block 43 moves from the first position to the second position under the action of the rebound force of the first elastic member, and the lock member 3 is pushed out of the lock hole 40. In the process of the lock member 3 being pushed out, the displacement of the lock member 3 causes the lock member 45 to move from the third position to the fourth position until the side of the top block 43 abuts against the blocking portion 451. At this time, the deformation of the second elastic member generates a rebound force to the lock member 45, causing it to have a movement trend from the fourth position to the third position, but this movement trend is curbed due to the abutment of the side of the top block 43 against the blocking portion 451.

[0075] Therefore, the user only needs to shift the limiting member 47 to conveniently and quickly open the door panel assembly 2 locked to the door frame assembly 1.

[0076] It should be pointed out that the opening and closing mechanism of the decorative door under the integrated stove according to the embodiment of the present invention can be applied not only to the opening and closing of the decorative door under the integrated stove body, but also to the opening and closing of door panels of other types of cabinets or bodies.

[0077] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
