Description

Technical Field

[0001] The present application relates to the field of oven accessories, and in particular to a suspension structure of an oven cover. Background Art

[0002] An oven, also known as a baking oven, toaster oven, or baking toaster, is a device that uses hot air to cook food. It's typically a closed or semi-enclosed structure. Traditional ovens use wood or coal for heating. Ovens are a common cooking device in everyday life, suitable not only for indoor cooking but also for outdoor cooking, bringing great convenience to people's cooking and dining lives.

[0003] In the related art, the oven includes an upper shell, a lower shell and a baking tray. Viewed from the vertical direction, the upper shell will be convex and the lower shell will be concave, and the opening edge of the upper shell will be hinged to the opening edge of the lower shell, so when the openings of the upper shell and the lower shell overlap, the upper shell and the lower shell will form a accommodating chamber, which is used for fuel combustion at the lower shell, and an ash outlet is provided at the lower shell. During the use of the oven, the ash outlet will be in a closed state, and the baking tray is set at the opening of the lower shell for placing food, so when roasting food, the upper shell and the lower shell need to be closed.

[0004] Regarding the above technical solution, there is a defect that since the hinge between the upper shell and the lower shell is a common hinge hinge, manual support is not required only when the angle between the upper shell and the lower shell is at the minimum angle or the maximum angle. When the upper shell needs to be opened to check the status of the food, it is necessary to support the upper shell by hand to make it hover, which is laborious and inconvenient when grilling food. Summary of the Invention

[0005] In order to enable the upper shell of the oven to hover at any position within a predetermined angle range, the present application provides a hovering structure of the oven cover.

[0006] The present application provides a suspension structure for a grill cover that adopts the following technical solutions:

[0007] A suspension structure for an oven cover includes a lower shell connecting frame, an upper shell connecting frame and a suspension member, wherein the lower shell connecting frame is connected to the lower shell of an external oven; the upper shell connecting frame is rotatably connected to the lower shell connecting frame, and the upper shell connecting frame is connected to the upper shell of the external oven; the suspension member is arranged on the lower shell connecting frame, and the suspension member is connected to the upper shell connecting frame, and the suspension member is used to enable the upper shell connecting frame to arbitrarily hover at a predetermined angle.

[0008] By adopting the above technical solution, due to the setting of the suspension part, when the upper shell of the oven needs to be opened during the process of grilling food in the oven, the upper shell connecting frame will rotate relative to the lower shell connecting frame. At the same time, the upper shell and the lower shell can be maintained at a predetermined angle through the action of the suspension part. With this design, after people open the upper shell, there is no need to always support the upper shell. Through the setting of the suspension part, the upper shell can be hovered within a predetermined angle range after opening, so that there is no need to always support the upper shell, which helps to improve the convenience of using the upper cover.

[0009] Preferably, the suspension member includes a mounting bracket, a suspension bracket, a suspension rod, a suspension ring, a shaft sleeve, a first gasket, a first spring and a second spring, the mounting bracket is arranged on the lower shell connecting bracket, and a mounting hole is provided on the mounting bracket; the suspension bracket is rotatably connected to the upper shell connecting bracket; the suspension rod is connected to one side surface of the suspension bracket, and the side of the suspension rod away from the suspension bracket will pass through the mounting hole, and the suspension ring is gap-sleeved on the suspension rod, and the suspension ring includes a mounting ring and an extrusion ring, the mounting ring abuts against the edge of the mounting hole near the hole on one side of the upper shell connecting bracket, the extrusion ring is connected to the inner ring edge of the mounting ring away from the side of the upper shell connecting bracket, the extrusion ring will extend into the mounting hole, and the The inner wall of the extrusion ring extends in the direction of the axis of the mounting hole; the sleeve is slidably mounted on the suspension rod, and the sleeve is used to abut against the inner wall of the extrusion ring on the side away from the upper shell connecting frame. A notch is provided on the circumferential side of the sleeve. When the sleeve abuts and slides against the inner wall of the extrusion ring, the inner diameter of the sleeve will change under the action of the notch; the first gasket is slidably mounted on the suspension rod, and the first gasket abuts and slides against the side of the sleeve away from the suspension ring; the first spring is mounted on the suspension rod, and the two ends of the first spring are respectively connected to the suspension frame and the mounting frame; the second spring is mounted on the suspension rod, and the two ends of the second spring are respectively connected to the suspension frame and the first gasket.

[0010] By adopting the above technical solution, since the suspension member includes a mounting frame, a suspension frame, a suspension rod, a suspension ring, a sleeve, a first gasket, a first spring and a second spring, when the upper shell needs to be opened, the upper shell connecting frame will rotate, and the suspension frame will move in the direction away from the mounting frame. At this time, the compression of the first spring and the second spring will decrease, and since the suspension frame rotates on the upper shell connecting frame, the axes of the first spring and the second spring can be made to coincide with the axis of the suspension rod during the rotation of the upper shell connecting frame. Since the compression of the second spring is reduced, the elastic force of the second spring on the first gasket will be reduced, so that the force acting on the sleeve in the direction away from the suspension frame will be reduced, so that the inner diameter of the sleeve When the upper shell is opened, the elastic force of the first spring and the second spring is increased, and the second spring moves the sleeve away from the suspension frame to reduce the inner diameter of the sleeve, thereby increasing the friction force between the sleeve and the suspension rod. As a result, during the rotation of the upper shell, the center of gravity of the upper shell changes, so that the elastic force of the first spring and the second spring is balanced with the friction force of the sleeve on the suspension rod and the gravity of the upper cover. Then, the upper shell can be suspended when it is opened, and when the upper shell is closed, the compression amount of the first spring and the second spring increases, and the second spring moves the sleeve away from the suspension frame to reduce the inner diameter of the sleeve, thereby increasing the friction force between the sleeve and the suspension rod. As a result, during the rotation of the upper shell, the first spring, the second spring, the sleeve and the upper shell are in a state of dynamic equilibrium, thereby forming a state of dynamic equilibrium between the suspension structure and the upper shell of the oven.

[0011] Preferably, the portion of the sleeve that contacts the extrusion ring is configured as an arc surface.

[0012] By adopting the above technical solution, due to the setting of the arc surface, when the sleeve abuts and slides on the inner wall of the extrusion ring, it can be avoided as much as possible that the sleeve causes wear to the inner wall of the extrusion ring when abutting and sliding, thereby avoiding as much as possible the impact on the friction between the sleeve and the hovering rod.

[0013] Preferably, a second gasket and an adjusting nut are provided on the suspension rod, the second gasket is sleeved on the side of the suspension rod close to the suspension frame, and the side of the second gasket away from the upper shell connecting frame is connected to the first spring and the second spring; the adjusting nut is threadedly connected to the suspension rod, and the adjusting nut abuts against the side of the second gasket away from the first spring.

[0014] By adopting the above technical solution, due to the arrangement of the second gasket and the adjusting nut, the position of the adjusting nut on the hovering rod can be changed by adjusting the threaded connection between the nut and the hovering rod according to different models of ovens. By changing the position of the second gasket on the hovering rod, the compression of the first spring and the second spring can be changed, thereby changing the initial elastic force of the first spring and the second spring, and thus making the hovering structure suitable for different types of ovens.

[0015] Preferably, a locking tube and a locking nut are provided on the suspension rod, and the locking tube is sleeved on the part of the suspension tube passing through the mounting hole, and one end face of the locking tube will abut against the mounting frame; the locking nut is threadedly connected to the side of the suspension rod away from the suspension frame, and the locking nut abuts against the other end face of the locking tube.

[0016] By adopting the above technical solution, due to the arrangement of the locking tube and the locking nut, when the locking tube and the locking nut are installed on the hovering rod, under the action of the locking tube, one end of the locking tube will press against the mounting frame, so that the hovering rod and the mounting frame remain in a relatively stationary state, so the compression amount of the first spring and the second spring will not change, thereby facilitating the storage and transportation of the hovering structure.

[0017] Preferably, a limiting hole is provided on the upper shell connecting frame; a limiting rod is provided on the lower shell connecting frame, and the limiting rod is passed through the limiting hole. When the upper shell connecting frame rotates, the limiting rod will be at different positions in the limiting hole.

[0018] By adopting the above technical solution, due to the setting of the limiting hole, when the upper shell connecting frame rotates relative to the lower shell connecting frame, the position of the limiting hole will also change accordingly. When the limiting rods are at the two ends of the limiting hole, it means that the upper shell connecting frame has rotated to the maximum angle position or the minimum angle position, thereby avoiding the phenomenon of the oven tipping over due to the upper shell rotating at a too large angle.

[0019] Preferably, a mounting plate is provided on the lower shell connecting frame, and two mounting plates are provided. The two mounting plates are arranged in a trumpet shape, and the trumpet-shaped openings of the two mounting plates are facing the suspension frame. A waist-shaped hole is provided on the mounting plate, and the extension direction of the waist-shaped hole extends toward the direction close to the suspension frame. An extension plate is provided on the mounting frame, and the extension plate is used to pass through the waist-shaped hole. When the mounting frame is installed, the waist-shaped hole is away from the side of the suspension frame for the extension plate to be set.

[0020] By adopting the above technical solution, due to the arrangement of the mounting plate, waist-shaped hole and extension plate, when the mounting frame is assembled and disassembled, it is only necessary to place the extension plate of the mounting frame on the side of the waist-shaped hole close to the suspension frame, and then slide the mounting frame in the direction of its own length away from the suspension frame. During the sliding process, the two ends of the extension plate of the mounting frame gradually pass through the two waist-shaped holes until the extension plate moves to the side of the waist-shaped hole away from the suspension frame. The inner walls of the two waist-shaped holes will respectively block the two ends of the extension plate. At the same time, under the action of the first spring and the second spring, the mounting frame can be installed on the lower shell connecting frame.

[0021] Preferably, a through slot is provided on the extension plate, and the inner side of the through slot is used for the side of the waist-shaped hole away from the suspension frame to be clamped.

[0022] By adopting the above technical solution, due to the setting of the through groove, when the extension plate is on the side of the waist-shaped hole away from the suspension frame, the edge of the side wall of the waist-shaped hole will be in the through groove, and the position of the mounting frame is restricted by the two side walls of the through groove, so as to avoid as much as possible the phenomenon of the mounting frame being offset due to the continuous opening and closing of the oven cover.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Due to the provision of the hovering member, when the upper shell of the oven needs to be opened during the grilling process, the upper shell connecting frame will rotate relative to the lower shell connecting frame. At the same time, the hovering member can maintain a predetermined angle between the upper shell and the lower shell. This design eliminates the need to constantly support the upper shell after opening it. The hovering member allows the upper shell to hover within a predetermined angle range after opening, eliminating the need to constantly support the upper shell, thereby helping to improve the convenience of using the upper cover.

[0025] 2. Because the suspension member includes a mounting frame, a suspension frame, a suspension rod, a suspension ring, a sleeve, a first gasket, a first spring and a second spring, when the upper shell needs to be opened, the upper shell connecting frame will rotate, and the suspension frame will move in a direction away from the mounting frame. At this time, the compression of the first spring and the second spring will decrease, and because the suspension frame rotates on the upper shell connecting frame, the axes of the first spring and the second spring can be made to coincide with the axis of the suspension rod during the rotation of the upper shell connecting frame. Because the compression of the second spring is reduced, the elastic force of the second spring on the first gasket is reduced, and the force acting on the sleeve in the direction away from the suspension frame is reduced, so that the inner diameter of the sleeve is increased. The friction between the shaft sleeve and the suspension rod will be reduced. At the same time, during the rotation of the upper shell, the center of gravity of the upper shell will change, so that the elastic force of the first spring and the second spring is balanced with the friction between the shaft sleeve and the suspension rod and the gravity of the upper cover. The upper shell can be suspended when it is opened. When the upper shell is closed, the compression of the first spring and the second spring increases, and the second spring moves the shaft sleeve away from the suspension frame, so that the inner diameter of the shaft sleeve is reduced, thereby increasing the friction between the shaft sleeve and the suspension rod. As a result, during the rotation of the upper shell, the first spring, the second spring, the shaft sleeve and the upper shell are in a state of dynamic equilibrium, thereby forming a state of dynamic equilibrium between the suspension structure and the upper shell of the oven.

[0026] 3. Due to the setting of the second gasket and the adjusting nut, when adjusting the position of the adjusting nut on the hovering rod according to different models of ovens, the threaded connection between the adjusting nut and the hovering rod can be adjusted to change the position of the second gasket on the hovering rod, thereby changing the compression of the first spring and the second spring, thereby changing the initial elastic force of the first spring and the second spring, and making the hovering structure suitable for different types of ovens.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses a suspension structure of a grill cover. Figure 1The upper shell connecting frame 2 is connected to the lower shell of the oven by screwing, and the upper shell connecting frame 2 is connected to the upper shell of the oven by screwing.

[0035] Reference Figure 1 The suspension member 3 includes a mounting frame 31, a suspension frame 32, a suspension rod 33, a suspension ring 34, a sleeve 35, a first gasket 36, a first spring 37 and a second spring 38. Specifically, the mounting frame 31 is arranged on the lower shell mounting frame 31. The mounting frame 31 is plate-shaped as a whole, but in other embodiments, it can also be other forms. A mounting hole 311 is opened in the middle position of the mounting plate 12. The cross-section of the mounting hole 311 is circular when viewed from the direction of the hole on one side of itself; the suspension frame 32 is a rectangular block as a whole, and one side of the suspension frame 32 is rotatably connected to the upper shell connecting frame 2 through a rotating shaft; the suspension rod 33 is a cylindrical rod, and the suspension rod 33 is The diameter is smaller than the diameter of the mounting hole 311, and one end face of the suspension rod 33 is fixedly connected to the side of the suspension frame 32 away from its own rotation connection. The side of the suspension rod 33 away from the suspension frame 32 will pass through the mounting hole 311, and when the suspension structure is installed on the oven, the axis of the suspension rod 33 will be in a vertical state, so when the upper shell connecting frame 2 rotates relative to the lower shell connecting frame 1, when the suspension frame 32 rotates with the upper shell connecting frame 2, the suspension frame 32 will also rotate under the action of the rotating shaft, so that when the suspension rod 33 slides under the action of the suspension frame 32, the axis of the suspension rod 33 can always remain in the vertical direction.

[0036] Reference Figure 1The cam 342 is screwed to the cam 343 and the cam 344 is screwed to the cam 343. The cam 342 is screwed to the cam 343 and the cam 344 is screwed to the cam 343. The cam 352 is provided with a groove 354 on the top of the cam 354 so that the cam 354 can slide on the cam 354 side of the shaft sleeve 35. The groove 354 is provided on the top of the cam 354 so that the cam 354 can slide on the cam 354 side of the shaft sleeve 35.

[0037] Reference Figure 1 A load-bearing ring 352 is integrally provided on the outer wall of the bearing of the sleeve 35; the first gasket 36 is annular, and the first gasket 36 is coaxially provided on the suspension rod 33, and the first gasket 36 abuts against the side of the load-bearing ring 352 close to the suspension frame 32 to carry the first gasket 36; the first spring 37 is coaxially provided on the suspension rod 33, and one end of the first spring 37 is fixedly connected to the mounting frame 31, and the other end is connected to the suspension frame 32, and the first spring 37 will always be in a compressed state; the second spring 38 is also coaxially provided on the suspension rod 33, and the inner diameter of the second spring 38 will be smaller than the inner diameter of the first spring 37. One end of the second spring 38 is fixedly connected to the side of the first gasket 36 away from the load-bearing ring 352, and the other end is connected to the suspension frame 32, and the second spring 38 will always be in a compressed state.

[0038] Reference Figure 1When the upper shell and the lower shell are closed, the compression of the first spring 37 and the second spring 38 will be at the maximum state, so the elastic force of the second spring 38 on the first gasket 36 will be at the maximum value. At this time, the second gasket 4 will make the sleeve 35 slide along the inner wall of the extrusion ring 342 to the farthest position away from the suspension frame 32, so that the inner diameter of the sleeve 35 is minimized, thereby making the friction between the sleeve 35 and the suspension rod 33 at the maximum state. When the upper cover needs to be opened, the upper shell connecting frame 2 rotates relative to the lower shell connecting frame 1 with the upper shell, and the upper shell connecting frame 2 will lead the suspension frame 32 to move in the vertical direction away from the mounting frame 31. At this time, the compression of the first spring 37 and the second spring 38 will be The elastic force of the first spring 37 on the suspension frame 32 will decrease, and the elastic force of the second spring 38 on the first gasket 36 and the suspension frame 32 will decrease, so that the friction between the sleeve 35 and the suspension rod 33 will decrease. At the same time, the center of gravity of the upper shell will change during the rotation of the upper shell, so that the gravity of the upper cover and the friction between the sleeve 35 and the suspension rod 33 and the elastic force of the first spring 37 and the second spring 38 on the suspension frame 32 will form a balanced state, so that the upper cover can be suspended within a predetermined angle range, and during the rotation of the upper shell, the first spring 37, the second spring 38, the sleeve 35 and the upper shell will be in a dynamic equilibrium state, so that the upper shell of the oven can be suspended at any position within the predetermined angle range.

[0039] Reference Figure 1 In order to limit the maximum rotation angle of the upper shell, a limiting hole 21 is provided on the upper shell connecting frame 2. The structure of the limiting hole 21 is waist-shaped, and the length direction of the limiting hole 21 is at a predetermined angle to the vertical direction; a limiting rod 11 is provided on the lower shell connecting frame 1. The limiting rod 11 is a cylindrical rod. The limiting rod 11 will pass through the limiting hole 21, so when the upper shell connecting frame 2 rotates, the limiting rod 11 will be at different positions of the limiting hole 21. When the limiting rod 11 is on both sides of the limiting hole 21, the upper shell will be at the maximum angle and the minimum angle, which is used to limit the rotation angle of the upper shell, so as to avoid the phenomenon that the oven rolls over due to the upper shell rotating at a too large an angle.

[0040] Reference Figure 1The second washer 4 is provided with a ring-shaped cover, and the second washer 4 is sleeved on the suspension rod 33. The second washer 4 is provided on the side of the suspension rod 33 close to the suspension frame 32, and the side of the second washer 4 away from the suspension frame 32 is provided with a stepped shape. The stepped parts of the second washer 4 are respectively used for fixing the first spring 37 and the second spring 38; the structural form of the adjusting nut 5 is an ordinary nut form. The adjusting nut 5 is threadedly connected to the side of the suspension rod 33 close to the suspension frame 32, and the adjusting nut 5 abuts against the side of the second washer 4 away from the first spring 37. Therefore, according to the specifications of the oven, the adjusting nut 5 can be adjusted to different positions of the suspension rod 33 to change the initial compression amount of the first spring 37 and the second spring 38, thereby changing the initial elastic force of the first spring 37 and the second spring 38, thereby making the suspension structure suitable for different types of ovens.

[0041] Reference Figure 1 When the cam 31 is unlocked, the locking nut 7 is tightened to the locking nut 7, so that the cam 31 is unlocked and the cam 31 is unlocked.

[0042] Reference Figure 1The cam 32 is provided with two cams 322 and a cam 323 which are connected to the support frame 31 of the second support structure 32. The cam 32 is provided with two cams 324 which are connected to the support frame 31 of the second support structure 32. When the waist-shaped hole is away from one side of the suspension frame 32, the two sides of the extension plate 312 will pass through the corresponding two waist-shaped holes respectively, and the inner walls of the waist-shaped holes will respectively block the two ends of the extension plate 312. At the same time, under the action of the first spring 37 and the second spring 38, the mounting bracket 31 can be mounted on the lower shell connecting frame 1. When the suspension structure needs to be disassembled, the compression amount of the first spring 37 and the second spring 38 is fixed by the locking tube 6 and the locking nut 7. Then, the upper shell connecting frame 2 is rotated to make the mounting bracket 31, the suspension rod 33 and the suspension frame 32 move synchronously, so that the mounting bracket 31 can be disassembled. In addition, through grooves 313 are provided on both sides of the extension plate 312. After the mounting bracket 31 is installed in place, the waist-shaped hole away from the side of the suspension frame 32 will be in the through groove 313, and the mounting bracket 31 is limited by the side walls of the through groove 313, which can minimize the phenomenon that the oven cover is constantly opened and closed and causes the mounting bracket 31 to be offset.

[0043] In addition, the suspension structure of the present application can be applied to ovens as well as other devices that need to be opened and closed.

[0044] The implementation principle of the hovering structure of the oven cover in an embodiment of the present application is: when the oven is in use, the hovering part 3 is set so that the upper shell can hover within a predetermined angle range when the upper shell is opened and closed, so there is no need to support the upper shell all the time, thereby helping to improve the convenience of using the upper cover.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
