Description

Technical Field

[0001] This utility model relates to the field of ovens, and more particularly to an oven with a stable upward-opening door. Background Technology

[0002] An oven is a common kitchen appliance, mainly used for baking, roasting, and heating food.

[0003] In existing technology, oven doors and ovens are typically connected by hinges, and oven doors are usually either left- or right-flipping doors or downward-flipping doors. For example, the oven door assembly with a convenient detachable handle and the oven door in the oven described in utility model patent CN219672358U are downward-flipping oven doors, which include an oven door body, a handle, and a detachable mounting component. The detachable mounting component includes a mounting part on the handle, a limiting part opposite to the mounting part, and a connecting part connecting the mounting part and the limiting part. The mounting part, the limiting part, and the connecting part together form an insertion groove for the oven door body to extend into. When the oven door body extends into the insertion groove, pulling the handle causes the limiting part to abut against the oven door body, pushing the oven door body forward to flip, or pushing the handle causes the mounting part to abut against the oven door body, pushing the oven door body backward to open and close the oven door. Both left- or right-flipping and downward-flipping doors require considerable space to open and close. When kitchen space is limited, the opening and closing of the oven door can be restricted, affecting the use of the oven. Meanwhile, the hinges are prone to wear due to the weight of the oven door and frequent opening and closing, leading to decreased door sealing and affecting the oven's heat retention. Furthermore, dirt easily accumulates in the gaps between the oven door and the hinges, making cleaning relatively difficult. When the oven door is a flip-down door, the following disadvantages also exist: the flip-down door tilts downwards when opened, potentially contacting the countertop or floor below, affecting cleaning and use. Also, if the door is not closed properly, it may accidentally open during use, causing heat leakage or food to fall out. Summary of the Invention

[0004] In view of this, the present invention provides an oven with a stable upward-opening door to solve the above problems.

[0005] An oven with a stable upward-opening door includes an oven body, an oven door movably disposed on one side of the oven body, and two flip-up connecting mechanisms for connecting the oven body and the oven door. The oven door includes a door body fixedly connected to the flip-up connecting mechanism, a handle disposed on the door body, and two connecting brackets symmetrically disposed on both sides of the door body. Each flip-up connecting mechanism includes a rotating component fixedly connected to the oven door, a pulling component connected to the rotating component, and a limiting member located on one side of the rotating component. The door body is fixedly connected to the rotating component via the connecting brackets. The connecting brackets are located at one-third of the distance from the top of the oven body on the side of the door body closest to the top. The rotating component includes a support cylinder fixedly disposed on the oven body, a rotating shaft passing through the support cylinder, and a pulling connecting component disposed at one end of the rotating shaft. The pulling component includes a mounting plate fixedly disposed on the oven body, a spring mounting member fixedly disposed vertically on the mounting plate, and a tension spring connected to the spring mounting member. The central axis of the spring mounting component is perpendicular to and intersects the central axis of the rotation axis. One end of the tension spring is connected to the spring mounting component, and the other end is connected to the tension connection assembly.

[0006] Furthermore, the traction connection assembly includes a connector body and a connecting shaft fixedly mounted on the connector body.

[0007] Furthermore, the connecting bracket is located at one-third of the way down the side of the door closest to the top of the oven body.

[0008] Furthermore, the handle is positioned horizontally on the side of the door facing the ground.

[0009] Furthermore, a limiting annular groove is provided at the end of the connecting shaft away from the housing.

[0010] Furthermore, the two ends of the tension spring are configured in a hook shape.

[0011] Furthermore, the limiting component includes a limiting card body and a limiting port disposed on the limiting card body.

[0012] Furthermore, the limiting port is arc-shaped, and its arc is on the same circle as the rotation trajectory of the connecting shaft.

[0013] Compared with existing technologies, the oven with a stable upward-opening door provided by this utility model has an oven body and an oven door connected by a flip-up connecting mechanism. The flip-up connecting mechanism includes a rotating component, a pulling component, and a limiting component. The oven door is rotatably mounted on the oven body via the rotating component. The pulling component can tighten the oven door from different directions when it is closed or opened, ensuring the oven door remains stably open or closed. Since the oven door opening and closing is mainly maintained by the pulling component, specifically by the elasticity of the pulling spring, the stability of the oven door when open and the sealing when closed can be guaranteed simply by periodically replacing the pulling spring or according to the usage condition of the oven door. Compared to oven doors that flip left or right or downward, the upward-opening design of the oven door requires less space to flip. When the flip-up door is open, part of the door body overlaps with the top of the oven body, further reducing the oven's usable space requirements. Furthermore, the oven door and the oven body frame are no longer fixedly connected by hinges, and can be misaligned during the flipping process, making it easier to clean.

[0019] The specific embodiments of this utility model will be described in further detail below. It should be understood that the description of this utility model herein is not intended to limit the scope of protection of this utility model.

[0020] like Figures 1 to 5The diagram shown is a structural schematic of an oven with a stable upward-opening door provided by this utility model. The oven with a stable upward-opening door includes an oven body 10, an oven door 20 movably disposed on one side of the oven body 10, and two flip-connecting mechanisms 30 for connecting the oven body 10 and the oven door 20. It is conceivable that the oven with a stable upward-opening door should also include some other related functional components, such as installation components, assembly components, control modules, etc., all of which are prior art known to those skilled in the art and will not be described in detail here.

[0021] The oven body 10 includes a housing 11 and an outer shell 12 disposed on the outside of the housing 11. The housing 11 should also contain a heating plate, a baking rack, electrical connection components, and other related functional components. The outer shell 12 is fixedly disposed on the outside of the housing 11, mainly for protecting the housing 11 and providing heat insulation. The oven body 10 itself is prior art and will not be described in detail here.

[0022] The oven door 20 is located on the opening side of the oven body 10. It includes a door body 21 fixedly connected to the flip connection mechanism 30, a handle 22 disposed on the door body 21, a temperature display 23 disposed on the door body 21, and two connecting brackets 24 symmetrically disposed on both sides of the door body 21.

[0023] The door 21 can be a square structure, and its size can be set according to the size of the oven body 10.

[0024] The handle 22 is positioned horizontally on the side of the door 21 facing the ground to facilitate the flipping of the door 21.

[0025] The temperature display 23 is fixedly installed on the door 21 and electrically connected to the oven's control module to display the oven's baking temperature.

[0026] The connecting brackets 24 are symmetrically arranged on both sides of the door 21, and are located approximately one-third of the way from the top of the oven body 10, thus making it easier to seal the door 21 under gravity after it is closed. One side of the connecting bracket 24 is fixedly connected to the door 21, and the other side is fixedly connected to the flip-up connecting mechanism 30, thereby movably connecting the door 21 to the flip-up connecting mechanism 30. The oven door 20 itself is prior art and will not be described in detail here.

[0027] Two flip-connecting mechanisms 30 rotatably connect the oven door 20 to the oven body 10. The two flip-connecting mechanisms 30 are respectively disposed on the inner and outer sides of the oven body 11, corresponding to the connecting bracket 24. Each flip-connecting mechanism 30 includes a rotating component 31 fixedly connected to the oven door 20, a pulling component 32 connected to the rotating component 31, and a limiting member 33 located on one side of the rotating component 31.

[0028] like Figure 3 As shown, the rotating assembly 31 includes a support cylinder 311 fixedly mounted on the housing 11, a rotating shaft 312 passing through the support cylinder 311, and a traction connection assembly 313 mounted at one end of the rotating shaft 312.

[0029] The support cylinder 311 is fixedly mounted on the housing 11, and its diameter is adapted to the diameter of the rotating shaft 312 to support the rotating shaft 312.

[0030] The rotating shaft 312 passes through the support cylinder 311, with one end fixedly connected to the connecting bracket 24 and the other end fixedly connected to the tension connecting assembly 313. When the rotating shaft 312 is connected to the connecting bracket 24, at least one gasket can be provided on each side of the connecting bracket 24 to ensure a reliable connection between the connecting bracket 24 and the rotating shaft 312 and prevent loosening.

[0031] The tension connection assembly 313 is fixedly disposed at the end of the rotating shaft 312 away from the connecting bracket 24, and is used to connect the rotating assembly 31 and the tension assembly 32. The tension connection assembly 313 includes a connector body 3131 fixedly connected to the rotating shaft 312, and a connecting shaft 3132 fixedly disposed on the connector body 313. The connector body 3131 may have an "L" shaped structure, with one end fixedly connected to the rotating shaft 312. Similarly, gaskets may be provided on both sides where the connector body 3131 connects to the rotating shaft 312 to make the connection more stable. The connecting shaft 3132 is located at the end of the connector body 3131 away from the rotating shaft 312, and its axial direction is parallel to the axial direction of the rotating shaft 312. A limiting annular groove 3133 is also provided at the end of the connecting shaft 3132 away from the housing 11. When the rotating assembly 31 is connected to the pulling assembly 32, one end of the pulling spring 323 of the pulling assembly 32 is sleeved on the limiting ring groove 3133. The two side walls of the limiting ring groove 3133 can restrict the position of the pulling spring 323, preventing the pulling spring 323 from falling off or sliding off the connecting shaft 3132 during use.

[0032] The traction assembly 32 includes a mounting plate 321 fixedly disposed on one side of the housing 11, a spring mounting member 322 fixedly disposed on the mounting plate 321, and a traction spring 323 connected to the spring mounting member 322.

[0033] The mounting plate 321 is fixedly mounted on the housing 11 with its extension direction perpendicular to the vertical direction, and is located below the support cylinder 311.

[0034] The spring mounting component 322 is fixedly mounted vertically on the mounting plate 321, with its central axis perpendicular to and intersecting the central axis of the rotation shaft 312. The end of the spring mounting component 322 facing the rotation assembly 31 is arranged in a ring shape for mounting the tension spring 323.

[0035] The tension spring 323 is hook-shaped at both ends, with one end threaded onto the spring mounting member 322 and the other end fitted into the limiting ring groove 3133. The tension spring 323 is used to pull on the rotating assembly 31, meaning it is always in a stretched state, thus ensuring the oven door 20 remains stably open or closed. Specifically, when the oven door 20 is closed, the tension spring 323... Figure 2For reference, the rotating assembly 31 rotates clockwise towards the extending direction of the spring mounting member 322, causing the connecting body 3131 to tilt towards the oven door 20. The tension spring 323 then tilts towards the oven door 20, meaning the tension direction of the tension spring 323 forms an angle with the extending direction of the spring mounting member 322. At this time, the elastic force of the tension spring 323 exerts an oblique pull on the oven door 20, thus keeping the oven door 20 tightly closed. When the oven door 20 abuts against the housing 11, the rotating shaft 312 cannot rotate, thus preventing the rotating assembly 31 from rotating, achieving the function of limiting the main rotating assembly 31. Simultaneously, due to the continuous traction of the tension spring 323, the oven door 20 is tightly pressed against the housing 11, thereby improving the sealing effect.

[0036] by Figure 2 For reference, when it is necessary to open the oven door 20, grasp the handle 22 and pull the oven door 20 towards the flip-up connecting mechanism 30, causing the oven door 20 to flip towards one side of the flip-up connecting mechanism 30 until the oven door 20 is fully open. At this time, the rotating component 31 rotates in the opposite direction to the extension direction of the spring mounting member 322, i.e., counterclockwise. The tension spring 323 also tilts towards the side of the oven body 20 opposite to its opening, i.e., the direction of the tension force of the tension spring 323 also has an angle with the extension direction of the spring mounting member 322. When the tension spring 323 is tilted, its tension on the oven door 20 can be decomposed into vertical and horizontal directions. Its vertical tension pulls down on one side of the oven door 20, thereby keeping the oven door 20 in the open state, i.e., parallel to one side of the top of the oven body 10. After use, pull down the oven door 20 to return it to the closed state. It is conceivable that the tension value is the largest when the direction of the tension spring 323 coincides with the extension direction of the spring mounting member 322, and the tension value is smaller when there is an angle between the direction of the tension spring 323 and the extension direction of the spring mounting member. Therefore, the oven door 20 will not rotate by itself without the action of external force, thereby maintaining the open or closed state.

[0037] The limiting member 33 is used to restrict the rotation angle of the pulling connector 313 when the rotating assembly 31 rotates counterclockwise, i.e., when the oven door 20 opens, thereby ensuring the stability of the oven door 20 when it opens. The limiting member 33 includes a limiting card body 331 and a limiting opening 332 disposed on the limiting card body 331. The limiting card body 331 is fixedly installed vertically on the housing 11. The limiting opening 332 is located on the side of the limiting card body 331 facing the rotating assembly 31, and its size is adapted to the diameter of the connecting shaft 3132 facing the housing 11. The limiting opening 332 is arc-shaped, and its arc is on the same circle as the rotation trajectory of the connecting shaft 3132. Figure 2 For reference, when the rotating assembly 31 rotates counterclockwise, the connecting shaft 3132 facing the housing 11 will slide into the limiting opening 332 to maintain the stability of the oven door 20 when it is open. When the oven door 20 is in the open state, the tension spring 323 is still in the traction tension state, that is, the tension spring 323 still provides tension, so that the oven door 20 is in the open state with the cooperation of the limiting member 33, and an external force is required to close the oven door 20 again.

[0038] Compared with the prior art, the oven with a stable upward-opening door provided by this utility model has an oven body 10 and an oven door 20 connected by a flip-up connecting mechanism 30. The flip-up connecting mechanism 30 includes a rotating component 31, a pulling component 32, and a limiting member 33. The oven door 20 is rotatably mounted on the oven body 10 via the rotating component 31. The pulling component 32 can tighten the oven door 20 from different directions when it is closed or opened, ensuring that the oven door 20 can be stably maintained in either open or closed state. Since the opening and closing of the oven door 20 is mainly maintained by the pulling component 32, specifically by the elasticity of the pulling spring 323 within the pulling component 32, the stability of the oven door 20 when open and its sealing performance when closed can be ensured simply by periodically replacing the pulling spring 323 or according to the usage condition of the oven door 20. Compared to oven doors that flip left or right or downward, the upward-opening design of the oven door 20 requires less space to flip. When the flip door 20 is opened, part of its door body 21 overlaps with the top of the oven body 10, further reducing the space required for the oven. Furthermore, the oven door 20 and the oven body 10 are no longer fixedly connected by hinges; they can be misaligned during the flipping process, facilitating cleaning.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
