Description

Technical Field

[0001] This utility model relates to the field of oven technology, and in particular to a control structure for a large-angle opening and closing oven door and an oven. Background Technology

[0002] Ovens, as a common cooking appliance, are widely used in home and commercial kitchens. Their main function is to generate heat through heating elements to bake and roast food. In current technology, oven doors typically use traditional hinges for control, which, due to structural limitations, restricts the opening angle of the oven door to between 90° and 120°. This limited angle requires users to frequently adjust their hand positions when handling large baking trays or multi-tiered baking racks, and can even cause food to tip over due to insufficient space. Especially after baking, the confined operating space increases the risk of burns, particularly in the high-temperature environment.

[0003] Therefore, it is necessary to improve the existing oven door control structure to overcome the shortcomings of the existing technology. Utility Model Content

[0004] To overcome the problems existing in related technologies, one of the objectives of this utility model is to provide a large-angle opening and closing oven door control structure. This structure enables the oven door to open at a large angle, thereby making the oven more convenient to use and improving the user experience.

[0005] A control structure for a large-angle opening and closing cabinet door includes:

[0006] A substrate, wherein a groove is provided on the substrate, and the length direction of the groove is along the width direction of the substrate;

[0007] A slidable slide plate is provided on the slide groove, and a connecting rod assembly is provided on the slide plate. One end of the connecting rod assembly is hinged to the slide plate, and the other end is hinged to the door.

[0008] The door is located on one side of the substrate, and the bottom of the door is hinged to the bottom of the substrate.

[0009] In a preferred embodiment of this utility model, two substrates are arranged in parallel, each substrate is provided with a sliding groove, and each sliding groove is provided with a sliding plate;

[0010] A support rod is provided between the two slide plates, and the two opposite ends of the support rod are respectively fixed to the two opposite slide plates.

[0011] In a preferred embodiment of this invention, the linkage assembly includes a first rod body having a first end and a second end disposed opposite to each other. The first end of the first rod body is hinged to the middle or end of the slide plate, and the second end of the first rod body is hinged to the door.

[0012] In a preferred embodiment of this utility model, the slide plate includes a first plate and a second plate, both of which are disposed on the slide groove along the length of the slide groove; one end of the first plate is fixed to one end of the slide groove, and the opposite end is hinged to one end of the second plate via a connecting shaft; the end of the second plate away from the first plate is slidably disposed on the slide groove.

[0013] One end of the connecting rod assembly is hinged to the connecting shaft, and the other end is hinged to the door.

[0014] In a preferred embodiment of this invention, a damping element is provided at the hinge joint between the door and the substrate.

[0015] The second objective of this utility model is to provide an oven, including a main body, on which a door control structure with a large opening angle as described above is provided;

[0016] The door is located on one side of the main body.

[0017] In a preferred embodiment of this utility model, the main body includes an inner liner and an outer cover, the outer cover being disposed around the inner liner, and a heating rod being disposed inside the inner liner;

[0018] The substrate is disposed on the side wall of the inner liner, and the plane of the substrate is perpendicular to the plane of the door when it is closed.

[0019] In a preferred embodiment of this utility model, the inner liner is provided with a front side plate, the front side plate is perpendicular to the base plate, the front side plate is provided with a clearance opening, and the connecting rod assembly passes through the clearance opening and is hinged to the door.

[0020] The beneficial effects of this utility model are as follows:

[0021] This utility model provides a control structure for a large-angle opening oven door. The structure includes a base plate with a sliding groove along its length. A slidable slide plate is mounted on the groove, and a connecting rod assembly is mounted on the slide plate. One end of the connecting rod assembly is hinged to the slide plate, and the other end is hinged to the oven door. The oven door is located on one side of the base plate, and its bottom is hinged to the bottom of the base plate. This control structure can be used to control the opening and closing of an oven door. When the door needs to be opened, the user pulls it outward, causing the door to rotate around its hinge point with the base plate. During this rotation, the connecting rod assembly drives the slide plate to slide within the groove to the edge of the base plate. The door then continues to rotate, further rotating the connecting rod assembly, thus achieving a large-angle opening. When the door needs to be closed, the user pushes it, causing it to rotate in the opposite direction around the hinge point. The connecting rod assembly drives the slide plate to slide in the opposite direction within the groove until the door is completely closed. This control structure allows the oven door to open to over 180°, facilitating the placement of large utensils such as baking trays and molds, or enabling thorough cleaning of the oven interior. Furthermore, this control structure is adaptable to ovens of different sizes; standardized production can be achieved simply by adjusting the base plate size and connecting rod length, reducing the design and modification costs of oven manufacturing.

[0022] This application also provides an oven with a door control structure that allows for a large opening angle, which is convenient to use and can improve the user experience. Attached Figure Description

[0033] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0034] Ovens, as a common cooking appliance, are widely used in home and commercial kitchens. Their main function is to generate heat through heating elements to bake and roast food. In current technology, oven doors typically use traditional hinges for control, which, due to structural limitations, restricts the opening angle of the oven door to between 90° and 120°. This limited angle requires users to frequently adjust their hand positions when handling large baking trays or multi-tiered baking racks, and can even cause food to tip over due to insufficient space. Especially after baking, the confined operating space increases the risk of burns, particularly in the high-temperature environment.

[0035] Based on this, this application provides a control structure for a large-angle opening and closing of a cabinet door.

[0036] Example 1

[0037] like Figures 1-6 As shown in the figure, the control structure for a large-angle opening and closing cabinet door 4 provided in this embodiment includes:

[0038] A substrate 1, on which a groove 11 is provided, the length direction of the groove 11 being arranged along the width direction of the substrate 1;

[0039] The slide 11 is provided with a slidable slide plate 2, and the slide plate 2 is provided with a connecting rod assembly 3. One end of the connecting rod assembly 3 is hinged to the slide plate 2, and the other end is hinged to the door 4.

[0040] The door 4 is disposed on one side of the substrate 1, and the bottom of the door 4 is hinged to the bottom of the substrate 1.

[0041] Specifically, the slide groove 11 extends through the substrate 1 along its thickness. The sliding plate 2 of this application is hinged to a connecting rod assembly 3, which consists of two rotatably connected rods: one end of the first connecting rod is hinged to one end of the sliding plate 2 via a pin, and the other end is hinged to the middle of the second connecting rod; the other end of the second connecting rod is hinged to the top outer side of the door 4 via a pin. The bottom of the door 4 is hinged to the bottom of the substrate 1 via a hinge, forming a rotatable fulcrum.

[0042] The aforementioned control structure for a large-angle opening oven door 4 includes a base plate 1 with a slide groove 11. The length of the slide groove 11 is aligned with the width of the base plate 1. A slidable slide plate 2 is mounted on the slide groove 11, and a connecting rod assembly 3 is mounted on the slide plate 2. One end of the connecting rod assembly 3 is hinged to the slide plate 2, and the other end is hinged to the oven door 4. The oven door 4 is located on one side of the base plate 1, and its bottom is hinged to the bottom of the base plate 1. This control structure can be used to control the opening and closing of the oven door 4. When the oven door 4 needs to be opened, the user pulls the oven door 4 outward, causing it to rotate around the hinge point between its bottom and the base plate 1. During the rotation of the oven door 4, the connecting rod assembly 3 drives the slide plate 2 to slide within the slide groove 11 to the edge of the base plate 1. Then, the oven door 4 continues to rotate and open, driving the connecting rod assembly 3 to rotate, thereby achieving a large-angle opening of the door panel. When it is necessary to close the door 4, the user pushes the door 4, and the door 4 rotates in the opposite direction around the hinge point. The connecting rod assembly 3 drives the slide plate 2 to slide in the opposite direction in the slide groove 11 until the door 4 is completely closed.

[0043] Furthermore, two substrates 1 are arranged in parallel, each substrate 1 is provided with a groove 11, and each groove 11 is provided with a sliding plate 2;

[0044] A support rod 5 is provided between the two slide plates 2, and the two opposite ends of the support rod 5 are respectively fixed on the two opposite slide plates 2.

[0045] When the two substrates 1 are arranged in parallel, the left and right substrates 1 are rigidly connected by support rods 5 to form a symmetrical support structure. When the door 4 is opened, the two sliding plates 2 slide synchronously in the slide grooves 11. The support rods 5 can prevent the sliding plates 2 from being misaligned or tilted due to uneven force. The structure of the two substrates 1 forms a "rigid frame" through the support rods 5, which evenly distributes the weight of the door 4 to the two substrates 1, so that the overall structure remains stable when opened at a large angle, avoiding shaking or deformation.

[0046] The dual-base plate design ensures that the force is evenly distributed on both sides of the door 4, reducing local wear caused by single-point support. During long-term use, it is less likely to cause the slide plate 2 to jam due to excessive force on one side, ensuring smooth opening and closing operation and reducing noise caused by component wear.

[0047] In one specific embodiment, the linkage assembly 3 includes a first rod having a first end and a second end disposed opposite to each other. The first end of the first rod is hinged to the middle or end of the slide plate 2, and the second end of the first rod is hinged to the door 4.

[0048] The first rod is a straight metal rod, the length of which is set according to the opening angle requirements of the box door 4, and hinge holes are machined at both ends.

[0049] The first end of the first rod is hinged to the middle of the slide plate 2 via a pin (or the end of the slide plate 2 is selected according to the spatial layout). The axis of the pin is perpendicular to the plane of the base plate 1, so that the first rod can rotate in the vertical plane around the hinge point.

[0050] The second end of the first rod is hinged to the upper outer side of the door 4 via a pin. The hinge point is located at the center of the width direction of the door 4 (or symmetrically distributed on both sides) to ensure balanced force distribution.

[0051] In this embodiment, when the door 4 rotates around the bottom hinge, the first rod rotates synchronously with the door 4, and its first end drives the slide plate 2 to slide laterally in the slide groove 11. Through the linkage of "rod rotation + slide plate 2 sliding", the door 4 can be opened at a large angle.

[0052] In another embodiment, the slide plate 2 includes a first plate body 21 and a second plate body 22, both of which are disposed on the slide groove 11 along the length direction of the slide groove 11; one end of the first plate body 21 is fixed to one end of the slide groove 11, and the opposite end is hinged to one end of the second plate body 22 via a connecting shaft 23; the end of the second plate body 22 away from the first plate body 21 is slidably disposed on the slide groove 11;

[0053] One end of the connecting rod assembly 3 is hinged to the connecting shaft 23, and the other end is hinged to the door 4.

[0054] One end of the connecting rod assembly 3 is hinged to the connecting shaft 23 between the first plate 21 and the second plate 22, and the other end is hinged to the middle of the outer side of the door 4 via a pin. When the door 4 rotates around the bottom hinge, the connecting rod assembly 3 drives the connecting shaft 23 to move. At this time: if the door 4 is open, the second plate 22 rotates around the connecting shaft 23 while its free end slides backward in the slide groove 11, and the first plate 21 and the second plate 22 form an angle. The overall length of the slide plate 2 changes dynamically with the opening angle of the door 4. If the door 4 is closed, the second plate 22 returns to its original position around the shaft under the action of the connecting rod tension, and its free end slides forward along the slide groove 11 until the first plate 21 and the second plate 22 are approximately collinear.

[0055] In this embodiment, the split sliding plate 2 is connected by a hinge, so that the second plate 22 can swing as the door 4 rotates. When the door 4 is opened to different angles, the connecting shaft 23 drives the second plate 22 to slide in the slide groove 11, and its hinge point can adaptively adjust the force direction of the connecting rod assembly 3.

[0056] Furthermore, a damping element is provided at the hinge joint between the door 4 and the base plate 1.

[0057] The damping component can be in the form of a hydraulic damper, a silicone damping pad, or a friction damping sheet, and is installed at the hinge or pin shaft at the bottom of the door 4 that is hinged to the base plate 1. Taking a hydraulic damper as an example, its cylinder is fixed to the base plate 1, and the piston rod is hinged to the door 4. When the door 4 is opened or closed, the hydraulic oil inside the damper generates resistance through the throttling orifice, forming a buffer torque.

[0058] The damping element provides controllable resistance to prevent the door 4 from falling freely or springing open rapidly due to gravity. For example, after the user opens the door 4 to any angle and releases it, the damping force can keep the door 4 stationary, preventing the door 4 from suddenly falling back and pinching the hand when opened at a large angle.

[0059] Example 2

[0060] like Figures 1-8 As shown, this embodiment provides an oven, including a main body 100, on which a large-angle opening and closing oven door 4 control structure as described above is provided;

[0061] The door 4 is located on one side of the main body 100.

[0062] Specifically, the main body 100 includes an inner liner 110 and an outer cover 120. The outer cover 120 covers the periphery of the inner liner 110, and a heating rod is disposed inside the inner liner 110.

[0063] The substrate 1 is disposed on the side wall of the inner liner 110, and the plane of the substrate 1 is perpendicular to the plane of the door 4 when it is closed.

[0064] Furthermore, the inner liner 110 is provided with a front side plate 130, which is perpendicular to the base plate 1. The front side plate 130 is provided with a clearance opening 1301, and the connecting rod assembly 3 passes through the clearance opening 1301 and is hinged to the door 4.

[0065] The clearance opening 1301 facilitates the movement of the connecting rod and prevents interference between the front side plate 130 and the connecting rod assembly 3. The heating rod can evenly heat the food inside the inner liner 110, while the outer cover 120 provides heat insulation and protection. The vertical arrangement of the base plate 1 and the oven door 4, combined with the connection method of the connecting rod assembly 3 passing through the clearance opening 1301, ensures that the oven door 4 can open and close at a large angle, and also eliminates the obstruction of the connecting rod movement by the front side plate 130 through the clearance opening 1301, making the opening and closing of the oven door 4 more flexible. At the same time, it ensures that the inner liner 110 has a compact structure, does not affect the heating function, and improves the convenience and reliability of the oven.

[0066] This control structure allows the oven door to open at four different angles, making it easier for users to operate and clean the inside of the oven, thereby improving the user experience.
