Description

Technical Field

[0001] This utility model relates to the field of oven technology, and in particular to a detachable telescopic door hinge and an oven. Background Technology

[0002] As a commonly used heating and cooking appliance, the stability of the connection between the oven door and the oven body, as well as the safety of its use, are crucial. The door hinge is the core component that enables the door to open and close. Currently, most oven door hinges are fixed structures, forming a rigid connection with the door and oven body through welding, fastening bolts, etc., to meet the structural strength requirements of the oven under high-temperature operating conditions.

[0003] However, during long-term use, oven doors easily accumulate grease, food residue, and dust in the gaps between the hinges and the oven body. This is because ovens produce high-temperature steam and grease during cooking, and these substances gradually seep into the gaps between the hinges as the door opens and closes, easily solidifying into stubborn stains under high temperatures. Due to the fixed hinge structure, the oven door cannot be easily separated from the hinges, making these gaps difficult to clean. Even with specialized cleaners and tools, it is difficult for users to thoroughly clean these gaps. Long-term accumulation of stains not only emits unpleasant odors, affecting the hygiene of the kitchen environment, but may also corrode the metal components of the hinges due to the corrosiveness of the grease, causing wear and jamming, thus affecting the normal opening and closing of the door, and even posing a safety hazard of the door loosening or falling off.

[0004] Therefore, it is necessary to improve the installation method of the motor in existing cabinet air conditioners in order to overcome the defects of the existing technology. Utility Model Content

[0005] To overcome the problems existing in related technologies, one of the objectives of this utility model is to provide a detachable telescopic door hinge. This detachable telescopic door hinge is applied to the door panel of an oven and can be extended and retracted through the connecting shaft to allow the door panel to be quickly disassembled, thereby making the gap between the door panel and the oven support easy to clean and helping to extend the service life of the oven.

[0006] A detachable telescopic door hinge includes a mounting base plate, a control plate is disposed on the mounting base plate, the control plate is hinged to the mounting base plate via a rotating shaft, and a damping element is disposed on the connecting shaft;

[0007] A plurality of connecting shafts are provided, each of which is located on one side of the mounting base plate; each connecting shaft includes a connecting end and a free end, the free end being snapped onto the control plate, such that the rotation of the control plate allows the free end to move along the axial direction of the connecting shaft.

[0008] In a preferred embodiment of this invention, the axis of each connecting shaft is parallel to the plane of the mounting substrate, and the free ends of at least two connecting shafts are arranged opposite to each other.

[0009] In a preferred embodiment of this utility model, three connecting shafts are provided, two of which are provided on the first side of the mounting base plate and the other connecting shaft is provided on the second side of the mounting base plate.

[0010] The first and second sides of the mounting substrate are symmetrical about the axis of the mounting substrate.

[0011] In a preferred embodiment of this invention, the control board is provided with an oblong connecting hole, and the connecting end of the connecting shaft is engaged in the connecting hole.

[0012] In a preferred embodiment of this utility model, support side plates are respectively provided on opposite sides of the mounting substrate, and the support side plates are perpendicular to the mounting substrate.

[0013] The support side plate is provided with a first guide hole, and the connecting end of the connecting shaft passes through the first guide hole and is engaged with the control board.

[0014] In a preferred embodiment of this invention, a guide member is further included. The guide member is disposed around the mounting base plate and has a second guide hole. The free end of the connecting shaft passes through the second guide hole.

[0015] In a preferred embodiment of this invention, the damping element is a torsion spring, which is disposed around the rotating shaft, with one end of the torsion spring abutting against the mounting base plate and the other end abutting against the control plate.

[0016] The second objective of this utility model is to provide an oven, including a cabinet and a door panel, wherein the door panel is provided with a detachable telescopic door hinge as described above, and the door panel is hinged to the cabinet via the telescopic door hinge.

[0017] The beneficial effects of this utility model are as follows:

[0018] This utility model provides a detachable telescopic door hinge, which includes a mounting base and connecting shafts. A control plate is mounted on the mounting base and is hinged to the mounting base via a rotating shaft. A damping element is provided on the connecting shafts. Several connecting shafts are provided, each located on one side of the mounting base. Each connecting shaft includes a connecting end and a free end, the free end of which is engaged with the control plate, allowing the free end to move along the axial direction of the connecting shaft when the control plate rotates. When this detachable telescopic door hinge is used in an oven, the mounting base is fixedly mounted on the side of the oven door panel, and the oven body has through holes corresponding to the positions of the connecting shafts. When the door panel needs to be installed, external force is applied to rotate the control plate. Because the free end is engaged with the control plate, the rotation of the control plate causes the free end to move along the axial direction of the connecting shaft, shortening the overall length of the connecting shaft. Align the free end of the connecting shaft with the through hole on the oven bracket, remove external force to allow the control plate to reset under the action of the damping component, and drive the free end of the connecting shaft through the through hole and extend a certain length to secure the door panel to the oven. When the door panel needs to be removed for cleaning, simply rotate the control plate to move the free end of the connecting shaft along the axial direction and disengage it from the through hole on the oven bracket, allowing the door panel to be easily removed. This door hinge, through its telescopic structure, allows users to quickly and easily remove the oven door panel, completely exposing the gap between the door panel and the oven bracket, eliminating cleaning dead zones. Users can easily and thoroughly clean grease, food residue, and other contaminants from the gap, effectively preventing odors and bacterial growth caused by accumulated dirt, greatly improving the hygiene of the oven. The disassembly and installation of this telescopic door hinge can be achieved simply by rotating the control plate; no professional tools or personnel are required, and ordinary users can easily complete the operation.

[0019] This application also provides an oven including the aforementioned detachable telescopic door hinge. This oven is easy to use, and the door panel is easy to disassemble, which helps to save cleaning time in the later use. It makes it easier for users to thoroughly clean the gaps in the door panel, avoids corrosion and wear of the door hinge and related oven parts by oil stains and other stains, reduces the failure problems of the door hinge due to the accumulation of stains, and thus helps to extend the overall service life of the oven.

[0027] 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.

[0028] During long-term use, oven doors easily accumulate grease, food residue, and dust in the gaps between the door panel, hinges, and the oven body. This is because ovens generate high-temperature steam and grease during cooking, and these substances gradually seep into the gaps between the hinges as the door panel opens and closes, easily solidifying into stubborn stains under high temperatures. Due to the structural limitations of fixed hinges, oven doors cannot be easily separated from them, making these gaps difficult to clean. Even with specialized cleaning agents and tools, it is difficult for users to thoroughly clean the gaps. Long-term accumulation of stains not only emits unpleasant odors, affecting the hygiene of the kitchen environment, but may also corrode the metal components of the hinges due to the corrosiveness of the grease, leading to wear and jamming of the hinges, thus affecting the normal opening and closing of the door panel, and even posing a safety hazard of the door panel loosening or falling off. Therefore, this application provides a detachable telescopic door hinge.

[0029] Example 1

[0030] like Figures 1-5 As shown in the figure, this embodiment provides a detachable telescopic door hinge, which includes a mounting base plate 1 and a connecting shaft 3. A control plate 2 is disposed on the mounting base plate 1, and the control plate 2 is hinged to the mounting base plate 1 via a rotating shaft 5. A damping element is disposed on the connecting shaft 3. Several connecting shafts 3 are provided, and each connecting shaft 3 is disposed on one side of the mounting base plate 1. Each connecting shaft 3 includes a connecting end 32 and a free end 31. The free end 31 is engaged with the control plate 2, so that the rotation of the control plate 2 allows the free end 31 to move along the axial direction of the connecting shaft 3.

[0031] Specifically, both the mounting base plate 1 and the control plate 2 are made of high-temperature resistant metal. The mounting base plate 1 is fixedly mounted on the oven door panel 110. A rotating shaft 5 is provided on the mounting base plate 1, and the control plate 2 is hinged to the rotating shaft 5, thereby enabling the control plate 2 to rotate on the mounting base plate 1.

[0032] Each connecting shaft 3 is a cylindrical structure, also made of high-temperature resistant metal. The connecting end 32 of the connecting shaft 3 engages with the control plate 2. The control plate 2 has a corresponding slot for each connecting end 32 of the connecting shaft 3, and the connecting end 32 of the connecting shaft 3 engages within the slot, achieving a locking fit between the connecting shaft 3 and the control plate 2. It should be noted that during installation, it is necessary to ensure that the connecting end 32 of the connecting shaft 3 does not detach from the slot when the control plate 2 rotates.

[0033] The control board 2 is a plate-shaped structure that matches the mounting base plate 1. It is also made of high-temperature resistant material. It is hinged to the side of the mounting base plate 1 away from the connecting shaft 3 via a rotating shaft 5. The axis of the rotating shaft 5 is perpendicular to the axis of the connecting shaft 3, allowing the control board 2 to rotate freely around the rotating shaft 5. The control board 2 has a slot that matches the annular groove at the position of the free end 31 of each connecting shaft 3. The free end 31 is engaged in the slot through the annular groove, realizing the engagement between the connecting shaft 3 and the control board 2.

[0034] The damping element is a torsion spring, which is disposed around the rotating shaft 5, with one end of the torsion spring abutting against the mounting base plate 1 and the other end abutting against the control plate 2.

[0035] The torsion spring generates damping force through its own elastic deformation. Its damping characteristics are stable, and it can provide corresponding restoring force according to the rotation angle of the control plate 2. When the user rotates the control plate 2 to extend or retract the connecting shaft 3, the torsion spring will accumulate elastic potential energy due to deformation. After the external force is removed, the elastic potential energy of the torsion spring is released, causing the control plate 2 to automatically reset. This ensures that the free end 31 of the connecting shaft 3 can accurately engage or disengage from the through hole of the oven body, ensuring the reliability of the door panel 110 installation and disassembly process, and avoiding the problem of the control plate 2 shaking randomly or failing to reset properly due to insufficient damping.

[0036] When this detachable telescopic door hinge is used on an oven, the mounting base 1 is fixedly installed on the side of the oven door panel 110. A through hole, matching the connecting shaft 3, is provided on the oven body at the position corresponding to the connecting shaft 3. When the door panel 110 needs to be installed, external force is applied to rotate the control plate 2. Since the free end 31 is engaged with the control plate 2, the rotation of the control plate 2 will cause the free end 31 to move along the axial direction of the connecting shaft 3, shortening the overall length of the connecting shaft 3. Aligning the free end 31 of the connecting shaft 3 with the through hole on the oven bracket, removing the external force allows the control plate 2 to reset under the action of the damping element, causing the free end 31 of the connecting shaft 3 to pass through the through hole and extend a certain length, thus achieving the installation and fixation of the door panel 110 to the oven. When the door panel 110 needs to be removed for cleaning, simply rotate the control plate 2 to move the free end 31 of the connecting shaft 3 along the axial direction and disengage it from the through hole on the oven bracket, allowing the door panel 110 to be easily removed. The door hinge, via a telescopic structure connecting shaft 3, allows users to quickly and easily remove the oven door panel 110, completely exposing the gap between the door panel 110 and the oven support, eliminating cleaning dead spots. Users can easily and thoroughly clean grease, food residue, and other contaminants from the gap, effectively preventing odors and bacterial growth caused by accumulated dirt, greatly improving the hygiene of the oven. The disassembly and installation of this telescopic door hinge can be achieved simply by rotating the control panel 2, requiring no special tools or professionals; ordinary users can easily complete the operation.

[0037] In one specific embodiment, the axis of each connecting shaft 3 is parallel to the plane of the mounting base plate 1, and the free ends 31 of at least two connecting shafts 3 are arranged opposite to each other.

[0038] The axis of each connecting shaft 3 is parallel to the plane of the mounting base plate 1, and the free ends 31 of at least two connecting shafts 3 are set opposite to each other. This structural design makes the connection points between the connecting shafts 3 and the oven body more reasonably distributed, and can fix the door panel 110 from different directions, greatly enhancing the stability of the connection between the door panel 110 and the oven, and reducing the shaking of the door panel 110 during use.

[0039] In another specific embodiment, three connecting shafts 3 are provided, two of which are provided on the first side of the mounting base plate 1, and the other connecting shaft 3 is provided on the second side of the mounting base plate 1.

[0040] The first side and the second side of the mounting substrate 1 are symmetrical about the axis of the mounting substrate 1.

[0041] Compared to two connecting shafts, the use of three connecting shafts 3 increases the number of connection points between the door panel 110 and the oven body. Furthermore, with two connecting shafts concentrated on the first side and one on the centrally symmetrical second side, this distribution allows for more comprehensive fixation of the door panel 110, resulting in more even force distribution during opening, closing, and use. This effectively reduces the wobbling amplitude of the door panel 110, further enhancing the stability of the connection and lowering the risk of the door panel 110 becoming loose.

[0042] Furthermore, the control board 2 is provided with a waist-shaped connecting hole 21, and the connecting end 32 of the connecting shaft 3 is engaged in the connecting hole 21.

[0043] The waist-shaped connecting hole 21 has a certain length margin. When the control plate 2 drives the free end 31 of the connecting shaft 3 to move along the axial direction, the connecting end 32 of the connecting shaft 3 can slide adaptively along the length direction of the hole in the waist-shaped connecting hole 21. This reduces the stress caused by rigid constraints during the extension and retraction of the connecting shaft 3, making the movement of the connecting shaft 3 smoother and avoiding jamming. This ensures the smoothness of the disassembly and installation of the door panel 110.

[0044] In a preferred embodiment, support side plates 11 are respectively provided on opposite sides of the mounting base plate 1, and the support side plates 11 are perpendicular to the mounting base plate 1.

[0045] The support side plate 11 is provided with a first guide hole, and the connecting end 32 of the connecting shaft 3 passes through the first guide hole and is engaged with the control plate 2.

[0046] Furthermore, it also includes a guide member 4, which is disposed on the periphery of the mounting base plate 1. The guide member 4 is provided with a second guide hole, and the free end 31 of the connecting shaft 3 passes through the second guide hole.

[0047] The first guide hole on the supporting side plate 11 and the second guide hole on the guide member 4 form a double guide structure, which plays a precise limiting and guiding role in the telescopic movement of the connecting shaft 3. When the connecting shaft 3 moves along the axial direction, its connecting end 32 is constrained by the first guide hole and its free end 31 is constrained by the second guide hole. This can effectively prevent the connecting shaft 3 from deviating or shaking due to uneven force, ensuring that the connecting shaft 3 always moves stably along the preset axis, and further improving the smoothness of the disassembly and installation process of the door panel 110.

[0048] In a preferred embodiment, a spring 33 is also provided on the connecting end 32 of any connecting shaft 3, and a limiting block 34 is provided on the connecting shaft 3 to limit the spring 33. The spring 33 plays a buffering role when the connecting end 32 is engaged with the through hole of the oven.

[0049] Example 2

[0050] like Figures 1-5 As shown, this embodiment provides an oven, including a housing 100 and a door panel 110. The door panel 110 is provided with a detachable telescopic door hinge as described above, and the door panel 110 is hinged to the housing 100 through the telescopic door hinge.

[0051] This oven is easy to use, and the door panel 110 is easy to disassemble, which saves cleaning time later. It allows users to thoroughly clean the gaps in the door panel 110, avoiding corrosion and wear of the door hinges and related oven parts by oil stains and other dirt. This reduces the failure problems of the door hinges due to the accumulation of dirt, thus helping to extend the overall service life of the oven.
