Description

Technical Field

[0001] This utility model relates to the field of microwave oven technology, and in particular to a microwave oven panel support and positioning reinforcement structure. Background Technology

[0002] like Figures 7-12 As shown, in existing microwave ovens with push-button controls, the panel assembly has a support rod positioning structure for mounting the support rod parts. The button parts are installed below the panel 101. Pressing the button 102 causes the support rod 103 to rotate by an angle, which pushes the door hook 105 on the door assembly 104, thereby opening the door assembly 104. When opening the microwave oven door assembly 104, simply pressing the button 102 opens the microwave oven door, allowing food to be placed or removed. In existing microwave ovens with push-button door opening, when the door opening button 102 is pressed, the support rod 103 engages with the relevant components... The microwave oven door opens by rotating around the pivot 106 and contacting the door hook 105 of the door assembly 104. The support rod 103 is generally composed of a rod body 107 and a connecting end 108. The rod body 107 is the main support and transmission part. It is usually long and has a certain length and rigidity to ensure that no obvious deformation occurs during the transmission of force. The connecting end 108 is used to connect with the microwave oven switch bracket and the door hook 105. The rod body 107 is connected to the button 102 that drives it to rotate. The pivot 106 is rotatably connected to the support rod positioning hole 109 on the panel 101.

[0003] The microwave oven support rod 103 is commonly made of flame-retardant material. This is because the support rod 103 may come into contact with live parts during operation. Using flame-retardant material can reduce the risk of fire caused by electrical faults and improve the safety of microwave oven use.

[0004] The commonly used microwave oven panel support structure with a strut positioning mechanism is prone to deformation and breakage around the strut positioning hole 109 on the microwave oven panel 101 due to frequent use of the microwave oven door opening button 102. This can lead to door opening failure. The strut positioning hole 109 on the panel 101 is continuously subjected to tensile and compressive stresses, which can cause material fatigue and breakage of the support parts. This can result in the inability to open the microwave oven door properly, leading to the risk of not being able to open the door after cooking, which seriously affects the customer's user experience.

[0005] Therefore, further improvements are necessary. Utility Model Content

[0006] The purpose of this utility model is to provide a microwave oven panel support and reinforcement structure that is simple in structure, reliable in support, has a long service life, smooth in opening, and highly practical, so as to overcome the shortcomings of the prior art.

[0007] A microwave oven panel support and reinforcement structure designed for this purpose includes a panel disposed on one side of the cavity and a support rod mounted on the panel. The panel is provided with a positioning support hole, and the support rod is provided with a support column. The support column is rotatably connected to the positioning support hole. The feature is that the support column is provided with a reinforcing rubber part, and reinforcing ribs are provided on both sides of the positioning support hole, and the reinforcing ribs are connected to the panel.

[0008] The panel has a clearance notch for avoiding the struts, and the reinforcing ribs are at least partially located on the clearance notch.

[0009] The panel is equipped with support blocks, positioning support holes are located on the support blocks, and reinforcing ribs are located on both sides of the support blocks.

[0010] Supporting connection parts are provided on both sides of the clearance gap. One end of the reinforcing rib is connected to the support block, and the other end of the reinforcing rib is connected to the supporting connection part.

[0011] The support block, reinforcing ribs, and support connection together form a triangular support structure.

[0012] The reinforcing ribs are installed at an angle, both vertically and horizontally, on the clearance gap.

[0013] The panel, reinforcing ribs, and positioning support holes are integrally molded.

[0014] One end of the support column extends into the clearance gap.

[0015] A button is mounted on the panel, and an actuating post is provided on the button. The actuating post abuts against the support rod. When the button is pressed, the actuating post acts on the support rod to make the support rod rotate.

[0016] An elastic element is installed between the button and the panel. When the button is released, it resets under the elastic force of the elastic element, and the support rod rotates to reset.

[0017] The microwave oven panel support and positioning reinforcement structure of this utility model has the following advantages:

[0018] 1. The support rod is installed and fixed on the microwave oven panel without any additional processing by the user. The support column of the support rod is reinforced with rubber, and the panel support rod positioning support is reinforced with ribs for reliable and firm support.

[0019] 2. Reinforcing ribs are set on both sides of the positioning support hole. The reinforcing ribs can improve the strength and rigidity of the panel in the support rod positioning area, prevent the positioning support hole from deforming or breaking due to frequent opening and closing of the door, ensure accurate positioning of the support rod, make the microwave oven door open and close smoothly and stably, and increase structural stability.

[0020] 3. The reinforcing ribs connecting the panel can distribute the force, distributing the force generated by the support rod during opening and closing to a larger panel area, avoiding excessive local stress on the positioning support holes, and extending the service life of the panel and support rod.

[0021] 4. Add clearance notches to the panel to prevent the support rod from interfering with the panel during operation (rotation). Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0035] See Figures 1-6 The microwave oven panel support and positioning reinforcement structure includes a panel 2 located on one side of the cavity 1 and a support rod 3 mounted on the panel 2. The panel 2 is provided with a positioning support hole 4, and the support rod 3 is provided with a support column 5. The support column 5 is rotatably connected to the positioning support hole 4. The support column 5 is provided with a reinforcing rubber part, and the upper and lower sides of the positioning support hole 4 are respectively provided with reinforcing ribs 6, which are connected to the panel 2.

[0036] The side of panel 2 is provided with a clearance notch 7 to avoid the support rod 3, and the reinforcing rib 6 is at least partially set on the clearance notch 7; the support column 5 is glued to increase strength, the panel side is glued to avoid the clearance notch 7, and the reinforcing rib 6 is added locally. The support rod 3 is installed to the support block 8. Pressing the button 10, the door opens smoothly and reliably; compared with the traditional panel and support rod structure used in microwave ovens, this structure is more reliable, firm and stable.

[0037] A support block 8 is provided on the panel 2, a positioning support hole 4 is provided on the support block 8, and reinforcing ribs 6 are respectively provided on the upper and lower sides of the support block 8.

[0038] Supporting connection parts 9 are provided on the upper and lower sides of the clearance gap 7, the lower end of the reinforcing rib 6 is connected to the supporting block 8, and the upper end of the reinforcing rib 6 is connected to the supporting connection part 9.

[0039] The support block 8, the reinforcing rib 6, and the support connection part 9 together form a triangular support structure. The triangular support structure can greatly increase the support strength, so that the strut 3 does not fall off or break when it is installed in the positioning support hole 4.

[0040] The reinforcing rib 6 is inclined vertically on the clearance notch 7, which can improve the supporting strength of the reinforcing rib 6.

[0041] Panel 2, reinforcing rib 6 and positioning support hole 4 (i.e. support block 8) are integrally injection molded. During the injection molding process, the reinforcing rib 6 is designed to be integrated with the panel body and the positioning support hole 4, so that they are seamlessly connected, with good integrity and strength, and can effectively transmit force and enhance structural performance.

[0042] One end of the support column 5 extends into the clearance notch 7 to prevent the support column 5 from interfering with the panel 2 when it rotates.

[0043] A button 10 is movably mounted on panel 2. The button 10 has an actuating post 11 that abuts against the support rod 3. When the button 10 is pressed, the actuating post 11 acts on the support rod 3, causing the support rod 3 to rotate upwards. A door 13 is located on the front side of cavity 1. A door hook 14 is mounted on door 13, and a hook hole 15 is located on the front side of cavity 1. When door 13 is closed, the door hook 14 engages with the hook hole 15, locking door 13. When the support rod 3 rotates upwards, it touches the door hook 14, causing the door hook 14 to disengage. Hole 15 unlocks and opens the door 13. The above structure is existing technology and will not be described in detail here. To open the microwave oven door 13, simply press button 10 on panel 2. The support rod 3 is installed on the positioning support hole 4 inside panel 2. There is no detachment or breakage, which will greatly improve the service life of the whole machine. At the same time, it ensures that the door 13 can move along the designed trajectory during the opening process without shaking, jamming or deviation, making the door opening operation smooth and reliable.

[0044] A sliding buckle 16 is provided around the button 10, and a mounting frame 17 is provided on the panel 2. A buckle 18 is provided around the mounting frame 17, and the sliding buckle 16 is slidably fastened to the buckle 18, thereby allowing the button 10 to be slidably mounted on the mounting frame 17. A guide hole 19 is provided on the mounting frame 17, and the actuating post 11 is movably disposed on the guide hole 19.

[0045] An elastic element 12 is provided between the button 10 and the mounting frame 17. The elastic element 12 is a spring. When the button 10 is released, the button 10 is reset under the elastic force of the elastic element 12, and then the support rod 3 rotates downward and resets under the action of gravity.

[0046] The strut 3 includes a rod body 20 and a connecting end 21. The support column 5 is set on the rod body 20. The action column 11 abuts against the rod body 20. When the button 10 is pressed, it acts on the rod 20 through the action column 11. When the strut 3 rotates upward, the connecting end 21 touches the door hook 14 so that the door hook 14 disengages from the hook hole 15.

[0047] The clearance notch 7 is used to avoid interference between the connecting end 21 of the support rod 3 and the panel 2 when the support rod 3 rotates. This ensures that the support rod 3 is in normal working condition without interference, and there will be no shaking, jamming or deviation. It increases strength and makes the door opening smooth, reducing problems such as door opening failure caused by the breakage of the positioning support hole 4. It also reasonably transmits the door opening force, avoiding damage to the button 10, switch and other components due to excessive or uneven door opening, and extending the overall life of the microwave oven.

[0048] A control box 22 is provided on one side of the cavity 1, and a panel 2 is provided on the front side of the control box 22.
