Description

Technical Field

[0001] This utility model relates to the field of household kitchenware technology, specifically to an adjustable angle lighting device inside a microwave oven. Background Technology

[0002] The invention of the microwave oven has greatly improved people's life efficiency. It has revolutionized cooking methods, made it easy to operate, lowered the cooking threshold, and made it easy for kitchen novices to master. At the same time, it has promoted the booming development of the frozen food and ready-to-eat food industries, changed the public's dietary structure, and provided a convenient solution for heating food in offices, dormitories and other places, improving the kitchen environment. In addition, it is also widely used in public places such as hospitals and restaurants for heating food.

[0003] According to Chinese Patent No. CN212777502U, a lighting device and a microwave oven are disclosed. The microwave oven includes a cavity and an air hood. The cavity includes a connected top plate and a side plate. The air hood is disposed on the upper part of the side plate. The lighting device includes a lighting device installed on the upper surface of the top plate and / or the air hood. This utility model can make full use of the internal space of the microwave oven, reduce the damage of microwaves to the lighting device, and improve the stability of equipment operation.

[0004] However, the above technical features have the following shortcomings: The device achieves stable assembly of the lighting device in the cavity through a combination of plug-in and rigid connection. However, this fixing method limits the installation angle of the lighting device. During use, it cannot be adjusted according to the size of the food or the cooking scene, making it difficult to adapt to diverse cooking observation needs. In addition, the device forms a semi-enclosed structure through an air cover to guide hot air to the air inlet and prevent hot air from entering the electrical component installation area and preventing the lighting device from direct contact with heat energy. However, as the cavity heats up as a whole during the heating process, the lamp body is still directly exposed to the high temperature environment of the cavity. This cannot completely prevent the heat energy from damaging the lighting device, affecting the service life and working stability of the lighting device.

[0005] Therefore, an adjustable-angle lighting device for microwave ovens is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the limitations of the installation angle of the lighting device in existing microwave oven lighting devices, which makes it impossible to adjust according to the size of the food or the cooking scenario during use, and the fact that the semi-enclosed structure formed by the air cover cannot completely avoid the heat loss to the lighting device, thus affecting the service life and working stability of the lighting device.

[0007] The technical solution adopted to solve the above technical problems is: An adjustable-angle lighting device for a microwave oven includes an oven cavity and a sealed door hinged to the outer wall of the oven cavity. A front side plate is fixedly connected to the outer wall at the opening of the oven cavity. Lights are provided on both sides of the oven cavity. One end of each light is connected to a drive device that moves it. A side light box is fixedly connected to the outer wall on one side of the oven cavity. One of the drive devices and the light are both located inside the side light box. A light-transmitting plate is fixedly connected to the inner side wall of the oven cavity.

[0008] Preferably, the driving device includes limiting plates fixedly connected to both sides of the furnace cavity, with lead screws rotatably connected to the inner walls of both limiting plates, one end of each lead screw penetrating one side of the limiting plate and fixedly connected to a motor, brackets fixedly connected to the outer walls of the two motors, and the outer walls of the two brackets fixedly connected to the outer walls of the corresponding limiting plates.

[0009] Preferably, the outer walls of both lead screws are threaded with sliders, both sides of both limiting plates are provided with sliding grooves, the outer walls of both sliders are slidably connected to the sliding grooves provided on the corresponding limiting plates, and the two lights are respectively fixedly installed on the outer walls of one of the corresponding sliders.

[0014] This is a preferred technical solution of the present invention.

[0015] The beneficial effects of this utility model are as follows: This invention illuminates the oven cavity by using multiple lamps and tubes installed on the outer wall of the cavity. The lamps are moved and adjusted by a drive device connected to two lamps, avoiding the inability to adjust the light source according to various cooking scenarios and methods due to plug-in or rigid connections.

[0023] Example 1 exist Figures 1-5 In this invention, a technical solution is provided: an adjustable angle lighting device for a microwave oven, comprising an oven cavity 4 and a sealed door 2 hinged to the outer wall of the oven cavity 4. A front side plate 1 is fixedly connected to the outer wall at the opening of the oven cavity 4. Light lamps 20 are provided on both sides of the oven cavity 4. One end of each light lamp 20 is connected to a driving device that drives it to move. A side light box 11 is fixedly connected to the outer wall on one side of the oven cavity 4. One of the driving devices and the light lamps 20 are both located inside the side light box 11. A light-transmitting plate 22 is fixedly connected to the inner side wall of the oven cavity 4 corresponding to the position of the light lamp 20.

[0024] In one aspect of this embodiment, the driving device includes limiting plates 15 fixedly connected to both sides of the furnace cavity 4. The limiting plates 15 serve as the basic carrier of the driving device. The inner sidewalls of the two limiting plates 15 are rotatably connected to lead screws 16. One end of each lead screw 16 passes through one side of the limiting plate 15 and is fixedly connected to a motor 19. The motor 19 drives the lead screw 16 to rotate, providing a power source for the movement of the lamp 20. The outer sidewalls of the two motors 19 are fixedly connected to brackets 18. The outer sidewalls of the two brackets 18 are fixedly connected to the outer sidewalls of the corresponding limiting plates 15. The motors 19 are fixed to the outer sidewalls of the limiting plates 15 through the brackets 18, forming a closed-loop fixing structure to ensure stable assembly of the driving components.

[0025] In one aspect of this embodiment, the outer walls of the two lead screws 16 are threadedly connected to sliders 17, and the two limiting plates 15 are provided with sliding grooves on both sides. The outer walls of the two sliders 17 are slidably connected to the sliding grooves provided on the corresponding limiting plates 15. The sliders 17 are engaged with the lead screws 16 by threads, and their outer walls are embedded in the sliding grooves of the limiting plates 15 to form a sliding fit. The two lights 20 are respectively fixedly installed on the outer walls of the corresponding sliders 17.

[0026] In one aspect of this embodiment, a magnetron 7 is fixedly connected to the outer wall of the side light box 11, and a filter tube 8 is fixedly connected to the output end of the magnetron 7. The outer wall of one side of the filter tube 8 is fixedly connected to the outer wall of the side light box 11, and the outer wall of the other side of the filter tube 8 is fixedly connected to the outer wall of the top of the furnace cavity 4. The microwaves generated by the magnetron 7 are directionally transmitted into the furnace cavity 4 through the filter tube 8 to reduce microwave leakage. A stirring fan 9 is fixedly connected to the inner wall of the filter tube 8. The stirring fan 9 can disturb the microwaves in the filter tube 8, making the microwaves transmitted into the furnace cavity more evenly distributed and improving the heating effect.

[0027] In one aspect of this embodiment, light boxes 10 are provided on both the upper and lower sides of the furnace cavity 4. One side of each light box 10 is fixedly connected to the outer wall of the furnace cavity 4. A lamp tube 14 is fixedly connected to the inner wall of each light box 10. The lamp tubes 14 arranged symmetrically on the upper and lower sides and the side lights 20 form a multi-angle lighting system, reducing the lighting dead angles in the furnace cavity and improving the clarity of food observation.

[0028] In one aspect of this embodiment, an electric heating tube 13 is provided on the rear side of the oven cavity 4. A relay 12 is fixedly connected to the input end of the electric heating tube 13. The relay 12 can precisely control the on / off state and power of the electric heating tube 13 to achieve precise adjustment of the heating temperature. A back side plate 6 is fixedly connected to the outer side wall of the relay 12. The back side plate 6 and the front side plate 1 are jointly fixedly connected to a side plate 3. The back side plate 6 and the front side plate 1 are connected through the side plate 3 to form the overall frame structure of the microwave oven.

[0029] In one aspect of this embodiment, a cooling fan 21 is fixedly connected to the inner wall of the back panel 6. The cooling fan 21 exhausts the heat generated by the furnace cavity 4 and electrical components during operation, preventing the components from aging at high temperatures. A control panel 5 is fixedly connected to the outer wall of the front panel 1. The control panel 5 integrates all function control buttons for user convenience.

[0030] The working principle of this utility model is as follows: When the device is started, the control panel 5 issues a command to activate the lighting system. The lamps 20 on both sides of the oven cavity 4 are adjusted by the drive device: the motor 19 drives the lead screw 16 to rotate, so that the threaded slider 17 slides along the groove of the limiting plate 15, thereby changing the position of the lamps 20. Together with the lamp tubes 14 in the upper and lower light boxes 10 of the oven cavity, multi-angle three-dimensional lighting is formed. The light enters the oven cavity through the light-transmitting plate 22 to ensure that the user can clearly observe the state of the food. During the heating process, the microwaves generated by the magnetron 7 are transmitted into the oven cavity through the filter tube 8. The built-in stirring fan 9 disturbs the microwave flow, making the energy distribution more uniform. At the same time, the relay 12 controls the heating element 13 to start, which helps to increase the oven cavity temperature and meet different cooking needs. During operation, the cooling fan 21 on the back panel 6 works continuously to dissipate the heat generated by the furnace cavity and electrical components, ensuring that components such as the magnetron and motor operate at a suitable temperature.
