[0033] The vehicle-mounted solid-state microwave oven comprises an outer box 1, an inner box 2 and a bearing seat 3. The bearing seat 3 can be embedded in the vehicle body, the inner box 2 is fixed in the outer box 1, the outer box 1 is placed on the bearing seat 3, and the outer box 1 and the bearing seat 3 are detachably connected. The inner box 2 and the outer box 1 form a heat dissipation chamber 101 and a heat source chamber 102 which are interconnected. The heat source chamber 102 is provided with a magnetron, a waveguide, a fan and other devices. The microwave generated by the magnetron enters the inner box 2 through the waveguide to heat the food; the output end of the fan can be provided with a guide tube, which can guide the wind to the heat dissipation chamber 101. The wind generated by the fan can enter the inner box 2, the heat dissipation chamber 101 and the heat source chamber 102, so as to dissipate the heat of the microwave oven as a whole. The heat dissipation chamber 101 is C-shaped, so as to cover the inner box 2, dissipate the heat of the inner box 2 as a whole, and greatly reduce the transfer of heat to the outer box 1. A heat dissipation component 4 is provided in the heat dissipation chamber 101, and the heat dissipation component 4 adjusts and disturbs the air passing through to reduce the temperature of the air section, thereby realizing cooling of the outer box 1 and the inner box 2. The bearing seat 3 includes a seat body 31 and a cooling component 32, the seat body 31 includes a receiving cavity 301, the cooling component 32 is placed in the receiving cavity 301, the bottom of the outer box 1 extends into the receiving cavity 301, the heat dissipation chamber 101 and the heat source chamber 102 are both connected to the receiving cavity 301, and the air can circulate between the heat dissipation chamber 101, the heat source chamber 102 and the receiving cavity 301, forming a complete air flow cycle, realizing the overall comprehensive cooling of the microwave oven.

[0034] The inner box 2 includes a top plate 21, a U-shaped frame 22, a serving tray 23 and a bottom assembly 24. The top plate 21 and the U-shaped frame 22 are connected to form a square frame structure, so that the heat dissipation chamber 101 and the heat source chamber 102 can be formed in cooperation with the outer box 1. The bottom assembly 24 is placed in the inner box 2 and on the bottom of the U-shaped frame 22. The bottom assembly 24 includes a positioning frame 241 and a placement plate 242. The placement plate 242 is embedded in the positioning frame 241, and a heat insulation chamber 201 is formed between the placement plate 242 and the U-shaped frame 22. A plurality of recessed grooves 202 are provided on the storage plate 242, and a positioning hole 203 is opened in the middle of the storage plate 242. The storage plate 23 is composed of a plate body 231 and a limiting protrusion 232. The limiting protrusion 232 is fixed to the bottom of the plate body 231. The limiting protrusion 232 can pass through the positioning hole 203 and extend into the insulation cavity 201. A positioning protrusion 233 that cooperates with the recessed groove 202 is provided on the outer wall of the plate body 231.

[0035] The U-shaped frame 22 not only supports the internal serving tray 23 and the bottom assembly 24, but also connects to the external heat dissipation chamber 101 and the heat source chamber 102 through the vent holes on the side walls to ensure air circulation. The design of the U-shaped frame 22 ensures that the heat energy inside the microwave oven is concentrated on the serving tray 23, thereby maximizing the heating efficiency.

[0036] The serving tray 23 is used to place the food to be heated. The serving tray 23 is designed with a recessed groove 202 and a limiting protrusion 232. The limiting protrusion 232 is located at the bottom of the tray body 231 and can pass through the positioning hole 203 to extend into the heat insulation cavity 201, ensuring that the serving tray 23 can be firmly fixed in the inner box 2 to prevent movement during the bumpy driving of the vehicle. The design of the serving tray 23 not only ensures the stability of the food container during the driving of the vehicle, but also ensures that the container is always located in the center area of ​​the microwave oven, ensuring the uniform radiation of microwaves, thereby improving the uniformity and efficiency of heating. The recessed groove 202 is located on the placement plate 242, and a positioning protrusion 233 is provided on the outer wall of the serving tray 23 to match it. The combination of the recessed groove 202 and the positioning protrusion 233 enables the serving tray 23 to be firmly stuck in the groove during the placement process to prevent sliding or tilting. This matching design not only improves the stability of the serving tray 23, but also ensures that the container will not be displaced during the heating process, thereby improving the consistency of heating.

[0037] The positioning frame 241 cooperates with the storage plate 242 to form a supporting function for the bottom structure. The design of the bottom assembly 24 makes the load-bearing and heat dissipation structure of the entire inner box 2 more stable, ensuring that the bottom structure can bear the pressure from the storage tray 23 during the operation of the device, and preventing the bottom components from being deformed due to uneven heating.

[0038] An insulating cavity 201 is formed between the storage plate 242 and the U-shaped frame 22. The design of the insulating cavity 201 can effectively reduce the conduction of heat to the bottom of the inner box 2 during heating, thereby preventing the device from overheating. The insulating cavity 201 further extends the service life of the microwave oven by isolating the direct conduction of the heat source, and improves the safety of the device during long-term use.

[0039] The serving tray 23 can be firmly fixed in the inner box 2 by means of the limiting protrusion 232, the recessed groove 202 and the positioning hole 203, so that it will not shake or shift even when the vehicle is bumpy, thus ensuring the stability of the food during the heating process and the uniformity of the heating. The vents on the U-shaped frame 22 are connected to the heat dissipation chamber 101 and the heat source chamber 102, ensuring that the air can flow through the heat dissipation chamber 101 and the heat source chamber 102 during the operation of the microwave oven, forming an effective heat dissipation circulation system to prevent the equipment from overheating. The recessed groove 202 of the serving tray 23 cooperates with the positioning protrusion 233 to further enhance the stability of the food container and reduce the collision problem inside the equipment during the driving of the vehicle. With this design, the food can always be in the best position for microwave heating, thus improving the heating efficiency and effect.

[0040] The heat dissipation assembly 4 includes a pressure difference component 41, a spoiler component 42 and a flow guide component 43. The pressure difference component 41 includes a plate body 411 and a plurality of air nozzles 412 embedded in the plate body 411. The plurality of air nozzles 412 are evenly arranged. The plate body 411 is fixed between the outer box 1 and the inner box 2 and sealed so that air can only pass through the air nozzles 412. The air nozzles 412 are composed of a conical tube and a round tube connected to each other. The larger side of the conical tube orifice faces the direction of air flow, and the orifice of the round tube is much smaller than the orifice of the conical tube. The air enters from the larger orifice of the conical tube and is discharged from the orifice of the round tube. The air flow rate through the air nozzle 412 increases. Under the action of the pressure difference, the temperature of the air blown out through the air nozzle 412 decreases. The spoiler member 42 includes a frame 421 and a spoiler plate 422 fixed on the frame 421. The spoiler plate 422 corresponds to the air nozzle 412 one by one. The spoiler plate 422 is bowl-shaped and the convex surface of the spoiler plate 422 faces the air outlet of the circular tube. The flow guide member 43 is composed of a plurality of groups of flow guides 431 and a flow equalizer 432. The plurality of groups of flow guides 431 are placed between the flow equalizer 432 and the spoiler member 42. The flow guide 431 includes two flow guides arranged in an interlaced manner, wherein one flow guide is fixed on the inner wall of the outer box 1 and the other flow guide is fixed on the outer wall of the inner box 2. The flow equalizer 432 is provided with a plurality of evenly arranged flow equalizer holes 401.

[0041] The air nozzle 412 is composed of a conical tube and a circular tube connected to each other, the opening of the conical tube is larger, and the opening of the circular tube is smaller. The air velocity of the air entering through the large diameter of the conical tube will increase when passing through the small diameter of the circular tube. This acceleration process utilizes the principle of air pressure difference to reduce the temperature of the air flow, thereby achieving preliminary cooling of the air. The air nozzles 412 of the pressure difference component 41 are evenly arranged to evenly distribute them throughout the heat dissipation chamber 101, ensuring that all parts of the device can effectively dissipate heat.

[0042] The spoiler component 42 includes a frame 421 and a plurality of spoilers 422, each spoiler 422 is bowl-shaped, and the convex surface faces the air outlet of the air nozzle 412. When the airflow ejected from the air nozzle 412 encounters the convex surface of the bowl-shaped spoiler 422, the airflow will be forced to change direction and generate disturbances, which can effectively disperse the airflow and prevent the airflow from directly impacting the inner wall of the device or local overheating. The disturbance of the airflow enables the cold air to cover every corner of the heat dissipation chamber 101 more evenly, thereby improving the heat dissipation efficiency. Through the disturbing effect of the spoiler 422, the airflow can form a more uniform temperature distribution in the device, avoid the formation of local hot spots, and improve the overall heat dissipation effect.

[0043] The staggered guide plate design can effectively guide the airflow through the heat dissipation chamber 101, ensuring that the air will not be blocked or trapped during the flow, thereby maximizing the coverage of the cold air. The staggered design of the guide plate helps the airflow flow in different directions, so that all areas of the heat dissipation chamber 101 can be cooled.

[0044] The flow equalizing holes 401 on the flow equalizing plate 432 can refine the airflow and evenly distribute it to different areas, avoiding the airflow being concentrated in a certain area, resulting in uneven heat dissipation. The function of the flow equalizing plate 432 is to disperse the airflow from a single strong cold point, so that the temperature of different parts inside the device is kept balanced, thereby improving the overall heat dissipation effect.

[0045] The combination of the pressure difference component 41, the spoiler component 42 and the guide component 43 forms a complete air circulation system. The airflow is accelerated to cool down by the pressure difference component 41, and after being dispersed by the spoiler component 42, it is guided by the guide component 43 to flow through the entire heat dissipation chamber 101, and finally forms an efficient circulation heat dissipation path. The whole process ensures that the cold air flows continuously in the heat dissipation chamber 101, so that the temperature inside the device continues to decrease. Through the mutual cooperation of the three, the airflow can flow evenly throughout the entire device to prevent the occurrence of local overheating. The disturbance effect of the spoiler component 42 and the guiding effect of the guide component 43 are combined to avoid the stagnation of the airflow or the temperature accumulation in the local area, and realize the uniform temperature distribution inside the device. The pressure difference acceleration, spoiler dispersion and guide uniformization of the heat dissipation component 4 jointly ensure that the inside of the device is always in an effective cooling state, avoiding the performance degradation or safety hazards caused by overheating when the microwave oven works for a long time.

[0046] The cooling assembly 32 includes a mounting member 321, a receiving box 322, a cooling pipe 323 and an isolation member 324. The mounting member 321 is detachably connected to the base 31. The receiving box 322 is fixed on the mounting member 321. The cooling pipe 323 is embedded in the receiving box 322. An elastic clamp 325 and a placement ring 326 are provided on the inner wall of the receiving chamber 301. The bottom of the outer box 1 is provided with a protrusion 11 that cooperates with the elastic clamp 325. The protrusion 11 is located on the bottom plate of the outer box 1. The mounting member 321 includes a mounting plate 321a and a plurality of groups of supporting members 321b. The mounting plate 321a is placed on the placement ring 326. The receiving box 322 is embedded on the mounting plate 321a. The plurality of groups of supporting members 321b are fixed on the mounting plate 321a and arranged around the receiving box 322. The supporting members 321b are each composed of at least two crossed arc plates, and the arc plates are used to support the outer box 1. The base 31 is provided with a sealing ring 329 that matches the outer box 1. The sealing ring is made of rubber, silicone and other materials. When the outer box 1 is installed on the base 31, the sealing ring 329 can be installed between the outer box 1 and the base 31 to seal the two, effectively preventing mosquitoes, mice and the like from entering. The sealing ring of the corresponding specifications can be selected according to the microwave ovens of different sizes.

[0047] The supporting seat 3 is embedded in the vehicle body, and can fix the microwave oven body (a combination of an outer box and an inner box). A fixing plate 33 can be provided on both sides of the supporting seat 3. When the microwave oven body is placed on the supporting seat 3, it is located between the two fixing plates 33. A threaded hole corresponding to the mounting hole is provided on the side wall of the outer box, and a fastener such as a screw can be passed through the fixing hole and threadedly connected with the threaded hole, thereby fixing the microwave oven body on the supporting seat 3. Similarly, in order to make the microwave oven body more stably fixed on the supporting seat 3, a gasket can be installed between the fixing plate 33 and the outer box 1 to ensure that the microwave oven body is not easily shaken by external force.

[0048] When the microwave oven body is installed on the supporting seat 3, the bottom of the outer box 1 extends into the accommodating cavity 301 of the supporting seat 3. At this time, there is a gap between the outer box and the supporting seat 3, and the heat generated by the microwave oven can be discharged from the gap between the two, ensuring that the two are not easily overheated; the sealing ring 329 can also be installed between the outer box 1 and the supporting seat 3 to perform surface sealing on the two, which can ensure that the heat generated by the microwave oven only circulates between the two, and the heat is not easily affected by the vehicle.

[0049] The mounting member 321 firmly mounts the components of the cooling assembly 32 on the bearing seat 3, and the detachable design facilitates the user to install, maintain and replace the equipment. The mounting member 321 makes the cooling assembly 32 and the structure of the whole machine more modular, which is convenient for later repair and maintenance.

[0050] The elastic card plate 325 cooperates with the raised portion 11 on the outer wall of the outer box 1 to firmly fix the outer box 1 in the accommodating chamber 301 and provide a stable support structure for the equipment. The elastic card plate 325 can collide with the raised portion 11 on the outer box 1 to ensure that the outer box 1 can be firmly fixed in the accommodating chamber 301 in a vehicle-mounted environment, and avoid the shaking or displacement of the outer box 1 when the vehicle is bumpy. Because the card plate is elastic, it can not only firmly fix the outer box 1, but also absorb part of the vibration during the driving of the vehicle, reduce the impact on the equipment, and extend the life of the equipment. The cross design of the arc plate provides multi-point support, ensuring that the outer box 1 is firmly fixed in the mounting member 321, preventing the equipment from shaking or tilting during driving, and improving the overall stability. The support member 321b disperses the weight of the outer box 1 through the arc plate, avoiding excessive force on a single point, effectively extending the service life of the equipment, and ensuring that the equipment remains stable under high load or long-term operation.

[0051] Since the mounting member 321, the housing box 322, the cooling tube 323 and the isolation member 324 are all modularly designed, the user can easily replace or maintain the components. The design also allows the type of cooling medium or the design of the cooling tube 323 to be adjusted according to actual needs, thereby enhancing the flexibility and adaptability of the device.

[0052] The side wall of the U-shaped frame 22 is provided with a first vent 103 connected to the heat dissipation chamber 101 and a second vent 104 connected to the heat source chamber 102. The air in the inner box 2 can enter the heat dissipation chamber 101 through the first vent 103, and the air in the heat source chamber 102 can enter the inner box 2 through the second vent 104. The bottom upper cover of the outer box 1 is provided with a third vent 105 connected to the heat dissipation chamber 101 and a fourth vent 106 connected to the heat source chamber 102. The outer box 1 includes an electric component chamber 107 connected to the heat source chamber 102. The electronic components are all placed in the electric component chamber 107. The heat generated by the electronic components will also be taken away by the cold air entering the heat source chamber 102, so as to achieve heat dissipation and cooling of the electronic components. The storage box 322 contains a cooling medium, which can be water, air, etc. A semiconductor refrigerator can be provided in the storage box 322 for cooling water or air. The cooling tube 323 is in the shape of a serpentine tube or a mosquito coil tube. A first receiving cover 327 is provided on one pipe mouth of the cooling tube 323. The first receiving cover 327 faces the heat dissipation chamber 101 and corresponds to the third air vent 105. A second receiving cover 328 is provided on the other pipe mouth of the cooling tube 323. The second receiving cover 328 faces the heat source chamber 102 and corresponds to the fourth air vent 106.

[0053] The isolation member 324 includes a T-shaped plate and a heat conductive sheet. The bottom end of the T-shaped plate extends into the containing box 322 and is fixedly connected to the containing box 322. The heat conductive sheet is made of heat conductive silicone. The T-shaped plate is made of copper, iron or other materials. The heat conductive sheet is fixed to the top of the T-shaped plate, and the heat conductive sheet is in contact with the bottom of the outer box 1.

[0054] The container 322 contains a cooling medium (such as water, air or cooling oil) and is in close contact with the cooling pipe 323. The cooling medium has a large heat capacity and can effectively absorb the heat in the air flowing through the cooling pipe 323 to cool the air in the cooling pipe 323.

[0055] The snake-shaped or mosquito-repellent-coil-shaped design of the cooling tube 323 greatly increases the contact area with the cooling medium and improves the efficiency of heat transfer. The design of the cooling tube 323 being connected to the heat dissipation chamber 101 and the heat source chamber 102 forms an internal airflow circulation system. The air flowing through the cooling tube 323 is heat-carried away by the cooling medium, and the cold air is discharged into the heat source chamber 102 and the heat dissipation chamber 101, thereby fully dissipating the heat of the microwave oven.

[0056] The T-shaped plate and the heat conducting sheet are both made of heat conducting materials, which can effectively conduct heat and isolate the heat source from the cooling system to prevent heat from spreading to other areas of the device. The design of the heat conducting sheet ensures that heat is quickly transferred to the cooling medium in the receiving box 322, reducing the retention of heat inside the device, thereby accelerating the cooling of the device.

[0057] The isolation component 324 not only helps to conduct heat effectively, but also isolates the heat source chamber 102 from the heat dissipation chamber 101 and the cooling component 32, so that the air flows in the direction of the heat source chamber 102 → the heat dissipation chamber 101 → the cooling pipe 323 → the heat source chamber 102, making the air flow in a circulation manner, thereby improving the heat dissipation efficiency of the overall system.

[0058] The cooling tube 323 is embedded in the container box 322 and is in close contact with the cooling medium, ensuring that the heat from the heat source chamber 102 can be quickly transferred to the cooling medium and dissipated. At the same time, the cooling tube 323 is connected with the heat dissipation chamber 101 and the heat source chamber 102 to form a closed air circulation system. The air is initially cooled through the heat dissipation component 4, and then continues to be cooled through the cooling tube 323. Finally, the cold air returns to the heat source chamber 102. Finally, the cold air can enter the heat dissipation chamber 101 to continue the heat dissipation cycle, and can enter the electrical component chamber 107 to cool the electronic components. The cooling medium in the container box 322 absorbs the heat in the cooling tube 323, and dissipates heat through natural cooling or semiconductor refrigerators to ensure that the heat exchange is not easy to affect the interior of the vehicle.

[0059] The isolation member 324 effectively isolates the heat source chamber 102 from the heat dissipation system through the heat conductive sheet and the T-shaped plate, preventing the heat from spreading to other parts of the device. At the same time, the heat conductive sheet can quickly transfer the heat to the cooling pipe 323, reducing the heat retention and accelerating the cooling efficiency of the device.

Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
