Description

Technical Field

[0001] This invention relates to the field of kitchen carts, and in particular to an emergency kitchen cart. Background Technology

[0002] Mobile kitchens are specialized vehicles used by the Chinese military to provide food support in field conditions. They provide food support during exercises, disaster relief, and field training. Existing mobile kitchens typically have kitchen equipment such as steamers inside the vehicle. In the field, cooks use the vehicle as their kitchen to prepare meals. While this on-the-spot meal preparation results in relatively fresh food, it is inefficient, taking a considerable amount of time to complete. Furthermore, due to the large number of personnel, a single mobile kitchen can only prepare a limited amount of food, thus requiring multiple mobile kitchens to meet the needs of a large number of personnel. To improve meal efficiency, fast food can be used instead of on-the-spot prepared meals. Before eating, the fast food only needs to be heated in a steamer, significantly saving meal time. Currently, some kitchen vehicles are equipped with steamers. However, these steamers have a small capacity and can only heat a small amount of food, which cannot meet the catering needs of personnel. If a large-capacity steamer is used, the loading and unloading of food that needs to be heated will consume a lot of manpower, resulting in low work efficiency. Furthermore, if manual loading and unloading is used, it is difficult to ensure the cleanliness of the steamer, affecting the hygiene and safety of the food. In addition, when using a large-capacity steamer to heat food, the steam demand is very high, and a large amount of water is required, resulting in high water consumption. This makes it difficult to use in water-scarce environments in the field. Moreover, if the steam emission is large, it is easy to expose the location, which is not conducive to the concealment of military operations. Summary of the Invention

[0003] The purpose of this invention is to address the issues described in the background art regarding the limited food preparation capacity of existing kitchen carts, where a single cart can only meet the needs of a small number of people and has low food preparation efficiency. While existing steamers cannot meet the needs of a large number of people when used to heat food, large-capacity steamers present problems such as difficulties in food loading and unloading, hygiene and safety, high water consumption, large steam output, and easy exposure of the location. Therefore, this invention provides an emergency kitchen cart.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an emergency kitchen vehicle, comprising a vehicle body, a generator set, a kitchen cargo box, an electrical box, and an electrical control box. The electrical box is electrically connected to the generator set, and the electrical control box is electrically connected to the electrical box. The generator set and the kitchen cargo box are fixedly mounted on the vehicle body. The kitchen cargo box includes an outer casing and a steamer. The steamer is located inside the outer casing. An outer casing door is provided on the rear, left, or right side of the outer casing. A steamer door is provided on one side of the steamer, located on the side corresponding to the outer casing door. An upper door switch drive mechanism and a lifting drive mechanism are provided on the outer casing to drive the outer casing door to open and close. The upper door switch drive mechanism can drive the outer casing door to rotate to a vertical or horizontal state to close or open the outer casing. An automatic loading and unloading mechanism is provided on the inner side of the outer casing door. When the outer casing door is in a horizontal state and located... When the steamer door is open, the automatic loading and unloading mechanism can drive the material on the outer door into the steamer or drive the material at the steamer door to be discharged onto the outer door. The outer casing is equipped with a water storage tank, a heating water tank, a water pump, and an electrical control box. The outlet of the water storage tank is connected to the inlet of the heating water tank through a water pipe and a water pump. The heating water tank can heat the water to generate steam. The generated steam enters the steamer from the bottom or side of the steamer. A steam outlet is provided on the top or upper side wall of the steamer. The steam outlet is connected to the water storage tank through a steam pipe. The steam outlet of the water storage tank is connected to the air blower through a pipe. The air blower is equipped with an exhaust port. The electrical control box is connected to the heating water tank, the upper door switch drive mechanism, the lifting drive mechanism, and the automatic loading and unloading mechanism via signals. The electrical box is connected to the heating water tank, the upper door switch drive mechanism, the lifting drive mechanism, and the automatic loading and unloading mechanism via electrical connections.

[0005] As a further improvement to the above solution, the outer casing door includes an upper door and a lower door. The upper door is movably connected to the outer casing, and the outer casing is equipped with an upper door opening and closing drive mechanism. This mechanism drives the automatic opening and closing of the upper door. The lower door is connected to the outer casing via a lifting guide sliding assembly, which is equipped with a lower door flipping drive device. This device drives the lower door to flip. This configuration, separating the outer casing door into an upper and lower door, reduces the driving force required for the lifting mechanism during the lifting process, thus reducing energy consumption.

[0006] As a further improvement to the above solution, there are two sets of lifting guide sliding components for the lower door. The two sets of lower door lifting guide sliding components are respectively set on the left and right sides of the lower door. Each set of lower door lifting guide sliding components includes a vertical guide tube and a sliding seat. The sliding seat includes a sliding arm and an outer side plate. The sliding arm is inserted into the vertical guide tube. Guide rollers are provided on both sides of the sliding arm. The guide rollers slide in cooperation with the inner wall of the vertical guide tube. The lower end of the sliding arm is provided with a connecting part extending towards the lower door. The left and right sides of the lower door are movably connected to the connecting parts on the corresponding sides of the sliding arm. A groove is provided on the side wall of the vertical guide tube opposite to the lower door. The width of the groove is adapted to the width of the sliding arm. The sliding arm extends through the groove to the outside of the vertical guide tube. The outer end of the sliding arm is fixedly connected to the outer side plate. The lower door flipping drive device is a lower door drive cylinder. There are two sets of lower door drive cylinders. One end of the lower door drive cylinder is movably connected to the lower door. The other end of the lower door drive cylinder is movably connected to the corresponding side outer side plate. With this design, the sliding seat can extend and retract within the guide tube during the lifting and lowering of the lower door. Furthermore, the rolling of the rollers reduces friction with the guide tube, making the lifting and lowering of the sliding seat more sensitive.

[0007] As a further improvement to the above solution, the lifting drive mechanism includes a hydraulic cylinder, a movable pulley, a left upper guide wheel, a left lower guide wheel, a left traction belt, a right upper guide wheel, a right lower guide wheel, and a right traction belt. The hydraulic cylinder is horizontally positioned at the lower edge of the outer casing door. The movable pulley is positioned to the left of the hydraulic cylinder, and the push rod of the hydraulic cylinder is fixedly connected to the movable pulley. The left lower guide wheel is positioned to the left of the movable pulley, the left upper guide wheel is positioned above the left lower guide wheel, the right lower guide wheel is positioned to the right of the hydraulic cylinder, and the right upper guide wheel is positioned above the right lower guide wheel. One end of the left traction belt is fixedly connected to the sliding arm of the left lifting guide sliding assembly, and the other end of the left traction belt passes sequentially through the left upper guide wheel, the left lower guide wheel, the right lower guide wheel, and the movable pulley, with its end fixed to the lower side of the hydraulic cylinder. One end of the right traction belt is fixedly connected to the sliding arm of the right lifting guide sliding assembly, and the other end of the right traction belt passes sequentially through the right upper guide wheel, the right lower guide wheel, and the movable pulley, with its end fixed to the upper side of the hydraulic cylinder. This design uses a single hydraulic cylinder to simultaneously drive the left and right traction belts via a movable pulley, thereby synchronously raising and lowering the left and right sides of the lower door. This keeps the moving platform horizontal. Compared to existing technologies that use two vertically positioned hydraulic cylinders to control the door's raising and lowering separately, this design is simpler, eliminating one hydraulic cylinder and correspondingly reducing half of the hydraulic piping connected to it. This significantly simplifies the hydraulic system's structure. Furthermore, the hydraulic cylinder's horizontal placement at the lower edge of the outer box door facilitates connection to the hydraulic piping, further simplifying the piping structure. Because of the movable pulley, the hydraulic cylinder's stroke is reduced to half the lower door's raising and lowering height, resulting in a smaller footprint. This design also significantly reduces the volume occupied by the lifting drive mechanism on both sides of the outer box door, making the overall structure of the outer box more compact.

[0008] As a further improvement to the above solution, the outer casing is equipped with an upper limit switch, a middle limit switch, and a lower limit switch. The upper limit switch is located in the middle of the outer casing, the middle limit switch is located at the same height as the bottom of the steamer, and the lower limit switch is located below the middle limit switch and near the bottom of the outer casing. All three switches are located next to the sliding seat. This configuration allows for control of the lower door's lifting height. When the upper door of the outer casing is opened, the lower door first rises to the position of the upper limit switch, then flips from a vertical to a horizontal position, and then descends to the position of the lower limit switch. Food and racks to be heated can then be loaded onto the lower door. After loading, the lower door stops rising when it reaches the middle limit switch. This position coincides with the height of the plate chain drive mechanism on the steamer, allowing the automatic loading and unloading mechanism and the plate chain drive mechanism to transport the food and racks to be heated into the steamer.

[0009] As a further improvement to the above solution, the upper door switch drive mechanism includes an upper door drive rod and a limit switch. One end of the upper door drive rod is movably connected to the outer casing, and the push rod of the upper door drive rod is movably connected to the upper door via a connecting rod. The limit switch is located at the top of the outer casing. When the upper door is fully opened, the limit switch is triggered, controlling the upper door drive rod to stop the opening action. By setting the upper door motion sensor and the limit switch, the opening action of the upper door can be automatically controlled.

[0010] As a further improvement to the above solution, the automatic loading and unloading mechanism includes a slide rail, a drive cylinder, and a moving platform. The slide rail is fixed to the inner side of the lower door, and when the lower door is in a horizontal state, the slide rail is oriented towards the steamer. Multiple sliders are provided at the bottom of the moving platform, slidingly mounted on the slide rail, which vertically limits the sliders. Several rollers are also provided at the bottom of the moving platform, positioned on both sides and contacting the inner surface of the lower door. One end of the drive cylinder is movably connected to the inner side of the lower door, and the other end is movably connected to the moving platform. Multiple sets of rollers are distributed on the moving platform, their orientation perpendicular to the slide rail. A sprocket is provided at the end of each roller. A drive motor is provided on the moving platform, with a drive sprocket at its output end. The drive sprocket drives each roller to rotate synchronously via a chain, thereby achieving material loading and unloading. With this setup, when food is fed into the steamer, the moving platform rises to the same height as the chain drive mechanism. The drive cylinder then pushes the moving platform towards the steamer, moving it next to the chain drive mechanism. The rotation of the rollers on the moving platform moves the food and rack onto the chain drive mechanism, which then feeds the food and rack into the steamer. When food is removed from the steamer, the moving platform rises to the same height as the chain drive mechanism. The drive cylinder then moves the moving platform next to the chain drive mechanism, which in turn moves the food and rack towards the moving platform. Once the food and rack are on the moving platform, the drive cylinder retracts, and the rollers rotate, moving the food and rack to the center of the moving platform. After the lower door completes its descent, the heated food and rack can be removed from the moving platform.

[0011] As a further improvement to the above solution, the moving platform is equipped with a cargo detection switch, a front limit switch, a rear limit switch, and a shelf limit switch. The cargo detection switch is located in the middle of the moving platform, and the shelf limit switch is located on the front side of the moving platform. The shelf limit switch can contact the trigger block on the shelf. The front limit switch and the rear limit switch are both located on the lower door. The front limit switch is located at a position corresponding to the middle of the moving platform, and the rear limit switch is located at a position corresponding to the rear side of the moving platform. A trigger block is located at the rear end of the moving platform, and the position of the trigger block corresponds to the position of the rear limit switch and the front limit switch. When food and the rack are loaded onto the moving platform, a cargo detection switch is triggered, allowing subsequent operations such as lifting or feeding the food and rack into the steamer. The front limit switch restricts the extension position of the drive cylinder, the rear limit switch restricts its retraction position, and the rack limit switch triggers the chain drive mechanism. When food and the rack are fed from the moving platform into the steamer, the trigger block on the rack moves to the rack limit switch position, triggering the rack limit switch and initiating the chain drive. When heated food is output from the steamer, the food and rack move onto the moving platform via the chain drive. Under the action of the rollers, the trigger block on the rack moves to the rack limit switch position, triggering the rack limit switch and stopping the chain drive.

[0012] As a further improvement to the above solution, the steamer is equipped with a plate chain drive mechanism, a plate chain motor is located outside the steamer, and a drive shaft is located on the wall of the steamer. The plate chain motor drives the plate chain drive mechanism through the drive shaft. Air holes are distributed on the drive plate of the plate chain drive mechanism. A front-end sensor, a rear-end sensor, and a cargo sensor are installed inside the steamer. The front-end sensor and the rear-end sensor are respectively located inside the steamer near the steamer door, and the cargo sensor is located on the inner side wall of the steamer. All the front-end sensor, the rear-end sensor, and the cargo sensor are waterproof and high-temperature resistant sensors.

[0013] As a further improvement to the above solution, the steamer is equipped with a steamer door drive rod, a first limit switch, and a second limit switch. The steamer door drive rod is located on the side wall of the steamer and on both sides of the steamer door. One end of the steamer door drive rod is movably connected to the side wall of the steamer, and the other end of the steamer door drive rod is movably connected to the steamer door. The first limit switch is located at the top of the steamer. When the steamer door is fully opened, the first limit switch is triggered, controlling the steamer door drive rod to stop the opening action. The second limit switch is located on the side wall of the steamer. When the steamer door is fully closed, the second limit switch is triggered, controlling the steamer door drive rod to stop the closing action.

[0014] This invention has the following positive effects: 1) The emergency kitchen cart of this invention can automatically load and unload heated food, avoiding manual handling, saving labor, and improving the efficiency of food loading and unloading. Furthermore, automatic loading and unloading ensures the cleanliness and hygiene of the steamer interior, guaranteeing food safety; 2) The emergency kitchen cart of this invention can heat a large amount of food at once. When fully loaded, it can meet the dietary needs of one to two thousand people, greatly improving food preparation efficiency and thus significantly reducing the number of kitchen carts required; 3) The steamer of this emergency kitchen cart has a wide range of uses, capable of heating and steaming various foods, such as rice, vegetables, meat, fast food, corn, etc. Any food that can be steamed can be processed. Using the steamer of this invention for heating can greatly expand its application range; 4) The emergency cooking vehicle of this invention can generate a large amount of steam by heating the water tank, ensuring sufficient steam when heating food. The steam outlet and steam pipe enter the water storage tank, where the steam is cooled and liquefied, and then recycled and stored in the water tank, reducing water consumption. A small amount of unliquefied water vapor enters the air box and is further liquefied under the cooling effect of the air box. The air box has multiple ventilation holes, and the cold air from the outside can lower the internal temperature of the air box when passing through the ventilation holes, further accelerating the liquefaction of water vapor. With this setting, it can avoid the waste of water caused by the large discharge of water vapor, and also avoid the exposure of the location due to the large discharge of water vapor.

Detailed Implementation

[0031] The technical solution of the present invention will be clearly and completely described below through embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1-15 As shown, the emergency kitchen vehicle of the present invention includes a vehicle body 1, a generator set 2, a kitchen cargo box 3, an electrical box 8, and an electrical control box 7. The generator set 2 and the kitchen cargo box 3 are fixedly mounted on the vehicle body 1.

[0033] like Figures 1-3 The vehicle body 1 shown can be a truck or a transport vehicle used in existing kitchen trucks.

[0034] Generator set 2 can be a diesel generator set or a solar power generation device. Generator set 2 is used to provide power to the cooking container.

[0035] Electrical box 8 is electrically connected to generator set 2. Electrical control box 7, heating water tank 5, upper door switch drive mechanism 3111, lifting drive mechanism 3123, and automatic loading / unloading mechanism 3124 are all electrically connected to electrical box 8. Electrical control box 7 is also signal-connected to heating water tank 7, upper door switch drive mechanism 3111, lifting drive mechanism 3123, and automatic loading / unloading mechanism 3124. Depending on the specific design of upper door switch drive mechanism 3111, lifting drive mechanism 3123, automatic loading / unloading mechanism 3124, and electrical control box 7, there can be various implementation schemes for electrical control box 7. For example, the electrical control box includes a hydraulic controller and an electric controller. The hydraulic controller controls the movement of each hydraulic cylinder through hydraulic pipelines and hydraulic valves, realizing the opening and closing of the steamer, the opening and closing of the upper and lower doors of the outer casing, as well as the movement of the moving platform on the lower door. The electric controller can control the movement of various electric components to achieve corresponding automatic actions, such as the extension and retraction of the electric telescopic rod, the start and stop of the chain motor, and the rotation of the rollers on the moving platform.

[0036] The cooking container 3 includes an outer casing 31 and a steamer 32. The outer casing 31 can be rectangular. Typically, the door of the outer casing 31 is located on the rear side, and the corresponding steamer door 321 is also located on the rear side. Of course, depending on the actual design requirements, the door can also be located on the side wall of the outer casing 31, and the steamer door 321 is correspondingly located on the side. The following describes an embodiment of the invention with the door located on the rear side of the outer casing as an example. The structural principle of the scheme with the door located on the side is basically the same as that of the scheme with the door located at the rear.

[0037] like Figure 3As shown, the steamer 32 is housed inside the outer casing 31. Depending on the dimensions of the outer casing 31 and the steamer 32, several sets of steamers can be arranged side-by-side inside the outer casing 31. For example, in the embodiment shown in the attached figure, two sets of steamers are provided inside the outer casing. Each set of steamers can have its own steamer door, allowing for independent control of opening and closing; alternatively, the steamer doors of the two sets of steamers can be connected as a single unit.

[0038] like Figure 2 As shown, the door of the outer casing 31 can be divided into an upper door 311 and a lower door 312. This arrangement can reduce the weight of the lifting door, save energy, and reduce the space occupied.

[0039] like Figure 3 and 4 As shown, the upper door 311 of the outer casing 31 is movably connected to the outer casing 31, and the outer casing 31 is provided with an upper door switch drive mechanism 3111. The upper door is automatically opened and closed by the upper door switch drive mechanism 3111. The upper door switch drive mechanism 3111 can be a hydraulic cylinder or an electric telescopic rod, etc. One end is movably connected to the outer casing, and the other end is directly movably connected to the upper door, or it is connected to the upper door through a connecting rod. For example, for a hydraulic cylinder, the cylinder sleeve can be connected to the outer casing and the push rod can be connected to the upper door, or the cylinder sleeve can be connected to the upper door and the push rod can be connected to the upper door. The upper door switch drive mechanism also includes a limit switch, which is set on the top of the outer casing. When the upper door is fully opened, the limit switch is triggered, controlling the upper door drive rod to stop the door opening action.

[0040] like Figure 7-8As shown, the lower door 312 of the outer casing 31 is connected to the outer casing 31 via a lifting guide sliding assembly 3121. There are two sets of the lifting guide sliding assembly 3121, with each set positioned on the left and right sides of the lower door 312. Each set includes a vertical guide tube 31211 and a sliding seat. The sliding seat includes a sliding arm 31212 and an outer side plate 31213. The sliding arm 31212 is inserted into the vertical guide tube 31211. Guide rollers 31214 are provided on both sides of the sliding arm 31212, and these rollers slide against the inner wall of the vertical guide tube 31211. The lower end of the sliding arm 31212 has a connecting portion 31215 extending towards the lower door 312. The left and right sides of the lower door 312... The sliding arms 31212 on each side are movably connected to the connecting parts 31214 on the corresponding sides. A slot 31216 is provided on the wall surface of the vertical guide tube 31211 opposite to the lower door 312. The width of the slot 31216 is adapted to the width of the sliding arm 31212. The sliding arm 31212 extends through the slot 31216 to the outside of the vertical guide tube 31211, and the outer end of the sliding arm 31212 is fixedly connected to the outer side plate 31213. The lower door flipping drive device 3122 is a lower door drive cylinder. There are two sets of lower door drive cylinders. One end of the lower door drive cylinder is movably connected to the lower door 312, and the other end is movably connected to the corresponding side outer side plate 31213. Its connection principle is similar to that of the upper door opening and closing drive mechanism. For example, if a hydraulic cylinder is used for the lower door flipping drive device, the cylinder sleeve can be connected to the lower door, and the push rod can be connected to the sliding seat; alternatively, the cylinder sleeve can be connected to the sliding seat, and the push rod can be connected to the lower door.

[0041] like Figure 7-10As shown, a lifting drive mechanism 3123 is also provided on the outer casing 31. The lifting drive mechanism 3123 includes a hydraulic cylinder 31231, a movable pulley 31232, a left upper guide wheel 31234, a left lower guide wheel 31235, a left traction belt 31236, a right upper guide wheel 31237, a right lower guide wheel 32133, and a right traction belt 31238. The movable pulley 31232 is located to the left of the hydraulic cylinder 31231, and the push rod of the hydraulic cylinder 31231 is fixedly connected to the movable pulley 31232. The left lower guide wheel 32135 is located to the left of the movable pulley 31232. The left upper guide wheel 31234 is located above the left lower guide wheel 31235. The right lower guide wheel 31233 is located to the right of the hydraulic cylinder 31231. On one side, the upper guide wheel 31237 on the right is positioned above the lower guide wheel 31233 on the right. One end of the left traction belt 31236 is fixedly connected to the sliding arm 31212 of the left lifting guide sliding assembly. The other end of the left traction belt 31236 passes sequentially through the upper guide wheel 31234 on the left, the lower guide wheel 31235 on the left, the lower guide wheel 31233 on the right, and the movable pulley 31232, with its end fixed to the lower side of the hydraulic cylinder 31231. One end of the right traction belt 31238 is fixedly connected to the sliding arm 31212 of the right lifting guide sliding assembly. The other end of the right traction belt 31238 passes sequentially through the upper guide wheel 31237 on the right, the lower guide wheel 31233 on the right, and the movable pulley 31232, with its end fixed to the upper side of the hydraulic cylinder 31231. By setting a movable pulley 31232, the lifting height of the lower door can reach twice the extension distance of the hydraulic cylinder 31231, ensuring that the lifting height of the lower door meets the requirements. The aforementioned left and right traction belts pass through the movable pulley and the lower right guide wheel from different directions. Therefore, to reduce friction on the movable pulley surface and the lower right guide wheel, the movable pulley and the lower right guide wheel can include two coaxially arranged rollers. These two rollers are independent of each other and can rotate freely relative to the pivot. The left and right traction belts pass over different rollers. This arrangement reduces the frictional resistance of the lifting drive mechanism, decreases frictional wear on parts, and improves energy efficiency.

[0042] This solution is only one implementation shown in the attached figure. In the design, the same technical effect can be achieved by changing the installation direction of the chain of the lifting drive mechanism according to the above design principle.

[0043] like Figure 4As shown, the outer casing 31 is equipped with an upper limit switch 313, a middle limit switch 314, and a lower limit switch 315. The upper limit switch 313 is located in the middle of the outer casing 31, the middle limit switch 314 is located at the same height as the bottom of the steam oven 32, and the lower limit switch 315 is located below the middle limit switch 314 and near the bottom of the outer casing 31. The upper limit switch 313, middle limit switch 314, and lower limit switch 314 are all located next to the sliding seat. The upper limit switch 313 is used to raise the lower door 312 to the position of the upper limit switch 313 before the lower door 312 can be rotated by the lower door flipping drive device 3122 to rotate the lower door 312 to a horizontal state and open the lower door 312. The middle limit switch 314 is used to stop the lower door 312 from rising to the position of the middle limit switch 314 when heated food is loaded into or removed from the steamer 32. The automatic loading and unloading mechanism 3124 on the lower door 312 then delivers the food loaded on the lower door 312 into the steamer 32 or moves the food in the steamer 32 from the steamer 32 onto the lower door 312. The lower limit switch 315 is used to control the lowest descent position of the lower door 312. When the lower door 312 moves to the lower limit switch 315, heated food is loaded onto or removed from the lower door 312.

[0044] like Figure 10-12As shown, an automatic loading and unloading mechanism 3124 is provided on the lower door 312. The automatic loading and unloading mechanism 3124 includes a slide rail 31241, a drive cylinder 31242, and a moving platform 31243. The slide rail 31241 is fixed on the inner side of the lower door 312, and when the lower door 312 is in a horizontal state, the slide rail 31241 is oriented towards the steamer 32. Multiple sliders are provided at the bottom of the moving platform 31243. The sliders are slidably mounted on the slide rail 31241, and the slide rail 31241 can limit the sliders vertically. Several rollers 31244 are provided at the bottom of the moving platform 31243. The rollers 31244 are arranged on both sides of the moving platform 31243. On the side, roller 31244 contacts the inner surface of lower door 312. One end of drive cylinder 31242 is movably connected to the inner surface of lower door 312, and the other end of drive cylinder 31242 is movably connected to moving platform 31243. Multiple sets of rollers 31245 are distributed on moving platform 31243. The setting direction of rollers 31245 is perpendicular to the setting direction of slide rail 31241. A sprocket is provided at the end of each roller 31245. A drive motor 31246 is provided on moving platform 31243. The output end of drive motor 31246 is provided with drive sprocket. Drive sprocket drives each roller 31245 to rotate synchronously through chain to realize the loading and unloading of materials. The slide rail 31241 not only allows the moving platform 31243 to move linearly along its direction, but also, when a shelf is mounted on the moving platform 31243 and the shelf moves forward, causing the center of gravity of the moving platform to shift forward, the slide rail 31241 can vertically limit the slider at the bottom of the moving platform 31243, preventing the front end of the moving platform 31243 from tilting or even tipping over. In the design, two pairs of slide rails 31241 can be designed, with at least two sliders corresponding to each slide rail 31241 to enhance the vertical limiting effect on the moving platform. The cross-sectional shape of the slide rail can be set to be wider at the top and narrower at the bottom, for example, a trapezoidal or approximately "Ω" shaped cross-section. The slide grooves are located on the lower part of both sides of the slide rail.

[0045] like Figure 10-12As shown, the aforementioned moving platform 31243 is equipped with a cargo detection switch 31248, a front limit switch 31249, a rear limit switch 31240, and a shelf limit switch 31247. The cargo detection switch 31248 is located in the middle of the moving platform 31243, and the shelf limit switch 31247 is located on the front side of the moving platform 31243. The shelf limit switch 31247 can contact the trigger block on the shelf. The front limit switch 31249 and the rear limit switch 31240 are both located on the lower door 312. The front limit switch 31249 is located at a position corresponding to the middle of the moving platform 31243, and the rear limit switch 31240 is located at a position corresponding to the rear side of the moving platform 31243. A trigger block is located at the rear end of the moving platform 31243, and the position of the trigger block corresponds to the position of the rear limit switch 31240 and the front limit switch 31249.

[0046] When two sets of steamers 32 are installed inside the outer casing 31, two sets of automatic loading and unloading mechanisms 3124 are installed on the lower door to simultaneously load food that needs to be heated into the two steamers, or to simultaneously output heated food from the two steamers, thereby further improving the efficiency of loading and unloading food.

[0047] like Figure 13 As shown, the steam oven 32 is equipped with a steam oven door drive rod 3211, a first limit switch 3212, and a second limit switch 3213. The steam oven door drive rod 3211 is located on the side wall of the steam oven 32 and on both sides of the steam oven door 321. One end of the steam oven door drive rod 3211 is movably connected to the side wall of the steam oven 32, and the other end of the steam oven door drive rod 3211 is movably connected to the steam oven door 321. The first limit switch 3212 is located on the top of the steam oven 32. When the steam oven door 321 is fully open, the first limit switch 3212 is triggered, controlling the steam oven door drive rod 3211 to stop the opening action. The second limit switch 3213 is located on the side wall of the steam oven 32. When the steam oven door 321 is fully closed, the second limit switch 3213 is triggered, controlling the steam oven door drive rod 3211 to stop the closing action.

[0048] like Figure 14-15As shown, a plate chain transmission mechanism 322 is provided inside the steamer 32, and a plate chain motor 3221 is provided outside the steamer 32. A transmission shaft 3222 is provided on the wall of the steamer. The plate chain motor 3221 drives the plate chain transmission mechanism through the transmission shaft 3222. The plate chain transmission mechanism includes a chain and a transmission plate 3223, which is fixedly connected to the chain. Air holes 3224 are distributed on the transmission plate 3223 of the plate chain transmission mechanism. A front-end sensor 323, a rear-end sensor 324, and a cargo sensor 325 are provided inside the steamer 32. The front-end sensor 323 and the rear-end sensor 324 are respectively located inside the steamer 32 near the steamer door. The cargo sensor 325 is located on the inner side wall of the steamer. All the front-end sensor 323, the rear-end sensor 324, and the cargo sensor 325 are waterproof and high-temperature resistant sensors. When food to be heated is fed into the steamer 32, after the first rack is loaded into the steamer, the chain moves towards the interior of the steamer. When the trigger block on the rack triggers the cargo sensor 325, the chain drive mechanism stops moving. Then the second rack is loaded, and similarly, when the trigger block on the second rack triggers the cargo sensor 325, the chain drive mechanism stops moving. This continues until the last rack is loaded into the steamer. At this point, the trigger block fixed on the chain, corresponding to the front sensor 323, rotates to the position of the front sensor 323, triggering the front sensor 323 to send a signal indicating that the steamer 32 is now full of racks containing food to be heated. When the food is heated and output from the steamer 32 to the moving platform, the chain drive mechanism stops moving when the rack is output to the rack limit switch 31247 on the moving platform. This continues until the last rack is output from the steamer 32. At this point, the trigger block fixed on the chain and corresponding to the rear sensor 324 moves to the position of the rear sensor 324, triggering the rear sensor 324 to send a signal indicating that all racks in the steamer have been output.

[0049] like Figure 5 and 6 As shown, the outer casing 31 is equipped with a water storage tank 4, a heating water tank 5, a water pump 6, and an electrical control box 7. The outlet of the water storage tank 4 is connected to the inlet of the heating water tank 5 via a water pipe and the water pump 6. The heating water tank 5 heats the water to generate steam. The generated steam enters the steam oven 32 through the air hole 3224 on the transmission plate 3223 at the bottom of the steam oven 32. A steam outlet is provided on the top or upper side wall of the steam oven 32. The steam outlet is connected to the water storage tank 4 via a steam pipe. The steam outlet of the water storage tank 4 is connected to the air box 9 via a pipe. The air box 9 is equipped with an exhaust port. The electrical control box 7 is electrically connected to the heating water tank 5. Multiple sets of heating water tanks 5 can be designed as needed, and multiple sets of heating water tanks are evenly distributed at a certain interval at the bottom of the steam oven 32. Multiple sets of electrical control boxes 7 can also be designed, and the electrical control box 7 is electrically connected to the heating water tanks 5.

[0050] like Figure 6 As shown, to facilitate the monitoring of water levels in the water storage tank 4 and the heating water tank 5, water level sensors 41 are installed in both tanks. When the water level in the heating water tank 5 is low, water is pumped from the water storage tank 4 to the heating water tank 5 by a water pump 6. To facilitate water replacement in both the water storage tank 4 and the heating water tank 5, drain pipes 42 are installed on both tanks.

[0051] When the emergency kitchen vehicle of the present invention is in use, the upper door of the outer body is flipped from a vertical state to an inclined state or a horizontal state by the control box to open the upper door. Then the lower door is opened. Specifically, the lifting drive mechanism drives the lower door to rise to the position of the upper limit switch, and then the lower door flips to the rear of the vehicle body and opens by the lower door flipping drive device. The lower door rotates to a horizontal state, and then the lifting drive mechanism drives the lower door to fall to the position of the lower limit switch. The steamer door drive lever is controlled by the electrical control box to open the steamer. Then, a forklift loads the food to be heated from the loading rack onto the moving platform on the lower door. The lower door is then raised by the electrical control box until it reaches the middle limit switch position. At this point, the moving platform is directly opposite the steamer. The drive cylinder of the automatic loading and unloading mechanism pushes the moving platform towards the steamer. When the trigger block on the moving platform reaches the front limit switch position, the drive cylinder stops extending. The motor of the automatic loading and unloading mechanism drives the roller to rotate, which in turn pushes the loading rack into the steamer. When the trigger block on the loading rack reaches the loading rack limit switch on the moving platform, the plate chain motor inside the steamer starts, activating the plate chain transmission mechanism. The plate chain motor drives the drive shaft to rotate, which in turn drives the chain drive, moving the transmission plate and thus the loading platform. The rack carries the food to be heated into the steamer. When the trigger block on the rack moves to the position of the cargo sensor inside the steamer, the chain drive mechanism stops, and the drive cylinder of the automatic loading and unloading mechanism on the lower door retracts, moving the moving platform away from the steamer. When it returns to the initial position, the trigger block on the moving platform triggers the rear limit switch, the drive cylinder stops retracting, and then the lifting drive mechanism moves the lower door down to the position of the lower limit switch. The above process is repeated to continue automatically loading the food to be heated into the steamer until the steamer is full. At this point, the trigger block on the chain drive mechanism moves to the position corresponding to the front sensor inside the steamer, triggering the front sensor to indicate that the steamer is full of food to be heated. Then the steamer door is closed, and the steamer is started via the electrical control box to begin steaming the food. When steaming food, water from the storage tank is first pumped into the heating tank by a water pump. The heating device in the heating tank starts heating and generates steam. The steam is transported to the bottom air inlet of the steamer through the steam pipe. The steam enters the steamer and heats the food. The steam that rises to the top of the steamer enters the steam pipe through the steam outlet and then enters the storage tank. In the storage tank, the steam is cooled into a liquid state. The unliquefied steam is transported from the steam outlet of the storage tank to the blower through the steam pipe. In the air duct of the blower, the steam is further liquefied, and the remaining small amount of steam is discharged from the exhaust port at the top of the blower.Once the food in the steamer is cooked, the steamer stops heating via the electrical control box. The control box also opens the steamer door and raises the rear door. Then, the drive cylinder of the automatic loading and unloading mechanism extends, moving the moving platform on the rear door to the side of the chain conveyor inside the steamer. The chain conveyor then moves the carrying rack towards the moving platform. When the trigger block on the carrying rack moves to the position corresponding to the carrying rack limit switch, it triggers the limit switch, stopping the chain conveyor. The rollers on the moving platform start rotating under the drive of the motor, moving the carrying rack to the center of the moving platform. Then, the drive cylinder of the automatic loading and unloading mechanism retracts, moving the moving platform away from the steamer. The moving platform then descends to the position of the lower limit switch, allowing a forklift to transport the cooked food to the dining area. This process is repeated until the last carrying rack is removed from the steamer. At this point, the trigger block on the chain conveyor moves to the position of the rear limit switch, triggering the rear limit switch and sending a signal indicating that all the food in the steamer has been removed.
