Description

Technical Field

[0001] This utility model belongs to the field of mobile catering vehicle technology, specifically relating to a multi-functional mobile catering vehicle. Background Technology

[0002] Mobile catering carts are highly portable and flexible, widely used on trains, high-speed trains, and bullet trains. They provide passengers with the convenient service of purchasing food and drinks while seated, eliminating the need to go to the dining car and saving time and effort. After the food is prepared in the kitchen, it is placed on the mobile catering cart. To maintain the food's temperature for a longer period, the cart is usually equipped with a warming compartment to minimize heat loss. When a passenger needs food, the compartment door is opened to retrieve it for sale. However, with a large quantity of food typically stored in a single warming compartment, the frequent retrieval of food while the cart is in motion causes the compartment door to open repeatedly. This results in repeated heat loss, leading to insufficient temperature for subsequent meals and negatively impacting the passenger experience. Utility Model Content

[0003] This utility model provides a mobile catering multi-functional vehicle, which has the feature of reducing heat release inside the catering vehicle.

[0004] This utility model provides the following technical solution: It includes a mobile catering cart and a set of wheels. Two insulated silos are fixedly connected to the inner wall of the mobile catering cart. Several support plates are rotatably connected to the inner walls of each of the two insulated silos. These support plates are evenly distributed vertically within their respective insulated silos. Several space partitions are fixedly connected to the top of each support plate. These space partitions are rotatably connected to the inner walls of their respective insulated silos. Several cabinet doors are installed on both sides of each of the two insulated silos. These cabinet doors control the sealing and opening of the space between the two support plates. Side clearance openings are provided on both sides of the mobile catering cart to allow space for the cabinet doors.

[0005] The mobile catering vehicle is equipped with several material trays on both sides, and the material trays are fixedly connected between the two insulated silos. The material trays are evenly distributed vertically.

[0006] Each of the two insulated silos is provided with an inner support cylinder. Several bearing plates and space partition plates are fixedly connected to the side wall of the corresponding inner support cylinder. The inner support cylinder drives the corresponding bearing plates and space partition plates to rotate synchronously. Heaters are installed on the inner walls of the two inner support cylinders to heat the fluid medium on the inner walls of the inner support cylinders.

[0007] Both the insulated silo and the space partition plate have internal hollow grooves, and each of the internal hollow grooves is filled with heat insulation cotton.

[0008] Each of the two inner support cylinders is fixedly connected to a connecting rod at its top end. Both connecting rods pass through the top of the mobile catering cart. A rotating handle is fixedly connected to the top end of each connecting rod, and the rotating handle is rotatably connected to the top of the mobile catering cart.

[0009] The beneficial effects of this utility model are: by controlling the rotation of the support plate, each individual storage space can be rotated sequentially to the position corresponding to the cabinet door, and the food inside the individual storage space can be taken out, while the other individual storage spaces remain sealed. This allows the individual storage space where the food has been taken out to exchange with the outside air, while the individual storage space where the food has not been taken out remains sealed and insulated, reducing heat loss and helping to ensure that unsold food maintains a good temperature, thus improving the eating experience for passengers who purchase food later.

[0016] Please see Figures 1-4The present invention provides the following technical solution: including a mobile catering cart 1 and a set of wheels 11, two insulated silos 2 are fixedly connected to the inner wall of the mobile catering cart 1, and several bearing plates 21 are rotatably connected to the inner wall of each of the two insulated silos 2. The several bearing plates 21 are evenly distributed vertically in the corresponding insulated silos 2, and several space partition plates 211 are fixedly connected to the top of each of the several bearing plates 21. The space partition plates 211 are rotatably connected to the inner wall of the corresponding insulated silos 2. Several cabinet doors 22 are installed on both sides of the two insulated silos 2. The cabinet doors 22 control the sealing and opening of the space between the two bearing plates 21. Side clearance openings 12 are opened on both sides of the mobile catering cart 1 to allow space for the cabinet doors 22.

[0017] In this implementation plan: the mobile catering cart 1 moves via wheels 11. Two side openings 12 expose the interior of the mobile catering cart 1, facilitating observation and use of the internal components by staff. The mobile catering cart 1 supports all components of the device. Both the front and rear ends of the mobile catering cart 1 are rounded, reducing the risk of collisions during movement and facilitating operation. Two insulated silos 2 are symmetrically distributed. A support plate 21 supports several corresponding space partitions 211. These space partitions 211 equally divide the space formed by the insulated silos 2 and the support plate 21, creating several individual storage spaces. These individual storage spaces are not interconnected to prevent temperature exchange and improve temperature control stability within each individual storage space. Qualitatively, the support plate 21 carries the food, and the cabinet door 22 allows the internal space of the insulated silo 2 to be connected with the external space. By opening the cabinet door 22, the support plate 21 is controlled to rotate, and the support plate 21 drives the space partition plate 211 and the food to rotate synchronously. When the individual storage space between the two space partition plates 211 is aligned with the cabinet door 22, the individual storage space is opened, and the food inside the individual storage space can be taken out, while the other individual storage spaces remain sealed. This allows the individual storage space where the food has been taken out to exchange with the outside air, while the individual storage space where the food has not been taken out remains sealed and insulated, reducing heat loss and helping to ensure that unsold food maintains a good temperature, thus improving the eating experience for passengers who purchase food later.

[0018] The mobile catering cart 1 has several material trays 13 on both sides, which are fixedly connected between two insulated silos 2. The material trays 13 are evenly distributed vertically. The two insulated silos 2 are fixed and do not move or rotate, so that the insulated silos 2 can stably support the material trays 13. The material trays 13 between the two insulated silos 2 can carry goods that do not need to be insulated, and the goods in the material trays 13 are not obstructed by other components, making it easy for passengers to observe and select, and improving the space utilization of the catering cart.

[0019] Both insulated silos 2 are equipped with inner support cylinders 23. Several bearing plates 21 and space partition plates 211 are fixedly connected to the corresponding side walls of the inner support cylinders 23. The inner support cylinders 23 drive the corresponding bearing plates 21 and space partition plates 211 to rotate synchronously. Heaters 231 are installed on the inner walls of both inner support cylinders 23, which heat the fluid medium inside the inner walls of the inner support cylinders 23. The inner support cylinders 23 are located at the center of the insulated silos 2 and the bearing plates 21. The inner support cylinders 23, together with the space partition plates 211, achieve spatial division and sealing. The inner support cylinders 23 support the bearing plates 21 and the corresponding space partition plates 211. The space partition 211 provides support and rotation drive. By controlling the rotation of the inner support cylinder 23, the inner support cylinder 23 drives the bearing plate 21 to rotate. The bearing plate 21 drives the space partition 211 and the food to rotate synchronously, so that each individual storage space can rotate to the cabinet door 22 for retrieval. It is simple and practical. The inner support cylinder 23 has a hollow cavity structure and stores the circulating medium inside. The heater 231 heats the medium, so that the inner support cylinder 23 can release the heating temperature to the internal space of the insulated silo 2, and heat the food that has not been sold for a long time without the need to heat the food separately after it is taken out.

[0020] Both the insulated silo 2 and the space partition plate 211 have internal hollow grooves 24, and several internal hollow grooves 24 are filled with heat insulation cotton 25. The insulated silo 2 and the space partition plate 211 form a heat insulation barrier through the corresponding internal hollow grooves 24, which prevents heat from being lost through conduction, convection and radiation. The heat insulation cotton 25 can further reduce heat loss and improve the heat preservation effect of the equipment on the food.

[0021] Two connecting rods 3 are fixedly connected to the top of each of the two inner support cylinders 23. Both connecting rods 3 pass through the top of the mobile catering cart 1. A rotating handle 31 is fixedly connected to the top of the connecting rod 3. The rotating handle 31 is rotatably connected to the top of the mobile catering cart 1. The inner support cylinder 23 supports the corresponding connecting rod 3, and the connecting rod 3 supports the corresponding rotating handle 31. The inner support cylinder 23 extends out of the mobile catering cart 1. The staff can drive the rotating handle 31 to rotate from the outside, so that the rotating handle 31 can drive the connecting rod 3 to rotate. The connecting rod 3 drives the inner support cylinder 23 to rotate. The inner support cylinder 23 drives several bearing plates 21 and space partition plates 211 to rotate, so that each individual storage space can be rotated to the cabinet door 22 position in sequence for retrieval.

[0022] The working principle and usage process of this utility model are as follows: When the catering cart is in use, the crew pushes the equipment forward. The front and rear ends of the mobile catering cart 1 are both arc-shaped, which reduces the risk of collision during movement and facilitates operation. When a passenger needs food during the journey, the crew opens the cabinet door 22, opening the corresponding individual storage space. Food can then be taken out and sold. Food in the individual storage space can be retrieved, while the other individual storage spaces remain sealed. This allows the space where food has been retrieved to exchange air with the outside air, while the space where food remains unretrieved... The individual storage spaces are always sealed and insulated, reducing heat loss and ensuring that unsold meals remain at a good temperature, thus improving the dining experience for subsequent passengers. When retrieving meals, the rotating handle 31 is controlled to rotate, which in turn drives the connecting rod 3 to rotate, which in turn drives the inner support cylinder 23 to rotate. The inner support cylinder 23 then drives several bearing plates 21, space partition plates 211, and the meals to rotate, allowing the next individual storage space to rotate to the position corresponding to the cabinet door 22. This allows each individual storage space to be rotated sequentially to the cabinet door 22 for retrieval, making it simple and practical.
