Description

Technical Field

[0001] This utility model relates to the field of catering equipment technology, and in particular to a three-wheeled mobile food cart. Background Technology

[0002] Mobile food trucks have become a popular catering business model due to their high flexibility and relatively low investment. However, most existing mobile food trucks are converted from trucks or trailers, which suffer from problems such as excessive height, inconvenient loading and unloading, low internal space utilization, difficult maintenance, and insufficient customized design for specific dishes (such as steak). Tricycles, with their low chassis and narrow bodies, can maneuver flexibly through narrow streets and alleys, becoming an important vehicle for street food and community services. However, existing vehicles converted from tricycles to mobile food trucks have the following problems: 1. Low-chassis vehicles are prone to tipping over due to a higher center of gravity, limiting vertical space utilization and leading to a cramped layout of functional areas, small single-person operating space, low space utilization, and operator fatigue from prolonged bending; 2. Core kitchen equipment is difficult to fix in narrow spaces, and auxiliary components such as water tanks and gas cylinders are often externally mounted on the vehicle body, resulting in poor functional adaptability and the risk of collisions and leaks; 3. Water tanks and equipment are mostly fixed installations, making cleaning and maintenance extremely inconvenient; 4. The lack of targeted lighting and smoke extraction designs affects operational efficiency and safety. Utility Model Content

Furthermore, the movable design of the wastewater and clean water tanks facilitates cleaning and maintenance. The LCD advertising screen provides advertising, while the LED linear wall washer lights and lighting strips offer illumination, further enhancing the truck's ease of use and overall practicality.

[0013] 2. Because the support frame further refines the space division through the first support plate, second support plate, third support plate, horizontal plate, and upper and lower partitions, it clearly defines the specific locations of the gas cylinder compartment, the tray storage drawer, the washing pool compartment, the sewage tank compartment, and the clean water tank compartment. Each functional area is equipped with a corresponding compartment door or drawer, so all components are stored neatly and are easy to access, avoiding interference between different functional components, and further improving the efficiency of interior space management and the safety of use of the dining car.

[0014] 3. Because the upper plate of the clean water tank is equipped with a water intake port and a cleaning port with a cover, and the cover is fixed by a locking seat and a locking buckle, and the side plate is equipped with a water inlet and a water level gauge, it is convenient to inject clean water and monitor the water level in real time. At the same time, the design of the cleaning port facilitates cleaning of the inside of the water tank, and the locking structure ensures that the cover is fixed reliably, which improves the convenience and sealing of the clean water tank.

[0015] 4. Because the wastewater tank has a wastewater inlet and a lockable cleaning port on the upper panel, and the side panels are equipped with an overflow prevention pipe and a drain pipe, and the clean water tank is connected to the faucet via a water pump, and the drain outlet of the washing pool is connected to the wastewater tank inlet, a closed-loop management of clean water supply and wastewater collection can be achieved. The overflow prevention pipe prevents wastewater from overflowing, and the lock secures the cleaning port, improving the safety and convenience of using the wastewater tank and ensuring the hygiene of the dining car.

[0016] 5. Because the range hood adopts a downdraft design, a flue pipe is installed inside the gas tank compartment, and the two ends of the flue pipe are connected to the exhaust port of the range hood and the exhaust outlet of the first side panel of the compartment, respectively. Therefore, cooking fumes can be quickly discharged from the compartment through a dedicated pipe, avoiding the accumulation of fumes inside, which pollutes the environment and affects operation, thus improving the air quality and user comfort inside the food cart.

[0017] 6. Since the outer surfaces of all compartment doors and drawers, such as the gas cylinder compartment door and the cleaning pool compartment door, are equipped with embedded handles, the handles do not protrude from the surface, avoiding bumps and interference. At the same time, it is convenient for operators to quickly open and close the compartment doors and drawers, further improving the ease of use and the overall aesthetics of the structure.

[0018] 7. Since the LCD advertising screen is hinged to the upper crossbeam and the upper flip plate, and the lower crossbeam is welded with hooks, and the upper flip plate has corresponding hanging rods on the inside, the advertising screen can be flipped and fixed to the hanging rods by the hooks when the upper flip plate is open, so as to realize the advertising display function. When closed, it can be stored inside the upper flip plate without occupying extra space, thus improving the flexibility of the advertising screen and the space utilization rate.

[0019] 8. Since the first and second plate storage drawers are equipped with separate racks for bowls and plates, bowls and plates of different sizes can be classified and stored separately to avoid damage caused by stacking and collision. At the same time, it is convenient to quickly retrieve them, improving the neatness of tableware storage and the ease of use. Attached Figure Description
