Description

Technical Field

[0001] This utility model relates to the field of cooking equipment technology, specifically a universal vehicle-mounted cooking steamer suitable for high plains areas. Background Technology

[0002] In high-altitude regions, traditional cooking equipment faces numerous challenges due to its unique geographical environment and climate. High altitude reduces atmospheric pressure, lowering the boiling point of water. Ordinary steamers struggle to generate sufficiently high-temperature steam to cook food, affecting its cooking effect and quality. Furthermore, the complex field environment in high-altitude plains places high demands on the stability and energy efficiency of cooking equipment. Most traditional steamers are designed for plains areas and cannot meet the needs of mobile kitchens in high-altitude regions. For example, common electric steamers often malfunction due to a lack of stable power supply in the field, while some gas-fired steamers suffer from incomplete combustion and low thermal efficiency at high altitudes. Therefore, there is an urgent need for a universal mobile kitchen steamer suitable for high-altitude plains areas. Summary of the Invention

[0003] The purpose of this invention is to provide a universal vehicle-mounted cooking steamer suitable for high plains areas.

[0004] This utility model is achieved using the following technical solution:

[0005] A universal vehicle-mounted cooking steamer suitable for high plains areas includes a steam generator, a fuel heater, and a steaming chamber. The steam generator includes a shell and a water supply pipeline. The shell has a water inlet, and a spirally arranged heat exchange tube is installed in the lower part of the shell. The bottom end of the heat exchange tube is connected to one end of the water supply pipeline through the water inlet, and the top end of the heat exchange tube is used to discharge steam. The heat exchange tube also has a water separation inlet. A steam-water separator is installed in the upper part of the shell. The steam-water separator has a mixed gas inlet, a separated steam outlet, and a separated liquid outlet. The mixed gas inlet of the steam-water separator... The outlet is connected to the top end of the heat exchange tube, and the outlet of the separated liquid of the steam-water separator is connected to the inlet of the separated water of the heat exchange tube; the fuel oil heater is used to provide heat to the steam generator. The fuel oil heater includes a heating chamber, which is equipped with a fuel injector, an ignition needle, an electric damper, and a fuel supply line. The electric damper is used to atomize the fuel sprayed from the fuel injector. The heating chamber is equipped with a fuel inlet, and one end of the fuel supply line is connected to the fuel injector through the fuel inlet; the steam chamber is equipped with a steam inlet, a steam outlet, and a drain line. The steam inlet of the steam chamber is connected to the separated steam outlet of the steam-water separator.

[0006] Principle Explanation: During use, the other end of the water supply line is connected to the vehicle's water tank, and the other end of the fuel supply line is connected to the vehicle's fuel tank. The fuel heater atomizes the fuel sprayed from the fuel injector through an electric damper. The electric damper can adjust the fan speed according to different altitudes to control the degree of fuel atomization. Then, the fuel is ignited by the ignition needle to fully and stably burn the fuel, improving thermal efficiency. The fuel heater then transfers the generated heat to the heat exchange tube through heat conduction, causing the water in the heat exchange tube to quickly vaporize into steam. After the steam passes through the steam-water separator, pure and dry gas is separated from the steam. The gas enters the steam chamber through the steam inlet on the steam chamber to steam heat the food, ensuring that the food is cooked.

[0007] Furthermore, the inner wall of the heat exchange tube is also provided with fins to increase the inner surface area of ​​the heat exchange tube and improve its heat exchange efficiency. In addition, this structure does not require additional installation space while ensuring heat exchange efficiency, making it suitable for the compact space requirements of vehicles.

[0008] Furthermore, the electric damper includes a turntable driven by a fan, with multiple blades distributed circumferentially on the turntable. The electric damper has a specific and standardized structure, is simple to implement, and has significant effects.

[0009] Furthermore, the fuel supply line is equipped with a fuel filter and a fuel pump to ensure a clean and stable fuel supply and improve combustion efficiency.

[0010] Furthermore, the steaming chamber is equipped with multiple layers of racks for placing steaming trays, which allows for easy adjustment of the placement height and the number of steaming trays according to the steaming requirements of different foods.

[0011] Furthermore, the inner liner of the steam chamber is made of stainless steel, with a smooth surface that is easy to clean.

[0012] Furthermore, the space between the inner liner of the steam chamber and the outer shell of the steam chamber is filled with heat insulation material to reduce heat loss and improve energy efficiency.

[0013] Furthermore, the steam-water separation device is a baffle-type steam-water separation device. Through multiple baffles, the steam changes its flow direction multiple times. Due to its greater inertia, the water droplets will collide with the obstacles, gather into large water droplets, and fall down. The gas can easily change its direction and bypass the obstacles, thereby separating the water droplets in the steam and quickly producing pure, dry gas. This structure is simple and easy to implement.

[0014] Furthermore, the steamer has a rectangular structure and the outer shell is made of stainless steel, which ensures the structural strength of the steamer and allows it to adapt to harsh outdoor environments.

[0015] Furthermore, the steam oven includes a shell, and the steam chamber, steam generator, and combustion heater are all arranged inside the shell.

[0016] The beneficial effects of this utility model are as follows: 1) Adaptability to high-altitude plains environment: Through the specially designed steam generator and fuel heater, it can work normally in the low-pressure environment of high-altitude plains, generating steam with sufficient temperature and pressure to ensure that food can be steamed thoroughly, solving the problem that traditional steamers cannot work effectively in high-altitude areas; 2) High efficiency and energy saving: The optimized combustion design of the fuel heater and the good heat insulation performance of the steaming chamber improve energy utilization efficiency and reduce fuel consumption; 3) The steamer structure is suitable for placement in the kitchen vehicle compartment, and can move flexibly with the field operation team, providing timely and reliable cooking support for field workers in high-altitude plains areas.
