[0002] A steam generator is a mechanical device that heats water and consumes fuel and other energy sources to generate steam, and is usually divided into electric steam, gas, fuel, biomass steam generators, etc.

[0003] At present, electric steamers (or electric steamers, electric ovens) on the market generally heat the water in the water outlet tank through a heating tube to form steam, and output the steam for cooking. The temperature of the steam output by this method is generally not high and cannot meet the cooking needs of high-temperature steam. Content of the Utility Model

[0004] In order to overcome the existing technical defects, the purpose of the utility model is to provide a high-temperature steam generator to solve the above technical problems.

[0006] According to one aspect of the utility model, a high-temperature steam generator is designed, including: a liquid storage body, a heat conductor, a first heating tube, a second heating tube, and a steam tube. The liquid storage body is provided with a liquid injection port for communicating its internal liquid storage cavity with the outside. The heat conductor is arranged on the top of the liquid storage body. The first heating tube is connected to the lower end of the liquid storage body. The second heating tube and the steam tube are wrapped by the heat conductor. The heat conductor is used to transfer the heat energy generated by the second heating tube to the steam tube. The air inlet end of the steam tube extends to the upper part of the liquid storage cavity, and the air outlet end extends to the outside of the heat conductor.

[0007] Adopting the above technical solution, when the steam generator is in use, water can be injected into the liquid storage cavity through the liquid injection port. The liquid storage body is heated by the first heating tube, and then the water in the liquid storage cavity can be heated to form steam and enter the steam tube from the air inlet end. The heat conductor can be heated by the second heating tube, and the heat conductor transfers the heat energy to the steam tube, so as to heat the steam in the steam tube to form high-temperature steam and output it from the air outlet end, realizing the function of outputting high-temperature steam and meeting the cooking needs of high-temperature steam. The method of wrapping the second heating tube and the steam tube with the heat conductor can increase the heat transfer efficiency and improve the heat energy utilization efficiency. The steam generator has a simple structure, a smaller volume, is easier to install, has a lower cost, and has a good use effect.

[0008] In order to better solve the above technical defects, the utility model also has a better technical solution:

[0009] In some embodiments, the steam outlet is detachably connected with a steam nozzle. The steam nozzle is connected in a detachable manner, which facilitates its disassembly for cleaning or replacement, and solves the technical problem that the existing steam nozzle cannot be disassembled for cleaning and replacement.

[0010] In some embodiments, the second heating tube and the steam pipe are respectively in a spiral shape, and the second heating tube is arranged below the steam pipe. The steam pipe is arranged in a spiral shape to increase its length, thereby increasing the travel of the steam in the steam pipe, increasing the heating time of the steam, and further increasing the temperature of the output steam; the second heating tube is arranged below the steam pipe, which is beneficial to the transfer of heat energy to the liquid storage cavity and can heat the steam in the liquid storage cavity.

[0011] In some embodiments, a liquid discharge port is arranged at the bottom of the liquid storage body.

[0012] In some embodiments, the steam nozzle is threadedly connected to the steam outlet.

[0013] In some embodiments, a first pipe joint is connected at the position of the liquid injection port.

[0014] In some embodiments, a second pipe joint is connected at the position of the liquid discharge port.

[0015] In some embodiments, the liquid storage body includes a basin body and a cover body arranged on the top of the basin body. A heat conducting plate is connected to the bottom of the basin body, and the first heating tube is connected to the bottom of the heat conducting plate. BRIEF DESCRIPTION OF THE DRAWINGS
