Description

Technical Field

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

[0003] Chinese patent CN219318401U discloses a high-temperature steam generator thermal insulation device and heating equipment. The high-temperature steam generator thermal insulation device includes: a first heating mechanism 1 and a second heating mechanism 2. The first heating mechanism 1 is used to heat the fluid once, and the fluid after the primary heating enters the second heating mechanism 2 for secondary heating to a higher temperature. The second heating mechanism 2 includes: a second heating body 201 and a first pipeline 202. The first pipeline 202 is wrapped around the second heating body 201, and the heat generated by the second heating body 201 heats the fluid in the first pipeline 202. The high-temperature steam generator of this structure has a split structure in which the first and second heating mechanisms are connected by pipelines. The overall structure is relatively complex and costly. In addition, the entire generator system occupies a large amount of product space, the heat utilization rate of steam transmitted through pipelines is low, and the split high-temperature evaporator causes loss of steam pressure.

[0007] By adopting the above technical solution, when the steam generator is used, water can be injected into the lower chamber through the liquid injection port, and the lower part of the shell can be heated by the first heating tube, and then the water in the lower chamber can be heated, so that the water forms steam and passes through the through hole on the partition into the upper chamber. The steam can be heated by the second heating tube to form high-temperature steam, and output from the steam outlet, realizing the function of outputting high-temperature steam and meeting the cooking needs of high-temperature steam.

The spiral disk shape of the second heating pipe can increase its contact surface with the steam, thereby improving the heating effect of the steam.

[0010] In some embodiments, the steam outlet is connected to a steam conduit, and a steam nozzle is detachably connected to the top of the steam conduit. The detachable connection between the steam nozzle and the steam conduit facilitates removal of the steam nozzle for cleaning or replacement, resolving the technical problem of existing steam nozzles being unable to be removed for cleaning or replacement.

[0011] In some embodiments, the steam nozzle is threadedly connected to the steam casing.

[0015] In some embodiments, a drain port is provided at the bottom of the shell, and a second pipe joint is connected to the drain port.

[0016] In some embodiments, the side and top surfaces of the housing are respectively provided with heat insulating layers, thereby achieving the effect of heat insulation. BRIEF DESCRIPTION OF THE DRAWINGS
