Steam generator with water scale removal function

Abstract

The invention discloses a steam generator with a water scale removal function. The steam generator with the water scale removal function comprises a body valve element. The body valve element is usedfor allowing a water source to be fed and heating a water body. A water inlet is formed in the bottom of the body valve element, and a steam outlet is formed in the top of the body valve element. Thebody valve element comprises an outer core and an inner core. The outer core is of a hollow structure, the inner core is arranged in the hollow structure of the outer core, and a cavity which allows the water to circulate is reserved between the outer core and the inner core. The heating operation is conducted by the body valve element, and therefore the water body which flows through the cavity can be heated to evaporate, and then the steam flows out of the steam outlet. An elastic coil is arranged in the cavity and arranged in the mode of encircling the outer wall of the inner core. In addition, the elastic coil can slide up and down, stretch out and draw back in the cavity under the action of the volume change of the water flow and the gravity of the elastic coil, and can scrape the inner wall of the outer core and/or the outer wall of the inner core, and then the water scale on the inner wall of the outer core and/or the outer wall of the inner core can be removed. Meanwhile, the flow limiting effect can be achieved, and the quality of the steam is improved.

Description

technical field [0001] The invention relates to the technical field of steam appliances, and more specifically, to a steam generator for descaling. Background technique [0002] A steam generator is a mechanical device that uses heat energy from fuel or other energy sources to heat water into hot water or steam. According to the classification of fuel, steam generators can be divided into electric steam generators, fuel oil steam generators, gas steam generators, etc. The steam generator is mainly suitable for garment factories, dry cleaners, restaurants, steamed bun shops, canteens, restaurants, factories and mines, bean products factories and other places. [0003] Steam generators are classified according to their size, and can be divided into instant steam generators and boiler steam generators. Instantaneous steam generators are small devices and are mainly used in daily life; boiler-type steam generators are generally used in industrial production, such as thermal po...

Problems solved by technology

[0005] On the other hand, after the existing steam generator is used for a period of time, the impurities in the water are converted into scale after the water is heated, and the scale is bonded in the internal flow channel and steam outlet of the steam generator

Over a long period of time, most of the surface of the heating body is covered by scale, which affects...
