Description
Technical field
This utility model belongs to the technical field of steam cleaning appliance, is specifically related to a kind of high temperature and high pressure steam generator.
Background technology
Steam clean mode has stronger cleaning, sterilizes, dissolves stain, part chemical detergent can be replaced, avoid the various side effect of chemical detergent, and economize on water very much, therefore, increasing people's Selection utilization steam is carried out (cleaning), such as, utilize steam clean automobile, furniture, greasy dirt etc..Steam washer utilizes electric energy as the energy mostly, and its core component is electric heating steam generator.Existing electric heating steam generator includes the metallic coil that layer of metal pipe is entwined, and is provided with the electrothermal tube of U-shaped in the middle of metallic coil.During work, moving the water to flow into metallic coil, current constantly contact high temperature tube wall, fully vaporization in metallic coil and become steam.
Heat in order to make electrothermal tube produce can pass to metallic coil in time, efficiently, metallic coil and electrothermal tube are all cast from a nugget genus cast-internal by people, i.e. utilizing motlten metal that metallic coil and electrothermal tube are cast one piece, metallic coil, electrothermal tube, metal casting three are cast as one.But existing said structure is only suitable for being applied to produce lower temperature, the steam of lower pressure, and is difficult to produce the steam of High Temperature High Pressure, is also unsuitable for producing the steam of High Temperature High Pressure.This is because, when vapor (steam) temperature and pressure requirements are higher, metallic coil needs have the highest temperature could become the steam of High Temperature High Pressure by water, specifically, the temperature of metallic coil typically requires and reaches more than 200 DEG C, owing to metallic coil, electrothermal tube are cast as one with metal casting, therefore metal casting is persistently heated, whole metal casting surface temperature is the highest, thus the heat passing to surrounding air is also a lot, causes bigger energy dissipation.Due to these reasons, the steam generator of existing said structure be only suitable for produce lower temperature, the steam of lower pressure, when clean to as if be relatively difficult to clean dirt (such as greasy dirt) time, the cleaning performance of the steam generator of existing said structure is not good enough.
Utility model content
The purpose of this utility model is to provide a kind of high temperature and high pressure steam generator for the above-mentioned deficiency of prior art, and it can produce high temperature and high pressure steam, and thermal losses is few.
Its purpose can be realized by below scheme: a kind of high temperature and high pressure steam generator, including metallic coil, U-shaped electrothermal tube, metal casting, metallic coil is provided with water inlet, outlet, metallic coil and U-shaped electrothermal tube and is contained in metal casting;It is mainly characterized by, and described metallic coil one has four sections, and described metal casting is correspondingly provided with four pieces, and described U-shaped electrothermal tube is correspondingly provided with four groups, and every section of metallic coil and one group of corresponding U-shaped electrothermal tube are contained in one piece of metal casting of correspondence;The shape of each piece of metal casting is cuboid and size is identical, and four pieces of metal casting arranged become the matrix pattern of two row two row;Described water inlet is positioned at the initiating terminal of first paragraph metallic coil, the whole end of first paragraph metallic coil connects the initiating terminal of second segment metallic coil, the whole end of second segment metallic coil connects the initiating terminal of the 3rd section of metallic coil, the whole end of the 3rd section of metallic coil connects the initiating terminal of the 4th section of metallic coil, and described outlet is positioned at the whole end of the 4th section of metallic coil;The internal diameter of first paragraph metallic coil is equivalent to 1.1~1.2 times of the internal diameter of second segment metallic coil, the internal diameter of second segment metallic coil is equivalent to 1.1~1.2 times of the internal diameter of the 3rd section of metallic coil, and the internal diameter of the 3rd section of metallic coil is equivalent to 1.1~1.2 times of the internal diameter of the 4th section of metallic coil.
This utility model has the following advantages and effect:
nullOne、During utility model works,Current can be heated as hot water in first paragraph metallic coil,Then in second segment metallic coil, it is heated as the mixture of hot water and steam,Completely heated up in the 3rd section of metallic coil again become steam,The last steam being just heated as High Temperature High Pressure in the 4th section of metallic coil,Visible in above process,First paragraph metallic coil、Second segment metallic coil is temperature required the highest,It is below 100 DEG C,Accordingly,First paragraph metallic coil、The temperature on the metal casting surface that second segment metallic coil is corresponding is the lowest,The temperature on the metal casting surface that the 3rd section of metallic coil is corresponding is also below the temperature on the metal casting surface of traditional structure,The temperature on the metal casting surface that the 4th section of metallic coil is corresponding is substantially equal to the temperature on the metal casting surface of traditional structure,But the surface area of the 4th piece of metal casting and volume are far smaller than surface area and the volume of the metal casting of traditional structure,Therefore,When utility model works produces high-temperature steam,By metal casting surface dispersed heat far below traditional structure;And four pieces of metal casting arranged of the present utility model become the matrix pattern of two row two row, are the most farthest close together, this more can reduce each metal casting surface directly to air dispersed heat.
Two, it is gradually reduced along water (flow) direction due to the internal diameter of each section of metallic coil, therefore it is also beneficial to stepping up of steam pressure, and the increase of gas pressure can promote the lifting of gas temperature, therefore, compared with traditional structure, this utility model is more suitable for producing the steam of High Temperature High Pressure.
