Detailed Description

The utility model is shown in figures 1-12 and comprises an outer cylinder body 1, an electromagnetic heating component 3 and a plurality of water pipes 4; electromagnetic heating assembly 3 is connected on outer barrel 1, and is a plurality of water pipe 4 is the straight tube form, and all is on a parallel with the axial setting of outer barrel 1, and is a plurality of water pipe 4 all laminates on outer barrel 1's inner wall, and with outer barrel 1 fixed linking to each other, and is a plurality of the bottom of water pipe 4 all is connected through water pump and water source, and the top all is connected with steam conduit.

When the electromagnetic heating water heater is used, water can be injected into each water pipe through the water pump, the electromagnetic heating assembly is started, so that water is heated continuously in the process of gradually rising from the water pipe, and finally steam is discharged from the top end; after accomplishing the first use, can maintain the position at outer barrel middle part with the water in the water pipe to when using next time, open simultaneously water pump and electromagnetic heating subassembly can. The steam boiler has the characteristics of high heating efficiency, instant use and no need of storing steam on the whole. Specifically, water and steam stored in the water pipe are few, and a steam chamber which is necessary in the traditional equipment is eliminated, so that the possibility of explosion of the steam chamber can be eliminated from the source; secondly, the temporary water storage is less than 30KG through the design of the size of the water pipe during actual use, so that the safety requirement of China is comprehensively met; thirdly, because the water and the steam storage quantity in the water pipe are small, the steam generating device has the advantages of high steam generating speed and instant use after being opened; and fourthly, due to the existence of the electromagnetic heating assembly, the steam heating device has the advantages of high heating speed, high steam generation speed and low energy consumption.

In addition, in consideration of practicability, the heat-insulating layer commonly used by technical personnel in the field can be wrapped outside the outer barrel body during actual use, so that water in the water pipe is not lower than 90 ℃ all the time, extra waste of energy can be obviously reduced when the equipment is stopped and restarted, steam can be rapidly generated, and the use requirement is met.

The electromagnetic heating assembly is representatively illustrated by two embodiments below:

example D1: the electromagnetic heating assembly is an electromagnetic heating coil wound by a disc, and the electromagnetic heating coil is coated outside the outer cylinder body. So as to heat the outer cylinder in the form of conventional electromagnetic heating.

Example D2: the electromagnetic heating component 3 comprises a plurality of heating units which are uniformly arranged along the axis of the outer cylinder;

the heating unit comprises a pair of containing holes 31 and a heating wire 32 which are arranged in parallel, the containing holes 31 penetrate through the outer barrel body 1 along the axial direction of the outer barrel body 1, the heating wire 32 alternately penetrates through the two containing holes 31, and a plurality of circles are wound in the two containing holes 31; the heating wires 32 in adjacent heating units are connected in series or in parallel. Thus, when the heating wire is electrified, the part between the two containing holes can be rapidly heated to form a heating unit. Because the heating wires penetrate through the two heating pipes alternately, on one hand, a heat insulation layer and a shielding layer do not need to be arranged outside the outer cylinder body again, and therefore the volume of the equipment and the manufacturing cost of the equipment are reduced remarkably; on the other hand, the heating wire does not need to be completely attached to the inner wall of the accommodating hole, and a certain gap can be reserved between the heating wire and the accommodating hole, so that the heating quantity of the heating wire is low, and the heating wire has the advantages of high safety, low energy consumption and the like.

The containment apertures are representatively illustrated by two embodiments below:

example D21, as shown in fig. 7-9: the accommodating hole 31 is a through hole formed in the outer cylinder body along the axial direction of the outer cylinder body.

Example D22, as shown in fig. 10-12: outer barrel 1 includes barrel 13, barrel two 14 and a plurality of splint 15, barrel 13 is in barrel two 14 in, and the two is with the axle center, splint 15 along the radial setting of barrel 13, and the even fixed connection of a plurality of splint 15 between barrel 13 and barrel two 14 for form between the adjacent splint 15 and hold the hole.
