Preferably, overflow pipe is cylindrical and vertical setting; Leg is cylindrical and extends vertically downward.
Preferably, electric heater has the disc heat exchanger, and heat exchanger inside has electric heating tube, and the outer bottom of heat exchanger and water container fits.
Compared with prior art, the utility model steam generator is protected equipment thereby provide to the drain passage of overflow, the appearance that can in time point out overflow faults simultaneously by excess flow protection device is set when overflow faults appears in steam generator.
Description of drawings
Fig. 1 is the internal structure schematic diagram of the utility model steam generator.
The Reference numeral that is marked in the above accompanying drawing is respectively:
The 1-housing, 2-water tank, 21-water inlet, 22-delivery port, 3-water pipe, 31-valve mandril, 32 water pipe delivery ports, 4-water container, 41-heat exchanger, 42-electric heating tube, 43-steam (vapor) outlet, 5-steam lead, 6-overflow pipe, 61-leg, 62-ventilating microhole.
The specific embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of the specific embodiment.
As shown in Figure 1, steam generator of the present utility model comprises the water tank 2 at housing 1, heater and deposit water source.Water tank is a closed structure, by water inlet 21 water fillings, after the topped up with water water inlet 21 is sealed, put into housing 1, the delivery port 22 of water tank 2 has the top-opening type valve, be connected by water pipe 3 between water tank 1 and the heater, heater is installed on the position of 2 times certain height difference of water tank, the water inlet of water pipe 3 has the push rod 31 that backs down the water tank outlet valve and is connected with the delivery port 22 of water tank, heater comprises the airtight water container 4 of heat conduction good (for example metal material) and the electric heater that fits with water container 4, electric heater has disc heat exchanger 41, heat exchanger 41 inside have electric heating tube 42, and heat exchanger 41 fits with the outer bottom of water container 4.Water container 4 is by steam lead 5 and extraneous ventilation, and electric heater forms steam by water container 4 with the evaporation of the aqueous water in the container, and the delivery port of water pipe stretches in the water container.
Further as shown in Figure 1, the inside of water container 4 also is provided with the overflow pipe 6 that is in communication with the outside, overflow pipe 6 is cylindrical and vertical setting, the water inlet of overflow pipe 6 is descending at the upper water-out mouth, the interior upper surface of the water inlet of overflow pipe 6 and water container keeps certain distance, and the water inlet of overflow pipe 6 is higher than delivery port 32 1 segment distances of water pipe.The delivery port of overflow pipe is connected with the external world, and the leg 61 that the inner upper end of water container faces down and extends cylindricality, leg 61 are cylindrical and extend vertically downward that the lower port height of leg 61 is equal to or less than the height of water pipe delivery port 32.Also be provided with the ventilating microhole 62 that connects the water container upper surface and be in communication with the outside in the leg 61 of water container, ventilating microhole 62 can provide compensated with air when overflow, avoids producing negative pressure.Overflow pipe 6, leg 61, ventilating microhole 62 have constituted the excess flow protection device of steam generator.
