Abstract

A steam generator (1) adopting a PTC semiconductor ceramic heating element as a heat source consists of an enclosure (2), a steam outlet (3), a control circuit (4), water tank (5), a heating element (6), a waterproof conduit (7), a heating temperature limiter (8), a water temperature limiter (9), a outfall (10), a temperature controller (11), a water shortage power-off contactor (12), a floater (13), a water electrifying power-on contactor (14), an entering-water pipe (15), a water intake valve (15-1) and a steam generator bracket (17). The steam generator is characterized in that the new practical heating source (6-4) is a semiconductor element packed by a ceramic element, thereby also called semiconductor positive temperature coefficient ceramic element which has a waterproof protective cover (6-2). Extracted by the wire, the heating source (6-4) is set in a shell (6-1) to form a heating element (6) which is put in the water tank (5). The heating element (6) has a heating temperature limiter (8) and the water tank (5) has floats (14) which can move freely, thereby contacting with the water electrifying power-on contactor (14). The water intake valve (15-1) is equipped at the internal top of the water tank (5) and the electrifying power-on contactor (14) is connected with the heating element (6). The steam outlet (3) communicates with the upper water tank (5), the water shortage power-off contactor (12) communicates with the lower water tank (5), and the water temperature limiter (9) is positioned inside of the water tank (5). The temperature controller (11) is controlled by the control circuit (4) and waterproof conduit (7) passes the shell (2) through the water tank (5).

Description

Adopt PTC semiconductive ceramic heat generating member to make the steam generator of pyrotoxin

Technical field the utility model relates to a kind of steam generator, particularly adopts PTC semiconductive ceramic heat generating member to make the steam generator of pyrotoxin.

The present steam generator on the market of background technology, what pyrotoxin adopted all is electrothermal tube, this electrothermal tube is short service life, fragile, generally use some months to, will burn out in 2 years, and steam generator is longer general service time, and this just means that electrothermal tube will repeatedly keep in repair and change in the use of whole steam generator.

Summary of the invention the utility model is according to the flimsy shortcoming of above-mentioned steam generator electrothermal tube, in conjunction with long-lived consideration, invented the steam generator that adopts PTC semiconductive ceramic heat generating member to do pyrotoxin, the steam generator device that provides a kind of novel PTC semiconductive ceramic heat generating member to make.

The utility model is a kind of steam generator that adopts novel pyrotoxin to make, and this PTC pyrotoxin is a kind of semiconductor element, and by the pottery parcel, external protection is a metal, can make Any shape, and the pyrotoxin that can be made into waterproof uses in water.Power can be made 100W～tens thousand of W by design, carries out customized according to the watt level needs during design steam generator.

PTC pyrotoxin volume is little, the heat generation rate height, and heating is fast, and easy burn-out not is the pyrotoxin that comes out newly developed in recent years, belongs to high and new technology.The PTC pyrotoxin is because the characteristic of internal structure, can not burn out in theory, set a peak temperature for it during fabrication, when promptly reaching the highest design temperature, the resistance value of PTC inside can increase rapidly, and electric current just reduces rapidly, and temperature just lowers at once, thereby ensured the inherently safe of PTC heater, prevented to have the possibility that burns out but still be provided with temperature limiter in the middle of actual the use.

Steam generator of the present utility model is made up of shell, water tank, steam (vapor) outlet, PTC heater, float, water intaking valve, contact-making switch, water inlet pipe, discharge outlet, temperature controller, temperature limiter, control circuit.

Technique effect of the present utility model is: 1. reach 10000 hours service life, by using every day 3 hours, the cumulative time was above 10 years; 2. need not keep in repair between the operating period; 3. thermal efficiency height, the PTC thermal source is raised to the highest at once once the energising temperature, do not resemble electrothermal tube and be that to need a period of time slowly just to be raised to the highest, so it is fast to produce steam; 4. but dry combustion method and in water, using.The PTC pyrotoxin of the utility model introduction can use in neutralize other occasion of water.Its PTC pyrotoxin and steam generator shape can design arbitrarily, select for use sheathing material unrestricted.
