Abstract

The utility model discloses an electrical heater using steam to automatically cutting off power source, comprising a container, a container cover with a steam passage, an electrical heating tube, a temperature controller, an indicating lamp, etc. The action of bimetallic strips is triggered by using steam to make an upper and a lower contacts separate for cutting off the power source. While using the electrical heater using steam to automatically cutting off power source, if a push rod is not pressed, the two contacts can not contact each other, therefore, the energy resource can not be wasted, overheating phenomenon and liquid overflow phenomenon can not be occurred, and the trouble of people, which is caused by the phenomenon, is eliminated; the electrical heater using steam to automatically cutting off power source is free from the limit of the air pressure of areas, and a cover head can be exchanged to use as required at any time; the cost spent by users is low, and the electrical heater using steam to automatically cutting off power source is a practical heating appliance for families, institutions, schools, and enterprises and institutions.

Description

Electrical heater using steam to automatically cutting off power source

The utility model belongs to the electric heating appliance technical field.

In the electric heater of prior art about liquid, comprise the quick heater of using in beverage heater and the thermos, all be not have attemperating unit, this burns out heat-generating pipe easily under the situation that nobody looks after, and poor stability uses also inconvenient.Application number 89200417.7 temperature self-controlled electric kettles and application number 89203901.9 temperature automatically controlled warning electric kettles, its common trait all is to utilize the heat conduction of water temperature to promote the temperature control element action, contact separation is cut off the electricity supply, when water temperature reduces, can connect with the mains automatically again, it has avoided the defective of above-mentioned technology, but use this electric kettle, unplug if the user is in a hurry suddenly to leave the scene and forget, temperature control element will be worked repeatedly so, electrothermal tube work is frequent, not only waste energy, and the liquid that burns repeatedly is unfavorable to health of people, water is dryouied when serious, heater element is burnt, and this is a defective.The second, control break-make by the heat conduction of water temperature, precision is low, reason is air pressure difference, their location height above sea level difference, its water temperature of boiling is also different, cause easily with the water temperature be parameter designing temperature control element the mistake control or do not control.The 3rd, this electric kettle only uses under the prerequisite that electricity is arranged, and just can not burn as unexpected power failure, and the scope of application has limitation.

The purpose of this utility model is to provide a kind of electric heater that utilizes the automatic powered-down of steam with display unit for fear of the deficiencies in the prior art part to society, even forgotten to unplug and also can not cause energy waste, water is dryouied, heater element is burnt serious situation, the headkerchief that swaps round just can burn on other fuel, the scope of application is wider, is not subjected to territorial restrictions.

Description of drawings:

Fig. 1 is the utility model structural representation.

Fig. 2 is the A-A cutaway view of Fig. 1.

Be described in detail according to above-mentioned accompanying drawing embodiment below.

Utilize the electric heater (referring to Fig. 1, Fig. 2) of the automatic powered-down of steam, promptly utilize liquid boiling steam to reach the purpose of cutting off the electricity supply, it is achieved in that equipped container cover 11 that nontoxic heat-resisting polypropylene material is made on water container 12, and a steam channel 13 is arranged in the lid.Electrothermal tube 1 is that the different copper or aluminum material of form is made, and the power lead 2 that it passes container cover 11 and band plug joins, and lead 2 has protecting pipe 3 protections when inserting container cover 11.Be arranged in the protuberance inner chamber that container cover 11 likeness in form handle knob as the thermostat of switch, it is made up of following part in addition: an insulation shell 8 is arranged, by rivet in these housing 8 upper bottom portion flanges and support the location-plate that has groove 9 in sidewall, the ripple spring leaf 4 that is fixed with upper contact is embedded in location-plate 9 grooves, the spring leaf 15 usefulness rivets that are fixed with lower contact are on housing 8, and being mutually 90 ° of arrangements with ripple spring leaf 4, crown cap 16 is socketed in housing 8 bottoms.Be shelved with bimetal leaf 10 on the crown cap 16, in order to the lower push-rod 14 that promotes spring leaf 15 between bimetal leaf 10 and spring leaf 15 and pass housing 8 bottom holes, upper push-rod 6 in order to hand-reset passes in the housing 8 upper bottom portion holes, and can slide up and down in the hole.

The top cover 5 of band window is housed on the container cover 11, and upper push-rod 6 is bearing in top cover 5 and the location-plate 9.What be arranged in top cover 5 windows is serially connected with power switch circuit as the indicator light 7 of display unit and electrothermal tube 1 after in parallel.

In container 12, pile water during use, covered container lid 11, connect with the mains, press upper push-rod 6, upper and lower contact is connected, indicator light 7 bright explanation electrothermal tubes 1 are started working, water temperature reaches more than 95 ℃ after a quarter of an hour approximately, begins to produce steam, and the motive force of steam when steam channel 13 makes 10 actions of sensing element bimetal leaf, drive lower push-rod 14 jack-up spring leafs 15, its jack-up power makes on the groove of spring leaf 4 in the location-plate 9 and moves, and when the elastic deformation amount of ripple spring leaf 4 surpassed balance point, the elastic force of dependence itself immediately broke away from balance point, then two contact separation are promptly cut off the electricity supply, indicator light 7 is dark, electrothermal tube 1 end-of-job, and energy resource consumption stops, do not have burn-off phenomenon, do not have liquid spill.If will reburn for the second time, must the people get final product for pressing upper push-rod 6.Resetting of bimetal leaf 10 and lower push-rod 14 relies on the elastic reset of spring leaf 15 to reach.

Container 12 described in the utility model comprises kettle, thermos, thermos cup or the like, and it is better to be used for thermos, the thermos cup that can be incubated, and makes burned liquid can in time obtain insulation.If run into outage suddenly, and upper push-rod 6 is in depressed state, at this moment with the sign (not shown) on the upper push-rod 6, can judge whether liquid is boiled when using the utility model.The utility model transposing container cover 12 is changed general headkerchief promptly to be become and generally hots plate container.

Electrothermal tube 1 of the present utility model is through the electrical equipment strength test, voltage 1500V, frequency 50HZ, energising after one minute not flashover, do not puncture, leakage current is not more than 0.5 milliampere, conforms to international regulation requirement fully.

The electric heater that utilizes the automatic powered-down of steam by the utility model design, utilize steam to make the switch auto switching, energy savings, do not have burn-off phenomenon, do not have liquid spill, for people have eliminated because burning and the excessive trouble and worry of bringing, this electric heater is not subjected to territorial restrictions, applied widely, can change headkerchief at any time on demand and use, it is low that customization takes cost.
