According to the electric kettle disclosed by the utility model, the power supply can be automatically shut off after water is boiled, the heating can be stopped, thus the full-automatic power off can be realized, the consequences that due to the continuous work of the electric heating tube after the boiling of the water, the water quality goes bad, a fire is caused, and the like are avoided,, and the electric power is also saved.
Description
Technical field
The utility model relates to a kind of daily living article, specifically is a kind of insulating pot.
Background technology
The electrothermal tube of the insulating pot of prior art generally all is directly to connect with power line, and this insulating pot is all right when having the people to keep an eye on all the time to heat up water, and when unattended, water-in-kettle is opened and then just can not be cut off the power supply automatically; All the time seething with excitement, even the insulating pot that indicator lamp is arranged or blow a whistle, people can not remove deenergization in the time of the best; Not only wasted a large amount of electric energy, also can water quality degenerated because of water-in-kettle divides excessive evaporation; During water shortage, also can burn out insulating pot, even initiation fire.
The utility model content
The technical problem that the utility model will solve provides the insulating pot that a kind of water can be cut off the electricity supply after boiled automatically.
In order to achieve the above object, the technical scheme that the utility model provides is: a kind of insulating pot comprises kettle body, electrothermal tube, power line; The both positive and negative polarity of power line links to each other with the both positive and negative polarity terminals of electrothermal tube respectively; Also comprise the steam lead of being located in the kettle body, be connected with first bimetal release between a wherein utmost point of power line and the terminals of pairing electrothermal tube, the gas outlet of steam lead is close at the thermoinduction position of first bimetal release; The air inlet of steam lead is positioned on the maximum water level of kettle body.
After adopting technique scheme, the utility model compared with prior art has the following advantages: the utility model insulating pot is after water is boiled; Steam can advance through the air inlet of steam lead; Go out the back from the gas outlet of steam lead and contact with the thermoinduction position of first bimetal release, first bimetal release is understood automatic disconnection after experiencing the temperature of certain numerical value, and power supply cuts off automatically; Stop heating; Thereby accomplish full-automatic outage, avoided the boiled back of water electrothermal tube to work on and consequences such as the water quality brought degenerates, initiation fire, but also practiced thrift electric energy.
As improvement, be connected with second bimetal release between another utmost point of power line and the terminals of pairing electrothermal tube, the regression point of electrothermal tube is close at the thermoinduction position of second bimetal release.This structure, can not in time be cut off the electricity supply after water is boiled when first bimetal release is malfunctioning as second insurance of insulating pot, and water continues explosive evaporation.When the heater of electrothermal tube has part to surface; The temperature of the heater of electrothermal tube can continue to rise within the specific limits; This time second bimetal leaf experience after the temperature of certain numerical value can automatic disconnection; Power supply cuts off automatically, stops heating, thereby avoids the insulating pot dry combustion method and initiation fire.
Description of drawings
Accompanying drawing is the structural representation of the utility model insulating pot.
Shown in the figure, 1, the gas outlet of the air inlet 5.2 of the both positive and negative polarity terminals 5 of kettle body 2, electrothermal tube 2.1, location-plate 2.2, regression point 3, power line 4, electrothermal tube, steam lead 5.1, steam lead, steam lead 6, first bimetal release 7, second bimetal release 8, switch housing.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explain.
Shown in accompanying drawing: a kind of insulating pot; Comprise kettle body 1, electrothermal tube 2, power line 3; The both positive and negative polarity of power line 3 links to each other with the both positive and negative polarity terminals 4 of electrothermal tube respectively; The positive pole that is to say power line links to each other with the positive terminal of electrothermal tube, and the negative pole of power line links to each other with the negative terminals of electrothermal tube.Also comprise the steam lead of being located in the kettle body 15, be connected with first bimetal release 6 between a wherein utmost point of power line 3 and the terminals of pairing electrothermal tube 2.Be to be connected with first bimetal release 6 between the positive terminal of positive pole and electrothermal tube of power line in the present embodiment; The gas outlet 5.2 of steam lead is close at the thermoinduction position of first bimetal release 6; The air inlet 5.1 of steam lead is arranged on the maximum water level (figure does not mark) of kettle body 1; And have certain altitude poor with maximum water level, this difference in height can guarantee can not get into steam lead 5 along the air inlet 5.1 of steam lead after the water boiling.
In the present embodiment, automatic disconnection when the thermoinduction position of first bimetal release 6 receives more than or equal to the temperature of 75 degree.The steam that is produced during the water boiling is 100 degree, and steam can descend through steam lead 5 back temperature, finds that through repeatedly testing the back when first bimetal release 6 received the temperature of 75 degree, water was boiled.
Be connected with second bimetal release 7 between another utmost point of power line 3 and the terminals of pairing electrothermal tube 2.Be to be connected with second bimetal release 7 between the negative terminals of negative pole and electrothermal tube of power line in the present embodiment.The regression point 2.2 of electrothermal tube 2 is close at the thermoinduction position of second bimetal release 7.The both positive and negative polarity terminals 4 and the regression point 2.2 of electrothermal tube all are positioned on the location-plate 2.1 of electrothermal tube.Regression point just is arranged on a convexity on the location-plate 2.1 of electrothermal tube, and the temperature of the temperature that this is protruding and the heater of electrothermal tube is certain relation.When the heater temperature of electrothermal tube rose, the temperature of regression point also can and then rise.The temperature of heater remained on about 400 degree when electrothermal tube was normally heated up water, and the temperature of regression point (through repeatedly test, when normally heating up water, the temperature of regression point can not arrive 110 degree) about 100 degree.When first bimetal release 6 is malfunctioning, can not in time cut off the electricity supply after water is boiled, water continues explosive evaporation.When the heater of electrothermal tube 2 had part to surface, the temperature of the heater of electrothermal tube 2 can continue to rise within the specific limits, and the temperature of regression point 2.2 also can and then rise.When the temperature arrival 110 of regression point 2.2 is spent, 7 automatic disconnections of second bimetal release, power supply cuts off automatically, thereby avoids the insulating pot dry combustion method and initiation fire.First bimetal release 6 and second bimetal release, the 7 outer switch housings 8 that can play a protective role that also are provided with.
Present embodiment is for safety guarantee, and what selected for use is three-phase power line 3, and comprising cathode power supply line 3 (being live wire), anode power cord 3 (being zero line) and ground wire, ground wire directly connects shell, does not draw among the figure.
The above desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
