Abstract
A dry-heating preventing device of electric kettle relates to the field of electric kettles and comprises a magnetic reed tube, wherein the magnetic reed tube stands on the bottom of a water pot of anelectric kettle, a magnetic floater which can slide upwards and downwards is sleeved outside the magnetic reed tube, and a power supply switch of the electric kettle is an interlocking switch of themagnetic reed tube. The device of the utility model can be used together with a mechanical thermo-regulator of an electro-thermal tube, intensifies the dry-heating preventing performance, and effectively protects the electro-thermal tube.
Description
Technical field
The utility model relates to the anti-dry burning device of insulating pot.
Background technology
Usually, insulating pot adopts the mechanical temperature controller that is connected to electrothermal tube to realize heating together anti-dry control.But, for calandria, mechanical temperature controller take-off by the time, the calandria temperature is too high, and this moment, electrothermal tube itself often damaged, and can only select to replace electrothermal tube, and therefore the maintenance cost height, is necessary to strengthen the anti-dry performance of electrothermal tube very much.
Summary of the invention
In order to overcome the high deficiency of anti-dry poor performance, maintenance cost of existing insulating pot, the utility model provides a kind of insulating pot anti-dry burning device that strengthens the anti-dry performance.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of anti-dry burning device of insulating pot comprises the magnetic red pipe, and described magnetic red pipe is erected at the water pot bottom of insulating pot, the outer socket of this magnetic red pipe magnetic float that can slide up and down, and the power switch of insulating pot is the linked switch of magnetic red pipe.
With respect to prior art, the beneficial effects of the utility model mainly show: can be used with the mechanical temperature controller on the electrothermal tube, realize dual anti-dry function; Strengthen the anti-dry performance of insulating pot, protected electric heating body effectively.
Description of drawings
Fig. 1 is the structure chart of anti-dry burning device of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Referring to the anti-dry burning device of Fig. 1, a kind of insulating pot, comprise magnetic red pipe 2, magnetic red pipe 2 is erected at water pot 1 bottom of insulating pot, these magnetic red pipe 2 outer sockets magnetic float 3 that can slide up and down, the power switch of insulating pot is the linked switch of magnetic red pipe 2.
The microcomputer control panel of insulating pot comprises the anti-dry control module, sends the instruction that makes the power switch interlock according to the switching information of the magnetic red pipe that receives.
Usually under the state, water is arranged in the kettle, magnetic float 3 is because buoyancy function is upwards slided, and the magnetic switch of magnetic red pipe 2 is in open mode, and power switch can normally be connected; Along with the decline of liquid level, the buoyancy that magnetic float 3 is subjected to reduces, and magnetic float 3 glides; When liquid level during near the bottom of water pot, the magnetic field of magnetic float 3 makes its magnetic switch closure near magnetic red pipe 2, and the anti-dry control module of microcomputer control panel is sent the instruction of disconnection according to this closure information to power switch.Realized the first road anti-dry control at insulating pot by the magnetic red pipe, mechanical temperature controller be installed on the heater realized the second road anti-dry control.
Claims (1)
1, a kind of anti-dry burning device of insulating pot is characterized in that: comprise the magnetic red pipe, described magnetic red pipe is erected at the water pot bottom of insulating pot, the outer socket of this magnetic red pipe magnetic float that can slide up and down, and the power switch of insulating pot is the linked switch of magnetic red pipe.
