Abstract

An electric kettle with two-stage dry-heating preventing function comprises a kettle body main body and an electro-thermal tube, wherein the electro-thermal tube is located in the kettle body main body, the electro-thermal tube is connected with a power supply switch, a mechanical type thermo-regulator for preventing dry-heating is installed on the electro-thermal tube, a magnetic reed tube and amagnetic floater which is sleeved outside the magnetic reed tube and can slide upwards and downwards are vertically installed on the bottom of the kettle body main body, and the power supply switch isan interlocking switch of the magnetic reed tube. The utility model provides an electric kettle with two-stage dry-heating preventing function, and the electric kettle with two-stage dry-heating preventing function intensifies the dry-heating preventing performance and lowers the maintenance cost.

Description

Insulating pot with secondary anti-dry function

Technical field

The utility model belongs to a kind of insulating pot.

Background technology

Generally using on the market now all is the structure of simply heating up water, and water temperature is to cut off switch to boil water by the distortion of the steam sheet of temperature controller, if temperature controller is aging, there is potential safety hazard in the switch of can not effectively cutting off the electricity supply.For heater, mechanical temperature controller take-off by the time, heter temperature is too high, and this moment, heater itself often damaged, and can only select to replace heating tube, and therefore the maintenance cost height, is necessary to strengthen the anti-dry performance of heater 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 with secondary anti-dry function that strengthens the anti-dry performance, reduces maintenance cost.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of insulating pot with secondary anti-dry function, comprise kettle body main body and electrothermal tube, described electrothermal tube is positioned at described kettle body main body, described electrothermal tube connects power switch, install on the described electrothermal tube in order to prevent the mechanical temperature controller of dry combustion method, the bottom of described kettle body main body is equipped with the magnetic red pipe vertically, be socketed in the magnetic red pipe magnetic float that can slide up and down outward, and described power switch is the linked switch of magnetic red pipe.

Magnetic float 6 is along with the variation of the water level in the water pot is moved, during near the bottom of kettle body main body, make the magnetic red pipe close (opening under the normality) at water level, judge and the power switch of control electrothermal tube disconnects, realize the first road anti-dry control, strengthened the anti-dry performance; Mechanical thermostat is set on heater has realized the second road anti-dry control.

Further, described magnetic red pipe connection line control panel, described circuit control panel comprise be used to receive the closure signal of magnetic red pipe after, send the anti-dry control module of power cutoff switch order, described anti-dry control module connects power switch.

The beneficial effects of the utility model mainly show: 1, have secondary anti-dry function, strengthened the anti-dry performance greatly; 2, reduced maintenance cost.
