As the further improvement of above-mentioned preferred structure, above-mentioned safe temperature controller comprises that the steam induction installation is provided with in the induction kettle body water vapour and by the live wire of deformation control electrode contact and power supply, the steam thermal sensitive piece that zero line conducts.
The utility model has following useful technique effect owing to utilized the pressure sensitive device of safe temperature controller to realize the anti-dry of kettle is protected:
The utility model safety temperature controller is by being provided with the pressure sensitive device that can detect the kettle body weight in temperature controller, when the arrival constant weight of water and kettle body and water is housed in the kettle body, the pressure front contact that is installed on kettle body bottom is upwards pressed, the pressure sensitive device utilizes catch bar pull switch device closure, thereby make when not having water or low amounts of water in the kettle body, instant cut-off, in kettle, do not stoped the further generation of dry combustion method before dryouting, the defective that has effectively prevented the overheated potential safety hazard that causes of electric hot tray and produced the incrustation scale of difficulty or ease removing has certain market popularization value.This wound is done the simple in structure of safe temperature controller, utilize that simple machinery control realizes the pressure sensitive device with being connected of switchgear, and production cost is lower.
Two pressure sensitive devices can be set in the utility model; the pressure front contact of aforementioned pressure induction installation is symmetrical arranged corresponding to the circular surfaces center line of electrode contact; kettle kettle body is formed supporting structure stably; and reach the multiple spot dynamometry, the multiple spot that forms the anti-dry of safe temperature controller detects protection.
Safe temperature controller in the utility model also is provided with the steam induction installation; when water is boiled in the kettle, produce a large amount of steam; the steam induction installation is sensed steam and the deenergization in the kettle body, together forms with the pressure sensitive device maltilevel security of kettle is protected.

Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
A kind of safe temperature controller 1 that is loaded on kettle as shown in Figure 1 and Figure 2, it is loaded on the bottom of kettle body.Safe temperature controller 1 comprises and the live wire of power supply, the electrode contact 11,12 that zero line is connected, aforementioned safe temperature controller 1 comprises support 2, be loaded in the support 2 at least one detects between the circuit of two electrode contacts 11,12 of pressure sensitive device 3, safe temperature controller 1 of kettle body weight and is provided with the switchgear of often opening 4, two silver contacts 41,42 of aforementioned switches device 4 for often opening.
Pressure sensitive device 3 comprises the pressure front contact 32 of experiencing the kettle body weight and the catch bar 31 of pull switch device 4 closures under the shake-up of pressure front contact 32.Former electrodes contact 11,12 is the circular rotary setting of 360 degree, the one side of aforementioned brackets 2 is equipped with electrode contact 11,12 and near electrode contact 12 places pressure front contact 32 is being housed, the another side of support 2 is equipped with catch bar 31, and pressure front contact 32 passes and promote under pressure catch bar 31 from the another side of support 2.
Aforementioned safe temperature controller 1 is provided with two pressure sensitive devices 3; the pressure front contact 33 of aforementioned pressure induction installation 3 is symmetrical arranged corresponding to the circular surfaces center line of electrode contact 12; kettle kettle body is formed support stably; and reach the multiple spot dynamometry, the multiple spot that forms the anti-dry of safe temperature controller 1 detects protection.
