Description
Technical field
The invention belongs to the thermostat technical field, be a kind ofly include pedestal, stick up arm, the two-stage switch steam thermostat of link.
Background technology
Existing steam thermostat comprises pedestal, stick up arm, first electric connecting terminal, second electric connecting terminal, be arranged on the fixed touching plate on first electric connecting terminal, be arranged on second electric connecting terminal, suppress the movable contact spring that contacts with fixed touching plate under the normality situation, stick up arm and be provided with and touch the contact that movable contact spring makes it separate with fixed touching plate.Stick up arm and be arranged on the pedestal, stick up arm and be provided with reset spring part.Pedestal is provided with the temperature-sensitive bimetal leaf, temperature-sensitive bimetal leaf and stick up and be provided with head part between the arm.During work, when sticking up after arm head portion is pressed, movable contact spring contacts with fixed touching plate, forms the mains switch path.The temperature-sensitive bimetal leaf is subjected to the temperature effect of steam, produces distortion, touches head part, will stick up arm head portion jack-up, makes to stick up the arm afterbody and press down, and contact backs down movable contact spring, and it is separated with fixed touching plate, forms the mains switch open circuit.The steam thermostat of this structure has only an on off state when being used for electric kettle and being used for controlling automatically.After electric kettle is used this steam thermostat, in case the water in the kettle body by boiled, the steam thermostat is experienced steam temperature and is moved, deenergization makes the electric heater outage in the electric kettle stop heating, after this, the water in the electric kettle can slowly cool down.Make the water in the electric kettle keep stationary temperature, have only by manually, to stick up arm and press once more, movable contact spring is contacted once more with fixed touching plate, and allow electric heater switch on once more, heat, by manually, make and stick up the arm perk again, allow electric heater cut off the power supply once more, so move in circles, electric heater is formed be interrupted energising.This mode of operation keeps the constant very trouble of the hot water temperature in the electric kettle, and has limited the function expansion of electric kettle.
Summary of the invention
The object of the present invention is to provide a kind of electric kettle that is used for, utilize a cover temperature sensing device, realize main break-make automatically, auxilliary break-make manually controls, thereby realizes and can carry out the two-stage switch steam thermostat that steady temperature adds thermal control to the kettle body.
For realizing purpose of the present invention, described two-stage switch steam thermostat comprises pedestal, be arranged on the pedestal can tilting the arm that sticks up, first electric connecting terminal, second electric connecting terminal, be arranged on the fixed touching plate on first electric connecting terminal, be arranged on second electric connecting terminal, suppress the movable contact spring that contacts with fixed touching plate under the normality situation, sticking up arm is provided with and can touches the contact that movable contact spring makes it separate with fixed touching plate, be arranged on the temperature-sensitive bimetal leaf on the pedestal, be arranged on the temperature-sensitive bimetal leaf and stick up head part between the arm head portion, be arranged on the reset spring part that sticks up on the arm, on pedestal, be provided with the 3rd electric connecting terminal, on the 3rd electric connecting terminal, be provided with auxiliary fixed touching plate, be provided with the auxiliary movable contact spring that suppresses on auxiliary fixed touching plate on second electric connecting terminal, stick up between arm afterbody and the auxiliary movable contact spring and be provided with auxiliary touch part, when contact promotion movable contact spring makes it separate first section stroke with fixed touching plate, auxiliary movable contact spring and auxiliary fixed touching plate keep in touch, when contact promotes movable contact spring above first section stroke, auxiliary touch part will promote auxiliary movable contact spring makes it separate with auxiliary fixed touching plate, sticks up the fastener of arm when moving the first time at pedestal with sticking up to be provided with between the arm to block.
Owing on pedestal, be provided with the 3rd electric connecting terminal and auxiliary fixed touching plate, pedestal and sticking up is provided with between the arm to block and sticks up the fastener of arm when moving for the first time, make that sticking up arm has two sections strokes, one group of switch of every section Stroke Control causes two switches of a cover temperature sensing device control.After sticking up arm and being depressed, movable contact spring contacts with fixed touching plate, and auxiliary movable contact spring contacts with auxiliary fixed touching plate, make second electric connecting terminal respectively with first electric connecting terminal and the connection of the 3rd electric connecting terminal.Be subjected to the temperature-sensitive bimetal leaf and stick up and become and when touching head part and making its perk,, make the disconnection of second electric connecting terminal and first electric connecting terminal when sticking up arm because the barrier effect of fastener makes the afterbody that sticks up arm can only back down movable contact spring in first stroke.Again by push the afterbody that sticks up arm downwards with hand, make the afterbody that sticks up arm finish second stroke, second electric connecting terminal and the 3rd electric connecting terminal are disconnected, thereby realize making automatically second electric connecting terminal and first electric connecting terminal to disconnect, second electric connecting terminal and the 3rd electric connecting terminal are disconnected.
