Abstract
The invention relates to an adjustable temperature controller comprising an insulating part I, a fixed contact piece I arranged below the insulating part I, a fixed contact piece II arranged below the fixed contact piece I, an insulating part II arranged below the fixed contact piece II, a fixed contact piece III arranged below the insulating part II, an insulating part III arranged below the fixed contact piece III, and a bimetallic piece II arranged below the insulating part III. A metal pad is arranged between the fixed contact piece I and the fixed contact piece II; and the insulating part I, the insulating part II, and the insulating part III, the fixed contact piece I, fixed contact piece II, and the fixed contact piece III, and a bimetallic piece I and the bimetallic piece II are arranged coaxially in an up-down mode. According to the invention, because one bimetallic piece is arranged based on the original temperature controller, the two bimetallic pieces can work simultaneously and a set temperature can be realized in a normal sate. Under the circumstance that the original bimetallic piece is not disconnected, the temperature rises continuously to a certain extent and then the bimetallic piece II disconnects immediately. Therefore, security of electrical equipment is improved substantially and the user experience is guaranteed.
Description
Technical field
The present invention relates to a kind of temperature controller, more particularly, to one kind can be with adjustable temperature controllers
Background technology
Temperature controller is widely used in various electrical equipments, such as electric refrigerator, water dispenser, water heater, coffee pot, microwave oven,
Air-conditioner, disinfection cabinet, electric iron etc..Temperature controller relatively conventional in the market, has substantially with Types Below：Kick type temperature control
Device, liquid rise formula temperature controller, compression-type temperature controller, electronic temperature controller, purpose digital temperature controller.Wherein bimetal leaf is as thermo-responsive
The Kick type temperature controller of reaction component is the most universal in small household appliances.Bimetal leaf is two kinds of thermal coefficient of expansions of length and width identical
The metal such as copper sheet and iron plate that differ larger are firmly combined together to be made.When being heated, copper sheet expands must be bigger than iron plate, double gold
Belong to piece just to bend to iron plate, temperature is higher, bends all the more notable over there.
Fig. 1 is the structural representation of electric iron work in prior art.During room temperature, the contact 5 of bimetal leaf 2 end points and bullet
Contact 6 on piece 1 contacts.When electric iron is connected with power supply, electric current passes through shell fragment 1, the bimetal leaf 2 contacting, stream
Cross heating wire, electrothermal wire heating simultaneously transfers heat to the metal base plate 3 of bottom, and people just can be with the metal base plate 3 of heating
Ironing clothes.When baseplate temp is increased to design temperature, bimetal leaf 2 is bent downwardly because being heated, the contact separation of contact, electricity
Road disconnects.At this moment the temperature of base plate no longer raises, and due to the radiating of base plate, temperature reduces, the deformation of bimetal leaf also gradually with
Temperature change and restPose.Go round and begin again, so that the operating temperature of electric iron is maintained at certain limit.Due to
The target of electric iron, such as material -- the difference such as cotton, fiber crops, hair, silk of medicated clothing, the operating temperature of electric iron also can be different.Logical
Often, people can adjust the knob on temperature controller, thus changing the contact pressure of shell fragment 1 and bimetal leaf 2.
The number of times recovering with bimetal leaf bending increases, and its non-recoverable deformation leading to is so that the connection of temperature controller
Angle there occurs change.Along with the frequent use of thermoregulation knob, poor contact of contacts, ablation, bonding or nonelastic, bimetallic
The non-recoverable deformation of piece can increasingly affect its normal precision using and safety.Especially in the situation that ambient temperature is relatively low
When, in the case of as subzero in Northern Europe 40 degree, temperature controller contact be often in the state that cannot disconnect so that temperature controller temperature control not
, there is quite serious potential safety hazard in standard.Therefore, the scalable improvement to temperature controller is extremely important and necessary.
