Abstract
The utility model discloses a thermal temperature controller which is composed of a fixing cover, a rivet, a porcelain rod, a bimetallic strip, a fixing base, a fixed contact point, a movable contact point, a base, etc., wherein the bimetallic strip is fixed on the fixing base by the open fixing cover, the fixing base is clamped on the base, one end of the movable contact point is fixed on the base by the rivet and the other end of the movable contact point contacts the fixed contact point made of silver. When a heating element is under the condition of abnormal operation, the bimetallic strip is deformed by ballastic kick and oppresses the porcelain rod which pushes the movable contact point mode of a phosphorus copper sheet to cause the two contact points to disengage and the purpose of cutting off the power is achieved. Compared with a traditional thermal temperature controller, the utility model has the characteristics of small heat resistance, fast temperature sense, high sensitivity, etc.; the heating element in an electric kettle can be effectively protected.
Description
The utility model relates to the insulating pot Thermal temperature controller.
Insulating pot is to be subjected to one of widely used small electric apparatus in the family, have easy to use, cleaning, pollute characteristics such as few, be subjected to liking of user deeply, but there are some defectives in Thermal temperature controller in the existing insulating pot, traditional Thermal temperature controller adopts totally enclosed type, thermal resistance is big, temperature-sensitive is slow, when insulating pot Hu Shui dryout or the situation of abnormal operation such as unloaded energising under easily cause the heater element that burns out in the insulating pot.
The purpose of this utility model is that a kind of thermal resistance of design is little, temperature-sensitive is rapid, can cut off the electricity supply automatically rapidly under the abnormal operation situation, reaches the Thermal temperature controller of protection heater element.
Art designs scheme of the present utility model is: be made up of institutes such as bimetal leaf, fixed cover, holder, porcelain bar, fixed contact, movable contact, bases, fixed cover adopts Open architecture, makes the exposed heater element that also directly is contacted with of bimetal leaf.
In the middle of fixedly putting, Thermal temperature controller of the present utility model, copper sheet get into square window.
Thermal temperature controller of the present utility model, bimetal leaf is done rectangularity, thereby increases contact area, reduces thermal resistance, temperature-sensitive is rapid.
The utility model has following advantage owing to adopt such scheme than traditional Thermal temperature controller:
Thermal resistance is little, and the heat transfer temperature-sensitive is rapid, and is highly sensitive, under the heater element abnormal operation of insulating pot, makes the distortion of bimetal leaf kick, promotes the porcelain bar two contacts are broken away from, and cut off the electricity supply rapidly, thereby the protection heater element exempts from damage.
Below in conjunction with accompanying drawing embodiment of the present utility model is done detailed explanation.
Fig. 1 is the utility model Thermal temperature controller structural representation, and Fig. 2 is the fixed cover vertical view.
The utility model relates to a kind of insulating pot Thermal temperature controller, by fixed cover 1, rivet 2, porcelain bar 3, bimetal leaf 4, holder 5, fixed contact 6, movable contact 7, institutes such as base 8 form, the copper sheet fixed cover 1 that bimetal leaf 4 is got into square window by the centre is fixed on the bakelite holder 5, holder 5 is stuck on the bakelite base 8, there is a cavity at holder 5 centers, porcelain bar 3 is present in the cavity, and between bimetal leaf 4 and movable contact 7, porcelain bar 3 one ends are conflicted on phosphorus bronze sheet movable contact 7, phosphorus bronze sheet movable contact 7 one ends are fixed on the base 8 by rivet 2, silver fixed contact 6 is fixed on the base 8, when connecting power supply, heater element is under the abnormal operation situation, because bimetal leaf 4 directly contacts with heater element, the temperature-sensitive processus aboralis of being heated jump deformation promotes porcelain bar 3, and porcelain bar 3 compressing phosphorus bronze sheet movable contacts 7 break away from silver fixed contact 6, thereby cut off the electricity supply.Therefore, this Thermal temperature controller has characteristics such as thermal resistance is little, temperature-sensitive is rapid, sensitivity height, and heater element is effectively protected under the not operation situation.
Claims (3)
1, Thermal temperature controller, form by bimetal leaf (4), fixed cover (1), holder (5), porcelain bar (3), fixed contact (6), movable contact (7), base institutes such as (8), it is characterized in that the fixed cover Open architecture, make bimetal leaf (4) exposed, and direct contact heating element.
2, Thermal temperature controller as claimed in claim 1 is characterized in that getting into square window in the middle of the copper sheet fixed cover of the present utility model (1).
