Abstract
The utility model relates to an overheating resisting electric instant heater. On the basis of an ordinary electric instant heater, a temperature control device is additionally arranged and the purpose for preventing the electric instant heater from being overheated can be obtained. The temperature control device is sealed in a glass bulb and is insulated with the outside, and the safety is high. The whole temperature control device is integrated together, which is convenient for the mass production and installation. The temperature control device is connected in series with the ordinary electric instant heater, which forms the utility model. In a normal temperature, two conductor wire support frames are connected together by a bimetal slice, which forms a circuit and the electric instant heater can normally work. When water is boiled, the temperature is high, and the bimetal slice deforms and straightens, which leads the two conductor wire support frames to be disconnected, an open circuit is formed, the electric instant heater stops working and the overheating phenomenon can be avoided. After the temperature of the water descends, the bimetal slice is restored, the circuit is communicated, the electric instant heater is continuously heated, therefore the utility model can also preserve heat.
Description
Technical field
The utility model relates to immersion heater, and more particularly, the utility model relates to a kind of thermostat galvanothermy and gets soon.
Background technology
The electricity immersion heater belongs to life and uses small household appliances, and common immersion heater generally all needs the people when in use and looks after, in case the water in the water bottle boil rise after, the phenomenon of burning appears in the immersion heater work that continues, and causes danger.People need a kind of electric immersion heater that can prevent burn-off phenomenon.And present some have the patent immersion heater of this function, or pure mechanical structure, and reaction is unstable, as＜application number〉02219670 immersion heater; Or complex structure is difficult to be applied to produce, or each parts is exposed extremely dangerous outside, as＜application number〉93232284 immersion heater or the like its practical be worth little.
Summary of the invention
The purpose of this utility model designs for preventing electric immersion heater generation burn-off phenomenon, and it has overcome the defective of existing electric immersion heater on mechanism and performance.The utility model reaches the purpose that prevents burning by increase an attemperating unit on the common electrical immersion heater.This attemperating unit is sealed in the glass envelope, and is with external insulation, safe.And whole attemperating unit integrates, and is convenient to produce in batches, install.
This novel anti-burning electricity immersion heater is achieved by the following technical programs.
Its attemperating unit is to be welded on the wire support by bimetal leaf, makes in then its packaged glass being steeped.The utility model is this attemperating unit to be connected on the common electric immersion heater constitute.When normal temperature, bimetal leaf links together two wire supports, constitutes path, and electric immersion heater can operate as normal; Water boils when rising, and temperature is higher, and bi-metal plate deformed is stretched, and two wire supports are disengaged, and constitutes open circuit, and electric immersion heater quits work, thereby prevents the generation of burn-off phenomenon.After water temperature descended, bimetal leaf restored to the original state again, connected circuit and continued heating, so it also has insulation effect.
The utlity model has following advantage.
1, realizes that action accurately, can not look like other pure mechanical mechanism unstable properties.
2, this temperature control device is encapsulated in the glass envelope, with external insulation, so fail safe is good.
3, extremely simple of the utility model structure reaches same purpose, and simple than other patented technologies, cost is low, and is suitable for producing in batches.

Among the figure: plastic end cover 1 electrothermal tube 2 attemperating units 3 wire supports 4 bimetal leafs 5 glass shells 6 current-limiting resistances 7 light-emitting diodes 8 electric heating tubes 9 attemperating units 10 current-limiting resistances 11 light-emitting diodes 12 electric heating tubes 13 attemperating units 14.
Embodiment
Describe the present invention below in conjunction with accompanying drawing and example.
Outward appearance of the present utility model as shown in Figure 1, it also is equipped with attemperating unit 3 at shown position except that the plastic end cover 1 with common immersion heater, electrothermal tube 2.The structure of attemperating unit 3 as shown in Figure 2, it comprises wire support 4, bimetal leaf 5 and glass shell 6.Bimetal leaf 5 welds together with one of them wire support as shown in the figure, contacts with another support in the outside of another wire support.Whole device is encapsulated in the glass envelope 6.Its circuit connects can be as shown in Figure 3, and light-emitting diode 8 is connected with its current-limiting resistance 7; Electric heating tube 9 is connected with attemperating unit 10; Both are connected on the civil power then.Its circuit connects also can be as shown in Figure 4, and light-emitting diode 12 is connected with attemperating unit 14 with in parallel with electric heating tube 13 again after its current-limiting resistance 11 is connected at last.
In this anti-burning immersion heater insertion water, when water was normal temperature, bimetallic was in case of bending, two wire supports was connected electric heating tube feedwater heating; When water burnt boiling, the bimetal leaf temperature distortion was stretched, and two wire supports are disengaged, thereby cut off the electricity supply electric heater for heating is stopped.After water temperature descended, bimetal leaf recovered original case of bending again, connected circuit and continued heating, so it also has insulation effect.
