Abstract
The utility model discloses an electric heater which belongs to the field of heating technologies. The structure of the electric heater is that: inner tubes at upper ends of the electric heater and an outer tube at a lower end of the electric heater are assembled together; an external power line, a lead, a heating resistance wire, a thermocouple breaker and a power indicator form a closed loop; and the heating resistance wire is positioned at the bottom of the outer tube. The beneficial effects are that: the power of the electric heater is adjustable; the length of the electric heater is adjustable; a heating portion of the electric heater is concentrated at the bottom of the electric heater; and the thermocouple breaker, a whistle and the power indicator are jointly used, and thus not only the security is guaranteed, but also a user is guaranteed to timely find that water has been already boiled due to the alarm of the whistle.
Description
Technical field
The utility model belongs to technical field of heating, particularly a kind of electric heater.
Background technology
Immersion heater is small and exquisite because of its profile, low price, and firing rate is fast, and is easy to use and be widely used.The heating part of " immersion heater " normally turns to a kind of thinner metal tube, and heating wire is housed in the pipe, then pours into the insulating material of magnesia powder and so on, the heating wire encapsulation is fixed on pipe middle, and it is not contacted with tube wall.The two ends of heating wire join with power line respectively again.After the energising, electric current flows through from heating wire, and heating wire just generates heat.If " immersion heater " is immersed in the liquid, heat comes out very soon by liquid, and liquid is heated very soon, nor can burn out heating wire.
Yet immersion heater also suffers a lot of people's criticism because of dangerous property.The power of immersion heater is between 1000-2000 watt, and the heat energy of generation is all converted by electric energy, can increase the weight of the burden of circuit like this, thereby causes potential safety hazard.
In addition, existing immersion heater is once producing, outside width, and length is all finalized the design, and is difficult to work good with resident's Vessel for heating water.If immersion heater is shorter, then the shipwreck of container bottom can not be drunk to be heated; If immersion heater is longer, then the heating part of immersion heater is exposed in the middle of the air, the easy burn-out immersion heater.
The utility model content
The utility model discloses a kind of electric heater for defects.Its structure is as follows:
The inner tube of electric heater upper end and the outer tube of electric heater lower end are assembled together, and external power cord, wire, heating resistance wire, thermocouple circuit breaker and power supply indicator form loop, and heating resistance wire is positioned at the bottom of outer tube.
Described inner tube is nested with outer tube to be installed together, and the length that is nested in the inner tube in the outer tube can be regulated, and its adjustable range is the 5%-95% of outer length of tube.
The thermal insulation ceramics circle is equipped with in the bottom of described outer tube, and the thermal insulation ceramics snare is in the outside of outer tube.
Plastic housing is equipped with on the top of described electric heater, and plastic housing has hidden steam whistle, thermocouple circuit breaker and power supply indicator.
The preparation material of described inner tube is pottery.
The preparation material of described outer tube is single metal material or alloy material.
The preparation material of described heating resistance wire is Aludirome or nichrome.
The beneficial effects of the utility model are:
1) power of this electric heater is adjustable, thereby reduces the potential safety hazard that circuit causes because electric current is excessive, and relatively poor or Vessel for heating water hour can be turned down power of the present utility model when line condition.
2) length of this electric heater is variable, goes for the Vessel for heating water of more different depths, thereby the scope of adaptable container can be wider;
3) heating part of this electric heater concentrates on the electric heater bottom, and when the top short time of electric heater was exposed in the air, electric heater can not be burned, and had guaranteed safety of the present utility model and useful life.
4) thermocouple circuit breaker, steam whistle and power supply indicator are used jointly, not only can guarantee safety, and because the alarm of steam whistle can guarantee that also the user finds that in time water seethes with excitement.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of structure of electric heater is as follows: the inner tube 7 of electric heater upper end is assembled together with the outer tube 8 of electric heater lower end, external power cord 1, wire 6, heating resistance wire 9, thermocouple circuit breaker 4 and power supply indicator 2 form loop, and heating resistance wire 9 is positioned at the bottom of outer tube 8.
Inner tube 7 and outer tube 8 nested being installed together, the length that is nested in the inner tube 7 of 8 li of outer tubes can be regulated, its adjustable range is that the 5%-95%(of outer tube 7 length disregards the outer tube elbow part, the inner and outer pipes equal in length).
Thermal insulation ceramics circle 10 is equipped with in the bottom of outer tube 8, and thermal insulation ceramics circle 10 is enclosed within the outside of outer tube 8.
Plastic housing 3 is equipped with on the top of electric heater, and plastic housing 3 has hidden steam whistle 5, thermocouple circuit breaker 4 and power supply indicator 2.
Inner tube 7 can be made with heat-insulating materials such as potteries, can guarantee that plastic housing 3 is not burned, thus initiation potential.
The preparation material of outer tube 8 is single metal material or alloy material, and outer tube is 8 durable, quality is light, high temperature resistant, the capacity of heat transmission is strong thereby make.
The preparation material of heating resistance wire 9 is Aludirome or nichrome.
When external power cord 1 passed through the plug and socket place in circuit, the daily communation power supply was access in, thereby heating resistance wire 9 is started working, and at this moment, power supply indicator 2 is bright, namely showed the connection of inner heat loop.When thermocouple circuit breaker 4 is risen and generates the very high steam of temperature at water by boiling, the higher temperature of induction steam, the heating loop is cut off in automatic disconnection when then temperature reaches certain value, and power supply indicator 2 extinguishes, and guarantees that water is not dryouied, thus initiation potential.
Steam (vapor) outlet when steam whistle 5 is used for the water boiling, and a kind of alert device when boiled as water.Steam whistle 5 is as the outlet of water released vapour when seething with excitement, and steam is emitted by this outlet, and then is experienced temperature by thermocouple.Simultaneously, the steam of generation also can be blowed steam whistle, sends water to the user and has been boiled the alarm of rising.
Plastic housing 3 is mainly used in keeping the profile on the utility model top and arranging associated components, such as power supply indicator 2 and thermocouple circuit breaker 4.
Thermal insulation ceramics circle 10 places least significant end, and thermal insulation ceramics circle 10 is enclosed within the outside of outer tube 8, plays heat-blocking action.Be mainly used in preventing that immersion heater is overheated, directly contact with the Vessel for heating water bottom, also make as much as possible immersion heater reach the container bottommost simultaneously, thereby the water in the container all is heated to boiling.
