Summary of the invention

The purpose of this utility model is to overcome the deficiency of above-mentioned known technology, provide a kind of reasonable in design, use reliable, leaving water temperature to reach health to drink requirement, energy-saving electric heating vacuum flask that the thermal efficiency is high.

Described energy-saving electric heating vacuum flask, comprise bottle, bottle cap, the courage of heating up water, air pressure water outlet button, electronic water outlet button, it is characterized in that: the bottom is provided with heat-generating pipe, temperature sensor, level sensor in the courage cavity of heating up water, and they all are sealedly and fixedly connected with the burning water bladder wall; The armouring sleeve pipe of temperature sensor contacts with the sleeve pipe of heat-generating pipe, and the signal output part of temperature sensor is connected with the input of the temperature controller of heating up water.Be provided with the insulation layer at the gall bladder wall of heating up water.The output control switch J1-1 of temperature controller of heating up water is serially connected between the heat-generating pipe heating wire and the communication power supply N utmost point, and output control switch J1-2 is serially connected between time controller and the dc power supply.The electrode of two mutually insulateds of level sensor is connected with the input of water level controller, and the output control switch J3-1 of water level controller is serially connected between the heating element heating wire and the communication power supply L utmost point.The output control switch J2-1 of time controller is serially connected between heating element heating wire and the commutation diode.

The utility model has the advantages that:

1, heat-generating pipe is located at the courage bottom of heating up water, the gall bladder wall of heating up water is provided with complete polyurethane thermosphere, so just prevented the loss of heat, the boiled time of the water of same capability greatly reduces, and its insulation power consumption also greatly reduces, during insulation, time controller fills the thermal inertia effect that utilizes hot water, adopt the low-power The intermittent heating, water temperature is remained on about 95 ℃, play energy-saving effect to greatest extent.

2, temperature sensor adopts occasionally PTC thermistor of the high industrial armouring integrated temperature sensor of inexpensive matter, thermoelectricity, and temperature sensor armouring sleeve pipe contacts with the heat-generating pipe sleeve pipe, and thermometric is accurate, long service life.

When 3, water temperature reaches 100 ℃, continue to change preservation and controlling automatically over to after boiled 30 seconds～1 minute, and can prevent boiled, frequently tripping operation of insulation, both guaranteed the whole fully boiled safe drinking water requirement that reaches of water, can prevent that also the heat-generating pipe burning from damaging fault.

4, level sensor is provided with height 10mm place above heat-generating pipe, can prevent anhydrous effectively or the no-water dry combustion accident.

5, the heat-generating pipe of heating up water in the courage is the single tube pattern, is convenient to daily wiping, cleaning, removal incrustation scale.

The utility model novel structure, reasonable in design, safe and reliable, its boiling water satisfies the safe drinking water requirement, good energy saving property, thermal efficiency height, the scope of application is wide.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified: among Fig. 1,2, described electric-heating thermos comprises bottle 1, bottle cap 2, the courage 3 of heating up water, air pressure water outlet button 4, electronic water outlet button 9, swivel base 16, in courage 3 chambeies of heating up water the bottom heat-generating pipe 5, temperature sensor 6 are set, the courage delivery port 10 of heating up water, level sensor 7, they all are sealedly and fixedly connected with courage 3 walls of heating up water, the armouring sleeve pipe of temperature sensor 6 contacts with the sleeve pipe of heat-generating pipe 5, and the signal output part of temperature sensor 6 is connected with the input of the temperature controller 12 of heating up water.Courage 3 outer walls are provided with insulation layer 8 heating up water.The output control switch J1-1 of temperature controller 12 of heating up water is serially connected between heat-generating pipe 5 heating wire and the communication power supply N utmost point, and output control switch J1-2 is serially connected between time controller 13 and the dc power supply.The electrode of two mutually insulateds of level sensor 7 is connected with the input of water level controller 14, and the output control switch J3-1 of water level controller is serially connected between heat-generating pipe 5 heating wire and the communication power supply L utmost point.The output control switch J2-1 of time controller 13 is serially connected between heat-generating pipe 5 heating wire and the commutation diode 15.
