Description

Temperature controllable and power-off heat preservation hot-water bottle

1st, technical field：

The present invention relates to electric kettles can realize power-off heat preservation and temperature control heating, be widely portable to family market, break Electricity heat preservation and the convenience of temperature control heating can on a large scale be used after concrete application, to need the users of different water temperatures with Power utilization environment of the convenience with safety is carried out.

2nd, background technology：

Electric kettle is exactly to keep the temperature the process developed to electric-heating water by kettle substantially, and structure is in comparison simple Some, but every electric appliance all goes out to be evolving, among the process of constantly improve, not only have in life now water it is boiled after The function of auto-power on heating and thermal insulation more adds the safe designs such as virgin lock, and such as ad hoc Amber alert formula locking closure, hommization must be protected It is safe to use to hinder user.

But common electric kettle only has water is boiled, can not realize that water opens the function of rear long-acting thermal-insulating, if needed Realize long-acting thermal-insulating, general there are two types of measures：Boiling water is transferred to vacuum flask by the first, and is held in transfer process not in place Boiling water is easily caused to splash down, pour down or forth, and due to thermos flask easily expand with heat and contract with cold (especially Summer and winter) occur explosion, spill scald thing Therefore it is very unsafe that family, which has old man and child,；Second of method is that the water cooled down is heated repeatedly, such way Bring direct result be cause water mineral precipitation, nitrite concentration it is excessively high, that is, it has often been said that thousand boiling water, to people Body has direct harm.Therefore possess it is a can "+temperature adjustment+power-off heat preservation of heating up water " insulating pot, thoroughly replace thermos flask and people Realize healthy living, a kind of environmentally protective daily behavior set an example by personally taking part.

3rd, invention content：

The present invention will be heated using PTC heating elements 4, herein on, will be for a vacuum of the design of electric kettle Double-layer stainless steel INSULATION DESIGN structure maintains a period of time for coolant-temperature gage after power-off, and devises and a pass through temperature detect switch (TDS) Carry out regulating and controlling temperature, heated in certain temperature range.In order to allow hot-water bottle that can realize above functions, us are needed to electricity The structure of hot-water bottle is redesigned.

To achieve the above object, the present invention is based on the electric kettle that steam makes bi-metal plate deformed principle, it is divided into four parts To be designed：Principle of heating setting, temperature control device setting, power-off INSULATION DESIGN, the INSULATION DESIGN of spout 1.

The operation principle of electric kettle is：It is heated using PTC heating elements 4, and the temperature of PTC thermistor is got over Height, the bigger characteristic of resistance, after water temperature reaches boiling, resistance value increases sharply, and so as to reach partition electric current, automatically powers off Function.Its power-off is not reducible, therefore kettle will not reheat automatically after powering off.

And using PTC heating elements 4, the fire hazard occurred because of dry combustion method can be effectively prevent.PTC heating elements 4 dry combustion method temperature may be set in 200 degree or so, when thermistor senses temperature soon close to set temperature, PTC element Resistance increases sharply, and electric current reduces, the power rapid decrease of heating, so as to ensure that temperature is maintained in the range of one section of safety.

PTC heating elements 4 have larger advantage for the heating of electric kettle.The heating power of electric kettle compares Small, heating duration is longer, dangerous and more using electricity, and heating duration, power consumption can be then reduced using PTC heating elements 4 Also it can accordingly greatly reduce.And due to the characteristic of itself PTC thermistor, maximum heating temperature can maintain safe range It is interior.

Power off the realization of heat preservation：Bottle body uses 8 result of double-layer stainless steel vacuum.Heat cannot transmit in vacuum 8, and heat passes Lead no medium heat-transfer.The higher grade of vacuum 8, keeps the temperature duration, and effect is better, will be evacuated skill using whole Art.Liner 3 copper facing or silver-plated can effectively form thermal insulation layer in the liner 3 of thermal insulation cup in this way, can pass through reflective thermal spoke It penetrates, effectively reduces the heat lost by heat radiation.

Boiling water heat preservation is properly termed as 0 energy consumption, and health inside power-off thermal-insulation electric heating kettle substantially.Since vacuum 8 is protected What warm electric kettle utilized is pure physics heat preservation principle, powers off after water is boiled, is protected completely by exclusive 3 inner cavity of vacuum Temperature, comparing, those are needed using chemical solids exothermic material as heat preservation donor, the electricity kept the temperature by lasting electrified regulation Hot-water bottle, electric hot water bottle are greatly saved electric energy, while PTC heating elements 4 are stored in 8 inner cavity of vacuum, further promote heating Efficiency is heated up water faster, more power saving.

The realization of temperature adjustment heating：Add a temperature detect switch (TDS) 6 on the basis of thermal-insulation electric heating kettle is powered off, then temperature detect switch (TDS) Then the coil of 6 node connection relay mixes the electric power system of other heating units, so that it may realize the control of temperature. When temperature rise is to setting value, relay cut-out circuit, electric heater is stopped, and is powered off guarantor naturally by heater element Temperature.

There are one thermoregulation knobs for electric kettle handle 7, and after setting suitable temperature, pedestal 5 begins to warm up selected It is just automatically stopped and heated after temperature, then power-off heat preservation.

As for the heat preservation of pot lid 1 and spout 2：During due to common electric heating kettle heating, temperature rise, water and air all can Expansion, normal spout 2 is through to inner cavity in addition in order to pour, in addition exactly gas leakage is depressurized.If without hole, the inside is sealed entirely It closes, the volume of air and water constantly becomes larger, and pressure will become larger, and just has the possibility of explosion.Therefore it is general in the case where this decision uses The structure of logical toothpick, hole can be opened around the removable cover of axis by being rotated when heat water, rotate work again when need to power off heat preservation when Dynamic lid, is closed hole.

4th, it illustrates：

Fig. 1 is the structure chart of temperature controllable of the present invention and power-off heat preservation hot-water bottle；

Fig. 2 is the illustraton of model of temperature controllable of the present invention and the pot lid 1 of power-off heat preservation hot-water bottle.

5th, specific embodiment：

Explanation is described in detail to the present invention below in conjunction with the drawings and specific embodiments.

The characteristics of facilitating is heated by using metal inner tube 3, the heating element of chamber installation in vacuo, heat loss is few, adds Thermal efficiency higher, more power saving of heating up water.

General heating element is replaced using PTC heating elements 4, the danger of catching fire occurred because of dry combustion method can be effectively prevent Danger.

Bottle body is all using two-level architecture, the transmission of the vacuum-energy intercept heat of inner cavity.
