Abstract

The utility model relates to a tableware for daily life, in particular to an automatic water heater in thermos flask. The utility model uses the ordinary thermos flask (vacuum bottle) as the water heating container which has the functions of water heating and heat keeping, which achieves the purposes of low cost, power saving, and easy use. When the water is boiled, the small light is light, and the heating power is cut automatically. Even though the power is not pulled out and the water heater in the thermos flask is taken out the bottle cabinet and is arranged on the air, the utility model can not be burnt out. The utility model has the functions of automatic power-off and self-lock. The utility model is an optimum electrothermal tableware for heating the water and heating the drink in the household, the office, and the enterprise and institution.

Description

Automatic water heater in thermos flask

A kind of life boiled hydrophone of tableware Automatic thermos.

Save time, power saving, inexpensive boiled hydrophone arise at the historic moment, the boiled hydrophone of thermos flask (also being " immersion heater ") is welcome because of the easy to use and inexpensive everybody of being subjected at present, but because of no automatic control and auto-lock function, often in time do not pull out plug and damage and tired see not thoroughly, cause people again it to be produced distrust because of maloperation or after opening.

The purpose of this utility model is to provide a kind of Automatic thermos boiled hydrophone, the steam heat that takes place when boiled with water makes temperature detect switch (TDS) cut off heating current, indicator lamp is shinny simultaneously, circuit enters self-locking state, can be not different and out of control with area (height above sea level) because of environment, and after after water is opened, entering self-locking, have anti-" the empty burning " and light Presentation Function, part has overcome maloperation, reach save time, insulation, power saving, durable, safe, purpose easily.

The utility model be achieved in that the boiled hydrophone of Automatic thermos by common thermos flask (being thermos bottle again) and automatically electrical equipment two parts form.Automatically electrical equipment is by electrothermal tube, bottle stopper formula Seat for electric appliances, dicyclo chamber cover, temperature detect switch (TDS), and indicator lamp and top cover are formed.Electrothermal tube is formed the automatic control heating circuit of connecting with temperature detect switch (TDS).Be in parallel by indicator lamp, current-limiting resistance and temperature detect switch (TDS) and form water and open show circuit.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

With reference to Fig. 2 Fig. 3 and Fig. 4, electrothermal tube (6) leading-out terminal by Seat for electric appliances (5) annotate be pressed in the center, electrothermal tube outer wall earth terminal (10) connects the power line ground wire.Two electric wires of electrothermal tube connect appropriate by figure.The tapered plug of thermos in Seat for electric appliances bottom, top has two arc-shaped protrusions as steam chest screen envelope (5-1) vaporium (3-2) to be located in the inner arc of steam chest screen envelope (5-1), vaporium (3-2) top is stopped up by temperature detect switch (TDS) (3-1), the power line of electrothermal tube (6) puts insulating sleeve and draws from the breach of vaporium (3-2) bottom right, then vaporium (3-2) except that vapor opening (4) and steam pipe (4-3), seal with 704 silicon rubber on every side.The right, dicyclo chamber becomes falcate power supply wiring chamber (3-3).The outlet of steam pipe (4-3) envelope having to live distinguishes (4-2), lives in distinguishing by the work as the hinge effect and distinguish that fulcrum nail (4-1) does the horizontal axis pine and fix.Lampet (1) head stretches out on the top that is emerging in automatic control electrical equipment from the middle aperture of overhead guard (2), and overhead guard (2) links to each other with dicyclo chamber cover (3), and dicyclo chamber cover (3) links to each other with Seat for electric appliances (5), and they all use shallow tapered " push away and pull out " to connect.

With reference to Fig. 3, temperature detect switch (TDS) (3-1) is made up of (3-1-1) and bimetallic garden sheet (3-1-5) critical piece switch contact, they are middle across pallet (3-1-4), the pallet centre bore, string is placed with insulating bar (3-1-2), pallet 2 half ones respectively have shape hole, half garden, respectively put a resistance (3-1-3) in the hole, do the periphery by bakelite base and copper sheet cover (3-1-6) and become as a whole.

By accompanying drawing carefully connect the wire assemble after, thermos flask charges into cold water, make the water surface (9) from the about 5cm of bottleneck, automatically the electrothermal tube under the electrical equipment inserts in the thermos flask, and taper plug of thermos (5-2) has replaced original bottle stopper, and power line (8) plug is inserted in the supply socket, this moment, electrothermal tube just had electric current by producing electric heating water to be heated, when water boiled, steam backs down to live from steam pipe (4-3) distinguished (4-2), flows out from vapor opening (4) to vaporium (3-2) heating back.The vaporium heat is passed to bimetallic garden sheet (3-1-5) by copper sheet cover (3-1-6), make sheet former spill in garden be mutated into convex and promote insulating bar (3-1-2) and then back down switch contact right, this moment, in fact switch contact reached supply voltage to (3-1-1) two utmost points, this voltage is added on show circuit lampet (1) current-limiting resistance (1-1) and makes lampet shinny, show that water is boiled, simultaneously this voltage be added on big resistance two resistance (3-1-3) (RT) on, the electric current of this resistance of flowing through makes and produces heat and continue to make bimetallic garden sheet to become convex surface and reach the big electric current of electrothermal tube (W) the self-locking purpose of damming.If end user's this moment does not pull out power supply automatic control electrical equipment taken out from thermos flask and the charged disengaging water of electrothermal tube also can not generated heat burn out.If burn several bottles of boiling water continuously, because the auto-lock function after boiled, the lampet light yellow, reminds people will be pulled out a little while power supply the bimetal leaf concavity temperature detect switch (TDS) that rebounds is connected naturally.Therefore part has realized the empty purpose of burning of anti-misoperation.

After temperature detect switch (TDS) cuts off heating current, steam pressure reduces in the thermos flask, live and distinguish because of being subjected to gravity to cover steam port again, make whole automatic electrical equipment become a complete bottle stopper, more be incubated owing to thermos flask, therefore the boiled hydrophone of thermos flask be power saving, durable, inexpensive, be not subjected to regional influence easily, fractional energy savings is all higher than current known heater, is the best electric heating tableware of family office, enterprises and institutions' drinking water or various beverages.
