Abstract

The utility model relates to an automatic-control electric-heating kettle which is formed by additionally be provided with an automatic controller which is composed of a temperature sensing probe, an electromagnet, a button, a reed switch, a permanent magnet, etc. On the basis of the existing electric-heating kettle. The utility model has the advantages of simple structure, low cost and high self-control ability and can better protect a heating tube from damaging. Meanwhile, the electricity-saving effect is also very obvious.

Description

Automatic-control electric-heating kettle

The utility model belongs to daily electric heater.

The electric kettle of people's use at present is because the restriction of itself structure, when water is boiled in the kettle, must the very important person remove deenergization, otherwise will waste electric energy in vain even electrification will take place to use, time one is long simultaneously, along with evaporation of water,, also will burn out heating element when water level drops to when exposing heat-generating pipe.

The purpose of this utility model is to overcome the shortcoming of existing electric kettle, provide a kind of simple in structure, cost is low, electric kettle with self-control so that saves energy, the protection electric kettle.

Main points of the present utility model are at automatic controlled box of the other installation of the supply socket of existing electric kettle, a knob that has contact switch is arranged on the automatic controlled box, kettle body and covering of pot lid at kettle are located temperature-sensing probe of peristoma external stability, have a kettle exhaust outlet on pot lid or the kettle body, temperature-sensing probe is parallel relative with the kettle exhaust outlet, electromagnet in temperature-sensing probe and the automatic controlled box is connected, by leading to of temperature-sensing probe control electromagnet power supply, break, and then control the break-make of heat-generating pipe power supply by electromagnet armature from the action of locking bolt control knob.

Following accompanying drawing provides an embodiment of the present utility model:

Fig. 1 is a self-controlling electrothermal kettle profile schematic diagram

Fig. 2 is the controlling organization partial sectional view

Fig. 3 is the automatic controls schematic diagram

Fig. 4 is the control system electrical schematic diagram

The embodiment that provides below in conjunction with accompanying drawing does detailed description to the utility model:

A kind of self-controlling electrothermal kettle, comprise the kettle body, pot lid, handle, power input socket, several parts such as heat-generating pipe, the utility model is equipped with an automatic controlled box on power input socket (1) side, knob (3) is arranged on the automatic controlled box, close place's peristoma external stability installation temperature-sensing probe (2) at kettle body and pot lid, have a kettle exhaust outlet (15) on pot lid or the kettle body, temperature-sensing probe (2) is parallel relative with kettle exhaust outlet (15), temperature-sensing probe (2) is connected with electromagnet (11) in the automatic controlled box by electric wire, one contact switch (9) is arranged on the knob (3), contact switch (9) one ends connect power supply, the other end connects electromagnet (11) and heat-generating pipe (8), knob (3) is connected with the box wall of automatic controlled box by knob top spring (14), the armature that moves through electromagnet (11) of knob (3) is from locking bolt (10) control, and the other end of temperature-sensing probe (3) is connected with another input of power supply.

The bimetal leaf (13) and a microswitch (12) of a temperature-sensitive are arranged in the temperature-sensing probe of the present utility model (3), and the on-off action of microswitch (12) is controlled by bimetal leaf (13).

When being lower than heat-generating pipe (8) electric kettle is cut off the power supply automatically for water level in kettle, the utility model has a float (5) contiguous with automatic controlled box in the kettle body, a permanent magnet (6) is arranged in the float (5), a tongue tube (7) in parallel with temperature-sensing probe (2) is arranged in the automatic controlled box, and the switching action of tongue tube (7) is controlled by permanent magnet (6).

For making electric kettle can reflect the switching situation of power supply intuitively, the utility model is equipped with an electromotion pilot lamp (4) on automatic controlled box, and electromotion pilot lamp (4) one ends link to each other with electromagnet (11), and the other end links to each other with temperature-sensing probe (2).

Operation principle of the present utility model is as follows:

When adding the water of q.s in the kettle, plug in, press knob (3), electromotion pilot lamp (4) is bright, circuit is connected water is heated, simultaneously armature from locking bolt (10) with knob (3) self-locking, when water was boiled, steam was discharged from kettle exhaust outlet (15), made temperature-sensing probe (2) heating, bimetal leaf (13) opens and promotes microswitch (12) closure, electromagnet (11) energising attracts armature from locking bolt (10) action and release button (3), and knob (3) resets under knob top spring (14) promotes contact switch (9) is disconnected, stop power supply, electromotion pilot lamp (4) extinguishes.

When anhydrous in the kettle or water level are lower than heat-generating pipe (8), float this moment (5) falls to making permanent magnet (6) and tongue tube (7) to be in same horizontal level, because the effect of permanent magnet (6) will make tongue tube (7) connect, this moment is if connect power supply and press knob (3), electromagnet (11) will form the closed-loop path energising by the tongue tube lines, attract armature from locking bolt/(10) knob (3) to be resetted, switch contacts disconnects, and circuit cuts off the power supply automatically.

The utility model is simple in structure, and cost is low, self-control is strong, can protect preferably heat-generating pipe to exempt from damage, and energy-saving effect is also comparatively obvious simultaneously.
