Abstract

The utility model relates to a safety full automatic electric water kettle. The controlling device of the kettle comprises a normally closed thermostat which solves the problems that the thermostat which is limited by temperature can not cut off the power supply of heating tubes when the electric kettle chirps, and the normally closed thermostat is added with electric heating elements with small power, a thermostat, a moving contact and a static contact of which are normally opened, and indication lamps. The thermostats can reliably cut off the power of the heating tubes after that the electric kettle chirps. When water temperature reduce from 80 DGE C to 45 DGE C, the water is twice heated to boil, or the water can not boil when the water is twice heated. The water temperature is kept between 88 DGE and 98 DGE. The interval from stop heating to twice heating is from 1 to 3 hours, and working state can be displayed through the light and turn off of the indicating lamps. The controlling device of the utility model can also be suitable for other electric heating containers.

Description

The safety-type all-automatic electric kettle

The utility model relates to a kind of insulating pot of the usefulness that boils water.The insulating pot of Xiao Shouing has two types in the market, and a kind of is the plain edition insulating pot, and another kind is an anti-dry type insulating pot.The plain edition insulating pot interior electrothermal tube of kettle in use directly connects with power supply, can not cut off the electricity supply boiled directly only the dryouting of water, and careless slightly electrothermal tube causes blast because of water dryouies, even causes fire and personal injury accident.The electrothermal tube of anti-dry type insulating pot is controlled by a temperature controller, by the end of the electric heating pipe ring that is bent upwards, heat is conducted to temperature controller when water dryouies, and cuts off the power supply of electrothermal tube.Though the anti-dry insulating pot has overcome the hidden danger that the common electrical kettle causes when water dryouies, can only when dryouting, water could cut off the power supply of electrothermal tube, and it is careful still to need during use, otherwise can cause waste of electric energy.

The purpose of this utility model can overcome above shortcoming for providing a kind of, cuts off the power supply of electrothermal tube reliably after insulating pot pipes, when reducing, water temperature heats automatically, and the safety-type all-automatic electric kettle of energy display working condition.

Control device of the present utility model, be installed in the interlayer of kettle bottom or in the can of kettle inwall, it comprises a restriction that is subjected to temperature for the solution temperature controller, can not after piping, insulating pot cut off the power supply of electrothermal tube, and install the normally closed temperature controller (hereinafter to be referred as temperature controller K1) of a small power electric thermal element additional, be the temperature controller (hereinafter to be referred as temperature controller K2) of often opening shape with a dynamic and static contact, and indicator lamp is formed.Temperature controller K1 connects the power supply of electrothermal tube and indicator lamp under normally off.Temperature controller K2 connects the power supply of small power electric thermal element in the temperature closure of setting, and makes temperature controller K1 cut off the power supply of electrothermal tube and indicator lamp, the power supply that has also cut off temperature controller K2 simultaneously in the insulating pot back that pipes.

Embodiment below in conjunction with accompanying drawing is described describes details of the present utility model in detail.

Fig. 1 is a kind of schematic diagram of safety-type all-automatic electric kettle that cries ring insulating pot (1) assembling with bottom band interlayer.Fig. 2 is the cut-away view of often opening temperature controller (K2) of the dish-like sealed normally closed temperature controller transformation of the way.Fig. 3 is the part drawing of U type hardware, and A-A is a cutaway view.Fig. 4 is control principle figure of the present utility model, temperature controller among the figure (K1 and K2), electrothermal tube (R1), small power electric thermal element (R2), dropping resistor (R3), indicator lamp (D).Temperature controller among Fig. 1 (K1) is with the transformation of the way of flashing definite value temperature controller, for overcoming temperature controller unsettled disadvantage under big current work state, the switch sections (2) of temperature controller (K1) and bimetal leaf (5), small power electric thermal element (R2), heat conduction fixed support (6) separate and are installed in two ends and become stepped, two ends that have the strip metal member (7) of assembly hole, also can be installed in as shown in Figure 3, the upper and lower part is stepped, the bottom has a fixing hole (17) at least, and two ends of the U type hardware of assembly hole (16) are arranged at top.Temperature controller (K1) with above-mentioned strip or the assembling of U type hardware is yi word pattern or triangular form, can reliablely and stablely work under big current work attitude.For making temperature controller (K1) that the temperature controlling range of broad can be arranged, the wiring pad (3) of switch sections (2) has at least a slice to place between the dynamic and static contact elements (4).The power of small power electric thermal element (R2) is between 10W-100W, can select the import heating that reaches 700 hours service life for use, or with electrothermal alloy filament winding system, and adopt hermetically sealed technology, also can meet or exceed the import heating service life, and, do heat conduction and use with fixing with the sheet metal parcel.Temperature controller among Fig. 1 (K2) is with the anti-dress of the bimetal leaf (8) of flashing definite value temperature controller, regulates micrometer adjusting screw, dynamic and static contact (9) is often opens shape.Preferably select for use shown in figure (2), dynamic and static contact elements (15) is at the dish-like sealed temperature controller (K2) of often opening of 95 ℃ of-99 ℃ of closures of water temperature, bakelite receptacle among Fig. 1 (11) has indicator lamp wire casing (13), indicator lamp jack (12) and metal ground strip (14).Also can set up the preventing dry combustion function, promptly in the end of electrothermal tube (R1) ring, with a heat conduction member (10) with at the bottom of temperature controller (K1), electrothermal tube (R1) are fixed on kettle by dress.

After assembling on line by Fig. 1 and Fig. 4, when 95 ℃-99 ℃ of water temperatures, transfer thermostat (K2), regulate temperature controller (K1) to opening in the insulating pot back that pipes to closed.

So far, the utility model can be reliablely and stablely cuts off the power supply of electrothermal tube (R1) in the insulating pot back that pipe, and fall in water temperature and heat once more to the water boiling when ending 80 ℃-45 ℃, or water no longer seethes with excitement when heating once more, and water temperature remains between 88 ℃-98 ℃.Heat from stopping to be warmed to once more, can be at interval 1-3 hour, and the light on and off by indicator lamp shows and heats or stop to heat, and reached safety and purpose of energy saving.Its control device also is applicable to the electric-heating container of other water.
