The invention provides an insulating electric kettle. The kettle comprises a kettle body, heating elements, a water boiling heating circuit and an insulation heating circuit, wherein the heating elements are connected in the water boiling heating circuit in series; the insulation heating circuit comprises a kick type temperature controller and a PCB board for controlling power of the heating elements, which are connected in series; and the heating elements are simultaneously connected in the insulation heating circuit in series, so that heating elements simultaneously have functions of water boiling heating and insulating. The kettle reduces power when a heating tube works by utilizing the characteristic of the PCB board, or power reduction on the PCB board can be set into an adjustable mode, thereby realizing insulation of water in different capacities. The kick type temperature controller is an automatic reset temperature controller, and the operating temperature of the controller can be set according to requirement of different users so as to realize controllable water temperature. The insulating electric kettle has the advantages of simple and reasonable structure, high heat utilization rate, low cost, wide application range (such as households, hotels, tea houses and the like), and is applicable to mass production.

Description

Thermal-insulation electric heating kettle
Technical field
The present invention relates to a kind of thermal-insulation electric heating kettle.
Background technology
Low-power insulation kettle is as a kind of popular small household appliances, in the prior art, its heat preserving mode mainly contains two kinds: a kind of is that the heat-generating disc of insulating pot is provided with two strip materials, structure is same or similar with two heating tubular types, but the different heat-generating pipe of power, article one, it is to boil water to play heating, another insulation effect, this kind structural disadvantages are that the power that is incubated is too big, and heat retaining and exothermal pipe difficulty of processing is big, complex process, the cost height; Heat-generating pipe of another kind of use and PTC combination are incubated, and heat-generating pipe is used for heating to boil water, and PTC is used for being incubated.This kind structure PTC must be installed on the heat-generating disc, has strengthened the kettle overall volume, can not satisfy the requirement of client to product appearance, the production cost height.
A kind of thermal-insulation electric heating kettle is disclosed among the China Patent No. ZL200720050194.1, comprise pot lid, kettle body, Hu Zui, heating chassis and base, wherein be provided with the insulation sheet in the thermal-insulation electric heating kettle, kettle body surface is provided with a control panel, control panel is provided with heater switch and insulation switch, heater switch is electrically connected with the heating chassis, and the insulation switch is electrically connected with the insulation sheet.The electric kettle of this structure adopts heating chassis and two kinds of heating element heaters heating of insulation sheet, improves production cost greatly, and complex structure, volume are big.
Summary of the invention
Purpose of the present invention aim to provide a kind of simple and reasonable, cost is low, insulation power low thermal-insulation electric heating kettle, to overcome weak point of the prior art.
A kind of thermal-insulation electric heating kettle by this purpose design, comprise kettle body, heater element, heating circuit to boil water and heat tracing circuit, heater element is connected in the heating circuit to boil water, its architectural feature is that the heat tracing circuit comprises the Kick type temperature controller of mutual series connection and the pcb board of control heater element power, heater element is connected in the heat tracing circuit simultaneously, makes heater element have the effect that heating is to boil water and be incubated simultaneously.
Described heat tracing circuit, heater element and heating circuit to boil water are encapsulated in the kettle body bottom by pot bottom; Heater element is heat-generating pipe or PTC heater, and the heat-generating pipe end face is provided with heat-generating disc, and heat-generating disc and kettle body bottom are tightly connected; Kick type temperature controller is adjacent to and is arranged on heat-generating disc or the kettle body.
Also be in series with the insulation switch on the described heat tracing circuit, the corresponding insulation of pot bottom sidepiece switch is provided with the insulation shift knob that joins with it.
Described heating circuit to boil water comprises steam cock and the heater switch that is connected on the temperature controller, and heater switch is connected on the heating circuit to boil water, joins with steam cock.
The present invention utilizes the characteristic of pcb board, the power when reducing heat-generating pipe work, perhaps, fall on the pcb board power also can be arranged to adjustable, thereby realize the insulation of different capabilities water.Kick type temperature controller is the temperature controller that automatically resets, and its operating temperature can be set according to the needs of different user, to realize controlled water temperature.It is simple and reasonable, heat utilization efficiency is high, cost is low, accommodation very wide (as family, hotel and tea art house etc.), help a large amount of productions.
Description of drawings
Fig. 1 is one embodiment of the invention structural representation.
Fig. 2 is circuit theory diagrams of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described.
Referring to Fig. 1, this thermal-insulation electric heating kettle comprises kettle body 1, heat-generating pipe 7, heating circuit to boil water and heat tracing circuit, and heat-generating pipe is connected in heating circuit to boil water and the heat tracing circuit simultaneously.Heat tracing circuit, heat-generating pipe 7 and heat circuit to boil water and be encapsulated in kettle body 1 bottom by pot bottom 8, the heat-generating pipe end face is provided with heat-generating disc 2, is tightly connected bottom heat-generating disc and the kettle body.The heat tracing circuit comprises the Kick type temperature controller 5 of mutual series connection and the pcb board 4 of control heat-generating pipe power, and Kick type temperature controller is adjacent to and is arranged on the heat-generating disc.Pot both sides, bottom 8 front and back are respectively arranged with insulation shift knob 3 and heater switch 9.Heat circuit to boil water and comprise steam cock and the heater switch 9 that is connected on the temperature controller 6, heater switch is connected on the heating circuit to boil water, joins with steam cock.
Be parallel with insulation indicator lamp and indicator lamp to boil water 10 respectively on above-mentioned heat tracing circuit and the heating circuit to boil water, indicator lamp to boil water is arranged near the heater switch 9.
Its operation principle is: referring to Fig. 2, when to boil water, open heater switch K, indicator lamp L1 is bright, heat-generating pipe R begins heating, when the water in the insulating pot when seething with excitement, the steam cock Q action on the temperature controller drives heater switch K take-off, function to boil water is finished in the entire circuit outage, and indicator lamp L1 goes out.If need insulation this moment, promptly open insulation switch S 1, indicator lamp L2 bright (this moment since kettle in water temperature than Kick type temperature controller KSD tripping temperature height, so the Kick type temperature controller KSD of this moment is in off-state, indicator lamp L2 is bright), when water temperature in the kettle drops to when lower than the tripping temperature of Kick type temperature controller KSD, Kick type temperature controller KSD begins auto-closing, indicator lamp L2 goes out, heat-generating pipe R falls by pcb board after the power, and beginning is with the low-power heating, and water temperature rises, when water temperature is raised to tripping temperature than Kick type temperature controller KSD when high, Kick type temperature controller KSD begins automatic tripping, and indicator lamp L2 is bright, so circulation, the break-make of Kick type temperature controller realizes the duty of heat-generating pipe, thereby realizes the heat insulation function of kettle.
