Abstract
The invention discloses an electric kettle, which comprises a kettle body for containing water and a heating body for heating water in the kettle body, wherein the heating body is formed by sintering an inorganic nonmetallic conductive material and a carrier at a high temperature; the carrier comprises a nano ceramic material and/or microcrystalline glass. The heating body of the electric kettle is formed by sintering of the inorganic nonmetallic conductive material and the microcrystalline glass or nano ceramic material at the high temperature, and comprises a heat-conducting insulating layer, a heating layer and a thermal-insulation insulating layer, wherein the outside surface of the heat-conducting insulating layer is sintered and fixed with a layer of metal board or ceramic material. Due to the thermal-insulation action of the thermal-insulation insulating layer of the heating body, a major part of the heat generated by the heating layer in a working process is transferred to the water to be heated in the kettle body through the heat-conducting insulating layer, and thus, the heating efficiency of the product is improved, and energy conservation and environmental protection are realized. Meanwhile, the electric kettle has the advantages of high unit area heat load, small volume, uniform heating on a heat transfer surface, long service life and the like.
Description
Technical field
The present invention relates to a kind of electric kettle.
Background technology
Electric kettle is a kind of a kind of small household appliances of popularizing very much, the heating principle of at present traditional electric kettle all is the operation principle that adopts the resistance wire heating, and it is less that it has the unit are thermic load, and volume is bigger, the heating surface heating is inhomogeneous, the not high shortcoming of the thermal efficiency.
Chinese patent literature CN201578037U discloses a kind of electric kettle that adopts ceramic-metal high temperature co-firing heater element on September 15th, 2010, its heated base comprises holding and burns base plate, ceramic-metal high temperature co-firing heater element and electrode that heater element is arranged on to hold to burn on the base plate and by electrode and draws.This structure haves much room for improvement.
Summary of the invention
Purpose of the present invention aims to provide that a kind of simple and reasonable, unit are thermic load height, volume are less, the heating surface heating evenly, the electric kettle of high, the long service life of the thermal efficiency, to overcome weak point of the prior art.
A kind of electric kettle by this purpose design, comprise the calandria that is used to adorn the kettle body of water and is used for the water in the heating kettle body, its architectural feature is that heater adopts inorganic non-metallic conductive material and other carrier to make through high temperature sintering, and described other carrier comprises nano ceramic material and/or devitrified glass.
Described heater is plate-like, and it comprises the heating layer made by the inorganic non-metallic conductive material at least, is wrapped in the heat conductive insulating layer on heating layer top at least, and the heat conductive insulating layer is made by nano ceramic material and/or devitrified glass.
The bottom of described heating layer is provided with heat-insulating layer.
Described inorganic non-metallic conductive material is ceramic electronic material or rare-earth electric material, and the partiting thermal insulation material is a ceramic material.
Described heater is arranged on kettle body bottom, and the heat conductive insulating layer outer surface of heater also has been sintered to fix layer of metal plate or one deck pottery.
Described electric kettle also comprises temperature control and overtemperature protection system, power supply coupling part, and temperature control and overtemperature protection system are arranged on bottom the heater.
Electric kettle heater of the present invention becomes an integral body with devitrified glass or nano ceramic material through high temperature sintering by the inorganic non-metallic conductive material, and it adopts planar mode of heating, the gross area heating, and surface heat is even.Heater comprises the heat conductive insulating layer, heating layer and heat-insulating layer, and the outer surface of its heat conductive insulating layer has been sintered to fix layer of metal plate or ceramic material.Because the heat-blocking action of heater heat-insulating layer, the heat overwhelming majority that heating layer produces in the course of work all is dispersed in the water of kettle body domestic demand heating by the transmission of heat conductive insulating layer, thereby improves the thermal efficiency of product, reaches the purpose of energy-conserving and environment-protective.In addition, the kettle after the improvement does not need other soldering heat-generating pipe again or is bumped into heat-generating pipe pyrotoxin is provided.Advantages such as it has unit are thermic load height simultaneously, volume is little, the heating surface heating is even, long service life.
Description of drawings
Fig. 1 is one embodiment of the invention structural representation.
Fig. 2 is a heater TV structure schematic diagram among Fig. 1.
Fig. 3 is another embodiment structural representation of heater.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described.
Referring to Fig. 1-Fig. 2, this electric kettle, comprise the calandria 2 that is used to adorn the kettle body 1 of water and is used for the water in the heating kettle body, heater adopts inorganic non-metallic conductive material and other carrier to make through high temperature sintering, and described other carrier comprises nano ceramic material and/or devitrified glass.
Above-mentioned metallic plate 2.4 can be replaced by pottery 2.4 '.Above-mentioned heater 2 also may be used on electrothermal cooker tool such as water dispenser, water heater, electric cooker or other needs in the electrically heated small household appliances.
Its operation principle is: heater 2 is fixing with 1 welding of kettle body by fixed thereon metallic plate 2.4, and temperature control and overtemperature protection system 3 are fixed on heat-insulating layer 2.3 1 sides of heater 2.When starting working by power supply coupling part 4 connection power supplys, the heating layer 2.2 of heater 2 begins heating, because the heat-blocking action of heat-insulating layer 2.3, the heat of the overwhelming majority transmits in the water that is dispersed in the kettle body 1 by heat conductive insulating layer 2.1, and the thermal efficiency is improved.Add the characteristics of microcrystal glass material itself, make that heater has also that unit are thermic load height, volume are little, long service life, characteristics that the thermal efficiency is high.
