Abstract
A heat conduction structure of the electrode boiler comprises a boiler body made of heat-proof non-metal material, an electrically-heated body and a temperature controller, wherein the underside outside of the boiler body is grinded and processed into a smooth plane; the outer surface of the electrically-heated body is cut and processed into a smooth plane; and when the boiler body is placed on the electrically-heated body, the two above planes directly contact and conduct the heat. For the boiler body made of the heat-proof non-metal material of ceramic or glass and the like, the above structure is largely convenient for the grinding and the process of the underside of the boiler, reduces the process cost, and has good product interchangeability and high thermal efficiency. Moreover, the utility model radically solves the disadvantageous factor brought to the human health since using the aluminum boiler to cook the food.
Description
The utility model relates to the electric food warmer technical field, particularly a kind of electric food warmer heat conduction structure of making pot body with the heatproof nonmetal material.
Traditional automatic electric rice cooker is to adopt fine aluminium matter pot body, and its bottom manufactures dome shape, matches with the electric heating body of corresponding dome shape and realizes the heat conduction.Because the fine aluminium sheet is the fabulous material of plasticity, machinable performance is splendid, but insufficient rigidity, cooperates heat transfer with electric heating body so will be designed to spherical.Simultaneously, because aluminum metal is processed into the direct cooking food of container, can be unfavorable to health, cannot not be coated with stickingly oily technology even adopt, also can come off.Make the pot body if adopt nonmetallic materials such as heat-stable ceramic or glass, can exempt the harm to health, need be processed into smooth concave spherical surface shape but bottom of pot body will match with the protruding dome shape of electric heating body has certain difficulty, and the processing cost height, interchangeability is poor, and market is difficult to accept.The indirect thermal radiation mode of heating of existing a kind of ceramic electric heating pot system's employing, though the external bottom of pottery pot does not need grinding, heat time heating time is long, the thermal efficiency is relatively poor.
The purpose of this utility model is to provide a kind of and makes the electric food warmer heat conduction structure of pot body with the heatproof nonmetal material, and this bottom of a pan not only handling ease, processing cost is low, and with the direct thermal contact conductance of electric heating body, thermal efficiency height.
The purpose of this utility model is achieved in that a kind of electric food warmer heat conduction structure, comprise pot body, electric heating body, temperature controller that the heatproof nonmetal material is made, the outer bottom of the pot body that described heatproof nonmetal material is made is a smooth flat, described electric heating body outer surface is a smooth flat, the ceramic the bottom of a pan and the direct thermal contact conductance of electric heating body outer surface.Described heater is the heat-generating disc that buries the casting electrothermal tube.Described pot body is made by heat resisting ceramic materials or heat resistant glass material or heatproof nonmetal material.
Advantage of the present utility model is to adopt heatproof nonmetal pot body bottom surface and electric heating body planar light to slip and touches conductive structure, greatly facilitate the grinding of this bottom of a pan face, cut down finished cost, product interchangeability is good, thermal efficiency height has fundamentally solved the unfavorable factor of cooking health is brought with aluminium matter pot body.The pot body that is particularly suitable for making with heat-stable ceramic or heat resistant glass uses.
Fig. 1 is the structural representation of an embodiment of the utility model.
By following embodiment the utility model is further elaborated.
Referring to shown in Figure 1, an a kind of heat-stable ceramic electric food warmer of embodiment of the utility model heat conduction structure is by heat-stable ceramic pot body 1, bury the heat-generating disc 2, the temperature controller 3 that are cast with electric heating tube 4 and form.The 1 outer bottom grinding of heat-stable ceramic pot body is become smooth flat, the pottery pot body 1 outer bottom grinding of will generating heat becomes smooth flat, heat-generating disc 2 outer surface machining is become smooth flat, when pot body 1 is seated in heat-generating disc 2, above-mentioned two planes closely contact, the heat transfer efficiency height.During work, electric heating body 2 energisings, because temperature controller 3 contacts are in closure state (connection), so electric heating body 2 heating powers, the pan body 1 of the contact that closely cooperates with it absorbs heat.Temperature controller 3 actions when the heat that electric heating body 2 sends too high (exceed temperature controller set operating temperature value), the contact disconnects, cut off power supply, electric heating body 2 outage back temperature no longer raise, when treating that electric heating body 2 temperature are reduced to the reset temperature value of temperature controller 3, and temperature controller 3 closings of contact, electric heating body 2 evolutions of heat are given in power supply, pot body 1 absorbs, and the periodic duty that so goes round and begins again is removed to design the power of electric heating body and controlled formula by required kettle temperature value.
The utility model is made the heat conducting electric food warmer structure in the pot direct plane of body with the heatproof nonmetal material, can be widely used in the liquid heating small household electrical appliances such as ceramic electric cooker, ceramic electronic watt pot.
Claims (3)
1, a kind of electric food warmer heat conduction structure, comprise pot body, electric heating body, temperature controller that the heatproof nonmetal material is made, it is characterized in that: the outer bottom of the pot body that described heatproof nonmetal material is made is a smooth flat, described electric heating body outer surface is a smooth flat, the ceramic the bottom of a pan and the direct thermal contact conductance of electric heating body outer surface.
