Abstract
The utility model discloses a far-infrared electric chafing dish for an abnormity radiator, which is characterized in that a heat radiator is composed of a hollow cylinder radiator and a central heat insulating layer which is perpendicularly positioned on the disk-shaped radiator, the radius of which is bigger than that of the central heat insulating layer. The utility model has the advantages of large radiating surface, good insulating property, high thermal efficiency and power saving, and the resistance wire is entirely arranged in the radical body of the heat radiator.
Description
The utility model relates to a kind of kitchen utensils, particularly a kind of far infrared electric chafing dish.
Existing electric chafing dish adopts the pot body of middle fovea superior and the tower combustion chamber that cooperates with it, and resistance wire is wrapped on the combustion chamber, and energising back resistance wire is burnt red, and heat is played the effect of heating by the pot bulk absorption.This electric chafing dish has following two defectives: Insulation Problems often can not guarantee that the thermal efficiency is low, and power consumption is big.
The utility model provides a kind of good insulation preformance at the defective of above existing chafing dish, thermal efficiency height, the far infrared electric chafing dish that power consumption is little.
The utility model is made up of the pot body of spill on the centre and the special-shaped radiator and the pot body base of cooperation with it, it is characterized in that special-shaped radiator is made up of hollow cylinder radiator and disc radiator, hollow cylinder radiator vertical base drops on the center hole slot of external diameter than its big disc radiator, its outer wall is the far infrared coating, inwall is close to a slim radiation reflecting layer, and the center is a heat insulation layer; The hollow cylinder radiator circumferentially be evenly equipped with some through holes, resistance wire can be around wherein, disc radiator annular upper surface is the far infrared coating, far infrared coating with the hollow cylinder radiator constitutes two vertical radiating surfaces, its lower surface upper edge circumferentially has some circumferential grooves, being used for coiling resistance wire, is heat-insulation layer below the disc radiator, and all members use the screw rod by its axle center to be connected as a single entity with a pot body base.
The utility model resistance wire all coils in the matrix of radiator, so good insulation preformance has two vertical radiating surfaces, swept area is big, thermal efficiency height, and the utility model is rational in infrastructure, easy to maintenance simultaneously.
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 the utility model structural representation;
Fig. 2 abnormity radiator structure schematic diagram.
In order to make the utility model reach best effect, according to the principle that coupling absorbs, the utility model adopts enamel pan body 7, and hollow cylinder radiator 4 usefulness carborundum circumferentially are evenly equipped with some through holes 15 as matrix, and resistance wire 6 can be around wherein; Its outside wall surface is a far infrared coating 5, internal face is close to the gentle type synthetic mica pressing plate of one deck and is constituted radiation reflecting layer 3, central part has a cylinder light weight fireclay brick bar 1, inserts alumina silicate fibre insulation material 2 between bar 1 and the radiation reflecting layer 3, compound composition heat insulation layer.Disc radiator 8 is also made matrix with carborundum, its annular upper surface is a far infrared coating 13, lower surface is along circumferentially having some circumferential grooves, be used for coiling resistance wire 6, following diatomite thin type plate 11, synthetic mica laminate 12, the light weight fireclay brick pad 10 put successively of radiator 8, alumina silicate fibre insulation material 9 is filled up, compound composition heat-insulation layer to 16 of pot body bases in the bottom.Also insert insulation material in the pot body base space.14 are supply socket, and 17 is connecting screw rod.
The utility model and other chafing dish heating contrast and experiment are as follows:
Test: during the water boiling, put a certain amount of food test into
17 ℃ of room temperatures, water weigh 1700 grams, and voltage 210V adds Chinese cabbage.
1, the utility model, power 650W after the water boiling, uncapped 5 minutes, water is in fluidized state always, put into Chinese cabbage 50 grams after, water is in fluidized state again in 2 seconds.
2, traditional design electric chafing dish, power 800W uncapped 5 minutes after the water boiling, and the water boiling is poor, puts Chinese cabbage 50 grams, and water seethes with excitement for the second time in the time of 1 minute 15 seconds.
3, electric food warmer, power 650W uncapped 5 minutes after the water boiling, water boiling visibility is low, put Chinese cabbage 50 grams after, lose fluidized state in 5 minutes.
Specific heat capacity is big mutually for two kinds of electric food warmers of the utility model and other, and firing rate is fast, and the efficient height can economize on electricity more than 25%.
