Description
Technical field
The present invention relates to a kind of electrical equipment efficiency method of testing, relate in particular to employed a kind of pan in a kind of household electromagnetic cooker efficiency test mode and this method implementation process.
Background technology
Household electromagnetic cooker utilizes electromagnetic induction principle, makes pan (magnetic conductor) in alternating magnetic field, produce eddy current, and self produces fuel factor, accomplishes electric energy to thermal power transfer.The pan self-heating reduces the intermediate link that heat transmits, and other kitchen range of its thermal efficiency ratio are high.
The issue GB21456-2008 of Chinese national standard body on February 18th, 2008 " household electrical magnetic energy is imitated limit value and efficiency grade " state compulsory standard; Wherein, The science of household electromagnetic cooker efficiency standard most critical parameters---the thermal efficiency, measurement accurately become one of important topic of improving this standard.
The method of testing of GB21456-2008 standard code is following: under specific experimental condition; At first thermometer is put into the pot center from the pot cover hole of standard pot, point for measuring temperature is 10mm apart from the bottom of a pan, starts electromagnetic stove and transfers to the peak power shelves; ℃ be heated to the scope of the temperature rise of water to the water of the certain mass in the standard pot from (15 ± 1) near (75 ± 1) K; Close electromagnetic stove at last, write down the electric flux that consumes simultaneously, and read the maximum temperature reading of mercurial thermometer in the 1min; With the energy value E of first test record serves as according to repeating said process twice again, with the mean value of three thermals efficiency as the final thermal efficiency value of this product.Above-mentioned method of testing comparatively rigorous and scientific design the method for testing of household electromagnetic cooker energy efficiency, calculate the ratio of electromagnetic stove output energy and total input energy exactly.
