摘要
以带油温过热控制装置的家用燃气灶为试验样机,参照GB 16410-2007《家用燃气灶具》第6. 12节的试验方法,选取6种不同锅具为测试样本,分别是型检试验用锅(铝锅)、能效试验用锅(铝锅且外部有碳黑镀层)、不锈钢锅、铸铁锅、陶瓷锅、带镀层不锈钢锅,测试不同样本时锅底内表面温度(即锅底温度)和锅内色拉油温度的变化情况,分析锅内色拉油深度、锅具材质、锅底厚度、锅具外表面镀层厚度对油温过热控制装置动作时锅内色拉油温度(即动作油温)的影响。阐述试验装置、试验样本选取、试验方法。试验结果表明,锅具相同的情况下,若增加色拉油深度,则锅底温度与色拉油温度间的差值增加,油温过热控制装置动作时锅底温度和动作油温均降低。当色拉油深度为10 mm时,对于型检试验用锅、能效试验用锅、铸铁锅和陶瓷锅,锅具传热能力(即吸热热流量)对动作油温的影响不大,其动作油温在263℃左右;对于不锈钢锅和带镀层不锈钢锅,其动作油温与其他4种锅具相差较大,带镀层不锈钢锅的动作油温高达278℃,不锈钢锅的动作油温仅255℃,两者相差23℃。建议设定灶具油温过热控制装置动作油温时应留有油温波动余量,避免锅具的差异导致油温过热控制装置动作油温超过标准限定值(300℃)。
A domestic gas cooking appliance with oil temperature overheating device is used as a test prototype. Referring to the test method of section 6. 12 of the Domestic Gas Cooking Appliances( GB 16410-2007),6 kinds of different pots are selected as test samples,they are type test pot( aluminum pot),energy efficiency test pot( aluminum pot with carbon black coating outside),stainless steel pot,cast iron pot,ceramic pot,stainless steel pot with coating to test the change in inner surface temperature of the pot bottom( namely temperature of pot bottom) and salad oil temperature of different samples. The influence of the depth of the salad oil in the pot,the material of the pot,the thickness of the pot bottom and the thickness of the coating of the outer surface of the pot on the temperature of the salad oil in the pot( namely the operating oil temperature) is analyzed when the oil temperature overheating control device operates. The test equipment,test sample selection and test method are described. The test results show that under the condition of the same pot,if the depth of salad oil is increased,the difference between the temperature of the pot bottom and the temperature of the salad oil is increased,and the temperature of the pot bottom and the operating oil temperature are both decreased when the oil temperature overheating control device operates. When the depth of salad oil is 10 mm,for type test pots,energy efficiency test pots,cast iron pots and ceramic pots,the heat transfer capacity of the pot( namely the heat absorption heat flux) has little effect on the operating oil temperature,which is about 263 ℃ . For stainless steel pots and stainless steel pots with coating,the operating oil temperature is significantly different from that of the other four types of pots. The operating oil temperature of the stainless steel pot with coating is as high as 278℃,the operating oil temperature of the stainless steel pot is only 255 ℃,and the difference between the two is 23 ℃ . It is suggested that the oil temperature fluctuation allowance should be left when setting the action oil temperature of the cooking appliance oil temperature overheating control device,so as to avoid the difference of the pots causing the operating oil temperature of the oil temperature overheating control device to exceed the standard limit value( 300 ℃) .
