Automatic overflow test device The overflow test is an important test item in the home appliance safety standard. It requires to simulate the phenomenon of liquid overflow in household appliances such as electric kettles, slow cookers, rice cookers, etc. in daily use, and the standard only stipulates that it should not exceed 5 The inclined plane of °° and the inclined plane of 20° "continuously inject into the container for one minute", the details of how to inject, the rate of injection and other details are not mentioned, which makes the operator have great arbitrariness in the test, and it is also a long-term laboratory. An uncertain test content.

 This device is suitable for the safety test of IEC60335-1:2000 household and similar electrical appliances: the detection of Chapter 15. Moisture Resistance Clause 15.2, IEC60335-2-24 and other standards, is an ideal auxiliary testing equipment for professional testing institutions and manufacturers. Fill the liquid container of the appliance with saline containing about 1% NaCL, and then use 15% of the container's capacity, or 0.25L of excess saline of the same concentration, whichever is larger, and pour it into the container stably in 1 minute . The appliance shall then be subjected to the electric strength test of 16.3, and the visual inspection shall show that there are no traces of water on the insulation that can cause the creepage distance and clearance to fall below the limits specified in 29.1.

   This equipment meets the requirements of Clause 15.2 of the GB4706.1-2005 standard and the test requirements of GB4706.19 and GB4706.30. It can test with 1% sodium chloride solution (15% of the container capacity, or 0.25L of the same concentration solution) within 1min. , The larger of the two) is evenly poured into the container of the tested appliance. When the liquid heater is used for moisture resistance test, the structure of the inspection product will accidentally splash water out of the container during normal use and operation. Or the water in the container is too full, and the water will boil and overflow when the power is turned on. Is it possible to ensure that the overflowing water does not affect their electrical insulation performance?
