Lu Jianguo, deputy chief engineer of China Household Electrical Appliances Research Institute, said:
1, the first is direct heating, in which the electrified electric heating tube and electromagnetic tube are put into water for heating. There are some problems such as aging or damage of anti-leakage devices in use, and there are certain safety hazards.
2. The second type is indirect heating, which uses electric energy to turn a part of water into steam, and then uses the heat of steam to heat the water in the basin, thus avoiding the direct contact between the charged equipment and the water in the basin. In contrast, indirect heating is safer.
3. After a single foot bath is filled with water, it must be lifted together with the main machine, which is cumbersome and inconvenient, especially for the elderly.
4, the split foot bath tub can be taken out of the upper basin, and can be cleaned and disinfected separately, which is relatively more convenient; This design can usually be equipped with multiple upper basins, which can be replaced and is more suitable for families with large population.
To sum up, experts suggest that indirect heating and split foot bath have better effects.
