The reason why Sharp's water wave furnace is slow to respond is that the temperature is too high. According to relevant information, there are more than 300 recipes to choose from in Sharp's water wave furnace, mainly steaming, roasting and frying. The water wave oven was first introduced by Sharp in Japan in 2004, and the Japanese called it superheated steam microwave oven. Superheated steam instantly heats water vapor at 100℃ to above 300℃, and its heat energy is 1 1 times that of air at 300℃ after oven heating, which is 100℃.
