The faucet is running with water, and there is usually an appliance below to catch water. Turning on the tap has the following functions: 1. It is convenient to add water with a frying spoon when cooking; 2. After a dish is fried and served, immediately rinse the wok with water and enter the cooking of the next dish. The whole process is fast and urgent, and the water can't stop. 3. If the faucet is turned off and the chef fires continuously for 30 minutes, the stainless steel countertop will be very hot until the human body touches it, and blisters will immediately appear. Pour a ladle of water on the countertop and it will turn into steam immediately with the sound! If it is summer, the chef blushes and sweats. Therefore, this continuous overflow of running water flows through the stove table to cool down. There is another more important reason. If there is no water flow, the top of the furnace will overheat, which will lead to cracking of stainless steel. When cleaning the top of the furnace before work every night, dirty water will flow from the gap to the bottom of the furnace, which is very troublesome.
Therefore, the industry usually operates cooking with the tap turned on. But the standard practice is that the fire is on and the tap is on. Turn off the fire and tap. If the stove is cooking soup, even if there is no cooking, the faucet is still on to cool down. This should be what the landlord can see.
