The first type: the oven automatically preheats, with a separate time display. To put it simply, the preset time is the time from when the machine starts working to the end (which includes the preheating time). The natural time setting is 140, fifty minutes, and then the preheating prompt sounds, and you can put food in it. , waiting for the delicious food to be cooked. This is a more common oven mode

Second: If you don’t mind the trouble, just set a time and temperature (but it should be longer than the oven’s preheating time). When it’s preheated, put the food in Go in and reset the temperature and time. You must understand that the function of preheating is to bring the internal environment of the oven to a suitable desired temperature. When the temperature is reached, the general NTC temperature probe and mechanical temperature control can detect the temperature. Then you set it for the second time. When the time comes, it will automatically skip preheating or the preheating time will be greatly shortened

Third type: reservation function + grilled food. In fact, most of the mid-to-high-end ovens on the market (mostly steam ovens) have this function. For example, before going to bed at night, you can make a reservation to automatically work after 7 hours. Then you will have something to eat when you get up in the morning. In fact, you need to read the manual for this process. When using the appointment function, many consumers thought that it was set up, but they did not expect that they only set the appointment time, but the actual working time was not set at all, or they set the working time first and then set the appointment. These are incorrect. practice.
