Description

Off-cup detection touch mechanism

The present invention is to provide an off-cup detecting and sensing mechanism, in particular to a burner set (gas burner) disposed in a gas furnace for determining whether the pan is separated from the pan device (furnace frame) or the pot back device. The pan detection mechanism is activated.

In common cooking operations, such as stewing food, boiling soup, or boiled water, cookers are often unable to be present during cooking because of the long cooking time, if the cook is negligent due to forgetfulness or busyness. It often causes the fire to heat the pot over a long period of time, causing the water in the pot to dry out to form a state in which the pot is empty, which may cause the cooking to be burnt and unsatisfactory. In severe cases, the high temperature will burn. Cooking items, even gas, causes fires that endanger public safety.

As shown in FIG. 1 , a conventional gas furnace may be provided with an anti-air-burning device, and a temperature sensor 101 may be disposed in the burner 100 when the pan is placed on the hob (pot) 102. The temperature sensor 101 can be used to detect the temperature at the bottom of the pan, and the feedback is determined by the program of the electronic control component and the program built-in function is executed. Therefore, when the temperature of the pot is abnormally warmed up, a signal is blocked to block the gas passage, thereby preventing the occurrence of fire.

However, the anti-air-burning device of the above-mentioned conventional gas stove, the movement of the pot from the hob and the return of the hob is not easy to judge by the program, for example, the pan is taken to be cleaned, the pan is picked up and then lowered, and the temperature of the pan has a drop. Program judgment is easy to have problems. Moreover, in the process of cooking, the user often needs to move the pot with both hands, so it is difficult to switch the firepower of the gas burner while moving the pot, for example, when the pot is removed, the fire is cut. Change to a small fire to improve safety, and restore the original firepower when you return to the pot.
