Description

Stove type off-cup detection device

The present invention relates to a hob type off-cup detecting device, and more particularly to a hob (pot setting device) installed in a gas stove for determining whether the pan is separated from the hob or returned to the hob.

In the existing common cooking operations, such as stewing food, boiling soup or boiling water, because the cooking time is longer, the cook usually cannot be present during the cooking, if the cook is negligent because of forgetfulness or busy with other things. At the same time, the furnace is often heated for a long time, and the water in the pot is dried to form a state in which the pot is air-burned, which causes the cooking to be burnt and cannot be eaten. In severe cases, the high temperature of the air will ignite. Cooking items, even gas, cause a fire and endanger public safety.

The existing gas furnace can be provided with an anti-air burning device, and a temperature sensor can be arranged in the burner head. When the pot is placed on the hob, the temperature sensor can be used to detect the temperature at the bottom of the pan, and feedback It is then judged by the program of the electronic control component and executes the built-in functions of the program. 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 air-proof burning device of the above-mentioned gas stove, the movement of the cookware leaving the hob and the returning to 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 put down, and the temperature of the pan has a drop, and the program judges Easy to have problems.

The applicant has proposed an "off-cup detection and touch mechanism" (Taiwan Patent Certificate No.: M507498), which is installed in a gas burner, and the off-cup detection touch mechanism includes: a temperature sensor, the temperature sensing device There is a sensing head, and the sensing head is disposed on the tile a burner head for contacting the bottom of the pot; a micro switch, the micro switch is disposed under the gas burner; and a linkage mechanism disposed between the temperature sensor and the micro switch The temperature sensor can activate the micro switch through the linkage mechanism. The off-cup detection trigger mechanism can be used to assist the program in determining whether the pot has left the potting device or the difficulty of returning the pot device to avoid errors. However, the off-cup detection and actuation mechanism can only be applied to a gas furnace with a temperature sensor on a gas burner, which limits its application.

In summary, the creator feels that the above defects can be improved, and he has devoted himself to research and cooperates with the application of academics, and finally proposes a design that is reasonable in design and effective in improving the above defects.

The technical problem to be solved by the present invention is to provide a hob type off-cup detecting device, which can automatically switch firepower with the movement of the pan to increase safety and convenience without relying on existing temperature sensing. The device can also assist in determining whether the pot leaves the hob.

In order to solve the above technical problems, the present invention provides a hob-type off-cup detecting device, which is mounted on a hob outside the gas burner head, and the pan detecting device includes: an actuation mechanism, the touch The mechanism is disposed on the hob; and a micro switch is disposed under the hob; when the pot is placed on the hob, the trigger mechanism can activate the micro switch to assist the program It is judged whether the pot leaves the hob or is returned to the hob.

Preferably, the trigger mechanism comprises a movable frame and a linkage rod, one end of the movable frame is pivotally mounted on the pylon, one end of the linkage rod is connected to the other end of the movable frame, and the other end of the linkage rod is adjacent to The micro switch.

Preferably, the triggering mechanism comprises a linkage rod, and the linkage rod is movably disposed on the pylon, and one end of the linkage rod is adjacent to the micro switch.

The beneficial effects of this creation: The touch mechanism of the present invention is arranged on the hob.
