Description

Automatic over-burning protector for gas stove and automatic switch for fume exhauster

The technical field is as follows: the invention relates to an automatic over-burning protection device for a gas stove and an automatic switching device for a range hood, belonging to the field of safety protection devices for gas stoves.

The background technology is that after the gas stove is used, various accidents happen, the gas stove has the problems that a valve connector leaks gas, a mouse bites through a gas pipe to leak gas, a user forgets time to cook food, and the problem that the user burns soup or even causes fire disasters happens, and the? is one of the technical schemes for solving the problems.

The invention relates to a gas stove which can automatically alarm or close a gas valve in time when the gas stove is over-burnt and gas leaks, and the gas source can be automatically closed, so that the major disasters of fire or explosion and the like caused by further development of the over-burning and the gas leaking are solved, however, how to realize the two goals? please refer to the embodiment!

The specific implementation scheme is as follows: to achieve the object of the invention, a first embodiment is characterized in that: the method comprises the following steps of adopting a commercially available finished product temperature controller assembly, installing a temperature controller on the surface of a smoke exhaust ventilator to be controlled, then electrically connecting a control circuit of the temperature controller with an exhaust fan of the smoke exhaust ventilator and a gas electromagnetic control valve of a gas stove by using conducting wires respectively, installing an induction probe of the temperature controller at the position of an air inlet of the smoke exhaust ventilator or close to the gas stove, and transmitting temperature information to the temperature controller for commanding actions after timely sensing that the gas stove generates radiant heat after ignition or generates higher radiant heat during overburning, and electrically powering on and off the gas electromagnetic valve or an alternating current contactor; the temperature of 30-60 ℃ is set as the temperature control range of the starting and the shutdown of the range hood according to the use of a user, namely the range hood is powered off and stops working when the temperature is below 40 ℃ at normal temperature, and if the temperature exceeds 40 ℃, the user needs to increase the preset temperature to exceed two temperatures of the normal temperature so as to prevent the range hood from working ceaselessly. When the probe senses the ignition of a user and the radiation temperature exceeds the preset temperature of 40 ℃ when the gas stove is used for cooking, the temperature controller can automatically make the alternating current contactor powered on to start the range hood to start oil smoke extraction, and if the user stops cooking and closes the gas stove fire, the probe of the temperature controller can automatically make the alternating current contactor powered off the power supply of the range hood to stop the oil smoke extraction because the probe of the temperature controller does not continuously sense the radiation heat at the super-normal temperature. Like this, week and rise again, realized that cooking ignition smoke ventilator just automatic start oil extraction cigarette's work, need not the manual work and open, otherwise stop the cooking and close the purpose that can realize the self-closing smoke ventilator after the stove fire, equally need not the manual work and close, solved the user and forgot or untimely switch smoke ventilator to cause the oil smoke problem of excessive and extravagant power. Is worthy of being adopted, selected, popularized and used by vast users.

The second embodiment is characterized in that: by adopting the temperature control device of the first scheme, a user presets that the temperature is within the range of 50-80 ℃, a probe of the temperature controller is arranged between two furnaces of a double-furnace end gas furnace or at the side furnace plate surface position of a single furnace end, and when the temperature controller senses overburning of the gas furnace, namely soup cooking porridge burns out water in a soup pot after overtime, the soup pot is burnt black, and even the iron pot, the aluminum pot and the tile pot are burnt to be burnt well; the temperature of the furnace is rapidly raised during the overburning, so that the heat energy radiated to the periphery is increased, and the temperature radiated by the periphery is increased, so that after the temperature control probe senses that the temperature exceeds the preset temperature, the temperature control probe immediately transmits to the temperature control system to command the electricity to enable the gas electromagnetic valve to act to close the gas source, the gas supply of the gas furnace is cut off, the furnace is flamed out, the dangerous problem that the gas furnace is overflowed continuously is automatically solved, otherwise, the gas source is automatically switched on by the automatic switch, and the normal ventilation condition is created for normal reuse.
