Description
Technical field
The present invention relates to gas appliance security protection technology, particularly relate to a kind of safety protection.
Background technology
The safe handling of indoor type domestic gas-fired water heater is the significant problem of the sector always, the accident of numerous casualties because using domestic gas-fired water heater to cause, and is all because not installing smoke exhaust pipe or the nonstandard installation of smoke exhaust pipe caused.
Gas heater operationally needs to consume a large amount of air (or oxygen O
2), the product great majority after burning in flue gas are CO
2with the CO of minute quantity.Winter operation indoor are often in relatively airtight environment, run the flue gas after burning can not be drained into outdoor once gas heater, flue gas again can enter water heater and combustion gas mixing is burnt, and reduces due to the continuous consumption of oxygen, and burning progressively becomes incomplete.Unburnt flue gas product is except CO
2to produce CO in a large number, vicious circle like this outward, indoor CO concentration constantly raises, and causes the casualty accident of indoor occupant to occur.
Occur to prevent such accident; some enterprises have employed the alarm safety device that CO alarm and gas heater link; once install the generation of the indoor generation CO of water heater; when CO gathers finite concentration (such as: 0.02%) alarm action; send sound and light alarm; and the air valve of the gas heater be attached thereto is closed, stop burning, play safeguard protection effect.But all there is life problems in any electronic product; in particular for the gas sensor that CO reports to the police; also only have 5 years by its life-span of technology best at present, and always there is certain ratio in the inefficacy of components and parts, just completely lose once CO alarm its safety protection function malfunctioning.And a large amount of implementations that are forced-ventilated or pressure supply and exhaust formula gas heater, blower fan is utilized to force the flue gas containing CO after burning effectively to drain into the outdoor generation greatly reducing water heater CO intoxication accident, as long as therefore forced-ventilated gas fast water heater correctly installs smoke exhaust pipe by specification, the CO content of water heater long-play indoor also can remain on extremely low safe range always.So can think that can not stop the poisoning generation of CO completely, its necessity is insufficient to forced-ventilated or force supply and exhaust formula gas heater to set up CO warning device.And guarantee that smoke exhaust pipe specification correctly installs to be only and thoroughly stop, because gas heater runs, the poisoning key of CO occurs.Therefore, be necessary to invent a kind of safety guard that can reflect smoke exhaust pipe exception, effectively address this problem.
