The specific embodiment

Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

Referring to Fig. 1, Fig. 2, gas heater one embodiment of the present utility model is proposed.Described gas heater comprises condensation water collection box 200, drainpipe 100, averager 300 and controller 400, wherein drainpipe 100 1 ends are communicated with condensation water collection box 200, the other end is communicated with averager 300, and condensed water just flows in averager 300 along drainpipe 100 after entering condensation water collection box 200; During circuit turn-on in controller 400, can control gas heater closes, this controller 400 detector 410 that stretches out runs through drainpipe 100 inwalls and is connected with this drainpipe 100 is inner, to survey the water level in drainpipe 100, the preferred metal bar of the detector 410 of the present embodiment, it is electrically connected to controller 400 by wire 420.When the condensate water level rising covers detector 410, will make circuit and the earth conducting in controller 400 form the loop, thereby close gas heater, for example close the burnt gas valve of gas heater, and the warning reminding user.Lasting the flowing from top to bottom of condensed water arranged in drainpipe 100 when moving due to gas heater, therefore detector 410 stretches into drainpipe 100 interior ends and can not protrude from drainpipe 100 inwalls, in order to avoid continue dirty condensed water and detector 410 conductings, cause maloperation.When drainpipe 100 is metallic conductor, also need between detector 410 and drainpipe 100 to intercept with insulating materials, cause the circuit turn-on in controller 400 after avoiding detector 410 and drainpipe 100 to electrically conduct, cause controller 400 erroneous judgements break and close gas heater; When drainpipe 100 was plastics, because plastics itself are that insulating materials can not conduct electricity, so detector 410 can directly contact with plastic drain-pipe 100.

in order to make detector 410 not only be connected but also not protrude from drainpipe 100 inwalls with drainpipe 100 is inner, the present embodiment arranges a ponding capsule 110 on drainpipe 100, its internal diameter is greater than drainpipe 100 internal diameters, detector 410 is stretched into wherein to be connected with drainpipe 100 is inner from ponding capsule 110 sidewalls, because ponding capsule 110 internal diameters are larger than drainpipe 100 internal diameters, even therefore detector 410 stretches in ponding capsule 110, also can not protrude from drainpipe 100 inwalls, thereby the condensed water that continues from top to bottom in drainpipe 100 to discharge just can not contact with detector 410, even the water droplet that spills in condensed water is stained with detector 410, circuit in also can conducting controller 400.Simultaneously, ponding capsule 110 internal diameters are larger than drainpipe 100 internal diameters, can also avoid the condensate water level rate of climb too fast and cause the air at detector 410 places to have little time to discharge, and then make condensed water can not fully touch the situation of detector 410, thereby improved the reliability of detector 410 detecting water levels.

Accordingly, the gas heater of the present embodiment, owing to having the detector 410 of surveying drainpipe 100 interior condensate water levels, when averager 300 or externally drained blockage and cause water level in drainpipe 100 to rise and when soaking detector 410, circuit in controller 400 will form the loop with the earth conducting, controller 400 will control gas heater and cut out with reminding user and keep in repair, thereby avoid gas heater to continue operation and cause condensed water immerse the gas heater internal damage and burn electronic device, improve security performance, and extended service life.

further, above-mentioned ponding capsule 110 internal diameters are more many greatly than drainpipe 100 internal diameters, just can avoid detector 410 that normal discharge of condensed water is mistaken for the water level rising that obstruction causes, for the size that reduces ponding capsule 110 to reduce costs, and further improve accuracy and the reliability of detector 410 detecting water levels, prevent its erroneous judgement and cause the gas heater of closing of controller 400 mistakes, the present embodiment also is provided with a protuberance 111 on ponding capsule 110, this protuberance 111 can be integrally formed at ponding capsule 110 and along ponding capsule 110 sidewall radial projection, also can be fixed in ponding capsule 110 sidewalls.Concrete, this protuberance 111 can be the pipeline of radial projection, this pipeline certain angle that can tilt obliquely, and normal condensed water of discharging enters pipeline to avoid from top to bottom.This pipe end seals and opens a hole of just stretching into for detector 410, overflows from this pipeline to prevent condensed water.Simultaneously, detector 410 is connected with ponding capsule 110 is inner after stretching into this protuberance 111, and does not protrude from ponding capsule 110 inwalls.Thereby the condensed water of discharging from top to bottom is more difficult to be contacted with detector 410, thereby the more difficult generation maloperation of controller 400, has improved accuracy and the reliability of detector 410 detecting water levels.

Further, described ponding capsule 110 is near condensation water collection box 200.Averager 300 or externally drained pipe are temporary transient the obstruction sometimes, thereby cause the condensate water level in drainpipe 100 to rise, and under the lasting impact and immersion of condensed water, stop up after a period of time and might automatically eliminate, and condensed water is smooth and easy discharge again.Therefore, the ponding capsule 110 that connects detector 410 is arranged on the position of close condensation water collection box 200, automatically eliminates for condensed water with the sufficient time and stop up, avoid the maloperation to temporary transient obstruction.

In addition, with reference to Fig. 3 and Fig. 4, another embodiment of gas heater of the present utility model is proposed.Be with the difference of an above-mentioned embodiment, in the present embodiment, can directly in drainpipe 100 sidewalls, protuberance 111 be set, this protuberance 111 can be wholely set with drainpipe 100 and along drainpipe 100 sidewall radial projection, perhaps be fixedly connected on drainpipe 100 sidewalls.This protuberance 111 can be the pipeline that is communicated with drainpipe 100 sidewalls, and detector 410 stretches into this protuberance 111 to be connected with drainpipe 100 is inner, and the end that its detector 410 stretches in drainpipe 100 does not protrude from drainpipe 100 inwalls.This protuberance 111 is preferably near the condensation water collection box.

Should be understood that; these are only preferred embodiment of the present utility model; can not therefore limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
