Description
Technical field
The utility model relates to the linkage of a kind of linkage, particularly gas heater and vent fan.
Background technology
Gas heater can produce a large amount of harmful gases at work, as CO etc.Straight-line and chimney flue type gas heater do not force exhaust apparatus because self has, and a large amount of harmful gases of its generation constitute a threat to user's life safety.In recent years, hear the relevant intoxication accident that takes place when using gas heater to have a bath often, to be that the bathroom ventilation is bad cause its reason.If join a vent fan to straight-line and chimney flue type gas heater, with line traffic control or wireless remote control mode, both are realized interlock, when gas heater is started working, vent fan is just worked simultaneously, discharges harmful gas outdoor timely.When gas heater quits work, vent fan can delay working a period of time, remains in indoor harmful gases such as carbon monoxide when using gas heater to guarantee emptying.
A kind of water heater and vent fan linkage controller are disclosed among the Chinese patent literature CN2347116, by the electronic switching circuit that constitutes with triode BG1, resistance R 1; Outage delay circuit with electric capacity, resistance composition; Control relay circuit with triode or integrated circuit composition; Power circuit with diode, filter capacitor and transformer composition, the vent fan control circuit of forming with relay normally open contact and arc extinguishing electric capacity constitutes, each circuit connects successively, one end A of controller is connected on the normally closed contact of water heater microswitch, other end F ground connection, the two ends of relay normally open contact two ends tap vent fan switch.A kind of safety-type forced-ventilated gas water heater that and for example discloses among the Chinese patent literature CN2438050, comprise that firing circuit, start delay circuit, solenoid valve keep attraction circuit, solenoid valve start-up circuit, spark detection circuit, exhausting motor, motor delay circuit, housing, it is characterized in that: the output terminal of power supply reduction voltage circuit joins with exhausting motor and firing circuit respectively, and interchange ion sense flame circuit keeps attraction circuit with solenoid valve respectively and firing circuit joins.Above-mentioned two product structure complexity, cost cost height.
The utility model content
The purpose of this utility model aims to provide a kind of gas heater simple and reasonable, safe in utilization and the linkage of vent fan, to overcome the deficiencies in the prior art.
By a kind of gas heater of this purpose design and the linkage of vent fan, comprise water heater, vent fan and start-up circuit thereof and delay control circuit, its architectural feature is the first moving together contact KM1 that start-up circuit includes the contactor that is connected between power supply and the vent fan, draw a branch road between the first moving together contact KM1 and the power supply, branch road is connected with delay control circuit, delay control circuit includes the contactor coil of series connection, crawl Closing Switch SB2 and crawl cut-off switch SB1, crawl Closing Switch SB2 two ends are parallel with the second moving together contact KM2 of contactor, it is in parallel after the timing relay coil is connected with the 3rd moving together contact KM3 of contactor with contactor coil and crawl Closing Switch SB2, the delay switch of timing relay is connected between crawl Closing Switch SB2 and the crawl cut-off switch SB1, and gas heater is passed to contactor coil by circuit or wireless mode with control signal.
Described delay switch is its closed immediately, that outage time-delay 1～10min disconnects moving together contact of timing relay coil electricity.
Also be in series with fuse FU1, FU2 and limiting protector FR on described start-up circuit and the delay control circuit respectively.
Be in series with switch QS between described power supply and start-up circuit and the delay control circuit.
The utility model gas heater is passed to contactor coil by circuit or wireless mode with control signal, gas water heater working, the moving together contact closure of contactor in vent fan start-up circuit and the delay control circuit, vent fan and gas heater are worked simultaneously, discharge harmful gas outdoor timely; Gas heater quits work, timing relay coil blackout in the delay control circuit, and its moving together contact time-delay 1～10min (vent fan works on, and discharges residual harmful gas outdoor) back automatic cutout, vent fan just shuts down.In addition, can also work independently to the control vent fan by crawl Closing Switch SB2 and crawl cut-off switch SB1.It is simple and reasonable, the cost cost is low, easy and simple to handle, safe in utilization.
