Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model principle schematic.
The specific embodiment
Below with reference to Fig. 1 and Fig. 2 specific embodiment of the utility model is elaborated.
Fig. 1 is the concrete structure schematic diagram of the utility model embodiment; gas heater comprises gas heater main frame 10 among the embodiment; monitoring alarm 20 and energy supply control module 30; wherein; monitoring alarm 20 and gas heater main frame 10 independent settings; monitoring alarm 20 can be monitored indoor fuel gas content and temperature simultaneously; energy supply control module 30 connects gas heater main frame 10 and monitoring alarm 20; when monitoring alarm 20 monitors indoor fuel gas content or temperature exceeding standard; energy supply control module 30 cuts off the general supply of gas heater main frame 10 by force when reporting to the police, the protection of shutting down.
Comprise CH in the fuel gas that gas heater adopts in the present embodiment
4And CO, monitoring alarm 20 can be simultaneously to indoor CH
4Monitor simultaneously with two kinds of fuel gas of CO, if gas heater leaks air or other faults cause indoor CH
4With content value of being above standard at least a among the CO, then monitoring alarm will send alarm signal; Simultaneously, monitoring alarm is also monitored environment temperature, and when the environment temperature value of being above standard, monitoring alarm can send alarm signal equally.When reporting to the police, energy supply control module 30 can cut off the general supply of gas heater main frame 10 by force, gas heater is forced to shutdown, thereby avoid in the indoor environment because the leakage of combustion gas further improves indoor CH4 and CO content, thereby avoid taking place user's person or the damnous accident of property.
Monitoring alarm 20 can recording room in the data of fuel gas content or temperature, the user can check stored data message, by reading stored data message and then analyzing and use, preferably, also comprise the display unit that can demonstrate described data in the monitoring alarm 20.
In the present embodiment, monitoring alarm 20 is installed on outside the gas heater main frame 10, but the utility model is not limited to this, equally can be by rational space layout, monitoring alarm 20 is installed on gas heater main frame 10 inside, the installation that is integrated in one, rational deployment gets final product under the situation that does not influence the each several part normal function.
In the present embodiment, as indoor CH
4And/or the recovery of CO content is normal, or after the indoor temperature recovery normally, energy supply control module 30 is communicated with the general supply of gas heater main frame 10 again.
Gas heater main frame 10 is finished gas heater and is communicated with basic functions such as fuel gas, igniting, the CH in 20 pairs of environment of monitoring alarm
4Monitor in real time with the gas content of CO, simultaneously the temperature of environment is monitored in real time, if monitor wherein CH
4The content of content, CO in each exceeds standard, or temperature exceeding standard in the environment, then send the sound and light signal of warning, cut off the power supply of gas heater simultaneously by energy supply control module 30, do not allow gas heater work on by the alarm in the monitoring alarm 20.CH in the present embodiment
4Standard value, the standard value of CO and the isoparametric setting value of standard value of environment temperature can adjust according to actual state.
Fig. 2 is the circuit diagram of the utility model embodiment.As shown in Figure 2, when monitoring alarm 20 monitors in the environment CH or CO exceeds standard, or environment temperature is when exceeding standard, monitoring alarm 20 self output alarm signal also has the dump module in the energy supply control module 30, the dump module is sent the dump signal simultaneously, its output port is J2, J2 connects the J1 of energy supply control module 30, and the J3 of energy supply control module 30 directly connects supply socket 40, and the J5 of the supply socket 40 of gas heater connects the J4 of energy supply control module; The output signal of J2 port is in the home: J2-1pin=12V, J2-2pin=GND, J2-3pin=GND; When having arbitrary numerical value to exceed standard in CH4 content, CO content or the environment temperature in the environment, the corresponding port level will produce variation from low to high, i.e. J2-1pin=12V, and J2-2pin=12V, J2-3pin=GND, in the case, triode Q
2And Q
1Conducting respectively, thus make relay K 1 send the action that disconnects L line power supply, and the L line is connected on the normally-closed contact of relay, cuts off the general supply of gas heater thus.After each parameter in the environment returned to normal range (NR), the output signal of J2 port returned to J2-1pin=12V, J2-2pin=GND, and J2-3pin=GND, relay K 1 just can reset, and gas heater just can electrically connect with power supply again.
CH in the present embodiment environment
4Exceeding standard with CO to derive from the leakage of gas heater itself, also may derive from other equipment in the environment, leak as air inlet pipeline, or the burning of kitchen range etc.
The utility model can be to fuel gas CH in the environment
4Monitor with content and the temperature of CO; in case arbitrary fuel gas content overproof or environment temperature exceed standard (for example breaking out of fire situation); monitoring alarm is made security reaction immediately; and output sound and light alarm signal; out-put supply controls signal to energy supply control module simultaneously; force disconnect gas heater general supply realizes safeguard protection, make the use of water heater and home-use gas process more safely, feel at ease.
The utility model is not limited to the foregoing description, and many variation designs can also be arranged.For example, the cut-out mode in the accompanying drawing 2 can also be that L, N cut off simultaneously; Power-off modular in the energy supply control module can independently be inserted on the socket, also can be installed in the inside of gas heater main frame; CH
4Monitoring, CO monitoring and environment temperature monitoring can be carried out various combination etc. on demand, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the protection domain of this patent claim.
