Fig. 1 is a kind of example structure schematic diagram for the gas heater that the utility model is proposed；
Fig. 2 is the functional-block diagram of control circuit in the gas heater that the utility model is proposed.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Embodiment one, the present embodiment describe in detail by taking the gas heater with gas water heater control circuit as an example
The structure and principle of gas heater and gas water heater control circuit, as shown in Figure 1 and Figure 2, the gas heater include shell
10 and control circuit, the control circuit includes master control borad 11 and operation display 12, be provided with master control borad 11 master controller and
For connecting the master control power supply terminal of AC power, operation display 12 includes display control module, connected with display control module
The key press detecting circuit connect, in addition to converter 13 is received, receiving converter 13 includes control module, connects respectively with control module
The current detection module and relay connect, master control power supply terminal are connected after connecting the normally opened contact K1 of relay with AC power,
Master controller and display control module are established with control module respectively to be communicated to connect.The control principle of this control circuit is：When connecing
When receipts converter is upper for the first time electric, the normally opened contact K1 of relay is closed, electricity on master controller, now to each load progress self-test
And initialize each parameter.The control module for receiving converter 13 receives the water-flow signal of current detection module detection, display control
Module detects user's Cao Zuoanjian signal by key press detecting circuit and is sent to control module, and the master controller believes current
Number and user's Cao Zuoanjian signal send to master controller, status signal is generated by master controller, and be sent to control module,
Control module is disconnected according to status signal control relay, and power supply and master controller are disconnected, and then be connected with master controller
Load such as transformer power consuming load powers off, and reaches the purpose that electric energy is saved when user is without using gas heater.Wherein, shape
State signal is after master controller judges that the signals such as no loaded work piece, manual operation meet certain time, into standby shape
State.
When operation display has operation, display control module will be instructed by power line transmission in reception converter
Control module, or display control module receive when having water-flow signal of current detection module detection, now receive in converter
Control module control relay closure, power supply and master controller are connected, and master is issued in the instruction after control module is converted
Controller, control water heater burning, to reach required state, the detecting element of current detection module can use current to pass
Sensor realizes that current detection module handles the pulse signal that water flow sensor detects, and produces water-flow signal and send to aobvious
Show control module.
Because gas heater is generally located on kitchen, and therefore bath water point, operates display typically between bathing
12 are generally located between bathing, easy to operation, and master control borad 11 and reception converter 13 are generally located on the outer of gas heater
On shell 10, communicated in order to facilitate master controller with control module, display control module is also associated with the first power line carrier module, control
Molding block is connected with the second power line carrier module, passes through electricity between the first power line carrier module and second power line carrier module
The line of force communicates.
User with water spot it is more when, operation display 12 have it is multiple, it is multiple operation display 12 structure composition it is identical,
Its display control module is connected with receiving the control module of converter respectively, and operation display 12 can be line control machine.
Receiving converter 13 has power supply terminal, and the input of power supply terminal is connected by plug 14 with power outlet 15,
The output end of power supply terminal is connected after wherein connecting the normally opened contact K1 of relay all the way with master control power supply terminal, for master control
Plate exports alternating current, connects change-over circuit all the way in addition, is powered after alternating current is changed into control module.That is,
Under conventional sense, the power supply terminal of receiving converter 13 is often connected with external power source, and it is touched by the normally opened of control relay
Point K1 controls whether to power for master control borad.Because the load of receiving converter 13 is less, overall power is relatively low, in order to further subtract
Low power consumption, receiving converter 13 can also set low power consumption switch circuit, only adopt system wake-up when some conditions meet
With low consumption circuit conventional in the prior art, will not be described here.
For the ease of assembling, master control borad 11 and reception converter 13 are typically arranged on the shell 10 of gas heater,
Because both positions are nearer, connected by wire, communication mode preferably uses serial communication, and therefore, master controller passes through
Serial ports is connected with control module.
Certainly, it is to be also not limited to the example above to limitation of the present utility model, the utility model that described above, which is not,
The variations, modifications, additions or substitutions that those skilled in the art are made in essential scope of the present utility model,
Also the scope of protection of the utility model should be belonged to.
