During value, temperature sensor produces electric current, and the electric-controlled switch of trigger control device 6 is opened, thus connected the triggering circuit of water pump 5,
Thus start water pump 5 and operate.And when in annular tank 3, the temperature of water is less than preset value, it is impossible to trigger temperature sensor
Produce electric current, thus cause the electric-controlled switch controlling device 6 to be closed, and then water pump 5 is closed.
In a preferred exemplary of the present invention, temperature sensor can be thermocouple, and concrete, this is not done by the present invention
Limit.
Additionally, in the present embodiment, preset value can be configured according to user's request, such as, in a preferred exemplary,
Preset value can be 80 degrees Celsius.
As can be seen here, the technical scheme of the present embodiment, it is possible to according to the temperature automatic control water of water in annular tank 3
The opening and closing of pump 5, thus automatically trigger water circulation, it is not necessary to manual operation, use convenient.
Understand based on foregoing description, control the current trigger that device 6 is sent by temperature sensor, in order to prevent controlling dress
Putting fault and cause potential safety hazard, in the present embodiment, be additionally provided with alarm device, this alarm device is connected with temperature sensor,
In temperature sensor detects annular tank 3, the temperature of water reaches certain value, such as, 90 degrees Celsius, triggers dress of reporting to the police
Put, to send alarm signal to user, prevent annular tank 3 in water boiled cause wherein pressure raise and cause safety the most hidden
Suffer from, as required, it is also possible to corresponding relief valve is set.
Embodiment four
Based on foregoing description, in order to make person skilled more clearly and detailedly understand technical scheme, this
Embodiment also proposed the control method of a kind of gas-cooker.Seeing Fig. 4, Fig. 4 is the gas-cooker control method that the present invention provides
Method flow diagram, described method includes:
Step S101, detection is circumferentially positioned at the temperature of the peripheral annular tank of burner.
Wherein, description based on above-described embodiment understands, and the water in annular tank 3 absorbs flue gas and the heat of radiation
Amount, temperature gradually rises, in order to continue to absorb efficiently heat, this programme can detect in annular tank 3 in real time
The temperature of water, in order in time the water of annular tank 3 is replaced by the water that temperature is relatively low,
Concrete, according to foregoing description, this programme can be by the temperature of temperature sensor detection annular tank 3
Degree.Wherein, in a preferred exemplary of the present invention, temperature sensor can be thermocouple.
