Abstract
A kind of gas combustion range flameout protector installs thermocouple seat on kitchen range body, and by the installation of TC in thermocouple seat, thermocouple seat connects controller, continuous sampling end flue temperature；When gas-cooker kindling state; temperature can be passed to the thermocouple being mounted in thermocouple seat by thermocouple seat by the flame of kitchen range; controller acquires the signal of thermocouple at regular intervals and calculates temperature value; if in safety time; the temperature data of acquisition continuously declines; controller is judged as flame-out, and output control signal closes gas cut off valve, plays safety protection function.
Description
Technical field
The present invention relates to kitchen range fields, more particularly, to a kind of blowout protection of commercial gas-fired stove.
Background technique
Commercial gas-fired stove generally has a small fire device, plays ignition action；When small fire is extinguished, protective device starting is closed
Gas valve is closed, safeguard protection is played the role of；This protective device is generally placed in small fire using probe, by probe, utilizes fire
The electrical property of flame, detection flame whether there is；Since small fire is unstable, maloperation is more；Also have using electroheat pair warming method, lead to
It crosses setting certain temperature and carrys out starting protection device, still, since thermocouple has certain thermal inertia, tend not in safety time
Interior starting protection device, there are security risks；Meanwhile thermocouple works in burner hearth, it is easy to damage.
Summary of the invention
To solve the deficiencies in the prior art, the object of the present invention is to provide a kind of gas extinguishing fire protective devices, in kitchen range body
Upper installation thermocouple seat by controller continuous sampling electric thermo-couple temperature, judges that kitchen range are by the installation of TC in thermocouple seat
It is no flame-out, thus starting protection device.
To realize the above-mentioned technical purpose, the technical solution adopted in the present invention is as follows：
A kind of gas combustion range flameout protector comprising the thermocouple seat that is mounted in gas stove fire head is mounted on thermoelectricity
The controller of thermocouple, connection thermocouple in even seat.
The thermocouple seat main body is that tubulose and upper end closed, body top periphery are disposed with cooling fin, in body top
It is disposed with the internal screw thread matched with thermoelectricity even thread, tube body lower disposed has external screw thread；
Preferably, thermocouple seat material is heat resisting steel；
Preferably, thermocouple seat passes through lower thread bottom middle position of the spinning in burner, lower port from top to bottom
Outside；
Preferably, the cooling fin of thermocouple seat is plates, and top is bullet.
The thermocouple top is disposed with the external screw thread matched with thermocouple seat internal screw thread, and thermocouple is by being threaded into
In thermocouple seat.
The controller plug-in samples thermo-electric couple temperature data continuous several times, in safeguard time, if
The temperature of sampling continuously declines, and is judged as flame-out, and controller controls stop valve and closes combustion gas.
Detailed description of the invention
In order to illustrate the embodiments of the present invention more clearly, attached drawing needed in the embodiment will be done simply below
It introduces, it should be apparent that, drawings in the following description are only some embodiments of the invention, for ordinary skill people
For member, without creative efforts, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is scheme of installation of the present invention.
Fig. 2 is component connection schematic diagram of the present invention.
Fig. 3 is thermocouple seat of the present invention and thermocouple schematic diagram.
It is denoted as in figure：
1, thermocouple seat；2, thermocouple；3, controller.
Specific embodiment
With reference to the attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention carries out clear, complete
Ground description, it is clear that described embodiments are only a part of the embodiments of the present invention, rather than whole embodiments.Based on this hair
Embodiment in bright, those of ordinary skill in the art without making creative work, every other reality obtained
Example is applied, the scope of the present invention is belonged to.
As shown in Fig. 2, burner bottom intermediate arrangement has threaded hole, by thermocouple seat 1 out of burner, by screwing into
In burner bottom thread hole, 1 lower end aperture of thermocouple seat be located at burner bottom lower part, by thermocouple 2 screw in thermocouple seat 1 in,
2 output signal line of thermocouple is connect into controller 3.
When gas-cooker catches fire state, the flame of kitchen range can by thermocouple seat 1, temperature passed to be mounted on thermocouple seat
Thermocouple 2 in 1, controller 3 acquires the signal of thermocouple 2 at regular intervals and calculates temperature value, if in safety
In time, the temperature data of acquisition continuously declines, and controller 3 is judged as flame-out, and output control signal closes gas cut off valve,
Play safety protection function；This example is primary every acquisition in 0.5 second, acquires data 10 times, 5 seconds, when：T1>T2>T3>T4 >T5>T6
>T7>T8>T9>When T10, valve is closed.
When the more previous temperature collection rising of a certain temperature collection, then restarts to acquire from the climb data, compare, sentence
It is disconnected.
When flame-out, since combustion gas, air stop entering burner not yet, these gases pass through the heat dissipation of thermocouple seat 1
Piece, so that thermocouple seat 1 and 2 fast cooling of thermocouple being mounted in thermocouple seat 1, in this way, thermocouple 2 can be quickly
End flue temperature is perceived, the thermal inertia of thermocouple is reduced.
Remarkable advantage of the invention is：Thermocouple seat 1 is mounted in burner, with direct flame contact, can preferably be passed
Burner flame temperature is led, using heat-resisting steel material, long service life；Thermocouple 2 is mounted in thermocouple seat 1, is avoided in burner hearth
It is interior directly to scorch, service life is greatly improved, is also convenient for changing, repairs；The sampling of controller 3 is compared, judgment method, can
Judge whether to stop working within the security settings time and take measures, overcomes the thermal inertia of thermocouple.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention；
Various modifications to these embodiments will be readily apparent to those skilled in the art, defined in the present invention
General Principle can be realized in other embodiments in the case where not departing from spirit or scope of the invention.Therefore, originally
Invention will not be defined to the embodiments shown herein, and be to fit to and the principles and novel features disclosed herein
Consistent widest scope.
