Abstract
The utility model relates to a timing controller capable of cutting off a fuel gas channel automatically comprises a controller core, solenoid valves and thermocouples, wherein the controller core is connected with at least one control switch; each solenoid valve and the corresponding thermocouple are connected in series through connecting wires; and the output end of each control switch is connected in parallel to the connecting wires between the solenoid valve and the thermocouple through another connecting wires and comprises two terminals, and one of the two terminals is grounded. A microcomputer is adopted as the controller core, can be connected with a plurality of relays, and controls two or more fuel gas channels simultaneously through independent control of each relay; and two or more fuel gas channels are controlled simultaneously through single controller, so that the operation process is simplified, and the production and use costs are reduced simultaneously.
Description
Technical field
The utility model relates to electrical equipment field, especially a kind of time controller that can automatically cut off fuel gas path.
Background technology
Traditional gas-time controller is timing jingle bell device simple, that use integrated circuit or mechanical device, finishes by auditory tone cues user timing; This kind of device can not cut off fuel gas path automatically, deposits risk in the use; And every traditional gas-time controller can only be controlled 1 road fuel gas path simultaneously, can only rely on and equip many controllers simultaneously for the control of multichannel fuel gas path, does not possess the convenience of operation, and cost is also higher.
Utility model content
The technical problems to be solved in the utility model is: a kind of time controller that can automatically cut off fuel gas path is provided, can be applicable to all use combustion gas kitchen range and household electrical appliance with magnetic valve and protection thermocouple.
The utility model solves the technical scheme that its technical problem adopts: a kind of time controller that can automatically cut off fuel gas path, comprises controller core, magnetic valve and thermocouple; Described controller core connects at least one way control switch; Between described magnetic valve and thermocouple, be connected in series by connecting line; The output of described gauge tap by other connecting line and be connected in magnetic valve and thermocouple between connecting line on; The output of described gauge tap comprises two-way terminals, wherein one end ground connection of described two-way terminals.
Further, gauge tap described in the utility model is relay; Described controller core is micro computer.
In order to simplify the operation course and to reduce costs, controller core described in the utility model is controlled separately each gauge tap, and multiple gauge taps are worked simultaneously or worked respectively.
The beneficial effects of the utility model are, solve the defect existing in background technology, the utility model adopts micro computer as controller core, can connect many relays, reaches by every relay being carried out to control separately the object of simultaneously controlling the above fuel gas path control in 2 tunnels and 2 roads; Realize single controller and control 2 tunnels and fuel gas paths more than 2 tunnels simultaneously, simplify the operation course and reduce and produce and use cost simultaneously.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
In figure: 1, controller core; 2, relay; 3, magnetic valve; 4, thermocouple; 5, fuel gas path; 6, coil; 7, armature; 8, connecting line.
Detailed description of the invention
With preferred embodiment, the utility model is described in further detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of time controller that can automatically cut off fuel gas path as shown in Figure 1, comprises controller core 1, magnetic valve 3 and thermocouple 4; Described controller core connects at least one way control switch; Between described magnetic valve and thermocouple, be connected in series by connecting line; The output of described gauge tap by other connecting line and be connected in magnetic valve and thermocouple between connecting line on; The output of described gauge tap comprises two-way terminals; For ensureing safety, wherein one end ground connection of described two-way terminals.
Magnetic valve 3 is by after manual unlocking, fuel gas path conducting 5, the heat that fuel gas buring produces makes the thermocouple 4 that approaches flame produce electromotive force, this electromotive force acts on the coil 6 of magnetic valve inside through two connecting lines 8 that are connected to magnetic valve 3 terminals, produce magnetic, attract the armature 7 in magnetic valve and make magnetic valve remain on open position, ensureing that fuel gas path continues conducting.When relay 2 input circuits receive after the signal that controller sends, output loop conducting, magnetic valve two input electromotive force are zero, and coil no longer produces magnetic, and armature is promoted to reset by the spring of magnetic valve inside, cuts off fuel gas path, and then makes fray-out of flame.
And adopt micro computer as controller core, and can connect many relays, reach by every relay being carried out to control separately the object of simultaneously controlling the above fuel gas path control in 2 tunnels and 2 roads.Realize single controller and control 2 tunnels and fuel gas paths more than 2 tunnels simultaneously, simplify the operation course and reduce and produce and use cost simultaneously.
What in above description, describe is detailed description of the invention of the present utility model, various not illustrating is construed as limiting flesh and blood of the present utility model, person of an ordinary skill in the technical field read after description can to before described detailed description of the invention make an amendment or be out of shape, and do not deviate from essence and the scope of utility model.
