Description
Technical field
The utility model relates to electric-heating technology field, the protection control device of specifically a kind of electric furnace.
Background technique
Currently, electric heating utensil is the more commonly used kitchen appliance of family, such as electromagnetic oven, light-wave cooker, micro-wave oven, electric ceramic heaters
Deng heating utensil, heating is fast, and power is big, the flames of anger, deep to be liked by family.
The structure of traditional power adder tool generally comprises heater, control heating element, and control heating element passes through conducting wire
It is connect with heater, power supply.Wherein, which includes control core plate and control switch, is closed using control switch
Whether conjunction and disconnection can make to control core plate control fever body running.
However, traditional control switch is generally connected with the triode of a protective effect, and when triode damage, control
Switch still can be closed, and generate heat body running, and control action cannot be played and heater is made to stop working by controlling core plate, can only
Electric heating could be stopped working by disconnecting general supply, be easily damaged the other electric elements of electric ceramic heaters, there are security risks.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of protection control dress of electric furnace
It sets, structure is simple, and protecting effect is good, improves operation stability and reliability, reduces security risk, guarantees the use matter of product
Amount.
The goal of the invention of the utility model is achieved in that a kind of protection control device of electric furnace, including fever
Body, control heating element, the control heating element include control switch part and the control for controlling heater energization or power-off
Core plate block, control switch part are equipped at least two triodes, and at least two triodes are connected in series in control switch part and control
Between the connection of coremaking plate.
It is optimized according to above-mentioned, the control switch part is set there are two triode, and two triodes are respectively the one or three
Pole pipe and the second triode, the pole b of the first triode, the pole b of the second triode are connected separately with control core plate block, the one or three pole
The pole c of pipe is connect with control switch part, and the pole e of the first triode is connect with the pole c of the second triode.
It is optimized according to above-mentioned, the pole e of second triode is connected with ground wire.
It is optimized according to above-mentioned, the heater and control switch part are connected in series on power supply by conductor wire.
It is optimized according to above-mentioned, the control switch part is normally opened control relay.
Utility model has the advantages that passing through the structure of at least two triode and control switch part, control core plate
Cooperation, only whole triodes simultaneously turn on, and control switch part is just attracted, and heater can just work, and increase protection intensity,
Operation stability and reliability are improved, security risk is reduced, guarantees the use quality of product.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the utility model preferred embodiment.
Specific embodiment
The utility model will be further described with reference to the accompanying drawing.
With reference to the accompanying drawings shown in 1, the protection control device of the electric furnace of the utility model comprising heater 1, control add
Thermal part, the control heating element include the control switch part 2 and control core plate block 3 for controlling the energization of heater 1 or power-off,
Control switch part 2 is equipped at least two triodes, and at least two triode is connected in series in control switch part 2 and control core plate
Between the connection of block 3.
In prioritization scheme, the control switch part 2 is set there are two triode.The heater 1 and control switch part 2 are logical
Conductor wire is crossed to be connected in series on power supply.Two triodes are respectively the first triode 4 and the second triode 5, the first triode 4
The pole b, the second triode 5 the pole b be connected separately with control core plate block 3, the pole c of the first triode 4 and control switch part 2 connect
It connects, the pole e of the first triode 4 is connect with the pole c of the second triode 5.Moreover, the pole e of second triode 5 is connected with ground
Line.
That is, two triodes simultaneously turn on, and control switch part 2 can just be inhaled when the port input high level of control core plate block 3
Work is closed, heater 1 has power output that can also work.However, when the first triode 4 damages, the pole c of the first triode 4 and e
Pole conducting, and the second triode 5 is to disconnect.Although at this point, control core plate block 3 do not control heater 1, the control
Switch member 2 processed is normally opened control relay.Control switch part 2 is to disconnect, and cannot be worked, so that heater 1 can not work
Make.Increase protection intensity, improve operation stability and reliability, reduces security risk, guarantee the use quality of product.
Above-mentioned specific embodiment is only the preferable specific embodiment of the utility model effect, all electricity with the utility model
The identical or equivalent structure of the protection control device of heating furnace, it is within the protection scope of the present utility model.
