Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
As shown in Figure 1-2, a kind of electric drying oven with forced convection, including casing 1, the casing 1 are provided with control panel and close
Door is closed, the control panel includes display screen 2, regulation button 3 and shift knob 4, and the sealed door is provided with handle 5, described
Control system is provided with casing 1, the control system includes PLC；
The sealed door is provided with emergent window 6, and the emergent window 6 is tightly connected with sealed door, the lower end of the emergent window 6
It is hinged with sealed door, the upper end of the emergent window 6 is fixedly connected by interlocking mechanism with sealed door；
The interlocking mechanism includes dead bolt 10, magnet 9 and electromagnet 8, is provided with and inserts at the corresponding dead bolt 10 of the emergent window 6
Hole, the dead bolt 10 are located in jack, and the magnet 9 is fixed on one end away from emergent window 6 of dead bolt 10, the electromagnet 8
Positioned at one end of the remote dead bolt 10 of magnet 9, gap is provided between the electromagnet 8 and magnet 9；
The electromagnet 8 is electrically connected by circuit control module with PLC.
Preferably, it is additionally provided with alarm lamp 7 on the casing 1.
Preferably, the making material of the sealed door is safety glass.
Preferably, sealing ring is provided between the emergent window 6 and sealed door.
Preferably, the display screen 2 is LED display.
In fact, when drying box works, sealed door is to be in close state, is added if necessary to midway, then opens and answer
Anxious window 6 is added, because the emergent area of window 6 is small, when opened, it is relative with extraneous heat exchange in drying box can be compared with
It is few, so as to reduce the loss of heat.
If drying box has worked a period of time, and it is less than default safety time in PLC this period, then window 6 of meeting an urgent need
It can be opened, principle is：PLC controls the sense of current of electromagnet 8 by circuit control module, when the logical orientation electricity of electromagnet 8
Stream so that suction is produced between electromagnet 8 and magnet 9, then will hold magnet 9 so that dead bolt 10 departs from emergent window 6, so
Emergent window 6 can just be opened.
If drying box has worked a period of time, and it is more than the default safety time in PLC this period, then window of meeting an urgent need
6 cannot be opened, and principle is：PLC controls the sense of current of electromagnet 8 by circuit control module, when electromagnet 8 it is logical with
Above-mentioned directional current electric current in opposite direction so that repulsion is produced between electromagnet 8 and magnet 9, then will push away magnet 9, make
The emergent window 6 of the insertion of dead bolt 10 is obtained, so emergent window 6 cannot just be opened.
This setup main purpose be in order to prevent drying box work a period of time, i.e., when more than safety time,
It is too high to dry the temperature inside the box, when preventing that emergent window 6 is opened, internal heat wave burn operating personnel.
Compared with prior art, electric drying oven with forced convection of the present utility model is ingenious in design, simple in construction, should by setting
Anxious window 6, when can add article in midway, the loss of heat is reduced, then controlled by the combination of PLC and interlocking mechanism, it is corresponding
The opening time of anxious window 6 carries out strict control, so as to ensure that dry mass, reduces accident odds.
Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real
The content being not limited to new technical scope on specification, it is necessary to which its technology is determined according to right
Property scope.
