The break-make of valve and first row air valve controls the heating process of steam box.
Preferably, the first row air valve is normally closed type air bleeding valve.
Preferably, the first row air valve is air bleeding valve open in usual.
A kind of multi-stage combination guard method based on above-mentioned steamer, it is characterised in that this method includes：When steamer powers on, institute
State the closing of central controller controls second row air valve；After user is by key-press module input instruction, the central controller executes
The instruction and control intake valve and first row air valve opens or closes, to control the heating process of steam box；When travel switch disconnects,
Indicate that chamber door is opened, the central controller controls first row air valve is opened；When travel switch is closed, indicate that chamber door is closed, institute
Central controller is stated by controlling the break-make of intake valve and first row air valve to control the heating process of steam box.
Preferably, the first row air valve is normally closed type air bleeding valve.
Preferably, the first row air valve is air bleeding valve open in usual.
In multi-stage combination protection steamer disclosed by the invention, pass through key-press module, mechanical valve, first row air valve, second row
The collective effect of air valve, intake valve, travel switch and handle type door lock forms a kind of active with passive, normal with abnormal, machine
The multi-stage combination means of defence that tool and electronics are combined with each other, achieves that safety is more preferable, pressure adjusts more flexible effect, effectively
The safe to use of steamer is ensured.
Description of the drawings
Fig. 1 is the structural schematic diagram that multi-stage combination of the present invention protects steamer.
Fig. 2 is the circuit block diagram that multi-stage combination of the present invention protects steamer.
Specific implementation mode
The present invention is described in more detail with reference to the accompanying drawings and examples.
The invention discloses a kind of multi-stage combination protect steamer, in conjunction with shown in Fig. 1 and Fig. 2 comprising have multiple steam boxs 1,
The chamber door of one central controller 5 and a key-press module 6, the steam box 1 is equipped with handle type door lock 2, and the steam box 1 is equipped with row
Cheng Kaiguan 3, the travel switch 3 is adjacent with handle type door lock 2, and drives travel switch 3 to close when handle type door lock 2 is locked
It closes, drives travel switch 3 to disconnect when handle type door lock 2 is opened, first row air valve 4, second exhaust are additionally provided on the steam box 1
Valve 7 and mechanical valve, the mechanical valve are used to automatically open when the pressure in steam box 1 is more than its threshold value, the second row air valve 7
It is air bleeding valve open in usual, the key-press module 6, travel switch 3, first row air valve 4 and second row air valve 7 are electrically connected in
Controller 5 is entreated, wherein：
When steamer powers on, the central controller 5 controls second row air valve 7 and closes；
