Description
[technical field]
The present invention relates to kitchen range test equipment technical fields, and in particular to a kind of kitchen range on-line performance testboard.
[background technique]
Kitchen range are divided by using gas kind: natural gas range, artificial coal gas stove, liquefied petroleum gas stove electromagnetic stove.It is divided by material:
There are cast iron stove, stainless steel stove, enamel stove.It is divided by stove eye: single-hole range, eyes stove, multi-hole kitchen range.It is divided by sparking mode: electric arteries and veins
Cut open firing range, piezoelectric ceramics firing range.It is divided into according to the installation method: desk-top stove, embedded stove.The air inlet mode of embedded kitchen range,
There are following three kinds, is lower air inlet, upper air inlet and side air inlet respectively, in which: (1) lower wind inlet type is by below kitchen range as its name suggests
Into fresh air with oxygen needed for providing full combustion, benefit is that duration and degree of heating is big, and thermic load is high, meets Chinese family vigorous fire quick-fried
Culinary art habit.It is certain it is noted that adding secondary air channel in lower section cabinet, otherwise that embedded lower air inlet kitchen range are but installed
Lack of air will cause fuel gas buring insufficient, generate high-concentration carbon monoxide, and it is tight to even result in igniting explosion, panel cracking etc.
Weight consequence.(2) for the kitchen range of upper air inlet without the aperture on cabinet, it is to enter air from burner using higher burner
's.But effect is not very good this kitchen range in actual use, and mainly the thermal efficiency is low, cannot provide very high temperature.
(3) side air inlet type: this kitchen range set up an air-intaker in panel relative low temperature area, when burning makes the intracorporal air of shell reduce shape
When at negative pressure, cold air can be inhaled into shell along the entrance of air-intaker, when not only providing primary air and the burning of abundance
Required auxiliary air solves the problems, such as yellow flame, and carbonomonoxide concentration is greatly reduced, and the combustion gas leaked can also be from
This air inlet discharges, even if ignition deflagrating of hot occurs in gas leakage, air-flow can also emit as soon as possible from air-intaker, fast
Prompt drop low internal pressure avoids glass panel explosion.Meanwhile cold air enters furnace body by air-intaker, also greatly reduces platform
The temperature of surface glass.This kind of kitchen range thermic load is up to 3.8 kilowatts.
Kitchen range are people's one of tools indispensable in life.But the gas source used due to kitchen range be natural gas,
Artificial coal gas or liquefied petroleum gas etc. directly result in the generation of safety accident if kitchen range leak air when in use, danger
And the life security of operator.Therefore kitchen range detected before factory, traditional detection method be using manually into
The problems such as row checks detection, and it is slow that there are speed, at high cost, and working efficiency is low.

1# stove rated heat input, rated heat load: user inputs 1# stove rated heat input, rated heat load, and other kitchen range parameter settings are same as above；
Step 10: according to step 4, record report screen is clicked to enter；
Wherein: each function button function is as follows in report screen:
1) inquiry is whole: clicking the button, can show all accounting loggings；
2) condition query: clicking the button then can be according to conditional search related statements；
3) report saves: entering preservation into excel form to the accounting logging currently shown；
4) it all deletes: clicking the button, all accounting loggings can be emptied；
Step 11: its automatic detecting step is as follows:
2) pipeline is connected according to step 2, and determines whether gas source has been opened；
2) according to step 7, corresponding gas source valve is chosen in the key frame two of test pictures；
3) according to step 6, in the key frame one of test pictures, set alarm and do not record report " display in option
When then try kitchen range number, product type, sequence number, calculate the time setting number of seconds and test countdown number of seconds；
4) product bar code is swept.
5) it presses " starting " button or steps on " foot-operated ".
6) gas valve automatically opens, at this moment system prompt " sparking ".
7) it strikes sparks and turn-knob is rotated to most high fire position.
8) system detection gas flow is tested after gas flow is stablized automatically into thermic load.
9) after the kitchen range is tested, into key frame one, if unqualified, corresponding kitchen range can be shown red in picture
Color, thermic load precision also show red, and can prompt " NG is retested by start button ".At this moment step, which is equivalent to, returns to
Above, 5) step；If after resurveying or unqualified, but want that skip current kitchen range tests into next kitchen range, then
There are two types of methods, and 1. can modify current kitchen range in picture；2. stepping on " foot-operated " 2 seconds；
If qualified, corresponding kitchen range can show that green, thermic load precision also show green in picture.At this moment system can mention
Show " current kitchen range test is completed, and is please tested by start button into next kitchen range ".At this moment user need to only revolve current kitchen range
Torsion is closed, and is pressed " starting " button or is stepped on " foot-operated ", and system will be tested automatically into next kitchen range, and at this moment step is equivalent to
Return to the 5) step above.
Further, the pneumatic operated valve one, pneumatic operated valve two, pneumatic operated valve three are the SMC pneumatic operated valve that model is VN201A-15A.
Further, the solenoid valve one is the solenoid valve that model is 4V210-08.
