Abstract

The ion probing ring for flame features use of range's pot frame as ion probing electrode, long service and higher sensitivity. The adjustable probing needle is a fine refractory alloy wire and features high sensitivity and flexible adjusting unit that allows draw the alloy wire after its head is burnt off, so it is unnecessary to exchange probing needle assembly. They may be used for one burner individually or in combination.

Description

Ionisation probing ring for flame and adjustable probing needle

The present invention relates to flame ion spy ring and probe that a kind of burner, especially gas kitchen ranges use.

The blowout protection majority of current combustion gas burner still adopts the thermopair flame detection, because its thermal inertia is excessive, the life-span is shorter, is replaced by the ion detection technology in high-grade water heater.Because gas-cooker generally is that eyes kitchen range and many ring fires and place to use are windy, thus to produce two main fiery, low baking temperature, a series of detection difficult such as unstable fire.The gas-cooker that security problem that Here it is is outstanding equally still can not base oneself upon the reason in market with the ion detection technology.It is to need one of key that solves that the improvement probe structure improves detection sensitivity.What deserves to be explained is that the diameter of probe is related to speed of detection, serviceable life, also be related to detection sensitivity.For obtaining high sensitivity, should use the probe below 1.5 millimeters on kitchen range, this will prevent probe ablation replacing problem in use.

The probe that the purpose of this invention is to provide a kind of new ideas promptly uses kitchen range pot frame double as " probe ", i.e. stent-type flame ion detector, and following abbreviations spy encircles; To the minor diameter probe, be modified into the reserve type structure of scalable installation length, with the high sensitivity and the degree of stability that reach detection and avoid kitchen range useful life period domestic demand repeatedly change, throw away the probe assembly of using.Economical and convenient.

The present invention is achieved in that the pot frame that at first adopts metal and the detection lead electrical coupling of it and testing circuit, and insulate with stove.The leg of annular pot frame elongation is a whole probe.And the pot metal construction of frame and cooking pot spoon also have ion and collect power, and like this, detection sensitivity is strengthened.Secondly the porcelain tube of common probe is transformed, open one and half logical notches at the one end, adorn a heat-resisting elastic collar outside it, probe adds and grows to about ten centimetres, when compressing probe and detection line by collar and porcelain tube notch, because the elasticity of collar opening, make the probe can artificial upper and lower twitch with screw, this just can (about 6 months to 1 year) change the probe extension elongation easily after probe is ablated, satisfy and survey requirement.

Adopt easy like this measure, can produce following effect:

1, invests a pot frame and collect function, become and visit ring, increase the flame detection sensitivity with ion.

2, it is semipermanent visiting the life-span of encircling.

Actual when 3, the spy ring uses separately on monocycle fire kitchen range is one " probe of hiding ", and outward appearance is just the same with no flame detection kitchen range, neat appearance.

4, tuning probe is improving under the prerequisite of detection sensitivity, and the loss that can avoid probe assembly repeatedly to change is easy to adjust.

Be illustrated with an embodiment below.Fig. 1 is structure and an installation diagram of visiting ring and tuning probe: the pot frame that 4-5 leg 1 and ring stand 2 are formed among the figure is spy and encircles.It is placed on the kitchen range face 3 and with the kitchen range face insulate (can be guaranteed by former enamel layer).Visit during use to encircle and keep machinery and electrically contact with the dish 4 that ladles out soup, spring 5 in use encircles to have with spy and electrically contacts by screw 6 connection detection lines 7, metal pan 17, is of value to the collection ion, becomes and visits the some of encircling, but this is (take off pot, sensitivity still guarantees) not necessarily.The distance L 1 of leg 1 and main fire lid 15 craters is littler of well, but answers＞5 millimeters.

Tuning probe is by alloy silk 8, porcelain tube 9, and elastic collar 10 and screw 11 are formed.About 10 centimetres of alloy filament lengths, 1.2 millimeters of diameters and the loose fit of insulation porcelain pore, porcelain tube bottom fluting N also is with elastic collar, and elastic collar is also slotted W so that produce elasticity on the screw hole opposite.Compress detection line 7 and alloy silk 8 with screw 11, wiping power (can spur with hand) is visited in suitably rubbing when regulating its snap-in force with the twitch of acquisition alloy silk.Pressing plate 12 is fixed on porcelain tube on the center fire tube 13, alloy silk and middle internal heat cover 14 crater distance L 2 within the 1.5-3MM scope for well.

Visiting ring and probe can use separately, also can unite use.This will determine according to the structure of concrete kitchen range.
