Summary of the invention
The purpose of this invention is to provide a kind of to the cooker internal temperature thermometric self-adapted temperature sensor of gas-cooker accurately.
The present invention realizes with following mode.The self-adapted temperature sensor of gas-cooker comprises the sensing cap, thermopair, sliding sleeve, orienting sleeve, guide rod, spring, guide frame, the thermopair head is contained in the sensing cap, lower end of the guide rod is fixed with pivot pin, pivot pin is installed in the chute of guide frame, microswitch is contained on the guide frame, sliding sleeve upper end outer ring surface is connected with locating ring one and anti-fire ring, sliding sleeve upper end inner ring surface is connected with locating ring two, guide rod is a pipe always, its upper end outer ring surface and locating ring two are affixed, and orienting sleeve lower end and location-plate are affixed, and spring one upper end leans and connects the sensing cap, the lower end leans and connects locating ring one, spring two is contained in the orienting sleeve and entangles guide rod, and its upper end leans locating ring two, and the lower end leans the orienting sleeve bottom, sliding sleeve is sleeved on the orienting sleeve, and the lead of thermopair passes guide rod, guide frame is extended outside the guide frame.
The also available following mode of the present invention is finished:
The external diameter of sensing cap of the present invention is less than the internal diameter of anti-fire ring.
Locating ring one of the present invention is contained in the anti-fire ring.
The elastic force of spring one of the present invention is greater than the elastic force of spring two.
Location-plate of the present invention and guide frame anchorage clip are contained on the panel of gas-cooker.
The self-adapted temperature sensor compact conformation of gas-cooker, easy for installation, sensing cap hunting range is bigger, closely contacts with the cooker bottom, the putting position of energy various cooker of self-adaptation and cooker, be quick on the draw, discern pan-free state automatically, the fire-proof and thermal-insulation ability is strong, the temperature measurement accuracy height, temperature transfer is accurate, can accurately survey cooker bottom temp signal in real time, gathers and offers controller and control fired state automatically.The self-adapted temperature sensor of gas-cooker is specially adapted at embedded intelligence control gas-cooker and does not have and make temperature sensor usefulness on the soot controlling gas-cooker.
Description of drawings
The structural representation of the self-adapted temperature sensor of Fig. 1 gas-cooker.
Embodiment
As shown in Figure 1, the self-adapted temperature sensor of gas-cooker of the present invention comprises sensing cap 1, thermopair 2, sliding sleeve 3, orienting sleeve 4, guide rod 5, location-plate 6, spring 1, spring 29 and guide frame 7, sliding sleeve 3 upper end outer ring surfaces are connected with locating ring 1 and anti-fire ring 10, locating ring 1 is contained in the anti-fire ring 10, sliding sleeve 3 upper end inner ring surfaces are connected with locating ring 2 12, guide rod 5 is pipes always, its upper end outer ring surface and locating ring 2 12 are affixed, guide rod 5 lower ends are fixed with pivot pin 14, orienting sleeve 4 lower ends and location-plate 6 are affixed, spring 29 is contained in the orienting sleeve 4 and entangles guide rod 5, its upper end leans locating ring 2 12, the lower end leans orienting sleeve 4 bottoms, sliding sleeve 3 is sleeved on the orienting sleeve 4, and spring one 8 upper ends lean and connect sensing cap 1, and the lower end leans and connects locating ring 1, thermopair 2 heads are contained in the sensing cap, and the lead of thermopair 2 passes guide rod 5, guide frame 7 is extended guide frame 7 outsides by plug 17 and controller plug-in mounting.Location-plate 6 is contained on the panel 15 of gas-cooker with guide frame 7 anchorage clips, and pivot pin 14 is installed in the chute 13 of guide frame 7, and microswitch 16 is contained on the guide frame 7.
The sensing cap 1 of the self-adapted temperature sensor of gas-cooker of the present invention adopts spring 1 to be connected with sliding sleeve 3, sensing cap hunting range is strengthened, when putting cooker, cooker bottom and sensing cap 1 contact in the arbitrfary point, sensing cap 1 is because the elastic reaction of spring 1 can self-adaptation be adjusted angle, thereby closely contact with the cooker bottom automatically, increase contact area, effectively improve the precision that detects the cooker bottom temp.The affixed anti-fire ring 10 in sliding sleeve 3 upper ends plays the fire-proof and thermal-insulation effect; can prevent effectively that combustion flame from directly burning on the sensing cap; and can prevent that burning from producing radiation of high temperature; make sensing cap 1 can accurately measure the cooker temperature inside; rather than the temperature of flame, and can protect the circuit of thermopair 2.Guide rod 5 is designed to straight circular tube structure, makes thermopair 2 wirings more reasonable, and by sliding sleeve 3, orienting sleeve 4 and 5 three layers of thermal insulation protection thermocouple wire of guide rod.
