Description
Technical field
The utility model relates to a kind of gas-cooker, particularly a kind of gas-cooker knob with luminous indication.
Background technology
In cooking process, when the user is busy with carrying out other operation, may have no time to bend over to observe the firepower size, because flame itself is blocked by cooking wares such as pots, and then cause and attend to one thing and lose sight of another, influence culinary art progress or culinary art effect.Most convenient is observed firepower is indicating positions at the combustion gas knob, but, it is but relatively more difficult that clear and eye-catching indicating device is set on knob, its reason is: the one, and opening of plug valve is the process of a compound motion, need first push-turn key to strike sparks before gas-cooker work, and then the Unscrew air valve just can be finished, the knob center just in time is the rotating shaft of plug valve, structure is too compact, and general indicator elment is difficult to settle on it, and the then clear inadequately identification of common sign is set; The 2nd, during knob work, its rotational angle range is between 0～165 °, if light-emitting device instructions is set on knob, it connects lead and also will move in slewing area, after long-time the use, lead may occur connecting and rupture because of tired, perhaps getting loose appears in jointing, and can't show.
The utility model content
The purpose of this utility model be to provide a kind of simple and reasonable, cost of manufacture is low, flexible operation, know the gas-cooker knob with luminous indication that shows firepower size, security performance height, long service life by bright degree, to overcome weak point of the prior art.
A kind of gas-cooker knob by this purpose design with luminous indication, comprise the knob that is arranged in the fuel gas plug valve rotating shaft, its architectural feature is that top knob portion is provided with light-emitting component, and the pin of light-emitting component is electrically connected with the circuit board that is arranged between knob and the plug valve by contact chip.
Described circuit board middle part sky is enclosed within the rotating shaft and is crimped on the spring top, and spring housing is located in the rotating shaft, and the spring bottom joins with the mounting bracket that is arranged on the plug valve, and pin joins with mounting bracket after passing circuit board, and circuit board can slippage up and down on pin.Contact chip is the L font, and its top is provided with the split ring of socket luminous tube pin, its bottom be provided with circuit board on the arc presser feet that joins of positive polar region or negative pole district.This structure can guarantee that circuit board only can carry out axially-movable and can not radially rotate, and contact chip and circuit board keep good contact condition always.
Described circuit board is provided with the positive polar region of expression firepower size, be disposed radially two and above anodal sub-district in the positive polar region, be provided with non-conductive no current zone between the adjacent positive sub-district, anodal sub-district connects with the positive source that is connected with different big or small electric currents respectively, next door, positive polar region is provided with the negative pole district, the negative pole district is electrically connected with power cathode, is provided with the no current district between positive polar region and the negative pole district.
The negative pole pin of light-emitting component will be all the time be electrically connected with negative pole district on the circuit board by contact chip in the utility model, its anodal pin then only plug valve be in open after, just can form conduction with different anodal sub-districts on the circuit board connects, and be electrically connected with the anodal sub-district that has different current strength along with the difference of flame size, the luminosity of light-emitting component also changes synchronously.
When knob is rotated counterclockwise horizontal level, perhaps become 80 °～110 ° scopes with the kitchen range fore-and-aft direction, the brightness of luminous tube is the highest; When knob arrived its outstanding position to the operator dead ahead, the anodal pin of light-emitting component entered the no current district, does not have electric current to pass through, and then knob is not luminous; When knob when the different angles, the anodal sub-district power supply of diverse location is connected on anodal pin and the circuit board, light-emitting component sends the light of varying strength.Can correctly indicate flame size in order to guarantee knob; the central angle in positive polar region or negative pole district is set at 0～165 °; because the effect of luminous packed layer and diffusion material thereof; the light-emitting component uniformly light-emitting of knob; visual range reaches more than 2 meters; knob still can be luminous during not on kitchen range next doors and because of accident extinguishing the operator thus; remind the operator to close total source of the gas (need not remind when these kitchen range have extinguish protection function certainly, but when extinguish protection function loses efficacy, be a safety instruction effect undoubtedly again).
Power supply in the utility model is to continue to use 2 joint 1# dry cells in the battery case on the gas-cooker; need not set up power supply separately; because to make the gas-cooker of blowout protection of thermocouple; 2 joint 1# dry cells are to be in off working state after the pulse igniter igniting in the battery case; luminous knob is in running order always when gas kitchen ranges is worked, and does not have the problem of electric weight deficiency because of with the pulse igniter common source time.
Light-emitting component in the utility model is neon bulb and light emitting diode, light-emitting component is arranged on will have the effect that increases light-emitting area in luminous packed layer and the astigmatic powder.Or preferred high brightness low-power consumption paster luminous tube, little, the luminous index height of its volume, the luminous packed layer that adopts astigmatic powder and plastic package process to make can make light-emitting area 254mm
2Bigger 12.5 times than conventional diode, can observably see at a distance that at distance gas-cooker 2m red led is bright, in the environment that steam fills the air, also can clearly show, this light-emitting component has only 3～4mA by electric current, 2 joint 1# dry cells can use the time more than 4 months, are specially adapted to the needs of the long-time Baoshang in south.
The utility model security performance height, when flame because of accident extinguishing, simultaneously flame-out protection device also lost efficacy and plug valve when being in open mode, knob still is in illuminating state, can remind the operator in time to close source of the gas.Cause fire incident in order to avoid reveal because of combustion gas.
