Description

A kind of intelligent decision kitchen boilers from drying burning method

Technical field

The present invention relates to kitchen safety protection fields, and in particular to a kind of intelligent decision kitchen boilers from drying burning method.

Background technique

Currently, the method for cookware anti-dry mainly reequips kitchen range, for example, increasing in the middle position of kitchen range Adjunction touch or contactless sensor, increasing the thermometric mould group that the kitchen range of touch sensor use is PT100 isothermal Spend sensor.But touch sensor requires the center for being mounted on kitchen range, examines to the temperature of cookware bottom It surveys, in order to guarantee that it is contacted with cookware bottom, touch sensor also needs prominent a part.Another part then will contact Formula sensor changes infrared sensor into and is mounted on kitchen range bottom, solves the problems, such as contact.But infrared sensor is still peace Mounted in the lower section of kitchen range centre, it is that infrared lens face stove is low, stove low temperature is detected, then according to temperature value size With dry combustion method threshold value comparison, valve is then closed more than dry combustion method threshold value.The prior art haves the shortcomings that following comparison is prominent:

1. being detected by contact type temperature sensor to stove low temperature, must be requested that cookware bottom and temperature sensor It comes into full contact with, it is necessary to assure the bottom of a pan is smooth, and cookware size, form of pot bottom multiplicity on the market, especially some Baoshang class sand Pot, cookware bottom surrounding protrusion, bottom centre is slightly lower than surrounding, results in cookware bottom that can not touch detection dry combustion method in this way Temperature sensor leads to dry combustion method disabler.

2. cookware in use bottom can with the increase for using the time, when bottom can be bought than newly more than it is some miscellaneous Matter becomes out-of-flatness, before thermal conductivity is also not so good as, so that cookware bottom contacts also insufficient with temperature sensor, influences dry combustion method Judgement.Even if being used on the kitchen range of the flames of anger, since infrared sensor is face kitchen range, and in cooking process on kitchen range The pollution for being very easy to generate the impurity such as greasy dirt causes infrared sensor to lose quickly so that infrared sensor is easily got dirty Effect.

3. increasing infrared sensor at kitchen range center, cooking bottom temperature is detected by infrared ray, still, due to reality In cooking process, almost all covers flame around the bottom of a pan, causes infrared temperature sensor temperature obtained actually big Part is all the temperature of flame, rather than the temperature of cookware, causes the practicality little.

4. or more contact or non-contacting solution be all based on existing gas-cooker and reequiped, user if it is desired to solution Certainly dry combustion method problem has to buy gas-cooker again, and it is unfavorable that this solution for undoubtedly largely effecting on anti-dry is promoted.

5. the prior art due to can not to before kitchen range, whether someone is detected, cause its cannot be distinguished kitchen range temperature become Change is artificial origin or due to boilers from drying burning, to the case where often reporting by mistake when normal culinary art occur.

6. user, may be due to various emergency situations when being acted using kitchen range cooking, Baoshang or the other culinary arts of progress And kitchen away from keyboard of having to, Tathagata guest, it answers the call, receives express delivery etc., and when user is due to making off or leaving kitchen Between it is too long and forget close fire, lead to boilers from drying burning.More serious, cookware may be burnt, and the carbide in cookware connects with fire Touching is ignited, to cause fire.

Therefore, a kind of to replace gas-cooker without user, but whether the method for dry combustion method just seems especially intentionally energy accurate judgement Justice.
