Description

A kind of kitchen range with non-contact sensor device

Technical field

The utility model is related to a kind of kitchen range, especially a kind of kitchen range with non-contact sensor device.

Background technology

All the time, people pay special attention to the security of gas kitchen ranges, so generally can all be set in gas-cooker Various protection devices.Gas-cooker using in the middle of process, the fortuitous event such as flame runs into wind or boiling water overflows and when extinguishing, Combustion gas can be caused to leak, so that trigger security incident, therefore, introduce cooking bottom temperature sensing device and seem very necessary, can keep away Exempt from dry combustion method, empty burning, and better control over firepower size to coordinate various cooking process.

Current existing gas kitchen ranges to technologies such as the monitorings of pan temperature monitoring and pan use state using few, i.e., Make to have using being also directly to carry out contact measurement to the bottom of a pan using mechanical contact structure, such mode is in use Error is larger, and flame disturbs severity to it, it is prolonged using the probe for accelerating to be contacted with the bottom of a pan it is aging the problems such as.Contact temperature Degree sensor also brings greater impact to cleaning.

Therefore, also there has been the mode of some non-contact detectings, such as Chinese patent of Application No. 201110083272.9 A kind of disclosed automatic temperature controlled gas cooker and temperature control method, temperature-sensing element, including thermometric sense are provided with the center of burner Coil and magnet exciting coil are answered, pot bottom of cooking is provided with magnetic induction intensity corresponding with magnet exciting coil to be changed according to temperature change Magnetic temperature-sensitive element, magnet exciting coil carries out excitation to thermometric induction coil, between thermometric induction coil and magnetic temperature-sensitive element A temperature-sensitive detection magnetic field is formed, for the magnetic signal that magnetic temperature-sensitive element is produced at different temperatures to be converted into electric signal simultaneously Output, to detect the temperature of boiler.What above-mentioned this mode was detected is not the direct temperature of pan bottom, it is necessary in the bottom of a pan Increase device, and the temperature-sensing element is disturbed by flame, and temperature deviation is very big.

And for example a kind of touch-key intelligent gas-burning stove disclosed in the Chinese patent of Application No. 201410175957.X, incites somebody to action Non-contact Infrared Temperature Measurement module is installed under gas-cooker chassis, the circular hole that probe passes through Zao Yan centers, direct detection to the bottom of a pan The temperature of center.Above-mentioned this mode, can only detect the temperature in the bottom of a pan, and function is relatively simple, and infrared measurement of temperature module Specific structure is had no with the mounting means of gas-cooker to disclose, and use conventional gas-cooker to be then difficult to this scheme.

Additionally, in order to prevent empty burning, and pollution, the deterioration kitchen environment to environment are caused, and also there are some schemes at present, lead to The state for setting pan whether there is on sensor detection cooking stove is crossed, so as to carry out automatic adjusting gas stove flame.Such as Application No. A kind of gas kitchen range flame disclosed in the Chinese patent of 201320536433.X automatically adjusts device, including infrared ray sensor, infrared The side of the metal pan on the line sensor probe alignment kitchen range top, during work, gas stove is detected by infrared emission, infrared receiver On whether have pot, when having pot, infrared ray sensor conducting, final control combustion flame becomes big, and when without pot, infrared ray is passed Sensor ends, and combustion flame is diminished.This gas-cooker, infrared ray sensor is arranged on the side of cooking stove, from lateral inspection The presence or absence of survey pan state, but such detection mode, infrared signal are easily disturbed by flame, cause the result of detection There is deviation；Further, since the size of pan, different, it is inclined when lateral detection not only easily to cause that testing result occurs Difference, it is easier to error detection occur, and be easy to be disturbed by other objects, also have very high to the position of sensor It is required that, and the setting of sensor to the process of culinary art it could even be possible to make troubles.
