Description
Technical field
The present embodiments relate to the thermometer of culinary art and electromagentic furnace technology fields, and in particular to a kind of wireless temperature measurement dress
It sets, wireless temperature measurement cooking pot and wireless temperature measurement pot and stove system.
Background technique
During food cooking, temperature is a critical factor.Currently, for cookware temperature in electromagnetic oven product
The conventional method of detection is that temperature sensor is installed below in the glass-ceramic panel of electromagnetism furnace top surface, this temperature sensor relies on
Elastic rubber seat is pressed on microcrystal glass plate lower surface.This mode has the disadvantage in that first, and temperature sensor detection is
The temperature of glass-ceramic panel, this temperature and the temperature of cookware itself have differences；Second, cookware is due to the original that makes or uses
Cause, may cause bottom surface and glass-ceramic panel can not tightly be bonded, this will lead to table on pan bottom and glass-ceramic panel
Face directly forms cavity, due to the presence of this cavity, the temperature sensor positioned at glass-ceramic panel lower surface is caused to detect
Temperature and the temperature of cookware itself form larger difference.Above-mentioned two reason, causing this temperature checking method, there are larger mistakes
Difference, according to actual measurement, this error can achieve tens degrees Celsius even more big.
For this problem, the method for having had already appeared radio detection cookware temperature, such as a kind of nothing in the prior art
Line boiler able to measuring temperature.The basic principle is that mounting temperature sensor and radio communication circuit on cookware, temperature sensor and cookware
It directly contacts, can detecte the true temperature of cookware, it then will be warm by the radio communication circuit on cookware by temperature data
Degree is sent to electromagnetic oven.In this way, need to solve the marriage problem of wireless temperature measuring device and electromagnetic oven.Due to channel radio
The signal of the characteristics of letter, the radio communication circuit transmitting on a cookware may be received by multiple electromagnetic ovens, each electromagnetism
Furnace needs identify the cookware being placed on this electromagnetic oven, and receive its temperature data.When multiple installation wireless temperature measuring devices
Cookware when being closer and working at the same time, electromagnetic oven and cookware should form the relationship matched one by one, avoid the mutual crosstalk of data.
The manual matching method of a kind of wireless temperature measuring device and electromagnetic oven is proposed in the prior art, in electromagnetic oven and wirelessly
Pairing button and indicator light are designed on temperature measuring equipment, while being pressed the starting of the button on electromagnetic oven and wireless temperature measuring device and being matched
Right, indicator light is used to refer to pairing state.Though this mode is able to achieve the pairing of wireless temperature measuring device and electromagnetic oven, when using
Frequently pairing by hand is needed, very inconvenient, if user forgets manual pairing, it will cause error in data, can draw when serious
Play the danger such as dry combustion method.The prior art proposes the matching method based on wireless temperature measuring device signal strength, and electromagnetic oven detection receives
The wireless signal strength for the wireless temperature measuring device transmitting arrived, is greater than the set value, is judged as pairing cookware.This mode is practical
In there are larger problems, the reason is as follows that.If multiple cookwares and electromagnetic oven equipped with wireless temperature measuring device work at the same time and electricity
Magnetic furnace close-packed arrays, apart from difference smaller, this range difference of some cookware apart from electromagnetic oven and adjacent electromagnetic oven where itself
Caused signal strength differences are very small；In addition, radio-frequency devices in the radio communication circuit of wireless temperature detector and electromagnetic oven
The dispersibility of energy parameter also can cause to significantly affect to the signal strength being an actually-received.Above two factor combines, it is likely that
So that the signal strength for itself cookware that some electromagnetic oven receives is lower than the signal strength of cookware on adjacent electromagnetic oven instead, this
It will lead to this method misjudgment.The prior art proposes a kind of matching method for repeatedly obtaining wireless temperature detector identification code,
The basic principle is that electromagnetic oven starts wireless temperature measuring device after detecting cookware needing with clock synchronization, it is made to send mark
Code, this process are repeated as many times, and electromagnetic oven can receive the identification code of multiple wireless temperature measuring devices in the process, then check
The multiple identification codes received are determined as wireless temperature measurement if wherein the ratio containing identical cookware identification code is greater than 50%
Cookware, successful matching.In this approach, if multiple adjacent multiple electromagnetic ovens start simultaneously at pairing or start the time of pairing
Closely, then the identification code of cookware is greater than than regular meeting on the adjacent electromagnetic oven that some electromagnetic oven receives during pairing
50%, pairing mistake is caused, if reattempting to pairing after multiple electromagnetic oven delay random times at this time, can be made multiple adjacent
The time that electromagnetic oven is fully completed pairing becomes too long, affects greatly to the actual use of product.
