Description
Technical field
The utility model relates to a kind of water temperature and water level measuring and controlling circuit of kettle teapot, the water temperature and the water level measuring and controlling circuit of the kettle teapot that particularly a kind of and electromagnetic oven is supporting.
Background technology
Boil water with electromagnetic oven and in current family life, to have obtained very general application, electromagnetism drinking water boiler particularly, being used for specially heats up water makes tea. need to solve but exist some problems: on the one hand, because the temperature that common electromagnetic oven can only be tested boiler face, and the water temperature in the temperature of boiler face and the kettle is to exist very big difference, and the water yield in kettle is many more, and this difference is just big more.So common electromagnetic oven generally can not be merely be judged according to the temperature of test boiler face whether water has boiled,, use very inconvenient so must judge the water back manual-lock electromagnetic oven that boils by the user.On the other hand, whether water is arranged in the kettle, common electromagnetic oven can't judge, as long as there is kettle to be placed on the boiler face, electromagnetic oven is heating automatically just.If when anhydrous empty kettle was put on the boiler face, it also can heat automatically.This not only causes the waste of resource, also might burn out kettle, causes unexpected accident, even damages electromagnetic oven.Therefore design the water temperature of the water in the kettle teapot that can accurately detect on the electromagnetic oven and the telemetry circuit of water level, be very important.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, for people provide the water temperature of water in a kind of kettle teapot that can accurately detect on the electromagnetic oven and the telemetry circuit of water level, electromagnetic oven is judged automatically: when not heating when anhydrous in the kettle; When water boils in the kettle, stop heating, thereby realize the intellectuality that electromagnetic oven is heated up water.
In order to realize above-mentioned this purpose, can adopt following technical scheme: the telemetry circuit of the technical program comprises:
One is contained in the water temperature on the kettle teapot and the test and the data radiating circuit of water level, this radiating circuit comprises: one is contained at the bottom of the kettle teapot kettle or the induction coil of kettle side, the output of this induction coil is connected with the input of power supply rectifier and voltage regulator circuit, and this power supply rectifier and voltage regulator circuit is output as whole testing circuit power supply is provided; Be connected with the input interface of MCU again after also having one to be contained in the interior temperature probe of kettle teapot and the temperature test circuit is connected; In addition, also have one be contained in the kettle teapot near the water-level probe at the bottom of the kettle be connected with another input interface of MCU again after the water level test circuit is connected; The output interface of this MCU is connected with an infrared emission circuit, and this infrared emission circuit is outwards launched corresponding data-signal by an infrared emission head;
A data-signal receiving circuit that is connected with the control circuit of electromagnetic oven, this digital signal receiving circuit comprises the MCU of an infrared receiving terminal and a control electromagnetic oven, the MCU of this electromagnetic oven is connected with the control circuit of electromagnetic oven, charactron in the control circuit of this electromagnetic oven shows the water temperature in the kettle teapot, after water boils, the MCU of this electromagnetic oven control electromagnetic oven is closed and is stopped heating, and when in the kettle when anhydrous, the MCU control electromagnetic oven of this electromagnetic oven is disconnected promptly and do not heated.
The operation principle of above-mentioned telemetry circuit is: after opening electromagnetic oven, kettle teapot is placed on the electromagnetism stone or metal plate for standing a stove on as a precaution against fire, the magnetic field of the induction coil inductive electromagnetic stove in the test of water temperature and water level and the data radiating circuit produces alternating current, this alternating current by power supply rectifier and voltage regulator circuit become appropriate voltage, the galvanic current source, this dc source is for providing power supply for whole testing circuit.
Water-level probe is sent into signal among the MCU by the water level test circuit after testing water level in the kettle, and MCU is converted to data signal by digital-to-analogue conversion with water level signal, by infrared emission circuit drives infrared emission head, waterlevel data is sent then.Infrared receiving terminal receives and is installed in the infrared data signal that the telemetry circuit on the kettle body is launched, and sends the MCU of electromagnetic oven after handling by amplification to.
Cross when low or anhydrous when electromagnetic oven MCU determines the water-in-kettle position, will send instruction to the electromagnetic oven control circuit, circuit is disconnected promptly and is not heated; When detect the water-in-kettle position normal after, then send instruction to the electromagnetic oven control circuit, connect circuit and promptly begin heating.
Water temperature probe is sent into signal among the MCU by the water temperature test circuit after testing water temperature in the kettle, and MCU is converted to data signal by digital-to-analogue conversion with water temperature signal, by infrared emission circuit drives infrared emission head, the water temperature data is sent then.Infrared receiving terminal receives and is installed in the infrared data signal that the telemetry circuit on the kettle body is launched, and sends the MCU of electromagnetic oven after handling by amplification to.
When electromagnetic oven MCU whenever receives a temperature value, just this temperature value is shown by the charactron on the electromagnetic oven.When detecting a certain temperature value in the time in appointment when invariable, show that then water has seethed with excitement, the MCU of electromagnetic oven sends instruction to the electromagnetic oven control circuit, stops heating.
From above analysis as can be seen, the utility model has the advantages that, existing electromagnetic oven and kettle teapot are increased the circuit part according to the technical solution of the utility model, then can realize the intellectuality that electromagnetic oven is heated up water, promptly detect the water level and the water temperature of water in the kettle teapot on the electromagnetic oven exactly, and electromagnetic oven can be judged automatically: when not heating when anhydrous in the kettle; When water boils in the kettle, stop heating.It can be widely used in electromagnetic oven and heat up water in the equipment of infusing tea.
