Substance (such as water, rice etc.) in device and pot gallbladder is intermediate across a pot gallbladder, so the temperature in actually measured temperature and gallbladder is
Discrepant, when substance is rice in gallbladder when special, rice can be deposited in a pot gallbladder bottom, and at this moment the temperature sensor outside the bottom of a pan will be every
The beds of precipitation of pot gallbladder and rice go to measure the water temperature in pot indirectly, this can be to the very big error of measurement band.Most of electric heater
Tool is all accordingly to be controlled according to the water temperature in container, so how to accurately measure the water temperature in container is all kinds of electricity
One of the key technology of hot utensil.
The common method for solving this problem is using top temperature measurement.Temperature transducer or circuit are placed in the top cover of container
On, such sensor device can be directly facing the water surface in electric heater container, and blocking for intermediate not solid matter can measure
More accurate coolant-temperature gage.But this mode needs to have electrical connection between top cover and electric heater, to give the circuit or biography of top cover
The signal measured is transmitted to the control circuit of electric heater for electric power and by line by sensor.Since the top cover of electric heater is mostly to live
Dynamic component, and how much being separated with electric heater greatly, in this way in structure or the reliability of work, all exist
Some problems, so that the use of this mode is limited, so actually rare in actual products.
Summary of the invention
The technical problem to be solved in the present invention is that for the defects in the prior art, providing a kind of thermometric of electric heating appliance
Device and method, the temperature measuring equipment and method of fast electric heating appliance of the invention, top cover do not need to have with electric heater with any
Line connection can carry out reliable top temperature measurement, it may be convenient to by design of cover at active type or divergence type.Simultaneously as half
Conductor thermoelectric generation film does not need to replace, so entire circuit can accomplish good waterproof seal, substantially increases work
Reliability and durability.
Its technical solution is as follows:
A kind of temperature measuring equipment of electric heating appliance, which is characterized in that including semiconductor temperature differential power generating sheet, voltage regulator circuit, thermometric

It is connect with temperature measurement circuit.
Inside of the hot end of the semiconductor temperature differential power generating sheet towards container, cold end is towards outside.
A kind of temp measuring method of electric heating appliance, with the rising of container internal temperature, is placed in when electric heating appliance work
The temperature difference at the semiconductor temperature differential power generating sheet both ends of top cover becomes larger, so that semiconductor temperature differential power generating sheet generates voltage, semiconductor temperature difference
The voltage regulator circuit progress pressure stabilizing that the voltage of power generation sheet output passes through, the power input of the voltage temperature measurement circuit 3 of voltage regulator circuit output,
Temperature measurement circuit is started to work after being powered, and measures the temperature in container, and the temperature data that will be measured by temperature sensor module
Pass through the control circuit for being wirelessly transmitted to electric heater of low-power consumption.
The wireless module is low-power consumption bluetooth communication module.
Temperature data measured by the temperature measurement circuit is sent to the control circuit of electric heating appliance by wireless module, control
Circuit makes corresponding control according to the temperature value received.
The control circuit can issue control instruction to temperature measurement circuit simultaneously.
Beneficial effect
The present invention has the following advantages compared with prior art:
1, using semiconductor temperature differential power generating sheet, it can use the inside and outside temperature difference when work of hot spot utensil as measurement electricity
Road provides electric power.
2, measurement data is sent using wireless mode, avoids the wired connection between measuring circuit and control circuit, greatly
The placement of measuring circuit is facilitated greatly, and the entire top cover of electric heating appliance does not need have any wired connection that can carry out with electric heater
Reliable top temperature measurement, it may be convenient to by design of cover at active type or divergence type；
3, simultaneously as semiconductor temperature differential power generating sheet does not need to replace, so entire circuit can accomplish good waterproof
Leakproofness substantially increases the reliability and durability of work；
