Abstract
The utility model discloses an automatic temperature control system of an electric heating kettle, comprising a first temperature control system, a relay, a heating tube, a first temperature detector arranged at a kettle bottom, as well as a second temperature control system and a second temperature detector arranged at the upper part of a kettle body, wherein the first temperature detector and the relay are respectively connected with the first temperature control system; the relay is also connected with the heating tube; and the second temperature detector is connected with the second temperature control system which is connected with the relay. The automatic temperature control system has the advantages of being capable of measuring the temperature of the kettle bottom and the temperature of the water vapor simultaneously, thus guaranteeing the use safety, and simultaneously, having the functions of self locking and capability of recovery, and further preventing the damage to the kettle caused by unexpected operation.
Description
Technical field
The utility model relates to a kind of temperature control system, specifically, relates to the electric kettle auto temperature controlled system.
Background technology
Electric kettle has had increasing family using, and it heats soon, heats up water conveniently, its temp measuring system adopts the bimetal leaf thermometric, this technology is applied for a patent by external personage, and China uses this technology all to need to pay certain usage charges now, and cost of goods manufactured is strengthened.So someone expects using the NTC thermal detector, but only being provided with the anti-dry thermal detector at the bottom of kettle, can measure by the electric kettle of existing employing NTC thermal detector water temperature, can't measure for the temperature of steam.
The utility model content
The purpose of this utility model is to provide the electric kettle auto temperature controlled system, can effectively solve the problem that existing electric kettle can not be simultaneously measured temperature at the bottom of the kettle and steam temperature.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: the electric kettle auto temperature controlled system, comprise first temperature control system, relay, heat-generating pipe, be arranged on first thermal detector at the bottom of the kettle, described first thermal detector is connected with first temperature control system respectively with relay, described relay also links to each other with heat-generating pipe, also comprise second temperature control system, be arranged on second thermal detector on kettle body top, described second thermal detector links to each other with second temperature control system, and described second temperature control system links to each other with relay.
Preferably, also be provided with self-locking system between described first temperature control system, second temperature control system and the relay; Prevent that further accidental operation from making heat-generating pipe work cause damage to the kettle body.
Preferably, described self-locking system is provided with the recovery switch; Conveniently self-locking system is carried out recovery operation.
Preferably, also comprise dc source, described dc source links to each other with first temperature control system, and described dc source links to each other with second temperature control system; Utilize low-voltage that control system is powered.
Preferably, described first thermal detector adopts the NTC thermal detector; Described second thermal detector adopts the NTC thermal detector; The NCT thermal detector is exactly the thermal detector that adopts negative temperature coefficient thermistor, compares the purpose that reaches control circuit by negative temperature coefficient thermistor resistance value obvious variation under the different temperatures and predefined resistance value.
Compared with prior art, the utility model has the advantages that: can measure temperature at the bottom of the kettle and steam temperature simultaneously, guarantee safe in utilization, but have self-locking and restore funcitons simultaneously, prevent that accidental operation from causing damage to kettle.
