Description
Technical field
The utility model relates to a kind of equipment that is used for adding hot water, more specifically to a kind of improved electric kettle.
Background technology
The electronic component of existing electric kettle all is installed in the nearer position of kettle body distance from bottom heater circuit, therefore electronic component is subjected to the heating radiation of heater circuit (being generally heat-generating disc) easily, continual performance and the quality that influences electronic component, reduced the service life of electronic component, if heater circuit is often overheated, the infringement that electronic component is subjected to is just more obvious.
As Chinese patent literature CN2862906 " electric kettle of structure of controlling temperature ", electric kettle, comprise the kettle body, on the bottom surface of kettle body, be provided with electric heater, on the bottom surface of kettle body, be mounted to rare two dry heating temperature controllers independently near the electric heater position, support is installed on the bottom surface, electric connector is installed on the support, dry heating temperature controller connects into control circuit by electric wire and electric heater and electric connector.
There is this shortcoming equally in this scheme: electronic component all is installed in the nearer position of kettle body distance from bottom heater circuit, electronic component is subjected to the heating radiation of heater circuit (being generally heat-generating disc) easily, and the performance of electronic component, quality and service life all decline to a great extent.
Summary of the invention
The purpose of this utility model is that prior art is improved, and a kind of improved electric kettle is provided, and can reduce the influence of heater circuit to electronic component, and the technical scheme of employing is as follows:
Improved electric kettle of the present utility model, comprise kettle body, pot lid, be located at heater circuit, detector unit in the kettle body and the control circuit that is electrically connected with heater circuit, detector unit respectively, it is characterized in that: described heater circuit all is connected the three-pin plug that can connect external power supply by five line couplings with control circuit.General electric kettle electronic component all is installed on the kettle body bottom, adopt five line couplings to be installed in electronic component on the power supply base, significantly increased the distance between electronic component and the heater circuit, make electronic component not be subjected to heat-generating disc heating radiation, therefore significantly reduced the harmful effect of heater circuit performance, quality and the life-span of electronic component.
Another purpose of the application is to utilize five wiring connectors to connect detector unit and control circuit, and described detector unit connects control circuit by five wiring connectors.General electric kettle all adopts three-way coupling to connect as energising, can not connect detector unit and control circuit, and this electric kettle adopts five line couplings on the basis of three-way coupling, can also connect detector unit and control circuit.
Described five line couplings comprise five line coupling plugs and the five line connector receptacles that cooperate with it, five line coupling plugs insert in the five line connector receptacles, external power supply is electrically connected heater circuit by five line coupling plugs and five line connector receptacles, and detection module is by five line coupling plugs and five line connector receptacles polyphone detector unit.
Described detector unit is a thermistor.Temperature controller can be adopted, also thermistor can be adopted.Detect the temperature of liquid in the kettle body with thermistor, no matter be the temperature of directly measuring liquid or measuring liquid by steam indirectly, because thermistor is faster to the reaction of temperature, can boil the back at liquid and just can pass the signal to control module in 10 seconds, automatically outage, thereby reach power saving timesaving purpose, also can reduce the overheated possibility of heater circuit, further reduce the harmful effect of heater circuit performance, quality and the life-span of electronic component.
Described control circuit comprises input/output interface module, detection module, temperature control module, AD modular converter (analog-to-digital conversion module), control module and DA modular converter (D/A converter module), the backstage control device is delivered to control module by input/output interface module with the target temperature of input, detection module is measured the thermistor sampled voltage, after being converted to the determinand Current Temperatures, the AD modular converter is input to control module, control module comparison object temperature and determinand Current Temperatures, and corresponding heating of output or refrigeration magnitude of voltage, this magnitude of voltage is converted to analog quantity by the DA modular converter and outputs to temperature control module, and this temperature control module will be controlled electric current and deliver to heater circuit.
The utility model beneficial effect against existing technologies is, owing to adopt five line couplings, therefore can be installed in electronic component on the power supply base, make electronic component not be subjected to the heating radiation of heater circuit, can not influence the performance and the quality of electronic component, and can play the effect that connects detector unit and control circuit.
