Problems solved by technology

Its anti-dry function can only be controlled by KSD thermostat or NTC temperature sensor
201110165035.7 announced that a cylindrical PCB board is installed in the pot to detect the water level. The pot is not easy to clean after installing this device, and the corroded PCB board material also pollutes the water quality. The number of detection points set will inevitably increase. Wiring ports, breakaway connectors not suitable for cordless electric kettles
[0003] In practical application, in order to add water conveniently, the tea maker that combines a cordless electric kettle and a water pump can only add water manually because there is no water level detection device.

Embodiment Construction

[0021] When the PCB water level does not detect the resistance of the resistor (17), it means that the upper connector (8) and the lower connector (9) are not coupled or in poor contact; the water surface in the pot is lower than the water level electrode (6) PCB water level detection only detects the resistance (17) When the resistance value indicates water shortage, the connector has been properly coupled; when the water surface in the pot exceeds the water level electrode (6), the water level electrode (6) and the ground wire (13) form a loop, and the PCB water level detects a change in the resistance value. There is water in the jug and the connectors are properly coupled.

Abstract

A water level detection and installation method for a cordless electric kettle, which is characterized in that the water level electrode wrapped by silica gel or other insulator materials is installed on the bottom or side of the kettle body, the NTC circuit and the water level electrode wire share a connection port of the connector, and the power supply is grounded The wire and the PCB water level detection incoming wire share a connection port of the connector, and the water level electrode wire connection port of the upper connector and the ground wire connection port are connected by resistance. An anti-dry device is added to the cordless electric kettle to provide a technical premise for automatic water addition.

Description

technical field [0001] The invention relates to an improvement of a kettle, in particular to an improvement of a method for detecting and installing a water level applied to a cordless electric kettle. Background technique [0002] At present, the cordless electric kettle connected by a connector is already a practical electrical appliance for boiling water and making tea. Because of its low cost and the separation of the power cord and the kettle body, it is easy to use and is loved by people. The base contains the power cord and the PCB board control circuit. The common five-pin connector on the market can only provide connections for the positive and negative poles of the heating tube at the bottom of the pot, the ground wire, and the two end wires of the NTC temperature sensor. Limited by the structure of the connector connection, the cordless electric kettle has no simple method for detecting the water level for the time being. Its anti-dry function can only be control...
