Electric kettle with modified temperature control device

Abstract

The invention relates to an electric kettle with a modified temperature control device. The electric kettle comprises a kettle body, a heater and the temperature control device connected with the heater through a circuit. The electric kettle is characterized in that the temperature control device comprises a temperature sensor mounted in a kettle steam area, a thermostat connected with the heater, a power switch member and a mechanical transmission whereby the thermostat and the power switch are connected; the power switch member comprises a switch key connected with the mechanical transmission and a power switch connected with the switch key and the thermostat; an airtight seal structure preventing steam from entering the power switch or / and the thermostat is further disposed between the temperature sensor and the power switch member or thermostat. In this way, during using, the steam can be prevented by the airtight seal structure from entering electronic components of the power switch member and the thermostat thereof from a steam switch, and sensitivity and application safety of the electronic components of the temperature control device are ensured; no steam water flows out of the bottom of the kettle, so that the kettle is clean to use.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to an electric kettle with an improved temperature control device. Background technique [0002] Most of the current electric kettles (including coffee pots for boiling water) are provided with a heating device at the bottom of the pot body, a thermostat connected to the heating device, and then a thermostat connected to the bottom of the pot or on the handle. A power switch and a steam switch (also called a temperature sensor) used to control the circuit on and off of the electric heating device, and the steam switch communicates with the inside of the pot through the steam channel. However, when the steam switch is arranged at the bottom of the kettle body, since the steam switch introduces the steam in the kettle into the temperature-sensing head at the bottom of the kettle body through the steam channel vertically installed in the kettle body, and then passes through the hea...

Problems solved by technology

However, when the steam switch is arranged at the bottom of the kettle body, since the steam switch introduces the steam in the kettle into the temperature-sensing head at the bottom of the kettle body through the steam channel vertically installed in the kettle body, and then passes through the heat-sensitive bimetallic sheet (steam temperature-sensing sheet) ) and the power switch (generally a touch switch) in the power switch part to realize the automatic power-off when the power switch pulls the lever to trip when the set temperature is reached, although this kind of temperature control device that combines the steam switch and the thermostat is relatively easy to install , but there are many disadvantages caused by the introduction of water vapor into the bottom of the kettle. First, because the thermostat and power switch are often exposed to water vapor, the electronic components of the power switch are damp, resulting in a decrease in the sensitivity of the thermostat and power switch electronic components. Short life, unsafe use and other problems; second, the steam water accumulated at the bottom of the pot often flows out, which affects the cleanliness of the use environment; third, the water level in the pot should not be too high to prevent water from directly entering the steam channel and affecting the thermostat It is safe to use and make the water flow out of the bottom of the pot, so the electric kettle with this structure is difficult to meet the requirements of consumers

And when the steam switch is contained on the kettle handle, because the electronic element (power switch) on the existing power switch part will be connected with the thermostat circuit at the bottom of the kettle by electric wire, just can make steam switch when pressing The circuit can be connected to work normally and the circuit can be disconnected when the set temperature is reached. The kettle with this kind of split temperature control device also has the influence of moisture on the power switch and wiring terminals and the circuit connection caused by the water vapor entering the handle through the steam channel.
