Electric kettle and its lid assembly

Abstract

The invention provides an electric kettle and a lid assembly thereof. Among them, the kettle lid assembly is provided with a steam channel, and a rotating anti-overflow assembly is provided in the steam channel. The rotating anti-overflow assembly includes: a rotating valve body and a rotating weight. The rotating valve body is rotatably installed in the steam channel. The rotating valve body There is an exhaust channel in airtight communication with the steam channel, and the exhaust channel is connected with a rotation axis that moves away from the rotary valve body. The exhaust pipe has a protruding direction; the rotating weight is installed on the rotating valve body and is set opposite to the exhaust pipe. The rotating weight can rely on its own gravity to drive the electric kettle when it is tipped and the tilting angle is not greater than 90°C. The exhaust pipe rotates upward so that the steam outlet of the exhaust pipe is higher than the highest pouring liquid level in the electric kettle. The above technical solution can not only effectively prevent the water in the electric kettle from overflowing when the electric kettle is tipped, but also prevent the steam channel from being sealed to ensure the normal discharge of steam in the kettle and ensure the safety of the use of the electric kettle.

Description

technical field [0001] The present invention relates to the field of household appliances, more specifically, to a lid assembly of an electric kettle and an electric kettle including the lid assembly. Background technique [0002] At present, the existing anti-overflow safety electric kettle usually adopts a sealed assembly method between the lid and the body of the kettle to prevent the hot water in the kettle from overflowing and scalding people after the kettle is accidentally dumped. For the steam discharge channel and the temperature control switch steam channel, most electric kettles are installed in the sealing cover of the kettle by means of a heavy hammer (the most common shape is a spherical, axisymmetric round table and other rotating parts), and the weight is used to dump it. The exhaust channel is sealed in a way that the displacement occurs in time to prevent the water in the pot from overflowing. [0003] However, the heavy hammer is not tightly sealed or the...

Problems solved by technology

[0003] However, the heavy hammer is not tightly sealed or the vent hole cannot be sealed in time, or the water is drained at the seal or the pressure relief hole due to excessive internal pressure of the kettle, which can easily lead to water leakage in the kettle, and the anti-overflow effect of dumping is poor; The heavy hammer sealing scheme, after the kettle is poured, the interior of the kettle will continue to heat for a short time due to thermal inertia, which will lead to high internal pressure of the kettle, especially when the lid is opened halfway and then closed and poured, because when pouring The heavy hammer seals the exhaust port, so that the cold air entering the kettle is heated, causing the pressure inside the kettle to increase instantaneously and the lid is washed away, which brings safety hazards
