Electric kettle

Abstract

The invention relates to the technical field of household appliances, in particular to an electric kettle. The electric kettle comprises a kettle body, an inner container is arranged in an inner cavity of the kettle body, and a heating device is arranged at the bottom of the inner container; a steam passage is formed between the kettle body and the inner container, the bottom end of the steam passage is located in the heating device, and the steam passage is used for driving an elastic metal piece of a power supply switch of the heating device to cut off power supply for the electric kettle; acavity is formed in the top of the kettle body and located above the steam passage, the top of the steam passage penetrates into the cavity, and an air inlet communicated with the inner cavity of thekettle body is formed in the cavity and is higher than the top end of the inner container in height, and the top end of the steam passage is higher than the air inlet in height. According to the electric kettle, the foreign body sensation does not exist, and the electric kettle is more attractive; the backward flowing phenomenon cannot occur; the whole inner container can be used for containing water, the utilization rate of the inner container is higher, compared with the prior art, the inner container of a smaller height can be used for containing the same amount of water, and the purpose of reducing cost is further achieved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an electric kettle. Background technique [0002] Because the electric kettle has advantages such as easy to use, safety and reliability, it has been widely used in daily life. There are many ways to automatically power off the electric kettle, among which, using steam to power off is one of the common ways. [0003] The electric kettle includes a steam channel. When the water in the inner tank is boiled, a large amount of steam will be generated. The steam will be squeezed into the steam channel due to the pressure difference between the internal environment of the kettle and the atmospheric pressure. The bottom of the steam channel is aligned with the temperature sensor. The component, that is, the metal shrapnel, is heated and deformed, thereby triggering the power switch to achieve the purpose of automatic power-off. [0004] There are two main ways to set up t...

Problems solved by technology

[0004] There are two main ways to set up the existing steam channel, one is to place the steam channel in the inner tank, such as figure 1 As shown, the top of the steam channel 1' is higher than the highest water level line of the inner tank 2'. In this form, the steam channel 1' is exposed to the outside, which is not conducive to the cleaning of the inner tank 2', and brings a foreign body feeling to the user and affects the appearance; the other It is to hide the steam channel between the inner tank and the outer cavity of the kettle, such as figure 2 As shown, the top of the steam channel 1' communicates with the inner tank 2'. In this form, when water is added to the inner tank 2', water is easily added to the steam channel 1' by mistake, causing backflow, and the top of the steam channel 1' protrudes Parts are also easy to see, which affects the appearance. The space reserved for the steam channel 1' between the inner tank 2' and the outer cavity of the kettle will restrict the size of the inner tank 2', resulting in a reduction in the capacity of the inner tank 2', and further The only way to increase the capacity of the inner tank is to increase the height of the inner tank by 2', resulting in an increase in the cost of the electric kettle

[0005] In the above two steam channel arrangements, the highest water level of the inner tank 2' is lower than the top of the inner tank 2', that is, due to the existence of the entrance of the steam channel 1', the highest water level of the inner tank 2' reaches the inner tank 2 'The top part can't be practically applied, but this part can't be canceled, so the cost of the electric kettle can't be reduced
