Embodiment 1

[0040] This example is a thermostat electric kettle, such as figure 1 , 2 , 3 and 4, including base 10, kettle body 20 placed on the base, kettle lid 30, electric heating plate 40 placed in the kettle body, electric control device 50 and heat dissipation device 60 placed in the kettle lid. The kettle body is movably placed on the base, the kettle body bottom is provided with a power connector 21, and the base is provided with a power socket 11, the power connector 21 and the power socket 11 can adopt the prior art, when the kettle body is placed on the base, the power connector 21 can be easily inserted in the power socket 11 on the base, and connect the power supply in the kettle body. The wall of the kettle body 20 is a sandwich structure, and the interlayer is evacuated; the bottom plate 31 of the kettle cover 30 is made of heat-insulating material, and the opening of the kettle body is fully covered during work; the electric control device 50 includes a control circuit boar...

Embodiment 2

[0054] Another kind of kettle lid 30 cut-away enlarged schematic diagram of this example temperature-regulating electric kettle is as Figure 5 As shown, this example is basically similar to Example 1, the difference lies in:

[0055] The radiating fins 61 are movable fins 61b, the edge of which is provided with a heat conduction lip 61b1, and the movable fins 61b are movably installed in the lid 30, and can be driven by a driving device 64 to move along the guide rail 66 to make the heat conduction lip 61b1 is inserted into or extracted from the gap between the upper end of the kettle body 20 and the lower edge of the kettle cover 30 to realize communication or cut off the heat conduction between the movable fin 61b and the inner wall of the kettle body 20 . When the heat-conducting lip 61b1 is inserted into the gap between the upper end of the kettle body 20 and the lower edge of the kettle cover 30, it will be in close contact with the upper end of the kettle body 20. Becau...

Embodiment 3

[0057] This example Figure 6 , 7 As shown, basically similar to example two, the cooling fin 61 of this example is also a movable fin 61b, which is movably installed in the pot lid 30 and can move along the guide rail 66; the difference with example two mainly lies in:

[0058] The heat-conducting element 63 is a cylindrical panel 63b, which is cylindrical and fixed in the pot body 20. The middle and lower parts are immersed in the water in the pot, and the upper part extends into the pot lid, and the movable fin 61b is driven by the driving device 64. Move, make its edge and column plate 63b contact each other or separate from each other, their contact surfaces have the shape that fits each other, fin and column plate 63b are made of good thermal conductivity material such as aluminum alloy, copper alloy. The end portion of the movable fin 61b is fixed with an insulating cover 67 for preventing heat radiation. In the heat preservation state, the edge of the movable fin 61b ...

Abstract

The invention discloses a temperature-adjusting electric kettle, and relates to an electric kettle for home use. The electric kettle is used for boiling water and for conducting rapid cooling and long-time heat preservation. The electric kettle comprises a base, a kettle cover, a kettle cover, an electric heating tray, an electric control device, a heat radiating device and a driving device, wherein the electric control device comprises a control circuit board, a control panel and a temperature sensor; the heat radiating device comprises heat radiating fins, a heat radiating fan and a heat-conductive element; and in a mode of driving the heat-radiating fins or the heat-conductive element by virtue of the driving device, switching between water heat conduction and an insulating state in theheat-radiating fins and the kettle body is achieved. The wall of the kettle body is of a jacketed structure; and the interior of the jacket is vacuumized. By virtue of the temperature sensor, commands are transmitted to the control circuit board, so as to achieve working procedures of heating and boiling water, forcibly and rapidly cooling boiling water, insulating water temperature which is setfor a long time and compensating heat and heating-up; shortcomings of existing electric kettles which cannot conduct rapid cooling and cannot preserve heat for a long time can be overcome; user's timeof waiting for natural cooling-down of the boiling water can be shortened, and electric energy of repeatedly conducting boiling can be also saved; and meanwhile, harm of 'thousand-boiling water' to people's health can be avoided.

Description

[0001] manual technical field [0002] The invention relates to an electric kettle for domestic use, in particular to an electric kettle capable of maintaining a set temperature for preparing boiling water for drinking. Background technique [0003] Electric kettle is a kind of device that is widely used in family and public places to prepare drinking boiling water. The electric kettle in the prior art includes kettle body, kettle lid, electric heating plate and steam switch placed in the kettle body. When the water is heated to the boiling point, the A large amount of water vapor close to the boiling point temperature triggers the steam switch to cut off the power supply of the electric heating plate and stop working. Although electric kettles are widely used, there are still some defects. For example, the boiled water will slowly cool down to close to room temperature when left in the kettle, which does not meet the needs of Chinese people for making tea and drinking hot d...
