Energy-saving kettle

Abstract

The invention discloses an energy-saving kettle. The energy-saving kettle comprises a kettle body, a kettle cover and a kettle handle, the kettle cover is rotationally connected to the top of the kettle body, a telescopic barrel is arranged in the kettle body, the top of the telescopic barrel is connected to the kettle cover, the bottom of the telescopic barrel is connected with the bottom of thekettle body through an elastic piece, a channel for water in the telescopic barrel to flow out is formed in the kettle cover, the bottom of the telescopic barrel is connected with a sliding block capable of moving up and down outside the kettle body, and the states of the sliding block, the telescopic barrel and the elastic piece are configured as follows that: when the elastic piece is in a natural state, the telescopic barrel is in a stretched state, and the sliding block is located at the highest point, and when the sliding block is located at the lowest point, the telescopic barrel contracts into the kettle cover, and the elastic piece is in a stretched state. A heater and a heat exchanger which are connected with each other are arranged in the kettle cover, and the heat exchanger is respectively communicated with the kettle body and the telescopic barrel through pipelines. The invention has the advantages of saving energy consumption and reducing heat loss.

Description

technical field [0001] The invention relates to the technical field of kettles, in particular to an energy-saving kettle. Background technique [0002] Small electric kettles have become a must-have electrical appliance at home. The basic heating principle of the electric kettle is to heat the water with the electric heating wire after the power is turned on, and the water temperature gradually rises to 100 degrees in about 5 minutes. heating. In the process of using an electric kettle to boil water, part of the heat absorbed by the kettle is dissipated in the air when it is transferred to the water, and as the water temperature gradually rises, the temperature difference between the water and the environment gradually increases, and the kettle material is an excellent heat conductor , which makes the water dissipate part of the heat in the air through heat conduction. [0003] At present, the more common method is to do anti-scald treatment on the outer layer of the kett...

Problems solved by technology

For example, the patent specification whose publication number is CN103431757B discloses a heat exchange type three-compartment energy-saving electric kettle, which includes a kettle body, a kettle cover, a handle and a spout. Each chamber is sequentially from top to bottom a cold water chamber, a heating chamber and a heat exchanging chamber; the heat exchanging chamber is also provided with a water outlet communicating with the spout; Heat insulation boards are respectively arranged between the heat exchange chambers, and electromagnetic valves are provided on the heat insulation boards; heat conduction rods are also included, and the heat conduction rods pass through the cold water chamber, the heating chamber and the heat exchange chamber in sequence; The heat-conducting rod in the heating chamber is also wrapped with a heat-insulating sleeve; there is also a heating device in the heating chamber, but this solution leads to a very low space utilization rate of the kettle, and only one-third of it can be used each time. Space, the kettle is not light enough
