Instant-heating type electric kettle

Abstract

The invention provides an instant-heating type electric kettle comprising a kettle body provided with a water tank, wherein, the outlet of the water tank is communicated with the faucet of the kettle body after the heat exchange is carried out by an electric heating element; the electric heating element is a quartz heating tube; the two ends of the quartz heating tube are communicated with the outlet of the water tank and the faucet of the kettle body respectively; the quartz heating tube is a hollow round tube, metal films are arranged at the two ends of the surface thereof and resistive films are arranged at the rest parts of the surface; an overheat protector is arranged on the outer surface of the quartz heating tube; a temperature sensor is arranged at the end communicated with the faucet and / or the outlet of the water tank; and a flow sensor is further arranged between the quartz heating tube and the outlet of the water tank. By using the non-conductive quartz heating tube for heating, the invention can realize the separation between water and electricity; meanwhile, by selecting the flow parameter of a water pump and the matched power parameter of a coated quartz-tube heating element according to the temperature of the outlet water, the water between the water pump and the coated quartz-tube heating element can be rapidly heated and discharged, thereby realizing the instant hot-water supply at the time that the electric kettle is live and overcoming the disadvantages that the existing water equipment has long pre-heating time and repeated heating process.

Description

technical field [0001] The invention relates to an electric kettle, in particular to an instant electric kettle. Background technique [0002] Traditional drinking water equipment boils a large amount of water at one time at the same time. The heating time is long, and consumers cannot get hot water immediately. Moreover, if the water is not used for a long time after boiling, it needs to be heated again when it is used again, resulting in repeated heating. Affect the quality of water, but also a waste of electricity. [0003] Chinese patent document CN201085481 disclosed an instant heating electric kettle on July 16, 2008, which includes a water tank in the kettle body. A heating plate assembly with a thick film circuit heating element is arranged in the kettle body. One end of the heating plate assembly passes through the water pump and the water outlet of the water tank. The other end is connected with the faucet arranged on the kettle body. The heating disc assembly in...
