Rapid heating type liquid heating pipe

Abstract

The invention discloses a quick-heating liquid heating tube provided with a metal tube on which at least one axial water-flow channel is arranged and at least one axial heating wire mounting channel is arranged; one heating wire is arranged in each heating wire mounting channel; a heat conducting high-temperature-resistant insulation material is filled into the heating wire mounting channel and the peripheral region of the heating wire is covered by the insulation material; the water-flow channel is adjacent to but not communicated with the heating wire mounting channel, and the water-flow channel is integrated with the heating wire mounting channel; the metal tube is made of one-piece of metal provided with a better heat conductivity. The quick-heating liquid heating tube of the invention is provided with the integrated and adjacent water-flow channel and heating wire mounting channel, and then the isolating wall between the water-flow channel and heating wire mounting channel can be made to be so thin that the distance between the water-flow channel and the heating wire mounting channel can be shortened; the heat conducting loss can be reduced; the heat conducting efficiency can be enhanced and the service life of the heating elements can be prolonged.

Description

technical field [0001] The invention relates to a fast heating tube for liquid, in particular to a liquid heating tube for electric heating equipment such as a coffee pot. Background technique [0002] The key liquid heating components of the existing electric coffee machines, electric water dispensers and other liquid heating beverage making machines sold in the international market usually take the following form: [0003] 1. Hot water boiler (also known as hot water tank), its structure and function principle are: an electric heating tube is installed in the sealed cavity of a metal pot body, and the water in the cavity is heated and then sent to make drinks. The disadvantages are: [0004] (1) Poor safety: Once the thermostat of the boiler or heater is out of control or damaged, the boiler is prone to explosion. [0005] (2) Long heating time: the boiler needs a long heating time due to its large volume and large water storage, resulting in that there is always a pot o...

Problems solved by technology

[0004] (1) Poor safety: Once the thermostat of the boiler or heater is out of control or damaged, the boiler is prone to explosion

[0005] (2) Long heating time: Due to the large volume and large water storage of the boiler, it takes a long time to heat up, resulting in a pot of unused hot water in the boiler every time a drink is brewed, which is wasted

[0006] (3) The water quality is easy to deteriorate: because the remaining water in the boiler cannot be discharged, this part of the water will be heated repeatedly, resulting in poor water quality, and long-term drinking is harmful to human health

[0008] Since the heater is connected as a whole by the water pipe component and the heating pipe component through mechanical fastening connection or casting and welding, and the heating pipe is made of heterogeneous iron material, the heat transfer between the heating pipe and the water pipe is directly transferred to the real body. There is still a big gap, and the heat transfer efficiency needs to be further improved and improved
