Problems solved by technology

[0006] This heating device composed of heating tube 5 and U-shaped elbow 9 is a general electric heating tube (usually a resistance heating coil), because the bonding between the heating tube 5 and U-shaped elbow 9 is difficult to achieve In close contact and the part of the heat pipe 5 that is not in contact with the U-shaped elbow 9 is easy to dissipate heat, so its heating efficiency is low
In addition, since the heat generation and heat dissipation of the heat pipe 5 itself take a certain time, it is difficult to accurately control the temperature of the hot water provided.

Abstract

The invention provides a heating pipe, which aims at solving the problem of low heating efficiency of the heating pipe of a coffee machine in the prior art. The heating pipe comprises a water inlet, awater outlet and a heating pipe arranged between the water inlet and the water outlet. An outer side of the heating pipe has a heating film capable of heating when energized to heat water flowing through the heating pipe. The heating tube of the invention adopts a film heating technology, which has high heating efficiency and is easy to realize accurate temperature control.

Description

technical field [0001] The present invention relates to the field of electrical appliances used for brewing such as coffee beverages, and in particular to a heating pipe for heating water flowing therethrough. Background technique [0002] Along with the raising of people's living standard, coffee beverage begins to be liked by people, and becomes the daily drink of people especially those who pursue quality of life. The present method of making coffee beverages mainly includes: brewing with instant coffee, using existing coffee powder to brew in a coffee machine, and utilizing the coffee machine to grind coffee beans on-site and further brewing. [0003] The above-mentioned coffee machine usually has a heating device to heat the water flowing through the heating device, and pours the heated hot water onto the ground coffee to brew the coffee beverage. [0004] like figure 1 As shown, it is a cross-sectional schematic diagram of a prior art coffee machine, which is disclos...
