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.

The invention provides a coffee machine, aiming at solving the problem of low heating efficiency of the heating device of the coffee machine in the prior art. The coffee machine comprises: a fuselage;A water tank capable of being placed on the fuselage and for providing water to be heated; A heating pipe mounted within the fuselage and for heating water supplied from the water tank; And an infusion chamber for containing coffee powder and for receiving hot water heated through the heat pipe for infusion of the coffee powder by the received hot water. The heating pipe includes a water inlet, awater outlet, and a heating pipe arranged between the water inlet and the water outlet. The heating pipe has a heating film on the outer side, and the heating film is capable of heating to heat the water flowing through the heating pipe when the heating film is energized. The heating tube of the coffee machine 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 invention relates to the field of electrical appliances for brewing coffee beverages, in particular to a coffee machine. 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] Such as figure 1 As shown, it is a cross-sectional schematic diagram of a prior art coffee machine, which is disclosed in China Utility Model Patent Application No. 2010205539...
