Problems solved by technology

[0002] At present, the drip coffee pot uses a U-shaped aluminum heating tube with a built-in heating wire as a heater. Due to its structural limitation, it is difficult to make a specification with a rated power exceeding 1000W, so its low power leads to long heating time and small water output. , and the outlet water temperature is uneven, the temperature of brewing coffee is not high; at the same time, because of the small contact surface between the heating part and the heat conduction part, the heat transfer efficiency is low, resulting in a large loss of heat energy generated by the heater, resulting in high energy consumption

Abstract

The invention discloses a rapid heating device. A spiral warming tube is used, the warming tube is embedded into the outer side wall of a heating tube made of aluminum alloy, and sufficient space is provided for increasing the rated power of the warming tube, so that the power of the warming tube can reach 1450 W, the heating time is shortened, and the coffee temperature is increased; meanwhile, the heat conduction area is increased through the structure, the heat energy of the warming tube can be fully absorbed by the aluminum alloy heating tube, the heat energy loss is reduced, the heating efficiency is improved, and the energy consumption is reduced.

Description

【Technical field】 [0001] The invention relates to a heating device, in particular to a rapid heating device. 【Background technique】 [0002] At present, the drip coffee pot uses a U-shaped aluminum heating tube with a built-in heating wire as a heater. Due to its structural limitation, it is difficult to make a specification with a rated power exceeding 1000W, so its low power leads to long heating time and small water output. , and the outlet water temperature is not uniform, the temperature of brewing coffee is not high; at the same time, because of the small contact surface between the heating part and the heat conduction part, the heat transfer efficiency is low, resulting in a large loss of heat energy generated by the heater, resulting in high energy consumption. The present invention promptly proposes in view of the insufficient research of prior art. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to provide a rapid h...
