Drip type coffee machine

Abstract

The invention provides a drip type coffee machine which comprises a water tank, a heating pipe assembly and a brewing funnel; the water tank is connected with the first end of a heating pipe of the heating pipe assembly through a first pipeline; the brewing funnel is connected with the second end of the heating pipe of the heating pipe assembly through a second pipeline, so that water in the water tank flows into the brewing funnel; and a narrow flow area of which the cross-sectional area of at least part of the inner diameter is smaller than that of the internal diameter, close to the lower section of the heating tube, of the first pipeline is arranged at the upper section, close to the water tank, of the first pipeline. The drip type coffee machine further comprises at least one water outlet pipe, a water outlet is formed in the water tank, one end of the water outlet pipe is connected with the water outlet, and a control switch is arranged on the water outlet; and the other end of the water outlet pipe is communicated with the lower section of the first pipeline. Through the drip type coffee machine provided by the invention, the problems of high pre-stage water level, high pressure, high flow rate, low temperature, low post-storage water level, medium pressure, low flow rate and high temperature in the water boiling process are effectively solved; and furthermore, the drip type coffee machine provided by the invention is simple and practical in structure.

Description

technical field [0001] The invention belongs to the field of small household appliances, in particular to a drip coffee machine. Background technique [0002] At present, most of the drip coffee pots widely used in the market are heated by horseshoe-shaped tubes, and there is only one pipe from the water outlet of the water tank to the water inlet of the heating pipe. The water level is high, the pressure is high, and the flow rate is high in the early stage of the boiling process, resulting in low outlet water temperature. In the later stage, the water level is low, the pressure is medium, and the flow rate is slow, resulting in high outlet water temperature and ultimately low coffee temperature. [0003] Similarly, in the published patent literature, such as the Chinese patent with the authorized announcement number CN201861447U, the technical solution proposed is that there is a container at the bottom of the water tank, and there is a floating valve in the container, and...

AI Technical Summary

Problems solved by technology

[0002] At present, most of the drip coffee pots widely used in the market are heated by horseshoe-shaped tubes, and there is only one pipe from the water outlet of the water tank to the water inlet of the heating pipe. The water level is high, the pressure is high, and the flow rate is high before the boiling process, resulting in low outlet water temperature. In the later stage, the water level is low, the pressure is medium, and the flow rate is slow, resulting in high outlet water temperature and finally low coffee temperature.

[0003] Similarly, in the published patent documents, such as the Chinese patent with the authorized announcement number CN201861447U, the technical solution proposed is that there is a container at the bottom of the water tank, and there is a floating valve in the container, and the floating valve is used to control the flow of water so that the water flows evenly into the heating pipe. So that there is still water that starts to enter the heating pipe and the temperature after being heated cannot be higher than the temperature of the water that enters the heating pipe after being heated
