Waterway mechanism of coffee pot for outputting steam

Abstract

The invention discloses a waterway mechanism of steam coffee pot, in particular to a domestic electric heater to dissolve coffee to solve the problem of difficult control of water temperature, which is characterized by the following: the water pump inlet connects a tank and the water pump outlet connects water inlet of electrothermal disc; the water outlet of electrothermal disc connects inlet ofthree-way device; the one-way valve is set at the first outlet of the three-way device; the second outlet of the three-way device interconnects the inlet of the three-way magnetic valve; the first outlet of the three-way magnetic valve interconnects the inlet of two-way switching valve; the outlet of the two-way switching valve interconnects the steam bar; the second output of the three-way magnetic valve connects the inlet of the buffer groove; the hot water flows to dissolve coffee when opening the one-way valve of the three-way device with steam provided by steam bar.

Description

technical field [0001] The present invention relates to a household electric water heater, in particular to a household electric water heater capable of brewing coffee. Background technique [0002] The waterway mechanism in the espresso makers currently on the market, such as figure 1 shown. The water inlet 11 of the water pump 1 is connected to a water tank, the water outlet 12 of the water pump 1 is connected to the water inlet 21 of the electric heating plate 2 through the water pipe 101; the water outlet 22 of the electric heating plate 2 is connected to the inlet 31 of the three-way reversing valve 3 through the pipeline 102; The first outlet 32 ​​of the reversing valve 3 is connected to the steam rod 4 through the pipeline 103; the second outlet 33 of the three-way reversing valve 3 is connected to the inlet 51 of the three-way solenoid valve 5 through the pipeline 104; The outlet 52 is connected to the inlet 61 of the drip tray 6 through the pipeline 105 ; the seco...

AI Technical Summary

Problems solved by technology

Since the heating plate 2 will go through the pipeline 102, the three-way reversing valve 3, the pipeline 104, the three-way electromagnetic valve 5 and the pipeline 105 from the electric heating plate 2 to the drip pan 6, the water temperature in the whole path will obviously decrease, and the actual water temperature flowing out from the drip pan 6 is very high. Difficult to control and debug: If the specified value is set high, the temperature inside the coffee pot with steam function will rise, which will affect the safety performance of the whole machine; Will directly affect the taste of the coffee liquid
