When the steam switch 243 is turned on, the circuit loop where the second heating assembly 252 is located is switched on, the second heating assembly 251 is in an energized heating state, at this time, the circuit loop where the first heating assembly 251 is located is also in a switched on state, the first heating assembly 251 is in an energized heating state, and the heating members are in a two-stage heating mode; when the steam switch 243 is turned off, the circuit loop in which the second heating assembly 252 is located is cut off, the second heating assembly 252 is in the power-off state, the circuit loop in which the first heating assembly 251 is located is not affected at this time, and is still in the on state, the first heating assembly 251 is in the power-on heating state, and the heating member is in the primary heating mode. As an alternative, the steam outlet of the steam conduit 240 may also be provided at other locations of the coffee maker, for example on an outer wall of the water tank 210 or an outer wall of the brewing chamber 220. In particular, the steam outlet is preferably disposed at a position lower than the steam inlet 241, so that when the water temperature in the water tank 210 is sufficiently high, sufficient steam is generated to enter the steam switch 243 through the steam pipe 240, and the steam switch 243 is operated by the sufficient steam.
Alternatively, the temperature/pressure control part includes a solenoid valve 242 and a temperature sensor and/or a pressure sensor, and the temperature sensor and/or the pressure sensor controls the solenoid valve 242 to be closed to disconnect the steam pipe 240 when the detected temperature and/or pressure reaches a predetermined value.
Referring to fig. 6 to 7, when the coffee maker is used, the top cover 100 is opened to drive the ball check valve 213 to leave the filler 212, and a proper amount of water is injected into the filler 212, and enters the water tank 210 along the dotted line in fig. 6, wherein the water is injected in an amount such that the water level is below the steam inlet 241 to prevent the water from entering the steam pipe 240. The top cover 100 is closed, and the safety ball valve 213 falls on the filling port 212 to seal the filling port 212.
The power switch 260 is turned on, the heating part 250 heats the water tank 210 in the primary heating mode, the steam switch 243 is turned on, and the steam switch 243 controls the solenoid valve 242 to be turned on and controls the heating part 250 to heat the water tank 210 in the secondary heating mode, so that the water in the water tank 210 is heated more rapidly. The water in the water tank 210 is heated by the heating part 250 in the two-stage heating mode to generate steam, and the steam enters the steam inlet 241 and enters the steam switch 243 through the steam pipe 240. When the water is heated to a sufficient temperature, a sufficient amount of steam is correspondingly generated to pass through the steam switch 243, the steam switch 243 performs a turning action under the action of the sufficient amount of steam, the solenoid valve 242 is controlled to be closed while the steam switch 243 is closed, the steam pipeline 240 is disconnected, and at this time, a closed space is formed in the water tank 210. At the same time, the steam switch 243 switches the heating element 250 from the two-stage heating mode to the one-stage heating mode, i.e. the heating element 250 continues to heat the water in the water tank 210 under low power conditions, so that steam is continuously generated from the water in the water tank 210, a certain steam pressure is generated at the upper part of the water tank 210, under the action of the steam pressure, hot water in the water tank 210 enters the brewing chamber 220 along the dotted line shown in fig. 7 to brew coffee and flows into the coffee pot 300, i.e. the hot water enters the hot water pipe 230 through the water inlet 231 in the recess 211 and is sprayed in the brewing chamber 220 through the shower head 233 arranged at the water outlet 232, the hot water thoroughly soaks and extracts coffee powder in the brewing chamber 220 to brew coffee, and the brewed coffee flows into the coffee pot 300 placed on the placement platform through the outlet of the brewing chamber 220.
Since the steam switch 243 is turned off when a sufficient amount of steam is generated in the water tank 210, the steam pipe 240 is cut off, and then the hot water is pressed into the brewing chamber 220, the water in the water tank 210 is boiled, which is warmer and more uniform than the hot water prepared by the conventional drip coffee maker 300.
When the steam pressure in the water tank 210 is too high due to the excessive steam generated in the water tank 210, the safety ball valve 213 is lifted up by the steam pressure, and the excessive steam is discharged out of the water tank 210 along the dotted line shown in fig. 6, so that the steam pressure in the water tank 210 is maintained within a proper range.
The power switch 260 is turned off, the heating part 250 stops heating, the steam switch 243 is turned on, and the control solenoid valve 242 is turned on at the same time to prepare for the next use.
