Referring to FIG. 1 , one end of the water supply pipe of the inlet pump is connected to the output end of the feed water pump 10 , and the other end is connected to the heating tank 22 of the heat source device 20 to make the water pump 10 The input cold water can be sent to the heating tank 22 of the heat source device 2 via the water pipe 11; the water pipe u is provided with a solenoid valve 111, and the water tank 22 is provided with a water level sensor % for detecting Φ The water level in the hot tank 22 makes the solenoid valve 111 open when the water level is insufficient, so that the feed water pump 10 can input cold water into the heating tank 22. When the water level is sufficient, the solenoid valve 111 and the feed water pump 10 are operated. Disabled. A pressure controller 23 is connected to the heating tank 22 of the heat source device 20, so that the pressure controller 23 can detect the vapor pressure of the steam space in the upper portion of the water level of the heating tank 22 to control the starting or closing of the heater 21, wherein the vapor pressure is The lower limit value is generally set to 1.2 Bar; when the vapor pressure is lower than the pre-value, the pressure controller 23 will start the heater 21 to heat; when the _ vapor pressure reaches a predetermined value, the pressure control The heater 23 turns off the heater 21, stops heating, and maintains the temperature of the water in the heating tank 22 within a predetermined thermal temperature range. A safety valve 24 is disposed above the heating tank 22 for removing steam of excessive steam pressure in the heating tank 22. When the fault controller 23 fails to properly shut down the heater 2, the steam pressure inside the heating tank 22 is excessively high. The steam can open the outlet of the safety valve 24, and the steam is outputted by the outlet. The heating tank 22 is provided with an exhaust valve 25 for removing the upper portion of the heating tank 22 before being heated. Cold air, when the heating tank 22 is just beginning to add... [5] The opening of the exhaust valve 25 is not yet produced by the steaming valve. The opening of the exhaust valve 25 is in the open state 12 201102031, so that when the heating tank 22 starts heating, the air above the heating tank 22 can be expanded by heating. 25 discharge, when the water in the heating tank 22 is heated to generate steam and reach a suitable vapor pressure, the exhaust valve 25 is in a closed state; the bottom of the heating tank 22 is provided with a drain pipe 27, the drain pipe 27 is provided with a When the switch is used to drain the heating tank 22, the switch can be turned on to discharge the water in the heating tank 22 through the drain pipe 27. After the drain is completed, the switch is turned off to allow the heating tank 22 to refill the water. The cold water pipe assembly 40 is provided with a one-way pressure relief valve 42 and a flow meter 44, wherein the one-way pressure relief valve 42 prevents reverse flow of cold water, and the thermal expansion pressure in the first heat exchanger 31 and the second heat exchanger 32 is excessive. Part of the water is depressurized via the one-way relief valve 42; and the flow meter 44 meters the flow of water through the cold water pipe assembly 4 to control the inlet water pump 1 and the brewing solenoid valve 52 through the calculated water flow rate. Turning on or off 'to make the brewing number of each cup is precisely controlled. The brewing unit is disposed between the hot water pipe 51 and the temperature regulating unit 60, the brewing unit 50 has a brewing solenoid valve 52 and brewing The head 53, the hot water from the hot water pipe 51 and the cold water from the temperature regulating unit are mixed, and then can flow out through the brewing unit 50 to the filter bowl (not shown) connected under the brewing head 53 for extraction and preparation. The tempering unit can be at least one throttling element 601 having a flow path that can be adjusted to limit the flow of cold water to allow the inlet water pump to pass the cold water input through the cold water pipe assembly 40. Appropriate flow can enter the section via the outlet pipe 43 The heat exchanger 31 and the second heat exchanger 32 perform heat exchange 'heating into hot water' and then input to the brewing unit 50 by the hot water pipe 51; while the other part of the cold water is input through the cold water feeding pipe 61. Cooking the unit 5〇, adjusting the temperature of the water entering the brewing unit 5, so that the cold water enters the brewing unit 5〇 in an appropriate proportion, and is mixed with the hot water to form a water temperature suitable for brewing 13 201102031; The throttling element 601 can be a throttle joint or a throttle valve. Referring to FIG. 4, in another preferred embodiment of the present invention, the first hot water shunt tube 70 is provided with a throttle element 1〇〇. The throttle element 1 has a flow path for regulating the flow to limit the flow of hot water, while allowing hot water of an appropriate flow rate to enter the brewing unit 5G; the throttling device may be a throttle joint or a throttle valve. The hot water flow pipe 71 is provided with a flow element 丨〇1 having a flow path for adjusting the flow rate to limit the steam money, and allowing the steam flowing properly to enter the preheating return hole of the brewing unit 50. Medium, thereby controlling the brewing head 53 to preheat to an appropriate temperature; the throttle element 1〇1 may be a throttle joint or a throttle valve. Please refer to FIG. 5, in another preferred embodiment of the present invention, the temperature regulating unit 60 has two throttle elements, a temperature regulating tube 92A, and a The manifold 92B, the two solenoid valves 93A, 93B, the towel 'the temperature regulating tube 92A, the manifold 92B are connected in parallel with each other, and are disposed between the brewing unit 50 and the cold water feeding pipe 61; the two throttle elements 91A And 91B are respectively disposed on the temperature regulating pipe 92A and the manifold 92B for adjusting the liquid flow rate in the temperature regulating pipe 92A and the manifold 92B; and the two electromagnetic valves 93A and 93B are respectively disposed in the temperature regulating The tube 92A and the manifold 92B are disposed between the two throttle members 91A, 91B and the brewing single core; the throttle members 91A, 91B may be throttle joints or throttle valves. Therefore, in this embodiment, there are a total of two sets of throttling_A, and solenoid valves 93A, 93B.
