In a brewing system using a prior art brewing mechanism, when the flusher system is in a standby state, the system activates the heating device (1) 0) such that the water in the heating device (no) is heated while the heat exchanger (12G) is inside The water will be heated by heat exchange with the heating device (heating to the stable temperature - and the gas will be generated by the hot water pipe (16〇), and will be cooled and condensed into water, and the azole will be condensed into water. , av), flowing back from the mouth (150) through the three-way battalion (121) and flowing back into the heat exchanger (12) and preheating the brewing unit (17G) by means of a continuous platter When the team knows how to make a mouthful of coffee or tea, you can use a controlled control of the ancient and w-water to find the mouth of the drink. Tian, f cook 处于 is in the test drink σ ~ and brewing unit (1). two? Second = the system will start the pump to cook the solenoid valve (1 71) 'Cold water through the 6 M347905 pump (100) into the cold water pipe (i30) 'sequentially enter the cold water cannula (122), hot father exchange benefits (120) The inner 'cold water and the heat exchanger (12 〇) are mixed with the preheated water in the standby state. The hot water pipe (16 〇) and the three-way pipe (丨2 丨) and the return pipe (1 5 0) enter the brewing unit (丨7〇) and flow out from the filter bowl (丨72) to complete the extraction. Since various beverages such as coffee or tea each have a better extraction temperature, and in addition, the temperature of the water drawn by the pump (100) is different, so the purpose of the prior art is to achieve a temperature of _ to 5 weeks. The cooking mechanism achieves the effect of adjusting the temperature by guiding the cold water into the hot water pipe (160) through a temperature regulating pipe (18 〇) between the cold water pipe (130) and the hot water pipe (160). However, the prior art brewing mechanism has the following disadvantages: First, when the pump (1〇〇) and the brewing solenoid valve (171) of the brewing unit (170) are activated, the cold water is passed through the cold water cannula (122). It is flushed into the heat exchanger (120) and mixed with the preheated water in the heat exchanger (12〇). The mixed hot water will enter the brewing unit by the hot water pipe (160) and the return pipe (150). (17〇) re-mixing once, so the boiling water of the brewing solenoid valve (171) of the brewing unit (170) is the highest when the water is initially discharged, and it is necessary to repeat the continuous operation. The temperature of the hot parent (120) through the hot water pipe (16 〇) and the hot water in the return pipe (15 〇) tends to be stable. Secondly, if the prior art brewing mechanism is used to brew different volumes of beverages, the amount of water flowing into the heat exchanger (120) by the cold water pipe (130) per unit time varies depending on the amount of water required. And the temperature of the water mixed with the preheated water in the heat exchanger (120) and entering the brewing unit (170) through the hot water pipe (170) will also be different, thus causing the brewing unit (1 state M347905 cup (172) temperature for extraction i. Further, the hot water flowing into the brewing unit (170) can be adjusted by the temperature regulating tube (180), but it flows into the brewing unit (17〇). The water, including the water from the hot water pipe (160) and the return pipe (18 〇), is also unstable, so the prior art brewing mechanism has a lack of stable temperature adjustment. Large-capacity drinks may cause temperature degradation during continuous brewing due to insufficient heat exchange area of the heat exchanger (1). [New content] ~ = The above-mentioned creation still exists for the prior art brewing mechanism. Right dry defects or inconvenience, and then set ^ M .. t out a brewing mechanism having a constant temperature effect, and the brewing mechanism has a brewing mechanism that continuously operates to perform heat exchange or hot and cold water, and has a temperature of conversion, that is, a temperature The novel function of temperature is the function of temperature.
