DETAILED DESCRIPTION

[0030] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0031] In the description of this utility model, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0033] The following is a further description of the embodiments of the present invention with reference to the accompanying drawings.

[0034] According to some embodiments of the present invention, referring to Figures 1 to 3 The coffee machine water control system includes a water supply component 100, a low-temperature heater 110, a steam heater 130, an extraction device 140, a first valve 151, a second valve 152, a third valve 153, and an air outlet pipe 160. The water inlet of the low-temperature heater 110 is connected to the water outlet of the water supply component 100, and the water outlets of the low-temperature heater 110 are respectively connected to the first pipe 121 and the second pipe 122. The steam heater 130 is connected to the water outlet of the first pipe 121. The extraction device 140 is connected to the water outlet of the second pipe 122. The first valve 151 is provided on the first pipe 121. The second valve 152 is provided on the second pipe 122. The third valve 153 is connected to the air outlet of the steam heater 130. The air outlet pipe 160 is connected to the air outlet of the third valve 153.

[0035] Reference Figure 3 When steam is needed, the first valve 151 and the third valve 153 are opened, and the second valve 152 is closed. The water in the water supply component 100 enters the low-temperature heater 110 for heating. The water heated by the low-temperature heater 110 enters the first pipe 121 and then enters the steam heater 130 for further heating to form steam. Finally, it passes through the third valve 153 and enters the air outlet pipe 160. The steam is discharged from the air outlet pipe 160 into the milk cup to foam the milk. When steam production is completed, the first valve 151 and the third valve 153 are closed, and the steam stops being ejected outward. When making steam, since the water in the first pipe 121 has been preheated, the time it takes to make steam is greatly reduced. In addition, when switching from making steam to making coffee, there is no need to wait for the water to cool down.

[0036] Reference Figure 2When coffee is ready, first valve 151 and third valve 153 are closed, and second valve 152 is opened. Water heated by low-temperature heater 110 enters second pipe 122 and then extraction device 140, where it blends with coffee powder in extraction device 140 to form coffee liquid. Once coffee is ready, second valve 152 is closed.

[0037] The water circuit control system of the coffee machine can improve the efficiency of making steam and coffee, has low cost, can quickly switch between steam and coffee, has good milk foaming effect, and has a long equipment life.

[0038] Preferably, refer to Figure 1 The water supply component 100 includes a water tank 101 and a water pump 102 . The water outlet of the water tank 101 is connected to the water inlet of the water pump 102 , and the water outlet of the water pump 102 is connected to the low-temperature heater 110 .

[0039] According to some embodiments of the present invention, referring to Figures 1 to 3 The coffee machine water control system also includes a waste water box 170. The first valve 151 is a three-way solenoid valve. The first valve 151 is connected to the waste water box 170. The first valve 151 can connect the steam heater 130 to the waste water box 170, or connect the steam heater 130 to the low-temperature heater 110.

[0040] It is understandable that when the steam production is completed, the third valve 153 is closed, the steam stops being ejected outward, the first valve 151 disconnects the steam heater 130 from the low-temperature heater 110, and connects the steam heater 130 to the waste water box 170, so that the pressurized water and steam in the steam heater 130 enter the waste water box 170 through the first valve 151, avoiding sudden jetting when the third valve 153 is opened again, which may cause safety problems.

[0041] It should also be understood that the water used to make steam is heated in the low-temperature heater 110 before being heated a second time in the steam heater, resulting in high heating efficiency, low costs, and effective steam drying. When steam production is complete, the third valve 153 closes, immediately cutting off the flow of water from the steam heater 130 to the milk liquid. This prevents residual gas in the steam heater 130 from slowly entering the milk, preventing the milk from forming large bubbles. This improves milk foaming and avoids foaming failures. Furthermore, when steam production is complete, the first valve 151 disconnects the steam heater 130 from the low-temperature heater 110 and connects the steam heater 130 to the wastewater box 170. This allows any remaining steam in the steam heater 130 to flow through the first valve 151 into the wastewater box 170, preventing the steam heater 130 from maintaining a high temperature and high pressure state, thereby increasing its service life.

[0042] According to some embodiments of the present invention, referring to Figure 2 The coffee machine water control system also includes a waste water box 170. The second valve 152 is a three-way solenoid valve. The second valve 152 is connected to the waste water box 170. The second valve 152 can connect the extraction device 140 to the waste water box 170, or connect the extraction device 140 to the low-temperature heater 110.

[0043] It is understandable that when coffee is made, the second valve 152 disconnects the extraction device 140 from the low-temperature heater 110 and connects the extraction device 140 to the waste water box 170, allowing excess water in the extraction device 140 to flow into the waste water box 170 through the second valve 152.

[0044] It should be noted that the waste water box 170 can be connected to the first valve 151 and the second valve 152 at the same time. At this time, the first valve 151 and the second valve 152 are both three-way solenoid valves.

[0045] According to some embodiments of the present invention, the third valve 153 is a two-way solenoid valve. The third valve 153 opens and closes quickly and operates stably, thereby preventing continuous ejection of steam.

[0046] According to some embodiments of the present invention, referring to Figure 1 The coffee machine water system control system also includes a control board 180, which is electrically connected to the first valve 151, the second valve 152, and the third valve 153. The control board 180 is also electrically connected to the water supply component 100, the low-temperature heater 110, the steam heater 130, and the extraction device 140. The control board 180 intelligently controls various electronic components, facilitating user operation.

[0047] According to some embodiments of the present invention, the third valve 153 is a one-way valve. The steam from the steam heater 130 can push open the top ball in the third valve 153 and enter the exhaust pipe 160. When the steam production stops, the steam pressure is not enough to push open the top ball of the third valve 153, thereby disconnecting the third valve 153.

[0048] According to some embodiments of the present invention, referring to Figure 1 The coffee machine water control system further includes a liquid outlet pipe 190 , which is connected to the liquid outlet end of the extraction device 140 .

[0049] Throughout this specification, references to the term "some embodiments" indicate that a specific feature, structure, material, or characteristic described in conjunction with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, schematic representations of these terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0050] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
