[0020] Figure 1 This is a diagram of the water circuit structure of the coffee machine according to this utility model; Detailed Implementation

[0021] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0024] See Figure 1 This utility model discloses a water circuit structure for a coffee machine, including a water tank, an ice water pipe assembly, and a hot water pipe assembly. The water tank has a first interface and a second interface. Specifically, the ice water pipe assembly includes an ice water tank, an ice cube holder, an ice-making module, a first pipe, and a second pipe. One end of the first pipe is connected to the first interface, and the other end of the first pipe is connected to the ice water tank. One end of the second pipe is connected to the ice water tank, and the other end of the second pipe is connected to the ice-making module. The ice-making module is connected to the ice cube holder. The ice cube holder has a return water pipe. The return water pipe is connected to the ice water tank, and the ice water tank is connected to an ice water outlet pipe.

[0025] In addition, the hot water pipe assembly includes a hot water component, a third pipe, and a fourth pipe. One end of the third pipe is connected to the second interface, and the other end of the third pipe is connected to the hot water component; one end of the fourth pipe is connected to the hot water component.

[0026] Based on the above structure, the water circuit structure is applied to a coffee machine. During use, room temperature water can be stored in the water tank of the coffee machine. The ice cube tray, ice water tank, and ice-making module are all installed on the coffee machine.

[0027] During the ice-making process, the electromagnetic pump of the coffee machine draws water from the storage tank through the first interface into the first pipe, then through the first pipe into the ice water tank, then through the ice water tank into the second pipe, and finally through the second pipe into the ice-making module. After being made into ice cubes by the ice-making module, the ice cubes are placed into the ice cube box, which can then store ice cubes.

[0028] When making coffee, the room temperature water in the water tank can flow through the second pipe to the third pipe under the action of the coffee machine's electromagnetic pump, and then flow through the third pipe to the hot water unit. After the hot water unit heats the water, it is then discharged through the fourth pipe for coffee brewing, or it can be drunk directly.

[0029] Of course, if you want iced coffee, you can take ice cubes out of the ice cube tray and put them into the brewed coffee. This way, you can make iced coffee directly without a separate ice maker. By arranging the water circuit structure described above in a single coffee machine, you can make iced coffee, saving resources and reducing space usage. In addition, after the ice cubes in the ice cube tray melt, the resulting ice water can also flow back to the ice water tank through the return pipe. The ice water can then be discharged through the ice water outlet pipe on the ice water tank, which can provide ice water directly or be used to brew coffee, making the machine multi-functional.

[0030] Furthermore, a first water level sensor and a second water level sensor can be installed inside the chilled water tank. Specifically, the first and second water level sensors are spaced apart along the height of the chilled water tank. The first water level sensor can be located at the top of the chilled water tank, and the second water level sensor can be located at the bottom of the chilled water tank. In this way, the first water level sensor can detect the highest water level in the chilled water tank, while the second water level sensor can detect the lowest water level in the chilled water tank. Specifically, a first valve body is installed on the aforementioned first pipe. The first valve body is used to receive the water level signal from either the first or second water level sensor.

[0031] When the second water level sensor in the chilled water tank detects that the water level is too low, the first valve body receives the low water level signal from the second water level sensor and opens. The electromagnetic pump inside the coffee machine then replenishes the chilled water tank with water from the storage tank. Since the chilled water tank also receives chilled water from the ice cube tray via the return pipe, this counteracts the ambient temperature water entering the chilled water tank, thus increasing the amount of chilled water. Conversely, when the first water level sensor detects that the water level in the chilled water tank is too high, the first valve body receives the high water level signal from the first water level sensor and closes, stopping the introduction of ambient temperature water. This allows for convenient control of the amount of chilled water stored.

[0032] Furthermore, the aforementioned third pipe is equipped with a second valve body, which has a first connector, a second connector, and a third connector. The first connector is connected to the second interface, and the second connector is connected to the chilled water tank through the fifth pipe. The third connector is connected to the first outlet pipe. In this way, room temperature water discharged from the second interface of the water tank can be discharged through the third pipe, and guided through the first connector to the third connector, and then guided through the third connector to the first outlet pipe, thus allowing room temperature water to be discharged through the first outlet pipe.

[0033] Of course, the first connector can also be closed, and the water in the ice water tank can be guided to the third connector through the second connector. In this way, the water discharged through the first outlet pipe is the cold water in the ice water tank.

[0034] Furthermore, a pressure relief pipe is connected to the first outlet pipe, and a first pressure relief valve is installed on the pressure relief pipe. The first pressure relief valve can perform a pressure relief action on the inside of the pipe when water is discharged from the first outlet pipe to prevent the internal pressure of the pipe from being too high.

[0035] Furthermore, the fourth pipe is equipped with a third valve body, which in turn has a fourth connector, a fifth connector, and a sixth connector. The fourth connector is connected to the hot water unit, the fifth connector is connected to a second outlet pipe, and the sixth connector is connected to a third outlet pipe. In this way, water heated by the hot water unit can be guided through the fourth pipe to the fourth connector, and then through the fourth connector to either the fifth or sixth connector.

[0036] When the fourth and fifth connectors are connected, the hot water produced by the hot water system can be guided through the fifth connector to the second outlet pipe, and then discharged to the hot water outlet for direct use as drinking water. When the fourth and sixth connectors are connected, the hot water produced by the hot water system can be guided through the sixth connector to the third outlet pipe to the coffee brewing outlet, and the discharged hot water can be used for coffee brewing. The appropriate outlet can be selected according to actual needs.

[0037] Furthermore, the first outlet pipe is equipped with a fourth valve body, which has a seventh connector, an eighth connector, and a ninth connector. The seventh connector is connected to the third pipe, the eighth connector is connected to the hot water component, and the ninth connector is connected to the fourth outlet pipe. The first outlet pipe can guide room temperature water directly discharged from the storage tank or cold water discharged from the ice water tank to the seventh connector, and then guide the water to the eighth or ninth connector.

[0038] That is, the room temperature water or cold water discharged from the first discharge pipe can be directly guided to the eighth connector through the seventh connector, heated by the hot water component, and then discharged; while the room temperature water or cold water discharged from the first discharge pipe can also be guided to the ninth connector through the seventh connector, and then guided to the fourth discharge pipe for cold water rinsing.

[0039] Of course, a second pressure relief valve can also be installed in the fourth outlet pipe to relieve pressure inside the pipe.

[0040] Furthermore, the water tank is equipped with a third interface, which is connected to a steam assembly, specifically a steam boiler and steam pipes. The steam boiler is connected to the third interface, and the steam pipes are connected to the steam boiler. Thus, when coffee milk foam needs to be made, the room temperature water in the water tank can be guided to the steam boiler through the third interface, heated in the steam boiler to generate steam, and then discharged through the steam pipes to make milk foam.

[0041] Of course, a third pressure relief valve can also be installed on the steam outlet pipe to relieve pressure on the steam outlet pipe.

[0042] Furthermore, a fifth valve body can be installed on the chilled water outlet pipe. This fifth valve body has a first, second, and third connecting port. The first connecting port connects to the chilled water tank, the second connecting port connects to the chilled water outlet pipe, and the third connecting port connects to the ice-making module. In this way, the chilled water in the chilled water tank can be guided through the first connecting port to either the second or third connecting port. Specifically, the chilled water in the chilled water tank can be guided through the first connecting port to the second connecting port, and then directly through the second connecting port to the chilled water outlet pipe for use. Alternatively, the chilled water can be guided through the first connecting port to the third connecting port, and then directly through the third connecting port to the ice-making module for ice production. Using the chilled water from the chilled water tank for ice production results in a lower water temperature and requires less energy.

[0043] It should be noted that the second, third, fourth, and fifth valve bodies mentioned above can all be implemented using the existing electromagnetic three-way valve structure.

[0044] This embodiment also provides a coffee machine, including the water circuit structure of the coffee machine described above.

[0045] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
