Description

Technical Field

[0001] This utility model belongs to the field of drinking water equipment, specifically relating to a tea bar machine. Background Technology

[0002] With the improvement of living standards, tea bar machines have begun to enter thousands of households in recent years. Their design, with a water tank at the bottom and a kettle at the top, has replaced the traditional water dispenser. The water in the water tank at the bottom flows through the water circuit component into the kettle at the top for heating or for drinking directly from the kettle at room temperature, making it more convenient for consumers.

[0003] Most tea bar machines use bottled water. However, due to the varying quality of bottled water, bacteria can easily grow in the internal pipes of the water system when the bottled water is of poor quality or when the tea bar machine is not used for a long time. Existing tea bar machines cannot sterilize and clean the entire water system, thus failing to guarantee the safety of users' drinking water. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a tea bar machine to solve the problem of bacteria growing due to the inability to sterilize and clean the water circuit components.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A tea bar machine, comprising a water storage container and a water circuit assembly, wherein the water circuit assembly is provided with a first water outlet connector and a second water outlet connector, the water circuit assembly comprising: a hot water outlet pipe connected between the water storage container and the first water outlet connector for supplying water to the first water outlet connector, wherein the hot water outlet pipe is provided with a hot water pump connected to the water storage container, a hot water switching valve connected to the first water outlet connector, and a heating element connected between the hot water pump and the hot water switching valve; and a normal temperature water outlet pipe connected between the water storage container and the second water outlet connector for supplying water to the second water outlet connector, wherein the normal temperature water outlet pipe is provided with a normal temperature water pump connected to the water storage container and a heating element connected between the hot water pump and the hot water switching valve; and a normal temperature water outlet pipe connected between the water storage container and the second water outlet connector for supplying water to the second water outlet connector, wherein the normal temperature water outlet pipe is provided with a normal temperature water pump connected to the water storage container and a heating element connected between the hot water pump and the second water outlet connector. The system includes a normal temperature switching valve connected to a connector; a first cleaning pipeline equipped with a first solenoid valve for controlling the opening and closing of the first cleaning pipeline and a first check valve connected downstream of the first solenoid valve; the inlet of the first cleaning pipeline is connected to the normal temperature outlet pipeline between the normal temperature water pump and the normal temperature switching valve, and the outlet of the first cleaning pipeline is connected to the hot water outlet pipeline between the hot water pump and the heating element; a second cleaning pipeline connected between the hot water switching valve and the normal temperature switching valve; when the tea bar machine is in self-cleaning mode, the water flow in the hot water outlet pipeline flows into the normal temperature outlet pipeline through the second cleaning pipeline, and finally returns to the hot water outlet pipeline through the first cleaning pipeline, thereby circulating and cleaning the water system components. This technical solution has the following technical effects:

[0006] This invention connects a hot water outlet pipe and a normal temperature water outlet pipe via a first and a second cleaning pipe. A heating element is installed on the hot water outlet pipe. When the user selects to use hot water, the water in the storage container is preheated at the heating element as it passes through the hot water outlet pipe, and then flows through the first outlet connector into the kettle placed on top of the tea bar machine for further heating. This improves the kettle's heating efficiency and shortens the time required for the kettle to heat the water to the set temperature, thus reducing the user's waiting time and enhancing the user experience. When not using water, the user can select the self-cleaning mode. In this mode, the water circuit assembly is sterilized by switching between hot and normal temperature valves and opening the first solenoid valve. The heating element heats the flowing water to generate high-temperature water, which circulates within the sterilization water circuit and is eventually discharged, achieving sterilization and cleaning of the water circuit assembly. Users can periodically select the self-cleaning mode to sterilize and clean the water circuit assembly, effectively preventing bacterial growth inside the tea bar machine's water circuit assembly and ensuring safer drinking water. Meanwhile, because hot water pumps and ambient temperature pumps are installed on the hot water outlet pipe and the ambient temperature outlet pipe respectively to control the water circuit, the water intake process of the hot water outlet pipe and the ambient temperature outlet pipe is relatively independent. There is no need to use a water circuit switching valve to switch between the hot water outlet pipe and the ambient temperature outlet pipe, which reduces the use of water circuit switching valves, reduces the complexity of the control process and the overall production cost of water circuit components.

[0007] In the aforementioned tea bar machine, a second one-way valve is also installed on the hot water outlet pipe, connecting the heating element and the hot water pump. When the user selects the self-cleaning mode of the tea bar machine, the second one-way valve prevents the high-temperature water in the heating element from flowing back to the hot water pump after the pump stops working, thus avoiding impact or damage to the pump from the high-temperature water flow, and also preventing some high-temperature water from leaking into the water storage container through the pump.

[0008] In the aforementioned tea bar machine, a third check valve is also installed on the ambient temperature water outlet pipe, connecting the ambient temperature water pump and the ambient temperature switching valve. The inlet end of the first cleaning pipe is connected between the outlet of the third check valve and the ambient temperature switching valve. When the user selects the self-cleaning mode of the tea bar machine, the third check valve prevents the high-temperature water flowing out of the ambient temperature switching valve from flowing back to the ambient temperature water pump, avoiding impact or damage to the ambient temperature water pump from the high-temperature water flow, and also preventing some high-temperature water from leaking into the water storage container through the ambient temperature water pump.

[0009] In the aforementioned tea bar machine, a cleaning water pump is installed on the second cleaning pipeline. When the tea bar machine is in self-cleaning mode, the second cleaning pipeline uses the cleaning water pump to draw water from the hot water outlet pipeline to the room temperature water outlet pipeline. In self-cleaning mode, the cleaning water pump assists in the rapid circulation of water within the water system components for sterilization and cleaning.

[0010] In the aforementioned tea bar machine, the water system component also includes a drain pipe. The inlet end of the drain pipe is connected to a second cleaning pipe between the cleaning water pump and the ambient temperature switching valve, so as to discharge the wastewater from cleaning the water system component through the drain pipe. By setting up the drain pipe, all the wastewater in the water system component can be discharged by simply switching the ambient temperature switching valve, avoiding the retention of wastewater in the water system component.

[0011] In the aforementioned tea bar machine, a solenoid valve and a water collection box for collecting wastewater are installed on the drain pipe. The solenoid valve is located upstream of the water collection box to open and close the drain pipe. When high-temperature water circulates and sterilizes the water system components, the second solenoid valve cuts off the drain pipe to prevent water from flowing out. When it is necessary to discharge the wastewater after cleaning the water system components, the second solenoid valve is opened so that it no longer cuts off the drain pipe, and all the wastewater flows into the water collection box for centralized collection.

[0012] In the aforementioned tea bar machine, an ice tank is also installed on the ambient temperature water outlet pipe. The ambient temperature water outlet pipe cools the water flowing to the second water outlet connector through the ice tank. When the ice tank is not working, the water flowing out of the second water outlet connector is ambient temperature water; when the ice tank is working, the water flowing out of the second water outlet connector is cold water (i.e., water with a temperature lower than ambient temperature). Users can choose to use cold water or ambient temperature water according to their different needs, enriching the water output of the second connector and improving the user experience.

[0013] In the aforementioned tea bar machine, the ice tank is connected between the water inlet of the first cleaning pipeline and the ambient temperature switching valve. Because solenoid valves are typically designed for ambient temperatures, they are prone to failure when the operating temperature is too low. Therefore, connecting the ice tank between the water inlet of the first cleaning pipeline and the ambient temperature switching valve prevents cold water from the ice tank from entering the first cleaning pipeline, thus preventing damage to the first solenoid valve from excessively cold water and ensuring its stable operation.

[0014] In the aforementioned tea bar machine, the water system assembly further includes a third cleaning pipe. The third cleaning pipe has a first cleaning switching valve and a second cleaning switching valve at its two ends. The first cleaning switching valve connects the inlet of the first cleaning pipe to the ambient temperature inlet of the ice tank, and the second cleaning switching valve connects the cold water outlet of the ice tank to the ambient temperature switching valve. When the user selects the self-cleaning mode of the tea bar machine, the high-temperature water flow from the ambient temperature switching valve flows through the third cleaning pipe to the first cleaning pipe. That is, the high-temperature water flow can bypass the ice tank through the third cleaning pipe, thus preventing wastewater used for cleaning the water system assembly from flowing into the ice tank and causing difficulty in drainage or damage to the ice tank.

[0015] In one type of tea bar machine described above, the heating element is a hot water tank; or, the heating element is an instant heating element. Using a hot water tank as the heating element allows the hot water pump to stop operating once all the cleaning water is centrally heated in the tank during the cleaning mode. This prevents the high-temperature water from the first cleaning pipe from mixing with the room-temperature water pumped by the hot water pump when it flows back to the heating element, thus avoiding a rapid drop in temperature and ensuring the sterilization effect of the high-temperature water. Simultaneously, it eliminates the need for continuous heating by the heating element, reducing its power consumption. Using an instant heating element significantly reduces the space occupied by the heating element in the tea bar machine, thereby preventing the machine from becoming too bulky.

[0016] The features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0029] This utility model discloses a tea bar machine, comprising a water storage container and a water circuit assembly. The water circuit assembly is provided with a first water outlet connector and a second water outlet connector. The water circuit assembly includes: a hot water outlet pipe connected between the water storage container and the first water outlet connector for supplying water to the first water outlet connector, which is provided with a hot water pump connected to the water storage container, a hot water switching valve connected to the first water outlet connector, and a heating element connected between the hot water pump and the hot water switching valve; and a room temperature water outlet pipe connected between the water storage container and the second water outlet connector for supplying water to the second water outlet connector, which is provided with a room temperature water pump connected to the water storage container and a room temperature water switching valve connected to the second water outlet connector. The system includes a valve replacement system; a first cleaning pipeline, which is equipped with a first solenoid valve for controlling the opening and closing of the first cleaning pipeline and a first check valve connected downstream of the first solenoid valve. The inlet end of the first cleaning pipeline is connected to the ambient temperature outlet pipeline between the ambient temperature water pump and the ambient temperature switching valve, and the outlet end of the first cleaning pipeline is connected to the hot water outlet pipeline between the hot water pump and the heating element; a second cleaning pipeline is connected between the hot water switching valve and the ambient temperature switching valve; when the tea bar machine is in self-cleaning mode, the water in the hot water outlet pipeline flows into the ambient temperature outlet pipeline through the second cleaning pipeline, and finally flows back to the hot water outlet pipeline through the first cleaning pipeline to circulate and clean the water circuit components. This invention connects a hot water outlet pipe and a normal temperature water outlet pipe via a first and a second cleaning pipe. A heating element is installed on the hot water outlet pipe. When the user selects to use hot water, the water in the storage container is preheated at the heating element as it passes through the hot water outlet pipe, and then flows through the first outlet connector into the kettle placed on top of the tea bar machine for further heating. This improves the kettle's heating efficiency and shortens the time required for the kettle to heat the water to the set temperature, thus reducing the user's waiting time and enhancing the user experience. When not using water, the user can select the self-cleaning mode. In this mode, the water circuit assembly is sterilized by switching between hot and normal temperature valves and opening the first solenoid valve. The heating element heats the flowing water to generate high-temperature water, which circulates within the sterilization water circuit and is eventually discharged, achieving sterilization and cleaning of the water circuit assembly. Users can periodically select the self-cleaning mode to sterilize and clean the water circuit assembly, effectively preventing bacterial growth inside the tea bar machine's water circuit assembly and ensuring safer drinking water. Meanwhile, because hot water pumps and ambient temperature pumps are installed on the hot water outlet pipe and the ambient temperature outlet pipe respectively to control the water circuit, the water intake process of the hot water outlet pipe and the ambient temperature outlet pipe is relatively independent. There is no need to use a water circuit switching valve to switch between the hot water outlet pipe and the ambient temperature outlet pipe, which reduces the use of water circuit switching valves, reduces the complexity of the control process and the production cost of water circuit components.

[0035] Example 1:

[0036] A tea bar machine, such as Figures 1 to 2 As shown, the system includes a cabinet 810, a back panel 820 mounted on the top of the cabinet 810, a water storage container 840, and a water circuit assembly. The water storage container 840, used to hold drinking water, is located inside the receiving cavity 811 of the cabinet 810. A kettle 830 and a room temperature kettle are placed on the cabinet 810. The water circuit assembly is used to transfer water from the water storage container 840 to the kettle 830 and the room temperature kettle. The water circuit assembly is provided with two water outlet connectors, which are located on the top of the cabinet 810 or on the back panel 820. These are a first water outlet connector 110 that supplies water to the kettle 830 and a second water outlet connector 120 that supplies water to the room temperature kettle. The water circuit assembly includes a hot water outlet pipe 200, a room temperature water outlet pipe 300, a first cleaning pipe 400, and a second cleaning pipe 500.

[0037] Hot water outlet pipe 200 is connected between water storage container 840 and first outlet connector 110 for supplying water to first outlet connector 110. Hot water outlet pipe 200 is equipped with a connected hot water pump 210, hot water switching valve 220 and heating element 230. Hot water pump 210 is connected to water storage container 840, hot water switching valve 220 is connected to first outlet connector 110, and heating element 230 is connected between hot water pump 210 and hot water switching valve 220. A normal temperature water outlet pipe 300 is connected between a water storage container 840 and a second water outlet connector 120 for supplying water to the second water outlet connector 120. The normal temperature water outlet pipe 300 is equipped with a connected normal temperature water pump 310 and a normal temperature switching valve 320. The normal temperature water pump 310 is connected to the water storage container 840, and the normal temperature switching valve 320 is connected to the second water outlet connector 120. A first cleaning pipe 400 is equipped with a connected first solenoid valve 410 and a first check valve 420. The first solenoid valve 410 is used for… The first cleaning pipeline 400 is controlled to open and close. The first one-way valve 420 is located downstream of the first solenoid valve 410. The inlet of the first cleaning pipeline 400 is connected to the ambient temperature outlet pipeline 300 between the ambient temperature water pump 310 and the ambient temperature switching valve 320. The outlet of the first cleaning pipeline 400 is connected to the hot water outlet pipeline 200 between the hot water pump 210 and the heating element 230. The second cleaning pipeline 500 is connected between the hot water switching valve 220 and the ambient temperature switching valve 320.

[0038] When the user selects the mode for obtaining hot water from the tea bar machine, the hot water switching valve 220 switches to the position connecting the hot water pump 210 and the first water outlet connector 110. The hot water pump 210 operates, and the water pumped by the hot water pump 210 flows into the heating element 230 for preheating. Because of the setting of the first one-way valve 420, the water flow in the first cleaning pipe 400 cannot flow from the first one-way valve 420 to the first solenoid valve 410. Therefore, the water flowing out of the heating element 230 can only flow to the hot water switching valve 220, and then flow to the first water outlet connector 110, so that the water flow can be introduced into the kettle 830 placed on the top of the cabinet 810 for heating.

[0039] When the user selects the mode for using room temperature water from the tea bar machine, the first solenoid valve 410 is closed to cut off the first cleaning pipe 400. The room temperature switching valve 320 switches to the position connecting the room temperature water pump 310 and the second water outlet connector 120. The room temperature water pump 310 operates. Because the closed first solenoid valve 410 can prevent the water in the room temperature water outlet pipe 300 from flowing through the first cleaning pipe 400, the water in the water storage container 840 drawn by the room temperature water pump 310 will only flow through the room temperature switching valve 320 of the room temperature water outlet pipe 300 to the second water outlet connector 120, so that the water can be introduced into the room temperature kettle placed on the top of the cabinet 810 for the user to use.

[0040] When the user selects the self-cleaning mode of the tea bar machine, the hot water switching valve 220 switches to the position connecting the hot water pump 210 and the second cleaning pipe 500, the ambient temperature switching valve 320 switches to the position connecting the second cleaning pipe 500 and the ambient temperature outlet pipe 300, the first solenoid valve 410 opens, the ambient temperature water pump 310 does not work, and the hot water pump 210 works. Figure 2 As shown by the arrow, the water pumped by the hot water pump 210 flows into the water storage container 840 and into the heating element 230, where it is heated to a high temperature. Then, it flows through the hot water switching valve 220 to the second cleaning pipe 500, and then through the normal temperature switching valve 320 into the first cleaning pipe 400, before flowing back into the heating element 230. In other words, the high-temperature water flows sequentially through the hot water outlet pipe 200, the second cleaning pipe 500, the normal temperature outlet pipe 300, and the first cleaning pipe 400 to achieve high-temperature water circulation for sterilization and cleaning within the water system components. At this point, stopping the hot water pump 210 will stop the supply of water to the hot water outlet pipe 200. During the circulation cleaning process, the heating element 230 can provide continuous heating or short-term heating to maintain the high-temperature water at the set temperature. After cleaning, the tea bar machine can operate in hot water mode or room temperature water mode to drain the wastewater in the water circuit components. Alternatively, the wastewater drain on the water circuit components can be opened to drain the wastewater in the water circuit components.

[0041] This utility model connects the hot water outlet pipe 200 and the normal temperature water outlet pipe 300 through the first cleaning pipe 400 and the second cleaning pipe 500. A heating element 230 is installed on the hot water outlet pipe 200. When the user selects to use hot water, the water in the water storage container 840 is preheated at the heating element 230 when it passes through the hot water outlet pipe 200. Then, it flows into the kettle 830 placed on top of the tea bar machine through the first water outlet connector 110 for heating. This improves the heating efficiency of the kettle 830 and shortens the time required for the kettle 830 to heat the water to the set temperature. In other words, it shortens the user's waiting time and improves the user experience. When not using water, users can select the self-cleaning mode. In this mode, the water circuit assembly can form a circulating sterilization water circuit by switching between the hot water switching valve 220 and the normal temperature switching valve 320 and opening the first solenoid valve 410. The heating element 230 can heat the flowing water to generate high-temperature water. The high-temperature water circulates in the sterilization water circuit and is eventually discharged to achieve sterilization and cleaning of the water circuit assembly. Users can regularly select the self-cleaning mode to sterilize and clean the water circuit assembly, effectively preventing bacteria from growing in the water circuit assembly inside the tea bar machine, making drinking water safer. Meanwhile, because hot water pump 210 and normal temperature water pump 310 are respectively installed on the hot water outlet pipe 200 and the normal temperature water outlet pipe 300 to control the water circuit, the water intake process of the hot water outlet pipe 200 and the normal temperature water outlet pipe 300 is relatively independent. There is no need to use a water circuit switching valve to switch between the hot water outlet pipe 200 and the normal temperature water outlet pipe 300, which reduces the use of water circuit switching valves, reduces the complexity of the control process and the overall production cost of water circuit components.

[0042] In this embodiment, a second one-way valve 240 is also provided on the hot water outlet pipe 200. The second one-way valve 240 is connected between the heating element 230 and the hot water pump 210 so that the water flow can only flow unidirectionally from the hot water pump 210 to the heating element 230. The outlet end of the first cleaning pipe 400 is connected to the hot water outlet pipe 200 between the outlet of the second one-way valve 240 and the heating element 230. When the user selects the self-cleaning mode of the tea bar machine, the setting of the second one-way valve 240 can prevent the high-temperature water flow in the heating element 230 and the high-temperature water flow that flows back from the first cleaning pipe 400 to the hot water outlet pipe 200 from flowing back to the hot water pump 210 after the hot water pump 210 stops working. This avoids the high-temperature water flow from impacting or damaging the hot water pump 210, and also prevents some of the high-temperature water flow from leaking into the water storage container 840 through the hot water pump 210.

[0043] A third check valve 330 is also provided on the ambient temperature water outlet pipe 300. The third check valve 330 is connected between the ambient temperature water pump 310 and the ambient temperature switching valve 320. The water inlet of the first cleaning pipe 400 is connected between the water outlet of the third check valve 330 and the ambient temperature switching valve 320. When the user selects the self-cleaning mode of the tea bar machine, the setting of the third check valve 330 can prevent the high temperature water flowing out of the ambient temperature switching valve 320 from flowing back to the ambient temperature water pump 310, thus avoiding the impact or damage of the high temperature water flow to the ambient temperature water pump 310, and also preventing some high temperature water flow from leaking into the water storage container 840 through the ambient temperature water pump 310.

[0044] In this embodiment, a cleaning water pump 510 is provided on the second cleaning pipeline 500. When the tea bar machine is in self-cleaning mode, the second cleaning pipeline 500 draws water from the hot water outlet pipeline 200 to the room temperature outlet pipeline 300 through the cleaning water pump 510. That is, when the tea bar machine is in self-cleaning mode, the cleaning water pump 510 can assist the water flow to circulate quickly in the water circuit components for sterilization and cleaning.

[0045] In addition to the above-described features, the water system component of this embodiment may further include a drain pipe 700. The inlet end of the drain pipe 700 is connected to the second cleaning pipe 500 between the cleaning water pump 510 and the ambient temperature switching valve 320. When the tea bar machine is in self-cleaning mode and needs to discharge wastewater from the water system component, the ambient temperature switching valve 320 can be switched to the position connecting the ambient temperature water pump 310 and the second water outlet connector 120. At this time, the wastewater in the second cleaning pipe 500 is blocked by the ambient temperature switching valve 320 and no longer enters the ambient temperature water outlet pipe 300, but is discharged through the drain pipe 700. By setting up the drain pipe 700, all wastewater in the water system component can be discharged by simply switching the ambient temperature switching valve 320, avoiding residual wastewater in the water system component. A second solenoid valve 710 and a water collection box 720 are provided on the drain pipe 700. The water collection box 720 is used to collect wastewater. The second solenoid valve 710 is located upstream of the water collection box 720 to open and close the drain pipe 700. When high-temperature water flows through the water system assembly for sterilization and cleaning, the second solenoid valve 710 cuts off the drain pipe 700 to prevent water from flowing out of the drain pipe 700. When it is necessary to discharge the wastewater after cleaning the water system assembly, the second solenoid valve 710 is opened so that it no longer cuts off the drain pipe 700, and all the wastewater flows into the water collection box 720 for centralized collection. Of course, it is understood that the use of a drain pipe is the preferred implementation method of this embodiment. In other embodiments, the water system assembly may not have a drain pipe to discharge wastewater.

[0046] In addition to the above, the ambient temperature water outlet pipe 300 of this embodiment may also be equipped with an ice tank 340. The ice tank 340 is connected between the ambient temperature water pump 310 and the ambient temperature switching valve 320, which can cool the water flowing from the ambient temperature water pump 310 to the ambient temperature switching valve 320. When the ice tank 340 is not working, the water flowing out of the second water outlet 120 is ambient temperature water; when the ice tank 340 is working, the water flowing out of the second water outlet 120 is cold water (i.e., water with a temperature lower than ambient temperature). Users can choose to use cold water or ambient temperature water according to their different needs, enriching the water output of the second connector and improving the user experience. The ambient temperature inlet and cold water outlet of the ice tank 340 are both connected to the ambient temperature outlet pipe 300 between the inlet of the first cleaning pipe 400 and the ambient temperature switching valve 320. Since the solenoid valve is usually suitable for ambient temperature environment, it is very easy to fail and not work when the working environment temperature is too low. Therefore, connecting the ice tank 340 between the inlet of the first cleaning pipe 400 and the ambient temperature switching valve 320 can prevent the cold water flowing out of the ice tank 340 from entering the first cleaning pipe 400, thereby preventing the cold water with too low temperature from damaging the first solenoid valve 410 and ensuring the stable operation of the first solenoid valve 410.

[0047] The water circuit assembly in this embodiment also includes a third cleaning pipe 600. A first cleaning switching valve 610 and a second cleaning switching valve 620 are respectively installed at both ends of the third cleaning pipe 600. The first cleaning switching valve 610 is connected between the ambient temperature water inlet of the ice tank 340 and the water inlet of the first cleaning pipe 600. The second cleaning switching valve 620 is connected between the cold water outlet of the ice tank 340 and the ambient temperature switching valve 320. When the user selects the mode for using cold or ambient temperature water from the tea bar machine, the first cleaning switching valve 610 switches to the position connecting the ambient temperature water pump 310 and the ambient temperature water inlet of the ice tank 340, and the second cleaning switching valve 620 switches to the position connecting the cold water outlet of the ice tank 340 and the ambient temperature switching valve 320. This allows water from the ambient temperature water pump 310 to flow into the ice tank 340 through the ambient temperature water inlet, flow through the cold water outlet to the ambient temperature switching valve 320, and finally flow out through the second water outlet connector 120. When the user selects the self-cleaning mode of the tea bar machine, the first cleaning switching valve 610 switches to the position connecting the first cleaning pipe 400 and the third cleaning pipe 600, and the second cleaning switching valve 620 switches to the position connecting the third cleaning pipe 600 and the ambient temperature switching valve 320. This allows the high-temperature water flow from the ambient temperature switching valve 320 to flow through the third cleaning pipe 600 to the first cleaning pipe 400. In other words, when the tea bar machine is in self-cleaning mode, the high-temperature water flow can bypass the ice tank 340 through the third cleaning pipe 600, thus preventing wastewater used for cleaning the water system components from flowing into the ice tank 340 and causing it to be difficult to drain or damaging the ice tank 340. It is understood that the ice tank and the third cleaning pipe are the preferred embodiments of this example. In other embodiments, the water system components may also be implemented without an ice tank and a third cleaning pipe, or with only an ice tank.

[0048] In this embodiment, the heating element 230 is preferably a hot water tank because it has a large space for storing liquid for centralized heating. Therefore, using a hot water tank as the heating element 230 allows all the cleaning water to be delivered to the hot water tank for centralized heating when the tea bar machine is in cleaning mode, after which the hot water pump 210 can be stopped. This avoids the high-temperature water in the first cleaning pipe 400 from flowing back to the heating element 230 and mixing with the room-temperature water pumped by the hot water pump 210, which would cause a rapid drop in the temperature of the high-temperature water, thus ensuring the sterilization effect of the high-temperature water. Simultaneously, it eliminates the need for continuous heating by the heating element 230, reducing its power consumption. Of course, it is understood that in other embodiments, the heating element 230 can also be other heating structures besides a hot water tank, such as an instant heating element. Using an instant heating element as the heating element can greatly reduce the space occupied by the heating element in the tea bar machine, thereby preventing the tea bar machine from becoming too large.

All technical solutions falling within the scope of this utility model's concept are protected.
