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 and a hot water switching valve connected to the first water outlet connector; 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 normal temperature switching valve connected to the second water outlet connector. The system includes a first cleaning pipeline equipped with a heating element and a water switching valve located upstream of the heating element. The water switching valve is connected to the hot water outlet pipeline between the hot water pump and the hot water switching valve to control the water flow to either the hot water switching valve or the heating element. The outlet of the first cleaning pipeline is connected to the ambient temperature outlet pipeline between the ambient temperature pump and the ambient temperature switching valve. A second cleaning pipeline connects the hot water switching valve and the ambient temperature switching valve. When the tea bar machine is in self-cleaning mode, water from the hot water outlet pipeline flows through the first cleaning pipeline into the ambient temperature outlet pipeline and finally returns to the hot water outlet pipeline through the second cleaning pipeline to circulate and clean the water 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 to a first cleaning pipe and a second cleaning pipe, and installs a heating element on the first cleaning pipe. This allows users to select a self-cleaning mode when no water is being used. In this mode, a sterilization water path is formed inside the water system by switching between a hot water switching valve, a normal temperature switching valve, and a water path switching valve. The heating element heats the flowing water to generate a high-temperature water flow, which circulates within the sterilization water path and is eventually discharged, thus achieving sterilization and cleaning of the water system. This allows users to clean the water system periodically. Selecting the self-cleaning mode sterilizes and cleans the water system components, effectively preventing bacterial growth inside the tea bar machine and ensuring safer drinking water. Simultaneously, because the heating element is located on the first cleaning pipe, when the user takes hot water, the water flowing from the storage container to the first outlet is blocked by the water switching valve and does not pass through the heating element on the first cleaning water line. This prevents wastewater remaining in the heating element from flowing out with the water from the first outlet, thus avoiding contamination of the user's drinking water with the wastewater generated by the self-cleaning mode and ensuring the cleanliness of the user's drinking water.

[0007] In the aforementioned tea bar machine, a cleaning water pump located downstream of the heating element is also provided on the first cleaning pipeline. When the tea bar machine is in self-cleaning mode, the first cleaning pipeline draws water from the hot water outlet pipeline to the room temperature outlet pipeline through the cleaning water pump. The cleaning water pump can pressurize the water flow to assist the water flow in rapid circulation within the water circuit components for sterilization and cleaning.

[0008] In the aforementioned tea bar machine, the water system also includes a water supply pipe equipped with a first solenoid valve. The inlet end of the water supply pipe is connected to the hot water outlet pipe upstream of the hot water pump, and the outlet end of the water supply pipe is connected to the first cleaning pipe between the water system switching valve and the heating element. When the tea bar machine is in self-cleaning mode, after the hot water pump stops working, the first solenoid valve can be opened to connect the water supply pipe to the water storage container and the heating element. Water from the water storage container is drawn through the water supply pipe to replenish the heating element for heating. After replenishing a certain amount of water, the first solenoid valve is closed to ensure that there is a sufficient flow of high-temperature water to sterilize and clean the water system components, ensuring the sterilization and cleaning effect.

[0009] In the aforementioned tea bar machine, a first check valve is installed on the ambient temperature water outlet pipe, connecting the ambient temperature water pump and the outlet of the first cleaning pipe. A second check valve is installed on the first cleaning pipe, located downstream of the cleaning water pump. When the user selects the self-cleaning mode of the tea bar machine, the first check valve prevents the high-temperature water flowing out of the first cleaning pipe from flowing back to the ambient temperature water pump, avoiding impact or damage to the ambient temperature water pump, and also preventing some high-temperature water from leaking into the water storage container through the ambient temperature water pump. The second check valve, when the user selects the ambient temperature water outlet mode of the tea bar machine, prevents water from flowing from the ambient temperature water outlet pipe to the cleaning water pump of the first cleaning pipe, avoiding impact or damage to the cleaning water pump, and also preventing some water from leaking into the heating element through the cleaning water pump.

[0010] In the aforementioned tea bar machine, the water system also includes a drain pipe. The inlet end of the drain pipe is connected to the second cleaning pipe to discharge wastewater from cleaning the water system. When the tea bar machine is in self-cleaning mode and needs to discharge wastewater from the water system, the ambient temperature switching valve can be switched to the position connecting the ambient temperature outlet pipe and the second outlet connector. At this time, the wastewater is blocked by the ambient temperature switching valve and no longer enters the ambient temperature outlet pipe, but is discharged through the drain pipe, resulting in good drainage.

[0011] In the aforementioned tea bar machine, a second solenoid valve and a water collection box for collecting wastewater are installed on the drain pipe. The second 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, the machine includes a cabinet and a back panel mounted on the cabinet. The cabinet contains a cavity for accommodating a water storage container, and a water collection box is located within this cavity. By placing the water collection box within the cavity, users can easily remove the box from the cabinet to empty the wastewater, making operation more convenient.

[0013] 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.

[0014] In the aforementioned tea bar machine, the ice tank is connected between the ambient temperature water pump and the ambient temperature switching valve, and the ambient temperature water inlet of the ice tank is located downstream of the first cleaning pipeline. Positioning the ambient temperature water inlet of the ice tank downstream of the first cleaning pipeline prevents cold water flowing from the ice tank from entering the heating element of the first cleaning pipeline, thereby preventing excessively cold water from affecting the normal operation of the heating element.

[0015] 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 is connected between the ambient temperature water inlet of the ice tank and the outlet of the first cleaning pipe, while the second cleaning switching valve is connected between the cold water outlet of the ice tank and 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 first cleaning pipe flows through the third cleaning pipe to the ambient temperature switching valve. That is, the high-temperature water flow can bypass the ice tank through the third cleaning pipe, 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.

[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

[0030] 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 equipped with a hot water pump connected to the water storage container and a hot water switching valve connected to the first water outlet connector; 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, which is equipped with a normal temperature water pump connected to the water storage container and a normal temperature switching valve connected to the second water outlet connector; and a first cleaning pipe. It is equipped with a heating element and a water switching valve located upstream of the heating element. The water switching valve is connected to the hot water outlet pipe between the hot water pump and the hot water switching valve to control the water flow to the hot water switching valve or the heating element. The outlet end of the first cleaning pipe is connected to the normal temperature outlet pipe between the normal temperature pump and the normal temperature switching valve. The second cleaning pipe is 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 in the hot water outlet pipe flows into the normal temperature outlet pipe through the first cleaning pipe and finally flows back to the hot water outlet pipe through the second cleaning pipe to circulate and clean the water components. This invention connects a hot water outlet pipe and a normal temperature water outlet pipe to a first cleaning pipe and a second cleaning pipe, and installs a heating element on the first cleaning pipe. This allows users to select a self-cleaning mode when no water is being used. In this mode, a sterilization water path is formed inside the water system by switching between a hot water switching valve, a normal temperature switching valve, and a water path switching valve. The heating element heats the flowing water to generate a high-temperature water flow, which circulates within the sterilization water path and is eventually discharged, thus achieving sterilization and cleaning of the water system. This allows users to clean the water system periodically. Selecting the self-cleaning mode sterilizes and cleans the water system components, effectively preventing bacterial growth inside the tea bar machine and ensuring safer drinking water. Simultaneously, because the heating element is located on the first cleaning pipe, when the user takes hot water, the water flowing from the storage container to the first outlet is blocked by the water switching valve and does not pass through the heating element on the first cleaning water line. This prevents wastewater remaining in the heating element from flowing out with the water from the first outlet, thus avoiding contamination of the user's drinking water with the wastewater generated by the self-cleaning mode and ensuring the cleanliness of the user's drinking water.

[0036] Example 1:

[0037] A tea bar machine, such as Figures 1 to 2 As shown, the system includes a cabinet 110, a back panel 120 mounted on the top of the cabinet 110, a water storage container 130, and a water circuit assembly. The water storage container 130, used to hold drinking water, is located inside the cabinet 110. A kettle 140 and a room temperature kettle are placed on the cabinet 110. The water circuit assembly is used to transfer water from the water storage container 130 to the kettle 140 and the room temperature kettle. It has two water outlet connectors located on the top of the cabinet 110 or on the back panel 120, namely a first water outlet connector 210 for supplying water to the kettle 140 and a second water outlet connector 220 for supplying water to the room temperature kettle. The water circuit assembly includes a hot water outlet pipe 300, a room temperature water outlet pipe 400, a first cleaning pipe 500, and a second cleaning pipe 600.

[0038] A hot water outlet pipe 300 is connected between the water storage container 130 and the first outlet connector 210 to supply water to the first outlet connector 210. The hot water outlet pipe 300 is equipped with a hot water pump 310 and a hot water switching valve 320. The hot water pump 310 is connected to the water storage container 130, and the hot water switching valve 320 is connected to the first outlet connector 210. A normal temperature water outlet pipe 400 is connected between the water storage container 130 and the second outlet connector 220 to supply water to the second outlet connector 220. The normal temperature water outlet pipe 400 is equipped with a normal temperature water pump 410 and a normal temperature switching valve 420. The normal temperature water pump 410 is connected to the water storage container 130, and the normal temperature switching valve 420 is connected to the second outlet connector 220. The first cleaning pipeline 500 is equipped with a connected heating element 510 and a water circuit switching valve 520. The water circuit switching valve 520 is located upstream of the heating element 510 and is connected to the hot water outlet pipeline 300 between the hot water pump 310 and the hot water switching valve 320. The water circuit switching valve 520 controls the flow of water in the hot water outlet pipeline 300 to the hot water switching valve 320 or the heating element 510 by switching the water circuit. The outlet end of the first cleaning pipeline 500 is connected to the normal temperature outlet pipeline 400 between the normal temperature pump 410 and the normal temperature switching valve 420. The second cleaning pipeline 600 is connected between the hot water switching valve 320 and the normal temperature switching valve 420.

[0039] When the user selects the mode for obtaining hot water from the tea bar machine, the water circuit switching valve 520 switches to the position connecting the hot water pump 310 and the hot water switching valve 320. The hot water switching valve 320 switches to the position connecting the water circuit switching valve 520 and the first water outlet connector 210. The hot water pump 310 operates, and the water pumped by the hot water pump 310 flows through the water circuit switching valve 520 and the hot water switching valve 320 to the first water outlet connector 210, so that the water flow can be introduced into the kettle 140 placed on the top of the cabinet 110 for heating.

[0040] When the user selects the mode for using room temperature water from the tea bar machine, the room temperature switching valve 420 switches to the position connecting the room temperature water pump 410 and the second water outlet connector 220. The room temperature water pump 410 operates, and the water pumped by the room temperature water pump 410 flows through the room temperature switching valve 420 of the room temperature water outlet pipeline 400 to the second water outlet connector 220, so that the water is introduced into the room temperature water jug ​​placed on the top of the cabinet 110 for the user to use.

[0041] When the user selects the self-cleaning mode of the tea bar machine, the water circuit switching valve 520 first switches to the position connecting the hot water pump 310 and the first cleaning pipe 500, and the ambient temperature switching valve 420 switches to the position connecting the ambient temperature outlet pipe 400 and the second cleaning pipe 600. Figure 2 As indicated by the arrow, the water pumped by the hot water pump 310 flows into the heating element 510 through the water circuit switching valve 520 and is heated into a high-temperature water flow. Then, the high-temperature water flow flows through the normal temperature switching valve 420 to the second cleaning pipe 600, and then flows to the hot water switching valve 320. Before the high-temperature water flow enters the water circuit switching valve 520, the water circuit switching valve 520 switches to the position connecting the hot water switching valve 320 and the first cleaning pipe 500. Then, the hot water pump 310 stops working, so that the high-temperature water flow flows back from the hot water switching valve 320 to the first cleaning pipe 500. That is, the high-temperature water flow circulates sequentially in the hot water outlet pipe 300, the first cleaning pipe 500, the normal temperature outlet pipe 400, and the second cleaning pipe 600 to achieve the circulation and sterilization cleaning of the high-temperature water flow in the water circuit components. During this process, the heating element 510 can heat continuously or heat for a short time to keep the high-temperature water flow 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.

[0042] This invention connects a hot water outlet pipe 300 and a normal temperature water outlet pipe 400 to a first cleaning pipe 500 and a second cleaning pipe 600, respectively. A heating element 510 is installed on the first cleaning pipe 500, allowing the user to select a self-cleaning mode when no water is being used. In this mode, a sterilization water path is formed inside the water system by switching between a hot water switching valve 320, a normal temperature switching valve 420, and a water path switching valve 520. The heating element 510 heats the flowing water to generate a high-temperature water flow. This high-temperature water circulates within the sterilization water path and is eventually discharged, achieving sterilization and cleaning of the water system components, allowing the user to enjoy a clean and comfortable experience. By regularly selecting the self-cleaning mode to sterilize and clean the water circuit components, bacteria can be effectively prevented from growing inside the water circuit components of the tea bar machine, making drinking water safer. At the same time, because the heating element 510 is located on the first cleaning pipe 500, when the user takes hot water, the water flowing from the water storage container 130 to the first water outlet 210 will not pass through the heating element 510 on the first cleaning water circuit due to the obstruction of the water circuit switching valve 520. This prevents the wastewater remaining in the heating element 510 from the self-cleaning mode from flowing out with the water flow from the first water outlet 210, thus preventing the user's drinking water from being mixed with the wastewater generated by the self-cleaning mode and ensuring the cleanliness of the user's drinking water.

[0043] In this embodiment, a cleaning water pump 530 is also provided on the first cleaning pipe 500. The cleaning water pump 530 is located downstream of the heating element 510. When the tea bar machine is in self-cleaning mode, the first cleaning pipe 500 draws water from the hot water outlet pipe 300 to the room temperature outlet pipe 400 through the cleaning water pump 530. The cleaning water pump 530 can pressurize the water flow to assist the water flow in rapid circulation within the water circuit components for sterilization and cleaning.

[0044] Based on the above, the water circuit assembly of this embodiment may further include a water supply pipe 900 equipped with a first solenoid valve 910. The inlet end of the water supply pipe 900 is connected to the hot water outlet pipe 300 upstream of the hot water pump 310, and the outlet end of the water supply pipe 900 is connected to the first cleaning pipe 500 between the water circuit switching valve 520 and the heating element 510. The first solenoid valve 910 is normally closed to prevent water from flowing back into the water storage container 130 when the tea bar machine is working. When the tea bar machine is in self-cleaning mode, after the hot water pump 310 stops working, the first solenoid valve 910 can be opened to connect the water supply pipe 900 to the water storage container 130 and the heating element 510. The cleaning water pump 530 draws water from the water storage container 130 through the water supply pipe 900 to supplement the heating element 510 for heating. After the water supply reaches a certain amount, the first solenoid valve 910 is closed to ensure that there is a sufficient amount of high-temperature water to sterilize and clean the water circuit components, ensuring the sterilization and cleaning effect.

[0045] In this embodiment, the ambient temperature water outlet pipe 400 is also equipped with a first one-way valve 430 connected between the ambient temperature water pump 410 and the outlet of the first cleaning pipe 500. The outlet of the first cleaning pipe 500 is located between the outlet of the first one-way valve 430 and the second switching valve. When the user selects the self-cleaning mode of the tea bar machine, the setting of the first one-way valve 430 can prevent the high temperature water flowing out of the first cleaning pipe 500 from flowing back to the ambient temperature water pump 410, avoid the high temperature water flow from impacting or damaging the ambient temperature water pump 410, and also prevent some high temperature water flow from leaking into the water storage container 130 through the ambient temperature water pump 410. The first cleaning pipeline 500 is equipped with a second one-way valve 540 located downstream of the cleaning water pump 530. The second one-way valve 540 can prevent the water in the normal temperature water outlet pipeline 400 from flowing to the cleaning water pump 530 of the first cleaning pipeline 500 when the user selects the normal temperature water outlet mode of the tea bar machine, so as to avoid the water flow from impacting or damaging the cleaning water pump 530, and also to prevent some water from leaking into the heating element 510 through the cleaning water pump 530.

[0046] In addition to the above-described features, the water system component of this embodiment may further include a drain pipe 800. The inlet end of the drain pipe 800 is connected to the second cleaning pipe 600. 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 420 can be switched to the position connecting the ambient temperature outlet pipe 400 and the second outlet connector 220. At this time, the wastewater is blocked by the ambient temperature switching valve 420 and no longer enters the ambient temperature outlet pipe 400, but is discharged through the drain pipe 800, resulting in good drainage. Of course, it is understood that using a drain pipe is the preferred implementation method of this embodiment. In other embodiments, the water system component may not have a drain pipe to discharge wastewater.

[0047] A second solenoid valve 810 and a water collection box 820 are provided on the drain pipe 800. The water collection box 820 is used to collect wastewater. The second solenoid valve 810 is located upstream of the water collection box 820 to open and close the drain pipe 800. When high-temperature water flows through the water system components for sterilization and cleaning, the second solenoid valve 810 cuts off the drain pipe 800 to prevent water from flowing out of the drain pipe 800. When it is necessary to discharge the wastewater after cleaning the water system components, the second solenoid valve 810 is opened so that the second solenoid valve 810 no longer cuts off the drain pipe 800, and all the wastewater flows into the water collection box 820 for centralized collection. Preferably, the cabinet 110 has a horizontally arranged middle plate 111 and a receiving cavity 112 for accommodating the water storage container 130. The receiving cavity 112 is located below the middle plate 111, and the water collection box 820 is located in the receiving cavity 112 and installed on the middle plate 111. By placing the water collection box 820 in the receiving cavity 112, the user can open the cabinet door to remove the water collection box 820 in the receiving cavity 112 to pour out the wastewater, making the operation more convenient.

[0048] In addition to the above, the ambient temperature water outlet pipe 400 of this embodiment may also be equipped with an ice tank 440. The ice tank 440 is connected between the ambient temperature water pump 410 and the ambient temperature switching valve 420, which can cool the water flowing from the ambient temperature water pump 410 to the ambient temperature switching valve 420. The ambient temperature water inlet of the ice tank 440 is located downstream of the first cleaning pipe 500. When the ice tank 440 is not working, the water flowing out of the second water outlet connector 220 is ambient temperature water; when the ice tank 440 is working, the water flowing out of the second water outlet connector 220 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. Because the water pump cannot work in a low-temperature environment, the normal temperature water inlet of the ice tank 440 is set downstream of the first cleaning pipeline 500. This can prevent the cold water flowing out of the ice tank 440 from entering the cleaning water pump 530 or the heating element 510 of the first cleaning pipeline 500, thereby preventing the cleaning water pump 530 or the heating element 510 from malfunctioning due to excessively low temperature cold water.

[0049] The water circuit assembly in this embodiment also includes a third cleaning pipe 700. The two ends of the third cleaning pipe 700 are respectively equipped with a first cleaning switching valve 710 and a second cleaning switching valve 720. The first cleaning switching valve 710 is connected between the ambient temperature water inlet of the ice tank 440 and the water outlet of the first cleaning pipe 500. The second cleaning switching valve 720 is connected between the cold water outlet of the ice tank 440 and the ambient temperature switching valve 420. When the user selects the mode for using cold or ambient temperature water from the tea bar machine, the first cleaning switching valve 710 switches to the position connecting the ambient temperature water pump 410 and the ambient temperature water inlet of the ice tank 440, and the second cleaning switching valve 720 switches to the position connecting the cold water outlet of the ice tank 440 and the ambient temperature switching valve 420. This allows water from the ambient temperature water pump 410 to flow into the ice tank 440 through the ambient temperature water inlet, flow through the cold water outlet to the ambient temperature switching valve 420, and finally flow out through the second water outlet connector 220. When the user selects the self-cleaning mode of the tea bar machine, the first cleaning switching valve 710 switches to the position connecting the normal temperature water pump 410 and the third cleaning pipeline 700, and the second cleaning switching valve 720 switches to the position connecting the third cleaning pipeline 700 and the normal temperature switching valve 420. This allows the high-temperature water flow from the first cleaning pipeline 500 to flow through the third cleaning pipeline 700 to the normal temperature switching valve 420. That is, when the tea bar machine is in self-cleaning mode, the high-temperature water flow can bypass the ice tank 440 through the third cleaning pipeline 700, thus preventing wastewater used for cleaning the water circuit components from flowing into the ice tank 440 and being difficult to drain or damaging the ice tank 440. Of course, it is understood that the ice tank and the third cleaning pipeline are the preferred embodiments of this example. In other embodiments, the water circuit components may also be implemented without the ice tank and the third cleaning pipeline, or with only the ice tank.

[0050] In this embodiment, the heating element 510 is preferably a hot tank because the hot tank has a large space for storing liquid for centralized heating. Therefore, using a hot tank as the heating element 510 allows the water flow for cleaning to be delivered to the hot tank for centralized heating when the tea bar machine is in cleaning mode. Then, the water circuit switching valve 520, which is connected to the hot water pump 310 and the first cleaning pipeline 500, can be quickly switched to the position connecting the hot water switching valve 320 and the first cleaning pipeline 500. At the same time, the water flow that is centrally heated in the hot tank can be heated to a higher temperature, resulting in a better sterilization effect on the water circuit components.

[0051] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
