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 first hot water switching valve connected to the water storage container, a second hot water switching valve connected to the first water outlet connector, and a heating element connected between the first hot water switching valve and the second hot water switching valve; a normal temperature water outlet pipe connected between the water storage container and the first water outlet connector. Between the two water outlet connectors, a water supply system is provided for the second water outlet connector. This system includes a first ambient temperature switching valve connected to a water storage container and a second ambient temperature switching valve connected to the second water outlet connector. A first cleaning pipeline connects the first hot water switching valve and the first ambient temperature switching valve. A second cleaning pipeline connects the second hot water switching valve and the second ambient temperature switching valve. When the tea bar machine is in self-cleaning mode, water from the hot water outlet pipeline flows through the second cleaning pipeline into the ambient temperature outlet pipeline, and finally returns to the hot water outlet pipeline through the first cleaning pipeline, thus circulating and cleaning the water system components. This technical solution has the following technical effects:

[0006] This invention incorporates a heating element on the hot water outlet pipe. When a user selects hot water, the water in the storage container is preheated at the heating element as it flows through the outlet pipe before flowing 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 to heat the water to the set temperature, thus reducing the user's waiting time and enhancing the user experience. Simultaneously, a first cleaning pipe connects to a first hot water switching valve and a first ambient temperature switching valve, and a second cleaning pipe connects to a second hot water switching valve. The system includes a second ambient temperature switching valve, allowing users to select a self-cleaning mode when no water is being used. In this mode, the water circuit components can switch between the first hot water switching valve, the second hot water switching valve, the first ambient temperature switching valve, and the second ambient temperature switching valve to create a sterilization water circuit. The heating element heats the flowing water to generate a high-temperature water flow, which circulates within the sterilization water circuit and is eventually discharged, thus achieving sterilization and cleaning of the water circuit components. Users can periodically select the self-cleaning mode to sterilize and clean the water circuit components, effectively preventing bacterial growth inside the tea bar machine and ensuring safer drinking water.

[0007] In the aforementioned tea bar machine, the water system assembly also includes a water intake pipe. This water intake pipe is equipped with a water system switching valve and a water pump connected to a water storage container. The water system switching valve is connected to a first hot water switching valve, a first ambient temperature switching valve, and the water pump, respectively, to control the water flow drawn by the water pump into either the hot water outlet pipe or the ambient temperature outlet pipe. By switching positions, the water system switching valve can control the water flow drawn by the water pump into either the hot water outlet pipe or the ambient temperature outlet pipe, allowing the hot water outlet pipe and the ambient temperature outlet pipe to share the same section of pipe and water pump to draw water from the water storage container. This also prevents water from simultaneously entering the hot water outlet pipe and the ambient temperature outlet pipe, thus avoiding mutual interference and simplifying the structure of the water system assembly.

[0008] 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.

[0009] 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 second ambient temperature switching valve, so as to discharge the wastewater from cleaning the water system component through the drain pipe. When the tea bar machine is in self-cleaning mode and needs to discharge wastewater from the water system component, the second ambient temperature switching valve can be switched to the position connecting the first ambient temperature switching valve and the second water outlet connector. At this time, the wastewater is blocked by the second ambient temperature switching valve and no longer enters the ambient temperature water outlet pipe, but is discharged through the second cleaning pipe. By setting up a drain pipe, switching the second ambient temperature switching valve alone can complete the discharge of all wastewater from the water system component, avoiding the retention of wastewater in the water system component.

[0010] 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 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 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.

[0011] In the aforementioned tea bar machine, the heating element is a hot water tank; or, the heating element is an instant heating element. Because the hot water tank has a large space for storing liquid for centralized heating, using a hot water tank as the heating element allows the first hot water switching valve, which connects the water storage container and the heating element, to quickly switch to connect the first cleaning pipeline and the heating element after all the cleaning water has been centrally heated in the cleaning mode. This prevents water pressure increases in the first cleaning pipeline due to delayed switching of the first hot water switching valve. Simultaneously, the water centrally heated in the hot water tank reaches a higher temperature, resulting in better sterilization of the water system components. Using an instant heating element significantly reduces the space occupied by the heating element in the tea bar machine, thus preventing the machine from becoming too bulky.

[0012] In the aforementioned tea bar machine, the ambient temperature water outlet pipe is also equipped with an ice tank, which is connected between the first ambient temperature switching valve and the second ambient temperature switching valve to cool the water flowing to the second water outlet connector. 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. 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 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, respectively. The first cleaning switching valve is connected between the ambient temperature inlet of the ice tank and the first ambient temperature switching valve, while the second cleaning switching valve is connected between the cold water outlet of the ice tank and the second ambient temperature switching valve. When the user selects the self-cleaning mode of the tea bar machine, the high-temperature water flow from the second ambient temperature switching valve flows through the third cleaning pipe to the first ambient temperature switching valve. That is, when the tea bar machine is in self-cleaning mode, 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 being difficult to drain or damaging the ice tank.

[0014] The aforementioned tea bar machine includes a cabinet housing a water storage container and a back panel mounted on top of the cabinet. A first hot water switching valve, a second hot water switching valve, a first ambient temperature switching valve, and a second ambient temperature switching valve are all located within the back panel. This design avoids occupying excessive cabinet space and thus prevents the cabinet from becoming too large.

[0015] The aforementioned tea bar machine includes a cabinet with a middle plate. The middle plate divides the interior of the cabinet into a receiving cavity containing a water storage container and an installation cavity located above the receiving cavity. The heating element and ice tank are located in the installation cavity. The middle plate separates the water circuit components and the water storage container, which is both aesthetically pleasing and protective of the water circuit components, preventing users from bumping into them when changing the water storage container.

[0031] 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 first hot water switching valve connected to the water storage container, a second hot water switching valve connected to the first water outlet connector, and a heating element connected between the first hot water switching valve and the second hot water switching valve; 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 provided with a first normal temperature switching valve connected to the water storage container and a second normal temperature switching valve connected to the second water outlet connector; a first cleaning pipe connected between the first hot water switching valve and the first normal temperature switching valve; and a second cleaning pipe connected between the second hot water switching valve and the second 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 water outlet pipe through the second cleaning pipe and finally flows back to the hot water outlet pipe through the first cleaning pipe to circulate and clean the water circuit assembly. This invention incorporates a heating element on the hot water outlet pipe. When a user selects hot water, the water in the storage container is preheated at the heating element as it flows through the outlet pipe before flowing 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 to heat the water to the set temperature, thus reducing the user's waiting time and enhancing the user experience. Simultaneously, a first cleaning pipe connects to a first hot water switching valve and a first ambient temperature switching valve, and a second cleaning pipe connects to a second hot water switching valve. The system includes a second ambient temperature switching valve, allowing users to select a self-cleaning mode when no water is being used. In this mode, the water circuit components can switch between the first hot water switching valve, the second hot water switching valve, the first ambient temperature switching valve, and the second ambient temperature switching valve to create a sterilization water circuit. The heating element heats the flowing water to generate a high-temperature water flow, which circulates within the sterilization water circuit and is eventually discharged, thus achieving sterilization and cleaning of the water circuit components. Users can periodically select the self-cleaning mode to sterilize and clean the water circuit components, effectively preventing bacterial growth inside the tea bar machine and ensuring safer drinking water.

[0037] Example 1:

[0038] A tea bar machine, such as Figures 1 to 3As shown, the system includes a cabinet 100, a back panel 200 installed on the top of the cabinet 100, a water storage container 300, and a water circuit assembly. The water storage container 300, used to hold drinking water, is located inside the cabinet 100. A kettle 140 and a room temperature kettle are placed on the cabinet 100. The water circuit assembly is used to transfer water from the water storage container 300 to the kettle 140 and the room temperature kettle. It has two water outlet connectors located on the top of the cabinet 100 or on the back panel 200, namely a first water outlet connector 410 supplying water to the kettle 140 and a second water outlet connector 420 supplying water to the room temperature kettle. The water circuit assembly includes a hot water outlet pipe 500, a room temperature water outlet pipe 600, a first cleaning pipe 710, and a second cleaning pipe 720. A hot water outlet pipe 500 is connected between the water storage container 300 and the first outlet connector 410 to supply water to the first outlet connector 410. The hot water outlet pipe 500 is equipped with a first hot water switching valve 510, a second hot water switching valve 520, and a heating element 530. The first hot water switching valve 510 is connected to the water storage container 300, the second hot water switching valve 520 is connected to the first outlet connector 410, and the heating element 530 is connected between the first hot water switching valve 510 and the second hot water switching valve 520. A normal temperature water outlet pipe 600 is connected to the water storage container 300. Between the first hot water switch 510 and the second water outlet 420, water is supplied to the second water outlet 420. The normal temperature water outlet pipeline 600 is provided with a first normal temperature switching valve 610 and a second normal temperature switching valve 620 connected together. The first normal temperature switching valve 610 is connected to the water storage container 300, and the second normal temperature switching valve 620 is connected to the second water outlet 420. The first cleaning pipeline 710 is connected between the first hot water switching valve 510 and the first normal temperature switching valve 610. The second cleaning pipeline 720 is connected between the second hot water switching valve 520 and the second normal temperature switching valve 620.

[0039] When the user selects the mode for obtaining hot water from the tea bar machine, the first hot water switching valve 510 switches to the position connecting the water storage container 300 and the heating element 530, and the second hot water switching valve 520 switches to the position connecting the heating element 530 and the first water outlet connector 410. This allows the water in the water storage container 300 to flow into the heating element 530 for preheating through the first hot water switching valve 510 of the hot water outlet pipe 500, and then flow through the second hot water switching valve 520 to the first water outlet connector 410, so that the water can be directed to the kettle 140 placed on the top of the cabinet 100 for heating.

[0040] When a user selects the mode for using room temperature water from the tea bar machine, the first room temperature switching valve 610 switches to the position connecting the water storage container 300 and the second room temperature switching valve 620, and the second room temperature switching valve 620 switches to the position connecting the first room temperature switching valve 610 and the second water outlet connector 420. This allows the water in the water storage container 300 to flow sequentially through the first room temperature switching valve 610 and the second room temperature switching valve 620 of the room temperature water outlet pipe 600 to the second water outlet connector 420, so that the water can be directed through the second water outlet connector 420 into the room temperature kettle placed on the top of the cabinet 100 for the user to use.

[0041] When the user selects the self-cleaning mode of the tea bar machine, the first hot water switching valve 510 switches to the position connecting the water storage container 300 and the heating element 530; the second hot water switching valve 520 switches to the position connecting the heating element 530 and the second cleaning pipe 720; the second ambient temperature switching valve 620 switches to the position connecting the second cleaning pipe 720 and the first ambient temperature switching valve 610; and the first ambient temperature switching valve 610 switches to the position connecting the second ambient temperature switching valve 620 and the first cleaning pipe 710. Figure 3 As shown by the arrow, the water in the water storage container 300 flows into the heating element 530 through the first hot water switching valve 510 of the hot water outlet pipe 500 and is heated into a high-temperature water flow. Then, the high-temperature water flow flows through the second hot water switching valve 520 to the second cleaning pipe 720, and then flows through the second normal temperature switching valve 620 and the first normal temperature switching valve 610 to the first cleaning pipe 710. Before the water flows out of the first cleaning pipe 710, the first hot water switching valve 510 is switched to the position connecting the first cleaning pipe 710 and the heating element 530, so that the high-temperature water flow in the first cleaning pipe 710 flows back to the heating element 530. That is, the high-temperature water flow circulates sequentially in the hot water outlet pipe 500, the second cleaning pipe 720, the normal temperature outlet pipe 600 and the first cleaning pipe 710 to achieve the circulation and sterilization cleaning of the high-temperature water flow in the water circuit components. During this process, the heating element 530 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, by installing a heating element 530 on the hot water outlet pipe 500, ensures that when a user selects hot water, the water in the storage container 300 is preheated at the heating element 530 as it flows through the hot water outlet pipe 500, and then flows through the first water outlet connector 410 into the kettle 140 placed on top of the tea bar machine for heating. This improves the heating efficiency of the kettle 140 and shortens the time required for the kettle 140 to heat the water to the set temperature, thus reducing the user's waiting time and improving the user experience. Simultaneously, a first hot water switching valve 510 and a first normal temperature switching valve 610 are connected through a first cleaning pipe 710, and a second cleaning pipe 720 is also included. The connection between the second hot water switching valve 520 and the second ambient temperature switching valve 620 allows users to select the self-cleaning mode when no water is being used. In this mode, the water circuit components can form a sterilization water circuit by switching between the first hot water switching valve 510, the second hot water switching valve 520, the first ambient temperature switching valve 610, and the second ambient temperature switching valve 620. The heating element 530 can heat the flowing water to generate a high-temperature water flow. The high-temperature water flow circulates in the sterilization water circuit and is eventually discharged, thereby achieving sterilization and cleaning of the water circuit components. Users can periodically select the self-cleaning mode to sterilize and clean the water circuit components, effectively preventing bacteria from growing in the water circuit components inside the tea bar machine, making drinking water safer.

[0043] In this embodiment, as Figure 1 As shown, the water system assembly also includes a water intake pipe 800, which is equipped with a water system switching valve 820 and a water pump 810. The water pump 810 is located upstream of the water system switching valve 820 and connected to the water storage container 300. The water system switching valve 820 is connected to a first hot water switching valve 510, a first ambient temperature switching valve 610, and the water pump 810. When the water system switching valve 820 is in the position connecting the water pump 810 and the first hot water switching valve 510, the water pumped by the water pump 810 enters the hot water outlet pipe 500 through the water system switching valve 820; when the water system switching valve 820 is in the position connecting the water pump 810 and the first hot water switching valve 510, the water pumped by the water pump 810 enters the hot water outlet pipe 500 through the water system switching valve 820; when the water system switching valve 820 is in the position connecting the water pump 810 and the first hot water switching valve 510, the water pumped by the water pump 810 enters the hot water outlet pipe 500 through the water system switching valve 820. When the water pump 810 and the second hot water switching valve 520 are connected, the water pumped by the water pump 810 enters the ambient temperature outlet pipe 600 through the water switching valve 820. By switching the position, the water switching valve 820 can control the water pumped by the water pump 810 to enter the hot water outlet pipe 500 or the ambient temperature outlet pipe 600, so that the hot water outlet pipe 500 and the ambient temperature outlet pipe 600 can share the same section of pipe and water pump to draw water from the water storage container 300. At the same time, it avoids water from entering the hot water outlet pipe 500 and the ambient temperature outlet pipe 600 at the same time, which would cause mutual interference and simplify the structure of the water circuit components.

[0044] In this embodiment, a cleaning water pump 721 is provided on the second cleaning pipe 720. When the tea bar machine is in self-cleaning mode, the second cleaning pipe 720 draws water from the hot water outlet pipe 500 to the room temperature outlet pipe 600 through the cleaning water pump 721. When the tea bar machine is in self-cleaning mode, the cleaning water pump 721 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 900. The inlet end of the drain pipe 900 is connected to the second cleaning pipe 720 between the cleaning water pump 721 and the second ambient temperature switching valve 620. When the tea bar machine is in self-cleaning mode and needs to discharge wastewater from the water system component, the second ambient temperature switching valve 620 can be switched to a position connecting the first ambient temperature switching valve 610 and the second water outlet connector 420. At this time, the wastewater is blocked by the second ambient temperature switching valve 620 and no longer enters the ambient temperature water outlet pipe 600, but is discharged through the second cleaning pipe 720. By setting up the drain pipe 900, switching the second ambient temperature switching valve 620 alone can complete the discharge of all wastewater from the water system component, avoiding residual wastewater in the water system component.

[0046] A solenoid valve 910 and a water collection box 920 are installed on the drain pipe 900. The water collection box 920 is used to collect wastewater. The solenoid valve 910 is located upstream of the water collection box 920 to open and close the drain pipe 900. When high-temperature water circulates and sterilizes the water system components, the solenoid valve 910 cuts off the drain pipe 900 to prevent water from flowing out. When it is necessary to discharge the wastewater after cleaning the water system components, the solenoid valve 910 is opened so that it no longer cuts off the drain pipe 900, and all the wastewater flows into the water collection box 920 for centralized collection. Preferably, the water collection box 920 is located inside the receiving cavity 120, and the top of the water collection box 920 is installed on the cabinet 100. By placing the water collection box 920 inside the receiving cavity 120, the user can easily remove the water collection box 920 from the receiving cavity 120 by opening the cabinet door to empty the wastewater, making the operation more convenient. Of course, it is understood that using a drainage pipe is the preferred implementation method in this embodiment. In other embodiments, the water system may also discharge wastewater without a drainage pipe.

[0047] In this embodiment, the heating element 530 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 530 allows for quick switching of the first hot water switching valve 510 (connecting the water storage container 300 and the heating element 530) to the position connecting the first cleaning pipe 710 and the heating element 530 after all the cleaning water has been delivered to the hot water tank for centralized heating when the tea bar machine is in cleaning mode. This prevents water pressure increases in the first cleaning pipe 710 due to delayed switching of the first hot water switching valve 510. Simultaneously, the water heated centrally in the hot water tank can be heated to a higher temperature, resulting in better sterilization of the water system components. Of course, it is understood that in other embodiments, the heating element can be any heating structure other than a hot water tank, such as an instant heating element. Using an instant heating element can significantly reduce the space occupied by the heating element in the tea bar machine, thereby preventing the tea bar machine from becoming too large.

[0048] In addition to the above, the ambient temperature water outlet pipe 600 of this embodiment may also be equipped with an ice tank 630. The ice tank 630 is connected between the first ambient temperature switching valve 610 and the second ambient temperature switching valve 620, and can cool the water flowing from the first ambient temperature switching valve 610 to the second ambient temperature switching valve 620. When the ice tank 630 is not working, the water flowing out of the second water outlet 420 is ambient temperature water; when the ice tank 630 is working, the water flowing out of the second water outlet 420 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.

[0049] The water circuit assembly in this embodiment also includes a third cleaning pipe 730. The third cleaning pipe 730 has a first cleaning switching valve 731 and a second cleaning switching valve 732 at its two ends. The first cleaning switching valve 731 is connected between the ambient temperature inlet of the ice tank 630 and the first ambient temperature switching valve 610. The second cleaning switching valve 732 is connected between the cold water outlet of the ice tank 630 and the second ambient temperature switching valve 620. When the user selects the mode for using cold or ambient temperature water from the tea bar machine, the first cleaning switching valve 731 switches to a position connecting the first ambient temperature switching valve 610 and the ambient temperature inlet of the ice tank 630, and the second cleaning switching valve 732 switches to a position connecting the cold water outlet of the ice tank 630 and the second water outlet connector 420. Water from the first ambient temperature switching valve 610 flows into the ice tank 630 through the ambient temperature inlet, flows to the second ambient temperature switching valve 620 through the cold water outlet, and finally flows out through the second water outlet connector 420. When the user selects the self-cleaning mode of the tea bar machine, the first cleaning switching valve 731 switches to the position connecting the first ambient temperature switching valve 610 and the third cleaning pipe 730, and the second cleaning switching valve 732 switches to the position connecting the third cleaning pipe 730 and the second ambient temperature switching valve 620. This allows the high-temperature water flow from the second ambient temperature switching valve 620 to flow through the third cleaning pipe 730 to the first ambient temperature switching valve 610. That is, when the tea bar machine is in self-cleaning mode, the high-temperature water flow can bypass the ice tank 630 through the third cleaning pipe 730, thus preventing wastewater used for cleaning the water circuit components from flowing into the ice tank 630 and being difficult to drain or damaging the ice tank 630. Of course, it is understood that the ice tank and the third cleaning pipe 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 pipe, or with only the ice tank.

[0050] like Figure 2 As shown, in this embodiment, the first hot water switching valve 510, the second hot water switching valve 520, the first ambient temperature switching valve 610, and the second ambient temperature switching valve 620 are all located within the back panel 200 to avoid occupying too much space in the cabinet 100, thereby preventing the cabinet 100 from becoming too large. Figure 1 As shown, a horizontally arranged middle plate 110 is provided inside the cabinet 100. The middle plate 110 divides the interior of the cabinet 100 into a receiving cavity 120 and an installation cavity 130. The receiving cavity 120 is located below the middle plate 110 to accommodate a water storage container 300 (such as a water bucket). A water collection box 920 is installed at the bottom of the middle plate 110. The installation cavity 130 is located above the receiving cavity 120 to accommodate a larger heating element 530 and an ice tank 630. The middle plate 110 separates the water circuit components and the water storage container 300, which is aesthetically pleasing and protects the water circuit components, preventing users from bumping into the water circuit components when replacing the water storage container 300.

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.
