Description

Technical Field

[0001] This utility model relates to the technical field of kitchen cleaning equipment, and more specifically to a trough assembly that optimizes the function of cleaning cups and utensils. Background Technology

[0002] In the existing kitchen cleaning equipment field, the sink, as the core functional area, is usually equipped with cleaning structures such as a cup washer to clean cups and other utensils, forming a sink assembly for cleaning.

[0003] Currently, most commercially available cup cleaning assemblies use a push-button start system, requiring users to continuously press a mechanical switch or touch panel to activate the cleaning program. This method has significant drawbacks in practical use: First, when users hold wet, slippery cups covered in detergent, the physical pressing action poses a risk of slipping, affecting operational safety; second, in situations requiring the continuous cleaning of multiple cups, repeated pressing can easily lead to user fatigue and reduce cleaning efficiency; third, varying pressing pressure can cause unstable water pressure, or even prevent the button from being pressed at all. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a cleaning tank assembly that optimizes the cleaning function of cups, making it easier and more convenient to clean cups.

[0005] The technical solution of this utility model is as follows:

[0006] This technical solution is proposed based on the need for cup cleaning in existing sink and other basin assemblies. It has been found that the cup cleaning device in existing basin assemblies often uses a mechanical pressing structure as the identification and switching method for cup cleaning. In actual use, when cleaning cups, there are problems such as difficulty in pressing and cleaning, easy fatigue, and unstable rinsing.

[0007] Based on this, the present invention adopts an automated solution for the identification and switching method of cup cleaning, which can automatically clean the cups as soon as they are placed, thereby optimizing the cup cleaning function and improving the convenience and stability of cup cleaning.

[0008] Specifically, the cleaning tank assembly of this utility model includes:

[0009] The tank has a main cleaning tank and a cup washing tank. The cup washing tank has a support platform, and the support platform is equipped with a weighing module for placing cups and obtaining the weight value of the placed items.

[0010] The water supply pipe into which the water flows has its outlet end inserted into the weighing module from bottom to top, and is equipped with a spray hole for spraying water from the water supply pipe upwards to the cup washing area above the weighing module.

[0011] A water control valve installed in a water supply pipeline to control the opening and closing of the water supply pipeline;

[0012] The booster pump installed in the water supply pipeline is configured to drive water in the water supply pipeline to spray out from the spray nozzle.

[0014] The main control device is electrically connected to the power supply. The weighing module, water control valve, booster pump and aerator are all electrically connected to the main control device.

[0015] The main control device is configured to: set a start threshold, compare the received weighing value with the start threshold, and when the weighing value is greater than or not greater than the start threshold, control the water control valve, booster pump and aerator to start the cup cleaning / stop the cup cleaning.

[0016] In some schemes, the main control device is set with multiple limiting thresholds that are all greater than the start threshold and increase sequentially: A1, A2.......An, where n is a value greater than or equal to 2;

[0017] The booster pump is equipped with multiple power levels that gradually increase in power, matched to a limited threshold: B1, B2, ..., Bn;

[0022] The air intake pump is electrically connected to the main control unit, which controls the air intake pump to turn on / off, thereby controlling the aerator to turn on / off.

[0023] In some solutions, the weighing module includes: a weighing sensor placed on a support platform, and a loading platform placed on the weighing sensor for placing the cups;

[0024] One end of the water pipeline is inserted into the cargo platform from bottom to top.

[0025] In some designs, the water pipeline includes:

[0027] A water supply pipe is connected to the water chamber to supply water into the water chamber, and a booster pump is installed in the water supply pipe;

[0028] The top of the water tank has a water spray unit inserted from bottom to top into the loading platform, and the spray nozzle is set in the water spray unit so that the cup washing area for washing cups and the weighing sensor are arranged vertically aligned.

[0029] In some designs, the water tank is connected to a drain pipe that communicates with the water chamber to drain the water from the water chamber;

[0030] The drain pipe is equipped with a drain control valve that controls the opening and closing of the drain pipe. The drain control valve is electrically connected to the main control device and is configured to control the drain pipe to be in a blocked state (non-draining) or a smooth state (draining) when the cup cleaning is being performed or when the cup cleaning is finished.

[0031] In some designs, the water supply pipe is connected to the side wall of the water inlet chamber, and the drain pipe is connected to the bottom wall of the water inlet chamber.

[0032] Furthermore, the bottom wall of the water-filling cavity extends horizontally, or the bottom wall of the water-filling cavity extends at an angle and forms a guide slope that guides the water in the water-filling cavity to the drain pipe.

[0033] In some designs, the platform is equipped with a vertically penetrating drainage hole to allow water on the platform to flow downwards into the cup washing tank.

[0055] The present invention will be specifically illustrated below with reference to embodiments:

[0056] Example 1:

[0057] Cleaning tank assembly, as shown in the attached document Figure 1 As shown, it mainly includes a tank body 1, and may also include a tap faucet 14 installed in the tank body 1 and used to connect to a tap water pipe. The tank body 1 is provided with an upward-facing main washing tank 1.1 and an upward-facing cup washing tank 1.2.

[0058] As attached Figure 2 As shown, a support platform 1.21 is provided in the cup washing tank 1.2. This support platform 1.21 can be a plate fixed in the cup washing tank 1.2, or it can be formed by the bottom wall of the cup washing tank 1.2. A weighing module is provided on the support platform 1.21 for placing cups and obtaining the weight value of the placed items. In addition, a water supply pipe 2 (consisting of one or more pipes connected together) is also provided for water supply. One end of the water supply pipe 2 is the water inlet end, which is used to connect to an external tap water pipe so that tap water can flow into the water supply pipe 2; the other end of the water supply pipe 2 is the water outlet end, which is inserted into the weighing module from bottom to top, and is provided with a spray hole 2a for spraying water from the water supply pipe 2 upward to the cup washing area above the weighing module.

[0059] The weighing module is a common structure in weighing systems such as electronic scales, used to obtain the weight value of the object placed on it. It mainly includes: a platform 5.2 for placing the object to be weighed, a weighing sensor 5.1 placed below the platform 5.2 to support it, and a main control unit. In this embodiment, the weighing sensor 5.1 is placed on the support platform 1.21, and the platform 5.2 is placed on the weighing sensor 5.1 and used to place the cup a.

[0060] The loading platform 5.2 is provided with a vertically penetrating insertion hole 5.22. One end (outlet end) of the water supply pipe 2 is inserted into the insertion hole 5.22 from bottom to top, and the end of the water supply pipe 2 inserted into the insertion hole 5.22 is provided with an upward-facing spray hole 2a, so that when water is received in the water supply pipe 2, water can be sprayed upward from the spray hole 2a to the top of the loading platform 5.2, so as to form a cup washing area above the loading platform 5.2 for placing cups a and washing the placed cups a.

[0061] At this time, when cup a is placed on the loading platform 5.2, cup a will exert a weight on the loading platform 5.2 downwards, forming pressure. The pressure is applied to the weighing sensor 5.1, causing the weighing sensor 5.1 to deform, thereby changing its impedance. At the same time, the excitation voltage changes, outputting a changing analog signal. This signal is amplified by the amplifier circuit of the main control unit and output to the analog-to-digital converter, where it is converted into a digital signal that is easy to process, thus forming the weighing value.

[0062] Meanwhile, a control valve 3 is also installed in the water supply pipeline 2 to control the opening / closing of the pipeline. Furthermore, a booster pump 4 is also installed in the water supply pipeline 2, configured to drive water in the pipeline 2 to spray out from the spray hole 2a. The control valve 3 is a solenoid valve commonly used in pipeline systems to control the opening / closing of pipes, while the booster pump 4 is a water pump commonly used in pipeline systems to pressurize the water in the pipeline and drive the pressurized water to be output in a specific direction. In this embodiment, the inlet of the booster pump 4 is connected to the inlet end of the water supply pipeline 2, and the outlet is connected to the spray hole 2a of the water supply pipeline 2. (See attached diagram) Figure 6 As shown, in this embodiment, the water control valve 3 can be installed in the part of the water supply pipe 2 located between the booster pump 4 and the spray hole 2a.

[0063] A main control device electrically connected to a power source is also provided. The weighing module, water control valve 3, and booster pump 4 are all electrically connected to the main control device. The main control device supplies power to the weighing module, and the weighing module transmits the obtained weighing value of the placed object to the main control device. The main control device supplies power to the water control valve 3 and controls the water control valve 3 to open so that the water supply pipeline 2 is unobstructed, or controls the water control valve 3 to open and close so that the water supply pipeline 2 is closed. The main control device supplies power to the booster pump 4 and controls the booster pump 4 to open so that the water in the water supply pipeline 2 is pressurized and sprayed out, or controls the booster pump 4 to close so that no pressure is applied to the water in the water supply pipeline 2.

[0064] Furthermore, the main control device is configured to: set a start threshold, compare the received weighing value with the start threshold, and when the weighing value is greater than or not greater than the start threshold, control the water control valve 3 and the booster pump 4 to open for cup cleaning / control the water control valve 3 and the booster pump 4 to close to end cup cleaning.

[0065] To be precise, the main control device is equipped with a start-up threshold, which can be zero or other set values.

[0066] When cup a is placed on the loading platform 5.2 with its opening facing downwards and opposite the spray hole 2a, the weighing module will acquire a weight value of cup a. This weight value is transmitted to the main control device, which compares the weight value with a start-up threshold (e.g., 0). When the weight value is greater than the start-up threshold (e.g., 0), it is determined that cup a is placed on the loading platform 5.2. The main control device controls the water control valve 3 to open and simultaneously controls the booster pump 4 to open, so that the water in the water supply pipe 2 is sprayed upwards to rinse the inside of cup a.

[0067] When cup a is removed, the weighing module obtains a weighing value of zero, which is not greater than the start threshold (e.g., 0). The main control device controls the water control valve 3 to close and simultaneously controls the booster pump 4 to close, thereby ending the cup cleaning process.

[0068] In the above scheme, the power of the booster pump 4 is set according to the actual rinsing needs to stably rinse the cup a. However, to adapt to rinsing cups a of different weights, the power of the booster pump 4 is often set relatively low, achieving cleaning while avoiding excessive rinsing pressure that could tip over the cup a. However, this method cannot effectively clean heavy cups more thoroughly.

[0069] Therefore, in this embodiment, the main control device can also be set with multiple limiting thresholds that are all greater than the start threshold and increase sequentially: A1, A2.......An, where n is a value greater than or equal to 2; the booster pump 4 is set with multiple power levels that gradually increase in match with the limiting thresholds: B1, B2.......Bn.

[0070] Meanwhile, the main control device is configured to compare the weighing value with a limit threshold, and when the weighing value reaches a certain limit threshold An, control the booster pump 4 to operate at the power corresponding to the Bn gear.

[0071] For example, the main control device has a start threshold of 0 and two limit thresholds, 20g and 100g. At the same time, the booster pump 4 is set with a minimum power level matching 0, a first power level matching 20g, and a second power level matching 100g, with the second power level being greater than the first power level.

[0072] When the weight of the cup a placed on the loading platform 5.2 is between 0 and 20g, the main control device controls the booster pump 4 to operate at the lowest power level.

[0073] When the weight of the cup a placed on the loading platform 5.2 is between 20g and 100g, the main control device controls the booster pump 4 to operate at the first power level.

[0074] When the weight of the cup a placed on the loading platform 5.2 is greater than 100g, the main control device controls the booster pump 4 to operate at the second power level.

[0075] The specific setting of the threshold and the power level of the booster pump 4 are set according to the actual cup cleaning needs, and will not be specified here.

[0076] In this way, for cups of different weights, the cleaning tank assembly can provide an optimized cleaning solution, improving the cleaning efficiency and effectiveness of the cups.

[0077] In the above scheme, the loading platform 5.2 is set to be no higher than the opening of the cup washing tank 1.2, so as to better prevent water in the cup washing tank 1.2 from splashing out.

[0078] Moreover, as attached Figure 2 As shown, the loading platform 5.2 can also be provided with a vertically penetrating drain hole 5.21, so that water on the loading platform 5.2 can flow downward into the cup washing tank 1.2, reducing the possibility of water accumulating on the loading platform 5.2 and causing scale that affects weighing.

[0079] At this point, to facilitate the directional drainage of water used for washing cups, a drain outlet connected to a water supply and drainage pipe is provided at the bottom of the main washing tank 1.1 or the bottom of the cup washing tank 1.2; and the cup washing tank 1.2 is connected to the main washing tank 1.1. In this way, only one drain outlet is needed to drain the water from both the main washing tank 1.1 and the cup washing tank 1.2.

[0080] In this embodiment, a support platform 1.21 is formed on the bottom wall of the cup washing tank 1.2; and the bottom wall of the cup washing tank 1.2 is higher than the bottom wall of the main cleaning tank 1.1. The bottom of the cup washing tank 1.2 is connected to the main cleaning tank 1.1, and the bottom of the main cleaning tank 1.1 has a main tank drain outlet 1.11 for draining water. As described above, this not only allows water in both the cup washing tank 1.2 and the main cleaning tank 1.1 to be discharged through the main tank drain outlet 1.11, but also eliminates the need for additional plates forming the support platform 1.21 and additional pipes to guide water from the cup washing tank 1.2 to the main cleaning tank 1.1, thus simplifying the structure and saving costs.

[0081] In any of the above schemes, the weighing sensor 5.1 can be placed in different ways.

[0082] For example, attached Figure 3 As shown, the load cell 5.1 can be placed on the outer ring of the insertion hole 5.22 and provide support for the loading platform 5.2. This also enables the aforementioned weighing function.

[0083] However, in this case, the washing area (the area above the insertion hole 5.22) used to clean cup a is not vertically aligned with the position of the load cell 5.1, but rather staggered. This means that the center of gravity of cup a when placed often cannot be vertically aligned with the position of the load cell 5.1, and most load cells 5.1 (such as column type, S-type, cantilever beam type) are designed to measure only axial vertical loads. If the item and the sensor are misaligned, the direction of force may deviate from the sensor's sensitive axis, generating lateral force or bending moment; this can easily lead to uneven load distribution (such as unilateral force), exceeding the linear operating range of the sensor, resulting in nonlinear errors, manifested as inconsistent measurement accuracy across different weight ranges, and poor weighing system accuracy.

[0084] Therefore, the weighing sensor 5.1 often needs to be aligned vertically with the cup washing area to improve the accuracy and stability of cup washing.

[0085] In some solutions, a vertical through-hole can be made in the load cell 5.1, and the water pipe 2 can be inserted into the load cell 5.1 to achieve vertical alignment between the load cell 5.1 and the cup washing area. However, most load cells 5.1 are cantilevered structures. If a vertical opening is made in the load cell 5.1, it is easy to cause excessive reduction in the structural strength of the load cell 5.1, weakening its support and greatly shortening its service life.

[0086] Based on this, different methods are used in this embodiment to achieve the vertical alignment of the weighing sensor 5.1 and the cup washing area.

[0087] For details, see attached. Figure 4 As shown, the water supply pipe 2 in this embodiment includes: a water tank 2.2 placed between the weighing sensor 5.1 and the loading platform 5.2, which has a hollow water cavity 2.21. It also includes: a water supply pipe 2.1 connected to the water cavity 2.21 to supply water into the water cavity 2.21, and a booster pump 4 disposed in the water supply pipe 2.1. Specifically, the inlet end of the water supply pipe 2.1 is connected to a tap water pipe, and the outlet end of the water supply pipe 2.1 is connected to the water cavity 2.21 so that water in the water supply pipe 2.1 can flow into the water cavity 2.21. The inlet of the booster pump 4 is connected to the inlet end of the water supply pipe 2.1, and the outlet of the booster pump 4 is connected to the water cavity 2.21 through the outlet end of the water supply pipe 2.1.

[0088] Furthermore, the top of the water tank 2.2 has a water spray section 2.22 that is inserted into the insertion hole 5.22 of the loading platform 5.2 from bottom to top. The water spray hole 2a is provided in the water spray section 2.22. The lower end of the water spray hole 2a is connected to the water chamber 2.21, and the upper end is open, so that the cup washing area for cleaning cups and the weighing sensor 5.1 are arranged vertically aligned.

[0089] As described above, the weighing sensor 5.1 and the cup washing area are arranged vertically to improve the accuracy and stability of cup a's washing process by enhancing the accuracy and stability of cup a's weighing detection, while avoiding the need for additional drilling on the weighing sensor 5.1 and ensuring the structural stability of the weighing sensor 5.1. At this time, the weighing sensor 5.1 is calibrated based on the presence of the water tank 2.2 (for example, the water tank 2.2 is considered part of the loading platform 5.2).

[0090] Furthermore, considering that some water will remain in the water chamber 2.21 after each cup cleaning, which can easily breed limescale and bacteria, and also negatively affect the accuracy of the next cup weighing. Therefore, as shown in the attached... Figure 4 As shown, the water tank 2.2 can also be connected to a drain pipe 2.23 that communicates with the water chamber 2.21 to drain the water in the water chamber 2.21. The drain pipe 2.23 is equipped with a drain control valve 2.25 (a solenoid valve commonly used in pipeline systems to control the opening / closing of pipelines) to control the opening / closing of the drain pipe 2.23. The drain control valve 2.25 is electrically connected to the main control device. The main control device supplies power to the drain control valve 2.25 and controls its opening and closing: During cup cleaning, the main control device controls the drain control valve 2.25 to close, so that the drain pipe 2.23 is closed and not draining, allowing water to be sprayed steadily from the spray hole 2a; when the cup cleaning is finished, the main control device controls the drain control valve 2.25 to open, so that the drain pipe 2.23 is in a smooth draining state, allowing the water remaining in the water chamber 2.21 to be discharged from the drain pipe 2.23, avoiding any adverse effect of the residual water on the weighing accuracy of cup a.

[0091] Furthermore, as shown in the appendix Figure 5As shown, in this embodiment, the water supply pipe 2.1 is connected to the side wall of the water inlet chamber 2.21, and the drain pipe 2.23 is connected to the bottom wall of the water inlet chamber 2.21. Furthermore, the bottom wall of the water inlet chamber 2.21 extends horizontally, or it extends at an angle and forms a guide slope to direct the water flow from the water inlet chamber 2.21 to the drain pipe 2.23. This allows for a more thorough and natural drainage of the water in the water inlet chamber 2.21 when the cup cleaning process ends, ensuring that the weighing benchmark for each cup a remains consistent, thereby improving the accuracy of each weighing of cup a. This, in turn, allows for more stable and accurate control of the cup cleaning process by opening and closing the cup cleaning assembly.

[0092] As attached Figure 6 As shown, an additional water inlet control valve 15 can be installed at the water inlet of the water supply pipe 2. This is a solenoid valve that controls the opening and closing of the water supply pipe 2. The water inlet control valve 15 is electrically connected to the main control device. The main control device supplies power to the water inlet control valve 15 and controls the opening and closing of the water inlet control valve 15. When cleaning cups as described above, the main control device controls the water inlet control valve 15 to open so that the water supply pipe 2 is unobstructed. When cleaning cups as described above ends, the main control device controls the water inlet control valve 15 to close so that the water supply pipe 2 is closed.

[0093] Example 2:

[0094] Based on Embodiment 1, considering that cup a is sometimes used to hold beverages such as coffee or tea, and rinsing with pure water often fails to achieve satisfactory rinsing results, this embodiment further includes a cleaning tank assembly capable of generating bubbly water to rinse the cup.

[0095] For details, see attached. Figure 7 As shown, this embodiment also includes a foaming device 6, which is connected to the water supply pipe 2 and configured to generate foamed water in the water supply pipe 2. Simultaneously, the foaming device 6 is electrically connected to the main control device, which supplies power to the foaming device 6 and controls its opening and closing. Specifically: when the weighing value exceeds the activation threshold as described above, the main control device controls the foaming device 6 to open and generate foamed water in the water supply pipe 2, so that the spray nozzle 2a of the water supply pipe 2 can spray bubbly water upwards to clean the cup a; when the weighing value does not exceed the activation threshold as described above, the main control device simultaneously controls the foaming device 6 to close and end the cup cleaning process.

[0096] In this embodiment, the foaming device 6 includes: an air inlet pipe 6.1 connected to the water supply pipe 2, the air inlet pipe 6.1 being provided with: an air inlet pump 6.2 for inputting external air into the air inlet pipe 6.1; and a foamer 6.3 disposed in the water supply pipe 2 and located in the portion of the water supply pipe 2 between the booster pump 4 and the spray nozzle 2a; preferably located in the portion of the water supply pipe 2 between the air inlet pipe 6.1 and the spray nozzle 2a.

[0097] The air pump 6.2 is electrically connected to the main control device, which supplies power to the air pump 6.2. The main control device controls the aerator 6 to turn on by controlling the air pump 6.2 to turn on, and controls the aerator 6 to turn off by controlling the air pump 6.2 to turn off.

[0098] Among them, the air pump 6.2 is a commonly used air pump structure in the pipeline system to input external air into the pipeline, while the aerator 6.3 is also a commonly used aerator structure in the pipeline system to mix water and gas in the pipeline to form bubble water.

[0099] When using sparkling water to clean cup A, due to the physical properties and surface tension of the bubbles, when they collide with impurities on the inner wall of cup A and burst, they can generate greater energy to better impact the impurities, causing them to detach and thus cleaning cup A more effectively to achieve the desired level of cleanliness.

[0100] Furthermore, a one-way valve 6.4 can be installed in the air intake pipe 6.1. This one-way valve 6.4 is located between the air intake pump 6.2 and the water supply pipe 2 and is configured to allow gas to flow only from the air intake pump 6.2 to the water supply pipe 2. This allows for a better and more stable introduction of external air into the water supply pipe 2 to form bubble water.

[0101] As attached Figure 7 As shown, in this embodiment, the aerator 6.3 is placed in the part of the water supply pipe 2 between the booster pump 4 and the water control valve 3.

[0102] Example 3:

[0103] Based on either Embodiment 1 or Embodiment 2, considering that tap water often contains many impurities, prolonged use can easily lead to problems such as clogging of the spray nozzle 2a and scale buildup. In particular, when forming aerated water, impurities in tap water can easily corrode the aerator 6.3, thus shortening its service life.

[0104] Based on this, in this embodiment, as shown in the appendix Figure 8As shown, a first filter element 7 may also be provided, disposed in the water supply pipe 2 to filter the water in the water supply pipe 2. The first filter element 7 mainly includes: a clean water channel connected to the water supply pipe 2 to supply water flow, and a filter membrane disposed in the clean water channel to filter the flowing water. The filter membrane can be configured differently according to requirements.

[0105] As attached Figure 8 As shown in the figure, the first filter element 7 in this embodiment is disposed in the part of the water supply pipe 2 between the water inlet and the booster pump 4, so as to filter the water flowing into the booster pump 4 and better avoid the impurities in the tap water from causing corrosion to the booster pump 4.

[0106] Furthermore, considering that cup a may not be used for cleaning every day, the first filter element 7 is only used as a water filtration structure when cup a is being cleaned. As a result, the overall product has a low cost-performance ratio and cannot fully utilize the performance of the water purification structure.

[0107] Therefore, as attached Figure 8 As shown, on the extension path of the water supply pipe 2, the booster pump 4 is placed between the filter element 7 and the spray hole 2a; the part of the water supply pipe 2 placed between the booster pump 4 and the spray hole 2a is connected to a purified water outlet pipe 8 connected to the water supply pipe 2, and the end of the purified water outlet pipe 8 is connected to a purified water faucet 9 for water supply and discharge; a first high-pressure switch 10 is also installed in the purified water outlet pipe 8, which is configured to detect the water pressure between it and the purified water faucet 9.

[0108] The first high-pressure switch 10 is electrically connected to the main control device, which supplies power to the first high-pressure switch 10. The main control device is also configured to receive the water pressure value detected by the first high-pressure switch 10 and control whether the water purifier faucet 9 dispenses water based on the water pressure value.

[0109] Specifically, when the water purifier faucet 9 is opened, the water path between the first high-pressure switch 10 and the water purifier faucet 9 is connected to the outside air, thereby reducing the water pressure in that part of the water path. The main control device has a preset water pressure value. When the water pressure value detected by the first high-pressure switch 10 and transmitted to the main control device is lower than the preset water pressure value, the main control device controls the booster pump 4 to open, and the water purifier faucet 9 outputs filtered water. When an inlet control valve 15 is provided, it is simultaneously controlled to open.

[0110] When the water purifier faucet 9 is closed, water accumulates in the water path between the first high-pressure switch 10 and the water purifier faucet 9, causing an increase in water pressure. The first high-pressure switch 10 detects and transmits a water pressure value to the water purification control module that is higher than the predetermined water pressure value. The water purification control module then controls the booster pump 4 to shut down, and the water purifier faucet 9 stops outputting filtered water. When an inlet control valve 15 is provided, it is simultaneously controlled to close.

[0111] Furthermore, the purified water outlet pipe 8 may also be equipped with a second filter element 11 for filtering the water in the purified water outlet pipe 8. The second filter element 11 can be a reverse osmosis filter element structure, which has a wastewater discharge pipe 11.1 for discharging wastewater. The wastewater discharge pipe 11.1 is equipped with a wastewater control valve 11.2 for controlling the opening and closing of the wastewater discharge pipe 11.1. The wastewater control valve 11.2 is electrically connected to a main control device that supplies power to it. When the purified water faucet 9 is opened, the main control device synchronously controls the wastewater control valve 11.2 to open.

[0112] Furthermore, as shown in the appendix Figure 8 As shown, in this embodiment, the portion of the purified water outlet pipe 8 located between the second filter element 11 and the purified water faucet 9 can also be connected to a return water pipe 12 that connects the purified water outlet pipe 8 to the water supply pipe 2; the return water pipe 12 is equipped with a return water check valve 13 that only allows water to flow from the purified water outlet pipe 8 to the water supply pipe 2. In this way, when the booster pump 4 is working and causes excessive water pressure in the second filter element 11, or when a system error causes the cups to be cleaned and the purified water faucet 9 to be closed, but the booster pump 4 continues to work, the return water pipe 12, the water supply pipe 2, and the purified water outlet pipe 8 form a circulating channel for one-way water supply, which can release the water pressure in the pipeline to a certain extent, reduce the pressure of excessive water pressure on the components in the pipeline (such as the second filter element 11), and provide a certain safe buffer time for the maintenance of the booster pump 4.

[0113] As attached Figure 8 As shown, the portion of the water supply pipe 2 located between the first filter element 7 and the booster pump 4 is connected to the return water pipe 12 to better form the directional circulation channel as described above.
