Description

Technical Field

[0001] This invention relates to the field of kitchen equipment technology, and more specifically to sink systems and sink cleaning methods. Background Technology

[0002] With social development and the continuous improvement of people's living standards, people are paying more and more attention to health and have higher and higher requirements for drinking water. As a result, household water purifiers have become increasingly popular. Currently, many water purifiers are integrated with sinks to form sink systems.

[0003] For sink systems, tap water is typically used to rinse the sink after use to prevent the accumulation of impurities and bacterial growth. However, tap water often contains impurities, especially in areas with poor water quality; simply using tap water to rinse the sink can easily lead to limescale buildup, particularly at the bottom of the sink. Therefore, after the initial tap water cleaning, a purified water faucet is used to deliver filtered water from a water purifier to the sink for a second rinse. This ensures a higher level of cleanliness and reduces the likelihood of limescale formation.

[0004] Simply using filtered purified water to clean the sink has significant limitations, especially when there are sticky or oily substances stuck to the sink, it often fails to achieve a satisfactory cleaning result. Summary of the Invention

[0005] One of the objectives of this invention is to address the shortcomings of the prior art by providing a sink system that can better clean the sink, thereby creating a sink with higher cleanliness.

[0006] The second objective of this invention is to provide a sink cleaning method that can better clean the sink and improve its cleanliness.

[0007] The technical solution of the present invention is as follows:

[0008] The sink system includes:

[0009] sink;

[0010] The water inlet pipe has a water inlet at one end and a water purifier faucet at the other end.

[0011] In the direction from the water inlet to the water purifier faucet, the water inlet pipeline is sequentially equipped with: a first filter element for filtering the water in the pipeline, and a booster pump for pressurizing the water in the pipeline and delivering it to the water purifier faucet; so as to appropriately divide the water inlet pipeline into: an inlet pipe, a delivery pipe, and an outlet pipe.

[0012] The outlet pipe is connected to a branch pipe, which guides the water in the outlet pipe to the water tank;

[0013] The diversion pipe is equipped with a second control valve that controls the opening / closing of the flow channel within the diversion pipe;

[0014] Furthermore, the water tank system also includes an aerator, which is configured to generate bubbly water in the distribution pipe.

[0015] As a further preferred embodiment, the foaming device includes:

[0016] An air intake device installed in the conveying pipe is configured to deliver outside air into the conveying pipe;

[0017] The mixing tank, located in the manifold, is configured to mix the air and water in the manifold to form a water-air mixture.

[0018] An aerator installed in a distributor is configured to generate bubbles in a water-air mixture to form bubbly water.

[0019] As a further preferred option, the outlet pipe is equipped with a first control valve that controls the opening / closing of the flow channel within the outlet pipe;

[0020] The first control valve divides the water outlet pipe into: a first water outlet pipe connected to the booster pump, and a second water outlet pipe connected to the water purifier faucet;

[0021] The branch pipe is connected to the first outlet pipe.

[0022] As a further preferred option, the second outlet pipe is equipped with a reverse osmosis filter element for reverse osmosis filtration of the water in the second outlet pipe.

[0023] As a further preferred embodiment, the second control valve is electrically connected to the booster pump, the first control valve, and the intake device to achieve:

[0024] When the second control valve opens, the booster pump and intake device start simultaneously, and the first control valve closes simultaneously.

[0025] As a further preferred option, the water outlet pipe is equipped with a high-pressure switch located near the water purifier faucet;

[0026] The high-pressure switch is configured to detect the water pressure between itself and the water purifier faucet;

[0027] Furthermore, the high-pressure switch is electrically connected to the booster pump, the first control valve, and the second control valve, so that the water tank system can be controlled to open / close the pure water production mode based on the water pressure value detected by the high-pressure switch.

[0028] As a further preferred option, the outlet pipe is also connected to a hot flow pipe, which guides the water in the outlet pipe to the water tank;

[0029] Furthermore, the heat flow pipe n is equipped with:

[0030] The fourth control valve p1 is configured to control the opening / closing of the hot flow tube n;

[0031] The heating element p6 is configured to heat the water in the heat flow tube n.

[0032] As a further preferred embodiment, the sink includes a tank body having an upward-facing cleaning tank.

[0033] A flow guide is fixed to the tank body, which is located above one side wall of the cleaning tank and has an upward-facing flow guide channel.

[0034] The end of the diversion pipe furthest from the outlet pipe is connected to the guide channel;

[0035] The guide channel has several guide holes on its wall, which are matched to one side wall of the cleaning tank to achieve the following:

[0036] The bubble water in the diversion pipe can flow from the guide hole to the side wall of the cleaning tank to clean the inner wall of the cleaning tank.

[0037] The sink cleaning method includes:

[0038] S1: Use hot water to clean the inner wall of the cleaning tank in the sink;

[0039] S2: After cleaning with hot water, use sparkling water to clean the inner wall of the cleaning tank;

[0040] S3: After cleaning with sparkling water, clean the inner wall of the tank with filtered pure water.

[0041] As a further preferred option, before S1, the inner wall of the cleaning tank is cleaned with bubble water.

[0042] The main beneficial effects of the above technical solution are as follows:

[0043] By incorporating a diversion pipe and an aerator, a sink system is created that generates bubble water to clean the sink. When using bubble water to clean the sink, due to the physical properties and surface tension of the bubbles, when they collide with and burst the adhering impurities on the inner wall of the sink, they generate significant energy to more effectively impact and dislodge the impurities, thus cleaning the sink more thoroughly and achieving satisfactory cleanliness.

[0044] Further or more detailed beneficial effects will be described in conjunction with specific embodiments in the detailed implementation. Attached Figure Description

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

[0056] Example 1:

[0057] The sink system includes sink a, as shown in the attached diagram. Figure 3 As shown, sink a is a component used to collect water and wash items; it is typically installed in the kitchen countertop.

[0058] In this embodiment, as shown in the appendix Figure 3 Appendix Figure 4 As shown, the water tank a mainly includes a tank body a1; the tank body a1 has an upward-facing cleaning tank a1.1, and the bottom of the cleaning tank a1.1 is provided with a water outlet a1.2 for the liquid in the cleaning tank a1.1 to flow out. In addition, the water outlet a1.2 is generally also provided with a valve to control the opening and closing of the water outlet a1.2, so as to control the water outlet a1.2 to keep it unobstructed or closed according to the cleaning needs.

[0059] The water tank a1 is usually also fixedly connected to a tap x for connecting to a water pipe so that tap water can be output to the cleaning tank a1.1.

[0060] Meanwhile, in order to use filtered pure water to clean the inner wall of water tank a, mainly the cleaning tank a1.1 of water tank a, and improve cleanliness, a water purification device is also provided in this embodiment.

[0061] For details, see attached. Figure 1 As shown in the figure, this embodiment also includes a water purifier faucet c and an inlet pipe for connecting to a tap water pipe to deliver water from the tap water pipe to the water purifier faucet c.

[0062] The water purifier faucet c is preferably fixed to the tank a1, and its outlet is set opposite to the cleaning tank a1.1, so that the filtered pure water output from the water purifier faucet c can flow into the cleaning tank a1.1 to clean the inner wall of the cleaning tank a1.1.

[0063] In the direction from the water inlet b1.1 to the water purifier faucet c, the water inlet pipe is sequentially equipped with: a first filter element d to filter the water in the pipe, and a booster pump e to pressurize the water filtered by the first filter element d and then deliver the pressurized water to the water purifier faucet c. By setting the first filter element d and the booster pump e, the water inlet pipe is appropriately divided into: an inlet pipe b1, a delivery pipe b2, and an outlet pipe b3.

[0064] At this time, the booster pump e is turned on to start working, and the water purifier faucet c is turned on at the same time, so that the water tank system can be controlled to enter the water production mode to produce pure water: that is, tap water flows into the inlet b1.1 at the end of the inlet pipe b1 and flows to the first filter element d for filtration. The filtered water flows from the first filter element d through the conveying pipe b2, the booster pump e, and the outlet pipe b3 in sequence, and finally flows to the water purifier faucet c and is discharged into the cleaning tank a1.1 to clean the inner wall of the cleaning tank a1.1.

[0065] Simply using filtered purified water to clean the sink has significant limitations, especially when there are sticky or oily substances stuck to the sink, it often fails to achieve a satisfactory cleaning result.

[0066] Based on this, in this embodiment, a diversion pipe f is also connected to the water outlet pipe b3, which guides the water in the water outlet pipe b3 to the water tank a. Specifically, one end of the diversion pipe f is connected to the water outlet pipe b3, and the other end is connected to the cleaning tank a1.1, so that the water in the water outlet pipe b3 can flow to the cleaning tank a1.1 through the diversion pipe f to clean the inner wall of the cleaning tank a1.1.

[0067] Meanwhile, the diversion pipe f is also equipped with a second control valve k to control the opening / closing of the flow channel inside the diversion pipe f; and the water tank system also includes an aerating device g, which is configured to form bubble water in the diversion pipe f.

[0068] For details, see attached. Figure 1 As shown, the foaming device g in this embodiment includes: an air inlet device g1 disposed in the conveying pipe b2, configured to: deliver external air into the conveying pipe b2; a mixing tank g2 disposed in the diversion pipe f, configured to: mix the air in the diversion pipe f with water to form a water-air mixture; and a bubbler g3 disposed in the diversion pipe f, configured to: generate bubbles in the water-air mixture to form bubble water.

[0069] The air intake device g1 includes an air intake pipe g1.1 connected to the delivery pipe b2, and an air intake pump g1.2 connected to the air intake pipe g1.1 for introducing external air into the air intake pipe g1.1. A first one-way valve g1.3 is installed in the air intake pipe g1.1, allowing only the material in the air intake pipe g1.1 to flow from the air intake pump g1.2 to the delivery pipe b2. By driving the air intake pump g1.2 to work, external air can enter the delivery pipe b2 and flow into the distribution pipe f. Then, the air and water are mixed by the mixing tank g2, and then a large number of microbubbles are generated by the aerator g3 to form sparkling water.

[0070] The aforementioned mixing tank g2 and aerator g3 are commonly used devices for generating microbubbles in water, so they will not be described in detail here.

[0071] By placing the air intake device g1 on the delivery pipe b2 instead of the water inlet pipe b1, the air input by the air intake device g1 is less likely to impact the first filter element d under the directional flow of water, ensuring that the first filter element d can always filter water more stably.

[0072] Moreover, in the above scheme, the gas is introduced into the filtered pure water to form sparkling water, which ensures that the water used to form sparkling water through the mixing tank g2 and the aerator g3 is relatively pure. This can better avoid the adverse effects of impurities in tap water on the formation of sparkling water, and can also better avoid the corrosion of the mixing tank g2 and the aerator g3 by impurities in tap water.

[0073] Meanwhile, by setting the air intake device g1 in the delivery pipe b2, air enters the delivery pipe b2 and mixes with the water in the delivery pipe b2. After mixing, the air is pressurized by the booster pump e and flows into the distribution pipe f, which promotes a more stable and uniform mixing of air and water, improves the efficiency and effect of bubble formation, and thus increases the bubble content in the bubble water to a certain extent, thereby improving the cleaning effect of the water tank as described below.

[0074] At this time, close the water faucet c and open the second control valve k (to ensure unobstructed flow in the diversion pipe f). This will control the water tank system to operate in bubble-making mode, producing bubble water, which will then be used to clean the inner wall of the cleaning tank a1.1. Specifically, tap water flows into the inlet b1.1 at the end of the inlet pipe b1 and flows to the first filter element d for filtration. The filtered water then flows from the first filter element d through the conveying pipe b2, the booster pump e, the outlet pipe b3, and the diversion pipe f. The aerating device g drives the water in the diversion pipe f to form bubble water (or microbubble water). The bubble water finally flows into the cleaning tank a1.1, thus achieving the goal of cleaning the inner wall of the cleaning tank a1.1 with bubble water.

[0075] When using sparkling water to clean the inner wall of cleaning tank a1.1, due to the physical properties and surface tension of the bubbles, when they collide with the adhering impurities on the inner wall of cleaning tank a1.1 and burst, they can generate greater energy to better impact the impurities, causing them to detach, thereby better cleaning the water tank to achieve satisfactory cleanliness requirements.

[0076] The first filter element d, the booster pump e, the second control valve k, and the aerating device g can be installed in any position according to actual needs.

[0077] In this embodiment, the first filter element d, the booster pump e, the second control valve k, and the aerating device g are all preferably connected to the tank body a1. The tank body a1 provides positioning support for the above components, eliminating the need for additional support structures and making the overall structure of the water tank system simpler.

[0078] Furthermore, considering that when sink a is installed on the kitchen countertop, there is often a need to place items under it, while the space behind it (referring to the side of the sink facing away from the user after installation) is often an unusable idle area.

[0079] Therefore, in this embodiment, the first filter element d, the booster pump e, the second control valve k, and the aerator g are all placed at the rear of the water tank a. This avoids encroaching on the lower space of the water tank a, facilitates the connection of the water pipes at the bottom of the water tank a, and ensures that after the water tank a is installed, space is reserved at the bottom for storing items, making it convenient to place items.

[0080] The first filter element d, the booster pump e, the second control valve k, and the aerating device g can be detachably fixed to the tank a1 by screws.

[0081] However, considering the protection of the aforementioned components, in this embodiment, as shown in the attached... Figure 3 To be continued Figure 5The tank a1 is connected to: a first housing s located at the rear of the tank a; a first filter element d, a booster pump e, a second control valve k and a foaming device g (the air intake device g1, air intake pump g1.2 and first check valve g1.3 of the foaming device g) are all fixed inside the first housing s, so as to be connected to the tank a1 through the first housing s.

[0082] For details, see attached. Figure 3 To be continued Figure 5 The water tank a has a connecting plate a1.3 extending laterally to the right at its rear. The connecting plate a1.3 is provided with a first mounting hole a1.31. The size of the first mounting hole a1.31 is adapted to the outer contour size of the first housing s so that the first housing s can be inserted from top to bottom.

[0083] Furthermore, the outer periphery of the upper end of the first housing s is provided with an outwardly protruding first support portion s1. There are at least two first support portions s1, respectively disposed on both sides of the first support portion s1. When the first housing s is inserted into the first mounting hole a1.31 from top to bottom, the first support portion s1 overlaps the connecting plate a1.3, so that the first housing s is positioned and mounted on the water tank a.

[0084] When it is necessary to disassemble the first housing s, the first housing s can be pulled upward to disengage it from the first mounting hole a1.31 for disassembly.

[0085] At this time, in order to facilitate the handling of the first housing s, a first lifting part s2 for gripping can be provided on the top of the first housing s. In this embodiment, the first lifting part s2 is an opening provided on the top of the first housing s, into which the maintenance personnel can insert their hands to grip the top of the first housing s.

[0086] To prevent water and other debris from corroding the first casing, as shown in the attached... Figure 1 and attached Figure 2 As shown, a first cover plate a3 can be detachably connected to the connecting plate a1.3 by means of screws or snap-fit ​​structures. The first cover plate a3 covers the first mounting hole a1.31 and the first housing s from top to bottom to form a protective layer.

[0087] Furthermore, the connecting plate a1.3 may also be provided with a first positioning groove a1.32 facing upwards, matching the first support part s1. When the first housing s is inserted into the first mounting hole a1.31 from top to bottom, the first support part s1 is fitted into the first positioning groove a1.32 to achieve positioning and locking of the first support part s1, avoiding unnecessary lateral movement of the first support part s1 and the first housing s.

[0088] Based on the above, in order to increase the bubble content by allowing more air to enter the split pipe f when bubble water is formed as described above, the air input by the air intake device g1 can enter the split pipe f.

[0089] As attached Figure 1 As shown in the figure, in this embodiment, the water outlet pipe b3 is provided with: a first control valve h that controls the opening / closing of the flow channel inside the water outlet pipe b3; the first control valve h divides the water outlet pipe b3 into: a first water outlet pipe b3.1 connected to the booster pump e, and a second water outlet pipe b3.2 connected to the water purifier faucet c; the diversion pipe f is connected to the first water outlet pipe b3.1.

[0090] Thus, when bubble water is formed as described above, it is only necessary to close the first control valve h (controlling the flow channel inside the outlet pipe b3). The air input by the air intake device g1 will not escape into the second outlet pipe b3.2, but will enter the diversion pipe f as much as possible to increase the bubble content.

[0091] In the above scheme, each component can be controlled manually as described above to make the water tank system operate in water production mode or bubble water production mode; however, this method is cumbersome to control.

[0092] In this embodiment, both the first control valve h and the second control valve k are preferably solenoid valves.

[0093] Furthermore, it is preferable to electrically connect the second control valve k to the booster pump e, the first control valve h, and the air intake device g1, so as to achieve the following: when the second control valve k is opened, the booster pump e and the air intake device g1 are opened simultaneously (the air intake pump g1.2 is opened), and the first control valve h is closed simultaneously.

[0094] At this time, by controlling the second control valve k to open, the water tank system can be put into bubble water production mode as described above, so as to output bubble water to clean the inner wall of the cleaning tank a1.1.

[0095] It can also be further configured via electrical connection to achieve the following: when the second control valve k is closed, the booster pump e and the air intake device g1 are closed simultaneously, and the first control valve h is opened simultaneously.

[0096] Based on the above, this embodiment also includes a high-pressure switch m located near the water faucet c in the water outlet pipe b3. The high-pressure switch m is configured to detect the water pressure between itself and the water faucet c.

[0097] Furthermore, the high-pressure switch m is electrically connected to the booster pump e, the first control valve h, and the second control valve k, so that the water tank system can be controlled to open / close the pure water production mode based on the water pressure value detected by the high-pressure switch m.

[0098] That is, when the water faucet c is opened, the water path between the water faucet c and the high-pressure switch m is connected to the outside air, thereby reducing the water pressure between the high-pressure switch m and the water faucet c. At the same time, the high-pressure switch m is set with a predetermined water pressure value. When the water pressure value detected by the high-pressure switch m is lower than the predetermined water pressure value, the following controls are activated: the first control valve h is opened to allow water flow, the second control valve k is closed to block water flow, and the booster pump e is activated to put the water tank system into a pure water production mode so that pure water can be output to clean the inner wall of the cleaning tank a1.1.

[0099] Of course, the high-pressure switch m can also be electrically connected to the air intake device g1. When the water pressure value detected by the high-pressure switch m is lower than the predetermined water pressure value, the air intake device g1 is synchronously controlled to close.

[0100] When the water purifier faucet c is closed, water accumulates in the water path between the faucet c and the high-pressure switch m, causing an increase in water pressure. The high-pressure switch m detects a water pressure value higher than the predetermined value, thus controlling the first control valve h and the second control valve k to close and block water flow. At the same time, it controls the booster pump e to shut down, causing the water tank system to stop its water production mode.

[0101] The high-pressure switch m is preferably a single-phase high-pressure switch that only allows water to flow from the first control valve h to the water faucet c.

[0102] When actually cleaning water tank a, first turn on the bubble water mode to drive impurities off the surface of water tank a; then turn off the bubble water mode and turn on the pure water mode to rinse away the impurities and residual bubbles to achieve satisfactory cleanliness.

[0103] Furthermore, to improve the purity of the purified water, multiple filter cartridges can be installed in the water inlet pipe.

[0104] For example, attached Figure 2 As shown in the figure, this embodiment may also include: a reverse osmosis filter element j for reverse osmosis filtration of water in the inlet pipe, the reverse osmosis filter element j having a wastewater pipe j1 for wastewater discharge, the wastewater pipe j1 being provided with a third control valve j2 for controlling its opening / closing, the third control valve j2 being controlled according to the wastewater discharge requirements.

[0105] In this embodiment, considering that the internal structure of the reverse osmosis filter element j is more susceptible to damage from impacts, the reverse osmosis filter element j is preferably located at the second outlet pipe b3.2. This way, when bubble water is formed as described above and the first control valve h is closed, the gas entering the inlet pipe will not affect the reverse osmosis filter element j. Furthermore, when producing pure water as described above, the air pump g1.2 is closed, preventing the formation of excessive gas that could impact the reverse osmosis filter element j.

[0106] In addition, the second water outlet pipe b3.2 can also be equipped with a second filter element y to filter the water in the inlet pipe. The second filter element y is located between the water purifier faucet c and the reverse osmosis filter element j.

[0107] Furthermore, the first filter element d can be disposed together with the second filter element y in a housing to form a composite filter element structure.

[0108] Based on the above, the conveying pipe b2 can also be equipped with a water inlet control valve z that controls the opening and closing of the flow channel inside the conveying pipe b2. This water inlet control valve z is preferably electrically connected to the second control valve k and the high-pressure switch m. Whether producing pure water or sparkling water as described above, the water inlet control valve z is always in the open state for water supply.

[0109] Example 2:

[0110] In addition to the first embodiment, a heating device is provided in this embodiment to achieve a better cleaning effect.

[0111] In this embodiment, as shown in the appendix Figure 2 As shown, the water outlet pipe b3 is also connected to a hot water pipe n, which guides the water in the water outlet pipe b3 to the water tank a. Specifically, in this embodiment, one end of the water outlet pipe b3 is connected to the water outlet pipe b3, and the other end is connected to the cleaning tank a1.1.

[0112] Furthermore, a heating device is installed in the hot flow pipe n to heat the water in the hot flow pipe n. In this way, as described in Example 4 below, hot purified water, purified water, and sparkling water can be combined to better clean the water tank a.

[0113] For details, see attached. Figure 2 As shown, in this embodiment, in the extension direction from the outlet pipe b3 to the water tank a, the hot flow pipe n is equipped with: a fourth control valve p1 for controlling the opening / closing of the hot flow pipe n, a preheating tank p2 for storing water, a pump p3 for driving the water in the hot flow pipe n to flow to the water tank a, a second one-way valve p4 that only allows the water in the hot flow pipe n to flow to the water tank a, a flow meter p5 for monitoring the flow rate of the water in the hot flow pipe n, and a heating element p6 (e.g., an electric heating wire) for heating the water in the hot flow pipe n.

[0114] At this point, by controlling the booster pump e, the water inlet control valve z, the first control valve h, the fourth control valve p1, the liquid pump p3, and the heating element p6 to open, and controlling the second control valve k to close, high-temperature pure water can be output to the cleaning tank a1.1.

[0115] Of course, referring to the control method in Embodiment 1, the fourth control valve p1 is preferably a solenoid valve, and can be electrically connected to the booster pump e, the water inlet control valve z, the first control valve h, the liquid pump p3, the heating element p6, and the second control valve k.

[0116] Achieve the following: Open the fourth control valve p1, which controls the booster pump e, the water inlet control valve z, the first control valve h, the liquid pump p3, and the heating element p6 to start; control the second control valve k to close. Produce hot purified water and output high-temperature purified water to the cleaning tank a1.1.

[0117] Closing the fourth control valve p1 means that the booster pump e, the water inlet control valve z, the first control valve h, the liquid pump p3, the heating element p6, and the second control valve k are all closed.

[0118] In actual use, the pure water production mode, hot water production mode, and sparkling water production mode should not be activated simultaneously.

[0119] Preferably, the preheating tank p2 can also be equipped with a heating structure, such as an electric heating rod, to preheat the water entering the preheating tank p2, thereby improving heating efficiency.

[0120] Furthermore, the hot water pipe n can be connected to a first branch pipe p8 and a second branch pipe p9 via a water distribution valve p7. The second branch pipe p9 is connected to the cleaning tank a1.1 to deliver water from the hot water pipe n to the cleaning tank a1.1. The first branch pipe p8 can be connected to a new faucet to meet the demand for hot purified water. Alternatively, the water faucet c is preferably a hot and cold water faucet, with the first branch pipe p8 connected to the hot water inlet and the outlet pipe b3 connected to the cold water inlet.

[0121] Furthermore, referring to the filter element connection structure in Embodiment 1, the fourth control valve p1, preheating tank p2, liquid pump p3, second check valve p4, flow meter p5, and heating element p6 are all preferably fixed inside the second housing t, and connected to the tank a1 through the second housing t. The second housing t is connected to the tank a1 and is located at the rear of the water tank a.

[0122] The specific connection structure of the second housing t on the tank a1 is similar to that of the first housing s, and will not be described in detail here.

[0123] Example 3:

[0124] Based on Embodiment 1 or Embodiment 2, this embodiment adds a guide member a2 for cleaning the side wall of the cleaning tank a1.1, so that the bubble water can better brush along the inner wall of the cleaning tank a1.1 to improve the cleaning effect.

[0125] For details, see attached. Figure 6 To be continued Figure 9 As shown, in this embodiment, a guide member a2 is fixedly connected to the tank a1. The guide member a2 is located above one side wall of the cleaning tank a1.1 and has an upward-facing guide groove a2.1.

[0126] Meanwhile, the end of the diversion pipe f that is away from the outlet pipe b3 is connected to the guide channel a2.1.

[0127] Furthermore, the wall of the guide channel a2.1 has a number of guide holes a2.2, which are matched to one side wall of the cleaning tank a1.1 to achieve the following: when there is liquid (e.g., water) in the guide channel a2.1, the liquid (e.g., water) can flow from the guide holes a2.2 to one side wall of the cleaning tank a1.1, preferably to the upper end of one side wall of the cleaning tank a1.1, so as to clean the side wall.

[0128] At this time, as described above, after the tap water enters the guide channel a2.1 from the inlet pipe a3, the water in the guide channel a2.1 will flow from several guide holes a2.2 to one side wall of the cleaning tank a1.1 (as shown in the attached diagram). Figure 8 (As shown by the dashed arrow in the middle), this process cleans one side wall of the cleaning tank a1.1 to keep the side wall clean and reduce the possibility of bacterial accumulation and growth.

[0129] The flow guide channel a2.1 has a side wall and a bottom wall a2.11 located at the bottom. Depending on the placement of the flow guide a2, the flow guide hole a2.2 can be set on the side wall or the bottom wall a2.11 of the flow guide channel a2.1.

[0130] In this embodiment, to ensure that the water flows downwards from the guide hole a2.2 to the side wall of the cleaning tank a1.1 for better rinsing of the side wall, as shown in the attached diagram. Figure 2 and attached Figure 3 As shown, the bottom wall a2.11 of the tank has a portion that is suspended and located above one side wall of the cleaning tank a1.1, and a plurality of guide holes a2.2 are provided in this portion.

[0131] Achievement: When water flows down from the guide hole a2.2, it can impact and fall onto one side wall of the cleaning tank a1.1, so as to better flush the side wall from top to bottom and improve the cleaning effect.

[0132] At this point, a downwardly protruding baffle a2.3 can also be provided at the bottom of the suspended part of the guide member a2, located on one side of the guide hole a2.2, to block the liquid flowing out of the guide hole a2.2 laterally. In this way, the baffle a2.3 can prevent the water flowing down from the guide hole a2.2 from flowing laterally, avoiding lateral splashing of water, and allowing more water to concentrate on flowing downwards onto the side wall of the cleaning tank a1.1, improving the cleaning effect while minimizing water waste.

[0133] Based on the above, in order to prevent impurities from falling into the guide channel a2.1, a cover plate a4 can be fixed to the guide component a2, which covers the opening of the guide channel a2.1 from top to bottom.

[0134] The cover plate a4 can be fixed to the guide member a2 by a non-removable connection method such as welding; or the cover plate a4 can be integrated with the guide member a2.

[0135] In this embodiment, in order to enable regular maintenance and cleaning of the flow guide channel a2.1, the cover plate a4 is preferably detachably fixed to the flow guide a2. For example, the cover plate a4 can be detachably fixed to the flow guide a2 by screws; or, as shown in the attached... Figure 3 As shown, the lower end of the cover plate a4 has a protrusion that is adapted to be fitted into the flow guide groove a2.1. By adapting and fitting the protrusion into the flow guide groove a2.1, the cover plate a4 is detachably fixed to the flow guide a2.

[0136] Furthermore, as shown in the appendix Figure 1 As shown, the tank a1 may also be provided with a positioning slot a1.3 located above one side wall of the cleaning tank a1.1; the size of the positioning slot a1.3 is adapted to the outer contour size of the guide component a2, and the guide component a2 is fitted into the positioning slot a1.3 to achieve more stable positioning.

[0137] The specific structure of the positioning slot a1.3 is set according to the size and structure of the guide component a2.

[0138] As attached Figure 3 As shown, when the bottom wall a2.11 of the tank has a portion that is suspended and located above one side wall of the cleaning tank a1.1, and a plurality of guide holes a2.2 are provided in this portion, the guide member a2 is preferably partially embedded in the positioning slot a1.3. At this time, a downwardly protruding baffle a2.3 is provided at the bottom of the suspended portion of the guide member a2, and the baffle a2.3 is located on the side of the guide hole a2.2 away from the positioning slot a1.3.

[0139] Furthermore, in order to better position the flow guide a2, a plug-in positioning structure can also be provided between the flow guide a2 and the tank a1.

[0140] For example, attached Figure 3 As shown, when the upper end of the positioning slot a1.3 is open, the lower end of the guide a2 can be provided with a downwardly protruding insertion part a2.4, and the bottom of the positioning slot a1.3 can be provided with an insertion hole a1.31 that matches the insertion part a2.4. This achieves the following: when the guide a2 is installed from top to bottom in the positioning slot a1.3, the insertion part a2.4 is adapted to be inserted downwards into the insertion hole a1.31, thereby achieving stable positioning of the guide a2 on the tank a1.

[0141] For the cleaning tank a1.1, it generally has multiple adjacent side walls. In order to better clean each side wall, a guide a2 can be matched and installed above each side wall of the cleaning tank a1.1.

[0142] For example, attached Figure 6 Appendix Figure 7 As shown, the cleaning tank a1.1 is generally a square tank, therefore, it has four side walls: top, bottom, left, and right. A guide a2 can be matched above each of the top, bottom, left, and right side walls to clean each side wall.

[0143] Meanwhile, the several guide components a2 are preferably arranged end to end to form a ring structure, which makes the overall structure composed of several guide components a2 have higher strength and facilitates the overall transportation and installation.

[0144] Based on the above, considering that each guide member a2 has a guide groove a2.1, if each guide member a2 is equipped with a water inlet pipe a3, the pipeline connection would be complicated. Therefore, in this embodiment, any two adjacent guide grooves a2.1 are preferably connected to each other so that all guide grooves a2.1 are interconnected; and only one guide member a2 is equipped with a water inlet pipe a3. In this way, it is only necessary to connect the water inlet pipe a3 to the outlet pipe of a tap or faucet, and the water from the tap or faucet can flow into each guide groove a2.1 through the water inlet pipe a3, thereby cleaning each side wall of the cleaning tank a1.1.

[0145] Example 4:

[0146] The sink cleaning method includes:

[0147] S1: Use hot water to clean the inner wall of the cleaning tank a1.1 in the water tank a; the specific temperature of the hot water is set according to the needs, generally greater than 90 degrees.

[0148] S2: After cleaning with hot water, use bubble water to clean the inner wall of cleaning tank a1.1;

[0149] S3: After cleaning with bubble water, clean the inner wall of tank a1.1 with filtered pure water.

[0150] In this way, hot water is first used to soften the adhering impurities on the inner wall of cleaning tank a1.1; then, when sparkling water is used to clean the inner wall of cleaning tank a1.1, due to the physical properties and surface tension of the bubbles, when they collide with the adhering impurities on the inner wall of the tank and burst, they can generate greater energy to better impact the impurities and remove them; then, purified water is used to clean the inner wall of cleaning tank a1.1 to wash away the impurities and residual bubbles, so as to achieve satisfactory cleanliness requirements.

[0151] Before step S1, it is preferable to first use sparkling water to clean the inner wall of the cleaning tank a1.1. This first uses sparkling water to impact the adhering impurities on the inner wall of the tank, allowing some of the adhering impurities to detach from the inner wall of the cleaning tank a1.1. Then, hot water is used for cleaning, which can better soften or remove the adhering impurities, thereby further improving the cleaning effect.
