Description

Technical Field

[0001] This utility model relates to the technical field of kitchen cleaning equipment, and more specifically to sink equipment. Background Technology

[0002] With the improvement of living standards and the enhancement of health awareness, consumers have placed higher demands on the cleanliness of domestic water, leading to a growing demand for integrated water treatment devices. To address this, existing technologies have developed composite water tank devices that integrate a water purification unit with a water tank structure, achieving drinking water purification through multi-stage filtration modules.

[0003] In existing technical solutions, this sink device primarily utilizes two water sources to create two different self-cleaning structures: one is the direct use of untreated municipal water, and the other is the recycling of purified water that has undergone primary filtration for rinsing. However, long-term usage observations show that in the high-temperature, high-fume environment of a kitchen, these two self-cleaning structures often fail to achieve satisfactory cleaning results. During long-term use in a kitchen, this sink device is prone to complex pollution problems such as microbial growth and grease buildup. Stubborn stains, especially those forming on the sink's inner walls, drain outlets, and pipe connections, are more likely to pose hygiene and safety hazards, severely impacting the user experience.

[0019] As a further preferred option, the outer periphery of the drainage tube is fitted with a first heating element for heating.

[0020] As a further preferred embodiment, the first heating element is clamped between the drain pipe and the tank body, so that: the two sides of the first heating element are respectively in contact with the drain pipe and the tank body.

[0021] As a further preferred embodiment, the water purification unit includes a filter group that filters the incoming water and delivers the filtered water to the first outlet pipe.

[0022] The first outlet water pipe has a section located between the steam generator and the filter assembly, and the first control valve is located in this section.

[0023] As a further preferred embodiment, the first outlet pipe has a portion located between the first control valve and the filter assembly, and this portion is connected to the second outlet pipe;

[0024] The end of the second water outlet pipe that is furthest from the first water outlet pipe is connected to the first water outlet faucet.

[0025] As a further preferred embodiment, the water purification unit includes: an inlet pipe for supplying water in and conveying the inflowing water into the filter assembly;

[0026] The inlet pipe is equipped with a second control valve that controls the opening and closing of the inlet pipe;

[0027] The second water outlet pipe is equipped with a first high-pressure switch, which is configured to detect the water pressure between it and the first water outlet tap.

This allows high-temperature steam to be directed into the cleaning tank by turning on the water purification unit and the steam generator, so as to better clean the oil stains in the cleaning tank, improve the cleanliness of the water tank, and provide a better user experience.

[0037] Moreover, using filtered water as the water source for the steam generator can better prevent impurities in tap water from adversely affecting the steam generator and improve its long-term service life.

[0038] Meanwhile, by setting the bottom wall of the drainage pipe at an angle, the condensate formed by the condensation of steam in the drainage pipe can be guided to a low-lying area, thereby better reducing the impact on steam flow.

[0039] Further or more detailed beneficial effects will be described in conjunction with specific embodiments in the detailed implementation. Attached Figure Description

[0040] The present invention will be further described below with reference to the accompanying drawings:

[0045] Figure 5 A schematic diagram of the overall pipeline structure for setting up multiple water taps. Detailed Implementation

[0046] The present invention will be illustrated with specific examples below:

[0047] Example 1:

[0048] The water tank equipment includes a water tank 1; wherein, the water tank 1 includes a tank body 1.1 made of multiple metal materials, as shown in the attached figure. Figure 1 As shown, the tank 1.1 has an upward-facing cleaning tank 1.11, and also includes a drain pipe 1.2 connected to the tank 1.1 and used to drain the liquid from the cleaning tank 1.11. Specifically, the bottom wall of the cleaning tank 1.11 is provided with an outlet for draining the liquid from the cleaning tank 1.11. The upper end of the drain pipe 1.2 is connected to the outlet, and the lower end is generally connected to the building's sewage pipe, so that the liquid in the cleaning tank 1.11 can be discharged from the drain pipe 1.2 and discharged into the building's sewage pipe.

[0049] The tank body 1.1 is generally also equipped with a tap faucet 1.3 for delivering tap water to the cleaning tank 1.11.

[0050] After use (e.g., washing items in the washing tank 1.11), tap water is supplied to the washing tank 1.11 via the tap 1.3 to rinse the sink 1, especially the washing tank 1.11, to prevent the accumulation of impurities and the growth of bacteria. However, when the sink 1 is used in the kitchen for a long time, it is found that in the kitchen's oily and fume-filled working environment, the sink 1 often accumulates a lot of grease due to direct adhesion of grease or washing of oily items. Simply using tap water is often insufficient to clean the grease-covered sink 1 effectively. As a result, after prolonged use, the sink 1, especially the washing tank 1.11, is prone to grease buildup, which seriously affects the user experience.

[0051] Therefore, in order to better clean oil stains, a steam generator 3 is preferably used in this embodiment. By converting tap water into steam and transporting it to the cleaning tank 1.11, the above problems can be solved by better cleaning oil stains.

[0052] However, in actual use, it was found that tap water often contains a lot of impurities. Directly supplying tap water to the steam generator 3 to convert it into steam can easily have a negative impact on the steam generator 3. This not only affects the steam generation effect but also easily damages the steam generator 3 and reduces its service life.

[0053] Based on this, this embodiment is provided with a water purification unit that supplies water in and filters the inflowing water, and a steam generator 3 and corresponding pipelines are provided according to the water purification unit, so as to better clean the oil stains in the cleaning tank 1.11 while reducing the impact on the steam generator 3, so that the steam generator 3 has a longer service life.

[0054] Specific details are attached. Figure 2 As shown, this embodiment is provided with a water purification unit that supplies water in and filters the inflowing water. It includes a filter group 2.1 that filters the inflowing water and delivers the filtered water to the first outlet pipe 2.3, and an inlet pipe 2.2 that supplies water in and delivers the inflowing water into the filter group 2.1.

[0055] To be precise, as shown in the appendix Figure 2 As shown, the filter assembly 2.1 in this embodiment includes a water supply pipe 2.1a for water flow, with a filter inlet at one end for water to flow into the water supply pipe 2.1a and a filter outlet at the other end for water to flow out of the water supply pipe 2.1a; and the water supply pipe 2.1a is provided with at least a first water purification filter element 2.1b for filtering the water flowing into the water supply pipe 2.1a. The first water purification filter element 2.1b mainly includes: a water purification channel connected to the water supply pipe 2.1a for water to flow through, and a filter membrane disposed in the water purification channel for filtering the flowing water.

[0056] One end of the inlet pipe 2.2 is connected to the tap water pipe, and the other end is connected to the filter inlet of the water supply pipe 2.1a, so that tap water can enter the filter group 2.1 from the inlet pipe 2.2 for filtration. At the same time, the water purification unit is connected to the first outlet pipe 2.3 for the filtered water to flow out; that is, the filter outlet of the water supply pipe 2.1a is connected to the first outlet pipe 2.3, so that the water filtered by the filter group 2.1 can be discharged from the first outlet pipe 2.3.

[0057] To improve filtration efficiency, see attached... Figure 2As shown, other filter structures can also be installed in the water supply pipe 2.1a, such as a second water purification filter 2.1g (the second water purification filter 2.1g mainly includes: a water purification channel connected to the water supply pipe 2.1a for water to flow through, and a filter membrane installed in the water purification channel for filtering the flowing water, and the filter membrane of the second water purification filter 2.1g and the filter membrane of the first water purification filter 2.1b can be configured differently according to requirements).

[0058] Furthermore, the outlet end of the first water outlet pipe 2.3 (i.e. the end of the first water outlet pipe 2.3 away from the filter group 2.1) is connected to the cleaning tank 1.11 so that the fluid in the first water outlet pipe 2.3 can be input into the cleaning tank 1.11; and the first water outlet pipe 2.3 is provided with: a steam generator 3 that converts water into steam and delivers steam to the cleaning tank 1.11, and a first control valve 2.12 that controls the opening / closing of the first water outlet pipe 2.3 (by controlling the opening / closing of the first control valve 2.12, the opening / closing of the first water outlet pipe 2.3 is controlled).

[0059] When the water tank equipment is actually installed and used, the end of the water inlet pipe 2.2 furthest from the filter group 2.1 is connected to the tap water pipe. When steam cleaning of the cleaning tank 1.11 is required:

[0060] By opening the first control valve 2.12 to ensure the first outlet pipe 2.3 is unobstructed, the steam generator 3 is connected to the power supply and turned on. Tap water then enters the filter group 2.1 through the inlet pipe 2.2 for filtration to form filtered water. This filtered water flows into the steam generator 3 through a portion of the first outlet pipe 2.3, where it is converted into steam. The steam then flows into the cleaning tank 1.11 through another portion of the first outlet pipe 2.3 to perform steam cleaning on the inner wall of the cleaning tank 1.11.

[0061] Closing the first control valve 2.12 to close the first water outlet pipe 2.3 and shutting off the steam generator 3 will shut down the steam cleaning process.

[0062] The aforementioned water tank equipment, which can use steam to clean the cleaning tank 1.11, can not only directionally discharge high-temperature steam into the cleaning tank 1.11 to better clean the oil stains in the cleaning tank 1.11 and improve the cleanliness of the water tank 1, but also provide a better user experience.

[0063] Moreover, the above scheme uses filtered water as the water source for the steam generator 3, which can better prevent impurities in tap water from having a negative impact on the steam generator 3 and improve the long-term service life of the steam generator 3.

[0064] In the above scheme, the first control valve 2.12 and the steam generator 3 can be directly controlled manually to achieve the above steam cleaning steps, but the operation is relatively cumbersome.

[0065] For ease of operation, in this embodiment, a water purification control module for electrical connection to a power source is preferably provided in the water purification unit. The steam generator 3 is electrically connected to this water purification control module, which supplies power to the steam generator 3 and controls its on / off switching. The first control valve 2.12 is a solenoid valve that controls the opening / closing of the first water outlet pipe 2.3. It is electrically connected to the water purification control module, which controls the opening / closing of the first control valve 2.12 to control the opening / closing of the first water outlet pipe 2.3.

[0066] Meanwhile, a switch structure electrically connected to the water purification control module is also provided. This switch structure is configured to: control the steam generator 3 and the first control valve 2.12 to open synchronously, so as to generate steam to clean the cleaning tank 1.11 as described above; and also control the steam generator 3 and the first control valve 2.12 to close synchronously.

[0067] In one embodiment, the switch structure may include a cleaning start button and a cleaning stop button disposed on the water tank 1 or the water purification unit. The cleaning start button is configured to be electrically connected to the water purification control module and to control the steam generator 3 and the first control valve 2.12 to open synchronously; the cleaning stop button is configured to be electrically connected to the water purification control module and to control the steam generator 3 and the first control valve 2.12 to close synchronously.

[0068] Based on the above scheme, the water supply pipeline 2.1a can also be equipped with: a booster pump 2.1f that pressurizes the water in the pipeline and delivers the pressurized water to the first outlet pipeline 2.3; and a reverse osmosis filter element 2.1c that receives the water output from the booster pump 2.1f, performs reverse osmosis filtration on the water, and then delivers it to the first outlet pipeline 2.3. The reverse osmosis filter element 2.1c has a wastewater pipe 2.1d that discharges wastewater from the filtration process. This wastewater pipe is equipped with a wastewater control valve 2.1e to control its opening / closing (by controlling the opening / closing of the wastewater control valve 2.1e, the opening / closing of the wastewater pipe 2.1d is controlled). When steam cleaning is required as described above, the booster pump 2.1f and the wastewater control valve 2.1e are turned on to produce filtered water.

[0069] When the water purification unit is equipped with a water purification control module, the booster pump 2.1f is electrically connected to the water purification control module. The water purification control module supplies power to the booster pump 2.1f and controls the booster pump 2.1f to open and close. The wastewater control valve 2.1e is a solenoid valve that controls the opening and closing of the wastewater pipe 2.1d. It is electrically connected to the water purification control module. The water purification control module controls the opening and closing of the wastewater pipe 2.1d by controlling the opening and closing of the wastewater control valve 2.1e.

[0070] At this time, the switch structure is configured to: control the steam generator 3, the first control valve 2.12, the booster pump 2.1f, and the wastewater control valve 2.1e to open synchronously, so as to generate steam to clean the cleaning tank 1.11 as described above; and also control the steam generator 3, the first control valve 2.12, the third control valve 7.2, the booster pump 2.1f, and the wastewater control valve 2.1e to close synchronously. For example, the cleaning start button is configured to: be electrically connected to the water purification control module and control the steam generator 3, the first control valve 2.12, the booster pump 2.1f, and the wastewater control valve 2.1e to open synchronously; the cleaning stop button is configured to: be electrically connected to the water purification control module and control the steam generator 3, the first control valve 2.12, the booster pump 2.1f, and the wastewater control valve 2.1e to close synchronously.

[0071] In some embodiments, the water inlet pipe 2.2 may also be provided with a second control valve 2.6 to control the opening / closing of the water inlet pipe 2.2 (by controlling the opening / closing of the second control valve 2.6, the water inlet pipe 2.2 is controlled to open / close). This controls whether water enters the water purification unit.

[0072] When the water purification unit is equipped with a water purification control module, the second control valve 2.6 is a solenoid valve that controls the opening / closing of the inlet pipe 2.2. It is electrically connected to the water purification control module, which controls the opening / closing of the wastewater control valve 2.1e to control the opening / closing of the inlet pipe 2.2. The switching structure is configured to: control the second control valve 2.6, steam generator 3, first control valve 2.12, booster pump 2.1f, and wastewater control valve 2.1e to open synchronously, so as to generate steam to clean the cleaning tank 1.11 as described above; it can also control the second control valve 2.6, steam generator 3, first control valve 2.12, third control valve 7.2, booster pump 2.1f, and wastewater control valve 2.1e to close synchronously. For example, the cleaning start button is configured to be electrically connected to the water purification control module and to control the second control valve 2.6, steam generator 3, first control valve 2.12, booster pump 2.1f, and wastewater control valve 2.1e to open synchronously; the cleaning stop button is configured to be electrically connected to the water purification control module and to control the second control valve 2.6, steam generator 3, first control valve 2.12, booster pump 2.1f, and wastewater control valve 2.1e to close synchronously.

[0073] Furthermore, the outlet end of the first water outlet pipe 2.3 can be directly inserted into the cleaning tank 1.11 from the slot opening to deliver steam to the cleaning tank 1.11 during steam cleaning. However, this may interfere with the cleaning space of the cleaning tank 1.11 and affect the normal cleaning operation.

[0074] Based on this, in this embodiment, as shown in the appendix Figure 3 To be continued Figure 4 As shown, the tank 1.1 of this embodiment is provided with a steam inlet 1.12 located on the side wall of the cleaning tank 1.11; the steam inlet 1.12 is a through hole structure provided on the side wall of the cleaning tank 1.11, so that fluid outside the cleaning tank 1.11 can flow into the cleaning tank 1.11 from the steam inlet 1.12.

[0075] Meanwhile, a drainage pipe 8 is also provided on the outer periphery of the tank 1.1, located outside the cleaning tank 1.11. The drainage pipe 8 has a hollow cavity 8.1 inside, and its wall has an inlet 8.2 for connecting the drainage cavity 8.1 to the external space of the drainage pipe 8, and an outlet 8.3 for connecting the drainage cavity 8.1 to the external space of the drainage pipe 8. The outlet end of the first water outlet pipe 2.3 is connected to the inlet 8.2, and the outlet 8.3 is connected to the steam inlet 1.12. This allows the steam in the first water outlet pipe 2.3 to enter the drainage cavity 8.1 of the drainage pipe 8 through the inlet 8.2 after steam is generated as described above, and then flow from the outlet 8.3 to the steam inlet 1.12, and finally from the steam inlet 1.12 into the cleaning tank 1.11, thus performing steam cleaning of the cleaning tank 1.11.

[0076] In the above scheme, the extension path and length of the diversion pipe 8 are set according to the arrangement position of the steam inlet 1.12, which in turn is set according to the cleaning requirements. In order to clean more areas, the diversion pipe 8 often needs to be set relatively long, which makes it easy for steam to condense in the diversion chamber 8.1, resulting in a lot of condensate in the diversion chamber 8.1. This, in turn, makes it easy for scale to accumulate in the diversion chamber 8.1, which hinders the smooth flow of steam and reduces cleaning efficiency.

[0077] At this point, the condensate appearing in the drainage chamber 8.1 can be diverted and collected in a low-lying area inside the drainage chamber 8.1 to reduce its impact on steam flow.

[0078] Specifically, the inner wall of the drainage pipe 8 (i.e., the cavity wall surrounding the drainage chamber 8.1) includes a bottom wall at the bottom, which is inclined to allow water to be drained to a low-lying area of ​​the bottom wall when there is water in the drainage chamber 8.1. When condensation occurs in the drainage pipe, the condensate is directed to the low-lying area to better reduce its impact on steam flow.

[0079] Furthermore, in order to drain the condensate in the drain pipe 8 after steam cleaning, a drain outlet can be provided in the low-lying area of ​​the bottom wall to drain the water in the drain chamber 8.1 to the outside of the drain pipe 8. At the same time, the drain outlet is provided with a switch to control the opening / closing of the drain outlet, such as a shut-off valve installed in the drain outlet and controlled by opening / closing the drain outlet, or a cap detachably connected to the drain pipe 8 and used to seal the drain outlet. The opening / closing of the drain outlet can be controlled by installing / removing the cap on the drain pipe 8.

[0080] During steam cleaning, the switch is used to seal the drain outlet (by closing the shut-off valve or installing a cover to seal the drain outlet) to prevent steam leakage. After steam cleaning is completed, the switch is operated (by opening the shut-off valve or removing the cover to seal the drain outlet) to ensure the drain outlet is unobstructed, thereby draining the condensate in the drainage chamber 8.1 and preventing excessive accumulation of condensate.

[0081] While the above solution can introduce steam into the cleaning tank 1.11 for cleaning while minimizing interference with the cleaning space of the cleaning tank 1.11, it cannot effectively clean the areas where oil stains accumulate in the cleaning tank 1.11, i.e., the inner wall of the cleaning tank 1.11.

[0082] Therefore, as a further improvement, in this embodiment, as shown in the appendix Figure 3 and 4 As shown, the steam inlet 1.12 is positioned close to the opening of the cleaning tank 1.11, and a connecting wall 1.11a is formed protruding from the inner wall of the cleaning tank 1.11, located above the steam inlet 1.12. Simultaneously, the end of the connecting wall 1.11a away from the inner wall of the cleaning tank 1.11 has a downwardly extending guide wall 1.11b, which is configured to guide the steam entering the cleaning tank 1.11 from the steam inlet 1.12 to the inner wall of the cleaning tank 1.11 located below the steam inlet 1.12. At this time, when steam cleaning is performed as described above, the steam... Figure 4As shown by the middle arrow, after flowing from the outlet 8.3 to the steam inlet 1.12, the steam will flow out from the steam inlet 1.12 and collide with the connecting wall 1.11a and the guide wall 1.11b. The guide wall 1.11b guides the steam downwards to the inner wall of the cleaning tank 1.11, so as to better clean the oil stains that accumulate in the cleaning tank 1.11, i.e., the inner wall of the cleaning tank 1.11, and improve the overall cleaning effect. At the same time, by setting the connecting wall 1.11a and the guide wall 1.11b, water can also be prevented from splashing into the drainage cavity 8.1 from the steam inlet 1.12 when using the cleaning tank 1.11 to clean items, so as to better reduce the possibility of scale accumulation and blockage in the drainage cavity 8.1.

[0083] Furthermore, in order to better reduce the generation of condensate in the drainage cavity 8.1, in this embodiment, as shown in the attached... Figure 3 and 4 As shown, a first heating element 9 for heating can also be attached to the outer periphery of the drainage tube 8 (the first heating element 9 can be an electric heating device, that is, a device that has an electric heating structure such as an electric heating wire inside, which can heat when the power is on and does not heat when the power is off).

[0084] When steam cleaning is performed as described above, the first heating element 9 is energized to heat the drainage pipe 8. This can, on the one hand, slow down the condensation of steam in the drainage chamber 8.1, reduce the possibility of scale buildup and blockage in the drainage chamber 8.1, and allow more steam to be output to the cleaning tank 1.11 for steam cleaning, thereby improving the cleaning effect. On the other hand, it can reduce the heat transfer between the steam and the external space, allowing the steam to maintain a higher temperature for better cleaning of oil stains, thus improving the cleaning effect.

[0085] After the first heating element 9 is set as described above, if only one side of the first heating element 9 is attached to the drain pipe 8, most of the heat generated by the first heating element 9 will be transferred to the air from the other sides, resulting in excessive energy waste.

[0086] In this embodiment, as shown in the appendix Figure 3 and 4As shown, the first heating element 9 is preferably clamped between the drain pipe 8 and the tank 1.1, so that: the two sides of the first heating element 9 are respectively in contact with the drain pipe 8 and the tank 1.1. That is, one side of the first heating element 9 is in contact with the drain pipe 8, and the other side is in contact with the tank 1.1. In this way, when the first heating element 9 is heating, it can not only transfer some heat to the drain pipe 8 as described above to improve the cleaning effect, but also transfer some heat to the tank 1.1, directly heating the tank 1.1. By heating the tank 1.1, the side wall of the cleaning tank 1.11 heats up, and the oil stains can be more easily removed from the heated cleaning tank 1.11. This effectively improves energy utilization and further optimizes the steam cleaning effect. Moreover, by heating the tank 1.1, after steam cleaning, the moisture inside the cleaning tank 1.11 can be better driven to evaporate, improving the dryness of the tank 1 after steam cleaning, thus achieving a more satisfactory cleaning effect.

[0087] In the above scheme, the first heating element 9 can be independently switched on and off. Alternatively, the first heating element 9 can be electrically connected to the water purification control module, which supplies power to the first heating element 9 and controls its switching on and off. As described above, through the switching structure, when the water purification control module controls steam cleaning, it simultaneously controls the first heating element 9 to turn on; and through the switching structure, when the steam cleaning ends, it simultaneously controls the first heating element 9 to turn off.

[0088] Furthermore, as shown in the appendix Figure 2 As shown, in this embodiment, the first control valve 2.12 is preferably located in the portion of the first water outlet pipe 2.3 between the filter assembly 2.1 and the steam generator 3. This ensures that when cleaning is not performed, the water pressure in the first water outlet pipe 2.3 will act on the first control valve 2.12 rather than the steam generator 3, thus providing better protection for the steam generator 3.

[0089] Example 2:

[0090] Based on the solution in Embodiment 1, considering that steam cleaning may only be used once every few days or even weeks, using only the water purification unit to supply water to the steam generator 3 results in a low overall cost-effectiveness of the product and fails to fully utilize the performance of the water purification unit.

[0091] Based on this, as attached Figure 5 As shown, the first water outlet pipe 2.3 has a portion located between the first control valve 2.12 and the filter assembly 2.1, which is connected to the second water outlet pipe 2.4; the end of the second water outlet pipe 2.4 away from the first water outlet pipe 2.3 is connected to the first water faucet 2.5.

[0092] At this time, when the second control valve 2.6, booster pump 2.1f and reverse osmosis filter 2.1c are not in use, the first water outlet 2.5 is turned on, and the first water outlet 2.5 can output filtered water that has passed through the first water purification filter 2.1b and the second water purification filter 2.1g, which can be used for cleaning or cooking.

[0093] When the second control valve 2.6 is present, opening the first water outlet 2.5 and the second control valve 2.6 will allow the first water outlet 2.5 to output filtered water for washing or cooking.

[0094] At this point, in order to more conveniently produce water through the first water tap 2.5, as shown in the attached... Figure 5 As shown, a first high-pressure switch 2.7 is installed in the second water outlet pipe 2.4, which is configured to detect the water pressure between it and the first water outlet tap 2.5.

[0095] The second control valve 2.6 and the first high-pressure switch 2.7 are both electrically connected to the water purification control module, and the water purification control module is configured to receive the water pressure value detected by the first high-pressure switch 2.7 and control whether the first water outlet faucet 2.5 dispenses water based on the water pressure value.

[0096] When the first water tap 2.5 is opened, the water path between the first high-pressure switch 2.7 and the first water tap 2.5 is connected to the outside air, thereby reducing the water pressure in that part of the water path. The water purification control module is set with a predetermined water pressure value. When the water pressure value detected by the first high-pressure switch 2.7 and transmitted to the water purification control module is lower than the predetermined water pressure value, the water purification control module controls the second control valve 2.6 to open, and the first water tap 2.5 outputs filtered water.

[0097] When the first water tap 2.5 is closed, water accumulates in the water path between the first high-pressure switch 2.7 and the first water tap 2.5, causing the water pressure to increase. The first high-pressure switch 2.7 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 second control valve 2.6 to close, and the first water tap 2.5 stops outputting filtered water.

[0098] When the booster pump 2.1f and reverse osmosis filter cartridge 2.1c are also installed, and the first water outlet faucet 2.5 is opened, the water purification control module synchronously controls the booster pump 2.1f and wastewater control valve 2.1e to open, so that the water purification unit can produce filtered water and output it from the first water outlet faucet 2.5. When the first water outlet faucet 2.5 is closed, the water purification control module synchronously controls the booster pump 2.1f and wastewater control valve 2.1e to close.

[0099] Example 3:

[0100] Based on Embodiment 1 or Embodiment 2, in order to make the sink equipment more adaptable to the needs of kitchen use.

[0101] As attached Figure 5 As shown, the first water outlet pipe 2.3 has a portion located between the first control valve 2.12 and the filter group 2.1, and this portion is also connected to the third water outlet pipe 2.8; the end of the third water outlet pipe 2.8 away from the first water outlet pipe 2.3 is connected to the second water outlet faucet 2.9; and the third water outlet pipe 2.8 is provided with a second heating element 2.10 for heating the water flowing in the third water outlet pipe 2.8 (the second heating element 2.10 can be an electric heating device, that is, a device with an electric heating structure such as an electric heating wire inside, which can heat when energized and does not heat when de-energized).

[0102] At this time, when the second control valve 2.6, booster pump 2.1f and reverse osmosis filter 2.1c are not in use, the second water outlet 2.9 and the second heating element 2.10 are turned on. The second water outlet 2.9 can output hot filtered water that has been filtered by the first water purification filter 2.1b and the second water purification filter 2.1g, which can be used for cleaning or cooking.

[0103] When the second control valve 2.6 is present, opening the second water faucet 2.9, the second heating element 2.10, and the second control valve 2.6 will allow the second water faucet 2.9 to output filtered, hot water for washing or cooking.

[0104] At this point, in order to more conveniently produce water through the second water tap 2.9, as shown in the attached... Figure 5 As shown, the third water outlet pipe 2.8 has a portion located between the second heating element 2.10 and the second water outlet faucet 2.9. This portion is equipped with a second high-pressure switch 2.11, which is configured to detect the water pressure between it and the second water outlet faucet 2.9.

[0105] The second heating element 2.10 is electrically connected to the water purification control module. The water purification control module supplies power to the second heating element 2.10 and controls the second heating element 2.10 to open / close. At the same time, the second control valve 2.6 and the second high-pressure switch 2.11 are both electrically connected to the water purification control module. The water purification control module is configured to receive the water pressure value detected by the second high-pressure switch 2.11 and control whether the second water faucet 2.9 dispenses water based on the water pressure value.

[0106] When the second water tap 2.9 is opened, the water path between the second high-pressure switch 2.11 and the second water tap 2.9 is connected to the outside air, thereby reducing the water pressure in that part of the water path. The water purification control module is set with a predetermined water pressure value. When the water pressure value detected by the second high-pressure switch 2.11 is lower than the predetermined water pressure value, the water purification control module controls the second control valve 2.6 to open, the second heating element 2.10 to turn on, and the second water tap 2.9 to output hot filtered water.

[0107] When the second water tap 2.9 is closed, water accumulates in the water path between the second high-pressure switch 2.11 and the second water tap 2.9, causing the water pressure to increase. The second high-pressure switch 2.11 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 second control valve 2.6 and the second heating element 2.10 to close, and the second water tap 2.9 stops outputting filtered water.

[0108] When the booster pump 2.1f and reverse osmosis filter cartridge 2.1c are also installed, and the second water outlet faucet 2.9 is opened, the water purification control module synchronously controls the booster pump 2.1f and wastewater control valve 2.1e to open, so that the water purification unit can produce filtered water and output it from the second water outlet faucet 2.9. When the second water outlet faucet 2.9 is closed, the water purification control module synchronously controls the booster pump 2.1f and wastewater control valve 2.1e to close.

[0109] Furthermore, considering the arrangement of the second heating element 2.10 and the steam generator 3, water in the first outlet pipe 2.3 is difficult to flow into the second heating element 2.10 and the steam generator 3. Therefore, in order to improve the heating effect or steam conversion efficiency, as shown in the attached... Figure 5 As shown, in this embodiment, the first water outlet pipe 2.3 has: a first part connected to the second water outlet pipe 2.4, a second part connected to the third water outlet pipe 2.8, and a third part located between the first part and the second part; the third part of the first water outlet pipe 2.3 is provided with a water pump 6, which is configured to: draw water from the filter group 2.1 and deliver it to the second part of the first water outlet pipe 2.3.

[0110] When a water purification control module is installed, the water pump 6 is electrically connected to the water purification control module, which supplies power to the water pump 6 and controls its on / off operation. During steam cleaning and hot filtered water production as described above, the water purification control module synchronously controls the water pump 6 to turn on; when steam cleaning and hot filtered water production are not performed, the water purification control module synchronously controls the water pump 6 to turn off.

[0111] It should be further noted that the steam generator 3, first control valve 2.12, second control valve 2.6, third control valve 7.2, first water purification filter element 2.1b, second water purification filter element 2.1g, reverse osmosis filter element 2.1c, wastewater control valve 2.1e, booster pump 2.1f, check valve 4, first high-pressure switch 2.7, second high-pressure switch 2.11, first heating element 9, second heating element 2.10, and water pump 6 described in any of the above embodiments are all commonly used devices in kitchen equipment.
