TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen cleaning equipment, and more particularly to a sink assembly. BACKGROUND

[0002] With the improvement of living quality and the enhancement of health awareness, consumers have higher requirements for the cleanliness of domestic water, and the application demand of integrated water treatment devices is increasing.

[0024] One end of the connecting wall away from the inner wall of the cleaning tank has a guide wall extending downward, which is configured to guide the steam entering the cleaning tank from the steam inlet to the inner wall of the cleaning tank below the steam inlet.

[0025] As a further preferred solution, the outer periphery of the drainage tube is adhered with: a first heating element for heating.

[0026] As a further preferred solution, the first heating element is clamped between the drainage tube and the trough body, so that: the two side surfaces of the first heating element are respectively in contact with the drainage tube and the trough body.

[0027] As a further preferred embodiment, the water purification unit includes: a filter group for filtering the inflowing water and delivering the filtered water to the first water outlet pipeline;

[0050] The present invention is specifically described below with reference to the embodiments:

[0051] Example 1:

[0052] The water tank assembly 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 1 As shown, the tank body 1.1 comprises an upwardly opening cleaning tank 1.11, and also includes a drain pipe 1.2 connected to the tank body 1.1 and for draining the liquid within the cleaning tank 1.11. Specifically, the bottom wall of the cleaning tank 1.11 is provided with an outlet for draining the liquid within 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 house's sewage pipe, so that the liquid within the cleaning tank 1.11 can be discharged outward through the drain pipe 1.2 and discharged into the house's sewage pipe.

[0053] The tank body 1.1 is generally also provided with a tap 1.3 for conveying tap water to the cleaning tank 1.11.

[0054] After the sink 1 is used (for example, to wash items in the washing tank 1.11), tap water is supplied to the washing tank 1.11 through 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 for a long time in the kitchen, it is found that in a working environment with heavy oil smoke, the sink 1 often accumulates a lot of oil stains due to the direct adhesion of oil smoke or the cleaning of oily items. Simply using tap water is often not enough to effectively clean the oily sink 1. As a result, after long-term use, the sink 1, especially the washing tank 1.11 as the washing space, is prone to the problem of oil stains accumulating, which seriously affects the user experience.

[0055] Based on this, in order to better clean the oil stains, the steam generator 3 is preferably used in this embodiment to solve the above problem by converting tap water into steam and transporting it to the cleaning tank 1.11 to better clean the oil stains.

[0056] However, in actual use, it is found that there are often many impurities in tap water. If the tap water is directly transported to the steam generator 3 to be converted into steam, the impurities in the tap water will easily have a negative impact on the steam generator 3, which will not only affect the effect of forming steam, but also easily cause damage to the steam generator 3, thereby reducing the service life of the steam generator 3.

[0057] Based on this, a water purification unit is provided in this embodiment for supplying water and filtering 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.

[0058] Specific: as attached Figure 2 As shown, in this embodiment, a water purification unit is provided for supplying water inflow and filtering the inflowing water, which includes: a filter group 2.1 for filtering the inflowing water and conveying the filtered water to a first water outlet pipe 2.3, and a water inlet pipe 2.2 for supplying water inflow and conveying the inflowing water into the filter group 2.1.

[0059] To be precise, as Figure 2As shown, the filter assembly 2.1 in this embodiment includes a water supply pipeline 2.1a through which water circulates. One end of the pipeline has a filtered water inlet for water to flow into the pipeline 2.1a, and the other end has a filtered water outlet for water to flow out of the pipeline 2.1a. Furthermore, the pipeline 2.1a is provided with at least a first water purification filter element 2.1b for filtering the water flowing into the pipeline 2.1a. The first water purification filter element 2.1b primarily comprises a water purification channel connected to the pipeline 2.1a for water to flow through, and a filter membrane disposed within the water purification channel for filtering the water flowing therethrough.

[0060] One end of the water inlet pipe 2.2 is connected to the tap water line, and the other end is connected to the filter inlet of the water supply pipe 2.1a. This allows tap water to enter the filter group 2.1 through the water inlet pipe 2.2 for filtration. Simultaneously, the water purification unit is connected to a first water outlet pipe 2.3, through which the filtered water flows out. In other words, the filter outlet of the water supply pipe 2.1a is connected to the first water outlet pipe 2.3, allowing the filtered water from the filter group 2.1 to be discharged outward through the first water outlet pipe 2.3.

[0061] In order to improve the filtering effect, Figure 2 As shown, other filter element structures can also be provided in the water supply pipeline 2.1a, such as a second water purification filter element 2.1g (the second water purification filter element 2.1g mainly includes: a clean water flow channel connected to the water supply pipeline 2.1a for water to flow through, and a filter membrane arranged in the clean water flow channel to filter the water flowing through, and the filter membrane of the second water purification filter element 2.1g and the filter membrane of the first water purification filter element 2.1b can be set differently according to needs).

[0062] 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. The first water outlet pipe 2.3 is provided with: a steam generator 3 for converting water into steam and transmitting the steam to the cleaning tank 1.11; and a first control valve 2.12 for controlling the opening / closing of the first water outlet pipe 2.3 (the opening / closing of the first water outlet pipe 2.3 is controlled by controlling the opening / closing of the first control valve 2.12).

[0063] When the water tank assembly is actually installed and used, the end of the water inlet pipe 2.2 away from the filter group 2.1 is connected to the tap water pipe. When it is necessary to steam clean the cleaning tank 1.11:

[0064] By opening first control valve 2.12 to unblock first water outlet pipe 2.3, connecting steam generator 3 to a power source and turning on steam generator 3, tap water enters filter group 2.1 through water inlet pipe 2.2 for filtration, producing filtered water. This filtered water then flows through a portion of first water outlet pipe 2.3 into steam generator 3, where it is converted into steam. The steam then flows through the remaining portion of first water outlet pipe 2.3 into cleaning tank 1.11, steam-cleaning the interior walls of cleaning tank 1.11.

[0065] The steam cleaning can be stopped by closing the first control valve 2.12 to close the first water outlet pipe 2.3 and turning off the steam generator 3.

[0066] The above-mentioned water tank assembly capable of using steam to clean the cleaning tank 1.11 can not only discharge high-temperature steam into the cleaning tank 1.11 in a direction, so as to better clean the oil stains in the cleaning tank 1.11, but also improve the cleanliness of the water tank 1 and provide a better user experience.

[0067] Moreover, the above solution uses filtered water as the water source for the steam generator 3 , which can better prevent impurities in tap water from causing adverse effects on the steam generator 3 and improve the long-term service life of the steam generator 3 .

[0068] In the above solution, the first control valve 2.12 and the steam generator 3 can be directly controlled manually to achieve the above steam cleaning step, but the operation is relatively complicated.

[0069] For ease of operation, in this embodiment, the water purification unit is preferably provided with a water purification control module electrically connected to a power source. The steam generator 3 is electrically connected to the water purification control module, which supplies power to the steam generator 3 and controls its on / off operation. A first control valve 2.12 is a solenoid valve that controls the opening / closing of the first water outlet pipeline 2.3. The first control valve 2.12 is electrically connected to the water purification control module, which controls the opening / closing of the first water outlet pipeline 2.3 by opening / closing the first control valve 2.12.

[0070] At the same time, a switch structure electrically connected to the water purification control module is also provided. The switch structure is configured to: control the steam generator 3 and the first control valve 2.12 to open synchronously 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.

[0071] In one embodiment, the switch structure may include a wash on button and a wash off button provided on the water tank 1 or the water purification unit. The wash on button is configured to be electrically connected to the water purification control module and can control the steam generator 3 and the first control valve 2.12 to be opened synchronously; the wash off button is configured to be electrically connected to the water purification control module and can control the steam generator 3 and the first control valve 2.12 to be closed synchronously.

[0072] Based on the above solution, the water supply pipeline 2.1a may also be equipped with a booster pump 2.1f that pressurizes the water in the pipeline and delivers the pressurized water to the first water outlet pipeline 2.3; 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 water outlet pipeline 2.3. The reverse osmosis filter element 2.1c has a wastewater pipe 2.1d for discharging wastewater from the filtration process. The wastewater pipe is equipped with a wastewater control valve 2.1e for controlling its opening / closing (the opening / closing of the wastewater control valve 2.1e controls the opening / closing of the wastewater pipe 2.1d). 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.

[0073] When the water purification unit is provided with a water purification control module, the booster pump 2.1f is electrically connected to the water purification control module, and the water purification control module supplies power to the booster pump 2.1f and controls the booster pump 2.1f to switch on and off; the wastewater control valve 2.1e is an electromagnetic valve that controls the opening / closing of the wastewater pipe 2.1d, which is electrically connected to the water purification control module. The water purification control module controls the wastewater control valve 2.1e to open / close and control the opening / closing of the wastewater pipe 2.1d.

[0074] At this time, the switch structure is configured to: control the steam generator 3, first control valve 2.12, booster pump 2.1f, and wastewater control valve 2.1e to be opened synchronously, thereby generating steam to clean the cleaning tank 1.11 as described above; and also control the steam generator 3, first control valve 2.12, third control valve 7.2, booster pump 2.1f, and wastewater control valve 2.1e to be closed synchronously. For example, the cleaning on button is configured to be electrically connected to the water purification control module and to control the steam generator 3, first control valve 2.12, booster pump 2.1f, and wastewater control valve 2.1e to be opened synchronously; and the cleaning off button is configured to be electrically connected to the water purification control module and to control the steam generator 3, first control valve 2.12, booster pump 2.1f, and wastewater control valve 2.1e to be closed synchronously.

[0075] In some embodiments, the water inlet pipe 2.2 may further be provided with a second control valve 2.6 for controlling the opening / closing of the water inlet pipe 2.2 (the opening / closing of the water inlet pipe 2.2 is controlled by controlling the second control valve 2.6 ) to control whether water enters the water purification unit.

[0076] When the water purification unit is equipped with a water purification control module, second control valve 2.6 is a solenoid valve that controls the opening / closing of water inlet pipe 2.2. It is electrically connected to the water purification control module, which in turn controls the opening / closing of wastewater control valve 2.1e, thereby controlling the opening / closing of water inlet pipe 2.2. The switch mechanism is configured to synchronously open second control valve 2.6, steam generator 3, first control valve 2.12, booster pump 2.1f, and wastewater control valve 2.1e to generate steam for cleaning tank 1.11 as described above; and to synchronously close 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. For example, the cleaning on button is configured as follows: electrically connected to the water purification control module, and can control the second control valve 2.6, steam generator 3, first control valve 2.12, boost pump 2.1f and wastewater control valve 2.1e to open synchronously; the cleaning off button is configured as follows: electrically connected to the water purification control module, and can control the second control valve 2.6, steam generator 3, first control valve 2.12, boost pump 2.1f and wastewater control valve 2.1e to close synchronously.

[0077] Furthermore, the outlet end of the first water outlet pipe 2.3 can be directly inserted into the cleaning tank 1.11 through the notch of the cleaning tank 1.11 to deliver steam to the cleaning tank 1.11 during steam cleaning. However, this is likely to interfere with the cleaning space of the cleaning tank 1.11 and affect the normal cleaning operation.

[0078] Based on this, in this embodiment, as shown in the attached Figure 3 To the attached Figure 4 As shown in the figure, the tank body 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 the fluid outside the cleaning tank 1.11 can flow into the cleaning tank 1.11 from the steam inlet 1.12.

[0079] At the same time, the outer periphery of the tank body 1.1 is also provided with a drainage tube 8 located outside the cleaning tank 1.11. The drainage tube 8 has a hollow interior formed with a drainage cavity 8.1. The tube wall is provided with an inlet 8.2, which connects the drainage cavity 8.1 with the space outside the drainage tube 8, and an outlet 8.3, which connects the drainage cavity 8.1 with the space outside the drainage tube 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. After steam is generated as described above, the steam in the first water outlet pipe 2.3 can enter the drainage cavity 8.1 of the drainage tube 8 through the inlet 8.2, flow through the drainage cavity 8.1, and then flow from the outlet 8.3 to the steam inlet 1.12. Finally, it flows from the steam inlet 1.12 into the cleaning tank 1.11, thereby steam cleaning the cleaning tank 1.11.

[0080] Although the above solution can introduce steam into the cleaning tank 1.11 for cleaning while avoiding interference with the cleaning space of the cleaning tank 1.11 as much as possible, it cannot better clean the oil accumulation area of ​​the cleaning tank 1.11, that is, the inner wall of the cleaning tank 1.11.

[0081] Therefore, as a further improvement, in this embodiment, as shown in the attached Figure 3 and 4 As shown, the steam inlet 1.12 is located near the notch of the cleaning tank 1.11, and the inner wall of the cleaning tank 1.11 is formed with a protruding connecting wall 1.11a located above the steam inlet 1.12. At the same time, 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 below the steam inlet 1.12. At this time, when steam cleaning is performed as described above, the steam is attached to the cleaning tank 1.11. Figure 4 As shown by the middle arrow, after flowing from outlet 8.3 to steam inlet 1.12, the steam will flow out of steam inlet 1.12 and collide with connecting wall 1.11a and guide wall 1.11b. Guide wall 1.11b then directs the steam downward to the inner wall of cleaning tank 1.11, thereby better cleaning the oil-collected areas of cleaning tank 1.11, i.e., the inner wall of cleaning tank 1.11, and improving the overall cleaning effect. Furthermore, the provision of connecting wall 1.11a and guide wall 1.11b also prevents water from splashing from steam inlet 1.12 into drainage chamber 8.1 when cleaning items in cleaning tank 1.11, thereby further reducing the possibility of scale accumulation in drainage chamber 8.1 and causing blockage.

[0082] In the above solution, the extension path and length of drainage tube 8 are determined based on the placement of steam inlet 1.12, which is determined based on cleaning requirements. To clean a wider area, drainage tube 8 often needs to be longer. This can lead to condensation when steam enters drainage chamber 8.1, resulting in a large amount of condensed water in drainage chamber 8.1. This, in turn, can lead to the accumulation of scale in drainage chamber 8.1, hindering the smooth flow of steam and reducing cleaning efficiency.

[0083] Based on this, 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 with an electric heating structure such as a heating wire inside, which can heat by turning on the power and not heat by turning off the power).

[0084] When steam cleaning is performed as described above, by energizing the first heating element 9, the first heating element 9 heats the drainage tube 8. On the one hand, it can slow down the condensation of steam in the drainage chamber 8.1, reduce the possibility of scale accumulation and blockage in the drainage chamber 8.1, and enable 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 weaken the heat transfer effect between the steam and the external space, so that the steam can better maintain a higher temperature to better clean the oil stains, thereby 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 drainage tube 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 attached Figure 3 and 4As shown, the first heating element 9 is preferably sandwiched between the drainage tube 8 and the tank body 1.1, so that the two side surfaces of the first heating element 9 respectively contact the drainage tube 8 and the tank body 1.1. That is, one side of the first heating element 9 contacts the drainage tube 8, and the other side contacts the tank body 1.1. In this way, when the first heating element 9 is heating, it not only transfers some heat to the drainage tube 8 as described above to improve the cleaning effect, but also transfers some heat to the tank body 1.1, directly heating the tank body 1.1. By heating the tank body 1.1, the side walls of the cleaning tank 1.11 are heated, and oil stains can be more easily removed from the heated cleaning tank 1.11, effectively improving energy utilization and further optimizing the steam cleaning effect. Moreover, by heating the tank body 1.1, after steam cleaning is completed, the water inside the cleaning tank 1.11 can be better driven to evaporate, thereby improving the dryness of the water tank 1 after steam cleaning, thereby achieving a more satisfactory cleaning effect.

[0087] In the above solution, 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 on and off. As described above, the switch structure allows the water purification control module to simultaneously turn on the first heating element 9 when steam cleaning is in progress; and to simultaneously turn off the first heating element 9 when steam cleaning is complete.

[0088] Furthermore, as attached Figure 2 As shown, in this embodiment, the first control valve 2.12 is preferably disposed in the portion of the first water outlet pipe 2.3 between the filter group 2.1 and the steam generator 3. This ensures that when not being cleaned, the water pressure in the first water outlet pipe 2.3 permanently acts on the first control valve 2.12 rather than the steam generator 3, thereby better protecting the steam generator 3.

[0089] Example 2:

[0090] Based on the solution of the first embodiment, it is further considered that when the steam is generated in real time by the steam generator 3 and delivered to the cleaning tank 1.11 in real time, the cleaning effect may sometimes not reach a satisfactory level.

[0091] Based on this, as attached Figure 5As shown, in the direction from the water purification unit to the cleaning tank 1.11, specifically from the filter group 2.1 to the cleaning tank 1.11, the first water outlet pipe 2.3 is sequentially provided with: a first control valve 2.12, a steam generator 3, and a pressure-limiting structure 7 that receives steam output from the steam generator 3 and releases the steam into the cleaning tank 1.11 when the received steam reaches a predetermined pressure. This ensures that the steam delivered to the cleaning tank 1.11 has a certain pressure before reaching the predetermined pressure. This ensures that the steam delivered to the cleaning tank 1.11 has a certain pressure, which can better impact and clean oil stains, improving the cleaning effect of a single area. Furthermore, this allows the steam delivered to the cleaning tank 1.11, under a certain degree of high pressure, to be transported further within the cleaning tank 1.11, allowing more areas within the cleaning tank 1.11 to be cleaned by the steam, thereby improving the cleaning effect of the entire area.

[0092] Specifically, as attached Figure 5 As shown, the pressure limiting structure 7 in this embodiment includes: a pressure chamber 7.1, a pressure sensor 7.3 and a third control valve 7.2.

[0093] Specifically, the pressure chamber 7.1 is located in the portion of the first water outlet pipeline 2.3 between the steam generator 3 and the cleaning tank 1.11. It contains a steam storage chamber 7.11. One end of this steam storage chamber 7.11 is connected to the steam outlet of the steam generator 3 via a portion of the first water outlet pipeline 2.3 (the portion of the first water outlet pipeline 2.3 located between the pressure chamber 7.1 and the steam generator 3). The other end of this steam storage chamber 7.11 is connected to the cleaning tank 1.11 via another portion of the first water outlet pipeline 2.3 (the portion of the first water outlet pipeline 2.3 located between the pressure chamber 7.1 and the cleaning tank 1.11). This allows steam output from the steam generator 3 to be input into the steam storage chamber 7.11 and then enter the cleaning tank 1.11 through the steam storage chamber 7.11. A pressure sensor 7.3 is adapted to fit within the steam storage chamber 7.11 and monitors the air pressure within the steam storage chamber 7.11. The third control valve 7.2 is provided in the portion of the first water outlet pipe 2.3 between the pressure chamber 7.1 and the cleaning tank 1.11 and is a solenoid valve for controlling the opening / closing of the first water outlet pipe 2.3 (the opening / closing of the first water outlet pipe 2.3 is controlled by controlling the opening / closing of the third control valve 7.2).

[0094] The pressure-limiting structure 7 also includes a pressure-limiting control module electrically connected to a power source. Both the pressure sensor 7.3 and the third control valve 7.2 are electrically connected to the pressure-limiting control module. The pressure-limiting control module is configured to control the third control valve 7.2 to open when the pressure sensor 7.3 detects that the pressure within the steam storage chamber 7.11 exceeds a specified pressure value. Specifically, when the water tank assembly is installed and in use, the pressure-limiting control module is electrically connected to the power source and supplies power to the third control valve 7.2 and the pressure sensor 7.3. During this time, when steam is generated as described above, it is continuously fed into the steam storage chamber 7.11, continuously increasing the pressure within the chamber. Simultaneously, the pressure sensor 7.3 monitors the pressure within the chamber 7.11 and transmits the pressure to the pressure-limiting control module. The pressure-limiting control module is set with a specified pressure value, which is determined based on actual needs.

[0095] When pressure sensor 7.3 detects that the pressure in steam storage chamber 7.11 exceeds a predetermined pressure, the pressure limiting control module controls third control valve 7.2 to open, allowing the accumulated steam to be transported to cleaning tank 1.11 to clean the oil. When cleaning is complete, third control valve 7.2 is closed.

[0096] At the same time, the third control valve 7.2 can also be electrically connected to the above-mentioned water purification control module. When the switch structure controls the steam generator 3 and the first control valve 2.12 to be closed, the third control valve 7.2 is synchronously controlled to be closed.

[0097] Example 3:

[0098] Based on the solution in Example 1 or Example 2, considering that steam cleaning is often used once every few days or even weeks, the water purification unit is only used to supply water to the steam generator 3. The overall product has a low cost-effectiveness and cannot bring into play the performance of the water purification unit.

[0099] Based on this, as attached Figure 6 As shown in FIG7 , the first water outlet pipe 2.3 has a portion disposed between the first control valve 2.12 and the filter group 2.1, which portion 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 outlet tap 2.5.

[0100] At this time, when there is no second control valve 2.6, booster pump 2.1f and reverse osmosis filter element 2.1c, open the first water outlet faucet 2.5, and the first water outlet faucet 2.5 can output filtered water filtered by the first water purification filter element 2.1b and the second water purification filter element 2.1g for washing or cooking.

[0101] When the second control valve 2.6 is opened, the first water outlet 2.5 outputs filtered water, which is used for cleaning or cooking.

[0102] At this time, in order to make the water making more convenient through the first water outlet 2.5, as shown in FIG. 7, a first high-pressure switch 2.7 is arranged in the second water outlet pipeline 2.4, which is configured to detect the water pressure between the first high-pressure switch 2.7 and the first water outlet 2.5. Figure 6

[0103] 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 to control whether the first water outlet 2.5 outputs water according to the water pressure value.

[0104] That is, when the first water outlet 2.5 is opened, the water path between the first high-pressure switch 2.7 and the first water outlet 2.5 is connected to the external air, thereby reducing the water pressure of the part of the water path. The water purification control module is provided with a predetermined water pressure value, and 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 outlet 2.5 outputs filtered water.

[0105] When the first water outlet 2.5 is closed, the water pressure in the water path between the first high-pressure switch 2.7 and the first water outlet 2.5 increases due to the accumulation of water. When the water pressure value detected by the first high-pressure switch 2.7 and transmitted to the water purification control module is higher than the predetermined water pressure value, the water purification control module controls the second control valve 2.6 to close, and the first water outlet 2.5 does not output filtered water.

[0106] When the booster pump 2.1f and the reverse osmosis filter element 2.1c are also arranged, when the first water outlet 2.5 is opened, the water purification control module synchronously controls the booster pump 2.1f and the waste water control valve 2.1e to open, so that the water purification unit can make filtered water and output from the first water outlet 2.5. When the first water outlet 2.5 is closed, the water purification control module synchronously controls the booster pump 2.1f and the waste water control valve 2.1e to close.

[0107] Embodiment Four:

[0108] Based on the first embodiment or the second embodiment or the third embodiment, in order to make the sink assembly more suitable for the use requirements of the kitchen.

[0109] As shown in FIG. 8, the first water outlet 2.5 is arranged on the side wall of the sink assembly, and the second water outlet 2.4 is arranged on the top wall of the sink assembly. Figure 6 ​As shown in FIG. 7 , the first water outlet pipe 2.3 includes a portion disposed between the first control valve 2.12 and the filter assembly 2.1. This portion is further connected to a third water outlet pipe 2.8. An end of the third water outlet pipe 2.8 remote from the first water outlet pipe 2.3 is connected to a second water outlet faucet 2.9. Furthermore, the third water outlet pipe 2.8 is provided with a second heating element 2.10 for heating water flowing through the third water outlet pipe 2.8. (The second heating element 2.10 may be an electric heating device, i.e., a device having an internal heating structure such as a heating wire, which heats when powered on and stops when powered off.)

[0110] At this time, when the second control valve 2.6, the booster pump 2.1f and the reverse osmosis filter element 2.1c are not in use, the second water outlet faucet 2.9 and the second heating element 2.10 are opened, and the second water outlet faucet 2.9 can output hot filtered water filtered by the first water purification filter element 2.1b and the second water purification filter element 2.1g for washing or cooking.

[0111] When the second control valve 2.6 is provided, the second water outlet faucet 2.9, the second heating element 2.10 and the second control valve 2.6 are opened, and the second water outlet faucet 2.9 can output filtered, hot filtered water for washing or cooking.

[0112] At this time, in order to make water more conveniently 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 disposed between the second heating element 2.10 and the second water outlet tap 2.9, and the portion is provided with a second high-pressure switch 2.11, which is configured to detect the water pressure between the second water outlet tap 2.9 and the second high-pressure switch 2.11.

[0113] The second heating element 2.10 is electrically connected to the water purification control module, which supplies power to the second heating element 2.10 and controls its on / off state. Furthermore, 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 detected by the second high-pressure switch 2.11 and control whether the second water outlet faucet 2.9 dispenses water based on the water pressure.

[0114] That is, when the second water outlet faucet 2.9 is opened, the water path between the second high-pressure switch 2.11 and the second water outlet faucet 2.9 is connected to the outside air, thereby reducing the water pressure in this part of the water path. The water purification control module is set to a predetermined water pressure value. If the water pressure value detected by the second high-pressure switch 2.11 and transmitted to the water purification control module falls below 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 outlet faucet 2.9 to output hot filtered water.

[0115] When the second water outlet faucet 2.9 is closed, water accumulates in the waterway between the second high-pressure switch 2.11 and the second water outlet faucet 2.9, causing the water pressure to increase. The water pressure value detected by the second high-pressure switch 2.11 and transmitted to the water purification control module exceeds 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 outlet faucet 2.9 stops discharging filtered water.

[0116] When a booster pump 2.1f and a reverse osmosis filter element 2.1c are also provided and the second water outlet tap 2.9 is opened, the water purification control module simultaneously controls the booster pump 2.1f and the wastewater control valve 2.1e to open, allowing the water purification unit to produce filtered water and output it from the second water outlet tap 2.9. When the second water outlet tap 2.9 is closed, the water purification control module simultaneously controls the booster pump 2.1f and the wastewater control valve 2.1e to close.

[0117] Furthermore, in this embodiment, when the aforementioned pressure-limiting structure 7 is also provided, a second heating element 2.10 can also be placed within the pressure chamber 7.1, separated from the steam storage chamber 7.11 by a partition 7.12. Thus, when steam is generated for steam cleaning as described above, the water purification control module can simultaneously control the activation of the second heating element 2.10, allowing it to heat and insulate the steam in the steam storage chamber 7.11, thereby reducing condensation within the steam storage chamber 7.11. When steam cleaning is complete, the water purification control module can control the activation of the second heating element 2.10.

[0118] Furthermore, considering the arrangement of the second heating element 2.10 and the steam generator 3, it is difficult for the water in the first water outlet pipe 2.3 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 includes: a first portion connected to the second water outlet pipe 2.4, a second portion connected to the third water outlet pipe 2.8, and a third portion disposed between the first and second portions. A water pump 6 is provided in the third portion of the first water outlet pipe 2.3. The water pump 6 is configured to pump water from the filter group 2.1 and deliver it to the second portion of the first water outlet pipe 2.3.

[0119] When a water purification control module is provided, 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 status. When steam cleaning and hot filtered water production are being performed as described above, the water purification control module simultaneously controls water pump 6 to be on; when steam cleaning and hot filtered water production are not being performed, the water purification control module simultaneously controls water pump 6 to be off.

[0120] It should be 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, one-way valve 4, first high-pressure switch 2.7, second high-pressure switch 2.11, first heating element 9, second heating element 2.10, water pump 6, etc. described in any of the above embodiments are all commonly used devices in kitchen equipment. Based on the above description of this application, those skilled in the art can directly select these devices from the existing technology to implement the technical solution of this application. Therefore, in order to make this application more concise and clear to reflect the technical solution that makes a creative contribution to the existing technology, the specific structure of the above devices will not be described in detail.
