Therefore, in the prior art, a composite sink system integrating a water purification unit and a sink structure is provided, and multi-stage filtration modules are arranged to realize the purification treatment of drinking water.

[0003] In the prior art, the sink system mainly forms two different self-cleaning structures through two water sources: one is to directly use untreated municipal water, and the other is to use recycled purified water after primary filtration for flushing. However, long-term use observation shows that in the high-temperature and high-oil-smoke environment of the kitchen, the above two self-cleaning structures often cannot achieve satisfactory cleaning effect, and the sink system is prone to composite pollution problems such as microbial breeding and oil stain adhesion during long-term use in the kitchen. Especially, the stubborn stains formed on the inner wall of the sink, the drain outlet and the pipe joint part are more likely to cause health and safety hazards, which seriously affects the user experience.

[0024] The drainage pipe is hollow to form a drainage cavity inside, and the pipe wall is provided with an inlet and an outlet for the drainage cavity to communicate with the space outside the drainage pipe.

[0025] The water outlet end of the second water outlet branch pipe is in communication with the inlet, and the outlet is in communication with the steam inlet.

[0026] Further as a preferred solution, the steam inlet is disposed close to the tank opening of the cleaning tank, and the inner wall of the cleaning tank is protrusively formed with a connecting wall located above the steam inlet.

[0027] The end of the connecting wall away from the inner wall of the cleaning tank has a downwardly extending flow guide wall configured to direct steam entering the cleaning tank from the steam inlet to the inner wall of the cleaning tank below the steam inlet.

[0049] The present invention is specifically described below with reference to the embodiments:

[0050] Example 1:

[0051] The water tank system 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.

[0052] The sink 1 is also generally provided with a tap 1.3 for supplying tap water into the washing tank 1.11.

[0053] After the sink 1 is used (for example, for washing articles in the washing tank 1.11), tap water is supplied into the washing tank 1.11 through the tap 1.3 to flush the sink 1, especially the washing tank 1.11, to avoid dirt accumulation and bacterial growth. However, when the sink 1 is used for a long time in the kitchen, it is found that, for the kitchen environment with heavy oil fume, the sink 1 is often contaminated with more oil stains due to direct adhesion of oil fume or washing of oil-stained articles, and the sink 1 contaminated with oil stains cannot be cleaned well by using tap water only, which causes the sink 1, especially the washing tank 1.11 and the drain pipe 1.2, to be contaminated with oil stains after a long time of use, thereby seriously affecting the user experience.

[0054] Therefore, in order to better clean the oil stains, the steam generator 3 is preferably used in the embodiment to convert tap water into steam and supply the steam into the washing tank 1.11 to better clean the oil stains, thereby solving the above problems.

[0055] However, it is found in actual use that there are often many impurities in tap water, and the impurities in the tap water can adversely affect the steam generator 3 when the tap water is directly supplied into the steam generator 3 to be converted into steam, which not only affects the formation of steam but also easily damages the steam generator 3, thereby reducing the service life of the steam generator 3.

[0056] Therefore, in the embodiment, a water purification unit for supplying water and filtering the supplied water is arranged, and the steam generator 3 and the corresponding pipeline are arranged according to the water purification unit, so that the oil stains in the washing tank 1.11 can be better cleaned, and the influence on the steam generator 3 is reduced, thereby prolonging the service life of the steam generator 3.

[0057] Specifically, as shown in FIG. 1, the water purification unit for supplying water and filtering the supplied water includes a filtering group 2.1 for filtering the supplied water and supplying the filtered water into a first water outlet pipeline 2.3, and a water inlet pipeline 2.2 for supplying water and supplying the supplied water into the filtering group 2.1. Figure 2 Specifically, as shown in FIG. 1, the water purification unit for supplying water and filtering the supplied water includes a filtering group 2.1 for filtering the supplied water and supplying the filtered water into a first water outlet pipeline 2.3, and a water inlet pipeline 2.2 for supplying water and supplying the supplied water into the filtering group 2.1.

[0058] Figure 2 ​As 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.

[0059] 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.

[0060] 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).

[0061] 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 a first water outlet branch pipe 2.31 and a second water outlet branch pipe 2.32, respectively. The first water outlet branch pipe 2.31 is connected to the sewage pipe 1.2, and the second water outlet branch pipe 2.32 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 sewage pipe 1.2 through the first water outlet branch pipe 2.31 and into the cleaning tank 1.11 through the second water outlet branch pipe 2.32.

[0062] The first water outlet pipe 2.3 is provided with: a steam generator 3 that converts water into steam and transmits the steam to two water outlet branches (i.e., a first water outlet branch 2.31 and a second water outlet branch 2.32) through the water outlet end of the first water outlet pipe 2.3; and a first control valve 2.12 that controls 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 sink system is actually installed and used, the water inlet pipeline 2.2 far away from one end of the filter group 2.1 is connected with the tap water pipeline. When steam cleaning is needed for the cleaning tank 1.11:

[0064] By opening the first control valve 2.12 to make the first water outlet pipeline 2.3 in an open state, connecting the steam generator 3 with the power supply, and opening the steam generator 3, tap water enters the filter group 2.1 for filtration to form filtered water, the filtered water flows into the steam generator 3 through part of the first water outlet pipeline 2.3, is converted into steam by the steam generator 3, and flows to the first water outlet pipeline 2.3 through another part of the first water outlet pipeline 2.3, and then flows into the drain pipe 1.2 through the first water outlet branch pipe 2.31 and into the cleaning tank 1.11 through the second water outlet branch pipe 2.32 to clean the inner wall of the cleaning tank 1.11 and the drain pipe 1.2.

[0065] When the first control valve 2.12 is closed to make the first water outlet pipeline 2.3 in a closed state, and the steam generator 3 is closed, the steam cleaning is stopped.

[0066] The sink system capable of steam cleaning the cleaning tank 1.11 and the drain pipe 1.2 can direct high-temperature steam to the cleaning tank 1.11 and the drain pipe 1.2 to better clean oil stains in the cleaning tank 1.11 and the drain pipe 1.2, improve the cleanliness of the sink 1, and provide a better user experience.

[0067] In addition, in the above scheme, the filtered water is used as the water source of the steam generator 3, which can better prevent impurities in tap water from affecting the steam generator 3 and improve the long-term service life of the steam generator 3.

[0068] In the above scheme, the first control valve 2.12 and the steam generator 3 can be directly controlled by manual operation to realize the steam cleaning steps, but the operation is relatively complicated.

[0069] In order to be convenient to operate, in the embodiment, the water purification unit is preferably provided with a water purification control module for electrical connection with the power supply. The steam generator 3 is electrically connected to the water purification control module, the water purification control module supplies power to the steam generator 3 and controls the steam generator 3 to be turned on or off. The first control valve 2.12 is an electromagnetic valve for controlling the opening and closing of the first water outlet pipeline 2.3, and is electrically connected to the water purification control module. The water purification control module controls the first control valve 2.12 to open / close the first water outlet pipeline 2.3.

[0070] Meanwhile, a switch structure electrically connected to the water purification control module is arranged, which is configured to control the steam generator 3 and the first control valve 2.12 to be opened synchronously to form steam to clean the cleaning tank 1.11 as described above, and to control the steam generator 3 and the first control valve 2.12 to be closed synchronously.

[0071] In one form, the switch structure can include a cleaning opening key and a cleaning closing key arranged on the water tank 1 or the water purification unit. The cleaning opening key 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 be opened synchronously, and the cleaning closing key 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 be closed synchronously.

[0072] On the basis of the above-mentioned scheme, the water supply pipeline 2.1a can further be provided with a booster pump 2.1f for boosting water in the pipeline and delivering the boosted water to the first water outlet pipeline 2.3, and a reverse osmosis filter core 2.1c for receiving water output by the booster pump 2.1f, filtering the water through reverse osmosis, and then delivering the filtered water to the first water outlet pipeline 2.3. The reverse osmosis filter core 2.1c has a waste water pipe 2.1d for discharging waste water in the filtering process, and the waste water pipe is provided with a waste water control valve 2.1e for controlling the opening / closure of the waste water pipe (by controlling the opening / closure of the waste water control valve 2.1e, the opening / closure of the waste water pipe 2.1d is controlled). When steam cleaning is required as described above, the booster pump 2.1f and the waste water control valve 2.1e are opened 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, the water purification control module supplies power to the booster pump 2.1f and controls the opening / closure of the booster pump 2.1f; the waste water control valve 2.1e is an electromagnetic valve for controlling the opening / closure of the waste water pipe 2.1d, and is electrically connected to the water purification control module, which controls the opening / closure of the waste water pipe 2.1d by controlling the opening / closure of the waste water control valve 2.1e.

[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] Among them, for the cleaning of the cleaning tank 1.11:

[0078] The outlet end of the second water outlet branch pipe 2.32 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.

[0079] Based on this, in this embodiment, as shown in the attachedFigure 4 to the accompanying Figure 5 As shown in the accompanying drawings, the tank body 1.1 of the present embodiment is provided with: a steam inlet 1.12 located at the side wall of the cleaning tank 1.11; the steam inlet 1.12 is a through-hole structure provided at 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.

[0080] At the same time, the outer periphery of the tank body 1.1 is also provided with: a drainage pipe 8 located outside the cleaning tank 1.11. The drainage pipe 8 is internally formed with a drainage cavity 8.1 in a hollow manner, and the pipe wall is provided with: an inlet 8.2 for connecting the drainage cavity 8.1 with the space outside the drainage pipe 8, and an outlet 8.3 for connecting the drainage cavity 8.1 with the space outside the drainage pipe 8; the outlet end of the second water outlet branch pipe 2.32 is in communication with the inlet 8.2, and the outlet 8.3 is in communication with the steam inlet 1.12. So that: after the steam is formed as described above, the steam in the second water outlet branch pipe 2.32 can enter the drainage cavity 8.1 of the drainage pipe 8 through the inlet 8.2, flow through the drainage cavity 8.1, and then flow to the steam inlet 1.12 from the outlet 8.3, and finally flow into the cleaning tank 1.11 from the steam inlet 1.12, to clean the inside of the cleaning tank 1.11.

[0081] The above scheme 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; however, it cannot better clean the oil accumulation area of the cleaning tank 1.11, i.e. the inner wall of the cleaning tank 1.11.

[0082] Therefore, as a further improvement, in the present embodiment, as shown in the accompanying drawings, the steam inlet 1.12 is arranged close to the opening of the cleaning tank 1.11, and the inner wall of the cleaning tank 1.11 is formed with: a 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 flow 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 will flow along the flow guide wall 1.11b and enter the cleaning tank 1.11 from the steam inlet 1.12, and then flow along the inner wall of the cleaning tank 1.11 to the bottom of the cleaning tank 1.11, and finally flow out from the bottom of the cleaning tank 1.11. Figure 4 and 5 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.

[0083] 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.

[0084] Based on this, in this embodiment, as shown in the attached Figure 4 and 5 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).

[0085] 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.

[0086] 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.

[0087] In this embodiment, as shown in the attached Figure 4 and 5As shown, preferably, the first heating member 9 is clamped between the drain pipe 8 and the tank body 1.1, so that the two side surfaces of the first heating member 9 are respectively in contact with the drain pipe 8 and the tank body 1.1. That is, one side surface of the first heating member 9 is in contact with the drain pipe 8, and the other side surface is in contact with the tank body 1.1. In this way, when the first heating member 9 is in operation, it not only transfers part of the heat to the drain pipe 8 to improve the cleaning effect as described above, but also transfers part of the heat to the tank body 1.1 to directly heat the tank body 1.1. By heating the tank body 1.1, the sidewall of the cleaning tank 1.11 is heated, and the oil stains can be more easily separated from the heated cleaning tank 1.11, thereby improving the energy utilization rate and further optimizing the steam cleaning effect. Moreover, by heating the tank body 1.1, the water in the cleaning tank 1.11 can be better evaporated after the steam cleaning is completed, thereby improving the dryness of the tank after the steam cleaning is completed, and further achieving a more satisfactory cleaning effect.

[0088] In the above scheme, the first heating member 9 can be independently controlled by switching. Alternatively, the first heating member 9 can be electrically connected to the clean water control module, and the clean water control module supplies power to the first heating member 9 and controls the switching of the first heating member 9. As described above, by the switching structure, when the clean water control module controls the steam cleaning, the clean water control module synchronously controls the first heating member 9 to be turned on; and when the clean water control module controls the end of the steam cleaning, the clean water control module synchronously controls the first heating member 9 to be turned off.

[0089] Further, as shown in the accompanying drawings, Figure 2 In the present embodiment, the first control valve 2.12 is preferably arranged at the portion of the second water outlet branch pipe 2.32 between the filter group 2.1 and the steam generator 3. In this way, when cleaning is not performed, the water pressure in the second water outlet branch pipe 2.32 can act on the first control valve 2.12 rather than the steam generator 3 for a long time, so that the steam generator 3 can be better protected.

[0090] For cleaning of the drain pipe 1.2:

[0091] The water outlet end of the first water outlet branch pipe 2.31 can be directly inserted into the drain pipe 1.2 to deliver steam into the drain pipe 1.2 when steam cleaning is performed. However, in this way, the oil stain accumulation position of the drain pipe 1.2, i.e., the inner wall of the drain pipe 1.2, cannot be well cleaned.

[0092] Based on this, in the present embodiment, as shown in the accompanying drawings, Figure 4 and 6As shown, the water tank assembly further comprises a steam guide pipe 5 which is at least partially arranged in the drain pipe 1.2. The steam guide pipe 5 is internally formed with a steam flow channel 5.1, and the pipe wall is provided with a steam inlet 5.2 and a steam outlet 5.3 which are connected with the space outside the steam guide pipe 5. The steam inlet 5.2 is connected with the water outlet end of the first water outlet branch pipe 2.31. The steam outlet 5.3 is arranged in the drain pipe 1.2 and faces the inner wall of the drain pipe 1.2.

[0093] In this way, when steam cleaning is performed as described above, steam is delivered from the first water outlet branch pipe 2.31 to the steam inlet 5.2, enters the steam flow channel 5.1 through the steam inlet 5.2, and is then delivered to the inner wall of the drain pipe 1.2 from the steam outlet 5.3 (as indicated by the dashed arrow in FIG. 2), so that the inner wall of the drain pipe 1.2 can be better cleaned and the cleaning effect can be improved. Figure 6

[0094] In some embodiments, the steam guide pipe 5 extends along the inner periphery of the drain pipe 1.2, and the steam outlet 5.3 is provided with a plurality of steam outlets 5.3 which are spaced apart along the inner periphery of the drain pipe 1.2, so that the drain pipe 1.2 can be better cleaned.

[0095] Further, the first water outlet branch pipe 2.31 can be further provided with a one-way valve 4 which allows steam to flow only from the steam generator 3 to the drain pipe 1.2. This can better prevent backflow of air in the drain pipe 1.2 to the steam generator 3 and damage the steam generator 3.

[0096] Embodiment Two

[0097] Based on the scheme of Embodiment One, it is further considered that when steam is generated by the steam generator 3 in real time and delivered to the cleaning tank 1.11 in real time, the cleaning effect may sometimes not be satisfactory.

[0098] Based on this, as shown in FIG. 3, the steam generator 3 is arranged outside the cleaning tank 1.11, and the steam is delivered to the cleaning tank 1.11 through a steam delivery pipe 6. Figure 3 ​As shown, in the direction from the water purification unit to the water outlet end of the first water outlet pipeline 2.3, specifically in the direction from the filter group 2.1 to the water outlet end of the first water outlet pipeline 2.3, the first water outlet pipeline 2.3 is sequentially provided with: a first control valve 2.12, a steam generator 3, and a pressure limiting structure 7 receiving the steam output by the steam generator 3 and releasing the steam to the cleaning tank 1.11 when the received steam reaches a limited pressure value. The steam is output to the cleaning tank 1.11 after the pressure of the steam reaches the limited value, which can on the one hand make the steam delivered to the cleaning tank 1.11 and the blowdown pipe 1.2 have a certain pressure, so as to better impact and clean the oil stains and improve the cleaning effect of the single-point area; on the other hand, the steam delivered to the cleaning tank 1.11 and the blowdown pipe 1.2 can be delivered farther in the cleaning tank 1.11 and the blowdown pipe 1.2 under the push of a certain degree of high pressure, so that more areas in the cleaning tank 1.11 and the blowdown pipe 1.2 can be cleaned by the steam, thereby improving the cleaning effect of the overall area.

[0099] Specifically, as shown in the accompanying drawings, Figure 3 The pressure limiting structure 7 in the embodiment includes: a pressure chamber 7.1, a pressure sensor 7.3, and a third control valve 7.2.

[0100] Specifically, the pressure chamber 7.1 is arranged at the portion of the first water outlet pipeline 2.3 between the steam generator 3 and the water outlet end of the first water outlet pipeline 2.3, and has a steam storage cavity 7.11 therein. One end of the steam storage cavity 7.11 is in communication with the steam outlet of the steam generator 3 through a portion of the first water outlet pipeline 2.3 (the pipeline of the first water outlet pipeline 2.3 between the pressure chamber 7.1 and the steam generator 3); the other end is in communication with the water outlet end of the first water outlet pipeline 2.3 through another portion of the first water outlet pipeline 2.3 (the pipeline of the first water outlet pipeline 2.3 between the pressure chamber 7.1 and the water outlet end of the first water outlet pipeline 2.3), and is in communication with the two water outlet branch pipes, so that the steam output by the steam generator 3 can be input into the steam storage cavity 7.11 and enter the cleaning tank 1.11 and the blowdown pipe 1.2 through the steam storage cavity 7.11. The pressure sensor 7.3 is arranged in the steam storage cavity 7.11 and monitors the air pressure in the steam storage cavity 7.11. The third control valve 7.2 is arranged at the portion of the first water outlet pipeline 2.3 between the pressure chamber 7.1 and the water outlet end of the first water outlet pipeline 2.3, and is an electromagnetic valve for controlling the opening / closure of the first water outlet pipeline 2.3 (by controlling the opening / closure of the third control valve 7.2, the opening / closure of the first water outlet pipeline 2.3 is controlled).

[0101] Furthermore, 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 system 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 steam storage chamber 7.11. Simultaneously, the pressure sensor 7.3 monitors the pressure within the steam storage 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.

[0102] When pressure sensor 7.3 detects that the pressure in steam storage chamber 7.11 exceeds a specified pressure, the pressure limiting control module opens third control valve 7.2, allowing the accumulated steam to be transported to cleaning tank 1.11 and drain pipe 1.2 to clean the oil. When cleaning is complete, third control valve 7.2 closes.

[0103] 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.

[0104] Example 3:

[0105] 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.

[0106] Based on this, as attached Figure 7 As shown in FIG8 , 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.

[0107] 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.

[0108] When the second control valve 2.6 is opened, the first water outlet 2.5 outputs filtered water, which can be used for cleaning or cooking.

[0109] 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

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] Embodiment Four:

[0115] Based on the first embodiment or the second embodiment or the third embodiment, in order to make the sink system more suitable for the use requirements of the kitchen.

[0116] As shown in FIG. 8, the first water outlet 2.5 is arranged on the side wall of the sink 2.2, and the second water outlet pipeline 2.4 is arranged on the bottom wall of the sink 2.2. Figure 7 ​Or 8, the first water outlet pipeline 2.3 has a part between the first control valve 2.12 and the filter group 2.1, and the third water outlet pipeline 2.8 is also communicated with the part; one end of the third water outlet pipeline 2.8 away from the first water outlet pipeline 2.3 is communicated with the second water outlet faucet 2.9; and the third water outlet pipeline 2.8 is provided with a second heating member 2.10 for heating the water flowing in the third water outlet pipeline 2.8 (the second heating member 2.10 can be an electric heating member, that is, a member with an electric heating structure such as an electric heating wire inside, which can heat when powered on and does not heat when powered off).

[0117] At this time, when there is no second control valve 2.6, booster pump 2.1f and reverse osmosis filter core 2.1c, the second water outlet faucet 2.9 is opened and the second heating member 2.10 is opened, and the second water outlet faucet 2.9 can output hot filtered water filtered by the first water purification filter core 2.1b and the second water purification filter core 2.1g for cleaning or cooking.

[0118] When there is a second control valve 2.6, the second water outlet faucet 2.9, the second heating member 2.10 and the second control valve 2.6 are opened, and the second water outlet faucet 2.9 can output hot filtered water filtered for cleaning or cooking.

[0119] At this time, in order to be more convenient to make water through the second water outlet faucet 2.9, as shown in the accompanying drawings Figure 5 As shown, the third water outlet pipeline 2.8 has a part between the second heating member 2.10 and the second water outlet faucet 2.9, and the part is provided with a second high-pressure switch 2.11 configured to detect the water pressure between the second high-pressure switch 2.11 and the second water outlet faucet 2.9.

[0120] The second heating member 2.10 is electrically connected to the water purification control module, and the water purification control module supplies power to the second heating member 2.10 and controls the opening / closing of the second heating member 2.10; at the same time, the second control valve 2.6 and the second high-pressure switch 2.11 are 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 second high-pressure switch 2.11 and control whether the second water outlet faucet 2.9 outputs water according to the water pressure value.

[0121] 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 communicated with 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 second high-pressure switch 2.11 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, the second heating member 2.10 to open, and the second water outlet faucet 2.9 to output hot filtered water.

[0122] 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.

[0123] 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.

[0124] Furthermore, in this embodiment, as shown in the attached Figure 9 As shown, 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.

[0125] 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.

[0126] 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.

[0127] It should be further noted that the steam generator 3, the first control valve 2.12, the second control valve 2.6, the third control valve 7.2, the first water purification filter 2.1b, the second water purification filter 2.1g, the reverse osmosis filter 2.1c, the waste water control valve 2.1e, the booster pump 2.1f, the one-way valve 4, the first high-pressure switch 2.7, the second high-pressure switch 2.11, the first heating element 9, the second heating element 2.10, the water pump 6, etc. described in any of the above embodiments are all commonly used devices in kitchen equipment, and those skilled in the art can directly select these devices in the prior art according to the above description of the present application to realize the technical solutions of the present application.
