[0047] The present invention is specifically described below with reference to the embodiments:

[0048] Example 1:

[0049] The water tank device 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.

[0050] The tank body 1.1 is generally also provided with a tap 1.3 for conveying tap water to the cleaning tank 1.11.

[0051] 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.

[0052] Based on this, in order to better clean the oil stains, the steam generator 3 is preferably used in the embodiment, which converts tap water into steam and delivers it to the cleaning tank 1.11 to better clean the oil stains, thereby solving the above problems.

[0053] However, it is found in actual use that there are often many impurities in tap water. Directly delivering tap water to the steam generator 3 to convert it into steam, the impurities in the tap water can easily cause bad effects on the steam generator 3, which not only affects the formation of steam, but also easily damages the steam generator 3, reducing the service life of the steam generator 3.

[0054] Based on this, the water purification unit for water inflow and filtering of the inflowing water is provided in the embodiment, and the steam generator 3 and the corresponding pipeline are provided according to the water purification unit, so as to: better clean the oil stains in the cleaning tank 1.11 while weakening the influence on the steam generator 3, so that the steam generator 3 has a longer service life.

[0055] Specifically, as shown in the accompanying Figure 2 The water purification unit for water inflow and filtering of the inflowing water is provided in the embodiment, which includes: the filtering group 2.1 for filtering the inflowing water and delivering the filtered water to the first water outlet pipeline 2.3, and the water inlet pipeline 2.2 for water inflow and delivery of the inflowing water into the filtering group 2.1.

[0056] Specifically, as shown in the accompanying Figure 2 The filtering group 2.1 in the embodiment includes the water supply pipeline 2.1a for water circulation, which has the filtering water inlet at one end for water inflow into the water supply pipeline 2.1a and the filtering water outlet at the other end for water outflow from the water supply pipeline 2.1a; and at least the first water purification filter core 2.1b for filtering the water inflowing into the water supply pipeline 2.1a is provided in the water supply pipeline 2.1a. The first water purification filter core 2.1b mainly includes: the water purification flow channel connected to the water supply pipeline 2.1a for water flow, and the filtering membrane provided in the water purification flow channel for filtering the flowing water.

[0057] One end of the water inlet pipeline 2.2 is connected to the tap water pipeline, and the other end is connected to the filtering water inlet of the water supply pipeline 2.1a, so that the tap water can enter the filtering group 2.1 from the water inlet pipeline 2.2 for filtering. At the same time, the water purification unit is connected to the first water outlet pipeline 2.3 for filtered water outflow; that is, the filtering water outlet of the water supply pipeline 2.1a is connected to the first water outlet pipeline 2.3, so that the water filtered by the filtering group 2.1 can be discharged from the first water outlet pipeline 2.3.

[0058] In order to improve the filtering effect, as shown in the accompanyingFigure 2 As shown, other filter core structures can also be arranged in the water supply pipeline 2.1a, such as a second water purification filter 2.1g (the second water purification filter 2.1g mainly includes a water purification flow channel connected to the water supply pipeline 2.1a and through which water can flow, and a filter membrane arranged in the water purification flow channel and used to filter the water flowing therethrough, 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 arranged differently according to requirements).

[0059] Further, the water outlet end of the first water outlet pipeline 2.3 (i.e., the end of the first water outlet pipeline 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 pipeline 2.3 can be input into the cleaning tank 1.11; and the first water outlet pipeline 2.3 is provided with a steam generator 3 for converting water into steam and delivering the steam to the cleaning tank 1.11, and a first control valve 2.12 for controlling the opening / closure of the first water outlet pipeline 2.3 (by controlling the opening / closure of the first control valve 2.12, the opening / closure of the first water outlet pipeline 2.3 can be controlled).

[0060] When the steam cleaning of the cleaning tank 1.11 is needed, the first control valve 2.12 is opened to make the first water outlet pipeline 2.3 in an open state, the steam generator 3 is connected to a power source and is turned on. The tap water enters the filter group 2.1 through the water inlet pipeline 2.2 to be filtered 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 into the cleaning tank 1.11 through another part of the first water outlet pipeline 2.3 to clean the inner wall of the cleaning tank 1.11 by steam.

[0061] When the steam cleaning of the cleaning tank 1.11 is needed, the first control valve 2.12 is opened to make the first water outlet pipeline 2.3 in an open state, the steam generator 3 is connected to a power source and is turned on. The tap water enters the filter group 2.1 through the water inlet pipeline 2.2 to be filtered 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 into the cleaning tank 1.11 through another part of the first water outlet pipeline 2.3 to clean the inner wall of the cleaning tank 1.11 by steam.

[0062] When the steam cleaning of the cleaning tank 1.11 is needed, the first control valve 2.12 is opened to make the first water outlet pipeline 2.3 in an open state, the steam generator 3 is connected to a power source and is turned on. The tap water enters the filter group 2.1 through the water inlet pipeline 2.2 to be filtered 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 into the cleaning tank 1.11 through another part of the first water outlet pipeline 2.3 to clean the inner wall of the cleaning tank 1.11 by steam.

[0063] The sink device capable of using steam to clean the cleaning tank 1.11 not only can direct the high-temperature steam to the cleaning tank 1.11 to better clean the oil stains in the cleaning tank 1.11 and improve the cleanliness of the sink 1, but also has a better use experience.

[0064] Moreover, in the above scheme, the filtered water is used as the water source of the steam generator 3, which can better prevent the impurities in the tap water from affecting the steam generator 3 and improve the long-term service life of the steam generator 3.

[0065] 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 above steam cleaning step, but the operation is relatively complicated.

[0066] For convenient operation, the water purification unit can be provided with a water purification control module for electrical connection with a power supply in the embodiment. The steam generator 3 is electrically connected to the water purification control module, which supplies power to the steam generator 3 and controls the opening and closing of the steam generator 3. The first control valve 2.12 is an electromagnetic valve for controlling the opening and closing of the first water outlet pipeline 2.3, which is electrically connected to the water purification control module, which controls the opening and closing of the first water outlet pipeline 2.3.

[0067] Meanwhile, a switch structure electrically connected to the water purification control module is also provided, which is configured to control the steam generator 3 and the first control valve 2.12 to open 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 close synchronously.

[0068] In one form, the switch structure can include a cleaning opening key and a cleaning closing key provided on the sink 1 or the water purification unit. The cleaning opening key is electrically connected to the water purification control module and can control the steam generator 3 and the first control valve 2.12 to open synchronously, and the cleaning closing key is electrically connected to the water purification control module and can control the steam generator 3 and the first control valve 2.12 to close synchronously.

[0069] On the basis of the above scheme, the water supply pipeline 2.1a can also be provided with a booster pump 2.1f for boosting the 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 the water output by the booster pump 2.1f and filtering the water by reverse osmosis before delivering the 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 during the filtration process, and the waste water pipe is provided with a waste water control valve 2.1e for controlling the opening and closing of the waste water pipe 2.1d (by controlling the opening and closing of the waste water control valve 2.1e to control the opening and closing of the waste water pipe 2.1d). 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.

[0070] 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 booster pump 2.1f to turn on and off; the waste water control valve 2.1e is an electromagnetic valve for controlling the opening / closing of the waste water pipe 2.1d, which is electrically connected to the water purification control module, and the water purification control module controls the waste water control valve 2.1e to open / close the waste water pipe 2.1d.

[0071] At this time, the switch structure is configured to be able to control the steam generator 3, the first control valve 2.12, the booster pump 2.1f and the waste water control valve 2.1e to be turned on synchronously to form steam to clean the cleaning tank 1.11 as described above; also be able to control the steam generator 3, the first control valve 2.12, the third control valve 7.2, the booster pump 2.1f and the waste water control valve 2.1e to be turned off synchronously. For example, the cleaning on key is configured to be electrically connected to the water purification control module and to be able to control the steam generator 3, the first control valve 2.12, the booster pump 2.1f and the waste water control valve 2.1e to be turned on synchronously; the cleaning off key is configured to be electrically connected to the water purification control module and to be able to control the steam generator 3, the first control valve 2.12, the booster pump 2.1f and the waste water control valve 2.1e to be turned off synchronously.

[0072] In some embodiments, the water inlet pipeline 2.2 can also be provided with a second control valve 2.6 for controlling the opening / closing of the water inlet pipeline 2.2 (by controlling the second control valve 2.6 to be turned on / off to control the opening / closing of the water inlet pipeline 2.2). To control whether the water purification unit is watered.

[0073] When the water purification unit is provided with a water purification control module, the second control valve 2.6 is an electromagnetic valve for controlling the opening / closing of the water inlet pipeline 2.2, which is electrically connected to the water purification control module, and the water purification control module controls the waste water control valve 2.1e to open / close the water inlet pipeline 2.2. The switch structure is configured to be able to control the second control valve 2.6, the steam generator 3, the first control valve 2.12, the booster pump 2.1f and the waste water control valve 2.1e to be turned on synchronously to form steam to clean the cleaning tank 1.11 as described above; also be able to control the second control valve 2.6, the steam generator 3, the first control valve 2.12, the third control valve 7.2, the booster pump 2.1f and the waste water control valve 2.1e to be turned off synchronously. For example, the cleaning on key is configured to be electrically connected to the water purification control module and to be able to control the second control valve 2.6, the steam generator 3, the first control valve 2.12, the booster pump 2.1f and the waste water control valve 2.1e to be turned on synchronously; the cleaning off key is configured to be electrically connected to the water purification control module and to be able to control the second control valve 2.6, the steam generator 3, the first control valve 2.12, the booster pump 2.1f and the waste water control valve 2.1e to be turned off synchronously.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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 4As shown by the middle arrow, after flowing from the outlet 8.3 to the steam inlet 1.12, the steam will flow from the steam inlet 1.12 to collide with the connecting wall 1.11a and the guide wall 1.11b, and the guide wall 1.11b will guide the steam downward to the inner wall of the cleaning tank 1.11, so as to better clean the oil accumulation position of 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, through the arrangement of 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 the cleaning tank 1.11 is used to clean the object, so as to better reduce the possibility of blockage caused by the accumulation of water scale in the drainage cavity 8.1.

[0079] In the above scheme, the extension path and the extension length of the drainage pipe 8 are set according to the arrangement position of the steam inlet 1.12, and the arrangement position of the steam inlet 1.12 is set according to the cleaning demand. In order to clean more areas, the drainage pipe 8 often needs to be set relatively long, which causes the steam input into the drainage cavity 8.1 to easily condense, resulting in a large amount of condensed water existing in the drainage cavity 8.1. In turn, it causes the water scale to easily accumulate in the drainage cavity 8.1, which hinders the smooth flow of steam, and in turn, reduces the cleaning efficiency.

[0080] Based on this, in the present embodiment, as shown in Figs. 1 and 2, a first heating member 9 (which can be an electric heating member, i.e., a member having an electric heating structure such as an electric heating wire inside, which can be heated by being powered on and not heated by being powered off) can be further attached to the outer periphery of the drainage pipe 8. Figure 3 4 As shown in Figs. 1 and 2, a first heating member 9 (which can be an electric heating member, i.e., a member having an electric heating structure such as an electric heating wire inside, which can be heated by being powered on and not heated by being powered off) can be further attached to the outer periphery of the drainage pipe 8.

[0081] When steam cleaning is performed as described above, the first heating member 9 is powered on to heat the drainage pipe 8, which on the one hand can slow down the condensation of steam in the drainage cavity 8.1, reduce the possibility of blockage caused by the accumulation of water scale in the drainage cavity 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 relatively high temperature to better clean the oil stains, thereby improving the cleaning effect.

[0082] After the first heating member 9 is arranged as described above, if only one side of the first heating member 9 is attached to the drainage pipe 8, most of the heat generated by the first heating member 9 will be transferred to the air from the other side, causing excessive energy waste.

[0083] In the present embodiment, as shown in Figs. 1 and 2, a first heating member 9 (which can be an electric heating member, i.e., a member having an electric heating structure such as an electric heating wire inside, which can be heated by being powered on and not heated by being powered off) can be further attached to the outer periphery of the drainage pipe 8. Figure 3 4 ​​As 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 sink 1 after the steam cleaning is completed, and further having a more satisfactory cleaning effect.

[0084] 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 water purification control module, and the water purification 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 water purification control module controls the steam cleaning, the water purification control module synchronously controls the first heating member 9 to be turned on; and when the water purification control module controls the end of the steam cleaning, the water purification control module synchronously controls the first heating member 9 to be turned off.

[0085] 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 first water outlet pipeline 2.3 between the filter group 2.1 and the steam generator 3. In this way, when cleaning is not performed, the water pressure in the first water outlet pipeline 2.3 can act on the first control valve 2.12 rather than the steam generator 3 for a long time, so as to better protect the steam generator 3.

[0086] Embodiment Two:

[0087] Based on the scheme of embodiment one, it is further considered that when the steam generator 3 generates steam in real time and the steam is delivered into the cleaning tank 1.11 in real time, the cleaning effect may not be satisfactory sometimes.

[0088] Based on this, as shown in the accompanying drawings, Figure 5As shown, in the direction from the water purification unit to the cleaning tank 1.11, specifically in the direction from the filter group 2.1 to the cleaning tank 1.11, 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 one hand make the steam delivered to the cleaning tank 1.11 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 can be delivered farther in the cleaning tank 1.11 under the push of a certain degree of high pressure, so that more areas in the cleaning tank 1.11 can be cleaned by the steam and the cleaning effect of the overall area is improved.

[0089] Specifically, as shown in the accompanying drawings, Figure 5 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.

[0090] 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 cleaning tank 1.11, 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), and the other end is in communication with the cleaning tank 1.11 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 cleaning tank 1.11), 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 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 cleaning tank 1.11, 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).

[0091] 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 device 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.

[0092] 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.

[0093] 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.

[0094] Example 3:

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] Embodiment Four

[0105] Based on the first embodiment or the second embodiment or the third embodiment, in order to make the sink device more suitable for the use requirements of the kitchen.

[0106] 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 side wall of the sink 2.2. 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.)

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.
