Description

Technical Field

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

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

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

[0025] The second control valve and the first high-pressure switch are both electrically connected to the control module, and the control module is configured to receive the water pressure value detected by the first high-pressure switch and control whether the first faucet dispenses water based on the water pressure value.

[0026] As a further preferred embodiment, the first outlet pipe has a portion located between the first control valve and the filter assembly, and this portion is also connected to a third outlet pipe;

[0027] The end of the third water outlet pipe that is furthest from the first water outlet pipe is connected to the second water outlet faucet;

[0038] The present invention will be further described below with reference to the accompanying drawings:

[0043] Figure 5 A schematic diagram of the overall pipeline structure for installing multiple water taps. Detailed Implementation

[0044] The present invention will be specifically illustrated below with reference to embodiments:

[0045] Example 1:

[0046] The sink assembly includes a sink 1; wherein the sink 1 includes a tank body 1.1 made of multiple metal materials, as shown in the attached figure. Figure 1 As shown, the tank 1.1 has an upward-facing cleaning tank 1.11, and also includes a drain pipe 1.2 connected to the tank 1.1 and used to drain the liquid from the cleaning tank 1.11. Specifically, the bottom wall of the cleaning tank 1.11 is provided with an outlet for draining the liquid from the cleaning tank 1.11. The upper end of the drain pipe 1.2 is connected to the outlet, and the lower end is generally connected to the building's sewage pipe, so that the liquid in the cleaning tank 1.11 can be discharged from the drain pipe 1.2 and discharged into the building's sewage pipe.

[0047] The tank body 1.1 is generally also equipped with a tap faucet 1.3 for delivering tap water to the cleaning tank 1.11.

[0048] After use (e.g., washing items in the washing tub 1.11), tap water is supplied to the washing tub 1.11 via the tap 1.3 to rinse the sink 1, especially the washing tub 1.11 and the drain pipe 1.2, to prevent the accumulation of impurities and the growth of bacteria. However, when the sink 1 is used in the kitchen for a long time, it is found that in the heavy oily environment of the kitchen, the sink 1 often accumulates a lot of grease due to the direct adhesion of grease or the washing of oily items. Simply using tap water is often insufficient to clean the grease-covered sink 1. As a result, after prolonged use, the sink 1, especially the drain pipe 1.2, is prone to grease buildup and blockage, leading to obstructed and poor drainage, which seriously affects the user experience.

[0049] Therefore, in order to better clean oil stains, this embodiment preferably uses a steam generator 3, which converts tap water into steam and transports it to the drain pipe 1.2 to better clean oil stains and solve the above problems.

[0050] However, in actual use, it was found that tap water often contains a lot of impurities. Directly supplying tap water to the steam generator 3 to convert it into steam can easily have a negative impact on the steam generator 3. This not only affects the steam generation effect but also easily damages the steam generator 3 and reduces its service life.

[0051] Based on this, this embodiment is provided with a water purification module that supplies water in and filters the inflowing water, and a steam generator 3 and corresponding pipelines are provided according to the water purification module, so as to: better clean the oil stains on the drain pipe 1.2 while reducing the impact on the steam generator 3, so that the steam generator 3 has a longer service life.

[0052] Specific details are attached. Figure 2 As shown, this embodiment is provided with a water purification module that supplies water in and filters the inflowing water. It includes a filter group 2.1 that filters the inflowing water and delivers the filtered water to the first outlet pipe 2.3, and an inlet pipe 2.2 that supplies water in and delivers the inflowing water into the filter group 2.1.

[0053] To be precise, as shown in the appendix Figure 2 As shown, the filter assembly 2.1 in this embodiment includes a water supply pipe 2.1a for water flow, with a filter inlet at one end for water to flow into the water supply pipe 2.1a and a filter outlet at the other end for water to flow out of the water supply pipe 2.1a; and the water supply pipe 2.1a is provided with at least a first water purification filter element 2.1b for filtering the water flowing into the water supply pipe 2.1a. The first water purification filter element 2.1b mainly includes: a water purification channel connected to the water supply pipe 2.1a for water to flow through, and a filter membrane disposed in the water purification channel for filtering the flowing water.

[0054] One end of the inlet pipe 2.2 is connected to the tap water pipe, and the other end is connected to the filter inlet of the water supply pipe 2.1a, so that tap water can enter the filter group 2.1 from the inlet pipe 2.2 for filtration. At the same time, the water purification module is connected to the first outlet pipe 2.3 for the filtered water to flow out; that is, the filter outlet of the water supply pipe 2.1a is connected to the first outlet pipe 2.3, so that the water filtered by the filter group 2.1 can be discharged from the first outlet pipe 2.3.

[0055] To improve filtration efficiency, see attached... Figure 2As shown, other filter structures can also be installed in the water supply pipe 2.1a, such as a second water purification filter 2.1g (the second water purification filter 2.1g mainly includes: a water purification channel connected to the water supply pipe 2.1a for water to flow through, and a filter membrane installed in the water purification channel for filtering the flowing water, and the filter membrane of the second water purification filter 2.1g and the filter membrane of the first water purification filter 2.1b can be configured differently according to requirements).

[0056] 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 drain pipe 1.2 so that the fluid in the first water outlet pipe 2.3 can be input into the drain pipe 1.2; and the first water outlet pipe 2.3 is provided with: a steam generator 3 that converts water into steam and delivers steam to the drain pipe 1.2, and a first control valve 2.12 that controls the opening / closing of the first water outlet pipe 2.3 (by controlling the opening / closing of the first control valve 2.12, the opening / closing of the first water outlet pipe 2.3 is controlled).

[0057] When the sink assembly is actually installed and used, the end of the water inlet pipe 2.2 furthest from the filter assembly 2.1 is connected to the tap water pipe. When steam cleaning of the drain pipe 1.2 is required:

[0058] By opening the first control valve 2.12 to ensure the first outlet pipe 2.3 is unobstructed, the steam generator 3 is connected to the power supply and turned on. Tap water then enters the filter group 2.1 through the inlet pipe 2.2 for filtration to form filtered water. This filtered water flows into the steam generator 3 through a portion of the first outlet pipe 2.3, where it is converted into steam. The steam then flows into the drain pipe 1.2 through another portion of the first outlet pipe 2.3 to perform steam cleaning of the drain pipe 1.2.

[0059] Closing the first control valve 2.12 to close the first water outlet pipe 2.3 and shutting off the steam generator 3 will shut down the steam cleaning process.

[0060] The aforementioned sink assembly that can use steam to clean the drain pipe 1.2 can not only better clean the oil stains in the drain pipe 1.2, but also keep the drain pipe 1.2 unobstructed, reducing the possibility of blockage, and allowing the sink 1 to drain more smoothly after long-term use, thus providing a better user experience.

[0061] Moreover, the above scheme uses filtered water as the water source for the steam generator 3, which can better prevent impurities in tap water from having a negative impact on the steam generator 3 and improve the long-term service life of the steam generator 3.

[0062] In the above scheme, the first control valve 2.12 and the steam generator 3 can be directly controlled manually to achieve the above steam cleaning steps, but the operation is relatively cumbersome.

[0063] For ease of operation, in this embodiment, a control module for electrical connection to a power source is preferably included in the water purification module. The steam generator 3 is electrically connected to this control module, which supplies power to the steam generator 3 and controls its on / off switching. The first control valve 2.12 is a solenoid valve that controls the opening / closing of the first water outlet pipe 2.3. It is electrically connected to the control module, which controls the opening / closing of the first control valve 2.12 to control the opening / closing of the first water outlet pipe 2.3.

[0064] Meanwhile, a switch structure electrically connected to the control module is also provided. This switch structure is configured to: control the steam generator 3 and the first control valve 2.12 to open synchronously, so as to generate steam to clean the drain pipe 1.2 as described above; and also control the steam generator 3 and the first control valve 2.12 to close synchronously.

[0065] In one embodiment, the switch structure may include a cleaning start button and a cleaning stop button disposed on the water tank 1 or the water purification module. The cleaning start button is configured to be electrically connected to the control module and to control the steam generator 3 and the first control valve 2.12 to open synchronously; the cleaning stop button is configured to be electrically connected to the control module and to control the steam generator 3 and the first control valve 2.12 to close synchronously.

[0066] Based on the above scheme, the water supply pipeline 2.1a can also be equipped with: a booster pump 2.1f that pressurizes the water in the pipeline and delivers the pressurized water to the first outlet pipeline 2.3; and a reverse osmosis filter element 2.1c that receives the water output from the booster pump 2.1f, performs reverse osmosis filtration on the water, and then delivers it to the first outlet pipeline 2.3. The reverse osmosis filter element 2.1c has a wastewater pipe 2.1d that discharges wastewater from the filtration process. This wastewater pipe is equipped with a wastewater control valve 2.1e to control its opening / closing (by controlling the opening / closing of the wastewater control valve 2.1e, the opening / closing of the wastewater pipe 2.1d is controlled). When steam cleaning is required as described above, the booster pump 2.1f and the wastewater control valve 2.1e are turned on to produce filtered water.

[0067] When the water purification module is equipped with a control module, the booster pump 2.1f is electrically connected to the control module. The control module supplies power to the booster pump 2.1f and controls the booster pump 2.1f to open and close. The wastewater control valve 2.1e is a solenoid valve that controls the opening and closing of the wastewater pipe 2.1d. It is electrically connected to the control module. The control module controls the wastewater control valve 2.1e to open and close, thereby controlling the opening and closing of the wastewater pipe 2.1d.

[0068] At this time, the switch structure is configured to: control the steam generator 3, the first control valve 2.12, the booster pump 2.1f, and the wastewater control valve 2.1e to open synchronously, so as to generate steam to clean the drain pipe 1.2 as described above; and also control the steam generator 3, the first control valve 2.12, the booster pump 2.1f, and the wastewater control valve 2.1e to close synchronously. For example, the cleaning start button is configured to: be electrically connected to the control module and control the steam generator 3, the first control valve 2.12, the booster pump 2.1f, and the wastewater control valve 2.1e to open synchronously; the cleaning stop button is configured to: be electrically connected to the control module and control the steam generator 3, the first control valve 2.12, the booster pump 2.1f, and the wastewater control valve 2.1e to close synchronously.

[0069] In some embodiments, the water inlet pipe 2.2 may also be provided with a second control valve 2.6 to control the opening / closing of the water inlet pipe 2.2 (by controlling the opening / closing of the second control valve 2.6, the water inlet pipe 2.2 is controlled to be open / closed). This controls whether water enters the water purification module.

[0070] When the water purification module is equipped with a control module, the second control valve 2.6 is a solenoid valve that controls the opening / closing of the inlet pipe 2.2. It is electrically connected to the control module, which controls the wastewater control valve 2.1e to open / close the inlet pipe 2.2. The switching structure is configured to: control the second control valve 2.6, steam generator 3, first control valve 2.12, booster pump 2.1f, and wastewater control valve 2.1e to open synchronously, so as to generate steam to clean the drain pipe 1.2 as described above; and also control the second control valve 2.6, steam generator 3, first control valve 2.12, booster pump 2.1f, and wastewater control valve 2.1e to close synchronously. For example, the cleaning start button is configured to be electrically connected to the control module and to control the second control valve 2.6, steam generator 3, first control valve 2.12, booster pump 2.1f, and wastewater control valve 2.1e to open synchronously; the cleaning stop button is configured to be electrically connected to the control module and to control the second control valve 2.6, steam generator 3, first control valve 2.12, booster pump 2.1f, and wastewater control valve 2.1e to close synchronously.

[0071] In the above scheme, the steam generator 3 and the first control valve 2.12 can be installed in the first water outlet pipe 2.3 as needed. However, it is easy for the steam generator 3 to be always full of water, which poses a certain risk to the long-term use of the steam generator 3.

[0072] Therefore, as attached Figure 2As shown, in this embodiment, the first control valve 2.12 is preferably located in the portion of the first water outlet pipe 2.3 between the filter assembly 2.1 and the steam generator 3. This ensures that when cleaning is not performed, the water pressure in the first water outlet pipe 2.3 will act on the first control valve 2.12 rather than the steam generator 3, thus providing better protection for the steam generator 3.

[0073] Furthermore, the first outlet pipe 2.3 has a section located between the steam generator 3 and the drain pipe 1.2, which is equipped with a one-way valve 4 that allows steam to flow unidirectionally from the steam generator 3 to the drain pipe 1.2. This better prevents the airflow in the drain pipe 1.2 from flowing back into the steam generator 3 and causing damage to the steam generator 3.

[0074] Furthermore, the outlet end of the first water outlet pipe 2.3 can be directly inserted into the drain pipe 1.2 to deliver steam to the drain pipe 1.2 during steam cleaning. However, this method cannot effectively clean the oil accumulation areas of the drain pipe 1.2, i.e., the inner wall of the drain pipe 1.2.

[0075] Based on this, in this embodiment, as shown in the appendix Figure 3 and 4 As shown, the water tank assembly also includes a steam guide pipe 5, which is at least partially placed inside the drain pipe 1.2. The interior of the steam guide pipe 5 is hollowly formed with a steam guide channel 5.1, and the pipe wall is provided with a steam inlet 5.2 and a steam outlet 5.3 for the steam guide channel 5.1 to communicate with the external space of the steam guide pipe 5. The water outlet end of the first water outlet pipe 2.3 is connected to the steam inlet 5.2; the steam outlet 5.3 is placed inside the drain pipe 1.2 and is positioned towards the inner wall of the drain pipe 1.2.

[0076] Thus, when steam cleaning is performed as described above, steam is delivered from the first outlet pipe 2.3 to the steam inlet 5.2, enters the steam guide channel 5.1 through the steam inlet 5.2, and is then delivered from the steam outlet 5.3 to the inner wall of the drain pipe 1.2 (as shown in the attached diagram). Figure 4 (As shown by the dashed arrow in the middle), so as to better clean the inner wall of the drain pipe 1.2 and improve the cleaning effect.

[0077] In some embodiments, the steam pipe 5 extends along the inner circumference of the drain pipe 1.2; and several steam outlets 5.3 are provided, which are spaced apart along the inner circumference of the drain pipe 1.2 to better clean the drain pipe 1.2.

[0078] Example 2:

[0079] Based on the solution in Example 1, considering that steam cleaning may be used only once every few days or even weeks, using only the water purification module to supply water to the steam generator 3 results in a low overall cost-effectiveness of the product and fails to fully utilize the performance of the water purification module.

[0080] Based on this, as attached Figure 5 As shown, the first water outlet pipe 2.3 has a portion located between the first control valve 2.12 and the filter assembly 2.1, which is connected to the second water outlet pipe 2.4; the end of the second water outlet pipe 2.4 away from the first water outlet pipe 2.3 is connected to the first water faucet 2.5.

[0081] At this time, when the second control valve 2.6, booster pump 2.1f and reverse osmosis filter 2.1c are not in use, the first water outlet 2.5 is turned on, and the first water outlet 2.5 can output filtered water that has passed through the first water purification filter 2.1b and the second water purification filter 2.1g, which can be used for cleaning or cooking.

[0082] When the second control valve 2.6 is present, opening the first water outlet 2.5 and the second control valve 2.6 will allow the first water outlet 2.5 to output filtered water for washing or cooking.

[0083] At this point, in order to more conveniently produce water through the first water tap 2.5, as shown in the attached... Figure 5 As shown, a first high-pressure switch 2.7 is installed in the second water outlet pipe 2.4, which is configured to detect the water pressure between it and the first water outlet tap 2.5.

[0084] The second control valve 2.6 and the first high-pressure switch 2.7 are both electrically connected to the control module, and the control module is configured to receive the water pressure value detected by the first high-pressure switch 2.7 and control whether the first water tap 2.5 dispenses water based on the water pressure value.

[0085] When the first water tap 2.5 is opened, the water path between the first high-pressure switch 2.7 and the first water tap 2.5 is connected to the outside air, thereby reducing the water pressure in that part of the water path. The control module is set with a predetermined water pressure value. When the water pressure value detected by the first high-pressure switch 2.7 and transmitted to the control module is lower than the predetermined water pressure value, the control module controls the second control valve 2.6 to open, and the first water tap 2.5 outputs filtered water.

[0086] When the first water tap 2.5 is closed, water accumulates in the water path between the first high-pressure switch 2.7 and the first water tap 2.5, causing the water pressure to increase. The first high-pressure switch 2.7 detects and transmits a water pressure value to the control module that is higher than the predetermined water pressure value. The control module then controls the second control valve 2.6 to close, and the first water tap 2.5 stops outputting filtered water.

[0087] When the booster pump 2.1f and reverse osmosis filter element 2.1c are also installed, and the first water outlet faucet 2.5 is opened, the control module synchronously controls the booster pump 2.1f and wastewater control valve 2.1e to open, so that the water purification module can produce filtered water and output it from the first water outlet faucet 2.5. When the first water outlet faucet 2.5 is closed, the control module synchronously controls the booster pump 2.1f and wastewater control valve 2.1e to close.

[0088] Example 3:

[0089] Based on Embodiment 1 or Embodiment 2, in order to make the sink assembly more adaptable to the usage needs of the kitchen.

[0090] As attached Figure 5 As shown, the first water outlet pipe 2.3 has a portion located between the first control valve 2.12 and the filter group 2.1, and this portion is also connected to the third water outlet pipe 2.8; the end of the third water outlet pipe 2.8 away from the first water outlet pipe 2.3 is connected to the second water outlet faucet 2.9; and the third water outlet pipe 2.8 is provided with a heating element 2.10 for heating the water flowing in the third water outlet pipe 2.8 (the heating element 2.10 can be an electric heating device, that is, a device with an electric heating structure such as an electric heating wire inside, which can heat when energized and does not heat when de-energized).

[0091] At this time, when the second control valve 2.6, booster pump 2.1f, and reverse osmosis filter 2.1c are not in use, the second water outlet 2.9 and heating element 2.10 are turned on. The second water outlet 2.9 can output hot filtered water that has been filtered by the first water purification filter 2.1b and the second water purification filter 2.1g, which can be used for cleaning or cooking.

[0092] When the second control valve 2.6 is present, opening the second water outlet 2.9, heating element 2.10, and second control valve 2.6 will allow the second water outlet 2.9 to output filtered, hot water for washing or cooking.

[0093] At this point, in order to more conveniently produce water through the second water tap 2.9, as shown in the attached... Figure 5 As shown, the third water outlet pipe 2.8 has a portion located between the heating element 2.10 and the second water outlet faucet 2.9. This portion is equipped with a second high-pressure switch 2.11, which is configured to detect the water pressure between it and the second water outlet faucet 2.9.

[0094] The heating element 2.10 is electrically connected to the control module, which supplies power to the heating element 2.10 and controls its opening and closing. Meanwhile, the second control valve 2.6 and the second high-pressure switch 2.11 are both electrically connected to the control module, which is configured to receive the water pressure value detected by the second high-pressure switch 2.11 and control whether the second faucet 2.9 dispenses water based on the water pressure value.

[0095] When the second water tap 2.9 is opened, the water path between the second high-pressure switch 2.11 and the second water tap 2.9 is connected to the outside air, thereby reducing the water pressure in that section. The control module has a preset water pressure value. When the water pressure value detected by the second high-pressure switch 2.11 and transmitted to the control module is lower than the preset value, the control module controls the second control valve 2.6 to open, the heating element 2.10 to activate, and the second water tap 2.9 to output hot filtered water.

[0096] When the second water tap 2.9 is closed, water accumulates in the water path between the second high-pressure switch 2.11 and the second water tap 2.9, causing the water pressure to increase. The second high-pressure switch 2.11 detects and transmits a water pressure value to the control module that is higher than the predetermined water pressure value. The control module then controls the second control valve 2.6 and the heating element 2.10 to close, and the second water tap 2.9 stops outputting filtered water.

[0097] When the booster pump 2.1f and reverse osmosis filter cartridge 2.1c are also installed, and the second water outlet faucet 2.9 is opened, the control module synchronously controls the booster pump 2.1f and wastewater control valve 2.1e to open, so that the water purification module can produce filtered water and output it from the second water outlet faucet 2.9. When the second water outlet faucet 2.9 is closed, the control module synchronously controls the booster pump 2.1f and wastewater control valve 2.1e to close.

[0098] Based on the above scheme, considering the arrangement of the heating element 2.10 and the steam generator 3, it is difficult for water in the first outlet pipe 2.3 to flow into the heating element 2.10 and the steam generator 3. Therefore, in order to improve the heating effect or steam conversion efficiency, as shown in the attached... Figure 5 As shown, in this embodiment, the first water outlet pipe 2.3 has: a first part connected to the second water outlet pipe 2.4, a second part connected to the third water outlet pipe 2.8, and a third part located between the first part and the second part; the third part of the first water outlet pipe 2.3 is provided with a water pump 6, which is configured to: draw water from the filter group 2.1 and deliver it to the second part of the first water outlet pipe 2.3.

[0099] When a control module is provided, the water pump 6 is electrically connected to the control module, which supplies power to the water pump 6 and controls its on / off operation. During steam cleaning and hot filtered water production as described above, the control module synchronously controls the water pump 6 to turn on; when steam cleaning and hot filtered water production are not performed, the control module synchronously controls the water pump 6 to turn off.

[0100] It should be further noted that the steam generator 3, first control valve 2.12, second control valve 2.6, first water purification filter element 2.1b, second water purification filter element 2.1g, reverse osmosis filter element 2.1c, wastewater control valve 2.1e, booster pump 2.1f, check valve 4, first high-pressure switch 2.7, second high-pressure switch 2.11, heating element 2.10, and water pump 6 described in any of the above embodiments are all commonly used devices in kitchen equipment.
