[0045] Reference below Figure 1-Figure 5 A water treatment device 1000 according to an embodiment of the present application is described.

[0046] like Figure 1 and Figure 2 As shown, according to the water treatment equipment 1000 of the first embodiment of the present application, the water treatment equipment 1000 includes: a shell 10, a water inlet pipeline 20, a water purification module, a first water supply pipeline 40, a second water supply pipeline 50 and a functional module 60.

[0047] Among them, a accommodating cavity 10a is formed in the shell 10; the water inlet pipeline 20 passes through the shell 10 and is connected to the water source; the water purification module is connected to the water inlet pipeline 20, the water purification module is used to purify water, and the water purification module is provided with a purified water outlet; one end of the first water supply pipeline 40 is connected to the purified water outlet, and the other end of the first water supply pipeline 40 is used to selectively directly discharge the purified water; one end of the second water supply pipeline 50 is connected to the purified water outlet; the functional module 60 is provided with a functional inlet, and the other end of the second water supply pipeline 50 is connected to the functional inlet, and the functional module 60 is used to heat, cool and / or make ice for the purified water; an electric valve 70 is arranged between the water inlet pipeline 20 and the water purification module, and a first switch 80 is arranged on the purified water outlet, and the first switch 80 is used to control the purified water outlet to be selectively connected with the first water supply pipeline 40 and the second water supply pipeline 50, and the electric valve 70 and the first switch 80 are arranged on the same side of the shell 10, and are arranged adjacent to the side plate 11 of the shell 10.

[0048] Specifically, the shell 10 has a accommodating cavity 10a, which can accommodate some other components of the water treatment device 1000 (such as a water purification module, a functional module 60, etc.). The shell 10 can provide installation positions for some other components of the water treatment device 1000, and play a good supporting, fixing and protecting role for some other components of the water treatment device 1000; the water inlet pipe 20 serves as the water source inlet of the water treatment device 1000, and is responsible for introducing external water into the water treatment device 1000; after the water flows through the water inlet pipe 20, it enters the water purification module, and after being purified by the water purification module, the water flows out from the water purification outlet of the water purification module to meet the drinking standard; a first water supply pipe 40 One end of the second water supply pipeline 50 is connected to the clean water outlet, and the other end is used to selectively and directly discharge the purified water so as to directly provide the user with purified drinking water; the functional inlet of the functional module 60 is directly connected to the clean water outlet, and the functional module 60 can perform at least one of heating, cooling and ice-making on the purified water, and integrate at least one of the heating, cooling and ice-making functions inside the water treatment equipment 1000 without connecting additional external equipment; one end of the second water supply pipeline 50 is connected to the clean water outlet, and the other end is connected to the functional inlet of the functional module 60, so that the second water supply pipeline 50 can transport the purified water to the functional module 60 for further processing, such as heating, cooling or ice-making.

[0049] Since the water treatment device 1000 integrates the functional module 60, it is no longer necessary to install an independent pipeline machine. When hot water is needed, the purified water enters the functional module 60, and the corresponding heating unit of the functional module 60 works to meet the user's immediate demand for hot water. When cold water is needed, the corresponding refrigeration unit in the functional module 60 works. For example, the water can be quickly cooled by the operation of the refrigeration compressor to provide cold water. When ice making is needed, the corresponding ice making unit in the functional module 60 works to convert the purified water into ice cubes, so that the water treatment device 1000 does not need to be additionally connected to a pipeline machine to achieve the functions of heating, cooling or ice making, thereby improving functionality. The first water supply pipeline 40 is connected to the clean water outlet and can be selectively drained, which can provide domestic water for washing vegetables, washing dishes, washing, etc., so that the water treatment device 1000 is no longer limited to providing drinking water, but can also meet some of the needs of household water.

[0050] An electric valve 70 is provided between the water inlet pipeline 20 and the water purification module in the embodiment of the present application, which is used to control the water inlet waterway of the water treatment equipment 1000 as a whole, and ensure the precise regulation of the water flow; a first switch 80 is provided on the water purification outlet, and the first switch 80 can control the water purification outlet to selectively communicate with the first water supply pipeline 40 and the second water supply pipeline 50, so that the water treatment equipment 1000 can flexibly switch the waterway, realize the direct drinking or further treatment of the purified water, and control the on-off between the first water supply pipeline 40 and the second water supply pipeline 50 and the water purification outlet by the first switch 80, and can also protect the internal components of the water treatment equipment 1000 from high pressure damage, and improve the working safety and durability of the internal components of the water treatment equipment 1000. The electric valve 70 and the first switch 80 are both arranged on the same side of the housing 10, and are arranged adjacent to the side plate 11 of the housing 10, so that the electric valve 70 and the first switch 80 are concentrated near the side plate 11, and the electric valve 70 and the first switch 80 are located on the peripheral side of other components in the housing 10.

[0051] According to the water treatment equipment 1000 of the present application, the electric valve 70 and the first switch 80 can be concentrated near the side plate 11 by optimizing the layout of the electric valve 70 and the first switch 80 in the shell 10. When the electric valve 70 and the first switch 80 need to be maintained or replaced, the side plate 11 of the shell 10 can be removed to expose the electric valve 70 and the first switch 80 without removing many other components inside the shell 10. In this way, the integrity and safety of other components can be protected, and it is convenient for staff to quickly locate them. At the same time, it is also convenient for staff to have sufficient operating space during maintenance, thereby improving maintenance efficiency and convenience, and saving maintenance costs.

[0052] In addition, in some specific embodiments of the present application, the other end of the first water supply pipeline 40 is connected to the faucet 2000 or the pipeline machine, so that the user can use domestic water through the faucet 2000, or use drinking water through the pipeline machine.

[0053] like Figure 3-Figure 5 As shown, according to some embodiments of the present application, the water treatment device 1000 also includes: a water leakage probe 90, which is arranged in the accommodating chamber 10a, and the water leakage probe 90 is communicatively connected with the electric valve 70, and the water leakage probe 90 is suitable for detecting whether there is leaked water in the accommodating chamber 10a, wherein the electric valve 70 can selectively control the conduction state of the water inlet pipe 20 according to the detection state of the water leakage probe 90.

[0054] Specifically, the water leakage probe 90 can be set at the bottom of the accommodating chamber 10a. The water leakage probe 90 can detect whether there is a water leakage. There are multiple water path components inside the water treatment equipment 1000, such as a water purification module, a functional module 60, etc. During long-term use, water leakage may occur due to aging of components, sealing failure, etc. After a water leakage occurs, water will flow to the bottom of the accommodating chamber 10a. At this time, the water leakage probe 90 can be quickly detected. When the water leakage probe 90 detects a water leakage, it can generate an electrical signal to be transmitted to the electric valve 70. The electric valve 70 is set on the water inlet pipe 20. After receiving the electrical signal, it will control the conduction state of the water inlet pipe 20 according to the signal, and close the water inlet pipe 20 in time to cut off the water source. In this way, it is possible to effectively prevent water from continuing to leak, and avoid greater harm caused by leakage, such as damaging other components inside the water treatment equipment 1000, causing the floor to become damp and deformed, causing electrical short circuits and other safety hazards. The water treatment equipment 1000 is equipped with electronic or mechanical components that are sensitive to water. The cooperation of the electric valve 70 and the leakage probe 90 can cut off the water source when leakage occurs, reduce the contact time between water and internal components, and reduce the risk of component damage.

[0055] In addition, in some specific embodiments of the present application, the water leakage probe 90 is configured as a plurality of water leakage probes 90 arranged at intervals on the bottom wall of the accommodating chamber 10a. The plurality of water leakage probes 90 are distributed in different areas of the accommodating chamber 10a, so as to directly and quickly detect the water leakage in the corresponding area, and can further improve the timeliness of cutting off the water source when a water leakage occurs.

[0056] In some other specific embodiments of the present application, the water leakage probe 90 , the electric valve 70 , and the first switch 80 are disposed on the same side of the housing 10 and are disposed adjacent to the side plate 11 of the housing 10 .

[0057] like Figure 4As shown, according to some embodiments of the present application, the water treatment device 1000 also includes: an electric control board 100, which is communicatively connected to the electric valve 70, and the electric control board 100 has a capacitor, which is suitable for supplying power to the electric valve 70 to close the water inlet pipeline 20 when the power supply of the water treatment device 1000 is disconnected.

[0058] Specifically, the electric control board 100 can be used for the overall electric linkage control in the water treatment equipment 1000. The electric control board 100 can transmit an electric signal to the electric valve 70 to control the on / off state of the electric valve 70. The electric control board 100 has a capacitor. The electric control board 100 can charge the capacitor when working normally. When it is detected that the power supply of the water treatment equipment 1000 is disconnected, it can automatically switch to the capacitor power supply mode. The capacitor can provide additional power support for the electric valve 70, so that the electric valve 70 can be quickly driven to close the water inlet pipeline 20 at the moment of power failure, and the water source of the water treatment equipment 1000 can be cut off in time. If the water inlet pipeline 20 is still in the open state after the power supply of the water treatment equipment 1000 is disconnected, the pipeline in the water treatment equipment 1000 may be damaged due to excessive water pressure caused by continuous introduction of water source, and the components such as the pipeline may be damaged, and water accumulation inside the water treatment equipment 1000 may damage electronic components. In the embodiment of the present application, through the additional power supply of the capacitor, the electric valve 70 can be reliably closed during a power outage, thereby avoiding damage or water leakage accidents of the water treatment equipment 1000 caused by power interruption, and can effectively improve the safety and reliability of the water treatment equipment 1000 in emergency situations.

[0059] In some embodiments, the electrical control panel 100 is used for electrical linkage control within the water treatment equipment 1000. In addition to the power failure protection function, the electrical control panel 100 also integrates multiple other functions, such as water leakage detection, fault alarm, remote monitoring, etc., to improve the intelligence level of the equipment and optimize the user experience.

[0060] like Figure 3-Figure 5 As shown, according to some embodiments of the present application, the shell 10 has a front panel 12 and a front shell plate 13, the front panel 12 has an opening, the front shell plate 13 is arranged on the side of the front panel 12 facing the accommodating cavity 10a, the water purification module includes a filtering device, the filtering device has a filter shell 311 and a door body 312, a cavity open toward the front panel 12 is formed in the filter shell 311, and the open end of the cavity defines an opening, the cavity is suitable for accommodating a filter element, and the door body 312 is detachably arranged at the opening.

[0061] Specifically, the front panel 12 of the housing 10 has an opening, and the opening connects the accommodating chamber 10a with the outside. The front shell plate 13 is arranged on the side of the front panel 12 facing the accommodating chamber 10a, and the front shell plate 13 can protect the internal components of the housing 10. The filtering device of the water purification module is used to filter the water flowing into the water purification module to improve the water quality. The filtering device has a filtering housing 311, and a cavity is formed in the filtering housing 311. The cavity can be used to accommodate a filter element, etc. The filter element can be used to remove impurities, harmful substances, etc. in the water. The cavity is open toward the front panel 12, and the open end of the cavity defines an opening. The door body 312 is detachably arranged at the opening. When the door body 312 is connected to the filtering housing 311, the door body 312 covers the open end of the cavity to protect the filter element and other components in the cavity. When the door body 312 is removed, the open end of the cavity is opened. By setting the front shell plate 13 and the door body 312 to be detachable, it is convenient for users to regularly replace the filter element to maintain the long-term cleanliness of the filter element in the filtering device and ensure the reliable filtering effect of the filtering device.

[0062] like Figure 3-Figure 5 As shown, according to some embodiments of the present application, a magnet is provided on the door body 312, and a door-controlled switch 13b is provided on the front shell plate 13. The door-controlled switch 13b is communicated with the electric control board 100 and is suitable for detecting the opening and closing state of the door body 312 through the magnet. When the door-controlled switch 13b detects that the door body 312 is open, the electric control board 100 controls the electric valve 70 to close the water inlet pipe 20, and controls to cut off the power supply of the water treatment equipment 1000.

[0063] Specifically, a magnet (such as a magnet) is provided on the door body 312, and the magnet serves as a trigger element for detecting the opening and closing state of the door body 312. A door-controlled switch 13b (such as a magnet sensing switch) is provided at a position corresponding to the magnet of the door body 312 on the front shell 13. The door-controlled switch 13b can determine the opening and closing state of the door body 312 by detecting the presence of the magnet and the distance between the magnet and the magnet. When the door body 312 is in an open state or a disassembled state, the door-controlled switch 13b detects the open state and transmits the corresponding electrical signal to the electric control board 100 in real time. The electric control board 100 automatically controls the electric valve 70 to close the water inlet pipeline 20 and cuts off the power supply of the water treatment device 1000 according to the preset control logic. In this way, it can prevent the water from flowing out when changing the filter element, thereby effectively improving the safety, and no manual intervention by the user is required. The user does not need to worry about the safety problems caused by forgetting to close the front shell 13 and the door body 312, thereby improving the intelligence level and user experience of the water treatment device 1000.

[0064] like Figure 1 As shown, according to some embodiments of the present application, the filtering device includes: a first filtering device 31a, a second filtering device 31b and a third filtering device.

[0065] Among them, the first filter device 31a is provided with a first filter inlet and a first filter outlet, and the first filter inlet is connected to the water inlet pipe 20; the second filter device 31b is provided with a second filter inlet and a second filter outlet, and the second filter inlet is connected to the first filter outlet; the third filter device is provided with a third filter inlet and a third filter outlet, and the third filter device is arranged downstream of the second filter device 31b.

[0066] Specifically, the water inlet pipe 20 is used as the water source access end, which is responsible for introducing the raw water from the outside into the subsequent entire system. After the raw water enters, it first reaches the first filter device 31a. The first filter inlet and the first filter outlet of the first filter device 31a work together, and can use filter materials such as filter screens and filter cotton to effectively intercept large-volume particle impurities in the raw water, such as silt, large particles of colloid, etc., to lay a good foundation for the subsequent filtering process. The water that has been initially filtered then flows into the second filter device 31b. The second filter device 31b works to remove microorganisms, impurities, etc. in the medium retained in the second filter device 31b. The water that has been circulated and purified by the second filter device 31b flows to the third filter device, where it is filtered more finely to further ensure the purity of the water quality. Finally, the water that has been filtered layer by layer flows to the first water supply pipe 40 to be directly discharged and the second water supply pipe 50 to further flow to the functional module 60. Through the sequential action of these three-stage filtering devices, the water treatment equipment 1000 can provide users with high-quality, safe and reliable drinking water.

[0067] like Figure 1 As shown, according to some embodiments of the present application, the second filter device 31b is constructed as a reverse osmosis membrane filter element, and the water purification module includes: a booster pump 32, the booster pump 32 is provided with a booster pump 32 inlet and a booster pump 32 outlet, the booster pump 32 inlet is connected to the first filter outlet, and the booster pump 32 outlet is connected to the second filter inlet.

[0068] Specifically, the second filter device 31b uses a reverse osmosis membrane filter. The reverse osmosis membrane is a semi-permeable membrane with fine pores. The pore size is small, usually at the nanometer level. The characteristics of the reverse osmosis membrane enable the reverse osmosis membrane to effectively block most impurities, ions, bacteria and viruses, etc., and only allow water molecules to pass through, thereby achieving deep purification of the water. However, in order for water to be filtered smoothly through the reverse osmosis membrane, it is necessary to overcome certain resistance, because the filtration process of the reverse osmosis membrane is carried out against the natural osmosis direction. The pressure on the raw water side must be large enough to force water molecules to overcome the osmotic pressure and pass through the reverse osmosis membrane to reach the pure water side. The inlet of the booster pump 32 is connected to the first filter outlet. The booster pump 32 sucks in the water that has been preliminarily filtered by the first filter device 31a. Then, the booster pump 32 applies additional pressure to the water through the internal mechanical structure or electrical drive to increase the water pressure. The outlet of the booster pump 32 is connected to the second filter inlet, and the pressurized water is transported to the second filter device 31b. When water with sufficient pressure enters the reverse osmosis membrane filter, water molecules can pass through the reverse osmosis membrane more smoothly, while various impurities, ions, bacteria and viruses in the water are intercepted on the other side of the membrane. The pressure provided by the booster pump 32 accelerates the flow rate of water on the surface of the reverse osmosis membrane, and more water can be processed per unit time, which greatly improves the filtration efficiency. Sufficient pressure can also ensure the interception effect of the reverse osmosis membrane on impurities. The stable pressure provided by the booster pump 32 can ensure that the reverse osmosis membrane fully exerts its interception function, so that impurities, heavy metal ions, bacteria and viruses in the water are further intercepted, thereby obtaining purer water.

[0069] like Figure 1 As shown, according to some embodiments of the present application, when the first switch 80 detects that the first water supply pipeline 40 and / or the second water supply pipeline 50 is in an open state, the electric control board 100 is suitable for controlling the boosting pump 32 to open and controlling the electric valve 70 to open the water inlet pipeline 20.

[0070] Specifically, the first switch 80 is arranged at the outlet of the purified water, and is used to control the connection state between the outlet of the purified water and the first water supply pipeline 40 and the second water supply pipeline 50. When the first switch 80 detects that at least one of the current first water supply pipeline 40 and the second water supply pipeline 50 is in the open state, the electric control board 100 receives the state signal of the first switch 80, determines that water supply is needed, and then controls the electric valve 70 to open the water inlet pipeline 20 to introduce the raw water from the outside into the subsequent entire system, and also controls the booster pump 32 to open, to provide sufficient pressure for the water flow in the water purification module, and ensure that the water flow can smoothly pass through the reverse osmosis membrane filter (the second filter device 31b) and other subsequent modules. Through the coordinated work of the first switch 80 and the electric control board 100, the intelligent control of the electric valve 70 and the booster pump 32 can be realized, and it can be operated when water supply is needed, thereby improving the intelligence level and user experience of the water treatment equipment 1000. When the first water supply pipeline 40 and the second water supply pipeline 50 are both closed, the electric control board 100 receives the closing signal of the first switch 80 and can also control the electric valve 70 to close the water inlet pipeline 20 and control the booster pump 32 to stop running, thereby saving energy consumption and improving environmental protection.

[0071] like Figure 1 , Figure 4 as well as Figure 5 As shown, according to some embodiments of the present application, the functional module 60 includes a water tank 61, the water tank 61 has a functional inlet, and a water level monitoring component 62 is arranged in the water tank 61, and the water level monitoring component 62 is suitable for detecting the water level in the water tank 61; the water treatment equipment 1000 also includes a solenoid valve 110, the solenoid valve 110 is arranged in the second water supply pipeline 50, and the solenoid valve 110 can selectively control the water to flow from the water purification module to the water tank 61; wherein

[0072] The solenoid valve 110 is in communication connection with the water level monitoring component 62 . The solenoid valve 110 detects the water level in the water tank 61 according to the water level monitoring component 62 and can selectively control the flow state of water from the water purification module to the water tank 61 .

[0073] Specifically, the water level monitoring component 62 can detect the water level in the water tank 61 in real time and accurately. When the water level in the water tank 61 drops to the minimum limit, or when the water level in the water tank 61 rises to the maximum limit, the water level monitoring component 62 can transmit this information to the solenoid valve 110 connected to it. The solenoid valve 110 is arranged in the second water supply pipeline 50, between the water purification module and the functional module 60. When receiving the low water level signal from the water level monitoring component 62, the solenoid valve 110 can be opened to allow the water purified by the water purification module to flow into the water tank 61, so as to replenish the water in time. When the water level rises to the preset high level, the water level monitoring component 62 sends a signal again, and the solenoid valve 110 is closed to stop the water supply. By controlling the water level, it can be ensured that the water level in the water tank 61 is always kept within a reasonable preset range, so as to achieve effective management of water resources, avoid the waste of water resources, and avoid the overflow and waste of water caused by excessive water filling of the water tank 61. At the same time, water level control also helps to save energy. When the water level in the water tank 61 is appropriate, the purification module suspends purification, which can reduce unnecessary energy consumption.

[0074] like Figure 1 As shown, according to some embodiments of the present application, the electric valve 70 has a rotatable valve core, and the valve core selectively rotates to control the opening and closing of the water inlet pipeline 20.

[0075] Specifically, a rotatable valve core is provided inside the electric valve 70, and the valve core can control the opening and closing of the water flow channel in the water inlet pipe 20 by rotation, thereby realizing the conduction or cutoff of water flow. The valve core can be connected to the driving mechanism (such as a motor) of the electric valve 70 to realize selective rotation through motor drive. When the electric control board 100 receives a signal that needs to open the water inlet pipe 20 (such as the user starts the water treatment device 1000 or the water treatment device 1000 enters the operating mode), the electric control board 100 sends an opening signal to the electric valve 70, and the motor of the electric valve 70 can drive the valve core to rotate to a specific angle, so that the water flow channel in the water inlet pipe 20 is fully opened, allowing water to pass through, and the water flow can smoothly pass through the water inlet pipe 20 into the water purification module; when the electric control board 100 receives a signal that needs to close the water inlet pipe 20 (such as the water treatment device 1000 enters the shutdown mode or detects an abnormal situation), the electric control board 100 sends a closing signal to the electric valve 70, and the motor of the electric valve 70 can drive the valve core to rotate to another specific angle, so that the water flow channel is completely closed, the water flow is cut off, and water is prevented from entering the water purification module. In the related art, the electric valve 70 uses sliding parts, which are prone to getting stuck or blocked due to the accumulation of impurities in the water. In the embodiment of the present application, a rotating valve core is used, which can effectively remove particles or dirt attached to the surface of the valve core and the wall of the water inlet pipe 20 through the rotation action, thereby achieving a self-cleaning effect, reducing the risk of clogging, and improving the anti-clogging performance of the electric valve 70.
