Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a multifunctional water treatment system. Background Art

[0002] An ice purifier, also known as an ice-making water dispenser, is an appliance that has the functions of purifying water, dispensing water, making ice, and dispensing ice. Ice-making and water-drinking machines typically include an ice storage container for storing ice cubes. As ice cubes remain in the ice storage container for an extended period of time, they melt and form meltwater, which can easily breed bacteria and microorganisms. To promptly remove the meltwater, some ice-making and water-drinking machines are equipped with a cold water recovery device. For example, Chinese invention patent application CN118402704A discloses an ice-making and water-drinking machine comprising a cold water recovery device disposed within a cold water tank for accommodating a pure water cup, an ice making and water-making refrigerator, and an ice storage bin. The cold water recovery device includes a cold water tank. The bottom of the cold water tank is connected to a cold water pump interface and an ice making pump interface. The top of the cold water tank is connected to a water inlet, and an ice water drain extends into the cold water tank. The meltwater is discharged into the cold water tank through the ice water drain for storage.

The water purification module 100 can filter the raw water and produce drinkable pure water, and inject the pure water into the ice making module 200 through the first water inlet channel 101. The ice making module 200 makes ice cubes with pure water. Making ice with pure water can improve the quality of ice cubes and protect the health of users. More specifically, the water purification module 100 includes a first filter Component 120, filters raw water and produces pure water through the first filter component 120, the ice making module 200 includes a cold water tank 210 connected to the first filter component 120, the first water inlet channel 101 is connected between the pure water output end of the first filter component 120 and the cold water tank 210, and the pure water is diverted to the cold water tank 210 through the first water inlet channel 101. The cold water tank 210 can store pure water. As the pure water is placed in the cold water tank 210 for a longer time, bacteria, microorganisms and other substances are easily grown in the water, resulting in a decrease in water quality. Therefore, the water treatment system is provided with a first return channel 201 connected between the cold water tank 210 and the water purification module 100, and the water in the cold water tank 210 is diverted to the first filter component 120 for secondary filtration through the first return channel 201, so as to improve the water quality in the water treatment system, thereby improving the quality of ice cubes, further protecting user health, reducing water resource waste, and improving the utilization rate of pure water. Alternatively, the water inlet of the first filter assembly 120 can be directly connected to an external water source to input raw water, and the first return flow channel 201 can be connected to the flow channel between the external water source and the water inlet of the first filter assembly 120, and then the pure water requiring secondary filtration can be injected into the first filter assembly 120 through the water inlet of the first filter assembly 120. Alternatively, the first filter assembly 120 can be provided with multiple water inlets to respectively connect the external water source and the first return flow channel 201. Alternatively, the first filter assembly 120 can be a common multi-stage filter element, RO composite filter element, or other filter element capable of producing drinkable pure water.

[0028] Specifically, the water purification module 100 also includes a raw water flow channel 102 connected to the water inlet end of the first filter component 120, the raw water flow channel 102 can input raw water to the first filter component 120, the first return flow channel 201 is connected to the water inlet end of the first filter component 120 through the raw water flow channel 102, a first water pump 1021 is provided in the raw water flow channel 102, the concentrated water output end of the first filter component 120 is also connected to the concentrated water flow channel 103, and a concentrated water valve 1031 is provided in the concentrated water flow channel 103; in this embodiment, the raw water flow channel 102 is connected to the water inlet end of the first filter component 120, the raw water flow channel 102 can be connected to an external water source to input raw water to the first filter component 120, and the first return flow channel 201 is connected to the raw water pump 1021. The water flow channel 102 is connected so that the first return flow channel 201 is connected to the water inlet end of the first filter component 120, ensuring that the water in the cold water tank 210 can be guided to the first filter component 120 through the first return flow channel 201 for secondary filtration; in addition, raw water is pumped into the first filter component 120 through the first water pump 1021 to increase the flow rate of the raw water, thereby improving the water purification efficiency of the first filter component 120, and the concentrated water valve 1031 can control the on and off of the concentrated water flow channel 103; when the concentrated water valve 1031 is opened, the concentrated water formed when the first filter component 120 filters the raw water can flow directly to the outside through the concentrated water flow channel 103; when the concentrated water valve 1031 is closed, the discharge of concentrated water can be controlled, and the filter component can be protected when the system is shut down.

Alternatively, the first water pump 1021 may be a water pump with a valve, which controls the on / off flow of the raw water flow channel 102. When the water treatment system is not in use, closing the first water pump 1021 with the valve can restrict the flow of raw water from the raw water flow channel 102 to the first filter assembly 120. Alternatively, the concentrate valve 1031 may be a solenoid valve, a pneumatic valve, a hydraulic valve, or the like.

[0029] As a preferred embodiment of the present invention but not a limitation, the water purification module 100 further includes a raw water tank 110 connected to the raw water flow channel 102, and the first return flow channel 201 is connected to the raw water flow channel 102 through the raw water tank 110; specifically, the raw water tank 110 can be connected to an external water source and store raw water, and the raw water flow channel 102 is connected between the raw water tank 110 and the first filter component 120, and diverts the raw water in the raw water tank 110 to the first filter component 120 so that the first filter component 120 can filter the raw water and produce pure water, and the first return flow channel 201 is connected to the raw water tank 110. The water flow channel 102 is connected and diverts the water in the cold water tank 210 into the raw water tank 110, so that the water that needs secondary filtration can be stored in the raw water tank 110 first, and then diverted to the first filter component 120 through the raw water flow channel 102 for secondary filtration, thereby avoiding the first filter component 120 from being overloaded and easily failing. Moreover, when the amount of water in the cold water tank 210 is too large, the excess water can be first diverted to the raw water tank 110 through the first return flow channel 201 to avoid the excess water in the cold water tank 210 from flowing back along the first water inlet flow channel 101, thereby ensuring that the water treatment system can normally prepare pure water. In addition, optionally, at least part of the concentrated water flow channel 103 is arranged in the raw water tank 110, and the concentrated water flow channel 103 is independent of the raw water flow channel 102. A part of the concentrated water flow channel 103 is arranged outside the raw water tank 110 and connected to the concentrated water output end of the first filter component 120, and the other part is arranged in the raw water tank 110, which can reduce the volume of the water treatment system in actual application, and an independent pipe can be set in the raw water tank 110 for concentrated water to flow through. The independent pipe can be additionally set or directly formed by modifying the raw water tank 110 body to avoid contaminating the raw water when the concentrated water is output to the outside, thereby increasing the difficulty of water purification; optionally, the concentrated water flow channel 103 is connected between the raw water tank 110 and the concentrated water output end of the first filter component 120, and the concentrated water formed in the first filter component 120 is diverted to the raw water tank 110 through the concentrated water flow channel 103 for re-filtration to produce pure water for use, which is beneficial to reduce concentrated water discharge and increase pure water output.

A second return flow channel 204 is provided between the first ice outlet channel 202 and the cold water tank 210. Specifically, the second water inlet flow channel 203 is communicated between the cold water tank 210 and the ice-making assembly 220, and the pure water in the cold water tank 210 can be discharged into the ice-making assembly 220 through the second water inlet flow channel 203. The ice cubes are sent to the ice-making assembly 220 to be made into ice cubes, which can slide out to the outside along the first ice outlet channel 202 for use by users. Since ice cubes are easily accumulated in the first ice outlet channel 202, ice water will be formed in the first ice outlet channel 202 when the ice cubes melt.

When the storage time of the ice cubes is prolonged, ice water will be formed in the refrigerator 240 when the ice cubes melt. In order to clean the ice water in the refrigerator 240 in time, the third return flow channel 205 is set in the refrigerator 240 and the cold water tank 210. The melted water of the ice cubes can flow back directly from the inside of the refrigerator 240 to the inside of the cold water tank 210 along the third return flow channel 205 to avoid the growth of bacteria in the refrigerator 240 and the deterioration of the quality of the ice cubes. It can also improve the utilization rate of water and reduce the waste of water resources; further, a second filter component 2051 is set in the third return flow channel 205 along the water flow direction.

[0039] It should be noted that the above-mentioned specific settings of the hot water and normal temperature water output channels can be customized according to the actual needs of the user.

[0040] The utility model provides a multifunctional water treatment system, which has at least the functions of water purification, water output, ice making and ice output, as follows.

[0041] Water purification process: The raw water tank 110 can be connected to an external water source and store raw water. When the first water pump 1021 is started, the raw water is input to the first filter component 120 through the raw water flow channel 102, and then the raw water is filtered by the first filter component 120 to produce drinkable pure water. The pure water output end of the first filter component 120 is respectively connected to the first water inlet flow channel 101 and the second water inlet flow channel 203. When the first water inlet valve 1011 is opened and the second water inlet valve 1041 is closed, the pure water can flow along the first water inlet flow channel 101 to the ice-making module 200 for ice making; when the second water inlet valve 1041 is opened and the first water inlet valve 1011 is closed, the pure water can flow along the third water inlet flow channel 104 to the external pure water container 310 for direct output; in addition, when the concentrated water valve 1031 is opened, the concentrated water formed during filtration is output to the outside through the concentrated water flow channel 103. Optionally, when the first water inlet valve 1011 and the second water inlet valve 1041 are closed at the same time and the concentrated water valve 1031 is opened, the first filter component 120 can also use pure water for self-cleaning to improve the filtering efficiency of the first filter component 120.

[0042] Ice making and ice water output process: When the first water inlet valve 1011 is opened, pure water flows along the first water inlet channel 101 to the cold water tank 210, and the water in the cold water tank 210 flows to the ice making assembly 220 through the second water inlet channel 203 to make ice. The ice cubes made by the ice making assembly 220 can fall into the ice making refrigerator 240 for storage, and then the ice cubes can be output to the outside along the first ice outlet channel 202 or the second ice outlet channel 207. Among them, the ice cubes in the first ice outlet channel 202 are further crushed to form crushed ice and output by the ice crushing assembly 230, and the second ice outlet channel 207 can directly output whole ice; it should be noted that the whole ice can be output to the outside through the second ice outlet channel 207, or the user can manually take out the whole ice directly from the ice making refrigerator 240. In addition, in order to promptly clean up the melted ice water in the ice making refrigerator 240 and the first ice outlet channel 202, the cold water tank 210 is also connected to a second return flow channel 204 connected to the first ice outlet channel 202 and a third return flow channel 205 connected to the ice making refrigerator 240, so that the melted ice water can be recycled into the cold water tank 210 for secondary use, thereby improving water utilization. In addition, since the cold water tank 210 can simultaneously accommodate pure water at room temperature and melted ice water, the two types of water can be mixed to form pure water at a lower temperature. This lower temperature pure water can be directly output as ice water through the ice water output channel 206 for user use, thereby increasing the diversity of the water treatment system's functions and optimizing the user experience. Optionally, the cold water tank 210 has a heat preservation effect, which can keep the water inside the cold water tank 210 at a lower temperature. Specifically, an insulation layer can be provided in the cold water tank 210 to achieve this heat preservation effect. Optionally, a cooler can be provided in the ice water output channel 206 to further cool the water in the ice water output channel 206. In addition, when the water level in the cold water tank 210 is high, excess water is pumped from the cold water tank 210 into the raw water tank 110 through the first return channel 201.

[0043] Normal temperature water / hot water output process:

[0044] In one embodiment, when the second water inlet valve 1041 is opened, the pure water produced by the first filter component 120 can flow through the third water inlet channel to the external pure water container 310 for output. The third water inlet channel 104 can be provided with an instant heating module 330 and a water vapor separation box 340 located on the front side of the external pure water container 310. When the instant heating module 330 is started, the pure water is heated by the instant heating module 330 to form hot water, and the hot water then flows along the third water inlet channel 104 to the external pure water container 310 for output. At this time, the external pure water container 310 outputs hot water. When the instant heating module 330 is closed, the pure water flows directly along the third water inlet channel 104 to the external pure water container 310. At this time, the external pure water container 310 outputs pure water at room temperature.

[0045] In another embodiment, the water treatment system also includes a first water outlet channel 301 and a second water outlet channel 302 respectively connected to the third water inlet channel 104, the first water outlet channel 301 and the second water outlet channel 302 are independent of each other and do not interfere with each other, the first water outlet channel 301 is provided with the external pure water container 310, and the second water outlet channel 302 is provided with a fifth water pump 320, an instant heating module 330 and a water vapor separation box 340 along the water flow direction; the pure water in the third water inlet channel 104 is diverted through the first water outlet channel 301 and the second water outlet channel 302 respectively, wherein the pure water is diverted to the external pure water container 310 through the first water outlet channel 301 and outputs normal temperature pure water, and the pure water is diverted to the instant heating module 330 through the second water outlet channel 302 to be heated to form hot water and output.

[0046] It should be noted that the ice-making assembly 220 mentioned above can adopt the ice-making mechanism in the existing ice-making and water-dispensing machine, and the ice-crushing assembly 230 mentioned above can adopt the ice-crushing knife in the existing technology.
