Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, specifically to a sterilization and cleaning system and a kettle-type water purifier. Background Technology

[0002] A kettle-type water purifier, as the name suggests, is a water purifier product that temporarily stores purified water in a kettle. While kettle-type water purifiers make it convenient for consumers to access purified water, these products cannot avoid the growth of microorganisms or even excessive bacteria, especially when the kettle is not used for a long time and consumers do not clean it regularly. Furthermore, storing purified water in a kettle also presents the industry-wide problem of excessive TDS (Total Dissolved Solids) in the first kettle of water each day. Utility Model Content

[0003] The purpose of this invention is to provide a sterilization and cleaning system for improving water safety, and a kettle-type water purifier that uses the sterilization and cleaning system.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] In a first aspect, this utility model provides a sterilization and cleaning system, including a first inlet solenoid valve, a second inlet solenoid valve, a check valve, a filter device, a pure water jug, and a wastewater solenoid valve for connecting to a wastewater pipeline; the first inlet solenoid valve, the filter device, the check valve, and the pure water jug ​​are sequentially connected to form a water production pipeline for filtering tap water into pure water and storing it in the pure water jug; the pure water jug, the second inlet solenoid valve, the filter device, and the wastewater solenoid valve are sequentially connected to form a cleaning pipeline for reversing the flow of pure water from the pure water jug ​​into the filter device for rinsing and discharging it through the wastewater solenoid valve.

[0006] Furthermore, the sterilization and cleaning system also includes an ultraviolet lamp located between the check valve and the pure water kettle, which is used to sterilize the water filtered by the filtration device.

[0007] Furthermore, the sterilization and cleaning system also includes a three-way ball valve with a built-in filter. One end of the three-way ball valve is connected to a tap water pipe, and the other end is connected to a first inlet solenoid valve.

[0008] In one embodiment, both the first inlet solenoid valve and the second inlet solenoid valve are connected to a common pipe, which is connected to the filtration device.

[0010] Furthermore, the sterilization and cleaning system also includes a liquid level control component, which is used to monitor the water level of the purified water in the purified water pitcher.

[0011] In one embodiment, the liquid level control component includes a water level tank, a fixed sensing component, and a movable sensing component. The water level tank is connected to a pure water kettle. The fixed sensing component is fixed inside the water level tank and magnetically connected to the movable sensing component, and is used to send an electrical signal representing the water level to an external controller. The movable sensing component includes a float, a rocker arm, and a magnet. One end of the rocker arm is hinged to the fixed sensing component, and the other end is connected to the float.

[0021] It should be noted that the concepts of "first" and "second" mentioned in this utility model are only used to distinguish between devices, modules or units, and are not used to limit these devices, modules or units to necessarily be different devices, modules or units, nor are they used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0022] See Figure 1 This utility model provides a sterilization and cleaning system 100 and a kettle-type water purifier using the sterilization and cleaning system 100, which solves the problem of excessive TDS in the first kettle of water, while minimizing the growth of bacteria and ensuring the safety of the water used.

[0023] The sterilization and cleaning system 100 includes a water production pipeline and a cleaning pipeline. The water production pipeline is used to filter tap water into purified water, and the cleaning pipeline is used to backwash the internal components of the sterilization and cleaning system 100 that are prone to excessive TDS and bacterial growth using purified water.

[0024] Specifically, the sterilization and cleaning system 100 mainly consists of a first inlet solenoid valve 1, a second inlet solenoid valve 2, a check valve 3, a filter device, a pure water jug ​​5, and a wastewater solenoid valve 6. The first inlet solenoid valve 1, the filter device, the check valve 3, and the pure water jug ​​5 are sequentially connected to form a water production pipeline, used to filter tap water into pure water and store it in the pure water jug ​​5. The pure water jug ​​5, the second inlet solenoid valve 2, the filter device, and the wastewater solenoid valve 6 are sequentially connected to form a cleaning pipeline, used to reverse the flow of pure water from the pure water jug ​​5 into the filter device for rinsing and then discharge it through the wastewater solenoid valve 6.

[0025] The first inlet solenoid valve 1 is used to connect to tap water, and the wastewater solenoid valve 6 is used to connect to the wastewater pipeline to discharge the wastewater generated after rinsing the filter device. The filter device is a composite filter element 4, which includes a pleated PP, a pre-filter carbon fiber, a reverse osmosis membrane, and a post-filter carbon rod connected in sequence, thereby improving the filtration effect through multiple filtration processes.

[0026] The working principle of this utility model is as follows:

[0027] When water production is required, the sterilization and cleaning system 100 is put into water production mode. That is, according to the external control command, the first water inlet solenoid valve 1 and the check valve 3 are opened, the second water inlet solenoid valve 2 is closed, and tap water is supplied to the composite filter element 4. The tap water is filtered by the composite filter element 4 and then stored in the pure water pitcher 5. During the water production process, the wastewater solenoid valve 6 remains closed.

[0028] When the composite filter element 4 needs to be cleaned, the sterilization and cleaning system 100 is put into cleaning mode. That is, according to the external control command, the first inlet solenoid valve 1 is closed, the second inlet solenoid valve 2 and the wastewater solenoid valve 6 are opened, so that the pure water in the pure water jug ​​5 flows into the composite filter element 4, flushing down the unfiltered substances in front of the RO membrane of the composite filter element 4 and completely discharging them through the wastewater end.

[0029] Because the purified water is normally stored in the purified water pitcher 5, rather than in the composite filter cartridge 4, the water in the pitcher 5 will not be permeated by overnight water in the composite filter cartridge 4, resulting in a higher desalination rate for the purified water in the pitcher 5. Furthermore, antibacterial materials can be added to the inner wall of the pitcher 5, allowing it to store purified water for extended periods without bacterial growth. The system is configured to flush the purified water from the pitcher 5 back to the RO membrane of the composite filter cartridge 4, removing unfiltered substances before the membrane and discharging them completely through the wastewater outlet. This solves the problem of high TDS in the stagnant water of the integrated filter cartridge, which leads to high TDS in the first bottle of water.

[0030] Furthermore, the sterilization and cleaning system 100 also includes an ultraviolet lamp 7 disposed between the check valve 3 and the pure water kettle 5. The ultraviolet lamp 7 is used to sterilize the water filtered by the filtration device during water production, further improving the sterilization effect. It is understood that the pipes in the sterilization and cleaning system 100 are transparent flexible tubes, and the ultraviolet lamp 7 is disposed on the outside of the transparent flexible tube, allowing its light to penetrate into the transparent flexible tube to sterilize the water inside the tube.

[0031] Furthermore, the sterilization and cleaning system 100 also includes a three-way ball valve 8 with a built-in filter screen. One end of the three-way ball valve is connected to the tap water pipe, and the other end is connected to the first water inlet solenoid valve 1. The filter screen filters out larger impurities in the tap water, extending the service life of the composite filter element 4.

[0032] In one embodiment, the first inlet solenoid valve 1 and the second inlet solenoid valve 2 are both connected to a common pipe (not shown, the same below), which is connected to the composite filter element 4. This allows the opening and closing states of the first inlet solenoid valve 1 and the second inlet solenoid valve 2 to be controlled as needed. For example, during water production, the first inlet solenoid valve 1 can be opened and the second inlet solenoid valve 2 can be closed; during rinsing, the first inlet solenoid valve 1 can be closed and the second inlet solenoid valve 2 can be opened. This ensures the normal operation of water production and cleaning functions. Since the pipes are shared, pipes are saved, thereby reducing costs and also reducing the size of the sterilization and cleaning system 100.

[0033] In one embodiment, the common pipe is connected to the filter device (specifically the composite filter element 4) by a self-priming booster pump 9, thereby increasing the water pressure in the common pipe so that it can flow smoothly into the filter device (composite filter element 4).

[0034] Furthermore, the sterilization and cleaning system 100 also includes a liquid level control component 10, which is used to monitor and control the water level of the pure water in the pure water pitcher 5. When the water level in the pitcher is too low, the first water inlet solenoid valve 1 and the self-priming booster pump 9 of the water production pipeline are automatically opened to produce water. When the water level in the pitcher reaches the set value, the first water inlet solenoid valve 1 and the self-priming booster pump 9 are automatically closed to stop water production.

[0035] In one embodiment, the liquid level control component 10 includes a water level tank, a fixed sensing component, and a movable sensing component. The water level tank is located outside and communicates with the pure water kettle 5, ensuring that the water levels in the water level tank and the pure water kettle 5 are always balanced. The fixed sensing component is fixed inside the water level tank and magnetically connected to the movable sensing component, and is used to send an electrical signal representing the water level to an external controller. The movable sensing component includes a float, a rocker arm, and a magnet. One end of the rocker arm is hinged to the fixed sensing component, allowing the rocker arm to rotate relative to the fixed sensing component, and the other end is connected to the float. The magnet is slidably disposed inside the rocker arm.

[0036] In one embodiment, the fixed sensing component is a reed switch, which is horizontally fixed inside the water level tank. One end of the rocker arm is hinged to the reed switch. When the water level in the tank is lower than a set value, the float causes the rocker arm to rotate downward, causing the magnet to slide down and approach the float and move away from the reed switch. At this time, the reed switch outputs a signal indicating a low water level to an external controller, causing the external controller to control the first inlet solenoid valve 1 and the self-priming booster pump 9 to open and produce water. When the water level rises, the float rises, causing the rocker arm to rotate upward, and the magnet moves towards the reed switch. When the magnet reaches its limit position, the reed switch outputs a corresponding electrical signal to the external controller, and the external controller outputs a corresponding control signal to stop producing water.

[0037] By setting up an external water level tank connected to the pure water kettle 5, the water level tank and the pure water kettle 5 form a communicating vessel. By detecting the liquid level in the water level tank, the water level of the pure water inside the pure water kettle 5 can be known. There is no need to set up a water level detection probe inside the pure water kettle 5, which facilitates the design of the water level monitoring structure, ensures water safety, and improves the utilization rate of the internal space of the pure water kettle 5.

[0038] Secondly, the kettle-type water purifier of this utility model adopts the above-mentioned sterilization and cleaning system, which inevitably has the beneficial effects of the sterilization and cleaning system, and will not be elaborated here.
