[0071] The present disclosure is further illustrated below by way of embodiments, but the present disclosure is not limited to the scope of the embodiments described herein.

[0072] The prefixes such as "first" and "second" used in this disclosure are merely for distinguishing different descriptive objects and do not limit the position, order, priority, quantity, or content of the described objects. The use of ordinal numbers and other prefixes used to distinguish descriptive objects in this disclosure does not constitute a limitation on the described objects. The description of the described objects is given in the claims or the context of the embodiments, and should not be construed as an unnecessary limitation. Furthermore, in the description of this embodiment, unless otherwise stated, "multiple" means two or more.

[0073] See Figure 1If water purifier 19 and water heater 311 are used, their pipes are connected. After the circulation function of water heater 311 is turned on, the water in the inlet pipe 18 is heated. Water heater 311 needs to use cold water for return water to form a circulation loop. However, when the return water passes through water purifier 19, the water heated by water heater 311 may transfer heat to water purifier 19 through heat conduction. Furthermore, using water purifier 19 at this time will cause hot water to directly enter water purifier 19 through inlet pipe 18. The temperature in inlet pipe 18 is high, which easily breeds bacteria and produces scale and other impurities. If hot water directly enters water purifier 19 through inlet pipe 18, it will affect the water purification effect and service life of water purifier 19. If water purifier 19 uses a reverse osmosis membrane as a filter, it will also cause damage to the reverse osmosis membrane.

[0074] Based on this, embodiments of the present invention provide a water purification protection device, see [link to relevant documentation]. Figure 2 The water purification protection device 11 includes: a water storage device 12, a mixing pipe 13, a water outlet 14, a first valve 15, a second valve 16, a liquid level sensor (not shown in the figure), a first temperature sensor 17, and a controller (not shown in the figure).

[0075] The first valve 15 includes a first inlet and a first outlet. The first inlet is connected to the household inlet pipe 18, and the first outlet is connected to one end of the mixing pipe 13. The second valve 16 includes a second inlet, a third inlet, and a second outlet. The second inlet is connected to the other end of the mixing pipe 13, the third inlet is connected to the water storage device 12, and the second outlet is connected to the outlet 14 of the water purification protection device 11.

[0076] The outlet 14 of the water purification protection device 11 is used to connect to the inlet 20 of the water purifier 19. Therefore, the water in the inlet pipe 18 will be treated by the water purification protection device 11 before flowing into the inlet 20 of the water purifier 19, which can prevent the water in the inlet pipe 18 from flowing directly into the inlet 20 of the water purifier 19.

[0077] The liquid level sensor is electrically connected to the controller. The sensor is located within the water storage device 12 and is used to collect the water volume within the device and send the data to the controller. The location and number of liquid level sensors can be selected based on actual conditions and are not specifically limited here. If the water storage device 12 is large, multiple liquid level sensors can be used to accurately collect the water volume. The data collected by multiple sensors are sent to the controller, which calculates the average value to obtain a more accurate measurement. Multiple liquid level sensors can be distributed at different locations within the water storage device 12. The specific distribution and number of sensors can be set according to actual conditions and are not specifically limited here.

[0078] The first temperature sensor 17 is electrically connected to the controller. The first temperature sensor 17 collects the inlet water temperature in the inlet pipe 18 and sends the inlet water temperature to the controller. The first temperature sensor 17 can be set near the first water inlet end of the first valve 15 to collect the inlet water temperature in the inlet pipe 18, or it can be set in other places where the inlet water temperature can be collected. The specific setting can be set according to the actual situation, and no special limitation is made here.

[0079] The number and location of the first temperature sensor 17 can be set according to the actual situation, and there is no special limitation here. To improve the accuracy of the inlet water temperature acquisition, multiple temperature sensors can be set up, and the inlet water temperature collected by multiple temperature sensors can be sent to the controller. The controller calculates the average value of the inlet water temperature collected by multiple temperature sensors to obtain a more accurate inlet water temperature.

[0080] After receiving the water storage parameters collected by the first temperature sensor 17 and the liquid level sensor, the controller controls the opening degree of the first valve 15 and the second valve 16 according to the water storage parameters, so that the water temperature entering the water purifier 19 is within the target temperature range. The water storage parameters include: water storage volume and inlet water temperature.

[0081] The target temperature range can be selected based on actual conditions. Factors such as the correlation between bacterial growth and temperature, and the temperature resistance of the filter material in the water purifier 19 can be considered when choosing a suitable target temperature range. No specific limitations are imposed here. For example, higher temperatures make it easier for scale and bacteria to form in the water; therefore, a lower target temperature range needs to be set to avoid scale and bacteria formation. Assuming the filter material's temperature tolerance is 45℃, the target temperature range can be set below 45℃, for example, [0℃, 35℃].

[0082] The controller adjusts the opening of the first valve 15 and the second valve 16 according to the water storage parameters, allowing the water in the water storage device 12 to mix with the water flowing into the inlet pipe 18. This mixing and cooling function ensures that the water temperature entering the water purifier 19 is within the target temperature range, thus preventing water from the inlet pipe 18 from flowing directly into the water purifier 19. The water temperature in the storage device is generally low, such as room temperature water.

[0083] The water purification protection device 11 can be flexibly installed on the inlet pipe 18 between the existing water purifier 19 and water heater 311 in the home. It plays a role in protecting the water purifier 19, so that the water temperature entering the water purifier 19 is within the target temperature range, avoiding the growth of bacteria and the formation of scale due to high water temperature, and improving the water purification effect and service life of the water purifier 19.

[0084] In this embodiment, the water purification protection device 11 can be installed according to user needs. It can be flexibly installed on the outside of the existing water purifier 19 to protect the water purifier 19. For users who have already purchased the water purifier 19, it can avoid replacing the existing water purifier 19, reducing replacement costs. The water purification protection device 11 is flexible and easy to install. It controls the opening of the first valve 15 and the second valve 16 based on the water storage parameters to ensure that the water temperature entering the water purifier 19 is within the target temperature range. This prevents hot water from flowing into the water inlet 20 of the water purifier 19 through the inlet pipe 18, and prevents the water from breeding bacteria and producing scale due to high temperature, thereby improving the water purification effect and service life of the water purifier 19.

[0085] In one embodiment, in response to the water storage parameters meeting a first preset condition, the controller adjusts the opening of the first valve 15.

[0086] The first preset conditions include: the inlet water temperature is greater than the temperature threshold and the water storage volume is less than the lower limit threshold. If the inlet water temperature is greater than the temperature threshold, it means that the water temperature in the inlet pipe 18 exceeds the target temperature range. If it directly enters the water purifier 19, it will have adverse effects on the water purifier 19, such as affecting its service life and purification effect. Therefore, mixing and cooling are necessary. However, if the water storage volume is less than the lower limit threshold, it means that the water in the storage device 12 is insufficient to achieve mixing and cooling. To protect the water purifier 19, the opening of the first valve 15 needs to be adjusted to reduce the amount of water flowing into the water purifier 19 from the inlet pipe 18, preventing excessively hot water from entering the water purifier 19 and thus protecting the water purifier 19.

[0087] Adjusting the opening of the first valve 15 includes reducing the opening of the first valve 15 to the target opening. The temperature threshold, the lower limit threshold of water flow, and the target opening can be set according to the actual situation and are not specifically limited here.

[0088] Specifically, when the water level sensor detects that the water volume is less than the lower limit threshold, the first temperature sensor 17 detects that the inlet water temperature is greater than the temperature threshold. The controller will reduce the opening of the first valve 15 to the target opening, thereby reducing the amount of water flowing in through the first valve 15 and protecting the water purifier 19.

[0089] In this embodiment, when the inlet water temperature is greater than the temperature threshold and the water storage volume is less than the lower limit threshold, the controller will reduce the opening of the first valve 15 to the target opening to ensure that the water temperature entering the water purifier 19 is within the target temperature range, thus preventing the water from breeding bacteria and producing scale due to high temperature.

[0090] In one embodiment, adjusting the opening of the first valve 15 further includes adjusting the opening of the first valve 15 to zero, that is, closing the first valve 15.

[0091] Specifically, when the water level sensor detects that the water volume is less than the lower limit threshold and the first temperature sensor 17 detects that the inlet water temperature is greater than the temperature threshold, the controller adjusts the opening of the first valve 15 to zero, that is, closes the first valve 15 to prevent hot water from flowing into the water purifier 19 through the first valve 15.

[0092] In this embodiment, when the inlet water temperature is greater than the temperature threshold and the water storage volume is less than the lower limit threshold, the controller will close the first valve 15 to prevent hot water from flowing into the water purifier 19 through the first valve 15, thereby improving the water purification effect and service life of the water purifier 19.

[0093] In one embodiment, the water storage parameter further includes the storage duration of the water in the water storage device 12.

[0094] In response to the water storage parameters meeting the second preset condition, the controller adjusts the opening of the second valve 16 to connect the water storage device 12, the mixing pipeline 13 and the outlet 14 of the water purification protection device 11.

[0095] The second preset condition includes at least one of the following: the water storage volume is greater than or equal to the upper limit threshold, the storage time is greater than the preset time, and the inlet water temperature is greater than the temperature threshold. The upper limit threshold, the preset time, and the temperature threshold can be set according to the actual situation and are not specifically limited here.

[0096] If the inlet water temperature exceeds the temperature threshold, it indicates that the water temperature in the inlet pipe 18 exceeds the target temperature range. Directly introducing the water into the water purifier 19 would adversely affect it, necessitating water mixing and cooling. If the stored water volume is greater than or equal to the upper limit threshold, it indicates that the current water volume is sufficient for water mixing. If the storage time exceeds the preset time, it indicates that the water in the storage device 12 has not been used for a long time. To prevent scale and bacteria buildup from prolonged inactivity, the opening of the second valve 16 needs to be controlled to allow the water in the storage device 12 to be used for water mixing.

[0097] Assuming the temperature threshold is 35℃, the first temperature sensor 17 detects that the inlet water temperature is greater than 35℃, and the water storage volume collected by the liquid level sensor is greater than or equal to the upper limit threshold of water volume. Therefore, water mixing and cooling are required. The controller controls the opening of the second valve 16 to connect the water storage device 12, the water mixing pipeline 13 and the outlet 14 of the water purification protection device 11, so that the water temperature entering the water purifier 19 is within the target temperature range.

[0098] It should be noted that if the water storage volume is less than the lower limit threshold, it means that the current water storage volume is insufficient to achieve water mixing, and water mixing will not be carried out, that is, the water storage device 12, the water mixing pipeline 13 and the water purification protection device 11 will not be connected.

[0099] In response to a user's water request, the water in the water storage device 12 is used first. The controller controls the opening of the second valve 16 to connect the water storage device 12, the mixing pipe 13 and the outlet 14 of the water purification protection device 11, so that the water in the water storage device 12 flows out through the outlet 14 to complete the replacement of the water in the water storage device 12.

[0100] Specifically, the controller adjusts the opening of the second and third inlet terminals of the second valve 16 based on the mixing ratio of the water storage device 12 and the mixing pipe 13. The mixing ratio of the water storage device 12 and the mixing pipe 13 can be set according to actual conditions and is not specifically limited here. For different water purifiers 19, the controller can set the mixing ratio based on the water storage capacity per unit time of the water purifier 19 and the volume of the water storage device 12, rather than using the same mixing ratio for different water purifiers 19. For the same water purifier 19, the controller can determine the mixing ratio based on the water storage parameters, preventing the water in the water storage device 12 from being depleted, and instead achieving water circulation and mixing for cooling.

[0101] Specifically, when the water level sensor collects the water storage volume and the first temperature sensor 17 detects that the inlet water temperature meets the second preset condition, the controller adjusts the opening of the second valve 16 to connect the water storage device 12, the mixing pipe 13 and the outlet 14 of the water purification protection device 11, so as to achieve the purpose of mixing water and cooling.

[0102] The second valve 16 can be implemented in ways including but not limited to an electric three-way valve. The specific implementation can be set according to the actual situation and is not specifically limited here.

[0103] In this embodiment, the water storage parameters meet the second preset conditions. The controller is used to adjust the opening of the second valve 16 so that the water storage device 12, the mixing pipe 13 and the outlet 14 of the water purification protection device 11 are connected so that the water temperature entering the water purifier 19 is within the target temperature range, so as to avoid the growth of bacteria and the generation of scale due to high water temperature, thereby improving the water purification effect and service life of the water purifier 19.

[0104] In one embodiment, in response to the water storage parameters meeting a third preset condition, the controller adjusts the opening of the second valve 16 to connect the water storage device 12, the mixing pipeline 13, and the outlet 14 of the water purification protection device 11.

[0105] The third preset conditions include: the inlet water temperature is greater than the temperature threshold, the water storage volume is greater than or equal to the lower limit threshold, and the water storage volume is less than the upper limit threshold.

[0106] In this embodiment, the water storage parameters meet the third preset condition. The controller is used to adjust the opening of the second valve 16 so that the water storage device 12, the mixing pipe 13 and the outlet 14 of the water purification protection device 11 are connected so that the water temperature entering the water purifier 19 is within the target temperature range, so as to avoid the growth of bacteria and the generation of scale due to high water temperature, thereby improving the water purification effect and service life of the water purifier 19.

[0107] In one embodiment, the water storage parameter further includes: the water level in the water storage device 12. The first preset condition further includes: the water level is less than the lower limit threshold. The second preset condition further includes: the water level is greater than or equal to the upper limit threshold.

[0108] The upper and lower limits of the liquid level can be set according to the actual situation, and no special restrictions are imposed here.

[0109] When the water storage parameters meet the first preset conditions, that is, when the water level collected by the level sensor is less than the lower limit threshold and the inlet water temperature detected by the first temperature sensor 17 is greater than the temperature threshold, the controller will adjust the opening of the first valve 15 to reduce the amount of water flowing in through the first valve 15, thereby protecting the water purifier 19.

[0110] When the water storage parameters meet the second preset conditions, that is, when the water storage volume is greater than or equal to the upper limit threshold of water volume, the storage time is greater than the preset time and the inlet water temperature is greater than the temperature threshold, the controller adjusts the opening of the second valve 16 so that the water storage device 12, the mixing pipe 13 and the outlet 14 of the water purification protection device 11 are connected to achieve the purpose of mixing water and cooling.

[0111] Specifically, if the stored water volume is greater than or equal to the upper limit threshold, satisfying the second preset condition, the controller adjusts the opening of the second valve 16 to achieve water mixing and cooling. If the stored water volume is greater than or equal to the upper limit threshold and the storage time is greater than a preset time, satisfying the second preset condition, the controller adjusts the opening of the second valve 16 to achieve water mixing and cooling. If all three conditions are met simultaneously: stored water volume greater than or equal to the upper limit threshold, storage time greater than a preset time, and inlet water temperature greater than a temperature threshold, the controller adjusts the opening of the second valve 16 to achieve water mixing and cooling.

[0112] In this embodiment, the water storage parameters also include the water storage level. The controller receives the water storage level collected by the level sensor and adjusts the opening of the second valve 16 so that the water temperature entering the water purifier 19 is within the target temperature range, thereby preventing the water from breeding bacteria and producing scale due to high temperature, and improving the water purification effect and service life of the water purifier 19.

[0113] In one embodiment, the water storage parameter further includes the water temperature within the water storage device 12. A second temperature sensor is provided within the water storage device 12, and the second temperature sensor is electrically connected to the controller. The second temperature sensor is used to collect the water temperature and send the water temperature to the controller.

[0114] To improve the accuracy of water storage temperature acquisition, multiple temperature sensors can be installed to measure the water storage temperature. These sensors can be distributed at different locations within the water storage device 12. The sensors transmit the collected water storage temperatures to the controller, which then averages the values ​​to obtain a more accurate water storage temperature. The location and number of the second temperature sensor can be set according to actual conditions and are not specifically limited here.

[0115] The controller receives the water temperature collected by the second temperature sensor and adjusts the opening degree of the second and third water inlets of the second valve 16. The opening degree of the second water inlet is negatively correlated with the water temperature, while the opening degree of the third water inlet is positively correlated with the water temperature.

[0116] Specifically, the opening degrees of the second and third water inlets are determined based on the inlet water temperature detected by the first temperature sensor 17 and the storage water temperature detected by the second temperature sensor, thereby distributing the water flow to the second and third water inlets to ensure that the water temperature entering the water purifier 19 is within the target temperature range. If the inlet water temperature is higher, the opening degree of the second water inlet is smaller; conversely, if the inlet water temperature is lower, the opening degree of the second water inlet is larger. Similarly, if the storage water temperature is higher, the opening degree of the third water inlet is larger; conversely, if the storage water temperature is lower, the opening degree of the third water inlet is smaller.

[0117] In this embodiment, a second temperature sensor is provided in the water storage device 12. The controller receives the water temperature collected by the second temperature sensor and adjusts the opening of the second inlet and the third inlet of the second valve 16 according to the water temperature and the inlet water temperature. The water in the mixing pipe 13 and the water in the water storage device 12 can be mixed so that the water temperature entering the water purifier 19 is within the target temperature range, avoiding the growth of bacteria and the formation of scale due to high temperature, and improving the water purification effect and service life of the water purifier 19.

[0118] In one embodiment, the water purification protection device 11 further includes a third valve 22. The fourth inlet of the third valve 22 is connected to the municipal water inlet pipe, and the third outlet of the third valve 22 is connected to the water inlet of the water storage device 12.

[0119] The controller also controls the third valve 22 to open when the water storage volume is less than the upper limit threshold.

[0120] In this embodiment, the fourth water inlet is connected to the municipal water inlet pipe, and the third water outlet is connected to the water inlet of the water storage device 12. When the water storage volume is less than the upper limit threshold, water is injected into the water storage device 12 through the municipal water inlet pipe to avoid insufficient water storage when mixing is required. The device is highly intelligent.

[0121] In one embodiment, the fourth inlet of the third valve 22 is connected to the purified water outlet 21 of the water purifier 19, and the third outlet of the third valve 22 is connected to the water inlet of the water storage device 12.

[0122] The controller also controls the third valve 22 to open when the water storage volume is greater than the lower water volume threshold and less than the upper water volume threshold.

[0123] When the water purification protection device 11 is used for the first time, the controller controls the third valve 22 to open, and the water prepared by the water purifier 19, V1L, is stored in the water storage device 12 of the water purification protection device 11. Here, V1 represents the volume of water when the stored water is equal to the lower limit threshold of the water volume.

[0124] When the user is not using the water purifier 19, if the water storage volume is less than the upper limit threshold, the controller will control the third valve 22 to open so that the water prepared by the water purifier 19 flows into the water inlet of the water storage device 12 through the water purification outlet 21. When the water storage volume is equal to the upper limit threshold, the controller will control the third valve 22 to close and stop water from being injected into the water storage device 12.

[0125] It should be noted that after the water purifier 19 filters the water using a filter, the water flows out through the purified water outlet 21 to ensure that the water flowing into the water storage device 12 meets the water quality requirements.

[0126] In this embodiment, when the water storage volume is greater than the lower threshold and less than the upper threshold, the third valve 22 is opened to inject water into the water storage device 12, thus avoiding insufficient water storage when mixing is required. This method is highly intelligent and, compared to injecting water through the municipal water inlet pipe, results in better water quality entering the water storage device, reducing the generation of scale and other impurities, protecting the water purifier 19, and extending the service life of the water purifier 19.

[0127] In one embodiment, the controller also adjusts the opening of the third valve 22 to zero in response to the water storage volume being equal to the upper limit threshold of the water volume.

[0128] When the water storage capacity is equal to the upper limit threshold of the water volume, the water storage capacity can meet the needs of mixing water, and there is no need to inject water into the water storage device 12. Therefore, it is necessary to control the third valve 22 to close and stop injecting water into the water storage device 12.

[0129] In this embodiment, when the water storage volume is equal to the upper limit threshold of the water volume, the opening of the third valve 22 is adjusted, and the water supply to the water storage device 12 is automatically stopped when the water is full, so as to realize intelligent management and avoid water waste.

[0130] In one embodiment, the water purification protection device 11 further includes a filter device 23. The filter device 23 is disposed in the mixing pipe, and the water flowing out from the first end of the mixing pipe 13 is filtered by the filter device 23 and then flows out from the second end of the mixing pipe 13.

[0131] Considering that the water is more prone to bacteria and scale growth when the temperature inside the inlet pipe 18 is too high, and the resulting impurities will enter the water purifier 19, which will have an adverse effect on the water purifier 19, such as affecting the service life and water purification effect of the water purifier 19, a filtration module is set up so that the water flowing out from the first end of the mixing pipe 13 can be filtered by the filtration device 23 and then flow out from the second end of the mixing pipe 13.

[0132] The filter device 23 is mainly used to filter out scale and bacteria. The filter element of the filter device 23 can be set according to the actual situation, and no special limitation is made here.

[0133] In this embodiment, the water in the mixing pipe 13 is filtered by the filtration device 23, which improves the water quality of the water entering the water purifier 19, reduces the wear on the filter of the water purifier 19, and extends the service life of the water purifier 19.

[0134] In one embodiment, the water purification protection device 11 further includes a sterilization device. The sterilization device is disposed within the water storage device 12 and is electrically connected to the controller.

[0135] The controller also responds to the fact that the water in the water storage device 12 has been stored for a longer period than a preset time, and starts the sterilization device of the water storage device 12, and stops the sterilization device after the sterilization time is reached.

[0136] If the water in the water storage device 12 is stored for a longer than preset time, the water quality will deteriorate. To prevent this, the controller activates the water storage device 12 to sterilize the water after the preset storage time has elapsed. Once the sterilization time has been reached, sterilization is complete, the water quality in the water storage device 12 meets the requirements, and the sterilization device is shut off, thus reducing unnecessary energy consumption.

[0137] The preset time and sterilization duration can be set according to the actual situation, and no special limit is set here.

[0138] In this embodiment, after the storage time exceeds the preset time, the water in the water storage device 12 is sterilized to remove or reduce microbial pollution in the water and improve water quality. After the sterilization time is reached, the sterilization device is turned off. When the water quality meets the requirements, turning off the sterilization device can meet actual needs, avoid resource waste, and save energy.

[0139] In one embodiment, the water purification protection device 11 further includes an alarm.

[0140] The liquid level sensor and the first temperature sensor 17 are electrically connected to the alarm. The alarm will issue a prompt to suspend use when the water level is less than the lower limit threshold and the inlet water temperature is greater than the temperature threshold.

[0141] When the inlet water temperature collected by the first temperature sensor 17 is greater than the temperature threshold, the water in the water storage device 12 needs to be mixed to cool it down. However, the water storage volume collected by the liquid level sensor at this time is less than the lower limit threshold of water volume. The water storage volume is insufficient and therefore the mixing effect cannot be guaranteed. In order to ensure that hot water with a temperature greater than the temperature threshold does not flow into the water purifier 19, the alarm issues a prompt to stop using the water purifier 19 to remind the user to stop using the water purifier 19.

[0142] When the inlet water temperature is below the temperature threshold or the water storage volume is above the lower water volume threshold, the alarm will sound a prompt to resume use. If the inlet water temperature is below the temperature threshold, it means that mixing is not required, and the water temperature entering the water purifier 19 is within the target temperature range. If the water storage volume is above the lower water volume threshold, it means that the storage volume is sufficient to achieve mixing, ensuring that the water temperature entering the water purifier 19 is within the target temperature range. Since hot water above the temperature threshold will not flow into the water purifier 19, the alarm will sound a prompt to resume use, reminding the user that the water purifier 19 can be used.

[0143] In this embodiment, when the inlet water temperature is greater than the temperature threshold and the water storage volume is less than the lower limit threshold, the alarm will issue a prompt to suspend use, so as to prevent hot water from flowing into the water purifier 19 due to user use, and to prevent bacteria and scale from growing in the water due to high temperature, thereby improving the service life of the water purifier 19.

[0144] In one embodiment, the water storage device 12 has a turbulent flow structure 24.

[0145] The turbulence structure 24 is used to lengthen the path of water flowing into and out of the water storage device 12. With the turbulence structure 24, the water flow in the water storage device 12 can be abstractly regarded as flowing in an S-shape, disturbing the water flow inside the water storage device 12. Without the turbulence structure 24, water would flow directly out after entering the water storage device 12, and some water would remain in the water storage device 12 for a long time, thus affecting the water quality.

[0146] The location and number of turbulence structures 24 can be set according to actual conditions and are not specifically limited here. Turbulence structures 24 include, but are not limited to, baffles. Perforations may be made on the baffles to appropriately reduce water flow resistance. The number and location of the perforations can be set according to actual conditions and are not specifically limited here.

[0147] In this embodiment, the water storage device 12 has a turbulent flow structure 24, which can disturb the water flow inside the water storage device 12 and prevent some water from remaining in the water storage device 12 for a long time, thus avoiding affecting the water quality.

[0148] In one embodiment, the water storage device 12 is equipped with a water pump.

[0149] When the inlet water temperature exceeds the temperature threshold and water mixing for cooling is required, a water pump is used to direct the water in the storage device 12 to the third inlet, thus achieving water mixing. The number, location, and type of water pumps can be set according to actual conditions and are not specifically limited here.

[0150] In this embodiment, the water storage device 12 is equipped with a water pump, which can overcome gravity and lift the water in the water storage device 12 to a higher position than the water storage device 12, and deliver it to the third water inlet of the second valve, thereby enhancing the reliability and flexibility of water mixing.

[0151] Figure 3 A flowchart illustrating a control method for a water purification protection device 11 provided as an exemplary embodiment of this disclosure.

[0152] The water purification protection device 11 includes: a water storage device 12, a mixing pipe 13, a water outlet 14, a first valve 15, a second valve 16, a liquid level sensor, a first temperature sensor 17, and a controller. The first valve 15 includes: a first water inlet and a first water outlet, and the second valve 16 includes: a second water inlet, a third water inlet, and a second water outlet.

[0153] The first water inlet is used to connect to the household inlet pipe 18, the first water outlet is connected to one end of the mixing pipe 13, the second water inlet is connected to the other end of the mixing pipe 13, the third water inlet is connected to the water storage device 12, and the second water outlet is connected to the outlet 14 of the water purification protection device 11.

[0154] The outlet 14 of the water purification protection device 11 is used to connect to the inlet 20 of the water purifier 19. Therefore, the water in the inlet pipe 18 will be treated by the water purification protection device 11 before flowing into the inlet 20 of the water purifier 19, which can prevent the water in the inlet pipe 18 from flowing directly into the inlet 20 of the water purifier 19.

[0155] Both the first temperature sensor 17 and the liquid level sensor are electrically connected to the controller. The liquid level sensor is installed inside the water storage device 12. The first temperature sensor 17 collects the inlet water temperature in the inlet pipe 18 and sends the inlet water temperature to the controller. The liquid level sensor collects the water storage volume in the water storage device 12 and sends the water storage volume to the controller.

[0156] The liquid level sensor is electrically connected to the controller. The sensor is located within the water storage device 12 and is used to collect the water volume within the device and send the data to the controller. The location and number of liquid level sensors can be selected based on actual conditions and are not specifically limited here. If the water storage device 12 is large, multiple liquid level sensors can be used to accurately collect the water volume. The data collected by multiple sensors are sent to the controller, which calculates the average value to obtain a more accurate measurement. Multiple liquid level sensors can be distributed at different locations within the water storage device 12. The specific distribution and number of sensors can be set according to actual conditions and are not specifically limited here.

[0157] The first temperature sensor 17 is electrically connected to the controller. The first temperature sensor 17 collects the inlet water temperature in the inlet pipe 18 and sends the inlet water temperature to the controller. The first temperature sensor 17 can be set near the first water inlet end of the first valve 15 to collect the inlet water temperature in the inlet pipe 18, or it can be set in other places where the inlet water temperature can be collected. The specific setting can be set according to the actual situation, and no special limitation is made here.

[0158] The number and location of the first temperature sensor 17 can be set according to the actual situation, and there is no special limitation here. To improve the accuracy of the inlet water temperature acquisition, multiple temperature sensors can be set up, and the inlet water temperature collected by multiple temperature sensors can be sent to the controller. The controller calculates the average value of the inlet water temperature collected by multiple temperature sensors to obtain a more accurate inlet water temperature.

[0159] The control method for the water purification protection device 11 includes:

[0160] Step S101: Obtain water storage parameters.

[0161] The water storage parameters include: the water storage capacity in the water storage device 12 and the inlet water temperature in the inlet pipe 18.

[0162] Step S102: Control the opening degree of the first valve 15 and / or the opening degree of the second valve 16 according to the water storage parameters so that the water temperature entering the water purifier 19 is within the target temperature range.

[0163] The target temperature range can be selected based on actual conditions. Factors such as the correlation between bacterial growth and temperature, and the temperature resistance of the filter material in the water purifier 19 can be considered when choosing a suitable target temperature range; no specific limitations are imposed here. For example, higher temperatures make it easier for scale and bacteria to form in the water, so a lower target temperature range needs to be set to avoid scale and bacteria formation. Assuming the filter material's temperature tolerance is 45℃, the target temperature range can be set below 45℃, such as 35℃.

[0164] The opening of the first valve 15 and the second valve 16 is controlled according to the water storage parameters so that the water in the water storage device 12 can be mixed with the water flowing into the household pipe 18 to achieve the function of mixing water and cooling, so that the water temperature entering the water purifier 19 can be within the target temperature range, thereby preventing the water in the household pipe 18 from flowing directly into the water purifier 19.

[0165] In this embodiment, the opening degree of the first valve 15 and the second valve 16 are controlled based on the water storage parameters so that the water temperature entering the water purifier 19 is within the target temperature range, preventing hot water from flowing into the water inlet 20 of the water purifier 19 through the inlet pipe 18, preventing bacteria and scale from growing in the water due to high temperature, and improving the water purification effect and service life of the water purifier 19.

[0166] In one embodiment, the water storage parameter further includes the storage duration of the water in the water storage device 12.

[0167] Step S102 includes: adjusting the opening of the first valve 15 in response to the water storage parameters meeting a first preset condition; adjusting the opening of the second valve 16 in response to the water storage parameters meeting a second preset condition and / or the water storage parameters meeting a third preset condition, so as to connect the outlet 14 of the water storage device 12, the mixing pipeline 13 and the water purification protection device 11.

[0168] Adjusting the opening of the first valve 15 includes reducing the opening of the first valve 15 to the target opening.

[0169] The first preset condition includes: the inlet water temperature is greater than the temperature threshold and the stored water volume is less than the lower limit threshold. The second preset condition includes at least one of the following: the stored water volume is greater than or equal to the upper limit threshold, the storage time is greater than the preset time and the inlet water temperature is greater than the temperature threshold; the third preset condition includes: the inlet water temperature is greater than the temperature threshold, the stored water volume is greater than or equal to the lower limit threshold, and the stored water volume is less than the upper limit threshold.

[0170] Temperature threshold, lower water volume threshold, upper water volume threshold, preset time, and target opening degree can be set according to actual conditions, and no special restrictions are imposed here.

[0171] When the water storage parameters meet the first preset condition, that is, when the water storage volume collected by the liquid level sensor is less than the lower limit threshold of water volume, the first temperature sensor 17 detects that the inlet water temperature is greater than the temperature threshold, and reduces the opening of the first valve 15 to the target opening, thereby reducing the amount of water flowing in through the first valve 15 and playing the role of protecting the water purifier 19.

[0172] If the inlet water temperature is greater than the temperature threshold, it indicates that water mixing and cooling are required. If the water storage volume is greater than or equal to the upper limit threshold, it indicates that the current water volume is sufficient for water mixing. If the storage time is greater than the preset time, it indicates that the water in the water storage device 12 has not been used for a long time, and the opening of the second valve 16 needs to be controlled to mix the water and allow the water in the water storage device 12 to flow.

[0173] When the water storage parameters meet the second preset conditions, assuming the temperature threshold is 35℃, the first temperature sensor 17 detects that the inlet water temperature is greater than 35℃, and the water storage volume collected by the liquid level sensor is greater than or equal to the upper limit threshold of water volume. Therefore, water mixing and cooling are required. The controller controls the opening of the second valve 16 to connect the water storage device 12, the water mixing pipeline 13 and the outlet 14 of the water purification protection device 11, so that the water temperature entering the water purifier 19 is within the target temperature range.

[0174] When the water storage parameters meet the third preset condition, the water storage volume is greater than or equal to the lower limit threshold and less than the upper limit threshold, that is, the water storage volume is between the lower limit threshold and the upper limit threshold. If the inlet water temperature is greater than the temperature threshold, water mixing and cooling are required. The controller controls the opening of the second valve 16 to connect the water storage device 12, the mixing pipeline 13 and the outlet 14 of the water purification protection device 11, so that the water temperature entering the water purifier 19 is within the target temperature range.

[0175] It should be noted that if the water storage volume is less than the lower limit threshold, it means that the current water storage volume is insufficient to achieve water mixing, and water mixing will not be carried out, that is, the water storage device 12, the water mixing pipeline 13 and the water purification protection device 11 will not be connected.

[0176] In response to a user's water request, the water in the water storage device 12 is used first. The controller controls the opening of the second valve 16 to connect the water storage device 12, the mixing pipe 13 and the outlet 14 of the water purification protection device 11, so that the water in the water storage device 12 flows out through the outlet 14 to complete the replacement of the water in the water storage device 12.

[0177] Specifically, the opening degrees of the second and third inlet terminals of the second valve 16 are adjusted according to the mixing ratio of the water storage device 12 and the mixing pipe 13. The mixing ratio of the water storage device 12 and the mixing pipe 13 can be set according to actual conditions and is not specifically limited here. For different water purifiers 19, the mixing ratio can be set according to the water storage capacity per unit time of the water purifier 19 and the volume of the water storage device 12, rather than using the same mixing ratio for different water purifiers 19. For the same water purifier 19, the mixing ratio can be determined according to the water storage parameters, so as not to deplete the water in the water storage device 12, but to achieve water circulation and mixing and cooling.

[0178] Specifically, when the water storage volume collected by the liquid level sensor and the inlet water temperature detected by the first temperature sensor 17 meet the second preset condition, the opening of the second valve 16 is adjusted so that the outlet 14 of the water storage device 12, the mixing pipe 13 and the water purification protection device 11 are connected to achieve the purpose of mixing water and cooling.

[0179] The second valve 16 can be implemented in ways including but not limited to an electric three-way valve. The specific implementation can be set according to the actual situation and is not specifically limited here.

[0180] In this embodiment, when the water storage parameters meet the first preset condition, the opening of the first valve 15 is reduced to the target opening. When the water storage parameters meet the second preset condition, the opening of the second valve 16 is adjusted so that the water storage device 12, the mixing pipe 13 and the outlet 14 of the water purification protection device 11 are connected, so that the water temperature entering the water purifier 19 is within the target temperature range, avoiding the growth of bacteria and the formation of scale due to high water temperature, and improving the water purification effect and service life of the water purifier 19.

[0181] In one embodiment, adjusting the opening of the first valve 15 further includes adjusting the opening of the first valve 15 to zero, that is, closing the first valve 15.

[0182] Specifically, when the water level sensor detects that the water volume is less than the lower limit threshold and the first temperature sensor 17 detects that the inlet water temperature is greater than the temperature threshold, the opening of the first valve 15 is adjusted to zero, that is, the first valve 15 is closed to prevent hot water from flowing into the water purifier 19 through the first valve 15.

[0183] In this embodiment, when the inlet water temperature is greater than the temperature threshold and the water storage volume is less than the lower limit threshold, the first valve 15 is closed to prevent hot water from flowing into the water purifier 19 through the first valve 15, thereby improving the water purification effect and service life of the water purifier 19.

[0184] In one embodiment, the water storage parameter further includes: the water level in the water storage device 12. The first preset condition further includes: the water level is less than a lower water level threshold. The second preset condition further includes: the water level is greater than or equal to an upper water level threshold. The third preset condition further includes: the water level is greater than or equal to a lower water level threshold and less than an upper water level threshold.

[0185] The upper and lower limits of the liquid level can be set according to the actual situation, and no special restrictions are imposed here.

[0186] When the water storage parameters meet the first preset conditions, that is, when the water level collected by the level sensor is less than the lower limit threshold and the inlet water temperature detected by the first temperature sensor 17 is greater than the temperature threshold, the opening of the first valve 15 is adjusted to reduce the amount of water flowing in through the first valve 15, thereby protecting the water purifier 19.

[0187] When the water storage parameters meet the second preset conditions, that is, when the water storage volume is greater than or equal to the upper limit threshold of water volume, the storage time is greater than the preset time and the inlet water temperature is greater than the temperature threshold, the opening of the second valve 16 is adjusted so that the water storage device 12, the mixing pipe 13 and the outlet 14 of the water purification protection device 11 are connected to achieve the purpose of mixing water and cooling.

[0188] When the water storage parameters meet the third preset condition, that is, when the water storage level collected by the level sensor is greater than or equal to the lower limit threshold and less than the upper limit threshold, and the first temperature sensor 17 detects that the inlet water temperature is greater than the temperature threshold, the opening of the second valve 16 is adjusted so that the water storage device 12, the mixing pipe 13 and the outlet 14 of the water purification protection device 11 are connected to achieve the purpose of mixing water and cooling.

[0189] In this embodiment, the water storage parameters also include the water storage level. Based on the water storage level collected by the level sensor, the opening of the second valve 16 is adjusted so that the water temperature entering the water purifier 19 is within the target temperature range, thereby preventing the water from breeding bacteria and producing scale due to high temperature, and improving the water purification effect and service life of the water purifier 19.

[0190] In one embodiment, the water storage parameter further includes the water temperature within the water storage device 12. A second temperature sensor is provided within the water storage device 12; the second temperature sensor is electrically connected to the controller, and is used to collect the water temperature and send it to the controller.

[0191] To improve the accuracy of water storage temperature acquisition, multiple temperature sensors can be installed to measure the water storage temperature. These sensors can be distributed at different locations within the water storage device 12. The sensors transmit the collected water storage temperatures to the controller, which then averages the values ​​to obtain a more accurate water storage temperature. The location and number of the second temperature sensor can be set according to actual conditions and are not specifically limited here.

[0192] Step S102 further includes: adjusting the opening degree of the second inlet and the third inlet of the second valve 16 according to the water storage temperature.

[0193] Among them, the opening degree of the second water inlet is negatively correlated with the water inlet temperature, while the opening degree of the third water inlet is positively correlated with the water storage temperature.

[0194] Specifically, the opening degrees of the second and third water inlets are determined based on the inlet water temperature detected by the first temperature sensor 17 and the storage water temperature detected by the second temperature sensor, thereby distributing the water flow to the second and third water inlets to ensure that the water temperature entering the water purifier 19 is within the target temperature range. If the inlet water temperature is higher, the opening degree of the second water inlet is smaller; conversely, if the inlet water temperature is lower, the opening degree of the second water inlet is larger. Similarly, if the storage water temperature is higher, the opening degree of the third water inlet is larger; conversely, if the storage water temperature is lower, the opening degree of the third water inlet is smaller.

[0195] In this embodiment, a second temperature sensor is provided in the water storage device 12. The opening of the second inlet and the third inlet of the second valve 16 is adjusted according to the water storage temperature and the inlet water temperature. The water in the mixing pipe 13 and the water in the water storage device 12 can be mixed so that the water temperature entering the water purifier 19 is within the target temperature range. This avoids the growth of bacteria and the formation of scale due to high water temperature, thereby improving the water purification effect and service life of the water purifier 19.

[0196] In one embodiment, the water purification protection device 11 further includes a third valve 22. The fourth inlet of the third valve 22 is connected to the purified water outlet 21 of the water purifier 19, and the third outlet of the third valve 22 is connected to the water inlet of the water storage device 12.

[0197] The control method of the water purification protection device 11 also includes: in response to the water storage volume being less than the upper limit threshold of water volume, controlling the third valve 22 to open.

[0198] When the water purification protection device 11 is used for the first time, the third valve 22 is opened, and V1L of water prepared by the water purifier 19 is stored in the water storage device 12 of the water purification protection device 11. Here, V1 represents the volume of water when the stored water is equal to the lower limit threshold of the water volume.

[0199] When the user is not using the water purifier 19, if the water storage volume is less than the upper limit threshold, the third valve 22 is opened so that the water prepared by the water purifier 19 flows into the water inlet of the water storage device 12 through the water purification outlet 21. When the water storage volume is equal to the upper limit threshold, the third valve 22 is closed to stop the water from being injected into the water storage device 12.

[0200] It should be noted that after the water purifier 19 filters the water using a filter, the water flows out through the purified water outlet 21 to ensure that the water flowing into the water storage device 12 meets the water quality requirements.

[0201] In this embodiment, when the water storage volume is less than the upper limit threshold, the third valve 22 is opened to inject water into the water storage device 12, thus avoiding insufficient water storage when mixing is required, and demonstrating a high degree of intelligence.

[0202] In one embodiment, the control method of the water purification protection device 11 further includes: adjusting the opening of the third valve 22 to zero in response to the water storage reaching the upper limit threshold.

[0203] When the water storage capacity is equal to the upper limit threshold of the water volume, the water storage capacity can meet the needs of mixing water, and there is no need to inject water into the water storage device 12. Therefore, the opening of the third valve 22 needs to be adjusted to zero, that is, the third valve 22 is controlled to close, and the water injection into the water storage device 12 is stopped.

[0204] In this embodiment, when the water storage volume is equal to the upper limit threshold of the water volume, the opening of the third valve 22 is adjusted, and the water supply to the water storage device 12 is automatically stopped when the water is full, so as to realize intelligent management and avoid water waste.

[0205] In one embodiment, the water purification protection device 11 further includes a filter device 23, which is disposed in the water storage device 12. Water flowing out through the first end of the mixing pipe 13 is filtered by the filter device 23 and then flows out through the second end of the mixing pipe 13.

[0206] Considering that the water is more prone to bacteria and scale growth when the temperature inside the inlet pipe 18 is too high, and the resulting impurities will enter the water purifier 19, which will have an adverse effect on the water purifier 19, such as affecting the service life and water purification effect of the water purifier 19, a filtration module is set up so that the water flowing out from the first end of the mixing pipe 13 can be filtered by the filtration device 23 and then flow out from the second end of the mixing pipe 13.

[0207] The filter device 23 is mainly used to filter out scale and bacteria. The filter element of the filter device 23 can be set according to the actual situation, and no special limitation is made here.

[0208] In this embodiment, the water in the mixing pipe 13 is filtered by the filtration device 23, which improves the water quality of the water entering the water purifier 19, reduces the wear on the filter of the water purifier 19, and extends the service life of the water purifier 19.

[0209] In one embodiment, the water purification protection device 11 further includes a sterilization device, which is disposed in the water storage device 12 and is electrically connected to the controller.

[0210] The control method of the water purification protection device 11 also includes: in response to the water storage time in the water storage device 12 exceeding the preset time, activating the sterilization device of the water storage device 12, and activating the sterilization device after the sterilization time is reached.

[0211] If the water in the water storage device 12 is stored for a longer than preset time, the water quality will deteriorate. To prevent this, the controller activates the water storage device 12 to sterilize the water after the preset storage time has elapsed. Once the sterilization time has been reached, sterilization is complete, the water quality in the water storage device 12 meets the requirements, and the sterilization device is shut off, thus reducing unnecessary energy consumption.

[0212] The preset time and sterilization duration can be set according to the actual situation, and no special limit is set here.

[0213] In this embodiment, after the storage time exceeds the preset time, the water in the water storage device 12 is sterilized to remove or reduce microbial pollution in the water and improve water quality. After the sterilization time is reached, the sterilization device is turned off. When the water quality meets the requirements, turning off the sterilization device can meet actual needs, avoid resource waste, and save energy.

[0214] In one embodiment, the water purification protection device 11 further includes an alarm, with the liquid level sensor and the first temperature sensor 17 respectively electrically connected to the alarm.

[0215] The control method of the water purification protection device 11 also includes: in response to the water storage volume being less than the lower limit threshold and the inlet water temperature being greater than the temperature threshold, the alarm will issue a prompt to suspend use.

[0216] When the inlet water temperature collected by the first temperature sensor 17 is greater than the temperature threshold, the water in the water storage device 12 needs to be mixed to cool it down. However, the water storage volume collected by the liquid level sensor at this time is less than the lower limit threshold of water volume. The water storage volume is insufficient and therefore the mixing effect cannot be guaranteed. In order to ensure that hot water with a temperature greater than the temperature threshold does not flow into the water purifier 19, the alarm issues a prompt to stop using the water purifier 19 to remind the user to stop using the water purifier 19.

[0217] When the inlet water temperature is below the temperature threshold or the water storage volume is above the lower water volume threshold, the alarm will sound a prompt to resume use. If the inlet water temperature is below the temperature threshold, it means that mixing is not required, and the water temperature entering the water purifier 19 is within the target temperature range. If the water storage volume is above the lower water volume threshold, it means that the storage volume is sufficient to achieve mixing, ensuring that the water temperature entering the water purifier 19 is within the target temperature range. Since hot water above the temperature threshold will not flow into the water purifier 19, the alarm will sound a prompt to resume use, reminding the user that the water purifier 19 can be used.

[0218] In this embodiment, when the inlet water temperature is greater than the temperature threshold and the water storage volume is less than the lower limit threshold, the alarm will issue a prompt to suspend use, so as to prevent hot water from flowing into the water purifier 19 due to user use, and to prevent bacteria and scale from growing in the water due to high temperature, thereby improving the service life of the water purifier 19.

[0219] In one embodiment, the water storage device 12 has a turbulent flow structure 24.

[0220] The turbulence structure 24 is used to lengthen the path of water flowing into and out of the water storage device 12. With the turbulence structure 24, the water flow in the water storage device 12 can be abstractly regarded as flowing in an S-shape, disturbing the water flow inside the water storage device 12. Without the turbulence structure 24, water would flow directly out after entering the water storage device 12, and some water would remain in the water storage device 12 for a long time, thus affecting the water quality.

[0221] The location and number of turbulence structures 24 can be set according to actual conditions and are not specifically limited here. Turbulence structures 24 include, but are not limited to, baffles. Perforations may be made on the baffles to appropriately reduce water flow resistance. The number and location of the perforations can be set according to actual conditions and are not specifically limited here.

[0222] In this embodiment, the water storage device 12 has a turbulent flow structure 24, which can disturb the water flow inside the water storage device 12 and prevent some water from remaining in the water storage device 12 for a long time, thus avoiding affecting the water quality.

[0223] In one embodiment, the water storage device 12 is equipped with a water pump.

[0224] When the inlet water temperature exceeds the temperature threshold and water mixing for cooling is required, a water pump is used to direct the water in the storage device 12 to the third inlet, thus achieving water mixing. The number, location, and type of water pumps can be set according to actual conditions and are not specifically limited here.

[0225] In this embodiment, the water storage device 12 is equipped with a water pump, which can overcome gravity and lift the water in the water storage device 12 to a higher position than the water storage device 12, and deliver it to the third water inlet of the second valve, thereby enhancing the reliability and flexibility of water mixing.
