[0064] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0065] Please refer to Figure 1-4 This application provides a water purifier 001, which includes a housing assembly 10, a controller, a faucet 1A, a hot water system 004, and a water purification system 003.

[0066] The housing assembly 10 has an inner cavity 10A, in which the hot water system 004 and the water purification system 003 are both installed. The housing assembly 10 protects the hot water system 004 and the water purification system 003, reducing the probability of damage to these systems. It is understood that the housing assembly 10 can be made of at least one of metal and plastic. For example, the housing assembly 10 can be made of metal to give it high structural strength, reducing the probability of damage and consequently reducing the probability of damage to the hot water system 004 and the water purification system 003, thus extending the service life of the water purifier 001. Alternatively, the housing assembly 10 can be made of plastic, which reduces weight and material costs while ensuring structural strength.

[0067] The faucet 1A is connected to the housing assembly 10 and is also connected to the hot water system 004 and the water purification system 003. When the faucet 1A is turned on, hot water from the hot water system 004 or room temperature water from the water purification system 003 can flow out through the faucet 1A to provide hot or room temperature water to the user. It is understood that the water purifier 001 can have two faucets 1A, one connected to the hot water system 004 and the other connected to the water purification system 003, thus providing hot and room temperature water to the user independently. In other embodiments, the faucet 1A can also be connected to both the hot water system 004 and the water purification system 003, and the flow of hot or room temperature water can be controlled by a switch.

[0068] It is understandable that faucet 1A can also be a smart faucet 1A. When the controller detects a signal for drawing room temperature water or a water replenishment signal from the hot water system 004 at the smart faucet 1A, the controller can control the water purification system 003 to start water production, so as to ensure that users can get room temperature water and hot water from the smart faucet 1A in a timely manner, reduce the user's waiting time, and improve the user experience.

[0069] The hot water system 004 includes a hot water tank assembly 20, which is connected to a water tap 1A and a water purification system 003. It can heat room temperature water filtered by the water purification system 003 and provide hot water to the user after the water tap 1A is turned on.

[0070] The water purification system 003 can be connected to the raw water source. When the controller detects a signal for drawing room temperature water from faucet 1A or a water replenishment signal from the heating tank assembly 20, it controls the water purification system 003 to start water production. When these two signals disappear, the controller controls the water purification system 003 to stop water production and enter standby mode. The room temperature water from the outlet of the water purification system 003 can enter the heating tank assembly 20 or flow directly out through faucet 1A.

[0071] Please refer to Figure 1-4 Specifically, the water purification system 003 may include a filtration system 50; the inlet of the filtration system 50 is connected to the inlet of the water purification system 003, and the outlet of the filtration system 50 is connected to the outlet of the water purification system 003; the filtration system 50 may include multiple filter elements, which may be set independently or integrated into a composite filter element.

[0072] Please refer to Figure 1-4 More specifically, the filtration system 50 may include a primary filter element and a secondary filter element. The primary filter element may be a pre-filter element 52, and the secondary filter element may be a reverse osmosis filter element 53. The inlet of the pre-filter element 52 is connected to the inlet of the filtration system 50, the outlet of the pre-filter element 52 is connected to the inlet of the reverse osmosis filter element 53, and the outlet of the reverse osmosis filter element 53 is connected to the outlet of the filtration system 50.

[0073] The pre-filter 52 is used to perform preliminary filtration of raw water, which can filter out large particles such as mud, rust, insect eggs, and red worms. The raw water can be tap water, well water, etc. The pre-filter 52 can be a PP cotton filter (polypropylene melt-blown filter), carbon rod filter, composite filter, etc.

[0074] The reverse osmosis filter element 53 has a reverse osmosis membrane, which can be an artificial semi-permeable membrane. The membrane pore size of the reverse osmosis membrane is very small, which can effectively remove impurities such as dissolved salts, colloids, microorganisms, and organic matter from the water. A pure water pipe is connected between the reverse osmosis filter element 53 and the faucet 1A1, so that the user of this application can obtain pure water, i.e., room temperature water, after filtration by the reverse osmosis filter element 53 through the faucet 1A.

[0075] Please refer to Figure 1-4 In order to facilitate the removal of impurities removed by the filtration system 50, the water purification system 003 also includes a wastewater drainage pipe 54. The wastewater drainage pipe 54 includes a wastewater drainage pipe 541 and a wastewater valve 542. The wastewater drainage pipe 541 is connected to the wastewater outlet of the filtration system 50, and the wastewater valve 542 is installed on the wastewater drainage pipe 541. The wastewater valve 542 is used to control the discharge of wastewater.

[0076] In other embodiments, the filtration system 50 may further include a post-filter cartridge, the inlet of which is connected to the outlet of the reverse osmosis filter cartridge 53, and the outlet of which is connected to the outlet of the filtration system 50. The post-filter cartridge is used to adsorb odors and residual chlorine, and can be used to improve the taste of room temperature water. The post-filter cartridge may be an activated carbon filter cartridge. It is understood that the pre-filter cartridge 52 and the post-filter cartridge can be integrated into a single-stage filter cartridge, so that when the user replaces the single-stage filter cartridge, both the pre-filter cartridge 52 and the post-filter cartridge can be replaced simultaneously, thereby improving filter cartridge replacement efficiency.

[0077] It is understood that the wastewater drain pipe 54 can be connected to the wastewater outlet of the pre-filter 52 and the wastewater outlet of the reverse osmosis filter 53. In other embodiments, the wastewater drain pipe 54 may also be connected only to the wastewater outlet of the reverse osmosis filter 53.

[0078] It is understood that, in the embodiments of this application, the filtration system 50 may also include only the reverse osmosis filter element 53, which is used to filter impurities in the water in one step to provide pure water to the user.

[0079] Please refer to Figure 1-4 Furthermore, since the reverse osmosis filter element 53 has working water pressure requirements, the water purification system 003 also includes a booster pipe 55. The inlet of the booster pipe 55 is connected to the inlet of the water purification system 003, or to the inlet of the water purification system 003 through the pre-filter element 52. The outlet of the booster pipe 55 is connected to the inlet of the reverse osmosis filter element 53.

[0080] Please refer to Figure 1-4 Specifically, the booster pipeline 55 includes a booster water pipe 551 and a booster pump 552. The inlet of the booster water pipe 551 is connected to the inlet of the booster pipeline 55, and the outlet of the booster water pipe 551 is connected to the outlet of the booster pipeline 55. The booster pump 552 is installed on the booster water pipe 551. The booster pump 552 can increase the water pressure to the operating pressure range required by the reverse osmosis membrane, ensuring that the reverse osmosis membrane can work normally and achieve stable water production and good filtration effect.

[0081] Please refer to Figure 1-4 To facilitate the water supply from the outlet of the water purification system 003 to the heating tank assembly 20 and to directly provide room temperature water to the faucet 1A, the hot water system 004 also includes a water supply pipe 25 and a water supply valve 251 installed on the water supply pipe 25. The water supply pipe 25 connects the outlet of the water purification system 003 and the heating tank assembly 20, and the water supply valve 251 is installed on the water supply pipe 25. When the heating tank assembly 20 needs water, the water supply valve 251 opens, allowing room temperature water from the outlet of the water purification system 003 to enter the heating tank assembly 20. When the user needs room temperature water, the water supply valve 251 closes, allowing room temperature water from the outlet of the water purification system 003 to flow out through the faucet 1A. Of course, the water supply valve 251 can also be opened when the user needs room temperature water, meaning that the water purification system 003 can simultaneously meet the needs of producing room temperature water and supplying water to the heating tank assembly 20.

[0082] Please refer to Figure 1-4 It is understandable that the faucet 1A can also be installed near the control panel and connected to the hot water tank assembly 20 and the water purification system 003 through a pipeline, so that the user can control the water output of the faucet 1A through the control panel, thereby facilitating the use of hot water and room temperature water from the faucet 1A.

[0083] Please refer to Figure 1-4 It is understandable that the water purifier 001 may also include a water dispenser 57, where room temperature water can enter the water dispenser 57 after passing through a one-way valve, thus supplying water to the water dispenser 57.

[0084] However, when the inlet of the water purification system 003 is directly connected to the raw water, if the raw water is hard water rich in calcium and magnesium ions, the direct entry of the hard water rich in calcium and magnesium ions into the water purification system 003 will cause a large accumulation of calcium and magnesium ions at the filter element, affecting the normal service life of the filter element.

[0085] Please refer to Figure 1-4Based on the above issues, the water purifier 001 may also include a water softening system 002, which is also located within the housing assembly 10. The inlet of the water softening system 002 is used to connect to raw water, and the outlet of the water softening system 002 is connected to the inlet of the water purification system 003. The water softening system 002 can soften hard water rich in calcium and magnesium ions into soft water. In other words, the water softening system 002 can adsorb calcium and magnesium ions in hard water, so that the outlet of the water softening system 002 outputs soft water. The soft water enters the water purification system 003, which can reduce the probability of calcium and magnesium ions accumulating in large quantities at the filter element, thus ensuring that the filter element has a normal service life.

[0086] Please refer to Figure 1-4 Specifically, the water softening system 002 includes a water softening valve 020, a resin tank 010, and a brine tank 030. The water softening valve 020 is connected to the inlet and outlet of the water softening system 002, as well as to the resin tank 010 and the brine tank 030, and is connected to a controller. The resin tank 010 is used to soften hard water into soft water. The brine tank 030 is used to store regenerated salt, which can enter the resin tank 010 through the water softening valve 020 to regenerate the resin in the resin tank 010.

[0087] Please refer to Figure 4 When the soft water mode is activated, the controller can control the soft water valve 020 to connect the inlet of the soft water system 002 and the resin tank 010, and connect the outlet of the resin tank 010 and the outlet of the soft water system 002. At this time, hard water can enter the resin tank 010 through the soft water valve 020. The sodium ions on the resin in the resin tank 010 can exchange with the calcium and magnesium ions in the hard water, thereby adsorbing the calcium and magnesium ions, turning the hard water into soft water, and storing it in the resin tank 010. When a user takes pure water from faucet 1A, the soft water in resin tank 010 can flow out through the outlet of soft water valve 020 and enter the water purification system 003. After being filtered by the water purification system 003, the soft water can be directly output to faucet 1A to provide the user with room temperature pure water. After being filtered by the water purification system 003, the soft water can also be output to the heating tank assembly 20 or the water dispenser 57 for heating, and then output to faucet 1A through the heating tank assembly 20 to provide the user with hot water, or directly provide the user with hot water through the water dispenser 57.

[0088] When all sodium ions on the resin are converted into calcium and magnesium ions, the resin reaches saturation. At this point, the resin loses its ability to soften hard water, and the controller can control the soft water system 002 to start the regeneration mode. It is understood that the controller can control the soft water system 002 to start the regeneration program at preset intervals to regenerate the resin, thereby ensuring that users can access soft water. For example, the preset interval can be 12 hours, 24 hours, 36 hours, etc. In this embodiment, no specific limitation is made to the preset interval.

[0089] Please refer to Figure 4 When the regeneration mode is activated, the controller controls the soft water valve 020 to disconnect the resin tank 010 from the outlet of the soft water system 002, and controls the soft water valve 020 to connect both the inlet and outlet of the soft water system 002. The controller also controls the soft water valve 020 to connect the resin tank 010 to the brine tank 030. At this time, hard water enters the resin tank 010 through the soft water valve 020, and then flows from the resin tank 010 into the brine tank 030. After entering the brine tank 030, the water in the resin tank 010 comes into contact with the regenerated salt in the brine tank 030, dissolving the regenerated salt to form brine. The soft water valve 020 can draw the brine from the brine tank 030 into the resin tank 010, using sodium ions in the brine to replace calcium and magnesium ions on the resin, thereby restoring the resin's softening ability. It is understood that in other embodiments, raw water can be directly injected into the salt tank 030 through the soft water valve 020 to dissolve the regenerated salt and form brine. The soft water valve 020 then draws the brine from the salt tank 030 into the resin tank 010, so that the sodium ions in the brine can replace the calcium and magnesium ions on the resin, thereby restoring the resin's softening ability.

[0090] In this embodiment, in addition to the controller being able to control the soft water system 002 to start the regeneration program at preset intervals, it is also possible to determine whether the regeneration mode needs to be started by detecting the liquid level in the resin tank 010.

[0091] Please refer to Figure 2 and Figure 4 Specifically, the soft water system 002 also includes a soft water level sensor 060, which is installed in the resin tank 010 and connected to a controller. The controller can obtain the soft water level of the resin tank 010 through the soft water level sensor 060. When the soft water level is lower than a first preset level, the controller controls the soft water valve 020 to start the regeneration mode. Exemplarily, the soft water level sensor 060 includes, but is not limited to, at least one of a float-type water level sensor, a static pressure water level sensor, a probe-type water level sensor, a Hall effect water level sensor, an ultrasonic water level sensor, a photoelectric water level sensor, and a radar water level sensor. In this embodiment, the specific form of the soft water level sensor 060 is not limited.

[0092] Please refer to Figure 2 and Figure 4 When the regeneration mode is activated, the soft water valve 020 is not connected to the outlet of the resin tank 010 and the soft water system 002. When the soft water mode is deactivated, the soft water valve 020 is not connected to the outlet of the resin tank 010 and the soft water system 002. In order to facilitate the use of the water purifier 001 by the user during this period, the controller can control the soft water valve 020 to connect to the inlet and outlet of the soft water system 002, so that hard water can be directly output through the outlet of the soft water valve 020 to enter the water purification system 003.

[0093] Please refer to Figure 2 and Figure 5 In other embodiments, the soft water system 002 may further include a soft water bypass pipe 090, which is connected to the inlet and outlet of the soft water system 002. When the regeneration mode is started, the controller controls the soft water valve 020 to disconnect the resin tank 010 from the outlet of the soft water system 002, and controls the soft water bypass pipe 090 to open, so that the inlet and outlet of the soft water system 002 can be connected through the soft water bypass pipe 090, and the outlet of the soft water system 002 outputs hard water. When the soft water mode is stopped, the controller controls the soft water valve 020 to disconnect the resin tank 010 from the outlet of the soft water system 002, and controls the soft water bypass pipe 090 to open, so that the inlet and outlet of the soft water system 002 can be connected through the soft water bypass pipe 090, and the outlet of the soft water system 002 outputs hard water.

[0094] Please refer to Figure 2 and Figure 5 Specifically, the soft water bypass pipeline 090 includes a soft water bypass pipe 091 and a soft water bypass valve 092. The soft water bypass pipe 091 connects the inlet and outlet of the soft water system 002. The soft water bypass valve 092 is installed on the soft water bypass pipe 091 and is connected to the controller. When the regeneration mode is activated, the controller controls the soft water valve 020 to disconnect the resin tank 010 from the outlet of the soft water system 002, and controls the soft water bypass valve 092 to open, so that the inlet and outlet of the soft water system 002 can be connected through the soft water bypass pipe 091, allowing the outlet of the soft water system 002 to output hard water. When the soft water mode is deactivated, the controller controls the soft water valve 020 to disconnect the resin tank 010 from the outlet of the soft water system 002, and controls the soft water bypass valve 092 to open, so that the inlet and outlet of the soft water system 002 can be connected through the soft water bypass pipe 091, allowing the outlet of the soft water system 002 to output hard water.

[0095] Please refer to Figure 2 and Figure 6To reduce the impact of hard water rich in calcium and magnesium ions directly entering the water purification system 003 on the normal service life of the filter element, in a specific embodiment, the wastewater drainage pipe 54 may include an adjustable wastewater valve 543. The adjustable wastewater valve 543 is disposed on the wastewater drainage pipe 541 and is connected to a controller. The adjustable wastewater valve 543 has at least a closed state, a first open state, and a second open state. When the adjustable wastewater valve 543 is in the closed state, the wastewater drainage pipe 541 stops discharging wastewater. When the adjustable wastewater valve 543 is in the first open state, the wastewater drainage pipe 541 discharges wastewater at a first wastewater discharge rate. When the adjustable wastewater valve 543 is in the second open state, the wastewater drainage pipe 541 discharges wastewater at a second wastewater discharge rate, and the second wastewater discharge rate is greater than the first wastewater discharge rate.

[0096] Please refer to Figure 2 and Figure 6 When the regeneration mode is started or the soft water mode is turned off, the outlet of the soft water system 002 outputs hard water. The controller can control the adjustable wastewater valve 543 to switch from the first open state to the second open state, thereby increasing the wastewater discharge of the wastewater drain pipe 541. This allows a large amount of wastewater generated by the filtration system 50 to be discharged through the wastewater drain pipe 541, meaning that wastewater rich in calcium and magnesium ions can be discharged through the wastewater drain pipe 541. This reduces the concentration difference of the liquid on both sides of the reverse osmosis membrane, thereby reducing the filtration pressure on the reverse osmosis membrane, reducing the consumption of the reverse osmosis membrane, and allowing the reverse osmosis membrane to reach its normal service life, thus improving the user experience.

[0097] Please refer to Figure 2 and Figure 7 In another specific embodiment, the booster pipeline 55 further includes a variable frequency booster pump 553, which is disposed on the booster water pipe 551 and connected to the controller. The variable frequency booster pump 553 has at least a first booster state and a second booster state. When the variable frequency booster pump 553 is in the first booster state, the water pressure in the booster water pipe 551 is the first water pressure. When the variable frequency booster pump 553 is in the second booster state, the water pressure in the booster water pipe 551 is the second water pressure, and the second water pressure is greater than the first water pressure.

[0098] Please refer to Figure 2 and Figure 7 When the regeneration mode is started or the soft water mode is turned off, the outlet of the soft water system 002 outputs hard water. The controller can control the variable frequency booster pump 553 to switch from the second booster state to the first booster state, thereby reducing the water pressure in the booster water pipe 551. This reduces the rate at which salt and impurities in the water concentrate and accumulate on the surface of the reverse osmosis membrane, reducing the impact on the service life of the reverse osmosis filter element 53, so that the reverse osmosis membrane can reach its normal service life and improve the user experience.

[0099] Please refer to Figure 2 and Figure 4 In one embodiment, the soft water system 002 further includes a salinity sensor 050, which is located in the salt tank 030 and connected to a controller. The controller can obtain the detected salinity level of the salt tank 030 through the salinity sensor 050. Before the regeneration mode is started, the controller obtains the detected salinity level of the salt tank 030 through the salinity sensor 050. When the detected salinity level is lower than the preset salinity level, it indicates that the amount of regenerated salt in the salt tank 030 is insufficient to complete one regeneration cycle. At this time, the controller can control the prompting device to inform the user that the amount of regenerated salt in the salt tank 030 is low, and control the soft water valve 020 to disconnect the resin tank 010 from the outlet of the soft water system 002, and control the soft water valve 020 to connect the inlet and outlet of the soft water system 002, so that the outlet of the soft water system 002 outputs hard water. The controller also controls the wastewater drainage pipe 54 to increase the wastewater discharge to protect the filtration system 50. It is understood that the prompting device includes a buzzer, indicator light, display icon, etc. In other embodiments, the prompting device may also take other forms. In the embodiments of this application, the specific form of the prompting device is not limited.

[0100] Please refer to Figure 2 and Figure 4 In one embodiment, the water purifier 001 further includes a water level sensor, which is disposed in the inner cavity 10A and connected to the controller. The controller can obtain the water level in the inner cavity 10A through the water level sensor. When the water level in the inner cavity 10A reaches a second preset level as determined by the controller through the water level sensor, it indicates that there is a water leak in the internal water circuit of the water purifier 001. At this time, the controller can control the prompting device to notify the user that the water purifier 001 is leaking water and control the outlet of the soft water system 002 to close, so as to reduce further water leakage of the water purifier 001.

[0101] Please refer to Figure 6-9 This application also provides a control method for a water purifier 001, including:

[0102] Step S100: When the regeneration mode is started, or when the soft water mode is stopped, or when an abnormal signal is detected, control the soft water system 002 to output hard water.

[0103] In this embodiment, when the regeneration mode is activated, when the soft water mode is stopped, or when the controller detects an abnormal signal, the controller controls the soft water valve 020 to disconnect the resin tank 010 from the outlet of the soft water system 002, so that the outlet of the soft water system 002 outputs hard water. Specifically, the controller can control the connection between the inlet and outlet of the soft water valve 020 so that the outlet of the soft water system 002 can output hard water. The controller can also control the soft water bypass valve 092 to open so that the inlet and outlet of the soft water system 002 can be connected via the soft water bypass pipe 091, so that the outlet of the soft water system 002 outputs hard water.

[0104] The abnormal signals detected by the controller include abnormal signals from the soft water valve 020, other than blockage between the inlet and outlet of the soft water valve 020.

[0105] Step S200: Control the wastewater drainage pipe 54 to increase the wastewater discharge to protect the filtration system 50.

[0106] In this embodiment, the controller can control the adjustable wastewater valve 543 to switch from a first open state to a second open state, thereby increasing the wastewater discharge capacity of the wastewater drain pipe 541. This allows a large amount of wastewater generated by the filtration system 50 to be discharged through the wastewater drain pipe 541, meaning that wastewater rich in calcium and magnesium ions can be discharged through the wastewater drain pipe 541. This reduces the concentration difference of the liquid on both sides of the reverse osmosis membrane, thereby reducing the filtration pressure on the reverse osmosis membrane, reducing the consumption of the reverse osmosis membrane, and enabling the reverse osmosis membrane to reach its normal service life, thus improving the user experience.

[0107] Step S300: Control the water pressure in the booster pipe 55 to reduce it in order to protect the filtration system 50.

[0108] In this embodiment, the controller can control the variable frequency booster pump 553 to switch from the second booster state to the first booster state, thereby reducing the water pressure in the booster water pipe 551. This reduces the rate at which salt and impurities in the water concentrate and accumulate on the surface of the reverse osmosis membrane, thus reducing the impact on the service life of the reverse osmosis filter element 53. This allows the reverse osmosis membrane to reach its normal service life and improves the user experience.

[0109] It is understandable that steps S200 and S300 can be selectively executed after step S100, and the method steps for drinking can be selected according to the actual product design.

[0110] Please refer to Figure 6 and Figure 10 In one embodiment, step S200 includes:

[0111] Step S210: Control the adjustable wastewater valve 543 to increase the wastewater discharge rate, thereby increasing the wastewater discharge rate of the wastewater drain pipe 541 to protect the filtration system 50.

[0112] In this embodiment, the controller can control the adjustable wastewater valve 543 to switch from a first open state to a second open state, thereby increasing the wastewater discharge capacity of the wastewater drain pipe 541. This allows a large amount of wastewater generated by the filtration system 50 to be discharged through the wastewater drain pipe 541, meaning that wastewater rich in calcium and magnesium ions can be discharged through the wastewater drain pipe 541. This reduces the concentration difference of the liquid on both sides of the reverse osmosis membrane, thereby reducing the filtration pressure on the reverse osmosis membrane, reducing the consumption of the reverse osmosis membrane, and enabling the reverse osmosis membrane to reach its normal service life, thus improving the user experience.

[0113] Please refer to Figure 7 and Figure 11 In one embodiment, step S300 includes:

[0114] Step S310: Control the speed of the variable frequency booster pump 553 to reduce the water pressure in the booster water pipe 551, thereby protecting the filtration system 50.

[0115] In this embodiment, the controller can control the variable frequency booster pump 553 to switch from the second booster state to the first booster state, thereby reducing the water pressure in the booster water pipe 551. This reduces the rate at which salt and impurities in the water concentrate and accumulate on the surface of the reverse osmosis membrane, thus reducing the impact on the service life of the reverse osmosis filter element 53. This allows the reverse osmosis membrane to reach its normal service life and improves the user experience.

[0116] Please refer to Figure 6 , Figure 7 and Figure 12 In one embodiment, step S100 includes:

[0117] Step S110: When the regeneration mode is started, control the soft water valve 020 to not connect the resin tank 010 and the outlet of the soft water system 002, and control the soft water valve 020 to connect the inlet and outlet of the soft water system 002, so that the outlet of the soft water system 002 outputs hard water.

[0118] In this embodiment, when the regeneration mode is activated, the controller controls the soft water valve 020 to disconnect the resin tank 010 from the outlet of the soft water system 002. In order to facilitate the user's use of the water purifier 001 during this period, the controller can control the soft water valve 020 to connect the inlet and outlet of the soft water system 002, so that hard water can be directly output through the outlet of the soft water valve 020 to enter the water purification system 003, so that the user can still take water from the tap 1A when the regeneration mode is activated.

[0119] It is understood that in other embodiments, when the regeneration mode is started, the controller can also control the soft water bypass valve 092 to open, so that the inlet and outlet of the soft water system 002 can be connected through the soft water bypass pipe 091. Similarly, the outlet of the soft water system 002 can output hard water to enter the water purification system 003, so that when the regeneration mode is started, the user can still take water from the faucet 1A.

[0120] Step S120: When the soft water mode stops, control the soft water valve 020 to disconnect the resin tank 010 from the outlet of the soft water system 002, and control the soft water valve 020 to connect the inlet and outlet of the soft water system 002, so that the outlet of the soft water system 002 outputs hard water.

[0121] In this embodiment, when the soft water mode is stopped, the soft water valve 020 is not connected to the resin tank 010 and the outlet of the soft water system 002. In order to facilitate the user's use of the water purifier 001 during this period, the controller can control the soft water valve 020 to connect to the inlet and outlet of the soft water system 002, so that hard water can be directly output through the outlet of the soft water valve 020 to enter the water purification system 003, so that the user can still take water from the faucet 1A when the soft water mode is stopped.

[0122] It is understood that in other embodiments, when the soft water mode is stopped, the controller can also control the soft water bypass valve 092 to open, so that the inlet and outlet of the soft water system 002 can be connected through the soft water bypass pipe 091. Similarly, the outlet of the soft water system 002 can output hard water to enter the water purification system 003, so that when the regeneration mode is started, the user can still take water from the faucet 1A.

[0123] Step S130: When an abnormal signal is detected, control the soft water valve 020 to disconnect the resin tank 010 from the outlet of the soft water system 002, and control the soft water valve 020 to connect the inlet and outlet of the soft water system 002, so that the outlet of the soft water system 002 outputs hard water.

[0124] In this embodiment, when the controller detects an abnormal signal, the controller controls the soft water valve 020 to disconnect the resin tank 010 from the outlet of the soft water system 002. In order to facilitate the user's use of the water purifier 001 during this period, the controller can control the soft water valve 020 to connect the inlet and outlet of the soft water system 002, so that hard water can be directly output through the outlet of the soft water valve 020 to enter the water purification system 003, so that the user can still take water from the tap 1A when the controller detects an abnormal signal.

[0125] It is understood that in other embodiments, when the controller detects an abnormal signal, the controller can also control the soft water bypass valve 092 to open, so that the inlet and outlet of the soft water system 002 can be connected through the soft water bypass pipe 091. Similarly, the outlet of the soft water system 002 can output hard water to enter the water purification system 003, so that when the regeneration mode is started, the user can still take water from the faucet 1A.

[0126] Please refer to Figure 6 , Figure 7 and Figure 13 In one embodiment, step S130 includes:

[0127] Step S131: Before starting the regeneration mode, the salt level of the salt tank 030 is obtained through the salt level sensor 050.

[0128] In this embodiment of the application, before the regeneration mode is started, the controller obtains the detected salt level of the salt tank 030 through the salt level sensor 050.

[0129] Step S132: When an abnormal signal indicating that the salt level is lower than the preset salt level is detected, the soft water valve 020 is controlled to connect the inlet and outlet of the soft water system 002, and the soft water valve 020 is controlled to disconnect the resin tank 010 from the outlet of the soft water system 002, so that the outlet of the soft water system 002 outputs hard water.

[0130] In this embodiment, when the controller detects an abnormal signal indicating that the salt level is lower than the preset salt level, it indicates that the amount of regenerated salt in the salt tank 030 is insufficient to complete one regeneration cycle. At this time, the controller can control the prompting device to alert the user that the amount of regenerated salt in the salt tank 030 is low, and control the soft water valve 020 to disconnect the resin tank 010 from the outlet of the soft water system 002. The controller also controls the soft water valve 020 to connect the inlet and outlet of the soft water system 002, causing the outlet of the soft water system 002 to output hard water. The controller also controls the wastewater drainage pipe 54 to increase the wastewater discharge rate to protect the filtration system 50. It is understood that the prompting device includes a buzzer, indicator light, display icon, etc. In other embodiments, the prompting device may take other forms; however, in this embodiment, the specific form of the prompting device is not limited.

[0131] Please refer to Figure 6 , Figure 7 and Figure 14 In one embodiment, step S130 further includes:

[0132] Step S133: Before starting the regeneration mode, obtain the status of the soft water valve 020.

[0133] In this embodiment of the application, the controller can obtain the status of the soft water valve 020 before the regeneration mode is started.

[0134] Step S134: When an abnormal signal other than blockage between the inlet and outlet of the soft water valve 020 is detected, the controller can control the soft water valve 020 to disconnect the resin tank 010 from the outlet of the soft water system 002, and control the soft water valve 020 to connect the inlet and outlet of the soft water system 002, so that the outlet of the soft water system 002 outputs hard water.

[0135] In this embodiment, when the controller detects an abnormal signal in the soft water valve 020 other than a blockage between the inlet and outlet of the soft water valve 020, the controller can control the soft water valve 020 to disconnect the resin tank 010 from the outlet of the soft water system 002, and control the soft water valve 020 to connect both the inlet and outlet of the soft water system 002, so that the outlet of the soft water system 002 outputs hard water. In other embodiments, the controller can also control the inlet of the soft water valve 020 to be closed.

[0136] Please refer to Figure 6 , Figure 7 and Figure 15 In one embodiment, the control method further includes:

[0137] S400 When the soft water level is lower than the first preset water level, control the soft water valve 020 to connect the inlet of the soft water system 002 to the resin tank 010, and control the soft water valve 020 to connect the resin tank 010 to the brine tank 030 to start the regeneration mode.

[0138] In this embodiment of the application, when the soft water level is lower than the first preset water level, it indicates that the amount of soft water in the resin tank 010 is low. The controller controls the soft water valve 020 to connect the inlet of the soft water system 002 to the resin tank 010, and controls the soft water valve 020 to connect the resin tank 010 to the salt tank 030, so as to start the regeneration mode.

[0139] Please refer to Figure 6 , Figure 7 and Figure 16 In one embodiment, the control method further includes:

[0140] S500 When the leakage water level reaches the second preset water level, the outlet of the soft water system 002 is closed.

[0141] In this embodiment, when the controller detects that the water level in the inner cavity 10A has reached the second preset level via the water level sensor, it indicates that there is a leak in the internal water circuit of the water purifier 001. At this time, the controller can control the prompting device to notify the user that the water purifier 001 is leaking, and control the outlet of the soft water system 002 to close, so as to reduce further leakage of the water purifier 001. In other embodiments, the controller can also control the inlet of the soft water valve 020 to close, which will not be elaborated further in this embodiment.

[0142] Please refer to Figure 6 , Figure 7 and Figure 17 In one embodiment, the control method further includes:

[0143] S600 When an abnormal signal indicating blockage between the inlet and outlet of the soft water valve 020 is detected, the outlet of the soft water system 002 is closed.

[0144] In this embodiment, when the controller detects an abnormal blockage signal between the inlet and outlet of the soft water valve 020, the controller controls the outlet of the soft water system 002 to close, thereby reducing the probability of damage to the soft water valve 020. The controller can also control a notification device to send a notification message to the user so that the user is aware of the abnormal situation. In other embodiments, the controller can also control the inlet of the soft water valve 020 to close; however, this will not be elaborated upon in this embodiment.
