Description

Technical Field

[0001] This application relates to the field of water supply equipment technology, and in particular to a control method for a water purifier and a water purifier. Background Technology

[0002] Currently, there are some countertop water purifiers on the market with external heating devices such as electric kettles and health pots. Tap water is filtered by the purifier to produce clean water, which is then heated by the external heating device. Users can use the external heating device to brew tea, boil tea, stew health-preserving ingredients, etc., which is very convenient for users.

[0003] Patent CN207286826U relates to a water purifier with a filter replacement reminder function. The raw water from the filter pitcher is filtered through the filter cartridge. By opening the bottom stop valve of the pitcher and then the stop valve on the pitcher base, the purified water enters a water tank located inside the pitcher base. A water pump then supplies the purified water from the tank to the water purifier body, which then provides drinking water to the user. However, this method requires the user to manually add water to the heating element, resulting in a long waiting time and a poor user experience. Summary of the Invention

[0004] This application provides a control method and a water purifier for a water purifier. The water purifier automatically replenishes water to the heating device and the purified water tank simultaneously using a water pump, thereby reducing the waiting time for the user when replenishing water to the heating device.

[0005] In a first aspect, a control method for a water purifier is provided, comprising: rinsing the filter assembly of the water purifier in response to an activation command; if the water tank of the water purifier is in an installed state and the water level in the water tank has not reached a target water level, using the filter assembly to produce water and delivering the produced water to the water tank; determining whether the heating device is in a heating position in response to a heating command for the heating device of the water purifier; if the heating device is in the heating position and the liquid level in the heating device is not higher than a minimum liquid level, activating the water pump of the water purifier to deliver water from the water tank to the heating device to replenish the heating device; activating the heating device to heat the liquid contained within it, wherein the liquid is water or a mixture of water and a specified substance; and stopping the heating device when the temperature of the liquid reaches a target temperature corresponding to the heating command.

[0006] In some embodiments, activating the water pump of the water purifier to deliver water from the purified water tank to the heating device to replenish the heating device includes at least one of the following: activating the water pump and starting a timer; stopping the water pump when the timer reaches a target replenishment duration to stop delivering water from the purified water tank to the heating device; or activating the water pump and stopping it when the liquid level in the heating device reaches a target level to stop delivering water from the purified water tank to the heating device. This ensures that sufficient water is replenished to the heating device each time or that the heating device is maintained at a suitable liquid level.

[0007] In some embodiments, after starting the water pump of the water purifier, the method further includes: stopping the water pump if the heating device is detected to have left the heating position; stopping water production using the filter assembly if the water level in the purified water tank reaches the target water level; and putting the water purifier into a standby state.

[0008] By automatically stopping the water pump when the heating device leaves the heating position, and stopping water production and entering standby mode when the water level in the purified water tank reaches the target level, the user experience is improved.

[0009] In some embodiments, after stopping the water pump if the heating device is detected to have left the heating position, the method further includes: recording the duration of the heating device's absence; determining the liquid level of the heating device if the heating device is detected to have returned to the heating position and the absence duration is not greater than a target absence duration; starting the water pump if the liquid level of the heating device is not higher than the minimum liquid level to supply water from the purified water tank to the heating device; starting the heating device to heat the liquid it contains; and stopping the heating device when the liquid temperature reaches the target temperature corresponding to the heating command.

[0010] This allows the heating device to automatically continue working after the user removes it from the water purifier and puts it back on, improving the water purifier's intelligence and enhancing the user experience.

[0011] In some embodiments, after recording the departure time of the heating device, the method further includes: if it is detected that the heating device has returned to the heating position and the departure time is greater than the target departure time, keeping the heating device in a stopped state.

[0012] By stopping the heating device from automatically heating, users can issue a heating command again as needed, allowing them to choose whether to continue heating, thus improving the user experience.

[0013] In some embodiments, after starting the water pump of the water purifier to deliver water from the water tank to the heating device, the method further includes: if the water tank is detected to be in a removed state, stopping the water production using the filter assembly and stopping the water pump; if the heating device has been started, continuing to heat the liquid contained in the heating device; and stopping the heating device when the temperature of the liquid reaches the target temperature corresponding to the heating command.

[0014] If the water tank is detected to be removed during the process of the filter component replenishing water to the water tank, the filter component stops producing water and the water pump stops working. The heating device continues to start heating to heat the liquid to the target temperature, thereby improving the intelligence level of the water purifier and enhancing the user experience.

[0015] In some embodiments, after using the filtration assembly to produce water and delivering the produced water to the water purification tank, the method further includes: if the water level in the water purification tank reaches the target water level, stopping the use of the filtration assembly to produce water; and putting the water purifier into a standby state.

[0016] By stopping water production using the filtration components when the water level in the water tank reaches the target level, the water tank can always be kept full or have water, reducing the waiting time for users to add water to the heating device and improving the user experience.

[0017] In some embodiments, after starting the water pump of the water purifier to deliver water from the water tank to the heating device, the method further includes: maintaining or reusing the filter assembly to produce water and delivering the produced water to the water tank; and stopping the use of the filter assembly to produce water if the water level in the water tank reaches the target water level.

[0018] By continuing to produce water using the filtration components while the water pump replenishes the heating device, and then delivering the produced water to the clean water tank, the clean water tank is always kept full or has water in it.

[0019] In some embodiments, after determining whether the heating device is in the heating position, the method further includes: if the heating device is in the heating position and the liquid level of the heating device is higher than the minimum liquid level, starting the heating device to heat the liquid contained therein; and stopping the heating device when the temperature of the liquid reaches the target temperature corresponding to the heating command.

[0020] By directly activating the heating device when it is in the heating position and the liquid level is above the minimum level, the liquid in the heating device is automatically and efficiently heated to the target temperature, thus improving the user experience.

[0021] In a second aspect, a water purifier is provided, which is controlled by the control method of the water purifier as described in the first aspect, the water purifier including the filter assembly, the purified water tank, the water pump and the heating device.

[0022] By applying the above technical solution, in response to the power-on command of the water purifier, the filter components of the water purifier are flushed; if the water tank is in the installed state and the water level in the tank has not reached the target level, the filter components are used to produce water, and the produced water is delivered to the water tank; in response to the heating command of the water purifier's heating device, it is determined whether the heating device is in the heating position; if the heating device is in the heating position and the liquid level in the heating device is not higher than the minimum liquid level, the water pump of the water purifier is started to deliver water from the water tank to the heating device to replenish the heating device; the heating device is started to heat the liquid it contains, wherein the liquid is water or a mixture of water and a specified substance; when the temperature of the liquid reaches the target temperature corresponding to the heating command, the heating device stops heating. In this way, while automatically replenishing water to the heating device using the water pump, water can also be automatically replenished to the water tank, ensuring that the water tank is always in a state of having water or being full, shortening the user's waiting time when replenishing water to the heating device, and improving the user experience.

[0038] Various embodiments and features of this application are described herein with reference to the accompanying drawings.

[0039] It should be understood that various modifications can be made to the embodiments described herein. Therefore, the above description should not be considered as limiting, but merely as an example of embodiments.

Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that could obscure the application. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in a variety of substantially any suitable detailed structures.

[0045] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0046] An embodiment of this application discloses a control method for a water purifier. If the water purifier's water tank is in the installation state and the water level in the tank has not reached the target water level, water is produced using a filtration component, and the produced water is delivered to the water purifier. If the heating device is in the heating position and the water level in the heating device is not higher than the minimum water level, the water pump of the water purifier is activated to deliver water from the water tank to the heating device to replenish the heating device. In this way, while the water pump automatically replenishes water to the heating device, it can also automatically replenish water to the water tank, ensuring that the water tank is always in a state of having water or being full. This shortens the waiting time for the user when replenishing water to the heating device and improves the user experience.

[0047] like Figure 1 As shown, it includes the following steps:

[0048] Step S101: In response to the power-on command of the water purifier, the filter assembly of the water purifier is flushed.

[0049] In this embodiment, the water purifier includes a filter assembly, a purified water tank, a water pump, and a heating device. The filter assembly is used to produce water, specifically, to filter raw water into purified water. The purified water tank can hold the water produced by the filter assembly. The water pump is used to deliver the water from the purified water tank to the heating device to replenish it. The heating device is used to heat the liquid it contains. The heating device can be, for example, an electric kettle or a health-preserving kettle. The purified water tank and the heating device are detachably mounted on the water purifier.

[0050] The power-on command can be issued by the user or automatically triggered when power-on conditions are met, such as a timed power-on schedule. In response to the power-on command for the water purifier, the filter components of the water purifier are flushed to ensure that the water quality in the subsequent water purification process meets the target water quality requirements.

[0051] Step S102: If the water purifier's water tank is in the installation state and the water level in the water tank has not reached the target water level, the filter assembly is used to produce water, and the produced water is delivered to the water tank.

[0052] In this embodiment, it is detected whether the water purification tank is in the installation state. If it is in the installation state, it is detected whether the water level in the water purification tank has reached the target water level. If the target water level has not been reached, water is produced using the filtration assembly, and the produced water is delivered to the water purification tank. A first liquid level sensor can be installed in the water purification tank to obtain the water level.

[0053] In some embodiments of this application, if the water purifier tank is detected to be in a removed state, the water purifier is put into a standby state, thereby ensuring the reliability of the water purifier.

[0054] Step S103: In response to a heating command to the heating device of the water purifier, determine whether the heating device is in the heating position.

[0055] In this embodiment, the heating command for the heating device can be issued by the user or automatically triggered when heating conditions are met. Heating conditions, for example, can trigger the heating command when the temperature is below a target temperature. The heating command can include the target temperature, and different heating commands can correspond to different target temperatures. In response to the heating command, it is determined whether the heating device is in the heating position.

[0056] Step S104: If the heating device is in the heating position and the liquid level of the heating device is not higher than the minimum liquid level, start the water pump of the water purifier to deliver water from the water tank to the heating device to replenish the heating device.

[0057] In this embodiment, if the heating device is in the heating position, it is determined whether the liquid level of the heating device is higher than the minimum liquid level. If it is not higher than the minimum liquid level, it indicates that the liquid level of the heating device is too low. To prevent the heating device from drying out, the water pump of the water purifier is started to deliver water from the purified water tank to the heating device to replenish it. The heating device may be equipped with a second liquid level sensor to determine the liquid level of the heating device.

[0058] Step S105: Activate the heating device to heat the liquid contained within it, wherein the liquid is water or a mixture of water and a specified substance.

[0059] In this embodiment, the liquid contained in the heating device is water or a mixture of water and a specified substance. For example, if the heating device is an electric kettle, the liquid can be water. If the heating device is a health-preserving kettle, the liquid can be a mixture of water and a specified substance, such as tea leaves or food ingredients. While the water pump is replenishing water, the heating device can be activated to heat the liquid it contains.

[0060] Step S106: When the temperature of the liquid reaches the target temperature corresponding to the heating command, the heating device is stopped.

[0061] In this embodiment, when the liquid temperature reaches the target temperature corresponding to the heating command, it indicates that the heating of the liquid has been completed, and the heating device is stopped. Specifically, this can be achieved by disconnecting the power to the heating device. For example, if the target temperature corresponding to the heating command is 80°C, the heating device will stop when the liquid temperature reaches 80°C.

[0062] In some embodiments of this application, after the heating device stops heating, it enters a heat preservation mode to keep the liquid at the target temperature, thereby improving the user experience.

[0063] The control method for a water purifier according to this application embodiment, in response to a power-on command for the water purifier, flushes the filter assembly of the water purifier; if the water tank of the water purifier is in the installation state and the water level in the water tank has not reached the target water level, water is produced using the filter assembly and the produced water is delivered to the water tank; in response to a heating command for the heating device of the water purifier, it determines whether the heating device is in the heating position; if the heating device is in the heating position and the liquid level in the heating device is not higher than the minimum liquid level, the water pump of the water purifier is started to deliver water from the water tank to the heating device to replenish the heating device; the heating device is started to heat the liquid it contains, wherein the liquid is water or a mixture of water and a specified substance; when the temperature of the liquid reaches the target temperature corresponding to the heating command, the heating device stops heating. In this way, while automatically replenishing water to the heating device using the water pump, water can also be automatically replenished to the water tank, ensuring that the water tank is always in a state of having water or being full, shortening the waiting time for the user when replenishing water to the heating device, and improving the user experience.

[0064] In some embodiments of this application, activating the water pump of the water purifier to deliver water from the purified water tank to the heating device to replenish the heating device includes at least one of the following:

[0065] Start the water pump and start timing. When the timer reaches the target water replenishment time, stop the water pump to stop the water in the clean water tank from being delivered to the heating device.

[0066] Start the water pump, and when the liquid level in the heating device reaches the target level, stop the water pump to stop supplying water from the clean water tank to the heating device.

[0067] In this embodiment, a timer can be started after the water pump is started. If the timer reaches the target water replenishment duration, the water pump is stopped, thus ensuring that sufficient water is replenished to the heating device each time. Alternatively, the liquid level of the heating device can be monitored after the water pump is started. If the liquid level reaches the target level, the water pump is stopped, thus maintaining the heating device at a suitable liquid level.

[0068] In some embodiments of this application, after starting the water pump of the water purifier, such as Figure 2 As shown, it also includes the following steps:

[0069] Step S107: If the heating device is detected to have left the heating position, the water pump is stopped.

[0070] In this embodiment, in some cases, the user will remove the heating device to pour out the heated liquid. Therefore, if the heating device is detected to be away from the heating position, it means that the user has removed the heating device. At this time, the water pump is stopped to stop replenishing water to the heating device.

[0071] Step S108: If the water level in the purified water tank reaches the target water level, stop using the filter assembly to produce water.

[0072] In this embodiment, the water level in the water purification tank is monitored. If the water level in the water purification tank has reached the target level, it means that there is enough water in the water purification tank, and the water production using the filtration component is stopped.

[0073] Step S109: Put the water purifier into standby mode.

[0074] In this embodiment, since there is no need to produce water or add water to the heating device at this time, the water purifier enters standby mode.

[0075] By automatically stopping the water pump when the heating device leaves the heating position, and stopping water production and entering standby mode when the water level in the purified water tank reaches the target level, the user experience is improved.

[0076] Understandably, if the water level in the purified water tank does not reach the target level, the filtration system will continue to produce water. Alternatively, if the water level in the purified water tank drops below the target level, the filtration system will resume producing water.

[0077] In some embodiments of this application, after the water pump is stopped if the heating device is detected to have left the heating position, such as... Figure 3 As shown, it also includes the following steps:

[0078] Step S110: Record the duration of the heating device's absence.

[0079] Step S111: If the heating device is detected to have returned to the heating position and the departure time is not greater than the target departure time, the liquid level of the heating device is determined.

[0080] The target departure time is preset (e.g., 5 minutes). If the heating device is detected to return to the heating position, it is determined whether the departure time is not greater than the target departure time. If it is not greater than the target departure time, the liquid level of the heating device is determined, and subsequent water replenishment can be determined based on the liquid level.

[0081] In some embodiments of this application, in order to ensure that the corresponding departure time is accurately determined after the heating device is removed next time, the departure time is reset to zero after the heating device is detected to have returned to the heating position.

[0082] Step S112: If the liquid level of the heating device is not higher than the minimum liquid level, start the water pump to transport water from the clean water tank to the heating device to replenish the heating device.

[0083] In this embodiment, if the liquid level of the heating device is not higher than the minimum liquid level, it means that water needs to be added to the heating device. The water pump is started to transport the water in the clean water tank to the heating device to add water to the heating device.

[0084] Step S113: Start the heating device to heat the liquid it contains.

[0085] While the water pump is replenishing water, the heating device is activated to heat the liquid it contains.

[0086] Step S114: When the temperature of the liquid reaches the target temperature corresponding to the heating command, stop the heating device.

[0087] In this embodiment, when the temperature of the liquid reaches the target temperature corresponding to the heating command, it indicates that the heating of the liquid has been completed, and the heating device is stopped.

[0088] By using the above method, the heating device will automatically continue to work after the user removes it from the water purifier and puts it back on, which improves the intelligence level of the water purifier and enhances the user experience.

[0089] In some embodiments of this application, after recording the duration of absence of the heating device, such as Figure 4 As shown, it also includes the following steps:

[0090] Step S115: If it is detected that the heating device has returned to the heating position and the departure time is greater than the target departure time, the heating device is kept in a stopped state.

[0091] In this embodiment, if it is detected that the heating device has returned to the heating position and the time away is longer than the target time away, the heating device is kept in a stopped state and will no longer automatically start heating. Subsequently, the user can issue a heating command again as needed, so that the user can choose whether to continue heating the device as needed, thereby improving the user experience.

[0092] In some embodiments of this application, after the water pump of the water purifier is started and the water in the purified water tank is delivered to the heating device, such as... Figure 5 As shown, it also includes the following steps:

[0093] Step S116: If the water tank is detected to be in the removed state, stop using the filter assembly to produce water and stop the water pump.

[0094] In this embodiment, in some situations, the user may need to remove the water tank, for example, to clean it. If the water tank is detected to be removed, the water purifier will stop producing water using the filter assembly and stop the water pump because it can no longer store water.

[0095] Understandably, if the filter assembly stops producing water after the water tank is detected to be in the removed state, then the filter assembly should remain stopped producing water. Similarly, if the water pump stops after the water tank is detected to be in the removed state, then the water pump should remain stopped.

[0096] Step S117: If the heating device has been activated, continue to heat the liquid contained in the heating device.

[0097] Once it is confirmed that the water tank has been removed, determine whether the heating device has been activated. If the heating device has been activated, continue to heat the liquid contained within it.

[0098] Step S118: When the temperature of the liquid reaches the target temperature corresponding to the heating command, the heating device is stopped.

[0099] In this embodiment, when the temperature of the liquid reaches the target temperature corresponding to the heating command, it indicates that the heating of the liquid has been completed, and the heating device is stopped.

[0100] If the water tank is detected to be removed during the process of the filter component replenishing water to the water tank, the filter component stops producing water and the water pump stops working. The heating device continues to start heating to heat the liquid to the target temperature, thereby improving the intelligence level of the water purifier and enhancing the user experience.

[0101] In some embodiments of this application, after water is produced using the filtration assembly and the produced water is delivered to the purified water tank, such as... Figure 6 As shown, it also includes the following steps:

[0102] Step S119: If the water level in the purified water tank reaches the target water level, stop using the filter assembly to produce water.

[0103] In this embodiment, if the water level in the water tank reaches the target water level, the water production using the filtration component is stopped to prevent water from overflowing from the water tank.

[0104] Step S120: Put the water purifier into standby mode.

[0105] In this embodiment, since water production is not required at this time, the water purifier enters standby mode.

[0106] By stopping water production using the filtration components when the water level in the water tank reaches the target level, the water tank can always be kept full or have water, reducing the waiting time for users to add water to the heating device and improving the user experience.

[0107] In some embodiments of this application, after the water pump of the water purifier is started and the water in the purified water tank is delivered to the heating device, such as... Figure 7 As shown, it also includes the following steps:

[0108] Step S121: Maintain or reuse the filter assembly for water production, and deliver the produced water to the purified water tank.

[0109] In this embodiment, after the water purifier's pump is started and water from the purified water tank is delivered to the heating device, the water level in the purified water tank will drop as the pump operates. Therefore, to maintain sufficient water in the purified water tank, if the filtration assembly is still being used for water production, then water production using the filtration assembly will continue. If the water level in the purified water tank has reached the target level and water production using the filtration assembly has stopped, then water production using the filtration assembly will resume.

[0110] Step S122: If the water level in the purified water tank reaches the target water level, stop using the filter assembly to produce water.

[0111] In this embodiment, if the water level in the water tank reaches the target water level, the water production using the filtration component is stopped to prevent water from overflowing from the water tank.

[0112] By continuing to produce water using the filtration components while the water pump replenishes the heating device, and then delivering the produced water to the clean water tank, the clean water tank is always kept full or has water in it.

[0113] In some embodiments of this application, after determining whether the heating device is in the heating position, such as Figure 8 As shown, it also includes the following steps:

[0114] Step S123: If the heating device is in the heating position and the liquid level of the heating device is higher than the minimum liquid level, start the heating device to heat the liquid contained in it.

[0115] In this embodiment, if the heating device is in the heating position and the liquid level of the heating device is higher than the minimum liquid level, it means that there is enough liquid in the heating device, and the heating device can be directly started to heat the liquid contained therein.

[0116] Step S124: When the temperature of the liquid reaches the target temperature corresponding to the heating command, the heating device is stopped.

[0117] In this embodiment, when the temperature of the liquid reaches the target temperature corresponding to the heating command, it indicates that the heating of the liquid has been completed, and the heating device is stopped.

[0118] By directly activating the heating device when it is in the heating position and the liquid level is above the minimum level, the liquid in the heating device is automatically and efficiently heated to the target temperature, thus improving the user experience.

[0119] This application also proposes a water purifier, which is controlled using the control method for water purifiers as described in the embodiments of this application. Figure 9 As shown, it includes a filter assembly 10, a clean water tank 20, a water pump 40, and a heating device 50.

[0120] In this embodiment, the filter assembly 10 is used to produce water, specifically, to filter raw water into purified water; the purified water tank 20 is connected to the outlet of the filter assembly 10 and can hold the water produced by the filter assembly 10; the water pump 40 has its inlet connected to the purified water tank 20 and its outlet connected to the heating device 50, and is used to transport the water in the purified water tank 20 to the heating device 50 to replenish the heating device 50; the heating device 50 is used to heat the liquid contained within it, wherein the liquid is water or a mixture of water and a specified substance.

[0121] In some embodiments of this application, the water purifier also includes a controller (not shown in the figure), connected to the filter assembly 10, the water pump 40 and the heating device 50, and configured to perform the control method of the water purifier as described in the various embodiments of this application.

[0122] The water purifier of this embodiment can automatically replenish water to the heating device 50 while using the water pump 40, so that the water tank 20 is always in a state of having water or being full, which shortens the waiting time for users to replenish water to the heating device 50 and improves the user experience.

[0123] In some embodiments of this application, such as Figure 9 As shown, the water purifier also includes:

[0124] The first liquid level sensor 30 is connected to the controller and is used to detect the water level in the water tank 20;

[0125] The second liquid level sensor 60 is connected to the controller and is used to detect the liquid level of the heating device 50.

[0126] For other embodiments of a water purifier according to this application, please refer to the relevant embodiments in the control method of a water purifier according to this application.

[0127] To further illustrate the technical concept of this application, the technical solution will now be explained in conjunction with specific application scenarios.

[0128] This application provides a control method for a water purifier. The water purifier includes a filter assembly, a purified water tank, a water pump, and a heating device. The filter assembly is used to produce water, specifically, to filter raw water into purified water. The purified water tank can hold the water produced by the filter assembly. The water pump is used to deliver the water from the purified water tank to the heating device to replenish it. The heating device is used to heat the liquid it contains. The heating device can be, for example, an electric kettle or a health-preserving kettle. The purified water tank and the heating device are detachably mounted on the water purifier.

[0129] In some embodiments, such as Figure 10 As shown, the control method of the water purifier includes the following steps:

[0130] Step S201: Power on the device.

[0131] Step S202: Rinse the filter assembly.

[0132] Step S203: Is the water tank in the installation state? If yes, proceed to step S204; otherwise, proceed to step S206.

[0133] Step S204: Has the water level in the purified water tank reached the target water level? If yes, proceed to step S206; otherwise, proceed to step S205.

[0134] Step S205: Use the filtration assembly to produce water and then transport the produced water to the water purification tank.

[0135] Step S206, standby.

[0136] By applying the above technical solutions, it can be ensured that the water tank is always filled with water or full, which shortens the waiting time for users to add water to the heating device and improves the user experience.

[0137] In some embodiments, such as Figure 11 As shown, the control method for the water purifier also includes the following steps:

[0138] Step S301: In standby mode, a heating command is received.

[0139] In this embodiment, the water purifier can be put into standby mode through step S206.

[0140] Step S302: Is the heating device in the heating position? If yes, proceed to step S303; otherwise, proceed to step S306.

[0141] Step S303: Is the liquid level of the heating device higher than the minimum liquid level? If yes, proceed to step S304; otherwise, proceed to step S305.

[0142] Step S304: Start the heating device to heat the liquid it contains to the target temperature.

[0143] Step S305: Start the water pump to deliver water from the purified water tank to the heating device. The water pump operates for a duration of T, causing the liquid level in the heating device to reach the target level. Simultaneously, the water pump heats the liquid within the heating device to the target temperature, and the filtration assembly produces water to replenish the purified water tank until the target water level is reached.

[0144] In this embodiment, T represents the target water replenishment duration.

[0145] Step S306, Stop.

[0146] By applying the above technical solutions, when the user activates the heating function of the water purifier in standby mode, the water pump replenishes water to the heating device while the heating device starts heating. Simultaneously, upon detecting a drop in the water level in the purified water tank, the filtration system activates water production to replenish the tank, ensuring the tank is always filled or full. This shortens the waiting time for users to dispense water using the heating device, improves the user experience, and enhances the product's intelligence level.

[0147] In some embodiments of this application, such as Figure 12 As shown, the control method for the water purifier also includes the following steps:

[0148] Step S401: In standby mode, a heating command is received.

[0149] In this embodiment, the water purifier can be put into standby mode through step S206.

[0150] Step S402: Is the heating device in the heating position? If yes, proceed to step S403; otherwise, proceed to step S408.

[0151] Step S403: Is the liquid level of the heating device higher than the minimum liquid level? If yes, proceed to step S404; otherwise, proceed to step S405.

[0152] Step S404: Start the heating device to heat the liquid it contains to the target temperature.

[0153] Step S405: Start the water pump to deliver water from the purified water tank to the heating device. While the water pump is working, the heating device heats the liquid it contains and uses the filtration components to produce water, replenishing the purified water tank.

[0154] Step S406: The water pump operates for a duration of t, and t < T, and it is detected that the clean water tank has been removed.

[0155] Step S407: Stop using the filter assembly to produce water, stop the water pump, and start the heating device to heat the liquid it contains to the target temperature.

[0156] Step S408, Stop.

[0157] By applying the above technical solutions, if the water tank is detected to be removed during the process of the filter component replenishing water to the water tank, the filter component will stop producing water and the water pump will stop working. The heating device will continue to start heating to heat the liquid to the target temperature, thereby improving the intelligence level of the water purifier and enhancing the user experience.

[0158] In some embodiments of this application, such as Figure 13 As shown, the control method for the water purifier also includes the following steps:

[0159] Step S501: The water pump replenishes water to the heating device, and the heating device is started to heat the water.

[0160] Step S502: It is detected that the heating device leaves the heating position during the water replenishment or heating process.

[0161] Step S503: Stop the water pump and simultaneously check whether the purified water tank has reached the target water level. If the purified water tank has not reached the target water level, continue to produce water using the filter components, replenish the purified water tank to the target water level, and then enter standby mode; if the purified water tank has reached the target water level, directly enter standby mode.

[0162] Step S504: In standby mode, it is detected that the heating device has returned to the heating position.

[0163] Step S505: Check if the time away from the heating position is greater than 5 minutes. If yes, proceed to step S509; otherwise, proceed to step S506.

[0164] Step S506: Is the liquid level of the heating device higher than the minimum liquid level? If yes, proceed to step S507; otherwise, proceed to step S508.

[0165] Step S507: Start the heating device to heat the liquid it contains to the target temperature.

[0166] Step S508: Start the water pump to deliver water from the purified water tank to the heating device. The water pump operates for a duration of T, causing the liquid level in the heating device to reach the target level. Simultaneously, the water pump heats the liquid within the heating device to the target temperature, and the filtration components produce water to replenish the purified water tank until the target water level is reached.

[0167] Step S509, Stop.

[0168] By applying the above technical solutions, the water pump stops when the heating device is removed from the heating position, and stops water production and enters standby mode when the water level in the purified water tank reaches the target level. This achieves automatic stopping of the water pump and water production. After the user removes the heating device from the water purifier and puts it back on, the heating device automatically resumes operation, improving the intelligence level of the water purifier and enhancing the user experience.
