Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The disclosed embodiment provides a water purifier 10, as shown in fig. 1, the water purifier 10 includes a water purification system 101, i.e., a hot pipe 102, a reverse path 103, a forward path 104, and a control module (not shown in fig. 1).

Wherein, the input end of the instant heating pipe 102 is connected with the output end of the water purification system 101, that is, the output end of the instant heating pipe 102 is respectively connected with the reverse path 103 and the forward path 104, and the control module is respectively connected with the instant heating pipe 102, the reverse path 103 and the forward path 104.

The water purification system 101 is used to purify raw water and output purified water.

The instant heating pipe 102 is used to heat the purified water output from the water purification system 101 when turned on.

The control module is used for respectively acquiring a target temperature set by a user and a real-time temperature of purified water output by the heat pipe 102, and controlling the purified water output by the heat pipe 102 to be output from the forward passage 104 when a difference value between the target temperature and the real-time temperature is less than or equal to a first preset temperature threshold value; when the difference value between the target temperature and the real-time temperature is greater than the first preset temperature threshold value, the control is that the purified water output by the heat pipe 102 is output from the reverse path 103.

The forward path 104 is connected to the water outlet 1041 of the water purifier 10, and is configured to discharge purified water output by the heat pipe 102 from the water outlet 1041 when a difference between the target temperature and the real-time temperature is less than or equal to a first preset temperature threshold, so as to be convenient for a user to take.

In general, a user may set a target temperature of purified water to be taken by the water purifier 10, and the control module may heat the purified water output from the water purification system 101 according to the target temperature indication, i.e., the heat pipe 102. However, if the user does not use the water purifier 10 for a long time, taking water directly through the water outlet nozzle may cause unheated purified water remaining in the heat pipe 102 to be taken by the user, which may affect the user experience. In order to avoid the above situation, after the control module obtains the target temperature set by the user, the control module may control the instant heat pipe 102 to be turned on and heat the purified water in the instant heat pipe 102, and simultaneously obtain the real-time temperature of the purified water currently output by the instant heat pipe 102, and then determine whether a difference between the target temperature and the real-time temperature is less than or equal to a first preset temperature threshold, that is, determine whether the real-time temperature of the purified water currently output by the instant heat pipe 102 is the same as or close to the target temperature set by the user. If so, that is, the real-time temperature of the purified water output by the heat pipe 102 meets the user requirement, the purified water output by the heat pipe 102 can be directly output from the forward passage 104, that is, directly discharged from the water outlet 1041 of the water purifier 10, and is convenient for a user to take, for example, the user can take through the water receiving tray 20; if not, that is, the real-time temperature of the purified water output by the heat pipe 102 is low, and cannot meet the user requirement, therefore, the purified water output by the heat pipe 102 can be output from the reverse passage 103, and the purified water is prevented from flowing out from the water outlet nozzle 1041 and being taken by the user.

During the process of discharging the purified water output by the heat pipe 102 from the reverse path 103, the control module may determine whether the difference between the target temperature and the real-time temperature of the purified water output by the heat pipe 102 is less than or equal to a first preset temperature threshold. If so, the purified water output by the heat pipe 102 is immediately controlled to be output from the forward path 104, so that the purified water is convenient for a user to take and use, and the purified water is prevented from being wasted inefficiently.

Specifically, the first preset temperature threshold may be set according to an actual usage temperature of the water purifier, for example, the first preset temperature threshold Δ T may be located between 1 ℃ and 5 ℃, that is, Δ T is greater than or equal to 1 ℃ and less than or equal to 5 ℃, and may be adjusted according to specific situations in practical application, which is not limited in this disclosure.

Optionally, the reverse path 103 may be connected to a waste water path of the water purification system 101, that is, when a difference between the target temperature and the real-time temperature is greater than a first preset temperature threshold, purified water whose temperature output by the heat pipe 102 does not meet a user requirement may be directly discharged to a sewer through the waste water path.

By way of example, the instant heating tube 102 may be provided with a temperature sensor 1021 connected to the control module. The temperature sensor 1021 is used for detecting the real-time temperature of the purified water output by the heat pipe 102 and sending the temperature to the control module.

In the technical scheme provided by the embodiment of the present disclosure, the difference between the target temperature set by the user and the real-time temperature of the purified water output by the instant heating pipe 102 can be compared, the control is that the water outlet passage of the instant heating pipe 102 is used, that is, the purified water output by the instant heating pipe 102 with a lower temperature is discharged when the difference is larger, when the difference is smaller, the purified water output by the instant heating pipe 102 is discharged from the water outlet nozzle 1041 so as to be convenient for the user to take, the condition that the temperature of the water taken by the user when the user needs hot water is lower is avoided, the practicability of the water purifier 10 is improved, the popularization and the use of the water purifier 10 are facilitated, and the user experience is better.

In one embodiment, and as shown with reference to FIG. 1, the forward passageway 104 is provided with a solenoid valve 1042 that is connected to the control module.

The control module may control the electromagnetic valve 1042 to open when a difference between a target temperature set by a user and a real-time temperature of purified water output by the heat pipe 102 is less than or equal to a first preset temperature threshold, so that the purified water output by the heat pipe 102 is output from the forward direction path 104.

For example, the solenoid valve 1042 is normally closed to prevent the purified water in the water purifier 10 from flowing out of the water outlet 1041. When the control module determines that the difference between the target temperature set by the user and the real-time temperature of the purified water output by the heat pipe 102 is less than or equal to the first preset temperature threshold, the electromagnetic valve 1042 can be controlled to open, and at this time, the purified water output by the heat pipe 102 can be output from the forward passage 104 to the water outlet nozzle 1041 and taken by the user.

In one embodiment, as shown in fig. 2, the water purification system 101 includes a raw water tank 1011, and the raw water tank 1011 stores raw water that is not purified.

The reverse path 103 is connected to the raw water tank, and is configured to discharge purified water output by the heat pipe 102 into the raw water tank when a difference between the target temperature and the real-time temperature is greater than a first preset temperature threshold.

As an example, the water purifier may be connected to an external water source to obtain purified water by purifying raw water from the external water source, and may further include a raw water tank 1011 to which a user may supplement raw water as needed, and the purifier 10 may obtain purified water by purifying raw water from the raw water tank 1011.

When the difference value between the target temperature set by the user and the real-time temperature of the purified water output by the instantaneous heat pipe 102 is determined to be greater than the first preset temperature threshold value, the purified water output by the instantaneous heat pipe 102 can be discharged into the original water tank 1011 through the reverse passage 103, so that the water discharged into the original water tank 1011 can be purified and used again through the water purification system 101, and waste is avoided.

Alternatively, as shown in fig. 2, a partition plate 1011a may be provided in the raw water tank 1011 for partitioning the raw water to be re-purified, which is discharged into the raw water tank 1011 through the reverse path 103, and the raw water replenished by the user, so as to prevent the raw water to be re-purified from being contaminated by the raw water not to be purified.

Optionally, referring to fig. 2, a water level detection sensor 1011b may be disposed in the raw water tank 1011, and the water level detection sensor 1011b is disposed at a lowest water level allowed by the raw water tank 1011, and is configured to detect whether the water level of the raw water stored in the raw water tank 1011 is low, so as to remind a user of adding water in time when the water level of the raw water stored in the raw water tank 1011 is low.

Alternatively, the raw water tank 1011 may be connected to the water purifier 10 by a detachable means, and when the level of raw water stored in the raw water tank 1011 is low, a user may detach the raw water tank 1011 to replenish raw water and then mount the raw water tank 1011 replenished with raw water to the water purifier 10. Referring to fig. 2, the water purifier 10 may further include a tank detection sensor 106 for detecting whether the raw water tank 1011 is installed, so as to prevent dry burning caused by idle running of the water purifier 10 when the raw water tank 1011 is not installed, thereby prolonging the life of the water purifier 10.

Specifically, the reverse path 103 is provided with a two-way check valve in a region connected to the raw water tank 1011, so that water in the water purification system 101 is prevented from flowing backward when the raw water tank 1011 is detached by a user to replenish raw water. Similarly, a two-way check valve is provided in a region where the raw water tank 1011 is connected to the water purification system 101.

In one embodiment, as shown in FIG. 3, the reverse path 103 is provided with a flush valve 1031 connected to the control module.

The control module is configured to control the flush valve 1031 to open when a difference between a target temperature set by a user and a real-time temperature of purified water output by the heat pipe 102 is greater than a first preset temperature threshold, so that the purified water output by the heat pipe 102 is delivered to the raw water tank 1011 through the reverse path 103.

For example, the flush valve 1031 has a function of passing low pressure preferentially when opened, so that even if the pressure of the flush valve 1031 near the raw water tank 1011 is greater than the pressure near the heat pipe 102, that is, the purified water output by the heat pipe 102 can be delivered to the raw water tank 1011 through the reverse path 103 in the case that the difference between the target temperature and the real-time temperature is greater than the first preset temperature threshold value.

In one embodiment, referring to fig. 3, a one-way valve 1032 is provided between the flush valve 1031 and the hot pipe 102, the one-way valve 1032 being used to prevent water flowing into the reverse path 103 from flowing back to the forward path 104.

In one embodiment, the waste water path of the water purification system 101 may be connected to the reverse path 103, so that the waste water generated by the water purification system 101 is transferred to the raw water tank 1011 through the reverse path 103 for purification and reuse.

Illustratively, as shown in fig. 4, the water purification system 101 includes at least two filter elements 1012, the waste water is discharged through the last filter element, and in order to realize the purification and reuse of the waste water, the waste water discharge outlet 1012a of the last filter element can be connected with the reverse path 103, so that the waste water produced by the filtration of the filter element 1012 can enter the reverse path 103 and then be conveyed to the raw water tank 1011. That is to say, when detecting that filter core 1012 work purifies the raw water, control module also can instruct flush valve 1031 to open, and the waste water of being convenient for is carried, and this check valve 1032 also can avoid the backward flow of waste water to the forward route simultaneously.

Alternatively, as shown in fig. 4, the purified water filtered by the at least two filter elements 1012 can be stored in the purified water tank 1013, and a water pump 1014 is disposed between the purified water tank 1013 and the instant heating pipe 102, and the water pump 1014 is configured to be turned on according to the control of the control module when a user takes water, and pump the purified water stored in the purified water tank 1013 to the instant heating pipe 102 for heating. In practice, the instant heating tube 102 can also be directly connected to the filter element 1012, i.e., the water purifier 10 can be purified in real time when a user takes water.

In one embodiment, the water purifier 10 may further be provided with an interactive interface connected to the control module, and the control module is configured to display a prompt message through the interactive interface when the difference between the target temperature and the real-time temperature is greater than the first preset temperature threshold, where the prompt message is used to indicate the actual working state of the water purifier 10.

For example, since the control module may control the purified water output by the heat pipe 102 to be output from the reverse path 103 to avoid being taken by the user when it is determined that the difference between the target temperature set by the user and the real-time temperature of the purified water output by the heat pipe 102 is greater than the first preset temperature threshold, the user may not take the purified water for a long time after the target temperature is set, and if the waiting time is long, the anxiety of the user may be increased. In order to avoid the above situation, when determining that the difference between the target temperature and the real-time temperature is greater than the first preset temperature threshold, the control module may control the interactive interface to display the prompt information, for example, the interactive interface may display the actual working state of the water purifier 10 through light, text, or sound, or display in real time, that is, the real-time temperature of the purified water output by the heat pipe 102, so that the user can look up the temperature change, reduce the anxiety of the user in waiting, and improve the user experience.

In an embodiment, if the target temperature input by the user is normal temperature, or is close to normal temperature, even if the unheated purified water in the heat pipe 102 flows out from the water outlet nozzle 1041, the use experience of the user is not affected, so the control module may determine whether the target temperature exceeds a preset temperature range after acquiring the target temperature input by the user, where the preset temperature range may be a normal temperature range in a general case, for example, 15 ℃ to 25 ℃, and may be set according to a specific situation in practical application, which is not limited in this disclosure. If the target temperature exceeds the preset temperature range, it indicates that the target temperature may be greatly different from the real-time temperature of the purified water output by the instantaneous heat pipe 102, so that the control module may determine whether the difference between the target temperature and the real-time temperature is less than or equal to a first preset temperature threshold, so as to select the outflow passage of the instantaneous heat pipe 102 according to the determination result. Optionally, the above condition is that the target temperature is greater than the maximum value of the preset temperature range, and in practical application, a condition that the target temperature is less than the minimum value of the preset temperature range may also occur, and at this time, the control module may prompt that the target temperature input is incorrect through the interactive interface, so that the user may input the target temperature again.

In one embodiment, if the user continuously fetches water, that is, the water purifier 10 is in a continuous operation state, it can be presumed that the instant heating pipe 102 can output hot water at a target temperature required by the user in real time, and if the control module still determines in real time a relationship between a difference between the target temperature and a real-time temperature at which the instant heating pipe 102 outputs purified water and a first preset temperature threshold, so as to adjust a water outlet passage according to a determination result, which may cause the control module to perform multiple times of invalid determinations, thereby causing the power consumption of the control module to be large. The control module may thus acquire the continuous operation time of the suction pump 1014 after acquiring the target temperature set by the user, and then determine whether the continuous operation time is less than or equal to a preset time threshold. If the continuous operation time is less than or equal to the preset time threshold, it indicates that the operation time of the water purifier is short, the water purifier is used for the first time or just started, and the difference between the real-time temperature of the purified water output by the heat pipe 102 and the target temperature set by the user is large, at this time, the control module can determine whether the difference between the target temperature and the real-time temperature is less than or equal to the first preset temperature threshold in real time, so as to select the water outlet passage of the heat pipe 102 according to the determination result. If the continuous operation time of the water pump 1014 is longer than the preset time threshold, it indicates that the operation time of the water purifier 10 is longer, that is, the hot water pipe 102 can output the hot water meeting the target temperature required by the user in real time, and there is no situation that the difference between the real-time temperature of the purified water output by the hot water pipe 102 and the target temperature set by the user is larger, at this time, the control module may stop determining whether the difference between the target temperature and the real-time temperature is less than or equal to the first preset temperature threshold, and further stop selecting the water outlet passage of the hot water pipe 102 according to the determination result.

In an embodiment, if the time interval between the last use of the water purifier 10 and the present use of the water purifier 10 by the user is long, that is, the difference between the last use time of the water purifier 10 and the current time is greater than or equal to the preset difference threshold, a situation that the difference between the target temperature set by the user this time and the real-time temperature of purified water output by the instant heat pipe 102 is large may occur, and in order to avoid that the water taken by the user does not meet the requirement, the control module may determine, after obtaining the target temperature, whether the difference between the target temperature and the real-time temperature is less than or equal to the first preset temperature threshold, so as to select the water outlet passage of the instant heat pipe 102 according to the determination result. If the time interval between the last use of the water purifier 10 and the current use of the water purifier 10 by the user is short, that is, the difference between the last use time of the water purifier 10 and the current time is less than the preset difference threshold, that is, the real-time temperature of the purified water output by the heat pipe 102 has not been reduced or is limited, and a situation that the difference between the target temperature set by the user and the real-time temperature of the purified water output by the heat pipe 102 is large is unlikely to occur, at this time, the control module may not adjust the water outlet passage of the heat pipe 102, that is, it is not necessary to determine whether the difference between the target temperature and the real-time temperature is less than or equal to the first preset temperature threshold.

In one embodiment, if the difference between the target temperature and the real-time temperature and the first preset temperature threshold need to be determined after the target temperature set by the user is obtained and then the related data is obtained to determine whether the relationship between the difference between the target temperature and the real-time temperature and the first preset temperature threshold needs to be determined, the processing efficiency of the control module is affected, after the water purifier 10 is out of service, the control module may acquire the out-of-service time of the water purifier 10, then, the real-time temperature of the purified water output by the heat pipe 102 is detected according to the preset period from the time of stopping using, and if the difference value between the real-time temperatures detected in two adjacent preset periods is greater than or equal to a second preset temperature threshold, it indicates that the temperature of the purified water output by the heat pipe 102 is reduced more, and a situation that the difference value between the target temperature set by the user and the real-time temperature of the purified water output by the heat pipe 102 is greater is likely to occur when the purified water is used again, and at this time, the control module may set a label that the purified water is not used continuously. When the control module acquires the target temperature set by the user next time, the difference between the current target temperature and the real-time temperature of the purified water output by the instant heating pipe 102 is rapidly determined to be large according to the label, so that in order to avoid that the water taken by the user does not meet the requirement, the size relation between the difference between the target temperature and the real-time temperature and the first preset temperature threshold value can be determined in real time, and the outlet water passage of the instant heating pipe 102 can be selected according to the determination result. If the tag which is not continuously used is not detected when the control module acquires the target temperature set by the user next time, it indicates that the temperature of the purified water output by the heat pipe 102 is not reduced or is limited at this time, and a situation that the difference between the target temperature set by the user and the real-time temperature of the purified water output by the heat pipe 102 is large is unlikely to occur, and at this time, the control module may not adjust the water outlet passage of the heat pipe 102, that is, it is not required to determine whether the difference between the target temperature and the real-time temperature is less than or equal to the first preset temperature threshold.

The embodiment of the present disclosure provides a water purifier, this water purifier can contrast the target temperature that the user set up and the difference between the real-time temperature of heat pipe output water purification promptly, and will be promptly when this difference is great the lower water purification of temperature of heat pipe 102 output is discharged, when this difference is less will be promptly the water purification of heat pipe 102 output from faucet 1041 discharge be convenient for the user to take, the lower condition of the temperature degree of water of taking when the user needs hot water has been avoided, the practicality of water purifier 10 has been improved, help the using widely of water purifier 10, user experience preferred.
