In some embodiments, the water purification system further comprises a warm water pipeline 400, the warm water pipeline 400 is connected with the outlet of the second heat exchange channel and the inlet of the thermal regeneration pipeline 200, the warm water pipeline 400 is connected with a warm water intake 401 and a disinfection drainage pipeline 700, the control valve group further has a third state for conducting the heating unit 6 and the warm water pipeline 400, and the control valve group is switched to the third state based on the water purification system being in a disinfection sterilization mode, so that the boiling water of the heating unit 6 flows into the warm water pipeline 400 for high-temperature sterilization and disinfection and is discharged through the disinfection drainage pipeline 700.

When the water purification system is in the disinfection and sterilization mode, the control valve group is switched to a third state to conduct the heating unit 6 and the warm water pipeline 400, so that the boiling water of the heating unit 6 flows into the warm water pipeline 400 to realize high-temperature disinfection and sterilization of the warm water pipeline 400, and finally is discharged through the disinfection and drainage pipeline 700, and the drinking water health of a user is ensured.

Further, a sterilizing drain valve 701 is provided on the sterilizing drain line 700, and the sterilizing drain valve 701 is opened only when the water purification system is in a sterilizing mode to drain sterilized boiling water in the warm water line 400.

It should be noted that, since the warm water pipeline 400 is connected to the outlet of the second heat exchange channel and the inlet of the thermal regeneration pipeline 200, when the pre-filter element 1 needs to be thermally washed and regenerated, the warm water intake 401 is closed, the control valve group is switched to the first state to conduct the water storage unit 3 and the first heat exchange channel, so that the boiling water of the heating unit 6 flows into the second heat exchange channel and exchanges heat with the normal temperature water from the water storage unit 3 in the first heat exchange channel to form hot water with a preset value, and the hot water flows through the warm water pipeline 400, the thermal regeneration pipeline 200 and the first water outlet 112 to flow into the pre-filter element 1 for thermally washing.

It can be understood that when the user needs to take warm water, the regeneration valve 201 is closed, the control valve group is switched to the first state to conduct the water storage unit 3 and the first heat exchange channel, so that the boiling water of the heating unit 6 flows into the second heat exchange channel and exchanges heat with the normal temperature water from the water storage unit 3 in the first heat exchange channel to form hot water with a preset value, and the hot water flows through the warm water pipeline 400 to the warm water intake 401 for the user to take.

That is, when the control valve group is switched to the first state, the control valve group can be used for taking warm water, and also can be used for carrying out hot washing regeneration on the pre-filter element 1, and the two states can be mutually independent operation or can be simultaneously operated, namely, when the pre-filter element 1 is subjected to hot washing regeneration, the warm water intake 401 can be opened to take warm water.

In some embodiments, the control valve set includes a first solenoid valve 101, a second solenoid valve 102, and a third solenoid valve 103, wherein an inlet of the first solenoid valve 101 is connected to the water storage unit 3, an outlet of the first solenoid valve 101 is connected to the first heat exchange channel, an inlet of the second solenoid valve 102 is connected to the water storage unit 3, an outlet of the second solenoid valve 102 is connected to the warm water line 400, an inlet of the third solenoid valve 103 is connected to the heating unit 6, an outlet of the third solenoid valve 103 is connected to an inlet of the second solenoid valve 102, the first solenoid valve 101 is opened based on the control valve set being in a first state, the second solenoid valve 102 is opened based on the control valve set being in a second state, both the second solenoid valve 102 and the third solenoid valve 103 are opened based on the control valve set being in a third state, so that the boiling water of the heating unit 6 flows through the second solenoid valve 102 and the third solenoid valve 103 into the warm water line 400 and is discharged through the disinfection drain line 700.

When the control valve group is in a first state, the first electromagnetic valve 101 is opened, normal-temperature water of the water storage unit 3 enters the first heat exchange channel through the first electromagnetic valve 101, meanwhile boiling water of the heating unit 6 flows into the second heat exchange channel and exchanges heat with normal-temperature water in the first heat exchange channel to form hot water with a preset value so as to thermally flush the front filter element 1, when the control valve group is in a second state, the second electromagnetic valve 102 is opened, the hot water of the water storage unit 3 flows through the second electromagnetic valve 102, the warm water pipeline 400 and the thermal regeneration pipeline 200 to enter the front filter element 1 to flush and cool the front filter element, and when the control valve group is in a third state, the second electromagnetic valve 102 and the third electromagnetic valve 103 are opened so that the boiling water of the heating unit 6 flows through the second electromagnetic valve 102 and the third electromagnetic valve 103 to flow into the warm water pipeline 400 to sterilize and disinfect the front filter element 1 at a high temperature and then is discharged through the disinfection drainage pipeline 700.

Of course, in other embodiments, the control valve set may be configured as a multi-channel valve, where the multi-channel valve has a first channel, a second channel and a third channel, the first channel is connected to the first heat exchange channel and the water storage unit 3, the second channel is connected to the water storage unit 3 and the warm water pipe 400, the third channel is connected to the heating unit 6 and the second channel, when the control valve set is in the first state, the first channel is turned on, when the control valve set is in the second state, the second channel is turned on, and when the control valve set is in the third state, both the second channel and the third channel are turned on.

Because the temperature of the normal temperature water of the water storage unit 3 is constant (consistent with the environment), and the temperature of the boiling water of the heating unit 6 is constant, the hot water subjected to heat exchange by the heat exchange unit 5 is generally at a specific temperature, and factors such as environmental temperature change are likely to influence the hot water subjected to heat exchange by the heat exchange unit 5 not to be at a preset value.

In some embodiments, the temperature adjusting device comprises a temperature adjusting pipeline 600 and a temperature adjusting valve 601, wherein two ends of the temperature adjusting pipeline 600 are respectively connected with the heating unit 6 and the warm water pipeline 400, the temperature adjusting valve 601 is arranged on the temperature adjusting pipeline 600, and the temperature adjusting valve 601 is used for being opened when detecting that the temperature of hot water in the warm water pipeline 400 is lower than a preset value, so that the boiling water in the heating unit 6 flows through the temperature adjusting pipeline 600 and flows into the warm water pipeline 400.

When the temperature of warm water taken by a user is lower than a preset value or the temperature of hot water for hot flushing the front filter element 1 is lower than a preset value, the temperature regulating valve 601 is opened, so that the boiling water of the heating unit 6 flows into the warm water pipeline 400 through the temperature regulating pipeline 600 to be mixed with the hot water in the warm water pipeline 400, and the temperature of the hot water is raised to reach the preset value.

It can be understood that when the user needs to increase the temperature of the warm water taken by the user, or needs to increase the temperature of the hot water for hot flushing the front filter element 1, that is, the preset value needs to be increased, the temperature adjusting valve 601 is opened to enable the boiling water to enter the warm water pipeline 400 through the temperature adjusting pipeline 600 to be mixed with the hot water after heat exchange, so as to achieve the purpose of increasing the temperature of the hot water.

In this embodiment, the heating water outlet 62 is connected to the boiling water intake 301 through the boiling water pipeline 300, the inlet of the second heat exchange channel is connected to the boiling water intake pipeline, and one end of the temperature adjustment pipeline 600 is connected to the boiling water pipeline 300.

As shown in fig. 3, 7 and 6, a boiling water solenoid valve 302 is provided at the boiling water intake 301 to control the opening or closing of the boiling water intake 301 by the boiling water solenoid valve 302, and correspondingly, a warm water solenoid valve 402 is provided at the warm water intake 401 to control the opening or closing of the warm water intake 401 by the warm water solenoid valve 402, and the boiling water intake 301 and the warm water intake 401 are arranged in parallel on the housing 900 of the water purifier, so that a user can conveniently take boiling water or warm water as required.

Because the sealing of the joint of the water purifying pipeline 100 of the whole machine fails, the long-term water leakage of the whole machine causes the distortion and inaccuracy of the detection data of the flow sensor 105, so that the false judgment is made to start the hot washing regeneration of the front filter element 1, and unnecessary accidents are caused.

In some embodiments, the pipeline inspection device includes a first pressure switch 106, the first pressure switch 106 is disposed on the clean water pipeline 100, and if the pressure of the first pressure switch 106 is lower than a first pressure value and is in a closed state, it is determined that the clean water pipeline 100 leaks.

When the pressure of the first pressure switch 106 is lower than the first pressure value and is in the closed state, it indicates that no water flows through the position where the first pressure switch 106 is located or leakage occurs in front of the first pressure switch 106, so that the water pressure is insufficient, and accordingly, it is determined that water leakage exists in the water purifying pipeline 100.

Specifically, the first pressure switch 106 is a low pressure switch, and is in a closed state when the pressure is lower than 0.15Mpa ± 0.05Mpa, and is in an open state when the pressure of the first pressure switch 106 is 0.25Mpa ± 0.05Mpa during normal water intake of the water purification pipeline 100, so that water flow is facilitated.

The first pressure switch 106 may be provided on the water purifying pipe 100 between the pre-cartridge 1 and the fine cartridge 2 to facilitate detection of whether there is water leakage at the front end of the water purifying pipe 100, but is not limited thereto.

In some embodiments, the pipeline inspection device further includes a second pressure switch 502, where the second pressure switch 502 is disposed on the regeneration drain pipeline 500, and determines that the water purifying pipeline 100 is blocked according to the pressure of the second pressure switch 502 being higher than the second pressure value and being in an open state.

When the pressure of the second pressure switch 502 is higher than the second pressure value and is in the open state, it is indicated that the water purifying pipeline 100 behind the second pressure switch 502 is blocked, so that the pressure at the position where the second pressure switch 502 is located is too high, and the pressure is released, so that water flows through, and the water purifying pipeline 100 is blocked.

Specifically, the second pressure switch 502 is a high-pressure switch, and is opened when the pressure is higher than 0.25mpa±0.05Mpa, so as to release pressure in time when the water purifying pipeline 100 is blocked.

When the pre-filter element 1 is subjected to the thermal washing regeneration, the second pressure switch 502 is turned on to facilitate the hot water to be discharged through the regeneration drain line 500.

In some embodiments, the water purification system further includes a pre-filter disposed at the water inlet end of the water purification pipeline 100 for performing primary physical filtration on raw water.

Considering that the water quality of each region is also quite different due to the difference of the using regions, a large amount of large-particle impurities such as silt and stones are possibly contained in the water, if the water is directly connected into the water purifier without physical filtration, the large amount of silt gushes in to cause the blockage of the whole machine and the filter element thereof, so that the service life of the filter element is rapidly reduced, and the service life of the whole machine is greatly reduced.

In particular, the pre-filter may be, but is not limited to, a screen.

In some embodiments, the water purifier further comprises an internet of things communication module, wherein the internet of things communication module is connected with the water purification system and is used for connecting a cloud end to upload health data of the water purifier to the cloud end.

Through thing networking communication module, the user can carry out effective monitoring from thing networking platform to purifier's running condition, filter core life-span data to can be targeted with the health monitoring data uploading of complete machine to the high in the clouds, make things convenient for the backstage maintainer in time to know purifier service condition, conveniently in time overhaul and maintain. Meanwhile, if the water purifier has the requirement of drinking water charge for public charge drinking water, the water purifier also can be used for taking water for drinking after the online payment function is realized through the function of the Internet of things.

Although purified pure water is stored in the water storage unit 3, if the storage time is too long, the water quality of the purified water also changes, for example, precipitation occurs, and therefore, in some embodiments, the water purification system further comprises a post-filter element 4, and the post-filter element 4 is arranged between the water storage unit 3 and the heat exchange unit 5, so that the purified water flowing out of the water storage unit 3 can be filtered again, and the water quality is improved.

In order to prevent the water in the water storage unit 3 or the boiled water in the heating unit 6 from flowing back to the second filter unit 12 of the pre-cartridge 1, a check valve may be provided in the purified water pipe 100 between the second water outlet 122 and the water storage unit 3, and the check valve may only allow the purified water in the second water outlet 122 to flow to the water storage unit 3 and prevent the water from flowing back to the second water outlet 122.
