Description

Technical Field

[0001] This invention relates to the field of water purification technology, and in particular to a water dispensing method for an integrated water purifier and a water purifier. Background Technology

[0002] The water purifier and heater combo is a new type of water purifier that integrates water purification and heating functions. Users can select the water temperature according to their needs. Using the water purifier and heater combo eliminates the need to fill the water with purified water and then boil it, allowing users to enjoy pure hot water instantly, which is safer, healthier, and more convenient.

[0003] The working process of a water purifier and heater is as follows: first, it purifies water; then, it heats the purified water; finally, once the purified water in the heating tank has reached a certain temperature, it is ready for use. However, during the first use after installation, the pipes downstream of the heating tank are filled with gas. Heating the purified water in the tank produces a large amount of steam. The accumulation of steam in the pipes increases pressure. If the user opens the water inlet, the accumulated hot steam will spray out along with the hot water, potentially scalding the user.

[0004] Therefore, how to devise a water outlet method that avoids hot steam spraying when users take water for the first time after the installation of the integrated water purifier and heating unit is an urgent technical problem that needs to be solved. Summary of the Invention

[0005] The first objective of this invention is to provide a water dispensing method for a combined heat and water purifier, so that users will not come into contact with hot air when taking water for the first time after the combined heat and water purifier is installed, thus ensuring high safety.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A method for discharging water from an integrated water purifier and heat pump includes the following steps:

[0008] S1. Determine if the integrated heat and water purifier is in its pre-first-water-intake state;

[0009] S2. If the integrated heat and water purifier is in the state before the first water intake, perform the first water intake and obtain the water level of pure water in the hot tank;

[0010] S3. Determine whether the water level of the pure water in the hot tank has reached the target water level;

[0011] S4. If the pure water level reaches the target level, open the outlet located downstream of the hot tank to release air in advance.

[0012] S5. After the water outlet has been open for a first target duration, the water outlet is closed.

[0013] Preferably, step S1, determining whether the integrated heat and water purifier is in its pre-first-water-intake state, specifically includes the following steps:

[0014] Determine whether the hot tank contains water;

[0015] Determine whether the high-pressure switch of the pressure tank located upstream of the hot tank is in the closed state;

[0016] If there is no water in the hot tank and the high-pressure switch is in the closed state, it can be determined that it is in the state before the first water intake.

[0017] Preferably, step S1, determining whether the integrated heat and water purifier is in its pre-first-water-intake state, specifically includes the following steps:

[0018] Determine whether the electronic control components installed on the raw water circuit are being triggered for the first time;

[0019] If the electronic control component is triggered for the first time, it can be determined to be in the state before the first water ingress.

[0020] Preferably, the electronic control components include at least one of an inlet solenoid valve, a booster pump, and an inlet TDS probe.

[0021] Preferably, step S2, the initial water intake includes the following steps;

[0022] Open the inlet solenoid valve located on the raw water line;

[0023] When the opening time of the inlet solenoid valve reaches the second target duration, the booster pump is turned on.

[0024] Preferably, step S5, after closing the water outlet, further includes the following steps:

[0025] Determine whether the high-pressure switch of the pressure tank located upstream of the hot tank is in the closed state;

[0026] If the high-voltage switch is in the closed state, the booster pump is turned off;

[0027] After the booster pump shut-off time reaches the third target duration, the inlet solenoid valve is closed.

[0028] Preferably, after step S5, the water outlet method of the integrated heat purifier further includes the following steps:

[0029] Determine whether the standby time of the integrated water purifier and heat pump has reached the fourth target time since the user last took water;

[0030] If the standby time of the integrated heat and purifier reaches the fourth target time, the reflux switch valve is opened, so that the pure water temporarily stored in the pressure tank first flows to the post-filter located downstream of the pressure tank, and then flows back to the reverse osmosis filter located upstream of the pressure tank to clean the reverse osmosis filter.

[0031] The second objective of this invention is to provide a thermal purifier that is highly safe to use.

[0032] To achieve this objective, the present invention adopts the following technical solution:

[0033] A combined heat and water purifier machine, using the above-mentioned water dispensing method for the first water dispensing.

[0034] Preferably, the integrated heat and water purification machine includes a reverse osmosis filter element, a pressure tank, a high-pressure switch, a heating tank, and a water level probe. The reverse osmosis filter element has a first water inlet and a second water inlet, and the heating tank has a third water inlet and a fourth water inlet. The first water inlet is used to connect to the raw water pipeline, and the second water inlet and the third water inlet are connected to each other through a pure water pipeline. The fourth water inlet is used to connect to the water supply pipeline. The pressure tank is connected to the pure water pipeline through a connecting pipeline. The high-pressure switch is located upstream of the connection point between the connecting pipeline and the pure water pipeline. The water level probe is located inside the heating tank. The water supply pipeline is equipped with a water outlet valve for controlling its opening and closing.

[0035] Preferably, the water supply pipeline includes a main pipeline, a hot water branch pipeline, and a warm water branch pipeline connected in a Y-shape. The end of the main pipeline is connected to the fourth water outlet. The water outlet switch valve includes a hot water outlet solenoid valve provided on the hot water branch pipeline and a warm water outlet solenoid valve provided on the warm water branch pipeline. The end of the hot water branch pipeline forms a hot water outlet, and the end of the warm water branch pipeline forms a warm water outlet.

[0036] Preferably, the hot water branch pipe and the warm water branch pipe are connected by a switching pipe, which is equipped with a first switching valve; the hot water branch pipe is equipped with a second switching valve, which is located upstream of the connection point between the switching pipe and the hot water branch pipe. When the first switching valve is open and the second switching valve is closed, the hot water outlet is used as the warm water outlet; or, the warm water branch pipe is equipped with a third switching valve, which is located upstream of the connection point between the switching pipe and the warm water branch pipe. When the first switching valve is open and the third switching valve is closed, the warm water outlet is used as the hot water outlet.

[0037] The beneficial effects of this invention are:

[0038] The water dispensing method for the integrated water purifier and heater provided by this invention includes the following steps: S1, determining whether the integrated water purifier and heater is in the pre-first water intake state; S2, if the integrated water purifier and heater is in the pre-first water intake state, performing the first water intake and obtaining the pure water level in the heating tank; S3, determining whether the pure water level in the heating tank has reached the target water level; S4, if the pure water level has reached the target water level, opening the water outlet located downstream of the heating tank to pre-vent air; S5, after the water outlet has been open for a first target time, closing the water outlet. This water dispensing method for the integrated water purifier and heater, during the first water intake process after installation and before the user's first water intake, pre-vents air by opening the water outlet, causing the water in the heating tank to flow into the downstream pipeline, thereby pre-venting the gas in the pipeline and preventing hot air from spraying out during the user's first water intake, thus improving the user's water intake safety.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0047] This invention discloses an integrated water purifier and heater, which can purify and heat raw water to produce pure water with a suitable temperature, allowing users to access hot water at any time, providing convenience and improving their quality of life. Figure 1 As shown, the integrated water purifier and heat pump includes a raw water pipeline, a reverse osmosis filter element 1, a pure water pipeline, a heating tank 4, and a water supply pipeline connected in sequence. The reverse osmosis filter element 1 has a first water inlet and a second water inlet, and the heating tank 4 has a third water inlet and a fourth water inlet. One end of the raw water pipeline is the inlet, and the other end of the raw water pipeline is connected to the first water inlet of the reverse osmosis filter element 1. The second water inlet of the reverse osmosis filter element 1 is connected to one end of the pure water pipeline, and the other end of the pure water pipeline is connected to the third water inlet of the heating tank 4. The fourth water inlet of the heating tank 4 is connected to one end of the water supply pipeline, and the other end of the water supply pipeline forms the outlet. Users can connect to water through the open outlet.

[0048] The raw water pipeline is connected to the water source through the inlet. The raw water in the water source can flow into the reverse osmosis filter element 1 through the raw water pipeline and be filtered in the reverse osmosis filter element 1. After being filtered by the reverse osmosis filter element 1, the raw water becomes pure water. The pure water enters the heating tank 4 through the pure water pipeline. The heating tank 4 heats the pure water. The heated pure water flows out through the water pipeline for users to use.

[0049] In some embodiments, the integrated heat and water purifier also includes a pre-filter 6, which is located on the raw water pipeline and upstream of the reverse osmosis filter 1. The pre-filter 6 is used to perform preliminary filtration of the raw water.

[0050] In one embodiment, the pre-filter 6 includes a PP cotton filter element 61, also known as a melt-blown PP filter element. It is a tubular filter element made of non-toxic and odorless polyester fiber particles through heating, melting, spinning, and drawing. The PP cotton filter element 61 is not only widely used in water purification, but also has strong dirt-holding capacity, long service life, and low cost. It also has excellent chemical compatibility and is suitable for filtering strong acids, strong alkalis, and organic solvents.

[0051] In one embodiment, the pre-filter element 6 includes a carbon rod filter element 62, also known as a sintered activated carbon filter element or CTO filter element. The carbon rod filter element is a new type of deep filtration element, made from high-quality activated carbon as raw material, with a low-heat-melting binder forming its structure. It undergoes continuous extrusion molding and low-temperature sintering to achieve a certain strength. The carbon rod filter element 62 possesses the excellent adsorption performance of granular activated carbon and effectively overcomes the carbon powder leakage defects present in all activated carbon filters. It also exhibits the precision filtration characteristics of tubular elements, effectively removing organic matter, particles, rust, residual chlorine, odors, etc., from liquids.

[0052] In one embodiment, such as Figure 1 As shown, the pre-filter 6 includes two PP cotton filter elements 61 and one carbon rod filter element 62, with the carbon rod filter element 62 disposed between the two PP cotton filter elements 61.

[0053] Continue to refer to Figure 1 As shown, an inlet solenoid valve 7 is also installed on the raw water line, which is used to control the opening and closing of the raw water line. A manual inlet valve 8 is also installed at the inlet of the raw water line. The inlet can be opened and closed by manually controlling the manual inlet valve 8. After the user operates the manual inlet valve 8 to the open state, the user can then power on the inlet solenoid valve 7, and the water in the water source can be pumped into the raw water pipeline by the booster pump 10.

[0054] Continue to refer to Figure 1As shown, an inlet TDS probe 9 is also installed in the raw water path. The inlet TDS probe 9 uses the conductivity of dissolved substances in water to measure the total dissolved solids content in the raw water. The working principle of the inlet TDS probe 9 is based on the conductivity of dissolved substances in water. When the inlet TDS probe 9 is inserted into the raw water, the built-in chip detects the conductivity of the water and converts the detected conductivity into a digital display. The level of the number reflects the content of dissolved solids in the water. The higher the number, the higher the conductivity of the water, that is, the more soluble solid impurities it contains. In one embodiment, the inlet TDS probe 9 is located between the pre-filter 6 and the inlet solenoid valve 7.

[0055] The reverse osmosis filter element 1 also includes a wastewater outlet, and the integrated hot osmosis unit also includes a wastewater pipeline. One end of the wastewater pipeline is connected to the wastewater outlet, and the other end is a waste discharge outlet. Optionally, a wastewater solenoid valve 11 is also provided on the wastewater pipeline to control the opening and closing of the wastewater pipeline. Optionally, the wastewater pipeline includes two parallel branches, namely a first wastewater branch and a second wastewater branch. A wastewater solenoid valve 11 is provided on the first wastewater branch, and a switch ball valve 12 and a wastewater proportioner 13 are provided on the second wastewater branch. The wastewater proportioner 13 is used to control the volume ratio of pure water to wastewater to ensure that a certain proportion of wastewater is generated during the pure water process.

[0056] The wastewater pipeline also includes a first wastewater main pipe that is connected to one end of the first wastewater branch and one end of the second wastewater branch, and the first wastewater main pipe is connected to a wastewater outlet. The wastewater pipeline also includes a second wastewater main pipe that is connected to the other end of the first wastewater branch and the other end of the second wastewater branch, and the second wastewater main pipe forms a waste discharge outlet.

[0057] Continue to refer to Figure 1 As shown, the integrated water purifier also includes a pressure tank 2 and a connecting pipe. One end of the connecting pipe is connected to the pure water pipe, and the other end is connected to the inlet of the pressure tank 2. A pressure tank ball valve is also installed at the connection point between the connecting pipe and the pressure tank 2. The pressure tank 2 has a water storage function. The integrated water purifier can produce a large amount of pure water in one water production process. Excess pure water enters the pressure tank 2 for temporary storage, thus enabling multiple water extractions after one water production. This not only ensures that users can drink pure water at any time, but also avoids damage to the booster pump 10 caused by frequent water production, which is beneficial to extending the service life of the integrated water purifier. In addition, the pressure tank 2 also has the functions of balancing water volume and pressure, increasing water output speed, and automatic control.

[0058] A high-pressure switch 3 is also installed on the pure water pipeline, located upstream of the connection point between the connecting pipeline and the pure water pipeline. When the pressure inside the pressure tank 2 reaches the specified value, the high-pressure switch 3 will close to cut off the power supply, preventing the integrated heat and purifier from continuing to work and causing excessive pressure. This helps protect the integrated heat and purifier from damage caused by excessive internal pressure and ensures its safe and effective operation.

[0059] Continue to refer to Figure 1 As shown, the integrated heat and air purification machine also includes a first one-way valve 14, which is located on the pure water pipeline and between the reverse osmosis filter 1 and the high-pressure switch 3. The first one-way valve 14 can prevent the pure water in the pressure tank 2 from flowing back upstream.

[0060] The integrated heat and water purification machine also includes an outlet water TDS probe 15, which is located downstream of the connection point between the connecting pipe and the pure water pipe. The outlet water TDS probe 15 uses the conductivity of dissolved substances in water to measure the total dissolved solids content in the pure water.

[0061] Continue to refer to Figure 1 As shown, the integrated water purifier also includes a post-filter 16, which is installed on the pure water pipeline and located downstream of the outlet TDS probe 15. The post-filter 16 further purifies the pure water flowing from the pressure tank 2 or the pure water flowing from the reverse osmosis filter 1. Optionally, the post-filter 16 may include a carbon filter. The integrated water purifier also includes a flow-through LED light 17, whose main function is to sterilize, disinfect, and purify the pure water.

[0062] In some embodiments, the integrated heat and water purification unit further includes a return pipeline and a return switch valve 18. One end of the return pipeline is connected to the pure water pipeline and located downstream of the pressure tank 2, while the other end is connected to the raw water pipeline and located upstream of the reverse osmosis filter element 1. This allows pure water that has not been used for a long time in the pressure tank 2 to flow back to the reverse osmosis filter element 1 through the return pipeline to clean the reverse osmosis filter element 1. Optionally, the return switch valve 18 is a return solenoid valve. Optionally, a second check valve is also provided on the return pipeline.

[0063] Continue to refer to Figure 1 As shown, the heating tank 4 includes a tank body 41 and a heating element 42 disposed within the tank body 41. The heating element 42 heats the pure water located within the tank body 41. Optionally, the heating element 42 is an electric heating element. A drain pipe is also provided at the bottom of the tank body 41, and a drain solenoid valve 30 is provided on the drain pipe.

[0064] In some embodiments, the hot water tank 4 is further provided with a water level probe 51, which is used to obtain the water level of pure water in the tank 41. In one embodiment, two water level probes 51 are provided, one of which is fixed on the side wall of the tank 41 and located at the upper part of the tank 41, and the other is fixed on the top wall of the tank 41. The water level probe 51 provided on the side wall can determine whether the water level in the tank 41 has reached the high level; the water level probe 51 provided on the top wall can determine whether the tank 41 is full of water.

[0065] In some embodiments, a temperature sensor 19 is also provided inside the heating tank 4. The temperature sensor 19 is used to obtain the temperature of the pure water inside the tank 41. If the temperature sensor 19 detects that the temperature of the pure water has reached the target value, the control mechanism of the integrated heat and water purifier can control the heating element 42 to stop heating. In one embodiment, there are two temperature sensors 19. One temperature sensor 19 is located on the side wall of the tank 41 and in the middle of the tank 41, and the other temperature sensor 19 is located on the side wall of the tank 41 and in the upper part of the tank 41.

[0066] It should be noted that users have a need for hot water, which can be either boiling water or warm water. To meet users' needs to the greatest extent, the water pipes are equipped with multiple outlets, some of which can dispense boiling water and others can dispense warm water.

[0067] Specifically, the water supply pipeline includes a main pipeline, a hot water branch pipeline, and a warm water branch pipeline connected in a Y-shape. The end of the main pipeline is connected to the fourth water inlet of the hot water tank 4. A hot water outlet solenoid valve 20 is provided on the hot water branch pipeline, and a hot water outlet is formed at the end of the hot water branch pipeline. A warm water outlet solenoid valve 21 is provided on the warm water branch pipeline, and a warm water outlet is formed at the end of the warm water branch pipeline.

[0068] Optionally, the warm water branch pipeline can be set to multiple lines as needed. The multiple warm water branch pipelines can be completely parallel to form a parallel pipeline, or they can share a part of the pipeline to form a tree-shaped pipeline. Each warm water branch pipeline is equipped with a warm water outlet solenoid valve 21.

[0069] Optionally, the hot water branch pipeline can be set to multiple lines as needed. The multiple hot water branch pipelines can be completely parallel to form a parallel pipeline, or they can share a part of the pipeline to form a tree-shaped pipeline. Each hot water branch pipeline is equipped with a hot water outlet solenoid valve 20.

[0070] Furthermore, the hot water branch pipe and the warm water branch pipe can also be connected by a switching pipe. A first switching valve 22 is provided on the switching pipe, and a second switching valve 23 is provided on the hot water branch pipe. The second switching valve 23 is located upstream of the connection point between the hot water branch pipe and the switching pipe. The first switching valve 22 and the second switching valve 23 can be solenoid valves or manual valves. By opening the first switching valve 22 on the switching pipe and closing the second switching valve 23, the warm water branch pipe can be connected to part of the hot water branch pipe, so that the hot water outlet can be temporarily used as a warm water outlet.

[0071] Of course, a third switch valve can also be installed on the warm water branch pipe. The third switch valve is located upstream of the connection point between the warm water branch pipe and the switching pipe. The third switch valve can be a solenoid valve or a manual valve. By opening the first switch valve 22 on the switching pipe and closing the third switch valve, the hot water branch pipe can be connected to part of the warm water branch pipe, so that the warm water outlet can be temporarily used as the hot water outlet.

[0072] In some embodiments, warm water can be obtained by cooling boiled water, and so on. Figure 1 As shown, the integrated heat and water purifier also includes a heat exchanger 24. The pure water pipeline includes a first pure water branch pipeline and a second pure water branch pipeline connected in parallel. The first pure water branch pipeline is equipped with a sterilization inlet solenoid valve 28, and the second pure water branch pipeline is equipped with a water replenishment valve 27. A safety valve 29 is also provided at the third water inlet. The heating tank 4 also has a fifth water inlet. A cooling pipeline connects the second water inlet and the warm water branch pipeline. The lower-temperature pure water in the second pure water branch pipeline and the boiling water in the cooling pipeline exchange heat through the heat exchanger 24, thereby lowering the temperature of the pure water in the cooling pipeline, cooling the boiling water to warm water, while raising the temperature of the pure water in the second pure water branch pipeline. This avoids energy waste and helps reduce the energy consumption of the heating element 42.

[0073] Optionally, a manual temperature control valve 25 is also installed at the connection between the cooling pipeline and the warm water branch pipeline. By adjusting the flow rate in the cooling pipeline through the manual temperature control valve 25, the temperature of the obtained warm water can be controlled. A warm water NTC 26 is also installed on the warm water branch pipeline for temperature measurement.

[0074] The integrated heat and air purifier also includes a control mechanism, which can be a centralized or distributed controller. For example, the controller can be a single microcontroller or a combination of multiple distributed microcontrollers. The microcontroller can run a control program to control all the electronic components included in the integrated heat and air purifier to perform their respective functions.

[0075] This invention also discloses a water dispensing method for an integrated heat purifier and water heater, such as... Figure 2 As shown, the water dispensing method of the integrated water purifier and heat pump includes the following steps:

[0076] S1. Determine if the integrated heat and water purifier is in its pre-first-water-intake state;

[0077] S2. If the integrated water purifier and heat pump is in the state before the first water intake, perform the first water intake and obtain the water level of pure water in the heat tank 4;

[0078] S3. Determine whether the water level of pure water in hot tank 4 has reached the target water level;

[0079] S4. If the pure water level reaches the target level, open the outlet located downstream of the hot tank 4 to release air in advance.

[0080] S5. After the outlet has been open for the first target duration, close the outlet.

[0081] The water dispensing method of this integrated water purifier and heat pump involves opening the outlet in advance to release air during the first water intake process after installation, before the user takes water for the first time. This allows the water in the heating tank 4 to flow into the downstream pipeline, thus expelling the air from the pipeline in advance. The pure water flowing out of the heating tank 4 can basically fill the downstream pipeline. Subsequently, when the user takes water for the first time, because the pipeline is full of water, there will be no hot air ejection, avoiding the user being burned by hot air with high pressure and high temperature, and improving the user's water intake safety.

[0082] In some embodiments, step S1, determining whether the integrated heat purifier is in the pre-first-water-intake state, specifically includes the following steps:

[0083] Determine if there is water in hot tank 4;

[0084] Determine whether the high-pressure switch 3 of the pressure tank 2 located upstream of the hot tank 4 is in the closed state;

[0085] If there is no water in the hot tank 4 and the high-pressure switch 3 is in the closed state, it can be determined that it is in the state before the first water intake.

[0086] It should be noted that once the integrated water purifier and heat pump has completed its initial use, the tank 41 of the heating tank will generally remain full of pure water. Only if the tank 41 is damaged, resulting in significant leakage, will the water level in the heating tank 4 drop or even disappear. In the event of accidental damage to the tank 41, the integrated water purifier and heat pump will determine that the heating tank 4 is short of water and will begin the water purification process. At this time, the high-pressure switch 3 will inevitably be in the open position. Therefore, if there is no water in the heating tank 4 and the high-pressure switch 3 is in the closed position, it can be determined that the integrated water purifier and heat pump is in its pre-initial water intake state, meaning that subsequent water intake will be considered the initial water intake.

[0087] In some parallel embodiments, step S1, determining whether the integrated heat purifier is in the state before its first water intake, specifically includes the following steps:

[0088] Determine whether the electronic control components installed on the raw water circuit are being triggered for the first time;

[0089] If the electronic control component is triggered for the first time, it can be determined that it is in the state before the first water ingress.

[0090] Optionally, the electronic control components include at least one of the following: inlet solenoid valve 7, booster pump 10, and inlet TDS probe 9. It should be noted that the initial triggering of one electronic control component can determine whether the state is before the first water intake, or multiple electronic control components can be triggered simultaneously to determine whether the state is before the first water intake. Only when multiple electronic control components are triggered for the first time is the state determined to be before the first water intake. This method reduces the probability of false positives.

[0091] In some embodiments, step S2, which involves the initial water intake, specifically includes the following steps;

[0092] Open the inlet solenoid valve 7 located on the raw water line;

[0093] When the opening time of the inlet solenoid valve 7 reaches the second target duration, the booster pump 10 is turned on.

[0094] By opening the inlet solenoid valve 7 first, and then delaying the start of the booster pump 10, the booster pump 10 can be protected, preventing it from running dry and being damaged. In one embodiment, after the inlet solenoid valve 7 is opened, the booster pump 10 starts after a 200ms delay. Furthermore, after the booster pump 10 starts, the water production icon on the integrated water purifier's display screen switches to a constantly lit state, reminding the user that the integrated water purifier has started producing water. The specific value of the second target duration is not limited here.

[0095] In step S3, a water level probe 51, located on the side wall of tank 41 and at the top of tank 41, is used to determine whether the water level in tank 41 has reached the target water level. The height of the water level probe 51 is the height of the target water level. If the water level probe 51 can detect pure water, it means that the water level in tank 41 has reached the target water level. The specific value of the target water level height is not limited here.

[0096] In step S4, the water outlet can be either a hot water outlet or a warm water outlet. In order to expel air from the water pipe, it is preferable to open all the hot water outlets and all the warm water outlets.

[0097] In step S5, the first target duration is set according to requirements. In one embodiment, the first target duration is 5 minutes.

[0098] Furthermore, in step S5, after closing the water outlet, the following steps are also included:

[0099] Determine whether the high-pressure switch 3 of the pressure tank 2 located upstream of the hot tank 4 is in the closed state;

[0100] If the high-pressure switch 3 is in the closed state, then the booster pump 10 is turned off;

[0101] After the booster pump 10 has been shut off for the third target duration, the inlet solenoid valve 7 is closed.

[0102] In one embodiment, after the booster pump 10 is turned off, the inlet solenoid valve 7 closes after a 200ms delay. Afterward, the water purification icon on the integrated water purifier's display screen turns off, reminding the user that water purification is complete.

[0103] The integrated heat purifier is activated according to the user's needs. In daily life, there are situations where the integrated heat purifier is left idle for a long time without being activated. At this time, a portion of pure water is stored in the pressure tank 2. This portion of pure water may be contaminated due to secondary pollution if it is not used for a long time.

[0104] To address the issue of secondary contamination of the purified water in pressure tank 2 when it is not used for an extended period, in some embodiments, after step S5, the water discharging method of the integrated heat and water purifier further includes the following steps:

[0105] Determine whether the standby time of the integrated water purifier and heat pump has reached the fourth target time since the user last took water;

[0106] If the standby time of the integrated heat and purifier reaches the fourth target time, the reflux switch valve 18 will be opened, so that the pure water temporarily stored in the pressure tank 2 will flow back to the reverse osmosis filter element 1 located upstream of the pressure tank 2, and the reverse osmosis filter element 1 will be cleaned.

[0107] This setup allows the use of unused pure water in pressure tank 2 to clean the reverse osmosis filter element 1, thus making full use of the pure water.

[0108] In one embodiment, the duration of the fourth target is set to 24 hours. Of course, in other embodiments, the duration of the fourth target can be set to other durations as needed.

[0109] Furthermore, the cleaning of reverse osmosis filter element 1 also includes the following steps:

[0110] Open the wastewater solenoid valve 11, and the water that has cleaned the reverse osmosis filter element 1 will be discharged through the wastewater outlet.

[0111] In some embodiments, the pure water temporarily stored in the pressure tank 2 first flows to the post-filter 16 located downstream of the pressure tank 2, and then flows back to the reverse osmosis filter 1.

[0112] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
