Description

Technical Field

[0001] The present application relates to the technical field of water purification equipment, and in particular to a pressurized integrated water purification and heating machine. Background Art

[0002] Limited by the boiling point of water at atmospheric pressure of 100°C, in the existing solutions, the built-in hot water tank of the heat and water purifier with heating function can only heat water to 95°C to 100°C at most, and an exhaust port that is always connected to the atmosphere is required. There is often a long water outlet pipe connecting the hot water tank to the water faucet, and there is a lot of residual water in the water outlet pipe. After a long period of standby, the temperature of the water outlet pipe and the residual water in the water outlet pipe will gradually drop to the ambient temperature. When the user takes boiled water again, the residual water in the water outlet pipe will flow into the user's water container together with the boiled water, and the low-temperature water outlet pipe that has been placed for a long time will absorb some of the heat of the hot water. Affected by this, the temperature of the water actually obtained by the user is usually lower than 90°C. In addition, the exhaust port that is always connected to the atmosphere may cause the inside of the hot water tank to be contaminated by bacteria in the air. Utility Model Content

[0003] The present application provides a pressurized integrated heat and water purifier to improve or solve, to a certain extent, the technical problem that the water obtained by users of the existing integrated heat and water purifier is often lower than the selected temperature.

[0004] The technical solution adopted in this application is:

[0005] A pressurized integrated heat and air purifier comprises: a filter unit, the filter unit comprising a filter element and a booster pump connected to a water path upstream of the filter element; a pressure hot water tank, the pressure hot water tank being provided with a sealable booster chamber, the booster chamber being used to store hot water and supply water to a hot water outlet of the integrated heat and air purifier, the hot water continuously increasing the pressure in the booster chamber during the heating process, thereby increasing the heating boiling point; a heating structure, the heating structure being used to heat the clean water filtered and output by the filter element and store it in the booster chamber.

[0006] The booster heat and air purifier in this application also has the following additional technical features:

[0007] A pipeline residual water discharge branch is connected to the fluid path from the boosting chamber to the hot water outlet, a drain valve is provided on the fluid path of the pipeline residual water discharge branch, the pipeline residual water discharge branch is connected to the wastewater discharge port of the heat and water purification machine, and the height of the fluid path from the boosting chamber to the hot water outlet in the vertical direction is not lower than that of the pipeline residual water discharge branch.

[0008] The pressure hot water tank is equipped with an exhaust pressure valve, which has a preset exhaust pressure value. When the air pressure in the boost chamber is less than the exhaust pressure value, the exhaust pressure valve closes the boost chamber. When the air pressure in the boost chamber is greater than or equal to the exhaust pressure value, the exhaust pressure valve is opened to achieve exhaust.

[0009] The pressure hot water tank is equipped with a plurality of safety pressure valves, and the plurality of safety pressure valves correspond to preset safety pressure values ​​which increase in sequence from small to large, and each of the safety pressure values ​​is greater than the exhaust pressure value.

[0010] The pressure hot water tank is equipped with an air intake valve, which has a preset air intake pressure value. When the air pressure in the boost chamber is less than or equal to the air intake pressure value, the air intake valve opens to balance the pressure of the boost chamber and the outside atmosphere.

[0011] The pressure hot water tank is provided with a first water level detection device for detecting a water stop level in the boosting chamber and a second water level detection device for detecting a water replenishment level in the boosting chamber. The water stop level is higher than the water replenishment level. When the water stop level is detected by the first water level detection device, the heat and air purifier stops the filter element from supplying water to the boosting chamber. When the heat and air purifier detects the water replenishment level by the second water level detection device, the filter element starts supplying water to the boosting chamber.

[0012] The pressure hot water tank is provided with a temperature detection device for detecting the water temperature in the boost chamber. When the heat and air conditioning integrated machine detects a first target temperature through the temperature detection device, it controls the heating structure to heat the water in the boost chamber to a second target temperature greater than the first target temperature.

[0013] The heating structure is a heating plate arranged at the bottom of the boosting chamber. The clean water outlet of the filter element is connected to the boosting chamber through a first water replenishment valve, and the boosting chamber is connected to the hot water outlet through a first water pump and a water outlet valve in turn.

[0014] The heating structure is a heating plate arranged at the bottom of the boosting chamber, the clean water outlet of the filter element is connected to the boosting chamber through the second water replenishing valve, the boosting chamber is connected to the water inlet of an instant heating body through the first pressure reducing valve and the second water pump in turn, and the water outlet of the instant heating body is connected to the hot water outlet; the clean water outlet of the filter element is connected to the water inlet of the instant heating body through the second pressure reducing valve and the third water pump in turn, and the second water pump and the third water pump selectively or together pump water to the instant heating body.

[0015] The heating structure is an instant heating body, the clean water outlet of the filter element is connected to the water inlet of the instant heating body through the third pressure reducing valve and the fourth water pump, the boosting chamber is connected to the water inlet of the instant heating body through the fourth pressure reducing valve and the fifth water pump in turn, and the water outlet of the instant heating body is connected to the boosting chamber through the third water replenishment valve and connected to the hot water outlet through the hot water valve.

[0016] Due to the adoption of the above technical solution, the technical effects achieved by this application are:

[0017] 1. The pressurized integrated heat and water purification machine provided in the present application has a pressure hot water tank provided with a closed pressurized chamber, which is used to store hot water and supply water to the hot water outlet of the integrated heat and water purification machine. The heating structure can heat the clean water filtered and output by the filter element and store it in the pressurized chamber. Specifically, in the process of the heating structure heating the water, the pressurized chamber can be made airtight, and the backlog of water vapor continuously generated by the hot water in the pressurized chamber increases the pressure in the pressurized chamber, thereby increasing the boiling point of the water in the pressurized chamber, so that the water temperature in the pressurized chamber can be heated to above 100°C by the heating structure. Therefore, in the process of hot water above 100°C flowing toward the hot water outlet of the integrated heat and water purification machine, even if some heat is lost due to the mixing of the water outlet pipe itself and the residual water inside it, the temperature of the hot water reaching the user's water collection container will be higher than 90°C, thereby effectively increasing the temperature of the water actually obtained by the user and meeting the user's demand for high-temperature boiling water close to 100°C. In addition, in the present solution, when the pressurized chamber is sealed, the contact with the outside air is effectively reduced, thereby reducing the risk of the water stored in the hot water tank being contaminated by bacteria in the air.

[0018] 2. As a preferred embodiment of the present application, a residual water discharge branch is connected to the fluid path from the boost chamber to the hot water outlet. The residual water on the fluid path from the boost chamber to the hot water outlet can be discharged through the residual water discharge branch and the wastewater discharge port by opening the drain valve, thereby reducing the influence of the residual low-temperature water in the water outlet path on the user's water intake temperature and improving the temperature of the water actually obtained by the user. In addition, by making the height of the fluid path from the boost chamber to the hot water outlet in the vertical direction not lower than the residual water discharge branch, after the drain valve is opened, the residual water can automatically flow toward the residual water discharge branch under the action of gravity to achieve emptying.

[0019] 3. As a preferred embodiment of the present application, an exhaust pressure valve is installed on the pressure hot water tank. When the air pressure in the boosting chamber is less than the exhaust pressure value, the exhaust pressure valve closes the boosting chamber, so that the pressure in the boosting chamber can be increased through the continuously accumulated steam, thereby increasing the boiling point of the water in the boosting chamber; when the air pressure in the boosting chamber is greater than or equal to the exhaust pressure value, the exhaust pressure valve is opened to achieve exhaust, which plays an exhaust protection role and avoids the unlimited increase of the pressure in the boosting chamber and increases the risk of tank bursting.

[0020] 4. As a preferred embodiment of the present application, multiple safety pressure valves are installed on the pressure hot water tank, and the corresponding preset safety pressure values ​​of the multiple safety pressure valves increase in sequence from small to large, forming multiple safety protections, ensuring that in the event that a very individual safety pressure valve fails due to a malfunction, other safety pressure valves can still play a safety protection role, thereby ensuring the safe use of the pressure hot water tank.

[0021] 5. As a preferred embodiment of the present application, an air intake valve is installed in the pressure hot water tank so that when negative pressure occurs in the pressurized chamber during drainage due to its sealing, resulting in poor drainage, the air intake valve can be opened to balance the pressure of the outside atmosphere and the pressure in the pressurized chamber, thereby ensuring stable and smooth water discharge from the pressure hot water tank.

[0028] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0030] In addition, in the description of the present application, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", "lateral", "longitudinal", etc., indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0032] In the present application, unless otherwise clearly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0033] In the embodiment of the present application, a supercharged heat-purifying integrated machine is provided. For the convenience of explanation and understanding, the following contents provided in the present application are all described on the basis of the illustrated product structure. Of course, those skilled in the art can understand that the above structure is only used as a specific example and schematic description, and cannot constitute a specific limitation on the technical solution provided in the present application.

[0034] Reference Figures 1 to 3As shown, a pressurized integrated air conditioner and heat machine provided in the present application includes a filtering unit, a pressure hot water tank 13 and a heating structure, wherein: the filtering unit includes a filter element 11 and a booster pump 12 connected to the upstream water channel of the filter element 11, the pressure hot water tank 13 is provided with a sealable booster chamber, the booster chamber is used to store hot water and supply water to the hot water outlet of the integrated air conditioner and heat machine, and the hot water continuously increases the pressure in the booster chamber during the heating process, thereby increasing the heating boiling point; the heating structure can heat the clean water filtered and output by the filter element 11 and store it in the booster chamber.

[0035] Specifically, the water inlet path of the heat and air purifier can be controlled by the on-off of the water inlet valve 14. When the water inlet valve 14 is opened, the booster pump 12 is started, and the booster pump 12 can pump raw water into the filter element 11 for filtration. The clean water filtered by the filter element 11 can be heated by the heating structure and stored in the pressure hot water tank 13. When the user has a water demand, the hot water stored in the booster chamber can be directly or indirectly transported to the hot water outlet to achieve water supply, thereby improving the hot water outlet response capability of the whole machine. In order to enable the heat and air purifier to achieve the function of outputting normal temperature water, it can also be provided with a normal temperature water pipeline 15 connected to the clean water outlet of the filter element 11. The fluid path of the normal temperature water pipeline 15 is controlled by the normal temperature water valve 16. The outlet of the normal temperature water pipeline 15 and the hot water outlet can both be connected to the water outlet faucet 17.

[0036] The pressurized integrated heat and water purification machine provided in the present application has a pressure hot water tank 13 provided with a sealable boosting chamber, which is used to store hot water and supply water to the hot water outlet of the integrated heat and water purification machine. The heating structure can heat the clean water filtered and output by the filter element 11 and store it in the boosting chamber. Specifically, in the process of the heating structure heating the water, the boosting chamber can be sealed, and the backlog of water vapor continuously generated by the hot water in the boosting chamber increases the pressure in the boosting chamber, thereby increasing the boiling point of the water in the boosting chamber, so that the water temperature in the boosting chamber can be heated to above 100°C by the heating structure. Therefore, in the process of hot water above 100°C flowing toward the hot water outlet of the integrated heat and water purification machine, even if some heat is lost due to the mixing of the outlet pipe itself and the residual water inside it, the temperature of the hot water reaching the user's water container will be higher than 90°C, thereby effectively increasing the temperature of the water actually obtained by the user and meeting the user's demand for high-temperature boiling water close to 100°C. In addition, in the present solution, when the pressurized chamber is sealed, the contact with the outside air is effectively reduced, thereby reducing the risk of the water stored in the hot water tank being contaminated by bacteria in the air.

[0037] As a preferred implementation of the present application, Figure 1As shown, a pipeline residual water discharge branch 18 is connected to the fluid path from the boosting chamber to the hot water outlet, a drain valve 19 is provided on the fluid path of the pipeline residual water discharge branch 18, the pipeline residual water discharge branch 18 is connected to the waste water discharge port 20 of the heat and water purification machine, and the height of the fluid path from the boosting chamber to the hot water outlet in the vertical direction is not lower than that of the pipeline residual water discharge branch 18.

[0038] It is understood by those skilled in the art that the fluid path from the boost chamber to the hot water outlet is connected with a residual water discharge branch 18. When there is residual water on the fluid path from the boost chamber to the hot water outlet that has not been discharged through the hot water outlet, the residual water can be discharged through the residual water discharge branch 18 and the waste water discharge port 20 by opening the drain valve 19, thereby reducing the influence of the residual low-temperature water in the water outlet path on the user's water intake temperature when hot water is discharged again, and improving the temperature of the water actually obtained by the user. In addition, when the whole machine is assembled, the height of the fluid path from the boost chamber to the hot water outlet in the vertical direction is not lower than the residual water discharge branch 18. In other words, the water path structure of the boost chamber toward the hot water outlet is higher than the residual water discharge branch 18, so that after the drain valve 19 is opened, the residual water in the water path structure of the boost chamber toward the hot water outlet can automatically flow toward the residual water discharge branch 18 under the action of gravity to achieve emptying, thereby reducing the influence of the residual low-temperature water on the user's water intake temperature as much as possible. Specifically, the wastewater discharge port 20 can control the connection and disconnection of the waterway with the municipal sewer through the wastewater valve 21. When residual water needs to be discharged, both the drain valve 19 and the wastewater valve 21 need to be opened.

[0039] As a preferred implementation of the present application, Figure 1As shown, the pressure hot water tank 13 is installed with an exhaust pressure valve 22, and the exhaust pressure valve 22 has a preset exhaust pressure value. When the air pressure in the boost chamber is less than the exhaust pressure value, the exhaust pressure valve 22 closes the boost chamber, and when the air pressure in the boost chamber is greater than or equal to the exhaust pressure value, the exhaust pressure valve 22 is opened to achieve exhaust. It can be understood by those skilled in the art that, although the present solution utilizes the accumulation of steam in the boosting chamber to increase the pressure, the pressure in the boosting chamber cannot be increased indefinitely, otherwise the risk of tank bursting is increased. Therefore, by installing an exhaust pressure valve 22 on the pressure hot water tank 13, when the air pressure in the boosting chamber is less than the exhaust pressure value, the exhaust pressure valve 22 closes the boosting chamber, so that the boosting chamber can increase the pressure through the continuously accumulated steam, thereby increasing the heating boiling point of the water in the boosting chamber; when the air pressure in the boosting chamber is greater than or equal to the exhaust pressure value, the exhaust pressure valve 22 is opened to achieve exhaust, which plays an exhaust protection role and avoids the unlimited increase of the pressure in the boosting chamber and increases the risk of tank bursting; in addition, in the process of replenishing water into the boosting chamber through the filter element 11, the boosting chamber is initially in a closed state. As the amount of water in the boosting chamber continues to increase, the air pressure continues to increase, which increases the difficulty of replenishing water. When the air pressure is greater than or equal to the exhaust pressure value, the exhaust valve is opened to balance the boosting chamber and the external atmospheric pressure, thereby allowing the filter element 11 to continue to smoothly replenish water into the boosting chamber until the water level reaches the requirement. To ensure the boosting effect on the boost chamber when the exhaust pressure valve 22 is closed, the exhaust pressure value can be set at 20kPa-40kPa. The exhaust pressure valve 22 preferably has a gravity ball or gravity hammer structure, which has the advantages of stable pressure and not easy to decay.

[0040] Further preferably, the pressure hot water tank 13 is equipped with a plurality of safety pressure valves, and the plurality of safety pressure valves correspond to preset safety pressure values ​​that increase in sequence from small to large, and each of the safety pressure values ​​is greater than the exhaust pressure value. By installing a plurality of safety pressure valves on the pressure hot water tank 13, and the plurality of safety pressure valves correspond to preset safety pressure values ​​that increase in sequence from small to large, multiple safety protections are formed to ensure that in the event that a very few safety pressure valves fail due to a malfunction, other safety pressure valves can still play a safety protection role, thereby ensuring the safe use of the pressure hot water tank 13. This application does not limit the number of safety pressure valves, such as Figure 1As shown, the present application schematically illustrates an embodiment in which a pressure hot water tank 13 is equipped with a first safety pressure valve 23, a second safety pressure valve 24 and a third safety pressure valve 25, forming triple safety protection. The present scheme does not limit the pressure values ​​of the first safety pressure valve 23, the second safety pressure valve 24 and the third safety pressure valve 25. In a preferred embodiment, the pressure value of the first safety pressure valve 23 can be set to 1.5-2 times the exhaust pressure value, the pressure value of the second safety pressure valve 24 is 2 times the exhaust pressure value plus 20kPa-3.5 times the exhaust pressure value, and the third safety pressure valve 25 is not less than 6 times the exhaust pressure value plus 10kPa.

[0041] Further preferably, the structures of the plurality of safety pressure valves are different, and the safety pressure valves with preset maximum safety pressure values ​​among the plurality of safety pressure valves are configured as non-self-resetting structures. The structures of the plurality of safety pressure valves are different, that is, each safety pressure valve adopts a different structural scheme, which can effectively reduce the probability of failure at the same time when the same structural scheme is adopted. The safety pressure valves with preset maximum safety pressure values ​​among the plurality of safety pressure valves are configured as non-self-resetting structures. Taking the embodiment in which the pressure hot water tank 13 is installed with the first safety pressure valve 23, the second safety pressure valve 24 and the third safety pressure valve 25 as an example, the third safety pressure valve 25 is a structure with preset maximum safety pressure value. Setting it as a non-self-resetting structure means that as long as the pressure in the boosting chamber exceeds the safety pressure value of the third safety pressure valve 25 and the third safety pressure valve 25 is opened, it will not automatically reset to the closed state again, effectively ensuring the working safety of the pressure hot water tank 13. The third safety pressure valve 25 is preferably a non-self-resetting sealing plug structure.

[0042] As a preferred implementation of the present application, Figure 1 As shown, the pressure hot water tank 13 is equipped with an air inlet valve 26, and the air inlet valve 26 presets an air inlet pressure value. When the air pressure in the boosting chamber is less than or equal to the air inlet pressure value, the air inlet valve 26 opens to balance the pressure of the boosting chamber and the outside atmosphere. It can be understood by those skilled in the art that when the pressure hot water tank 13 is sealed, as the water in the boosting chamber is discharged, the pressure decreases accordingly. When it decreases to a negative pressure, it may be difficult to continue to discharge water. Therefore, the pressure hot water tank 13 is equipped with an air inlet valve 26, so that when the boosting chamber is sealed and a negative pressure occurs during the drainage process, resulting in poor drainage, the air inlet valve 26 can be opened to balance the pressure of the outside atmosphere and the pressure in the boosting chamber, ensuring that the water discharge of the pressure hot water tank 13 is stable and smooth. Specifically, the pressure value of the air inlet valve 26 is as small as possible, generally ≤10kPa. When the pressure in the pressure hot water tank 13 is less than the atmospheric pressure, the air inlet valve 26 opens to allow air to enter the pressure hot water tank 13.

[0043] As a preferred embodiment of the present application, the pressure hot water tank 13 is provided with a first water level detection device for detecting the water stop level in the boosting chamber and a second water level detection device for detecting the water replenishment level in the boosting chamber, and the water stop level is higher than the water replenishment level; when the water-purifying and heat-in-one machine detects the water stop level through the first water level detection device, the filter element 11 stops supplying water to the boosting chamber, and when the water-purifying and heat-in-one machine detects the water replenishment level through the second water level detection device, the filter element 11 starts supplying water to the boosting chamber. Specifically, the water stop water level can be set to a high water level according to actual needs. When the first water level detection device detects that the water level in the boosting chamber has reached the water stop water level, it means that the water level in the boosting chamber has reached the high water level that meets the water supply demand, and the whole system stops continuing to supply water into the boosting chamber; the water replenishment water level can be set to a low water level or a medium-low water level according to actual needs. When the second water level detection device detects that the water level in the boosting chamber has reached the water replenishment water level, it means that the amount of water in the boosting chamber is insufficient, and the whole system replenishes the boosting chamber with normal temperature water. After replenishing, the heating structure can be started for heating.

[0044] As a preferred implementation of the present application, Figure 1 As shown, the pressure hot water tank 13 is provided with a temperature detection device 27 for detecting the water temperature in the boosting chamber. When the heat and air purifier detects the first target temperature through the temperature detection device 27, the heating structure is controlled to heat the water in the boosting chamber to a second target temperature greater than the first target temperature. The temperature detection device 27 can feed back the water temperature in the boosting chamber to the control system in real time, so that the control system can control the whole machine to perform corresponding actions according to the water temperature. Preferably, in order to ensure that the temperature of the hot water reaching the user's water container is higher than 90°C, the second target water temperature can be selected from 102-105°C. By utilizing the boosting effect in the closed state of the boosting chamber, the heating structure can completely heat the water to 102-105°C. The first target temperature can be set according to actual needs, for example, it can be 70°C, 80°C, 90°C, etc. Once the temperature detection device detects that the water temperature in the boosting chamber is the first target temperature, the whole machine can control the heating structure to heat the water in the boosting chamber until the water temperature reaches the second target water temperature.

[0045] It should be noted that the present application does not limit the location of the heating structure. For example, the heating structure can be directly set in the pressure hot water tank 13, so that the filter element 11 can deliver normal temperature water to the boosting chamber and then the heating structure can directly heat the water in the boosting chamber; for another example, the heating structure can also be independently set outside the pressure hot water tank 13, and the water is delivered to the heating structure for heating and then returned to the pressure hot water tank 13 for storage. Specifically, regarding the arrangement of the heating structure, the present application provides the following embodiments:

[0046] Embodiment 1: Figure 1 As shown, the heating structure is a heating plate 28 arranged at the bottom of the boosting chamber, the clean water outlet of the filter element 11 is connected to the boosting chamber through the first water replenishment valve 29, and the boosting chamber is connected to the hot water outlet through the first water pump 30 and the water outlet valve 31 in turn.

[0047] In the present embodiment, when the second water level detection device detects that the water level in the boosting chamber is too low and the whole system needs to add water to the boosting chamber, the water inlet valve 14 and the first water replenishment valve 29 are opened, the boosting pump 12 is started, and the water enters the filter element 11 after being pressurized by the boosting pump 12. The water filtered by the filter element 11 enters the pressure hot water tank 13 through the first water replenishment valve 29. The heating structure heats the water. When the steam generated by the hot water squeezes the air in the pressure hot water tank 13 to increase the pressure in the pressure hot water tank 13 to the exhaust pressure value, the exhaust pressure valve 22 opens to exhaust so that water can continue to be injected into the pressure hot water tank 13. When the first water level detection device detects that the water level in the pressure hot water tank 13 reaches the water stop level, the water inlet valve 14 and the first water replenishment valve 29 are closed, the boosting pump 12 stops working, and the filter element 11 stops making water; when the temperature When the temperature detection device 27 detects that the water temperature in the pressure hot water tank 13 is lower than the target value (generally 102-105°C), the heating structure is started to heat the water in the pressure hot water tank 13. When the water temperature rises and water vapor is generated, the water vapor increases the internal pressure of the pressure hot water tank 13. When the pressure rises to the exhaust pressure value, the exhaust pressure valve 22 opens to exhaust. When the pressure drops to less than the pressure value of the exhaust pressure valve 22, the exhaust pressure valve 22 closes to maintain the pressure in the pressure hot water tank 13, so that the pressure in the pressure hot water tank 13 always has a certain pressure, so that the water temperature in the pressure hot water tank 13 can rise to a target temperature value above 100°C. When the temperature detection device 27 detects that the water temperature in the pressure hot water tank 13 reaches the target temperature value, the heating structure stops working and the heating structure no longer continues to heat the water. When the user needs to draw water, the water outlet valve 31 is opened, and the first water pump 30 also starts working. The first water pump 30 pressurizes the water, and at the same time, the pressure in the pressure hot water tank 13 is superimposed on the water to discharge the water, and the water flows to the water outlet tap 17, and the water is discharged from the water outlet tap 17; because the pressure hot water tank 13 is in a closed state, as the water in the pressure hot water tank 13 is discharged, the pressure in the pressure hot water tank 13 decreases accordingly. When it decreases to a negative pressure, it may make it difficult to continue to discharge water. The air inlet valve 26 is opened to allow the outside to intake air into the pressure hot water tank 13, so as to ensure that the water discharge from the pressure hot water tank 13 is stable and smooth. When the user has finished drawing water and has been on standby for a period of time (generally ≥5 minutes), the temperature of the residual water in the water pipe between the pressure hot water tank 13 and the water outlet tap 17 decreases. The low-temperature residual water at this time may affect the temperature of the user's next water drawing. At this time, open the drain valve 19 and the waste water valve 21 to allow the residual water in the water pipe to be discharged to the municipal sewer through the pipeline residual water discharge branch 18 under the action of gravity. After a period of time (generally 1 minute ≤ t ≤ 3 minutes) for the residual water in the water pipe to be drained, close the drain valve 19 and the waste water valve 21.

[0048] Embodiment 2: Figure 2As shown, the heating structure is a heating plate 28 arranged at the bottom of the boosting chamber, the clean water outlet of the filter element 11 is connected to the boosting chamber through the second water replenishing valve 32, the boosting chamber is connected to the water inlet of an instant heating body 35 through the first pressure reducing valve 33 and the second water pump 34 in turn, and the water outlet of the instant heating body 35 is connected to the hot water outlet; the clean water outlet of the filter element 11 is connected to the water inlet of the instant heating body 35 through the second pressure reducing valve 36 and the third water pump 37 in turn, and the second water pump 34 and the third water pump 37 selectively or together pump water to the instant heating body 35.

[0049] The difference between the second embodiment and the first embodiment is that an instant heating body 35 is arranged on the rear side of the water outlet waterway of the pressure hot water tank 13, and a normal temperature water waterway is connected in parallel at the front end of the instant heating body 35, a first pressure reducing valve 33 is arranged at the water outlet of the pressure hot water tank 13, the second water pump 34 adopts a diaphragm pump with adjustable flow, a second pressure reducing valve 36 is also arranged on the normal temperature water waterway, and the third water pump 37 also adopts a diaphragm pump with adjustable flow; the first pressure reducing valve 33 and the second pressure reducing valve 36 are used to reduce the pressure in the waterway, stabilize the pressure at the front ends of the second water pump 34 and the third water pump 37, so that the operation and flow regulation of the second water pump 34 and the third water pump 37 are relatively stable and accurate. This solution can adjust the outlet water temperature. When the user chooses 95-100℃ water outlet, the second water pump 34 directly draws water from the pressure hot water tank 13 and discharges water, and the heating body 35 does not need to work; when the user chooses 45-90℃ water outlet, the second water pump 34 draws water from the pressure hot water tank 13, and the third water pump 37 also draws water from the filter element 11. The two water paths are mixed at the front end of the heating body 35. By adjusting the current of the second water pump 34 and the third water pump 37, they have different flow rates, thereby obtaining different mixed water temperatures. Generally, the mixed water temperature = target water temperature - (5-15)℃, the mixed water enters the heating body 35, the heating body 35 also starts to work, and the water is heated to the target temperature before the water is discharged; when the user chooses 30-40℃ water outlet, the second water pump 34 does not need to be started, the third water pump 37 draws water from the filter element 11, the water enters the heating body 35, the heating body 35 starts to work, and the water is heated to the target temperature before the water is discharged.

[0050] Embodiment 3: Figure 3 As shown, the heating structure is an instant heating body 35, the clean water outlet of the filter element 11 is connected to the water inlet of the instant heating body 35 through the third pressure reducing valve 38 and the fourth water pump 39, the boosting chamber is connected to the water inlet of the instant heating body 35 through the fourth pressure reducing valve 40 and the fifth water pump 41 in turn, and the water outlet of the instant heating body 35 is connected to the boosting chamber through the third water replenishing valve 42 and connected to the hot water outlet through the hot water valve.

[0051] The difference between the third embodiment and the first embodiment is that the heating structure of the present solution is an instant heating body 35 independently outside the pressure hot water tank 13, and the water heated by the instant heating body 35 is returned to the pressure hot water tank 13 for storage by means of water circulation. Specifically, the third pressure reducing valve 38 and the third water replenishing valve 42 can be opened in advance, and the fourth water pump 39 pumps water from the filter element 11 into the instant heating body 35. The instant heating body 35 does not work but water can be replenished into the pressure hot water tank 13 through the third water replenishing valve 42 until the water in the pressure hot water tank 13 reaches the water stop level, and then the third pressure reducing valve 38 and the third water replenishing valve 42 are closed. When the temperature detection device 27 detects that the water temperature in the pressure hot water tank 13 is lower than the target value (generally 102-105°C), the fourth pressure reducing valve 40 and the third water supply valve 42 are opened, and the fifth water pump 41 starts to work to pump water from the pressure hot water tank 13. When the water passes through the instant heating body 35, the instant heating body 35 starts to work to heat the water. The heated water passes through the third water supply valve 42 and then flows back into the pressure hot water tank 13, thereby forming a circulating heating water circuit. When the water temperature in the pressure hot water tank 13 rises and water vapor is generated, the water vapor increases the internal pressure of the pressure hot water tank 13. When the pressure rises to the exhaust pressure value, , the exhaust pressure valve 22 is opened to exhaust. When the pressure drops to less than the exhaust pressure value, the exhaust pressure valve 22 is closed to maintain the pressure in the pressure hot water tank 13 and the circulating heating water circuit, so that the pressure hot water tank 13 and the circulating heating water circuit always have a certain pressure, so that the water temperature in the instant heating body 35 can rise to a target temperature value above 100°C. When the temperature detection device 27 detects that the water temperature in the pressure hot water tank 13 reaches the target temperature value, the instant heating body 35 and the fifth water pump 41 stop working, the fourth pressure reducing valve 40 and the third water supply valve 42 are closed, the circulating heating water circuit is closed, and the water heating is stopped.
