[0035] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0036] like Figure 1-14 As shown in the following embodiment, a combined air purifier and heat pump is disclosed.

[0037] Example 1 A combined air purifier and heating unit, comprising, The housing assembly is provided with an inlet and an outlet 2 for water intake and outlet; Located within the housing assembly and connected via the water channel plate 1, The raw water input unit is used to input external water sources into the water circuit inside the all-in-one machine for water supply; The purified water output unit is connected to the raw water input unit, and filters the externally input raw water to form purified water and outputs it in a quantitative manner; The ambient temperature water unit has its input end connected to the water purification unit, and its output end connected to the water outlet 2 on the housing assembly to output ambient temperature water. The hot water unit has its input end connected to the water purification unit and its output end connected to the water outlet 2 on the housing assembly to output hot water. The drainage unit has its input end connected to the water purification unit and its output end connected to the drain port of the housing assembly. The drainage unit and the ambient temperature water unit are opened in the same water output mode to output a fixed amount of ambient temperature water or warm water.

[0038] The above is the basic scheme of this embodiment.

[0039] Reference Figures 1-3 As shown, the housing assembly includes an outer shell 10 and a frame 20 disposed inside the outer shell 10. The frame 20 isolates the internal space of the outer shell 10 into multiple interconnected chambers. The upper surface of the outer shell 10 is configured as a control panel 10.1, which the user can operate to select water temperature, water volume, or water type. A control chamber is provided at the front of the frame 20, and a water circuit board 1 for installing water circuit control components is provided in the control chamber. The water circuit control components are components such as solenoid valves or pipes. The water circuit board 1 is provided with connectors that communicate with the water inlet on the outer shell 10, and the various water circuit units are connected by pipes. A water control end face 10.2 is provided on one end face of the outer shell 10 corresponding to the control chamber. The connectors on the water circuit board 1 extend to the water control end face 10.2 for connecting to an external water source or an external air source, and a water outlet connector 1.2 is provided to connect to a water outlet 2 for water dispensing.

[0040] The raw water input unit draws water from an external water source, which then enters the purified water output unit for purification, resulting in purified water that is output from the purified water outlet. The ambient temperature water output from the purified water output unit can enter the outlet 2 through the ambient temperature water unit for discharging ambient temperature water; alternatively, it can enter the hot water unit, where it is heated to a predetermined temperature range and stored. When hot water is needed, the hot water stored in the hot water unit is output from the outlet 2.

[0041] In this embodiment, during the process of storing hot water in the hot water unit, a temperature control structure can be set to control the water temperature in the hot water unit. When the water temperature is lower than the set temperature, the heating element 31.6 in the hot water unit will automatically turn on to heat the water stored inside and output it when needed.

[0042] When room temperature water needs to be output, turn on the raw water input unit, the purified water output unit, and the room temperature water unit; when hot water at the set temperature needs to be output, only the hot water unit needs to be turned on.

[0043] When warm water is needed, the control system inside the machine automatically calculates the required ratio of hot and cold water based on the temperature of the stored hot water and the user's selected water output. Simultaneously or sequentially, it outputs the corresponding amount of hot water and room temperature water to mix, thereby forming warm water at the desired temperature.

[0044] The output end of the water purification output unit is provided with a level valve 15 for adjusting the water output. The level valve 15 is located between the water purification output unit and the water circuit board 1, and preferably between the water circuit board 1 and the ambient temperature water solenoid valve 4. A flushing pipe is provided between the level valve 15 and the water purification output unit, and the flushing pipe is connected to the input end of the water purification output unit.

[0045] In the normal temperature water mode, the water output of the purified water output unit is controlled by setting the level valve 15. When the water output of the level valve 15 is set to the low level, the hot water unit and the drain unit are closed at the same time. The water volume of the set level enters the normal temperature water pipeline through the normal temperature water solenoid valve 4, and the remaining water cannot be discharged. So it enters the flushing pipe and is fed back into the purified water output unit to backwash the purified water output unit.

[0046] Based on the above settings, when the water output of the valve is at a low setting, the output of room temperature water is blocked, and the water output of the purified water output unit is also blocked. The purified water is output through the flushing pipe to relieve pressure at the purified water outlet, ensuring consistent pressure inside the purified water output unit and ensuring the purification effect.

[0047] In this embodiment, a specific implementation of mixing hot water and room temperature water is as follows: a drainage unit is provided for drainage, and the drainage unit and the room temperature water unit are turned on in the same mode to control the output of room temperature water.

[0048] When the water temperature selected by the user is inconsistent with the temperature of the hot water stored in the hot water unit and is lower than the stored hot water temperature, it is necessary to mix the hot water stored in the hot water unit with the room temperature water. That is, the hot water unit and the room temperature water unit are opened simultaneously or sequentially so that both room temperature water and hot water are output to the water outlet 2. In this embodiment, the water outlet 2 is provided with a room temperature water pipe and a hot water pipe 3, and the output ports of the room temperature water pipe and the hot water pipe 3 are mixed to form warm water, which is then output to containers such as water cups.

[0049] In this embodiment, after the control system calculates the ratio of hot water to cold water, the hot water unit is turned on and outputs the calculated amount of hot water. At the same time, the raw water input unit and the purified water output unit are turned on in sequence, and a certain amount of purified water is output from the purified water output unit. This amount of purified water is inconsistent with the amount of purified water required by the calculation. The drainage unit is turned on to drain the excess purified water, and the remaining purified water required by the calculation enters the ambient temperature water unit and is output to the water outlet 2, so that the water outlet 2 can output warm water with the same temperature and volume as the user selected.

[0050] In this embodiment, the ambient temperature water unit includes an ambient temperature water solenoid valve 4, and the drainage unit includes a drainage solenoid valve 12.

[0051] The input end of the ambient temperature water solenoid valve 4 and the output end of the purified water output unit are connected by a pipeline, and the output end of the ambient temperature water solenoid valve 4 and the water outlet 2 are connected by a water circuit board 1; the input end of the drain solenoid valve 12 is connected to the water outlet of the purified water output unit through the water circuit board 1, and the output end of the drain unit is connected to the drain port on the outer casing 10 through a drain pipe.

[0052] In this embodiment, the water purification output unit is a filter element 5, and the filter element 5 is provided with a wastewater pipeline for discharging wastewater, and a wastewater solenoid valve 6 is provided to control the opening and closing of the wastewater pipeline. The wastewater pipeline is connected to the wastewater connector 1.1 of the water circuit board 1.

[0053] In addition, in this embodiment, the raw water input unit includes an inlet solenoid valve 7 and a booster pump 8, which are connected in sequence between the inlet connector 1.3 of the water circuit board 1 and the purified water output unit.

[0054] The inlet solenoid valve 7 is installed on the water circuit board 1. Its inlet end is connected to the inlet connector 1.3 on the water circuit board 1, and its output end is connected to the booster pump 8. When the inlet solenoid valve 7 is opened, the external water source enters the water circuit of the machine through the inlet solenoid valve 7. After being pressurized by the booster pump 8, it enters the filter element 5 of the water purification output unit for filtration. The purified water formed after filtration is output from the output end to the normal temperature water unit, hot water unit, or drainage unit, etc. The wastewater containing impurities after filtration is discharged to the outside of the machine through the wastewater pipe on the filter element 5 from the wastewater connector 1.1 of the water circuit board 1.

[0055] Specific reference Figure 4 As shown, in the normal temperature water mode, the inlet solenoid valve 7 and the normal temperature water solenoid valve 4 are opened. The external water source passes through the inlet solenoid valve 7 and the booster pump 8 of the raw water input unit in sequence. After being purified by the filter element 5 of the purified water output unit, the purified water enters the normal temperature water unit. After passing through the normal temperature water solenoid valve 4 of the normal temperature water unit, it enters the outlet 2 along the normal temperature water pipeline for output.

[0056] In this embodiment, the hot water unit includes a hot tank 31 for heating and storing hot water. The output end of the hot tank 31 is equipped with a water pump 32 to output hot water to the water outlet connector 1.2 of the water circuit board 1. The hot tank 31 is equipped with an exhaust port and outputs hot water to the water outlet 2 through an exhaust pipe 13.

[0057] Specifically, the hot tank 31 is a commonly used heating and storage component in the prior art that can heat and store liquids. It has an exhaust port at its upper end, which is connected to an exhaust pipe 13. The output end of the exhaust pipe 13 is connected to the water outlet 2, so that the steam formed by heating water is output from the exhaust pipe 13 to ensure the stable air pressure inside the hot tank 31.

[0058] Meanwhile, a water pump 32 is installed at the bottom of the hot tank 31, which can provide power for the hot water stored in the hot tank 31 and output the hot water to the water outlet 2 through the hot water pipe 3.

[0059] In this embodiment, the hot water pipe 3, the normal temperature water pipe, and the exhaust pipe 13 are all connected to the water outlet connector 1.2, so that water and high temperature gas are output through the water outlet 2.

[0060] Specific reference Figure 5 As shown, in hot water mode, only the water pump 32 at the outlet of the hot tank 31 is turned on, and the water pump 32 outputs the hot water stored inside the hot tank 31 to the water outlet 2 through the hot water pipe 3.

[0061] When the user selects a water temperature between the hot water in the hot tank 31 and the room temperature water in the control panel 10.1, it is necessary to enter the mixing mode to mix the hot water and the room temperature water to obtain the water temperature and volume required by the user.

[0062] Specific reference Figure 6 As shown, in the mixing mode, the inlet solenoid valve 7, the ambient temperature water solenoid valve 4, and the drain solenoid valve 12 are all opened. At the same time, the water pump 32 at the bottom of the hot water tank 31 is turned on. The control system calculates the required ratio of hot water volume to ambient temperature water volume. The calculated water volume is drawn by the water pump 32 and output from the hot water pipe 3 to the water outlet 2. Meanwhile, based on the calculated required ambient temperature water volume, the opening time of the inlet solenoid valve 7 and the drain solenoid valve 12 is controlled to control the output of ambient temperature water in the ambient temperature pipe, thereby obtaining the required amount of ambient temperature water in the mixed water. The excess ambient temperature water is discharged from the drain pipe through the drain solenoid valve 12.

[0063] In this embodiment, the amount of water passing through is controlled by controlling the opening time of the ambient temperature water solenoid valve 4 and the drain solenoid valve 12. For example, the ambient temperature water solenoid valve 4 is opened for 1 second and the drain solenoid valve 12 is opened for 2 seconds, so that the ratio of the output amount of ambient temperature water to the output amount of drained water is 1:2.

[0064] In other embodiments, the mixing ratio can also be controlled directly by controlling the flow rates of the ambient temperature water solenoid valve 4 and the drain solenoid valve 12.

[0065] Reference Figures 7-10As shown, the exhaust port on the hot tank 31 is equipped with an exhaust liquefaction structure, which includes a condensate return component 31.1 fixed on the hot tank 31 and a steam exhaust pipe 31.2 installed on the condensate return component 31.1. The exhaust pipe 13 is connected to the steam exhaust pipe 31.2. The condensate return component 31.1 has a vapor-liquid mixing chamber 31.11. The steam exhaust pipe 31.2 has an exhaust passage 31.21 that connects to the vapor-liquid mixing chamber 31.11. The inlet end of the exhaust passage 31.21 is connected to the inner cavity of the hot tank 31 through the vapor-liquid mixing chamber 31.11. A condensate space 31.12 is formed between the inner wall of the vapor-liquid mixing chamber 31.11 and the outer wall of the steam exhaust pipe 31.2. Steam gathers on the inner wall of the condensate space 31.12 to form liquid and flows back to the hot tank 31 through the vapor-liquid mixing chamber 31.11.

[0066] A mounting portion 31.3 extends radially from the outer wall of the steam exhaust pipe 31.2. The steam exhaust pipe 31.2 is sealed to the condensate return component 31.1 via the mounting portion 31.3. The sealed connection between the end faces of the mounting portion 31.3 and the condensate return component 31.1 ensures that the condensate space 31.12 will not leak. Optionally, the ends of the mounting portion 31.3 and the condensate return component 31.1 can be connected by laser welding or plug-in connection. A guide component 31.4 is connected to one end of the condensate return component 31.1 near the exhaust passage 31.21. The guide component 31.4 has an interconnected steam inlet passage 31.41 and a liquid return hole 31.42. One end of the steam inlet passage 31.41 is connected to the hot tank 31, and the other end is connected to the vapor-liquid mixing chamber 31.11. The liquid return hole 31.42... .42 penetrates the side wall of the guide member 31.4 and communicates with the steam inlet channel 31.41. The liquid condensed and returned in the vapor-liquid mixing chamber 31.11 flows back to the hot tank 31 through the liquid return hole 31.42. Steam flows to the vapor-liquid mixing chamber 31.11 through the steam inlet channel 31.41. The liquid condensed in the condensate space 31.12 can slide down the inner wall of the vapor-liquid mixing chamber 31.11 to the liquid return hole 31.42 and flow back to the hot tank 31 for recycling. The condensate return member 31.1 includes a connecting part 31.13. One end of the vapor-liquid mixing chamber 31.11 passes through the connecting part 31.13. The guide member 31.4 is threadedly connected to the L-shaped connecting part 31.13, so that the condensate return member 31.1 can be detachably installed on the hot tank 31, which facilitates the replacement or cleaning of the condensate return member 31.1.

[0067] In this embodiment, a mounting hole is provided at the top of the hot tank 31 corresponding to the connecting part 31.13. After the connecting part 31.13 passes through the mounting hole, it is threadedly connected to the vertical section of the guide member 31.4, so that the guide member 31.4 and the condensate return member 31.1 together hold the top of the hot tank 31. Furthermore, the bottom surface of the condensate space 31.12 is provided with a guide slope 31.121 from the position away from the connecting part 31.13 toward the direction close to the connecting part 31.13. Water droplets condensed on the inner wall of the condensate space 31.12 can be gathered to the connecting part 31.13 by the guide slope 31.121, and flow to the vertical section of the guide member 31.4 through the vapor-liquid mixing chamber 31.11 of the connecting part 31.13.

[0068] The steam inlet channel 31.41 has an L-shaped channel structure, and the inlet end of the horizontal section is closer to the top of the hot tank 31, thus ensuring that the steam at the top of the hot tank 31 can preferentially enter the inlet end of the steam inlet channel 31.41. Optionally, the inner diameter of the horizontal section is larger than the liquid return hole 31.42, thus ensuring that the steam can enter the steam inlet channel 31.41 from the inlet end of the horizontal section in a large flow. The liquid return hole 31.42 is connected to the bottom of the horizontal section of the L-shaped channel structure, and the liquid return hole 31.42 is set close to the vertical section. The liquid return hole 31.42 is located within the vertical projection area of ​​the vertical section, so that the liquid returning from the condensate space 31.12 passes through the vertical section and directly flows back to the hot tank 31 from the liquid return hole 31.42 at the bottom of the vertical section, improving the efficiency of the return liquid flowing back to the hot tank 31.

[0069] It should be noted that in this embodiment, when using the hot water mode, the hot water tank 31 already contains a set capacity of hot water, and the temperature selected by the user is consistent with the storage temperature of the hot water tank 31.

[0070] When the water level in the hot water tank 31 is lower than the set value, water needs to be replenished through the raw water output unit and the purified water output unit.

[0071] A water supply valve 33 is provided between the hot tank 31 and the purified water output unit. A water level detection device is provided inside the hot tank 31. The water level detection device and the water supply valve 33 are used in conjunction.

[0072] Specific reference Figure 7As shown, the water level detection device includes several water level probes 31.5. The water level detection device is located on the top of the hot tank 31 and near the center. The venting and liquefaction structure of the hot tank 31 is installed on the top of the hot tank 31 and spaced apart on the side of the water level detection device. The water level detection module can monitor the water level in the hot tank 31 in real time. In addition, placing the water level detection device at the center of the top of the hot tank 31 can improve the accuracy of the water level detection module in detecting the water level in the hot tank 31. At the same time, the spaced arrangement of the venting and liquefaction structure of the hot tank 31 on the side of the water level detection device is beneficial to improving the modularity of the various functions integrated in this embodiment. The heating element 31.6 of the hot tank 31 is located at the bottom of the tank to form a heating area 31.61. The vertical projection of the water level detection device overlaps with the heating area 31.61. The heating element 31.6 is used to heat the heating area 31.61, thereby realizing the heating of the liquid in the hot tank 31 to prepare hot water. In this embodiment, the heating area 31.61 is aligned. The steam discharge pipe 31.2 is positioned below the water level detection device, which improves the uniformity of hot water heating in various areas of the hot tank 31. The steam discharge pipe 31.2 is arranged horizontally relative to the hot tank 31, so that the steam discharge direction of the steam discharge channel 31.21 is perpendicular to the arrangement direction of the water level probe 31.5. Unlike the vertically arranged steam discharge pipe 31.2, which easily leads to the direct upward discharge of steam and a large steam loss, this embodiment arranges the steam discharge pipe 31.2 horizontally relative to the hot tank 31. This allows the steam from the top of the hot tank 31 to be lifted upward through the vapor-liquid mixing chamber 31.11 and then bend and change direction through the horizontally arranged steam discharge pipe 31.2, thereby slowing down the steam discharge rate. This allows the steam to have more opportunities to contact the inner wall of the vapor-liquid mixing chamber 31.11 and the outer wall of the steam discharge pipe 31.2, so that more steam can condense on the inner wall of the condensate space 31.12 to form a backflow liquid, thereby reducing the steam loss when the hot tank 31 is depressurized.

[0073] When the water level in the hot tank 31 falls below the set value, the control system automatically switches the water circuit system to water replenishment mode. Figure 11 As shown, the inlet solenoid valve 7 and the replenishment solenoid valve are open, the booster pump 8 is turned on, and the water pump 32 on the hot water tank 31 is turned off. External raw water passes through the inlet solenoid valve 7 and the booster pump 8 of the raw water input unit in sequence, and enters the purified water output unit for filtration and purification. The purified water is output, passes through the water circuit board 1, and enters the hot water unit. After passing through the hot water solenoid valve, it enters the hot water tank 31 to replenish the hot water tank 31. At the same time, the heating element 31.6 in the hot water tank 31 is energized to heat the purified water in the hot water tank 31 to the set temperature and store it.

[0074] Example 2 This embodiment is an improvement on embodiment 1, and its purpose is to process excess water in the water replenishment mode. The specific implementation method is as follows: In this embodiment, the drain solenoid valve and the water supply valve are used together to regulate the amount of water input into the hot tank.

[0075] The drain solenoid valve 12, the water supply valve 33, and the ambient temperature water solenoid valve 4 are all connected to the water circuit board 1.

[0076] In the water replenishment mode, when the amount of water replenished to the hot tank 31 is lower than the amount of water output from the filter element 5, the control system controls the drain solenoid valve 12 to open and discharge the excess purified water through the drain solenoid valve 12.

[0077] The way in which the drain solenoid valve 12 and the water supply valve 33 control the water volume ratio is the same as the way in which the drain solenoid valve 12 and the ambient temperature water solenoid valve 4 are controlled, and will not be described in detail here.

[0078] Example 3 This embodiment is an improvement based on Embodiment 1 or Embodiment 2, and its purpose is to provide a method for heating hot water so that users can access hot water at high temperatures. The specific implementation method is as follows: Typically, to reduce resource waste, the heat storage temperature inside the heat tank 31 is not set very high, but rather within the optimal heat storage temperature range. However, if the user requires hot water at a temperature higher than the heat storage temperature, the hot water inside the heat tank 31 needs to be heated so that it can output high-temperature hot water.

[0079] Therefore, in this embodiment, the hot water unit further includes a heating element 9, which is connected to the hot water pipeline 3 of the hot water tank 31 and the water outlet 2 to reheat the hot water output from the hot water tank 31.

[0080] In this embodiment, the heating element 9 can be installed on the hot water pipe 3 or inside the water outlet 2 to heat the output hot water.

[0081] Preferably, in this embodiment, the heating element 9 is a fast-heating element commonly used in the prior art.

[0082] In the rapid heating mode, only the water pump 32 and the heating element 9 at the bottom of the hot tank 31 are turned on. The hot water in the hot tank 31 is drawn to the hot water pipe 3 by the water pump 32. During the output process along the hot water pipe 3, it passes through the heating element 9 and absorbs a large amount of heat generated by the heating element 9, forming high-temperature hot water that is output from the water outlet 2.

[0083] Example 4 This embodiment is an improvement based on the above embodiments. Its purpose is to treat residual water in the water system, reduce resource waste, and ensure water safety. The specific implementation method is as follows: In this embodiment, in order to reduce the residual water in the pipes inside the machine body, resulting in residual water being output the next time it is used, a return unit is connected in parallel to the water purification output unit. The return unit includes a return solenoid valve 41 and a one-way valve 42 arranged sequentially along the water flow direction. The input end of the return solenoid valve 41 is connected to the output end of the water purification output unit.

[0084] The input end of the return solenoid valve 41 is connected to the water circuit board 1, and is also connected to the input ends of the drain solenoid valve and the water supply solenoid valve. The output end of the check valve 42 is connected to the input end of the booster pump 8.

[0085] Reference Figure 12 As shown, in the normal temperature water state or the water replenishment state, the water inlet solenoid valve 7 is opened, and a certain amount of purified water is output from the filter element 5. This amount of purified water is output to the water outlet 2 through the normal temperature water unit, or enters the hot water unit to replenish the hot water tank 31, or part of it is used for discharge and part of it is mixed with water through the normal temperature water unit. In any water output mode, the amount of purified water output from the filter element 5 is usually greater than the required amount of water. Therefore, a small amount of water will remain in the pipeline. In this embodiment, the small amount of water enters the return unit, passes through the return solenoid valve 41 and the one-way valve 42 in sequence along the return pipeline, and enters the purified water output unit again through the booster pump 8 for filtration again. At the same time, the filter membrane inside the filter element 5 is backwashed.

[0086] The backwashing with purified water can flush out impurities and microorganisms trapped inside filter element 5, preventing them from remaining inside. This solves the problem of frequent replacement due to filter element 5 clogging and prevents these substances from multiplying and fermenting inside the filter element 5, causing secondary pollution. After the backwashing, filter element 5 is immersed in purified water. The high purity of the purified water provides virtually no nutrients for microorganisms, effectively inhibiting their growth and ensuring the health of the user's water. Due to the low ion concentration of the purified water, it can also dissolve the high concentration of ion crystals adhering to filter element 5, preventing clogging and protecting filter element 5, thereby extending its service life.

[0087] In this embodiment, filter element 5 is a composite filter element.

[0088] The one-way valve 42 in the return unit ensures that the returned purified water can only flow back from the output end of the filter element 5 to the output end of the booster pump 8, and cannot flow in the opposite direction. In conjunction with the booster pump 8, it also prevents the presence of unreturned purified water in the return pipeline.

[0089] Example 5 This embodiment is an improvement based on the above embodiments. Its purpose is to increase the functionality of the all-in-one machine and make it more versatile. The specific implementation method is as follows: In this embodiment, a bubble water unit is also provided, and the outlet of the bubble water unit is connected to the water outlet 2, so that bubble water is directly output from the water outlet 2.

[0090] The bubble water unit includes a pressure reducing valve 51, a bubble module 52, and a bubble water solenoid valve 53 connected in sequence, and the pressure reducing valve 51 is connected to the water inlet; The bubble module 52 includes at least an ejector 52.1 with an air inlet channel 52.112. Gas and raw water are mixed under the action of the ejector 52.1 and output to the booster pump 8.

[0091] The principle of bubble water production by bubble module 52 is as follows: gas is input from the air inlet 1.4, and the gas enters the ejector 52.1 under the action of water circuit plate 1 and pipe fittings. At the same time, raw water is input into the same chamber as the gas. In this chamber, the gas and raw water are mixed to produce bubble water.

[0092] The jet injector 52.1 is a gas-liquid mixing device. Its main function is to achieve efficient mixing between different fluids by utilizing the movement of the fluid itself through a special structural design. The design of the jet injector allows it to achieve efficient mixing by relying solely on the movement of the fluid without any moving parts during operation.

[0093] Specific reference Figure 14 As shown, the jet injector 52.1 includes an outer housing 52.11, on which a water inlet channel 52.111 and an air inlet channel 52.112 are provided, and both the water inlet channel 52.111 and the air inlet channel 52.112 are connected to the jet chamber inside the jet injector 52.1; a booster 52.12 and a mixer 52.13 are provided inside the jet chamber. The input end of the booster 52.12 is connected to the water inlet channel 52.111 and is used to pressurize the raw water; the mixer 52.13 is connected to the air inlet channel 52.112 and the input channel of the booster 52.12, and mixes the raw water and gas to form bubble water.

[0094] Specifically, the booster 52.12 has a booster channel 52.121 inside, and the booster channel 52.121 is configured with a constricted structure along the raw water input direction; The mixer 52.13 has a mixing channel 52.131 inside, and the mixing channel 52.131 is configured with a flared structure along the direction of water flow.

[0095] Raw water enters the booster 52.12 through the inlet channel. Under the action of the booster channel 52.121, it is injected at high speed into the mixing channel 52.131, creating a negative pressure in the mixing channel 52.131 and producing a siphon effect. As a result, the air in the air intake channel 52.112 is drawn into the mixing channel 52.131 and mixes with the raw water in the mixing channel 52.131 to form bubble water.

[0096] In this embodiment, the head of the mixer 52.13 extends with an air inlet sleeve 52.132, and an air inlet chamber 52.1321 is formed inside the air inlet sleeve 52.132. The booster 52.12 is disposed inside the air inlet chamber 52.1321, and a space capable of accommodating gas is formed between the outer wall of the booster 52.12 and the air inlet sleeve 52.132. The air inlet sleeve 52.132 is provided with air holes that communicate with the air inlet channel 52.112.

[0097] A baffle 52.14 is formed between the air intake chamber 52.1321 and the mixing channel 52.131. The input end of the mixing channel 52.131 is a small hole formed in the baffle 52.14. A gap is formed between the baffle 52.14 and the output end of the booster 52.12, which can accommodate gas entering the small hole.

[0098] When the output end of the booster channel 52.121 sprays fluid toward the orifice, a negative pressure is formed near the orifice, and the air in the intake channel 52.121 is drawn in toward the center, thus entering the mixing channel 52.131 with the high-speed airflow.

[0099] In this embodiment, the inlet of the pressure reducing valve 51 is connected to the inlet connector 1.3 of the water control end face 10.2 via the water circuit board 1, allowing external raw water to directly enter the bubble water unit from the pressure reducing valve 51. The air inlet channel 52.112 of the ejector 52.1 is connected to the air inlet of the water control end face 10.2, allowing gas to be input from the outside. Simultaneously, the output of the ejector 52.1 is connected to the booster pump 8 of the raw water input unit, pressurizing the mixed bubble water before outputting it to the outlet 2.

[0100] Furthermore, in order to reduce water waste and prevent raw water from entering the water purification output unit, in this embodiment, the water purification output unit also includes a water lock valve 11, which is located at the input end of the water purification output unit to close the input end of the water purification output unit.

[0101] The water-locking valve 11 is located between the booster pump 8 and the filter element 5.

[0102] The bubble module 52 and the water outlet 2 are connected by a bubble water pipeline. The bubble water solenoid valve 53 is located on the bubble water pipeline and is used to control the opening and closing of the input end of the water purification unit.

[0103] In this embodiment, a bubbler 14 is connected to the bubble water pipeline.

[0104] Preferably, in this embodiment, the bubble module 52 is further provided with a spare tank 52.2. The spare tank 52.2 is connected between the booster pump 8 and the bubble water solenoid valve 53. The bubble water pressurized by the booster pump 8 enters the bubble water pipeline after passing through the spare tank 52.2.

[0105] Reference Figure 13 As shown, in the sparkling water mode, the inlet solenoid valve 7 of the raw water input unit is closed, and the water lock valve 11 is also closed. The external water source inputs raw water into the machine body, which directly enters the ejector 52.1 of the bubble module 52 through the pressure reducing valve 51. At the same time, the air intake channel 52.112 inputs gas into the ejector 52.1. The pressure-reduced raw water and the pressurized gas after passing through the ejector 52.1 mix to form sparkling water, which enters the booster pump 8 through the pipeline. After being pressurized, it passes through the spare tank 52.2 along the pipeline, and then through the sparkling water solenoid valve 53 before being output from the sparkling water pipeline to the water outlet 2 for sparkling water output.

[0106] In this embodiment, a check valve 53 is provided in the air inlet channel 52.112 of the bubble module 52 to prevent the gas input into the bubble module 52 from being output in reverse, thus ensuring the normal operation of the bubble module 52.

[0107] Example 6 This embodiment provides a water mixing method, applied to the integrated water purifier and heat dissipation machine described in the above embodiments, including the following steps: S1. The control system receives the water temperature and water volume input by the user; S2. Obtain the water temperature and volume stored in the hot water unit; S3. Based on the information obtained, determine whether it is necessary to mix the water. S4. In cases where mixing is required, calculate the ratio of hot water to room temperature water needed for mixing. S5. Calculate the ratio of water volume required by the ambient temperature water unit and the drainage unit based on the water volume output by the water purification output unit. S6. Turn on the hot water unit, the ambient temperature water unit and the drain unit, and control the opening time of the ambient temperature water solenoid valve 4 and the drain solenoid valve 12.

[0108] In step S3, the control system can proceed to the next step only when the water temperature and volume stored in the hot water unit obtained by the control system do not match the water temperature and volume input by the user, and when the water temperature input by the user is lower than the water temperature stored in the hot water unit.

[0109] In steps S4 and S5, the water output of the purified water output unit is the set value of the machine body, which has been stored in the control system. The sum of the water output of the room temperature water unit and the water output of the drainage unit is the water output of the purified water output unit.

[0110] In step S5, the amount of hot water required by the hot water unit can be controlled by the amount of hot water that can be output from the room temperature water unit; or the amount of hot water required by the room temperature water unit can be controlled by the amount of hot water that can be output from the hot water unit.

[0111] In step S6, the ambient temperature water unit and the drainage unit can be turned on simultaneously, and their respective closing times can be set according to the water output; they can also be turned on alternately, with the opening time ratio set according to the required water volume ratio; or they can be turned on one after the other, with one of them turning on after the required water volume is reached.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
