Description

Technical Field

[0001] This application relates to the field of water preparation technology, and more specifically, to a device for producing water using air. Background Technology

[0002] To overcome water pollution and expand water sources, air-to-water generators have been invented. These generators work by recycling and purifying atmospheric water for use. For example, Chinese invention patent CN105735416B discloses a remotely controllable air-purifying water generator that sequentially passes air through a non-woven fabric filter layer, a high-efficiency particulate air filter layer made of needle-punched cotton, an activated carbon treatment layer, and a nano-Ag layer. + After coating and applying a TiO2 photocatalytic filter layer, water is produced by condensation in an evaporator. This technology currently has the following shortcomings that need to be addressed:

[0003] 1. Activated carbon treatment layer, nano Ag + The coating and TiO2 photocatalytic filter layer are spaced apart, preventing airborne bacteria from being fully killed by the nano-silver. Some bacteria, after passing through the nano-silver coating, will be absorbed by the nano-Ag. + The bacteria in the coating and TiO2 photocatalytic filter layer reactivate or proliferate, and the sterilization rate can only reach 70-80% due to the gap structure. At the same time, the bacteria that pass through the TiO2 photocatalytic filter layer will produce an odor after being killed, and the ultraviolet light will also produce a pungent odor. These odors cannot be removed.

[0004] 2. The evaporator and condenser are directly connected by a capillary tube. When the refrigerant pressure through the capillary tube is too high or the compressor temperature is too high, the high-pressure or high-temperature refrigerant can easily damage the evaporator.

[0005] 3. The motor of the existing fan unit is located in the air path, which obstructs the air intake and reduces the efficiency of water-electricity conversion.

[0006] 4. The equipment does not have a dedicated ammonia and nitrogen removal device, and cannot effectively remove ammonia and nitrogen from the cooling water.

[0007] 5. The water tank of the existing water purifier is used for water storage. When the water is stored for too long, bacteria will grow in the water, but there is a lack of sterilization methods.

[0008] 6. When the existing water purifier starts dispensing hot water, the water that comes out is still cold because it cannot be fully heated by the instant heater. This part of the water cannot be recycled. At the same time, if the instant heater heats a lot of water, and the amount of water dispensed is small, the excess water in the instant heater cannot be recycled, which can easily breed bacteria. Moreover, when the instant heater is turned on again, the excess water is usually discharged as cold water because the heating time is short, which wastes water resources.

[0009] 7. Existing air-to-water direct drinking machines still use Freon for refrigeration. Waste Freon is emitted into the atmosphere, which is detrimental to the protection of the ozone layer and has low energy efficiency. At present, the emerging magnetic refrigeration technology that does not use Freon is rarely used in the field of air-to-water direct drinking machines. Summary of the Invention

[0010] This application provides an air-to-water device that can solve the above-mentioned problems. The technical solution is as follows:

[0011] An air-to-water direct drinking water machine includes a filtration unit, which comprises a first activated carbon filter layer, a second activated carbon filter layer, and nano-Ag. + The coating, TiO2 photocatalytic filter, and ultraviolet light-emitting device are included, with nano-Ag particles seamlessly disposed on one side of the first activated carbon filter layer. + The coating, the nano Ag + A TiO2 photocatalytic filter is installed without gaps on one side of the coating.

[0019] The turbine fan has multiple symmetrical diamond-shaped ventilation holes on the side wall facing away from the air passage. These holes are used to allow air to pass through the turbine fan and cool the motor. The symmetrical design of the multiple diamond-shaped ventilation holes is to cancel out wind noise.

[0028] The water receiving tray is equipped with a nano-filtration device layer inside;

[0035] Furthermore, it also includes a condenser, a heat exchanger, piping one, piping two, solenoid valve one, an electromagnet, a magnetic refrigerant, a heat exchange medium, an air pump, a liquid supply tank, solenoid valve three, a water pump three, a pressure sensor, and a water level sensor two.

[0036] The condenser box is equipped with a magnetic refrigerant. Multiple vertical pipes are opened on the magnetic refrigerant perpendicular to the bottom plate of the condenser box. The magnetic refrigerant is spaced a certain distance from the bottom plate of the condenser box to form a gap that connects with the multiple vertical pipes. The gap and the multiple vertical pipes are filled with heat exchange medium.

[0037] There is a certain distance between the magnetic refrigerant and the top plate of the condenser. The top plate is connected to the heat exchange box through a pipe 1.

[0040] Electromagnets are symmetrically arranged on the outside of the condenser boxes on both sides of the magnetic refrigerant.

[0041] The second pipeline connects to the condenser box at a location below the side wall of the condenser box;

[0042] The outer peripheral wall of the condenser is integrally connected with a condenser mesh to increase the air cooling area. The outer peripheral wall and the condenser mesh are made of a metal material with good heat transfer performance, such as Cu or Fe.

[0043] Furthermore, it also includes a water receiving tray, a nano-filtration device layer, a lower water tank, a water pump, a water filter element, a water filter element, a water filter element, a UV sterilizing lamp, an upper water tank, an outlet water pump, a water filter element, a UV sterilizing lamp, a four-way valve A, a return pipe 2, a three-way valve C, an instant heater, a return pipe 1, a single-way valve, a float and a water level sensor, and a fan device, which includes a turbine fan, a motor, and a motor mounting plate.

[0044] The water collection tray is used to collect the condensate generated by the condensation of air in the condensation box. The condensate flows into the lower water tank connected to the water collection tray, and then passes through water pump one, water filter one, water filter two, water filter three, ultraviolet germicidal lamp one, upper water tank, water pump, water filter four, and ultraviolet germicidal lamp two in sequence before entering the four-way valve A. The four-way valve A is connected to the three-way valve C. The three-way valve C is connected to the hot water inlet and the outlet of the instant heater respectively. The outlet of the instant heater is also connected to the hot water inlet of the instant heater.

[0045] The four-way valve A is also connected to the upper water tank via a return pipe;

[0046] In one scenario, the four-way valve A is open, the three-way valve C is open, and the condensate flows directly into the instant heater after passing through the aforementioned path.

[0047] In another scenario, the four-way valve A is opened and the three-way valve C is closed, drawing water from the upper water tank at regular intervals. The water is then filtered by the four water quality filter cartridges and disinfected by the two ultraviolet germicidal lamps before being returned to the upper water tank through the two return pipes, ensuring that the water quality in the upper water tank meets the standards.

[0054] It also includes a fan unit, which is used to generate negative pressure so that outside air is sequentially drawn into the filter section and condenser of the air-to-water direct drinking machine;

[0055] The turbine fan is installed between the filter section and the condenser box. The three are arranged in an L-shape to form an L-shaped branch. The turbine fan, condenser box and water collection tray are arranged in sequence from top to bottom along the air path.

[0056] The motor is mounted on a mounting plate on the side of the turbine fan facing away from the air passage to avoid obstructing the airflow. Multiple symmetrically arranged diamond-shaped ventilation holes are provided on the side wall of the turbine fan facing away from the air passage to allow air to pass through and cool the motor. The symmetrical design of the multiple diamond-shaped ventilation holes is to cancel out wind noise.

[0057] The solenoid valve 1, solenoid valve 2, electromagnet, air pump, water level sensor 2, pressure sensor, detection unit, outlet pump, water pump 1, water pump 2, water pump 3, ultraviolet germicidal lamp 1, ultraviolet germicidal lamp 2, four-way valve A, three-way valve C, three-way valve D, instant heater, water level sensor 1, single-way valve, turbine fan and motor 1 are respectively connected to the control unit, which is at least one of MCU or programmable logic controller.

[0058] A method for preparing the filter section of an air-to-water direct drinking water machine includes the following steps:

[0059] 1) Prepare an aluminum profile frame by placing the aluminum profile frame into an injection mold and filling it with injection molding to form a fixed frame with openings on the top and opposite side walls.

[0060] 2) Nano Ag + The coating was uniformly sprayed onto the TiO2 photocatalytic filter, and then UV light was used to irradiate the nano-Ag. + The coating is cured according to the first activated carbon filter layer and nano Ag. + The coating, TiO2 photocatalytic filter, isolation column, ultraviolet lamp plate, and second activated carbon filter layer are stacked together in sequence to form a laminate, the total thickness of which is slightly greater than the length of the upper opening of the fixed frame.

[0061] 3) Heat the fixed frame. The plastic on it softens and deforms when heated. The length of the upper opening becomes slightly longer. At this time, insert the laminate from step 2) into the fixed frame along the length of the upper opening and tighten it. After the plastic cools and shrinks, the laminate will be pressed tightly together at the upper opening.

[0062] Furthermore, the nano-Ag + The coating thickness is 1-2mm, the UV light irradiation time is 45 minutes, the length of the isolation column is 3.5-4mm, the width of the UV lamp board is 3mm, and the UV lamp is an LED lamp bead.

[0063] The present invention has the following beneficial effects:

[0064] 1. By tightly pressing the activated carbon treatment layer, the nano-Ag+ coating, and the TiO2 photocatalytic filter together, eliminating the gaps between different layers, and spraying the nano-Ag+ coating to a certain thickness onto the TiO2 photocatalytic filter, bacteria are simultaneously captured and killed by both the nano-Ag+ coating and the TiO2 photocatalyst when they adhere to the nano-Ag+ coating. This results in strong and thorough killing, eliminating any bacteria that are not fully disinfected and will pass through the nano-silver coating and be absorbed by the nano-Ag+. + The gap between the coating and the TiO2 photocatalytic filter layer has the opportunity to reactivate or proliferate again. Experiments have shown that the filter section prepared using the above parameters and the process described in this paper has an effective sterilization rate of up to 90%, while the current filter section with spaced settings has an effective sterilization rate of only 70-80%. At the same time, bacteria that pass through the TiO2 photocatalytic filter layer will produce an odor after being killed, and ultraviolet light will also produce a pungent odor. These odors can be effectively removed by the second activated carbon filter layer placed later.

[0065] 2. When the control unit detects that the refrigerant pressure or temperature through the capillary tube of the expansion valve is too high (corresponding to excessively high compressor temperature), it will open the relief valve in a pulse or pulse width modulation manner. That is, the opening and closing time is periodically adjusted to divert the refrigerant through the capillary tube of the expansion valve and direct it to the low-pressure side of the compressor. This avoids high-pressure or high-temperature refrigerant from easily damaging the compressor or causing the tube to burst. At the same time, it avoids the continuous opening of the relief valve, which would cause the refrigerant flow to mainly pass through the relief valve and not pass through the expansion valve or capillary tube, resulting in insufficient refrigerant evaporation in the evaporator.

[0066] 3. The motor of the existing fan unit is located on the side wall of the fan unit facing away from the air passage, which does not obstruct the air intake and improves the water-electricity conversion efficiency. At the same time, the ventilation holes on the fan unit can still play the role of cooling the fan.

[0067] 4. The water filter cartridge is made of natural resin, which is used to filter nitrogen from the condensate.

[0068] 5. In this application, the water generator controls the water purifier so that when the water in the instant heater reaches a certain amount, its float rises and connects to the return pipe, allowing the accumulated water to be recycled back to the lower water tank. This avoids the problem of excess water in the instant heater being discharged as cold water due to its short heating time, which wastes water resources and breeds bacteria.

[0069] 6. Every 4 hours, the control unit will activate the three-way valve A, water filter cartridge four, ultraviolet sterilization lamp two, and water pump to filter and disinfect the water in the upper water tank through the return pipe two, ensuring water quality.

[0070] 7. It can accurately control the water volume in the upper and lower water tanks.

[0071] 8. Existing air-to-water direct drinking machines still use Freon for refrigeration, and the waste Freon is emitted into the atmosphere, which is not conducive to the protection of the ozone layer and has a low energy efficiency ratio. This embodiment creatively applies magnetic refrigeration technology to the field of air-to-water direct drinking machines, which protects the ozone layer and has a high refrigeration energy efficiency ratio.

[0072] 9. The magnetic refrigeration technology of this application is ingeniously conceived. It can complete the refrigeration cycle without moving the magnetic refrigeration working fluid. It has low operating noise, small space occupation, and low environmental requirements, making it suitable for use in air-to-water direct drinking machines.

[0073] 10. The heat released by magnetic refrigeration can be recovered and reused, saving electricity.

[0074] 11. By setting at least one of a water level sensor and a pressure sensor or a humidity sensor, in conjunction with valves, water pumps and control units, the entire refrigeration process can be precisely controlled. At the same time, by adopting the heat exchange medium absorption and circulation heat exchange method, the heat exchange medium always overflows the upper surface of the magnetic refrigerant when absorbing heat, so that the ambient temperature around the condenser is always kept at a low temperature, which is conducive to the continuous and efficient condensation process.

[0091] Example 1

[0092] like Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, an air-to-water direct drinking water machine includes a filtration unit, which comprises a first activated carbon filter layer 11, a second activated carbon filter layer 13, and a nano-Ag sprayed coating. + The TiO2 photocatalytic filter layer 12 is coated, and nano-Ag is disposed on one side of the first activated carbon filter layer 11 without gaps 212. + The coating, the nano Ag + A TiO2 photocatalytic filter is provided on one side of the coating without gap 212. A second activated carbon treatment layer is provided on one side of the TiO2 photocatalytic filter with gap 212. An ultraviolet light-emitting device is provided in the gap 212.

[0093] The width of the gap 212 is 3.5-6.5 mm, and the width of the ultraviolet light-emitting device is 3-5 mm. The nano-Ag... +The coating thickness is 1-2mm, the length of the isolation column 32 is 3.5-4mm, the width of the ultraviolet lamp plate 38 is 3mm, and the ultraviolet lamp is an LED lamp bead.

[0094] By using activated carbon treatment layer, nano Ag + The coating and TiO2 photocatalytic filter are tightly pressed together, eliminating the gaps between different layers, and nano-Ag is then incorporated. + The coating is sprayed onto the TiO2 photocatalytic filter at a certain thickness, allowing bacteria to attach nano-Ag. + During coating, simultaneously subjected to nano-Ag + The coating and TiO2 photocatalytic killing have a strong killing effect and are thorough in eliminating bacteria. Some bacteria that were not fully disinfected will be eliminated after passing through the nano-silver coating and will be absorbed by the nano-Ag. + The gap 212 between the coating and the TiO2 photocatalytic filter layer has the opportunity to revive or proliferate again. Experiments have shown that the filter section prepared using the above parameters and the process described in this paper has an effective sterilization rate of up to 90%, while the current filter section with interval settings has an effective sterilization rate of only 70-80%. At the same time, bacteria that pass through the TiO2 photocatalytic filter layer will produce an odor after being killed, and ultraviolet light will also produce a pungent odor. These odors can be effectively removed by the second activated carbon filter layer 13 set later.

[0095] It also includes an evaporator 14, a condenser 15, a compressor 16, a throttle valve 18, a relief valve 110, a relief pipe, and a detection unit. The condenser 15 is connected to the evaporator 14 via the throttle valve 18. One end of the pressure relief pipe 17 is connected to the condenser 15. The pressure relief pipe 17 is sequentially connected to the detection unit, the relief valve 110, and the low-pressure end of the air compressor 16. The low-pressure end of the air compressor 16 is also connected to the evaporator 14, and the high-pressure end of the compressor 16 is connected to the condenser 15.

[0096] The evaporator 14, condenser 15, compressor 16, throttle valve 18, relief valve 110, and detection unit are respectively connected to a control unit, which is at least one of an MCU or a programmable logic controller; the detection unit is either a pressure switch 19 or a temperature sensor. Alternatively, the throttle valve 18 can be replaced by a capillary assembly.

[0097] When the control unit detects that the refrigerant pressure or temperature through the capillary tube of the expansion valve 18 is too high or too high (corresponding to excessively high temperature of the compressor 16), it will open the relief valve 110 in a pulse or pulse width modulation manner. That is, the opening and closing time is periodically adjusted, for example, opening for 3 minutes and closing for 5 minutes, to divert the refrigerant through the capillary tube of the expansion valve 18 to the low-pressure end of the compressor 16. This avoids the compressor or tube bursting caused by high-pressure or high-temperature refrigerant. At the same time, it avoids the continuous opening of the relief valve 110, which would cause the refrigerant flow to mainly flow through the relief valve 110 and not pass through the expansion valve 18 or the capillary tube assembly, resulting in insufficient refrigerant evaporation in the evaporator 14.

[0098] The connection of evaporator 14, condenser 15, and compressor 16 for refrigeration is common knowledge in this field and will not be elaborated further.

[0099] See appendix Figure 7 It also includes a fan device 132, which generates negative pressure so that outside air is sequentially drawn into the filter section, evaporator 14 and condenser 15 of the air-to-water direct drinking machine.

[0100] The fan unit includes a fan mounting plate 1321, a noise reduction plate 1322, an electret microphone 1323, a turbine fan 1324, a first motor 133, a second motor 1325, and a first motor fixing plate 1326.

[0101] The filter section, evaporator 14, condenser 15, fan mounting plate 1321, noise reduction plate 1322, turbine fan 1324, motor 133 and motor mounting plate 1326 are arranged sequentially from front to back along the air path. Currently, the motor 133 of the fan device 132 is located on the air path to ensure that it can be cooled, but it blocks the air intake and reduces the water-electricity conversion efficiency. In this embodiment, the motor 133 is located on the motor mounting plate 1326 on the side of the turbine fan 1324 facing away from the air path to avoid the motor 133 blocking the airflow.

[0102] The turbine fan 1324 has multiple symmetrical diamond-shaped ventilation holes 1327 on the side wall facing away from the air passage. These holes are used to allow air to pass through the turbine fan 1324 and cool the motor 133. The symmetrical design of the multiple diamond-shaped ventilation holes 1327 is to cancel out wind noise.

[0103] The noise reduction plate 1322 is also connected to a second motor 1325 and an electret microphone 1323 respectively. The second motor 1325 and the electret microphone 1323 are mounted on the first motor fixing plate 1326.

[0104] The motor 133, motor 2 1325, turbine fan 1324 and electret microphone 1323 are respectively connected to the control unit, which is at least one of MCU or programmable logic controller.

[0105] When the electret microphone 1323 detects wind noise exceeding the threshold, it sends a signal to the control unit, which then controls the motor 1325 to rotate the noise reduction plate 1322 relative to the ventilation hole of the fan mounting plate 1321, thereby adjusting the direction and speed of the wind passing through the ventilation hole and reducing noise.

[0106] It also includes a water receiving tray 111, a nano-filtration device layer, a lower water tank 112, a water pump 1, a water filter element 114, a water filter element 2 115, a water filter element 3 116, an ultraviolet germicidal lamp 117, an upper water tank 118, an outlet water pump 129, a water filter element 4 127, an ultraviolet germicidal lamp 2 128, a three-way valve A 119, a return pipe 2 126, a three-way valve B 120, an instant heater 121, and also includes a return pipe 125, a single-way valve 124, a float 135, and a water level sensor 130;

[0107] The water receiving tray 111 is used to collect the condensate generated by the condensation of air in the evaporator. The condensate flows into the lower water tank 112 connected to the water receiving tray 111, and passes in sequence through water pump one, water filter element one 114, water filter element two 115, water filter element three 116, ultraviolet germicidal lamp one 117, upper water tank 118, water pump 129, water filter element four 127, and ultraviolet germicidal lamp two 128 before entering the three-way valve A119. The three-way valve A119 is connected to the three-way valve B120. The three-way valve B120 is connected to the instant heater hot water inlet 122 and the instant heater outlet 123 respectively. The instant heater outlet 123 is also connected to the instant heater hot water inlet 122.

[0108] The three-way valve A119 is also connected to the upper water tank 118 via the return pipe 126;

[0109] In one scenario, the three-way valve A119 is open, the three-way valve B120 is open, and the condensate flows directly into the instant heater 121 after passing through the aforementioned path.

[0110] In another scenario, the three-way valve A119 is opened and the three-way valve B120 is closed, drawing water from the upper water tank 118 every 4 hours. The water is then filtered by the water quality filter cartridge 127 and disinfected by the ultraviolet germicidal lamp 128 before being returned to the upper water tank 118 via the return pipe 126, ensuring that the water quality in the upper water tank 118 meets the standards.

[0111] Water filter cartridge 316 is made of natural resin, and this natural resin filter cartridge is used to filter nitrogen in condensate;

[0112] The water receiving tray 111 is equipped with a nano-filtration device layer inside;

[0113] The water pump 1, water outlet pump 129, ultraviolet germicidal lamp 117, ultraviolet germicidal lamp 2 128, three-way valve A119, three-way valve B120 and instant heater 121 are respectively connected to the control unit, which is at least one of MCU or programmable logic controller.

[0114] It also includes a return pipe 125, a one-way valve 124, a float and a water level sensor 130;

[0115] The instant water heater 121 is directly connected to the lower water tank 112 through a return pipe 125. A one-way valve 124 is installed on the return pipe 125. A float is installed inside the instant water heater 121.

[0116] The water pump is a Dengyuan pump 113;

[0117] Both the lower water tank 112 and the upper water tank 118 are equipped with water level sensors 130.

[0118] The water level sensor 130 and the one-way valve 124 are respectively connected to the control unit, which is at least one of an MCU or a programmable logic controller.

[0119] In existing water purifiers, the water that is just starting to dispense hot water is still cold because the instantaneous heater 121 cannot heat it sufficiently. This portion of water cannot be recycled. At the same time, if the instantaneous heater 121 heats a large amount of water but the flow rate is small, the excess water in the instantaneous heater 121 cannot be recycled, which can easily lead to bacterial growth. However, the water purifier of this application only needs to accumulate a certain amount of water in the instantaneous heater 121. When the float 135 rises, it connects to the return pipe 125, and the accumulated water can be recycled to the lower water tank 112. This avoids the problem of excess water being discharged as cold water due to short heating time, which wastes water resources and breeds bacteria.

[0120] The water level sensor 130 and the one-way valve 124 are respectively connected to the control unit, which is at least one of an MCU or a programmable logic controller.

[0121] Generally, the water level in both the lower water tank 112 and the upper water tank 118 is controlled by a water level sensor to not exceed 50%. The lower water tank 112 has a reserve for water to return to the instant water heater. When the water level exceeds 50%, the control unit controls the lower water tank 112 to supply water to the upper water tank 118. When the water level in the upper water tank 118 is too high, it will also control the water to return to the lower water tank 112. If both tanks are full, an alarm will be triggered.

[0122] Example 2

[0123] like Figure 3 , Figure 4 , Figure 5, Figure 6 As shown, the difference from Embodiment 1 lies in the refrigeration equipment and the corresponding pipeline design. This embodiment uses a magnetic refrigeration equipment, which includes a condenser box 22, a heat exchange box 26, a first pipeline 24, a second pipeline 216, a first solenoid valve 215, an electromagnet 21, a magnetic refrigerant 213, a heat exchange medium 211, and an air pump 25. The magnetic refrigerant 213 is fixed inside the condenser box 22. Multiple vertical pipes 222 are opened on the magnetic refrigerant 213 perpendicular to the bottom plate of the condenser box 22. The magnetic refrigerant 213 is set at a certain distance from the bottom plate of the condenser box 22 to form a gap 212 that connects with the multiple vertical pipes 222. The gap 212 and the multiple vertical pipes 222 are all filled with heat exchange medium 211.

[0124] The magnetic refrigerant 213 has a certain distance from the top plate of the condenser 22, forming a steam channel 214. The top plate is connected to the heat exchange box 26 through a pipe 24. The bottom of the heat exchange box 26 is connected to the condenser 22 through a pipe 216. A solenoid valve 215 is installed on the pipe 216.

[0125] Electromagnets 21 are symmetrically arranged on the outside of the condenser boxes 22 on both sides of the magnetic refrigerant 213;

[0126] The first pipeline 24 is also connected to an air pump 25, the second pipeline 216 is also connected to a vacuum tube 210, the vacuum tube 210 is also connected to a solenoid valve 219, the bottom of the condenser box 22 is equipped with a water level sensor 131, the heat exchange box 26 is equipped with at least one of a pressure sensor or a humidity sensor, and the heat exchange medium 211 is either water or oil.

[0127] The second pipe 216 is located below the side wall of the condenser box 22.

[0128] The outer peripheral wall of the condenser box 22 is integrally connected with a condenser mesh 23 to increase the air cooling area. The outer peripheral wall and the condenser mesh 23 are made of a metal material with good heat transfer performance, such as Cu or Fe.

[0129] It also includes a liquid supply tank 217, a third solenoid valve 220, and a third water pump 218. The second pipeline 216 is provided with a first solenoid valve 215, a liquid supply tank 217, a third water pump 218, a third solenoid valve 220, a vacuum tube 210 and a condenser 22 in sequence in the direction towards the condenser 22.

[0130] The heat exchange box 26 is connected to a mesh heat exchange tube 221. The inlet of the heat exchange tube 221 is connected to the water pump 28 and the four-way valve A27 in sequence. The outlet of the heat exchange tube 221 is connected to the three-way valve D223. The three-way valve D223 is connected to the water tank and the hot water outlet 122 of the instant heater respectively.

[0131] The working principle of the above-mentioned magnetic refrigeration equipment is as follows:

[0132] First, the control unit controls the electromagnet 21 to magnetize the magnetic refrigerant 213, which begins to release heat (common knowledge of the magnetocaloric effect). The heat is absorbed by the heat exchange medium 211 and evaporates into the heat exchange box 26. The air pump 25 is activated by the control unit to accelerate the air extraction. The heat exchange medium 211 entering the heat exchange box 26 transfers heat to the surrounding environment or the condensate in the heat exchange tube 221 (activated by the control unit as needed). The heat exchange medium 211 is then reliquefied and stored in the heat exchange box 26. During the heat release process of the magnetic refrigerant 213, the control unit controls the liquid supply tank 217 to ensure that the heat exchange medium 211 inside the heat exchange box 26 is always supplied, ensuring that the magnetic refrigerant 213 does not release excessive heat to the environment around the condenser box 22, thus maintaining a low-temperature environment around the condenser box 22.

[0133] Next, the control unit controls the electromagnet 21 to stop magnetizing the magnetic refrigerant 213, which begins to absorb heat (common knowledge of magnetocaloric effect). At this time, the control unit controls the condenser 22 and the heat exchanger 26 to simultaneously return liquid heat exchange medium 211 to the liquid supply tank 217, ensuring that the magnetic refrigerant 213 in the condenser 22 can fully absorb heat from the air entering the condenser 22 through the long and densely wound condenser tubes, producing condensate water that flows into the water receiving tray 111 below. At the same time, the liquid supply tank 217 returns enough liquid heat exchange medium 211 to ensure the supply of heat exchange medium 211 in the condenser 22 during the next magnetization.

[0134] Finally, the heat absorption and release process is repeated, continuously producing condensate. The water level sensor 131 is used to detect whether the water level in the condensation tank 22 meets the standard and sends a signal to the control unit to control whether the liquid supply tank 217 supplies liquid. The heat exchange tank 26 is equipped with at least one of a pressure sensor or a humidity sensor to determine whether the steam of the heat exchange medium 211 inside it has been fully condensed and whether it meets the standard for returning to the liquid supply tank 217.

[0135] Some of the hot water from the outlet of heat exchange tube 221 can be used directly, while some can be stored in the upper water tank.

[0136] Another difference lies in the piping structure of heat exchanger 26, as detailed below:

[0137] The multi-way valve includes a four-way valve A27 (replacing the three-way valve A119 in Embodiment 1) and a three-way valve C29 (replacing the three-way valve B120 in Embodiment 1). The upper water tank 118 is connected to the four-way valve A27, the four-way valve A27 is connected to the three-way valve C29, and the three-way valve C29 is connected to the hot water inlet 122 and the hot water outlet 123 of the instant heater respectively.

[0138] The four-way valve A27 is also connected to the ultraviolet germicidal lamp 128 and the water tank 118 respectively;

[0139] The heat exchange box 26 is connected to a mesh heat exchange tube 221. The inlet of the heat exchange tube 221 is connected to the second water pump 28 and the four-way valve A27 in sequence. The outlet of the heat exchange tube 221 is connected to the three-way valve D223. The three-way valve D223 is connected to the upper water tank 118 and the instant water outlet 123 respectively (that is, in this embodiment, the three-way valve A in the first embodiment is modified to the four-way valve A27, the three-way valve B in the first embodiment is modified to the three-way valve C, and the heat exchange tube is added as a heat exchange pipeline, as well as the three-way valve D223 on the pipeline, and its connection relationship with the upper water tank 118 and the instant water outlet).

[0140] The control unit controls water pump 28, four-way valve A27, and three-way valve D223 to draw water from the upper water tank 118 into the heat exchange tube 221 for heat exchange, and then returns the heated water to the upper water tank 118 for storage or flows into the outlet 123 of the instant water heater for use, so as to save energy.

[0141] As can be seen from the above, the solenoid valve 215, solenoid valve 219, electromagnet 21, air pump 25, water level sensor 131, at least one of pressure sensor or humidity sensor, detection unit, water pump 1, water pump 28, water pump 3 218, water sterilization and disinfection device, multi-way valve, instant heater 121, water level sensor 130, single-way valve 124, four-way valve A27, three-way valve C29, and three-way valve D223 are respectively connected to the control unit, which is at least one of MCU or programmable logic controller.

[0142] Existing air-to-water direct drinking machines still use Freon for refrigeration, and the waste Freon is emitted into the atmosphere, which is not conducive to the protection of the ozone layer and has a low energy efficiency ratio. This embodiment creatively applies magnetic refrigeration technology to the field of air-to-water direct drinking machines, which protects the ozone layer and has a high refrigeration energy efficiency ratio.

[0143] By setting at least one of a water level sensor and a pressure sensor or a humidity sensor, along with valves, water pumps and control units, the entire refrigeration process can be precisely controlled. At the same time, by using heat exchange medium 211 to absorb heat and circulate heat exchange, the heat exchange medium 211 always overflows the upper surface of the magnetic refrigerant 213 when absorbing heat, so that the ambient temperature around the condenser 22 is always kept at a low temperature, which is conducive to the continuous and efficient condensation process.

[0144] The magnetic refrigeration technology of this application is ingeniously conceived. It can complete the refrigeration cycle without moving the magnetic refrigeration working fluid 213. It has low operating noise, small space occupation, and low environmental requirements, making it suitable for use in air-to-water direct drinking machines.

[0145] In addition, with the attached Figure 4The difference lies in the fact that the heat exchange medium 211 completely surrounds the outer wall of the magnetic refrigerant (i.e., the magnetic refrigerant does not contact the side and bottom walls of the condenser 22), or even the magnetic refrigerant is made into granules and placed in a loose, porous device, allowing the heat exchange medium 211 to be completely immersed between different particles. This improves the heat absorption effect of the heat exchange medium, ensuring that the ambient temperature around the condenser 22 remains at a low temperature. This is an easily conceived and feasible approach. Magnetic refrigerants operating at room temperature are also currently existing technology.

[0146] Example 3

[0147] like Figure 1 , Figure 5 and Figure 6 As shown, the preparation method of the filter section of the air-to-water direct drinking machine in Examples 1 and 2 includes the following steps:

[0149] 2) Nano Ag + The coating was uniformly sprayed onto the TiO2 photocatalytic filter, and then UV light was used to irradiate the nano-Ag. + Coating curing, preparation of sprayed nano Ag + The TiO2 photocatalytic filter 31 with coating, according to the first activated carbon filter layer 11 and nano Ag + The coating, TiO2 photocatalytic filter, isolation column 32, ultraviolet lamp plate 38, and second activated carbon filter layer 13 are stacked together in sequence to form a laminated layer, the total thickness of which is slightly greater than the length of the upper opening 36 of the fixed frame 35.

[0150] 3) Heat the fixed frame 35. The plastic 34 on it softens and deforms due to the heat. The length of the upper opening 36 becomes slightly longer. At this time, insert the laminated layer from step 2) into the fixed frame 35 along the length of the upper opening 36 and tighten it. After the plastic 34 cools and shrinks, the laminated layer will be tightly pressed together at the upper opening 36.

[0151] The nano Ag + The coating thickness is 1-2 mm, and the UV light irradiation time is 45 minutes to fully cure the nano-Ag. + The coating has a length of 3.5-4mm for the isolation column 32, a width of 3mm for the ultraviolet lamp plate 38, and the ultraviolet lamp is an LED lamp bead.

[0152] Air mainly enters the filter section through the side wall opening 37 of the fixed frame 35 for filtration and disinfection.

The method for preparing the filter section of the air-to-water direct drinking machine according to any one of claims 1-7, characterized in that, Includes the following steps: 1) Prepare an aluminum profile frame by placing the aluminum profile frame into an injection mold and filling it with injection molding to form a fixed frame with openings on the top and opposite side walls. 2) Nano Ag + The coating was uniformly sprayed onto the TiO2 photocatalytic filter, and then UV light was used to irradiate the nano-Ag. + The coating is cured according to the first activated carbon filter layer and nano Ag. + The coating, TiO2 photocatalytic filter, isolation column, ultraviolet lamp plate, and second activated carbon filter layer are stacked together in sequence to form a laminate, the total thickness of which is slightly greater than the length of the upper opening of the fixed frame. 3) Heat the fixed frame. The plastic on it softens and deforms due to the heat. The length of the upper opening becomes slightly longer. At this time, insert the laminate from step 2) into the fixed frame along the length of the upper opening and tighten it. After the plastic cools and shrinks, the laminate will be pressed tightly together at the upper opening.
