Typically, it purifies water that is not suitable for direct drinking, filtering out impurities, bacteria, and toxic substances to produce drinking water that meets healthy drinking standards. The water source for a water maker can be tap water or river water. When the air temperature is high, water can be produced by liquefying moisture from the air. For example, on a ship at sea, due to the high humidity in the air and the fact that seawater cannot be directly consumed, liquefying water vapor from the air to produce fresh water before using it in a water maker is more convenient and can also reduce humidity.

[0003] The air water making machine in the related technology includes a compression mechanism, a condenser and an evaporator. The refrigerant output end of the compression mechanism is connected to the input end pipeline of the condenser, the output end of the condenser is connected to the input end pipeline of the evaporator, and the output end of the evaporator is connected to the refrigerant input end pipeline of the compression mechanism. The refrigerant forms a circulation loop between the compression mechanism, condenser and evaporator; a water tank is provided under the evaporator; the water tank pipeline is connected to a water pump, and the water pump pipeline is connected to a physical filtration system; when the air passes through the evaporator, it is liquefied, and the liquefied water flows into the water tank, and then when it needs to be drunk, it is pumped into the physical filtration system for filtration, thereby achieving the purpose of making water from the air.

[0004] However, in the above structure, bacteria in the air are easy to grow after entering the evaporator and condenser, causing the water entering the water tank to deteriorate easily, making the physical filter system need to be replaced more frequently. Summary of the Invention

[0005] In order to reduce the growth of bacteria and thereby reduce the frequency of replacing the physical filtration system, the present application provides an air water generator.

At the same time, the water mist at the evaporator can be fully combined with the sterilization gas, and the fan is turned off, so that a larger amount of sterilization gas is mixed in the water droplets adsorbed on the evaporator, so that the condensation box and the evaporator can obtain better sterilization effects, reduce the breeding of bacteria, and thus reduce the burden on the physical filtration system, thereby reducing the frequency of replacement of the physical filtration system.

[0009] Preferably, a filter grille and a composite filter screen are provided in the front box; the filter grille is installed at the air inlet; the filtering accuracy of the composite filter screen is less than the filtering accuracy of the filter grille; the composite filter screen includes a filter screen layer and an activated carbon layer; the filter screen layer is located on the side of the activated carbon layer close to the filter grille.

[0010] By adopting the above technical solution, the filter grille is installed at the air inlet, and the air is first filtered by the filter grille and then passes through the composite filter screen. The filter layer in the composite filter screen can further filter foreign matter in the air. By cleaning the filter grille, the replacement frequency of the composite filter screen can be reduced.

[0019] Preferably, the electronic refrigeration bladder is cooled by a semiconductor refrigeration sheet, and the housing is provided with an air outlet corresponding to the electronic refrigeration bladder and used for dissipating heat from the electronic refrigeration bladder; the heating element is a thick film heating body.

[0020] By adopting the above technical solution, the electronic refrigeration ice chamber adopts semiconductor refrigeration sheets, and the heating element adopts thick film heating body, so that the lowering and raising of water temperature are completed by electricity, reducing the volume of equipment for water production and dehumidification at the same time.

[0028] 1. The sterilizing gas stored in the storage tank is sprayed into the front box through the release nozzle installed on the front box. At the same time, the fan can also send the sterilizing gas to the evaporator. At the same time, the water mist at the evaporator can fully combine with the sterilizing gas. Turning off the fan allows the water droplets adsorbed on the evaporator to be mixed with a larger amount of sterilizing gas, so that the condensation box and evaporator can achieve better sterilization effects, reduce bacterial growth, and thus reduce the burden on the physical filtration system, thereby reducing the frequency of replacing the physical filtration system;

[0029] 2. The photocatalyst filter is located on the side close to the UV lamp, so that the light of the UV lamp can shine on the photocatalyst filter.

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] The present application discloses an air water making machine, referring to Figure 1 , including a casing 1, a condensation box 2 is provided inside the casing 1, one side of the condensation box 2 is open and faces the side wall of the casing 1, an air inlet 11 is provided on the side wall of the casing 1, and the opening side of the condensation box 2 is connected to the air inlet 11 on the casing 1, and a fan 3 is provided on the side of the condensation box 2 away from the opening, and the fan 3 is used to suck the air outside the casing 1 into the condensation box 2, and then draw it out of the condensation box 2 through the fan 3; the air outlet end of the fan 3 is connected to the soundproofing bellows 31, and an air outlet 12 is provided at the bottom of the casing 1, and the air outlet end of the fan 3 is connected to the air outlet 12 through the soundproofing bellows 31, so that the air can pass through the condensation box 2 and then be discharged from the air outlet 12 at the bottom of the casing 1.

[0039] refer to Figure 1 and Figure 2An evaporator 21 and a condenser 22 are provided in the condenser box 2. The evaporator 21 and the condenser 22 are sequentially arranged on the air flow channel in the condenser box 2, so that the condenser 22 is located between the evaporator 21 and the fan 3; a compressor 23 is provided in the casing 1, so that the refrigerant output port of the compressor 23 is connected to the pipeline of the condenser 22, and the condenser 22 is connected to the evaporator 21 by a pipeline, and then the evaporator 21 is connected to the refrigerant input port of the compressor 23, so that the refrigerant cools the air when passing through the evaporator 21, so that the moisture in the air condenses on the evaporator 21, and then the air flow reduces the refrigerant temperature in the condenser 22 when passing through the condenser 22, and the air temperature rises again, thereby reducing the change in indoor air temperature and reducing the power consumption when the compressor 23 is working.

[0040] refer to Figure 1 A downwardly recessed collection trough 24 is formed at the bottom of the condenser tank 2. A water tank 4 is located below the collection trough 24. A pipeline connects the water tank 4 to the collection trough 24, allowing the water condensed from the evaporator 21 in the collection trough 24 to flow into the water tank 4. A drain port 41 is located at the bottom of the water tank 4, connecting to the exterior of the housing 1. When the water in the water tank 4 needs to be drained, the drain port 41 can be opened to conveniently clean the water tank 4. When the water in the water tank 4 needs to be collected, the drain port 41 is closed. A water pump 5 is fixedly installed inside the housing 1. The water suction end of the water pump 5 is connected to the interior of the water tank 4, allowing the water pump 5 to pump water from the water tank 4. A water outlet solenoid valve 51 is located inside the housing 1 to control the outflow of water pumped by the water pump 5.

[0041] refer to Figure 1 and Figure 3An electronic cooling bladder 52 and a heating element 53 are fixedly mounted within the housing 1. The electronic cooling bladder 52 is cooled by semiconductor cooling chips. Air outlets 13 corresponding to the electronic cooling bladder 52 are provided in the housing 1. Heat generated by the electronic cooling bladder 52 is discharged through the air outlets 13 on the housing 1, thereby cooling the water flowing through the electronic cooling bladder 52. The heating element 53 is a thick-film heater that heats the water passing through it. A water outlet 54 is installed on the outside of the casing 1. There are two water outlets 54, one for discharging hot water and the other for discharging cold water. A physical filtration system 6 is fixedly arranged on the casing 1. The physical filtration system 6 is a five-stage ultrafiltration filter. There are multiple water outlet solenoid valves 51. The water outlet end of the water pump 5 is first connected to the physical filtration system 6, and the physical filtration system 6 is then connected to the water outlet solenoid valve 51. The water outlet solenoid valve 51 is connected to the electronic refrigeration ice bladder 52 or the heating body, and the water outlet 54 is then connected to the water outlet end of the electronic refrigeration ice bladder 52 or the heating body, so that the water pumped out by the water pump 5 is first filtered by the physical filtration system 6, and then enters the electronic refrigeration ice bladder 52 for cooling or the heating body for heating, and then flows out from the position of the water outlet 54, thereby achieving the effect of making it convenient for users to connect hot water or cold water.

[0042] refer to Figure 4A front box 7 is disposed between the condenser box 2 and the housing 1. The front box 7 is a box body that extends from front to back. One end of the front box 7 is fixedly connected to the housing 1, connecting the front box 7 to the air inlet 11. The front box 7 is connected to the opening of the condenser box 2, so that the front box 7 is used to connect the condenser box 2 and the air inlet 11 on the housing 1. After air enters through the air inlet 11, it first enters the front box 7 and then enters the condenser box 2. A release nozzle 81 is disposed at the bottom of the front box 7. A through hole 71 is formed in the bottom of the front box 7, so that the end of the release nozzle 81 enters the through hole 71. The release nozzle 81 is used to spray sterilizing gas into the front box 7. The sterilizing gas can be sulfur dioxide. A storage tank 82 is fixedly mounted on the inner wall of the housing 1. Storage tank 82 is used to store sterilizing gas. A release solenoid valve 83 is also fixedly mounted on the inner wall of the housing 1. One end of release solenoid valve 83 is connected to the gas outlet of storage tank 82, and the other end is connected to release nozzle 81. During use, release solenoid valve 83 is opened, and the sterilizing gas in storage tank 82 enters release nozzle 81 through release solenoid valve 83. Release nozzle 81 then sprays the sterilizing gas into pre-tank 7. Sulfur dioxide, when used as the sterilizing gas, combines with the water mist in evaporator 21 to form a liquid with a sterilizing effect. This liquid can also be distributed relatively evenly within condenser tank 2, thereby sterilizing the interior of condenser tank 2 and evaporator 21. This reduces the risk of bacteria breeding due to moisture in condenser tank 2, which affects water quality, and reduces the frequency of replacement of physical filtration system 6. During use, the fan 3 is turned on first, and then the evaporator 21 and the condenser 22 work normally. When water mist is formed in the evaporator 21, sterilizing gas is sprayed into the forward box 7. After the sterilizing gas enters the condensing box 2, the fan 3, the compressor 23 and the release solenoid valve 83 are turned off, so that the water mist in the condensing box 2 can combine with the sterilizing gas for a period of time, so that the sterilizing gas can fully enter the water mist, thereby improving the sterilization effect on the evaporator 21 and reducing the sterilizing gas contained in the air. Then the fan 3 is turned on again, and the evaporator 21 is cleaned by the water condensed by the evaporator 21, and the sewage flows into the water tank 4 and is discharged from the sewage outlet 41 of the water tank 4.

[0043] refer to Figure 5The front box 7 is provided with a filter grille 91, a composite filter screen 92, and an ultraviolet lamp 93. The ultraviolet lamp 93 is vertically fixed to the side wall of the front box 7. Two ultraviolet lamps 93 are provided and arranged on opposite sides of the airflow. The ultraviolet lamps 93 remain on during the process of the airflow passing through the front box 7, so that the ultraviolet lamps 93 can kill bacteria in the airflow, reducing the bacterial content in the water condensed by the evaporator 21, thereby improving the water quality and storage time, and also reducing the replacement frequency of the physical filtration system 6. The ultraviolet lamp 93 is set on one side of the composite filter screen 92, and the filter grille 91 is set on the other side; the filter grille 91 is located at the air inlet 11 of the housing 1, so that the airflow first passes through the filter grille 91, then passes through the composite filter screen 92, and finally enters the condensation box 2 after being sterilized by the ultraviolet lamp 93. The filtering accuracy of the filter grating 91 is 0.1 mm. The filter grating 91 is mainly used to remove dust and floating objects in the air and reduce the blockage of the composite filter screen 92 by dust in the air flow, so as to reduce the frequency of cleaning the composite filter screen 92.

[0044] refer to Figure 2 Composite filter 92 comprises a filter layer 921, an activated carbon layer 922, and a photocatalyst filter 923. The activated carbon layer 922 is located between the filter layer 921 and the photocatalyst filter 923. The filter layer 921 is located on the side of the activated carbon layer 922 closest to the filter grille 91, while the photocatalyst filter 923 is located on the side of the activated carbon layer 922 closest to the UV lamp 93. The filter layer 921 is a HEPA filter that filters foreign matter larger than 0.3 microns and provides high ventilation performance, improving airflow efficiency. The activated carbon layer 922 adsorbs organic matter from the air, reducing its ingress into the water tank 4 and reducing the frequency of replacement of the physical filtration system 6. One side of the photocatalyst filter 923 is illuminated by the UV lamp 93. When the UV lamp 93 is turned on, the photocatalyst filter 923 cooperates with the UV lamp to oxidize and separate organic matter and bacteria, thereby improving the quality of the water vapor entering the condensation chamber 2.

[0045] The implementation process of this embodiment:

[0046] During the water production process, the fan 3 converts the air with water vapor into an air flow through the air inlet 11 of the housing 1 into the front box 7, and passes through the filter grille 91, the composite filter 92 and the ultraviolet lamp 93 in sequence, so that the foreign matter content in the air is reduced. Then, the evaporator 21 condenses the water vapor in the air flow into water droplets, which are collected on the evaporator 21 and flow down to the collection tank 24, and then enter the water tank 4 for storage. When it is needed, the water outlet solenoid valve 51 is opened, and the water pump 5 works to push the water in the water tank 4 through the physical filtration system 6 and then to the electronic refrigeration ice bladder 52. Or heating element 53, and then flows out from the water outlet head 54; when it is necessary to sterilize the condensation box 2, first remove the filter grille 91 and the composite filter screen 92 in the front box 7, then clean the filter grille 91 and install the filter grille 91, start the fan 3, and after forming water mist at the position of the evaporator 21, spray the sterilizing gas through the release nozzle 81. When the sterilizing gas reaches the condensation box 2, stop the fan 3, so that the sterilizing gas and the water mist are fully combined to sterilize the condensation box 2 and the evaporator 21, thereby reducing the amount of bacteria entering the water tank 4 and reducing the replacement frequency of the physical filter system 6.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
