The water pump 25 injects water into a flow-through region of the humidifying wick, where the water flows in liquid form from an upper portion of the humidifying wick to a lower portion of the humidifying wick, and is also provided with an immersion region on at least one side thereof, to which the injected water is diffused through the flow-through region. Wherein the material of humidification core is that easy water takes place to soak and spreads, when the regional liquid water that exists that flows through, because the material characteristic of humidification core, can soak and spread to be located the regional one side of flowing through, or the infiltration region of both sides, when the air is through the infiltration region or the regional time of flowing through, can take away partial moisture and form humid air, when local wind speed is higher, the liquid drop can be taken away through the regional air of flowing through to the part. The first water adding part is used for humidifying the flowing area and the immersion area in two modes, so that the characteristic of the humidifying core body can be effectively utilized, the humidifying effect is improved, and the structure of the control and water discharging pipe is simplified. Compare in conventional air conditioner thermantidote, in this embodiment, the water pump volume of drawing water is showing and is greater than the conventionality, because the water in the chamber that catchments is through the processing that adjusts the temperature, the rivers that the water pump adjusted the temperature to humidification core upper portion, in order to ensure that core upper portion keeps humidity during one side, on the other hand is to add the core to the water after adjusting the temperature as much as possible to reduce or improve the temperature of core, thereby improve humidification efficiency or improve the air-out temperature, thereby improve user's use and experience.
In some embodiments, as shown in fig. 3, 4 and 6, a liquid dropping core 30 capable of absorbing moisture is disposed between the humidifying core 21 and the air outlet 12, the liquid dropping core 30 is a folded moisture-absorbing nonwoven fabric, and may be replaced by other moisture-absorbing materials such as moisture-absorbing paper, and the nonwoven fabric is coated with a hydrophilic material; a water receiving chamber 31 is provided below the drip core 30, and when the drip core 30 absorbs excessive water, the water converges and flows into the water receiving chamber 31. The water with liquid in the humidifying core 21 is absorbed and stored in the humidifying core through the humidifying device, when air flows through the humidifying core, particularly high-pressure or high-flow-rate air flows locally occur, liquid drops are carried out of the humidifying core, the liquid drop removing core 30 is arranged behind the humidifying core, and the carried liquid drops can be immersed into the liquid drop removing core and cannot be discharged from an air outlet of an air duct. When the liquid drops are air passing through a wet non-woven filter material, the liquid drops are formed at a position with high wind pressure and are blown out due to the non-uniform local wind field. The liquid drops can be influenced by gravity to descend, and if the liquid drops are dropped on the body of a user or blown down to a place where an air-conditioning air cooler is placed, traces of the liquid drops or liquid loading can be generated. The liquid drops mentioned in the invention are different from ultrasonic humidification, the liquid drops are in the order of mu m, can completely flow along with air, cannot be separated from the air to form liquid drops blown out of an air outlet, and can be further condensed into the liquid drops mentioned in the invention when the condensation condition is met; the droplets mentioned in the present invention are also different from water vapor formed by evaporation, which is transparent in itself, presents a haze when cooled, and condenses on cold surfaces. Humidification core 21 is because for adjusting the temperature, can have the water after the excessive temperature adjustment by the pump to the core to the water content of humidification core 21 has been showing to increase, when fan 13 adopted higher windscreen, produces easily and blows out the liquid drop condition, so increase and remove the liquid drop module and can show the improvement and avoid the liquid drop to blow out the wind gap, or blow the condition on the human skin, avoid these extremely poor user experience.
The humidifying core 21 adopted in the embodiment is formed by folding non-woven fabrics, when the first water adding part 22 in the humidifying device drops water to the humidifying core 21, the humidifying core 21 is partially provided with liquid drops, and the liquid drops can diffuse to wet the non-woven fabrics at farther positions due to being immersed in the non-woven fabrics, so that air can take away some water to form wet air through the non-woven fabrics with the liquid drops or the non-woven fabrics which are wetted due to diffusion. As will be appreciated by those skilled in the art, in other embodiments, humidifying core 21 may be a wet film or curtain, or the like, with liquid droplets localized and forming a wet film or curtain without liquid droplets due to immersion further away.
Specifically, in some embodiments, the dewetting core 30 is a folded absorbent nonwoven fabric that is folded to form a core that has characteristics that facilitate the immersion of the dewetting droplets, and the immersed droplets cause the dewetting core to become wet, thereby causing the air to become more wet as the wet air passes through the dewetting core, thereby carrying away the moisture from the dewetting core. On the one hand, the humidifying efficiency is increased, on the other hand, the liquid drops can be prevented from being blown out of the air outlet, and extremely poor user experience is formed.
Further, in some embodiments, the nonwoven fabric from which the droplet core 30 is removed is coated with a hydrophilic material to more effectively allow for water ingress; in some embodiments, a water containing cavity 31 is provided below the drop removing wick 30, and when the drop removing wick absorbs too much water, the water converges and flows into the water containing cavity 31, and after the water is evaporated above the drop removing wick, the water in the water containing cavity is immersed and flows upwards. A structure for limiting the upward immersion of water is provided at the water-contacting portion of the core body 30, for example, the sectional area of the core body for removing droplets immersed in water is reduced, and a plurality of columnar bodies of water are contacted; or a plurality of cylindrical cavities are hollowed out, so that the sectional area of upward transfer of the immersion liquid is reduced, the diffusion of water to the liquid drop removing core body is controlled, and new liquid drops are prevented from being formed at the liquid drop removing core body 30. Specifically, the equivalent diameter of the liquid droplets blown out by the wet air includes 0.01 to 0.59 mm, the liquid droplets are small and can be easily absorbed by the core of the liquid droplets, when the wind speed is high, the liquid droplets are occasionally blown out to be extra large, the situation is less, and the general liquid droplet range is the above range.
Further, as shown in fig. 3 and 6, in some embodiments, the distance between the dewetting wick 30 and the humidifying wick 21 is kept, and generally, the larger the distance is, the more beneficial the dewetting wick 30 is to fall down due to gravity or to be immersed and absorbed by the lower part of the dewetting wick 30; however, for design and manufacturing convenience, a certain distance D is maintained, and in some embodiments, the distance D is in the range of 1 to 95 mm, and as shown in fig. 1, the distance D is 2 mm. The distance can be kept, so that the water on the humidifying core body can be prevented from being immersed on the liquid drop removing core body to influence the liquid drop removing effect.
Further, in order to completely, or more effectively, remove the liquid droplets, the liquid droplet removing core 30 needs to be set for different humidification modes, and particularly, the liquid droplet removing core at the lower portion of the liquid droplet removing core needs to be adapted to the shape of the air duct, so as to prevent the air in the air duct at the lower portion from carrying the liquid droplets away from the air outlet; for conventional tunnel forms, in some embodiments of the present disclosure, the ratio of the cross-sectional area of the dewrinkler core 30 in the direction perpendicular to the tunnel cross-sectional area is 85% to 100%. As shown in fig. 1, this embodiment takes a spacing D of 99%.
In combination with the above embodiments, in the technical solution disclosed in the present invention, there are at least two cases: when the first water adding part 22 drops liquid water into the humidifying core 21, a water-rich area is easily formed in the flow-through area, and when the local wind pressure or wind speed is high, wet air with liquid drops is easily formed at the local wind pressure or wind speed, and the fan 13 is an axial flow fan which is formed with annular air supply fluid, and a local high wind speed area is formed at the annular air, that is, in combination with the attached drawings, at the position where the humidifying core 21 and the annular air flow are overlapped, particularly, the position where the flow-through area of the humidifying core and the annular air flow are overlapped forms a local high wind speed, and on the other hand, the humidifying core is saturated with water in the flow-through area, so that the situation that liquid drops are easily carried out by air at the overlapped part of the air-supply area and the flow-through area, that is.
When the second water adding part is immersed into the water to be absorbed into the humidifying core 21, a water-rich area is formed at the lower part of the humidifying core 21, as shown in fig. 3 and 6, a tapered air duct is arranged between the humidifying core 21 and the fan 13, an included angle between an upward inclined wall surface of the lower wall of the air duct and the axial direction of the fan is an angle a, the range of the angle a is 18-55 degrees, in a specific embodiment, the angle is 28 degrees, which is beneficial to the reliability of the structural design, and simultaneously improves the overall wind speed, thereby achieving more effective humidification. After the fan 13 sucks air from the air inlet, air is supplied along the air duct direction, because the lower wall of the air duct is inclined upwards, a concentrated high-air-speed area is formed at the position close to the wall by the coanda effect air, an air blowing area is formed at the position, close to the second water adding part, of the lower wall of the air duct, extending to the lower part of the humidifying core body 21, and the humidifying core body 21 at the position is contacted with the water body to be absorbed in the water collecting cavity 28 to form a region with a large amount of water content, so that the condition that liquid drops are brought out by the air easily occurs at the overlapped part of the air blowing area and the lower part of the humidifying core body 21, namely the air is overlapped to form.
The invention also provides a control method of the air conditioner air cooler, which is applied to the air conditioner air cooler and specifically comprises the following steps: under the condition of starting the air-conditioning air cooler, starting a water pump T1 for a time length, wherein the time length of T1 ranges from 15 seconds to 350 seconds; 45 seconds in some embodiments; after the water pump is started or the water pump is started, the temperature adjusting device is started; and starting the fan to supply air after or when the water pump is started;
the water pump is stopped to operate for T2 time length after the circulation operation, and then the water pump is started for T3 time length; during the running time length T2 of the water pump, the fan runs, and the temperature adjusting device keeps running; the pump on time period T3 ranges from 3 seconds to 50 seconds, and in some embodiments 10 seconds. And when the water pump starting time length T3 is reached, stopping the water pump from running for a time length T2, and starting the water pump again for a time length T3. So as to reciprocate. Wherein T1> T3.
Under the condition of initial opening, the humidifying core body 21 is dry, and needs a large amount of water to fully soak the humidifying core body, so the time length of T1 is long and is obviously longer than the time length of T3; when the operation is stable, normal humidification can be kept without needing large injected water amount.
In some embodiments, a temperature detection probe is disposed in the water collecting cavity 28 for detecting the temperature of the water to be humidified, and considering the operation time length T2 and T3, when the time length T2 is not reached and the temperature of the water reaches the set requirement, the water pump is turned on according to the temperature of the water, and the operation time length of the water pump is T3. That is, compromise under the condition of cooling or intensification, when the water temperature reached and to have cooling or intensification effect, need not wait for humidification core 21 not to satisfy the humidification requirement just to carry out the water yield and pour into to adjust the temperature of core, thereby further improve user experience.
In some embodiments, in order to further improve the user experience, in the case that the user initially turns on the air-conditioning air cooler, there is a good humidification and cooling/warming experience, and the control method includes turning on the temperature adjustment device T4 for a long time before turning on the water pump for the first time, heating or cooling the water in the water collection chamber 28, turning on the water pump T1 for a long time after the predetermined time T4 is reached, and simultaneously turning on the fan for operation. By adopting the mode, when a user starts to use, the water body and the humidifying core body reach the lowest temperature, so that the air outlet temperature and the humidifying quantity have the best user experience under the worst environment condition of the user, and the product acceptance is improved.
Further, the preset time period T4 of the thermostat is factory set, and in this operating time period, the temperature of the water in the water collecting chamber 28 can reach the set temperature. At this point, a better user experience is enabled.
Furthermore, the duration time of the preset time T4 of the temperature adjusting device is set by the control system according to user habits, the habits of the user are learned through the artificial intelligence AI, the next action of the user can be predicted and certain accuracy can be kept, or the room central control system is set according to the user habits, so that the user experience is further improved.
