个性化加湿器逆向毕业论文

当自来水进入加湿桶后，水位逐渐上升。在加湿器电极上通电，当水位漫过电极后，电极之间通过水的导电性而构成电流回路，并把水加热至沸腾，输出洁净蒸汽。随道蒸气输出，水位逐渐降低。这时进水阀通电打开，再次进水，直到合适的水位，并继续产生蒸汽。当加湿桶中的矿物质浓度越来越高时，排水阀自动打开，排去废水，加湿器再次补充新水，并继续加湿工作过程。

是的。

加湿器作为增加室内空气湿度的生活小家电，加湿器具有缓解干燥环境、辅助补水等作用，是冬季我国北方居民改善家居环境的必备电器。

遗憾的是，很多人对加湿器缺乏正确的认知，加湿器在国内仍属于新兴品类，截止日前，渗透率仅10%，与欧美日等发达国家普遍20%以上的渗透率相差甚远。

加湿器小贴士：

1、别使用自来水加湿。加湿器最好选择添加纯净水或蒸馏水，也可以用凉开水，以减少细菌滋生。

2、别给加湿器“加料”。加入风油精、板蓝根、香精、醋或消毒剂，都是不可取的。它们有的具有腐蚀作用，影响加湿器使用寿命；

有的其颗粒散发空气中被人体吸入，轻则刺激呼吸系统，重则引起皮肤和肺部的过敏。尤其是有先天性过敏体质及患有支气管哮喘病的人群，更容易被刺激，引发咳嗽甚至哮喘。

3、别把加湿器当补水保湿美容仪。如果和人靠得太近，加湿器高速喷出的蒸汽会将细小颗粒物直接送入人体肺部，引发疾病。使用时，加湿器最好放得远一些，既不要对着脸也不要放床头。

加湿器其工作原理是将水在加热体中加热到100度，产生水蒸气，用风机将蒸气送出。所以电加热式加湿器是技术最简单的加湿方式，缺点是能耗较大，不能干烧，安全系数较低、加热器上容易结垢。市场前景不容乐观。电热式加湿器一般和中央空调配套使用，一般不单独使用。

其湿度环境经过三个过程：

1．产生蒸汽：通过电加热使水沸腾产生蒸汽。

2．控制：通过加湿器配有的微机控制蒸汽的产生及供应。

3．传播：通过蒸汽扩散装置把水蒸汽送入空气处理机或风管内的气流。

小型加湿器使用的注意事项：

1、超声波加湿器使用纯净水加湿，因为很多区域水质较硬也就是说钙镁离子含量高，加上水厂处理水时使用漂白粉等等一些净水剂，这些成份对加湿器加湿而言，非常不利。

2、定时更换水箱中的陈水，因为水存放时间过长，水质会了生变化，所以长时不使用时，水箱及水槽中勿放水。

3、请勿在水箱中加入劣质添加剂（如香水），容易造成水箱和底座着水部位出现裂缝，影响机器正常工作。

4、加湿器收藏时请将着水部位清洗，擦干，要是放置通风处风干后装入包装箱。

有用的。

1、加湿器的作用就是增加空气中的含水量，但要注意喷雾式、热蒸发式是没有用的，除了弄湿地面没什么用处。

现在流行的是超声波加湿器，它采用超声波高频震荡，将水雾化为1-5微米的超微粒子，通过风动装置，将水雾扩散到空气中，使空气湿润并伴生丰富的负氧离子，能清新空气，增进健康，一改冬季暖气的燥热，营造舒适的生活环境。

2、使用加湿气器的优点它可以给皮肤补充流失的水分，最好的方法是在晚上使用。在睡前六小时将加湿器打开，临睡时关掉。使用时注意离人体一米左右，尽量远离各种电器。

保养

1、超声波加湿器使用纯净水加湿，因为很多区域水质较硬也就是说钙镁离子含量高，加上水厂处理水时使用漂白粉等等一些净水剂，这些成份对加湿器加湿而言，非常不利，一部分钙镁离子随水雾一起喷出，弥散在物体表面和地面上，干燥后形成“白粉”状的水垢。

另一部分沉淀在换能片及水槽表面，形成固体水垢，这都是水质不纯造成，而且换能片表面结垢后，会影响加湿效果，甚至不及时清洗会导致换能片负荷加，烧坏换能片及电子原件。

2、定时更换水箱中的陈水，因为水存放时间过长，水质会了生变化，所以长时不使用时，水箱及水槽中勿放水。

3、请勿在水箱中加入劣质添加剂（如香水），容易造成水箱和底座着水部位出现裂缝，影响机器正常工作。

加湿器 Humidifier A humidifier is a household appliance that increases humidity (moisture) in a single room or in the entire home. There are point-of-use humidifiers, which are commonly used to humidify a single room, and whole-house or furnace humidifiers, which connect to a home's HVAC system to provide humidity to the entire humidifiersThe most common humidifier, an "evaporative" or "wick humidifier", consists of just a few basic parts: a reservoir, wick and are common to most humidifiers and come in different shapes and sizes. The reservoir is a containing tank of water filled prior to operation, and provides the water for the moisture output. Other types have a continuous feed from a water wick is a filter that absorbs water from the reservoir. Evaporation of water from the wick is dependent on relative humidity. A room with low humidity will have a higher evaporation rate compared to a room with high humidity. Therefore, this type of humidifier is self-regulating: As the humidity of the room increases, the water vapor output naturally decreases. These wicks regularly need cleaning and replacement — if this does not happen, the humidifier stops humidifying the area it is in and the water in the tank remains at the same fan is adjacent to the wick and blows air onto the wick, thus aiding in the evaporation of the water within the wick.[edit] Other types of humidifiersOther types of humidifiers include:Vaporizer (Steam Humidifier) (Warm Mist Humidifier) — Boils water, releasing steam and moisture into the air. A medicated inhalant can also be added to the steam vapor to help reduce coughs. Vaporizers are more healthful[1] than cool mist types of humidifiers because steam is sterile and free from minerals. Vaporizers use more electricity to boil the water. Impeller Humidifier (Cool Mist Humidifier) — A rotating disc flings water at a diffuser, which breaks the water into fine droplets that float into the air. Ultrasonic Humidifier — A metal diaphragm vibrating at an ultrasonic frequency creates water droplets that exit the humidifier in the form of a cool fog silently. Ultrasonic Humidifiers should be cleaned regularly to avoid bacterial contamination which may be projected into the air. Impeller and ultrasonic humidifiers do not selectively put water in the air, they also add any suspended material in the water to the air such as microorganisms and minerals. The amount of minerals and other materials can be greatly reduced by using distilled water, though no water is absolutely pure. Filters may also reduce the amount of material but the EPA warns, "the ability of these devices to remove minerals may vary widely."[2] Depending on the volume, this dust may have negative health effects. Wick humidifiers trap the mineral deposits in the HumidifiersFor buildings with a forced-air furnace, a humidifier may be built right into the furnace. They can also protect wooden objects, antiques and other furnishings which may be sensitive to damage from overly dry air. In colder months, they may provide substantial energy savings, since as humidity increases, occupants feel warm at a lower temperature. These units are typically called bypass humidifiers (because they are connected between the heated and cold air return ducts, using the pressure difference between these ducts to cause some heated air to make a bypass through the humidifier and return to the furnace). The humidifier should usually be disabled during the summer months if air conditioning is used; air conditioners partially function by reducing indoor humidity. There are three basic styles:Drum style: A pipe brings water directly to a reservoir (a pan) attached to the furnace. The water level in the pan is controlled by a float valve, similar to a small toilet tank float. The wick is typically a foam pad mounted on a drum and attached to a small motor; hot air enters the drum at one end and is forced to leave through the sides of the drum. When the hygrostat calls for humidity, the motor is turned on causing the drum to rotate slowly through the pan of water and preventing the foam pad from drying out. Advantages include: Low cost Inexpensive maintenance (drum-style pads are cheap and readily available)[citation needed] Disadvantages include: Requirement for frequent (approximately monthly) inspections of cleanliness and pad condition Water evaporation even when humidification is not required (due to the pan of water which remains exposed to a high velocity air stream) Mold growth in the pan full of water (this problem is exacerbated by the large quantity of air, inevitably carrying mold spores, passing through the humidifier whether in use or not). For the latter reason especially, drum-style humidifiers should always be turned off at the water supply during summer (air conditioning) months, and should always be used with high quality furnace air filters (MERV ratings as high as possible to ensure small numbers of mold spores reaching the humidifier's pan) when the water supply is turned Wheel Style: Very similar in design to the drum style humidifiers, this type of furnace humidifier replaces the foam drum with a number of plastic discs with small grooves on both sides. This allows for a very large evaporative surface area, without requiring a great deal of space. Unlike the drum style humidifiers, the disc wheel does not need replacing.[1] Advantages include: Very low maintenance (basin of humidifier should be cleaned out periodically, unless automatic flushing device is installed) No regular replacement of parts necessary Higher output due to large evaporative surface area Can be installed in hard water situations Maintains efficiency throughout lifespan Disadvantages include: Higher price Water evaporation even when humidification is not required (due to the pan of water which remains exposed to a high velocity air stream) Flow-Through Style (also known as "biscuit style" or many other, similar variant names): A pipe brings water directly to an electrically-controlled valve at the top of the humidifier. Air passes through an aluminum "biscuit" (often called a pad; using the term "biscuit" to emphasize the solid rather than foamy form) which is similar to a piece of extremely coarse steel wool. The biscuit has a coating of a matte ceramic, resulting in an extremely large surface area within a small space. When the hygrostat calls for humidity, the valve is opened and causes a spray of water onto the biscuit. Hot air is passed through the biscuit, causing the water to evaporate from the pad and be carried into the building. Advantages include: Reduced maintenance (new biscuit only when clogged with dust or mineral deposits, typically once per year) Lack of a pan of potentially stagnant water to serve as a breeding ground for mold as with a drum-style humidifier No incidental humidification caused by a constantly-replenished pan of water in a high velocity air stream Reduced requirement for expensive air filters Uses no electricity Disadvantages include: A somewhat higher purchase price Manufacturer and model-specific replacement biscuits versus the relatively generic drum-style pads A portion of the water supplied to the unit is not evaporated. This can generate a considerable amount of waste water, and does require connection to a drain. Disadvantages and risksThe use of a humidifier can allow the reproduction of dust mites or the growth of harmful mold, which can be especially harmful for children and the elderly. The relative humidity should be kept between 30% and 50%. [3]. Can also cause Hypersensitivity pneumonitis (humidifier lung) [4]Some humidifiers now use Microban technology to reduce mold and bacteria growth within the EPA provides detailed information of the risks as well as recommended maintenance procedures.[5]Some humidifiers have no silent controller that measures and controls relative humidity. A humidistat may be used to control either humidifying or dehumidifying equipment by the regulation of electric or pneumatic switches, valves, or electronic humidistat includes a sensing element and a relay amplifier. The sensing element consists of alternate metal conductors on a small flat plate. An increase or decrease of the relative humidity causes a decrease or increase in the electrical resistance between the two sets of conductors and the change in resistance is measured by the relay alsoDehumidifier HVAC Hygrometer for measuring humidity Humidifier fever Humidistat Ioniser Misting fan
